Description

Toilet with improved odor absorption structure

[0001] The present invention discloses a technical idea related to a odor-eliminating toilet that immediately absorbs and discharges odors generated during defecation, and more specifically, by employing a sensor, the odors generated during defecation can be automatically absorbed and discharged, and in particular, the odor absorption path is actively improved so that the absorbed odors are discharged through a siphon via a water tank, so that the odors are purified by the washing water in the water tank, and the purified odors are immediately discharged to the outside through the siphon, thereby maintaining and preserving the toilet in a more pleasant state, and the present invention relates to a toilet with an improved odor absorption structure that maximizes convenience and efficiency of use due to ease of handling, use, maintenance, and management and repair resulting from a structure that is 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 in Utility Model Publication 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 the development of 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 create a pleasant surrounding environment by immediately absorbing the foul odor during defecation and quickly discharging it to the outside.

[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 sensors.

[0022]

[0023] 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.

[0024]

[0025] In order to achieve the above-mentioned solution, the configuration of a toilet with an improved odor absorption structure proposed in the present invention is as follows.

[0026]

[0027] The toilet of the present invention is characterized by comprising a body (10) for receiving excrement; a seat (20) for allowing a user to sit; a cover (30) for shielding the upper part of the body; a water tank (40) for supplying stored washing water to the body; a drainage unit (50) for inducing the discharge of washing water and excrement based on the siphon principle; and a purification unit (60) that connects the water tank and the drainage unit with a pipe and sucks odor generated in the body into the water tank via a fan and a motor, and then transmits and discharges the odor captured in the water tank to the drainage unit.

[0028]

[0029] In addition, the body (10) includes a receiving portion (11) that stores some of the washing water and receives the waste; an extension portion (12) that extends to the rear of the receiving portion to allow the water tank (40) to be installed and is connected to the outlet pipe (42) of the water tank to deliver the stored washing water to the receiving portion or to suck up the foul odor generated in the receiving portion and deliver it to the water tank; and a discharge hole (13) that is formed in large numbers along the circumference on the inner side of the upper portion of the receiving portion and supplies washing water or sucks up the foul odor generated in the receiving portion depending on whether the purification unit (60) is driven.

[0030]

[0031] In addition, the seat (20) includes a sensor (21) installed singly or in multiple numbers on the bottom surface and grounded by the load caused by the user sitting, and the sensor (21) is connected to the purification unit (60) so that when the user sits, the grounding is performed and the operation of the purification unit is requested, and when the user stands up, the grounding is released and the operation of the purification unit is requested to be stopped.

[0032]

[0033] In addition, the water tank (40) is installed at the rear of the body (10) and includes a reservoir (41) for storing a set amount of washing water; a discharge pipe (42) extending from the bottom of the reservoir and connected to the body; a stopper (43) for blocking the discharge pipe; a lever (44) for opening and closing the stopper through a user's operation; and an overflow pipe (45) that is vertically installed in the reservoir and has one side connected to the discharge pipe to discharge washing water exceeding the water level to the outside or to transmit odors absorbed from the body to an optional receiving and purification unit (60).

[0034]

[0035] In addition, the purification unit (60) includes a case (61) having an internally empty set shape; a blower (62) built into the case and composed of a fan and a motor; an adapter (63) coupled to an overflow pipe (45) of a water tank (40) to arbitrarily receive an odor sucked in from the body (10); a suction pipe (64) extended from the case and directly connected to the adapter, and sucking in an odor through the discharge hole (13) of the body, the outlet pipe (42), the overflow pipe (45), and the adapter depending on whether the blower is driven; and a discharge pipe (65) extended from the case and directly connected to a drain (50), and receiving an odor from the suction pipe and discharging it through a siphon of the drain.

