The principle set above-mentioned defrosting method below is described in detail:
For refrigerating appliance, the temperature between storeroom is can be interactional.If when a storageHiding room defrost to terminate, and then another storeroom shuts down defrost, then it would be possible to cause previous defrostThe temperature of storeroom again go up, the most specified maximum temperature.Here specified maximum temperature,The peak of the temperature range that corresponding storeroom can reach, such as turn-on temperature.If the temperature of storeroomDegree is long-time higher than specified maximum temperature, and food or other article will lose due cold preservation or freezing environment,And it is unfavorable for food preservation.
In the present embodiment, such as Fig. 1, no matter cold-producing medium flows in the first branch road L1 or the second branch road L2Time dynamic, finally it is required for flowing to cool down the second vaporizer 22 of the second storeroom 21, say, that theTwo vaporizers 22 are the common return of refrigerating circuit.
When the second storeroom 21 is when carrying out defrost, need to stop freezing to the second storeroom 21, firstStoreroom 11 then can not freeze, therefore second storeroom 21 defrost temperature to the first storeroom 11The impact of degree is relatively big, i.e. refrigerating chamber defrost is bigger on the impact of ice temperature room.Therefore, when the first storeroom 11After defrost terminates, needed to wait for for the first appointment time, in during this period of time, then the first storeroom 11 is recovered systemCold, treat the temperature of the first storeroom 11 be reduced to a certain degree (such as temperature reach above-mentioned first specify temperatureDegree) after, if the second storeroom 21 has defrost demand, just the second storeroom 21 is carried out defrost, noThen, after terminating due to the first storeroom 11 defrost, its temperature rises, if now start the second storage at onceHide the defrost of room 21, then the temperature of the first storeroom 11 can be caused to continue to raise, even overflow constant temperatureDegree scope.
Wherein, the first appointment time typically could be arranged to several hours, such as 5～8 hours.First refers toFixed temperature is typically set in below the specified maximum temperature of the second storeroom 21.
When the first storeroom 11 is when carrying out defrost, it is not necessary to the second storeroom 21 to be stopped refrigeration, pressureContracting machine 31 still can be started shooting, and the second storeroom 21 can recover refrigeration, therefore after defrost terminates immediatelyThe temperature of the second storeroom 21 is affected less by the defrost of the first storeroom 11, say, that if neededCold room is carried out defrost, owing to the defrost of cold room does not affect the refrigeration of refrigerating chamber, therefore to freezingIt is less that the temperature of room affects nature.The most in certain embodiments, if only considering the second storeroom 21Temperature, then without the waiting time, and directly can carry out defrost to the first storeroom 11.The most notNeed to arrange the second appointment time, the second assigned temperature, and the second temperature detecting module.
But owing to the temperature of storeroom is the highest, during refrigeration, the input power of compressor is the biggest, the second storeroomAfter defrost terminates, the temperature of storage ambient is higher, needs bigger power, if the most immediately to firstStoreroom starts defrost, it is likely that can cause the too high even overburden of power of refrigerating appliance.
Therefore, in the present embodiment, before starting the first storeroom 11 defrost, also judge from secondStoreroom 21 defrost has terminated whether the waiting time of process reached for the second appointment time, and determines whetherWhether the temperature of the second storeroom 21 is down to the second assigned temperature, the while of to avoid with heater and compressorRun and cause power excessive.Thus, after the second storeroom 21 defrost terminates, though the first storageThere is defrost demand room 11, as long as second specifies the time for meeting or the second assigned temperature not met, the most notStart the first storeroom 11 defrost.
In the present embodiment, the first assigned temperature, the second assigned temperature and first specify the time, secondThe concrete numerical value of appointment time can be obtained through test in design, manufacture process by manufacturer, and in advanceFirst input in the control system of refrigerating appliance.For the refrigerating appliance of a certain model, its first appointment temperatureDegree, the second assigned temperature and the first appointment time, the second appointment time are usually a constant, and i.e. oneThe individual changeless time period.In other embodiments, the first assigned temperature, the second assigned temperature andFirst specify the time, second specify the time can also be by control system along with the service condition of refrigerating applianceIntelligent adjustment.But the setting of these numerical value it suffices that, when a storeroom defrost, another storageThe temperature of room without departing from specified maximum temperature, and/or, the power of refrigerating appliance will not be excessive.Here " mistakeGreatly ", the rated maximum power beyond equipment can be referred to, or beyond the power upper limit being manually set.
