The level of technology

From the document JP 09-155239 known vacuum cleaner containing a cylindrical container and the suction tube mounted on the side surface of the container, which is based on the principle of centrifugation education savaraudoa flow along the inner surface of the container. The cleaner, which is based on the principle of centrifugation, sucks the dust and air, separates dust from air using a formed in the container swirling flow and the separated dust accumulates in the container.

It should be noted that the purified air is produced in either of two directions along the axial line of the Central section of the vorticity of the flow, namely the Central section of the container.

Known vacuum cleaner, in particular a vacuum cleaner having a cylindrical container, inside of which is formed savanaudis flow centrifugation dusty air and simultaneously collects the separated dust, has no element, clearly separating zone (region) centrifugation dusty air and the area of dust. This known vacuum cleaner sends a swirling flow generated in the zone of centrifugation dusty air, along with dust in the zone of accumulation of dust, in which n is l gradually going through swirling flow and accumulate.

Unfortunately, it is very difficult to increase the density of the dust collected by the swirling flow. In particular, there is only a shaky loose dust, and in the zone (area) of the dust is difficult to collect a large quantity.

In addition, since the known vacuum cleaner has no element for a clear separation zone (region) centrifugation dusty air and the zone (region) dust going through formed in the container swirling flow in the zone of accumulation of dust can go back to the zone of centrifugation dusty air. With this in mind, a well-known vacuum cleaner includes a container having two coaxial cylindrical sections of different diameters, a stepped section and a partition mounted on the stepped section, and the section for separation of the dust-Laden air is separated from the camera collect dust.

The air passing through the opening indicated, sequentially passes through the Central area of the cylindrical container from the camera gathering dust in the separation section to output it to the outside of the to the of Steiner. At this time, the air passing through the opening indicated, may return a small dust particles of the low weight of the camera collect dust separation section when the output of the air to the outside of the container. This fine dust clogs the filter on the output side.

The objective of the invention is to provide a dust collector and vacuum cleaner containing a cylindrical container, inside of which forms a swirling flow centrifugation dusty air with simultaneous accumulation of the separated dust, in which the density is accumulated over time, dust is increased to maximum possible value for the purpose of collecting a large quantity, and also provide reliable dust collection to prevent reverse return.

Thus, the control unit 9 can specify one of several modes of operation of the vacuum cleaner in response to a command signal received by the tubular section 3, to actuate the electric fan 8. Each worker signal on the tubular section 3 corresponds to the predetermined mode cleaner (the input value for the electric fan 8).

On the free end of the power cord 11 has a plug 14.

The tubular section 3 of the vacuum cleaner due to the vacuum generated in the main body 2 of the vacuum cleaner when the actuation of the fan 8, sucks and directs the dust-Laden air from a surface to be treated (hereinafter in the description of the mod which should be referred to as the surface to be cleaned), in the main part 2 of the vacuum cleaner.

The tubular section 3 contains a connecting tube 19, which Rethimno connected with the connecting pipe 12 of the main part 2 of the vacuum cleaner; the hose 21 for collecting dust, which is connected with the connecting tube 19; tube 22 for manual control connected with a hose 21 for collecting dust; the handle 23 attached to the tube 22 for manual control, the control panel 24 located on the handle 23; an extension tube 25, Rethimno connected to the tube 22 for manual operation; and a nozzle 26 with the suction inlet, Rethimno connected to the extension tube 25.

Connecting tube 19 is connected to the dust collector 7 via a connecting pipe 12.

The hose 21 for dust collection is flexible and has a long, elongated, essentially cylindrical shape. One end of the hose 21 (in this case, the rear end of the hose attached to the end of the connecting tube 19. The hose 21 is connected with the container via a connecting tube 19.

Tube 22 for manual control is installed between the hose 21 and the extension tube 25. One end of the tube 22 for manual control (in this case, the rear end of the tube) connected with the other end of the hose 21 (in this case, the front end of the hose). Tube 22 for manual control connected to and communicates with the dust collecting container 7 by fixing the part of the tube 19 and the hose 21.

In the operation of the vacuum cleaner 1, the user grasps the handle 23. The handle protrudes from the tube 22 for manual control and has a form that allows the user to easily grasp her hand.

