Description

Deodorizing device for toilet

Technical Field

The present invention relates to a deodorizing device for a toilet, and more particularly, to an improved deodorizing device for an inline toilet, which can suck and remove offensive odor and bacteria generated when the inline toilet using the water pressure of tap water is used to relieve the hands, protect the human body from the bacteria, and create a comfortable environment in a toilet.

Background

In general, a toilet (referred to as a toilet bowl) is a western-style water closet of a sitting type in which a person sits astride and releases his or her hands, but the present invention is not limited thereto, and includes other types of toilets using water.

These toilets generally comprise: a toilet seat on which a user sits when relieving his or her hands; a toilet body for discharging excrement together with supply water to a septic tank; and a water tank disposed at an upper end of one side of the toilet body, supplying, storing and discharging the supplied water to discharge excrement to the septic tank.

Such a toilet stool has a structure in which feces and urine discharged from the excretory organs (intestinal Organ) of a user during release of hands are temporarily stored and discharged, so that it is reported that severe malodor is inevitably emitted during release of hands, and various Pathogenic Bacteria (Pathogenic Bacteria) such as salmonella, coliform Bacteria, shigella, clostridium and the like are easily propagated, and in particular, staphylococcus aureus, pseudomonas aeruginosa, streptococcus and the like are propagated at the parts in contact with the body.

However, these pathogenic bacteria may cause harm depending on the health condition of the user, and various skin diseases, respiratory diseases, and the like may be caused by these pathogenic bacteria, which are very unpleasant to use.

In connection with this, as a technique for removing offensive odors generated when hands are released, korean laid-open patent No. 2004-0103432, published patent No. 2010-0049464, published patent No. 2010-0106892, korean granted patent No. 0568252, korean granted utility model No. 0393220, and the like are disclosed.

However, most of the disclosed techniques employ a chemical, ultraviolet treatment, ultrasonic cleaning, or the like as means for deodorization, sterilization, disinfection, or antisepsis in order to remove offensive odors or pathogenic bacteria, and thus have disadvantages of complicated structure, increased manufacturing cost, and insignificant effects.

Therefore, most users operate the operation lever to discharge excrement with the toilet lid detached to prevent the spread of pathogenic bacteria to the entire toilet, which is attributed to various reports and media in which the spread of pathogens is reduced by more than 2 times when the toilet lid is attached, as compared with when the toilet lid is not attached.

However, since it is inconvenient to close the toilet lid each time, most users do not close the toilet lid so much because of the inconvenience and annoyance, and the act of closing the toilet lid needs to be performed consciously but easily forgotten, so that the act of closing the toilet lid itself is not easy in fact.

In order to improve such a situation, the present applicant filed a plurality of patents including granted patent No. 1502302, granted patent No. 1382693, and granted patent No. 1409515 based on the research results of many years.

On the other hand, the above-described toilet bowls all adopt a mode of flushing water stored in the tank to dispose of excrement in a state of having the tank, but this mode wastes much water, has a weak water pressure and occupies a large installation space, and therefore, unlike this mode, it is also widely used, and a direct discharge type toilet bowl in which a water pipe is directly connected without installing the tank and water can be supplied only when necessary is directly used.

For example, as shown in fig. 1, in the direct discharge type toilet, a water supply pipe 20 for supplying water to the toilet main body 100 is provided on the rear side of the toilet main body 100, the water supply pipe 20 is directly connected to a straight water pipe 40 as a water pipe via a valve body 300, and when the user releases his/her hand and presses an operation lever 32 provided on the valve body 300, water is supplied while the water pressure applied to the water pipe directly acts, and excrement is discharged.

As described above, this structure has the advantages of being simple, occupying no installation space, having a high water pressure, and thus having excellent discharge capability.

However, it is difficult to provide such an inline toilet with a device for deodorization.

