Description

  The present invention relates to a bio-type garbage processing machine that decomposes garbage input to a treatment tank by the activity of microorganisms that inhabit treatment materials.

  In recent years, reducing the amount of garbage generated every day in general households has become a social issue, and as a means for solving this problem, there are various garbage processing machines that mainly decompose garbage generated around the kitchen. Proposed. The garbage processing machine includes a crushing method for finely crushing garbage, a drying method for reducing the weight and volume by removing moisture from the garbage, and a bio-base on which aerobic biobacteria are supported on a substrate. There are three types of bio-methods that ferment and decompose raw garbage with wood.

  Among them, the bio type has a configuration in which an inlet is provided at the upper part of a processing tank in which a processing material such as porous wood chips and sawdust is accommodated, and stirring means is provided inside. Then, the garbage disposed in the treatment tank through the inlet is stirred together with the treatment material by the operation of the stirring means, and carbon dioxide gas and water are mixed with microorganisms (food fermentation bacteria, yeast, etc.) inhabiting the treatment material. It is disassembled.

  Such a garbage disposal machine needs to deodorize and exhaust the steam generated by heating, and there is the following as prior art document information in which a deodorizing heater is provided in the exhaust mechanism.

Japanese Patent Laid-Open No. 10-62067

  However, in order to deodorize exhaust with high efficiency by a deodorizing means such as a deodorizing heater, it is necessary to reduce the air volume of the exhaust mechanism. On the other hand, if the air volume is reduced, the amount of water that can be evaporated in the processing tank is reduced, so it is necessary to turn on the heating means of the processing tank and increase the amount of water that can be evaporated. As a result, there is a problem that the power consumption of the whole garbage disposal machine becomes high. Moreover, when the heating amount by a heating means is made high, it will become higher than the temperature suitable for the inhabiting of the microorganism which inhabited the processing material, and there exists a problem that the decomposition ability of garbage is reduced by reducing the activation of microorganisms.

  The present invention has been made in view of the conventional problems, and provides a garbage processing machine that can efficiently deodorize and exhaust without lowering the decomposition ability and can reduce power consumption. Is an issue.

  In order to solve the above-mentioned problems, a garbage processing machine according to the present invention includes a processing tank for storing a processing material, heating means for heating the processing tank so as to maintain the inside of the processing tank in a predetermined temperature range, In a garbage disposal machine comprising an exhaust means for exhausting air, and a deodorization means for deodorizing odor contained in the exhaust gas by the exhaust means, wherein the garbage thrown into the treatment tank is decomposed by a treatment material, The heating means includes a first heating unit positioned at the lower part of the processing tank and a second heating unit positioned at the upper part of the processing tank, each configured to be individually controllable to heat, Detection means for detecting the moisture content of the treatment material is provided, and the heating amount by the second heating means is adjusted based on the moisture content of the treatment material based on the detection value of the detection means.

  According to this garbage processing machine, since the second heating unit is controlled independently of the first heating unit, it hardly affects the temperature control of the processing material and inhabits the processing material. Decreasing the activity of microorganisms can be prevented. In addition, since the heating amount of the second heating unit is adjusted based on the moisture content of the treatment material detected by the detection unit, energy saving related to the heating by the first heating unit and the deodorizing unit can be achieved. Specifically, since the cold outside air entering along with the exhaust control by the exhaust means can be heated to raise the temperature, the temperature of the treatment material can be prevented from being lowered by the outside air, and energy saving of the first heating unit can be achieved accordingly. Further, since the exhaust gas passing through the deodorizing means is preheated by the second heating unit, the temperature drop in the deodorizing means can be minimized, and energy saving can be achieved correspondingly.

  In this garbage disposal machine, when the water content of the treatment material detected by the water content detection means is large, it is preferable to suppress the exhaust amount by the exhaust means. In this way, since the amount of exhaust air passing through the deodorizing means is suppressed, a sufficient reaction time for deodorization can be secured and a sufficient deodorizing action can be obtained.

