On the other hand, each second part 42 for centrifugal separation separates by centrifugal force fine dust containing relatively small particles, such as powder dust, which is the first part 41 for centrifugal separation can not be separated under the action of centrifugal forces, i.e. dust, which is smaller than coarse dust D separated the first part 41 for centrifugal separation. In other words, the flow velocity and the ability of the centrifugal separation of each of the second part 42 for centrifugal separation above sorostitute and the ability of the centrifugal separation of the first part 41 for centrifugal separation. For example, in the embodiment, five of the second parts 42 for centrifugal separation of the front and rear on each side and four parts for centrifugal separation of the front and rear in the Central part, in the amount of 14 second parts for centrifugal separation, and are connected in parallel with the air channel 43.

The upstream side of each rectifier channel 82 is open forward to the upstream side in the air duct 43, and each rectifier channel 82 is gradually tilted toward the downstream side. Thus, each second part 42 for centrifugal separation is performed so that the air containing the dust passing through the air channel 43, is held in the main body 77 of each of the second parts for centrifugal separation in the direction of the tangent through each rectifier channel 82.

In the air duct 43 is made as one air channel 84 on the front side as the air duct on the side put in place the x on the stream, located on the front side that is facing up stream, and is connected with the first part 41 for centrifugal separation, and air channel 85 on the rear side as an air channel on the downstream side, located on the back side that is facing down stream, and is connected with the air channel 84 on the front side and the second parts 42 for centrifugal separation.

Dust collection container 44 can be connected/disconnected with/from each of the second part 42 for centrifugal separation.

The exhaust air channel 45 formed in the longitudinal direction back and forth along the top of each plot of the second part 42 for centrifugal separation, located in the Central part in the horizontal direction of the width. Branched portion 45a of the air channel speakers and branch off from both sides of the exhaust air channel 45, and the portion 45a is communicated with a side downstream of each of the second parts 42 for centrifugal separation, located on the left and right sides, the upper end of the ventilation of the cylindrical part 81.

In the dust collection device 26 is hermetically formed dust-air channel 87 which communicates with the suction inlet 60, the body 51 of the container, prefer inimi holes 65 (dust filters 53), end hole 74 (sealing filter 54), the air channel 43, each rectifier part 78, the main body 77 of each of the second parts for centrifugal separation, each ventilation cylindrical portion 81 and the exhaust air channel 45.

Then, it will be described the operation of a variant of implementation. In addition, to provide clear descriptions of the outer cover 46 is excluded in figure 1.

During the cleaning, as shown in figure 4 and 5, the dust-collecting device 26 is mounted to the housing 25 of the main body 13 of the vacuum cleaner. In this state, the suction hole 60 of the first part 41 for centrifugal separation of dust collection device 26 is hermetically coupled to the connecting air cal 38, the exhaust air channel 45 is hermetically connected with the side of the suction fan 31, and thus, the node 12 of the tube and dust-air channel 87 in the dust collection device 26 is hermetically connected with the side of the suction fan 31.

The user pulls the cord 37 is a power vents cord for connection of the cord 37 power outlet on the wall surface or the like, grasps the handle 21 and actuates the necessary adjusting button 22 so that the control device actuates the fan 31 in the prescribed working R is the bench.

The negative pressure created by the actuation of the electric fan 31 attached to the node 12 of the tube through the dust-air channel 87 in the dust collection device 26, the connecting air duct 38 and the suction hole 39 of the main body. Negative pressure is applied to the sleeve 16, the sliding tube 18 and the brush 19 to the floor in the node 12 of the tube, and the dust and the air is sucked from the end of the brush 19 to a floor or the like, placed on the surface.

The air containing dust passes through the brush 19 to the floor, sliding the tube 18 and the sleeve 16, is released from the suction opening 39 of the main body through the connecting air duct 38 and is held in the first part 41 for centrifugal separation of dust collection device 26 from the suction holes 60. The air containing dust, a part of the suction holes 60, rotates along the circumference of the separation chamber 56, that is, between the body 51 of the container main body 58 of the container) and the rotating part 52 (the main body 62 of the rotating parts, the first part 41 for centrifugal separation. Large dust D is separated by centrifugal force, falls under the influence of gravity down and collected in the dust collection chamber 57, that is, between the body 51 of the container and part 63 of the large diameter of the lower end of the rotating part 52, the first is Asti 41 for centrifugal separation.

A large part of the air containing dust, rotating in the first part 41 for centrifugal separation, extends from the periphery of the holes 65 in the rotating part 52 through dust filters 53, and the rest comes out of the end openings 74 in the rotating part 52 through the pressure filter 54. That is, the amount of air passing through the end hole 74, less the amount of air passing through the peripheral holes 65. In this embodiment, the ratio of the quantities of air is, for example, approximately 9:1. When passing the air containing dust, dust filters 53 in the separation chamber 56 dust, which is smaller than coarse dust D in the air containing dust is captured dust filters 53. Part of the air containing the dust from the dust chamber 57 extends through sealing the filter 54, and the remainder passes through the filters 72 to circulate from the outer peripheral side part 63 large diameter again in part 63 of large diameter. Here, as shown by imaginary lines in figure 1, the large dust D, sucked air flow containing dust is collected in the lower end portion 63 of the large diameter of the rotating part 52 and intensely absorbed in the filters 72 and sealing the filter 54, and sealed them.

The air containing dust which has passed through bradauskas the part 52, passes through the air duct on the front side 84 of the air channel 43 and then passes into the air channel 85 on the rear side. Then, the air containing dust, plays, and exits the air channel 85 on the rear side in rectifying channel 82 rectifying portion 78 of each of the second part 42 for centrifugal separation, and passes into the main body 77 of each of the second parts for centrifugal separation by straightening the rectifier channels 82.

