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

[0037] 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.

[0038] 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

A refrigerator is provided to improve maintenance of a supercooling state by indirect cooling which is operated at a temperature lower than 0 degree in the space. A refrigerator comprises: a storage room; a cool air circulating space(66); a heat insulating layer(70); an outlet(57); and a cooler. The storage room cools foods stored in space. The cool air circulating space is formed around the space. The heat insulating layer is formed between the space and the cooling air circulating space. The outlet emits the cool air of cooling temperature in a cool air circulating space for refrigerating the space to freezing temperature less than 0 degree. The cooler generates cool air emitted from the cool air outlet. The indirect cooling for food is operated at a temperature lower than 0 degree in the space.

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...
