JP 2004-344223 A JP 2007-282938 A JP 2005-218489 A

  However, all of the technologies disclosed in Patent Documents 1 to 3 determine the life of parts and products based on the frequency of use and the number of times of use, prompt the replacement of parts by notification, operation, and stop of driving. Since the continuous use is only prohibited, it is not possible to cope with the end of the life of parts or products due to the influence of aging in the non-use state even though the frequency of use of parts and products has not reached the limit. In addition, since the life described in Patent Documents 1 to 3 only determines the life at one reference point corresponding to the part or product, even if it has reached the life before the set life time, I can not cope.

  The purpose of the present invention is to ensure the safety of parts, products and use under the service life, including the service life of the product regardless of use or non-use, based on one time measurement from the date of manufacture of the product. It is to provide home appliances that can be designed with a high degree of freedom.

  The home appliance of the present invention is a time measuring means, a determining means for determining a replacement time corresponding to a part based on the time measured by the time measuring means, and a notifying means for notifying that it is a component replacement time corresponding to the replacement time determined by the determining means. And a use restricting means for restricting the use of the product in accordance with the limit time of use of the product determined by the judging means, and the time measuring means keeps time from the date of manufacture of the product, When the determination means determines the first set time corresponding to a predetermined part before determining the limit time of use of the product from the date of manufacture at the age of life regardless of whether it is used or not, The notification means notifies that it is time to replace the part, but the use restriction means does not work and the product can be used continuously.

  In such a configuration, the time measuring means starts measuring from the date of manufacture of the product, so the time information regardless of whether the product is used or not used is used as the time information of the product regardless of whether the product is used or not used by the judging means. It is used for the determination of the end of life and enables the use restriction measure by the use restriction means at the time of aging life, while determining the first set time corresponding to the predetermined part before reaching the aging life time of the determination means. In addition, the notification means about the replacement of the part by the notification means at the time of the first setting can be performed. Under the conditions at this time, the use restriction means does not work, and the product can be used continuously. The replacement can be promoted according to the standard life level, and the replacement can be performed with a low probability of reaching the actual life.

  In the above, when the determination unit determines the second setting time point before determining the aging life time point of the product after the first setting time point has passed, the notification unit continues to notify the guidance recommending the inspection of the product. However, the use restriction means does not work and the product can be used continuously.

  In such a configuration, in addition to the above, further, after the first set time, regarding the continuous use of the product that has undergone maintenance such as replacement of parts, the timekeeping information by the timekeeping means is used for the determination of the aging life timepoint by the determination means. For the determination of the second setting time before reaching, it is possible to make a notification measure recommending the inspection by the notification means at the second setting time, and under the conditions at this time, the use restriction means does not work and the product Can be used continuously, and the inspection of the necessary range at this time is promoted, and the life and maintenance of parts and products in case of emergency can be dealt with.

  In the above, the use restricting means restricts the use of the product when the judging means judges the aging time of the product after the second set time has elapsed.

  In such a configuration, in addition to the above, even after the second set time has elapsed, the time keeping regardless of the use or non-use of the product by the time-measurement means regarding the continuous use of the product that has undergone maintenance such as inspection and parts replacement. The information is used to determine the aging life of the product by the judging means, and the use of the product can be restricted by the use restricting means at the time of the aging life of the product, so that it can be used regardless of whether the product is used or not used. can do.

  In the above description, the first set time is further changed according to the use status of the part or product stored in the storage means after the date of manufacture of the product. It can be characterized in that the lifetime is fixed.

  In such a configuration, in addition to the above, the time measuring means only continues the time measurement from the date of manufacture of the product, but the means for storing the parts or products used since the date of manufacture is stored. By simply changing the first setting time according to the stored usage status, you can set the time to allow for the replacement time according to the usage frequency of parts and products and the time fluctuation that reaches the end of the service life. The second setting time point and the aging life can be fixed regardless of the use state, and the determination based on the setting which is always on the safe side by the setting corresponding to the maximum use frequency can be performed.

