In the above embodiment, before explaining the operation of the present invention according to the flowchart of FIG. 6, only the principle of the deodorizing operation of the present invention will be schematically described. When the user sits on the toilet seat 38, the seat switch 22 is turned on, and the blower 12 starts rotating according to a command from the controller 21, and blows air from the whole of the outlet 10 toward the inside of the toilet through the blowing path 16.
The air blown into the toilet bowl is immediately sucked through the suction port 13, passes through the catalyst deodorizer 15, and returns to the blower 12 to circulate. The bad odor generated from the stool dropped into the toilet during the toilet is like the air blown out from the outlet covers the entire opening surface of the toilet seat base 9 and prevents the odor from being diffused into the toilet room from above the toilet, Even if there is a gap between the crotch or the toilet seat and the buttocks, it will not go out of the toilet. After the stool, the local part is washed with the human body washing nozzle 19, the stool is drained by flushing the toilet bowl, and the toilet bowl is washed with water. Is working.

Next, the main part of the detailed operation of this embodiment will be described with reference to the flowchart of FIG. 6 showing steps S1 to S23.

When the user sits on the toilet seat 26, the seat switch 22 is turned on (S1), and the deodorant switch 33 is turned on (S1).
If 2), the value is read from the air volume preset section 34a (S3), and the operation of the blower 12 is started.
The air volume at this time is set to a small amount because the user is seated. When the air volume change switch 31a is operated (S4) and the air volume is increased or decreased, the air volume according to the new set value is set (S5), and air is blown from the blower 12 (S6). The range in which the air volume can be changed is set to a range where the deodorant effect is not impaired. If the heating switch 29 is turned on while air is being blown (S
7) The set temperature is read from the temperature preset section 34b (S8). If the temperature is lower than the set range, the hot air heater 17 is energized and the heating operation is started. In this case, the temperature of the hot air is detected by the thermistor 46, the deviation from the set value is compared by the temperature comparing unit 47 (S9), and output from the temperature adjusting unit 48 to the hot air heater 17, and the hot air heater 17 is fed back. Controlled. And the temperature deviation is the set value ±
When the temperature reaches 0.5 ° C. (S10), the amount of power to the warm air heater 17 is fixed (S11). When the temperature change switch 31b is operated during use (S12) and the temperature setting is changed, control is performed so that the temperature is set according to the changed set value.

After the stool, washing is performed and the user operates the drying switch 28 to select drying (S13). If the drying direction is selected, the wind direction adjusting dampers 23 and 24 are connected to both sides of the outlet 10 (a U-shaped linear portion). ) Is closed (S14), and the wind blows out from the front of the toilet seat base 9 toward the suction port 13 in a state where the local portion is easily dried. At this time, the preset values of the air volume for drying and the air temperature are read from the air volume / air temperature preset unit 34 (S15), and the blower 12 and the hot air heater 17
Control is performed according to the air volume and the air temperature. When the air volume / air temperature change switch 31c is operated (S16) and the air volume / air temperature is changed, the blower 12 and the hot air heater 17 are controlled according to the changed values. In this embodiment, the air volume and the air temperature are changed in pairs, but may be changed separately.

When the stop switch 30 is pressed (S17), the function being used out of heating and drying is stopped. As long as the stop switch 30 is not pressed, the control operation is continuously performed from the initial state, as is clear from the flowchart of FIG. These flows are performed within a very short time by the operation of the microcomputer. However, if the set temperature is not reached during the heating operation, the process does not proceed to the next drying operation. This is in order to prevent a human body from feeling a cool air if drying is instructed after heating and air is immediately blown at a large air volume for drying. However, since the air volume at the time of seating is set relatively small, and the capacity of the hot air heater 17 is a large capacity for dry use, the time actually required is small.

When the stop switch 30 is pressed, the function being used among heating and drying is stopped. The deodorizing function is stopped by the user stopping use and standing up from the toilet seat 38 or operating the deodorizing switch 33. When the seat switch 22 is turned off (S17), the power supply to the hot air heater 17 is cut off (S18), and the timer unit 43 is started (S19). Subsequently, the preset value of the stop air volume is read from the stop air volume preset section (S20), the air volume of the blower 12 is increased (S21), and a sufficient effect of deodorization can be obtained even when the upper part of the toilet 40 is open. It is devised.
When the time of the timer 43 comes soon, the timer function is stopped (S22), and the operation of the blower 12 is also stopped (S2).
3). The set time of the timer is set in consideration of the time for flushing the toilet 40 after use and the time for the stool to flow off, and the time for the remaining odor to be sufficiently deodorized by the catalyst deodorizer 15. Use a smell sensor instead of this timer,
The predetermined range in which the operation is performed may be determined by using the integrated airflow value.

In the above embodiment, one blower is used, but a plurality of blowers may be used.
Further, an embodiment in which a blower for suction and a blower is provided as an open circuit without forming a circulation circuit via a blower is also conceivable.

The seating detector may be various methods such as a method of directly detecting the state of sitting on the toilet seat mechanically and a method of indirectly detecting the seating using an infrared switch.

The suction port and the air outlet may be provided in the hot water flush toilet seat body 11 as in this embodiment, or may be provided in the toilet.

FIG. 7 shows another embodiment in which the deodorizing device of the present invention described in the above embodiment is provided on the side of a toilet seat with hot water washing.
Therefore, the description of the same parts as those in the above embodiment will be omitted, and only different parts will be described.

On the upper part of the toilet 50, a warm water flush toilet seat body 51 is provided.
Are provided, and a blower 52 and a catalyst deodorizer 5 are provided inside.
3, a suction path 54, a blowing path 55 and the like are provided, and an outlet 56 is provided. The outlet 56 blows air obliquely downward with an electric flapper 57 which is a blowing direction adjusting means, shields the stool 58 with air, and immediately sucks odors.
The odor is decomposed by the same function as in the above cited example. When the seat switch (not shown) is turned off after use, the electric flapper 57 moves upward by a predetermined angle, and at the same time, the air volume of the blower 52 is increased to maintain the deodorization, and the operation of the blower 52 is stopped after a predetermined time. Is done.

As in this embodiment, the warm water flush toilet seat body 51
By installing a functional part on the toilet, it is possible to realize a deodorant device that can completely prevent bad odors by simply attaching a hot water flush toilet seat etc. to the existing toilet compared to the case where it is attached to the toilet side, compared to replacing the toilet The construction becomes easier and construction costs are reduced.
