Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an energy-saving heat retention method and an electric hot water storage container to which the method is applied, and is used for, for example, a household electric pot.
[0002]
[Prior art]
Electric pots are widely used in homes, workplaces, restaurants, etc., but the dependence on them at home is particularly high, with the power being left on except for replacement of the contents, etc. In many cases, the heat retention is continued except during startup and during initial boiling due to replenishment of the content liquid. However, the power consumption of a large refrigerator is comparable to that of a large refrigerator, which is a problem in terms of energy saving.
[0003]
Therefore, it has become possible to save power and save energy by setting the timer for the non-use time zone when going to bed or going out, such as reducing the heat retention temperature, including stopping power supply. In addition, users who are worried about power consumption frequently take measures such as turning off the power supply or setting an energy saving / heating mode. However, this requires frequent operations by the user, which is troublesome.
[0004]
In order to solve this problem, power information when power is supplied to the main unit, which is different from power supply to the control system, is detected and stored in the memory, and the actual use is analyzed from the stored power information. As a result, it is known that the power supply circuit breaker is turned off during a time period when power supply is not necessary (for example, see Patent Document 1). In the device described in Patent Document 1, power information when power is supplied to the main body, that is, an average power per unit time, a predetermined timing based on the setting of a timer, in order to automatically determine and respond to a time zone for energy saving. Information such as instantaneous power, phase difference between voltage and current, dynamic impedance, etc. is stored, and it is determined from the stored data whether or not it is a time zone where power supply is not required. All of them are made to keep energy saving.

[0006]
[Problems to be solved by the invention]
By the way, there are many patterns frequently used at short time intervals in a time zone of eating and drinking. However, if the energy saving and heat keeping is performed even in a short non-use time period in such a case as in the case of Patent Document 1, the temperature of the hot water drops before the next use rather than waste. Depending on the intended use, such as tea or coffee, which is sensitive to temperature, it is easy to cause dissatisfaction to the user.Depending on the degree of dissatisfaction, special operations for re-boiling to recover hot water temperature and starting up to the set warming temperature, The waiting time is required, which inconveniences the user.
[0007]
In addition, it is convenient to adopt a clock function and a calendar function to set the energy saving time zone and to carry out energy saving heat retention. However, this increases the product cost, and the user has to set the date and time in the early stage of use, which is inconvenient.
[0008]
SUMMARY OF THE INVENTION An object of the present invention is to provide an energy-saving heat retention method that is less wasteful and less likely to cause dissatisfaction or inconvenience to a user, and an electric hot water storage container using the same.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, the energy saving and heat retaining method of the present invention is based on a discharge operation by continuing the use state while keeping the content liquid in the electric hot water container at a normal temperature or at a temperature lower than the normal temperature. For actual use, determine the actual progress of actual use and, among the unused time zones in the determined actual use history, set the unused time zone exceeding a predetermined value as the subsequent energy saving time zone, and set It is characterized by energy saving and heat retention when the energy saving time period is over.
[0010]
In such a configuration, the actual use signal accompanied by the discharge of the liquid content during the use state is an electric signal related to the discharge operation such as an electric discharge operation signal or a discharge operation signal that electrically detects the manual discharge operation. From the obtained actual use signal and the time information at the time of obtaining the signal, it is possible to simply determine the actual use progress. It is possible to easily and accurately set the target time zone for energy saving and heat keeping from the non-use time zone in the lapse of the actual use result determined simply, thereby achieving energy saving. Then, instead of setting all of the determined non-use time zones as energy-saving time zones, set the non-use time zones exceeding a predetermined value in the subsequent energy-saving time zones. Therefore, it is possible to eliminate the dissatisfaction and inconvenience given to the user side by performing energy-saving and heat-retaining at the time of non-use or non-use time when the device is repeatedly used at short time intervals such as eating and drinking.
[0011]
As an electric hot water storage container that achieves such a method, the content liquid is heated by a heater so as to be used for a discharge operation by continuing the use state while maintaining the normal heat or the energy saving heat at a temperature lower than the normal heat. In the hot water storage container, the actual use progress determining means for determining the actual progress of actual use, and the energy saving time after the non-use time zone exceeding a predetermined value among the unused time zones in the determined actual use performance progress. It is sufficient to provide an energy-saving and heat-retaining control means for setting an energy-saving time zone when the energy-saving time zone is set.
[0012]
In the above method, the non-use time or the non-use time zone shorter than the predetermined value is a normal heat retention time zone from a predetermined time before the start point, in a further configuration,
The non-use time or non-use time period shorter than the predetermined value is not set as the energy saving time period, and the normal heat retention time zone is set before the predetermined time before performing the normal heat retention, so the timing of actual use at short time intervals is short. It is possible to cope with a case where the temperature deviates from the normal warm-up time zone occasionally, and there is an advantage that the user is not dissatisfied or inconvenienced. This corresponds to the shift to the front side, but the shift to the rear side can be similarly handled.
[0013]
In addition, the normal heat retention is performed a predetermined time before the time of actual use.
By performing normal warming from a predetermined time before the actual use time, when the actual use time is a switching point from the energy saving time zone to the normal warming time and the normal warming time zone is short, a short time is used. It is possible to cope with a case where the actual use timing at the interval deviates from the normal warm-up time zone at that time, and there is an advantage that the user is not dissatisfied or inconvenienced. This corresponds to the shift to the front side, but the shift to the rear side can be similarly handled.
[0014]
In addition, the time measurement is started at the time of the setting operation of the energy saving time zone, and thereafter, based on the time measurement, the actual progress in the actual use time in the predetermined unit time range is determined, and the actual use in the determined unit time range is determined. Elapsed time set in accordance with the lapse of time in each of the predetermined unit time ranges based on the time measurement until the energy-saving time zone is set for the non-use time zone in the elapsed time for each elapsed time until the energy-saving time zone is reset. In another configuration, it repeats energy saving and heat keeping at another energy saving time.
