[0033] In this way, the water receiving tray of the present invention solves the problem in the prior art that the condensed water in the air conditioner fails to be discharged in time due to the dust blockage of the condensed water pipe, and even the phenomenon of the backflow of condensed water occurs, preventing the water flow from entering the room and wetting the wall and floor, and even damaging the furniture, and preventing the phenomenon that the bacteria in the condensed water enter the room and endanger human health, improving the user comfort experience. In addition, the receiving cavity 23 can be longitudinally compressed and expanded, and can maintain a certain degree of relaxation when the drain pipe is not blocked. Within a certain limit, the volume of the receiving cavity 23 can increase with the increase of the internal condensed water within a certain limit to accommodate enough condensed water.

[0036] The water receiving tray of the present invention includes a driving component 60, and the driving component 60 is connected to at least one of the upper water receiving part 11 and the lower water receiving part 21 to drive the upper water receiving part 11 and the lower water receiving part 21 to move closer to or away from each other.

[0037] As Figures 1 to 3 shown, the driving component 60 includes a plurality of screw rods 61. Among them, each screw rod 61 is rotatably connected to the upper water receiving part 11, and each screw rod 61 is threadedly connected to the lower water receiving part 21 to drive the lower water receiving part 21 to move in a direction close to or away from the upper water receiving part 11 by rotating the plurality of screw rods 61; or each screw rod 61 is rotatably connected to the lower water receiving part 21, and each screw rod 61 is threadedly connected to the upper water receiving part 11 to drive the upper water receiving part 11 to move in a direction close to or away from the lower water receiving part 21 by rotating the plurality of screw rods 61.

[0046] The water receiving tray control method of the present invention is specifically as follows:

[0047] When the real-time water level H in the accommodating cavity 23 where the float 40 is located is greater than or equal to the preset water level H0, the float 40 will contact the limit switch 50 to turn on the limit switch 50, so as to control the air conditioner to turn off to prevent condensed water from overflowing, the control switch part 12 closes the opening part, and controls the driving motor to drive the screw rod 61 to move so that the distance between the upper water receiving part 11 and the lower water receiving part 21 is L0, so as to force the drain pipe to be dredged;
