Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described in detail hereinafter with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be arbitrarily combined with each other.

As shown in fig. 3, an embodiment of the present application provides a sewage disposal box 1 applied to a toilet. The toilet also comprises a drain pipe 2. The sewage draining box 1 is provided with a rotary connecting hole 13 as shown in fig. 1. The rotary connection hole 13 is provided in rotary connection with the drain pipe 2. The drain pipe 2 is at least partially arranged in the drain box 1 and rotates around the rotation connecting hole 13.

As shown in fig. 12, the vertical surface where the central axis of the rotary connecting hole 13 is located is taken as an interface 15, the inner wall surface of the sewage box 1 is divided into a sewage area 11 and a non-sewage area 12, and the sewage pipe 2 rotates from the side of the non-sewage area 12 to the side where the sewage area 11 is located in the process of rotary sewage. In fig. 12, a portion of the inner wall surface of the sewage box 1 located within the left thin broken line box is a non-sewage area 12; the part of the inner wall surface of the sewage disposal box 1 positioned in the thick dash-dot line square frame on the right side is a sewage disposal area 11.

The non-pollution discharge area 12 and the pollution discharge area 11 are asymmetrically arranged with respect to the interface 15, as shown in fig. 12, and the space enclosed by the pollution discharge area 11 is larger than the space enclosed by the non-pollution discharge area 12.

The sewage draining box 1 provided by the embodiment of the application is provided with a rotary connecting hole 13, and the rotary connecting hole 13 is used for being in rotary connection with the sewage draining pipe 2. The sewage inlet of the sewage pipe 2 is communicated with the sewage outlet of the basin 202 of the toilet seat 200. The main body of the sewage drain pipe 2 is positioned in the sewage drain box 1 and can rotate from top to bottom in the sewage drain box 1. When sewage is discharged, sewage in the toilet bowl 202 enters the sewage discharge pipe 2, and is discharged out of the sewage discharge pipe 2 under the action of gravity along with the downward rotation of the sewage discharge pipe 2, and is discharged out through the sewage outlet 14 of the sewage discharge box 1, as shown in fig. 7 to 9.

Because the blow-down pipe 2 only needs to rotate to one side in the process of rotating blow-down, namely to the side where the blow-down area 11 is located, as long as the side where the blow-down area 11 is located has enough space, the rotating requirement of the blow-down pipe 2 can be met, and the space size of the non-blow-down area 12 has no influence on the rotating requirement of the blow-down pipe 2.

Based on this, the sewage draining box 1 provided by the embodiment of the application adopts an irregularly-arranged irregular shape, and the sewage draining area 11 and the non-sewage draining area 12 are designed into an asymmetrically-arranged shape. Moreover, the space surrounded by the sewage draining area 11 is relatively large so as to meet the rotation requirement of the sewage draining pipe 2, and the space surrounded by the sewage draining area 12 is relatively small. Compared with the prior art, the size of the non-pollution discharge area 12 is reduced, so that the space enclosed by the non-pollution discharge area 12 is reduced, the volume of the pollution discharge box 1 is reduced, the requirement of the pollution discharge box 1 on the assembly space is reduced, and the adaptability and the flexibility of the pollution discharge box 1 are improved.

In addition, the internal space of the pollution discharge box 1 is mainly distributed in the pollution discharge area 11, so that the internal space of the pollution discharge box 1 is mainly used for pollution discharge, the space utilization rate in the pollution discharge box 1 is improved, the available pollution discharge space is increased, and the probability of blockage is reduced.

Wherein, blow off pipe 2 can be located blow off box 1 inside completely, then blow off box 1 and closestool pedestal 200 fixed connection, blow off pipe 2 and blow off box 1 rotate to be connected, can establish seal structure between the junction of blow off pipe 2 and blow off box 1, also can establish seal structure between the junction of blow off box 1 and closestool pedestal 200.

Alternatively, the drain pipe 2 may be partially located within the drain box 1. For example, the sewage discharging box 1 is fixedly connected with the toilet seat 200. The sewage inlet pipe section of the sewage pipe 2 can penetrate through the rotary connecting hole 13 to extend out of the sewage box 1 and be inserted into the sewage outlet of the toilet seat body 200, so that the sewage outlet is communicated with the sewage outlet. And the sewage drain pipe 2 can rotate relative to the toilet seat 200 and the sewage drain box 1.

In addition, the connection part 23 of the sewage drain pipe 2 for connection with the driving device 3 may be located inside the sewage drain box 1 or may extend outside the sewage drain box 1.

