2. Description of the Related Art FIG. 3 shows a block diagram of a conventional example of a bath device with a seed bubble bath function. 10 is a bathtub and 20 is a bath kettle. Circulation paths 31 and 32 connect between the bathtub 10 and the bath hook 20. The bathtub 10 has the circulation paths 31, 3
A circulation fitting 11 for connecting the two is provided, and an air introduction pipe 12 which is a means for introducing air into the bath 10 is connected. A circulation pump 21,
A burner 22 and a heat exchanger 23 are provided, and the heat exchanger 23
A bypass passage 24 is provided so as to detour around, the orifice 25 is provided in the bypass passage 24, and a water amount switch 26 is provided on the heat exchanger 23 side. The bypass 24
And the orifice 26 are the heat exchanger 23 having a relatively small pipe diameter.
It is provided to reduce the load of water pressure (water amount) on the pump 21 and to send a stable water amount to the heat exchanger 23. When a certain amount of water or more flows to the heat exchanger side, the water amount switch 26 is turned on and the burner 22 is ignited.

However, in the above-described conventional bath apparatus with a bubble bath function, if the pipes forming the circulation paths 31 and 32 are not so long, no serious problem occurs, but the bathtub 10 is placed on the second floor. When the pipes of the circulation paths 31 and 32 are long, such as when the bath kettle 20 is installed on the first floor, there are the following problems. When the bath is heated, if the piping is long, the resistance of the entire passage increases and the amount of water to the heat exchanger decreases. As a result, the water amount switch 26 does not turn on and the burner 22
Will not be able to burn. In the bubble bath operation, if the piping is long, the circulation flow rate is small and the bypass passage 24 is throttled by the orifice 25. Therefore, the force of the air-mixed water jetted into the bathtub 10 is weak, which is sufficient for the bubble bath. I can't give it a sensation.

Reference numeral 70 denotes a controller, which has a built-in microcomputer, receives information from a sensor of each part of the device and a command from a remote controller (not shown), and issues a predetermined operation command to each part of the device. Further, in the present invention, when the bubble bath operation is instructed from a remote controller (not shown), the controller 70 issues a fully open instruction to the water amount control valve 27 of the bypass passage 33. On the other hand, when the reheating operation is instructed from the remote controller, the controller 70
Until the water amount switch 26 detects a water amount above a certain level and outputs an ON signal, it issues an operation command to the water amount control valve 27 in a direction of narrowing the opening degree from the fully open state. .

Referring to FIG. 2 as well, the control operation by the controller 70 during the reheating operation and the bubble bath operation will be described. When the operation switch is turned on by a remote controller (not shown), the controller 70 determines whether the ON command is an ON command for additional heating or an ON command for bubble bath operation (step 101). The circulation pump 21 is turned on (step 102), and on condition that there is water circulation detected by a pressure sensor (not shown) provided in the bath return pipe 31 or the like (step 103),
A command to fully open the water amount control valve 27 is issued (step 104).

On the other hand, if it is determined in step 101 that the water is reheated, the controller 70 turns on the circulation pump 27 (step 112) and the water is circulated (step 113). Is commanded to narrow down from the fully open state (step 114). That is, the servomotor of the water quantity control valve 27 is driven to gradually and gradually decrease the opening degree from the fully opened state. In the meantime, the controller 70 waits for a switch-on signal from the water amount switch 26 (step 115), stops narrowing down of the water amount control valve 27 when the water amount switch 26 is turned on (step 116), and issues an ignition command for the burner 22. .

When the opening degree of the water quantity control valve 27 is decreased, the quantity of water distributed to the heat exchanger 23 increases, so that
Even if the total amount of water is relatively small, by increasing the amount of water to the heat exchanger 23 side, reheating can be performed normally. Extremely speaking, if the total amount of water is equal to or more than a certain amount of water required to turn on the water amount switch 26, reheating is possible. Therefore, even if the piping becomes long and the amount of circulating water decreases to some extent, reheating can be performed normally. When it is determined that there is no water circulation in steps 104 and 113, a safe operation is instructed (step 120) and the operation is stopped.
