Next, a garbage input port 10b which is a drainage port
The protector 5 mounted on the vehicle will be described in detail with reference to FIGS. 2A is a plan view in which a part of the protector 5 is broken, FIG. 2B is a front view in which a part of the protector 5 is broken, and FIG. 3 is a cover body fitted to a tubular body of the protector. It is a front view.

The protector 5 includes a cylindrical body 51 having a substantially cylindrical shape,
It is composed of a lid 61 that fits into the internal opening of the cylindrical body. The tubular body 51 is made of, for example, a synthetic resin such as polypropylene or nylon, has a flange portion 52 projecting outward at the upper end, and an edge portion 53 projecting inward at the lower end. The flange portion 52 of the cylindrical body 51 is the sink S.
It is configured so as to be engaged with the stepped portion of the drainage port and not fall into the crushing chamber 24. The cylindrical body 51 has a plurality of circular through holes 54 formed in the outer peripheral surface thereof. The through holes 54 are circular and are formed on the circumference of the lower part of the tubular body 51 so that four holes are opened at equal intervals in the horizontal direction. The clearance between the outer peripheral surface of the cylindrical body 51 and the food waste introduction port 10b is set to be large so that there is no problem such as contact even if the circularity of the cylindrical body is somewhat poor.

The lid 61 is made of an elastic material such as natural rubber or synthetic rubber, and is composed of a thick ring portion 62 on the outer circumference and a thin cover portion 63 formed continuously inside the ring portion 62. The portion 63 is formed by a conical surface that is inclined so that the center portion becomes low, and a through hole 64 is formed in the center.
A radial cut is formed in the thin cover portion 63, and a small-diameter through hole 65 is formed in the outer peripheral end of the cut. Therefore, the cover portion 63 is formed with twelve cover pieces 63a by radial cuts, and the cut pieces normally contact the cuts to close the inner opening of the cylindrical body 51. It is curved so that the notch opens and opens. After the garbage is put in, the cover piece 63a returns upward and closes the opening to prevent the fragments scattered during the crushing of the garbage. The central through hole 6
4 and the small diameter through hole 65 on the outer circumference may be omitted.

The outer diameter of the ring portion 62 of the lid 61 is equal to that of the tubular body 5.
1 is formed to be slightly larger than the inner diameter of the lid 1, and the lid 61 is attached to the cylinder 5
It is formed so as to be slightly compressed when it is fitted into the inside of the housing 1, and the lid 61 is closely attached to the tubular body 51. A plurality of protrusions are formed on the outer peripheral surface of the ring portion 62, and the four through holes 5 of the cylindrical body 51 are formed.
Four protrusions 66 corresponding to No. 4 are formed. The four protrusions 66 are columnar portions having an outer diameter smaller than the inner diameter of the through hole 54 and are formed larger than the wall thickness of the cylinder body 51. Therefore, the protruding portion 66 is loosely fitted into the through hole 54 of the tubular body 51, protrudes from the outer circumferential surface of the tubular body 51, and is elastically contacted with the inner circumferential surface of the food waste introduction port 10b. There is no rattling at the dust input port 10b. Further, the lower end surface of the ring portion 62 of the lid 61 is in contact with the edge portion 53 at the lower end of the tubular body 51.

The operation of the disposer of the present embodiment configured as described above will be described below. Disposer D
When using, the garbage is thrown in from the garbage throwing port 10b at the upper end opening of the fixing member 1 attached to the drain of the sink S, and the drive motor 3 is rotated while opening the tap of the tap water and pouring water. . Due to this rotation, the turntable 42 is rotated, and the swing hammers 43, 43 are unbalanced with respect to the fulcrum, so that the tooth portion having a large thickness is swung toward the outer periphery by the centrifugal force. For this reason, raw garbage is crushed in the crushing room 24.
In the inside, the turntable 42 and the swing hammers 43, 43 are blown to the outer peripheral side, hit the fixed teeth 41 and crush, and are crushed and crushed between the swing hammers 43, 43 and the fixed teeth 41. Grinded garbage is fixed teeth 4
1 falls into the discharge chamber 25 through the gap between the turntable 42 and the turntable 42, and is discharged through the drain pipe 6.

The protector 5 does not resonate due to vibration during crushing because the protrusion 66 of the lid 61 is in elastic contact with the food waste input port 10b. The crushed pieces of raw garbage are scattered even when directed upward, but since the raw garbage inlet 10b is closed by the cover piece 63a of the protector 5, it can be prevented from being scattered to the outside. It should be noted that since the scraps of the food waste are repelled by the turntable 42 in the outer peripheral direction, they do not fly out through the central through hole 64.

