Description

  The present invention relates to a garbage disposal machine that decomposes garbage introduced into a treatment tank by the activity of microorganisms that inhabit treatment materials.

  Household garbage processing machines include a crushing system that finely crushes garbage, a drying system that reduces weight and volume by eliminating moisture in the garbage, and an aerobic microorganism (bio fungus) as a base material. There are three types of bio-types that ferment and decompose raw garbage with a loaded treatment material.

  Among them, a bio-type garbage processing machine is provided with a rotatable stirring means in the processing tank of the processing machine main body, and a heating means for heating the inside of the processing tank. It is installed. An exhaust means for exhausting the air in the treatment tank and an air supply means for supplying air into the treatment tank are provided.

  Then, the control means performs the treatment by stirring the input garbage with the treatment material by the stirring means while maintaining the inside of the treatment tank within the predetermined temperature range by the heating means, and the moisture and odor after the treatment. Is removed by an exhaust fan while being removed by a catalyst heater.

  However, with this garbage processing machine, if the user does not throw in garbage due to long-term overnight stay, etc., not only wasteful power consumption will be performed by excessive stirring, heating and supply / exhaust, but also the processing material will deteriorate. There is a problem that the life span (usable period) is shortened and the microorganisms are killed in the worst case.

  The present invention has been made in order to solve the above-mentioned problems, and there is the following as prior art document information related to such a garbage disposal machine.

JP 7-171545 A JP 2002-126703 A JP 2004-209375 A

  In Patent Document 1, since it can be determined that the garbage is not thrown in if the lid of the slot is not opened and closed for three days, it is determined that the user is absent after that time has passed, and the heating means, the stirring means, etc. It is configured to execute the absence mode in which all are stopped.

  In Patent Literature 2, when the lid is not opened or closed for a predetermined period or more and the moisture content is equal to or lower than a predetermined value, the absence mode in which only the ventilation means is operated is executed. The absence mode is canceled by detecting the opening / closing of the lid.

  Further, in Patent Document 3, when the moisture content of the treatment material falls below a preset threshold value or falls below a preset number of times threshold value regardless of opening / closing of the lid, the absence of the weak operation of the exhaust means. It is configured to execute the mode.

  However, it is determined whether or not the absence mode of Patent Documents 1 and 2 is executed based on opening and closing of the lid. On the other hand, in recent years, there have been provided those in which the lid can be automatically opened by a human body sensor or the like. Therefore, in the case where such automatic opening is possible, there is an inconvenience that the absence mode is canceled when the lid is unintentionally opened by the user, such as when a small animal is detected while staying outside.

  In the absence mode of Patent Document 1, since all the treatment material adjusting means such as the heating means and the stirring means are stopped, when the absence mode execution time is long, oxygen is insufficient, and the treatment material has mold or the like. There is a problem that occurs. In the worst case, there is a problem that microorganisms (such as Bacillus) are killed.

  In the absence mode of Patent Documents 2 and 3, since the ventilation means is operated, problems such as mold can be suppressed, but supply or ventilation to the processing material located at the bottom of the processing tank cannot be expected. Therefore, there is still a problem that mold and the like are generated.

  The present invention has been made in view of conventional problems, and an object of the present invention is to provide a garbage processing machine that can reliably prevent deterioration of a processing material in accordance with a user's desire.

  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, an adjusting means for adjusting the activity of the processing material to a good state, and a control means for controlling the adjusting means. And a non-introduction period input unit for inputting a non-introduction period of raw garbage into the processing tank, and the control means receives the non-introduction period, An absence mode is provided in which the operation of the adjusting means is suppressed and controlled until a period elapses.

  According to this garbage disposal machine, when a non-injection period is input by an operation of the non-introduction period input unit, the absence mode is executed until the period elapses. Never happen. And in this absence mode, since the adjustment means is suppressed and controlled, it is possible to reliably suppress the deterioration of the treatment material. Moreover, the power consumption when not in use can be reduced by the suppression control.

  In this garbage processing machine, it is preferable that the non-introduced scheduled period is input as a number of days or a time, and in the absence mode, the control unit performs the suppression control so that the operation of the adjusting unit varies depending on the input period. In this way, it is possible to more reliably suppress deterioration of the treatment material.

