  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the drawings.

  FIG. 1 shows a remote controller 1 for a water heater that functions as a resource usage display device according to an embodiment of the present invention. The remote controller 1 remotely controls a water heater (not shown) as a heat source device, and is connected to the water heater so that information can be exchanged with each other by wire or wirelessly. In addition, a measurement unit (not shown) for measuring the consumption of resources such as gas, electricity and water consumed in the building is installed separately from the water heater, and the information measured by the measurement unit is It is configured to be transmitted to the remote controller 1 through a water heater or directly.

  The water heater can measure the instantaneous gas usage and the instantaneous water consumption used by the hot water heater with a built-in sensor, and can transmit the information to the remote controller 1. Further, the water heater may measure the hot water flow rate and the hot water temperature, calculate the gas usage amount and the water usage amount required for the hot water based on these, and transmit them to the remote controller 1.

  The measurement unit measures the instantaneous gas usage and instantaneous water usage based on the detection signals of the gas meter and water meter attached to the building, and detects the current sensor (current transformer) and voltage sensor attached to the commercial power system. The instantaneous power consumption can be measured based on the signal, and the information can be transmitted to the remote controller 1. Note that the function of the measurement unit can be incorporated in the water heater. In general, the amount of power used (yen) is expressed as “electricity charge”, and the amount of power is also expressed as “electricity” in this specification.

  The remote controller 1 is an operating device for mainly performing remote control of a water heater, and includes a control unit (not shown) mainly composed of a microprocessor, a memory (storage means), etc., and display control by the control unit. A display 2 to be performed and an operation unit 3 for performing various operations are provided. The control unit has a clock function using an internal clock. Further, the control unit includes various control programs and various control data in the memory, and executes various controls including resource usage display control described later using these control programs and control data.

  The display 2 displays an operation content of the operation unit 3 of the remote controller 1 and an operation state of the water heater. In the illustrated embodiment, a segment type display is shown. The display 2 may be directly controlled by the microprocessor of the control unit, or may be display-controlled by the microprocessor via the low-level control controller of the display 2.

  The operation unit 3 includes an “operation on / off” switch, a “calling” switch, a “tracking” switch, a “bath automatic” switch, an up / down switch 31 for setting switching operations such as a hot water supply temperature and selection items, ”Switch,“ volume ”switch,“ floor reservation ”switch,“ clock adjustment ”switch, energy changeover switch 32, and today / yesterday changeover switch 33. It should be noted that reference numerals are assigned only to switches related to the present invention, and reference numerals are omitted for switches that are less relevant. The control unit transmits a corresponding command signal to the water heater when necessary by a predetermined operation of each switch, and transmits a command signal to the display 2 so as to perform display according to each operation.

Based on the information transmitted from the water heater or the measurement unit, the control unit of the remote controller 1 has a daily gas usage amount, a water usage amount, an electric power usage amount, and a power usage amount. The CO ₂ emission amount is stored for a predetermined number of days, for example, the latest 15 days including today. Today's gas usage, water usage, and power usage can be obtained by integrating the instantaneous usage transmitted from the water heater or measurement unit by the control unit of the remote control 1, or the measurement unit or water heater side. Can be transmitted to the control unit of the remote controller 1 in real time or at predetermined time intervals (for example, every 10 minutes). Today's CO ₂ emissions can be approximated based on today's electricity usage and today's gas usage. Where and how to calculate the daily gas usage, water usage, power usage, and CO ₂ emissions stored by the control unit of the remote controller 1 is not the gist of the present invention and can be configured appropriately. .

In the memory of the control unit, a plurality of target resource amounts for each resource type such as daily target gas amount, target water amount, target power amount and target CO ₂ emission amount are stored. Each target resource amount can be set in advance as a reference value at the time of factory shipment of the remote controller 1, but in the present embodiment, the control unit learns based on the past usage situation and each target resource amount. Is calculated and stored. For example, the control unit calculates an average value per unit period (for example, one day) of the resource usage for each resource type for the past predetermined period (for example, for 14 days) such as gas, water, electricity, etc. The average value for each type can be updated as today's target resource amount. The update of the target resource amount today can be configured to be performed at 0: 1, for example. When updating the target resource amount of today, the target resource amount set immediately before that can be stored in the memory as the target resource amount of yesterday. Similarly, the target resource amount for the past 14 days can be stored for each day and for each resource type. As described above, by regularly updating the target resource amount based on the past use amount, it is possible to automatically update the target value appropriate for each resource type according to the actual use state of the user. It should be noted that today's target resource amount can be configured so that the user can manually set it. Further, the unit of the value of each resource amount stored in the memory may be appropriate, and can be displayed as a unit-converted value at the time of display.

