Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention aims to reduce weight and volume by directly dumping household garbage discharged from a kitchen or the like into a drain of a sink, and crushing, dewatering and drying outside the room. In addition, wrapping of garbage prevents garbage from being transported and prevents moisture from being reabsorbed, allowing for direct disposal of garbage without touching hands, and greatly reducing the load on municipal waste incinerators. The present invention relates to a garbage reduction processing device.

[0002]

2. Description of the Related Art The processing of garbage generated from daily living is increasing year by year, and municipalities collect and transport garbage.
Incineration requires a great deal of disposal costs, and has become a major social issue that has squeezed the municipal finances. There is a tendency for more municipalities to pay for garbage collection in order to reduce the amount of garbage. For this reason, a method of processing garbage in each home has been devised and put into practical use. A method using anaerobic microorganisms to put garbage into compost to decompose microorganisms and use the treatment liquid as fertilizer, or disposing a disposer below the sink and attaching a blade to a rotating body to crush the garbage finely, The method of flowing directly to the sewer is generally used.

[0003] However, the former composting method,
The garbage must be transported to the compost installed in the yard, and the decomposition of the garbage takes several days and is accompanied by a bad smell, so it is limited to home use with a large garden. In the latter disposer treatment, crushed garbage is directly discharged to the sewer, which causes clogging of the sewer and generation of offensive odor, which is a social problem and restricts the use of the disposer in some municipalities. .

[0004] In recent years, various devices for effectively separating and eliminating household garbage have been developed and used. For example, a microbial destruction treatment apparatus that decomposes garbage generated at home using aerobic microorganisms in several hours to ten and several hours has been developed and marketed. In addition, a garbage processing apparatus has been developed and marketed in which garbage is pulverized to reduce the volume of the garbage, then heated and dried by an electric heater, a microwave, or the like, and water is actively evaporated to reduce the volume.

[0005]

[Problems to be Solved by the Invention] However, in the microbial decomposition treatment method, since it is a separately installed type which is generally installed outdoors and used, it is necessary to transport garbage to an outdoor decomposition treatment device. There is a problem that garbage waste liquid adheres to the human body and clothes and gives discomfort to the processor.

[0006] In addition, in the microbial decomposition treatment method, since living microorganisms are used, it is necessary to control temperature conditions and humidity conditions for the microorganisms to proliferate comfortably. When the house is emptied, the microorganisms may die, and in the biodegradation method, two microbial carriers may be used.
-It is necessary to change every 3 months, and it is impossible to increase the processing amount suddenly, such as when the amount of garbage is increased by visitors, etc. Further, a bad odor is generated, so a deodorizing mechanism is required. In addition, the latter heating and drying type processing apparatus requires a large amount of electric energy for heating and drying, and has problems such as generation of harmful gas due to drying.

[0007] Recently, a processing apparatus of a type in which a garbage microbial decomposition processing apparatus is directly connected to a drain port of a sink has been developed in order to save troublesome transportation of garbage. It takes a great deal of trouble to replace each time, and it is difficult to completely suppress the generation of offensive odor, and there is a danger of ruining the atmosphere of a special meal.
