Technical field
The present invention relates to refrigerator arts, and in particular to a kind of equilibrated valve of wind cooling refrigerator.
Background technique
Refrigerator currently on the market is broadly divided into two kinds, direct cooling refrigerator and wind cooling refrigerator.Wind cooling refrigerator inner space is big, no
Can be internal damp as direct cooling refrigerator, constantly there is circulation cold air inside wind cooling refrigerator, internal smell can keep lasting
It is pure and fresh.But wind cooling refrigerator is there is also some problems, and since wind cooling refrigerator on refrigerating-chamber door using making ice, freezing chamber need to be arranged to cold
Supply air duct and return airway on Zang Shimen, but because the pressure drop in air duct and the sealing reason in air duct will cause air-supply wind
Amount is greater than return air air quantity, and in this way in freezing compartment and extraneous generation pressure difference, freezing compartment forms negative pressure relative to the external world, extraneous
Humid air can penetrate into freezing compartment by gasket causes condensation icing or frosting, causes Customer Complaint.But it is if straight
Refrigerator is in communication with the outside to come equilibrium freezing compartment and extraneous pressure are connect, and will lead to thermal insulation property decline, cooling capacity leakage, ice
Case energy consumption increases, performance decline.
Summary of the invention
In order to solve the technical problems existing in the prior art, the embodiment of the present application discloses a kind of pressure of wind cooling refrigerator