Since, as for the water tank type toilet, a method of deodorization using a water tank has not been known, but the direct discharge type toilet has no water tank, so that a detachable type deodorization apparatus as presented in korean patent laid-open No. 1058923 or japanese laid-open patent No. 1996 and 277563 is also realized at most.

However, the detachable deodorization device is configured to be detachable from the toilet main body, which is inconvenient to sit on and has a poor appearance, and particularly, when a man stands for urine, the man may get splashed urine, which is a disadvantage of poor hygiene.

Recently, water saving toilet bowls have been disclosed according to government policies, which are designed to supply cleaning water for cleaning the inside of a ceramic toilet bowl body and excrement discharge water through different paths, thereby preventing waste of water.

That is, when the ordinary toilet is flushed, water contained in the tank is poured into the toilet main body, and a part of the water flows out through the plurality of cleaning water holes formed in the peripheral portion of the inner wall surface of the toilet main body at the same time, so that the excrement flows toward the toilet drain port, and the other part of the water cleans the inner wall surface of the toilet main body.

Therefore, in such a configuration, the tank is designed in consideration of clean water, and the shortage of water due to the growing waste of water is accelerated and worsened, and as a countermeasure for this, a water-saving toilet is disclosed.

However, in this configuration, the deodorization technique is actually weak as compared with the deodorization technique in the toilet bowl that has been developed in many common forms, and improvement of the current situation is required.

Detailed Description

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

First, when reference is made to a reference numeral for a member in each drawing, it should be noted that the same reference numeral is used as much as possible for the same member even if it is shown in different drawings. In describing the embodiments of the present invention, detailed descriptions of substantially the same contents will be omitted.

In addition, when a component is referred to as being "connected", or "coupled" to another component, the component may be directly connected or coupled to the other component, but the same technical idea should be understood when another component is "connected", or "coupled" between the components.

In addition, when a component is referred to as being designed, having, formed, or constituting, it should be construed as substantially the same unless specifically defined otherwise.

In addition, the term "comprising" in the present invention means that the structure or the component may include other components or constituents in addition to the above-mentioned structure or the component.

The expressions such as "upper end", "lower end" or "lower end" used in the description of the present invention are not only indicative of the end of the structure but also interpreted as a part of the structure (upper part, lower part, etc.), and are explained by the overall contents of the invention. That is, terms should be interpreted to mean not only end portions of the structure but also corresponding position portions of the structure.

In the description of the present invention, the float is one of the toilet water level adjusting means, and the technical idea of the present invention also includes a case where the float is replaced by another means.

As shown in fig. 2 and 3, the direct discharge type toilet deodorization device according to the preferred embodiment of the present invention includes a toilet main body 100.

The toilet main body 100 has a generally well-known structure, and is configured to store a predetermined amount of water therein, and discharge the remaining excrement into the lower tank when the user releases his/her hands.

In this case, the present invention includes a small-sized water tank 200 as an example of the water storage unit.

The small-sized sink 200 is significantly small in size, unlike the conventional sink, and is different from the conventional water tank in that direct water supply is used.

Therefore, it can be understood that there is almost no limitation in the installation space, and there is a way of the deodorization module sucking the offensive odor in the middle of the water flowing. In addition, since the air hole 240 is opened and closed by the operation of the float 220, which is an example of toilet water level adjusting means, in fig. 3, the water pressure of the tap water is used, and thus the present invention can be regarded as a direct discharge type using the water pressure of the tap water.

However, it is clear that the present invention is a new invention in that a part of the two devices is not simply combined but is improved to be able to use direct water supply, and the description will be made later.

That is, a valve body 300 is connected to one side surface of the small water tank 200 as an example of the water storage means, the valve body 300 is connected to a straight water pipe (water pipe) and is a means for controlling opening and closing of water, and an operation lever 310 as a means for inputting a user command is provided on the valve body 300. In the present invention, a push type or other device may be used instead of the operation lever, which is an example of a user instruction input unit for opening/closing (open/close) valves. The valve body is an example of a control unit for opening and closing the water, and therefore, other units may be used instead, and the scope of the claims is not limited to the above configuration.

