Also, as shown in Figure 1, being provided with the door opening and closing sensor of the open and-shut mode of detection door on each door in refrigerator 1 9.Specifically, being provided with an opening and closing sensor 9a on left-hand door 3a, an opening and closing sensor 9b is provided on right door 3b, in vegetables It is provided with an opening and closing sensor 9c on the door 4a of room, an opening and closing sensor 9d is provided on ice-making compartment door 5a, in small refrigerating chamber door It is provided with an opening and closing sensor 9e on 6a, an opening and closing sensor 9f is provided on big refrigerating chamber door 7a.These opening and closing sensing Device 9 is equivalent to opening and closing test section.

Also, refrigerator 1 is provided with multiple temperature sensors 10 of detection storage compartment temperature in storeroom.Specifically, It is provided with temperature sensor 10a in refrigerating chamber 3, temperature sensor 10b is provided in vegetable compartment 4, is arranged in small freezing chamber 6 There is temperature sensor 10c, is provided with temperature sensor 10d in big freezing chamber 7.

Also, refrigerator 1 is in positive side --- someone's detection sensor 11 is set before such as left-hand door 3a.People, which detects, to be passed Sensor 11 is the device for being known as so-called human body sensing sensor, by well-known infrared sensor, electrostatic transducer, ultrasound Wave sensor, optical sensor or photographic device etc. are constituted.People's detection sensor 11 is used for, and it is attached to be present in refrigerator 1 by detection Closely --- the front of especially refrigerator 1 is considered the people of the position using refrigerator 1, makes for example, by lighting operation panel 8 Operation is easy the control waited.

The refrigerator 1 is controlled by control unit 12.Control unit 12 is connect with above-mentioned various sensors, according to their testing result Entire refrigerator 1 is controlled Deng by making refrigerating cycle operation (not shown) etc..

Also, although details are aftermentioned, and control unit 12 is associated with present embodiment, and setting indicates to be opened and closed sensor 9 in door Detect that a possibility that being at the time of opening and closing maximum a possibility that expression is in time going by simultaneously reduces Family's index, executing will be according to from the current time for detecting that the time begun to pass through at the time of opening and closing finds out via communication unit 13 Index of being in be supplied to the processing of external device (ED).

Also, control unit 12 rises be opened and closed according to 1 door required for opening/closing time, the opening and closing of scheduled period inside door number with And at least one condition in the type of the door of opening and closing, thus it is speculated that after door opening and closing user take and it is expected that the action of action push away The effect in survey portion.

Communication unit 13 is the equipment of the wireless modes such as wired mode or WiFi, via network and the various letters of communication with external apparatus Breath.As network, it is contemplated that for the internet, common line network of LAN in via family.Also, as external device (ED), It is envisioned for for example postal dealer, dispensing dealer dispenses or dispense again the server used, portable terminal, long-range place Household, server, the portable terminal of medical care institutions etc..And, it may also be said to external device (ED) connects from such refrigerator 1 It is received in a situation, situation of being in is constituted and system is provided.

Illustrate the effect of above-mentioned refrigerator 1 below.

In recent years, it in order to reduce the waste of dispatching and in order to improve the convenience of user, proposes according to household electric The behaviour in service of device, situation of being in using electric power judgement, the system informed to dispensing dealer.

But even if such as household electrical appliance refrigerator 1 user not in case, refrigerating cycle, system sometimes Ice production apparatus also works, as other household electrical appliance washing machine also due to reservation operation etc. and even if user not the case where Under also work sometimes.Also, in recent years, also popularized from the technology of the household electrical appliance of outgoing destination remote control operation family, Judge that the situation of being in becomes difficult according to electricity usage state.

In this case, it is used to detect sensor of being in of people of family etc. and can accurately judge if setting is multiple Family's situation, but be not for safety purposes and to be difficult the dispatching for being considered to occur daily and sensor of being in is set, existing makes The burden sense of user becomes larger such problems.

Door is opened and closed in the article etc. that culinary art, taking-up beverage or storage are bought and is used by refrigerator 1.Result, it is believed that If user at home if refrigerator 1 use a possibility that it is high.Also, refrigerator is then set if it is general family 1 the case where, is more, and is the state of a direct power supply.It is therefore contemplated that refrigerator 1 is the household electric suitable for the situation that judges to be in Device.