[0036]

[0037] In addition, the adapter (63) includes a coupling pipe (63-1) that is vertically connected to the upper part of the overflow pipe (45) to receive washing water exceeding the water level in the water tank and deliver it to the overflow pipe; an extension pipe (63-2) that extends horizontally from the side of the coupling pipe and guides a path so that the foul odor sucked from the body (10) moves to the suction pipe by directly connecting the extended part to the outside of the water tank; and a cover (63-3) that is rotatably installed on the upper part of the coupling pipe and is connected to a float (B) to rotate according to the rising or falling of the float due to the water level, thereby shielding the upper part of the coupling pipe.

[0038]

[0039] In addition, the cover (63-3) includes a closing cap (63-3a) that shields the upper part of the coupling tube (63-1); a rotating shaft (63-3b) that extends from one side of the closing cap and is axially connected to the side of the coupling tube; and an extension member (63-3c) that extends from the other side of the closing cap and is connected to the float (B).

[0040]

[0041] In addition, the purification unit (60) operates automatically when the lever (44) of the water tank (40) is operated, but the lever includes a relay switch (44a) that forcibly controls the operation of the purification unit (60).

[0042] In particular, the relay switch (44a) further includes a function to forcibly stop the operation of the purification unit (60) for a certain period of time when the lever (44) is operated to discharge washing water from the water tank (40) even when the sensor (21) of the seat (20) is grounded due to the user's sitting and the purification unit (60) is in operation.

[0043]

[0044] According to the present invention having the above-described configuration, the operation of the purification unit causes odors to be sucked in through the discharge holes of the body, and the sucked odors are purified by the stored washing water as they move through the water tank, and the purified odors are immediately discharged to the outside through the drain, thereby providing the effect of maintaining and preserving the user's living space in a more comfortable manner.

[0045]

[0046] In addition, the present invention has another effect that can actively contribute to cost reduction for users, as it can be installed without replacing or discarding an existing toilet because the odor absorption function is activated simply by connecting the toilet and the purification unit with a pipe.

[0047]

[0048] In addition, the present invention not only removes the foul odor of the toilet through the blower of the purification unit, but also offsets the sound of the stool through the sound of the built-in speaker, thereby contributing to the mental and physical stability of the user, thereby inducing smoother bowel movements and improving the quality of life, which has another effect.

[0049]

[0050] In addition, the present invention not only provides a more convenient and efficient ventilation system by proposing an automatic operation structure utilizing a sensor, but also has another effect of perfectly implementing the intended advanced function with minimal structural improvement, such as by precisely crossing the discharge of washing water and the suction of the purification unit to ensure smooth discharge of washing water and completely blocking the washing water being discharged from penetrating into the purification unit.

[0063] 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.

[0064]

[0065] The present invention discloses a technical idea related to an odor-eliminating toilet that immediately absorbs and discharges odor generated during defecation.

[0066]

[0067] Above all, the present invention can automatically absorb and discharge the foul odor generated during defecation by employing a sensor, and in particular, by actively improving the odor absorption path so that the absorbed foul odor is discharged through a siphon via a water tank, so that the foul odor is purified by the washing water in the water tank, and the purified foul odor is immediately discharged to the outside through the siphon, thereby maintaining and preserving the toilet in a more pleasant state, etc., and it is to be noted that the present invention relates to a toilet with an improved odor absorption structure that maximizes 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.

[0070]

[0071] The above toilet may be manufactured and provided with the purification unit (60) proposed by the present invention, or may be provided as a modified type in which the purification unit is separately installed in an existing toilet.

[0072] Typically, a toilet is composed of a body (10) that receives waste; a seat (20) that allows a user to sit; a cover (30) that shields the upper part of the body; a water tank (40) that supplies stored washing water to the body; and a drain (50) that induces the discharge of washing water and waste based on the siphon principle.

[0073] The purpose of the present invention is to provide a toilet with a purification unit (60) to immediately remove foul odors generated from excrement and to provide a certain sound function, thereby creating a toilet with a comfortable environment and providing mental and physical stability to the user when using the toilet.

