Description

  The present invention relates to maintenance and inspection of household electrical appliances having a communication function.

  Conventionally, many home appliances such as refrigerators, air conditioners, washing machines, vacuum cleaners, lighting, microwave ovens, televisions, and videos are used in the home. Maintenance and inspection of these home appliances are performed when a failure occurs in the home appliance and the user notifies the dealer or manufacturer of the failure, and a maintenance service person dispatches from the dealer or manufacturer to the user's home. It is common to perform repairs by failure, or repair by bringing in some types of products. However, there is a problem that it takes time until the repair of the device is started by the service staff after the failure. In addition, even if the service staff identifies the failure location, there is a problem that it takes more days to obtain the component if the component is not at hand.

  In order to eliminate such problems as much as possible, Japanese Patent Laid-Open No. 2000-121238 (Reference 1) provides a diagnosis function in a home appliance and notifies the service center of the failure by communication means when the home appliance fails. Describes that preparations for repair, such as preparation of replacement parts, are possible. For this reason, an earlier response at the time of failure becomes possible.

  However, in general, when a user stops using a home appliance or when a function that he or she wants to use cannot be used, the use of the appliance or function of the home appliance is not completed until the repair is completed. The part cannot be used. In addition, even if a failure occurs in home appliances, for example, only information such as “refrigerator does not work”, “air conditioner does not cool”, “TV does not appear” is obtained, details of the failure are not known, maintenance service personnel However, after inspecting home appliances at the user's home and grasping the specific details of the failure, there was a problem that it took time to repair, such as preparing a failed part.

  In addition, if the home appliance has a diagnostic function, the failure location can be specified, but the diagnostic function is required for each device, and there is a problem that the price increases in order to perform detailed analysis. .

  As a technique for solving such a problem related to Document 1 as much as possible, the technique described in Japanese Patent Laid-Open No. Hei 4-241563 (Document 2) reports that a user of the device reports a failure of the device through a center telephone. When the center that receives the call instructs the user to connect a telephone line to the device, the operation data is sent from the device to the center to diagnose the failure, and the service person who receives the call goes to the user's home It is. However, in the technique described in this document 2, it takes time for the user to report to the center, and it also takes time for the user to reconnect the telephone line. As a document showing a technique for solving this point, there are techniques described in the following document 3 and document 4.

  In JP 2000-245595 A (reference 3), a showcase controller that collects operation information of a plurality of showcases is provided on the user side, and when this showcase controller detects a failure, an abnormality is reported to the center. It is described that the operation information collected so far is transmitted, the cause of the failure is grasped at the center side, and it is dispatched for maintenance inspection.

  Japanese Patent Laid-Open No. 2000-196769 (Document 4) also describes a similar technique. A device information management device that manages operation information of a plurality of home appliances is provided in the home. This device information management information management device detects a home appliance failure with a failure diagnosis device provided in the home appliance, and periodically The operation information of the home appliances is collected, and if it is a failure, the failure is transmitted to the center and the diagnosis information of the electric product is transmitted. If not, the diagnosis information is periodically transmitted to the center. If there is a failure, the center side analyzes the cause of the failure and proposes it to the service staff to promptly respond.

  In the techniques described in Document 3 and Document 4 described above, the operation of diagnosing a malfunctioning part of the device and identifying the malfunctioning part is performed at the center, but a flag indicating that the device is malfunctioning is provided on the user side. However, there is a problem that a failure diagnosis device must be provided on the user side. For this reason, there is a problem that if the device for failure diagnosis (such as home appliances) is replaced, the software in the failure diagnosis apparatus provided in the home must be changed. Since a diagnostic circuit is provided, it has the same problem as document 1.

  In JP-A-4-344758 (reference 5), the target device is a general household drainage pump, but the center regularly monitors the general household device, and if it is abnormal, the service staff repairs it. It is described to do. In other words, the center reads various operating data stored in this device over a telephone line via a telephone line, and if it is abnormal, the center informs this to the general home and a service person goes out. It is to repair.

