Microcomputer 31 is formed " control device " described in claims, and timer 37 and clock 47 are formed " time set " described in claims.The invention is characterized in that microcomputer 31 carries out following control action.First, the chronometric data of timer 37 or clock 47 timing is recorded in the first storage device 40 and the second storage device 60 on the opportunity of regulation by microcomputer 31.
Then, when there is the phenomenon restored electricity again after temporary power disconnects at least one party of main substrate 30 and auxiliary substrate 50, microcomputer 31 compares with the chronometric data being recorded in the second storage device 60 chronometric data being recorded in the first storage device 40, and covers the chronometric data of little value by the chronometric data of large value.Being covered the chronometric data of the opposing party by a side as comparison other, is the chronometric data of timer 37 timing or the chronometric data of clock 47 timing.Thus, when due to change substrate and a side of main substrate 30 and auxiliary substrate 50 there occurs power supply disconnect and recover phenomenon, can transplant to the substrate not recording chronometric data in the storage device just changed the chronometric data not being replaced the substrate of side, make the substrate being replaced side continue to utilize chronometric data so far.
" chronometric data so far " might not equal " service time " (in this description, " refrigerator is connected to the time of the mains supply do not had a power failure " being defined as " service time ") of refrigerator 1.The chronometric data being recorded in the first storage device 40 or the second storage device 60 can not exceed service time.Being recorded in a side of the large value in the chronometric data of the first storage device 40 and the second storage device 60, is the side that power supply disconnects and the termination that causes data to store is less, therefore can think that described " covering " has meaning close to the service time of reality.
The described control action of the flow chart shown in Fig. 6 ~ Fig. 8 to microcomputer 31 is utilized to be described.In this manual, using the situation of carrying out the action of Fig. 6 as the first embodiment, carry out the situation of action of Fig. 7 as the second embodiment, carry out the situation of action of Fig. 8 as the 3rd embodiment, be described with this.
The feature of the flow process of the first embodiment is " all carrying out Backup Data write when every secondary source disconnects ".
When refrigerator 1 being connected to for the first time mains supply, the plug of the power line of refrigerator 1 temporarily extracts from the socket of mains supply when recovering or in order to change main substrate 30 or auxiliary substrate 50 and then after substrate is changed, plug is inserted the situations such as socket again by the power down mode that produces of mains supply, main substrate 30 and auxiliary substrate 50 both sides become the state of " power supply conducting ".
In step #101, send from the telecommunication circuit 65 of auxiliary substrate 50 to the telecommunication circuit 46 of main substrate 30 chronometric data that second storage device 60 keeps.Communication between telecommunication circuit 65 and telecommunication circuit 46 can be wire communication, also can be radio communication.
In the fig. 6 flow diagram, the chronometric data that the second storage device 60 keeps is referred to as " secondary data ", and the chronometric data that the first storage device 40 keeps is referred to as " master data ".In the following description, the address of " secondary data ", " master data " is also used.
In step #102, check whether the telecommunication circuit 46 of main substrate 30 receives secondary data.If receive secondary data, then advance to step #103.If do not receive secondary data, then return step #102.
When advancing to step #103, microcomputer 31 compares the value of master data and the value of secondary data.If master data is equal with the value of secondary data, or the value of master data is greater than the value of secondary data, then advance to step #105.If the value of secondary data is greater than the value of master data, then advance to step #104.
The value that the value of secondary data is greater than master data means that auxiliary substrate 50 is not replaced and main substrate 30 is replaced.In this case, in step #104, by secondary data cover master data.Thus, continue to utilize chronometric data accumulative so far in the first storage device 40.
The service time of timer 37 pairs of refrigerators 1 carries out timing.Certainly, main substrate 30 and auxiliary substrate 50 in use between in be power supply conducting.The data of timer 37 timing are stored in inside or the RAM33 of microcomputer 31, are recorded in the first storage device 40 and the second storage device 60 on the opportunity of regulation.The opportunity of regulation is " when the event of regulation occurs refrigerator 1 ", and the event of the regulation in the first embodiment be " during to the power supply disconnection of main substrate 30 and auxiliary substrate 50 ".
When usual action, supply the supply voltage (such as 5V) of regulation to microcomputer 31,51.When mains supply has a power failure or the plug of power line of refrigerator 1 is extracted from the socket of mains supply, there is " power supply to main substrate 30 and auxiliary substrate 50 disconnects ", event that namely " power supply disconnection " is such.Now, microcomputer 31 utilizes voltage to reduce test section 34 and detects that supply voltage reduces, and microcomputer 51 utilizes voltage to reduce test section 54 and detects that supply voltage reduces.
Microcomputer 31,51 is set with resetting voltage (such as 3V).When supply voltage reduces because power supply disconnects, utilize the voltage (such as 3.6V) higher than the resetting voltage of microcomputer 31,51 to produce and interrupt (interrupt), before generation microcomputer resets, Backup Data is write the first storage device 40 and the second storage device 60.In flow charts this interruption is denoted as " voltage reduces interruption ".In addition, the such concrete numerical value of 5V, 3V, 3.6V is only illustration, and is not used in and limits invention.
