2. Description of the Related Art In the prior art of a garbage disposal apparatus, for example, a rotary blade attached to a rotary plate while continuously injecting tap water from a garbage inlet as shown in Japanese Patent Application Laid-Open No. 59-203651. Some crush the kitchen garbage and let it flow down to the lower outlet through the holes in the rotating plate. In such a conventional technique, in a crushing chamber configured to have a larger diameter than the kitchen refuse inlet, a part of the garbage crushed by the rotary blade is scattered and adhered to the inner wall by the centrifugal force of the rotating plate, and a small amount of Since it is difficult to be discharged by water injection, it has a problem that it rots and emits a bad smell, and is solidified in a narrow opening or a shaft sealing device to hinder drainage and crushing action.

[0003] Further, when cleaning the inside or removing clogged foreign substances, it is necessary to remove the garbage disposal device from the sink and disassemble it, so that there is also a problem in handleability such as leakage of sewage to the outside. . Also, even if you insert your hand to take out tableware such as a spoon that was accidentally thrown in,
There is a problem in terms of safety, for example, it is necessary to take measures to prevent damage to the rotating blade rotating at high speed.

[0004]

The garbage disposal apparatus according to the present invention is an improvement over the prior art, and provides a method for crushing and handling garbage.
In addition, it aims to improve safety.

[0005]

The object of the present invention is to provide, for example, a transfer mechanism or a crushing mechanism driven by an electric motor downstream of an input port for kitchen garbage, and arbitrarily transmit power between the electric motor and the transfer mechanism or the crushing mechanism. The problem can be solved by providing a transmission mechanism for connection or disconnection.

That is, the garbage dropped from the input port is finely crushed by a transfer mechanism or a crushing mechanism driven by an electric motor and quickly pushed out to the discharge port. In addition, the transfer mechanism or the crushing mechanism can be taken out from the input port by arbitrarily connecting or disconnecting the transfer mechanism or the crushing mechanism and the electric motor with a detachable power transmission mechanism, and disassembling the main body of the garbage disposal apparatus. Without leaking sewage to the outside,
Internal cleaning inspection and removal of foreign substances can be performed safely.

Next, the present invention will be described in detail with reference to an embodiment.

FIG. 1 shows a kitchen waste disposal apparatus having a food waste inlet 4 on the bottom surface of a sink 2 of a sink, a transfer mechanism 7 driven by an electric motor 6 and a crushing mechanism 8. A flanged cylindrical body 10 and an annular body 12 are screwed into the inlet 4, and the bottom surface of the sink 2 is watertightly clamped via an annular packing 14. An annular sealing member 15 made of an elastic material is provided in the opening of the cylindrical body 10.
Is attached, and the plug 16 is detachably attached thereto. Further, the plug 16 is provided with a water inlet 16A having a flow area smaller than that of the inlet 4, and a small amount of water to be injected for smoothing the flow of garbage during crushing is supplied to the water inlet 16A. By filling, the inside of the sink 2 and the crushing mechanism 8 are shut off with water, so that the crushing sound is prevented from leaking out of the inlet 4 to reduce noise. In addition, water inlet 1
When water is not flowing into the 6A, the sink 2 and the crushing mechanism 8 are communicated with air, and the crushing sound is heard from the water inlet 16A in a correspondingly large size, so that the water was forgotten to be injected. The effect of the warning action to pay attention to the person is also obtained.

An outer cylinder 19 is attached to the lower part of the cylindrical body 10 in a watertight manner by a union nut 21 via a sealing body 20. Further, a housing 22 to which the electric motor 6 is attached is mounted below the outer cylinder 19 via a sealing body 24.

