Flush toilet with deodorizing function

Abstract

The present invention relates to a flush toilet with a deodorizing function, in which odor exhaust means used to remove an offensive odor is constructed in a compact built-in form in which it is installed inside the toilet body lest it should not seen from the outside, and which can be manufactured using the existing structure of the flush toilet, thereby reducing the manufacturing cost, and thus ensuring economic efficiency.

1 . A flush toilet with a deodorizing function, comprising:
 a water tank configured to store waste wash water;   a toilet body including a toilet bowl formed to fluidically communicate with the water tank and a drain trap extending downwardly from a bottom of the toilet bowl so as to fluidcally communicate with the toilet bowl, the toilet bowl including a plurality of waste wash water jet holes formed on the inner circumference of an upper rim portion thereof so as to allow the wash water supplied from the water tank to be spouted to the inside of the toilet bowl through the water jet holes via a waste wash water passage formed below the water tank and along the inside of the upper rim portion of the toilet bowl; and   an odor exhaust device including an odor exhaust conduit mounted extending downwardly from the toilet bowl while forming a channel of a predetermined length along both sides of the rim portion of the toilet bowl inside the toilet body in such a manner that an upper portion of the channel is formed so as to be opened toward the waste wash water passage and a lower portion of the channel is formed so as to exposed to the bottom of the toilet body and connected in fluidical communication to an exhaust pipe mounted below the floor of a restroom, and an odor exhaust fan mounted at a predetermined position of the odor exhaust conduit and configured to exhaust a foul odor generated from the inside of the toilet bowl to the outside through the exhaust pipe.   
     
     
         2 . The flush toilet according to  claim 1 , wherein the odor exhaust conduit includes at least:
 a pair of vertical pipes disposed vertically in the waste wash water passage;   a pair of horizontal pipes disposed inside both sides of the rim portion of the toilet bowl of the toilet body in such a manner as to extend downwardly from the lower ends of the vertical pipes; and   a single confluent pipe formed by joining the horizontal pipes in such a manner as to extend downwardly from the toilet body and fluidically communicate with the exhaust pipe.   
     
     
         3 . The flush toilet according to  claim 2 , wherein the odor exhaust fan comprises a drive circuit that is turned on or off by a user's manipulation during the use of the flush toilet. 
     
     
         4 . The flush toilet according to  claim 1 , wherein the odor exhaust fan comprises a drive circuit that is driven depending on whether or not the user is detected using a thermal or infrared sensor that is installed at a predetermined position of the flush toilet or the restroom. 
     
     
         5 . A flush toilet with a deodorizing function, comprising:
 a water tank configured to store waste wash water;   a toilet body including a toilet bowl formed to fluidically communicate with the water tank and a drain trap extending downwardly from a bottom of the toilet bowl so as to fluidcally communicate with the toilet bowl, the toilet bowl including a plurality of waste wash water jet holes formed on the inner circumference of an upper rim portion thereof so as to allow the wash water supplied from the water tank to be spouted to the inside of the toilet bowl through the water jet holes via a waste wash water passage;   an odor exhaust pipe unit configured to form exhaust channels having a predetermined shape along the inner walls of both sides of a water tank in such a manner that one ends of the exhaust channels fluidically communicate with the toilet bowl and the other ends thereof extend downwardly along the inner walls of both sides of a lower portion of the toilet bowl so as to be opened toward the inside of a space formed below the toilet bowl; and   an odor exhaust fan motor mounted inside the space hermetically sealed by the bottom of a rest room so as to be connected in fluid communication with an odor exhaust pipe buried blow the bottom of the rest room, so that when a user relieves himself or herself on the flush toilet, foul odor generated from the toilet bowl can be respectively sucked in through the exhaust channels opened toward the space and can be forcibly discharged to the outside through the odor exhaust pipe by the odor exhaust fan motor.   
     
     
         6 . The flush toilet according to  claim 5 , wherein the exhaust pipe unit is integrally formed with the inner wall of the toilet body while forming the exhaust channels along the inner wall of the toilet body when the toilet body is molded, and the exhaust channels are formed bent in an inverted-U shape having a predetermined height. 
     
     
         7 . The flush toilet according to  claim 3 , wherein the odor exhaust fan comprises a drive circuit that is driven depending on whether or not the user is detected using a thermal or infrared sensor that is installed at a predetermined position of the flush toilet or the restroom.
