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
's.
So that a kind of control method of refrigerator provided by the invention, the control method include:
