Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a vibration-proof mounting device for connecting a disposer for finely cutting garbage generated in a kitchen and discharging it together with water into sewage to a drain outlet of a sink of a sink.
[0002]
[Prior art]
Disposer (108), which is a kitchen garbage disposal device, is actively used in the United States, and is showing signs of widespread use in Japan. However, in order to spread the disposer (108) in Japan, wastewater treatment and noise during operation are problems. In particular, during operation, the disposer (108) is connected to the sink sink (109) through the drain mounting cylinder (101) attached to the lower side of the drain outlet (110) of the sink sink (109). Therefore, the vibration of the disposer (108) during operation is transmitted to the sink (109) formed of a thin stainless steel plate through the drain port attachment cylinder (101), and noise is generated.
[0003]
FIG. 7 is a cross-sectional view of a conventional anti-vibration mounting device (B), in which the hook-shaped mounting portion (112) of the drain side cylinder (101) is sinked by the tightening member (113) via the rubber packing (111). It is fixed to the drain port (110) of (109). On the other hand, the disposer side cylinder (102) is screwed to the upper end of the disposer (108), and the lower end of the drain port attachment cylinder (101) and the upper end of the disposer side cylinder (102) are rubber. Connected by the cylinder (114), the disposer (108) is supported in a state of being suspended from the disposer side cylinder (102).
[0004]
In the disposer (108), not only vegetable scraps but also pointed fish bones and hard bird bones etc. are thrown away as garbage without any distinction and are finely crushed by the disposer (108) Will be discharged together. The noise is generated when the amount of input to the disposer (108) is large and the load is excessive, or when the disposer (108) crushes hard fish bones or hard bird bones.
[0005]
In such a conventional anti-vibration device (B), fish bones and birds that have been thrown into the disposer (108) through the universal lid (115) provided on the drain side cylinder (101) The hard garbage such as the bones directly contacts the rubber cylinder (114) so that the rubber cylinder (114) is not torn and the load of the disposer (108) and the load of the input garbage and the disposer at startup Since it is necessary to withstand the torsional force of (108), a hard rubber material had to be used to some extent. Then, the vibration generated when the disposer (108) is operated is transmitted to the drain side cylinder (101) through the rubber cylinder (114), which is transmitted to the sink (109) and generates noise. The soundproofing effect was not achieved as expected.
[0006]
Therefore, a vibration isolator (C) as shown in FIG. 8 has been proposed. That is, the connection between the drain-side cylinder (201) and the disposer-side cylinder (202) is connected by a flexible rubber cylinder (214) having a bellows part in the middle, and the drain-side cylinder (201 The suspension member (205) is elastically suspended by the elastic suspension member (206) on the suspension member (204) extended from the above, and the drain side cylinder (201) is further extended. Therefore, it is located inside the flexible rubber cylinder (214). As a result, the flexible rubber cylinder (214) is protected by the extended portion (201a) of the drain outlet side cylinder (201) and the load is supported by the elastic suspension member (206). Therefore, the flexible rubber cylinder (214) can be formed of a softer rubber than the first conventional example, and the vibration is sinked through the hard rubber cylinder (114), which is a problem of the first conventional example. 109) The phenomenon of being transmitted to some extent has been resolved.
[0007]
However, the upper and lower ends of the flexible rubber cylinder (203) are fixed to the disposer side cylinder (202) and the drain outlet side cylinder (201) by bands (209) and (210), respectively. Therefore, vibration when the disposer (208) is operated is transmitted through the flexible rubber cylinder (203) itself and is transmitted from the disposer side cylinder (202) to the drain outlet side cylinder (201), thus preventing the vibration. The vibration effect could not be solved sufficiently.
[0008]
[Problems to be solved by the invention]
The present invention has been made to solve such a problem of the conventional example. First, by first cutting the edges of the disposer side cylinder side and the drain side cylinder body, vibration transmission can be minimized. The development of such an anti-vibration mounting device is a problem to be solved.

[0020]
The disposer side cylinder (2) includes a ring holding cylinder (54) into which the lower cylinder main body (33) is inserted, and an attachment uneven part (61) formed at the lower part of the ring holding cylinder (54). It consists of an attached metal ring (55). A concave groove (62) into which a later-described elastic ring (3) is fitted is formed in the central portion of the ring holding cylinder (54). In addition, the gap (K) between the ring holding cylinder (54) and the lower cylinder body (33) is closed over the entire circumference between the ring holding cylinder (54) and the lower cylinder body (33). A deodorizing elastic cylinder (58) formed of a very soft rubber film or resin film is disposed, and its upper and lower ends are fastened and fixed by bands (59) and (60).
