The wind wheel 14 in the second cavity rotates to generate suction and sucks external fresh air into the second cavity through the fresh air inlet. Then the air conditioner blows the fresh air into the room to ventilate the room. The fresh air inlet can be opened selectively. When the filter 12 is removing dust, the fresh air inlet is closed. After the filter 12 is finished removing dust, the fresh air inlet is opened, and the wind wheel 14 rotates to produce fresh air.

[0070] According to one embodiment of the present invention, the filter dust removal device 1 also includes a first valve 181 and a second valve 182. The first valve 181 is arranged in the fresh air housing 13 to selectively connect or close the fresh air inlet to the second cavity; the second valve 182 is arranged in the first cavity and can selectively connect or close the first cavity to the dust removal port 111.

[0071] Specifically, a first valve 181 is provided on the fresh air housing 13, and the first valve 181 can be turned on or off under the drive of the driving motor 151, so as to selectively turn on or off the fresh air inlet and the second cavity; a second valve 182 is provided in the first cavity, and the second valve 182 can be turned on or off under the drive of the driving motor 151, so as to control the conduction or closure of the first cavity and the dust removal port 111, wherein, when the air conditioner is on standby for a predetermined time or when the user actively sets the air conditioner to start dust removal of the filter 12, the second valve 182 is turned on or off. The first valve 181 is closed, the second valve 182 is opened, and the filter 12 moves along the first track 1131 and the second track 1122 driven by the driving member. After the filter 12 passes through the dust removal port 111, the dust on the filter 12 is sucked into the dust box 171 by the suction force generated by the rotation of the wind wheel 14. When the filter 12 is dusted, the first valve 181 is opened, the second valve 182 is closed, the second cavity is connected to the fresh air inlet, and the wind wheel 14 rotates to generate suction to suck the external air into the wind wheel cavity 131, and then generates fresh air for the room. The present application sets the first valve 181 and the second valve 182 to ensure that the filter 12 is dusted and generates fresh air alternately, and the air conditioner automatically removes dust from the filter 12, thereby improving the user experience.

[0072] According to one embodiment of the present invention, the filter bracket 11 is located at the top of the fresh air housing 13, and the dust removal port 111 is located at the bottom of the filter bracket 11; the partition 16 is formed with a guide slope 161 which is opposite to the dust removal port 111 in the height direction, and the guide slope 161 is inclined toward the dust collection box 171 in the direction away from the dust removal port 111.
