A heater 5 such as a sheathed heater is installed as a heating means on the inner bottom surface of the outer pot 4. This heater 5
The temperature of the air in the space 8 formed between the inner kettle 3 and the outer kettle 4 rises due to the heat generation, and the heat causes the inner kettle 3 to be heated to the extent that it does not burn the garbage (about 110 ° C. or less). .

The peripheral side and bottom of the outer pot 4 are covered with a heat insulating container 7 containing a heat insulating material 6 to reduce heat radiation to the outside. The outside of the heat insulating container 7 is covered with the outer box 1.

At the center of the inner bottom of the inner pot 3, a stirring blade 9 for stirring the raw garbage and promoting the drying is attached. The stirring blade 9 rotatably supports a stirring shaft 11 through a bearing 12 in a bearing cylinder 10 which is vertically supported and fixed to the center of the inner bottom of the inner pot 3, and a blade plate holding cylinder 13 is mounted on the stirring shaft 11. Is fixed.

A clutch piece 14 is fixed to the lower end of the stirring shaft 11. On the other hand, at the center of the support base 15 that supports and fixes the bottom of the heat insulating container 7, a driving shaft 16 is supported immediately below the stirring shaft 11 via a bearing 17 so as to be on the same axis as the driving shaft 16.
A clutch piece 19 that engages and disengages with the clutch piece 14 when the inner hook 3 is moved in and out of the outer hook 4 is fixed to the upper end of the drive shaft 16. The drive motor 2 installed on the lower end of the drive shaft 16 and the insole plate 20 stretched over the lower part of the outer box 1.
Pulleys 23 and 24 are fixed to the shaft 22 of No. 1 and a belt 25 is hung between the pulleys 23 and 24. At this time, when the drive motor 21 is driven, the stirring shaft 1 is passed through the belt 25, the driving shaft 16, and the clutch pieces 19 and 14.
1 rotates.

The lid 2 is doubled with an outer lid 26 having a size corresponding to the outer shape of the outer box 1 and an inner lid 27 for sealing the upper part of the inner pot 3, and a space is provided between the inner and outer lids 27, 26. 29 are formed. The lid 2 of this double structure is attached at its rear end to the upper rear end of the outer box 1 with a pair of left and right hinges 30,
It can be opened and closed vertically around the hinge 30.

A fan casing 31 is formed on the lid 2. In this fan casing 31, a part of the lower surface of the inner lid 27 corresponding to the upper side of the inner pot 3 is made into an upper wall 31a, and the upper wall 3a
1a and a lower wall 34 which is superposed on a part of the lower surface of the lower wall 34 with a packing 32 made of silicon rubber or the like and fixed with screws 33 or the like. An intake port 35 is opened in the center of the upper wall 31a.
A suction port 36 is opened in the center of the above, and a blow port 37 and an internal exhaust port 39 are opened in the outer peripheral portion of the suction port 36 of the lower wall 34.

A fan drive motor 41 such as a bear removal coil induction motor, which projects a shaft 40 at both upper and lower ends, is mounted and fixed on the upper part of the fan casing 31, and the shaft 4 on the lower end side thereof is fixed.
0 is inserted into the fan casing 31 through the intake port 35. Inside the fan casing 31, on the shaft 40 on the lower end side of the fan drive motor 41, an intake fan 42 and a circulation fan 4 which are centrifugal turbofans.
3 and 3 are arranged vertically and fixed.

In the illustrated example, the centrifugal intake fan 42 and the circulation fan 43 are, as shown in FIGS. 3 and 4,
Curved or linear rearward vanes 45 and 46 are radially mounted in the same arrangement on the upper and lower surfaces of a flat disc 44 having a boss 44a passing through the shaft 40 in the center. The rearward-facing blades 45 on the upper surface side allow the outside air to enter the intake port 35.
An intake fan that sucks into the fan casing 31 is configured. The rearward-facing blades 46 on the lower surface side blow the outside air sucked by the rearward-facing blades 45 on the upper surface side into the inner pot 3 through the blow-in port 37, suck the air flow that rises upside down by hitting the raw garbage from the suction port 36, and regenerates it again. Configure a circulation fan that blows dust along with the outside air.