[0074] This purification unit (60) has a joint structure that connects a water tank (40) and a drainage unit (50) with a pipe, and sucks the odor generated in the body (10) into the water tank through a self-mounted fan and motor, and then transfers and discharges the odor captured in the water tank to the drainage unit.

[0075]

[0076] As shown in the drawing, the odor is discharged from the body (10) through the water tank (40), the purification unit (60), and the drain (50).

[0077] For example, the body (10) is divided into a receiving portion (11) that stores some of the washing water and receives the waste; an extension portion (12) that extends to the rear of the receiving portion to allow the water tank (40) to be installed and is connected to the outlet pipe (42) of the water tank to transfer the stored washing water to the receiving portion or to suck up the foul odor generated in the receiving portion and transfer it to the water tank; and a discharge hole (13) that is formed in large numbers along the circumference on the inner side of the upper portion of the receiving portion and supplies washing water or sucks up the foul odor generated in the receiving portion depending on whether the purification unit (60) is driven.

[0078] The above-mentioned receiving portion (11) is formed as a circular container, and a set amount of washing water is temporarily stored inside to prevent the user's excrement from getting on the toilet bowl. The receiving portion (11) is connected to a drain portion (50), and when the user requests a drain, the excrement and washing water are discharged simultaneously, and new washing water is supplied from the water tank (40) to replenish it.

[0079] The above extension (12) is the rear portion of the body (10) and has an empty space inside. One side of the extension (12) is connected to the receiving portion (11) by a discharge hole (13), and the other side is connected to the outlet pipe (42) of the water tank (40), thereby providing a supply path for supplying washing water to the receiving portion, and also providing an intake path for transmitting odors from the receiving portion to the water tank.

[0080] The above discharge holes (13) are formed in multiple numbers at set intervals along the upper circumference of the receiving portion (11). The discharge holes (13) supply washing water supplied from the water tank (40) to the receiving portion (11), and also absorb foul odors generated within the receiving portion and transmit them to the water tank (40).

[0081] Meanwhile, the discharge hole (13) may be formed vertically through the upper inner surface of the receiving portion (11) so that the washing water may be discharged vertically or the foul odor may be sucked in vertically, or the discharge hole may be formed diagonally so that the washing water may be discharged in a whirlpool or the foul odor may be sucked in while swirling.

[0082] In general, the body (10) is used only for the purpose of receiving washing water supplied from the water tank (40) through the extension (12) and the discharge hole (13) and discharging it to the receiving portion (11) to wash the excrement excreted by the user. However, in the present invention, it can be used as an odor absorption path that not only provides a washing water supply path but also discharges the odor of the receiving portion to the outside during the time when washing water is not supplied.

[0083] The important point here is that the supply of washing water and the suction of odor must never occur simultaneously. For example, if the suction function for odor is operated simultaneously while the washing water is being supplied, the washing water being supplied to the body will be sucked in together, and the washing water may infiltrate the purification unit (60) made of electronic devices, causing a malfunction or, in severe cases, an electrical leakage accident. Therefore, the supply of washing water and the suction of odor must always operate alternately.

[0084]

[0085] Meanwhile, the purification unit (60) proposed by the present invention may be operated continuously regardless of whether the user uses the toilet or not, or may be operated only for a certain period of time while the user uses the toilet.

[0086] For example, if the system is operated temporarily when the user uses the toilet, the system can be provided normally by a sensor (21) attached to the seat (20), which can effectively reduce power consumption and relieve the user's financial burden to some extent.

[0087] The above sheet (20) includes a single or multiple sensors (21) attached at set intervals to the bottom surface. When multiple sensors (21) are installed, they are arranged at a set interval within the range allowed by the sheet (20), so that perfect sensing is achieved even if the user sits incorrectly.

[0088] The above sensor (21) is structured to be grounded by the load caused by the user sitting, and this sensor is connected to the purification unit (60) via a cable to transmit grounding information caused by the user sitting to the purification unit and request the operation of the purification unit. Conversely, when the user stands up, the grounding is released and the operation of the purification unit (60) is requested to be stopped.

