For example, the water is automatically filled to the set temperature until the water level switch detects it. That is, in operation, the water solenoid valve 1 is first opened, and when the water heater switch 12 detects running water, the hot water gas burner 2 is ignited, and the hot water heat exchanger 3 replaces the combustion heat with water. Hot water is supplied to the bathtub 13. In other words, filling the water with hot water is started. When the water level switch 4 detects the required liquid level, the water electromagnetic valve 1 is closed and the supply of hot water, that is, the filling of hot water is stopped. At this time, an electric control circuit (not shown in the figure) installed in the appliance controls the gas amount of the hot water gas burner so that the temperature does not exceed the set temperature based on the signal from the hot water temperature detector 5 at the outlet of the hot water heat exchanger 3.

器具とは別置されるのが一般的である。 When the water solenoid valve 1 closes, the pump 6 on the bath side starts operating, and hot water in the bathtub flows to the water intake port 13a.
From there, the circulation begins via the bath water switch 7, the bath temperature sensor 8, and the bath heat exchanger 9, and then returns to the bathtub from the discharge port 13b. At this time, when the bath temperature detector 8 detects the water temperature set in the controller, the operation of the pump 6 is stopped, and if the set water temperature is not reached and the bath water switch 7 is ON, the bath After igniting the gas burner 10 and reheating it until it reaches the set water temperature, turn on the bath gas burner 10.
extinguish the fire and stop pump operation. Note that the hot water temperature detector 5 and the bath temperature detector 8 are generally thermistors. Further, the solenoid valve 1 and the water level switch 4 are generally placed as one unit separately from the equipment due to the relationship between the mounting positions of the water level switch.

的である。 FIG. 3 is a block diagram showing the conventional water amount sensor system, in which components having the same functions as those in FIG. 4 are given the same reference numerals as in FIG. 4. The operation is the fourth
If "the water level switch 4 detects the required liquid level" explained in the figure is replaced with "the water amount sensor 11 detects the required amount", it is exactly the same, so a detailed explanation will be omitted. That is, the only difference is that the water level switch method detects the height of the liquid level in the bathtub, whereas the water flow sensor method detects the amount of hot water filled. However, in Fig. 4, it was stated that the solenoid valve 1 and the water level switch 4 are generally placed separately from the appliance as one unit, but in the case of the water flow sensor 11 in Fig. 3, they are incorporated into the appliance. It is common that

The advantage of the above-mentioned water level switch method is that the amount of hot water can be correctly stopped at the required water level regardless of the presence or absence of residual water in the bathtub and the level of the remaining water. This has the disadvantage that the construction work is expensive and complicated because it has to be installed separately. In addition, the water sensor method is easy to install because the water sensor can be incorporated into the fixture, but the user has to check whether there is any remaining water in the bathtub and the amount of remaining water if there is any remaining water. If the count is not corrected each time, there is a problem that the hot water may overflow from the bathtub or the water level may be lower than the required level.

