Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-vibration device for connecting a disposer, which cuts kitchen garbage generated in a kitchen into small pieces and discharges it together with water, into a drain of a sink of a sink, and a rotation prevention device for the apparatus. It relates to members.

[0002]

2. Description of the Related Art Disposer (108), which is a kitchen garbage disposal device, is widely used in the United States and is showing signs of widespread use in Japan. However, in order to popularize the disposer (108) in Japan, wastewater treatment and noise during operation become problems. Especially the noise during operation is disposer
Since the (108) is connected to the sink (109) of the sink via the drain mounting cylinder (101) attached to the drain (110) of the sink (109) of the sink, (Ten
The vibration of 8) is transmitted to the sink (109) formed of a thin stainless plate through the drain port mounting cylinder (101) and generates noise.

FIG. 6 is a cross-sectional view of a conventional vibration isolator (B), in which a collar-like mounting portion (112) of a drainage side tubular body (101) is tightened through a rubber packing (111) with a fastening member (113). By the drain of the sink (109)
It is stuck to (110). On the other hand, the disposer-side cylinder (102) is screwed to the upper end of the disposer (108), and the drainage channel has rubber at the lower end of the drainage mounting cylinder (101) and the upper end of the disposer-side cylinder (102). The disposers (108) are connected by a tubular body (114) and are supported in a state of being suspended from the disposer-side tubular body (102).

[0004] Disposers (108) are thrown into raw garbage without distinguishing not only vegetable scraps but also pointed fish bones and hard bird bones, and finely crushed by the disposer (108). Will be discharged together with water. The noise is generated when the amount of input to the disposer (108) is large and the load becomes excessive, or when the disposer (108) crushes hard fish bones or hard bird bones.

In such a conventional vibration isolator (B), the fish thrown into the disposer (108) through the universal lid (115) provided on the drain side tube (101). Prevent the rubber barrel (114) from breaking because hard garbage such as bones and bird bones directly contacts the rubber barrel (114), and directly load the disposer (108) and load or start the garbage. Since it was necessary to withstand the twisting force of the desposer (108) at that time, a somewhat hard rubber material had to be used. Then, the vibration generated during the operation of the disposer (108) is transmitted to the drain side cylinder (101) through the rubber cylinder (114), and this is transmitted to the sink (109) to generate noise. , The soundproofing effect was not as expected.

Therefore, a vibration isolator (C) as shown in FIG. 7 has been proposed. That is, the drain port side tubular body (201) and the disposer side tubular body (202) are connected by a flexible rubber tubular body (214) having a bellows part in the middle, and the drain port side tubular body (201). The member to be suspended (205) is elastically suspended by the elastic suspension member (206) on the suspension member (204) extended from the drainage port side cylinder body (201).
Was extended so as to be positioned inside the flexible rubber cylinder (214). As a result, the flexible rubber tubular body (214) is protected by the extended portion (201a) of the extended drain side tubular body (201) and the load is carried by the elastic suspension member (206). Therefore, the flexible rubber tubular body (214) can be formed of a softer rubber than that of the first conventional example, and the vibration is absorbed through the hard rubber tubular body (114) which is a problem of the first conventional example. The phenomenon of being transmitted to (109) has been resolved to some extent.

However, the flexible rubber cylinder (2
When the disposer (208) is operated, the upper and lower ends of (03) are fixed to the disposer-side cylinder (202) and the drain-side cylinder (201) with bands (209) and (210), respectively. Vibration of the flexible rubber cylinder (203) itself is transmitted from the disposer side cylinder (202) to the drain side cylinder (201), the initial movement of the flexible rubber cylinder (203) Twist (Disposer (2
(08) Twist that occurs during initial movement) and that when a load is applied, the vibration-proof performance was insufficient, and the shaft (206a) of the elastic suspension member (206) supported the suspended member ( Since 205) is elastically suspended by the suspension member (204), the shaft (206a) causes the suspension member (204) to rotate when the above-mentioned initial torsion or twist occurs when a load is applied. ) Is strongly pressed by the rubber seat (204a) attached to the (), and vibrations are transmitted from this part, and there are still problems, and the vibration damping effect can be solved sufficiently as expected. could not.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems of the conventional example as described above.

