Description

[Detailed description of the invention] The present invention relates to a bubble ejector for a bubble bath that ejects bubbles generated by a bubble generator into a bathtub, and is capable of ejecting bubbles in any direction. By pointing in the direction, the heated flow from the bathtub can be diffused, eliminating the discomfort and danger caused by the flow of hot water.

The embodiment of the present invention will be described in detail below. Figure 1 shows the overall configuration of a bubble bath, where 1 is a bathtub, 2 is a circulation bath pot, and 3 is a bathtub.
4 is an upper circulation pipe connecting the bathtub 1 and the brewing port side of the pot 2;
Reference numerals 5 and 6 indicate a lower circulation pipe, and 5 and 6 indicate a discharge pipe and a suction pipe inserted into the circulation pipes 3 and 4 in the form of double pipes, respectively.

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 5 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 widened in one direction by a curved surface 21a in a direction perpendicular to the pin axis, and as shown in FIG. When the nozzle 20 is tilted about the pin 22 so that it is approximately half blocked,
The portion 21b expanded by the curved surface 21a is the lid 2, which will be described later.
A foam spout 21 faces the outside of
At the same time, it functions to guide the user into the bathtub 1.

23 is a ring-shaped lid that holds the pin 22 and prevents the nozzle 20 from falling off, and a pin groove 24 in which the pin 22 slides.
This is provided.

25 is an O-ring fitting groove provided at the end of the nozzle fitting part 17, 26 is an O-ring, 27 is a washer-fitting large groove provided on the outside of the groove 25, and 28 is a washer, which holds the O-ring 26 on one side. At the same time, the other surface is a surface on which the pin 22 slides.

Thus, the nozzle 20 can rotate 3600 degrees by sliding the pin 22 in the groove 24, and can swing approximately 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 and applies a frictional force to the nozzle 20, thereby preventing the nozzle 20 from returning to the straight direction due to the discharge pressure even if the direction is changed.

29 is a knob formed at the tip of the nozzle 20 in the same direction as the pin 22, and 30 is a pressure relief hole formed by cutting out the side of the nozzle tip. This is to release the bubble ejection pressure from 7 into the bathtub 1.

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 B, 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.

Further, as shown in the third diagram, the nozzle 20 is rotated around the pin 22 as an axis.
The direction in which the spherical surface 20a closes the tip of the connecting cylinder portion 16 (direction a)
When the nozzle 20 is rotated, the bubbly water from the discharge pipe 5 flows into the expanded portion 2 along the curved surface 21a depending on the degree of rotation.
1b and into the bathtub 1 separately from the bubble spout 21, this bubble water collides with the hot water flow sent from the upper circulation pipe 3 due to the heating of the bath pot 2, and the temperature of this hot water flow increases. The temperature drops moderately, and the forced flow of bubbling water spreads throughout the bathtub 1, and it also gently rises from the bottom of the bathtub, eliminating the unpleasant sensation of sudden heat only at the top of the bathtub, unlike in conventional baths. Alternatively, there is no danger and it is extremely comfortable to reheat the bath while taking a bath.

Moreover, at this time, the outflow of the heated flow is not hindered in any way, so
There is no risk that poor circulation will occur or that the thermal efficiency of the bathtub 2 will decrease.

Note that when the nozzle 20 is turned in the opposite direction (direction b), the foam outlet 21 is expanded at the curved surface 21a at the portion 2.
1b always faces the inside of the connecting tube 16, so that the bubble can be ejected from the tip of the foam outlet 21 and its direction can be changed as described above.

In summary, the present invention involves inserting the discharge pipe from the pump into the upper circulation pipe that connects the bathtub and the bathtub, providing a hemispherical concave nozzle fitting part on the main body connected to the discharge pipe, and creating a bubble in the center. By fitting a substantially spherical foam ejecting nozzle with a spout formed therethrough into the nozzle fitting part and holding it with a lid, the nozzle can be rotated 3600 degrees around its central axis and can be freely swung. The base end of the foam spout is configured so that one side is expanded so that when the nozzle is directed in a certain direction, the expanded portion faces the outside of the lid, so that the foam can be directed in any direction. It also has great practical effects, such as when used simultaneously with a bath pot, the heated flow from the pot is diffused by bubbles, allowing for gentle boiling from the bottom of the bathtub, allowing for a comfortable bath. be.