When the hot water supply amount display is performed, the character display “yu” can be displayed on the dot matrix display portion 4 in the region B, and when the used gas amount display is performed, the character display “gas” is displayed on the dot matrix display portion 4. be able to.

  The control unit is configured to sequentially select one of power, gas, water, and CO2 each time the energy changeover switch 32 is pressed. Thus, the energy selection switch 32 constitutes a type selection operation unit. More specifically, for example, as shown in FIG. 2, when the switch 32 is pressed during display of the top screen, the power is selected. When the switch 32 is pressed during the power selection, the gas is selected. When the switch 32 is pressed, the water supply is selected. When the switch 32 is pressed during the water supply selection, CO2 is selected. When the switch 32 is pressed during the CO2 selection, the top screen is displayed. The order of selection of these resources may be appropriate, and is not limited to the order of the illustrated examples.

  Further, in the illustrated example, when the switch 32 is pressed during the top screen display, first, the current power consumption is displayed in the area C of the display 2 as a value converted into a charge. Other item values may be displayed, and yesterday item values may be displayed.

  A plurality of selection items related to each resource are roughly divided into selection items related to today and selection items related to yesterday. As multiple selection items for each resource for each day, the charge conversion value of the used resource amount, the charge conversion value of the target resource amount, the value of the used resource amount by the unit for each resource type, and the used resource amount for each resource type Four values based on units are provided. As for the CO2 emission amount, there are two CO2 emission amounts (actual integrated values) and a target amount for today and yesterday.

  A plurality of selection items related to today of the selected type are configured to be sequentially switched by the up / down switch 31 (use amount / target amount switching operation unit), and similarly, a plurality of selection items related to yesterday of the selected type. The up / down switch 31 can be used to sequentially switch between the selection items. However, the selection item related to today and the selection item related to yesterday are not switched depending on the operation of the up / down switch 31.

  Switching between the selection item related to today and the selection item related to yesterday is configured to be performed by the today / yesterday switching switch 33 (period selection operation unit), and the switch 33 is in a state where any selection item of today is selected. When is pressed, the selection item of yesterday corresponding to the item selected immediately before is selected, and when any of the selection items of yesterday is selected, pressing the switch 33 selects the item immediately before that. The selected item for today corresponding to the selected item is selected. That is, every time the today / yesterday changeover switch 33 is pressed, two corresponding selection items of the same type, the same unit, the usage amount or the target amount corresponding to the same today and yesterday are alternately selected.

  In addition, when the energy changeover switch 32 is pressed in a state where any type is selected, the same period (today or yesterday is the same), whether or not the charge conversion value is the same, whether the usage amount or the target amount is the same The selection items corresponding to the different types are selected (for example, if the switch 32 is pressed while the yesterday's power consumption (kWh) is selected, the yesterday's gas usage (m3) is selected. Preferably, the selection item that is in the initial selection state when the type is selected by the switch 32 for each resource type may be fixed.

  Thus, the up / down switch 31, the energy changeover switch 32, the today / yesterday changeover switch 33, and the control unit that executes the selection control make it possible to use a plurality of resources used for each of the plurality of types today, The selection control means is configured to select any one of a plurality of selection items including the target resource amount of yesterday, the plurality of used resource amounts for each of the plurality of types yesterday, and the target resource amount for each of the plurality of types of yesterday.

FIG. 3A is a screen that displays a value obtained by converting the amount of gas used today that is selected by pressing the energy changeover switch 32 twice from the top screen. During the screen display, the character matrix “gas” indicating the resource type is displayed on the dot matrix display section 4 in the area B of the display 2 and a plurality of segments 5 are used for today's target gas amount. It is configured to display a graph with an arc-shaped figure indicating the gas amount ratio. More specifically, when the ratio of the used gas amount to the target gas amount is 0 to 10%, only one segment 5a at the start position is displayed, and the arcuate graphic is adjacent every time the ratio increases by 10%. The segments 5 are additionally displayed sequentially. When the ratio is 90 to 100%, 10 continuous segments 5 from the start position are displayed. Furthermore, when the ratio is 100 to 110%, the eleventh segment 5 is displayed, when the ratio is 110 to 120%, the twelfth segment 5 is displayed, and when the ratio is 120 to 130%, the thirteenth segment, that is, the end is displayed. The position segment 5b is displayed.
