[0026] The energy usage amount display unit according to the first embodiment is applied to a remote control unit 1 in communicative connection with a water heater 2 for remotely operating the water heater. The energy usage display unit displays on the remote control unit 1 the consumption of gas and water used by the water heater 2 and the electricity consumption of the entire house where the water heater is installed (see figure 1 ).

[0027] Such as figure 1 As shown, the water heater 2 includes a heat exchanger 21, a burner 22 for heating the heat exchanger 21, a water supply pipe 23 and a hot water outlet pipe 24 connected to the heat exchanger 21 through pipes, which are used to feed the burner 22 A gas supply pipe 25 for supplying gas, a control unit 26 for controlling the operation of the water heater 2 , and a power circuit 27 . The remote control unit 1 and the control unit 26 are in a communicative connection.

[0028] The gas supply pipe 25 is equipped with a ...

[0068] In the second embodiment, as Figure 5 As shown, the calculation processing part 11a does not include the day memory 62, the month memory 63, the day calculation part 52, and the month calculation part 53 of the first embodiment, while the calculation part 5a is arranged in the time calculation part 51, and the storage part 6a is configured in time memory 61. In this case, as figure 1 In that way, the display control section 14 reads out the usage data in the time memory 61 and the time calculation section 51 by the period required by the user using the display item selection section 13, calculates and prepares for displaying the usage data on the display section 15. data, and output it on the display section 15. Therefore, in order to compare the current usage amount and the past usage amount during the comparison period, the past usage amount data during the comparison period is stored in the time memory 61 . With this structure, similar to the first embodiment, i...

Abstract

An energy usage display unit for displaying energy usage of gas used for a water heater, water used for the water heater or electricity used in housing where the water heater is set, comprising: a clock section for having a clock and calendar function; a counting section for counting usage of gas, water or electricity; a memory section for storing a count value of usage counted by the counting section retroactive to past by a predetermined number with a predetermined time unit; a counting control section for writing the count value of usage from the counting section to the memory section at predetermined time; a display control section for reading one or both of the count value of the counting section and a stored value in the memory section to prepare display data of usage, in accordancewith a period unit required by a user; and a display section for displaying usage based on the display data prepared by the display control section.

Description

technical field [0001] The present invention relates to an energy usage display unit for displaying energy usage, such as gas usage or electricity usage for water supply service for a water heater or a residence in which the water heater is installed. Background technique [0002] In general, a water heater capable of displaying the amount of water or gas used by the water heater is known (Japanese Patent No. 3061215). Such as Figure 6 As shown in the block diagram of , as a configuration for displaying the usage of gas and the like, the water heater includes a gas volume detection device 631, a water volume detection device 641, a gas volume accumulation device 674, a water volume accumulation device 675, a cycle accumulation and Management means 673, storage means 677, display means 676, display switching means 678, accumulation period setting means 671, clock means 672 and the like. [0003] The gas amount accumulating means 674 adds up the gas amount used in the water ...
