JP3788451B2 - Energy-saving warming method and electric hot water storage container to which this is applied - Google Patents

Description

  The present invention relates to an energy-saving heat-retaining method and an electric hot water storage container to which the method is applied, and is used for, for example, an electric pot for home use.

  Electric pots are widely used in homes, workplaces and restaurants. Dependence at home is particularly high, and the power is turned on except for replacement of the content liquid, and heat is maintained except during start-up during re-boiling operation during use and initial boiling due to replenishment of the content liquid. There is a lot going on. However, although the capacity is large, the power consumption is comparable to a large refrigerator, which is a problem in terms of energy saving.

  Therefore, it is possible to save power and save energy by reducing the heat retention temperature including stopping energization by setting the time of the timer in the non-use time zone when going to bed or going out. In addition, users who are concerned about power consumption often respond by meticulously responding by switching off the power source frequently or setting an energy-saving warming mode at a temperature lower than the normal warming. However, this is troublesome because it requires frequent user operations.

To solve this problem, the power information when power is supplied to the main unit, which is separate from the power supply to the control system, is detected and stored in the memory, and the actual usage is automatically analyzed from the stored power information. As a result, there is known an automatic energy-saving and warming method in which the energization circuit breaker is turned off during the time period in which energization is not necessary, and the others are turned on (see, for example, Patent Document 1). Patent Document 1 discloses power information when energizing a main body, that is, average power per unit time, predetermined timing by setting a timer, in order to automatically determine and respond to a time zone for energy saving. Information such as instantaneous power at, phase difference between voltage and current, and dynamic impedance is accumulated, and it is determined from the accumulated data whether it is a time zone in which it is not necessary to energize.

  However, the one described in Patent Document 1 has a large amount of accumulated information for realizing automatic energy saving and warming, and the use frequency is analyzed in a 24-hour cycle, a week cycle, a cycle through four seasons, and the like. Therefore, the clock function and calendar function are required. In order to realize this function, backup with a secondary battery or the like is essential. For these reasons, the product cost will increase rapidly, making it difficult to apply to low-priced intermediate products and lower.

  Therefore, the present inventor has come to consider that automatic energy-saving and warming can be realized at a low cost by a combination of actual use data and simple timing such as a 24-hour timer starting from power-on at an arbitrary time. It was. However, as a result of various experiments and examinations, the actual data is handled based on simple timekeeping. If there is a power outage in the automatic energy saving mode, the time measurement stops and the time recognition of the accumulated actual data is incorrect. It became clear that there was a problem that energy-saving heat insulation deviated from the actual use situation.

  The purpose of the present invention is based on such new knowledge, and is able to store actual data even in the event of a power outage while realizing automatic energy-saving warming at a low cost by handling the actual actual data in a simple manner. The purpose is to provide an energy-saving heat-retaining method that does not have any problems and an electric hot water storage container to which this method is applied.

To achieve the above object, energy saving insulation method of the invention to provide for practical use with the discharge to continue to use state while normally kept liquid contents using an electric hot water storage vessel, clock function, calendar function Energy savings at a temperature lower than the normal heat retention during the non-use time period automatically determined in 24 hour units from the actual use results data accumulated while updating in 24 hour units when measuring only the time that does not depend In the automatic energy saving mode where warming is performed and otherwise normal warming is performed, when the power failure state continues for the first predetermined time, the accumulated performance data is reset and the performance data is accumulated from the beginning. reset the configuration of the energy saving insulation when a predetermined time has elapsed, when the first is a power failure within a predetermined time feature to correct to use by shifting the period of elapsed time per actual data It is.

In such a configuration, the content liquid at a satisfactory temperature can be obtained as it is or with only a slight rise in temperature by using the electric hot water storage container while keeping the content liquid normally warm and continuing the use state for actual use with discharge. For the convenience of use so that it can be used without waiting time or with a little waiting time, the accumulated data is updated while being updated in units of 24 hours with the clock function and calendar function. During periods of non-use automatically determined from actual usage data, energy-saving warming is performed at a temperature lower than the normal warming, so that there is no actual use by the user, even if it is considered irregular, time zone In the unlikely event of actual use, the actual use without any complaints about the temperature is possible with the waiting time between the initial start-up and the normal heat retention. In Yichun is given.

In addition, since the automatic determination of the non-use time zone is done on a daily basis, the accumulated actual use data is handled on a simple timing that repeats every 24 hours to see only the passage of time regardless of the clock function or calendar function. Te, electric hot water storage vessel irrespective of unequal at the start of the use of, accumulated correctly made to correspond to the time zone of the actual use of the actual data and 1 day to determine the energy saving time period, also performs energy saving insulation be able to. Therefore, the clock function, calendar function, and backup using a secondary battery for that purpose are not required and can be realized at low cost.

  In addition, when the power outage continues for the first specified time, the actual data accumulated until then is reset so that it will not be used. In the event of a power outage, that is, when the power supply is stopped, such as when the outlet is disconnected due to liquid supply / discharge, etc., the actual data accumulated before the power outage until the elapsed time exceeds the first predetermined time thereafter Is used, and the execution time of energy-saving warming is recognized in the user's recognition that it is in the automatic energy-saving warming mode because the relationship with the elapsed time in the simple timekeeping restarted by the recovery from the power failure state is shifted. It is possible to avoid the inconvenience that causes the belt to become unsuitable for the actual situation or the distrust.

