Abstract

PURPOSE:To incinerate garbage in a short time and make the sanitary control in a kitchen easy by installing a heating element heated by absorbing microwaves in a garbage storing box and also using a magnetron along with flames produced by a combustion device for the incineration of the garbage. CONSTITUTION:After garbage 23 is thrown in a garbage storing box 6, a magnetron 19 is oscillated. Simultaneously, a combustion device is operated and from its nozzle 9 fire flames are emitted into the box 6. Microwaves are transferred in a wave guide 17 and penetrate through an insulating material 5 with a low dielectric constant and through the box 6 and then supplied to a cylindrical body 2 made of a metal cavity. The garbage 23 is dried up in an extremely short time and a heating element 8 absorbing the microwaves is heated by absorbing the microwaves. The garbage is so arranged as to surround the element 8 and its temp. is raised up by receiving radiation heat. The temp. of the element 8 reaches 700-900 deg.C and the garbage inside is ignited and burnt. On the other hand, the garbage is also burnt by the flames 24 emitted from the nozzle 9 of the combustion device.

Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to a kitchen waste processing device, in particular, a kitchen waste processing device that burns kitchen waste such as kitchen waste generated in the kitchen of a home or commercial cooking facility by irradiating it with microwaves. , relates to a kitchen waste processing device that stabilizes the waste into harmless ash.

Conventional technology Conventionally, as a method of disposing of kitchen waste, a kitchen waste storage basket is generally placed at the drain port of the water tank of the kitchen sink, and the kitchen waste is poured into this storage section to collect it, and furthermore, the kitchen waste is collected once from the kitchen waste storage basket. Remove kitchen waste and place it in a kitchen waste storage container located inside or near the kitchen sink.
The garbage is taken out and disposed of on about 12 garbage collection days. However, with this method, it is necessary to replace the rotten and foul-smelling kitchen waste with plastic bags, or put the kitchen waste itself into storage containers with bare hands, and these operations must be carried out in the kitchen, which should be kept clean. This can be said to be a major problem in terms of hygiene management.

A disposer is a device that can easily solve these problems. According to this, whenever kitchen waste occurs,
It can be processed immediately.

However, in Japan, the Sewerage Law prohibits the discharge of wastewater that exceeds the standard value. Therefore, even in areas where sewage systems are widespread, there are significant restrictions on the use of disposers. In areas where sewage treatment facilities are not fully equipped, disposers cannot be used due to regulations such as the Waste Management Law.

If kitchen waste could be incinerated whenever it is generated, the above-mentioned problems would be solved. However, kitchen waste contains a large amount of water and is difficult to incinerate.

Therefore, it has been proposed to incinerate kitchen waste by irradiating it with microwaves. In this method, since water has a high dielectric constant, kitchen waste can be easily incinerated because the water contained therein evaporates and dries in a very short time when irradiated with microwaves.

An object of the present invention is to provide a kitchen waste disposal device that can incinerate kitchen waste in a short time whenever it is generated.

Means for Solving the Problems The kitchen waste processing apparatus of the present invention includes a kitchen waste storage body, a heating element disposed within the kitchen waste storage body that generates heat by absorbing microwaves, and a flame radiating flame into the kitchen waste storage body. The combustion device includes a combustion device having a nozzle for heating, and a magnetron for irradiating microwaves to the kitchen waste to be stored in the kitchen waste storage body and the microwave heating element.

The kitchen waste stored in the kitchen waste storage body is dried in a short time by microwave irradiation, receives thermal energy from a heating element that absorbs microwaves and generates heat, and is heated by the flame emitted from the nozzle of the combustion device. Burns and becomes ash.

The inside thereof is filled with a heat insulator 21. 22 is an annular heat insulating body, which is used to store kitchen waste when incinerating kitchen waste.
It is arranged between the opening edge portion of the garbage storage body 6 and the lid body 20 in order to prevent heat conduction from there to the lid body 20. This heat insulating body 22 is made of the same material as the heat insulating body 5, and is made of the same material as the heat insulating body 5.

In the apparatus of this embodiment, the cylindrical body 2. Insulator 5. The kitchen waste storage body 6 and the lid 20 constitute a combustion chamber for kitchen waste.

Next, the operation of this embodiment will be described using FIG. 2.

First, the lid 20 is opened, the kitchen waste 23 is put into the kitchen waste storage body 6, and the lid 20 is closed to prevent microwaves from leaking, and then the magnetron 19 is completely destroyed. At the same time, the combustion device is operated to radiate flame 24 from its nozzle 9 into the garbage storage body 6.

The microwave propagates within the conductive tube 17, passes through the low dielectric constant heat insulating body 5 and the garbage storage body 6, and is supplied into the cylindrical body 2 as a metal cavity. Since water has a high dielectric constant, the water contained in the kitchen waste in the kitchen waste container G evaporates first and dries in a very short time. Then, the microwave absorbing heating element 8 absorbs the microwave and generates heat. Since the microwave absorption heating element 8 has a columnar shape, the kitchen waste storage body 6
The kitchen waste inside surrounds it, and things in or near it receive radiant heat and rise in temperature. Moreover, the temperature of the microwave absorption heating element 8 is 700 to 900°C.
This heat causes the kitchen waste inside to ignite and burn. On the other hand, it is also combusted by the flame 24 emitted from the nozzle 9 of the combustion device. Since kitchen waste is dried by microwave irradiation, it easily ignites and is incinerated in a short time. In order to promote this combustion, the air is
0.12.11 into the garbage storage body 6, and exhaust gas is discharged to the outside through the exhaust duct 16 from the exhaust hole 14.1.5.13.

The time it takes to incinerate kitchen waste varies depending on its material, quantity, moisture content, etc., but if it is the amount of kitchen waste in a normal household, a microwave output of 500 to 700W will incinerate several tens of minutes or even longer. It burns out in a short time. When incinerated, it becomes odorless and harmless ash with a weight ratio of less than 1/100. Incidentally, by disposing a catalyst filter in the exhaust hole, smoke, odor, and other toxic gases such as NoX and C○ can be removed.

When the combustion is completed, the temperature inside the garbage container 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 19 is activated. The oscillation operation of the combustion equipment is stopped, and the operation of the combustion device is also stopped.

Then, when necessary depending on the amount of ash, the lid 20
Open it, take out the kitchen waste container 6, and throw away the ashes.

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

Effects of the Invention The kitchen waste processing apparatus of the present invention has a heating element that absorbs microwaves and generates heat disposed inside the kitchen waste storage, and is equipped with a magnetron for supplying microwaves into the kitchen waste storage. Equipped with a nozzle of a combustion device that emits flames to kitchen waste, whenever kitchen waste is generated, it can be incinerated in a very short time in the kitchen and reduced to dust ash, improving hygiene management in the kitchen. becomes extremely easy. Furthermore, since the magnetron and the flame from the combustion device are used together to incinerate the kitchen waste, the incineration time is shorter than when incineration is performed using either the magnetron or the combustion device.
