[0035] Please refer to figure 1 , the embodiment of the present invention provides a protection device 1 for protecting the compressor 34 in the air conditioner. It can control the compressor 34 to cut off the power when the temperature of the compressor 34 is too high, prevent the temperature of the compressor 34 from continuing to rise, prolong the service life of the compressor 34, and is safe, reliable and practical. In this embodiment, the compressor 34 is provided with a motor 35. When the compressor 34 runs for a long time, lacks fluorine or breaks down, the temperature of the motor winding will rise and exceed the preset value, which will affect the service life of the motor winding, and even Burn motor 35, protection device 1 can control compressor 34 power-off when the temperature of motor winding exceeds preset value, so that motor 35 stops working, prevents that the temperature of motor winding continues to rise, and compressor 34 is protected.

[0054] Please refer to Figure 7 , the embodiment of the present invention provides an air conditioner 30 for regulating indoor air temperature. The air conditioner 30 includes an indoor unit 31 , an outdoor unit 32 and a protective device 1 . Wherein, the basic structure, principle and technical effect of the protection device 1 are the same as those of the first embodiment. For brief description, for the part not mentioned in this embodiment, reference may be made to the corresponding content in the first embodiment.

[0055] In this embodiment, the indoor unit 31 is installed indoors, and the outdoor unit 32 is installed outdoors. The indoor unit 31 and the outdoor unit 32 work together to regulate the indoor temperature. The outdoor unit 32 includes a power supply 33 and a compressor 34 with a motor 35. The alarm 24 is installed in the indoor unit 31, which is convenient to remind the user. When the preset value is exceeded, the power supply 33 and the compressor 34 are ...

Abstract

The invention provides a protection device and an air conditioner, and relates to the technical field of air conditioning. The protection device comprises a detecting box, a heat conducting part, an expanding medium, a floating part, an extending rod, a first conductive assembly and a second conductive assembly. The detecting box is filled with the expanding medium, one end of the heat conductingpart is used for being connected with a compressor, and the other end of the heat conducting part stretches into the detecting box. The floating part is slidingly arranged in the detecting box, and floats on the expanding medium. The floating part is fixedly connected with the extending rod, and the extending rod stretches out of the detecting box and is in sliding fit with the detecting box. Thefirst conductive assembly is connected with the second conductive assembly through the extending rod. Compared with the prior art, the protection device has the beneficial effects that due to the factthat the heat conducting part in contact with the expanding medium and the extending rod connected with the floating part are adopted, the first conductive assembly and the second conductive assemblyare disconnected when the temperature of the compressor is too high, the temperature of the compressor is prevented from continuing to rise, the service life of the compressor is prolonged, safety and reliability are achieved, and high practicality is achieved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a protection device and an air conditioner. Background technique [0002] With the progress of the times, air conditioners have entered thousands of households. How to prolong the service life of air conditioners and improve the safety of air conditioners has become an urgent problem to be solved. When the current air conditioner runs for a long time, lacks fluorine or breaks down, the temperature of the motor winding in the compressor will exceed its set temperature, resulting in a sharp decline in the service life of the motor winding, or even burning, which is highly dangerous. Contents of the invention [0003] In view of this, the present invention aims to propose a protective device, which can control the power-off of the compressor when the temperature of the compressor is too high, prevent the temperature of the compressor from continuing to rise, prolong the s...
