Embodiment Construction

[0011] The refrigerator temperature control method includes the following steps

[0012] 1. The working states of the refrigerating chamber 1 and the freezing chamber 9 are divided into several control ranges (starting and stopping ranges), and the corresponding starting and stopping temperature points are selected according to the actual set gear.

[0013] 2. The refrigerator is equipped with temperature detection devices (temperature sensors) 2, 3, 4, 8, and the temperature signal obtained by the detection devices is transmitted to the main control chip 5 of the refrigerator;

[0014] 3. The ambient temperature is read by the ambient temperature sensor 2 and divided into several segments, and the current refrigerator start-stop control parameters are determined according to the current ambient temperature and the set temperature range.

[0015] 4. The main control chip 5 of the refrigerator performs on-off control on the current compressor 7 and the electric heater 6 by read...

Abstract

An intelligent temp control method for the refrigerator with a single refrigerating circulation features that the temp control parameters can be automatically determined according to the variations of ambient temp, cold storage temp and refrigerating temp to control compressor and electric heater, resulting in optimal temp.

Description

technical field [0001] The invention belongs to the technical field of household appliances, and in particular relates to a method for controlling the temperature of a refrigerator. Background technique [0002] In order to achieve more accurate temperature control, existing refrigerators often use multiple refrigeration cycles. However, for fixed-frequency compressors, it is difficult to optimize the matching of each refrigeration cycle with the compressor, resulting in low refrigeration efficiency of the refrigerator. , the energy saving effect is not good. The single refrigeration cycle refrigerator has a better energy saving effect due to the optimized matching of the refrigeration system. In the prior art, a mechanical thermostat is often used to roughly control the temperature. This method has the problem that the temperature of the compartment is greatly affected by the ambient temperature and the temperature of the compartment fluctuates greatly. Contents of the i...