Clocking can be started at the time of setting operation of the energy saving time zone, so that a clock function and a calendar function are not required, realizing at low cost, and eliminating the need for the user to set the date and time at the time of initial use, It will be easy to use. The actual progress of actual use in a predetermined unit time range from the start of timing is based on the accumulation of a combination of a signal of actual use thereafter and information on the elapsed time until it is obtained, from the elapsed time of actual use. It can be determined as another performance elapsed, and the energy saving time zone is set for the non-use time zone in the actual performance elapsed time according to the determined actual use time within the unit time range, and the energy saving time zone is reset. When the energy saving time zone is set according to the elapsed time set according to the time elapse of the predetermined unit time range based on the time counting up to the time, the energy saving and heat keeping is performed, and the elapsed time management without specifying the time by the clock function and the calendar function is performed. Energy conservation and heat keeping can be achieved in accordance with the actual progress of actual use by the user alone.
[0015]
In a further configuration, the predetermined unit time range is a plurality of days in which 24 hours have elapsed as one day.
In order to more accurately judge the actual progress of actual use of users from accumulated data for multiple days, only the elapsed time management based on the time measurement started at the time of setting the energy saving time zone, there is no clock function or calendar function Can be achieved.
[0016]
In order to achieve such a method, the electric hot water storage container is provided with a time-measuring means for starting time-measuring when setting an energy-saving time zone, and the actual use progress judging means is provided with a predetermined time based on the time measured by the time-measuring means. The elapse of the actual use by the elapsed time of the actual use in the unit time range is determined, and the energy saving heat retention control means determines the energy saving time for the non-use time zone in the elapse of the actual use by the elapsed time of the actual use in the determined unit time range. The band is set, and the energy-saving and heat-retention is repeatedly performed when the energy-saving time zone according to the set elapsed time is reached according to the elapse of the predetermined unit time range based on the clock until the energy-saving time zone is reset. Is enough.
[0017]
The energy-saving time zone reset point is a predetermined cycle time or a point in time when the discharge operation has been performed a predetermined number of times or more during energy-saving heat retention.In a further configuration,
If the energy saving time zone is reset at the predetermined cycle, the elapsed time management will be performed in response to changes in the user's actual usage pattern at regular timings expected due to differences between weekdays and weekends, differences in seasons, etc. This can be dealt with by automatically resetting the energy saving time zone based on the above, and it is possible to respond in a short term to a change that cannot be predicted if it is performed at a short period. In addition, if the energy saving time zone is reset when the number of discharge operations is equal to or more than a predetermined number of times during the energy saving warming, it is possible to respond to the fact that does not match the actual situation regardless of the reason, and the accuracy increases when the number of predetermined times is reduced. However, if the number of energy saving time zone setting operations increases and the predetermined number is increased, the number of energy saving time zone setting operations may be small, but the number of deviations from the actual usage of the user increases.
[0018]
Further objects and features of the present invention will become apparent in the following detailed written description. The features of the present invention can be employed alone or in combination as variously as possible.
[0019]
【Example】
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings 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.
[0020]
The present embodiment is an example of a household electric pot, and uses an insulated container as an inner container. The insulated container of the example shown in FIG. 1 has a container body 1 in which a vacuum double container 3 made of stainless steel is accommodated in an outer case 2 as an inner container, and the content liquid is heated by a heater 11 to store hot water. It has a configuration in which either one of the pump 26 and the manual pump 10 such as a manual bellows pump is discharged to the outside through a pipe-type discharge system 25 to supply hot water for use. However, the present invention is not limited to this, and it is sufficient that the content liquid is heated by the heater 11 to store the water while keeping the water boiling, normal warming, and energy saving warming, and used for use. The present invention is effective including the case where the container 1 is tilted without using a manual pump, and the present invention is also applicable to a case where no water is heated. However, stainless steel has low thermal conductivity among metals, has sufficient flexural rigidity and strength, and has a rust-preventive effect. It contains Cu and it is easy to exhibit antibacterial properties. It is suitable for an electric hot water storage container and is suitable for providing a vacuum double container 3. Further, the vacuum double container 3 does not necessarily need to be housed in the outer case 2 and can be shared by the outer body. In addition, the control board 33 on which the microcomputer 33a is mounted is used for controlling the operation according to the power supply circuit board 27 and the operation unit D and the operation mode set in the initial setting. In addition, control means employing various devices can be used. The operation unit D is constituted by an operation panel 32 provided on an upper surface of a protruding portion 31 protruding, for example, in a beak shape forward of an upper end portion of the container 1, and various switches 48 on a control board 33 provided inside the operation panel 32 are provided. The operation panel 32 has a resin spring formed integrally with the operation panel 32 and a key member provided separately, so that the operation panel 32 can be individually pressed and turned on so as to be turned on. However, this is not essential to the present invention. The specific configuration does not matter. The microcomputer 33a uses the temperature information from the content liquid temperature detecting means 9 for detecting the temperature of the content liquid for water heating, normal temperature keeping, and energy saving keeping. The content liquid temperature detecting means 9 is an inner container sensor 29 individually applied to the center of the single bottom portion of the vacuum double container 3 serving as the inner container, to which the heater 11 is applied.
[0021]
As shown in FIG. 3, the operation panel 32 has a liquid crystal display section 81 at the center thereof for displaying a set warming temperature, a current temperature, a current operation mode, a danger notification, a prompt for necessary operations, and the like, and hot water storage contents around the liquid crystal display section 81. A discharge key 82 for discharging the liquid 71 to supply hot water, a lock / release key 83 for locking or unlocking the discharge operation by the discharge key 82, an energy saving key 84 for manually setting an energy saving mode, a normal heat retention, and a reboil during energy saving heat retention. Re-boil key 85, a selection key 86 for selecting between 98-degree or 90-degree heat retention, a timer setting time, etc., a measuring cup key 87 for setting a discharge amount when a discharge operation is performed, and a set numerical value , An up key 88 and a down key 89. As the lamp display, a lock release lamp 91, a discharge lamp 92, an energy saving lamp 93, and the like are provided using LEDs or the like.
