Description

[Detailed description of the invention] The present invention relates to a vacuum cleaner, in which dust adhering to the surface of the carpet is separated by a rotating brush that rubs against the surface to be cleaned, and this dust is sucked by an electric blower. The present invention relates to an airtight structure for a dust collection case of a vacuum cleaner, in which the dust is collected by a filter and deposited in the dust collection case.

Conventional vacuum cleaners of this type store a dust collection case in a dust collection case storage area formed between the rotary brush installation part of the vacuum cleaner body and the suction side of the electric blower. A structure was adopted in which the opening for attaching the dust collection case was closed with a lid.

This structure has the disadvantage that the suction opening of the dust collecting case must be kept airtight by the dust collecting case storage part and the lid plate of the main body, making the airtight structure complicated, making it difficult to assemble, and making it expensive. There is.

The present invention was developed in view of the above drawbacks, and by attaching the dust collection case to the dust collection case storage part of the main body, the suction opening of the dust collection case is airtightly communicated with the suction port, and the filter side is also To provide a vacuum cleaner which is connected to the suction side of an electric blower and whose dust collection case is easily kept airtight.

Next, the structure of an embodiment of the present invention will be explained with reference to the drawings.

Reference numeral 1 denotes a vacuum cleaner body, which is composed of an upper case member 2 and a lower case member 3 coupled to the upper case member 3.

In the front part of the main body 1, an arrangement part 5 for the rotary brush 4 is formed in a cylindrical shape with the left-right direction as the axial direction, and an opening part 6 is formed in the lower part of this arrangement part 5. The tips of the brushes 7 of the rotary brush 4, which is rotatably mounted on the rotary brush 5, protrude.

A dust collection case storage section 8 is formed in the rear part of the main body 1 adjacent to the installation section 5, and the installation section 5 and the storage section 8 are separated by an arc-shaped partition wall 9 shaped along the rotary brush 4. It is being

A suction port 10 is formed in an upwardly facing surface of the partition wall 9.

Further, a mounting opening 11 for opening and closing the dust collection case storage section 8 is formed in the upper part of the main body 1.

Further, a clamp locking portion 12 is formed at the front edge of the mounting opening 11, and a locking protrusion 13 is formed at the rear edge.

Furthermore, an electric chamber 15 partitioned by a partition wall 14 is formed at the rear of the main body 1, and an electric blower 16 is disposed in this electric chamber 15, and the suction side of the electric blower 16 is connected to the partition wall 14. The discharge side of the electric blower 16 is airtightly communicated with the formed vent 7, and the discharge port 1 is opened on the top surface of the main body 1.
It is connected to 8.

The rotary brush 4 is linked to the electric part of the electric blower 16 via a belt 19.

Further, the main body 1 is provided with a front wheel 20 and a rear wheel 21, and an operating rod 22 is rotatably attached to the rear part.

Next, reference numeral 23 denotes a dust collection case that is detachably attached to the dust collection case storage section 8 of the main body 1 through the mounting opening 11, and the front surface of this dust collection case 23 is an arcuate surface along the front partition wall 9. A suction opening 24 is formed facing downward on the front surface of the partition wall 9 so as to face the suction opening 10 , and a suction opening 24 is formed in close contact with the periphery of the suction opening 10 . A backing 25 is attached to keep the suction port 10 airtight.

In addition, a backing 35 attached to a support frame 28 of a filter 27 is airtightly and removably attached to the rear filter side opening 26 of the dust collection case 23, and a backing 35 attached to the support frame 28 of the filter 27 is attached to the rear filter side opening 26 of the rear partition wall 14. A backing 29 is provided around the air blower 17 to airtightly contact the dust collection case 23 and connect the dust collection case 23 to the suction side of the electric blower 16 .

Reference numeral 30 denotes a pressure plate, which is attached to a knob shaft 31 that is rotatably attached to the upper surface of the dust collection case 23, and the tip edge 32 of the pressure plate 30 faces the suction opening 24 and can be rotated in the left-right direction. It is designed to be moved.

A tip edge 32 of this pressing plate 30 is formed into an arcuate edge along the front surface of the dust collecting case 23.

Further, an operating knob 3 is provided at the end protruding from the upper surface of the knob shaft 31.
3 is provided.

Note that the knob shaft 33 is attached to the airtight ring 3 on the top surface of the dust collection case 23.
It is rotatably attached via 4.

Further, a clamp locking part 12 is provided at the front part of the dust collection case 23.
A clamp 35 is provided to be locked to the locking protrusion 13, and a retaining step portion 36 to be locked to the locking protrusion 13 is formed at the rear portion.

Next, the operation of this embodiment will be explained.

The dust collection case 23 is attached through the attachment opening 11 of the main body 1.

At this time, the engaging step portion 36 is engaged with the locking protrusion 13 to lock the clamp 35 to the clamp locking portion 12 .

In this state, the suction opening 24 of the dust collection case 23 is connected to the suction port 10.
The filter 27 side is airtightly communicated with the suction side of the electric blower 16 via the backing 29 of the support frame 28 .

Then, move the main body 1 to the operating lever 22 to move the surface to be cleaned, such as a carpet.
When the brush 4 is pushed and moved and the electric blower 16 is driven at the same time, the rotary brush 4 is rotated via the belt 19, and the dust adhering to the surface to be cleaned is separated, and this separated dust is removed by the electric blower 16. The dust is sucked into the dust collection case 23 through the suction port 10 through the opening 6 of the main body 1 and introduced into the dust collection case 23 through the suction opening 24 of the dust collection case 23. is deposited in

In addition, the filtered air passes through the electric blower 16 to the discharge port 18.
More exhaust.

When dust is accumulated in the dust collecting case 23, the operating knob 33 is rotated left and right to press and compress the dust rearward, and to compress and accumulate the dust on the front side of the filter 27.

In this state, a space is formed on the suction opening 24 side of the dust collection case 23, and is prepared for the next dust collection.

The dust compressed to the filter 27 side performs a fine dust filtration action, thereby preventing the filter 27 from clogging.

Note that in the configuration of the above embodiment, the suction opening 2 of the dust collection case 23
Although the structure in which the backing 25 is attached to the main body 1 has been described, the backing 25 may be attached to the suction port 10 of the main body 1.

According to the present invention, the suction opening of the dust collection case, which is detachably attached to the dust collection case storage part of the vacuum cleaner main body, is airtightly communicated with the suction port of the main body through the backing, and the filter side opening is connected through the backing. It is airtightly connected to the suction side of the electric blower, and the dust collection case can be reliably maintained airtight by simply attaching it to the dust collection case storage area, and the dust collection case storage area on the main unit has an airtight structure. This eliminates the need for airtightness, has a simple airtight structure, and can be assembled at low cost.
