Since according to an embodiment of the invention refrigerator except typical refrigeration and refrigerating chamber (promptly, refrigeration and refrigerating chamber R and F) outside also comprise auxiliary refrigerating chamber CR and auxiliary refrigerating chamber CF, therefore employed defrosting mode is applied to refrigerator and can carries out the defrost operation of refrigerator when not making any modification continually in the refrigerator with two typical storerooms.Therefore, the reduction of cooling effectiveness may appear.Therefore, controller 302 will consider the mode of operation separately of four storeroom R, CR, F and CF and carries out the control operation that is used for defrost operation, so that the defrost operation time of defrost operation and frequency reduce to minimum, and therefore makes cooling effectiveness increase to maximum.
Fig. 4 is a kind of flow chart that be used to control the method for the refrigerator that as mentioned above have a plurality of storerooms of explanation according to the embodiment of the invention.As shown in Figure 4, described controlling method for refrigerator consideration " defrost operation state the preceding ", " overload of refrigeration or refrigerating chamber " and " mode of operation of auxiliary refrigeration and refrigerating chamber " are carried out the defrost operation pattern.Promptly, according to controlling method for refrigerator according to the embodiment of the invention, for example, determine whether and to defrost to a part of storeroom or whole storeroom according to " defrost operation state the preceding ", " overload of refrigeration or refrigerating chamber " and " mode of operation of auxiliary refrigeration and refrigerating chamber ".Also determine whether to exist storeroom with similar temperature range.When existence had the storeroom of similar temperature range, these storerooms formed one group.Optionally carry out defrost operation for storeroom in groups.According to this controlling method for refrigerator, the reduction of the cooling effectiveness that may occur when with independent mode each storeroom being carried out defrost operation is minimized.Particularly, in controlling method for refrigerator, be determined when being in overload, can defrost to all storerooms simultaneously when being set to a specific storeroom with reference to storeroom according to the embodiment of the invention.On the other hand, when determining not to be in overload, jointly in groups storeroom is defrosted with reference to storeroom.Only for reference, " R " among Fig. 4, " CR ", " F " and " CF " represent refrigerating chamber R, auxiliary refrigerating chamber CR, refrigerating chamber F and auxiliary refrigerating chamber CF respectively.
According to described controlling method for refrigerator, in operation 402, at first determine whether to carry out defrost operation.(402 places are "No" in operation) carried out current required cooling down operation and be need not to carry out defrost operation when not needing to carry out defrost operation.On the contrary, when needs carry out defrost operation (402 places are "Yes" in operation), described process moves to operation 404, wherein determines carrying out the defrost operation (F/CF) (404 places are "Yes" in operation) of refrigerating chamber/auxiliary refrigerating chamber or carrying out refrigerating chamber/auxiliary refrigerating chamber defrost operation (R/CR) (404 places are "No" in operation) in the defrost operation the preceding in the defrost operation the preceding.In the basic defrosting mode shown in Fig. 2, for example, carry out defrost operation with the order of R/CR → F/CF → R/CR → F/CF according to the refrigerator of the embodiment of the invention.
Carry out defrost operation or alternately defrost operation simultaneously according to relevant state selectivity ground, minimize so that carry out unnecessary defrost operation.When each needs carry out defrost operation, all simultaneously all four storeroom R, CR, F and CF being defrosted, the problem that exists is or even the storeroom or the compartment that do not need to carry out defrost operation can be defrosted, thereby causes the reduction of cooling effectiveness and the increase of electric power consumption.
When defrost operation the preceding is the defrost operation (R/CR) of the defrost operation (F/CF) of refrigerating chamber/auxiliary refrigerating chamber or refrigerating chamber/auxiliary refrigerating chamber, can be in overload following time at refrigerating chamber R or refrigerating chamber F all storerooms are carried out simultaneously defrost operations (R/CR/F/CF) (in operation 406 or to operate 408 places be "Yes") (operation 410).
The overload of refrigerating chamber R is corresponding to a kind of situation, wherein when the operating time of the compressor of being accumulated afterwards at the defrost operation (F/CF) of finishing refrigerating chamber/auxiliary refrigerating chamber 202 approximately surpassed 4 hours, cooling fan 208R can be from about 2 hours of described time point ongoing operation or more of a specified duration.The operating time of the compressor of being accumulated afterwards at the defrost operation (R/CR) of finishing refrigerating chamber/auxiliary refrigerating chamber 202 is when approximately surpassing 4 hours, when compressor 202 can make refrigerating chamber F overload occur from about 2 hours of described time point ongoing operation or when more of a specified duration.
