Description

  The present invention relates to an energy usage display device, and more particularly, a home such as a condominium or a detached house such as a condominium, or a facility such as a shower room of a sports gym or a hotel bathroom (hereinafter referred to as “home etc.”). It is related with the display apparatus provided with the function which displays the target value about the usage-amounts, such as energy, such as gas used, water, and electricity.

  Recently, a remote controller of a hot water supply device used at home or the like has a function of displaying the amount of gas or water used in the hot water supply device on a display unit.

  With this type of remote control, the integrated value of gas and water usage over a certain period in the past is obtained, and the target value for gas and water usage is calculated and set based on this integrated value. For example, Japanese Patent Application Laid-Open No. H10-260826 has been proposed. That is, there has been proposed an apparatus that arouses the user's energy conservation awareness by displaying a target value of the amount of gas, water, etc. used on the remote controller.

JP 2011-179810 A

  However, as shown in Patent Document 1, the method of setting the target value from the integrated value of the usage amount in the past certain period has the following problems, and improvement has been desired.

  That is, in such a method, if there is a period during which the user is absent due to travel, for example, during a certain period in which the usage amount is accumulated, gas and water are not used during that period. Although the target value is calculated and set based on the integrated value even with such a small integrated value, the target value becomes an extremely small numerical value that is far from the actual life. There is an inconvenience that the user cannot refer to the target value displayed in the section.

  The present invention has been made in view of such problems, and an object of the present invention is to set and display an appropriate target value even when a period of absence during travel or the like is interposed. An object of the present invention is to provide a display device for energy consumption.

To achieve the above object, utilization display device such as the energy of the present invention, gas, water, a display device for displaying the amount of energy or the like used in an electric household or facility, a plurality of types For each energy, etc., a calculation unit that totals the amount used in a predetermined unit period, and a calculation that calculates the target value per unit period from the total value obtained by integrating the totals collected by the totaling unit for a certain number of times. And a display unit that displays the calculation result of the calculation unit as the target value, the calculation unit excludes, from the integration target, the total results that do not satisfy the predetermined condition when calculating the target value. and a control arrangement for calculating a target value, and, in cases where not satisfy the predetermined condition for such any one of the energy of such as the energy, the predetermined condition Also counting result such as all other energy is aggregated total result the same period not Tasa characterized in that it comprises the excluded control structure from the accrual.

  The predetermined condition is that the total result is equal to or greater than a predetermined threshold value, or that the total result is equal to or greater than a predetermined ratio with respect to the past target value or the past total result.

  That is, the energy usage amount display device of the present invention displays the target value of the energy usage amount used at home such as gas, water, electricity, etc. on the display unit. 1 day as a unit period, the daily usage is totaled by the totaling unit, and the totaling results obtained by this totaling unit are totaled a certain number of times (for example, 14 days) by the arithmetic unit, The target value per day is calculated on average. That is, the calculation of the target value is performed for each type of energy such as gas and water, and the display of the target value is also displayed for each type. Here, “energy etc.” is used as a general term for resources and energy consumed in homes such as gas, water and electricity.

  In the present invention, in the integration in the calculation unit, the totaling result of the totaling unit is less than a predetermined threshold or less than a predetermined ratio with respect to a target value (or past totaling result) calculated in the past, and does not satisfy the predetermined condition In this case, the total result is excluded from the target of the target value calculation. That is, in this case, the calculation unit calculates the target value by integrating the total results for 14 days excluding the total results excluded from the integration targets.

  In addition, for example, when the totaling result totaled by the totaling unit does not satisfy the predetermined condition for two consecutive days, this two-day totaling result is excluded from the integration target, and the totaling results for the other 14 days are integrated. To calculate the target value.

