Abstract

PURPOSE:To enjoy the change of a stimulated feeling for a bathing person by controlling the rotating speed of a circulating pump through a control part and changing the rotating speed in waves and also linearly in terms of time. CONSTITUTION:The rotating speed of a circulating pump P is controlled through an inverter I by a control part C and the emitting 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 linearly 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 time (t) and the period and amplitude of the rotating speed change curve Q to be changed in the manner of liquid is disordered. Further, the rotating speed is successively increased to the fixed high rotating speed and afterwards, it is held in fixed short time. Next, the rotating speed is successively decreased linearly to the fixed low rotating speed and afterwards, the rotating speed is held for the fixed time.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industry (2) Field of Application The present invention relates to a bubble-generating bathtub in which the amount of hot water spouted is variable.

(Exposure) Conventional technology As an example of a bubble-generating Rakuhinoki, a bath water circulation flow path is interposed between a bath body and a circulation pump, and the same bath water is heated for 1 hour.
The air intake part is connected to the ri circulation path, so that the bath water mixed with air bubbles can be spouted into the bath 1 carbonate body, and the rotation speed of the circulation pump is controlled by the control unit, so that the bath water mixed with air bubbles can be spouted. There are some that allow you to adjust the amount of ejection.

(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 may cause damage to the body of the bather. There is a problem that the bather's body becomes stimulated by the jet, and the acupressure effect of the jet is reduced, causing the bather to get tired of bubble bathing. there were.

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 take a long bath.

For this reason, it is desired to develop a bubble-generating 41 bathtub that can generate a jet stream that does not get tired even when taking a bubble bath for a length of 11η, for example, a jet stream that has a stimulating sensation and whose stimulating sensation changes over time. Ta.

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

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

In other words, by expressing the rotational speed of the circulation pump linearly, the ejection amount can be kept linearly increasing or decreasing for a certain period of time, or kept constant and stimulated. It is possible to create a jet stream with a pleasant feeling.

Therefore, the bather can experience the image of a jet of waves approaching the bather and returning, and since the wavy jet undergoes complex changes in the sensation of stimulation over time, the bather is surprised by the changes in the sensation of stimulation. Not only can you enjoy the forest, but you can also get a massage sensation that feels like being tapped, and your body won't get used to the pattern of changing stimulation sensations, so you can become a bubble bather. You will no longer get bored.

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 possible to take a bubble bath for a long time. can also be done comfortably.

(f) Examples Embodiments of the present invention will be described with reference to the drawings.

(A) shown in FIGS. 1 to 3 is a bubble-generating bathtub according to the present invention, and the bubble-generating bathtub (^) is made of a box-shaped bathing cypress wood body (1) with an opening at the top. Leg-side jet nozzles (2) with automatic variable jet volume on the wall and left and right side walls (2)
, dorsal jet nozzle (3) (3), ventral jet nozzle (4
) There are a total of six items in (4).

Such foot side, dorsal side, and ventral side jet nozzles <2) (3) (4
) is described in the patent application filed by the applicant earlier.
The structure is similar to that described in No.-73367.

The bathtub body (1) has a flange-like edge (1a) with a constant width on the periphery, and an air intake part (5) on the edge (1a).
) and the operation panel part (6) are integrally attached, and a vertically elongated recess (1.b) (1.
．． b), and on the sloped surface (1"b) (1'b) of the same l (1 part (+-b) (lb) on the side facing the rear wall (dorsal side),
The ventral side jet nozzle (4) (4) is placed toward the center of the rear wall.

Moreover, the ventral side jet nozzle (4) is installed at a higher position than the other leg side and dorsal side jet nozzles (2) and (3) to ensure that the bath water reaches the ventral side, chest side, and other parts of the human body. I am trying to make it possible to apply it to.

In addition, a pump protection case (K) is installed outside the bubble generating bathtub (A), and inside the case (K),
Circulation pump (P) that circulates bath water and bomb (P)
A filter (F) that filters the bath water circulated by the filter, a pump drive motor (M) that drives the pump (P), and a valve body for opening and closing the motor (M) and the nozzle valve of each jet nozzle. A motor (old), a motor (M2) for opening and closing the valve body for adjusting the amount of air bubbles of each air bubble amount adjustment valve (described later), and a control section (C) that controls the driving of the electric three-way valve (G) are provided.

As shown in FIG. 3, the control unit (C) includes a microprocessor (MPU), an input/output interface, 2. (a
) (b) and memory (m) consisting of ROM and RAM
and a timer (L').

