S ₁₂ and a liquid crystal display panel 19 are provided.
20 is a sequence controller configured with a microcomputer.

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

Pressing the operating switch _S1 activates the sequence controller 20.

Air Blow Mode When the air blow switch _S2 is pressed, the air blow mode is selected, and the sequence controller 20 starts the air pump 5. As a result, an air blow is performed on the water in the bathtub from the plurality of air blow nozzles 2 via the air blow piping 4 and the header 3 to envelop the whole body of the bather.

The strength of the air blow is controlled by controlling the phase of the air pump 5. Press the air blow amount switch S ₇ once to set it to "strong", press it twice to set it to "medium"
Press three times to switch to "low". If you press it again, it will return to "strong" again. Air blow switch S ₂
Press again to stop the air pump 5.

Jet mode When you press the dorsal jet switch _S3 or the foot jet switch _S4 , the sequence controller 20
starts the jet pump 9 and opens the water flow selector valve _V1 or _V2 . As a result, the water in the bathtub is sucked from the suction port 6 and is returned to the bathtub 1 from the back side jet nozzle 7a or the foot side jet nozzle 7b, but air is sucked into the back side jet nozzle 7a or the foot side jet nozzle 7b via the air servo 10. It becomes a jet water stream containing air and is ejected into the water in the bathtub.

The intensity control of the jet water amount is performed by controlling the opening degree of the water amount switching valve _V1 or _V2 . Press dorsal jet water volume switch _S8 or foot jet water volume switch _S9 once to switch to "strong", press twice to switch to "medium", and press three times to switch to "weak". If you press it again, it will return to "strong" again.

The strength of the jet foam amount is controlled by controlling the opening degree of the air servo 10. Pressing the jet foam amount changeover switch _S10 once changes it to "strong", pressing it twice changes it to "medium", and pressing it three times changes it to "low".
If you press it again, it will return to "strong" again. Pressing the dorsal jet switch _S3 or foot jet switch _S4 again stops the jet pump 9.

Note that by pressing both the dorsal side jet switch _S3 and the foot side jet switch _S4 , jet jets on the dorsal side and the foot side can be used together.

In this jet mode, as shown by the solid arrow, some water flows from the jet pump 9 through the path of the steam/water separation tank 11, the three-way valve 16, the filtration tank 14, the three-way valve 17, and the jet pump 9, thereby filtering and cleaning the bathtub water. will be held. The strength of filtration is controlled by operating a filtration strength switch _S11 .

Backwash Mode When the wash switch _S12 is pressed, the backwash mode is selected, and some of the water from the jet pump 9 short-circuits the steam-water separation tank 11, causing the three-way valve 17, the filtration tank 14, It is discharged to the outside via the three-way valve 16, and the filtration tank 14 is backwashed.

Full mode When you press dorsal fall switch S ₅ or foot fall switch S ₆ , the sequence controller 20
starts the jet pump 9 and opens the water flow selector valve _V3 or _V4 . As a result, the water in the bathtub is sucked from the suction port 6, and the water in the bathtub 1 is sucked from the back side full nozzle 8a or the foot side full nozzle 8b.
is washed away. When the dorsal fall switch _S5 or foot fall switch _S6 is pressed again, the jet pump 9 will stop.

Note that by pressing both the dorsal fall switch _S5 and the foot fall switch _S6 , it is possible to use both the dorsal fall flow and the foot fall fall flow.

Note that it is also possible to use the air blow mode, the jet mode, and the fall mode in combination.

<Problems to be solved by the invention> In the conventional bathtub system described above, the intensity of air blow and jet ejection was determined by the number of times the switch was pressed, so when changing the intensity, it was necessary to press the switch. I had to push it again.

By the way, there are several specific patterns of intensity change for the pine surge effect that are typically preferred. Conventionally, in order to achieve this preferred intensity change pattern, it was necessary to press the switch again as described above, which meant that the bather was forced to perform a cumbersome operation. Further, depending on how the bather operates, it may not always be possible to realize the desired intensity change pattern.

The present invention was devised in view of the above circumstances, and an object of the present invention is to enable a specific intensity change pattern to be quickly set by a single switch operation.

<Means for solving the problem> In order to achieve the above purpose, the present invention
It has the following structure.

The bathtub system of the present invention includes a bathtub, an air blow nozzle, an air pump, an air blow switch, an air blow foam amount selection switch, a sequential menu switch, and a sequence controller, wherein the air blow nozzle is The air pump is connected to the air blow nozzle via piping to forcefully send air to the air blow nozzle, and the air blow switch is used to start and stop the air pump. The air blow foam volume changeover switch is used to adjust the capacity of the air pump through setting operations, the sequential menu switch is used to specify a specific pattern of foam volume change, and the sequence controller is used to control the air blow switch. Controls the start and stop of the air pump according to the on/off operation of the air pump, and controls the capacity of the air pump stepwise according to the selection operation of the air blow foam amount selection switch, and
By turning on the sequential menu switch, the capacity of the air pump is controlled to change automatically over time in accordance with a specific pattern.

<Operation> The operation of the above structure of the present invention is as follows.

In addition to the mode in which the amount of foam ejected from the air blow nozzle into the water in the bathtub is changed in stages by setting the air blow foam amount selection switch, there is also a mode that automatically changes the amount of foam over time by operating the sequential menu switch. It is possible to select a mode in which a specific pattern of changes in the amount of bubbles is realized by changing the amount of foam to a specific pattern. In particular, in order to achieve the latter specific pattern of changing the amount of foam, there is no need for the troublesome operation of pressing the air blow switch over and over again as in the conventional example, and it is now possible to simply press the sequential menu switch. With simple operations, you can quickly and automatically change the amount of foam in a specific pattern without making any operational errors.

