Preservation chamber and refrigerator with preservation chamber

Abstract

The invention provides a preservation chamber arranged in a compartment of a refrigerator and the refrigerator with the preservation chamber. The preservation chamber comprises a shell and an inner container, wherein the inner container is held in the shell; a supporting frame is arranged in the shell; the inner container is arranged on the supporting frame, so that an accommodating space is formed between the inner container and the shell; the shell is provided with a first air inlet; the inner container is provided with a second air inlet corresponding to the first air inlet; cold-blast aircan enter the inner container from the second air inlet to quickly cool food; the preservation chamber also comprises an air door used for opening or closing the second air inlet and an air guiding element arranged in the accommodating space; the air guiding element is arranged along the peripheral side of the second air inlet, so that at least two air-guiding air passages extending in different directions are formed on the periphery of the second air inlet; the cold-blast air is circulated along the air passages and around the inner container; the inner container is maintained at a low temperature for a long time; the condition that the rapid change of the temperature of the inner container occurs is avoided; the moisture of the food in the preservation chamber is also prevented from being taken away due to the circulation of the cold-blast air and further, the freshness of the food is ensured.

Description

technical field [0001] The invention belongs to the technical field of household appliances, and in particular relates to a fresh-keeping room and a refrigerator thereof. Background technique [0002] Refrigerators are indispensable household appliances in people's daily life. With the improvement of people's quality of life, the requirements for food preservation are also increasing. There are two main fresh-keeping methods in the existing refrigerator fresh-keeping technologies. One is The fresh-keeping room is set in the refrigeration room, and the fresh-keeping room is cooled by using the direct cooling space of the refrigeration room. Although it is guaranteed that the food moisture in the fresh-keeping room will not volatilize in large quantities, the disadvantage is that the cooling speed is slow and it is easily disturbed. The temperature in the fresh-keeping room cannot be maintained uniformly; the other is to set the fresh-keeping room in the refrigeration room, an...

[0002] Refrigerators are indispensable household appliances in people's daily life. With the improvement of people's quality of life, the requirements for food preservation are also increasing. There are two main fresh-keeping methods in the existing refrigerator fresh-keeping technologies. One is The fresh-keeping room is set in the refrigeration room, and the fresh-keeping room is cooled by using the direct cooling space of the refrigeration room. Although it is guaranteed that the food moisture in the fresh-keeping room will not volatilize in large quantities, the disadvantage is that the cooling speed is slow and it is easily disturbed. The temperature in the fresh-keeping room cannot be maintained uniformly; the other is to set the fresh-keeping room in the refrigeration room, and cool down by supplying cold air from the evaporator to the fresh-keeping room. The method is very easy to volatilize the moisture in the food, especially when storing foods that require high freshness, such as fish and vegetables, the air-cooling method can easily cause the food to dry, thereby reducing the taste of the food, and it is easy to produce oxidative odor
