[0041] At present, the outdoor heat exchanger of a mobile air conditioner is usually equipped with specially designed side plates at both ends. These side plates play an important role in structure, not only providing necessary mechanical support for the outdoor heat exchanger, but also effectively connecting with the middle partition plate and the bottom plate. In the design of the side plate, manufacturers usually reserve multiple screw holes on the surface thereof to facilitate the firm fixation of the outdoor heat exchanger on other components, however, in the actual assembly process, it is sometimes difficult to align the screw holes, resulting in low assembly efficiency.

[0042] The present utility model provides an air conditioner, which realizes the quick connection of the outdoor heat exchanger with the middle partition plate and the bottom plate through the buckle connection mode, so as to improve the assembly efficiency of the outdoor heat exchanger.

[0043] Please refer to Figures 1 to 11In an embodiment of the present application, the air conditioner 100 comprises a base plate 10, an air duct shell assembly 20, an outdoor side heat exchanger 30 and a buckle structure 40; the air duct shell assembly 20 is connected to the base plate 10; the outdoor side heat exchanger 30 is arranged between the base plate 10 and the air duct shell assembly 20; the buckle structure 40 comprises a first buckle assembly 42 and a second buckle assembly 41, the first buckle assembly 42 is arranged between the outdoor side heat exchanger 30 and the base plate 10, and the second buckle assembly 41 is arranged between the outdoor side heat exchanger 30 and the air duct shell assembly 20.

[0044] In the present application, the air conditioner 100 can be configured as a mobile air conditioner 100, and the air duct shell assembly 20 serves as the air duct structure of the air conditioner 100 and is not used for bearing weight, so that the air duct shell assembly 20 can comprise an air duct shell 22 and an additional support structure for mounting and fixing the outdoor side heat exchanger 30, so that at least two ends of the outdoor side heat exchanger 30 can be fixed. In the air conditioner 100 of the present application, the base plate 10 bears the weight of the entire air conditioner 100, including the compressor, the outdoor side heat exchanger 30, the evaporator, the fan and other electronic elements, so that the air duct shell assembly 20 can be directly connected and fixed to the base plate 10. After the air duct shell assembly 20 is connected and fixed to the base plate 10, the support structure on the air duct shell assembly 20 and the base plate 10 can serve as two relatively stable parts, and the two parts can connect and fix two parts of the outdoor side heat exchanger 30 through the second buckle assembly 41 and the first buckle assembly 42 respectively, so that the outdoor side heat exchanger 30 is clamped and fixed inside the entire air conditioner 100.

[0045] Among them, one of the first buckle assembly 42 and the second buckle assembly 41 can comprise two buckle conditions arranged along the front and back directions of the outdoor side heat exchanger 30, and the two buckle conditions are respectively clamped with two side plates 32 arranged along the front and back directions of the outdoor side heat exchanger 30, so as to limit the movement of the outdoor side heat exchanger 30 along the front and back directions. After the outdoor side heat exchanger 30 is assembled, the support structure and the base plate 10 can respectively limit the movement of the outdoor side heat exchanger 30 along the up and down directions, and one of the second buckle assembly 41 and the first buckle assembly 42 can further comprise a clamping protruding piece, which can be arranged on the side of the outdoor side heat exchanger 30 away from the air duct shell 22. The clamping protruding piece cooperates with the air duct shell 22 to limit the outdoor side heat exchanger 30 between the clamping protruding piece and the air duct shell 22, so as to limit the movement of the outdoor side heat exchanger 30 along the left and right directions. In this way, when the outdoor side heat exchanger 30 is limited in three directions, the clamping and fixing of the outdoor side heat exchanger 30 to the base plate 10 and the air duct shell assembly 20 can be achieved.

