DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for drying or incinerating garbage.

[0002]

2. Description of the Related Art Garbage generated daily from kitchens, restaurants, various business establishments, and the like is generally transported to incineration plants by municipalities by garbage trucks for incineration. However, the garbage collection work is not performed every day except for the food and beverage industry, and in the summer and in regions with high temperatures, garbage quickly emits a rotten odor, so it is not necessary to wait for collection. There is a high demand for processing. On the other hand, incineration of garbage requires a large amount of fossil fuels, and is a matter that cannot be overlooked in terms of resource depletion and environmental conservation measures.

[0003] In order to respond to such a demand, a plastic container without a bottom and a top lid is placed on the ground, and garbage is put into the container, decomposed by soil bacteria to compost, rice bran or the like. A method in which a variety of bacteria are propagated in appropriate organic powder and mixed with garbage and fermented in a container to form a compost, a method of incinerating garbage in an incinerator, or applying electric hot air to garbage Various methods have been devised, such as a method of cooling and drying water vapor generated from garbage and removing it as condensed water.

Each of these methods has advantages and disadvantages.
For example, the method of treating with bacteria needs to secure a space for installing the container outdoors for a long period of time, and also requires an environment that can effectively use the compost generated thereby. Bacterial fermentation requires a fermentation period of at least 14 days, has the disadvantage of taking too much time, and requires a use environment such as compost. In addition, the incineration method prepares the installation space of the incinerator outdoors,
It was necessary to prepare a heat for incineration, and there were many restrictions on the use of the hot-air drying treatment method, such as an expensive apparatus and a long time required for the drying treatment.

[0005]

A first object of the present invention is to reduce garbage in a short time, at least to such an extent that it does not rot.
An object of the present invention is to provide an inexpensive garbage disposer that can be dried. A second object of the present invention is to disclose a garbage disposer that can dry or incinerate garbage without generating much odor. A third object of the present invention is to disclose a garbage disposer that has a structure that is easy to clean and has high thermal efficiency.

[0006]

The first gist of the present invention is to provide a garbage roaster in a garbage processing chamber made of a heat-resistant material such as steel, stainless steel, cast iron, or ceramic and having an opening on an upper surface. The garbage processing chamber is divided into a garbage loading chamber above the roaster and an air chamber below the roster, and the opening at the top of the garbage processing chamber is closed by a lid that can be opened and closed. At the same time, on the lower surface of the lid, an electric heater for heating garbage is provided in a state facing the rostral, and the electric heater is a power limiting unit, for example,
A garbage disposer characterized in that it is configured to be connected to a power supply via a timer switch and a heat generation amount selection circuit.

[0007] The garbage is placed on a rostor made of a wire mesh, a perforated plate, a metal grid, a ceramic plate having an elongated gap or an opening, and an electric heater such as a sheathed heater is selected by a timer or the like. If the current is supplied for a certain period of time, the state can be changed from a dry state to a carbonized state and further to an incinerated state according to the amount of garbage and the current supply time. Since the garbage processing chamber is almost closed, it does not burn with flames and emits little smoke. Since volatile components generated from garbage due to the heat treatment pass through the high-temperature heater section on the back of the lid,
A significant portion of the odor components are deodorized by thermal decomposition.

In the case of Rostor, the garbage particles having a reduced volume after being dried fall into the air chamber, so that only the surface is scorched in a lump state, and the central portion remains in a soft state without moisture being removed. This does not occur, and the drying proceeds sequentially, so that the thermal efficiency is good and the processing time is short. In order for Rostor to exert such an effect,
Assuming ordinary household garbage, at least 5m
It is preferable that the mesh is provided with a mesh opening having an m square opening or an opening having an area equivalent to the mesh opening. is there. In addition, the electric heater is electrically separated into a plurality of energizing units and mounted so that the amount of heat generated by the electric heater can be selectively adjusted according to the amount of garbage, and each energizing unit is used alone or Alternatively, a plurality of energizing units may be combined to enable energization.

