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 a drain port mounting cylinder (chute) attached below the sink drain port, vibrations generated from the disposer body are transmitted to the drain port through the drain port side cylinder to generate noise. Occurs. For this reason, measures for suppressing this noise are required.

FIG. 4 shows one example of a conventional 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 character c denotes a drain port mounting cylinder body. The drain port mounting cylinder body c has a male screw portion e for screwing the fastening member d formed on the outside, and a flange-shaped upper portion corresponding to the low step portion b. An attachment portion f is formed at a lower portion of the attachment portion f. In this configuration, the flange-shaped mounting portion f and the low step portion b
By tightening the tightening member d with the rubber packing i interposed therebetween, the drain port mounting cylinder c is attached to the drain port, and then the rubber packing j is interposed between the upper portion of the disposer body g and the mounting portion h. Then, the disposer body g is attached to the drainage attachment cylinder c by tightening the fastening member k. For this reason, the disposer main body g can be detached from the drainage attachment cylinder c by loosening the fastening member k to perform maintenance.

A drain port mounting cylinder c,
The rubber packings i and j interposed between the low step portion b of the drain port and the disposer main body g are for water sealing, and are so-called tightening, that is, in a compressed state, so as to suppress vibration transmission. Does not contribute much. Therefore, noise due to vibration generated from the disposer main body g cannot be sufficiently reduced. In addition, although a proposal has been made to support the disposer main body with a suspension structure having a vibration-proof function, the vertical vibration-proof effect is not always sufficient. The present invention solves such a problem, and by further increasing the vertical anti-vibration effect, effectively reduces the transmission of vibration generated from the disposer main body to the sink through the drain-side cylinder. It is intended to suppress the generation of noise.

In order to solve the above-mentioned problems, according to the present invention, there is provided a drain port side cylinder which is attached to a sink drain port and protrudes downward, and a main body side cylinder to which a disposer body is attached. In addition to providing a flexible tubular body, a flange-shaped support body is protruded in the lateral direction of each of the drain side tubular body and the main body side tubular body, and fitting holes are provided at a plurality of corresponding positions of each brim-shaped support body. At the same time, the support rod is fitted by fitting an elastic bush into the fitting hole, stoppers are provided at both ends of the support rod, and at least the stopper and the elastic bush are provided at the brim-shaped support of the main body side cylinder. It is proposed to interpose an elastic cylindrical body on the body.

According to the present invention, it is proposed that in the above structure, an elastic bush similar to that mounted in the fitting hole be used as the elastic cylinder.

In the present invention, a flexible tubular body is provided between a drain-side tubular body attached to a sink drainage port by a fastening member and projected downward, and a main-body-side tubular body to which a disposer body is attached. A flange-shaped support is protruded in the lateral direction of each of the drain-side cylindrical body and the main-body-side cylindrical body, and fitting holes are provided at a plurality of corresponding positions of each brim-shaped support. The support rod is fitted to the support rod, stoppers are provided at both ends of the support rod, and a compression coil spring is interposed between the stopper and the flange-like support at least in the flange-like support of the main body side cylindrical body. Suggest to do.

Further, according to the present invention, in the above configuration,
It is proposed that the flexible cylinder is made of antibacterial rubber.

According to the present invention, the disposer main body is supported in a suspended structure by the plurality of elastic bushes or the elastic bush and the supporting rod body having the elastic cylinder or the compression coil spring interposed therebetween. The transmission of the vibration to the side can be suppressed by the plurality of elastic bushes or the elastic bush and the elastic cylinder or the compression coil spring. Therefore, the noise level generated from the sink by the disposer main body can be reduced.

In this case, the plurality of elastic bushes or the elastic bush and the elastic cylinder or the compression coil spring are arranged so that a compressive force is applied by the load of the disposer main body, and when the elastic bush and the spring are damaged. The disposer itself does not fall off. In addition, although the structure is long in order to further enhance the vibration isolation effect in the vertical direction, it does not buckle due to the compressive force because the support rod penetrates.