In other embodiments, the first assigned temperature, the second assigned temperature and first specify the time, theTwo arranging of time of appointment can more loosely, such as a certain storeroom, if exceeded in short timeSpecified maximum temperature be allow, then the first assigned temperature, the second assigned temperature can be higher,Or first specify the time, second specify the time can be the most shorter, such as, if timing unitTiming has when necessarily postponing, then first specify the time, second specify the time can also be more slightly shorter, but allMust be limited not affect refrigeration.
Showing when the second storeroom 21 defrost with reference to Fig. 4, Fig. 4, the temperature of the first storeroom 11 becomesThe changed power situation of change situation and refrigerating appliance.Wherein abscissa represents the time, vertical coordinate generation respectivelyThe power of table refrigerating appliance and the temperature of the first storeroom 11, curve 1 is the power curve of refrigerating appliance,Curve 2 is the temperature curve of the first storeroom 11, and curve 3 is the specified highest temperature of the second storeroom 21Degree line, curve 4 is the peak power line specified of refrigerating appliance, and T1 is that the first storeroom 11 defrost terminatesTime, T2 is that the second storeroom 21 defrost starts the time, and the difference of T2 Yu T1 is Δ T, and Δ T is waitTime, wherein waiting time Δ T is more than or equal to the first appointment time.
Figure 4, it is seen that after waiting time Δ T reached for the first appointment time, the second storeroomDuring 21 beginning defrost, the temperature of the first storeroom 11 is able to maintain that below specified maximum temperature, thus protectsDemonstrate,prove its refrigeration；Within the power of refrigerating appliance can also remain at the peak power specified simultaneously.NeedIt should be noted that " waiting time reached for the first appointment time " simply starts the second storeroom 21 defrostEssential condition, but be not sufficient condition, say, that " waiting time reached for the first appointment time " isStart one of condition of the second storeroom 21 defrost.
Such as Fig. 2, Fig. 3, start refrigerating appliance defrost and also need to judge whether the storeroom of correspondence has defrost to needAsk, i.e. determine whether that starting defrost also includes other conditions, when starting the second storeroom 21/ first storeroomWhen other conditions of 11 defrosts are also satisfied by, refrigerating appliance just can start the storeroom defrost of correspondence.StartOther conditions of first storeroom 11/ second storeroom 21 defrost can also include, door opening times, compressionMachine 31 is for the single available machine time of the second storeroom 21, and compressor 31 is for the second storeroom 21Set available machine time, and/or the overall work time etc. of refrigerating appliance.Refrigerating appliance can be based on thesePart judges whether the first storeroom or the second storeroom have defrost demand, judges another storeroom the most againDefrost terminate whether to pass through predetermined time interval, if it is, start the defrost of corresponding storeroom,If it is not, wait until reaching predetermined time interval and starting again the storeroom defrost having defrost demand.
In other embodiments, the first assigned temperature, the second assigned temperature can be not provided with, when the first storageHide room or the second storeroom when having defrost demand, only judge from another storeroom defrost terminate through etc.Whether the time for the treatment of meets the corresponding appointment time.Or, the first assigned temperature, the second finger can be only setFixed temperature, when the first storeroom or the second storeroom have defrost demand, only judges from another storeroomWhether temperature meets corresponding assigned temperature.
With reference to Fig. 1 and combine 5, the embodiment of the present invention also provides for a kind of defrosting control system for refrigerating applianceSystem, refrigerating appliance includes the first storeroom 11 and the second storeroom 21 that can distinguish defrost.Wherein freezeThe concrete structure of utensil can refer to Fig. 1, and in refrigerating circuit, the setting of each parts can refer to aforementioned for Fig. 1'sDescribe, do not repeat them here.
Such as Fig. 5-6, defrosting control system includes:

Performance element starts the condition of the second storeroom 21 defrost and includes: the first actual time was more than or equal toFirst specifies the time.
