In particular, the heat exchanger 20 is formed of one heat exchange section 201, which facilitates production and assembly. Or the heat exchanger 20 may be constructed of a plurality of heat exchange sections 201, and the plurality of heat exchange sections 201 are overlapped with each other to form the complete heat exchanger 20. The heat exchanger 20 is formed by overlapping the heat exchange sections 201, so that the heat exchanger 20 can be conveniently installed or disassembled when the heat exchanger 20 is replaced or repaired. And the multistage structure can set up heat exchanger 20 of bigger area in certain space, satisfies the high heat transfer demand in narrow and small space, and overall structure is compacter.

It should be noted that the area size of the air inlet 15 affects the size of the air inlet area of the air conditioner 100, and thus affects the heat exchange efficiency of the heat exchanger 20 and the heat exchange capability of the air conditioner 100.

For example, in some embodiments, as shown in fig. 1-3, the front sidewall 13 extends vertically, and the air inlet 15 is disposed on the front sidewall 13; the lower side wall 12 extends in the transverse direction, and an air inlet 15 and an air outlet 16 are arranged on the lower side wall 12. The area of the air inlet 15 on the front side wall 13 is greater than or equal to 80% of the area of the front side wall 13, and the area of the air inlet 15 on the lower side wall 12 is greater than or equal to 40% of the area of the lower side wall 12, so as to ensure the air intake volume introduced from the air inlets 15 on the front side wall 13 and the lower side wall 12 in unit time, and further ensure the air inlet area of the air conditioner 100, thereby improving the heat exchange efficiency of the heat exchanger 20 and the heat exchange capacity of the air conditioner 100.

Specifically, the water chute 50 is arranged at one axial end of the wind wheel 60, and the water chute 50 is connected with the end parts of the first water pan 30 and the second water pan 40 in the length direction so as to communicate the first water pan 30 with the second water pan 40, so that on one hand, the interference between the water chute 50 and the wind wheel 60 is avoided; on the other hand, the overall structural strength of the first water pan 30, the second water pan 40 and the water chute 50 is improved.

In some embodiments, as shown in fig. 8 and 9, there are two water chutes 50, two water chutes 50 are used to communicate two ends of the first water receiving tray 30 and the second water receiving tray 40, the two water chutes 50 are respectively located at two axial sides of the wind wheel 60, so that the first water receiving tray 30, the second water receiving tray 40, and the two water chutes 50 form an annular frame surrounding the wind wheel 60, the structure is more stable, and the two water chutes 50 enable water flow of the first water receiving tray 30 and the second water receiving tray 40 to converge better.

Specifically, one end of the water chute 50 is connected to the first water receiving tray 30, the other end of the water chute 50 is connected to the second water receiving tray 40, and one end of the water chute 50 connected to the first water receiving tray 30 is higher than the other end of the water chute connected to the second water receiving tray 40, so that the condensed water in the first water receiving tray 30 flows into the second water receiving tray 40 through the water chute 50, and the condensed water collected in the second water receiving tray 40 is discharged to the outside through the water discharge structure 70 on the second water receiving tray 40. In other words, the first drain pan 30 and the second drain pan 40 drain water through the same drainage structure 70, which is advantageous for simplifying the structure.

Further, as shown in fig. 8 to 12, the lowest point of the first water receiving tray 30 is higher than the highest point of the second water receiving tray 40, and the height difference (as shown by H in fig. 11) is greater than 10mm, so that all the condensed water received in the first water receiving tray 30 is ensured to be collected into the second water receiving tray 40 through the water chute 50, and water accumulation in the first water receiving tray 30 is avoided.

In some embodiments, as shown in fig. 5 and 6, the drainage structure 70 includes: a drain tank 71 and a drain pump 72.

Wherein, the drain tank 71 is communicated with the second water pan 40; the suction pipe of the drain pump 72 extends into the drain tank 71 to discharge the liquid in the drain tank 71.

Specifically, the condensed water generated by the first heat exchanger 21 during operation flows into the first drip tray 30, the condensed water generated by the second heat exchanger 22 during operation flows into the second drip tray 40, the condensed water in the first drip tray 30 flows into the second drip tray 40 through the water guide groove 50, and the second drip tray 40 is communicated with the drain groove 71, so that the condensed water is collected in the second drip tray 40 and then flows into the drain groove 71. The drain pump 72 operates to pump out the condensed water and discharge the condensed water to the outside through the water pipe. The drainage of the condensed water in the drainage groove 71 is not influenced by factors such as installation environment, installation height, drainage pipeline position and the like, and the adaptability is stronger.

In some embodiments, as shown in fig. 5, the highest point of the drainage channel 71 is lower than the lowest point of the second drip tray 40 or is flush with the lowest point of the second drip tray 40, so as to ensure that the condensed water in the second drip tray 40 can be smoothly collected into the drainage channel 71, so that the drainage pump 72 can discharge the condensed water collected in the drainage channel 71 to the outside, and meanwhile, the excessive water in the second drip tray 40 can be prevented from overflowing into the interior of the housing 10.

Furthermore, the drain structure 70 has a sealing plug 74, and the sealing plug 74 is detachably mounted to the drain pipe 73 so as to adopt different drainage manners for different installation environments.

For example, in some embodiments, the drain structure 70 includes both a drain channel 71, a drain pump 72, a drain pipe 73, and a sealing plug 74. In an installation environment where the drain head is sufficient, the sealing plug 74 is opened, and the drain pipe 73 discharges the condensed water in the second drain pan 40 and the drain groove 71 to the outside, and at this time, the drain pump 72 does not operate, and the water is drained by the drain head. In an installation environment where the drain head is insufficient, drainage cannot be performed depending on the drain head, and at this time, it is necessary to install the seal plug 74 to the drain pipe 73 and drain the condensed water in the drain tank 71 to the outside by the drain pump 72. In addition, the sealing plug 74 has a sealing function for sealing the drain pipe 73 to prevent the drain pipe 73 from leaking water.

Here, the "drain head" refers to a height difference between an outlet end of the drain pipe body directly leading to the outside and the lowest point of the second drain pan 40 or the drain groove 71.
