Portion is provided with return air inlet 5, for sending the air circulation of storage room 10 back to air duct 20.
The refrigerator of the present embodiment, can be by evaporator 2 under the action of blower 3 operates by the setting of multiple air outlets 4
The cold air at place is sent to storage compartment 10, and the indoor gas in the storeroom that circulates, while being made in storeroom room by return air inlet 5
The gas of circulation is flow at evaporator.Further, since controllable air door is provided at the air outlet of part, therefore, when storage compartment
Temperature reaches preset temperature value, and when storage compartment is in the state that do not freeze, the indoor hot gas in storeroom can rise, cold air can under
It is heavy, at this point, closing controllable air door, it may make the indoor gas in storeroom to circulate under the operating of blower, to store on compartment
The hot gas in portion can be driven to the lower part of storage compartment, and reduce the temperature difference of top and lower part in storeroom room, most
The whole indoor temperature in storeroom basically reaches uniformly.In this way, the refrigerator of the present embodiment can solve storeroom in the prior art
Room is due to the problem of upper part temperature is higher, the temperature of lower lower chamber interior non-uniform temperature so as to cause storeroom.
In a further embodiment, blower 3 may be disposed at the one of air outlet of face.In reality further
It applies in example, blower 3 may be disposed at the air outlet on 10 top of storage room.As shown in Figure 1, blower 3, which is set to, is located at storing
At the air outlet of 10 topmost of compartment.
Wherein, the operating when temperature that blower 3 may be configured in storage room 10 is not up to preset temperature value, for storing up
Circulating current is formed between object compartment and air duct, the cold air at evaporator 2 is sent to storage room, and is circulated in storage room
Gas；Or the temperature in storage room controllably operates when reaching preset temperature value, it can also be in storage room and air duct
Between form circulating current so that be located at storage room in higher position at high-temperature gas be recycled to it is lower in storage room
At position.
In further above-described embodiment, it is equipped at the air outlet of 10 middle part of storage room and/or lower part controllable
Air door 6, so that controllable temperature of the air door 6 in storage room is closed after being reduced to preset temperature value, using in storage room
The air outlet and return air inlet 5 in portion generate airflow circulating under the operating of blower, to reduce storage room top and lower part
The temperature difference.Controllable air door 6 may be configured to unlatching when the temperature in storage room 10 is not up to preset temperature value, so that blower operates
The gas of drive can be flow in storage room 10 by each air outlet.
In above-mentioned further embodiment, multiple air outlets 4 can be two, and (there are two air outlets for refrigerator tool in Fig. 1
Embodiment), from top to bottom respectively first air-supply air port and second air-supply air port, blower 3, which is set to, is right against the first air-supply wind
The position of mouth；Controllable air door 6 is equipped at second air-supply air port.
Alternatively, multiple air outlets can be three, from top to bottom respectively first air-supply air port, second air-supply air port and
Third air-supply air port, blower are set at the position for being right against the first air-supply air port or the second air-supply air port, the second air-supply air port
Or the controllable air door is equipped at third air-supply air port.The quantity of air outlet may be 4,5,6 etc., can be according to reality
Situation is arranged.In this way, the refrigerator of the utility model can accelerate the cold air for issuing evaporator by the way that multiple air outlets are arranged
It send to refrigerating chamber, so as to further increase the efficiency of refrigeration cycle.
It, can be with as shown in Fig. 2, the refrigerator of the present embodiment may also include controller 62 in any of the above-described embodiment
Wind controllable gate 6 communicates to connect, so as to control the unlatching of controllable air door 6 by controller 62.The refrigerator of the present embodiment may be used also
Including temperature sensor 61, it is connected with the communication of controller 62, for acquiring the temperature of storage room 10, so that 62 basis of controller
The temperature that temperature sensor 61 acquires controls the unlatching of controllable air door 6.
In a specific embodiment, the refrigerant in process of refrigerastion can flow through evaporator, by the gas at evaporator
It is cooling, circulating cold air is then driven by the rotation of blower 3, to send cold air to storage compartment 10 by multiple air outlets 4
It is interior.Multiple air outlets 4 can be sequentially arranged from top to bottom at the cover board of storage compartment 10 according to the vertical height of refrigerator.It is in figure
The embodiment of two air outlets, wherein being provided with controllable air door 6, at the relatively low air outlet in position to control by controller
The opening and closing of the controllable air door 6.It is specifically as follows, in normal refrigeration, blower 3 is operated, while controller control
Electronic controllable air door (controllable air door 6) unlatching is made, shown in direction line A and B as shown in figure 1, the cold wind at evaporator 2 passes through two
Air outlet 4, which is flow in storage compartment 10, to freeze, and then loops at evaporator 2, shown in direction line C as shown in figure 1；Work as storage
When the temperature of hiding compartment reaches preset temperature value, refrigerant stops entering evaporator, and blower 3 is closed, that is, storage compartment is in not
The state of refrigeration.At this point, forcing to operate blower 3, controllable air door 6 is simultaneously closed off, at this point, the operating due to blower 3 will store
Between the higher gas of temperature at indoor upper position be recycled at the position of its underpart, then recycled and steamed again by return air inlet 5
It sends out at device 2, evaporator 2 cools down the gas of the higher temperature, then is flow in storeroom room by blower 3 and air outlet 4.
It loops back and forth like this, the gas temperature of the final upper and lower part for realizing storage compartment is almost the same, so that storeroom is indoor
Temperature can be uniform.In this way, solve storage compartment in the prior art due to upper part temperature is higher, temperature of lower it is lower from
And the problem of leading to storeroom chamber interior non-uniform temperature.
So far, although those skilled in the art will appreciate that the more of the utility model have been shown and described in detail herein
A exemplary embodiment still, still can be according to the utility model public affairs in the case where not departing from the spirit and scope of the utility model
The content opened directly determines or derives many other variations or modifications for meeting the utility model principle.Therefore, this is practical new
The range of type is understood that and regards as to cover all such other variations or modifications.
