【Example】
Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. In FIG. 1, 15 is a garbage storage container for storing garbage, and 16 is a drying cabinet for storing the garbage storage container 15. A fixed blade 43 is provided on the inner wall of the garbage storage container 15. A stirring means 44 is a rotating blade which rotates while intersecting with the fixed blade 43, and is connected to the center shaft 46. The center shaft 46 is driven by a rotation motor 45. Reference numeral 17 denotes a lid. The tightness between the lid 17 and the food waste container 15 is maintained by pressing the packing 20 attached to the lid side to the food waste container 15. A drying heater 18 as a heating means and a blower fan 19 are provided below the lid 17, and are covered by a protective cover 49 provided with a plurality of openings 48. Reference numeral 21 denotes a discharge port provided inside the lid 17, and reference numeral 22 denotes an upper pipe connected to the discharge port 21, which is pressed through a connecting packing 24 to a lower pipe 23 connected to a deodorizing device 25 serving as a deodorizing means. 50 is a drying motor. On the exhaust side of the deodorizing device 25, there are provided a suction fan 27 and a suction motor 28 as exhaust means, and the exhausted air of the deodorizing device 25 is exhausted to the outside through a main body exhaust port 29.
[0016]
The deodorizing device 25 is provided with a catalyst 30 coated with a member that chemically decomposes an odor and a catalyst heater 31 for heating the catalyst 30 to promote a chemical reaction, and is housed in a metal case 32 and heated. The water vapor containing the odor generated from the garbage is discharged to the outside after the odor is removed by the deodorizing device 25.
[0017]
The suction motor 28 is provided with a cooling fan 33 and a suction fan 27, and a fan guide 36 is provided in front of the suction fan 27, and the exhaust of the deodorizing device 25 passes through a hose 37 and is connected to a connection portion 38 of the fan guide 36. Leads to. A gap of 2 to 5 mm is provided between the fan guide 36 and the suction fan 27 so that even if a foreign substance enters between the fan guide 36 and the suction fan, the rotation is not hindered. However, since the outer diameter of the fan guide 36 is substantially the same as the outer diameter of the suction fan 27 and covers the suction fan 27, the suction fan 27 can hardly suck outside air. Exhaust gas from the deodorizing device passing through 38 is sucked and discharged.
[0018]
The main body exhaust port 29 is opened below the suction fan 27 and the fan guide 36, and the ventilation of the cooling fan 33 dilutes the exhaust air of the suction fan 27 and discharges it to the outside of the main body. 40 is a control circuit.
[0019]
In the above configuration, the air heated by the drying heater 18 is sent into the garbage storage container 15 through the opening 48 by the blower fan 19 to heat the garbage. The steam generated from the heated garbage is discharged from the outlet 21 provided inside the lid 17 by being sucked by the suction fan 27, passes through the upper pipe 42 connected to the outlet 21, and It passes through the lower pipe 23 connected to the deodorizing device 25 via the connecting packing 24 and reaches the deodorizing device 25. Then, after the odor is removed by a chemical reaction in the deodorizing device 25, the odor is cooled to a temperature around room temperature by the cooling fan 33, and is discharged to the outside through the main body exhaust port 29. At the same time, the garbage is dried while being stirred and pulverized by the rotating blade 44 rotating while intersecting with the fixed blade 43, and after the drying is completed, the weight is reduced and divided.
[0020]
Reference numeral 51 denotes an infrared sensor that measures the temperature distribution in the food waste container 15 and reads the temperature distribution on the entire surface of the food waste container 15. The read information is arithmetically processed in the control circuit 40, and performs the following control according to the situation.
[0021]
If the temperature of the garbage surface does not reach the target temperature (temporarily set to 105 ° C.), the input of the drying heater 18 is kept ON so that the garbage is always heated. When the temperature on the garbage surface reaches the set temperature, the rotary blade 44 is rotated to agitate the garbage.
[0022]
Thereafter, when the temperature of the food waste surface rises sharply (when the rising gradient of the output value of the infrared sensor 51 is larger than a predetermined value), the drying speed is too fast. By increasing the input of the catalyst heater 31 to promote the chemical reaction of the catalyst 30 and enhance the deodorizing performance, generation of odor is prevented. At the same time, the number of rotations of the suction fan 27 is reduced, and the amount of steam sucked into the deodorizing device 25 is suppressed, so that only the amount of steam that can be reliably deodorized by the deodorizing device 25 is sucked, thereby suppressing odor generation.
[0023]
When the temperature distribution on the garbage surface becomes uneven (when the temperature distribution of the garbage detected by the infrared sensor 51 is large), it is determined that the garbage is in a dumpling shape, and 44, the frequency of stirring is reduced, the time of one stirring is shortened, the movement of the refuse is suppressed, the number of reversals is increased, and the garbage that has become dumped is crushed by switching the rotation direction in small increments.
[0024]
When the infrared sensor 51 detects that the surface of the food waste has all substantially uniformly reached the target temperature or higher, it is determined that the drying has been completed, and the process proceeds to the cooling step after a lapse of a predetermined time (temporarily set to 10 minutes). When the surface temperature of the garbage becomes about 60 ° C., the odor is not tight even when the lid is opened, and there is no danger of burns.
[0025]
These controls can be controlled by performing arithmetic processing only with information from the infrared sensor 51, so that a simple configuration can be performed, and fine control can be performed. Thus, a garbage disposer with a good finished state can be provided in a short time.
[0026]
