Description

DETAILED DESCRIPTION OF THE INVENTION (A) +1' Field of Industrial Application The present invention relates to a bubble-generating bathtub in which the amount of ejection from the bathtub changes in an irregular wave shape.

(B) Conventional Technology Conventionally, as an example of a bubble-generating bathtub, a bath water circulation passage is interposed between the bathtub body and a circulation pump, and an air intake part is connected to the bath water circulation passage. The number of revolutions of the circulation pump is controlled by a control unit to adjust the amount of water mixed with air bubbles to be ejected into the main body of the m1 product. There is.

(c) Problems to be Solved by the Invention However, the conventional bubble-generating bathtub has been designed to reduce the amount of ejection from Sil.
However, since the amount of ejection does not change dynamically, the bather's body is only affected by the jet of strong strength, and the bather's body does not respond to the stimulation of the jet. There was an incongruity in that the bathers got used to the bubble bathing, the acupressure effect etc. of the jet stream was reduced, and the bathers got tired of bubble bathing.

In addition, when the jet stream is made stronger, the jet stream of the same strength hits the same part of the bather's body, causing pain and discomfort to the bather, making it difficult to bathe for a long time. .

To this end, we have developed a bubble-generating bathtub that can provide bathers with a jet stream that allows them to enjoy long bubble baths without getting tired, for example, a stream that allows them to fully enjoy the comfort of relaxing in the murmuring of a brook. was desired.

(2) Means for solving the problem Therefore, in the present invention, a bath circulation flow path is interposed between the bath 10 main body and the circulation pump, and an air intake part is connected to the bath circulation flow path, In the bubble-generating bath cypress that can blow out air bubbles into the bathtub body, the rotation speed of the above-mentioned exposed ring pump is controlled via the control unit, and the rotation speed of the gate ring pump is controlled. This is a bubble blowing method in which the ejection amount of a bath bath changes in a non-constant wave form with respect to time (6 Iff is 111 (j%)).

In addition, the bath water return flow path is composed of a bath water suction flow path and a bath water forced flow path, and the end of the bath water forced flow path is opened in the bath main body to form a spout nozzle. The air intake section is connected in communication with the bath water forced flow channel, and the amount of opening and closing of the above-mentioned jet nozzle can be controlled via the control section. glIIfflI function, a
Another feature is that the rotational speed of the one-ring pump, the opening/closing amount of the ejection nozzle, and the air intake amount of the air intake section are each changed in a non-constant wave shape with respect to time.

? E) Functions and Effects According to the present invention, the following functions and effects (1) are brought about.

In other words, since the rotation speed of the circulation pump can be changed in an irregular wave shape with respect to time, the amount of spouted bath water mixed with shellfish bubbles also changes in an irregular wave shape, and it is like the murmuring of a natural stream. It is possible to provide a soft jet stream with a hit close to that of water, and also to create a slow flow in stagnation, allowing bathers to enjoy the comfort of letting their body rest in the gentle, swaying stream. .

Furthermore, by changing the range of the rotational speed of the circulation pump, which is changed into an inconstant wave shape, into a high rotational speed region and a low rotational speed region, the jet strength can be changed.

Further, by controlling the opening/closing amount of the jet nozzle, the jet flow described above can be varied.

For example, by opening the jet nozzle almost fully, the amount of jet from the jet nozzle is basically large and the jet pressure is 0.
(It is possible to create a mild jet flow form, and by opening the jet nozzle slightly, the jet flow from the jet nozzle is small, and the jet pressure is high, resulting in a shiatsu-like jet form.) be able to.

In addition, by controlling the air intake amount of the air intake part,
The strength of the jet described above can be varied. In other words, by increasing the amount of air intake, you can increase the amount of air bubbles mixed into the jet stream, giving you a stronger experience than anyone else! In addition, by reducing the amount of dL bubbles during the jet stream by reducing the number of intake claws, it is possible to give the bather a weaker sensation.

In addition, the rotation speed of the circulation pump and the opening/closing amount of the jet nozzle,
By changing the air intake amount of the air intake part into a non-constant wave shape between II and 1, respectively, the air bubbles/1t
The jet volume and pressure of the Jiri bath, as well as the amount of mud bubbles, change into an irregular wave shape, and the jet flow resembles the murmuring of a stream.
In addition, it is possible to create a jet stream whose perceived strength increases over time, and the bather can enjoy the unexpected jet stream. Therefore, with this type of jet flow, the bather's body does not become stimulated by the jet flow, and the jet flow can provide acupressure-like, massage-like effects, etc., and the problem that the bathing sound becomes boring when taking a bubble bath is avoided. No cow.

In addition, the jet stream of the same strength is not continuously applied to the same part of the bather, which prevents the bather from feeling pain or discomfort, and allows the bather to take a comfortable bubble bath for a long time. Ru.

This will be explained below with reference to FIGS. 7 to 9. In addition, in this report, the jet flow shape caused by the change in the rotational speed of the bleaching ring pump (P) is referred to as "fluctuation blow".

FIG. 7 is an explanatory diagram showing the relationship between the rotation speed of the circulation pump (T') and time <1), where (Ql) is the circulation pump (L
)) shows the same rotation number change t+h line.

The lIi1 rotation speed change song 491 (Ql) changes the rotation speed of the ring pump (P) within a certain rotation speed range (for example, 1500 to 3000 r.p.
(within the range of s), the wave shape is changed to an inconstant wave shape with an inconstant amplitude.

