Below with reference to the refrigerator drainage arrangement of accompanying drawing description according to the embodiment of the invention.
As shown in Figure 1, the drainage arrangement 1 for refrigerator comprises according to the present invention: drainpipe 2, port flap 3 and overflow pipe 4.Drainpipe 2 comprises water inlet 201, discharge outlet 202 and the overfall between water inlet and discharge outlet 203.Port flap 3 is used for capping discharge outlet 202, and port flap 3 allows water from discharge outlet 202 discharges and forbids that gas enters in the drainpipe 2 from discharge outlet 202.One end of overflow pipe 4 links to each other with overfall 203 and the other end is provided with overflow valve 5, and overflow valve 5 allows water from described overflow pipe 4 discharges and forbids that gas enters in the drainpipe from described overflow pipe 4.
The drainage arrangement 1 that is used for refrigerator according to the present invention, allow water to discharge and forbid that gas enters in the drainpipe 2 from discharge outlet 202 from discharge outlet 202 owing to be provided with port flap 3 and port flap 3 in discharge outlet 202, therefore preventing the external heat humid air because refrigerator inside and ambient atmosphere pressure reduction enter refrigerator body inside along the blast pipe suck-back affects refrigerating efficiency.On the other hand, because being used for the drainage arrangement 1 of refrigerator, the present invention is provided with spout hole 203 and overflow pipe 4, when have a large amount of water to flow out in the refrigerator or discharge outlet 202 place's hydraulic pressure too high and when defrosting water can't be discharged from discharge outlet 202, can assist draining by spout hole 203 and overflow pipe 4, make the refrigerator draining more unobstructed.In addition, because also being provided with, overflow pipe allow water to discharge and forbid that gas enters overflow valve 5 in the drainpipe from described overflow pipe 4, therefore prevents that the external heat humid air from entering refrigerator body inside along overflow pipe 4 suck-backs, and affects refrigerating efficiency from described overflow pipe 4.
As shown in Figure 1, according to one embodiment of the invention, port flap 3 is for having the rubber sleeve of opening.
When have defrosting water from water inlet 201 when drainpipe 2 flows to discharge outlet 202 because the Action of Gravity Field of defrosting water, the rubber sleeve opening is opened, defrosting water is discharged from discharge outlet 202; When refrigeration for refrigerator, because the pressure differential of refrigerator inside and external atmosphere pressure, the rubber sleeve opening is in closure state, has sealed discharge outlet 202, prevents that therefore the external heat humid air from 2 entering refrigerator body from discharge outlet 202 along drainpipe.
According to one embodiment of the invention, overflow valve 5 comprises: drain plug 501, guide rod 502 and hydraulic pressure valve block 503.As shown in Figure 1, drain plug 501 is located in the other end of described overflow pipe and is provided with osculum 504, when osculum 504 is in closed state, and drain plug 501 sealing overflow pipes 4.Guide rod 502 is located in the overflow pipe 4.Hydraulic pressure valve block 503 is located on the guide rod and can moves along described guide rod 4 with buoyancy of water effect in the overflow pipe, to seal and to open osculum 504, namely in drainpipe 2 situation that the interior water yield is excessive or current are not smooth, current flow in the overflow pipe 4 from spout hole 203, hydraulic pressure valve block 503 moves up along guide rod 502 under the buoyancy of water effect, carries out draining thereby open osculum 504; And after the discharge of the water in the overflow pipe 4, because without buoyancy, hydraulic pressure valve block 503 moves down along guide rod 502, sealing drain plug 501 stops Hot wet air heating to enter.
Refrigerator according to the embodiment of the invention is described below.
Refrigerator according to the embodiment of the invention comprises: be limited with casing and the drainage arrangement of a chamber in it, drainage arrangement is the described drainage arrangement 1 for refrigerator of above-mentioned arbitrary embodiment, and the water inlet of the drainpipe of drainage arrangement 1 links to each other with drainpipe in the casing.
Other 26S Proteasome Structure and Functions according to the refrigerator of the embodiment of the invention are known to those skilled in the art, do not repeat them here.
Refrigerator according to the embodiment of the invention can prevent that Hot wet air heating from returning refrigerator refrigeration system from the exhaust apparatus suck-back, has therefore improved refrigeration for refrigerator efficient and defrost efficient.Refrigerator according to the embodiment of the invention can also be assisted draining by overflow pipe when a large amount of defrosting waters enter drainpipe, and overflow pipe also can prevent the Hot wet air heating suck-back.In the description of this specification, the description of reference term " embodiment ", " some embodiment ", " example ", " concrete example " or " some examples " etc. means to be contained at least one embodiment of the present invention or the example in conjunction with specific features, structure, material or the characteristics of this embodiment or example description.In this manual, the schematic statement of above-mentioned term not necessarily referred to identical embodiment or example.And the specific features of description, structure, material or characteristics can be with suitable mode combinations in any one or more embodiment or example.