In this way, all the load on the disposer (8) side is carried by the elastic suspension member (6).

Between the suspending member (4) and the suspended member (5), there are at least two symmetrical positions between the elastic suspending members (6) or as shown in FIG. Anti-rotation members (7) are installed at three locations at equal intervals. The rotation prevention member (7) is for stopping the twist at the start of the disposer (8),
FIG. 1 shows an example thereof. That is, the hanging ring body plate (46)
An anti-rotation rod (72) is fixed to the lower surface of the bolt (75) with a bolt (75), and is a ring-shaped swivel jointly fixed to the outer flange (65) of the suspended member (5). Correspondingly, a detent block (74) is provided upright on the detent mounting plate (77), and the detent block (74) and detent rod (72) have an elastic bellows tubular body having a folded portion. Connected at (73). The elastic bellows cylinder (73) is fixed by fixing bands (73a) and (73b). The detent block (74) is fixed to the detent mounting plate (77) with a bolt (80).

Reference numeral (15) is a universal lid, which is attached to the inside of the upper end of the lower cylindrical body (33), and has a radial notch groove formed in the center thereof, and a notch piece around the insertion port (16). (17) surrounds it, making it difficult for the thrown food waste to go back. In addition, an obstruction lid (1
8) is detachably installed. The closing lid (18) is a dish-shaped lid body (18a), a knob (18b) attached to the center of the lid body (18a), and a ring-shaped lock attached to the peripheral portion of the lid body (18a). The ring-shaped locking portion (18a) is placed on the mounting uneven portion (31) of the upper drainage tubular body (21).

Next, the operation of the first embodiment (A1) will be described. When kitchen work is performed, a large amount of garbage such as vegetable scraps, fish bones and bird bones is generated. Then, the obstruction lid (18) is opened and the food waste is thrown into the disposer (8) through the free lid (15). Then, depending on the weight of the garbage, the suspension spring (70)
At the same time, the elastic bellows cylinder (73) is stretched by the same amount at the folded portion. After that, when the closure lid (18) is closed and the switch is turned on, the motor (not shown) of the disposer (8) is activated and the hammer (not shown) is rotated, and the raw material put into the disposer (8) is turned on. The dust is pressed against a fixed blade (not shown) and crushed, so that it flows out into the sewage together with the water.

At the time of starting the motor, a large twisting force is generated in the disposer (8), and the lower cylinder body (33) and the portion below the outer cylinder body (54) are rotated while waviness is generated in the vertical direction. try to. Depending on the amount of this twist, first the suspension spring
(70) flexes to carry the total twist load. At that time, a large vibration is transmitted from the disposer (8) to the suspension spring (70), but since the surging prevention material (79) is disposed inside the suspension spring (70), the suspension spring (70 70) The occurrence of surging is suppressed. Furthermore, since the suspension side arm member (37) is attached to the suspension ring main body plate (46) via the rubber elastic body (48), the suspension side arm member (37) is suspended by the twisting. The suspension side arm member (37) that can be tilted in the twisting direction with respect to the holding ring body plate (46) and is made of a rubber elastic body (48).
It is possible to block even the slightest vibration that has been transmitted. As a result, the vibration transmission from the suspension side arm member (37) can be almost shut off.