  Moreover, when the moisture content of the processing material detected by the moisture content detecting means is large, it is preferable to increase the heating amount by the second heating unit. In this way, it is possible to compensate for the release of moisture from the treatment material in the treatment tank, so that appropriate humidity can be promoted. In particular, this configuration is effective in a situation where the exhaust amount by the exhaust means is suppressed.

  In the garbage processing machine of the present invention, since the second heating unit is controlled independently of the first heating unit, the temperature of the processing material is hardly affected. In addition, since the heating amount of the second heating unit is adjusted based on the moisture content of the treatment material detected by the detection unit, energy saving related to the heating by the first heating unit and the deodorizing unit can be achieved. In addition, the release of moisture contained in the treatment material can be reliably adjusted, the activation of microorganisms living in the treatment material can be promoted, and as a result, the decomposition efficiency of garbage can be improved.

The deodorizing switch 51 is provided with LEDs indicating an operating state (lighted) and a stopped state (extinguished) in the switch.

  The lid body 52 is rotatably attached to the upper surface of the lid frame 14 of the processor main body 10 and is urged in the opening direction by a hinge spring 53 which is an urging means. A pressing member 54 that protrudes downward in an arc shape is provided in the vicinity of the hinge connecting portion, and the opening and closing states of the lid 52 can be detected by turning on and off the switch 55 by the pressing member 54. is doing. Further, as shown in FIG. 1, a locking receiving portion 56 that protrudes downward is provided at the front portion of the lid body 52, and the locking receiving portion 56 is locked and unlocked by a locking means 57. The locking means 57 includes a rotatable locking member that locks the locking receiving portion 56 and a solenoid that operates the locking member.

  As shown in FIGS. 1 and 5, the garbage processing machine configured as described above has a first temperature sensor as a temperature detecting means for detecting the temperature of the processing material in the processing material accommodation area in the processing tank 22. 58 is disposed, and a second temperature sensor 59 is disposed outside the processing tank 22. Then, the temperature difference between the inside and outside is calculated based on the detected values of the temperature sensors 58 and 59, and a correction value set in advance based on the temperature difference is added to the detected temperature based on the detected value of the first temperature sensor 58. The temperature of the processing material set in advance is controlled.

  In addition, a pair of electrodes 60 a and 60 b are disposed so as to be located inside the treatment tank 22 as moisture detection means for detecting the moisture content of the treatment material. These electrodes 60a and 60b are arranged so as to be opposed to each other in plan view of the processing tank 22 and to be positioned at a predetermined interval in the vertical direction. And it is set as the structure which can detect the moisture content of a processing material by applying a predetermined voltage from the voltage application circuit which is not shown in figure, and a current flowing through a processing material as a conductor. Specifically, the magnitude of the current passed through the treatment material is proportional to the resistance value made of the treatment material, and this resistance value is substantially proportional to the amount of moisture contained in the treatment material. Therefore, the electrodes 60a and 60b can be used as a moisture sensor that correctly detects the moisture content in the treatment material by taking out the output of a bridge circuit in which the electrode 60a and 60b are incorporated as one resistor, for example.

  As shown in FIG. 1, a driving motor 25, planar heaters 37 and 38, blower fans 40 and 41, a driving circuit for the catalyst heater 45, and an electrode 60a are provided in the lower front portion between the outer package 11 and the processing tank 22. , 60b, and a control board 61 on which peripheral circuits such as temperature sensors 58 and 59 and a thermistor are mounted and connected. And the microcomputer 62 which is a control means mounted in this control board 61 is operate | moved according to the program set beforehand. Specifically, the microcomputer 62 operates by converting electric power from a commercial power source into a DC voltage by the power supply circuit unit 63 and applying the DC voltage. The operating state of each component is input to the microcomputer 62 from a built-in sensor or an attached sensor.

  Then, it functions as a lid opening means, and when the distance measuring sensor 46 detects that an object including a human body is close to a detectable range, the locking means 57 is operated to engage the locking receiving portion 56. By releasing the stop, the lid body 52 is automatically opened by the biasing force of the hinge spring 53. At this time, if the stirring member is operating (rotating), the lid member 52 is opened after the stirring member 24 is stopped. If the stirring member 24 is not operating, the opening process is performed as it is. .

