The first means of the present invention operates as follows. The food waste put in the food waste storage container is heated and dried by the heating means while being crushed and stirred. Water vapor containing odorous components from raw garbage is condensed in the condensing part and accumulated in the condensed water container. On the other hand, the water vapor containing the odorous components that cannot be completely condensed is guided to the deodorizing device and the odorous components are purified. The crushed and dried food waste remains in the inner container, but since the bulk is reduced and the water activity is reduced due to drying, even if it is put in the food waste storage container as it is, it will rot or mold. Will never occur. Therefore, the raw garbage can be successively put on the dried raw garbage and dried until the raw garbage storage container is full.

The sixth means of the present invention has a structure in which the rotary blade and the rotary shaft are detachably engaged with each other, so that the food waste container can be easily cleaned.

In the seventh and eighth means, since the rotary blade is formed of plastic or covered with plastic, non-adhesive plastic does not act on the rotary blade at the time of crushing and drying, and the raw garbage does not adhere to the rotary blade. However, it can be easily wiped off.

The ninth and tenth means are constructed so that the water vapor generated from the garbage storage container is condensed in the condensing part and stored in the condensed water collecting container. There is no need for processing. In addition, the water condensed in the condensing unit is stored in the condensed water collecting container, which can be detected by the detection device, and the deodorizing device is arranged in the vicinity of the condensed water collecting container, so during operation. Condensed water is prevented from freezing due to the heat of the deodorization device, and even if the outside temperature changes, the detection device operates normally so that water does not overflow from the condensed water collection container.

In the eleventh and twelfth means, hot air is circulated throughout the food waste container by a stirring fan provided on the lid above the food waste container. Further, since the shaft of the drive motor that penetrates the lid is provided with a bearing that covers the penetrating portion and has a grease reservoir, the gap between the shaft and the penetrating portion can be set with a margin, so that vibration and thermal expansion It can cope with gap fluctuations, yet it does not leak steam.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIG.
This will be described with reference to FIG.

In FIG. 1, reference numeral 1 denotes a heat insulating container (in FIG. 1, a vacuum heat insulating container having an inner wall and an outer wall and having a space between them is evacuated) is shown. It is a container. A fixed blade 4 and a rotary blade 5 are provided in the raw garbage storage container 2 as means for crushing and stirring raw garbage. The fixed blade 4 is provided on the inner wall of the food waste storage container 2, and the rotary blade 5 is provided on the inner bottom portion of the food waste storage container 2 and is fixed to the rotary shaft 6 protruding from the bottom surface of the food waste storage container 2. . Above the food waste container 2, a heater 8 is provided as a food waste heating means, and a stirring fan 9 for evenly feeding the heat of the heater 8 into the food waste container 2. Reference numeral 10 is a motor for driving the stirring fan.

Further, a condensing section 11 for condensing water vapor generated from food waste is arranged on the outer peripheral portion of the heat insulating container 1.
A blower fan 12 for cooling the outer surface is installed outside the condenser 11. The heat insulating container 1 and the food waste container 2 are installed in an inclined state in this embodiment so that they rotate integrally. Therefore, the rotation of the drive motor 14 is driven by the drive shaft 1 via the reduction gear 15.
6, the drive shaft 16 has a two-axis structure, that is, an outer shaft 16a and an inner shaft 16b.
The outer shaft 16a is engaged with the heat insulation container 1 by the cab ring 17a, and the heat insulation container 1 and the garbage storage container 2
To rotate. Further, the inner shaft 16b is a coupling 17
It engages with the rotary shaft 6 by b and rotates the rotary blade 5.
The outer shaft 16a and the inner shaft 16b of the drive shaft 16 rotate in different directions.

At the bottom of the condensing section 11, the condensed water outflow pipe 1
8. The exhaust pipe 19 is connected. At the tip of the condensed water outflow pipe 18, a condensed water container 20 for accumulating condensed water is detachably provided. A deodorizing device 21 is provided on the exhaust pipe 19. Reference numeral 22 is a main body of the garbage processing machine, and 23 is a lid accommodating the food waste heating means. The lid 23 is supported by a hinge 24, and can be freely opened and closed on the garbage processing machine body 22, the packing is sandwiched, the lid 23 and the garbage processing machine body 22 are fixed by the latch type handle 25, and the food waste container 2 is sealed. It becomes a state.

