The lower ends of the locking elements 72 are down from the extending part 63, and the rear parts of the lower ends of the formed protrusions (not shown) to secure the cover 53. In addition, the locking elements 72 are tightened due to Wed the STV preload, such as springs forming part of the drive mechanism, locking elements, so that the lower ends turn back.

The upper surface 66 is made curved upward in an arcuate shape and is inclined upward from the front side (upstream) to the rear side (the downstream side).

The side surface 67 formed for a gradual opening and extending from the upper side to the lower side relative to the front surface 65. The lower ends of the side surfaces 67 are held to the upper part extending part 63.

Closed portion 68 is made in the shape of the wall and divides the portion 56 to accommodate the dust between the closed part and the hub 69 of the first filter.

Node 69 of the first filter includes a frame 81 of the first filter, made of hard synthetic resin, etc. in a plate shape and a flat first filter 82 to filter as mesh (one) primary filter attached to the frame 81 of the first filter. Node 69 of the first filter is located on the lower side as the side cover 53 is relatively closed part 68.

The frame 81 of the first filter includes as an integral part of the frame 84 of the first filter front side (side stream)located on the front side, and the frame 85 of the first filter in the rear side (the side downstream), located on the rear side, and bent to the formation of the first inclined surface 86, to which is attached the first filter 82. The frame 81 of the first filter includes an outer peripheral edge that is installed flush with the inner surface portion 61 of the main body casing without gaps. The frame 81 of the first filter is to tilt upward from the front side to the rear side.

The frame 84 of the first filter front side is made in the form of a grid containing a set of first ventilation holes 84a on the front side (the upstream side) as vents for the formation of the air channel 57, which connects the upstream side and the downstream side of the first filter 82, and has a flat shape. The lower end as the front end of the frame 84 of the first filter front side is in contact with the inner surface of the extending part 63, located under the front surface 65 of the part 61 of the main body casing on the bottom side of the hole 71 for sucking air. In addition, the frame 84 of the first filter front side is inclined at an angle not more than 45 degrees from the side view relative to the direction of the holes on the side of the inner surface portion 61 of the main body housing holes 71 for suction of air, i.e. relative to the horizontal direction as the axial direction of the direction of the arrow X) of the flow channel. The frame 84 of the first filter front side is located inside the position of A protrusion shaped holes 71 for sucking air through the position on the upper side of the first vent holes 84a of the front side and the upper end, continuing to the frame 85 of the first filter back. The lower end of the frame 84 of the first filter front side is in contact with the top section on the side of the front end of the cover 53 and is supported by a cover 53.

Frame 85 of the first filter, the back side is made in the form of a grid containing a set of first ventilation holes 85a rear side (side downstream) as vents for the formation of the air channel 57, which connects the upstream side and the downstream side of the first filter 82, and has a flat shape. Frame 85 of the first filter back is bent upward relative to the frame 84 of the first filter front side. In addition, the upper end as the rear end of the frame 85 of the first filter back passes to the upper side of the outer side of the position of A protrusion shaped holes 71 for sucking air and becomes rotatable shaft 85b, both ends of which are supported in the axial direction can be rotated on the side surfaces 67 and 67 part 61 of the main body casing. Therefore, the node 69 of the first filter is capable of turning in the direction of up-down with respect to part 61 of the main body casing. Frame 85 of the first filter rear side is inclined at an angle not more than 45 degrees from the side view and more of the frame 84 of the first filter front side relative to the direction of the opening side of the inner surface portion 61 of the main body housing holes 71 for suction of air, i.e. relative to the horizontal direction as the axial direction (the direction of arrow X) of the flow channel. Therefore, the first inclined surface 86 is fully intersects with the direction of the opening side of the inner surface portion 61 of the main body housing holes 71 for suction of air, i.e. the horizontal direction as the axial direction (the direction of arrow X) of the flow channel at an angle not more than 45 degrees from the side view. The state in which the first inclined surface 86 intersects with the direction of the opening side of the inner surface portion 61 of the main body housing holes 71 for sucking air at an angle not more than 45 degrees from the side view, includes a state in which, when the frame 81 of the first filter, forming a first inclined surface 86, or the first filter 82 is bent downward in an arcuate shape, the plane including the front end and the rear end of the frame 81 of the first filter or the tangent line (tangent plane) curvilinear what about the plot, intersects with the direction of the opening side of the inner surface portion 61 of the main body housing holes 71 for sucking air at an angle not more than 45 degrees. The first inclined surface 86 is inclined relative to the axial direction (the direction of arrow X) and not parallel to the axial direction (direction of arrow X) of the flow channel.

The first filter 82 is located to close the first vent holes 84a of the front side and the first vent holes 85a back. In other words, the first filter 82 is located so that at least a portion of the first filter is located inside the position of A protrusion shaped holes 71 for sucking air, and the entire outer edge is on the outer side of the position A of the guide hole 71 for sucking air.