[0021]
The elastic ring (3) fitted in the concave groove (62) is made of very soft rubber or elastic resin, and its inner periphery is axially and circumferentially aligned with the outer periphery of the lower cylindrical body (33). Is slidably in contact with The cross section of the elastic ring (3) is, of course, a hollow circle in this embodiment, but is not limited to this, and may be a solid circle or other rectangular cross section, and the cross sectional shape is not particularly limited. In this case, however, the inner circumference of the elastic ring (3) and the outer circumference of the lower cylindrical body (33) are in soft contact so that the vibration of the disposer (8) is not transmitted to the lower cylindrical body (33) as much as possible. It is desirable that
[0022]
In the embodiment shown in the figure, the elastic ring (3) is shown fitted in the groove (62) formed in the ring holding cylinder (54). It may be formed in the cylindrical body (33) and may be fitted into the lower cylindrical body (33), or may not be provided with the concave groove (62) as shown in FIG. 4, and the lower cylindrical body (33) and the ring holding cylindrical body The elastic ring (3) may be arranged to be able to roll in the gap (K) between (54). In any case, it is sufficient that the vibration transmission from the elastic ring (3) to the lower cylinder body (33) is minimized.
[0023]
Next, the suspended member (5), in the case of FIG. 1, the suspended member (5) is mounted on the ring holding cylinder (54) through the mounting uneven portion (61) via the metal ring (55). It is composed of a ring-like suspended connection outer casing (65) that is engaged with. A hooked convex part (57) having hooked grooves (56) formed in two places or three places at equal intervals at least symmetrically on the lower edge of the hooked side connecting outer rod (65). The latching claw (83) of the fastening member (82) rotatably attached to the elastic packing member (81) attached to the upper end of the disposer (8) It has become. In this embodiment, the fastening structure of the fastening member (50) to the connecting outer rod (41) and the fastening structure of the fastening member (82) to the suspended member (5) are the same structure. The fastening member (82) is rotated in one direction (clockwise when viewed from below), and the latching claw (83) is engaged with the latching groove (56) and tightened together. It is possible to strongly press the suspension-side connecting outer flange (65) against the mounting uneven portion (61) through the metal ring (55), and at the same time, attach the upper end inner peripheral surface of the elastic packing member (81) to the mounting uneven portion. The lower surface of (61) is pressed strongly, so that the suspended side connecting outer rod (65) and the fastening member (82) can be integrated.
[0024]
The elastic suspension member (6) includes a ring-shaped elastic seat (66) fitted in the through hole (39) of the lower piece (38) of the suspension-side arm member (37), and the suspension-side connection outer casing. The suspension bolt (67) planted in (65), the spring mounting uneven part (69) and the elastic seat (66) formed on the lower surface of the head (68) of the suspension bolt (67) are elastically contacted A suspension spring (70) disposed between the ring (69) and the ring (69). The elastic seat (66) is made of soft rubber so that vibration on the disposer (8) side is not transmitted to the suspension side arm member (37) via the suspension spring (70). The suspension bolt (67) is inserted into the through hole (71) so as not to contact the inner peripheral surface of the through hole (71) of the elastic seat (66). All the loads on the disposer (8) side are carried by the elastic suspension member (6).
[0025]
Further, between the suspension member (4) and the suspended member (5), at least two symmetrical positions between the elastic suspension members (6) or equidistant as shown in FIG. The anti-rotation member (7) is installed in three places. The anti-rotation member (7) is for stopping twisting at the start of the disposer (8), and FIG. 1 shows one embodiment thereof. That is, an anti-rotation cylinder (72) is secured to the lower surface of the suspension ring body plate (46) by a bolt (75). Corresponding to the ring-shaped detent mounting plate (77) fixed together with the suspended side outer flange (65) of the suspended member (5) Is standing and secured with a nut (76). The inner diameter of the elastic cylinder (73) is larger than the diameter of the non-rotating bar (74), and the elastic cylinder (73) does not come into contact with each other except when a large torsional force is generated when the disposer (8) is started. Although the rotation preventing member (7) is installed in the figure, it is not always necessary, and is installed as necessary.
