Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a bubble bathtub device for blowing bubbles into a bathtub.

[Prior art] In the case of a bubble bath device, water (usually hot water) is extracted from a circulation outlet of a bathtub, and returned to the bathtub via a circulation pump and a nozzle, and air is mixed into the water flow at the nozzle. The system is configured so that air bubbles are ejected into the bathtub as bubble-mixed water. An air pipe is connected to this nozzle, and a manual valve is provided at the tip of the pipe. This valve is usually provided on the handrail of the bathtub. When the opening degree of this valve is increased, the amount of air caught in the water flow at the nozzle increases, and the amount of bubbles ejected into the bathtub also increases. Conversely, when the opening degree of this valve is reduced, the amount of bubbles is reduced.

[Problems to be solved by the invention] In conventional bubble bathtub devices, the amount of circulating water is constant when the circulation pump is operated. For this reason, regardless of the amount of bubbles ejected, the speed of bubble ejection is constant and cannot be adjusted as desired by the bather, which is inconvenient.

In addition, in conventional bubble bath equipment, the opening degree of the air flow rate control valve was manually adjusted, so for example, after operating the switch that activates the circulation pump, There was an inconvenience in that it was necessary to reach out and manually operate the valve, which took time and effort.

[Means for Solving the Problems] The bubble bathtub device of the present invention includes a circulation flow path that extracts water from a circulation outlet of a bathtub and returns it to the bathtub from a circulation return port, and a pump provided in the flow path. A bubble bathtub device including a nozzle provided at the circulation return port and for mixing air from the air pipe into the circulating water, further comprising: an air flow rate regulating valve provided in the air pipe; a first electric drive device for adjusting the opening degree of the air flow rate control valve; a circulating water rate control valve provided in the circulation flow path; and a second electric drive device for adjusting the degree of opening of the circulating water rate control valve. A device, a controller that controls the first electric drive device and the second electric drive device, a switch that provides a control signal to the controller, and a display that displays the bubble ejection operation from the nozzle are integrally provided. It is characterized by the following: a controller panel with a

[Function] In the bubble bath device of the present invention, both the amount of circulating water and the amount of mixed bubbles can be adjusted by operating a switch. Moreover, the switch on the control panel can be operated while checking the air bubbles ejected from the nozzle on the control panel surface. Therefore, both the amount and speed of bubbles ejected into the bathtub can be easily adjusted.

The pipe 46 from the pump 42 is connected to the pipes 64, 6
6 and 67, and the pipe 64 connects to the nozzle 22a via a circulating water amount control valve 68 and a pipe 70.
It is connected to the. Piping 66 is the circulating water flow control valve 7
2 and piping 74 to the nozzle 18a. The pipe 68 is connected to the nozzle 26a via a circulating water amount control valve 76 and a pipe 78.

The nozzle 32 is connected to an air pump 82 via an air pipe 80.

Air pipes 16b to 26b are connected to the nozzles 16a to 26a, respectively, and air flow control valves 1 are installed in the middle of these air pipes 16b to 26b.
6c to 26c are provided. These air flow control valves 16c to 26c are configured to be driven by stepping motors 16m to 26m, respectively, as electric drive devices.

The circulating water amount control valves 54, 58, 60, 68,
The openings of the openings 72 and 76 can be adjusted by stepping motors serving as electric drive devices. Note that this stepping motor is designated by the same reference numeral as those of the valves, but with an "m" added thereto.

The stepping motors for driving the circulating water amount control valve and the air flow rate control valve are all controlled by a controller 90. This controller 90 receives operation signals from a control panel 92 and outputs signals to each stepping motor. Further, this controller 90 outputs a signal to a control panel 92 to display its operating state. Note that the circulation pumps 40, 42
The operation is also controlled by a control signal from the controller 90.

Although not shown, the pipes 36 and 44 and the pipes 38 and 46 are connected by return pipes each having a throttle valve, and the excess amount of water discharged from the pumps 40 and 42 is transferred to the upstream pipes 36 and 46. 38
It is configured to return to

In the bubble bathtub device configured in this way,
When the pump 40 is operated, water in the bathtub 10 is discharged through the circulation outlet 28 and the pipes 36 and 44.
Then, it is discharged from the circulation return ports 20, 16, 24 according to the opening degrees of the valves 54, 58, 60. On this occasion,
Air bubbles are mixed into the discharged water according to the opening degrees of the air flow rate control valves 20c, 24c, and 16c, and the water is ejected into the bathtub 10 as bubbly mixed water. In this case, the desired amount of circulating water can be adjusted by adjusting the opening degrees of the circulating water amount control valves 54, 58, and 60 using stepping motors 54m, 58m, and 60m.
In addition, the opening degrees of the air flow control valves 20c, 24c, 16c are controlled by stepping motors 20m, 24m, 16c.
By adjusting m, the amount of bubbles mixed can be adjusted to a desired amount.

When the pump 42 is operated, the circulation return ports 18, 22, 26 are opened in the bathtub 10 in exactly the same manner.
Circulating water can be spouted from. and,
By adjusting the opening degrees of the air flow control valves 18c, 26c, and 22c, the amount of air mixed in can also be adjusted to a desired amount.

In this way, according to this embodiment, not only the amount of air mixed in but also the bubble ejection speed can be adjusted as desired. In particular, in this embodiment, the left and right halves of the bathtub are divided into separate systems (pump 40 system and pump 42 system), so that only the left half or the right half of the bathtub can blow out bubbles. A bubble blowing operation is also possible.

In this embodiment, when the air pump 82 is further operated, air bubbles can be blown from the bottom of the bathtub 10, and a bubble bathing operation can be performed so that the entire body of the user of the bathtub 10 is covered with air bubbles.

In this embodiment, as shown in FIG. 2, a model of the bathtub 10 and the posture of the user bathing in the bathtub 10 are shown on the control panel, and bubbles are ejected from which nozzle. Are you there?
The LED display allows you to check the operating status of the bubble bath at a glance, which is extremely convenient. The control panel 92 is provided with switches for performing a series of controls as shown in the figure.

In the embodiment described above, a stepping motor is used as the electric drive device for the valve, and by doing so, the opening degree of the valve can be controlled accurately and in small steps within a predetermined width. However, various other electric drive devices may also be used in the present invention.

[Effects] As described above, according to the bubble bathtub device of the present invention, both the amount of circulating water and the amount of mixed air bubbles can be easily adjusted by operating a switch while looking at the display on the control panel, and the amount of air bubbles spouted into the bathtub can be easily adjusted.
