Abstract

PURPOSE:To enjoy the unexpectedness of a change in a jet stream by controlling the rotating speed of a circulating pump through a control part, changing the rotating speed in wares and also linearly in terms of time and partially linearly or curvedly changing the rotating speed. CONSTITUTION:The rotating speed of a circulating pump P is controlled through an inverter I by a control part C and the ejection quantity of bathing hot water is periodically changed. Then, a flow rich in the change is made. At such a time, the rotating speed of the circulating pump P is programmed in a memory (m) of the control part C so as to be partially linearly or curvedly changed concerning time (t). Then, a program wave blow is obtained. Namely, a rotating speed change curve Q changes the rotating speed of the circulating pump P in waves and also linearly in terms of the time (t) and changes the rotating speed linearly or curvedly partially. In such a case, the period and amplitude of the rotating speed change curve Q to be changed in waves are disordered. Further, the rotating speed is successively increased linearly to the fixed high rotating speed and afterwards, it is held for fixed time. Next, the rotating speed is successively decreased linearly or curvedly to the fixed low rotating speed and afterwards, it is held for fixed time.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial field in Icheon The present invention relates to a bubble-generating bathtub with a variable spouting amount.

(Exposure) Conventional technology In the past, as an example of a bubble-generating bath cypress, a bath circulation passage was interposed between the bathtub body and the circulation pump, and an air intake part was connected to the nine circulation passages of the bathtub. It is possible to continuously spray a bubble-filled bath into the fabric tank body, and the rotation speed of the Naekan bomb is controlled by a control unit to adjust the amount of bubble-mixed bath that is ejected. There is.

(c) Problems to be Solved by the Invention However, the above-mentioned bubble-generating bath cypress has a jetting amount of ′:Jη
However, since the amount of ejection does not change dynamically, the body of the bather has a
There has been a problem in that the bather's body becomes stimulated by the jet only by being hit by a strong jet, and the acupressure effect of the jet is reduced, causing the bather to get tired of 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 pain and discomfort to the bather, making it difficult to bathe for a long time.

Therefore, you will never get tired of taking a bubble bath for a long time.
Li 1st class, for example, the stimulation and gentleness are 11,? It has been desired to develop a bubble-generating cypress bath that can generate a jet stream that changes dramatically.

(2) Means for solving the problem Therefore, in the present invention, a bath circulation flow path is interposed between the bathtub body and the circulation pump, and an air intake part is connected to the bath circulation flow path, In a bubble-generating bathtub configured to be able to spout bath water mixed with bubbles into the bathtub body, the rotation speed of the above-mentioned circulation pump can be controlled via a control unit, and the rotation speed of the circulation pump is changed in a wave-like manner with respect to time. The present invention aims to provide a bubble-generating bathtub in which the amount of hot water spouted is variable and characterized in that the number of revolutions is partially changed linearly or linearly.

(e) Sakugawa effect According to the present invention, the following effects are produced.

In other words, by partially changing the rotational speed of the circulation pump linearly or curved, the ejection amount can be changed linearly to gradually increase or decrease, or remain unchanged for a certain period of time. It is possible to maintain a constant jet flow with a stimulating sensation, and also to create a gentle and smooth jet flow by continuously increasing or decreasing the jet flow in a curved manner for a certain period of time following such linear changes. It can be done.

Therefore, the jet stream with the image of waves approaching and returning to the bather is 1
-i- At the same time, the wavy jet changes over time in a complex manner with stimulation and gentleness, so bathers can enjoy the unexpectedness of the changes in the jet, and even when they hit it. The bather's body will not become accustomed to the changing pattern of the jet flow and no longer feel stimulation, and the bather will not get tired of bubble bathing.

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, making it comfortable to take a bubble bath for a long time. can be done.

In addition, in the bubble-generating bath (A) that has become disastrous as described above,

Further, the specific structure of the operation panel section (6), remote control 1, controller 1, and roller (30) is disclosed in the above-mentioned patent application No. 1-733.
The structure is similar to that described in No. 67.

In the above configuration, the gist of the present invention is to control the rotation speed of the circulation pump (P) via the inverter (1) by the control unit (
C), by periodically changing the amount of hot water jetted out, a flow rich in variation is created, and the jet stream is created in the image of waves approaching the bathing table and returning.'j. In the wave blowing, the rotation speed of the circulation pump (P) is controlled so that the rotation speed can be partially changed linearly or curvedly with respect to time (1), as shown in FIG. The reason is that the program wave blow can be obtained by programming the memory (m) of the section (C), and will be explained below with reference to FIG.

