Whether the stocker 4 is put in the outer shell case 10 or taken out from the outer shell case 10 can be detected by turning on / off the reed switch. Further, in the case of the stocker 4 of the present example, since the above-mentioned discharged matter tends to be highly accumulated in the portion near the front plate 4a, the front side piece 4e is integrally projected from the side plate 4b upward.

As described above, the discharge product discharged from the overflow hole 3 through the duct 13 is received by the stocker 4, but the full detection means 5 for detecting whether the discharge product accumulated in the stocker 4 is full or not. 4 is arranged above. The fullness detecting means 5 is, for example, an optical sensor, and the light emitting element 5a and the light receiving element 5b are arranged to face each other so as to sandwich the stocker 4. In the case of the example of FIGS. 1 and 2, the light emitting element 5a and the light receiving element 5b are provided at a position above the entry corner between the side plate 4b of the stocker 4 and the front side piece 4e.
And are placed. Then, when discharge is accumulated in the stocker 4 and the light receiving element 5b no longer receives the light of the light emitting element 5a, the fullness is detected. The light emitting element 5a and the light receiving element 5b may be arranged at a position above the front piece 4e as shown in FIG. In this case, the through hole 14 is formed in the upper portion of the front side piece 4e, and the light emitting element 5a and the light receiving element 5b are arranged outside the through hole 14.

Further, the food waste processing apparatus is provided with a person detecting means 6 for detecting whether or not a person is present near the food waste processing apparatus. In the case of this example, the person detecting means 6 is adapted to detect whether a person is in the vicinity or not depending on whether the person opens or closes the lid 7. That is, the push button 6a of the switch is projected as the person detecting means 6 on the upper surface of the outer shell case 10, and by opening and closing the lid 7, the switch is turned on and off so that the presence of a person can be detected. Has become. Further, a notifying means (not shown) such as a buzzer for notifying when the discharger of the stocker 4 is full is incorporated in the food waste processing apparatus. In the case of the present invention, when the fullness detection means 5 detects the fullness of the stocker and the person detection means 6 detects the presence of a person, the notification means such as a buzzer is used. That is, as shown in FIG. 4, when the optical sensor which is the fullness detecting means 5 detects the fullness of the stocker 4, the lid 7 is opened and the person detecting means 6 detects a person, the buzzer is full. Be informed. At this time, when the lid 7 is closed, the buzzer notification is stopped, but the lead switch for detecting the presence / absence of the stocker 4 is not turned on and off without putting the stocker 4 in and out (if the discharged matter of the stocker 4 is not discarded. When the lid 7 is reopened, a buzzer notification is given. When the reed switch that detects the presence / absence of the stocker by inserting / removing the stocker 4 is turned on / off (it is considered that the stocker is taken in / out and the waste is discarded), the maintenance completion of the disposal is detected and the buzzer notification is released. It is like this.

An exhaust deodorizer 16 is arranged outside the food waste treatment tank 1 in the outer shell case 10. The deodorizer 16 heats the platinum catalyst to heat and deodorize the exhaust. An exhaust gas intake port 17 is provided on the end surface of the garbage processing tank 1, an exhaust pipe line 18 is arranged between the exhaust gas intake port 17 and the deodorizer 16, and an exhaust fan 19 is provided in the exhaust pipe line 18.
Has been placed. Then, when the exhaust fan 19 is driven, the exhaust gas in the raw garbage processing tank 1 is sucked from the exhaust gas intake port 17 and guided to the deodorizer 16 via the exhaust pipe line 18 to be heated and deodorized by the deodorizer 16 to deodorize. The exhaust gas generated is the dilution chamber 22.
It is diluted and exhausted to lower the temperature. Further, the outer shell case 10 is filled with outside air, and the outer shell case 1

The air inside the outer shell case 10 is sucked into the outer shell case 10 from the intake port 20 by depressurizing the inside of the garbage processing tank 1 by driving 9. An intake path is formed in the outer shell case 10 from the intake port 20 to the periphery of the deodorizer 16, the stocker 4, the duct 13, and the overflow hole 3 to the inside of the garbage processing tank 1. The air outside the formed outer shell case 10 can be introduced into the food waste treatment tank 1 through the intake path. Accordingly, the deodorizer 16 can be cooled by the air sucked from the outside of the outer shell case 10 and the air warmed by the deodorizer 16 can be sucked into the garbage processing tank 1 to improve the thermal efficiency. . Further, the stocker 4 can be ventilated and the discharged matter can be dried.

