In above step, the opening and closing signal of door body 20 can be detected in step S302 by door body detector.Step If door body detector detects the opening and closing signal of the door body of some storage room in S304, so that it may which determining has in the storage room Food materials variation.And then can use the weight induction sensor being arranged at each support of the rack of storage room, it determines Food materials variation in the storage room is that food materials are removed or food materials are placed into.Specifically, if weight induction sensor measures Weight increase, it is believed that food materials are placed into；The weight that weight induction sensor measures reduces, then it is assumed that food materials are removed.It is eating In the case that material is placed into, the refrigerator temperature control method based on food materials of the present embodiment is executed.

In step S306 detection be placed into food materials type and weight mode can there are many, such as can use setting The type and/or weight for being placed into food materials being manually entered by user are obtained in the input unit on 100 shell of refrigerator.Input dress Setting can be using such as physical button or touch key-press, and touch screen acquisition can be used in input unit in some preferred embodiments The food materials type and/or weight information of input.The food materials weight that wherein user is manually entered can by the outer packings of food materials or Person directly measures acquisition.The available type and/or weight information for being placed into food materials being manually entered by user of input unit, It can be also used for confirming the food materials type and/or weight information that automatically identify in some optional embodiments.

The priority allocation model that food materials are placed into step S308 includes priority weights mode and compartment mode of priority, power Weight mode of priority is the weight for paying the utmost attention to food materials itself, and compartment mode of priority is then the storage for paying the utmost attention to the storage of food materials optimum Object compartment.Display screen can be set in the door body of refrigerator 100, can have been obtained by display screen and selected by user be placed into food The priority allocation model of material.

If the priority allocation model for being placed into food materials in step S310 is priority weights mode, step S312 is executed to step Rapid S334 executes the process of weight mode of priority；If the priority allocation model for being placed into food materials is not priority weights mode, It is then compartment mode of priority, executes step S336 to step S344, that is, execute the process of compartment mode of priority.

It is excellent to preserve the corresponding food materials of different types of food materials for preset food materials information bank in step S312 and step S336 First grade, compartment priority and best storage temperature.Inquiry is carried out in food materials information bank according to the type for the food materials determined Match, so that it may obtain the corresponding food materials priority of food materials, compartment priority and best storage temperature.It should be noted that different The food materials of type are according to best storage temperature distribution food materials priority from low to high.

The specific example of a food materials information bank is introduced below: the food materials in food materials information bank have Chinese cabbage, potato, Cucumber, the best storage temperature of Chinese cabbage are 0 DEG C, and the best storage temperature of potato is 3 DEG C, and the best storage temperature of cucumber is 8 DEG C, So from low to high according to best storage temperature, the food materials priority of Chinese cabbage is F1, and the food materials priority of potato is F2, cucumber Priority is F3.It should be noted that food materials priority F1 is higher than F2, F2 is higher than F3, and so on.Between different types of storing The compartment priority of room is different, if set the priority of refrigerator room as S1, the priority of alternating temperature compartment is S2, freezing compartment Priority is S3, due to Chinese cabbage be suitable for storage storage room be alternating temperature compartment, then the compartment priority of Chinese cabbage be S2, potato and Cucumber is suitable for that the storage room of storage is all refrigerator room, then the compartment priority of potato and cucumber is S1.Therefore, the food materials The information that information bank saves is as follows: Chinese cabbage, and F1/S2/0 DEG C；Potato, F2/S1/3 DEG C；Cucumber, F3/S1/8 DEG C.Above-mentioned food materials letter The form in breath library only enumerates, and not limitation of the invention.

It is placed into all former food materials in the storage room where food materials in step S314 and is being placed into storage room Shi Douyi Type and corresponding food materials priority and weight has been determined, thus can have been directly acquired.

The weight that food materials are placed into step S316 may indicate that a certain index for being placed into food materials in the overall evaluation Relative importance.In a preferred embodiment, can according to the food materials priority and weight for being placed into food materials, put The weight determination for entering food materials and food materials priority minimum in former food materials in storage room where it and all former food materials is put Enter the weight of food materials.If such as being placed into food materials priority minimum in food materials and former food materials is Fm, is placed into the food materials of food materials Priority is Fn, and the weight for being placed into food materials is M0, and the weight of all original food materials is Mt, then the weight for being placed into food materials is W, W=W1+W2, W1=(m-n)/m, W2=M0/ (M0+Mt).It should be noted that the food materials priority for being placed into food materials is higher than original In food materials when minimum food materials priority, Fm is food materials priority minimum in former food materials；It is placed into the food materials priority of food materials When less than or equal to food materials priority minimum in former food materials, Fm=Fn, W1=0.The weight for being placed into food materials is bigger, is storing up Storing effect in object compartment is more important, also should more set the target temperature of storage room to be placed into most preferably depositing for food materials Storing temperature.

