  However, in the configuration of the conventional warm air type garbage processing machine, the hot air to be heated and dried flows only on the surface of the garbage 2 and is difficult to reach the garbage 2 near the bottom surface of the garbage storage container 3. The problem was that the drying performance could not be improved. In particular, when a large amount of garbage 2 is thrown in, the garbage 2 is present in the vicinity of the blower fan 8, so when the warm air rises up the center of the garbage storage container 3 and returns to the drying fan 8. The debris and powder of the garbage 2 are wound up, and the debris and powder of the garbage 2 are attached to the fan cover 10. Since these adhesions reduce the convection formed in the garbage storage container 3 by the blower fan 8, the drying performance is lowered.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a cross-sectional view of a garbage disposal machine according to Embodiment 1 of the present invention. In FIG. 1, the main body 40 of the garbage processing machine in this Embodiment is provided with the outer container 11 which accommodates the garbage storage container 12 which accommodates garbage etc. so that attachment or detachment is possible. The garbage storage container 12 may be made of resin or metal, but the metal can be heated more efficiently, so that the drying performance is more excellent. A fixed blade 13 is provided on the inner wall of the garbage storage container 12, and a rotary blade 14 that rotates while intersecting with the fixed blade 13 is connected to the center shaft 16. The center shaft 16 is detachably connected to a rotating shaft 18 by a connecting portion 17 provided at the bottom of the outer container 11, and the rotating shaft 18 is driven by a drive motor 15.

  The fixed blade 13 and the rotary blade 14 constitute pulverization and stirring means for pulverizing and stirring the garbage and the like inside the garbage storage container 12. Reference numeral 20 denotes a heater serving as a heating means for heating the garbage storage container 12, and is disposed at the lower part of the garbage storage container 12.

  In the present embodiment, the heater 20 is composed of a ring-shaped electric heater. However, if the heater 20 is composed of a combination of a metal garbage storage container 12 and an electromagnetic induction coil (not shown), direct garbage storage is performed. Since the container 12 can be induction-heated, the drying performance is further improved. 24 is a lid provided on the main body 40 so as to be openable and closable. A back lid 27 is provided inside the lid 24, and the opening 12 a of the garbage storage container 12 is sealed with a packing 25 attached to the back lid 27. Yes. The back cover 27 is provided with an intake port 26 for introducing outside air and an exhaust port 30 for discharging steam generated from the garbage 32.

  On the upper part of the garbage storage container 12, a blower fan 19 that sends air into the garbage storage container 12 is arranged via a shaft of a blower motor 21 attached to the upper part of the back cover 27. The periphery of the blower fan 19 prevents the garbage 32 from coming into contact with the blower fan 19 and is surrounded by a fan cover 22 having a large number of openings (not shown). Is sent into the garbage storage container 12 through the opening on the outside of the fan cover 22, and air is sucked from the opening on the inside of the fan cover 22 to cause convection in the garbage storage container 12. .

  An exhaust passage 23 is connected to the discharge port 30 and is connected to a deodorizing device 31 that deodorizes the odor of the exhaust to form an exhaust passage. On the exhaust side of the deodorizing device 31, suction means including an exhaust fan 28 and an exhaust fan motor 29 is arranged, and the steam in the garbage storage container 12 is sucked by the exhaust fan 28 and discharged to the outside. It is like that.

  The operation of the garbage disposal machine in the present embodiment configured as described above will be described below.

  The garbage 32 put into the garbage storage container 12 is agitated by the rotary blade 14 that performs forward and reverse rotations intermittently and pulverized by the rotary blade 14 and the fixed blade 13. The garbage storage container 12 heated by the heater 20 heats the garbage 32 and the like, and steam is generated from the heated garbage 32 and the like. The water vapor containing the generated odor is sucked by suction means comprising an exhaust fan 28 and an exhaust fan motor 29, and is introduced into the deodorization device 31 through the discharge port 30 and the exhaust passage 23 in the upper part of the garbage storage container 12.

  The steam containing the odor introduced into the deodorizing device 31 is discharged outside after the odor is removed by the deodorizing device 31. Fresh air is always sucked into the garbage storage container 12 from the air inlet 26, and the steam during drying is smoothly sucked into the deodorizing device 31 side, so that the reattachment of odor to the dry waste is also suppressed. . Therefore, there is no off-flavor during drying, it is easy to throw away, and since the water activity is reduced after drying, it does not rot or mold. Therefore, it can be converted into garbage that is easier to handle and easier to process than the garbage 32.

  Here, in the initial operation period from 5 minutes to 30 minutes from the start of operation, the rotation time of the rotary blade 14 is lengthened, the rotation speed is increased, or the rotation cycle is shortened, so that the garbage 32 is crushed and volume-reduced in the initial operation period. By liquefying, the contact area with the bottom surface of the garbage storage container 12 is increased, and heat can be efficiently transferred to the garbage 32. After the garbage 32 is reduced in volume and liquefied, the rotation time of the rotary blade 14 is shortened, the rotation speed is slowed, or the rotation cycle is lengthened to reduce noise generated when the rotary blade 14 is rotated, and the drive motor 15. Can be reduced.

  Further, in the present embodiment, since the blower fan 19 is stopped or the rotation speed thereof is slowed in the initial stage of operation, that is, while the garbage 32 is close to the blower fan 19, the garbage to the fan cover 22 is discarded. The adhesion of 32 can be suppressed, and the deterioration of the drying performance can be prevented.

  Further, as the garbage 32 is dried, the liquefied garbage 32 is solidified and heat is not easily transmitted from the garbage storage container 12 to the garbage 32, but the wind generated by the blower fan 19 is generated in the garbage processing container 12. Since it descends while turning along the wall surface, it becomes warm air by the heat of the heated garbage storage container 12 and flows on the surface of the garbage 32 and is not in contact with the garbage storage container 12. Since the surface of the garbage 32 can be heated, the drying performance can be maintained even in a state where the garbage 32 is being dried, and a garbage disposal machine having excellent drying performance can be provided.

  As described above, the garbage processing machine according to the present invention is intended to improve and maintain the drying performance, and is optimal as a garbage processing machine that mainly treats garbage generated in a home kitchen.
