[0002] The filter is an important air filtering mechanism in the air conditioner. Its main function is to filter dust particles in the air and also to prevent insects from entering the air duct.

[0003] Dust particles generally cover the filter, but due to the continuous use of the air conditioner, the dust layer on the filter continues to thicken. When the air conditioner is stopped, the dust will fall off due to gravity and contaminate the inner surface of the panel or the inner surface of the middle frame. Dust may also get stuck in the gap between the panel and the middle frame. The above problems cause users or after-sales service to open the panel when they want to clean the filter, and dust falls on their faces, resulting in poor user experience and customer complaints.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an electrostatic adsorption dust filter, including a dust filter frame, a filter fixed on the dust filter frame, the filter covering the holes on the dust filter frame, a conductor embedded in the dust filter frame, the conductor covering the holes on the dust filter frame, electrical contacts installed on the conductor, a dust collecting groove is provided on the dust filter frame, the opening of the dust collecting groove faces the inside of the dust filter frame, part of the dust collecting groove is located below the filter, the dust collecting groove is located in front of the filter, and the dust collecting groove is located in front of the conductor.

[0006] Preferably, the electrical conductor comprises a copper sheet.

[0007] Preferably, the dust filter frame and the conductor are integrally injection molded.

[0008] Preferably, a forward-facing slot is provided on the inner wall of the dust collecting tank, and the conductor is exposed from the slot.

[0009] Preferably, crisscross ribs are installed in the dust filter frame.

[0010] Preferably, the electrical contacts are located on the back of the dust filter frame.

[0011] Preferably, the two electrical contacts are respectively arranged on the left and right sides of the dust filter frame.

[0012] An air conditioner comprises the above-mentioned electrostatic adsorption dust collection filter.

[0013] Preferably, the electrostatic adsorption dust filter is installed on the middle frame; the middle frame is provided with a mounting groove opening forward, a vent is provided in the mounting groove, the electrostatic adsorption dust filter is installed in the mounting groove by means of a buckle, and the filter blocks the vent.

[0014] Preferably, two sets of electrostatic adsorption dust filters are installed on the middle frame.

[0015] The beneficial effect of the technical solution of the utility model is that after the electric body is energized, a weak electric field is formed on its inner side to wrap the filter, so that dust can still be prevented from entering the air duct of the indoor unit of the air conditioner when the air conditioner is not working, thereby ensuring the air quality when the air conditioner is started, and after the dust falls off the filter, it will be directly caught by the integration at the bottom of the dust filter frame, and will not fall directly out of the indoor unit, thereby improving the user's functional experience.
