  And in the inside of the processor main body 10 of this embodiment, the processing tank 18 which accommodates garbage, and heater 25A, 25B which is the 1st and 2nd heating means which heats the garbage in this processing tank 18 is provided. The crushing rollers 26A and 26B, which are crushing means for crushing and discharging the processed dry waste from the processing tank 18, and a disposal container 31 for storing the processed shredded waste are disposed.

  The processing tank 18 is formed of a container having an inverted trapezoidal cross section in which an upper end thereof is disposed at a lower side edge of the charging port 14 and accommodates garbage in an inside communicated with the charging port 14. Specifically, the treatment tank 18 includes a rectangular tube-shaped upper portion 19 connected to the charging port 14 and a pyramid-shaped lower portion 20 continuous with the rectangular tube-shaped upper portion 19. An exhaust port 21 for exhausting the internal air is provided in the rectangular tubular upper portion 19 which is the upper portion of the treatment tank 18. The exhaust port 21 is connected to an exhaust duct 22 whose front end faces the outside from the back of the body 12, and a fan 23, which is an exhaust means for exhausting the air in the treatment tank 18, is interposed in the exhaust duct 22. Yes. A discharge port 24 having a horizontally long rectangular shape is provided at the lower end of the pyramidal lower portion 20 that is the lower end of the treatment tank 18.

  The heaters 25 </ b> A and 25 </ b> B are planar electric heaters for drying garbage in the treatment tank 18 to reduce weight and volume. Among them, the heater 25A that is the first heating unit (means) of the processing tank 18 is disposed on the outer peripheral surface of the pyramidal lower portion 20, and the heater 25B that is the second heating part (means) of the processing tank 18 is a rectangular tube. It is disposed on the outer peripheral surface of the upper portion 19. The heaters 25A and 25B are individually controlled by a microcomputer 49 described later.

  The crushing rollers 26A and 26B are rotatably disposed in the lower part of the discharge port 24 so as to shield the discharge port 24 of the processing tank 18 in the processing machine body 10 by a bearing member (not shown). Among them, one of the crushing rollers 26A has a first pulley 27 disposed on its rotating shaft, and an endless belt 30 is installed on a second pulley 29 disposed on the output shaft of a crushing motor 28 serving as driving means. Are connected by. Thus, when the crushing roller 26A is rotated counterclockwise by driving the crushing motor 28, the other crushing roller 26B is driven and rotated clockwise. As a result, the dry debris positioned above the crushing rollers 26A and 26B can be discharged to the outside of the processing tank 18 in a state of being crushed by the pressure.

  The waste container 31 is disposed at the lower part of the crushing rollers 26A and 26B, and has an upper end opening for receiving discharged crushing dust and a lower end closed. On both left and right sides of the waste container 31, take-out rails 32 having an inverted concave cross section are disposed so as to extend in the horizontal direction. Further, gripping handle portions 33 are provided on both front and rear sides of the disposal container 31.

  The bottom plate 13 is provided with a plurality of rotatable guide rollers 34 </ b> A to 34 </ b> D on which a removal rail 32 is placed via brackets as moving means for taking out the waste container 31 from the outlet 15. Among these, the guide roller 34A located in front of the left side in FIG. 3B is connected to a container moving motor 35 capable of normal rotation and reverse rotation so that the waste container 31 can be automatically taken out. Reference numeral 36 denotes a stopper for stopping the disposal container 31 at a predetermined mounting position.

  In the present embodiment, the processing tank 18 is provided with sensors 37A, 37B, and 37C as input amount detecting means for detecting the amount of raw garbage input into the processing tank 18. Among them, the sensor 37 </ b> A is disposed at a substantially intermediate position in the height direction in the pyramidal lower portion 20, which is the lower side of the processing tank 18. Incidentally, the input amount (volume) of the garbage at the position where the sensor 37A is disposed corresponds to the amount of garbage generated when cooking dinner for one adult. The sensor 37 </ b> B is disposed on the lower side in the height direction of the upper rectangular tubular upper portion 19, and the sensor 37 </ b> C is disposed on the upper side in the height direction of the rectangular tubular upper portion 19. These sensors 37 </ b> A to 37 </ b> C include, for example, a projecting unit such as a light emitting diode and a receiving unit that receives reflected light. The projection direction by the projecting unit is set in a horizontal direction, and the presence or absence of reception of reflected light by the receiving unit is determined. In this case, the presence / absence of thrown-in garbage up to that height is detected.

