Description of the Related Art As shown in FIG. 4, a conventional hot water supply apparatus of this kind supplies hot water to a plurality of hot water sources via hot water pipes 4 from a water heater 3 having a heating means 1 and a heat exchanger 2 heated by the heating means 1. The tap 5 is configured to be supplied with hot water. The main body control device 6 controls the combustion state of the water heater 3, and also connects the main remote controller 7 and the 70 remote controller 8 individually with multi-core cables.

As shown in FIGS. 5 and 6, the main remote controller 7 and the flow remote controller 8 each have means for setting the hot water temperature, and the set value is input to the main body controller 6 through a dedicated line. A changeover switch 9 for changing over the right to set the hot water temperature is provided on the flow remote control 8 side, and the changeover switch 9 invalidates the setting on the main remote control 7 side and selects one of the setting values.

Problems to be Solved by the Invention However, with the above configuration, when the changeover switch is on the fluoro remote control side, the hot water temperature cannot be set on the main remote control side, so it is not possible to set the hot water temperature on the main remote control side. If you leave it on the 70 remote control side, you will not be able to set the water temperature with the main remote control unless you go to the 70 remote control and change the changeover switch.
The problem was that it was difficult to use. Furthermore, when the number of remote controllers increases to three or more, there is a problem in that it becomes very inconvenient to use a single switch to centrally switch the right to set the hot water temperature. Ta.

The present invention solves such conventional problems, and aims to enable setting of hot water temperature and switching of setting authority using a plurality of remote control devices without impairing usability.

Means for Solving the Problems In order to solve the above problems, the water heater of the present invention includes a water heater having a heating means, a heat exchanger heated by the heating means, and hot water heated by the water heater. a main control device that controls the combustion state of the water heater, a display means that indicates the operating state of the water heater and the setting of the hot water outlet temperature, a setting means that sets the hot water temperature setting authority, and a setting means that sets the hot water outlet temperature. , a plurality of remote control devices having a notification means for notifying the transfer of the right to set the outlet hot water temperature for a certain period of time by sound,
The hot water temperature is set by transmitting the set value to the main control device each time the hot water temperature is set. If the right to set the hot water temperature is requested from another remote control device, the right to set the hot water temperature is set. The remote control device has a system that uses notification means to give advance notice of the transfer of the setting right for a certain period of time, and prohibits the transfer by operating the setting means during the notice.

According to the above-described configuration, the present invention allows the remote control device to set the hot water temperature by transmitting the set value to the main body control device each time, and the main body control device sets the hot water temperature. You can connect any remote control device,
The hot water temperature can be set from any remote control device. or,
The right to set the hot water temperature is given by a warning sound that warns you of the movement for a certain period of time when you move to another remote control device, and you can prohibit movement by operating the setting means while the notification sound is sounding. This can prevent setting rights from being transferred to another remote control device.

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings.

In FIG. 1, a heating means 1 heats a heat exchanger 2, and the hot water heated by the heat exchanger 2 is supplied to a hot water tap 5 through a hot water supply pipe 4. The main body control device 6 controls the heating means 1 and controls the temperature of hot water discharged from the heat exchanger 2. Remote control device 10
is connected to the main body control device 6 in a path, and exchanges data with each other by data transmission using packet exchange. The exchange of data is transmitted to the other party when the operating state of the water heater 3 changes or when the right to set the hot water temperature or the setting is requested. FIG. 2 is a block diagram of the remote control device 10. The receiving circuit 11 converts the received waveform into data and inputs it to the microcomputer 12. The transmitting circuit 13 converts the transmitted data from the microcomputer 12 into a waveform and transmits it as a transmitted waveform.The display means 14 displays the operating status of the water heater 3 and the temperature of hot water discharged based on the data sent from the main body control device 6. Display settings. The setting means 15 requests and sets the right to set the hot water temperature, and also prohibits the right to be set. The notification means 16 uses a piezoelectric buzzer or the like to notify the transfer of the setting right for a certain period of time.
If it is desired to prohibit the transfer of the setting right, the setting means 15 must be operated.

An embodiment of the remote control device 10 is shown in FIG. 3, and the operation of the water heater of the present invention will be explained. When the water heater 3 is ready for operation, the power lamp 17 is turned on by data transmission from the main body control device 6 that instructs the power lamp 17 to turn on.

The combustion lamp 18 similarly lights up while the heating means 1 is burning;
The operating status of the water heater 3 is displayed. To set the hot water temperature, first check the priority lamp 19. If it is lit, you have the right to set it, so use the hot water temperature setting key 20 to set the current setting value based on the hot water temperature setting lamp. Set the setting value. If the priority lamp 19 is not lit, first press the priority key 22 to request setting rights, confirm that the priority lamp is lit, and then press the hot water temperature setting key 20.
operate.

Therefore, if the priority lamp 19 is not lit,
Even if the hot water temperature setting key 20 is pressed, no setting change operation is performed. The set value of the hot water temperature is displayed on the hot water temperature setting lamp 21, and the set value is updated only by the remote control device 1o that has the right to set it.

When the setting value of the main body control device 1 is updated, the setting value is transmitted to other connected remote control devices 10. Therefore, the hot water temperature setting lamps 21 of other remote control devices 10 also change to the changed value. Each remote control device 10 is provided with an address, and the main body control device 6 is connected to the remote control device 10.
0 is distinguished by address. When a setting right is requested from a remote control device 10 that does not have the setting right, the remote control device 10 that requested the setting right flashes the priority lamp 19. The remote control device 10, which had the setting right, flashes the priority lamp 19, and the notification means 1 for a certain period of time.
6 is activated, and the transfer of the setting right is announced with a sound. If the priority key 22 is pressed while the notification means 16 is working and A is in progress, the setting right will not be moved, and if the priority key 22 is not pressed within a certain period of time, the setting right will be moved and the setting right will be moved. The priority lamp 19 is turned on, and the other lamp is turned off. With this configuration, the hot water temperature can be set using a plurality of remote control devices 10, and other remote control devices 10 can be used during use.
Since the setting right is requested and it becomes possible to select whether or not to move the setting right, it is possible to prohibit the setting right from being transferred to another remote control device during use.

Effects of the Invention As described above, the water heater of the present invention provides the following effects.

(1) Each time the setting means of the remote control device sets the hot water temperature, it transmits the set value to the main body control device, and when the set value is updated, the main body control device transmits the set value to another remote control device. Since the temperature is transmitted, the hot water temperature can be freely set using multiple remote control devices.

(2) To transfer the setting right for the hot water temperature between remote control devices, before the setting right is transferred to another remote control device, a sound is given for a certain period of time, and if the setting means is operated within that time, the setting right is transferred. Since it is determined whether or not to move the remote control device, it is possible to prohibit the setting right from being transferred to another remote control device during use.
