Abstract

A flush toilet flushing structure comprises a bowl portion (11), a first waste removal channel (12), and a second waste removal channel (16). A first waste removal channel ascending segment (121), a second waste removal channel ascending segment (162), and the bowl portion are configured to form a water trap portion. The first waste removal channel does not comprise a structure that blocks the first waste removal channel when waste is removed through the second waste removal channel (16). When the second waste removal channel (16) is used to remove waste, a pump unit (212) and a pressure adjustment mechanism are employed to enable a highest point of the second waste removal channel (16) to be less than a highest point of the first waste removal channel. The second waste removal channel is configured to be a movable structure that can be moved in four ways, including being moved below a water seal level, thereby realizing removal of waste from the second waste removal channel (16). The disclosed technical scheme can be adopted to reduce water use per flush.

Description

Toilet flushing structure

Technical field

The invention relates to a water-washing toilet flushing structure, in particular to a water-saving double or double-position toilet flushing structure.

Background technique

Excessive water use is likely to cause a lack of urban water resources, increase the load on urban sewage pipelines, and increase the demand for urban sewage treatment capacity. Because of the high frequency of use, toilets account for a large part of the city's water consumption.

When there is a stool, there are many solids in the dirt. In order to avoid blockage of the building pipe, it is necessary to consider not only the sewage is discharged from the toilet but also a certain distance. When urinating, the dirt is a liquid, and there is no dirt adhering to the basin, and the toilet only needs to discharge the liquid dirt out of the toilet.

For the purpose of different discharges of different wastes, the current toilets are divided into two large and small punches. According to the difficulty of flushing out the dirt, the different water volumes are controlled to make the dirt pass through the same sewage pipe. The dirt is discharged.

In the study of differentiated sewage discharge, some patents proposed to separate urine and stool, but this product does not have a water seal that seals water, and does not meet the hygiene requirements of modern households.

In the study of differential sewage discharge, some patents proposed that the urination should be discharged by using a curved tube, and the stool should be directly discharged. The stool drainage channel does not have an ascending section relative to the basin, and only relies on a large area of rubber to block the stool drainage channel. Thereby forming a water accumulation structure, which in turn constitutes a water seal. When the above method clamps foreign matter on the sealing surface or the seal is not secure, the water seal disappears, the room returns to the smell, and even the small insect crawls out, so that a stable water seal cannot be provided from the structure, and there is a safety hazard.

In the study of differential sewage discharge, some literatures propose to use different sewage pipes to discharge large and small pipes. At the same time, large and small sewage pipes can be blocked by water, achieving good insect and odor prevention purposes. However, in order to avoid leakage of the large flushing pipe during urination, the large flushing pipe is blocked. In industrial practice, the valve used for blocking may be accidentally stuck in the hair, fish bones, paper towels, etc. of the toilet, resulting in The stool drain channel is blocked and the toilet will not be used.

There are also patents that use two different elbows to drain dirt and have two water trapping locations that require the user to drain the stool or urinate each drain port. In the case where this user's habit is changed, if the position of the user's excretion is wrong, the sewage pipe may be blocked and then cannot be used.

In this way, under the premise of meeting the hygiene requirements, not changing the user's habits, providing a stable sealing structure and durable structure, the inventors have studied the structure of the toilet and the method of discharging the dirt, in view of the characteristics of easy discharge. To achieve the purpose of saving water.

Summary of the invention

The purpose of this study is to provide a toilet flushing structure that has the following characteristics: saving the water consumption of the urinal without changing the user's excretion habits, and having two channels for separately discharging stool and urination, and there is no use due to use. The urinal passage leads to a structure in which the sewage drain passage is blocked, and the prior art toilet flushing method can still be implemented when the urinal sewage passage for water saving purposes is damaged. The two dirt discharge passages have a toilet when the toilet is not in use. The rising section thus has a stable water seal.

Based on the above features, the first toilet flushing structure provided by the present application comprises: a basin portion having a receiving surface for temporarily receiving dirt; and a first sewage channel connected to the lower portion of the basin portion, having a rising portion, The sewage channel does not have a structure for blocking the first sewage channel when the second sewage channel is used for sewage discharge; the second sewage channel has a rising portion, and the second sewage channel rising portion and the basin portion when the toilet is not in use The rising portion of the first sewage passage together forms a water accumulation portion which stores water when the toilet is not in use to form water, and the water seal is formed by the accumulated water, and the second sewage passage is connected to the water storage portion below the water cover. : It is characterized by:

The pump unit drives the water of the bowl to flow to the toilet drain through the second drain passage.

The first type of flush toilet has a basin for receiving dirt. Both the first sewage channel and the second sewage channel have an ascending section and together with the basin form a stable water accumulation structure. When the second sewage channel is used for sewage discharge, the first sewage channel does not have a blocking mechanism for blocking the first sewage channel, which greatly reduces the risk of the first sewage channel being blocked. The second sewage channel is used to save water when the urine is discharged, when the row When the object is only for urination, the pumping unit drives the urination in the basin to pass through the second sewage channel to the toilet drain. Therefore, it is ensured that the urine can be discharged without cleaning the water.

Preferably, the highest point of the second sewage channel is higher than the highest point of the first sewage channel. In this way, when the first sewage channel is used for sewage discharge, the highest point is compared with the lower first channel, and the first sewage is preferentially discharged to generate siphon, and the dirt of the basin is discharged to avoid the simultaneous discharge of the first sewage channel and the second sewage channel, resulting in the second The drain channel is prone to blockage and the flushing performance of the toilet is reduced.

