Figure 1-4 shows an external view of a cleaning device that represents the vacuum cleaner 10. The vacuum cleaner 10 is cylindrical vacuum or vacuum with the container. In General, a vacuum cleaner 10 includes a separating device 12 designed for separating dirt and dust from the air stream. Preferably, the separating device is in the 12 was a cyclone separating device and contain the external tank 14, essentially, a cylindrical outer wall 16. The lower end of the outer tank 14 is closed by a curved base 18 that can be rotated is attached to the outer wall 16. Driven by the motor fan unit designed to create a suction action to draw contaminated air into the separating device 12, is located in the rolling device 20 located behind the separating device 12. A rolling device 20 includes a main portion 22 and two wheels 24, 26 that are rotatably connected with the main part 22 and which are intended for engagement with the floor surface. The inlet tube 28, which is located under the separating device 12, provides movement of polluted air in the separating device 12 and the outlet tube 30 provides movement of air released from the separating device 12, in the rolling device 20. The mechanism 32 controls the movement of the vacuum cleaner 10 when maneuvering on the surface of the floor.

The mechanism 32 of the control contains a frame 34, which is connected with the main part 22 of the rolling device 20. Frame 34, in General, is arrow-shaped and includes an elongated main portion 36, the rear end of which is connected to the main part 22 of the rolling device 20, and a pair of side parts 38, which the environment is changed back from the front end of the elongated main portion 36 and are located at an angle to the elongated main portion 36. The slope of the front walls of the side portions 38 of the frame 34 may facilitate maneuvering the vacuum cleaner 10 near the corners of furniture or other objects protruding above the surface of the floor, as if contact with such object above the front wall of the side portions 38 of the frame 34 usually pass by the speaker of the subject and direct rolling device 20 around the speaker object.

In addition, the mechanism 32 control comprises a pair of wheels 40, interacting with the floor surface, and a control mechanism to control the orientation of the wheel 40 relative to the frame 34, and thereby control the direction of movement of the vacuum cleaner 10 over the floor surface. Wheels 40 are located behind the side portions 38 of the frame 34 and the front wheels 24, 26 of the rolling device 20. Wheels 40 can be considered a turning front wheels of the vacuum cleaner 10, and the wheels 24, 26 can be considered as the rear wheels of the vacuum cleaner 10.

In addition to controlling the movement of the vacuum cleaner 10 over the floor surface, the wheels 40 are supporting elements for supporting the rolling device 20 when maneuvering on a floor surface to limit rotation of the rolling device 20 relative to the axis perpendicular to the axes of rotation of the wheels 40 and essentially parallel to the surface of the floor, which moves the vacuum cleaner 10. The distance between the points of contact is and wheels 40 with the floor surface is larger than the distance between the contact points of the wheels 24, 26 rolling device 20 with the floor surface. In this example, the distance between the contact points of the wheels 40 with the floor surface approximately twice the distance between the contact points of the wheels 24, 26 of the rolling device 20 with the floor surface.

The control mechanism comprises a pair of levers 42 management, each of which connects a corresponding wheel 40 to the frame 34. Each lever 42 control, essentially, is L-shaped so that it is bent around the respective wheels 40. The first end of each lever 42 controls with turn connected to the end of the respective side part 38 of the frame 34, which is made to rotate about the respective axis N. Each axis is H, is essentially perpendicular to the axes of rotation of the wheels 40. The second end of each lever 42 control is connected with the corresponding wheel 40, so that the wheel 40 can freely rotate when you move the vacuum cleaner 10 over the floor surface. As shown, for example, in figure 3, the outer surfaces of the levers 42 management tilted relative to the front walls of the side portions 38 of the frame 34 at the same angle, so if the side 38 of the frame 34 comes into contact with a protruding object, the lever 42 control connected with this side part 38 may help to guide the rolling device 20 and wheels around 40 protruding object.

