Description

The present invention relates to a toilet odor removal apparatus, and more particularly, in a direct water toilet utilizing the water pressure of a tap water, protects the human body from bacteria by inhaling and removing odors and bacteria generated during stool, and a comfortable environment The present invention relates to a odor removal apparatus for a direct water toilet that has been improved to be a toilet.

In general, a toilet bowl (referred to as a Western style toilet bowl) refers to a seated Western style flush toilet where a person sits down and uses a toilet, but is not limited to this and includes other types of toilet bowls that use water.

Such toilets are provided at the upper end of one side of the toilet body, toilet seat for the user to sit on for toilet, excrement discharged into the septic tank with sound water supply, supply water is stored, drained In general, it consists of a water storage tank that discharges excreta into the septic tank.

Such a toilet has a structure in which large and small urine discharged from the body excretory organ (Eliminary Organ) is temporarily stored during the stool and then discharged, so that it emits a terrible odor during the stool, various pathogenic bacteria (Pathogenic Bacteria) As far as it is known, Salmonella, Escherichia coli, Shigella, Glosaridium, etc. are easy to propagate. ing.

However, these pathogens may be harmful depending on the health condition of the user, but there are various skin diseases, respiratory diseases, etc. that can be induced by these pathogens. Gives terrible discomfort.

In this regard, many techniques such as Patent Documents 1 to 5 have been disclosed as techniques for removing malodors generated during stool.

However, the disclosed technology has adopted a method such as chemical treatment, ultraviolet treatment, or ultrasonic cleaning as a means for deodorizing or sterilizing, sterilizing, and antibacterial in order to remove malodors and pathogens, While the structure is complicated and the manufacturing cost is increased, the effect is not great.

For this reason, most users prevent the spread of pathogenic bacteria throughout the toilet by operating the lever with the lid of the toilet seat closed after toilet, and discharging the excrement, but this is a phenomenon where pathogenic bacteria spread This is due to various reports and media reports that when the toilet seat lid is closed, it is reduced more than twice when the toilet seat lid is not closed.

However, because there is an inconvenience that the toilet seat lid must be closed every time, most users often find it cumbersome and cumbersome and do not close the toilet seat lid, and be aware of the act of closing the toilet seat lid. In reality, the act of closing the toilet seat cover itself is not easy because it should be often forgotten.

In order to improve it, the present applicant has applied for a number of patents, including Patent Documents 6 to 8, based on the results of many years of research.

On the other hand, all the toilets described above are equipped with a water storage tank, and the excretion is processed by flowing the water stored in the water storage tank, but this is not only wasteful of water and weak in water pressure, but also installed In order to occupy a lot of space, a direct-water toilet that supplies water only when necessary by connecting water pipes directly without using a water storage tank is also common.

For example, as shown in FIG. 1, a direct water toilet has a water supply pipe 20 for supplying water to the toilet main body 100 on the rear side of the toilet main body 100, and the water supply pipe 20 has a valve body 300 as a medium. It is directly connected to the straight water pipe 40 which is a water pipe, and after the stool, by pushing the lever 32 provided on the valve body 300, the water pressure applied to the water pipe acts as it is and the water is supplied to the excrement. Will be discharged.

Such a structure is simple as described above, does not occupy a lot of installation space, has a great water pressure, and has an excellent discharge capacity.

However, in the case of such a direct water toilet, it is difficult to provide a device for removing malodor.

In the case of the water tank type, it is possible to search for a method of removing malodor using the water tank, but since there is no water tank in the direct water type, at least the attachment / detachment disclosed in Patent Documents 9 to 10 Even a deodorizing device cannot be realized.

However, since the disclosed detachable type is a structure that can be attached to and detached from the toilet body, it is very inconvenient and poor in appearance when sitting, especially in the case of men who stand and urinate. Since the urine is scattered, the sanitation is not clean.

Recently, water-saving toilets have been disclosed by government measures, but water-saving toilets supply water for cleaning the interior of toilet bodies made of earthenware through a different route from discharge water to prevent waste of water. It is a form designed to.

