Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Field of the Invention The present invention relates to an air intake section structure 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 is provided between a bathtub main body and a circulating pipe installed outside the main body. A hot-water circulation channel consisting of a pipe and a hot-water bath is provided, and an air intake section is provided in the middle of the hot-water pipe. 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, the bubble generating bath requires an air intake section, and when various ejection nozzles having different ejection positions communicate with the air intake section, for example, the back side ejection is performed. If the back side nozzle is closed when the nozzle, foot side nozzle, and ventral side nozzle are connected to the air intake, there is a risk that the bath water will flow backward instantaneously and back into the air intake. In this case, in this case, the bath water that has flowed backward flows into the other connected ejection nozzle side to generate an abnormal bath water flow pressure, and it is not possible to obtain a desired desired jet pressure or jet form by controlling in advance. There is a fear.

(D) Means for Solving the Problems In the present invention, a bath water circulation flow path composed of a bath water suction pipe and a bathtub forced feeding pipe is provided between a bathtub body and a circulation pump installed outside the bathtub body. A plurality of bath water high-pressure pipes are opened at the ends of a plurality of bath hot water pipes into the bathtub main body to form a jet nozzle, and an air intake section is connected to the high pressure bath pipe to communicate with an air intake section. In a bubble generating bathtub configured to allow hot water to be injected into the bathtub main body, the inside of the air intake section is divided into a plurality of independent intake chambers by vertical partition walls, and each chamber and various ejection nozzles having different ejection positions. Are communicated with each other, thereby providing a space between the various ejection nozzles via the air intake unit.

(E) Function / Effect In the present invention, when bathing in the bubble generating bathtub, the operation panel provided on the edge of the bathtub body is operated to operate the circulation pump, and the bath is circulated through the bathtub circulation flow path. The hot water is circulated and the air is taken in from the air intake section to obtain a bubble jet to perform bathing in the bubble bath water. In particular, by operating the operation panel section, air is taken in from the air intake section as the bath water circulates. Is performed to operate the bubble-generating bath hot water jet.

At this time, the inside of the air intake section is divided into a plurality of independent chambers by the vertical partition walls, so that air flows into the various ejection nozzles from the independent chambers, and accordingly, For example, when one of the ejection nozzles is closed, even if the bath water flows backward and flows into the air intake section, it is an independent chamber, so that the back-flow bath water does not flow into the chamber circulating with the other ejection nozzle. As a result, the backflow of the bath water between the various ejection nozzles is prevented, the ejection nozzles are accurately controlled, and the operation of changing the jet flow form can be reliably performed.
