Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a technology for sucking up floating matter such as grime floating on the water surface in a bubble generating device for a bathtub.

[Background Art] In a conventional bubble generator for a bathtub, as shown in FIG. The fine bubble generating nozzle 1 and the suction part 3 are connected through a circulation pipe 4 outside the bathtub 2, and the circulation pipe 4 is provided with an intake part 5, a pressurizing pump 6, and an accumulator 7 for removing coarse air bubbles. had been formed. When the pressure pump 6 is driven, the water in the bathtub 2 is sucked in from the suction part 3, the outside air is sucked in by the suction part 5, air is drawn into the water sucked in from the suction part 3, and the water in the bathtub 2 is sucked into the water by the accumulator 7. The bubbles are removed and fine bubbles are ejected from the fine bubble generating nozzle 1. In such a conventional example, pressurized water is rapidly returned to atmospheric pressure by the fine bubble generating nozzle 1, so that fine bubbles can be obtained, but there is no flow rate and only a small flow rate can be obtained. Therefore, problems such as floating matter such as limescale, grime, hair, etc., which are peculiar to the bathtub 2 equipped with the bubble generating device, float to the surface of the water, making the bathtub 2 dirty.

[Purpose of the invention] This invention has been made in view of the above points, and the purpose of this invention is to switch the water to the jet nozzle by operating the switching valve so that it can be used as a jet bath and also remove floating substances. To provide a bubble generator for a bathtub which can keep the bathtub clean.

[Disclosure of the invention] The bubble generating device for a bathtub according to the present invention is provided with a fine bubble generating nozzle 1 that generates fine bubbles and a suction part 3 that sucks water in the bathtub 2 in a bathtub 2. The suction part 3 is communicated with the circulation pipe 4 outside the bathtub 2, and the circulation pipe 4 is connected to the suction part 5,
A pressurizing pump 6 and an accumulator 7 for removing coarse air bubbles are provided, and the accumulator 7 of the circulation pipe 4
A switching valve 8 is disposed between the microbubble generation nozzle 1 and a jet nozzle 9 provided in the bathtub 2, and the switching valve 8 is connected to the jet nozzle 9 provided in the bathtub 2 through a branch pipe 10. pipe 11
is communicated with the jet nozzle 9 so that suction by the ejector action of the jet nozzle 9 works, and a suspended matter removing net 12 is placed in the middle of the suction pipe 11. By configuring as described above, the drawbacks of the conventional example can be overcome. It is resolved. That is, a switching valve 8 is disposed between the accumulator 7 and the fine bubble generation nozzle 1 of the circulation pipe 4, and the jet nozzle 9 provided in the bathtub 2 and the switching valve 8 are communicated through a branch pipe 10. 2
A suction pipe 11 that sucks floating matter A on the water surface is connected to the jet nozzle 9 so that suction by the ejector action of the jet nozzle 9 works, and a floating matter removal net 1 is installed in the middle of the suction pipe 11.
2, when the switching valve 8 is switched so that water is supplied to the branch pipe line 10, jet water is jetted from the jet nozzle 9 into the bathtub 2, and at the same time, the ejector action of the jet nozzle 1 causes the suction pipe 11 to be Water containing floating matter A on the water surface is sucked in and the floating matter A is collected by the floating matter removal net 12, and it can also be used as a jet bath and also removes floating matter A to clean the bathtub 2. Now I can do it.

The present invention will be explained in detail below with reference to Examples.

As shown in Fig. 1, a fine bubble generating nozzle 1 that generates fine bubbles and a suction part 3 that sucks water in the bathtub 2 are installed above and below on the side wall of the bathtub 2. 3 through a circulation pipe 4 outside the bathtub 2. This circulation pipe 4 is equipped with an intake part 5 for sucking air from the suction part 3 side, a pressurizing pump 6, and an accumulator 7 for removing coarse air bubbles. A switching valve 8 is provided between the nozzle 1 and the nozzle 1. The switching valve 8 is a three-way valve, and may be a manual valve, a solenoid valve, or a ball valve. A jet nozzle 1 is attached to the upper part of the side wall of the bathtub 2, and the jet nozzle 1 and a switching valve 8 are communicated through a branch pipe 10. As shown in FIG.
The lower narrow diameter portion 11a of the suction pipe 11 is bent back below the jet nozzle 1 and connected to the jet nozzle 1 so as to be perpendicular to the jet nozzle 1. Narrow diameter portion 11 of suction pipe 11
A net storage part 13 is provided in the middle of the net a, and a floating object removing net 12 is stored in this net storage part 13. When the pressure pump 6 is driven and the switching valve 8 is switched so that water is sent to the fine bubble generating nozzle 1, the water in the bathtub 2 is sucked in from the suction part 3, and the air is The coarse air bubbles are removed by the accumulator 7,
Fine bubbles are ejected from the fine bubble generating nozzle 1 into the bathtub 2. Also, when the switching valve 8 is switched so that the flow flows to the branch pipe 10 side, the jet nozzle 9
Jet water is squirted out from the bathtub and can be used as a jet bath. At this time, water containing floating matter A on the water surface is sucked in from the upper end of the suction pipe 11 by the ejector action of the jet nozzle 9, and the floating matter A is collected by the floating matter removing net 12. So dirt,
Floating substances A such as limescale and hair are removed and the water in the bathtub 2 is maintained clean.

[Effects of the invention] As described above, the present invention provides a switching valve between the accumulator of the circulation pipe and the fine bubble generation nozzle, and communicates the jet nozzle provided in the bathtub with the switching valve through a branch pipe. The suction pipe that sucks floating matter on the water surface of the bathtub is connected to the jet nozzle so that suction by the ejector action of the jet nozzle works, and a floating matter removal net is placed in the middle of the suction pipe, so that water is supplied to the branch pipe. When the switching valve is switched to , jet water is ejected from the jet nozzle into the bathtub, and water containing floating matter on the water surface is sucked in from the suction pipe by the ejector action of the jet nozzle, and the floating matter is collected in the floating matter removal net. It can also be used as a jet bath, and can also clean the bathtub by removing floating matter such as limescale, grime, and hair.
