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 in which power supply is not required. In addition, energy saving heat retention is performed in all the time periods in which the determined energization does not need to be performed.
[0005]
[Problems to be solved by the invention]
However, the power information at the time of power supply to the main body, which is detected and stored by Patent Document 1, includes power supply information for initial water heating and normal heat retention, and has a large amount of stored information. Complicated operations are required to grasp the actual state of use, and accurate determination is difficult. In particular, if a user's usage pattern is to be more correctly grasped from long-term accumulated data in a non-volatile memory or the like, the accumulated data will increase and the actual situation of use will be more difficult to grasp.
[0006]
In order to solve this, the present inventor has conducted various experiments and studied repeatedly, and in the energy saving control of electric pots, it is easy to judge that the actual use is performed by discharging the content liquid, It was found that it was reasonable from the certainty of the judgment.
[0007]
On the other hand, it is often used repeatedly during eating and drinking meals, but is rarely used repeatedly at midnight or the like. For this reason, the energy saving effect is reduced if the normal warming is performed even during use during a time when the frequency of use is almost infrequent, such as that described in Patent Document 1. Also, if you keep energy-saving heat even during short non-use times during frequent repetitive use during meals, rather than waste, the temperature of the hot water drops before the next use and it is not intended for use that is sensitive to temperature such as tea and coffee. Depending on the degree of dissatisfaction, it is easy for the user to be dissatisfied, and a special operation for re-boiling to recover the hot water temperature or starting up to the set warming temperature and a waiting time are required, which inconveniences the user. .
[0008]
SUMMARY OF THE INVENTION An object of the present invention is to provide an energy-saving and heat-insulating method that is less wasteful and less likely to cause dissatisfaction and inconvenience to a user by a simple determination operation based on the above-described new findings, and an electric hot water storage container to which the method is applied. .
[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, the actual use results are determined for each time period corresponding to each of a plurality of time blocks obtained by dividing the time length of one day unit, and the time period of the time block having the predetermined actual use results is determined. The following is the normal heat-retention time zone, and the time between the time blocks in which there is no actual record of actual use is the subsequent energy-saving time zone. When it comes to energy saving, it is characterized by keeping it warm.
[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 when it was obtained, the actual use belongs to which time block corresponding to each time block obtained by dividing the time length by one day. Specify. As a result, it is possible to easily and at low cost determine the actual use results for each time block corresponding to each time block without omission. Therefore, a time interval in a time block having a predetermined actual use result is a normal heat retention time zone thereafter, and a time interval in a time block having no predetermined actual use time is a subsequent energy saving time zone. The feature that the time block can be specified by the time makes it easy to achieve accurate energy saving and heat keeping in accordance with the pattern of daily life and actual use, and it is possible to avoid dissatisfaction and inconvenience to the user.
[0011]
For this purpose, it is preferable that the reference value of the number of times of actual use for judging the actual performance of the predetermined actual use be different depending on which time block.
[0012]
As an electric hot water storage container that achieves the above-described method, the content liquid is heated by a heater so as to be used by a discharge operation while continuing to use while maintaining normal heat or energy saving at a temperature lower than normal heat. In the electric hot water storage container as described above, the clock means and the time length of each day in the time measured by the clock means are divided and used for each time interval corresponding to each of a plurality of set time blocks. For the time interval of a time block having a predetermined actual use record, a time interval of a time block having no predetermined actual use record is set. Energy-saving and heat-retaining control means for setting the subsequent energy-saving time period, performing normal heat-retention at the time of the normal heat-retention time period, and performing energy-saving and heat-retention at the time of the energy-saving time period. Enough in what the.
[0013]
In the above method, in particular, in a further configuration, the actual use count reference value during meal is lower than the count reference value in other time blocks such as midnight,
Although it is a time block that includes meals, the number of times of actual use is small, so it is usually set as an energy saving time zone. It is assumed that the actual use pattern and life pattern at the time of eating are not different from the general, by setting the normal warming side to the normal warming time zone with high priority on the normal warming side and setting it to the energy saving time zone It is possible to avoid dissatisfaction and inconvenience to the user, and to set the energy saving time zone just because it was actually used multiple times in the time block outside the meal, If the number of times of use does not exceed the number of actual uses that is higher than the case of meals, it does not differ from the actual use pattern and life pattern during non-meal time, high priority on energy conservation and heat retention side In set energy saving time period, energy saving effect unnecessarily setting the normal incubation time period can be prevented, such as drops.
