Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to the improvement of a garbage disposal device that ferments and decomposes garbage generated from the kitchens of homes, restaurants, etc., for example.

[Conventional technology]

When disposing of food waste from home kitchens, etc., a widely used method has traditionally been to dig a hole in a sunny garden, bury the food waste, and ferment and decompose it using the action of microorganisms in the soil. I came here, but
Recent housing conditions have made it difficult to use this natural method, so local governments now have to separate and collect food waste from kitchens, then transport it to incinerators for bulk disposal.

However, with the uneven distribution of the living population and the diversification of eating habits, the generation of food waste has increased significantly in urban areas.
On the other hand, there is a problem that it is difficult to construct new incinerators due to smoke pollution and odor pollution, so it seems that existing facilities have reached their limits in processing food waste.

(a) Therefore, the inventor of the present invention first proposed a food waste disposal device that uses a fermentation accelerator (see Japanese Patent Application No. 61-6733 = Japanese Patent Application Laid-open No. 62-225299) to efficiently process food waste. Fermentation conditions can now be created artificially.

The fermentation accelerator used to create this fermentation condition is a blend of several types of aerobic mesophilic bacteria.
Moreover, it is made by multiplying and concentrating the blended microorganisms while maintaining their balance, and then adding appropriate growth ingredients and deodorizers to the concentrated product. Food waste can be efficiently fermented in a box of this size.

In other words, if a predetermined amount of the fermentation accelerator is sprinkled on top of the food waste placed in the container once a day, the food waste in the container will efficiently ferment over time and turn into water. Therefore, the amount of food waste remaining in the container after 1 to 2 months is 1/10 of the total amount of food waste that was put in.
It is said that it will decrease to a certain extent.

(b) Furthermore, the present inventor has developed a garbage disposal device using this fermentation accelerator that is more suitable for home use. ) proposed the garbage disposal equipment described in . Its structure is to overlap the cut end surfaces of cut cardboard materials so that the inner space follows the outer circumferential wall and fix them in a rectangular tube shape. A rectangular cylinder having a reverse bent part cut orthogonally into the rectangular cylinder, and a groove-shaped cross-section having an opening in a corner part which is inserted from the upper and lower ends of the rectangular cylinder and into which the reverse bent part can be folded and connected. This garbage disposal device has a main body composed of a mold and a formwork, which occupies a significantly smaller space before assembly, making it convenient to transport. The cylindrical body and the formwork body can be inseparably integrated, and the overall cost can be reduced by using lightweight and inexpensive corrugated cardboard material.

[The problem that the idea aims to solve]

However, since the garbage disposal device described in (b) had a single outer peripheral wall, although the cardboard material itself has some degree of insulation, it is difficult to block the cool outside air when installed outdoors such as on a balcony. was insufficient, and the fermentation temperature could not be maintained at an appropriate temperature. In addition, the structure is such that food waste is stored directly in an inner bag that is loaded along the inner circumferential surface of the main body, and new food waste must be sequentially stored on top of the food waste that is in the process of fermentation, so that it cannot be disposed of properly. I couldn't get a cycle. In addition, the structure allows garbage to be stored directly in the inner bag, and the water produced during fermentation is drained by a combination of a drainage hose and a plastic foam slanted to the bottom of the container. In some cases, the waste that remains as solid material that does not turn into water flows into the drainage hose provided at the bottom of the inner bag without being filtered, causing a phenomenon in which the hose becomes clogged and prevents proper drainage.

[Means to solve the problem]

In order to achieve the above object, this invention overlaps the cut end surfaces of cut cardboard materials so that the inner space is along the outer peripheral wall and fixes them in a rectangular tube shape.
A rectangular cylinder having a reverse bent part cut perpendicularly to the ridge line at the upper and lower ends of a part or all of the corner parts; A garbage disposal device comprising a main body constituted by a formwork with a cross-sectional groove shape having an opening in a corner part that can be folded and connected, a concave bottom plate member attached to the main body, and an inner periphery of the main body. a water-resistant inner bag that is loaded along the surface and has a drainage hose that extends outside the main body through the bottom plate member; and a plurality of small containers each having a large number of drainage holes.

[Effect]

The function of this device with this configuration is that by creating a double structure on the outer peripheral wall of the main body and small containers, the cool outside air is blocked and the fermentation temperature inside the main body is maintained at an appropriate temperature. By vertically dividing the inside of the main body, it is possible to determine an appropriate disposal cycle for garbage, and to ensure good drainage conditions without clogging the drain hose.

