[0003] The core structure of air conditioner usually includes heat exchanger, air duct and water pan and other components. In the running process, air needs to pass through the heat exchanger to complete heat exchange, and then is transported to indoor through the air duct. Because the surface temperature of heat exchanger is low, the moisture in the air is easy to condense to form condensate water. In order to ensure that the condensate water can be smoothly discharged, the water pan is used to receive and discharge these condensate water, so as to prevent the condensate water from dropping to the internal elements of air conditioner and avoid equipment failure or damage.

[0004] However, in the prior art, there is usually an assembly gap between the water pan and the air duct, which not only affects the heat exchange efficiency, but also may cause a series of problems: (1) heat exchange efficiency decreases: air directly enters the air duct without passing through the heat exchanger, resulting in insufficient heat exchange and reducing the cooling or heating effect of air conditioner; (2) condensate water leakage risk: part of the condensate water may overflow due to assembly gap and cannot be completely introduced into the water pan, resulting in condensate water dripping to the internal electrical elements of air conditioner, which exists safety hazard; (3) shortening of service life of equipment: long-term condensate water leakage may cause corrosion or electrical failure of internal components of air conditioner, reducing the reliability and service life of equipment.

[0037] In the embodiment of the utility model, by setting sponge 30 between water pan 10 and air duct 20, air can be effectively prevented from entering air duct 20 directly through gap, so that air is fully contacted when passing through heat exchanger, improve the heat exchange efficiency of air conditioner, and then improve the refrigeration or heating effect of air conditioner, while sponge 30 can effectively prevent condensate from overflowing from water pan 10, ensure that condensate can smoothly enter water pan 10, and reduce the risk of water leakage, avoid damage to air conditioner internal structure or circuit, ensure the safety and long-term stable operation of equipment, ensure the use safety and reliability of air conditioner.

[0038] Specifically, in the embodiment of the utility model, the central water receiving area 12 includes the second side wall 13 close to the first side wall 11, the first side wall 11 and the second side wall 13 are formed with the supplementary water receiving area 15, when the condensate water in the air duct 20 flows through the matching position of the water receiving tray 10, most of the water will be blocked by the sponge 30 and directly flow into the central water receiving area 12, a small part will penetrate into the supplementary water receiving area 15 through the sponge 30, thus passing through the second side wall 13 and forming the supplementary water receiving area 15, the supplementary water receiving area 15 can play a storage and guiding role, thereby avoiding the condensate water from accumulating or leaking into the air conditioner, and ensuring the efficient operation of the condensate water treatment system.

[0039] Based on the above scheme, in the embodiment of the utility model, the water receiving tray 10 further has a drain port 14, the drain port 14 is arranged on the first side wall 11, and the drain port 14 communicates the central water receiving area 12 and the supplementary water receiving area 15, through the arrangement of the drain port 14, the condensate water can flow smoothly from the supplementary water receiving area 15 into the central water receiving area 12, thereby avoiding moisture accumulation, improving the drainage efficiency, reducing the possibility of water leakage, and thus facilitating the condensate water to be discharged from the air conditioner through the central water receiving area 12.

[0040] At the same time, in order to avoid the condensate water from being retained in the supplementary water receiving area 15 and ensure that the condensate water can flow smoothly into the central water receiving area 12, in the embodiment of the utility model, the drain port 14 is located at the lowest point of the supplementary water receiving area 15, since water naturally flows to the low point, the arrangement of the drain port 14 at the lowest point can realize the automatic guiding of the condensate water and improve the drainage effect.
