The circulating water level of the circulating metal fitting is set to be equal to or higher than the circulating water level. After the confirmation circulation determination is performed, when the water level is dropped from the reference water level to the set water level, the bottom area of the bathtub is calculated from the dropped water amount and the water level difference. Then, after the second water filling operation, when the inflection point of the output value of the bath water level sensor was detected, the bathtub bottom area obtained during the first water filling operation was multiplied by a constant water level difference. The amount of water is dropped. Then, after the circulation determination is made, a drop is made from the reference water level to the output value of the bathtub water level sensor corresponding to the set water level. In the method of the present invention, in the filling operation after the second time, the constant amount of water dropped after the inflection point of the output value of the water level sensor is detected,
Since it is the amount of water in consideration of the bottom area of the bathtub, whatever the volume of the bathtub, it is possible to set the reference water level to a slightly higher water level at which the circulation hole of the bathtub circulation fitting is submerged.
It is possible to accurately control the filling water level to the set water level.

Drop it (S2). During this time, the controller 60 monitors whether or not the flow rate of the drop per unit time is equal to or more than a certain level, based on the information from the drop water amount sensor 45a (S3). In the case of the embodiment, for example, the water pressure is 1.3 Kgf /

落とし込むことになる。When the flow rate per unit time is above a certain level (Yes in S3), the controller 60 adopts the inflection point detection mode as the control flow. In other words, at that point, both of the above-mentioned transportations are finished, and the drop in the bathtub is returned to the bath.
From the pipe 21 through the bath outflow pipe 22, the bathtub circulation fitting 11
While performing the single-sided conveyance performed through the inner pipe 11b of the (S
4) The controller monitors the detection output value of the bath water level sensor 52 and detects the inflection point of this detection output value (S5).
This is because the inflection point, the tub water level H is becomes a level H c reaching the outer tube 11a of the circulating fitting 11, so coming pressure is applied by bath water level to the wind Lu return pipe 21, tub water level sensor The detected output value of 52 changes in a situation different from the output curve up to that point, that is, a change such that the detected output curve is significantly increased. The starting point of this change is the inflection point.
When the inflection point is detected (Yes in S5), it can be estimated that the water level has reached about the water level H c , and this time, the water level H 1 just beyond the circulation hole of the circulation metal fitting 11 is determined. Therefore, a constant amount of water is dropped into the bathtub 10 by both transportations.

That is, it is determined whether or not the automatic water filling operation is the first time (S6), and in the case of the first automatic water filling operation (Yes in S6), a fixed amount of water determined from the beginning is dropped in both conveyances (S7). . This constant amount of water is determined in advance as a constant amount of water suitable for a large-sized bathtub so that the water level can be reheated and circulated beyond the circulation hole of the bathtub circulation fitting in any of bathtubs having different volumes. In this case, since the size of the circulation hole of the circulation fitting 11 is almost constant regardless of the size of the bathtub, the water level to be raised is almost constant. On the other hand, in the case of the automatic filling operation after the second time (No in S6), the bath bottom area obtained in the first operation is used, and the water level considering the size of the circulation hole of the circulation fitting 11 is used for this. This amount is dropped as a constant amount of water multiplied by the difference (S8).

After confirming the above, the water level is assumed to be a constant reference water level H 1 and the reference water level H 1 is stored. The output value of the bath water level sensor 52 at this time is set and stored as the reference output value P 1 (S14). The confirmation circulation judgment (S1
In the step 3), the air purging operation for eliminating the air in the circulation circuit 20 is also performed. That is, the three-way valve 51 is switched to complete the reheating circulation circuit 20 and the circulation pump 54 is driven in a strong state to circulate the bath water in the circulation circuit 20. Confirm that the bath water flow switch 55 is turned on for a certain period of time to confirm the circulation.

Until both are detected, both transportations are carried out (S15, S16), and the drop hot water solenoid valve 46b is closed (S17). When the solenoid valve 46b is closed, it is determined whether the operation is the first time (S18). If the operation is the first time, the bath bottom area S is calculated and the obtained value is stored (S19). The calculation of the bathtub bottom area S is performed by the water level sensor 52 in step S14.
After setting the reference output value P 1 of the (S15) to both transport darken, and quantity Q which dropped into until the water level sensor 52 detects the output value P S, the output value P S and P 1
And a water level difference corresponding to the difference, S = Q ÷ (P S -P 1)
Can be obtained at Bath bottom area S calculated and stored
Is the step S8 in the automatic filling operation after the second time.
In, the bathtub bottom area S is provided by multiplying by a constant water level difference. This constant water level difference is a value that takes into consideration the diameter of the circulation hole of the circulation fitting 11, and is set in advance. Since the diameter of the circulation hole of the circulation fitting 11 is almost constant regardless of the size of the bathtub 10, for example, a dimension about the diameter of the circulation hole can be adopted as the constant dimension hole. A value obtained by multiplying the bathtub bottom area S by a constant water level difference may be calculated and stored in step S19.

As the control flow, adopts the circulation determination mode in which the circulation is actually performed and the presence or absence of the circulation is determined. That is, after completing both the above-mentioned conveyance, first, the three-way valve 51 is switched, and the circulation pump 54
Is driven to determine whether the bath water circulates in the circulation circuit 20 (S9). And usually (when there is no residual water),
Since the bath water level is insufficient for circulating water, a constant amount of water is further transported (S10), and both transportation and circulation judgment (S
11) and are repeated until the circulation determination is OK. When the circulation determination is OK, a certain amount of water is dropped as a precaution (S12), and then a confirmation circulation determination is made (S13). Subsequent operations S14 to S19 are the same as those already described. Even in the circulation determination mode, it is possible to use the bathtub bottom area S obtained at the first time of the automatic filling operation to similarly obtain the dropped water amount in step S12 after the second time.

When a point is detected, a predetermined amount of water is dropped
Circulating bathtub with the circulation hole of the circulation fitting submerged
The water level at that time and the confirmation circulation judgment are performed.
I am trying to get the reference output value with the reference water level as
The reference value is the detected value at the inflection point where variations easily occur.
Circulation fittings that provide more stable values than when using
A value at a water level that exceeds
It can be a value. Moreover, the air is confirmed by the circulation check.
-Use the value of the bath water level sensor after purging
As a standard value
You can get it. In addition, the drop of a certain amount of water after the inflection point is detected by dropping a predetermined amount of water as the amount of water that can be reheated and circulated even in a large bathtub at the first time of the water filling operation. After the second time, the amount of water obtained by multiplying the bottom area of the bathtub calculated when performing the first filling operation by a constant water level difference was dropped, so even if the bathtub has any volume, It is possible to set the water level slightly above the submersion of the circulation hole of the bathtub circulation fitting as the reference water level, and to accurately control the water filling level to the set water level.
