2. Description of the Related Art Disposers, which are kitchen garbage disposers, are widely used in the United States, but when applied to Japan, wastewater treatment and noise are problems. That is, since the disposer body is attached via the drain-side cylinder (chute) attached to the lower side of the sink drain, vibration generated from the disposer body is transmitted to the drain through the drain-side cylinder and noise is generated. Occurs. For this reason, measures for suppressing this noise are required.

FIG. 9 shows a conventional example of a disposer mounting mechanism. Reference numeral a denotes a sink plate, and a drain port is formed in a low step portion b which is one step lower than the sink plate a. Reference numeral c denotes a drain port side cylinder, that is, a chute. The drain port side cylinder c has an externally threaded portion e for screwing the fastening member d formed on the outside, and the upper portion corresponds to the low step portion b. Flange-shaped mounting part f, mounting part h on lower part of disposer body g
Is formed. In this configuration, with the rubber packing i interposed between the brim-shaped mounting portion f and the low step portion b, the fastening member d
, The drain-side cylinder c is attached to the drainage port, and then a rubber packing j is interposed between the upper part of the disposer main body g and the mounting portion h to fasten the fastening member k to thereby discharge the drain-side cylinder. The disposer body g is attached to c. For this reason, the disposer main body g can be detached from the drain port side cylindrical body c by loosening the fastening member k to perform maintenance.

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows an embodiment relating to the basic configuration of the present invention. Reference numeral 1 denotes a sink plate of a sink. The sink plate 1 has a lower step portion 2 which is one step lower, and a drain port is formed in the lower step portion 2. Reference numeral 3 denotes a drain port side tubular body, a so-called chute. The drain port side tubular body 3 has a male screw portion 5 for screwing the fastening member 4 on the outside and a collar corresponding to the low step portion 2 at the upper portion. A mounting portion 6 is formed. Reference numeral 7 denotes a main body side cylinder to which the disposer main body 8 is attached. When attaching the disposer main body 8 to the main body side cylinder 7, the above-described conventional mounting mechanism is applied, or a male screw portion 9 is formed outside the main body side cylinder 7, and the disposer main body 8 is attached to the male screw portion 9. An appropriate method, such as a method of screwing and attaching a female screw portion formed on the upper part of the device, can be applied. In the above configuration, the vibration-proof cylinder 10 is connected between the lower part of the drain-side cylinder 3 and the upper part of the main-body cylinder 7. The connection method will be specifically described. In this embodiment, an engagement groove 11 is provided on the outer periphery of the lower part of the drain port side cylinder 3 and the outer periphery of the upper part of the main body side cylinder 7, and the upper part of the vibration isolating cylinder 10 is provided. And the engagement groove 11
Is formed, and the upper and lower portions of the anti-vibration cylinder 10 are fitted to the lower portion of the drain port side cylinder 3 and the outer side of the upper portion of the main body side cylinder 7, respectively. After engaging with the mating groove 11, the connection is made by tightening the outer periphery of the vibration-proof cylinder 10 with the tightening band 13. In addition, the connection method itself is appropriate. The anti-vibration material constituting the anti-vibration cylinder 10 is a requirement as an anti-vibration material, that is, an elastic body having elasticity over a wide range, and does not cause permanent distortion due to applied load and vibration, and supports the disposer body 8. Any material that satisfies that the material has sufficient strength and durability, is inexpensive, and the like, for example, a material such as rubber can be used.

In the above configuration, the drain port side cylinder 3 can be tightened by tightening the tightening member 4 with the rubber packing 14 interposed between the flange-shaped mounting portion 6 and the low step portion 2 as in the conventional case. The flange 25 and the attachment 6 of the fastening member 4 are

For this reason, it can be attached to the drain port, and the main body side cylinder 7 can be suspended and supported via the vibration-proof cylinder 10. Next, the disposer main body 8 can be attached to and supported by the main body side cylindrical body 7 using the male screw portion 9 or the like. Then, the disposer main body 8 can be removed as necessary at the time of maintenance or the like, as in the related art.

When the disposer body 8 is used,
The garbage thrown into the drain-side cylinder 3 opened in the sink is thrown into the disposer body 8 through the flexible cover 15, the vibration-proof cylinder 10, and the body-side cylinder 7, and processed by a rotary cutter or the like. To be served. At this time, the vibration generated in the disposer main body 8 is transmitted to the anti-vibration cylinder 10 via the main body-side cylinder 7, but the vibration-proof cylinder 10 suppresses the propagation to the drain port-side cylinder 3. Therefore, the energy of the vibration transmitted from the disposer body 8 to the sink is reduced, and the noise level is reduced.

From the viewpoint of suppressing vibration transmission, a soft vibration-proof material itself may be used for the vibration-proof cylinder 10,
It is preferable to reduce the spring constant by increasing the length or reducing the thickness, but from the viewpoint of supporting the disposer body 8, the opposite is more preferable from the viewpoint of strength and durability, and the contrary Performance is required.

Therefore, the first embodiment of the present invention shown in FIGS. 2 and 3 is configured to satisfy such a trade-off performance. This embodiment is substantially the same as the embodiment of the basic configuration, and the same components are denoted by the same reference numerals and overlapping description will be omitted.
