Referring to fig. 1 to 3, an embodiment of the present invention is shown for an air conditioner indoor unit without water and self-cleaning. As shown in the figure, the waterless self-cleaning air conditioner indoor unit comprises a water storage mechanism 1 and a water spraying mechanism; the water storage mechanism 1 is communicated with a bottom shell water channel 2 of an air conditioner indoor unit, and condensed water condensed on an evaporator 3 flows into the water storage mechanism 1 along the bottom shell water channel 2 for storage when the air conditioner works; the water spraying mechanism comprises a water feeding device 4 and a spraying device 5 connected with the water feeding device, the water feeding device 4 is arranged at the bottom in the water storage mechanism 1, and the spraying device 5 is arranged below the evaporator 3 and is positioned above a cross-flow fan blade 6 and an inner air duct 7 of an air conditioner indoor unit; when the air conditioning equipment is started in a self-cleaning indoor unit mode, the water conveying device 4 conveys condensed water stored in the water storage mechanism 1 to the spraying device 5, the spraying device 5 sprays the condensed water to the cross-flow fan blade 6 and the inner air duct 7, and the water-free self-cleaning function of the air conditioning indoor unit is realized by matching with the rotation of the cross-flow fan blade 6 and the working of the evaporator 3 in a heating or cooling mode. Specifically, in an embodiment, when an air conditioning device starts a self-cleaning indoor unit mode, the water feeding device 4 conveys condensed water stored in the water storage mechanism 1 to the spraying device 5, the spraying device 5 sprays the condensed water to the cross-flow fan blade 6 and the inner air duct 7, the air conditioning indoor unit drives the cross-flow fan blade 6 to operate at a low speed, the evaporator 3 starts a refrigeration mode, the cross-flow fan blade 6 and the inner air duct 7 are uniformly wetted by water mist and then begin to be cooled and frosted, then the evaporator 3 starts a heating mode to enable the cross-flow fan blade 6 to begin to melt frost and take away dirt, at this time, the spraying device 5 continues to spray the condensed water to the cross-flow fan blade 6 and the inner air duct 7 for cleaning, after cleaning, the spraying device 5 stops spraying the condensed water, and the evaporator 3 continues to operate a heating program to dry the inner air duct 7 and the cross-flow fan blade 6, so that self-cleaning of the cross-flow fan blade 6 and the inner air duct 7 is completed.
It should be noted that when the air conditioning equipment normally works, the water storage mechanism 1 is in a water storage state, and water used for cleaning the cross-flow fan 6 and the internal air duct 7 comes from condensed water collected by the water storage mechanism 1, so that the air conditioning equipment is called as a waterless self-cleaning air conditioner internal unit. When the water storage mechanism 1 is lack of water, water can be added into the water storage mechanism 1 in a manual water adding mode.
Furthermore, it should be noted that the waterless self-cleaning air conditioner indoor unit further has a humidification function, and when the water amount in the water storage mechanism 1 is sufficient, the humidification mode can be started. Because the spraying device 5 of the anhydrous self-cleaning air conditioner indoor unit is arranged below the evaporator 3, namely, the humidified air does not need to pass through the evaporator 3, the humidification effect can be ensured, and the humidification effect can be further improved by using the cross-flow fan blade 6 to carry out forced convection.