The panel is engaged in the mechanism also includes an elongated transverse rod 44, designed to control the rotation of the levers 42 of the control relative to their axes N, thereby to control the direction in which the vacuum cleaner 10 is moved on a floor surface. As shown in figure 5 and 6, the frame 34 includes a lower section 46 of the frame, which is connected with the main part 22 of the rolling device 20, and the upper section 48 of the frame connected with the lower section 46 of the frame. Each section 46, 48 of the frame may be made of one or more elements. The upper section 48 of the frame contains a generally flat bottom portion 50, which together with the lower section 46 of the frame forms a major part 36 and sidewalls 38 of the frame 34. The upper section 48 of the frame also includes an end wall 52, the protruding upward from the lower portion 50, and a shaped upper portion 54 that engages with the end wall 52 and protruding upward over a portion of the lower part 50. The middle part of the lateral thrust 44 is held between the lower part 50 and the upper part 54 of the upper section 48 of the frame. The transverse rod 44 so oriented relative to the frame 34 to be positioned essentially perpendicular to the main portion 36 of the frame 34 when the vacuum cleaner 10 is moved forward on the floor. Each end of the lateral thrust 44 is connected with the second end of the respective arm 42 of the control, so that the movement of the lateral thrust 44 relative to the frame 34 causes rotation of each lever 42 of the control relative to the positive axis N. In turn, this leads to a rotation of the wheel 40 relative to the end of the corresponding lateral portion 38 of the frame 34 and, accordingly, to change the direction of movement of the vacuum cleaner 10 over the floor surface.

As shown in Fig.6, the lower section 46 of the frame contains a rod 56, which runs essentially perpendicularly upward from the lower section 46 of the frame and which passes through a hole made in the lower part 50 of the upper section 48 of the frame. The upper portion 54 of the upper section 48 of the frame has a recess designed to accommodate the upper end of the rod 56. The longitudinal axis of the rod 56 that defines the Central axis P of the rotating mechanism 32 controls. The axis R of rotation essentially parallel to the axis N.

The inlet tube 28, which is intended to move contaminated air in the separating device 12, connected to the frame 34 can be rotated. The inlet tube 28 contains the speaker back section 58, which is held between the lower part 50 and the upper part 54 of the upper section 48 of the frame. Section 58 includes a hole to accommodate the rod 56 of the lower section 46 of the frame so that the section 58 can be rotated about the axis R. the Section 58 also has a slot 60 that is designed to accommodate the protrusion 62 connected to the transverse thrust 44, and turning plot 58 about the axis R of the protrusion 62 is moved in the slot 60. The interaction of p is oresi 60 and lip 62 leads to the displacement of the lateral thrust 44 relative to the frame 34 by turning plot 58 about the axis R. We can assume that the section 58 and, therefore, the inlet tube 28 forming part of the mechanism 32 controls intended to control the movement of the vacuum cleaner 10 over the floor surface.

As shown in figure 1-5, the inlet tube 28 includes a relatively flexible inlet section and a relatively rigid discharge section to which is attached a plot 58. The inlet section inlet tube 28 includes a flexible hose 64, one end of which is connected to an outlet section of the inlet tube 28 and the other end of which is connected to the connecting device 66, intended for connection with a device that consists of a rod and a hose (not shown) and which is designed to move the contaminated air stream in the inlet tube 28. A device consisting of a rod and hose, connected to the cleaning nozzle (not shown)having a hole for suction, through which the flow of polluted air is sucked into the vacuum cleaner 10. The hose 64 is not shown in Fig.6-10 only in order not to overload these figures parts. The mechanism 32 of the control contains the bracket 68, which is designed to support the hose 64 and the connecting device 66 for mounting the connecting device 66 to the frame 34. The bracket 68 includes a front section, protruding forward from the front of the frame 34, and the rear section, which is located between the bottom clubs is th frame 46 and the upper section 48 of the frame. The rear section of the bracket 68 is connected to the frame 34 to ensure the possibility of rotation about the Y-axis rotation bracket. The Y-axis is located at some distance from the P-axis and essentially parallel to the axis R. the Shape of the frame 34 is such that there is a hole 70 through which the bracket 68 protrudes from the frame 34 and which limits the rotation of the bracket 68 with respect to the frame 34 in the range of 65. The bracket 68 includes interacting with the floor rotating element 72, which is designed to support bracket 68 on a floor surface and a rotation axis which is essentially perpendicular to the y-axis.

The vacuum cleaner 10 comprises a support 74 on which a removable manner set separating device 12. Bearing 74 is connected to an outlet section of the inlet tube 28, which is necessary for moving support 74 with the outlet section of the inlet tube 28 during rotation of section 58 about the axis R. As shown at 6, 9 and 11, in this example, the support 74 includes a sleeve 76 which surrounds the inclined section 78 of the outlet section of the inlet tube 28, and includes a platform 80, which departs from the sleeve 76 forward, generally horizontal. Platform 80 includes a curved rear wall 82, which is connected with the sleeve 76 and the radius of curvature of which essentially coincides with the radius of curvature of the outer wall 16 of the outer tank 14 separating device 12, that pic is of bstweet the location of the separating device 12 on a support 74. Centering protrusion 84 moves upward from the platform 80 and is located in the recess 86, made in the base 18 of the outer tank 14.

