DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a dust collector.

[0002]

2. Description of the Related Art Conventionally, dust collectors such as household vacuum cleaners and blackboard wiping cleaners generally include a filter for separating dust in the air for collecting dust and a dust separated by the filter. And a dust storage unit that accumulates the dust are integrally formed.

[0003]

However, in the above-mentioned conventional dust collector, the resistance to the permeation force of air for dust collection increases as the amount of accumulated dust increases. This resistance reduces the ability to collect dust. Therefore, although the accumulated dust amount exhibits a high dust collecting force in the early stage of operation, the dust collecting force decreases as the dust is accumulated. As a result, in reality, at present, during a considerably long period during the operation period, the dust collecting force is much lower than the initial dust collecting force. As described above, the conventional dust collector has a problem that the original dust collecting force cannot be sufficiently exhibited.

[0004] It is an object of the present invention to provide a dust collector in which the operating force is hardly affected by the amount of dust collected.

[0005]

In order to achieve the above object, a dust collector according to the present invention comprises a filter for filtering dust in air containing dust, and a filter installed below the filter to filter the dust. A dust accumulation chamber that accumulates, and an inclined portion that forms an inclination with respect to dust falling from the filter and guides the dust to the dust accumulation chamber,
It has a shutter that opens and closes ventilation between the inclined part and the dust storage chamber, and a blower part that supplies and exhausts air, and interlocks the intake and exhaust operation of the blower part and the opening and closing operation of the shutter. I have.

Further, the above dust collecting apparatus further has a vibrating section for applying vibration to the filter, and the vibrating section removes dust adhering to the filter, so that the outer shape of the filter is conical, cylindrical or cylindrical. The filter may be of a hemispherical type, and the dust adhering to the surface of the filter may be removed, and at the same time, the dust may be collected in a dust storage chamber by an exhaust flow, and the dust collected in the dust storage chamber may be compressed by an exhaust force.

133 are configured.

The blower section 14 includes a pipe section 141 and a motor section 142. The blower section 14 is configured so that the direction of the ventilation pressure is reversible and the air flow of suction and exhaust can be selectively formed. The pipe section 141 is a cylindrical body that guides an air flow between the filter section 12 and the blower section 14. The motor section 142 generates the reversible supply / exhaust force by the rotational force. As a driving power supply to the motor unit 142 that generates the supply / exhaust power, a commercial power supply is supplied by a power cord (not shown), or a power supply supplied from a battery integrally formed with the dust collection device 10 is used.

In the dust collecting apparatus 10 configured as described above, a dust collecting function is formed when the blower unit 14 generates the suction force, and a dust storing function is formed when the exhaust force is generated. The operation procedure of the dust collector of the present embodiment based on this relationship will be described in detail below.

Symbols A to E in FIG. 1 indicate the directions of the air flow. When the blower unit 14 is generating the suction force, the directions of the air flows are indicated by symbols A and B. Further, in the case of the exhaust flow, symbols CE are shown. Note that the relationship between the intake and exhaust and the opening and closing of the two shutters 114 and 133 is such that when the intake air flows,
Shutter (1) 114 is open, shutter (2) 133
Is closed. At the time of exhaust, the shutter (1) 114
Is closed, and the shutter (2) 133 is opened.

(A) In the air flow in the directions of the symbols A and B, the high-speed air containing dust enters the inside of the dust collector 10 through the nozzle. Dust contained in the air that has entered inside is filtered by the filter unit 12. Among the filtered dust, heavy dust falls through the inclined portion or directly to the dust storage portion 13 due to the natural fall of gravity. Light dust adheres to the outer peripheral surface of the candle-shaped cylindrical filter 121. The filtered air passes through the filter 121,
Flows toward the main motor through the inside of the motor.

