[0033]
In the present embodiment, the processing chamber 8 and the case 4 configured as described above are provided integrally.
[0034]
Here, a rotation sensor 56 is provided at the lower end of the transport motor 53. For example, a photo sensor is used as the rotation sensor 56, and the rotation speed of a fan (not shown) connected to the rotation shaft of the conveyance motor 53 is detected to indirectly determine the conveyance speed of the crushed garbage by the conveyance screw 5. Configured to detect.
[0035]
Next, the garbage processing by the garbage processing apparatus configured as described above will be described.
[0036]
Garbage from the home or the like is put together with water into the inlet 11 of the sink 1 of the kitchen. Garbage thrown into the inlet 11 is pulverized by the disposer 2 and then introduced into the dewatering screen 3 from the inlet 31 of the dewatering screen 3 through the communication path 22 together with the water, and in conjunction with the operation of the disposer 2. By the forward rotation of the conveying screw 5 that operates, the conveying screw 5 is conveyed upward along the upper surface of the screw portion 52 of the conveying screw 5.
[0037]
The ground garbage is transported from the upper end of the dewatering screen 3 to the discharge port 33 by separating the water from the dewatering holes 32 to the outside of the dewatering screen 3 by transporting the screw portion 52.
[0038]
On the other hand, the water discharged from the dewatering hole 32 to the outside of the dewatering screen 3 is drained from the drainage port 41 to the outside of the case 4 through the drainage pipe 42.
[0039]
In this way, when separating the crushed garbage and water in the dewatering screen 3, the crushed garbage is caught between the tip of the screw portion 52 of the conveying screw 5 and the inner wall of the dewatering screen 3. In the case where the transport speed of the crushed garbage by 5 is lower than a preset value, the rotation sensor 56 detects it indirectly by detecting a decrease in the rotational speed of the rotation shaft of the transport motor 53.
[0040]
Thereby, in the control device (not shown), the conveying screw 5 is reversely rotated on the basis of the detection result of the rotation sensor 56, and when it is reversely rotated by a predetermined rotation (for example, 3 rotations), it is rotated forward again. When the rotation sensor 56 detects a decrease in the rotational speed of the rotation shaft of the conveyance motor 53 again when the rotation is made forward, the conveyance screw 5 is reversely rotated in the same manner as described above. That is, the forward rotation operation and the reverse rotation operation are repeatedly performed until the rotation shaft of the conveyance motor 53 rotates forward at a predetermined rotation speed or higher.
[0041]
By controlling the driving of the conveying screw 5 in this way, the conveying screw 5 is reversely connected to release the biting only when the crushed garbage is actually biting into the screw portion 52 and the inner wall of the dewatering screen 3. Rotation is performed, whereby the crushed garbage can be transported upward and dehydrated more efficiently.
[0042]
In the vicinity of the discharge port 33, the tip 72 of the scraping member 7 is brought into sliding contact with the peripheral surface of the cam member 55 as the conveying screw 5 rotates, so that the scraping member 7 is repeatedly swung in the horizontal direction. The scraping member 7 forcibly scrapes the crushed garbage to the outside of the discharge port 33 by the movement of the conveying screw 5 from the shaft core side toward the discharge port 33. In this way, the scraping member 7 scrapes the crushed garbage, so that the crushed garbage can be smoothly discharged to the outside of the discharge port 33.
[0043]
The dehydrated crushed garbage discharged from the discharge port 33 through the chute 81 to the processing chamber 8 is suitably stirred with the decomposition chip by the stirring member 83 in the processing tank 82, and rapidly fermented by heating by the heater 86. And disassembled.
[0044]
In this decomposition process, odor and moisture generated in the processing chamber 8 are introduced into the space 43 in the case 4 from the exhaust port 87 through the exhaust pipe 88 by the exhaust fan 89 and drained from the drain port 41 through the drain pipe 42. And it is exhausted to the outside.
