DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jet bath air intake piping structure.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 3, a jet bath which is used by jetting a jet water flow into a bathtub 1 when bathing is used. Generally, in a jet bath, a water absorption pipe (not shown) that opens into the bathtub 1 and a jet water flow pipe 8 are connected to a pump 6, and the pump 6 sucks the water in the bathtub 1 from the water absorption pipe.
This water is made into a jet water flow and jetted out into the bathtub 1 from the jet water flow pipe 8. An air intake pipe section 9 for supplying air to the jet water flow pipe 8 in order to mix air bubbles in the jet water flow in front of the jet injection port 7 into the bathtub 1.
Is connected to one end of the air intake piping 9
The other end of is connected to a trap tube 5 having an air inlet 4 on the upper surface of the flange 2 of the bath 1. The air intake pipe section 9 includes a straight pipe 91 and the straight pipe 91.
And an elbow joint pipe 92 that connects them at a right angle.

[0003]

By the way, there are generally various sizes of bathtubs 1 used as jet baths. Conventionally, when the sizes of the bathtubs 1 are different from each other as described above, the positional relationship between the pump 6 and the jet injection port 7 is made constant so that the jet water flow pipe 8
However, in the air intake pipe section 9, the position of the air intake port 4 (trap 5) differs depending on the size of each bathtub 1, and accordingly the jet water flow pipe 8 and the air intake port 4 (trap 5) will change, so
It was necessary to design the length of piping according to the size of the.

As a method of designing the length of the air intake piping portion 9, for example, the air intake piping portion 9 is designed.
Various sizes are prepared in advance for the straight pipes 91 constituting the above, and a size corresponding to each bathtub 1 is selected at the time of construction, or the straight pipes 91 are cut to have a size corresponding to each bathtub 1. There is a method of adding or replenishing it, but the former is inefficient because it is necessary to prepare a large number of stocks of various sizes as the straight pipe 91, while the latter requires labor for processing the straight pipe 91. There was a flaw.

The present invention has been made in view of the above circumstances, and provides an air intake piping structure for a jet bath that can be installed correspondingly even when the sizes of bathtubs are different.

[0006]

An air intake piping structure for a jet bath according to a first aspect of the present invention comprises an air intake piping section composed of a straight pipe and an elbow joint pipe connecting the straight pipes at right angles to each other. In the air intake pipe structure of the jet bath in which air is supplied to the jet water flow pipe that ejects the jet water flow into the bathtub by the air intake pipe portion, the straight pipe is stretchable.

A jet bath air intake piping structure according to a second aspect of the present invention is the jet bath air intake piping structure according to the first aspect, in which a straight pipe is inserted into and removed from the outer pipe and the outer pipe. It is characterized by being composed of a pipe.

In the jet-bath air intake piping structure according to a third aspect, in the jet-bath air-intake piping structure according to the first aspect, the straight pipe is provided with a flexible bellows portion which is expandable and contractible. It is characterized by.

[0009]

According to the air intake piping structure of the jet bath according to the first aspect, the length of the piping of the air intake piping can be freely changed by expanding and contracting the straight pipe. Therefore, even if the positional relationship between the air intake port and the jet water flow pipe is different due to the difference in the size of the bathtub of the jet bath, it is easy to replace the straight pipe, cut or refill, etc. Can be plumbed.

According to the jet-bath air intake piping structure of the second aspect, in the jet-bath air-intake piping structure of the first aspect, the straight pipe extends from the outer pipe in a removable manner from the outer pipe. Since it is composed of the inner pipe, the straight pipe expands and contracts by inserting and removing the inner pipe with respect to the outer pipe, and the length of the pipe of the air intake pipe portion can be freely changed.

According to the jet-bath air intake piping structure of a third aspect, in the jet-bath air intake piping structure of the first aspect, the straight pipe is provided with a flexible bellows portion capable of expanding and contracting. So, by expanding and contracting this bellows, the straight tube expands and contracts,
It is possible to freely change the length of the air intake piping. Moreover, since the bellows portion of the straight pipe has flexibility, flexibility is imparted to the entire pipe,
Even if the pipe is twisted a little, it can be connected easily.

An air intake pipe section 3 configured by combining and connecting with 2 is provided, and by this air intake pipe section 3,
In the air intake piping structure of the jet bath in which the air intake port 4 provided in the bathtub 1 and the jet water flow pipe 8 for ejecting the jet water flow into the bathtub 1 are connected to each other, the straight pipe 31 can be expanded and contracted. It is what

The embodiment will be described in detail below. A flange 2 is formed on the outer periphery of the upper end of the bath 1. At one corner of the flange 2, a trap 5 having an air suction port 4 penetrating the flange 2 vertically and opening upward is provided. The trap 5 has a silencer, a dust filter, and the like built therein.

On the other hand, a pump 6 which is a power source for producing a jet water flow is attached to the outer surface of the side wall of the bathtub 1 adjacent to the corner portion where the air intake port 4 is opened.
A water absorption pipe (not shown) and a jet water flow pipe 8 which communicate with each other and open in the bathtub 1 are connected to the pump 6, and the pump 6 sucks water from the bathtub 1 through the water absorption pipe, This water is jetted as a jet water stream from a jet injection port 7 opening in the bathtub 1 through a jet water flow pipe 8. The jet injection ports 7 are provided at two places on the left and right above the pump 6 on the side wall of the bathtub 1, and the jet water flow pipe 8 is branched into two pipes on the way, and the jet injection ports 7 and 7 are provided on the left and right sides, respectively. It is connected to the.

The trap 5 having the air suction port 4 and the jet water flow pipe 8 are connected to each other by an air intake pipe section 3. That is, one end of the air intake pipe part 3 is connected to the jet water flow pipe 8 in front of the jet injection port 7 into the bathtub 1, and the other end of the air intake pipe part 3 is connected to the trap 5. . When the jet stream flows through the jet stream pipe 8,
Like the ejector, air is taken into the jet water flow from the air intake pipe 3 and formed into bubbles to be ejected into the bathtub 1 together with the jet water flow.

The air intake pipe section 3 is constructed by combining a straight pipe 31 and an elbow joint pipe 32 and connecting them together. In this embodiment, two straight pipes 31 and two elbow joint pipes 32 are used.

Explaining the arrangement of the straight pipe 31 and the elbow joint pipe 32, a branch portion is provided horizontally from the jet water flow pipe 8 before the jet injection port 7, and one elbow joint is provided at this branch portion. Pipe 32
Is connected. The other end of the elbow joint pipe 32 is opened upward, and one end of one straight pipe 31 is fitted into and connected to this, so that the straight pipe 31 is plumbed vertically upward. The other elbow joint pipe 32 is fitted to the upper end of the straight pipe 31, and the other end of the elbow joint pipe 32 is opened in the horizontal direction toward the trap 5, and one end of the other straight pipe 31 is attached to this. Is inserted and connected to horizontally pipe the straight pipe 31, and the other end of the straight pipe 31 is connected to the trap 5.

In this embodiment, the straight tube 31 is shown in FIG.
As shown in (b), it is composed of an outer pipe 34 and an inner pipe 35 that extends from the outer pipe 34 in a removable manner.