[0022]
The electric pot as the electric hot water storage container of the present embodiment, particularly, as an energy-saving heat retaining method, keeps using the electric hot pot while keeping the hot water storage liquid 71 at normal temperature or energy saving at a temperature lower than the normal temperature. In order to provide the actual use by the discharge operation, the lapse of the actual use result is determined, and the determined non-use time zone X in the lapse of the actual use result is determined. ₁ ..Of Xm, a non-use time zone exceeding a predetermined value Y and a subsequent energy-saving time zone Z ₁ ..Set to Zn and set energy saving time zone Z ₁ ・ ・ Energy saving and heat retention are performed when Zn is reached.
[0023]
According to the operation panel 32 as described above, the discharge key 82 is always operated to discharge the hot water storage liquid 71, and the operation of the lock / release key 83 also indicates the intention to perform the next discharge operation. Therefore, the ejection operation should be performed with a probability of almost 100%, and in each case, an electric signal related to the ejection operation can be obtained. Further, even if the discharge is performed by the manual pump 10, if this is detected by a switch or a sensor, an electric signal of the discharge operation can be obtained.
[0024]
Also, as shown in FIG. 1, the discharge system contents liquid 71a in the discharge system 25 in the electric pot usually keeps the same amount as the hot water storage contents liquid 71 after boiling and keeping the temperature. However, since the discharge system content liquid 71a is not heated by the heater 11, the temperature thereof is lower than that of the hot water storage content liquid 71. For this reason, each time the hot water content liquid 71 is discharged to the discharge system 25 by the discharge, the temperature of the discharge system 25 and the surrounding area rises. FIG. 5 shows an experimental example of a temperature change of each part of the discharge system 25 when the temperature is kept at 98 degrees, and FIG. 6 shows an experimental example of a temperature change of each part of the discharge system 25 when the heat is kept at 90 degrees. 5 and 6, (1) is the back surface of the control board 33, (2) is the inside of the box 101 containing the control board 33 of the protruding portion 31, (3) is the surface of the discharge port 25c, and (4). ▼ indicates the back surface of the power supply / drive system board 27, and ▲ indicates the front surface of the electric pump 26. When the temperature is kept at 98 degrees, the effect of the discharge is large because the temperature is high, and one clear temperature peak is obtained by discharging the hot water content liquid 71 at any of the points (1) to (5). One clear temperature peak was obtained except for ▼, and even in the case of ４, the number and timing are uncertain, but a temperature peak that was not at the time of warming is obtained.
[0025]
Therefore, the temperature of the discharge system 25 or the vicinity thereof is checked whether the hot water content liquid 71 is discharged by the discharge system sensor 72 or the like, whether or not the discharge is performed by the electric pump 26, the manual pump 10, or The determination can be simply made without distinction as to whether the operation is performed with the container 1 tilted.
[0026]
As described above, a signal for actual use can be reliably obtained from any one of the electrical signals related to the ejection. From the actual use signal thus obtained and the time information at the time of obtaining the signal, it is possible to simply determine the progress of the actual use. The non-use time zone X in the actual use actual result determined simply. ₁ ..Target time zone Z for energy saving and warming from Xm ₁ .. Energy can be saved by setting Zn easily and accurately. Then, the non-use time zone X determined as described above ₁ ..Not setting all of Xm as energy saving time zones, but energy saving time zones Z for unused time zones exceeding a predetermined value Y ₁ ..Set to Zn and set energy saving time zone Z ₁ ..Zn, energy saving and warming is performed, so when not repeatedly used at short time intervals such as eating and drinking, or when not in use X ₀ As a result, it is possible to eliminate the dissatisfaction and inconvenience given to the user side by performing energy-saving heat retention.
[0027]
As described above, according to the determination of the progress of actual use using a simple electric signal, the energy saving time zone Z is determined based on the progress of actual use over a longer period of time using a nonvolatile memory or the like. ₁ ······················································································ Zn determination does not require large capacity.
[0028]
As an electric hot water storage container that achieves such a method, the above-described hot water storage content liquid 71 is heated by the heater 11 to continue the use state while heating the water, or keeping the normal temperature, and keeping the energy saving at a temperature lower than the normal temperature. As shown in FIG. 2, in an electric pot to be used by a discharge operation, a real use progress determining means 73 for determining the actual use progress from an electric signal related to discharge and time information obtained from the electric signal, Non-use time zone X in the progress of ₁ ..Of Xm, a non-use time zone exceeding a predetermined value Y and a subsequent energy-saving time zone Z ₁ ..Set to Zn and set energy saving time zone Z ₁ It is sufficient to provide an energy-saving and heat-retaining control means 74 for performing energy-saving and heat-retaining when Zn is reached.
[0029]
The discharge system sensor 72 uses a thermistor or the like, and is a discharge system sensor 72 that can detect the temperature of the discharge system 25 or its vicinity, for example, provided at a position as shown in FIG. The energy-saving and heat-retaining control means 74 can be constituted by a single circuit or device, or a combination of a plurality of circuits or devices. However, in the present embodiment, as shown in FIG. 2, the operation control microcomputer 33a is provided as an internal function.
[0030]
In this embodiment, as shown in FIG. 2, a storage unit 75 for storing the detected actual use result data, that is, information on the time of actual use, is provided. According to the actual use history, different temperatures or temperature changes are performed. In this way, if the time during which there is no actual use is short, consider the effect on the next use, and set a slightly higher energy-saving heat retaining temperature. While maintaining the temperature, near the return, there is no inconvenience in use by utilizing the difference in the actual use history, such as raising the temperature to the predetermined temperature by the boiling mode for the next use and eliminating inconvenience of use In addition, it is possible to set a heat retaining state that is advantageous for energy saving. The storage means 75 uses a non-volatile memory having a backup power supply 76 as shown in FIG. 2 so that the storage contents can be maintained even after the electric pot is turned off, so that the contents can be replaced or washed. Of the stored data before and after the power was turned off in several days cycle, one week cycle, several weeks cycle, one month cycle, several months cycle, and long-term data through four seasons cycle. It is possible to prepare and accurately determine the actual use progress or the use pattern.