In other words, when a general toilet bowl is flushed with water, the water contained in the water storage tank flows down into the toilet body, and a part of the water passes through a number of washing water holes formed around the inner wall surface of the toilet body. By simultaneously flowing down, excrement flows into the sewage ditch of the toilet, and the other part is configured to wash the inner wall surface of the toilet body.

For this reason, in this structure, the water storage tank should be designed in consideration of the wash water, and the waste of water is severe, which contributes to accelerating the increasingly serious water shortage phenomenon. Therefore, a water-saving toilet was disclosed as an improvement measure.

However, a lot of malodor removal techniques in the toilet bowl of a general form have been developed. On the other hand, the malodor removal technique in such a structure is a weak situation, and an improvement is demanded.

Korean Published Patent No. 2004-0103432 Published Patent No. 2010-0049464 Published Patent No. 2010-0106892 Korean registered patent No. 0568252 Korean registered utility No. 0393220 Registered Patent No. 1502302 Registered Patent No. 1382669 Registered Patent No. 1409515 Registered Patent No. 1058923 Japanese Published Patent No. 1996-277563

The present invention was created to solve the above-described problems, and is simple and easy to install and use because of its structural simplicity, and can be manufactured at a low cost. It is an object of the present invention to provide a malodor removal device for a direct water type toilet bowl which is excellent in the effect of removing pathogenic bacteria, protects the human body, and maintains the toilet usage environment comfortably.

In the present invention, it is confirmed that the toilet is in use through a sensor or the like, and air containing bad odor is inhaled while water is not supplied to the toilet body by the control of the control unit, and is immersed in the water storage means. It aims at discharging through the discharging means provided in the state.

In addition, the present invention provides a 2-way type toilet odor removal apparatus which is improved to quickly inhale and remove odor generated after stool before spreading inside the toilet in a water-saving 2-way toilet. The purpose is to do.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, when assigning reference numerals to the components of each drawing, it should be noted that the same components are given the same reference numerals as much as possible even if they are shown on other drawings. In describing embodiments of the present invention, detailed description of substantially the same contents is omitted.

Also, when a component is described as “connected”, “coupled”, “coupled” or “contacted” with another component, the component is directly coupled or connected to the other component. However, the same technical idea should be understood when other components are “directly”, “coupled”, “coupled” or “contacted” between the components.

Further, when a component is described as being designed, equipped, formed, or configured, it should be interpreted as having substantially the same meaning unless otherwise defined.

Further, in the present invention, the meaning of “comprising” is an open meaning that other components / components can be additionally included in addition to the components and components.

For example, the expressions “upper end”, “upper end”, “lower end”, or “lower end” used in describing the invention not only indicate an end portion of the configuration, but also a portion of the configuration (upper, Lower part etc.), which should be construed throughout the entire content of the invention. That is, it should be interpreted as a term indicating not only the end portion of the configuration but also the corresponding position portion of the configuration.

The floating ball referred to in the description of the present invention is an example of a toilet water level adjusting means, and the case where the floating ball is replaced with another means also corresponds to the technical idea of the present invention.

As shown in FIGS. 2 and 3, the odor removal apparatus for a direct water toilet according to a preferred embodiment of the present invention includes a toilet body 100.

The toilet main body 100 has a generally known structure as it is, and after storing a certain amount of water inside, the excrement after the user's stool is discharged to the sewage tank. Composed.

At this time, in the present invention, the small water tank 200 is provided as one of the water storage means.

Unlike the conventional water tank, the small water tank 200 is significantly smaller in size and is different from the conventional water tank in that it uses direct water.

Therefore, it should be understood that there is almost no restriction on the installation space, and that there is a deodorizing module that sucks off bad odors while water passes. 3, since the air hole 240 is blocked by the operation of the floating ball 220 which is one of the water level adjusting means of the toilet, the water pressure of the water supply is used, so that the present invention is also applied. It can be said that this is one direct water system that uses the water pressure of the water supply.

However, it is not a form in which the two are partly merged, but is clearly a new invention in that it is improved to use straight water, and will be described later.

