Description

  TECHNICAL FIELD The present invention relates to a garbage disposal apparatus for decomposing or drying garbage discharged from a general household or business establishment as a soot, and more specifically, a tank provided in a lid body that closes an upper surface opening of a treatment tank. The present invention relates to a garbage disposal apparatus for drying the contents of a treatment tank by an internal fan.

  As processing methods of the garbage processing apparatus, a microbial decomposition method and a high-temperature drying processing method are generally known. The microbial decomposition treatment system is a method for decomposing garbage by the action of microorganisms. As a general garbage treatment apparatus of this kind, a treatment tank into which garbage is introduced and an upper surface opening of the treatment tank are provided. A lid that can be freely opened and closed to be closed; a treatment material that supports microorganisms filled in the treatment tank; a heating means that heats the contents of the treatment tank; and a stirring means that agitates the contents of the treatment tank; And a ventilation means for ventilating the air in the treatment tank. Here, the treatment material is made of a wood chip called a biochip carrying microorganisms. Then, the heating means, the stirring means, and the ventilation means are controlled and operated, so that the moisture content of the contents of the treatment tank is 30 to 60% and the temperature of the contents of the treatment tank is 20 to 60 ° C. as shown in FIG. In this way, the activity of microorganisms is increased and the garbage put into the treatment tank is aerobically decomposed to reduce the volume of garbage. The high-temperature drying treatment method heats the garbage, which is the contents of the treatment tank, at a high temperature of 100 ° C. or higher as shown in FIG. The volume of garbage is reduced by drying to about 10% in a short time.

  In the above microbial decomposition treatment method, there is a problem that a decomposition odor such as ammonia is generated during the decomposition treatment, and in the high temperature drying treatment method, when the garbage is heated to 100 ° C. or more, the garbage is In recent years, a new method different from the above-mentioned microbial decomposition treatment method and high-temperature drying treatment method has occurred due to the problem that the lipid peroxide and protein contained in the product are denatured at high temperature and a burning odor represented by aldehydes is generated. A garbage disposal apparatus for treating garbage is also proposed. This garbage disposal apparatus includes, for example, heating means, stirring means, and ventilation means, as in the above-described microbial decomposition method, and maintains the temperature of the contents of the treatment tank at 90 ° C. or lower as shown in FIG. And the moisture content of the contents is controlled to 20% or less at which microorganisms cannot propagate, thereby suppressing the generation of microbial decomposition odor and burnt odor. This new type of garbage processing equipment has a high moisture content in the garbage immediately after it is put in, so it is filled with a treatment material consisting of a particulate or chip-like dispersion material with hygroscopicity. The moisture content of the garbage containing a large amount of water immediately after the addition is reduced by stirring the garbage introduced immediately after and the treatment material.

  In addition to this, in order to further enhance the drying capacity of the garbage disposal apparatus as described above, one end of the lid body that closes the upper surface opening of the treatment tank can be freely opened and closed to the lid body attachment portion via a hinge portion. There is also known a garbage disposal apparatus which is attached to the lid body and is provided with a fan in the tank on the lid body. The in-tank fan of this garbage disposal apparatus is provided with the in-tank fan in a portion of the lower surface portion of the lid main body whose center of gravity is located on the extension line of the central axis of the processing tank and overlapping the center of gravity of the lid main body in plan view. The air is blown downward from the fan in the tank, and the blown air promotes the drying of the contents at the center of the upper part of the treatment tank, thereby improving the drying efficiency of the garbage processing apparatus. (For example, Patent Document 1 discloses a garbage disposal apparatus having an in-tank fan disposed on a lid body as described above).

  By the way, this type of in-tank fan is operated in a high-temperature and high-humidity environment that is in the same environment as the inside of the processing tank, so it generally has a complicated structure and is heavy. Since this heavy fan in the tank is disposed in a portion overlapping the center of gravity of the lid body, the center of gravity of the entire lid consisting of the lid body and the fan in the tank is on the extension line of the central axis of the processing tank, That is, it is located at a position far away from the hinge part, and this increases the moment centered on the hinge part due to the weight of the lid, and the burden on the user when opening and closing the lid is large. .

  In addition to the above, there is also known a garbage disposal apparatus in which a tank fan is provided at a position outside the center of gravity of the cover body on the hinge part side of the cover body and air is blown downward from the tank fan. Since the center of gravity of the entire lid is positioned closer to the hinge than the center of gravity of the lid body, the burden on the user when opening and closing the lid is light (for example, Patent Document 2).

However, this is because the air is blown downward from the fan in the tank provided on the hinge side of the center of gravity of the lid body, that is, on the extension line of the central axis of the processing tank. The inside of the inside of the treatment tank that is difficult to dry could not be dried, and the drying efficiency was low.

  Further, as described above, the suction port 13 is formed at a position away from the blowout port 14 toward the hinge portion 9, and the suction port 13 is opened toward a position away from the upper hinge portion 9 in the processing tank 2. Since the air at the hinge portion 9 side having a relatively high temperature in the upper part inside the processing tank 2 can be sucked from the suction port 13, the high temperature air is circulated in the processing tank 2. As a result, the drying efficiency of the garbage disposal apparatus 1 is further improved. Here, of the upper part in the processing tank 2, the temperature of the air on the hinge part 9 side is higher than the others. When the lid 4 is opened and closed, outside air is present in the vicinity of the hinge part 9 inside the processing tank 2. When the center of gravity of the lid 4 is positioned closer to the hinge part 9 than the center of gravity of the lid body 10 as described above, the sealing property on the hinge part 9 side of the upper surface opening 3 of the treatment tank 2 is low. Because it becomes high.

  In addition, although the garbage processing apparatus 1 of this example shall dry-process garbage by the new system shown in the prior art example, even if it treats garbage by a microbial decomposition processing system or a high-temperature drying processing system, Be good. In this example, the in-tank fan 11 is a sirocco fan. However, a kumatori motor or an axial fan may be used. Moreover, although the example which provided the said fan 11 in the tank in the inside of the lid | cover main body 10 was shown in this example, the fan 11 in a tank may be provided in the lower surface of the lid | cover main body 10, and the fan 11 in a tank is used as a lid | cover main body. It is assumed that the in-tank fan 11 may be disposed inside the processing tank 2 while being suspended from the apparatus 19.
