DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage processing apparatus for heating and drying garbage, resin packs, shells, and other garbage discharged from kitchens such as ordinary households and restaurants.

[0002]

2. Description of the Related Art Conventionally, this type of garbage disposal apparatus stirs garbage stored in a storage tank heated by a heating means by rotating a stirring member assembled to the storage tank by a driving means, thereby heating the garbage. It was to be dried. In this case, when rotating the stirring member, for example,
As disclosed in Japanese Patent Application Laid-Open No. 49977, the operation of continuously rotating the motor or rotating a plurality of times and stopping for a predetermined time is repeated.

[0003]

However, in the above-mentioned conventional apparatus, when the stirring member is continuously rotated, the garbage is excessively stirred, fish and the like become sticky with oil, and grains are removed. There has been a problem that processing may become impossible due to stickiness or the like. On the other hand, when the operation of rotating the stirring member a plurality of times and stopping for a predetermined time is repeated, if the stop time between the rotations is short, the same problem as when the stirring member is continuously rotated occurs. If the stop time between the rotations is long, the kitchen garbage will remain stationary for an unnecessarily long time, and only the surface will dry, reducing the heating and drying efficiency of the entire kitchen garbage. Has been a problem.

Next, the operation of this embodiment configured as described above will be described with reference to the time charts of FIGS.
This will be described with reference to the flowchart of FIG.

A-1. Overview When a power switch (not shown) is turned on, the electric control circuit 70 starts executing the program in step 100 of FIG. 10 and first executes an initial setting process of step 102. This initial setting process is performed in accordance with flags FLG1 to FLG
LG4 and the count values CNT1 and CNT2 are each set to the value “0”, and the value of the time data TD is set to the fifth.
This is a process for setting a predetermined time T5 (for example, 21.4 seconds). Then, the circulation process consisting of steps 104 to 110 is repeatedly executed, and on the condition that the insertion cover 12 is locked and the key switch 71 is on,
It continues to wait for the operation of the start switch 61a or the ejection switch 61c. At this time, in step 106, the second, third and fourth predetermined times T2, T3 and T4 are set to the first and second garbage amount setting switches 61b1 and 61 on the panel 61.
In accordance with the operation of b2, each is set to a value corresponding to the mass of the garbage designated by the operation (for example, the amount of garbage 1
1 hour, 2 hours and 4 hours for 0kg respectively
One and a half hours, 3 hours and 6 hours for 20kg of kitchen waste).

During the circulating process of steps 104 to 110, after the garbage is charged into the tank 11 from the charging port 11a, the charging cover 12 is closed and locked, whereby the key switch is turned on, and the start switch is turned on. When the switch 61a is turned on, the electric control circuit 70 proceeds to step 108.
Is determined to be "YES", and the program proceeds to step 114 and subsequent steps in FIG. Thereafter, the electric control circuit 70 heats and dries the garbage in the tank 11 by executing the processing including steps 114 to 134 (see FIG. 8). After the heating and drying process, steps 136 to 1 in FIG.
By executing the process consisting of 50, the kitchen waste in the tank 11 that has been subjected to the heat-drying process is cooled. Further, after this cooling, if the container 18 is in a state where the kitchen waste can be introduced from the discharge port 11b and the container set switch 19 is in the ON state, the process of FIG. The processing consisting of steps 156 to 174 is executed to discharge the cooled garbage.

If the discharge switch 61c is turned on during the circulation processing in steps 104 to 110, the electric control circuit 70 determines "YES" in step 110, and the container 18 is placed in the container 11 from the discharge port 11b. The program proceeds to step 156 and thereafter on condition that the container set switch 19 is in the ON state and the container set switch 19 is in the ON state.
The discharge of kitchen waste in the tank 11 is started directly without going through the heating and drying process.

A-2. Heat-drying process Next, the heat-drying process will be described in detail. When heating and drying the garbage in the tank 11, the electric control circuit 70 first resets the first timer 72 in step 114 to start time measurement. Step 11
In 6, the drying lamp 61e is turned on. In step 118, the discharge port cover motor 13 is driven until the closed state detection sensor 13f detects the closed state of the discharge port 11b.
e to close the discharge port 11b. In step 120, the hot air fan motor 43 and the exhaust fan motor 52 are operated to start the rotation of the hot air fan 42 and the exhaust fan, to start circulating the inside air of the tank 11, and to remove the inside air to the atmosphere via the deodorizing device 53. Start to release. Then, after each of these processes, step 122
To 134 are repeatedly executed.

