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.

BACKGROUND ART Traditionally, kitchen waste has been disposed of by - Generally speaking, a kitchen waste storage basket is installed at the drain of the water tank of the kitchen sink, and the kitchen waste is poured into the storage basket and collected. The kitchen waste is first removed and placed in a kitchen waste storage container located near the kitchen sink, and then taken out and disposed of on garbage collection days, which occur approximately twice a week. but,
This method requires replacing rotten and foul-smelling kitchen waste with plastic bags, or putting the kitchen waste itself into storage containers with bare hands, and these tasks must be done in a kitchen that should be 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, when kitchen waste occurs, it can be disposed of immediately.

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

The present invention is intended to solve the above-mentioned problems, and aims to provide a kitchen waste processing device that can make kitchen waste odorless and harmless by incinerating kitchen waste using microwaves and turning it into ashes.

Means for Solving the Problems The kitchen waste processing apparatus of the present invention includes a kitchen waste incineration device that incinerates kitchen waste by irradiating it with microwaves, and air is supplied from the microwave generator side through a waveguide to the kitchen waste incineration device. It is designed to be supplied within the

Operation With the above configuration, the kitchen waste is irradiated with microwaves in the kitchen waste incineration device to generate heat, and the moisture contained therein begins to evaporate. At this time, air heated by the microwave generator is sent in to speed up the evaporation of the moisture and the resulting drying and combustion of the kitchen waste.

Embodiments Below, embodiments of the kitchen waste processing apparatus of the present invention will be described with reference to the drawings.

[Example 1] As shown in FIG. 1, the kitchen waste processing apparatus 1 of this example includes a cylindrical kitchen waste collector 3 having a plurality of through holes 2, and a kitchen waste collector 3 having a cylindrical shape, for example, a cylindrical kitchen waste collector 3. It is equipped with a kitchen waste incineration device 4 connected to the lower part of the container 3, and is installed, for example, in a kitchen sink, and the kitchen waste collector 3 is connected to a drain port 6 of a water tank 5. A first microwave shield 7 is attached between the kitchen waste collector 3 and the kitchen waste incineration device 4 so as to be openable and closable. The kitchen waste incineration device 4 has a kitchen waste combustion chamber 8 at the top.
, the lower part is disposed of in the ash collection chamber 9, and a second microwave shield 10 is attached between these double portions so as to be openable and closable. These microwave shields 7 and 10 are made of metal that has excellent heat resistance and does not oxidize even when heated. 8 to the kitchen waste collector 3 side, and is configured to prevent moisture contained in the kitchen waste in the upper kitchen waste collector 3 from easily entering into the kitchen waste combustion chamber 8. The microwave shielding plate 10 prevents microwaves from leaking from the garbage combustion chamber 8 into the ash collection chamber 91′ilt! when it is closed.
Further, the structure is such that water does not enter the dust collection chamber 9 from the kitchen waste combustion chamber 8. Inside the kitchen waste combustion chamber 8, a cylindrical microwave heating cylinder 11 is disposed below the kitchen waste collector 3 so as to be substantially coaxial therewith. The microwave heating cylinder 11 is made of a porous sintered body of a dielectric material such as silicon carbide or ferrite, and absorbs microwaves to self-heat to several hundred degrees.

The kitchen waste collector 3 is arranged in a water tank-like room, and a drainage vibrator 12 is connected to the lower part of the side wall. and,
This drainage vibrator 12 is branched in the middle and is also open-connected to the lower side wall of the garbage combustion chamber 8. Even if water flows into the kitchen waste collector 3 together with kitchen waste, most of it is discharged to the sewer through the drainage vibrator 12. When cooking is busy and a large amount of kitchen waste is generated, the kitchen waste may fall into the kitchen waste combustion chamber 8 without being sufficiently drained by the kitchen waste collector 3. At this time, since the microwave heating cylinder 11 is a porous body, much of the water contained in the kitchen waste is absorbed by it, and the unabsorbed water is transferred to the kitchen waste combustion chamber 8.
It is discharged from the lower part of the body through the drainage vibrator 12.

One end of a waveguide 14 is connected to the intake port 13 of the kitchen waste combustion chamber 8, and a magnetron device 15 is attached near the other end of the waveguide 14. Further, the other end of the waveguide 14 is open, and a metal net 16 for preventing microwave leakage is attached.

This opening portion and one end of the heat dissipation portion of the magnetron device 15 are connected by an air guide body 17 as shown in FIG. An air blower 18 is disposed on the other end side of the heat dissipation portion of the magnetron device 15. When the magnetron device 15 oscillates, the blower 18 blows kitchen waste from the heat dissipation portion of the magnetron device 15 through the air guide body 17 and the waveguide 14. Air is sent into the combustion chamber 8. At this time, the air flow removes heat from the heat radiating portion of the magnetron device 15 and flows into the kitchen waste combustion chamber 8 as a hot wind.

