Refrigerator and air passage system thereof

Abstract

The invention provides a refrigerator and an air passage system thereof, wherein the air passage system comprises a main air passage and a refrigerating air passage, one end of the main air passage communicates with the air supply outlet of a refrigerating fan of the refrigerator, the second end of the main air passage is provided with a refrigerating port, and an electric damper assembly is arranged in the main air passage; the refrigerating air passage is provided with an air inlet, a first air outlet and second air outlet, the air inlet communicates with the refrigerating port, the first air outlet and the second air outlet is arranged in a refrigerating chamber of the refrigerator, and the refrigerating air passage communicates with the refrigerating chamber via the first air outlet and the second air outlet; an adjustor is arranged at the first air outlet, and is used for adjusting the air outlet area of the first air outlet. By means of the air passage system provided by the invention, a user can control the local temperature in the refrigerating chamber according to requirement, so the refrigerating chamber has the function of a variable-temperature chamber in the refrigerator product, and the product can better meet the different requirements of users.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a refrigerator and an air duct system thereof. Background technique [0002] At present, since the variable room of the refrigerator has a wide temperature range, and the temperature in the variable room is mostly between the refrigerator and the freezer, the use of the variable room is more flexible and more convenient during the daily use of the product. It can adapt to the different needs of users. However, the size of the temperature-changing room, refrigerating room and freezing room of existing refrigerators is relatively fixed, and in existing refrigerator products, the volume of the changing room is generally smaller than that of the refrigerating room and freezing room. In different occasions, the demand for the size of the variable greenhouse is different. Therefore, when the user has to store a large amount of food in the variable greenhouse, the setting of this str...

[0002] At present, since the variable room of the refrigerator has a wide temperature range, and the temperature in the variable room is mostly between the refrigerator and the freezer, the use of the variable room is more flexible and more convenient during the daily use of the product. It can adapt to the different needs of users. However, the size of the temperature-changing room, refrigerating room and freezing room of existing refrigerators is relatively fixed, and in existing refrigerator products, the volume of the changing room is generally smaller than that of the refrigerating room and freezing room. In different occasions, the demand for the size of the variable greenhouse is different. Therefore, when the user has to store a large amount of food in the variable greenhouse, the setting of this structure brings certain troubles to the user's use, thereby reducing the use of the product.