Preferably, the second sewage channel has a section changing unit that can change the sectional area of the second sewage channel. When the first sewage channel is used for sewage discharge, the section change unit makes the section of the second sewage channel smaller or even the second sewage channel is cut off, and more accumulated water and washing water flow from the first sewage channel to the sewage outlet, avoiding the cause The second sewage channel and the second sewage channel simultaneously discharge the sewage, which causes the second sewage channel to be easily blocked and the flushing performance of the toilet to be reduced.

In summary, the first toilet flushing structure uses the pump unit to drive the pelvic water containing dirt through the second drain passage when the second drain passage is used for urination discharge. When the first sewage channel is used for the toilet discharge, the second sewage channel is used to lower the first sewage channel and reduce the second sewage channel to reduce the flow of dirt from the second sewage channel.

The second toilet flushing structure provided by the present application comprises: a basin portion having a receiving surface for temporarily receiving dirt; a first sewage channel connected to the lower portion of the basin portion, having an ascending section, and a first sewage channel There is no structure for blocking the first sewage channel when the second sewage channel is used for sewage discharge; the second sewage channel has a rising portion, and the rising portion of the second sewage channel and the basin portion and the first sewage channel when the toilet is not in use The ascending sections collectively form a water accumulation portion that stores water when the toilet is not in use to form a stagnant water, and the water trap forms a water seal, and the second drain passage communicates with the water accumulating portion below the water cover; The utility model has a variable pressure mechanism for reducing the air of the air column segment in the second sewage channel; the second sewage channel is connected to the water inlet portion or the second sewage channel inlet of the rising portion of the first sewage channel is higher than the continuous direction a sewage outlet or a sewage outlet of the second sewage outlet of the toilet sewage outlet; and the second sewage outlet further has: a gas suppression unit connected to the non-rising section of the second sewage channel, and located at Bowl portion below the level of said water seal, inhibiting gas enters the second suppressing unit trapway passage from the second sewage outfall; column section by the gas discharge passage between the second suppressing unit configured and water bowl portion.

The second type of flush toilet has a basin for receiving dirt. Both the first sewage channel and the second sewage channel have an ascending section and together with the basin form a stable water accumulation structure. When the second sewage channel is used for sewage discharge, the first sewage channel does not have a blocking mechanism for blocking the first sewage channel, which greatly reduces the risk of the first sewage channel being blocked.

The second sewage channel is used for water saving when the urine is discharged. When the discharge is only urinating, the pressure changing mechanism reduces the air in the air column in the second sewage channel, and at the same time, even if a small amount of gas passes through the gas suppression unit. The sewage from the sewage outlet of the second sewage channel enters the second sewage channel, and does not affect the partial pressure of the pipeline at the junction of the second sewage channel and the variable pressure mechanism. Under the partial negative pressure, the water in the basin is close to the negative pressure position. The water surface rises and flows out of the rising section of the second sewage channel to achieve the purpose of sewage disposal.

Further, the variable pressure mechanism includes a variable volume unit, and when the volume of the variable volume unit becomes larger, the internal pressure becomes smaller, and the air of the air column section can be sucked.

Optionally, the variable pressure mechanism includes a pump unit that draws air out of the gas column section by operation of the pump unit.

Further, the gas suppressing unit is constituted by the second water collecting portion of the second drain passage, and the water accumulated in the second water collecting portion isolates the air on the outer drain port side from the downstream side of the second water collecting portion.

When the second sewage channel is used for sewage discharge, driving the pump unit or increasing the volume of the variable volume unit can reduce the air in the gas column section and flow to the outside or the variable volume unit, causing the water on both ends of the air column to move up to the gas. The column section disappears. At this time, the water surface height near the sewage outlet of the toilet is lower than the height of the basin water. The siphon is generated under the action of gravity, and the water in the toilet flows to the basin through the second water accumulation portion, so that the liquid dirt is discharged. . Keeping the air out of the second drain channel allows the siphon to continue until the dirt is completely drained.

Optionally, the gas suppression unit has a cross-section changing unit that can change a partial cross-sectional area of the second passage. When it is required to inhibit air from entering the second sewage passage from the sewage outlet, the cross-section changing unit makes the cross-sectional area of the second sewage passage smaller. Thus, the rate at which gas is admitted is suppressed or even the second sewage passage is made smaller or closed.

When the second sewage channel is used for sewage discharge, the section changing unit that drives the air suppression unit makes the partial section of the second sewage channel smaller or even cut off, drives the pump unit or enlarges the volume of the variable volume unit, and the air flow direction in the air column section External or variable volume unit due to the second row The partial section of the sewage passage becomes smaller, and the air entering the second sewage passage is also less, so the negative pressure is generated in the air column section, and the water surface on the rising section of the second sewage passage moves from the rising section to the sewage outlet of the second sewage channel. Then, the flow cross section of the cross-section changing unit is covered to further improve the ability to suppress the incoming gas. As the gas is continuously exhausted from the gas column section, the gas suppression capability is continuously increased until the air in the air column section in the second sewage passage disappears, and the water level on the side close to the toilet drain port is lower than the height of the basin water. When it is ensured that the air in the second sewage passage is not allowed to enter, the pump unit or the varactor unit is stopped, and the negative pressure acting on the cross-section changing unit disappears, and the cross-section changing unit can also be driven to make the passage of the second sewage passage The area becomes larger. Both ends of the second sewage channel are siphoned under the action of gravity, and the dirt is discharged. Keeping the air out of the second drain channel allows the siphon to continue until the dirt is completely drained.

