The refrigeration cycle includes a compression process, a condensation process, an expansion process and an evaporation process, and provides cold or heat to the indoor space through the heat absorption and heat release process of the refrigerant to achieve temperature regulation of the storage space. The compressor compresses the refrigerant gas into a high-temperature and high-pressure state and discharges the compressed refrigerant gas, and the discharged refrigerant gas flows into the condenser. The condenser condenses the compressed high-temperature and high-pressure gaseous refrigerant into a liquid refrigerant, and the heat is released to the surrounding environment through the condensation process. The liquid refrigerant flowing out of the condenser enters the expansion valve, and the expansion valve expands the liquid refrigerant in the high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid refrigerant. The low-pressure liquid refrigerant flowing out of the expansion valve enters the evaporator, and the liquid refrigerant absorbs heat when flowing through the evaporator and evaporates into a low-temperature and low-pressure refrigerant gas, and the refrigerant gas in a low-temperature and low-pressure state returns to the compressor. The evaporator can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the refrigerator 100 can adjust the temperature of the storage space.

[0070] With the rapid development of refrigerators 100, people are placing more and more foods that need to be stored at different temperatures in the refrigerator 100, and sometimes eggs need to be stored in different temperature zones.

[0071] There are many types of eggs, and different eggs have different optimal refrigeration temperature zones. Hot spring eggs need to be stored at a lower temperature, usually between 2°C and 5°C, to ensure that the yolk does not undergo crystallization changes while maintaining its unique taste, while raw eggs need to be stored in a slightly higher temperature range, usually between 5°C and 10°C, to keep them safe for consumption.

[0072] The door body 21 is provided with a shelf for placing eggs, and the shelf is provided with a plurality of circular placement openings 612. The eggs are placed on the shelf, and when the door body 21 is closed, the eggs are refrigerated in the refrigeration chamber to achieve low temperature storage of the eggs.

[0102] When the heating element is at the lower side of the bottom wall of the drawer 61, the heat emitted by the heating element is first conducted to the bottom wall of the drawer 61, and the bottom wall of the drawer 61 transfers the heat to the objects or airflow in contact with the drawer bottom wall 611, so that the airflow close to the drawer bottom wall 611 is heated first. After the airflow is heated, the density becomes smaller, and it flows slowly upward from the bottom of the drawer 61, so that the hot airflow can gradually fill the second temperature control zone 642, so that the heating effect of the second temperature control zone 642 is better, and the heating efficiency of the second temperature control zone 642 is higher, so as to facilitate the preservation of eggs.

[0103] In some embodiments of the present application, the drawer 61 includes a drawer bottom wall 611 away from the top plate 22, and at least two circular placement openings 612 are formed on the drawer bottom wall 611. The placement openings 612 are provided with a curved annular wall 613 extending in a direction away from the drawer cover plate 62, and the multiple curved annular walls 613 are connected by connecting plates 614.

[0104] The eggs can be placed in the placement opening 612 on the drawer bottom wall 611 and placed in the curved annular wall 613. The curved annular wall contacts the shell of the egg so that the egg is fixed in the placement opening 612 and will not roll around in the drawer 61, thereby reducing the probability of the egg breaking when the drawer 61 moves.

[0105] In some embodiments, the bottom wall of the curved annular wall 613 also has an opening to allow the tip of the egg to pass through the opening, thereby better fixing the egg and preventing the stress on the tip of the egg from being concentrated, thereby reducing the possibility of the egg breaking.

[0106] A plurality of placement openings 612 are arranged in an array on the drawer bottom wall 611 to arrange the eggs more neatly. A curved annular wall 613 is provided at each placement opening 612. In order to increase the strength of the curved annular wall 613, a plurality of connecting plates 614 are usually arranged between the curved annular wall 613. The connecting plates 614 act as reinforcing ribs. There are two types of connecting plates 614, one extending along the front-to-back direction and the other extending along the left-to-right direction, so that the curved annular wall 613 is subjected to force all around, thereby increasing the strength of the curved annular wall 613.

[0107] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
