Description

  The present invention mainly relates to a household garbage processing machine.

  Household garbage processing machines include a crushing method for finely crushing garbage, a drying method for reducing weight and volume by eliminating moisture in the garbage, and an aerobic biobacteria supported on a substrate. There are three types of biosystems that ferment and decompose garbage with bio-base materials.

  These garbage processing machines include a processing machine main body having a processing tank for processing garbage inside, a lid attached to the processing machine main body so as to be openable and closable, and closing a charging opening of the processing tank, and the lid Locking means for locking the body and the processor main body so as not to be opened is provided.

  However, because garbage such as adhering moisture drops, the garbage is often thrown into the processing machine while covering the lower part with hands. In such a state where both hands cannot be used, the lock by the locking means is released. It is very difficult to open the lid.

  Prior art document information relating to a trash box into which this kind of garbage including the garbage processing machine of the present invention is placed includes the following.

JP-A-6-117528

  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 open a lid only when garbage is thrown in.

  In order to solve the above-mentioned problems, a first garbage processing machine according to the present invention includes a processing machine main body having a processing tank for processing garbage inside, and an openable and closable attachment to the processing machine main body. In a garbage processing machine comprising a lid for closing the opening and a lock means for locking the lid to the main body of the processor, the first human body detecting means for detecting a human body, and the installation position of the floor surface When both the second human body detecting means for detecting a human body in the vicinity of the detection range and the first and second human body detecting means detect the human body, the lid that releases the lock by releasing the lock by the locking means. The opening means is provided.

  In this garbage processing machine, the main body of the processing machine is provided with a rotatable stirring means inside the processing tank and accommodates a bio-base material in which an aerobic bio-fungus is supported on the base material. The bio method is preferred.

  In addition, a base material state detecting means for detecting the state of the processing function based on the moisture content of the bio-base material is provided, and when the processing function by the bio-base material is determined to be low, unlocking of the lock means by the lid opening means It is preferable to make this impossible.

  In this case, it is preferable to provide display means for displaying a state in which the lock means cannot be unlocked.

  Furthermore, it is preferable that the second human body detecting means detects that the human body is approaching by detecting electrostatic capacity.

  Furthermore, it is preferable to provide forcibly releasing means for locking means by the lid opening means.

  Further, a second garbage processing machine of the present invention includes a processing machine main body having a processing tank for processing garbage inside, and a lid attached to the processing machine main body so as to be openable and closable, and closing the charging opening of the processing tank. In a garbage processing machine provided with a body and a lock unit that locks the lid to the main body of the processor so as not to be opened, a human body detection unit that detects the presence or absence of a human body, and a request to open the lid When the switch detects the human body and the switch receives a request to open the lid, the lid opening means releases the lock by the locking means and opens the lid It is set as the structure provided.

  In the first garbage processing machine of the present invention, when the user approaches to throw in the garbage, both the first human body detecting means and the second human body detecting means detect the human body, so that the lid is automatically opened. . Therefore, the user can reliably throw in the garbage without touching the garbage processor. In addition, when the user passes near the garbage disposal machine or when any object is located in the vicinity, the first human body detection unit and the second human body detection unit do not detect the human body at the same time. The lid can be prevented from automatically opening. Therefore, it is possible to prevent the user from being bothered and uncomfortable due to the smell.

  In addition, since the lid cannot be opened automatically when the bio-base processing function is low, the period of use (durability) of the equipment including the bio-base can be increased by adding too much garbage. It can be secured. And since the display means which displays the unlocking impossible state by the locking means is provided so as to inform the user of the unusable state, it is possible to prevent the user from being distrusted due to the inability to use.

  Further, since the second human body detection means detects the approach of the human body by detecting the capacitance, the detection range can be reduced. As a result, it is possible to reliably prevent detection of a human body in a state other than when garbage is actually put in.

  Furthermore, since the forcible release means of the locking means by the lid opening means is provided, in the case of a garbage disposal machine installed outdoors, it is not necessary for the user who carried the garbage to take it indoors again, Convenience can be improved.

