A heat insulating furnace material 102 is pasted on the inner surface of o1, an exhaust port 109 communicating with the outside is provided on the side wall surface of the furnace material 102, and a purifier 110 is connected to the downstream side of the exhaust port 109. The end of the heater 103 is fixed to the inner bottom of the frame 101 so as to protrude inward, and both terminal portions of the heater 103 are fixed to the inner bottom of the frame 101.
protruding outside. Inside the frame 101, a metal processing container 105 is placed on the heater 103. A cylindrical portion that encloses the heater 103 is formed at the bottom of the processing container 105, and an opening is provided in the wall of the cylindrical portion. From this opening, the processing container 105 is

Then, open the lid 104, put in the kitchen waste 106, and ff11
When power was applied to the heater 103 after closing the 04, the kitchen waste 106 was heated and incinerated by the thermal energy of the heater 103, and the generated exhaust gas was purified by the purifier 110 and discharged. How does the device work?

It is controlled by the preset time of a program timer according to the amount of kitchen waste, and first the purifier 110 and the blower 108 are operated to bring the purifier 11 into a fully functional state, and then the heater 103 is operated. After a set time, the heater 103 and the purifier 110 were stopped to complete the incineration process, and then the device was cooled with air, and then the blower 108 was stopped.

Problems to be Solved by the Invention In such a conventional configuration, energy is wasted because the setting time for incineration processing is generally set longer than necessary, and depending on the contents of the kitchen waste, incineration may take a long time. However, there were problems such as complicated operations, such as the device stopping when there was no processing, and there was a risk of erroneous operation. In addition, when temperature detection is used as a method to judge the completion of incineration, for example, there is a method of detecting the atmospheric temperature inside the furnace, but since the combustion state and progress of kitchen waste vary widely, simple methods have poor judgment accuracy and are not effective. The problem was that there was no other way.

The present invention solves the above problems, and aims to provide a kitchen waste processing device that can automatically determine the end of incineration and incinerate kitchen waste in an appropriate time depending on the amount of kitchen waste.

Means for Solving the Problems In order to solve the above problems, the present invention provides a temperature detection means for detecting the temperature of a processing container into which kitchen waste is placed and incinerated.

It is a configuration with.

Effect With this configuration, the temperature of the kitchen waste in the processing container is indirectly detected by the temperature detection means, the time until the temperature of the processing container reaches a predetermined temperature is measured by the time measurement means, and the temperature of the kitchen waste is determined based on this measurement result. Judging the amount by a kitchen waste amount judgment means,
Based on this determination result, the incineration end determining means determines the subsequent heater energization time, and according to the signal from the incineration end determining means, after the determined energizing time, the heater drive means stops energizing the heater, It will automatically start and stop depending on the amount of kitchen waste.

Embodiments Hereinafter, embodiments of the present invention will be explained based on FIGS. 1 to 4. In the figure, a frame 1 is made of a highly heat-resistant material such as metal or ceramic, and its inner surface is lined with an insulating furnace material 2 made of a material such as ceramic fiber that has high heat resistance and has an insulating effect. It has been written. A heater 3 is provided at the inner bottom of the frame 1 for heating kitchen waste 6 that penetrates the furnace material 2 from the outside and projects into the frame 1. Further, a lid 4 that can be opened and closed is provided on the upper part of the frame 1 so that kitchen waste 6 can be put therein. A processing container 6 for processing kitchen waste 6 is disposed above the heater 3, and the processing container 6 has a cylindrical portion with an opening in the wall and envelops the heater 3 at the bottom. It is stored in the processing container 6. Further, on the bottom surface of the frame 1, a temperature detection means 5a such as a thermistor that comes into contact with the processing container at the lower part of the processing container 5 and detects its temperature is provided so as to pass through the frame 1. In addition, an air supply lower is provided on the bottom surface of the frame 1 to allow air to flow into the processing container 6, and a blower 8 provided in communication with this air supply lower sends the air necessary for combustion. ing. In addition, a purifier 1o is provided which communicates with the exhaust port 9 opened in a part of the side wall of the frame body 1 and purifies the exhaust gas by increasing the action of the catalyst 120 using the heating heater 11 to purify the exhaust gas generated by incineration. It is designed to be discharged outside.

The control device 13 includes a time measuring means 14 that inputs the output of the temperature detecting means 6a, a kitchen waste amount determining means 16 that determines the amount of kitchen waste from this measurement time, and an incineration device that determines the subsequent heater energization time based on this determination result. It is comprised of an end determining means 16 and a heater driving means 17 that stops energizing the heater after the energization time has elapsed. Note that 18 is a start switch.

Next, the principle of determining the amount of kitchen waste will be explained with reference to FIG. This method focuses on the fact that if the amount of kitchen waste at that time is small, 70 will be short, and conversely, if the amount of kitchen waste is large, to will be long.

FIG. 3 shows an example of a specific circuit of the main part. Blower 8,
The heater 3 and the purifier 10 are connected to an AC power source via switching means 15a to 15C1 power switches whose on/off is controlled by a control device 13. This control device 13 controls the purifier 1 by a signal from a start switch 18.
switching means 15a to energize o and blower 8;
and turn on 15c. Then, the purifier 1o becomes activated, and air is blown into the frame 1 by the blower 8. After the purifier 10 is sufficiently activated, the switching means 16
Turn on b to heat the heater 3. The processing container 6 contains kitchen waste 6 which is put into the processing container 6 by opening the lid 4 and is strongly heated by the thermal energy of the heater 3. The kitchen waste 6 is then dehydrated, dried, reduced in volume, and then ignited and incinerated. At this time, when the control device 13 determines the completion of incineration based on the temperature signal from the temperature detection means 5a, the switching means 1sb and 15c are turned off to stop the heater 3 and the purifier 10. Thereafter, the blower 8 is operated, and after cooling the device, the switching means 15a is turned off to stop the blower 8, and the process is completed.

Next, the operation of the incineration process of the kitchen waste processing apparatus constructed as described above will be explained using the flowchart shown in FIG. The switching means 15b is turned on, the heater 3 is energized, and the secondary hand is turned on at time t0 shown in FIG. When the temperature of the processing container 5 rises, the temperature data from the temperature detection means 6a is compared with a set value to determine whether it has exceeded a predetermined temperature H shown in FIG. When the predetermined temperature H is exceeded, the measurement of the time amount 〇 is stopped, and the value to at that time is stored. The correlation between this time t0 and the amount of kitchen waste is determined in advance, and the subsequent heater energization time is set based on the amount of kitchen waste. In other words, when the amount of kitchen waste is divided into three stages: (a) When to<T1, there is no amount of kitchen waste, and the power is immediately stopped.(B) When T1<70<T2, the amount of kitchen waste is low. Set time A
When to > T2, the amount of kitchen waste is too high.If you set the power to stop after the set time B, the amount of kitchen waste will be determined and the power will be turned on to the heater after the preset time. For example, after A minutes,
The incineration process is stopped after B minutes, etc., and the incineration process is completed.

Effects of the Invention As described above, according to the present invention, the temperature of kitchen waste in a processing container is detected, the time until the temperature of the processing container reaches a predetermined temperature is measured, and the amount of kitchen waste is determined based on this measurement result. Based on this judgment result, the subsequent heater energization time is determined, and after the determined energization time, the heater is stopped energizing to complete the incineration process, so it can automatically operate according to the amount of kitchen waste. This makes it possible to realize a kitchen waste processing device that is easy to operate and prevents the occurrence of erroneous operations.