Preferably bearing 74 was biased upwards to the separating device 12 has been biased toward an outlet pipe 30 of the vacuum cleaner 10. It helps to maintain an airtight seal between the separating device 12 and the exhaust pipe 30. For example, in a cavity made in the rear part of the inlet tube 28 is elastic element 88, which is preferably in the form of a helical spring and which is intended for engagement with a support 74 with the aim of pushing the bearing 74 upward direction, which is preferably essentially parallel to the longitudinal axis of the outer tank 14 when the separating device 12 mounted on a support 74.

When the separating device 12 mounted on a support 74, the longitudinal axis of the outer tank 14 is inclined relative to the axis P, and in this example, the tilt angle is in the range from 30 to 40. Therefore, the rotation of the inlet tube 28 about the axis R during cleaning operations leads to a rotation of the separating device 12 with respect to axis P relative to the frame 34, a rolling device 20 and an outlet pipe 30.

Inclined section 78 of the inlet tube 28 is located along the outer wall 16 of the outer tank 14 is deletelog device 12, essentially parallel to the longitudinal axis of the outer tank 14 when the separating device 12 mounted on a support 74. Preferably, the section 58 was connected with the rear part of the inclined section 78 of the inlet tube 28. The outlet section of the inlet tube 28 also includes a horizontal section 90 below the platform 80 and designed to receive the flow of contaminated air from the hose 64 and the flow of air to the inclined section 78. The outlet section of the inlet tube 28 also has an outlet 92 from which a stream of contaminated air enters the separating device 12.

To move the vacuum cleaner 10 over the floor surface, the user pulls the hose device consisting of a rod and hose, and connected to the connecting device 66, and thereby the user pulls the vacuum cleaner 10 over the floor surface, while rotating the wheels 24, 26 of the rolling device 20, the wheel 40 and the rotating element 72 and the vacuum cleaner 10 is moved on a floor surface. As shown in Fig.7-9, for the direction of the vacuum cleaner 10, for example, to the left when it is moving on a floor surface, the user pulls the hose device consisting of a rod and hose, to the left, so that the connecting device 66 and is attached to the bracket 68 are rotated to the left relative to the y axis, This rotation of the bracket 68 on the Y-axis of prevadid bending of the hose 64 and the application of force to the horizontal section 90 of the outlet section of the inlet tube 28. This effort leads to a rotation of the inclined section 78 and attached thereto section 58 to the left about the axis R. As shown in Fig.9, thanks to the flexibility of the hose 64, the amount by which the bracket 68 is rotated about the Y-axis, greater than the rotation of the inlet tube 28 about the axis R. for Example, when the bracket 68 is rotated around the Y axis by an angle equal to 65, the inlet tube 28 is rotated about the axis P by an angle equal to 25. When turning plot 58 about the axis R, the protrusion 62, which is connected with the transverse thrust 44, moves together with the slot 60 of section 58 (being in it), resulting in transverse rod 44 is moved relative to the frame 34. As shown in Fig and 9, the movement of the lateral thrust 44 causes rotation of each lever 42 of the control relative to the corresponding axis H, so that the wheels 40 are rotated to the left, thereby changing the direction in which the vacuum cleaner 10 is moved on a floor surface. It is preferable that the control mechanism was designed so that movement of the lateral thrust 44 relative to the frame 34 is caused to rotate each wheel 40 on the corresponding different value with respect to the frame 34.

Next, with reference to Fig.6, 12-14 and 16-18 will be described separating device 12. Specific General form of the separating device 12 may be different according to the t-type vacuum cleaner, uses the separating device 12. For example, the total length of the separating device 12 may be greater or less than the diameter of the device or may change the shape of the base 18.

As mentioned above, the separating device 12 includes an external tank 14 containing an outer wall 16, which, essentially, is cylindrical. The lower end of the outer tank 14 is closed by a curved base 18, which can be rotated attached to the outer wall 16 by means of the hinge 94 and is held in closed position by means of latch 96, which communicates with the edge 98 located on the outer wall 16. In the closed position, the base 18 is sealed relative to the lower end of the outer wall 16. The latch 96 is elastically deformed, so that in the case of an application to the upper part of the latch 96 pressure downward, the latch 96 will depart from the edges 98 and detach from it. In this case, the base 18 will depart from the outer wall 16.

