Description

  The present invention relates to a refrigerator suitable for a home appliance service system using a communication network such as the Internet and a communication system using the refrigerator.

  In general, there is a system in which data is exchanged with home appliances via a communication network such as the Internet to improve convenience of the home appliances. For example, a refrigerator that connects a refrigerator to the Internet and transmits the content of the failure to a service provider to enable accurate failure repair has been proposed (for example, see Patent Document 1).

  The devices used in such a system are not limited to refrigerators, and other home appliances are often the same. Such devices are called so-called Internet home appliances, and in recent years, with the development of communication infrastructure and the evolution of mobile terminals, they have become more and more widespread. Expected to be equipped.

JP 2002-295939 A

  As home appliances are being digitized as described above, white goods are generally used in everyday life regardless of age or gender, so the ease of use is very important. Is done. That is, as long as a single refrigerator is only connected to the Internet, there is no problem in usability and the service can be fully enjoyed. However, when data conversion of home appliances spreads and multiple home appliances are connected to the Internet and become a service target, what kind of solid the target device shows in bidirectional exchange of device data, such as children and the elderly Is difficult to understand and difficult to use. In addition, for example, when two refrigerators are held in the home, a problem that the temperature inside the refrigerator is set incorrectly can be predicted.

  In addition, security measures are also a major issue. In other words, considering the reality that even a system such as an administrative organization protected by a very high level of security can suffer cyber damage, there is a good chance that home appliance data will cause damage to home equipment and data. . For example, there is a risk that device data will be leaked and a risk that the device will be controlled without permission. Although measures to protect by various security technologies are socially taken, there is a possibility that the basic function of the product may be impaired especially when the setting is changed without permission.

  Therefore, the present inventors provide an RFID (Radio Frequency IDentification) tag in the refrigerator main body, and by bringing the portable terminal close to the RFID tag, the data is exchanged between the refrigerator main body and the portable terminal, via the portable terminal. We have already proposed a refrigerator that communicates with the Internet.

Since this refrigerator performs communication using ultra-close proximity communication called an RFID tag, it does not mistakenly identify the target device, and there is no problem of solid identification like a system that performs general wireless communication, The usability is improved and the RFID tag data is directly read by the portable terminal, so that there is no security problem as in the case of reading data via a communication network such as the Internet, and the safety is also improved. In addition, a service can be provided by connecting to the Internet via a mobile terminal such as a mobile phone without adding an expensive configuration such as a communication function for Internet communication to the refrigerator itself.

  However, according to a demonstration experiment conducted by the present inventors with the cooperation of the subjects, it was confirmed that the effects of safety and cost reduction as described above were obtained, but the data received by the portable terminal from the RFID tag There was an event that displayed data that was not considered normal, and there was a problem in terms of reliability. For example, when the data transmitted from the RFID tag is door opening / closing frequency data, the door opening / closing frequency data displays a smaller number of times than the original opening / closing frequency. This occurs at the time of data reception after plugging / unplugging the power supply for moving the refrigerator or after power failure recovery, and the data stored in the information storage part of the refrigerator is lost due to power failure etc. It turned out that it originated in transmitting the door opening / closing frequency data after being supplied.

  In addition, as another problem, the frozen food deteriorates, for example, the ice melts and the ice cream becomes soft, and the cooling performance of the refrigerator becomes uneasy. That is, if the power failure state continues for a long time, the frozen food deteriorates, for example, the above-mentioned ice melting occurs, and it is not known whether this is due to the power failure or not, and the cooling performance of the refrigerator becomes uneasy. In particular, refrigerators are goods that are always operated without disconnecting power for 24 hours, and in such circumstances, instantaneous power outages, local power outages, power outages due to home power protection devices, and power outages due to the supply situation of power companies The operation may be stopped due to a power failure due to various causes. In such a case, depending on the power outage time, the atmosphere in the refrigerator and the food temperature may increase, or the frozen food may deteriorate, for example, the above-mentioned melting of ice may occur. In such a case, it is not clear how much power failure has occurred, and if there is deterioration of the frozen food as described above, there is a possibility that the cooling performance of the refrigerator may be uneasy Is foreseen.

