At this time, a dust drop lip 34 that contacts each partition plate 28 is provided on both sides 32b of the discharge promotion plate 32 so that dust attached to the pair of partition plates 28 can be scraped off.

  Next, the operation of this embodiment will be described.

  When the electric blower 19 is operated by operating the operation portion 13a of the hand control tube 13 shown in FIGS. 1 and 2 to operate the electric blower 19, the inside of the electric blower 19 is depressurized. When air is sucked in (not shown), air flows in the air passage from the attachment port 24 to the discharge port 26 in the container body 22 of the dust collection container 20. As a result, an air flow is formed from the suction port body 15 through the extension tube 14, the hand operation tube 13, and the hose 12 to the mounting port 24, and dust sucked together with air enters the dust collecting container 20 from the mounting port 24. Sent.

  In the dust collecting container 20, as shown in FIG. 4, an air flow indicated by an arrow A is formed by an air path created by the mounting port 24 and the discharge port 26, and a part of the air collecting port is indicated by an arrow B. It flows to 29. Dust and air that have entered the dust collection container 20 from the attachment port 24 travel substantially vertically downward in the dust collection container 20 as is well known, and the dust is collected by inertia and gravity. The air is directed toward the bottom 20a of the air outlet 20, while the air passes through the discharge port 26 or the ventilation port 29 toward the suction port (not shown) of the electric blower 19. Thereby, dust is collected in the bottom 20a of the dust collecting container 20. At this time, even if the light dust is not separated but is entrained in the air and directed toward the discharge port 26 or the ventilation port 29, the net filter 33 is disposed at a position overlapping the discharge port 26 of the discharge promotion plate 32. Since the side filter 30 is provided, the dust does not pass through the discharge port 26 or the ventilation port 29. In addition, the two air vents 29, together with the partition plates 28 and the pair of sub exhaust ports 27, form a bypass path for the air path portion passing through the exhaust port 26. For example, the net filter 33 is clogged due to clogging. Even if it becomes impossible to form the air flow indicated by A, the suction force of the vacuum cleaner 10 is not significantly reduced by the air flow as indicated by the arrow B, and the dust is collected on the bottom 20a of the dust collecting container 20. Can be stored.

  In order to throw away the dust accumulated in the dust collecting container 20, the lid 18 of the main body case 17 is opened (see FIG. 2), the dust collecting container 20 is taken out from the main body case 17, and the dust collecting container 20 is placed above the trash can, for example. Bring. When the button portion 21a shown in FIG. 4 provided on the handle 21 of the dust collecting container 20 is pushed down, the rod 21b is pushed down, and the rod 21b disengages from the locking portion 23a of the locking piece 22d, thereby releasing the discharge lid. 23 rotates by its own weight along the swinging direction of the hinge 31, and the opening 22a of the container body 22 is opened as shown in FIG. When the discharge lid 23 rotates, the discharge promotion plate 32 provided on the discharge lid 23 also rotates integrally with the discharge lid 23, and the front surface of the discharge promotion plate 32 accumulates on the bottom 20 a of the dust collecting container 20 during this rotation. Since the bottom 20a of the dust collecting container 20 is moved while pushing out the dust, the dust accumulated in the dust collecting container 20 is surely scraped out. At this time, the both dust filters lip 34 provided on the discharge promoting plate 32 move while being in contact with the pair of partition plates 28, whereby both side filters 30 provided on the partition plates 28, particularly the both partition plates 28. Dust adhering to the surface is also surely scraped off. Moreover, since the lower part of the dust collecting container 20 is opened by opening the discharge lid 23, the dust discharged from the dust collecting container 20 by the discharge promoting plate 32 naturally falls downward according to gravity, for example, downward. It can be thrown into the trash can. At this time, since the dust is pushed out from the open portion 22a of the dust collecting container 20 in the natural fall direction, even if the dust is vigorously discharged from the dust collecting container 20 by the discharge promoting plate 32, the dust naturally falls downward as it is. So don't get scattered.

  Therefore, during the operation of opening the discharge lid 23, the dust accumulated in the dust collecting container 20 is surely discharged by the discharge promotion plate 32, and the dust adhering to both the partition plates 28 and both the side filters 30 is dropped. It is scraped off by the lip 34.

  Further, each time when the discharge lid 23 of the dust collecting container 20 is opened, the both dust dropping lips 34 scrape off the dust on the side filter 30, so that the side filter 30 is less likely to be clogged and the life of the side filter 30 can be extended. .

  Therefore, in the dust collecting container 20 of the electric vacuum cleaner according to the present invention, the dust collected in the dust collecting container 20 can be surely discharged without being manually scraped by simply pressing down the button portion 21a provided on the handle 21. it can.

  Both dust drop lips 34 abut against both partition plates 28 and can scrape off dust adhering to both partition plates 28 and side filter 30 each time the discharge lid 23 of the dust collecting container 20 is opened. That's fine. For example, short hairs may be provided on both sides 32b of the discharge promotion plate 32 without any gaps, and brushes protruding from the discharge promotion plate 32 along both sides 32b may be provided. Since both dust drop lips 34 move while in contact with both partition plates 28, it is desirable to form the dust drop lips 34 with a softer member than both partition plates 28.

  In the above embodiment, the discharge promoting plate 32 is provided with the net filter 33 in order to prevent dust from passing through the through hole 32a. However, the discharge promoting plate 32 is disposed on the bottom 20a of the dust collecting container 20. It is only necessary to scrape the accumulated dust, and the net filter 33 may not be provided. In this case, since dust passes through the discharge port 26, it is desirable to provide a net filter 33 at the discharge port 26.

  The through hole 32a of the discharge promotion plate 32 only needs to allow air to pass through the discharge port 26 and scrape out dust, and the shape of the discharge promotion plate 32 is not limited to the above-described embodiment. For example, the shape of the through hole 32a of the discharge promotion plate 32 may be formed as a through hole having a plurality of circular cross sections, and the discharge promotion plate 32 is formed to have a plurality of bars extending vertically like a rake. May be.

  The vacuum cleaner 10 separates dust from the air by directing the air flow downward in the vertical direction in the dust collecting container 20. For example, the vacuum cleaner 10 vortexes air containing dust in the dust collecting container 20. Thus, the cyclone type electric vacuum cleaner 10 that generates centrifugal force on the dust to separate the dust and the air may be used, and is not limited to the above-described embodiment.

  The side filters 30 provided at both the ventilation openings 29 may be attached to the partition plate 28 so as to cover the ventilation openings 29, or may be provided so as to be fitted to the ventilation openings 29. However, both dust drop lips 34 move while in contact with both partition plates 28 to scrape off dust adhering to both partition plates 28 and side filter 30. Therefore, in order to increase the efficiency of this scraping, the partition plates are used. It is desirable that the side filter 30 and the side filter 30 be provided flush with each other on the side in contact with the dust drop lips 34.

  Although the discharge lid 23 of the dust collecting container 20 is positioned vertically downward when housed in the vacuum cleaner 10, it is not limited to the above-described embodiment. For example, even if a discharge lid is provided on the side of the container body 22 and a discharge promoting member is provided so as to extend in a direction perpendicular to the discharge lid, it should be positioned below when discharging dust from the dust collection container 20. That's fine.
