Abstract

The utility model relates to an air valve of the negative pressure reducing for opening a refrigerator door, which is mainly composed of a valve body (8), an opening handle (5), a Z-shaped transmission lever (12), wherein, the valve body (8) is mainly composed of an air inlet (14) and an air outlet (13), a cavity is arranged on a refrigerator sealing layer which is abutted on a handle (4), the valve body (8) is arranged in the cavity, the air outlet (13) of the valve body (8) penetrated through the sealing layer and an inner wall (6) of the refrigerator is exposed in the refrigerator, the opening handle (5) is arranged in the refrigerator handle (4), and a return spring (9) is arranged on the opening handle (5). When the utility model is used, the opening handle (5) is pressed, the left end with a sealing element (11) for the Z-shaped transmission lever (12) is separated from one end of the air inlet (14) of the valve body (8) which is connected with the left end, the air outside the refrigerator can enter the refrigerator through the air inlet (14), and the negative-pressure phenomenon in the refrigerator is eliminated.

Description

Refrigerator is opened the Reduction of Students' Study Load pressure valve

The utility model relates to a kind of air valve, and a kind of specifically refrigerator is opened the Reduction of Students' Study Load pressure valve.

At present, though refrigerator has good door envelope effect, but because refrigerator particularly is in low-temperature condition in the refrigerating chamber, the contraction because the hot-air that environment enters is caught a cold rapidly, cause and be negative pressure state in the case, like this door of refrigerator just extremely difficulty open, often owing to open the door firmly excessive, break or draw the damage handle, the door closure surface often produces convex-concave and alternately changes, and the case mouth plane of outer wall of case and pressure that gasket seals also is subjected to influence in various degree, and gasket is crushed with the door closure extruding, elasticity weakens, and influences its insulation effect.

The purpose of this utility model is to provide a kind of unlatching Reduction of Students' Study Load pressure valve that the refrigerator lid is opened of being convenient to.

The technical solution of the utility model is: refrigerator is opened the Reduction of Students' Study Load pressure valve and mainly is made up of valve body, unlatching handle, " Z " shape transmission levers, valve body mainly is made up of air inlet, gas outlet, the employing soft rubber material is made, refrigerator digs a cavity near the sealant of handle, air valve places in the cavity, it is characterized in that: the valve body gas outlet passes sealant and the refrigerator inwall exposes in the refrigerator, opening handle places in the refrigerator handle, open on the handle back-moving spring is housed, the contacted end of the air inlet of " Z " shape transmission levers and valve body is equipped with seal.The utility model is simple in structure, and cost is low, easy to assembly, uses it to open the refrigerator door closure easily, to prolong the service life of refrigerator.

Fig. 1 is a main TV structure schematic diagram of the present utility model.

Fig. 2 is a valve body structure schematic diagram of the present utility model.

Below in conjunction with embodiment and contrast accompanying drawing the utility model is described further.Valve body of the present utility model can adopt soft rubber material to make, open handle [5], the one end passes a limit and exposes to outside the refrigerator, the other end is provided with circular hole [3], " Z " shape transmission levers [5] right-hand member also is provided with circular hole [7] and the small sircle hole [10] identical with circular hole [3] diameter, the other end that to open handle [5] with bolt connects with the right-hand member of transmission levers [12] is folded mutually, the left end of " Z " shape transmission levers [12] contacts with the air inlet [14] of valve body [8] by being bolted on the refrigerator inwall [6] and seal [11] being housed, the fixed mount of back-moving spring [9] is fixed on the just preceding power of " Z " shape transmission levers [12] right-hand member, maintains an equal level with " Z " shape transmission levers [12] left end.The other end of back-moving spring [9] places in " Z " shape transmission levers [12] right-hand member small sircle hole [10].Valve body [8] is L-shaped, and part is exposed rectangle gas outlet [13] anyhow, and the vertical portion is divided into circular air inlet [14].Valve body [8] places by a fixed mount in the sealant cavity of refrigerator, the hole that has the gas outlet [13] of its diameter and valve body [8] to adapt on sealant and the inwall [6], and the gas outlet [13] of valve body [8] is then passed this hole and is exposed in the refrigerator.During use, press and open handle [5], " Z " shape transmission levers [12] has the left end of seal and the contacted end of air inlet [14] of valve body [8] opens with it, the outer air of refrigerator just can enter in the refrigerator by air inlet [14], eliminated the negative pressure appearance in the refrigerator, the refrigerator door closure has also just been opened easily.

Claims

1, a kind of refrigerator unlatching Reduction of Students' Study Load pressure valve mainly is made up of valve body [8], unlatching handle [5], " Z " shape transmission levers [12], valve body [8] adopts soft rubber material to make, refrigerator digs a cavity near the sealant of handle, valve body places in the cavity, it is characterized in that: valve body [8] gas outlet [13] passes sealant and refrigerator inwall [6] exposes in the refrigerator, opening handle [5] places in the refrigerator handgrip [4], open on the handle [5] back-moving spring [9] is housed, " Z " shape transmission levers [12] is equipped with seal [11] with the contacted end of air inlet [14] of valve body [8].
