(Operation of Garbage Disposal Apparatus 1) The garbage disposal apparatus 1 is configured as described above, and processes garbage as described below.

First, the charging lid 26 is opened, and the garbage disposal tank 39 is opened.
Raw garbage and auxiliary materials such as a water conditioning material and a fermentation bacterium are put into the inside of the container, and the input lid 26 is closed.

When the control device 30 detects that the input cover 26 is closed by the cover detecting device 82, the control device 30 operates the stirring device 40 to stir the garbage by the rotation of the stirring claw 60, thereby performing the fermentation / ripening process. I do. At this time, the heater 46 is operated to keep the inside of the garbage disposal tank 39 at an appropriate temperature.

Further, the control device 30 operates the exhaust means 70 and the deodorizing means 71 to supply air (oxygen) to the garbage to promote the fermentation and ripening treatment of the garbage and to generate the garbage from the garbage. The deodorized odor is discharged to the outside of the garbage disposal tank 39.

That is, when the suction fan 72 is driven, air outside the garbage processing tank 39 flows from the intake port 47 to the garbage processing tank 39.
Air (oxygen) is supplied to the garbage by being sucked into 39.

At this time, since a guide plate 48 extending downward from the intake port 47 is attached to a position near the upper portion of the intake port 47, as shown in FIG. The air flows along the guide plate 48 toward the garbage, and then flows from the garbage to the exhaust port 50.

As described above, by the action of the guide plate 48,
Fresh air sucked from the air inlet 47 can be supplied to the garbage, which activates the activity of aerobic bacteria and equalizes the temperature and humidity inside the garbage disposal tank 39. Thus, the fermentation and aging treatment of the garbage can be promoted, and the processing time of the garbage can be shortened.

Since the air supplied to the garbage flows from the garbage toward the exhaust port 50 by the action of the guide plate 48, the air with the odor near the garbage can be reliably removed from the exhaust port.
The garbage can be discharged to the outside from 50, and the generation of offensive odor in the garbage disposal apparatus 1 can be prevented.

Further, since the substantially central portion of the garbage disposal tank 39 is located on the imaginary line 51 connecting the intake port 47 and the exhaust port 50 in a plan view, fresh fresh air sucked from the intake port 47 is provided. Air can be supplied to garbage over a wide area, and air with odor in the vicinity of a wide range of garbage can be discharged to the outside, thereby further reducing the time required for processing garbage. And the generation of offensive odor can be prevented.

When the suction fan 72 is driven, the air inside the garbage processing tank 39 flows from the upper end to the lower end of the exhaust pipe 75, and the air inside the garbage processing tank 39 flows outside the casing 2. Is discharged.

At this time, the pressure inside the exhaust pipe 75 becomes higher than the outside pressure due to the action of the exhaust gas flowing through the inside of the exhaust pipe 75, and a negative pressure is generated in the external air suction hole 78. External air is drawn into the exhaust pipe 75 from the external air suction hole 78.

As described above, by mixing the air with the odor inside the garbage disposal tank 39 flowing inside the exhaust pipe 75 and the air outside the exhaust pipe 75, the odor is diluted by the external air. The odor of the exhaust gas discharged from the exhaust pipe 75 can be reduced.

Moreover, since the air mixing mechanism 77 has a simple structure, it can deodorize odors without using a large-scale device as the deodorizing means 71 described later, so that the deodorizing means 71 can be reduced in size and cost. Therefore, the size and cost of the garbage disposal device 1 can be reduced.

The control device 30 activates the image input means 33 at regular time intervals, detects an image of the upper surface of the garbage by the image input means 33, and operates the stirring means 40 in accordance with the image. To control.

That is, the control device 30 activates the stirring means 40 after the closing lid 26 is closed, and when the color of the processed material in the garbage processing tank 39 becomes close to black by the image input means 33. Judges that it is in a good fermentation state,
When the lamp provided on the operation panel 29 indicating that the garbage can be added can be turned on, and the color of the processed material in the garbage processing tank 39 approximates to reddish brown by the image input means 33. Is determined to be in a good dry state, and a lamp provided on the operation panel 29 for indicating that the final residue can be discharged is turned on.

The image obtained by the image input means 33 is subjected to image processing such as a clustering operation to determine whether or not the processed product is fixed or has become a cluster-like lump due to excessive moisture, and the amount of sub-materials. Can be recognized, and accordingly, by extending the stirring time by the stirring means 40, the treated product can be fermented and matured satisfactorily.

As described above, the provision of the image input means 33 makes it possible to recognize the state of the processed material inside the garbage processing tank 39 and to perform control in accordance with the state. The aging treatment can be performed well.

Further, by operating the image input means 33 only when the closing lid detecting means 82 detects that the closing lid 26 is closed, it is possible to reduce the electric power required for operating the image input means 33. And the running cost of the garbage disposal apparatus 1 can be reduced.

Further, by operating the image input means 33 at regular intervals, the power required for operating the image input means 33 can be further reduced, and the running cost of the garbage disposal apparatus 1 can be reduced. be able to.
