Abstract

PURPOSE:To really impart a jet stream of a moving wave image to a bathing person by making the number of rotations of a recirculation pump controllable and cyclically changing the same in a sine-functional manner with respect to a time. CONSTITUTION:The number of rotations of a recirculation pump P is cyclically altered by a control part C through an inverter I to cyclically change the jet amount of bath hot water to form a stream rich in change and a jet stream of a moving wave image is imparted to a bathing person. At this time, the number of rotations of the recirculation pump P is programmed in the memory of the control part C so as to be cyclically changed in a sine-functional manner with respect to a time to make it possible to obtain program wave blow.

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 hot water jetted out changes periodically.

(b) Conventional technology Conventionally, as an example of a bubble-generating bathtub, a bath water circulation flow path is interposed between the bathtub body and a circulation pump, and an air intake part is connected to the bath water circulation flow path. Some bathtubs are capable of spouting bath water mixed with air bubbles into the bathtub body, and the number of rotations of a circulation pump is controlled by a control unit to adjust the amount of water mixed with air bubbles being ejected.

(c) Problems to be Solved by the Invention However, although the above-mentioned bubble-generating bathtub can adjust the amount of ejection, the amount of ejection does not change automatically, so it does not affect the body of the bather. There is a problem in that when a bather's body is simply hit by a jet of a monotonous strength, the bather's body becomes stimulated by the jet, the acupressure effect etc. of the jet is reduced, and the bather becomes bored with bubble bathing.

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

(d) Means for Solving the Problems In the present invention, a bath water circulation flow path is interposed between the bathtub body and the circulation pump, and an air intake section is connected to the bath water circulation flow path so that the bathtub In a bubble-generating bathtub configured to be able to spout bathwater mixed with bubbles into the main body, the rotation speed of the circulation pump described above can be controlled via a control unit, and the rotation speed of the circulation pump is adjusted according to a sine leap number with respect to time. The purpose of the present invention is to provide a bubble-generating bathtub in which the amount of hot water ejected periodically changes.

After installation, the detection results from the sensor (T) are sent to the control unit (C), which controls the pump drive motor (M) and each jet nozzle (2), (3), and (4). That's what I do.

By using such a bath water temperature detection sensor (T), when the hot water supply does not reach a certain water temperature, the blowing operation by the control unit (C) is prevented from starting.

In this way, the blowing operation by the control unit (C) is prevented from starting if the bath water does not reach a certain water level and a certain water temperature.

In addition, in the above-mentioned blowing operation, the above-mentioned patent application/I'l

In addition, the operation panel section (6) and remote controller (3
The specific structure of 0) is described in the above-mentioned patent application No. 1-73387.
The structure is the same as that described in the issue.

In the above configuration, the gist of the present invention is to control the rotation speed of the circulation pump (P) via the control unit (<1).
In the wave blow, which creates a varied flow by periodically changing the jet amount of bath water by C), and giving a jet of water that resembles a wave that approaches and returns to the bather, As shown in FIG. 5, the memory ( m) to obtain a program wave blow, which will be explained below with reference to FIG.

In other words, Fig. 5 shows the rotation speed and time (
1), in which (Q) shows a rotation speed change curve of the circulation pump (P).

The rotational speed change curve (Q) shows the rotational speed of the circulation pump (P) within a constant period (for example, 1 minute) in terms of a sine exponential with respect to time (1) and within a constant rotational speed range (for example, 16
The amplitude is varied within the range of 00 to 300 r, p, i).

Further, the period of the rotational speed change curve (Q) may be indefinite. For example, change the period to 1 minute, 2 minutes, 1 minute, 3 minutes.
Minutes...or 10 seconds, 20 seconds, 10 seconds, 30 seconds
It can be changed irregularly, such as every second.

The amplitude can also be changed and adjusted.

