In the figure, reference numeral 4 denotes a correction means 4 for correcting a reference value for comparison with the moisture content determination data.

As shown in FIG. 5, the water content determination data detecting means 2 is constituted by filling a filler 24 with a heater 5 and a thermistor 6 in a case 23. The means 2 is attached to the inner wall surface of the garbage disposal tank 1 so as to contact the garbage disposal material. And
The thermistor 6 detects the temperature before heating by the heater 5 and the temperature after heating for a predetermined time by the heater 5, and obtains a temperature difference between after heating and before heating of the heater 5 as data for determining water content,
The moisture content is determined by comparing the temperature difference, which is the moisture content determination data obtained as described above, by the moisture content determination means 3 with a preset reference temperature. FIG. 4 shows the relationship between the output of the heater 5 and the output of the thermistor (temperature). The temperature difference ΔT between after heating and before heating of the heater 5 is a threshold value Tth when the temperature rises as a reference value.
When ΔT> Tth, a high water content (for example, 65% or more) is determined, and when ΔT ≦ Tth, a low water content (for example, less than 65%) is determined. ing. The timing for determining the moisture content of the garbage processing material by obtaining the data for determining the moisture content caused by the garbage processing material by the water content determination data detecting means 2 and comparing the data with a preset reference value.

The decomposition operation mode of the garbage disposal apparatus 9 includes four operation modes of a strong operation mode, a standard operation mode, a weak operation mode, and a weakest operation mode, and is measured by the data detecting means 2 for determining the water content. The control unit 20 controls the strong operation mode, the standard operation mode, the weak operation mode, and the weakest operation based on the moisture content determination information obtained by comparing the obtained moisture content determination data (the temperature difference) with the reference value (the reference temperature). Operation is controlled by automatically selecting one of the operation modes. Here, the strong operation mode, the standard operation mode, and the weak operation mode are the operation modes of normal garbage disposal, and the weakest operation mode is when no garbage is thrown in, such as when the house is away. Is the operation mode. In the normal operation mode of the garbage disposal, the strong operation mode, the standard operation mode, and the weak operation mode are controlled as shown in Table 1, for example.

[0017]

[Table 1]

When the garbage is thrown in from the inlet 7 with the lid 8 opened, the stirring means 21 is driven to stir and mix the garbage and the garbage disposal material to disperse the garbage in the garbage disposal material.
The garbage is decomposed (fermented) by the action of microorganisms inhabiting the garbage disposal material.

Here, in the present invention, as shown in FIG. 3, when the disassembling processing operation mode immediately before the lid 8 is opened is the weak operation mode or the standard operation mode, the operation mode shifts to the standard operation mode after the lid 8 is opened. If the disassembling process operation mode immediately before the lid 8 is opened is the strong operation mode, the control means 20 controls the operation mode to shift to the strong operation mode after the lid 8 is opened. During the operation in the mode or the strong operation mode, the data for water content determination is detected by the water content determination data detection means 2 and the data for water content determination is preset by the water content determination means 3 by the water content determination means 3. Determine the water content of the garbage processing material by comparing with the reference value,
Based on this determination information, the control means 20 controls to shift to the decomposition processing operation mode corresponding to the water content.

That is, when the lid 8 is opened, the operation is performed in the standard operation mode or the strong operation mode (as shown in FIG. 3, when the lid 8 is opened in the strong operation mode, the operation is performed in the strong operation mode. When the cover 8 is opened in the mode or the weakest operation mode, the operation is performed in the standard operation mode). The temperature difference between after and before the heating of the heater 5 is determined by the water content determination data detecting means 2 for each time, and when the temperature difference exceeds a reference value, the water content is equal to or higher than a predetermined water content (65% in the embodiment). When the water content is determined to be 65% or more in this manner, the operation mode shifts to the standard operation mode. Further, after shifting to the standard operation mode, the number of times that the water content is determined to be 65% or more is 11 times or more in the past 16 times. If there is a strong driving mode If the number of determinations of a water content of 65% or more is less than 11 out of the past 16 times, the mode shifts to the standard operation mode, and further shifts to the standard operation mode. After that, moisture content 6
If the number of determinations of 5% or more is less than 3 out of the past 16 times and a predetermined time (for example, 4 hours and 50 minutes) has elapsed from the determination of the last water content of 65% or more, the mode shifts to the weak operation mode, and After shifting to the operation mode, a certain period of time (for example, 7
If the lid 8 remains closed for 2 hours or more, the control means 20 performs control such that the mode shifts to the weakest operation mode. Note that the determination of the water content is performed by the stirring means 2.
The water content determination data is detected by the water content determination data detecting means 2 at every predetermined number of times of stirring by 1 and the number of determinations by the water content determining means 3 is counted. As the first time, restart counting again and count 16 times.
The above control is performed while repeating resetting.

Here, the water content determination data detecting means 2 has a solid variation such as a solid variation of the temperature rise detected by the water content determining data detecting means 2, and the same moisture content is strong due to the solid variation. There is a tendency that it is easy to go to the driving mode or to the weak driving mode. Here, when the water content determination data detecting means 2 that varies to a lower temperature rise value is used as the water content determination data detecting means 2, the strong operation mode time tends to be long. Conversely, when the moisture content determination data detection means 2 that varies to a higher temperature rise value is used as the moisture content determination data detection means 2, the weak operation mode time tends to be long.

For this reason, in the present invention, correction is performed by the correction means 4 so as to lower the reference value when the strong operation mode having the highest garbage disposal capacity continues for a predetermined time or more without the lid 8 being opened or closed. For example, the correction is performed so that the reference value is reduced by 0.5 °. On the other hand, when the weak operation mode continues for a predetermined time or more in a state where the lid 8 is not opened and closed, the correction unit 4 corrects the reference value so as to increase the reference value. To be corrected. By correcting the reference value in this manner, even if there is an inter-individual variation in the temperature rise value of the water content determination data detecting means 2, the decomposition process operation is performed in an appropriate mode according to the actual water content. Data detection means 2 for water content determination
It is possible to prevent excessive moisture and overdrying caused by the solid dispersion.

In the above-mentioned garbage disposal apparatus, the temperature difference between after heating and before heating of the heater 5 is obtained by the water content determination data detecting means 2 at every predetermined number of times of stirring by the stirring means 21. When stirring by the stirring means 21, the exhaust fan is operated. The heater 5 and the exhaust fan are controlled by duty control. However, if the phase of the output of the heater 5 and the output of the exhaust fan (on / off timing) are the same as shown in FIG. Since a power supply corresponding to the instantaneous maximum power consumption is required, and there is a problem that the size and cost of the apparatus are increased, the output of the heater 5 and the output of the exhaust fan controlled by duty control as shown in FIG. The instantaneous maximum power consumption is reduced by shifting the phase (on / off timing) (for example, the output on / off timing of the heater 5 is delayed by 50% with respect to the output on / off timing of the exhaust fan). This makes it possible to reduce the size and cost of the apparatus.
