Also, the operation control circuit (30) of the water heater (3) operates based on the signal from the main remote control (1), and the bathtub temperature is almost set. hot water is supplied from the water heater (3) to the bathtub (4).

After that, the user presses the hot water supply switch (32) on the sub remote control (2) to supply hot water, for example, in the kitchen while the user is in operation to fill the hot water supply.
When turned on, the second microcomputer (21) operates based on a signal from the hot water supply switch (32). And the second
Based on the signal from the microcomputer (21), the temperature displayed on the hot water supply set temperature display (25) switches from the hot water supply set temperature to the bathtub set temperature (hot water filling temperature) and blinks. Therefore, the user of the kitchen knows that hot water is being filled and that the temperature of the hot water being supplied has been set to the same temperature as the bathtub temperature setting. Then, hot water at the set temperature of the bathtub is supplied from the hot water faucet (9). After that, when the bathtub water level reaches the set water level and the bathtub temperature reaches the set temperature by the subsequent reheating operation, the first microcomputer (10) operates and the water heater (
3) outputs a signal to the operation control circuit (30). Then, the operation control circuit (30) is activated, the hot water filling operation is stopped, and the combustion of the water heater (3) is also stopped. Water heater(
When the combustion of step 3) stops, the first microcomputer (10) operates based on the signal from the operation control circuit (30), and the temperature displayed on the hot water setting temperature display (25) changes from blinking to lighting. The water supply temperature will change to the set temperature.

For example, when the user turns on the hot water filling switch (11) because the user uses water in the bathtub while taking a bath and the water level has dropped, the hot water filling operation is started. The bathtub temperature and bathtub water level are displayed on the bathtub temperature display (12) and bathtub water level display (14) of the main remote controller, respectively.

For example, if the user takes a shower (7
) on the main remote control (1).
32), the first microcomputer (10) operates based on the signal from the hot water supply switch (32), and the water supply setting temperature display (13) operates based on the signal from the first microcomputer (10). changes to display the bathtub temperature setting and starts blinking. Hot water at approximately the bathtub temperature is supplied from the shower (7).

Thereafter, when the bathtub water level reaches the set water level and the hot water temperature in the bathtub reaches the set temperature, the first microcomputer (10) operates and outputs a signal to the operation control circuit (30) of the water heater (3). Then, the operation control circuit (30) is activated, the hot water filling operation is stopped, and the combustion of the water heater (3) is also stopped. Then, based on the signal from the water heater (3), the first
The microcomputer (10) operates and the water supply setting temperature display (13)
) will stop flashing, and the display (13) will stop blinking.
The set water temperature is displayed.

Also, when a user turns on the hot water switch (32) of the sub-remote controller (2) in the kitchen and is using hot water supplied from the water heater (3), another user may When the hot water supply switch (11) of the remote control (1) is turned on, the first microcomputer (10) operates. and,
Based on the signal from the first microcomputer (10), the water heater (3
) operation control circuit (30) operates, and hot water at approximately the bathtub setting temperature is supplied from the water heater (3) to the bathtub (4). or,
The second microcomputer (21) operates based on the signal from the first microcomputer (10), and the hot water setting temperature display (2) of the sub remote controller (2) operates based on the signal from the second microcomputer (21).
5) The displayed temperature switches to the bathtub set temperature and starts blinking.

After that, when time passes and the hot water filling operation stops and the water heater (3) stops burning, the second microcomputer (21) operates based on the signal from the water heater (3) and displays the hot water setting temperature. The blinking of the temperature displayed on the display device (25) stops, and the set temperature for hot water supply is displayed on the display device (25).

According to the embodiment of the present invention, when the user turns on the hot water filling switch (11) and fills the hot water,
When the user turns on the hot water supply switch (31) or (32), the bathtub set temperature has priority over the hot water supply temperature, so even when the hot water supply switch (31) or (32) is turned on, hot water is not filled. The operation can be continued to supply hot water at the bathtub set temperature to the bathtub (4), and the bathtub (4) can be filled with hot water at approximately the set temperature. Also, the hot water switch (
If the hot water filling switch (11) is turned on while hot water is being supplied based on the setting of 32), the set temperature of the bathtub takes precedence over the set temperature of the hot water supply, and hot water at the set temperature of the bathtub is supplied. The hot water can be supplied to the bathtub (4), and the bathtub (4) can be filled with hot water at approximately the set temperature.

