Description of the Related Art FIG. 8 is a sectional view showing a conventional garbage processing apparatus, in which 2 is a fermenter, 3 is a power plug, 4 is a control unit, 5 is a stirring motor, 12 is a transmission belt, and 6 is a seal. An upper lid 7 to which the material 6a is adhered, a refuse input port 7 for inputting garbage into the fermenter 2 and a door switch 8 for detecting opening and closing of the upper lid 6 are shown.

Reference numeral 9 denotes a stirring blade which is rotated by a stirring motor 5 via a transmission belt 12, reference numeral 10 denotes an intake hole through which air flows in as much as exhausted from an exhaust hole 11, and reference numeral 13 denotes a shutter for opening and closing a residue outlet 14. Reference numeral 15 denotes a residue storage container used when the moisture conditioner 1 is periodically replaced, and reference numeral 35 denotes a detection switch for detecting the presence or absence of the shutter 13.

FIG. 9 is a plan view of an operation panel of a conventional garbage disposal apparatus, in which 24 is an operation panel, 24c is an operation changeover switch, 24d is a stirring lamp indicating that stirring is in progress,
An operation lamp 24e indicates that the vehicle is running.

Next, the operation will be described. Moisture adjuster 1
When an appropriate amount of water is put into the fermenter 2 and the power plug 3 is inserted into the outlet, the operation lamp 24c is turned on, the control unit 4 automatically rotates the stirring motor 5 at a low speed, and the transmission belt 12 9 repeats forward and reverse rotations intermittently for a predetermined time, so that the water and the water conditioner 1 are well mixed and have an appropriate water content. Moisture adjuster 1
Has a decomposing bacterium effective for decomposing organic substances, and starts its activity by obtaining water.

Next, the upper lid 6 is opened, and garbage is introduced from the garbage introduction port 7. When the upper lid 6 is opened and closed, the door switch 8
When a signal is input to the control unit 4 and the stirring motor 5 is rotated, the stirring blade 9 is rotated inside the fermentation tank 2 to mix the garbage and the water conditioner 1. The mixed garbage comes in contact with decomposing bacteria having the water conditioner 1 as a home, and is gradually decomposed to change into water and carbon dioxide.

[0007] Since many of the decomposing bacteria prefer oxygen, it is necessary to supply fresh air of outside air into the fermenter 2. A fresh air is introduced from the intake port 10 to the fermenter 2 and steam, carbon dioxide, and other odorous gas components generated by decomposition through the exhaust port 11 are discharged to the outside of the vessel. An exhaust fan is provided, and the air in the fermenter 2 is replaced by the exhaust fan. In general, when used for several months, the water absorption rate, which is a function of the water conditioner 1, is reduced, and the water conditioner 1 changes to a nodule state. The reason for this is that oil contained in kitchen garbage, fibrous tissues that are difficult to decompose, inorganic substances (nitrogen, phosphoric acid, calcium), etc., cover the outer shell of the water conditioner 1 and that the water conditioner 1 itself is an organic matter. This is because the tissue is destroyed by the decomposing bacteria.

[0008] When the function of the water conditioner 1 is reduced, the number of decomposing bacteria living there is reduced, the decomposition of kitchen garbage is deteriorated, and the reduction rate of kitchen garbage is reduced. It needs to be replaced once. As a guide for the replacement time, the determination is made based on the odor and moisture regulator 1 in the fermenter 2, the color, the bulk, the hardness, and the like. As a replacement method, it is necessary to take out the moisture conditioner 1 containing kitchen wastes into a container, and pull the shutter 13 to open the residue outlet 14 provided at the bottom of the fermenter 2 as shown in FIG. There is a method of allowing the container 15 to fall naturally.

At this time, since the take-out port 14 is open and it is dangerous to put a hand or the like from here, the presence or absence of the shutter 13 is detected by the shutter detection switch 35. Performs control such that the stirring motor 5 is stopped and the stirring blade 9 is not rotated.
Next, after taking out all the water conditioner 1 in the fermenter 2, the shutter 13 is closed, a new water conditioner 1 is put in from the kitchen waste inlet 7, and the operation is restarted. Moisture regulator 1 taken out of the vessel
Can be used as organic fertilizer and kitchen waste is a useful compost.
This is because undecomposed products such as nitrogen, phosphoric acid and calcium are contained.