However, the change in the shape of the unsteady wave is a sharp change that partially eclipses linearly or curved, and changes with rise, fall, and convergence within a certain period of time.

In addition, the jet strength of the fluctuating blow can be determined by setting the rotation speed range of the circulation pump (1'), which changes the wave shape to a non-constant wave shape, to a high rotational speed range (for example, 2000 to 3000 r.p.n+), or Also a (rotation speed range (e.g. 1500-250

In addition, the control unit (C) controls each jet nozzle (2) (3).
(4) It is also possible to control the change in the opening/closing amount, which changes into an irregular wave shape, so that the cedar state becomes a hole.

In addition, the control unit (C) controls the jet nozzles (2) (3) (
By controlling the opening/closing amount of 4) to be constant for a certain period of time,
It is possible to change the fluctuation blow.

For example, by leaving each jet nozzle (2), (3), and (4) in a substantially open state for a certain period of time (for example, 30 seconds), basically each jet nozzle (2), (3), and (4) It is possible to create a mild blow with a large amount of jet and a jet pressure of By doing so, basically each jet nozzle (2) (3) < 4)
Acupressure blow with a small amount of ejection and high ejection pressure can be achieved.

Moreover, FIG. 9 is an explanatory diagram showing the relationship between the opening/closing amount of each air bubble amount adjusting valve (50) (51) (52) provided in the air intake part (5) and time 0), and (Q3) shows the opening/closing m change curve of each bubble m control valve (50) (51H52).

In addition, the control unit (C) controls each bubble amount control valve (50) (
It is also possible to control so that the change form of the amount of opening/closing that changes to the constant wave shape is different for each of (51) and (52).

In addition, the rotation speed change curve (Q1) and the opening/closing amount change curves (Q2) (Q3) described above are based on the brain waves (for example, alpha waves) of the bath table.
Feminization of σ11 pressure, fuzzy 11 according to changes in pulse rate
It is also possible to provide a comfortable blow by controlling the l1 and the two.

In addition, we have created a lower stage that dynamically identifies the bather's body movements, crawling, body shape, etc., and a rotation speed change curve (Q1) and an opening/closing amount change curve (Q2) to adapt to the bath name. By fuzzy controlling (Q3), it is also possible to provide a smooth blow.

Moreover, FIG. 10 shows a bubble generating bath +f as another embodiment.
f(A) is shown, and the foot, dorsal, and ventral outgoing nozzles (

D) (+)) (D), and each suihuan pump (1') is connected to 1,
It can be controlled by a control section (C).

Therefore, in the bubble generating bath WJ(A), each jet nozzle (2), (3), and (4) has a different jet flow type (mild blow, acupressure blow, pulse blow, wave blow, cycle blow, program blow, and fluctuation blow). )
The bath can be squirted.

At this time, by varying the amount of opening and closing of each jet nozzle (2) (3) (4), each jet nozzle (2) (3)
(4) It is possible to emit a bath of fluctuating blow in a different form.

In addition, the rotation speed change curve (Q1
), by intersecting the spout etc., different types of baths can be sprayed from each spout nozzle (2), (3), and (4)! 1 can be avoided.

In this way, by changing the rotation speed of the circulation pump (P) into an irregular wave shape with respect to 0, the air bubbles ejected from the three output nozzles (2), (3), and (4) are gradually reduced. The ejection amount of bath water can also be changed into an irregular wave shape, and 1
It is possible to create a gentle flow similar to the babbling of a natural stream, and also to create a slow flow in a stagnation, and the sound of bathing is like the sound of a body in a gently swaying stream. You can enjoy the comfort of leaving everything to yourself.

In addition, the range in which the rotation speed of the circulation pump (P) is changed is
By being able to feed from a high rotational speed range to an Omega rotational speed range, the jet flow strength can be changed, so it can be widely adapted to the preferences of bathers.

Also, open and close each jet nozzle (2), (3), and (4) by 1.
By pressing 1, you can create a gentle blow with a stimulating massage effect as the water overflows.
It is also possible to perform a fluctuation blow in the form of a shiatsu blow, which basically has a shiatsu-like effect. .

In addition, each air bubble I1 control valve ('
．． By controlling the opening/closing amount to +0)(51)(52), the strength of the jet flow described above can be varied.

In other words, by increasing the amount of air intake, increasing the amount of bubbles generated in the jet flow will give the bather a stronger sensation.
．． In addition, by reducing the number of air intakes and reducing the amount of air bubbles mixed into the jet flow, it is possible to provide a weaker sensation to the bather.

In addition, the rotation speed of the Shaoan bomb (P) and each jet nozzle (2

The eruption, ejection pressure, and amount of popular bubbles change into a constant wave shape, giving the bather a jet flow similar to the babbling of a stream, but with a strong physical sensation. A changing jet stream! Bathers can enjoy the unexpected jet stream.

With this type of jet flow, the bather's body does not become accustomed to the stimulation of the jet flow, and the jet flow provides acupressure,
Massage-like effects can be ensured, and the problem of bathers getting bored with bubble bathing does not occur.

In addition, jets of the same strength do not continue to flow in the same place during bathing, preventing the bather from feeling pain or discomfort, and making long-term bubble baths more comfortable. I can do it.
