In order to improve the sewage flushing effect, the water storage amount in the initial state needs to be increased. However, if the capacity of the cleaning surface in the toilet bowl is increased in the initial state, although the water storage amount is increased, the waste of water resources is caused, namely, a certain amount of water is required to be used more at each time, and the low-carbon and energy-saving concept is not satisfied.

One embodiment of the present application provides a pollution discharge control method applied to a toilet (shown in fig. 1).

As shown in fig. 3, 5, and 7, the toilet includes a toilet seat 200, a flushing device, and a soil pipe 2. The toilet seat body 200 is provided with a basin cavity 202, the inner wall surface of the local part of the basin cavity 202 is a cleaning surface 2080, and the space enclosed by the cleaning surface 2080 is communicated with a sewage discharge pipe 2 and is used for storing water to form water seal. The soil pipe 2 is communicated with the soil outlet 204 of the toilet seat 200 and can rotate relative to the toilet seat 200.

In one embodiment, the toilet further includes a waste box 1, a driving device 3, and a washing device 4, as shown in fig. 2, 4, 6, 8, and 10. The sewage discharging box 1, the sewage discharging pipe 2, the driving device 3 and the cleaning device 4 form a rear sewage discharging system 100 of the closestool. The sewage discharge box 1 is fixedly connected at the sewage discharge outlet 204 of the toilet seat body 200, and the sewage discharge pipe 2 is positioned in the sewage discharge box 1. The driving device 3 is connected with the sewage discharge pipe 2 and is used for driving the sewage discharge pipe 2 to rotate. The cleaning device 4 is connected with the sewage discharging box 1 and is used for spraying cleaning liquid into the sewage discharging box 1 to clean the sewage discharging box 1 and the sewage discharging pipe 2.

As shown in fig. 9 and 10, the soil pipe 2 includes a soil inlet pipe section 21 and a soil outlet pipe section 22. The sewage inlet pipe section 21 is communicated with the sewage outlet 204 of the toilet seat body 200 and can rotate relative to the toilet seat body 200. The sewage discharge pipe section 22 is connected with the sewage inlet pipe section 21 and is positioned in the sewage discharge box 1. The end of the waste pipe section 22 remote from the waste pipe section 21 forms a waste outlet 221. In the sewage disposal process, the sewage discharge pipe 2 rotates from top to bottom, discharges the sewage into the sewage discharge box 1, and discharges the sewage into the shifter through the sewage outlet 112 of the sewage discharge box 1, so as to enter an external sewage discharge channel.

The rear sewage system 100 is used for replacing a traditional siphon pipeline sewage discharge/flushing mode, adopts a falling and discharging type structure mode, and discharges the sewage in the toilet out of a toilet cleaning surface 2080 and a toilet pipeline by utilizing a natural gravity falling mode. In the sewage discharging process, the sewage discharging pipe 2 rotates around the rotation axis to pour and discharge sewage, and under the action of gravity and discharging inertia, the sewage in the toilet cleaning surface 2080 is efficiently and quickly discharged through the sewage discharging pipe 2.

Wherein, blow off pipe 2 sets up to rotate between blowdown initial position, standby position, blowdown position, and at the pivoted in-process of blow off pipe 2, the position of the drain 221 of blow off pipe 2 can change, leads to the position of the minimum of drain 221 to change. The lowest point of the soil discharge opening 221 when the soil discharge pipe 2 is in the standby position is lower than the lowest point of the soil discharge opening 221 when the soil discharge pipe 2 is in the initial soil discharge position. Therefore, the position of the lowest point of the drain outlet 221 of the drain pipe 2 can be changed by adjusting the position of the drain pipe 2 by rotation, and the water seal height of the toilet can be adjusted.

Therefore, the height difference between the initial water seal surface 2060 and the water seal surface 2060 during drainage can be controlled during drainage, so that the drainage efficiency is increased, and the drainage effect is improved, while the height of the initial water seal surface 2060 can be relatively lower, so that the water saving effect is achieved.

As shown in fig. 25, the pollution discharge control method includes:

step S604: after the power is switched on, the blow-off pipe is controlled to rotate downwards from the blow-off initial position to the standby position, so that the position of the lowest point of the blow-off port of the blow-off pipe is lowered;

step S606: the flushing device is controlled to flush the inner wall of the closestool seat body, so that a water seal is formed in the closestool and the closestool enters a standby state.

The blowdown control method that this application embodiment provided can reset the detection to blow off pipe 2 after the closestool circular telegram, guarantees that blow off pipe 2 just opens the bath device and washes by water to closestool pedestal 200 inner wall when rotating to standby position (as shown in fig. 3 and fig. 4), waits that the interior water seal of closestool forms, and the closestool just gets into standby state.

Because the toilet bowl rotates from the initial sewage discharge position (shown in fig. 5) to the standby position (shown in fig. 3), the lowest point of the sewage discharge port 221 of the sewage discharge pipe 2 is lowered, and compared with the situation that the sewage discharge pipe 2 is located at the initial sewage discharge position in the standby state, the toilet bowl can reduce the water seal height of the toilet bowl in the standby state, further reduce the water storage amount in the toilet bowl cleaning surface 2080 in the standby state, is beneficial to saving water, can reduce the water consumption of the toilet bowl every time, and accords with the concepts of water saving, low carbon and energy saving.

When the toilet needs to discharge sewage, the sewage discharge pipe 2 can be firstly rotated upwards from the standby position (as shown in fig. 3 and 4) to the initial sewage discharge position, as shown in fig. 5 and 6, so that the water seal height of the toilet can be increased, and the water containing volume in the cleaning surface 2080 of the toilet is further increased. The increased water volume in the cleaning surface 2080 of the toilet is helpful to increase the gravitational potential energy of the dirt and water. Because the sewage discharge pipe 2 mainly discharges sewage by means of gravitational potential energy, the larger the water containing volume in the cleaning surface 2080 of the toilet is, the stronger the gravitational potential energy is, and the faster the sewage discharge flow rate is, the more favorable the improvement of the sewage discharge efficiency and the sewage discharge effect are.