The air containing the dust held in the main body 77 of the second part to centrifugal separation, rotates circumferentially along the inner peripheral surface of the main body 77 of the second part to centrifugal separation with flow rate, which is higher than the speed of rotation in the housing 51 of the first container part 41 for centrifugal separation, and the fine dust separated by centrifugal force, falls under the influence of gravity from the lower end of the main body 77 of each of the second parts for centrifugal separation in the dust collection container 44 and is collected in the dust collection container 44. The air from which fine dust removed, passes through the ventilation cylindrical part 81 rectifying portion 78 of each of the second part 42 for centrifugal separation, passes into the exhaust air channel 45, and air flows are connected to each other.

In the spirit passing into the exhaust air channel 45, is sucked into the fan 31, like through the fan 31 and cools it, and then exits as exhaust air from the electric fan 31 and is discharged from the exhaust holes on the outer side of the casing 25 of the main body 13 of the vacuum cleaner.

At the completion of cleaning, the user actuates the adjusting button 22 shown in figure 5, so that the control unit turns off the fan 31. When assembled the specified number or more of dust in the dust collection chamber 57 of the first part 41 for centrifugal separation and dust collection container 44, the user detaches the dust collection device 26 from the main body 13 of the vacuum cleaner to remove the collected dust.

In accordance with the above described embodiment, since the dust collection device 26, in which the first portion 41 for centrifugal separation, and the second part 42 for centrifugal separation are connected in series, includes sealing the filter 54 on the end hole 74 of the end of the rotating part 52 of the first part 41 of the centrifugal separation, the large dust D, caught in a dust chamber 57 of the first part 41 for centrifugal separation, can intensively absorbed in sealing the filter 54 and thicken them, when part of the air containing dust, which rotates the I around the rotating part 52, passes through the end hole 74, and enters into the second part 42 for centrifugal separation. Therefore, the large dust D can be effectively compacted at the expense only of the air flow containing dust, without increasing the volume of the first part 41 for centrifugal separation (body 51 of the container) or provide a mechanical device for sealing large dust D, and, thus, the dust collection device 26 can be prevented from increasing in size and complexity of the device, and, in addition, may be collected a sufficient amount of dust. Consequently, Hoover 11 can be made compact, the number of elements is reduced, and can be made inexpensive Hoover 11.

As dust filters 53 are located on the peripheral holes 65 of the first part 41 for centrifugal separation, some of the dust from the air containing dust can be effectively trapped by passing air containing dust from the peripheral holes 65 in the second part 42 for centrifugal separation.

As many parallel rows of the second parts 42 for centrifugal separation connected with the side downstream of the first part 41 for centrifugal separation, fine dust, which is the first part 41 for centrifugal separation can not be separated under the action of centrifugal forces, can be separated under de the action of centrifugal forces more reliably the second parts 42 for centrifugal separation, and the dust collecting efficiency can be further enhanced.

Since the quantity of air containing dust passing through the end hole 74 of the first part 41 for centrifugal separation, less the amount of air that contains dust passing through the peripheral holes 65, the large dust D can be absorbed and effectively compacted sealing filter 54 through air containing dust passing through the end hole 74, a sufficient amount of air that contains dust, can be carried out in the second part 42 for centrifugal separation through the peripheral holes 65 without interference with the movement of large dust D, and can be prevented by reducing the suction power.

As fine dust, which has passed through the first portion 41 for centrifugal separation, separated by centrifugal force the second parts 42 to centrifugal separation and caught in a dust collection container 44, clogging or the like is unlikely to occur in dust-air channel 87 in this device, such as a device in which fine dust, which has passed through the first portion 41 for centrifugal separation, captured after filtering with a filter element, such as a filter, and the suction force can be maintained for a long period of time. Therefore, do not need arrange the TWT, which automatically removes dust from the filter device and the control can be further simplified, and can be further made smaller and inexpensive Hoover 11.

In addition, in the embodiment, at the location of one dust collection container 44, corresponding to all the second parts 42 for centrifugal separation, for example, can be located dust containers, respectively, corresponding to the second parts 42 for centrifugal separation.

Number of second parts 42 for centrifugal separation can be set arbitrarily, while the second part 42 to centrifugal separation (the second part 42 for centrifugal separation) can reliably separate the fine dust, which cannot be captured first part 41 for centrifugal separation, in other words, fine dust, which is like through the first part 41 for centrifugal separation.

Dust filter may not be installed on the peripheral holes 65 of the first part 41 for centrifugal separation. That is, the peripheral holes 65 may be a simple hole.

Dust collection device 26 is able to detach from the main body 13 of the cleaner casing 25 of the main body) in the Hoover 11 in accordance with this embodiment. However, even if the dust collection device is 26 are made as one piece with the main body 13 of the cleaner casing 25 of the main body), can be provided for the same work and the result. In this case, it is preferable that collected dust can be removed easily, for example, making the first part 41 for centrifugal separation, dust collection container 44 or similar removable from the main body 13 of the cleaner casing 25 of the main body).

Not limited to Hoover container type, can also be used in a vacuum cleaner of the upright type in which the brush 19 to floor is connected with the lower part of the vertical long main body 13 of the vacuum, hand vacuum, self-propelled vacuum cleaner and the like.

In addition, although power is supplied from AC General use using the device coil cord as part of the power is in the Hoover 11 in accordance with this embodiment, the battery as part of the power supply, such as a secondary battery may be installed in the main body 13 of the vacuum cleaner.