On the other hand, one exhaust pipe is connected to the exhaust port 18 of the kitchen waste combustion chamber 8, and when the kitchen waste is incinerated, exhaust gas is discharged from the kitchen waste combustion chamber 8 through this exhaust pipe 19 by the air blown by the blower 18.

In the apparatus configured as described above, first, kitchen waste generated by cooking etc. flows into the kitchen waste collector 3 from the drain port 6 of the water tank 5 together with water. At this time, the microwave shields 7 and 10 are closed. The moisture content in the kitchen waste flows out from the through hole 2 of the kitchen waste collector 3 and is discharged through the drain pipe 12.The kitchen waste is collected in the kitchen waste collector 3, and is placed in a microorganism at a predetermined stage or as needed. When the wave shield 7 is opened, the microwave heating cylinder 1 installed in the kitchen garbage combustion chamber 8 below is exposed.
Fall into 1.

After dropping the kitchen waste into the microwave heating cylinder 11, etc., the microwave shield 7 is closed and the blower 18 is operated, and the kitchen waste is passed through the heat dissipation part of the magnetron unit 1115, the air guide body 17, and the waveguide 14 into the kitchen waste combustion chamber. Blow air to 8. At the same time, the magnetron device 15 is caused to oscillate, and the waveguide 1
When microwaves are sent into the kitchen waste combustion chamber 8 through the microwave heating cylinder 11 and the kitchen waste, the microwave heating cylinder 11 and the kitchen waste each absorb the microwaves and generate heat, reaching a temperature of several hundred degrees or more.

At this time, the airflow passes through the heat radiation part of the magnetron device 15 and becomes hot air and flows into the kitchen waste combustion chamber S, so that drying and combustion of the kitchen waste is promoted. Exhaust gas is exhausted from the exhaust pipe 19.

In this way, there are two methods: one method in which the kitchen waste directly absorbs microwaves to cause self-heating, one method in which the microwave heating cylinder 11 absorbs microwaves to indirectly heat the kitchen waste, and a method in which the magnetron device 15 is further cooled. Kitchen waste can be easily combusted by supplying and heating the hot air obtained by heating.

When the incineration is completed, the oscillation operation of the magnetron device 15 is terminated, the air is blown by the blower 18 for a certain period of time, and then the air blowing is stopped, and the microwave shield 10 is opened (the kitchen garbage combustion chamber 8
The ash inside is disposed of into the ash collection chamber 9 provided at the bottom.

This ash collection chamber 9 is equipped with, for example, a drawer 20 that can be pulled out in the direction of the page (thereby, the ash can be easily taken out and disposed of).

It would be very convenient if the series of operations described above were automatically performed, for example, by a microcomputer-controlled drive device (not shown).

In addition, if the wall of the kitchen waste combustion chamber 8 is made of metal, and metal utensils such as spoons and forks are mixed in with the kitchen waste, there will be a gap between these metal utensils and the wall of the kitchen waste combustion chamber 8 during microwave irradiation. However, in the device of this embodiment, the kitchen waste is dropped into the microwave heating cylinder 11, and then the microwave is heated. Since it is configured to burn by irradiating waves, even if there are metal utensils mixed in the kitchen waste, the microwave heating cylinder 11 is interposed between them and the wall of the kitchen waste combustion chamber 8. There is little risk of electrical discharge occurring.

[Example 2] This example is a partial modification of the apparatus of Example 1, but the difference is that the bottom part 21 of the microwave heating cylinder 11 is a kitchen waste combustion chamber with a microwave shield of 1°. 8 side, and is configured to be inserted into and removed from the microwave heating cylinder 11 according to its opening and closing. Note that the bottom portion 21 is made of the same material as the microwave heating cylinder 11.

The functionality of this embodiment is substantially the same as that of embodiment 1.

According to the apparatus of this embodiment, when kitchen waste is incinerated, the bottom part 21 is inserted into the microwave heating cylinder 11, and it becomes a bottomed cylinder, so that the wall part of the kitchen waste combustion chamber 8 and the microwave shielding The occurrence of discharge between the device and the body 10 can be more effectively prevented than in the device of the first embodiment.

As described above, according to these embodiments, kitchen waste generated in the kitchen can be easily incinerated, reduced in volume, and made harmless by using microwaves.

The opening cross-sectional shape of the microwave heating cylinder 11 is the same as or larger than the cross-sectional shape in the direction perpendicular to the axis of the garbage collector 5, and furthermore, the part of the dust receptacle of the drawer 17 has a shape similar to that of the microwave heating cylinder. By making the cross-sectional shape of the opening the same as or larger than 11, kitchen waste and dust are reliably transferred downward.

Effects of the Invention According to the kitchen waste processing apparatus of the present invention, kitchen waste generated in the kitchen can be easily incinerated, reduced in volume, and disposed of. During the incineration, the heat obtained by cooling the microwave generator7
In order to send lice, combustion is efficient (not only can it be done, but also
The microwave generator can be protected from harmful gases generated from the materials to be combusted.
