Method for controlling storage temperature of food in refrigerator and refrigerator

Abstract

The invention discloses a method for controlling the storage temperature of food in a refrigerator. The method comprises the following steps: determining the food weight corresponding to the type information according to the mapping relation between the food volume and the food weight corresponding to the type information of the food determined by the spectrum information; calculating the freshness of the unfrozen food; judging whether the total change condition of the food in a refrigerating chamber of the refrigerator tends to be severe or not according to the quality variation rate of the food; determining a storage weight value of the food according to the type information of the food to be placed; correcting the storage weight value of the food to be put according to the freshness; judging whether the lower limit value is in the currently determined optimal temperature range or not; and checking the weight rank of the food to be placed in the refrigerating chamber according to thecorrected storage weight value, judging whether the weight rank of the food to be placed is within the preset percentage, if so, controlling the temperature of the refrigerator according to the lowerlimit value of the optimal storage temperature range of the food to be placed, and if not, keeping the temperature of the refrigerating chamber unchanged.

Description

technical field [0001] The invention relates to the field of refrigerators, in particular to a refrigerator food storage temperature control method and a refrigerator. Background technique [0002] Refrigerator is a kind of refrigeration equipment that maintains a constant low temperature. Because most of the food is not easy to perish at low temperature and has a long storage time, the refrigerator has become a household appliance used by most families to keep fresh food. Bring convenience. [0003] However, after the food in the freezer of the refrigerator is frozen, it generally needs to be thawed before making. At present, the commonly used thawing method is mainly to use water to thaw, and the food to be thawed is taken out of the refrigerator and directly put into cold water or normal temperature water to thaw. However, this thawing method takes a long time, and will damage the quality of food, and has low reliability in use. And, because during the thawing process, ...

[0003] However, after the food in the freezer of the refrigerator is frozen, it generally needs to be thawed before making. At present, the commonly used thawing method is mainly to use water to thaw, and the food to be thawed is taken out of the refrigerator and directly put into cold water or normal temperature water to thaw. However, this thawing method takes a long time, and will damage the quality of food, and the reliability of use is low.

Moreover, since the food is usually heated and thawed during the thawing process, heating the food itself, especially raw meat, will cause the food to further deteriorate

For the thawed food, due to the difference in its degree of deterioration, if it is put into the refrigerator without any treatment, it will have a deterioration effect on the food already stored in the refrigerator; at the same time, if the thawed food itself is relatively fresh, However, the food already stored in the refrigerator is rapidly deteriorating. If the thawed food is put into the refrigerator without any treatment, it will have a deteriorating effect on the thawed food in the refrigerator.
