46 and the third receiving blade 47 are disposed near the left and right sides of the tip rotation trajectory of the tip blade 43a of the third stirring claw 43.
The stirring claw 42 is disposed near the right side of the tip rotation locus of the one-side tip blade 42a.

In this manner, the tip blades 41a, 41b, 42a, 42b, 43a of the stirring claws 41, 42, 43 and the receiving blades close to them.
The garbage can be crushed between 45,46,47,48.

As shown in FIGS. 3 and 5, the fourth stirring claw 44 is configured such that the one-side tip blade 44a and the other-side tip blade 44b are offset by a predetermined width in the left-right width direction in a front view. The one-sided tip blade 44a is arranged as shown in FIG.
The second stirring claw 42 is arranged so as to advance in a forward rotation direction, which is a clockwise clockwise direction, by a certain phase angle θ from the one end blade 41 a of the second stirring claw 42. When the fermented product scooped by the above overflows into the aging treatment tank 33 through the first overflow window 34, the fourth stirring claw
The timing is set so that one of the tip blades 44 is positioned to close most of the first overflow window 34.

Here, the phase angle θ is, for example, approximately 30 degrees to
It can be set in a range of approximately 45 degrees, and in this embodiment,
Approximately 30 degrees is adopted.

In the above-mentioned stirring means 31, each stirring claw is provided.
41, 42, 43, and 44 are driven forward and reverse by a stirring claw driving motor 50 as a driving unit.
As shown in FIGS. 3 and 4, the output shaft 50a is disposed on the left side and the lower rear position in the casing main body 10 so that the output shaft 50a is protruded leftward from the motor 50, and is stirred with the output shaft 50a.

Reference numerals 54 and 55 denote chain tension bodies for applying tension to the transmission chain 51, respectively. Numeral 75 is a motor rotation sensor.
The number of rotations of the stirring claw driving motor 50 is detected by 75.

In this way, in the garbage disposal section 2, as shown in FIG. 6, after the garbage is put into the fermentation treatment tank 32, the garbage is attached to the agitating claw support shaft 40 by the agitating claw driving motor 50. By reversely rotating the stirring claws 41, 42, 43, and 44 in a counterclockwise direction in a side view, the garbage can be fermented while stirring.

At this time, when the raw garbage is to be introduced for the first time, an auxiliary material (for example,
Sawdust, zeolite, and perlite) are added together with garbage to promote fermentation of garbage, and to prevent crushed and stirred garbage from being ground and liquefied, and to be as porous as possible. I do. And
Thereafter, the fermented product partially retained in the fermentation treatment tank 32 serves as a fermentation promoting function in place of the auxiliary material, and the garbage is kept for a certain period of time, for example, for one month.
It is kept in the chamber 32, and is fermented and further aged to be recovered as a final residue.

As shown in FIG. 7, the fermentation product subjected to the fermentation process is rotated clockwise in a side view by the respective stirring claws 41, 42, 43, 44 by a stirring driving motor 50. Thus, the fermentation product B scraped up by the second stirring claw 42 can overflow into the aging treatment tank 33 through the first overflow window 34.

At this time, each tip blade 44a, 44b of the fourth stirring claw 44 arranged in the aging treatment tank 33 is connected to each tip blade of the second stirring claw 42.
The fermentation product B scraped up by the second stirring claw 42 overflows into the aging treatment tank 33 from the first overflow window 34 because the fermentation treatment product B is arranged so as to be advanced by the phase angle θ in the forward rotation direction with respect to 42a and 42b. At this time, one end claw of the fourth stirring claw 44 closes most of the first overflow window 34 in a side view, and furthermore, the first overflow window 34 and the second overflow claw 44 are closed.
By providing a height difference of a fixed height H between the overflow window 35 and the overflow fermentation product B, a short path that is directly collected by the collection unit 3 through the second overflow window 35 can be prevented. I have to.

The fermented product transferred into the aging treatment tank 33 can be further fermented and aged while being stirred by the fourth stirring claws 44. Therefore, even fibrous plants that are not easily fermented in the aging tank 33 can be fermented and matured without fail.

At this time, in the aging treatment tank 33, the ripened product is transferred to the second overflow window by the fourth stirring claw 44 rotating forward.
Through 35, it is possible to overflow into the collecting section 3.

