Firstly the need of explanation, in the entire progress control method, the acquisition freezing in real time of temperature collecting module 62 The temperature Tf of the room 21 and temperature Tr of refrigerating chamber 22, in order to which control system 60 carries out temperature to freezing chamber 21 and refrigerating chamber 22 Regulation.That is, unless otherwise stated, step " the temperature Tr of the temperature Tf of acquisition freezing chamber 21 and refrigerating chamber 22 in real time " Persistently occur and execute in the overall process of the progress control method.

Referring to Fig. 3, after the operational process " beginning " of the progress control method, judge the first preset condition and second in advance If whether at least one of condition meets (step S101).Wherein, first preset condition corresponds to institute for the temperature Tr Refrigeration booting preset temperature section (Tron ,+∞) is stated, judges whether first preset condition meets namely judgment module 64 Judge whether Tr > Tron is true；Second preset condition is set as the temperature Tf corresponding to the default temperature of freezing booting It spends section (Tfon ,+∞), judges whether second preset condition meets namely whether judgment module 64 judges Tf > Tfon It sets up.

In step s101, when (step S101-N) is not satisfied in first preset condition and second preset condition When, continue to execute step S101；Until when at least one of first preset condition and second preset condition meets (step Rapid S101-Y) when, execute step S102.

Judge whether third preset condition and at least one of the 4th preset condition meet (step S102).Wherein, described Third preset condition is that the temperature Tr corresponds to the first preset temperature section (Tron+T2 ,+∞) of the refrigeration, described in judgement Whether third preset condition meets namely judgment module 64 judges whether Tr > Tron+T2 is true；4th preset condition is set The temperature Tf is set to corresponding to the first preset temperature section (Tfon+T1 ,+∞) of the freezing, judges described 4th default article Whether part meets namely judgment module 64 judges whether Tf > Tfon+T1 is true.

In step s 102, when (step S102-N) is not satisfied in the third preset condition and the 4th preset condition When, control module 65 controls refrigerator 100 and executes constant temperature mode (step S200)；Otherwise, when the third preset condition and described When at least one of 4th preset condition meets (step S102-Y), control module 65 controls refrigerator 100 and executes high load mode (step S400).

The refrigerator and its progress control method of the present embodiment are realized by setting freezing air door, refrigeration air door to freezing chamber With the difference temperature control of refrigerating chamber；And after judgement reaches compressor start up condition, then carry out refrigerator whether the judgement of high load, realize refrigerator When high load and the different temperature controls of normal boot-strap (namely constant temperature mode), not only realize that freezer temperature fluctuation is small, but also realize Energy-saving consumption-reducing and temperature is quickly dragged down, avoids the adverse effect of temperature fluctuation or long term high temperature to food storage quality.

Further, in the constant temperature mode (step S200), the control refrigerator 100 of control system 60 alternately enters described Refrigeration state and the freezing refrigerating state, that is to say, that under Yu Suoshu constant temperature mode, to refrigerating chamber 22 and freezing chamber 21 Cooling supply when different.Referring to Fig. 4, which illustrate carrying out practically controlling party of the refrigerator 100 under the constant temperature mode (step S200) Method.

Judgment module 64 judge the temperature Tr whether correspond to the 4th preset temperature section of the refrigeration (- ∞, Troff] (step S201), that is, judging whether Tr≤Troff is true, so that it is determined that whether refrigerating chamber 22 reaches refrigeration shutdown Point, to determine the need for 22 cooling supply of refrigerating chamber.

In step s 201, as Tr≤Troff(step S201-Y) when, control module 65 controls described in the entrance of refrigerator 100 It freezes refrigerating state (step S202), thus only to 21 cooling supply of freezing chamber；As Tr > Troff(step S201-N) when, control mould Block 65 controls refrigerator 100 into the refrigeration state and the synchronous statistics refrigerator 100 of timing module 63 is in refrigeration system The time t(step S203 of cold state).Wherein, whenever refrigerator 100 switches into the refrigeration shape by other operating statuses State, time t is from new timing in step 203, and when refrigerator 100 switches to other operating statuses by the refrigeration state When, the time t is reset.

