Air duct device of refrigerator and full-variable-temperature refrigerator

Abstract

The invention discloses an air duct device of a refrigerator and the full-variable-temperature refrigerator. The air duct device comprises a front air duct cover plate, a front foam air duct, a rear foam air duct, two air doors, a rear air duct cover plate and a centrifugal fan assembly, wherein the front air duct cover plate is mounted on the wall of the inner chamber of the refrigerator; the front foam air duct is mounted on the front air duct cover plate; the rear foam air duct is mounted on the front foam air duct; the two air doors are mounted on the rear foam air duct; the rear air duct cover plate is mounted on the front air duct cover plate; an air duct is defined by the front air duct cover plate, the front foam air duct, the rear foam air duct and the rear air duct cover plate in a sealed manner; and the centrifugal fan assembly is positioned in the air duct, and is mounted on the front air duct cover plate. The air duct device and the full-variable-temperature refrigerator can control the storage temperatures of all chambers to achieve the function that the temperatures of all the chambers can be varied arbitrarily, so that the functions of a refrigeration chamber, a freezing chamber and a variable-temperature chamber can be defined according to own requirements by users.

Description

technical field [0001] The invention relates to an air duct device for a fully variable temperature refrigerator, in particular an air duct device capable of varying the temperature of multiple compartments of the refrigerator, and a refrigerator including the air duct device. Background technique [0002] In existing refrigerators, there are basically one or more refrigerated rooms, one or more freezer rooms, and one or more variable temperature rooms. Except for a single variable temperature room, all other rooms cannot be arbitrarily changed in temperature, that is, all rooms It cannot be interchanged, and it is impossible for users to define the functions of each room. As a result, in many cases, the storage space of some rooms is not enough, but some rooms are empty, which greatly reduces the utilization efficiency of the refrigerator. and flexibility. Contents of the invention [0003] The present invention aims to solve the problems and deficiencies in the prior ar...