That is, a valve body 300 which is a kind of means for controlling the opening and closing of water connected to a direct water pipe (water pipe) is connected to one side surface of the small water tank 200 which is an example of water storage means. The body 300 is provided with a lever 310 which is a kind of user command input means. In the present invention, the lever may be replaced with a push mold or other device, and is an example of a command input means for a user to open / close the valve. In addition, the valve body is an example of a control unit that opens and closes water, and may be replaced by another unit.

Therefore, when the lever 310 is pressed, water is supplied while the water pressure of the direct water pipe is applied, water is supplied to the inside of the small water tank 200, and is discharged to the toilet body through the water supply pipe. That is, since the discharge is discharged by the water pressure, the embodiment of the present invention also corresponds to the direct water type.

In addition, a water supply pipe 210 is piped through one side, lower part or lower end surface of the small water tank 200, and one end, lower part or lower part (lower end) of the water supply pipe 210 is connected to the toilet body 100. Connected.

Here, the other side, upper part, or upper end (upper end) of the water supply pipe 210 should be maintained at a predetermined height from the bottom surface of the small water tank 200.

Here, the predetermined constant height may be such that the discharge port 265 is immersed in water (immersion).

This is a completely different concept from the conventional water tank type toilet, and in the present invention, a constant height of water is always contained in the bottom of the small water tank 200, whereas in the conventional water tank type toilet, Since sufficient water pressure cannot be obtained unless all or substantially all of the water is drained (not collected) at the bottom of the tank, the upper end of the water supply pipe is piped so that it matches the bottom of the water tank. It was a structure. On the other hand, in the present invention, water is discharged by the water pressure of the tap water. Therefore, the structure of the water tank is changed and the inlet of the water supply pipe is positioned at a predetermined height. In this case, water is used to dissolve the malodor supplied through the discharge port 256 which is an example of the discharge means provided in the aspirator which is an example of the air suction and discharge means.

A floating ball 220 that opens and closes the water supply pipe 210 is installed at the upper end of the water supply pipe 210.

In addition, an air hole 240 for introducing external air is opened in the ceiling surface of the small water tank 200 in order to eliminate internal pressure.

Meanwhile, an aspirator 250 which is an example of an air suction / discharge unit is installed in the small water tank 220.

The aspirator 250 is a general name of a unit capable of inhaling a kind of air, and sucks off bad odor remaining inside the toilet body 100 through the water supply pipe 210 and discharges a connecting pipe 254 which is an example of a connecting means. It is guided to the small water tank 200 through a plurality of discharge pipes 256 as means, and is dissolved in water stored at a constant height on the bottom.

Therefore, it is a unit that discharges a part of the internal air purified by dissolving bad odors to the outside through the air hole 240 while being purified.

Therefore, the air hole 240 is a very important configuration, and the internal pressure of the small water tank 200 is changed by the operation of the aspirator 250 which is an air intake / exhaust means (for example, when the internal pressure increases, bad odor is generated). When the mixed gas contained therein is no longer sucked), the changed internal pressure is naturally discharged through the air hole 240 and maintains equilibrium.

A hole is provided in one side portion or a part of the outer peripheral edge of the water supply pipe 210, and the suction port 252 of the aspirator 250 is connected through a connection pipe 254 as a connection medium.

In addition, a plurality of discharge ports 256 are formed on the lower side surface including the lower end of the aspirator 250 to discharge the sucked bad odor to the water tank 200. In particular, the discharge port 256 must always be immersed in water. .

The reason why this is possible is that, as described above, the upper end of the water supply pipe 210 protrudes from the bottom surface of the small water tank 200 to a certain height, so that water is always accumulated at the lower height. It is.

Further, in the operation of the aspirator 250, as an example for the operation, a temperature sensor for detecting a human body temperature, a proximity sensor for detecting the approach of a person, or a sensor for detecting a bad smell (for example, a specific odor) A kind of odor sensor that detects that the component that smells when it is above a certain level is installed, and on / off by the control of a control unit (not shown) using detection signals of these sensors It may be configured to operate.