That is, FIG. 7 is an explanatory diagram showing the relationship between the rotation speed of the circulation pump (P) and the interval (L) between 15 1 6 11.1, and (Q)
shows the rotational speed change curve of the bleached ring bomb (P).

And the rotation speed change curve (Q) is the circulation pump (1))
li-; 1 inversion,] 1! j interval (L) is changed in a wavy manner, and the number of quadruple rotations is partially changed in a linear or curved manner.

At this time, the period and amplitude of the rotational speed change curve (Q) that changes in a wavy manner are made irregular. For example, set the period to 60 seconds, 7
While changing the amplitude irregularly such as 0 seconds, 45 seconds, 50 seconds, etc., the amplitude was changed from 1600 to 3000 r. p
．． m, 1500-2900r. p. m,
I [100 ~ 2500r. p. m, j500～
290 Or. p. You can avoid irregular changes like m...

Moreover, the number of quadruple rotations is gradually increased linearly to maintain a constant high IC1.
After setting the number of revolutions, maintain the same high and same number of revolutions for a certain short time (for example, 20 seconds), and after gradually decreasing the number of revolutions linearly or curved to a constant low number of revolutions, Constant 11! t
He maintains the same low number of fours.

Furthermore, when increasing or decreasing the 11i1 rotation speed linearly to the one-stroke rotation speed, it may be changed in steps.

In this embodiment, both the period and the amplitude of the rotation speed change curve (Q) can be made irregular as described above, or both or either one can be made regular. In addition, while the rotational speed changes from a maximum to a decrease or from a decrease to an increase, the rotational speed is maintained at a high rotational speed or a low rotational speed for a certain short period of time. In particular, it can also vary from an increase to a decrease or from a decrease to an increase.

In addition, the above-mentioned period and amplitude are stored in the memory (
(m) can be changed according to a preset program.

In this way, by partially changing the rotation speed of the circulation bomb (P) linearly or curved, the ejection amount can be changed linearly to gradually increase or gradually decrease for a certain period of time. Alternatively, the jet flow can be kept constant without changing to produce a stimulating jet, and the jet flow can be gently increased or decreased in a curved manner for a certain period of time following such linear changes. , a smooth jet 17 1 8 flow can be obtained.

Therefore, a jet of water with the image of waves approaching and returning to the bather -
lj. At the same time, bathers can enjoy the unexpectedness of the changes in the jet flow as the wave-like jet changes in a complex way, giving a sense of stimulation and gentleness. A soothing massage feeling can be obtained, the bather's body will become accustomed to the changing pattern of the jet flow, and the bather will not feel stimulated, and the bather will not get tired of bubble bathing.

In addition, the jet stream of the same strength is not continuously applied to the same part of the bather's body for a long time, which prevents the bather from feeling pain or discomfort, and prevents bubbles from entering for a long time. You can do it comfortably.

Moreover, FIGS. 8 to 14 show rotational speed change curves (Q) as other embodiments.

That is, the rotational speed change curve (Q) shown in FIG. 8 shows the rotational speed of the circulation pump (P) at iF.
The amplitude is changed at a chordwise constant period (for example, 1 minute) and within a constant quadrupling number range (for example, within a range of 1600 to 3000 rpm).

Further, the period of the rotational speed change curve (Q) can also be made indefinite. For example, change the period to 1 minute, 2 minutes, 1 minute, 3 minutes.
Parenting can be performed irregularly for minutes, or for 10 seconds, 20 seconds, 10 seconds, 30 seconds.

The amplitude can also be changed and adjusted.

In this way, the rotation speed of the circulation pump (1) is changed over time (1
), by making periodic changes in a sinusoidal manner, the amount of water jetted from each of the jetting nozzles (2), (3), and (4) containing bubbles is also changed in a periodic manner in a sinusoidal manner. This creates a realistic jet stream that resembles the wave that approaches and returns to the bather, 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 a surprising jet flow for bathing.
It is also possible to realistically create jets of waves.

Therefore, 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 can provide acupressure, massage-like effects, etc., so that the bather does not get tired of bubble bathing. There is no problem of putting it away.

In addition, the jet stream of the same strength is not continuously applied to the same part of the bather's body, which prevents the bather from feeling pain or discomfort. ．． This allows you to comfortably take a long bubble bath.

That is, in the ninth country, the rotation number capsulation curve (Q) gradually increases the rotation number of the circulation pump (P) by 1. ．． I] curve.