  When the switch 52 detects that the lid 52 is closed, the time measurement is started by the built-in time timer 64 with the closed time as the control start point, and the rotation of the stirring member 24, the planar heater 37, 38, the blower fans 40, 41, and the on / off control of the catalyst heater 45 are started. Thus, the microorganisms carried on the treatment material are always brought into contact with fresh air in an appropriate temperature and humidity state to promote activation.

  In addition, the state of the treatment function (moisture content) of the treatment material is determined based on the detection values of the electrodes 60a and 60b every predetermined time (for example, 2 hours), and the control of each component is adjusted based on the determination result. The information is displayed on the display unit 50 of the operation panel 48. Here, the conditions for the active activity of the microorganisms carried on the treatment material are a temperature of about 20 to 40 ° C. and a moisture content of about 30 to 45%. Therefore, each component is controlled based on the detected temperature by the temperature sensors 58 and 59 and the detected humidity by the electrodes 60a and 60b so as to maintain these ranges. Moreover, the state of the treatment material to be judged is that the moisture content is an appropriate amount of 30% or more and 45% or less, that the moisture content is less than 30%, and that the moisture content is more than 45%. It is a sticky state.

  Next, the garbage disposal control process by the microcomputer 62 will be specifically described.

  In this garbage disposal control process, as shown in FIG. 6, the microcomputer 62 first determines whether or not a request to open the lid 52 is detected via the distance measuring sensor 46 in step S <b> 1. If an opening request is detected, the process proceeds to step S2. If an opening request is not detected, the process proceeds to step S6. When the automatic opening mechanism of the lid body 52 by the distance measuring sensor 46 and the lock means 57 is not mounted, the opening of the lid body 52 is detected by the switch 55.

  In step S2, after stopping the driving components such as the agitating member 24, the planar heaters 37 and 38, and the blower fans 40 and 41, the locking means 57 is operated to open the lid 52 in step S3. Do. Next, in step S4, the process waits until it is detected that the lid body 52 is closed via the switch 55. When the closure of the lid body 52 is detected, in step S5, a processing function based on the water content of the treatment material or the like. The detection period timer (for example, 2 hours) that measures the period for detecting the state of the above is reset and started, and the process proceeds to step S6.

  In step S6, it is detected whether or not the detection cycle timer timer has counted up. If the count is up, the process proceeds to step S7. If the count is not up, the process proceeds to step S9.

  In step S7, the detection cycle timer is reset and started to detect the state of the processing function of the processing material next, and then in step S8, the processing material state detection processing by the temperature sensors 58 and 59 and the electrodes 60a and 60b. To proceed to step S9.

  In step S9, the stirring means control process including the drive motor 25 and the stirring member 24, the heating means control process by the first planar heater 37, the display means changing process of the operation panel 48 for displaying the state of the processing material, and the second A processing material adjustment process including an exhaust control process by the planar heater 38, the blower fans 40 and 41, and the deodorizing means is executed, and the process returns to step S1. Note that each processing in the processing material adjustment processing is executed in parallel.

  Here, immediately after the user throws in the garbage, the process goes to step S9 through steps S1 to S6. Immediately after the raw garbage is input, the amount of input of the raw garbage at that time is unknown, so that it is impossible to predict an increase in moisture and a decrease in temperature. Therefore, in the present embodiment, when the treatment material adjustment process is performed immediately after detecting the blockage of the lid body 52, which means immediately after charging, it is the same as in the case of a good temperature and humidity condition (water content 40%, temperature 30 ° C.). Execute the control.

  Among them, the agitation means control processing is performed so as to repeat a preset stop time and a period for stopping the agitation member 24 after operating the agitation member 24 for a preset operation time. In this embodiment, one cycle is set to 7 minutes, and the operation time is 60 seconds when the processing material is in a good state, 48 seconds when the processing material is in a dry state, and a sticky state. Is set to repeat the period for 72 seconds until the next detection period.