That is, the intake fan 42 and the circulation fan 4
3 and 3 are integrated. By adopting this integral structure, the assembling work can be simplified, but instead of this, a centrifugal intake fan 42 and a circulation intake fan 42 in which rear facing blades are respectively attached to separate disks are used. The fan 43 and the fan 43 may be arranged vertically on the same shaft 40.

On the shaft 40 on the upper end side of the fan drive motor 41, a cooling fan 47 which is also a centrifugal turbo fan is provided.
Is stuck. As shown in FIG. 2, an eddy-shaped fan-surrounding rib 49 is provided on the inner surface of the outer lid 26 to form a spiral-shaped air duct 50 so that the discharge side end 50a faces the external exhaust port 51. The cooling fan 47 is housed in the winding air passage 50.

When the cooling fan 47 rotates, the outside air drawn into the lid 2 through the outside air intake port (not shown) is sucked in from below, and the outside air is guided along the fan surrounding rib 49 on the inner surface of the outer lid 26. Left and right hinges 30 on the rear side of the lid 2
It discharges toward the external exhaust port 51 provided between 30 and mixes with the exhaust gas discharged from the external exhaust port 51, and cools the exhaust gas.

Below the inside of the outer box 1, a pump section 5 including an air pump or the like for pumping the outside air to the intake port 35.
2 are installed. The pump unit 52 and the intake port 35 are connected by an air supply pipe 53. In order to further enhance the catalytic deodorizing effect at the time of exhaust, which will be described later, the pump unit 52 may be provided with an ozone generator so as to send air containing ozone to the intake port 35.

In the space 29 between the outer lid 26 and the inner lid 27, there is provided a catalyst deodorizing section 54 which catalyzes the vapor discharged from the internal exhaust port 39 to oxidize and deodorize. The catalyst deodorizing section 54 is configured by filling a catalyst cylinder 55 with a catalyst body 55 in which a precious metal-based catalyst is supported on a carrier such as ceramics, and passing a heater 57 through the center of the catalyst body 56. The heater 57 maintains the catalyst temperature at about 500 ° C. in order to activate the catalyst when drying the garbage.

Further, the catalyst deodorizing portion 54 is heavy, so that the catalyst deodorizing portion 54 is located near the hinge 30 on the lid 2 so that the lid 2 is not easily opened and closed around the hinge 30. Place as close as possible.

In FIG. 2, an inflow port 58 provided in the catalyst cylinder 56 and an internal exhaust port 39 are connected by an exhaust pipe 59. In this case, the steam inlet 58 of the catalyst cylinder 56 is arranged as close as possible to the internal exhaust port 39 so that the temperature of the steam discharged from the internal exhaust port 39 does not drop before entering the catalyst deodorizing section 54 and dew condensation occurs. The distance between the two ports 56 and 39 is set to be short so that the shortest possible exhaust pipe 59 is sufficient.

Further, when the dew condensation water instantaneously condenses when the lid is opened and this dew condensation water flows into the catalyst deodorizing portion 54, the catalytic function is deteriorated. Therefore, as a countermeasure against this, an exhaust pipe 59 formed in a U shape is used. . According to this, even if the lid 2 is pivoted upward about the hinge 30 and opened, the dew condensation water of the vapor temporarily collects in the U-shaped portion 59a of the U-shaped exhaust pipe 59, so the catalyst deodorizing portion 54 Can be prevented from flowing directly into the.

