Detailed Description of the Invention

[0001]

The present invention is used in a place where a large amount of dust is generated, such as a construction site, a building dismantling site and an asbestos removal site, or a place where extremely minute dust must be removed. The present invention relates to a dust collector, and more particularly to an excellent high-speed dust collector which has extremely excellent dust collecting ability and can perform the clogging removal work of a filter which has conventionally required manual labor without requiring human labor.

[0002]

2. Description of the Related Art Conventionally, as a portable dust collector, air is taken in from a suction port by driving a rotary blade, and this air is guided in one direction toward the position of the filter and filtered by the filter. When the filter is clogged with dust and the dust collection capability is reduced, the user stops the dust collector, removes the filter, performs cleaning work, stores the filter in the dust collector again, and starts the dust collector. Was there.

[0003]

However, in the above-mentioned conventional dust collector, since the air flow path from the air suction port to the filter, the rotary blades to the air discharge port has a narrow tubular shape, The air flow rate per unit time was small and therefore the dust collection ability was also poor. Enlarging the entire air flow path to increase the dust collecting capability leads to an increase in the size of the device, which is far from the intention of the consumer who desires a compact dust collector having excellent portability. . In addition, in the work of removing clogging of the filter in the conventional dust collector, the work efficiency of the site work is reduced because the work of the site work such as construction work, dismantling work and asbestos removal work is troublesome. It was something that caused it.

In view of the above, the present invention has a small form, is excellent in portability, and can exhibit a great dust collecting capability.
It is an object of the present invention to provide a fully-automatic high-speed dust collector that can eliminate clogging of a filter without requiring any human intervention.

[0005]

In order to achieve the above-mentioned object, a high speed dust collector according to the present invention has an air inlet in a plurality of side directions and a door member for freely opening and closing the air inlet and has an upper end. An outer casing having an opening as an opening, a substantially cylindrical filter disposed inside the outer casing and spaced apart from the inner peripheral surface of the outer casing and having an upper portion as an opening end, A sensor for detecting a clogging condition of dust, a bidirectional rotatable rotor provided at the open end of the filter,
It is composed of a dust container that can be freely taken out from the outer casing located at the lower part of the filter, and when collecting dust in the air, the rotary blade rotates in the forward direction and opens. When air is taken in from the air intake port and permeates the filter to attach dust in the air to the filter, and when the sensor detects a clogging state of the filter, the door member closes the air intake port. The rotary blades rotate in the opposite direction, and the air sucked from the opening at the upper end of the enclosure is jetted from the inside to the outside of the filter to store the dust attached to the filter in the dust container. It is characterized by doing.

[0006]

The air suction ports are formed in a plurality of directions on the side surface of the outer casing, and a substantially cylindrical filter is disposed inside the outer casing so as to be spaced apart from each other. By arranging the rotor blades, the air sucked from the air suction port by rotating the rotor blades in the forward direction is substantially swirling while rotating in a space between the inner peripheral surface of the outer casing and the filter. It is evenly filtered over the entire circumference of the cylindrical filter. By installing a door member that freely opens and closes the air intake port, a sensor that detects the clogging state of the filter is installed, and by further enabling the rotor to rotate in both directions, The door member closes the air intake port, and then rotates the rotary blade in the opposite direction, so that air can be jetted from the inside to the outside of the clogged filter to remove dust attached to the filter. Further, after performing the operation of removing the clogging state of the filter for a predetermined time, the dust collection work is automatically performed again, so that the user does not have to perform maintenance work to clear the clogging of the filter. It becomes possible to perform dust collection work. By making the inner peripheral surface of the outer enclosure mirror-like, the outer enclosure falls and is housed in the dust container without dust being attached.