JP 2000-121238 A JP-A-4-241563 JP 2000-245595 A JP 2000-196769 A JP-A-4-344758

  Fault diagnosis and maintenance services as described in the above documents 3 to 5 are generally performed by establishing a paid maintenance contract between the service target device user and the center or manufacturer.

  However, the above-described prior art has a problem that the user of the device cannot confirm the performance of the contract and gives anxiety.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a system configuration diagram of one embodiment of the present invention. Reference numeral 1 denotes a system in which network-compatible home appliances are connected. In a home connected to network-compatible home appliances 206 such as a refrigerator 201, a washing machine 202, a microwave oven 203, an air conditioner 204, and an illumination 205 by a home network in a general home 2. The server 200, the server 300 in the service center 3, and the mobile phone 4 as a user's mobile terminal are connected to a public line such as the Internet.

  A refrigerator 201 will be described as an example of the network-compatible home appliance based on FIG. The refrigerator 201 is divided into a refrigerator compartment 212, a vegetable compartment 214, and a freezer compartment 216 by a heat insulating box 211, and food can be taken in and out by the refrigerator compartment door 213, the vegetable compartment door 215, and the freezer compartment door 216, respectively. In order to cool the refrigerator compartment 212, the vegetable compartment 214, and the freezer compartment 216, a refrigeration cycle 220 including a compressor 221, a condenser 222, a decompressor (not shown), a refrigerator compartment cooler 224, and a freezer compartment cooler 226 is provided. Cold air is provided to the freezer compartment 216 by the refrigerator compartment 215, the vegetable compartment 214, and the freezer compartment cooling fan 227. The operation of the refrigerator 201 is controlled by the controller 230. The controller 230 digitally controls the function of the refrigerator, the communication controller 235 having a terminal for connecting the network wiring, the model, the serial number in advance. Etc., and an information recording device 234 that records the operation state. Power is supplied from the household power source via the outlet 231, the fuse 230, and the DC power source 232. Further, the communication controller 235 is provided with a backup power source 236 as a power source of another system so that communication is possible even in the event of a power failure. The refrigerator controller 233 includes an air temperature detector 240, a refrigerating room temperature detector 241, a refrigerating room cooler temperature detector 242, a vegetable room temperature detector 243, a freezer room temperature detector 244, and a freezer room cooler temperature detector 245. Based on the detection values of the condenser temperature detector 246, the compressor temperature detector 247, and the door opening / closing detector 248, the compressor 221, the condenser fan 223, the refrigerator fan 225, and the freezer The room fan 227 is controlled. These detected values and the number of rotations of the compressor 221, the condenser fan 223, the refrigerator fan 225, and the freezer compartment fan 227 of the refrigeration cycle are stored in the information recording device 234.

  The refrigerator 201 is set by the liquid crystal panel 250 provided in the refrigerator compartment door 213. This will be described in detail with reference to FIG. 3, FIG. 4, and FIG. The liquid crystal panel 250 includes a setting item selection tab 251, a setting item display unit 252, an input display unit 253, and input means 254. When the operation setting is selected on the tab 251, the refrigerator item temperature, the vegetable room temperature, and the freezer room temperature are displayed on the setting item display unit 252, and the respective temperatures can be input to the input display unit 253 by the input unit 254. When the communication environment is selected on the tab 251, remote control, periodic inspection, and failure notification are displayed on the setting item display unit 252, and remote control and periodic inspection are input ON, OFF, and a password are input on the input display unit 253. Is possible. In addition to the tab 251, a data erasure switch for erasing the operation information stored in the information recording device 234 at the time of disposal or the like is provided. At this time, in order not to erase the product information, even if the owner is changed due to transfer or the like, the periodic inspection can be performed by newly signing a periodic inspection contract.

