At this time, the air blown into the inner pot 3 as the blower fan 40 is driven collides with the garbage in the inner pot 3 and reverses, then rises and is sucked into the suction port 60. It is sprayed with raw garbage again. The vapor generated from the garbage flows out to the exhaust port 35a along with the rising air flow.

3 and 6, in the space 29 between the outer lid 26 and the inner lid 27, the catalytic converter 4 which catalyzes the vapor discharged from the exhaust port 35 to oxidize and deodorize.
Install 9. In this catalytic converter 49, a catalyst body 50 in which a precious metal-based catalyst is carried on a carrier such as ceramic is filled in a catalyst cylinder 51, and a heater 52 is provided at the center of the catalyst body 50.
It is configured by penetrating. The heater 52 maintains the catalyst temperature at about 500 ° C. in order to activate the catalyst when drying the garbage. In FIG. 4, the steam inlet 53 provided in the catalyst cylinder 51 and the left and right exhaust ports 35 are connected by a bifurcated exhaust pipe 54, but the temperature of the steam discharged from the exhaust port 35 before entering the catalytic converter 49. The vapor inlet 53 of the catalyst tube 51 should be placed as close as possible to the exhaust port 35 so as not to lower or cause dew condensation, and the distance between both ports 53, 35 should be set short, so that the exhaust pipe 54 as short as possible is sufficient. There is. Further, the catalytic converter 49 is heavy, so that the lid 2 is not difficult to open and close because of this.
This catalytic converter 49 is arranged as close as possible to the hinge 30 on the lid 2.

In FIGS. 4 and 6, the exhaust port 55 provided on the opposite side of the catalyst cylinder 51 of the catalytic converter 49 from the vapor inlet 53 faces the external exhaust port 56 provided on the rear side of the lid 2. On the outside of the external exhaust port 56, a guard 57 made of a heat insulating material is attached to cover the upper side and the lateral side of the external exhaust port 56 for safety and prevention of dust intrusion.

As shown in FIG. 6, the exhaust port 55 and the external exhaust port 56 of the catalyst cylinder 51 of the catalytic converter 49 are positioned in the upper space 46 in which the cooling fan 44 exists. Therefore, the cooling fan 44 has not only the function of reducing the surface temperature of the outer lid 26 but also the exhaust port 5 of the catalytic converter 49.
It also exerts a forced discharge function of promptly discharging the steam discharged from 5 toward the external exhaust port 56.

In FIGS. 3 and 6, the catalytic converter 49 radiates heat from the surface of the catalyst cylinder 51, and this heat radiation preheats the outside air sent by the pump unit 36 before entering the air supply port 34. Use as a source. Therefore, the outer side of the catalyst cylinder 51 is covered with a heat insulating cylinder 61 formed in a bulging shape in the middle of the second air supply pipe 39, so that both cylinders
A preheating chamber 62 is formed between the two. Insulation cylinder 61 is air inlet 6
3 and an outlet 64, the air inlet 63 is connected to the end 37a of the first air supply pipe 37, and the outlet 64 communicates with the air supply port 34 by the second air supply pipe 39. The lid 2 can be opened and closed around the hinge 30 as described above, and when the lid 2 is closed for this reason, as shown in FIG.
3 is abutted with the end 37a of the first air supply pipe 37 so as to communicate therewith. A check valve 65 is inserted inside the end 37 a of the first air supply pipe 37. By covering the outside of the catalytic converter 49 with the heat insulating cylinder 61, it is possible to reduce the heat radiation loss from the surface of the catalyst cylinder 51 and improve the heating efficiency of the catalyst.

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 drive motor 21 starts to rotate, the stirring blade 9 stirs the garbage, and the heater 5 generates heat. The temperature of the inner pot 3 rises due to the heat generated by the heater 5, and the water content of the garbage starts to evaporate. The evaporated water, along with the odor, passes through the exhaust pipe 54, the exhaust pipe 54, the catalytic converter 49, is deodorized, and is discharged to the external exhaust port 56. At this time, since there is an increase in the internal pressure of the inner pot 3, the pump unit 36 drives the air to be automatically exhausted without sending air into the inner pot 3. However, in order to further increase the exhaust efficiency, the pump unit It is preferable to drive 36 to send the outside air. Further, since the odor in the inner pot 3 is thinned by sending in the outside air, the load on the catalytic converter 49 can be reduced accordingly.