Part 62 for fixing the filter housing is made in the form of a rectangular frame and opens and expands gradually to the rear portions of the upper surface 66, the side surfaces 67 and 67 and extending part 63. Specifically, the part 62 for fixing the filter housing separates the outlet opening 93 in rectangular form, United with the side downstream of the hole 71 for sucking air through the interior of the part 61 of the main body casing on the rear section of the housing 51 of the casing. The outlet 93 open position such is against the holes 71 for sucking air.

The extending portion 63 is made in the form of a frame and opens and expands gradually to the lower parts of the front surface 65 and the side surfaces 67 and 67. Specifically, the extending portion 63 separates the hole 95 for discharging dust to dust, United with the inner side portion 61 of the main body casing at the lower section of the housing 51 of the casing. On the rear section extending part 63 wall 63a along the width direction from right to left was formed in the position opposite to the front side part 62 for fixing the filter housing, and in this wall 63a formed hole 63b, which connects the side parts 62 for fixing the filter housing and the inner side of the extending part 63. In addition, the extending portion 63 is down on the rear more than the front. Therefore, the hole 95 for discharging dust has opening direction in a direction inclined relative to the vertical direction up and down, perpendicular to the direction of the hole (axial direction of the flow channel (the direction of arrow X)) holes 71 for sucking air and opens to the front lower side. Therefore, the hole 95 for discharging dust can have square holes larger than in the case when it is opened in a vertical direction up and down.

The body 52 of the filter is capable of when replats to the rear section of the part 62 for attaching the filter housing to cover the outlet 93. Specifically, the body 52 of the filter is located on the downstream side of the first filter 82 and connected with the side holes 71 for sucking air through the air channel 57. The body 52 of the filter includes a frame 97 filter having a rectangular shape, a corrugated filter 98, which is a filter for collecting dust from the surface as the primary (secondary) filter, mounted on frame 97 of the filter, and means for removing dust (not shown) for removing dust captured corrugated filter 98.

Frame 97 filter made for airtight closing of the gap between the body 52 of the filter and edge area of the outlet opening 93 in the condition in which the body 52 of the filter attached to the outlet 93.

Corrugated filter 98 has a corrugated shape, formed by alternating continuous connection of the front protrusions, protruding forward and rear protrusions protruding backward in the direction of the width from left to right.

Means for removing dust, for example, installed on the downstream side of the corrugated filter 98 and located so that they can move in the direction of the width from left to right relative to the corrugated filter 98, and move the tool to remove dust flips on Gavrilovna filter 98 as a result of successive passes is Denia through the sharp end sections of the rear tabs of the corrugated filter 98 for vibration corrugated filter 98, to remove dust, captured corrugated filter 98. Means for removing dust can be made to actuate manually or activate automatically after a preset time, when the electric discharge fan 27 is turned off or just before the beginning of the operation of the electrical discharge of the fan 27.

The cover 53 is made in the form of a flat plate, open up, and contains a rotary shaft 53a, the speaker on the back stretch. The rotary shaft 53a is supported in the axial direction can be rotated on the lower section of part 62 for fixing the filter housing. Therefore, the cover 53 is able to open and close the opening 95 for discharging dust due to rotation. To the upper peripheral edge of the cover 53 is attached to the sealing element 101 to collect dust with the flexibility (elasticity) for airtight closing holes 95 for discharging dust by pressure welding to the lower end of the extending part 63 in a state in which the cover 53 is closed. In addition, the front end cover 53 is formed of interacting parts 102 and 102 for engagement with the tabs on the side of the lower end of the locking elements 72 and 72.

The handle 54 is formed in the forward-backward body 51 of the casing, inside of which is part of the drive device to stop the situations of elements to actuate the locking elements 72 and 72. The upper section of the handle 54 is formed a hole 105 for opening the working buttons 104 on the outer side for actuation of the drive device locking elements in position against the rear side.

Air channel 57 is an air channel, in which the air exits from the hole 71 for sucking air into the exhaust hole 93 through the first ventilation holes 84a and 85a (first filter 82) and the body 52 of the filter (pleated filter 98).

Electric intake fan 27 is located in the direction of back and forth in the compartment 28 for the electrical discharge of the fan, so that at least part of the electric discharge of the fan is closed, essentially cylindrical cap 107 electric discharge fan, made of synthetic resin, etc. electric intake fan 27 is controlled from the control part main body as a control device (not shown)located inside the housing 25 of the main body (main body 13 of the vacuum cleaner) for actuation in operation, the installed mounting buttons 22 (Figure 4).

In the anterior segment of the cover 107 electric discharge fan in the rear part on the downstream side of the connecting holes 31 of the separation wall 26 otkrytiya hole 109 of the cover, in which is inserted the rear end of as of end of the downstream injection device 108, which, essentially, is a rectifier device having a diameter gradually decreasing from the front side as the side upstream to the back side as the hand down the stream, and the end of the downstream injection device 108, is inserted into the suction hole 109 of the lid, tightly connected with the intake side of the electric discharge of the fan 27. On the lower plot on the back cover 107 electric discharge fan 27 open outlet 110 of the cover for venting electric discharge of the fan 27.