As shown in Fig (b), the separating device further comprises a second cylindrical wall 100. The second cylindrical wall 100 is located radially inward relative to the outer wall 16 at some distance from it, so that between them is formed the annular chamber 102. The second cylindrical wall 100 reaches the base 18 when the base 18 is away in the closed position and sealed relative to the base 18. The annular chamber 102 is limited, in General, the outer wall 16, the second cylindrical wall 100, the base 18 and the top wall 104, located on the upper end of the outer tank 14.

The inlet 106 to the polluted air is located on the upper end of the outer tank 14, the top wall 104 and is designed to receive air flow from the outlet 92 of the inlet tube 28. The inlet 106 to the polluted air is tangentially relative to the outer Baku 14 (as shown in Fig.6)to the incoming polluted air followed a spiral path along the annular chamber 102. The inlet opening 106 for air pollution takes a stream of air from the pipe 108 connected with the outer wall 16 of the outer tank 14, for example, by welding. The channel 108 has an inlet 110, the size of which essentially coincides with the size of the outlet 92 of the inlet tube 28 and which is located over the outlet 92, when the separating device 12 mounted on a support 74.

In the external tank 14 provides a release for the fluid, which has the form of a casing. The casing includes an upper portion 112, made in the form of a truncated cone, the lower cylindrical part 114 and below the portion 116, is made in the form of the apron. Made in the form of the apron portion 116 russiae the camping out from the bottom of cylindrical wall 114 toward the outer wall 16. In the upper part 112 of the casing and the cylindrical wall 114 of the housing are made with a number of holes. The only issue for the fluid from the external tank 14 are openings in the casing. Between the casing and the second cylindrical wall 100 is made passage 118. The passage 118 communicates with the chamber 120 high pressure. The camera 120 high pressure is located radially outward from the casing and located above the upper part 112 of the casing.

Third, in General, cylindrical wall 122 moves away from the place next to the base 18, reaches the outer walls of the chamber 120 high pressure and forms a generally cylindrical chamber 124. The lower end of the cylindrical chamber 124 is closed by end wall 126. Form a cylindrical chamber 124 is such that it can accommodate the removable filter 128 in the collection containing the bypass pipe 130 in the collection, which will be described in detail below. The filter 128 Assembly removable manner is installed in the cylindrical chamber 124 so that when using the vacuum cleaner 10 no mutual rotation between the filter 128 in the collection and the remaining part of the separation device 12. For example, the separating device 12 may be equipped with one or more slots, which when inserted into a filter 128 in the collection in the separating device 12 are projections made on the filter 128 in the collection.

On a circle around the camera 120 value what about the pressure there are several cyclones 132, placed parallel to each other. As shown in Fig (a) and 14 (b), each cyclone 132 contains tangentially located inlet opening 134, which communicates with the chamber 120 high blood pressure. All cyclones 132 are the same and each cyclone 132 has a cylindrical upper portion 136 and below the tapered portion 138. Tapered portion 138 of each of the cyclone 132 has a shape of a truncated cone and ends with a solution of cone. The cyclone 132 is directed into the annular region 140 (and reported it), which is formed between the second and third cylindrical walls 100, 122. The discharge nozzle 142 is located on the upper end of each cyclone 132, to allow air to exit the cyclone 132. Each discharge nozzle 142 is in communication with the tube 144 collector located above the cyclone 132. In a preferred embodiment, the invention provides twelve cyclones 132 and twelve tubes 144 collector. Twelve cyclones 132 are ring, the center of which lies on the longitudinal axis X of the outer tank 14. Each cyclone 132 has an axis that is tilted down towards the x-axis All axes With tilted at the same angle relative to the axis X. we Can assume that twelve cyclones 132 form a second cyclonic separating unit, while the annular chamber 102 forms a first cyclonic separating unit.

In the second cyclonic separating unit, the diameter of each of the cyclone 132 is less than the diameter of the annular chamber 102, and, thus, the second cyclonic separating unit is able to separate smaller particles of dirt and dust compared to the first cyclonic separating unit. It also has the additional advantage that it passes through the air, already cleared the first cyclonic separating unit, and accordingly the quantity of dust particles and their average size is smaller compared with the case of absence of the first cyclonic separating unit. The separation efficiency of the secondary cyclone separation unit higher than the efficiency of separation of the first cyclonic separating unit.

Each tube 144 collector, in General, is U-shaped and limited by the upper wall 146 and the bottom wall 148 of the collector 150 of the second cyclonic separating unit. Tube 144 collector departs from the upper end of each cyclone 132 and reaches the overflow tube 130 in the collection.