[0026]
(15) is a free lid, which is attached to the inside of the upper end of the lower cylindrical body (33), has a radial notch groove formed in the center thereof, and a notch piece (17) around the inlet (16). However, it is difficult for the thrown-in garbage to reverse. A closing lid (18) is detachably disposed above the universal lid (15). The closure lid (18) is a plate-like lid body (18a), a knob (18b) attached to the center of the lid body (18a), and a ring-shaped latch attached for the peripheral portion of the lid body (18a). The ring-shaped locking portion (18a) is placed on the mounting uneven portion (31) of the drainage upper cylinder (21).
[0027]
Next, the operation of the first embodiment (A1) will be described. When kitchen work is done, garbage such as vegetable scraps, fish bones and bird bones is generated in large quantities. Therefore, the closing lid (18) is opened and the garbage is put into the disposer (8) through the free lid (15). Then, the suspension spring (70) is bent according to the weight of the garbage, and at the same time, the elastic ring (3) slides slightly on the outer peripheral surface of the lower cylindrical body (33). After that, when the closing lid (18) is closed and the switch is turned on, the motor (not shown) of the disposer (8) operates to rotate the hammer (not shown), and the raw material put into the disposer (8) is turned on. Garbage is pressed against a fixed blade (not shown) and crushed, and flows into sewage with water.
[0028]
When the motor is started, a large torsional force is generated in the disposer (8), and the portion below the ring holding cylinder (54) tends to rotate greatly with respect to the fixed lower cylinder body (33). In particular, depending on the position of the garbage thrown into the disposer (8), the center of gravity may be off-center and decentered. In such a case, the conventional disposer (108) was simply swung by the rubber cylinder (114) or the elastic suspension member (206), so that it was shaken greatly, but in the case of the present invention, the elastic ring ( Since 3) is in contact with the outer peripheral surface of the lower cylinder body (33), the amount of bending of the elastic ring (3) is limited, and even in such a case, the disposer (8) is not greatly shaken.
[0029]
Further, when the anti-rotation member (7) is provided, the anti-rotation rod (74) comes into contact with the elastic cylinder (74) on the inner peripheral surface of the anti-rotation cylinder (72) due to the presence of the anti-rotation member (7). Occurrence of torsion beyond the clearance between the body (74) and the non-rotating bar (74) is suppressed.
[0030]
During this time, the vibration generated by the disposer (8) is transmitted to the elastic ring (3), the suspension outer rod (65) and the suspension bolt (67) through the ring holding cylinder (54). Then, it is also transmitted to the elastic cylinder (73) through the anti-rotation rod (74). Since the elastic cylinder (73) is made of very soft rubber or resin, the vibration transmitted to the anti-rotation rod (74) is almost absorbed by the elastic cylinder (73), and the anti-rotation cylinder ( 72) Almost no transmission to the side. Further, since the elastic ring (3) is merely in sliding contact with the outer periphery of the lower cylinder body (33) by line contact, vibration transmission from here to the lower cylinder body (33) is extremely limited. It will be. Furthermore, the vibration transmitted to the suspension bolt (67) is suppressed by the suspension spring (70), but at the same time, the vibration transmitted to the suspension spring (70) itself carries the suspension spring (70). It is absorbed by the elastic seat (66) and hardly transmitted to the suspension side suspension member (37) side.
[0031]
Further, in the case of FIG. 1, when the above-described rotation preventing member (7) is not provided, the suspension bolt (67) contacts the inner peripheral surface of the elastic seat (66), and the elastic seat (66) is prevented from rotating. Since it plays the same role as the prevention member (7), it is preferable to use rubber or resin as soft as possible for the elastic seat (66).
[0032]
As described above, the large vibration and torsion that occur when the disposer (8) is started are blocked by the elastic ring (3), the anti-rotation member (7), and the elastic suspension member (4). Transmission to the 1) side is suppressed as much as possible, and the noise at the time of start-up is suppressed.
[0033]
When the rotation of the motor of the disposer (8) reaches a steady state, the torsional force disappears and returns to the original position by the force of the suspension spring (70), and the rod (74) from the elastic cylinder (74) After that, vibration isolation is performed exclusively by the suspension spring (70). During this time, while the disposer (8) is operating, vibrations with a high frequency are always generated, but effective vibration isolation is performed by the suspension spring (70). During that time, the elastic ring (3) is in line contact with the outer peripheral surface of the lower drainage cylinder (22) as described above. It will be very small.
