DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a garbage disposal apparatus for treating garbage with microorganisms.

[0002]

2. Description of the Related Art Recently, garbage disposal apparatuses that can easily process garbage in ordinary households are becoming widespread due to the problem of the garbage disposal capacity of each local government. As the garbage disposal apparatus, there are a garbage disposal apparatus capable of reusing garbage as fertilizer, and a garbage disposal apparatus capable of eliminating most of the garbage by microorganisms. Among these, as for the garbage processing apparatus using microorganisms, microorganisms can be easily obtained in recent years due to the development of biotechnology, and various apparatuses are sold by home electric appliance manufacturers and the like.

[0003] A processing apparatus for processing garbage using microorganisms is capable of eliminating most of the garbage put into the garbage,
It has the advantage that odors and insects are hardly generated, and it is a factor that can be easily introduced without much labor. It is particularly useful for condominiums and other condominiums, and recently there are condominiums and detached houses equipped with such a processing device as standard equipment.

[0004]

However, in the conventional garbage disposal apparatus using microorganisms, even if little odor is generated, the garbage does not smell immediately after the garbage is introduced or until the garbage is processed. It was the actual situation. Such a processing device is often installed in a kitchen for convenience, and even a slight odor may cause anxiety. Therefore, it must be installed outside the room, and the convenience is greatly impaired, and it is often not used at all at the end. In particular, in an apartment or the like, there are many restrictions on the installation location outside the room, and in some cases, it may not be possible to install the garbage disposal apparatus at all.

Further, in the garbage disposal method using microorganisms, the decomposition medium and the garbage are periodically stirred to enhance the treatment capacity, so that the decomposition medium and the garbage are mixed and oxygen is supplied. At present, the structure of the conventional stirring apparatus is too complicated and the apparatus itself has to be expensive. A conventional general stirrer has a structure in which a rotating shaft is provided inside a processing tank and stirring blades are attached to the rotating shaft to stir the processing tank. In order to hold the stirring apparatus inside, the processing tank is formed by plastic molding. It has to be integrally molded due to the above, and is expensive. There are various problems such as sealing between the processing tank and the rotating shaft, assembling of the stirrer in the processing tank, strength of the processing tank for rotatingly supporting the stirrer, and the cost is high. There was a disadvantage.
In addition, since the stirring device is provided inside the processing tank, there has been a problem that maintenance such as cleaning of the inside becomes difficult.

[0006]

In view of the above-mentioned problems, the present inventor has made the present invention as a result of intensive studies, which is characterized by the fact that garbage is produced by a decomposition medium containing microorganisms. In the processing apparatus, at least a bottom portion of the processing tank for storing the decomposition medium material and the garbage is formed of an outer member, a flexible material having air permeability and at least a part of which is moved inward by a mixing device. And a suction device for sucking air between the inner member and the outer member is connected to the outer member. It is in.

[0007] Here, the term "decomposition medium material" as used herein.
The term “carrier” refers to a carrier that holds soil microorganisms that degrade proteins, cellulose, and the like. Carriers include, for example, wood chips, wood flour, peat moss, charcoal and charcoal. The garbage is decomposed by mixing and stirring the decomposition medium material and the garbage. The garbage is decomposed into carbon dioxide gas and water vapor by microorganisms, and most of the garbage disappears.

[0008] The "treatment tank" contains a decomposition medium material,
By putting garbage into this part and mixing it,
It refers to a container or a bag for decomposing the garbage. In the present invention, at least the bottom portion of the processing tank has a double structure including an inner member and an outer member. Among them, at least the inner member is formed at least in part of a material having air permeability or a material provided with air permeability, and is provided with a soft portion formed of a soft material. In this case, the outer member may be entirely formed of a steel plate such as plastic or stainless steel, or may be formed of a soft material for the entire or bottom portion.

As such a treatment tank, for example, a double structure in which an inner tank having air permeability and having a soft portion at least at a bottom portion and an outer tank having a soft portion at least at a bottom portion is combined, This is a case where a conventional processing tank is loaded with an inner bag having air permeability and having a soft portion at least in a bottom portion. In addition, an exterior part formed of a non-permeable member such as plastic or stainless steel is provided in the processing apparatus main body, and the exterior side of a processing tank having air permeability and having a soft part at least in a bottom part is partially covered with the exterior part. It may be a covering structure.

In this way, when disposing of the old disintegration medium material, the entire set bag may be discarded, so that a new disintegration medium material can be easily set.

The term "soft material" refers to a member having flexibility and sufficient resilience to repeated deformation when formed into a bag. Examples of such a soft material include a fabric such as rubber and canvas, a sheet such as polyvinyl chloride and polyethylene, a nonwoven fabric, a net, and a composite material thereof. In other words, the soft material does not require any particular waterproofness or water retention, but may be any material that can store and hold the decomposition medium material and the garbage and can sufficiently withstand repeated deformation. By molding or sewing the flexible member into a container shape or a bag shape, all or the bottom of the processing tank and the inner bag are formed.

