[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a garbage disposal machine installed outdoors for general households, and more particularly, in a bio-use / extinguishable garbage disposal machine using microorganisms, it prevents decomposition of microorganisms by preventing the input of large garbage. It is intended to prevent processing delays and occurrence of defects, and stop operation and failure.
[0002]
[Prior art]
Conventionally, a garbage processing machine using this type of microorganism has a configuration disclosed in Japanese Patent Laid-Open No. 2001-54776 shown in FIG. The garbage processing machine 1 includes a processing tank 1a, an agitation unit 1b, an air blowing unit 1c, an exhaust unit 1d, and a control unit (not shown).
[0003]
As shown in FIG. 10 and FIG. 11, the garbage G introduced into the processing tank 1a and the medium N such as a chip attached with microorganisms are mixed by the rotation of the stirring blade 1e of the stirring means 1b and adhere to the garbage. Garbage is decomposed and extinguished by microorganisms. In order to discharge the generated carbon dioxide gas and water, outside air is taken in by the blowing means 1c, blown to the treatment tank 1a, and exhausted to the outside from the exhaust means 1d.
[0004]
[Problems to be solved by the invention]
As described above, the garbage G and the medium N to which microorganisms adhere are agitated and mixed by the stirring blade 1e. If the garbage G is large, the stirring blade 1e is entangled or the tip of the stirring blade 1e and the inner wall of the treatment tank The garbage G is easily clogged in the gap, and as a result, the stirring blade 1e cannot rotate, causing a failure.
Furthermore, in order to decompose garbage by microorganisms, if the surface area of garbage to which microorganisms adhere is increased as much as possible, the decomposition action can be performed quickly. In other words, if the garbage is large, the surface area becomes small and the decomposition process takes a long time, and it is not decomposed well, resulting in anaerobic fermentation and a source of malodor.
[0005]
For this reason, it is necessary to cut the garbage finely and then put it into the processing machine. In the conventional garbage processing machine, it is added in the instruction manual that the garbage is cut after being cut into small pieces. However, the user often throws large garbage without cutting it, and the above-described problems occur.
Although there is a method of installing a crushing device at the inlet, the processing machine becomes larger, the manufacturing cost becomes expensive, and the cost of running and maintenance is also high, and the crushing device is installed in the household garbage processing machine. It has not been.

[0017]
A cover plate 20 is slidably attached as an intake air amount adjusting means to the intake port 11a-1 at the lower part of the fan built-in portion 11a. If the cover plate 30 is slid with the knob 30a, the intake area of the intake port 11a-1 can be increased or decreased steplessly.
A lower opening between the shielding plate 15 disposed opposite to the cross flow fan 14, the front end, and the outer tub 11 is used as a blower outlet 26, and blown air blown from the blower outlet 26 blows into the decomposition tank 13 from above. I am doing so.
[0018]
After the internal vent 13a is provided in the flange portion 13c on the side facing the blower outlet 26, exhaust gas containing carbon dioxide and moisture is circulated from the internal vent 13a through the vent circulation space S through the internal vent 13a. The air is exhausted outward from the exhaust port 11b provided on the side opposite to the vent hole 13a and below the mounting side of the cross flow fan 14.
[0019]
The heater 19 attached to the shielding plate 15 has a coil-shaped heating wire in the pipe, and a manual switch 24 for turning the heater 19 on and off is attached to the upper wall of the fan built-in portion 11a. In addition, a manual switch 23 for the fan that switches the rotational speed of the motor M that drives the main shaft 14a of the crossflow fan 14 in two steps of strength and weakness is provided in parallel with the manual switch 24 for the heater.
[0020]
As shown in FIG. 1 and FIG. 5, the stirring means 16 attached in the decomposition tank 13 has six stirring blades 16a projecting radially from the shaft portion 16b, and a coil spring is wound around the tip of each stirring blade 16a. A spring portion 16c is provided. Both ends of the shaft portion 16b are rotatably supported by the bearing portion 11d of the decomposition tank 11, and one end of the shaft portion 16b protrudes into a driving chamber 25 provided between the decomposition tank 13 and the outer tank 11, and a pulley 28 is provided at the protruding portion. Is attached. A drive shaft 21a of the motor 21 is protruded from the lower portion of the drive chamber 25, a pulley 21b attached to the drive shaft 21a and the pulley 28 are connected via a drive belt B, and the stirring blade 16a is rotated by the motor 21. doing.
In addition to the belt B, a transmission means such as a chain may be used as the rotation transmission means for the motor drive shaft 21a and the shaft portion 16b.
[0021]
When the motor 21 inserts the power plug 17a of the power supply means 17 into an outlet (not shown) and closes the lid 12, the motor 21 is automatically turned on and is driven for a set required time, and the stirring blade 16a is driven. It is set to be rotated and then stopped for a required time, and repeated to be driven and stopped again. The cross flow fan 14 is also set to automatically rotate when the lid 12 is closed. That is, when the lid 12 is closed, the stirring means 16 is rotated and the air is sent to automatically operate.
[0022]
Next, operation | movement of the garbage processing machine 10 of this invention is demonstrated.
A medium N2 to which microorganisms adhere is introduced into the decomposition tank 13 from the inlet 11c of the outer tank 11. In this embodiment, a cryogenic microorganism that is active at 10 ° C. is attached to a medium N2 made of wood chips and sawdust.