Next, as shown in FIG. 3, the fixed blade 4 and the rotary blade 5 rotate in mutually opposite directions to make intermittent rotation in which rest and rotation are repeated, and the rotation direction is reversed at each rotation. Controlled. The fixed blade 4 and the rotary blade 5 are the drive shaft 1
6 has a biaxial structure, and the outer shaft 16a and the inner shaft 1
Since 6b is different from each other, the rotating blades 5 and the garbage disposal container 2 are different in rotation direction from each other, and therefore the rotating blades 5 and the fixed blade 4 provided in the garbage disposal container 2 are opposite in rotation direction to each other. Direction. By doing so, the food waste stored in the food waste container 2 is scooped up by the fixed blade 4 and stirred, and is crushed between the fixed blade 4 and the rotary blade 5. Moreover, since the fixed blade 4 and the rotary blade 5 rotate in mutually opposite directions, the relative speed between the fixed blade 4 and the rotary blade 5 is increased, and the crushing ability of food waste can be enhanced.

When the fixed blade 4 and the rotary blade 5 are continuously rotated, starchy food waste such as rice has a strong stickiness,
It becomes like a rice cake and the inside becomes difficult to dry. Therefore, by intermittently performing rotation for a short time (for example, rotation for 5 seconds and rest for 60 seconds), it is possible to prevent starchy food waste from becoming rice cake-like. Further, if the rotation is continued only in one direction, garbage will be easily clogged between the fixed blade 4 and the rotary blade 5, and the rotary blade 5 will be easily locked. Therefore, the rotating blade 5 is prevented from being locked by changing the rotation direction every time the rotation is intermittently performed.

Further, a crushing blade 26 for crushing the garbage bag is vertically provided on a part of the rotary blade 5.
The rotary blade 5 is mainly for crushing and stirring raw garbage. The raw garbage is put into the raw garbage storage container 2 while being put in the raw garbage storage bag (polyethylene bag or the like), and pulverized and dried. In this case, since the rotary blade 5 rotates, the crushing blade 26 provided on the rotary blade 5 also rotates at the bottom of the garbage bag and crushes the bag. Then, the garbage in the bag spills out of the bag and is crushed by the tip of the rotary blade 5 and the fixed blade 4. In this way, the raw garbage can be put into the raw garbage storage container 2 in a state where it is put in the raw garbage storage bag, and the usability of the garbage disposal is improved.

Further, the rotary blade 5 is configured to be detachably engaged with the rotary shaft 6. That is, as shown in FIG. 2, the tip portion of the rotary shaft 6 has a substantially D-shaped cross section, and a thin groove portion 27 is formed in a part thereof. Similarly, a hole having a substantially D-shaped cross section is also provided in the central portion of the rotary blade 6, and a protrusion 29 urged by a spring 28 projects into the hole. When the rotary blade 5 is inserted into the tip of the rotary shaft 6, the protrusion 29 fits into the groove 27,
When the rotary blade 5 and the rotary shaft 6 are engaged with each other and the rotary blade 5 is pulled by hand, the rotary blade 5 can be easily removed. Therefore, when the inside 2 of the food waste container is dirty or the rotary blade 5 is burned with the garbage, the rotary blade 5 can be removed to wash the food waste container 2 and the rotary blade 5 for cleaning. It is designed to be easy to operate.

The surface of the rotary blade 5 is made of plastics. That is, when the rotary blade 5 is made of metal, the blade portion at the tip is left and the other surface is covered with plastics (broken line portion in FIG. 2).
The rotary blade 5 may be entirely made of plastics. Since plastics have higher non-adhesiveness than metals, this structure hardly causes food scraps to be burned onto the rotary blade 5 during pulverization and drying, and even if they adhere, they can be easily wiped off and cleaned more. Easier to do.

If the fixed blade 4 has the same structure as the rotary blade 5, it is possible to more effectively eliminate the seizure of food waste.

The operation of the garbage processing machine configured as described above will be described. The raw garbage put into the raw garbage storage container 2 is crushed intermittently in mutually opposite directions and between the rotary blade 5 and the fixed blade 4 whose rotational directions are reversed. At the same time, the heater 8 heats the heat, and the stirring fan 9 evenly diffuses the heat into the food waste container 2. Further, the raw garbage storage container 2 rotates in an inclined state, and at this time, the fixed blade 4 provided on the inner wall of the raw garbage storage container 2 scoops the raw garbage, so that the crushed raw garbage is stirred. Water vapor containing odorous components is generated from raw garbage and flows into the condensation section 11 outside the heat insulating container 1 through the opening of the raw garbage container 2.

