Description

[Detailed description of the invention] (b) Industrial application field The present invention relates to piping in 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 Many of the bath water pipes, intake pipes, etc. are made of steel pipes, which increases the weight and cost, and the flow velocity is 1.5.
If the flow velocity exceeds m/s, the inner circumferential surface of the steel pipe will wear out as it exceeds the flow velocity range in which the steel pipe is used, making it difficult to use it in bubble-generating bathtubs.

In addition, many synthetic resin products have inferior heat resistance, chemical resistance, and moldability, and especially in cases where high-temperature bath water is forced to circulate or are equipped with a reheating function, the heat and jet flow Due to the strength of the pressure, there was a risk that the pipe would be damaged, and this had the disadvantage that it could not withstand long-term use.

(d) Means for Solving the Problems In this 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 ends of the forced bath water supply pipe are opened into the bathtub body to form a spout nozzle, and an air intake part is connected to the forced bath water pipe so that air bubbles are mixed from the spout nozzle. In the bubble-generating bathtub, which is configured to be able to squirt bathwater into the bathtub body, pipes such as the bathwater suction pipe, forced bathwater supply pipe, and intake pipe are made of thermoplastic material with excellent heat resistance, chemical resistance, moldability, etc. It is an object of the present invention to provide piping for a bubble-generating bathtub, which is made of resin and has different materials depending on the location where it is used.

(E) Function/Effect In this invention, when taking a bath in a bubble-generating bathtub, bathing is performed by operating an operation panel provided at the edge of the bathtub body to obtain a jet of bubbles. In particular, by operating the operation panel section, air is taken in from the air intake section, and the bubble-generating bath water jet is activated.

For example, if thermoplastic resin belonging to polyolefins, polyamide resin, etc. or thermoplastic resin with excellent heat resistance, chemical resistance, moldability, etc. It can withstand water and heat for a sufficiently long period of time, has good moldability, and is flexible, so it can absorb the shock that occurs when piping is hit during construction, preventing damage. It can also be prevented,
In addition, because of this material, blow molding is possible, and when providing a bellows for impact mitigation in the middle, it is easy to form an integrally molded bellows, and it is also possible to form a bellows in a complex pipe surrounding the bathtub body. The structure also has the effect of being easily molded,
On the other hand, if the intake pipe is made of thermoplastic resin belonging to polyolefin or polybutene resin, it will be easier to repair the pipe by heat welding on site. With glass (nylon 6) and without glass nylon 11
), the hard part and flexible part can be molded separately, so use the hard tip part for the part that attaches to the bathtub side wall. Since a flexible part can be used for the main body, even if there is a shock during construction, it will not put an unreasonable load on the bathtub side wall, and the construction can be carried out on site without damaging the bathtub. By using different materials depending on where the pipe is used, it is possible to achieve the most beneficial function depending on the purpose and situation.

Then, by pressing the operation display section 12-1 with a finger, the switch mechanism 16 below it is operated 0N10FF to perform a desired driving operation.

Further, as shown in FIG. 4, a molded portion 16° is provided vertically at the side end of the operation display portion 12-1.
゛ is cased together with the push switch mechanism 16 by the switch case 17, and the molded part 16°
A lead wire 18 is led out from the lead wire 18, and a connector 16-1 is interposed in the middle of the lead wire 18 to connect it to the control section C. 16-2 is a protective case.

Further, an outer case 19 is provided on the outside of the switch case 17 in a state that surrounds the case 17 as shown in FIG. A fixed interval S is provided between the two.

Moreover, the peripheral edge of the outer case 19 is configured to fit into the upper edge of the air intake case 20 of the air intake section 5, which will be described later.

Furthermore, an air intake hole 40 is provided on the back surface of the outer case 20 for introducing the air into the air intake section 5.

The intake case 20 of the air intake section 5 is open upward, has an air discharge hole in its lower part, and has an air flow passage formed therein.The upper edge of the intake case 20 has a
A flange portion 21 is provided by folding the edge portion outward, and the upper portion of the flange portion 21 is in an open state.

Further, the air flow path inside the intake case 20 is partitioned into three independent chambers by a vertical partition wall 22, and each chamber is designated as a 1st, 2, and 3rd intake chamber 23, 24, and 25.

Each intake chamber 23, 24, 25 serves as such an air flow path.
functions as a cylindrical air suction part, and the upper opening periphery thereof is formed into a substantially tapered shape.
In this embodiment, this air suction part is constructed as a sound-muffling pipe, and the sound-muffling pipe is formed into a cylindrical air suction part 28, 29, and this upper end opening peripheral edge part 28'.

29゛ is formed into a substantially tapered shape.

That is, in the upper part of each intake chamber 23, 24.25, a first partition plate 26 and an upper partition plate 27 are provided horizontally with a constant interval between them. An upper air suction part 28 and a lower air suction part 2 each have a cylindrical shape.
9 is installed vertically, and the upper and lower sides are communicated via the suction portions 28 and 29.

In addition, each intake chamber 23 , 24 , 25 has an upper partition 26
and the upper partition plate 27, the upper chambers 23', 24', 25
″ and lower chamber 23″.

It is divided into 24° and 25°.

Furthermore, the upper air suction part 28 allows the air intake case 20 to

and the lower chambers 23°°124" and 25°" are in communication.