In step 122, a tank heater control process is executed. In the tank heater control process, the temperature of the bottom 11c of the tank 11 is reduced to a predetermined lower limit temperature (for example, 1) based on the detection of the tank temperature sensor 15.
When the temperature falls to 27 ° C. or lower, the tank heater 14 is operated, and when the temperature of the bottom portion 11c rises by the operation and reaches a predetermined upper limit temperature (for example, 130 ° C.), the operation is stopped. Thereby, the above steps 122 to 134
During the circulating process, the temperature of the bottom 11c of the tank 11 is maintained between the predetermined upper limit temperature and the lower limit temperature, and the garbage in the tank 11 is heated. However, by setting the upper limit temperature to a high value (for example, 150 ° C.) for a predetermined time (for example, one hour) after the start of the heating and drying process, the temperature of the bottom portion 11c is set to the high upper limit value. Raise to temperature. Thereby, before evaporating the water contained in the garbage, the process of raising the temperature of the garbage itself can be completed in a short time, so that the heating and drying efficiency of the garbage processing apparatus is improved.

In step 124, a hot air heater control process is executed. In this hot air heater control process, when the temperature detected by the hot air temperature sensor 46 falls below a predetermined lower limit temperature (for example, 127 ° C.), the hot air heater 45 is operated, and the detected temperature rises by the same operation. When the temperature reaches a predetermined upper limit temperature (for example, 130 ° C.), the operation is stopped. As a result, step 12
During the circulation process of 2-134, the temperature of the hot air heated by the hot air heater 45 is maintained between the above-mentioned predetermined upper limit temperature and lower limit temperature. Then, the hot air is blown to the kitchen waste in the tank 11 by the hot air fan 42 and circulates to heat the kitchen waste. However, by setting the upper limit temperature to a high value (for example, 150 ° C.) for a predetermined time (for example, one hour) after the start of the heating and drying process, the temperature of the hot air is set to the high upper limit value. Raise to temperature. Thereby, similarly to the tank heater control processing in step 122, the heating and drying efficiency of the kitchen waste treatment apparatus is improved.

At step 126, a catalyst heater control process is executed. In this catalyst heater control process, when the temperature detected by the catalyst temperature sensor 53c falls below a predetermined lower limit temperature (for example, 400 ° C.), the catalyst heater 53b is operated, and the detected temperature rises by the same operation. When the temperature reaches a predetermined upper limit temperature (for example, 600 ° C.), the operation is stopped. Thus, during the circulation processing in steps 122 to 134, the temperature at which the inside air of the tank 11 discharged into the atmosphere passes through the catalyst 53a is maintained between the predetermined upper limit temperature and the lower limit temperature. The deodorizing efficiency of the catalyst 53a is stabilized.

In step 128, a stirring motor control process is executed. This stirring motor control processing is for controlling the operation of the stirring motor 31 to stir the garbage in the tank 11 so that the whole of the garbage is heated and to facilitate the evaporation of the water contained in the garbage. Processing. The details will be described later.

Each control in each of the steps 122 to 128 is executed at any time during the circulation processing in the steps 122 to 134 without stopping the progress of the program.

During the circulation processing in steps 122 to 134, the fourth predetermined time T4 set in step 106 in FIG.
When the first timer 72, which has been reset and started in step 114, counts the predetermined time T4, step 134
Based on the determination of "YES" in the above, the electric control circuit 70 advances the program to step 136 and subsequent steps in FIG. 12, and ends the heating and drying process.

During the circulating process in the steps 122 to 134, when the lock of the input cover 12 is released and the key switch 71 is turned off, or the stop switch 61
If d is turned on, the electric control circuit 70 executes the program in FIG.
Then, the process proceeds to step 152, and the heating and drying process is stopped. In step 152, the tank heater 14, the stirring motor 31, the hot air fan motor 43, the hot air heater 4
5. The operations of the exhaust fan motor 52 and the catalyst heater 53c are all stopped. If the operation has already been stopped, the stopped state is continued. Further, the drying process lamp 61e is turned off. And after each of these processes,
The program proceeds to step 102 and subsequent steps.

A-2-1. Stirring Motor Control Process Next, the stirring motor control process in step 128 will be described in detail. In this stirring motor control process, as shown in FIGS.
Based on the time counted by the first timer 72, which has been reset and started at 14, different stirring processes are executed as time elapses.

When the execution of the stirring motor control process is started in step 200 of FIG. 14, the time of the first timer 72 is set to a first predetermined time T1 (for example, 3).
Min), the “N” in step 202
Based on the determination of "O", the electric control circuit 70 proceeds to step 20.
4 is performed. In this continuous stirring process, the stirrer motor 31 is continuously operated while switching its direction every predetermined time (for example, 30 seconds), and the stirrer member 20 is turned on.
Is continuously rotated to stir the garbage in the tank 11. Thereby, the garbage to be heated and dried is crushed in advance and homogenized in the tank 11 as a whole, so that the heating and drying efficiency of the entire garbage is improved.

