technical field

The present invention relates to an air conditioner provided with a function of automatically cleaning an air filter provided at an air suction port of an indoor unit.

Background technique

Conventional air conditioners, as shown in Figures 28 and 29, are provided with an air filter 6 for preventing dust from entering the inside of the main body 13 in front of the heat exchanger 11, and the air filter 6 is detachably configured so that The attached dust can be cleaned by hand.

Moreover, as an air conditioner that is easy to clean the air filter, it is provided with: a rotating brush; a brush cover that rotatably supports the rotating brush and covers the rotating brush; and a filter brush that is coaxial with the rotating brush. The suction nozzle of the electric vacuum cleaner is connected to the suction port provided on the brush cover, and moves on the air filter, and sucks while scraping off the dust accumulated on the air filter (for example, refer to Patent Document 1).

Moreover, the following proposals have been proposed: a collection device, a cleaning device, a suction mechanism, a load beam connected to the suction mechanism, a hose connected to the load beam, a vacuum generator, and a separator arranged on the suction side of the vacuum generator Such configurations automatically suck the dust adhering to the air filter, and collect the dust by the separator (for example, refer to Patent Document 2).

Furthermore, there is also a proposal that includes a driving shaft and a driven shaft on which a belt-shaped air filter is mounted, a servo motor for driving the driving shaft, a brush, a dust sensor and a fan arranged on the exhaust pipe, and a calculated air filter.