  The present invention has been made in view of the above points. First, when communication with high usability and security is possible without adding an expensive communication function, and there is an abnormality in data from the refrigerator, It is possible to know this, and to provide a highly reliable refrigerator and a communication system using the refrigerator.

  In order to solve the above-described problems, the present invention provides a refrigerator that performs RFID wireless communication with a mobile terminal, a wireless transmission / reception unit that performs RFID wireless communication with the mobile terminal, and an information storage unit that stores a use status of the refrigerator And a control unit for controlling the wireless transmission / reception unit and the information storage unit, and a power-on detection unit, and the control unit stores a power supply signal generated when the power-on detection unit detects power-on. At the same time, when a data request is received from the portable terminal for the first time after detection of power-on, the power supply signal data is transmitted from the wireless transmission / reception unit to the portable terminal together with the data stored in the information storage unit.

  As a result, when a data request is received from the mobile terminal for the first time after a power failure occurs and the power is resupplied, the power supply signal data is transmitted to the mobile terminal together with the refrigerator data. It is possible to inform that the current refrigerator data is not normal due to a power outage or the like.

The present invention can perform Internet communication with high usability and security safety without adding an expensive communication function, and when the data received by the user is abnormal due to a power failure or the like before, This can be notified, and a highly reliable refrigerator and a communication system using the refrigerator can be provided without increasing the cost.

  That is, when the user brings the mobile terminal 22 close as shown in FIG. 1, the wireless transmission / reception unit 21 transmits / receives data between the wireless transmission / reception unit 21 and the mobile terminal 22, and data from the wireless transmission / reception unit 21. Is configured to be displayed on a display unit (not shown in FIG. 1) of the portable terminal 22.

  Hereinafter, the configuration of the home appliance service system will be described with reference to FIGS. FIG. 5 is a control block diagram showing a schematic configuration of the home appliance service system, and FIG. 6 is a flowchart for explaining the operation.

  In FIG. 5, reference numeral 23 denotes the door opening / closing detection unit, 24 denotes a number counting unit for counting the number of times the door is opened / closed detected by the door opening / closing detection unit 23, and 25 denotes a number storage for storing the number of times counted by the number counting unit 24. , 26 is a time measurement unit that measures the door opening time (time during which the door is opened) detected by the door opening / closing detection unit 23, and 27 is a cumulative time measured by the time measurement unit 26. The time storage unit 28 for storing is an information storage unit having the number storage unit 25 and the time storage unit 27.

  Reference numeral 21 denotes a wireless transmission / reception unit that transmits door opening / closing frequency data and door opening cumulative time data to the mobile terminal 22 or receives control data from the mobile terminal 22. In this embodiment, the antenna 21a is connected to the mobile terminal 22. It consists of an integrated RFID tag. Reference numeral 29 denotes a proximity communication detection unit that detects when a mobile terminal 22 such as a mobile phone, a smartphone, or a PDA approaches and transmits a data request / control signal. The wireless communication unit 21 itself includes a data request / control signal. When transmission is detected, the wireless transmission / reception unit 21 operates in a dielectric manner.

  Reference numeral 30 denotes a previous day information storage unit which updates and stores data such as the number of times of opening and closing the door on the previous day and the total opening time of the door stored in the information storage unit 28. Reference numeral 30A denotes an abnormality detection unit that detects an abnormality in the refrigerator, for example, an abnormality such as the compressor being operated for an abnormally long time. As a reason why the compressor continues to operate for an abnormally long time, for example, the door packing may be damaged, and the set temperature may not be reached no matter what time the internal temperature passes.

  31 is a power-on detection unit, which detects this when power is turned on, for example, when the power cord of the refrigerator is plugged into an outlet or when power is turned on after a power failure, and generates a power supply signal. The power supply signal is configured to be supplied to a control unit described later.

