The air conditioner 100 of the present invention further includes a drain device 50 for collecting and draining condensed water formed inside the air conditioner 100.
The drain 50 comprises a first drip tray 52 and a second drip tray 54, the second drip tray 54 being located below the first drip tray 52 in a first direction. Specifically, a first drip tray 52 is positioned between the evaporator 30 and the compressor 10, and a second drip tray 54 is positioned on a side of the compressor 10 facing away from the second drip tray 54. Thus, when the air conditioner 100 is operated, the condensed water formed on the outer surface of the evaporator 30 can enter the first water collecting tray 52 under the action of its own weight, and the condensed water formed on the outer surfaces of the devices such as the pipeline connecting the evaporator 30 and the compressor 10 in the air conditioner 100 can enter the second water collecting tray 54 under the action of its own weight, so that the condensed water formed inside the air conditioner 100 can be completely collected by the first water collecting tray 52 and the second water collecting tray 54.
Specifically, in the present embodiment, the first water collecting tray 52 has a first water collecting space 53, the second water collecting tray 54 has a second water collecting space 55, and the first water collecting space 53 and the second water collecting space 55 can respectively receive the condensed water dropping above the first water collecting tray and the second water collecting space 55. The drain 50 further comprises a connection mechanism 56, which connection mechanism 56 is connected between the first and second drip trays 54 and communicates the first and second drip spaces 53, 55. Wherein, the second water collecting tray 54 is provided with a water outlet 541 communicated with the second water collecting space 55. Thus, the condensed water collected in the first water collecting space 53 enters the second water collecting space 55 through the connection mechanism 56, the condensed water in the first water collecting space 53 is collected in the second water collecting space 55, and the finally collected condensed water is discharged from the water discharge opening 541 of the second water collecting tray 54.

During the swinging of the air conditioner 100, the condensed water in the first water collecting tray 52 can enter the second water collecting tray 54 through the relatively lower one of the first connecting assembly 561 and the second connecting assembly 563 and then be discharged through the relatively lower one of the first water discharge opening 543 and the second water discharge opening 545, so that the condensed water can be reliably discharged and can be used as the marine air conditioner 100.
In some embodiments, the top surface of the second drip tray 54 facing the first drip tray 52 is grooved to form a second drip space 55, such that the grooves are formed on the top surface of the second drip tray 54, and the condensate formed on the outer surface of the top device of the second drip tray 54 can drip down to the second drip tray 54 under its own weight and finally collect in the grooves. In addition, the ends of the first connecting assembly 561 and the second connecting assembly 563, which are opposite to the first water collecting tray 52, are communicated with the groove, so that the condensed water in the first water collecting tray 52 can be collected into the groove through any one of the first connecting assembly 561 and the second connecting assembly 563.
Furthermore, the groove extends in a direction parallel to the second direction, and the first water outlet 543 and the second water outlet 545 are respectively communicated with two opposite ends of the groove in the second direction, so that condensed water collected in the groove can freely flow in the second direction and can be discharged from any one of the first water outlet 543 and the second water outlet 545.
In some embodiments, the top surface of the second water collecting tray 54 includes a first guide surface 552 and a second guide surface 554, the first guide surface 552 and the second guide surface 554 are located on opposite sides of the recessed groove, respectively, in a third direction intersecting the second direction, and the first guide surface 552 and the second guide surface 554 are provided obliquely downward, respectively, in directions approaching each other.