On the other hand, if the time counted by the first timer 72 is equal to or longer than the first predetermined time T1 and shorter than the second predetermined time T2 set in step 106 in FIG.
2 and “N” in step 206.
Based on the determination of "O", the electric control circuit 70 proceeds to step 20.
8 is executed. Also, the time counted by the first timer 72 is equal to or longer than the second predetermined time T2 and
If it is shorter than the third predetermined time T4 set in step 6, “YES” in steps 202 and 206 and step 2
Based on the determination of "NO" in step 10, step 212
After the processing of (1) is executed, the divided stirring processing of step 208 is executed. In this divided stirring process, the stirring motor 31 is controlled to cause the stirring member 20 to repeat the operation of rotating by 45 degrees and stopping for the time represented by the time data TD, thereby stirring the garbage in the tank 11. The details and step 212 will be described later.

On the other hand, if the time counted by the first timer 72 is equal to or longer than the third predetermined time T3, steps 202, 206, and 2
Based on the determination of "YES" in step 10, step 21
4 Intermittent stirring is performed. In this intermittent stirring process, the stirring motor 31 is repeatedly operated for a predetermined time (for example, 15 seconds) and stopped for a predetermined time (for example, 5 seconds).
The operation of rotating the stirring member 20 for at least one rotation and stopping for a predetermined time is repeated to stir the garbage in the tank 11. The direction of the rotation is a predetermined number of times (for example, 1
Times). Thereby, when the heat-drying process proceeds and the amount of water contained in the garbage in the tank 11 decreases, while avoiding excessive stirring of the garbage, only the surface is dried and the entire garbage is heated and dried. A decrease in efficiency can be avoided.

The above steps 204, 208, 21
Each control in each process of step 4 is also performed in steps 122 to 1 described above.
Like the control in each process of 28, the progress of the program is not stopped, but is executed at any time when the stirring motor control process is executed during the circulation process in steps 122 to 134. These steps 204, 2
Each time the processing of steps 08 and 214 is completed, the electric control circuit 70 ends the stirring motor control processing in step 216.

A-2-2. Next, the divided stirring process in step 208 will be described in detail. After starting the execution of the divided stirring process in step 300 of FIG. 15, the electric control circuit 70 determines in step 302 whether the count value CNT1 is equal to or greater than a predetermined value N (for example, 4). Is determined, and in step 304, it is determined whether or not the flag FLG1 is a value “1”. The count value CNT1 is for measuring the number of times the rotation direction of the stirring member 20 has been switched. The flag FLG1 indicates that the value of the second timer 73 is “1”.
Is a flag that prohibits the reset start and allows the reset start with a value “0”. First, the count value C
Since the value of NT1 and the flag FLG1 are set to “0” in step 102 of FIG. 10, the electric control circuit 70 determines “NO” in both steps 302 and 304, and advances the program to step 306 and subsequent steps. Step 30
At 6, the second timer 73 is reset and started to start timing. Also, in step 308,
The flag FLG1 is set to the value “1”. Thus, when the divided stirring process is performed next time, the electric control circuit 70 determines “YES” in the above-described step 304, and executes the program in step 310 without resetting the second timer 73 again in step 306. It will proceed to the following.

Steps 310 to 336 correspond to the flag FLG.
This is a process for controlling the operation of the stirring motor 31 based on the value of 2. The flag FLG2 is a flag that is set to a value “1” when the stirring motor 31 is operating and is set to a value “0” when the motor 31 is not operating.

At first, the stirring motor 31 is continuously operated under the control of the continuous stirring process in step 204 in FIG. 14, and the flag FLG2 is set to the value "1". Is "Y" in step 310.
ES ”and the program proceeds to step 312 and subsequent steps. In step 312, the rotational position sensor 36
It is determined whether or not has newly detected the proximity of the protruding portion 35a of the rotating plate 35. If there is no new detection at this time, the divided stirring process is terminated in step 340 based on the determination of “NO”.

Thereafter, each time the divided stirring process is performed,
The electric control circuit 70 repeatedly executes the determination processing of step 312. During the repetitive execution, the stirring motor 31 continues to operate, and the rotary plate 35 continues to rotate together with the stirring member 20. When the rotation position sensor 36 newly detects the approach of the protruding portion 35a of the rotating plate 35, the electric control circuit 70 determines in step 314 that the stirring motor 31 The operation is stopped, the flag FLG2 is set to a value “0” in step 316, and the third flag is set in step 318.
The timer 74 is reset and started to start timing.
Then, after each of these processes, in step 340, the divided stirring process ends.

