Ventilation door device and refrigerator provided with same

Abstract

The invention discloses a ventilation door device and a refrigerator provided with the same.The ventilation door device comprises a shell, a plurality of ventilation doors, a resetting component and apower component, wherein the shell is provided with a plurality of air ports; the ventilation doors are corresponding to the air ports and are in pivot joint with the shell; the ventilation doors areconstructed to be switched over between an air port opening position and an air port closing position; the resetting component often drives the ventilation doors to be at the air port closing position; the power component comprises a control gear cluster; the control gear cluster is provided with an output component; and through the output component, the power component indirectly drives a plurality of ventilation doors to be integrally switched over among a plurality of preset working states and kept under any preset working state, wherein the quantity of each of the air ports and the ventilation doors is m, the quantity of the preset working states is 2m, and when the output component rotates by 360 degrees / 2m once, the preset working state of integrity of a plurality of ventilation doors is switched over, so that generalization and diversification of the open-close state of the ventilation doors are realized, and stability and quickness of ventilation door switchover are enhanced.

Description

technical field [0001] The invention relates to the technical field of air path control, in particular to a damper device and a refrigerator having the same. Background technique [0002] In the related art, the air duct air supply system usually includes a plurality of air outlets, and each air outlet corresponds to a certain range of controlled areas. The wind speed, wind direction, temperature, humidity, and gas composition of each controlled area are individually regulated to achieve a series of special functions. [0003] In order to realize the above functions, usually an independent damper device is arranged at each air outlet, and each damper device includes a damper and a power system. There are following disadvantages in this scheme: [0004] 1) Each air outlet needs a damper device, and multiple air outlets require multiple damper devices. The scheme has complex structure, large space occupation and high cost; [0005] 2) Each damper device requires a power sy...

Problems solved by technology

This causes the starting current to be too large, requiring the use of a high-power power supply, which consumes a lot of power and is not energy-saving and environmentally friendly;

[0006] 3) Affected by the volume occupied by the device during actual work, the air duct air supply system using the device is bulky