Cover 107 electric discharge fan can be divided into many sections, such as the upper and lower parts or the front and rear sections, and can be performed so that the electric discharge fan 27 is elastically suspended inside by hanging tools etc (not shown). In addition, the cover 107 electric discharge fan can elastically supported on the lower cover 38 of the housing 25 of the main body.

Next will be described the operation and the result of the first variant of implementation described above.

First, as shown in figure 1, the dust is boric glass 36 is fixed inside the dust collection chamber 35 of the main body 13 of the vacuum cleaner, and, as shown in Figure 4, the connecting portion 15 of the node 12 of the tube connected to the suction hole 43 of the main body 13 of the vacuum cleaner, and in a state in which the sleeve 16, the sliding tube 18 and a broom 19 are connected to each other, a broom 19 is located on a floor surface, the grip 21 is clamped and set the setup button 22 is powered, and therefore, the control part main body actuates electric intake fan 27 in the specified operating mode. The operator then makes sex a brush 19 to move forward and backward along the floor surface through the sliding tube 18 by means of the grip 21.

The negative pressure created due to actuate the electric discharge of the fan 27, the effect on sexual brush 19 through the discharge device 108, the communication hole 31, the dust Cup 36, the suction hole 43 of the main body and the sliding tube 18 for sucking dust from the floor surface together with air.

This intake air is air flow suction and drawn with the dust in the dust collection Cup 36 from the hole 71 for sucking air dust Cup 36, depicted in figure 1, through the sexual brush 19, the sliding tube 18, the sleeve 16 and the suction hole 43 of the main body.

This air flow suction is supplied to the node 69 of the first filter horizontally in the direction of the holes 71 for suction of air, i.e. the axial direction (direction of arrow X) of the channel of flow indicated by the arrow W1. When this frame 81 of the first filter is inclined to intersect with the direction of the hole 71 for sucking air at an angle not more than 45 degrees and, therefore, in the intake air flow elements (vectors), passing over the surface node of the first filter (first filter 82) along the node 69 of the first filter (first filter 82) become more elements (vectors), perpendicular to the first filter 82, i.e., the elements passing through the first filter 82. Therefore, the air flow suction passes through the first filter 82, and a large part of the dust captured by the first filter 82, is separated from the first filter 82 under the force of the air flow sucked in and blown away in the direction from the hole 71 for sucking air, and together with suvimol dust air flow suction straightens up along the node 69 of the first filter (the first inclined surface 86), circular passes to the side of the closed portion 68 and is in part 56 to accommodate the dust. Consequently, a large portion (coarse dust D, such as clumps of dust) dust, sucked together with the air flow suction, scaples who is on the side of the closed portion 68 from the rear end of the node 69 of the first filter, separated from the first filter node 82 69 of the first filter and blown away by the air stream of the suction, so that the state in which the clogging of the first filter is reduced, remains. Specifically, the state in which the clogging of the first filter 82 is reduced, maintained, so that the suction power of the electrical discharge of the fan 27 is supported.

When the air flow suction, which has passed through the first filter 82, passes through the pleated filter 98, fine dust (fine dust), which cannot fully be captured by the first filter 82, is collected on the surface of the corrugated filter 98.

Then the air flow suction is released to the downstream side (the outer side) dust Cup 36 of the outlet 93 and sucked on the suction side of the electric discharge fan 27 through the communication hole 31 and the discharge device 108, depicted in figure 1, passes through the electric discharge fan 27 when it cools, becomes a stream of outgoing air and is discharged from the outlet 110 of the cover 107 electric discharge of the fan, and then produced on the outer side of the main body 13 of the cleaner casing 25 of the main body through the outlet 49 of the main body of Otdelenia for electric discharge fan and separation for the coil cord.

When cleaning is finished, the operator controls the alignment buttons 22, depicted in figure 4, to switch off the electric discharge of the fan 27.

The air flow suction is no longer valid, and, therefore, coarse dust D inside dust Cup 36 falls under its own weight on the side of the node 69 of the first filter.

When the specified number or more of coarse dust collected inside the dust Cup 36, the operator opens the cover 40 of the main body casing 25 of the main body, remove the dust Cup 36 of the dust compartment 35 of the main body, grasps the handle 54 and transfers the dust Cup 36 in position over capacity for waste, such as garbage can. Then, through actuation by the operator of the working button 104 of the locking elements 72 and 72 reteplase with interacting parts 102 and 102, and the front side of the end cap 53 is rotated downward around the rotary shaft 53a under the action of its own weight, and the aperture 95 for discharging dust opens.

In this case, as shown in figure 2, node 69 of the first filter supported by the bottom cover 53, loses its support from below in accordance with the opening to the bottom cover 53, and the front end is rotated downward around the rotary shaft 85b under the action of its own in the sa. Therefore, coarse dust D collected in part 56 to accommodate the dust on the upper side of the node 69 of the first filter, falls under its own weight and is discharged into a container for disposal on the outer side of the dust Cup 36 from the hole 95 for discharging dust. In this case, it is preferable that the dust captured by the first filter and a corrugated filter 98 of the housing 52 of the filter were removed.