[0014]
To achieve this, it is effective for the electric hot water storage container to determine a predetermined actual use result based on an actual use reference value set differently for each time block by the energy-saving heat retention control means, The actual use reference value can be set automatically or manually.
[0015]
Further, in the above method, in a further configuration in which the time length is different depending on which time block,
It is possible to set and execute a more accurate normal warming time zone and an energy saving time zone corresponding to a difference in a time interval in which a common pattern of actual use continues. Even at the same meal, for example, it is possible to suitably cope with, for example, a short length at breakfast, a long length at dinner, and an intermediate length at lunch.
[0016]
In a further configuration, the time length of the meal time block is shorter than the midnight time block,
Even if the time length at the time of a meal is the longest at the time of a dinner, it is possible to suitably cope with a case where comparison is not possible with a late-night time block in which the frequency of use is extremely low.
[0017]
In a further configuration, the actual use reference value for determining the performance of a given actual use differs depending on which week or time period and seasonal time block.
It is possible to suitably cope with a case in which the user's daily usage pattern varies depending on the day of the week, a specific period such as a long vacation, or a season such as spring, summer, autumn and winter. In this case, it is preferable to use a calendar function for the clock function.
[0018]
In addition, in a further configuration, a time block is provided for continuing normal warming without a predetermined actual use record.
For example, in general, dinner is usually from 18:00 to 20:00 at dinner, so that it is possible to deal with normal warming without special determination. If this does not match the usage pattern or life pattern of the user, there is no particular problem because the setting can be automatically reset and the setting can be changed by the operation of the user.
[0019]
In addition, in a further configuration, a time block for energy-saving heat retention is provided even if there is a predetermined actual use record.
For example, in general, 2:00 to 4:00 is most likely to be bedtime, so that it can be handled as normal warming without special determination. If this does not match the usage pattern or life pattern of the user, there is no particular problem because the setting can be automatically reset and the setting can be changed by the operation of the user.
[0020]
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.
[0021]
【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.
[0022]
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 29 for detecting the temperature of the content liquid for water heating, normal temperature keeping, and energy saving keeping. The content liquid temperature detecting means 29 is an inner container sensor 29 individually applied to the center of the single bottom of the vacuum double container 3 serving as an inner container to which the heater 11 is applied.
[0023]
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 hot water supply notification lamp 92, an energy saving lamp 93, and the like are provided using LEDs or the like.
[0024]
The electric pot serving as the electric hot water storage container of the present embodiment is, as an energy saving heat retaining method, first discharges the hot water content liquid 71 continuously while keeping the energy saving at a normal temperature or at a temperature lower than the normal temperature. A plurality of time blocks B obtained by dividing a time length of 24 hours per day for actual use by operation. ₁ To Bm, four time blocks B in the schematic example shown in FIG. ₁ ~ B ₄ Time interval t corresponding to ₁ ~ T ₂ , T ₂ ~ T ₃ , T ₃ ~ T ₄ , T ₄ ~ T ₁ The result of the actual use P for which the ejection operation has been performed is determined every time. The determination is based on the results for three days shown in (a) to (c) shown in FIG. ₁ ~ B ₄ It is determined as the cumulative result of each. The determination is made when one day has passed, but the greater the number of accumulations, the better the determination accuracy. Next, each determined time block B ₁ ~ B ₄ , A time block B having a predetermined actual use result S, and in the example of FIG. ₁ , B ₂ , B ₃ The normal warming time zone R ₁ , R ₂ , R ₃ The time block B in which there is no predetermined actual use record, B in the example of FIG. ₄ Energy saving time zone Z ₁ And normal heat retention time zone R ₁ , R ₂ , R ₃ At the time of the normal heat retention, energy saving time zone Z ₁ When the time comes, energy saving and warming is performed.
[0025]
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.