  In addition, a weight sensor 38 serving as a waste amount detecting means for detecting the amount of crushed dust accommodated in the waste container 31 is disposed on the bottom plate 13 which is a lower portion of the waste container 31. The weight sensor 38 is for detecting the weight of the mounted object. In this embodiment, the weight sensor 38 stores the weight of the waste container 31 in advance, thereby detecting whether or not the waste container 31 is attached. It is configured to play a role.

  In the garbage processing machine configured as described above, an operation panel 39 shown in FIG. 4 is disposed at a predetermined position on the front side of the processing machine body 10. The operation panel 39 includes an ON / OFF switch 40 for operating or stopping the entire device, a temporary stop switch 41 for temporarily stopping the operation, and a garbage processing state by the heaters 25A and 25B or the crushing roller 26A. , 26B, an in-process display 42 indicating a discharge processing state, a container non-mounting display 43 indicating that the disposal container 31 is not mounted, and a discharge for forcibly discharging garbage from the processing tank 18 to the disposal container 31. A switch 44 and a container removal switch 45 for taking out the waste container 31 are provided. The temporary stop switch 41 and the discharge switch 44 are provided with LEDs on the back to indicate the operation (execution) state of the switches by turning on and off. The container take-off switch 45 is provided with an LED (display means) on the back to indicate that the amount of waste in the waste container 31 is full.

  As shown in FIG. 5, in the garbage processing machine of this embodiment, a temperature sensor 46 is provided as temperature detecting means for detecting the heating temperature in the processing tank 18 by the heaters 25A and 25B. In addition, a pair of electrodes 47a and 47b are disposed in the processing tank 18 as means for detecting the moisture content of raw garbage. When a predetermined voltage is applied to the electrodes 47a and 47b from a voltage application circuit (not shown), a current flows using garbage as a conductor, and the magnitude of the current is proportional to the magnitude of the resistance value. Since it is approximately proportional to the amount of moisture contained in the waste, the moisture content can be detected. Further, a switch 48 that is turned on and off depending on the open / closed state is disposed at the hinge connection portion of the lid 11 as lid open / close detection means.

  A microcomputer 49, which is a control means provided on a control board (not shown), is operated according to a preset program by connecting a power outlet to a commercial power source. Specifically, when the user puts garbage into the treatment tank 18 and turns on the ON / OFF switch 40, the weight sensor 38 detects whether or not the waste container 31 is attached, and when the waste container 31 is attached. Allows garbage disposal to start.

  Specifically, the amount of raw garbage input in the processing tank 18 is determined by the sensors 37A to 37C, and when it is input, the raw garbage processing is executed, and when it is not input, a predetermined time elapses. The power is automatically shut off to stop operation. In the garbage disposal, the electrodes 47a and 47b detect whether the garbage is in a dry state or an undried state. If the garbage is in an undried state, the heating by the heaters 25A and 25B is controlled based on the input amount. When dry, the processed garbage is automatically discharged. Further, when the discharge switch 44 is operated in a state where dust is present in the processing tank 18, the discharge process is executed artificially.

  Next, the control by the microcomputer 49 will be specifically described.

  When power is turned on by the user operating the ON / OFF switch 40, the microcomputer 49 first executes input processing of the switches 40, 41, 44, and 45 in step S1, as shown in FIG. Thereafter, in step S2, the weight sensor 38 detects whether the waste container 31 is attached. If the disposal container 31 is attached, the process proceeds to step S3, and if not, the process proceeds to step S4.

  In step S3, it is detected from the detection value of the weight sensor 38 whether or not the inside of the waste container 31 is full. If the disposal container 31 is full, the process proceeds to step S4. If the disposal container 31 is not full, the process proceeds to step S5.

  In step S4, a notification sound is output by the piezoelectric buzzer mounted on the control board, and a notification process for turning on the container unmounted display 43 or the container removal switch 45 on the operation panel 39 is executed, and the process returns to step S1.

