ある。According to the present invention, the setting and storage of the reference water level and the output value can be automatically performed by the user without any special operation. After the construction is completed, the power cord (not shown) of the apparatus body (1) is After being inserted into the power outlet, the water level setting sequence is executed when the user first commands the automatic hot water supply, and the reference output of the pressure sensor (12) is stored. That is, as shown in FIG. 2, when the operation switch (17) is turned on after the power is turned on and the apparatus body (1) is in the operable state, and the automatic operation switch (18) is turned on, the reference water level (pressure If the reference output value of the sensor) is not stored, it is determined that the operation is the first automatic operation. First, the three-way switching valve (5) communicates the tank (4) with the forward pipe (6), and the bypass solenoid valve (14). Is opened, the pump (7) is driven, and about 10 liters of water is supplied from the water heater (B) to the return pipe (11) through the outward pipe (6) and the bypass pipe (13), and the circulation circuit (A The air in) is discharged into the bath (2) and the circulation circuit (A) is filled with water. Next, the three-way switching valve (5) is switched to the communication between the forward pipe (6) and the return pipe (11), the bypass solenoid valve (14) is closed, and water is forcedly circulated in the circulation circuit (A) (circulation determination). . At this time, the circulation circuit (A) is placed in the bathtub (2).
If there is a water level (H1) to the connection port of, the flow sensor (8) continuously detects the water flow, and if there is no remaining water at the water level (H1),
That is, when starting from the state where there is no water in the bathtub (2), the water flow is not detected when the water in the circulation circuit (A) is delivered to the bathtub (2). When it is determined that there is no residual water up to the water level (H1), the water heater (B) is used again for both the outflow pipe (6) and the return pipe (11) to enter the bathtub (2).
Perform l water injection, and then perform circulation judgment again. In this way, a small amount of hot water is supplied and the circulation judgment is repeated, and in the circulation judgment, the flow rate sensor (8) continues to detect the water flow for a predetermined time, and if it is judged that the bath water level has reached the water level (H1), the outgoing pipe is made again. From both (6) and return pipe (11) to bathtub (2)
Inject 10 liters of water to completely submerge the circulation port of the bathtub (2) and ensure that the air in the return pipe (11) is discharged. In this embodiment, the pressure transmitted from the return pipe (11) is set to the pressure sensor (12), with the output (P3) 30 cm higher than the output (P2) of the pressure sensor (12) at the bath water level (H2) at this point. The hot water is supplied to the bathtub (2) through the forward pipe (6) while being detected by. Ie bypass solenoid valve (14)
Is closed, hot water is supplied from the water heater (B) using only the forward pipe (6), and the return pipe (11) is used as the pressure detection pipe of the pressure sensor (12). When the output of the pressure sensor (12) reaches P3, the hot water supply is stopped, the temperature set by the temperature setting unit (19) is reheated, and the output (P3) of the pressure sensor (12) is used as the reference value. Is stored in the memory inside the controller (15).
一方、最初の循環判定で既に水位（H1）の残水が有ると
判定した場合には、往管（６）と戻り管（11）との両方
を用いて浴槽（２）に10lの注水を行ない、その水位よ
り10cm上位の水位を基準にするようにしている。On the other hand, if it is determined in the first circulation judgment that there is already residual water at the water level (H1), 10 l of water is poured into the bathtub (2) using both the forward pipe (6) and the return pipe (11). The water level is 10 cm above the water level.
而して圧力センサ（12）の基準出力（P3）を記憶して水
位設定のシーケンスを完了し、その浴槽水位（H3）を基
準水位として使用者は水位設定部（20）を操作し、好み
の水位に設定することができる。Then, the reference output (P3) of the pressure sensor (12) is memorized and the sequence of water level setting is completed, and the user operates the water level setting section (20) with the bath water level (H3) as the reference water level, It can be set to the water level of.

きするのである。When the automatic operation switch (18) is turned on for the second time after the power is turned on, the automatic hot water supply sequence as shown in FIG. 3 is executed, and the hot water is automatically supplied to the water level set by the water level setting unit (20).
The temperature is automatically set to the temperature set in the temperature setting section (19). That is, first, water was poured into the bathtub (2) from both the forward pipe (6) and the return pipe (11) to discharge the air in the pipe, and then the circulation was determined to determine that there was no water level to the circulation port. In that case, if an appropriate amount of hot water is supplied and it is determined by the circulation determination that there is a water level up to the circulation port, hot water is supplied only from the forward pipe (6) and the bath water level is measured by the pressure sensor (12) via the return pipe (11). When it determines that the pressure sensor (12) output has reached the set output value corresponding to the water level set by the water level setting unit (20), it stops hot water supply and reheats to the set temperature. .

Since the water level setting sequence is executed, the user can memorize the reference output value of the pressure sensor (12) just by turning on the automatic operation switch (18) as usual, without being aware of it. You can freely set the water level to your liking.

That is, in the case where the water level detecting means is built in the main body of the apparatus, the user sets the reference output value of the water level detecting means without any special operation by the same operation as a normal automatic hot water supply, that is, by simply turning on the automatic operation switch. It is possible to prevent the erroneous operation. Further, since the water level setting sequence is executed when the automatic operation switch is turned on for the first time after the power is turned on, there is no problem even if the reference output memory is lost due to a power failure or the like.
