DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention has a simple structure and can be easily used for garbage generated in homes, stores, offices, business establishments and the like having relatively low moisture content of papers and plastics. The present invention mainly relates to a refuse treatment apparatus suitable for household use.

[0002]

2. Description of the Related Art It has been a long time since the reduction of garbage has been called for, but for that purpose it is necessary to grasp the contents of the garbage. For example, the breakdown of garbage discharged from households shows that, excluding cans, bottles, newspapers and other recyclables, garbage generated from around the kitchen, plastics for packaging foodstuffs, and other miscellaneous paper It can be roughly classified into three types of garbage. Among them, the garbage occupies a small volume, and it is said that plastic and paper garbage occupy more than 90% of the total volume. In general, these treatments are performed by a collection vehicle going to a predetermined time and place, collecting them, and intensively performed in a treatment facility such as an incineration plant or a landfill. Therefore, in general households, it is necessary to keep the garbage until a predetermined date when the collection is performed, and it is necessary to transport the garbage to a predetermined place when the collection is performed. In order to eliminate such inconveniences, some apparatuses and methods for processing garbage at (near) a place where the garbage is generated have been proposed. For example, the disposer is of a type in which garbage is finely divided by mechanical force and flows into sewage together with water, and as other methods, a heating combustion method using a heater or the like,
There are a refrigeration method for preventing odor, a microwave heat combustion method, and the like. However, these are all garbage processing apparatuses and cannot be used for reducing the amount of plastics and papers.

[0003]

[0005] Plastic refuse and paper refuse occupy a small amount in the whole garbage but are large in volume. This is because food trays, containers, bottles, packaging bags, wrap films, etc. are discharged as plastic waste, and packaging paper, advertising paper, OA equipment paper, etc., generate a large amount of paper waste, especially at home. It is the main cause of space increase. Furthermore, plastic garbage usually contains vinyl chloride and vinylidene chloride containing chlorine as a chemical component. These plastic garbage, which avoids generation of chlorine-based gas during combustion, should be incombustible (do not burn). They are often treated as garbage) and sent to landfills, causing an increase in the amount of garbage at the final landfill site. In addition, paper waste is usually burned, but it is bulky and requires a large space for storage.

[0004] On the other hand, regarding the conventional refuse treatment apparatus, most disposers, incineration type, refrigeration type, etc. are garbage disposal units, and there is no effective means for plastics and papers. However, practical waste disposal devices for them are still in a state of general use at a level equivalent to that of the prior art, and early realization has been an issue.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, and mainly has a simple structure and can be used easily for garbage generated in homes, offices, business establishments and the like having a relatively low moisture content of papers and plastics. It is an object of the present invention to provide a processing device suitable for home use.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a refuse container having a variable inner volume for storing refuse and a refuse container forcibly changing the inner volume of the refuse container. The refuse treatment apparatus has a configuration including a compression mechanism that uses air pressure to reduce the volume.

[0007]

According to the present invention, waste having a relatively low water content such as plastic waste and paper waste can be removed by the above-described structure and mechanism.
An object of the present invention is to provide an apparatus having a simple configuration and performing processing easily. That is, plastic waste, paper waste, etc. are first put into the waste container. Next, the waste container having a variable internal volume is forcibly operated using air pressure to reduce the internal volume and compress the waste. Garbage stored with the change in the internal volume of the garbage container is easily compressed, and the volume is greatly reduced. This compression step may be repeated a plurality of times. As described above, the amount of waste and the volume can be reduced with a very simple configuration and operation.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Specific examples will be described below in detail. FIG. 1 is a vertical sectional view showing a main part of a first embodiment of a waste treatment apparatus according to the present invention. Reference numeral 1 denotes a garbage container, which has a multi-node shape and is configured to be able to expand and contract by sliding a node portion. As a result, the internal volume is variable. Put garbage such as plastic and paper into this. Here, the refuse container 1 is made of a plastic material, but an FRP material, a metal material, or the like can also be used. Reference numeral 2 denotes a main body container, and reference numeral 3 denotes a door that opens and closes when taking in and out garbage. Both of them and the refuse container 1 are structured to have mechanical strength enough to withstand the force applied to the portion. In addition, the lid 3 has a mechanism (not shown) that can be closed against a force from the inside formed by the main body container 2. Reference numeral 4 denotes a bag provided on the outside of the multi-node garbage container 1, which is made of a flexible plastic material, but may be made of a rubber-based material. Reference numeral 11 denotes a pedestal on which the waste container 1 is placed, and reference numeral 12 denotes a packing for keeping the inside airtight. Reference numeral 8 denotes an air pump, 9 denotes a suction port, and 10 denotes a projection port. The airtight space 13 formed by the main body container 2, the bag 4 and the packing 12, and the air pump 8 constitute a compression mechanism using air pressure. 5 is an exhaust pipe, 6 is an exhaust inlet, and 7 is an exhaust outlet.

