Problems solved by technology

[0004] (1) The uneven temperature drop in the supercooling process causes the supercooling to be released in advance
[0005] (2) The effect of supercooling relief is not good, by increasing the wind speed or air volume
[0006] (3) The depth of supercooling is shallow, and it cannot enter the supercooling state well

Embodiment 1

[0118] [Example 1: The overall composition of the refrigeration equipment and the specific embodiment of the corresponding instant freezing method]

Embodiment 1-1

[0119] [Example 1-1: Overall configuration of refrigeration equipment]

[0120] figure 2 It is a schematic diagram of a refrigerator with instant freezing function according to an embodiment of the present invention. The refrigeration device can be commonly known refrigerators, freezers, cold storage and other equipment with refrigeration functions. In this embodiment, a refrigerator example. Specifically, the refrigerator may include an outer shell, an inner container disposed in the outer shell, and an insulating material filled between the outer shell and the inner container. A cooling chamber for storing objects to be refrigerated is defined in the inner bag, and the cooling chamber includes a freezing chamber 12 that can be used to realize the instant freezing function. The instant freezing function can be a single instant freezing chamber, or can be An instant freezing chamber that can be converted from ordinary freezing or refrigerating. The refrigerator in this embo...

Abstract

The invention relates to an instant freezing control method for a refrigeration device and the refrigeration device. The instant freezing control method for the refrigeration device includes a stagedtemperature reduction supercooling process, a supercooling release process, and a conventional refrigeration preservation process. In the supercooling temperature reduction process, staged temperaturereduction is performed on a cooled item, and each stage of temperature reduction is realized by performing cooling control on an instant freezing chamber, and each temperature reduction stage of thestaged temperature reduction supercooling process is set with a compressor preset accumulative working duration corresponding to the stage; and a compressor is controlled to work periodically stage bystage according to the preset accumulative working duration. In the supercooling release process, the supercooling release operation is performed by increasing the compressor rotation speed and reducing the capillary group flow, so that the item stored in the instant freezing chamber is released from supercooling, then, the stored item is instantly frozen (called instant freezing for short), andthe frozen item is stored for a long time at a conventional refrigeration preservation temperature.

Description

technical field [0001] The invention relates to a control method for instant freezing of refrigeration equipment and refrigeration equipment, in particular to a control method capable of realizing instant freezing of food and a refrigerator. Background technique [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. ; And although rapid freezing can pass through the maximum ice crystal formation zone fast, the production cost is higher, which is unfavorable for popularization and application on the refrigerator. The supercooling freezing technology can make the fresh-keeping objects form uniform and fine ice crystals after the supercooling process, which can better maintain the fl...