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

In this way, the rotation speed of the circulation pump (P) is changed over time (1)
By making a periodic change in a sine exponential manner, the amount of bubble-mixed bath water ejected from each jet nozzle (2), (3), and (4) is also periodically changed in a sine exponential manner. This allows the bather to experience a realistic jet of water that resembles waves rolling in and out, allowing the bather to fully enjoy the comfort of letting their body rest in the gently swaying waves.

In addition, by changing the rotation speed of the circulation pump (P) at irregular intervals, it is possible to provide unexpected jets to bathers.
It is also possible to realistically create jets of waves.

Therefore, with this type of jet flow, the bather's body does not become stimulated by the jet flow, and the jet flow provides acupressure,
A pine surge effect can also be ensured, and the problem of the bather getting bored with bubble bathing does not occur.

In addition, the jet stream of the same strength does not continuously hit the same part of the bather's body, which prevents the bather from feeling pain or discomfort, and allows for a comfortable bubble bath for a long time. Ru.

Moreover, FIGS. 6 to 12 show rotational speed change curves (Q) as other embodiments.

That is, the rotational speed change curve (Q) shown in FIG. 6 changes the rotational speed of the circulation pump (P) in a gently upwardly convex curve with respect to time (1).

Such a rotational speed change curve (Q) is determined over a certain period of time (for example, 3
within a certain range (for example, 1500 to 30
00r, I]l).

Further, the rotational speed change curve (Q) shown in FIG. 7 shows that the rotational speed of the circulation pump (P) is changed in a gently downwardly convex curve with respect to time (1).

Such a rotational speed change curve (Q) is determined over a certain period of time (for example, 3
The number of rotations within a certain range (for example, 1500 to 30 minutes)
00r, pJl).

In this way, since the rotational speed of the circulation pump (P) can be changed over time in a gentle upward or downward curve, bathers can enjoy the change in the amount of ejection over time. At the same time, the bather's body is stimulated by the jet stream, and the problem that the bather gets bored with bubble bathing does not occur.

In addition, the jet stream of the same strength does not continuously hit the same part of the bather's body, and the amount of jet stream changes gradually, so it does not cause pain or discomfort to the bather. There is no risk of physical danger even when the bather is a child or an elderly person.

Further, the rotation speed change curve (Q) shown in FIG. 8 changes the rotation speed of the circulation pump (P) in a wave-like manner with respect to time (1), and makes the amplitude and period irregular.

Further, only the amplitude of the rotational speed change curve (Q) can be made irregular.

In this way, by making the amplitude and period, or only the amplitude, of the rotation speed change curve (Q) irregular, each jet nozzle (2
X3) The jet coming out of (4) can be made to resemble natural waves, giving bathers the same gentle, smooth comfort as natural waves.

Further, the rotation speed change curve (Q) shown in FIG. 9 shows that the rotation speed of the circulation pump (P) is changed in a wave-like manner with respect to time (1), and the rotation speed is changed linearly.

In this way, by linearly changing the rotation speed of the circulation pump (P), the ejection amount can be linearly increased or decreased for a certain period of time, or kept constant without changing. This can create a stimulating jet stream.

Therefore, it is possible to give the bather a jet that resembles waves approaching and returning, and since the wavy jet undergoes complex changes in the sensation of stimulation over time, the bather is surprised at the changes in the sensation of stimulation. Not only can you enjoy sex, but you can also get the sensation of a massage that feels like being tapped, and the bather's body can get used to the pattern of changing stimulation sensations, preventing the problem of getting bored with bubble bathing. can.

In addition, the jet stream of the same strength does not continuously hit the same part of the bather's body for a long time, which prevents the bather from feeling pain or discomfort, and makes it possible to take a bubble bath for a long time. You can do it comfortably.

In addition, the rotation speed change curve (Q) shown in FIG. It's changing.

In this way, by partially changing the rotational speed of the circulation pump (P) linearly or curved, the amount of ejection can be changed linearly to gradually increase or decrease for a certain period of time, or Alternatively, it can be kept constant without changing to produce a stimulating jet flow, and the jet amount can be gradually increased or decreased in a curved manner for a certain period of time following such linear changes, gently. A smooth jet can be created.

