DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application This invention relates to an air intake chamber structure in an air intake section of a bubble-generating bathtub.

(B) Conventional technology Conventionally, as described in Japanese Patent Application Laid-Open No. 59-135058, a bubble-generating bathtub has a bath water suction system between the bathtub body and a circulation pump installed outside the bathtub body. A bath water circulation channel consisting of a pipe and a forced bath water supply pipe is provided, and an air intake part is provided in the middle of the forced bath water supply pipe, and the bath water is circulated through the bath water circulation channel by the operation of a circulation pump. Some bathtubs are designed to eject water from a nozzle into the bathtub body, and simultaneously mix it with air sucked in from an air intake to eject bathwater mixed with bubbles.

(c) Problems to be Solved by the Invention As described above, the bubble-generating bathtub requires an air intake part, but the air intake part is connected to the intake pipes leading to various jet nozzles. If the jet nozzle is composed of a large number of jet nozzles, for example, on the foot side, dorsal side, ventral side, etc., a corresponding number of intake pipes are connected to the air intake part, so the air intake part The intake pipes extending from the lower end of the pipe intersect in a complicated manner, making piping construction complicated by having to take detours to prevent the pipes from intersecting.

(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 provided between a bathtub body and a circulation pump installed outside the bathtub body. A plurality of terminal ends of the bath water bullet delivery pipe are opened into the bathtub body to serve as jet nozzles, and an air intake part is connected to the bath water bullet delivery pipe so that air bubbles are mixed from the jet nozzle. In a bubble-generating bathtub configured to be able to spray bath water into the bathtub body, the air intake section is divided into a plurality of independent intake chambers by a longitudinal partition wall, and an intake pipe is connected to the lower end of each intake chamber. The air intake part of the bubble-generating bathtub is formed by communicating various jet nozzles with different jetting positions with each suction chamber via the same suction pipe, and at least one of the suction chambers having a lower end extending from the other suction chambers. The purpose of the present invention is to provide an intake chamber structure.

(e) Function/Effect In this invention, when taking a bath in a bubble-generating bathtub, the circulation pump is activated by operating the operation panel provided on the edge of the bathtub body, and the bathwater is supplied through the bathwater circulation channel. This system circulates air through the air intake and generates a jet of bubbles to provide a bubble bath.In particular, as the bath water circulates by operating the operation panel, air is taken in through the air intake to create a jet of bubbles. is carried out to activate the bubble-generating bath water jet.

A large number of intake pipes are connected to each intake pipe of the air intake section, and the pipes are communicated with various jetting nozzles, so that the air taken in from the air intake section is jetted out in the form of bubbles from the various nozzles. In such a configuration, one of the intake chambers has a lower end extending further than the other intake chambers, so that at least a portion of the intake pipe communicating with the lower end of the intake chamber is lower than the other intake pipes. The intake pipes surrounding the bathtub body can be set up and down on the same plane without overlapping, thus minimizing the internal dimensions of the bathtub. There is no need to take up extra space for piping, the piping can be centralized, the piping is compact, and piping construction is easier.

In addition, on the outside of the switch case (17), the same case (
An outer case (19) is provided to surround the outer case (■9), and there is a certain distance (S) between the periphery of the outer case (■9) and the switch case (17) inside thereof. is held, and the peripheral edge of the outer case (19) is configured to fit with the upper edge of an air intake case (20) of the air intake section (5), which will be described later.
19) An intake hole (40) for taking air into the air intake part (5) is provided on the back side.

Next, the air intake section (5) will be explained.

The air intake section (5) is mainly composed of an intake case (20) formed in a substantially rectangular box shape. That is,
The intake case (20) is open at the top and has an air exhaust hole at the bottom to form an air flow path (L) inside, and the upper edge of the intake case (20) is folded outward to form a flange. (2

) (24”) (25°°), and each of the sound-absorbing pipes (28) and (29) extends downward so that the lower ends are located halfway between the upper and lower chambers. There is.

In other words, each of the muffling pipes (28) (2B) is interposed in the middle of the airflow passage (L), and the upper muffling pipe (28) and the lower muffling pipe (29) are naturally connected to each intake chamber (23). ) (24) It is formed to have a smaller diameter than (25), so the noise emitted from each muffling pipe (28) (29) flows into the large volume intake chamber (23) (24) (25) and becomes a sound wave. They resonate, interfere with each other, and cancel each other out to perform the silencing function.

In this embodiment, each intake chamber is divided into upper and lower chambers, and upper and lower noise reduction pipes (2g) (29) are provided in each of the upper and lower chambers. Even a single silencing pipe can perform the silencing function.

Furthermore, first intake chambers (23) on both sides of the intake case (20)
) and the third intake chamber (25) are provided with first and third air exhaust holes (30) (31) facing outward, and a second intake chamber (31) is provided in the middle lower part of the intake case.

10-2) In the actual piping of (10-3), the ventral intake pipe (10-1) is connected to ventral jet nozzles (4) (4) disposed on the left and right sides of the bathtub body (1). Two intake pipes (1) are installed around the bathtub body (1) to communicate with each
0-3) The piping is set so as to surround it with (10-3).

Therefore, the ventral intake pipe (10-3) (to-3) is connected to the left and right air exhaust holes (32) (33) at the lower end of the second intake chamber (24), respectively, so that the ventral intake pipe (10-3) The intake pipe (10-3) (10-3) will be installed at a lower position than the other dorsal and foot intake pipes (10-1) (to-2), so they will not be on the same plane. This makes it easier to set up the pipes, and since each pipe is set in the upper and lower positions, the space below the edge of the bathtub, which is normally reserved for pipes, can be made as narrow as possible.
Therefore, the internal dimensions of the bathtub body can be increased, and the bathing space can be made as wide as possible within the limited overall size of the bathtub.In this way, the piping itself has a centralized piping structure. The compact piping space makes piping construction work easier.