Then, the water vapor is condensed by the blower fan 12 in the condensing section 11 and condensed, and the condensed water outflow pipe 18
It collects in the condensed water container 20 through. On the other hand, the water vapor containing the odorous component that cannot be completely condensed is guided from the exhaust pipe 19 to the deodorizing device 21 and the odorous component is purified. The crushed and dried food waste remains in the food waste container 2, but the bulk is reduced, and since the water activity has decreased due to drying, even if it is put in the food waste container 2 as it is, it will rot. It does not cause mold or mold. Therefore, until the raw garbage storage container 2 is full, the raw garbage can be put on the dried raw garbage one by one and dried. Then, the dried food waste remaining in the food waste container 2 and the condensed water accumulated in the condensed water container 20 are periodically collected and discarded.

In this embodiment, the food waste container 2 is tilted and rotated in order to increase the effect of mixing food waste, but since the stirring action can be obtained only by the rotary blade 5, the food waste is stored. The container 2 may be vertically fixed.

The second embodiment in which the food waste container is fixed vertically will be described below. This embodiment will be described with reference to FIGS. In FIG. 4, 31 is a heat insulation container, which forms an air layer as a heat insulation layer between the double walls. 32
Is a food waste container installed in the heat insulating container 31. A fixed blade 33 is provided on the inner wall of the garbage storage container 32. Reference numeral 34 designates blades arranged in upper and lower stages, and the tips of the respective blades are rotary blades which rotate while intersecting one side 34a substantially horizontally with the fixed blade 33 and the other side 34b substantially perpendicularly intersecting the fixed blade 33. The rotation of the motor 35 is transmitted to the attached rotary shaft 35a via a belt 36. The fixed blade 33 and the rotary blade 34 constitute a crushing stirring means for crushing and stirring the food waste inside the food waste container 32.

Reference numeral 38 designates a condensing part arranged on the outer peripheral part of the heat insulating container 31, and a cooling fan 39 is installed outside thereof.
Reference numeral 40 denotes a condensed water collecting container for collecting and collecting condensed water flowing out from the condenser 38. 41 is a lid that is openably and closably attached to the upper part of the main body of the garbage processing machine.
It is sealed at. Reference numeral 42 denotes a stirring fan that is a centrifugal fan that stirs the air in the food waste container 32, and has a rotation surface that is provided substantially parallel to the lower surface 47 of the lid 41 and projects into an upper opening of the food waste container 42. Reference numeral 43 denotes a heater which uses the air stirred by the stirring fan 42 as hot air, and is arranged on the outer periphery of the stirring fan 42. And the stirring fan 42
The heater 43 constitutes a drying means for drying the food waste. In addition, the heat insulation container 31 and the garbage storage container 32
And the lower surface 47 of the lid 41 are arranged with a gap.

Reference numeral 44 denotes a hood provided on the lower surface 47 of the lid 41 so as to guide the hot air discharged from the stirring fan 42 into the food waste container 32. 45 is a stirring fan 42
Is installed in the lid 41 together with the cover 46 and the heat insulating material 60. Shaft 49 of drive motor 45
As shown in FIG. 7, while penetrating the lower surface 47 of the lid 41 and covering the penetrating portion 48, a bearing 57 having a grease reservoir 57a is slidably provided. The bearing 57 is biased by the spring 58 toward the lower surface 47 side of the lid 41. A self cooling fan 59 is provided on the shaft 49.

Further, as shown in FIG. 4, the condensing part 38 and the condensed water collecting container 40 are connected by a hose 50.
0 is branched and connected to the deodorizing device 21. Further, in the condensed water collecting container 40, there is provided a detection device 53 composed of a float switch for detecting that the condensed water is full. In the present embodiment, a float 55 having a magnet 54 built therein and a reed switch 56 are provided. Are configured. Further, the condensed water collecting container 40 is arranged in the vicinity of the deodorizing device 51, which is relatively hot when energized, so that the heat acts on the detecting device 53. Further, a temperature sensor 52 is provided in the vicinity of the heater 43 and in the passage of the exhaust air from the stirring fan 42 to control the temperature of the heater 43.

