The present invention relates to a odor removal device for toilet seats, and more particularly, before and after the use of the toilet seat to exhaust the odor remaining in the body of the toilet while operating for a certain time to create a comfortable toilet interior environment. The odor removal device for toilet seats, which has a power-saving function, further improves its functionality, and also reduces the installation cost by exhausting the odors remaining in the body of the toilet through a drain pipe connected to the wash basin of the bathroom. It is about.

In general, many kinds of odors remain in the bathroom, which can be offensive to the user using the bathroom. Therefore, in the past, a deodorizer was used to remove odors remaining in the toilet. In this manner, a large amount of ozone is generated in the process of removing odors, which affects the human body.

Unlike the above, a separate exhaust device is installed on the ceiling to remove the odor generated in the bathroom, and this method is installed on the ceiling regardless of the location of the odor, so that the odor cannot be fundamentally exhausted. The toilet has the drawback that odors always remain in the bathroom.

As a result, recently, as a fundamental countermeasure for removing odors, a separate exhaust device is installed at a position close to the toilet.

Exhaust ducts 22 are formed which guide them.

And the case 24 is formed on the body 4 while the seat 24 is formed integrally to allow the user to sit on both sides.

The seat 24 and the inhaler 14 formed as described above may be integrally manufactured when manufactured, or may be manufactured by separating them prefabricated.

An inlet hose 26 for guiding the flow of odor is connected to the exhaust pipe 22 of the inhaler 14, and an exhaust device 28 for forcibly exhausting the odor is connected to the inlet hose 26.

The exhaust device 28 includes a housing 34 having an inlet pipe 30 connecting the inlet hose 26 and an exhaust pipe 32 to the outside, and inside the housing 34 (see FIG. 4). A fan motor 36 is installed to provide a suction force to exhaust odors. In this case, an inlet 38 and an exhaust port 40 are formed in the fan motor 36, respectively.

The inlet 38 formed as described above is connected to the inlet pipe 30 (see FIG. 3) of the housing 34, and the exhaust pipe 32 is coupled to the exhaust port 40 (see FIG. 4) while the duct 42 is coupled. The damper 44 is installed at the outlet of the duct 42 to prevent the backflow of odor.

Since the damper 44 installed as described above is inclined at a predetermined angle, the outlet side of the duct 42 is closed by its own weight while the fan motor 36 is not operated.

In addition, the fan motor 36 is installed in the housing 34 while the control unit 48 which transmits an operation command is connected, and the operation switch 50 and the power switch 54 are connected to the control unit 48, respectively. The housing 34 is fixedly installed on the upper upper end, and the plug 48 is connected to the control unit 48 so that it can be inserted into an outlet not shown.

In order for the user to use the exhaust device 28 (see FIG. 3) configured as described above more conveniently, the user should install the exhaust device 28 near one of the arms. The fixing screw 57 is fixed to the bent bracket 55, and the bracket 55 is fitted to the fixing pin 10 of the support 8 to be disposed at the upper end of the body 4.

As a result, the exhaust device 28 is located at one side of the body 4 and is in a position close to the user's arm.

Subsequently, an exhaust hose 56 for guiding the flow of odor is connected to the exhaust pipe 32 of the exhaust device 28, wherein the exhaust hose 56 (see FIG. 5A) is taken into consideration in the toilet. Place it under the installed table 60.

A wash basin 58 is installed on the table 60 configured as described above, and a pit wrap 62 is connected to the wash basin 58, and a hose connector 66 is connected to an end of the pit wrap 62. Is coupled while connecting the drain pipe 67, wherein the hose connector 66 is used that is formed of a T-type pipe (T type pipe).

At this time, the hose connector 66 is formed as a nipple (nipple) is installed vertically on the strap (64).

Referring to the operation of the first embodiment of the present invention configured as described above in Figure 6 the flow chart as follows.

First, when the power switch 54 (see Fig. 4) is turned on, a standby state is achieved. (S1)

When the power switch 54 is turned on as described above, the controller 48 commands the standby state.

After the step S1, the control unit 48 determines whether the operation switch 50 is turned on (S2).