It should be noted that, the sewage draining pipe 2 rotates from the side of the non-sewage draining area 12 to the side of the sewage draining area 11 during the sewage draining process, and only the rotation direction (clockwise rotation or anticlockwise rotation) of the sewage draining pipe 2 during the sewage draining process is limited, and the sewage draining initial position of the sewage draining pipe 2 is not limited. In the process of rotating the sewage discharge, the sewage discharge pipe 2 must rotate from top to bottom to discharge the sewage in the pipe by utilizing gravity, so that the rotation direction of the sewage discharge pipe 2 can be confirmed according to the relative positions of the sewage discharge area 11 and the non-sewage discharge area 12. While the initial position of the sewage draining pipe 2 can be in a vertical state, as shown in fig. 12, at this time, the sewage draining outlet 21 of the sewage draining pipe 2 can be partially positioned in the space at one side of the non-sewage draining area 12 and partially positioned in the space at one side of the sewage draining area 11; the initial position of the sewage discharge pipe 2 may be in a slightly inclined state, and the sewage discharge outlet 21 of the sewage discharge pipe 2 may be completely located in the space at one side of the sewage discharge area 11.

In an exemplary embodiment, the drain box 1 includes a box body 17 and a box cover 16, as shown in fig. 11. The cartridge body 17 is provided with a rotation coupling hole 13. The cover 16 is connected with the main body 17 in a covering way, and a sealing ring 18 can be arranged between the cover 16 and the main body 17. The cap 16 is provided with a coupling hole 161, and the drain pipe 2 is provided with a coupling part 23, and as shown in fig. 3, the driving device 3 is coupled to the coupling part 23 through the coupling hole 161 to drive the drain pipe 2 to rotate.

Wherein, the box main body 17 is arranged at the front side of the box cover 16, and the box main body 17 and the box cover 16 are irregularly shaped in the left-right direction.

The sewage box 1 is cut along the vertical direction perpendicular to the interface 15, and the contour line of the inner wall surface of the sewage box 1 is irregularly shaped in an asymmetric arrangement. The sewage box 1 is sectioned along the interface 15, and the outline of the inner wall surface of the sewage box 1 is approximately rectangular or rounded rectangle. The drain box 1 is cut along a horizontal direction perpendicular to the interface 15, and the contour line of the inner wall surface of the drain box 1 is also substantially rectangular or rounded rectangular.

Therefore, the shape of the sewage disposal box 1 is irregular, and can be seen clearly and intuitively from the front-rear direction in the figure.

Of course, the outer wall surface of the sewage draining box 1 may also include some other structures, such as a connecting lug, a connecting hole 161, etc., for realizing the installation and fixation of the sewage draining box 1 and the driving device 3.

In an exemplary embodiment, the width L1 of the region of waste 11 in a horizontal direction perpendicular to the interface 15 is greater than the width L2 of the region of non-waste 12 in a horizontal direction perpendicular to the interface 15, as shown in FIG. 12.

The width of the drain region 11 in the horizontal direction perpendicular to the interface 15 needs to be larger than the distance between the drain outlet 21 of the drain pipe 2 and the rotation axis of the drain pipe 2 (i.e., the central axis of the rotation connection hole 13), so that interference with the inner wall surface of the drain box 1 can be prevented when the drain pipe 2 rotates to the horizontal direction. The width of the non-sewage area 12 in the horizontal direction perpendicular to the interface 15 is not limited thereto, and can be designed smaller to reduce the volume of the sewage box 1.

Like this, blowdown box 1 has wholly formed the scheme of eccentric design, and the central axis that rotates connecting hole 13 is in the horizontal width direction of blowdown box 1 (i.e. left and right directions in the drawing) and is inclined to one side that non-blowdown district 12 is located, and is not located the position of the centre of blowdown box 1 horizontal width direction, so both can satisfy the rotatory demand of blow off pipe 2 unilateral, also can reduce blowdown box 1's volume, and then is favorable to improving the flexibility and the suitability of blowdown system 100.

In an exemplary embodiment, the blowdown zone 11 includes a transition zone 111, as shown in FIG. 14. The transition zone 111 is arranged to: during rotation of the drain pipe 2 relative to the drain box 1, the drain outlet 21 of the drain pipe 2 faces the transition zone 111, as shown in fig. 7 to 9.

Wherein the distance between the central axis of the rotation connection hole 13 and the transition zone 111 gradually increases in the top-down direction.