An inner cylinder 25 is mounted from the input port 4 toward the housing 22, and a transfer mechanism 7 is provided inside the inner cylinder 25.
And a crushing mechanism 8. The rib-shaped locking portion 25A at the upper part of the inner cylinder 25 is engaged with the groove 10A of the cylinder 10, thereby preventing the transfer mechanism 7 and the inner cylinder 25 from rotating together during crushing. The lower part of the inner cylinder 25 is the outer cylinder 19.
The lower part of the inner cylinder 25 and the outer cylinder 19
A pressing spring 18 is mounted between the bottom and the bottom. In the figure, the inner cylinder 25 is pressed downward by the attachment of the plug 16 in accordance with the repulsive force of the pressing spring. The transfer mechanism 7 includes a screw 26 and a driven shaft 2.
7 is mounted by a method such as a key, a spline, or a screw, and the C ring 28 is mounted on the distal end of the driven shaft 27, so that the screw 26 can be detached from the inner cylinder 25 only in the axial direction. It is configured as follows. Alternatively, the screw 26 and the driven shaft 27 may be formed integrally. A rotary blade 30 shown in FIG.
Are mounted so as to be slidable only in the axial direction of the driven shaft 27. Below the rotary blade 30, a fixed blade 32 is detachably fixed to the inner tube 25 so as to face and oppose. A gap 36 communicating with the discharge port 34 is provided below the fixed blade 32. Is provided. The driven shaft 27 is rotatably supported on the inner cylinder 25 by a bearing 37 with a filter, and has a lower end protruding into the gap 36. On the other hand, the electric motor 6
The shaft sealing device 40 is mounted on the rotary shaft 6A, and the upper end protrudes into the gap 36. Upper end of rotating shaft 6A and driven shaft 27
And a lower end portion of the power transmission mechanism 7 is connected by a detachable joint 41 to form a power transmission mechanism for transmitting the rotational force of the electric motor 6 to the upper transfer mechanism 7 and the crushing mechanism 8. In the embodiment, a joint 41 having a structure in which a pair of bevel gear-shaped disks are opposed and meshed with each other.
However, for example, a detachable joint structure in which a pair of permanent magnets are opposed to each other, a universal joint structure in which two axes slightly eccentric are connected, or a flexible joint structure may be used. Alternatively, without using the shaft sealing device 40, permanent magnets are attached to both shaft ends of the rotating shaft 6A and the driven shaft 27 of the electric motor 6, and both magnets are shielded by a non-magnetic material such as a stainless steel plate while being close to each other. A magnet joint that opposes and transmits the rotational driving force of the electric motor 6 to the driven shaft 27 by a magnetic force may be used. On the other hand, between the shaft sealing device 40 and the motor 6, a rubber disk 42 is mounted on the rotating shaft 6 </ b> A, and even if water is leaked from the shaft sealing device 40, water is prevented from entering the motor 6. To prevent. Further, an inner cylinder 25 is provided between the cylinder 10 and the housing 22.
, A communication passage 46 extending from the filter-equipped opening 25 </ b> B to the gap 36 is formed separately between the outer cylinder 19 and the inner cylinder 25. You.

Next, the processing operation of the kitchen waste processing apparatus will be described. The garbage introduced into the passage 45 from the introduction port 4 is caught downward by the rotation of the screw 26, and is quickly conveyed to the crushing mechanism 8 while being compressed. Here, in order to make it easier to catch the kitchen waste, the screw 26 is formed so that the upper part has a slightly smaller diameter and the pitch gradually increases toward the upper side, and the passage 45 gradually decreases downward. It is formed to be narrow. In the crushing mechanism 8, the garbage is finely crushed and cut by the rotary blade 30, and then pushed out from the opening 32 </ b> A of the fixed blade 32 into the lower gap 36 and discharged to the side outlet 34. Also, where
Since the screw 26 and the rotary blade 30 are smaller in diameter than the inlet 4 and the passage 45 is formed in an inverted conical shape, only a small amount of water is injected during the crushing, and the water and the garbage are separated by a crushing mechanism 8 below. As a result, water can be saved and efficient crushing can be achieved. Further, the crushing mechanism 8 located below the screw 26 can be submerged by injecting a small amount of water, and the crushing noise can be shielded by water to reduce noise. In addition, soft and long materials such as squid and fibrous materials, which are considered difficult to treat in the prior art, are forcibly guided to the crushing mechanism 8 by the screw 26 and can be crushed quickly. Further, wastewater discharged in the sink during normal cooking flows down in the passage 45 and is transferred to the transfer mechanism 7 and the crushing mechanism 8.
While cleaning the part, through the opening 32A of the fixed blade 32,
The water is discharged from the gap 36 to the discharge port 34.
Through the gap 36. Here, the opening 25B
Is provided with a filter, so that relatively clean water flows into the gap 36 from the communication passage 46, so that the shaft sealing device 40
And the joint 41 are always washed to maintain good water sealing, and the waste is also drained from the opening 19A which is located in the opposite direction to the discharge port 34 with respect to the rotating shaft 6A, so that the kitchen waste is discharged.
It can be discharged smoothly toward.