When removing the protector 5 from the garbage input port 10b, the cover piece 63a of the lid 61 of the protector 5 is lifted, and the projection 66 of the lid 61 is inserted into the garbage input port 1b.
The outer peripheral surface of 0b can be easily removed by sliding. That is, since the protector 5 and the food waste input port 10b are engaged with the flange portion 52 and are in contact with each other at four points of the protruding portion 66, and the clearance is large, the rubber of the protruding portion 66 swells to increase the volume. Can also be easily slid. Conventionally, for example, since the entire circumference of the O-ring is sandwiched between the food waste input port and the cylindrical body, it is difficult to adhere and remove it when it swells. However, in the present embodiment, the protector 5 has the food waste. The clearance is set to be large by making point contact with the insertion port 10b at the protrusion 66, and even if the protrusion swells, the protrusion 66 can be retracted toward the inside when pressed, so that the protector 5 can be easily removed. And protector 5 due to aging
Even if is deformed, it can be easily removed from the garbage input port.

This protector 5 can be attached to the drain port of the sink as a cover with the same structure. A sink sink S without a disposer D is usually
A mesh container (not shown) with a mesh structure below the drainage port
The cover lid (5) having the same structure as the protector 5 is fitted into the drainage port (10b) at the upper part of the waste container. The cover lid includes a tubular body 51 having a plurality of through holes on the outer peripheral surface thereof, and a lid body 61 formed of an elastic body such as rubber that covers the inner opening of the tubular body. In this case as well, the cover lid is made of an elastic body. The projecting portion 66 of the lid body formed in step 5 protrudes from the through hole 54 of the cylindrical body and makes elastic contact with the wall surface of the drainage port to form point contact.
Since the clearance between 1 and the garbage input port 10b is large, the cover lid can be easily removed from the drain port, and there is no problem even if it deforms due to aging. Further, since the lid body of the cover lid covers the upper portion of the dust container, it is possible to prevent the odor emitted from the dust from scattering to the outside.

Next, another embodiment of the present invention will be described with reference to FIGS.
It will be described in detail based on. 4 is a sectional view of another embodiment of the protector, and FIG. 5 is a bottom view of FIG. It should be noted that this embodiment differs from the above-described embodiments in that the guard bar 56 that crosses the inner opening integrally with the cylindrical body 51A of the protector 5A.
Is formed. Then, other substantially equivalent configurations are denoted by the same reference numerals, and detailed description thereof will be omitted.

In FIGS. 4 and 5, the protector 5A comprises a cylindrical body 51A and a lid 61, and the lid 61 has exactly the same construction as the above-mentioned embodiment. And the cylinder 51
In A, a thick-walled tubular portion 55 is continuous below the lid 61, and a guard bar 56 that crosses the internal opening is integrally formed in the tubular portion with a synthetic resin. Also in this embodiment, the protector 5A is the same as the protector 5 of the above-described embodiment.
Has a configuration in which the protrusion 66 elastically contacts the food waste input port 10b, and can be easily removed from the food waste input port 10b. Further, even if the protector 5A is deformed over time, it can be easily removed.

Further, in this embodiment, since the guard bar 56 that crosses the inner opening is formed integrally with the cylindrical body 51A, when the hand is inserted into the garbage input port 10b, it hits the guard bar 56 and accidentally enters the crushing chamber 24. It is possible to prevent the insertion of the hand. Further, since the guard bar 56 can be formed integrally with the tubular body 51A, the number of parts can be reduced and the cost can be reduced. When the protector 5A is removed from the food waste input port 10b, the guard bar 56 is located when the cover piece of the lid 61 is opened. Therefore, the guard bar 56 can be easily removed by pinching and pulling up. The guard bar 56 can be formed very easily without using a slide die by simply digging a groove in the die when injection molding the cylinder 51A.

Although the guard bar is formed of one rod which crosses the inner opening of the cylindrical body, the two bars intersect at a right angle in the center of the inner opening, or they intersect at an angle of 120 degrees. It may be a stick of a book. As the synthetic resin constituting the protector, in addition to the above-mentioned ones, an appropriate resin such as ABS resin, polyethylene resin, polystyrene resin can be used. Further, the protector 5A shown in FIGS.
Attached to the drain port of the sink as a cover to cover the cylinder 51A.
May be used to cover the inner opening of the sink and cover the drain of the sink.

[0032]

As can be understood from the above description, in the disposer of the present invention, the protector fitted in the garbage disposal can be easily removed, and the protector can be easily deformed or swollen due to aging. It can be removed. Further, since the guard bar is integrally formed on the cylindrical body of the protector, it is possible to prevent accidental insertion of a hand into the crushing chamber. Since the lid covers the garbage input port, noise during crushing can be reduced and scattering of crushed pieces of garbage can be prevented. The cover lid of the present invention can be easily removed from the drain port of the sink, and can be easily removed even if it is used for a long period of time and changes with time.