The flag FLG in the above step 316
When the divided stirring process is executed from the next time onward by the setting of 2, the electric control circuit 70 sets “N” in step 310.
O "is determined, and the program proceeds to step 320 and subsequent steps. In step 320, it is determined whether or not the time counted by the second timer 73 is equal to or longer than a preset sixth predetermined time T6 (for example, three minutes). If the time measured by the timer 73 has not reached the predetermined time T6, "N
O "is determined, and the program proceeds to step 322 and subsequent steps. In step 322, it is determined whether or not the time counted by the third timer 74 is equal to or longer than the time represented by the time data TD. At this time, the time of the timer 74 is equal to the data T
If the time represented by D has not been reached, the divided stirring process is terminated in step 340 based on the determination of “NO”.

During the repetitive execution of steps 320 and 322, the time indicated by the time data TD has elapsed since the operation of the stirring motor 31 was stopped in step 314, and the third reset operation started in step 318. When the timer 74 measures the time represented by the data TD, the electric control circuit 70 advances the program to step 324 and subsequent steps based on the determination of “YES” in step 322.
In steps 324 to 328, the rotation of the stirring member 20 is started by operating the stirring motor 31. However,
At this time, the direction of the rotation is determined based on the value of the flag FLG3. The flag FLG3 is a flag that indicates the operation of the stirring motor 31 in the forward direction (counterclockwise direction in FIG. 4) when the value is “0”, and indicates the operation in the reverse direction when the value is “1”. In step 330, the flag FLG2
Is a value “1” indicating that the stirring motor 31 is operating.
Set to. Thus, the electric control circuit 70 determines “YES” in step 310 and executes the program again in step 3 when the divided stirring process is performed next time.
It will proceed to 12 and later. Then, after each of these processes, in step 342, the divided stirring process ends.

As described above, every time the divided stirring process is executed, the electric control circuit 70 executes the steps 310 to 330.
Is repeatedly executed, and the operation of the stirring motor 31 is stopped every time the rotational position sensor 36 newly detects the proximity of the protruding portion 35a of the rotating plate 35, and the time represented by the time data TD after the stop has elapsed. It is started every time. Therefore, the stirring member 20 rotates by 45 degrees and the time data T
The operation of stopping for the time represented by D is repeated (see FIG. 9).
According to this, while avoiding excessively stirring the garbage in the tank 11, the garbage is prevented from standing still for an unnecessarily long time, and only the surface is dried to heat and dry the entire garbage. It is possible to prevent the efficiency from being lowered and the kitchen waste from burning and sticking to the inner wall of the tank 11.

On the other hand, during the repetitive execution of the divided stirring process,
When the second timer 73 reset and started in step 306 measures the sixth predetermined time T6, the electric control circuit 70 determines “YES” in step 320, and advances the program to step 332 and subsequent steps. Step 332
, The value of the flag FLG3 is inverted. That is, if the flag FLG3 has been a value “0” indicating the operation of the stirring motor 31 in the forward direction, the flag FLG3
Is set to a value "1" representing the operation of the motor 31 in the reverse direction, and if the flag FLG3 has been a value "1" until then, the flag FLG is set to a value "0". As a result, the direction in which the stirring motor 31 is operated when the process including the steps 330 to 334 is executed is switched, and the direction in which the stirring member 20 is rotated next time is switched.
In step 334, the value “1” is added to the count value CNT1. Thus, the number of times that the rotation direction of the stirring motor 31 has been switched by the processing of the step 332 is measured. In step 336, the flag F
LG1 is set to the value “0”. Accordingly, the next time the determination process of step 304 is executed, the electric control circuit 70 determines “NO”, and the second
The timer 73 is reset and started to start timing. Then, after each of these processes, in step 340, the divided stirring process ends.

Thereafter, the second timer 73 is set to the sixth predetermined time T6.
Every time is measured, the operation direction of the stirring motor 31 is switched in step 332 as described above. Therefore,
The agitating member 20 is rotated by the above-mentioned 45 degrees and the time data T
During the repetition of the operation of stopping for the time represented by D, the rotation direction is switched every sixth predetermined time T6 (see FIG. 9).
As a result, the garbage in the tank 11 is more uniformly heated, and the efficiency of the heating and drying treatment of the entire garbage is improved.

On the other hand, during the repeated execution of the divided stirring process,
When the number of times the operation direction of the stirring motor 31 is switched reaches the predetermined value N and the value of the count value CNT1 reaches the predetermined value N, the electric control circuit 70 determines based on the determination of “YES” in the step 302. , A stripping control process of step 338 is executed. The stripping and stirring process is a process of controlling the stirring motor 31 based on the value of the flag FLG2 to rotate the stirring member 20 semi-continuously by one rotation to stir the garbage in the tank 11.