Moreover, each cylindrical air suction part 28, 29 extends downwardly, and its lower end is located halfway between each upper and lower chamber.

In other words, each of the cylindrical air suction parts 28 and 29 is interposed in the middle of the air flow path, and the cylindrical upper air suction part 28 and lower air suction part 29 are naturally connected to each other. It is formed to have a smaller diameter than the air chambers 23, 24, and 25.

Therefore, the noise emitted from each of the air suction sections 2B and 29 flows into and diffuses into each of the large-capacity intake chambers 23, 24, and 25, thereby reducing acoustic energy and performing a silencing function.

In this way, each of the air suction parts 28, 29 is configured to function as an upper and lower sound deadening pipe, and therefore, the air flowing into the air suction parts 28, 29 is smoothly flowed by the tapered portion of the upper end opening. The air inlet 2, which functions as a muffling pipe, reduces the noise caused by the inflow of air and reduces the noise accordingly, and eliminates the noise when air is taken in from the intake hole 40 of the air intake part 5.
I am trying to delete it by 8.29.

Furthermore, first intake chambers 23 on both sides of the intake case 200,
First and third air exhaust holes 30 and 31 are provided at the lower end of the third intake chamber 25 toward the outside.

is extended to a position below the first and third air exhaust holes 23.25, and left and right air exhaust holes 3 are provided on both sides of the lower end thereof.
2.33 is provided.

Therefore, in the vertical positional relationship between the first and third air exhaust holes 30.31 and the left and right air exhaust holes 32.33, the latter is located lower than the former.

This is configured so that the intake pipes 10 communicating with each air exhaust hole are not located on the same plane, but are located one above the other so that they do not overlap.

That is, the first and second air exhaust holes 30.31 have the first
As shown in the figure and Fig. 6, the foot side and dorsal side intake pipe 1
0-1.10-2 are connected, and the same intake pipe 10
-1.10-2 is configured to communicate with the foot-side and dorsal-side jet nozzles 2.3, respectively, and to suck in and supply air using an ejection function that creates a negative pressure by a jet of bath water.

Further, the left and right air discharge holes 32.33 are connected to abdominal intake pipes 10-3 that are piped on both sides of the bathtub body 1, and the intake pipes 10-3 are connected to abdominal jet nozzles 4.4.
The nozzle 4.4 communicates with the nozzle 4.4 and uses an ejection function to draw in and supply air.

In addition, 20 degrees is a mold part case which accommodates the mold part 16', 34 is a seal, 16-1 is a connector, and 16-2 is a protective case.

In the bubble-generating bathtub A as described above, the gist of the present invention is to provide heat-resistant, chemical-resistant pipes such as the bath water suction pipe 7, the forced bath water supply pipe 8, and each of the suction pipes 10-1, 2, 3, etc. sex,
It is constructed from a thermoplastic resin with excellent moldability, and the material is varied depending on the location where it is used, so that economical piping with strength can be achieved.

That is, for the forced bath water pipe 8, a thermoplastic resin having excellent heat resistance, chemical resistance, and moldability, such as a thermoplastic resin belonging to polyolefin, polyamide resin, or polybdenum resin, is used.

This material is lighter in weight and lower in cost than conventional copper pipes, and can withstand wear on the inner circumferential surface due to the high flow rate of hot water from the V8m pump P. If a firing function is added, high-temperature hot water must be sent, and a thermoplastic resin with sufficient heat resistance will be used.

Therefore, it can sufficiently absorb the jet pressure and heat of bath water, and has good moldability. However, damage can be prevented, and because of the material, blow molding is also possible, and when providing a bellows part for impact mitigation in the middle, it is easy to perform integral molding by blow molding. have

In addition, in the intake pipes, the dorsal intake pipe 10-L, the foot intake pipe 10-2, and the ventral intake pipe 10-3 are made of thermoplastic resin or polypden resin belonging to polyolefin, and are manufactured to reduce weight. This makes it easy to repair the pipes on-site, especially since the intake pipe only has an air feeding function.
Thermoplastic resin is used because it is lighter in weight than the strength of the material itself, making piping and repair work easier.

The bath water suction pipe 7 is made of thermoplastic polyamide resin and has a glass-containing part 7-1 (nylon 6) and a glass-free part 7-.
2 (Nylon 11). Conventionally, bath water supply pipes were made of cast bronze and steel pipes, so when the bathtub body was brought into the bathroom, the bath water supply pipe was If a shock is applied to the pipe, there is a risk that the artificial marble or the like on the side wall of the bathtub, to which the tip of the pipe is attached, will receive the load applied to the pipe and be damaged. The main tube part is made of a flexible thermoplastic polyamide resin (nylon 11), and the tip part, which is the part that attaches to the side wall of the bathtub, is made of glass-filled polyamide resin 7-1 (nylon 6). The mounting part is hard, and the main pipe part is soft, absorbing shock even if it is applied to the main pipe, making it easy to handle on-site, and easy to mold.

In this way, each pipe is made of a different material depending on where it is used, and because it is based on thermoplastic resin, it is possible to use the most suitable resin depending on the specificity of the place where it is used, reducing costs. This allows for a piping structure that is both inexpensive and strong.
