Description

TECHNICAL FIELD The present invention relates to a bubble generating bath.

(B) Conventional technology Conventionally, there are bubble generation bathtubs that generate bubbles in the bath water and have a massage effect by the bubbles, a therapeutic effect using ultrasonic waves when the bubbles burst, and fatigue recovery. , A circulation pump is provided outside the bathtub to circulate the bathwater, the air is sucked into the circulating bathwater, and air is ejected into the bathtub together with the bathwater to generate bubbles in the bathwater.
When a plurality of hot water and air jets are provided, the circulating hot water discharged from a single circulation pump is branched so as to be jetted into the bath from the plurality of jets.

(C) Problems to be Solved by the Invention However, with one circulation pump, although the strength of bubble generation from all of the jets can be adjusted simultaneously, the strength of bubble generation from each of the jets can be adjusted. , It was not possible to adjust it individually according to the user's preference.

(D) Means for Solving the Problems The present invention provides a bubble-generating bath that is provided with a plurality of jets in a bath and is configured to generate bubbles at the same time when the bath is jetted from the jets. The circulation pumps installed outside the bathtubs are connected to each other via the bathwater return pipes,
It is intended to provide a bubble-generating bath having a bath hot water suction pipe interposed between the circulation pump and the bottom of the bath.

(E) Action / Effect In the present invention, since it is configured as described above, it is possible to dispose a circulation pump for each jet port and control each circulation pump individually. You can enjoy the comfortable bathing in the bubble bath by adjusting the bubble generation intensity from each jet individually.

(F) Embodiments An embodiment of the present invention will be described in detail with reference to the drawings. In FIGS. 1 and 2, (A) shows a bubble-generating bath, and the bath (A) has a collar with a constant width on the periphery. Forming an edge portion (1), and a controller (a) is arranged at a predetermined portion of the edge portion (1).

In addition, a plurality of jet ports (5) are provided in the bubble generation bath (A).
And a bubble generator (E) in communication with each of the jet outlets (5). The device (E) includes a circulation pump (B), a bathtub (A), and a pump. It is composed of a bath water circulation pipe (C) interposed between (B) and (B).

That is, the bath hot water circulation pipe (C) is a bath hot water suction pipe (C-1) for sending the bath hot water from the bubble generating bath (A) to the circulation pump (B), and the bath hot water circulation pipe (C) is the same as the bath (A). ) To send the hot water in a jet shape to the hot water return pipe (C
-2).

The suction pipe (C-1) has one end opened at the bottom of the bubble generation bath (A) so that the circulating pump (B) sucks the hot water.

The bath hot water return pipe (C-2) has one end communicating with the discharge port of the circulation pump (B) and the other end communicating with the jet port (5) opened at the bottom of the bubble generating bath (A).

Then, the bath water recirculation pipe (C- near the jet port (5)
The intake pipe (4) is separately connected to 2),
Therefore, the bath water in the bathtub (A) is sucked from the bathwater suction pipe (C-1) by the circulation pump (B) and is jetted from the jet port through the bathwater reflux pipe (C-2). At this time, the air is forcibly sucked from the intake pipe (4) communicating with the vicinity of the jet port (5) by using the negative pressure of the bath hot water flow, and thus sucked and mixed in the hot bath water. The air becomes bubbles and is ejected from the ejection port (5) together with the bath water.

The rotation speed of the circulation pump (B) is controlled by the frequency converter (30) (FIG. 5) provided in the control device (8) connected to the controller (a) described later, and the ejection port (5) It is possible to adjust the strength of the jet of circulating bath water from).

Further, a bubble control valve (6) is connected to the base end of the intake pipe (4) so as to adjust the bubble depending on the amount of intake air. It is arranged on the controller (a) at the edge (1).

Therefore, the controller (a) is operated to adjust the strength of the jet of the circulating bath water and the amount of bubbles mixed in the bath water to control the strength of bubble generation in the bubble generation bath (A). Can be adjusted.

Then, the air bubble generator (E) is connected to the two foot-side jet outlets (2) and the back-side jet outlets (3) that are opened at the front and rear lower portions of the bubble generating bath (A), and a total of four bubbles are formed. The circulating bath water and bubbles are ejected from the ejection ports (2) and (3) into the bubble generation bath (A).

As shown in FIG. 3 and FIG. 4, the controller (a) forms a slightly raised controller table (a-1) on the edge portion (1) of the bubble generation bath, and the controller (a-).
1) The handle (6 ') of the bubble control valve (6) is arranged above, and each valve (6) is hung vertically from the edge portion (1) so as to extend from each jet port (2) (3). The amount of bubbles ejected into the bubble generation bath (A) can be adjusted.

Further, an optical switch (7) for controlling the rotation speed of each circulation pump (B) is arranged at substantially the center of the controller (a).

As shown in FIGS. 3 and 4, the optical switch (7) includes a water-repellent membrane (11) that also serves as an operation display, a casing (13) to which the membrane (11) is attached, and the same casing. It is composed of a pressing body (14) built in (13).

The pressing body (14) is provided with a blocking plate (16) that moves in the vertical direction by pushing the central portion of the pressing body (14), and the blocking plate (16) is provided on both sides of the blocking plate (16). When a bather presses the pressing body (14) of the optical switch (7) by providing a light projecting part (17) and a light receiving part (18) that can be blocked / conducted by movement, the blocking plate (16) causes an optical fiber. The light conduction of (20) and (21) is cut off, and this is output to the control device (8) as an ON signal of the optical switch (7).

When the above signal is input, the control device (8) determines the duration of the signal and controls the driving / stopping of each circulation pump (B) and the rotation speed to adjust the jet strength of the circulating bath water.

That is, as shown in FIG. 5, each circulation pump (B)
The frequency converter (30) is interposed in the drive circuit (F) of the device, and the photoelectric conversion element (32) is provided in the controller (8) to convert the optical signal from each optical switch (7) into an electric signal. Then, the output of the same element (32) is input to the integration circuit (33),
A voltage proportional to the duration of the above signal is output to the VF conversion element (34), and the output of the element (34) is input to the trigger terminal (31) of the frequency converter (30), thereby the circulation pump. The frequency of the AC voltage that drives (B) is controlled.

 (35) in the figure is a drive power supply.

The integrating circuit (33) is configured to be reset when the output voltage is saturated.

Therefore, the frequency becomes higher as the time that each optical switch (7) is pressed becomes longer, and if it continues to be pressed beyond the upper limit of the same trigger frequency, the output to the trigger terminal (31) stops once. If the button is pressed continuously, a cyclic control operation is performed in which the trigger frequency is gradually increased from the output stopped state, and the jet strength of the circulating bath is adjusted.

In the present invention, because of the above-described configuration, the circulation pumps correspond to the respective ejection ports, and it is possible to individually control the respective circulation pumps. Individually adjust the strength of bubble generation from
You can enjoy bathing in the comfortable bubble bath.