  Further objects and features of the present invention will become apparent from the following detailed description and drawings. Each feature of the present invention can be employed alone or in combination in various combinations as much as possible.

  According to the household electrical appliance of the present invention, the determination means is based on the timekeeping information measured regardless of whether the product is used or not from the date of manufacture of the product by the timekeeping means. In the unlikely event that the aging life is exceeded, the use restriction measures will be taken by the use restriction means at the time of the aging life, and the aging life including the shipment waiting period regardless of whether the product is used or not used is exceeded. Informing means at the first setting time point based on the determination at the first setting time point corresponding to the predetermined part before reaching the aging life time point by the determining means while restricting the use so as to ensure the safety of use. In addition to prompting the user to replace the relevant part, the product can be used continuously without restricting the use of the means to restrict the use of the part. Exchange It is urged without causing inconvenience and confusion, and parts are replaced with a low probability of reaching the actual life, so that they can be used stably without management from the manufacturer side from this point to the first setting point again. Become.

  In addition to the above, regarding the continuous use of the product that has undergone maintenance such as replacement of parts after the first setting time, the time information by the time measuring means is used as the second information before the determination of the aging life time by the determining means. At the same time, the product can be continuously used without any use restriction by the use restricting means, in addition to enabling the notification means recommending the inspection by the notifying means at the second setting time for the determination of the setting time. The inspection of the necessary range is promoted, and the life of parts and products in the event of an emergency, and the maintenance response, it will be used safely without management from the manufacturer side from this point to the second setting point again .

  In addition to the above, regarding the continued use of products that have undergone maintenance such as inspection and parts replacement after the second set point has elapsed, the timekeeping information regardless of whether the product is used or not used by the timekeeping means For use in determining the aged life of a product, use a product that is restricted to use at the time of the product's aged life by means of restricting the use of the product, and use that has a safety problem beyond the aged life regardless of whether the product is used or not used. Can be blocked. For example, storage functions that are not related to safety of use are excluded from the scope of use restrictions, so that the history information related to maintenance such as stored usage status, part name, replacement date, and inspection date related to replacement of parts can be read Can be used to determine the quality of product usage, parts and product quality, and to develop and design the next product.

  In addition to the above, the first set time is changed based on the storage information of the usage status of the part or product from the date of manufacture, based on one type of timing information from the date of manufacture of the product. It is possible to respond to the time of replacement according to the frequency of use of parts and products and the time setting that anticipates time fluctuations to reach the end of life. Regardless of whether the product is used or not, it is always safe to determine whether the product is safe.

  Hereinafter, it explains in detail, referring to Drawing 1-Drawing 8 for an embodiment of household appliances concerning the present invention, and serves for an understanding of the present invention. The following description is a specific example of the present invention and does not limit the description of the scope of claims.

  This embodiment is an example of a household electric pot. However, the present invention is not limited to this, and can be applied to various common household appliances used in homes such as an electric rice cooker to cope with common problems.

When the container 1 is tilted forward to prevent the liquid contents from flowing out through the discharge passage 25 when the container 1 is tilted forward or rolls over at a height position exceeding the full water level in the vacuum double container 3, Is provided.

  The exterior case 2 has an assembly structure in which a metal body 112 is sandwiched between a resin bottom member 111 and a shoulder member 6, and an upward facing portion provided on the inner peripheral lower portion of the opening 12 of the body 1 formed by the shoulder member 6. The upper flange portion 3a of the vacuum double container 3 is placed on and suspended from the stepped portion 12a, and the bottom of the vacuum double container 3 and the bottom member 111 are welded to each other by means of a mounting bracket and screws (not shown). The exterior case 2 is integrated with the connected connection structure, and can be separated.

  The lid 13 is made of synthetic resin and is hingedly connected to a bearing portion 122 at the rear of the shoulder member 6 by a hinge pin 120 to open and close the lid 13 for opening and closing the opening 12 of the container 1 together with the mouth portion 3b of the vacuum double container 3. The body 1 can be opened and closed. Further, the lid 13 is made of a metal, specifically a stainless steel inner lid 126, which closes the mouth 3 b of the vacuum double container 3. A seal packing 127 sandwiched between the outer periphery of the inner lid 126 abuts on the inner periphery of the mouth portion 3b and seals it.

