JP-A-6-345201

  In this Patent Document 1, a human body detection sensor for detecting a human body approaching the upper front of the box main body is provided in order to open the lid without touching the trash box and enable the input of garbage. When the human body is detected by the human body detection sensor, the lid can be automatically opened.

  However, in this patent document 1, there is a problem that the user feels bothered because the lid is opened simply by passing a person in front of the trash can. In addition, when the lid is opened, odor is released from the raw garbage thrown into the box body.

  Therefore, an object of the present invention is to provide a garbage disposal machine that can reliably open a lid only when garbage is introduced.

  In order to solve the above-mentioned problems, a garbage processing machine of the present invention has a processing tank for processing garbage inside, a processing machine main body installed with a predetermined gap between the floor and the processing machine. A lid that is attached to the main body so as to be openable and closable, and is biased in an opening direction by a biasing means, and closes the charging port of the processing tank; A detecting means for detecting the presence or absence of an intruding object with the floor surface, having a preset detectable range, the floor surface being located outside the detectable range, and the detection When the means detects an entering object, the structure is provided with a lid opening means for releasing the lock by the locking means and opening the lid.

  According to this garbage processing machine, in order to detect the thing which entered into the crevice between a processing tub and a floor, specifically, a user's leg, a lid body is only passed around the processing machine main part. The problem of opening up can be prevented. As a result, an unpleasant odor can be prevented from being released due to inadvertent opening of the lid.

  In this garbage processing machine, it is preferable to further provide a trapezoidal cylindrical case in which the detection means is disposed at a predetermined height from the bottom of the processing machine main body. In this way, since the detectable area can be limited, unintentional opening of the lid can be further prevented.

  In this case, the detecting means includes a light emitting element that emits infrared light and a light receiving element that receives reflected light, and the inner surface of the case is preferably dark. If it does in this way, it can prevent that a light receiving element receives the irregularly reflected light by the light which the light emitting element projected, and a cover body will open carelessly.

  Further, it is preferable that the lock means is composed of a rotatable lock member having a claw portion that is engaged with the lid body, and the lid body opening means is composed of a solenoid that rotates the lock member. In this way, the configuration of the locking means can be simplified, the cost can be reduced, and the lid can be reliably opened with short-time energization.

  In this case, it is preferable that the processor main body further includes a manual unlocking operation unit that directly rotates the lock member. If it does in this way, when it cannot open automatically via a detection means for a certain reason, a cover body can be reliably forcibly opened.

  In the garbage processing machine of the present invention, the lid is automatically opened by detecting an object that has entered the gap between the processing tank and the floor surface. The problem that the body is released can be prevented. As a result, an unpleasant odor can be prevented from being released due to inadvertent opening of the lid.

It is. The light emitting element 49 is composed of an infrared light emitting diode (LED), and the projection direction thereof is configured to be substantially perpendicular to the floor surface F. The light receiving element 50 detects the presence or absence of an entering object by receiving the reflected infrared light projected by the light emitting element 49. In this embodiment, the light receiving element 50 is used for detecting an optical spot position using a photodiode (PD). PSD (Position Sensitive Photodetector = semiconductor position detecting element) is used. In the distance measuring sensor 46, a range (distance) L that can be detected by the amount of light emitted from the light emitting element 49 is set in advance. And in this embodiment, it arrange | positions so that the floor surface F may be located out of the detectable range L, and it is set as the structure which detects the presence or absence of an approaching object between the floor surfaces F.

  The case 52 is for arranging the distance sensor at a predetermined height from the bottom plate 13 of the processor body 10 so that the floor surface F is located outside the detection range L of the distance sensor 46. Considering that the projection light from the light emitting element 49 is diffused, it has a substantially cross-sectional trapezoidal cylindrical shape. An attachment portion 53 for fixing the distance measuring sensor is provided at the upper end of the case 52. Further, the inner surface of the case 52 is colored in a dark color (black in this embodiment) in order to prevent the projection light from being irregularly reflected.

  As shown in FIG. 1, the lid 54 is rotatably attached to the upper surface of the lid frame 14 constituting the processor main body 10 and is urged in the opening direction by a hinge spring 55 which is an urging means. It is a thing. As shown in FIG. 4, a locking receiving portion 56 protruding downward is provided at the front portion of the lid 54, and the locking receiving portion 56 is locked and unlocked by a locking means.

  The locking means includes a lock member 57 that is rotatably attached to the lid frame 14 and that has a claw portion 59a that engages with the engagement receiving portion 56. Specifically, the locking member 57 is provided with a locking portion 59 provided with a claw portion 59a at the tip so as to protrude above a bearing portion 58 that is pivotally attached to the lid 54. The bearing portion 58 is provided with an action portion 60 that protrudes in a substantially L shape and extends downward. The action portion 60 is always urged upward by the lock member 57 by the spring 61, which is the lock position. Further, a rod 62 a of a solenoid 62 constituting a lid opening means for automatically opening the lid 54 by detecting the human body by the distance measuring sensor 46 is connected to the operating portion 60 via a link member 63. Further, a manual unlocking operation portion 64 is disposed on the lid frame 14 so as to be positioned in front of the action portion 60 in a state of being biased outward by a spring. The unlocking operation portion 64 is provided with a pressing piece 65 extending to the vicinity of the action portion 60. Reference numeral 66 denotes a compulsory locking member that makes it impossible to open the lid 54 both automatically and manually. Reference numeral 67 denotes a switch for detecting that the lid 54 is closed. The switch 67 can detect the opening and closing of the lid 54 by being turned on and off by an arcuate pressing member 54 a protruding from the lid 54.