Furthermore, when the user turns on the hot water supply switch (32) of the sub-remote controller (2) during hot water filling operation, the temperature displayed on the hot water supply set temperature display (25) changes from the hot water supply set temperature to the bathtub set temperature. , the temperature display will flash,

In addition, if a user turns on the hot water supply switch (32) to supply hot water, and another user turns on the hot water supply switch (11) of the main remote control (1) in the bathroom, the secondary Hot water setting temperature display (2) on the remote control (2)
Since the displayed temperature in step 5) switches to the bathtub setting temperature and the temperature display blinks, the user can know that the hot water filling operation has started and that hot water at the bathtub setting temperature will be supplied. In addition, the temperature displayed on the hot water setting temperature display (13) of the bathroom main remote control (1) switches to the bathtub setting temperature and the temperature display blinks, so the bathroom user can also control the hot water faucet (6) and the shower. (From 7>, you can know that hot water at the bathtub setting temperature is being supplied. Also, the hot water setting temperature display (13) and (25) indicates that hot water filling operation and hot water supply operation are being performed at the same time. Since the remote controllers (1) and (2) are also used as a display device, the configuration of each remote controller (1) and (2) can be simplified.

In the above embodiment, when the hot water supply switch (11) or (24) is turned on and the hot water supply switch (31) or (3
2) turns on the hot water supply temperature display (13),
(25) Switch the displayed temperature to the bathtub setting temperature,
Although the temperature display is made to blink, for example, the main remote control (1) and the sub remote control (2) are provided with light emitting bodies such as light emitting diodes, and the hot water supply switch (11) or (24) is turned on and the hot water supply switch (31) is turned on. Alternatively, by turning on or blinking the light emitting body by turning on (32), the same effect as in the above embodiment can be obtained.

(g) Effects of the invention The present invention is a remote control device configured as described above,
If the hot water supply switch and the hot water supply switch installed on a remote control other than this hot water supply switch are turned on, the hot water supply temperature setting has priority over the hot water supply temperature setting, so the hot water supply switch will not be turned on during hot water filling operation. When the hot water supply switch is turned on and the hot water supply switch is turned on, hot water at the set temperature can be supplied to the bathtub, and as a result, hot water filling operation and hot water supply operation are performed. Even if both are performed at the same time, the bathtub can be filled with hot water at approximately the set temperature.

In addition, by providing a remote control with a hot water supply switch with a display that shows a different display depending on whether the hot water supply switch and the hot water supply switch are on or when either one of the switches is on, it is possible to The person who turns on the hot water switch and uses hot water can know from the display that the hot water supply operation is being performed and hot water at the set temperature is being supplied. It is possible to distinguish changes in water from those caused by a malfunction of a water heater, etc.

In addition, a hot water supply setting temperature display is provided on the remote control having the hot water supply switch, and this hot water supply setting temperature display shows different indications depending on whether the hot water filling switch and the hot water supply switch are on or when either one of the switches is on. Therefore, the user can know from the above-mentioned display that hot water filling operation and hot water supply operation are being performed at the same time, and can also know that hot water at approximately the set temperature is being supplied. The set temperature display can be used both as a temperature display and as a display for notifying that hot water filling operation and hot water supply operation are about to be performed at the same time, and the configuration of the remote control can be simplified.

In addition, when the hot water supply switch and hot water supply switch provided on one remote control are on, the hot water supply setting temperature takes precedence over the hot water supply setting temperature, so even if the user turns on the hot water supply switch and the hot water supply switch, Hot water at approximately the set temperature is supplied to the bathtub, and the bathtub can be filled with hot water at approximately the set temperature.

Furthermore, by providing a display on the remote control that displays differently depending on whether the hot water supply switch and hot water supply switch are on, or when either switch is on, the hot water supply operation can be improved. When the hot water supply switch is turned on in the paper, the user can know from the display that hot water at the set temperature will be supplied.