〔Example〕

Next, this invention will be explained based on an embodiment shown in the accompanying drawings.

Fig. 1 is a partially cutaway external perspective view showing the garbage disposal device of the present application, Fig. 2 is an exploded perspective view, Fig. 3 is a perspective view showing the bottom plate, Fig. 4 is a perspective view showing the lid, and Fig. 5 is an exploded perspective view. It is a perspective view of a small container.

In the figure, reference numeral 100 indicates the garbage processing apparatus of the present invention, which includes a rectangular cylindrical main body 1 made of cardboard and a bottom plate member 1.
0, a lid member 20, and a small container 30.

That is, after covering the main body 1 with the bottom plate member 10 attached thereto with a water-resistant inner bag 40 made of vinyl or the like along its inner circumferential surface, the small container 30 is inserted so as to partition the inside of the main body 1 vertically. Furthermore, after inserting the net bag 50 for storing food waste into the small container 30, the lid member 20
The garbage processing apparatus 100 is constructed by covering the material with the material.

Thus, the main body 1 is fixed by overlapping the cut end surfaces of the cut corrugated cardboard so that the inner space thereof is along the outer peripheral wall 2a, and the ridge line is attached to the upper and lower ends of some or all of the corners. A rectangular tube body 2 is formed with a reverse folded part 4 cut in an orthogonal shape, and the rectangular tube body 2 is fitted from the upper and lower ends to reinforce the upper and lower openings of the rectangular tube body 2. It is composed of a formwork body 3 having a groove-shaped cross-section and having openings 5 and 6 at the corners, through which the part 4 can be folded and connected. In that case, the creation method is as follows.

(a) Cut plastic cardboard to the required length in the longitudinal direction. In this case, the required dimension refers to the sum of the total length of the four outer peripheral walls 2a of the rectangular tube body 2 and the overlapping allowance of the two cut ends.

(b) Form four crease lines in the cut cardboard material, bend it into a square tube, and overlap the two cut ends at approximately the center of one of the outer peripheral walls 2a to make the square tube body 2. . Note that when the outside of the overlapping portion of the cut ends is sealed using a suitable windproof seal 7, the cut end surface of the corrugated cardboard material is sealed as described later, and the internal void (94 in FIGS. 8 and 9) is sealed. ，
95) from the outside air.

(c) A total of eight reverse bent portions 4 are cut into each corner of the upper and lower ends of the rectangular cylinder 2 perpendicularly to the respective ridge lines.
form. Note that the reverse folding portion 4 may be formed in advance in the step (a).

(d) Make two formwork bodies 3 having the structure shown in Figure 2. In this case, each form body 3 has a groove-shaped peripheral wall 3a.
and 3b are formed, and apertures 5 and 6 are formed in the circumferential walls 3a and 3b located at each corner, and the openings 5 and 6 are shaped so that the reversely folded portion 4 of the rectangular cylinder 2 can be folded and coupled.

(e) Fit this form body 3 into the upper and lower ends of the rectangular cylinder body 2, and fold the reverse bent portions 4 of the rectangular cylinder body 2 into the openings 5 and 6 of the form body 3, and the formwork body 3 are combined into an integral state as shown in FIG. As a result, the frame body 3 sufficiently reinforces the upper and lower openings of the rectangular cylinder body 2.

Now, this main body 1 and the bottom plate member 10 attached thereto are constructed so as to be fitted together on the inside or outside of the lower form body 3, but the combination method can be determined by an appropriate method. . The inner surface of the bottom plate member 10 is formed into a concave surface that gradually descends from each side toward the hose outlet 11 in the center.

The concave surface of the bottom plate member 10 and the inner surface of the outer peripheral wall 2a of each cylinder 2 form the inner surface of the main body 1.

Reference numeral 20 denotes a lid member for covering the upper opening of the main body 1, which is configured to be removably attached to the inside or outside of the form body 3 fitted into the upper side of the rectangular cylinder body 2, and has a lid member in the central portion thereof. An appropriate handle 21 is formed.

Reference numeral 30 denotes a triangular small container that is inserted and removably inserted into the upper opening of the rectangular cylinder 2 or the main body 1 and partitions the main body 1 vertically. The shape is such that they can be arranged symmetrically with some distance between them.

