[17] An odor removing toilet seat 1 according to the present invention comprises a water tank 2 for storing tap water therein, a main body 3 having a seat plate 3a and a cover 3b pivotably mounted to the upper portion thereof, respectively, an excretion opening 4 and a drainage trap 5 formed inside the main body 3, respectively, and a tap water passageway 6 and an injecting hole 7 formed integrally formed on the upper portion of the main body 3, respectively, for allowing tap water to be injected to the excretion opening 4 therethrough.

[18] The odor removing toilet seats 1 of the present invention further comprises an odor suction chamber 10 formed on the upper portion of the tap water passageway 6, the odor suction chamber 10 having a pair of connection holes 14 formed on the underside surface of left and right sides thereof and a plurality of suction holes 11 formed penetratingly thereon so as to be oriented toward the excretion opening 4 for allowing an odor from the excretion opening 4 to be sucked into the odor suction chamber theretrhough; an odor exhaust chamber 12 formed at the lower portion of the main body 3, the odor exhaust chamber 12 having a pair of connection holes 14 formed the top surface of left and right sides thereof and communicating with an end portion of the drainage trap 5 abutting against a sanitary sewer pipe A through a connection pipe 13; and an odor exhaust unit 20 mounted between the odor suction chamber 10 and the odor exhaust chamber 12 in such a manner that the odor suction chamber 10 and the odor exhaust chamber 12 communicate with each other therethrough, the odor exhaust unit 20 including a tubular body 22, a fan 21 mounted inside the tubular body 22, and an upper and lower connection members 23 and 24 integrally mounted to the upper and lower end portions of the tubular body 22 and having its own elasticity, the upper and lower connection members 23 and 24 having an odor suction opening 23 a and an odor exhaust opening 24a formed thereon, respectively, in such a manner as to communicate with the connection holes 14 therethrough.

[19] The odor exhaust unit 20 includes the fan 21 mounted inside the tubular body so as to be rotated by supplying electricity to exert an air suction force, so that an offensive odor from the excretion opening 4 can be exhausted to the sanitary sewer pipe A.

[20] As shown in FIGs. 6 and 7, the odor exhaust unit 20 having the fan 21 is constructed such that it includes the tubular body 22 and the upper and lower connection members 23 and 24 integrally mounted to the upper and lower end portions of the tubular body 22, respectively, and made of elastic material such as rubber. At this time, the upper and lower connection members 23 and 24 has a funnel-shaped odor suction opening 23a and a funnel-shaped odor exhaust opening 24a formed thereon, respectively, in such a manner as to communicate with the connection holes of the odor suction chamber 10 and the odor exhaust chamber 12 therethrough. Further, the odor exhaust unit 20 additionally includes a sensing means 25 mounted below the fan 21, which is fixedly installed on the upper inner portion of the tubular body 22, so as to automatically sense a user by using any one of an infrared ray and heat; and an electronic valve 26 such as a solenoid valve and the like fixedly mounted below the sensing means 25 for controlling the opening and closing of the odor exhaust opening 24a of the lower connection member 24 so as to sense a user when the user is seated on the seat plate 3a of the toilet seat 1 or positioned in front of the main body 3 to transmit a signal, and thus, automatically supply electricity to the fan 21 and the electronic valve 26.

[21] Reference symbol "B" not shown in drawings denotes a typical ventilation pipe, which is communicatingly mounted to the upper outer peripheral surface of the sanitary sewer pipe A, for allowing water to be readily drained therethrough.

[22] In accordance with the removing toilet seat 1, an offensive odor generated from the excretion opening 4 of the toilet seat 1 passes through the odor suction chamber 10, the tubular body 22 of the odor exhaust unit 20, and the odor exhaust chamber 12 by means of the suction force of the fan 21 of the odor exhaust unit 20 to be exhausted to the end portion of the drainage trap 5 of the toilet seat 1, and then passes through the sanitary sewer pipe A and the ventilation pipe B to be finally exhausted to the outside, thereby fundamentally removing an offensive odor of a toilet.

[23] Hereinafter, the operation of the odor removing toilet seat 1 of the invention as constructed above will be described in detail.

