The display state of the display 3d in FIG. 4 is a display in a state where the extra function is operating only at midnight.

FIG. 5 is a flowchart showing a flow of control processing of the hot water heater according to the first embodiment, and details of the control operation will be described using this flowchart and FIGS.
In step S1, a communication signal for identifying whether the hot water heater main body control unit 1d of the bath water heater main body 1 is a model having an upper side extra function as a daytime extra function or a model having an extra function at night is used as a communication circuit. Whether the main remote control 3 has the upper side extension function as the daytime side hot water supply body 1 by adding the signal from the communication circuit 3c of the main remote control 3 to the main remote control unit 3a. It is determined whether or not the model has an additional function only at midnight.
If the communication signal received from the bath water heater main body 1 is determined to be a model having an upper side expansion function, the communication signal received from the bath water heater main body 1 is a model having a side expansion function only at midnight. If it is determined, the process branches to step S3.

In step S2, the main remote controller 3 determines that the hot water heater main body 1 is connected to a model having an upper side extension function. For example, a flag (upper side extension model) is set in a memory built in the main remote controller 3a.
In step S3, the main remote controller 3 determines that the bath water heater main body 1 is connected to a model having an extra function only at midnight. For example, a flag (increase only at midnight) is set in a memory built in the main remote controller 3a.

  In step S4, it is determined whether the model has an upper side extension function as a daytime side extension function determined in steps S2 and S3 or a model having a side extension function only at midnight. In the case of a model having an upper side extension function, the process branches to step S5, and in the case of a model having a side extension function only at midnight, the process branches to step S6.

In step S5, it is determined whether or not the upper side extension switch 3e has been pressed for a predetermined time or more. If the button has been pressed for a predetermined time or longer, the process branches to step S7. If the button has not been pressed for the predetermined time or longer, the process returns to step S5 and waits until the upper side additional switch 3e is pressed for a predetermined time or longer.
In step S6, it is determined whether or not the extra switch 3e is pressed for a predetermined time or more only at midnight. If the button has been pressed for a predetermined time or longer, the process branches to step S8. If the button has not been pressed for the predetermined time or longer, the process returns to step S6, and waits until the switch 3e is pressed for a predetermined time or more only at midnight.

In step S7, since the bath water heater main body 1 is a model having an upper side extension function, a communication signal for starting the upper side extension function is output from the main remote controller 3a to the communication circuit 3c. The hot water heater main body control unit 1d receives the signal via the communication circuit 1c to start the operation of the upper side expansion function.
In addition, the main remote controller 3a outputs an indication of the start of the upper side extra function to the display 3d (see FIG. 3).
In addition, the main remote control unit 3a outputs a voice phrase utterance command to start the operation of the upper side extension function to the voice conversion unit 3f, and for example, “set” is output from the speaker 3h via the amplifier 3g. Speak and let the operator recognize by voice that the upper side extension function has begun to work. Thereafter, the process proceeds to step S9.

In step S8, since the bath water heater main body 1 is a model having a function to increase the nighttime only, the main remote control unit 3a outputs a communication signal for starting the function to increase the nighttime service to the communication circuit 3c. The hot water heater main body control unit 1d of the main body 1 receives the signal via the communication circuit 1c to start the operation of the extra function only at midnight.
In addition, the main remote control control unit 3a outputs a display indicating that the extra function is started only at midnight (see FIG. 4).
In addition, the main remote control unit 3a outputs a voice phrase utterance command to start the operation of the extra function only at midnight to the voice conversion unit 3f. For example, “set” is output from the speaker 3h via the amplifier 3g. And the operator recognizes by voice that the upper side extension function has started to operate. Thereafter, the process proceeds to step S9.

  In step S9, it is discriminated again whether it is a model having an upper side extension function as a daytime side extension function determined in steps S2 and S3 or a model having a side extension function only at midnight. In the case of a model having an upper side extension function, the process branches to step S10, and in the case of a model having a side extension function only at midnight, the process branches to step S11.