Optionally, the gas suppression unit is composed of a minimum passage section pipeline of the discharge section, and the flow cross-sectional area is not larger than an area of 30 mm in diameter; wherein the second sewage outlet and the second sewage passage are connected with the variable pressure mechanism. The passage at the junction is the discharge section. It is preferred to use a circular flow cross-sectional area having a diameter of 10 mm.

When the second sewage channel is used for sewage discharge, the pump unit is driven to extract the air in the gas column section, and the air in the vacuum gas column section flows to the outside, and the second sewage channel is connected to the sewage discharge channel of the building, and the variable pressure unit is connected. Under partial negative pressure, a part of the air enters the second sewage channel and is discharged by the pump. A part of the basin water rises into the sewage channel under the action of negative pressure. Since gas continuously enters from the minimum channel, the water flow cannot flow out, resulting in accumulation in the water. The water surface of the rising section of the discharge section and the second sewage passage is continuously raised until the gas in the second sewage outlet passage is evacuated, and only the gas sucked from the sewage outlet of the second sewage outlet is stopped, and the pump unit is stopped at this time, so as to ensure that the first When the air enters the second sewage channel, the pump unit or the varactor unit is stopped, the negative pressure acting on the minimum channel section pipeline disappears, and the accumulated water begins to flow to the sewage outlet of the second sewage channel, and the two ends of the second sewage channel Siphoning occurs under the action of gravity, and the dirt is discharged. Keeping the air out of the second drain channel allows the siphon to continue until the dirt is completely drained.

In this process, if the area of the minimum passage section is increased, the velocity of the gas flowing into the second sewage passage from the sewage outlet of the second sewage outlet is fast, and the pump unit is required to have a stronger gas discharge capacity. If the area of the minimum channel section is too small, it will be easily blocked by impurities from the basin. Under the balance of the pump unit and the risk of clogging, it is recommended that the cross-sectional area of the minimum passage section pipeline is not larger than the area of a circle of 30 mm in diameter, preferably using a circle having a section diameter of 10 mm and increasing the passage of foreign matter in the second drain passage inlet 161. The structure can reduce the risk of clogging and the pump unit's venting capacity will not increase significantly.

Preferably, the variable pressure mechanism is further capable of adding gas to the gas column section in the second sewage channel when the first sewage channel is used for sewage discharge. In this way, the water surface distance between the two ends of the gas column section becomes difficult to communicate, and the dirt cannot be discharged through the second sewage channel, thereby avoiding the simultaneous discharge of the first sewage channel and the second sewage channel, thereby causing the second sewage channel to be easily blocked and the flushing performance of the toilet. reduce.

In summary, the second toilet flushing structure drives the pump unit or the variable volume unit to perform air suction when the second sewage drain passage is used for urination discharge, and passes through the second water accumulation portion of the second sewage pipeline, the cross-section unit, and The small discharge section suppresses the air entering from the sewage outlet of the second sewage channel, thereby achieving the purpose of reducing the air of the gas column section, thereby causing the sewage to flow out of the basin, thereby exciting the siphon phenomenon and causing the dirt to pass through the second sewage. The channel is discharged. When the first sewage channel is used for the discharge of the urine and the urine, the second sewage channel is higher than the first sewage channel, the cross-sectional area of the second sewage channel is reduced, and the air of the gas column is increased, and the three methods are used to suppress the flow of the sewage from the second sewage channel. .

The third toilet flushing structure provided by the present application comprises: a basin portion having a receiving surface for temporarily receiving dirt; a first sewage channel connected to the lower portion of the basin portion, having an ascending section and a first sewage channel There is no structure for blocking the first sewage channel when the second sewage channel is used for sewage discharge; the second sewage channel has a rising portion, and the rising portion of the second sewage channel and the basin portion and the first sewage when the toilet is not in use The rising portion of the channel together forms a water accumulation portion that stores water when the toilet is not in use to form a water accumulation, the water seal is formed by the accumulated water, and the second sewage passage is connected to the water accumulation portion below the water cover; The second sewage channel is thinner than the first sewage channel, and the second sewage channel is The highest point is lower than the highest point of the first sewage channel: the second sewage channel is connected to the water inlet portion or the second sewage channel inlet of the first sewage channel rising portion is higher than the first sewage channel or the toilet sewage The sewage outlet of the second sewage channel of the mouth.

The third type of flush toilet has a basin for receiving dirt. Both the first sewage channel and the second sewage channel have an ascending section and together with the basin form a stable water accumulation structure. When the second sewage channel is used for sewage discharge, the first sewage channel does not have a blocking mechanism for blocking the first sewage channel, which greatly reduces the risk of the first sewage channel being blocked.

Under the same flushing situation, according to the prior art, it can be known that under the same water supply condition, the pipe with low sewage channel preferentially produces siphon, and the sewage channel has fine priority to generate siphon, so the highest point of setting the second sewage channel is lower than the highest point of the first sewage channel. And the inner diameter of the second sewage passage is thinner than the inner diameter of the first sewage passage.

