Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathtub arm grip, and more particularly to a bathtub arm grip having a bubble injection function and used in a bubble bathtub.

0002

BACKGROUND OF THE INVENTION As is well known, a bubble bathtub is a bathtub constructed so that water containing bubbles is sprayed into the bathtub.

[0003] Many bubble bathtubs are constructed so that hot water in the bathtub is supplied by a pump to a bubble injection nozzle, and air is sucked in by the bubble injection nozzle to inject bubble-containing water into the bathtub. This bubble injection nozzle is provided on the bottom of the side wall of the bathtub.

[0004] Instead of sucking air into the bubble injection nozzle, air may be mixed with hot water using a line mixer or the like upstream of the bubble injection nozzle.

[0005]

[Problems to be Solved by the Invention] In order to obtain a uniform bubble massage effect over the whole body, it is preferable to install bubble injection nozzles in as many places as possible. From the viewpoint of waterproofness, it is preferable to install as few bubble injection nozzles as possible.

The present invention has been made in order to satisfy these contradictory demands.

[0007]

[Means for Solving the Problems] The arm grip for a bathtub according to claim 1 is an arm grip for a bathtub attached to a bathtub, which includes a jetting port for water containing bubbles, and a water jetting port connected to the jetting port so as to allow water to flow therethrough. It is characterized by comprising an inlet.

[0008] The arm grip for a bathtub according to a second aspect of the present invention is the arm grip for a bathtub according to the first aspect, further comprising an air suction port that communicates the flow path from the inflow port to the injection port with the outside of the arm grip. This is a characteristic feature.

[0009]

[Function] In addition to the original function of the arm grip for a bathtub of the present invention, which is to support the body by grasping it when entering and leaving the bathtub or while in the bathtub,
It also functions as a bubble injection nozzle. Therefore,
The number of bubble injection locations can be increased without increasing the number of bubble injection nozzles installed.

The arm grip for a bathtub according to the first aspect is used when bubble-containing water is introduced into the arm grip.

In the arm grip for a bathtub according to the second aspect of the present invention, hot water is introduced into the arm grip, air is sucked in the arm grip, and the water is jetted out as bubble-containing water.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the present invention will be described below with reference to the drawings. Fig. 1 is a plan view of the arm grip for a bathtub according to an embodiment of the present invention, Fig. 2 is a right side view of the same, Fig. 3 is a rear view of the same, and Fig. 4 is taken along line 4-4 in Fig. 1. The sectional view, FIG. 5, FIG. 6, and FIG. 7 are explanatory diagrams of the construction state of the arm grip for a bathtub.

This arm grip 10 for a bathtub has an arm grip main body 1 of a size that can be grasped by a bathtub user.
2, and a bathtub circulation piping connection part 14 and a mounting part 16 provided on the back surface of the arm grip main body 12 (see FIG. 2).
, an injection nozzle 18 provided on the other side of the arm grip body 12, an air suction port 20 bored in the upper surface of the arm grip body 12, and the like. Reference numeral 16a represents a bolt insertion hole drilled in the mounting portion 16.

A male screw is provided on the outer peripheral surface of the bathtub circulation piping connection portion 14. An inlet 22 is provided from the bathtub circulation piping connection section 14 . Arm grip body 12
, the cavity 2 is opened from the side where the injection nozzle 18 is provided.
4 is bored, and the inlet 22 and the cavity 24 are communicated through a communication opening 26 and a venturi nozzle 28 screwed into the opening 26. The air intake port 20
communicates the cavity 24 with the outside of the arm grip main body 12.

A short cylindrical spring retainer 3 is provided in the hollow portion 24.
0 is screwed together, and a nozzle holder 32 is screwed onto the inner peripheral side of the spring holder 30.

This nozzle holder 32 is equipped with a concave spherical seat 34, and a convex spherical portion 36 provided on the rear side of the injection nozzle 18.
is in slidable contact with the concave spherical seat 34. The convex spherical portion 36
The spring 3 is used to bias the ball in the direction of pressing the concave ball seat 34.
8 is installed. This spring 38 has one end in contact with the inner surface of the convex spherical portion 36 and the other end in contact with the inward flange portion 30a of the spring presser 30. 30b is spring presser 3
This is an opening drilled at 0.

As shown in FIG. 7, the arm grip for a bathtub constructed as described above is constructed by inserting the bathtub circulation piping connection part 14 into the arm grip mounting hole 44 formed in the side wall 42 of the bathtub 40, and Insert the bolt 4 into the bolt insertion hole 16a of the mounting part 16 and the bolt insertion hole 46 of the bathtub side wall.
8, tighten the nut 50, and further tighten a nut (not shown) to the bathtub circulation piping connection part 14, thereby fixing it to the bathtub side wall 42.

In this bathtub arm grip 10, hot water in the bathtub is introduced into the inlet 22 through piping, and is further jetted out through the venturi nozzle 28, the cavity 24, the opening 30b, and the injection nozzle 18. Due to the negative pressure generated when this hot water is injected from the venturi nozzle 28, air is sucked in from the air suction port 20, and bubble-containing water is injected from the injection nozzle 18 into the bathtub.

FIGS. 5 and 6 show an example of a piping system for a bathtub equipped with this arm grip 10 for a bathtub. As shown in FIG. 6, hot water in the bathtub 40 is led to the inlet 22 of the bathtub arm grip 10 via a water intake port 52, a pipe 54, a circulation pump 56, and pipes 58 and 60. Another pipe 62 branches off from the pipe 58, and this pipe 62 is connected to a normal bubble injection nozzle 64 attached to the side wall surface of the bathtub 40. 66 is a pipe for introducing air into the bubble injection nozzle 64, and 68 is an air suction port.

In the bathtub arm grip shown in this embodiment, the convex spherical portion 36 of the injection nozzle 18 is connected to the nozzle retainer 3.
Since it is slidably locked to the second concave spherical seat 34, the injection direction of the injection nozzle 18 can be changed freely. For this reason, the chest, abdomen, flanks, thighs, etc. of the bather in the bathtub 40,
Bubble jets can be directed to desired areas, such as the legs. In addition, when the bubbles are ejected downward along the bathtub side wall 42, the air bubbles ejected from the arm grip 10 descend along the bathtub side wall 42, then reverse at the bottom of the bathtub and blow up from the bottom of the bathtub. Other types of jet configurations can also be formed.

In the above embodiment, the arm grip for the bathtub is provided with an air mixing function, and the air sucked in from the air intake port 20 is ejected from the injection nozzle 18 as bubble-containing water, but in the present invention, Such an air mixing function may be omitted, and air may be mixed in advance with the hot water introduced into the arm grip using a line mixer or the like. However, if the arm grip has an air mixing function and an air intake port is formed in the arm grip as in the above embodiment, the clean and high temperature air in the bathroom can be mixed, and the ejected water can be mixed. It is possible to prevent dirt and temperature drop.

In the above embodiment, the arm grip is attached to the inner surface of the long side of the bathtub, but it may also be attached to other parts of the inner surface of the bathtub (for example, the corners or the inner surface of the short side) or the flange of the bathtub. It's okay to be beaten.

[0023]

[Effects of the Invention] As described above, the arm grip for a bathtub of the present invention has the function of a bubble ejecting nozzle in addition to the original function of the arm grip. The number of eruption points can be increased. Furthermore, it is also possible to form various ejection forms different from conventional bubble ejection nozzles.