Therefore, according to the present invention, when there is a day when gas, water, or the like is not used (or extremely few even if used), the above-mentioned predetermined condition is not satisfied during the absence, according to the present invention. In other words, since it is excluded from the target of the target value calculation, the target value displayed on the display unit is in line with the actual life (life excluding the absence period), and an appropriate numerical target is set as the target value. Set and display.
Further, in the present invention, when any one of the energies etc. does not satisfy the predetermined condition, all the other enumerated in the same period as the aggregation result not satisfying the predetermined condition Because it has a control configuration that excludes the total results of energy, etc. from the above accumulation targets, the total results of gas and water that show a significant decrease in usage when they are absent due to travel etc. are excluded from the accumulation targets In the case of energy, etc., such as electricity, where the decrease in the aggregated result is not likely to appear significantly, the aggregated result for that unit period is excluded from the integration target, so target values such as electricity are also set and displayed appropriately. Will be able to.

  Further, as a preferred embodiment of the present invention, in addition to counting within the unit period, the counting unit uses energy or the like in the second unit period set shorter than the unit period within the unit period. The amount is summed up a plurality of times, and as the predetermined condition, the difference between the maximum value and the minimum value of the summation result of the second unit period is a certain value or more, or the second It is characterized in that the difference between the maximum value and the minimum value of the total result of the unit period is a predetermined ratio or more with respect to the past target value or the past total result.

  That is, in the usage amount display device for energy and the like of this embodiment, in addition to counting the usage amount of energy such as gas, water, and electricity in a unit period, the second shorter than the unit period (for example, one day). The amount of energy used in the unit period (for example, 1 hour) is counted several times during the unit period. For example, the usage amount of energy and the like is totaled 24 times per hour (second unit period) for one day (unit period).

  Then, the maximum value and the minimum value of the plurality of aggregation results for the second unit period are compared, and the difference is less than a certain value, or the difference is a past target value or a past aggregation result. On the other hand, if it is less than the predetermined ratio (that is, the change in the actual usage amount is too small with respect to the target usage amount), the amount for one day including the second unit period (unit period) The target value is calculated by excluding the counting results from the integration target.

  Therefore, even in this embodiment, when there is a day when gas, water, or the like is not used (or extremely few even if used), the above-mentioned predetermined condition is not satisfied during the absence, even in this embodiment. Since it is excluded from the target of calculation of target value, the target value displayed on the display unit is based on the actual life (life excluding the absence period), and is an appropriate numerical target as the target value. Is set and displayed.

  In addition, in this embodiment, since it is determined whether or not to include the aggregation result of the unit period as an accumulation target of the target value calculation based on the aggregation result obtained by further subdividing the unit period, for example, it is absent from the afternoon. Even in such a case, if it is used in the morning as it is, the total result of the day will be included in the accumulation target, and a target value more suitable for real life can be set and displayed.

  According to the present invention, a usage amount display device for energy and the like that calculates and displays a target value of the usage amount of energy and the like used at home such as gas, water, and electricity based on past usage results of such energy and the like. In this case, when there is a period absent due to travel or the like, the target value is set by excluding the period, so that it is possible to set and display an appropriate target value according to the actual life.

Here, the hot water supply standby state means a state in which the controller 19 can start the combustion control of the burner 6 on condition that the water flow rate sensor 10 detects water flow of a certain flow rate or higher. The hot water supply stop state means that combustion control is not performed even when there is water flow exceeding the predetermined flow rate, that is, a state where the burner 6 is stopped without burning.

  The totaling unit 26 uses the energy such as gas, water, and electricity acquired by communication via the two-core communication circuit 24 for each type of energy and the like for each predetermined unit period T1. It consists of functional parts that aggregate. In the present embodiment, the totaling unit 26 totals the amount of gas and water used in the hot water supply device 1 obtained from the hot water supply device 1 and totals the amount of electricity used obtained from the measurement unit 3 described later. It is configured.

  As for the electricity usage, it may be configured to acquire the power usage measured by the measurement unit 3, but in the present embodiment, as will be described later, only the current value is measured by the measurement unit 3. The current value is acquired by the totaling unit 26, and the power consumption is calculated and totaled (details of the totalization will be described later).