As shown in Fig (C), the bypass tube Assembly 130 includes an annular seal 152 and the bypass tube 154. Removable filter 128 Assembly is located below the bypass tube 154 in the cylindrical chamber 124. In a preferred embodiment of the invention, the seal 152 is made of rubber and is fixed around the outer surface of the overflow tube 154 through a friction fit. The bypass tube 154 includes upper part and lower part. The seal 152 is located on the top of the overflow tube 154. The upper part of the overflow tube 154 contains a generally Cup-shaped portion 156, which provides an outlet for the fluid from the separating device 12 and the shape of the outer surface of which is convex, preferably spherical curvature. The lower part of the overflow tube 154 includes a flange 158 and the cylindrical outer casing 160, the form of which is to match the size and shape of the cylindrical chamber 124. Form edge 158 is such that its diameter was slightly larger than the diameter of the cylindrical outer casing 160 and flange 158 is directed to the upper end of the cylindrical outer casing 160. Intake chamber 162 is located between the upper and lower parts of the bypass tube 154. Intake chamber 162 is limited by the lower surface of the Cup-shaped portion 156, the top surface of the cylindrical outer casing 160 and the flange 158. As shown in Fig (b), the outlet of each tube 144 collector ends in the inlet chamber 162 of the overflow tube 130 in the collection.

The bypass tube 154 contains the first set of tubes in which air passes in the first direction through the bypass tube 154, and a second set of tubes in which air passes in the second direction through the PE auckney tube 154, moreover, the second direction different from the first. In this embodiment of the invention in a cylindrical outer casing 160 of the overflow tube 154 is located eight tubes. These tubes contain the first set of four inlet tubes 164 of the filter and a second set of four exhaust pipes 166 of the filter. The inlet tube 164 of the filter are koltseobrazno with center on the X-axis, and the inlet tube 164 of the filter are located at equal distances from each other. The discharge tube 166 filter similarly situated at equal distances from each other around the axis X, but they are located between the inlet tube 164 of the filter, preferably offset from the inlet tube 164 of the filter at an angle of approximately 45.

Each inlet tube 164 of the filter has an inlet opening directed toward the top surface of the cylindrical outer casing 160 and adjacent to the inlet chamber 162, and an outlet opening directed towards the base of the cylindrical outer casing 160. Each inlet tube 164 of the filter has a passage located between the inlet and outlet ports. The cross-section of the passage is gradually changed in order to reduce noise and turbulence of the air flow passing through the bypass tube 154.

Each discharge tube 166 of the filter has an inlet opening 168, executed in the external surface is the cylindrical surface of the outer casing 160, and the outlet 170, designed for directing filtered air from the filter 128 in the Assembly toward the outlet pipe 30. Thus, each discharge tube 166 has a passage that is located between the inlet 168 and the outlet 170 and which passes through a cylindrical outer casing 160 from the outer surface of the cylindrical outer casing 160 in the direction of axis X. Therefore, the outlet 170 is closer to the X-axis than the outer hole 168. Preferably, the outlet 170 was all.

Cup-shaped portion 156 of the overflow tube 154 includes a holder 172, which you can grab and which is designed to enable the user to pull the filter 128 in the collection of the separating device 12 for cleaning. Holder 172 protrudes up from the base of the Cup-shaped portion 156 along the X-axis so that it protrudes from the second cyclonic separating unit. The bypass tube 154 also includes a number of side pads 173, which are arranged so as to deviate downward from the bottom surface of the Cup-shaped portion 156, and which are intended to support the upper part of the overflow tube 154 on the bottom.

As shown in Fig (b), and Fig and 16, the filter 128 in the collection contains the top edge 174, the base 176 and four cylindrical filtering elements is a, located between the edge 174 and the base 176. In General, the filter 128 Assembly has a cylindrical shape and has an internal chamber 178, limited edge 174, a base 176 and located most closely to the center of the first filter element 180 filter 128 in the collection. Flange 174 is held in the annular groove, located in the lower part of the overflow tube 154.

The filter 128 in the collection are made so that it is flexible and elastic. Flange 174 is annular and its width in the direction perpendicular to the X-axis equal to W. the Flange 174 is made of a material of such hardness and deformability, which allow the user to deform the edge 174 (and thus the filter 128 in the collection), manually pressing or gripping edge 174 and twisting and squeezing the filter 128 in the collection, in particular during the operation of washing. In this embodiment of the invention, the flange 174 and the base 176 is made of polyurethane.

