[Problems to be Solved by the Invention] In the conventional toilet bowl deodorizing device as described above, the air inside the toilet bowl (2) is sucked in by a blower (11), deodorized with a deodorizing agent (IO), and then discharged. Therefore, there is a risk that the life of the deodorizer (9) will be shortened, and there is a problem that it is necessary to use one with a large deodorizing ability.

This invention has been made to solve the above-mentioned problems, and an object thereof is to provide a toilet bowl deodorizing device that can deodorize the inside of the toilet bowl and prevent shortening of the life of the deodorizer.

[Means for Solving the Problems] A toilet bowl deodorizing device according to the present invention includes an air inlet and an air outlet provided at the peripheral edge of a toilet seat, a blower installed in an air path connecting these, and When operated, an air curtain flow is formed in the toilet bowl, and a deodorizer is connected to the air path to deodorize a portion of the sucked air and discharge it into the toilet.

[Function] In this invention, a blower is connected to the toilet seat to form an air curtain flow inside the toilet bowl, and a part of the air sucked into the air passage is deodorized by a deodorizer and discharged into the toilet. The odor rising from inside the toilet bowl is blocked by an air curtain. Moreover, the deodorizer only needs to deodorize a part of the intake air.

[Embodiment] Fig. 1 and Fig. 2 are diagrams showing an embodiment of the present invention. Fig. 1 is a configuration diagram and Fig. 2 is an electric circuit diagram. Parts similar to those of the conventional device are designated by the same reference numerals. show.

In FIG. 1, (15) is a long ring-shaped toilet seat, which has an air inlet (15a) at its inner peripheral edge and an air outlet (15b) at a position opposite to the air inlet (15a). (16) is the suction port (15
a) and a suction air path connected between the blower (11), (17
) is an air branch box connected to the blower (11), (18
) is a deodorizer connected to one outlet of the branch box and has an exhaust port into the toilet, and (19) is the other outlet of the branch box and the toilet!
(15) an air outlet connected between the outlet (15b);
(20) is air curtain flow, and (21) is deodorized air.

In Figure 2, (25) is an AC power supply, (26) is a switch,
(27) is a human body detection contact that closes when a person sits on the toilet seat (5), and is composed of a switch installed on the toilet seat (15) and operated by the person's weight, and other suitable detectors.

(28) is a relay, (28a) is a switching contact that operates when the relay (28) is de-energized or energized;
) has a strong operation terminal (lla) and a weak operation terminal (llb), and is switched by a switching contact (28a).

In the toilet bowl deodorizing device configured as described above, when the toilet bowl (2) is not in use, the switching contact (28a) is connected to the blower (1).
1), and when the switch (26) is turned on, the blower (11) is operated at high power. Now, the air inside the toilet bowl (2) is sucked into the suction air path (16) from the suction port (15a), enters the air outlet path (19) from the first branch box (17), and is blown out from the air outlet (ISB). , an air curtain flow (20) is formed within the toilet bowl (2).

This air curtain flow (20) blocks odor from rising inside the toilet bowl (2). In order to form an air curtain flow (20) that is effective for deodorizing, it is appropriate that the suction air volume Q2 be approximately three times the blowout air volume Q1. For this reason,
The air volume corresponding to the above air volume difference Q, -Q1 passes from the branch box (17) through the deodorizer (18) to the deodorized air (21).
and is discharged into the toilet. Hence the deodorizer (18)
Since it is sufficient to have the deodorizing ability of air with an air volume of Q, -Q,
Long-term use becomes possible.
