Description

A kind of refrigerator

Technical Field

The utility model relates to the technical field of household appliances, especially, relate to a refrigerator.

Background

The refrigerator mainly realizes the food storage function by a refrigeration mode, the refrigerator is divided into two areas in temperature, the refrigeration area is about 4 ℃, the freezing area is about-18 ℃, although some refrigerators have temperature change areas, a single temperature change area cannot meet the storage requirements of various food materials with different storage conditions, and some food materials need to be stored in a single area.

Currently, there are multiple types of products on the market that store different items:

for example, the cosmetic refrigerator is set at about 10 deg.C, and can be used for storing cosmetics or facial masks containing active substances such as VC and retinol, which need to be stored at low temperature and in dark place. The refrigerating temperature of the refrigerator is too low, some masks are directly used at the refrigerating temperature, the skin of a user with sensitive skin is not suitable, and skin problems such as red blood streak and the like occur.

For food materials such as tea, tea has strong moisture absorption and odor absorption, is easy to absorb moisture and peculiar smell in air, and needs relatively independent storage space. Some tea leaves are low in temperature environment, especially fermented tea such as green tea, and the storage temperature of the green tea is controlled below 10 ℃ and the relative humidity is controlled below 50% according to GB/T30375-2013.

If some tropical fruits need to be stored at a temperature higher than the refrigerating temperature, the optimal storage temperature of the tropical fruits is different due to different types, and some tropical fruits are not suitable for being placed in a refrigerator, for example, the optimal storage temperature of mangos is about 10-13 ℃, and the peels can turn black when the temperature is lower than 8 ℃; the most suitable preservation temperature of the pawpaw is about 7 ℃; guava can be stored for 2-3 weeks at 5-10 deg.C, the temperature is lower than 5 deg.C, the pineapple without peel can be stored for one month at 11-13 deg.C, and it is easy to deteriorate when placed in refrigerator; the bananas are stored at the temperature of between 8 and 23 ℃ most suitably, the bananas are easy to be over-ripe and blackened at high temperature, and the bananas are easy to be frostbitten and blackened when the temperature is lower than 5 ℃; guava suffers from pulp damage and decay due to freezing.

Products such as cakes and bread are not suitable for being stored in a cold storage mode, and the cold storage mode can accelerate the aging of starch in the bread, so that the bread is dry, hard, rough and poor in taste. The starch retrogradation reaction is irreversible and once the bread becomes "old", it loses its original flavor even after reheating. At present, products such as ice bars/hall bars, pastry cabinets and the like exist in the market, the temperature areas are arranged in the refrigerator, the difference is large, and the storage requirements of users on food materials can be met.

However, the above products all appear with the function of realizing the storage of a certain kind of food materials, such as beauty cosmetics refrigerators, medicine cabinets, cake cabinets, wine cabinets, hall bars, mother and infant milk storage refrigerators and the like, and a user needs to buy 6 or more separate products at the same time when wanting to store beauty cosmetics, baked cakes, medicines, wine, tea leaves and the like separately. And sometimes, although a common user has a plurality of food materials with different storage conditions, the quantity of the food materials of a single category is not so large, and the space and money are wasted for purchasing a plurality of categories of products.

Therefore, a refrigerator integrating these kinds of functions in the same space is urgently needed, and various storage requirements are realized on the premise of saving space.

The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

The throttle valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the throttle valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The refrigerator can regulate the temperature of the space in the refrigerator throughout the cycle.