  Further, the lid 13 is formed with a vapor passage 125 for releasing the vapor from the vacuum double container 3 to the outside, and is exposed to the outside, such as the inner opening 125a of the lid 13 facing the vacuum double container 3 and the like. It is formed so as to communicate with the outer opening 125b formed on the outer surface. In the middle of the steam passage 125, when the container body 1 rolls over and the liquid content enters, a safety path 125c is provided to delay the arrival to the outer opening 125b by temporarily collecting or detouring the liquid. In addition, when the container body 1 rolls over, the steam passage 125 is provided with a water stop valve 125d at the time of overturning that works by its own weight or the like so as to prevent the invading content liquid from going forward. An appropriate number is provided.

  Further, the front portion of the lid 13 is provided with a lock member 21 that engages with a locking portion (not shown) on the shoulder member 6 side at the closed position of the lid 13 to lock the lid 13 in the closed position. When this occurs, the spring 22 is always urged to the locked position so as to automatically engage with the locking portion 19. Correspondingly, the lid 13 is provided with a lock release member 23 for releasing the lock by retracting the lock member 21. Here, the unlocking member 23 releases the lock of the lid 13 to the closed position, and the unlocked lid 13 is automatically engaged with the shoulder member 6 by the spring biased around the hinge pin 120. open.

  The electric pump 26 is a centrifugal pump provided at a position just below the bottom of the vacuum double container 3, and the content liquid flowing from inside the vacuum double container 3 is directed to the discharge port 25 d facing the outside of the container 1 through the discharge path 25. It is fed out and discharged from the discharge port 25d to the outside for use.

  In the body 1, an overhanging portion 31 is formed to project from the opening 12 of the shoulder member 6 of the body 1 to the front side, and the upper surface of the overhanging portion 31 is an operation portion 30 as shown in FIG. 2. Yes. The operation unit 30 includes switch operation units 46 to 48 and 61 relating to heat insulation selection, re-boiling, hot water supply locking / unlocking, and hot water supply using a resin spring or a movable member, as in the prior art. LED lamps or the like for simply displaying lamps are provided, and switches 46a to 48a and 61a as shown in FIG. An operation board 71 having the display elements is provided. The switches 46a to 48a and 61a and the display elements are connected to a microcomputer 73 mounted on the control board 72 as shown in FIG. The microcomputer 73 drives the water heater 11a, the heat retaining heater 11b, and the electric pump 26 in accordance with the selection from the switches 46a to 48a, 61a, the mode setting, etc., and performs water boiling, heat retaining, re-boiling, discharge of the content liquid I do. Water heating and heat retention are performed when the microcomputer 73 turns on and off the water heater 11a and the heat retaining heater 11b through the relay 75 and the triac 76 based on temperature information from the temperature sensor 74 that detects the temperature of the content liquid.

  In such an electric pot, the seal packing 127 is exposed to high-temperature steam when boiling, and since the heat is kept at about 98 ° C. even during heat insulation, a relatively high temperature is transmitted. However, it becomes a consumable item that deteriorates due to differences in the frequency of use of the electric pot, the frequency of boiling water, the frequency of high temperature insulation, and the like. Further, the seal packing 127 is not exposed to a high temperature, that is, it deteriorates even with aging including non-use of the electric pot. Further, since the contact of the relay 75 is frequently turned on and off, it may be welded and become inoperable even though it is a relatively long span that does not reach the consumables. In addition, the electric pump 26 often reaches the end of its life compared to the aging life regardless of whether the entire electric pot is used or not. The aging life of the entire electric pot is regarded as the design life, etc., which is judged to be unable to guarantee the safety of products and use due to the comprehensive deterioration of components and parts including connection deterioration of the electric circuit.