When the amount of garbage to be processed is large (1 kg as a guide), the operation is changed to "strong" by the operation changeover switch 24c. In addition, the standard amount of kitchen waste (700
g) for "medium" driving, and for even less (approximately 5
00g) performs a manual switching operation for the "weak" operation. The control unit 4 controls the air blowing time and the stirring time by a signal from the operation changeover switch 24c, and the discharged water is set in advance. During the stirring, the stirring lamp 24d is turned on to notify that the stirring is being performed.

[0011]

Since the conventional kitchen waste treatment apparatus is configured as described above, when replacing the moisture control agent 1 containing kitchen waste, the inside of the fermenter 2 is removed from the input port 7 and the amount is adjusted. It is necessary to check the smell, the degree of mass, etc.
Because of the empirical identification, there is a problem that it takes time until identification can be performed.

The present invention has been made in order to solve the above-mentioned problems, and it is possible to notify a replacement time of the water conditioner 1 by a monitor without touching the inside of the fermenter 2 and touch the residue. It is an object of the present invention to provide an easy-to-use kitchen waste disposal apparatus that can automatically fill bags.

A notification lamp is provided, and a maintenance switch for resetting the accumulated time is provided.

The maintenance switch receives a signal from the maintenance switch when the maintenance switch is kept pressed for a predetermined time, and starts the rotation of the stirring blade for removing the residue.

When the upper cover is opened after the maintenance switch signal is received, the control section keeps the stirrer blade in a standby state without rotating the stirrer blade, and closes the upper cover. Then, the standby state is released and the rotation of the stirring blade is started.

Further, a stirring lamp is provided which blinks during the start of rotation of the stirring blade for taking out the residue and which is turned on when the rotation of the stirring blade is started.

Next, the operation during use will be described. First, the control circuit of the kitchen waste disposal apparatus will be described. FIG. 5 is a control block diagram of the garbage processing apparatus, and FIG. 6 is a circuit diagram relating to a stirring motor driving unit. In FIG. 5, the power plug 3
Into the outlet, the first and second door switches 8a,
8b is turned on, the signal from the switch 8 is transmitted to the control unit 4
The control unit 4 controls the stirring motor 5 via the stirring motor driving unit 41, the blow fan 18 via the blow fan control unit 42, the heater 20 via the heater control unit 43, and the maintenance lamp via the monitor control unit 44. The control of 24b and the stirring lamp 24d is started. Further, the control unit 4 counts the accumulated time since the first and second door switches 8a and 8b are turned on when the power plug 3 is inserted into the outlet.

Next, the signals from the first temperature sensor 19 and the second temperature sensor 25 enter the control unit 4 and turn on the heater 20.

When the upper cover 6 is opened, the first door switch 8 is opened.
Then, the second door switch 8b is turned off, the stirring motor 5 is stopped for safety, and the blower fan 18 is turned on to draw air from the inlet 7 into the fermenter 2 so that no odor gas is emitted from the inlet 7. I have to. Upper lid 6
Is closed, the first door switch 8 and the second door switch 8b are turned ON, and the stirring is started again to mix the kitchen waste 17 and the moisture conditioner 1. As described above, the first door switch 8 functions as a substitute switch for inputting / presence / absence / detection of the garbage 17.

The second door switch 8b is a switch for directly turning on and off the 100V power supply line of the stirring motor 5 as shown in the circuit diagram of FIG. ing. This is a double safety circuit that prevents the stirring blade 9 from rotating when the upper lid 6 is opened. The first door switch signal is input to the control unit 4 and is used as a start signal for controlling the temperature and the ventilation assuming that the kitchen garbage 17 has been input. When the stirring blade 9 rotates while the upper lid 6 is open, the rotation of the stirring blade 9 is a high torque, and the second door switch 8
By providing b, even when the control unit 4 malfunctions, the stirring blade 9 does not rotate while the upper lid 6 is open.

In order to raise the temperature of the moisture conditioner 1 due to the generation of fermentation heat during the fermentation of the garbage, the power supply to the heater 20 is stopped when the temperature exceeds a certain temperature monitored by the second temperature sensor 25. When the temperature of the moisture regulator 1 decreases to a certain temperature, the ON / OFF control of the heater 20 by the first temperature sensor 19 is started again. The control by the second temperature sensor 25 aims at an energy saving effect when the fermentation heat rises.

Remove the kitchen waste.

