Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bubble bath which blows air bubbles into a bath from a bubble blowing nozzle provided on the bottom of the bath.

[0002]

2. Description of the Related Art A bubble tub is usually provided with four to twelve bubble jet nozzles on its bottom surface, depending on the size of the bath tub. Supply air from the source to the bubble jet nozzle through the pipe,
In this method, air is jetted out of a bubble jet nozzle into hot water in a bathtub in a bubble state, and muscles and skin are massaged by the bubble. An example is disclosed in Japanese Patent Application Laid-Open No. Hei 5-137767.

[0003] In such a bubble bath, it is desirable that the air bubbles are emitted from all of the bubble jet nozzles in a uniform manner (strength). There is a problem that arises. In particular, when the strength of the bubbles is weakened, uneven fumes are likely to occur. For example, in a bubble bath having eight bubble jet nozzles, the strength of the bubbles is reduced to “weak” among three stages of weak, medium, and strong. As a result, uneven fumes may be generated such that bubbles are emitted from the six bubble ejection nozzles but not from two.

Therefore, as a result of further investigation, when the air supply is started at "strong" at first, bubbles are ejected almost uniformly from all the bubble ejection nozzles, and then switched to "weak" or "medium" after 5 to 10 seconds, for example. However, it was found that bubbles continued to be ejected almost uniformly from all the bubble ejection nozzles. This phenomenon is that when air supply is started at "strong", an "air path" is created in the bubble ejection nozzle, and then the "air path" is opened even if the strength of the bubble is reduced to "weak" or "medium" It is considered that the fumarole will no longer occur because it remains as it is.

On the other hand, when the supply of air is started at "weak", the output of the bubble is discharged to the tip of the bubble discharge nozzle due to the difference in the position of the bubble discharge nozzle and the resistance of the bubble discharge nozzle and the piping. "Air way" that cannot overcome such water pressure and surface tension
It is considered that fumarole unevenness occurs due to the failure.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and has been made in view of the results of the above-mentioned investigations and examinations. It is an object of the present invention to provide a bubble bath in which bubbles having a strength set first can be obtained after a certain time has elapsed after the start of air supply.

[0007]

In order to achieve the above object, the present invention provides a bath tub having a plurality of bubble jet nozzles mounted on a bottom surface thereof, and air supplied from an air supply source through piping. A bubble bath which is bubbled by a bubble blowing nozzle and blows out into the bathtub. The bubble bath has a control unit capable of switching the amount of air supplied from an air supply source to a plurality of stages. Even when the air volume is selected, control is performed such that air is supplied at the maximum air supply amount for a certain period of time, and after a certain time period, air is supplied at the first air supply amount.

(Operation) The air supply source is switched on to start air supply, and air supply is performed at a maximum supply amount for a certain period of time by a program incorporated in the control unit. An "air path" is created and uniform air bubbles are obtained. Then, after a certain period of time, the air supply amount is switched to the initially selected and set air supply amount (the air supply amount may be equal to or less than the maximum air supply amount). In the case of (1), bubbles at a desired supply amount set by all the bubble ejection nozzles are continuously ejected, and no unevenness of the ejection is generated.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory diagram showing a configuration of an embodiment of the present invention. As shown in FIG. 1, a bubble bath 1 has a plurality of bubble jet nozzles 3 attached to the bottom of a bath 2. Each of the bubble jet nozzles 3 has a large-diameter nozzle 3 for generating massage bubbles with large foam particles.
1, and a small-diameter nozzle 32 for generating a relaxed bubble having a small bubble particle is provided.

An air pump 4 (air supply source) is installed outside the bubble bath 1, and air generated by the air pump 4 is sent to a solenoid valve 5 through a pipe 60, and the air valve 4 will be described in detail below. As described above, after the air supply strength is switched to three levels of strong, medium, and weak, the air is separately supplied to the large-diameter nozzle 31 through the pipe 61 and to the small-diameter nozzle 32 through the pipe 62, respectively. A massage bubble is generated from the large-diameter nozzle 31, and a relax bubble is generated from the small-diameter nozzle 32.
It is designed to be sprayed into the bath. Table 1
Is the bubble ejection amount of the massage bubble and the relax bubble when the strength of the bubble (that is, the strength of the air supply) is switched among three levels of strong, medium, and weak.