Therefore, using the refrigerator 1 for thinking the setting 1 in each family in present embodiment, by described below a variety of Various ways combination is determined the situation of being in and is supplied to external device (ED) by mode.

(1) the 1st mode

The method referring to figs. 1 to Fig. 3 to use refrigerator 1 judge be in situation when elemental motion be illustrated.

Refrigerator 1 determines the index of being in for a possibility that prompt user is according to the open and-shut mode of certain fan door.This implementation In mode, use as index of being in from the 0% of minimum value to the rate of being in elapsed the 100% of maximum value.Rate of being in exists User is maximum value in the case where being in really, is not really in case minimum value in user.

The rate of being in is set in this way: as maximum value at the time of detecting opening and closing by door opening and closing sensor 9, as the time passes through Cross value reduction.Therefore, refrigerator 1 can be according to from detecting that the time begun to pass through at the time of opening and closing finds out current time It is in rate.But index of being in can both use other numbers without the necessity that must be indicated with percentage as the rate of being in Be worth range, can also use at the time of detecting opening as minimum value, as time goes by value become larger for example not in rate. I.e., if it is possible to if judging a possibility that user is in and variation a possibility that being in as time goes by, then be in Index can suitably use various forms of numerical value, index.

Specifically, as shown in figure 3, the rate of being in is set as maximum value if detecting certain fan door opening and closing at the moment (t1) 100%.This is because user is really in front of refrigerator 1, i.e., the reason being in really in the case where certain fan door opening and closing.

Then, rate of being in is with time going by with the reduction of scheduled slip.That is, index of being in is according to progress door opening and closing Afterwards by the time and change.At this point, as an example of slip, but can also use and for example become most in 3 hours from maximum value The ratio of small value.Also, slip can both predefine, and person's setting not can be used yet.In addition, being used as index of being in Not in the case where rate, index of being in rises.

The rate of being in for being set as maximum value is reduced with time going by, detects a feelings for opening and closing at such as moment (t2) Under condition, after resetting as maximum value, with being reduced by the time since moment (t2).Also, it is repeated for example In the case where detecting opening and closing at the moment (t3), the rate of being in is reset as after maximum value, with the warp since moment (t3) It spends the time and reduces down.In addition, the rate of being in reaches minimum value if not detecting an opening and closing always.

Also, refrigerator 1 finds out the rate of being according to from the time begun to pass through at the time of the rate of being in is set as maximum value, according to The situation of being in of the rate of being in or the information comprising can determine the rate of being in is supplied to external device (ED) according to needs.In this case, Refrigerator 1 is not necessarily required to find out the rate of being in always, can also using storage will the rate of being in be set as maximum value at the time of, find out and need Want the structure of the rate of being at moment.The generations such as the pre- settled date of dispatching cargo can be considered at the time of needs and be supplied to external device (ED) At the time of needs, or exist come the people on one's own side confirmation safety whether the case where etc. from external device (ED) request at the time of.

Also, due to the viewpoint from prevention, privacy, it is desirable to be able to which whether setting provides the situation of being in, provides The date and time for situation of being in, as provide destination external device (ED) registration, could to the request from external device (ED) Carry out response etc..The date and time for providing situation of being in, which can be considered, for example to be dispensed the pre- settled date of cargo, has entrusted and dispense again When dispense day etc. again.Also, it can also make that the situation of being in could be provided and whether to perform and obtain the processing gearing for the rate of being in Get up, realizes and save electric energy.

(2) the 2nd modes

The method illustrates opening/closing time required for being opened and closed according to 1 door referring to Fig. 4 to change the slip for the rate of being in Example.

Refrigerator 1 carries out being removed and placed into for article as described above, but is difficult to user after the door opening and closing for resting in refrigerator 1 How to be acted.But the purpose as shutter door, it is contemplated that for example taking out food materials to cook, and storage purchase The taking-up food of the not subsidiary culinary art such as the article, the taking-up beverage that enter.