The operation of the garbage processing machine configured as described above will be described. The raw garbage put in the raw garbage storage container 32 is stirred by the rotary blade 34 and crushed by the rotary blade 34 and the fixed blade 33. Stirring fan 42
The hot air from the heater 43 circulates in the space formed by the lower surface 47 of the lid 41, the hood 44, and the food waste container 32, and heats the food waste while stirring the air in the space. Water vapor is generated from the heated garbage and overflows into the condensing section 38 through a gap between the upper end of the garbage container 32 and the lower surface 47 of the lid 41. Due to the function of the heat insulating container 31, the temperature of the condenser 38 is lower than that of the inside of the food waste container 32,
The water vapor is condensed into water and collected in the condensed water collecting container 40. On the other hand, the water vapor containing the odorous component that has not been completely condensed is guided from the branch hose to the deodorizing device 51, where the odorous component is purified and discharged to the outside. The crushed and dried food waste remains in the food waste container 32, but the bulk is reduced, and since the water activity is decreased due to drying, the food waste will rot or mold even if it is put in as it is. There is no.

Here, when the condensed water collecting container 40 is full, the detection device 53 operates, and the next operation is controlled so that the condensed water cannot be operated unless the condensed water is discarded. Since the capacity of the condensed water collecting container 40 has a margin for one treatment of the condensed water, at the time when the detection device 53 operates, even if the detection device 53 operates during operation, that time is processed to the end. However, in the next operation, the condensed water cannot be operated unless the condensed water is discarded, and the condensed water collecting container 40 is prevented from overflowing with water. If the outside air temperature drops and the condensed water freezes and the detector 53 does not move, the water may overflow. However, the deodorizer 5 that is a heat source near the detector 53
Since No. 1 is provided, the frozen water of the condensed water is released by the heat of the deodorization device 51 during operation, and the detection device 53 does not normally work and the water does not overflow.

Next, the operation of the stirring fan 42 will be described with reference to FIG. The air discharged from the stirring fan 42 has a flow velocity V of the rotational direction component of the stirring fan 42 as shown in FIG. 5, and is guided into the raw garbage storage container 32 while being guided by the hood 44, and the raw garbage is discharged. Is heated and then sucked into the stirring fan 42 again from the central portion of the stirring fan 42. Therefore, since the hot air rotates around the heater 43 at a high speed, the temperature sensor 52 provided near the heater 43 is affected by the steam rather than the radiant heat of the heater 43 when the hot air contains steam during the drying process. That is, the temperature inside the food waste container 32 is measured. Therefore, the heater 43 is frequently used to keep the inside of the food waste container 32 at the drying temperature.
Can be input to speed up drying.

When the drying progresses and the amount of steam in the hot air decreases, the temperature sensor 52 is easily affected by the radiant heat of the heater 43, and the temperature of the heater 43 itself is measured. Therefore, when the amount of steam decreases and the temperature of the heater 43 rises rapidly, the temperature sensor 52 causes the heater 4 to
Since the temperature of 3 itself is measured, the overheat of the heater 43 can be prevented and the power consumption of the heater can be saved.

Next, the crushing and stirring of the garbage will be described with reference to FIG. The rotary blade 34 is formed by two blades arranged in upper and lower two stages, and the tip of one blade 34a is shown in FIG.
As shown in (a), it intersects the fixed blade 33 substantially horizontally, and the tip of the other blade 34b has a fixed blade 33 as shown in FIG. 6 (b).
And intersects almost vertically. Therefore, the garbage can be efficiently crushed due to the different intersecting angles, and when the intersecting angle is in one direction, the fixed blades 33 are easily entangled with the garbage, but by changing the intersecting angle, the entanglement can be prevented. Can be prevented. Moreover, since the rotary blades are arranged in the upper and lower two stages, the food waste moves not only in the rotation direction but also in the vertical direction, so that the stirring is efficiently performed and the drying of the food waste is promoted. Further, since the mixing performance of the raw garbage is enhanced, the raw garbage can be effectively stirred without tilting the raw garbage container.

