Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage processing apparatus for performing garbage drying or decomposition treatment by a fermentation method, and a garbage processing method in the apparatus.

[0002]

2. Description of the Related Art Hitherto, for example, a structure as disclosed in Japanese Patent Application Laid-Open No. 10-99841 has been known as a decomposition treatment apparatus using a fermentation method. A rotary shaft having a plurality of stirring blades is rotatably provided in a processing tank of the garbage processing apparatus. In the processing tank, a processing medium such as wood chips such as sawdust and a microorganism culturing substrate is stored in advance, and garbage introduced into the processing tank from an input port is rotated by the rotation shaft. Accordingly, the mixture is stirred and mixed with the processing medium while being heated by the stirring blade. Then, the garbage is dried and decomposed by the decomposition action of the processing medium in the processing tank, and then pushed out from the garbage discharge port formed in the side wall of the processing tank by a stirring blade to the outside, and the garbage is discharged. It is designed to fall and be stored in another container set below the outside of the outlet.

[0003]

However, the conventional garbage processing apparatus has the following problems. That is,
It takes a relatively long time to stir and mix the garbage with the processing medium while drying and decomposing the garbage in the processing tank. Therefore, when new garbage is introduced from the inlet after a certain period of time from the start of the agitation and decomposition processing of garbage in the processing tank, the processed garbage that has been subjected to the dry decomposition processing is introduced into the processing tank. Immediately after being processed, unprocessed garbage that has not been dried and decomposed is mixed. In general, a rotating shaft provided with stirring blades in a processing tank is controlled so that its rotating direction is alternately switched at predetermined time intervals and rotates forward and backward. Therefore, as described above, when the rotation direction of the rotating shaft is switched and controlled in a state where the processed garbage and the unprocessed garbage are mixed, not only the processed garbage but also the unprocessed garbage can be discharged from the garbage discharge port. There is a problem of being discharged.

On the other hand, in order to prevent such a problem, in the above-mentioned conventional garbage disposal apparatus, a cap is detachably provided at the garbage discharge port, and when the processed garbage is discharged (taken out). Discloses that a user removes the cap, and then sets another container below the outside of the outlet. However, if the user performs the cap attaching / detaching operation one by one as described above, the attaching / detaching operation becomes troublesome. In addition, along with the cap removal operation, the user must perform a control operation so that the rotation direction of the rotating shaft is switched to a direction in which the agitating blade pushes up the garbage toward the discharge port. Increase. This problem also occurs as a problem such as discharge of undried matter in a processing apparatus that performs only the drying process without the above-described fermentation method.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a garbage disposal system capable of efficiently collecting only processed garbage that has been subjected to a treatment such as drying or decomposition. An object of the present invention is to provide an apparatus and a method for treating garbage in the apparatus.

[0031]

[Table 1] (Control device) As shown in FIG.
Inside, a control device 71 composed of a CPU and the like is disposed above the collection container 44 via a partition wall S. This partition wall S blocks heat from the heated oxidative deodorizing catalyst. The control device 71 controls the operation of various internal devices such as the heater 33, the stirring motor 38, and the exhaust fan 53 in the garbage disposal device 21.

1. The melody speaker 77 for generating a melody, the heater 33 and the stirring motor 38 are connected.

(Rotation Sensor) The rotation sensor 72 detects the number of rotations of the stirring motor 36 and outputs a rotation signal to the control device 71. The control device 71 controls the rotation and stop of the stirring motor 38 based on the rotation signal. That is, the control device 71 counts a signal input from the rotation sensor 72, and when this signal input is too early or too late for some reason, it is determined that the stirring is abnormal and the stirring motor 36 is stopped, and the error is detected. The lamp 62a blinks. As a cause of this, it is conceivable that the garbage in the processing tank 31 is locked by the stir bar 39 being stuck.

(Temperature Sensor) The temperature sensor 73 detects the temperature in the processing tank 31 and outputs a temperature detection signal to the control device 71. The control device 71 controls ON / OFF of the heater 33 based on the temperature detection signal. That is, when the internal temperature of the processing tank 31 detected by the temperature sensor 73 exceeds a predetermined temperature range, the controller 71
Stops power supply to the heater 33 and lowers the temperature in the processing bath 31.

