Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art As a method for treating kitchen waste, especially food waste, which is generated every day in kitchens such as general households and restaurants, there is a method utilizing microbial decomposition. This method is useful for reducing the amount of waste, can contribute to the reduction of the processing load at the waste incinerator and the sewage treatment plant, and is attracting attention as being desirable from the viewpoint of environmental protection.

A compost container has been conventionally known as this type of food waste processing apparatus. This is a cylindrical container with a lid plate on the opening on one side, and it is used by embedding it in the soil for a suitable length with the opening on the other side facing downward.The lid plate is opened and raw garbage is put inside. After that, the lid plate is left closed and the input garbage is decomposed by the activity of microorganisms that propagate in the soil to be composted.

However, in the compost container, the presence of the soil for the embedding is a prerequisite for use, and the decomposition of the food waste inside the container slowly occurs, so that a large-capacity container is required to increase the throughput. In addition, there is a possibility that a strange odor generated due to disassembly may leak out to the surroundings, and there is a problem that it is not suitable for use in urban areas where there are many apartments such as condominiums and apartments. However, there is also a problem in handling compost produced by decomposition when it is used in.

The present applicant has already filed an application for a food waste processing apparatus which solves these problems, utilizes decomposition by microorganisms, and can be used in urban areas. The conventional food waste treatment device according to the application of the present applicant has a hollow container (treatment tank) having an appropriate inner volume, and is used for culturing microorganisms such as wood chips such as sawdust, chaff, rice bran, and soil. It is a device having a simple structure in which a processing medium suitable for the above is stored, and a garbage input port is provided in the upper part of the processing tank and a drain port is provided in the bottom part.

The inside of the treatment tank is maintained in an environment (temperature, humidity, etc.) suitable for the propagation of microorganisms, and a mixing means is arranged inside the treatment tank. This mixing means, for example, rotationally drives a stirring wheel embedded in the processing medium about the horizontal axis, and performs an operation of mixing the food waste introduced from the food waste introduction port into the treatment medium substantially evenly. The mixed garbage is mixed with water (H ₂ O) that can be discarded into sewage beyond the composting stage due to the activity of various microorganisms that propagate in the treatment medium kept in a favorable environment. It will be decomposed into carbon dioxide (CO ₂ ) that can be released into the atmosphere, and there will be no trouble in disposing of the product.

Microorganisms that propagate in the treatment medium are roughly classified into worms such as ringworm, nematode and protozoa, and fungi such as cocci and bacilli, and the garbage put in the treatment tank is mainly preferable. The fungi acting in an anaerobic environment act on intermediate products such as sugars, amino acids, and organic acids that are decomposed by the predatory action of the worms that operate in an aerial environment. Then, it is decomposed into water and carbon dioxide which are final products.

[0008]

Even in such a conventional food waste treating apparatus, for example, when the amount of food waste introduced exceeds the amount of microorganisms decomposed, the decomposition rate is delayed and the garbage is naturally decomposed. A state similar to rotting may occur, and an odor may be generated, which causes various inconveniences when it is installed in the cooking chamber. In addition, general garbage that is not decomposed by microorganisms is also generated from the kitchen, but this general waste has the trouble of separately preparing a garbage casing for processing.

The present invention has been made in view of the above circumstances, and by arranging the food waste processing device outside the cooking chamber, the inconvenience caused by the generation of odors is eliminated, and a garbage casing for general garbage is also attached to this. The purpose of the present invention is to provide a garbage disposal device that can easily dispose of general garbage.

[0010]

A kitchen waste disposal apparatus according to the present invention is an outer casing disposed outdoors, and a food waste disposal device for decomposing food waste by the activity of microorganisms contained in the outer housing. And a waste box for storing waste that is not decomposed by microorganisms, a waste disposal port opened on the inner wall surface of the house, and a chute that connects the waste disposal port with the garbage processing device and the waste case, respectively. Is characterized by.

[0011]

In the present invention, this makes it possible to easily separate raw garbage from general garbage, and the raw garbage is decomposed as it is by microorganisms so that the odor and rotten odor of the garbage do not enter indoors. .

To be done. During this period, the operation control unit heats the processing medium 22 by issuing an energization command to the heater H based on the detection result of the internal temperature of the processing medium 22, for example.

As described above, the treatment medium 22 inside the treatment tank 21 is a microbial culture substrate that forms an environment suitable for the growth of microorganisms, and the temperature in the treatment medium 22 depends on the activity of the microorganisms themselves and the heater. By appropriately energizing H, the temperature is maintained at a temperature suitable for the growth of microorganisms. Therefore, in the treatment medium 22 inside the treatment tank 21, various microorganisms brought in together with the garbage are propagated, and the garbage is decomposed by the activity of these microorganisms during the standby state. In addition, the garbage in the processing medium 22 is stirred by the stirring blade after it is put in.
Since it is crushed by the rotation of 25b, the decomposition treatment is performed in a relatively short time.

Microorganisms that propagate in the treatment medium 22 are ringworms,
Consisting of worms such as nematodes and protozoa, and fungi such as cocci and bacilli, the food waste in the treatment medium 22 firstly contains sugars by predation of the worms that act in an aerobic environment. It is decomposed into an intermediate product such as an amino acid and an organic acid, and then decomposed into water and carbon dioxide which are final products by the activity of the fungus in an anaerobic environment.

A part of the produced water is taken into the treatment medium 22 and has a function of maintaining the humidity suitable for the growth of microorganisms, and most of the remaining water flows down in the treatment medium 22 and the drain portion 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 into the upper space of the processing tank 21, and is discharged into the atmosphere through the exhaust port 29.
