Abstract

PURPOSE:To prevent hot water for bathing, which flows reversely, from flowing into a sucking pipe and to easily make the hot water for bathing flow out by forming the sucking pipe, which is interposed between an air lead-in part and respective jetting nozzles, to be almost mountain-shaped and providing the sucking pipe to be inclined downward toward the direction of the jetting nozzle. CONSTITUTION:A back side sucking pipe 10-1 from an air lead-in part 5 to a back side jetting nozzle 3 is formed along the outside surface of a main body 1 of a bathtub and the middle part of the sucking pipe 10-1 is bent in an inner direction. The back side sucking pipe 10-1 is inclined in the shape of slight ascending gradient rather than the air lead-in part 5 and further inclined in the shape of descending gradient toward the jetting nozzle 3 rather than the middle part. Thus, the hot water for bathing from the back side jetting nozzle 3 is prevented from flowing into the back side sucking pipe 10-1 and the reversely flowing hot water for bathing can be easily exhausted.

Description

[Detailed description of the invention] (b) Industrial application field The present invention relates to an air intake pipe 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 Japanese Patent No. 35058, a bath water suction vibe and a bath water supply pipe are connected between the bathtub body and the circulation pump, and an air intake part is provided in the middle of the pipe.

With this structure, the VFI ring pump sucks the bath water in the bathtub body through the bath water suction vibrator, and at the same time, the water is jetted from the pump into the bathtub body through the bath water supply pipe.

At this time, the air intake part mixes the bath water into the bath water by using the negative pressure generated by the jet of bath water from the air intake part. I'm trying to make it squirt out.

Further, the air intake section is formed by opening the air intake section at the edge of the bathtub body, for example, and an intake pipe is interposed between the air intake section and the jet nozzle.

Furthermore, the intake pipe is disposed substantially horizontally along the bath water forced delivery pipe, and is configured to smoothly send air to the bath water forced delivery pipe in the vicinity of the jet nozzle.

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

In other words, when the bath water jet is not performed, the bath water in the bath water bullet delivery pipe flows back into the intake pipe and easily remains in the pipe, or the bath water flows from the jet nozzle into the intake pipe. Therefore, there was a risk that the bath water would accumulate in the intake pipe, emitting an odor from the bath water, or staining the inside of the pipe with the remaining bath water.

An object of the present invention is to provide an intake pipe 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 pipe and a bath water forced delivery pipe is interposed between the bathtub body and the circulation pump. The end of the forced-feeding pipe is opened into the bathtub body to form a spouting nozzle, and an air intake part is connected to the bathwater circulation flow path so that bubble-mixed bathwater can be spouted from the nozzle into the bathtub body. In the configured bubble generating bathtub, the air intake part and each jet nozzle are communicated via an intake pipe,
The present invention provides an intake pipe structure for a bubble-generating bathtub, characterized in that the midway of the intake pipe is formed into a substantially mountain shape, and a downwardly extending filler portion is provided toward a jet nozzle.

(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 air intake part functions as an ejector. By mixing the air sucked into the bath water through the suction pipe, 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 function of purifying your body and maintaining your health due to the ultrasonic action generated by the air bubbles.

In particular, in the present invention, the intake pipes interposed between the air intake section and each jet nozzle are formed into a substantially mountain shape, and because the pipes are inclined downward toward the jet nozzles, reverse flow from the same nozzles can occur. The bath water can be prevented from flowing into the intake pipe, and even if the bath water flows backward, it can be easily drained out.

Therefore, no bath water remains in the intake pipe, and the water can be completely drained, which has the effect of solving problems such as strange odors from the remaining hot water.
