Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called jet bath jet supply device for jetting a jet flow into a liquid in a bathtub, and more specifically, to a jet bath from individual ejector nozzles provided on a side wall of the bathtub. The present invention relates to a jet flow supply device capable of supplying a jet flow over a wide range.

[0002]

2. Description of the Related Art As a conventional jet bath for jetting a jet into the liquid in a bath, an ejector nozzle is arranged on the side wall of the bath with its nozzle opening facing the bath, and the ejector nozzle is provided with a liquid supply passage. It is configured to be connected to an intake passage to blow a gas-liquid mixed jet from the nozzle opening into the liquid in the bath. In this type of jet bath, the main part of the bather is pressed by the liquid pressure of the gas-liquid mixed jet ejected from the ejector nozzle, and the pressure fluctuations caused by the bubbles in the gas-liquid mixed jet bursting in the liquid cause massage. Some are designed to have an effect.

[0003]

Conventionally, the ejector nozzle is fixed to the side wall of the bathtub, and since the range in which the jet flow can be supplied from this ejector nozzle is narrow, it is necessary to apply the jet flow to the main part desired by the bather. The person had to move his body to move the main part into the jet stream.

It is also conceivable to fix a large number of ejector nozzles on the side wall of the bathtub to blow out a jet flow over a wide range from all the ejector nozzles. However, in this case as well, since the range in which jets can be supplied from individual ejector nozzles is narrow, it is necessary to arrange a large number of ejector nozzles over the entire wide range to be blown out, and moreover, the jets from a large number of ejector nozzles Since a large amount of liquid must be supplied in order to blow out the water, there is a problem that it cannot be implemented at low cost.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems and provide a jet flow supply device capable of supplying a jet flow in a wide range from individual ejector nozzles into a bath.

A second aspect of the present invention is the same as the first aspect, wherein a rotary blade (30) is rotatably provided between the nozzle port (24) and the liquid supply passage (10), and the rotary blade (30) is provided with a support member ( S). It should be noted that the rotary vane may have a structure capable of transmitting the rotational force generated by receiving the hydraulic pressure to the support member, and may be interlocked with the support member via a gear device or a rotatable support shaft. Alternatively, it may be directly fixed and connected to the support member.

A third aspect of the present invention is the same as the first aspect, wherein the jet blowout direction (D) from the ejector nozzle (22) is set to the spindle (11).
It is formed by twisting around the shaft center (14).

Although the jet flow of the present invention may be composed of only liquid, a gas-liquid mixed jet may be jetted from the nozzle port of the ejector nozzle by connecting an intake passage or the like to the ejector nozzle. In this case, As a result of the bubbles in the gas-liquid mixed jet bursting in the liquid, pressure fluctuations occur and the massage effect can be further enhanced.

[0012]

In the present invention, the ejector nozzle is fixed to the support member, and the support member is rotatable about the axis of the support shaft. Therefore, the ejector nozzle rotates together with the support member while ejecting the jet flow. A swirling jet that rotates around the axis of the support shaft is formed in the bathtub.

At this time, when a rotary vane is provided between the nozzle port and the water supply passage and the rotary vane is connected to the support member, the rotary vane is rotated by the hydraulic pressure of the liquid flow supplied to the ejector nozzle. A force is generated, and the rotational force causes the support member to rotate.

[0049]

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

(1) Since the swirling jet flow rotating around the axis of the support shaft is blown out from the nozzle port of the ejector nozzle, the jet flow can be widely supplied from the individual ejector nozzles into the bath. As a result, only a small number of ejector nozzles need to be provided on the side wall of the bathtub, the amount of liquid supplied to all ejector nozzles can be reduced, and energy can be saved, and the cost can be reduced.

(2) Since the jet flow is supplied from the ejector nozzles into the bath over a wide range, the bather can hit the jet at a desired position without moving the body, and since the jet flow is swirling, the jet flow is generated. It will be applied intermittently to the position desired by the bather, and an effective massage can be performed as if manually massaged.

(3) In addition, when the jet stream is blown out in the absence of a bather, a jet stream is formed in the bathtub, which changes in the blowing direction with time, such as spirally swirling. The effect can be obtained.

(4) When a rotary blade is provided between the nozzle port and the liquid supply passage and this rotary blade is connected to the support member,
A rotary force is generated in the rotary blades by receiving the hydraulic pressure of the liquid flow supplied to the ejector nozzle, and the supporting member is rotated by this rotating force, so a drive source such as an electric motor is not required to rotate the supporting member, It can be implemented at low cost. Moreover, since the rotational force is generated by the pressure of the liquid flow, there is no danger of electric leakage, and the jet flow supply device for blowing hot water or the like can be safely configured.

(5) When the jet flow direction of the ejector nozzle is formed by twisting around the axis of the support shaft, the support member receives the reaction force due to the liquid pressure of the jet flow discharged from the nozzle port. Since it rotates around the axis of the shaft, no special member is required for rotationally driving the support member. As a result,
Since the device structure can be simplified, it can be implemented at low cost and maintenance can be performed easily.

(6) When the support shaft is rotatably supported by the main body of the apparatus, the support member is fixed to the tip of the support shaft, and the drive source is connected to the rear part of the support shaft, the drive source is controlled. By doing so, the rotation direction and rotation speed of the support member can be easily changed and set via the support shaft, so that the jet flow can be made into a swirling jet flow rich in changes. As a result, the massage can be applied more effectively and the visual effect can be enhanced.
