FIG. 3 shows a drive circuit in the garbage disposal apparatus, which includes a control circuit 20 mainly composed of a computer. The control circuit 20 is connected on the input side to an interface 21 and a power supply 22 for receiving the signals of the temperature sensors 11, 18 and the humidity sensor 17 as input signals, and on the output side to the stirring motor 8, heating The heater 9, the exhaust fan 14, the display unit 23, and the modem 24 are connected and have a data extraction terminal 25 for outputting stored data and real-time data to the outside.

The control circuit 20 is provided with an external RAM as a microcomputer in addition to the ROM, and can write and calculate a large amount of data.
It outputs ON / OFF signals of the stirring motor 8, the heater 9, and the exhaust fan 14 based on signals from the humidity sensor 18 and the humidity sensor 17, and outputs a status signal indicating operation or an abnormal state to the display unit 23.

FIG. 4 shows the exhaust humidity by the control circuit 20,
An example of control flow and data accumulation based on the temperature, the heater temperature, and the ON time is shown. The outline of the operation of the garbage processing apparatus will be described with reference to FIG.

When garbage is put into the treatment tank 2 and the lid 3 is closed, the stirring blade 4 rotates to mix the garbage with the culture substrate 19. At this time, the odor and moisture generated in the culture substrate 19 are released to the upper part of the treatment tank 2. Thereafter, the stirring blade 4 is rotated at regular intervals, and the gas is released and fresh air is mixed into the culture substrate 19 every rotation period. The more gas is generated, the more active the decomposition, the higher the temperature and the more water is generated.

This gas is sucked by the exhaust fan 14 and exhausted to the outside. Then, when the temperature of the culture substrate 19 becomes higher than a certain temperature, the temperature sensor 11 attached to the outside of the processing tank 2 measures, and the control circuit 20 turns off the power of the heater 9. When the temperature of the culture substrate 19 is lowered due to poor fermentation decomposition of the culture substrate 19, the control circuit 20 controls the power of the heater 9 to be ON to increase the temperature of the culture substrate 19.

The control operation up to this point can be processed by the conventional technology. In the present invention, it is determined from the state of the rotation waiting period (step S1) of the stirring blade 4 whether or not it is the stirring time in step S2. Then, it is determined that the stirring time has arrived (Yes).
Then, before executing the stirring operation, the temperature of the inner wall surface of the processing tank 2 is measured by the temperature sensor 11 (Step S).
4) It is determined whether or not the currently measured temperature Tn measured at this time is higher than the temperature Tn-1 measured at the time of the previous stirring (step S4).

If it is determined that the current measured temperature Tn> the previous measured temperature Tn-1, the flow advances to step S5 to clear the previously measured temperature data stored in the memory (RAM) and to set the current measured temperature Tn. Tmax is newly stored in the memory, and the process proceeds to step S6 of stirring.

On the other hand, if Tn <Tn-1, the data is not rewritten, and the process proceeds to step S6 of stirring while leaving the previously measured temperature data Tn-1 in the memory. In step S6 of this stirring, the drive of the stirring motor 8 is controlled by the drive of the stirring motor 8 so that the stirring blade 4 is slowly rotated for several minutes via the speed reducer 7. Then, the temperature and humidity Hn of the gas generated during the stirring are measured by temperature and humidity sensors 17 and 18 located before and after the exhaust fan 14.

Then, in the next step S8, the measured humidity Hn is compared with the humidity Hn-
Compare and judge with 1. Current measured humidity Hn> Previous measured humidity Hn
In the case of -1, the process proceeds to step S9, where the memory (RA
The previous measured humidity data stored in M) is cleared and the current measured humidity Hn is newly stored in the memory as Hmax.

On the other hand, if Hn <Hn-1, the data is not rewritten, and the previously measured humidity data Hn-1 is left in the memory, and the process returns to the standby step S1. When the temperature of the culture substrate 19 is lowered due to poor fermentation decomposition or a large amount of water and heat scattering due to latent heat of evaporation, heating of the heater 9 is required to promote activation of fermentation decomposition. Control circuit 2
In the case of 0, the power is turned on and the ON time until the temperature becomes constant is integrated and recorded.

Next, FIG. 5 shows an operation flow of data recording, output and display at regular intervals (for example, 24 hours, every day, etc.). In FIG. 5, the control circuit 20 proceeds from the standby state (step S11) to step S12, and determines whether or not it is a memory write time. The maximum value Tmax of the temperature within 24 hours, the maximum value Hmax of the humidity H, and the heater 9
Is recorded every day (step S).
13).

In this record, while keeping the daily record for the past fixed period (for example, M days), the data before M days is deleted, and the data on the Mth day (the current day) is always newly recorded (step). S13). Therefore, the data stored in step 13 has contents as shown in FIGS. 6 and 7, for example.

