A plurality of small protrusions 124g are formed on the lower surface of the compression body 124a facing the bottom lid unit 140 of the dust collection cup 111 (see FIG. 7). These protrusions 124g have a function of contacting and pushing down the dust and dust when the compression unit main body 124a moves downward. With this function, the compression rate of the dust and dust can be increased. Further, when throwing away the compressed dust and dust, for example, when the bottom lid body 141 described later is opened and thrown away, the degree of adhesion between the dust and dust and the compression portion 124 is reduced by the protrusion 124g, and the dust and dust are discarded. Since dust becomes easy to leave | separate from the compression part 124, operativity improves.

(Bottom lid unit 140)
FIG. 10 is an exploded perspective view showing the configuration of the bottom lid unit 140. As shown in FIG. 10, the bottom lid unit 140 includes a bottom lid body 141, a link pin 142 (connection member), a packing 143, and a support portion 144.

  An opening 141 a is formed in the center portion of the bottom lid body 141. As shown in FIG. 10, the opening 141a has a cylindrical shape protruding upward. For this reason, the lower surface of the bottom lid body 141 opposite to the dust collection cup 111 has a concave shape recessed upward.

  The link pin 142 is provided so as to penetrate the opening 141a. A packing 143 is provided between the opening 141 a and the link pin 142. The link pin 142 can move upward or downward through the opening 141a.

  The support portion 144 has a cylindrical shape and is accommodated in a concave portion on the lower surface of the bottom lid body 141 opposite to the dust collection cup 111. The support portion 144 abuts on the flange portion 142 a of the link pin 142 and stops the downward movement of the link pin 142.

  The support portion 144 is provided with an opening 144a. When the dust collector 100 is mounted on the mounting portion 205 of the driving device 200, the protrusion 206 provided on the mounting portion 205 is configured to penetrate the opening 144a.

(Operation of vacuum cleaner)
The operation of the vacuum cleaner according to this embodiment will be described below. First, when the electric vacuum cleaner is operated, the control device of the driving device 200 operates the electric blower 203 and sucks air from the air inlet portion. The air sucked from the intake port portion flows into the cleaner body 1 through the connection pipe and the connection hose and through the connection portion 201 connected to the connection hose. The dust-containing air that has flowed into the cleaner body 1 flows into the dust collector 100. The dust-containing air that has flowed into the inflow port 113 of the dust collector 100 passes through the upper cover unit 130 via the separation path X indicated by the arrows in FIGS. It is discharged and sucked into the electric blower 203 of the driving device 200.

  In the dust collector 100, the upper part acts as the first centrifugal separator 70 (cyclone part) with the upper surface of the compressing part 124 as a boundary. That is, in the dust collector 100, the first centrifuge 70 (first cylindrical centrifuge) includes the inner surface of the first dust collecting chamber 111A in the dust collection cup 111, the outer peripheral surface of the inner cylinder 123, and the like. It is the turning air path comprised by these. The inflow port 113 opens in the tangential direction of the swirling air passage formed by the first centrifugal separator 70. Therefore, the dust-containing air that has flowed in through the inflow port 113 swirls in the swirling air path formed by the first centrifugal separator 70 as in the separation path X of FIG. Dust is centrifuged. Of the dust that has been centrifuged, relatively large coarse dust (first dust) is dropped along the inner surface of the first dust collecting chamber 111A of the dust collecting cup 111 by the action of centrifugal force, and the compression unit 124. Is accumulated below. Relatively large coarse dust (first dust) accumulates on the bottom of the dust collection cup 111.

  The air from which the coarse dust has been separated passes through the inner cylinder portion 123 (see the separation path X in FIG. 2). At this time, the relatively small fine dust (second dust) that has not been separated by the first centrifugal separator 70 is, together with the air flow, the mesh wound around the trunk 123c through the slit 123b of the inner cylinder 123. Ascends through the filter. On the other hand, the coarse dust is filtered by a mesh filter wound around the trunk portion 123c. The air that has passed through the inner cylinder portion 123 passes through the upper lid main body 121 and flows from the upper lid main body 121 into each of the second centrifugal separators 80 via the inflow port 81.

  In the second centrifugal separator 80, the inflow port 81 into which the dust-containing air flows is opened in the tangential direction of the swirl flow path of the air formed between the swirl tube portion 82 and the exhaust tube 83. Therefore, the dust-containing air that has flowed in from the inflow port 81 swirls along the inner peripheral surface of the swirl tube portion 82 as in the separation path X shown in FIG. The second centrifugal separator 80 is configured so that the turning radius of the dust-containing air is smaller than the turning radius in the first centrifugal separator 70 and the turning speed is higher than the turning speed in the first centrifugal separator 70. Designed. Thereby, with respect to the dust-containing air that has passed through the first centrifugal separator 70, dust that is smaller than the coarse dust separated by the first centrifugal separator 70, that is, fine dust, can be separated. Therefore, the fine dust (second dust) in the dust-containing air is centrifuged by the swirling of the air in the second centrifugal separator 80, falls along the inner peripheral surface of the swivel cylinder portion 82, and the discharge port 82a enters the second dust collection chamber 111B, and is finally stored in the bottom lid body 141 of the bottom lid unit 140 in the second dust collection chamber 111B.

