Refrigerator and separation embedded type air channel structure thereof

Abstract

The invention discloses a refrigerator and a separation embedded type air channel structure thereof. The separation embedded type air channel structure of the refrigerator comprises a refrigeration air channel and a temperature change air inlet channel communicating with the refrigeration air channel. The separation embedded type air channel structure further comprises a first temperature change air channel, a second temperature change air channel, a cold storage air inlet channel and a cold storage air channel. The first temperature change air channel and the second temperature change air channel are arranged in parallel, and the inlet end of the first temperature change air channel and the inlet end of the second temperature change air channel both communicate with the temperature change air inlet channel. The outlet end of the second temperature change air channel communicates with the cold storage air channel through the cold storage air inlet channel. A varying temperature air door is arranged in the first temperature change air channel. A cold storage air door is arranged in the cold storage air inlet channel. The cold storage air channel and the first temperature change air channel are arranged in a separation mode, and the varying temperature air door and the cold storage air door are arranged in the first temperature change air channel and the cold storage air inlet channel correspondingly, independent cold air control of a cold storage chamber and a temperature change chamber is achieved, and thus independent and precise temperature control over the cold storage chamber and the temperature change chamber is achieved.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a refrigerator and its discrete embedded air duct structure. Background technique [0002] The refrigerator compartments in the prior art are usually divided into a refrigerating room, a variable room and a freezing room. Since the refrigerating room and the variable room share a fan, the air duct of the refrigerating room is connected to the air channel of the variable room. When cooling the refrigerating room, the variable temperature The greenhouse is also refrigerated at the same time, and the temperature of the cold room and the temperature of the variable room will affect each other, so the temperature of the cold room and the variable room cannot be controlled separately, and the precise temperature control of the cold room and the variable room cannot be realized. [0003] Thereby prior art still needs to improve and improve. Contents of the invention [0004] In...