In an exemplary embodiment, as shown in fig. 26, the emission control method further includes:

step S602: after the power is on, the blow-off pipe is controlled to rotate to the blow-off initial position from the initial position before the power is on.

After step S602, step S604 is performed.

Because the position of blow off pipe 2 under the outage state probably changes because of external force or other factors, and the rotation angle that rotates to standby position by blowdown initial position is fixed, consequently, the circular telegram back, controls blow off pipe 2 earlier and rotates to blowdown initial position, can rectify the position of blow off pipe 2, then rotates preset angle again, can guarantee that blow off pipe 2 rotates to standby position, is favorable to improving control accuracy like this.

In an exemplary embodiment, as shown in fig. 27, the emission control method further includes:

step S608: in a standby state, confirming that the closestool enters a use state;

step S610: and controlling the sewage discharge pipe to rotate upwards to the initial sewage discharge position so as to enable the position of the lowest point of the sewage discharge outlet of the sewage discharge pipe to be raised.

In other words, when the soil pipe 2 is at rest at the standby position, the soil pipe 2 is in a standby state where the water seal height of the toilet bowl is H0, as shown in FIGS. 3 and 4. When the soil pipe 2 is rotated upward to the initial soil drainage position, the height of the seal of the toilet bowl before the water flushing device flushes the toilet bowl body 200 is H0, as shown in fig. 5 and 6, and remains unchanged. The subsequent flushing device will flush, so that the water seal height of the toilet rises to H1, as shown in fig. 7 and 8. Therefore, when the toilet rotates from the standby position to the initial sewage discharge position, the water seal height of the toilet can rise Hs, and the gravitational potential energy of liquid and sewage in the pipe is correspondingly increased. The soil discharging pipe 2 is then rotated downward from the initial position of the soil discharging to the soil discharging position as shown in fig. 9 and 10, and the soil is discharged by using gravitational potential energy.

Therefore, the scheme realizes the rising of the position of the lowest point of the sewage discharge port 221 by controlling the sewage discharge pipe 2 to rotate upwards, further realizes the increase of the height of the water seal of the closestool, and has ingenious design and easy realization. In addition, the position of the lowest point of the drain port 221 of the drain pipe 2 is changed in a rotating mode, and only the control logic of the drain pipe 2 needs to be changed without changing the structure of the toilet, so that the product cost cannot be increased, and the toilet has the advantages of low cost and high utility.

After the toilet bowl enters a use state, the sewage discharge pipe 2 is firstly controlled to upwards rotate to a sewage discharge initial position from a standby position, so that the water storage amount of the sewage discharge pipe 2 before downwards rotating for sewage discharge can be increased, then the sewage discharge pipe 2 can downwards rotate, and as shown in fig. 9 and 10, the sewage can be quickly and efficiently discharged by utilizing the increased gravitational potential energy.

And in the prior art, when the toilet discharges the flushing water, the sewage discharge pipe 2 directly rotates downwards to discharge the sewage, and the sewage can be discharged only by using the water stored in the initial state. Therefore, compare in prior art, the pollution discharge control method that this application embodiment provided can promote the gravitational potential energy when blowdown, therefore can promote blowdown efficiency and blowdown effect, also is favorable to reducing the washing water consumption when blowdown, and can not cause the increase of the inside trapped water volume of closestool under the initial condition, can not cause the waste of water resource, satisfies the energy-conserving demand of low carbon.

In addition, through the standby position of adjustment blow off pipe 2, also can adjust the position of the minimum under the blow off pipe 2 standby state, and then adjust the water seal height of closestool under the standby state, be convenient for come the reasonable selection according to the structure of different closestool to improve the flexibility and the suitability of drainage 100.

step S612: after the toilet is confirmed to be in a use state, the flushing device is controlled to flush the inner wall of the toilet seat body, so that the cleaning surface of the toilet seat body is wetted and the water seal of the toilet is lifted.

In the process, water is flushed to the inner wall of the toilet seat body 200, so that on one hand, the cleaning surface 2080 of the toilet seat body 200 can be wetted, and the cleaning surface 2080 of the toilet seat body 200 is lubricated, so that the dirt is prevented from being stuck on the cleaning surface 2080, and the dirt on the cleaning surface 2080 can be prevented from sliding off quickly; on the other hand, water in the cleaning surface 2080 and the sewage discharge pipe 2 can be supplemented, so that the position of the water seal surface 2060 is increased, the water seal height is increased, the gravitational potential energy of sewage and liquid in the sewage discharge pipe 2 can be increased, and the improvement of the sewage discharge flow rate and the sewage discharge efficiency is facilitated.

Certainly, the step S612 can be omitted, in the sewage disposal flushing process, the flushing device can flush the inner wall of the toilet seat 200, and the flushed water can be used for increasing the water seal height, thereby contributing to improving the sewage disposal efficiency and the sewage disposal effect.

step S616: the flushing device is controlled to flush the inner wall of the closestool seat body, and the sewage discharge pipe is controlled to rotate downwards from the sewage discharge initial position to the sewage discharge position so as to discharge sewage.

In the process, the flushing device flushes water to the inner wall of the toilet seat body 200, the cleaning surface 2080 and the sewage discharge pipe 2 can be continuously flushed, the sewage discharge pipe 2 rotates from top to bottom, and rotary sewage discharge is carried out by utilizing the lower-discharge inertia and the gravitational potential energy of sewage and liquid, so that the sewage discharge flushing flow of the toilet is realized.

Wherein, the opening time of the flushing device can be consistent with the time of the sewage discharge pipe 2 starting to rotate from the initial sewage discharge position, and the opening time and the initial sewage discharge position can also be staggered. The closing time of the flushing device and the time when the sewage discharge pipe 2 rotates to the sewage discharge position can be consistent or staggered.

In an exemplary embodiment, the emission control method further includes: and receiving an externally input flushing instruction. After receiving the flush command inputted from the outside, step S616 is executed.

