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, whereby 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 FIGS. 8 and 9).

(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.

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).

[0052]

[Table 1]

(Over-moisture condition) 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 condition (a condition in which the processed material contains water of a predetermined value or more). In this case, the set temperature of the heater 46 is set to 50 degrees, which is higher than a normal temperature (40 degrees) described later, and the stirring means 40 is controlled to set the stirring claw shaft 54 to 8
After 10 seconds of forward and reverse rotation, reverse for 0 seconds, stop for 5 seconds, rotate forward for 6 seconds, then stop for 8 minutes and 29 seconds
The reversing operation is repeatedly performed (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.

(Appropriate state) The control device 30 is
If it is detected by 85 that the inside of the garbage processing tank 39 is in an appropriate state (a state in which the amount of water contained in the processed object is within a predetermined range), the state of the processed object is changed from the excessive moisture state to an appropriate state. , And a different stirring pattern is executed when the state of the processed material changes from the dry state to the proper state.

That is, when the state of the processed material changes from the excessive moisture state to the proper state, the control device 30
Is set to 40 degrees, and the stirring means 40 is controlled to rotate the stirring claw shaft 54 in reverse for 4 minutes, then stop for 5 seconds, rotate forward for 6 seconds, and then stop for 25 minutes and 49 seconds. The normal / reverse rotation operation for 30 minutes is repeatedly performed (pattern 2a), and the reverse rotation time of the stirring claw shaft 54 is extended to evaporate the moisture of the processed material in a short time. At that time, the control device 30 operates the suction fan 72 of the exhaust means 70 at a normal air volume.

On the other hand, when the state of the processed material changes from the dry state to the proper state, the control device 30 sets the temperature of the heater 46 to 40 degrees and controls the stirring means 40 to control the stirring claw shaft. 54 was reversed for 2 minutes, then stopped for 5 seconds, 6
After 30 seconds of forward and reverse rotation of 27 minutes and 49 seconds, the normal and reverse rotations are repeated for 30 minutes (pattern 2b), and the reverse rotation time of the stirring claw shaft 54 is shorter than that of the above-described pattern 2a. Water retention is easy.
At that time, the control device 30 operates the suction fan 72 of the exhaust means 70 at a normal air volume.

(Dry state) The control device 30 is
If it is detected by 85 that the inside of the garbage processing 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), the set temperature of the heater 46 is set to 40 degrees. The stirrer 40 is controlled by controlling the stirrer
After a reverse rotation for 2 seconds, the motor is stopped for 5 seconds, then rotated for 6 seconds, and then stopped for 1 hour, 59 minutes and 19 seconds, and a 2-hour forward / reverse rotation operation 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.

The above-described control in the proper state, the dry state, and the over-water state is performed when the control device 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.

In this embodiment, as shown in FIGS. 8 and 10, when the moisture content of the processed product detected by the moisture sensor 85 is 45% or more, the control device 30 When the water content of the processed material becomes 45% or less, the stirring pattern in the excessive moisture state (pattern 1) is changed to the stirring pattern in the appropriate state (pattern 2a). When the pattern is changed and the water content of the processed product is reduced to 35% or less, the stirring pattern is changed from a proper stirring pattern (pattern 2a) to a dry stirring pattern (pattern 3). The pattern is changed (the stirring pattern is not directly changed from the stirring pattern in the excessive moisture state to the stirring pattern in the dry state).

On the other hand, as shown in FIGS. 9 and 10, when the moisture content of the processed product detected by the moisture sensor 85 is 40% or less, the control device 30 sets the dry stirring pattern (pattern 3). When the water content of the processed product becomes 40% or more, the stirring pattern is changed from the dry stirring pattern (pattern 3) to the proper stirring pattern (pattern 2b). When the water content increases and the water content becomes 50% or more, the stirring pattern is changed from the stirring pattern in an appropriate state (pattern 2b) to the stirring pattern in an excess water state (pattern 1). (The stirring pattern is not directly changed from the stirring pattern in the dry state to the stirring pattern in the excessive moisture state).

As described above, in the present embodiment, the state of the processed material is divided into the over-hydrated state, the proper state, and the dry state according to the moisture content, and the state of the processed material is changed from the over-water state to the proper state. The agitation pattern (pattern 2a) to be executed is different from the agitation pattern (pattern 2b) to be executed when the state of the processed material changes from a dry state to an appropriate state, so that the water content of the processed material is Appropriate stirring can be performed, and the fermentation and aging treatment of the processed product can be performed smoothly.