Therefore, when the operation lever 310 is pressed, water is supplied by the water pressure of the straight water pipe, supplied into the small water tank 200, and discharged to the toilet main body through the water supply pipe. That is, the excrement is discharged by the water pressure, and thus the embodiment of the present invention also belongs to the inline type.

Meanwhile, a water supply pipe 210 penetrating the small water tank 200 is provided on one side, a lower portion, or a lower end surface of the small water tank 200, and an end portion (lower end) of one side, a lower portion, or a lower portion of the water supply pipe 210 is connected to the toilet main body 100.

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

Here, the predetermined height may be set to a level that allows the outlet 256 to be immersed in water.

This is a completely different concept from the conventional water tank type toilet stool, in which the bottom of the small water tank 200 is always filled with water of a predetermined height, but in the conventional water tank type toilet stool, water is not left at the bottom of the water tank and water pressure can be sufficiently obtained only by discharging all or substantially all of the water, and therefore, the upper end of the water supply pipe is installed in alignment with the bottom surface of the water tank. On the contrary, in the present invention, since water is discharged by the water pressure of tap water, the structure in the water tank is changed so that the inlet of the water supply pipe is positioned at a predetermined height so that water is left below the inlet, and the water can be used to dissolve offensive odor supplied through the discharge port 256 provided in the aspirator (asparator), which is an example of the air discharge and suction means, and the discharge port 256 is an example of the discharge means.

A float 220 for opening and closing the water supply pipe 210 is provided at an upper end of the water supply pipe 210.

In addition, an air hole 240 is formed on the top surface of the small-sized sink 200 to introduce external air to release internal pressure.

On the other hand, an Aspirator (Aspirator)250, which is an example of an air exhaust and suction means, is provided inside the small water tank 200.

The suction unit 250 is generally called a unit capable of sucking air, sucks offensive odor remaining in the toilet main body 100 through the water supply pipe 210, guides the offensive odor to the small water tank 200 through the connection pipe 254, which is an example of a connection unit, and the discharge ports 256, which are discharge units, and dissolves the offensive odor in water stored at a predetermined height in the bottom.

Therefore, the aspirator 250 is a unit for discharging a part of the inside air purified by dissolving the malodor to the outside through the air hole 240 in a purified state.

Therefore, the air hole 240 is a very important structure, the internal pressure of the small water tank 200 is changed by the operation of the aspirator 250 which is an air exhaust and suction unit (for example, if the internal pressure is increased, the mixed gas including the bad smell cannot be inhaled), and the changed internal pressure is naturally exhausted through the air hole 240, thereby maintaining the balance.

A hole is formed at one side portion or a portion of an outer circumferential edge of the water supply pipe 210, and the suction port 252 of the suction unit 250 is connected to a connection pipe 254 as a connection medium.

In addition, a plurality of discharge ports 256 are formed at a lower side surface including a lower end of the aspirator 250 to discharge the sucked malodor to the water tub 200, and particularly, the discharge ports 256 should be always immersed in water.

For the reason that this can be achieved, as described above, the upper end of the water supply pipe 210 is projected from the bottom surface of the small water tank 200 by a predetermined height, and therefore, the water tank is always filled with water below the predetermined height.

As an example of the operation of the aspirator 250, a temperature sensor for detecting the body temperature of a human body, a proximity sensor for detecting whether or not a person approaches, a sensor for detecting offensive odor (for example, an odor sensor for detecting odor which causes the aspirator 250 to operate when a component emitting a specific odor is equal to or more than a predetermined value) or the like is provided in a part of the toilet main body 100, and the aspirator 250 is operated or stopped by the control of a control unit (not shown) by using detection signals of these sensors.

As another example, it is also possible to configure the circuit so that the aspirator 250 continues to be operated for a predetermined time after the float 220 is closed when the operation lever 310 is operated to flush water after releasing the hand. The confirmation of whether the float is closed may be by other sensors or may be designed such that the float is closed after a predetermined time has elapsed since it was opened.