  In the second garbage processing machine of the present invention, when the user approaches to throw in the garbage, the first human body detecting means detects the human body, and the lid is operated by operating the switch in this state. Open. Therefore, the lid can be reliably opened only when the user throws in the garbage. Further, when the user passes near the garbage disposal machine or when any object is located in the vicinity, the opening request by the switch is not made, so that the lid can be prevented from opening. Therefore, it is possible to prevent the user from being bothered and uncomfortable due to the smell.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

This garbage disposal machine accommodates a bio-base material in which bio-bacteria consisting of aerobic yeasts are carried on a base material such as sawdust, and performs processing by stirring the input raw garbage with the bio-base material. This is a bio system to be performed, and generally includes a processor main body 10 and a lid 32 that closes an upper portion of the processor main body 10 so as to be openable and closable.

  As shown in FIG. 1 and FIGS. 2A and 2B, the processor main body 10 includes a processing tank 11 that performs processing by putting raw garbage into the exterior body. A lock claw 12 is slidably disposed on the front upper portion of the processor main body 10 as a lock means for locking the lid 32 so that it cannot be opened. Further, the lock claw 12 has a lid opening means as a lid opening means. The drive motor 13 that unlocks the lid 32 by swinging the lock claw 12 and the hinge connection portion between the lid 32 and the opening direction. A spring (not shown) for urging the spring is arranged, and when the lock is released by the drive motor 13, the spring can be automatically opened by the urging force of the spring. Further, on the upper end surface of the processor main body 10, a switch 14 is disposed as a detecting means for detecting the closed state of the lid 32 by being pressed against the lower edge of the lid 32.

  Inside the processing tank 11, a stirring member 15 having a blade portion 15b protruding from a predetermined position of a shaft portion 15a extending in the width direction is rotatably installed as a stirring means. Both ends of the agitating member 15 pass through the treatment tank 11, and one end of the shaft portion 15a is connected to a motor 16 as a driving means by a belt 17 and pulleys 18A and 18B.

  A heater 19 is disposed on the lower outer peripheral surface of the treatment tank 11 as a heating means for heating the internal bio-base so as to be maintained within a predetermined temperature range. Further, the treatment tank 11 is provided with an exhaust duct 20 as an exhaust means for exhausting the air inside the apparatus to the outside of the apparatus so as to be located above the back portion, specifically, above the upper surface of the stored bio-base material. The fan 21 is disposed in the exhaust duct 20. In the exhaust duct 20, filters 22 </ b> A and 22 </ b> B are disposed at an opening facing the inside of the processing tank 11 and an opening facing the outside of the machine, respectively.

  In this embodiment, in order to automatically open the lid 32 by the drive motor 13 constituting the lid opening means, two detection means, a first human body detection sensor 23 and a second human body detection sensor 24, are used. Arranged in the processor main body 10. The lid 32 is provided with base material state detection means for detecting the state of the processing function based on the moisture content of the bio base material in the processing tank 11, and when the processing function by the bio base material is low, the drive motor 13, the lock claw 12 cannot be unlocked.

  Specifically, the first human body detection sensor 23 is an infrared sensor that detects whether or not the human body is approaching the vicinity by emitting infrared rays. The first human body detection sensor 23 is substantially horizontal at the upper center of the front surface of the processor main body 10. It is arranged to emit infrared rays in the direction.

  The second human body detection sensor 24 is composed of an IC element that can detect that a human body is approaching (presence / absence) by detecting a predetermined electrostatic capacity. It is arranged downward so that the floor surface is the detection range.

  The substrate state detection means includes three temperature sensors 25, 26, and 27 that detect the temperature Ts in the processing tank 11, the temperature Tk of the bio substrate, and the temperature Tg of the outside air. The processing tank temperature sensor 25 is disposed in the space temperature above the bio-base in the processing tank 11. The substrate temperature sensor 26 is disposed on the bottom in the processing tank 11. The outside air temperature sensor 27 is disposed on the exterior body of the processor main body 10.

  Further, in the present embodiment, as shown in FIGS. 1 and 3, a display panel 28 that is a display unit inclined upward is disposed on the front upper portion of the processor main body 10. The display panel 28 includes an ON / OFF switch 29 for operating or stopping the device, three display units 30a, 30b, and 30c indicating the state of the processing function by the bio-base material, and a filter cleaning display unit 31. I have. Among them, the display unit 30a is a good display showing that the processing function of the bio-base material is good, the display unit 30b is a secret display showing that the processing function is slightly lowered, and the display unit 30c is This is a stop display indicating that the processing function is degraded. The filter cleaning display unit 31 has an LED disposed in a switch.