Also , since the actual data is accumulated from the beginning after resetting the actual data, the actual data is accumulated from the beginning when the power failure is recovered, and the actual use data that does not affect the passage of time in the power outage and the timing are combined. By this, it can be ensured that energy-saving heat insulation without time lag is performed.

In addition , since the actual data is updated in units of 24 hours, it is possible to automatically respond to changes in the actual usage of the user without increasing the accumulated amount of actual data of actual use. It is effective whether the determination of the non-use time zone is based on the performance data for one day or the performance data accumulated repeatedly for a plurality of days. In addition, when there is a power outage within the first predetermined time period, the actual data is corrected so that the elapsed time is shifted, so even if there is a power outage, the energy conservation warming is continued within the first predetermined time. Is used while being shifted by the power outage time, and it is possible to prevent the energy-saving warming from being performed deviating from the actual use results of the user. In addition, this makes it possible to set the predetermined time longer and continue the energy-saving heat retention even during a relatively long power failure, thereby eliminating the problem.

In addition, when the first predetermined time has elapsed, the energy-saving warming setting is reset in conjunction with the above-mentioned actual data. Therefore, even after an automatic response due to a power failure, user settings for automatic energy-saving are required, and the energy-saving mode after the power failure is executed. This makes it easier to recognize that the performance data starts from the beginning, and enhances the understanding that energy conservation and warming is not performed until the data accumulation necessary for determining the non-use time period is completed.

In addition, the electric hot water storage container of the present invention is designed to be used for actual use with discharge by continuing the use state while heating the content liquid with a heater and maintaining the normal heat retention or the energy saving heat at a temperature lower than the normal heat retention. In the electric hot water storage container, a time measuring means for viewing only the time passage not depending on the clock function and the calendar function, and a storage means for accumulating actual use result data for each day in the time measuring information timed by the clock means, During the non-use time period automatically determined from the stored record data, the energy-saving heat retention is performed. In other cases, the automatic power-saving means that performs normal heat retention, and the automatic power-saving mode in which the automatic energy-saving means operates, the power failure state is first. and a power failure measure means a predetermined time continued when the storage unit resets the actual data stored in the first predetermined time, a predetermined time or con Capacitors are discharge time, the power failure measure means is set to the first time is a power failure within a predetermined time feature to correct to use by shifting the period of elapsed time per actual data.

In such a configuration, the content liquid is kept warm and kept in use and subjected to actual use with discharge. In order to facilitate the use so that it can be used in a short waiting time, timekeeping data that is timed by means of timekeeping that does not depend on the clock function or calendar function, which is performed in a state where the electric hot water storage container is energized, Since the actual energy usage data stored and stored in the storage means is used during the non-use time period automatically determined by the automatic energy saving means in units of 24 hours, the energy saving temperature is maintained at a temperature lower than the normal temperature keeping. Even if there is no use, even if it can be regarded as irregular, power saving in the time zone, but in the unlikely event of actual use, in the waiting time between the initial startup and normal warming Warm As it is actually used with no dissatisfaction still, convenience is given to the use.

In addition, since the automatic determination of the non-use time zone is performed in units of 24 hours, the accumulated actual use result data is handled in a simple timing that repeats in units of 24 hours, so that the use time of the electric hot water storage container is not different. Regardless of this, it is possible to determine the energy saving time zone by properly matching the accumulated actual use result data and the time zone of one day, and to execute the energy saving heat retention. Therefore, the clock function, calendar function, and backup using a secondary battery for that purpose are not required and can be realized at low cost.

  In addition, when the power failure state continues for the first predetermined time, the actual use data accumulated so far is reset by the power failure measure means so that it is not used. In case of a power outage, that is, when the power supply is stopped, such as when the power outlet is disconnected due to a power outage, content supply / discharge, etc., the past data is accumulated until the elapsed time exceeds the first predetermined time. Is used, and the execution time of energy-saving warming is recognized in the user's recognition that it is in the automatic energy-saving warming mode because the relationship with the elapsed time in the simple timekeeping restarted by the recovery from the power failure state is shifted. It is possible to avoid the inconvenience that causes the belt to become unsuitable for the actual situation or the distrust.

Further , the first predetermined time is a preset time or a capacitor discharge time, so that the first predetermined time can be simply set according to a predetermined place as a timer function or a capacitor discharge time. It is possible to reliably prevent the confusion of energy saving and warming due to the data shift. In addition, when there is a power outage within the first predetermined time period, the actual data is corrected so that the elapsed time is shifted, so even if there is a power outage, the energy conservation warming is continued within the first predetermined time. Is used while being shifted by the power outage time, and it is possible to prevent the energy-saving warming from being performed deviating from the actual use results of the user. In addition, this makes it possible to set the predetermined time longer and continue the energy-saving heat retention even during a relatively long power failure, thereby eliminating the problem.