  The heating means control process repeats a cycle for turning off the first planar heater 37 for a preset stop time after turning on the first planar heater 37 for a preset operation time, similarly to the stirring member 24. To control. In this embodiment, one cycle is set to 7 minutes, and the operation time is 3 minutes when the processing material is in a good state, 1 minute when the processing material is in a dry state, and a sticky state. Is set to repeat the period of operation for 5 minutes until the next detection period. However, you may change the heating amount by the 1st planar heater 37 instead of time.

  As described above, the display means changing process turns on the display unit 50 of the operation panel 48 based on the moisture content (amount) of the treatment material detected by the treatment material detection process.

  In the exhaust control process, after operating the preset operation time, the blower fan and the catalyst heater 45 of the deodorizing means, the preset stop time, the second planar heater 38, the blower fans 40, 41, and the catalyst heater 45 are set. The control is performed so as to repeat the control cycle. In this embodiment, one cycle is set to 7 minutes, and the operation time is 3 minutes when the processing material is in a good state, 0 minutes when the processing material is in a dry state, and a sticky state. For 6 minutes. In addition, the second planar heater 38, the blower fans 40 and 41, and the catalyst heater 45 perform different control based on the detected humidity of the processing material and select whether or not to operate the deodorizing function by the deodorizing switch 51. Different control is performed depending on the state.

  Specifically, as shown in FIG. 7, the second planar heater 38 is controlled based only on humidity regardless of whether or not the deodorizing function is used together. That is, when the humidity is less than 30%, the operation is stopped. Moreover, when it is in a good state of 30% or more and 45% or less, it is operated during the operation time with a heating amount (energization rate) of 50%. Further, when the sticky state is higher than 45%, it is operated during the operation time with a heating amount of 100%. The control of the second planar heater 38 may change the operation time instead of the heating amount.

  Further, as described above, the blower fans 40 and 41 are controlled based on the detected humidity and whether or not the deodorizing function is used in combination. That is, when the humidity is less than 30%, both the blower fans 40 and 41 are stopped regardless of whether the deodorizing function is used or not. Further, in a good state of 30% or more and 45% or less, whether or not the deodorizing function is used together, the first blower fan 40 is operated during the operation time, and the second blower fan 41 is stopped. Is done. Further, when the sticking state is higher than 45%, the first blower fan 40 is operated during the operation time regardless of whether or not the deodorizing function is used together, and the second blower fan 41 uses the deodorizing function together. In some cases, it is stopped and when it is not used together, it is operated for the operation time.

  Further, when the deodorizing function is turned off by the operation of the deodorizing switch 51, the catalyst heater 45 is stopped regardless of the detected humidity. Moreover, when the deodorizing function is turned on, it is stopped when the humidity is in a dry state of less than 30%. Further, when it is in a good state of 30% or more and 45% or less, it is operated during the operation time. Furthermore, when it is in a sticky state higher than 45%, it is operated during the operation time.

  And the processing material with which the inside of the processing tank 22 was filled by the control of these stirring members 24, the planar heaters 37 and 38, and the ventilation fans 40 and 41 is adjusted to the preset suitable temperature and humidity. As a result, the activity of microorganisms that inhabit the treatment material is enhanced, and it becomes possible to improve the decomposition efficiency of garbage. Further, by controlling the second planar heater 38, the blower fans 40 and 41, and the catalyst heater 45, the air in the treatment tank 22 is efficiently deodorized and exhausted without affecting the habitat environment of microorganisms of the treatment material. it can.

  Specifically, the processing member acts so as to be lifted upward by the rotation of the stirring member 24, and ventilation and moisture release inside the processing member are effectively promoted. Further, the treatment material is heated to an appropriate temperature by the heating by the first planar heater 37 and acts to vaporize the contained water. Furthermore, evaporation of moisture contained in the processing material is promoted by heating the air above the processing tank 22 by the second planar heater 38. And by the operation | movement of the 2nd ventilation fan 41, while fresh air is supplied to the processing material surface in the processing tank 22, the operation | movement of the 1st ventilation fan 40 changes the air in the processing tank 22 containing an odor and a water | moisture content. By exhausting efficiently to the outside, appropriate humidity is promoted.