After the removal of dust, when the operator rotates the cover 53 up, the node 69 of the first filter in contact with the cover 53 is also rotated upward around the rotary shaft 85b, and in the state in which the hole 95 for discharging dust completely closed by a cap 53, that is, in a state in which the locking elements 72 and 72 meshed with interacting parts 102 and 102 of the cover 53, the front end of the frame 81 of the first filter is held in contact with the inner surface of the extending part 63, located under the front surface 65 of the part 61 of the main body casing on the bottom side of the hole 71 for sucking air. In accordance with this dust removal dust Cup 36 may be used multiple times.

As described above, in the first embodiment, by locating the first filter 82 on the first inclined surface 86 at an angle of less than 45 degrees relative to sent the I holes 71 for sucking air forming a flow channel containing a horizontal element, i.e. the axial direction (the direction of arrow X) of the flow channel, so that at least a portion of the first filter is located in the position of A protrusion shaped holes 71 for sucking air inside the housing 51 of the casing, the elements, passing through the surface upstream of the first filter 82 of the air flow suction, passing into the housing 51 of the casing in the direction of the holes 71 for sucking air, become more elements, perpendicular to the first filter 82 (elements passing through the first filter 82), and the air flow suction quickly goes along surface upstream of the first filter 82 and blows off dust adhering to the first filter 82. Therefore, almost no dust adheres to the first filter 82, which may be resistant suction.

In addition, optional to post the entire first filter 82 near the hole 71 for suction air, so that the volume of the portion 56 to accommodate the dust is not reduced, the amount of dust can be provided, and the filter surface area can be increased while preventing decrease the effectiveness of the suction.

In particular, the first filter 82 is inclined at an angle less than 45 degrees relative to the direction of the hole (axial feed direction of flow (direction of arrow X)) holes 71 DL the suction air, so that the plane of projection of the air flow suction, suction in the inner part of the housing 51 of the casing from the hole 71 for suction air is not less than √2 times the plane of the ledge when the first filter is located in the direction perpendicular to the direction of the hole (axial direction of the flow channel (the direction of arrow X)) holes 71 for suction of air, the filter area can be effectively increased, and can be effectively reduced adhesion of dust to the first filter 82.

By bringing into contact of the frame 81 of the first filter, forming the first inclined surface 86 with the inner surface-side openings 71 for suction air casing 51 of the casing, the air flow suction, which was held in the housing 51 of the casing from the hole 71 for suction air can be fully directed to the surface upstream of the first filter 82 is lossless and can effectively blow the dust off of the first filter 82, so that almost no dust adheres to the first filter 82.

In addition, due to the passage of the side downstream of the first filter 82 on the first inclined surface 86 (frame 81 of the first filter) to the side downstream than the position of A protrusion shaped holes 71 for suction of air, the dust being blown off the surface upstream of the first filter 82 air in the eye of suction, can be kept in the range from the side downstream of the first filter 82 on the first inclined surface 86, where the first filter 82 is located on the side of the closed portion 68 in a state in which electric discharge fan 27 is powered, and can be reduced clogging of the first filter 82 suvimol dust.

The first filter 82 is located on the side cover 53 and is supported in the axial direction can be rotated on the housing 51 of the casing, and the first filter 82 is rotated to move the dust to the side of the hole 95 for discharging dust in the state in which the hole 95 for discharging dust open the lid 53, and therefore, the first filter 82 is rotated only by opening the lid 53 and unloads coarse dust D in the portion 56 to accommodate the dust out of the hole 95 for discharging dust, so that coarse dust D inside portion 56 to accommodate the dust can be easily removed.

In addition, the first filter 82 includes an outer edge, fully located on the outer side of the position A of the guide hole 71 for sucking air, that is, in other words, the first filter 82 is made with a size that covers the entire area of the position A of the guide hole 71 for suction air, so that the downstream side of the orifice 71 for suction air is not closed, the first inclined surface 86, the, therefore, the pressure loss in the air duct 57 inside the housing 51 of the casing can be reduced.

Then the second variant will be described with reference to Figure 5 and 6. Similar items and work, as in the first embodiment, are denoted by similar reference positions, and their description will be omitted.

In accordance with the second embodiment unlike the first variant implementation of the barrier ribs 113 and 113 are made as one unit on the frame 81 of the first filter node 69 of the first filter.

Specifically, as shown in Fig.6, these dividing ribs 113 and 113 are located on both lateral parts of the position A of the guide hole 71 for sucking air in positions opposite the openings 71 for sucking air of the first filter 82 and share the channel 114 of the flow having a width not smaller positions A ledge inside the air channel 57. The barrier ribs 113 and 113 made in the form of, essentially, right triangles on the side view, and their upper sides are essentially horizontal. Therefore, the barrier ribs 113 and 113 are designed so that their size of the protrusion gradually decreases from the front side to the rear side relative to the first inclined surface 86. In addition, these dividing ribs 113 and 113 are arranged linearly in the forward-backward Wallpaper from the side portions of the front end of the first filter 82 to both side portions of the rear end.

When electric discharge fan 27 is powered to clean because of the negative pressure generated as a result of this actuation, as shown in Figure 5 and 6, the air containing dust passes into the housing 51 of the casing (part 56 to accommodate the dust from the holes 71 for sucking air (arrow W1).