First, since the flag FLG2 is set to the value "0" in step 316 in FIG. 15, the electric control circuit 70 starts executing the stripping and stirring process in step 400 in FIG. , "NO" is determined in step 402, and the program proceeds to step 404 and subsequent steps. In steps 404 to 408, the stirring motor 31 is operated to start the rotation of the stirring member 20.
However, at this time, the direction of the rotation is determined based on the value of the flag FLG4. The flag FLG4 is a flag indicating the operating direction of the stirring motor 31 in the stripping and stirring process. A value “0” indicates the operation of the stirring motor 31 in the forward direction, and a value “1” indicates the operation in the reverse direction. Represents In step 410, the flag FLG2 is set to a value "1" indicating that the stirring motor 31 is operating. In step 412, the count value CNT2 is set to a value “0”. After the start of the operation of the stirring motor 31 in steps 404 to 408, the count value CNT2 is
The number of times the rotation position sensor 36 newly detects the vicinity of the protruding portion 35a of the rotating plate 35 is measured. Then, after each of these processes, the stripping / stirring process ends at step 428, and the split stirring process ends at step 340 in FIG.

The flag FLG in the above step 410
When the stripping and stirring process is performed in the next and subsequent times according to the setting of 2, the electric control circuit 70 executes the program in step 4 based on the determination of “YES” in step 402.
Proceed to 14 or later. In step 414, it is determined whether or not the rotational position sensor 36 newly detects the approach of the protruding portion 35a of the rotating plate 35. If there is no new detection at this time, step 4 is performed based on the determination of “NO”.
At 28, the stripping and stirring process is terminated, and at step 340 in FIG. 15, the split stirring process is terminated.

Thereafter, each time the stripping and stirring process is performed, the electric control circuit 70 repeatedly executes the determination process of step 414. During the repetitive execution, the stirring motor 31 continues to operate, and the rotary plate 35 continues to rotate together with the stirring member 20. When the rotation position sensor 36 newly detects the proximity of the protruding portion 35a of the rotating plate 35,
Based on the determination of “YES” in step 414, the electric control circuit 70 adds the value “1” to the count value CNT2 in step 416, and
At step 8, it is determined whether or not the count value CNT2 added is equal to or greater than the value "12". If the count value CNT2 has not reached the value "12" at this time, "NO"
In step 428, the stripping and stirring process is terminated, and in step 340 in FIG. 15, the split stirring process is terminated.

By repeatedly executing the processing consisting of steps 414 to 418, the stirring member 20 and the rotating plate 35
Each time the rotation position sensor 36 rotates five degrees and the rotation position sensor 36 newly detects the proximity of the protruding portion 35a of the rotating plate 35, the count value CN
T2 is incremented by "1". And the count value CN
When T2 reaches the value “12”, that is, when the stirring member 20 and the rotating plate 35 have rotated one and a half rotations after the operation of the stirring motor 31 has been started in steps 404 to 408, the electric control circuit 70 executes the step “YE” at 418
In step 420, the stirring motor 3
At the same time, the flag FLG2 is set to a value "0" at step 422. Step 4
At 24, the count value CNT1 is set to the value “0”. Thus, when the divided stirring process is performed next time, the electric control circuit 70 determines “NO” in step 302 of FIG.
It will proceed to 04 or later.

In step 426, the value of the flag FLG4 is inverted. That is, if the flag FLG4 is a value “0” indicating the operation of the stirring motor 31 in the forward direction in the stripping and stirring process, the flag FLG4 is set to a value “0” indicating the operation of the motor 31 in the reverse direction. 1 ", and the flag FLG4 has been set to the value" 1 "until then.
If so, the flag FLG4 is set to the value "0".
As a result, when the stripping and stirring process is next performed and the process including steps 404 to 408 is performed, the direction in which the stirring motor 31 is operated and the stirring member 20 is rotated is switched.

Thereafter, every time the switching of the operation direction of the stirring motor 31 in step 332 in FIG. 15 is performed a predetermined value N times, the stripping and stirring process in step 338 is executed as described above, and 20 is rotated one half turn (see FIG. 8). Thereby, the garbage in the tank 11 is more efficiently agitated, so that the garbage is prevented from sticking to the inner wall of the tank 11 more reliably.