In step #105, check whether main substrate 30 sends voltage and reduce interruption, in step #109, check whether auxiliary substrate 50 sends voltage and reduce interruption.
When confirming the reduction interruption of generation voltage in step #105, advance to step #106.In step #106, the first storage device 40 is carried out to the write of Backup Data.Then step #107 is advanced to.
In step #107, send master data from telecommunication circuit 46 to telecommunication circuit 65.Subsequently, main substrate 30 is standby to wait for the wait state of service restoration and power supply conducting.
Reduce if unconfirmed in step #105 the generation interrupted to voltage, then advance to step #108.In step #108, timer 37 pairs of timing service time.Then, step #105 is returned.
When confirming the reduction interruption of generation voltage in step #109, advance to step #110.In step #110, the second storage device 60 is carried out to the write of Backup Data.Subsequently, auxiliary substrate 50 is standby to wait for the wait state of service restoration and power supply conducting.
Reduce if unconfirmed in step #109 the generation interrupted to voltage, then advance to step #111.In step #111, telecommunication circuit 65 checks whether from telecommunication circuit 46 and receives master data.If confirm the reception of master data, then advance to step #112.If the reception to master data unconfirmed, then return step #109.
In step #112, master data is utilized to cover secondary data.Thus, the first storage device 40 will share the chronometric data of identical value with the second storage device 60.Then step #109 is returned.
Due in step #104 by secondary data cover master data, even if therefore change main substrate 30 also can by new service time data accumulation in data service time so far.Owing to covering secondary data by master data in step #112, even if therefore change auxiliary substrate 50, also data service time with the unconverted value of data service time of main substrate 30 can be kept by auxiliary substrate 50.
Under wait state after step #107, microcomputer 31 is in sleep state.Under wait state after step #110, microcomputer 51 is in sleep state.Supply voltage still can be utilized in a sleep state to reduce even if microcomputer 31,51 has and produce interruption, and from the function that sleep state recovers.Therefore, when microcomputer 31,51 again starts after voltage reduction being detected, the backup of data can be carried out.
As mentioned above, whenever producing voltage because power supply disconnects and reducing interruption, all the first storage device 40 and the second storage device 60 are carried out to the write of Backup Data, therefore the first storage device 40 and the second storage device 60 reliably keep the chronometric data of service time all the time.When recovering power supply conducting, as long as read the data of the first storage device 40 and the second storage device 60, just service time can be added up and timing.
According to the flow chart of Fig. 6, when once more becoming power supply conducting after main substrate 30 and auxiliary substrate 50 become power supply disconnection, the chronometric data being recorded in the second storage device 60 is sent to main substrate 30, compare the chronometric data of the first storage device 40 and the chronometric data of the second storage device 60 in main substrate 30 side, select a side of large value.Also can change this role-sharing, carry out the comparison and selection of the chronometric data of the first storage device 40 and the chronometric data of the second storage device 60 in auxiliary substrate 50 side.
< second embodiment >
In the first embodiment, regulation opportunity that the data of timer 37 timing are recorded in the first storage device 40 and the second storage device 60 is " when the event of regulation occurs refrigerator 1 ", and the event of this regulation be " during to the power supply disconnection of main substrate 30 and auxiliary substrate 50 ".In this second embodiment, the event beyond this situation also becomes regulation opportunity.
In this second embodiment, control action is carried out according to the flow chart of Fig. 7.In the flow chart of figure 7, delete the step #107 existed in the fig. 6 flow diagram, new additional step #120 ~ #124.The feature of the flow process of the second embodiment is " all transmitting when all carrying out Backup Data write, each generation event when every secondary source disconnects ".Below, the difference for the flow chart with Fig. 6 is described.

In 3rd embodiment, when disconnecting to the power supply of refrigerator 1, not to storage device writing backup data or the chronometric data of receiving and dispatching service time, therefore compared with first, second embodiment, further mitigate the burden of microcomputer when power supply stops.Therefore, the capacitor for maintaining supply voltage when making power supply stop realizes low capacity further, can cut down cost further.However, the data still reliably can carrying out the first storage device 40 and the second storage device 60 keep.
In the third embodiment, the record of the chronometric data to the first storage device 40 and the second storage device 60 is all carried out when each event occurs.Compared with first, second embodiment, the write number of times of the first storage device 40 and the second storage device 60 is increased, but and do not mean that and write at any time, therefore there will not be large problem.
In the third embodiment, when auxiliary substrate 50 receives the chronometric data of service time from main substrate 30, these data can not be recorded in RAM53 by microcomputer 51, but are directly recorded in the second storage device 60.
