Description

Odor-eliminating toilet with a pressurized sensor-based ventilation structure

[0001] The present invention relates to a technical idea of ​​a flush toilet, and more specifically, to an odor-eliminating toilet having a pressurized sensor-based ventilation structure that can immediately eliminate odors generated during defecation by employing a ventilation structure in the toilet itself, and further, by simply operating a lever, fecal discharge by supplying water and odor removal by grounding a sensor are alternately performed, thereby maximizing convenience and efficiency of use due to ease of handling, use, maintenance, and management resulting from a structure differentiated from the existing one.

[0002]

[0003] Typically, a building contains a bathroom, and most bathrooms feature both shower and toilet facilities to ensure adequate living space. These bathrooms must be kept clean at all times, and the installation of ceiling fans is recommended as one way to ensure this.

[0004] The ceiling-type exhaust fan above serves the role of sucking in various foul odors generated in the bathroom and discharging them to the outside. It is generally used to eliminate foul odors generated during defecation, but it cannot be considered a complete solution because it removes foul odors that have already spread inside the bathroom.

[0005]

[0006] For example, Utility Model Publication No. 20-0175303, “Odor Eliminating Toilet,” is published, and the technology is based on a body that temporarily stores excrement while defecating in a state where a certain amount of washing water is stored; a seat that is rotatable around a hinge axis on the upper side of the body to allow a user to sit; and a water tank that stores washing water so that excrement can be easily removed; and is composed of a gas discharge means that is installed on the rear side of the body to discharge odors; and a limit switch that is installed on the seat so that the gas discharge means can effectively operate ‘ON’ and ‘OFF’.

[0007] The above technology can effectively remove odors generated from a toilet through a gas discharge means, thereby relieving users of discomfort caused by odors and maintaining a pleasant interior of the toilet.

[0008] The above technology has a great advantage in that it is a structure that immediately absorbs the foul odor generated within the toilet body, but it has many restrictions during installation and maintenance because the gas exhaust means for discharging the absorbed foul odor must be exposed to the outside of the building.

[0009]

[0010] As another example, Utility Model Publication No. 0114945, “Deodorizing Device for Toilet,” is published. The technology comprises an intake passage formed by perforating a plurality of intake holes inwardly on the bottom of the seat of the toilet, and an intake curved inner tube communicating with the intake passage at the rear end of the seat is folded and inserted into an intake curved outer tube penetrating the cover, and the rear end of the intake curved outer tube is connected to an expansion tube and then connected to the intake tube of a ventilation fan formed with an electromagnet and a blocking plate, so that when a switch is operated on the door, the ventilation fan and the electromagnet are operated, and the odor inside the room and the toilet is sucked in through the plurality of intake holes of the intake passage and discharged through the ventilation fan.

[0011] The above technology can be installed by modifying a regular toilet, and has a great advantage in that it has a structure that immediately absorbs the foul odor generated inside the toilet body, similar to the "odor-eliminating toilet" registered utility model No. 20-0175303, but it has several disadvantages, such as the toilet cover cannot be opened and closed freely, the structure is extremely cumbersome, and a separate ventilation fan must be installed on the wall.

[0012]

[0013] As a result, there is an urgent need for a toilet that is extremely simple in structure so that it can be easily installed on existing toilets, can be installed without damaging the building, and above all, can immediately absorb bad odors when defecating, creating a pleasant environment.

[0014]

[0015] <Prior art literature>

[0016] (Patent Document 1) Utility Model Registration No. 20-0175303 "Odor Eliminating Toilet"

[0017] (Patent Document 2) Utility Model Registration No. 0114945, "Deodorizing Device for Toilets"

[0018]

[0019] The present invention was created to more actively resolve the above-mentioned problems, and its main task is to provide a technology that can maintain a more comfortable toilet by immediately absorbing and discharging the foul odor generated from the toilet to the outside.

[0020]

[0021] In addition, the present invention is implemented with a simple structure so that it can be sufficiently installed in existing toilets, and another challenge is to maximize usability by utilizing an automatic operation system utilizing a sensor.

[0022]

[0023] In addition, another challenge of the present invention is to provide a technology that enables the above-mentioned automatic operation system to be immediately implemented with extremely simple operations, thereby maximizing convenience and efficiency of use.

[0024]

[0025] In addition, the present invention not only solves the fundamental problem of removing bad odor, but also provides a technology that can contribute to the smooth bowel movement of the user by applying various functions.