At this point it is possible to think, different according to purpose, it is respectively different that 1 door is opened and closed required opening/closing time.Such as carry out It can consider that the open time is long when product are bought in storage after shopping.Also, similarly think out when being cooked and taking out food materials The time put is long.On the other hand, subsidiary culinary art when, due to taking out beverage, slightly preference, it can be considered that when open Between shorten.

Also, the case where buying product if it is storage can recognize due to may be considered after user just goes home A possibility that be in after shutter door height.Also, the case where taking out food materials to cook, it is also assumed that in order to cook and A possibility that family, is high.In other words, in the case where door opening/closing time is long, it is believed that later not a possibility that it is low.

On the other hand, it is believed that judgement is not more difficult when subsidiary culinary art, but can not necessarily say a possibility that being in ratio It is taken out when product are bought in storage and in order to cook high when food materials.

In this way, the purpose by speculating user from door opening/closing time, it is believed that can speculate and be envisioned for hereafter using The action that person takes.And it is believed that the reduction for making the rate of being in by the action taken according to the purpose of shutter door, user Rate variation, can be improved the precision for the rate of being in.

Therefore, as " state of door " display in Fig. 4, the open and-shut mode of door is door open state at moment (t10), It is door blocking at moment (t11).In this case, the time of door opening and closing is t11-t10.Also, it is opened from the moment (t11) Beginning rate of being in is reduced with slip.In addition, the rate of being in can also using at the time of detecting open (t10) be set as maximum Value, until (t11) maintains the structure of maximum value at the time of detecting locking.

Also, become an open state at the moment (t12), in the case that the moment (t13) becomes blocking, door opening and closing Time be t13-t12.At this point, making the rate of being in since moment (t13) if (t11-t10) > (t13-t12) Slip of the slip ratio since moment (t11) it is big.In other words, the longer slip for making the rate of being in of opening/closing time is smaller.

User has used as a result, uses form to be added in the operation for the rate of being in when refrigerator 1, can find out and more meet Actual rate of being in.Alternatively, it is also possible to using preset as benchmark opening/closing time and the opening/closing time become benchmark Slip, it is longer or short than the opening/closing time for becoming benchmark according to actual opening/closing time, and according to long or how much short To change the structure of slip.

(3) the 3rd modes

The method referring to Fig. 5 to according to during predetermined judgement inside door be opened and closed number or according in multiple leaf door which Fan door opening and closing is illustrated to change the example of the slip for the rate of being in.

In the case where general refrigerator 1, it is believed that can speculate the food being stored in each storeroom to a certain extent The type of material and other items.For example, being speculated as storing the dish etc. after beverage and condiment etc., culinary art in refrigerating chamber 3, in vegetable compartment 4 Vegetables are stored, preferences such as storage shelf-life long frozen food, ice cream etc. in big freezing chamber 7.

Also, after for example being done shopping, it is believed that in order to store various food, each door opening/closing time fifty-fifty becomes It is long, while multiple leaf door is opened and closed in order to store various food respectively.

Also, when cooking, it is contemplated that increase opening and closing number because of multiple material is taken out from each storage device, but it is each Average elongated during door opening and closing, not equal to the dish because of production is different, without using freezing food materials etc., the type of the door of opening and closing is inclined Quite a possibility that, is higher.

Also, it may be considered the reason using ice when being opened and closed ice-making compartment door 5a, but in the right door 3b of such as refrigerating chamber 3 After opening in the short time in the case where open ice-making compartment door 5a, it is believed that be on the rocks into beverage.

In this way it can be considered that the purpose of shutter door can not only be speculated by above-mentioned opening/closing time, and can be by door The number of opening and closing speculates with which fan door has been opened and closed.It, also can be from even if the time of 1 door opening and closing is identical and it is possible to think Where opening and closing number, opening and closing fan door to speculate the purpose of shutter door.

In this way it can be considered that the purpose by speculating user from door opening/closing time, can speculate and be envisioned for hereafter using Person takes action.And it is possible to think, the reduction for the rate of being in is made by the action taken according to the purpose of shutter door, user Rate variation, can be improved the precision for the rate of being in.