  Connected to the server 300 in the service center 3 are a workstation 301 for failure analysis, customer data 302 in which customer information is recorded, product data in which information on each home appliance is recorded, and a printer 304 that outputs analysis results. Although not shown, the server 300 is provided with a communication line so that information can be exchanged with the manufacturer and the store.

  In the customer data 302, as shown in FIG. 6, the customer name, address, e-mail address, product name, model, dealer, periodic inspection service created based on information from the dealer or information from the user The presence / absence of inspection, inspection date, history of failures, etc. are registered. The regular inspection contract is free of charge during the warranty period of the product at the time of purchase, for example, and afterwards it is charged and the contract can be renewed at any time by the user's choice. The contract period and account number are added to the contractor's customer data 302 for a fee, and the amount at the time of the contract is withdrawn from the account for each check.

  When a user purchases the network-compatible home appliance configured as described above, the user enters into a periodic inspection contract through a store, mail, or Internet homepage. Since one year after purchase is a warranty period, maintenance inspection service can be received free of charge during this period. When a contract is concluded, the customer data is registered, and a periodic inspection is performed at regular intervals (for example, every week). As a result of regular inspections, if no abnormalities are found, especially if there is a display device such as a liquid crystal on the user's personal computer or home appliance by e-mail to the user that the abnormality was not found as a result of the inspection Notify this display device. This notice may be mailed by postcard. In this case, the service center server automatically prints out the postcard. As a result, the user can know that the periodic inspection is being performed, and can confirm that the contract is being executed.

  If there is a failure or an abnormality is detected, the server displays the information on a display device in the center, and in some cases prints out. When the user can use the e-mail, if the user's personal computer or the home appliance has a display device such as a liquid crystal, this is notified to the display device by e-mail. In addition, when the user is not in an environment where e-mail can be used, or when the user rejects the e-mail, the service staff notifies the user by telephone. Then, the repair schedule is discussed together with the contents of the failure. Then, the service staff visits the user's house and repairs are performed. Note that an abnormality is a sign of failure, and by detecting this abnormality it can be repaired before the home appliance fails and does not operate. For example, if it is a refrigerator, the food will rot or the frozen food will be thawed completely. There is an advantage that can be normalized before being done.

  The results of these maintenance inspections can be browsed by accessing the server at the target store, or are automatically transmitted from the server to the terminal device such as a personal computer of the store. This makes it possible for the dealer to talk to the customer of the dealer about the cause of the failure, how to use the home appliance, and the like, so that the close contact with the local customer is improved.

  The notification that the maintenance service period expires is made by an e-mail or a postcard generated by the server in the same manner as described above before one year has passed since the purchase of the home appliance. Since the warranty period has passed, it will be a paid service from here. If the warranty period for the failed part continues, the repair cost for this part will be free. If the user wishes to continue the maintenance contract, it returns it to the service center by e-mail or reply postcard. Upon receiving this, the service center performs the work of setting the item of customer data inspection service to “present” and setting “paid” for the paid service. Then, the maintenance service similar to the above is performed. On the other hand, when the user is notified that the maintenance service is not desired, the customer service data is not deleted, and the inspection service item is set to “none”. The reason for not deleting customer data is that the user restarts the service at a later date (especially when many years have passed since the purchase of home appliances, the probability of failure increases). It is prepared for the demand to be made. Moreover, you may notify whether a maintenance contract is performed every year.

  The refrigerator 301 will be described as an example based on the flowchart shown in FIG. 20, if the inspection date described in the customer data 303 by the service center workstation 301 is the current day, the process proceeds to 21, and a password and an operation information request signal are sent to the refrigerator 301 via the server 300, the public line, and the home server 200. Sent. At this time, the periodic inspection in the liquid crystal panel 250 is ON (the user may not want to transmit data even during the maintenance inspection service period. In such a case, the periodic inspection switch is turned off. , Even if the operation information transmission request signal is sent from the server of the service center, this can be ignored), and only when the set password matches the sent password, The data recorded in the information recording device 234 is returned. Upon receiving the data returned in 22, the workstation 301 reads the product data stored in the product data 303 from the product information sent in 23, and in 24 checks whether there is an abnormality in the home appliance.