As another example, a circuit may be designed to operate during a predetermined time after the floating ball 220 is closed even when the lever 310 is operated and the post-stool water flows. Of course. The confirmation that the floating ball is closed may be set so that the floating ball is closed when a preset time has passed after the other sensor or the floating ball is opened.

The present invention having such a configuration has the following operational relationship.

When the user sits on the toilet body 100 for the toilet and starts the toilet, the aspirator 250 operates. That is, the aspirator 250 is operated by the operation of one or more of the sensors and the control of the control unit.

Then, malodor is inhaled through the water supply port or the washing water hole 112 that is open around the inner wall surface of the toilet body 100, but the inhaled malodor is collected in the water supply pipe 210 and then into the connecting pipe 254. Along with the aspirator 250, the water is discharged into the stored water inside the small water tank 200 through the discharge port 256.

As a result, the malodor is released into the water in the form of bubbles, so that the surface area is large and most of it is dissolved instantaneously. However, the increased pressure generated in this process inside the small water tank 200 is the air hole. It is resolved via 240.

Next, when the stool is terminated and the lever 310 is pushed to flow the water, the water directly supplied from the water pipe flows into the small water tank 200 at the same time, and the floating ball 220 rises at the same time, and the water level of the water supply pipe 210 is increased. When the upper end is exceeded, the water supply pipe 210 is opened, but the water is rapidly discharged through the water supply pipe, and the excrement is discharged into the sewage tank by the discharged water.

In this process, if the water level becomes excessively high, the upper or upper end of the floating ball 220 that is raised closes the air hole 240 while being in contact with the ceiling surface of the small water tank 200, and the water is discharged via the air hole 240. Since it comes to be sealed so that it does not scatter to the outside, it can be used safely. In this case, water comes out more strongly through the water supply pipe.

And when flowing water, the drive of the aspirator 250 is in a state of being presented or operated. That is, the operation on / off is implemented according to information set in advance in a memory unit (not shown), the sensing information, or information of a user who is manually input as a defecate.

As described above, since the bad odor can be effectively and efficiently removed by inhalation by incorporating the small water tank 200 into the direct water type and implementing it in a hybrid form, it is expected to be very useful in terms of hygiene and health. Is done.

On the other hand, another preferred embodiment according to the present invention may be modified as shown in FIG.

Referring to FIG. 4, the floating ball 220 may be rotatably hinged through a separate bracket extended from the water supply pipe 210 as in the related art, or a hinge shaft is fixed to both inner walls of the small water tank 200. And may be configured to be rotatable.

In addition, a vent hole 230 penetrating vertically is formed at the end portion or the tip (the opposite end of the hinge shaft) of the floating ball 220.

The vent hole 230 is configured to close when the floating ball 220 receives a large amount of buoyancy and to open when the float 220 receives a small amount of buoyancy. For this purpose, a push valve CK1 is provided at the upper end of the vent hole 230. Installed.

Of course, a known valve CK2 may be further installed at the lower end of the vent hole 230 for operational stability, but preferably only the push-type valve CK1 may be installed.

At this time, as shown in FIG. 5, the push-type valve CK 1 includes a fixed base 400 that is fixed by being fitted into the upper end of the vent hole 230, and a flow hole 410 that is formed through the fixed base 400. , A flow rod 420 fitted into the flow hole 410, a sealing plate 430 fixed to the lower end of the flow rod 420, a cylindrical cap 440 detachably fixed to the fixed base 400, and the cap 440. An air outflow hole 450 formed by perforation in a part of the periphery, and an elastic spring 460 interposed between the inner bottom surface of the cap 440 and the lower surface of the sealing plate 430 are configured.

For the operation of the push-type valve CK1, the air hole 240 has a structure in which a contact plate P supported by a large number of ribs R is formed at the center of a circle as illustrated in FIG.

Therefore, the upper end of the flow rod 420 of the push-type valve CK1 is opened because it is pressed while being in contact with the contact plate P. At this time, the air supplied through the air hole 240 is the flow hole 410, the air It flows into the vent hole 230 through the outflow hole 450.

