Generally, in the working state of the air conditioner wall mounted indoor unit, the heat of each part of the evaporator 10 can be uniform, that is, the heat exchange uniformity on the evaporator 10 during the working process of the product can be achieved, thereby ensuring the energy efficiency of the product. In some embodiments, the housing 100 may also include a first mounting position 103 and a second mounting position 104 arranged opposite to the first mounting position 103. The first mounting position 103 and the second mounting position 104 are U-shaped, and the first mounting position 103 is also provided with a U-shaped groove 1031, and the second mounting position 104 is arc-shaped. In some embodiments, the indoor unit of the air conditioner wall mounted device further comprises a motor mounting structure 300, and the motor mounting structure 300 is also arc-shaped as a whole, and the motor mounting structure 300 is closely matched with the second mounting position 104 to form a circular end face.

[0026] Read also Figures 6 to 8The utility model provides an evaporator assembly, which includes an evaporator 10. The evaporator 10 is a multi-stage structure, including an upper evaporator 11, a middle evaporator 12 and a lower evaporator 13. A plurality of refrigerant U-shaped tubes 20 are arranged in the evaporator 10. The plurality of refrigerant U-shaped tubes 20 extend out of the first end of the evaporator 10, and at least one refrigerant U-shaped tube 20 is extracted from the end of the first end of the lower evaporator 13 to form an evaporator tube extraction hole 21. The evaporator assembly also includes an evaporator end plate 30 that is clamped with the evaporator 10. The evaporator end plate 30 is provided with a plurality of annular grooves 301 that are adapted to the refrigerant U-shaped tubes 20 and through holes 302 that correspond to the positions of the evaporator tube extraction holes 21. The number of through holes 302 can be set to two. It can be understood that in some other embodiments, the number of through holes 302 can also be one or more, which can be set according to needs. The evaporator end plate 30 is embedded in the end surface of the first end of the evaporator 10, and completely covers the end surface of the first end of the evaporator 10. The side wall of the evaporator end plate 30 is tightly matched with the first mounting position 103, and the clearance between the two is 1mm, which can fix the evaporator 10 to prevent the evaporator 10 from moving left and right.

The refrigerant U-shaped pipe 20 can be a copper pipe in some embodiments. It is understandable that in some other embodiments, at least one refrigerant U-row tube 20 can be removed from the end of the first end of the lower evaporator 13 and the end of the first end of the upper evaporator 11 to form an evaporator tube extraction process. By removing two refrigerant U-row tubes 20 from the ends of the first end of the upper evaporator 11 and the lower evaporator 13 where the air circulation of the evaporator 10 is the worst, a symmetrical tube extraction process design of the evaporator 10 is formed. This design can maximize the use of the air circulation of the air conditioner hanging unit, remove the two refrigerant U-row tubes 20 with the worst exchange, and can meet the air conditioning performance requirements and reduce costs by reducing the amount of copper tubes. It has very practical economic value without changing the mold of the evaporator 10. Two or more refrigerant U-row tubes 20 can also be removed from the end of the first end of the lower evaporator 13 and the end of the first end of the upper evaporator 11. The number and position of the removed refrigerant U-row tubes 20 are set differently according to needs.

The depth of the plurality of annular slots 301 is greater than the length of the plurality of refrigerant U-row tubes 20 extending therefrom, which can prevent the evaporator 10 from shifting toward the side of the heat exchange fan 200, and protect the plurality of refrigerant U-row tubes 20 extending therefrom from being flattened. A second slot 32 is formed on the evaporator end plate 30, and the second slot 32 is arc-shaped, and the second slot 32 is engaged with a portion of the heat exchange fan 200 arranged in the air conditioner hanging unit. An arc-shaped step 321 is formed on the inner side of the second slot 32, and the tail of the arc-shaped step 321 extends toward the air conditioner hanging unit to form an extension plate 322. By providing the arc-shaped step 321 , the evaporator end plate 30 can be better and tightly matched with the first installation position 103 , thereby fixing the evaporator 10 and preventing the evaporator 10 from moving left and right.

[0028] In some embodiments, a plurality of refrigerant U-shaped tubes 20 form a plurality of refrigerant tube loops, and at least one refrigerant tube loop is respectively provided in the upper evaporator 11, the middle evaporator 12, and the lower evaporator 13, and the multi-stage evaporator 10 is semi-enclosed and distributed outside the heat exchange fan 200 of the indoor unit of the air conditioner. It can be understood that in some other embodiments, the evaporator assembly further includes a front housing, which is covered on the outside of the front surface of the evaporator 10, and the portion of the evaporator end plate 30 extending toward the evaporator 10 is located on the inner side of the front housing, which will not conflict with the accurate installation of the front housing.
