Circulated air channel of three-door refrigerator

Abstract

The invention discloses a circulation air channel of a three-door refrigerator, which comprises the following parts: a casing, an evaporator, a split chilling chamber and refrigerating chamber on the top of the casing, a temperature-change chamber on the bottom of the casing, wherein the temperature-change chamber is an integral big drawer type structure, and the chilling chamber is only equippedwith a evaporator, the chilling work, the refrigerating work, the temperature-change work use the evaporator commonly, the chilling chamber, the refrigerating chamber and the temperature-change chamber are equipped with the circulation air channel adjusted the temperature with the same evaporator. The invention saves a temperature-change evaporator by adjusting the needed temperature of the intake air quantity in every chamber space with the circulation air channel, which preferably achieves temperature-change function lonely because the temperature chamber is a lone chamber, achieves the bigchilling and refrigerating conversion, meets the users' needs, provides the simple process, the convenient repairing.

Description

technical field [0001] The invention relates to a refrigerator, in particular to a circulating air duct of an air-cooled three-door refrigerator. Background technique [0002] Common refrigerators and freezers generally refer to double-door double-temperature, three-door three-temperature, and cabinet-type multi-door refrigerators. It has an independent outer door of the freezer, and the volume of the freezer is also relatively large, about 1 / 4 to 1 / 2 of the total volume, which can store more frozen food. Some refrigerators also have compartments and doors so that they can be stored separately according to different storage temperatures of food. [0003] Solenoid valves are commonly used in refrigeration systems such as refrigerators to control the flow of refrigerant, and supply refrigerant to each refrigerating (freezing) room to cool each space of the refrigerator to the required temperature. The refrigerant supplied to the refrigerating and freezing chambers is control...

AI Technical Summary

Problems solved by technology

[0006] Ordinary side-by-side refrigerators, the cold room is relatively narrow, not suitable for storing large trays, and cannot meet the requirements of American users for large and wide cold rooms

[0007] Ordinary side-by-side refrigerators generally do not have a variable temperature room. Even if there is, it is placed in the bottom of the cold room, and the temperature changing function from cold storage to soft freezing to freezing cannot be realized. It can only be adjusted between cold storage and soft freezing. The minimum temperature is - Around 8°C, which cannot meet the needs of users, especially American users