[0031]
Further, the discharge system sensor 72 as the discharge system temperature detecting means is mounted on a control board 33 as an existing circuit board near the discharge system 25 as shown in FIG. As described above, since the discharge sensor 72 is mounted on the existing control board 33 without using any special mounting member or wiring member, it does not cause a cost increase.
[0032]
Further, the control board 33 protrudes toward the front of the shoulder 6 of the container 1 and is located inside the upper surface of the protruding portion 31 in which the discharge port 25c of the discharge system 25 is built. As a result, the control board 33 is located immediately above the discharge port 25c of the discharge system 25 built in the projecting portion 31 of the container 1, and the discharge system sensor 72 mounted thereon is located near the discharge port 25c. , It is easy to detect the temperature near the ejection system 25.
[0033]
Moreover, since the ejection system sensor 72 is provided above the ejection system 25, more specifically, above the ejection port 25c, as shown in the drawing, for example, it is provided on the back surface of the control board 33. The heat from the system 25 is easily received, and the temperature of the discharge system 25 is easily detected.
[0034]
Here, the upper surface of the control board 33 is mounted with hardware components such as the switches 48 and a display lamp (not shown), while the back surface of the control board 33 is mounted on a chip type microcomputer 33a or the like. By mounting the components on the surface and using the chip type thermistor as the ejection system sensor 72, both the component cost and the mounting cost can be reduced.
[0035]
In the example shown in FIG. 4, the heat conducting member 102 is sandwiched between the operation unit box 101 containing the control board 33 and the discharge port 25c. Thereby, the response performance of the discharge system sensor 72 to the temperature rise due to the discharge of the hot water content liquid 71 from the discharge port 25c of the discharge system 25 can be improved. It is preferable to use, for example, a silicon sheet for heat conduction as the heat conduction member 102. When a slightly thicker material is sandwiched by using elasticity, the operation unit box 101 and the discharge port 25c are not required without special molding. And to both.
[0036]
In the above method, the non-use time zone X ₁ ·································································· between Xm and the non-use time zone which is shorter than the predetermined value Y, as shown in the examples of FIGS. Normal warming time zone R from T hours before ₁ ··· Rn Thereby, the non-use time or the non-use time zone shorter than the predetermined value Y is the energy saving time zone Z. ₁ ..In order to perform normal heat retention without using Zn, normal heat retention time zone R from a predetermined time T before that ₁ ··· Rn, normal warming time zone R where the timing actually used at short time intervals is short ₁ .. It is possible to cope with a situation in which Rn deviates from time to time, and there is an advantage that the user is not dissatisfied or inconvenient. This corresponds to the shift to the front side, but the shift to the rear side can be similarly handled.
[0037]
This also means that, as shown in the examples of FIGS. 7B to 7D, the normal warming is performed a predetermined time T before the actual use point P. Energy saving time zone Z ₁ ..Insulation time zone R set from relationship with Zn ₁ .. If it overlaps with Rm, it can be ignored. In other words, energy saving time zone Z ₁ .. Means that Zn is shorter than the normal setting by a predetermined time T. As a result, the normal warming is performed for a predetermined time T before the actual use point P, so that the actual use point P becomes the energy saving time zone Z. ₁ ..At the time of switching from Zn to normal heat retention and in the normal heat retention time zone R ₁ ..In the case where Rn is short, the normal warm-up time zone R in which the timing actually used at short time intervals is short ₁ .. It is possible to cope with a situation in which Rn deviates from time to time, and there is an advantage that the user is not dissatisfied or inconvenient. This corresponds to the shift to the front side, but the shift to the rear side can be similarly handled.
[0038]
By the way, the progress of the actual use as described above can be easily and accurately determined by the electric signal relating to the ejection and the time management by the clock function and the calendar function. However, as described above, the product cost increases, and the user has to set the date and time in the early stage of use, which is inconvenient.
[0039]
Therefore, in the example of FIG. 7 and the example of FIG. ₁ ... Time measurement is started at the time of setting operation of Zn. Thereafter, based on the time measurement, actual use in a predetermined unit time range M, that is, the actual progress of the actual use time P for each elapsed time is shown in FIGS. The determination is made as shown in (a) to (c). The non-use time zone X in the example shown in FIG. 7A in the actual progress of the actual use time point P in the determined unit time range M for each elapsed time. ₁ ..X ₉ , The non-use time zone Z in the example shown in FIG. ₁ ..X ₁₂ Energy saving time zone Z as shown in FIGS. ₁ ..Use for setting of Zn. In the example of FIG. 7 (b), M = 1 day, T = 3 hours, and Z ₁ ..Z ₅ In the example of FIG. 7C, M = 1 day, T = 2 hours, and Z ₁ ..Z ₇ In the example of FIG. 7D, M = 1 day, T = 6 hours, and Z ₁ , Z ₂ In the example of FIG. 8D, M = 3 days and T = 3 hours. ₁ ..Z ₅ Is set.
[0040]
As a result, in the example of FIG. ₁ ..R ₄ In the example shown in FIG. ₁ ..R ₆ In the example shown in FIG. ₁ In the example shown in FIG. ₁ ..R ₈ It has become.
[0041]
Energy saving time zone Z ₁ After setting Zn, the energy-saving and heat-retaining operation is repeated when the energy-saving time zone for each set time elapses according to the elapse of the predetermined unit time range M based on the time measurement until the resetting time.
