TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a garbage disposal apparatus for decomposing garbage using the power of microorganisms, and more particularly to a structure for deodorizing and exhausting odors generated in a garbage disposal tank.
[0002]
[Prior art]
Background Art Conventionally, garbage containing organic matter and water has been decomposed (fermented) to the extent that it does not affect the environment by using the power of microorganisms, and there is known a garbage disposal apparatus that performs this treatment. ing.
[0003]
This garbage disposal device is filled with wood chips called biochips as garbage disposal material in the garbage disposal tank, and puts garbage into the garbage disposal tank through the input port provided in the garbage disposal tank. The garbage is fermented and decomposed by the action of microorganisms living in the garbage disposal tank.
[0004]
However, when the garbage is decomposed in the garbage disposal tank, an odor is generated in the garbage disposal tank, so it is necessary to deodorize and exhaust the odor, and a structure as shown in FIG. 7 is employed. To deodorize. A deodorizer 1 is disposed outside the garbage processing tank. The deodorizer 1 is formed by housing a catalyst 3 such as a platinum catalyst and a heater 4 for heating the catalyst 3 in a casing 2. . The inside of the garbage disposal tank and the upper end of the casing 2 of the deodorizer 1 are communicated with each other by an exhaust feed pipe 5, and an exhaust fan 6 is attached to the exhaust feed pipe 5. When the exhaust fan 6 is driven, the air containing the odor in the garbage disposal tank is sent into the casing 2 of the deodorizer 1 through the exhaust feed pipe 5, and the catalyst 3 (200 to 200) is heated by the heater 4. (Heated to a temperature of about 250 ° C.), and the air is deodorized and the deodorized air is exhausted.
[0005]
[Problems to be solved by the invention]
However, in the case of the deodorizer 1 having the above-described structure, when the exhaust fan 6 is stopped due to the power being removed during the deodorizing operation, the high-temperature air in the casing 2 is discharged by the ascending airflow so that the exhaust gas flows upstream of the exhaust flow. There is a possibility that the exhaust gas may flow backward to the pipe 5, the exhaust fan 6, and the like, and the exhaust feed pipe 5, the exhaust fan 6, and the like may be heated by high-temperature air. For this reason, there is a problem that a safety design such as forming the exhaust feed pipe 5 and the exhaust fan 6 from a heat-resistant material is required.
[0006]
The present invention has been made in view of the above points, and it is an object of the present invention to provide a garbage disposal apparatus that can ensure safety by preventing high-temperature air from flowing backward even when power is removed during a deodorizing operation.

[0016]
In the deodorizing operation, when the heater 4 is energized to heat the catalyst 3 and the exhaust fan 6 is driven to send exhaust gas from the exhaust feed pipe 5, exhaust gas rectified by the rectifying plate 10 passes through the catalyst 3, The heat-deodorized and deodorized exhaust gas is diluted in the dilution chamber 22, and the temperature-reduced exhaust gas is exhausted to the outside. At this time, the exhaust gas sent into the casing 2 from the exhaust feed pipe 5 is rectified by the rectifying plate 10, passes through the catalyst 3 uniformly, and is efficiently deodorized. When exhaust gas flows from the exhaust feed pipe 5 into the casing 2, dust may be deposited on the flow straightening plate 10, but in the case of the present invention, the dust is collected in the concavely curved portion 12, and the dust is collected from the gap 11. The dust does not fall down and accumulate on the current plate 10. When the power is turned off during the deodorizing operation as described above, the high-temperature air in the casing 2 rises due to the rising airflow. This high-temperature air is stored in the buffer section 9 at the upper end of the casing 2. Does not flow toward the exhaust feed pipe 5. For this reason, it is not necessary to make the exhaust feed pipe 5, the exhaust fan 6 and the like heat resistant. The high-temperature air accumulated in the buffer unit 9 is radiated to the outside from the upper part of the casing 2.

Then, the temperature fuse 31 is attached along the outer surface of the casing 2 of the deodorizer 1, and the power supply is cut off when the deodorizer 1 is abnormally overheated.
[0018]
By the way, conventionally, when attaching the thermal fuse 31, a structure as shown in FIGS. 8 and 9 has been adopted. A long recess 40 is provided in the outer surface of the casing 2 in the horizontal direction, a mounting member 33 ′ is mounted on the outer surface of the casing 2, and a portion of the thermal fuse 31 is pressed by a holding member 34 having a substantially V-shaped cross section of the mounting member 33 ′. The portion of the thermal fuse 31 was held between the holding piece 34 and the depression 40. In the conventional deodorizer 1, the depression 40 is provided for rectification and the mounting of the thermal fuse 31. However, in the deodorizer 1 of the present invention, the depression 40 cannot be formed because the width L of the deodorizer 1 is reduced. Further, since the current plate 10 is provided inside, the depression 40 is unnecessary.
[0019]
Therefore, in the present invention, the following structure is adopted in order to eliminate the recess 40 and securely attach the same. The outer tube 32 in a portion having the thermal fuse 31 is attached to the outer surface of the casing 2 along the horizontal direction. However, since the width L of the deodorizer 1 is small, both ends of the outer tube 32 in the longitudinal direction are lateral to the deodorizer 1. Protrude into. Then, it attached to the deodorizer 1 using the attachment 33 of the following structures. As shown in FIGS. 5 and 6, the attachment 33 is formed in a plate shape elongated in the left-right direction by a sheet metal or the like, and a holding piece 34 having a substantially L-shaped cross section is provided at the center. At both ends in the direction, receiving pieces 35 having a substantially U-shaped cross section are provided to face the holding pieces 34. As shown in FIG. 4, when mounting the thermal fuse 31 with the mounting tool 33, the mounting tool 33 and the portion of the thermal fuse 31 are arranged in parallel, and the portion of the thermal fuse 31 is held between the holding piece 34 and the receiving piece 35. The holding piece 34 is brought into contact with the longitudinal center of the outer tube 32 at the portion where the thermal fuse 31 is located, and the receiving piece 35 is brought into contact with both ends of the outer tube 32 so that the outer tube 32 is pressed against the holding piece 34 and the receiving piece 35. And the attachment 33 is fixed to the casing 2 by the fixing member 36. By attaching the portion of the thermal fuse 31 with the fixture 33 in this manner, it is possible to attach the thermal fuse 31 without pulling the lead wire 30 so that the portion of the thermal fuse 31 does not come off even if the recess 40 is not provided unlike the related art. it can.