Therefore, when the floating ball 220 rises and comes into contact with the ceiling surface of the small water tank 200, more precisely, the contact plate P, the vent hole 230 is opened while being pushed. Since external air is introduced and air is supplied below the floating ball 220, the speed at which the floating ball 220 is closed correspondingly decreases. In other words, the floating ball 220 is delayed from closing.

This is because the lever 310 of the valve body 300 is closed too early or when the water pressure fluctuates, if the water pressure after the floating ball 220 rises from the water pressure at the time of the first water supply becomes lower, the floating ball Since 220 drops instantaneously and closes immediately, there is a possibility that the water supply may be interrupted before the excrement is completely discharged, and a phenomenon that the water is not sufficiently discharged occurs. In order to prevent this, for example, this case is considered when receiving a small amount of buoyancy, and the case where the floating ball 220 is strongly raised when supplying a minimum amount of water, for example, when receiving a large amount of buoyancy. To do.

If the valve CK2 is further installed, the valve CK2 is a valve that is opened only in the downward direction and is always closed in the reverse direction, so the vent hole 230 is an example of a water storage means. When it comes to coincide with the air hole 240 while being in contact with the ceiling surface of the water tank 200, external air is introduced while the push valve CK1 is opened, and when the contact state is released, the vent hole is formed by the spring elasticity of the push valve CK1 itself. In this case, the backflow of the air supplied into the small water tank 200 is prevented.

Of course, as described above, the push-type valve CK1 and the valve CK2 may not be provided in the vent hole 230. However, when these are further provided, if an unexpected accident occurs, for example, excessive water pressure is applied due to a failure of the valve body 300, In order to completely prevent the probability that water inside the small water tank 200 is ejected to the outside of the water tank through the air holes 230 and the air holes 240, it is more preferable to include them.

Such a structure is exemplary and can be modified in any number within the scope of the technical idea of the present invention.

On the other hand, as another modified example, as shown in FIG. 6, a floating ball 220 without a vent hole 230 is used, and the first hydraulic valve 500 is installed below the vent hole 240 of the small water tank 200 instead of the valve CK1 described above. The vent hole 240 may be configured so that the first hydraulic valve 500 directly opens and closes.

Here, the first water pressure valve 500 is integrally formed with a cylindrical fixed casing 510 fixed to the ceiling surface of the small water tank 200 and a lower end surface of the fixed casing 510. A cylindrical water storage housing 520 separated by a bottom plate 510 as a boundary, an open / close rod 530 installed through the bottom plate 510, an open / close plate 540 fixed to the upper end of the open / close rod 530 and opening / closing the air hole 240. The hydraulic pressure plate 550 is fixed to the lower end of the opening / closing rod 530 and disposed inside the water storage housing 520, and is connected through the bottom surface so as to communicate with the water storage housing 520, and the valve body 300 (FIG. 3) and a hydraulic pressure induction hose 560 that is opened and closed by the hydraulic plate 500 and is opened and closed between the hydraulic plate 550 and the bottom plate 520. Configured to include the value 570.

Therefore, when water is supplied from the valve body 300 by pushing the lever 310, a part of the water is moved along the water pressure induction hose 560 at that time, and the water pressure at that time is sufficient to push up the water pressure plate 550. Because of the pressure, the hydraulic plate 550 rises while compressing the open / close spring 570.

Then, while the opening / closing rod 530 is raised, the opening / closing plate 540 is brought into close contact with the ceiling surface of the small water tank 200 to close the air hole 240 and operates so as not to leak even if excessive water is supplied.

The method of fixing the fixed casing 510 to the ceiling surface of the small water tank 200 is not shown in detail, but as described above, the protrusion is provided on the ceiling surface and is screwed to the protrusion. However, since there are various methods such as fixing with another bracket, the method for fixing the water storage housing 520 to the fixed housing 510 is also the same.

Reference numeral “AH” that is not described is an air flow hole, and is a passage that eliminates the internal pressure of the small water tank 200 when the air hole 240 is opened.

Other configurations such as the aspirator 250 are as described above.