[0026]
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 in 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 in 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.
[0027]
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 signal of the actual use P can be reliably obtained by one electric signal relating to the ejection, regardless of whether the container 1 is tilted.
[0028]
Each time block B obtained by dividing the time length in units of one day from the signal of the actual use P obtained in this way and the time information at the time of obtaining the signal P ₁ ~ B ₄ The time period corresponding to the actual use is identified. Thus, each time block B ₁ ~ B ₄ Time interval t corresponding to ₁ ~ T ₂ , T ₂ ~ T ₃ , T ₃ ~ T ₄ , T ₄ ~ T ₁ It is possible to easily and at low cost judge the actual use results for each of the cases. In this case, as described above, even if data for several days of actual use P is stored in the non-volatile memory and determined, the amount of data to be handled is small, so that the capacity may be small. It does not cause.
[0029]
Therefore, each time block B ₁ ~ B ₄ Each time block B with a predetermined actual use record S in ₁ ~ B ₃ Time t at ₁ ~ T ₂ , T ₂ ~ T ₃ , T ₃ ~ T ₄ For the following normal warming time zone R ₁ ~ R ₃ And time block B for which there is no actual use record ₄ Time t ₄ ~ T ₁ About energy saving time zone Z ₁ And thereafter, each time block B ₁ ~ B ₄ Can be specified by the time of day, it is easy to achieve accurate energy saving and heat keeping in accordance with the pattern of daily life and actual use, and it is possible to avoid dissatisfaction and inconvenience to the user. In addition, energy saving and warming can be performed during a short period of time during which actual use is repeated at short intervals such as when eating and drinking, so that discomfort and inconvenience to the user can be avoided. Even if there is, it is possible to avoid the occurrence of waste due to performing normal heat retention based on actual use in a time zone that is hardly repeated.
[0030]
The energy saving heat retention in the energy saving time zone Z is, for example, sufficiently lower than the set temperature in the normal heat insulation in consideration of the effect on actual use in the next normal heat retention time zone R, but is set to a slightly higher energy saving heat retention temperature, or The heater 11 is turned off and the heating is stopped. In order to conserve energy as the thermos is kept warm, near the return to the normal heat preservation, the temperature is raised to a predetermined temperature in a water heating mode or the like for the next use, for example, a set heat preservation temperature. By using the presence or absence of a predetermined actual use result S such as eliminating inconvenience of use, there is no inconvenience in use and it is possible to set a heat retaining state advantageous for energy saving.
[0031]
In order to achieve the above-described method, the hot water storage liquid 71 is heated by the heater 11 so as to maintain the normal use or the energy saving at a temperature lower than the normal heat while maintaining the use state for use by the discharge operation. The electric pot of the present embodiment as described above divides a clock unit 77 and a time length of 24 hours per day in the time measured by the clock unit 77 into a plurality of set time blocks B. ₁ Time interval t corresponding to ~ Bm ₁ ~ T ₂ , T ₂ ~ T ₃ , T ₃ ~ T ₄ , T ₄ ~ T ₁ A performance determining means 73 for determining the performance of the actual use P for each time, and a time block B (B in the schematic example) having a predetermined performance S of the actual use. ₁ ~ B ₃ ), The subsequent normal heat retention time zone R (R in the schematic example) ₁ ~ R ₃ ), And a time block B without a predetermined actual use record S (in the schematic example, B ₄ ), The subsequent energy saving time zone Z (in the schematic example, Z ₁ ), It is sufficient to provide energy-saving heat-retaining control means 74 for performing normal heat-retaining at the time of the normal heat-retaining time zone R and for energy-saving and heat-retaining at the time of the energy-saving time zone Z. In other words, it is preferable to provide the storage unit 75 for storing information on the time when the actual use P occurred, and to provide the control of the energy saving and heat keeping control unit 74. Further, in order to accumulate data for several days, the power may be turned off due to replacement or washing of the liquid in the middle. Therefore, in order to cope with this, a non-volatile memory such as having a backup power supply 76 is used. It is preferable to adopt as In particular, in addition to the several-day cycle, one-week cycle, several-week cycle, one-month cycle, several-month cycle, actual use of the user from long-term stored data through the four-season cycle, or usage pattern, life pattern Can be easily and accurately determined and responded to. In order to cope with the pattern cycle for each day of the week or more, it is preferable to employ a calendar function as the clock means 77.
