In the water level setting sequence, hot water is automatically supplied to a water level above the connection port of the circulation circuit of the bathtub, and the output of the water level detecting means at that water level is stored in a storage means such as a microcomputer. To automatically supply hot water to a water level above the connection port of the circulation circuit of the bathtub, for example, supply hot water little by little, perform a forced circulation operation in the circulation circuit each time, and determine whether or not a water flow is generated in the circulation circuit.
When the circulating water flow continues for a predetermined period of time, it can be detected that the water level has reached a level higher than the connection port.

である。By executing the water level setting sequence, hot water is automatically supplied to the reference water level, and the reference output of the water level detection means is automatically stored, and the increase in the output of the water level detection means for a 1α rise in water level is a known value. From this, you can easily set the desired water level by seeing how many times above or below the desired water level is above the standard water level. When the switch is turned on, a normal automatic hot water supply sequence is executed, and hot water is automatically supplied until the output of the water level detection means reaches the set output value.

循環判定）。The present invention enables the setting and memorization of the reference water level and output value to be performed automatically without any special operation by the user, and after the installation is completed, the power cord (not shown) of the device body (1) is connected. After being inserted into a power outlet, the water level setting sequence is executed and the reference output of the pressure sensor (12) is memorized when the user first commands automatic hot water supply. That is, as shown in Fig. 2, after the power is turned on, the operation switch (17) is turned on and the main body (1)
When the automatic operation switch (18) is turned on for the first time, the three-way switching valve (5) connects the tank (4) and the outgoing pipe (6), and the bypass solenoid valve (1
4) is opened, the pump (7) is driven, and the water heater (B)
Approximately 101 water is supplied to the return pipe (11) via the outgoing pipe (6) and the bypass pipe (13), and the circulating circuit (A
) is discharged into the bathtub (2) and wIm circuit (A)
is washed away with water. Next, connect the three-way switching valve (5) to the outgoing pipe (6)
and the return pipe (11), and the bypass solenoid valve (
14) and forcefully circulate the water in the circulation circuit (A) (
(circulation judgment).

い、そして再び循環判定を行なう。At this time, if the water level (old) is up to the connection port of the circulation circuit (A) in the bathtub (2), the flow rate sensor (8) will continue to detect the water flow, and if there is no water remaining at the water level (old) , that is, the bathtub (2
), the water flow will no longer be detected when the water in the circulation circuit (A) is sent to the bathtub (2). If it is determined that there is no water remaining up to the water level (old), the outgoing pipe (6) and return pipe (1
1), fill the bathtub (2) with 10% water, and perform the circulation determination again.

ながら往管（６）を通して浴槽（２）に給湯を行なう。In this way, a small amount of hot water is supplied and the circulation judgment is repeated, and if the flow sensor (8) detects the water flow continuously for a predetermined period of time in the circulation judgment and it is judged that the water level of the bathtub has reached the water level (old), the water flow goes out again. (6) and the return pipe (11) from both the bathtub (
2) 101! The circulation port of the bathtub (2) is completely immersed in water, and the air in the return pipe (11) is particularly ensured to be discharged. In this embodiment, the pressure transmitted from the return pipe (11) is measured by the pressure transmitted from the return pipe (11) to the output (P3) that is 30 scratches higher than the output (P2) of the pressure sensor (12) at the current bath water level (H2). ), hot water is supplied to the bathtub (2) through the outgoing pipe (6).

From there, only the outgoing pipe (6) is used to supply hot water, and the return pipe (,11) is used to supply hot water.
is used as the pressure detection tube of the pressure sensor (12). Then, when the output of the pressure sensor (12) reaches P3, the hot water supply is stopped, additional heating is performed to the temperature set in the temperature setting section (19), and the output (P3) of the pressure sensor (12) is set to the reference value. It is stored in the memory in the controller (15) as a.

。On the other hand, if it is determined that there is already water remaining at the water level (Hl) in the first circulation determination, 10% water is poured into the bathtub (2) using both the outgoing pipe (6) and the return pipe (11). The water level 101 higher than that water level is used as the standard.

That is, first, water was poured into the bathtub (2) from both the outgoing pipe (6) and the return pipe (11) to exhaust the air inside the pipe, and then a circulation judgment was made and it was determined that the water level was not up to the circulation port. If it is determined that the water level is up to the circulation port, hot water is supplied only from the outgoing pipe (6) and the pressure sensor (
12) detects the pressure based on the water level of the bathtub, and the pressure sensor (
When it is determined that the output of 12) has reached the set output value corresponding to the water level set in the water level setting section (20), the hot water supply is stopped;
It reheats the fire to the set temperature.

Since the water level setting sequence is executed, the user can memorize the standard output value of the pressure sensor (12) by simply turning on the automatic operation switch (18) in the same way as usual, without having to do any special operations. After that, you will be able to freely set the water level to your preference.

In other words, in devices with built-in water level detection means, the standard output value of the water level detection means can be set by the user without any special operations, just by turning on the automatic operation switch. This can be done with the help of a manual, which prevents erroneous operations. Further, since the water level setting sequence is executed when the automatic operation switch is turned on for the first time when the power is turned on, no problem will occur even if the memory of the reference output is lost due to a power outage or the like.