Here, when the fermentation treatment and the ripening treatment as described above are performed, the raw garbage processing tank 30 is heated by a planar heater 37 stretched on the arc-shaped bottom 30e of the garbage processing tank 30. A temperature sensor 76 and a humidity sensor 77 are provided below the left side wall 30a of the living garbage disposal tank 30.
The two sensors 76 and 77 are connected to a control unit 80 to be described later, and the temperature of the heater 37 is controlled by the control unit 80 so that the fermentation / ripening process can be performed at a desired temperature. I have to.

As shown in FIGS. 3 to 5, the collecting gutter 60 is attached by connecting the upper end portion 60a to a second overflow window 35 formed in the right side wall 30b of the garbage disposal tank 30. The lower end portion 60b extends downward from the position of the arc-shaped bottom portion 30e of the garbage disposal tank 30 by extending downward along the wall 30b. Reference numeral 78 denotes a discharge sensor, which detects a discharge time at which the final residue contained in the collection tray 61 is full.

As shown in FIGS. 3 to 5, the collecting tray 61 is formed in a horizontally-long rectangular box shape extending in the front-rear direction, and the casing main body located immediately below the lower end portion 60b of the collecting gutter 60.
It is placed on 10 floors 10d.

In this manner, the aged product aged in the aging treatment tank 33 of the garbage disposal tank 30 overflows into the collection gutter 60 through the second overflow window 35, and is collected through the collection gutter 60. It is to be collected within 61.

At the upper part, a horizontally long suction window 71 is formed in the left-right width direction, and a net 72 is stretched over the suction window 71.

Here, the deodorizer 65 contains rock wool obtained by baking rock and processing it into a flocculent shape. The rock wool propagates aerobic microorganisms that decompose malodorous components into the rock wool. The odor components in the exhaust gas are adsorbed on the exhaust gas, and the odor components are decomposed by aerobic microorganisms to release the deodorized exhaust gas.

An exhaust hole (not shown) is formed in the lower part of the deodorizer 65, and an exhaust hole 10e is formed in the floor 10d of the casing body 10 so as to be vertically aligned with the exhaust hole 10e.
An exhaust guide body 73 for guiding the exhaust air rearward along the lower surface of the floor 10d is attached to the vehicle.

As described above, in the deodorizing section 4, by operating the exhaust fan, the exhaust in the garbage processing tank 30 is exhausted by the exhaust passage 36 in the tank → the exhaust window 69 → the exhaust case 68 → the exhaust duct 67 → After being sucked into the exhaust fan case 66 and pumped into the deodorizer 65, deodorized in the deodorizer 65,
65 exhaust holes 10e → Exhaust holes in floor 10d of casing body 10

At this time, when the power supply current is 60 Hz, the rotation speed of the stirring claw driving motor 50 can be set to, for example, 4.0 rpm. When the current is 50 Hz, the rotation speed of the motor 50 can be set. Can be set to, for example, 3.5 rpm.

[Agitating Operation Control] In the agitating operation, as shown in FIG. 9, after the crushing operation is completed, the agitating claws 41, 42, 43, and 44 are reversely rotated for six minutes before one hour has elapsed. The operation is repeated five times in succession, and thereafter, the operation in which the stirring claws 41, 42, 43, and 44 are rotated forward only for six minutes before one hour elapses continuously until the charging lid 12 is opened. It is.

When the charging lid 12 is opened during the stirring operation, the timer is reset as shown in FIG. 10, and the crushing operation is executed from the beginning.

Therefore, seven hours after the closing of the charging lid 12, the stirring claws 41, 42, 43, and 44 rotate forward again.

In this way, the setting is made such that the stirring claws 41, 42, 43, 44 are always rotated forward during one cycle, with 24 hours as one cycle, and the fermentation treatment tank 32 → ripening treatment tank 33
The fermentation treatment product overflows through the first overflow window 34, and the agitation treatment tank 33 → the collection gutter 60 overflows the aging treatment product through the second overflow window 35 to perform the agitation and overflow operation. By preventing the amount of the processed material in the processing tanks 32 and 33 from increasing beyond a predetermined amount, the fermentation and aging treatment can be appropriately performed in each of the processing tanks 32 and 33.

