Abstract

PURPOSE:To improve the massage effect by providing control valves on air branch feed paths to multiple jet devices respectively, and changing the openings of the multiple control valves with the passage of time so that the openings of the control valves connected to adjacent jet devices differ from each other. CONSTITUTION:Control valves 6a-6d are provided on air branch feed paths 5a-5d to multiple jet devices 2a-2d. The openings of the multiple control valves 6a-6d are changed with the passage of time so that the openings of the control valves 6a-6d connected to adjacent jet devices 2a-2d differ from each other. The bubble quantity at a specific position is changed with the passage of time, bubble waves are formed in a bathtub, and a massage with smooth and proper stimulation can be given to the whole body of a bathing person. The massage effect is improved.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an air-blowing bathtub that blows out air bubbles from the bottom of the bathtub to impart a pine surge effect to bathers, and is particularly aimed at improving the pine surge effect. It is.

(Conventional technology) Conventionally, multiple air diffusers and nozzles were installed at the bottom of the bathtub, air was pumped to the air diffusers and nozzles, and fine air bubbles were ejected from the air diffusers and nozzles into the bath water. Air-blown bathtubs are known. This known air blow
As shown in Japanese Utility Model Application Publication No. 63-16035, there are bathtubs in which air bubbles are ejected from a diffuser plate at a desired position, and there are other bathtubs in which the amount of air bubbles can be controlled.

(Problem to be Solved by the Invention) In the former conventional example, the bather can receive air bubbles at any location, and the pine surge effect due to local stimulation is large, but the bather can sequentially change the locations where the air bubbles are received throughout the body. The changing operation to do so is troublesome, and it is not possible to easily impart an effective pine surge effect to the entire body. In addition, in the conventional case of the operator, the amount of bubbles is varied, and therefore the stimulus received by the body becomes stronger compared to when the amount of bubbles is fixed, but since the change is relatively monotonous, It is not possible to enhance the pine surge effect to that extent.

(Means for Solving the Problems) The present invention aims to solve the problems of the conventional example described above, and for this purpose, in the present invention, air is supplied via an air pump to a plurality of blowing devices provided at the bottom of the bathtub. By doing so, in an air-blowing bathtub formed by discharging air bubbles from the blower device, a control valve is interposed in each of the air branch supply paths leading to the plurality of blower devices, and the valve opening of the plurality of control valves is controlled. The configuration includes a controller that changes the opening degree over time to be different from the opening degree of a control valve connected to an adjacent blower device.

(Function) According to the above configuration, the amount of air bubbles from the plurality of II air devices changes over time, so that each part of the bather receives air bubbles of different strengths and weaknesses over time, and the bather receives air bubbles of different strengths over time. The part of the body that receives the bubbles will move over time.

(Example) FIG. 1 is an overall configuration diagram showing an example of the present invention, and FIG. 2 is an explanatory diagram showing changes in the amount of bubbles over time in the same example. Figure 3 shows the main sector famine circuit area for the same example.

In the first section, 1 is a bathtub, and 2a to 2d are blower devices attached to multiple locations on the bottom wall of the bathtub 1.

The blower devices 28 to 2d are connected to the air pump 3 via the supply path 4 and branch supply paths 58 to 5d, and each branch supply path 5a to 5d has a control valve 68 to 6d using a ball valve, respectively.
There is no intervention. The control valves 68 to 6d are controlled by a drive device @
Due to the rotation of the servo motors 7a to 7d, which will be described later, large
It is controlled in four stages: medium, small, and micro. Reference numeral 8 indicates an operating device provided in the bathroom, and 9 indicates a controller that drives and stops the air pump 3 and drives the drive devices 78 to 7d based on the operation of the operating device 8.

The controller 9 outputs a signal as shown below to the drive devices 78 to 7d when the operation device 8 is operated to start operation, and stops outputting the signal when the operation is stopped.

As shown in FIG. 3, the drive devices 73 to 7d output an opening detection means 71 using a servomotor 70 and a potentiometer, and opening setting signals corresponding to large, medium, small, and minute valve openings. An opening setting means 72, a comparing means 73 that compares the output of the opening detecting means 71 and the output of the opening setting means 72, and a matching output of the comparing means 73 causes the servo motor 70 to be stopped and the servo motor 70 to be stopped in other cases. It has paper means 74 for rotating the motor 70 forward or reverse. and controller 9
outputs an opening setting signal to the opening setting means 72 of the drive units 7a to 7d during operation, and changes the opening setting signal output to any opening setting means 72 from large to medium to small as time passes. → small → large, and a signal of a specific opening degree is outputted to the opening degree setting means 72 of the driving devices 7a to 7d of the adjacent blower devices 28 to 2d as time passes.

In the above configuration, the controller 9 is activated by the operation start operation of the operator 8, and after 7 hours have passed from the start of operation, the opening degree of the control valve 6a connected to the air device 2a is large, and the opening degree of the control valve connected to the blow device 2b is large. The opening degree of the control valve 6b is medium, and the opening degree of the control valve 6C connected to the blower device @2c is medium, and the opening degree of the control valve 6c connected to the blower device @2c is medium.
The degree of opening d becomes very small, and the amount of bubbles becomes maximum at the back end of the bathtub 1 and minimum at the full use end, as shown in FIG. 2(a).

After a further 2×T time has elapsed, the maximum amount of bubbles moves to the leg side as shown in Figure 2 (B), and after a further 3XT time, the maximum amount of bubbles moves further to the leg side as shown in Figure 2 (C). Moving to the image side, after 4 x T time elapses, the maximum amount of bubbles becomes the shoulder side end as shown in Fig. 2 (d), and after 5 x T time elapses, the state returns to the state shown in Fig. 2 (a). . Also, as you can see from the second section, the amount of bubbles at a specific location is thick → small → no＼ → medium →
It changes depending on the size and the passage of time.

(Effects of the Invention) As is clear from the description of the embodiments above, according to the present invention, the amount of bubbles at a specific location changes over time, and the fumarole location that spouts a specific amount of bubbles changes over time. Since it moves as the bath progresses, it looks like waves of air bubbles are formed in the bathtub, providing gentle and moderate stimulation to the entire body of the bather, and the operation is automated and easy to perform.