  In the garbage processing machine configured as described above, as shown in FIG. 5, the substrate state for detecting the state of the processing function for decomposing the garbage with the bio-substrate accommodated in the processing tank 20. As detection means, three temperature sensors 68, 69, and 70 for detecting the temperature in the processing tank 20, the temperature of the bio-base material, and the temperature of the outside air are arranged. The processing tank temperature sensor 68 is disposed in the space temperature above the bio-substrate in the processing tank 20. The substrate temperature sensor 69 is disposed on the bottom in the processing tank 20. The outside air temperature sensor 70 is disposed on the exterior body 11 of the processor main body 10.

  And the microcomputer 72 which is a control means mounted on the control board 71 is operated according to a preset program. Specifically, the microcomputer 72 operates by converting electric power from a commercial power source into a DC voltage by the power supply circuit unit 73 and applying the DC voltage. When it is detected by the switch 67 that the lid body 54 is closed, the heater 45 is turned on and off, and the rotation of the stirring member 25 is controlled with the control time being the starting point. Furthermore, it plays the role of the base material state determination means for determining the state of the processing function of the bio base material based on the detection values by the temperature sensors 68 to 70 which are the base material state detection means at predetermined time intervals, and based on the determination result The heater 45 is turned on and off, and the rotational speed of the stirring member 25 is controlled, and the state of the bio-substrate treatment function is displayed on the display unit of the operation panel 74.

  The microcomputer 72 of the present embodiment serves as a lid opening control means, and as shown in FIG. 6, a preset acceptance judgment that an object including a human body has approached a range that can be detected by the distance measuring sensor 46. When the detection continues for a time (2 seconds) or longer, the solenoid 62 is operated, and the latch receiving portion 56 is unlocked by the latching portion 59, whereby the lid body 54 is applied by the biasing force of the hinge spring 55. Is automatically opened. Further, when the opening operation of the lid body 54 is received by continuously detecting the reception determination time by the distance measuring sensor 46, a reception sound is notified by a piezoelectric buzzer mounted on the control board 71, and the reception state is notified to the user. Inform. Further, when the lid 54 is opened by energizing the solenoid 62 (1 second), the energization prohibition prohibits energization of the solenoid 62 for a predetermined time (6 seconds) after energization to protect the solenoid 62. When the opening of the lid 54 is received within the energization prohibition time, the solenoid 62 is energized after the energization prohibition time has elapsed to open the lid 54.

  In the garbage processing machine of the said structure, in order to detect the thing which approached into the clearance gap S between the baseplate 13 and the floor surface F of the processing tank 20, specifically, a user's leg, it passed the vicinity of the processing machine main body 10. FIG. It is possible to prevent the inconvenience that the lid 54 is opened. As a result, an unpleasant odor can be prevented from being released due to the lid 54 being inadvertently opened. In addition, since the lid 54 can be opened without the user's hand, the throwing-in garbage can be reliably supported with both hands, so that inconveniences such as spilling the garbage around can be prevented.

  In addition, since the distance measuring sensor 46 for detecting an approaching object that is a foot of a human body is adjusted by the case 52 so that the floor surface F is located outside the detectable range L, erroneous detection is performed. The possibility can be prevented. In addition, since the area that can be detected by the case 52 can be limited, the unintended opening of the lid 54 can be further prevented. In addition, since the inner surface of the case 52 is dark, it is possible to prevent the light receiving element 50 from receiving irregularly reflected light due to the light projected by the light emitting element 49 and opening the lid 54.

  Further, the lid opening means of the lid 54 is composed of a solenoid 62 having a rod 62a pivotally attached to the lock member 57 via the link member 63, so that the configuration is simple and the size can be reduced. The cost can be reduced, and the lid 54 can be reliably opened with a short period of energization. In addition, since the manual unlocking operation unit for directly rotating the lock member 57 is further provided, the lid 54 can be reliably forcibly opened when it cannot be automatically opened for some reason.

  Next, the control by the microcomputer 72 will be specifically described.

  When the power is turned on, as shown in FIG. 7, the microcomputer 72 first resets and starts the built-in time timer 75 in step S1, and then elapses (counts up) in step S2. ) Is detected. If the set time has elapsed, the process proceeds to step S3. If the set time has not elapsed, the process proceeds to step S5.

  In step S3, 1 is input to the flag fa indicating that a predetermined time has elapsed after the power is turned on. Then, in step S4, the time counting timer 75 is stopped and the process proceeds to step S5.