Further, as shown in FIG. 5, this triangular small container 30 is constructed as a combination structure of a triangular peripheral wall 31 and a triangular bottom plate 32, and the peripheral wall 31 is the outer peripheral wall of the rectangular cylinder 2. 2a to form a double wall structure, and a number of drainage holes 33 are formed in the lower region of the peripheral wall 31 and the bottom plate 32. In this case, the material of the small container 30 may be any water-resistant and rigid material, but for example, a plastic cardboard material may be used so that the voids created by the core are continuous in the vertical direction, and the voids are filled with the drainage holes 33. More preferably, it can be used as a drainage ditch that communicates with the drain. Moreover, the diameter of the drainage hole 33 is preferably about 5 to 8 mm.

Note that the number of installed triangular small containers 30 is 2.
The size of the main body 1,
It can be determined depending on the input amount of garbage, insertion cycle, etc.

40 is a water-resistant inner bag made of, for example, a thin vinyl sheet, which is attached to the square tube 2 so as to cover the inner surface of the outer circumferential wall 2a of the square tube 2 forming the inner surface of the main body 1 and the concave surface of the bottom plate member 10. It is formed as a rectangular bag with a similar rectangular opening, and as shown in FIG. 6, a drainage hose 41 of a predetermined length is attached to the center of the bottom surface.

The height and main body length of the inner bag 40 are set to such a length that the opening edge portion 42 of the inner bag 40 can be folded back to the outside of the square tube body 2, that is, longer than the height of the square tube body 2. ing. Note that the bottom surface of the inner bag 40 is preferably formed into a convex surface that fits in with the concave surface of the bottom plate member 10.

This inner bag 40 protects the paper cardboard material from moisture generated by fermentation of garbage when the main body 1 is made of paper cardboard material, and protects the inner surface of the main body 1 when it is made of plastic cardboard material. This is effective for avoiding contamination at least in the upper region of the surface.

As shown in FIG. 8, the corrugated cardboard material 90 constituting the main body 1 usually has a flat plate-like structure on its front and back sides, sandwiching a member (core) 91 formed in a corrugated shape (other shapes are also available). members 92 and 93 are provided, and these flat members 92 and 93 and the central core 91
The structure is such that internal voids 94 and 95 that are continuous in one direction are formed between the two.

When manufacturing plastic products, they are made by extrusion, but when this extrusion method is used, there is almost no restriction on the dimension L in the longitudinal direction of the product (the direction in which the internal void extends). However, the width dimension W is limited to a certain extent due to the molding die.

On the other hand, since the garbage disposal device of the present invention is intended for household use, when trying to mold the main body 1 into a size suitable for installation in a limited space such as a balcony, the rectangular cylinder body 2 The total length of the four peripheral walls may be longer than the width W of the corrugated cardboard material set in a normal molding die. In this case, the total length of the four circumferential walls of the rectangular tube 2 is taken in the longitudinal direction of the corrugated cardboard material, cut, and then bent into a square tube to form the four circumferential walls and form the rectangular tube 2. Become.

At this time, as shown in FIG. 9, the cut ends 96 and 97 of the corrugated cardboard material are overlapped and fixed, so that the internal spaces 94 and 95 are exposed from the cut end surfaces.

Therefore, when the wind A hits the main body 1 placed outdoors, a part of the wind A blows into the internal spaces 94 and 95.
As a result, it enters the inside and goes around the outer circumferential wall of the main body 1 using these spaces 94 and 95 as a passage, passing through the main body 1 in a state as if air cooling it, and depriving the temperature necessary for fermentation within the main body 1. (This is the opposite of the original purpose of using cardboard). Therefore, it is effective to seal the cut end surfaces of the corrugated cardboard materials overlapped on the outer circumferential wall of the rectangular tube body 2 with the wind-shielding seal 7 to prevent this air cooling phenomenon.

Next, how to assemble and use the garbage processing apparatus 100 configured as described above will be explained.

First, as shown in FIG. 7A, the lower formwork 3 is fit-fitted onto the lower end of the rectangular cylinder 2 with the wind-blocking seal 7 applied to the cut end surface. The lower reverse folding portion 4 of the rectangular tube body 2 is reversely folded into the openings 5 and 6 of the frame body 3, and the rectangular tube body 2 and the lower frame body 3 are joined together.

Next, as shown in FIG. 7B, the bottom plate member 10 is fitted to the lower form body 3 combined with the rectangular tube body 2 to form the main body 1, and the main body 1 in this state
An inner bag 40 made of vinyl or the like is attached to the inner surface of the bag.

In this case, first, the tip of the drain hose 41 of the inner bag 40 is taken out from the hose outlet 11 of the bottom plate member 10 to the outside of the bottom plate member 10, and then the opening edge 42 of the vinyl inner bag 40 is widened and the rectangular tube body 2 Fold it back to the outside of the opening.