The present invention thus constituted has the following operational relationship.

When the user starts to relieve his/her hand by sitting on the toilet main body 100, the aspirator 250 starts to operate. That is, the aspirator 250 may operate based on the operation of one or more of the sensors and the control of the controller.

As described above, the bad odor is sucked through the water supply port or the cleaning water hole 112 formed by the perforation in the peripheral portion of the inner wall surface of the toilet main body 100, and the sucked bad odor is collected in the water supply pipe 210, and then discharged to the water stored in the small water tank 200 through the suction device 250 through the connection pipe 254 and the discharge port 256.

Thus, the bad odor is released into the water in the form of foam, and is mostly instantly dissolved due to the wide surface area, and the pressure increased in the interior of the small-sized sink 200 generated in the process is released through the air holes 240.

When the user releases his hand and presses the lever 310 to flush the water, the water directly supplied from the water pipe instantly flows into the small water tank 200, the float 220 rises, and when the water level exceeds the upper end of the water supply pipe 210, the water supply pipe 210 is opened, the water rapidly flows out through the water supply pipe, and the excrement is discharged into the lower water tank by the discharged water.

In this process, if the water level is too high, the upper portion or the upper end portion of the rising float 220 contacts the top surface of the small-sized water tank 200 to seal the air hole 240, so that water is not scattered to the outside through the air hole 240, and thus safe use can be achieved. In this case, the water flows more strongly through the water supply pipe.

Further, at the time of flushing, the driving of the aspirator 250 is in a stopped or operating state. That is, the operation or stop of the aspirator 250 is controlled based on information preset in a storage unit (not shown), the sensing information, or manually input information of a user, i.e., a person who defecates.

As described above, the small water tank 200 is also combined with the direct discharge toilet, and a mixing system is realized, whereby the offensive odor can be efficiently and effectively inhaled and removed, and it is expected that the direct discharge toilet is very useful in terms of hygiene and health.

On the other hand, as another preferred embodiment of the present invention, it may be modified as shown in fig. 4.

According to fig. 4, the float 220 may be rotatably hinged by a separate bracket extending from the water supply pipe 210, as in the conventional float, or may be rotatably hinged by fixing hinge shafts to both inner walls of the small water tank 200.

Furthermore, a vent hole 230 is formed at a distal end portion or a front end (an end opposite to the hinge shaft) of the float 220 to penetrate vertically.

The vent hole 230 is configured to be closed when the float 220 is subjected to a large buoyancy and to be opened when the float is subjected to a small buoyancy, and for this purpose, a push-type valve CK1 may be provided at an upper end of the vent hole 230.

Of course, for stability of operation, a known valve CK2 may be further provided at the lower end of the vent hole 230, and it is preferable that only the push valve CK1 be provided.

At this time, as shown in fig. 5, the push valve CK1 includes: a fixing substrate 400 fixed to the upper end of the vent hole 230; a flow hole 410 formed through the fixed substrate 400; a floating rod 420 inserted into the flow hole 410; a sealing plate 430 fixed to a lower end of the floating rod 420; a cap 440 having a cylindrical shape and detachably fixed to the fixed substrate 400; an air outflow hole 450 formed in a perforated manner on a portion of a peripheral portion of the cap 440; and a spring 460 disposed between an inner bottom surface of the cap 440 and a lower surface of the sealing plate 430.

In order to operate the push valve CK1, the air hole 240 has a contact plate P formed at the center of a circle, as in the example shown in fig. 4, and the contact plate P is supported by a plurality of ribs R.

Accordingly, the upper end of the floating rod 420 of the push valve CK1 is pressed to open by contacting the contact plate P, and at this time, the air supplied through the air hole 240 flows into the vent hole 230 through the flow hole 410 and the air outflow hole 450.