[0089]

[0090] The above water tank (40) is installed at the rear of the body (10) and is divided into a reservoir (41) for storing a set amount of washing water; a discharge pipe (42) extending from the bottom of the reservoir and connected to the body; a stopper (43) for blocking the discharge pipe; a lever (44) for opening and closing the stopper through the user's operation; and an overflow pipe (45) that is vertically installed in the reservoir and has one side connected to the discharge pipe to discharge washing water exceeding the water level to the outside or to discharge odors absorbed from the body into the reservoir.

[0091] The above water reservoir (41) is installed vertically at the upper end of the extension (12) and contains washing water inside. The water reservoir (41) has a discharge pipe (42) installed vertically downward at the lower end to discharge the stored washing water through the discharge pipe, and the discharge pipe is connected to the extension (12) to supply the washing water to the receiving portion (11).

[0092] The above-mentioned outlet pipe (42) has a plug (43) installed at the top to block the upper part of the outlet pipe, thereby temporarily blocking the washing water stored in the reservoir (41) from flowing into the outlet pipe.

[0093] The above plug (43) is connected to the overflow pipe (45) and has a structure that is hinge-connected to the overflow pipe and rotates. The plug (43) is located on the upper side of the outlet pipe (42) adjacent to the overflow pipe (45) 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 (43) is connected to a lever (44) by a chain, and rotates from the overflow pipe (45) depending on the operation of the lever to open and close the upper part of the outlet pipe (42).

[0094] The above lever (44) is provided on the outer upper part of the water tank (40) to allow the user to operate it, and when the lever is operated, the stopper (43) connected to the chain opens and closes, and the washing water in the water tank is discharged. In particular, the lever (44) of the present invention can be connected to a relay switch (44a) electrically connected to the purification unit (60) by a cable, and when the lever is operated, the relay switch detects the discharge of washing water and forcibly stops the operation of the purification unit for a certain period of time.

[0095] In particular, the relay switch (44a) completely prevents the washing water from penetrating into the purification unit by forcibly stopping the operation of the purification unit (60) for a certain period of time when the washing water from the water tank (40) is discharged by operating the lever (44) even when the sensor (21) of the seat (20) is grounded due to the user's sitting and the purification unit (60) is in operation.

[0096] The above overflow pipe (45) is installed in a position adjacent to the outlet pipe (42) inside the reservoir (41), and in particular, the lower side is internally connected to the side of the outlet pipe. The above overflow pipe (33) is formed at a set height within the reservoir (41), and the height becomes the level of the washing water. When the stored washing water level exceeds the height of the overflow pipe, the excess washing water flows into the upper part of the overflow pipe and is discharged to the outside through the outlet pipe (42).

[0097] Meanwhile, since the overflow pipe (45) is in communication with the outlet pipe (42), when the odor suction function of the purification unit (60) is operating, the sucked odor moves in the order of the receiving portion (11), discharge hole (13), extension portion (12), outlet pipe (42), and overflow pipe (45).

[0098]

[0099] The above purification unit (60) is divided into a case (61) having an internally empty set shape; a blower (62) built into the case and composed of a fan and a motor; an adapter (63) coupled to an overflow pipe (45) of a water tank (40) to arbitrarily receive an odor sucked in from a body (10); a suction pipe (64) extended from the case and directly connected to the adapter, and sucking in an odor through the discharge hole (13) of the body, the outlet pipe (42), the overflow pipe (45), and the adapter depending on whether the blower is driven; and a discharge pipe (65) extended from the case and directly connected to a drain (50), and receiving an odor from the suction pipe and discharging it through a siphon of the drain.