In addition, the inner bag 40 is assembled in a different order so that it is expanded inside and outside the main body 1 after the main body 1 is formed, that is, after the upper and lower formwork bodies 3 are connected to the upper and lower ends of the rectangular tube body 2. You can.

Next, as shown in FIG. 7C, a pair of triangular small containers 30 are inserted facing each other into the main body 1 with the inner bag 40 attached, so that the inside of the main body 1 is vertically divided. Divide into. It is convenient to insert a mesh bag 50 for directly storing garbage into the small container 30 so that you do not have to get your hands dirty when taking it out.

Finally, as shown in FIG. 7D, the inner bag 40 is attached to the upper end of the rectangular cylinder 2 of the main body 1 in which the inner bag 40 is attached and the pair of triangular small containers 30 are inserted.
Insert the upper form body 3 from above 0, and fold the upper reverse folded part 4 of the rectangular cylinder body 2 into the openings 5 and 6 of this upper form body 3 to integrate both 2 and 3. Combine,
A garbage processing device 100 is formed.

Now, when using this food waste disposal device 100, first, once a day, a predetermined amount (preferably 5 or less) of food waste is placed in one triangular small container 30.
A predetermined amount of fermentation accelerator is sprinkled on top of the fermentation promoter, and then the lid member 20 is placed on the lid.

Repeat this every day, and when one small container 30 is full, put garbage into the other small container 30, and when the other small container 30 is full, remove the first small container 30 from the main body 1. Take it out, put the garbage inside into a disposal bag, and have it collected by a garbage truck.

In this case, the food waste put into one of the small containers 30 is fermented over time by a fermentation accelerator and becomes water droplets, and the waste that remains as solids is filtered through the drainage hole 33 of the small container 30. Only the wastewater that remains in the small container 33 and passes through the drain hole 33 flows out into the inner bag 40, passes through the drain hose 41 that penetrates the bottom plate member 10, and is discharged to the outside of the garbage processing apparatus 100.

As a result, the amount of food waste thrown into the small container 30 until it is full is reduced by approximately 1/2% (over a period of 1 to 2 months) until the food waste thrown into the other small container 30 becomes full.
3, and the moisture content of the remaining garbage is also significantly reduced.

In this case, there is no bad odor from the drained fermentation water or the remaining raw garbage, so there is no need to worry about the odor, and when handling the garbage when dumping it or replacing the small container 30, It won't stain your hands or clothes.

Note that the net bag 50 may be a bag made of polyethylene film with small holes formed therein, or a bag made of woven or knitted fabric. The mesh of this net bag 50 is smaller than the drainage hole 33 provided in the small container 30, and is preferably about 2 to 5 mm.

As explained above, in the food waste disposal device 100 according to this invention, the amount of food waste put into the main body is reduced by its fermentation action, and the main body and the plurality of parts vertically partitioned By having a double-wall structure with a small container, the inside of the main body is insulated from the cool outside air, making it possible to maintain a good fermentation temperature. In addition, since food waste can be divided and stored in small containers, an appropriate disposal cycle can be determined, and there is no risk of waste remaining as solids flowing into the drain hose, resulting in good fermentation efficiency. As a result, the amount of garbage collected by garbage trucks will be significantly reduced compared to the past, making it possible to significantly reduce the burden of garbage disposal on local governments.

Moreover, in this garbage processing apparatus, since the garbage after fermentation is discarded, it is possible to prevent the generation of a bad odor that is associated with ordinary garbage and the staining of hands and clothes during disposal.

Furthermore, if the cut ends of the corrugated cardboard stacked on the outer peripheral wall of the rectangular cylinder are sealed with a wind-blocking seal, the air cooling phenomenon that occurs when outside air passes through the internal voids of the corrugated cardboard can be effectively prevented. I can do it.

Although one embodiment has been described above, it should be noted that the present invention is not limited thereto, and can be modified in various ways without changing the gist thereof.

For example, the cross-sectional shape of the outer container is not limited to a rectangular shape, but can also be other square shapes. In this case, the cross-sectional shape of the small container-equivalent member inserted inside should also be changed accordingly. There is a need.

[Effect of idea]

As mentioned above, when this invention is used, it is possible to create a new container that prevents damage from the cool outside air, even though it is made of corrugated cardboard, and also improves the ability to drain water as fermentation progresses. It becomes possible to realize a garbage disposal device.
