Specific implementation mode

Technical solution to further illustrate the present invention below with reference to the accompanying drawings and specific embodiments.

Embodiment one

Referring to Fig.1, in the present embodiment, single cycle refrigerator includes refrigerating chamber, freezing chamber, refrigerator evaporator and compression The temprature control method of machine, single cycle refrigerator specifically includes：When refrigerating chamber has refrigeration demand, compressor is opened；Work as freezing chamber When having refrigeration demand, individually to refrigerating chamber heating until refrigerating chamber has refrigeration demand.

As a result, the temprature control method of the present embodiment be not realize more function of temperature control by increasing capillary and valve, and It is the temperature by first increasing refrigerating chamber when freezing chamber has refrigeration demand so that refrigerating chamber and freezing chamber have refrigeration to need simultaneously It asks, is then then turned on compressor and integrally cools down.To sum up, the characteristics of present invention is by bonding machine control refrigerator, using refrigeration Room controls the temperature of entire refrigerator.

The temperature that each compartment in single cycle refrigerator is controlled using the above method is abandoned while realizing more function of temperature control The capillary and valve for realizing the function in the prior art, greatly reduce material cost.In addition, will not occur valve body leakage or Blocking causes some compartment of refrigerator not freeze or do not shut down, cause the problem of customer complaint, and will not be connect because of capillary wrong It needs to do over again instead and then brings economic loss.Also, it can be greatly simplified using the manufacturing process of the refrigerator of the temprature control method, Manufacturing cost can also reduce.

Further, referring to Fig.1, in the present embodiment, when temperature of refrigerating chamber LC is more than or equal to refrigerating chamber ceiling temperature LCon And when refrigerator evaporator temperature LCZ is more than or equal to refrigerator evaporator set temperature LCZo, being considered as refrigerating chamber has refrigeration to need It asks.Wherein, being just considered as when being set in refrigerator evaporator temperature LCZ more than refrigerator evaporator set temperature LCZo has refrigeration to need Ask, can prevent refrigerator evaporator when being switched on again above the frost tied do not melt, and then prevent from so recycling finally make it is cold The a large amount of frostings of room evaporator are hidden, causes refrigeration effect bad or does not freeze.

Specifically, refrigerating chamber ceiling temperature LCon is determined according to refrigerating chamber desired temperature set by user, for example, user Temperature of refrigerating chamber LC is set as 4 DEG C, then can refrigerating chamber ceiling temperature Lcon be set as 5 DEG C accordingly.Certainly, on refrigerating chamber Limit temperature Lcon selects how much to be suitable according to refrigerating chamber desired temperature set by user, is well known to those skilled in the art, It is only illustrated herein without limiting.

In addition, presetting refrigerator evaporator set temperature LCZo, refrigerator evaporator set temperature LCZo is solid Definite value, such as 5 DEG C.Refrigerator evaporator set temperature LCZo, which is intended to cooling, so that refrigerator evaporator is largely frozen, because This, suitable fixed value can be arranged according to actual condition in those skilled in the art, only illustrated herein without limiting.

Further, in the present embodiment, following three kinds of situations are divided into freezer temperature control：

The first situation, when freezer temperature LD is more than or equal to the first freezing chamber set temperature LD1 and cold less than second When freezing room set temperature LD2, being considered as freezing chamber has refrigeration demand；

The second situation, when freezer temperature LD is more than or equal to the second freezing chamber set temperature LD2 and cold less than third Freeze room set temperature LD3, temperature of refrigerating chamber LC to be less than refrigerating chamber ceiling temperature LCon and be more than the first refrigerating chamber set temperature When LC1 and refrigerator evaporator temperature LCZ is more than or equal to refrigerator evaporator set temperature LCZo, compressor is opened；

The third situation opens compressor when freezer temperature LD is more than or equal to third freezing chamber set temperature LD3.

Wherein, the first freezing chamber set temperature LD1 is less than the second freezing chamber set temperature LD2, the second freezing chamber setting temperature It spends LD2 and is less than third freezing chamber set temperature LD3, being divided into normal refrigeration demand situation as a result, (freezer temperature is more than or equal to the One freezing chamber set temperature LD1 simultaneously be less than the second freezing chamber set temperature LD2), the higher situation of temperature (freezer temperature be more than etc. In the second freezing chamber set temperature LD2 and it is less than third freezing chamber set temperature LD3) and thermo-field thoery situation (freezing room temperature Degree is more than or equal to third freezing chamber set temperature LD3).

