Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a kitchen for disposer installation.

[0002]

2. Description of the Related Art Disposers, which are equipment for processing garbage in kitchens, have been widely used, especially in apartment houses, as being very useful for reducing garbage and sanitizing kitchens.

[0003] However, since the disposer is installed in the storage space below the kitchen sink and crushes and disposes of garbage introduced through the drain of the sink, noise generated when crushing garbage is generated. There is a problem to be solved how to reduce this noise, which is noisy when transmitted to the room or next door.

In order to solve this problem, conventionally, a lid attached to a raw garbage charging section into the disposer has been improved, the disposer has a vibration-proofing support, and a mechanism for supplying water to the disposer has been improved. Improvements have been made to the structure of the disposer body.

[0005] However, although each of these methods has a certain effect, it is not always possible to obtain a satisfactory noise prevention effect. In particular, the low-frequency sound that occurs when the disposer crushes relatively hard objects such as fish and chicken bones can be suppressed easily by simply using a soundproof lid for the lid, improving the water supply mechanism, or improving the disposer body I can't. Also, if you try to control the propagation of low-frequency sound with the anti-vibration support of the disposer,
The structure becomes very complicated.

The present invention has been made in view of the above problems, and has an object to effectively suppress the transmission of disposer sound to a room or a neighboring door, including the transmission of low-frequency sound. As an issue.

[0007]

In order to solve the above-mentioned problems, the present inventors have made extensive studies and as a result, the vibration of the sound from the disposer is transmitted to the sink, and the vibration of the sink causes the sound to be heard indoors or next to the room. We found out that this is one of the major causes of noise that propagates to doors. Based on this fact, the present inventors have found that by suppressing the vibration of the sink due to the vibration of the sound from the disposer, it is possible to effectively suppress the propagation of sound to the room or the next door. Completed.

[0008] That is, the above problem is solved by a kitchen for disposer installation, characterized in that the sink is configured as a vibration damping sink that suppresses vibration due to vibration transmitted from the disposer.

In this disposer installation kitchen,
Even if the vibration of the sound generated from the disposer is transmitted to the sink, the sink acts to suppress the vibration due to the vibration. This makes it possible to effectively suppress the propagation of the disposer sound to the room or the next door, including the propagation of low-frequency sound.

In particular, since the sink itself is used as a vibration damping sink, not only the vibration transmitted from the disposer to the sink through a solid (for example, a connecting portion between the disposer and the sink) but also the vibration transmitted from the disposer to the sink through air. Thus, the vibration of the sink can be suppressed, and the propagation of sound to the room or the adjacent door through the sink can be effectively suppressed.

When the sink is provided with a damping layer on the back surface of the sink body, the vibration of the sink can be effectively suppressed without impairing the original usability of the sink. The damping layer can be formed, for example, by bonding a sheet-shaped damping material to the back surface of the sink main body, or by applying an application type damping material to the back surface of the sink main body.

When the sink is made of a stainless steel plate having a thickness in the range of 0.5 to 2.5 mm, when the sink is used as a vibration damping sink, the sink itself should suppress its own vibration. And the sink is structurally solid. If the thickness is smaller than 0.5 mm, it is difficult to obtain a sufficient vibration damping effect. If the thickness is larger than 2.5 mm, the processing of the sink body becomes difficult or the weight becomes too large, which causes trouble in handling. May occur. Preferably, the thickness dimension is at least 0.8 mm, more preferably at least 1.0 mm. The upper limit is preferably 2.0 mm or less, more preferably 1.5 mm or less.

In the case where the sink is made of a damping steel plate by using a damping steel plate, the sink body does not have to be large in thickness, and the weight of the sink body is kept small. At the same time, it is possible to effectively suppress its own vibration.

When the sink is provided with a mass for vibration suppression in the sink body to be a vibration suppression sink, the vibration of a specific frequency to be controlled is aimed at and the vibration of that frequency is intensively controlled. Therefore, it is possible to effectively suppress the propagation of noise due to low-frequency sound, particularly when crushing hard objects such as bones. This mass method is more effective when used in combination with the above-mentioned damping layer type, thick wall type, damping steel plate type, and the like.

[0015]

Next, embodiments of the present invention will be described with reference to the drawings.

In the first embodiment shown in FIG.
1 is a kitchen for disposer installation, and 2 is a disposer. The kitchen 1 is installed so that the back side thereof is along the boundary wall 4 with the adjacent door 3, and the disposer 2
Is installed using a space in a storage space section 6 provided below the sink 5 of the kitchen 1,
Garbage can be put into the disposer 2 through this drain port.

