Description

[Detailed Description of the Invention] The present invention relates to a bubble ejector for a bubble bath that squirts bubbles generated by a bubble generator into a bathtub.

Conventionally, this type of foam ejector in which the direction of the bubbles can be changed arbitrarily is known from Utility Model Publication No. 7015/1980, etc., but this type of directionally variable nozzle has been designed to use the ejecting force of bubble water from the pump. (Do not return to the original direction (straight direction))
- It is necessary to apply an appropriate braking force (frictional force) to the nozzle, and many of them use an O-ring, such as Utility Model Publication No. 51-27117.

However, when forming such a fitting groove of 0 mm/g, the rotation of the nozzle is performed by its spherical part, and therefore the nozzle support side is also formed in a spherical shape, so it is difficult to cut out the resin mold. , it is not possible to simultaneously mold the O-ring insertion groove with a mold,
Post-processing by boring was required.

Therefore, when the O-ring groove B is formed in the direction of the die-cutting direction of the nozzle support A as shown in Fig. 7, when the nozzle C rotates, the O-ring D is pulled and twisted, making it difficult to rotate the nozzle smoothly. There were some difficulties.

The present invention solves these difficulties, makes it easier to form the O-ring groove, prevents the O-ring from being twisted even when the nozzle rotates, and furthermore, by orienting the nozzle in a predetermined direction, the bathtub can be easily removed from the bathtub. The purpose of this invention is to provide a rational assembly structure for a foam ejector that can be used to mix aerated water into a heated stream of water, and examples thereof will be described in detail below.

Figure 1 shows the overall configuration of a bubble bath, where 1 is a bathtub, 2
3 is a circulation type bath pot, 3 is an upper circulation pipe connecting the bathtub 1 and the outlet side of the pot 2, 4 is a lower circulation pipe, and 5 and 6 are both circulation pipes 3.
.

Reference numeral 8 denotes a bubble generator provided in the middle of the discharge pipe 5, and is composed of an air suction pipe 9 communicating with the outside air and an ejector 10.

Reference numeral 11 denotes a foam ejector attached to the tips of the upper circulation pipe 3 and the discharge pipe 5.

2 to 6 show details of the foam ejector 11,
Reference numeral 12 denotes a fixture that is fixed to the bathtub wall 13 and has a circulation port 14 that communicates with the end of the upper circulation pipe 3. Reference numeral 15 indicates a connecting cylinder part 16 that is fitted and connected to the tip of the discharge pipe 5 in the center, and the connecting cylinder. Part 1
A hemispherical concave nozzle fitting part 17 is formed in series with the tubular wall 13, and the periphery thereof is connected to the tub wall 13 by screws 18, the peripheral part of which is connected to an appropriate number of bosses 19 protruding from the fixture 12. 20 is a spherical foam ejecting nozzle that passes through a foam ejector 21 having approximately the same diameter as the inner diameter of the connecting cylinder portion 16 in the center, and a pin 22 is implanted on the center line of the spherical portion. .

The base end side of the foam ejector 21 is expanded on only one side by a curved surface 21a in a direction perpendicular to the pin axis.

A ring-shaped lid 23 holds the pin 22 to prevent the nozzle 20 from falling off, and is provided with an annular pin groove 24 in which the pin 22 slides.

25 is an annular O-ring fitting groove provided at the end of the nozzle fitting part 17, 26 is an O-ring, 27 is an annular washer fitting groove provided on the outside of the groove 25, and 28 is a ring-shaped washer; One side holds the O-ring 26, and the other side serves as a surface on which the pin 22 slides.

Thus, the nozzle 20 can rotate 360 degrees by sliding the pin 22 in the groove 24, and can swing about 45 degrees on both sides about the pin 22 as an axis.

Note that the O-ring 26 comes into elastic contact with the spherical surface 20a of the nozzle 20 to apply a frictional force to the nozzle 20.

The circulation port 14 is opened into the bathtub 1 around the nozzle fitting part 17 of the main body 15, and the inside of the connecting cylinder part 16 is connected to the cylinder part 16.
Several bypass holes 2 are formed near the boundary between the and nozzle fitting part 17.
9 communicates with this opening 30.

In such a configuration, when the pump 7 is operated, the pump 7
Air is mixed in the water stream discharged from the bubble generator 8, and the bubbles are ejected from the nozzle 20 into the bathtub 1.

In order to change the blowing direction of the bubbles at this time, it is sufficient to change the direction of the nozzle 20, and since it can swing around the pin 22, and the bottle 22 itself can rotate 360 degrees within the groove 24, A combination of the two enables three-dimensional direction conversion.

Therefore, the foam can be applied to any part of the body to enhance the pine surge effect.

Moreover, if the water is ejected diagonally downward, the inside of the bathtub 1 can be sufficiently stirred, and the temperature of the water can be made uniform above and below.

When the direction of the nozzle is changed in this way, the nozzle 20
Since the ring 26 constantly applies the frictional force, the nozzle 20 is prevented from returning to its original direction (straight direction) due to the water pressure.
Since the nozzle 20 is held on one side of the nozzle 8, it will not be pulled and twisted by the spherical surface of the nozzle, and the direction of the nozzle 20 can be changed extremely smoothly.

Moreover, the other surface of the washer 28 acts as a sliding surface for the pin 22, and the rotation of the pin 22 becomes smooth.

Both the O-ring fitting groove 25 and the washer fitting groove 27 can be formed at the same time in the same direction as the hemispherical fitting part 17, so they can be manufactured at low cost.

By the way, the nozzle 2 is rotated around the pin 22 as shown in FIG.
When the nozzle 20 is rotated in the direction (direction a) in which the spherical surface 20a of No. 0 closes the tip of the connecting cylinder part 16, the bubble water from the discharge pipe 5 flows from the bypass hole 29 to the open part 3 according to the degree of rotation.
This bubbly water is stirred and mixed with the hot water flow that is sent to the upper circulation pipe 3 due to the heating of the bath pot 2, so that the temperature of the hot water flow drops moderately and rides on the forced flow of the bubbly water. The heat is evenly distributed throughout the bathtub 1, and is also gently raised from the bottom of the bathtub.

In addition, when the nozzle 20 is turned in the opposite direction (direction b), the foam jetter 21 always faces into the connecting cylinder part 16 at the part expanded by the curved surface 21a, so that the bubble water flows into the bypass hole 2.
As described above, the bubbles can be ejected from the nozzle tip and their direction can be changed without the bubbles flowing out to the 9 side.

However, if the pin 22 is not provided and the nozzle 20 is moved in all directions using only the spherical surface, it becomes extremely difficult to find the direction of the nozzle to block the bubble flow with a part of the spherical surface in order to perform the above-mentioned reheating stirring action. However, in the present invention, by changing the direction around the pin 22, the injection from the spout 21 and the reheating stirring can be operated selectively, making it extremely easy to use. Ta.

As described above, in the foam ejector of the present invention, each surface of the washer 28 effectively acts on the O-ring 26 for nozzle braking and the pin 22 essential for the reheating stirring function, and the direction change of the nozzle 20 is extremely smooth. The washer, OIJ ring, and pin are arranged in an extremely rational manner, and the O-ring is not twisted, and no post-processing of the O-ring fitting groove is required during production. effective.
