Abstract

PURPOSE:To enable a repetitive processing to be performed without discarding ashes in every processing action by a method wherein a hole for dropping ashes is arranged at an upper part of an ash stock part of a processing container and an igniter for heating with a microwave is arranged. CONSTITUTION:Raw garbage 4 is cast from an inlet port 3 onto a grid plate 2b within a raw garbage processing container 2 and as a micro-wave generating device 5 is energized, a micro-wave is generated, the wave is fed through a wave guide 6a into a main body 1 through a supplying port 6, the micro-wave may act upon the raw garbage 4 to heat and dehydrate it. Upon completion of dehydration, the raw garbage 4 heated over its boiling point may absorb a micro-wave, ignited with an igniter 2a kept red-heated and then made as ashed. The raw garbage 4 converted into ashes passes through between grids of a grid plate 2b and drops onto a lower ash stock 2c. Due to this arrangement, after processing, the ashes are not left on the igniter 2a. Therefore, even if another raw garbage is fed and processed, and igniting function of the igniter 2a is not damaged, a superior combustion is enabled to be performed and so a repetitive processing can be performed without discarding ashes every time a processing is performed.

Description

DETAILED DESCRIPTION OF THE INVENTION 3. Detailed Description of the Invention Field of Industrial Application The present invention relates to a kitchen waste processing apparatus that reduces the amount of food waste by incinerating it using microwaves.

2. Description of the Related Art Conventionally, this type of kitchen waste processing apparatus has been constructed as shown in FIGS. 4 and 5. That is, a garbage processing container 2 equipped with an igniter 2a that generates heat using microwaves is placed inside a main body 1 which is a microwave resonator, and a garbage processing container 2 is placed in the processing container 2 through an opening 3 provided in the main body 1. Garbage 4 was being thrown in.

This raw garbage 4 is heated and dehydrated by microwaves introduced into the main body 1 from a microwave generator 5 through a supply port 6. When the dehydration is completed, the temperature rises above the boiling point, and it becomes smoldering and begins to generate unburned HC. Then, it is ignited by the igniter 2a, which generates heat due to microwaves and becomes red-hot, and is incinerated to reduce its amount to ash. The air necessary for combustion is supplied to the air supply blower 8 through the air supply lower.
The exhaust gas was caused to flow in through the exhaust port 9 and exhausted to the exhaust blower 10 through the exhaust port 9.

Problems to be Solved by the Invention In such a conventional configuration, even if the next process is attempted after one process, the ash from the previous process will not reach the igniter 2.
The incineration process became unstable, as the residue remained covering the a, making it difficult to ignite, prolonging the combustion time, and emitting smoke easily.

Therefore, there is a problem in that the ash cannot be repeatedly processed unless the ash is discarded after each process, which is time-consuming.

The present invention is intended to solve these problems, and aims to provide an easy-to-use kitchen waste processing device that can process ash repeatedly 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 has the following features:
a main body configured as a microwave resonator; a supply port for introducing microwaves into the main body; a microwave generator; an air supply port and an exhaust port provided in the main body; The processing container has a structure in which an igniter that generates heat by microwaves and which is provided with a hole for dropping ash is provided in the upper part of an ash stock section. Furthermore, 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, 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. Also, if you install an igniter along the height of the processing container,
The igniter is not covered in ash and can always ignite and ignite in a stable manner.

EXAMPLE An example 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, the main body 1 has an outer shell 12 as a microwave resonator.
A garbage processing container 2 is disposed at the inner bottom of the main body 1, and is provided with a grid plate 2b and a igniter 2a on the top of an ash stock section 2C. Then, a door 11 attached to one side of the main body 1 so as to be openable and closable is opened, and the raw garbage 4 is put into the raw 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 lower 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 a 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 through the input port 3 of the main body 1 onto the grid plate 2b in the food waste processing container 2. When the microwave generator 6 is energized, microwaves are generated and introduced into the main body 1 through the supply port 6 through the waveguide ea. 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 is
The igniter 2a absorbs microwaves and becomes red hot.
It ignites and burns to ash.

The garbage 4 that has become ashes is placed on a grid plate 2h as shown in Figure 2.
The ash passes through the grid 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, and good combustion is possible, and even if the ash is not thrown away every time it is processed, it is possible to perform a refill process. Then, the ash can be thrown away when the ash stock portion 2c reaches almost the lattice plate 2b. Note that the air necessary for combustion flows in from the supply air lower by the supply air blower 8, and the exhaust gas is exhausted through the exhaust port 9 by the exhaust blower 1°. Further, even if the garbage 4 becomes ash and the load becomes zero, the igniter 2a remains as a load, so the microwave generator 6 is not damaged in the so-called dry state. In addition, in this embodiment, a grid plate is used, but as shown in Fig. 3 B), a plate-shaped convex portion is provided inside the garbage processing container 2 to ignite the igniter 2a.
A similar effect can be achieved by supporting the 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. 3(b) shows another embodiment, in which an igniter 2a that generates heat using microwaves is provided over the height of the grain processing container 2. Therefore, even if ash remains after processing garbage, the igniter 2a is always exposed, so that the ignition function is not impaired and processing can be repeated.

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.