Next, another embodiment of the present invention will be described with reference to FIGS. Since the structure of the food waste processing apparatus in this embodiment is the same as that of the above-described embodiment shown in FIG. 1, description thereof will be omitted and only different points will be described. As described above, the fullness detecting means 5 for detecting whether or not the discharged matter accumulated in the stocker 4 is full is arranged above the stocker 4, and, for example, the fullness detecting means 5 is an optical sensor, The light emitting element 5a and the light receiving element 5b are arranged so as to face each other so as to sandwich them. By the way, the discharge from the garbage processing tank 1 is discharged to the stocker 4 at the time of stirring by the stirring blade 2. However, since the discharge just discharged from the garbage processing tank 1 is at a high temperature, steam is generated. However, due to this steam, the fullness detection means 5 may erroneously detect the fullness even if it is not full. That is, in the case where the notification control is performed by the notification means in the flowchart as shown in FIG. 8, erroneous detection due to steam may occur. Therefore, in order to prevent this, in the present embodiment, the full detection means The control unit 31 controls so that the detection of No. 5 is ignored during the stirring by the stirring blade 2 and for a fixed time (x minutes) after the stirring is finished and the notification is not performed by the notification unit. FIG. 6 shows a control block, and FIG. 7 shows a flowchart of this embodiment. Reference numeral 14 in the drawing denotes an operation unit.

In this embodiment, however, when the fullness detecting means 5 detects fullness, the buzzer, the lamp, etc. are turned on during the stirring by the stirring blade 2 and during a predetermined time set after the stirring blade 2 is finished. When the fullness detection means 5 detects the fullness without notifying the notification means, the fullness state is indicated by the notification means during the stirring by the stirring blades 2 and in the time period other than the preset fixed time after the stirring blades 2 complete the stirring. It is supposed to inform you. As a result, it is possible to prevent erroneous detection by the full-fill detecting means 5 due to steam generated from the discharged matter.

By the way, the garbage processing apparatus is provided with a jumper wire in the substrate and is energized while the jumper wire is connected so that it can be switched to the inspection mode in order to carry out the inspection in the manufacturing process. After the inspection, the jumper wire is cut off to allow normal operation, but this one requires a jumper wire and costs more, and when the inspection is over, the jumper wire must be removed. There is a problem that it is necessary to cut and ship it, and it takes time and effort for cutting. FIG. 11 shows a flowchart for shifting to the inspection mode. Therefore, the deodorizing switch 16a for operating the deodorizing device 16 as shown in FIG. 10 provided in the operating unit 24 of the food waste processing device is effectively utilized, and the deodorizing switch 16a provided in the operating unit 24 is pressed and the outlet is provided. Deodorizer 1 by connecting to the power supply
It is set so that the inspection mode for the process inspection is started immediately after connecting to the power source without turning on and off 6. When the inspection mode is entered, the loads are sequentially turned on and each function is checked in the process inspection. Then, when the inspection is completed, the outlet can be pulled out from the power source to exit the inspection mode. After the inspection is completed and the product is shipped, when it is used, the outlet is connected to a power source (in this case, the deodorizing switch 16 is not pressed at the same time as the power source is connected) to start the operation as the food waste processing device. It is a thing. FIG. 9 shows a flowchart of this embodiment. By doing this, there is no need for a jumper wire to enter the inspection mode, and
It also saves the trouble of cutting the jumper wire.

A water content sensor 25 is provided on the side surface of the food waste processing tank 1. The water content sensor 25 allows the food waste processing tank 1 to operate.
As shown in the control block diagram of FIG. 14, the stirring blade 2 and the exhaust fan 19 are detected based on the water content of the raw garbage processing material detected by the water content sensor 25. Alternatively, the operation control of the surface heater 40 and the like provided on the side surface of the garbage processing tank 1 is performed.

As shown in FIG. 13, this moisture content sensor 25 generally has a heater element 26 and a temperature sensor element 27, which is separate from the heater element, incorporated in a sensor frame 28, and the sensor frame 28 is placed in a recess 29a of a casing 29. The filling material 29b was filled in the recess 29a, and the casing 29 was attached to the side surface of the food waste disposal tank 1. The moisture content sensor 25 detects the temperature before the heater element 26 is turned on and the temperature when the heater element 26 is driven at a constant duty for a certain period of time by using the temperature sensor element 27, and generates the temperature change data from the temperature sensor element 27. The water content of the waste treatment material is calculated. That is, since the temperature change by the temperature sensor element 27 is different when the water content of the food waste treating material is different, the water content can be obtained by detecting the temperature change by the temperature sensor element 27.

