Even if, therefore, the base materials 27 are packaged in the single bag for easier handling by the consumers, the degradation in their performance does not arise. The base materials 27, consisting of the chaff, etc., are soft decomposable materials contg. lignin, cellulose, hemicellulose, etc., and each one particle thereof is porous, thereby forming large gaps among the respective grains. Excellent moisture adjustment and air permeability are, therefore, resulted even with a small amt. of the base materials 27.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposer for decomposing garbage generated in, for example, an ordinary household kitchen by utilizing aerobic bacteria to reduce the amount of garbage.

[0002]

2. Description of the Related Art A technique for decomposing kitchen garbage (hereinafter referred to as "garbage") using aerobic bacteria in a substrate made of sawdust, rice husk, etc. to reduce the weight is disclosed, for example, in Japanese Patent Application Laid-Open No. Hei 4-4084. Is disclosed.

In this garbage disposal machine, a substrate (microorganism implantation material) and an aerobic bacterium are put into a treatment tank having a stirring blade and a ventilator, and crushed through a crusher to put garbage. Then, the substrate and the garbage are agitated.

[0004]

SUMMARY OF THE INVENTION A processing tank for processing the input garbage, an agitation means for supplying oxygen into the processing tank and crushing the garbage, and discharging the gas from the processing tank to the outside of the tank. Sawdust, a substrate such as rice husk, and an aerobic bacterium are put into a garbage processing tank having a ventilation means to be driven and a driving means to drive the stirring means, and garbage such as cooking waste and leftover food is put. Conventionally, the following problems have been encountered in a kitchen garbage disposer in which garbage is decomposed and reduced by the action of aerobic bacteria by agitation.

[0005] (1) The substrate made of sawdust, rice husk, etc. and the aerobic bacterium have been put into separate bags and packaged because of the decay factor.

(2) A garbage is decomposed in a large amount of base material, and a water-absorbing polymer is used to uniformly and quickly spread water for activating bacteria at the initial start to the surface of the base material. Was packed in a separate bag, so many accessories to put in were very difficult for consumers to handle.

[0007] (3) The conventional base material composed of sawdust, husk, etc. must be processed in a large amount of base material without decomposing garbage.
Breathability and moisture control functions may not work well.

(4) Since the sheet cord heater is attached only to the bottom of the treatment tank, the heat efficiency is poor and the activity of bacteria tends to decrease.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional drawbacks, and mix a base material made of sawdust, rice husk and the like with an aerobic bacterium for decomposing garbage into one bag. Being able to be packaged and shipped makes it very easy for consumers to handle. In addition, since the base material is made non-perishable, such as by reducing the moisture content to 20% or less by hot air drying, a stable base material and a fungicide can be obtained. Even if the garbage is decomposed, the air permeability and moisture control function work well, and a garbage disposal machine with excellent treatment performance can be realized.

[0010] Further, since the planar cord heater is provided on the side surface of the processing tank, the distance from the heater section is short even in the upper portion of the substrate in the processing tank, so that the substrate can be efficiently kept warm. .

[0011]

According to the present invention, there is provided a treatment tank for treating inputted garbage, and oxygen is supplied into the treatment tank.
Put a substrate such as sawdust, rice husk and aerobic bacteria in a garbage processing tank having a stirring means and a ventilation device for crushing the garbage, and a driving means for driving the stirring means, and cooking waste and eating. By mixing and stirring the garbage such as the residue, the garbage disposal machine that decomposes and reduces the amount of garbage by the action of aerobic bacteria decomposes the garbage and the substrate made of sawdust, husk, etc. This is achieved by mixing the aerobic fungicides for packaging into one bag.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing the overall configuration of a garbage disposer for explaining the principle of the present invention, and FIG. 2 is a diagram showing bacteria in a processing tank made of polypropylene resin (hereinafter referred to as PP resin) shown in FIG. 3 is a cross-sectional rear view of FIG. 1 and FIG. 4 is a side view of FIG. FIG. 5 is a cross-sectional view showing the configuration of the planar cord heater, and FIG. 6 is a bag made by mixing a substrate made of sawdust, rice husk, etc. and an aerobic germicide for decomposing garbage. FIG. 7 shows the shape of the measuring cup and scoop, and FIG. 8 shows a sectional view of the hinge portion of the lid.