Accordingly, when the float 220 rises and opens the vent hole 230 while being pressed against the top surface of the small water tank 200, more precisely, the contact plate P, external air outside the small water tank 200 is introduced and air is supplied to the lower side of the float 220, and accordingly, the speed of closing the float 220 is reduced. In other words, the closing of the float 220 is delayed.

This is to prevent the occurrence of a phenomenon in which, when the operating lever 310 of the valve body 300 is closed too early or when the water pressure fluctuates, the float 220 is immediately closed by instantaneously lowering the float 220 when the water pressure after the rise of the float 220 is lower than the water pressure at the time of the initial water supply, and in this case, the water supply is interrupted before the excrement is completely discharged, which may cause an incomplete discharge. This case is referred to as, for example, receiving a small buoyancy, and the case where the float 220 rises strongly when water is initially supplied is referred to as, for example, receiving a large buoyancy.

Further, if the valve CK2 is provided, since the valve CK2 is a valve that opens only downward and is always closed in the reverse direction, when the vent hole 230 comes into contact with the top surface of the small water tank 200, which is an example of a water storage unit, and aligns with the air hole 240, the pusher valve CK1 opens to introduce outside air, and when the contact state is released, the vent hole 230 is closed by the self-spring elasticity of the pusher valve CK1, and at this time, the reverse flow of air supplied to the inside of the small water tank 200 is prevented.

Of course, even if the vent hole 230 does not have the push type valve CK1 and the valve CK2 as described above, it is preferable to further include these valves in order to perfectly prevent the possibility that water in the small water tank 200 is ejected to the outside of the water tank through the vent hole 230 and the air hole 240 when an unexpected accident occurs, for example, when an excessive water pressure is applied due to a failure of the valve body 300.

These configurations are illustrative, and any modification can be made within the scope of the technical idea of the present invention.

As another modification, as shown in fig. 6, a float 220 having no vent hole 230 may be used, and a first hydraulic valve 500 may be provided below the air hole 240 of the small water tank 200 instead of the valve CK1, and the first hydraulic valve 500 may directly open and close the air hole 240.

Here, the first hydrostatic valve 500 includes: a fixed case 510 having a cylindrical shape and fixed to the top surface of the small water tank 200; a water storage case 520 having a cylindrical shape and integrally extending from a lower end surface of the fixed case 510, and separated from the fixed case 510 by a bottom plate 512; an opening/closing lever 530 provided so as to penetrate the bottom plate 512; an opening/closing plate 540 fixed to an upper end of the opening/closing lever 530 for opening and closing the air hole 240; a water pressure plate 550 fixed to a lower end of the opening/closing rod 530 and disposed inside the water storage case 520; a water pressure guide hose 560 connected to the water storage case 520 so as to penetrate through the bottom surface of the water storage case 520, communicating with the water storage case 520, extending into and exposed from the valve tube of the valve body 300 (see fig. 3), and opened and closed by the water pressure plate 550; and an opening/closing spring 570 provided between the water pressure plate 550 and the bottom plate 512.

Therefore, when the pressing lever 310 is supplied with water from the valve body 300, a part of the water moves through the water pressure guide hose 560 at this time, and the water pressure at this time is a pressure sufficient to push the water pressure plate 550 upward, so the water pressure plate 550 rises while compressing the opening/closing spring 570.

Then, the opening/closing lever 530 is lifted up, and the opening/closing plate 540 is brought into close contact with the top surface of the small water tank 200 to close the air hole 240, thereby preventing water leakage when the amount of supplied water is excessive.

Although the fixing case 510 is not specifically illustrated as being fixed to the top surface of the small sink 200, various methods may be employed such as forming a protrusion on the top surface and fastening the protrusion with a screw, or fixing the protrusion with a separate bracket, as described above, and the water storage case 520 is not particularly limited to this and may be fixed to the fixing case 510.

Also, unexplained reference numeral 'AH' is an air flow hole, and is a passage for releasing the internal pressure of the small-sized sink 200 when the air hole 240 is opened.

