In general garbage processing machines, sawdust is put in a processing tank equipped with blades and a ventilator, and a culture substrate such as rice husks (also referred to as “microbe-implanting agent”) is placed therein, and then crushed through a crusher The system that stirs garbage is adopted.

Patent Document 1 describes that bacteria that flow out to the atmosphere and molecules that cause bad odors are sterilized and decomposed by ozone, converted into harmless molecules, and released to the outside air.
JP-A-7-136629

  There is a risk that a person may inhale harmful ozone at a high concentration, which must be taken most care in sterilization and deodorization by ozone. In this respect, the above-described garbage processing machine includes an ozone decomposition catalyst in the exhaust path, and further provides an outside air intake port between the ozone decomposition catalyst and a fan provided in the vicinity of the discharge port, so that fresh air is discharged from outside the apparatus. Is taken out and diluted, and then released to the outside of the machine.

  Therefore, the structure of the safety device is complicated, and the replacement cost of the ozone decomposition catalyst, which is a consumable item, is high, and it cannot be said that the degree of completion is generally high for general household use.

  The present invention has been made in view of the above-described conventional problems, and discharges positive ions and negative ions that are harmless to the human body, so that air exhausted outside the apparatus or air supplied into the processing tank is provided. An object of the present invention is to provide a garbage disposal machine capable of sterilizing floating bacteria inside.

  In order to achieve the above object, the present invention puts a culture substrate and an aerobic bacterium into a treatment tank containing a stirring blade, throws the garbage, and decomposes the garbage by the action of the aerobic bacterium. In the garbage processing machine, an ion generator for generating ions is formed in a passage communicating with the processing tank.

  For example, an ion generator that generates ions can be formed in the vicinity of an outlet that is discharged from the processing tank to the outside of the main body.

  In addition, the culture substrate and aerobic bacteria are placed in a treatment tank that has a built-in stirring blade and communicates with the exhaust device. In the garbage processing machine for decomposing and reducing the volume, the exhaust device is provided with a dust filter at the suction port communicating with the treatment tank, and the ion generating device for generating ions in the ventilation duct constituting the exhaust device is provided. It is characterized by this.

  Alternatively, a culture vessel and an aerobic bacterium are placed in a treatment tank that has a built-in stirring blade and communicates with an air supply device and an exhaust device. In a garbage processing machine that decomposes and reduces the amount of garbage by work, the exhaust device is provided with a dust filter at the suction port that communicates with the treatment tank and generates ions in the ventilation duct that constitutes the exhaust device A device is provided.

  According to this configuration, the culture substrate and garbage are stirred together in the treatment tank, and the garbage is decomposed, but the granular culture substrate that rises with stirring is fed to the intake port of the exhaust device. There is no risk of being sucked into the exhaust system by being blocked by the dust filter provided. Ions generated from the ion generator in the ventilation duct are mixed in the air flow flowing through the ventilation duct, and the floating bacteria in the air are sterilized. Since these ions are completely harmless to the human body, there is no need to worry about leakage outside the machine, and the ions released outside the machine will sterilize airborne bacteria in the vicinity of the garbage processing machine. It also helps to maintain the hygienic condition of outside air.

  Here, in the present invention, ions are generated only when the exhaust fan is rotating.

  Further, the present invention incorporates a stirring blade, puts a culture substrate and an aerobic bacterium into a treatment tank that communicates with an air supply device and an exhaust device, puts garbage into the processing tank, and stirs it together. In a garbage processing machine that decomposes and reduces garbage by the action of aerobic bacteria, the air supply device is provided with a dust removal filter at the discharge port communicating with the treatment tank, and ions are provided in the ventilation duct constituting the air supply device. An ion generating device for generating the above is provided.

  According to this configuration, the culture substrate and garbage are stirred together in the treatment tank, and the garbage is decomposed, but the granular culture substrate that rises with stirring is discharged from the outlet of the air supply device. There is no danger of entering the ventilation duct of the air supply device. The ions generated in the ventilation duct are mixed in the air flowing through the ventilation duct, the floating bacteria floating in the air are sterilized, and there is no possibility that various bacteria are brought into the treatment tank.

  Here, in the present invention, ions are generated only when the air supply fan is rotating.

  The ion generator generates positive ions and negative ions by ceramic creeping discharge, and can sterilize airborne bacteria in the air by the action of these ions.

  According to the garbage processing machine of the present invention, by releasing positive ions and negative ions which are harmless to the human body, sterilization of airborne bacteria contained in the air exhausted outside the apparatus and the air supplied into the processing tank can do.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 is an overall perspective view for explaining the principle of a garbage disposal machine according to Embodiment 1 of the present invention, and FIG. 1 is a garbage processing tank having a blade 2 in the center, in which a culture substrate 3 is contained. The culture substrate 3 is mainly composed of sawdust, biodegradable fiber such as lignin and cellulose, rice husk and the like, each of which is porous, has water absorption and voids, and has a complicated particle shape. Large voids are formed between the particles.

