Abstract

PURPOSE:To exhaust a water flow with high pressure in which a bubble is mixed smoothly by a flexible pipeline loadable/unloadable on an exhaust pipe, a second air suction pipe provided at the outer periphery of the flexible pipeline, and a second mixer to mix the air from the second air suction pipe in water from the flexible pipeline at the most downstream terminal of the flexible pipeline. CONSTITUTION:The flow of water circulating in a circulation pipeline 12 with a pump 11 is accelerated with a nozzle part 24, and the air is inhaled from a first air suction pipeline 15 with negative pressure generated by the above acceleration, and the water is mixed in the air at a first mixer 13, then, the water flow including the bubble is generated. When no flexible pipeline 18 is connected to the exhaust pipe 17, the water including the bubble is exhausted from an exhaust port 16. Also, when the pipeline 18 is connected to the pipe 17 and the shutoff valve 14 of the air suction pipe 15 is closed and also, the second air suction pipe 19 is connected to a third air suction pipe 22, the air is mixed in the water with the second mixer 20, and a jet including the bubble can be obtained from the tip of the pipeline 18. At such a case, only the water flows in the pipeline 18, and low resistance exists in the pipeline 18.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a bubble jetting bathtub device that generates bubbles in a bathtub using water flow from a pump.

BACKGROUND OF THE INVENTION In recent years, as people become more health-oriented, an increasing number of people desire a more comfortable bubble jet bath at home.

Conventionally, this type of bubble jet bathtub device is disclosed in Utility Model Application Publication No. 1-1128.
The configuration shown in Publication No. 31 was common.

The configuration will be explained below with reference to FIG. 4.As shown in FIG. A water stream containing air bubbles is ejected from the side surface 5. The jet nozzle 6 is a flexible jet guide pipe 7.
A spouting device 8 having a can be detachably connected thereto. Note that 9 in the figure is an air suction pipe.

Problems to be Solved by the Invention In such a conventional bubble jet bathtub device, since a mixed water flow of water and air flows through the flexible jet guide pipe 7, the fluid resistance of the pipe increases and the jet nozzle 6 One problem was that a powerful water stream could not be obtained from the jet, and the pressure of the jet was greatly attenuated, making it almost impossible to obtain a pine surge effect. In addition, air bubbles coalesce into large bubbles in the flexible jet guide tube 7, causing water and air to flow alternately and eject, resulting in an intermittent flow that causes extremely discomfort. Challenges were arising.

SUMMARY OF THE INVENTION The present invention solves these conventional problems and aims to provide a bubble jetting bathtub device that smoothly jets out a high-pressure water stream mixed with air bubbles.

Means for Solving the Problems In order to achieve the above object, the present invention includes a circulation pipe that includes a pump and circulates water in a bathtub, and a pump that is provided in the middle of this circulation pipe and mixes air into the water. a first mixing device for
a first air suction pipe equipped with a shutoff valve that supplies air to the mixing device; and a jetting pipe that spouts a mixed water flow of water and air from the first mixing device; a flexible conduit, a second air suction pipe provided on the outer periphery of the flexible conduit, and air from the second air suction pipe provided at the most downstream end of the flexible conduit; This is a bubble spouting bathtub device including a second mixing device for mixing water from a flexible pipe.

Effect of the present invention With the above-described configuration, water and air are mixed at the tip of the flexible pipe, and a smooth flow of water without air is obtained in the flexible pipe, allowing the mixing of water and air at a comfortable pressure. This results in a water flow.

EXAMPLE Hereinafter, an example of the bubble jet bathtub device of the present invention will be described with reference to FIGS. 1 to 3.

As shown in the figure, a circulation pipe 12 equipped with a pump 11 for circulating water in the bathtub 10 is provided outside the wall surface of the bathtub 10. A first mixing device 13 for mixing air into water is provided in the middle of this circulation pipe 12, and this first mixing device 13 has a first air suction pipe 1 equipped with a shutoff valve 14 for supplying air.
5 is connected. Further, at the outlet of the first mixing device 13, a spout pipe 17 is provided with a first spout 16 for spouting a mixed water flow of water and air from the first mixing device 13.
has been established. A flexible conduit 18 is detachably connected to this ejection pipe 17. Furthermore, a second air suction pipe 19 is wrapped around the outer peripheral surface of the flexible pipe end 8, and air from the second air suction pipe 19 and the flexible pipe 19 are connected to the most downstream end of the flexible pipe 18. A second mixing device 20 is provided for mixing the water from the flexible conduit 18. In addition, the third air intake pipe 22
is fixed to the wall surface inside the bathtub 10 by a fixing base 23, and is detachably connected to the second air suction pipe 19.

Note that 2I is the second spout 9.25 is the bathtub water suction port.

To explain the operation of the bubble jet bathtub device having the above configuration, the flow of water circulating through the circulation pipe 12 by the pump 11 is accelerated by the constriction part of the nozzle part 24, and the negative pressure generated by the acceleration of this flow causes the first Air is sucked in through the air suction pipe 15, and water and air are mixed in the first mixing device I3 to generate a water stream containing air bubbles. If the flexible conduit 18 is not connected to the jet pipe 17, the jet port 1
From 6, you can squirt water containing air bubbles to massage your lower back. Next, if you want to apply water containing air bubbles to other parts of the body, such as the abdomen or shoulders, connect the flexible conduit 18 to the spout tube 1.
7 to close the shutoff valve 14 of the first air suction pipe 15, and to connect the second air suction pipe 19 and the third air suction pipe 22.
By connecting the flexible conduit 18, a jet flow containing air bubbles can be obtained from the tip of the flexible conduit 18. At this time, since air is mixed at the tip of the flexible conduit 18, only water flows inside the flexible conduit 18, compared to the conventional device in which air and water were mixed. The internal resistance is small, so a sufficiently strong jet can be obtained. Therefore, with this configuration, a comfortable pine surge can be obtained by applying the bubble jet to any part of the body.

Effects of the Invention As is clear from the above description of the embodiments, the bubble jetting bathtub device of the present invention not only allows the bubble water to be spouted into the bathtub, but also allows the use of flexible pipes when performing pine surge. The water and air are mixed only at the spout at the end of the flexible pipe, meaning no air is included in the flexible pipe, which reduces the increase in fluid resistance of the flexible pipe. You can get a powerful and comfortable jet of pressure without any pressure. The high-pressure mixed water stream containing air bubbles can be freely applied to any part of the body through the flexible pipe.
