BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bubble bath device having a function of generating bubbles in a bathtub by circulating water using a pump.

0002

2. Description of the Related Art A conventional bubble bath device is shown in FIG. That is, hot water in the bathtub 1 is sucked by the pump 2 and is jetted into the bathtub 1 from the flow path outlet 3. At this time, the amount of air blown out is adjusted by the air suction mechanism 4. As a result, a bubble water stream is ejected from the channel outlet 3. On the other hand, in order to increase the temperature of the water inside the bathtub 1, the heating channel 5 is connected to the bathtub 1.
2-12522).

[Problems to be Solved by the Invention] However, in the conventional configuration described above, the number of bubble water jetted from the flow path outlet 3 is 3 to 5.
There was a problem in that the bubble diameter was only 1 mm and there was no function to change the bubble diameter. In addition, since there was only one type of bubble, the product quality was somewhat unsatisfactory.

Furthermore, there is no function for filling the bathtub 1 with hot water, and it cannot be said that the bathtub 1 is necessarily user-friendly. The present invention solves the above problems, and provides a bubble bath device that has a function of generating bubbles of 3 to 5 mm and fine bubbles of several tens of micrometers from one jet nozzle, and that automatically fills the bath with hot water. It is intended for this purpose.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a bath, a bath heat exchanger for heating water in the bath, and a variable bubble diameter jet ejection device provided in the bath. a circulation circuit configured to communicate with each other to circulate water in the bath; a circulation pump disposed in the circulation circuit;
The hot water supply pipe has one end connected to the circulation circuit and the other end connected to the outlet side of the hot water supply heat exchanger.

[0006]

[Function] With the above-described configuration, the present invention provides a
To generate bubbles and microbubbles of several tens of microns,
By switching the variable bubble diameter jet ejection device, it is possible to vary the bubble size. Additionally, in order to automatically fill a bath with hot water, hot water from a heat exchanger for hot water supply is passed through a circulation circuit through a hot water supply pipe, thereby automatically filling the bath with hot water.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIGS. 1 and 2, 7 is a bath heat exchanger, and the bath heat exchanger 7 and the bubble diameter variable jet ejection device 9 provided in the bath 8 are composed of an outgoing pipe 10 and a return pipe 11. It is piped by a circulation circuit 12. Further, a circulation pump 13 is disposed in the return pipe 11 . On the discharge side of this circulation pump 13, there is a heat exchanger 14 for hot water supply.
A hot water supply pipe 16 is piped from the outlet side of the tank via a solenoid valve 15. The configuration of the variable bubble diameter jet ejection device 9 provided in the bath 8 will be explained. A jet nozzle 17 is provided downstream of the outgoing pipe 10, and an air pipe 18 is provided downstream of the jet nozzle 17. This air pipe 18 is connected to air control valves 19, 20. Further, a flow path area switching valve 21 is provided downstream of the air pipe 18. This flow path area switching valve 21 includes a through flow path 22,
and a reduced channel 2 to which a porous body 23 such as a wire mesh is attached.
4, and is configured to be switched by a motor 25. 26 is a mixing nozzle, and 27 is a suction port from the bath 8. Reference numeral 28 denotes an operation panel for setting the water temperature and amount of water. A controller 29 controls the electromagnetic valve 15, the circulation pump 13, the air control valves 19 and 20, the motor 25, and the like. 30 is hot water supply Karan, 31
is an arrow indicating a flow, and 32 and 33 are bubbles.

Next, the operation of the above configuration will be explained. First, the automatic filling operation of the bath 8 will be explained with reference to FIG. 1. When the amount of hot water to be supplied to the bath 8 and the temperature of the hot water are set on the operation panel 28 and the operation switch (not shown) is turned on, the solenoid valve 15 is opened. The hot water discharged from the hot water supply heat exchanger 14 flows through the circulation circuit 12 and is supplied to the bath 8 from the variable bubble diameter jet ejection device 9. When the supply amount reaches the set value on the operation panel 28, the solenoid valve 15 is closed and automatic filling is completed.

Next, the operation when bubbles of 3 to 5 mm are generated will be explained with reference to FIG. At this time, the operation panel 28
When a bubble switch (not shown) is turned on, the circulation pump 13 is operated, and the hot water discharged from the circulation pump 13 is squirted out from the spout nozzle 17. The ejected jet shears the air that has flowed into the air pipe 18 via the air control valve 19 and is ejected into the bath 8 as bubbles of 3 to 5 mm. At this time, the flow path area switching valve 21 is on the through flow path 22 side,
Bubbles are ejected without any resistance. next,
The operation of generating microbubbles of several tens of microns will be explained with reference to FIG. At this time, when a bubble switch (not shown) on the operation panel 28 is turned on, the motor 25 is operated and the pore body 23 of the flow path area switching valve 21 is moved to face the jet nozzle 17 . Further, the air control valve 19 is in a closed state, and the air control valve 20 is in an open state. A flow passage restricting portion is provided on the air control valve 20 side. In this state, the circulation pump 13
is operated and a jet is ejected from the ejection nozzle 17,
The jet shears the air from the air pipe 18 and cuts it by 0.5 mm.
Erupts as small bubbles. The ejected bubbles further collide with the pore body 23. As a result, the bubbles of about 0.5 mm are reduced to fine bubbles of several tens of microns by the porous body 23. These fine bubbles are ejected from the mixing nozzle 26 and make the hot water inside the bath 8 cloudy.

In this embodiment, two types of bubbles can be generated with one circulation pump, resulting in low cost.
