  The operation and action of the vacuum cleaner in the present embodiment configured as described above will be described below.

  As shown in FIG. 2 (b), the dust collector 7 of the present invention has a structure in which the lower side is opened when the waste is discarded. The operation when the dust is discarded will be specifically described. The dust collector 7 accommodated in the vacuum cleaner main body 1 is taken out from the main body accommodating portion (not shown) with the dust collecting handle portion 8d when throwing away the garbage. The taken-out dust collector 7 pushes the operating portion 12b near the handle portion 8d, thereby sliding the locking portions 11 on both sides downward via the arm portions 12a on both sides of the operating component 12. And the latching | locking part 11 slides below, the fitting with the to-be-latched part 10a distribute | arranged below the downstream filter 10 is cancelled | released, and the downstream shaft 10 has the rotating shaft provided in dust collection case 8 upper direction. Open about 110 ° in the center. Along with this, the upstream filter 9 is also opened and opened so that the dust accumulated in the dust collecting part 8b of the dust collecting case 8 can be discarded. As a result, the waste disposal operation can be easily performed with one hand by opening downward, and the lid is closed when the lid is closed, and the upper pivot shaft and the side are locked at two locations below, and the lid is held in the closed state. Can also be done reliably.

In addition, by setting the opening direction downward, it becomes easier to handle fine dust removed from the pleated filter by the jog lever 13 that accumulates in the lower part of the downstream filter 10, and it is possible to suppress the rising of dust during cleaning. . Next, details of the operation of the urging means for urging the upstream filter 9 and the downstream filter 10 in the opening direction and the fixing part of the upstream filter 9 at the time of waste disposal will be described. The total operation component stroke of the dust collector 7 taken out is 5 mm, and by pushing about 1 mm, first the locking portion 12d and the locked portion 9g, which are only the fixed portions of the upstream filter 9, are released. . By may pushed further 1-1.5 mm, locking of the lock in which the locking portion 11 and the locked portion 10a of the downstream filter 10 is released. Simultaneously with the release, the downstream filter 10 is pushed in the opening direction by a spring 15 which is a biasing means for biasing the downstream filter 10 in the opening direction. The spring 15 is located between the upstream filter 9 and the downstream filter 10, and when the waste is discarded, it plays a role of always providing a gap between the two filters even when both filters rotate, and is attached to the downstream filter 10. Fine dust removed from fine dust and pleated filter is easy to fall.

  When the operation component 12 is further pushed downward, as shown in FIG. 6, the two protruding shapes 12 c provided with inclined surfaces on the lower portion of the operation component 12 are attached to the upper portion of the dust collecting case 8 of the upstream filter 9. The operation is to push the hinge portion 9f and push the upstream filter 9 in the opening direction. When the trash is thrown away, the configuration is as shown in FIG. 8A, and the net filter 9b that collects coarse dust disposed on the upstream filter 9 is maintained in this state.

  In addition, when cleaning the pleated filter portion that collects fine dust in the downstream filter 10, if the upstream filter 9 is left on the downstream filter 10, the cleaning is difficult (cannot be performed). As shown in (b), only the upstream filter 9 is rotated to the dust collecting case 8 side, and the upstream filter 9 is fixed to the dust collecting case 8 side by the locking portion 12d and the locked portion 9g. Since the upstream filter 9 is held on the dust collecting case 8 side by nail fitting, the downstream filter 10 can be easily maintained.

  As described above, the dust collector according to the present invention reliably maintains the upstream filter and the downstream filter at a constant angle without dropping dust adhering to the downstream filter to the upstream filter side when the waste is discarded. By using a dust collector that can be discarded outside, a dust collector that is more clean and easy to use, and a vacuum cleaner that uses the dust collector can be provided.
