Abstract
The utility model provides a refrigerator with an automatic decompressor, which comprises a refrigerator body, and is characterized in that the refrigerator body is provided with an automatic decompressor, wherein the automatic decompressor comprises an air inlet passage which extends into the refrigerator body, the outer end of the air inlet passage is provided with a housing, the housing is provided with an air inlet, and the air inlet is provided with a movable closing door which can blow the air in a single direction. When the refrigerator door is opened, the outer hot air can enter the refrigerator, and after the door is closed, the hot air inside the refrigerator body is cooled down and retracted, so the pressure intensity is reduced to cause difficult opening of the refrigerator door at the next time. The automatic decompressor adjusts the pressure inside and outside the refrigerator so as to balance the pressure inside and outside the refrigerator, so the refrigerator door canbe easy to open at next time. The refrigerator with the automatic decompressor has reasonable structure and low production cost.

The utility model compared with prior art has many advantages and good effect:
1, the utility model is provided with an automatic pressure-reducing device at the refrigeratory body back, and the door body is opened, and enters hot-air in the refrigerator, and the hot-air that leaves in the door body closed condition refrigerator descends rapidly because of the temperature that influences that is subjected to refrigeration system, and therefore, air can be compressed in the refrigerator.Air compression back is because inside and outside differential pressure is opened the movable closing door of automatic pressure-reducing device automatically, and outside air can flow in the refrigerator from inlet channel, is in parastate up to pressure.Therefore, open the door than being easier to.
2, of the present utility model simple in structure, easy to make, cost is lower, is convenient to promote.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail:
Referring to Fig. 1-Fig. 4, a kind of embodiment with refrigerator of automatic pressure-reducing device, at refrigerator body 1 back (or sidepiece or top) automatic pressure-reducing device is set, automatic pressure-reducing device comprises the inlet channel 9 that stretches into refrigerator body 1 inside, inlet channel 9 outer ends are provided with a case, and described case is that the circle that is formed by circumference side and box bottom surface is box-like, and by the lid 2 that is threaded, the box bottom surface is communicated with 9 with described inlet channel, and an air inlet 6 is set below inlet channel 9 on the box bottom surface.Described air inlet 6 is semicircle, and air inlet 6 top margins are straight flange, and the movable closing door 5 of a size greater than the semicircle unidirectional air intake of air inlet 6 arranged, and on movable closing door 5 lateral surfaces circular arc convex edge 3 are set, to gain in weight good sealing effect.2 hooks 7 are set on the medial surface above the box bottom surface of the case air inlet 6, and movable closing door 5 hangs on the described hook 7 by 2 each link 10 that are provided with on the top margin in case.
The box bottom surface of described case is near refrigerator body 1 back side, and the setting that turns forward, and the box bottom periphery is provided with bulge loop 8, and groove 4 is set on the bulge loop 8, and described bulge loop 8 tops lean against on refrigerator body 1 back side.
Described inlet channel 9 is square straight-tube shape, and the axis of inlet channel 9 and box bottom surface are 95 ° of-110 ° of angles, and the axis of inlet channel 9 is vertical with refrigerator body 1 back side.Described case and inlet channel 9 are the integral structure of injection mo(u)lding.
Operation principle:
The cold air that refrigerator inside and external pressure were in parastate inside when 1, usual state refrigerator normally moved passes through case, direction moves shown in Fig. 1 arrow, but because the movable closing door 5 of inlet channel 9 is in closed state, so can not flow out to the product outside.
2, refrigerator door open state, because enter a lot of hot-airs, temperature fundamental sum ambient temperature is the same in the refrigerator when opening the door.Pressure also is in parallel state with the external world.
3, door body closed condition, the hot-air that leaves in the refrigerator descends rapidly because of the temperature that influences that is subjected to refrigeration system, and therefore, air can be compressed in the refrigerator.Outside air direction shown in Fig. 2 arrow in air compression back flows into.At this moment, because the pressure differential relation, the movable closing door 5 of inlet channel 9 is in opening, and like this, extraneous air can flow in the refrigerator by the movable closing door 5 of inlet channel 9, is in parastate up to pressure.By above action, internal pressure of refrigerator can form parastate with the external world, therefore, opens the door than being easier to.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of having done, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