Further, a bath water circulation channel (D) is interposed between the circulation pump (P) and the bubble generating bath stirrer (A).

That is, the bath water circulation flow path (D) includes a bath water suction pipe (10) for sending bath water from the bubble generating bathtub 5 6 (8) to the circulation pump (P), and from the circulation pump (P). It consists of a forced bath water pipe (l1) for sending bath water to the bathtub (A).

The bath water suction pipe (TO) is connected to the bathtub body (1).
Connect one end to the inlet (1 m) opened at the bottom of the
The other end is connected to the water inlet of the circulation pump (P) so that bath water is sucked into the circulation pump (1), while the forced bath water pipe (l1) is connected to the water outlet of the circulation pump (P). One end is in communication with the other end, and the other end is connected to the ejection nozzles (2), (3), and (4), respectively.

Moreover, the above-mentioned suction port (lm) is provided at a lower position than the foot side/dorsal side jet nozzles (2) and (3).

In addition, the above-mentioned air intake part (5>) and each jet nozzle (2)
(3) There is an intake pipe (12) (
13) (14) is installed, and each jet nozzle (2)
(3) Utilizing the negative pressure generated when the bath water is spouted in (4), the air taken in from the air intake part (5) is passed through the intake pipes (12), (13), and (14) to each jet nozzle. (2) (3) (4) Each jet nozzle (
2) From (3) and (4), the bath water mixed with air bubbles can be spouted into the bathtub body (1).

Furthermore, as shown in FIG. 3, an inverter (1) is interposed between the pump drive motor (M) that drives the circulation pump (P) and the control section (C). )
By controlling the rotation speed of the circulation bomb (P) by changing the output frequency of the pump, the rotation speed of the circulation pump (P) can be changed smoothly and reliably.

In addition, as shown in Fig. 3, a pressure detection sensor (S) for detecting the pressure of the bath water being forced to flow through the pipe (11) is installed in the middle of the pipe (11). The detection results from the sensor (S) are sent to the control unit (C), and the control unit (C) adjusts the jetting pressure of the bath water spouted from each jetting nozzle (2), (3), and (4) to the pump. Rotation speed of drive motor (1) and each jet nozzle (2) (3) (4)
It is controlled by changing the amount of opening and closing.

Further, the pressure detection sensor (S) is also used as a water level detection sensor for detecting the amount of hot water filled in the bathtub body (1).

By using such a water level detection sensor,
When the bath water does not reach a certain water level, the control unit (C) is configured to prevent the control unit (C) from starting spouting the bath water mixed with air bubbles into the bathing cypress wood body (1), that is, starting the blow operation.

In addition, as shown in Fig. 3, a bath water temperature detection sensor (T) is installed in the middle of the bath water forced-feeding pipe (11) to detect the temperature of the bath water that is force-fed inside the pipe (11). 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 blow operation, the above-mentioned patent application qt+-
It is possible to take the following jet forms: mild blow, shiatsu professional, pulse blow, wave blow, cycle blow, and program blow as described in 73se No. 7, and it is also possible to change the strength level of each jet form. .

Further, the operation panel section (6> that is integrally constructed with the air intake section (5) will be explained with reference to FIGS. 4 and 5. The panel section (6>) is formed in a substantially rectangular shape. , the upper surface is formed in a downward slope toward the inside of the bathtub body (1), and the uppermost surface of the operation panel section (6) is provided with a cover that covers the operation display section (6a).

Next, the air intake section (5) will be explained.

The air intake section (5) is mainly composed of an intake case (5a) formed in a substantially rectangular box shape. That is,
The intake case (5a) is open at the top and has an air discharge hole at the bottom to form an air flow passage (I,) inside, and the upper edge of the intake case (5a) is opened outward. The air flow passage (1,), which is formed by repeating the flange (5b) and is open at the top, is inside the intake case (5a).
C) is divided into three independent rooms, which are divided into the 1st, 2nd, and 3rd intake chambers (5d) (5e) (5F).
I'm doing it.

Moreover, at the top of each intake chamber (5d) (Fee> (5F), an upper one-piece FFi (5g) and a lower partition plate (5h) are provided horizontally with a constant interval between them. An upper l1'l sound pipe (51) and a lower muffling vibrator (5j) are vertically installed on the partition plates (5g) and (5b), respectively, and the upper and lower sides thereof are communicated via the pipes.