  4 is a shaft of the blade 2 and is rotated by a driving motor 6 via a transmission mechanism 6 such as a chain or a belt. An exhaust device 25 is provided in the upper part of the garbage disposal tank 1. The exhaust device 25 is composed of a suction port 12, an exhaust fan 10, a ventilation duct 26, a small ion generator 27, and a louver 9 provided at the discharge port 13 to the outside of the machine. On the other hand, the garbage processing tank 1 is provided with an air supply port 11 from which fresh air outside the apparatus is sucked. Reference numeral 20 denotes a garbage input into the garbage treatment tank 1, and the garbage input 20 is opened and closed by a hinged lid 21.

  In the present invention, a dust removing filter 30 is provided in the suction port 12 so as not to directly suck the air in the garbage treatment tank 1 where the granular base material is rising in the exhaust device 25.

  Thereby, it arrange | positions so that only the dust-removed air may enter into the exhaust apparatus 25. This is extremely important in preventing the discharge from becoming unstable due to the accumulation of dust on the ceramic creeping discharge surface of the ion generator 27.

  On the other hand, since the base material is soared in the garbage treatment tank 1, the dust removal filter 30 is clogged immediately. This is safe because the dust removal filter 30 can be cleaned by placing it in a position where it can be observed from the garbage inlet 20 and making it detachable.

  The air sucked into the ventilation duct 26 of the exhaust device 25 is mixed with positive ions and negative ions generated by the ceramic creeping discharge type ion generator 27, and due to the strong oxidizing power of the positive ions and negative ions, Airborne bacteria contained in the air are sterilized and released outside the aircraft. In addition, bacteria floating around the garbage processing machine are removed by the positive ions and the negative ions released to the outside of the machine.

  Therefore, the surroundings of the garbage processing machine can be made into a sterilized atmosphere, and the germs sucked into the garbage processing tank 1 from the intake port 11 can be reduced. Therefore, there is no fear that various bacteria enter the garbage treatment tank 1 and the aerobic bacteria propagated on the culture substrate 3 are killed, and the decomposition process of the garbage is performed reliably.

  In addition, since the ion generator 27 is driven only when the exhaust fan 10 is driven, bacteria contained in the air from the garbage processing tank 1 during operation can be removed and sterilized outside the apparatus. Air is released and air purification can be performed efficiently only when necessary.

Here, when the ion generator 27 is driven, a ceramic creeping discharge occurs as described above, and oxygen or moisture in the air is ionized by receiving energy by ionization, and is H ⁺ (H ₂ O) _m which is a positive ion. (M is an arbitrary natural number) and negative ions O ₂ ⁻ (H ₂ O) _n (n is an arbitrary natural number) are generated.

The positive ions H ⁺ (H ₂ O) _m and the negative ions O ₂ ⁻ (H ₂ O) _n adhere to the surface of airborne bacteria and react chemically with hydrogen peroxide (active species). H ₂ O ₂ ) or hydroxyl radical (.OH) is generated. Since H ₂ O ₂ or .OH exhibits extremely strong activity, they can surround and inactivate suspended bacteria.

In addition, hydrogen peroxide (H ₂ O ₂ ) or hydroxyl radical (.OH), which is an active species, oxidizes or decomposes harmful substances to convert chemical substances such as formaldehyde and ammonia into carbon dioxide, water, nitrogen, etc. It can be made substantially harmless by converting it into a harmless substance.

  In addition, positive ions and negative ions have a function to inactivate viruses such as Coxsackie virus and polio virus, and can prevent contamination due to contamination of these viruses. In addition, it has been confirmed that positive ions and negative ions have a function of decomposing molecules that cause odors, and can be used to deodorize spaces.

  In this embodiment, a dust removal filter 31 is provided in the discharge port 14 so that the air in the garbage treatment tank 1 in which the granular culture base material 3 is rising is not directly sucked into the air supply device 35. .

  In the air sucked into the ventilation duct 16 of the air supply device 35, positive ions and negative ions generated by the ceramic creeping discharge type ion generating device 27 are mixed into the air, and are sucked from outside the apparatus by the positive ions and negative ions. Airborne bacteria contained in the air is sterilized and flows into the garbage treatment tank 1. Thereby, there is no possibility that the aerobic bacteria that have entered the garbage treatment tank 1 and propagated on the culture substrate 3 will be killed, and the decomposition process of the garbage is reliably performed.

  In addition, since the ion generator 27 is driven only when the air supply fan 15 is driven, bacteria contained in the air from the garbage processing tank 1 during operation can be removed and sterilized outside the apparatus. The air is released and the air can be purified efficiently only when necessary.