As described in the section a-2-1, when the time counted by the first timer 72 is equal to or longer than the second predetermined time T2 and shorter than the third predetermined time T3, the electric control circuit 70 operates as shown in FIG. After performing the process of step 212, the divided stirring process is performed. The process of step 212 is
The value of the time data TD is changed to a seventh predetermined time T7 (for example, 1
(1 second). This seventh predetermined time T7
Is a time shorter than the fifth predetermined time set in the time data TD in step 102 of FIG. Therefore, during the repetition of the operation in which the stirring member 20 rotates by 45 degrees and stops for the time represented by the time data TD, the first
After the timer 72 has counted the second predetermined time T2, the stop time is made shorter than before. Thereby, even if the heating and drying process proceeds and the amount of water contained in the garbage in the tank 11 decreases, the garbage is prevented from being excessively stirred, and only the surface is dried to heat the entire garbage. It is possible to prevent the drying efficiency from being lowered and the kitchen garbage from burning and sticking to the inner wall of the tank 11.

A-3. Cooling Next, the process of cooling the garbage in the tank 11 will be described in detail. When the heating and drying process is completed, the electric control circuit 70 advances the program to step 136 and subsequent steps in FIG. 12, and starts cooling the garbage subjected to the heating and drying process. In step 136, the first timer 72 is reset and started to start timing. In step 138, the operations of the tank heater 14, the hot air heater 45, and the catalyst heater 53c are stopped. And after each of these processes,
The circulation processing consisting of steps 140 to 146 is repeatedly executed.

During the circulation processing in steps 140 to 146, the electric control circuit 70 determines in FIG.
The continuous stirring process similar to step 204 in step 4 is repeatedly executed. Thus, during the circulation processing, the stirring member 20 continuously rotates while switching its direction at predetermined time intervals. On the other hand, at this time, the rotation of the hot air fan 42 and the exhaust fan started in the step 120 of FIG. 11 is continuing, and the inside air in the tank 11 continues to circulate by each of the rotations. Some continue to be released into the atmosphere. Therefore, at this time, the garbage in the tank 11 is gradually cooled while being heated and dried by the residual heat of the tank heater 14 and the hot air heater 45. This allows
At the time of discharging the kitchen waste, which will be described later, a container 18 for storing the kitchen waste.
Problems such as melting of garbage bags in the kitchen due to the heat of the kitchen waste are avoided, and the kitchen waste becomes easier to handle. The hot air fan 4
2 and the rotation of the discharge fan, the surface temperatures of the hot air heater 45 and the catalyst heater 53b are reduced, so that the durability of each of the heaters 45 and 53b is improved.

During the circulation processing in steps 140 to 146, a preset eighth predetermined time T8 (for example, 10 minutes) elapses from the start of the processing for cooling the garbage,
When the first timer 72, which has been reset and started in step 136, counts the predetermined time T8, step 14
6, the electric control circuit 7
In step 146, the operation of the stirring motor 31, the hot air fan motor 43, and the exhaust fan motor 52 is stopped in step 146, the drying process lamp 61e is turned off in step 148, and the process of cooling the garbage ends.

During the circulating process of steps 140 to 146, when the lock of the insertion cover 12 is released and the key switch 71 is turned off, or the stop switch 61
When d is turned on, the electric control circuit 70 advances the program to the above-mentioned step 152 and subsequent steps by the respective judgment processes of steps 142 and 144, and stops the process of cooling the garbage.

A-4. Discharge Next, the process of discharging the garbage in the tank 11 will be described in detail. When the process of cooling the garbage is completed, the electric control circuit 70 advances the program to step 156 and subsequent steps in FIG. 13 to cool the garbage on condition that the container 18 is in a state where the garbage can be introduced from the outlet 11b. Start dumping garbage. In step 156, the first timer 7
2 is reset and started to start timing. In step 158, the discharge lamp 61f is turned on. In step 160, the discharge cover motor 13 is operated until the open state detection sensor 13g detects the open state of the discharge port 11b.
e is operated to open the discharge port lid 11b. In step 162, the stirring motor 31 is operated to start rotating the stirring member 20 in the reverse direction. Then, after each of these processes, the circulation process including steps 164 to 170 is repeatedly executed.

During the circulation processing in steps 164 to 170, the rotation of the stirring member 20 in the reverse direction started in step 162 is continuously continued. This allows
Garbage in the tank 11 is lifted toward the discharge port 11b by the blades 23 of the stirring member 20, and most of the
3 and slides down toward the discharge port 11 b and is discharged out of the tank 11. The discharged garbage is stored in a container 18 through a hopper 16, and the container 18 is tilted (FIG. 4).
Is taken out together with the garbage bag.

During the circulation processing in steps 164 to 170, a preset ninth predetermined time T9 (for example, 4 minutes) has elapsed since the start of the processing for discharging the garbage, and a reset start is performed in step 156. When the first timer 72 counts the predetermined time T9, step 170
Of the electric control circuit 70
Stops the stirring motor 31 in step 172, turns off the discharge lamp 61f in step 174, and ends the process of discharging the kitchen waste in the tank 11. Then, after the end, the program proceeds to step 102 and subsequent steps again.