Corresponding to normal refrigeration demand situation：First freezing chamber set temperature LD1 is expected according to freezing chamber set by user Temperature determines, such as user sets freezer temperature LD as -16 DEG C, then ceiling temperature that freezing chamber need to freeze (namely first Freezing chamber set temperature LD1) it may be configured as -15 DEG C.Certainly, the ceiling temperature that freezing chamber need to freeze is according to freezing set by user It is how many suitable that room desired temperature is determined as, and is well known to those skilled in the art, is only illustrated herein without limiting.

Corresponding to normal refrigeration demand situation, being freezing chamber has refrigeration demand, directly individually to refrigerating chamber heating until cold Hiding room has refrigeration demand, then compressor booting integrally cooling.

Temperature of refrigerating chamber compensating heater can be used wherein it is preferred to individually be heated to refrigerating chamber, for example, being with 1 minute Period opens 45 seconds, stops 15 seconds.

Wherein it is preferred to because refrigerating chamber has refrigeration demand make compressor open after, when comparing compressor continuous operation Between T and default running time T o (for example, 2 hours) stop if compressor continuous operation is more than or equal to default running time T o Compressor operating；If compressor continuous operation is less than default running time T o, compare temperature of refrigerating chamber LC and refrigerating chamber at this time Lower limit temperature LCoff, if temperature of refrigerating chamber LC is less than or equal to refrigerating chamber lower limit temperature LCoff (refrigerating chamber lower limit temperature LCoff roots Determined according to refrigerating chamber desired temperature set by user, reach refrigerating chamber lower limit temperature LCoff and illustrate that temperature of refrigerating chamber LC is too low), Then close compressor restores shutdown status, if temperature of refrigerating chamber LC is more than refrigerating chamber lower limit temperature LCoff, keeps compressor It opens and returns to the step of comparing compressor continuous operating time T and default running time T o.Wherein, running time T o purports are preset In protection compressor, therefore, concrete numerical value those skilled in the art can determine according to actual condition, only illustrate herein and unlimited It is fixed.When refrigerating chamber desired temperature is 4 DEG C, refrigerating chamber lower limit temperature LCoff is 3 DEG C.Certainly, refrigerating chamber lower limit temperature LCoff It is selected how much to be suitable according to refrigerating chamber desired temperature set by user, is well known to those skilled in the art, only lifts herein Example is without limiting.

Corresponding to the higher situation of temperature：The temperature of refrigerating chamber slightly rises caused by user opens the operations such as the door of refrigerating chamber meeting Up to it is more than the temperature (i.e. the first freezing chamber set temperature LD1) of normal refrigeration demand.Suitable for such case, the second freezing chamber Set temperature LD2 determines according to the first freezing chamber set temperature LD1, can preset the second freezing chamber set temperature LD2 be A rational temperature value (such as 2-5 DEG C) is increased on the basis of first freezing chamber set temperature LD1, is chosen in the present embodiment 2 DEG C, it is, when the first freezing chamber set temperature LD1 is -15 DEG C, the second freezing chamber set temperature LD2 is -11 DEG C.When So, the specific choice of above-mentioned rational temperature value, those skilled in the art can determine according to actual condition, as long as table can be corresponded to The above situation is shown, is only illustrated herein without limiting.

Corresponding to the higher situation of temperature, need to consider temperature of refrigerating chamber LC and refrigerator evaporator temperature LCZ.Specifically, If temperature of refrigerating chamber LC is less than refrigerating chamber ceiling temperature LCon and more than the first refrigerating chamber set temperature LC1 and refrigeration When room evaporator temperature LCZ is more than or equal to refrigerator evaporator set temperature LCZo, compressor cooling can be opened.Wherein, first Refrigerating chamber set temperature LC1 is preset fixed value, which is suitably less than refrigerating chamber ceiling temperature LCon.Refrigerating chamber Temperature LC illustrates that refrigerating chamber can suitably cool down between the first refrigerating chamber set temperature LC1 and refrigerating chamber ceiling temperature LCon. Likewise, refrigerator evaporator temperature LCZ is more than or equal to refrigerator evaporator set temperature LCZo, illustrate that cooling will not make refrigeration Room evaporator largely freezes.Wherein, for example, the first refrigerating chamber set temperature LC1 is 2 DEG C, certainly, the first refrigerating chamber set temperature LC1 be set as how much the lower limit standard that can suitably cool down as refrigerating chamber, be well known to those skilled in the art, herein only Citing is without limiting.