In particular, the panel 24 control supplied with the switch 24A, which stops the electric fan 8, and the switch 24b, which starts the electric fan 8. Instead of the switch 24b of the control panel 24 may include a separate switch for operation at low power (not shown), the switch for operation at intermediate power (not shown) and a switch for operation in high power (not shown). The user can selectively set the operation mode of the electric fan 8 through the panel 24 of the control.

Extension tube 25 has an essentially elongated cylindrical shape and is retractable. It has a telescopic structure made by the method of rolling multiple cylindrical elements. One end of the extension tube 25 (in this case, the rear end) Rethimno connected with the corresponding end of the tube 22 for manual control (in this case, the front end of the tube). Extension tube 25 is connected to and communicates with the dust collecting container 7 through the tube 22 to the science of management, the flexible hose 21 and the connecting tube 19.

Suction nozzle 26 Rethimno connected with the other end of the extension tube 25 (in this case, the front end of the extension tube). Suction nozzle 26 can move or slide on the surface being cleaned, such as a wooden floor or carpet.

On the bottom surface of the suction nozzle 26 has a suction hole 28, which in the working position of the nozzle facing the surface to be cleaned. In addition, the suction nozzle 26 is equipped with a rotating cleaning device 29, which is installed in the suction nozzle 26 for rotation and located in the suction hole 28, and the motor 32 to actuate the rotating cleaning device 29. Suction nozzle 26 is connected with a dust collector 7 through the extension tube 25, the tube 22 for manual operation, the hose 21 and the connecting tube 19.

Upon actuation of the switch 24b is driven by the electric fan 8, which creates a negative pressure (suction pressure) inside the housing 2 of the vacuum cleaner. The specified negative pressure through the connecting pipe 12 through hose 21 for dust collecting tube 22 for manual control and extension tube 25 is transmitted to the suction hole 28 of the suction nozzle 26. When the vacuum cleaner 1 under the action of the m suction pressure transmitted to the suction hole 28, accumulated on the cleaning surface dust is sucked together with air through the suction hole 30, which ensures proper cleaning of the surface. Dusty air, which is sucked through the suction hole 28, enters the dust collector 7 for separating dust from air. Separated dust is collected and accumulated in the dust collector 7 of the vacuum cleaner 1. The dust-free air is drawn through the electric fan 8 of the dust collector 7 and out of the main part 2 of the vacuum cleaner.

As shown in figure 2-5, the container 7 according to this variant embodiment of the invention includes a container 35, the suction tube 36, the discharge tube 37, the partition 39, the first filter 41, the Cup 42, a columnar element 43, the second filter 45 and corrugated filter 48.

It should be noted that the dust collector 7 is installed in the main body 2 of the vacuum cleaner so that the axis of the cylindrical container 35 is vertically, but perhaps its location and in a horizontal direction or tilted at any angle.

The container 35 is a cylindrical container with a lid and a bottom, containing the channel 55 of the outlet air formed by the cover 35 and the partition wall 39, the camera 56 of the dust formed by the plate 35b and the Cup 42, and section 57 of separa the AI, formed by the partition 39 and the Cup 42. The bottom of the container 35, defining a chamber 56 dust collection represents the opening and closing of the cover 58. The cover 58 is a door for opening and closing the camera 56 of the dust collection. On the side wall 35C of the container 35 is articulated mechanism 61 that supports the cover 58, with the possibility of opening and closing. When the cover 58 of the dust that has accumulated in the chamber 56 of the dust is removed from the container 35.

Suction tube 36 is an inlet tube connected to the side wall 35C of the container 35 and guide the air along the inner peripheral surface of the container 35. Suction tube 36 connects the connecting pipe 12 of the housing 2 of the vacuum cleaner and section 57 of the separation inside the container 35. A passage of the suction tube 36 is directed along the tangent to concentric circles about the axis of the container 35. When the electric fan 8 is actuated to create a vacuum in the container 35, there is formed a swirling flow F.

Discharge tube 37 is connected to the container 35 is located closer to the lid 35A than the suction tube 36. Discharge tube 37 is connected to the channel 55 extending from the container 35 and air bleed hole (not shown) of the electric fan 8.

It should be noted that the suction tube 36,a discharge tube 37 and the side wall 35C is made in one piece with the container 35.