The "flexible portion" refers to a portion of the inner member such as the processing tank or inner bag formed of all or a part of the flexible material. In the present invention, the inner member of the double structural part needs to have air permeability. That is, by sucking the air between the double structure portions, the air passes through the decomposition medium material through the inner member having air permeability to supply oxygen. The portion for providing air permeability to the inner member is not particularly limited, and may be provided partially or entirely on the inner member. However, it is preferable to provide the softening portion, which is a portion for containing and mixing the decomposition medium material. The flexible portion having air permeability may be formed of a material having air permeability, such as the above-described cloth such as canvas, or may be a non-permeable plastic sheet or the like which is partially provided with air holes to allow air to flow. . In the case where a soft portion is provided on the outer member of the double structure portion, the material is not particularly limited, but is preferably formed of a soft material having almost no air permeability in order to increase air permeability from the inner member.

Further, a heat insulating material may be provided between the double structural parts. The heat insulating material is used to insulate the contents such as the decomposition medium material charged into the processing tank and the inner tank. In the present invention, the double structural portion may be integrally deformed by the mixing device, and in such a case, it is necessary to use a heat insulating material that can cope with the repeated deformation. When only the soft portion of the inner member is moved inward by the mixing device, use a shape-preserving heat insulating material or separate the net or a gas-permeable member so that the heat insulating material is not biased. Need to be retained. In any case, it is necessary to use a heat-insulating material of at least air-permeable material or to provide air-permeable material. As the heat insulating material, any member may be used as long as the air layer is made resident by maintaining the interval between the double structure portions, for example, glass wool, sponge, non-woven fabric, a plurality of protrusions, a net, a three-dimensional mesh. Things. In addition, a plurality of protrusions or ribs may be integrally formed on the outer surface of the inner member or the inner surface of the outer member.

The term "mixing device" refers to a device for moving at least a part of the flexible portion of the inner member inward. In other words, any material may be used as long as the stored decomposition medium material and garbage are mixed by pushing or pulling at least the soft portion of the inner member inward, for example, as in a segmental movement of the stomach. As the mixing device, for example, a pressing tool that moves up and down is disposed below the processing tank and the inner tank, and the contents are mixed by pushing up and down the soft part of the processing tank and the inner tank with the pressing tool. . The mixing device may be arranged on the side of the processing tank or inner tank and pressed from the side, or a string, a wire,
A structure in which a chain or the like is provided and these are lifted may be used. Further, the mixing device may be provided at only one place, or may be provided at a plurality of places and operated simultaneously or alternately. In addition, the contents may be mixed by moving the processing tank up and down. In this case, it is preferable to provide a projection below the processing tank.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on an embodiment shown in the drawings.

FIG. 1 shows an example of an embodiment of a garbage disposal apparatus 1 according to the present invention. The processing layer 2 for storing a decomposition medium 8 containing microorganisms and garbage 9 has a double structure. It was done. Then, a set bag 26 containing the decomposition medium material 8 is set in the processing tank 2, and the garbage 9 is put into the set bag 26. The processing tank 2 is a combination of an inner bag 4 and an outer bag 5 formed of a soft material, and a heat insulating material 6 is interposed between them. The inner bag 4 is formed of a breathable canvas, and the outer bag 5 is formed of rubber. A block-shaped sponge is used as the heat insulating material 6 and is packed between the inner bag 4 and the outer bag 5. In addition, the outer bag 5 is provided with an air inlet 7, and the duct 20 of the air suction device I is communicated with the air inlet 7 to suck air between the inner bag 4 and the outer bag 5, so that the air permeable inner Oxygen is supplied by passing air from the upper opening to the decomposition medium material 8 through the bag 4. in this case,
In this example, an air filter 27 and a deodorizing filter 28 are provided in the air intake device I, so that dust is scattered and deodorized.

The decomposition medium 8 and the garbage 9 stored in the processing layer 2 (set bag 26) are mixed by a mixing device 10 provided below the processing layer 2. The mixing apparatus 10 is of a pantograph type, in which two operating parts are rotatably connected to a gear 29 in which two are meshed, and the gear 29 is rotated by a motor 15 to move the pressing tool 11 up and down. . In this example, a communication portion 18 is provided in the pressing tool 11 to make the air inlet 7 and the duct 20 communicate with each other. This pressing tool 11
As shown in FIG. 2, the bottoms of the flexible portions 3 of the inner bag 4 and the outer bag 5 are pushed up to mix the decomposition medium 8 and the garbage 9. Mixing by the mixing device 10 is 3 minutes to 10 minutes.
Sufficient mixing can be performed only by moving up and down once per minute.

As shown in FIG. 3, the mixing device 10 includes a pressing tool 11 disposed at the bottom of the flexible portion 3 of the treatment layer 2 and a foot pedal 12 for pushing up the pressing tool 11. A structure in which the bottom of the flexible portion 3 is pushed up by the pressing tool 11 by stepping on the pedal 12 may be adopted.