  The lid 32 is attached to the processor main body 10 so as to be openable and closable, closes the charging opening 11 a of the processing tank 11, and is provided with a receiving portion 33 that engages with the lock claw 12.

  The garbage processing machine having the above-described configuration is operated according to a program set in advance by the microcomputer 34 as the control means. Specifically, as shown in FIG. 4, the microcomputer 34 operates when electric power from a commercial power source is applied with a DC voltage via a power supply circuit unit 35. Then, detection values (outside air Tg, in-tank Ts, base material Tk) detected by the temperature sensors 25, 26, and 27, which are base material state detection means, and a first threshold value Tα for turning on a preset heater 19; The second threshold value Tβ for turning off the heater 19, the first determination value X for determining that the moisture content of the bio-based material is excessive, and the second determination value Y for determining that the moisture content is low and dry. Based on this, as shown in FIG. 5, the heater 19 is turned on and off, and the rotation speed of the stirring member 15 is controlled. Further, the state of the processing function of the bio-base material is determined based on each detection value, and the state of the processing function of the bio-base material is displayed on the display panel 28.

  Furthermore, in this embodiment, when both the first and second human body detection sensors 23 and 24 detect a human body, the drive motor 13 which is a lid opening drive unit is operated to release the lock by the lock claw 12, While the lid body 32 is automatically opened by the hinge spring, when the bio-base processing function is low (stop determination), the lid body 32 cannot be automatically opened. Further, when the automatic opening is not performed, the state of adding garbage is notified by the sound output unit 36 such as a piezoelectric buzzer.

  Next, the control by the microcomputer 34 will be described in detail with reference to the control list shown in FIG. 5 and the control flow shown in FIGS.

  When the power is turned on, as shown in FIG. 6, the microcomputer 34 first detects whether or not the human body is approaching by the first human body detection sensor 23 in step S1. If it is detected that the human body is approaching, the process proceeds to step S2, and if it is not detected that the human body is approaching, the process proceeds to step S3.

  In step S2, it is detected by the second human body detection sensor 24 whether or not the human body is approaching. If it is detected that the human body is approaching, the process proceeds to step S5. If it is not detected that the human body is approaching, the process proceeds to step S3.

  In step S3, the temperatures Tg, Ts, Tk are detected by the temperature sensors 25, 26, and 27, which are substrate state detection means, and in step S4, a garbage disposal control process described later is executed, and the process returns to step S1. .

  If both human bodies are detected by the first and second human body detection sensors 23, 24, whether or not the processing function by the bio-base material is in a good state based on the determination in the garbage processing control process in step S3 in step S5. Detect whether or not. And when a bio-base material is favorable, it progresses to step S6, and when a bio-base material is not favorable (stopped state), it progresses to step S10.

  In step S6, after the stirring member 15 is rotated and then the stirring member 15 is stopped, in step S7, the drive motor 13 is operated to unlock the lid 32 by the lock claw 12. Thereby, the cover body 32 is automatically opened by the biasing force of the hinge spring.

  In step S8, the user waits until the lid 32 is closed by the user. That is, the user waits until the lid 14 is detected by the switch 14 which is a detecting means for detecting the closed state of the lid 32. If 32 is obstruct | occluded, in step S9, the stirring member 15 will be rotated and it will return to step S1.

  On the other hand, when it is determined in step S4 that the bio-base material is not good, in step S10, the addition addition notification is notified by the audio output unit 36, the locked state of the lid body 32 is continued, and the process returns to step S1.

  As described above, the garbage processing machine according to the present embodiment automatically opens the lid 32 when both the first human body detection sensor 23 attached to the upper part and the second human body detection sensor 24 attached to the lower part detect the human body. Therefore, the user can reliably throw in the garbage without touching the garbage processor. In addition, when the user passes the vicinity of the garbage disposal machine or when any object is located in the vicinity, the first human body detection sensor 23 and the second human body detection sensor 24 cannot detect the human body at the same time. Therefore, the lid 32 can be prevented from automatically opening. Therefore, it is possible to prevent the user from being bothered and uncomfortable due to the smell. Moreover, since the second human body detection sensor 24 uses a small detection range for detecting that the human body is approaching by detecting the electrostatic capacity, the state is excluded except when the garbage is actually put in. Therefore, the detection of the human body can be surely prevented.

