In some embodiments, as shown in fig. 1 and 2, the water receiving tray 162 is disposed on the bottom plate, the water receiving tray 162 is disposed at a position inclined from the front to the back, and the water receiving tray 162 is located above the bottom plate 142 and spaced apart from the bottom plate 142. Wherein, the periphery of the water pan 162 is a vertical wall surface, so as to form a cavity for containing water, the water pan 162 is arranged, and the first water receiving section 1621 of the water pan 162 is arranged below the evaporation heat exchanger 109, thereby collecting the condensed water generated by the evaporation heat exchanger 109 when the air conditioner refrigerates, avoiding the condensed water from directly flowing onto the bottom plate 142, and a certain distance exists between the water pan 162 and the bottom plate 142, such as 0.5cm to 5cm, so that an air space exists between the water pan 162 and the bottom plate 142, thereby preventing the low temperature of the condensed water on the water pan 162 from being transferred onto the bottom plate 142, and preventing the temperature of the bottom plate 142 from being reduced to generate condensation phenomenon, even if the condensation is generated on the outer surface of the water pan 162, the water quantity of small water drops generated by the condensation is much less than that of the condensed water, even if the water drops onto the bottom plate 142, the very small water drops can be evaporated by the bottom plate 142 with relatively high temperature, without a substantial decrease in the temperature of the bottom plate 142. And the water pan 162 is arranged to incline from the front side of the evaporation heat exchanger 109 to the rear side of the condensation heat exchanger 106, so that condensed water dropping from the evaporation heat exchanger 109 can be quickly drained away by the water pan 162, and can not be accumulated at the position of the first water receiving section 1621 to cause an overflow phenomenon.

The water pan comprises a first water receiving section arranged below the evaporation heat exchanger, and a second water receiving section arranged below a refrigerant pipeline, wherein the refrigerant pipeline is a pipeline connecting a gas suction pipe of the compressor 107 to the evaporation heat exchanger 109, and is specifically a refrigerant pipe connecting section 164 shown in fig. 2. The refrigerant pipe from the exhaust port of the compressor 107 is a high-temperature high-pressure gaseous refrigerant, which is cooled by the condensing heat exchanger 106 after discharging heat to the outside, and then is changed into a low-temperature high-pressure liquid refrigerant, and is throttled and reduced in pressure by a throttling pressure reduction component such as a capillary tube 163 to become a medium-temperature high-pressure liquid refrigerant with a slightly lower temperature, and then enters the evaporating heat exchanger 109, and then the evaporating heat exchanger 109 absorbs heat to the surrounding environment to reduce the temperature, and the temperature of the refrigerant is increased, while the temperature in the refrigerant pipe penetrating through the evaporating heat exchanger 109 is very low, so that the temperature of the fins of the evaporating heat exchanger 109 installed on the refrigerant pipe is also very low, thereby generating condensed water which drops to the first water receiving section of the water receiving tray 162 below the evaporating heat exchanger 109, and then is changed into a low-temperature gaseous refrigerant after coming out of the evaporating heat exchanger 109, and finally enters the suction, and the process is circulated. Therefore, the refrigerant pipe connecting the inlet and the outlet of the evaporating heat exchanger 109 absorbs heat to the outside, so that the temperature of the refrigerant pipe is low, generally lower than 2 °, and therefore condensed water is easily generated in the refrigerant pipe, particularly, the refrigerant pipe connecting section 164, which is the refrigerant pipe connecting the suction port of the compressor 107, and the refrigerant pipe connecting the evaporating heat exchanger 109 and the condensing heat exchanger 106, is mainly a capillary tube 163, and the pipe diameter thereof is much smaller than that of the refrigerant pipe at other positions, so that much less condensed water is generated and the condensed water is not easily dropped. Therefore, it is preferable to dispose the refrigerant pipe connecting section 164, which is a refrigerant pipe connected to the suction port of the compressor 107, above the water receiving tray 162, i.e., above the second water receiving section, so as to receive the dropped condensed water. Furthermore, a section of refrigerant pipe, i.e., the capillary tube 163, connecting the evaporating heat exchanger 109 and the condensing heat exchanger 106 may also be disposed above the second water receiving section, so as to reduce the phenomenon that the generated condensed water drops on the water receiving tray 162.
