Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is a mechanism that provides a pine surge effect to bathers, and includes an air blow mechanism that blows air bubbles from the bottom of the bathtub into the water in the bathtub, and an air blow mechanism that sucks the water in the bathtub from the bathtub. A jet mechanism that injects a jet flow mixed with air from the side of the bathtub into the water in the bathtub;
The present invention relates to a bathtub system that includes a fall mechanism that sucks water in the bathtub from the bathtub and causes the water to flow from the upper part of the bathtub into the water in the bathtub as a fall flow, and a remote control operation unit that has a switch that individually drives each of these mechanisms.

<Prior art> Conventionally, in bathtub systems equipped with the three modes of air blow, jet, and fall as described above, an air blow switch, a jet switch, and a fall switch are provided in the remote control unit to realize each mode. Each mode is activated by operating each of these switches individually.

If you want any two of the three modes to function at the same time, you only need to operate the two switches corresponding to those modes;
If you want all modes to work at the same time,
All you have to do is operate all the switches.

<Problem to be solved by the invention> In order to realize a full mode in which all three modes function simultaneously, a switch corresponding to a mode other than the one that is already functioning must be operated. Which switch should be operated at this time varies depending on the situation at the time.

For example, when air blow mode is already activated, the jet switch and fall switch will be operated one after the other, whichever comes first; however, if the air blow mode is already activated, The air blow switch and fall switch are operated, and when in full mode, the air blow switch and jet switch are operated. Also, for example, when changing from a state in which air blow mode and jet mode are used together to full mode, the fall switch must be operated, but when the combined mode is air blow mode and full mode, the jet switch must be operated. , when the combination mode is jet mode or full mode, the air blow switch must be operated. Further, when changing from an initial state in which no mode is operated to a full mode state, three switches are operated one by one in any order.

As mentioned above, in order to go from any state to full mode, it is necessary to recognize the current situation and decide which switch to operate depending on the situation at the time. and the required one, two or three depending on the result of the judgment.
You have to operate two switches.

However, due to the large number of mode combinations,
This series of tasks of recognition, judgment, and operation is extremely troublesome as a whole.

The present invention was devised in view of these circumstances, and no matter what the current state of the bathtub system is, it can be fully refilled with a single switch operation, and moreover, with the same switch operation at all times. The purpose is to enable the mode to function.

<Means for Solving the Problem> In order to achieve such an object, the present invention has the following features:
It has the following structure.

The bathtub system of the present invention has an air blow mechanism A
, a jet mechanism B, a fall mechanism C, a remote control operation section 80, and a control means 100, each of which is configured as follows.

The air blow mechanism A blows air bubbles from the bottom of the bathtub 2 into the water in the bathtub. Jet mechanism B
In this method, water in the bathtub is sucked in from the bathtub 2, air is mixed therein, and a jet flow is reflux-injected from the side of the bathtub 2 into the water in the bathtub. Four structure C
The system sucks water in the bathtub from the bathtub 2 and drops it into the bathtub water from the upper part of the bathtub 2 as a fall flow. The remote control operation unit 80 includes an air blow switch _S4 that drives the air blow mechanism A, and jet switches _S6 and _S8 that drive the jet mechanism B.
and a fall switch that drives fall mechanism C.
S ₁₀ , S ₁₂ and a full mode switch S ₂₆ that simultaneously drives all of the three mechanisms A, B, and C described above. When the full mode switch S ₂₆ is pressed for the first time after the power is turned on, the control means 100
While operating the three mechanisms A, B, and C described above under predetermined initial conditions, if it occurs after another switch is pressed, the mechanism that was operating immediately before that operation is operated under the same driving conditions. be.

<Functions> The effects of the above configuration of the present invention are as follows.

Even if the current status of the bathtub system is the initial state with no mode selected, or
Operation of a full mode switch is called a full mode switch operation, whether it is in a single function state where one of the two modes is selected, or in a combined function state where any two modes are selected. With a single and always identical switch operation, the air blow mechanism, jet mechanism, and fall mechanism can all be activated simultaneously to operate in full mode. Moreover, when the full mode switch is pressed for the first time after the power is turned on, the three mechanisms A, B, and C described above are operated under predetermined initial conditions, but the other mechanisms are activated immediately before the full mode switch is pressed. If so, the same mechanism will be operated under the same driving conditions. Therefore, especially when transitioning from the single mode functional state to the full mode functional state, the transition becomes smooth and the pine surge effect on the bather can be maintained constant.

<Example> Hereinafter, an example of the present invention will be described in detail based on the drawings.