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

According to the energy-saving and warming method of the present invention and the electric hot water storage container to which this is applied, the timer function and the discharge time of the capacitor are utilized while the content liquid is normally kept warm and used for actual use with discharge. Non-use time automatically determined in 24 hour units based on simple timekeeping from actual use data accumulated while updating in 24 hour units with timekeeping that looks only at the passage of time regardless of the clock function and calendar function While it is a belt, energy conservation is maintained at a temperature lower than the normal heat retention, and in the unlikely event of actual use, the waiting time between the initial startup and the normal heat retention is used. Simple response that can be resumed by recovering from a power outage with respect to the accumulated data when there is a power outage or power outage during automatic energy saving, even though it automatically responds to actual use without temperature dissatisfaction Although the time relationship in timekeeping is off, resetting the performance data at the time of a power outage exceeding the first time allows the user to recognize that they are in the automatic energy saving warming mode according to the setting, and the execution time of energy saving warming It is possible to avoid the inconvenience that causes the belt to become unsuitable for the actual situation or the distrust. In addition, since the actual data is updated in units of 24 hours, it is possible to automatically respond to changes in the actual usage of the user without increasing the accumulated amount of actual data of actual use. It is effective whether the determination of the non-use time zone is based on the performance data for one day or the performance data accumulated repeatedly for a plurality of days. In addition, when there is a power outage within the first predetermined time period, the actual data is corrected so that the elapsed time is shifted, so even if there is a power outage, the energy conservation warming is continued within the first predetermined time. Is used while being shifted by the power outage time, and it is possible to prevent the energy-saving warming from being performed deviating from the actual use results of the user. In addition, this makes it possible to set the predetermined time longer and continue the energy-saving heat retention even during a relatively long power failure, thereby eliminating the problem. In addition, when the first predetermined time has elapsed, the energy-saving warming setting is reset in conjunction with the above-mentioned actual data. Therefore, even after an automatic response due to a power failure, user settings for automatic energy-saving are required, and the energy-saving mode after the power failure is executed. This makes it easier to recognize that the performance data starts from the beginning, and enhances the understanding that energy conservation and warming is not performed until the data accumulation necessary for determining the non-use time period is completed.

  Hereinafter, an energy-saving and heat-retaining method according to an embodiment of the present invention and an electric hot water storage container to which the method is applied will be described in detail with reference to FIGS. 1 to 9 to provide an understanding of the present invention. The following description is a specific example of the present invention and does not limit the scope of the claims.

  This embodiment is an example of a household electric pot, and an insulated container is used as the inner container. The heat insulating container of the example shown in FIG. 1 has a container 1 in which a vacuum double container 3 made of stainless steel is accommodated in an outer case 2 made of metal as an inner container. Further, the content liquid in the vacuum double container 3 is heated by the heater 11 to store hot water, and the hot water storage liquid 71 is discharged by a pipe type by either the electric pump 26 or the manual pump 10 such as the manual bellows pump shown in the figure. It is discharged outside through the system 25 to supply hot water for use. However, the present invention is not limited to this. It suffices if the stored hot water content liquid 71 is heated by the heater 11 to store the hot water while performing boiling, normal heat retention, and energy saving heat retention, and to use it. The present invention is effective including that the discharge is not necessarily performed by an electric or manual pump, and the container 1 is tilted, and the discharge is not effective even if it is not heated. However, stainless steel has low thermal conductivity among metals, and has sufficient bending rigidity and strength. And since it has a rust prevention effect and easily exhibits antibacterial properties by containing Cu or the like, it is suitable for an electric hot water storage container for eating and drinking and suitable for providing the vacuum double container 3. Moreover, the vacuum double container 3 does not necessarily need to be accommodated in the exterior case 2 and can be shared by the exterior body. In addition, the operation / control system board 33 equipped with the microcomputer 33a is used to perform operation control according to the operation mode set by the power supply / drive system circuit board 27 and the operation panel 32 and the initial setting. However, this can also be a control means employing various devices including hardware circuits. The operation panel 32 is provided on the upper surface of the protrusion 31 that protrudes forward, for example, like a bowl, formed on the synthetic resin shoulder 6 at the upper end of the container 1. Various switches 48 on the operation / control system board 33 provided inside the operation panel 32 are individually pushed by operating means such as a resin spring integrally formed on the operation panel 32 or a key member provided separately. Although it can be turned on, this is not essential to the present invention, and the specific configuration is not particularly questioned. The microcomputer 33a uses temperature information from the temperature sensor 29 that detects the temperature of the content liquid for boiling water, normal heat retention, and energy saving heat retention. The temperature sensor 29 is individually applied to the center of the single bottom portion to which the heater 11 of the vacuum double container 3 as the inner container is applied. The power supply / drive system circuit board 27 is disposed in the synthetic resin bottom 35 of the container 1 together with the electric pump 26.

  As shown in FIG. 4, the heater 11 includes a water heater 11a and a heat retaining heater 11b. The water heater 11a is on / off controlled by a relay 38, and the heat retaining heater 11b is on / off controlled by a triac 39. is there. However, it is not limited to this. As schematically shown in FIG. 4, the operation panel 32 discharges a liquid crystal display unit 81 that displays a set heat retention temperature, current temperature, current operation mode, danger notification or prompting of necessary operation, and hot water storage liquid 71. Discharge key 82 for supplying hot water, lock / release key 83 for locking or unlocking the discharge operation by the discharge key 82, energy saving key 84 for manually setting the automatic energy saving mode, re-boiling for re-boiling during normal heat saving and energy saving heat holding A key 85, a selection key 86 for selecting whether the temperature is kept at 98 degrees or 90 degrees, a time for setting the timer, and the like, and an up key 88 and a down key 89 for up and down the set numerical value are provided.