Therefore, the scheduled period that " P " is expressed as in Fig. 5 is set first.The scheduled period is to be initially detected an opening and closing Moment --- (t20) is starting point at the time of such as Fig. 5, is continueed to hereafter by the preset time.In addition, scheduled period energy Enough it is set as such as or so a few minutes.

Also, in the case where detecting the opening and closing of multiple door within the scheduled period (P) from the moment (t20) to moment (t21), Because it is considered that being to store the situation of food materials after shopping or in order to be cooked and the situation of shutter door, therefore can speculate Hereafter the action of user is to be in.Such case also includes the situation that multiple leaf door is opened and closed by each.

On the other hand, the feelings of primary door opening and closing are detected within the scheduled period (P) from the moment (t22) to moment (t23) Under condition, can speculate with after above-mentioned shopping, culinary art when compared with, the action of user is relatively low a possibility that being in.

Therefore, the slip for making the slip of moment (t23) later rate of being in later than the above-mentioned moment (t21) is big.It changes Yan Zhi, the opening and closing number in the scheduled period is more, keeps the slip for the rate of being in smaller.

User has used the operation for using form to be added to the rate of being in when refrigerator 1 as a result, can find out and more meet reality The rate of being on border.Alternatively, it is also possible to become benchmark as the opening and closing number of benchmark and the opening and closing number using presetting Slip, according to actual opening and closing number than becoming the opening and closing of benchmark often or few structure to change slip.

(4) the 4th modes

Become in the method referring to temperature change of the Fig. 6 to the storeroom detected after being opened and closed according to door by temperature sensor 10 The example of the slip for rate of being more in is illustrated.The temperature of storeroom is known as " the temperature inside the box " below.

In the case where food materials bought and other items are for example stored into refrigerating chamber 3, freezing chamber, due to storage temperature ratio The high article of article in the case is stored before this, therefore, it is considered that the temperature inside the box has and rises to a certain degree after door opening and closing.Also, small In the case where the cooked food of 6 rapid freezing of freezing chamber, temperature is substantially increased sometimes.

On the other hand, in order to cook etc. and take out food materials, due in case food materials it is temperature-resistant, because This thinks that the temperature inside the box will not be widely varied.But due to consideration that import outside air because of shutter door, temperature slightly on Rise, therefore it is contemplated herein, that after door locking through it is too short temporarily between at the time of, such as the temperature inside the box at the time of by 5 minutes or so.

In this way it can be considered that the temperature change of the storeroom detected after being opened and closed according to door by temperature sensor 10, it can After for example, if how the temperature inside the box does not rise, before being culinary art, if a little rise being shopping, if substantial increase It is to speculate the purpose of shutter door and the action that hereafter user takes in this way after culinary art.

Therefore, a variation of the temperature inside the box after at the time of detecting opening and closing as shown in FIG. 6.In addition, not having Must in temporal sequence in detection case temperature change needs, can using by the time of detecting locking the temperature inside the box and The temperature inside the box at the time of have passed through the predetermined time after door locking finds out the structure of temperature change.

Specifically, in the case where detecting opening and closing at the moment (t30), by the moment (t30) the temperature inside the box and have passed through The temperature inside the box of (t31) finds out temperature difference or rate of temperature change at the time of predetermined time, sets slip according to the result, makes Family's rate is reduced.

Also, in the case where detecting opening and closing at the moment (t32), by the moment (t32) the temperature inside the box and have passed through pre- The temperature inside the box of (t33) finds out temperature difference or rate of temperature change at the time of fixing time, and sets slip according to the result, makes to be in Rate is reduced.In this case, if the moment (t33) it is later temperature change it is later than the moment (t31) temperature change it is big, sentence Food is stored after being set to such as shopping, makes slip of the slip ratio since moment (t31) since moment (t33) It is small.

User has used the operation for using form to be added to the rate of being in when refrigerator 1 as a result, can find out and more meet reality The rate of being on border.In addition, also can be using the reduction for presetting temperature difference or rate of temperature change and the benchmark as benchmark Rate, according to actual temperature difference, rate of temperature change is bigger than benchmark or the small structure to change slip.Also, it can also adopt The structure of individual benchmark is respectively set with the storeroom different with the such temperature range of big freezing chamber 7 to refrigerating chamber 3.