Such a rotational speed change curve (Q) is determined over a certain period of time (for example, 3
The number of quadruples within a certain range (for example, 1,500 to 80 minutes)
00r. I). It can be shaped by changing gently within m).

In addition, the rotational speed change line (Q) shown in Fig. 10 shows the change in the number of rotations of the beat ring bomb (1)) between 11 and r (L) in a gentle curve convex to F. ing.

Such a quadrupling number change curve (Q) is determined over a certain period of time (for example, 3
within a certain range (for example, 1500 to 30
00r. l). It can be formed by making a gentle change within m).

In this way, the rotation speed of the circulation pump (P) is set to 11.7.
Regarding No. 11, since it can be changed gently in a curve of 4 upwards or 1 downward, the bather can enjoy the change in the amount of jet flow over time, and the bather's body is able to respond to the stimulation of the jet flow. This eliminates the problem of the bather getting used to the bubble bath and getting bored with it.

In addition, the jet stream of the same strength does not continuously hit the same part of the body on the bathing table, and the amount of jet stream changes gradually, so it does not cause pain or discomfort to the bather. Even if the bather is a child or an elderly person, there is no risk of physical danger.

Moreover, 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 (1), and makes the amplitude and period irregular.

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

In this way, by making the amplitude and period, or only the amplitude, of the rotational speed change curve (Q) irregular, the jets coming out of each jet nozzle (2), (3), and (4) can be made to have a wave pattern. This allows bathers to experience the gentle, smooth comfort of natural waves.

In addition, the rotation number change curve (Q) shown in the beat 12 diagram is fM'
i The four rotations of Ribonpu (P) with respect to time (1),
If you avoid changing in a wave-like manner, the rotation speed will become female in a linear manner.

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

Therefore, the jet stream has the image of waves approaching and returning to the bather.
In addition to the wavy jet flow, the stimulation changes over time in a complex manner, allowing the bather to enjoy the unexpectedness of the change in stimulation, as well as the sensation of being hit. It is possible to obtain a massage feeling, and the bather's body does not become subject to a pattern of irritation and inflammation, and the bather does not get bored with bubble bathing.

In addition, a jet of the same strength was placed on the same part of the body of a person entering Kyoto for a long time.
There is no continuous contact for a long time, the bather can be prevented from feeling pain or discomfort, and the bather can comfortably take a bubble bath for a long time.

In addition, the rotation speed change curve (Q) shown in FIG. ,
Or it is changed in a multidimensional function such as a quartic function.

In this way, by partially functionally changing the waveform of the rotation speed change curve (Q), the ejection amount can be changed in a multi-order manner such as a quadratic function, a cubic function, or a quartic function. Because it can be varied functionally, it can provide the bather with a jet of wave imagery that varies smoothly, albeit irregularly, in period and amplitude.

In addition, by setting programs for many types of functions in the memory (m) of the control unit (C), it is possible to change the spray amount 2 3 2 4 into various wave shapes. You can enjoy various jet forms.Also, the 14th
The rotational speed change 1 peak line (Q) shown in the figure is from the above-mentioned figure 7 to
This is obtained by combining all of the rotational speed change curves (Q) shown in FIG. 13.

The synthesis of such 111 rotation number change curves (Q) can be set to any combination, so that the optimum jet flow (period, strength, gentleness) can be determined for 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 amount of ejection and areas with a small amount of ejection can be made short intervals, so that partial acupressure can be applied. A highly effective jet stream can be obtained.

In addition, since there is no smoothness in the change in the amount of ejection as a whole, the jet flow can be irritating to '7i'i IFI.

In addition, FIG. 15 shows a bubble generating bathtub (
A) shows foot, dorsal, and ventral jet nozzles (2)
(2) (3) (8) (4) (4) and the circulation pump (1)) (P) (P) respectively to the bath circulation flow path (D)
(1)) (1)), and each circulation pump (1)) is connected to the control unit (
C).

Therefore, in such a bubble-generating bath (A), each jet nozzle (2) (3) (4) has a different jet flow form (Mile 1,
Blow, shiatsu blow, pulse blow, wave blow,
Cycle blow, program blow, and program wave blow) baths can be blown out.

At this time, by changing the rotation speed of each circulation pump (1) according to a given rotation speed change curve (Q), each jet nozzle (2) (3) (4) has a program wave of the form y4. Able to squirt a bath of blows.

In addition, even if the rotational speed change curve (Q) in the form of the same program wave blow, the period and amplitude (by increasing the phase), each jet nozzle (2) (3) (4) It is possible to make a type of bath water gush out.

2 5 2 6 In this way, in the wooden 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.
