Embodiment Construction

[0025] The technical solutions of the present invention will be further described below through specific embodiments.

[0026] There is an imagination in nature that water does not freeze below 0 degrees, and this phenomenon is called a supercooled state. The so-called supercooling is the state where the food is below its freezing temperature without freezing. The water in the supercooled state can be frozen into ice through a certain way. This way is a certain stimulus from the outside. The general stimulus includes vibration and a large cold shock can release the supercooled state.

[0027] figure 1 The timing diagram of the control logic of the refrigerator provided by the present invention. like figure 1 As shown, the freezing temperature of food is divided into the following five states:

[0028] (1) Unfrozen state: the state in which the temperature of the food has dropped from the ambient temperature to above the freezing point.

[0029] (2) Supercooled state: The ...

Abstract

The invention discloses a refrigerating and freshness retaining storage method of a refrigerator. The refrigerating and freshness retaining storage method includes the following steps: first enabling food to enter a supercooling state; after the food enters the supercooling state, bringing outside stimulation to the food to enable the temperature of the food to reach the freezing temperature; and controlling frequency of a fan to enable the food to finish a freezing state quickly. A control device of the refrigerator comprises a detection unit, a control unit, and a judging unit. The detection unit, the control unit, and the judging unit cooperate together so as to enable the food in the refrigerator to slowly freeze before the freezing temperature, when the refrigerator conducts freezing, the food is quickly frozen so that the food is enabled to fall back to the freezing state from the supercooling state, and freezing time is shortened. The method can avoid cooling injury such as protein denaturation and cellular tissue injury caused by freezing, and prevents food quality from deteriorating due to the reasons such as oxidation and bacterial reproduction.

Description

technical field [0001] The present invention relates to the field of refrigerators, and more specifically, relates to a novel method for freezing and fresh-keeping storage of refrigerators. Background technique [0002] Existing freezing and fresh-keeping technology mainly comprises rapid freezing and fresh-keeping technology and the freezing and fresh-keeping technology of Mitsubishi Electric Corporation. [0003] Rapid freezing and fresh-keeping technology can quickly pass through the temperature zone of -1°C to -5°C in the maximum ice crystal formation zone, shorten the time of ice crystallization in this temperature zone as much as possible, and suppress the formation of larger ice crystals. But there are still some problems in the rapid freezing and fresh-keeping technology. For example, when the food object is large, the food starts to freeze from the surface. When the surface temperature has quickly passed through the maximum ice crystal formation temperature zone, t...
