FIG. 5 shows a conventional toilet bowl 22 in which a lid 19 and a toilet seat 20 are attached by a hinge 21 and the toilet seat cover 3 of the present invention is attached to the toilet seat 20.
Is shown, and the deodorizing drive device 11 is placed on the floor 23 slightly behind the toilet 21.

As for use, when the user tilts the lever of the switch 17 to the position 17 'with his or her hand, the fan 13 is rotated by the motor 14, and the odor in the toilet 22 is absorbed by the odor provided in the pipe at the inner edge of the toilet seat cover. Aspirated from hole 1, perforated pipe 2, flexible tube 10
The odor is deodorized by the activated carbon layer 12, and the fragrance is further given by the fragrance 15 and discharged into the toilet 24, so that the user does not feel an unpleasant odor, and is comfortable with the fragrance. And no stench remains in the room. After the stool, the fan 13 is stopped when the lever of the switch 17 'is returned to the position 17 with the foot. The activated carbon and fragrance can be exchanged.

FIGS. 6 and 7 show an embodiment of the present invention in which the toilet seat cover 25 has an oval ring shape instead of the horseshoe shape as shown in FIG. 3, in which an annular perforated pipe 26 having the odor absorbing hole 1 is inserted. Sewing the pipe 26 to 4
To cover the oval annular toilet seat 28 to form the absorption hole 7. Other deodorizing driving devices and the like are the same as those in the above-described example, and the same numbers are assigned.

8 and 9 show another embodiment of the present invention in which the toilet seat 30 itself is provided with the absorption hole 1. FIG. A lid 19 and a toilet seat 30 are pivotally attached to a toilet 22 by a hinge 21 so as to be openable and closable. Is provided with a T-tube 9. Alternatively, as shown in FIG. 11, the odor absorbing hole 1 and the lead-in channel 2 'corresponding to the pipe 31 are molded on the toilet seat in advance integrally with the toilet seat.

The toilet seat 30 has a support rod 33 extending behind the shaft hole 32 of the hinge, and an odor suction device 34 is provided at an end of the support rod 33.
The pipe 31 and the device 34 are connected by a pipe 35.

The suction device 34 is substantially the same as that of FIG.
Built-in fan 13 and motor 14 for rotating fan 13
The odor in the toilet bowl 22 is sucked by the fan 13 through the pipes 31 and 35 and the deodorant layer 12 and discharged from the exhaust port 16.

In this example, if the device 34 and the like behind the hinge 21 for the toilet seat 30 and the front toilet seat have substantially the same rotational moment M1 and M2, it is light and does not require force when the toilet seat is moved up and down by hand. There is also an effect.

When the moment M1 on the side of the device 34 is larger than the rotational moment M2 of the toilet seat, a suction cup 36 that adsorbs to the edge of the toilet 22 is provided on the lower surface of the toilet seat 30 in front of both sides thereof.

Thus, the moment 30 on the side of the device 34 is applied to the toilet seat 30, but the toilet seat 30 is at the horizontal position by the suction cup. After a while, air gradually enters into the suction cup 36, peels off, and the toilet seat pops up with the lid by the moment M1 due to gravity on the device 34 side, so that the toilet can be urinated without raising the toilet seat by hand.

When the lid is closed, the toilet seat also closes and is fixed by the suction cup. Therefore, when the stool is opened, the toilet seat is stopped by opening the lid.

A few seconds after the toilet is released from the toilet, the toilet seat automatically pops up due to the moment on the device 34 side.

The central portion 37 of the toilet seat 30 is located in front of the toilet bowl 22 in a place where it is easy to get wet with urine, and since there is no suction cup 36 here, the urine does not soak into the space between the suction cup and the rim of the toilet bowl, so that the adsorption is not weakened or dirty. .

Further, a motor 14 is provided on the lower surface of the toilet seat 30 so that the deodorizing device automatically operates only when a person sits on the toilet seat 30 and uses it.
The switch 38 is pressed and turned on by the weight of the person sitting on the toilet seat 30, the fan 13 rotates, and when the person leaves the toilet seat, the pressure switch 38 is turned off and the fan stops rotating. It is supposed to. Reference numeral 39 denotes a power cord with a plug, and a switch 38 is connected to a circuit to the motor 14 by a wiring 40 from now on. The power supply may be a battery type without using household AC.

According to the present invention, it is possible to easily and inexpensively and simply deodorize the toilet simply by putting the cover of the present invention on the toilet seat of the conventional ordinary toilet bowl, or removing the conventional toilet seat from the hinge and replacing it with the toilet seat of the present invention. Efficiency is high because the odor absorbing hole is located in the toilet bowl and faces the toilet surface.

In addition, if the toilet seat is raised after the toilet, the odor absorbing hole is directed upward of the toilet, so that the residual odor in the toilet can be removed.

Further, the present invention has a very large advantage that the deodorized exhaust gas can be released into the toilet because it has been deodorized, and the disadvantage that the temperature in the toilet changes due to the ventilation in the toilet and the load on the air conditioning is increased can be avoided. It is an invention that brings benefits.