  In connection with the totaling unit 26, the microcomputer 23 is provided with a non-volatile memory 28, and the totaling result totaled by the totaling unit 26 is stored in the memory 28 as appropriate for each type of energy or the like. It has become. The microcomputer 23 also has a clock function in relation to the unit period T1.

  The calculation unit 27 accumulates the usage amount of energy and the like in the unit period T1 totaled by the totaling unit 26, specifically, the totaling result of the totaling unit 26 stored in the non-volatile memory 28 for a certain number of times.

The current measuring unit 31 measures a current value supplied to the distribution board 30 via a current transformer (not shown) provided in the distribution board 30, and the measurement result is a two-core communication circuit 32. Is transmitted to the microcomputer 23 of the remote controller 2 (specifically, the counting unit 26).

  The measuring unit 3 is configured to be connectable to the water meter 4 and the gas meter 15 described above (see the one-dot chain line in FIG. 1), and obtains the water usage amount and the gas usage amount from these meters 4 and 15. If it is configured to transmit to the remote controller 2, the display unit 22 of the remote controller 2 can display the amount of water used and the amount of gas used in the entire home, and can also display these target values.

  Next, in the hot water supply system configured as described above, the display of the usage amount of gas and water in the hot water supply device 1 in the remote controller 2, the usage amount of electricity at home, and the display of the target value of each usage amount. explain.

First, the display of the amount of gas and water used in the hot water supply apparatus 1 and the amount of electricity used at home will be described. Among these, the usage amount of gas and water in the hot water supply apparatus 1 is acquired from the controller 19 of the hot water supply apparatus 1 by the microcomputer 23 (aggregation unit 26) communicating with the controller 19 of the hot water supply apparatus 1. And the usage-amount of the gas and water in the acquired hot water supply apparatus 1 is each converted into the display unit to the display part 22 in the microcomputer 23 (For example, if it is a gas usage-amount, the gas amount per hour [m < ³ > / hour]) In the case of water usage, the amount of water per minute [L / min]) is displayed, and the result is displayed on the display unit 22 of the remote controller 2. On the other hand, for the amount of electricity used at home, the microcomputer 23 (aggregation unit 26) communicates with the measurement unit 3 and acquires the current value measured by the current measurement unit 31 of the measurement unit 3. Then, the microcomputer 23 calculates the power usage from the acquired current value, converts the calculation result into a display unit on the display unit 22 (for example, power usage [kWh]), and causes the display unit 22 to display it.

  In addition, the display of each usage amount of gas, water, and electricity on the display unit 22 can be configured to be always displayed in a predetermined area of the display unit 22, and displayed according to a predetermined operation of the operation unit 21. It can also be configured to be displayed on the screen of the unit 22.

Next, display of target values for the amounts of use of gas, water, and electricity will be described.
In displaying these target values, the microcomputer 23 calculates target values for the respective usage amounts of gas, water, and electricity in the following procedure.

  That is, in calculating these target values, first, the microcomputer 23 (aggregation unit 26) sets a predetermined unit period T1 (for example, “one day”) set in advance for each of gas, water, and electricity. The usage amount is totaled every time the unit period T1 is “1 day”, and the totaled result is stored in the nonvolatile memory 28 every day.

  The microcomputer 23 (calculation unit 27) then counts a specific number of counts set in advance from the total results of past usage stored in the memory 28 for each of gas, water, and electricity. In this case, the totaled results accumulated a certain number of times from the latest totaled results are integrated. For example, when the above-mentioned predetermined number is “14”, the total results for 14 days (14 times) from the most recently stored total results for yesterday to the total results for 14 days ago are integrated, and gas, water, Find each integrated value of electricity.

  When the integrated values of gas, water, and electricity are obtained in this way, the microcomputer 23 (calculation unit 26) then divides each integrated value by the above-mentioned fixed number of times, respectively for gas, water, and electricity. The average value per day is calculated, and these average values are displayed on the display unit 22 as target values for the daily usage of gas, water, and electricity.

