Further, the moisture content prediction processing unit 41 is connected to the abnormality output display unit 65 via the abnormality processing unit 63 so that the abnormality state of the kitchen waste processing apparatus can be displayed on the abnormality output display unit 65. .

In the kitchen waste processing apparatus configured as described above, the detection block portion 16 including the heating temperature detecting device 17 and the heating device 18 includes the joining portion 24 and the contact portion 2.
5, that is, the processing tank 1 is in close contact with the processing tank 1 through the bonding contact portion 27, and the processing tank 1 is made of a material having low thermal conductivity such as stainless steel or polymer resin, that is, a material having poor thermal conductivity. Therefore, the heating temperature detection device 17 can accurately detect the temperature of the sawdust 14 in the processing tank 1, and the heating device 18 can efficiently heat the sawdust 14.

That is, since the processing tank 1 is made of a material having a low thermal conductivity, the heat from the heating device 18, more specifically, the heat of the detection block portion 16 heated by the heating device 18, is stored in the processing tank 1. Since the heat is merely diffused only to the vicinity of the joint portion 24, the heat is conducted to the sawdust 14 near the contact portion 25, and the heat is dissipated from the sawdust 14 near the contact portion 25 to the sawdust 14 other than near the contact portion 25. To be On the contrary, the temperature of the sawdust 14 is efficiently transmitted to the detection block portion 16 by the same principle, and can be accurately detected by the heating temperature detection device 17.

When the heat of the detection block 16 heated by the heating device 18 is sufficiently conducted to the sawdust 14 in this way, when the moisture content in the sawdust 14 is small, the sawdust 14
The heat conduction to the sawdust 14 is high, and the temperature of the sawdust 14 detected by the heating temperature detecting device 17 is high. When the moisture content in the sawdust 14 is high, the heat conduction to the sawdust 14 is large and the heating temperature detecting device 17 The detection temperature becomes low.

Contrary to the above-mentioned heat conduction, the case where the processing tank 1 is made of a material having a high thermal conductivity will be described more specifically. The processing tank 1 has a high thermal conductivity such as aluminum or copper. In the case where the sawdust 1 is made of a heat-resistant material, the heat of the detection block portion 16 heated by the heating device 18 is diffused into the entire processing tank 1 so that the sawdust 1
Since the heat is conducted to the whole of 4, the heat dissipation of the sawdust 14 cannot be obtained in the vicinity of the contact portion 25. Even when the moisture content in the sawdust 14 is low or high, the temperature change detected by the heating temperature detector 17 is small and the moisture rate of the sawdust 14 cannot be detected.

As can be seen from the above description, the heating temperature detecting device 17 constituting the detection block 16 heats the sawdust 14 in the processing tank 1, and the heating device 18 detects the temperature of the sawdust 14 when heated. By doing so, the moisture content in the sawdust 14 can be detected, and this relationship will be described more clearly with reference to FIG.

In FIG. 5, the horizontal axis shows the heating time when the sawdust 14 is heated by the heating device 18, and the vertical axis shows the temperature of the sawdust 14 detected by the heating temperature detecting device 17, which corresponds to the heating time. It is a graph which took temperature the moisture content of the sawdust 14 as a parameter. As shown in the figure, the moisture content of the sawdust 14 is shown for the cases of 0%, 20%, 40%, and 60%, but the heating time and the temperature are proportional to each other, and the heating time By detecting the temperature and the temperature, the moisture content can be clearly known. That is, for example, when the heating time is 5 minutes, the moisture content is 0% when the temperature of the sawdust 14 is 14 ° C., the moisture content is 20% when the temperature is 12 ° C., and the moisture content is 11 ° C. It can be seen that the water content is 40% and the water content is 60% at 10 ° C.

As described above, the water content of the sawdust 14 is
It can be detected from the heating time by the heating device 18 and the temperature detected by the heating temperature detecting device 17, but this moisture content also changes depending on the outside air temperature detected by the outside air temperature detector 23 as shown in FIG. .

Similar to FIG. 5, FIG. 6 is a graph showing that the temperature characteristic with respect to the heating time changes depending on the outside air temperature. In this graph, the moisture content is fixed at 40%. There is. In FIG. 6, the outside air temperature is 1
Although cases of 0 ° C., 25 ° C., and 40 ° C. are shown, it can be seen that the temperature with respect to the heating time is affected by the outside air temperature, and the higher the outside air temperature, the higher the temperature for the same heating time.

Therefore, as shown in FIG.
When the moisture content is detected by the heating temperature detection device 17, it is necessary to correct the moisture content according to the outside air temperature detected by the outside air temperature detector 23 as shown in FIG.