[0100] The above case (61) may be formed in various forms, but may be small enough to clearly perform the function of ventilation without infringing on the space of the bathroom. The case (61) is sufficiently sized to accommodate the minimum devices for intake, i.e., a motor and a fan. The case (61) may be fixedly installed at the bottom of the water tank (40), placed on a shelf in the bathroom, or installed by attaching it to the wall of the bathroom. If there is an external requirement that must be applied, it must be waterproof to prevent water from penetrating because it is installed in the bathroom.

[0101] The above blower (62) 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.

[0102] The above adapter (63) is connected to the upper part of the overflow pipe (45) to serve as an overflow pipe that discharges washing water exceeding the water level in the water tank (40) to the outside, and also serves to guide the path so that the foul odor sucked from the body (10) by the blower (62) can move to the suction pipe (64).

[0103] This adapter (63) is vertically connected to the upper part of the overflow pipe (45) to receive washing water exceeding the water level in the water tank and deliver it to the overflow pipe; a connecting pipe (63-1); which extends horizontally from the side of the connecting pipe and guides the path so that the foul odor sucked from the body (10) moves to the suction pipe by directly connecting the extended part to the outside of the water tank; and a cover (63-3); which is rotatably installed on the upper part of the connecting pipe and is connected to a float (B) to rotate according to the rising or falling of the float due to the water level, thereby shielding the upper part of the connecting pipe.

[0104] The above-mentioned coupling pipe (63-1) and extension pipe (63-2) are connected to each other to provide a path for the odor that has entered the coupling pipe through the overflow pipe (45) to move to the extension pipe. Meanwhile, the extension pipe (63-2) is formed in a form that extends upward at a set angle from the side of the coupling pipe (63-1) as shown in FIG. 4, thereby blocking the washing water that has entered the coupling pipe from entering the suction pipe body (64) and the case (61) through the extension pipe.

[0105] The above cover (63-3) is divided into a closing cap (63-3a) that shields the upper part of the coupling tube (63-1); a rotating shaft (63-3b) that extends from one side of the closing cap and is axially connected to the side of the coupling tube; and an extension member (63-3c) that extends from the other side of the closing cap and is connected to the float (B).

[0106] Accordingly, when washing water is supplied to the water tank (40) and the water level rises, the float (B) is raised and lowered to open the closing cap (63-3a), thereby allowing the forced drainage of washing water exceeding the water level. When washing water is discharged by operating the lever (44) and the water level drops, the float is lowered and the closing cap shields the connecting pipe (63-1).

[0107] The above suction pipe (64) may be made of a flexible material, and one end is connected to the case (61), and the other end is directly connected to the extension pipe (63-2) of the adapter (63). By directly connecting the suction pipe (64) to the adapter (63) in this way, suction power is generated, including the adapter (63) and the overflow pipe (45) in a small area, and the water tank (40) in a large area, and the suction power reaches not only the adapter, the overflow pipe, and the water tank, but also the discharge pipe (42), the extension part (12), and the discharge hole (13), thereby effectively sucking up the odor generated in the receiving part (11).

[0108] And as described above, when washing water is supplied from the water tank (40) to the extension (12), the blower (62) is stopped by the sensor (21) or relay switch (44a), so the washing water does not flow into the blower. In addition, the structure in which the extension pipe (63-2) extends upward at a set angle and the height of the suction pipe (64) and the air pressure formed inside the pipe completely block the washing water from flowing into the blower (62), so it is very safe from electric shock accidents.

[0109] The above discharge pipe (65), like the suction pipe (64), can be made of a flexible material, and one side is connected to the case (61), and the other side is connected to a siphon (S) provided in the drainage section (50).

[0110] In particular, the present invention can be installed at the lowest part of the siphon (S). For example, when a user sits on the seat (20), the blower (62) is operated by the sensor (21) to exert a suction function, and this suction power sucks in the bad smell generated from the body (10) and sequentially passes through the discharge hole (13), extension (12), outlet pipe (42), overflow pipe (45), adapter (63), suction pipe (64), and case (61) and is then transmitted to the discharge pipe (65) and ultimately injected into the siphon (S).

