A kind of refrigerator method for heating and controllingTechnical field
The present invention relates to refrigeration equipment technical field of control method, and in particular to a kind of computer heating control of refrigerator high temperature compartmentMethod.
Background technique
Refrigerator is a kind of refrigeration equipment for keeping constant low temperature, be in life common one kind for low-temperature preservation food orThe electric appliance of other articles is widely used in life, industrial circle.With the development of science and technology and improvement of living standard, disappearMore stringent requirements are proposed for functionality of the person of expense to refrigerator, currently, existing refrigerator can only mostly realize freezing, refrigeration and low temperature storageThe alternating temperature of temperature range is deposited, such as -24 DEG C~8 DEG C of alternating temperature can not carry out the production of Yoghourt, pickles, it is even more impossible to realize meatIt thaws, it is difficult to adapt to the needs of consumer's increasingly diversification.
By patent retrieval, there are following known technical solutions:
Patent 1:
Application number: CN201611192191.1, the applying date: 2016.12.21, authorized announcement date: 2017.04.26, this hairIt is bright to be related to field of home appliance technology, a kind of refrigerator refrigeration system, refrigerator and defreezing method are provided.The refrigerator refrigeration system, packetInclude compressor, evaporator and the first condenser being formed into a loop by piping connection, wherein the evaporator and described first coldIt is connected with throttling set between condenser, further includes the second condenser for defrosting, second condenser and the first condenserParallel connection, and first condenser and second condenser select a connection.The refrigerator refrigeration system utilizes the second condenserCondensation heat thaws to frozen food, so that the second condenser takes into account the effect of condensation heat release and thawed foodstuff, to avoidInsulation, the requirement of fire prevention aspect of temperature-changing chamber caused by being thawed using electric heating wire are very high, and protection cost and hidden danger are veryHeight, and for defrosting electric heating wire power consumption the problem of.
The patent is increased solenoid valve in refrigeration systems and is thawed using the condensation heat of the second condenser to frozen food,But the patent needs in addition to increase in refrigeration systems condenser and valve, and components are more to be caused to heat reliability in actual useDifference, and the heat dissipation capacity of refrigeration system is limited, is unable to satisfy the high situation of heat demand.
Patent 2:
Application number: CN201310430932.5, the applying date: 2013.09.22, authorized announcement date: 2014.06.11, this hairIt is bright to be related to a kind of controlling method for refrigerator of the temperature-changing chamber with defrosting function, include the following steps: that fast-refrigerating reaches refrigeration settingTemperature；Close compressor and refrigeration air door, open refrigeration heater strip and refrigeration blower, are alternating temperature greenhouse heating, until setting temperature of thawingDegree, until the setting time thawed.The present invention makes temperature-changing chamber while being provided with defrosting function, user-friendly, and guaranteesFood defrosting speed is fast, and can avoid the food spoilages such as the meat for failing to take out in time.
The patent is thawed by opening refrigeration heater strip and refrigeration blower for alternating temperature greenhouse heating.Such structure leads to refrigeratorProduction cost it is excessively high, and then the competitiveness of product in market is caused to decline, it is difficult to universal to use.
Through the above search, it has been found that above technical scheme does not influence novelty of the invention；And the above patent textThe intercombination of part is without destroying creativeness of the invention.
Summary of the invention