A second gist of the present invention is to provide a raw garbage roster in a garbage processing chamber made of a heat-resistant material and having an opening on an upper surface, so that the garbage processing chamber can be disposed above the garbage. The compartment is separated into a mounting chamber and an air chamber below the roster, and the opening on the upper surface of the garbage disposal chamber is closed by an openable and closable lid, and on the lower surface of the lid,
An electric heater for heating garbage is provided in a state opposite to the rostrum, and a ventilation opening is provided in the upper plate and the lower plate constituting the lid, and the inner space of the lid sandwiched between the upper plate and the lower plate. Has a deodorizing filter, and the electric heater is configured to be connected to a power supply via a timer switch.

[0010] By adopting such a structure, water vapor generated as the garbage placed on the roaster dries,
The odor and other vaporized components are first heated by the electric heater, then enter the inside of the lid through the ventilation opening, pass through the deodorizing filter housed in the lid, and pass through the ventilation opening on the top of the lid to the outside. The odorous component is first subjected to thermal decomposition by a heater, and then contacts a deodorizing filter to be deodorized. As the deodorizing filter, a filter having a catalytic decomposition action such as zeolite, or a filter having an oxidation catalyst dispersed and supported on a heat-resistant carrier (for example, rock wool) is used. The lid bottom plate is
It has the role of reflecting the radiant heat from the electric heater downward, but it is naturally heated by the radiant heat, so that the inside of the lid becomes high temperature, and the catalytic decomposition of odor components is promoted. No condensed water remains in the body.

A third gist of the present invention is to provide a garbage roster in a garbage processing chamber made of a heat-resistant material and having an opening on an upper surface, so that the garbage processing chamber is provided with garbage above the roster. The compartment is divided into a mounting chamber and an air chamber below the rostral, and the opening on the upper surface of the garbage disposal chamber is closed by an openable and closable lid. , In a state of facing the rostral,
Provide an electric heater for garbage heating, the electric heater,
A garbage disposer characterized by being configured to be connected to a power supply via a timer switch.

The invention according to the third aspect differs from the invention according to the first or second aspect only in that an electric heater is also provided in the air chamber. If the garbage is heat-treated from above and below, the processing speed is improved accordingly. The electric heater may be provided only in the lower part of the garbage processing chamber, and may be provided not only in the upper part and the lower part of the processing chamber but also in an intermediate part, a side surface, or an outer periphery.

In the inventions according to the first and second aspects, the roster is provided so as to be rotatable by a slight angle about a pair of fulcrums provided on the peripheral part of the rostral. The operation rod integrally extended from the peripheral portion of the roaster is configured to protrude outside the garbage processing chamber through the side wall of the garbage processing chamber, so that vibration can be applied to the roster from outside. A part or all of the roster is connected to an electric heating element, for example, an electric heating wire such as a nichrome wire through a heat-conductive heat-insulating insulator such as aluminum oxide powder or the like, through a heat-resistant metal pipe (for example, stainless steel). Pipe), or a heater formed by shaping the heating wire into a desired rostral shape with the heating wire embedded in ceramic.
The clogging of the rostrum is extremely small, and the fall of the dried garbage is promoted. Also, since the thermal efficiency is good, the object can be achieved with lower power.

According to a fourth aspect of the present invention, in the above-described garbage disposal apparatus, the bottom of the garbage disposal chamber includes a dish and supporting legs vertically suspended from the bottom of the dish, and The room side wall is configured separately from the bottom of the garbage processing chamber, and by mounting the side wall of the garbage processing chamber on the dish, the garbage processing chamber is configured to have a configuration. Since the lid, the body part forming the side wall of the garbage disposal chamber, and the dish part forming the bottom of the garbage disposal chamber have separate structures, they are convenient for washing, storing, and the like.

[0015]

FIG. 1 shows a first embodiment of a garbage disposer according to the present invention. The garbage disposer 1 includes a stainless steel cylinder 2, a lid 4 for closing the upper opening of the cylinder 2, and a dish 5 detachably fitted to the lower circular opening of the cylinder 2. The garbage processing chamber 6 is surrounded by the plate 5, the lid 4, and the cylinder 2. The processing chamber 6 is provided with a garbage storage chamber 7 above the roster by a rostr 3 provided across the lower half thereof.
And the air chamber 8.