Reference numeral 100 denotes a sequence controller configured with a microcomputer, and is designed to control each part using a control system shown by a two-dot chain line.

Next, the operation of the bathtub system of this embodiment will be explained.

When the operation switch _S2 is pressed, the power is turned on and the sequence controller 100 is activated.

Air blow mode Press air blow switch S ₄ to select air blow mode, and sequence controller 10
0 drives the air blow mechanism A. That is,
By starting the air pump 4, compressed air is generated, and this compressed air is force-fed to the plurality of air blow nozzles 10 via the header 8. Then, air blow is performed on the water W in the bathtub from each air blow nozzle 10. The bubbles created by the air blow envelop the entire body of the bather, giving a relatively gentle pine surge effect.

The strength of the air blow is controlled by controlling the phase of the air pump 4. In other words, if you press the air blow amount switch _S14 once, it will change to "strong".
Press twice to switch to "medium", press three times to switch to "low". If you press it again, it will return to "strong" again.
Press air blow switch S ₄ again to stop air pump 4.

The setting conditions for "strong", "medium", and "weak" air blow water volume are determined by sequence controller 1 each time.
00 and displayed on the liquid crystal display panel 82.

Note that the intermittent flow of compressed air generated by the air pump 4 is once narrowed down by an orifice or the like in the muffling tank 6, and then expanded to change into a continuous flow. Therefore, the vibration propagation from the air blow nozzle 10 to the bathtub 2 is Prevented.

Jet mode Press dorsal jet switch S ₆ or foot jet switch S ₈ to select dorsal or foot jet mode, and sequence controller 1
00 drives jet mechanism B. That is,
The circulation pump 14 is started and the water volume switching valve 18 or 20 is opened. As a result, the water W in the bathtub is sucked through the suction port 12, and is vigorously refluxed and sprayed back into the water W in the bathtub from the back side jet nozzle 22 or the foot side jet nozzle 24. Due to the negative pressure generated at this time, air (outside air) is sucked from the air servo 26 and mixed into the jet water stream at the back side jet nozzle 22 or foot side jet nozzle 24, and becomes a jet water stream containing air and is injected into the water W in the bathtub. be done. The jet water impinges on the bather's back or legs, giving a strong pine surge effect.

The strength of the jet water amount is controlled by the water amount switching valve 18.
Or, it is performed by controlling the opening degree of 20. That is, pressing the dorsal jet water amount switch _S16 or the leg side jet water amount changing switch _S18 once switches it to "strong," pressing it twice switches it to "medium," and pressing it three times switches it to "weak." If you press it again, it will return to "strong" again.

The air servo 26 controls the strength of the jet foam amount.
This is done by controlling the opening of the In other words, if you press the jet foam amount selector switch _S20 once, it will change to "strong".
, press twice to switch to "medium", and press three times to switch to "low". If you press it again, it will return to "strong" again. Press the dorsal jet switch S ₆ or foot jet switch S ₈ again to turn on the circulation pump 14.
stops.

By pressing both the dorsal side jet switch _S6 and the foot side jet switch _S8 , jet injection on the dorsal side and the foot side can be used together.

The setting conditions of "strong", "medium" and "weak" for the jet water amount and the setting conditions for "strong", "medium" and "weak" for the jet foam amount are stored in the sequence controller 100 each time, and are displayed on the liquid crystal display. displayed on panel 82.

In addition, in both the dorsal and leg side jet modes, as shown by the solid line arrows, some water is transferred from the circulation pump 14 to the air-water separation tank 50, the three-way valve 60, the filtration tank 56, the three-way valve 62, and the circulation pump. The water flows through 14 routes, and the bath water is filtered and washed. To control the strength of filtration, use the filtration strength switch S ₂₂
This is done by the operation of

Fall Mode When the dorsal fall switch _S10 or the foot fall switch _S12 is pressed, the dorsal or foot fall mode is selected, and the sequence controller 10 drives the fall mechanism C. That is, the circulation pump 14 is started and the on-off valve 28 or 30 is opened. Thereby, the water W in the bathtub is sucked through the suction port 12 and flows down into the bathtub 2 from the back-side fall nozzle 32 or the foot-side fall nozzle 34. dorsal fall switch
When S ₁₀ or the foot fall switch S ₁₂ is pressed again, the on-off valve 28 or
0 and stops the circulation pump 14, and when other modes are functioning, open/close valve 28
Alternatively, 30 is closed and the circulation pump 14 continues to be driven.

By pressing both the dorsal fall switch S ₁₀ and the foot fall switch S ₁₂ , it is possible to use both the fall fall on the dorsal side and the foot side.