When the variation of the state of cooling that needing except the overload of refrigerating chamber R, to occur refrigerating chamber fan 208R ongoing operation during the ongoing operations in 2 hours of checking refrigerating chamber fan 208R, for example change the design temperature of refrigerating chamber R, count value for ongoing operation in 2 hours is initialised, with prevent for the overload of refrigerating chamber R really normal root be subjected to the influence of the operation of refrigerating chamber fan 208R according to the state of cooling that changes.Equally, when the variation of the state of cooling that compressor 202 ongoing operations needing during the ongoing operations in 2 hours of checking compressor 202, except the overload of refrigerating chamber F, to occur, for example change the design temperature of refrigerating chamber F, count value for ongoing operation in 2 hours of compressor 202 is initialised, with prevent for the overload of refrigerating chamber F really normal root be compressed the influence of the operation of machine 202 according to the state of cooling that changes.
When refrigerating chamber R or refrigerating chamber F are in overload, all refrigerating chamber R, auxiliary refrigerating chamber CR, refrigerating chamber F and auxiliary refrigerating chamber CF are carried out defrost operation (R/CR/F/CF) simultaneously.The overload of refrigerating chamber R or refrigerating chamber F means the compressor 202 or the refrigerating chamber fan 208R ongoing operation scheduled time or more of a specified duration, and this is because the quantity of food that will cool off among refrigerating chamber R or the refrigerating chamber F is very big.Owing to can in refrigerating chamber R or refrigerating chamber F, form a large amount of frosts under this overload, even therefore can determine when fan 208R and 208F ongoing operation, under overload, also can't obtain the sufficient air circulation.Therefore, when refrigerating chamber R or refrigerating chamber F were in overload, the time point place that carries out defrost operation at needs carried out defrost operation (R/CR/F/CF) simultaneously to all refrigerating chamber R, auxiliary refrigerating chamber CR, refrigerating chamber F and auxiliary refrigerating chamber CF.Formed frost amount is greater than formed frost amount under other state under the overload.Therefore, when under overload, carrying out alternately defrost operation, can intermittently defrost to each storeroom with the order of F/CF → R/CR → F/CF → R/CR.As a result, fully each storeroom is not defrosted, make frost still remain in the storeroom.This frost can cause the temperature of storeroom to raise.Therefore, under overload, all storerooms are carried out while defrost operation (R/CR/F/CF) to improve defrosting efficiency.
When determining that defrost operation is the defrost operation (F/CF) (404 places are "Yes" in operation) of refrigerating chamber/auxiliary refrigerating chamber the preceding, refrigerating chamber R and refrigerating chamber F all are not in overload (406 places are "No" in operation), and when the design temperature of auxiliary refrigerating chamber CF is higher than 0 ℃ (412 places are "No" in operation), only refrigerating chamber R, auxiliary refrigerating chamber CR and auxiliary refrigerating chamber CF are carried out defrost operation (414) simultaneously.When defrost operation the preceding is the defrost operation (F/CF) (404 places are "Yes" in operation) of refrigerating chamber/auxiliary refrigerating chamber, and when refrigerating chamber R and refrigerating chamber F all are not in overload (406 places are "No" in operation), execution is next to the defrost operation of " F/CF " in the basic defrost operation pattern of R/CR → F/CF → R/CR → F/CF, that is the defrost operation (R/CR) of refrigerating chamber/auxiliary refrigerating chamber.When the design temperature of auxiliary refrigerating chamber CF was higher than 0 ℃, although the internal temperature of auxiliary refrigerating chamber CF is higher than 0 ℃, yet the temperature of the evaporimeter 206CF of auxiliary refrigerating chamber can not be higher than 0 ℃.Therefore, frequently formation is white on the surface of the evaporimeter 206CF that assists refrigerating chamber owing to the temperature difference between the internal temperature of the evaporimeter 206CF that assists refrigerating chamber CF and auxiliary refrigerating chamber.Therefore, under above-mentioned state, auxiliary refrigerating chamber CF is carried out defrost operation with the defrost operation (R/CR) of refrigerating chamber/auxiliary refrigerating chamber.
