フローしたりすることが発生する問題があった。In the above-mentioned conventional bath device, the forced circulation pump 6 is driven during the dropping water supply to the bathtub, so that the dropping pipe 7 is connected to the hot water storage heating can body 2. The water level A in the drop pipe 7 becomes considerably lower than the water level B in the bathtub 1 due to the suction force.
However, on the other hand, when the driving of the forced circulation pump 6 is stopped at the same time as the water supply is stopped, the drop pressure due to the stop of the water supply is canceled, and the suction force of the water in the drop pipe 7 toward the inside of the can body 2 is canceled. Presence of depressurized state in the drop hopper 8,
Also, the compressed air accumulated in the hot water storage type heating body 2 is returned and expanded to the side of the drop pipe 7 and the atmospheric pressure applied to the water surface of the bathtub 1 acts at the same time, resulting in the pump. After the stop of 6, the water level in the drop pipe 7 suddenly and largely reacts, and a backflow from the drop pipe 7 into the drop hopper 8 occurs, so that the water from the drop hopper 8 having a volume much smaller than the downstream capacity is discharged. There was a problem that would overflow.

む。Since the general structure of the bath apparatus of the embodiment is the same as that described in the section of the prior art,
The description is omitted. The configuration of the drop hopper 8 in this embodiment will be described with reference to FIG. 2. FIG. 2 shows a state in which water is being supplied to the bathtub 1. The receiving container portion 10 provided in the upper part of the device is a solenoid on-off valve V1 for dropping hot water and hot water from the hot water supply passage U1 and the water supply passage U2, respectively.
Water is received via the electromagnetic on-off valve V2. A drop-in port 11 is opened at the center of the bottom of the receiving container part 10, and a drop-in outer cylinder body 20 is connected to the drop-in port 11 so as to communicate therewith. The drop-in outer cylinder body 20 has a hopper shape in which the lower portion is thin. This drop outer cylinder
An inner cylinder 30 is arranged in a double-tube shape with a proper gap S formed between the inner cylinder 20 and the outer cylinder 20. The upper opening of this inner cylinder 30
The numeral 31 is located right below the drop-in port 11 and allows most of the water injected from the drop-in port 11 to flow into the inner cylindrical body 30. That is, the inside of the inner cylinder 30 serves as the main passage for water injection. The inner tubular body 30 has a lower portion that is narrowed to form a double cylindrical tube concentric with the outer tubular body 20. The drop pipe 7 is connected to the double cylindrical pipe. The water that has flowed out of the apparatus from the lower end opening of the inner cylinder 30 flows into the hot water storage heating can body 2 through the drop pipe 7.

Is provided. A normally open spring-biased diaphragm valve 50 is provided facing the overflow port 21 from the outside. The normally open spring urging diaphragm valve 50 normally opens the overflow port 21 by the urging spring 51. A pressure chamber 60 is provided behind the normally open spring-biased diaphragm valve 50, and the pressure chamber 60 is connected to a side portion of the receiving container 10 by a pressure introduction passage 61.

Since part of the water injection is not drawn into the pressure chamber 60 and the pressure chamber 60 is not pressurized,
The diaphragm valve 50 is overflowed by the biasing spring 51.
Keep 21 open. Therefore, in this state, when there is a backflow from the downstream side water supply passage L, the backwashed miscellaneous water is surely discharged from the overflow port 21, and the backflow to the upstream side water supply passages U1 and U2 above it. Do not reach

At this time, due to the momentum of the flow rate flowing out from the inner cylindrical body 30, the gap S between the inner cylindrical body 30 and the outer cylindrical body 20, which is the sub passage, is in a negative pressure state. Further, a part of the water injected from the receiving container portion 10 is drawn into the pressurizing chamber 60 through the pressurizing introducing passage 61, and the pressurizing chamber 60 is pressurized by this, and the diaphragm valve 50 resists the spring 51 and overflows. Press to 21. The pressing force and the suction force due to the negative pressure state of the gap S act on the diaphragm valve 50, so that the diaphragm valve 50 surely closes the overflow port 21 and the overflow during water injection is reliably prevented. Further, the overflow port 21 can be reliably closed even when the amount of injected water is small. Therefore, leakage of water can be prevented and air can be mixed reliably from a large flow rate to a small flow rate.

の状況は従来の場合と同様である。The operation of supplying water to the bathtub in this apparatus is shown in FIG.
Referring also to the description, when the water supply switch to the bathtub (not shown) is turned on, the controller 9 causes the controller 9 to supply water from the water source (not shown) to the hopper 8 via the water supply passage U2. The on-off valve V2 is opened and the driving of the forced circulation pump 6 is started. The water thus supplied enters the hot water storage type heating can body 2 from the dropping hopper 8 through the dropping pipe 7. By driving the forced circulation pump 6, part of the water that has entered the hot water storage heating can body 2 from the bathtub 1 through the outflow pipe 3 is sucked into the forced circulation pipe 5, and the forced circulation pipe 5 It is discharged vigorously to the return pipe 4 side through the inside. The negative pressure generated by this draws the water in the hot water storage heating can body 2 toward the return pipe 4, so that the bath water is forcedly circulated through the outflow pipe 3, the hot water storage heating can body 2, and the return pipe 4. . By this forced circulation, the water in the dropping pipe 7 is also sucked and quickly dropped into the hot water storage heating can body 2. Further, the forced circulation causes the inside of the bath 1 to be agitated, and the temperature can be made uniform. The above situation is the same as the conventional case.

が、例えば2秒とすることができる。According to the present invention, when the predetermined drop into the bathtub 1 is completed and the water supply switch is turned off, the controller 9 issues a command to close the water drop electromagnetic on-off valve V2, and a fixed delay time t 1 is also applied thereto. Then, it issues a drive stop command to the forced circulation pump 6. The driving of the forced circulation pump 6 is stopped at the delay time t 1 after the water supply is stopped. Therefore, the water drop solenoid valve V2
A large rise in the water level of the drop pipe 7 due to the closing of the valve is prevented because the forced circulation pump 6 is continuously driven. On the other hand, when the drive of the forced circulation pump 6 is stopped later, since the water supply is already stopped, the factor of increasing the water level generated when the water supply is stopped is no longer added, and the water level of the drop pipe 7 is still largely increased. Does not occur. The constant delay time t 1 is set in advance as the time until the water level rise accompanying the closing of the water drop solenoid valve V2 is terminated after the closing command of the water drop solenoid on-off valve V2 is issued, or the cause thereof is resolved. It can be obtained by an experiment, but can be set to 2 seconds, for example.
