Description

[Detailed description of the invention] The present invention relates to a bubble bath in which bubbles are blown out by discharging air into the bathtub from the side wall of the bathtub together with hot water, especially the structure of the part that sucks the air.
A water suction pipe 8 and a water discharge pipe 9 are attached to the side wall of the bathtub 13, and an air suction pipe 1 is connected to the water discharge pipe 9. Hot water in the bathtub 13 is sucked through the water suction pipe 8, and the hot water is discharged together with the air introduced from the air suction pipe 1. In a foam bath in which bubbles are spouted by discharging bubbles from a water discharge pipe 9 into a bathtub 13, a groove 2 is provided all around the outer circumference of the upper end of a cylindrical air suction pipe 1 whose upper end surface is open. death,
A male threaded portion 3 is formed on the outer periphery of the air suction pipe 1 above the groove 2, and a vertical air circulation groove 4 is formed in the male threaded portion 3 and opens to the upper end of the air suction pipe 1 and the groove 2. A gasket 6 having a vertical thickness smaller than the vertical width of the groove 2 is attached to the lower part of the inner periphery of the cap body 5 with an opening on the bottom surface, and a gasket 6 is attached to the inner circumference of the cap body 5 above the gasket 6. A foam bath comprising a female threaded part 7, a cap body 5 attached to the upper end of the air suction pipe 1 by screwing the female threaded part 7 into the male threaded part 3, and a packing 6 fitted into the groove 2. It is.

Hot water in the bathtub is sucked in by a pump, and when the hot water is discharged into the bathtub, air is introduced from the air suction port using the principle of a jet pump, and the air is discharged into the bathtub at the same time as the hot water, thereby removing bubbles from inside the bathtub. For bubble baths designed to emit hot water, sometimes the air inlet is closed and only hot water is ejected. In such cases, conventionally the air intake port was blocked with a set screw, but if the set screw is removed to open the air intake port, there is a risk of losing the set screw, and the set screw may be tightened too tightly. Now I had a problem where I couldn't remove the set screw.

The present invention was developed in view of the above points, and the opening of the air suction pipe can be opened and closed freely by the cap body, and there is no possibility that the cap body may come off or the cap body may be tightened too tightly. The purpose is to provide a bubble bath that is free from fear.

The present invention will be explained in detail below with reference to Examples. Bathtub 13
As shown in FIG. 1, a water suction pipe 8 and a water discharge pipe 9 are attached to the side wall of the bathtub 1 so as to open into the bathtub 1, and the water suction and water discharge pipes 8 and 9 are connected to a pump 10. An air pipe 11 is connected to the water discharge pipe 9, and an air suction pipe 1 is attached to the tip of the air pipe 11 at the flange 12 of the bathtub 1, the top and bottom being open and the opening at the top being formed as an air suction port. . 14 in Figure 1 is the pump 10
This is the operation switch. A recessed groove 2 is recessed around the entire circumference of the upper end of the air suction pipe 1, and a male threaded portion 3 is formed on the outer periphery of the air suction pipe 1 above the recessed groove 2 as shown in FIG. It has been formed. In addition, a plurality of air circulation grooves 4 which open to the upper end of the air suction pipe 1 and the groove 2 are recessed in the male threaded portion 3 in the vertical direction. As shown in FIG. 3, the cap body 5 is formed with an opening on the lower surface, and a groove 15 is fitted into the inner periphery of the lower end of the cap body 5 over the entire circumference, and a ring-shaped packing 6 is fitted into the groove. It is installed by fitting it into 15. The vertical thickness of this packing 6 is smaller than the vertical width of the groove 2.

Therefore, when attaching the cap body 5 to the air suction pipe 1, first place the cap body 5 over the upper end of the air suction pipe 1 and press the cap body 5 downward. It climbs over and fits into the groove 2. In this state, when the cap body 5 is turned and the female thread part 7 of the cap body 5 is screwed into the male thread part 3 of the air suction pipe 1, and the cap body 5 is further tightened, the gasket 6 is attached to the bottom surface of the groove 2 as shown in FIG. 4a. Press the entire circumference. Due to the pressure contact of the gasket 6 to the lower surface of the concave groove 2, the cap body 5 is no longer tightened, and the cap body 5 is no longer strongly tightened.
When the cap body 5 is tightened as shown in FIG. 4a, the pressure contact between the lower surface of the groove 2 and the packing 6 completely blocks air communication between the inside and outside of the air suction pipe 1, and no air is introduced. The hot water sucked in by the water suction pipe 8 is discharged as it is from the water discharge pipe 9.

Next, when the cap body 5 is turned in the direction of loosening, the gasket 6 hits the upper surface of the groove 2 as shown in Fig. 4b, and the cap body 5 cannot be turned any further, and the cap body 5 is air-filled. It will not come off from the suction pipe 1. When the cap body 5 is loosened as shown in FIG. When hot water is sucked in and discharged from the discharge pipe 9 into the bathtub 13, outside air is introduced from the air suction pipe 1 through the air pipe 11 into the water discharge pipe 9 using the principle of a jet pump, thereby eliminating bubbles. It can be ejected into the bathtub 13. If you want to remove the cap body 5 from the air suction pipe 1, turn the cap body 5 even more forcefully than in this state, and the gasket 6 will go over the male threaded part 3.
This is easy to do, and the cap body 5 can be removed for cleaning without the need for any tools.

As mentioned above, according to the present invention, it is possible to introduce and shut off air to the air suction pipe simply by tightening or loosening the cap body. Therefore, there is no risk that the cap body will become too tight and cannot be removed, or that it will become too loose and accidentally come off.
