Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jet bath for forming a jet flow in a bath liquid in a bathtub, and more specifically, it ejects the supply liquid into the bathtub from a plurality of ejector nozzles provided on the floor of the bathtub. The present invention relates to a jet bath adapted to form a rising jet.

[0002]

2. Description of the Related Art In a conventional jet bath, an ejector nozzle is arranged on a lateral side wall of a bathtub with its nozzle opening facing the inside of the bathtub, and a liquid supply passage and an intake passage are connected to this ejector nozzle, There is a configuration in which a supply liquid containing bubbles is blown out from a mouth to form a jet flow and the gas-liquid mixed jet is applied to a main part such as the back or waist of a bather. Then, the liquid pressure of the gas-liquid mixed jet presses the main part of the bather, and the massage effect is provided by the pressure fluctuation caused by the bubbles in the gas-liquid mixed jet bursting in the liquid.

[0003]

In the above-mentioned conventional jet bath, when the bather leaves the nozzle mouth, the bath liquid entering between them becomes a resistance, and the liquid pressure of the jet stream reaching the main part of the bather is reduced. Therefore, there is a problem that the massage effect is significantly reduced. Therefore, in the conventional jet bath, since it is necessary to enhance the massage effect, a nozzle port of an ejector nozzle is provided on the lateral side wall of the jet bath that is easily approached by the bather, and generally a jet flow in a substantially horizontal direction is formed from the nozzle port. Is configured. In addition, the liquid pressure of the jet is generally weak, and the spacing between the ejector nozzles is wide,
Nothing caused the bather to float in the bath liquid due to the jet fluid pressure.

The present invention provides a jet bath which allows a bather to float in the bath liquid due to the fluid pressure of a jet formed by ejecting a supply liquid from an ejector nozzle, and to massage the body of the bather in a free state not restricted by the floor or side walls. The purpose is to provide.

[0005]

In order to achieve the above object, the present invention is characterized in that a jet supply device is configured as follows, as shown in FIGS. 1 and 2, for example.

That is, an ejector nozzle is provided on the side wall of the bathtub (1).
(8) is arranged with its nozzle mouth (9) facing the bathtub (1), and the liquid supply passage (10) is connected to this ejector nozzle (8),
The supply liquid is blown out from the nozzle mouth (9) and jetted into the bathtub (1).
In a jet bath configured to form (M),
A large number of the above ejector nozzles (8) are arranged on the floor surface (7) of the bathtub (1) with a narrow spacing, and the liquid level in the bathtub (1) is extended from the nozzle opening (9) of each ejector nozzle (8). The feature is that a large amount of jet (M) rising toward (2) is formed so that the body of the bather (P) can float.

In this case, each ejector nozzle has only to form a jet flow that rises toward the liquid level in the bathtub. Therefore, the floor surface provided with the ejector nozzle is not only horizontal but inclined. May be. Although the jet flow may be composed of only liquid, a gas-liquid mixed jet flow may be formed by connecting an intake passage or the like to the ejector nozzle and mixing bubbles in the supply liquid blown out from the nozzle port of the ejector nozzle. Of course, in this case, the bubbles in the gas-liquid mixed jet burst and burst in the liquid to cause pressure fluctuation, and the massage effect can be further enhanced.

The flow rate of the jets ejected from the ejector nozzles is preferably 250 liters per minute or more in order to float the body of the bather, and about 400 liters per minute makes it possible to obtain an appropriate floating sensation and is more desirable. . Also,
The closer the ejector nozzles are arranged to each other, the easier it is for the bather to float, and it is desirable that the distance is 30 cm or less in order to float the bather's body in a well-balanced manner.

[0009]

[Function] Since a large number of ejector nozzles are arranged on the floor surface of the bathtub and a large amount of jet flow rising from each ejector nozzle toward the liquid surface in the bathtub is formed, a large amount of water ejecting from the floor surface in the bathtub is formed. An upflow of is formed. The bather is pushed upwards by this upward flow, and due to the hydraulic pressure of this upward flow and the buoyancy of the bath liquid, it is suspended in the bath liquid
The upward flow is received on the lower surface side of the body, and the essential parts are effectively massaged.

When the interval between the ejector nozzles arranged below the upper half of the bather's body is narrower than the interval between the ejector nozzles arranged in other parts,
The lighter lower half of the body floats in the upward flow from the portion with a wide spacing, while the heavier upper body of the bather floats in the upward flow from the portion with the narrow spacing.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show an embodiment of the present invention, FIG. 1 is a vertical side view of a jet bath, and FIG. 2 is a plan view.