In other words, the user sends a flush command by operating (e.g., pressing a flush button on the remote control or the toilet), and the blowdown flush flow is started after receiving the user command. The scheme ensures that the closestool can execute the sewage discharge flushing process according to the manual control of the user, and can meet the instant requirement of the user.

In an exemplary embodiment, the emission control method further includes: confirming that the toilet bowl enters a state to be flushed. After confirming that the toilet bowl enters the to-be-flushed state, step S616 is performed.

In other words, after the closestool is confirmed to enter the to-be-flushed state, the sewage discharge flushing process can be automatically started without manual operation of a user, so that the automation degree of the product is improved, and the use experience of the user is improved.

In an exemplary embodiment, in the step of confirming that the toilet bowl is in the use state, the toilet bowl is confirmed to be in the use state by detecting a user seating signal. And in the step of confirming that the closestool enters the state to be flushed, confirming that the closestool enters the state to be flushed by detecting the seat-off signal of the user.

The toilet seat can be provided with a detection device, and when a user sits on the toilet seat, the state of the detection device changes, so that the user can confirm that the toilet enters a use state. When the user leaves the toilet seat after use, the state of the detection device is changed, so that the toilet can be confirmed to enter a to-be-flushed state.

In one example, the seating signal and the unseating signal include a gravity signal. In this case, the detection means may include a gravity sensor for detecting a change in the magnitude of gravity generated when the user sits on or leaves the toilet, thereby confirming the state of the toilet.

In another example, the seating and unseating signals include infrared signals. In this case, the sensing means may include an infrared sensor for confirming the state of the toilet by sensing a change in an infrared signal generated when a user sits on or leaves the toilet.

In an exemplary embodiment, in step S616, the flushing time period of the flushing device is in a range of 3S to 6S (e.g., 3S, 4S, 5S, 6S, etc.), and the rotation time period of the soil pipe 2 is in a range of 5S to 8S (e.g., 5S, 6S, 7S, 8S, etc.).

Through verifying, in the blowdown scouring flow, inject the washing by water device's the bath time long in above-mentioned within range, can use as little as possible water resource on guaranteeing to carry out effective basis that erodees to washing surface 2080 and blow off pipe 2, so both can avoid the bath time too short to lead to the blowdown to erode the effect not good, also can avoid the bath time too long to lead to the water consumption too much and increase the water waste.

In the blowdown scouring flow, the length of time of rotating the blowdown pipe 2 is limited within the range, so that the integral scouring blowdown time is shortened by using water on the basis of ensuring the blowdown scouring effect, and water seal is formed in the toilet bowl quickly.

Of course, in the sewage flushing flow, the flushing time of the flushing device and the rotation time of the sewage pipe 2 are not limited to the above range, and can be adjusted according to the needs.

In an exemplary embodiment, as shown in fig. 27, after step S616, the pollution discharge control method further includes:

step S622: controlling the blow-off pipe to rotate to a standby position;

step S624: the flushing device is controlled to flush the inner wall of the closestool seat body, so that a water seal is formed in the closestool and the closestool enters a standby state.

In other words, after the blowdown flush flow is finished, the blowdown pipe 2 is automatically reset to the standby position finally, as shown in fig. 3, the flushing device automatically flushes water to ensure that the toilet forms a water seal meeting the standard requirement, i.e., the toilet automatically returns to the standby state to wait for the next use.

In an exemplary embodiment, between step S616 and step S622, the pollution discharge control method further includes:

step S618: controlling the blow-off pipe to rotate upwards to an initial blow-off position;

step S620: and controlling the water way of the cleaning device to be communicated, so that the cleaning device sprays cleaning fluid to the inside of the sewage discharging box to clean the sewage discharging box and the sewage discharging pipe.

After the blowdown is washed away and is accomplished, rotate blow off pipe 2 to blowdown initial position earlier, make blow off pipe 2 be close to the blowdown district and hang the outer wall (the right side pipe wall of blowdown pipeline section 22 in the picture) that stays the filth easily and the distance between belt cleaning device 4 is nearer, belt cleaning device 4 sprays the washing liquid this moment, can wash away the internal face of blowdown box 1 and the outer wall that blow off pipe 2 is close to the blowdown district, will remain or hang and stay on 1 internal face of blowdown box and the filth of blow off pipe 2 outer wall and wash, guarantee the clean state of blowdown box 1 and blow off pipe 2.

Of course, the cleaning device 4 can also clean the pollution discharge box 1 and the pollution discharge pipe 2 when the toilet is in a standby state according to the needs of users.

step S614: after the closestool is confirmed to enter the use state, the water path of the cleaning device is controlled to be conducted, so that the cleaning device sprays cleaning liquid into the blowdown box of the closestool, and the inner wall surface of the blowdown box is wetted.

Before the blowdown is washed and is started, cleaning device 4 sprays the washing liquid, can carry out moistening treatment to the internal face of blowdown box 1, and the internal face of blowdown box 1 is more moist and lubricated after moistening treatment, is favorable to the filth to change the landing to reduce and remain or hang the filth on the internal face of blowdown box 1.

In an exemplary embodiment, in the step of controlling the flushing device to flush the inner wall of the toilet seat 200, so as to form a water seal in the toilet and enter the standby state, the flushing time of the flushing device is in a range of 5s to 8 s.

Through verification, in the above-mentioned step, inject the length of time of washing by water of bath device in above-mentioned within range, can use as little as possible water resource on the basis of guaranteeing to form the water seal of standard requirement, so both can avoid the length of time too short and lead to the water seal height to hang down when washing by water, also can avoid the length of time overlength of washing by water to lead to the water consumption too much and increase the water waste.

Of course, in the above steps, the flushing time length of the flushing device is not limited to the above range, and may be adjusted as needed.

In an exemplary embodiment, the toilet includes a water tank, and the flushing device includes a water pump; controlling the flushing device to flush the inner wall of the toilet seat 200 includes: the water pump is controlled to be started, and the water in the water tank is introduced into the toilet seat body 200 and flushed towards the inner wall of the toilet seat body 200.