A control unit 32 controls the operation of the refrigerator. When the wireless transmission / reception unit 21 receives a data request signal, the number of times of opening / closing the door and the total time of opening / closing the door from the information storage unit 28 and the previous day data from the previous day information storage unit 30 are fetched. And when the wireless transmission / reception unit 21 receives control data from the portable terminal 22, the control content of the refrigerator, for example, the set temperature of cooling is controlled based on the control data. To do. Further, when the power supply signal data is supplied from the power-on detection unit 31, the control unit 32 stores this, and when the wireless transmission / reception unit 21 receives a data request signal from the portable terminal 22, This power supply signal data is also transmitted to the wireless transmission / reception unit 21 together with the data from the information storage unit 28 and the previous day information storage unit 30.

  On the other hand, the mobile terminal 22 uses a general mobile phone in this embodiment, and as is well known, a first communication unit 33 that performs near field communication, an antenna 33a thereof, and a second communication unit 34 for call and Internet communication. The antenna 34a, first and second communication control units 35 and 36 for controlling these communication units, a portable control unit 38 including a display control unit 37, a display unit 39 such as a liquid crystal display, and an operation unit 40 such as a touch switch. The storage unit 41 and the like.

  When the portable terminal 22 is switched to the near field communication by the first communication control unit 35 by operating the operation unit 40, the data request signal is transmitted to the other party and the data from the other party can be received, and the display control unit 37 is also received. Switches the display on the display unit 39 and causes the display unit 39 to display the data received by the first communication unit 33. That is, by bringing the antenna 33 a of the first communication unit 33 close to the wireless transmission / reception unit 21 of the refrigerator, data such as the number of door opening / closing operations from the wireless transmission / reception unit 21 can be received and displayed on the display unit 39.

  Further, the mobile terminal 22 can receive various data via the Internet line (not shown) by the second communication unit 34 as in the case of an ordinary mobile phone, and one of them is a refrigerator related to the present invention. Control data, for example, set temperature data, can be captured and transmitted to the wireless transceiver 21 of the refrigerator.

  In the above configuration, the operation will be described below using the control flow of FIG. First, when the user purchases the refrigerator and inserts the power cord into the power outlet for the first time, the power-on detection unit 31 detects this in step 1, generates a power supply signal in step 2, and supplies it to the control unit 32. Remember. This power supply signal is similarly generated and stored in the control unit 32 when the refrigerator is moved and the power cord is disconnected or inserted, or when power is supplied again after a power failure.

  In this state, when the user opens the door of the refrigerator, for example, the right door 11b of the refrigerator compartment 2 for taking in and out the food, the door open / close detection unit 23 detects the door open / close in step 3 and counts the number of times in step 4 The unit 24 counts the number of times and stores it in the number-of-times storage unit 25, and the time measuring unit 26 measures the door opening time, and the time storage unit 27 stores the door opening time cumulatively.

  In step 5, the proximity communication detector 29 confirms whether data is requested. If there is no request, one day (24h) in step 6 passes through a confirmation step for presence / absence of control data and presence / absence of abnormality, which will be described later. If it has not elapsed, the process returns to step 1. If it has elapsed, the door opening / closing count data and the door opening accumulated time data are stored in the previous day information storage unit 30 and then stored in step 7 so far. Reset the number of times the door has been opened and closed, and return to Step 1.

  In this state, when the user transmits the data request signal by bringing the antenna 33a portion of the portable terminal 22 close to the wireless transmission / reception unit 21 of the refrigerator door (step 8), the proximity communication detection unit 29 detects this in step 5. The wireless transmission / reception unit 21 starts operating.

  Then, in step 9, the wireless transmission / reception unit 21 supplies the power supply signal if the door opening / closing number and door opening accumulated time data stored in the number storage unit 25 and the time storage unit 27 and the power supply signal are stored in the control unit 32. Signal data is acquired and transmitted in step 10.

Thereafter, in step 11, it is confirmed whether the data request from the portable terminal 22 is the first time after detection of power-on. If it is the first time, the power supply signal data stored in the control unit 32 is deleted in step 12 and step 6 is performed. If it is not the first time, since the power supply signal data has already been erased, the process proceeds to step 6 as it is.

  On the other hand, the portable terminal 22 receives the data transmitted from the wireless transmission / reception unit 21 in step 13, and displays the data on the display unit 39 of the portable terminal 22 in step 14.