In these figures, the daily maximum temperature Tmax, maximum humidity Hmax and ON time of the heater are recorded from day 1 to day M. In the example of FIG.
The maximum temperature Tmax gradually decreases (43 ° C → 31 ° C)
°) and the ON time of the heater 9 is 15 to 70.
Minute and increasing states are shown.

This is because the fermentation decomposition is reduced due to insufficient water, the weight loss of garbage is small, and the amount of generated steam H
Also indicates a reduced dry state. Therefore,
It can be seen that the temperature is lowered as a whole, and the ON time by the heater 9 is relatively long.

If this state is maintained, the temperature does not rise and only the residue continues to increase. The countermeasure to solve this condition is to lower the set temperature of the temperature sensor 11 and lengthen the stirring interval of the stirring blade 6 to prevent the evaporation of water, and to spray 1-2 liters of water all over. is necessary.

In the example of FIG. 7, the temperature Tmax slightly decreases (from 51 ° C. to 40 ° C.), and the heater 9 is turned on.
The state in which the time is greatly increased to 200 to 270 minutes is shown. In this state, there is a portion that has a large amount of water, fermentation decomposition is continued, and a relatively high temperature is maintained, but the temperature decreases due to latent heat of evaporation and the ON time of the heater 9 increases with each stirring. Compared with the dried state of FIG. 6, the temperature Tmax is higher and the state where the ON time of the heater 9 is long continues. This is an overhumid (excessive water) state. If this state continues, the garbage is not decomposed, and the culture substrate 19 itself solidifies in a dumpling shape.

A countermeasure for resolving this state can be taken by increasing the set temperature of the temperature sensor 11 and shortening the stirring interval of the stirring blade 6 to promote the evaporation of water. Furthermore, we will refrain from putting garbage for a while. FIG.
In the actual example, the temperature Tmax decreases to 30 ° C. or less,
A state where the ON time of the heater 9 is as long as 300 minutes or more is shown.

In this state, the garbage is hardly decomposed by fermentation, the weight of the garbage is not reduced, and the temperature does not rise. When this state occurs despite the fact that garbage is being introduced, the culture substrate 19 needs to be replaced.

As is clear from the above description of FIGS. 6 to 8, the phenomena changes of the maximum humidity Hmax and the maximum temperature Tmax are similar, and the change can be captured at the maximum temperature Tmax. It becomes clear at least how the state of the culture substrate 19 has changed.

Returning to the operation flow of FIG. 5 again, the data stored in the RAM is called up under the command of the control circuit 20, and the tables or graphs as shown in FIGS. 23 to clearly show the tendency of the state of the culture substrate 19 (step S1).
4 to S17).

In the operation flow of FIG.
When it is determined “No” in 12, S14 and S16, the process returns to the main flow (step S18). The countermeasure display operation flow shown in FIG. 9 causes the user to take a countermeasure according to the content displayed on the display unit 23. This countermeasure may be displayed at all times, or may be displayed when the lid 3 is opened or closed or by operating an instruction button (not shown).

According to this operation flow, step S2
If the display is determined in steps 2 and 23, it is determined in step S24 whether or not the tendency of the maximum temperature Tmax is high. As a result, if "Yes" is determined, the process proceeds to step S25 in which the ON time of the heater is reduced. It is determined whether it is short. If a conclusion of “Yes” is obtained in this determination, the processing is determined to be good and “display good” is displayed on the display unit 23.

On the other hand, if "No" is determined in the step S25, the process proceeds to a step S27 to display "excess moisture", and then in a step S28, "the input of the raw garbage is set to 2".
In addition, if "No" is determined in step S24 in which it is determined whether the maximum temperature Tmax is high, the process proceeds to step S29 in which it is determined whether the heater ON time is long. If "Yes" is determined, "dry" is displayed and "Please spray 1-2 liters of water" is displayed (step S30,
S31). On the other hand, if “No” is determined in step S29, a display of “degradation of culture substrate” and a display of “Please replace the culture substrate” are performed.

FIG. 10 shows an operation flow in which the display content is communicated to another terminal device by data and displayed on the display unit of the terminal device. In this operation flow, it is determined whether or not to read data in step S41, and if "Yes" is determined, data communication is performed between the garbage processing apparatus according to the present invention and the terminal device (step S42).

In this data communication, a person in charge of a service company or a rental company visits a home or a store where the garbage disposal device is installed, and another information is sent to a data extraction terminal 25 connected to the control circuit 20. This can be done by connecting a terminal device. The maintenance and inspection content data transmitted to the terminal device is displayed on the display screen of the terminal device (step S43,
44) Then, the current situation is explained to the user while showing the contents, and the necessity of inspection and the like are explained.

This data communication is performed by the control circuit 20.
The data extraction terminal 25 and the telephone line can be attached via a modem, and the status of that day or the status of M days can be collectively collected and managed by a service or rental company. Furthermore, it is also possible to connect a garbage disposal device in each home or a store to a personal computer of a service or rental company through a telephone line, and to manage them collectively. By performing such management, it is possible to perform an early grasp of the processing state and an early preparation of the members.