Or the flushing device comprises a flushing valve which is arranged to be connected with an external water source; controlling the flushing device to flush the inner wall of the toilet seat 200 includes: the flush valve is controlled to be opened, and water from an external water source is introduced into the toilet seat 200 and flushed toward the inner wall of the toilet seat 200.

For a toilet with a water tank, external tap water enters the toilet and is stored in the toilet. Therefore, the water in the toilet seat 200 from the flushing device comes from the water tank, and the water is flushed to the inner wall of the toilet seat 200 by starting and stopping the water pump.

For a toilet without a cistern, the flush valve directly flushes water into the toilet seat 200.

Wherein, the toilet seat body 200 is provided with a brush ring, the brush ring is provided with a flushing hole, a flushing channel communicated with the flushing hole is arranged in the toilet seat body 200, and the water pump or the flushing valve is communicated with the flushing channel and flushes water to the inner wall of the toilet seat body 200 through the flushing hole.

In an exemplary embodiment, when the sewage drain 2 is in the initial position of sewage draining, a plane S1 passing through the rotation axis of the sewage drain 2 and perpendicularly bisecting the sewage inlet 211 of the sewage drain 2 is in a vertical state, as shown in fig. 7.

In other words, when the sewage draining pipe 2 is at the initial sewage draining position, the sewage draining pipe section 22 is in the vertical state, the lowest point of the sewage draining outlet 221 of the sewage draining pipe 2 is highest, the water sealing surface 2060 of the toilet is highest, and the gravitational potential energy is maximum, so that the sewage draining efficiency and the sewage draining effect are further improved.

In an exemplary embodiment, as shown in fig. 3, the rotation angle α of the soil pipe 2 is in the range of 10 ° to 20 °, such as 10 °, 13 °, 15 °, 18 °, 20 °, from the standby position to the initial position of soil discharge.

In general, the stand-by position of the sewage drain 2 is the same as the initial position of the sewage drain, that is, the sewage drain section 22 is located in the vertical state, and the gravity center of the sewage drain 2 and the internal liquid and the rotation axis of the sewage drain 2 are approximately in a vertical plane, so that the stress balance of the sewage drain system 100 is facilitated, and the load of the driving device 3 is relatively small. In the blowdown control method provided by the embodiment of the application, the standby position of the blowdown pipe 2 is different from the initial blowdown position, and the blowdown pipe section 22 of the blowdown pipe 2 is inclined when the standby position is equivalent to the standby position, so that the centers of the blowdown pipe 2 and the internal liquid deviate from the rotation axis of the blowdown pipe 2, and the load of the driving device 3 in the standby state is increased.

According to the scheme, the rotation angle alpha of the sewage discharge pipe 2 from the standby position to the sewage discharge initial position is limited within the range of 10-20 degrees, so that the excessive load on the driving device 3 caused by the weight of the sewage discharge pipe 2 and the liquid in the sewage discharge pipe in the standby state can be avoided, and the self-supporting and self-locking angle range of the driving device 3 can be met; on the other hand, the switching of the state of the sewage discharge pipe 2 is ensured to generate considerable volume difference on the cleaning surface 2080 of the toilet, thereby ensuring that the sewage discharge efficiency and the sewage discharge effect can be obviously improved.

Of course, the rotation angle α of the drain pipe 2 is not limited to the above range and can be adjusted as required when the stand-by position is rotated to the initial position for draining.

In an exemplary embodiment, as shown in fig. 11, the rotation angle β of the soil pipe 2 is in the range of 100 ° to 120 °, such as 100 °, 110 °, 120 °, from the initial soil discharge position to the soil discharge position.

Compare in blow off pipe 2 from top to bottom and rotate 180, inject the turned angle beta of blow off pipe 2 in above-mentioned within range, can enough satisfy rotatory blowdown demand, also can reduce the range of motion of blow off pipe 2, and then be favorable to reducing the volume of blowdown box 1, be favorable to the miniaturization of blowdown box 1, be favorable to improving the flexibility and the suitability of sewage disposal system 100.

In addition, because the influence of the time node in the early stage of the pollution discharge process on the pollution discharge effect is the largest, if the rotation range and the time are too long, the stability of the pollution discharge effect and the consistency of the effect are not facilitated. Therefore, the rotation angle beta of the sewage discharge pipe 2 is limited in the range, the movement time of the sewage discharge pipe 2 is also favorably shortened, and the whole sewage discharge effect is more stable.

Of course, the rotation angle β of the sewage pipe 2 is not limited to the above range and can be adjusted as required when the pipe is rotated from the initial sewage draining position to the sewage draining position.

In an exemplary embodiment, as shown in fig. 3, 5, 7 and 9, a rotation direction (as indicated by a rotation arrow in fig. 5) in which the soil 2 is rotated from the standby position to the initial position of the soil is opposite to a rotation direction (as indicated by a rotation arrow in fig. 9) in which the soil 2 is rotated from the initial position of the soil to the soil position.

In other words, during sewage disposal, the sewage discharge pipe 2 is rotated to the initial sewage disposal position along the first direction and then rotated to the sewage disposal position along the second direction. When the first direction is clockwise, the second direction is counterclockwise. When the first direction is counterclockwise, the second direction is clockwise.

Like this, the standby position is located between blowdown initial position and the blowdown position, is favorable to reducing the motion range of blow off pipe 2, and then is favorable to reducing the volume of blowdown box 1, is favorable to the miniaturization of blowdown box 1, is favorable to improving the flexibility and the suitability of drainage 100.

Of course, the rotation direction of the blow-off pipe 2 from the standby position to the blow-off initial position may be the same as the rotation direction of the blow-off pipe 2 from the blow-off initial position to the blow-off position.

In an exemplary embodiment, when the sewage drain 2 is in the sewage drain initial position, the sewage drain 221 of the sewage drain 2 is directed horizontally upward, as shown in fig. 5, 6, 7 and 8.