The garbage processing machine 100 is a garbage processing machine main body O.
The lid 1 attached to the upper part of the main body O constitutes the outside. The garbage processing machine main body O has a garbage input port 6 having an opening at an upper portion thereof, a processing tank 8 for processing the garbage input from the input port 6, and a garbage input into the processing tank 8. A stirring blade 2 for stirring the gas, a motor 10 for driving the stirring blade 2 via a chain, and a ventilation fan 11 for discharging gas generated in the processing tank 8 are provided.

Reference numeral 12 denotes an axis of the stirring blade 2, which is rotated by a motor 10 via a transmission mechanism 13 such as a chain or a belt.

In the bearing portion on the side of the processing tank 8 made of PP resin,
A steel plate reinforcing plate and a combined frame 24 are fixed with screws.
The upper part was fixed by bearing flanges 25, and the motor was directly fixed to the lower part. The agitating shaft 12 vacated from the upper bearing part and the lower motor shaft 26 were connected by a chain, belt or the like.

At the bottom of the processing tank 8, a fan 1 for ventilation is provided.
1, an exhaust port 4 and an intake port 3 are provided. By turning a fan 11, fresh air is sucked into the processing tank 8 through the intake port 3 and gas in the processing tank 8 is exhausted through the exhaust port 4. To be released.

The exhaust port 4 and the intake port 3 are provided with filters 5 respectively.

The processing tank 8 made of PP resin has a rectangular opening at the upper surface, a bottom bulging downward in a semi-circular dome shape, and passing between the front and rear side walls through the center of the arc. The bearing supports a stirring shaft to which a plurality of stirring rods are fixed, so that the outer periphery of the upper opening is shaded, thereby increasing the rigidity of the opening and providing a receiving surface for mounting on the upper opening of the outer case 14. ,
This is a processing tank in which an upper outer peripheral flange is formed.

According to the method of forming the treatment tank 8, a large garbage inlet 6 can be provided, the garbage can be easily charged not only in a triangular corner but also in a bucket, and the outer peripheral surface of the inlet 6 has a seamless structure. As a result, the outer peripheral surface can be easily cleaned.

The garbage input port 6 to the processing tank 8 is covered with a lid 1, and the lid is detachably formed.
In FIG. 8, a U-shaped hinge receiver 1 made of two U-shaped elastic pieces opened upward on a back flange of the processing tank 8.
5 was formed, and a hinge shaft 16 at the lower end of the rear flange of the lid 1 was provided at a position corresponding to this. In the range of about 90 degrees, which is a normal opening / closing operation, the lid can be freely rotated in the U-shaped hinge receiver 15 without coming off, and when opened further, the hinge shaft 16 of the lid rises inside the U-shaped hinge receiver 15 and moves upward. It was detached from the opening.

The hinge shaft 16 at the lower end of the rear flange of the lid 1 is formed integrally with the lid.

Since the lid 1 can be freely attached and detached, it is easier to pump out the upper garbage inlet 6 with a scoop when replacing the old base material. And it became very easy to clean the inside of the processing tank. Since the garbage disposer 100 is presumed to be installed outdoors, attention was paid to the fact that the garbage disposer 100 is most liable to be broken due to ultraviolet deterioration or external force during use, and serviceability was emphasized so that the lid could be easily replaced.

A magnet 30 is attached to the lid 1, and a reed switch is provided inside the processing tank 8 when the lid is closed. When the lid 1 is opened, the switch is turned off, the power of the motor 10 is turned off, and the stirring blade 2 is stopped. Further, the lid 1 is provided with a packing for sealing the space between the outer periphery flange of the egg refuse inlet 6 and the receiving surface.

A planar cord heater 17 is adhered to the outer peripheral surface of the processing tank 8 made of PP resin over a wide area (side surface). Reference numeral 17a denotes a heat-insulating foam sheet that covers the planar cord heater 17. By providing a planar cord heater on the side of the processing tank, the distance from the heater section is short even at the top of the substrate in the processing tank. To As shown in FIG. 5, the planar cord heater 17 spirally winds a heating wire 18 wound in a thin coil shape around a tetron cord 19 as a core, and coats an insulating film 20 thereon. In this example, the sheet is adhered so as to crawl on the aluminum sheet 21.
The heating temperature is monitored by a thermistor (not shown), and the heating temperature can be maintained at a predetermined set value by a temperature control mechanism.