[0011]

[Table 1]

Reference numeral 7 denotes a control unit. The control unit 7 can perform ON (operation) and OFF (stop) operations of the air pump 4,
It is possible to select and input the desired strength of the bubbles, strong, medium, and weak, to input the time for maintaining the strength of the bubbles at “strong”, and to start the operation in the control unit 7. After the elapse of the time of maintaining the pressure at “strong”, a program that can switch to the strength of the initially selected bubble is incorporated.

The solenoid valve 5 receives a signal generated by the control unit 7 in accordance with an input to the control unit 7 and
The operation to switch the supply air volume from the high, medium, and low is performed. The input to the control unit 7 and its operation can be performed by a bather operating the remote controller 8.

Next, the operation of the bubble bath 1 shown in FIG. 1 will be described with reference to FIGS. FIG. 2 is a flowchart of the operation in the bubble bath shown in FIG. Bubble tub 1
Prior to the use of the bath, the bather sends the remote control 8 to the control unit 7,
Select and enter the desired bubble strength (eg, "weak"). At this time, a time (for example, 5 seconds) for keeping the strength of the bubble at “strong” is input.

Next, when the start switch of the air pump 4 is turned on in S ₁ (S means “step”), the control unit 7
Determines “Yes” or “No” for “operation SW: ON?”. As a result, Y is selected by ON (Yes), the operation flow moves downward, and the air pump 4 is started.

The start switch of the air pump 4 is turned on.
In the case where no "operation SW:? ON" is determined as No respect, the flow of operation is moved to S _6, the air pump 4
Remains shut down.

[0017] The air pump 4 after start-up, in the next S ₂ "operation after the start within 5 seconds?" Whether it is determined, if it is not passed 5 seconds Y is selected, the flow of the operation is moved to S ₃ As a result, the solenoid valve 5 is in a strong position, and the bubble ejection nozzle 3 is supplied with the maximum supply amount. As a result, an “air path” is created in all the bubble ejection nozzles 3, and 100 l / min from the large-diameter nozzle 31 of the bubble ejection nozzle 3 and 7 to 7 from the small-diameter nozzle 32.
At 0 l / min, bubbles are ejected with uniform intensity. And flow of the operation returns to S _1.

[0018] In S _1, already operating SW is because it is turned ON, the flow of operation immediately proceeds to S _2. At this time, if I elapsed after start already above 5 seconds, since it is determined as No to "after start within 5 seconds?", The process proceeds to S _4, set in the first control unit 7 "weak" Is taken in,
Is switched solenoid valve 5 in S _5, the air supply of the "weak" is made through the pipe 61 and 62.

However, at this time, since the "air path" has already been formed in all the bubble ejection nozzles 3, massage bubbles and small diameters are emitted from the large-diameter nozzles 31 of the bubble ejection nozzles 3 at an ejection rate of 60 l / min. From the nozzle 32, the relaxing air bubbles are continuously ejected at an ejection amount of 30 l / min.

In the above example, the desired bubble strength is initially selected as "weak", but the same applies if "medium" is selected.

Although the embodiment of the present invention has been described above, the specific configuration is not limited to the above, and the present invention includes design changes and the like without departing from the gist of the present invention.

For example, in the above-described embodiment, the air supply amount from the air pump 4 is switched between strong, medium and weak by switching the solenoid valve 5, but by changing the rotation speed of the air pump 4, A structure in which the amount of air supplied to the bubble jet nozzle 3 is directly changed may be employed.

[0023]

As is apparent from the above description, according to the present invention, even if the air bubbles are first weakened and the engine is started, there is no unevenness in the air blowing between the air bubble jet nozzles. After a certain period of time has elapsed since the start, bubbles having the desired strength can be obtained, so that the bubble bath can be enjoyed comfortably.
