In an embodiment of the present invention, refrigerator includes multiple rooms and compressor.Wherein, the quantity of a room the most specifically limits
Fixed, the quantity of a room is needed to determine by the design of refrigerator.For convenience of the explanation of the control method of refrigerator, in following enforcement
Between all limiting in the description of example and example, the quantity of room is as three, room between respectively first room, second compartment and the 3rd.
Multiple rooms are respectively arranged with air door, and after compressor start, the corresponding air door of each room opens or closes and can control this
Between room whether freeze.It should be noted that other elements of refrigerator such as condenser, evaporimeter and the knot of restricting element
Structure and operation principle etc. have been well known to those of ordinary skill in the art, are the most just not described in detail.
Specifically, refrigerator has general mode and energy saver mode.After refrigerator starts, refrigerator enters general mode, now presses
Contracting machine starts and freezes each room.After the temperature of each room meets certain condition, refrigerator enters energy-conservation mould
Formula.Wherein, the general mode of refrigerator is the refrigeration mode disclosed in prior art, in the ordinary mode compressor and each
The working method of air door is well known to those skilled in the art, the most in the following description by no longer common to refrigerator
Pattern is described in detail.
As depicted in figs. 1 and 2, the control method of the refrigerator of the embodiment of the present invention comprises the following steps:
S1: detect each room temperature T0 and each between operation time of room, and the temperature of each room that will detect
Degree T0 and difference DELTA T2 of the first setting value Tf and the second setting value T1 compare.
In some examples of the present invention, each indoor of refrigerator are equipped with the temperature inspection for detecting corresponding compartment temperature
Survey device and for calculate corresponding between the timer running the time of room, refrigerator in general mode or energy saver mode, temperature
The temperature that detection device is indoor between all detecting accordingly.
Specifically, the temperature being positioned between first first room that indoor temperature-detecting device detects is T0a, between first
First setting value of room is Tfa, and temperature T0a of first room and the difference of the first setting value Tfa are Δ T2a, i.e. Δ
T2a=T0a-Tfa, the second setting value of first room is T1a.It is positioned at what the temperature-detecting device of second compartment detected
The temperature of second compartment is T0b, and the first setting value of second compartment is Tfb, and temperature T0b of second compartment and first sets
The difference of definite value Tfb is Δ T2b, i.e. Δ T2b=T0b-Tfb, and the second setting value of second compartment is T1b.It is positioned at the 3rd
Between the temperature of the 3rd room that detects of indoor temperature-detecting device be T0c, the first setting value of the 3rd room is Tfc,
Temperature T0c of the 3rd room and the difference of the first setting value Tfc are Δ T2c, i.e. Δ T2c=T0c-Tfc, the 3rd room
Second setting value is T1c.Wherein it is desired to explanation, the first setting value Tf of each room and the second setting value T1
Specifically set according to actual conditions, first room, second compartment and the first setting value Tf of the 3rd room can identical also
Can be different, between first room, second compartment and the 3rd, the second setting value T1 of room can be the same or different.
It is to say, temperature-detecting device detects the temperature of room between first room, second compartment and the 3rd in S1 step,
And Δ T2a with T1a, Δ T2b with T1b, Δ T2c with T1c are compared.
S2: when difference DELTA T2 of temperature T0 and the first setting value Tf each room being detected is less than or equal to the second setting value
After T1 and first scheduled time of continuous service Mf, controlling compressor shutdown, now refrigerator enters energy saver mode, energy-conservation
In pattern, temperature T0 according to each the room detected controls compressor start or shutdown；When arbitrary room being detected
When difference DELTA T2 of temperature T0 and the first setting value Tf is more than the second setting value T1, return to step S1.
It is to say, the comparative result obtained by step S1, as judging whether refrigerator possesses the condition of entrance energy saver mode.
If each room meets the condition entering energy saver mode simultaneously, then refrigerator enters energy saver mode.If each room cannot
Meet the condition entering energy saver mode, then refrigerator maintains in the ordinary mode simultaneously.