Like this, when blow off pipe 2 is in blowdown initial position, the water seal 2060 of closestool flushes with drain 221 for the inner space of blow off pipe 2 obtains make full use of, is favorable to promoting the gravitational potential energy of intraductal liquid and filth as far as possible, and then promotes blowdown efficiency and blowdown effect.

In an exemplary embodiment, when the sewage draining pipe 2 is in a standby state, the water seal height H0 of the closestool is more than or equal to 50mm, and the product is ensured to meet the national standard requirement.

As shown in fig. 28, an embodiment of the present application further provides an pollution discharge control device, which includes a processor 504 and a memory 502 storing a computer program, wherein the processor 504 executes the computer program to implement the steps of the pollution discharge control method according to any one of the above embodiments.

The processor may be an integrated circuit chip having signal processing capabilities. The Processor may be a general-purpose Processor, and includes a Central Processing Unit (CPU), a Network Processor (NP), and the like; but may also be a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), an off-the-shelf programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components. The various methods, steps and logic blocks disclosed in the embodiments of the present invention may be implemented or performed. A general purpose processor may be a microprocessor or the processor may be any conventional processor or the like.

As shown in fig. 1, 19, 20, 22, 23 and 24, an embodiment of the present application further provides a toilet including the pollution discharge control device provided in the above embodiment, so that all the advantages of the above embodiment are provided, and further description is omitted herein.

In an exemplary embodiment, as shown in fig. 14 to 17, the soil pipe 2 includes: a sewage intake section 21 and a sewage discharge section 22.

Wherein, the sewage inlet pipe section 21 is rotatably connected with the sewage discharging box 1 of the closestool, and the sewage inlet pipe section 21 is provided with a sewage inlet 211.

The sewage draining pipe section 22 is connected with the sewage inlet pipe section 21 and is arranged in a bending mode relative to the sewage inlet pipe section 21. One end of the sewage discharge pipe section 22, which is far away from the sewage inlet pipe section 21, is provided with a sewage discharge port 221, and the area of the sewage discharge port 221 is larger than that of the sewage inlet 211.

The sewage draining pipe 2 provided by the embodiment of the application comprises a sewage inlet pipe section 21 and a sewage draining pipe section 22. The sewage inlet pipe section 21 is provided with a sewage inlet 211 for the sewage in the basin cavity 202 of the toilet seat body 200 to enter. The sewage discharge pipe section 22 is provided with a sewage discharge port 221 for discharging the sewage in the sewage discharge pipe 2. The sewage discharge pipe section 22 is connected with the sewage inlet pipe section 21 and is bent relative to the sewage inlet pipe section 21, so that a height difference is generated between the position of the sewage discharge port 221 and the position of the sewage inlet 211, and sewage can be conveniently discharged under the action of gravity.

Because the sewage inlet pipe section 21 can be rotatably connected with the sewage discharging box 1 of the toilet, the sewage discharging pipe section 22 can be driven to rotate from top to bottom in the sewage discharging process so as to discharge the sewage in the sewage discharging pipe 2 into the sewage discharging box 1 by utilizing gravitational potential energy, and the sewage can enter the shifter through the sewage outlet 112 of the sewage discharging box 1 and then enter an external sewage discharging channel, as shown in fig. 9 and 10.

Compare in the scheme that advances dirty mouthful 211 and drain 221 diameter equal among the prior art, this scheme sets up the area that the area of drain 221 is greater than into dirty mouthful 211, has increased the area of drain 221 in other words, therefore is favorable to improving blowdown efficiency, reduces the probability that the filth hangs at drain 221.

In an exemplary embodiment, the intake pipe section 21 is a mirror-symmetrical structure. The symmetry plane S1 of the sewage intake section 21 extends in the extending direction of the sewage discharge section 22, and the sewage intake port 211 is provided in a circular shape. The drain port 221 is provided in a special shape as shown in fig. 15.

The sewage inlet pipe section 21 adopts a mirror symmetry structure, and the sewage inlet 211 is round, so that the structure is regular, and the processing and forming are convenient; it is also advantageous to simplify the sealing structure between the waste pipe section 21 and the waste box 1.

During the rotary blowdown process, the initial blowdown position of the blowdown pipe section 22 is generally in the vertical state, as shown in fig. 7 and 8, i.e., the blowdown outlet 221 is horizontally up. Thus, the extension direction of the waste pipe section 22 in this state is the vertical direction. Since the symmetry plane of the sewage inlet section 21 extends along the extension direction of the sewage pipe section 22, the symmetry plane of the sewage inlet section 21 is the vertical plane of the sewage inlet section 21 when the sewage pipe 2 is in the initial position.

The sewage draining outlet 221 is specially-shaped, and the sewage draining outlet 221 can be enabled to be properly expanded outwards only on the basis of the existing circular shape, so that the area of the sewage draining outlet 221 can be larger than that of the sewage inlet 211. In the design process, the tail end of the sewage discharge pipe section 22 is only required to be properly expanded and deformed outwards, so that the improvement is facilitated on the basis of the existing sewage discharge pipe 2, and the area of the sewage discharge port 221 is increased under the condition that the whole volume of the sewage discharge pipe 2 is basically unchanged, so that the sewage discharge efficiency and the sewage discharge effect are improved.

In an exemplary embodiment, as shown in fig. 17, the waste section 22 is divided into a dump portion 222 and a non-dump portion 223 with the plane of symmetry of the waste section 21 being the interface 212 (coplanar with plane S1 in fig. 7 and plane S1 in fig. 15). The soil pipe 2 is rotated toward the side where the dumping part 222 is located during the rotation.

Wherein, the area of the dumping part 222 near the sewage draining exit 221 is provided with a diversion inclined plane 2221, as shown in fig. 17. The guide slope 2221 extends obliquely in a direction away from the interface surface 212 in a direction toward the soil discharge opening 221.