  On the other hand, when the deodorizing function is on, in the sticky state where the odor is extremely high, the first blower fan 40 is operated, the second blower fan 41 is stopped, and the catalyst heater 45 is operated. Thereby, by heating the catalyst 43 to about 300 ° C., the air volume (wind speed) is too large in spite of being in a sufficiently deodorizable state, so that the reaction time for deodorization cannot be sufficiently secured, It is possible to prevent air from being discharged in an insufficient deodorizing state. Conversely, when the deodorizing function is off, both the blower fans 40 and 41 are operated, and the catalyst heater 45 is stopped. Thereby, although deodorization of air is not carried out of course, since the dry external air can fully be given to the surface of a processing material, discharge | release of the water | moisture content which a processing material contains can be accelerated | stimulated and appropriate humidity can be promoted. As described above, the exhaust amount of the exhaust means including the pair of blower fans 40 and 41 is adjusted based on the necessity of using the deodorizing function by the user and the humidity of the processing material. In addition, the moisture of the treatment material can be improved.

  In addition, since the second planar heater 38 is controlled independently of the first planar heater 37, the temperature control of the processing material is hardly affected. Further, the second planar heater 38 adjusts the heating amount (temperature) by the second planar heater 38 based on the moisture content of the treatment material detected by the electrodes 60a and 60b, and therefore the first planar heater 37 and the catalyst. Energy saving related to the heating by the heater 45 can be achieved, and the release of moisture contained in the treatment material can be reliably adjusted.

  Specifically, in the exhaust control process, even if the operation of the second blower fan 41 is stopped, the first blower fan 40 is operated, so that the pressure difference between the inside and outside of the treatment tank 22 causes the air supply port 18 to Cold external air will be introduced. However, since the air is heated by the second planar heater 38, it is possible to prevent the surface temperature of the treatment material from being lowered. As a result, it is possible to prevent the activity of microorganisms living in the treatment material from being reduced, and to prevent an increase in the amount of heat (time) by the first planar heater 37, thereby saving energy accordingly.

  Further, the temperature of the catalyst 43 is adjusted to about 300 ° C. by the catalyst heater 45, but the exhaust gas passing through the catalyst 43 is preheated by the second planar heater 38, so that the temperature drop of the catalyst heater 45 is minimized. The amount of heating by the catalyst heater 45 can be prevented, and energy can be saved accordingly.

  Furthermore, if the air volume is reduced in the exhaust control process, the amount of water released from the processing tank 22 is reduced. However, by raising the temperature of the upper part of the processing tank 22 by the second planar heater 38, the moisture is discharged from the processing tank 22. The amount of moisture to be made can be supplemented.

  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 first blower fan 40 is operated to stop the second blower fan 41 in order to suppress the exhaust air volume in the good state and the sticky state, but the second blower fan 41 is operated. The first blower fan 40 may be stopped. Of course, each blower fan 40, 41 may be one that can adjust the rotational speed stepwise, and the exhaust amount may be adjusted by adjusting the rotational speed of both the blower fans 40, 41.

  In the above embodiment, in the exhaust control process, the first blower fan 40 is operated in a good (appropriate humidity) state where the humidity is 30% or more and 45% or less. It is good also as a structure which temperature-controls the upper part of 22 to the temperature which does not have trouble in about 70 degreeC safety | security, and stops both the ventilation fans 40 and 41. FIG. In this way, the air in the processing tank 22 is supplied from the air supply port 18 due to the temperature difference between the inside and the outside and exhausted through the exhaust duct 39. Then, deodorizing and exhausting can be performed while the catalyst 43 ensures a sufficient deodorizing reaction time during the exhaust. In addition, power consumption in the catalyst heater 45 can be further suppressed, and energy saving can be achieved.

  Furthermore, in the above-described embodiment, the heating means and the exhaust control configuration of the present invention are applied to a bio-type garbage processing machine that promotes the decomposition process by stirring the processing material and the garbage with the stirring member 24 that is the stirring means. Although applied, the same operation and effect can be obtained even if the present invention is applied to a drying-type garbage processing machine that reduces the weight and capacity by removing moisture from the garbage only by the heating means.
