Description

  The present invention relates to a bio-type garbage disposal machine mainly used at home.

  This type of garbage processing machine is one that ferments and decomposes garbage with a treatment material in which an aerobic microorganism (bio fungus) is supported on a base material. In this garbage processing machine, in order to ensure a temperature environment suitable for the inhabiting of microorganisms, it is necessary to give a heat amount so as to maintain the processing material in an appropriate temperature range. However, there is a problem that the heat source for generating such an amount of heat consumes a large amount of energy.

  Prior art document information related to the garbage processing machine of the present invention includes the following.

Japanese Patent Laid-Open No. 11-188340

  In Patent Document 1, the heat of warm exhaust gas from the processing tank is transferred to the inside of the processing tank and the supply air via a heat exchanger. Thus, the heat energy released to the outside along with the exhaust gas is reduced to reduce the power consumed by the heat source for heating.

  However, in this garbage processing machine, there is a problem that the heating efficiency is remarkably poor because the air supply is heated by the heat exchanger with the space between the exterior body and the processing tank as the air supply passage. . In addition, since the environment suitable for the inhabiting of microorganisms is greatly related not only to the temperature condition but also to the humidity condition, there is a drawback that the humidity in the treatment tank falls below an appropriate range when the outside air is taken in as it is.

  The present invention has been made in view of the conventional problems, and improves the thermal energy efficiency by transmitting the heat of the exhaust to the supply air, and also improves the processing efficiency by transmitting the latent heat of the exhaust to the supply air. It is an object to provide a waste disposal machine.

  In order to solve the above-mentioned problems, the garbage processing machine of the present invention includes a processing tank for storing a processing material, and heating means for heating the processing material so as to maintain the processing material in a predetermined temperature range. In the garbage processing machine that decomposes the input garbage with a processing material, the supply tank and the exhaust pipe are piped in the processing tank, and at least a part of these pipes are arranged so as to intersect or contact each other. It is set as the structure which installed the heat exchanger in the part.

Therefore, the energy consumption of the heat source that heats the inside of the treatment tank can be reduced.

  In this garbage processing machine, it is preferable that a single air blowing means is disposed in the air supply line or the exhaust line. As described above, in the configuration in which the air supply pipe and the exhaust pipe are provided in the upper part of the processing tank, the air supply to the inside of the processing tank and the exhaust to the outside can be reliably performed only by disposing the air blowing means on one of them. This can be done and the cost can be reduced.

  Moreover, it is preferable that the said heat exchanger consists of a total heat exchanger with which the partition plate which partitions off an air supply pipe line and an exhaust pipe line has moisture permeability. In this way, not only the sensible heat but also the latent heat can be exchanged between the supply air and the exhaust gas, so that the water content (humidity) of the treatment material in the treatment tank can be kept appropriate. As a result, it is possible to reliably improve the processing efficiency of garbage by the processing material.

Furthermore, it is preferable to provide a second air supply line for supplying air into the processing tank.
In this case, detection means for detecting the water content of the treatment material in the treatment tank is provided, and the air supply means of the second air supply line is controlled based on the water content of the treatment material based on the detection value of the detection means. Is preferred.
In this manner, in the garbage processing machine having excellent heat retention and moisture retention, when the water content of the processing material exceeds the appropriate humidity due to the introduction of new garbage, efficient ventilation can be performed.

  In the garbage processing machine according to the present invention, the heat exchanger is disposed at a part where the air supply line and the exhaust line intersect or contact each other, so that the heat exchange between the exhaust and the air can be efficiently performed. The energy consumption of the heat source for heating the inside of the treatment tank can be reduced. In addition, the heat exchanger is composed of a moisture permeable total heat exchanger that can exchange the latent heat of the supply air and exhaust gas, so that the water content (humidity) of the treatment material in the treatment tank is maintained appropriately.

  The lid 63 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 64 as urging means. A pressing member 65 projecting downward in an arc shape is provided in the vicinity of the hinge connection portion, and the opening and closing states of the lid 63 can be detected by turning on and off the switch 66 by the pressing member 65. is doing. Further, as shown in FIG. 1, a locking receiving portion 67 protruding downward is provided at the front portion of the lid 63, and the locking receiving portion 67 is locked and unlocked by the locking means 68. The locking means 68 includes a rotatable locking member that locks the locking receiving portion 67 and a solenoid that operates the locking member. It should be noted that detecting that the switch 66 has changed from the open state to the closed state means that the user has thrown in the garbage and closed the lid 63, so the switch 66 enters the processing material. It also serves as a means for detecting the input of raw garbage.