式に従つて残水量Q1（）を演算させる。 When a signal enters the pump drive circuit 19, relay K1
is excited, the contact SW 1 is closed, the pump 6 is operated, sucks the remaining water from the water intake port 13a of the bathtub, passes through the bath water switch 7, the bath temperature sensor 8, and the bath heat exchanger 9 to the discharge port 13b. A circulation circuit is formed for residual water to be returned from the tank to the bathtub 13. At this time,
Bath running water switch 7 remains ON even after a certain amount of time has passed.
If not, the bath calculation circuit 18 determines that there is no remaining water in the bathtub, reads out the total amount of hot water required, and fills the bathtub with hot water. Meanwhile, bath water switch 7 is ON.
Then, the remaining water temperature t 1 (°C) is detected by the bath temperature detector 8, and this is taken into the bath calculation circuit 18.
Next, while this circulation continues, a signal is output from the bath calculation circuit 18 to the timer circuit 21, which relays the signal.
K 4 is energized, contact SW 4 of the bath proportional valve 25 is closed, and the bath gas burner 10 is burned for a certain specific time T (hr) set in the timer circuit 21, after which the residual water temperature t 2 (℃) has increased. is detected by the same bath temperature detector 8, and the remaining water amount Q 1 () is calculated in the bath calculation circuit 18 according to the following equation.
Ｑ＝Is×Ｔ×η／１×（t2−t1） ……(1)式 ここでIs（kcal／hr）……風呂のインプツト Ｔ（hr）……特定燃焼時間 η（％）……熱効率 Q1（）……浴槽の残水量（＝Kg） t1（℃）……浴槽の残水温度 t2（℃）……特定燃焼時間後の浴槽の残水温度 １（kcal／Kg℃）……水の比熱 である。 Q = Is × T × η / 1 × (t 2 - t 1 ) ...Equation (1) where Is (kcal/hr) ... Bath input T (hr) ... Specific combustion time η (%) ... ...Thermal efficiency Q 1 () ...Residual water amount in the bathtub (=Kg) t 1 (℃) ...Residual water temperature in the bathtub t 2 (℃) ...Residual water temperature in the bathtub after specific combustion time 1 (kcal/Kg) ℃)...It is the specific heat of water.

は、風呂温度検知器８で計側されるため、これら
のデータを(1)式に代入すると自ずと浴槽の残水量
Q1（）が算出できる。 Here, the input Is (kcal/hr) of the bath is fixed by the equipment, and strictly speaking, the thermal efficiency η (%) varies somewhat depending on the temperature, etc., but it is not so much that it becomes a problem in practical use. Can be fixed at a constant value. Furthermore, the specific combustion time T (hr) is kept constant by the timer circuit 21, and the residual water temperature in the bathtub t 1
(℃), residual water temperature t 2 (℃) after specific combustion time T (hr)
is measured by the bath temperature sensor 8, so by substituting these data into equation (1), the amount of remaining water in the bathtub is automatically calculated.
Q 1 () can be calculated.
いま、風呂のインプツトIs＝10000（kcal／hr）
熱効率＝80（％）、特定燃焼時間Ｔ＝１／60（hr）と
すると、(1)式は、
Q1（）＝133／t2−t1 ……(1)′式
となり、即ち、定数をt2−t1の温度差で割る形と
なる。 Now, bath input Is = 10000 (kcal/hr)
Assuming thermal efficiency = 80 (%) and specific combustion time T = 1/60 (hr), equation (1) becomes Q 1 () = 133/t 2 - t 1 ...(1)' equation, that is, The constant is divided by the temperature difference t 2 − t 1 .

ツチ１２が閉となつて湯張りを開始する。 Once the remaining water amount Q 1 () is calculated, the next required water amount Q 2
( ) (generally 180 = fixed value), Q 2 −
After Q 1 () is calculated by the bath calculation circuit 18, a signal is input to the water solenoid valve drive circuit 23, relay K 2 is energized, and the double contact SW operates the water solenoid valve 1 and the hot water supply proportional valve. 2 is closed, a signal is sent from the bath calculation circuit 18 to the hot water supply proportional control circuit 22, and the user turns on the hot water temperature control switch 15.
A command is issued to control the temperature at a temperature slightly lower than the bath boiling temperature set in (for example, about 2 degrees Celsius lower), the water solenoid valve 1 is opened, the hot water supply running water switch 12 is closed, and hot water filling begins. do.

The bath pump 6 starts operating, and hot water in the bathtub starts circulating from the water intake port 13a, via the bath water switch 7, the bath temperature detector 8, and the bath heat exchanger 9, and returns to the bathtub from the discharge port 13b. At this time, when the bath temperature detector 8 detects the water temperature set in the controller, the operation of the pump 6 is stopped, and when the water temperature is, for example, 2 degrees Celsius lower than the set temperature, and the bath water switch 7 is turned on, the bath water is heated.