In addition, other structures 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 mode in which the water supply pipe 210 is directly opened and closed by the second hydraulic valve 600 without using the float 220.

The second hydraulic valve 600 includes: a tubular body 610 fixed inside the small water tank 200 by a separate bracket, and having an upper surface and a lower surface sealed; a water pressure generating hose 620 connected to penetrate through the outer peripheral surface of the lower end of the tubular body 610 and extending and exposing into the valve tube of the valve body 300 (see fig. 3); a movable plate 630 provided inside the tubular body 610, the tubular body 610 being located at a position higher than the position to which the water pressure generating hose 620 is connected; a movable spring 640 disposed between the movable plate 630 and the top surface of the tubular body 610; movable rod 650 fixed to a lower end surface of movable plate 630; and a water supply pipe opening and closing plate 660 fixed to a lower end of the movable rod 650 to open and close the water supply pipe 210.

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

As a result, when water is supplied from valve body 300 by pressing operation lever 310, a part of the water moves through water pressure generation tube 620, and the water pressure at this time is a pressure sufficient to push movable plate 630 upward, so movable plate 630 rises while compressing movable spring 640.

Then, since the water supply pipe opening/closing plate 660 is lifted up while the movable rod 650 is lifted up, the water supply pipe 210 is finally opened, and at this time, water is supplied through the water supply pipe 210, and excrement and urine can be discharged into the lower water tank.

On the contrary, when the operation lever 310 is released, the water supply is cut off, so that the water pressure is lowered, and finally the water supply pipe 210 is sealed by the water supply pipe opening and closing plate 660 by the elastic restoring force of the movable spring 640.

Also, the deodorizing operation is effectively performed in a state where the water supply pipe 210 is sealed.

A part of the outer circumferential surface of the water supply pipe 210 is connected to the suction port 252 of the aspirator 250 through a connection pipe 254.

Thus, the direct discharge type deodorizing device of the present invention can be modified in various ways.

As shown in fig. 8 and 9, the two-way toilet deodorization device according to the present invention includes a tank 105 as an example of a water storage unit.

The tank 105 is a storage means for supplying water to a ceramic toilet main body of a water-saving toilet to discharge excrement in the toilet main body to a toilet drain port.

In particular, the present invention is applied to a toilet having a double flow path structure, and washing water for washing the inside of a toilet main body and drain water for discharging excrement are supplied through different flow paths.

That is, when the operation lever 110 is pulled, the flap 120 is opened, and the discharged water is rapidly discharged into the toilet main body through a discharge port (not shown) having a water supply pipe that is originally closed by the flap 120, and flows down to the toilet drain port together with the excrement in the toilet main body.

On the other hand, the cover 120 is opened, the water level of the stored water is lowered, the supply valve is opened to fill the water tank serving as the water storage unit with water, a predetermined amount of water flows into the wash water supply pipe 140, and wash water passes through the wash water supply pipe 140, passes through the wash water communication chamber 150 provided in the tank 105, and flows down from a plurality of wash water holes (not shown) formed in the peripheral portion of the toilet main body, for example, to wash the inner wall surface of the toilet main body.

In this way, the water-saving toilet supplies the washing water to the toilet main body through a flow path different from the discharge water, thereby reducing the amount of washing water which is originally innocently wasted.

Also, unexplained reference numeral '160' is an overflow pipe.

In the toilet stool having such a structure, the air ejector 205 is further provided in the water tank 105, which is an example of a water storage unit, and is an example of an air ejector for sucking offensive odor, so that offensive odor generated when the toilet stool is used can be quickly sucked, the offensive odor is prevented from being emitted into the toilet, and the offensive odor emitted when the user gets out of his hands can be minimized.

For this, in the present invention, the bidirectional distributor 215 is fastened to the end of the washing water supply pipe 140.

The bidirectional distributor 215 is a general direction change valve that divides a supply direction of fluid into two directions, and is formed in a substantially 'T' shape.

