This air passes through the air passage 10 and the dust collection chamber 9 and flows into the air chamber 12. When the air flows from the dust collection chamber 9 into the air chamber 12, the dust contained in the air is removed by the filter 11, so that the air is further purified. Then, this air is discharged to the outside through the exhaust port 16. Therefore, the indoor air can be cleaned.

It should be noted that the dust collection station 1 is provided with a rotary drive mechanism for rotating the drive roller 45, and when the surface of the endless belt 47 exposed on the lower surface of the casing 44 is completely decharged, the rotary drive mechanism automatically operates. Alternatively, the surface of the endless belt 47 housed in the casing 44 may be unrolled so that the surface is decharged.

In the above embodiment, as the charging means for charging the cleaning body, the one that generates the ions by the corona discharge and charges the cleaning body by the ions is adopted. Alternatively, it is possible to adopt a structure in which the cleaning body is charged by slidingly contacting the insulating body with the cleaning body.

Further, in the above-described embodiment, as the charge eliminating means for eliminating the charge of the cleaning body, the one which generates the ions by the corona discharge and removes the charge of the cleaning body by the ions is adopted, but instead of this, It is also possible to adopt a device in which the cleaning member is destaticized by slidingly contacting the cleaning member with a grounded conductive member. In this case, as the conductive member, for example, a brush made of a material in which resin is impregnated with carbon can be used.

The microprocessor of the dust station compares this data with the reference value to determine whether charging or discharging has ended, and if it has finished, the microprocessor of the dust collecting station stops the charging means or discharging means. You may

In this case, if there is no change in the data output from the collector type potential detecting device detecting means within a predetermined time after the transmitting LED has transmitted the charging operation mode signal or the discharging operation mode signal, the transmitting LED is for transmission. You may make it stop transmission of the data to a dust collection station by LED.
