Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposal apparatus for crushing garbage discharged from a kitchen and flowing the garbage to a sewer.

[0002]

2. Description of the Related Art FIG. 2 is a front view of a conventional kitchen garbage disposing apparatus in which a part thereof is cut away and attached to a sink.
Reference numeral 1 denotes a garbage disposal apparatus, and an upper casing 11 and a lower casing 12 are connected by a connecting portion 14. A housing 13 for hermetically housing a motor, which is a rotary driving device, is provided below the lower casing 12. Furthermore,
A drain pipe 15 is connected to the side of the lower casing 12 via packing and mounting bolts.

[0003] The kitchen waste treatment apparatus 1 is attached to a sink 4 via a sink flange 2, a packing 5, a fastening nut 6, and a connecting member 3. The maximum outer diameter D2 of the kitchen waste disposal apparatus is a connecting portion 14 that connects the upper casing 11 and the lower casing 12, and the maximum outer diameter D2.
Is larger than the inner diameter d2 of the screw portion of the tightening nut 6. Therefore, when the kitchen waste treatment apparatus 1 is to be mounted on the sink 4, the sink flange 2 is first fitted into the mounting hole 16 of the sink 4 from above, and the sink flange 2 is inserted from the lower part of the sink 4.
And tighten the fastening nut 6 to the male screw portion 21 of the above. The packing 5 prevents water leakage.

Next, as shown in FIGS. 3 and 4, the kitchen waste treatment apparatus 1 and the sink flange 2 are connected to each other by providing a conical taper portion 25 at a lower portion of the sink flange 2 and a lower portion of the sink 4 to the upper casing 11. A coupling member 3 composed of a pressing member 8, a pin member 9 and a retaining member 7 for inserting and coupling is provided at an upper portion of the upper casing 11, and a loosening position 22 is provided.
The locking portion 26 of the pin member 9 slides on the conical taper portion 25 by rotating the pressing member 8 having a sliding surface internally connected to the tightening position 23 by an arc so that the sink flange 2 is connected to the sink flange 2. The kitchen waste disposal apparatus 1 can be combined. Packing 1 at the same time
It has a structure that sandwiches 0 and prevents water leakage.

[0005]

However, in the above-mentioned conventional garbage processing apparatus, since the maximum outer diameter D2 of the garbage processing apparatus 1 is larger than the inner diameter d2 of the screw portion of the tightening nut 6, the garbage processing apparatus 1 is attached to the sink 4. In such a case, the kitchen waste disposal apparatus 1 must be attached from the lower part of the sink 4 and the narrow sink 4
There was a problem that the work at the lower part of the work was difficult.

The present invention has been made to solve such a conventional problem, and an object of the present invention is to provide a garbage disposal apparatus which can be easily attached to a sink.

[0007]

The garbage disposal apparatus according to the present invention is characterized in that the maximum outer diameter of the garbage disposal apparatus is formed to be smaller than the inner diameter of the screw portion of the tightening nut.

[0008]

By setting the maximum outer diameter of the garbage disposal device to be smaller than the inner diameter of the screw portion of the tightening nut as described above, the garbage disposal device can be fitted into the mounting hole of the sink from above the sink. It becomes possible.

Furthermore, by integrally forming the drainage pipe with the lower casing to enable the above-mentioned mounting method, water leakage is completely prevented, and work at the lower part of the sink becomes extremely simple.

In addition, the above-described mounting method enables the sink flange and the upper casing of the garbage disposal apparatus to be integrally formed, and a connecting member having a complicated mechanism can be eliminated, so that an inexpensive garbage disposal apparatus can be provided. .

[0011]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a partially cutaway front view of a kitchen waste disposal apparatus according to one embodiment of the present invention. This garbage processing apparatus is basically the same as a conventional garbage processing apparatus, and therefore, the same members have the same reference numerals and their details are omitted.

The garbage processing apparatus of this embodiment differs from the conventional one in that the maximum outer diameter D1 of the garbage processing apparatus is smaller than the inner diameter d1 of the screw portion of the tightening nut 6. By making the maximum outer diameter D1 of the garbage disposal apparatus smaller than the inner diameter d1 of the screw portion of the tightening nut 6, the garbage disposal apparatus can be attached to the sink 4 from above.

Hereinafter, a mounting method according to this embodiment will be described. The garbage disposal device 1 provided with the sink flange 2 and the drain pipe 15 is fitted into the mounting hole 16 of the sink 4 from above the sink 4, and the nut 6 is screwed into the male thread portion 21 of the sink flange 2 from below the sink 4. To complete the installation work.
The packing 5 is interposed between the sink flange 2 and the sink 4 to prevent water leakage. Further, the drain pipe 15 is formed integrally with the lower casing 12.

As described above, the maximum outer diameter D1 of the kitchen waste treatment apparatus
Is made smaller than the inner diameter d1 of the screw portion of the tightening nut 6, so that the kitchen waste disposal apparatus can be attached from the upper part of the sink 4, and the sink flange 2 can be attached from the lower part of the sink 4.
It is only necessary to tighten the tightening nut 6 to the male screw portion 21 of the above, and the mounting work becomes extremely simple.

[0015]

As described above, according to the present invention, since the maximum outer diameter of the garbage disposal device is made smaller than the inner diameter of the screw portion of the fastening nut, the garbage disposal device can be mounted from the upper surface of the sink. And the mounting work becomes extremely easy. Further, it is possible to prevent water leakage from the drain pipe and to eliminate a connecting member having a complicated mechanism, so that an inexpensive garbage disposal device can be provided.