Next, the relationship among the stirring means 42, the drive motor 45, and the lid 41 will be described with reference to FIG. The bearing 57 slidably provided on the shaft 49 of the drive motor 45 is provided with the grease reservoir 57a and covers the gap between the shaft 49 of the drive motor 45 and the penetrating portion 48 to seal the shaft 49 and the penetrating portion 48. The gap can be set with a margin, so that it is possible to cope with the variation in the gap due to vibration and thermal expansion. The bearing 57 and the spring 58 are air-cooled by the self-cooling fan 59, so that the stirring fan 4
The heat transferred from the drive motor 45 to the drive motor 45 is radiated to reduce the temperature rise of the drive motor 45.

[0052]

As described above, according to the first means of the present invention, the food waste put in the food waste container is heated and dried by the food waste heating means while being crushed and agitated, and The generated water vapor containing the odorous component is condensed in the condensing section and accumulated in the condensed water container. On the other hand, the water vapor containing the odorous components that cannot be completely condensed is guided to the deodorizing device and the odorous components are purified. The crushed and dried food waste remains in the food waste storage container, but the bulk is reduced, and since the water activity has decreased due to drying, it will rot even if put directly in the food waste storage container. No mold will be generated. Therefore,
The garbage can be placed on top of the dried garbage and dried until the garbage container is full. Moreover,
Since the garbage is crushed, heat can be easily transferred to the inside of the garbage and the drying speed can be increased to shorten the drying treatment time.

According to the second means of the present invention, a fixed blade provided on the inner wall of the food waste container and a rotary blade provided on the inner bottom of the food waste container are used as the crushing and stirring means, and the fixed blade and the rotary blade are rotated. It grinds food waste between blades, and can grind, stir and dry food waste efficiently.

According to the third means of the present invention, since the fixed blade and the rotary blade have different intersecting angles, it is possible to efficiently grind food waste and, when the intersecting angle is one direction, Garbage is easily entangled with the fixed blade, but entanglement can be prevented by changing the crossing angle. Moreover, since the blades are arranged in the upper and lower stages, the food waste moves not only in the rotating direction but also in the vertical direction, so that the stirring is efficiently performed and the drying of the food waste is promoted.

According to the fourth means of the present invention, at least the rotary blade is intermittently rotated by repeatedly stopping and rotating, and is controlled so that the rotation direction is reversed every time the rotary blade is rotated, so that the rotary blade is locked. It is possible to crush and stir food waste more effectively.

According to the fifth means of the present invention, by providing a crushing blade for crushing the garbage storing bag in a part of the rotary blade, when the garbage is put into the garbage storing container, Since it can be done while it is put in the bag for storing garbage, it is easy to handle the garbage.

According to the sixth means of the present invention, the rotary blade and its rotary shaft are detachably engaged with each other.
The garbage container and rotary blade can be easily cleaned.

According to the seventh and eighth means of the present invention, the fixed blade and the rotary blade are made of metal, and the surface is covered with plastics while leaving the blade portion at the tip, or the rotary blade itself is made of plastics. With the configuration, the raw garbage is less likely to be burned on the rotary blade, and the post-treatment is facilitated.

According to the ninth and tenth means of the present invention, the water vapor generated from the food waste container is condensed in the condensing part and accumulated in the condensed water collecting container. Therefore, the accumulated condensed water should be periodically discarded. Then, there is no need to perform post-processing each time. In addition, the amount of water in the condensate collection container can be detected by the detector, and the detector is equipped with a deodorizing device that is a heat source in the vicinity, so the condensation water freezes during operation due to the heat of the deodorizing device. Even if the outside temperature changes, the detection device operates normally so that the condensed water collecting container can be prevented from overflowing with water.

According to the eleventh and twelfth means of the present invention, since hot air is circulated in the entire garbage storage container by the stirring fan provided on the lid above the garbage storage container, the garbage is uniformly distributed. It can be dried, and it is possible to prevent the drying of the undried food waste. Also, since the bearing provided on the shaft of the drive motor covers and seals the gap between the shaft and the penetrating portion, the gap between the shaft and the penetrating portion can be set with a margin, so that the gap due to vibration and thermal expansion can be set. It is possible to cope with fluctuations in the temperature and there is no steam leakage. Furthermore, since the bearing is air-cooled by the self-cooling fan, the heat transmitted from the stirring fan to the drive motor can be radiated, and the temperature rise of the drive motor can be reduced.