When the internal temperature of the processing tank 31 falls below a predetermined temperature range, the controller 71
3 and the temperature in the processing tank 31 is increased. By repeatedly turning on and off the heater 33, the internal temperature of the processing bath 31 is maintained within a predetermined temperature range. Normally, the internal temperature of the processing tank 31 is set to an activation temperature at which garbage is easily fermented, and is set to about 70 ° C. in the present embodiment.

The control device 71 is adapted to operate in a case where the temperature in the processing tank 31 is lower than a predetermined temperature range even after a predetermined time has passed since the start of energization of the heater 33. Then, it is determined that the heat retention is abnormal, the heater 33 is turned off, and the error lamp 62a is turned on and off.

(Open detection sensor) Open detection sensor 7
4 includes a permanent magnet M provided on the closing lid 14 side and a reed switch Rs provided on the waste duct 12. The opening detection sensor 74 detects the attachment / detachment of the closing lid 14 when the magnet M approaches or separates from the reed switch Rs with the attachment / detachment of the closing lid 14, and outputs an opening / closing signal to the control device 71. Based on this opening / closing signal, the control device 71 causes the error lamp 62a to blink.

(Attachment / Removal Detection Sensor)
Reference numeral 5 includes a magnet (not shown) provided on the collection container 44 side and a reed switch (not shown) provided on the main body case 21a side. The attachment / detachment detection sensor 75 detects attachment / detachment of the collection container 44 when the magnet approaches and separates from the reed switch with attachment / detachment of the collection container 44, and outputs an attachment / detachment signal to the control device 71. On the basis of the attachment / detachment signal, the control device 71 blinks the error lamp 62a.

(Others) The rotation sensor 72 and the temperature sensor 73 constitute abnormality detecting means for detecting at least one or more abnormal states assumed in advance as abnormal states regarding the garbage disposal apparatus 21. The opening detection sensor 74 and the attachment / detachment detection sensor 75
And an interference detecting means for detecting a predetermined interference operation assumed in advance as a user's interference operation with respect to.

Further, the buzzer speaker 76 and the display panel 61 constitute an abnormality notifying means for notifying the abnormal state detected by the abnormality detecting means by hearing and vision. The melody speaker 77, based on the detection result of the interference operation by the interference detection means,
When the abnormality notification unit does not perform the abnormality notification, an interference notification unit configured to perform the interference notification in a voice mode different from that of the abnormality notification unit is configured. (Operation of Embodiment) Next, the operation of the garbage disposal apparatus 21 configured as described above will be described.

(Non-garbage disposal) During normal use of the sink 11 which does not perform garbage disposal, the closing lid 14 is in a mounted state, and the space between the waste duct 12 and the inlet 22 is shut off in a watertight manner. I have. The kitchen wastewater and the garbage thrown into the waste duct 12 are separated by the garbage basket 13, and the kitchen wastewater is drained to the outside via a drain pipe 15 connected to a lower part of the outer periphery of the waste duct 12.

(During garbage disposal) On the other hand, when performing garbage disposal, the garbage basket 13 in which garbage is accumulated is removed, the closing lid 14 is removed, and communication between the waste duct 12 and the inlet 22 is performed. Let it. When the garbage in the garbage basket 13 is dropped into the waste duct 12 in this state, the garbage falls into the treatment tank 31 via the waste duct 12, the connecting member 23 and the input port 22. In addition, when the raw garbage is to be charged for the first time, a substrate to be stirred together with the raw garbage is charged into the processing tank 31. In this embodiment, charcoal (not shown) having a large deodorizing effect is used as the base material. The odor generated from the garbage in the treatment tank 31 is reduced by the deodorizing action of the charcoal.

(Garbage Disposal Method) (Input) After the detection of the input of the garbage, that is, after the closing lid 14 is attached and the closing signal is output from the opening detecting sensor 74, the control device 71 drives and controls the stirring motor 38. Then, the stirring bar 39 is moved in a direction in which no overflow occurs, that is, in FIG.
Is rotated in the direction of arrow A for a predetermined time (1 to 8 hours) and at fixed time intervals. The garbage in the treatment tank 31 is stirred with the base material while being kept at a predetermined activation temperature by the rotation of the stirring rod 39, thereby promoting fermentation decomposition.

At this time, the garbage in the processing tank 31 moves in the directions of arrows C1 and C2 in FIG. The reason why the garbage moves in the direction of arrow C1 is that a propulsive force acts on the garbage in the direction in which the right-handed screw advances by the rotational force of the stirring rod 39.