In addition, after being placed into food materials and being placed into storage room, the weight of all original food materials will be into the storage room Row updates, and can be calculated according to formula W=W1+W2, if the food materials priority of certain former food materials is Fo, weight M1, Then W1=(m-o)/m, W2=M1/ (M0+Mt).Similarly, the food materials priority of the food materials is in being placed into food materials and former food materials When minimum, Fm=Fo, W1=0.The weight that food materials are placed into step S318, which is greater than, is placed into original in the storage room of food materials place Maximum weight in food materials, illustrating to be placed into the maximum food materials of weight in food materials and former food materials is to be placed into food materials, is put at this Enter food materials and the updated former food materials of weight compare, rather than is placed into the power of former food materials before food materials are placed to storage room Weight.Food materials and all former food materials will be placed into and determine weight according to unified benchmark, obtained result is more accurate reasonable.

The current target temperature that the storage room where food materials is placed into step S320 is that weight is maximum in former food materials The corresponding best storage temperature of food materials.The maximum food materials of weight are being placed between food materials are not put into storing in original food materials at this It is determined when room, i.e., the weight of former food materials herein is the weight not updated.In short, the former food in step S316 and step S318 The weight of material is to be placed into food materials to be placed to after storage room, to be placed into the determination based on common of food materials and former food materials Weight；And in step S320 in the corresponding former food materials of current target temperature the maximum food materials of weight best storage temperature, at this The weight of former food materials is unrelated with food materials are placed into based on former food materials.It, can be direct since current target temperature has been set Inquiry obtains.

Fiducial temperature threshold value is provided in step S322, in a kind of preferred embodiment, fiducial temperature threshold value is less than 5 ℃.It should be noted that the difference of current target temperature herein and the best storage temperature for being placed into food materials be defaulted as it is non-negative Number, i.e., when current target temperature is less than the best storage temperature for being placed into food materials, since the difference between the two is negative, difference at this time Value be defaulted as be the two absolute value of the difference.If the difference of current target temperature and the best storage temperature for being placed into food materials is less than Fiducial temperature threshold value illustrates that the best storage temperature for being placed into food materials and the best storage temperature of former food materials are all not much different, can To execute step S324 to step S326, to be placed into the best storage temperature of food materials as between the storing being placed into where food materials The target temperature of room.Step S326 can drive refrigeration system according to target temperature after determining the target temperature of storage room It spends work and meets the storage demand of food materials so that the actual temperature of storage room is consistent with target temperature, guarantee the storage of food materials Effect.

If current target temperature and the difference for the best storage temperature for being placed into food materials are greater than or equal to fiducial temperature threshold value, Illustrate that the best storage temperature for being placed into food materials and the best storage temperature of former food materials all have big difference, step S328 can be executed To step S334, prompt information is exported, it, can be with to remind user to be placed into the storage room where food materials are not suitable for depositing in it It prevents the best storage temperature difference of the variety classes food materials in same storage room excessive, is guaranteeing certain food materials storage effect While be unlikely to seriously affect the storage effect of other food materials, so as to promote the entirety of all kinds of food materials in storage room Effect is stored, the needs of user are met.If but step S332 user selection is placed into food materials and continues to deposit in the storage where it Object compartment illustrates that user determines that the food materials need to deposit in present storage room and guarantee good storage effect, thus The target temperature of the storage room still needs the best storage temperature for being set as being placed into food materials.If user's selection is placed into food Material does not continue to deposit in the storage room where it, illustrates that user will be being placed into food materials by taking in current storage room Out, then current storage room haves no need to change its current target temperature.It should be noted that due to the refrigerator of the present embodiment 100 are provided with multiple storage rooms, and user's taking-up can be put into other storage rooms after being placed into food materials, i.e. change storage is put Enter the storage room of food materials.In some other embodiment, refrigerator 100 may only be provided with single storage room, and user takes out After being placed into food materials, it can choose other refrigeration equipments or other modes stored.

