Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to the structure of an air intake pipe in a bath with a bubble generator.

[0002]

[Prior art]

 Conventionally, in the structure of the air intake pipe used in a bath with a bubble generator of this type, one end of a pipe with a uniform thickness is attached to a bubble-only circulation fitting that blows air into the water in the bath, and the other end is attached. Was installed on the opposite side of the wall where the bathroom remote control was installed, or was installed as an air intake in the bathtub.

When a bather operates the bathroom remote controller, the bubble generation pump operates to circulate the water in the bathtub through the bubble circulation pipe. The air sucked from the inlet was bubbled into the bath with the circulated water.

[0004]

[Problems to be solved by the device]

 However, in this conventional device, when the air from the air intake pipe is mixed with the water in the bath tub that has been circulated by the Venturi effect in the bubble exclusive circulation fitting, and when it is made into bubbles and blows out together into the bath, The noise when water collided or air bubbles burst was leaking as noise from the air intake of the air intake pipe.

Therefore, when the air intake is installed behind the bathroom remote controller with the wall of the bathroom separated, it becomes noise to the inside of the house, and when the air intake is installed in the bathroom or the bathtub, it is against the bather. It was noisy and made me feel uncomfortable.

[0006]

[Means for solving problems]

 This invention focuses on this point and solves the above-mentioned drawbacks. In particular, the configuration is provided with a bubble generator that has an air intake pipe and discharges the air sucked from the air intake pipe as water bubbles into the water in the bathtub. In a bath, one end is attached to the air bubble circulation device installed in the bathtub, and a silencer with a larger diameter than the air intake pipe is provided in the air intake pipe line that inhales air from the opening at the other end. is there.

[0007]

[Action]

 By providing a muffler with a larger diameter than the air intake pipe in the air intake pipe that has one end attached to the bubble generator, the noise generated when the air bubbles into the bubble generator and blows out is small. When propagating from the intake pipe to the large-diameter silencer, or conversely from the large-diameter silencer to the small-diameter air intake pipe, part of the noise propagating inside the pipe is reflected or transmitted at the discontinuity surface. By doing so, the traveling wave and the reflected wave of the sound interfere with each other to attenuate the sound and reduce the noise.

[0008]

【Example】

 Next, an air intake pipe in a bath with a bubble generator according to the present invention will be described with reference to a preferred embodiment shown in the drawings. 1 is a water heater with a built-in bath kettle, which has a bubble generating pump 2 and a heat exchange unit (not shown) built therein, and the bubble generating pump 2 circulates water in the bathtub 3 and a bubble circulating pipe 4 A bath circulation pipe 5 is connected to heat water in the heat exchange unit and circulate it in the bathtub 3.

A bubble generator 6 is composed of a bubble generation pump 2, a bubble circulation pipe 4, a bubble-only circulation fitting 7 and an air intake pipe 8. The bubble-only circulation fitting 7 keeps the water in the bath 3 from flowing. It is sucked into the water heater 1 with a built-in bathtub via the foam circulation pipe 4, and is pressurized by the bubble generation pump 2 again through the bubble circulation pipe 4 to the inside of the bath 3 from the jet port 9 of the bubble exclusive circulation fitting 7. Blow out to. At this time, one end of the bubble circulation pipe 4 having a nozzle-like tip is located inside the ejection port 9, and one end of the air intake pipe 8 is located around it, so that air is sucked in by the Venturi effect and bubbles are generated. The air is blown out into the bathtub 3 in the form of bubbles together with the water circulated from the ejection port 9.

Reference numeral 10 denotes a bath circulation fitting, which sucks the water in the bathtub 3 into the water heater 1 with a built-in bath kettle through the bath circulation pipe 5, and circulates the water circulated in the heat exchange section in the water heater 1 with a built-in bath kettle. After heating, the water is returned to the bathtub 3 through the bath circulation pipe 5 again.

Reference numeral 11 denotes a bathroom remote controller. By operating the remote controller, various settings such as additional heating of the bath, setting of the temperature of hot water, turning on / off of blowing bubbles and setting the amount of blowing bubbles can be operated. Reference numeral 12 denotes a rear box in which one end of the air intake pipe 8 is attached, and the air sucked from the air intake 13 at the tip of the air intake pipe 8 in the rear box 12 has a large-diameter silencer 14 And is guided into the bubble-only circulation fitting 7 to be bubbled and blown into the bath tank 3.

Next, the operation of this embodiment will be described. When the bather operates the bathroom remote controller 11 to turn on bubble generation and set the amount of air blown out, the bubble generation pump in the water heater 1 with a built-in bathtub operates, sucking the water in the bathtub 3 from the bubble-only circulation metal fitting 7, After passing through the bubble circulation pipe 4, the bubble generation pump 2 in the bath water heater 1 is adjusted, the pressure is adjusted so that the bubbles have the strength set by the bathroom remote control 11, and the bubble circulation pipe 4 again. And blows out from the spout 9.

Inside this ejection port 9, there is one end of a bubble-type circulation pipe 4 having a nozzle-like tip, and one end of an air intake pipe 8 is located around this, and the circulating water is discharged from the ejection port 9. When it is blown out, the air is sucked in due to the Venturi effect and mixed with water to form bubbles, which blows out into the bathtub 3 together with the water.

Air is sucked from the air intake 13 at one end of the air intake pipe 8 installed in the rear box on the back side of the bathroom remote controller 11 and blows out in the form of bubbles from the bubble-only circulation fitting 7. The sound when mixed with water or when some of the bubbles burst is transmitted through the air intake pipe 8 and leaks as noise from the air intake 13.

Therefore, by providing a large-diameter silencer 14 in the middle of the air intake pipe 8, when the small-diameter air intake pipe 8 propagates to the large-diameter silencer 14, and vice versa. When propagating from the air to the small-diameter air intake pipe 8, the sound is reflected or transmitted by the discontinuous surface, the traveling wave of the sound and the reflected wave interfere with each other, and the noise is attenuated and becomes small. In the present embodiment, the bubble generating pump 2 is built in the bath water heater 1 with a built-in bath. However, the present invention is not limited to this, and the bubble generating pump 2 alone may be used. Further, in the present embodiment, the air intake 13 is provided in the back box 12 behind the bathroom remote controller 11, but the invention is not limited to this, and it may be provided in the bathroom, the bathtub 3, or the like.

Further, although the muffling section 14 is provided in the middle of the pipe line in the present embodiment, it may be provided at the end of the air intake 13 as shown in FIG. In the embodiment of FIG. 2, air is sucked into the bubble-only circulation fitting 7 from the air inlet 13 at the tip of the air intake pipe 8 through the four holes on the bottom surface of the muffling section 14, and is generated from the bubble-only circulation fitting 7. The generated noise is propagated from the air intake pipe 8 having a narrowed tip to the air intake 13 into the muffling section 14, and is attenuated and propagated outside from the four holes on the bottom surface of the muffling section 14.

[Effect of device]

 In short, the invention is a circulation metal fitting for exclusive use of bubbles, which has an air intake pipe and has a bubble generator that discharges the air sucked by the air intake pipe as water bubbles into the water in the bathtub. The muffler is attached to the air intake pipe that draws in air from the opening at the other end, and a muffling part with a diameter larger than that of the air intake pipe is provided in the air intake pipe so that when air bubbles are generated in the bathtub The leaking noise is attenuated and made smaller, which allows quiet air bubbles to be generated without disturbing the bather and other people in the house.
