When the heater 19 of the deodorizing device 18 is energized and the dilution fan 24 is energized, the exhaust gas from the processing tank 1 flows to the first exhaust passage 15 where the deodorizing device 18 is provided.

When the heater 19 of the deodorizing device 18 is energized, the exhaust gas discharged to the first exhaust passage 15 as described above is heated to a catalyst reaction temperature of 250 to 300 ° C. and supplied to the catalyst 20. . The high-temperature exhaust gas supplied into the catalyst 20 heats the catalyst 20 to the same temperature, is deodorized by the oxidative decomposition reaction of the malodor promoted by the catalytic action, and substantially passes through the catalyst 20 while passing through the catalyst 20.

Further, in addition to the first exhaust passage 15,
A second exhaust passage 16 for directly discharging the exhaust gas from the processing tank 1 to the outside is provided, and can be switched by a simple switching valve 17 by an operation knob 17b. By directly discharging the exhaust gas from the passage 16 to the outside, pressure loss is reduced, smooth exhaust is possible, and water vaporized from garbage can be quickly discharged.

Also, compared to the conventional exhaust gas in which the exhaust gas always passes through the exhaust passage having the deodorizing device irrespective of whether or not the deodorizing process is performed, dew condensation in the cold deodorizing device with the heater turned off,
It is possible to prevent the exhaust gas mixed with the fine powder that is dried and scattered from passing through the catalyst 20 unnecessarily, thereby preventing the clogging or the like, and extending the life of the deodorizing device 18.

FIG. 6 is a cross-sectional view of a main part on the rear side of an organic matter treating apparatus according to a second embodiment of the present invention, FIG. 7 is a cross-sectional view of a main part on the upper side when there is no deodorization, and FIG. 9 is an enlarged perspective view of the switching valve, and FIG. 10 is a central section viewed from the side. The same reference numerals as those in the above-described embodiment indicate the same or corresponding parts.

In the present embodiment, the switching valve 17 is connected to the motor 40
It is driven by. That is, as shown in FIG. 9, the switching valve 17 is configured such that the rotating shaft 41 of the motor 40 is connected to a fan-shaped central portion formed on the lower side thereof and is driven.

In this embodiment, an odor sensor 43 is provided downstream of the exhaust hole 13. The output of the odor sensor 43 is input to a control unit such as a macro computer (not shown), and the control unit controls the motor 40 to switch the switching valve 17.

That is, when the odor of the exhaust gas exceeds a preset level, the odor sensor 43 detects the odor and the switching valve 17 is rotated by the motor 40 to the position shown in FIG. First exhaust passage 15 with 18
And deodorize. When the odor level falls below the set level, the switching valve 17 rotates to the position shown in FIG. 7, and the exhaust gas is directly discharged from the second exhaust passage 16 to the outside.

Thus, in addition to the functions and effects of the above-described embodiment, switching between deodorizing operation and deodorizing operation can be automatically performed, and unnecessary deodorizing operation or the like is not performed without the user noticing. Efficient operation of garbage disposal can be performed.

A hole 30a and an intake hole 31a are formed.

The partition plate 45 partitions the space between the intake port 44 and the ventilation holes 26 and 27 and, as shown in FIG. 6, connects the space between the deodorizing device 18 and the speed reduction mechanism 11 to the deodorizing device 1.
8, and extends laterally above the deceleration mechanism 19 from the upper side of the deodorizing device 18 to the position communicating with the ventilation hole 30a on the opposite side.

With this configuration, all the outside air from the intake port 29 formed on the bottom surface side of the outer case 2 is
All of the outside air sucked from the ventilation holes 26 and 27 formed between the deodorizing device 18 and the dilution fan 24 and used for dilution and from the air inlet 44 formed on the back side of the outer case 2 is supplied to the deodorizing device 18. Since it is used for suctioning into the processing tank 1 through the suction path 32 formed along, the heating of the intake air into the processing tank 1 and the dilution of the exhaust gas from the deodorizing device 18 are efficiently performed independently. Can be.

Further, ventilation holes 30,
The presence of the air inlet 30a and the air inlet holes 31 and 31a allows the external air sucked in as described above to quickly spread throughout the processing tank 1.

Even with this configuration, the switching operation of the switching valve 17 can be reliably performed as in the case of the knob operation of the first embodiment, and the deodorizing on / off operation can be performed in comparison with the knob operation. The operability is improved because it can be realized by a simple operation of a button or the like.

In this case, the motor 40 is controlled by a control unit such as a microcomputer after a lapse of a predetermined time period during which the odor is generated in the ordinary garbage disposal after the switching valve 17 is switched to the first exhaust passage 15. Switching valve 1
7 may be switched to the second exhaust passage 16.

That is, even if the odor of the air exhausted from the exhaust port 23 disappears after the deodorizing operation, it is determined whether this is due to the deodorizing device 18 or whether the odor in the processing tank 1 has really decreased. Since it is difficult without the odor sensor 43 as described above, the deodorization is automatically stopped after a lapse of a predetermined time during which a bad odor is generated in normal garbage disposal, thereby preventing waste of electricity bill. If the odor still exists, the deodorizing operation may be performed again.

In each of the above embodiments, the switching valve 17 is used as the switching means for switching between the first exhaust passage 15 and the second exhaust passage 16. However, for example, in each of the above embodiments, the switching valve 17 is used. An opening / closing valve that opens and closes by air pressure is provided at an exhaust port 28 of the exhaust passage 16, and the dilution fan 2
It is also possible to drive only the exhaust fan 14 to exhaust air and to drive the exhaust fan 14 to exhaust air when no deodorization is performed. The motor 4 is used as a switching drive source for the switching valve 17.
Although 0 is used, a configuration in which the switching valve 17 is driven by a solenoid or the like may be adopted.