Inflow port 58 of catalyst cylinder 56 of catalyst deodorizing section 54
The outlet 60 provided on the side opposite to the side is exposed to the external exhaust port 51 provided between the hinges 30 on the rear side of the lid 2. The exhaust gas discharged from the outlet 60 of the catalyst cylinder 56 is 30
Although the temperature is close to 0 ° C., it is effectively cooled by the outside air discharged from the cooling fan 47. Therefore, a person near the apparatus may be burned by the exhaust air from the external exhaust port 51,
There is no risk of thermal deformation of the external exhaust port 51 and its peripheral portion.

The catalyst deodorizing portion 54 radiates heat from the surface of the catalyst cylinder 56, and this heat radiation is used as a preheating source for preheating the outside air fed by the pump portion 52 before entering the intake port 35. Therefore, as shown in FIG. 2, the outside of the catalyst cylinder 56 is covered with a heat insulating cylinder 62 formed in a bulge shape in the middle of the air supply pipe 53 so that the preheating chamber 6 is provided between the cylinders 56 and 62.
3 is formed.

Further, by covering the outside of the catalyst deodorizing portion 54 with the heat insulating cylinder 62 as described above, it is possible to reduce the heat radiation loss from the surface of the catalyst cylinder 56 and improve the heating efficiency of the catalyst. Is.

Next, the operation of the apparatus having the above configuration will be described. When the lid 2 is opened and garbage is put into the inner pot 3 and a drive switch (not shown) is turned on, the heater 57 of the catalyst deodorizing section 54 generates heat and the catalyst temperature rises. Simultaneously with or slightly after that, the heater 5 of the inner pot 3 generates heat, after which the drive motor 21 starts to rotate, and the stirring blade 9 stirs the garbage.

Due to the heat generated by the heater 5, the temperature in the inner pot 3 rises, and the water content of the garbage starts to evaporate. The evaporated water, along with the odor, passes through the exhaust pipe 59 from the internal exhaust port 39, passes through the catalyst deodorizing section 54, is deodorized, and is discharged to the external exhaust port 51. In this case, the exhaust gas can be effectively cooled by the outside air discharged by the cooling fan 47.

At the start of stirring, there is a rise in the internal pressure of the inner pot 3, so the pump 52 and the intake fan 42 are dared to do so.
Exhaust is performed naturally without driving the outside air into the inner pot 3. However, in order to further increase the exhaust efficiency, the pump unit 52 and the intake fan 42 are driven to bring the outside air into the inner pot 3. It is better to force it to be sent. In that case, the pump unit 52 operates continuously or intermittently.

In this case, since the centrifugal intake fan 42 applies a pressure to the outside air by the action of the centrifugal force generated by the rotation of the rearward blades 45 and sends it into the outside air, the steam with odor or dust generated in the inner pot 3 It is possible to prevent backflow due to the internal pressure of the shuttle 3. Therefore, when the pump unit 52 is in the intermittent operation, it is possible to prevent the odor from flowing back to the pump unit 52 and being discharged to the outside when the operation is stopped.

It is also possible to prevent the lower end side shaft 40 of the fan drive motor 41 exposed in the fan casing 31 from being worn or rusted due to the dust adhering to the backflow steam. Further, since the odor in the inner pot 3 is thinned by sending in the outside air, the load on the catalyst deodorizing section 54 can be reduced accordingly.

As the evaporation proceeds to some extent and the internal pressure of the inner pot 3 decreases, air containing a large amount of water remains and remains. At this time, therefore, the intake fan 42 and the circulation fan 4
3 and the pump unit 52 are driven to blow the outside air into the inner pot 3 through the blow-in port 37 to promote the exhaust.

The operation of the intake fan 42 is as described above. When the circulation fan 43 is driven, the outside air taken in by the intake fan 42 is blown to the raw garbage in the inner pot 3, hits the raw dust, and reversely rises, and this rising airflow is sucked into the suction port 36 by the circulation fan 43. Then, a strong circulating flow occurs in which the dust is sprayed again onto the garbage. Therefore, the drying of the garbage is promoted, and the steam generated during the drying is promptly discharged from the internal exhaust port 39 together with the ascending airflow. If the outside air sent in is preheated by utilizing the heat radiation of the catalyst deodorizing section 54, the circulation fan 43 is forced to blow it on the garbage, so that the drying is further promoted.