In summary, when the third toilet flushing structure uses the second sewage channel for urination discharge, a thinner second sewage channel is provided and the highest point is lower than the highest point of the first sewage channel, thereby reducing the siphon of the second sewage channel. The amount of water consumed is stimulated so that the second pipe can discharge the urine of the urine with less water consumption. When the first sewage channel is used for the discharge of the urine, the method of lowering the sectional area of the second sewage channel is used to suppress the outflow of the dirt from the second sewage channel.

The fourth toilet flushing structure provided by the present application comprises: a basin portion having a receiving surface for temporarily receiving dirt; a first sewage channel connected to the lower portion of the basin portion, having an ascending section, and a first sewage channel There is no structure for blocking the first sewage channel when the second sewage channel is used for sewage discharge; the second sewage channel has a rising portion, and the rising portion of the second sewage channel and the basin portion and the first sewage when the toilet is not in use The rising portion of the channel together forms a water accumulation portion that stores water when the toilet is not in use to form a water accumulation, the water seal is formed by the accumulated water, and the second sewage passage is connected to the water accumulation portion below the water cover; The second sewage channel is a movable structure, and can move to below the water cover when the toilet is not in use, and the second sewage channel is connected to the water collecting portion or the rising portion of the first sewage channel is higher than the first sewage. The sewage outlet of the second sewage passage of the passage or the toilet sewage outlet.

The fourth type of flush toilet has a basin for receiving dirt. Both the first sewage channel and the second sewage channel have an ascending section and together with the basin form a stable water accumulation structure. When the second sewage channel is used for sewage discharge, the first sewage channel does not have a blocking mechanism for blocking the first sewage channel, which greatly reduces the risk of the first sewage channel being blocked.

Preferably, the highest point of the second sewage channel is higher than the highest point of the first sewage channel. In this way, when the first sewage channel is used for sewage discharge, the first channel with the relatively low highest point preferentially emits siphon, and the dirt of the basin is discharged, thereby avoiding the simultaneous discharge of the first sewage channel and the second sewage channel, resulting in the second The drain channel is prone to blockage and the flushing performance of the toilet is reduced.

In summary, the second toilet flushing structure drives the second drain passage below the water cover when the second drain passage is used for urination discharge, thereby exciting the siphon in the second drain passage to discharge the dirt through the second drain passage. When the first sewage passage is used for the discharge of the urine, the method of using the second sewage passage higher than the first sewage passage suppresses the flow of the dirt from the second sewage passage.

In the various methods of the present invention, under the premise that the product has a stable water-storing structure, the second sewage channel is used to discharge the urine, thereby achieving the purpose of urination sewage and water conservation: adopting the first without any blocking structure The sewage channel can reduce the risk of blockage of the first sewage channel; the method of working independently with two pipes can achieve the purpose of large and small flushing even if the second sewage channel for water saving is blocked. The method of a water seal achieves the purpose of not changing the customer's habits: and optimizes the flow reduction or blocking of the second sewage channel when the first sewage channel is discharged, so as to maintain the sewage performance of the first sewage channel is not affected. the goal of.

It is to be understood that the data so used may be interchanged where appropriate, so that the embodiments of the invention described herein can be implemented in a sequence other than those illustrated or described herein. Moreover, the terms "comprising" and "having" and "the" are intended

For convenience of explanation, the directions of the drawings in the specification are defined as follows: the user is seated on the toilet, and all the cross-sectional views are viewed from the left hand of the user to the toilet, and are cut away from the center of the toilet.

Description of the existing toilet flushing structure; as shown in FIG. 1 is a conventional toilet flushing structure, which has a bowl portion 11 and a first drain passage 12 having a channel that is small and including a first drain passage rising portion 121, and is cleaned. Water supply port 13, upper flushing portion 14, lower flushing portion 15, and toilet drain port 17.

The bowl portion 11 is used for receiving the dirt, the first sewage channel 12 is connected below the bowl portion 11 for discharging the urine and the urine, and the first sewage channel rising portion 121 and the bowl portion 11 together form a water collecting structure to be in the toilet. In order to form a sealed water when the water is not in use, the toilet further has a washing water supply port 13 connected to the washing water, a washing water supply port 13 and an upper supply portion formed by a plurality of small holes distributed in the circumferential direction of the inner edge of the bowl portion. At least one of the lower supply portions 15 formed by 14 and at least one of the nozzles provides washing water for the bowl portion 11, and the toilet drain port 17 is for discharging the washing water to the building pipe.

First toilet flushing structure

Comparing the existing toilet flushing structure and FIG. 1 with reference to FIG. 2, the first toilet flushing structure has the same pot portion 11 as the conventional toilet flushing structure shown in FIG. 1, and the first drain passage including the first drain passage rising section 121. 12. The washing water supply port 13, the upper flushing portion 14, the lower flushing portion 15, and the toilet drain port 17. further having: a second drain passage 16 capable of discharging sewage, wherein the second drain passage 16 has; at the bottom of the bowl portion 11 or The first sewage channel rising section 121 or the second sewage channel inlet 161 in the lower water outlet portion 15, the second sewage channel rising section 162, the second sewage channel sewage outlet 164, connecting the second sewage channel rising section 162 and the second sewage channel The connecting pipe 163 of the sewage outlet 164 is capable of driving the basin water to flow out of the pump unit 212 flowing out through the second sewage channel, and the second sewage channel is thinner than the first sewage channel. Preferably, the pump unit is a diaphragm pump that is not prone to blockage.