Specifically, when temperature T0 of arbitrary room and between this difference DELTA T2 of the first setting value Tf of room less than or equal to second
During setting value T1, the timer of this room starts timing.During timing, if temperature T0 of this room and room between this
Difference DELTA T2 of the first setting value Tf maintain the state less than or equal to the second setting value T1, then timer is uninterrupted,
Until refrigerator enters energy saver mode, now between the meter of this room, the time is M0.During timing, if this room
Temperature T0 and between this, difference DELTA T2 of the first setting value Tf of room is more than the second setting value T1, then timer resets, directly
To temperature T0 of this room and between this difference DELTA T2 of the first setting value Tf of room less than or equal to the second setting value T1 time,
The timer of this room restarts timing again.
If the timing time M0 of each room is both greater than the first scheduled time Mf of room, then each room between being equal to accordingly
Meeting the condition entering energy saver mode, now refrigerator enters energy saver mode simultaneously.
Below to further illustrate as a example by room between respectively first, multiple rooms room, second compartment and the 3rd.By step
The comparative result that S1 obtains, as Δ T2a≤T1a, the timer of first room starts timing, the timing of first room
Time is M0a.As Δ T2b≤T1b, the timer of second compartment starts timing, and the timing time of second compartment is
M0b.As Δ T2c≤T1c, the timer of the 3rd room starts timing, and the timing time of the 3rd room is M0c.
Wherein, first scheduled time of first room is Mfa, and first scheduled time of second compartment is Mfb, between the 3rd
First scheduled time of room is Mfc.As M0a >=Mfa and M0b >=Mfb and M0c >=Mfc, then each room is same
Time meet enter energy saver mode condition, now refrigerator enter energy saver mode.
If in during the timing of first room, the temperature rising of first room makes Δ T2a ＞ T1a, then first room
Timer reset, say, that M0a=0.Until during Δ T2a≤T1a, the timer of first room restarts meter
Time.Second compartment is identical with the situation of first room with the situation of the 3rd room, the most just repeats no more.
Further, in energy saver mode, compressor is in stopped status, when the temperature of each room meets cryogenic conditions
Rear compressor just starts, if the temperature of each room can not meet above-mentioned condition, compressor will be shut down again.Thus,
The initiation culture of compressor can reduce, thus extends the service life of compressor, reduces the energy consumption of refrigerator.
S3: in energy saver mode, when difference DELTA T2 of temperature T0 and the first setting value Tf that arbitrary room detected is more than
During the second setting value T1, refrigerator exits energy saver mode, now returns to step S1.
It is to say, in energy saver mode, if difference DELTA T2 of temperature T0 of each room and the first setting value Tf is little
In equal to the second setting value T1, then refrigerator maintains energy saver mode state.If temperature T0 of arbitrary room and first sets
Difference DELTA T2 of definite value Tf is more than the second setting value T1, then refrigerator exits energy saver mode and enters general mode.Until it is each
Between individual, temperature T0 of room and difference DELTA T2 of the first setting value Tf are less than or equal to the second setting value T1, simultaneously each room
Timing time M0 >=Mf, refrigerator just can be again introduced into energy saver mode.
It should be noted that the first setting value Tf of each room, the second setting value T1 and the first equal root of scheduled time Mf
Determine according to the actual demand of refrigerator design, be not especially limited here.
In a concrete example of the present invention, multiple rooms are respectively room between first room, second compartment and the 3rd,
T1a=T1b=T1c=2 degree, Mfa=Mfb=Mfc=3 hour.Now, when Δ T2a≤2 degree and Δ T2b≤2 degree and Δ
T2c≤2 degree, M0a >=3 hour and M0b >=3 hour and M0c >=3 are little constantly simultaneously, and refrigerator enters energy saver mode.
In energy saver mode, when the situation of one of them of Δ T2a ＞ 2 degree, Δ T2b ＞ 2 degree and Δ T2c ＞ 2 degree occurs,
Refrigerator exits energy saver mode.
The control method of refrigerator according to embodiments of the present invention, by being provided with energy saver mode so that the temperature of each room is full
After foot certain condition, compressor just starts, thus reduces the initiation culture of compressor, and then extends the service life of compressor,
And reduce the energy consumption of refrigerator.
