DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disposer for crushing and dewatering kitchen waste such as vegetable waste and fish bones, and more particularly to a crushing mechanism.

[0002]

2. Description of the Related Art Heretofore, as a disposer for crushing and dewatering kitchen garbage such as vegetable waste and fish bones, there has been disclosed a disposer having a crushing mechanism as shown in FIGS. JP-A-55-155751). That is, reference numeral 100 denotes an upper casing having an inlet 101 at an upper side and a crushing chamber 102 at a lower side. Reference numeral 103 denotes a lower casing having a discharge port 104, which is connected to a drive motor 105 below. A rotating shaft 107 inserted into the lower casing 103 via a shaft sealing device 106, and a rotating disk via a boss 108. 109, and a striking blade 110 fixed to the upper surface near the outer periphery of the rotating disk 109,
It faces a fixed blade 111 provided on the inner peripheral surface of the crushing chamber 102. With such a configuration, the garbage W inserted from the input port 101 falls on the rotating disk 109 rotated by the drive motor 105, and the garbage W is rotated by the centrifugal force of the rotating disk 109. The upper blade moves in the outer circumferential direction and crushes while hitting the striking blade 110, and is sent to the gap G between the striking blade 110 and the fixed blade 111 to be struck.
10 is cut by the outer surface and the fixed blade, falls into the lower casing 103 with water, and is discharged to the outside through the discharge port 104.

[0003]

However, in the above-described prior art, the gap G between the striking blade 110 and the fixed blade 111 is set to be constant. When the garbage W, such as relatively hard root vegetables, is mixed into the fixed blade 111 while the garbage W is not broken by the impact blade 110 and is sent to the fixed blade 111, the impact blade 11
There is a disadvantage that it takes a long time to crush the garbage W finely because only a small portion can be cut into between the zero and the fixed blade 111. Further, when a hard blocky foreign substance such as metal or stone is mixed, the impact blade 110 is fixed to the rotating disk 109, so that a large impact is applied to the impact blade 110, and since the gap G is small, the impact blade or the fixed Damaged or
The drive motor may be overloaded and burned out. SUMMARY OF THE INVENTION An object of the present invention is to provide a disposer having a high processing capability capable of increasing the degree of crushing of garbage and preventing damage to the blade and the drive motor even when foreign substances are mixed.

[0004]

2 is an intermediate casing, 3 is a lower casing, 4 is a drive motor connected to the lower casing and arranged with the rotating shaft 41 facing upward, 5 is a first crushing chamber in the upper casing 1,
Reference numeral 6 denotes a second crushing chamber provided in the intermediate casing 2, and reference numeral 7 denotes a discharge chamber formed by the lower casing 3. Reference numeral 51 denotes a first fixed blade ring provided inside the casing of the first crushing chamber 5,
A first fixed blade 52 including a plurality of protrusions is provided. 5
Reference numeral 3 denotes a first rotating disk mounted on the upper portion of the rotating shaft 41 via the boss 54 and disposed in the first crushing chamber 5 and rotatably supported on the upper surface near the outer periphery thereof via the supporting shaft 55. First
A striking blade 56 is provided, and a cutting blade 57 is provided on the outer surface of the striking blade 56. In the illustrated embodiment, two hitting blades are mounted on the first rotating disk 53. Reference numeral 58 denotes the first rotating disk 5 for returning the cutting blade 57 to the direction facing the first fixed blade ring 51 when the hitting blade 56 rotates.
3, for example, as shown in FIG.
The lever 59 attached to the support shaft 55 is pulled in the rotation direction of the first rotating disk so as to hit the stopper 60. Reference numeral 61 denotes an annular second fixed blade ring provided inside the intermediate casing 2 forming the second crushing chamber 6, and has a second fixed blade 62 inside. 63 is a second rotating disk attached to the lower part of the rotating shaft 41 via a boss 64, and has a larger diameter than the first rotating disk 53. Reference numeral 65 denotes a second striking blade fixed to the upper surface near the outer periphery of the second rotating disk 63, and has a cutting blade 66 on the outer surface. Reference numeral 8 denotes an inlet of the upper casing 1, and 9 denotes an outlet of the discharge chamber 7.

Next, the operation will be described. First, the first rotating disk 53 and the second rotating disk 63 are rotated by the drive motor 4, and when the garbage W is thrown into the first rotating disk 53 together with the water from the inlet 8 of the upper casing 1, The kitchen waste W is sent on the first rotating disk 53 by centrifugal force in the outer peripheral direction of the first rotating disk, crushed by the first striking blade 56, pressed against the first fixed blade ring 51, and pressed against the first striking blade 56. Is cut by the rotation of the cutting blade 57 and dropped from the gap G to the intermediate casing 2. In addition, even if the large garbage W and the garbage adhere to the first fixed blade ring 51 thickly even if the garbage is crushed by the collision with the first hitting blade, as shown on the right side of FIG. By rotating, the gap with the first fixed blade 52 is increased, the garbage W is pinched and rotated, crushed into a coarse state, and discharged into the second crushing chamber 6 below. Prevents damage to the striking blade and fixed blade without forcing crushing.
The gap between the fixed blade 52 and the kitchen waste W crushed into a coarse state in the first crushing chamber 5 is increased from the gap G to the second
It falls on the rotating disk 63, is crushed by the second striking blade 65 fixed to the second rotating disk 63, is sent to the second fixed blade ring 61 by centrifugal force, is pressed against the second fixed blade 62, and 2 The blade is finely cut and crushed by the rotation of the hitting blade 65, falls into the discharge chamber 7 of the lower casing 3 from the gap G ', and is discharged from the discharge port 9 to the outside.

[0008] Therefore, even if the lump of garbage W is put in, the crushing time is short and the processing capacity can be maintained high. If the put garbage contains a hard material such as stone or metal, The first striking blade 56 rotates to reduce the impact, the gap with the first fixed blade 52 increases, and the striking blade rotates beyond the foreign matter. Therefore, the load on the drive motor 1 increases, but since the first cutter 3 can swing around the support shaft 23, the first cutter 3 does not bite between the cutting blade 31 and the cutting blade 41, resulting in an overload. The drive motor 1 is not damaged.

[0009]

As described above, according to the present invention, the first
It has a crushing chamber and a second crushing chamber, and the garbage that has been roughly crushed and cut in the first crushing chamber is finely crushed and cut in the second crushing chamber, so that large lump garbage and hard-to-cut garbage can be finely crushed in a short time. can do. Further, since the first striking blade provided on the first rotating disk is rotatably supported, the first striking blade can be first fixed by turning the first striking blade even when a large lump of garbage or foreign matter is mixed. The gap with the blade ring can be automatically adjusted to ensure that the crushing will be performed by colliding over the lump of garbage again, and that the cutting blade and fixed blade will not be damaged without forcing foreign objects to bite. In addition, burnout of the drive motor can be prevented. Also, by forming the first crushing chamber smaller in diameter than the second crushing chamber, kitchen waste from the first crushing chamber can be reliably dropped on the second rotating disk, and the first fixed blade and the first hitting blade can be used. Is smaller than the gap between the second fixed blade and the second striking blade, so that the first crushing chamber can be roughly crushed and the second crushing chamber can be finely crushed. In addition, there is an effect that it is possible to easily crush massive garbage and to provide a disposer having a high processing capacity.