Since the one of the prerequisite that refrigerator executes the constant temperature mode (step S200) is: Tr > Tron and Tf > Tfon At least one set up, namely at least one of freezing chamber and refrigerating chamber have reached compressor start up condition at this time.And in the constant temperature mould Under formula, by executing step S201, as Tr≤Troff directly to freezing chamber cooling supply without to refrigerating chamber cooling supply, as Tr > First to refrigerating chamber cooling supply when Troff, the influence to freezer temperature is avoided when on the one hand can be achieved in this way to refrigerating chamber cooling supply, separately As long as on the one hand booting refrigerating chamber all can not be preferentially to refrigerating chamber cooling supply, to reduce booting below refrigeration Burnout every time Number and cold consumption.

Further, as Tr > Troff(step S201-N), control module 65 controls refrigerator 100 and enters refrigeration system The synchronous statistics refrigerator 100 of cold state and timing module 63 is in the time t(step S203 of the refrigeration state) when (step S201 is judged as that the control that step S202 is executed when Y will be described later), to the independent cooling supply of refrigerating chamber 22 without to freezing chamber 21 Cooling supply reduces the influence to 21 temperature of freezing chamber.

With continuing for the refrigeration state, the temperature Tr of refrigerating chamber 22 is persistently reduced, and judgment module 64 is sentenced The temperature Tr that breaks whether correspond to the 4th preset temperature section of the refrigeration (- ∞, Troff] (step S207), namely judgement Whether Tr≤Troff is true, so that it is determined that whether refrigerating chamber 22 reaches refrigeration Burnout.

In step S207, as Tr≤Troff (step S207-Y), step S202(is executed likewise, executing step The control of S202 will be described later)；As Tr > Troff(step S207-N) when, whether judgment module 64 judges the time t Reach the first preset time t 1(step S208).Wherein, first preset time t 1 is acquired by setting module 61, in this implementation In example, first preset time t, 1=10min.

In step S208, as t < t1(step S208-N) when, refrigerator 100 continue to keep the refrigeration state with Cooling supply is carried out to refrigerating chamber 22, and judgment module 64 continues to judge whether the temperature Tr corresponds to the default temperature of the refrigeration the 4th Degree section (- ∞, Troff] (step S207)；And as t >=t1(step S208-Y) when namely the refrigeration state continue First preset time t 1, and the still not up to refrigeration Burnout of refrigerating chamber 22, at this point, control module 65 controls refrigerator 100 It executes abnormal patterns (step S300).

In this way, can make when the case where refrigerating chamber is still unable to reach preset temperature through ultra-long time refrigeration occurs in refrigerator, Such as the Men Wei of refrigerating chamber is closed tight, control refrigerator executes abnormal patterns, so that refrigeration system be avoided to cause to damage because of longtime running It is bad, also reduce energy loss.

Certainly, the sequencing of step S207 and step S208 are not limited to the present embodiment.That is, in short, it is described The part step S203-S207-S202-S208-S300 of progress control method is actually: control module 65 controls refrigerator 100 The refrigeration state is kept, until: the temperature during reaching first preset time t 1 in the time t Tr do not correspond to always the 4th preset temperature section of the refrigeration (- ∞, Troff] time control ice making box 100 executes the abnormal mould Formula, or, having corresponded to the refrigeration the 4th in advance when reaching 1 foregoing description temperature Tr of the first preset time t in the time t If temperature range (- ∞, Troff] entrance of the time control ice making box 100 freezing refrigerating state.

Further, in the present embodiment, as Tr≤Troff(step S201-Y or step S207-Y) when, control module 65 control refrigerators 100 enter the freezing refrigerating state (step S202), continue at this time with the freezing refrigerating state, cold The temperature Tf for freezing room 21 is persistently reduced；It is default that judgment module 64 judges whether the temperature Tf corresponds to the freezing the 4th Temperature range (- ∞, Tfoff] (step S204), namely judge whether Tf≤Tfoff true, so that it is determined that freezing chamber 21 whether Reach freezing Burnout.

In step S204, if Tf≤Tfoff invalid (step S204-N), judgment module 64 judges the temperature Tr Whether correspond to refrigeration booting preset temperature section (Tron ,+∞) (step S206), namely whether judges refrigerating chamber 22 Refrigeration starting point is reached.In step S206, if Tr≤Tron(step S206-N), return step S204；If Tr > Tron(step S206-Y), it thens follow the steps S203 namely control module 65 controls refrigerator 100 and reenters the refrigeration State and 63 re-synchronization of timing module statistics refrigerator 100 are in the time t(step S203 of the refrigeration state).