This air flow suction, which was held in the housing body straightens up along the barrier ribs 113 and 113 to the first filter 82, reliably separates the dust adhering to the first filter 82, it blows away and reduces clogging of the first filter 82.

Thus, in accordance with the second embodiment by forming barrier ribs 113 and 113, which divide the channel 114 of the stream width is not less than the position of A protrusion shaped holes 71 for sucking air on the side of the inner surface of the housing 51 of the casing in positions opposite the openings 71 for sucking air of the first filter 82, the air flow suction can reliably be sent to the first filter 82 through the channel 114 of the flow, and dust adhering to the first filter 82 may more effectively to deflate air flow suction.

Then will be described a third option, with reference to Fig.7. Similar items and work, as in the variants of implementation described above, identified under the service reference positions, and their description will be omitted.

In accordance with the third embodiment, the node 69 of the first filter of the first variant implementation is as one with a lid 53.

Specifically, the node 69 of the first filter closes the upper portion of the cover 53 and is attached to the lid 53 to rotate as a unit with the cover 53.

Therefore, after the end of treatment for removing dust captured in the dust Cup 36, when the operator grasps the handle 54, moves the dust Cup 36 in position over capacity for waste, such as trash, and operates the operating button 104, the locking elements 72 and 72 reteplase with interacting parts 102 and 102, and the cover 53, and the front end node 69 of the first filter rotates downward under the action of their weights around the rotary shaft 53a, and, consequently, the hole 95 for discharging dust opens. In the coarse dust D collected in part 56 to accommodate the dust over the node 69 of the first filter, falls under its own weight and is discharged into the container for dumping trash on the outer side of the dust Cup 36 from the hole 95 for discharging dust.

Therefore, by attaching node 69 of the first filter (first filter 82) to the cover 53 of the dust collected in the dust Cup 36 can be easily removed only by Otkrytiye 53.

The third option may not be combined with the second embodiment.

In the variants of implementation described above, the front side end (lower end) of the first filter 82 is not necessarily in contact with the front surface 65 until it is located on the outer side (lower side) of the lower end position A of the guide hole 71 for sucking air.

In addition, the closed part 68 can be made with the possibility of inclusion of the dust filter, which filter is a filter to capture dust by providing air flow suction. In this case, the area of the filter dust Cup 36 may be further increased, and its role may be shared with the first filter 82 for sustainable suction, so is more efficient dust collection.

Node 69 of the first filter may be configured to discharge dust from the hole 95 for discharging dust due to movement other than rotation. Similarly, the cover 53 may be accomplished by opening and closing holes 95 for discharging dust due to movement other than rotation. In addition, the node 69 of the first filter and the cover 53 may be made without the ability to move (rotate).

Then will be described a fourth option on the westline with reference to Fig and 9. Similar items and work, as in the variants of implementation described above are denoted by similar reference positions, and their description will be omitted.

In accordance with the fourth embodiment inside part 61 of the main body casing casing casing 51 of the first variant implementation of one air channel 117 and the second air channel 118 through which the air flow suction, split, and node 121 of the second filter is fixed instead of the closed part 68.

Node 69 of the first filter includes a flat first filter 82, which is a filtration filter as mesh (one) primary filter, and is located on the lower side of the side cover 53 with respect to the host 121 of the second filter.

Node 121 of the second filter includes a frame 123 of the second filter, made of hard synthetic resin, etc. in a plate shape, and a flat second filter 124, which is a filtration filter, as net (other) primary filter attached to the frame 123 of the second filter. Between node 121 of the second filter and the junction 69 of the first filter portion 56 to accommodate the dust separated.

Frame 123 of the second filter is formed by the second inclined surface 126, which are attached to the second filter 124. This frame 123 of the second filter includes an outer peripheral edge closely adjacent to the inwardly the surface portion 61 of the main body casing without gaps. This frame 123 of the second filter is made in the form of a grid, which includes a set of second vent holes 123a as vents for the formation of another air channel 118 connecting the upstream side and the downstream side of the second filter 124, and has a flat shape. This frame 123 of the second filter (the second inclined surface 126 is located to intersect with the frame 81 of the frame of the first filter (the first inclined surface 86) at an angle less than 90 degrees and is next to the frame 81 of the first filter (the first inclined surface 86). Therefore, the frame 123 of the second filter is for slope down from front to back. In addition, the upper end as the front end of the frame 123 of the frame of the second filter is in contact with the inner surface of the bottom portion on the front side of the upper surface 66 of the portion 61 of the main body casing. Side of the lower end as the rear end of the frame 123 of the second filter is in airtight contact with the upper end of the frame 81 of the frame of the first filter, the lower end of the frame 123 of the second filter is longer ago than the upper end portion 81 of the frame of the first filter, and is located in front part 62 for fixing the filter housing. This frame 123 of the second filter is located on the outer side (upper side) on which ogene A protrusion shaped holes 71 for sucking air that is, at the position excluding the position of A protrusion. Therefore, the portion 56 to accommodate the dust is long in the forward-backward and separated to open and expand in the upward-downward to the front side as a side upstream from the rear side as the hand down the stream.