By the way, in the case where the heater element 26 and the temperature sensor element 27 are simply incorporated in the sensor frame 28 as described above, the positional accuracy of the heater element 26 and the temperature sensor element 27 is poor and the accuracy of detecting the water content is low. There is a problem that it is bad, but as shown in FIG.
The heater element 26 and the temperature sensor element 27 are mounted on the printed circuit board 30, the printed board 30 is placed in the recess 29a of the nursing 29, the filling material 29b is filled in the recess 29a, and the casing 29 is attached to the side surface of the garbage processing tank 1. Install on the part. This improves the accuracy of the positional relationship between the heater element 26 and the temperature sensor element 27 and improves the accuracy of detecting the water content. Reference numeral 35 in the drawing is a lead wire.

As shown in FIGS. 18 and 19, in the food waste processing apparatus provided with the water content sensor 25 as described above, a heater is provided to prevent ignition or smoke when the microcomputer constituting the control means 31 runs out of control. The drive circuit 32 is provided with a safety circuit 33 including a CR time constant circuit 36, a comparator 37 and a reference voltage generating circuit 38. Reference numeral 34 in the drawing is a temperature detection circuit. The duty drive signal output from the control means 31 including a microcomputer is cut off when it detects that the duty drive signal is no longer a pulse when the microcomputer which is the control means 31 runs out of control. That is, the water content sensor 25 is energized through the heater driving circuit 32 by the heater driving duty signal A output from the microcomputer. Here, as shown in FIG. 20, the duty signal A for driving the heater is the CR time constant circuit 36 and the comparator 37.
It is input to the safety circuit 33 including the reference voltage generation circuit 38, and the heater drive circuit 32 is cut off or connected. The heater driving duty signal A input to the safety circuit 33 is input to the CR time constant circuit 36, the output B of the CR time constant circuit 36 is compared with the reference voltage C by the comparator 37, and the heater drive circuit 32 is shut off. Alternatively, the connection is determined.

As shown in FIG. 20, when the duty of the specified pulse width is output during normal operation, the comparator 3
The peak value of the voltage input to 7 is below the reference voltage C,
The comparator 37 is adapted to output D. On the other hand, if the duty signal A of a certain pulse width or more is output during abnormal operation (due to microcomputer runaway due to noise, microcomputer hardware failure, malfunction due to programming bug, etc.), CR time constant Since the output B of the circuit 36 exceeds the peak value reference voltage C of the voltage, the comparator 37 cuts off the output D, the heater output is stopped, and the ignition and smoke due to abnormal overheating of the water content sensor 25 are prevented. There is.

However, in the safety circuit 33 as described above, the CR time constant circuit 36 is provided to determine whether or not a pulse output is produced, and the circuit configuration becomes complicated and the number of parts increases.

Therefore, by configuring as shown in FIGS. 15 to 17, the circuit configuration can be simplified.

That is, in this embodiment, the voltage is input to the microcomputer constituting the control means 31 through the temperature detection circuit 34 of the temperature sensor element 27 of the water content sensor 25. In addition, the heater driving circuit 32 energizes the heater element 26 of the water content sensor 25 by the heater driving duty signal A output from the microcomputer constituting the control means 31.

Here, the safety circuit 33 of this embodiment is as follows. That is, the output B from the temperature sensor element 27 is input to the comparator 37, and is compared with the voltage C of the reference voltage generation circuit 38 to be compared with the heater drive circuit 32.
It is designed to cut off or connect to.

Therefore, in this embodiment, as shown in FIG.
As shown in (1), since the output B from the temperature sensor element 27 exceeds the reference voltage during normal operation, the comparator 37 determines that the heater drive circuit 32 is an output (connection). On the other hand, if the duty signal is output at a high duty ratio during abnormal operation (microcomputer runaway due to noise, microcomputer hardware failure, malfunction due to programming bug, etc.), heating by the heater element 26 is set. When the temperature exceeds the heating temperature, the temperature detected by the temperature sensor element 27 increases, and the output voltage E of the temperature sensor element 27 increases.
When the voltage becomes lower than the set reference voltage C, the comparator 3
It is determined that 7 shuts off the heater drive circuit 32, shuts off the output of the heater drive circuit 32, stops the heater output, and prevents ignition and smoke due to abnormal overheating of the water content sensor 25.

With the circuit configuration of this embodiment, C
The R time constant circuit 36 becomes unnecessary, and the number of parts can be reduced.