Each filtering element 128 Assembly is rectangular. Thus, the four filters are combined together along their longest edges by stitching, gluing or other suitable way, to get a piece of the filter material in the form of a tube, essentially cylindrical shape with an open end, the height of the tube in the direction of the X axis is equal to N. The upper end of each of the th cylindrical element attached to the flange 174, and the lower end of each filter element connected to the base 176, preferably by casting on top of the polyurethane material edges 174 and the base 176 in the manufacture of filter 128 in the collection. Alternative methods of mounting the filter elements are bonding and centrifugal casting of polyurethane around the upper and lower ends of the filter elements. Thus, the filter elements into the polyurethane during manufacturing that is done in order to obtain enhanced design, capable of withstanding manipulation of the user, particularly during washing of the filter 128 in the collection.

The first filter element 180 includes a layer of mesh material with an open woven or mesh structure. The second filter element 182 surrounds the first filter element 180 and made of non-woven filter material, such as fleece. The shape and volume of the second filter element 182 is selected so that, in essence, to fill the volume limited by the width W of the flange 174 and the height H of the filter 128 Assembly, measured along the axis X. Therefore, the width of the second filter element 182 is essentially the same as the width W of the flange 174.

The third filter element 184 surrounds the second filter element 182 and contains electrostatic filter material, closed on both sides of the protective cloth. Layers at rivalda together known in the art, using stitching or other airtight manner. The fourth filter element 186 surrounds the third filter element 184 and includes a layer of mesh material with an open woven or mesh structure.

During manufacture, the upper portion of the first filter element 180 is attached to the flange 174 and the base 176 directly next to the second filter element 182. The upper part of the third filter element 184 is attached to the flange 174 and the base 176 directly next to the second filter element 182 and the upper part of the fourth filter element 186 is attached to the flange 174 and the base 176 directly next to the third filter element 184. Thus, the filter elements 180, 182, 184, 186 are held in place in the filter 128 Assembly relative to the edges 174 and the base 176, so that the air stream enters first through the first filter element before proceeding, in turn, second, third and fourth filter elements. Regarding the third filter element 184 containing electrostatic filter material, coated on both sides with a protective cloth, preferably, all the layers of the third filter element 184 are attached to the edge 174 and the base 176, so that when used to reduce the risk of peeling of the second filter element 184.

Next, with reference to Fig.6, 21 (a) and 21(b) will be described exhaust TRU is 30 ka. Discharge tube 30 is, in General, curved sleeve connecting the separating device 12 and a rolling device 20. Discharge tube 30 has an inlet for the fluid medium having the form of a ball joint 188 with an external convex surface, and an elongated tube 190 that is designed to receive air from the ball joint 188. Elongated tube 190 provides the passage 192, designed to move air from the separating device 12 in a rolling device 20. As shown in Fig.6, the axis R of rotation passes through the discharge tube 30, preferably through a ball joint 188 discharge tube 30.

Ball joint 188 is, in General, a hemispherical shape and it is located in the removable Cup-shaped portion 156 of the overflow tube 154, which is visible through the open upper end of the collector 150. Thus, the separation between the device 12 and outlet tube 30 is formed of a ball swivel. Ball joint 188 includes a flexible annular seal 194 surrounding ball joint 188, while the annular seal 194 contains an edge 196, designed to interact with the inner surface of the Cup-shaped portion 156 of the overflow tube 154. This provides an effective and reliable seal between the ball connection 188 and by-pass tube 154. In it is the quality alternative to the external surface of the ball joint 188 may contain such elements, as directed outward protrusion, the flange or rib, which interact with the Cup-shaped part 156 bypass tube 154. In addition, in the preferred embodiment of the invention, the seal 152 bypass tube Assembly 130 is flexible and has such a shape that the diameter of the upper part of the seal 152 is slightly less than the diameter of the ball joint 188, which is necessary to obtain a tight elastic connections around the outer surface of the ball joint 188. The seal 152 can also seal any gaps between the ball connection 188 and the second cyclonic separating unit.

As described previously, rotation of the inlet tube 28 about the axis R during cleanup operations leads to a rotation of the separating device 12 about the axis P with respect to the exhaust tube 30. As shown in Fig.6, the seal 196 and fit the upper edge of the seal 152 to ball connection 188 contributes to the ongoing communication between the (stationary) passage 192 of the discharge tube, and (movable) outlet holes 170 bypass tube 154. Therefore, when moving the separating device 12 relative to the discharge tube 30 during movement of the vacuum cleaner 10 over the floor surface between the separating device 12 and outlet tube 30 is maintained airtight connection is used.