(5) the 5th modes

It is said in the method referring to example of the Fig. 7 to the slip that each predetermined period changes rate of being in It is bright.

General daily life, it is believed that get up in the morning has breakfast, and because work etc. is outgoing between daytime, goes home to have supper at dusk, so The situation slept afterwards.Therefore, it can think that the rate of being in that user is in can carry out a degree of push away according to the period It surveys.

The period for being envisioned for carrying out the preparation and intake of breakfast is known as early meal section below, the outgoing time will be envisioned for Section be known as daytime between section, by be envisioned for carry out supper preparation and intake period be known as supper section, by be envisioned for sleep when Between section be known as night section.In addition, type and length can suitably change or by user as an example of the differentiation only of period Setting.

Therefore, as shown in FIG. 7, (t40) detection door is opened and closed and then without detecting opening and closing at the time of such as early meal section The slip for being transitioned between daytime section between in the case where section, making daytime is bigger than the slip of early meal section.It is high a possibility that outgoing as a result, Daytime between section can find out and more meet actual rate of being in.

Alternatively, the feelings that (t41) has detected an opening and closing, is then transitioned into night section without detecting opening and closing at the time of supper section Under condition, keep the slip of night section smaller than the slip of supper section.Night high a possibility that sleep etc. is in section energy as a result, It enough avoids and practical situation opposite, the rate of being in becomes minimum value.

The operation that the rate of being in is added to using form when user is using refrigerator 1 as a result, can find out and more meet reality Rate of being in.Alternatively, it is also possible to using preset the slip as benchmark, according to the period can be bigger or small than benchmark The structure that ground change or user can set.

(6) the 6th modes

Referring to Fig. 8 and Fig. 9 to according to the testing result of people's detection sensor 11, carry out to operation panel 8 in the method The example of the slip for rate of being in is changed in operation, and example corresponding with its subsidiary situation is illustrated.

Someone's detection sensor 11 is set as described above in refrigerator 1.Therefore, by user's detection sensor 11, even if Without the such operation directly to refrigerator 1 of door opening and closing, it is also able to detect that someone near refrigerator 1 sometimes.

Therefore, as shown in FIG. 8, for example at the time of becoming having can't detect people after the moment (t50) detects people, The rate of being in can be set as maximum value.In this case, rate of being in reduces as time goes by, if for example when Carving after (t51) detects people becomes to have can't detect people, then after being set as maximum value again, subtracts with time going by It is small.

In this way, also can be with the detection knot of the above-mentioned open and-shut mode according to door according to the testing result of people's detection sensor 11 It is same when fruit, the rate of being in suitably is set as maximum value.

Also, refrigerator 1 has outgoing button 81a as described above.Outgoing button 81a is that the situation that user goes out is led to Know to the device of refrigerator 1, by as the trigger for being for example transitioned into battery saving mode come using.Also, operate it is outgoing by In the case where button 81a, can be determined with relatively high accuracy rate hereafter user action be it is outgoing, that is, stay out.

Therefore, in the case where moment (t52) for example shown in Fig. 8 operates outgoing button 81a, make the rate of being in immediately Minimum value.Thereby, it is possible to make the suitable value of the value for the rate of being in.In this case, it is believed that after operating outgoing button 81a A few minutes clock time in user be in, still, since user wishes outgoing at the time of operating outgoing button 81a, because This can be prevented from having carried out connection dispensed again etc. when wanting outgoing and cannot gone out by the way that the rate of being in is become minimum value immediately Situation etc., it is believed that improve the convenience of user.

And it is possible to using during after operating outgoing button 81a by scheduled stand-by time, regardless of opening for door How the rate of being in all is maintained the structure of minimum value by the testing result of closed state and the testing result of people's detection sensor 11.By This, can prevent from vainly improving rate of being in the case where clearly outgoing.

It is inferior the case where operating outgoing button 81a and have passed through standby period, when operate outgoing button 81a with After when detecting certain fan door opening and closing or people's detection sensor 11 is when detecting people, rate maximum value of being in can be made.