[0042]
In this way, energy saving time zone Z ₁ ..Because it is only necessary to start timekeeping when setting Zn, the clock function and calendar function are not required, realizing low cost, and eliminating the need for the user to set the date and time at the time of initial use. It will be easy to use. The actual progress of the actual use in the predetermined unit time range M from the time when the timing was started is calculated from the accumulation of the combination of the signal of the actual use thereafter and the information of the elapsed time until it is obtained, from the progress of the actual use. The non-use time zone X in the actual progress of the actual use in the unit time range M in the determined unit time range M ₁ ..Providing the energy-saving time zone for Xm, and when the energy-saving time zone for each elapsed time set according to the elapse of a predetermined unit time range based on the time measurement until the energy-saving time zone is reset, the energy-saving heat retention is performed. By performing the above, energy saving and heat keeping can be performed in accordance with the actual progress of the actual use of the user only by the elapsed time management without specifying the time by the clock function and the calendar function.
[0043]
In particular, by setting the predetermined unit time range M to be an integral multiple of 24 hours including one day shown in FIG. 7, no matter when the time measurement starts, the energy saving time zone Z set based on the elapsed time thereafter. ₁ ... The Zn pattern corresponds to the same time every day, and no shift occurs. Assuming that the elapsed time of 24 hours is one day and a plurality of days such as three days shown in FIG. 8, it is possible to more accurately determine the actual progress of the actual use of the user from the accumulated data of the plurality of days. It is possible to achieve this without a clock function and a calendar function only by managing the elapsed time based on the time measurement started at the time of setting the energy saving time zone.
[0044]
In order to achieve such a method, as the electric pot, as shown in FIG. ₁ .. It is sufficient to provide a timing means 77 for starting timing when setting the Zn. The timer 77 is also provided as an internal function of the microcomputer 33a, but is not limited to this. On the other hand, the actual use progress determining means 73 determines the actual progress of the actual use for each elapsed time in the predetermined unit time range M based on the time measurement by the time measuring means 77. Non-use time zone X in the actual progress by the actual use time in the unit time range M ₁ ..The energy saving time zone Z for Xn ₁ ..Set Zn and save energy Z ₁ ..The energy-saving time zone Z for each elapsed time set according to the elapse of time for each predetermined unit time range M based on the time measurement until the time point of resetting Zn ₁ .. When Zn is reached, energy saving and heat retention may be repeated.
[0045]
Energy saving time zone Z ₁ ... The time point for resetting Zn may be a predetermined time point or a time point when the discharge operation is performed a predetermined number of times or more during energy saving and heat keeping. Energy saving time zone Z at a given cycle ₁ ..Resetting Zn automatically changes the actual usage pattern of the user at regular timings expected from the difference between Weekday and Saturday and Sunday, and the difference in time, based on the elapsed time management. By resetting the energy saving time zone, it is possible to cope with a change that cannot be predicted if it is made at a short cycle point in a short time. In addition, when the discharge operation is performed a predetermined number of times or more during the energy-saving heat retention, the energy-saving time zone Z ₁ ..Resetting the Zn makes it possible to cope with the fact that does not match the actual situation regardless of the reason. ₁ ··························································· Energy saving time zone Z ₁ ················ Although the number of Zn setting operations may be small, the number of times of deviation from the actual usage of the user increases.

Here, an example of control by the microcomputer 33a of the present embodiment will be described. As shown in a main routine of main control in FIG. 9, after initialization is performed by turning on the power, input by various sensors and operations is performed. Output processing is performed. Next, display processing relating to input / output and accompanying operation control is performed. Subsequently, a boiling process for performing initial boiling and re-boiling, a normal heat retention at 98 degrees and 90 degrees, and a heat retention process for lowering the temperature and manually setting including heat stop and energy-saving heat retention at the settings are performed. Further, a discharge process by a discharge operation, an energy saving setting process for the automatic energy saving setting, and other processes are performed. Therefore, as long as there is no abnormal signal due to any abnormality and the power is not turned off, the processing after the input / output processing is repeated thereafter.
[0047]
As shown in FIG. 10, in the subroutine for performing the energy saving setting process, if there is an energy saving setting operation such as an operation of a dedicated key or a long press operation of another key such as the energy saving key 84, the energy saving setting flag is set to 0, and this is determined next. By doing so, the timer starts and the energy saving setting operation is performed automatically. Here, if the energy saving flag is set to 0 by the initial setting, it can be automatically performed at the beginning of use of the electric pot without any energy saving setting operation by a person. After the energy saving setting, the energy saving setting flag is set to 1, and the routine returns in the energy saving setting state until the energy saving setting flag is manually released by the energy saving setting operation or automatically released for a special reason.
[0048]
The energy saving setting process repeats storing the elapsed time in the storage means as the actual time point P actually used with the discharge of the hot water content liquid every time there is an electric signal related to the discharge at the same time as the start of the timing. With this repetition, it is determined whether a predetermined period such as date and time, week, month, season, etc. of the energy saving determination has elapsed from the timing result, and at the time, the discharge result stored in the storage means up to that time, that is, the actual use result progress From the energy saving time zone Z to be applied thereafter ₁ ... Zn is set by a process as shown in the energy saving time zone setting subroutine shown in FIG. 11 and the energy saving setting flag is set to 1. In the processing shown in FIG. 11, as described above, the non-use time zone X ₁ ..Only energy saving time zone Z in non-use time zone smaller than predetermined value Y of Xm ₁ ... Zn is set, and the energy saving time period is canceled before the time T before the actual use time, that is, the discharge time P, so that the energy saving time period is canceled and the energy saving time period is included in the normal heat insulation time period.
[0049]
As shown in FIG. 12, one or more energy saving time zones Z ₁ ..Determining whether or not the energy saving start time in Zn is based on the above timekeeping; otherwise, determine whether or not a manual operation of energy saving thermal insulation has been performed; otherwise, perform normal thermal insulation at the selected temperature. . When the energy-saving warming is manually operated, the set energy-saving warming is performed, but if there is a discharge during the energy-saving warming, the energy-saving warming is canceled, and the normal warming is returned. Set energy saving time zone Z ₁ When the energy saving start time of Zn is reached, the operation shifts to the energy saving and the heater 11 is turned off, so-called thermos bottle insulation is performed by the vacuum double container 3 as the heat insulating container, and the energy saving and the insulation is started. It decreases more than the case of heat retention. However, there is no rapid temperature drop due to the thermos thermal insulation, and the temperature can be maintained at about 60 to 70 ° C. in about 8 hours, although it varies depending on the amount of the content liquid 71 and the difference in the hot water temperature immediately before.