In step S10, it is determined whether the upper side extension switch 3e has been pressed for a predetermined time or more. If it has been pressed for a predetermined time or longer, the process proceeds to step S12. If it has not been pressed for a predetermined time or longer, the process returns to step S10 and waits until the upper side additional switch 3e is pressed for a predetermined time or longer.
In step S11, it is determined whether or not the extra switch 3e has been pressed for a predetermined time or more only at midnight. If it has been pressed for a predetermined time or longer, the process proceeds to step S13. If it has not been pressed for a predetermined time or longer, the process returns to step S11 and waits until the switch 3e is pressed for a predetermined time or longer only at midnight.

In step S12, since the hot water heater main body 1 is a model having an upper side additional function, a communication signal for stopping the upper side additional function is output from the main remote controller 3a to the communication circuit 3c. The hot water heater main body control unit 1d receives the signal via the communication circuit 1c to stop the operation of the upper side expansion function.
In addition, the main remote control control unit 3a outputs a display indicating that the upper side extra function is stopped to the display 3d (see FIG. 2A).
In addition, the main remote control unit 3a outputs a voice phrase utterance command to stop the operation of the upper side extension function to the voice conversion unit 3f, and utters, for example, “released” from the speaker 3h via the amplifier 3g. Then, the operator recognizes by voice that the upper side extension function has stopped.

In step S13, since the bath water heater main body 1 is a model having a function for increasing the nighttime only, the main remote control unit 3a outputs a communication signal for stopping the operation for the nighttime increasing function to the communication circuit 3c. The hot water heater main body control unit 1d of the main body 1 receives the signal via the communication circuit 1c and stops the operation of the extra function only at midnight.
Further, the main remote controller 3a outputs a display indicating that the extra function is stopped only at midnight on the display 3d (see FIG. 2B).
In addition, the main remote control unit 3a outputs a voice phrase utterance command to stop the operation of the extra function only at midnight to the voice conversion circuit 3f, and for example, “released” is output from the speaker 3h via the amplifier 3g. Speak out and let the operator recognize by voice that the extra function stopped at midnight.

As described above, in the first embodiment, the function of the connected model is automatically performed regardless of which model is connected to the different bath water heater main body 1 that does not have a daytime extra function. Therefore, for example, a switching operation by a change-over switch is not necessary, and it is easy to use.
In addition, since the notification content by voice, electronic sound, etc. and the display content for visual recognition are selected corresponding to the connected model, the operability of the dedicated remote controller corresponding to the conventional model is selected. Never lose the goodness of.
Further, since the control operation corresponding to the model is automatically performed only by the operator operating the extra switch 3e in the daytime, it is convenient for the operator.

In the first embodiment, the side switch 3e disposed on the main remote controller 3 has been described as an example. However, the same applies to the side switch 2e disposed on the bathroom remote controller 2. In this case, the same effect can be obtained. It is done.
Further, it is needless to say that the present invention is not limited to the control method of the flowchart of FIG. 5 and may be changed as appropriate.
For example, a control program corresponding to the model may be prepared, and once the model is determined, the corresponding control program may be executed.
Moreover, although the case where the bathroom remote control 2 and the main remote control 3 are connected to the bath water heater main body 1 via a wire has been described, signals may be exchanged wirelessly.
Embodiment 2. FIG.

Next, a second embodiment of the present invention will be described.

FIG. 6 shows a second embodiment of the present invention, in which the main remote controller 3 is connected to a model that does not have an upper side extension function that is a daytime side extension function, and the upper side extension switch 3e is pressed for a predetermined time or more. It is a screen display figure of the indicator 3d at the time.
A pop-up window 3i in which contents that cannot be used for the upper side extension function are written in text is displayed to prompt the operator to call attention. Needless to say, the display will be the same when connected to a model that does not have an extra function at night.

FIG. 7 shows another example of the second embodiment of the present invention. The screen of the display 3d when the main remote controller 3 is connected to a model that does not have the upper side extension function that is the daytime side extension function. It is a display figure.
When a model that does not have a daytime extra function is connected, all of the displayed daytime extra switches 3e are not displayed.

