In addition to the hot water tank 20, a controller 21, a seating switch 22 as a selection switch, and the like are provided. The overall control setting can be executed by the user operating the remote controller 23. The setting signal from the remote controller 23 is wirelessly transmitted to the controller 21 using infrared rays. The cross section of the toilet seat base 9 is configured as shown in FIG. An air passage 24 is provided inside, and the outside of the inner surface of the toilet seat base 9 partitioned by the reinforcing rib 25 serves as an air passage. The air outlet 10 is a U-shaped groove that is continuously opened right next to the air outlet 10. Therefore, the air is blown in a film shape. The catalyst deodorizer 15 may be provided on the side of the air passage 16.

Toilet seat base 9 and warm water washing toilet seat body 11
Is mounted on the toilet bowl as shown in the perspective view of FIG. Toilet seat 26, toilet seat lid 2 on the toilet body 11
7 is also attached, and is configured to be entirely fixed on the edge 29 of the toilet 28 with a bolt 30.

Next, the operation of this embodiment will be described. When the user sits on the toilet seat 26, the seating switch 22 is turned on,
The blower 12 starts to rotate in response to a command from the controller 21, and blows air toward the inside of the toilet 28 from the outlet 10 of the toilet seat base 9 through the air passage 16. The air blown into the toilet bowl is immediately sucked through the suction port 13, and the catalyst deodorizer 1
After passing through 5, it reaches the blower 12 again to form a circulation circuit. The bad odor generated from the stool that fell into the toilet 28 during use is such that the air blown from the outlet 10 covers the entire opening surface of the toilet seat base 9 and the odor is prevented from escaping from above the toilet. Thus, even if there is a gap between the crotch or between the toilet seat 26 and the buttocks, it is prevented from going out of the toilet bowl. Further, this bad odor is surely deodorized by repeatedly passing through the catalyst deodorizer 15 as the air circulates. When the user feels cold when the wind hits the human body, such as in winter, or when the user wants to actively warm the human body, on / off and strength adjustment can be performed by the switch operation of the remote controller 2, so the user can select. .. When heating is instructed, the heater 17 operates and hot air is supplied. After the toilet is finished, the nozzle 19 is used for cleaning, but if you want to dry after cleaning, use the remote controller to instruct to dry and blower 12
Rotates at high speed and blows a large amount of warm air locally. In this case also, the air curtain is maintained. When the user stands up after the use of the toilet, the seating switch 22 is turned off, but the air blower 1 is configured so that the deodorization by the catalyst deodorizer 15 is completely performed and the air curtain is configured until the bad odor is completely eliminated.
2 continues operation for a predetermined time. In this case, when the user stands up, the upper surface of the toilet seat opens over a large area, but in order to maintain the air curtain effect, it is necessary to increase the air volume compared to normal use when seated (non-drying). To increase the air volume. Further, the heater 17 is not necessary and is automatically turned off.

The suction port and the air outlet may be provided on the warm water washing toilet seat as in this embodiment, but may be provided on the toilet side.

FIG. 4 shows another embodiment in which the deodorizing device of the present invention is provided on the warm water washing toilet seat side. A warm water washing toilet seat body 32 is provided above the toilet bowl 31, and the blower 3 is provided inside.
3, a catalyst deodorizer 34, a suction path 35, a blower path 36, and the like are provided, and a blowout port 37 is provided. Unlike the above-mentioned embodiment, this air outlet 37 blows air obliquely downward with a flapper 37a to shield the stool 38 with air, and immediately sucks a bad smell from the upper part of the toilet bowl into the toilet room 39.
The bad odor is decomposed by the same action as in the above embodiment.

By providing the blower 33, the suction port, the suction passage 35, the air outlet 37, and the blow passage 36 in the main body of the warm water washing toilet seat as in this embodiment, the warm water washing toilet seat can be installed in comparison with the case of attaching to the toilet side. Just attach it to the existing toilet bowl,
A deodorizing device that completely prevents bad odors can be realized, and the construction is easier and the construction cost is reduced as compared with the case where the toilet bowl is replaced.

In both of the above embodiments, the air outlet 10 or 37 having a specific structure for blowing air into the toilet to prevent odors from escaping from above the toilet and the circulating air circulating through the upper space in the toilet. Deodorizer 1 for deodorizing odor through
5 or 34 prevents the odor in the toilet bowl from escaping into the toilet room. However, the air blown out from the air outlets 10 or 37 through the air outlets 10 and 37 through the upper space inside the toilet does not need to be structured to specify the air blown out upward in the toilet as in the above-described embodiments. If it is an air outlet that blows out the air that becomes the circulating air sucked into the mouths 13 and 39 into the upper space in the toilet, the effect of preventing the odor is inferior to that of the above-mentioned embodiments, but the circulating air gives off the odor and the catalyst Since it circulates through the deodorizers 15 and 34, the escape of odors to the upper part of the toilet bowl is suppressed, and even if the catalytic deodorizers 15 and 34 do not deodorize at one time, the odor is surely deodorized by circulation.

[0024]

Since the deodorizing device of the present invention is constructed as described above, the following operational effects can be expected. (1) A suction path and a ventilation path are connected via a blower between air outlets communicating through the upper space in the toilet to form a circulation path, and a deodorizing means is provided in the suction path or the ventilation path, and the blower is operated. Since the switch for selection is provided, it is possible to suppress the odor that odors are circulated in the circulating air and escape to the upper part of the toilet, and the deodorizing means is circulated so that deodorization can be performed more reliably. Further, the deodorizing effect can be exerted only when necessary, and power consumption can be reduced and damage to functional parts can be reduced. Further, since the structure does not discharge the odor into the toilet room, there is no need for the work to discharge the odor further out of the room, and the installation work can be simple and inexpensive. (2) It has a suction port facing the toilet bowl and an air outlet for suppressing the discharge of odors from above the toilet bowl by the air blown out, and a suction passage and an air passage passage are connected between the both mouths via a blower. Since it has a switch to select the operation of the blower while forming a circulation path by trapping the bad smell in the toilet bowl, it is possible to reliably prevent the bad smell from scattering in the toilet room.
In addition, the deodorizing effect can be exerted only when necessary, and power consumption can be reduced and damage to functional parts can be reduced. (3) Since the deodorizing means is provided in the air circulation path or in the air blowing path, the malodor is not only passed once as in the past, but is also circulated many times, so that the deodorizing effect of the deodorizing means is achieved. The deodorizing means can be made small while improving dramatically. (4) By providing a blower, a suction port, a suction path, an air outlet, and a ventilation path in the main body of the warm water washing toilet seat, it is possible to realize a deodorizing device that can completely prevent foul odors simply by mounting the hot water washing toilet seat on the existing toilet bowl. As compared with the case of exchanging the toilet bowl together, the construction becomes easier and the construction cost can be reduced. (5) By configuring the selection switch with a seating switch, the user can turn it on and off without having to manually operate it. Therefore, the operation can be simplified and the deodorizing device can be reliably operated when deodorization is required. ..
