Description
Technical field
The present invention relates to freezing and refrigeration technology, more particularly to a kind of refrigerator.
Background technology
Existing wind cooling refrigerator typically may include underlying refrigerating chamber and cold room above and
Circulation air path.Circulating current for cold room typically leads to base of evaporator from the air outlet of cold room, cold
The return air hiding room is passed through from evaporator fin, thus by vaporizer cooling refrigeration, being then blown to by blower fan
Cold room is freezed.This circulating current, when flowing out the air outlet of cold room, has taken away the moisture in food,
Made by evaporator refrigeration, the frosting on the surface of vaporizer of the moisture in cold air.Cumulative frost is serious
Have impact on the heat transfer of vaporizer, reduce refrigerator operational efficiency, so when present wind cooling refrigerator will run one section
Between after shut down defrost, the frequent shutdown defrost of refrigerator considerably increases energy consumption.Additionally, the system through vaporizer
Cold freeze after air, when being blown into cold room again, due to being lowered the temperature dehumidifier by vaporizer, air has compared
It is dried, when sending into cold room, will be very low for the humidity leading to cold room, the food dehydration preserving can be air-dried,
Fresh-keeping very unfavorable to food.
In order to solve above-mentioned technical problem, return air inlet can be increased on the return airway of wind cooling refrigerator, make one
Cold room return air is divided to cool down without vaporizer and enter next air-supply circulation.This mode can be in certain journey
Reduce evaporimeter frosting on degree, slow down the air-dried degree of food, however, passing through to increase that of return air inlet introducing
The mistake that partly hot and humid gas is mixed in blower fan or its elsewhere with the gas of the cold drying through vaporizer
It is easy to the problem of frosting or icing occurs at blower fan or other mixing in journey, lead to rotation speed of fan
Reduce, finally cause cold room, freezer temperature imbalance.

Specific embodiment
Fig. 1 is the schematic diagram of refrigerator according to an embodiment of the invention, and Fig. 2 is along along Fig. 1
The schematic cross sectional views that cutting line A-A intercepts.Referring to Fig. 1 and Fig. 2, refrigerator 1 includes cooler 10, case
Body 20 and drainage plate 30.Specifically, cooler 10 is configured to and flows through its gas carry out heat exchange, from
And change the temperature of this gas.Cooling chamber 21 and exhaust air flue 22, wherein cooler is defined in casing 20
10 are arranged in cooling chamber 21, and cooling chamber 21 has along the gas flow direction connection in cooling chamber 21
The first return air inlet 211 and the second return air inlet 212 being communicated to cooler 10 downstream to cooler 10 upstream.
Return airway 22 is communicated to the first return air inlet 211 and the second return air inlet 212.Drainage plate 30 is located at cooling chamber
In 21 and be arranged so that through the second return air inlet 212 enter the gas of cooling chamber 21 with through the first return air inlet
At least part of gas of the 211 entrance cooled devices 10 of cooling chamber 21 cocurrent mixes at drainage plate 30.Thus,
After hot and humid gas through the second return air inlet 212 entrance cooling chamber 21 and cooled device 10 heat exchange at least
Part cold drying gas can mix at drainage plate 30 in advance.In mixed process, hot and humid gas
Temperature reduces, and the saturability of gas declines, and unnecessary moisture separates out, and frosting at drainage plate 30,
Frosting at miscellaneous part in cooling chamber 21 is thus avoided its performance to be impacted, thus improve refrigerator 1
Serviceability.In embodiments of the present invention, cooler 10 is preferably vaporizer, with to flowing through its gas
Body is cooled down.In present invention others embodiment, cooler 10 can also change for other kinds of
Hot device.
In some embodiments of the invention, it is further defined with least one in casing 20 for storing article
Storing compartment, each storing compartment is all connected with return airway 22, with by return airway 22 to cooling chamber
21 conveying return air.Further, may also define connection cooling chamber 21 and the sending of storing compartment in casing 20
Wind air channel, so that storing compartment is sent to by supply air duct by the gas that cooler 10 cools down, thus,
Form cooling to follow between the storing compartment in casing 20, return airway 22, cooling chamber 21 and supply air duct
Ring.
Further, at least one storing compartment may include refrigerator room (not shown) and freezing compartment
23, cooling chamber 21 is located at after freezing compartment 23.Designated herein it is followed by being in normally with refrigerator 1
For under use state.Refrigerator room and freezing compartment 23 can neighbouring be arranged, and have not inside it
Same temperature range, to realize the object storing of different demands.Cooling chamber 21 and freezing compartment 23 can be front
Horizontal direction afterwards is disposed adjacent.It will be understood by those skilled in the art that in present invention others embodiment,
At least one storing compartment may also include quick-freezing compartment, alternating temperature compartment and/or ice making compartment etc., different storing
Compartment has different temperature ranges, to be stored to different article and/or to be realized different storages to need
Ask.

Top and between cooler 10 and blower fan 40, the first air outlet 211 is located under cooling chamber 21
Portion and in the gas flow direction in cooling chamber 10 be located at cooler 10 upstream.Implement in the present invention
In example, the gas flow direction in cooling chamber 21 is from down to up, the gas flowing side in return airway 22
To for from top to bottom, specifically shown in visible Fig. 1 cathetus arrow.
In the refrigerator 1 of the present invention, the portion gas for circulation cool down without cooler 10, and in cooling
The downstream of device 10 is mixed with least part of gas flowing through cooler 10, to reach cryogenic temperature, and
Corresponding storing compartment (such as cold preservation can be continued back to without the moisture in the gas of cooler 10 cooling
Compartment) in.Therefore, at least part of moisture in refrigerator room can be avoided in cooler 10 while refrigeration
Upper frosting, decreases the frosting degree on cooler 10, make defrosting cycle elongated or single defrosting time
Shortening, thus reducing the power consumption of refrigerator 1, making refrigerator 1 more energy-conservation.
In some embodiments of the invention, drainage plate 30 can be from the second return air inlet 212 to cooling chamber 21 in
Extend, so that drainage plate 30 is located at blower fan 40 and cooling in the gas flow direction in cooling chamber 21
Between device 10, and make via the second return air inlet 212 gas in drainage plate 30 towards cooler 10
A side inflow cooling chamber 21.That is, for for being drained to cooling chamber via the second return air inlet 212
21 gas and the Mixed Zone being mixed via at least part of gas after cooler 10 heat exchange are located at and draw
The side towards cooler 10 of stream plate 30, that is, Mixed Zone is positioned at the lower section of drainage plate 30.In other words
Say, be drained to the gas of cooling chamber 21 and via the gas after cooler 10 heat exchange via the second return air inlet 212
Body flows to blower fan 40 after (upstream of blower fan 40) mixing at drainage plate 30 again, makes solidifying frost condense in drain
At plate 30.
Further, drainage plate 30 can be the plate-shaped member being made up of metal material, to improve drainage plate
30 heat conductivility.Preferably, drainage plate 30 can be made up of the preferable material of the heat conductivilitys such as copper, ferrum.