In this case, if the two bags 19 are alternately pushed up by the pressing tool 11, the stored material of one bag 19 moves to the other bag 19 as shown in the figure, and this is alternately repeated. Reliable mixing can be performed. In order to substantially achieve such an object, a structure in which a partition is provided inside the flexible portion 3 may be employed. Also, the processing device 1
May be provided with a plurality of processing tanks 2 and mixed by the mixing device 10.

The processing tank 2 may be entirely formed of a soft material such as cloth or rubber. However, as shown in FIG. 8, the upper cylindrical portion of the processing tank 2 is formed of a plastic molded product, and the lower part thereof is formed of a soft material. A structure for connecting the flexible portions 3 formed of a material may be employed. By doing so, it is only necessary to replace only the soft portion 3 at the bottom, which is relatively easy to wear out, and since it can be kept in a container shape, handling becomes easy. In this example, an opening 21 and a shutter 22 for closing the opening 21 are provided in the cylindrical portion, and a chute 2 is provided around the opening 21.
3 is provided so that the contents can be easily discharged.

Since the garbage processing apparatus 1 according to the present invention has a structure in which air is sucked from the processing tank 2 by the suction device I, odors are not directly scattered from the input garbage 9 and almost no odor is emitted. Therefore, it can be installed indoors without any problem. Therefore, in the case of exclusive use for indoor installation, although there is almost no need to provide a heater for the purpose of enhancing the activity of microorganisms and maintaining the activity, the treatment tank 2 is not required.
It is also possible to provide a heater in the flexible part. Also,
The heater may be provided in a portion of the pressing tool 11 that contacts the outer bag 5 or the inner bag 4.

In the use state of the garbage processing apparatus 1 according to the present invention, the processing tank 2 can be easily removed from the processing apparatus 1 because the processing tank 2 is provided separately from the mixing apparatus 10. In this case, if the suction port 7 and the communicating portion 18 of the pressing tool 11 can be connected when the processing tank 2 is placed on the pressing tool 11 as in the above-described example, the processing tank 2 can be attached and detached. Almost no hassle. Further, even if the duct 20 is connected to the air inlet 7, the duct 20 may be long, or may be detachable with one touch as shown in FIG. In addition, even when the set bag 26 is not used, the contents can be easily discarded. In addition, if the inner bag 4 can be removed from the outer bag 5, regardless of the outer bag 5 to which the duct 20 is connected, only the inner bag 4 is removed from the processing apparatus main body as shown in FIG. It can be disposed of.

In each of the above-described examples, each of the outer member and the inner member of the processing tank 2 is formed of a soft member. However, only the inner member may be formed of a soft member. In this case, as shown in FIG. 11, an inner bag 4 made of canvas is loaded into an outer tank 24 molded of plastic. The heat insulating material 6 is provided on the inner surface of the outer tub 24, and the pressing tool 11 is disposed at the center of the bottom.
Need only be mounted inside the outer tub 24.

Further, as shown in FIG. 12, the exterior part 25 for covering only the bottom part of the inner bag 4 may be provided on the main body of the processing apparatus. This makes it possible to easily provide an opening or the like in the upper cylindrical portion of the structure of the inner bag 4 as described above. The flexible portion 3 is attached to the outer tub 24 and the exterior portion 25.
In the case of a structure in which the inner bag 4 having the above is loaded, the mixing method using the mixing device 10 can be performed in the same manner as in each of the above-described examples. Further, if the outer tub 24 and the exterior part 25 are molded into the shape as shown in FIG. 7 described above, the state conforms to the shape even when the bag-shaped or container-shaped inner bag 4 is loaded. It is also possible to mix by the method described above.

[0029]

As described above, the garbage disposal apparatus according to the present invention has at least the bottom portion of the processing tank for storing the decomposition medium and the garbage having a double structure of an inner member and an outer member. The inner member of the double-structured portion has a structure in which a bottom portion has a flexible portion that has air permeability and is moved inward by the mixing device, and sucks air between the inner member and the outer member. By adopting a structure in which suction is performed by the device, microorganisms can be activated by forcible supply of oxygen, and processing of garbage can be promoted. In addition, since the structure is configured such that air is sucked into the inside of the processing tank from the outside, the dust generated when the decomposition medium material is dried can be prevented from scattering, and the odor generated from the garbage can be sucked without being directly emitted. be able to. These components are absorbed by an air filter, a deodorizing filter, or the like, and the decomposition medium material itself or the inner member itself functions as a filter.

Since the processing tank is not provided with a mixing device, the processing tank itself can have a simple structure, and a decomposition medium material can be stored in a separate set bag, or the processing tank itself can be used. It is easy to remove from the processing device, and the processing and cleaning of the contents becomes extremely simple. In addition, the structure of the mixing device itself for mixing the contents by moving the flexible portion inward can be simplified, and the processing device can be reduced in size and manufactured at low cost. This has a very beneficial effect that excellent waste treatment means utilizing microorganisms can be widely spread.