As shown in FIG. 2, the rostre 3 is made of wire welded in a lattice shape, and one wire 3b crossing the center of the circular shape formed by the peripheral portion 3a is separated from the peripheral portion by the wire 3b. The operating rod 3c is extended and penetrates the cylinder 2, and extends obliquely upward. Reference numeral 2a denotes a fulcrum of a rostor formed of a protruding piece protruding from the inner peripheral surface of the barrel at a position facing the penetrating portion 2c of the operation rod 3c.
With the penetrating portion 2c as a fulcrum, the rostr 3 is formed at a predetermined angle by another protruding piece 2b or the like protruding from the inner peripheral surface of the cylinder body 2 so as to have a level slightly lower than these fulcrums.
It can be rocked.

The plate body 5 closes the lower opening of the tube body 2 by being externally fitted to the lower end edge of the tube body 2, and an opening 5b is formed in the rising edge 5a of the plate body. I have. On the other hand, an air introduction hole 2d is also provided in the lower portion of the cylinder body at the same height as the opening 5b. Therefore, the cylinder body is rotated so that the air introduction hole 2d and the opening 5b at the rising edge are formed. , The air chamber 8 communicates with the outside air. Reference numerals 5c,... Denote legs vertically provided from the lower surface of the plate body 5, and the lower ends thereof are connected to the heat reflection plate 9. The heat reflection dish is, for example, a stainless steel plate having a mirror surface.

On the back surface of the lid 4, a heat insulating layer 10 made of a heat-resistant heat insulating material, for example, rock wool, diatomaceous earth or the like is provided.
The electric heater 11 is supported below the heat-insulating layer by a suspension arm 12 suspended from a heat-resistant covering plate 10 a holding the heat-insulating layer 10 on the lower surface of the heat-insulating layer 10. An electric heater is formed by spirally forming a sheathed heater wire in which a heating wire such as a nichrome wire is housed in a stainless steel pipe via a heat conductive insulator (eg, aluminum oxide) having good thermal conductivity. It is. An end of the electric heater 11 penetrates the lid 4 and protrudes from the upper surface thereof to form a connecting portion 11a. The protruding portion is connected to the timer switch 14 and a plug as a connecting device via the heat-resistant cord 13. Are connected to a plug 15 with a timer which is integrated. 2f and 4a are handles, respectively.

[0019]

In the above-mentioned apparatus, the drained garbage is placed on the roaster 3 and covered with the lid 4, and the air introduction hole 2d is provided.
In a closed state, the plug 15 with a timer is plugged into a household power outlet. By operating the timer dial 14, a predetermined time, for example, when the power of the heater is 600
When processing about 800 grams of garbage at watt hours, the time is set in the range of 30 minutes to 1 hour. In about 30 minutes, the garbage dries to such an extent that it does not rot even if left for longer. After one hour, the garbage is completely carbonized. At that time, if the air introduction hole is slightly opened, the ash is completely incinerated. Further, since the cylinder body 2 and the dish body 5 are separated from each other, they can be washed with water as needed. By providing the heat reflecting plate 9 having the projections 9a, 9a,... Protruding downward below the plate 5, the heat radiation from the plate to the floor surface can be achieved without providing a heat insulating material to the plate. The floor can be prevented from overheating.

[0020]

FIG. 3 shows a garbage disposer 20 according to a second embodiment of the present invention. Inner cylinder 22a and outer cylinder 22b made of a metal plate having high heat resistance such as stainless steel
Are combined with a slight gap therebetween to form a double body, and the cylindrical body 22 is formed by a heat insulating panel formed by filling the gap with a heat-resistant heat insulating material 30a. The lid 24 for opening and closing the upper opening of the cylindrical body 22 is substantially the same as the lid 4 of the first embodiment, except that the shape of the electric heater is the same as that of the first embodiment. While the electric heater 31 has a spiral shape, the only difference is that the electric heater 31 is disposed so as to meander on a plane parallel to the lid.

