Abstract

PURPOSE:To reduce noises produced by water dropping from a faucet to a sink tank and washing operations. CONSTITUTION:A stainless steel sink tank 11 is installed below an opening 10a of a work-top 10. A water faucet is fitted to the work-top 10 located behind the sink tank 11. While a tap is provided pivotably, the sink tank 11 is provided with a drain port. A water condeusation preventing member 17 provided with an opening hole 18 is fitted to the outer wall surface of the sink tank 11 and a vibration damping material 12 is fitted by means of an adhesive gent to the opening hole 18 of the moisture condensation preventing member. The vibration damping material 12 is made of styrene vinyl acetate or butyl rubber. Thus, since the vibration damping material 12 is fitted to the outer wall surface of the sink tank, a vibration damping effect is displayed so that noise produced by shower and washing work can be reduced while the vibration damping materials 12 can be effectively surely fitted to a set position by fitting the vibration damping material 12 to the opening hole of the moisture condensation preventing material.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sink for a system kitchen or the like.

[0002]

2. Description of the Related Art Conventional sinks are simply covered with a dew condensation preventing material such as urethane foam or polyethylene foam.
To prevent vibration and noise generated in the sink tank, no measures have been taken except the method of press-molding the sink tank with viscoelastic resin sandwiched between steel plates. There wasn't.

[0003]

With the anti-condensation material coated on the sink tank as described above, the viscoelastic effect, the mass effect, etc. for suppressing the vibration cannot be sufficiently expected,
Therefore, it was impossible to reduce the vibration of the sink tank caused by the water falling from the faucet into the sink tank and the noise induced thereby.

On the other hand, in the proposal using the above-mentioned sandwich type vibration-damping steel plate, this steel plate cannot be deep-drawing pressed like a sink tank, or cannot be welded because resin is interposed, resulting in cost reduction. There are still many problems such as high price.

The present invention is intended to solve such a problem, and is intended to reduce vibrations caused by water falling from a faucet into a sink tank, and further to reduce accompanying noise. This is intended to improve productivity.

[0006]

According to the sink of the present invention, the outer wall of the sink tank is covered with a dew condensation preventing material, and the dew condensation preventing material has at least an opening for mounting a damping material on the wall surface facing the outer wall surface of the sink tank. A hole is provided, and the damping material is attached to the opening hole.

[0007]

In the sink tank of the present invention, a damping material is attached to a part of the outer wall surface of the sink tank. This damping material prevents the vibration of the surface generated when water or tableware falls. Suppress,
Furthermore, it is possible to suppress impact noise and noise generated from this aspect.

Further, the anti-condensation material attached to the outer wall surface of the sink tank is provided with an opening hole for attaching the damping material, and the damping material is attached to the opening hole. It is securely attached and the attachability is improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In the figure, reference numeral 10 is a sink worktop, and a sink tank 11 made of stainless steel is attached below the opening 10a of the worktop 10. A water tap 14 is attached to a worktop 10 located behind the sink tank 11, and a faucet 13 is rotatably provided. Reference numeral 15 is a drain port of the sink tank 11. A dew condensation preventing material 17 having an opening 18 is attached to the outer wall surface of the sink 11 and a damping material 12 is attached to the opening 18 of the dew preventing material with an adhesive material. The vibration damping material 12 is made of styrene-vinyl acetate or buty rubber.

In the above structure, the water flow from the faucet 14 falls on the bottom surface of the sink tank 11 to the position indicated by the alternate long and short dash line.
The generation of noise is high, especially when used in a shower. In the case of the sink tank 11 as in the present embodiment, generally, the washing work of dishes and the like is carried out by deviating to either side of the sink tank 11. At that time, noise when water falls, sounds such as dishes hitting the sink 11 are generated. The noise of water is magnified not only by the noise generated by the shower falling, but also by the noise generated by the large drops of water dripping from the dishes during the washing operation. Therefore, if the mounting position 16 of the damping material 12 is set to the position where the water flow falls from the faucet 13 and the most used place for washing work as in this embodiment, vibration and noise can be effectively reduced. did it. The measurement example is shown in the following table. Table 1 shows the faucet 1 shown in FIG.
3 shows the measurement results at the position 3 (shower state).

[0012]

[Table 1]

As shown in Table 1, the value of 73 dB when the damping material 12 is not attached is reduced to 70 dB when the damping material 12 is attached directly below the shower, and the noise reduction effect is great. Is shown. On the other hand, when the shower was installed with the drop position removed, the position dropped by 71.5 dB to 1.5 dB as at position 12-B. 1
When it was attached to both 2-A and B, it was 69.5 dB, and the reduction effect was slightly increased compared to the case of 12-A. Therefore, the mounting position 16 of the damping material 12
The most effective noise suppressing effect can be obtained by setting the point where vibration occurs to suppress the initial vibration having the highest energy.

The portion shown by the broken line in FIG. 4 is the place where the damping material 12 is attached from the back of the sink tank 11. The position where the water flow from the faucet falls, and the place where it is used for washing work etc. By including "," noise was reduced during actual use.

In this embodiment, the vibration damping material 12 is used as described above.
The noise generated from the sink 11 by using
Since it can be reduced by dB or more and resonance is suppressed, an excellent effect such as adding a profound feeling to the tone color can be obtained. Moreover, in the present embodiment, the dew condensation preventing material 17 is provided with the opening hole 18, and the damping material 1 is provided in the opening hole 18.
Since 2 is attached, the attachment position of the vibration damping material 12 becomes reliable and the attachability is improved.

On the other hand, sound absorbing materials such as urethane foam and polyethylene foam do not themselves have a vibration-damping effect, but because they are foamed resins, they have a sound absorbing effect.
Therefore, by attaching the damping material 12 to the sink tank 11 and further covering it with a sound absorbing material, the sound absorbing effect of these foamed resins is utilized, suppressing the resonance of sound into the cabinet in which the sink tank 11 is installed, and reducing the noise. Can be further enhanced.

[0017]

As is apparent from the above description of the embodiments, according to the present invention, since the damping material is attached to the outer wall surface of the sink tank, the damping effect is exerted and it is effective in showering and washing work. In addition to being able to reduce the noise generated,
Further, the vibration damping material is also attached to the dew condensation prevention material by providing the vibration damping material in the opening hole so that the vibration damping material can be surely attached at the set position.
