Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposal device that incinerates garbage by microwave.

2. Description of the Related Art Generally, as for the garbage treatment equipment, there are those that burn with gas, those that crush and compress, and those that ferment, but these are all due to noise, foul odor, and the extent of weight loss. It was unsuitable for use in the home kitchen.
Therefore, the inventors have considered a garbage processing device using microwaves. Hereinafter, this garbage processing device will be described with reference to FIG. In the figure, a main body 1 which is a microwave resonator
A bottomed cylindrical heat generating container 2 that generates heat with microwaves was disposed inside, and raw garbage 4 was charged into the heat generating container 2 through a charging port 3 provided on the side surface of the main body 1. Then, the garbage 4 and the heat generating container 2 are heated by the microwave introduced from the microwave generator 5 into the main body 1 through the supply port 6. That is, the garbage 4 is incinerated and reduced by the heat of its own internal heating and the heat from the heat generating container 2, and the air required for combustion is introduced by the air supply blower 8 through the air supply port 7. Further, the exhaust gas generated by the combustion is exhausted by the exhaust blower 10 through the exhaust port 9.

However, in such a configuration, the heating container 2 has a bottomed cylindrical shape in order to enhance the heating effect and the heating uniformity of the garbage 4. However, there is a problem in that the amount of oxygen is insufficiently supplied, unburned HC is frequently generated, which causes odor and smoke, and the apparatus becomes large in scale even when purifying exhaust gas.

The present invention solves such a problem, and an object of the present invention is to improve the combustion in the heat generating container and suppress the generation of unburned HC.

Means for Solving the Problems In order to explain this problem, the garbage processing device of the present invention is
A body that is a microwave resonator, a supply port that introduces microwaves into the body, a microwave generator that supplies microwaves to the supply port, and a bottomed bottom that is placed inside the body and has an open top surface. It is cylindrical and has a heat generating container that generates heat by microwaves, an air supply port that allows air to flow into the main body, and an exhaust port that discharges gas in the main body, and the heat generating container has an opening on its side surface. It is the configuration provided.

Operation With this configuration, when raw garbage burns in the heat generating container, air flows from the opening of the heat generating container into the heat generating container, oxygen can be effectively supplied to the burning raw garbage, and the combustion state is improved. can do.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. In the figure, a microwave is introduced into a main body 101, which is a microwave resonator, and a waveguide 103 and a supply port
A magnetron device 102, which is a microwave generator that radiates via 4 is provided. The blower 105 cools the magnetron device 102 and causes air to flow into the main body 101 through the air supply port 106. Inside the main body 101, a heating container 107 having a bottomed cylindrical shape having an open top surface made of a sintered body of silicon carbide and barium titanate and having heat resistance of 1000 ° C. or higher is arranged. An opening 107a is provided on the side surface of the heat generating container 107. Garbage 108 is put into the heat generating container 107 through the inlet 109 provided on the side surface of the main body 101.
It is thrown in. Exhaust gas generated in the main body 101 is exhausted by an exhaust blower 111 from an exhaust port 110 through a flue. It should be noted that each opening of the main body 1 is provided with means for preventing electric wave leakage except for the microwave supply port 4.

In the above configuration, the garbage 108 is thrown into the heat generating container 107 in the main body 101 through the charging port 109. When the magnetron device 102 is energized, microwaves are generated,
It is introduced into the main body 101 through the supply port 104 through the inside of the waveguide 103. The microwave directly acts on the garbage 108 and instantly heats the inside. At the same time, it acts on the heat generating container 107 to generate heat corresponding to the dielectric loss of the barium titanate which is a ferroelectric substance, and the whole heat generating container 107 is heated by silicon carbide having a high thermal conductivity. Therefore, the garbage 108
Is double heated by the heat from the internal heating and the heat from the heat generating container 107 to be dehydrated. When dehydration ends, the temperature rises above the boiling point, reaches the ignition point, and starts combustion. At this time, since the opening 107a is provided on the side surface of the heat generating container 107, a flow of air flowing into the heat generating container 107 through the opening 107a is generated, and the raw garbage 1 to be burned 1
Oxygen can be effectively supplied to 08, and the combustion state in the container 107 is improved. As a result, it is possible to suppress the generation of unburned HC that causes odor and smoke. Also, when purifying exhaust gas, it is possible to reduce the capacity of the device and rationalize the manufacturing cost. On the other hand, as for the garbage 108, as shown in FIG.
At the end of dehydration, the volume is reduced so that it collects in the center of the bottom, and the volume becomes 1/4 or less. When it burns to ash, it remains only slightly on the bottom. Therefore, if the opening 107a is provided near the height of the garbage at the end of dehydration, the combustion can be effectively improved without spilling ash to the outside of the container 107. The air necessary for combustion flows into the main body 101 from the air supply port 106 by the blower 105, and the exhaust gas generated by combustion is exhausted by the exhaust air blow 111 from the exhaust port 110.

EFFECTS OF THE INVENTION As described above, according to the present invention, since the opening is provided on the side surface of the bottomed cylindrical heating container having the top surface opened, the container is heated while maintaining the heating effect of garbage and the uniformity of heating. Oxygen can be effectively supplied to the inside, and combustion can be improved. Since the generation of unburned HC is suppressed, it is possible to provide a device with less odor and smoke, and when purifying exhaust gas, the manufacturing cost of the device can be rationalized.