In other words, each of the muffling pipes (5j) (5i) is interposed in the middle of the airflow passage (1,), and the upper muffling pipe (51) and the lower muffling pipe (5j) are naturally connected to each intake chamber ( 5d) (5e) (55), so the noise emitted from each muffling pipe (5i) (5N) is absorbed by the large-volume intake chamber (5(1) (5e) (51 ') The sound waves that flow into the room resonate, interfere with each other, and cancel each other out, resulting in a sound silencing function.

Furthermore, an intake pipe connection part (5k) (5m) (5n) is provided at the bottom of each intake chamber (5d) (5e) <5r), and an intake vibe is connected to each connection part (5k) (5m) (5n).

) through each intake pipe (12), (1.3), and (14) so as to be able to adjust the amount of air sucked into each blowout nostle (2), (3), and (4).

In this way, the individual jet nozzles (2) (3) (4)
In order to be able to adjust the amount of air sucked into the bath water, the amount of bubbles mixed into the bath water spouted from each jet nozzle (2), (3), and (4) is increased to change the jet strength. It can be made to stand.

), and ir'. A blow state display section (33) for displaying the blow state is provided in the upper half of the surface, and the lower front surface I'. Various membrane switch type operation switches (34) are provided in the section. In addition, among the various operation switches (34), (35
) is a program wave blow switch for operating the program wave blow which is the gist of the present invention. (3B) (36°) is a bubble volume increase/decrease switch, and by operating each switch (36) (36°), each bubble volume adjustment valve (
50) Adjust the opening/closing amount of (51) and (52) to
The amount of air bubbles mixed into the bath water spouted from the dorsal and ventral jet nozzles (2), (3), and (4) can be adjusted.

In addition, the different structures of the panel section (6) made by J'A and the remote control 1, controller 1, and roller (30) are described in the above-mentioned patent application No. 1-73.
The structure is similar to that described in No. 367.

In the configuration as described above, the gist of the present invention is to control the rotation speed of the circulation pump (P) by the control unit (C) via the inverter (1), and periodically control the spouting member of the bath water. By avoiding change, we create a flow rich in change, creating a jet image of waves that approach and return to famous people! In the wave blowing, the rotation speed of the circulation pump (I) is controlled so that the rotation speed can be changed linearly between H and f (C) as shown in Fig. 7. The purpose is to program the memory (m) of the section (C) to obtain a program wave block, which 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 (l) and time (1), and (Q) shows the rotation speed change curve of the circulation pump (P).

And the rotation speed change curve (Q) is the circulation pump (I))
The number of rotations is changed in a wave manner with respect to time (L), and the number of rotations is changed linearly to 15 1 6 and Jl-.

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 avoiding irregular changes such as 0 seconds, 45 seconds, 50 seconds, etc., the amplitude was set to 1600 to 3000 r. p
．． m, +5[10-2900r. p. m S160
0-2500r. p. m, 1500-290 Or. p
．． It can be changed irregularly such as m...

Moreover, after the rotational speed is gradually increased linearly to a constant high rotational speed, the same high rotational speed is maintained for a certain short period of time (for example, 20 seconds), and then the rotational speed is gradually decreased linearly. After the rotation speed is set to a constant low rotation speed, the same low rotation speed is maintained for a certain period of time.

Furthermore, when increasing or decreasing the rotational speed to a constant rotational speed, the rotational speed may be changed in steps.

In this embodiment, both the period and the amplitude of the rotational speed change curve (Q) are made irregular as described above, but both j'. '
L < can also be made regular. Also, while the number of quadruple rotations changes from an increase to a decrease, or from a decrease to +19 people, a high or low rotation number is maintained for a certain period of time, but by eliminating the retention of the same rotation number, It is also possible to instantaneously change from increase to decrease or from decrease to 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 linearly changing the rotation speed of the circulation pump (P), the ejection amount can be maintained at a certain level of 11! Between i,
The jet flow can be linearly increased or decreased, or can be kept constant to provide a stimulating jet flow.

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 a massage sensation that feels like being tapped, and your body will not get used to the pattern of changing stimulation sensations, and you will not get tired of bubble bathing. There will be no more problems.

1 7] 8 In addition, the jet stream of the same strength does not hit the same part of the body on the bath table continuously for a long time, which prevents the bather from feeling pain or discomfort. You can comfortably take a bubble bath.

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

In other words, the rotation speed change curve (Q) shown in FIG. The amplitude is varied within a several 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.
minutes...or 10 seconds, 20 seconds, ]0 seconds, 30 seconds
It can be changed irregularly, such as every second.

The amplitude can also be changed and adjusted.