The space inside the cylinder 22 that constitutes the garbage processing chamber 26 is divided by the roster R into a garbage processing chamber 27 above the roster and an air chamber 28 below. The roster R is constituted by a metal mesh plate 25 placed and supported on a circular metal frame 23 along the inner peripheral surface of the cylindrical body 22, and extends from a part of the metal frame 23. Operation stick 2
Reference numeral 3a penetrates the cylinder 22 and projects to the outside. By manipulating this, the roster can be swung back and forth by a slight angle as described later.

That is, the rod R is swingable about a projecting piece 29a projecting from the inner peripheral surface of the cylinder 22 and the cylinder penetrating portion 22c of the operating rod as a fulcrum. A protruding piece that defines the lower limit of one side of the area. The other projection (not shown) is provided on the inner peripheral surface of the cylinder body at a position symmetrical to a straight line connecting the fulcrums. The mesh plate 25 has a bottom surface 25b protruding downward from the metal frame 23, and an upper end peripheral portion 25a forming the maximum diameter of the mesh plate is engaged with the metal frame 23 from above, so that the mesh plate 25 is detachably fitted to the metal frame. I agree.

Reference numeral 25c denotes a handle frame provided on the periphery of the mesh plate. The mesh plate 25 is made of stainless steel and has a square mesh having a side of about 5 mm or more. The mesh size is 5 to 3 depending on the properties of the garbage, particularly the particle size and size.
It is selected from a range of 0 mm. In the case of ordinary households that normally eat rice, the range is preferably 5 to 15 mm, and 8 to 12 mm.
However, the falling condition accompanying the drying of the trash is the best. The shape of the mesh is not limited to the square, but may be a circle, a polygon, or the like.

The cylinder body 22 is placed on a dish 26 composed of a heat insulating panel having a plate-shaped heat insulating material 30c therein, so that the lower end opening of the cylinder body is openably closed. I have. 26a are legs for supporting the plate 26 at a predetermined height. An electric heater 35 is provided on the upper surface of the plate body so as to face the rostrum R.
The electric heater 35 has a configuration in which a sheathed heater wire is bent in a meandering state in a plane.
6 protrudes from the back surface.

An energizing terminal 3 for the electric heater on the upper surface of the lid
A conductive wire coated with heat-resistant insulating material such as glass fiber is connected to 2a and the energizing terminal portion 35a of the dish, and the convex connection devices 36a and 36b provided at each end are connected to a home power supply. Can be selectively connected to the concave connection tools 37a and 37b provided on the plug 37 with a timer having the connection terminals as required. The most effective size of the eyes of the mesh plate 23b constituting the rostrum should be treated,
Although it depends on the type of garbage, as the garbage dries, the size is selected as a guide so that the garbage easily falls from the mesh when the volume is reduced.

However, this does not mean that the size of the mesh is set to a size that cannot be passed when garbage is first placed. Normally, garbage is often entangled with each other to form a nodule, so that even with a mesh several times as large as garbage particles, garbage often hardly falls down. Further, as in the case of the first embodiment, a notch is provided in the rising edge 26b of the plate body, and a notch is similarly provided in the lower edge of the cylinder body 22. It may be an air inlet.

[0027]

The mesh plate 25 of Rostor R is removed, and the well-dried garbage is placed on the mesh plate 25 and set on the metal frame 23.
Cover the lid 24 and connect the connecting devices 36a, b and 37a, b
Are connected to each other, and the energizing time is set by the timer dial 38. The garbage is quickly dried and carbonized by being heated from above and below. Upon further heating, it is incinerated. Usually, if you take it out in a dry state,
Since further decay does not progress, it can be treated like normal waste.