  Further, the adjustment means includes a stirring means for stirring the garbage and the processing material in the processing tank, and the control means is configured to turn on the stirring means in a non-input state during the non-input period. In the absence mode, it is preferable to control so that the on-time ratio in one cycle is shorter than in the non-input state. In this way, the processing material can be stirred and air can be supplied without deteriorating the processing material due to excessive stirring in the absence mode.

  Further, the adjusting means includes a heating means for heating the processing material in the processing tank, and the control means controls the heating tank by on / off control in an uninput state during the non-input period. It is preferable to control the inside so as to be maintained at a predetermined temperature, and to control the operation of the heating means in the absence mode. If it does in this way, excessive drying of a processing material can be prevented in absence mode.

  Furthermore, the adjusting means includes exhaust means for exhausting the air in the processing tank, and the control means is configured to turn the exhaust means on and off times set in advance in the non-input state of the non-input period. It is preferable to perform control so as to repeat the cycle consisting of: and in the absence mode, control is performed such that the on-time ratio in one cycle is shorter than in the non-input state. In this way, outside air can be taken in after preventing excessive drying of the treatment material in the absence mode.

  Further, the adjusting means includes an air supply means for supplying air into the processing tank, and the control means is configured to turn the air supply means on and off in a preset on-time in the non-input state of the non-input period. It is preferable to perform control so as to repeat a period of time, and to control operation of the air supply means in the absence mode. In this way, it is possible to prevent the treatment material from being excessively dried in the absence mode and to prevent the treatment material having a tendency to dry out from being scattered.

  Furthermore, a means for detecting the state of the treatment material based on the water content or temperature of the treatment material in the treatment tank is provided, and the control means is based on the detection value of the detection means in the non-input state during the non-input period. It is preferable that correction control of the adjustment unit is performed and detection by the detection unit is stopped in the absence mode. In this way, useless power consumption can be reduced.

  In this case, it is preferable that the control unit executes the absence mode when the non-input period is input and the state of the treatment material based on the detection value of the detection unit is set in advance. In this way, since the absence mode in the overhumid state can be prevented, generation of mold and scattering of off-flavors can be prevented.

  In the garbage processing machine of the present invention, since the absence mode is executed until the non-input period elapses, the absence mode is not canceled without the user's intention. And in this absence mode, since the adjustment means is suppressed and controlled, it is possible to prevent molds and the like from being generated on the processing material, to suppress the deterioration of the processing material, and to save energy.

A case 37 is disposed for disposing the distance measuring sensor 36 at a predetermined height from the floor surface. The distance measuring sensor 36 includes a light emitting element and a light receiving element that receives reflected infrared light projected from the light emitting element.

  The lid body 38 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 39 which is an urging means. A pressing member 40 that protrudes downward in an arc shape is provided in the vicinity of the hinge connecting portion, and is configured so that the open and closed states of the lid 38 can be detected by turning on and off the switch 41 by the pressing member 40. is doing.

  Further, as a means for detecting the water content of the treatment material, a pair of electrodes 46 a and 46 b are disposed so as to be located inside the treatment tank 21. These electrodes 46a and 46b are arranged so as to be opposed to each other in plan view of the processing tank 21 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. Accordingly, the electrodes 46a and 46b 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 46a and 46b are incorporated as a single resistor, for example.

  Further, a display panel 47 that is a display means for displaying an operation state and a setting state of the garbage processing machine is disposed on the front upper portion of the exterior body 11. In addition, an operation panel 54 serving as an input means for changing (inputting) the operation state and setting state of the garbage processing machine is disposed below the display panel 47 or at a predetermined position.

  As shown in FIG. 4A, the display panel 47 includes an opening button 48 for operating a mechanical opening mechanism (not shown) for forcibly opening the lid 38 at the center thereof. In the upper part of the display panel 47, a period display unit 49 indicating the usage period of the processing material (bio-base material) is provided on the left side, and a processing material state display unit 50 indicating the state of the processing material is provided on the right side. Yes. Further, on the lower left side of the display panel, a filter cleaning display unit 51 indicating that it is time to clean the filter 31 is provided, and a deodorization display unit 52 indicating whether the deodorizing function is on or off is provided. Further, on the lower right side of the display panel 47, there is provided a non-insertion period display section 53 in a digital display format which means that the user is absent due to going out or the like.