Further, FIG. 7 shows that the temperature for the same heating time as in FIG. 5 is influenced by the temperature of the processing bath 1 detected by the bath temperature detector 22, that is, the bath temperature. As can be seen from the figure, the temperature with respect to the heating time increases and changes almost in the same manner as the temperature inside the tank changes. Therefore, as shown in FIG.
The water content detected by the heating temperature detecting device 17 also needs to be corrected by the in-tank temperature detected by the in-tank temperature detector 22.

FIG. 8 is a graph showing the temperature with respect to the heating time when the heating power and the moisture content are used as parameters. When the heating power is small, the temperature change with the heating time is small and the heating power is large. In this case, it can be seen that the change in temperature with respect to the heating time is large.

As can be seen from the above description, the detection block section 16 composed of the heating temperature detecting device 17 and the heating device 18 constitutes a moisture content sensor for detecting the moisture content, and the in-tank temperature detector 22 and the outside temperature detector 22. The air temperature detector 23 constitutes a correction means for correcting the water content detected by the water content sensor.

Next, the operation of the kitchen waste processing apparatus configured as described above will be described with reference to the flowcharts shown in FIGS. 9 and 10.

In the processing shown in FIGS. 9 and 10, the garbage processing device has a ZERO (zero) point correction reading mode and a normal reading mode. The ZERO point correction reading mode is for detecting and storing the state where the sawdust 14 is not contained in the processing tank 1, that is, the state of the water content sensor when the water content is 0%, and the normal reading mode is for the processing tank 1 Sawdust inside 14
And the water content in the state that the garbage is contained. In addition, the ZERO point correction reading mode is performed at the time of shipping inspection of the kitchen waste processing apparatus at the factory.

In the processing shown in FIGS. 9 and 10, first, when the power of the kitchen waste processing apparatus is turned on, the hard reset is released and the soft reset processing is executed (step 1).
00). When the soft reset process is executed, ZERO
It is checked whether the mode is the point correction reading mode or the normal reading mode (steps 101 and 102). In the normal read mode, the normal control of step 122 is performed, but in the initial state when the power is turned on, the ZER is first set.
Since the mode is the O point correction reading mode, the process proceeds to step 103 and subsequent steps, and preprocessing for reading the moisture content sensor is performed in steps 104, 105, 106 and 107.

That is, at step 104, the temperature inside the processing tank 1 is detected by the temperature inside the processing tank 22, and the detected temperature inside the processing tank 1 is stored in the inside temperature storage unit 53. Then, it is checked whether or not the detected and stored temperature in the processing tank 1 is normal (step 1
05). When the temperature in the processing tank 1 is normal, the outside air temperature is detected by the outside air temperature detector 23 and stored in the outside air temperature storage unit 55. Whether the detected outside air temperature is normal or not is determined. Checked (steps 106, 1)
07). When the outside air temperature is normal, the moisture content is detected and stored by the moisture content sensor composed of the heating temperature detection device 17 and the heating device 18 constituting the detection block unit 16 as described above. It is checked whether the moisture content is normal (step 10).
8, 109).

When the moisture content thus detected and stored is normal, heating power is supplied to the heating device 18 through the heating power output section 49 under the control of the moisture content prediction processing section 41. When the heating power is supplied, it is checked whether or not the moisture content sensor reading timer is counting (steps 110 and 111). If the moisture content sensor reading timer has not timed, the moisture content sensor reading timer is set and the time counting is started (step 112). In addition, when the moisture content sensor reading timer is counting, the heating power for the heating device 18 is detected and stored by the heating power detector 51, and it is checked whether the detected and stored heating power is normal. (Steps 113 and 114).

When the detected and stored heating power is normal, the temperature of the moisture content sensor is read and stored (step 115). Then, the moisture content is predicted in the moisture content prediction processing unit 41 based on the temperature of the processing tank 1 already read and stored, the outside air temperature, and the temperature of the moisture content sensor (step 116). When the moisture content is predicted in this way, it is checked whether or not the moisture content sensor reading timer has elapsed for 5 minutes (steps 134 and 135).

If the moisture content sensor reading timer has not elapsed for 5 minutes, the process proceeds to step 122 and thereafter, but if it has elapsed for 5 minutes, the moisture content is determined in the moisture content determination processing unit 43, and ZERO is set. It is checked whether or not it is the point correction reading mode, that is, whether it is the ZERO point correction reading mode or the normal reading mode (steps 117 and 118).

