Because the temperature required for defrosting is high, a temperature sensor is required to sense the temperature near the evaporator. The temperature sensor is very important in this case, since it is ensured that the frost layer is clean and that the temperature in the vicinity of the evaporator is not too high. However, the current temperature sensor on the evaporator pipeline is not firmly fixed, and can deviate in the transportation and production processes, so that the temperature sensing of the sensor is inaccurate, the defrosting is abnormal, and the defrosting effect is further affected.

In this embodiment, the accommodating cavity 320 is disposed in the first sleeve 311 as an example.

In one embodiment, the first sleeve 311 of the present application is a straight tube, the first sleeve 311 being disposed in a straight section of the evaporator tube 2; the second sleeve 312 is an arc-shaped tube, the second sleeve 312 is arranged on an arc section of the evaporator tube 2, and the accommodating cavity 320 is arranged on the first sleeve 311. In other embodiments, the first sleeve 311 and the second sleeve 312 are straight pipes, but an included angle different from zero exists between the length direction of the first sleeve 311 and the length direction of the second sleeve 312, and in this embodiment, the installation position of the first sleeve 311 and the second sleeve 312 is that one straight pipe of the evaporator pipeline 2 is bent.

In this application, first sleeve 311 and second sleeve 312 set up simultaneously on evaporator pipeline 2, because second sleeve 312 and first sleeve 311 are the kink structure, namely, second sleeve 312 in this embodiment is the arced tube, second sleeve 312 can restrict first sleeve 311 along the length direction skew of evaporator pipeline 2, still restrict first sleeve 311 and rotate on evaporator pipeline 2, thereby the position of sleeve 310 that first sleeve 311 and second sleeve 312 formed is fixed unchangeable for evaporator pipeline 2, and then the position of holding cavity 320 that is connected with sleeve 310 can not change, thereby the position of temperature sensor 1 also can not change, during the equipment, install temperature sensor 1 in ideal position, it can be in this position all the time in the production, transportation, guarantee temperature sensor 1 and detect the temperature of evaporator pipeline 2 in ideal position, guarantee good defrosting effect.