  As shown in FIGS. 1 and 7, the garbage processing machine configured as described above has a first temperature sensor as a temperature detection means for detecting the temperature of the treatment material in the treatment material accommodation area in the treatment tank 22. 69 is disposed, and a second temperature sensor 70 is disposed outside the processing tank 22. The temperature determination of the processing material by these temperature sensors 69 and 70 is performed by calculating a temperature difference based on the detected value and adding a correction value preset based on the temperature difference to the detected temperature based on the detected value of the first temperature sensor 69. By doing.

  In addition, a pair of electrodes 71 a and 71 b are disposed as moisture detection means for detecting the water content of the treatment material so as to be located inside the treatment tank 22. These electrodes 71a and 71b are arranged so as to be opposed to each other in plan view of the processing tank 22 and 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 71a and 71b can be used as a moisture sensor that correctly detects the moisture content in the processing material by taking out the output of a bridge circuit in which the electrode 71a and 71b are incorporated as one resistor, for example.

  As shown in FIG. 1, a driving motor 25, a planar heater 37, a blower fan 53, a compression pump 58, a heating heater 55, and a heating unit 59 are driven at a lower front portion between the exterior body 11 and the processing tank 22. A circuit board, a voltage application circuit to the electrodes 71a and 71b, and a control board 72 on which peripheral circuits such as temperature sensors 69 and 70 and a thermistor are mounted and connected are arranged. And the microcomputer 73 which is a control means mounted in this control board 72 is operate | moved according to the program set beforehand. Specifically, the microcomputer 73 operates by converting electric power from a commercial power source into a DC voltage by the power supply circuit unit 74 and applying the DC voltage. The operating state of each component is input to the microcomputer 73 from a built-in sensor or an attached sensor.

  Then, it functions as a lid opening means, and when the distance measuring sensor 38 detects that an object including a human body has come within a detectable range, the locking means 68 is operated to engage the locking receiving portion 67. By releasing the stop, the lid 63 is automatically opened by the biasing force of the hinge spring 64. At this time, when the stirring member is operating (rotating), the lid 63 is opened after stopping the operation of the stirring member 24, and when the stirring member 24 is not operating, the opening process is performed as it is. .

  When the switch 66 detects that the lid body 63 is closed, the time measurement is started by the built-in time counting timer 75 using the closed time as a control start point, and the rotation of the stirring member 24, the planar heater is started. ON / OFF, and on / off control of the blower fan 53 and the compression pump 58 is 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. Specifically, the conditions for the active microbes carried on the treatment material are that the temperature is about 20 to 60 ° C. and the moisture content is about 40 to 60%, and is always in contact with fresh air. It is necessary to do. Therefore, each component is controlled based on the detected temperature by the temperature sensors 69 and 70 and the detected humidity by the electrodes 71a and 71b so as to maintain these ranges.

  In addition, the state of the treatment function (moisture content) of the treatment material is determined based on the detection values by the electrodes 71a and 71b every predetermined time, and the determination result is displayed on the display unit of the operation panel 76. Here, the state of the treatment material to be judged is that the moisture content is an appropriate amount of 40% or more and 60% or less, that the moisture content is less than 40%, and that the moisture content is more than 60%. It is sticky to stop. In addition, you may perform the state judgment of a processing material combining the moisture content by the electrodes 71a and 71b, and the detected value of the temperature sensors 69 and 70. FIG.

  Next, the garbage processing control process by the microcomputer 73 will be specifically described.

  In this garbage disposal control process, as shown in FIG. 8, the microcomputer 73 first determines whether or not a request to open the lid 63 is detected via the distance measuring sensor 38 in step S1. 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 for the lid 63 by the distance measuring sensor 38 and the lock means 68 is not mounted, the opening of the lid 63 is detected by the switch 66.