The present invention specifies the time as one of entry condition of the second storeroom defrost, the i.e. second storage using firstHide room after the first storeroom defrost terminates, defrost can be started after certain wait again, and in this sectionIn waiting time, the first storeroom can recover refrigeration so that it is temperature reduces, and then reaches when the waiting timeAfter the first appointment time, restart the second storeroom defrost, to during to reduce the second storeroom defrostThe temperature impact of one storeroom, it is to avoid the temperature of the first storeroom is too high.
Further, defrosting control system also includes temperature detecting unit, and temperature detecting unit includes firstTemperature detecting module, for the temperature of detection the first storeroom 11, and obtains the first actual temperature；StorageUnit is additionally operable to store the first assigned temperature that user sets；Comparing unit is additionally operable to compare the first appointment temperatureDegree and the first actual temperature；Performance element starts the condition of the second storeroom 21 defrost and includes: the first storageThe temperature of room 11 is less than or equal to the first assigned temperature.
Using the first assigned temperature as one of the entry condition of the second storeroom 21 defrost, the most only firstIt is possible to the second storeroom 21 is started when the temperature of storeroom 11 is less than or equal to the first assigned temperatureDefrost, when reducing the second storeroom 21 defrost further, the temperature on the first storeroom 11 affects.
Show that defrosting control system controls the operation principle of the second storeroom 21 defrost with reference to Fig. 6, Fig. 6.At the end of first storeroom 11 defrost, timing unit starts timing, obtained for the first actual time, and by thanFirst actual time and the first appointment time are compared by relatively unit: reach first when the first actual timeDuring the appointment time, producing timing signal and timing signal is sent to performance element, performance element will meterTime signal as one of condition starting the second storeroom 21 defrost.Meanwhile, temperature detecting unit detection theThe temperature of one storeroom 11, and obtain the first actual temperature, and by comparing unit by the first actual temperature andFirst assigned temperature compares: when the first actual temperature is down to the first assigned temperature, produces temperature letterNumber and temperature signal is sent to performance element, performance element using temperature signal as start second storageOne of condition of room 21 defrost.Wherein, performance element can include some modules, be respectively used to receive/ send signal, and be used for controlling storeroom startup or terminating defrost.
Further, memory element is additionally operable to store the second appointment time that user sets；Timing unit is alsoFor starting timing at the end of the second storeroom 21 defrost, and obtained for the second actual time；Comparing unitIt is additionally operable to compare the second appointment time and the second actual time；Performance element starts the first storeroom 11 defrostCondition include: the second actual time more than or equal to second appointment the time.
Specify the time as one of entry condition of the first storeroom 11 defrost, the i.e. first storage using second hereinHide room 11 and after the second storeroom 21 defrost terminates, defrost can be started after certain wait again, andWithin this period of waiting time, the second storeroom 21 can recover refrigeration so that it is temperature reduce, then when etc.After the time reached for the second appointment time, restart the first storeroom 11 defrost, to reduce the first storeroomDuring 11 defrost, the temperature on the second storeroom 21 affects, it is to avoid the temperature of the second storeroom 21 is too high.
Further, memory element is additionally operable to store the second assigned temperature that user sets；Temperature detection listUnit also includes the second temperature detecting module of the temperature for detecting the second storeroom 21, and it is real to obtain secondBorder temperature；Comparing unit is additionally operable to compare the second assigned temperature and the second actual temperature；Performance element startsThe condition of the first storeroom 11 defrost includes: the temperature of the second storeroom 21 is less than or equal to the second appointmentTemperature.
Using the second assigned temperature as one of the entry condition of the first storeroom 11 defrost, the most only secondIt is possible to the first storeroom 11 is started when the temperature of storeroom 21 is less than or equal to the second assigned temperatureDefrost, when avoiding the first storeroom defrost further, the temperature on the second storeroom affects.
The first storeroom is controlled for being illustrated defrosting control system in the second with reference to Fig. 7, Fig. 711The operation principle of defrost.At the end of second storeroom 21 defrost, timing unit starts timing, obtains theTwo actual tives, and compared by the second actual time of comparing unit and the second appointment time.When secondWhen reaching for the second appointment time actual time, produce timing signal and be sent to perform list by timing signalUnit, performance element using timing signal as one of condition starting the first storeroom 11 defrost.Meanwhile, temperatureDegree detector unit detects the temperature of the second storeroom 21, and obtains the second actual temperature, and by comparing unitSecond actual temperature and the second assigned temperature are compared: when the second actual temperature is down to the second appointment temperatureWhen spending, producing temperature signal and temperature signal is sent to performance element, performance element is by temperature signalAs one of condition starting the first storeroom 11 defrost.
