Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vacuum cleaner that collects dust after compressing dust in a dust collection chamber.

Conventionally, various structures have been used to compress dust in a dust collection chamber using a compression device, and there are also devices that remove dust from one side of a filter at the same time as compressing the dust. In this type of vacuum cleaner, the dust in the dust collection chamber is compressed, so the dust scatters when picking up dust.

However, it is necessary to open the dust collection chamber for collecting dust, but the means for opening this is one in which the mounting surface becomes an opening when the dust collection case is removed from the main case, or There is a type in which an opening is formed by removing the filter.

The former type has the disadvantage that dust is exposed as soon as the dust collection case is removed, and the operation must be performed carefully. In addition, with the latter type, you have to touch the filter where fine dust adheres, and when you remove the filter, an opening is formed, but the filter is placed on the opening side for collecting dust. It has the disadvantage that care must be taken not to touch dust due to the position of the gripping hand. In addition to this type of case, there is also a case in which a lid that can be opened and closed is attached to the dust collecting case, and when the lid is opened, an opening is formed for discarding the dust.

However, this also has the disadvantage that the hand for gripping the lid is located on the opening side and care must be taken to prevent dust from getting on the hand when opening the lid. The present invention has been made in view of these points, and an object of the present invention is to provide a vacuum cleaner that can collect dust in an extremely hygienic manner by using a compression device that compresses dust in a dust collection chamber. That is.

The present invention directs the sliding direction of the compression device toward the opening formed in the dust collection case, and applies force to open the lid body that closes this opening from inside through dust when the compression device is operated. It is configured to give Therefore, when disposing of dust, hands are not placed on the opening side, making it possible to perform extremely hygienic operations. One implementation of the present invention will be described based on the drawings.

Reference numeral 1 denotes a main body case in which an electric blower 2 is built in. On the front end side of the main body case 1, there are an engagement hole 5 formed in a wall 4 having a communication port 3, a clamp 7 that engages and disengages from an engagement recess 6, and an engagement hole 5 formed in a wall 4 having a communication port 3. A dust collection case 9 provided with a mating protrusion 8 is connected.

The rear end of this dust collection case 9 is an opening 10 for disposing of dust, and the upper part of the dust collection case 9 is attached through this opening 10, and is provided with a rib (not shown) formed on the inner surface of the dust collection case 9. A filter device 11 is provided which is held horizontally. This filter device 11 consists of a filter frame 12, a main filter 13 such as a urethane filter, and a net filter 14 that serves as a dust collection surface.
A plurality of protrusions 15 are formed on the lower surface side of 4 in the front-rear direction. Further, a suction pipe 16 is provided on the front end side of the dust collection case 9.
A suction port 17 into which is inserted is formed in the horizontal direction.
The suction pipe 16 is made up of a non-flexible part 18 near where it is inserted and a flexible part 19 on the outer tip side. A cover 20 forming a part is attached. Inside the dust collection case 9, a compression device 22 is provided in the opening 10, and the compression device 22 is provided with a compression plate 21 that substantially matches the inner surface shape and whose upper portion is in contact with the net filter 14 of the filter device 11. This compression device 2 is provided so as to be slidable toward the
The second operating section 23 is biased leftward by a spring 24 so that its maximum protrusion amount substantially matches the non-flexible portion 18. Further, the compression plate 21 has the suction port 1
A vent hole 25 having substantially the same diameter as this suction port 17 is formed opposite to the suction port 7 . Further, the opening 10 has this opening 10.
A lid body 26 that always closes the is rotatably provided by a hinge 427. A seal backing 28 is attached to the periphery of the lid body 26 to press against the inner surface of the dust collection case 9, and when the dust collection case 9 is turned with its opening 10 side facing down, the lid body 26 opens by its own weight. The pressure contact force is adjusted so that the dust compressed by the compression operation of the compression device 22 is released without any problem. Further, the lid 26 is regulated to be substantially vertical in its closed state so that the sealing performance between the lid 26 and the wall 4 is maintained when the main body case 1 and the dust collection case 9 are connected. There is. The lid body 26 includes a main body case filter device 1.
Two communication ports 9 are formed to communicate the upper space of the main body case 1 and the main body case communication port 3. In such a configuration,
When the electric blower 2 is driven, the suction pipe 16, the suction port 17,
Communication port 25, dust collection chamber 30, filter device 11, communication port 2
9. Dust is collected in the dust collection chamber 30 by the intake air flowing to the communication port 3.
7.

Therefore, once the dust has accumulated to a certain extent, the dust is compressed by the compression device 22. At this time, since the suction port 17 and the compression direction of the compression device 22 are in the same direction, the least torque is required, and the dust that tends to accumulate near the suction port 17 can be kept away from the suction port Jl7 as much as possible. ability can be maintained. Also, the compression plate 21 at the time of compression is the net filter 14.
Since the net filter 14 contacts and slides on the protrusion 15, it is possible to vibrate the net filter 14 and move the filter device 11 itself somewhat in the front and rear directions to remove dust at the same time. In this case, since only the protrusion 15 of the net filter 14 is used, no other device or parts for removing dust are required and the cost is low. Furthermore, although a considerable stroke is required to compress dust, since the operation part 23 is provided by extending to the hard, non-flexible part 18 of the suction pipe 16, the stroke is sufficient to avoid getting in the way during use. This provides a stroke that allows for proper compression. After repeating this compression operation several times to accumulate a considerable amount of dust in the dust collection chamber 30 and finally sucking in the dust, the dust collection case 9 is moved to the main body case 1.
Remove it and throw away the dust.

When this dust collection case 9 is left alone, the opening 1 may be accidentally opened.
Even if the 0 side is turned down, the lid body 26 will not open under its own weight, so the opening 10 will not be opened and dust will not be scattered around. Then, with the opening 10 side facing down at the dust disposal place, the compression device 22 is operated to finally compress the dust, and the lid body 26 is forcibly pushed in the opening direction through the compressed dust. Dust can be disposed of by opening the door and pushing out the dust. In this way, by simply pressing the operation part 23 of the compression device 22, the dust can be compressed and the lid 26 can be pushed open to discard the dust.At the same time, the discarded dust is also pushed towards the opening 10 side, so the dust can be disposed of reliably. be able to. Further, as described above, since the stroke of the compression device 24 is large, this effect can be further improved. Furthermore, when discarding the dust, the net filter 14 is vibrated so that the attached dust can be dropped and discarded at the same time. In this embodiment, the opening 10 is provided at the rear, the filter device 11 is provided at the upper part of the interior, and the compression device 22 is provided so as to be slidable in the horizontal direction. is formed at the bottom of the dust collection case 9 and a lid 26 is provided there, and the filter device is provided with its net filter 14 at the rear inside facing the suction port 17, and the compression device is slidable in the vertical direction. The same effect can be obtained even if it is provided so as to be wetted.

As described above, the present invention includes a compression device that is slidable toward the opening, and a lid that is opened through the dust by the compression operation of the compression device when disposing of dust. The lid can be opened at the same time as the compression operation, making it easy and reliable to dispose of the dust.Also, since the dust collection surface of the filter device is parallel to the compression direction and has protrusions formed, the lid can be opened at the same time as the compression operation. Dust can be removed from the filter device with a single operation, and since the operation part of the compression device protrudes into the non-flexible part of the suction pipe, it improves the compression effect without getting in the way during use. It has effects such as being able to improve the effects of the layer.