When not in use, the basin portion 11, the second sewage channel rising portion 162, and the first sewage channel rising portion 121 together form a water storage portion to store the washing water entering from the washing water supply port, thereby achieving the purpose of forming a water seal. As shown in Figure 2, the toilet water surface PL, the realization of the construction of the pipeline smell and pest control.

When the user performs urination, when the second sewage channel is used for sewage discharge, the pumping unit 212 is opened, and the liquid containing the urination and the accumulated water in the basin portion is sequentially passed through the second sewage outlet inlet 161 and the second sewage passage rising portion 162. The connecting pipe 163, the second sewage channel sewage outlet 164 flows to the toilet sewage outlet 17.

When the user performs the stool or urinate, when the first sewage channel is used for the sewage discharge, the washing water supply port 13 passes through at least one of the upper flushing portion 14 or the lower flushing portion 15 to the bowl portion 11, the bowl portion in FIG. The water surface PL rises, and dirt may be discharged in the second sewage channel 16 and the first sewage channel 12, thereby achieving the purpose of sewage discharge.

After the draining is completed, the washing water supply port 13 supplies water to the bowl portion 11, and the basin water surface PL rises to a predetermined value, and a water seal is formed again.

Further, in order to improve the performance when the first sewage channel 12 is discharged, the interference between the two sewage channels is avoided, and when the first sewage channel is used for discharging, the method for suppressing the sewage of the second sewage channel may be selected.

In the flushing structure shown in Fig. 2, two implementation methods are used to achieve the suppression of the sewage flow of the second sewage channel, but any single implementation method can achieve the same suppression purpose, and all fall within the scope of the present application.

The first implementation method is to set the highest point of the second sewage channel higher than the highest point of the first sewage channel.

As shown in FIG. 2, the highest point STP of the second sewage channel 16 is set higher than the highest point of the first sewage channel 12. When the basin water surface PL rises, the first sewage channel 12 takes the lead in discharging the dirt and even takes the lead. The siphon phenomenon is generated, which causes the water surface ascending speed to decrease or even decrease, so that the water flowing in the second sewage passage is lowered or even stopped, thereby achieving the purpose of suppressing the sewage discharge.

In the second embodiment, a cross-sectional changing unit that reduces the cross-section of the second sewage passage is provided in the second sewage passage 16.

As shown in FIG. 2, when the first sewage channel is used for sewage discharge, the pump unit does not work, the spring 213 is compressed to a small extent, and the diaphragm 214 blocks the water inlet of the pump unit, and the partial cross-sectional area of the second sewage channel is 0. The second sewage channel 16 is in a state of being cut off, and the second sewage channel is inhibited from being discharged when the first sewage channel is discharged.

When the second sewage channel is drained, the impeller in the pump unit rotates, the suction end generates suction, the diaphragm 214 is sucked open, and the spring 213 continues to be compressed, and the cross section in the second sewage passage 16 becomes larger and becomes conductive. Thus, the discharge of liquid contaminants can be performed.

Second toilet flushing structure

Comparing the existing toilet flushing structure and FIG. 1 with reference to FIG. 3, FIG. 4 and FIG. 5, wherein FIG. 3 and FIG. 5 show two embodiments of the second toilet flushing structure, and FIG. 4 shows that the scheme shown in FIG. Schematic diagram of the channel for sewage discharge. As can be seen from the figure, the second toilet flushing structure has the same pot portion 11 as the conventional toilet flushing structure shown in FIG. 1, the first sewage passage 12 including the first sewage passage rising portion 121, the washing water supply port 13, The upper rinsing portion 14, the lower rinsing portion 15, and the toilet venting port 17. further have: a second sewage channel 16 that can also be discharged, wherein 16 has: at the bottom of the basin portion 11 or at the bottom of the first sewage channel rising portion 121 or the lower effluent portion a second sewage channel inlet 161, a second sewage channel rising portion 162, a second sewage channel sewage outlet 164, and a connecting pipe 163 connecting the second sewage channel rising portion 162 and the second sewage channel sewage outlet 164 for suppressing a gas suppression unit that enters the second drain passage from the second drain passage 164, wherein the second drain 164 Below the second drain passage inlet 161, the gas suppression unit is lower than the basin water cover, and the second drain passage is thinner than the first drain passage.

The flushing structure also has a variable pressure mechanism for reducing the air of the air column section in the second drain passage 16, the air column section being comprised of a second drain passage between the gas suppression unit and the basin water.

When not in use, the bowl portion 11, the second sewage passage rising portion 162, and the first sewage passage rising portion 121 together form a water storage portion to store the washing water entering from the washing water supply port, thereby forming water to form a water seal. The purpose, as shown in Figure 3, is that the toilet water surface PL achieves the stench and insect proof of the building pipe.

