Description

[Detailed description of the invention] The present invention relates to a vacuum cleaner.

It is common practice to transfer the dust from the dust case to a dust bag and throw away the dust, but when the dust bag is inserted into the dust case, the dust collects and makes your hands dirty, which is unhygienic. In addition, it is necessary to attach packing to the dust case to seal the bottom lid, and in addition, a bumper made of a soft material to protect furniture and the like must be attached.

These packings and bumpers are each separately molded and separately attached, and therefore have the disadvantage of increased manufacturing man-hours. This invention was made in view of the above-mentioned points, and it is possible to simultaneously achieve the sealing function of the opening and the bumper function of the outer periphery with a simple structure in a type of device in which the bottom cover is opened and the dust is thrown away. The purpose is to obtain a vacuum cleaner that can.

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

1 is a main body case, and the inside of this main body case 1 is an electric chamber in which an electric blower 2 is housed.

Next, a dust case 4 is provided which is detachably connected to the main body case 1 by a clamp 3. This dust case 4 is formed with a suction port 5 and a dust collection chamber 7 in which an opening 6 is formed in iOO. The dust collection chamber 7 has a compression chamber 8
and a filter unit 9 are provided. The filter unit 9 has a net filter 13 attached to a filter frame 12 that accommodates filter units 10 and 11, and a storage section 14 is provided at the bottom between the net filter 13 and the filter frame 12.
is formed. Next, a bottom cover 15 is attached to the lower part of the dust case 4 so as to be movable up and down. Bottom lid 15
The end of the rotation path is locked by a clamp 16 provided on the exhaust side of the dust case 4. A frame body 18, which is a holding portion that holds the opening edge of the dust disposal bag 17 in an open state, is elastically fitted below the inner surface of the dust collection chamber 7.
This frame body 18 is prevented from floating downward by the downward step portion 19 of the dust case 4, and from moving downward by a rib 20 formed on the bottom cover 15. Also, frame 1
8, a joint 21 is formed on the exhaust side of the filter frame 12 to which a part of the dust disposal bag 17 is joined, and the joint 21 is attached downward by its own elasticity. A pressed knob 22 is attached. This knob 22
Nails 23 are formed near the tip of the net filter 13 and the lower end of the net filter 13 to engage with each other. A slope 24 is formed on the inner surface of the frame 18, excluding the joint portion 21, and slopes outward as it goes upward. A part of the dust disposal bag 17 is folded up and stored in the storage section 14. However, the dust case 4
A backing 25 is attached to the lower part. As shown in FIGS. 5 to 7, this backing 25 includes a seal portion 27 that is fitted to the inner peripheral surface of the outer wall 26 of the dust case 4 to keep the bottom cover 5 airtight, and a front end of the outer wall 26 and Bumper parts 28 covering both outer sides are integrally molded while being connected by a connecting part 29. A notch 30 through which the connecting portion 29 is inserted is formed in the outer wall 26 of the dust case 4 from the lower edge. Furthermore, a partition wall 31 extending from the outer periphery of the frame body 18 toward the inner surface of the seal portion 27 is formed in the lower part of the dust case 4 . A locking portion 32 is formed between the partition wall 31 and the outer wall 26 to prevent the backing 25 from moving upward.
A locking portion 33 for suppressing the downward movement of the outer wall 26 is formed at the lower edge of the outer wall 26. In such a configuration, the dust collection chamber 7
That's trash! Dust accumulates, but when disposing of the dust, operate the clamp 3 to separate the dust case 4 from the main case 1, then hold the clamp 16 to disengage it and free the bottom cover 15. 15 is in a state where it can be rotated downward. When the bottom cover 15 is opened and the frame body 18 is disengaged from the net filter 13, the frame body 18 returns to its original position by its own elastic force and protrudes downward, since it was attached while being bent. As a result, the garbage disposal bag 17 is pulled out due to the weight of the garbage, and its opening edge is
Since the dust case 8 is held in an open state, the dust in the dust case 4 is transferred to the dust disposal bag 17.

The slope 24 of the frame body 18 functions to smoothly transfer all dirt and dust, and dust does not accumulate on the upper edge of the frame body 18. Therefore, it is possible to dispose of dust easily and hygienically without getting your hands dirty and without dust flying around. Then, the opening edge of the dust disposal bag 17 is removed from the frame 18 and bound with string or tape. Then,
Attach an unused garbage disposal bag 17 to the frame 18, store a part in the storage section 14, bend the knob 22, and remove the net filter 1.
3 with the claws 23, and the bottom cover 15 is closed in preparation for the next disposal of dust. The partition wall 31 prevents the opening edge of the dust bag 17 from being pinched between the seal portion 27 and the bottom lid 15, so that the airtightness of the bottom lid 15 is not impaired. It should be noted that the locking portion 32 is not absolutely necessary because the downward facing surface of the notch 30 formed from the lower edge of the outer wall 26 of the dust case 4 prevents the backing from moving upward.

Since this invention is configured as described above, the dust bag can be set without dust in the dust collection chamber, and the dust can be transferred to the dust bag by simply opening the bottom lid. You can easily dispose of dust without spilling dust or getting your hands dirty, and by integrally molding the seal part that seals the bottom lid and the bumper part,
The number of parts and assembly man-hours can be reduced, and since it is only necessary to hold either the seal part or the bumper part, the backing holding structure can be simplified. By inserting the connecting part of the backing, it is possible to position the backing and prevent it from moving upward, and by forming a locking part in the dust case, it is possible to prevent the backing from moving downward. It has the following effects.