Next, the operation will be described. Garbage such as plastic or paper is put into the garbage container 1 and the lid 3 is closed. Next, the air pump 8 is operated. Air is sucked in from the inlet 9 and is introduced into the hermetic space 13 from the outlet 10. Then, the bag 4 is compressed from the outside and pressed against the refuse container 1, and further pushes up the refuse container 1. The node of the refuse container 1 is slid by the force to reduce itself. At this time, the refuse put in the refuse container 1 is compressed and its volume is reduced. When the refuse container 1 is reduced, the air inside the refuse container 1 is discharged from the exhaust port 7 to the outside through the exhaust pipe 5. In this way, waste reduction is very easily achieved. When the set pressure at the time of pressurization is reduced, a high-pressure fan can be used instead of the air pump. Here, since the set pressure at the time of pressurization is 0.2 kg / cm ² and the cross-sectional area of the refuse container in the lateral direction is about 300 cm ² , a high compressive force of about 60 kg in total can be exerted. The set pressure can be further increased, and when an air pump is used, a compression force of about 20 times the above-mentioned pressure can be easily generated, and if an air compressor is used, the pressure can be further increased. Therefore, an appropriate compression force can be selected in a wide range according to the purpose and the like.However, the above-mentioned compression force is sufficient for very common garbage. The above-described setting is advantageous from the viewpoint that an inexpensive configuration is not required because a withstand voltage configuration is unnecessary.

FIG. 2 is a vertical sectional view showing a main part of a second embodiment of the waste treatment apparatus according to the present invention. Reference numeral 21 denotes a garbage container, which has a bellows-like configuration and is capable of expanding and contracting, and has a variable internal volume. Put garbage such as plastic and paper into this. Here, the refuse container 1 is made of a plastic material, but a rubber material, a metal material, or the like can also be used. Reference numeral 22 denotes a main body container, and reference numeral 23 denotes a door that opens and closes when dust is taken in and out. These are structures having sufficient mechanical strength for the purpose, and the lid 23 has a mechanism (not shown) that can be closed against a force from inside formed with the main body container 22. Same as 1. 24
Is a bottom plate of the bellows-like waste container 21 and needs to have rigidity. 31 is a pedestal on which the refuse container 11 is placed, and 32 is a packing for keeping the inside airtight. 28 is an air pump, 29 is a suction port, and 30 is a projection port. Reference numeral 34 denotes a compression bellows, which is formed on the gantry 33 using a plastic material, but may be formed of a rubber-based or metal-based material. A compression space 35 is formed in the compression bellows 34, and forms a compression mechanism using air pressure with the air pump 28. 25 is an exhaust pipe, 2
6 is an exhaust inlet, and 27 is an exhaust outlet. In this embodiment, by operating the air pump 28 to introduce air into the compression space 35 and expand the compression bellows 34, the bellows-like waste container 21 is reduced, and the waste put therein is compressed and reduced.

FIG. 3 is a vertical sectional view of a main part showing a third embodiment of the waste treatment apparatus according to the present invention. Reference numeral 42 denotes a main body container, which also serves as a guide cylinder in this case. An inner plate 44 that is movable along the inner surface while sliding along the inner surface is provided, and a garbage container is constituted by the two, and garbage such as plastic and paper is put into the garbage container. Reference numeral 51 denotes a lower stopper of the inner plate 44, which defines the lowermost position of the inner plate 44. Reference numeral 43 denotes a lid, to which an airtight packing 52 is attached in order to keep the airtightness of a space 53 formed by the main container 42. These are structures having sufficient mechanical strength for the purpose, and the lid 43 has a mechanism (not shown) that can be closed against force from the inside formed by the main body container 42. Same as 1 and 2. 48 is an air pump, 49 is a suction port, and 50 is a projection port. The main body 42, the lid 43, the airtight packing 52, the inner plate 44, and the air pump 48 constitute a compression mechanism using air pressure. 45 is an exhaust pipe, 46 is an exhaust inlet, 4
7 is an exhaust outlet. In the present embodiment, the air pump 48 is operated to introduce air into the lower portion of the inner plate 44 in the space 53, and the inner plate 44 is moved along the inner surface of the guide cylinder, thereby compressing and reducing the waste put in the waste container. Become At this time, by setting the height of the surface of the inner plate 44 in contact with the guide cylinder appropriately, smooth sliding becomes possible. For this purpose, the dish is formed in a dish shape having an appropriate depth. However, if this point is taken into consideration, a disc shape or an inverted dish shape may be used.

In order to extend the waste container, the air pump is stopped and the air used for pressurization is exhausted by utilizing the weight of the waste, or the air is forcibly exhausted using the air pump. Do. Further, the combination of the waste container and the compression mechanism is not limited to that of each embodiment. For example, the combination of the waste container of FIG. 1 or FIG. 3 and the compression bellows 3 of FIG.