On the side of the detent member (7), a detent block for the detent bar (72) generated by the twist.
The displacement of (74) is three-dimensional. It is possible to absorb the displacement in the vertical direction, the front-rear direction, and the left-right direction by the extension or deformation of the folded portion. Then, the vibration transmitted to the rotation stopper mounting plate (77) is blocked by the folded-back portion of the elastic bellows tubular body (73). For that purpose, it is preferable to use a flexible elastic bellows body (73) to some extent. The horizontal displacement due to the twist is the outer cylinder
The gap (K) between the lower cylinder body (33) and the lower cylinder body (33) is set to be less than or equal to the outer cylinder body (54) so that it does not contact the lower cylinder body (33). There is. Also, the deodorant elastic cylindrical body (58) is attached so that a bad odor does not leak from the gap between the outer cylindrical body (54) and the lower cylindrical body (33). Since (54) is disposed so as to overlap from the outside of the lower tubular body (33), this portion only needs to satisfy the deodorizing function, and an extremely thin rubber film is used. Therefore,
There is almost no vibration transmission from this part.

As described above, the large vibration and twist generated when the disposer (8) is activated, or the disposer (8)
Large vibrations and twists that occur when a bone-like object is placed in (8) prevent rotation (7) and elastic suspension members.
It is blocked by (6) and transmitted to the drain side cylinder (1) side is suppressed as much as possible, and noise at startup is suppressed to be small.

When the rotation of the motor of the disposer (8) is in a steady state, the torsional force disappears and the suspension spring (70) and the rotation preventing member (7) return to the original position, and thereafter, the above-mentioned exclusively. The suspension spring (70) provides vibration isolation. During this time,
While the disposer (8) is in operation, high-frequency vibration is always generated, but the suspension spring (70) effectively prevents vibration.

FIG. 2 shows a second embodiment (A2) of the present invention, which is different only in the rubber elastic body (48). In this case, the rubber elastic body (48a) has a nut (48b) embedded and baked and fixed on its upper surface, and a screw (48c) similarly embedded and baked and fixed on its lower surface. Then, the suspension ring main body plate (46) and the suspension side term member (37) are attached. Since the operation of this one is the same as that in the case of FIG. 1, its explanation is omitted.

FIG. 3 shows a third embodiment (A3) of the present invention.
Unlike the two embodiments (A1) and (A2), the rubber elastic bodies (48) and (48a) do not exist, and the hanging arm member (37) is directly attached to the hanging ring body plate (46) by the bolt (47). In this case, the rubber elastic body (48) (48a) does not exist in this case, so the vibration transmitted to the suspension arm member (37), though slight, remains unchanged. Since it is transmitted to (46), its vibration isolation performance is lower than that of the first and second embodiments (A1) and (A2).

Next, the first embodiment (A1) and the conventional example shown in FIG.
Compare the anti-vibration property with (C). FIG. 8 is a graph of vibration transmission of the first embodiment (A1), and FIG. 9 is that of the conventional example (C). The vertical axis represents speed (mm / sec), and the horizontal axis represents time (sec). The speed of vibration transmitted to the sink (9) when 150 g of ice was thrown was measured, and the speed of vibration when the ice was crushed when the disposer (8) was started was measured in the first embodiment (A).
In the case of 1), the average value is a maximum of 5 mm / second, and the speed of vibration when the cleaning water is injected during the operation of the disposer (8) is an average value of about 2.5 mm / second. On the other hand, the vibration speed at startup of the conventional example (C) is 6.5 mm at maximum on average.
/ Sec, and the speed of vibration when water for cleaning was injected during operation was about 3.5 mm / sec on average, and in any case, the first example (A1) was superior. It can be seen that the anti-vibration performance is exhibited.

[0034]

According to the present invention, the disposer-side cylindrical body is mainly carried by the elastic suspension member, but a slight amount transmitted to the suspension-side arm member through the elastic suspension member. The vibration is blocked by the vibration-blocking elastic body on the way, and is not transmitted to the sink side. In addition to this, since the anti-rotation member also has a soft elastic bellows cylinder having a folded portion in the middle, vibration transmission from the rotation-stop block is also blocked here. As a result, it is possible to prevent the vibration due to the pulverization of the input material at the time of starting or during operation from being transmitted to the sink side, and it is possible to realize a quiet kitchen environment. Further, due to the presence of the elastic bellows cylinder and the elastic body described above, the twist generated at the time of starting or crushing the input material during operation can be carried in these portions as well, and the ability to cope with the twist is improved. .
