Temperature sensor fixing structure for outdoor set of air-conditioner

Abstract

The invention belongs to the air conditioner technical field, in particular a temperature sensor fixing structure of an air conditioner outdoor unit which keeps constant distance with a condenser, is difficult to drop off and displace in production and transportation and is not influenced by operation of defrosting and heating, solving the problems of easy displacement and dropping-off, and abnormal operation of the air conditioner of the prior temperature sensor fixing structure due to incorrect and unstable temperature sensing in the process of defrosting and heating. The invention adopts the technical proposal that the inside of a shell is provided with an air conditioner outdoor unit, a temperature sensor support and a sensor, wherein the air conditioner outdoor unit consists of a compressor, an outdoor heat exchanger, an outdoor fan, a reversing valve, an expansion valve and a control box; and the temperature sensor support is fixed at a suction inlet of a rear panel of the air conditioner outdoor unit; the sensor support is formed by a support body which comprises a U-shaped temperature sensor bayonet and a screw hole right angle fixing part, the U-shaped temperature sensor bayonet is formed by means of injection moulding on one side and the screw hole right angle fixing part is formed on the other side, the temperature sensor is clamped in the U-shaped temperature sensor bayonet, and the fixing part is fixed on the edge of an inner wall of a right ribbed plate of a rectangle suction grill hole of the rear panel by screw holes and screws.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a temperature sensor fixing structure for an outdoor unit of an air conditioner that can maintain a constant distance from a condenser, is not easy to fall off or shift, and is less affected by defrosting and heating operations. Background technique [0002] Generally speaking, the air conditioner uses its refrigerant circulation system and air circulation system to exchange heat between the refrigerant and the air flowing in the room to achieve indoor cooling, heating or air purification, and provide people with a fresh and comfortable air environment. The refrigerant circulation system of an air conditioner is mainly composed of a compressor, a reversing valve, a condenser, an expansion valve, an evaporator, and other components. [0003] Air conditioners can be roughly classified into a split type air conditioner in which an outdoor unit and an indoor unit...

AI Technical Summary

Problems solved by technology

The circuit wires in the control box are connected to the executive components such as the compressor, the fan motor, and the temperature sensor to set and control the operation of the air conditioner. The temperature sensor of the existing air conditioner outdoor unit is as follows: figure 2 As shown, it is clamped in the U-shaped card slot of the sensor bracket. One side of the sensor bracket body is injected with a U-shaped card slot for the temperature sensor, and the other side is injected with three fixed inserts. The sensor bracket can be inserted and clamped on the outdoor heat exchanger with its inserts. On the refrigerant tube in the fin gap, this fixing method cannot fully guarantee the distance between the bracket and the heat exchanger during production, transportation, and use, and once the air conditioner is in defrosting or heating operation, its temperature sensor is blocked. Surrounded by frost, the temperature sensing is inaccurate or very unstable. As a result, the air conditioner often turns on and off abnormally, so customers complain a lot