The partition 39 is a wall installed between the suction tube 36 and outlet pipe 37, and has a hole 39A (first hole), essentially concentric with the container 35. The partition 39 is retained by the container 35 and prevents the formation of swirling flow F dust-Laden air flowing in section 57 of the separation, and the immediate passage of dust-Laden air into the channel 55 of the outlet air by separating these spaces. Hole 39A is round and located perpendicular to the axis of the container 35 is essentially in the center of the partition 39. In addition, the partition wall 39 has an inner cylinder 62, located within section 57 of the separation along the axis of the container 35. The inner cylinder 62 holds the Cup 42 within the container 35. The inner cylinder 62 has a grating side surface and a large hole a connecting the space inside and outside the cylinder.

Inside the container 35 (in particular, within section 57 of separation) is the strainer 41 having the form of a cylinder, coaxial with the container. The filter 41 is located opposite the suction tube 36 and is installed in the hole 39A. In particular, the filter 41 has a cylindrical shape surrounding the side wall of the lattice of inner cylinder 62. The filter 41 prevents dust from section 57 of the separation channel 55 facing ozdoba, not only when savanaudis flow F still not spread within section 57 of the separation, for example, immediately after starting of the electric fan 8 and immediately after his stop, but, of course, also after distribution of the vorticity of the flow F.

The Cup 42 is located in the container 35 is closer to the bottom 35b, the filter 41. The Cup 42 has a cylindrical shape with a bottom and is open towards the inner surface of the bottom 35b of the container 35. The Cup 42 has a side wall 53 and bottom 54 with a hole 54A and installed with the formation of the gap 51 between the side wall and the inner surface of the container 35 and the gap 52 between the side wall and the inner bottom surface 35b.

The inner surface of the Cup 42 with bottom 35b (i.e. with the cover 58) container 35 forms a chamber 56 collecting dust. The inner surface of the Cup 42 is open in the direction of the bottom 35b (i.e. cover 58) of the container 35 and extends in this direction.

In addition, the Cup 42 connects the section 57 of the separation and the camera 56 of the dust collection through the gaps 51 and 52 between the Cup 42 and the container 35. The gap 51 is formed between the inner surface of the container 35 and the outer surface of the side wall of the Cup 42. Hole 54A in the Cup 42 is located closer to the axis of the container 35, than the gap 51. Hole 54A connects the camera 56 dust and section 57 of the separation. The gaps 51 and 52 and the hole alizeinal section 57 of the separation and the camera 56 of the dust collection. The gaps 51 and 52 is directed vorticity flux F generated in section 57 of the separation, together with the dust in the chamber 56 of the dust collection. Hole 54A returns vorticity flux F, which is directed into the chamber 56 of the dust collecting section 57 of the separation.

Columnar element 43 is a hollow circular cylinder mounted between the bottom wall 54 of the Cup 42 and the bottom 35b (i.e. cover 58) container 35 along the axis of the container 35 in the chamber 56 of the dust collection. Columnar element 43 abuts against the cover 58 to block the distribution of air between the hollow section and the camera 56 of the dust collection. Columnar element 43 can be made in one piece with the inner cylinder 62 and the hollow section can be connected with the inner space of the cylinder 62.

The filter 45 is mesh and is located in the hole 54A of the Cup 42. The filter 45 may be sufficiently rough to prevent the return of fibrous dust, such as paper and cotton fibers entering the camera 56 of the dust collecting section 57 of the separation.

In the output channel (i.e. the channel 55 extending air) between the hole 39A of the partition 39 and the outlet tube 37 is corrugated filter 48. Corrugated filter 48 picks up small particles of dust passing through the filter 41, and prevents the suction of fine dust in electric fan 8, when the swirling flow F is still nedostajucastranica within section 57 of the separation, for example, immediately after starting of the electric fan 8 and immediately after stopping.

It should be noted that under the hole 54A may be a group of holes, which includes a number of holes concentric with the center of the container 35 and located at equal distances. In addition, instead of holes 54A with the installed filter 45 can be accomplished group of holes (site filter)that includes a number of holes of relatively small diameter (for example, 5 mm in diameter or less)is sufficient to prevent the return of fibrous dust, such as paper and cotton fibers entering the camera 56 of the dust collecting section 57 of the separation.

In addition, the gap 51 and the hole 54A can not only have a ring shape along the entire periphery around the center of the container 35. In particular, the gap 51 may be formed in an arc shape along the inner periphery of the container 35. In addition, the hole 54A may be located closer to the center of the container 35, than the gap 51, and may be in the form of an arc.

