To explain the operation of the above configuration, first, when deodorizing during defecation, the damper 32 closes the communication duct 31 and opens the discharge duct 30, as shown by the solid line in FIG. In this state, the blower 16 is operated to generate a flow of air from the suction port 13 to the discharge port 15, and the air containing malodorous components during defecation is sucked from the suction port 13 and flows into the suction duct as shown by the solid arrow. 20・Blower 16・Storage part 21
Flows through the heat exchanger 28, heating means 24, purification section 26, return duct 29, heat exchanger 28, and discharge duct 30. At this time, the malodorous components are adsorbed and stored by the activated carbon 22 in the storage section 21, and the deodorized air is discharged into the toilet room from the discharge port 15. In the figure, the exhaust is discharged into the toilet room, but it may of course be discharged outdoors.

At this time, although the activated carbon 22 in the storage section 21 does not have any deodorizing ability, the oxidation catalyst 27 in the purification section 26 also decomposes the malodorous components. In general, the decomposition ability of an oxidation catalyst increases as the temperature increases, so if the heater 25 is heated by electricity, the deodorizing ability will further increase. However, if you try to heat the product at a high temperature with an electric heater, you will need to use a large-capacity heater or reduce the deodorizing air volume, but this problem can be solved by increasing the temperature of the intake air to the heater 25 using the heat exchanger 28. ing.

When deodorizing is performed several times, the deodorizing ability decreases because the adsorption and storage capacity of the activated carbon in the storage section 22 is limited. Therefore, after a period of time has elapsed, the activated carbon in the storage section 22 is reactivated.

For example, a reactivation switch (not shown) is provided,
When the reactivation switch is turned on, the damper 32 opens the communication duct 31 and closes the discharge duct 30 as shown by the dotted line in FIG. Then, the blower 16 is activated and the heater 25 is energized. The air sent from the blower 16 passes through the activated carbon 22 in the storage section 22 as shown by the arrow, and is heated by the heat exchanger 28.
It is further heated by the heater 25 to become hot air, which warms the oxidation catalyst 27 of the purification section 26 to increase the decomposition processing capacity of the oxidation catalyst. The warm air that has passed through the oxidation catalyst 27 in the purification section 26 returns to the heat exchanger 28 from the return duct 29 and is slightly cooled, and then flows from the communication duct 31 to the blower 16. This circulation operation causes the temperature of the entire circulation path to rise. Then, the warm air warms the activated carbon 22 in the storage section 21 and desorbs the malodorous components adsorbed and stored in the activated carbon 22, reaching the oxidation catalyst 27 in the purification section 26. Here, since the oxidation catalyst in the purification section 23 decomposes the malodorous components, the hot air from which the malodorous components have been removed is again sent to the bypass passage 17, and the malodorous components are repeatedly desorbed and purified by the activated carbon in the storage section 22. The oxidation catalyst in section 23 decomposes malodorous components.

At this time, if the hot air temperature rises too much, the activated carbon will burn, so it is necessary to install a hot air temperature sensor or the like and turn on/off the heater 25 to keep the hot air temperature constant.

Although the time required to reactivate the activated carbon varies depending on the type of activated carbon 220 in the storage section 21, the air volume of the blower 16, etc., the heater 25 is turned off and the blower 16 is turned off at a time estimated from experimental data.
is stopped, and the reactivation of the activated carbon 22 in the storage section 21 is completed.

As described above, according to the embodiment of the present invention, the activated carbon 22 in the storage section 21 can be repeatedly reactivated and used, so that the deodorizing effect can be exhibited for a long period of time. In addition, during reactivation, the activated carbon 2 in the storage section 21 is repeatedly activated while circulating hot air through the communication duct 31.
Since the malodorous components can be desorbed in step 2 and the malodorous components can be decomposed by the oxidation catalyst 27 in the purification section 16, the efficiency of reactivation can be increased and the amount of malodor leaked to the outside can be reduced.