Also, during the circulation processing of the above-mentioned steps 164 to 170, when the lock of the loading lid 12 is released and the key switch 71 is turned off, the stop switch 61d is turned on, or the container 18 is tilted. When the container set switch 19 is turned off due to the state in which kitchen waste cannot be introduced from the discharge port 11b and the container set switch 19 is turned off, the electric control circuit 70 executes the program in steps 164 to 168 to execute the above-described program in steps 172 to 168. And stop the process of discharging this garbage.

As described above, in the above embodiment,
When the start switch 61a is turned on after putting the garbage into the tank 11, the garbage is heated and dried by selective operation of the motors 31, 43, 52 and the heaters 14, 45, 53b, and is cooled. It is discharged into the rear container 18.
In this case, the opening and closing of the discharge port 11b is automatically switched by the operation of the discharge cover motor 13e, and the process automatically shifts from the heating and drying process to the discharge. In addition, since the heating, drying, cooling, and discharging are not started and continued when the charging port lid 12 is not locked, the motors 31, 43, 52 and the heaters are provided even though the charging port 11a is open. 1
The operation of 4, 45, 53b is avoided, and the usability of the kitchen waste disposal apparatus is improved. In addition, the above discharge
If the container 18 is in a state where the introduction of kitchen waste from the outlet 11b is impossible, the container 1 is not started and continued.
The garbage in 1 is reliably discharged into the container 18, and the usability of the garbage processing apparatus is improved.

B. Second Embodiment Hereinafter, a second embodiment of the present invention in which, when a second predetermined time T2 has elapsed after the start of the heating and drying process, the angle at which the stirring member 20 rotates will be larger than before. Will be described with reference to the drawings. In the second embodiment, a flowchart shown in FIG. 17 instead of FIG. 14 is used as a flowchart showing details of the stirring motor control process in step 128 in FIG. In addition, the divided stirring process in FIG.
Steps 342 to 346 are inserted.

The stirring motor control process of FIG. 17 employs a process of step 218 for setting the value data ND to a value “2” instead of the process of step 212 in FIG. Therefore, in the embodiment, the electric control circuit 70 performs the first
When the time counted by the timer 72 is equal to or longer than the first predetermined time T1 and shorter than the second predetermined time T2, the divided stirring process of step 208 is executed in the same manner as in the first embodiment. If it is not less than T2 and less than the third predetermined time T3, the process of step 218 is executed, and then the divided stirring process of step 208 is executed. The value data ND is used to determine the rotation angle of the stirring member 20, and is initially set to the value "1" in the initial setting process of step 102 in FIG.

In the above-described divided stirring process, the rotation position sensor 36 detects the rotation of the rotating plate 35 while the stirring motor 31 is operating.
When the proximity of the protrusion 35a is newly detected, the electric control circuit 70 adds “1” to the count value CNT3 in step 342 in FIG. 18 based on the determination of “YES” in step 312 in FIG. And count the number of the same detection,
At step 350, it is determined whether or not the count value CNT3 added is equal to or greater than the value represented by the value data ND. It should be noted that this count value CNT3 is determined in step 10 of FIG.
Initially, the value is set to the value “0” in the initial setting process 2. If the count value CNT3 has not reached the data ND at this time, the determination is "NO", and the divided stirring process ends in step 340 of FIG.

By repeatedly executing the processing of steps 312, 342, and 344, the stirring member 20 and the rotating plate 35 are rotated by 45 degrees, and the rotation position sensor 36 is rotated by the rotating plate 3.
Every time the proximity of the five protrusions 35a is newly detected, the count value CNT3 is incremented by "1". Then, when the count value CNT3 reaches the value represented by the value data ND, the electric control circuit 70 determines in step 346 that the count value CNT3 is “YES” in step 344.
Is set to the value "0", the program proceeds to the step 314 and thereafter in FIG. 15, and the operation of the stirring motor 31 is stopped.

As described above, each time the divided stirring process is executed, the electric control circuit 70 executes the above steps 312 and 34.
Steps 310 to 33 including processing consisting of steps 2 to 346
0, 342 to 346 are repeatedly executed, and the operation of the stirring motor 31 is performed by the rotation position sensor 36 by the rotation plate 35.
Is stopped each time the proximity of the protruding portion 35a is detected by the value represented by the value data ND, and is started every time the fifth predetermined time T5 elapses based on the post-stop time data TD.

