The odor removing device 100 for a toilet according to the present invention is characterized in that the odor and bacteria in the main body 110 are sucked and removed by using the overflow pipe 140.

Odor and bacterium (pathogenic bacteria) are generated in the inside of the toilet bowl main body 110 due to urine. Basically, as described above, odor and bacteria are removed to some extent by discharging the excreta together with the washing water through the drain port 114. However, odor and bacteria are completely removed due to various factors, It does not. The malodor removing apparatus according to the present invention operates to supply the suction force to the overflow pipe 140 connected to the inside of the main body 110 through the supply pipe 130 to suck odor and bacteria generated in the main body 110 . The suction force provided to the overflow pipe 140 is generated through the venturi device 170.

At this time, since the venturi device 170 and the overflow pipe 140 are sealed by the sealing member 150, the suction force of the venturi device 170 is completely transferred to the overflow pipe 140, And it has an advantage that it can easily suck odor and bacteria. However, if the upper end of the overflow pipe 140 is always closed with the venturi device 170, the upper end of the overflow pipe 140 is clogged even if the water level of the washing water is higher than a certain level, so that the washing water flows into the overflow pipe 140 And the overflow pipe 140 'overflowing the washing water' may be lost because the washing water overflows from the water tank 120. Accordingly, the sealing member 150 according to the present invention closes the inside of the water tank 120 and the inside of the overflow pipe 140 according to the level of the wash water, or moves the wash water to the supply pipe 130. 3 (a) and 3 (b) illustrate the structure of the overflow pipe, the sealing member, and the venturi device according to an embodiment of the present invention, Respectively.