Even if also the rate of being in can be made to become to meet reality in the case where user forgets to release outgoing button 81a as a result, The value on border.At this point, the outgoing display unit 82a lighted because operating outgoing button 81a can be made to extinguish.

But the case where from according to the testing result of the open and-shut mode of door, is different, in the inspection according to people's detection sensor 11 In the case where surveying result, the supposition of the action of user hereafter is difficult.Therefore, as shown in FIG. 9, if it is for example when It carves (t60) and detects an opening and closing, the case where moment (t61) people detection sensor 11 detects people, make since moment (t61) Rate of being in be in rate of the slip ratio since moment (t60) slip it is big.

In this way, detecting biography with from people by the slip in the rate of being in since at the time of detecting the open and-shut mode of door Sensor 11, which can't detect, is arranged difference between the slip started at the time of people, that is, passes through the action for making to be easy to speculate user Open and-shut mode detection when rate of being in people detection of the value than being difficult to speculate the action of user when rate of being in value it is big, energy Enough values for more suitably setting rate of being in can be improved precision when judgement is in.

The refrigerator 1 crossed from the description above, following effect can be obtained.

The refrigerator 1 of embodiment has: the communication unit 13 communicated between external device (ED)；Detection opening and closing storeroom The opening and closing test section of the open and-shut mode of door；And setting is in index and execute will be according to from detecting door via communication unit 13 The time that have passed through from the time of opening and closing and the index of being at current time found out are supplied to the control of the processing of external device (ED) Portion 12, it is above-mentioned to be in index to indicate that a possibility that being at the time of detecting opening and closing by opening and closing test section is maximum, simultaneously Indicate the index reduced a possibility that being in as time goes by.

Thereby, it is possible to unrelated with the electricity usage state that becomes difficult of the judgement situation of being in and user will not be made to feel To cost burden sense high-precision judges situation of being in, and the situation of being in can be supplied to external device (ED).

Also, accurately acquire as described above be in index can only voucher platform refrigerator 1 and grasp, thus also clever It is living to be applied to power-saving control, but by being supplied to external device (ED), can be improved the convenience or flexible Application of dispensing dealer In the guard feature of People.

Also, refrigerator 1 has an action estimating unit, opening/closing time required for this action estimating unit is opened and closed according to 1 door, pre- The type of the door of inside door is opened and closed between periodically number, opening and closing and detect at least one condition in period of opening and closing, Speculate the action that user takes after door is opened and closed, the variable quantity for index of being in, embodiment are changed according to the estimation result It says as the slip for rate of being in.Thereby, it is possible to carry out the judgement of being in of the action based on user, carry out meeting it is actual The judgement of family, can be improved the precision of judgement.

Also, opening/closing time required for refrigerator 1 is opened and closed according to 1 door changes the variable quantity for index of being in, embodiment In for be the slip of rate of being in.Thereby, it is possible to more precisely speculate the action of user, the situation of being in can be improved Precision.

Also, opening/closing time required for refrigerator 1 is opened and closed according to 1 door, opening/closing time is longer to be made to be in the variation of index Amount --- it is smaller for the slip for rate of being in embodiment.Thereby, it is possible to more precisely speculate the action of user, It can be improved the precision for the situation of being in.

Also, refrigerator 1 changes the variation for index of being according to the door opening and closing number during predetermined judgement Amount --- it is the slip for rate of being in embodiment.It, can thereby, it is possible to more precisely speculate the action of user Improve the precision for situation of being in.

Also, refrigerator 1 changes the variable quantity for index of being according to which fan door opening and closing --- it is to be in embodiment The slip of rate.Thereby, it is possible to more precisely speculate the action of user, the precision for the situation of being in can be improved.

Also, refrigerator 1 has the temperature sensor 10 of the temperature of detection storeroom, temperature sensor 10 after being opened and closed according to door The temperature change of the storeroom detected changes the variable quantity for index of being in --- and it is the reduction for rate of being in embodiment Rate.Thereby, it is possible to more precisely speculate the action of user, the precision for the situation of being in can be improved.