Further, since the disposer main body is supported by the suspension structure having an anti-vibration effect as described above, the flexible tubular body can be configured as a simple cover for falling garbage and the like. It is not necessary to consider special strength, anti-vibration performance, etc.
Antibacterial rubber suitable for use in such places can be used as a material for the cover.

Reference numeral 10 denotes a main body side cylindrical body to which the disposer main body 11 is attached. A flange-like support body 12 corresponding to the brim-like support body 9 of the outer cylindrical body 8 projects from an intermediate portion of the main body side cylindrical body 10. The disposer main body 11 is attached below the brim-shaped support 12.

The outer side of the outer cylindrical body 8 and the main body side cylindrical body 1
The flexible tubular body 13 is connected between the outside of the “0”. The connection method shown in the drawing will be described in detail. In this embodiment, an engagement groove 14 is formed on the outer periphery of each of the outer cylindrical body 8 and the main body side cylindrical body 10 and the upper and lower portions of the flexible cylindrical body 13 are formed. A ridge 15 that engages with the engagement groove 14 is formed on the inner periphery, and the upper and lower portions of the flexible cylinder 13 are fitted to the outer cylinder 8 and the outer side of the main body cylinder 10, respectively. Is engaged with the engaging groove 14, and then the outer periphery of the flexible cylindrical body 13 is tightened by the tightening band 16 to perform connection. In this embodiment, the flexible cylindrical body 13 is formed in a bellows shape in order to improve flexibility in shape.

Further, supporting portions 17a and 17b are formed at a plurality of positions corresponding to the brim-like supports 9 and 12, respectively, in FIG. 2, and at three positions separated by an angle of 120 degrees, respectively. , 17b are formed with fitting holes 19a, 19b whose peripheral edges are made thin so that the elastic bushes 18a, 18b made of rubber cylinders can be mounted.

The elastic bushes 18a, 18b are respectively provided in the fitting holes 19a, 19b of the support portions 17a, 17b.
After fitting and mounting, the bolt 20 is
8a is inserted from above, and penetrates this elastic bush 18a and lower elastic bush 18b. Next, another suitable number, in this case, two elastic bushes 21 are fitted and overlapped on the tip side of the bolt 20 penetrating the lower elastic bush 18b, and the nut 22 is tightened in this state to support the upper and lower brim-like supports. By fixing the body 9 and 12 while adjusting the distance therebetween, the main body side cylinder 10 can be supported by the drain port side cylinder 3 in a hanging structure with the bolt 20. The nut 23 is fixed with a locking agent to prevent loosening, and the nut 2
2 is configured as a double nut to prevent loosening.
In this embodiment, the bolt 20 corresponds to the above-mentioned support rod, and the nut 23 and the nut 22 on the head side of the bolt 20 correspond to the above-mentioned stopper.

In the above configuration, if the outer cylinder 8 is rotated with the rubber packing 24 interposed between the flange-shaped mounting portion 5 and the lower step portion 2 of the inner cylinder 6, the female screw 7 and the inner thread are rotated. Since the upper surface of the brim-shaped support 9 and the lower surface of the brim-shaped mounting portion 5 sandwich the rubber packing 24 and the low step portion 2 by being screwed together by the screwing of the male screw portion 4 of the cylindrical body 6, Can be attached to the drain port of the sink plate 1. Next, by attaching the disposer main body 11 to the lower side of the main body side cylindrical body 10, the disposer main body 11 can be supported below the drain port of the sink with a suspension structure mainly by bolts 20. In this case, the disposer main body 11 is attached to the main body side cylinder 10 by applying the above-described conventional attachment mechanism or by using the engaging ridge 25 formed on the outer periphery of the lower part of the main body side cylinder 10. Alternatively, an appropriate method such as a method of forming a male screw portion on the outer periphery of the lower part of the main body side cylindrical body 10 and mounting using the male screw portion, or a method of mounting them in combination may be applied.

