Temperature control method and device of temperature changing subchamber and refrigerator with same

Abstract

The invention provides a temperature control method of a temperature changing subchamber, which comprises the following steps of: setting temperatures of a refrigerating chamber and a temperature changing subchamber; obtaining a refrigerating start temperature and a refrigerating suspension temperature of the temperature changing subchamber according to a temperature setting value of the refrigerating chamber, a temperature setting value of the temperature changing subchamber and a sectioning compensation temperature difference table; and detecting the current temperature of the temperature changing subchamber and controlling the refrigeration of the temperature changing subchamber according to the current temperature value, the refrigerating start temperature and the refrigerating suspension temperature. The invention carries out accurate control on the temperature of a temperature changing chamber by a principle of the temperature control sectioning compensation of the temperature changing chamber, thereby more favorably realizing all functions of freshness retaining, freezing point temperature and soft freezing of the temperature changing chamber.

Description

technical field [0001] The invention relates to the technical field of home appliance manufacturing, in particular to a temperature control method and device for variable temperature sub-compartments and a refrigerator with the same. Background technique [0002] With the continuous improvement of people's living standards, the quality requirements for household appliances are also getting higher and higher. In order to realize multiple functions spanning the refrigeration and freezing temperature zones, such as refrigeration, freshness preservation, ice temperature and freezing, an independent refrigerator is installed in the refrigerator. Variable temperature sub-compartments. However, although the current temperature-variable sub-compartment is provided with an independent temperature control function, the temperature control accuracy is very poor because the influence of the temperature fluctuation of the refrigerating room on the sub-compartment is not considered. In a...

Problems solved by technology

However, although the current variable temperature sub-compartment is equipped with an independent temperature control function, the accuracy of temperature control is very poor because the influence of the temperature fluctuation of the refrigerator room on the sub-compartment is not considered.

In addition, since the above-mentioned refrigerators do not have independent and accurate variable temperature sub-compartment temperature control, their variable temperature range is greatly limited. Generally, they can only be passively maintained between 0 and 5°C with changes in the temperature of the refrigerator compartment, and cannot be controlled. To straddle refrigerated and frozen temperature zones
