Icebox and control method thereof

Abstract

The invention relates to an icebox and a control method thereof. The icebox comprises a box body, a box door, a refrigeration chamber evaporator, a refrigeration chamber blower and a freezing chamber evaporator, wherein a refrigeration chamber, a variable-temperature chamber, a freezing chamber and a refrigeration chamber duct are restricted in the box body, the variable-temperature chamber is arranged between the refrigeration chamber and the freezing chamber and separated from the refrigeration chamber by a variable-temperature chamber separator, the refrigeration chamber duct is arranged behind the refrigeration chamber, the upper end of the refrigeration chamber duct is communicated with the refrigeration chamber by an air outlet of the refrigeration chamber, the lower end of the refrigeration chamber duct is communicated with the variable-temperature chamber by an air return opening of the refrigeration chamber, the front side of the box body is provided with an opening which is opened or closed by the box door mounted on the box body, the refrigeration chamber evaporator is arranged outside the refrigeration chamber duct, the refrigeration chamber blower is arranged at the air outlet, and the freezing chamber evaporator is arranged in the freezing chamber. The icebox can satisfy the user requirement for sorting foods by kinds and storing foods by temperature areas and has simple structure, great storage space, sanitary food storage and low energy consumption, noise and production cost.

Description

technical field [0001] The invention relates to a refrigeration device, in particular to a refrigerator and a control method thereof. Background technique [0002] Mixed cooling refrigerators are also called direct air cooling refrigerators. The freezer usually adopts air cooling refrigeration, while the refrigerator adopts direct cooling refrigeration. Traditional two-door hybrid refrigerators generally only have two temperature zones, namely the refrigerator and the freezer. With the improvement of people's living standards, users put forward more requirements for the storage of food in the refrigerator. The traditional two-door, two-temperature zone mixed-cooler refrigerator can no longer meet the user's requirements for partitioning, classifying, and diversifying food storage. Different foods are prone to mutual odor. [0003] The three-door mixed-cooler refrigerator with a variable-temperature chamber was developed under such circumstances, but the structure, control a...

Problems solved by technology

With the improvement of people's living standards, users put forward more requirements for the storage of food in the refrigerator. The traditional two-door, two-temperature zone mixed-cooler refrigerator can no longer meet the user's requirements for partitioning, classifying, and diversifying food storage. Different foods are prone to odors from each other.

[0003] The three-door mixed-cooler refrigerator with a variable-temperature chamber was developed under such circumstances, but the structure, control and refrigeration system of the traditional three-door mixed-cooler refrigerator with a variable-temperature chamber are often more complicated. A traditional cooling method is: the variable-temperature chamber is To realize the cooling of the variable temperature room by setting the variable temperature room evaporator in the variable temperature room, it not only needs to reserve space for installing the evaporator, but also needs to increase the fan, which is not conducive to volume utilization and noise control; The air duct and the refrigeration method of introducing cold air from the freezer not only increase the cost, but also have a complicated structure, which is not conducive to manufacturing, and will cause the problem of food drying; moreover, the humid gas in the warming room will enter the freezer, resulting in frequent evaporators in the freezer. Frosting and defrosting are not good for energy consumption control

[0004] In addition, the cold room, freezer room and variable temperature room of the traditional three-door hybrid refrigerator with variable temperature room are opened and closed by three independent doors, so the processing and manufacturing are complicated and the cost is high

[0005] Moreover, since the refrigerating room adopts a direct cooling method, the evaporator of the refrigerating room is installed on the back wall of the refrigerating room, and the back wall of the refrigerating room is completely exposed in the refrigerating room, so small food particles are easy to enter with the defrosting water in the refrigerating room Drain outlet, causing blockage of drain pipes and overflow of defrosted water; in addition, food or food packaging is easily in contact with the back wall of the refrigerator, causing defrosted water to flow into the refrigerator along its surface and contaminate other foods
