。Turn on the power. Furthermore, the automatic operation switch (22) is turned on, the drop-in shutoff valve (19) is opened, and a constant rate of 1 tqs (for example, 10ffi) is applied so that the water level from the hot water supply circuit (I7) is below the discharge port (9). Hot water in the bathtub (1
), the drop-in shutoff valve (19) is closed, the pump (5) is operated, and the water flow switch (13) performs a circulation judgment to determine the presence or absence of residual water. After the determination, the pump (5) is stopped +h. The circulation judgment is that if there is hot water in the bathtub (1) that is equal to or greater than the outlet (9), it is determined that there is water, and if it is less than or equal to the outlet (9), it is determined that there is no water. If there is water J, it is determined that there was water left in the bathtub (1), and for example, the trial run is stopped and a message such as "check message" is issued. If the circulation judgment is r that the water is hot, then the shutoff valve is dropped again. (19
) is opened, and a certain amount of hot water (for example, 801) is dropped into the bathtub (1) from the hot water supply circuit (17).Next, the drop-in stop valve (19) is turned on to determine the circulation according to (13). If the result of the circulation determination is "no water", Q++ (204! to 401) of hot water is further poured into the bathtub 1) from the hot water supply circuit (17), and the circulation determination is repeated again.

される。If the result of this circulation determination is also "no water", for example, there is a possibility that the drain plug of the bathtub (1) is open, so the trial run is stopped and a "check message" or the like is output. If the circulation judgment is "water present", hot water is filled above the discharge port (9), so when the pump (5> is operated at the time of circulation judgment), the hot water flows through the circulation circuit (3). 4) is circulated and the air in the circuit is expelled.Also, after the circulation judgment becomes "water present", there is hot water in the bathtub (1) at or above the outlet (9). , the pressure sensor (15) is in a state where the water amount can be detected (P≧PI).
If it is determined that there is water, the reference water level (bottom of the bathtub) is detected.

The amount of water Q = (qo +ql) or (qo +q+ +q11) dropped in step 1) is stored in a control unit (not shown).

i4御部に記憶される。Open the shutoff valve (19) and drain the hot water supply circuit (17) from the bathtub (
1) A certain amount of hot water qz (for example, 201 to 40e) is dropped into the tank, and a rise in the water level before and after dropping q2 of hot water is detected by a pressure sensor (15). However,
At Obe, the cross-sectional area of the bath [(1) 5 = qz/h is calculated from the water volume q2 and the water level rise, and furthermore, the water volume Q + q
By dividing t by the cross-sectional area S of the bathtub, the depth hx from the water level after q2 hot water supply to the bottom of the bathtub is determined. The cross-sectional area S is stored in the i4 control section.

る。On the other hand, although the cross-sectional area of the bathtub (1) differs depending on the type of bathtub, the depth of the bathtub (1) is almost constant (
(approximately 550 m), so if you use the bottom of the bathtub as a reference, you can determine the distance Ho to the appropriate set water level LS. For example, Ho should be 450 m or slightly deeper) This Ho is numerical data. (e.g. R
(OM) is stored in the ti control unit. Now, the bathtub (1) is filled with hot water from the bottom to a water level of hX, so the hot water of Q3=(H6hx)XS - (He h^ )Qz/h is poured into the bathtub (1). If the water is dropped into the hot water supply circuit (17), hot water can be filled up to the set water level LS.When the above additional water! 11

このようにして浴槽(1)に場が張られた後入浴する。After the bathtub (1) is filled in this way, the person takes a bath.

この信号によりポンプ(5)が運転せられると、浴場は
吸入口(12)より戻り管(4)に吸い込まれ、ポンプ
(5)より吐出された後、バイパス通路(7)と熱交換
器(2)とに分流される。When the pump (5) is operated by this signal, the bath water is sucked into the return pipe (4) from the suction port (12), and after being discharged from the pump (5), it passes through the bypass passage (7) and the heat exchanger ( 2) It is divided into two parts.

空気管(10)により空気が吸い込まれ、噴流中に気泡
となって浴槽(1)内に噴出される。Most of the circulating flow flows into the bypass passage (7). This is because if the entire flow is allowed to flow through the heat exchanger (2), there will be a large resistance, the heat exchanger (2) will become large, and furthermore, corrosion may occur due to the flowing water. The bath water joins together again and is ejected into the bathtub (1) from the outlet (9) through the outgoing pipe (3).When the solenoid valve (11) is opened here, the discharge flow causes the air pipe (10) to eject into the bathtub (1). Air is sucked in and ejected into the bathtub (1) as bubbles in the jet stream.

人体に当たっても熱くない。When reheating is performed next, the capacity IIIrB circuit (6) operates the pump (5) at a small capacity. Of the discharge flow from the pump (5), the flow that flows to the heat exchanger S (2) is transferred to the heat exchanger (
2) is heated. This flow rate is set to about IO1/min due to the above-mentioned problems such as corrosion. The heated bath merges with the bath that has passed through the bypass passage (7),
The temperature is lowered and the liquid is discharged from the discharge port (9). This discharge stream does not get hot even when it hits the human body.

Since the field is filled with , the main control circuit (61) is in phase! 4 control circuit (62) outputs 100% output immediately after driving! 4.
一方、落とし込み時の循環判定の場合は、浴槽(1)に
湯がないことがあるのでポンプ(5)の吐出流量が序々
に増加するようにtilgIする。On the other hand, in the case of determining the circulation at the time of dropping, there may be no hot water in the bathtub (1), so tilgI is performed so that the discharge flow rate of the pump (5) gradually increases.

。That is, the main 1Am circuit (61) inputs the output of the pressure sensor (15) when the pump (5) starts operating, and if the pressure sensor (15) does not detect "r water present", the soft start circuit ( 63). The soft start circuit (63) prevents the pump (5) from stepping out and locking for a time T (for example, 1 second) after the start of driving, and adjusts the phase angle to 100% in order to obtain starting torque.

ンプ(5)は実際には序々に動き始め、吐出流量も序々
に増加する。Then, after T time, the phase angle is set to a value X smaller than 100% from the state where the pump (5) is rotating, and is gradually increased. By setting the phase angle in this manner, the pump (5) actually starts to move gradually, and the discharge flow rate also increases gradually.
従って、ポンプ(5)内や配管(3)・ (4)内に残

飛び散ることはない。Therefore, the water remaining in the pump (5) and the pipes (3) and (4) is gradually discharged into the bathtub (1) and does not splash out violently.
尚、本実施例では、ポンプ(5)のl4FBを位相i制
