Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Figure 1 shows the structure of the electric control box of the existing air conditioner. Due to the different lengths and dimensions of the outdoor unit of the air conditioner, the linear distance between the middle partition and the right side panel is different, and the electric control box is installed on the middle partition and the right side panel. In the space between them, one side of it is lapped on the middle partition, and the other side is lapped on the right side panel of the outdoor unit of the air conditioner. Therefore, for different air conditioners, it is necessary to use outdoor electric control boxes of different lengths. To adapt to the size change of its outer chassis.

Fig. 2 is the electric control box structure of the air conditioner of the present utility model, in conjunction with Fig. 4, Fig. 7 and Fig. 8, it comprises electric control box body 20 and the support frame 30 that small sheet metal makes, one end at the bottom of electric control box also A finned radiator is provided, and the electric control box structure of the air conditioner is fixedly installed in the outdoor unit 10 of the air conditioner. Two self-tapping screws pass through the internal through hole 26 of the electric control box body 20 to connect one end of the telescopic electric control box structure Tightly fixed on the middle partition 11, the other end of the telescopic electric control box structure is fixed on the side plate 12 on the right side of the air conditioner through the through hole 38 by means of self-tapping screws. In order to build a firm and stable outdoor electric control box placement platform with a large box.

Referring to Fig. 3-4, a pair of installation holes 22 are provided at the bottom end of the electric control box body 20, and a plastic boss 21 is provided on one side of the installation holes. The installation holes 22 are used to fix the electric control box body and the support frame The two screw fixing bits of the connection. Three groups of buckles (the buckle group 23, the buckle group 24, and the buckle group 25) are punched in one piece at the bottom of the electric control box body 20. Figures 5-7 show the structure of the support frame. When the electric control box body 20 is connected to the support frame 30, the plate portion of the support frame 30 is inserted into the gap defined by the buckle group along the bottom of the electric control box body, and the support frame 30 The plate part first enters the buckle group 23 and is clamped by the two buckles split apart. When the support frame 30 continues to push forward, its board part will enter the buckle group 24 or even the buckle group 25 and be buckled. Limited displacement. Three pairs of through holes are arranged at different radial positions on the plate portion of the support frame 30, which are respectively through hole pairs (31, 32, 33). When the outdoor unit of the air conditioner is a large box, the plate portion of the support frame 30 The upper through hole pair 31 corresponds to the plastic boss 21 and the mounting hole 22 of the electric control box body, and the two are fastened by screws.
