Firstly the need of explanation, in the whole progress control method, the freezing of the Real-time Collection of temperature collect module 62 Temperature Tf of room 21 and temperature Tr of cold room 22, trip temperature is entered in order to control system 60 to refrigerating chamber 21 and cold room 22 Regulation and control.That is, unless otherwise indicated, step " temperature Tf of Real-time Collection refrigerating chamber 21 and temperature Tr of cold room 22 " Persistently occur in the overall process of the progress control method and perform.

Referring to Fig. 3, after the running " beginning " of the progress control method, judge that first is pre-conditioned and second pre- If whether at least one of condition meets（Step S101）.Wherein, described first it is pre-conditioned be temperature Tr correspond to institute Cold preservation start preset temperature interval (Tron ,+∞) is stated, judges whether described first pre-conditioned meet namely judge module 64 Judge whether Tr ＞ Tron set up；Described second pre-conditioned is set to temperature Tf corresponding to the default temperature of the freezing start Degree interval (Tfon ,+∞), judges whether described second pre-conditioned meet namely whether judge module 64 judges Tf ＞ Tfon Set up.

In step S101, when described first pre-conditioned and described second pre-conditioned be unsatisfactory for（Step S101-N） When, continue executing with step S101；Until when the described first pre-conditioned and described second pre-conditioned at least one meets（Step Rapid S101-Y）When, execution step S102.

Judge that the 3rd is pre-conditioned and whether the 4th pre-conditioned at least one meets（Step S102）.Wherein, it is described 3rd it is pre-conditioned be temperature Tr corresponding to the preset temperature of the cold preservation first interval (Tron+T2 ,+∞), judge described Whether the 3rd pre-conditioned meet namely judge module 64 judges whether Tr ＞ Tron+T2 set up；Described 4th pre-conditioned sets Temperature Tf is set to corresponding to the freezing the first preset temperature interval (Tfon+T1 ,+∞), the described 4th default article is judged Whether part meets namely judge module 64 judges whether Tf ＞ Tfon+T1 set up.

In step s 102, when the described 3rd is pre-conditioned and the described 4th pre-conditioned is unsatisfactory for（Step S102-N） When, the control refrigerator 100 of control module 65 performs constant temperature mode（Step S200）；Otherwise, when the described 3rd is pre-conditioned and described 4th pre-conditioned at least one meets（Step S102-Y）When, the control refrigerator 100 of control module 65 performs high capacity pattern （Step S400）.

The refrigerator and its progress control method of the present embodiment, by arranging freezing air door, cold preservation air door, realizes to refrigerating chamber With the difference temperature control of cold room；And after judging to reach compressor start up condition, then the refrigerator whether judgement of high capacity is carried out, realize refrigerator During high capacity and normal boot-strap（Namely constant temperature mode）Different temperature controls, not only realize freezer temperature fluctuation it is little, and realize Energy-saving consumption-reducing and quickly drag down temperature, it is to avoid temperature fluctuation or long term high temperature store the harmful effect of quality to food.

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

Judge module 64 judge temperature Tr whether corresponding to the preset temperature of the cold preservation the 4th it is interval (- ∞, Troff]（Step S201）, that is, judge whether Tr≤Troff sets up, so that it is determined that whether cold room 22 reaches cold preservation shutdown Point, to determine the need for the cooling of cold room 22.

In step s 201, as Tr≤Troff（Step S201-Y）When, the control refrigerator 100 of control module 65 enters described Freezing refrigerating state（Step S202）, so as to only to the cooling of refrigerating chamber 21；As Tr ＞ Troff（Step S201-N）When, control mould The control refrigerator 100 of block 65 enters the refrigeration state and the synchronous statistics refrigerator 100 of timing module 63 is in the cold preservation system The time t of cold state（Step S203）.Wherein, whenever refrigerator 100 switches into the refrigeration shape by other running statuses Time t is from new timing in state, step 203, and works as refrigerator 100 and switch to other running statuses by the refrigeration state When, the time t resets.

Because refrigerator performs the constant temperature mode（Step S200）One of prerequisite be：Tr ＞ Tron and Tf ＞ Tfon At least one set up, namely now at least one of refrigerating chamber and cold room has reached compressor start up condition.And in the constant temperature mould Under formula, by execution step S201, as Tr≤Troff directly to refrigerating chamber cooling not to cold room cooling, as Tr ＞ First the impact to freezer temperature is avoided when being so on the one hand capable of achieving to cold room cooling, separately to cold room cooling during Troff As long as on the one hand every time start cold room all can not preferentially to cold room cooling, so as to reduce start below cold preservation Burnout Number of times and cold consumption.

Further, as Tr ＞ Troff（Step S201-N）, the control refrigerator 100 of control module 65 is into the cold preservation system The time t of cold state and the synchronous statistics refrigerator 100 of timing module 63 in the refrigeration state（Step S203）When（Step The control of execution step S202 when S201 is judged as Y will be described later）, to the independent cooling of cold room 22 not to refrigerating chamber 21 Cooling, reduces the impact to the temperature of refrigerating chamber 21.

With continuing for the refrigeration state, temperature Tr of cold room 22 is persistently reduced, and judge module 64 is sentenced Temperature Tr of breaking whether corresponding to the preset temperature of the cold preservation the 4th it is interval (- ∞, Troff]（Step S207）, namely judge Whether Tr≤Troff sets up, so that it is determined that whether cold room 22 reaches cold preservation Burnout.

In step S207, as Tr≤Troff（Step S207-Y）When, execution step S202（Likewise, execution step The control of S202 will be described later）；As Tr ＞ Troff（Step S207-N）When, whether judge module 64 judges the time t Reach the first preset time t 1（Step S208）.Wherein, first preset time t 1 is gathered by setting module 61, in this enforcement 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 is carried out to cold room 22, and whether judge module 64 continues to judge temperature Tr corresponding to the default temperature of the cold preservation the 4th Degree interval (- ∞, Troff]（Step S207）；And work as t >=t1（Step S208-Y）When, namely the refrigeration state continue First preset time t 1, and cold room 22 is still not up to cold preservation Burnout, now, the control refrigerator 100 of control module 65 Perform abnormal patterns（Step S300）.

So, can make once refrigerator occur cold room Jing ultra-long times refrigeration be still unable to reach the situation of preset temperature when, The Men Wei of such as cold room is closed tight, and control refrigerator performs abnormal patterns, so as to avoid refrigeration system from causing to damage because of longtime running It is bad, also reduce energy loss.

Certainly, the sequencing of step S207 and step S208 is not limited to the present embodiment.That is, in short, it is described The step of progress control method S203-S207-S202-S208-S300 parts are actually：Control module 65 controls refrigerator 100 The refrigeration state is kept, until：The temperature during first preset time t 1 is reached in the time t Tr do not correspond to all the time the preset temperature of the cold preservation the 4th it is interval (- ∞, Troff] time control ice making case 100 performs the abnormal mould Formula, or, pre- corresponding to the cold preservation the 4th when as described before temperature Tr of first preset time t 1 is reached in the time t If temperature range (- ∞, Troff] time control ice making case 100 enter the freezing refrigerating state.