  As a result, the user can know the usage state of the refrigerator, and in this embodiment, the number of times the door is opened and closed and the door opening time. For example, when the number of times is large, the user is careful to reduce the number of times the door is opened and closed. Will be promoted.

  In addition, since the power supply signal data is transmitted and displayed together with usage information such as the number of times the refrigerator door is opened and received when the data is received, the user can also know that the power was turned on before receiving this data. it can. That is, as apparent from the above description, the power supply signal data is transmitted when the data request is received from the portable terminal 22 for the first time after the power-on detection unit 31 detects the power-on. Is erased in step 12, so that the power supply signal data is not transmitted or received at the time of data transmission accompanying the next data request.

  Therefore, if the user receives this power supply signal data with the portable terminal 22 during daily use after purchasing the refrigerator, a power outage or plugging in / out of the outlet due to movement of the refrigerator will occur before the current reception data. It is possible to know that there was an abnormal situation such as Therefore, it is possible to know that the data received this time is after the power is turned on again and is not normal.

  In addition, since the refrigerator in this embodiment acquires data by bringing the mobile terminal 22 directly close to the refrigerator itself that is the target device, even when there are multiple target refrigerators, always touch the target refrigerator during communication. Because you will bring your mobile device with you, you can understand it intuitively, even if you are a child, etc., you can use it without worrying about operation, you can use it with confidence, it is easy to use, and the Internet Since the data is directly received by the target refrigerator and the portable terminal without intervention, there is no security problem and the safety is improved.

  Moreover, since the door opening / closing frequency and the door opening accumulated time which is the use state of the refrigerator are displayed on the display unit 39 of the mobile terminal 22, the refrigerator does not require display power for informing the user of the door opening / closing frequency, etc. As a result, power can be further saved and energy saving in the refrigerator is improved. That is, since the refrigerator can know the number of times of opening and closing the door via the display unit 39 of the portable terminal 22, the refrigerator itself does not consume any power for displaying the number of times of opening and closing the door. Energy saving will be promoted.

  Further, in this embodiment, the proximity communication detection unit 29 is provided on the refrigerator side, and the wireless transmission / reception unit 21 generates dielectric data only when the proximity communication detection unit 29 detects that the data request / control signal is transmitted. Since transmission is performed, the wireless transmission / reception unit 21 does not consume power, and further energy saving can be achieved.

  On the other hand, the number of times the door is opened and closed and the accumulated door opening time data acquired by the mobile terminal 22 as described above are the same as those used for mobile phones by the user through a predetermined location such as an energy-saving service center or a person who is on duty. Can be sent to a parent.

  Therefore, for example, a company such as an energy saving service center looks at the door opening / closing frequency and door opening accumulated time data transmitted from the mobile terminal 22 and stores control data of the refrigerator, for example, set temperature data of the internal cooling temperature, in the mobile terminal 22. Can be sent.

  When the user who has received the set temperature data again brings the portable terminal 22 close to the wireless transmission / reception unit 21 of the refrigerator and transmits a control signal in step 15, the wireless transmission / reception unit 21 enters an operating state in the same manner as described above. In step 16, it is confirmed whether or not there is a control signal. As a result of confirmation, if yes, it is checked in next step 17 whether the abnormality detection unit 30A has detected an abnormality. If there is an abnormality, the process proceeds to step 6 without doing anything. In step 18, the set temperature of the refrigerator is updated to set temperature data that is control data transmitted from the portable terminal 22.

  The update of the set temperature is as follows according to the status of the door opening / closing frequency and the door opening accumulated time data.

  That is, as one example, the control data when the door opening / closing frequency and the door opening cumulative time are large is data for setting the set temperature high. As a result, when the number of times the door is opened and closed, the internal temperature tends to rise and the compressor starts to operate each time, and the power consumption tends to increase. Even if it rises a little by opening and closing, it can suppress that a compressor operates, and can suppress power consumption.

