Description: TECHNICAL FIELD The present invention relates to a jet bath device that sucks hot water in a bathtub to eject a jet jet containing bubbles.

BACKGROUND ART Conventionally, a jet bath device of this type, which is designed to suck hot water in a bathtub and eject a jet jet containing bubbles, ejects hot water in the bathtub sucked from a suction port by pressurizing it with a circulation pump. In addition to being jetted from the mouth, the air sucked from the air suction port was supplied to the jet port, and the jet jet containing bubbles was jetted from the jet port. by the way,
In such a conventional example, there is a problem that a large massage effect cannot be obtained because the jet flow jetted from the jet port is always constant. Therefore, there has been provided an air adjusting means for intermittently controlling the supply of air with a solenoid valve. However, in such a conventional example, as shown in FIG. 10, since the intermittent pitch Tp and the supply amount of air are always constant, the problem that the massage effect is impaired due to acclimatization to stimulation was there. On the other hand, it is possible to manually interrupt the air as appropriate to avoid getting used to it, but in the case of interrupting for a long period of time or when changing instantaneously, the manual interrupting operation is troublesome. There was a problem.

[Object of the Invention] The present invention has been made in view of the above points, and it is an object of the present invention that there is almost no change in the strength of the jet jet action itself, and the bubble amount or bubble diameter of the jet jet is The subtle changes in stimuli caused by changes can prevent habituation to the human body's stimuli, so that a gentle and comfortable massage effect can be expected without giving a large shock or discomfort to the user, and the control action is automatic. It is an object of the present invention to provide a jet bath device which is easy to operate because it is carried out and which can withstand long-term use.

DISCLOSURE OF THE INVENTION (Structure) In the present invention, the hot water in the bathtub sucked from the suction port is pressurized by the circulation pump to be jetted from the jet port, and the air sucked from the air suction port is supplied to the jet port. In a jet bath device configured to eject a jet jet containing bubbles from an ejection port, an air adjusting unit which is inserted into an air supply path and intermittently controls the supply of air to the ejection port, and an intermittent pitch by the air adjusting unit. By providing the automatic control means for automatically changing the jet jet action itself, there is almost no change in the intensity of the jet jet action itself, and the subtle stimulus change caused by the change in the bubble amount or bubble diameter of the jet jet changes the human body. You can prevent habituation to the stimulus, so you do not give a big shock or discomfort to the user,
It is intended to provide a jet bath device which can be expected to have a gentle and comfortable massage effect, which can be easily operated because the control operation is automatically performed, and which can sufficiently withstand long-term use.

(Embodiment 1) FIGS. 1 to 4 show an embodiment of the present invention, in which hot water in a bath 1 sucked from a suction port 2 is pressurized by a circulation pump 3 and jetted from a jet port 4. In a jet bath device configured to supply the air sucked from the air suction port 5 to the jet port 4 and to jet a jet jet containing bubbles from the jet port 4, the jet bath device is inserted into the air supply path to the jet port 4. Provided are air adjusting means 6 including an electromagnetic valve 6a for adjusting the air supply, and automatic control means 7 formed by using a personal computer for controlling the air adjusting means 6 to automatically change the air supply. It is a thing. Here, in the embodiment, the air adjusting means 6 controls the supply of the air intermittently, and the automatic control means 7 can randomly select the intermittent pitch or the sine wave. I have to. The solenoid valve 6a is controlled by a solenoid to intermittently supply air.

The operation of the embodiment will be described below. FIG. 4 is a flow chart showing the control operation of the automatic control means 7. When "1" is inputted as the selection input Z, a random number R is generated and the solenoid valve 6a is operated during R (mS). Open to supply air and generate a random number R'to generate R '(m
During S), the solenoid valve 6a is closed to stop the air supply, and as shown in FIG. 3 (a), the intermittent pitch Tp of the air supply is randomly changed.

On the other hand, when "2" is input as the selection input Z, the opening / closing time X (= 500 | sin (πI / J) |) of the solenoid valve 6 is calculated based on the input division number J of π. , Solenoid valve 6a is opened during X (mS), and solenoid valve 6a is closed during X (mS), as shown in FIG.
It is designed to change Tp (= 2X) based on a sine wave.

As described above, in the above embodiment, the automatic control means 7 changes the air supply randomly or in a sinusoidal manner to automatically change the massage effect. It is less likely to occur and the massage effect will not be impaired by habituation. In addition, the jet jet can be interrupted automatically according to a predetermined interruption pattern by setting the selection input Z that selects the change state (sinusoidal change, random change, etc.), so the operation is easy. It is possible to realize a new jet bath device.

(Embodiment 2) FIG. 5 shows a control operation of another embodiment, in which one of the air supply period Ton and the air non-supply period Toff is made constant and the other is changed. FIG. 5 (a) shows a case where the supply period Ton is constant, and FIG. 5 (b) shows a case where the non-supply period Toff is constant. FIG. 6 is a flow chart showing the operation. First, the closing time Y of the solenoid valve 6a is set, the opening time X of the solenoid valve 6a is calculated as in the first embodiment, and the solenoid valve 6a is calculated by X and Y. It is designed to open and close in a sine wave.

Now, as in the present embodiment, by making one of the supply period T on or the non-supply period T off constant and changing the other, a large change can be felt, and the massage effect can be obtained without accustoming. Can be increased. Further, in the embodiment in which both the supply period Ton and the non-supply period Toff are changed, there is a feeling of strangeness due to overlapping changes, but in the present embodiment, since there is a single change, it is possible to reduce the feeling of strangeness. it can.

(Embodiment 3) FIGS. 7 to 9 show still another embodiment.
The air adjusting means 6 is configured to intermittently supply air and control the supply amount. In the embodiment, the air adjusting means 6 is provided with a supercharging pump 6b to reduce the air supply amount. We are free to increase by time.

Now, in the present embodiment, the supercharging pump 6b provided in the air adjusting means 6 is operated for a short time, and as shown in FIG.
The massage effect is increased by ejecting a jet jet having a strong pressure of P from the jet port 4. In this case, since the jet jet having a strong pressure jetted from the jet port 4 is jetted for a short time, a large ΔP is set, and a jetting force of a strong pressure that makes it uncomfortable to jet continuously is set. Even if a jet jet is ejected, a comfortable massage effect can be obtained, and a powerful massage effect that cannot be obtained by natural aspiration will be obtained.

[Advantages of the Invention] As described above, the present invention pressurizes the hot water in the bathtub sucked from the suction port with the circulation pump to jet it from the jet port, and supplies the air sucked from the air suction port to the jet port. In a jet bath device configured to eject a jet jet containing bubbles from an injection port, an air adjusting unit that is inserted into an air supply path and controls the intermittent supply of air to the injection port, and an intermittent pitch by the air adjusting unit. Is provided with an automatic control means for automatically changing the air supply, and since the air supply is automatically changed by the automatic control means, there is almost no change in the strength of the jet jet action itself, and The subtle changes in the stimulus caused by changes in the bubble volume or bubble diameter in the jet stream can prevent the human body from becoming accustomed to the stimulus, resulting in a large impact on the user. It is possible to expect a gentle and comfortable massage effect without giving a feeling of strangeness, and the control operation is automatically performed, so that the operation is easy and, further, there is an effect that it can endure long-term use.
