Terminal cover, compressor and air conditioner

Abstract

The invention discloses a terminal cover, a compressor and an air conditioner. The terminal cover disclosed by the invention comprises a main body and a fixing part, and the main body is provided with an assembling surface which abuts against a compressor shell; the fixing part is arranged at the side edge of the main body and extends in the direction far away from the main body, the fixing part is provided with a mounting surface, the mounting surface is provided with a containing groove and a wire outlet groove, the containing groove is used for containing a temperature sensing component, one end of the containing groove is closed, the wire outlet groove is far away from the closed end of the containing groove, one end of the wire outlet groove is communicated with the containing groove, and the other end of the wire outlet groove penetrates through the side edge of the fixing part; and when the terminal cover is assembled on the compressor shell, the mounting surface is arranged towards the compressor shell, so that the temperature sensing component can be in contact with the compressor shell. By adopting the terminal cover, the temperature of the compressor can be accurately detected, and the terminal cover is more sensitive to the temperature change of the compressor, so that a control system performs protection action in time, the compressor is more effectively protected, and the conditions of cavity abrasion, motor demagnetization and the like of the compressor are avoided.

Description

technical field [0001] The invention relates to the technical field of compression equipment and refrigeration, in particular to a terminal cover, a compressor and an air conditioner using the compressor. Background technique [0002] In the prior art, the air-conditioning external unit is equipped with a temperature-sensing component at the upper end of the exhaust pipe of the compressor, and the temperature detected at this position is used as the reference data for air-conditioning function control and reliability protection. When the air-conditioning system refrigerant leaks or the valve is closed , the temperature sensed by the temperature-sensing components at the upper end of the exhaust pipe is quite different from the temperature of the compressor shell. Body wear, motor demagnetization and other conditions. Although in the prior art, a shell temperature sensor is added to the compressor to detect the temperature change of the compressor, this will increase the cos...

[0002] In the prior art, the air-conditioning external unit is equipped with a temperature-sensing component at the upper end of the exhaust pipe of the compressor, and the temperature detected at this position is used as the reference data for air-conditioning function control and reliability protection. When the air-conditioning system refrigerant leaks or the valve is closed , the temperature sensed by the temperature-sensing components at the upper end of the exhaust pipe is quite different from the temperature of the compressor shell. Body wear, motor demagnetization, etc.

Although in the prior art, a shell temperature sensor is added to the compressor to detect the temperature change of the compressor, it will increase the cost of the compressor
