Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a bubble generating bathtub in which the amount of bathwater spouts changes periodically.

(B) Conventional technology Conventionally, as an embodiment of a bubble generating bath, a bath hot water circulation channel is interposed between a bathtub body and a circulation pump, and an air intake unit is connected to the bath hot water circulation channel. In some cases, hot water mixed with air bubbles can be ejected into the bathtub body, and the number of rotations of the hot water mixed with air bubbles can be adjusted by controlling the rotation speed of a circulation pump by a control unit.

(C) Problems to be Solved by the Invention However, although the above-mentioned bubble generation bathtub can adjust the amount of squirting, the amount of squirting does not automatically change. Simply hitting the jet with a monotonous intensity, the bather's body becomes a stimulus for the jet, and the acupressure effect of the jet is reduced, and the bather gets tired of bathing with air bubbles.

In addition, when the jet is strengthened, the jet having the same strength hits the same part of the body of the bather, so that the bather feels pain and discomfort and cannot bathe for a long time.

(D) Means for Solving the Problems Therefore, in the present invention, a plurality of bath water circulation passages provided with a circulation pump are connected to the bathtub body, and an air intake unit is connected to each bath water circulation passage. When connected, the bath water mixed with air bubbles can be spouted into the bathtub main body from a plurality of locations, and the rotation speed of each circulation pump can be controlled via the control unit. The present invention provides a bubble-generating bathtub in which the amount of bathwater spouted periodically changes.

(E) Function and Effect According to the present invention, the following function and effect are produced.

That is, since the number of rotations of the plurality of circulation pumps can be changed periodically with different phases, the amount of the bath water mixed with bubbles to be sprayed into the bathtub body from a plurality of locations is also increased. Periodic changes with different phases can be given to the bather, and a jet of the image of the returning wave can be given to the bather.Wave-shaped jets with different phases interfere with each other in the bathtub body and increase the amplitude. , Or reduce it to form a new interference wave, and the bather can enjoy the comfort of leaving the body in the gently fluctuating interference wave.

In addition, in such a jet that changes periodically, the bather's body does not become a stimulus to the jet, and the acupressure and massage effects of the jet can be ensured. The problem of getting tired does not occur.

In addition, a jet of the same strength does not continuously hit the same part of the bather's body, so that the bather can be prevented from feeling pain and discomfort, and a long-time bubble bath can be comfortably performed. .

(51) By adjusting the opening / closing amount of (52), the amount of air bubbles mixed in the bath water spouted from the foot side, back side, and ventral side jet nozzles (2), (3), (4) can be adjusted. .

The specific structures of the operation panel section (6) and the remote controller (30) are the same as those described in Japanese Patent Application No. 1-73367.

Further, in the present embodiment, each of the ejection nozzles (P), (P), and (P), which are respectively connected to the foot-side, back-side, and ventral-side ejection nozzles (2), (3), and (4), are connected to the inverter (I).
(I) The control unit (C) can be controlled via (I) so that the following program wave blow can be adopted in addition to the wave blow described in Japanese Patent Application No. 1-73367.

That is, in the program wave blow, the rotation speed of the circulation pump (P) is programmed in advance in the memory (m) of the control unit (C) for the time (t) as shown in FIGS. 7 to 14. It can be obtained by changing according to the function.

FIG. 7 is an explanatory diagram showing the relationship between the rotation speed of the circulation pump (P) and time (t), and (Q) shows a rotation speed change curve of the circulation pump (P).

Then, the rotation speed change curve (Q) is represented by a circulation pump (P).
The rotation speed of the motor is set to a constant period (for example, one minute) in a sine function with respect to time (t) and within a certain rotation speed range (for example,
(Within the range of 00 to 3000 rpm).

Further, the cycle of the rotation speed change curve (Q) may be indefinite. For example, the cycle is 1 minute, 2 minutes, 1 minute,
It can be changed irregularly, such as 3 minutes ... or 10 seconds, 20 seconds, 10 seconds, 30 seconds.

 The amplitude can also be changed and adjusted.

The period and the amplitude can be changed according to a program preset in the memory (m) of the control unit (C).

In this way, by changing the rotation speed of the circulation pump (P) in a sinusoidal manner with respect to the time (t), the air bubbles mixed from the ejection nozzles (2), (3), and (4) are mixed. The amount of hot water spouting can also be changed periodically in a sinusoidal fashion, giving the bather a realistic jet of the image of the returning wave, and the bather can easily immerse in the wave that gently fluctuates. You can enjoy the comfort of leaving your body.

In addition, by changing the rotation speed of the circulation pump (P) at an indefinite period, it is possible to provide an unexpected jet to a bather, and to give a jet of a wave image realistically.

Therefore, in such a jet form, the bather's body does not become the stimulus of the jet, and the acupressure, massage effect, etc. by the jet can be secured, and the bather gets tired of the bubble bathing. Does not occur.

In addition, a jet of the same strength does not continuously hit the same part of the bather's body, so that the bather can be prevented from feeling pain and discomfort, and a long-time bubble bath can be comfortably performed. .

Further, the rotation speed change curve (Q) shown in FIG. 8 changes the rotation speed of the circulation pump (P) gently upward in a curve with respect to time (t).

The rotation speed change curve (Q) is generated for a certain time (for example,
Within a certain range (for example, 1500 to 3000 r.
pm), and can be formed by gently changing it.

Further, the rotation speed change curve (Q) shown in FIG. 9 changes the rotation speed of the circulation pump (P) gently downward in a curve with respect to time (t).

