Abstract

PURPOSE:To incinerate garbage and make the sanitary control in a kitchen easy by installing a heating element heated by absorbing microwaves, an electric heater, and a magnetron applying the microwaves to the garbage and the heating element to be stored in a garbage storing box. CONSTITUTION:After garbage is charged into a garbage storing box 6, a magnetron 19 is oscillated and also an electric current is carried to an electric heater 9 to heat it. 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 in the box 6 is dried up in an extremely short time and a heating element 8 absorbing the microwaves absorbs the microwaves to be heated. The element 8 reaches temp. of about 700-900 deg.C and the garbage inside is ignited and burnt. On the other hand, as the heater 9 is so arranged to surround the garbage, the garbage is heated from its circumference and starts to be burnt from the outside.

Description

[Detailed Description of the Invention] Industrial Application Field The present invention is a kitchen waste processing device, in particular, a kitchen waste processing device that burns food waste (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 for disposing of kitchen waste, a kitchen waste storage pond is generally arranged at the drain port of a water tank in a kitchen sink, and kitchen waste is poured into this storage tube to collect it. Once the kitchen waste is taken out, it is placed in a kitchen waste storage container placed inside or near the kitchen sink, and then taken out and disposed of on the garbage collection day, which is approximately twice a week. However, with this method, you have to replace the rotten and foul-smelling kitchen waste with plastic bags, or put the kitchen waste itself into the storage container with your bare hands.
Furthermore, performing these tasks in a kitchen that should be clean poses 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 sewage that exceeds standard values5, so there are significant restrictions on the use of disposers even in areas with sewage systems. In areas where disposal facilities are not fully equipped, disposers cannot be used due to regulations such as the Waste Disposal Law.

If kitchen waste could be incinerated whenever it is generated, the above-mentioned problems would be substantially 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, kitchen waste can be easily incinerated because water contained in it evaporates and dries in a very short time when exposed to microwaves due to the high dielectric constant of water.

An object of the present invention is to provide a kitchen waste processing device that can incinerate kitchen waste for a short time every time it is generated.

Means for Solving the Problems The kitchen waste processing apparatus of the present invention comprises a kitchen waste storage body, a heating element that absorbs microwaves and generates heat disposed within the kitchen waste storage body, an electric heater, and a kitchen waste storage body. It is equipped with a magnetron for irradiating microwaves to the kitchen waste to be stored and the heating element.

Operation The kitchen waste stored in the kitchen waste storage body is heated and dried by microwave irradiation, and is burned by receiving thermal energy from the microwave absorption heating element and electric heater, which generate heat by microwave irradiation, and becomes ash. Become.

This heat insulator 22 is made of the same material as the heat insulator 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.

First, the lid 20 is opened, kitchen waste is put into the kitchen trash storage body 6, the lid 20 is closed to prevent microwaves from leaking, and then the magnetron 19 is made to oscillate. At the same time, the electric heater 9 is energized to generate heat. The microwave propagates within the waveguide 17, passes through the low dielectric constant heat insulator 5 and the garbage container 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 6 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 absorbing heating element 8 has a columnar shape, the kitchen waste in the kitchen waste storage body 6 surrounds it, and the temperature of objects in or near it receive radiant heat and rise in temperature. Moreover, since the microwave absorbing heating element 8 reaches a temperature of 700 to 900° C., the kitchen waste inside ignites and burns due to the heat. On the other hand, since the electric heater 9 is arranged so as to surround the kitchen waste, the kitchen waste is heated from around by the electric heater 9 and starts burning from the outside. Since kitchen waste is dried by microwave irradiation, it easily ignites and is incinerated in a short time. In order to promote this combustion, air is introduced into the garbage container 6 through the intake holes 10, 12.11, and exhaust gas is passed through the exhaust duct 16 through the exhaust holes 14, 15, 13 to the outside. It is discharged.

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 per normal household cooking, a microwave output of 5GO to 700W will incinerate several tens of minutes or more. will burn out in a short time. Then, by incineration, it becomes odorless and harmless ash with a weight ratio of less than 1/1 oo. In addition, by placing a catalyst filter in the exhaust hole, smoke and odor can be eliminated.

Other toxic residues such as NoX and Co can be removed.

When the combustion is completed, the temperature inside the garbage container 6 decreases, so the temperature change after combustion is detected using an infrared sensor or thermistor, and when the temperature falls below the set value, the magnetron 19 oscillates. The operation is stopped and the power to the electric heater 9 is turned off.

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.
