Control is entered the air output of refrigerating chamber by evaporator, to realize the control of temperature of refrigerating chamber.
Fig. 1 show a kind of cross-sectional view in side by side combination refrigerator air duct of the prior art.As shown, this side by side combination refrigerator
Freezing chamber a and refrigerating chamber b or so be arranged side by side, further comprising: refrigerated liner 1, blower cover board 2, freezing blower 3, wind
Machine support 4, evaporator 5, central sill foam 6, refrigeration air door 7, refrigeration air duct foam 8, refrigeration air duct cover board 9, foaming box body 10.Its
In, the refrigeration air door 7 is set in refrigerating chamber b.
Fig. 2 show the cross-sectional view of the side by side combination refrigerator of Fig. 1 prior art.As shown, being steamed during refrigerator work
It sends out device 5 to freeze, freezing blower 3 works, and freezing blower 3 send the air after refrigeration by blower cover board 2 and central sill foam 6 respectively
Enter freezing chamber a and refrigerating chamber b.The air-supply entrance of refrigerating chamber b is provided with refrigeration supply air duct, refrigerates supply air duct by refrigeration wind
Door 7, refrigeration air duct foam 8 and refrigeration air duct cover board 9 form.When refrigerating chamber needs to freeze, refrigeration air door 7 is opened, cold air
Enter refrigerating chamber by refrigeration air duct foam 8 and refrigeration air duct cover board 9, freezes to refrigerating chamber；When refrigerating chamber does not need to make
When cold, refrigeration air door 7 is closed, and cold air cannot be introduced into cooling compartment.
(it is lower than 10 since the air themperature for entering refrigerating chamber from evaporator is relatively low in this refrigerator air duct of the prior art
Degree Celsius), in order to avoid there is dew condensation phenomenon in refrigerating chamber air duct, refrigeration supply air duct can it is internal can using polystyrene foam into
Row is heat-insulated, causes the size for refrigerating supply air duct bigger, refrigerator cold-storage chamber interior dischargeable capacity is made to reduce 10L or more, cannot

Specific embodiment
Below with reference to specific embodiment shown in the drawings, the present invention will be described in detail.But these embodiments are simultaneously
The present invention is not limited, structure that those skilled in the art are made according to these embodiments, method or functionally
Transformation is included within the scope of protection of the present invention.
It is to be appreciated that unless otherwise clearly defined and limited, in the description of the present invention, term " center " " is indulged
To ", " transverse direction ", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside" etc.
The orientation or positional relationship of instruction is to be merely for convenience of retouching determined by visual angle for the door body side for facing refrigerator based on user
It states the present invention and simplifies description, rather than the device or element of indication or suggestion meaning must have a particular orientation, with specific
Orientation construction and operation.In addition, term " first ", " second " etc. are used for description purposes only, and it should not be understood as instruction or dark
Show relative importance.
It is in the present specification to implement example, but the invention is not limited to the ice in this room room example with side by side combination refrigerator
Case can also be applied to other kinds of refrigerator.
Please refer to the cross-sectional view in the side by side combination refrigerator air duct that Fig. 3 is an embodiment of the present invention.As shown, this split
The left and right freezing chamber a ' and refrigerating chamber b ' of door refrigerator is arranged side by side, further comprising: refrigerated liner 1 ', fan supporter 2 ', cold
Freeze blower 3 ', evaporator 4 ', refrigeration air supply damper 5 ', air door thermal insulator 6 ', refrigeration liner 7 ', central sill air-supply thermal insulator 8 ', cold
Hide air duct 9 ', foaming box body 10 '.
In order to avoid refrigeration air duct occupies refrigerating chamber dischargeable capacity, present invention eliminates refrigerating chamber is arranged in the prior art
In refrigeration air door, instead, the setting refrigeration air supply damper in freezing chamber, which is integrated in evaporation
Device top can effectively improve the plot ratio of refrigerating chamber in this way, while refrigeration air supply damper sealing for convenience, send in refrigeration
Wind damper positions are additionally provided with air door thermal insulator, and refrigeration air supply damper is fixed on blower by air door thermal insulator and bracket claw
On bracket.In refrigerator assembling, firstly, fan supporter 2 ', freezing blower 3 ', refrigeration air supply damper 5 ', air door thermal insulator 6 '
It is integrally assembled in advance, forms refrigeration air-supply assembly；Then, directly refrigeration air-supply assembly is installed in freezing chamber.
Further, since refrigeration air supply damper is arranged in freezing chamber, air supply damper is refrigerated in order to prevent and is frozen,
Cover board generally is added in refrigeration air supply damper, and heater strip is installed on the cover board.
Further, freeze indoor air-supply passage inner icing in order to prevent, air door thermal insulator need it is certain every
Hot thickness.In one embodiment, air door thermal insulator is polystyrene foam, and thickness is between the range of 15mm to 25mm
It is interior.Most preferably, polystyrene foam is with a thickness of 20mm or so.
Further, if using the other materials except polystyrene foam, for example, other kinds of plastics.Such as adopt
With other materials, correspondingly, the thickness of thermal insulator can change.
Further, refrigeration air door freezes in order to prevent, and heater strip or vacuum are generally provided in plastics thermal insulator
Thermal insulation board.
Further, refrigeration air duct can only extend horizontally and to central sill upper section, and be drawn by less air outlet
To refrigerating chamber.More preferably, refrigeration air duct include the first segment for first extending horizontally and to central sill upper section, then along central sill to
The second segment of lower extension, and it is drawn out to refrigerating chamber by more air outlets, take this refrigerating efficiency for improving cold compartment of refrigerator.
Fig. 6 is air circulation schematic diagram in the process of refrigerastion of an embodiment of the present invention, and the present invention will refrigerate air supply damper
Setting is internal in freezing chamber a ', additionally it is possible to effectively solve refrigeration air duct existing in the prior art Air Leakage.As shown, working as
When refrigerating chamber b ' needs to freeze, freezing blower work, refrigeration air door is opened, and cold air passes through refrigeration air supply damper 5 ' → wind at this time
Door thermal insulator 6 ' → central sill air duct thermal insulator 8 ' → refrigeration air duct 9 ' enters refrigerating chamber；It is cold when refrigerating chamber b ' does not need refrigeration
It hides air door to close, freezing chamber a ' and refrigeration air supply damper 5 ' can be completely cut through, refrigerating chamber b ' is avoided to leak out.
Further, as shown in fig. 6, refrigeration air duct first extends horizontally and to the first segment outer cladding wind of central sill upper section
Door thermal insulator, the second segment outer cladding central sill air duct thermal insulator extended downwardly along central sill take this to alleviate refrigerating chamber close to freezing
The dew condensation phenomenon of room side inner wall.
Compared with prior art, an embodiment of the present invention side by side combination refrigerator has bigger refrigerating chamber low capacity again, and
It is effectively prevented from cooling gas leakage.