Step S312 to step S334 is the process of priority weights mode, a specific example is introduced below: cold Indoor temperature is typically between 2 DEG C to 10 DEG C between hiding, is preferably 3 DEG C to 8 DEG C.The indoor temperature range of freezer is generally located In -22 DEG C to -14 DEG C, the temperature range of alternating temperature compartment is typically in -15 DEG C to 10 DEG C then than broad.Set refrigerator room Priority be S1, the priority of alternating temperature compartment is S2, and the priority of freezing compartment is S3, and the information that food materials information bank saves is such as Under: fresh meat, F1/S3/-18 DEG C；Fish, F2/S2/-3 DEG C；Chinese cabbage, F3/S2/0 DEG C；Potato, F4/S1/3 DEG C；Orange, F5/S1/ 5℃；Cucumber, F6/S1/8 DEG C, wherein food materials priority F1 is higher than F2, and F2 is higher than F3 ... ..., and so on.

If storage room Central Plains food materials are respectively as follows: potato 1kg and cucumber 0.5kg, being placed into food materials is orange 2kg, pre- If food materials information bank in matching show that the corresponding food materials priority of orange that is placed into is F5, best storage temperature is 5 DEG C, is obtained The food materials priority of former food materials in storage room is taken to be respectively as follows: potato F4 and cucumber F6.It is placed into minimum in food materials and former food materials Food materials priority Fm be F6, be placed into food materials food materials priority Fn be F5, be placed into food materials weight M0 be 2kg, own The weight Mt of former food materials is 1.5kg, then W1=(m-n)/m=(6-5)/6=1/6, W2=M0/ (M0+Mt)=2/ (2+1.5) =4/7, the weight for being placed into food materials orange is W=W1+W2=31/42.

The food materials priority Fo of former food materials potato is F4, and weight M1 is 1kg, then W1=(m-o)/m=(6-4)/6=1/3, W2=M1/ (M0+Mt)=1/ (2+1.5)=2/7, the weight W=W1+W2=13/21 of former food materials potato.

Similarly, the food materials priority Fo of former food materials cucumber is F6, and weight M1 is 0.5kg, then W1=(m-o)/m=(6- 6)/6=0, W2=M1/ (M0+Mt)=0.5/ (2+1.5)=1/7, the weight W=W1+W2=1/7 of former food materials cucumber.

Weight due to being placed into food materials orange is 31/42, and maximum weight is that potato 13/21,31/42 is big in former food materials In 13/21, the weight for being placed into food materials orange is greater than maximum weight in former food materials, and weight of potato is to be placed into food materials at this The weight 13/21 that orange updates after being placed into.Need to obtain the current target temperature of storage room, the current goal in next step Temperature is 3 DEG C of best storage temperature of the maximum potato of weight in former food materials, and the weight of potato is not equivalent to put into orange herein Potato weight after son, but the weight 1 obtained based on potato and cucumber, calculation method is referring to above (due to current Target temperature has been set, and can also directly inquire acquisition).The best storage of 3 DEG C of current target temperature and the orange being placed into The difference that 5 DEG C of temperature is 2 DEG C, if fiducial temperature threshold value is 4 DEG C, since 2 DEG C less than 4 DEG C, determines the target temperature of storage room It is 5 DEG C of best storage temperature of the orange being placed into, and refrigeration system is driven to work according to target temperature.

Step S336 is the process of compartment mode of priority to step S344, and a specific example is introduced below: if The priority of refrigerator room is set as S1, the priority of alternating temperature compartment is S2, and the priority of freezing compartment is S3, food materials information bank The information of preservation is as follows: Chinese cabbage, and F1/S2/0 DEG C；Potato, F2/S1/3 DEG C；Cucumber, F3/S1/8 DEG C.If potato is put into refrigeration Compartment, since the compartment priority of potato is S1, the compartment priority for the refrigerator room that potato is put into also is S1, compartment priority It is identical, the food materials priority and best storage temperature for executing and determining according to the type for being placed into food materials and being placed into food materials can be returned Step S312, and then determine target temperature；If Chinese cabbage is put into freezing compartment, since the compartment priority of Chinese cabbage is S2, The compartment priority for the freezing compartment that Chinese cabbage is put into is S3, and compartment priority is different, then needs to export prompt information, to remind use The storage room of family change storage Chinese cabbage, moves on to alternating temperature compartment by freezing compartment for Chinese cabbage.

Under compartment mode of priority, output prompt information remind user change storage be placed into food materials storage room it Afterwards, regardless of user selects change or do not change to store the storage room for being placed into food materials, the target temperature of the storage room is all Can be constant, it is still current target temperature.Specifically, current if user changes the storage room that storage is placed into food materials Food materials in storage room do not change, and target temperature is constant；If user does not change the storage room that storage is placed into food materials, Illustrate that user wishes that being placed into food materials realizes not common storage effect, such as pears, persimmon etc. should be put into refrigerator room originally Fruit be put into freezing compartment, be in order to realize freeze pears, freeze persimmon effect, it is also desirable to retain the target of current storage room It is temperature-resistant.
