In description of the invention, need to prove that unless clear and definite regulation and qualification are arranged in addition, term " installation ", " linking to each other ", " connection " should be done broad understanding, for example, can be fixedly connected, connect integratedly, also can be to removably connect; Can be mechanical connection or electrical connection, also can be the connection of two element internals; Can be directly to link to each other, also can link to each other indirectly, for the ordinary skill in the art, can understand the concrete implication of above-mentioned term as the case may be by intermediary.
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 that is used for refrigerator according to the present invention comprises: 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 permission water are from discharge outlet 202 discharges and forbid 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 permission water are from described overflow pipe 4 discharges and forbid 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 are gone into refrigerator body inside along the blast pipe suck-back influences 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 make the defrost water can't be when discharge outlet 202 is discharged, can assist draining by spout hole 203 and overflow pipe 4, make the refrigerator draining more unobstructed.In addition, allow water to discharge and forbid that gas enters overflow valve 5 in the drainpipe from described overflow pipe 4, prevent that therefore the external heat humid air from going into refrigerator body inside along overflow pipe 4 suck-backs, and influence refrigerating efficiency from described overflow pipe 4 because overflow pipe also is provided with.
As shown in Figure 1, according to one embodiment of the invention, port flap 3 is for having the rubber sleeve of opening.As defrost water from water inlet 201 when drainpipe 2 flows to discharge outlet 202 because the gravity effect of defrost water, the rubber sleeve opening is opened, defrost water is discharged from discharge outlet 202; When refrigerator freezed, because the pressure differential of refrigerator inside and external atmosphere pressure, the rubber sleeve opening was in closure state, has sealed discharge outlet 202, prevented 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, promptly under the situation that the water yield is excessive or current are not smooth in the drainpipe 2, current flow in the overflow pipe 4 from spout hole 203, hydraulic pressure valve block 503 moves up at buoyancy of water effect lower edge guide rod 502, carries out draining thereby open osculum 504; And after the discharge of the water in the overflow pipe 4, because no buoyancy, hydraulic pressure valve block 503 moves down along guide rod 502, and sealing drain plug 501 stops hot humid air 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 the casing and the drainage arrangement of a chamber in it, drainage arrangement is the described drainage arrangement 1 that is used 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 humid air from returning refrigerator refrigeration system from the exhaust apparatus suck-back, has therefore improved refrigerator refrigerating efficiency and defrost efficient.Refrigerator according to the embodiment of the invention can also be assisted draining by overflow pipe when a large amount of defrost water enter drainpipe, and overflow pipe also can prevent hot humid air suck-back.In the description of this specification, concrete feature, structure, material or characteristics that the description of reference term " embodiment ", " some embodiment ", " example ", " concrete example " or " some examples " etc. means in conjunction with this embodiment or example description are contained at least one embodiment of the present invention or the example.In this manual, the schematic statement to above-mentioned term not necessarily refers to identical embodiment or example.And concrete feature, structure, material or the characteristics of description can be with the suitable manner combination in any one or more embodiment or example.
Although illustrated and described embodiments of the invention, those having ordinary skill in the art will appreciate that: can carry out multiple variation, modification, replacement and modification to these embodiment under the situation that does not break away from principle of the present invention and aim, scope of the present invention is limited by claim and equivalent thereof.
