Problems solved by technology

[0002] In order to better maintain the nutrition of frozen food, ordinary freezing, rapid freezing and other freezing methods are usually used for food preservation. However, traditional ordinary freezing has disadvantages such as uneven temperature control in the freezing chamber and staying in the maximum ice crystal formation zone for a long time. For example, a kind of quick-freezing method is mentioned in a refrigerator with quick-freezing function in CN106123441A, but the energy consumption will increase due to the inability to intelligently identify the temperature at which the food reaches the ice crystal formation zone
In CN2527938Y, the thawing plate with quick-freezing function is placed in the refrigerator, which increases the cost and is not economical and practical
[0005] (2) Unable to intelligently identify the temperature range of the largest ice crystal zone
[0006] (3) Large energy consumption, and cause the temperature of other rooms to drop synchronously

Embodiment 1

[0050] Such as figure 1As shown, a quick-freezing control method for reducing food freezing damage is disclosed in this embodiment. The method uses the refrigeration system to generate cold air to cool the stored objects. During the quick-freezing process, in order to increase the supply to the quick-freezing area Cold, first reduce or stop the cooling of the non-quick-freezing area; monitor the temperature of the stored object in real time, when the temperature of the stored object reaches the first preset temperature, increase the speed of the condenser fan in the refrigeration system to reduce the temperature of the stored object The temperature drops to the second preset temperature. In this process, the set first preset temperature is higher than the maximum value of the temperature interval of the maximum ice crystal formation zone, and the second preset temperature is lower than the minimum value of the temperature interval of the maximum ice crystal formation zone. By...

Embodiment 2

[0059] The invention also discloses a quick-freezing refrigerator, which includes a control unit. The control unit adopts any one of the above-mentioned quick-freezing control methods.

Embodiment 3

[0061] Such as Figure 2-4 As shown, in this embodiment, the present invention discloses a quick-freezing refrigerator that reduces food freezing damage, and the refrigerator includes a refrigeration system, a temperature measurement unit and a control unit. In response to the control of the control unit, the refrigeration system provides cooling for the quick-freezing compartment and the non-quick-freezing compartment of the refrigerator; the temperature monitoring unit monitors the temperature of the stored objects in real time and sends the monitoring data to the control unit; the control unit controls the refrigeration system to control the temperature of the refrigerator. The stored objects in the freezing area are quickly frozen.

[0062] Before receiving the instruction of quick-freezing mode storage until the temperature of the stored object reaches the temperature range of the maximum ice crystal formation zone, control the damper of the compartment of the refrigerato...

Abstract

The invention provides a quick-freezing control method for reducing freezing damage of food, which adopts a refrigerating system to generate cold air to cool stored objects. In the quick-freezing process, the cooling to a non-quick-freezing area is reduced or stopped so as to increase the cooling to a quick-freezing area; the temperature of the stored object is monitored in real time; and when thetemperature of the stored object reaches a first preset temperature, the rotating speed of a condenser fan in the refrigerating system is increased, and the temperature of the stored object is reduced to a second preset temperature, wherein the first preset temperature is higher than the maximum value of the maximum ice crystal generation zone temperature interval, and the second preset temperature is lower than the minimum value of the maximum ice crystal generation zone temperature interval. The invention further provides a quick-freezing refrigerator which is more energy-saving while beingused for reducing the freezing damage of food and achieving quick-freezing.
