Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vacuum cleaner in which an electric case and a dust collection case are connected in parallel.

In this type of case, the electric case and the dust collection case are connected by a clamp, and the clamp is also placed on the side of the electric case so that it can be operated with the thumb when gripping the handle of the dust collection case. is common. The object of the present invention is to provide a vacuum cleaner whose lid can be removed with one touch to easily dispose of dust.

An embodiment of the present invention will be described based on the drawings. 1 is an electric case with a built-in electric blower (not shown).

The dust collection case 2 connected to the } side of the electric case 1 has a filter section 3 detachably attached to the electric case 1 side. The filter section 3 consists of a filter frame 4 and filters 5 and 6 held by the filter frame 4. The inner side surrounded by the filter frame 4 is an air passage 7. A space 8 is provided around the air passage 7 by making the filter frame 4 smaller than the inner surface of the dust collection case 2.
is formed. Further, a seal packing 10 for maintaining airtightness between the rear wall 9 of the filter frame 4 and the inner surface of the dust collection case 2 is fitted to the green surrounding the rear wall 9 of the filter frame 4. A seal packing 12 is fitted to maintain airtightness between the edges and the edge 11. Further, a handle 13 is formed on the upper part of the dust collecting case 2, a suction row 4 is formed on the front end, and a closing part 15 is formed on the bottom surface. Furthermore, a lid 16 that opens and closes this opening □ portion 15
The front end of the dust collection case 2 is rotatably attached to a hinge 17 provided at the front end of the dust collection case 2. 1' at the rear end of this lid 16.
A letter-shaped engagement piece 18 is formed. A clamp A20 that engages with an engagement hole 19 formed in the electric case 1 is provided on the electric case side of the handle 13 so as to be slidable while being biased upward. Further, on the side where the dust collection case 2 is connected to the electric case 1, a clamp B21 that engages with the engagement piece 18 of the lid 16 using the rear wall 9 of the filter frame 4 is mounted by a spring (not shown). It is rotatably provided while being biased in the locking direction. That is, the protruding piece 22 formed below the rear wall 9 is a support portion of the clamp B21. Alternatively, the protrusions 22 may be formed on both sides of the outer frame of the dust collection case 2. On the side of the dust collection case 2 connected to the electric case, a release operation section 23 is provided so as to be vertically movable using the space 8. This release operation part 23 is frame-shaped and is biased upward by a spring 25 whose one end is supported by a spring receiver 24 formed on the rear wall 9 of the filter frame 4. The top of the release operation section 23 faces the indenter 26 of the clamp A20 at a predetermined distance. The gap between the mouth edge of the opening 15 and the lid 16 is sealed by a seal packing 27. Further, the dust collection case 2 is provided with a compression plate 29 which is biased upward and is movable up and down, with a knob 28 projecting upward to compress dust. In such a configuration, the dust collected in the dust collection case 2 is compressed by the compression plate 29 by pressing the knob part 28.

When disposing of dust, grasp the handle 13 of the dust collection case 2 with the left or right hand. At this time, in order to operate the clamp A20, it is natural and common to hold the clamp A20 with the thumb facing toward the electric case. Therefore, the clamp A2 comes off by pressing with the thumb. Dust collection case 2
If you lift the engaging piece 18 and the holding part 30 of the electric case
It also disengages. Then, keep clamp A in the same state.
If you push 20 deeper, the release operation part 23 will release the clamp A2.
Since the clamp B21 is connected in an interlocking manner, the spring 25 is moved downward and the clamp B21 is forcibly rotated in the unlocking direction. Accordingly, the lid 16 pivots about the hinge 17 and dust is thrown away from the closing part 15. in this way,
The lid 16 can be opened with one touch without changing the handle 13 of the dust collection case 2. In addition, by making the air passage 7 smaller than the inner surface of the dust collection case 2 and providing the release operation part 23 in the space 8 formed around the air passage 7, the release operation part 23 is hidden from the surface and has a beautiful appearance. In addition, there is no need to use extra seal packing because dust does not scatter from the gap unlike when the release operation part 23 protrudes from the surface of the dust collection case 2. Furthermore, since the release operation part 23 is hidden from the surface of the dust collection case 2, it is possible that the cover 16 may be accidentally touched or accidentally operated.
Do not open it and scatter dust. As described above, this invention has a release operation part for unlocking the lid on the side where the dust collection case is connected to the electric case, so that the dust collection case can be removed from the electric case by operating the clamp A. You can operate the release operation part without changing the
As a result, the lid can be opened with a single touch to dispose of dust extremely easily, and the release operation part is located within the space formed around the air path, so it can be hidden from the surface and improve the experience. Also, there is no chance of opening the lid by touching it.