[0026]

[0027] In order to achieve the above-mentioned solution, the configuration of the odor-removing toilet having a pressurized sensor-based ventilation structure proposed in the present invention is as follows.

[0028]

[0029] The odor-removing toilet of the present invention comprises a body (10) for receiving waste; a water tank (20) storing a set amount of water; a water outlet (30) for supplying water from the water tank to the body; a discharge outlet (40) for discharging waste and water due to a siphon structure; and a ventilation unit (50) that is automatically controlled by a sensor (51) installed vertically in the water outlet to suck in odors within the body and then discharge them through the discharge outlet.

[0030] In particular, the sensor (51) is characterized in that it is pressurized depending on whether the plug (33) that opens and closes the outlet (30) is opened or closed, thereby determining whether it is grounded or not, and controlling the operation of the ventilation unit.

[0031]

[0032] In addition, the water outlet (30) includes a water outlet pipe (31) that connects the water tank (20) and the body (10) to provide a water supply path; an overflow pipe (32) that is installed in the water tank and has one side connected to the water outlet pipe so that when the water level exceeds the water level, it guides the water to be discharged through the water outlet pipe, thereby contributing to the control of the water level; a plug (33) that is rotatably installed on one side of the water outlet pipe to open and close the water outlet pipe and pressurize the sensor (51) of the ventilation unit (50) to ground or not depending on whether it is open or closed; and a lever (34) that opens and closes the water outlet pipe by rotating the plug according to the user's operation.

[0033]

[0034] In addition, the ventilation unit (50) includes a sensor (51) that is vertically installed inside the outlet pipe (31) of the outlet portion (30) and transmits an electric signal by grounding depending on whether the plug (33) that opens and closes the outlet pipe is opened or closed; a case (52) having an empty interior; a blower (53) that is built into the case and is composed of a fan and a motor and automatically operates by receiving an electric signal from the sensor; a suction pipe (54) that extends from the case and is directly connected to the upper part of the body (10) and sucks in an odor inside the body depending on whether the blower is driven; and a discharge pipe (55) that extends from the case and is directly connected to the discharge portion (40) and receives an odor from the suction pipe and discharges it to the siphon of the discharge portion.

[0035]

[0036] In addition, the sensor (51) includes a mating surface (51-1) of a set thickness that is vertically connected inside the outlet pipe (31); an extension surface (51-2) that extends downward at a set angle from the top of the mating surface and is pressurized by a plug (33); a contact surface (51-3) that is bent and extended from the extension surface toward the mating surface and comes into contact with the mating surface when the extension surface is pressed; a contact sensor (51-4) that is installed overlapping the mating surface; and a dog (51-5) that is installed at the end of the contact surface and is grounded with the contact sensor.

[0037]

[0038] In addition, the sensor (51) includes a packing (51-6) having a set diameter that extends eccentrically from the upper end of the coupling surface (51-1) toward the extension surface (51-2) and is fitted into the inside of the outlet pipe (31), thereby contributing to coupling with the outlet pipe.

[0039]

[0040] In addition, the ventilation unit (50) has a built-in speaker (56) to optionally provide a sound function, and includes automatic operation based on whether the sensor (51) is grounded or through voice recognition via Bluetooth.

[0041]

[0042] Meanwhile, the plug (33) is composed of a cover portion (33-1) that is laminated on the upper surface of the outlet pipe (31) and contributes to primary sealing; and a fitting portion (33-2) that extends downward from the cover portion and contributes to secondary sealing as it is inserted into the outlet pipe to a set depth; and the fitting portion (33-2) includes gradually pressurizing a sensor (51) vertically installed inside the outlet pipe for each depth inserted into the outlet pipe, thereby inducing grounding of the contact surface (51-3) of the sensor and the dog (51-5).

[0043]

[0044] According to the present invention having the above-described configuration, the user can not only dispose of feces by simply operating the lever, but also the ventilation unit operates in conjunction to immediately discharge foul odors, thereby creating a more comfortable environment in the restroom.

[0045]

[0046] In addition, the present invention is effective in reducing costs because the ventilation structure for the desired purpose is applied only by connecting the suction pipe and discharge pipe extended from the ventilation unit to the toilet, so the existing toilet can be used as is without replacing it.

[0047]

[0048] In addition, the present invention not only removes the foul odor of the toilet through the blower of the ventilation unit, but also contributes to the mental and physical stability of the user by offsetting the sound of the stool with music through the built-in speaker, thereby inducing smoother bowel movements and improving the quality of life.

