Abstract
The invention relates to an air door for a refrigerator. The air door comprises a rotating shaft, an air door connecting plate and an air door. The air door is characterized in that a waterproof film is pasted at the back side of the air door, and the waterproof film is made of anti-freeze cotton. In the invention, the waterproof film is pasted at the back side of the air door, thus steam generated in the using process cannot remain on the surface of the air door, and frosting cannot be generated on the back side of the air door and water residues are difficult to generate, thereby the problem of frosting is solved, the normal opening, closing and using of the refrigerator air door are guaranteed, and the control precision of the refrigerator is improved.
Description
Technical field
The present invention relates to a kind of household electrical appliance assembly, specifically relate to the air door that a kind of refrigerator is used, belong to household electrical appliances and similar applications automatic controller field.
Background technology
Present refrigerator is divided into refrigerating chamber and two zones of refrigerating chamber usually, separate with dividing plate each other, the fan room that in the rear wall of refrigerator, is provided with evaporimeter and is communicated with evaporimeter, between freezer compartment of refrigerator and refrigerating chamber, be provided with the air-out air channel that links to each other with fan room, the air-out air channel between refrigerator in the chamber along separate routes after respectively with refrigerating chamber and refrigerating chamber UNICOM, fan will directly be blown in refrigerating chamber and the refrigerating chamber by the air-out air channel through the cold air of evaporator cools.For control refrigerating chamber, refrigerating chamber refrigeration, be provided with air door in the air-out air channel before along separate routes.Because the temperature difference between air-out air channel and refrigerating chamber is bigger, when refrigerating chamber stops to freeze, the higher relatively air of temperature in the refrigerating chamber can be back in the air-out air channel, when the air that refluxes runs into the lower cold air of temperature at damper positions, easily in the frosting of the back side of air door, after the frosting of the air door back side, can cause the air door dyskinesia, influence the aperture of air door, be easy to generate the slit after the closure, cause the cold air of refrigerating chamber to enter refrigerating chamber always and make fresh-keeping food freezing easily.Can make air door out of control under the serious situation, make refrigerator not be the refrigerating chamber refrigeration as requested, the control accuracy of refrigerator descends.
Summary of the invention
For solving the deficiencies in the prior art, purpose of the present invention is taken notice of provides a kind of wind door of refrigerator that solves the problem of the easy frosting in the air door back side in the refrigerator use.
For achieving the above object, the present invention is achieved by the following technical solutions:
1, a kind of wind door of refrigerator comprises turning cylinder, air door connecting plate and air door, it is characterized in that posting waterproof membrane at the back side of described air door.
2, wind door of refrigerator according to claim 1 is characterized in that described waterproof membrane is antifreeze cotton.
The invention has the beneficial effects as follows: the present invention posts waterproof membrane at the back side of air door, in use the aqueous vapor of Chan Shenging does not stop on the air door surface, the air door back side can not produce frosting, be not easy the residual of water, solved the problem of frosting, guarantee the normal switching and the use of refrigerator air door, improved the precision of refrigerator control.
Description of drawings
Fig. 1 is a wind door of refrigerator structural representation of the prior art;
Fig. 2 is the wind door of refrigerator structural representation among the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done concrete introduction.
Fig. 2 is the structural representation of the wind door of refrigerator among the present invention.As shown in the figure, wind door of refrigerator of the present invention, similar with present existing air door structure, comprise air door 1, turning cylinder 2 and air door connecting plate 3, be connected by turning cylinder 2 between air door connecting plate 3 and the air door 1, post waterproof membrane 4 at the back side of air door 1.Waterproof membrane 4 is mainly used in and prevents to form frosting.
Described waterproof membrane 4 can adopt materials such as antifreeze cotton, can use so long as can play the material of waterproof effect.
The present invention pastes waterproof membrane by the behind at air door, can prevent that the aqueous vapor that in use produces from stopping on the air door surface, the air door back side can not produce the phenomenon of frosting, be not easy the residual of water, so also just solved the problem of air door frosting, having prevented does not have the slit because frosting influences throttle opening after the air door closure, and the cold air of refrigerating chamber can not enter refrigerating chamber makes the food of insurance freezing.Guaranteed that refrigerating chamber can freeze as requested, has improved the control accuracy of refrigerator.
The foregoing description does not limit the present invention in any form, and all employings are equal to the hungry mode of replacement or equivalent transformation, and described technical scheme all drops in protection scope of the present invention.
Claims (2)
1. wind door of refrigerator comprises turning cylinder, air door connecting plate and air door, it is characterized in that posting waterproof membrane at the back side of described air door.
2. wind door of refrigerator according to claim 1 is characterized in that described waterproof membrane is antifreeze cotton.