[0050]
At the end of the energy saving, since the temperature is lower than the normal warming temperature during the energy saving warming, a start-up process to the normal warming by a water heater mode or the like is performed, and then the normal warming is restored. However, this start-up process can be performed as a result of determining the content liquid temperature.
[0051]
If there is a discharge between the start of energy saving and the end of energy saving, apart from the re-execution control in the energy saving setting process, the startup process in the water heater mode etc. is performed as described above to return to normal heat retention, and the actual use by the discharge for the time being Corresponding to FIG. 14 shows such a control example and the temperature change of the content liquid in that case. Normal heat retention time zone R in which the set temperature in the normal heat retention heating mode is maintained ₁ Energy saving time zone Z ₁ Unused time zone R with ₁ To the next normal warming time zone R ₂ Heating is stopped until the thermos is completely insulated.
[0052]
However, as shown by the broken line in FIG. ₂ And continues to decrease until the start-up point in the heating mode of normal heat retention. For this reason, as shown in FIG. ₁ If the user performs a discharge operation in the middle of the process, the content liquid at a temperature lower than the set temperature in the normal heat retention is discharged, giving the user dissatisfaction, or performing a re-boiling operation for raising the temperature depending on the degree of dissatisfaction And inconvenience to the user. Therefore, such energy saving time zone Z ₁ If a discharge operation is performed during the heating operation, an early start-up to the set warming temperature in the water heater mode is performed, and the warming mode is set to the set warming temperature in the normal warming mode for a predetermined time t. It automatically responds to repeated use. The predetermined time t is preferably changed according to the number of ejections and the ejection amount at that time so that the ejection operation is not deviated.
[0053]
In addition, in the case of energy saving heat retention, it is preferable to light the energy saving lamp 93 and the evaporator heat retention display 110 regardless of manual setting or automatic setting. In the above-described startup, the temperature is being raised in a special mode by blinking the energy saving lamp 93 or the set temperature holding temperature 111 or the current temperature display 112 regardless of manual setting or automatic setting. It is convenient to be notified.
[0054]
As mentioned above, energy saving time zone Z ₁ If there is a discharge operation in the middle of Zn and start-up processing is performed, the current hot water temperature displayed on the liquid crystal display is flashed for a few seconds to notify it, or the set heat retaining temperature 111 and the energy saving lamp 93 are flashed. The user can be notified that the control is a special start-up process by notifying the user or operating the buzzer 100 times three times with the buzzer alone or three times.
[0055]
In addition, energy saving time zone Z ₁ ···························································································································································· The discharge lock is automatically set when there is no discharge for a certain period of time, and the lock release is performed prior to the discharge operation, so that the temperature rise for discharge can be started early.
[0056]
Further, when it is difficult to raise the temperature during the first halfway discharge, it is also possible to perform the start-up processing after the first discharge and keep the normal temperature for a predetermined time t.
[0057]
It is desirable from the viewpoint of energy saving that after the start-up process is performed by releasing the halfway ejection or the ejection lock and the normal temperature is kept for a predetermined time t, the halfway ejection is resumed and the energy is kept again. When returning to the energy-saving heat retention by stopping the discharge for a certain period of time or the like for a certain period of time, it is possible to correspond to the actual use during the process.
[0058]
In the control shown in FIG. ₁ ··············································· Sets the energy saving setting counter to +1 when there is a discharge operation in Zn, and sets the energy saving flag to 0 when the count reaches one or more predetermined times. As a result, the energy saving setting that no longer matches the actual situation is redone by the control shown in FIG. This resetting may be performed for the entire set energy saving time zone.However, the resetting is performed only for the specific energy saving time zone related to the actual use during such energy saving and warming. When the operation is performed for a number of energy saving time zones, the entire energy saving time zone that has already been set may be reset.
[0059]
Specifically, the discharge in the middle is in the energy saving time zone Z. ₁ .. It is conceivable to correct the corresponding time zone depending on which timing point in Zn. For example, when the timing point is near a boundary adjacent to the normal warming time zone in the corresponding energy saving time zone, the adjacent normal warming time zone is increased to the adjacent side so that the timing time point is included in the normal warming time zone. Then, the corresponding energy saving time zone is shortened on the adjacent side. In addition, energy saving time zone Z ₁ ..If the discharge timing of Zn is almost at the midpoint of the applicable energy saving time zone, the energy saving thermal insulation with the lower limit temperature set is set for the entire energy saving time zone or for a predetermined time in the middle, and the temperature is set to the set thermal insulation temperature. It is also possible to cope with the subsequent use by making the rise of the battery quicker.
[0060]
Alternatively, a predetermined time before and after the halfway discharge timing, for example, one hour, may be set as the normal heat retention time zone to cope with subsequent use.
[0061]
FIG. 13 shows the energy saving time zone Z which has been set by pressing and holding the energy saving key 84. ₁ .. Shows an example in which Zn can be changed. When the energy saving key 84 is pressed for a long time, the timer 1 is started to measure the time, and the energy saving lamp 93 is blinked to notify that the setting is being changed. At the same time, the current energy saving set time zone is displayed. Next, if the timer 1 has expired, the operation returns without operation continuation. If any of the up and down keys 88 and 89 has been operated without ending the timer 1, it is determined that the operation has been changed, and the timer 2 is started. At the same time, the start time or end time of the current energy saving time zone is displayed, and the displayed time is raised or lowered in accordance with the operation of the up / down keys 88 and 89. The display at this time is the elapsed time from the start of the predetermined time range T. However, when a clock function or a calendar function is used for energy saving setting, it can be displayed as time. Subsequently, when the timer 2 ends, the operation returns without the operation continuation, and when the energy saving key 84 is pressed and held without the timer 2 ending, the change operation ends and the set energy saving time zone is finally displayed. Time or time
Then, the blinking of the energy saving lamp 93 ends.