After the step S2, the controller 48 moves to step S1 when it is determined that the operation switch 50 is not turned on.

After the step S2, the control unit 48 transmits an on command to the fan motor 36 when it is determined that the operation switch 50 is turned on (S3).

When the fan motor 36 is operated by the command transmitted from the control unit 48 as described above, suction force is generated. As a result, various odors generated in the body 4 of the toilet seat 2 (see FIG. 3) are generated. Collected into the case 18 through the inlet 16 of the inhaler 14, the odor collected as described above moves along the inlet hose 26 through the exhaust pipe 22 and the inlet pipe 30 and the inlet ( 38) (see FIG. 4), the fan motor 36, the exhaust port 40, and the duct 42 are sequentially moved.

Subsequently, the odor is pushed through the duct 42 to push the damper 44 to rotate around the hinge of the hinge 46 to open, and then the odor exits the housing 34 through the exhaust pipe 32. Will go out.

The odor exhausted as described above moves along the exhaust hose 56 connected to the exhaust pipe 32 and then exits to the drain pipe 67 through the hose connector 66 (see FIG. 5A).

At this time, the other end of the hose connector 66 is connected to the pit wrap 62 connected to the wash basin 58, the odor is blocked by the water remaining in the pit wrap 62, the flow to the wash basin 58 side, This causes the odor to escape only through the drain pipe 67 into the sewer. Moreover, when the used water staying in the wash basin 58 is drained, the odor is pushed out by the drained water and then escapes to the sewer.

In the case of the strap 64 shown in Figure 5b also performs the function to prevent the backflow of odor in the same manner as above.

After the step S3, the controller 48 (see Fig. 4) determines whether the operation switch 50 is off (S4).

After the step S4, when the control unit 48 determines that the operation switch 50 is off, the control unit 48 operates the fan motor 36 for 5 minutes and then transmits a stop command. (S5)

When the operation switch 50 is turned off as described above, the control unit 48 stops after operating the fan motor 36 for 5 minutes. As a result, the suction force provided by the fan motor 36 is dissipated. Odor collection through the inlet 16 of (14) (see Fig. 3) is stopped.

Due to the suction force dissipated as described above, the damper 44 returns to its original position by its own weight, thereby causing the inlet of the duct 42 to be in a closed state, which causes exhaust of the odor through the exhaust device 28. The damper 44 stops, and some odor remaining in the exhaust hose 56 flows to the left toilet 2 (see Fig. 3) while being flowed back.

As described above, the operating time of the fan motor 36 may be used by setting a specific time in the controller 48 within a range of about 2-5 minutes in addition to 5 minutes.

After step S5, the control unit 48 (see Fig. 4) moves to step S1 to be in a standby state as in the beginning.

On the other hand, after step S4, when the control unit 48 determines that the operation switch 50 is not off, the control unit 48 determines whether the fan motor 36 has been operated for 20 minutes.

As described above, the situation in which the fan motor 36 has been operated for 20 minutes is determined to be a situation in which the user has left the toilet without turning off the operation switch 50. If not, the fan motor 36 continues to operate to increase power loss.

Therefore, in order to prevent power loss, it is preferable to stop the operation of the fan motor 36 after a certain time elapses. Usually, the operation time of the fan motor 36 is within a specific time within a range of about 10-20 minutes in addition to 20 minutes. It is desirable to set.

After the step S6, the controller 48 moves to step S3 when it is determined that the fan motor 36 has not been operated for 20 minutes.

After the step S6, when the control unit 48 determines that the fan motor 36 has been operated for 20 minutes, it transmits a stop command to the fan motor 36. (S7)

When the fan motor 36 is stopped by the command transmitted from the controller 48 as described above, the odor collection through the inlet 16 of the inhaler 14 (see FIG. 3) is stopped.

After step S7, the controller 48 (see Fig. 4) moves to step S1 and maintains the same state as the first time.

Unlike the above, when the fan motor 36 is stopped while the toilet user stays for a long time, the process as described above may be repeated by turning on the operation switch 50 again.