  First, the refrigerator compartment temperature detector 241 and the vegetable compartment when the refrigerator compartment temperature, the vegetable compartment temperature, the freezer compartment temperature, and the door opening / closing detector 247 set by the operation setting of the liquid crystal panel 250 are not opened for a certain period of time. The temperature detected by the temperature detector 243 and the freezer temperature detector 244 is read and compared with the reference value stored in the product data 303. If the deviation is less than the allowable value, the basic function of the refrigerator is determined to be normal. If it is above the allowable value, it is judged as abnormal. Next, check the function of the individual parts. The number of rotations of the compressor 221, the refrigerator fan 225, the freezer fan 242, and the condenser fan 223 are detected by the set value and the refrigerator temperature detector 241, the vegetable room temperature detector 243, and the freezer room temperature detector 244. Compared with the reference value of the product data from the measured temperature, if the deviation is less than the allowable value, it is determined to be normal. Furthermore, the compressor 221, the refrigerator cooling fan 225, the freezer fan 242, the rotation speed of the condenser fan 223 and the air temperature detector 240, the refrigerator temperature detector 241, the refrigerator temperature detector 242, the vegetables The temperature detected by the room temperature detector 243 and the freezer temperature detector 244 is used to calculate the standard compressor temperature, condenser temperature, refrigerator temperature, and freezer cooler temperature from the equipment data. Compared to the temperatures detected by the room cooler temperature detector 242, the freezer cooler temperature detector 245, the condenser temperature detector 246, and the compressor temperature detector 247, it is determined to be normal if the deviation is less than the allowable value. Above the reference value, an abnormal location is estimated from the part in which the temperature exceeds the reference value and the database recorded in the device data 303. For example, the temperature detected by the refrigerator temperature detector 242, the freezer temperature detector 245, and the condenser temperature detector 246 is lower than the reference value, and the temperature detected by the compressor temperature detector 247 is the reference. If it is higher than the value, it is determined that the refrigerant is leaking.

  In 25, it is determined whether there is an abnormality. If there is no abnormality, the process proceeds to 26, and the user is notified that the operation is normal. At this time, in addition to the e-mail described in the customer data, the address and the inspection result shown in FIG. 8 are printed on the mail using the printer 304. By transmitting to the e-mail address, the user can know the inspection result using a mobile phone or other display device, and there is no need to provide a display function for each home appliance. In addition, the mail can be used to prevent people who do not use the Internet or the like from overlooking the mail. If the home appliance has an electronic mail display function, the result may be transmitted to the home appliance. The sender gives the user a sense of security and reliability by making the name of the store familiar with the user (as described above, the store is in a state where the inspection result of the home appliance can be seen).

  If there is an abnormality in 25, the server 300 displays this fact on the display device in the service center 3, and prints out to the printer 304 in some cases. From the abnormal part determined in 24, the server 300 creates a tool list necessary for repair in 27, detects the stock status of service items from the database, calculates a repairable schedule from the service staff schedule in 28, 29 Then, the user is informed of the abnormal location and repairable schedule as shown in FIG. This contact may be made by a service person. In this case, the server 300 displays or prints out at least the abnormal part and the stock status of the service item.

  If there is an abnormality, in addition to e-mail and postal mail, the dealer may be contacted, and the dealer may visit the user's home to contact the result and adjust the repair date. At 30, the inspection date of the customer data 302 is changed to the next date, and the periodic inspection is terminated.

  Even if no abnormality or failure is found in the regular inspection, home appliances may fail due to an accident such as lightning or water entering the electronic device. In this case, it is common for the user to contact the dealer or the service center by telephone, but it is difficult to explain the failure situation, and the service center service personnel may be able to identify the failure or abnormality. . In order to solve such a problem, when the user determines that the home appliance is abnormal or malfunctioned, the user selects a communication environment on the tab 251 of the liquid crystal panel 250 and presses a malfunction switch.