  The deterioration of the seal packing 127 may cause leakage of high-temperature steam to an unintentional location, outflow of high-temperature content liquid when the container 1 falls, and if left unattended, it is also dangerous for use of the electric pot. Accordingly, early measures are required, but it is reasonable to take measures to replace parts because the life of the seal packing 127 is short compared to the aging life of the electric pot. The same correspondence is suitable for other parts having such a long and short life relationship. However, the deterioration and the aging life of the seal packing 127 and the like are difficult for the user to notice and may be noticed only when there is a steam leak, and the danger cannot be prevented beforehand. In addition, it is the present situation that an unexpected accident is caused by continuing to use home appliances such as old electric pots that have reached the end of their service life.

  In order to cope with these, in the present embodiment, in the control system of the home appliances including the electric pot, as shown in FIG. 3, the time measuring means 81 and the replacement time corresponding to the parts based on the time measured by the time measuring means 81 are shown. A determination unit 82 for determining, a notification unit 83 for notifying that it is a component replacement time corresponding to the replacement time determined by the determination unit 82, and a use of the product corresponding to the product use limit time determined by the determination unit 82. 4 is used, and as shown in FIG. 4, the time measuring means 81 measures time from the production date A of the product, and the determination means 82 sets the time limit of use of the product as the production date. When the first setting time C corresponding to the predetermined part before the determination at the aged life time point B regardless of whether it is used or not used is determined, the notification means 83 is the replacement time of the part. Notify but use Limited means 84 without working products are to be able to continue use. These timing means 81, determination means 82, notification means 83, and use restriction means 84 are all internal functions of the microcomputer 73 shown in FIG. 3, but are not limited to this. Of course, it may be a control device combined in a predetermined unit.

  As described above, since the time measuring means 81 starts time counting from the date A of manufacture of the product, the time information regardless of whether the product is used or not used is used as the time measuring information regardless of whether the product is used or not used by the judging means 82. In the determination of the aging life time B, the use restriction means 84 can be used by the use restriction means 84 at the aging life time B, while the determination means 82 corresponds to a predetermined part before reaching the aging life time B. In order to determine the set time of 1, the notification means 83 at the first set time C can be notified of the replacement of the part, and the use restriction means 84 does not work under the conditions at this time. The replacement of parts can be promoted in accordance with the standard life level, and can be replaced with a low probability of reaching the actual life.

  Here, the notification means 83 can notify that the replacement of a predetermined part is urged by visual display using the liquid crystal display unit 55 shown in FIG. 3. In addition to this, a buzzer sound or pseudo sound using the auditory alarm device 85 is provided. Can also be used for notification. In the case of pseudo sound, visual display can be omitted. Further, at the time D when the replacement of the component is confirmed by an input to that effect, for example, by an ON signal of the switch 86a by the notification reset operation unit 86, the notification means 83 stops the notification as shown in FIG. 82 shifts to the determination of the next first time C from that time D.

  As a result, on the basis of the timekeeping information timed from the date of manufacture of the product by the timekeeping means 81 regardless of whether the product is used or not used, the determination means 82 determines the aging life point B of the product regardless of whether the product is used or not used. The use restriction measure 84 is used at the time of aging life B, so that the use of the product should exceed the aging life including the waiting period for shipment regardless of whether the product is used or not used. The first setting time point C is determined based on the determination of the first setting time point C corresponding to the predetermined part before reaching the aging life time point B by the determination means 82 while ensuring the safety of use. In some cases, the notification means 83 informs the replacement of the part, prompts the replacement of the corresponding part, and allows the product to be used continuously without the use restriction means by the use restriction means 84. To level Therefore, prompt replacement without inconvenience or confusion that is essential is replaced, parts are replaced with a low probability of reaching the real life, and from this point to the first set point again, stable without management from the manufacturer side Will be used. The replacement of the part by the user is an operation of obtaining the part, but depending on the type of the part, the manufacturer may be requested to replace the part. In any case, maintenance will be handled by the voluntary intention of the user.

