Minute.
Embodiment two
As preferred embodiment, in the control method of above-mentioned refrigerator air door, refrigerator has an evaporator, refrigerator
In each compartment, the compartment provided with evaporator is compartment 1, the air door of compartment 1 include the air-supply air door 1a of compartment one and
The return air air door 1b of room one, the air door of remaining compartment has only included the air door in air-supply air door, above-mentioned control method to compartment 1
Control refers to the Synchronization Control to the air-supply of the compartment one air door 1a and return air air door 1b of compartment one.
Described below is done to this method implementation process by taking the refrigerator with two compartments as an example below：
Referring to Fig. 1, refrigerator has one evaporator 3 of two compartments and tool, and the compartment provided with evaporator 3 is compartment 1, separately
One compartment is compartment 22, and the air door of compartment 1 includes the air-supply air door 1a and return air air door 1b of compartment one of compartment one, compartment
22 air door has only included the air-supply air door of compartment two 2a.The refrigeration of compartment 1 passes through the air door 1a and compartment one of being blown to compartment one
Return air air door 1b synchronizes control, and the refrigeration of compartment 22 is controlled by the air-supply air door of compartment two 2a.The control of the refrigerator air door
Method comprises the following steps：
Step A：The actual temperature of compartment 1 and compartment 22 is gathered, the actual temperature value of two compartments is obtained, is designated as
T1 compartment, T2 compartments；
Step B：Set the target temperature value T of two compartments1 target, T2 targets, and pass through formula Δ Ti=TI compartments–TI targets, obtain
To the temperature gap Δ T of two compartmentsi, i.e. Δ T1=T1 compartment–T1 target, Δ T2=T2 compartments–T2 targets, wherein, T1 targetIt is pre- for compartment 1
If door opening temperature or air door closing temperature, T2 targetsFor the default door opening temperature of compartment 22 or air door closing temperature；
Step C：Set the first reference value N and the second reference value M, wherein N<M, and 0<N≤5,5<M≤30, and by as follows
Three conditions control the air door of two compartments：
As Δ T1With Δ T2During respectively less than or equal to N, then the air door Close All of two compartments, while compressor shutdown,
It is every the span for after the time period t of setting, returning again to step A, t：0.1 minute≤t≤5 minute；
As Δ T1With Δ T2It is all higher than or during equal to M, then compressor start work, while the air door of two compartments is opened,
After the time period t for being spaced setting, step A is returned again to；
Under other conditions, then compare two temperature gap Δ T1With Δ T2Size, open maximum temperature difference corresponding to
The air door of compartment, closes the air door of remaining compartment, after the time period t for being spaced setting, returns again to step A.
Δ T is drawn if for example comparing1More than Δ T2, then the air-supply of compartment two air door 2a close, the air-supply air door 1a of compartment one and
The return air air door 1b of room one is opened；Otherwise, the air-supply air door of compartment two 2a is opened, the air-supply air door 1a of compartment one and the return air air door of compartment one
1b is closed.It is in the present embodiment using the beneficial effect of this control rule：The target temperature value T set when compartment 222 targetsCompared with
When low, to meet the target temperature value T that each several part temperature of compartment 22 particularly bottle frame temperature reaches setting as early as possible2 targets, between closing
The air-supply of the compartment one air door 1a and return air air door 1b of compartment one of room 1, it is ensured that have between bigger blast and air quantity be delivered to
Room 22, so as to ensure that compartment 22 faster reaches the target temperature value T of its setting2 targets。
Step D：The door opening of two compartments of record or the duration t of closed mode1 continues, t2 continue, and by the duration
t1 continues, t2 continueRespectively with default duration tIfMake comparisons：
If t1 continues, t2 continueIn have more than or equal to default duration tIfThen correspond to compartment air door action once, wind
Door action once refers to：If air door was opening originally, the action reopened again after the closing for performing main air intake；If
Air door was closed mode originally, then the action being re-closing off again after the unlatching for performing main air intake.Wherein, tIfSpan
For：30 minutes≤tIf≤ 120 minutes.
The control method of a kind of refrigerator air door disclosed by the invention, it is possible to achieve each compartment is rapidly achieved default target
The purpose of temperature, while ensureing refrigeration system Effec-tive Function.For many air door refrigerators, user can be met suddenly in a certain compartment