The second filter 124 is for closing the second vent holes 123a. In other words, the second filter 124 is in position on the outer side of the position of A protrusion shaped holes 71 for suction of air, i.e. in a position excluding the position of A protrusion. While the main plot, that is 50% or more area of the second filter 124, is located at the position excluding the position of A protrusion, the same operation and effect can be obtained even if the remainder is within the provisions of A ledge.

The body 52 of the filter is located on the downstream side of filters 82 and 124 and is connected with the side holes 71 for suction of air through the channels 117 and 118.

One air channel 117 is an air channel for the flow of holes 71 for sucking air into the hole 95 for discharging dust through the first ventilation holes 84a and 85a (first filter 82) and the body 52 of the filter (pleated filter 98). Another air channel 118 is an air channel for the flow of holes 71 in which asiania air into the exhaust hole 93 through the second vent holes 123a (the second filter 124 and the body 52 of the filter (pleated filter 98) through the upstream side of the node 69 of the first filter (the first inclined surface 86).

Then will be described the operation and the result of the fourth version of the implementation.

When the operator places the sexual brush 19 on the floor, closes the gripper 21 and actuates the specified installation button 22, the control part main body controls the electric blower fan 27 in a predetermined operating mode, and when a broom 19 is moved forward and backward along the floor surface by means of the grip 21 sliding through the tube 18, the negative pressure generated by actuation of the electric discharge of the fan 27, the sexual acts on the brush 19 through the discharge device 108, the communication hole 31, the dust Cup 36, the suction hole 43 of the main body, the sleeve 16 and the sliding tube 18 and sucks the dust from the floor surface together with air, and the intake air becomes air flow suction and drawn with the dust of sexual brush 19 in the dust Cup 36 from the hole 71 for sucking air dust Cup 36, depicted in Fig, sliding through the tube 18, the sleeve 16 and the suction hole 43 of the main body.

This air flow suction passes to node 69 of the first filter horizontally along the direction of the hole 71 for suction of air, i.e. along the axial direction of the flow channel,as shown by the arrow W2 in Fig. When this frame 81 of the first filter is inclined to intersect with the direction (axial direction of the flow channel (the direction of arrow X)) holes 71 for sucking air at an angle not more than 45 degrees, so that the air stream of the suction elements (vectors), passing over the surface of the node 69 of the first filter (first filter) along the node 69 of the first filter (first filter 82), become more elements (vectors), perpendicular to the first filter 82, i.e., the elements passing through the first filter 82. Consequently, a large part of the dust captured by the first filter 82, when the air flow suction passes through the first filter 82, is separated from the first filter 82 and blown away in the direction from the hole 71 for sucking air under the action of the stream of air suction and air flow suction straightens up along the node 69 of the first filter (the first inclined surface 86 and passes to the side of the node 121 of the second filter together with suvimol dust.

In addition, the air flow suction turns up from the side of the rear end node 69 of the first filter and passes through the second filter 124 node 121 of the second filter. This is captured by the dust. Consequently, a large portion (coarse dust D, such as clumps of dust) dust, sucked together with the air flow suction, going on the side of the node tio filter from the rear end of the node 69 of the first filter, the dust is separated from the first filter node 82 69 of the first filter and blown away by an air stream suction, and clogging of the first filter 82 is reduced. Therefore, the air flow of the suction created by the actuation of the electric discharge of the fan 27 is diverted to the side of the first filter 82, the driving of which is reduced, even if the second filter 124 clogged over time, which is supported by the suction power of the electrical discharge of the fan 27. Specifically, the first filter 82 is used primarily as a filter to maintain the suction power, and the second filter 124 is used primarily as a filter to capture dust.

When part of the air flow suction (one side of the air channel 117), which has passed through the first filter 82, and the air flow suction (the other side of the air channel 118), which has passed through the second filter 124, passes through the pleated filter 98, fine dust (microscopic dust), which may not be fully captured by the filters 82 and 124, going from the surface of the corrugated filter 98.

After that, the air flow suction passes to the downstream side (the outer side) dust Cup 36 of the outlet 93 is sucked on the suction side of the electric Naga is maternova fan 27 through the communication hole 31 and the discharge device 108, depicted on Fig becomes the outlet air flow when passing through the electric discharge fan 27 in the cooling of the electrical discharge of the fan 27 and out of the outlet 110 of the cover 107 electric discharge of the fan and then goes to the outer side of the main body 13 of the cleaner casing 25 of the main body through the outlet 49 of the main body of the compartment 28 for electrical discharge fan and outlets for the coil cord.

When cleaning is completed, the operator actuates the adjusting button 22 to turn off the electric discharge of the fan 27.

The air flow suction is no longer valid, so of coarse dust D in the dust Cup 36 falls under its own weight on the side of the node 69 of the first filter and fit the part 56 to accommodate the dust between node 69 of the first filter and the node 121 of the second filter.