[0032]
Note that 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 the vicinity thereof, for example, provided at a position as shown in FIG. The energy saving and heat keeping control means 74 and the clock means 77 can be constituted by a single circuit or device, respectively, or by 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.
[0033]
Here, the predetermined actual use result S is effective if it is determined whether or not the number-of-times reference value N of the actual use P is equal to or greater than a predetermined value. In the schematic example of FIG. 7, N = 2. Time block B ₁ Then N = 4, B ₂ Then N = 4, B ₃ In this case, N = 10, and N ≧ 2 in both cases. ₁ ~ R ₃ And set time block B ₄ Since N = 1 and N <2, the energy saving time zone Z ₁ Has been set.
[0034]
In such a schematic example, while the actual use P or the actual use pattern or the pattern can be derived by judging the actual use P, the N value is set, and the sleeping time zone in the normal life pattern expected from the recognition of the time is set by the N value setting. In the time block B, a rare ejection operation is treated as irregular, so that it is difficult to set the normal heat retention time zone R, and it is easy to set the energy saving time zone Z. In block B, taking advantage of the fact that the ejection operation is likely to be repeated, it is easy to set the normal heat retention time zone R, and it is difficult to set the energy saving time zone Z, so as to suitably respond to the user's daily life pattern. Energy saving without dissatisfaction or inconvenience to the user.
[0035]
In particular, the number-of-times reference value N for actual use during a meal can be set lower than the number-of-times reference value N for other time blocks such as midnight. For example, time block B including meal time ₁ ~ B ₃ Value of N at 2, time block B not including meal time ₄ If the N value of is 3, the time block B including the meal time ₁ ~ B ₃ However, since the number of times of actual use is as small as two times, it is usually set in the energy saving time zone Z. By setting N ≧ 2, even when the number of times of actual use is small, it includes the time of eating. It is assumed that the actual use pattern and the life pattern at the time of eating are not different from the general ones, which are actually used during the time period. It is possible to avoid giving the user dissatisfaction and inconvenience by setting Z. In addition, time block B which is off meal time ₄ However, N <= 3, where the energy saving time zone is set to win even if the actual use is repeated a plurality of times. Assuming that the usage pattern and life pattern are not different, the energy saving time zone Z is set with a high priority on the energy saving and warming side, and the normal energy saving time zone R is set unnecessarily to reduce the energy saving effect. Can be prevented.
[0036]
However, instead of this, for example, a time block B including a meal time ₁ ~ B ₃ N value of 3 or more, other time block time block B ₄ If the value of N in is set to an inverse relationship of 2 or more, the time block B including the time of meal is the same as in the above case. ₁ ~ B ₃ Normal warming time zone R per ₁ ~ R ₃ Is set and the time block not including the meal time block B ₄ Energy saving time zone Z ₁ And the same effect can be obtained. However, time block B including meal time ₁ ~ B ₃ However, if it is not actually used enough to keep the temperature normal, it is determined based on whether the N value is less than 3, and in such a case, the energy saving time zone is set, and if the N-value is used irregularly, boiling or It is possible to perform control that gives priority to energy saving by using the apparatus with a start-up operation to the set warming temperature. Time block B not including meal time ₄ Even in the case where it is convenient for the user to keep the normal heat, it is determined whether or not the N value exceeds 2, and in such a case, the normal heat-retention time zone is set, and the user's unique actual temperature is set. It is suitable because it can be adapted to use patterns and life patterns.
[0037]
In order to achieve this, the energy-saving and heat-retaining control means 74 sets the time block B ₁ ~ B ₄ The presence / absence of a predetermined actual use result S is determined based on the actual use count reference value N set differently depending on the actual use count, and the actual use count reference value N is automatically or manually set. Can be.
