Description of drawings
Fig. 1 is the structure chart that the discharge pipe line of the utility model refrigerator connects.
The specific embodiment
Referring to Fig. 1, a kind of refrigerator with air pressure balance drainage arrangement, the discharge pipe line that picks out in the refrigerator box body comprises the water inlet pipe 1 that is communicated with in an end and the refrigerator box body, water inlet pipe 1 stretches out standpipe 2 upper ends that the outer termination one of refrigerator box body is erect, the epimere of an outlet pipe 3 is inserted in standpipe 2 lower ends, and the hypomere of outlet pipe 3 is a S shape outlet pipe water storage curved 4.Have a S shape air inlet pipe 5 one ends to insert standpipe 2 lower ends, air inlet pipe 5 mouths of pipe in the standpipe 2 are lower than the upper port of outlet pipe 3, and curved 7 bottoms of the air inlet pipe water storage that S shape air inlet pipe 5 forms are higher than curved 4 tops of outlet pipe water storage.The internal diameter cross section of standpipe 2 is water inlet pipe 1, outlet pipe 3 and air inlet pipe 5 internal diameter cross sections 10-50 a times, and 5 air inlet places are provided with screen pack in air inlet pipe.
Operation principle:
1, the internal water of the utility model refrigerator flows into standpipe 2 by water inlet pipe 1, flow into outlet pipe 3 and air inlet pipe 5 then, when water level in the air inlet pipe 5 reaches the H1 height, all water will flow into drainpipe 3, form two water seals by air inlet pipe water storage curved 7 and curved 4 (height of water level is H4) of outlet pipe water storage like this, stop the hot and humid gas of outside to enter refrigerator inside, reduce the frosting of refrigerator, the power consumption of reduction refrigerator.
2, water inlet pipe 1 of the present utility model is connected with casing is interior, and outlet pipe 3 and air inlet pipe 5 communicate with the external world, when forming negative pressure in the refrigerator box body, and the pressure imbalance of the water seal both sides in outlet pipe water storage curved 4 and the air inlet pipe water storage curved 7, water can flow to standpipe 2 directions.
3, will flow into drainpipe 3 after the water in the air inlet pipe water storage of the present utility model curved 7 flows upward to the H1 height, the pressure that final air inlet pipe 5 intake requirements overcome is the pressure that the water column of H1-H2 height forms, because the external and internal pressure difference is much larger than this pressure, ambient atmos can overcome this pressure and enter refrigerator box body inside by air inlet pipe 5-standpipe 2-water inlet pipe 3, when refrigerator external and internal pressure difference had only the pressure of H1-H2 water column formation highly, no longer the door of refrigerator was opened in influence at last.Simultaneously, water seal in the outlet pipe water storage curved 4 also can be moved upward to H3 position even higher, the height of water column will be much larger than the H1-H2 height herein, if gas is want to enter in the refrigerator box body by outlet pipe 3, to overcome the pressure that manys bigger than air inlet pipe 5, therefore, gas will not enter in the refrigerator box body by outlet pipe 3.
If 4 sometimes in the casing pressure differential with extraneous very big, the intake velocity of air inlet pipe 5 can't be satisfied the demand, the water of water seal also can flow into standpipe 2 in the outlet pipe 3, because the inner section of standpipe 2 is long-pending is tens times that outlet pipe 3 inner section are amassed, therefore, the height of water level in the standpipe 2 is lower, and pressure is also lower, gas enters easily, also avoids water to enter water inlet pipe 1 simultaneously and oppositely flows in the refrigerator.Along with gas enters refrigerator, the air pressure in the refrigerator will with extraneous basically identical, will form water seal in the outlet pipe water storage curved 4, prevent that the damp-heat air in the external world from entering refrigerator.Because air inlet pipe 5 mouths of pipe enter the position H2 of standpipe 2, lower than the position H1 of outlet pipe 3 upper port, then, H2 will all flow in the air inlet pipe 5 to the water in the H1 in the standpipe 2, and curved 7 places form water seal at the air inlet pipe water storage.
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.