[0049]

[0050] In addition, unlike the existing method of installing an exhaust pipe by drilling a hole in the exterior wall of a building to discharge the inhaled foul odor, the present invention discharges the inhaled foul odor through the toilet's exhaust outlet, thereby eliminating damage to the building at the source and is therefore very effective.

[0051]

[0052] As a result, the present invention has the effect of maximizing convenience and efficiency of use due to ease of handling, use, maintenance, and management and repair resulting from a structure differentiated from the existing one.

[0061]

[0062] The advantages and features of the present invention, and the methods for achieving them, will become clearer with reference to the embodiments described in detail below together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but can be implemented in various different forms. The present embodiments are provided only to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims. In addition, like reference numerals refer to like elements throughout the specification.

[0063]

[0064] The present invention discloses the technical idea of ​​a flush toilet.

[0065]

[0066] Above all, the present invention relates to an odor-eliminating toilet having a pressurized sensor-based ventilation structure that can immediately eliminate the odor generated during defecation by employing a ventilation structure in the toilet itself, and further, by simply operating a lever, the discharge of defecation by water supply and the removal of odor by grounding a sensor are alternately performed, thereby maximizing convenience and efficiency of use due to ease of handling, use, maintenance, and management resulting from a structure that is differentiated from the existing one.

[0067]

[0068] FIG. 1 is a perspective view of a odor-treating toilet constructed according to a preferred embodiment of the present invention, FIG. 2 is a perspective view of a ventilation unit proposed by the present invention, FIG. 3 is a cross-sectional view of a odor-treating toilet proposed by the present invention, FIG. 4 is an example diagram of a sensor proposed by the present invention, and FIGS. 5 to 8 are diagrams showing a structure example of a sensor installed in a water tank and an example of the operation of the sensor.

[0069]

[0070] The odor-treating toilet of the present invention is characterized by supplying water from a water tank with a simple action of the user operating a lever to treat feces inside the toilet, and while the water is being replenished in the water tank, a sensor attached to the water tank is grounded, causing the ventilation system to automatically operate, thereby sucking in the feces generated inside the toilet, and discharging the sucked-in feces together with the water.

[0071] These odor-treating toilets may be supplied with a ventilation unit (ventilation system) installed during production, or they may be provided as a retrofit that allows the ventilation unit to be easily connected to an existing toilet to provide ventilation function.

[0072] The above-mentioned odor-treating toilet comprises a body (10) for receiving waste; a water tank (20) storing a set amount of water; a water outlet (30) for supplying water from the water tank to the body; a discharge outlet (40) for discharging waste and water due to a siphon structure; and a ventilation unit (50) that is automatically controlled by a sensor (51) installed vertically in the discharge outlet to suck in odors within the body and then discharge them through the discharge outlet.

[0073] In particular, as mentioned above, the sensor (51) is pressurized by the opening or closing of the plug (33) that opens or closes the outlet (30), and grounding or non-grounding is determined, and the ventilation unit (50) is automatically controlled to be driven or stopped depending on the presence or absence of grounding.

[0074]

[0075] The above body (10) is composed of a receiving portion (11) for temporarily receiving the user's waste; a plurality of outlets (12) formed along the upper circumference of the receiving portion to supply water provided from a water tank (20) into the receiving portion; and an extension portion (13) that connects the receiving portion and the water tank, communicates with the outlets to transfer water from the water tank to the outlets, and is connected to a ventilation unit (50) by a pipe to suck up odors through the outlets and then guide them to the ventilation unit.

[0076] The above-mentioned receiving portion (11) is formed as a circular body, and a set amount of water is temporarily stored inside to prevent excrement from getting on the toilet bowl. The receiving portion (11) is connected to a discharge portion (40), and when a user requests a drain, excrement and water are discharged simultaneously, and new water is supplied from a water tank (20) to replenish the water.

[0077] The above-mentioned outlet holes (12) are formed in multiple numbers at set intervals along the upper circumference of the receiving portion (11), and water from the water tank (20) is supplied to the receiving portion through these outlet holes, and also the foul odor generated within the receiving portion is sucked in and discharged to the ventilation unit (50).