[0038]
However, in the example shown in FIG. 8, data of the actual use P for three days is accumulated and N = S is uniformly set, and if there is one actual use P, it is determined that there is a predetermined actual use result S. I have to. Therefore, each set time block B ₁ If the actual use P is at least once for each time block B from Bm to Bm, the result is set to the normal heat retention time zone R as the predetermined actual use result S, otherwise, the energy saving time zone Z is set. The setting operation can be simplified and realized at the lowest cost. In addition, the time for one day is divided into six time blocks B ₁ ~ B ₆ Is set more than in the above-mentioned model example, and the greater the number of time blocks, the easier it is to match the actual use pattern and life pattern of the user. In this example, it is sufficient that one time block B has one actual use P, and a plurality of times can be handled as one time. Therefore, if there is one actual use P, the subsequent operation of capturing the actual use P can be omitted in the time block B.
[0039]
The ejection system sensor 72 as the ejection system temperature detecting means is mounted on a control board 33 as an existing circuit board near the ejection 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.
[0040]
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.
[0041]
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. Since the heat from the system 25 is easily received, the temperature of the discharge system 25 can be more easily detected.
[0042]
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.
[0043]
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.
[0044]
In the above method, if the number-of-times reference value N of the actual use P for determining the predetermined actual use result S is made different in which time block B, it is difficult to set the normal heat retention time zone R as described above. In each time block B, an operation to make it easy to set for the energy saving time zone Z or to make it easy to set for the normal heat retention time zone R and to make it difficult to set it for the energy saving time zone. ₁ ~ B ₄ Corresponding time t for each ₁ ~ T ₂ , T ₂ ~ T ₃ , T ₃ ~ T ₄ , T ₄ ~ T ₁ Can be executed in accordance with the characteristics of the pattern of the actual use P expected from As described above, the number-of-times reference value N of the actual use P is effective by being manually set based on the expected user's life pattern, but the time during which the ejection operation is rare and irregularly treated is determined from the cumulative result of the actual use P actual pattern. It is also possible to determine a block B and a time block B in which the ejection operation is frequently repeated, and automatically set an N value necessary for the time block B.
[0045]
Further, in the above method, the time length, that is, the time length can be made different depending on which time block B. As a result, it is possible to set and execute the more accurate normal warming time zone R and the energy saving time zone Z corresponding to the difference in the time interval at which the common pattern of the actual use P continues. Even at the same meal, for example, it is possible to suitably cope with, for example, a short length at breakfast, a long length at dinner, and an intermediate length at lunch.
[0046]
Therefore, as shown in FIG. ₁ , B ₃ , B ₅ Time length is midnight time block B ₆ If it is set to be shorter than that, the time length at the time of meal is the longest at the time of dinner, but the use frequency is extremely low. ₆ Can not be compared.
[0047]
In the schematic example shown in FIG. 9, in particular, 24 hours for one day are divided into six time blocks B. ₁ ~ B ₆ The meals are generally divided into three times: morning, noon, and evening. In addition, the morning and noon meals are shorter than the dinner time, and the morning meals are lunch time. Time block B for breakfast to match the general trend that the time zone is shorter than ₁ Then the time t ₁ ~ T ₂ For 2 hours from 6:00 to 8:00, lunch time block B ₃ Then the time t ₃ ~ T ₄ 3 hours from 11:00 to 14:00, time block B at dinner ₅ Is set to 4 hours from 18:00 to 22:00, and the length is added to each. On the other hand, time block B in the late night time zone ₆ Is set the longest at 22:00 to 6:00. In addition, the remaining time block B ₂ , B ₄ Is between the remaining times. As a result, the same number of time blocks B as in the case shown in FIG. ₁ ~ B ₆ Although the setting is the same, a time block B having a length corresponding to the degree of the same actual use pattern and life pattern that is specified or expected by the recognition of the time is used. The band Z can be automatically set.
[0048]
The number-of-times reference value N of the actual use P for determining the predetermined actual use result S may be different depending on which week, time, or seasonal time block. Accordingly, it is possible to suitably cope with a case in which the user's daily usage pattern varies depending on the day of the week, a specific time such as a long vacation, or a season such as spring, summer, autumn and winter. In this case, it is preferable to use a calendar function for the clock function.