  Next, the garbage processing control process of step S4 will be specifically described.

  In this garbage disposal control step, as shown in FIG. 7, first, in step S4-1, whether or not the detected outside air Tg is lower than the first threshold value Tα is compared, and the outside air Tg is the first threshold.

When the base material Tk is equal to or greater than the in-tank Ts, the process proceeds to step S4-11 shown in FIG.

  In step S4-6, it is detected whether or not the temperature obtained by subtracting the base material Tk from the in-tank Ts is higher than the first determination value X for determining that it is in an excessive water state (Ts−Tk> X). If the temperature difference is higher than the first determination value X, the process proceeds to step S4-7. If the temperature difference is equal to or less than the first determination value X, the process proceeds to step S4-8.

  In step S4-7, it is determined that the bio-base material is in an excessive water state, the bio-base material and garbage stirring operation by the stirring member 15 is increased (pattern (22) in FIG. 5), and the process returns. Since this determination state is a state in which the processing function of the bio-base material is deteriorated, the display unit 30c for stopping is lit on the display panel. In this case, in step S5, both the first and second human body detection sensors 23 and 24 detect the human body.

And when Ts in a tank is higher than outside air Tg, it progresses to Step S4-46, and when Ts in a tank is below outside air Tg, it progresses to Step S4-47.

  In step S4-46, it is determined that the treatment function by the bio-base material is slightly lowered, and after stirring until the temperature obtained by subtracting the in-tank Ts from the base material Tk is lower than the second determination value Y, the good state is obtained. Display (pattern (18) in FIG. 5) and return.

  In step S4-47, it is detected whether or not the base material Tk is higher than the outside air Tg (Tg <Tk). When the base material Tk is higher than the outside air Tg, the process proceeds to step S4-48, and when the outside air Tg is equal to or higher than the base material Tk, the process proceeds to step S4-49.

  In step S4-49, it is determined that the treatment function by the bio-base is slightly lowered, and after stirring until the Ts in the tank becomes higher than the outside air Tg, a good state is displayed (pattern (19) in FIG. 5). And return.

  In step S4-49, it is detected whether or not the base material Tk is lower than the outside air Tg (Tk <Tg). When the base material Tk is lower than the outside air Tg, the process proceeds to step S4-50. When the base material Tk is not lower than the outside air Tg, that is, when the base material Tk and the outside air Tg are the same (Tk = Tg). Proceed to step S4-51.

  In step S4-50, it is determined that the bio-base material is in a dry state, the stirring operation of the bio-base material and garbage by the stirring member 15 is suppressed (pattern (8) in FIG. 5), and the process returns.

  In step S4-51, it is determined that the bio-base material is in a good state, the stirring operation of the bio-base material and garbage by the stirring member 15 is normally stirred (pattern (20) in FIG. 5), and the process returns.

  On the other hand, if the detected base material Tk is greater than or equal to the second threshold value Tβ in step S4-26 shown in FIG. 10, the heater 19 is turned off in step S4-52, and then the biomaterial is detected in step S4-53. Although it is determined that the base material is in a good state, in order to lower the temperature of the bio base material, the bio base material and the garbage are stirred by the stirring member 15 (pattern (21) in FIG. 5) and returned. To do.

  In the present embodiment, since a bio-base material in which a bio-bacterium composed of aerobic yeast is supported on the base material is applied, the first threshold value Tα for turning on the heater 19 is about 20 ° C. The second threshold value Tβ for turning off the heater 19 is about 40 ° C. In addition, the first determination value X for determining that the moisture content of the bio-based material is excessive and the second determination value Y for determining that the moisture content is low and dry are “1”, respectively. Therefore, power consumption at the heater 19 can be reduced. Further, in the flowchart, an example of control of normal stirring, stirring increase, and stirring decrease of the stirring member 15 based on the determination of the state of the processing function of the bio-substrate is as shown in Table 1 below.