[0062]
FIG. 15 shows the energy saving time zone Z. ₁ .. Shows another setting method of Zn. The predetermined time range M is divided into a plurality of blocks M ₁ ··· Mn. Specifically, 24 blocks of 4 blocks each of 6 blocks M ₁ ..M ₆ Divided into Each block M ₁ ..M ₆ In the block M, where the discharge has occurred regardless of the day, ₁ , M ₃ , M ₅ , M ₆ For normal warming time zone R ₁ ..R ₃ , As the rest, energy saving time zone Z ₁ , Z ₂ Is set to According to this, the setting operation of the energy saving time zone is extremely simplified.
[0063]

[0065]
The lid 13 is formed with a vapor passage 17 for allowing the vapor from the vacuum double container 3 to escape to the outside, and is formed on an inner opening 17a of the lid 13 at a position facing the inside of the vacuum double container 3 and an outer surface exposed to the outside. It communicates with the outside opening 17b. In the middle of the steam passage 17, there is provided a safety path 17c for temporarily storing or bypassing the hot water content liquid 71 when the container 1 rolls over and enters the hot water storage liquid 71, and delaying reaching the outer opening 17b. . This makes it 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 to the outside. Further, in the steam passage 17, when the vessel 1 rolls over, a water stop valve 18 at the time of overturning which works by its own weight or the like so as to try to enter the steam passage 17 or to prevent the entered liquid from proceeding ahead is provided in an appropriate position. Is provided. In the illustrated embodiment, it is provided at one location just inside the inner opening 17a.
[0066]
A locking member 21 is provided at the front of the lid 13 to engage with the locking portion 19 on the shoulder 6 side at the closed position to lock the lid 13 at the closed position, and to lock the lid 13 when the lid 13 is closed. 19 is always projected to the lock position by the bias of the spring 22 so as to automatically engage with the lock member 19. Correspondingly, the lid 13 is provided with a lock release member 23 for releasing the lock by retreating the lock member 21. The lock release member 23 is a lever type pivotally supported by the lid 13 by a shaft 24 as shown in FIG. 1, and the front end 23a is depressed with a thumb or the like and rotated counterclockwise to spring the lock member 21 to a spring. The unlocked lid 13 can be lifted and opened by lifting the rear end 23b raised by the unlocking operation with another finger to retract the unlocked lid 13 by retracting it against the lock 22.
[0067]
In the space between the bottom of the outer case 2 and the bottom of the vacuum double container 3, a circuit box 28 accommodating a power supply / drive system board 27 is installed together with the electric pump 26. In the illustrated embodiment, the circuit box 28 is provided integrally with the opening at the bottom of the outer case 2. The circuit box 28 is provided with a lid 60 that opens downward and closes it.
[0068]
The upper part of the discharge system 25 constitutes a discharge port 25c, which is an inverted U-shaped unit, at a portion inserted between the projecting portion 31 of the container 1 and the pipe cover 2d on the outer case 2 side. The part 25c is provided with a water stop valve 34a when falling and a water stop valve 34b when leaning forward and a discharge port 25d. The discharge port 25d opens downward to the outside through the pipe cover 2d.
[0069]
A cover plate 36 is applied to the opening at the bottom of the outer case 2 from below by screwing or partially engaging, and a rotatable seat ring 37 is supported on the outer peripheral portion of the cover plate 36 so as to be rotatable. When the body 1 is fixed on a table surface or the like, it can be rotated slightly on the rotating seat ring 37 to change its direction.
[0070]
According to the operation panel 32 as described above, the discharge key 82 is always operated to discharge the hot water storage liquid 71, and the operation of the lock / release key 83 also indicates the intention to perform the next discharge operation. Therefore, the ejection operation should be performed with a probability of almost 100%, and in each case, an electric signal related to the ejection operation can be obtained. Further, even if the discharge is performed by the manual pump 10, if this is detected by a switch or a sensor, an electric signal of the discharge operation can be obtained.
[0071]
Therefore, the electric pot of the present embodiment is used as another energy-saving heat retention method, in which the hot water storage liquid 71 is supplied for use by the discharge operation while being kept at normal temperature or at a temperature lower than the normal temperature. The presence / absence of actual use is determined based on one operation signal related to the discharge of the content liquid 71, and a time zone suitable for energy saving is determined based on the lapsed record of the presence / absence of actual use and set as a subsequent energy saving time zone. Then, during the energy saving time period, the temperature is changed from the normal heat retention to the heat retention temperature.
[0072]
As described above, the presence / absence of actual use in which the hot water storage liquid 71 is discharged can be simply automatically determined by one operation signal relating to the discharge of the hot water storage liquid 71, and the determined actual use progress results It is possible to easily and accurately determine a time zone suitable for energy saving and heat retention from simple and small information related to the above. Therefore, a large capacity is not required to determine the energy saving time zone based on the progress of actual use over a longer period of time using a nonvolatile memory or the like, and the determination can be performed simply, so that the cost can be reduced. The time zone suitable for energy saving determined in this way is set as the subsequent energy saving time zone, and when the energy saving time zone is reached, the temperature is changed from the normal heat retention to the heat retention temperature. Is realized. The change of the heat retention temperature preferably includes a stop of heating corresponding to long-term nonuse, a temperature rising operation before returning to normal heat retention, and the like.
