Since the guide plate 48 is attached to the intake port 47, the air sucked from the intake port 47 flows toward the garbage along the guide plate 48 as shown in FIG. As a result, fresh air sucked from the intake port 47 can be supplied to the garbage, whereby the activity of aerobic bacteria is activated and the temperature and humidity inside the garbage processing tank 39 are reduced.

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 a suction pipe 73 of a suction fan 72 at an exhaust port 50, an upper end of an exhaust pipe 75 is connected to a discharge pipe 74 of the suction fan 72, and a 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.

The air mixing mechanism 77, as shown in FIG.
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 treatment 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) After the power is turned on,
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.

The control device 30 appropriately performs the following control in accordance with the external temperature detected by the external temperature detection sensor and the water content inside the garbage disposal tank 39 detected by the moisture sensor 85 (see Table 1 and FIG. 9). ).

[0061]

[Table 1]

(Appropriate state) The control device 30 is
When it is detected that the inside of the garbage disposal tank 39 is in an appropriate state (a state in which the amount of water contained in the processed material is within a predetermined range) by 85 (for example, when the water content is 35% or more and 45% or less) ), The set temperature of the heater 46 is set to 40 degrees, and the stirring means 40 is controlled to rotate the stirring claw shaft 54 for 4 minutes, then stop for 5 seconds, and then rotate for 6 seconds, 2
The normal / reverse rotation operation for 30 minutes such as stopping for 5 minutes and 49 seconds is repeatedly performed (pattern 2). At that time, the control device 30 operates the suction fan 72 of the exhaust means 70 at a normal air volume.

(Drying state) The control device 30 is
When it is detected that the inside of the garbage treatment tank 39 is in a dry state (a state in which the amount of water contained in the processed material is equal to or less than a predetermined value) by 85 (for example, when the water content is 35% or less)
After setting the temperature of the heater 46 to 40 degrees and controlling the agitating means 40, the agitating claw shaft 54 is rotated in the reverse direction for 30 seconds, then stopped for 5 seconds, and rotated forward for 6 seconds. Time 59
A 2-hour forward / reverse rotation operation such as stopping for 19 minutes is repeatedly performed (pattern 3). At that time, the control device 30 operates the suction fan 72 of the exhaust means 70 with a smaller airflow than a normal airflow.

(Over-moisture state) The control device 30 has detected by the moisture sensor 85 that the inside of the garbage disposal tank 39 is in an over-moisture state (a state in which the processed material contains water of a predetermined value or more). In this case (for example, when the water content is 45% or more), the set temperature of the heater 46 is set to a normal temperature (40 degrees).
Set the temperature to 50 degrees higher than the
After controlling 40, the stirring claw shaft 54 is reversed for 80 seconds,
A 10-minute forward / reverse operation, such as stopping for 5 seconds, rotating forward for 6 seconds, and stopping for 8 minutes and 29 seconds, is repeated (pattern 1). At that time, the control device 30 operates the suction fan 72 of the exhaust means 70 at a normal air volume.

As described above, in this embodiment, the moisture sensor
If it is detected by 85 that the inside of the garbage disposal tank 39 is in an over-moisture state, the temperature of the heater 46 is controlled to be higher than the normal temperature.

This is because, even when a large amount of water is contained in the processing object, it takes a long time to diffuse the water content of the processing object to an appropriate amount if the heater 46 is set to a normal temperature. However, as in the present embodiment, by setting the temperature of the heater 46 higher than the normal temperature, when a large amount of moisture is contained in the processed material, the moisture is diverged in a short time, This is because the fermentation and aging treatment of the processed material is performed in a short time.

The above-described control in the proper state, the dry state, and the over-moisture state is performed when the controller 30 detects that the temperature outside the garbage processing tank 39 is 25 ° C. or more by the external temperature detection sensor. Only while the temperature outside the garbage disposal tank is 2
If it is detected that the angle is less than 5 degrees, the controller 30
Sets the temperature of the heater 46 to 60 degrees, which is higher than the normal temperature (40 degrees), irrespective of the moisture state inside the garbage processing tank 39 detected by the moisture sensor 85.

This is because even when the external temperature is low,
When 46 is set to the normal temperature, it takes a long time to evaporate the moisture of the processing object to an appropriate amount, but as in this embodiment, the external temperature detected by the external temperature detection sensor is set in advance. If the temperature is lower than the temperature, the temperature of the heater is set higher than the normal temperature regardless of the moisture state inside the garbage processing tank, This is because the moisture is diverged in a short time, and the fermentation and aging treatment of the processed product is performed in a short time.

When 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 controls the agitating claw shaft. The rotation of 54 is temporarily stopped, and thereafter, when the lid opening / closing detecting means 82 detects that the charging lid 26 has changed from the `` open state '' to the `` closed state, '' the control device 30 After the control, the stirring claw shaft 54 is stopped for 5 seconds, then reversely rotated for 1 minute, stopped for 5 seconds, normally rotated for 6 seconds, stopped for 5 seconds, and then operated before the opening lid 26 is opened and closed. Let them repeat 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 and aging of the newly introduced garbage can be performed at an early stage, and the time required for the fermentation and aging treatment can be shortened.

When the cover opening / closing detecting means 82 detects that the closing cover 26 has changed from the “closed state” to the “opened state” during the rotation of the stirring pawl shaft 54, the control device 30 turns on the power supply relay. The operation of the power relay is checked to see if it is operating properly. 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 closing lid 26 has been opened and closed after a predetermined period of time, for example, 30 days after the power is turned on, that is, when the closing 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 forward rotation time of the stirring claw shaft 54 longer than the reverse rotation time, the final residue inside the garbage disposal tank 39 is recovered from the discharge port 49 through the recovery gutter 63 and recovered. 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 charging lid 26 provided in the garbage processing unit 3 has not been opened and closed continuously 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 sub-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 overflow control is executed only after a predetermined time has elapsed after the overflow control has been executed. Therefore, only the fermentation / ripening treatment performed at least for the predetermined time can be performed. It is possible to transfer the garbage that has not been sufficiently fermented to the collection unit 4, and it is possible to reliably prevent a problem that the garbage that is not sufficiently fermented is transferred from the garbage processing unit 3 to the collection unit 4.

According to the second aspect of the present invention, a predetermined number of voltage values or current values that are sequentially larger from the maximum value of the detected voltage values or current values are rejected, and the next larger voltage value or current value is adopted. The temperature of the workpiece to be heated by the heater is controlled by using a predetermined number of voltage or current values that are larger in order from the beginning, and using the average value of the adopted voltage values or current values as the detection result as the final criterion for determining the water content. It is configured to

As described above, some of the detected voltage values or current values from the maximum value may be abnormal values.
Since the voltage value or the current value which has a risk of such an abnormal value is not adopted, it is possible to avoid the heating temperature control of the processing object by the heater based on the abnormal value, and it is possible to perform more appropriate heating temperature control. And as a result,
The aging treatment can be performed reliably and efficiently.
