Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an apparatus for generating air bubbles in a bathtub, particularly for health purposes. The present invention is mainly suitable for use in general household baths, so-called indoor baths.

〔overview〕

The present invention is a bubble generator with a structure in which an inlet, an electric pump, a water pipe, and a nozzle are mounted in a single housing that can be carried into a bathtub. of,
By attaching it so that it rotates at a predetermined angle and moves upward, it generates less splash and noise during use, and allows the bubbles to be comfortably applied to desired areas of the human body. .

[Conventional technology]

It is known that by directly contacting hot water in a bathtub with an ultrasonic oscillator or by mixing compressed air, air bubbles generated in the hot water are applied to the surface of the human body to improve the health benefits of bathing.

The present applicant has filed Utility Application No. 84371 (1983).
We implemented a device with a casing shape that can be carried into a bathtub, as disclosed in Publication No. 149330, and a three-way nozzle attached. This device is easy to use in bathtubs, so it has been well received by ordinary households.

[Problem that the invention attempts to solve]

In the above device, nozzles were installed above and below the water surface of the bathtub, but one nozzle below the water surface is sufficient for the foaming effect of the hot water, and this foaming effect by the nozzle below the water surface is popular. . On the other hand, a nozzle above the water surface generates droplets and noise due to the ejected water flow.

An object of the present invention is to improve on this point and provide a bubble generator that can be brought into a bathtub and can comfortably apply bubbles to desired areas of the human body while generating less splash and noise.

[Means for solving problems]

This invention consists of an inlet, an electric pump, a water pipe,
The nozzle and the nozzle are mounted in one casing, and the structure is such that hot water in the bathtub is sucked in from the suction port, and the water flow ejected from the nozzle generates air bubbles in the bathtub.
The bubble generator is carried into a bathtub and is used with its bottom part touching the inner bottom surface of the bathtub and its top part protruding above the water surface. In use, the nozzle is installed at a position below the water surface of the hot water in the bathtub, and the nozzle has a first end open, a second end connected to the water pipe, and a third end connected to the intake port, so that the nozzle is connected to the water flow. The present invention is characterized in that it includes a three-way structure for mixing the air taken in from the intake port, and that the nozzle is mounted so as to rotate and move in the vertical direction.

Preferably, an air intake port is provided in the upper portion projecting above the water surface, and the air intake port and the third end of the three-way structure are connected by an air pipe.

Adding a foaming agent to hot water in a bathtub and using this device will activate foaming.

[Effect]

Since one nozzle is located below the water surface when in use, less splash and noise are generated when water is ejected from the nozzle.

Since the nozzle is attached to the housing so that the direction of the water jet can be varied and is located below the water surface, the removal of the bubbles can be adjusted so as to appropriately hit the desired part of the bather's body.

If the nozzle's position below the water surface can be moved up and down, even if the water level in the bathtub changes, more appropriate air bubbles will be applied to the body.

〔Example〕

Next, an embodiment of the present invention will be explained with reference to the drawings.

FIG. 1 shows a partially cutaway perspective view of a device according to an embodiment of the present invention, and FIG. 2 shows a structural explanatory diagram using a schematic cross-sectional view of the device according to the embodiment.

The device of this embodiment includes a suction port 1 equipped with a filter 11, an electric pump 2 that uses an external vane 12 to boost the pressure of hot water 23 drawn from the suction port 1, and a pump cover 13 that surrounds the pump 2.
A water pipe 14 made of a high-pressure flexible material connected to the outlet 3A of the pressure chamber 3 configured between
A nozzle 4 connected to an output port 4 is mounted in one housing 5, and hot water 23 in the bathtub is sucked in from the suction port 1, and a water flow shown by an arrow 24 from the nozzle 4 generates air bubbles in the bathtub. The structure is such that the casing 5 is brought into the bathtub by holding the head 5A, which is the upper part of the casing 5, so as to be in contact with the inner bottom surface 25 of the bathtub, and with the head 5A protruding above the water surface 26. It is what you use.

The features of the present invention are as follows.

That is, as shown in FIG. 2, one nozzle 4 is mounted on the housing 5, and when in use, the nozzle 4 is provided at a position below the water surface 26 of the hot water 23 in the bathtub. .

Furthermore, as shown in the nozzle assembly sectional view of FIG. 3, the nozzle 4 has a first end 31 of the front piece 41 open and a second end 32 of the rear piece 42 connected to the water pipe 14 shown in FIG. The third end 33 is connected to the suction port 7 provided in the head 5A of the housing 5 via the air pipe 15 shown in FIG. 2, and the air sucked from the suction port 7 is mixed with the water flow. Contains structure.

The front piece 41 and the rear piece 42 of the nozzle 4 have the structure shown in FIGS. 4 and 5, respectively, and the first end 31 is surrounded by an opening edge 44 and connected to the second end 32. It is a tubular structure configured to have a large inner diameter. Third end 3 inside joint part 46
3 is connected to a chamber 45 of a concentric structure with this tubular structure,
This chamber 45 has a large number of holes 47 provided in the front piece 41.
is connected to the tubular structure at the first end 31 side. That is, the holes 47 cause the air from the chamber 45 to be drawn into and mixed with the water flow passing through the tubular structure. Furthermore, as shown in FIG.
3 and screwed to the holder 51, the direction of the opening edge 44 relative to the holder 51 can be changed. Therefore, the direction of the water stream jetted from the first end 31 is variable.

In FIG. 1, the opening 5B to which the holder 51 for holding the nozzle 4 of the housing 5 is attached is
1 is attached so that it can be moved up and down.
This structure is shown in FIG.

In FIG. 6, grooves 51A are provided on both sides of the holder 51, into which the edges of the opening 5B of the housing 5 fit, and the holder 51 allows the nozzle 4 to move in the vertical direction using these grooves as a guide. . Therefore nozzle 4
Since the rear piece 42 rotates, the water pipe 14 and the air pipe 15 connecting the upper and lower pressure chambers 3 and the intake port (not shown) are made of flexible material.

As shown in FIG. 2, hot water enters the inner chamber 5C of the casing that surrounds the outside of the pump cover 13 when the pump cover 13 is in use. In this example device, from the viewpoint of aesthetic appearance,
As shown in FIG. 6, fixed slide plates 52 are attached to the upper and lower sides of the holder 51, and by combining the free slide plates 53 with the fixed slide plates 52 and the respective hinges 52A and 53A, the opening 5B is shielded. Ru.

By rotating the nozzle and moving up and down in this way, the bubble generator, which has a casing that can be carried into a bathtub, can freely direct the bubbles without generating any splash or noise. It can be adjusted to

Furthermore, by adding a foaming agent to the hot water in the bathtub, the effectiveness of using the device of this embodiment is further improved.

Foaming agents include, for example, additives for health baths based on polyethylene glycol as disclosed in Japanese Patent Application No. 59-21370 (disclosed in Japanese Unexamined Patent Publication No. 60-166607), to which sodium hydrogen carbonate and anhydrous sodium sulfate are added. Agents etc. are suitable.