Even if the stirring blade 9 is reversed, the second gear 16
If the number of rotations of a does not exceed a predetermined value within a predetermined time, the power supply to the stirring motor 5 is stopped, and the stirring lamp 24d is turned on and off promptly to remove the kitchen waste 17 caught on the stirring blade 9. When the number of rotations exceeds a certain level, the normal stirring pattern is restored. According to this control, it is possible to prevent damage due to the heat generated by the coil when the stirring motor 5 is locked, and it is possible to reverse the stirring blade 9 to remove a trapped object. Economic effects such as completion are obtained.

Next, the operation will be described with reference to the operation flowchart shown in FIG. First, in step S1,
The water conditioner 1 is put into the fermenter 2, the power plug 3 is inserted into the outlet, and the power is supplied. In step S <b> 2, the heater control is started, and ON-O is performed based on the temperature of the temperature sensor 19.
The FF control is performed, and the heater 20 generates heat to heat the moisture regulator 1. At the same time, in step S3, the stirrer operates to perform intermittent operation in the forward and reverse cycles. In step S4, the operation lamp "medium" is turned on, the speed is reduced while the rotation is transmitted to the reduction gears 16, 16a and 16b by the driving of the stirring motor 5, and the stirring shut 9a rotates in the bearing 26 and is attached to the shaft 9a. The water conditioner 1 is stirred and mixed by the stirring blade 9.

In step S5, the accumulated time from when the power plug 3 is plugged into the outlet is counted by the control section 4. In step S6, when a predetermined time is reached, the maintenance lamp 24b is turned on to perform maintenance for removing the residue. Encourage work. Next, in step S7, the door panel 22 is removed and the dedicated residue storage container 3 is removed.
2 is set on the fixed plate 28 of the fermenter outlet 27 and the shutter 29 is opened. Next, when the maintenance switch 24a is continuously pressed for 3 seconds or more in step S8, the maintenance lamp 24b changes to blinking, and the rotation direction switching relay 47 causes the stirring blade 9 to push up the residue in the direction of the fermenter 2 residue removal port 27. Is rotated for a predetermined time so that the residue is discharged to the residue storage container 32. If the maintenance switch 24a is not pressed for more than three seconds, the normal operation is continued with the maintenance lamp 24b turned on in step S9.

The operation for taking out the residue is such that the maintenance lamp 24b is turned on and the operation is possible within a predetermined time after the operation for taking out the residue.
In step 10, when the accumulated time count does not reach a predetermined time before the maintenance lamp 24b is turned on, the residue is taken out. When the operation switch 24c is pressed for 3 seconds while pressing the maintenance switch 24a in step S11. Then, the operation is forcibly performed after the maintenance lamp 24b is turned on. This operation is mainly used for service personnel, such as when compost is desired on the way, when the fermenter 2 causes abnormal fermentation in the fermenter 2 for some reason, causing odor or stickiness, or when the water conditioner 1 needs to be replaced. Use as

Instead of pressing the maintenance switch 24a and the operation changeover switch 24c for three seconds, which is a predetermined first time, the maintenance switch 24a has a second time longer than the predetermined first time. By pressing the button, the residue can be taken out when the accumulated time count does not reach a predetermined time before the maintenance lamp 24b is turned on.

Next, in step S12, since the maintenance switch 24a is ON, the maintenance lamp 24b is turned on.
Flashes at the same time, the stirring lamp 24d flashes in step S13, and the heater power is turned off in step S14.
And wasteful power is not consumed, and the accumulated time count is reset to zero in step S15.

When the operation is performed on the operation panel 24 (when the maintenance switch 24a is pressed), the operation cannot be performed unless the upper cover 6 is opened, and the stirring motor 5 is prevented from rotating when the upper cover 6 is open. Step S16
Then, it is determined whether or not the upper cover 6 is closed.
While the is open, the agitation lamp 24d blinks in step S17 to notify the standby state.

If the upper lid 6 is closed, the process proceeds to step S18, in which the door switches 8, 8b are turned on to rotate the stirring motor 5 in a predetermined direction for a predetermined time and to turn on the stirring lamp 24d in step S19. And notify that discharge is in progress. In step S20, if the upper lid 6 is opened halfway, the process proceeds to step S21.
Then, the stirring is stopped, the stirring lamp 24d flashes, and the apparatus enters a standby state. The time during this period (opening time of the upper lid) is not added to the predetermined time.