  As shown in FIG. 4B, the operation panel 54 includes an ON / OFF switch 55 for operating or stopping the entire device, and a base material for resetting the use period by operating when the processing material is replaced. The reset switch 56, the filter reset switch 57 for resetting the period of use by operating when cleaning the filter 31, the deodorization switch 58 for selecting on / off of the deodorization function, and the non-introduced period due to overnight etc. An un-inserted switch 59 is provided for operation when it is understood in advance.

  As shown in FIG. 1, a drive motor 24, an electric heater 28, blower fans 30 and 32, a drive circuit for the catalyst heater 35, electrodes 46 a, A control board 60 on which a voltage application circuit to 46b and peripheral circuits such as temperature sensors 44 and 45 and a thermistor are mounted and connected is disposed. And the microcomputer 61 which is a control means mounted in this control board 60 is operate | moved according to the program set beforehand by connecting the power outlet which is not shown in figure to a commercial power source. In this embodiment, whether or not a non-input period is input by operating the non-input switch 59, control is executed in the standard mode if not input, and control is executed in the absence mode if input is performed. It is configured to do.

  Specifically, in the standard mode in which the unused period is not input, the microcomputer 61 first serves as a lid opening means, and approaches the range in which an object including a human body can be detected by the distance measuring sensor 36. If this is detected, the locking means 43 is operated to release the locking of the locking receiving portion 42, whereby the lid 38 is automatically opened by the biasing force of the hinge spring 39. At this time, when the stirring member 23 is operating (rotating), the lid 38 is opened after stopping the operation of the stirring member 23, and when the stirring member 23 is not operating, the opening process is performed as it is. Do.

  When the switch 41 detects that the lid 38 is closed, the built-in timer starts measuring time with the closed time as the starting point of control, and the stirring member 23, which is a processing material adjusting means, rotates. Then, on / off of the electric heater 28, on / off control (first adjustment process) of the blower fans 30, 32 and the catalyst heater 35 are started. Accordingly, the microorganisms supported on the treatment material are always brought into contact with fresh air in an appropriate temperature and humidity state to promote activation.

  Furthermore, the state of the processing function (moisture content) of the processing material is determined based on the detection values by the electrodes 46a and 46b every predetermined time (2 hours), and the control of each component is adjusted and displayed based on the determination result. The information is displayed on the processing material state display unit 50 of the panel 47. 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 44 and 45 and the detected humidity by the electrodes 46a and 46b 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. However, in this embodiment, the display part which shows a dry state is not provided.

  On the other hand, in the absence mode in which the non-input period is input, the heating function by the electric heater 28, the air supply function by the second blower fan 32, the deodorizing function by the catalyst heater 35, the temperature sensor 44, until the input period elapses. 45, the processing material state detection function by the electrodes 46a and 46b, the automatic opening function of the lid 38 by the distance measuring sensor 36 are stopped, the stirring function by the stirring member 23, and the air supply / exhaust function by the first blower fan 30 are standard. Compared with the mode, the on-time ratio in one cycle is shortened and the suppression control is performed. In addition, the control is configured to be different depending on the input period.

  Incidentally, the change of the non-insertion period display unit 53 by the operation of the non-insertion switch 59 can be changed in the period from 2 days to 99 days. Incidentally, in this kind of garbage processing, when new garbage is thrown in, it takes a period of about one day for the processing, so that “one day” cannot be input as a non-throwing period. In addition, the non-insertion period display unit 53 is changed by incrementing (increase) the non-insertion switch 59 every day for a short operation of less than 3 seconds, and every 5 days for a long operation lasting for more than 3 seconds. Increment display. Further, when the non-insertion switch 59 is operated in a state where the non-insertion period is “99”, the setting is changed to unset (turned off).

  When the non-introduction period is input, the absence mode is basically continued until the period elapses regardless of whether the lid 38 is opened or closed. Therefore, in the present embodiment, when the user returns home due to a schedule change, the absence mode is canceled by setting the non-input period to an unset state by operating the non-input switch 59. .