[0023]
When the garbage G is generated, the lid 12 is opened and charged from the charging port 11a. The introduced garbage G passes through the cover net 20, and only the garbage G smaller than the mesh gap is introduced into the decomposition tank 13 through the cover net 20. The garbage G that does not pass through the gap remains as it is placed on the cover net 20 as shown in FIG. Therefore, the garbage G that has not passed through the cover net 20 is taken out and cut to a size that can pass through the cover net 20, and then re-injected into the inlet 11 a, and the stirring vessel 13 has a stirring blade. It is possible to prevent large garbage G that is entangled with 16b from being thrown in.
[0024]
After throwing in the garbage G, the lid 12 is closed. When the lid 12 is closed, the cross flow fan 14 rotates and the agitation unit 16 also rotates, and the raw garbage G and the medium N to which the microorganisms adhere are agitated and mixed.
[0025]
By rotating the cross flow fan 14, external air is sucked from the air intake port 11a-1, heated by the heater 19, and then blown into the decomposition tank 13 from the blower outlet 26 and stirred. The water of the medium N to which water adheres is uniformly evaporated. At that time, since the size of the garbage G is reduced, the surface area of the whole garbage increases, and the amount of microorganisms attached to the garbage can be increased. Can do.
Moreover, since the blower outlet 26 is directed downward, the blown-out air can be directly blown into the decomposition tank 13, and the air is sufficiently distributed to the garbage G and the medium N to be stirred and mixed. be able to.
[0026]
The carbon dioxide gas generated when the garbage G is decomposed by the evaporated water or microorganisms will cause anaerobic fermentation of the medium N in the decomposition tank 13 unless it is discharged to the outside. In the present invention, the evaporated water or carbon dioxide gas is sent out from the internal vent 13a to the vent circulation space S, passes through the vent circulation space S, and is discharged to the outside through the exhaust port 11b.
[0027]
The stirring means 16 is provided with a spring 16c having the required elasticity and rigidity at the tip of the stirring blade 16a, so that the shaft portion 16b rotates to stir and mix the garbage N1 and the medium N2 to which microorganisms adhere. When the garbage is clogged between the tip of the stirring blade 16a and the inner wall of the decomposition tank 13, the spring 16c bends, and the rotation of the stirring blade 16a due to the clogging with the garbage can be prevented. Moreover, since rigidity is provided to the spring 16c, the garbage and the medium can be stirred with a strong force.
The stirring means 16 is intermittently driven, rotates for 5 minutes at an interval of 25 minutes, and also stops when the lid 12 is opened.
[0028]
The cross flow fan 14 is operated continuously for 24 hours, and the air volume is adjusted by switching the rotational speed with the fan manual switch 23 or finely adjusting the intake air amount with the cover plate 20, and the manual switch 24 for the heater. By turning the heater 19 on and off, the humidity in the decomposition tank 13 can be kept moderate (water content of about 40%).
[0029]
That is, when the moisture content of the mixed garbage N1 and the medium N2 to which the microorganisms adhere becomes large (about 60% or more), the heater 19 is turned on and the cross flow fan 14 is also strong. At the same time, by further sliding the cover plate 20 to increase the area of the suction port 11a-1, the inside of the decomposition tank 13 can be quickly dried by increasing the air flow rate.
On the other hand, when the moisture content is small (about 20% or less), the heater 19 is turned off and the cross flow fan 14 is weakened, and the cover plate 20 is further slid to suck the inlet 11a. By reducing the area of −1, it is possible to reduce the amount of blown air and prevent the moisture content in the decomposition tank 13 from being reduced as required.
[0030]
Further, since the microorganisms used in the garbage processing machine 10 of the present invention are low-temperature decomposing microorganisms, the temperature in the decomposition tank 13 may be kept at about 10 ° C. at which the low-temperature decomposing microorganisms are active. It is not necessary to use a high output one, and the running cost can be reduced.
[0031]
Note that the present invention is not limited to the above embodiment, and the cover net 20 is not limited to a shallow bottom shape, but may be a flat plate shape as shown in FIG. Further, while a garbage cutting blade is projected on the lower surface side of the cover net that is not touched by the user's hand, a protrusion that can be inserted into the gap of the cover net 20 is provided on the lid side so that the garbage can be moved downward. It is good also as a structure which can be pushed in and can cut | disconnect garbage with the said cutting blade.
Furthermore, it can also be suitably used when a microorganism that operates at a high temperature is used as the microorganism.
[0032]
【The invention's effect】
As is clear from the above description, according to the present invention, since a garbage cover net is provided and large garbage is not put into the decomposition tank, the operation is stopped because large garbage is entangled with the stirring blade. , It is possible to prevent a failure from occurring. In addition, because the garbage is made smaller, the overall surface area of the garbage can be increased and the adhesion rate of microorganisms to the garbage can be increased. Can be done quickly. Therefore, it is possible to prevent bad smell from occurring due to anaerobic fermentation without being decomposed well.
[0033]
Furthermore, taking out large pieces of garbage left on the cover net and shredding it is a cumbersome operation for the user, so the user can make a habit of shredding large raw garbage in advance before putting it in. Therefore, it has an advantage from the point of giving a consciousness that large garbage should not be thrown into the garbage disposal machine.