Because the sewage pipe 2 only needs to rotate to one side in the rotating process, namely to the side where the dumping part 222 is located, the sewage can flow to the sewage outlet 221 along the inner wall surface of the dumping part 222 as far as possible under the action of gravity and is discharged. Therefore, the area of the dumping part 222 close to the sewage outlet 221 is provided with the flow guiding inclined plane 2221, which is equivalent to that an inclined port is added at the opening of the traditional regular cylindrical structure, so that the sewage can be guided well, the flow rate of the sewage can be improved, the sewage can be discharged from the sewage outlet 221 quickly and smoothly, and the sewage discharge efficiency can be improved.

And, the setting of direction inclined plane for drain 221 forms special-shaped opening, and is bigger than traditional circular opening area, also is favorable to promoting the blowdown flow of drain 221, and then promotes blowdown efficiency.

The increase of the flow rate and the flow rate of the sewage discharge can reduce the probability of the sewage hanging at the sewage discharge port 221, thereby improving the sewage discharge effect.

In an exemplary embodiment, the angle of inclination of the deflector ramp 2221 relative to the interface surface 212 is in the range of 10 ° to 20 °, as shown in fig. 18.

The inclination angle of the diversion inclined plane 2221 relative to the interface 212 is limited within the range of 10 degrees to 20 degrees, so that the problems that the drainage pipe section 22 occupies too much space due to the overlarge inclination angle of the diversion inclined plane 2221, the volume of the drainage box 1 is increased due to the increase of the occupied space of the drainage pipe section 22, and the miniaturization of the drainage box 1 is not facilitated are avoided.

As shown in fig. 18, in a comparative example, the inclination angle of the deflector slope 2221 is increased to 30 °, the width of the soil discharge opening 221 in the left-right direction is increased by a 1. In another comparative example, the inclination angle of the guide slope 2221 is increased to 45 °, the width of the soil discharge opening 221 in the left-right direction is increased by a 2. Thus, the space occupied by the soil pipe 2 is increased. As shown in fig. 12, when the sewage pipes 2 rotate by the same angle to reach the sewage draining position, the volume of the sewage draining box 1 needs to be increased correspondingly due to the increase of the inclination angle of the air guiding inclined plane 2221, which is not favorable for the miniaturization of the sewage draining box 1.

Therefore, the inclined angle of the diversion inclined plane 2221 relative to the interface 212 is limited within the range of 10 degrees to 20 degrees (such as 10 degrees, 13 degrees, 15 degrees, 18 degrees, 20 degrees and the like) by the scheme, so that the sewage discharge efficiency and the sewage discharge effect of the sewage discharge pipe 2 can be improved on the basis of small volume change, the miniaturization of the sewage discharge box 1 is also facilitated, and the flexibility and the adaptability of the sewage discharge system 100 can be improved.

In one exemplary embodiment, the waste pipe section 22 includes a straight pipe section 224 and a contoured pipe section 225, as shown in FIG. 14. The straight pipe section 224 is connected to the dirty pipe section 21. The special-shaped pipe section 225 is connected with the straight pipe section 224, and the special-shaped pipe section 225 is provided with a flow guiding inclined surface 2221.

The straight pipe section 224 may be generally cylindrical to facilitate smooth interface with the dirty pipe section 21. And the special pipe section 225 is provided with a flow guide inclined surface 2221, so that the sewage discharge efficiency and the sewage discharge effect can be improved.

And design like this for water conservancy diversion inclined plane 2221 is only located the terminal part of blowdown pipe section 22, and the length of water conservancy diversion inclined plane 2221 is shorter relatively, therefore the volume of blowdown pipe section 22 is less compared with regular cylindrical change, so be favorable to blow off pipe 2 to promote blowdown efficiency and blowdown effect on the basis that its volume change is little, also be favorable to the miniaturization of blowdown box 1, and then be favorable to promoting the flexibility and the suitability of blowdown system 100.

In an exemplary embodiment, the waste pipe section 22 is a mirror-symmetrical structure. The symmetry plane S2 of the waste pipe section 22 is perpendicular to the symmetry plane S1 of the waste pipe section 21, as shown in fig. 15.

As shown in fig. 15, the waste pipe section 22 is mirror-symmetrical in the front-rear direction with respect to the direction in the drawing, and the symmetrical surface S2 of the waste pipe section 22 extends in the up-down direction and the left-right direction. The sewage intake pipe section 21 is mirror-symmetrical in the left-right direction, and a symmetrical surface S1 of the sewage intake pipe section 21 extends in the up-down direction and the front-rear direction. Thus, the symmetry plane S2 of the waste pipe section 22 is perpendicular to the symmetry plane of the waste pipe section 21S 1.

Thus, the waste pipe section 22 is also relatively regular in shape and easy to machine. In addition, the force of the sewage discharge pipe section 22 is balanced, and the stability of the sewage discharge pipe 2 in the rotating process is improved.

In an exemplary embodiment, the central axis of the sewage inlet 211 intersects the central axis of the sewage outlet 221 in a plane of symmetry of the sewage inlet section 21, and the angle θ is less than 90 °, as shown in fig. 16.

Thus, an acute angle is formed between the sewage inlet direction of the sewage inlet 211 and the sewage discharge direction of the sewage outlet 221, instead of the right angle of the conventional right angle elbow.

Since the sewage drain 2 is in the initial position of sewage draining, as shown in fig. 5, 6, 7 and 8, the sewage drain section 22 is in a vertical state, the central axis of the sewage drain 221 also extends in a vertical direction. Since an acute angle is formed between the sewage inlet direction of the sewage inlet 211 and the sewage discharge direction of the sewage outlet 221, not a right angle of the conventional right angle elbow, the central axis of the sewage inlet 211 extends obliquely downward, not in a horizontal direction. Therefore, the sewage in the basin cavity 202 can rapidly enter the sewage discharge pipe 2 under the action of gravity, and the flow guide of the sewage can be facilitated, so that the sewage discharge efficiency and the sewage discharge effect can be further improved.