In step S204, if Tf≤Tfoff sets up (step S204-Y), control module 65 controls refrigerator 100 and enters The shutdown status (step S205), to terminate this operational process.

The refrigerator and its progress control method of the present embodiment, the temperature Tr of refrigerating chamber meet (Troff, Tron] it is preferential Power be higher than freezing chamber temperature Tf meet (Tfoff, Tfon] priority, not only realize refrigeration chamber when freezer temperature Fluctuate it is small, and make temperature of refrigerating chamber maintain it is constant, avoid as refrigerating chamber switch gate number it is more caused by the easy wave of temperature Dynamic phenomenon improves the storage environment of refrigerating chamber；In addition, also can avoid persistently opening caused by because of refrigerating chamber ultra-long time refrigeration Machine reduces refrigerator damage probability, energy-saving consumption-reducing.

Further, as described above, after the refrigeration state maintains the first preset time t 1 refrigerating chamber 22 still not up to refrigeration Burnout when, control module 65 control refrigerator 100 execute the abnormal patterns (step S300), referring to figure 5, the present embodiment illustrates carrying out practically control method of the refrigerator 100 under the abnormal patterns (step S300).

Specifically, control module 65 controls refrigerator 100 and enters the synchronous refrigerating state (step S301), namely to freezing Room 21 and refrigerating chamber 22 while cooling supply.In the abnormal patterns, judgment module 64 no longer judges corresponding to the temperature Tr Temperature range, and only judge the temperature Tf whether correspond to the 4th preset temperature section of the freezing (- ∞, Tfoff] (step S302).

In step s 302, if Tf > Tfoff(step S302-N), refrigerator 100 maintain the synchronous refrigerating state and Step S302 is continued to execute, until Tf≤Tfoff(step S302-Y) when, control module 65 controls stops described in the entrance of refrigerator 100 Machine state (step S303), to terminate this operational process.

Further, in the high load mode (step S400), the controllable ice making box 100 of control system 60 is in described Synchronous refrigerating state, that is to say, that, can be to refrigerating chamber 22 and freezing chamber 21 while cooling supply under Yu Suoshu high load mode.Referring to Fig. 6, in the present embodiment, different based on the judging result in step S102-Y, the high load mode includes three different Subpattern, below to the high load mode when progress control method be introduced.

Specifically, in step s 102, if the third preset condition meets, the 4th preset condition is unsatisfactory for, That is, Tr > Tron+T2 and Tf≤Tfon+T1,22 high load of refrigerating chamber and the non-high load of freezing chamber 21 at this time, then control module 65 Control refrigerator 100 executes the first subpattern (step S500) of the high load mode.

If the third preset condition is unsatisfactory for and the 4th preset condition meets, that is, Tr≤Tron+T2 and Tf > Tfon+T1, the non-high load of refrigerating chamber 22 and 21 high load of freezing chamber at this time, then control module 65 control refrigerator 100 execute it is described Second subpattern (step S600) of high load mode.

If third preset condition and the 4th preset condition are all satisfied, that is, Tr > Tron+T2 and Tf > Tfon+T1, at this time Refrigerating chamber 22 and the equal high load of freezing chamber 21, then control module 65 controls third that refrigerator 100 executes the high load mode Mode (step S700).

The refrigerator and its progress control method of the present embodiment carry out not when refrigerating chamber, freezing chamber are respectively at high load Same control reduces the influence to freezer temperature, the high-temperature gas because of refrigerating chamber is avoided to draw high when realizing refrigerating chamber high load The temperature of freezing chamber and cause the refrigeration system available machine time extend, energy-saving consumption-reducing；And when freezing chamber high load, it can be achieved that temperature Quickly drag down, avoid hot environment too long to storage food quality adverse effect.

It below will be respectively in connection with Fig. 7, Fig. 8, Fig. 9 to first subpattern (step S500), second subpattern (step Rapid S600), the progress control method of the third subpattern (step S700) described.

Specifically, in step s 102, as Tr > Tron+T2 and Tf≤Tfon+T1, control module 65 controls refrigerator 100 execute first subpattern, and referring to Fig. 7, which illustrate the controls of the carrying out practically of the first subpattern of the embodiment of the present invention Method.

