Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a kitchen waste processing apparatus that reduces the amount of food waste by incinerating it using microwaves.

BACKGROUND ART Conventionally, this type of kitchen waste processing apparatus has had a configuration as shown in FIGS. 4 and 5. That is, in the main body 1 which is a microwave resonator, there is a garbage processing container 2 equipped with an igniter 2a that generates heat using microwaves.
was placed, and food waste 4 was put into this processing container 2 through an opening 3 provided in the main body 1. This raw garbage 4
is heated and dehydrated by microwaves introduced into the main body 1 from the microwave generator 5 through the supply port 6. Once the dehydration is complete, the temperature rises above the boiling point, resulting in a smoldering state and the production of HC and other substances. Then, the igniter 2a, which is heated by the microwave and becomes red-hot, ignites the fire.
The amount is reduced by incineration and becomes ash. Air necessary for combustion was introduced through an air supply port 7 by a supply air blower 8, and exhaust gas was exhausted through an exhaust port 9 by an exhaust blower 10.

Problems to be Solved by the Invention In such a conventional configuration, even if the next treatment is attempted after one treatment, the ash from the previous treatment remains covering the igniter 2a, making it easy to ignite. This made the incineration process unstable, with longer combustion times and more smoke. Therefore, there was a problem in that the ash had to be discarded after each treatment, and repeated treatments were not possible, which was time-consuming.

The present invention solves these problems,
It is an object of the present invention to provide an easy-to-use kitchen waste processing device that can repeatedly process ash without having to throw away the ash after each process.

Means for Solving the Problem In order to solve this problem, the kitchen waste processing apparatus of the present invention includes a main body which is a microwave resonator, a supply port for introducing microwaves into the main body, and a microwave generator. , an air supply port and an exhaust port provided in the main body, and a processing container for processing kitchen waste that is disposed in the main body and generates heat using microwaves, and the processing container has a hole in the upper part of the ash storage section for dropping ash. The structure includes an igniter that generates heat using microwaves. Moreover, the structure is such that the igniter is provided over the height of the processing container.

Function: With this configuration, food waste is initially placed on the board of the kitchen waste processing container. When the ash is reduced by incineration using microwaves and becomes ash, it does not remain to cover the igniter, but instead falls through the hole in the plate into the ash stock section at the bottom. Further, if the igniter is provided over the height of the processing container, the igniter will not be covered with ash, and ignition and ignition can always be performed stably.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. Note that parts that are the same as those in the conventional configuration are given the same numbers, and their explanations will be omitted.

In the figure, a main body 1 is provided as a microwave resonator in an outer shell 12, and a grating plate 2b and an igniter 2a are provided on the inner bottom of the main body 1 on the top of an ash storage part 2c. A container 2 is placed. Then, a door 11 attached to one side of the main body 1 so as to be openable and closable is opened, and the garbage 4 is put into the garbage processing container 2 through the input port 3. Further, a supply port 6 is opened on the other side of the main body 1, and a microwave generator 5 is provided at the back of a waveguide 6a connected to the supply port 6. An air supply port 7 is provided below the supply port 6 and is connected to an air supply blower 8. Further, the configuration is such that the discharge side of the supply air blower 8 is branched to supply cooling air to the microwave generator 5. The garbage processing container 2 and the grid plate 2b are made of a heat-resistant inorganic sintered body that is transparent to microwaves. The igniter 2a is made of a sintered body of silicon carbide and barium titanate, has heat resistance of 1000° C. or more, and generates heat by absorbing microwaves. An exhaust port 9 is provided on the top surface of the main body 1 and is connected to an exhaust blower 10. Note that each opening of the main body 1, except for the microwave supply port 6, is provided with means for preventing leakage of radio waves.

In the above configuration, the food waste 4 is fed from the input port 3 of the main body 1 onto the grid plate 2b inside the food waste processing container 2. When the microwave generator 5 is energized, microwaves are generated and introduced into the main body 1 through the supply port 6 through the waveguide 6a. The microwave acts on the garbage 4 to heat and dehydrate it. After the dehydration is completed, the garbage 4 heated above the boiling point absorbs microwaves and is ignited by the red-hot igniter 2a, burning and turning into ash. As shown in FIG. 2, the garbage 4 that has become ashes passes between the lattices of the lattice plate 2b and falls to the ash stock section 2c at the bottom. Therefore, after the treatment, ash will not remain covering the igniter 2a. Therefore, even if food waste is subsequently thrown in and processed, the ignition function of the igniter 2a is not impaired, good combustion is possible, and repeated processing is possible without having to throw away the ashes each time. Then, the ash can be discarded when the ash stock portion 2c is filled to near the lattice plate 2b.
Note that air necessary for combustion flows in through an air supply port 7 by a supply air blower 8, and exhaust gas is exhausted from an exhaust port 9 by an exhaust blower 10. Further, even if the garbage 4 turns into ash and becomes zero load, the igniter 2a remains as a load, so the microwave generator 5 is not damaged in the so-called dry state. Further, in this embodiment, a lattice plate is used, but the same effect can be obtained by providing a plate-shaped convex portion in the garbage processing container 2 to support the igniter 2a, as shown in FIG. 3A. In short, it is sufficient that the garbage processing container is provided with a means for temporarily retaining the garbage before it turns into ashes around the igniter.

Next, other embodiments of the present invention will be described.

FIG. 3B shows another embodiment, in which an igniter 2a that generates heat using microwaves is provided almost at the height of the processing container 2. For this reason, even if ash remains after processing garbage, the igniter 2a is always exposed, so that the ignition function can be repeatedly processed without impairing the ignition function.

Effects of the Invention As described above, according to the present invention, the ignition function of the igniter is not impaired even after garbage is processed and turned into ashes, so there is no need to throw away the ashes every time the garbage is processed. Not only does it save you the trouble of throwing it away, but it also has the effect of allowing you to continue processing it over and over again.