Next, with reference to Fig and 23 will be described rolling device 20. A rolling device 20 includes a main portion 22 and two bent wheels 24, 26 that are rotatably attached to the main part 22 and which interact with the floor surface. In this embodiment of the invention the main part 22 and wheels 24, 26 define essentially spherical rolling device 20. The axis of rotation of the wheels 24, 26 is tilted up towards the main part 22 relative to the floor surface on which is located the vacuum cleaner 10 so that the edges of the wheels 24, 26 communicate with the floor surface. Preferably, the angle of the axes of rotation of the wheels 24, 26 ranged from 5 to 15, more preferably from 6 to 10, and in this embodiment of the invention, this angle is approximately 8. Each wheel 24, 26 of the rolling device 20 is dome-shaped, and the outer surface, essentially, has a spherical curvature, so that the shape of each of the wheels 24, 26 are, in General, is hemispherical. In a preferred embodiment of the invention the diameter of the outer surface of each of the wheels 24, 26 is less than the diameter of the rolling device 20 and is preferably from 80 to 90% of the diameter of the rolling device 20.

A rolling device 20 contains driven by the motor fan unit 200, the device the wire, designed for retracting and storing in the main part 22 of the part of the electric wires (not shown), ending with a fork 203 and the supply of electric energy, among other things, the motor fan unit 200 and the filter Assembly 204. The fan unit 200 contains the motor and the impeller, which is driven by the engine in order to suction in the vacuum cleaner 10 (and pass through) flow of polluted air. The fan unit 200 is located in the duct 206 of the engine. Box 206 engine is connected with the main part 22, so that the fan unit 200 does not rotate when you move the vacuum cleaner 10 over the floor surface. The filter Assembly 204 is located downstream relative to the fan unit 200. The filter Assembly 204 is shaped cuff and is located around a portion of the duct 206 of the engine. In box 206 of the engine, which is surrounded by a filter 204 in the collection, made many holes 207.

The seal 208 separates the device 202 winder wire from box 206 engine. The seal 208 facilitates the separation of the main part 22 in the first area, which contains the fan unit 200 that generates heat during use, and a second area containing the device 202 winder wire, for which heat is harmful and for which you may require cooling.

The filter Assembly 204 may periodically the understanding with the rolling device 20, in order to allow cleaning of the filter Assembly 204. Access to the filter Assembly 204 can be obtained if remove the wheel 26 of the rolling device 20. This wheel 26 can be removed, for example, if the user would first Unscrew the end cap 210, mounted on the wheel 26, to remove the landing ring 212 of the wheel located at the end of the axis 214, which is connected to the frame 206 of the engine. The seat ring 212 wheels may be located between the axis 214 and system 216 of wheel bearing. Further, the user can pull the wheel 26 with the axis 214, so that the seat ring 212 wheel system 216 of wheel bearing and end cap 210 is removed from the axis 214 together with the wheel 26. Further, the filter Assembly 204 can be removed from the rolling device 20 by pressing on the latch 218 connecting the filter Assembly 204 to the frame 206 of the engine, and pull the filter Assembly 204 of the rolling device 20.

The main part 22 of the rolling device 20 additionally has an inlet 220 to the fluid, the annular chamber 222, which is designed to receive air from the inlet holes 220, and the passage 224, limited by the camera 222. The form of the camera 222 is to gradually change the cross-sectional area for flow of air passing from the inlet 220 to the fan unit 200. The camera 222 provides the direction change passage 224 is approximately 90 Smooth path and a smooth change in cross-sectional area of the passage for the flow of air can reduce inefficiencies in the system, for example losses through the duct 206 of the engine. Between the inlet 220 and the chamber 222 of the engine can be located grille, designed to protect the fan unit 200 and box 206 engine from objects that otherwise can hit, block, and/or to occlude the camera 222 of the engine, for example, when removing the separating device 12 of the main part 22 that will be described below.

The fan unit 200 contains a set of exhaust pipes 230, located around the outside border of the fan unit 200. In a preferred embodiment of the invention around the fan unit 200 has four discharge tube 230, which provide the message of the fan unit 200 and box 206 engine. The filter Assembly 204 is located around boxes 206 engine and holes 218 facilitate message box 206 of the engine and the main portion 22. The main part 22 further comprises an exhaust channel for air, intended for production of purified air from the vacuum cleaner 10. The exhaust channel is directed toward the rear of the main part 22. In a preferred embodiment of the invention the outlet channel has several outlet openings 232, located in the lower part of the main part 22 so as to create minimal turbulence in the environment outside of the vacuum cleaner 10.

