The present invention relates to a bubble generator used.

[0002]

2. Description of the Related Art Conventionally, in this type of bubble generator, hot water is sucked from a bathtub and air from the atmosphere by a pump, and the air is pressurized and dissolved in the hot water in the pump. And in order to separate the air that was not dissolved in the pump from the hot water,
A dissolution tank is provided between the pump and the bath.
After the undissolved excess air and hot water are separated in the dissolving tank, hot water containing the dissolving air is discharged into the bathtub from a spout provided in the bathtub. Therefore, fine air bubbles are generated in the bathtub, and the hot water becomes milky. On the other hand, the excess air separated in the dissolving tank is discharged out of the apparatus.

[0003]

When the hot water stored in the above-mentioned bathtub uses water containing various components such as well water, for example, the hot water may affect the human body. In some cases, certain germs were mixed in or hot water emitted an off-flavor.

[0004] However, the above-mentioned bubble generating device cannot satisfy the above-mentioned sterilizing effect and deodorizing effect of the hot water, although it can satisfy the heat retaining effect of the hot water and the promotion of blood circulation.
Therefore, in this case, it is necessary to add a chemical having a bactericidal action to the hot water, or to add a bathing agent or a deodorant having an aroma action to remove the unpleasant odor of the hot water, which is very troublesome. There is such a problem.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to make it possible to surely generate fine bubbles and to put a chemical or a deodorant into a liquid storage tank. It is an object of the present invention to provide a bubble generator capable of sterilizing and deodorizing a liquid without performing the same.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is embodied in a bubble generating device for a bath tub will be described below with reference to FIGS.

FIG. 1 is a schematic circuit diagram of a bubble generating apparatus according to the present embodiment. As shown in the drawing, hot water W as a liquid is stored in a bathtub 1 as a liquid storage tank. In addition, a suction port 2 and a jet port 3 are formed vertically on the side wall of the bathtub 1. A pump 5 is connected to the suction port 2 via a suction pipe 4. An ozone gas generator 6 for generating ozone gas is connected to a suction port of the pump 5. In this embodiment, the pump 5 is constituted by a Wesco pump.

As shown in FIG. 2, the wesco pump 5
A rotor 8 is rotatably accommodated in a casing 7 by a motor (not shown). A plurality of blades 9 are formed in the rotor 8, and a large number of grooves 10 are formed in the outer periphery thereof. When the rotor 8 is rotated, friction is generated between the blade 9 and the groove 10, so that the ozone gas and the hot water W are sucked into the casing 7. The pressure of the wesco pump 5 is set at a low pressure of 3 kg / cm ² .

As shown in FIG. 1, a dissolving tank 11 is disposed downstream of the pump 5, and the pump 5 and the dissolving tank 11 are connected by an inflow pipe 12. As shown in FIG. 3, the melting tank 11 includes a body 11a and a cup 11b. Body 1
The inflow port 14 and the discharge port 15 are formed on the side wall 1a so as to face each other. An outflow port 16 is formed in the center of the body 11a upward from a right angle direction.
Has been communicated with.

The upper portion of the discharge port 15 on the inner side of the inner wall of the body 11a is opened. And, between the discharge port 15 and the jet port 3 of the bathtub 1,
The discharge pipe 17 is in communication. The cup 11
b is fastened and fixed at the upper part of the body 11a via a packing 18. An opening is formed in the upper part of the cup 11b, and the reducing port 19 and the suction pipe 4 are connected by a reducing pipe 20.

As shown in FIG. 4, a small hole nozzle 21 is disposed in the vicinity of the reducing line 20 where it merges with the suction line 4. This fine-hole nozzle 21 is a disc-shaped sheet packing 2 having an inflow hole 22 and a discharge hole 23 having different diameters.
4 is formed. The inflow hole 22 is formed in a tapered shape with a smaller diameter toward the discharge hole 23. Also, the discharge hole 2
Numeral 3 is formed with the same diameter as the diameter of the minimum diameter portion of the inflow hole 22, and the inflow hole 22 and the discharge hole 23 are in communication.

As shown in FIG. 5, the outlet 3
A is provided with a net filter 25. Although not shown, the suction port 2 is also provided with a net filter coarser than the net filter 25 coated on the ejection port 3.

The outlet 3a and the inlet 3b are connected by a tapered portion 3c.

Next, the operation of the air bubble generator configured as described above will be described. First, when the pump 5 is driven, hot water W in the bathtub 1 is sucked into the pump 5 by the suction force of the pump 5, and ozone gas generated by the ozone gas generator 6 is sucked into the pump 5, respectively. Ozone gas is dissolved under pressure. Then, the hot water W containing the dissolved ozone gas is pressure-fed into the cup 11b from the inflow port 14 and the outflow port 16 via the inflow pipe 12.

At this time, the ozone gas not dissolved in the hot water W in the melting tank 11 is separated from the hot water W. In this embodiment, the outflow port 16 serving as the outlet of the inflow port 14 is
Since the hot water W is formed in an upward direction different from the direction toward the discharge port 15, the flow of the hot water W is upward. As a result, the excess ozone gas is not discharged from the discharge port 15 together with the hot water W. Therefore, only the hot water W containing the dissolved ozone gas is discharged from the discharge port 15.

The particles of surplus ozone gas sucked into the suction pipe 4 are finer than the particles of surplus ozone gas discharged from the dissolving tank 11. because,
Since the diameter of the inflow hole 22 of the small hole nozzle 21 is smaller toward the discharge hole 23, the flow speed of the excess ozone gas is increased when the excess ozone gas passes through the inflow hole 22. Then, in that state, excess ozone gas is injected from the discharge holes 23, and the hot water W
, The particles of the excess ozone gas are fragmented. Then, the finely divided excess ozone gas is sucked into the suction pipe 4 and mixed with the hot water W.
It is dissolved under pressure.

Therefore, even if the pressure of the pump 5 is set to a very low pressure of 3 kg / cm ² , the ozone gas can be dissolved under pressure because the excess ozone gas is subdivided. As a result, in this embodiment, the electric power of the motor for driving the pump 5 can be reduced, so that
Very economical.

The hot water W from which the excess ozone gas has been separated is
The gas flows into the jet port 3 from the inlet 3 b of the jet port 3 through the discharge pipe 17. Thereafter, when the hot water W reaches the tapered portion 3c, the flow speed of the hot water W is reduced. Then, in a state where the flow speed is reduced, the hot water W is discharged from the outlet 3a of the outlet 3 through the net filter 25 at a low speed into the bathtub 1. Therefore, cavitation occurs in the hot water W without fail,
Fine bubbles are surely generated in the bathtub 1.

That is, in this embodiment, the outlet 3
The opening area of a is formed larger than the opening area of the inlet 3b, so that a separate speed reduction member or the like is not provided.
The flow speed of the hot water W can be reduced. as a result,
The number of parts and the assembling work are reduced, and the manufacturing cost can be reduced.

Further, in the present embodiment, since the ozone gas is dissolved in the hot water W discharged to the bathtub 1, a disinfectant, a deodorant and the like are injected into the bathtub 1 by a strong oxidizing action peculiar to the ozone gas. The hot water W can be easily sterilized and deodorized without performing. As a result, the inside of the bathtub 1 can always be kept in a sanitary state, and more comfortable bathing can be performed.

It should be noted that the present invention is not limited to the above embodiment, and may be configured as follows without departing from the spirit of the invention. (1) In the above-described embodiment, the liquid storage tank is embodied in the bathtub 1, but this is embodied in a water tank or the like, or water or a liquid containing various components is used instead of the hot water W as the liquid.