At the same time, the cooling fan 47 is also driven, and this cooling fan 47 sucks the outside air entering from the outside air intake port (not shown) into the lid 2 from below, and the outside air is swirled into the spiral-shaped air duct 5.
The exhaust gas is discharged toward the external exhaust port 51 along 0, and is mixed with the exhaust gas discharged from the external exhaust port 51 to cool the exhaust gas.
The cooling fan 47 can also cool the fan drive motor 41 itself, and can also reduce the rise in the surface temperature of the outer lid 26.

When the heater 5 is operated for a predetermined time, the heating of the inner pot 3 by the heater 5 is stopped, and at the same time or after that, the drive switch is turned off to complete the drying process of the garbage. The user opens the lid 2, removes the inner pot 3 from the outer pot 4, and disposes of the treated dry dust.

(Second Embodiment) FIGS. 5 to 7 show a second embodiment of the present invention.

The opening 69 is opened in a state of communicating with the spiral wind passage 50, and the fan drive motor 4 is inserted into the suction opening 69.
A cooling fan 47 mounted on the shaft 40 on the upper end side of No. 1 is arranged. The other structure is similar to that of the first embodiment.

At this time, when the cooling fan 47 is driven, fresh and dry outside air is introduced into the outside air intake port 66 and the conduction port 6.
7 is sucked into the fan casing 65, and the sucked outside air passes through the blades of the cooling fan 47 and is discharged to the spiral wound air passage 50 toward the external exhaust port 51, and is discharged from the external exhaust port 51. Cool the exhaust gas by mixing with the exhaust gas. Further, the fan drive motor 41 can be cooled by the outside air sucked into the fan casing 65,
The outer lid 26 is formed by the airflow flowing in the spiral wound air passage 50.
An adiabatic effect of reducing the rise in the surface temperature of the is also obtained.

In this case, since the fan casing 65 is provided, the outside air suction port 6 is driven by the driving of the cooling fan 47.
6, inside the fan casing 65, and the spiral-shaped air duct 5
Since the airflow P flowing through the 0 route is positively promoted, the cooling effect of the exhaust gas and the fan drive motor 41 is improved, and the heat insulating effect of the outer lid 26 by the airflow can be improved.

Incidentally, in this embodiment, as shown in FIG. 6, the intake air shielding plate 49a is provided at the edge of the spiral fan-surrounding rib 49 which faces the external exhaust port 51, so that the external air is sucked in from the external exhaust port 51. It is designed so that it will not be opened, that is, it will not be a shortcut.

(Other Embodiments) As a means for taking in the outside air into the inner pot 3, in addition to using the pump portion 52 and the intake fan 42 as in the above embodiment, the pump portion 52 is omitted and the intake fan is omitted. Only 42 may be used.

In the above embodiment, the preheating chamber 63 is connected to the catalyst deodorizing section 5.
Although it is formed on the outer circumference of No. 4, instead of this, it may be formed in the middle of the other exhaust path. Further, as the heating means 5 for the inner pot 3, the inner pot 3 is equipped with a magnetron for heating the garbage by high frequency, and the inner pot 3 by electromagnetic waves.
May be directly self-heated by iron loss heat generation, or the outer pot 4 may be heated to indirectly heat the inner pot 3.

In the above embodiment, the inner pot 3 and the outer pot 4 are provided separately, but instead of this, the inner pot 3 and the outer pot 4 may be integrated into one unit. Pot 3 or inner pot 3
The one kettle that integrally configures the outer kettle 4 and the outer kettle 4 may be of a retractable type or a fixed type.

Instead of the centrifugal intake fan 42 and the circulation fan 43, it is possible to blow the outside air into the inner pot 3 with one axial-flow fan. The exhaust path is provided between the inner pot 3 and the outer box 1 instead of being provided inside the lid 2,