  Next, the garbage disposal control process by the microcomputer 61 will be specifically described.

  In this garbage disposal control process, as shown in FIG. 5, the microcomputer 61 first detects whether or not a non-input period is input in step S1. If it is not input, the process proceeds to step S2. If it is input, the process proceeds to step S13.

  In step S <b> 2, it is determined whether a request for opening the lid 38 is detected via the distance measuring sensor 36. If an opening request is detected, the process proceeds to step S3. If an opening request is not detected, the process proceeds to step S7. The opening by the opening button 48 is detected by the switch 41.

  In step S3, after stopping the adjusting means such as the stirring member 23, the electric heater 28, and the blower fans 30 and 32, the locking means 43 is operated in step S4 to open the lid 38. Next, in step S5, it waits until it is detected that the lid body 38 is closed via the switch 41. When the closure of the lid body 38 is detected, it means that the lid body 38 is just opened in step S6. After inputting 1 to the flag f to be performed, in step S7, the detection period timer (2 hours) for measuring the period for detecting the state of the processing function based on the moisture content of the processing material is reset and started, and then step S8 is started. Proceed to

  In step S8, it is detected whether or not the detection cycle timer timer has counted up. If the count is up, the process proceeds to step S9. If the count is not up, the process proceeds to step S12.

  In step S9, 0 is input to the flag f. In step S10, the detection cycle timer is reset and started in order to detect the state of the processing function of the processing material, and then the electrodes 46a and 46b are started in step S11. The processing material state detection process by is executed, and the process proceeds to step S12.

  In step S12, a stirring control process including the drive motor 24 and the stirring member 23, a heating control process using the electric heater 28, a display means changing process for the operation panel 54 that displays the state of the processing material, and a supply by the blower fans 30 and 32. A first adjustment process including an exhaust process and a deodorizing process by the catalyst heater 35 is executed, and the process returns to step S1. Note that each process in the first adjustment process is executed in parallel.

  Here, immediately after the user throws in the garbage, the process goes to step S12 through steps S1 to S8. 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 38, 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.

  On the other hand, if the uncharged period is input in step S1, whether or not the flag f is 1 in step S13, that is, whether or not immediately after the garbage is thrown by opening the lid 38 is determined. Detect whether or not. If f is 1 (immediately after the input), the process proceeds to step S8. If f is 0 (not immediately after the input), the process proceeds to step S14.

  In step S14, it is detected whether or not the state of the processing material based on the detection value detected in step S11 is “stickiness”. If it is in the “sticky” state, the process proceeds to step S8, and if it is not in the “sticky” state, the process proceeds to step S15.

  In step S15, a stirring control process including the drive motor 24 and the stirring member 23, a display means changing process for the operation panel 54 excluding the state of the processing material, and a second adjustment process including an exhaust process using only the first blower fan 30 are performed. Execute and proceed to step S16. Each process in the second adjustment process is executed in parallel as in the first adjustment process.

  In step S16, it is detected whether or not the non-input period has elapsed. Then, when the non-input period has elapsed, the process proceeds to step S8, and when the non-input period has not elapsed, the process returns to step S15.

  In the flowchart, the routine returning from step S1 to step S12 to step S1 is the standard mode, and the routine from step S1, step S13 to step S16 is the absence mode. Further, in the second adjustment process in the absence mode, the processing contents (the first absence mode and the second absence mode) differ depending on whether the setting of the unintroduced period is from 2 days to 7 days or more than 8 days.

  Specifically, in the first adjustment process in the standard mode, the agitation control process, the exhaust control process, and the air supply control process are performed in advance based on the moisture content of the processing material detected in step S11. It is controlled to repeat a cycle consisting of In addition, the heating control process, the deodorization control process, the detection process, the lid opening process, and the display process are controlled regardless of the water content of the processing material.

