In which the two are joined. These joints 10
5, 210 has a structure in which a pair of bevel gear-shaped disks face each other and mesh with each other.

It should be noted that instead of such a type of joint, 1
A universal joint or a flexible joint that can transmit power reliably even if it is somewhat eccentric can be used as a joint that transmits power with a pair of magnets facing each other. Also, without using the shaft sealing device 209, the upper end of the rotary drive shaft 208 of the electric motor 201 and the screw 10
A magnet is attached to the lower end of the rotating shaft 104 on the eight side, and both magnets are shielded by a non-magnetic material such as a stainless steel plate, and both are brought close to each other. It is also possible to use a magnet coupling that transmits the rotation to the driven rotation shaft 104 to which the screw 108 and the like are attached.

The shaft sealing device 209 and the electric motor 201
Between them, a rubber disk 211 is mounted on the rotary drive shaft 207 so that even if water leaks from the shaft sealing device 40, a water accident in the motor 2016 does not occur.

Next, the processing operation of the processing apparatus thus configured will be described.

The garbage charged into the charging port 112 is caught by the rotation of the screw 108, and is quickly conveyed to the crushing mechanism 130 while being compressed. The screw 108 is formed to have a slightly smaller diameter at the top and to gradually increase the pitch upward, in order to easily catch the garbage, and the transfer passage 113 has an inverted conical shape as described above. It is formed in a tubular shape. Also, the inner cylinder 10
A projection 117 extending in the axial direction is provided on a portion of the inner wall 111 facing the side surface of the screw 108 so as to increase resistance to prevent the kitchen waste from rotating together with the screw 108. A spiral groove may be provided in place of the projection 117, the garbage passage 113 may have a non-circular cross-sectional shape such as a rectangular shape, or the axis of the rotation axis of the screw 108 may be eccentric with respect to the garbage passage 113 so that the inside of the garbage and the garbage are separated. It is possible to increase the friction between the inner wall surface 111 and the co-rotation of the garbage. Note that it is sufficient to prevent the co-rotation if the shape of the kitchen waste passage 113 of the inner cylinder 101 in which the transfer mechanism 140 is stored is substantially non-uniform with respect to the outer peripheral locus of the screw 108. is there.

The garbage that has reached the crushing mechanism 130 via the transfer mechanism 140 thus configured is finely crushed and cut by the rotating blade 107 and the fixed blade 106 in the crushing mechanism 130, and then the garbage is fixed. Kitchen garbage discharge hole 1
It is extruded from 10 to the lower flow path 206 side, and is discharged together with drainage to a lateral discharge port 205.

In this example, the screw 108 and the rotary blade 1
07 is smaller than the diameter of the inlet 112 and the transfer passage 11
3 is also formed in an inverted conical shape, and the cross-sectional area is set to be smaller toward the lower part, so that only a small amount of water is injected during crushing, and water and garbage are transferred to the lower crushing mechanism 130 part. Guided promptly. For this reason, water can be saved at the time of processing the garbage, and the compressed garbage is crushed. At this time, the crushing mechanism 130 can be submerged by injecting a small amount of water, the crushing sound can be shielded by water, and the noise can be reduced. In addition, soft and long items such as squid and fibrous materials, which are considered difficult to treat in the prior art, are forcibly guided to the crushing position by the screw 108 and compressed to minimize the space between the kitchen wastes. It can be crushed reliably and quickly.

On the other hand, drainage discharged in the sink 300 during normal cooking flows down in the transfer passage 113 to wash the transfer mechanism 140 and the crushing mechanism 130 while the fixed blade 1
06 through the opening 106a (FIG. 3) through the flow path 206 to the discharge port 205. When the amount of drainage is large, the flow path passes through the communication path 116 from the opening 114 of the inner cylinder 101 to the outside. Outflow to 206. Since the filter 114 is provided in the opening 114, relatively clean water flows from the communication path 116 to the flow path 206 side. Thereby, the shaft sealing device 209 and the joints 105 and 210 are always washed to maintain good water sealing, and the drainage is also performed from the opening 106a located on the upstream side of the discharge port 205 with respect to the rotary drive shaft 207. Kitchen waste can be smoothly discharged toward the discharge port 205.

When the drainage is overflowed so as to overflow the inner cylinder 101, the communication path 116 between the inner cylinder 101 and the outer cylinder 102 is filled with water, and the periphery of the crushing mechanism 130 is surrounded by water. The sound during crushing will be shielded by water. In such a situation, the noise is minimized and the noise level during operation is ensured by several decibels to 10 dB.
Can be reduced by about a decibel.

As described above, the inner cylinder 101 is removably mounted between the cylinder 303 and the housing 202, and the joints 105 and 210 only mesh with each other in the rotation direction. Sealing body attached to inner edge 06
Is removed, the upper end edge of the inner cylinder 101 is opened, and the inner cylinder 101 can be integrally taken out from the drain port 302 of the sink 300 with the transfer mechanism 140 and the crushing mechanism 130 attached. .

Also, by removing the C ring 109,
The screw 108 and the rotary blade 107 can be removed from the driven rotary shaft 104. Therefore, when removing foreign matter such as a spoon that has fallen from the insertion port 112 by mistake, it is possible to remove only the screw 108 and remove the foreign matter, and also to easily perform cleaning and inspection. At this time, there is no need to disassemble the main body portion of the kitchen waste treatment apparatus such as the outer cylinder 102 and the housing 202, so that the work can be performed sanitarily and easily without leakage of kitchen waste and sewage to the outside.

When the inner cylinder 101 is configured to be divided into a plurality of parts (for example, two or four in the axial direction), even if the screw 108 is locked by a solid material, a part of the inner cylinder 101 can be removed. , The locked solid matter can be easily taken out.

The screw 108 or the rotating shaft 1
When an engagement portion 118 such as a groove that engages with a tool such as a screwdriver is provided at the upper end of the tool 04, when the rotation shaft 104 is locked by a foreign object, a tool is inserted from the insertion port 112 and the sink 300 is inserted from above. Work for unlocking can be performed.

Further, when the kitchen waste treatment apparatus 1 cannot be operated due to a power failure or the like, the screw 108 or the inner cylinder 10
1 by removing the entirety and mounting a commercially available bag for collecting garbage or a net basket in the transfer passage 113 in the inner cylinder 101 or the communication passage 116 in the outer cylinder 102, so that the conventional sink can be used as an emergency. It can be used in the same way as the drain.