  In step S5, a garbage disposal control process described later is executed, and the process proceeds to step S6. In step S6, it is detected whether 1 is input to the flag fa. If fa is 1, the process proceeds to step S5. If fa is not 1 (fa = 0), the process returns to step S2. That is, after a predetermined time has elapsed after the power is turned on, only the garbage processing control process of step S5 is performed. Here, the set time is necessary for judging the usage status of the user or activating the bio-base material, such as when purchasing a new garbage processing machine or replacing the internal bio-base material. It ’s a great time.

  Next, the garbage disposal control process in step S5 will be specifically described.

  In this garbage disposal control process, as shown in FIG. 8, the microcomputer 72 first executes a lid opening process described later in step S10. In step S11, if the lid 54 is opened by the lid opening process, the process proceeds to step S12. If the lid 54 is not opened, the process proceeds to step S16.

  In step S12, after the stirring member 25 is stopped, the process waits until it is detected in step S13 that the lid 54 is closed via the switch 67. When the closure of the lid 54 is detected, in step S14, a 2-hour timer that is a cycle for detecting the state of the processing function of the bio-base material is reset and started, and then in step S15, a bio-base material to be described later The data of the stirring cycle for operating the stirring member 25 is read in the stirring means control process which is one of the adjustment processes, and the process proceeds to step S16.

  In step S16, it is detected whether or not the 2-hour timer has counted up. If it has been counted up, the process proceeds to step S17, and if it has not been counted up, the process proceeds to step S21.

  In step S17, the two-hour timer is reset and started in order to detect the state of the processing function of the bio-base material, and thereafter, in step S18, the three temperature sensors 68 to 70 which are base-material state detection means. Thus, the temperature in the processing tank 20, the temperature of the bio-base material, and the temperature of the outside air are detected.

  Next, in step S19, after executing the base material state determination process for determining the state of the bio base material based on the detected three temperatures, in step S20, based on the determined state of the bio base material processing function. The display unit of the operation panel 74 is changed, and the process proceeds to step S21.

  In step S21, a bio-base material adjustment process including a control process for the stirring means including the motor 26 and the stirring member 25 and a heating means control process using the heater 45 is executed, and the process returns. In the agitation means control process, the first agitation operation having an operation time for reversing the agitation member 25 and the second agitation operation for rotating the agitation member 25 in the normal direction for all the operation times are operated in a preset agitation cycle. Is. Further, the heating means control process changes the heating time by the heater 45 based on the state of the bio-substrate processing function determined in step S19.

  Next, the lid opening process in step S10 will be specifically described.

  In the lid opening process, the microcomputer 72 first detects whether or not an entering object has entered the gap S by the distance measuring sensor 46 in step S10-1, as shown in FIG. If entry is detected, the process proceeds to step S10-2. If entry is not detected, the process returns.

  In step S10-2, after resetting and starting the reception determination timer for determining whether to accept the opening of the lid 54, it is detected in step S10-3 whether the reception determination timer has been counted up. To do. If the reception determination timer has not counted up, the process proceeds to step S10-4. If the reception determination timer has counted up, the process proceeds to step S10-5.

  In step S10-4, the distance measuring sensor 46 detects whether or not the detection of the entering object is continued. And when the detection of an entering object is continuing, it returns to step S10-3. On the other hand, when the detection of the entering object is not continued, that is, when the detection of the entering object by the distance measuring sensor 46 is interrupted, it is determined that a small animal or the like has passed or the user has stopped discarding, and the process returns.

  If the acceptance determination timer counts up, in step S10-5, the opening of the lid 54 is accepted and a notification sound is output to inform the user of the situation, and then in step S10-6, the solenoid 62 is turned on. It is detected whether or not the energization prohibit timer is counting up. If the timer is counting up, the process proceeds to step S10-7. If the timer is not counting up, the process waits until counting up and waits for step S10-7. Proceed to

  In step S10-7, the solenoid 62 is energized to release the locking of the lid 54 by the lock member 57, and the lid 54 is opened by the biasing force of the hinge spring 55, and then step S10- At 8, reset the energization prohibit timer and start and return.

  As described above, in this embodiment, once the solenoid 62 constituting the lid opening means is energized, energization to the solenoid 62 is prohibited for a predetermined time after the energization. Even if it uses, sufficient protection is possible and it can always be operated stably.

  In addition, when a human body is detected by the distance measuring sensor 46 within the time when the solenoid 62 is not energized, the detection state is notified and notified, so that the user tries to automatically open the lid 54 for the purpose of throwing in garbage. Nevertheless, it is possible to prevent the user from feeling uncomfortable due to the lid 54 not being opened. In addition, since the lid 54 is automatically opened at an unintended timing, it is possible to prevent the lid from coming into contact with the user and causing discomfort.

  In addition, if the distance measuring sensor 46 does not detect a human body continuously for a predetermined time or longer, the lid 54 is not opened, so that it passes through the vicinity of the processor main body 10 or only passes through other objects. It is possible to prevent the lid body 54 from being prepared.