  In this embodiment, as shown in FIG. 6 (A), one cycle is 10 minutes. FIG. 6A shows a case where the water content is in a “sticky” state. The stirring control process has an on time of 2 minutes and the off time is 8 minutes, and the exhaust control process has an on time of 10 minutes and an off time. Is set to 0 minutes, and the on-time is set to 8 minutes and the off-time is set to 2 minutes so that the air supply control process is opposite to the stirring control process. Note that these ON times are shorter when the treatment material is in the “good” state, and are further shorter when the treatment material is in the “dry” state. The heating control process is always on / off controlled based on the detection values of the temperature sensors 44 and 45, and the deodorization control process is always on / off controlled based on the detection value of the thermistor 34. Further, the lid opening means and the display means are always operated in the same manner. However, the deodorization control process is not operated when the user cancels the execution by operating the switch on the operation panel 54.

  In the second adjustment process in the absence mode, the agitation control process and the exhaust control process are controlled to repeat a cycle including a preset on time and off time. In the display process, only the non-insertion period display unit 53 is decremented (decreased) based on the elapsed time, and the other display units 49 to 52 are turned off. Furthermore, other heating control processing, air supply processing, deodorization processing, detection processing, and lid opening processing are stopped.

  In the second adjustment process in the first absence mode in which the non-injection period is within one week, as shown in FIG. 6B, one cycle is set to 60 minutes. Among them, the stirring control process has an on time of 5 minutes and an off time of 55 minutes, and the exhaust control process similarly has an on time of 5 minutes and an off time of 55 minutes.

  Further, in the second adjustment process in the second absence mode in which the non-introduction period is longer than one week, one cycle is set to 120 minutes as shown in FIG. Among them, the stirring control process has an on time of 5 minutes and an off time of 115 minutes, and the exhaust control process similarly has an on time of 5 minutes and an off time of 115 minutes.

  Thus, the garbage processing machine of this embodiment is provided with the 1st absence mode and the 2nd absence mode, and the stirring member 23 which is a stirring means as an adjustment means so that an aerobic microorganism may not die, respectively. Only the 1st ventilation fan 30 which is an exhaust means is operated. Moreover, the operation time is configured such that the on-time ratio in one cycle is shortened. These absence modes are executed when the user inputs an unintroduced period by operating the unintroduced switch 59, which is an unintroduced period input unit, and are executed until the period elapses. Incidentally, in order to forcibly (intentionally) release the user, it is necessary to clear the non-input period by operating the non-input switch 59.

  That is, the absence mode is not canceled without the intention of the user, and in this absence mode, the control of all the adjusting means is changed. The suppression control in the absence mode is the minimum necessary operation that can be maintained to the extent that the microorganisms of the treatment material are not killed, and is made different depending on the period input by the user. It is possible to reliably suppress the power consumption when not in use.

  Specifically, as suppression control of the adjusting means, in the absence mode, the ON time ratio of the stirring member 23 in one cycle is shortened, so that the processing material is not deteriorated by excessive stirring. Agitation and air supply can be performed. Similarly, in the absence mode, the first blower fan 30 serving as the exhaust means reduces the on-time ratio in one cycle. Thus, outside air can be taken in from the air supply port 17.

  On the other hand, the operation of the electric heater 28 serving as a heating unit is stopped in the absence mode, so that excessive drying of the treatment material can be prevented. Similarly, since the second blower fan 32 serving as the air supply means stops operating in the absence mode, it is possible to prevent the treatment material from being excessively dried and to prevent the treatment material that tends to dry out from being scattered.

  Moreover, in the absence mode, the operation of the electrodes 46a and 46b and the temperature sensors 44 and 45, which are detection means for detecting the state of the processing material, is stopped, so that useless power consumption can be reduced. On the other hand, the absence mode is executed when the state of the treatment material based on the detection values of the electrodes 46a and 46b, which are detection means, is set in advance after the non-input period is input. In other words, since it is configured not to be executed in a “sticky” state where there is excessive moisture, generation of mold and scattering of off-flavors can be prevented.

  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 embodiment, the configuration is such that the period when the garbage is not thrown in is input in days, but the configuration may be such that the time is input. Further, the non-insertion period display unit 53 is configured as a digital input method and is configured to be incremented by operation of the non-insertion switch 59. However, a plurality of preset periods and LED display units are provided and changed every time the switch is operated. It is good. In other words, the input method including the reset method for the non-input scheduled period can be changed as desired.

  Moreover, in the said embodiment, although two types of absence modes which perform different control based on the inputted non-input period are used, you may make it 3 or more types.