And, when the blow-off pipe 2 rotates to the blow-off position, as shown in fig. 9, fig. 10 and fig. 11, the blow-off pipe 2 forms a dual-inclination blow-off slide way similar to a rotary slide, and has two slopes, and the sewage in the basin cavity 202 firstly enters the first slope (i.e. the sewage inlet pipe section 21) through the sewage inlet 211 and then turns to the second slope (i.e. the blow-off pipe section 22) to be discharged quickly, thereby ensuring that the toilet can blow off sewage better and faster.

In an exemplary embodiment, the angle θ between the central axis of the sewage inlet 211 and the central axis of the sewage inlet 221 is in the range of 75 ° to 85 °, such as 75 °, 80 °, 85 °, on a plane of symmetry of the sewage inlet section 21.

This is also advantageous to prevent the sewage from turning sharply when the sewage is rotated from the sewage inlet pipe section 21 to the sewage discharge pipe section 22, so that the sewage discharge efficiency and the sewage discharge effect are better.

In an exemplary embodiment, the waste pipe section 22 is in circular arc transition with the waste pipe section 21, as shown in fig. 16.

In an exemplary embodiment, the diameter d of the dirt intake 211 is in the range of 55mm to 65mm, as shown in FIG. 16.

The pipe diameter of traditional blow off pipe 2 is generally in 45mm to 50 mm's within range, and the diameter of entering dirty mouthful 211 equals blow off pipe 2's pipe diameter, also is in 45mm to 50 mm's within range. And this scheme will be discharged dirty mouthful 211 diameter d and inject in 55mm to 65 mm's within range (like 55mm, 60mm, 65mm etc.), and dirty mouthful 211 area of advancing obviously increases, and the area of drain 221 is greater than the area of dirty mouthful 211, therefore the pipe diameter increase of whole blow off pipe 2 can promote the blowdown performance of scouring away the pipeline better, also is favorable to practicing thrift blowdown water, realizes the purpose of environmental protection and water conservation. The volume of the sewage discharge port 221 is not changed greatly, so that various factors such as structure, volume, environmental protection and the like are considered.

In an exemplary embodiment, the length of the sewage drain 2 is in the range of 130mm to 140mm, such as 130mm, 132mm, 135mm, 138mm, 140mm, etc.

Most of the length of the traditional siphon pipe is more than 700mm, and the pipe of the sewage discharge pipe 2 in the scheme is obviously shortened. The big pipe diameter cooperation short tube way can make the blowdown performance of blow off pipe 2 of this application embodiment more reliable and more reliable, is difficult for taking place to block up more.

In an exemplary embodiment, the end of the waste pipe section 21 remote from the waste pipe section 22 is further provided with a sealing boss 23 for mounting the sealing member 14, as shown in fig. 14, 15 and 16. The sealing boss 23 is annular, and the inner diameter of the sealing boss 23 is larger than the diameter of the dirt inlet 211.

The arrangement of the sealing boss 23 is convenient for the installation of the sealing element 14, is beneficial to realizing the sealing fit among the sewage discharge pipe 2, the sewage discharge box 1 and the toilet bowl 202, and prevents the leakage of sewage.

In an exemplary embodiment, the outer wall surface of the sealing boss 23 adjacent to the waste discharge opening 221 is connected to the outer wall surface of the waste discharge pipe section 22, as shown in fig. 16.

Thus, the length of the waste pipe section 21 is very small, the portion of the waste pipe section 21 connected to the non-pouring portion 223 of the waste pipe section 22 is even negligible, and the portion connected to the pouring portion 222 of the waste pipe section 22 is substantially circular arc-shaped. Thus, the dirty section 21 generally corresponds to a transition joint. Thus being beneficial to shortening the pipeline length of the sewage discharge pipe 2 and further being beneficial to improving the sewage discharge performance of the sewage discharge pipe 2.

In an exemplary embodiment, the waste box 1 includes a box body 11 and a box cover 12, as shown in fig. 2. The cartridge body 11 is provided with a rotation coupling hole 111 as shown in fig. 2. The box cover 12 is connected with the box body 11 in a covering manner. The exhaust system 100 further comprises a drive means 3. The box main body 11 is provided with a connection hole 121, and the soil discharge pipe 2 is provided with a connection part 24. The driving means 3 is connected to the connecting portion 24 through a connecting hole 121 for driving the soil pipe 2 to rotate. The drive means 3 may be a motor.

In an exemplary embodiment, the washing device 4 comprises a liquid inlet pipe 41 and a sprinkling member 42. The liquid inlet pipe 41 is communicated with the pollution discharge box 1. The spraying member 42 is connected to the liquid inlet pipe 41 for spraying the cleaning liquid into the soil discharging box 1.

Like this, feed liquor pipe 41 can feed through with outside washing source (like outside water source), introduces the washing liquid to blowdown box 1, sprays the washing liquid to blowdown box 1 in through spraying 42, plays the cleaning action to blowdown box 1, is favorable to discharging to remain or hang the filth of staying in blowdown box 1 to improve the cleanliness factor of blowdown box 1, improve health and sense organ, improve the use of product and experience the sense.

In an exemplary embodiment, the toilet seat 200 (shown in fig. 23 and 24) is provided with a flush port 2002 in communication with the basin 202, as shown in fig. 19 and 20. The flush port 2002 may take the form of a pipe fitting that is mounted at a corresponding location on the toilet seat 200 and interfaces with the first outlet of the diverter valve 206 via a conduit.

As shown in fig. 19, 20, 21 and 22, the toilet bowl further includes: a shunt valve 206. The shunt valve 206 is provided with a water inlet, a first water outlet and a second water outlet. One of the first water outlet and the second water outlet is communicated with the water inlet. The water inlet is arranged to be connected with a water source. A first water outlet is provided in communication with the flush port 2002 to supply water to the basin 202. The second water outlet is provided to communicate with the washing device 4 of the soil exhaust system 100 to supply water to the washing device 4.