[0078] The above extension (13) is the rear part of the body (10), and its interior is made of an empty space. One side is connected to the receiving part (11) by the outlet hole (12), and the other side is connected to the water tank (20) by the outlet pipe (31). The above extension (13) receives water from the water tank (20) and supplies it to the receiving part (11) through the outlet hole (12), and when the outlet pipe (31) is blocked and the supply of water is stopped, it sucks in the odor from the receiving part through the outlet hole and transmits it to the ventilation unit (50).

[0079]

[0080] The above water tank (20) is installed and secured to the upper part of the extension part (13), and an empty space is provided inside so that a set amount of water can be stored. The water tank (20) has a water outlet (30) installed vertically downward at the bottom to move the stored water in the order of the extension part (13) and the water outlet (12) and supply it to the receiving part (11).

[0081]

[0082] The above-mentioned water outlet (30) is composed of a water outlet pipe (31) that connects the water tank (20) and the body (10) to provide a water supply path; an overflow pipe (32) that is installed in the water tank and has one side connected to the water outlet pipe so that when the water level exceeds the water level, it guides the water to be discharged through the water outlet pipe, thereby contributing to the control of the water level; a plug (33) that is rotatably installed on one side of the water outlet pipe to open and close the water outlet pipe and pressurize the sensor (51) of the ventilation unit (50) to ground or not depending on whether it is open or closed; and a lever (34) that opens and closes the water outlet pipe by rotating the plug according to the user's operation.

[0083] The above-mentioned outlet pipe (31) is made of a pipe with a set diameter, one side of which is installed to extend vertically downward from the bottom of the water tank (20), and the other side is connected to the extension (13) of the body (10) to provide a path for supplying water stored in the water tank to the extension, the outlet (12), and ultimately to the receiving portion (11).

[0084] The above overflow pipe (32) is installed inside the water tank (20) and its lower side is connected to the outlet pipe (31). The overflow pipe (32) is formed at a predetermined height, and when the water stored in the water tank (20) exceeds the height of the overflow pipe, the excess water flows into the overflow pipe and is drained through the outlet pipe (31). Therefore, the height of the overflow pipe (33) becomes the water level of the water tank (20).

[0085] The above plug (33) is connected to the overflow pipe (32) and has a structure that is hinge-connected to the overflow pipe and rotates. The plug (33) is located on the upper side of the outlet pipe (31) adjacent to the overflow pipe (32) and opens or blocks the upper part of the outlet pipe depending on the position at which it rotates from the overflow pipe. This plug (33) is connected to a lever (34) by a chain, and rotates from the overflow pipe (32) depending on the operation of the lever to open and close the upper part of the outlet pipe (31).

[0086] Here, the plug (33) is composed of a cover part (33-1) that is laminated on the upper surface of the outlet pipe (31) and contributes to the primary sealing; and a fitting part (33-2) that extends downward from the cover part and contributes to the secondary sealing as it is inserted into the outlet pipe to a set depth; and the fitting part (33-2) gradually pressurizes the sensor (51) vertically installed inside the outlet pipe for each depth it is inserted into the outlet pipe, thereby inducing grounding of the contact surface (51-3) of the sensor and the dog (51-5).

[0087]

[0088] The above ventilation unit (50) is vertically installed inside the outlet pipe (31) of the outlet portion (30), and is composed of a sensor (51) that is grounded and transmits an electric signal depending on whether a plug (33) that opens and closes the outlet pipe is opened or closed; a case (52) having an empty interior; a blower (53) that is built into the case and is composed of a fan and a motor and automatically operates by receiving an electric signal from the sensor; a suction pipe (54) that extends from the case and is directly connected to the upper part of the body (10) and sucks in an odor inside the body depending on whether the blower is running; and a discharge pipe (55) that extends from the case and is directly connected to the discharge portion (40), and receives an odor from the suction pipe and discharges it to the siphon of the discharge portion.

[0089] The above sensor (51) is a ground sensor that transmits a request for setting through grounding between a contact sensor and a dog, and is composed of a mating surface (51-1) of a set thickness that is vertically connected inside a water outlet pipe (31); an extension surface (51-2) that extends downward at a set angle from the top of the mating surface and is pressurized by a plug (33); a contact surface (51-3) that is bent and extended from the extension surface toward the mating surface and comes into contact with the mating surface when the extension surface is pressed; a contact sensor (51-4) that is overlapped and installed on the mating surface; and a dog (51-5) that is installed at the end of the contact surface and is grounded with the contact sensor.

