Self-cleaning filter screen and air conditioner

Abstract

The invention discloses a self-cleaning filter screen and an air conditioner, and relates to the technical field of air conditioner self-cleaning. The self-cleaning filter screen comprises a metal net, an insulating frame, an N-type semiconductor, a P-type semiconductor and a direct current power supply device, the metal net is arranged on the inner ring of the insulating frame, and one end of themetal net is connected with the insulating frame through the N-type semiconductor; and the end, away from the N-type semiconductor, of the metal net is connected with the insulating frame through theP-type semiconductor, the positive electrode of the direct current power supply device is electrically connected with the P-type semiconductor, and the negative electrode of the direct current powersupply device is electrically connected with the N-type semiconductor. The air conditioner comprises an indoor unit, a filter screen is arranged in the indoor unit, and the self-cleaning filter screenis adopted as the filter screen. The self-cleaning filter screen can automatically cool, frost, heat and defrost without disassembly or use of an electric heater, so that the cleaning is simple, convenient and quick; and the air conditioner uses the self-cleaning filter screen, maintenance is convenient, the refrigerating or heating effect is prevented from being reduced, and the user experienceis improved.

Description

technical field [0001] The invention relates to the technical field of air conditioner self-cleaning, in particular to a self-cleaning filter screen and an air conditioner. Background technique [0002] The air conditioner purifies the air mainly by using a filter to filter the air to achieve the effect of sterilization and dust removal. However, after using the air conditioner for a long time, dust will appear on the surface of the filter. The accumulation of dust not only affects the use effect of the filter, but also causes the air inlet to be blocked, affecting the air intake, resulting in poor cooling and heating effects. [0003] When cleaning the filter screen, there are usually two ways. The first is to maintain the cleanliness of the filter screen by manually disassembling the filter screen and cleaning it manually. The second is to install an electric heater in the evaporator, and then adjust the air conditioner to the cooling state, so that the surface of the eva...

Problems solved by technology

[0004] For the first method, for the split wall-mounted unit, the indoor unit has a certain installation height requirement, and the user needs to climb up to remove and clean the filter screen, which is extremely inconvenient

For the cabinet machine, in order to achieve the purpose of aesthetics, the filter is hidden in the casing, and the user needs to install the air conditioner casing to remove the filter, which is not easy to operate

For the second method, the electric heater has a large volume, which not only blocks the incoming air, but also blocks the outgoing air, thereby reducing the cooling and heating effects