By the way, as described above, the value data ND is initially set to the value "1" by the initial setting process of step 102 in FIG. At this time, the operation of the stirring motor 31 is stopped every time the rotation position sensor 36 detects the approach of the protruding portion 35a of the rotating plate 35 once, so that the stirring member 20 is rotated by 45 degrees for the fifth predetermined time. The operation of stopping by T5 is repeated. On the other hand, when the second predetermined time has elapsed since the heating and drying processing of the kitchen garbage was started, the first timer 72
After the second predetermined time T2 has been counted, the value data ND
Is set to the value “2” in step 218 of FIG.
At this time, the operation of the stirring motor 31 is controlled by the rotation position sensor 36.
Is stopped each time the proximity of the protruding portion 35a of the rotating plate 35 is detected twice, so that the rotation angle of the stirring member 20 becomes 90 degrees, which is larger than before.

Therefore, according to the present embodiment, as in the first embodiment, even if the heating and drying process proceeds and the amount of water contained in the kitchen waste in the tank 11 decreases, the kitchen waste is excessively stirred. In addition, it is possible to avoid that only the surface is dried and the efficiency of the heating and drying treatment of the entire kitchen garbage is reduced, and that the kitchen garbage is scorched and fixed to the inner wall of the tank 11.

C. Modifications In the first and second embodiments, FIGS.
In the divided stirring process of step 208, the stirring member 2
At 0, the operation of rotating by 45 degrees or 90 degrees and stopping for the time represented by the time data TD is repeated, but the angle of rotating the stirring member 20 is less than 360 degrees, preferably 360 degrees. Any number of values may be used as long as the value is substantially equal to the angle divided by an integer of 3 or more and 12 or less, or a value between 30 and 120 degrees. In this case, it is preferable to provide the protruding portion 35a on the rotating plate 35 for each of the same angle or an angle obtained by dividing the same angle by an integer.

In the first and second embodiments, the rotation amount of the stirring member 20 is monitored based on the detection of the proximity of each protrusion 35a of the rotating plate 35 by the rotation position sensor 36. Instead of providing the rotation position sensor 36 and the rotating plate 35, the rotation amount of the stirring member 20 may be monitored by measuring the operation time of the stirring motor 31. That is, for example, by causing the stirring motor 31 to repeatedly operate for a predetermined time (for example, 1.1 seconds) and stop for a predetermined time, the stirring member 20 can be repeatedly rotated for a predetermined amount and stopped for a predetermined time. You may. Also,
The number of protrusions 35a of the rotating plate 35 may be reduced, and the rotation amount may be monitored by using both the detection of the proximity of each protrusion 35a by the rotation position sensor 36 and the measurement of the operation time of the stirring motor 31. Good.

In the first and second embodiments, the first predetermined time T1 is set in advance, and the second to fourth predetermined times T2 to T4 are set based on the amount of kitchen waste to be heated and dried. When the respective predetermined times T1 to T4 have elapsed from the start of the heating and drying process, the stirring process executed in the stirring motor control process of step 128 in FIG. 11 is switched to switch the operation of the stirring member 20, Although the circulation processing of steps 122 to 134 is ended to end the heating and drying processing, other conditions for each switching or end may be adopted. For example, the weight of the kitchen garbage is measured when the kitchen garbage is put into the tank 11, and the weight of the kitchen garbage being heated and dried is a predetermined ratio (for example, 95%, 60%, 50%, 10
%), The above-described switching or termination may be executed. In addition, during the heating and drying process of the kitchen garbage, the total operation time of the tank heater 14 within the predetermined time is measured every predetermined time (for example, 10 minutes), and the total operation time is a predetermined ratio (for example, , 90% each,
(50%, 40%, 20%), the above-described switching or termination may be executed. Panel 61
, A new switch may be provided to execute the above-described switching or termination when the switch is operated. Further, the temperature of the inside air above the tank 11 introduced into the circulation duct 41 is detected, and when the difference between the detected temperature and the temperature detected by the hot air temperature sensor 46 reaches a predetermined temperature (for example, 25 ° C.), the above-mentioned termination is performed. May be executed.

In the first and second embodiments, when the lock of the loading lid 12 is detected by the key switch 71, the heating and drying of the garbage in the tank 11 and the start and continuation of the cooling and discharging are performed. However, instead of the key switch 71, a switch for detecting the closed state of the insertion port 11b is provided, and the switch 1
The start and continuation may be permitted when the closed state of 1b is detected.

In the first and second embodiments, the discharge opening 11b is automatically opened and closed with the start of the heating and drying process and the discharge of the garbage in the tank 11, but the discharge is performed manually. The discharge opening 11b may be opened and closed by operating the palate 13. In this case, a switch for detecting the open state and the closed state of the outlet 11b is provided, and based on the detection by these switches, the outlet 11b is detected.
The heating and drying process may be permitted when the closed state of the discharge port 11b is detected, and the discharge may be permitted when the open state of the discharge port 11b is detected.
