Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a bubble-generating bathtub in which the particle size of bubbles can be adjusted.

(B) Conventional technology Conventionally, as one type of bathtub, there is a bathtub equipped with an air bubble generator, which generates air bubbles in the bathtub, and the air bubbles perform pine surges on the body of the bather. That's what I do.

That is, such a bathtub is provided with a spout on the side wall of the bathtub,
A pump part that circulates bath water via a bath water circulation vibrator is connected to the spout, and an air intake part is attached near the spout.

When the pump is operated to eject bathwater from the spout of the bathtub, air is sucked into the bathtub under negative pressure to generate bubbles of a certain particle size within the bathtub.

(c) Problems to be Solved by the Invention However, the above-mentioned bubble-generating bathtub had the following drawbacks.

In other words, when bath water is ejected from the spout, the air sucked under negative pressure from the air intake becomes large bubbles in the bath water circulation pipe, and even if it is ejected into the bathtub, the air remains in the bathtub. There was a risk of it spreading inside.

Therefore, if the bubbles are large, even if the bubbles hit the body, they cannot stimulate the body, and in such a bubble state, effective pine surgery cannot be performed.

An object of the present invention is to provide a bubble-generating bathtub that can solve the above problems.

(d) Means for Solving the Problems In the present invention, a bath water circulation flow path consisting of a bath water suction flow path and a bath water forced flow path is interposed between the bathtub body and the circulation pump section. A jet nozzle is formed at the opening of the bath water forced flow channel provided in the bathtub body, and an air intake part is connected in communication with the bath water forced flow channel, and the bath water mixed with air is supplied from the nozzle to the bathtub body. In the bubble generating bathtub configured to be able to eject air bubbles, the bubble particle size adjusting means is provided in the bath water forced flow path, and the drive motor of the means is further controlled by an inverter to change the bubble particle size. The present invention provides a bubble-generating bathtub.

(e) Functions and Effects In the present invention, the circulation pump operates to circulate the bath water within the bath water body, thereby spouting the bath water from the spout nozzle, and at that time, the air sucked from the air intake part is It can be mixed into the bath water in the bath water forced flow channel to create air bubbles, and the air bubbles can be applied to various parts of the body to enjoy pine surge, etc.

Furthermore, when the bath water is spouted from the jet nozzle, the bubble particle size can be adjusted to any desired particle size, that is, from a large diameter to a small diameter, using a bubble particle size adjusting means provided in the bath water circulation forced flow path. I can do it.

In particular, in the present invention, since the drive motor of the bubble size adjusting means is controlled by an inverter, by freely changing the bubble size using the same means, the body is stimulated and pine surge etc. caused by the bubbles can be prevented. Can be done effectively.