[0045]
As a result of the above-described decomposition processing of the crushed garbage in the processing chamber 8, the processed product is gradually stored in the processing tank 82, and when this processed product becomes full in the processing tank 82, the full sensor detects this. To do. If there is this detection, the operation is stopped, the processed material in the processing tank 82 is taken out of the processing chamber 8 through an opening / closing door (not shown), and after a predetermined amount of disassembly chip is put into the processing tank 82, it continues. The crushed garbage is decomposed as described above.
[0046]
Thus, when the disposer 2 is operated and the crushed garbage is introduced into the dewatering screen 3 together with water, the crushed garbage is suitably treated as described above. On the other hand, there is a case where the disposer 2 is inadvertently forgotten to operate even when garbage is thrown into the inlet 11. For example, tea leaves or the like may be left as it is. In such a case, small fine garbage originally introduced without being pulverized is introduced into the dewatering screen 3 through the disposer 2 together with the inflow of water.
[0047]
At this time, the water level temporarily rises in the dehydration screen 3 due to the inflow of water, and the water level sensor 6 detects this rise in water level. As a result, the transport motor 53 rotates the transport screw 5 in a forward direction for a predetermined time, and fine garbage introduced around the inlet 31 of the dewatering screen 3 is transported upward in the dewatering screen 3 and is discharged from the discharge port 33 to the processing chamber. Eject to 8. That is, the operation of the conveying screw 5 in this case is set to a time that allows fine garbage to be discharged by the conveying screw 5.
[0048]
In this way, regardless of the operation of the disposer 2, by operating the conveying screw 5 for a predetermined time by detecting the rise of the water level, it is possible to prevent fine garbage from staying around the inlet 31 of the dewatering screen 3, It is possible to prevent such garbage from adhering and blocking due to adhesion, and to prevent the generation of odor.
[0049]
For example, when tea leaves or the like adhere to the dehydration screen 3, the dehydration holes 32 are closed. Therefore, when a large amount of water flows into the dehydration screen 3 in this state, the dehydration screen 3 is lifted and discharged from the discharge port 33. Although it may leak out to the 8th side, since the blockage by the adhesion of garbage can be prevented by the operation of the conveying screw 5 described above, such a problem can be solved, and thereby smooth garbage disposal can be performed. Can do.
[0050]
Further, since the detection part 61 of the water level sensor 6 is in sliding contact with the tip of the screw part 52 of the conveying screw 5, the surface of the detecting part 61 is constantly cleaned by the operation of the conveying screw 5. As a result, it is possible to prevent a decrease in sensitivity due to adhesion of the deposit on the detection unit 61, and it is possible to prevent malfunction due to a decrease in sensitivity and to operate smoothly.
[0051]
And the garbage processing apparatus comprised in this way is provided with the alerting | reporting means which alert | reports this, when the water level sensor 6 does not operate for a predetermined time. As a notification means, you may make it operate a buzzer, a lamp, etc., and what is necessary is just to set suitably according to living conditions, such as notifying through a communication means. Further, the time during which the water level sensor 6 that is notified by the notification means does not operate may be set as needed according to the living situation. When the time when the water level sensor 6 does not operate in advance is known due to travel or the like, the operation of the notification means is stopped. Just keep it. Therefore, by providing the notification means in this way, it is possible to grasp the living reaction of the elderly living alone.
[0052]
【The invention's effect】
As described above, according to the garbage processing apparatus of the present invention, the conveying screw is operated for a predetermined time based on the detection by the water level sensor, so that the dewatering screen is disposed around the inlet of the dewatering screen regardless of the operation of the disposer. Can prevent the accumulation of small garbage. For this reason, it is possible to prevent such garbage from adhering and blockage due to adhesion, and also to prevent the generation of odor, thereby enabling smooth garbage disposal.
[0053]
In addition, since the detection part of the water level sensor is in sliding contact with the tip of the screw part of the conveying screw, the surface of the detection part is constantly cleaned by this sliding contact, so that the sensitivity of the detection part can be maintained well. Therefore, it is possible to operate smoothly by preventing malfunction due to a decrease in sensitivity.
