Mounting structure for heat exchanger fixing rack of split wall hanging type air conditioner indoor set

Abstract

An installation structure of a heat exchanger fixed frame of an indoor unit of a split wall-hanging air conditioner comprises the fixed frame and a main machine frame, screw holes are formed on the fixed frame and the corresponding position of the left side of the main machine frame, the fixed frame is arranged on the main machine frame by using screws to pass through the screw holes, a positioning hole is formed on the fixed frame, and a positioning pin which corresponds to the positioning hole is simultaneously arranged on the main machine frame; when the positioning hole is matched with the positioning pin, the screw holes on the fixed frame and the corresponding position of the main machine frame are maintained consistent. When in assembly process, the screw holes can be conveniently aligned only by inserting the positioning pin into the positioning hole, thereby reducing the time needed by the assembly and improving the production efficiency. In addition, the matching between the positioning hole and the positioning pin simultaneously plays the position limiting role, when the screws are screwed, distortion and dislocation cannot occur to the fixed frame, thereby ensuring the qualified rate of products and reducing the production cost.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a heat exchanger for a split wall-mounted air conditioner indoor unit that improves production efficiency by changing the fixing method between the fixing frame and the main frame to avoid installation misalignment of the fixing frame The installation structure of the fixed frame. Background technique [0002] Generally speaking, an air conditioner is a device that maintains the indoor air in the desired optimal state. For example, when the indoor temperature is high in summer, it sends cool air with low temperature to lower the indoor temperature, and when the indoor temperature is low in winter, it sends warm air with high temperature to keep warm. [0003] In addition, other uses of air conditioners also include various functions such as adjusting indoor humidity and recently appearing air purification. [0004] Air conditioners are roughly divided into integrated t...

AI Technical Summary

Problems solved by technology

[0025] In the prior art, screw holes are set at the corresponding positions on the left side of the fixed frame and the main frame, and the fixed frame is installed on the main frame through the screw holes through the screw holes, and the fixed frame and the main frame are fixed by 3 screw holes and screws. During the production and assembly process of the air conditioner, three pairs of screw holes must be aligned at the same time. This correction step takes a lot of time. Moreover, if the force is not uniform when tightening the screws, the screw holes will be misaligned, which will lead to the installation of the fixing frame. Misalignment means that the product is unqualified
