Description

Air conditioner indoor unit and filter screen cleaning method Technical Field The invention relates to the technical field of air conditioners, in particular to an air conditioner indoor unit and a filter screen cleaning method. Background After the indoor unit of the air conditioner is used for a long time, the windward side of the filter screen is converged to form certain dust, if the dust is not cleaned timely, the filter screen is blocked to cause unsmooth air intake, the effective air intake area of the air intake is reduced, and then the energy consumption of the air conditioner is increased, the refrigerating and heating effects are seriously affected, and excessive dust is accumulated on the surface of the filter screen, so that bacteria are easy to breed, secondary pollution of indoor air is caused, and the quality of the indoor air is affected. At present, the common filter screen cleaning mode is manual unpick and wash, and a consumer is required to reinstall after washing, which is time-consuming and labor-consuming and brings inconvenience to the user. In the related art, the filter screen is cleaned by arranging the automatic cleaning mechanism in the indoor unit of the air conditioner, but the automatic cleaning mechanism removes dust by virtue of the hairbrush, and the hairbrush is not easy to brush dust with certain viscosity, so that the cleaning effect is not ideal. Disclosure of Invention In order to overcome the problem of unsatisfactory cleaning effect caused by cleaning the filter screen by the brush in the related art, the first aspect of the present invention provides an indoor unit of an air conditioner, which comprises: The device comprises a shell, a front panel and a rear panel, wherein the shell is provided with an air inlet, a top rail extending along the width direction of the shell is arranged at a position corresponding to the air inlet in the shell; the indoor heat exchanger is arranged in the shell and is used for exchanging heat for air flow entering the shell through the air inlet, and an installation space is formed between the indoor heat exchanger and the front panel; The dust removing assembly is arranged in the installation space and is provided with a side rail extending along the height direction of the shell, and the side rail is communicated with the top rail; The filter screen is movably arranged in a filter screen channel, and the filter screen channel comprises a side rail and a top rail; The cleaning mechanism is arranged in the shell and comprises a filter screen flushing assembly, the filter screen flushing assembly comprises a barrel, the barrel is arranged between the top rail and the side rail, a connecting rail is formed on the periphery of the barrel, the top rail, the connecting rail and the side rail are communicated to form a filter screen channel, a water spraying hole is formed in the barrel wall of the barrel, and the water spraying hole is communicated with the inner cavity of the barrel; When the water is supplied to the cylinder, the water in the cylinder can be sprayed out through the water spraying holes to flush the filter screen in a moving state. According to the indoor unit of the air conditioner, high-pressure water flow can be sprayed to the filter screen through the filter screen washing component, dust adhered to the filter screen is separated from the filter screen under the action of the high-pressure water flow, and the cleaning effect of the filter screen is improved. And through washing the filter screen with filter track and the ingenious combination of top track connected barrel, can realize washing the filter screen from the dorsal part of filter screen, more easily wash down the dust that attaches to on the filter screen to simple structure, low in production cost is convenient for mass production. In some embodiments, the cylinder is fixed between the top rail and the side rail, the outer circumferential surface of the cylinder has a connection cambered surface connected with the top rail and the side rail, and the water spraying hole is formed in the connection cambered surface. According to the air conditioner indoor unit of the embodiment, the water spraying holes are formed in the connecting cambered surface, so that the water spraying holes can be reduced while the flushing effect of the filter screen is guaranteed, the water sprayed out of the filter screen by the cylinder is avoided, and the water is saved. In some embodiments, the plurality of water spraying holes are distributed along the length direction and/or the circumferential direction of the connecting cambered surface. According to the indoor unit of the air conditioner, the water spray holes are distributed along the length direction and/or the circumferential direction of the connecting cambered surface, so that the filter screen can be comprehensively washed and cleaned in the length direction, and the cleaning effect is ensured. In some embodiments,
