Description

Air Conditioner {AIR CONDITIONER}

The present invention relates to an air conditioner, and more particularly, to an air conditioner having an automatic cleaning function of an air filter.

In the air conditioner, the indoor air sucked by the blower fan is cooled or heated by passing through a heat exchanger to return to the room, but in order to prevent dust floating in the room from contaminating the heat exchanger, An air filter is installed on the front side. When dust adheres to this filter, filler clogging occurs and the ventilation resistance increases, the air conditioner of the air conditioner decreases, and power consumption increases. In order to eliminate such inadequacies, various air conditioners with automatic cleaning devices for filters have been proposed.

In order to clean a filter automatically, there exists a method disclosed by Unexamined-Japanese-Patent No. 62-145019 (JP62-145019U). In this method, the band-shaped filter formed in an annular shape is supported by a pair of rollers, and the band-shaped filter is moved by rotating the roller with a motor, and the filter is cleaned with a rotating cleaning brush in the process. do. Moreover, as a method of moving a filter, as shown in JP 2001-99479A (JP2001-99479A), the band-shaped filter wound around one roller is moved to the other roller, and in the process You can also clean with a cleaning brush. In this case, after cleaning, the filter is rewound from the other roller to the one roller.

In the case of JP62-145019U, the dust removed from the filter is collected in a dust box (dust collecting place) disposed at the front or the bottom of the cleaning brush, and when it is filled, or periodically by suction by a vacuum cleaner or the like. Clean. In addition, in JP62-145019U, the dust box is detachably attached to the air conditioner main body, and the dust box is detached from the air conditioner main body so that cleaning and washing can be performed. However, since the cleaning brush is connected to the drive motor, it cannot be removed from the air conditioner body.

In the air conditioner of JP62-145019U, when the dust box is removed from the main body side, there is a problem that the collected dust is easily scattered.