In general, correspond to the higher situation of temperature, if refrigerating chamber can suitably cool down, and cooling will not make refrigerating chamber If evaporator largely freezes, so that it may integrally be cooled down with opening compressor, that is to say, that give priority to the cooling of freezing chamber at this time Demand；If refrigerating chamber cannot cool down or cool down refrigerator evaporator can be made largely to freeze, it is not turned on compressor, also It is to say, gives priority to refrigerating chamber and refrigerator evaporator at this time.

Preferably, in the higher situation of higher temperature, after compressor is opened, compare compressor continuous operating time T with it is pre- If running time T o (for example, 2 hours), if compressor continuous operation is more than or equal to default running time T o, stop compressor Work；If compressor continuous operation is less than default running time T o, compare refrigerator evaporator temperature LCZ at this time and pre- constant temperature LCZ1 (for example, -32 DEG C) is spent, if refrigerator evaporator temperature LCZ is more than predetermined temperature LCZ1, is back to and compares compressor The step of continuous operating time T and default running time T o, if refrigerator evaporator temperature LCZ is less than or equal to predetermined temperature LCZ1, then close compressor, restores shutdown status.Wherein, predetermined temperature LCZ1 can be -20~-32 degree, choose wherein relatively low Numerical value, cooling time can be made longer, it is ensured that the temperature of freezing chamber lowers.

Corresponding to thermo-field thoery situation：Third freezing chamber set temperature LD3 is preset fixed value, which is The temperature for making the frozen goods in freezing chamber that can thaw, such as -9 DEG C.It is of course possible to which it is minimum so that the frozen goods in freezing chamber is thawed Temperature is how many, namely frozen goods can thaw when being reduced to how many, be well known to those skilled in the art, only illustrate herein without It limits.Freezer temperature LD is more than or equal to the case where third freezing chamber set temperature LD3, it may be possible to due to for example in freezing chamber In be put into caused by excessive heat load, directly open compressor, that is, the unconditionally temperature of priority acccess control freezing chamber at this time.

Preferably, in thermo-field thoery situation, after compressor is opened, compare compressor continuous operating time T and default fortune Row time To (for example, 2 hours) stops compressor operating if compressor continuous operation is more than or equal to default running time T o； If compressor continuous operation is less than default running time T o, compare at this time freezer temperature LD and preset temperature LD4 (for example,- 16 DEG C), if freezer temperature LD is more than -16 DEG C, it is back to and compares compressor continuous operating time T and default run time The step of To, compares temperature of refrigerating chamber LC at this time and refrigerating chamber lower limit temperature if freezer temperature LD is less than or equal to -16 DEG C LCoff；If temperature of refrigerating chamber LC is less than or equal to refrigerating chamber lower limit temperature LCoff, close compressor restores shutdown status, if Temperature of refrigerating chamber LC is more than refrigerating chamber lower limit temperature LCoff, then keeps compressor to open and return to compare compressor continuous operation The step of time T and default running time T o.Wherein, preset temperature LD4 is intended to indicate that the temperature of freezing chamber has already decreased to foot It is enough low, it is sufficient to meet the refrigeration demand of freezing chamber, therefore, preset temperature LD4 is set as how many suitable, is people in the art Well known to member, only illustrated herein without limiting.

Freezer temperature control is divided into above-mentioned three kinds of situations as a result, is considered from the overall situation, effective and reasonable control refrigerating chamber With the temperature of freezing chamber.

Further, if because priority acccess control freezer temperature LD or other situations make the temperature of refrigerating chamber decrease below Two refrigerating chamber set temperature LC2 can individually heat refrigerating chamber, up to the temperature recovery of refrigerating chamber to more than equal under refrigerating chamber Until limiting temperature LCoff.Wherein, the second refrigerating chamber set temperature LC2 is less than refrigerating chamber lower limit temperature LCoff certain numerical value (examples Such as 3 DEG C), it is, for example, when refrigerating chamber lower limit temperature is 3 DEG C, the second refrigerating chamber set temperature LC2 is 0 DEG C.Certainly, Two refrigerating chamber set temperature LC2 are suitable less than refrigerating chamber lower limit temperature, are well known to those skilled in the art, herein only Citing is without limiting.