(B): After performing the dust collection operation by the suction operation (a), the dust accumulation operation is executed. This dust accumulation operation is performed by the operation of the small motor 122 and the exhaust operation of the blower unit. The dust adhering to the surface of the filter 121 is separated by the rotation of the small motor 122, and at the same time, the dust is collected in the dust storage chamber 132 by the exhaust flows C, D, and E. The dust collected in the dust storage chamber 132 is compressed by the exhaust power.

(C) In the operation from (a) to (b), the operation of the shutter (1) 114 starts with the shutter (1) 114 being closed, the opening of the shutter (2) 133, and the opening of the filter 121. The rotation is started, the rotation of the filter 121 is stopped, and after a few seconds, the shutter (1) 114 is opened, and the shutter (2) 133 is closed. Filter 12
After one rotation, the rotation of the main motor 142 is also stopped. In the present embodiment, all of these series of operations are completed in about 20 seconds.

(D) The dust storage chamber 132 is a cylindrical vessel, and its side and bottom are made of a strong frame and special fibers for transmission. Change over once every two or three months, considering the amount of accumulated dust. Alternatively, the accumulated dust is removed.

(E) The cleaner 151 is provided with the filter 12
1 is a brush-like device that is used about once every six months to prevent the dust collection function from being deteriorated due to long-term use. When the filter 121 is rotating, it is manually moved up and down to remove fine dust on the surface of the filter 121.

(Modification Example of First Embodiment) This modification example is a case where the filtering section is formed in a hemispherical shape.
4 and 5 show the configuration of the filter unit.

(A); High-speed air containing dust enters through the cylindrical nozzle portion 11. Heavy dust falls directly into the dust storage unit 13, and light dust falls on the hemispherical filter 221.
The air which has adhered to the outside and has passed through the filter 221 flows in the direction of the main motor 142.

(B): After stopping the driving of the main motor 142 (after the cleaning is completed), the small motor 122 is operated,
The ring 222 with the protrusion is rotated by the circuit,
Vibration is given to the filter 221 by a contact action with the projection 223 provided on the filter 221. At the same time, the main motor 142 is reversely rotated to change the air from the intake direction to the exhaust direction. Due to the wind pressure and the vibration, the filter 221
The dust adhering to the surface is separated from the surface, falls, and is collected in the dust storage unit 13.

The subsequent operation is the same as in the first embodiment.

<Second Embodiment> A second embodiment is a case of a canister type vacuum cleaner. FIG. 6 shows the overall configuration of the second embodiment. Nozzle part 31, filter part 32,
It is composed of each part of the blower unit 34, and the basic configuration and operation are the same as those of the first embodiment.

(Modification Example of Second Embodiment) This modification example is as follows.
This is the case where the filter unit 42 is hemispherical. FIG. 7 shows the overall configuration of this variation. This modification is different from the second embodiment in that the filter unit 32 of the second embodiment has a conical shape.
Other configurations and operations are the same as those of the second embodiment.

<Third Embodiment> The third embodiment is directed to a blackboard wiping cleaner. FIG. 8 shows the overall configuration of the third embodiment. It is composed of an intake port 51, a filter section 52, and a blower section 54. The basic configuration and operation are as follows.
This is the same as the first and second embodiments.

The above embodiment is a preferred embodiment of the present invention, but the present invention is not limited to this embodiment, and various modifications can be made without departing from the gist of the present invention. For example, in each of the above-described embodiments and variations, the rotational force of the motor is used to separate and separate dust adhering to the filter. However, this is not limited to the rotational force, and an exciting force such as a vertical vibration, a horizontal vibration, or the like may be used.

[0029]

As is clear from the above description, the dust collecting apparatus of the present invention guides the filtered dust in the dust-containing air to the dust storage chamber, and interposes between the inclined portion and the dust storage chamber. A shutter for opening and closing the ventilation is provided, and the intake / exhaust operation of the blower unit and the opening / closing operation of the shutter are linked. This makes it difficult for the collected dust to constitute the resistance of the air passing through the filter unit, and the dust collected in the dust storage chamber is compressed by the exhaust force, so that the dust collection force is hardly reduced.