In the kitchen 1 described above, the sink 5
Damping layer 8 on the back of sink body 7 made of stainless steel plate
Is provided, whereby the vibration control sink is configured to suppress itself from being vibrated by the vibration transmitted from the disposer 2. In the present embodiment, the damping layer 8 is made of a sheet-shaped damping material, and is provided by attaching and joining the sheet-shaped damping material 8 to the back surface of the sink body 7. As the sheet-like vibration damping material 8, various sheets containing components having a large specific gravity such as iron and lead may be used, and there is no particular limitation. However, the sink body 7
Since the shape of the back side of is not necessarily flat, it is preferable to use a flexible and resilient sheet that can conform to the back shape of the sink body 7. Note that a damping sheet formed in advance in a shape corresponding to the shape on the back side of the sink body 7 may be used, and this may be joined to the back side of the sink body 7.

In the kitchen 1, the disposer 2
The vibration of the sound emitted from the disposer 2 while the garbage is being crushed is transmitted to the sink 5 through the portion connecting the disposer 2 and the sink 5 and the air around the disposer 2. Is configured as a vibration damping sink provided with the vibration damping layer 8, so that vibration due to vibration of sound from the disposer 2 can be suppressed.
Thereby, the vibration of the sound from the disposer 2 can be suppressed from being transmitted to the room or the next door 3 through the sink 5, and the propagation of the disposer sound to the room or the next door 7 can be reduced to the propagation of the low-frequency sound. Can be effectively suppressed. Moreover, since the sheet-shaped vibration damping material 8 is attached to the back of the sink body 7, the original usability of the sink is not impaired.

In the kitchen 1 of the second embodiment shown in FIG. 1B, the sink 5 is configured as a damping sink by applying a coating type damping material 9 on the back side of the sink body 7. .
The coating type vibration damping material 9 is widely provided, and various coating type vibration damping materials may be used. By forming the damping layer with the coating type damping material 9, it is possible to easily form the damping layer 9 on the sink body 7.

In the kitchen 1 according to the third embodiment shown in FIG. 2A, the sink 5 is configured as a vibration damping sink by providing weights 10 for vibration damping on the back side of the sink body 7. . In the kitchen 1, by setting the weight, the number, and the arrangement of the weights 10, the target of the vibration of a specific frequency to be damped is set, and the vibration of the frequency is transmitted to the room or the adjacent door 3 through the sink 5. Can be suppressed.
Therefore, it is possible to effectively suppress the propagation of noise due to low-frequency sound when crushing bones.

In the kitchen 1 according to the fourth embodiment shown in FIG. 2B, the vibration control sink 5 of the kitchen 1 according to the first embodiment shown in FIG. It is.
In the vibration damping sink 5, the propagation of the disposer sound to the room or the adjacent door 3 through the sink 5 is performed by the vibration damping action of the sheet-shaped vibration damping material 8 and the vibration suppressing action of the specific frequency by the vibration damping weights 10. , Including the propagation of low frequency sounds.

In the kitchen 1 of the fifth embodiment shown in FIG. 3A, the thickness of the stainless steel plate forming the sink body 7 is set to, for example, 1.2 mm thick, so that the 7 itself functions as a vibration damping material. Vibration propagation through the sink 5 can be suppressed with a simple structure.

In the kitchen 1 of the sixth embodiment shown in FIG. 3B, the sink body 7 is made of a damping steel plate 11 joined by sandwiching a viscoelastic resin layer between steel plates. Vibration can be effectively suppressed without increasing the weight of the sink body 7 significantly.

Incidentally, the noise reduction effect of the disposer was compared between the case where the kitchen sink was a vibration damping sink and the case where the kitchen sink was a normal sink, and the result shown in FIG. 4 was obtained. From this result, it can be seen that the noise from the disposer can be effectively reduced by using the sink of the kitchen as the vibration damping sink.

Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention. For example, in the above embodiment, some examples have been described in which the sink is used as a vibration damping sink. However, the present invention is not limited to these, and the point is that the sink suppresses vibration due to vibration transmitted from the disposer. It should just be done. In addition, it goes without saying that the kitchen for disposer installation of the present invention can be widely used not only for apartment houses but also for kitchens of detached houses and various kitchens.