On the other hand, as shown in FIG. 7, the present invention may be modified to a system in which the water supply pipe 210 is directly opened and closed using the second hydraulic valve 600 without using the floating ball 220.

The second water pressure valve 600 penetrates one side of the outer peripheral surface of the lower end portion of the tubular body 610 and the tubular body 610 whose upper and lower surfaces are fixedly installed inside the small water tank 200 using a separate bracket. The water pressure generating hose 620 extended so as to be exposed to the inside of the valve pipe of the valve body 300 (see FIG. 3), and the tubular body 610 at a position higher than the point where the water pressure generating hose 620 is connected. An operation plate 630 installed inside the operation plate, an operation spring 640 interposed between the operation plate 630 and the ceiling surface of the tubular body 610, an operation rod 650 fixed to a lower end surface of the operation plate 630, and A water supply pipe opening / closing plate 660 that is fixed to the lower end of the operating rod 650 and opens and closes the water supply pipe 210 is configured.

Of course, in this case, it is preferable to use the first hydraulic valve 500 described above to open and close the air hole 240.

Then, when the lever 310 is pushed and water is supplied from the valve body 300, a part of the water is moved along the water pressure generating hose 620 at that time, and the water pressure at that time pushes up the operation plate 630. Since the pressure is sufficient, the moving plate 630 rises while compressing the operating spring 640.

Then, the water supply pipe opening / closing plate 660 is pushed up while the operating rod 650 is raised, so that the water supply pipe 210 is eventually opened. At this time, water is supplied through the water supply pipe 210 and the stool is discharged to the sewer tank. become able to.

On the other hand, when the lever 310 is released, water is not supplied, so that the water supply pipe 210 is eventually sealed by the water supply pipe opening / closing plate 660 by the elastic return force of the operating spring 640.

Further, it is effective that the malodor removing operation is performed in a state where the water supply pipe 210 is sealed.

A part of the outer peripheral edge of the water supply pipe 210 and the suction port 252 of the aspirator 250 are connected by a connecting pipe 254.

Thus, the direct water type malodor removing apparatus according to the present invention can be modified into various forms.

As shown in FIG.8 and FIG.9, the malodor removal apparatus of the 2-way type toilet bowl by this invention contains the water storage tank 105 which is an example of a water storage tank means.

In the water-saving toilet, the water storage tank 105 is a means for storing water to be used when supplying toilet water to a toilet main body made of pottery and discharging excrement inside the toilet main body into a sewer of the toilet bowl. .

In particular, the present invention is applied to a toilet having a dual structure in which washing water for washing the inside of a toilet main body and discharged water for discharging excrement are supplied through different paths.

That is, when the lever 110 is pushed, the flap 120 is opened, and the drainage water is rapidly drained into the toilet body through the discharge port (not shown) including the water supply pipe that the flap 120 has closed. It will be discharged into the sewage ditch of the toilet along with the discharge inside.

On the other hand, the wash water is different from the discharge water in that the level of the stored water is low because the flap 120 is opened, and the supply valve is opened to store water in the water storage tank, which is a water storage means. Although the amount flows to the washing water supply pipe 140, a number of washings formed around the inside of the toilet body through the washing water supply pipe 140 and, for example, the washing water communication chamber 150 provided in the water storage tank 105. By flowing through a water hole (not shown), the inner wall surface of the toilet body is washed.

In this way, the water-saving toilet has reduced the amount of wash water that was unnecessarily wasted by allowing the wash water to be supplied to the toilet body via a flow path different from the discharged water. Is.

Reference numeral “160” not described is an overflow pipe.

The present invention further includes an air intake / exhaust unit 205 as an example of an air intake / exhaust unit containing bad odor inside the water storage tank 105 as an example of the water storage unit in the toilet having such a structure, and is generated when the toilet is used. Immediate inhalation removal of bad odors prevents the bad odors from spreading inside the toilet and allows the user to sniff the bad odors from their toilets to a minimum.

For this purpose, in the present invention, the two-way distributor 215 is fitted and fixed to the end of the cleaning water supply pipe 140.