As shown in FIGS. 1 and 2, the jet bath (J) has a plurality of partition walls (3) below the liquid level (2) in the bath (1).
A plurality of bathing parts (4) are provided side by side, and each bathing part
The bather (P) who bathes in (4) places his head on the pillow plate (5) and lays his body down with his limbs extended. Reference numeral (6) indicates a handle that the bather (P) grasps when moving the body.

An ejector nozzle (8) is arranged on the floor surface (7) of the bathtub (1) with its nozzle opening (9) facing the inside of the bathtub (1). Liquid supply channel (10)
And the intake passage (11) are connected to each other, and the supply liquid containing bubbles is blown out from the nozzle port (9) to form a gas-liquid mixed jet (M) in the bath (1).

That is, the liquid supply passage (10) is connected to each ejector nozzle (8) through the hot water supply pipe (13), and the liquid supply pump (12) is arranged in the liquid supply passage (10). Then, using the hot water discharged from the bathtub (1) as the supply liquid, the hot water supply pipe from the liquid supply passage (10)
It is constructed so as to be circulated by pressure-feeding to the ejector nozzle (8) at a predetermined pressure via (13).

At this time, since the intake passage (11) is connected to each ejector nozzle (8), air is sucked from the intake passage (11) at the flow velocity of the hot water flowing in the ejector nozzle (8), It is mixed with hot water in the ejector nozzle (8). As a result, the supply liquid containing bubbles is blown out from the nozzle opening (9), and a large amount of gas-liquid mixed jet flow that rises toward the liquid surface (2).
Since (M) is formed, a large amount of ascending flow that rises from the floor surface (7) is formed in the bathtub (1).

The ejector nozzles (8) are arranged in two rows in the front-back direction, below the upper body of the bather (P),
Six pieces are arranged below the lower body. Among these ejector nozzles (8), the ejector nozzles (8b) arranged below the lower body of the bather (P) have an arrangement interval of 15 to 20 cm, but the ejector nozzles arranged below the upper body of the bather (P). (8a) is arranged at a narrow interval of about 10 cm.

By driving the liquid feed pump (12), the supply liquid containing bubbles of about 400 liters per minute is blown out from each ejector nozzle (8), and the gas-liquid mixed jet (M) is jetted.
Is formed. The body pressure of the bather (P) is pushed upward by the rising liquid pressure of the gas-liquid mixed jet (M), and the bather (P) is moved by the liquid pressure of the gas-liquid mixed jet (M) and the buoyancy of the bath liquid. ) Will float near the liquid surface (2) in the bath liquid. As a result, the bather (P) floats his / her body and receives the pressure force due to the hydraulic pressure of the gas-liquid mixed jet (M) and the pressure fluctuation due to the burst of bubbles in a free state where the bather (P) is not restrained by the floor or the side wall, effectively Get massaged.

The ejector nozzle according to the present invention may form a jet flow composed of only liquid, but as in the above embodiment, the ejector nozzle is connected to the intake passage to form a gas-liquid mixed jet flow. Then, the bubbles in the gas-liquid mixed jet burst and burst in the liquid, causing pressure fluctuations.
You can massage bathers more effectively.

[0019]

Since the present invention is constructed and operates as described above, it has the following effects.

(B) Since a large amount of upward flow that rises up from the floor surface is formed in the bathtub and the bather becomes suspended in the bath liquid, the bather's body is suspended in the bath liquid and It is possible to perform massage by the gas-liquid mixed jet in a free state where it is not restricted by the side wall.

(B) Since a large amount of upward flow formed in the bath creates a floating state, the bather can take a bath while enjoying this floating feeling.

(C) Since a large amount of ascending flow rising from the floor is formed in the bathtub, a visual effect which has never been obtained can be obtained.

(D) In general, the body of a bather is heavier in the upper body than in the lower body. Therefore, the interval between the ejector nozzles arranged below the upper body side of the bather should be
When the interval between the ejector nozzles arranged in other parts is narrower than the interval between the ejector nozzles, the heavier upper body of the bather can be suspended by the ascending flow from the part with the narrow interval. As a result, the total number of ejector nozzles arranged on the entire floor surface can be reduced and the bather can be floated. Therefore, the total flow rate of the supply liquid pressure-fed by the liquid supply pump can be reduced to a low cost. .
