[0014] The accompanying drawings illustrate the structure of this utility model, and further details will be described below with reference to the drawings. In this embodiment, see the attached drawings. Figures 1-4 The portable cabinet air conditioner includes a housing 1, a base 2 and a top cover 3. The lower end of the housing 1 is fixed to the base 2, and the top cover 3 is fixed to the upper end of the housing 1. The housing 1 has an air inlet 4 and an air outlet 5. The air inlet 4 is located on the rear side of the housing 1 and has a mesh structure. The air outlet 5 is located on the front side of the housing 1 and has louvers. The housing 1 contains a fan and an evaporator 6. One side of the evaporator 6 is connected to a copper pipe 7 for conducting refrigerant. The rear side of the base 2 has a first copper pipe external interface 9, and the rear side of the top cover 3 has a second copper pipe external interface 10. Both the first copper pipe external interface 9 and the second copper pipe external interface 10 are equipped with detachable cover plates 8. The external end of the copper pipe 7 can be selectively arranged at the first copper pipe external interface 9 or the second copper pipe external interface 10. The upper and lower ends of the housing 1 are equipped with copper pipe outlets 13 to realize the forward or reverse installation of the evaporator.

[0015] The working principle of this utility model is as follows: a first copper pipe external interface 9 is pre-set on the base 2, and a second copper pipe external interface 10 is pre-set on the top cover 3. According to the user's installation environment requirements, before leaving the factory, the external end of the copper pipe 7 can be selectively arranged at the first copper pipe external interface 9 or the second copper pipe external interface 10. The cover plate 8 at the corresponding copper pipe 7 external interface is removed, and it can be connected to the external copper pipe. This reduces the material used for the upward wiring of the external copper pipe, reduces installation costs and improves installation efficiency. At the same time, the structure of the indoor unit has the versatility of evaporator 6 for both forward and reverse installation, reducing the use of molds and reducing production costs.

[0016] As a further improved specific implementation, the cover plate 8 is connected to the first copper pipe external interface 9 and the second copper pipe external interface 10 by a point-break type, which can be broken off and removed during use so that the copper pipe 7 can be connected to the external copper pipe.

[0017] As a further improved embodiment, the rear side of the evaporator 6 is provided with a fixed frame 11, and the two sides of the evaporator 6 are connected with the fixed frame 11 through fasteners, and the upper and lower ends of the fixed frame 11 are supported and fixed in the cabinet 1.

[0018] As a further improved embodiment, the copper pipe outlet 13 is provided with a positioning clamp block 12 between the copper pipe outlet 13 and the copper pipe 7, the positioning clamp block 12 is clamped on the copper pipe 7, and the positioning clamp block 12 is limitedly matched with the copper pipe outlet 13, and the corresponding positioning clamp block 12 is matched in the copper pipe outlet 13, and the outer end of the copper pipe outlet 13 is provided with a limiting step.

[0019] To sum up, the above is only a preferred embodiment of the present application, and is not used to limit the protection scope of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