The garbage moves in the direction of arrow C2 because the garbage is scraped up along the inner wall of the processing tank 31 when the stirring rod 39 rotates upward. When the forces in the directions of arrows C1 and C2 simultaneously act on the garbage, the upper surface of the garbage is inclined so as not to reach the discharge port 41. Therefore, untreated garbage that has not been sufficiently fermented and decomposed is not discharged from the outlet 41.

(Discharge) When the garbage is sufficiently fermented and decomposed after a predetermined time has elapsed from the start of stirring, the control device 7
Numeral 1 controls the driving of the stirring motor 38 in the direction opposite to that described above, and rotates the stirring rod 39 in the direction in which overflow occurs, that is, in the direction of arrow B in FIG. Let it. The processed garbage in the processing tank 31 is indicated by an arrow D in FIG. 9 for the same reason as described above.
1, and moves in the direction of D2, that is, the direction in which the discharge port 41 approaches and concentrates. Then, the upper surface of the processed garbage is inclined so as to reach the outlet 41, and the processed garbage is gradually discharged from the outlet 41. The discharged processed garbage passes through the inside of the passage member 42 and is dropped and stored in the collection container 44.

The timing of starting the overflow operation of the garbage disposal apparatus 21 is determined by detecting the moisture content of the garbage in the processing tank 31 by a discharge timing detection sensor (not shown). That is, the garbage in the processing tank 31 is
Since it is heated by 3, the moisture content of the treated garbage is significantly smaller than the moisture content of the untreated garbage. Utilizing this, when the moisture content of the garbage in the processing tank 31 is less than a predetermined value range, the discharge timing detection sensor outputs a garbage processed signal to the control device 71. If the value exceeds a predetermined value range, the discharge timing detection sensor outputs a raw garbage unprocessed signal to the control device 71.

As described above, the unprocessed garbage is not discharged because the garbage is fermented and decomposed and discharged properly in accordance with the garbage processing state in the processing tank 31. In addition, the control device 71 stops the stirring rod 39 closest to the discharge port 41 so that the garbage scraped up by the stirring rod 39 stops rotating at a position where the discharge port 41 is not blocked. The drive of the motor 38 is controlled. In the present embodiment, the rotation of the stirring rod 39 closest to the discharge port 41 is stopped at a position directly above. Therefore, the stirring rod 3
Even when the rotation of the stirrer 9 is stopped, the discharge port 41 is not blocked by the stirring bar 39 or the garbage scraped up by the stirring bar 39.

(Exhaust) During the operation of the garbage disposal device 21, the control device 71 operates the deodorizing heater 56 based on the setting of the deodorizing mode by the deodorizing mode selection switch 63. When the deodorizing mode is set to "automatic", the deodorizing heater 56 is operated for a predetermined time (6 hours is set in the present embodiment) after the "close" of the closing lid 14 is detected. If “continuous” is set, the deodorizing heater 56
Is always activated. Note that the exhaust fan 53 is constantly operated.

The odor generated from the garbage in the processing tank 31 is sucked by the operation of the exhaust fan 53 and
1, exhaust filter 52, exhaust fan 53, exhaust pipe 54,
The air is forcibly exhausted outside through the deodorizing device 55 and the exhaust hose. Therefore, leakage of the odor of the garbage into the room is prevented as much as possible. Fine particles such as charcoal fine powder used as a base material are filtered by an exhaust filter 52, and only a pure gas is exhausted outdoors. Further, the odor is supplied to a deodorizing device 5.
The exhaust gas is made almost odorless by the deodorizing action of the oxidizing and deodorizing catalyst incorporated in 5, and is exhausted outdoors.

(Intake) On the other hand, by the operation of the exhaust fan 53, the odor in the processing tank 31 is exhausted, and fresh air flows into the processing tank 31 through the intake passage. That is, fresh air outside the device 21 is supplied to a gap formed between the outer surface of the processing tank 31 and the inner surface of the main body case 21a → a void 47 → a collection container 44 → a passage member 42 → a discharge port 41.
→ It flows into processing tank 31 in order. The fresh air introduced into the treatment tank 31 further activates the aerobic decomposing bacteria of the garbage itself, and as a result, the fermentation and decomposition of the garbage is promoted. The air flowing into the processing tank 31 from the outlet 41 is
The odor staying in the processing tank 31 is pushed out from the exhaust port 51, and is exhausted to the outside through the exhaust passage together with the odor.