The processing tank 8 contains a base material 22 made of sawdust or rice pulp having poor heat conductivity. The sheet cord heater 17 and the heat-insulating foam sheet 17a must be adhered over a wide area. Can be heated more uniformly.

The electric components such as the planar cord heater 17, the motor 10, and the ventilation fan 11 are turned on and off by a microcomputer built in the controller board 23.
The time of the OFF operation is automatically controlled,
The activity of the bacterium can always be activated, and the garbage disposal performance can be improved.

In FIG. 6, the base material consisting of sawdust and rice hulls and the aerobic bacterium can be shipped by mixing the base material 27 mixed in one bag 28 having a thickness of 60 μm or more. This has made it very easy for consumers to handle. Also, until you open the bag,
The dormant state can be maintained even when the base material and the fungicide are mixed.

In the above configuration, the moisture content of the base material 27 mixed and shipped in one bag is adjusted to 40 to 60% and the mixture is stirred to form a bacterial bed for aerobic bacteria to propagate. After that, it is only necessary to open and close the lid every day and throw garbage into the processing tank 8. The garbage disposer 100 automatically repeats stirring and ventilation at regular time intervals by a microcomputer control incorporated in the controller board 23,
Bacteria can be activated.

The scoop 29 shown in FIG. 7 plays the role of a measuring cup for measuring the amount of water to be charged and a scoop for removing an old base material. When pumping water, hold the scoop 29 vertically and use one of the last lines to prevent water from spilling.
The cup shows about 0.25 L and four cups can pump about 1 L of water.

In the treatment tank 8 having the stirring blades 2 in the center, a substrate made of sawdust and rice hulls and an aerobic fungicide are mixed and shipped in one bag 28 having a thickness of 60 μm or more. The applied base material 27 is loaded.

The mixed substrate 22 is made of lignin, cellulose,
Sawdust, rice husk and rice straw are cut from the main ingredient, which is hardly decomposable such as hemicellulose.Each grain is porous and has voids, and the grain shape is complicated. Because it is uneven and large voids are formed between the grains, it is excellent in moisture control and air permeability even with a small amount of base material, and becomes a home of important bacteria in fermentation and decomposition of garbage .

The garbage is treated in the treatment tank 8 containing the mixed base material 22.
By being stirred inside, the mixed base material 22 is dusted,
The garbage is fermented and decomposed into pieces, and most of the garbage is released as steam and carbon dioxide. In addition, low-molecular-weight decomposition products that become nutrients of plants as solids, that is, compost, are left in the mixed base material 22. The generated gas contains a small amount of gas such as acetaldehyde and trimethylamine which cause a bad smell.

These water vapor, carbon dioxide and other gases are released outside the machine at the stage of ventilation. This operation is automatically continued.

If the processing of such garbage continues for three to six months (depending on the use conditions, the time may vary).
Decomposition products of garbage accumulate, and due to abrasion and water absorption of the mixed base material 22, the mixed base material 22 becomes viscous due to deterioration of air permeability and increase in moisture content, and As a result, it is no longer suitable for the propagation of aerobic bacteria, the fermentation decomposition activity is low, and the temperature of the substrate decreases. Then, the function of the anaerobic bacterium gradually increases in the base material, and a rotten smell appears.

Next, means for solving this problem will be described with reference to FIGS. By attaching a planar cord heater over a wide area on the side surface to efficiently keep the base material with poor heat conductivity, the distance from the heater part is short even in the upper part of the base material in the processing tank. The substrate can be well kept warm, and the activity of the bacteria can be actively maintained for a long period of time. That is, the growth of the bacteria and the fermentation / decomposition activity are sustained and the aerobic property is maintained, so that the life of the mixed base material 22 which is less odorous and inhabits the bacteria is extended. In addition, the substrate made of rice hulls and the like is dried with hot air to a moisture content of 20% or less, and aerobic bacteria are mixed with inorganic particles such as diatomaceous earth and zeolite, and then mixed with the aerobic bacteria agent However, since it is a non-perishable substance, the performance is not degraded even with a single bag of the base material so that consumers can easily handle it.