  In the present embodiment, the flow rate sensor 87 shown in FIGS. 1 to 4 is provided in the middle of the discharge system 25 so that discharge information such as discharge flow rate, discharge amount, and remaining amount can be obtained. In this way, it is possible to provide a measuring cup key for setting the discharge amount when a discharge operation is performed, and to perform control for discharging only the set discharge amount. In addition, although not shown, as a lamp display, an unlocking lamp, a hot water notification lamp, an energy saving lamp, and the like are provided using LEDs.

  The flow sensor 87 is provided in the middle of the discharge system 25 to detect the state of the liquid flow. Specifically, a sensor blade 87a that rotates in response to a liquid flow accompanying discharge in the discharge system 25, and a rotation sensor 87b that is provided around the discharge system 25 and detects the rotation of the sensor blade 87a. It is composed. The sensor blade 87a is a screw type, but may be of any type. The rotation sensor 87b is a photocoupler composed of a projector / receiver. Corresponding to the fact that the sensor blade 87a is of the screw type, the light projecting / receiving device detects the presence or absence of intermittent crossing by the blade portion accompanying the rotation of the sensor blade 87a in the sensor optical path deviated from the rotation axis of the sensor blade 87a. . The sensor blade 87a receives a rotation proportional to the flow rate and flow rate associated with the discharge of the discharge system content liquid 71a and the hot water storage content liquid 71 in the discharge system 25, and the sensor of the rotation sensor 87b at a speed and time interval proportional to the flow rate associated with discharge. Cross the light path. Thereby, the microcomputer 33a as a control means can determine the flow rate at the time of discharge and the amount of discharged liquid from the number of crossings of the sensor blades 87a detected by the rotation sensor 87b, the time, and the time interval. The flow rate sensor 87 detects the flow of the discharge system content liquid 71a and the hot water storage content liquid 71 by the discharge system 25, and works regardless of whether the discharge is performed by the electric pump 26 or the manual pump 10. Moreover, it works even when the container 1 is tilted.

  The flow sensor 87 may be of another detection method, such as detecting the movement of a magnet embedded in a part of the sensor blade 87a with a single lead sensor. In this case, in particular, the sensor structure is simplified because it is not necessary to have a sensor optical path that passes through the inside of the ejection system 25. Separately, the movement of the float pushed to the discharge port 25a side by the liquid flow in actual use in the discharge system 25 is detected by a photocoupler or a lead sensor, and discharge information is detected by the difference in the moving height and moving speed. You can also

  In addition to the notification of various discharge information detected by the flow sensor 87 as described above, a remaining amount warning by the buzzer 90 can be performed. However, as a precaution, the liquid level sensor 91 including a photosensor is provided for the minimum water level that is required for use in the discharge system 25, and a warning is given by turning on the LED lamp 92 or ringing the buzzer 90. . Note that a thermal fuse 94 is provided in the middle of the power supply circuit to melt and stop energization at the time of abnormal temperature rise due to air blowing.

  The energy-saving and warming method in the present embodiment uses the electric hot water storage container as described above, and keeps the hot water storage liquid 71 normally warmed and continuously used for actual use with discharge. During the non-use time period automatically determined from the data in units of 24 hours, the energy saving warming is performed at a temperature lower than the normal warming, and the automatic energy saving mode in which the normal warming is performed otherwise. In particular, in such an automatic energy saving mode, the accumulated performance data is reset when the power failure state continues for a first predetermined time, for example, around 10 minutes or about 20 minutes.

  Here, the actual use information can be easily obtained by an operation signal of the discharge key 82, a signal when the flow sensor 87 detects the discharge of the content liquid, and the like. However, the present invention is not limited to this, and the rotation of the electric pump 26 or its motor 26a may be detected using an encoder or a photocoupler, and may be used as a detection signal for actual use. In addition, it is also possible to detect actual use by detecting the operating state of the manual pump 10 and the boosted state caused by the operation. In these cases, the rotation state of the electric pump 26 and the motor 26a correlates with the discharge flow rate and discharge amount of the discharge system content liquid 71a and the hot water storage content liquid 71, and the operation speed, operation time, operation stroke, and operation amount of the manual pump 10 are correlated. Using the fact that the number of repetitions correlates with the discharge flow rate and the discharge amount, it is possible to indirectly detect the state of the liquid flow without directly touching the liquid flow, and the presence of the flow sensor 87 is related to the discharge resistance. It is possible to avoid the disadvantages associated with direct detection. The discharge control for the manual pump 10 can be performed by restricting the discharge operation with an electromagnetic device or closing the discharge port or the discharge system 25 with an electromagnetic valve.

  Further, if the operation of the lock / release key 83 is also displayed, an intention to perform the next discharge operation is displayed, so that the discharge operation should be performed with a probability of almost 100%, and an electric signal related to actual use can be obtained. .