When the user performs urination and uses the second sewage channel for sewage discharge, the driving pressure changing mechanism starts to discharge the air in the gas column section. For the gas column section, one end is water and the other end is to suppress air into the second. The air suppressing unit of the sewage channel, when the air entering the gas column section is smaller than the discharged air, a negative pressure is generated at both ends of the gas column section, so that the basin water flows over the second sewage channel rising section 161 to the gas suppressing unit. Continue to exhaust the air in the gas column section until all the air is discharged. At this time, because the height of the basin water is higher than the height of the gas suppression unit, and both are liquid, under the action of gravity pressure difference, from the second The siphon phenomenon occurs between the channel inlet and the air suppression unit. Since the former is higher than the latter, the siphon will continue until the inlet of the second sewage outlet of the basin stops when the air enters the second sewage channel from the variable pressure mechanism. To achieve the purpose of effluent discharge from the basin.

When the user uses the first sewage channel to perform sewage discharge after the stool or urinating, the washing water supply port 13 passes through at least one of the washing water washing portion 14 or the washing number lower flushing portion 15, and flows to the bowl portion 11, 3 and the basin water surface PL in FIG. 5 rises instantaneously. When the rising speed is fast enough, a siphon is generated in the second sewage channel 16 and the first sewage channel 12 to discharge the dirt to achieve the purpose of discharging the dirt. .

A first embodiment of the second toilet flushing structure shown in FIGS. 3 and 4 will now be described, wherein FIG. 3 is a cross-sectional view of the toilet non-use body, and FIG. 4 is a cross-section of the sewage using the second drain passage. Figure.

In the toilet flushing structure, the second drain passage is constituted by the second water collecting portion 221 to suppress the air gas suppressing unit entering from the passage 164, and the product of the water collecting surface SUL of the rising portion of the second drain passage and the drain port of the second water collecting portion away from the toilet drain port The sealed space between the water surface SSFLs constitutes the air column section 222. At this time, the variable volume unit 223 is in a free state, the internal air pressure and the atmospheric pressure are substantially the same, and the water collecting surface SSFL of the second water collecting portion 221 away from the toilet sewage outlet and the near sewage discharge The water surface SSNL of the mouth is highly close.

When the user performs urination and uses the second sewage channel for sewage discharge, as shown in FIG. 4, the driving rod 226 is pulled to move the lower portion of the variable volume unit 223 downward, and the pleats of the variable volume unit 223 made of rubber are pulled apart. When the volume is increased and the pressure is reduced, the air of the air column section is sucked into the variable volume unit 223 through the communication pipe 224 under the pressure difference, and the water collecting surface SSFL and the second sewage discharging of the second water collecting portion 221 away from the toilet sewage outlet The water collecting surface SUL of the channel rising section 162 rises until it merges and enters the inside of the connecting pipe 224 that connects the variable pressure mechanism and the second sewage channel to form a new water level surface SWL, while the basin water surface PL and the toilet drain port are away from the toilet. The water level SSFL drops. For the second sewage channel 16, the inlet water level is higher than the outlet water level. When the gas is kept from entering the second sewage channel 16, the dirt will continue to be discharged until the air enters the air. Two sewage channels 16. In order to ensure that gas does not enter the interior of the second drain passage 16 from the connecting conduit 224, a water level sensor 232 for sensing the internal water level of the conduit 224 is provided at the communication conduit 224. During the flushing process, a feedback signal alerts the user or the central processor that the drive rod 225 is driven when no water is detected, otherwise the drive is stopped and the drive rod position is maintained. After all the dirt in the basin is discharged, the air enters the pipeline through the second sewage inlet 161, and the atmospheric pressure is applied to both ends of the second water, and the water level SSFL of the sewage outlet and the water level SSNL near the sewage outlet are high. equal. At this time, the drive lever 225 is released, and the deformed varactor unit 223 is returned to the initial state by the elastic restoring force.

When the user uses the first sewage channel to perform sewage discharge after the stool or urinating, the washing water supply port 13 passes through at least one of the washing water washing portion 14 or the washing number lower flushing portion 15, and flows to the bowl portion 11, The pelvic water surface PL of 3 instantaneously rises, and when the ascending speed is sufficiently fast, a siphon is generated in the second sewage passage 16 and the first sewage passage 12 to discharge the dirt.

After the sewage discharge is completed, the washing water supply port 13 supplies water to the bowl portion 11, and the basin water surface PL rises to a predetermined value, and a water seal is formed again. During this process, the SUL rises, but the other outlets of the gas column section 222 are sealed. Therefore, the volume is reduced and the internal air is in a compressed state. Since the internal volume of the varactor unit 223 and the connecting line 224 is much larger than the volume in which the SUL rise is reduced, according to the inverse relationship between the pressure and the volume in the gas equation, it can be known that the pressure of the gas column section 222 is slightly larger than the atmospheric pressure, and the SUL is slightly lower. At PL, SSFL is slightly lower than SSNL.

The following three suppression implementation methods are available:

Referring to FIG. 4, the first suppression method may set the highest point STP of the second sewage channel 16 to be higher than the highest point of the first sewage channel 12. When the basin water surface PL rises, the first sewage channel 12 takes the lead. The discharge of dirt is even the first to produce a siphon phenomenon, which leads to a decrease or even a decrease in the rising speed of the water surface, so that the water flowing through the second sewage passage is lowered or even stopped, thereby achieving the purpose of suppressing the sewage discharge.

The second suppression method is to provide a section change unit in which the cross section of the second drain passage is made smaller in the second drain passage 16. When the water level of the basin rises, the cross section of the second sewage passage is made smaller, and the sewage discharge of the second sewage passage is suppressed. In some embodiments, a ball valve is connected to the connecting pipe 163 as a cross-section changing unit. When the second sewage channel is used for discharging, the valve is opened to turn on the second sewage channel. When the first drain channel is used for draining, the valve is closed to close the second drain channel.