As described above, since the collection container 44 is disposed in the middle of the intake passage and the receiving port 44a faces the intake passage, when the intake fan is started by the operation of the exhaust fan 53, the collection container 44 is started. The inside is in a negative pressure state. As a result, the odor of the processed garbage in the collection container 44 flows into the processing tank 31 via the passage member 42 and the discharge port 41. Further, since air flows into the processing tank 31 from the discharge port 41, in a state where the collection container 44 is removed,
The odor staying in the treatment tank 31 does not leak indoors through the outlet 41 and the passage member 42. That is, the discharge port 41 has an original function of discharging the processed garbage in the processing tank 31 to the outside, and a function as an intake port for taking in fresh air into the processing tank 31 from outside the apparatus 21. It has.

(Utilization of Exhausted Heat) At the time of exhaust gas deodorization, the oxidizing and deodorizing catalyst incorporated in the deodorizing device 55 is heated to a high temperature of 250 to 400 ° C. by the incorporated deodorizing heater 56, and the outer wall of the deodorizing device 55 is also heated to 50 ° C. A relatively high temperature of ~ 80 ° C. Further, as shown in FIGS. 1 and 2, the deodorizing device 55 is located in the middle of the aforementioned intake passage, that is, in a gap formed between the outer surface of the processing tank 31 and the inner surface of the main body case 21a. Therefore, the device 21 is operated in accordance with the operation of the exhaust fan 53.
The exhaust heat from the outer wall of the deodorizing device 55 is transmitted to the air flowing in from the outside, and the heated air flows into the processing tank 31. That is, the garbage in the processing tank 31 is
Is heated by the exhaust heat of the deodorizing device 55 in addition to the Joule heat. For this reason, the inside of the processing tank 31 is efficiently heated and kept warm. The stirring motor 38 and the exhaust fan 53 are also arranged in the exhaust passage, and these also generate exhaust heat in the operating state. Therefore, the waste heat is also taken into the processing tank 31.

(Information Display) (Normal) When the garbage is put in, when the garbage disposal device 21 is normal and the closing lid 14 is removed by the kitchen user, the control device 71 issues an opening signal from the opening detecting sensor 74. Blinks the error lamp 62a based on the
The melody is played from the melody speaker 77. By this melody notification, the user is alerted that the closing lid 14 is in an open state, and water is prevented from entering the processing tank 31 when the closing lid 14 is opened. When the closing lid 14 is attached after the garbage is put in, the control device 71 turns off the error lamp 62 a based on the closing signal from the opening detection sensor 74 and stops the melody flowing from the melody speaker 77. For this reason, it is possible to prevent forgetting to attach the closing lid 14 after the input of the garbage.

(Error) On the other hand, when the garbage is thrown, the closing lid 14 is placed in a state where some error has occurred, such as the collection container 44 not being installed in the garbage disposal device 21, stirring abnormality, and heat retention abnormality.
Is removed, the control device 71 sets the sensors 72 to 72
The error lamp 62a blinks on the basis of the signal input from the speaker 75, and an intermittent warning sound (for example, "beep, beep, beep") indicating an abnormality is generated from the buzzer speaker 76. That is, in the normal state, the closing lid 1
By making the voice mode different from that when 4 was removed,
The user can determine that an error has occurred in the device 21.

(Determination of Error Type) The error lamp 6
When the kitchen user presses the error switch 62 when 2a blinks, the type of the above-mentioned error is identified and displayed on the display panel 61. That is, as shown in Table 1, when the closing lid 14 is removed, the LED corresponding to “OFF” of each deodorizing mode lamp 63a is turned on. When the collection container 44 is not installed, an LED corresponding to “automatic” among the respective deodorization mode lamps 63a is turned on. When the stirring is abnormal, the LED corresponding to “continuous” in the deodorizing mode lamp 63a is turned on. In the case of abnormal heat retention, the LED corresponding to “OFF” of each maintenance time display lamp 64a is turned on.

As described above, when removing the closing lid 14,
That is, if any error occurs in the device 21 when the user is near the garbage disposal device 21, a warning sound is generated. Nevertheless, the warning sound does not continue to be generated. Further, by notifying the error of the device 21 by voice, the occurrence of the error is notified to the user without the user checking the display panel 61 visually. In addition, the user can naturally recognize the occurrence of an error in the device 21 by visually checking the display panel 61, and can confirm the type of the error by pressing the error switch 62.