It is also possible to use any two or all of the three modes: the air blow mode, the jet mode, and the fall mode. In this combined mode, each corresponding switch is operated in sequence.

Full Mode When the full mode switch _S26 is pressed, the full mode is selected, and the sequence controller 100 drives all three mechanisms, the air blow mechanism A, the jet mechanism B, and the fall mechanism C.

In this full mode, after pressing operation switch S ₂ to turn on the power, press air blow switch S ₄ ,
without pressing any of the dorsal jet switch S ₆ , foot jet switch S ₈ , dorsal fall switch S ₁₀ and foot fall switch S ₁₂ .
Full mode switch S ₂₆ following power on
The operation when pressing , and the above five switches S ₄
The behavior differs from what happens when you press the full mode switch _S13 after pressing one of ~ _S12 .

First, the operation when the full mode switch _S26 is pressed without pressing any of the five switches _S4 to _S12 will be explained.

In this case, the sequence controller 100
is the initial condition in the program,
Set the air blow water volume to ``strong,'' the dorsal and leg side jet water volumes to ``medium,'' and the dorsal and foot side jet foam volumes to ``strong.'' These initial conditions are then displayed on the liquid crystal display panel 82. The reason for setting the jet water volume on both the dorsal side and the foot side to "medium" is that if it is set to "strong", the capacity of the circulation pump 14 will be insufficient.
This is because, in the end, the amount of jet water tends to be insufficient and the circulation pump 14 is overloaded.

According to the above initial conditions, the sequence controller 100 drives the air pump 4 to "strong", switches the water volume switching valves 18 and 20 to "medium", switches the air servo 26 to "strong", and operates the on-off valve 28 , 30 are switched to "open" to drive the circulation pump 14.

Next, any one of the five switches S ₄ to S ₁₂
After one or more is pressed, the full mode switch
Explain what happens when you press S ₂₆ .

The sequence controller 100 stores the air blow water volume, dorsal jet water volume, foot jet water volume, dorsal jet foam volume, and foot jet foam volume that were set before the full mode switch _S26 was pressed. When the full mode switch _S26 is pressed, the sequence controller 100 reads out the previous setting conditions and sets each section accordingly. However, for the same reason as mentioned above, if the dorsal side jet water amount and foot side jet water amount were set to "strong" as the previous setting conditions, each is set to "medium". However, the display on the liquid crystal display panel 82 is "strong".

According to the immediately preceding setting conditions, the sequence controller 100 controls the phase of the air pump 4, the opening degree of the water volume switching valves 18 and 20, and the opening degree control of the air servo 26, as well as controlling the opening degree of the on-off valves 28 and 30. is opened, and the air pump 4 and circulation pump 14 are driven.

Regardless of whether or not the full mode switch S ₂₆ is pressed immediately after the start of operation, the amount of air blow water, the amount of jet water on the dorsal side or leg side, and the amount of jet foam on the dorsal side or leg side can be adjusted using the corresponding switch. It is also possible to change it by operation.

Furthermore, if a large-capacity circulation pump 14 is installed and there is no problem of insufficient capacity, the jet water volumes on both the dorsal side and the leg side may be set to "strong" in the full mode.

Backwash mode When the wash switch _S24 is pressed, the backwash mode is selected and the circulation pump 14 is activated as shown by the dashed arrow.
Some of the water from the air short-circuits the water separation tank 50 and is discharged to the outside via the three-way valve 62, the filtration tank 56, the three-way valve 60, and the drain pipe 64,
Backwashing is performed.

In the above embodiment, the jet mechanism B includes the dorsal side jet nozzle 22 and the leg side jet nozzle 2.
4, and the fall mechanism C has a dorsal fall nozzle 32 and a foot fall nozzle 34, but the present invention is not limited to this, and both the jet mechanism B and the fall mechanism C have , the dorsal side, or the foot side.

<Effects of the Invention> According to the present invention, no matter what the current status of the bathtub system is, it is always possible to operate in a single and identical full mode without having to recognize the situation or decide which switch to operate. Just by operating the switch, the air blow mechanism, jet mechanism, and fall mechanism can all be operated simultaneously to operate the full mode, which has the effect of improving operability when selecting the full mode. . Moreover, even if you press the full mode switch, the full mode operation will be performed under different conditions depending on the situation immediately before, so you can obtain different mercer effects depending on the full mode operation. . In particular, when transitioning from a single-mode functional state to a full-mode functional state,
The transition becomes smooth and the pine surge effect on the bather can be maintained constant, so the bather does not feel uncomfortable.
