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

In Fig. 1, ■ is a bathtub, 2 is a bathtub with a water heater, 3 is a connection between the bathtub 1 and the bathtub 2 with a water heater, and 2 is a bathtub with a water heater.
A circulation pipe that supplies hot water to the bathtub 1 and also circulates the bath water; 4 is a faucet used when hot water is used for showers, etc.; 5 is a remote control that controls the bathtub 2 with a water heater; 6 is a faucet. A hot water temperature setting device 7 sets the hot water temperature from 4 and the temperature of hot water supplied to the bathtub 1, 7 a hot water setting temperature display lamp that displays the temperature set by the hot water temperature setting device 6, and 8 a hot water temperature setting device 8 from the bath pot 2 with water heater. An automatic hot water supply switch starts supplying hot water to the bathtub 1 through the circulation pipe 3, and 9 is a water level setting device.
This is to set the water level of hot water supplied to the bathtub by the automatic hot water supply switch 5.

In FIG. 2, reference numeral 11 indicates a hot water temperature setting device input section that receives a signal from the hot water temperature setting device 6, and 12 indicates an automatic hot water supply switch 8.
The automatic hot water supply switch input section 13 is a temperature setting input switching section which receives the signal from the automatic hot water supply switch input section 12, and determines whether the signal from the hot water temperature setting device input section is the hot water temperature or the automatic hot water temperature. Switch. Reference numeral 14 denotes a set temperature limiter, which limits the temperature to within a certain temperature range when the temperature signal from the hot water temperature setter input section 11 inputted through the temperature setting input switching section 13 is not within a certain temperature range. 15
1 is an automatic hot water supply temperature storage unit; 16 is a hot water supply setting temperature storage unit; 1
Reference numeral 7 denotes a display temperature switching section, which transmits the set temperature data of the hot water supply set temperature storage section 16 or the automatic hot water supply set temperature storage section 15 to the next stage in response to a signal from the automatic hot water supply input section. Reference numeral 18 denotes a set temperature display section, which displays the set temperature data from the display temperature switching section 17 on the hot water supply set temperature display lamp 7.

The operation of the bathtub with water heater configured as described above will be described below.

When the automatic hot water supply switch 8 is OFF and the faucet 4 is closed,
The set temperature display lamp 7 displays the set value of the hot water temperature when the faucet 4 is opened. That is, since the automatic hot water supply switch input section 12 is OFF, the display temperature switching section 17 transmits the set temperature data of the hot water supply set temperature storage section 16 to the set temperature display section 18, so the set temperature display lamp 7 displays the hot water set temperature. .

Then, when the hot water temperature setting device 6 is pressed, the signal from the hot water temperature setting device input section 11 passes through the temperature setting input switching section 13 to change the data in the hot water setting temperature storage section 16, and the data changes the display temperature. Setting temperature display section 1 via section 17
8 and the set temperature display lamp 7 changes. and,
When the faucet 4 is opened, hot water is dispensed at that temperature. Further, even if the hot water temperature setting device 6 is pressed at that time, the above operation is repeated.

Next, when the automatic hot water supply switch 8 is turned on while the faucet 4 is closed, the set value of the hot water supply temperature to the bathtub 1 is displayed on the set temperature display lamp 7, and the hot water is sent from the bath pot 2 with a hot water heater through the circulation pipe 3. Hot water is supplied to bathtub 1.

That is, when the automatic hot water supply switch 8 is turned on, the temperature setting input switching section 13 and the display temperature switching section 17 are connected to the automatic hot water supply setting temperature storage section 15 side by a signal from the automatic hot water supply switch input section 12, and the automatic hot water supply setting is changed. The set temperature data in the temperature storage section 15 is transmitted to the set temperature display section 18 and displayed on the set temperature display lamp 7. Further, when the hot water temperature setting device 6 is pressed, a signal from the hot water temperature setting device input section 11 is transmitted to the setting temperature limiting section 14 via the temperature setting input switching section 13.
If the set temperature exceeds the limit value, the data in the automatic hot water supply set temperature storage section 15 is not changed. Therefore, no matter how much you press the hot water temperature setting device 6, it cannot be set above the limit value and the set temperature display lamp 7 does not change.

This is to limit the temperature during automatic hot water supply because the set temperature when using the faucet 4 for hot water supply is from low to high temperature, but high temperatures are unnecessary and dangerous for automatic hot water supply. It is.

Next, press the bathtub 1 until the water level is set using the water level setting volume 9.
When hot water is supplied, the supply of hot water from the bath pot 2 with a water heater to the bathtub l is stopped, the automatic hot water supply switch 8 is set to 0FFL, and a signal from the automatic hot water supply switch input section 12 causes the temperature setting input switching section 13 and the display temperature switch to be switched. The section 17 is the hot water supply setting temperature storage section 16
The temperature data in the hot water supply set temperature storage section 16 is transmitted to the set temperature display section 1B, and the set temperature display lamp 7 displays the contents of the hot water supply set temperature storage section 16. That is, the temperature returns to the set value of the hot water temperature when the faucet 4 is opened.

Effects of the Invention As described above, according to the bathtub with water heater of the present invention, since it serves both as a setting device for the temperature of hot water supplied to the bathtub and a setting device for the temperature of hot water supplied from the faucet, there is a dedicated device for automatically setting the hot water temperature. Since a setting section is no longer required, costs can be reduced. Additionally, since the set temperature for the automatic hot water supply temperature and the set temperature for the hot water supplied from the faucet are displayed on the same set temperature display section, the actual temperature of the hot water coming from the water heater can be seen at a glance. And since it also doubles as a temperature setting device, it becomes a simple and easy-to-use remote control.