Control module 65 controls refrigerator 100 and enters the refrigeration state (step S501), at this time with the refrigeration Refrigerating state continues, and the temperature Tr of refrigerating chamber 22 is persistently reduced, and can realize quickly drag down refrigerating chamber 22 in this process Temperature Tr, and the high-temperature gas of refrigerating chamber 22 will not have an impact freezing chamber 21.

Judgment module 64 judge the temperature Tr whether correspond to the 4th preset temperature section of the refrigeration (- ∞, Troff] (step S502), namely judge whether Tr≤Troff is true, so that it is determined that whether refrigerating chamber 22 reaches refrigeration shutdown Point.

In step S502, if Tr≤Troff(step S502-Y), control module 65 controls described in the entrance of refrigerator 100 Shutdown status (step S503), to terminate this operational process；If Tr > Troff(step S502-N), judgment module 64 judge whether the temperature Tf corresponds to freezing booting preset temperature section (Tfon ,+∞) (step S504).In this way, The temperature recovery situation that freezing chamber can be monitored in real time before refrigerating chamber reaches refrigeration Burnout, avoids blindly only holding refrigerating chamber It is shut down after continuous cooling supply and freezer temperature gos up the case where being repeatedly switched in this process.

In step S504, if Tf≤Tfon(step S504-N), refrigerator 100 continues to keep the refrigeration state And judgment module 64 continue to judge the temperature Tr whether correspond to the 4th preset temperature section of the refrigeration (- ∞, Troff] (step S502)；Otherwise, if Tf > Tfon(step S504-Y) namely freezing chamber 21 reach freezing starting point, and refrigerate at this time Refrigeration Burnout has not yet been reached in room 22, and control module 65 controls refrigerator 100 and enters the synchronous refrigerating state (step S505), with To refrigerating chamber 22 and freezing chamber 21 while cooling supply.

With continuing for the synchronous refrigerating state, the temperature Tr of refrigerating chamber 22 and the temperature Tf of freezing chamber 21 Lasting to reduce, in this process, judgment module 64 judges whether the temperature Tf corresponds to the 4th preset temperature of the freezing Section (- ∞, Tfoff] (step S506).

In step S506, if Tf≤Tfoff(step S506-Y), return step S501；Otherwise (step S506-N), Then judgment module 64 continues to execute step S506.

The refrigerator and its progress control method of the present embodiment, it is first right in refrigerating chamber high load and when the non-high load of freezing chamber While refrigerating chamber cooling supply is quickly to drag down temperature of refrigerating chamber, influence of the refrigerating chamber high-temperature gas to the temperature of freezing chamber is avoided, The temperature recovery situation of freezing chamber is monitored, enters synchronous refrigerating state in due course, avoids multiplicating from being switched on, energy saving.

Further, in step s 102, as Tr≤Tron+T2 and Tf > Tfon+T1, control module 65 controls refrigerator 100 enter second subpattern (step S600), and referring to Fig. 8, which illustrate the tools of the second subpattern of the embodiment of the present invention Running body control method.

Control module 65 controls refrigerator 100 and enters the freezing refrigerating state (step S601), at this time with the freezing Refrigerating state continues, and the temperature Tf of freezing chamber 21 is persistently reduced, and only effectively limits 21 cooling supply of freezing chamber in this process Having contracted need to be by the spatial volume of cooling supply, it can be achieved that quickly dragging down the temperature Tf of freezing chamber 21.

Judgment module 64 judge the temperature Tf whether correspond to the 4th preset temperature section of the freezing (- ∞, Tfoff] (step S602), namely judge whether Tf≤Tfoff is true, so that it is determined that whether freezing chamber 21 reaches freezing shutdown Point.

In step S602, if Tf≤Tfoff(step S602-Y), control module 65 controls described in the entrance of refrigerator 100 Shutdown status (step S603), to terminate this operational process；If Tf > Tfoff(step S602-N), judgment module 64 judge whether the temperature Tr corresponds to refrigeration booting preset temperature section (Tron ,+∞) (step S604).In this way, The temperature recovery situation that refrigerating chamber can be monitored in real time before freezing chamber reaches freezing Burnout, avoids blindly only holding freezing chamber It is shut down after continuous cooling supply and temperature of refrigerating chamber gos up the case where being repeatedly switched in this process.

