Abstract

PURPOSE:To incinerate garbage without hindrance even when a large amount of the garbage is brought in by a method wherein the inside of a cup-shaped garbage collector is divided with partition walls and through-holes are formed at the walls and a microwave absorbing and heating element is installed in one section of the garbage collector. CONSTITUTION:Garbage thrown in is collected in each section divided with partition walls 12 of a cup-shaped garbage collector 11. At the time when drying is almost completed by the irradiation with microwaves a microwave absorbing and heating element 14 installed in one division of the collector 11 absorbs also the microwaves and generates heat and reaches a temp. of about 700-900 deg.C. Thereby, the garbage placed in the section where the element 14 is installed starts to burn earlier than the garbage placed in the other section. Since through-holes 13 are formed at the lower part of the walls 12, flames enter adjacent other sections through the holes 13 at the walls 12 as combustion progresses and the flames ignite the garbage in the sections. The degree of combustion is not excessively intensive for the amount of the garbage and the combustion can be kept stable.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a kitchen waste disposal device for incinerating kitchen waste (garbage) generated in a kitchen.

Conventional technology To dispose of kitchen waste generated in a home or commercial kitchen, the kitchen waste is poured into a mesh-shaped kitchen waste storage compartment installed at the drain of the water tank in the kitchen sink along with running water, allowing it to naturally dehydrate for a while. Generally, the garbage is placed in plastic bags or the like and stored in a kitchen waste storage cabinet, and on the designated garbage collection day, the bags are taken to a common collection site for collection and disposal.

However, in this method, the kitchen waste rots by the time the garbage is collected, which not only produces a bad odor but is also unsanitary.

As a device capable of solving this problem, the applicant has developed a kitchen waste processing device that irradiates kitchen waste with microwaves to dry and incinerate the kitchen waste (for example, Japanese Patent Application No. 147356/1982). This kitchen waste processing device can easily incinerate a predetermined amount of scraps such as leftover food, vegetables, and fruits.

Problems to be Solved by the Invention With this device, it is possible to incinerate the amount of kitchen waste that is generated on a daily basis in a general household very easily and quickly. However, a large amount of kitchen waste may be generated unexpectedly, and it may be necessary to incinerate it all at once. In this case, a large amount of dry kitchen waste is ignited all at once by microwave irradiation, which not only causes extremely violent and unstable combustion, but also makes it impossible to ensure sufficient safety. There is a risk that it will disappear. Furthermore, since a large amount of exhaust gas is generated, it is conceivable that the purifying ability of the catalyst is exceeded and the exhaust gas cannot be purified sufficiently.

The present invention aims to solve such problems by providing a kitchen waste processing device that can incinerate the waste without any problem even when a larger amount of kitchen waste is generated than normally expected.

Means for Solving the Problems In the kitchen waste processing apparatus of the present invention, the inside of the pot-shaped kitchen waste collector is divided by one or more partition walls, and a through hole is provided in the partition wall. A microwave absorbing heating element is placed in one divided area.

Effect: With this configuration, the kitchen waste in the kitchen waste collector is not only dried almost evenly by receiving microwaves, but also heated by the self-heating of the microwave-absorbing heating element installed in one section of the kitchen waste collector. ignite and burn.

The heat insulator 4 is made of a heat-resistant material that transmits microwaves, such as alumina or ceramic. Of course, it is not limited to a layered body, but may be a cylindrical body that can be mounted inside the cylindrical holder 3. Reference numeral 5 designates an intake port, and 6 designates an exhaust port, which are provided in the lower and upper portions of the cylindrical body 3, respectively. These are constructed by forming small holes through them that are large enough to prevent leakage of microwaves. Of course, this may be in the form of a mesh having a mesh size that prevents microwaves from leaking out. 7 is an exhaust duct, one end of which is connected to the exhaust port 6 of the cylindrical holder 3.

Reference numeral 8 denotes a waveguide, one end of which is connected to the opening 9 of the cylindrical holder 3, and a magnetron 10 attached to the other end. Reference numeral 11 denotes a pot-shaped kitchen waste collector, which is made of a heat-resistant, low dielectric constant material such as alumina or ceramic.
It is attached to and rotatably arranged. This holds the kitchen waste and also temporarily holds the dust until it is finished burning.