When the evaporation proceeds to some extent and the internal pressure of the inner pot 3 decreases, the air containing a large amount of water remains in it. At this time, the pump portion 36 is driven to discharge the outside air. It is sent from 34 to promote exhaust. In addition, the outside air that has been sent is preheated by the heat radiation of the catalytic converter 49 and forcedly blown on the garbage by the blower fan 40, so that the drying is promoted. In particular, it is said that the blower fan 40 drives warm air to blow on the garbage in the inner pot 3, and the warm air that hits the garbage and rises and reverses is sucked into the suction port 60 and blown again to the garbage by the blower fan 40. A strong circulating flow occurs. Therefore, the steam generated during the drying of the food waste is promptly discharged from the exhaust port 35 together with the rising airflow of the warm air.

When the heater 5 is operated for a predetermined time, the heating of the inside of the inner pot 3 by the heater 5 is stopped and the drying process of the garbage is completed. The user opens the lid 2, removes the inner pot 3 from the outer pot 4, and disposes of the treated dry dust.

(Other Embodiments) As means for taking in the outside air into the inner pot 3, in addition to the combined use of the pump portion 36 and the blower fan 40 as in the above embodiment, only the blower fan 40 may be used. When the pump unit 36 and the blower fan 40 are used together, even if the blower fan 40 does not have a high capacity to withstand the peak internal pressure of the inner pot 3 and a capacity lower than that, Since the shortage of the outside air intake at the time when the internal pressure of the inner pot 3 reaches the peak can be compensated by the outside air intake of the pump unit 36, the amount of the outside air intake to the inner pot 3 can be quantified and the outside air intake capacity can be improved. When only the blower fan 40 is adopted, the amount of air sucked into the inner pot 3 can be quantified by using the blower fan 40 and the quantitative control valve having a high capacity to withstand the peak internal pressure of the inner pot 3. That is, when the internal pressure of the inner pot 3 is low, the air intake amount increases excessively and is wasted. The problem of the variation of the air intake amount is that the control valve for quantitatively adjusting the air intake amount according to the variation of the internal pressure of the inner pot 3 Can be solved by using.

As the blower fan 40, a sirocco fan as shown in FIG. 9 can be adopted instead of the axial fan. In this embodiment, the outside air taken in from the air supply port 34 by the blower fan 40 is blown into the inner pot 3 from the outlet 66 provided outside the center of the lower surface of the fan cover 47, hits the garbage, and rises upside down. The ascending airflow is sucked into the suction port 60 provided at the center of the lower surface of the fan cover 47 and is blown again to the garbage by the blower fan 40. The steam generated during the drying of the food waste goes up together with the ascending airflow, and is discharged from the exhaust port 35 provided in parallel with the outlet 66. In this case, the exhaust port 35 may be provided in the vicinity of the central suction port 60 instead of being provided side by side with the outlet 66. In such a case, the vapor generated during the drying of the garbage can be discharged more quickly from the exhaust port 35 together with the ascending airflow sucked into the suction port 60.

The air supply port 34 is not necessarily provided in the lid 2, and may be provided not only in the lid 2 but also in the upper portion of the peripheral wall of the inner pot 3 so as to be located above the inner pot 3. Good. As a heating means for the inner pot 3, the inner pot 3 may be provided with a magnetron for heating raw garbage by high frequency.

[0027]

As described above, according to the first and second aspects of the present invention, the air supply port 34 is provided so as to be located above the inner pot 3, and the air supply port 34 is provided on the outlet side thereof. Blower fan 4
Since 0 is arranged, the outside air can be effectively sent from above the inner pot 3 to all the inside thereof. Moreover, since the outlet side of the air supply port 34 and the suction side of the blower fan 40 are communicated with each other, a forced circulation flow of the outside air can be generated in the inner pot 3 and the drying of the garbage can be promoted. . Further, the steam and odor generated during drying can be forcibly and promptly discharged to the exhaust port 35 without being stagnant in the inner pot 3, so that the peaks of steam and odor can be constantly suppressed to a low level, and the exhaust port Even when a deodorizing device such as a catalyst is provided on the downstream side of 35, the size can be reduced.

According to the third aspect of the present invention, since the blower fan 40 and the pump portion 36 are used together to take in the outside air into the inner pot 3, even when the blower fan 40 causes a shortage of outside air, this shortage is taken up by the pump portion. This can be supplemented by the external air intake of 36, and the intake amount of the external air can be quantified and the external air intake capacity can be improved.
