にされている。2. Description of the Related Art A block diagram of a conventional example of this type of bath device with a bubble bath function is shown in FIG. 10 is a bathtub, and 20 is a bathtub. The bathtub 10 and the bathtub 20 are connected through circulation paths 31 and 32. The bathtub 10 has the circulation paths 31 and 3.
A circulation fitting 11 is provided to connect the bathtubs 2 to 2, and an air introduction pipe 12, which is a means for introducing air into the bathtub 10, is connected thereto. The bath pot 20 includes 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 to bypass the heat exchanger 23, and an orifice 25 is provided in the bypass passage 24, and a water volume switch 26 is provided on the heat exchanger 23 side. The bypass path 24
The orifice 26 is a heat exchanger 23 with a relatively small pipe diameter.
This is provided in order to reduce the water pressure (water amount) burden imposed by the pump 21 on the heat exchanger 23 and to send a stable amount of water to the heat exchanger 23. When a certain amount of water flows to the heat exchanger side, the water amount switch 26 is turned on and the burner 22 is ignited.

。[Problems to be Solved by the Invention] However, with the above-mentioned conventional bath device with a bubble bath function, no major problem occurs if the piping constituting the circulation paths 31 and 32 is not very long. When the piping of the circulation paths 31 and 32 becomes long, such as when the bathtub 20 is installed on the first floor, the following problems occur. ■When reheating a bath, if the piping is long, the resistance of the entire passage will increase and the amount of water to the heat exchanger will decrease, resulting in the water amount switch 26 not turning on and the burner 22
may become unable to burn. ■When operating a bubble bath, if the piping is long, the circulation flow rate is small and the bypass passage 24 is restricted by the orifice 25, so the force of the air-mixed water that is ejected into the bathtub 10 is weak, making it insufficient for a bubble bath. I can't give you that feeling.

The purpose is to provide equipment.

A bath device with a bubble bath function, which includes at least a circulation pump, an air introducing means for mixing air into the circulating water discharged into the bathtub, and a bypass path provided to bypass the heat exchanger. A water flow control valve is provided in the bypass passage, and the water flow control valve is fully opened during bubble bath operation, and during reheating operation, the water flow control valve provided on the heat exchanger side is opened until the water flow rate switch is turned on due to an increase in water flow. The present invention is characterized in that the water flow control valve is configured to automatically reduce the water flow from a fully open state.

Also, when reheating, the water volume control valve in the bypass passage is throttled until the water volume switch on the heat exchanger side is turned on.
Compared to the case where an orifice is provided, the necessary amount of water can be supplied to the heat exchanger to ignite the burner even for sufficiently long piping, and reheating operation can be performed normally.

ようにしている。A controller 70 has a built-in microcomputer, receives information from sensors in various parts of the apparatus, and commands from a remote controller (not shown), and issues predetermined operation commands to each part of the apparatus. In the present invention, when a bubble bath operation is commanded from a remote controller (not shown), the controller 70 issues a fully open command to the water flow control valve 27 of the bypass passage 33. On the other hand, when reheating operation is commanded from the remote controller, the controller 70 controls the water volume control valve 27 until the water volume switch 26 detects a water volume above a certain level and outputs an on signal. An operation command is issued to narrow down the opening degree from the fully open state.

Now, 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 reheating operation or an ON command for bubble bath operation (step 101), and in the case of a bubble bath, The circulation pump 21 is turned on (step 102), and on the condition that there is water circulation detected by a pressure sensor (not shown) installed in the bath return pipe 31, etc. (step 103), a command to fully open the water flow control valve 27 is issued. (step 104).

An instruction is given to narrow down the engine from the fully open state (step 114). That is, the servo motor of the water flow control valve 27 is driven to automatically gradually reduce the opening degree from the fully open state. During that time, the controller 70 waits for a switch-on signal from the water volume switch 26 (step 115), stops throttling the water volume control valve 27 when the water volume switch 26 is turned on (step 116), and issues an ignition command to the burner 22. .

ステップ１２０）、運転が停止される。As the opening degree of the water volume control valve 27 is decreased, the amount of water distributed to the heat exchanger 23 side increases.
Even if the total amount of water is relatively small, reheating can be performed normally by increasing the amount of water to the heat exchanger 23 side. In extreme terms, if the total amount of water exceeds a certain amount of water required to turn on the water amount switch 26, reheating becomes possible. Therefore, even if the piping becomes longer and the amount of circulating water decreases somewhat, reheating can be performed normally. Note that if it is determined in steps 104 and 113 that there is no water circulation, a safe operation is commanded (
Step 120), the operation is stopped.