  By the way, in calculating each target value of gas, water, and electricity in this way, in the hot water supply system of the present embodiment, when the microcomputer 23 (aggregation unit 26) stores the aggregation results for each day in the memory 28. , Gas, water, and electricity total results are determined whether or not the predetermined condition A set in advance is satisfied, and if the predetermined condition A is not satisfied, the total result (predetermined condition A is not satisfied) The summation result is not stored in the memory 28. That is, the counting results that do not satisfy the predetermined condition A are not included in the integration target in the target value calculation in the microcomputer 23 (calculation unit 27).

  Here, the predetermined condition A is a condition set in order to select a total result that is not suitable for inclusion in the target value calculation target among the total results of the unit period T1, and as the predetermined condition A, For example, the total result of the unit period T1 is equal to or greater than a predetermined threshold value set in advance, or the total value of the unit period T1 is a target value set in the past (for example, a target value one day before) or a past unit period. It is used that the ratio is greater than or equal to a predetermined ratio with respect to the aggregation result at T1 (for example, the aggregation result one day ago).

  In other words, if the user is at home, the threshold is set based on the minimum expected usage (experience value), so that the user can be considered absent if the tabulation result is less than this threshold. Even if the result is extremely low relative to the past target value (or past aggregated result), the user can be regarded as absent in the same way, and the aggregated result when the user can be regarded as absent is targeted for accumulation. The predetermined condition A is set so that it can be excluded because it is not appropriate to include it.

  In the present embodiment, the totaling result that does not satisfy the predetermined condition A is not stored in the memory 28. For example, when the gas totaling result does not satisfy the predetermined condition A, the totaling of water and electricity is performed. Only the result is stored in the memory 28, and the storage area of the gas total result is vacated in one place, but this empty area leaves the data stored in the past without rewriting the data, and the gas When the total result of the next unit period T1 (that is, the next day) satisfies the predetermined condition A, the total result is stored in the empty area. In other words, in the present embodiment, it is sufficient that the memory 28 stores the total results of gas, water, and electricity as long as it can store the total results for the gas, water, and electricity. In calculating the value, when the microcomputer 23 (calculating unit 27) integrates the totaled results for a certain number of times, it is only necessary to simply add the data stored as the totaled results of gas, water, and electricity. .

  As described above, in the hot water supply system of the present embodiment, when setting the target values for gas, water, and electricity, the predetermined condition A is set when the counting result totaled by the counting unit 26 does not satisfy the predetermined condition A. Since the results that are not satisfied are excluded from the target of calculation of the target value calculation, the result of the absence of travel, gas, water, etc. is not used (or extremely low even if used). The target value corresponding to the actual life is displayed on the display unit 22 of the remote controller 2 without being based.

  In the present embodiment described above, whether or not the predetermined condition A is set individually for all of gas, water, and electricity that are targets for calculation of the target value, and the total result is stored in the memory 28. However, if at least one of gas, water, and electricity does not satisfy the predetermined condition A (for example, gas) If the total result of this does not satisfy the predetermined condition A), not only the total result of the energy etc., but also all other energy etc. (in this case, water and electricity) totaled during the same predetermined period T1 The total result can be configured not to be stored in the memory 28. Thereby, the period used as the basis of target value calculation can be made the same about all the energy, etc., and the target value according to actual life can be calculated.

  Further, for example, the predetermined condition A is set only for a part of gas, water, and electricity (for example, gas), and the total result of energy (that is, gas) for which the predetermined condition A is set is predetermined. If the condition A is not satisfied, not only the total result of the energy etc. but also the total result of all other energy etc. (in this case, water and electricity) totaled during the same predetermined period T1 is stored in the memory 28. It can also be configured not to let it. In this case, as the energy or the like for setting the predetermined condition A, energy or the like (for example, gas and water) that is likely to cause a large difference in the total result depending on whether the user is at home or not is suitably used.