Next, details of the control of the second embodiment of the present invention will be described with a focus on the flowchart of FIG.
In step S21, the hot water heater main body control unit 1d of the bath water heater main body 1 outputs a communication signal for identifying whether the model has a daytime extra function or not to the communication circuit 1c. 3 is received by the main remote control unit 3a of the main remote controller 3, so that the main remote controller 3 is a model in which the hot water heater body 1 has a daytime extra function or not. Determine if it exists. If the communication signal received from the bath water heater main body 1 is a model having a daytime extra function, the communication signal received from the bath water heater main body 1 is a model having no daytime extra function. In that case, the process branches to step S23.

In step S22, it is determined that the main remote controller 3 is connected to the model of the bath water heater main body 1 having a daytime extra function. For example, a flag (an additional model for daytime) is set in a memory built in the main remote controller 3a.
In step S23, the main remote controller 3 determines that the hot water heater main body 1 is connected to a model having a daytime extra function. For example, a flag (other than a daytime extra model) is set in a memory built in the main remote controller 3a.

  In step S24, it is determined whether or not the daytime extra switch 3e is pressed for a predetermined time or more. If it has been pressed for a predetermined time or longer, the process proceeds to step S25. If it has not been pressed for a predetermined time or longer, the process returns to step S24 and waits until the daytime extra switch 3e is pressed for a predetermined time or longer.

  In step S25, it is determined again whether or not the model has the daytime extra function determined in steps S22 and S23. If the model has a daytime extra function, the process branches to step S26. If the model does not have a daytime extra function, the process branches to step S27.

In step S26, since the bath water heater main body 1 is a model having a daytime extra function, the main remote controller 3a outputs a communication signal for starting the day extra function to the communication circuit 3c, and the hot water heater The main body control unit 1d of the main body 1 receives the signal via the communication circuit 1c to start the operation of the extra daytime function.
The main remote controller 3a outputs a display indicating the start of the daytime extra function to the display 3d (see FIGS. 3 and 4).
In addition, the main remote control control unit 3a outputs a voice phrase utterance command to start the operation of the daytime extra function to the voice conversion unit 3f, and is set, for example, from the speaker 3h via the amplifier 3g. ”And let the operator recognize by voice that the extra daytime function has started to work. Thereafter, the process proceeds to step S28.

In step S7, since the bath water heater main body 1 is a model that does not have the daytime extra function, the main remote control control unit 3a does not output a communication signal for starting the daytime extra function to the communication circuit 3c.
In addition, the main remote controller 3a outputs a display for prohibiting the operation of the extra daytime function to the display 3d (see FIG. 6).
The main remote control unit 3a outputs a voice phrase utterance command prohibiting the operation of the extra daytime function to the voice conversion unit 3f, and utters, for example, "cannot be set" from the speaker 3h via the amplifier 3g. , Let the operator recognize that the function is prohibited by voice. Thereafter, the process proceeds to step S28.

  In step S28, it is determined whether or not the daytime extra switch 3e is pressed for a predetermined time or more. If it has been pressed for a predetermined time or longer, the process proceeds to step S29. If it has not been pressed for a predetermined time or longer, the process returns to step S28 and waits until the daytime extra switch 3e is pressed for a predetermined time or longer.

  In step S29, it is determined again whether the model has the daytime extra function determined in steps S22 and S23. If the model has a daytime extra function, the process branches to step S30. If the model does not have a daytime extra function, the process branches to step S31.

In step S30, since the bath water heater main body 1 is a model having a daytime extra function, the main remote controller 3a outputs a communication signal for stopping the daytime extra function to the communication circuit 3c. The main body control unit 1d of the main body 1 stops the operation of the daytime extra function by receiving the communication via the communication circuit 1c.
Further, the main remote control unit 3a outputs a display indicating that the daytime extra function is stopped to the display 3d (see FIG. 2A).
Also, a voice phrase utterance command for stopping the operation of the daytime extra function is output from the main remote controller 3a to the voice conversion unit 3f, and for example, “canceled” from the speaker 3h via the amplifier 3g. And let the operator recognize by voice that the extra function during the daytime has stopped.

  In step S31, the same control as in step S27 is performed.