The rotation speed change curve (Q) is generated for a certain time (for example,
Within a certain range (for example, 1500 to 3000 r.
pm), and can be formed by gently changing it.

As described above, since the number of revolutions of the circulation pump (P) can be changed in time in a curve that is upwardly convex or downwardly convex, the bather can change the spouting amount over time. While not being able to enjoy the bath, the bather's body becomes a stimulus for the jet, and the bather does not get tired of bathing with air bubbles.

In addition, since the jet of the same strength does not continuously hit the same place on the bather's body and the change in the jet volume is gentle, it does not give the bather pain or discomfort, Even when the bather is a child, an elderly person, or the like, there is no risk of danger to the body.

The rotation speed change curve (Q) shown in FIG. 10 changes the rotation speed of the circulation pump (P) in a wave-like manner with respect to time (t), and also makes the amplitude and cycle irregular.

Further, in the rotation speed change curve (Q), only the amplitude can be irregular.

In this manner, by making the amplitude and period of the rotation speed change curve (Q) or only the amplitude irregular, the jets from the jet nozzles (2), (3), and (4) can be made to approximate natural waves. It can give bathers the gentle and smooth comfort of natural waves.

Further, the rotation speed change curve (Q) shown in FIG. 11 changes the rotation speed of the circulation pump (P) in a wave-like manner with respect to time (t) and linearly changes the rotation speed.

In this way, by changing the rotation speed of the circulation pump (P) linearly, the ejection amount is linearly changed to a gradually increasing or decreasing state for a certain period of time, or constant without changing. Thus, a stimulating jet can be obtained.

Therefore, the bather can be provided with a jet of the image of the returning wave to the bather, and since the wavy jet changes in a complicated manner with a different stimulus over time, the bather surprisingly changes the stimulus. It is possible to enjoy the sexual feeling and to get a squeezing massage feeling, preventing the bather's body from getting accustomed to the pattern of change in irritability and getting tired of bubble bathing. it can.

In addition, a jet of the same strength does not continuously hit the same part of the bather's body for a long time, so that the bather can be prevented from feeling pain and discomfort, and bathing for a long time is comfortable Can be done.

The rotation speed change curve (Q) shown in FIG. 12 changes the rotation speed of the circulating pump (P) in a wave-like manner with respect to time (t) and partially or linearly changes the rotation speed. Is changing.

As described above, by partially or linearly changing the rotation speed of the circulation pump (P), the ejection amount is linearly changed to a gradually increasing or gradually decreasing state for a certain period of time. Alternatively, it can be made constant without changing, and it can be a stimulating jet, and the amount of jetting continuously following such a linear change, gradually increasing or decreasing gradually in a curve for a certain time, gently, It can be a smooth jet.

Therefore, the bather can be provided with a jet of the image of the returning wave to the bather, and since such a wavy jet changes over time with a complicated and stimulating and gentle change, the bather surprisingly changes the jet. While you can enjoy the sex,
It is possible to obtain a sensational massage feeling, and it is possible to prevent a bather's body from becoming accustomed to the pattern of jet change, not feeling stimulus, and becoming tired of bathing in air bubbles.

In addition, a jet of the same strength does not continuously hit the same part of the bather's body for a long time, so that the bather can be prevented from feeling pain and discomfort, and bathing for a long time is comfortable Can be done.

The rotation speed change curve (Q) shown in FIG. 13 shows that the rotation speed of the circulation pump (P) changes in a wave-like manner with respect to time, and the rotation speed is partially quadratic, cubic,
Or, it is changed like a quadratic function or the like.

In this way, by partially functionally changing the waveform of the rotation speed change curve (Q), the ejection amount can be changed over time with a multidimensional function such as a quadratic function, a cubic function, or a quartic function. The bather can be provided with a jet of images of waves that vary in period and amplitude, but vary smoothly.

In addition, by setting programs of various functions in the memory (m) of the control unit (C), the amount of jet can be changed to various wave shapes, so that the bather can use various jet forms. The rotation speed change curve (Q) shown in FIG. 14 is obtained by synthesizing all the rotation speed change curves (Q) shown in FIG. 7 to FIG. is there.

The synthesis of the rotation speed change curve (Q) can be set to an arbitrary combination, and the optimal jet (period, intensity,
Gentleness) can be given.

In this way, for example, the period and amplitude of the ejection amount that changes in a wavy manner are made irregular, and the change time of the region with a large ejection amount and the region with a small ejection amount is shortened, thereby partially reducing the acupressure effect. High jet.

In addition, since there is no smooth change in the ejection amount as a whole, it is possible to always have a stimulating jet.

In the above configuration, the gist of the present invention resides in that the rotation speed of each of the circulation pumps (P), (P), and (P) is periodically changed with different phases.

For example, as shown in FIG. 15, each circulating pump (P) connected to the foot-side, back-side, and ventral-side jet nozzles (2), (3), and (4) through the hot water supply pipe (11). ) (P)
The rotation speed of (P) is varied by a half cycle, so that the rotation speed is periodically changed in a sine function with respect to time (t).

In this manner, the baths of the program wave blows having different phases are jetted from the jet nozzles (2), (3), (4), respectively, so that the program wave blows having different phases are mutually connected in the bathtub body (1). Because they can interfere and increase or decrease the amplitude to form a new interference wave, the bather can enjoy the comfort of leaving the body in the gently fluctuating interference wave. it can.

Also in other program wave blow, and
Wave blow A described in the aforementioned Japanese Patent Application No. 1-73367.
The same effect can be obtained with BC.