In the present embodiment, the first assigned temperature, the second assigned temperature and first specify the time, secondThe concrete numerical value of appointment time can be obtained through test in design, manufacture process by manufacturer, and in advanceFirst input in the control system of refrigerating appliance.For the refrigerating appliance of a certain model, its first appointment temperatureDegree, the second assigned temperature and the first appointment time, the second appointment time are usually a constant, and i.e. oneThe individual changeless time period.In other embodiments, the first assigned temperature, the second assigned temperature andFirst specify the time, second specify the time can also be by control system along with the service condition of refrigerating applianceIntelligent adjustment.But the setting of these numerical value it suffices that, when a storeroom defrost, another storageThe temperature of room without departing from specified maximum temperature, and/or, the power of refrigerating appliance will not be excessive, " mistake hereGreatly ", the rated maximum power beyond equipment can be referred to, or beyond the power upper limit being manually set.
In other embodiments, the first assigned temperature, the second assigned temperature and first specify the time, theTwo arranging of time of appointment can more loosely, such as a certain storeroom, if exceeded in short timeSpecified maximum temperature be allow, then the first assigned temperature, the second assigned temperature can be higher,Or first specify the time, second specify the time can be the most shorter, such as, if timing unitTiming has when necessarily postponing, then first specify the time, second specify the time can also be more slightly shorter, but allMust be limited not affect refrigeration.
If as before, when a storeroom defrost terminates, and and then another storeroom shuts down defrost, thenIt would be possible to cause the temperature of the storeroom of previous defrost again to be gone up, exceed specified maximum temperature, causeMaking food or other article will lose due cold preservation or freezing environment, time one length then can cause refrigeration to be lostEffect.Therefore the present embodiment is disposed therein after a storeroom defrost terminates, and must wait until that its temperature is down to oneAfter determining degree, then can carry out the defrost of another storeroom, to ensure refrigeration.
As previously described, because the temperature of the first storeroom 11 is affected relatively big by the defrost of the second storeroom 21,Therefore select to arrange the first assigned temperature.And the temperature that the defrost of the first storeroom 11 is to the second storeroom 21Degree impact is less, the most in other embodiments, after the first storeroom 11 defrost terminates, the second storageBefore room 21 starts defrost, it is also possible to do not judge the temperature of the second storeroom, once the first having of storeroomFrost request then starts its defrost, as long as the power of refrigerating appliance will not be excessive.
It should be noted that " temperature of storeroom is down to assigned temperature " simply starts a certain storeroom defrostEssential condition, but be not necessarily sufficient condition, say, that the temperature conditions of storeroom can beStart one of condition of a certain storeroom defrost.Such as Fig. 6, Fig. 7, start refrigerating appliance defrost and also need to sentenceDisconnected corresponding storeroom is with or without defrost demand, when the second storeroom 21/ first storeroom 11 has defrost demandTime, refrigerating appliance just can start the storeroom defrost of correspondence.Need by other conditions with or without defrost demandJudging, other conditions starting the second storeroom 21 defrost can also include heater on time, openDoor number of times, compressor 31 are for the single available machine time of the second storeroom 21, and compressor 31 is for secondThe set available machine time of storeroom 21, and the overall work time etc. of refrigerating appliance.
In other embodiments, first vaporizer the 12, second vaporizer 12 of refrigerating appliance can also be in parallel,Then, cold-producing medium only flows to the first vaporizer 12 to cool down the first storeroom 11, or only flows to the second evaporationDevice 22 is to cool down the second storeroom 21.
Now, substantially it is independent of each other between the first vaporizer 12 and the second vaporizer 22, a therefore storageThe defrost hiding room is little on the impact of another storage compartment temperature.But it is same in order to avoid compressor 31 input workRate is too high, after a storeroom defrost terminates, after its temperature is reduced to assigned temperature, restarts anotherOne storeroom carries out defrost, to reduce the input power of compressor.It is to say, institute in the present embodimentDefrosting method and the defrosting control system stated still are suitable for.
