Background technology
The low temperature auto-compensation be winter auxiliary compressor can automatically start the electric heater unit of work.Because when refrigerator uses in the winter time, the work of compressor is to control by the temperature controller in the refrigerating chamber, temperature controller is to realize just that by the temperature in the refrigerating chamber separation of contact is with closed, and winter temperature is very low, the indoor variations in temperature of refrigerator cold-storage is very slow, so will cause compressor can't start work, cause refrigerator not freeze.So the electric heater unit that will set up little function in refrigerating chamber uses in the winter time the time.The work of will switching on of this switch connection, electric heater, the temperature in the refrigerating chamber will be accelerated to raise, thereby make the temperature controller closing of contact, make compressor can start work, guarantee that refrigeration for refrigerator is good.
Along with the continuous expansion in refrigerator market, refrigerator product internationalization and regional disparity, vast territory and abundant resources in special China, and the North and South temperature difference is larger, needs wide climate zone refrigerator, in the low situation of environment temperature, use refrigerator, just temperature compensation function must be arranged.
At present, mostly be greatly direct cooling refrigerator with the low temperature auto-compensation.
Such as Fig. 1, for utilizing in early days interior light to add decompression capacitor, manual compensation switch composition, when refrigerator doors is closed, as long as manual compensation switch closure, illuminating lamp namely obtain part voltage by capacitance decompression, add thermal compensation, this circuit cost is low, but compensate the moving control of complete armrest, close the manual compensation switch when the user forgot in the season that does not need to compensate, can cause the dual waste of energy consumption.
Fig. 2 can well overcome the shortcoming that the first scheme exists for the circuit of self-induction auto-compensation after improving.
The utility model content