  Further, the discharge system content liquid 71a in the discharge system 25 in the electric pot normally maintains the same amount of liquid as the stored hot water content liquid 71 after boiling or during the heat insulation as shown in FIG. However, since the discharge system content liquid 71 a is not heated by the heater 11, the temperature is lower than that of the hot water storage content liquid 71. For this reason, each time the hot water storage liquid 71 is discharged to the discharge system 25, the temperature of the discharge system 25 and its surroundings rises. FIG. 6 shows an experimental example of the temperature change in each part of the discharge system 25 when the temperature is kept at 98 degrees, and FIG. 6 shows an experimental example of the temperature change in each part of the discharge system 25 when the temperature is kept at 90 degrees. Both FIG. 5 and FIG. Is the back side of the operation / control system board 33, II. Is the inside of the box 101 that houses the operation / control system substrate 33 of the protrusion 31, III. Is the surface of the discharge port 25c, IV. Is the back side of the power supply / drive system control board 27, V. Is the surface of the electric pump 26. When the temperature is kept at 98 degrees, the influence of the discharge is large as the temperature is kept high, and a clear temperature peak is obtained by the discharge of the hot water storage liquid 71 at any part of I to V. A clear temperature peak was obtained except for IV. In this case, the number and timing are indefinite, but a temperature peak that was not present during the heat insulation is obtained.

  Therefore, whether or not the hot water storage liquid 71 is discharged by the discharge system sensor 72 shown in FIG. Regardless of whether it is performed by tilting the container 1 or not, an actual electric signal can be obtained. In particular, in the example shown in FIG. 7, the heat conducting member 102 is sandwiched between the operation unit box 101 that accommodates the operation / control system substrate 33 and the discharge port 25 c. Thereby, the response performance of the discharge system sensor 72 with respect to the temperature rise by discharge of the hot water storage liquid 71 at the discharge port 25c of the discharge system 25 can be enhanced. For example, it is preferable to use a silicon sheet for heat conduction as the heat conducting member 102. If a slightly thicker material is sandwiched by using elasticity, the operation portion box 101 and the discharge port portion 25c are not required to be specially formed. With both sides.

  The discharge system sensor 72 as the discharge system temperature detecting means is mounted on an operation / control system board 33 as an existing circuit board in the vicinity of the discharge system 25 as shown in FIG. As described above, since the discharge system sensor 72 is used, it is provided on the existing operation / control system board 33 without any special mounting member or wiring member.

  Further, the operation / control system substrate 33 protrudes to the front part of the shoulder 6 of the container 1 and is located inside the upper surface of the protrusion 31 containing the discharge port 25c of the discharge system 25. Thereby, the operation / control system substrate 33 is located immediately above the discharge port portion 25c of the discharge system 25 built in the protruding portion 31 of the container 1, and the discharge system sensor 72 mounted on the operation / control system substrate 33 is connected to the discharge port portion. Since it is located in the vicinity of 25c, it is easy to detect the temperature in the vicinity of the discharge system 25.

  Moreover, the discharge system sensor 72 is provided on the back surface of the operation / control system substrate 33 as shown in FIG. 7, and is positioned above the discharge system 25, more specifically, above the discharge port portion 25c. Therefore, the heat from the discharge system 25 is easily received, and the temperature of the discharge system 25 is more easily detected.

  Here, the front surface of the operation / control system board 33 is mounted with hardware parts such as the switches 48 and a display lamp (not shown), whereas the back surface of the operation / control system board 33 is a chip type. Since chip parts such as the microcomputer 33a are surface-mounted and the discharge system sensor 72 is made of a chip-type thermistor, both the part cost and the mounting cost can be reduced.

  Based on the data on the actual use P obtained in this way, it is possible to automatically determine the non-use time zone that can be determined to be irregular even if there is no actual use and is suitable for energy-saving and warming. If this determination is made in units of 24 hours, the time for which the electric hot water storage container starts to be used from one day of the day can be determined by simple time measurement in units of 24 hours in which only the time elapsed without the clock function and the calendar function is viewed. Thereafter, the relationship between the elapsed time measured at each time point when the actual use P has occurred and the time at each time point remains unchanged. Such a relationship is not limited to the accumulation of data for one day, but the determination in units of 24 hours does not change even if it is performed for several days, and the average number of actual data actually used increases as the number of determination target days increases. It is possible to increase and easily eliminate irregular usage results, and accordingly, it can be more in line with the user's usage results.

  Here, the non-use time zone determined in units of 24 hours is, for example, irregular even if there is no actual use P for one hour as a specific example, while the actual use is for a predetermined time. It can be easily determined as a time zone that is considered to be actual use, and other times may be handled as a use time zone with actual use P.

Further, as shown in FIG. 8, 24 hours are divided into a plurality of time blocks, specifically, B _{1 to} B _6, and whether or not there is an actual usage P among the time blocks B _{1 to} B _6. However, the block Bm that seems to be irregular actual use may be determined as the non-use time zone Z, and the other time block Bn may be set as the use time zone R. In the example shown in FIG. 8, it is determined from the accumulated data for three days that the time blocks B ₂ and B ₄ without actual use P are the non-use time zones Z ₁ and Z _2, and the other time blocks B ₁ and B _{3 are used.} , B ₅ , and B ₆ are determined as the usage time zone R.

  Here, if the time block B is long, the determination result covers the whole, so it is likely to deviate from the actual state. If the time block B is short, it is difficult to deviate from the actual state, but the number of determinations increases. Is preferred.