[0049]
Note that even four time blocks B are effective as described above, and the accuracy of the determination of the predetermined actual use result S increases as the number of time blocks B increases. However, the patterns of actual use patterns and daily life patterns that are repeated every day are not so many. Therefore, in general households, six or eight as shown in FIG. 9 can be sufficiently handled, and the number of families is large. Even if there is a family whose actual use pattern or life pattern is shifted or different, about 15 can sufficiently cope with it. Therefore, the number of divisions of the time block B may be about 4 to 15.
[0050]
If the time block B is long, the determination result covers the entirety, so that it tends 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, so it is preferable to make corrections according to the actual use. . In addition, when the results S for a plurality of days are to be determined, a normal heat retention time zone R is set based on the results S for one day by using the fact that there is not much change every day at meal time, and irregular use is performed at midnight. By using the fact that is the majority, the normal heat retention time zone is not set unless the results S for a plurality of days overlap. Further, in the example of FIG. 7, if there is a plurality of actual uses P in the same time block B, the count is counted. Therefore, if a plurality of actual uses on the same day are handled as one time, and if the actual use is determined over a plurality of days and the result S is set as the normal heat retention time zone R, it is easy to match the actual situation.
[0051]
It should be noted that a time block in which normal heat retention is continued even when there is no predetermined actual use record may be provided. In this case, for example, since dinner usually occurs at 18:00 to 20:00 in most cases, it can be handled as normal warming without special determination. If this does not match the usage pattern or life pattern of the user, there is no particular problem because the setting can be automatically reset and the setting can be changed by the operation of the user.
[0052]
In addition, a time block for performing energy-saving and heat-retaining can be provided even if there is a predetermined actual use record. By doing so, for example, generally from 2:00 to 4:00, most of the time it is at bedtime, it can be handled as normal warming without special determination. If this does not match the usage pattern or life pattern of the user, there is no particular problem because the setting can be automatically reset and the setting can be changed by the operation of the user.
[0053]
Here, an example of control by the microcomputer 33a according to the present embodiment will be described. As shown in a main routine of main control in FIG. 10, 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.
[0054]
As shown in FIG. 11, 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. Then, the clock unit 77 starts to capture the time measured by the clock unit 77 and automatically performs the energy saving setting operation. 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.
[0055]
The energy saving setting process repeats storing the current time in the storage unit whenever the electric signal related to the discharge is present and whenever there is the actual use P accompanied by the discharge of the hot water storage liquid, in conjunction with the start of the reading of the timekeeping time. With this repetition, it is determined whether or not a predetermined date and time such as date and time, week, month and season of the energy saving determination have passed. 12 is determined for each time block B that has been initially set or manually set, and the energy saving time zone Z shown in FIG. This is set by the processing shown in the subroutine, and the energy saving setting flag is set to 1.
[0056]
In the processing shown in FIG. 12, first, the current time block B is determined and the time block B ₁ ＢBm to the control flow of the corresponding time block B. Time block B ₁ The number of times of actual use P from the start time to the end time is counted, and the time block B ₁ Reference number N of actual use corresponding to ₁ It is determined whether or not the time block B has been reached. ₁ Is set to the energy saving time zone Z. If it has reached, the normal heat retention time zone R is handled by the heat retention control. If the predetermined date and time is a plurality of days, the count is repeated at the corresponding time until the end of the count, so that the judgment can be made based on the cumulative result exceeding the day unit. However, the specific setting operation can be performed in any manner.
[0057]
As shown in FIG. 13, one or more energy saving time zones Z ₁ It is determined whether or not it is the energy saving start time in Zn based on the time measurement, otherwise, it is determined whether or not a manual operation of energy saving heat retention has been performed, and otherwise, the temperature selected as the normal heat retention time zone R Perform normal warming in 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 in Zn is reached, the operation shifts to energy-saving heat retention, the heater 11 is turned off, so-called thermos bottle insulation is performed by the vacuum double container 3 serving as an insulated container, and energy-saving heat insulation is started. It decreases more than the case of heat retention. However, there is no sharp drop in temperature due to the thermos bottle keeping, and the temperature can be maintained at about 60 to 70 ° C. in about 8 hours, depending on the amount of the hot water content liquid 71 and the difference in the hot water temperature immediately before. .