  As shown in FIG. 4, when the determination means 82 determines the second set time E before determining the aging life time B of the product after the first set time C has elapsed, the notification means 83 However, the use restricting means 84 does not work and the product can be used continuously. Thereby, after the first set time C, regarding the continuous use of the product that has undergone maintenance such as replacement of parts, the time information by the time measuring means 81 is used as the second time before the determination of the aging life time B by the determining means 82. In order to determine the set time E, a notification measure recommending inspection by the notification means 83 at the second set time E can be performed. Under the conditions at this time, the use restriction means 84 does not work and the product While enabling continuous use, the inspection of the range required at this point E is promoted, and it is possible to cope with the life and maintenance of parts and products in the event of an emergency.

  Therefore, after the first set time C, regarding the continuous use of the product that has undergone maintenance such as replacement of parts, the timekeeping information by the timekeeping means 81 is used as the second time before the determination of the aging life time B by the determination means 82. In addition to enabling determination of the setting time point E so that a notification means recommending the inspection by the notification means 83 at the second setting time point E can be performed, the product can be used continuously without use restriction by the use restriction means 84. Urges inspection of the necessary range at this time, and responds to the service life and maintenance of parts and products in the event of an emergency. From this point in time, the second set point E can be used again without management from the manufacturer. Will come to be. Also in this case, as shown in FIG. 4, the notification means 83 stops the notification at the time F when the replacement of the component is confirmed by an input to that effect, for example, the ON signal of the switch 86a by the notification reset operation unit 86, etc. The determination means 82 shifts to determination of the next second time C from that time F.

  Naturally, after the second set time E has elapsed, when the determining means 82 determines the aging life time B of the product, the use restricting means 84 restricts the use of the product. As a result, even after the second set time E has elapsed, regarding the continuous use of the product that has undergone maintenance such as inspection and parts replacement, the timekeeping information regardless of whether the product is used or not by the timekeeping means 81 is obtained by the judging means 82. It can be used to determine the aging life of the product, and can be used to restrict use of the product by the use restriction means 84 at the time B of the product aging life, so that it can cope with the aging life regardless of whether the product is used or not used. . As a result, after the second set time E has elapsed, regarding the continuous use of the product that has undergone maintenance such as inspection and part replacement, the timekeeping information regardless of whether the product is used or not used by the timekeeping means 81 The use of the product is restricted by the use restricting means 84 at the time B of the product at the time of the product's life, and there is a problem with safety exceeding the life of the product regardless of use or non-use of the product. Can be prevented.

  Therefore, for example, by making storage functions not related to safety of use out of the range of use restrictions, the microcomputer 73 stores the date of manufacture stored using the external memory 87 shown in FIG. A, first and second setting points C, E, usage status, part name, replacement date, and inspection date related to the replacement of parts, read out historical information about maintenance and performance of household electrical appliances, and user usage conditions, parts, and products Can be used for quality assessment, development and design of next product. For this purpose, the microcomputer 73 and the external memory 87 require a power supply 88 that backs up even when the power of the home appliance on which they are mounted is turned off. Thereby, it can move to the place where there is no power source for boiling operation of the electric pot, or so-called thermos warming without heating when it becomes a Teiden without losing the timekeeping and storage function. Separately, if a specific operation is used to store the part replacement and inspection date, and the specific operation is used to display the items stored in the specific operation, a specific person, for example, manufacturer maintenance or timed product development Only the person in charge of the design can be involved in the storage and display of the stored contents, and can be prevented from being handled meaninglessly or inappropriately by an unspecified person.

