Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sound deadening structure for a bathroom equipped with a bubble generating bath.

[0002]

2. Description of the Related Art Conventionally, as an example of an air bubble generating bathtub installed in a bathroom, a bath hot water circulation passage consisting of a water absorption pipe and a water supply pipe is provided between a bath body and a circulation pump to supply water. A structure in which the end of the pipe is opened in the body of the bathtub to serve as a jet nozzle, and an air intake part is connected in communication with the water supply pipe so that bath water containing bubbles can be jetted into the bathtub body from each jet nozzle. There is.

In such a bubble generating bath, there is an adverse effect that the sound of the bath water is blown out, the sound of bubbles explodes, etc., and the inside of the bathroom is noisy and the noise leaks to the outside to disturb the neighborhood.

[0004] As a means for eliminating such an adverse effect,
There is a device described in Japanese Utility Model Laid-Open No. 2-71387. In the device, a sound absorbing material is attached to the entire inner wall surface of a bathroom, and the sound absorbing material absorbs the above noise. For noise leaking to the outside from an opening such as a window, a grating made of a sound absorbing material is inserted into the opening to absorb the noise.

[0005]

However, in the above prior art, since the sound absorbing material is attached to the entire inner wall surface of the bathroom,
It requires a large amount of sound absorbing material, which complicates the wall surface structure and narrows the internal space of the bathroom.

[0006]

According to the present invention, a bath hot water circulation passage consisting of a water absorption pipe and a water supply pipe is provided between a bath body and a circulation pump, and an air intake portion is connected to the water supply pipe. In a bathroom equipped with a bubble-generating bath that is capable of spouting hot water mixed with bubbles into the body of the bath, a partition is stretched below the ceiling wall of the bathroom with a fixed space between them. A silencer for a bathroom equipped with a bubble-generating bath characterized in that a predetermined gap is provided between a peripheral edge of the bathroom and a side wall of the bathroom to attenuate noise in a space formed by a lower surface of the ceiling wall and an upper surface of the partition wall. It is intended to provide structure.

The motor M that drives the pump P is connected.

As shown in FIGS. 1 and 2, the control section 57 and the safety device 58 are housed in a control box (C), and the control box C is placed outside the front side wall 1 of the bathroom unit A. It is attached to the upper side.

As shown in FIG. 7, the operation panel 59 is attached to the inner surface of the left side wall 4 in the vicinity of the air amount adjusting handle 53b so that the bubble generating bath A can be operated.

In the bathroom unit A equipped with such a bubble generating bath B, the bath unit jetting sound from the jet nozzles 46, 46, 47, 47, bubble burst sound, operating noise of the circulation pump P and the motor M, etc. A loud noise is generated inside A, and the tiles are laid inside the side wall of the bathroom unit A, so the noise reverberates, causing discomfort to the bather and noise leaking outside the room. May be annoying.

Therefore, in the present invention, FIG. 2 to FIG. 5 and FIG.
, The partition wall a is kept below the ceiling wall 5 of the bathroom unit A at a constant interval, and a predetermined gap is provided between the peripheral edge of the partition wall a and the side walls 1, 2, 3, and 4. By holding and tensioning it, the interference-type silencing space S is provided between the partition wall a and the ceiling wall 5.
Is formed, and the noise is silenced in the same space S.

That is, the gushing sound of the bath water, the bursting sound of the bubbles,
Noise such as operating noise of circulation pumps and motors is generated by the bathroom unit.
It reflects on the floor pan 6 of A, side walls 1, 2, 3, 4 etc. and travels upward, passing through a predetermined gap between the peripheral edge of the partition wall a and side walls 1, 2, 3, 4. And enters the space formed by the ceiling wall 5 and the partition wall a.

Thus, the noises that have entered from the four circumferences of the partition wall a cross each other in the silencing space S and are silenced by mutual interference.

Particularly, since the interference type silencing space S is formed by the ceiling wall 5 and the partition wall a stretched below the ceiling wall 5, a large volume space S can be formed, and low-frequency noise that is hard to be attenuated. Can be effectively silenced.

Next, the partition wall a will be described with reference to FIGS.

FIG. 8 is a PVC steel plate composite panel, SMC, F.
A plate material such as RP or HIPS is used as a partition wall a for holding a constant distance g1 from the lower surface of the ceiling wall 5 and a peripheral edge portion a1 of the partition wall a.
And the side wall 1, 2, 3, 4 of the bathroom unit A
The sound deadening space S is formed by holding and stretching. 100 is a bulkhead fixture.

In FIG. 9, a large number of through holes a3 are bored in the partition wall a, and the space S is constructed as a sound deadening space that serves both as an interference type and a resonance type to enhance the sound deadening effect.

FIG. 10 shows the lower surface of the ceiling wall 5 and the upper surface of the partition wall a.
A sound absorbing material a4 made of a foamed plastic plate, a glass wool board, a perforated plate or the like is attached to enhance the sound deadening effect.

[0041]

According to the present invention, the following operational effects are brought about.

That is, the noise generated in the bubble generating bathtub installed in the lower part of the bathroom travels upward or directly due to the reflection on the floor surface and the wall surface, and passes through the gap between the peripheral edge of the partition wall and the side wall. , Enter into the space formed by the ceiling wall and partition wall.

In this way, the noises that have entered from the four circumferences of the partition wall intersect in the space and are silenced by mutual interference.

In particular, since the interference type silencing space is formed by the ceiling wall and the partition wall stretched below the ceiling wall, the space can be made large, and low-frequency noise that is difficult to attenuate can be effectively damped. You can

Further, a large number of through holes may be formed in the partition wall so that the space acts as a resonance type sound deadening space, or a sound absorbing material is attached to the lower surface of the ceiling wall and / or the upper surface of the partition wall to absorb sound. The sound deadening effect can be enhanced.