  In step S2, after stopping the driving components such as the stirring member 24, the planar heater 37, the blower fan 53, and the compression pump, the locking unit 68 is operated to open the lid 63 in step S3. . Next, in step S4, the process waits until it is detected that the lid 63 is closed via the switch 66, and when the closure of the lid 63 is detected, in step S5, a processing function based on the moisture content of the processing material, etc. The detection period timer (7 minutes) for measuring the period for detecting the state of the above is reset and started, and the process proceeds to step S6. The time of the detection cycle timer can be changed as desired.

  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 69 and 70 and the electrodes 71a and 71b. 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 using the planar heater 37, the supply / exhaust means control process using the blower fan 53 and the deodorizing means, the supply by the compression pump 58 and the heating unit 59 are performed. A processing material adjustment process including an air means control process and a display means changing process of the operation panel 76 for displaying the state of the processing material 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 63, which means immediately after charging, it is the same as in the case of a good temperature and humidity condition (water content 50%, temperature 40 ° 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 the present embodiment, out of 7 minutes of the detection cycle, the operation time is 60 seconds when the treatment material is in a good state, 48 seconds when the treatment material is dry, and 48 hours when the treatment material is dry. Is set to operate for 72 seconds.

  In the heating means control process, similar to the stirring member 24, after the preset operation time and the planar heater 37 are turned on, the preset stop time and the cycle of turning off the planar heater 37 are controlled to be repeated. It is. In this embodiment, out of 7 minutes of the detection cycle, the operation time is 3 minutes when the treatment material is in a good state, 1 minute when the treatment material is in a dry state, and when it is in a sticky state. Is set to operate for 5 minutes. However, the heating amount by the planar heater 37 may be changed instead of the time.

  In the air supply / exhaust means control processing, after operating the air blower fan 53 and the heater 55 of the deodorizing means in conjunction with the preset operation time, the air supply fan / exhaust means control process is stopped in conjunction with the airflow fan 53 and the deodorizing means set in advance. It is controlled to repeat the cycle. In this embodiment, as shown in FIG. 9, out of 7 minutes of the detection cycle, the operation time is 5 minutes when the treatment material is in a good state and 2 minutes when the treatment material is in a dry state. When it is in a sticky state, it is operated for 7 minutes.

  As shown in FIG. 10, the air supply means control process controls the compression pump 58 based on the detection values by the electrodes 71a and 71b, and heats based on the detection values inside and outside the processing tank 22 by the temperature sensors 69 and 70. The unit 59 is controlled, and the operation time is synchronized with the control of the stirring member 24.

  Specifically, the compression pump 58 is stopped when the moisture content is less than 40%, and is weakly operated so as to supply a small amount of air when the moisture content is 40% or more and 50% or less. When it is higher and 60% or less, it is operated while the supply amount is higher than that of the weak operation, and when it is higher than 60%, it is operated more strongly than the intermediate operation.

  Further, the heater of the heating unit 59 is operated in an off state when the temperature of the treatment material determined by the detection values of the temperature sensors 69 and 70 is less than 20 ° C. and the moisture content is less than 40%, When it is 40% or more and 50% or less, it is operated with a heating amount of 50%, when it is higher than 50% and 60% or less, it is operated with a heating amount of 100%, and when it is higher than 60%, it is 100. % Of heating. Further, when the temperature of the treatment material is 20 ° C. or more and 40 ° C. or less and the water content is less than 40%, the treatment material is operated in an off state, and when the treatment material is 40% or more and 50% or less, 50%. When it is higher than 50% and 60% or less, it is operated with a heating amount of 100%, and when it is higher than 60%, it is operated with a heating amount of 100%. Further, when the temperature of the treatment material is higher than 40 ° C. and lower than or equal to 60 ° C. and the moisture content is lower than 40%, it is operated in an off state, and when it is 40% or higher and 50% or lower, it is 50%. When it is higher than 50% and 60% or less, it is operated with a heating amount of 100%, and when it is higher than 60%, it is operated with a heating amount of 100%. Further, when the temperature of the treatment material is higher than 60 ° C. and the moisture content is less than 40%, it is operated in an off state, and when it is 40% or more and 50% or less, the heating amount is 50%. It is operated with a heating amount of 100% when it is higher than 50% and below 60%, and it is operated with a heating amount of 100% when it is higher than 60%. As described above, in the present embodiment, the heating unit 59 is controlled only in accordance with the humidity regardless of the temperature of the treatment material. However, the heating amount can be further finely adjusted based on the temperature and the humidity.