[0090] As described above, when the sensor (51) is shielding the outlet pipe (31) with the plug (33), the extension surface (51-2) from the plug is pressed and the contact surface (51-3) is brought into close contact with the joining surface (51-1), so that the contact sensor (51-4) is kept grounded to the dog (51-5).

[0091] And when the user requests the discharge of water by operating the lever (34), and the plug (33) is detached from the discharge pipe (31) and the discharge pipe is opened, the pressure of the plug that was pressing the extension surface (51-2) is removed, and the contact surface (51-3) is detached from the joining surface (51-1), and as a result, the contact sensor (51-4) and the dog (51-5) are separated from each other and become in a non-grounded state.

[0092] Accordingly, when the toilet is not normally used, the plug (33) blocks the outlet pipe (31) so that water can be stored in the water tank (20), and the plug pressurizes the sensor (51) installed in the outlet pipe, so that the contact sensor (51-4) and the dog (51-5) are kept in a grounded state.

[0093] As long as the sensor (51) is grounded, the blower (53) continues to operate to provide ventilation. This is because the plug (33) blocks the outlet pipe (31), thereby restricting the supply of water, allowing the blower (53) to smoothly deliver suction power to the extension (13), outlet (12), and receiving portion (11).

[0094] On the other hand, when the user requests the discharge of water by operating the lever (34), the plug (33) is detached from the discharge pipe (31), and the contact sensor (51-4) and the dog (51-5) are separated from each other and become ungrounded, the blower (53) is immediately stopped, and the suction power provided to the extension (13), the discharge hole (12), and the receiving part (11) is blocked. Accordingly, the water supplied through the discharge pipe (31) is blocked from being sucked into the ventilation unit (50) while moving to the extension (13), the discharge hole (12), and the receiving part (11).

[0095] Meanwhile, the sensor (51) includes a packing (51-6) having a set diameter that extends eccentrically from the upper end of the coupling surface (51-1) toward the extension surface (51-2) and is fitted into the inside of the outlet pipe (31), thereby contributing to coupling with the outlet pipe.

[0096] The above-mentioned case (52) may be configured in various forms, but is configured to be small enough to clearly function as a ventilation device without infringing on the space of the bathroom. The case (52) only needs to be capable of accommodating the minimum intake devices, i.e., a motor and a fan. It may be fixedly installed under the water tank (20), placed on a shelf in the bathroom, or attached to the wall of the bathroom. The essential requirement is that it be configured in a form that is isolated from the outside.

[0097] The above blower (53) may be composed of a fan having multiple blades that causes air flow in the surrounding area, and a motor that rotates the fan by power and is coupled to a shaft.

[0098] The above suction pipe (54) may be made of a flexible material, and one end is connected to the case (52), and the other end is connected to the extension (13). By installing the suction pipe (54) in the extension (13), suction force is generated in the extension and the outlet (12), thereby sucking up the odor generated in the receiving portion (11) of the body (10). In addition, as described above, when water is supplied from the water tank (20) to the extension (13), the blower (53) is stopped by the sensor (51), so that the water does not flow into the blower. In addition, since the height of the suction pipe (54) and the air pressure formed inside the pipe prevent water from flowing into the blower (53), it can be used safely.

[0099] The above discharge pipe (55) may be made of a flexible material, similar to the suction pipe (54), and one side is connected to the case (52), and the other side is connected to a siphon (S) provided in the discharge section (40).

[0100] In particular, the present invention can be installed at the lowest part of the siphon (S). For example, when the user operates the lever (34), the blower (53) operates to perform a suction function, and this suction force draws in the foul odor generated from the body (10), and sequentially passes through the outlet (12), extension (13), suction pipe (54), and case (52) before being transmitted to the discharge pipe (55) and ultimately injected into the siphon space.

[0101] Here, the siphon (S) is a U-shaped pipe, and a small amount of water is stored in the banded section. Therefore, since the discharge pipe (55) is connected lower than the banded section where the water is stored, even if an unpleasant odor is injected into the siphon, the water is stored in the banded section of the siphon, so the unpleasant odor does not flow back into the toilet, but is completely discharged to the outside. In other words, the discharge pipe (55) proposed in the present invention further includes a configuration that can be arbitrarily arranged by the user's selection in a set section where no water exists among the areas of the siphon (S).

