Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a bubble bath device that is provided with a bubble generator to generate bubbles in a bathtub.

(Prior art) As a conventional device of this kind, Utility Model Application No. 48-56153
There is a product shown in No. 1, but it was not possible to adjust the amount of foam.

The object of the present invention is to solve the above-mentioned conventional drawbacks and to provide a bubble bath device in which the amount of bubbles generated can be easily controlled remotely from within the bathroom.

(Example) Reference numeral 1 denotes a circulating bath pot installed outside a bathroom A, which is connected to a bathtub 2 through a connecting pipe 3, and circulates and heats the water in the bathtub 2. A pump 4 is connected to a suction pipe 5 and a discharge pipe 6 provided in the connecting pipe 3. Reference numeral 7 denotes a bubble generating section provided in the discharge pipe 6, which is provided with an air suction pipe 8 that communicates with the outside air, and sucks air using the negative pressure caused by the water flow to mix bubbles into the water. Reference numeral 9 denotes a remote controller installed on the bathroom wall 10, which is provided with an ignition handle 12 for opening and closing the ignition mechanism of the bathtub 1 via a wire 11, and a foam adjustment knob 13. One end of a shaft 14 is connected to the knob 13, and the other end of the shaft 14 penetrates the wall 10 and protrudes outside the bathroom, and a switch 15 for opening and closing the power source of the pump 4 is connected to the end of the shaft 14 to operate the pump. cam 16
and a foam amount adjusting cam 17 for operating a foam amount adjusting device to be described later. Reference numeral 18 denotes a bubble volume regulator, which includes a valve box 21 provided with an air suction hole 19 and an air adjustment hole 20, a needle-type valve 22 that faces the adjustment hole 20 so as to be able to move forward and backward, and a valve 22 that is connected to the adjustment hole 20. It has a spring 25 that is always pressed in the direction of separation. One end of the valve 22 is made to protrude outside the valve box 21 and come into contact with the bubble amount adjusting cam 17, and an O-ring 23 that closes the adjusting hole 20 is fitted into the valve 22. The cam 17 is formed with a required number of stepped portions that allow the valve 22 to be pushed in in stages to sequentially change the opening degree of the adjustment hole 20 to large, medium, small, and closed by the O-ring 23. 24 is a vinyl pipe that communicates the adjustment hole 20 with the air suction pipe 8 of the bubble generating section 7.

In this configuration, in order to use foam, it is enough to turn the foam adjustment knob 13, the pump operation cam 16 closes the switch 15 and the pump 4 is turned on, and the foam amount adjustment cam 17 pushes the valve 22 to open the adjustment hole 20.
Since the opening is set and maintained at a large degree, the bathtub water sucked in from the suction pipe 5 sucks in a large amount of air at the bubble generating section 7, and is ejected into the bathtub 2 from the discharge pipe 6 together with bubbles. At this time, the ignition handle 12 may be operated at the same point to ignite the bath pot 1, and reheating may also be used.

If you want to change the amount of bubbles, turn the knob 13 one after another, the valve 22 will be pushed in step by step by the cam 17, the opening degree of the adjustment hole 20 will change from medium to small, and the amount of bubbles will change accordingly. do. When the knob 13 is turned all the way, the valve 22 enters the adjustment hole 20 and closes the adjustment hole 20 with the O-ring 23, stopping bubbles and allowing only forced circulation.

Also, without using foam and with pump 4 stopped,
Of course, it is also possible to only reheat the bathtub 1.

(Effect of the invention) As described above, the present invention provides a bubble volume regulator that adjusts the amount of air sucked into the discharge flow from the pump using an air adjustment hole and a valve that changes the opening degree of the air adjustment hole. It is equipped with a foam control knob installed in the bathroom that operates a switch to open/close the power supply and change the opening degree of the above-mentioned valve using a single shaft. The amount of foam can be adjusted with a single knob, which is extremely convenient.
