When the shutter 67 is pulled forward, the garbage disposal tank 39 and the collection tray 62 communicate with each other, and the final residue after the fermentation and aging treatment in the garbage disposal tank 39 is collected at once. It is to be discharged to 62.

As shown in FIGS. 1 to 4, the deodorizing section 5 has an exhaust means 70 for discharging the air inside the garbage disposal tank 39 to the outside, and a deodorizing means for deodorizing the odor generated from the garbage. And deodorizing means 71.

The exhaust means 70 is connected to the exhaust port 50 with the suction pipe 73 of the suction fan 72, the exhaust pipe 74 of the suction fan 72 is connected to the upper end of the exhaust pipe 75, and the lower end of the exhaust pipe 75. The portion is communicated and connected to an exhaust port 76 formed in the base 6.

The exhaust means 70 is provided with an air mixing mechanism 77 for mixing the air inside the garbage disposal tank 39 and the outside air.

As shown in FIG. 3, the air mixing mechanism 77 determines the inner diameter of the upper end of the exhaust pipe 75 by
Expanding from the outer diameter of the lower end of 74, between the discharge pipe 74 and the exhaust pipe 75, forming an external air suction hole 78 for sucking air outside the garbage disposal tank 39, By reducing the diameter of the upper end of the exhaust pipe 75 from the upstream side to the downstream side, a guide wall 79 inclined from the upstream side to the downstream side is formed at the upper end of the exhaust pipe 75.

At this time, due to the action of the exhaust gas flowing inside the exhaust pipe 75, the pressure inside the exhaust pipe 75 becomes higher than the external pressure, 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.

The garbage processing apparatus 1 is configured as described above, and processes garbage as described below (see FIG. 8).

(Initial state) When the power supply 85 is turned on, the power supply LED provided on the operation panel 29 is turned on, and the control device 30 starts measuring elapsed time.

(Fermentation / Aging Control)
When the lid opening / closing detecting means 82 detects that the
That is, when it is detected that the charging lid 26 has been changed from the “closed state” to the “open state” and the “closed state” again, it is determined that the fresh garbage has been newly inserted into the garbage processing tank 39. The controller 30 performs the fermentation / ripening control.

That is, the control device 30 controls the stirring means 40 to rotate the stirring claw shaft 54 in reverse for 4 minutes, then stop for 5 seconds, forward for 6 seconds, and then stop for 25 minutes and 49 seconds. The 30-minute forward / reverse operation is repeated.

If the lid opening / closing detecting means 82 detects that the charging lid 26 has been changed from the "closed state" to the "opened state" during the fermentation / ripening control, the control device 30 When the rotation is temporarily stopped, and thereafter, the lid opening / closing detecting means 82 detects that the charging lid 26 has been changed from the `` open state '' to the `` closed state '', the control device 30 controls the stirring means 40. And the stirring claw shaft 54
Is stopped for 5 seconds, then reversed for 1 minute, stopped for 5 seconds, rotated forward for 6 seconds, stopped for 5 seconds, and then the operation before the opening and closing of the charging lid 26 is repeated again.

In this way, when the charging lid 26 is opened and closed during the fermentation / ripening control, it is determined that new garbage has been added, and the inside of the garbage processing tank 39 is stirred. Thereby, the fermentation / ripening of the freshly introduced garbage is performed at an early stage, and the time required for the fermentation / ripening treatment is shortened.

When the lid opening / closing detecting means 82 detects that the closing lid 26 has changed from the "closed state" to the "opened state" while the stirring claw shaft 54 is rotating, the control device 30 turns on the power supply relay. The operation of the power relay is checked to see if it is operating normally. If a power relay malfunction is detected, the power LED is turned on and a warning is issued. In this case, only a warning is issued, and other controls are performed as usual.

(Overflow Control) When the lid opening / closing detecting means 82 detects that the loading lid 26 has been opened / closed for a predetermined period of time, for example, 30 days after the power is turned on, that is, the loading lid 26 is changed from the “closed state”. Opened and closed again
When the control device 30 detects that has elapsed, the control device 30 starts measuring elapsed time.

Then, the charging lid 26 is kept for a predetermined time, for example, 10 minutes.
If it is not opened and closed continuously for a long time,
Overflow control is performed to transfer the final residue inside 39 to the collection tray 62.

That is, the control device 30 controls the stirring means 40 to rotate the stirring claw shaft 54 forward for 2 minutes, then stop for 5 seconds, reverse for 6 seconds, and then stop for 7 minutes and 49 seconds. Perform forward / reverse operation for 10 minutes.

As described above, by making the normal rotation time of the stirring claw shaft 54 longer than the reverse rotation time, the final residue inside the garbage disposal tank 39 is collected from the discharge port 49 through the collection gutter 63 and collected. It is transferred to the tray 62.

However, when the overflow control is performed once, the control device 30 starts measuring the elapsed time again.
Unless a predetermined time, for example, 10 hours, has elapsed after the previous overflow control, the overflow control is not performed again.

As described above, in the present embodiment, the overflow control is executed only when the input lid 26 provided in the garbage disposal unit 3 has not been continuously opened and closed for a predetermined time. Fermentation for at least a predetermined time
Only the aged product can be transferred to the collection unit 4, and it is possible to reliably prevent the problem that even the garbage that is not sufficiently fermented is transferred from the garbage processing unit 3 to the collection unit 4. it can.

In addition, within a predetermined period after the power is turned on, a large amount of auxiliary materials such as aerobic bacteria and a water regulator for promoting fermentation and ripening are contained in the processed material. If overflow control is performed within a predetermined period, even secondary materials contained in a large amount in the processed material may be transferred to the recovery unit 4 and the subsequent fermentation / ripening process may not be performed smoothly. Since the overflow control is executed only after a predetermined period has elapsed since the power was turned on, it is ensured that even the secondary materials contained in the processed material in large quantities are transferred from the garbage processing section to the collection section. The fermentation and aging treatment can be performed smoothly.

In this embodiment, the execution of the next overflow control is prohibited within a predetermined time after the execution of the overflow control. Therefore, the fermentation / ripening process is performed at least for a predetermined time. It is possible to transfer only the waste to the collection unit 4, and it is possible to reliably prevent a problem that even the garbage that is not sufficiently fermented is transferred from the garbage disposal unit 3 to the collection unit 4.
