Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a bubble generating bathtub in which two types of bubbles having different diameters are generated by a single bubble generating means.

[Prior Art] In a bubble-generating bath in which two types of bubbles having different diameters have been conventionally generated and are switched to be supplied to a bath, for example, Japanese Patent Application No. 62-13608.
As in No. 3, the bathtub and most of the components of the bubble generating means were separated. That is, by only attaching the nozzle part, which is one member of the bubble generating means, to the bathtub, the other parts of the bubble generating means such as the air inlet, various valves, accumulators, switching valves, motors, pumps, etc. It was all housed in the device itself, and was usually installed outside the bathroom. The bathtub installed in the bathroom and the apparatus main body installed outside the bathroom were connected by three pipes (that is, three pipes for jet jet bubble discharge, fine bubble discharge, and suction).

[Problems to be solved by the invention] However, when fine bubbles are generated, it is necessary to mix air and water at a fixed ratio and suck the mixture, and if this ratio changes, the discharge performance (characteristics) of the fine bubbles also increases. It will change subtly, and therefore the air intake amount must be accurate. However, in the prior art, since the air suction port for fine bubbles is provided in the device body 6, the level of the installation location of the bath 8 and the level of the installation location of the device body 6 are different from each other. The head pressure (that is, the vertical distance between the water surface of the bathtub and the air inlet for fine bubbles) applied to the portion of the air inlet for fine bubbles that is equipped also differs depending on the installation location (ie, in FIG. 2). WL indicates the water level of the bathtub 8, and different from the waterhead pressure H _{1 at} the installation position of the bathtub 8 on the left side and the waterhead pressure H _{2 at} the installation position of the bathtub 8 on the right side, a water head pressure H ₃ is generated), The amount of diaphragm has to be adjusted so as to match the installation location, and the adjustment is not stable, resulting in unstable performance. Further, since the accumulator is installed in the apparatus main body 6, it is difficult to return the exhaust air of the excess air from the accumulator and the drainage accompanying it to the bathtub 8 and the construction is troublesome. Further, since almost all the parts are incorporated in the device body 6, the device body 6 becomes large, which not only requires a large space on the outer wall side of the bathroom but also spoils the aesthetics of the house.

The present invention was devised in view of the above-mentioned problems of the conventional example, and the purpose thereof is stable performance, easy construction, and further miniaturization of the device body, and the outer wall side of the bathroom. It is to provide a bubble generation bathtub that does not require a large space and does not spoil the aesthetics of the house.

[Means for Solving the Problems] In order to achieve the above-mentioned object of the present invention, a bubble generation bath of the present invention includes fine bubbles generated by pressurizing and dissolving a gas in a liquid and depressurizing the liquid, In a bubble generation bath in which both of the jet jet bubbles generated by entraining gas when ejecting pressurized water from the injection nozzle 1 are generated by switching by the bubble generation means 2, the bubble generation means 2 uses only a pump and a motor. Equipped device body 6 and other fine air bubble air inlet 10 and accumulator 1
And a component 7 required for bubble generation including 1 and a component 7 required for bubble generation other than the components provided in the device body 6 are attached to the bathtub 8 and the bathtub 8 and the device body 6 are used for suction. It is configured to be connected by two pipes 9 for discharge.

[Operation] In the present invention, however, fine bubbles are generated in the bathtub 8 by the bubble generating means 2 or are switched to jet jet bubbles and discharged into the bathtub 8. The bubble generating means 2 is composed of a device body 6 equipped only with a pump and a motor and other components 7 necessary for generating bubbles, and components 7 other than the components provided in the device body 6 required for bubble generation. 2 is attached to the bathtub 8, and the bathtub 8 and the device body 6 are connected by two pipes 9 for suction and for discharge, so that the device body 6 can be constructed with two pipes 9 and the construction is simplified. In addition, it is not necessary to adjust the head pressure applied to the air suction port 10 for fine bubbles, and the accumulator 11
The adjustment is no longer necessary.

[Examples] The present invention will be described in detail below with reference to Examples. FIG. 1 shows one embodiment of the present invention. The bubble generating bath according to the present invention includes fine bubbles (a bubble diameter of about 10 μm) generated by pressure-dissolving a gas in a liquid and depressurizing the liquid, and entrains the gas when the pressurized water is discharged from the jet nozzle 1. Both of the jet jet bubbles (bubble diameter of about 0.8 mm) to be generated are generated by switching by the bubble generating means 2. The bubble generating means 2 is a device main body 6 equipped only with a pump and a motor and other parts 7 required for generating bubbles.
(A flow path switching valve 12 such as an electromagnetic valve required for switching bubbles, an accumulator 11 for separating excess gas that has not been completely dissolved in liquid by fine bubbles from the liquid,
Accumulator exhaust valve 13, fine air bubble inlet 10, air solenoid valve 14, air inlet 15, water inlet 1
6, nozzle 17 for fine bubbles, nozzle 1 for jet jet
Etc.) and. Here, components 7 other than the components provided in the apparatus body 6 necessary for generating bubbles are attached to the side surface of the bath 8 (in this case, the fine bubble nozzle 17,
The jet jet nozzle 1 is mounted so as to penetrate the side surface of the bathtub 8). Each of the parts 7 is connected by a pipe, and further, the apparatus body 6 to which the parts 7 are attached and the bath 8 are connected by two pipes 9 of a suction pipe 9a and a discharge pipe 9b. is there. When the apparatus main body 6 is arranged outside the bathroom, only two pipes, the suction pipe 9a and the discharge pipe 9b, need be installed to penetrate the wall of the bathroom. The suction pipe 9a is a water suction part 16 attached to the bathtub 8.
Further, an air suction pipe 9c for fine bubbles having a tip as an air suction port 10 for fine bubbles is connected to the suction pipe 9a. The tip of the discharge pipe 9b is branched via a flow path switching valve 12 into a fine bubble discharge pipe 9d and a jet jet pipe 9e. Piping for discharging fine bubbles 9
An accumulator 11 is interposed in the middle of d, and a nozzle 17 for fine bubbles is provided at the tip of the accumulator 11. A jet nozzle 1 is provided at the tip of the jet jet pipe 9e, and an air suction pipe 9f having an air suction port 15 at the tip is connected to the jet nozzle 1.