  When the contact switch for failure communication is pressed, the password for the periodic inspection and the operation information are sent to the workstation 301 via the home server 200, the public line, and the server 300. When the address of the household electrical appliance described in the customer data 302 and the password match at the workstation 301, the operation information sent to the device data 303 is compared in the same manner as in the periodic inspection. Necessary tools and service items will be listed, and the service staff will notify the user of the failure location and repair schedule.

  As described above, in this embodiment, the storage means for recording the operation information necessary for device control and a predetermined password, and the operation information when the password matches the external operation information request signal and the password signal. By providing the means for transmitting, it is possible to grasp the operating state from an external device safely without providing special analysis means for the home appliance. Moreover, unnecessary personal information can be transferred or viewed from the outside by providing a password that is different from the password used by the user to change settings from a mobile phone, etc., and monitor the driving status. There is no fear and it can be used safely.

  By the way, the case where a power supply unit fails as a failure form of household appliances can be considered. In such a case, since power is not supplied to the communication-related boards, maintenance and inspection services cannot be received despite a failure. Therefore, a backup power supply is provided as a power supply system different from the power supply system of the home appliance main body in the power supply device of the transmission / reception means of the remote control network. This backup power supply is a chargeable / dischargeable secondary battery that is charged by being supplied with a charging current from a DC line of a power supply device of the home appliance body. As a result, even if the abnormality occurs in the power supply of the home appliance main body due to the occurrence of an abnormality, and the operation of the main body stops, the communication device operates and the operating state at the time of the abnormality can be transmitted to the service center etc. Can be repaired quickly. Note that examples of the device supplied by the secondary battery include a memory for recording operation information in addition to the communication device.

  Furthermore, a communication means capable of exchanging information with a household electrical appliance in a remote place, a signal that requests a predetermined signal and driving information to the household electrical appliance every predetermined period, and driving information returned from the household electrical appliance; By comparing the device data of household appliances and analyzing whether the operating state is normal or abnormal, it is possible to grasp the presence or absence of abnormalities with high accuracy, and in minor cases, repairs can be made before the household appliances are stopped. It becomes possible. In addition, the device data database can be easily changed, and abnormality determination can always be performed with the latest data. In addition, the operation information returned from the home appliance is compared with the device data of the home appliance, and when there is an abnormality as a result of the comparison, a means for notifying the user of the home appliance of the abnormality location and the inspection date is provided. Thus, the user can know the operating state of the home appliance and can use the home appliance with peace of mind. In addition, by automating a series of these flows by a workstation, the cost can be reduced, and a service can be provided at a low price even in the case of paid implementation. By using mail other than communication means such as e-mail as a contact means, even a user who does not use the Internet at all can receive services.

  In addition, if the communication controller fails and the communication function cannot be used, the failure notification will be from the user as in the case of the conventional example, but since the original functions of home appliances can be used, repairs are not performed quickly. Is less affected.

  In the above embodiment, a refrigerator is used as a network-compatible home appliance. However, an air conditioner, a washing machine, a microwave oven, or the like having a digital control device can perform the same operation.

  The other Example of the power supply system of the network corresponding household appliances of the said Example is described using FIG. In FIG. 10, reference numeral 250 denotes a communication controller board, and the AC power from the outlet 231 branches in the middle and is supplied to the communication controller switch 251, the communication controller fuse 252, and the communication controller DC power supply 253. The DC power obtained by the communication controller DC power supply 253 is supplied to the information recording device 234 and the communication controller 235. The other structure is the same as FIG. Even if the home appliance control power supply board 230 breaks down, power is supplied to the information recording device 234, so that the operation information stored so far can be reliably transmitted to the service center.

  By configuring as described above, the same effect as the above-described embodiment can be obtained, and for a user who does not need a network function, power is not supplied to the communication control board by disconnecting the switch 251. In addition, unnecessary power consumption such as standby power can be prevented.
