Abstract

PURPOSE:To protect a microwave generating device from flame and lamp black, by providing a duct, through which microwaves generated by microwave generating device is guided to a feed port, and a blower, generating an airflow in a body through a waveguide. CONSTITUTION:With a microwave generating device 2 energized, microwaves are generated, and is guided into a body 1 through a feed port 4 by means of a waveguide 3. The microwave is exerted directly on garbage 8 to heat it momentarily. Simultaneously, microwaves are also exerted on a heating container 7, and the whole of the heating container 7 is heated. Therefore, the garbage 8 is doubly heated by means of heat, generated by internal heating, and heat from the heat generating container 7 to dehydrate the garbage. Temperature is increased to an ignition point, air incomes through an opening part 5 of the waveguide 3 with the aid of a blower 6, and is fed in the body 1 through the feed port 4 by means of the waveguide 3 for combustion. Though, during combustion, smoke and flame are produced, they are impeded by air exhausted through the waveguide 3, and reversely flow into the waveguide 3 to stop short of the microwave generating device 2, resulting is prevention of adhesion of soot and lamp black to the interior of the waveguide 3.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a kitchen waste processing apparatus for incinerating food waste using microwaves.

2. Description of the Related Art Conventionally, this type of kitchen waste processing apparatus has had the configuration shown in FIG. That is, food waste 3 is put into a heat-generating container 2 that is placed inside a main body 1 that is a microwave resonator and generates heat using microwaves through an opening 10 provided on the side surface of the main body 1, and the microwave generator is activated. The microwave generated from 4A is introduced into the main body 1 through the waveguide aB and the supply port 5, and the garbage 3 is incinerated with heat generated by internal heating of the garbage 3 itself and heat from the heat generating container 2. Air necessary for zero combustion was introduced through an intake port 6 by an intake blower 7, and exhaust gas was exhausted through an exhaust port 8 by an exhaust blower 9.

Problems to be Solved by the Invention In such a conventional configuration, the dehydration of the garbage 3 reaches the antenna section, which may reduce the output of the microwave generator 4A, which is sensitive to heat, or cause damage. There is a problem in that soot, oil, etc. inside may adhere to the inner wall of the waveguide 4B, causing sparks.

The present invention solves these problems and aims to protect a microwave generator from flames and oil smoke.

A heat-generating container that generates heat by microwaves, a supply port that faces into the main body, an exhaust port that discharges air from the main body, and a microwave that generates microwaves. The microwave generator is configured to include a wave generator, a waveguide for guiding microwaves generated from the microwave generator to the supply port, and a blower for generating airflow from the waveguide to the inside of the main body. .

With this configuration, when the blower operates, air flows into the main body from the waveguide through the supply port, which prevents flames and oil smoke from igniting garbage from entering the waveguide from the supply port. , can protect the microwave generator.

Example Hereinafter, one embodiment of the present invention will be described based on FIG.

In the figure, a supply port 4 is provided on the side surface of a main body 1 which is a microwave resonator, and a microwave generator 2 that generates microwaves and the supply port 4 are connected by a waveguide 3. and,
The microwave passes through the waveguide 3 and is introduced into the main body 1 from the supply port 4.

An opening 6 is provided in the wall of this waveguide 3, and a blower 6
One of the discharge sides of is connected. The other end of the blower 6 on the discharge side is connected to the microwave generator 2 for cooling. Further, inside the main body 1, there is disposed a heat generating container 7 which is made of a sintered body of silicon carbide and barium titanate and has a heat resistance of 1000° C. or higher, and generates heat by microwaves. Garbage 8 is thrown into this heat-generating container 7 through an opening 9 of the main body 1. Garbage 8
Exhaust gas generated by combustion is exhausted from the exhaust port 10 through the flue by the exhaust blower 11. It should be noted that each opening of the main body 1, except for the microwave supply port 4, is equipped with means to prevent leakage of radio waves.

In the above configuration, the garbage 8 is stored in the heat generating container 7 and placed into the main body 1 through the opening 9. When the microwave generator 2 is energized, microwaves are generated and the waveguide 3
It is introduced into the main body 1 from the supply port 4 through the inside. The microwave acts directly on the garbage 8 and instantly heats it to the inside.

At the same time, it also acts on the heat generating container 7 to generate heat equivalent to the dielectric loss of barium titanate, which is a ferroelectric material, and the entire heat generating container 7 is heated by silicon carbide, which has good thermal conductivity. Therefore, the garbage 8 is heated and dehydrated by the internal heating and the heat from the heat generating container 7'. When the dehydration is completed, the temperature rises above the boiling point and reaches the ignition point, and the air flows through the opening 5 of the waveguide 3 by the blower 6, passes through the waveguide 3, and enters the main body 1 from the supply port 4. is supplied, and this air is used for combustion. During combustion, smoke and flame are generated, but these are blocked by the air discharged from inside the waveguide 3, and do not flow back through the waveguide 3 and reach the microwave generator 2. 3. No soot or oily smoke builds up inside. The exhaust gas generated by the combustion is exhausted from the exhaust port 1o by the exhaust blower 11.

In this embodiment, the blower is a forced type blower, but it may also be a system in which the inside of the main body 1 is made negative pressure and the air is sucked in from the waveguide 3. In short, the airflow flowing from the waveguide 3 into the main body can be All you have to do is make it happen.

Effects of the Invention As described above, according to the present invention, since air is configured to flow into the main body from the waveguide, it is possible to prevent flames and oil smoke generated by combustion from flowing back into the waveguide, and to reduce heat. Can protect microwave generators that are vulnerable to damage. In addition, it is possible to suppress the phenomenon in which the output of the microwave generator decreases as the temperature rises, and as a result, processing time can be shortened, and
Sparks caused by soot or oily smoke inside the waveguide can also be prevented.