[0102]

[0103] Additionally, the ventilation unit (50) of the present invention may be configured to have a built-in speaker (56) to optionally provide an audio function. The audio function may be a song or music, or a pre-recorded guidance sound. The song or music may be used to offset the sounds that may occur during defecation, thereby contributing to the user's mental and physical stability, thereby promoting smoother defecation. The audio guidance may also be used to guide the user on how to use the toilet or its functions.

[0104] These speakers (56) may be determined to be operational based on the sensor (51) described above, and may be equipped with a Bluetooth function so that wireless control can be achieved through a smartphone registered by the user or voice recognition, etc.

[0105]

[0106] The odor-treating toilet of the present invention, configured as described above, not only processes waste with the user's simple act of operating a lever, but also immediately discharges odors through the combined operation of a ventilation unit, creating a more pleasant bathroom environment. Furthermore, simply connecting the suction and discharge pipes extended from the ventilation unit to the toilet achieves the desired ventilation structure, allowing existing toilets to be used as is without replacement, saving costs.

[0107] Furthermore, the ventilation unit's blower not only eliminates toilet odors, but also provides music to offset the sound of stool through the built-in speaker, contributing to the user's mental and physical well-being and promoting smoother bowel movements, thereby improving the user's quality of life. Furthermore, unlike the conventional method of installing an exhaust pipe through a building's exterior wall to expel inhaled odors, this system eliminates damage to the building by discharging the inhaled odors through the toilet's exhaust outlet.

[0108] As a result, convenience and efficiency of use are maximized due to ease of handling, use, maintenance, and management resulting from a structure that is differentiated from existing ones.

[0109]

[0110] The present invention described above has been described with reference to one embodiment illustrated in the drawings, but this is merely exemplary, and it should be made clear that various modifications and equivalent other embodiments are possible for those skilled in the art. Therefore, the true technical protection scope of the present invention should be interpreted by the appended claims, and all technical ideas within a scope equivalent thereto should be construed as being included within the scope of the present invention.

The above ventilation unit (50) is vertically installed inside the outlet pipe (31) of the outlet portion (30), and includes a sensor (51) that is grounded and transmits an electric signal depending on whether the plug (33) that opens and closes the outlet pipe is opened or closed; a case (52) having an empty interior; a blower (53) that is built into the case and is composed of a fan and a motor and automatically operates by receiving an electric signal from the sensor; a suction pipe (54) that extends from the case and is directly connected to the upper part of the body (10) and sucks in an odor inside the body depending on whether the blower is operating; and a discharge pipe (55) that extends from the case and is directly connected to the discharge portion (40) and receives an odor from the suction pipe and discharges it through the siphon of the discharge portion. The above sensor (51) is a odor-removing toilet having a ventilation structure based on a pressurized sensor, including a joining surface (51-1) having a set thickness that is vertically connected inside a water outlet pipe (31); an extension surface (51-2) that extends downward at a set angle from the top of the joining surface and is pressurized by a plug (33); a contact surface (51-3) that is bent and extended from the extension surface toward the joining surface and comes into contact with the joining surface when the extension surface is pressurized; a contact sensor (51-4) that is overlapped and installed on the joining surface; and a dog (51-5) that is installed at the end of the contact surface and is grounded with the contact sensor.

2. In paragraph 1, The above outlet (30) is A water outlet pipe (31) that provides a water supply path by connecting the water tank (20) and the body (10); An overflow pipe (32) installed inside a water tank and connected to a water outlet pipe on one side, which contributes to controlling the water level by guiding water discharge to the water outlet pipe when the water level exceeds the water level; A plug (33) that is rotatably installed on one side of the outlet pipe to open and close the outlet pipe and pressurize the sensor (51) of the ventilation unit (50) depending on whether the outlet pipe is opened or closed, thereby causing it to be grounded or ungrounded; A lever (34) that opens and closes the outlet pipe by rotating the plug according to the user's operation; An odor-eliminating toilet having a pressurized sensor-based ventilation structure including a .

3. In paragraph 1, A deodorizing toilet having a ventilation structure based on a pressurized sensor, wherein the sensor (51) has a packing (51-6) of a set diameter that is eccentrically formed to extend from the upper end of the coupling surface (51-1) toward the extension surface (51-2) and is fitted into the interior of the outlet pipe (31), thereby contributing to coupling with the outlet pipe.

4. In paragraph 1, The ventilation unit (50) is a deodorizing toilet having a pressurized sensor-based ventilation structure that includes a built-in speaker (56) to optionally provide an audio function and is automatically operated by grounding the sensor (51) or through voice recognition via Bluetooth.