[0111] Here, the siphon (S) is a U-shaped pipe, and a small amount of washing water is stored in the banded section. Therefore, since the discharge pipe (65) is connected lower than the banded section where the washing water is stored, even if an unpleasant odor is injected into the siphon, the washing 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 (65) 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 washing water exists among the areas of the siphon (S).

[0112] Meanwhile, the purification unit (60) may be configured with a built-in speaker (66) 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.

[0113] These speakers (66) may be determined to be operational based on the above-mentioned sensor (21), and may be equipped with a Bluetooth function so that wireless control can be performed through a smartphone registered by the user or voice recognition, etc.

[0114] As a result, the toilet of the present invention is composed of a body (10) for receiving excrement; a seat (20) for allowing a user to sit; a cover (30) for shielding the upper part of the body; a water tank (40) for supplying stored washing water to the body; a drainage unit (50) for inducing the discharge of washing water and excrement based on the siphon principle; and a purification unit (60) that connects the water tank and the drainage unit with a pipe and sucks odor generated in the body into the water tank via a fan and a motor, and then transmits and discharges the odor captured in the water tank to the drainage unit.

[0115] In particular, the present invention comprises a purification unit (60) including a case (61) having an internally empty set shape; a blower (62) constructed of a fan and a motor and built into the case; an adapter (63) detachably connected to an overflow pipe (45) of a water tank (40) and temporarily receiving an odor sucked from the body; a suction pipe (64) extending from the case and directly connected to the adapter, and sucking an odor through the discharge hole (13) of the body, the outlet pipe (42), the overflow pipe (45), and the adapter depending on whether the blower is driven; and a discharge pipe (65) extending from the case and directly connected to a drain (50), and receiving an odor from the suction pipe and discharging it to a siphon of the drain; and the adapter (63) is detachably vertically connected to an upper portion of the overflow pipe (45) and a connecting pipe (63-1) receiving washing water exceeding the water level in the water tank and delivering it to the overflow pipe; An extension pipe (63-2) extending horizontally from the side of the coupling pipe and guiding a path so that the odor sucked from the body (10) moves to the suction pipe by directly connecting the extended portion to the outside of the water tank and the suction pipe (64); and a cover (63-3) rotatably installed on the top of the coupling pipe and connected to a float (B) to rotate according to the rising and falling movement of the float due to the water level and shield the upper part of the coupling pipe; and the cover (63-3) is characterized in that it comprises a closing cap (63-3a) shielding the upper part of the coupling pipe (63-1); a rotation shaft (63-3b) extending from one side of the closing cap and axially connecting with the side of the coupling pipe; and an extension member (63-3c) extending from the other side of the closing cap and connected to the float (B).

[0116] The toilet of the present invention, having the above-described configuration, sucks in odors through the discharge hole of the body by the operation of the purification unit, and the sucked odors are purified by the stored washing water in the process of moving through the water tank, and the purified odors are immediately discharged to the outside through the drain, thereby maintaining and preserving the user's living space in a more comfortable manner.

[0117] Additionally, since the odor absorption function is activated simply by connecting the toilet and the purification unit to the pipe, installation is possible without replacing or discarding the existing toilet, which can actively contribute to cost reduction for the user.

[0118] In addition, the purification unit's blower not only removes the foul odor from the toilet, but also cancels out the sound of the stool through the built-in speaker, contributing to the user's mental and physical stability, thereby promoting smoother bowel movements and improving the quality of life.

[0119] In addition, by proposing an automatic operation structure utilizing a sensor, it not only provides a more convenient and efficient ventilation system, but also precisely cross-operates the discharge of washing water and the suction of the purification unit to ensure smooth discharge of washing water and completely block the infiltration of the discharged washing water into the purification unit, thereby perfectly implementing the intended advanced function with minimal structural improvement.

[0120]

[0121] 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.