[0058]
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.
[0059]
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.
[0060]
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.
[0061]
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. Also, in the above-mentioned start-up, if the energy saving lamp 93 or the set temperature display 111 or the current temperature display 112 is blinked irrespective of manual setting or automatic setting, the temperature is being raised in a special mode. It is convenient to be notified.
[0062]
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 temperature display 111 flashes and the energy saving lamp 93 flashes. 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.
[0063]
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.
[0064]
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.
[0065]
It is desirable from the viewpoint of energy saving that after the start-up processing is performed by releasing the halfway discharge or the discharge lock, and the normal temperature is kept for a predetermined time t, the halfway discharge 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.
[0066]
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 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.
[0067]
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.

【The invention's effect】
According to the present invention, the actual use signal accompanying 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 when it was obtained, the actual use belongs to which time block corresponding to each time block obtained by dividing the time length by one day. Specify. As a result, it is possible to easily and at low cost determine the actual use results for each time block corresponding to each time block without omission. Therefore, a time interval in a time block having a predetermined actual use result is a normal heat retention time zone thereafter, and a time interval in a time block having no predetermined actual use time is a subsequent energy saving time zone. The feature that the time block can be specified by the time makes it easy to achieve accurate energy saving and heat keeping in accordance with the pattern of daily life and actual use, and it is possible to avoid dissatisfaction and inconvenience to the user.
[0077]
For this purpose, it is preferable that the reference value of the number of times of actual use for judging the actual performance of the predetermined actual use be different depending on which time block.
[0078]
According to a further configuration, the frequency reference value of actual use during meal is lower than the frequency reference value of other time blocks such as midnight,
Although it is a time block that includes meals, the number of times of actual use is small, so it is usually set as an energy saving time zone. It is assumed that the actual use pattern and life pattern at the time of eating are not different from the general, by setting the normal warming side to the normal warming time zone with high priority on the normal warming side and setting it to the energy saving time zone It is possible to avoid dissatisfaction and inconvenience to the user, and to set the energy saving time zone just because it was actually used multiple times in the time block outside the meal, If the number of times of use does not exceed the number of actual uses that is higher than the case of meals, the actual use pattern and life pattern during the non-meal time period will not be different, high priority on the energy saving and warming side In set energy saving time period, energy saving effect unnecessarily setting the normal incubation time period can be prevented, such as drops.
[0079]
Further, according to a further configuration in which the time length is different depending on which time block,
It is possible to set and execute a more accurate normal warming time zone and an energy saving time zone corresponding to a difference in a time interval in which a common pattern of actual use continues. Even at the same meal, for example, it is possible to suitably cope with, for example, a short length at breakfast, a long length at dinner, and an intermediate length at lunch.
[0080]
According to a further configuration, the time length of the meal time block is shorter than the late night time block,
Even if the time length at the time of a meal is the longest at the time of a dinner, it is possible to suitably cope with a case where comparison is not possible with a late-night time block in which the frequency of use is extremely low.
[0081]
According to a further configuration, the actual use reference value for determining the performance of a given actual use differs depending on which week or time, and seasonal time block.
It is possible to suitably cope with a case in which the user's daily usage pattern varies depending on the day of the week, a specific period such as a long vacation, or a season such as spring, summer, autumn and winter. In this case, it is preferable to use a calendar function for the clock function.
[0082]
In addition, according to a further configuration, a time block is provided for continuing normal warming without a predetermined actual use record.
For example, in general, dinner is usually from 18:00 to 20:00 at dinner, so that it is possible to deal with normal warming without special determination. If this does not match the usage pattern or life pattern of the user, there is no particular problem because the setting can be automatically reset and the setting can be changed by the operation of the user.
[0083]
In addition, according to a further configuration, a time block for performing energy-saving heat retention even when there is a predetermined actual use record is provided.
For example, in general, 2:00 to 4:00 is most likely to be bedtime, so that it can be handled as normal warming without special determination. If this does not match the usage pattern or life pattern of the user, there is no particular problem because the setting can be automatically reset and the setting can be changed by the operation of the user.