In some embodiments of the invention, step S3 also includes step S31 and step S32.
Wherein, step S31: in energy saver mode, when detecting that one of them room sends refrigeration request, control pressure
Contracting machine starts to freeze this room.
It is to say, one of them room or more than one room in multiple rooms are room between setting, compressor only exists
Just starting during the refrigeration request that between accepting to set, room sends, thus, the initiation culture of compressor can reduce.Wherein, set
Between room quantity by refrigerator actual demand determine.
Specifically, one of them room sends refrigeration request is that a temperature T0 room being detected is more than or equal to the first setting value
Tf.Between setting, room illustrates as a example by first room, and as T0a >=Tfa, first room sends refrigeration to compressor
Request, now compressor start, the air door of first room is in open mode, is freezed in first room by compressor.
In an example of the present invention, after compressor start, as T0a ＜ Tfa, the air door of first room is closed, pressure
Contracting machine stops freezing first room, and as T0a >=Tfa, the air door of first room is again turned on, and compressor is again
Secondary is freezed in first room.In another example of the present invention, during compressor start, the air door of first room
Maintain open mode, until the air door of first room is just closed during compressor shutdown.
Further, after compressor start, one of them room in remaining room of multiple rooms sends refrigeration please
When asking, refrigerator controls corresponding air door and opens to freeze this room.Further, when above-mentioned room stop to
When compressor sends refrigeration request, the air door of this room is closed, and now compressor stops freezing this room.
Specifically, remaining room with multiple rooms illustrates as a example by room as second compartment with between the 3rd, as T0b >=Tfb
Time, second compartment sends refrigeration request to compressor, and now the air door of second compartment is opened, and second compartment is entered by compressor
Row refrigeration, as T0b ＜ Tfb, the air door of second compartment is closed.As T0c >=Tfc, the 3rd room is sent out to compressor
Going out refrigeration request, now the air door of the 3rd room is opened, and is freezed in the 3rd room by compressor, as T0c ＜ Tfc,
The air door of the 3rd room is closed.
Step S32: after compressor start when temperature T0 each room being detected is respectively less than three setting values T3,
Compressor shutdown, now returns to step S31.Wherein, the 3rd setting value T3 of each room is by the actual design of refrigerator
Demand determines, is not especially limited here.
Specifically, it is respectively between first room, second compartment and the 3rd as a example by room by multiple rooms of refrigerator, first room
The 3rd setting value be T3a, the 3rd setting value of second compartment is T3b, and the 3rd setting value of the 3rd room is T3c,
As T0a ＜ T3a and T0b ＜ T3b and T0c ＜ T3c, compressor shutdown.
For convenience of describing, in energy saver mode, compressor to the running before rear time startup, is referred to as after previous startup
One kind of refrigeration cycle of energy saver mode.Refrigerator is when actually used, and compressor may run multiple refrigeration in energy saver mode
Circulation, it is also possible to run a kind of refrigeration cycle, it is also possible to refrigerator just exits energy saver mode when being not fully complete a kind of refrigeration cycle.
In some embodiments of the invention, in step S31, after compressor start, when multiple rooms being detected
Remaining room in one of them room send n-th refrigeration request time, air door close, wherein N >=2.Namely
Saying, in a kind of refrigeration cycle of compressor, between non-setting, the air door of room can only be opened once, i.e. compressor sets non-
Between fixed, can only freeze once in room, thus, it is possible to decrease the switching frequency of the air door of this room.
In one particular embodiment of the present invention, as in figure 2 it is shown, one of them of multiple rooms is refrigerator room, cold
Between Tibetan, room is room between setting.In step S31, only detect that when refrigerator room sends refrigeration request, compressor just opens
Dynamic.
In one particular embodiment of the present invention, remaining room of multiple rooms is respectively refrigerating chamber and temperature-changing chamber.
Being described the control method of refrigerator according to the preferred embodiment of the invention below with reference to Fig. 2, wherein refrigerator includes
First to the 3rd room, first room is refrigerator room, and second compartment is refrigerating chamber, and the 3rd room is temperature-changing chamber.