  In addition, the first setting time C varies depending on the use status of the parts or products stored in the external memory 87 after the date of manufacture of the product, but the second setting time E, the aging of the product. The life point B is fixed. As a result, the time measuring means 81 only keeps timing from the date of manufacture of the product, but stores the subsequent parts or product usage status from the date of manufacture A in the external memory 87, By simply changing the first setting time point C according to the stored use state, it is possible to set the time to allow for the replacement time according to the use frequency of the parts and products and the time fluctuation to reach the end of life, and the second setting. Time E and aging life time B are fixed regardless of the use state, and can always be determined with a setting close to the safe side by a setting corresponding to the maximum use frequency. As a result, the first set time C is changed based on the storage information of the part or product use state from the manufacture date, based on the one piece of time information by the time measuring means 81 from the product manufacture date A. It is possible to respond without any excess or shortage of time by considering the replacement time according to the frequency of use of parts and products and the time setting that anticipates the time fluctuations to reach the end of life. It can be fixed regardless of the state of use, and the product and use can be made safe by always making decisions based on settings that are closer to the safety side. Specifically, the deterioration of the seal packing 127 of the electric pot is promoted substantially in proportion to the frequency of boiling, high temperature insulation, full power energization, actual operation and their accumulated time even during the progress to the aging life. This is also effective for seal packing between the inner lid of the electric rice cooker and the pan. In addition, other parts can be handled in the same manner in consideration of the difference in influence.

  However, depending on the usage status count, as shown in FIG. 5, when the influence level becomes high even at the second set time point E or the aging life time point B, the control becomes slightly complicated, but the first set time point Similarly, in the case of C, by changing according to the state of use of parts or products, life measures without excess or deficiency can be made in various parts and the entire home electric appliance.

  More specifically, the first time point C can be set to about 1 to 5 years according to the type of replacement part and can correspond to the life of the entire replacement part. As for the replacement parts for each year, it is preferable to notify every replacement point of the year, and it is preferable to include the part name and type corresponding to the notification interval in the notification. In addition, the second setting time point E can be dealt with as a periodical inspection time point of the entire home electric appliance that exceeds the type of replacement parts as 7 years. The age limit B can be set to 10 years, and use restriction measures corresponding to the recent design life can be taken.

  In this case, since the first set time C is shorter than the aging life time B, it is repeated until the aging life time B is determined, but the second setting time E is not only the aging life time B but the aging life time B. Even if it is repeated, it will not be meaningful because it will exceed the point of time of aging, so repetition will be omitted. However, depending on the content of the maintenance based on the inspection at the second setting time E, the aging life time B may be extended from the initial setting, so that it is preferable that the aging life time B can also be changed. In this case, it is considered that the change may be inappropriate if the user performs it without permission. In order to avoid such a situation, an operation that can be performed by the manufacturer is preferable. Even in this case, there is no problem because the inspection is considered to be the work of the manufacturer.

  Hereinafter, specific control examples relating to the maintenance of home appliances as described above, use restrictions at the time of aging, and use prohibitions will be described together with flowcharts.

First, one basic measure flowchart is shown in FIG. The measure starts from the manufacturing stage of the product, specifically the assembly stage, clears the memory items related to the first and second time points C and E and the aging life time point B at the assembly stage or assembly time, and sets the current time at the assembly time. Timekeeping is started as A at the date of manufacture. Thereafter, the first time point C, the second time point E, and the aging life time point B are set and stored in the corresponding memory while continuing timing. Under these conditions, automatic maintenance compatible control in which the microcomputer 73 and its internal functions are timed, determination means, notification means, use restriction means, and memory are started. In the automatic control, it is determined whether the first set time point C has been reached, the second set time point E has been reached, and the aging life time point B has been reached with reference to the timing information.
When the first set time C is reached, it is determined whether or not the consumable part has been replaced. While the consumable part has not been replaced, the consumable part replacement notification, specifically, the replacement display lighting is continued, and the consumable part replacement is performed. Is performed, the date and time of consumable parts replacement is written in the memory, the consumable parts replacement notification is stopped, and specifically, the consumable parts replacement display is turned off. Next, the current elapsed time corresponding to the first time point C is reset so that the elapsed time is counted again, the consumable part replacement information is reset, and the process returns.

