Problems solved by technology

[0008] However, when using a domestic refrigerator to supercool drinking water, it is not enough to make the cold air atmosphere in the box uniform. Sometimes the temperature distribution inside the drinking water causes the supercooling to be released, or makes the supercooling easy to be released.

Embodiment Construction

[0044] As explained in this section, in order to make supercooled drinking water in a household refrigerator, it is necessary to indirectly cool the drinking water, and it is very important to suppress the temperature distribution in the vertical direction generated inside the drinking water. Therefore, the supercooled container adopts an indirect cooling method that does not directly flow into the cold air to reduce the temperature distribution in the vertical direction in the drinking water to maintain the supercooled state.

[0045] In this embodiment, the following method is adopted: the outer peripheral portion of the container placed in the storage room of the household refrigerator, that is, the storage container is provided with an insulating layer, and the cold air flowing around the storage container is used to indirectly cool the beverage placed inside the storage container. water and fresh food. The temperature inside the storage container is detected by a temperat...

Abstract

When cooling drink water by using household refrigerator, it is insufficient to average cool gas in the refrigerator, internal temperature distribution of the drink water causes over cool release or the over cool is tend to be released. The invention provides a refrigerator having a storing chamber 10 cooling food stored in the space 65, which comprises a cool gas flow space 66 arranged around the space 65; a heat insulation layer 70 arranged between the space 65 and the cool gas flow space 66; a cool gas output port 57 outputting cool gas cooling temperature to the cool gas flow space 66 such that inside of the space 65 is cooled to cool temperature range lower than 0 DEG C to indirectly cool the food. The refrigerator, by the cooling mode, can restrain the generation of internal temperature distribution of the drink water such that drink water in over cool does not release over cool by chance.

Description

technical field [0001] The invention relates to a refrigerator. Background technique [0002] It has been known for a long time that water exists in a liquid state even below the freezing temperature, that is, the phenomenon of supercooling. For example, when drinking water in a container that has become supercooled is poured into a glass, the supercooling is instantly released due to the impact generated at this time, and sherbet-like ice is formed on the glass. Mixing smoothie-like ice with unfrozen drinking water is not only attractive, but also attracts attention as a new-taste drinking water. This product is actually supplied to customers in health clubs, pubs, bars, etc. However, since the supercooled state of drinking water is a physically very unstable state, it is difficult to maintain it. For example, the vibration transmitted to the drinking water, the cooling rate, the temperature distribution in the refrigerator, and the temperature distribution in the drinkin...
