[Detailed description of the invention] (A) Industrial application field The invention relates to the structure of the operation part of the bubble generating bath.

(B) Conventional technology Conventionally, as an embodiment of a bubble generating bath, a bath hot water circulation channel is interposed between a bathtub body and a circulation pump, and an air intake unit is connected to the bath hot water circulation channel. In some cases, hot water mixed with air bubbles can be ejected into the bathtub body, and the number of rotations of the hot water mixed with air bubbles can be adjusted by controlling the rotation speed of a circulation pump by a control unit.

Then, an operation unit having a built-in electric circuit unit is fixedly mounted on the wall surface of the bathroom, and the operation unit can be used to perform an operation of adjusting the ejection amount of the bath water mixed with bubbles.

Further, the air intake section is attached to the edge of the bathtub body separately from the operation section.

(C) Problems to be solved by the present invention However, in the case of the operation unit described above, since the operation unit is mounted on the wall surface of the bathroom, when operating the operation unit, the bather is in a position where the hand reaches to the operation unit. There is a problem that the user has to be close to the bathtub, and in some cases, the user has to operate out of the bathtub body, so that the user cannot perform the operation in a relaxed bathing posture.

(D) Means for solving the problem In the present invention, a bath water circulation channel is provided between the bathtub body and the circulation pump, and an air intake section is connected to the bath water circulation channel. In a bubble-generating bathtub capable of jetting hot water mixed with air bubbles into the bathtub body, the upper end of the air intake section is attached to the edge of the bathtub body by opening the upper surface, and the upper end of the air intake section is opened. An operation unit provided with an operation switch for giving an operation signal to each driving unit of the bubble generating bath is mounted in a closed state, and an air intake hole is formed in the operation unit, and air in the bathroom is supplied from the air intake hole. Is provided in the air intake section.

Further, according to the present invention, the air intake portion includes an intake case having an upper surface opening and a connector housing case, the upper surfaces of both cases are closed by an operation portion, and the air intake hole formed in the operation portion and the intake air are formed.

At the top opening of the air intake section, an operation section provided with an operation switch for giving an operation signal to each drive section of the bubble generating bath is mounted in a closed state, and an air intake hole is formed in the operation section. Since the air in the bathroom can be taken into the air intake section through the air intake hole, the bather can reach out to operate the operation section while keeping the bathing posture, and at the same time, operate the operation section with the air intake. It can also be used as a lid for the entrance, and both can be compactly attached to the edge of the bathtub body.

In addition, since the operating portion is only attached to the edge of the bathtub body so as to protrude upward, and the air intake portion is attached in a downwardly hanging state, unevenness formed on the edge can be reduced. As a result, dirt and the like hardly accumulate, the cleaning property can be improved, and the aesthetic appearance can be improved.

According to the second aspect of the present invention, the air intake portion includes an intake case having an upper surface opening and a connector accommodating case, and the upper surfaces of both cases are closed by the operation portion to form an air intake hole formed in the operation portion. And the above-mentioned intake case, and
Since the lead wire connected to the operation unit is connected to the connector housed in the connector housing case, when removing the operation unit from the air intake unit, remove the lead wire from the connector housed in the connector housing case. It can be easily removed.

Further, when the operation unit is attached to the air intake unit, a lead wire can be connected to the connector in advance, and then the operation unit can be attached so as to close the upper opening of the air intake unit.

As described above, since the connector is accommodated in the connector accommodating case provided in the air intake section, electrical connection and disconnection processing of the lead wire can be easily performed, and from this point of view, maintenance of the operation section and the air intake section can be performed. Can be done easily.