The first dirigible is a user switch 234 is located on the main part of the case, so when it is pressed, the fan unit 200 is operated. Also when you click on the first switch 234 of the fan unit 200 may be turned off. The second user controlled switch 236 is located next to the first switch 234. The second switch 236 allows the user to operate the device 202 winder wire. Electric circuit 238, intended for the actuation of the fan unit 200 and the device 202 winder wire, is also located in the rolling device 20.

The main part 22 contains a bypass valve 240 that is designed to allow air flow to move the fan unit 200 in the case of blocking, taking place, for example, in a device consisting of a rod and hose. This prevents overheating or other damage to the fan unit 200. The bypass valve 240 includes piston chamber 242 in which is located the piston 244. At one end of the piston chamber 242 is executed hole 246 intended for messages piston chamber 242 with the external environment through the outlet opening 232 and at the other end of the piston chamber 242 formed channel 248 intended message piston chamber 242 with the passage 224.

Coil spring 250 compression ratio, which is located in the piston chamber 242, pushes the piston 244 in the direction of colizeo the different seat 252, inserted into the piston chamber 242 through the opening 246. When using the vacuum cleaner 10, the force F1acting on the piston 242 and the opposing bias force F2the springs 250, due to the differential pressure of air acting on each side of the piston 244, less bias force F2springs 250 and, thus, the hole 246 is closed. In the case of blocking the flow path of the air upstream relative to the channel 248, the difference in pressure acting on opposite sides of the piston 242, will increase significantly. Bias force F2spring 250 is selected such that in this case the force F1there will be more forces F2, resulting in the piston 244 moves from seat 252 and opens the hole 246. It will allow air to pass from the external environment through the piston chamber 242 and get into the passage 224.

When using the user activates the fan unit 200, for example, by clicking on the switch 234, and the flow of polluted air is sucked into the vacuum cleaner 10 through the opening for suction, located in the cleaning nozzle. The flow of contaminated air passes through the device, consisting of a rod and hose, and enters into the inlet tube 28. The flow of contaminated air passes through the inlet tube 28 and into the inlet 106 for zagryaznennosti separating device 12. Due to the tangential arrangement of the inlet 106 to the polluted air, the air flows along a helical path along the outer wall 16. Due to the centrifugal force large particles of dirt and dust are deposited in the annular chamber 102 and accumulate there.

Partially purified stream of air emerges from the annular chamber 102 through the openings in the casing and into the passage 118. Next, the air flows into the chamber 120 high pressure and from there falls into one of the twelve cyclones 132 through inlet 134, thus more cyclone separation is the separation of some part of the dirt and dust contained in the air stream. This dirt and dust accumulates in the annular region 140, and the cleaned air leaves the cyclone 132 through the discharge nozzle 142 and into the tube 144 collector. Then the air flows in the bypass tube 154 through the inlet chamber 162 and into four inlet tube 164 filter bypass tube 154. Of the four inlet tubes 164 of the filter, the air flow enters the Central open chamber 178 of the filter 128 in the collection.

The air flow passes through the Central open chamber 178 and is directed tangentially outward to the filtering elements of the filter 128 in the collection. The air flow goes first in the first filtering the element is provided 180, next, pass through the second filter element 182, the third filter element 184 and the fourth filter element 186, and when the passage of air flow through each filter element from the stream are extracted dirt and dust.

The flow of air released from the filter 128 Assembly, passes into the cylindrical chamber 124 and is sucked into the exhaust pipe 166 filter bypass tube 154. The air flow passes through the outlet tube 166 of the filter and exits the bypass tube 154 through four outlet openings 190 in the Cup-shaped portion 156 of the overflow tube 154. The air flow enters the ball joint 188 discharge tube 30 extends along the passage 192 and gets into the main part 22 of the rolling device 20 through the inlet 220 to the fluid.

In the rolling device 20, the flow of air sequentially passes through the grid and the passage 224 and enters the chamber 222. The camera 222 directs the air flow in the fan unit 200. The seal 208 prevents the passage of air flow through the device 202 winder wire. The air flow exits the outlet tube 230 of the engine in the frame 206 of the engine. Next, the air flows box 206 engine in the tangential direction through the openings 218 and passes through the filter Assembly 204. Finally the flow of air, following the curvature of the main part 22, enters the exhaust is TVersity 232 of the main part 22, where the stream of purified air is expelled from the vacuum cleaner 10.

Discharge tube 30 removable way connected to the separating device 12 that is necessary to ensure the possibility of extracting the separating device 12 of the vacuum cleaner 10.