In particular, in this embodiment, when the state of the processed object changes from the over-moisture state to the proper state, the water content of the processed object changes as compared with the case where the state of the processed object changes from the dry state to the proper state. When the state of the processed material changes from the excessive moisture state to the appropriate state by executing the stirring pattern for diverging the water, the water of the processed material can be diverged in a short time, while the state of the processed material is When the state changes from the dry state to the appropriate state, the water retention of the processed material can be performed in a short time, and the fermentation and aging treatment of the processed material can be performed in a short time and smoothly.

Further, in this embodiment, the stirring pattern of the processing object by the stirring means is changed between a case where the water content of the processing object is higher and a case where the water content of the processing object is lower than the threshold value, with a preset water content as a threshold value. And a threshold (40% or 5%) when the water content of the treated material changes in an increasing direction.
0%) and a threshold value (45% or 35%) when the water content of the processed material changes in a decreasing direction, so that the switching of the stirring pattern has hysteresis.

This eliminates the need to frequently change the stirring pattern in accordance with the increase or decrease of the water content even when the water content of the processed product is near the preset threshold value, thereby simplifying the control. Thereby, malfunction of the garbage processing apparatus 1 can be prevented.

In addition, since the stirring pattern does not change frequently, a good fermentation state of the processed product can be maintained, and the fermentation / ripening treatment of the processed product can be performed smoothly.

In this embodiment, the state of the treated product is divided into an over-water state, an appropriate state, and a dry state according to the water content.
Set a stirring pattern according to each state, if the water content of the treated material changes in a direction to decrease, from the stirring pattern in the excess water state to the appropriate stirring pattern, or from the appropriate stirring pattern Change the stirring pattern in the dry state in order in a stepwise manner.On the other hand, when the water content of the processed material changes in the direction of increasing, the stirring pattern in the dry state changes to the proper stirring pattern, or the stirring in the proper state. The control is performed so as to change the pattern from the pattern to the stirring pattern in the over-moisture state in order in a stepwise manner.

With this, the environment to which the processed material is exposed is gradually changed, so that a good fermentation state of the processed material can be maintained and the fermentation / ripening treatment of the processed material can be performed smoothly. .

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 stirring 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 moisture sensor 85 detects that the moisture content of the processed material is 55% or more, the control device 30 turns on a warning lamp for inhibiting the fresh garbage from being added. When the moisture sensor 85 detects that the moisture content of the processed product is 25% or less, a warning lamp indicating that the processed product is in a dry state is turned on. When the water content is 25% or more and 55% or less), a lamp indicating that the state of the processed object is in an appropriate state is turned on.

As described above, in the control of the stirring claw shaft 54, the processing device 30 determines that the water content of the processed material is in the proper state in the range of 35% to 50%, whereas the control of turning on the warning lamp is performed. In the above, when the water content of the treated material is in the range of 25% to 55%, it is determined that the treated product is in an appropriate state.
The switching of the stirring pattern by 54 and the switching of the warning lamp are made different so that the warning lamp is not frequently turned on, thereby simplifying the control of the warning lamp and giving the user a sense of security.

(Overflow Control) When the lid opening / closing detecting means 82 detects that the loading 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 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 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 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 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.

[0083]

The present invention is embodied in the form described above and has the following effects.

That is, according to the present invention, the state of the processed material is divided into a super-hydrated state, a proper state, and a dry state according to the water content, and the processing is executed when the processed state changes from the super-moisture state to the proper state. Since the stirring pattern and the stirring pattern to be executed when the state of the processed material changes from the dry state to the proper state are different, it is possible to perform appropriate stirring appropriate for the water content of the processed material, Fermentation and aging treatment can be performed smoothly.

In particular, when the state of the processed material changes from the over-moisture state to the proper state, the stirring pattern for dispersing the water content of the processed material is compared with the case where the state of the processed material changes from the dry state to the proper state. When the state of the processed material changes from the over-moisture state to the proper state, the moisture of the processed material can be diverged in a short time, while the state of the processed material changes from the dry state to the proper state. If it changes to
Water retention of the processed material can be performed in a short time, and fermentation and aging treatment of the processed material can be performed smoothly in a short time.