  In step S5, it is detected whether or not a pause is requested by operating the pause switch 41. If a temporary stop request is not made, the process proceeds to step S6. If a primary stop request is made, the process proceeds to step S7.

  In step S6, it is detected by the switch 48 whether or not the lid 11 has been opened. If the opening of the lid is detected, the process proceeds to step S7. If the opening of the lid 11 is not detected, the process proceeds to step S10.

  In step S7, after a stop process for stopping the operation of the heaters 25A and 25B and the fan 23 is executed, the process waits until the closed state of the lid 11 is detected by the switch 48 in step S8. When the closed state of the lid 11 is detected, in step S9, the process waits until the temporary stop state is released. If the temporary stop is released, the process proceeds to step S10.

  In step S10, an input amount determination process for determining the amount of raw garbage input into the processing tank 18 by the sensors 37A to 37C is executed. Note that this input amount determination processing is small when only the sensor 37A detects the presence of garbage, medium when the sensors 37A and 37B detect the presence of garbage, and all of the sensors 37A to 37C are raw. When the presence of garbage is detected, it is determined that the amount is large.

  When the amount of raw garbage input is detected, the process proceeds to step S12 if it is input in step S11 depending on whether or not the raw garbage is input into the processing tank 18, and to step S13 if it is not input. move on.

  In step S12, garbage processing is performed by operating the heaters 25A and 25B and the fan 23, and the process returns to step S1.

  On the other hand, in step S13, after 0 (end state) is input to the flag f indicating whether the garbage processing is being executed or completed, whether or not a predetermined waiting time has elapsed in step S14 after the garbage processing is completed. Detect whether or not. If the standby time has elapsed, the power is cut off and stopped, and if the standby time has not elapsed, the process returns to step S1.

  Next, the garbage processing in step S12 will be specifically described.

  In this garbage processing, as shown in FIG. 7, the microcomputer 49 first performs a moisture content determination process contained in the garbage stored in the processing tank 18 by the electrodes 47a and 47b in step S12-1. . In this moisture content determination process, the detected values by the electrodes 47a and 47b are compared with a preset threshold value, and when the detected value reaches the drying threshold value, it is determined that the dry state is reached, and the drying threshold is determined. When the value has not been reached, it is determined that the state is undried.

  When the moisture content of the raw garbage is determined, in step S12-2, it is detected whether the determination result based on the detection value and the drying threshold is in a dry state. If it is in a dry state, the process proceeds to step S12-3. If it is not in a dry state, the process proceeds to step S12-5.

  In step S12-3, a discharge process described later is executed, and in step S12-4, the heaters 25A and 25B and the fan 23 are stopped and the process returns.

  Also, in step S12-5, whether or not the flag f indicating whether or not the garbage processing is started after the garbage is input, that is, whether or not the garbage processing is being executed, is 0. Detect whether or not. And when f is 1 (execution state), it progresses to step S12-6, performs the temperature control process by heater 25A, 25B in operation, and returns. On the other hand, if f is 0 (end state), the process proceeds to step S12-7. In the temperature adjustment process, for example, the heater 25A is maintained at 120 ° C. when the input amount in the processing tank 18 is small, 135 ° C. when the amount is medium, and 150 ° C. when the amount is large. , 25B are turned on / off.

  In step S12-7, 1 is stored in f and 1 is stored, and in step S12-8, the fan 23 is turned on to start the exhaust process. Thereafter, in step S12-9, it is detected whether or not the input amount determined in step S10 is small. If the input amount is small, the process proceeds to step S12-10, where the first heater 25A is turned on and the second heater 25B is turned off, and the process returns. If the determined input amount is not small, the process proceeds to step S12-11.

  In step S12-11, it is detected whether or not the determined input amount is a medium amount. If the input amount is medium, the process proceeds to step S12-12, where the first heater 25A is turned on and the second heater 25B is turned on in a weak operation. If the determined input amount is not medium, the process proceeds to step S12-13, where the first heater 25A is turned on and the second heater 25B is turned on in the strong operation.

  Next, the discharging process in step S12-3 will be specifically described.