The two-way distributor 215 is a general direction change valve that branches the fluid supply direction in two directions, and is formed in a substantially “T” shape.

Then, one end is connected to the cleaning water communication chamber 150, and the multiple ends that form a straight line with the cleaning water communication chamber 150 are connected to the cleaning water supply pipe 140, and the branch pipe 255 formed between them is a connecting means. A suction pipe 235 (which corresponds to the connecting pipe 254 in FIG. 3) is connected.

The suction pipe 235 is connected to the suction end 180 of the air suction / discharge unit 205, and a discharge end 170 (FIG. 3) which is a discharge unit provided in the air suction / discharge unit 205 which is an example of the air suction / discharge unit. (Corresponding to the discharge port 256) is maintained in a state immersed in the discharge water stored in the water storage tank 105.

In addition, the air suction / discharge unit 205 is configured to be sucked and discharged by an aspirator, and the cleaning water supply pipe 140 is formed with a bellows in a part of the length for convenience of piping, so that the pipe can be easily bent. Composed.

If comprised in this way, unless the user pushes the lever 110 and it flows water, the said 2 way supply valve 130 will maintain the state always closed, and a sensor (not shown) and a control part (not shown) will be shown. The air intake / exhaust device 205 automatically senses the defecation state by operation, and sucks air, and the air sucked into the air intake / exhaust device 205 is exclusively connected to the washing water communication chamber 150. There are only washed water holes (many formed around the inner wall surface of the toilet body).

Therefore, when the air suction / discharger 205 is operated, malodor inside the toilet body is quickly sucked and dissolved while spreading into the water inside the water storage tank 105 via the discharge end 170 of the air suction / discharger 205. Odor is removed.

On the other hand, as another embodiment, the air intake / exhaust device 205 may be connected to the toilet body directly or through an intermediate medium without using the two-way distributor 215 to inhale air containing bad odor. In this case, the washing water supply pipe may also be connected to the washing water communication chamber directly or through another intermediate medium without going through the two-way distributor 210.

However, although it is a fact that technical progress has been achieved since the bad odor of a water-saving toilet can be quickly removed with such a simple structure, it is true that the air intake / exhaust device 205 is operated while being inhaled and discharged. Since pulsation occurs and flows along the pottery, which is the toilet bowl body, it is not easy because it causes a problem that causes noise of concern.

As a result of measurement for confirmation, there may be a difference depending on the size of the space, but at least 68 dB or more is measured, which corresponds to the noise of interest.

Therefore, the present applicant has continued to devise, and has come to solve this through a method of configuring the chamber so as to cancel out the pulsation, which is as follows.

In other words, the occurrence of pulsation itself cannot be eliminated because the air intake / exhaust device 205 is a kind of pump using a motor. The chamber 305 is connected and installed.

At this time, the buffer chamber 305 may be any of various shapes of sealing members having a larger space than the suction pipe 235, and in a state where a part of the length of the suction pipe 235 is analyzed, Is configured to be tightly connected to both ends of the buffer chamber 305.

Then, even when the air intake / exhaust device 205 is driven, a constant amount of fluid is always contained in the buffer chamber 305 having a space that is significantly larger than the pipe diameter of the suction pipe 235 (pipe diameter). In order to make the flow of air entering the toilet's washing port constant by buffering, pulsation due to the pressure difference between short sections where suction and discharge are repeated is offset inside the buffer chamber 305, and noise is reduced. The amount will be significantly reduced accordingly.

As a result of measuring with a noise measuring instrument with the buffer chamber 305 installed, it was found that when there was no buffer chamber 305, it was 68 dB, but the average was reduced to 59 dB. .

Therefore, the use of the present invention is expected to contribute to the creation of a comfortable and happy toilet culture because it can effectively inhale and remove bad odors in a very short time while reducing the noise. Is done.

Incidentally, the driving of the air suction / discharge device 205 can be controlled by utilizing a temperature sensor that senses the body temperature of a person or a proximity sensor that senses the approach of a person.

The present invention will be described with reference to FIGS. 2-9.