In this way, the number of revolutions of the circulation pump (l) can be adjusted between 1 samurai (
By making a periodic change in L) in a sinusoidal manner, the amount of bubble-mixed bath water ejected from each of the jet nozzles (2), (3), and (4) is also made to change in a sinusoidal manner. The bathers can enjoy the comfort of letting their body rest in the gently swaying waves, creating a realistic image of the jets of waves that approach and return to the bather.

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

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 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, making it possible to comfortably take a bubble bath for a long time. .

In addition, the rotation speed change curve (Q) shown in FIG. There is.

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. p. +n).

Further, the rotational speed change curve (Q) shown in FIG. 10 shows that the rotational speed of the circulation pump (P) is gradually changed to F with respect to time (1) in a four-curve manner.

This rotational speed change line (Q) is determined over a certain period of time (for example, 3
The number of quadruple rolls within a certain range (for example, 1500 to 30 minutes)
00r. p. +n).

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

In addition, the jet of the same strength does not continuously hit the same part of the body on the bath table, and the amount of jet changes gradually, which may cause pain or discomfort to the bather. There is no risk of physical danger even if the bather is a child or an elderly person.

In addition, the rotational speed change line (Q) shown in FIG.
'The rotation speed of the i-ring pump (P) with respect to time (L),
It changes in a wave-like manner, and the amplitude and period are 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 rotation speed change curve (Q) irregular, each jet nozzle (2
) (3) The jet stream emitted from (4) can be made to resemble natural waves, giving bathers the same gentle, smooth comfort as natural waves.

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 jet 21 2 2 can be linearly increased or decreased for a certain period of time. It is possible to make a jet flow with a stimulating feeling by changing it or keeping it constant without changing it, and the jet amount can be continuously changed in a linear manner, and for a certain period of time, the jet amount can be gradually increased to a maximum or gradually in a curved manner. It can be reduced to create a gentle, smooth jet.

Therefore, it is possible to give the bather a jet of water that resembles waves approaching and returning, and since the wavy jet changes over time in a complex manner with stimulation and gentleness, the bather is able to experience the changes in the jet. Not only can you enjoy the unexpectedness, but you can also get a massage sensation that feels like being tapped, and the problem that the bather's body gets used to the changing pattern of the jet flow, stops feeling stimulation, and gets tired of bubble bathing is avoided. It can be prevented.

In addition, a jet of the same strength is applied to the same part of the bather's body for a long time.
There is no continuous contact for 1.1 hours, which prevents the bather from feeling pain or discomfort, and allows a comfortable bubble bath for a long time.

In addition, the rotation speed change t+h line (Q) shown in FIG. It is changed in a multidimensional function such as a quartic function or a quartic function.

In this way, by partially functionally changing the waveform of the rotation speed change line (Q), the ejection amount can be changed over time by a multidimensional function such as a quadratic function, a cubic function, or a quartic function. Because it can be varied cyclically, it is possible to create an image of a jet stream of waves that smoothly change, although the period and amplitude are irregular, to the bather.

Furthermore, by setting programs for many types of functions in the memory (m) of the control unit (C), it is possible to change the amount of jets into various waveforms. The rotational speed change curve (Q) shown in Figure 14 is obtained by combining all of the rotational speed change curves (Q) shown in Figures 7 to 13 above. It is.

It is possible to set the rotational speed change curve (Q) to a combination or any combination of the rotational speed change curves (Q), so that it is possible to adjust the jet stream (period, strength, gentleness) that is most suitable for the bather. I can do it.

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.

In addition, FIG. 15 shows a bubble-forming/-h bathtub (A) as another embodiment, and the foot side, dorsal side, and ventral side jet nozzles (
2) (2) (3) (3) (4) (4) The circulation pumps (P) (p) (p) are connected to each other via the bath water circulation channels (D) (D) (D). Each circulating pump (1) can be controlled by a control section (C) via an inverter (1).

Therefore, in such a foaming bathtub (A), different jet flow forms (mild blow, acupressure blow, pulse blow, wave blow,
It is possible to eject bath water for cycle blow, program blow, and program wave blow.

At this time, by changing the rotation speed of each ring pump (I) according to a given rotation speed change curve (Q), each jet nozzle (2), (3), and (4) It is possible to eject bath water with a program wave blow.

In addition, even if the rotation speed change curve (Q) has the same program wave blow, by varying the period, amplitude, and phase, each jet nozzle (2> (3) and (4)) can be It can gush out hot water.

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.