  In this discharging process, as shown in FIG. 8, the microcomputer 49 first turns on the crushing motor 28 to rotate the crushing rollers 26A and 26B in step S20, and then detects the sensors 37A to 37C in step S21. The discharge amount, that is, the remaining amount of dry dust in the processing tank 18 is detected by the value. If the remaining amount does not exist, the process proceeds to step S22, and if the remaining amount exists, the process proceeds to step S24.

  In step S22, the process waits until a predetermined waiting time elapses until all the heated and dried waste in the processing tank 18 is discharged to the disposal container 31, and then in step S23, the pulverization motor 28 is turned off and pulverization is performed. The rollers 26A and 26B are stopped and the process returns.

  In step S24, the weight sensor 38 determines whether or not the waste container 31 is full. When it is determined that the disposal container 31 is full, the process proceeds to step S25, and when it is determined that the disposal container 31 is not full, the process returns to step S21.

  In step S25, the crushing motor 28 is turned off to stop the crushing rollers 26A and 26B. Then, in step S26, a notification sound is output by the piezoelectric buzzer and a notification process is performed by turning on the container removal switch 45.

  Next, in step S27, the process waits until the container take-off switch 45 is operated. When the container take-off switch 45 is operated, a container take-out process is executed in step S28. In this container removal process, the lid opening / closing motor 17 is operated to open the container removal lid 16, the container moving motor 35 is operated to advance the waste container 31 from the front, and then the container moving motor 35 is stopped. is there. In this state, the user removes the waste container 31 from the guide rollers 34 </ b> A to 34 </ b> D and discards the crushed dust inside, and then installs the waste containers 31 on the guide rollers 34 </ b> A to 34 </ b> D again and operates the container take-off switch 45.

  That is, the microcomputer 49 waits until the container removal switch 45 is operated in step S29 when the container removal process is completed, and executes the container mounting process in step S30 when operated. In this container mounting process, the container moving motor 35 is operated to enter the waste container 31 until it abuts against the stopper 36, then the container moving motor 35 is stopped and the container opening / closing motor 17 is closed. It is.

  When the container mounting process ends, in step S31, the crushing motor 28 is turned on again to rotate the crushing rollers 26A and 26B, and the process returns to step S21.

  As described above, in the garbage processing machine of the present embodiment, the discharge port 24 below the processing tank 18 is provided with the pulverization rollers 26A and 26B that pulverize the garbage and discharge it to the lower waste container 31. The treated dry waste can be crushed and discharged from the treatment tank 18. Therefore, when the user throws in new garbage, dry garbage does not remain in the processing tank 18, so that discomfort can be prevented. Further, since the garbage drying process is only the garbage input at that time, it is possible to prevent the processing efficiency from being lowered. Furthermore, since the crushed garbage to be discarded is finer than the dried garbage, the volume at the time of disposal can be reduced.

  Further, since the drying process individually controls the heaters 25A and 25B based on the input amount of garbage, unnecessary power consumption can be prevented. In addition, since the container take-out switch 45 is provided with a display indicating that the amount of waste in the waste container 31 is full, the user can recognize the disposal time of the processed crushed garbage, thereby improving convenience. be able to. Furthermore, since the disposal container 31 can be automatically removed by operating the container removal switch 45, the workability when discarding the treated crushed waste can be improved.

  In addition, the garbage processing machine of this invention is not limited to the structure of the said embodiment, A various change is possible.

  For example, although the processing tank 18 is provided with two heating units using the heaters 25A and 25B, three or more heaters may be provided to perform more detailed heating control. The operation panel 39 is not limited to the processor main body 10 and may be disposed on the lid 11.

  Further, the waste amount detection means uses a plurality of sensors similar to the input amount detection means instead of the weight sensor 38, and detects the waste amount by detecting the height accommodated in the waste container 31. It is good. In this case, it is preferable to provide a switch for turning on or off when the disposal container 31 is mounted at the regular attachment position as the non-mounting detection means for the disposal container 31. Moreover, it is preferable that the configuration in which the full time is displayed as the amount of waste in the disposal container 31 by the LEDs provided in the container extraction switch 45 is displayed in a stepwise manner by a plurality of LEDs or the like.
