As is clear from the figure, this microwave absorbing heating element 8 has a polygonal columnar shape, and its cross-sectional shape in the direction perpendicular to its axis is star-shaped.

The operation of this embodiment will be described below.

First, a kitchen waste collector 6 is placed at the drain port of a water tank of a sink in a kitchen, etc., in place of a kitchen waste collector used in a conventional sink, and kitchen waste is poured into this place along with running water and collected. Water is mainly discharged to the drain pipe through the holes, and kitchen waste is drained. When a certain amount of kitchen waste has accumulated, or as needed, remove it from the sink drain. Then, the lid 19 is opened, the garbage collector 6 is mounted inside the cylindrical body 2, and the lid 19 is closed to prevent microwaves from leaking, and then the magnetron 18 is caused to oscillate. The microwave propagates within the waveguide 15, passes through the low dielectric constant heat insulator 5 and the garbage collector 6, and is supplied into the cylindrical body 2 as a metal cavity. The kitchen waste in the kitchen waste collector 6 absorbs microwaves, generates heat, and dries.

On the other hand, the microwave absorbing heating element 8 absorbs microwaves and generates heat. As mentioned above, the microwave absorbing heating element 8
has a ridgeline portion 19 that is parallel to its axis and points outward. Generally, microwaves are concentrated on the sharpened portion, so this ridgeline portion 19 generates heat faster than other portions. Inside the container 6, the kitchen waste surrounds the microwave absorbing heating element 8, and anything that is close to it or in the vicinity receives radiant heat.Moreover, the microwave absorbing heating element 8 is
Since the temperature reaches 0 to 1000°C, the surrounding kitchen waste easily ignites and burns due to this heat.

To promote this combustion, air is introduced into the intake hole 9.10.
．． 11 into the garbage collector 6, and exhaust gas is discharged to the outside through exhaust ducts 15 through exhaust holes 13, 14, and 12.

The amount of kitchen waste that can be stored in the kitchen waste collector 6 installed at the drain port of the water tank is approximately several tens of minutes with a microwave output of 500 to 700 W, although the amount of kitchen waste varies depending on its material, quantity, and amount of water contained in it. When it burns completely, it becomes odorless and harmless ash with a weight ratio of less than 1/100. Note that a catalytic filter is disposed at the exhaust port (by which smoke, odor, and other toxic gases such as No. 2 and Co) can be removed.

When the combustion is completed, the temperature inside the garbage collector 6 decreases, so the change in temperature after combustion is detected using, for example, an infrared sensor or a thermistor, and when the temperature falls below the set value, the magnetron 18 oscillates. Stop the operation.

Then, open the lid 19 and take out the kitchen waste collector 6,
After discarding the ashes, this kitchen waste collector 6 is placed at the drain port part of the sink so that kitchen waste can be collected again.

By controlling the series of kitchen waste incineration operations described above using a microcomputer, kitchen waste can be automatically incinerated.

FIG. 6 shows an example in which a hole for air inflow is provided at the bottom of the garbage collector 6 in the vicinity of the microwave absorbing heating element 8. According to this, when kitchen waste is combusted, an air flow is created along the side surface of the microwave absorbing heating element 8, and the kitchen waste can be combusted more effectively.

Effects of the Invention The kitchen waste processing apparatus of the present invention comprises: a pot-shaped kitchen waste collector having a heating element inside that absorbs microwaves and generates heat; a heat insulating body that holds the kitchen waste collector in a detachable manner; and a heat insulating body. A kitchen waste combustion chamber is constructed with a metal container that houses a kitchen waste collector, and a magnetron is provided to supply microwaves into this combustion chamber, so that kitchen waste can be incinerated in the kitchen whenever kitchen waste is generated. , can be reduced as dust. Since the heating element has a ridgeline on its side surface, the temperature rises in a short time due to microwave irradiation, and the kitchen waste is incinerated. Therefore, it is possible to eliminate rotten kitchen waste from the kitchen, solving hygiene management problems, and eliminating the bad smell caused by it. Since the kitchen waste collector is cleaned every time the kitchen waste is incinerated, it is always kept clean.
