The energization is resumed, and the volume of waste is reduced by heating and drying, and the temperature sensor 60 detects the temperature of the outer fixed container 51 containing the basket storage container 41, and the temperature reaches a predetermined temperature. In such a case, it is determined that the heating and drying of the waste has been completed, and the operation is stopped.

  Moreover, as another soot processing machine, there exists a thing shown in Unexamined-Japanese-Patent No. 9-323026 (refer patent document 4). This device has a catalyst deodorizer 56 that deodorizes the odor gas emitted from the soot storage container 41, and is a temperature detector that controls the temperature of the catalyst 56b downstream of the odor gas passing through the catalyst deodorizer 56.

Japanese Patent Laid-Open No. 10-2667 JP 7-294136 A JP-A-9-323026

  However, in the above-described conventional soot disposing machine, the temperature in the catalyst deodorizer 56 is often unstable because various kinds of garbage are thrown in. In some cases, from the rapid temperature rise in the catalyst deodorizer 56, When these are detected and the sensor 56c is operated, there is a drawback that energization is stopped and processing cannot be completed. Further, since the sensor 56c does not automatically return once operated, it cannot be re-energized, and there is a drawback that the sensor 56c needs to be replaced.

  Moreover, in what is shown to patent document 4, the temperature sensor (not shown) which detects the temperature of the catalyst deodorizer 56 is installed in the position away from the exit of the discharge pipe of the catalyst deodorizer 56, and from the outlet Since the temperature of the exhausted gas is detected to control the catalyst temperature, it is easily affected by the surroundings and is difficult to be stably controlled. In addition, the temperature of the catalyst deodorizer 56 is not directly detected, but the catalyst deodorizer. Since the temperature of the gas that has passed through 56 is detected, when the temperature of the catalyst 56b suddenly rises, the temperature detection by the temperature sensor is inevitably delayed, resulting in insufficient protection of the catalyst 56b and an abnormal temperature. There is a drawback that the sensor 56c to be detected operates.

  Reference numeral 23 denotes an overheat prevention device, which is provided on the outer surface of the hot air circulation case 12 with the hot air outlet 12d, and prevents an abnormal temperature rise of the hot air outlet 12d.

  Reference numeral 24 denotes a temperature sensor A, which faces the hot air inlet 12e of the air blowing means 15, detects the hot air temperature after heating the waste in the waste storage container 4, and controls the driving of the electric motor 9. Then, control of the stirring timing of the rotary stirring blade 6 and determination of completion of drying are performed.

  Next, the operation of the soot processor will be described.

  When the hook 2b of the main body lid 2 is removed, the main body lid 2 is opened by the spring force with the hinge 2a as a fulcrum. At this time, the inner lid 11 is also lifted upward, and the upper surface opening of the garbage storage container 4 is exposed to the outside.

  Therefore, the garbage is stored in the garbage storage container 4, and then the main body lid 2 is closed. The body lid 2 is fixed by a body case 1 and a hook 2b.

  In this state, when a power switch (not shown) is turned on, the operation state is entered, and the electric motor 9 is driven for a predetermined time (about 5 seconds), and the rotary stirring blade 6 in the waste container 4 is moved to the left and right. It rotates forward and backward twice, and flattenes so that the waste in the waste storage container 4 is not biased. Thereafter, the electric motor 9 stops and the rotary stirring blade 6 also stops rotating.

  Further, when the power switch is turned on, the heating means 14 in the hot air circulating air passage case 12 and the catalyst heating means 17a in the catalyst deodorizing device 17 are heated, and the fan motor 15b of the blower means 15 is driven to circulate the fan 15a. And the exhaust suction fan 18 rotates. The wind generated by the circulation fan 15a rises in the hot air passage 12b as indicated by the arrow and becomes hot air while passing around the heating means 14, and further rises from the hot air outlet 12d to the periphery of the inner lid 11 of the main body lid 2. It passes through the hot air blowing part 11b opened in the side wall 11a, is guided by the cover guide 11d, and flows into the waste container 4 from the hot air blowing hole 11e of the inner lid 11.

  When the temperature of the hot air passing through the hot air inlet 12e reaches about 100 ° C., the temperature sensor A24 detects this and drives the electric motor 9 again, and the rotary stirring blade 6 in the garbage storage container 4 is rotated four times to the left. The forward and reverse rotation operations are repeated four times to the right, and the waste in the waste storage container 4 is stirred while being heated and dried. Further, the rotary stirring blade 6 and the convex portion 5 are crushed and reduced in cooperation.

  Thereafter, the hot air containing odor rises in the garbage storage container 4 and is sucked into the upper surface of the inner lid 11 from the hot air suction hole 11f of the inner lid 11, and further passes over the protruding wall 11g and reaches the hot air intake portion 11c. Then, it flows into the hot air air passage 12c from the hot air inlet 12e of the hot air circulation air passage case 12 as shown by the arrow, and flows out of the hot air air passage 12b from the communication port 13 again by the circulation fan 15a.

  Thereafter, this hot air circulation cycle is repeated to heat, dry, and reduce the waste in the waste storage container 4. At this time, the hot air blown out from the heating means 14 into the waste storage container 4 through the hot air outlet 12d by the blowing means 15 is controlled to be kept at about 145 ° C. by the temperature sensor B22. When this hot air rises to 150 ° C., it is determined that there is an abnormality, and the overheat prevention device 23 operates to stop the operation.

  On the other hand, a part of the hot air blown out by the circulation fan 15a of the air blowing means 15 passes from the vicinity of the inlet of the hot air outlet 12d through the gap between the metal case 14a and the case part 12g, the hot air branch port 16, and the branch pipe 16a, and the catalyst deodorizing device 17 The air is then deodorized and discharged by the exhaust suction fan 18 to the outside of the main body case 1 through the discharge port 18a.

  When heating, drying, and volume reduction of the waste in this state proceed, the moisture content of the waste in the waste storage container 4 decreases, and the temperature of the hot air passing through the hot air inlet 12e increases to about 120 ° C. . This is detected by the temperature sensor A24 and it is determined that the drying and volume reduction have been completed, and the electric motor 9 is deenergized and the rotation of the rotary stirring blade 6 is also stopped. At this time, energization to the heating means 14 is also stopped. The blowing means 15 and the catalyst heating means 17a are energized for a certain period of time thereafter, and the catalyst heating means 17a and the blowing means 15 are sequentially stopped to complete the operation.

  In the present invention, the catalyst deodorizing device 17 is provided with the sensor C17c and the sensor D17d, the sensor C17c is provided in the catalyst deodorizing device 17 so as to face the catalyst deodorizing device 17, and the catalyst deodorizing device 17 is maintained at a constant temperature. By controlling the output of the heating means 17a, the sensor D17d has been operated from a sudden temperature rise due to the type of soot and dust stored in the soot and dust storage container 4, and the current cannot be supplied. Thus, the temperature in the catalyst deodorizing device 17 is kept stable without being affected by the type, and the drying process can be performed to the end and the sensor D17d need not be replaced.

  Further, since the sensor C17c and the sensor D17d are provided above the catalyst 17b on the exhaust side 17f, the temperature change of the catalyst can be detected sensitively, and even when the temperature rise in the catalyst deodorizer is large, the catalyst deodorizer 17 The temperature can be detected stably without delaying the response, and the output to the catalyst heating means 17a is stopped, so that the catalyst 17b can be reliably protected.