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

FIG. 1 is a schematic diagram of a bathtub system according to an embodiment of the present invention.

In the figure, 1 is a bathtub, 2 is an air blow nozzle, 3 is a header, 4 is an air blow pipe, 5 is an air pump, 6 is a suction port, 7a and 7b are jet nozzles on the back and feet, and 8a and 8b are jet nozzles on the back and feet. side fall nozzle, 9 is a jet pump, V ₁ to _{V 4} are water flow switching valves, 10 is an air servo, 11 is a steam/water separation tank, 12 is a water level switch, 13 is an air bleed valve, 14 is a filtration tank, 15 is an air bleed valve , 16 and 17 are three-way valves, 18 is a remote control operation section, and 20 is a sequence controller.

FIG. 2 is a front view of the remote control operation section. 19
is the liquid crystal display panel, S ₁ is the operation switch, S ₂ is the air blow switch, S ₃ is the dorsal jet switch, S ₄
is the foot side jet switch, S ₅ is the dorsal side fall switch, S ₆ is the foot side fall switch, S ₇ is the air blow foam volume switch, S ₈ is the dorsal jet water volume switch, and S ₉ is the foot jet water volume switch. Switch,
_S10 is a jet foam amount changeover switch, _S11 is a filtration strength/weakness switch, and _S12 is a cleaning switch.

Since the above configuration is similar to the conventional example explained in FIGS. 9 and 10, the same reference numerals are given here, and the explanation will be omitted.

The remote control operation unit 18 includes each of the above switches S ₁
In addition to _S12 , a first sequential menu switch _MS1 and a second sequential menu switch _MS2 for air blowing are provided.
The first sequential menu switch MS ₁ is
This is for specifying the amount of bubbles ejected from the air blow nozzle 2 into the water in the bathtub to one specific pattern that is preferable for the pine surge effect. The second sequential menu switch _MS2 is for specifying a specific pattern that repeats the specific pattern specified by the first sequential menu switch _MS1 a plurality of times.

Next, the operation of the sequential menu mode in the bathtub system of this embodiment will be explained.

Press the operation switch S ₁ to activate the sequence controller 20, and then press the air blow switch S ₂ .
Press to start air pump 5. Regardless of whether the air blow intensity is set to “strong,” “medium,” or “weak” using the air blow foam amount selection switch _S7 ,
By pressing the first sequential menu switch MS ₁ , the sequence controller 20
The phase of the air pump 5 is controlled so that the capacity of the air pump 5 changes according to a specific pattern shown in FIG. In other words, as time passes, the air blow strength changes from "weak" → "medium" → "strong" → "medium" →
Control to automatically change in stages such as "weak".

By pressing the second sequential menu switch MS ₂ , the sequence controller 20
controls the phase of the air pump 5 so that the capacity of the air pump 5 changes according to a specific pattern shown in FIG. In other words, "weak" → "medium" → "strong"
A set of stepwise changes from → "medium" → "weak" is controlled so that a specific pattern is repeated three times.

Note that if either the first or second sequential menu switch MS ₁ or MS ₂ is pressed again, the sequence controller 2
0 may be configured such that the intensity of the air blow and the intensity of the jet jet on the dorsal side and the foot side are changed in accordance with a specific pattern shown in FIG. 5 or 6 in terms of both the amount of water and the amount of bubbles. In this case, to control the intensity of jet jetting, the jet pump 9 is activated and the opening degrees of the water volume switching valves V ₁ and V ₂ and the air servo 10 are controlled. Then, when the sequential menu switches MS ₁ and MS ₂ are pressed once again, the configuration is such that the pattern returns to that of FIG. 2 or 3.

In order to achieve such a pattern in the conventional example, air blow foam volume selection switch S ₇ , dorsal jet water volume selection switch S ₈ , leg side jet water volume selection switch S ₉ and jet foam volume selection switch are required.
S ₁₀ must be repeated many times, but
When controlling as described above using sequential menu switches MS ₁ and MS ₂ , only one operation is required.

Various patterns other than those described above can be considered as the patterns specified by the first or second sequential menu switches MS ₁ and MS ₂ . For example, the first sequential menu switch MS ₁
As shown in Figure 7, when you press , both the air blow strength and the jet ejection strength on the dorsal side and foot side change from "weak" → "medium" → "strong" → "medium".
→ "Weak" and at the same time, a pattern in which the fall is made to flow down from the dorsal and foot side fall nozzles 8a and 8b at a constant intensity is also preferable for the pine surge effect. In this case, the first
Pressing the sequential menu switch MS ₁ again will switch to a pattern that fixes the air blow and dorsal and foot side jet jets to "strong" while leaving the falling flow as is, as shown in Figure 8. It is also preferable.

Although not shown, when the second sequential menu switch MS ₂ is pressed, the jet ejection on the dorsal side and foot side is changed from "weak" to "medium" to
Control may be performed such that a stepwise change from "strong" to "medium" to "weak" is repeated three times.

Specific patterns include not only the three combinations of "strong,""medium," and "weak," but also the two combinations of "strong" and "weak."
It may be a combination of two levels, or a combination of four or more levels. Furthermore, instead of changing stepwise, it may be changed continuously. In any case, by designing the program in the microcomputer that constitutes the sequence controller 20, many desirable specific patterns can be realized.

Other operations are the same as those of the conventional example, so explanations will be omitted.

<Effects of the invention> According to the invention, the operation can be performed quickly and without mistakes by simply pressing the sequential menu switch, without having to perform the troublesome operation of pressing the air blow switch many times as in the past. The amount of foam spouted into the bathtub can be automatically changed over time under a specific pattern that favors the pine surge effect.
