FIG. 1 is a perspective view of a bubble bathtub to which a control method for a bubble bathtub device according to an embodiment of the present invention is applied, FIG. 2 is a system diagram of the same bubble bathtub device, and FIG. 3 illustrates another embodiment method. FIG.

In FIG. 1, a bathtub 50 is equipped with a large number of bubble ejecting nozzles. In this example, a total of 18
A number of bubble ejecting nozzles are provided. Among these, bubble ejection nozzles 1 to 12 are provided on the side of the bathtub 50,
The bubble jetting nozzles 13 to 17 are provided on the bottom surface of the bathtub 50.

A side surface of the bathtub 50 is provided with an outlet 19 for extracting hot water from the bathtub 50 and circulating it. Further, a large number of human body detection sensors 20 are provided in the bathtub 50 so as to circulate around the side surface thereof.

Air intake piping 22 having an air flow rate adjusting valve 21 is connected to each of the bubble jetting nozzles 1 to 18.

The first-stage extraction port 19 is connected to a pump 25 (FIG. 2) via a pipe 23. The piping on the discharge side of the pump 25 branches into a total of 18 pipings 24, and each piping 24 is connected to the bubble jetting nozzles 1 to 18, respectively.

The detection signal of the human body detection sensor 20 is input to a control device 26 as shown in FIG. 2, and the control device 26 outputs a control signal to the air flow rate adjustment valve 21 and pump 25 of each nozzle 1 to 18. has been done.

In the bubble bathtub device configured in this way, when the operation switch 27 is operated to give an operation start signal to the control device 26, the pump 25 is started and hot water in the bathtub 50 flows through the outlet 19 and the piping 23, 24. The water is sent to each nozzle 1 to 18 through the air, and is ejected into the bathtub 50. At this time, each nozzle 1A-
Air is mixed into the water stream ejected from the nozzle according to the opening degree of the air flow rate adjustment valve 21 of 18, and is ejected into the bathtub 50 in the form of fine bubbles.

The human body detection sensor 20 detects the human body in the bathtub 50, and since a large number of human body detection sensors 20 are provided, it is possible to detect the position and posture of the human body in the bathtub 50. . In this embodiment, the opening degree of each air flow rate adjustment valve 21 is adjusted so that a large amount of air bubbles are ejected from the nozzle close to the human body in the bathtub 50. For example, when the human body is at symbol A in FIG. If you are bathing with your back to the short side of the bathtub shown and your feet thrown out to the other short side B facing this, nozzle 1.12.11.2.17.
18. A large amount of air bubbles are ejected from 1O toward the waist, torso, and chest of the human body. Also, nozzles 13.14.15.
From 16, a small amount of air bubbles are ejected towards the thrown foot. A small amount of air bubbles is ejected from the nozzle 3.4.5.6.7.8.9. Note that when the back of the bather in this bathing posture is located at the center of the short side A, the largest amount of bubbles will be ejected from the nozzle 12 among the three rows of nozzles 1, 12, and 11. . Furthermore, when the back of the human body is located toward the corner shown by C in FIG. 1, the largest amount of bubbles are ejected from the bubble ejection nozzles 1 and 2.

Similarly, a bather in the bathtub 50 places his or her back on the short side B,
If you are in a position where you throw your legs to the short side A, nozzle 4
．． A large amount of bubbles are ejected from nozzle 5.6.7.8 and 13.14, and a slightly smaller amount is ejected from nozzle 15.16.17.18. Other nozzles 1.
A small amount of bubbles will be ejected from 2.3.9.10.11.12.

When a bather in the bathtub 50 is located in the middle part of the bathtub 50 in the longitudinal direction, the nozzle 3.1 in the middle part in the longitudinal direction
The largest amount of bubbles is ejected from 5.16.9.

In this way, according to this embodiment, a large amount of bubbles are ejected from the nozzle close to the bather, so even if the overall amount of bubbles ejected from the bathtub 50 is the same, a large amount of bubbles can be efficiently ejected to the bather. can be applied, making it possible to give an efficient pine surge effect.

Note that the number of nozzles of the bubble bath device shown in FIG. 1, the number of human body detection sensors 20, and their installation positions are examples of the present invention. It is clear that the arrangement and number of detection sensors can be changed.

Further, in the above embodiment, the amount of bubbles is controlled by adjusting the opening degree of the air flow rate regulating valve 21, but the amount of bubbles may be controlled by adjusting the amount of hot water jetted from the nozzle.

FIG. 3 is a horizontal sectional view showing a bubble jetting nozzle according to another embodiment of the present invention.

In this embodiment, the bubble jetting nozzle 60 includes a nozzle body 61
and a holder 62 that holds the nozzle body 61. The holder 62 has a flange portion 63 on its front side, and the flange portion 63 is locked to the side wall surface 51 of the bathtub.

The nozzle body 61 has a spherical surface 64 on the rear end side, and a rack 66 is formed on the 0-spherical surface 64 that is in slidable contact with a concave spherical surface 65 formed on the holder 62. A supported pinion 67 meshes with the rack 66. Note that the pinion 67 can be rotated forward and backward by a motor (not shown).

The holder 62 is provided with a passage 68 for introducing hot water into the nozzle body 61 and a passage '69 for introducing air into the nozzle body 61. Hot water drawn from the bathtub is introduced into the flow path 68 via a pump, similar to that shown in FIG. 2, and the hot water is jetted into the nozzle body 61.

At this time, the air in the passage 69 is drawn into the nozzle body 61 due to the Venturi effect, and is ejected into the bathtub as fine bubbles.

The direction of the nozzle body 61 of the bubble ejection nozzle 60 is changed by a signal from a control device that detects the position of the human body in the bathtub, and the bubbles are ejected toward the human body in the bathtub.

Therefore, by using the bubble jetting nozzle 60 shown in FIG. 3 and controlling the direction of the nozzle body 61 by detecting the position of the human body in the bathtub, it is possible to efficiently apply a large amount of bubbles to the human body in the bathtub. It becomes possible.

In the embodiment shown in FIG. 3, the nozzle body 61 is configured to swing in the horizontal direction, but in the present invention, the nozzle body 61 may also be configured to swing in the vertical direction.

The present invention has a configuration in which a large amount of bubbles are ejected from a nozzle close to the human body as shown in Figure 1.2, and a third
The control method shown in the figure to direct the bubble ejection direction toward the human body may be combined.

[Effects] As described above, according to the control method for the bubble bathtub device of the present invention, a large amount of bubbles can be directed toward the human body in the bathtub, and the pine surge effect is high.

In addition, in the present invention, a large amount of air bubbles are not ejected into the bathtub unnecessarily (because efficient bubble bathing is possible, the capacity of the pump is reduced to reduce equipment costs and power costs). I can do it.

Furthermore, since a large amount of air bubbles are not ejected into the bathtub unnecessarily, the temperature of the water in the bathtub does not cool down easily.