  As shown in Table 1, when it is determined that the condition is good and normal stirring control is performed, it is turned on (rotated) for 2 minutes based on a signal from the time measuring signal unit 37 and then turned off (stopped) for 23 minutes. . Further, when it is determined that the water content is excessive and the stirring is increased, it is turned on for 5 minutes and then turned off for 20 minutes. Furthermore, when it judges that it is drying and suppresses stirring, after turning on for 1 minute, it turns off for 24 minutes. In the present embodiment, the number of rotations per unit time is set to be the same, but the number of rotations may be changed instead of time.

  Thus, the garbage processing machine of this embodiment is provided with the temperature sensors 25, 26, and 27 for detecting the temperature inside the processing tank 11, the temperature of the bio-base material, and the temperature of the outside air, so that the garbage is decomposed. Therefore, the stirring member 15 and the heater 19 can be efficiently controlled. As a result, the decomposition process can be surely promoted.

  Moreover, it is possible to grasp the state of the processing function based on the moisture content of the bio-based material from the detection values of the temperature sensors 25, 26, and 27, and the state where the processing function is lowered (pattern (22) In (24)), the automatic opening of the lid 32 is impossible. Therefore, it is possible to ensure a usable period (durability) of the device including the bio-base material by excessively feeding raw garbage. In addition, the state in which the lock claw 12 cannot be unlocked is displayed on the display panel 28 and is notified by the audio output unit 36 to notify the user of the unusable state. It can prevent giving to a user.

  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, in the above-described embodiment, the lock claw 12 is provided as the locking means, and the lid 32 can be automatically opened by the hinge spring. However, a drive motor is provided at the hinge connection portion of the lid 32, and this drive is performed. The lid 32 may be opened and closed by the operation of the motor.

  Further, the first human body detection sensor 23 and the second human body detection sensor 24 are not limited to the infrared sensor and the IC element for detecting the electrostatic capacity, and both may be configured by the infrared sensor, and both may be the electrostatic capacity. You may comprise by the IC element which detects this.

  Furthermore, other sensors may be applied, and an opening / closing mechanism operated by a user with a foot may be applied as a human body detection means instead of the sensor. That is, it is possible to provide a lock means that cannot be operated in the pedal type opening / closing mechanism, and to release the lock means by detecting the human body by the first human body detection sensor 23 so that the lock means can be opened.

  Furthermore, the first human body detection sensor 23 and the display panel 28 are each disposed in the processor main body 10, but may be disposed on the lid 32.

  And in the said embodiment, even if the human body was detected by the 1st, 2nd human body detection means 23 and 24, when the processing function of the bio-base material was falling, it was made impossible to open the cover body 32. A means for forcibly releasing the lock claw 12 by the body opening means may be provided so that the user can forcibly open the lid 32 by his / her own judgment after knowing that the processing function is lowered. Specifically, as shown in FIG. 13, as the forcible release means, a switch 38 for forcible opening is provided on the display panel 28, and when the microcomputer 34 detects the operation of the switch 38, it is related to the state of the bio-base material. Instead, the lock 32 may be unlocked and the lid 32 may be opened. In this way, for example, in the case of a garbage disposal machine installed outdoors, it is not necessary for the user who brought the garbage to take it back indoors, so that convenience can be improved. Further, if the switch 38 is provided on a portion that is not normally used by the user, for example, on the bottom surface of the processor main body 10, the bio-substrate processing function is not inadvertently lowered. Note that this configuration can also be configured by a mechanical type using an operation unit that forcibly swings the lock claw 12 instead of the switch 38.

  Further, as shown in FIGS. 14A and 14B, instead of the second human body detection sensor 24, a lid opening switch 39 for making a request to open the lid 32 is provided on the display panel 28, and the microcomputer 34, when the first human body detection sensor 23 detects a human body and receives a request to open the lid body 32 by operating the lid body opening switch 39, the lock claw 12 locks the lid body 32. It is good also as a structure released and released.

  In this way, when the user approaches to throw in garbage, the first human body detection sensor 23 detects the human body, and in this state, the user operates the lid opening switch 39, so that the lid 32 is Open. Therefore, the lid 32 can be reliably opened only when the user throws in the garbage. Further, when the user passes near the garbage disposal machine or when any object is located in the vicinity, the opening request by the lid opening switch 39 is not made, and thus the lid 32 can be prevented from being opened. Therefore, similarly to the above-described embodiment, it is possible to prevent the user from being bothered by the unintentional opening of the lid 32 and discomfort due to odor.