Embodiment 2
Next, a second embodiment of the present invention will be described.
The hot water supply system shown in the second embodiment is obtained by modifying a method for calculating a target value of a usage amount of energy or the like in the remote controller 2 of the hot water supply system of the first embodiment described above. Common to the hot water supply system shown in the embodiment. Therefore, parts having the same configuration are denoted by the same reference numerals and description thereof is omitted.

  In the hot water supply system shown in the present embodiment, the microcomputer 23 (counting unit 26) of the remote controller 2 adds up each usage amount in a predetermined unit period T1 for each of gas, water, and electricity as described above. In the unit period T1, the usage amount such as energy in the second unit period T2 set shorter than the unit period T1 is totaled a plurality of times.

  Specifically, when the unit period T1 is one day, the second unit period T2 is set to a period (for example, 1 hour) shorter than the unit period T1. The microcomputer 23 (aggregation unit 26), in parallel with the aggregation of each usage amount of gas, water, and electricity during the unit period T1, gas and water in a short period divided by the second unit period T2. Calculating each usage of electricity multiple times. For example, one day (unit period T1) is divided by one hour (second unit period T2), and usage amounts of gas, water, and electricity are totaled every hour. That is, in this case, the usage amount of energy and the like in the second unit period T2 is totaled 24 times. Then, the totaling results in the second unit period T2 tabulated in this way are stored in a memory (not shown).

  Then, the microcomputer 23 (aggregation unit 26) stores the total results of gas, water, and electricity usage in the unit period T1, that is, the total results for one day of gas, water, and electricity, in the memory 28. By comparing the maximum value and the minimum value of the total result stored in the memory (not shown) as the total result of the second unit period T2, it is determined whether or not the difference satisfies the predetermined condition B, and the unit period It is determined whether or not the total result at T1 is stored in the memory 28.

  In this way, by using the second unit period T2 shorter than the unit period T1, and by looking at the difference between the maximum value and the minimum value of the total result of energy and the like in the second unit period T2, the unit period T1 It can be determined whether or not the usage amount of gas, water and electricity has changed. That is, if there are no users throughout the day, the usage of gas, water and electricity hardly changes throughout the day, but if the user stays at home for a certain amount of time during the day, gas will be consumed during that time. Since there is a change in the amount of water and electricity used, the presence or absence of such a change is judged from a plurality of tabulated results in the second unit period T2.

  Therefore, as the predetermined condition B, for example, the difference between the maximum value and the minimum value of the aggregation result of the second unit period T2 is a certain value or more, or the aggregation result of the second unit period T2 For example, the difference between the maximum value and the minimum value is a predetermined ratio or more with respect to the past target value or the past count result.

  Thus, in the hot water supply system of this embodiment, when setting the target values for gas, water, and electricity, the microcomputer 23 (counting unit 26) counts the amount of gas, water, and electricity used in the unit period T1. In addition, within the unit period T1, the usage amounts of gas, water, and electricity in the second unit period T2 set shorter than the unit period T1 are counted a plurality of times, and the total results of these second unit periods T2 When the difference between the maximum value and the minimum value does not satisfy the predetermined condition B, the total result of gas, water, and electricity in the unit time T1 including the second unit period T2 is excluded from the target of the target value calculation. Therefore, the total result of the day that is absent due to travel, etc. and gas or water is not used (or extremely low even if used) is not used as a basis for target value calculation, and the display unit 22 of the remote controller 2 Target value in line with the life of the time is displayed.

  In addition, in this embodiment, it is determined whether or not to include the aggregation result in the unit period T1 as an accumulation target of the target value calculation based on the aggregation result of the second unit period T2 obtained by further subdividing the unit period T1. Therefore, for example, even if the absence from the afternoon, for example, if only the gas is used in the morning to satisfy the predetermined condition B, the total result of that day (unit period T1) is the target for the gas. While being included in the target of value calculation, the total results of water and electricity that did not satisfy the predetermined condition B will be excluded from the target of target value calculation, and a target value that is more realistic is set. Will be.

