DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bubble bath apparatus having bubbles in a bathtub by circulating water with a pump.

[0002]

2. Description of the Related Art FIG. 7 shows a conventional bubble bath apparatus. That is, the hot water from the bathtub 1 is sucked by the water pump 2, and is spouted from the channel outlet 3 into the bathtub 1. At this time, air is also sucked in at the same time, and the amount of air is adjusted by the air suction mechanism 4. As a result, a bubble water stream is ejected from the flow path outlet 3. On the other hand, to raise the temperature of the hot water inside the bathtub, the hot water is heated by the gas burner 6 by flowing through the heating flow path 5 (for example, the actual hot water 2-12).
522).

[0003]

However, in the above-mentioned conventional structure, the bubble water flow ejected from the flow path outlet 3 is 3 to 5 times.
Since only bubbles of about mm and no function of changing the diameter of bubbles were used, only one kind of bubbles was provided, and the commercial value was somewhat unsatisfactory.

An object of the present invention is to provide a bubble bath apparatus having the function of generating bubbles of about 3 to 5 mm and fine bubbles of about several tens of microns from one jet nozzle. It is.

Another object of the present invention is to stabilize the performance of generating fine bubbles even when the installation height of the bathtub is different.

A further object of the present invention is to make it possible to easily adjust so that fine bubbles are generated even when the installation height of a bathtub differs for each manufacturer and each product type.

In FIG. 1 to FIG. 3, reference numeral 7 denotes a water tank, and the water tank 7 is provided with a water jet nozzle 8 and an air bubble jet means 10 constituted by an air pipe 9. Numeral 11 denotes a water flow decompressing means for decompressing the liquid in which the air is pressurized and dissolved. The water flow depressurizing means 11 urges a valve seat 13 provided with a slit 12 through a diaphragm 15 by a spring 14. The valve body 16 is formed. On the other hand, reference numeral 17 denotes a heat source unit, and a circulation pump 18 is provided in the heat source unit 17. The circulation pump 18 is provided with a bypass 20 having an ejector 19. Reference numeral 21 denotes a motor-operated valve of first switching means for switching the suction direction to the circulation pump 18 to the ejector 19 side and the return pipe 22. A suction pipe 24 having a manual valve 23 as a flow path resistance adjusting means is provided from the upstream side of the electric valve 21 to the ejector 19. The ejector 19 is provided with an electromagnetic valve 25 as an air introduction means and an air pipe 26. On the discharge side of the circulation pump 18, an electric valve 28 as a second switching means for switching the flow from the circulation pump 18 to the going pipe 27 and the bypass path 20 is provided downstream of the feed pipe 29. The feed pipe 29 is connected to the valve seat 13. An electromagnetic valve 31 is provided at the end of the air pipe 9 via a check valve 30. 32 is a heat exchanger, and 33 is a burner. Reference numeral 34 denotes fine bubbles, and reference numeral 35 denotes large bubbles. 36 is an arrow indicating a flow. 37 is a thermistor for detecting the water temperature of the return pipe 22. The configuration of the flow path resistance adjusting means 23 will be described with reference to FIG. 3. A cock 38 is provided in the middle of the flow path. A shaft 39 of the cock is provided with a groove 40 into which a driver or the like enters, and a mark 41 indicating an opening degree. FIG. 3 shows that the bathtub 7 is installed on the first floor. Reference numeral 42 denotes a bubble blowing device.

Next, the operation of the first invention will be described with reference to FIGS. When fine bubbles are generated, as shown in FIG. 1, the valve body 16 and the valve seat 13 of the water flow decompression means 11 are in a closed state, and only the slit 12 constitutes a flow path. The motor-operated valve 21 closes the return pipe 22, and the motor-operated valve 28 closes the going pipe 27 on the heat exchanger 32 side. When the circulating pump 18 is operated in such a state, the water flowing out of the circulating pump 18 flows to the feed pipe 29 and to the bypass path 20 side. At this time, due to the suction action of the ejector 19, the water in the return pipe 22 is sucked into the ejector 20 via the suction pipe 24 and the opened manual valve 23, and also the air is sucked through the electromagnetic valve 25. When the water is sucked in this way, the pressure on the suction side of the circulation pump 18 increases, and the circulation pump 1
The pressure on the discharge side of 8 also increases, and high-pressure water in which air has been dissolved is sent from the circulation pump 18 to the water flow reducing means 11 through the feed pipe 29. The water sent to the water flow decompression means 11 is rapidly depressurized by being ejected from the slit 12. As a result, the air dissolved at the time of high pressure becomes fine bubbles and is ejected to the water tank 7. At this time, the mark 41 of the manual valve 23 is set at the position 1F.

Next, the operation when a large bubble is generated will be described. When a large bubble is generated, the electric valve 21 closes the bypass 20, and the electric valve 28 also closes the bypass 20. The solenoid valve 25 is in a closed state. When the circulation pump 18 is operated in such a state, the water discharged from the circulation pump 18 is sent to the bubble water jetting means 10 via the heat exchanger 32. The sent water is jetted from the water jet nozzle 8 to the water tank 7. At this time, the pressure on the upstream side of the water ejection nozzle 8 increases due to the restriction of the water ejection nozzle 8. As a result, the force for lifting the diaphragm 15 upward increases, and the valve element 16 separates from the valve seat 13. In conjunction with this operation, when the water is jetted from the water jet nozzle 8 in such a state, the air is sucked from the air pipe 9 by the negative pressure at the time of jetting. The jet from the water jet nozzle 8 shears this air and jets it into the water tank 7 as bubbles of about 3 to 5 mm. The air suction path at this time is the electromagnetic valve 31, the check valve 30, and the air pipe 9. In this operation, the water discharged from the circulation pump 18 is supplied via the outflow pipe 27 and the feed pipe 29 to the bubble water jetting means 10.
Flows to

In this configuration, 2F (second floor) of bathtub 43
The operation at the time of generation of microbubbles at the time of installation is the same as the operation of the first invention. However, at the time of 2F installation, the pressure at the connection of the suction pipe 24 of the ejector 19 is stable at the position head of the bathtub 43 and the positive pressure Become. However, by setting the mark 41 of the cock 38 of the main valve 23 in FIG. 5 to the position of 2F, the flow path resistance becomes large and the suction pipe 24 of the ejector 19 becomes large.
Is negative pressure, the solenoid valve 25, air pipe 26
The air is sucked into the ejector 19 through the, and the fine bubbles can be stably generated.

Next, a third embodiment corresponding to the third invention will be described with reference to FIG. 44 is a flow path resistance adjusting means,
The valve opening adjusting means rotates the groove 46 of the shaft 45 with a driver or the like, so that the flow path 47 in the cock 45 rotates. The display means includes a mark 48 provided on the shaft 45 and a scale 49 indicating the height to the bathtub.

In this configuration, the flow path resistance adjusting means 44
Is provided with a scale 49 indicating the height up to the bathtub. By setting a mark 48 provided on the shaft 45 corresponding to the bathtub installation height to the scale, the suction pipe 24 of the ejector 19 is connected. By setting the pressure of the portion to a negative pressure, it is possible to stably generate fine bubbles as described above.
