Fig. 1 is the flow chart of the defrosting control method of refrigerator according to an embodiment of the invention.As shown in Figure 1, the defrosting control method of refrigerator, comprises the steps: according to an embodiment of the invention
Step S101: the available machine time of testing environment temperature, compartment temperature and refrigeration.
Environment temperature and compartment temperature can be collected by corresponding temperature sensor, and a room includes but not limited to refrigerating chamber and refrigerating chamber.The available machine time of refrigeration refers to: the running time that the compressor of refrigeration system freezes each time.Can when compressor each run start, the opening time of recording compressed machine, and the available machine time obtaining refrigeration according to the shut-in time of compressor, or timing from the moment that compressor is opened, thus compressor continuous operating time can be obtained.
Step S102: environmentally the available machine time of temperature, compartment temperature and refrigeration obtains defrost periods and temperature is exited in defrost.
Particularly, comprising:
1, the mean value of available machine time and front N available machine time is compared.Wherein, shown in composition graphs 2, available machine time and front N available machine time all do not comprise refrigerator doors open time place available machine time, first available machine time after certainly also not comprising defrost and the pre-coo time before defrost.In one embodiment of the invention, N is such as 4, the mean value of more current available machine time and front 4 available machine times.
2, the continuous operating time of compressor is obtained according to the available machine time.Such as timing from the moment that compressor is opened, thus compressor continuous operating time can be obtained.
3, obtain compartment temperature according to compartment temperature and be greater than a duration for room shutdown temperature.Shutdown temperature refers to the temperature of the target temperature certain value being less than user's setting, and such as the usual target temperature by refrigerating chamber is set as about 5 DEG C, then shutdown temperature is usually less than about target temperature 2-3 DEG C.
4, environmentally temperature judges the variable quantity of environment temperature.The fluctuation of such as, environment temperature in certain hour.Certain hour can be the continuous operating time of above-mentioned compressor, available machine time or compartment temperature are greater than a duration for room design temperature.