Therefore, it is possible to give the bather a jet with the image of waves approaching and returning, and since the wavy jet changes over time in a complex manner with a feeling of stimulation and gentleness, the bather is surprised at the changes in the jet. Not only can you enjoy sex, but you can also get a massage sensation that feels like being tapped, and the bather's body gets used to the changing pattern of the jet flow, and you no longer feel stimulation, which prevents the problem of getting bored with bubble bathing. can do.

In addition, the jet stream of the same strength does not continuously hit the same part of the bather's body for a long time, which prevents the bather from feeling pain or discomfort, and makes it possible to take a bubble bath for a long time. You can do it comfortably.

In addition, 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, and also partially changes the rotation speed in a quadratic function, a cubic function, etc.
Or it is changed in a multidimensional function such as a quartic function.

In this way, by partially functionally changing the waveform of the rotational speed change curve (Q), the ejection amount can be changed over time according to a multidimensional function such as a quadratic function, a cubic function, or a quartic function. Since the wave can be varied, it is possible to provide the bather with a stream of images of waves that change smoothly, although the period and amplitude are irregular.

In addition, by setting programs for many types of functions in the memory (ffi) of the control unit (C), the jet amount can be changed to various waveforms, so the bather can adjust the jet flow at intervals. In addition, the rotational speed change curve (Q) shown in FIG. 12 is as described above. Figures 5 to 11
It is obtained by combining all of the rotational speed change curves (Q) shown in the figure.

The synthesis of the rotational speed change curves (Q) can be set to any combination, so that the optimal jet flow (period, strength, gentleness) can be provided to the bather.

In this way, for example, the period and amplitude of the ejection amount that changes in a wave pattern can be made irregular, and the change time between areas with a large eruption amount and areas with a small ejection amount can be shortened, resulting in a partial acupressure effect. It can be a high jet flow.

In addition, since there is no smoothness in the overall change in jet amount, the jet flow can be irritating at all times.

In addition, FIG. 13 shows a bubble generating bathtub (
A) shows foot, dorsal, and ventral jet nozzles (2)
(2>(3) (3)(4) (4) respectively connect the circulation pump (P) (P) (P) to the bath water circulation flow path (D)
(D) Connected via (D), each circulation pump (P
) can be controlled by a control unit (C) via an inverter (1).

Therefore, in the bubble-generating bath 1 (A), different jet flow forms (mild blow, acupressure blow, pulse blow, wave blow, cycle blow program blow, and program wave blow ) can gush out bath water.

At this time, by changing the rotation speed of each circulation pump (P) according to different rotation speed change curves (Q), different types of program wave blows can be generated from each jet nozzle (2,) (3) (4). You can make bath water gush out.

In addition, even if the rotation speed change curve (Q) has the same program wave blow, by changing the period, amplitude, and phase, each jet nozzle (2), (3), and (4) can have a different form of bath water. can be ejected.

In this way, in this embodiment, since the jet flow form can be varied in a wide variety of ways, it can be widely adapted to the preferences of bathers.

(to) Effect According to the present invention, the following effects are produced.

In other words, since the rotation speed of the circulation pump can be changed periodically in a sine exponential manner with respect to time, the amount of ejected bath water mixed with bubbles can also be changed periodically in a sine exponential manner.
It is possible to give the bather a realistic jet image of waves that come and go, allowing the bather to fully enjoy the comfort of letting their body rest in the gently swaying waves.

Furthermore, by changing the rotational speed of the circulation pump at irregular intervals, it is possible to provide unexpected jets of water to bathers, and it is also possible to realistically create jets that resemble waves.

Therefore, with this type of jet flow, the bather's body does not become stimulated by the jet flow, and the jet flow provides acupressure,
A pine surge effect can also be ensured, and the problem of the bather getting bored with bubble bathing does not occur.

In addition, the jet stream of the same strength does not continuously hit the same part of the bather's body, which prevents the bather from feeling pain or discomfort, and allows for a comfortable bubble bath for a long time. Ru.
