Controller of air conditioner

Abstract

A controller for an air conditioner includes a control plate, a control box and a control plate fixing card. The control plate fixing card includes a card end, a body, a restraining piece and a pin; wherein, the body is integratedly formed by a four-bladed vane arranged in the middle and two round end plates connected at the two ends of the four-bladed vane. The card end is connected at the external surface of the plate at end of the body and is in a gripping shape. The restraining piece is provided with an arc tabular structure and the central part of the external surface is fixed on the external surface on the plate at the other end of the body. The pin is provided with an arrow-shaped structure and the back end of the pin is connected on the central part of the internal surface of the restraining piece. The controller for an air conditioner of the invention can lead the arrangement of the control plate in the control box to be more stable; thereby the problem of damage on the control plate can not occur, thus improving the product quality. Besides, as the control plate fixing card can be designed with different lengths, the control plates with different dimensions can be arranged in the control box with a same dimension; thereby being able to reduce the quantity of dies in large scale, thus being able to reduce the manufacture cost.

Description

technical field [0001] The invention relates to an air conditioner, in particular to an air conditioner controller with a more stable structure, which can improve product quality and reduce production cost. Background technique [0002] An air conditioner is a device that makes its internal refrigerant undergo a refrigeration or heating cycle consisting of a compression process, condensation process, expansion process, and evaporation process. When the air conditioner is in the refrigeration cycle, the refrigerant compressed by the compressor and turned into a high-temperature and high-pressure state can flow to the condenser under the guidance of the four-way valve, and dissipate heat to the outside in the condenser, and then significantly reduce when flowing through the expansion valve. Its temperature and pressure, then the low-temperature, low-pressure refrigerant absorbs heat as it flows through the evaporator, and finally passes through the liquid storage tank and flow...

AI Technical Summary

Problems solved by technology

like Figure 1 ~ Figure 2 As shown, at present, the control board 2 is fixed in the chassis 1 of the control box using a three-point fixing method, that is, the control board 2 is fixed on the control box by using the fixing device to penetrate through the three fixing holes 3 on the three corners of the control board 2. On the chassis 1, due to the asymmetry of the three fixed points on the control board 2, the entire structure is not stable enough, so quality problems such as damage to the control board 2 are prone to occur during use, which will cause dissatisfaction among consumers

In addition, due to the wide variety of control boards 2 and different varieties, the size of the control box also needs to be changed accordingly. At this time, multiple sets of molds need to be prepared, because the production cost of the molds is relatively high, which will undoubtedly increase the production cost.