  As described above, the display means changing process is to turn on the display unit of the operation panel 76 based on the moisture content (amount) of the treatment material detected by the treatment material detection process.

  By the control of the compression pump 58 including the stirring member 24, the planar heater 37, the blower fan 53, and the heating unit 59, the processing material filled in the processing tank 22 is adjusted to a preset appropriate temperature and humidity and is always fresh. Air (oxygen) is supplied in an appropriate amount. 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.

  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 planar heater 37 and acts to vaporize the contained water. Further, the operation of the blower fan 53 supplies fresh air to the surface of the treatment material in the treatment tank 22 and also efficiently exhausts the existing air in the treatment tank 22 containing moisture to the outside, so that the appropriate humidity is obtained. Is promoted. Then, the supply of air by the compression pump 58 promotes the release of gas and water vapor in the treatment material, and the activity is promoted by supplying fresh air (oxygen) to the inhabiting microorganisms. Moreover, the heating of the treatment material is promoted by the heating of the supplied air by the heating unit 59, and the appropriate humidity is also promoted.

  Here, in this embodiment, since air (oxygen) from the air introduction pipe 61 is supplied into the treatment material at the lower part of the treatment tank 22, the air circulates through the gap between the treatment materials to the upper part of the treatment material. After that, the air is exhausted (ventilated) together with the carbon dioxide gas and moisture generated by the decomposition by the blower fan 53. In addition, since oxygen can be efficiently supplied to the treatment material, the activity of microorganisms that inhabit the treatment material can be increased, and the decomposition process of garbage can be made efficient. Furthermore, electrodes 71a and 71b are provided as detection means for detecting the moisture content of the treatment material, and the compression pump 58 is turned on and off based on the moisture content based on the detected value, and the air supply amount is also adjusted. An appropriate amount of air can be supplied when oxygen is required, and the treatment material can always be kept in an appropriate state.

  Moreover, since the heating section 59 for heating the air supplied into the processing tank 22 is provided in the air introduction pipe 61 so that hot air can be supplied to the processing material, particularly immediately after new garbage is introduced. When the moisture content exceeds the appropriate humidity, the moisture removal time contained in the treatment material can be shortened, the microorganisms can be further activated, and the treatment efficiency can be further improved. And by the synergistic action of such an appropriate amount of air supply and the heating of the planar heater 37 and the heating unit 59, the activity of microorganisms living in the treatment material can be increased as much as possible, and the garbage is decomposed. Can be performed with high efficiency.

  On the other hand, when the blower fan 53 as the air supply / exhaust means is operated, the temperature of the outside air supplied into the processing tank 22 is lower than the temperature of the air in the processing tank 22, so Decreases and the energy consumption of the planar heater 37 increases. However, in the present embodiment, the supply pipe 44 and the exhaust pipe 45 are crossed, the two pipes 44 and 45 are partitioned at that portion, and heat exchangeable so as to balance the supply and exhaust temperatures. An exchanger 48 is provided. Therefore, in order to promote the activation of microorganisms, it is possible to prevent the temperature of the treatment material from being extremely lowered for the purpose of supplying fresh air to the upper surface of the treatment material. In addition, in the present embodiment, the exhaust pipe 45 is provided with deodorizing means. Therefore, the temperature of the exhaust gas is raised from the temperature in the processing tank 22 by heating by the heater 55. As a result, the supply air can be heated to a temperature substantially equal to the temperature at the time of exhaust by a heat exchange action, and wasteful energy consumption in the planar heater 37 can be greatly reduced.

  Moreover, although the moisture content suitable for the activity of microorganisms is also required, even if the humidity inside the treatment tank 22 is suitable, if there is a difference between the humidity of the outside air and the humidity inside the treatment tank 22, The moisture content deviates from its suitable humidity range. However, in the present embodiment, since the heat exchanger 48 is constituted by a total heat exchanger that can exchange not only sensible heat but also latent heat, moisture in the exhaust gas can be transmitted to the supply air. As a result, the water content (humidity) of the treatment material in the treatment tank 22 can be maintained appropriately, and the processing efficiency of the garbage with the treatment material can be reliably 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.