In other embodiments, defrosting control system can only be judged by temperature or waiting time beNo startup a certain storeroom defrost.
The embodiment of the present invention also provides for a kind of refrigerating appliance, and it includes the defrosting control system of any of the above-described.
Second embodiment
With reference to Fig. 8, the defrosting method of the present embodiment is identical with embodiment one, and the difference with above-described embodiment existsIn, the refrigerating appliance of this enforcement includes three storerooms, respectively cold room a1, ice temperature room b1, freezingRoom c1, and for cooling down the refrigerator evaporator a2 of cold room a1, ice temperature room vaporizer b2 and coldFreeze room vaporizer c2.
The arrival end of three vaporizers a2, b2, c2 is connected in parallel, and refrigerating circuit includes having cold roomThe first branch road L1 of vaporizer a2, there is the second branch road L2 of ice temperature room vaporizer b2, and have coldFreeze the 3rd branch road L3 of room vaporizer c2.First branch road L1 refrigerator evaporator a2 the port of export,Two branch road L2 are connected to the 3rd branch road L3 at freezer evaporator at the port of export of ice temperature room vaporizer b2The port of export of c2.
Now, refrigerating appliance has mixed cold three-circulation refrigerating system.
Refrigerating circuit has three mode of operations.
In the first operation mode, the first branch road L1: refrigerant flow direction cold preservation opened by electromagnetic valve 341,342Room vaporizer a2, to cool down cold room a1, then flows out from refrigerator evaporator a2 and flows into refrigerating chamber and steamSend out device from c2 to cool down refrigerating chamber c1；
In the second operation mode, the second branch road L2: refrigerant flow direction ice temperature opened by electromagnetic valve 341,342Room vaporizer b2, to cool down ice temperature room b1, flows out from ice temperature room vaporizer b2 after people and flows into refrigerating chamber and steamSend out device from c2 to cool down refrigerating chamber c1；
In the third mode of operation, the 3rd branch road L3 opened by electromagnetic valve 341,342: cold-producing medium only flows into coldFreeze room vaporizer c2, and be not passed through refrigerator evaporator a2, ice temperature room vaporizer b2.
With this, refrigerating circuit can switch between three mode of operations.
Wherein it is possible to two storerooms will the most arbitrarily be chosen, and using one of them as the first storage it is,Another, as the second storeroom, is then suitable for defrosting method and the defrosting control system of first embodiment.It can be seen that no matter cold-producing medium first passes through cold room a1 or through ice temperature room b1, the most all through supercoolLoop and circulation is realized, say, that in whole refrigerating circuit, freezer evaporator c2 after freezing room c1As common return.
As can be seen here, when refrigerating chamber c1 defrost, because freezer evaporator c2 is common return, nowCompressor 31 needs to stop, and cold room a1 and ice temperature room b1 can not freeze；
And during cold room a1 defrost, compressor 31 can be started shooting, refrigerating chamber c1 and ice temperature room b1 continues systemCold, thus by temperature affected less.
During same ice temperature room b1 defrost, refrigerating chamber c1 and cold room a1 continues refrigeration, the temperature shadow being subject toRing the least.
Visible, for such refrigerating appliance, to other storeroom during refrigerating chamber c1 defrostTemperature impact is relatively big, and the waiting time can arrange longer.And cold room a1 and ice temperature room b1 two storageHide the defrost between room little on the impact of temperature each other, the temperature of refrigerating chamber c1 is affected the least, during waitBetween can arrange the most shorter, it might even be possible to be not provided with the waiting time, but institute in first embodimentState, within now reasonably the waiting time can make the power of refrigerating appliance maintain the peak power specified.
In practical operation, if estimate the temperature of storeroom with the length of waiting time, the most all storagesThe waiting time hiding the defrost between room can be unified to set unanimously, so can simplify program.
Although present disclosure is as above, but the present invention is not limited to this.Any those skilled in the art,Without departing from the spirit and scope of the present invention, all can make various changes or modifications, therefore the guarantor of the present inventionThe scope of protecting should be as the criterion with claim limited range.