  Further, the control data when the door opening / closing frequency and the door opening cumulative time are short are data for setting the set temperature low. As a result, when the number of doors open / closed is small, the internal temperature rise is small and the temperature is kept low when the doors are open / closed. In contrast, when the temperature of the food is kept low during this period, and the number of times the door is opened and closed increases, the food temperature can be kept low even if the temperature inside the chamber rises somewhat, and it is consumed. Good food cooling can be maintained without increasing power.

  As described above, this refrigerator can transmit control data from the portable terminal 22 according to the number of times the door is opened and closed and the total opening and closing time, and the conditions can be changed so that the operation of the refrigerator itself is a low power consumption operation. A large energy saving effect can be expected together with the power saving by reducing the number of times the door is opened and closed by the user who has displayed the number of times the door is opened and closed and the accumulated opening and closing time on the display unit 39 of the portable terminal 22.

  Further, the refrigerator of this embodiment includes a previous day information storage unit 30 for storing the previous day data of the door opening / closing number or opening time from the door opening / closing detection unit 23, and the door is based on the data from the previous day information storage unit 30. Control data for increasing the set temperature is output to the control unit 32 a predetermined time before the time period during which opening and closing increases. As a result, the control unit 32 changes the set temperature to a low level a predetermined time before.

  In this way, by lowering the set temperature and lowering the internal temperature before the time period when the door open / close increases and the internal temperature tends to rise, the number of door opening / closing increases and the internal temperature decreases slightly. Even if it rises, the effect on food can be made minute, and good food cooling can be maintained without increasing power consumption.

  The refrigerator further includes a refrigerator abnormality detection unit 30A. When the abnormality detection unit 30A detects an abnormality, the control unit 32 changes the control contents as described above even if control data is received from the portable terminal 22. It is set as the structure which does not perform.

  As a result, there is little opening and closing of the door when there is an abnormality in the refrigerator, for example, when the temperature does not reach the set temperature regardless of how long the internal temperature has passed due to damage to the door packing, and the compressor continues to operate It is possible to prevent the occurrence of a failure that wastes electric power by continuously changing the temperature to a low level and keeping the compressor operating at a higher capacity.

(Embodiment 2)
Although this Embodiment 2 is not illustrated, when transmitting refrigerator data to the mobile terminal 22 for the first time after turning on the power in Embodiment 1, the control unit 32 is transmitting refrigerator data such as the number of times the door is opened and closed. The power supply signal data is transmitted to the mobile terminal 22 a plurality of times and then deleted.

  As a result, even if the user overlooks the power supply signal data transmitted to the mobile terminal 22, the power supply signal data is transmitted several times, so that the user can always confirm this, and the current data It is possible to know more reliably that there is an abnormality, and the reliability is further improved.

FIG. 7 is a flowchart showing the control of the third embodiment. The same parts as those in the first embodiment are denoted by the same reference numerals, description thereof is omitted, and only different portions are described. Other than this flow, it is the same as in the first embodiment, and a description thereof will be omitted.

  In the third embodiment, the power supply signal data in the first embodiment is erased in step 11 when a data request is made from the portable terminal 22 for the first time after the power is turned on. After the power is turned on, that is, when a predetermined period, for example, about 3 days elapses after the power supply signal is generated, the control unit 32 deletes the power supply data.

  Thus, for example, if the user is traveling and there is no data request by the user for a long period of time, for example, about 3 days, even if there is a power failure before the data request and the data is abnormal, 3 days have passed If this is the case, the abnormality will hardly become a problem (if the first data request after the power supply signal is generated is three days later, send the power supply signal data at that time to inform that there was a power failure etc. Therefore, it is not necessary to store and hold power supply signal data at all times. Therefore, in this embodiment, when a predetermined period elapses after the power is turned on, the power supply signal is erased, and it is not necessary to secure a memory amount for storing and holding the data.

(Embodiment 4)
FIG. 8 is a flowchart showing the control of the fourth embodiment. The same parts as those of the first embodiment are given the same reference numerals, and the description thereof is omitted. Only different parts will be described. Other than this flow, it is the same as in the first embodiment, and a description thereof will be omitted.

  In the fourth embodiment, the power supply signal data in the first embodiment is erased in step 11 when there is a data request from the portable terminal 22 for the first time after the power is turned on, but in this fourth embodiment, the portable terminal 22 is erased. After the data request is received from the control unit 32, the control unit 32 deletes the power supply signal data after a predetermined time for the data request in step 11b.