When the disposer body 11 is used, the garbage thrown into the drain-side cylinder 3 opened in the sink is passed through the inner cylinder 6, the outer cylinder 8, and the body-side cylinder 10 to form the disposer body. 11, and is provided for processing by a rotary cutter or the like. At this time, the vibration generated in the disposer main body 11 is transmitted to the main body side cylindrical body 10, and the main body side cylindrical body 10 is suspended by the bolt 20 via the elastic bushes 18 b, 21 at a plurality of places of the brim-shaped support 12. Since the bolt 20 is supported by the brim-shaped support 9 via the elastic bush 18a,
Transmission of vibration to the brim-like support 9 is suppressed. That is, in this embodiment, the bolt 20 and the brim-like supports 9 and 12 are used.
In addition to the elastic bushes 18a and 18b being interposed between the respective support portions 17a and 17b, the elastic bush 18b is provided between the bolt 20 and the brim-like support 12 of the main body side cylindrical body 10. In addition, since an appropriate number of other elastic bushes 21 are interposed in a stacked state, the vibration transmitted from the disposer main body 11 to the main body side cylinder 10 is absorbed by the elasticity of these elastic bushes, and the horizontal and vertical directions are absorbed. The transmission of vibrations can be suppressed, and vibration can be prevented. In particular, between the bolt 20 and the brim-shaped support body 12 of the main body side cylindrical body 10, an appropriate number of other elastic bushes 21 are stacked in addition to the elastic bush 18b, and the elastic portion is configured to be long. The effect of suppressing vibration transmission is great. Further, the elastic bushes stacked in this way make the elastic portion long, and a compressive force acts thereon. However, since the bolts 20 penetrate these, they do not buckle due to the load. In this embodiment, the two elastic bushes 21 have the flat washers 26 mounted in the mounting grooves on the outer periphery thereof, so that unnecessary buckling deformation of these portions can be suppressed. As described above, since the two elastic bushes 21 do not need to be mounted on the supporting portions 17a, 17b, etc. unlike the elastic bushes 18a, 18b, it is not essential to provide a mounting groove. A cylindrical body can also be used.

Next, FIG. 3 shows a second embodiment of the present invention, and is a sectional view of a portion similar to FIG. This second
In this embodiment, instead of the appropriate number of elastic bushes 21 in the first embodiment, a compression coil spring 27 is interposed between the collar-shaped support 12 and the nut 22 of the main body side cylindrical body 10. . Reference numeral 28 denotes a spring retainer.
When there is no load, for example, when the disposer main body 11 is not yet mounted on the main body side cylinder 10 or during distribution as an anti-vibration mounting mechanism, the elasticity of the compression coil spring 27 causes the main body side cylinder 10 and the drain port side cylinder It is a stopper for preventing the distance between the bodies 3 from moving in a direction in which the distance is reduced more than necessary.
The other components are the same as those in the first embodiment, and a description thereof will not be repeated.

In such a configuration, the elastic portion between the bolt 20 and the brim-shaped support 12 of the main body side cylinder 10 is elongated by the compression coil spring 27 in addition to the elastic bush 18b, so that the vibration is reduced. Great transmission suppression effect. Further, the compression coil spring 27 is configured to be long as described above, and a compression force acts on the coil spring 27.
There is no danger that the disposer body 11 will fall off even if it is damaged.

In each of the first and second embodiments, the suspension structure in which the elastic portion is compressed by the load maintains the support of the disposer body 11 even if the elastic portion is damaged. Is safe.

Further, in the present invention, since the disposer body 11 is supported by the suspension structure having a vibration-proof effect as described above, the flexible cylindrical body 13 can be configured as a simple cover when food garbage or the like falls. . Therefore, in this case, it is not necessary to consider special strength, vibration isolation performance, and the like, and these performances are reduced, but an antibacterial material can be used as the material of the flexible tubular body 13. As the antibacterial agent, for example, an antibacterial rubber or a soft plastic obtained by mixing an ordinary rubber with an inorganic or organic iodine-based antibacterial agent in an amount of 0.1% or more can be used.

In the embodiment shown in FIG.
3 is located at a distance outside the chute-like lower part of the outer cylinder 8, and the lower end of the flexible cylinder 13 exposed to the inside is higher than the chute-like lower end of the outer cylinder 8. , It is possible to prevent garbage passing through the outer cylindrical body 13 from adhering to the flexible cylindrical body 13.