When the specified number or more of coarse dust collected in the dust Cup 36, the operator opens the cover 40 of the main body casing 25 of the main body, remove the dust Cup 36 of the dust compartment 35 of the main body, grasps the handle 54 and transfers the dust Cup 36 in position on the container for discharge of waste, such as garbage the first box. Then, through actuation by the operator of the working button 104 of the locking elements 72 and 72 reteplase with interacting parts 102 and 102, and the front side of the end cap 53 is rotated downward around the rotary shaft 53a under the action of its own weight, and therefore, the hole 95 for discharging dust opens.

In this case, as shown in Fig.9, the node 69 of the first filter supported by the bottom cover 53, loses support from below in accordance with the opening to the bottom cover 53, and the front side of the end cap 53 is rotated downward around the rotary shaft 53a under the action of its own weight, and therefore, the hole 95 for discharging dust opens.

In this case, as shown in Fig.9, the node 69 of the first filter supported by the bottom cover 53, loses its support from below in accordance with the opening to the bottom cover 53, and the front end is rotated downward around the rotary shaft 85b under its own weight. Therefore, coarse dust D collected in part 56 to accommodate the dust between the upper side of the node 69 of the first filter and the bottom side of the node 121 of the second filter, falls under its own weight and is discharged from the openings 95 for discharging dust in a container for disposal on the outer side of the dust Cup 36. In this case, it is preferable that the dust captured by the filters 82 and 124 and bumps is included in the filter 98 of the housing 52 of the filter were removed.

After the removal of dust, when the operator rotates the cover 53 up, the node 69 of the first filter in contact with the cover 53 is also rotated upward around the rotary shaft 85b, and in the state in which the hole 95 for discharging dust completely closed by a cap 53, that is, in a state in which the locking elements 72 and 72 meshed with interacting parts 102 and 102 of the cover 53, the front end of the frame 81 of the first filter is held in contact with the inner surface of the extending part 63, located under the front surface 65 of the part 61 of the main body casing on the bottom side of the hole 71 for sucking air. In accordance with this dust removal dust Cup 36 may be used multiple times.

As described above, in the fourth embodiment, by locating the first filter 82 on the first inclined surface 86 at an angle of less than 45 degrees relative to the direction of the hole 71 for sucking air on the side of the inner surface of the housing 51 of the casing, relative to the axial direction (direction of arrow X) of the flow channel, so that at least a portion of the first filter 82 is located in A protrusion shape of the holes 71 for suction of air, the elements, passing through the surface upstream of the first filter 82 of the air flow suction that p is oshel in the housing 51 of the casing along the direction of the hole 71 for sucking air become more elements, perpendicular to the first filter 82 (elements passing through the first filter 82), and the air flow suction passes quickly along the surface upstream of the first filter 82 and blows off dust adhering to the first filter 82. Therefore, almost no dust adheres to the first filter 82, and even if the party of the second filter 124 (another air channel 118) clogged, the air flow suction can be discharged to one side of the air channel 117, so that may be sustained suction.

By locating the second filter 124 on the second inclined surface 126 that is located along the direction crossing the first inclined surface 86, together with the air flow suction, straighten to pass in one direction along the first filter 82 by the first filter 82, the dust contained in the air stream of the suction and the dust blown off of the first filter 82, collides with the side of the second filter 124 properly and can effectively be captured by that party of the second filter 124.

Therefore, not necessary to post the entire first filter 82 near the hole 71 for suction air, so that the volume of the portion 56 to accommodate the dust is reduced, the amount of dust can be secured, and the area of the filter can be increased at the expense of the first f is ltra 82 and the second filter 124 while preventing decrease the effectiveness of the suction.

Through the location of the second filter 124 on the site, excluding the position of A protrusion, the air flow suction, which was held in the housing 51 of the casing from the hole 71 for sucking air passes directly to the second filter 124, so that clogging of the second filter 124 can be prevented in the beginning.

In addition, through a side downstream of the first filter 82 on the first inclined surface 86 (frame 81 of the first filter) to the side downstream than the position of A protrusion shaped holes 71 for sucking air in a state in which electric discharge fan 27 is powered, the dust being blown off the surface upstream of the first filter 82 air flow suction can be maintained in the range from the side downstream of the first filter to the first inclined surface 86, where the first filter 82 is not located on the side of the second inclined surface 126, and a driving the first filter 82 this suvimol dust may be reduced.

By locating the frame 81 of the first filter, forming the first inclined surface 86, and part of the frame 123 of the second filter, forming a second inclined surface 126 to intersect each other at an angle not more than 45 degrees, dust, slowema without sticking to the first filter 82, is faced with the second filter 124 is when crossing at an angle not more than 45 degrees and reliably captured by the second filter 124, so dust can more effectively be collected without hang inside the case 51 of the casing (part 56 to accommodate the dust).

In addition, the second filter 124 has a surface direction, inclined downwards, while the hole 95 for discharging dust turned down, so that when the cover 53 is opened, and the first filter 82 is rotated, coarse dust D inside portion 56 to accommodate the dust located between the second filter 124 and the first filter 82, can easily fall out of the hole 95 for discharging dust.

