DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to refuse which can decompose kitchen waste generated in a kitchen by microorganisms (hereinafter referred to as garbage).
And a garbage disposal apparatus capable of being separated into refuse that is not decomposed by microorganisms or easily decomposed (hereinafter referred to as general refuse).

[0002]

2. Description of the Related Art As a method for treating kitchen waste, particularly kitchen garbage, which is generated daily in kitchens such as ordinary households and restaurants, there is a method utilizing decomposition by microorganisms. This method is useful for reducing the amount of garbage, can contribute to the reduction of the processing load in garbage incineration plants and sewage treatment plants, and is attracting attention as being desirable from the viewpoint of environmental conservation.

[0003] As this type of garbage processing apparatus, a compost container has been conventionally known. This is a cylindrical container with a lid plate on one side opening, which is used by embedding it in the soil for a suitable length with the other side opening downward, opening the lid plate and putting garbage inside. After that, the garbage is put into a compost state by leaving the lid plate closed and decomposing the input garbage by the activity of microorganisms that propagate in the soil.

[0004] However, compost containers require the presence of soil for embedding as a prerequisite for use, and the decomposition of garbage in the interior occurs slowly, and a large-volume container is required to increase the throughput. Above all, there is a risk that an unpleasant odor generated due to the decomposition may leak to the surroundings, which is not suitable for use in an urban area where there are many condominiums such as condominiums and apartments. However, there is also a problem that it is difficult to handle the compost generated by the decomposition.

[0005] The present applicant has already filed an application for a garbage disposal apparatus which solves these problems, utilizes decomposition by microorganisms, and can be used in an urban area. A conventional garbage disposal apparatus according to the present applicant's application is a method for culturing microorganisms such as woody debris such as sawdust, rice husk, rice bran and soil in a hollow container (treatment tank) having an appropriate internal volume. This is a device having a simple structure in which a processing medium suitable for the above-mentioned process is accommodated, a garbage input port is provided at the top of the processing tank, and a drain port is provided at the bottom.

[0006] The inside of the treatment tank is maintained in an environment (temperature, humidity, etc.) suitable for propagation of microorganisms, and a mixing means is provided inside the treatment tank. This mixing means, for example, rotationally drives the stirring wheel embedded in the processing medium around the horizontal axis, performs an operation of mixing the garbage introduced from the garbage input port into the processing medium substantially uniformly, The garbage mixed in this way goes beyond the composting stage due to the activities of various microorganisms that propagate in the processing medium maintained in good environment, and becomes water (H ₂ O) that can be disposed of in sewage. And it is decomposed into carbon dioxide (CO ₂ ) which can be released to the atmosphere, so that there is no trouble in disposing of the product.

[0007] Microorganisms that propagate in the treatment medium are roughly classified into insects such as wheelworms, nematodes and protozoa, and fungi such as cocci and bacilli. Decomposed by the insects that are active in an aerobic environment, and the fungi that mainly operate in an anaerobic environment act on intermediate products such as saccharides, amino acids, and organic acids generated by the decomposition. Then, it is decomposed into water and carbon dioxide as final products.

[0008]

However, even in such a conventional garbage disposal apparatus, if the amount of garbage input exceeds the amount of microorganisms decomposed, for example, the decomposition rate is delayed and the natural garbage disposal becomes slow. A state similar to putrefaction occurs, and odor may be generated, and when installed in a cooking chamber, various inconveniences are caused. In addition, general garbage that is not decomposed by microorganisms is generated from the kitchen, but this general garbage has to be separately prepared and disposed of.

The present invention has been made in view of such circumstances, and by disposing the garbage disposal apparatus outside the cooking chamber, the inconvenience associated with the generation of odor is eliminated, and the garbage casing for general garbage is also provided. Another object of the present invention is to provide a garbage disposal apparatus capable of easily handling general waste.

[0010]

According to the present invention, there is provided a kitchen garbage disposal apparatus, wherein the garbage disposal apparatus is disposed outdoors and a garbage disposal apparatus for decomposing garbage by the activity of microorganisms contained in the outer casing. And a garbage housing for storing garbage that is not decomposed by microorganisms, a garbage disposal port opened on the inner wall surface of the house, and a chute connecting the garbage disposal port with the garbage disposal device and the garbage housing, respectively. It is characterized by.

[0011]

According to the present invention, the garbage can be easily separated from general garbage by this, and the garbage is directly decomposed by microorganisms, so that the odor and decay odor of the garbage do not enter the room. .