In this way the dust collector 7 during operation of the electric fan 8 through the discharge tube 37 within the channel 55 of the outlet air in a vacuum. Further depression of the channel 55 through the opening 39A covered in section 57 of the separation. In addition, depression in sections 57 Sep'a is then through the suction tube 36 is passed into the tubular section 3 of the vacuum cleaner. Dusty intake air into the tubular section 3, passes in the opposite direction on the same route from the tubular section 3 of the vacuum cleaner a dust collector 7.

Dust Laden air enters the dust collector 7, passes through the inner surface of the container 35 from the suction tube 36, creating a swirling flow F in section 57 of the separation. Vorticity flux F is subjected to centrifugation to separate dust from dust-Laden air. Part of the purified air passes through the filter 41, located near the center of the swirl flow F and holes 39A, and reaches the channel 55 of the outlet air (as shown by the arrow Fr in figure 2). The remaining portion of the purified air and the separated dust moving along the circumference of the inner surface of the container 35 and passing through the gaps 51 and 52, fall into the chamber 56 of the dust collection.

Dust entering the camera 56 of the dust is collected during turbulence inside the Cup 42 and stored in such a manner that it surrounds the columnar element 43. The air entering into the chamber 56 of the dust passes through the opening 54A in the Cup 42 and is returned from the chamber 56 of the dust collection section 57 of the separation. At this time, the air flow Fc, moving out in section 57 of the separation through the opening 54A of the Cup 42, compresses the accumulated dust around the columnar element 43 in the bottom wall 54 of the Cup 42 or filter 45.

In the lesbonic 7, which forms a swirling air flow, stream Fc air returning from the chamber 56 of the dust collection section 57 of the separation, provides compression and settling of dust that has accumulated in the chamber 56 (namely in the space inside the Cup 42), the bottom wall 54 of the Cup 42 or filter 45 to increase the density of the dust and reduce its volume to accumulate a large quantity in the chamber 56 of the dust collection.

In addition, since the fibrous dust accumulates inside the Cup 42, the dust collector 7 is securely prevents the return of fibrous dusts in section 57 of the separation using vortex flow F.

In addition, the dust collector 7 is designed so that the inner surface of the Cup 42 is open and extending in the direction of the bottom 35b (i.e. cover 58) of the container 35. Thus, when the bottom 35b of the container 35 is oriented in the lower direction, the dust inside the camera 56 of the dust moves easily to the lid 58. When the cover 58 is opened, the dust can be easily removed out of the container 35.

The second embodiment of the dust collector and vacuum cleaner in accordance with the present invention is described with reference to Fig.6-9.

It should be noted that the box 7A according to the second variant of execution of the elements are the same as the structural elements of the dust collection unit 7 in the first embodiment, with the same reference numbers and symbols the crystals, repeated description of these elements is omitted.

As shown in Fig.6-9, in contrast to the dust collector 7, corresponding to the first variant implementation, the dust collection unit 7A according to the second variant of execution is set Rethimno in the casing 5 of the vacuum cleaner 1.

As shown in Fig.6-9, a dust collector 7A in this embodiment includes the container 35, the suction tube 36, the discharge tube 37, the wall 39A, the filter 41, the Cup 42, a columnar element 43, a filter 45, a ROM 46 and corrugated filter 48.

It should be noted that mounted in the main body 2 of the vacuum cleaner a dust collector 7A is oriented so that the axis of the cylindrical container 35 can be positioned both vertically and horizontally or at any angle to the vertical.

Wall 39A is a wall installed between the suction tube 36 and outlet pipe 37, and has a hole 39A is essentially concentric with the container 35. Wall 39A is retained by the container 35 and separates section 57 of the separation from the channel 55 of the outlet air to prevent the formation of vortex flow F dust-Laden air flowing in section 57 of the separation, and the immediate passage of dust-Laden air into the channel 55 of the outlet air. Hole 39A is made circular and is perpendicular to the axis of the container 35 is essentially in the center of pereg rodki 39A. In addition, the partition wall 39A has an internal cylinder A located within section 57 of the separation along the Central axis of the container 35. The inner cylinder A holds the Cup 42 and the disk 46 within the container 35. The inner cylinder 62 has a grating side surface and a large hole a connecting the space inside and outside the cylinder.