Microcomputer 51 can also be saved from auxiliary substrate 50, the interface of " display (+operation) " combines EEPROM controller to replace microcomputer 51.Thus, the cost of auxiliary substrate 50 can be reduced.
Other > of <
In second, third embodiment, following situation can be added to " event of regulation ".
When a. communicating between main substrate 30 and auxiliary substrate 50
B. door 12 is opened when display element 64 is lighted
When c. obtaining information from the sensor set by auxiliary substrate 50
Under the microcomputer 51 of auxiliary substrate 50 has the electricity saving function situations such as sleep pattern, if record service time when main substrate 30 communicates with auxiliary substrate 50 at the second storage device 60, then without the need to the microcomputer 51 of auxiliary substrate 50 being recovered from sleep pattern just to recording service time at the second storage device 60, thus can economize on electricity.
Although describe as common in the first embodiment ~ the 3rd embodiment, when but namely the event being limited to regulation occurs being rewritten for the data record of the first storage device 40 and the second storage device 60, therefore number of rewrites is less, even if storage device uses EEPROM, during till also can significantly extending the boundary reaching number of rewrites.
" opportunity of regulation " not only comprises " when there is the event of regulation ", can also comprise " regulation moment ".Can be such as " clock 47 point at 0 in the morning when " etc.By data service time of timer 37 timing are recorded in the first storage device 40 and the second storage device 60 in the regulation moment, the deviation accumulation value between the service time of reality and the service time of record can be managed as within certain value.Such as, if be set as " every 24 hours ", then the error management of the service time when power supply of refrigerator 1 can be disconnected is maximum within 24 hours.
The data of the service time of timer 37 timing are preferably in due course, such as service time informs user when reaching setting.As notifying device, loudspeaker 22 can be used.Or also liquid crystal panel can be set at display part 18, be notified by liquid crystal panel.
Opportunity of notice can for user after exceeding setting service time opens door for the first time and when making door switch 43 action.Thereby, it is possible to the situation starting notice and so on when avoiding user to go out occurs.
The notice of service time such as can be set as often notifying through 1 year.
Also can according to the content change making notice through New Year number.Such as, the message of " thanking to the use of 1 year " can formed before 10 years, and if then exported the message of prompting replacing refrigerator 1 more than 10 years.Thus, user can be allowed to recognize the lifespan of refrigerator 1, experience cordial feeling, and can cause because Long-Time Service produces penalty or fault before user awares inconvenience, making user recognize should change.
Can not notify user based on the data of the service time of timer 37 timing, but based on the time data of clock 47, user be notified.Such as can notify the elapsed time from using and starting.For this reason, user is determined carry out as use Start Date of refrigerator 1 and time the date and time information that records, be recorded in the first storage device 40 and the second storage device 60 both sides.Current date and time shown by clock 47 deducts and uses Start Date and time to draw elapsed time from using and starting.
Such as when being when using Start Date and time by day entry in January 1, even if the power supply waiting because having a power failure and disconnect refrigerator 1, still can, at notice lifespan on annual January 1, user be made to produce consciousness as the birthday.The opportunity of notice can be when after lifespan exceeds setting, user opens door for the first time and makes door switch 43 carry out action.Thereby, it is possible to the situation starting notice and so on when avoiding user to go out occurs.
Particular day can be set as the commemoration day by user, and the same day, when being opened the door of refrigerator 1 by user for the first time or operating, notifies that the same day is the commemoration day set.
When by clock 47 pairs of timing service time, need the moment of aiming at clock 47.In the situation such as power supply disconnection had a power failure or make refrigerator 1 to repair, if power supply user's misalignment time after conducting again, then cannot carry out the notice of service time exactly.Under these circumstances, utilize timer 37 pair service time timing different from clock 47, therefore, it is possible to the cumulative data of service time based on timer 37 timing, notify lifespan to user.
When refrigerator 1 has these two kinds of data service time service time of service time of clock 47 timing and timer 37 timing, there is the possibility notifying twice identical message (such as " use after starting through 1 year ") to user.In this case, can be set as only notifying when the service time of one party first reaches setting, even and if reach setting the service time of the opposing party and also do not notify.
By carrying out described setting, such as implement while user brings into use refrigerator 1 clock 47 pair time, the service time that can not surmount timer 37 timing service time since the use that the time information of origin self-clock 47 calculates starts.Therefore, it is possible to utilize the function of clock 47 to notify service time accurately to user.Do not carry out while user brings into use refrigerator 1 clock 47 pair time but when to carry out afterwards pair, because the service time of timer 37 timing first reaches setting, content of announcement is therefore prevented to differ greatly with actual service time and cause user to feel inharmonious.
One side or both sides in timer 37 and clock 47 can be arranged at auxiliary substrate 50 side.
Above embodiments of the present invention are illustrated, but scope of the present invention is not limited thereto.Only otherwise depart from the purport of invention, can various change be carried out implement.
Industrial applicibility
The present invention can be widely used in refrigerator.