Further, a motor box 27 is provided on the upper inside of the processing tank 21, and a drive motor M is housed inside the motor box 27. The output shaft of the drive motor M and the stirring shaft 25a penetrate one side wall of the processing tank 1 and protrude to the outside of the same, and are connected by a drive chain 25c wound therebetween. The stirrer 25 is rotated by the forward and reverse rotation of the drive motor M, and operates as a mixing unit that stirs the processing medium 22 in the processing tank 21 and mixes it with the garbage to be input.

As shown in FIGS. 2 and 4, the stirring blade 25a is
It has a shape that is curved toward one side in the circumferential direction, has a chevron-shaped cross section with the inside of a curved circle pointed, and rotation of the stirring blade 25b by transmission from the drive motor M is indicated by an arrow in FIG. As shown by, the inner side of the curved circle, that is, the ridge line side of each stirring blade 25b is mainly generated in the previous direction. With this configuration, the agitation of the processing medium 22 by the rotation of the agitating blade 25b is efficiently performed, and the agitation can be performed with a small resistance, so that the power burden on the drive motor M can be reduced.

Inside the processing tank 1, a heater tube 28 containing a heater H is suspended substantially horizontally below the rotation range of the stirring wheel 25. The heater H is controlled by the operation control unit. And heat is generated in accordance with the instruction, and the surrounding processing medium 22 is heated. The periphery of the drainage section 26 is surrounded by a partition plate formed of a perforated metal plate such as a punching metal, and transmits water generated in the processing medium 22 in the process of processing garbage and contains moisture.

Next, the operation of such a kitchen waste treatment apparatus will be described. The garbage generated in the kitchen is stored in a bag made of a biodegradable material, the lid 4a is opened, and the garbage is put into the shooter 6 from the garbage input port 4. When the lid 4a is opened, the micro switch SW is turned on, the drive motor is rotated, and the stirring wheel 25 is rotationally driven. The input garbage is the stirring blades 25b of the stirring wheel 25.
As a result, the bag is broken, and both the food waste and the bag are mixed with the processing medium 22.

After the above-described operation for putting in the garbage, the waiting state is maintained until the next garbage is put in, and the garbage mixed in the processing medium 22 is decomposed during this waiting state. Is done. During this time, the operation control unit issues an energization command to the heater H based on the detection result of the internal temperature of the processing medium 22, for example, and heats the processing medium 22.

As described above, the processing medium 22 in the processing tank 21 is a microorganism culturing substrate that forms an environment suitable for the propagation of microorganisms, and the temperature in the processing medium 22 depends on the activity of the microorganism itself and the heater. By appropriately energizing H, the temperature is maintained at a temperature suitable for the propagation of microorganisms. Therefore, in the processing medium 22 inside the processing tank 21, various microorganisms brought along with the garbage propagate, and the garbage is decomposed by the activity of these microorganisms during the standby state. The garbage in the processing medium 22 is agitated by the stirring blades
Since the particles are crushed by the rotation of 25b, the decomposition process is performed in a relatively short time.

Microorganisms that propagate in the processing medium 22 include rotifers,
Nematodes, worms such as protozoa, and fungi such as cocci and bacilli, and the garbage in the treatment medium 22 is first converted into sugars by predation of the worms that are active in an aerobic environment. It is decomposed into intermediate products such as amino acids and organic acids, and then decomposed into water and carbon dioxide as final products by the activity of the fungus in an anaerobic environment.

A part of the generated water is taken into the treatment medium 22 and acts to keep the humidity suitable for the propagation of microorganisms, and most of the remaining water flows down through the treatment medium 22 to drain the drainage part 26. After that, it is discharged into sewage. On the other hand, the generated carbon dioxide gas is
It rises in the processing medium 22, flows out into the upper space of the processing tank 21, and is discharged to the atmosphere via the exhaust port 29.

On the other hand, general garbage that is not decomposed by microorganisms is housed in a garbage bag made of polyethylene or the like, and the lid 5a is opened in the same manner and thrown in from the general garbage inlet 5. The thrown garbage bag is dropped and stored in the garbage bag 34 in the garbage case 3 via the shooter 7. When the trash in the refuse case 3 is discarded, the door 1a is opened, and the handle 32 is pulled out toward the front by holding the handle 32 in the hand, and the refuse case 3 moves on the rail 1b and is drawn out from the outer case 1. The garbage case 3 may be pushed to the garbage dump and the garbage may be discarded.