In the garbage disposer of the second embodiment, since the mesh plate of Rostor can be removed, the garbage can be easily set, and even if carbide adheres to the mesh plate, it is easily taken out and cleaned. Can be. In addition, the size and shape of the mesh can be freely selected according to the nature of the garbage to be processed. Garbage is heated from the top and bottom at the same time,
Drying and incineration are prompt. In particular, the garbage that has fallen on the dish is strongly heated, so that little dry garbage remains on the dish. As in the case of the first embodiment, the garbage disposal chamber can be separated into a lid, a cylinder, and a dish, so that cleaning and cleaning can be easily performed.

[0029]

Embodiment 3 FIG. 4 shows a garbage disposer according to Embodiment 1 shown in FIG. 1, in which a rostrum 3 is connected to a sheath heater wire 41 as shown in FIG.
As in the case of 1 or 35, what is bent so as to form a meandering shape in the plane is used as the rostr 40, and both ends of the sheathed heater wire and the vicinity thereof are aligned in parallel, and the connection terminals 41a and 41b are used as the cylinder body. , And an outlet with a timer attached to this terminal via a conducting wire. Of course, the plug with a timer may be used in common with the heater for the lid as in the case of the second embodiment. The roaster 40 may be provided with heat transfer rods 43, 43,... Which intersect with the sheath heater wire to form a mesh. It may be used in combination with a dish. All other configurations,
This is the same as the first embodiment, but in this case, the electric heater provided on the lid side may be omitted.

[0030]

The operation is the same as in the above two embodiments.
Put the garbage on the roster, close the lid, and energize for a predetermined time. Since the garbage disposer according to the third embodiment heats the garbage from below and immediately below the garbage, the calorific value of the electric heater can be small, and the garbage can be dried, reduced in volume, or deformed. Therefore, the garbage that has fallen downward from the rostrum is also quickly dried despite the small amount of heat generated, since the distance between the garbage and the electric heater is short.
Although it is desirable that the rostre itself oscillates,
The same applies to the embodiment, but this is not essential. In the above-described first to third embodiments, the generated steam exits through the gap between the lid and the barrel. Of course, a steam outlet may be formed in the lid, or the steam outlet may be opened near the upper edge of the cylinder body.

[0031]

Fourth Embodiment FIG. 5 shows a garbage disposer according to a fourth embodiment of the present invention. Outer container 52 having opening 53 on top
Through the opening 53, the inner container 5 is inserted into the outer container 52.
5 are housed therein to form a garbage disposal chamber 51.
The garbage processing chamber 51 is supported by a rostor support portion 56 formed of a plurality of projections protruding along the circumferential direction in the vicinity of an intermediate portion of the inner container. The inside of 51 is divided into a garbage loading chamber 58 and an air chamber 59 above Rostor.

An insulating wall 54 made of a heat-resistant insulating material such as rock wool or glass wool is provided on the inner surface of the outer container 52.
Is stretched, and a slight gap 60 is provided between the inner surface of the heat insulating wall 54 and the outer surface of the inner container 55. 54a is a pin for fixing the heat insulating wall 54 to the inner surface of the outer container. A flange 55a is provided on the upper edge of the inner container 55, and the flange 55a is in contact with the folded edge 52a provided on the upper edge of the outer container 52 from above. A lid 62 is placed at the upper opening of the garbage processing chamber 51, and the opening is openably closed.

A substantially disk-shaped lower plate 63 is provided on the lid 62.
A dish-shaped upper surface plate 64 in a state of being laid down on the lower surface plate has a shape integrated at its peripheral edge, and a heat insulating material 66 is provided in a space sandwiched between the upper and lower surface plates. Is stored. When the processing chamber 51 is closed by the lid 62 and the processing chamber 51 is closed, the sheath heater wire is swirled in a plane facing the rostral with a slight gap below the lower surface plate in a state of facing the rostral 57. An electric heater 68 formed so as to have a shape is provided. The surface of the lower plate 63 exposed to the garbage loading chamber preferably has a heat-resistant mirror surface in order to reflect radiant heat. The electric heater 68
Has an end portion which penetrates the lid 62 and protrudes from the upper surface of the lid, to which a connection terminal 70 to a power supply is fixed. The connection terminal 70 includes a timer 72 and a connection terminal 73 to a power source.
And a connection device coated with heat-resistant, which can be detachably connected. 76 is a handle, and 77 is a leg supporting the outer container.