Therefore, according to the present embodiment, the following effects can be obtained. (1) When the garbage in the processing tank 31 is untreated garbage,
The stirring bar 39 rotates in a direction in which the garbage pushed up by the stirring bar 39 does not reach the outlet 41. In addition, processing tank 3
In the case where the garbage in 1 is treated garbage, the garbage pushed up by the stirring bar 39 is rotated in a direction to reach the discharge port 41. Therefore, the processing tank 31
If the garbage inside is untreated garbage, the garbage is
In the case of processed garbage, the garbage is discharged from the discharge port 41. Therefore, it is possible to easily prevent the untreated garbage from being discharged from the discharge port 41. In addition, since the untreated garbage is not discharged from the outlet 41, only the processed garbage that has been subjected to the dry decomposition treatment can be efficiently collected.

(2) The stirring rod 39 rotates in a direction in which the garbage does not reach the discharge port 41 until a certain time has elapsed after the garbage is put into the processing tank 31, and after the lapse of the certain time, the garbage is removed. The stirring rod 39 was rotated in a direction reaching the discharge port 41. The garbage is decomposed after a certain period of time from being put into the processing tank 31, so that the processing tank 31
The rotation direction of the stirring rod 39 can be accurately switched in accordance with the state of processing the garbage inside. In addition, the decomposition and discharge of the garbage can be performed accurately.

(3) The timing of starting the overflow operation of the garbage disposal apparatus 21 is determined by detecting the water content of the garbage in the processing tank 31. That is, the overflow operation is started when the water content of the garbage in the processing tank 31 falls below a predetermined value range, that is, when the garbage decomposition process is completed. When the water content of the garbage in the processing tank 31 exceeds a predetermined value range, the decomposition process is continued. Therefore, for example, when new garbage is additionally introduced into the processing tank 31, the overflow operation is not started by detecting the moisture of the new garbage. Therefore, it is possible to avoid a possibility that untreated garbage is erroneously discharged.

(4) The discharge port 41 is formed at a position not including the central axis on one side wall of the processing tank 31. For this reason, by switching and controlling the rotation direction of the stirring rod 39, the decomposition processing of the garbage in the processing tank 31 and the discharge of the processed garbage can be accurately performed.

The above embodiment may be modified as follows. In this embodiment, the fermentation type processing apparatus is described in detail. However, the same overflow operation as described above can be obtained as a processing apparatus using only a drying process as a processing method.

In the present embodiment, it is determined whether the garbage has been processed or not, based on the water content of the garbage in the processing tank 31. Alternatively, the determination may be made by counting the elapsed time from the start. At this time, the count value of the elapsed time is cleared when the open state of the closing lid 14 is detected. By doing so, the closing lid 1
When the open state of No. 4 is detected, that is, every time new garbage is loaded into the processing tank 31, the count of the elapsed time since the last garbage was loaded is cleared. Then, the elapsed time since the new garbage is input is counted. Therefore, it is possible to prevent the untreated garbage additionally charged from being erroneously discharged.

In the present embodiment, the discharge port 41 is formed closer to the upper right side on one side wall of the processing tank 31, but may be formed closer to the upper left side. However, the rotation direction of the stirring bar 39 when the overflow operation is performed and when the overflow operation is not performed is opposite to that in the present embodiment. Also in this case, the decomposition and discharge of the garbage in the processing tank 31 can be accurately performed.

In the present embodiment, the garbage input port 22 is closed by the closing lid 14, but the following may be adopted. That is, the closing lid 14 is provided rotatably with respect to the insertion port 22, and the closing lid 14 is operatively connected to external operation means such as a foot pedal outside the device 21. And
By operating the external operation means, the closing lid 14 is configured to open and close. By doing so, the closing lid 1
4 can be easily opened and closed.

In the present embodiment, the processing tank 31 is a single tank, but a plurality of tanks may be formed by, for example, partitioning the inside of the processing tank 31 with a partition plate (not shown). Even in this case, it is possible to prevent the overflow from being started in accordance with the processing state of the garbage and discharging the untreated garbage.

Next, technical ideas other than the claimed invention which can be grasped from the embodiment will be described below together with their effects. The garbage disposal apparatus according to any one of claims 1 to 3, wherein the discharge port is formed at a position not including a central axis on one side wall of the processing tank.