As described above, also in the second embodiment, the function of the connected model is the same regardless of which model is connected to the different hot water heater main body 1 that has or does not have a daytime extra function. Since the automatic recognition is performed, for example, a switching operation by a changeover switch or the like is not necessary, and the usability is good.
In addition, since the notification content by voice, electronic sound, etc. and the display content for visual recognition are selected corresponding to the connected model, the operability of the dedicated remote controller corresponding to the conventional model is selected. Never lose the goodness of.
Further, since the control operation corresponding to the model is automatically performed only by operating the additional switch 3e by the operator, it is convenient for the operator.

In step S41, the hot water heater main body control unit 1d of the bath water heater main body 1 outputs a communication signal for identifying whether the model has an automatic bath water heater function or not to the communication circuit 1c. By receiving a signal from the communication circuit 3c by the main remote controller 3a, it is determined whether the main remote controller 3 is a model in which the bath water heater main body 1 has or does not have an automatic bath hot water supply function. If the communication signal received from the bath water heater body 1 is a model having an automatic bath water heater function, the process proceeds to step S42. If the communication signal received from the bath water heater body 1 is a model not having an automatic bath water heater function, step S43 is performed. Branch to

In step S42, the main remote controller 3 determines that the bath water heater main body 1 is connected to a model having an automatic bath hot water supply function.
For example, a flag (automatic hot water supply model) is set in a memory built in the main remote controller 3a. In step S43, the main remote controller 3 determines that the bath water heater main body 1 is connected to a model that does not have an automatic bath hot water supply function.
For example, a flag (other than the automatic bath water heater model) is set in a memory built in the main remote controller 3a.

  In step S44, it is determined whether or not the automatic bath switch 3j has been pressed. If the bath automatic switch 3j is pressed, the process proceeds to step S45. If the bath automatic switch 3j is not pressed, the process returns to step S44 and waits until the bath automatic switch 3j is pressed.

  In step S45, it is determined whether the machine has the automatic hot water supply function determined in steps S42 and S43 or not. If the model has an automatic bath hot water supply function, the process branches to step S46. If the model does not have an automatic bath hot water supply function, the process branches to step S47.

In step S46, since the bath water heater body 1 has an automatic bath water heater function, a communication signal for starting the operation of the automatic bath water heater function is output from the main remote controller 3a to the communication circuit 3c. The hot water heater main body control unit 1d receives the signal via the communication circuit 1c to start the operation of the automatic bath hot water supply function.
In addition, the main remote control control unit 3a outputs an operation start display of the automatic hot water supply function to the display 3d (see FIG. 10).

Thereafter, the process proceeds to step S48.

In step S47, since the bath water heater main body 1 is a model that does not have an automatic bath hot water supply function, a communication signal for starting the operation of the automatic bath hot water supply function is not output from the main remote controller 3a to the communication circuit 3c. In addition, an operation prohibition display of the automatic hot water supply function is output from the main remote controller 3a to the display 3d (see FIG. 11).
Also, a voice phrase utterance command prohibiting the operation of the automatic bath water heater function is output from the main remote controller 3a to the voice converter 3f, and for example, "cannot be set" is uttered from the speaker 3h via the amplifier 3g. , Let the operator recognize that the function is prohibited by voice. Thereafter, the process proceeds to step S48.

  In step S48, it is determined whether or not the automatic bath switch 3j has been pressed again. If the automatic bath switch 3j is pressed again, the process proceeds to step S49. If the automatic bath switch 3j is not pressed, the process returns to step S48 and waits until the automatic bath switch 3j is pressed.

  In step S49, it is determined again whether the machine has the automatic hot water supply function determined in steps S42 and S43. If the model has an automatic bath hot water supply function, the process branches to step S50. If the model does not have an automatic bath hot water supply function, the process branches to step S51.

In step S50, since the bath water heater body 1 is a model having an automatic bath water heater function, a communication signal for stopping the automatic bath water heater function is output from the main remote controller 3a to the communication circuit 3c. The hot water heater main body control unit 1d receives the signal via the communication circuit 1c to stop the operation of the automatic bath hot water supply function.
Further, the main remote controller 3a outputs a display indicating that the automatic hot water supply function is stopped to the display 3d (see FIG. 9).
