Problems solved by technology

[0004] The present invention implements periodical cooling and heating control on the temperature of the storage environment of the cooling object. In the cooling stage, multiple cooling targets are preset for cooling in stages. In the heating stage, a single heating target is preset for continuous heating. The invention can effectively solve the problem that after the cooling object is frozen, it takes a long time to unfreeze and the quality of the cooling object decreases

Embodiment 1

[0055] like Figure 5 As shown, the present embodiment provides a supercooled non-freezing storage refrigerator, including:

[0056] Cooling chamber 2 is used to implement overcooling and non-freezing preservation of the cooling objects placed therein.

[0057] The refrigerating system 5 is used to produce cold air to refrigerate the cooling objects in the refrigerator, and specifically includes: a compressor 51, a condenser 52, an anti-condensation pipe 53, a drying filter 54, a freezing evaporator 55, and an air return pipe assembly 56. Example of a refrigeration system 5 such as Figure 4 shown.

[0058] The control unit includes: it includes: a controller, a temperature regulating device, a temperature sensor 4, a timer, and an electric field generating device 6, and is characterized in that: a controller is used to control other components of the control unit and the refrigeration system 5; the temperature regulating device , used to adjust the temperature of the cooli...

Embodiment 2

[0068] Attached below figure 1 The content of the specific embodiment of the present invention is described in detail: the electric field generating device 6 is turned on, and the cooling object under the action of the electric field is controlled for cooling and heating, and the cooling and heating control includes the following steps:

[0069] S1: a staged cooling process, so that the cooling chamber 2 is cooled step by step to a second temperature T2 lower than the freezing point T0 of the object to be cooled according to the preset cooling target and preset cooling time;

[0070] S2: Continuous heating process, the temperature of the cooling chamber 2 is continuously raised to the first temperature T1 which is equal to or higher than the freezing point T0 of the object to be cooled.

[0071] Among them, T1>T2, the temperature range of T1 is 0℃~10℃, and the temperature range of T2 is -10℃~0℃;

[0072] The temperature difference between T1 and T2 ranges from 0°C to 20°C.

Embodiment 3

[0098] Such as figure 2 As shown, this embodiment provides another control method for supercooling without freezing storage. After the user puts the cooling object into the refrigerator cooling chamber 2, he turns on the electric field generator 6, so that the cooling object is under the action of the electric field, and the cooling chamber 2 The infrared temperature sensor detects the surface temperature Ts of the cooling object. If it detects that the surface temperature Ts of the cooling object is equal to or lower than the second temperature T2, the refrigerator control unit controls the cooling chamber 2 to heat up first. Compared with embodiment 2, in this embodiment First execute the heating program and then the cooling program, and then enter the control cycle of heating and cooling, and the rest are the same as in Embodiment 2, and will not be repeated here. The temperature variation of present embodiment cooling chamber is as follows Figure 8 As shown, the tempera...

Abstract

The invention relates to a supercooling non-freezing storage control method and a refrigerator. The method comprises the steps of turning on an electric field generating device to enable a cooled object to be in the electric field, and carrying out periodic heating and cooling control on the temperature of a cooling chamber, wherein staged step-by-step cooling is adopted in the cooling stage to reduce the temperature below a freezing point, the cooled object is enabled to stably enter a supercooling state, the cooled object is prevented from generating needle-like ice crystals due to freezingto damage the cell structure, and the flavor of the cooled object is further prevented from being damaged during thawing; and the storage environment temperature of the cooled object is continuously increased to be equal to or higher than the freezing point temperature by adopting a continuous heating mode in the heating stage. Through continuous circulation of heating and cooling, the cooled object is not frozen near the freezing point, and the fresh-keeping period of the cooled object is prolonged.

Description

technical field [0001] The invention relates to a refrigerator control method and a refrigerator, in particular to a control method for supercooling without freezing storage and a refrigerator. Background technique [0002] With the rapid development of air-cooled refrigerators and the improvement of consumers' requirements for the freshness of cooling objects, the multi-function of refrigerators has developed rapidly, and at the same time, the requirements for controlling the storage temperature of cooling objects in refrigerators have become more and more stringent.