[Temperature Control] In the temperature control, the temperature in the garbage disposal tank 30 heated by the heater 37 is controlled based on the detection result of the temperature sensor 76.
The temperature control in the (crushing process), the (fermentation process), and the (aging process) will be described.

(Crushing Step) In the crushing step, during the initial crushing operation for 2 hours in one cycle, a germicidal treatment temperature of 50 ° C. to 80 ° C. for sterilizing anaerobic bacteria adhering to garbage. C., preferably 65 ° C., and the garbage is crushed under the sterilization temperature conditions.

In this way, the anaerobic bacteria adhering to the garbage are heat-sterilized while the garbage is crushed to eliminate the odor generated by the anaerobic bacteria.

(Fermentation Treatment Step) In the fermentation treatment step, for 12 hours during the stirring operation started after the end of the crushing operation, a fermentation treatment temperature lower than the sterilization treatment temperature is 40 ° C. to 60 ° C., preferably, The temperature is set at 50 ° C., and the garbage crushed is fermented under the fermentation temperature conditions.

The motor 50 and the exhaust fan drive motor 81 are immediately stopped, and when the closing lid open / close detection switch 15 or the discharging lid open / close detection switch 16 detects that the closing lid 12 or the discharging lid 14 has been changed from the open state to the closed state. ,
In this operation, the motors 50 and 81 are continuously driven immediately.

[Motor Overload Control] In the motor overload control, as shown in FIG. 13, one second after the start of the driving of the stirring claw driving motor 50, the motor rotation sensor 75 outputs a pulse every 500 ms. Counting, when the rotation speed of the motor 50 becomes 800 rpm or less, it is determined that an overload has acted on the motor 50, the motor 50 is stopped for 5 seconds, and then the motor 50 is rotated with the rotation before the stop. This is a control in which the motor is rotated in the reverse direction for 20 seconds, then stopped for 5 seconds, and then the operation before the overload is applied is continued.

This operation is repeated up to three times, and if an overload is still acting, the motor 50 for driving the agitating claw is stopped and the motor overload indicator lamp 83 is flickered. However, the heater 37 maintains the state before the motor overload control.

This maintenance state is continued until the power supply is turned off, and when the power supply is turned on next time, the maintenance state is resumed from the state before the motor overload control. I have.

[Answering operation control] The answering machine operation is shown in FIG.
As shown in, the closing lid opening and closing detection switch 15 does not detect the opening and closing of the closing lid 12 within 48 hours which is a short answering machine set time, and stops the stirring claw driving motor 50,
The temperature is controlled by the heater 37, the temperature is set to 40 ° C., which is the aging temperature, and the same state is maintained.

After that, if the opening / closing opening / closing detection switch 15 does not detect the opening / closing of the closing lid 12 within 120 hours which is the long-term answering machine set time, the heater 37 is stopped, and the exhaust fan driving motor is stopped. I try to stop 81.

In the answering machine operation, the crushing operation is started immediately when the opening / closing detection switch 15 detects the opening / closing of the charging lid 12, and the drying switch 79 is continuously turned on for 5 seconds.
When N is performed, the drying operation is started immediately.

Thus, when the user goes out and returns home within the long absence time, the garbage disposal is continued at the aging temperature, and the user returns home outside the long absence time. In such a case, the garbage disposal operation is stopped after the garbage disposal is completed, so that the garbage disposal can be performed even when the user is away and the running cost can be prevented from being wasted. ing.

In the above description of the control, specific numerical values for time, temperature, number of times, etc. are described.
These are only specific examples of preferable numerical values, and the present invention is not limited to these numerical values.

[0089]

According to the present invention, the following effects can be obtained.

That is, in the present invention, if the detection of the opening / closing operation of the loading lid by the loading lid open / close detection sensor is not made within the set time, the control of the drive unit and heater of the stirring claw is changed.

In this manner, for example, when the user goes out and returns home within the long-term answering machine set time, the drive unit of the stirring claw and the heater are controlled so that the garbage disposal is continued at the aging temperature. Change the control, and change the control of the drive unit and heater of the stirring claw so that the garbage disposal operation is stopped when the garbage disposal is completed when returning home outside the long-term answering machine set time. Therefore, the garbage disposal can be performed during the absence and the running cost can be prevented from being wasted.