[0034]

The difference between this embodiment and the first to third embodiments is that
Since the garbage processing chamber 51 is surrounded by the heat insulating wall 54 and the heat insulating gap 60, even if the inner container becomes a certain high temperature,
The influence of heat on the outside is small, and therefore, heat loss is small, and uniform heating can be performed. The water vapor dissipates from a gap appropriately provided between the lid 62 and the upper edge of the processing chamber 51 by the press groove 79 or the like. The garbage particles, which have dried to some extent on the roaster and have lost their surface tackiness, fall into the air chamber 59, but since the peripheral wall of the air chamber is also hot, the falling particles quickly dry in the air chamber. Receive.

At the end of the treatment, the volume of the garbage is reduced to about 1/5 when the garbage is in a dry state where the decay does not proceed. Therefore, if the dried garbage remains on the roaster, it can be dropped into an air chamber as appropriate, and then the garbage can be placed on the roaster again for processing. The dried garbage after the treatment can be handled in the same manner as ordinary dried garbage, and of course, can be used as a raw material for compost. The inner container and the roaster can be removed from the outer container and easily cleaned.

[0036]

Embodiment 5 FIG. 6 shows a fifth embodiment of the present invention. The only difference from the fourth embodiment is the configuration of the lid.
The other configuration is completely the same as that of the fourth embodiment. Therefore, members having the same functions are denoted by the same reference numerals as those of the fourth embodiment, and description thereof is omitted. The lid 80 that closes the upper opening of the inner container 55 has a substantially disk shape having a hollow portion surrounded by the upper surface plate 81 and the lower surface plate 82, and a deodorizing filter 85 is housed in the hollow portion. . From the lower plate, a sheathed heater wire protrudes into the garbage storage chamber 58, spirally circulates, forms an electric heater 88 facing the rostral, then enters the lid again, and A connection terminal 86 of a power cord is fixed to a protruding end of the peripheral portion of the power cable 81.

A plurality of ventilation openings 82a, 82
are formed in the upper surface plate, and an opening 83 is formed in the center of the upper surface plate.
To a closing plate 84 provided with a plurality of ventilation openings 84a,.
Are detachably screwed to the periphery of the opening 83. The lower plate 82 and the flange 55a provided on the upper edge of the inner container 55 are formed so as to be in close contact with each other. As the deodorizing filter stored in the lid, a filter in which an oxidation catalyst such as palladium or vanadium oxide is supported on a breathable fabric of heat-resistant fiber such as rock wool or glass fiber, or an appropriate particle size is used. A filter carrying a substance having heat resistance and having a catalytic action on thermal decomposition of odor components, such as zeolite, is preferred.

[0038]

In the garbage disposer according to this embodiment, most of the steam, combustion gas and various volatile gases generated by drying and incineration of the garbage enter the lid through the ventilation openings 82a,. Then, the gas passes through the deodorizing filter 85 and is discharged outside through the ventilation opening 84a of the closing plate 84. Evaporation and vaporization components generated from the garbage first come into contact with a red-heated electric heater and undergo thermal decomposition. Decomposes by contacting the catalytic material
The odor components are decomposed and deodorized or the odor is reduced. Other operations are the same as in the fourth embodiment.

[0039]

[Effect] The garbage disposer of the present invention can treat garbage without requiring a large space as in composting garbage. Odors generated from garbage due to the heat treatment are thermally decomposed and mostly deodorized when passing through a high-temperature electric heater section or a deodorizing filter provided on the back surface of the lid.
In addition, by appropriately setting the heating time and / or the calorific value as required, the processing can be stopped mainly by only discharging the moisture of the garbage, so that there is no waste of energy. In addition, the heating time of the electric heater is set by a timer, and furthermore, the garbage processing chamber is heated almost in an isolated state from the surrounding atmosphere without supplying combustion air, so that no flame is generated, There is no risk of fire due to overheating.