[0046] The technical solution of this utility model involves setting a second snap-fit ​​component 41 between the outdoor heat exchanger 30 and the air duct shell assembly 20, and setting a first snap-fit ​​component 42 between the outdoor heat exchanger 30 and the chassis 10. The outdoor heat exchanger 30 and the chassis 10 are snapped together by the first snap-fit ​​component 42, so that the outdoor heat exchanger 30 is pre-positioned on the chassis 10. When the air duct shell assembly 20 is subsequently installed on the chassis 10, the second snap-fit ​​component 41 set between the air duct shell assembly 20 and the outdoor heat exchanger 30 can be easily snapped and fixed to the outdoor heat exchanger 30, so that the outdoor heat exchanger 30 is installed and fixed between the air duct shell assembly 20 and the chassis 10. This enables the rapid assembly of the outdoor heat exchanger 30 on the air conditioner 100 without using the screw holes on the outdoor heat exchanger 30 to install and connect the chassis 10 and the air duct shell assembly 20, thereby improving the assembly efficiency of the outdoor heat exchanger 30.

[0047] The following section provides further details on how the outdoor heat exchanger 30 is pre-positioned onto the chassis 10 via the first snap-fit ​​assembly 42. (See attached document.)

The first latching member 421 and the second latching member 422 are spaced apart along a first direction. One end of the outdoor heat exchanger 30 along the first direction is limited and engaged with the first latching member 421, and the other end of the outdoor heat exchanger 30 along the first direction is limited and engaged with the second latching member 422.

[0048] In this invention, the first direction can be the front-to-back direction. The first fastener 421 and the second fastener 422 can be configured as clips protruding from the chassis 10. When the outdoor heat exchanger 30 is assembled onto the chassis 10, the two clips engage with the side plate 32 of the outdoor heat exchanger 30, thus restricting the movement of the outdoor heat exchanger 30 in the front-to-back direction. Furthermore, since the outdoor heat exchanger body 31 of the outdoor heat exchanger 30 passes through the side plate 32, and the side plate 32 supports the outdoor heat exchanger body 31, there are few positions on the side plate 32 that can be engaged with the first fastener 421 and the second fastener 422. Therefore, a protruding portion can be reserved on each of the two side plates 32 of the outdoor heat exchanger 30 for engaging with the first fastener 421 and the second fastener 422, respectively. This ensures that the outdoor heat exchanger 30 can be accurately positioned between the first fastener 421 and the second fastener 422.

[0069] In the utility model, since the outdoor side heat exchanger 30 is located at one side of the air duct shell 22, auxiliary buckle members 414 can also be arranged between the air duct shell 22 and the outdoor side heat exchanger 30 to limit the outdoor side heat exchanger 30 in the up-down direction.

[0070] The auxiliary buckle member 414 can include a limiting surface on the air duct shell 22 and a tab on the side plate 32 of the outdoor side heat exchanger 30. When the air duct shell assembly 20 is installed to the base plate 10, the limiting surface on the air duct shell 22 can be connected with the tab on the side plate 32 from top to bottom. After the air duct shell assembly 20 is assembled, the connection between the limiting surface and the tab can limit the outdoor side heat exchanger 30 from moving away from the base plate 10, so that the outdoor side heat exchanger 30 can be limited and fixed at multiple positions in the up-down direction by multiple buckle members, thereby improving the stability of the installation of the outdoor side heat exchanger 30 by the connection mode, and avoiding the problem of local stress concentration at the connection and fixing position of the outdoor side heat exchanger 30 due to too few limiting areas.

[0071] In the utility model, the outdoor side heat exchanger 30 includes the outdoor side heat exchanger body 31 and the side plates 32 located on both sides of the outdoor side heat exchanger body 31 along the first direction. The fourth buckle member 411 and the first buckle member 421 are limited and matched with one of the side plates 32, and the fifth buckle member 412 and the second buckle member 422 are limited and matched with the other side plate 32. The two side plates 32 can be used to install and support the outdoor side heat exchanger body 31. The outdoor side heat exchanger body 31 can be provided with multiple layers of heat exchange coils and multiple heat exchange fins installed on the heat exchange coils. The side plates 32 are used to support and install the outdoor side heat exchanger body 31. Therefore, when the first buckle assembly 42 and the second buckle assembly 41 are arranged, the first buckle assembly 42 can be connected with the two side plates 32, and the second buckle assembly 41 can be connected with the two side plates 32. In this way, when the outdoor side heat exchanger 30 is installed, the outdoor side heat exchanger body 31 does not need to bear the load.

[0072] The above description is only an exemplary embodiment of the utility model, and does not limit the patent range of the utility model. Any equivalent structural transformation made by referring to the utility model specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection range of the utility model.