[0034]
In addition, when a hard object such as a bone is crushed, a large vibration is generated. This vibration is also effective for vibration isolation by the suspension spring (70) as described above, and at the same time, drainage from the elastic ring (3). Transmission of vibration to the lower cylinder (22) is extremely small. Therefore, during a series of operations from starting to stopping of the disposer (8), most of the vibration generated in the disposer (8) is interrupted halfway and hardly transmitted to the sink (9) side, resulting in noise. There is nothing.
[0035]
FIG. 2 shows a second embodiment of the present invention. The only difference is the elastic suspension member (4). In this case, the elastic suspension member (4) is provided on the suspension-side connecting outer rod (65) so as to coincide with the suspension-side arm member (37) and the suspension-side arm member (37). The substantially U-shaped suspension-side arm member (52), the elastic members (66) (78) and the elastic seats (66) are fitted into the through holes (39) and (63) of both arm members (37) and (52). ) (78) and a suspension spring (70). The suspended side arm member (52) is fixed to the suspended side connection outer casing (65) with a mounting bolt (64). Similarly to the suspension side arm member (37), the suspension member (5) may be integrally configured by bending a part of the suspension side connection outer casing (65).
[0036]
Also in this case, the vibration isolating effect is the same as that of the first embodiment. However, since there is no suspension bolt (67), the disposer (8) side will be twisted more than necessary if a large twist occurs due to the disposer (8), so the installation of the rotating stop member (7) is indispensable It is.
[0037]
FIG. 3 is a third example showing the relationship between the elastic ring (3), the lower drainage cylinder (22) and the ring holding cylinder (54). The lower drainage cylinder (22) and the ring holding cylinder (54) are shown in FIG. In this case, the groove (62) is not formed in either case, and the elastic ring (3) is simply placed between the lower drainage cylinder (22) and the ring holding cylinder (54) so that it can roll. The elastic ring (3) is in line contact with both the lower drainage cylinder (22) and the ring holding cylinder (54), and the transmission of vibration is substantially blocked at this portion.
[0038]
5 and 6 show another embodiment of the rotation prevention member (7). In the case of FIG. 5, the rotation prevention cylinder (72) is made of rubber or soft resin, and the rotation prevention rod (74) Fixing the rubber rod or soft resin insertion rod (74a) and the insertion rod (74a) inserted into the rotation prevention hole (72a) of the rotation prevention cylinder (72) to the rotation prevention mounting plate (77) In this example, it is constituted by a bolt (74b). In this case, since the elastic bodies are in contact with each other, the transmitted vibration is smaller than that of the detent member (7) of the first embodiment.
[0039]
In FIG. 6, an elastic cylinder (73) made of rubber or soft resin is attached in a rotation prevention hole (72a) of a metal rotation prevention cylinder (72), and the rotation prevention rod (74) is made of this elasticity. It consists of a metal insertion rod (74a) inserted into the cylinder (73) and a rubber or soft resin fixing member (74d) that fixes the metal insertion rod (74a) to the non-rotating mounting plate (77). In this case as well, since the edge of the metal insertion rod portion (74a) is cut from the anti-rotation mounting plate (77) by the fixing member (74d) made of rubber or soft resin, the transmitted vibration is also the first embodiment. It becomes smaller than the anti-rotation member (7) in the example.
[0040]
【The invention's effect】
In the present invention, since the elastic ring is arranged so as to be able to roll without being fixed between the gap provided between the drain side cylinder and the disposer side cylinder, the drain side The edge between the cylinder and the disposer-side cylinder can be cut, and the vibration transmitted from the disposer-side cylinder is blocked by the elastic ring, which hardly transmits to the drain-side cylinder and greatly enhances the vibration isolation effect. Can do. Further, by providing the rotation preventing member, it is possible to suppress torsional deformation of the disposer side cylinder relative to the drain outlet side cylinder at the time of starting the disposer to a certain limit. Furthermore, the elastic ring has a circular cross section, and can be slidably brought into contact with either the drain-side cylinder or the disposer-side cylinder to cut almost the edge between the drain-side cylinder and the disposer-side cylinder. It is possible to eliminate the transmission of vibration from the disposer side cylinder side to the drain port side cylinder side.
