Description

TECHNICAL FIELD The present invention relates to a bathtub with a bubble generating device.

2. Description of the Related Art As shown in FIGS. 3 and 4, a conventional bathtub of this type has a structure in which hot water in the bathtub 1 is circulated to eject a bubble flow into the bathtub 1 from a jet port 3. This foam flow stimulates the body to promote blood circulation.

Problems to be Solved by the Invention In such a conventional configuration, since the bubble jet flow from the jet port 3 collides with the body to promote blood circulation, there is a problem in terms of added value. .

The present invention solves such a problem, and provides a bathtub in which the jet flow can be made to flow along the inner wall surface of the bathtub and the cleaning property is added.

Means for Solving the Problems In order to solve the above problems, a bathtub according to the present invention comprises a pump for circulating hot water in the bathtub, a suction port and a jet port provided on a wall surface of the bathtub, and a tip portion of the jet port having a recessed portion. A jet board that is held substantially at the center and attached to the wall surface of the bathtub is provided. The jet flow can be made to follow the curved surface so that the jet flow also follows the inner wall surface of the bathtub.

Action The bathtub of the present invention having the above-described configuration uses the property (Coanda effect) of the jet flow ejected along the wall surface to adhere to it even if the wall surface is curved so that the jet flow along the inner wall surface of the bathtub. In addition to the jet water flow that directly ejects into the bathtub, bubbles can also be generated from the bottom of the bathtub, and the water flow along the side wall of the bathtub can also remove dirt adhering to the wall surface. Is.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, reference numeral 4 denotes a bath, and a jet port 5 and a suction port 6 are attached to the inner wall of the bath. Spout 5
The suction port 6 is connected to a pump 8 via a pipe 7. An air pipe 9 is arranged at the ejection port 5. The jet port 5 is composed of a main body 10 and a jet board 11. A nozzle 12 and an air port 13 are formed in the main body 10, and the tip of the ejection port attached to the substantially central portion of the recess of the ejection plate 11 is made of a flexible material that holds the bent state. In 11, a curved surface is formed on the peripheral portion facing the pipe. The flexible pipe 14 thus formed is formed.

In the above structure, when the pump 8 is energized, the hot water in the bathtub 4 is swallowed from the suction port 6 and ejected from the ejection port 5.
At this time, air is taken in from the air port 13 to form a flow containing bubbles. By changing the direction of the flexible pipe 14, the jet flow from the jet port 5 can be changed in any direction. In particular, when jetting along the curved surface of the peripheral edge of the jet board 11 facing the flexible pipe 14, the property of adhering to the curved surface and flowing (Coanda effect) can be utilized, and a jet flow flowing along the wall surface of the bathtub can be created. It is also possible to use it to generate bubbles from the bottom surface, and it is also possible to clean the wall surface by the flow along the wall surface.

Although the flexible pipe 14 is shown as the freely movable mechanism in the above-mentioned embodiment, any structure can be used as long as it keeps the bent state, and the effect of the present invention can be achieved.

Effects of the Invention As is clear from the above description of the embodiments, the present invention has the following effects.

Since the jet flow can flow along the bottom of the bathtub, it can be used as a bubble generator from the bottom in addition to the jet jet.

Since the jet flow can flow along the side wall surface of the bathtub, the wall surface can be cleaned.

Of course, you can change the jet flow in any direction, so you can massage the jet jet at the position you want in the body in the bathtub.