Also, refrigerator 1 changes the variable quantity for index of being in per the predetermined period --- be in embodiment The slip for rate of being in.Thereby, it is possible to follow the judgement of the action of user, the precision for the situation of being in can be improved.

Also, refrigerator 1 has people's detection sensor 11 of the movement of detection people, detects by people's detection sensor 11 People, the index that will be at the time of hereafter become can't detect are set as maximum.As a result, with detection door open and-shut mode when it is same Sample, can be unrelated with the electricity usage state that becomes difficult of the judgement situation of being in and will not make user feel the negative of cost Load sense ground high-precision judges situation of being in, and the situation of being in can be supplied to external device (ED).

Also, refrigerator 1 makes variable quantity --- the embodiment of the index of being in since at the time of becoming can't detect people In for be in rate slip than the index of being in since at the time of detecting the open and-shut mode of door variable quantity --- It is big for the slip for rate of being in embodiment.Thereby, it is possible to so that the action for speculating user is readily detected opening and closing shape Index of being in when the detection people of action hardly possible of the index of being in than speculating user when state is big, can set and more suitably be in Index can be improved precision when judgement is in.

Also, refrigerator 1 have setting user not outgoing button 81a, when operating outgoing button 81a, make to be in Index --- it is rate minimum of being in embodiment.Thereby, it is possible to suitably set index of being in.

Also, when refrigerator 1 detects certain fan door opening and closing after operating outgoing button 81a, make index of being in --- it is real It applies in mode as rate maximum of being in.As a result, even if having forgotten release outgoing button 81a in the case where can be automatically Index of being in is suitably set, therefore can be improved the accuracy for the rate of being in.

Although separately illustrating each mode in embodiment, each mode can be combined.For example, being capable of basis Door opening/closing time, the number of door opening and closing, opening and closing door type and detect 2 or more items in period of opening and closing Part changes the change rate for index of being in.In this case, it may be considered that opening/closing time is longer and is opened and closed that number to be made to be in The change rate of rate is smaller etc..Also, even if the open hour, opening and closing number it is identical, it is also contemplated that making the change rate ratio of supper section The change rate of early meal section is small.

Although, can also be using 1 using the structure that 1 temperature sensor 10 is arranged in each storeroom in embodiment Multiple temperature sensors 10, or refrigerating chamber 3 and vegetable compartment 4 to the storeroom as Leng KURA temperature range are arranged in a storeroom 1 temperature sensor 10, or the ice-making compartment 5 to the storeroom as cryogenic temperature range, small freezing chamber 6 and big freezing are set The structure of 1 temperature sensor 10 is arranged in room 7.

Although being had been illustrated in embodiment as index of being in using rate of being in, from being opened at the time of being set as maximum value Begin the structure of reduction as time goes by, but user is in really at the time of due to being set as maximum value, can also be with Using maximum value is maintained in the predetermined time since at the time of being set as maximum value, pass through and the knot of reduction then as the time Structure.

It is continuously reduced as index is in using rate of being in, as time goes by although being had been illustrated in embodiment Structure, but can also be using every structure by predetermined time reduction step by step.

Although describing the example for changing the change rate for index of being in embodiment, it can also use and be in index not It is exhausted when changing change rate --- reduce ratio when perhaps increasing but change variable quantity --- i.e. reduction or increasing To the structure of value.Also, it is also possible to for example, by using dividing into being in for such as high, medium and low 3 class a possibility that being in The structure of index.

In this case, the upper limit such as maximum value and the lower limit such as minimum value of index if regulation is in, if become More variable quantity, then change rate also changes.Therefore, the structure for changing the change rate for index of being in actually includes change variable quantity Structure.Also, using divide into multiple class be in index in the case where, due to switching from door locking begin to pass through Time, door the condition of the index of being in such as opening and closing number be equivalent to above-mentioned change rate, variable quantity, therefore also comprising change for example The structure of condition in switching from high to.

Above embodiment is intended only as example proposition, and the range of non-limiting invention.These new embodiments can Implement in the form of other are various, is able to carry out various omission, substitution, and alteration without departing from the spirit of the invention.This implementation Mode and its deformation are included in the range and objective of invention, while included in the invention of the scope of the claims record and its Deng range in.
