JP2002209967A - Shoulder patting device by jetting water in bathtub - Google Patents

Abstract

PROBLEM TO BE SOLVED: To pat the shoulders as if a person pat the shoulders by adjusting the jetting water by itself in bathing. SOLUTION: This shoulder patting device by jetting water in a bathtub is so formed that high-pressure water jet solenoid valve devices are arranged in a bathtub at prescribed intervals, jet air is alternately supplied, and strong- pressure jet hot water is mixed with the air and left/right alternately jetted so as to pat the shoulders.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention has an object to generate high pressure jet hot water in a bathtub by using jet air to perform shoulder tapping.

[0002]

2. Description of the Related Art Conventionally, hot water is dropped from a high place in a hot spring,
Devices for performing shoulder tapping by the drop pressure are well known.

[0003]

The above-mentioned prior art merely utilizes the drop pressure of hot water, cannot adjust the pressure, and alternately taps the shoulders like an actual shoulder tap. There was a problem that it could not be done.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and provide a high-pressure water injection solenoid valve device at a predetermined interval in a bathtub to supply jet air alternately.
It is characterized by mixing with air and jetting left and right alternately with high pressure jet hot water to perform shoulder tapping.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described in detail with reference to the illustrated embodiments. A bathtub 1 has a left jet jet nozzle 3 and a right jet jet nozzle 4 arranged on a part of an inner wall 2 thereof. Reference numerals 5 and 6 denote solenoid valves for air, which intermittently flow air at intervals of about one second. 7 is a circuit relay, 1
Reference numeral 6 denotes a dial for adjusting the time. Reference numeral 8 denotes an air switch which can be turned on and off in the bathtub. Reference numerals 9 and 10 denote electric circuits for opening and closing the solenoid valve from the relay. 11 is a push button, 12 is a high pressure pump (10Kg / cm2) 1 horsepower,
13 is a motor. 14 and 15 are solenoid valves for air 5,
6 is an air inlet.

Next, the operation will be described. The bather adjusts the circuit relay in advance. The circuit relay 7 is used for opening and closing the air solenoid valves 5 and 6 for introducing and stopping air attached to the air inlets 14 and 15 of the jet. The circuit relay 7 is provided with a time adjustment dial 16 on the upper portion. By turning the time adjustment dial 16, the opening and closing time can be adjusted from 0.1 second to 1 minute.
In the case of the present invention, about one second intervals are suitable for shoulder tapping. As for the adjustment of the number of times of opening and closing the switch, it was found that the interval of one second is better as a result of research. 0.8-1.
Two second intervals are also effective.

The principle of the jet utilizes the principle that the dynamic pressure is lower than the static pressure (the principle of spraying). When high-pressure water is produced by a pump and injected from a nozzle (about 3 mm in inner diameter), the pressure coming out of the nozzle is reduced, so that air enters from the air inlets 14 and 15 and becomes a powerful jet. This strength is the strength of a person. Also, this jet is air inlet 1
The air valves 4, 6 are attached to the valves 4, 15 to open and close, so that the tons alternate. Further, by alternately performing this action left and right, the shoulders are tapped.
The time is adjusted by the time adjustment dial 16 and the intensity is adjusted by adjusting the amount of flowing water. During bathing, when the push button 11 is turned on, the pump operates to start hot water supply. The air solenoid valves 5 and 6 are alternately operated, and the air enters and the jet rapidly increases. When the air solenoid valves 5 and 6 are closed, the jet becomes only water and becomes weak at all. This repetition makes it feel as if a person alternates his shoulders. The operation stops when the push button 11 is pressed.

[0008]

According to the present invention, a high pressure water injection solenoid valve device is disposed at a predetermined interval in a bathtub, jet air is supplied alternately, mixed with air, and jetted alternately left and right with high pressure jet hot water. Since the stroking is performed, it is possible for the person to actually tap the shoulders alternately.