In addition, the first filter 82 includes an outer edge, fully located more on the outer side than A position of the guide hole 71 for suction of air, i.e. the first filter 82 is made with a size that covers the entire area of the position A of the protrusion, so that the downstream side of the orifice 71 for suction air is not closed, the first inclined surface 86, and the pressure loss in the air channels 117 and 118 within the housing 51 of the casing can be reduced.

Then will be described a fifth variant of implementation with reference to Figure 10. Similar items and work, as in the variants of implementation described above are denoted by similar reference positions, and their description will be omitted.

In accordance with the fifth embodiment in contrast to the fourth variant of implementation, the node 121 of the second filter (second filter 124) support zivaetsja in the axial direction can be rotated on the part 61 of the main body casing body 51 of the casing as a unit with the hub 69 of the first filter (first filter 82).

Specifically, the rear end (lower end) of the frame 123 of the second filter 121 is connected as one piece with the rear end (upper end) of the frame 85 of the first filter in the rear side of the frame 81 of the first filter. The lower end of the frame 123 of the second filter 121 becomes rotatable shaft 123b supported in the axial direction can be rotated and tightened by means of pre-filter, such as a torsional spring (not shown). Therefore, the node 121 of the second filter and the node 69 of the first filter are drawn in a downward direction, i.e. in the opposite direction to the upstream side of the second filter 124 to the hole 95 for discharging dust, while the angle of intersection between these nodes filter is saved.

Then, as shown by an imaginary line in Figure 10, in a state in which the hole 95 for discharging dust closed by a cap 53, the cover 53 supports the node 69 of the first filter from the bottom, and therefore the node 121 of the second filter is also indirectly supported at the intersection with the hub 69 of the first filter at a given angle and is locked from turning. Therefore, the node 121 of the second filter is blocked from rotation, confronting the preload cap 53 in the position in which he is able to turn to the side of the hole 95 for discharging dust, that is, in this embodiment, on the end side opposite to the side of the hole 95 for VYGR the conditions of the dust in the rotation range of the node 121 of the second filter, specifically, on the side of the start position of the rotation.

When the specified number or more of coarse dust D is collected in the portion 56 to accommodate the dust in accordance with the operation of the electric vacuum cleaner 11, the operator opens the cover 40 of the main body casing 25 of the main body, remove the dust Cup 36 of the dust compartment 35 of the main body, grasps the handle 54 and transfers the dust Cup 36 in position over capacity for waste, such as garbage can. Then by actuating the working button 104 by the operator, the locking elements 72 and 72 reteplase with interacting parts 102 and 102, and as shown by the solid line in Figure 10, the front side of the end cap 53 is rotated downward around the rotary shaft 53a under the action of its own weight, and the hole 95 for discharging dust opens.

When this node 69 of the first filter and the node 121 of the second filter supported by the bottom cover 53, lose their bearings in accordance with the opening down cover 53 and rotated to the lower side of the side holes 95 for discharging dust due to preload medium preload filter, and therefore, coarse dust D collected in part 56 to accommodate the dust is pushed out and discharged from the hole 95 for discharging dust in a container for disposal on the outer side of the dust Cup 36 is evil 121 of the second filter.

Thus, in the fifth embodiment, the second filter 124 (node 121 of the second filter) is supported in the axial direction can be rotated in the housing 51 of the casing, the rotation of the second filter 124 to position the side upstream opposite the openings 95 for discharging dust in the state in which the hole 95 for discharging dust open the lid 53 when the cover 53 is opened to remove the dust coarse dust D collected in part 56 to accommodate the dust is ejected from the holes 95 for discharging dust the second filter 124, so that the dust can be removed more effectively.

In addition, the second filter 124 (node 121 of the second filter) drawn in to the side of the hole 95 for discharging dust, and in the state in which the hole 95 for discharging dust closed by a cap 53, the rotation of the second filter 124 (node 121 of the second filter is blocked, confronting the preload in the position in which the node 121 of the second filter can be turned to the side holes 95 for discharging dust, and therefore, when the cover 53 is opened, the second filter 124 (node 121 of the second filter) quickly turns to the side of the hole 95 for discharging dust when the preload, so that coarse dust D collected in part 56 to accommodate the dust, can more effectively be pushed out of the hole 95 for discharging dust.

In the fifth embodiment, described the above, node 69 of the first filter and the node 121 of the second filter can be made with the possibility of independent rotation relative to each other. In this case, by means of a separate establishment of the supporting means that supports the node 121 of the second filter in a state in which the hole 95 for discharging dust closed by a cap 53, and blocks rotation of the node 121 of the second filter in the position in which the node 121 of the second filter can be turned to the side holes 95 for discharging dust, the same operation and effect as in the second embodiment can be obtained.

Node 121 of the second filter can be made to rotate under the action of, for example, its own weight.

Then will be described a sixth variant of implementation with reference to 11. Similar items and work, as in the variants of implementation described above are denoted by similar reference positions, and their description will be omitted.

In accordance with the sixth embodiment of the fourth variant of the implementation described above, combines the barrier ribs 113 of the second variant implementation, specifically the barrier ribs 113 and 113 are made as one unit on the frame 81 of the first filter node 69 of the first filter.