  As a result, even if the user overlooks the power supply signal data at the time of receiving the first data, the power supply signal data is transmitted again at the next data request within the predetermined time, so that it is surely known that a power failure has occurred. Thus, the reliability can be further improved.

(Embodiment 5)
FIG. 9 is a flowchart showing the control of the fifth embodiment. The same parts as those of the first embodiment are denoted by the same reference numerals, description thereof is omitted, and only different portions will be described. Other than this flow, it is the same as in the first embodiment, and a description thereof will be omitted.

  In the fourth embodiment, when there is a data request from the portable terminal 22, it is checked in step 11 whether the data request is the first time after power-on, and in the case of the first time, only the power supply signal data is transmitted in the next step 10a, Thereafter, in step 12, the power supply signal data is erased and the process proceeds to step 6.

  In the case of the fifth embodiment, when a data request is received from the portable terminal 22 for the first time after power failure occurs and power is supplied again, only the power supply signal data is transmitted to the portable terminal 22. In addition, it is possible to reliably recognize that the current refrigerator data is not normal due to a power failure or the like before receiving the current data. In particular, in this case, since no refrigerator data is displayed and only the power supply signal is displayed, the user can always notice abnormalities, and the reliability is greatly improved.

  In addition, when the data request from the portable terminal 22 is the second time or later, the process proceeds from step 11 to step 9, and, as in the first embodiment, the refrigerator data such as the door opening / closing frequency is transmitted, and the user knows this. Will be able to. Other operations are not described, but are the same as those in the first embodiment.

(Embodiment 6)
FIG. 10 is a control block diagram illustrating a schematic configuration of a home appliance service system including a refrigerator and a portable terminal according to the sixth embodiment, FIG. 11 is a flowchart illustrating an operation in the home appliance service system, and FIG. FIG.

  Hereinafter, although it demonstrates using FIGS. 10-12, the part similar to Embodiment 1 already demonstrated attaches | subjects the same number, description is abbreviate | omitted, and only a different part is demonstrated.

  In the sixth embodiment, the fact that there was a power outage and the like, and the extent of the power outage time are also notified.

  That is, in the sixth embodiment, as shown in FIG. 10, the refrigerator control unit includes a power failure time detection unit 46 including a combination of a timer counter 43, a nonvolatile memory 44, and a power failure detection / time calculation unit 45, When a power failure is detected, the power failure time is calculated and stored and input to the control unit 32.

  Next, the operation will be described with reference to FIGS. In the sixth embodiment, as shown in FIG. 11, when power-on is detected in step 1, a power supply signal is generated and stored in step 2, and the timer counter 43 starts counting in step 19. Thereafter, when the user transmits the request signal by bringing the mobile terminal 22 close to the mobile terminal 22, the request signal is detected in step 5, the refrigerator data is acquired and transmitted from the information storage unit 28 in steps 9 and 10, and the mobile terminal The wireless transmission / reception unit 21 of the refrigerator control unit transmits the time held by the refrigerator control unit 22 and stores it in the memory 44 of the power failure time detection unit 46. Thereafter, the presence or absence of a power failure is confirmed in step 21, and if there is no power failure, the operation is the same as in the first embodiment, but the time count in step 20 by the timer counter 43 is continued.

  When a power failure occurs in such a state, the power failure time detector 46 detects the power failure at step 21 and calculates the power failure time at step 22. An example of the calculation will be described with reference to FIG.

First, when a data request X0 is made at the portable terminal 22 after an appropriate time has elapsed since the power plug of the refrigerator is connected to the power outlet of the house and the use is started, the refrigerator obtains time information from the portable terminal 22 to obtain the current time, in this example Then, 7:00 is acquired X01 and stored in the memory 44. At this time, the portable terminal 22 receives a power supply signal from the information storage unit 28 together with normal data.

  Thereafter, when a data request X1 is made at the portable terminal 22 after an appropriate time has elapsed, the memory 44 obtains X11 and stores the time data at that time, in this example, 11:30. At this time, the portable terminal acquires only the refrigerator data from the information storage unit 28.

