JP2830060B2 - Air intake section mounting structure for bubble generating bathtub - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a structure for mounting an air intake section of a bubble generating bathtub.

(B) Conventional technology Conventionally, as described in Japanese Patent Application Laid-Open No. Sho 59-135058, a bubble-generating bathtub sucks bathwater between a bathtub main body and a circulation pump installed outside the main body. A hot water circulation channel consisting of a pipe and a hot water supply pipe is provided, an air intake is provided in the middle of the hot water supply pipe, and the hot water is supplied through the hot water circulation channel by the operation of a circulation pump. Is jetted from a nozzle into a bathtub main body, and at the same time, air sucked from an air intake section is mixed to perform jetting of hot water mixed with air bubbles.

(C) Problems to be Solved by the Invention As described above, in the bubble generating bath, an air intake portion is always required, and the air intake portion is opened at a predetermined location so that air can be sucked. The structure in which the intake section is attached to the edge of the bathtub body, from the viewpoint of effective use of the space around the bathtub, ensures that the bath water does not enter the installation section and flow out of the bathtub body. Otherwise, the bath water may flow into the embedded wall around the bath tub, causing decay or damaging the bathroom wall.

Furthermore, if the edge of the intake case for air intake is attached to the mounting hole of the bathtub body so as to be overlapped, the edge is made thicker by interposing a seal member between them, thereby ensuring the strength with strength. With such a structure, if the operation panel section is provided on this air suction section, the height of the operation panel section as a whole increases,
Furthermore, it becomes difficult for the edge to reduce the width,
A high convex portion was formed at the edge of the bathtub body, which was disadvantageous in terms of design and handling.

(D) Means for Solving the Problems According to the present invention, a bath water circulation flow path comprising a bath water suction pipe and a bath water high-pressure pipe is provided between a bathtub body and a circulation pump installed outside the bathtub body. The end of the bath water strong feeding pipe is opened to the inside of the bathtub body as a plurality of jet nozzles, and the air intake part is connected to the same bath hot water feeding pipe,
In the bubble generating bath tub configured so that the bath water mixed with bubbles can be jetted into the bathtub main body from the jet nozzle, a flange portion is formed on an upper edge portion of an intake case constituting an air intake portion, and the flange portion is formed on the bathtub main body. By placing the suction case vertically below the mounting hole by placing it on the peripheral edge of the mounting hole drilled in the edge, and furthermore, the suction case of the suction case in which the peripheral edge is bordered by a thin frame of metal sheet. The flange portion and the edge of the bathtub body are fastened and fixed with a penetration bolt via a sealing member, the air intake portion is fixed to the bathtub body, and the operation panel portion is further mounted above and mounted thereon. It is an object of the present invention to provide a structure for mounting an air intake portion of a bubble generating bathtub.

(E) Function / Effect According to the present invention, when the air intake portion is mounted on the bathtub body, a mounting hole is formed at a required portion on the edge of the bathtub body, and the air intake portion is formed from above the mounting hole. The suction case is inserted, and the flange formed on the upper edge of the suction case is placed on the peripheral edge of the mounting hole, so that the suction case is suspended from the edge of the bathtub body. In addition to being concealed on the outside of the case, it can be pulled out from the mounting hole when necessary for maintenance etc., and can be taken out.Furthermore, when fixing the intake case, especially at the flange of the intake case, The edge frame of the metal sheet is framed, and a seal member is interposed between the flange portion and the edge portion of the bathtub body, and the flange portion of the intake case, the edge portion of the bathtub body, the seal member, By overlapping the edge frame and tightening and fixing with insertion bolts The air intake section is fixed to the bathtub body, and therefore, the suction case can be completely fixed to the mounting hole in a sealed state. Deformation can be prevented, and the mounting work can be easily performed.

Furthermore, since the edge frame borders the edge of the intake case with a thin metal plate, the flange can be made as thin as possible, the width of the flange can be shortened, and the strength can be sufficiently secured. The mounting structure can be made into a thin walled, narrow and compact structure, so that the operation panel to be mounted on top of it can be made lower by that amount, the edge of the bathtub body can be simplified, and the protruding part can be reduced as much as possible. It has the effect that it can be configured so as not to cause any trouble by using it at a low level.