  As described above, the hot water content liquid 71 is kept warm while being used for actual use with discharge, and the content liquid at a satisfactory temperature without any waiting time as it is or just by a slight temperature rise, Or, for the convenience of use so that it can be used in a short waiting time, during the non-use time zone Z automatically determined from the accumulated actual use P actual data, energy saving at a temperature lower than the normal heat retention By keeping warm, even if there is no actual use of the user, even if it is regarded as irregular, even while trying to save power in the time zone, for the actual use P in the event of the initial startup, It is possible to use the apparatus without dissatisfaction with the temperature in the waiting time between the normal heat retention time and still provide convenience.

  In addition, since the automatic determination of the non-use time zone Z is performed in units of one day, even when the accumulated actual use P actual data is handled in a simple time count repeated in units of 24 hours, the use start point of the electric hot water storage container Regardless of the difference, it is possible to determine the energy saving time zone by correctly matching the accumulated actual use result data and the time zone of one day, and to execute the energy saving heat retention. Therefore, the clock function, calendar function, and backup using a secondary battery for that purpose are not required and can be realized at low cost.

  In particular, when the power failure state continues for the first predetermined time, the actual use P data accumulated so far is reset so that it will not be used. In the event of a power failure, that is, when the primary power supply is completely turned off, such as when the outlet is disconnected for supplying or discharging the hot water storage liquid 71, the elapsed time is accumulated until the first predetermined time is exceeded. The energy saving warmth is recognized in the user's recognition that the user is in the automatic energy saving warming mode by shifting the relationship with the elapsed time in the simple timekeeping that is resumed by the recovery of the power failure state by using the actual data. It is possible to avoid the occurrence of inconvenience that causes the execution time zone to become inconsistent with the actual situation or the distrust.

  In addition to the above, if the performance data is reset, the performance data is accumulated from the beginning. As a result, it is possible to ensure that energy-saving and warming without time lag is performed by a combination of the actual use P actual data and the time measurement that are not affected by the passage of time in a power failure state.

  In addition, the determination time zone of the non-use time zone Z that has been made first is used, for example, in the case where the determination on the actual use P results of a plurality of days is repeatedly updated in units of 24 hours or an integer multiple thereof. However, even if there is an actual use P, if it is rare such as once in the judgment cycle, it is judged as irregular and the setting of the non-use time zone Z is not changed, and the actual use that is not considered irregular If there is P, processing to update from the setting of the non-use time zone Z to the use time zone R for the time zone can cope with a change in the actual use P performance pattern due to a change in the user's lifestyle, etc. it can.

  However, if the use of the electric hot water storage container is started according to certain rules, specifically, when the use is started at a specific time such as noon, a simple function without a clock function and a calendar function is provided. The time information at the time of actual use P can be replaced with the time information by the time measurement. In this case, a period of high frequency of actual use P such as meals and snacks, a period of time when there is almost no actual use P such as sleeping or going out, etc. are assumed in advance or from the actual use P of the user. Can be judged automatically. Accordingly, if the determination of the non-use time zone is changed according to the use frequency depending on the time zone, it is possible to make a determination suitable for the actual usage pattern of the user P.

  In addition, when the actual use P actual data is updated in units of 24 hours, when the non-use time zone Z is determined for several days, the user's new actual use P for one day is unconditional. Thus, it is possible to automatically respond to changes in the actual usage of the user without increasing the amount of accumulated actual usage P data. This is effective regardless of whether the determination of the non-use time zone Z in units of 24 hours is based on the performance data for one day or the performance data accumulated repeatedly for a plurality of days.

  Instead of user settings, automatic energy-saving warming can automatically perform energy-saving warming according to the setting of the non-use time zone at the same time when the user turns on the power from the first time by the manufacturer and seller's initial settings. Even in such a case, the user can be recognized for such a function by selecting and purchasing a product that has already been initialized as a standard mode. There is nothing to do.

  However, in the present embodiment, the automatic energy saving mode is performed by a user setting by operating the energy saving key 84. As a result, when the user selects and purchases a product that has already been initially set as the standard mode, the execution of the automatic energy saving mode depends on the user's settings, and the automatic response to the execution of the automatic energy saving mode and a power failure in the middle However, it is particularly easy to recognize. As a result, proper use can be achieved without causing confusion or distrust in use.

  Further, as another control example, when the first predetermined time has elapsed, the setting of the energy saving and warming is reset in accordance with the result data. As a result, even after an automatic response due to a power failure, user settings for automatic energy saving are required, making it easier to recognize that the execution of the energy-saving mode after the power failure starts from the accumulation of the actual data of actual use P, and the non-use time The understanding that energy-saving heat insulation is not performed until data accumulation necessary for the determination of the band Z is completed can be enhanced.

  Separately, if the first predetermined time is a predetermined time, it can be easily dealt with by a timer function based on timekeeping or the like, to reliably prevent confusion in energy saving and warming due to an assumed data shift. Can do.

  In addition, when the power outage is within the first predetermined time, if the elapsed time is corrected for the actual data, the energy-saving heat insulation is continued within the first predetermined time even if there is a power outage. Since the data is used after being shifted by the time of the power failure, it is possible to prevent the energy-saving heat retention from being performed out of the actual use record of the user. In addition, this makes it possible to set the predetermined time longer and continue the energy-saving heat retention even during a relatively long power failure, thereby eliminating the problem.