  Next, when a power failure occurs after that, the power failure detection unit / time calculation unit 45 detects the power failure at step 21 and stores the time obtained by adding the time counted by the timer counter 43, in this example, 14:00.

  Thereafter, when a data request X2 is made at the portable terminal 22 after an appropriate time has elapsed, the memory 44 obtains X21 and stores the time data at that time, in this example, 21:30. At this time, the power failure detection / time calculation unit 45 calculates the power failure time. That is, 7.5 hours are calculated by subtracting the power outage occurrence time 14:00 stored in the memory 44 from the time acquired when data is requested by the portable terminal 22, in this example, 21:30. The time counted by the timer counter 43 from 5 hours to the time when data is requested from the time of the power failure to 21:30, in this example, 6.5 hours is subtracted to calculate and calculate the power failure time of 1 hour ((21 : 30-14: 00) -6.5h = 1h). Then, the power failure time 1h is transmitted to the portable terminal 22 together with the refrigerator data and the power supply signal data stored in the information storage unit 28 in the portable terminal 22 that requested the data.

Thereby, the user can know that there is a power failure before the data acquisition due to the presence of the power supply signal data and the acquired data is not normal, and can also know the power failure time.
As a result, the ice stored in the refrigerator is melting and sticking, or even if the ice cream is soft, whether the ice melt or ice cream is soft is due to a power failure. It will be possible to judge.

  In particular, refrigerators are products that are always operated without disconnecting the power for 24 hours. In such circumstances, instantaneous power outages, local power outages, power outages due to the operation of home power protection devices, and power outages due to the supply situation of power companies The operation may be stopped due to a power failure due to various causes. In such a case, depending on the power outage time, the atmosphere in the refrigerator and the food temperature may increase, or the frozen food may deteriorate, for example, the above-mentioned melting of ice may occur. In such cases, it is not clear how much power failure has occurred, and if the frozen food is deteriorated as described above, there is a possibility that the cooling performance of the refrigerator may be anxious. However, in addition to the power outage as in this embodiment, the user is also notified of the time of the power outage, thereby eliminating the concern about the cooling performance of the refrigerator and improving the reliability of the refrigerator. Can be effective.

  In this embodiment, the power failure time detection unit 46 is described as a combination of the timer counter 43, the nonvolatile memory 44, and the power failure detection / time calculation unit 45. However, the power failure time is detected. Needless to say, any configuration can be used as long as it can be stored.

  In the above description, the example applied to the first embodiment has been described. However, the present invention can also be applied to the second to fifth embodiments. In the case of the fifth embodiment, since the control flow is slightly different from the case of the first to fourth embodiments, FIG. 13 is added. However, the same numbers as those newly added in FIG. It is added and explanation is omitted.

  Also in this seventh embodiment, as in the previous embodiments, the user can know the presence / absence of an abnormality based on the presence / absence of power supply signal data, as well as the number of door opening / closing times and the total door opening time, by looking at this display unit 42. It is possible to expect the same effect as each embodiment.

  As described above, the refrigerator described in this embodiment transmits power supply signal data to notify the user when data is requested for the first time after power-on, and notifies the user of the abnormality. What has been described in the above is a form for realizing the present invention, and various modifications can be made within the scope of achieving the object of the present invention.

  For example, in each of the above embodiments, the power supply signal data is displayed together with the refrigerator data on the display unit 39 or 42. However, this may be notified by voice. In the present invention, the display unit Includes those that provide voice notification. Moreover, although the refrigerator data transmitted to the portable terminal 22 from the radio | wireless transmission / reception part 21 was made into both the door opening-and-closing frequency | count for a power-saving enlightenment, and door opening total accumulation time, this may be either or may contain other data further It may be.

  As described above, the present invention can perform Internet communication with high usability and security without adding an expensive communication function, and the refrigerator data received by the user is abnormal due to a power failure or the like before that. If this is the case, this can be notified, and a highly reliable refrigerator can be obtained without incurring an increase in cost. Therefore, it can be widely applied to business use as well as home use.
