[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of an impeller having a dust collecting function used in an air cleaner.

[0002]

[Prior art]

 Conventionally, a disk-shaped fan-combined filter made of a felt-like substance fixed to a shaft of a motor and an impeller having a structure in which a centrifugal fan is fixed to the filter are disclosed in Japanese Utility Model Publication No. 48-7746 (hereinafter The former), and an impeller in which a plurality of fan blades constituting a centrifugal fan are radially sandwiched and fixed between two disc-shaped fan / filters made of felt-like material. It is known from Japanese Patent Publication No. 48-7745 (hereinafter referred to as the latter).

[0003]

[Problems to be solved by the device]

 However, in the former impeller, since the filter that also serves as the fan is the main plate of the impeller, the contaminated air only flows along the surface of the filter that also serves as the fan, and the problem that the dust collection efficiency due to passage is low is a problem to be solved. In the latter impeller, the contaminated air passes through one of the two fan / filters, but the other one fan / filter only flows along the surface, so compared to the former. Although the dust collection efficiency is high, the clogging of the first filter that also serves as a fan blocks the passage of contaminated air, which poses a problem in that the suction and transfer capacity is reduced.

An object of the present invention is to provide an impeller for an air purifier that effectively improves the dust collection effect by effectively passing or contacting contaminated air, and does not reduce the suction and conveyance ability. .

[0005]

[Means for Solving the Problems]

 The present invention has been made to solve the above-mentioned problems, and it is provided between a main disk having a boss fixed to the shaft of a motor in the center and a sub disk having an intake port opened in the center. In an impeller provided with a large number of blades that guide the air flowing in from the intake port in the circumferential direction and send it out, the blades are sandwiched by a reinforcing member made of a ventilation member made of a porous material having air permeability. The impeller for the rotating air cleaner, which is characterized in that it is configured to reinforce, a fixing sub-disk having a through hole for the motor shaft to pass through in the center, and an air supply port in the center. In an impeller provided with a large number of blades for delivering air guided from a circumferential opening from the air supply opening to the established main disc for fixation, the blade is made of a porous material having air permeability. It is configured to be strengthened by sandwiching the Are summarized as air purifiers impeller secured to a portion of the casing used in conjunction with air cleaner for an impeller which rotates, characterized in that.

[0006]

[Action]

 The impeller for an air purifier configured as described above has a filter function to remove contaminated air smoothly sucked from the intake port without any resistance when the impeller is fixed to the motor shaft and rotated. When it is sent out in the circumferential direction by the blade, or when it is fixed to a casing or the like to guide the air, it passes through the blades when sending the air guided from the circumferential opening from the air supply port. It comes into contact with the blades and blades, and acts to improve the dust collection effect without deteriorating the suction and conveyance ability.