A case where fine bubbles are generated in the bubble generation bath as described above will be described. Water in the bathtub 8 is sucked in from the water suction section 16. Using the suction force at this time, air is sucked from the air suction port for fine air bubbles 10 and mixed into water. Here, the solenoid valve 14 for air is set to open only when fine bubbles are generated, and the air is mixed by opening the solenoid valve 14 for air. This part is also equipped with an air amount control valve, and the air is sucked in after adjusting an appropriate amount. The gas-mixed water in which air and water are mixed is conveyed to the apparatus main body 6 through the suction pipe 9a and is pressurized therein to dissolve the air in the water. However, in order to increase the solubility, it is necessary to strictly adjust and mix 10 to 20 times the amount of air that is actually dissolved. The gas-liquid mixed water dissolved under pressure is sent from the discharge pipe 9b to the accumulator 11 via the flow path switching valve 12. Here, in order to further promote the dissolution of air into water, the undissolved air out of the extra mixed air in order to increase the solubility is exhausted from the accumulator exhaust valve 13, and the excess air is completely removed. By discharging (reducing pressure) from the fine bubble nozzle 17, only fine bubbles are deposited. If the excess air is not completely removed in the above operation, the large bubbles are discharged from the fine bubble nozzle 17 and the discharge amount of the fine bubbles is also reduced.
It is necessary to completely remove excess air. Excess air discharged from the accumulator 11 is not only air but also a small amount of water is simultaneously discharged. Therefore, it may be connected to the drain pipe, but may be returned to the bathtub 8.

Next, the case of jetting jet jet bubbles will be described.
Since the solenoid valve 14 for air is closed, the water sucked from the water suction portion 16 does not mix with air and is pressurized by the main body 6 of the device, and is jetted from the jet nozzle 1 through the discharge pipe 9b and the flow path switching valve 12. To be done. At this time, due to the action of the jet pump, the air is sucked from the air suction port 15 into the respective injection nozzles 1 through the air suction pipe 9f to form bubbles having a bubble diameter of about 0.8 mm and discharged from the jet nozzle 1. Here, the air suction port 15 is equipped with a check valve 19 so that the water in the bathtub 8 does not come out from the air suction port 15 even when the bathtub 8 is filled with water.

By the way, in the case of fine bubbles, it is necessary to suck in a fixed ratio of air with respect to the sucked amount of water, but in the conventional example, as described above, the positional relationship between the bath 8 and the apparatus body 6 is always constant. Since it does not occur (that is, it differs depending on the installation location), it was necessary to adjust the air intake amount according to the installation location, but by installing the air intake port 10 for fine bubbles in the bathtub 8 as in the present invention, Air inlet 10 for air bubbles and bath 8
The water level of is always maintained at a constant distance, and it should be adjusted to a constant value at the time of factory shipment. Also, since each part 7 except the pump and motor is equipped in the bathtub 8, all adjustments and maintenance can be performed by simply removing the apron or inspection port of the bathtub 8, and the state of bubbles in the bathtub 8 can be checked in the bathroom. Adjustment and maintenance can be done while checking, and parts can be easily replaced.

Although the embodiment shown in FIG. 1 shows an example in which the air suction port 10 for fine bubbles and the air suction port 15 are separately provided, the air suction pipe 9 for fine bubbles having the solenoid valve 14 for air is provided.
The tip of c is connected to the jet air suction pipe 9, and the air suction port 15 provided in the air suction pipe 9 is connected to the air suction port 1 for fine bubbles.
It may also be used as 0.

[Advantage of the Invention] In the present invention, the bubble generating means is composed of the apparatus main body equipped only with the pump and the motor, and other components necessary for generating bubbles, and other fine components other than the components provided in the apparatus main body. Since components necessary for generating bubbles, including an air intake port for bubbles and an accumulator, are attached to the bathtub, and the bathtub and the apparatus main body are connected by two pipes for suction and discharge,
Regardless of the position of the device and the bath, there is no need to adjust the amount of mixed air, and fine air bubbles can always be discharged in a stable state. As a result, it is sufficient to make adjustments at the time of shipment. Since the positional relationship between the accumulator and the bathtub can be made accurate regardless of the positional relationship between the main body and the bathtub, it is easy to return excess air exhausted from the accumulator and the accompanying drainage to the bathtub.
As a result, labor saving, simplification, and stabilization of operation can be achieved during construction. Also in terms of maintenance, it can be done in the bathroom, and can be adjusted in the bathroom while checking the bubble discharge state. Furthermore, the main body of the device is connected to the bathtub by two pipes, which saves the labor of construction and has a great effect on the prevention of construction mistakes.