[0073]
Here, the above-described detection of the discharge temperature is performed by detecting a rapid temperature rise during a predetermined time, and the discharge of the hot-water content liquid 71 is performed by any temperature change shown in FIGS. 5 and 6. It can be detected reliably. In addition, this eliminates temperature data that does not show a peak as in the case where the temperature environment changes by carrying the electric pot, and eliminates the need to handle unnecessary data. As a specific example, the temperature detected by the discharge system sensor 72 starts to rise after a certain time lag after the actual discharge, and then shows a peak almost at the end of the discharge. Continuous. Therefore, while monitoring the temperature detected by the discharge system sensor 72, a timer for a predetermined time is started after detecting the lowest temperature, and during the period when the detected temperature rises to a predetermined temperature, for example, 3 ° C. or more, there is ejection, That is, it is determined that there is actual use. When this determination is made, the lowest temperature detection is reset for the next discharge determination, and the control is repeated. When the time is up without a predetermined temperature increase, it is determined that there is no ejection, the minimum temperature detection is reset for the next ejection determination, and the control is repeated.
[0074]
When the discharge is determined by the electric pump 26 and the discharge is determined by two signals of the signal relating to the discharge operation and the temperature detected by the discharge system sensor 72, the accuracy of the determination of actual use is improved. For example, in the case where a predetermined peak does not occur in the temperature detected by the discharge system sensor 72 in spite of the discharge operation signal, it is determined that the hot water storage liquid is insufficient or a malfunction has occurred and the user is notified by the notification unit. The electric pot itself and the safety in use can be improved by issuing an abnormal signal and stopping the control.
[0075]
Further, the discharge sensor 72 provided on the control board 33 monitors the detected temperature as the room temperature while the discharge temperature is not detected, and uses it for various controls such as hot water control of the hot water storage liquid, heat retention control, and liquid amount determination. be able to.
[0076]
【The invention's effect】
According to the present invention, the actual use signal accompanied by the discharge of the content liquid during the use state is an electric signal related to the discharge operation such as an electric discharge operation signal or a discharge operation signal that electrically detects the manual discharge operation. From the obtained actual use signal and the time information at the time of obtaining the signal, it is possible to simply determine the actual use progress. It is possible to easily and accurately set the target time zone for energy saving and heat keeping from the non-use time zone in the lapse of the actual use result determined simply, thereby achieving energy saving. Then, instead of setting all of the determined non-use time zones as energy-saving time zones, set the non-use time zones exceeding a predetermined value in the subsequent energy-saving time zones. Therefore, it is possible to eliminate the dissatisfaction and inconvenience given to the user side by performing energy-saving and heat-retaining at the time of non-use or non-use time when the device is repeatedly used at short time intervals such as eating and drinking.
[0077]
According to a further configuration, the non-use time or the non-use time zone shorter than the predetermined value is set to the normal warming time zone from a predetermined time before the start point.
The non-use time or non-use time period shorter than the predetermined value is not set as the energy saving time period, and the normal heat retention time zone is set before the predetermined time before performing the normal heat retention, so the timing of actual use at short time intervals is short. It is possible to cope with a case where the temperature deviates from the normal warm-up time zone occasionally, and there is an advantage that the user is not dissatisfied or inconvenienced. This corresponds to the shift to the front side, but the shift to the rear side can be similarly handled.
[0078]
In addition, according to a further configuration, the normal heat retention is performed a predetermined time before the actual use time.
By performing normal warming from a predetermined time before the actual use time, when the actual use time is a switching point from the energy saving time zone to the normal warming time and the normal warming time zone is short, a short time is used. It is possible to cope with a case where the actual use timing at the interval deviates from the normal warm-up time zone at that time, and there is an advantage that the user is not dissatisfied or inconvenienced. This corresponds to the shift to the front side, but the shift to the rear side can be similarly handled.
[0079]
In addition, the time measurement is started at the time of the setting operation of the energy saving time zone, and thereafter, based on the time measurement, the actual progress in the elapsed time of the actual use in the predetermined unit time range is determined, and the actual use in the determined unit time range is determined. Elapsed time set in accordance with the elapse of time for each predetermined unit time range based on the clock until the energy saving time zone is set for the non-use time zone in the actual progress of each elapsed time until the energy saving time zone is reset. According to a further configuration, the energy-saving heat retention is repeated at another energy-saving time.
Clocking can be started at the time of setting operation of the energy saving time zone, so that a clock function and a calendar function are not required, realizing at low cost, and eliminating the need for the user to set the date and time at the time of initial use, It will be easy to use. The actual progress of actual use in a predetermined unit time range from the start of timing is based on the accumulation of a combination of a signal of actual use thereafter and information on the elapsed time until it is obtained, from the elapsed time of actual use. It can be determined as another performance elapsed, and the energy saving time zone is set for the non-use time zone in the actual performance elapsed time according to the determined actual use time within the unit time range, and the energy saving time zone is reset. When the energy saving time zone is set according to the elapsed time set according to the time elapse of the predetermined unit time range based on the time counting up to the time, the energy saving and heat keeping is performed, and the elapsed time management without specifying the time by the clock function and the calendar function is performed. Energy conservation and heat keeping can be achieved in accordance with the actual progress of actual use by the user alone.
[0080]
According to a further configuration, the predetermined unit time range is a plurality of days in which 24 hours have elapsed as one day.
In order to more accurately judge the actual progress of actual use of users from accumulated data for multiple days, only the elapsed time management based on the time measurement started at the time of setting the energy saving time zone, there is no clock function or calendar function Can be achieved.
[0081]
According to a further configuration, the reset point of the energy saving time zone is a predetermined cycle point or a point in time when the discharge operation is performed a predetermined number of times or more during the energy saving heat retention.
If the energy saving time zone is reset at the predetermined cycle, the elapsed time management will be performed in response to changes in the user's actual usage pattern at regular timings expected due to differences between weekdays and weekends, differences in seasons, etc. This can be dealt with by automatically resetting the energy saving time zone based on the above, and it is possible to respond in a short term to a change that cannot be predicted if it is performed at a short period. In addition, if the energy saving time zone is reset when the number of discharge operations is equal to or more than a predetermined number of times during the energy saving warming, it is possible to respond to the fact that does not match the actual situation regardless of the reason, and the accuracy increases when the number of predetermined times is reduced. However, if the number of energy saving time zone setting operations increases and the predetermined number is increased, the number of energy saving time zone setting operations may be small, but the number of deviations from the actual usage of the user increases.