  In the second embodiment as well, the predetermined condition B is individually set for all of gas, water, and electricity that are targets for calculation of the target value, and the total result of the unit period T1 is stored in the memory 28. In the case of determining whether gas, water, and electricity are individually determined, for example, if at least one of gas, water, and electricity does not satisfy the predetermined condition B, The first embodiment can be configured so that not only the total results of energy and the like, but also the total results of all other energy totaled during the same predetermined period T1 are not stored in the memory 28. It is the same.

  In addition, if the predetermined condition B is set only for a part of gas, water, and electricity and the predetermined condition B is not satisfied for the energy or the like for which the predetermined condition B is set, the total result of the energy and the like is of course This is also the same as in the first embodiment in that the memory 28 can also be configured not to store the total results of all other energies and the like totaled during the same predetermined period T1.

  The above-described embodiments show preferred embodiments of the present invention, and the present invention is not limited to these, and various design changes can be made within the scope of the invention.

  For example, in the above-described embodiment, the case where the present invention is applied to the remote controller 2 of the hot water supply system is shown. However, the present invention is not limited to the remote controller 2 of the hot water supply apparatus 1 and is displayed on the display unit of the remote controller of the heat source device other than the hot water supply apparatus. Needless to say, the present invention can be applied to display units such as house equipment and household appliances other than the heat source machine. In addition, when the hot water supply apparatus 1 uses petroleum as a fuel (in the case of an oil heat source machine), it is needless to say that the amount of oil used is displayed as a target value instead of gas.

  In the above-described embodiment, the remote controller 2 is configured to set and display target values for the usage amounts of gas, water, and electricity, but only at least one of these (for example, gas) is shown. It can also be configured to set and display the target value. In addition, it takes in the amount of water and gas used from the water meter 4 and gas meter 15, and sets and displays the target value for the amount of water and gas used in the entire home. It can also be configured to.

  Further, in the above-described embodiment, a case has been described in which the aggregation results that do not satisfy the predetermined condition A (or the predetermined condition B) are excluded from the target of the target value calculation by not being stored in the memory 28. In addition, a result of aggregation that does not satisfy the predetermined condition A (or the predetermined condition B) is also stored in the memory 28, and the total that does not satisfy the predetermined condition A (or the predetermined condition B) when integrating by the computing unit 27 You may comprise so that a result may be excluded from the integrating | accumulating object of target value calculation. The calculation of the target value performed by excluding the aggregation result that does not satisfy the predetermined condition A (or the predetermined condition B) from the integration target is, of course, stored when the aggregation result excluded from the integration target is not stored in the memory 28. However, it is also possible to calculate the average value by subtracting the number of times corresponding to the period excluded from the above-mentioned fixed number of times of summing up the totaled results when calculating the average value. That is, as in the above-described embodiment, it is possible not to obtain an average value including old data but to obtain an average value only from the latest tabulation result.

In the above-described embodiment, the amount of energy used and its target value are displayed. For example, the amount of CO ² emitted from the amount of used gas, oil, electricity, etc., and the reduction target thereof are displayed. It is also possible to configure as described above. That is, the present invention can be applied not only to the display of the amount of energy used and its target value, but also to the display of other items converted from the energy.

  Further, in the above-described embodiment, the case where the totaling unit 26 and the calculation unit 27 are built in the remote controller 2 has been described. However, if the remote controller 2 constituting the usage amount display device for energy or the like is provided, In particular, the remote controller 2 may not be incorporated, and for example, the remote controller 2 may be distributed in the hot water supply device 1 or the measurement unit 3.

  Further, in the above-described embodiment, the case where the usage amount display device for energy and the like according to the present invention is applied to a hot water supply system for home use used in a general home such as an apartment house or a detached house is shown. Of course, the present invention can be applied not only to such a hot water supply system for home use, but also to a hot water supply system for business use used in a facility (so-called commercial facility) such as a shower room in a sports gym or a hotel bathroom.