  When the second set time point E is reached, it is determined whether an aging inspection has been performed. While the inspection is not performed, the notification of the aging inspection time, specifically the display is continued, and when the inspection is performed, The date and time are written in the memory, and the notification of the aging inspection time, specifically, the display is turned off. Next, the current elapsed time corresponding to the second time point E and the third set time point B, which is the aging life time point B, is reset so that the elapsed time is counted again, and the information on the aging inspection is reset and returned. To do. The reset of the third setting time point B has the meaning of reducing the load of the counting function by avoiding the long time counting following the counting from the manufacturing date time point A and switching to the counting of the remaining time from the current time E. is there.

  When the third set time point, age B, is reached, it is determined whether an age check has been performed. Incorporation is prohibited, the water heater and the heat-retaining heater are kept off, the main functions that are dangerous to use are stopped, and the actual use is restricted. When the inspection is performed, the notification of the aged life inspection time is stopped, the display is turned off, the operation unit input prohibition is canceled, the water heater and the warming heater are turned off, the elapsed time at the second and third setting points is reset, The product is returned to the set state at the end of the aging inspection, and can be reused after the safety of the product and use has been secured.

  In the example of the basic measure of the flowchart shown in FIG. 7, when the third set time point B is reached and the inspection is performed as compared to the case shown in FIG. Write, and use it for later performance analysis and development and design of products. While the third set time B is not reached, whether or not there is an instruction input related to parts replacement, and an instruction input related to calling an aging inspection time. The presence or absence is determined, and when there is an instruction input, the corresponding data is displayed. Thereby, whenever a user etc. are worried, there exists the convenience which can display and confirm the parts replacement | exchange time and aged inspection time.

  In the specific example of measures in the flowchart shown in FIG. 8, the measures are the same as in any case, starting from the production stage of the product, specifically, the assembly stage, and the first and second time points C, E, Clear the memory items related to the aging point of time B, and start timing with the present time as the manufacturing date point A at the time of assembly. The first time point C, the second time point E, and the aging life time point B are set and stored in the corresponding memory. Under these conditions, automatic maintenance compatible control in which the microcomputer 73 and its internal functions are timed, determination means, notification means, use restriction means, and memory are started. In automatic control, every time a kettle is carried out once while keeping timing, the elapsed time of the first set time C is added for 6 hours, and every time warming is carried out for 1 hour, the elapse of the first set time C It is determined whether the first set time point C has been reached, whether the second set time point E has been reached, and whether the aging life time point B has been reached, with reference to the timing information. The

  When the first set time C is reached, it is determined whether or not the consumable part has been replaced. While the consumable part has not been replaced, the consumable part replacement notification, specifically, the replacement display lighting is continued, and the consumable part replacement is performed. Is performed, the consumable parts replacement notification is stopped, specifically, the consumable parts replacement display is turned off. Next, the current elapsed time corresponding to the first time point C is reset so that the elapsed time is counted again, the consumable part replacement information is reset, and the process returns.

  When the second set time point E is reached, it is determined whether or not an aging inspection has been performed. While the inspection is not performed, the notification of the aging inspection time, specifically the display is continued, and when the inspection is performed, the aging inspection is performed. Time notification, specifically, the display is turned off. Next, the current elapsed time corresponding to the second time point E and the third set time point B, which is the aging life time point B, is reset so that the elapsed time is counted again, and the information on the aging inspection is reset and returned. To do.

  When the third set time point, age B, is reached, it is determined whether an age check has been performed. Incorporation is prohibited, the water heater and the heat-retaining heater are kept off, the main functions that are dangerous to use are stopped, and the actual use is restricted. When the inspection is performed, the notification of the aged life inspection time is stopped, the display is turned off, the operation unit input prohibition is canceled, the water heater and the warming heater are turned off, the elapsed time at the second and third setting points is reset, The product is returned to the set state at the end of the aging inspection, and can be reused after the safety of the product and use has been secured.

  The present invention is applied to home appliances in general, and the use of the product from the date of manufacture, in addition to being able to avoid danger in the event of an emergency due to the use restriction corresponding to the aging life regardless of non-use, Management that allows the parts to be accurately exchanged using the timing information can be achieved on the user's initiative.