Accordingly, one end of the bidirectional distributor 215 is connected to the washing water communication chamber 150, the other end thereof is connected to the washing water supply pipe 140, and the branch pipe 225 formed therebetween is connected to the suction pipe 235 (which corresponds to the connection pipe 254 of fig. 3) as a connection unit.

The suction pipe 235 is connected to the suction end 180 of the air ejector 205, and is provided at the discharge end 170 (corresponding to the discharge port 256 in fig. 3) which is a discharge unit of the air ejector 205 as an example of the air ejector unit, and is maintained in a state of being immersed in the discharge water stored in the water tank 105.

Meanwhile, the air ejector 205 is configured to suck and discharge air by an ejector, and a bellows is formed in a part of the length of the cleaning water supply pipe 140 for the convenience of piping, so that the pipe can be easily bent.

With this configuration, the bidirectional supply valve 130 is always kept closed unless the user presses the operation lever 110 to flush, the air ejector 205 automatically detects the operation in the toilet bowl state by the operation of a sensor (not shown) and a control unit (not shown), and when air is sucked, the air sucked into the air ejector 205 is only sucked into the wash water holes (a plurality of holes are formed in the inner wall surface of the toilet bowl main body) connected to the wash water communication chamber 150.

Therefore, when the air ejector 205 is operated, the bad odor in the toilet main body is rapidly sucked, diffused into the water in the water tank 105 through the discharge end 170 of the air ejector 205, and dissolved, thereby removing the bad odor.

On the other hand, as another embodiment, the air ejector 205 is connected to the toilet main body directly or via an intermediate medium without passing through the bidirectional distributor 215, and can also suck air including bad odor. In this case, the washing water supply pipe may be connected to the washing water communication chamber directly or through another intermediate medium without passing through the bidirectional distributor 215.

Although the odor of the water-saving toilet can be rapidly removed by such a simple structure, the technical progress has been achieved, but the noise problem is not easy because the air suction/discharge device 205 generates a slight shock by suction and discharge when operating, and the slight shock causes a noise of an intentional level by being transmitted through the ceramic as the toilet main body.

The measurement was performed to confirm the noise, and as a result, there may be a difference depending on the size of the space, but the noise was measured to at least 68dB or more, which is an intentional level.

To this end, as a result of several considerations by the applicant, the problem is solved by providing a chamber to counteract the microseisms, as follows.

That is, the reason why the micro-shock is generated is that the air ejector 205 is a pump using a motor, which is an illegal case, and thus the applicant of the present invention provides the buffer chamber 305 in the middle of the length of the connection unit, i.e., the suction pipe 235.

In this case, the buffer chamber 305 may be formed of a sealing member having a plurality of shapes having a spatial area larger than that of the suction pipe 235, and the buffer chamber 305 is closely connected to both ends of the buffer chamber 305 after a part of the length of the suction pipe 235 is cut.

Thus, even if the air ejector 205 is driven, a predetermined amount of fluid is always contained in the buffer chamber 305 having a space relatively significantly larger than the pipe diameter (pipe diameter) of the suction pipe 235, and the flow of air entering the toilet bowl flushing port is made constant by the buffer action at the time of suction, so that the slight shock caused by the pressure difference due to repeated suction and discharge in a short time is cancelled out inside the buffer chamber 305, and the noise is significantly reduced.

In order to confirm this effect, it was confirmed that the noise of 68dB was reduced to 59dB on average without the buffer chamber 305, as a result of measurement with a noise detector in a state where the buffer chamber 305 was provided.

Thus, according to the present invention, it is possible to reduce noise, efficiently suck and remove offensive odor in a water-saving toilet in a very short time, and contribute to the creation of comfortable and happy toilet culture.

In addition, the driving of the air ejector 205 can be controlled by a temperature sensor that detects the body temperature of a person or a proximity sensor that detects whether or not a person approaches.
