Cyclone tank 11 may be made in the form of a cylinder that is located, for example, horizontally, and the outlet 20 may be made from one side of the cyclone vessel 11. The exhaust pipe 13 may be of the outlet 20 and pass into the cyclone chamber 22 and the grating element 18 can be attached to one end of an exhaust pipe 13. The outlet 16 to dust may, for example, have approximately a square shape in the circumferential direction of cyclone tank 11.

The tank 30 to dust may contain the first reservoir 32, the second tank 34 and the bottom plate 31, which form a space 36 for collecting dust inside of the tank.

The first and second reservoirs 32, 34 can be a bottomless cylinders, of which the first reservoir 32 may be attached to the cyclone tank 11, and the second tank can be made so that he ohvatyvaet the first tank 32 on the outer perimeter. The bottom plate 31 may be a circular plate, which opens or closing the AET bottom surface of the second tank 34 and one end may be connected to rotate with the side of the lower part of the second tank 34, and the other end may be fixed in useplease element 48 made on the other side of the second tank 34. With reference to Figure 4 it is seen that the bottom plate 31 can be selectively opened in order to ensure removal of dust from the space 36 to collect dust, if useplease element 48 on the side of the second tank 34 is pressed in the direction indicated by arrow 'A'. If pilotless device 9 is installed in the main body 90 of the vacuum cleaner, as shown in figures 1 and 2, the second tank 34 and the bottom plate 31 may be maintained in contact with the main body 90 of the vacuum cleaner.

As shown in Fig.2-4, the device 70 to transmit the drive force may contain screw pin 78, the screw element 32, the connecting member 74 and the first and second clutches 76, 77. Screw pin 78 may be designed as a cylindrical pin, for example, threaded on its inner surface. The upper end of the pin 78 can be attached to the outer circumference of the cyclone vessel 11. Screw element can also contain a thread made on the outer periphery and inserted in the screw pin 78 for coupling threaded on its inner circumference. The connecting member 74 may be made with the possibility of rotation on the bottom plate 31 to rotate in the clutch with the shaft 54 of the motor or separately from the shaft 54 in accordance with the installation of leudelange device main body 90 of the vacuum cleaner or removing from it. The first and second clutches 76, 77 can be made between the screw element 72 and the connecting element 74. In other words, the first clutch 76 may be connected with the connecting element 74 and second clutch 77 may be connected with a screw element 72. If the bottom plate 31 is open, the first clutch can be separated from the second coupling 77, leaving the second clutch 77 together with a screw element 72 is suspended on threaded pin 78.

Figure 1 and 2 shows that the drive motor 52 may be performed in the chamber 50 to a drive motor, which may be provided in the main body 90 of the vacuum cleaner under pilotgeek device 9. Item 59 connection axes, which may be linked in coupling with a connecting element 74 of the device 70 may be connected with the shaft 54 of the motor. Accordingly, the drive force of the engine can be transmitted to the connecting element 74 through the shaft 54 and the element 59.

Figure 3 and 4 shows that the output channel 60 and the input channel 65 can be performed vertically and in parallel relation to each other. Although figure 2 shows only the output channel 60, figure 3 shows that the input channel 65 can be made adjacent to the outlet channel 60. Output channel 60 and the input channel 65 can contain respectively an outer tube 62 and outer tube 66. In addition, the output channel 60 and the input channel 65 can content shall be, respectively, the inner tube 64 and the inner tube 67. The outer tube 62 of the outlet channel 60 can be attached to the cyclone tank 11 with ensuring the flow of messages with the passage 64 to the fluid, which may be made in the shape of a square and can be connected to the output 20, which is made on the side of the cyclone vessel 11. The outer tube 66 of the input channel 65 may be attached to the cyclone tank 11 with ensuring the flow of message input (not shown), which can be performed in a direction tangentially to the cyclone tank 11. Figure 3 shows that each of the inner tubes 64, 67 output channel 60 and the input channel 65 can be attached to the bottom plate 31. Accordingly, the outer tube 62, 66, and cyclone tank 11 and the first reservoir 32 is arranged to move relative to the second tank 34 and the bottom plate 31. As an example, the inner tubes 64, 67 can be inserted respectively into the outer tube 62, 66, if the tank 30 is retracted, while the inner tube 64, 67 can be down if the tank 30 is advanced. The total length of the outlet channel 60 and the input channel 65 can be increased or reduced by the length of the extending or retracting of the tank 30.

Although they are not shown in the main body 90 of the vacuum cleaner can be provided by the electric current sensor and control device. Sensor electronic the historical current can measure in real time the amount of electric current, supplied to the drive motor 52 for detection of overload. The control device may control the operation of the motor 52.

