Function: With the above-described configuration, the present invention constantly receives transmission signals between the water heater controller and the remote controller, displays them as bath information on the image display means, and, if necessary, transmits input data from the operation signal input means to the transmission circuit. By transmitting information over the information cable via the remote controller, bath information can be obtained by image display at any time other than where the remote controller is installed, and bath setting conditions can also be changed, greatly improving the usability of the water heater. .

Embodiments Hereinafter, embodiments of the present invention will be explained based on FIGS. 1 and 2.

FIG. 1 is a control block diagram of the bath monitor adapter 17 of the bath monitor control device of the present invention.

The information cable terminal 1 is connected to a monitor control means 19 for controlling the transmission/reception switching means 8 so that the transmission signal from an information cable (not shown) connected to the information cable terminal 1 is received by the reception means 4 and transmitted by the transmission means 3. There is. Also,
The information cable terminal 18 is configured to supply power to the power conversion means 13 to the internal circuit.

The monitor control means 19 is connected to select a character code from a galactor generator 20 that has already been converted into ROM from the transmission data sent via the receiving circuit 4 and send it to a CRTC (CRT controller) 21. CRTC
21 writes the character code from the monitor control means 19 into a VRAM (video RAM) 22 for configuring the screen, and also outputs the composite video signal 1 via a buffer 23.
- Connected to output from the video output terminal 24. Further, the monitor control means 19 controls the operation signal control means 25.
It is connected to set and change the boiling water level, boiling water temperature, boiling reservation time, etc.

FIG. 2 is a diagram showing the display configuration on the image display means 26 of the bath monitor control device of the present invention.

The bath monitor adapter 17 is connected to a video signal input terminal (not shown) of an image display means (a cathode ray tube television in FIG. 2) 26 so as to receive a video signal from a video output terminal 24 of the bath monitor adapter 17.

It is important to input the video signal to the image display means 26, and to set and change the boiling water level, boiling water temperature, boiling reservation time, etc. using the operation signal control means 27 (infrared wireless remote control in FIG. 2). It is configured. In this case, the operation signal control means includes the infrared light receiving section 28 of each of the image display means 26 and the bath monitor adapter 17.
Sends an infrared signal with a predetermined code to. However, since the transmission address code is changed by the mode changeover switch 29 of the image display means 26 (TV) and the bath adapter 17 (video), the infrared signal passes through only one of the infrared signal determination sections (not shown), resulting in interference. It has a unique structure.

Note that the same members as in FIG. 3 are given the same numbers.

In this system, the water heater controller 1 and the remote controller 12 normally transmit bath information such as the water level, water temperature, and presence or absence of a human body in the bathroom to each other using a predetermined communication procedure. In this state, one end of the information cable 11 is distributed and connected to the information cable terminal 18 of the bath monitor adapter 17. The bath monitor adapter 17 supplies power to its internal circuitry through the power conversion means 13, and also exchanges bath information with the transmission means 3 via the reception means and transmission/reception switching means 8 through the monitor control means 19.

First, the monitor control means 19 sends a necessary character code from the character generator 20 to the CRTC 21 in response to data received via the receiving means 4.

The CRTC 21 writes the received character code into the screen configuration VRAM 22, converts it into a composite video signal, amplifies the signal via the buffer 23, and outputs it to the video output terminal 24. Since the image display means 26 inputs the video signal from this video output terminal 24 through the attached video input terminal, it can be switched to the video mode when necessary by the mode changeover switch 29 of the operation signal control means 27. to get bath information. Further, in this state, the boiling water level, boiling water temperature, boiling time, etc. are changed by manual key input of the operation signal control means 27 as necessary. The data for this setting change is Bath Monitor Adapter 1.
The signal is inputted to the monitor control 19 via the infrared light receiving section 28 as the operation signal input means 25 of 7. Monitor control means 1
9 sends the setting change data to the information cape 1v via the transmitting means 3, the transmitting/receiving switching means 8, and the information cable terminal 18.
Send to 11.

Therefore, by distributing the bath information only between the water heater controller and the remote controller, and connecting it to the bath monitor adapter, it can be displayed on an image display means located at any location, and the image can be displayed using the operation signal control means. Settings can be changed while looking at the display, improving the usability of the water heater.

Furthermore, the present invention is not limited to the above embodiments,
The display output configuration from the monitor control means of the bath monitor adapter can be displayed on image display means other than the television by using a liquid crystal driver, a fluorescent display tube driver, or the like.

Effects of the Invention As described above, the bath monitor control device of the present invention is distributed and connected from an information cable, and displays transmitted data on an image display means via a receiving circuit in the same manner as the communication procedure between a remote controller and a water heater controller. The bath monitor adapter, which transmits input data from the operation signal input means onto the information cable via the transmission circuit, constantly receives transmission signals between the water heater controller and the remote controller, and displays the data as bath information on the image display means. By displaying and, if necessary, transmitting the input data by the operation signal input means to the information cape lV soil via the transmission circuit,
Bath information can be obtained by image display at any time other than where the remote controller is installed, and bath setting conditions can also be changed, which has the effect of greatly improving the usability of the water heater.