In step S22, the stirring time is counted, and a predetermined time (for example, 5 minutes for the first time,
When the stirring is performed (three minutes after the first blade), the removal of the residue is completed in step S23, the maintenance lamp 24b and the stirring lamp 24d are turned off in step S24, and the completion of the removal operation is notified. However, if the residue cannot be sufficiently discharged, step S
Retry at 25 and return to step S8 for maintenance switch 2.
4a is pressed for 3 seconds as in the first time, and the maintenance control is performed again. However, since it can be estimated that the residue in the fermenter 2 is smaller than the first time after the second time, the stirring time is set shorter than the first time, and the retry is accepted for 10 minutes after the end of the first maintenance operation (after the maintenance lamp 24b is turned off). Is set to within. This is for automatically returning to the normal operation mode. If there is no residue in the fermenter 2 after opening the upper lid 6, step S
Without retrying at 25, the residue storage container 32 is removed at step S26. At this time, the shutter 29 moves in conjunction with the residue storage container 32 and closes the take-out port 27.

Next, at step S27, the maintenance lamp 24
b Count the time after turning off the light, and after 10 minutes, step S2
At 8, the normal operation mode is set. In step S4,
The moisture regulator 1 receives the heat of the wall surface of the fermenter 2 and is evenly heated. When the heater 20 is energized, the control unit 4 receives the resistance value conversion of the first temperature sensor 19 and turns on and off.
It is controlled to keep the heater surface at a predetermined temperature. When the upper lid 6 is opened and an appropriate amount of garbage is put in from the garbage input port 7, as shown in the following equation, the fermenter 2 is gradually circulated by the decomposing bacteria carried on the water conditioner 1 to form water and dioxide. Change to carbon. Cm (H ₂ O) n + mO ₂ → mCO ₂ + nH ₂ O Carbohydrate Oxygen Carbon dioxide Water

Further, the blower fan 18 is turned on intermittently in order to discharge steam (water), carbon dioxide, and various gases generated by the decomposition to the outside of the device. At this time, when the air in the fermentation tank 2 is exhausted from the exhaust port 11, fresh air outside the vessel flows into the fermentation tank 2 through the intake port 10 to supply oxygen to the decomposing bacteria. Since the decomposing bacteria mainly have an aerobic characteristic and are activated by obtaining oxygen, the stirring and the blower fan 18 are intermittently controlled so that the inside of the fermenter 2 is not deprived of oxygen. Further, the water is reduced by the weight of the water discharged to the outside by the blower fan 18. However, if the amount of the discharged water is large, the water content of the water regulator 1 is too low, and the activation of the decomposing bacteria is hindered. Agent 1
The conditions such as the stirring time, the evacuation time, and the temperature are controlled so that the water content becomes 40 to 60%.

The kitchen waste treatment apparatus according to the present embodiment repeatedly puts and treats the kitchen waste 17, but the water conditioning agent 1 is deteriorated, decomposed, impregnated with hardly decomposed substances (oil, inorganic substances) and the like. , The function of maintaining the water content gradually decreases, and the role of the moisture regulator 1 is lost. As a result, the oxygen supply conditions to the decomposing bacteria are reduced and the activity of the decomposing bacteria is inhibited, so that the decomposing power of the garbage is reduced and the undecomposed garbage is increased, and at the same time, the odorous gas (ammonia, amine, Hydrogen sulfide) generation also increases. Generally, depending on the type of the garbage 17 to be thrown in, it usually takes 2 to 3 months, and it is necessary to periodically replace the water conditioner 1 in order to maintain the decomposition power.

In step S6, the replacement time of the moisture conditioner 1 is estimated from the experimental value during the operation time, and the maintenance lamp 24b is turned on in the safe direction of the minimum value to notify the replacement time. Since the inside of the processing tank is maintained at 30 ° C. or higher by the heater 20 in the present machine, a stable decomposition is given with a small variation in the decomposing power against a change in the outside air temperature due to the season. good. In addition, the operation mode is changed to "strong" when the input amount is large, "medium" for the standard amount, and "low" when the input amount is small so that the decomposition is performed smoothly even if the input amount of the garbage 17 is different. Since the control pattern is selectable and the stirring frequency, the evacuation time, the temperature control, and the like are changed to create a control pattern suitable for the amount, the estimation accuracy at the time of replacement is improved.

In step S26, the residue container 32
The residue taken out is reusable as compost and contains many fertilizer components such as nitrogen, phosphoric acid and calcium. If not reused, the entire container can be discarded as combustible waste.