Certainly, in other embodiments of the invention, also can freezer temperature LD be directly more than or equal to the first freezing chamber The case where set temperature LD1, which is considered as freezing chamber, refrigeration demand, although the higher situation of above-mentioned temperature and temperature have been abandoned in setting in this way Superelevation situation is spent, leads to the cooling relative delay of freezing chamber, but still can realize the temperature for controlling freezing chamber by refrigerating chamber Effect.

Further, in existing single cycle refrigerator, the refrigerating chamber being likely present between refrigerating chamber and freezing chamber, needle To such single cycle refrigerator, the temprature control method of the present embodiment further includes：When there is refrigeration demand in refrigerating chamber, individually to cold Room heating is hidden until refrigerating chamber has refrigeration demand.

Accordingly, for the control of refrigerating chamber's temperature, it is again based on the original for the temperature that entire refrigerator is controlled using refrigerating chamber Then.

It is considered as refrigerating chamber when refrigerating chamber temperature WD is more than or equal to refrigerating chamber ceiling temperature WDon specific to the present embodiment There is refrigeration demand.Wherein, refrigerating chamber's ceiling temperature WDon is determined according to refrigerating chamber's desired temperature set by user, for example, if Refrigerating chamber's desired temperature set by user is 0 DEG C, then refrigerating chamber ceiling temperature WDon is 1 DEG C.Certainly, refrigerating chamber's ceiling temperature WDon is set as how many suitable according to refrigerating chamber's desired temperature set by user, is well known to those skilled in the art, herein only It illustrates without limiting.

Further, if because above-mentioned priority acccess control freezer temperature or other situations make refrigerating chamber temperature WD decrease below When equal to the first refrigerating chamber set temperature WD1, individually refrigerating chamber can be heated, until refrigerating chamber temperature WD rises to and is more than or equal to Refrigerating chamber lower limit temperature WDoff.Wherein, refrigerating chamber's lower limit temperature WDoff is determined according to refrigerating chamber's desired temperature set by user； First refrigerating chamber set temperature WD1 determines that the first refrigerating chamber set temperature WD1 is than micro- jelly according to refrigerating chamber lower limit temperature WDoff The low fixed values of room lower limit temperature WDoff.For example, if refrigerating chamber's desired temperature set by user is 0 DEG C, refrigerating chamber's lower limit Temperature WDoff is -1 DEG C, and the first refrigerating chamber set temperature WD1 is 3 DEG C lower than refrigerating chamber lower limit temperature WDoff, i.e. the first refrigerating chamber Set temperature WD1 is -4 DEG C.Certainly, refrigerating chamber's lower limit temperature WDoff is set as according to refrigerating chamber's desired temperature set by user It is how many suitable, it is well known to those skilled in the art, is only illustrated herein without limiting.

Wherein, refrigerating chamber is individually heated and refrigerating chamber's temperature compensation heater can be used, for example, being opened for the period with 1 minute 45 seconds, stop 15 seconds.

It should be noted that well known to a person skilled in the art compressor is opened, and refrigeration mode is executed.If compressor The operation heated to refrigerating chamber/refrigerating chamber is executed before opening, then when opening compressor or before opening compressor It will stop the heating of refrigerating chamber/refrigerating chamber.

To sum up, in the present embodiment, it when freezing chamber and refrigerating chamber have refrigeration demand, is increased using by the temperature of refrigerating chamber To having after refrigeration demand simultaneously to entire refrigeration for refrigerator；It is special when the higher situation of temperature and thermo-field thoery situation occurs in freezing chamber Different processing；It is individually heated using respective temperature compensation heater when the temperature of refrigerating chamber and refrigerating chamber is too low.As a result, to adopt Based on controlling refrigeration for refrigerator with refrigerating chamber, auxiliary is with the special treatment method of special circumstances and to refrigerating chamber and chilly room Individually heating makes the temperature of single cycle refrigerator control more reasonable, effective.