When the toilet needs to be flushed and drained, the water inlet is communicated with the first water outlet, water enters the flushing port 2002 of the toilet after passing through the shunt valve 206, then enters the toilet basin cavity 202, enters the drain pipe 2 together with dirt in the basin cavity 202, rotates downwards along with the drain pipe 2 to be discharged out of the drain pipe 2, enters the shifter 2006 along with the dirt through the dirt outlet 112 of the dirt discharging box 1, and finally enters an external dirt discharging channel.

When the flushing and sewage discharging are finished, the shunt valve 206 can be switched to another water channel to conduct the water inlet with the second water outlet, water enters the cleaning device 4 after passing through the shunt valve 206, is sprayed to the inside of the sewage discharging box 1 through the cleaning device 4, and is cleaned inside the sewage discharging box 1, so that the cleanliness of the sewage discharging box 1 is improved, and the sewage discharging system 100 can keep a good sewage discharging effect.

In addition, before the toilet bowl flushes and discharges sewage, the water inlet can be communicated with the first water outlet, water enters the flushing port 2002 of the toilet bowl after passing through the shunt valve 206 and then enters the toilet bowl 202 to moisten the inner wall surface of the bowl cavity 202, so that sewage can timely slide off in the subsequent flushing and sewage discharging process, and the residual or hung on the sewage on the inner wall surface of the bowl cavity 202 is reduced.

Before blow off pipe 2 rotates the blowdown, also can switch on water inlet and second delivery port for water gets into belt cleaning device 4 behind shunt valve 206, sprays to blowdown box 1 inside through belt cleaning device 4, moistens the processing to blowdown box 1 internal face, is favorable to follow-up washing in-process filth in time landing, reduces to remain or hang the filth of staying on blowdown box 1 internal face.

Thus, by controlling the selective conduction of the internal waterway of the shunt valve 206, water can be supplied for different functions of the toilet. Compared with the scheme that a plurality of water valves are respectively communicated with the flushing port 2002 and the cleaning device 4, the scheme is favorable for reducing the number of parts and the length of a pipeline of the closestool, so that the structure of the closestool is simplified, and the product cost is reduced.

In an exemplary embodiment, the toilet seat 200 is provided with a plurality of water distribution openings at the top of the basin 202. The flush port 2002 communicates with the basin 202 through a plurality of water diversion ports.

In other words, the top of the toilet seat 200 is provided with a water inlet channel, water enters the water inlet channel through the flushing port 2002, and flows out of the water inlet channel through the plurality of water dividing ports to enter the basin 202, so that the inner wall surface of the basin 202 can be cleaned and wetted, the position of the water sealing surface 2060 of the toilet can be raised, and the gravitational potential energy of the dirt and the liquid in the sewage pipe 2 can be increased.

Because the closestool of this application embodiment, mainly through drive arrangement 3 drive blow off pipe 2 rotary motion downwards with the filth discharge, the principle mainly relies on the gravitational potential energy and the inertia of whereabouts realization whereabouts blowdown of intraductal filth and liquid, therefore the water that basin 202 top branch mouth provided can play the effect that promotes the blowdown effect, and need not to set up the jet in order to utilize the big rivers of jet to wash the filth into blow off pipe 2 in basin 202 bottom.

Therefore, the closestool provided by the embodiment of the application can cancel the jet orifice at the bottom of the basin cavity 202 and only reserve the water diversion port at the top of the basin cavity 202, and can reduce noise on the premise of ensuring the sewage discharge effect, thereby being beneficial to improving the use experience of a user.

Because the water flowing out from the water diversion port at the top of the basin cavity 202 flows downwards along the inner wall surface of the basin cavity 202, the water flow intensity is relatively low, and the noise is also low; the jet at the bottom of the basin 202 has large water flow and large noise.

It is worth to be noted that, the existing toilet without a water tank or with a water tank basically cleans the inner wall surface of the basin cavity 202 by water flowing out from a water diversion port at the top of the basin cavity 202, discharges excrement by spraying water through a jet orifice at the bottom of the basin cavity 202, and simultaneously generates a siphon function by utilizing an S-shaped pipeline of the ceramic seat body to realize a sewage discharge function. The sewage discharge is mainly characterized in that the S-shaped bent pipe is sprayed with large water flow through the spray opening, so that the use noise is high.

In the toilet provided by the embodiment of the application, the toilet seat body 200 only keeps the water diversion opening (or the cleaning water spraying opening of the brush ring) at the top of the basin cavity 202, and the spraying opening at the bottom of the basin cavity 202 is eliminated, so that the noise of the toilet in the sewage discharge and flushing process can be effectively reduced, and the use experience of a user is improved. And, through the direct blowdown of the upset of drive arrangement 3 control blow off pipe 2, cancelled the S return bend of current hydrocone type closestool, can shorten the blowdown route, realize quick blowdown function, and blowdown effect is good.

In an exemplary embodiment, the toilet further includes: a water storage tank 210 and a water pump 208 as shown in fig. 19 and 20. The input end of the water pump 208 is communicated with the water storage tank 210, and the output end of the water pump 208 is communicated with the water inlet, and is used for pumping the water pump 208 in the water storage tank 210 into the water diversion valve 206.

Therefore, the on-off of the water path in the toilet can be controlled by controlling the on-off of the water pump 208; by controlling the shunt valve 206, the switching of the waterway inside the shunt valve 206 can be controlled, thereby facilitating the realization of automatic control.

In an exemplary embodiment, the toilet seat 200 is provided with a mounting chamber 2004. as shown in fig. 19 and 20, the mounting chamber 2004 is located on the rear side of the basin 202. Located within mounting chamber 2004 are exhaust system 100, at least a portion of diverter valve 206, at least a portion of water storage tank 210, and water pump 208.

Like this, compare in the scheme of establishing storage water tank 210 in closestool pedestal 200 top, the closestool of the embodiment of this application, overall structure is comparatively compact, and the volume is less relatively, both is convenient for store, transport, also can reduce the installation space of closestool, is favorable to reducing the occupation to the bathroom space.
