As shown in Figures 1 to 8, the invention discloses a kind of refrigerators, specifically, the refrigerator is wind cooling refrigerator.The ice
Case includes shell, liner and at least one receiving compartment being set in liner.In the present embodiment, the receiving compartment packet
Include the first compartment (not shown), second compartment (not shown), third compartment 30, wherein third compartment 30 is optionally with first
Compartment or second compartment are connected.
The refrigerator includes temperature-controlling system, specifically, the temperature-controlling system includes controller (not shown) and successively
Connection forms compressor 4, First Heat Exchanger 1, restricting element, the second heat exchanger 2, the controller and the compressor of closed loop
4 are electrically connected to control the start and stop of compressor 4.In the present invention, the compressor 4 is to allow refrigerant towards the positive direction or reverse flow
Dynamic bi-directional compression machine 4 or the Uniaxial Compression machine 4 for only allowing refrigerant to flow in one direction.When the compressor 4 is unidirectional
When compressor 4, the temperature-controlling system further includes having the control valve being connected with the Uniaxial Compression machine 4 to change the stream of refrigerant
To.In the present invention, the control valve is four-way valve 53, and the four-way valve 53 is connected with the both ends of the Uniaxial Compression machine 4.
Also, the four-way valve 53 is also connected with the controller, to which controller can control four-way valve 53 and Uniaxial Compression machine 4
Connection is to change the flow direction of refrigerant.
To may make refrigerator of the present invention by bi-directional compression machine 4 or Uniaxial Compression machine 4 and the Combination Design of four-way valve 53
Under the control of the controller so that the refrigerant that the high temperature and pressure is compressed by compressor 4 first flows to First Heat Exchanger 1 or first
The second heat exchanger 2 is flowed to, i.e., selective makes First Heat Exchanger 1 and the second heat exchanger 2 realize refrigeration or heat exchange.
In addition, in the present invention, due to refrigerant can two-way flow, the restricting element in the present invention is also designed to
Can two-way flow restricting element.Specifically, the restricting element includes two parallel connections and the first check valve in the opposite direction
51 and second check valve 52, or an only two-way valve 54, so as to meet the needs of refrigerant two-way flow, and also may be used
Equally have the function that decompression.
For the First Heat Exchanger 1 close to first compartment, the second heat exchanger 2 is and in office close to the second compartment
In the case of what, the third compartment 30 has and is only connected with an at most compartment.Specifically, working as the refrigerant forward flow
When (in the accompanying drawings with indicate counterclockwise), the refrigeration of First Heat Exchanger 1, the heating of the second heat exchanger 2, the first compartment refrigeration, the

Indicate clockwise) when, the heating of the First Heat Exchanger 1, the second heat exchanger 2 refrigeration, the first compartment heating, second compartment system
It is cold, and third compartment 30 is at most only connected with the compartment of refrigeration.
Thus, by the forward direction of refrigerant, reverse flow, to same heat exchanger whithin a period of time can heat and
Can refrigeration, even if to heat exchanger surface frosting in process of refrigerastion, during heating again can defrost naturally,
It solves the problems, such as refrigerator defrost, and the energy of refrigerator can be effectively utilized.Also, the refrigerator in the present invention begins
There are the compartment of refrigeration and heating, the compartment of refrigeration to can be used for placing the article for needing to refrigerate or freeze, the compartment of heating eventually
It can be used for placing the article etc. for needing to thaw.
In addition, the time span of the refrigerant forward flow and reverse flow is consistent, i.e., same chamber is freezing
It is identical with the time of heating, so as to preferably reach the transfer of energy, and make defrost more complete.
Also, the third compartment 30 is optionally connected to the first compartment, second compartment and can also not be connected to, specifically
, third compartment 30 is at most only connected to the compartment in refrigerating state, to which the cold of third compartment 30 comes from system
The compartment of cold state, and can be adjusted according to the temperature of its inner air to select not to be connected to any compartment.
The refrigerator includes two wind for being respectively communicated with the first compartment and third compartment, second compartment and third compartment
Road, and the first air door (not shown), the second air door (not shown) of two wind path break-makes are controlled respectively.When the first compartment freezes
When, the second air door is closed, the selectable opening and closing of the first air door；When second compartment is freezed, the first air door is closed, and the second air door can
The opening and closing of selection.
The sensor being electrically connected with the controller is provided in the third compartment 30.When the sensor senses
When the temperature is excessively high, then controller selects the compartment that is freezing to third compartment 30, and by the wind on the wind path being connected to the compartment
Door is opened；When sensor sense 30 temperature of third compartment it is too low when, then controller closes the air door.Also, in order to ensure
The temperature of three compartments 30 is not influenced by the heat exchanger heated, and the third compartment 30 is far between the first compartment, second
Room is arranged, and is provided with thermal insulation layer.
It should be noted that in the present invention, the words such as positive, reversed only only for show flow direction on the contrary, not as
The reference specifically flowed to；Identical, the first, second equal words are only only for narration is facilitated, not as quantity, the ginseng of sequence
It examines, certainly, in the present invention, if further including having third, 4th etc. heat exchanger or compartment etc., also can reach the mesh of the present invention