Work pyleudalyayuschemu device 9 will be explained below with reference to Figures 1-4.

When the vacuum cleaner starts working, the air stream may be drawn through the brush unit (not shown) and the input channel 65 pyleudalyayuschemu device 9. Air flow can rotate when it enters the cyclone tank 11 through the inlet of cyclone separator 10. Dust particles with a strong centrifugal force can be separated from the rotating air stream and fall into the space 36 to collect dust through the outlet 16 to dust. Purified air stream can then be released through the grating element 18 and the outlet 20. After the airflow emitted through the output channel 60 and the lower part of the bottom plate 31, it can be released through the device to create a vacuum (not shown).

The cyclone separator 10 may be positioned horizontally, the axis of rotation may be horizontal, while the separator 10 can flow to communicate with the space 36 dust only through the outlet 16 to dust. Accordingly, unlike the vertical cyclone design, in which there is no distinction between the cyclone chamber 22 and the space 36 for collecting dust, maybe PR is tetramino or restricted flow in the opposite direction of the dust from the space 36 of the separator 10 through the rotating air flow cyclone chamber 22.

The user of the vacuum cleaner may be able to adjust the capacity, or volume, of the tank 30 for dust in accordance with the terms of the cleared space. More specifically, the user can increase or decrease capacity before or during operation of the vacuum cleaner without removing and not even touching paleodelta device 9.

If the user wants to increase the capacity of the tank 30 for cleaning extremely dusty area or a large area such as a store, factory, etc., the user can rotate the drive motor 52 in the forward direction. When the drive motor 52 is open, the element 59 connection axis and the connecting element 74 attached to the motor 52 can rotate, it also can rotate and screw element 72 connected through the first and second clutches 76, 77. Since the drive motor 52 rotates in the forward direction, the screw element 72 can rotate in the forward direction, and the screw pin 78, is screwed to a screw element 72 may be moved to the upper side of the second tank 34, pushing the first reservoir 32 and the cyclone separator 10 in the upward direction. With reference to Figure 4 it is seen that if the screw pin 78 is moved to the position in which the space 36 has a maximum capacity, cyclone separator 10 and the first reservoir 32 may not move Yes the more. As a result, the electric current supplied to the motor 52 increases. The electric current sensor detects this increase and reports overload the motor 52 of the control device. In the control device stops the supply of electricity to the motor 52, the motor 52 stops the operation.

If the user needs to clean the area where dust is relatively smaller, such as, for example, room or office, the user can reduce the capacity of the space 36 by bringing the motor 52 to move in the backward direction. When the drive motor rotates backward, the screw element 72 can rotate ago, and, accordingly, the screw pin 78 connected to the screw element 72 may also be moved down relative to the screw element 72. In the cyclone separator 10 of the first reservoir 32 that is connected with a screw pin 78 may be moved down relative to the second tank 34, reducing the space 36. When the motor 52 is rotated in the forward direction, so that the space for collecting dust reaches maximum capacity, the motor 52 is overloaded, if the space dust is reduced to the minimum capacity (Figure 2). In addition to the actuation of the motor 52 to such an extent that a space 36 for dust collection is the best is there a minimum capacity the user can also terminate the operation of the drive motor 36 when the space 36 dust reaches a predetermined height. For actuation of the motor 52 in the forward and backward directions and for controlling the motor 52 can be applied traditional techniques. Therefore a detailed explanation of these methods will be omitted for brevity.

Figure 5-7 depicts illustrative pilotless device 119 in accordance with the second illustrative option execution.

Pilotless device in accordance with another illustrative variation of execution may include a cyclone separator 110, the reservoir 130 to dust, the device 170 of the transmission of the drive force transmission device, which can include the drive motor 150, the output channel 160 and the input channel (not shown).

Cyclone separator 110, a reservoir for dust 130 containing the first and second tanks 132, 134, the output channels 160 and the input channel containing the inner and outer tubes 162, 164 may have a construction similar to or similar to the design described above in the first illustrative embodiment. Accordingly, the following describes only the location of the engine 150 and the device 170 of the transmission of the drive force.

Compared with the first illustrative option run the drive motor 150 may be you who olden in the main body 190 cleaner side pyleudalyayuschemu device 119 (Figure 5 and 6). The engine 150 can be positioned horizontally, and the gear shaft 156 can be made at the end of the motor shaft (not shown). Gear 156 may be in the receiving chamber for dust collection of a vacuum cleaner (Fig.7).

