Title:
REFRIGERATOR
Document Type and Number:
WIPO Patent Application WO/2021/129386
Kind Code:
A1
Abstract:
Disclosed is a refrigerator (100). The refrigerator (100) comprises a first fresh-preservation chamber (110), an adsorption tower (120), a valve (130), and an air pump (140). An air inlet of the air pump (140) is in communication with the first fresh-preservation chamber (110), an air outlet of the air pump (140) is in communication with an air inlet of the adsorption tower (120) by means of an air inlet channel of the valve (130), and the air inlet of the adsorption tower (120) is in communication with the first fresh-preservation chamber (110) by means of an air outlet channel of the valve (130); the air inlet channel of the valve (130) is opened, such that the air pump (140) pressurizes air in the first fresh-preservation chamber (110) to enable the air to be conveyed to the adsorption tower (120), the adsorption tower (120) filters out oxygen in the air, the oxygen is discharged from an air outlet of the adsorption tower (120), and residual gas is adsorbed; and the air inlet channel of the valve (130) is closed, such that the air pump (140) stops pressurizing air and conveying the air to the adsorption tower (120), the adsorption tower (120) releases the residual gas, and the residual gas is discharged into the first fresh-preservation chamber (110) via the air inlet of the adsorption tower (120) and the air outlet channel of the valve (130). The oxygen content of the first fresh-preservation chamber (110) can be reduced, and the fresh-preservation effect is improved.