  The air from which the fine dust (second dust) has been separated passes through the exhaust pipe 83 provided at the center of each second centrifugal separator 80 and is discharged from the outlet 83a (FIG. 5B). )).

  The air discharged from the outlet 83a passes through the upper cover unit 130 and is discharged from the dust collector 100 (see the separation path X in FIGS. 2 and 5B).

(Compression mechanism by the compression unit 124)
When the cleaning is completed, the user stops the operation of the electric blower 203. When the user separates the dust collector 100 from the driving device 200, the vacuum cleaner according to the present embodiment moves the compression unit 124 in the first dust collection chamber 111A toward the bottom lid unit 140, and the bottom A compression mechanism for compressing dust accumulated in the lid unit 140 is provided. By providing such a compression mechanism, when the user opens the bottom lid unit 140, the user can discard dust in a compressed state. Therefore, the dust in the dust collector 100 can be discarded efficiently.

  Hereinafter, the compression mechanism by the compression unit 124 will be described with reference to FIGS. 2, 5 (a) and 5 (b), FIG. 11 (a) and (b), and FIG. 12. FIG. 11 is a cross-sectional view showing the configuration of the inner cylinder unit 122. FIG. 11A shows the configuration when the dust collector 100 is mounted on the drive device 200, and FIG. These show a configuration when the dust collector 100 is separated from the drive device 200. FIG. 12 is a cross-sectional view showing the configuration of the dust collector 100 when the bottom lid unit 140 is opened.

  As shown in FIG. 2 and FIG. 11A, when the dust collector 100 is attached to the driving device 200, the protruding portion 206 provided on the bottom surface of the mounting portion 205 is formed on the bottom lid unit 140. The link pin 142 is engaged, and the link pin 142 is pushed upward. The link pin 142 pushes the concave portion 124b of the compression portion 124 upward. The compression part 124 is urged downward with respect to the inner cylinder part 123 by the coil spring 125. Therefore, when the dust collector 100 is attached to the drive device 200, the downward movement due to the bias of the coil spring 125 is locked by the link pin 142 and the protruding portion 206 of the compression portion 124. As a result, when the dust collector 100 is attached to the driving device 200, the distance between the lower surface of the compression unit 124 and the bottom lid body 141 is maintained at the distance D1.

  When the dust collector 100 is separated from the driving device 200, as shown in FIGS. 5A and 5B and FIG. 11B, the protrusion 206 and the link pin 142 of the mounting portion 205. Is released, and the protrusion 206 is released. The compression portion 124 is pushed down together with the link pin 142 by the elastic force due to the downward bias of the coil spring 125. And the movement of the compression part 124 is latched by the latching piece 123g of the 1st axial part 123e engaging with the locking piece 124f of the 2nd axial part 124e. As a result, the distance between the lower surface of the compression unit 124 and the bottom lid main body 141 becomes the optimum distance D2 for dust compression by the compression unit 124.

  Thus, in the vacuum cleaner according to the present embodiment, when the user separates the dust collector 100 from the drive device 200, the compression unit 124 in the first dust collection chamber 111A moves toward the bottom lid unit 140. It moves and compresses the dust accumulated in the bottom lid unit 140. The compressed dust is continuously compressed so that the compressed dust does not expand again. Further, when the dust is thrown away, the rising of the dust is suppressed by compressing the dust. In addition, the frequency | count which isolate | separates the dust collector 100 from the drive device 200 is not restricted to once, and may be multiple times as needed. Thereby, the compression rate of dust can be raised.

  Thereafter, as shown in FIG. 12, when the user opens the bottom lid unit 140, the dust compressed by the compression unit 124 is discarded. In the dust collector 100 according to the present embodiment, the dust already accumulated in the bottom lid unit 140 is compressed by the compression unit 124 before the user opens the bottom lid unit 140.

  The vertical dimensions of the inner cylinder portion 123, the compression portion 124, the link pin 142, and the protruding portion 206 are the distance D2 optimum for the compression of dust by the compression portion 124, the dimensions of the first dust collection chamber 111A, and the first dimension. It can be set as appropriate according to the amount of dust collected in the one dust collection chamber 111A. Further, the elastic force, that is, the compression rate of the coil spring 125 can be set as appropriate.

  Further, in the configurations shown in FIGS. 2 and 5 (a) and (b), and FIG. 11 (a) and (b), the compression portion 124 and the link pin 142 are provided to be detachable. It was. However, the vacuum cleaner according to the present embodiment is not limited to such a configuration, and may be any configuration as long as the compression mechanism by the compression unit 124 described above can be realized. For example, the compression part 124 and the link pin 142 may be integrally molded or bonded.