The third suppression method is: when the first sewage channel 12 is used for sewage discharge, the variable volume unit 223 is compressed to increase the pressure of the gas column section, and the second drainage channel rises the water surface SUL and the second sewage channel is separated from the second water storage portion. The SSFL of the toilet drainage outlet is lowered, so that the second sewage passage becomes difficult to conduct, thereby achieving the purpose of suppressing sewage discharge.

A second embodiment of the second toilet flushing structure shown in Fig. 5 will now be described, in which Fig. 5 is a cross-sectional view of the toilet in a non-use state.

In this embodiment, the variable volume unit 223 as the variable pressure mechanism in the first embodiment of the second toilet flushing structure is replaced with the pump unit 231 which can extract the air in the air column section, while optimizing The air outlet of the pump unit is connected to the drain port 17 through the exhaust port 234. The pump unit may be a self-priming pump capable of drawing air out and then drawing water out, or may be an air pump or the like.

For ease of understanding of the following, reference may be made to Figures 3 and 4 for comparison.

When not in use, the bowl portion 11, the second sewage passage rising portion 162, and the first sewage passage rising portion 121 together form a water storage portion to store the washing water entering from the washing water supply port, thereby forming water to form a water seal. The purpose is to achieve a stinky and pest control on the construction pipeline.

When the user performs urination and uses the second sewage channel for sewage discharge, the pump unit 231 opens the air in the air column section 222 which is composed of the rising section water surface SUL of the second sewage channel 16 and the water surface SSFL of the toilet drain port. When pumping out, the water level at both ends of the gas column section moves up until they communicate with each other, and moves up to the second sewage channel 16, and the water surface of the water surface SSFL that is far away from the toilet sewage outlet and the rising channel 162 of the second sewage channel The SUL rises to the new water level surface SWL after the water surface is connected, and at the same time, the basin water surface PL and the water surface SSFL away from the toilet sewage outlet are lowered. For the second sewage channel 16, the inlet water level is higher than the outlet water level. When the gas is kept from entering the interior of the second drain passage 16, the dirt will continue to be discharged until air is introduced into the second drain passage 16 after being evacuated. In order to ensure that the gas does not enter the interior of the second sewage passage 16 from the connecting pipe 224, a water level sensor 232 that senses the water level inside the communication pipe 224 is provided at the communication pipe 224, and the pump unit is exhausted or the pump unit is enlarged when water is detected. The exhaust speed, otherwise slow drive or stop drive. When all the dirt in the basin is discharged, the air enters the pipeline through the second sewage inlet 161, and the two sides of the second water are at atmospheric pressure, and the SSFL and SSNL are equal in height. At this time, the driving of the pump unit is stopped, and the residual liquid in the connecting pipe 224 is directed to the second water collecting portion 221, and then flows to the toilet drain port 17.

The pump unit can also be kept open during the discharge of the second drain channel. When a self-priming pump is used as the pump unit, the sewage flows out of the bowl from the second drain passage 16 and the exhaust port 234 simultaneously throughout the draining process while keeping the pump unit open.

When the user uses the first sewage channel to perform sewage discharge after the stool or urinating, the washing water supply port 13 passes through at least one of the washing water washing portion 14 or the washing number lower flushing portion 15, and flows to the bowl portion 11, The basin water surface PL of 5 is instantaneously raised, and when the ascending speed is sufficiently fast, a siphon is generated in the second drain passage 16 and the first drain passage 12 to discharge the dirt.

Further, in order to improve the performance when the first sewage channel 12 performs sewage discharge, and avoid the interference between the performance of the two curved pipe lines, when the first sewage channel is used for sewage discharge, the method for suppressing the sewage discharge of the second sewage channel may be selected. .

The first embodiment of the second toilet flushing structure is the same, and the second embodiment also has the following three suppression methods:

The first suppression method, as shown in FIG. 5, can set the highest point STP of the second sewage channel 16 to be higher than the highest point FTP of the first sewage channel 12. When the basin water surface PL rises, the first sewage channel 12 The first to discharge the dirt and even lead to the siphon phenomenon, resulting in a decrease or even decrease in the rising speed of the water surface, so that the water flowing through the second sewage channel is reduced or even stopped, thereby achieving the purpose of suppressing the sewage.

The second suppression method is to provide a section change unit in which the cross section of the second drain passage is made smaller in the second drain passage 16. When the water level of the basin rises, the cross section of the second sewage passage is made smaller, and the sewage discharge of the second sewage passage is suppressed. In some implementations, in the connecting tube 163 A ball valve is connected as a cross-section changing unit, and when the second sewage channel is used for discharging, the valve is opened to turn on the second sewage channel. When the first drain channel is used for draining, the valve is closed to close the second drain channel.

The third suppression method is that when the first sewage channel 12 is used for sewage discharge, the pump unit 231 injects air into the second sewage channel 16, so that the pressure of the gas column section rises, so that the second sewage channel rises the water surface SUL and the second The water storage surface SSFL of the second water accumulation portion of the sewage passage away from the toilet sewage outlet is lowered, so that the second sewage passage becomes difficult to conduct, thereby achieving the purpose of suppressing sewage discharge.