In the check in step 118, ZE
If it is the RO point correction reading mode, step 117
It is checked whether or not the ZERO point corrected water content determined in step 3 is normal (steps 119 and 120). If it is normal, it is stored as the ZERO point corrected water content (step 121) and the process proceeds to step 132. Further, in the check in step 118, if the normal reading mode is set, the normal moisture content is stored (step 12).
3) and then the process proceeds to step 132.

As described above, the moisture content is determined and the ZE
When the RO point correction moisture content is stored (step 121) and the normal moisture content is stored (step 123), and the process proceeds to step 132, the moisture content sensor reading prohibition flag is set in order to prohibit reading of the moisture content sensor for a certain period. Is set, the moisture content sensor reading prohibition timer starts counting time (step 132), and then the process proceeds to step 122. Then, when the moisture content sensor read prohibition timer completes timekeeping, the moisture content sensor read prohibition flag is cleared (step 122d), the process returns to step 101, and Z is returned.
The process is repeated from the check whether the ERO point correction reading mode is set or not.

When the moisture content sensor reading timer starts counting, the progress is checked every 30 seconds in the normal control moisture content reading timer event (step 122b). If an elapsed event occurs, the process proceeds to step 103. Returning to this, the process of reading the moisture content sensor shifts to the process of detecting and storing the temperature in the processing tank 1, and in the normal control, as described above, the temperature of the processing tank 1 is detected and stored and checked by the in-tank temperature detector 22 (step). 104, 105), detection and storage of the outside air temperature by the outside air temperature detector 23 (steps 106, 107), detection and storage and check of the moisture content by the moisture content sensor (steps 108, 10).
9), supply of heating power and check of moisture content sensor reading timer, counting and start (step 110,
111, 112), storage and check of heating power (steps 113 and 114), detection and storage of temperature of moisture content sensor (step 115), prediction and determination of moisture content (steps 116 and 117), and storage of moisture content (steps 116 and 117). After step 123) and the like are performed, and after the process of step 132 is performed, the normal control of step 122 is performed based on the detected and stored and determined moisture content, and based on the detected and stored and determined moisture content. Normal control is repeatedly performed.

In this normal control, controls 1, 2, 3, 4 based on the moisture content are performed based on the determined moisture content (steps 122e, 122f, 122g, 122).
h).

The controls 1, 2, 3, 4 based on this moisture content are
As shown below, the control is performed based on each moisture content, and each control 1, 2, 3, 4 is the moisture content at which the kitchen waste thrown into the sawdust 14 is fermented and decomposed most efficiently for the corresponding moisture content. The stirring motor 10 and the heater 1

Moisture content = 10-30%: Control by moisture content 1 Moisture content = 30-50%: Control by moisture content 2 Moisture content = 50-99%: Control by moisture content 3 Moisture content = 10% or less and 99% or more: control by moisture content 4 Further, in the above repetitive processing, the moisture content sensor reading timer obtains the determined moisture content every 30 seconds and the moisture content after 5 minutes has been determined. In the process, a moisture content determination process is performed based on the plurality of moisture contents obtained repeatedly every 30 seconds. In this finalizing process, the final moisture percentage is calculated by averaging the plurality of moisture percentages or obtaining the ratio.

When the moisture content sensor read inhibit timer starts counting, the moisture content read inhibit timer event (122c) in the normal control (step 122) is used to check the completion of the clocking. The rate sensor read prohibition flag is cleared (step 122
d) Returning to step 101, the moisture content sensor reading process shifts to a reading mode check process as to whether or not it is the ZERO point correction reading mode.

When the temperature inside the processing tank 1 is abnormal in the check of the inside temperature of the processing tank 1 at step 105, an abnormal temperature reading temperature inside the processing tank is set (step 124). Further, when the outside air temperature is abnormal in the check of the outside air temperature in step 107, the outside air temperature abnormality flag is set (step 125). Further, in the moisture content check in step 109, if the moisture content is abnormal, the moisture content sensor reading abnormality flag is set (step 126). Further, in the heating power check in step 114, if the heating power is abnormal, the heating power reading abnormality flag is set (step 127). Further, in the check of the ZERO point corrected water content in step 120, if the ZERO point corrected water content is abnormal, the ZERO point corrected water content abnormality flag is set (step 133).

Steps 124, 125, 12 described above

When each of the point correction moisture content abnormality flags (step 133) is set, abnormality processing is performed (step 128), the heating power to the heating device 18 is stopped, and whether or not this heating power stop processing has occurred three times. Is checked (steps 129 and 130). When it occurs three times in succession, it is determined that there is an abnormality such as the reading of the moisture content sensor, and an abnormality display such as the reading of the moisture content sensor is controlled by the moisture content prediction processing unit 41 and the abnormality output display unit 65 is output via the abnormality processing unit 63.