Figure 7 shows that the device 170 may include a rail 172 and the gear 178. The rail 172 can be performed vertically on the outer periphery of the first reservoir 132 and the gear 178, which may be on the thread attached to the rail 172 may pass through the second reservoir 134. One side of the gear 178 may be attached to the rail 172 and the other side can be connected with the gear shaft 156 of the engine 150.

Similar to the first illustrative option run one end of the bottom plate 131 may be fixed to rotate to the second reservoir 134 and the other end may be clicks into place with useplease element 148 (6).

Adjustable work tank for dust pyleudalyayuschemu device 119 in accordance with the second illustrative option execute explained below, focusing mainly on differences from the first illustrative scenarios.

If the user rotates the drive motor 150 in the forward direction, the gear 156 of the shaft of a drive motor 150 can rotate, and the gear 178 is connected with the gear 156 of the shaft can rotate with provision re is edenia Reiki 172 up. Because the rail 172 can be attached to the first reservoir 132, the first tank 132 can be moved in an upward direction relative to the second reservoir 134 and attached cyclone separator 110 may also be moved in the upward direction. Similar to the first illustrative variant of execution of the outer tube 162 of the input channel (Figure 3) and the output channel 160 can be moved upward in accordance with the movement of the first tank 132. If the drive motor 150 rotates in the backward direction, rod 172 can be moved down, and the first tank 132 can move down, reducing the space 136 to collect dust. With reference to Fig.7. it is seen that the space 136 in a state indicated by a double dotted line, is approximately the maximum capacity, while a space 136 in the state indicated by the solid line, is approximately the minimum capacity. The engine 150 can be controlled by measuring the electric current, as described above in the first illustrative embodiment. Room 163 position represents the channel for the fluid, which corresponds to the channel 63 to the fluid of the first illustrative scenarios.

Fig is a view in section pyleudalyayuschemu device 119, optionally containing compressing element 180, made under the cyclone will separate the LEM 110, in accordance with the second illustrative option execution.

In accordance with the second illustrative option run pilotless device 119 may include compressing element 180, made in the tank 130 for dust, designed to compress the collected dust when the space 136 dust is reduced.

Compressing element 180 may be made in the form of a plate having a shape corresponding to the horizontal part, and more specifically to the inner diameter of the first reservoir 132, or in the form of a plate having a protruding down the Central part.

Compressing element 180 may be made separately and attached to the bottom surface of the cyclone separator 110 or made as a single unit with the lower surface of the separator 110. In the latter case, the element 180 can pass radially on the outer circumference of the separator 110.

Compressing element 180 can be performed at a specified distance from the lower surface of the separator 110, and its surface may be fixed in contact with the inner surface of the first reservoir 132 and outer surfaces of the output channel 160 and the input channel (not shown)that pass through the compressing element 180.

As shown above, the compressive element 180 may have different designs and contain exit 186 for dust passing through the surface, the which is addressed to exit 111 for cyclone dust separator 110. The area between exit 186 for dust compressing element and the output 111 for dust can be turned into the passage 182 to dust by the side wall 181, which connects the entire outer circumference of the output 186 to dust compressing element and output 111 to dust.

The passage 182 for dust, which can be formed in side wall 181, separates the region in which the dust is moved between the output 111 cyclone dust separator 110 and exit 186 for dust compression element, thereby preventing the dissipation of the dust separated in the cyclone separator 110, in a different area than the space 136 to collect dust.

Compressing element 180 having the above-described structure, can operate to compress dust in the space 136 by moving in a downward direction together with the separator 110, if the space dust is retracted. Accordingly, pilotless device 119 in accordance with the second illustrative option can further increase the variable capacity space 136.

Compressing element 180 pyleudalyayuschemu device 119 in accordance with the second illustrative option may be adapted equally to paleodelta device 9 of the first illustrative scenarios.

As described above, the user may have possibly the be a certain way to adjust the capacity of the space for collecting dust in accordance with the terms of the cleared space. Accordingly, the level of convenience for the user improves.

In addition, since there is a possibility to adjust the space for collecting dust by using the drive force of the engine, the user does not need to touch paleodelta device or remove it. The user may also be able to conveniently adjust the space for collecting dust, even during operation of the vacuum cleaner.

Further, since dust may be compressed, space dust may have increased storage capacity.

Also, since you can adjust the variable capacity space for collecting dust, without affecting the cyclone separator, the dust separation efficiency can be maintained constant.

In addition, the likelihood that dust from space dust will pass back through the cyclone outlet, may be reduced.

The above-described several illustrative embodiments. However, it should be understood that various modifications are possible. For example, satisfactory results can be achieved if the described techniques are performed in a different order and/or if components in a described system, design, device, or circuit are connected in a different manner and/or replaced or supplemented by other components or their equivalent the AMI.