When the communication passage 46 outside the inner cylinder 44 is filled with water, the surroundings of the transfer mechanism 7 and the crushing mechanism 8 are surrounded by water. Noise can be reduced. The inner cylinder 25 is detachably mounted between the cylinder 10 and the housing 22. By removing the sealing body 15, the inner cylinder 25 is integrated with the transfer mechanism 7 and the crushing mechanism 8. Can be taken out from the inlet 4 of the sink 2 upward. Further, by removing the C-ring 28, the screw 26 and the rotary blade 30 can be removed from the driven shaft 27. Therefore, it is possible to easily take out a foreign substance such as a spoon that has fallen from the input port 4 by mistake and perform cleaning and inspection.
It is not necessary to disassemble the body parts of the kitchen waste treatment device such as the housing 9 and the housing 22, and the work can be performed sanitarily and easily without the kitchen waste and sewage leaking out. Further, by providing an engaging portion 27A such as a groove for engaging a tool such as a screwdriver at the upper end of the screw 26 or the driven shaft 27, the driven shaft 2
The release when the lock 7 is locked by the foreign matter can be performed from above the sink 2 through the insertion port 4.

[0013] Here, as shown in FIG.
When the tube 6 is removed from the slot 4, the inner cylinder 25 is pushed upward by the repulsive force of the pressing spring 18, so that the engagement of the joint 41 is released, and the inner cylinder 25 is held at a position where the upper end contacts the sealing body 15. Is done. Therefore, even if the plug 16 is inadvertently detached during the crushing operation, the rotational power of the electric motor 6 is cut off from the driven shaft 27, and the screw 26 and the rotary blade 30 are immediately stopped. It is possible to improve safety and reliability by preventing the garbage inside from jumping out and crushing noise and odor from leaking out. Further, instead of the pressing spring 18, magnets of the same polarity are opposed to both the inner cylinder 25 and the peripheral part such as the outer cylinder 19 so as to repel each other. By providing magnets of the same polarity to attract each other so that the inner cylinder 25 always receives an upward force, the same function as that of the pressing spring 18 can be performed.

Further, as a development plan of the illustrated example, the sealing body 15
May be integrated with the plug 16, or the plug 16 may be formed of an elastic material such as rubber. Here, in order to prevent the stopper 16 from being accidentally detached, the stopper 16 is connected to the cylindrical body 1.
An engagement structure such as screwing into zero may be used. In this case, since the outer diameter of the inner cylinder 25 is formed slightly smaller than the inner diameter of the cylinder 10, when the stopper 16 is removed, the upper portion of the inner cylinder 25 is repelled by the pressing spring 18. Since it can be made to be exposed above the bottom surface of the sink 2 from the inlet 4, it is easy to take out the inner cylinder 25 during inspection and cleaning, and it is possible to further improve the handleability. Further, if the structure is such that a proximity switch for turning off the power supply or an alarm device such as a buzzer is operated when the inner cylinder 25 moves upward, the safety is further improved. For example, a permanent magnet is provided on the upper edge of the inner cylinder 25, and a proximity switch is provided on the cylindrical body 10 which is close to and opposed to the power supply circuit. Here, if an annular permanent magnet is attached to the upper edge of the inner cylinder 25, for example, in addition to a steel crown lid and a clip of a bottle, tableware made of a magnetic material, etc. can be inserted into the input port 4 during cooking. When it is about to fall, it is attracted and captured by a magnet, and the transfer mechanism 7 and the crushing mechanism 8
Can be prevented from being locked by a foreign object. When the garbage disposal device cannot be operated due to a power failure or the like, the screw 26
Alternatively, by removing the entire inner cylinder 25 and attaching a commercially available bag for collecting garbage or a net basket in the input port 4, the same usage method as that of the drain port of the conventional sink can be quickly performed. it can.