On the other hand, when defrost operation the preceding is the defrost operation (F/CF) (404 places are "Yes" in operation) of refrigerating chamber/auxiliary refrigerating chamber, refrigerating chamber R and refrigerating chamber F all are not in overload (406 places are "No" in operation), and when the design temperature of auxiliary refrigerating chamber CF is not higher than 0 ℃ (412 places are "Yes" in operation), at first to carry out the defrost operation (R/CR) of refrigerating chamber/auxiliary refrigerating chamber, then carry out the mode of the defrost operation (F/CF) of refrigerating chamber/auxiliary refrigerating chamber and alternately carry out the defrost operation (R/CR) of refrigerating chamber/auxiliary refrigerating chamber and the defrost operation (F/CF) (operation 416) of refrigerating chamber/auxiliary refrigerating chamber.When the design temperature of determining auxiliary refrigerating chamber CF is not higher than 0 ℃ (412 places are "Yes" in operation), when defrost operation the preceding is the defrost operation (F/CF) (404 places are "Yes" in operation) of refrigerating chamber/auxiliary refrigerating chamber, and when refrigerating chamber R and refrigerating chamber F all are not in overload (406 places are "No" in operation), the lip-deep frost amount of the evaporimeter 206CF of auxiliary refrigerating chamber is very little, this is because the temperature of the evaporimeter 206CF of the internal temperature of auxiliary refrigerating chamber CF and auxiliary refrigerating chamber all is not higher than 0 ℃, and therefore makes the difference between auxiliary refrigerating chamber CF and the evaporimeter 206CF very little.Therefore, carry out the basic defrost operation pattern of R/CR → F/CF → R/CR → F/CF in the mode of at first carrying out the defrost operation that in the basic defrost operation pattern of R/CR → F/CF → R/CR → F/CF, is right after " F/CF " (that is the defrost operation (R/CR) of refrigerating chamber/auxiliary refrigerating chamber), then carrying out the defrost operation (F/CF) of refrigerating chamber/auxiliary refrigerating chamber.
On the other hand, when determining that defrost operation is the defrost operation (R/CR) (404 places are "No" in operation) of refrigerating chamber/auxiliary refrigerating chamber the preceding in the definite operation 404 of defrost operation the preceding, refrigerating chamber R and refrigerating chamber F all are not in overload (408 places are "No" in operation), and when the design temperature of auxiliary refrigerating chamber CR is not higher than 0 ℃ (418 places are "Yes" in operation), all four storeroom R, CR, F and CF are carried out defrost operation (operation 410) simultaneously.When the design temperature of assisting refrigerating chamber CR is not higher than 0 ℃, when refrigerating chamber R and refrigerating chamber F all are not in overload, assist refrigerating chamber CR to be used as refrigerating chamber.Therefore, all four storerooms are carried out defrost operation (R/CR/F/CF) simultaneously, to obtain the abundant defrosting of whole storeroom.
On the other hand, when defrost operation the preceding is the defrost operation (R/CR) (404 places are "No" in operation) of refrigerating chamber/auxiliary refrigerating chamber, refrigerating chamber R and refrigerating chamber F all are not in overload (408 places are "No" in operation), and when the design temperature of auxiliary refrigerating chamber CR is higher than 0 ℃ (418 places are "No" in operation), at first to carry out the defrost operation (F/CF) of refrigerating chamber/auxiliary refrigerating chamber, then carry out the mode of the defrost operation (R/CR) of refrigerating chamber/auxiliary refrigerating chamber and alternately carry out the defrost operation (F/CF) of refrigerating chamber/auxiliary refrigerating chamber and the defrost operation (R/CR) (operation 420) of refrigerating chamber/auxiliary refrigerating chamber.When the design temperature of auxiliary refrigerating chamber CR is higher than 0 ℃ (418 places are "No" in operation), defrost operation is the defrost operation (R/CR) (404 places are "No" in operation) of refrigerating chamber/auxiliary refrigerating chamber the preceding, and when refrigerating chamber R and refrigerating chamber F all are not in overload (408 places are "No" in operation), mean that auxiliary refrigerating chamber CR is used as common refrigerating chamber, making does not need to carry out defrost operation.Therefore, in this case, carry out the basic defrost operation pattern of R/CR → F/CF → R/CR → F/CF in the mode of at first carrying out the defrost operation that in the basic defrost operation pattern of R/CR → F/CF → R/CR → F/CF, is right after " R/CR " (that is the defrost operation (F/CF) of refrigerating chamber/auxiliary refrigerating chamber), then carrying out the defrost operation (R/CR) of refrigerating chamber/auxiliary refrigerating chamber.
