Problems solved by technology

Usually, when defrosting, the compressor stops and the heat generated by the electric heater will cause the temperature in the refrigerator compartment to rise by 3-8°C, resulting in a change in the temperature of the stored food and affecting the quality of the food.

Embodiment Construction

[0045] figure 1 is a schematic side view of a refrigerator according to one embodiment of the present invention. see figure 1 , the refrigerator 10 of the embodiment of the present invention may include a storage compartment 12 and an evaporator 15 . figure 1 The illustrated refrigerator 10 has two storage compartments 12, and in an unillustrated embodiment, the refrigerator 10 may also have only one storage compartment or more than two storage compartments. As those skilled in the art can appreciate, in addition to the evaporator 15, the refrigerator 10 of the embodiment of the present invention is the same as the existing indirect refrigerator (or air-cooled refrigerator), and can also include a compressor 14 (not shown in the figure). Out), condenser (not shown in the figure), and throttling element (not shown in the figure), etc.

[0046] In particular, in the embodiment of the present invention, the refrigerator 10 may further include a liquid storage device 110 contai...

Abstract

The invention provides a refrigerator. The refrigerator comprises a storage chamber and an evaporator and further comprises a liquid storage device, an air return duct and an air supply duct, wherein the liquid storage device contains liquid-state fluid with the freezing point lower than a preset threshold value, and the evaporator is immersed in the liquid-state fluid; airflow from the storage chamber is guided into the liquid-state fluid through the air return duct and subjected to heat exchange with the liquid-state fluid so as to be cooled; and airflow penetrates through the liquid-state fluid to escape to the space above the liquid level of the liquid-state fluid is returned to the storage chamber through the air supply duct. According to the refrigerator, by arranging the evaporator in the liquid-state fluid with the low freezing point, the problem of frosting of the evaporator of the refrigerator can be solved, the evaporator can operate in a frost-free mode continuously, the performance of a refrigerating system is improved, and energy consumption is reduced. Meanwhile, the situation that temperature fluctuation of the storage chamber of the refrigerator is large due to defrosting of the evaporator can be avoided.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a frost-free refrigerator. Background technique [0002] After a period of use of the direct cooling refrigerator, there will be frosting in the compartment inside the box. To solve this problem, an indirect cooling refrigerator has been developed. The cold air from the evaporator cools the compartment inside the box. Since the air-conditioning temperature is always lower than the room temperature, there is no problem of frosting. [0003] The intercooler refrigerator solves the problem of frosting in the refrigerator very well, but the surface of the evaporator of the indirect refrigerator will frost after a period of use. As the amount of frost on the evaporator increases, the cooling efficiency of the refrigerator will decrease, which will affect the temperature of the refrigerator compartment. Temperature stability requires regular defrosting. At present, t...