A third embodiment of the second toilet flushing structure shown in Fig. 6 will now be described, in which Fig. 6 is a cross-sectional view of the toilet in a non-use state.

In this embodiment, the second water collecting portion 221 as the air gas suppressing unit for suppressing entry from 164 in the second embodiment of the second toilet flushing structure is replaced with a partial sectional area which can change the second passage. The cross-section changing unit, in this embodiment, the cross-section changing unit is constituted by a one-way valve 165, and the gas and the liquid can flow through the one-way valve 165 to the second drain passage drain port 164, but cannot flow in the opposite direction. The corresponding gas column segment is composed of a gas column between the rising surface water surface SUL and the check valve 165 in the second sewage channel 16.

When the user performs urination, when the second sewage channel is used for sewage discharge, the pump unit 231 opens to evacuate the air in the air column segment formed by the rising water surface SUL and the check valve 165 in the second sewage channel 16, the check valve At 165, the pelvic water flows to the check valve 165 until the gas column segment disappears, the water surface rises up to the new water level surface SWL position and moves up to the second sewage channel 16 above, and the water surface SSFL and the sewage drain port away from the toilet are discharged. The water collecting surface SUL of the rising portion 162 of the second sewage channel rises to the new water level surface SWL after the water surface is connected. At this time, for the second sewage channel 16, the inlet water level is higher than the outlet water level, and the gas is not allowed to enter the second sewage channel. Under the premise of 16, the pump unit is stopped, and the check valve 165 is opened under the action of gravity, and the dirt is siphoned under the action of gravity to discharge the bowl to the toilet drain port 17. In order to ensure that the gas does not enter the interior of the second sewage passage 16 from the connecting pipe 224, a water level sensor 232 that senses the water level inside the communication pipe 224 is provided at the communication pipe 224, and the pump unit is exhausted or the pump unit is enlarged when water is detected. The exhaust speed, otherwise slow drive or stop drive.

When the user uses the first sewage channel to perform sewage discharge after the stool or urinating, the washing water supply port 13 passes through at least one of the washing water washing portion 14 or the washing number lower flushing portion 15, and flows to the bowl portion 11, The pelvic water surface PL of 6 rises instantaneously, and when the ascending speed is sufficiently fast, a siphon is generated in both the second sewage passage 16 and the first sewage passage 12 to discharge the dirt.

The third embodiment also has the following two suppression methods:

The first suppression method, as shown in FIG. 6, can set the highest point STP of the second sewage channel 16 to be higher than the highest point FTP of the first sewage channel 12. When the basin water surface PL rises, the first sewage channel 12 takes the lead in discharging the dirt or even the first siphon phenomenon, thereby causing the water surface ascending speed to decrease or even decrease, so that the water flowing in the second sewage channel is lowered or even stopped. In order to achieve the purpose of suppressing sewage.

The second suppression method is to provide a section change unit in which the cross section of the second drain passage is made smaller in the second drain passage 16. When the water level of the basin rises, the cross section of the second sewage passage is made smaller, and the sewage discharge of the second sewage passage is suppressed.

A fourth embodiment of the second toilet flushing structure shown in Fig. 7 will now be described. In this embodiment, the second water collecting portion 221 as the air gas suppressing unit for suppressing entry from 164 in the second embodiment of the second toilet flushing structure is replaced with the area near the second drain opening port 164. A minimum channel 166 that is no larger than a circular area of 30 mm in diameter, preferably uses a circular hole having a diameter of 10 mm.

When the second sewage channel is used for sewage discharge, the pump unit is driven to extract the air in the gas column section, and the air in the vacuum gas column section flows to the outside, because the second sewage channel is connected to the sewage channel of the building, Under the partial negative pressure of the variable pressure unit, a part of the air enters the second sewage channel and is discharged by the pump. A part of the basin water rises into the sewage channel under the action of the negative pressure. Since gas continuously enters from the minimum channel 166, the water flow cannot flow out. The water surface accumulated in the rising section of the discharge section and the second sewage passage is continuously increased until the gas in the second sewage passage is evacuated, and only the gas sucked from the sewage outlet of the second sewage outlet is simultaneously discharged by the pump unit, ensuring that When the air in the second sewage passage is made to enter the air, the pump unit is stopped, the negative pressure acting on the minimum passage section pipeline disappears, and the accumulated water starts to flow to the second row. The sewage outlet of the sewage passage, the two ends of the second sewage passage are siphoned under the action of gravity, and the dirt is discharged. Keeping the air out of the second drain channel allows the siphon to continue until the dirt is completely drained.

In order to ensure that the gas does not enter the interior of the second sewage passage 16 from the connecting pipe 224, a water level sensor 232 that senses the water level inside the communication pipe 224 is provided at the communication pipe 224, and the pump unit is exhausted or the pump unit is enlarged when water is detected. The exhaust speed, otherwise slow drive or stop drive.

When the user uses the first sewage channel to perform sewage discharge after the stool or urinating, the washing water supply port 13 passes through at least one of the washing water washing portion 14 or the washing number lower flushing portion 15, and flows to the bowl portion 11 and the basin. The water surface of the part of the water rises instantaneously. When the rising speed is fast enough, a siphon is generated in the second sewage channel 16 and the first sewage channel 12 to discharge the dirt, and the drainage of the second sewage channel is performed because the 166 hole is thinner. Suppression reduces the interference of performance when the two pipes are discharged.