The inside of the pot-shaped kitchen waste collector 11 is divided into a plurality of rooms by partition walls 12, as shown in FIGS. 2 and 3.

A plurality of through holes 13 are bored in the lower part of the partition wall 12. Reference numeral 14 is a microwave absorbing heat generating element, which is protruded into one section of the pot-shaped garbage collector 11. This is made of a heat-resistant, high-permittivity material such as silicon carbide that absorbs microwaves and generates heat, and when irradiated with microwaves, the temperature rises to approximately 700 to 900°C and generates heat.

Reference numeral 15 denotes a chisel, which is connected to the rotary shaft 12 for rotating the pot-shaped garbage collector 11. Reference numeral 16 denotes a dust chute, which is attached to the lower opening of the cylindrical holder 3, and further supports both ends of the rotating shaft 12. A shielding plate 17 is rotatably attached to the lower opening of the ash jute 16, and is closed when the magnetron 10 is in operation to prevent microwaves from leaking to the outside. Reference numeral 18 denotes an ash storage container, which is disposed below the ash chute 16 and is attached to the lower opening of the housing 1 so that it can be pulled out.

In this device, a housing 1, a cylindrical holder 3, a heat insulator 4
The pot-shaped kitchen waste collector 11 constitutes a kitchen waste incineration chamber.

Next, the operation of this embodiment will be described.

First, open the lid 2, put kitchen waste in it, and then close it. The thrown kitchen waste is accumulated in each compartment divided by the partition wall 3 of the pot-shaped kitchen waste collector 11. Next, when the power supply operation unit (not shown) is activated to cause the magnetron 10 to oscillate, the microwave propagates through the waveguide 8 and passes through the heat insulator 4 through the opening 9 of the cylindrical holder 3. , is guided into the cylindrical holder 3, and is irradiated onto the kitchen waste inside the pot-shaped kitchen waste collector 11. With this microwave irradiation, firstly, the water contained in the kitchen waste absorbs the microwave energy, generates heat, evaporates, and dries the kitchen waste. When the drying of kitchen waste is almost completed, the microwave absorbing heating element 14 provided in one section of the pot-shaped kitchen waste collector 11 also absorbs microwaves and generates heat, and the temperature reaches about 700 to 900°C. become.

As a result, the kitchen waste in the compartment where the microwave absorption heating element 14 of the pot-shaped kitchen waste collector 11 is arranged starts to burn before the kitchen waste in other compartments. Since the partition wall 12 is formed with a through hole 13 at its lower part, the kitchen waste in this section is primarily burned at first, and as the combustion progresses, the flame from the combustion in the section is passed through the through hole 13 of the partition wall 12.
It penetrates into another adjacent compartment and ignites the kitchen waste in that compartment. In this way, the incineration of kitchen waste is transferred from one section of the microwave absorption heating element 14 to another section adjacent to it (so that the degree of combustion is not excessively large relative to the amount of kitchen waste, and stable combustion is achieved. can be suppressed to

By placing a catalyst filter in the exhaust port 6 or waste duct 7, smoke, odor, and other toxic gases such as No, x, and Co contained in the exhaust gas can be removed.
etc. can be removed.

When the combustion is completed, the temperature inside the incineration chamber surrounded by the cylindrical cage 3 decreases, so the temperature change after combustion is detected using, for example, an infrared sensor or thermistor, and when the temperature falls below the set value, , the oscillation operation of the magnetron 10 is stopped.

When a certain amount of ash has accumulated in the ash storage container 18,
Pull it out of the housing and dump the dust.

Effects of the Invention The kitchen waste processing device of the present invention divides the inside of the pot-shaped kitchen waste collector into a plurality of sections by partition walls, and a heating element that absorbs microwaves and generates heat is placed in one of the sections. Combustion becomes stable.

Therefore, even if there is a large amount of kitchen waste, it can be safely incinerated, and there is no fear that a large amount of exhaust gas will be generated at once, making it easy to purify it.
