(2) Remote control device under the condition that there is cold residual water inside
When the operation switch (19) of (18) is turned on, the pump (P) is driven and the output of the water flow switch (F) is judged. Then, when the water flow switch (F) is outputting an ON signal, that is, it is judged that the residual water in the bathtub (2) circulates in the reheating circuit (21) to bleed the circuit. In that case, stop the pump (P) and switch the switching valve (25) to switch the hot water supply circuit (27) → switching valve (25) → heat exchanger for reheating (22)

At the same time as closing, the switching valve (25) is switched to establish the reheating circuit (21). In addition, the gas burner for reheating (23) is burned and the pump (P) is driven so that the temperature inside the bathtub detected by the temperature sensor (40) reaches the set temperature (for example, 40 ° C). Boil up. This completes the filling operation when the cooled residual water stays in the bathtub (2).

らである。However, in the above-mentioned conventional apparatus, the water level in the bathtub (2) at the completion of the filling of water is the remote control device (18).
There was a problem that high precision water filling could not be performed due to deviation from the set water level set in. This is because the water level detected by the water level sensor (41) changes depending on the temperature of the water in the bathtub.

ある。The above cause will be described in more detail. The water level detecting portion of the water level sensor (41) is composed of a pressure sensitive element whose resistance changes with pressure. The resistance value of the pressure sensitive element also changes depending on the ambient temperature. To do. That is, the output of the pressure-sensitive element that comes into contact with the water in the bathtub circulating in the reheating circuit (21) changes depending on the temperature of the water in the bathtub, and the detected water level fluctuates.

Will not match. Therefore, the set water level set by the remote control device (18) is set by the output value of the water level sensor (41) in the state of the set temperature, so that cold residual water is replenished with warm water and the water level sensor (41) Even if the detected water level matches the set output value, the water level in the bathtub (2) at this time will deviate from the set water level, and high-precision water filling cannot be performed.

差が生じる。Another cause of impeding high-precision filling of water is a change in the specific gravity of water due to a change in temperature. That is, the specific gravity of the water in the bathtub in the low temperature state before heating the bathtub (2) and the water in the bathtub after heating the bathtub (2) are different, and the water level changes before and after the heating. Therefore, when the water level sensor (41) detects the set water level before heating the inside of the bathtub (2), it matches the water level in the bathtub (2) after heating the bathtub (2) to the set temperature. It will not be done. Especially when the water heater (1) and the bathtub (2) are installed separately on the first and second floors of the building, the height difference between the water level sensor (41) installation part and the bathtub (2) becomes large. There is a large error in the water level.

れにより湯張り動作を停止させる。That is, in this case, when the residual water stays in the bathtub (2), the water temperature in the bathtub (63) is judged prior to the water level judgment (step of the drawing code (70)). The steps are executed and thereafter, as will be described later, after heating the inside of the bathtub (2) to the set temperature, hot water of the set temperature is supplied to the set water level to the set temperature. (D). When it is confirmed that the temperature inside the bathtub (2) is lower than the set temperature when the step of the above-mentioned drawing code (63) is executed, that is, it is judged that there is cold residual water in the bathtub (2). In this case, the water level in the bathtub once detected by the water level sensor (41) is further judged, and the water in the bathtub (2) becomes
It is judged whether or not the safe water level is 5 cm or more from the part (standard water level H0 described above) (see step of drawing code (64)). When the water level in the bathtub is less than or equal to the safe water level, the amount of hot water supplied to the bathtub (2) measured by the flow rate counter (Q) inserted upstream of the hot water supply heat exchanger (26) is 10 liters. Open the hot water filling valve (28) and burn the hot water supply gas burner (24) so that only 10 liters of hot water at the set temperature set by the remote control device (18) is tub (2).
(See step (65)). This raises the bath (2) to the safe water level. (E). Next, the gas burner (23) for reheating is combusted and the pump (P) is driven (see step of reference numeral (67)), and the temperature in the bathtub (2) detected by the temperature sensor (40) is the remote control device. The combustion of the reburning gas burner (23) is continued until the set temperature set in (18) is reached (reference numeral (68)).
See step). When the temperature in the bathtub (2) detected by the temperature sensor (40) is raised to the set temperature, the gas burner (23) for additional heating is extinguished and the pump (P) is stopped (see reference numeral (69)). See step). As a result, the temperature of the water level sensor (41) that changes its output depending on the temperature (contacts the water in the reheating circuit (21) to detect its water pressure) is maintained at the set temperature, and thereafter remains constant. Under the temperature conditions, the hot water replenishment operation described below is performed while detecting the water level in the bathtub. (F). Next, determine the water level in the bathtub detected by the water level sensor (41) (see step of drawing code (70)), and if the water level in the bathtub is equal to or higher than the set water level set by the remote control device (18),
The control operation is moved to the step of drawing code (63) for judging the temperature in the bathtub (2) again. Conversely, if the water level in the bathtub is lower than the set water level, the control operation is moved to the step of drawing code (71). Then, the shortage of hot water in the bathtub (2) is replenished. That is,
Burning the hot water gas burner (24) and switching valve (25)
By switching the hot water supply circuit (27) → heat exchanger for reheating (22) → water flow switch (F) → a circuit connected to the bathtub (2) is established, and the opposite circuit, that is, the hot water supply circuit (27 ) To the state where the circuit connected to the water level sensor (41) is cut off. As a result, the water level sensor (41) can detect the water level in the bathtub. Also, open the hot water filling valve (28) and put hot water at the set temperature in the bathtub (2).
(See step (71)). (Ki). Next, the water level sensor (41) monitors the water level in the bathtub (refer to the step in the drawing code (72)), and when it reaches the set water level, the hot water gas burner (24) is extinguished and the water filling valve (28) is closed. , The switching valve (25) is switched and the reheating circuit (2
1) is established (see the step of the reference numeral (73)), whereby the filling operation is stopped.

If judged, the operation of driving the pump (P) is repeated after hot water is supplied to the bathtub (2) in units of 10 liters, and the water flow switch (F) outputs an ON signal when the pump (P) is driven. At this time (when air bleeding of the circuit connecting the water level sensor (41) to the bathtub (2) is completed), the water level sensor (41) monitors the water level in the bathtub in the same manner as above, and this becomes the set water level. Continue the filling operation until.