  Separately, if there is no actual use P for a second predetermined time longer than the first predetermined time, a message to that effect is displayed, and when energization to other displays and the heater 11 is stopped, the first predetermined time is displayed. In addition to responding to power outages exceeding the time, when there is no actual use for a second predetermined time longer than that, it is displayed so that the user can always take recovery measures without confusion Then, other displays and the energization to the heater 11 are stopped to make a substantial use stop state. As a result, it is possible to achieve safe use and sufficient energy saving when the user forgets to turn off the power and goes on a trip or business trip.

  Separately, if there is no actual use P for a second predetermined time longer than the first predetermined time, the actual data of the actual use P is reset and the power is turned off to exceed the first predetermined time. In the case where there is no actual use for a second predetermined time longer than that in response to a power failure, the user forgets to turn off the power by turning off the power and traveling or business trip Safe to use and sufficient energy saving when going out. Moreover, since the actual data of actual use P is reset, it is possible to prevent the energy-saving and warming when reused from being performed due to such long-time power outage, based on the actual data with a large time shift. can do.

  In addition, if the temperature difference before and after the power failure recovery is within the specified temperature, if automatic energy-saving control is continuously performed, it corresponds to the difference in whether the hot water content liquid 71 is replaced or re-used in a power failure state due to replenishment. Thus, automatic energy saving control can be continued or prevented from continuing. In this case as well, data correction can be performed using a correction value obtained from a relationship between a predetermined temperature difference and elapsed time.

  In addition, the remaining water amount is determined after the power failure is restored, and if the remaining water amount is equal to or less than a predetermined value, for example, a required water supply value, or when a time that is equal to or less than the predetermined value has elapsed, the automatic energy saving and warming control itself is reset. As a result, in the automatic energy saving mode, after the end of the energy saving and warming in the non-use time zone Z, when the warming up mode is started early in order to shift to the normal temperature keeping, depending on the current remaining amount, it will be empty. Such inconvenience can be avoided. In this case, a manual recovery operation can be omitted by automatically resuming the automatic energy saving and warming when the water supply is detected thereafter.

  In order to achieve the above method, the electric hot water storage container shown in FIGS. 1 to 4 is used while the hot water storage liquid 71 is heated by the heater 11 to perform normal heat retention or energy saving heat retention at a temperature lower than the normal heat retention. As shown in FIG. 4, when the state is continuously used for actual use with discharge, as shown in FIG. 4, the time measuring means 111, the storage means 112 for accumulating the actual use P actual data, and the time measuring means from the stored actual data The automatic energy-saving means 113 that performs energy-saving heat retention during the non-use time zone Z that is automatically determined in units of 24 hours based on the time measured by 111, and that normally performs heat retention as the time-of-use time zone R, and the automatic energy-saving means 113 include In the working automatic energy saving mode, there is provided a power failure measure means 114 for resetting the performance data stored in the storage means 112 when the power failure state continues for a first predetermined time.

  Thereby, the hot water storage liquid 71 is kept warm and kept in use and subjected to actual use accompanied by discharge. Or, for the convenience of use so that it can be used in a short waiting time, when the electric hot water storage container is connected to the household commercial power supply 115 and energized, the time keeping means 111 keeps time keeping. The storage means 112 sequentially stores the actual use P actual data in correspondence with the elapsed time at that time. On the other hand, the automatic energy saving means 113 works according to the setting of the automatic energy saving mode by operating the energy saving key 84, and automatically determines in 24 hour units from the actual use P actual data stored in the storage means 112 based on the timing by the time measuring means 111. During the non-use time zone Z, energy-saving warming is automatically performed at a temperature lower than normal warming. As a result, even if there is no actual use by the user, it can be regarded as irregular even if there is no actual use, while saving power in the time zone, for the actual use P, at the time of initial startup and normal heat retention It is possible to use the system without any dissatisfaction with the temperature during the waiting time between the two and the convenience of use.

  In addition, when the power failure state continues for the first predetermined time, the actual use result data accumulated so far by the power failure measure means 114 is automatically reset so as not to be used. If there is a power outage, that is, the power supply is stopped, such as when a power outlet is disconnected due to a disconnection of a power outlet, a power failure, or supply / discharge of the hot water content liquid 71, the elapsed time will exceed the first predetermined time thereafter. Until the actual data accumulated before the power outage is used and the relationship with the elapsed time in the simple timekeeping resumed by the recovery from the power outage is shifted, the user is in the automatic energy-saving warming mode In recognition, it is possible to avoid inconvenience or distrust that the execution time zone of energy-saving and warming does not match the actual situation.

  Here, the timer function by the time measuring means 111 can be used to set the first predetermined time to a preset time. However, in this embodiment, the discharge time of the capacitor 116 as illustrated in FIG. 4 is set. Specifically, charging is performed during normal use, and the storage unit 112 is backed up using the discharge of the capacitor 116 in a power failure state, and the data stored in the storage unit 112 is retained. . In this case, since the discharge time of the capacitor 116 varies for various reasons, it is set to a stable first predetermined time within the standard discharge time, for example, about 10 minutes, and automatically when the first predetermined time elapses. Cancel the backup. As a result, it is possible to prevent variations in the backup time of actual data at the time of a power failure.