[24] When a user is seated on the seat plate 3a of the main body 3 or positioned in front of the main body 3, the sensing means 25 of the odor exhaust unit 20 senses existence of the user to allow power to be supplied to the fan 21 and the electronic valve 26. Subsequently, a suction force is exerted by the means of the operation of the fan 21, and the odor exhaust opening 24a of the lower connection member 24 is opened by means of the driving of the electronic valve 26. At this time, an offensive odor generated from the user's excretions through the excreting opening 4 is sucked into the odor suction chamber 10 of the upper portion of the main body 3 through the suction holes 11, and then passes through the connection holes 14, the odor suction opening 23a of the connection member 23, and the tubular body 22 of the odor exhaust unit 20. Subsequently, the offensive odor is kept being exhausted to the odor exhaust chamber 12 of the lower portion of the main body 3 through the odor exhaust opening 24a of the lower connection member 24, which is opened by the electronic valve 26, and the connection hole 14 communicating with the odor exhaust opening 24a while the fan 21 is kept being driven. Thereafter, the odor emitted from the odor exhaust chamber 12 is exhausted to the end portion of the drainage trap 5 through the connection pipe 13 by means of the driving of the fan 21 and then finally exhausted to the outside of the building through the sanitary sewer pipe A and the ventilation pipe, i.e., typical odor exhaust pipes.

[25] Furthermore, when the user finishes an excretion, the excretions are treated by injecting a tap water of the water tank 2 to the excretion opening 4 through the tap water passageway 6 and the injecting hole 7. Thereafter, when the user leaves the toilet seat 1, the supply of power to the fan 21 and the electronic valve 26 is automatically interrupted since the sensing means 25 does not sense existence of the user any more. And hence, the fan 21 stops its driving in the given time (about in 10 minutes), and the electronic valve 26 is gradually operated to automatically close the odor exhaust opening 24a of the lower connection member 24. The toilet seat as described above is operated such that the offensive odor emitted from the excretion opening 4, the odor suction chamber 10 and the odor exhaust chamber 12 is sufficiently exhausted, and such that the offensive odor or the remaining odor of the odor exhaust chamber 12, the drainage trap 5 and the sanitary sewer pipe A is prevented from flowing backward.

[26] Meanwhile, the odor exhaust unit 20 is mounted at the right and left sides of the main body 3, respectively, in such a manner as to be vertically disposed between the odor suction chamber 10 and the odor exhaust chamber 12, as shown in FIGs. 2 through 4. However, any one of the right and left odor exhaust units 20 may be used as needed. The remaining odor exhaust unit is configured such that the connection hole 14 is simply covered by means of a cover and the like, or such that the upper and lower connection members 23 and 24 having closed ends are mounted on the upper and lower portions of the tubular body 22, respectively, which does not include the fan 21, the sensing means 25 and the electronic valve 26 formed therein. In this case, the upper and lower connection members 23 and 24 do not have the odor suction opening 23 a and the odor exhaust openings 24a formed thereon. As a result, the odor exhaust unit 20 mounted on one side of the main body 3 is not substantially operated even though the outer appearances of the right and left exhaust units look similar or same to each other. Of course, the odor exhaust unit 20 having the fan 21 and the like has to be mounted on both right and left sides of the main body 3 in order to increase the suction force.

[27] In addition, the upper and lower connection members 23 and 24 are made of rubber and the like having its own elasticity as described above. Thus, the odor suction chamber 10 and the odor exhaust chamber 12 are formed on the main body 3, respectively, at the time of manufacturing the main body 3 of the toilet seat 1, and then the odor exhaust unit 20 is forcibly inserted between the connection holes 14 of the odor suction chamber 10 and the odor exhaust chamber 12. Therefore, the odor removing toilet seat 1 can be readily manufactured, and repaired only by replacing the odor exhaust unit 20 when electrical failures occur on the sensing means 25, the fan 21 and the electronic valve 26, thereby providing convenient maintenance and repair of the odor removing toilet seat 1.

[28] While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.

Industrial Applicability

[29] As described above, according to the present invention, the odor suction chamber and the odor exhaust chamber formed on the upper and lower portions of the main body of the odor removing toilet seat, respectively, communicate with each other through the odor exhaust unit having a fan mounted therein so as to allow a bad smell from the excretion opening to be exhausted to the ventilation pipe through the drainage trap and the sanitary sewer pipe, only by replacing the toilet seat without a work for a separate piping facility or a construction of the wall and the like, so that an excellent outer appearance can be obtained and a bad smell of the inside of the toilet seat can be removed, thereby creating a comfortable toilet environment, and effectively exhausting the bad smell generated from the inside of the toilet seat. And also, an odor from the excretion opening is automatically removed by means of a sensing means, so that a comfortable toilet environment can be obtained all the time, thereby increasing user satisfaction, and allowing an odor from the excretion opening to be effectively exhausted.