In step s 604, if Tr≤Tron(step S604-N), refrigerator 100 continues to keep the freezing refrigeration shape State, and judgment module 64 continue to judge the temperature Tf whether correspond to the 4th preset temperature section of the freezing (- ∞, Tfoff] (step S602)；Otherwise, if Tr > Tron(step S604-Y) namely refrigerating chamber 22 reach refrigeration starting point, and this When freezing chamber 21 have not yet been reached freezing Burnout, control module 65 controls refrigerator 100 and enters the synchronous refrigerating state (step S605), with to refrigerating chamber 22 and freezing chamber 21 cooling supply simultaneously.

With continuing for the synchronous refrigerating state, the temperature Tr of refrigerating chamber 22 and the temperature Tf of freezing chamber 21 Lasting to reduce, in this process, judgment module 64 judges whether the temperature Tr corresponds to the 4th preset temperature of the refrigeration Section (- ∞, Troff] (step S606).

In step S606, if Tr≤Troff(step S606-Y), return step S601；Otherwise (step S606-N), Then judgment module 64 continues to execute step S606.

The refrigerator and its progress control method of the present embodiment, in freezing chamber high load when the non-high load of refrigerating chamber, first only To freezing chamber cooling supply, quickly to drag down freezer temperature, avoid causing freezing chamber rate of temperature fall slack-off refrigerating chamber cooling supply simultaneously, To reduce food resting period in the high temperature environment；Meanwhile the temperature recovery situation of refrigerating chamber is monitored, enter synchronous refrigeration in due course State avoids that booting, energy saving is repeated several times.

Further, in step s 102, as Tr > Tron+T2 and Tf > Tfon+T1, control module 65 controls refrigerator 100 enter the third subpattern (step S700), and referring to Fig. 9, which illustrate the tools of the embodiment of the present invention third subpattern Running body control method.

Control module 65 controls refrigerator 100 and enters the synchronous refrigerating state (step S701), to freezing chamber 21 and refrigeration Room 22 while cooling supply, to realize to 22 fast cooling of freezing chamber 21 and refrigerating chamber.

With continuing for the synchronous refrigerating state, judgment module 64 successively successively judges whether the temperature Tf corresponds to The 4th preset temperature section of the freezing (- ∞, Tfoff] whether (step S702), the temperature Tr correspond to the refrigeration the Four preset temperature sections (- ∞, Troff] (step S7031, step S7032).

Wherein, as Tf > Tfoff(step S702-N) and Tr > Troff(step S7032-N) when, refrigerator 100 is after continuation of insurance The synchronous refrigerating state is held, and judgment module 64 continues temperature range corresponding to the temperature Tf, the temperature Tr Judgement；As Tf > Tfoff(step S702-N) and Tr≤Troff(step S7032-Y) when, control module 65 controls refrigerator 100 enter the freezing refrigerating state (step S704)；As Tf≤Tfoff(step S702-Y) and Tr≤Troff(step When S7031-Y), control module 65 controls refrigerator 100 and enters the shutdown status (step S706), to terminate this operation Process；As Tf≤Tfoff(step S702-Y) and Tr > Troff(step S7031-N) when, control module 65 controls refrigerator 100 Only to 22 cooling supply of refrigerating chamber (control in this case will be described later).

Firstly, specifically, as Tf > Tfoff(step S702-N) and Tr≤Troff(step S7032-Y) when, it is cold at this time Freezing Burnout has not yet been reached in jelly room 21 and refrigerating chamber 22 has reached refrigeration Burnout, and control module 65 controls refrigerator 100 and enters The freezing refrigerating state (step S704), only to 21 cooling supply of freezing chamber.

With continuing for the freezing refrigerating state, the temperature Tf of freezing chamber 21 is persistently reduced, and judgment module 64 is sentenced The temperature Tf that breaks whether correspond to the 4th preset temperature section of the freezing (- ∞, Tfoff] (step S705).(step if not Rapid S705-N), then refrigerator 100 keeps the freezing refrigerating state, and judgment module 64 continues to execute step S705, until Tf≤ Tfoff(step S705-Y) when control module 65 control refrigerator 100 and enter the shutdown status (step S706), to terminate this Secondary operational process.