  As described above, the first predetermined time can be simply set as the timer function or the capacitor discharge time in accordance with a predetermined position, and the confusion of energy saving and heat retention due to the assumed data shift can be surely prevented. In addition, although the capacitor | condenser 116 in this example is only for backup, it can be shared or shared with the thing of another use.

  The electric hot water storage container shown in FIGS. 1 to 4 will be described in more detail. As shown in FIG. 1, the electric pump 26 is a centrifugal pump provided in the middle of the discharge system 25 and below the bottom of the vacuum double container 3. The discharge system content liquid 71a flowing into the discharge system 25 is sent out and the stored hot water content liquid 71 flows into the discharge system 25, which is continuously sent out and discharged. The manual pump 10 is a bellows pump as described above, and is built in the lid 13 that opens and closes the upper end of the container 1 together with the mouth of the vacuum double container 3, and is attached to the restoring spring 15 by the pressing plate 14 on the upper surface of the lid 13. Each time the pressure operation is performed against the pressure, pressurized air is sent into the vacuum double container 3 to pressurize the hot water storage liquid 71 and push it out to the discharge system 25 for discharge.

  The lid 13 is formed with a vapor passage 17 for releasing the vapor from the vacuum double container 3 to the outside. The lid 13 is formed on the inner opening 17a of the position facing the vacuum double container 3 of the lid 13 and the outer surface exposed to the outside. It communicates with the outer opening 17b. In the middle of the steam passage 17, when the container body 1 rolls over and the stored hot water content liquid 71 enters, a safety path 17c is provided that delays reaching the outer opening 17b by temporarily storing or detouring it. . As a result, it is possible to take measures such as raising the container 1 before the container 1 rolls over and the content liquid flows out through the vapor passage 17. Further, when the container body 1 rolls over, the steam passage 17 is provided with a water stop valve 18 at the time of falling, which works by its own weight or the like so as to prevent the entering content liquid from proceeding forward. Is provided. In the illustrated embodiment, it is provided at one location just inside the inner opening 17a.

  The front portion of the lid 13 is provided with a lock member 21 that engages with the locking portion 19 on the shoulder 6 side in the closed position to lock the lid 13 in the closed position, and the locking portion when the lid 13 is closed. The spring 22 is always urged to the locked position so as to automatically engage with the spring 19. Correspondingly, the lid 13 is provided with a lock release member 23 for releasing the lock by retracting the lock member 21. As shown in FIG. 1, the unlocking member 23 is of a lever type pivotally supported on the lid 13 by a shaft 24. By pushing down the front end 23a with a thumb or the like and rotating it counterclockwise, the locking member 21 is spring-loaded. It is possible to lift the lid 13 which has been unlocked by lifting the rear end 23b raised by the unlocking operation with another finger and opening it.

  The upper part of the discharge system 25 constitutes a discharge port portion 25c, which is an inverted U-shaped unit, at a portion between the projecting portion 31 of the container 1 and the pipe cover portion 2d on the exterior case 2 side. The part 25c is provided with a water stop valve 34 and a discharge port 25a at the time of overturning / forward tilting. The discharge port 25a is opened to the outside downward through the pipe cover portion 2d.

  A cover plate 36 is applied to the opening in the bottom 35 from below by screwing or partial engagement, and a rotating seat ring 37 is supported and supported on the outer periphery of the cover plate 36 so that it can rotate. When the container 1 is placed on a table surface or the like, it can be rotated lightly on the rotating seat ring 37 to change its orientation.

  In addition, the discharge system sensor 72 provided on the operation / control system substrate 33 monitors the detected temperature while the discharge temperature is not detected as room temperature, and performs various control such as boiling water control, temperature control, and liquid volume determination of the stored hot water content. Can be used for control.

  Hereinafter, according to the flowchart shown in FIG. 9, one control example of the automatic energy saving mode by the microcomputer 33a in the operation / control system board 33 will be described. The actual use P with time information is stored along with the start of time measurement when the power is turned on. For timing, a clock signal or the like that is separately performed may be used. Such an operation may be performed only when energy-saving and warming is performed, but if it is always performed, data can be collected before automatic energy-saving and warming is set. The waiting time until the start of energy saving can be reduced and the waiting time can be eliminated. If the temperature is not kept, the process returns. If the power is being kept, the temperature keeping control is started. However, if there is a power failure, the data is held by a capacitor or the like. When the set time elapses, the holding is released and the data is erased and the control is terminated. Thereby, it is prevented that the past data before the power failure exceeding the set time after the power failure is recovered is used for the energy saving heat insulation.

  If it is not a power outage and is not energy-saving, it will normally return and return. If it is not a power failure and is energy-saving and warming, it is determined whether or not performance data relating to actual use P for three days is accumulated. If it has been accumulated, the non-use time is determined, and if 3 hours or more have not passed without the actual use P, it is determined to be the use time zone R and normal heat insulation is performed, and 3 hours or more and 27 hours or more have passed. If not, it is determined as the non-use time zone Z, and the energy is kept warm. Further, when 27 hours or more have elapsed, the energy saving LED blinks to indicate that the energy is forcibly saved due to long-term non-use, and other displays and the energization to the heater 11 are turned off and turned off.

  The present invention is widely spread and can be applied to electric pots that are frequently used every day. In addition to satisfying industrial applicability, energy conservation is achieved while keeping the convenience of use by keeping warm. High contribution to society.