Between the filter 41 and the filter 45 has a disk 46 with the formation of a gap between it and the bottom wall 54 of the Cup 42. The disk 46 is made in the form of an umbrella, the dome of which the concave side is directed from the bottom of the Cup 42. Preferably, the disk 46 is aligned with at least part of the filter 41 and is large enough to close the filter 45, when viewed in the direction of the Central axis of the container 35.

The square bore of the gap 51 between the inner surface of the container 35 and the outer surface of the side wall of the Cup 42, denoted by S1, exceeds the area of the flow area of the gap 63 between the bottom wall 54 of the Cup 42 and the edge of the disk 46, denoted by S2, i.e. S1>S2.

The area of the flow area of the gap 52 between the inner bottom surface 35b of the container 35 and the end surface of the side wall of the Cup 42, denoted S3, exceeds the area of S1, i.e. S3>S1.

A dust collector 7A is designed so that air passes from section 57 of the separation in the chamber 56 of the dust and the ATEM returns in section 57 of the separation, moreover, the further flow, the smaller is the area of the orifice (area S3 is larger than the area S2, and the area larger than the area S2 S1), resulting in sharply reduced speed swirling flow F flowing into the chamber 56 of the dust collection.

In this way the dust box 7A, when working electric fan 8 through the discharge tube 37 on the inner side of the channel 55 of the outlet air in a vacuum. Further depression of the channel 55 through the opening 39A is set in section 57 of the separation. In addition, depression of section 57 of the separation through the suction tube 36 is passed into the tubular section 3 of the vacuum cleaner. Dusty air intake tube section 3, passes in the opposite direction on the same route from the tube section 3 a dust collector 7A.

Dust Laden air enters the dust collector 7A, passes through the inner surface of the container 35 from the suction tube 36, creating a swirling flow F in section 57 of the separation. Vorticity flux F is subjected to centrifugation to separate dust from dust-Laden air. Part of the purified air passes through the filter 41, located near the center of the swirl flow F and holes 39A, and reaches the channel 55 of the outlet air (as shown by the arrow Fr figure 6). The remaining portion of the purified air and the separated dust is moving on on the raznosti on the inner surface of the container 35 and, passing through the gaps 51 and 52, fall into the chamber 56 of the dust collection.

Dust entering the camera 56, contains not only the fibrous dust, but also small particles passing through the opening 54A and the filter 45. Fibrous dust is collected at the time of the turbulence inside the Cup 42 and stored in such a manner that it surrounds the columnar element 43.

The air entering into the chamber 56 of the dust, trying to return from the chamber 56 of the dust collection section 57 of the separation through the opening 54A in the Cup 42. However, the air passing through the opening 54A on the outside of the Cup 42 is blocked by the disk 46, located between the chamber 56 dust and section 57 of the separation, the velocity of flow decreases. Part of the air is returned to in section 57 of the separation, and the other part is connected with the vortex flow F flowing into the gap 51 to create a circulating flow Fc flowing into the chamber 56 of the dust collection.

A dust collector 7A that creates swirling of the air flow, reduces the flow rate of air returning from the chamber 56 of the dust collection section 57 of the separation, and exposes a portion of the air from the impact of the circulation flow back into the chamber 56 of the dust collection. Thus, the fine dust that is not captured by the filter 45 is returned into the chamber 56 of the dust, not getting in section 57 of the separation. In the result, this prevents the tree dust in the corrugated filter 48.

In addition, since the fibrous dust accumulates inside the Cup 42, the dust box 7A reliably prevents its return to section 57 of the separation using vortex flow F and the circulation flow Fc.

A dust collector 7A is designed so that the inner surface of the Cup 42 is open and extending in the direction of the bottom 35b (i.e. cover 58) of the container 35. Thus, when the bottom 35b of the container 35 is oriented in the lower direction, the dust inside the camera 56 of the dust moves easily to the lid 58. When the cover 58 is opened, the dust is easily removed from the container 35.

Thus, the vacuum cleaner 1 and the dust collectors 7 and 7A according to the options of implementation of the present invention have a cylindrical container 35, inside which creates a swirling flow F for centrifugation dusty air and at the same time is going to separate the dust, at the same time the density of the accumulated dust increases to the maximum possible value, allowing you to collect a large amount of dust, and in connection with reliable dust collection to prevent its return.

It should be noted that the implementation of the present invention is not limited to the use of cleaner, container type, can also be used in the vertical vacuum cleaners, handheld, portable type and other types.
