Description

[Detailed Description of the Invention] This invention relates to a vacuum cleaner, and its purpose is to obtain a vacuum cleaner that can dispose of dust reliably and hygienically.

This idea is to provide a rotatable lid for opening and closing the opening at the bottom of the dust collection case, and to connect the support side of the lid to the inner surface of the dust collection case on the support side when the lid is closed. It is characterized by a series of protruding walls.

Therefore, by providing a continuous wall on the support side of the lid, the wall can push out the dust when the lid is opened, which makes it possible to dispose of dust reliably and to maintain hygiene. It is.

An embodiment of this invention will be explained based on the drawings.

Reference numeral 1 denotes a main body case with a built-in electric blower (not shown), and a dust collection case 2 to which the front end of the main case 1 is connected has a filter section 3 detachably attached to the main case 1 side. is provided.

The filter section 3 consists of a filter frame 4, a suction surface 5 of the filter frame 4 which is a net filter, a sponge-like filter 6 on the inner surface of the suction surface 5, and a filter 7 folded in a zigzag shape.

The periphery of the rear wall 8 of this filter frame 4 is provided with the dust collecting case 2.
A seal backing 9 that maintains airtightness with the inner surface of the main body case 1 is fitted, and a seal backing 11 that maintains airtightness with the front end wall 10 of the main body case 1 is fitted on the opening edge of the rear wall 8. It is fitted.

A handle 12 is formed at the top of the dust collection case 2, a suction port 13 is formed at the front end, and an opening 14 for disposing of dust is formed at the bottom.

Further, a lid 15 for opening and closing the opening 14 is provided with its front end rotatably attached to a hinge 16 provided at the lower front end of the dust collecting case 2.

A wall 18 that is located on the hinge 16 side and is joined to the inner surface 17 of the dust collection case 2 is connected to the lid body 15 at a substantially right angle.

Further, an L-shaped engagement piece 19 is formed at the rear end of the lid 15.

A clamp 21 that engages with a retaining hole 20 formed in the main body case 1 is provided on the handle 12 so as to be slidable while being biased upward.

Further, the lid body 15 is attached to the connecting portion side of the dust collection case 2 with the main body case by using the rear wall 8 of the filter frame 4.
A clamp 22 that engages with the engaging piece 19 is rotatably provided while being biased in the locking direction by a spring (not shown).

A frame-shaped release body 23 is provided on the connecting portion side of the dust collection case 2 with the main body case 1 so as to be movable up and down, and a spring 25 is supported at one end by a spring receiver 24 formed on the rear wall 8. is urged upward by.

The top of the release body 230 faces the indenter 26 formed on the clamp 21 at a predetermined distance.

The gap between the opening edge of the opening 14 and the lid 15 is sealed by a seal backing 2T.

In the past, a compression plate 29 was provided on the lid 15 so as to be able to move up and down while being biased upward to compress dust by having a tab 28 projecting upward.

In such a configuration, the dust accumulated in the dust collection case 2 is compressed by the compression plate 29 by pushing the knob 28, and is located between the wall 18 and the suction surface 5 serving as a net filter. .

When disposing of dust, the user grasps the handle 12 of the dust collection case 2 and presses the clamp 21 with the thumb to disengage the clamp 21 from the engagement hole 20.

If the dust collection case 2 is lifted up, the engagement between the engagement piece 19 and the holding portion 30 of the main body case 1 is also disengaged.

If the clamp 21 is pushed deeper while still in the trench state, the release body 23 is pushed by the indenter 26 and descends to the clamp 21.
Forcibly rotate it in the unlock direction.

As a result, the lid body 15 rotates around the hinge 16,
The compressed dust is discarded through the opening 14.

When the lid 15 rotates, the wall 18 formed on the rotation center side also rotates, so that the dust inside the dust collection case 2 can be forcibly pushed out.

In particular, even dust that gets caught on the suction surface 5 and is difficult to be discharged can be reliably discharged.

Further, during these dust disposal operations, there is no need to directly touch the dust with your hands, making it sanitary.

Incidentally, if the lower half of the suction surface 5 is inclined (widens towards the opening 14) in accordance with the rotation locus of the tip of the wall 18, dust can be discharged even better.

As mentioned above, this design has a continuous wall protruding into the dust collection case on the support side of the lid, so when the lid opens, this wall will forcefully remove dust that is likely to get caught in filters, etc. This allows the dust to be disposed of reliably, and also has the effect of being sanitary since the dust does not come into direct contact with the hands.
