[Detailed description of the invention] (b) Industrial application fields The present invention relates to an air intake structure for a bubble generating bathtub.

(b) Conventional technology Conventionally, as a basic form of a bubble-generating bathtub, Japanese Patent Laid-Open No. 59-1
As described in Publication No. 35058, a bath water circulation flow path consisting of a bath water suction pipe and a bath water supply pipe is interposed between the bathtub body and the circulation pump, and the bath water forced delivery pipe is An air intake part is provided in the middle.

With this structure, when the circulation pump sucks the bath water inside the bathtub body through the bath water suction pipe, and when the pump spouts the bath water into the bathtub body through the bath water supply pipe, the bath water is Utilizing the negative pressure created by the gushing of hot water,
Air is mixed into the bath water from the air intake part, and the bath water mixed with air bubbles is ejected into the bathtub body.

A plurality of independent air intake chambers are provided inside the air intake section by disposing a vertical partition wall, and each air intake chamber is connected to each jet nozzle via an air intake pipe.

(c) Problems to be Solved by the Invention However, the air intake section of the above-mentioned bubble-generating bathtub has the following drawbacks.

That is, in order to prevent leakage of air from the intake chamber, the air intake section fixes each partition wall to create a circular flow of air, thereby mixing air into the bath water.

However, over a long period of time, dirt accumulates on the partition walls, but because each partition wall is glued together, it is not possible to easily remove the partition walls and remove the dirt, making it very unsanitary. It has become.

Moreover, when this dirt accumulates, the flow of air in the intake chamber is obstructed, resulting in the problem that air cannot be mixed smoothly into the bathing water.

An object of the present invention is to provide an air intake structure for 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 vibrator and a bath water forced delivery pipe is interposed between the bathtub body and the circulation pump, and the bath water is The end of the forced-feeding pipe is opened into the bathtub body to form a plurality of jetting nozzles, and an air intake part is connected to the bathwater circulation flow path, and the bubble-mixed bathwater is delivered from the nozzle to the bathtub body. In a bubble-generating bathtub configured to be able to eject air,
The inside of the air intake section is divided into a plurality of independent intake chambers by a vertical partition wall, each intake chamber is connected to a jet nozzle via an intake pipe, and the longitudinal partition wall is detachably attached to the air intake section. The present invention provides an air intake structure for a bubble-generating bathtub characterized by the following.

Further, the present invention is characterized in that a vertical partition wall is fitted onto the inner surface of the air intake portion via a sealing material.

(E) Functions and Effects In the present invention, by operating the circulation pump to forcefully circulate the bath water, the bath water is spouted from the spout nozzle provided in the bathtub body, and at this time, the ejector function is activated from the air intake part. The air taken in by air entrainment due to the swirling flow is mixed into the bath water through the intake pipe, and a jet stream containing bubbles can be obtained.

By applying this jet to the desired parts of the body, shiatsu,
You can enjoy the pine surge effect caused by other jet pressures, and also have the functions of purifying your body and maintaining your health due to the ultrasonic action generated by the air bubbles.

In particular, in the present invention, since the vertical bulkheads forming each intake chamber are removably attached within the air intake section, the vertical bulkheads can be removed periodically to remove dirt, etc. The entrance part can be kept sanitary, and the flow of air can be improved, so that air can be mixed into the bath water smoothly.