In the process of rotating the sewage discharge pipe 2 for discharging sewage, as the sewage discharge pipe 2 rotates from top to bottom, the sewage in the sewage discharge pipe 2 can be gradually discharged, the discharging speed is higher and higher, and the thrown distance is longer and longer. Therefore, when the distance between the central axis of the rotation connection hole 13 and the transition zone 111 is gradually increased in the top-down direction, the distance between the drain outlet 21 of the drain pipe 2 and the inner wall surface of the drain box 1 is also gradually increased during the process of rotating the drain. The probability that the dirt discharged by the blow-down pipe 2 is thrown onto the inner wall surface of the blow-down box 1 is reduced, and the dirt directly falls down with or without contacting the inner wall surface of the blow-down box 1 as little as possible, so that the dirt remained or hung on the inner wall surface of the blow-down box 1 is reduced, the cleanliness and the sanitation of the blow-down box 1 are improved, and the sensory feeling of a user is improved.

In an exemplary embodiment, the drain region 11 further comprises an outlet region 112 located on the underside of the swivel connection aperture 13, as shown in fig. 14. The outlet region 112 defines a dirt outlet 14 of the dirt tray 1, the central axis of the dirt outlet 14 being offset from the interface 15.

The sewage outlet 14 of the sewage box 1 is arranged at the lower part of the sewage area 11 in the scheme, so that the central axis of the sewage outlet 14 deviates from the interface 15, and the sewage outlet 14 of the sewage box 1 and the rotary connecting hole 13 (corresponding to the sewage inlet of the sewage box 1) are arranged in a staggered eccentric layout in the horizontal width direction (the left-right direction in the figure), namely: not just under the rotation connection hole 13, but under the side of the rotation connection hole 13.

Compared with the design that the sewage outlet 14 is directly arranged under the central axis of the rotary connecting hole 13, the staggered eccentric layout design of the scheme is beneficial to reducing the distance between the sewage outlet 21 of the sewage pipe 2 (at the highest position as shown in fig. 7) and the sewage outlet 14 of the sewage box 1, and further beneficial to shortening the rotating angle of the sewage pipe 2 from the initial position to the sewage position, thereby achieving the purpose of quick sewage discharge.

In addition, compared with the sewage outlet 14 directly arranged under the central axis of the rotary connecting hole 13 (as shown in fig. 13), the sewage box 1 adopts the design of staggered eccentric layout, so that the space occupied by the area of the sewage box 1 under the central axis of the rotary connecting hole 13 can be reduced, the volume of the sewage box 1 is further reduced, and the flexibility and the adaptability of the sewage box 1 are further improved.

In an exemplary embodiment, a longitudinal section perpendicular to the interface 15 is denoted as a longitudinal mid-plane, i.e. a section taken through the trapbox 1 in a vertical direction perpendicular to the interface 15. The contour line of the transition zone 111 in the longitudinal direction in the vertical plane includes a first section 1111, a second section 1112 and a third section 1113 which are connected in this order from the top down, as shown in fig. 14 and 15. The area corresponding to the third segment 1113 is configured to face the drain 21 of the drain 2 when the drain 2 is rotated to the drain position, as shown in fig. 9.

Wherein the third segment 1113 is configured as an inclined straight segment and extends obliquely downward in a direction approaching the non-sewage discharge region 12, as shown in fig. 14.

When the sewage discharge pipe 2 rotates to the sewage discharge position, the sewage in the sewage discharge pipe 2 is discharged outwards in a large amount. Since it is possible that the drain 21 of the drain pipe 2 is facing the corresponding area of the third section 1113 of the transition zone 111 at this time, a large amount of sewage may contact the area as shown in fig. 9 and then fall down along the area. Compared with the arrangement of the third segment 1113 as an arc segment (as shown by a dotted arc segment of a comparative example in fig. 15), the third segment 1113 is arranged as an inclined straight line segment, and the straight line segment is shorter than the arc segment in length, so that the area of the region corresponding to the third segment 1113 can be reduced, and dirt can be conveniently and rapidly separated from the region; the area can have a larger inclination angle, so that dirt can slide off efficiently and quickly, and a more efficient pollution discharge sliding effect is achieved.

In other words, the area corresponding to the third segment 1113 forms a drainage guide surface, which can perform a drainage guide function with high efficiency, as shown in fig. 9.

In an exemplary embodiment, the first section 1111 is configured as an arc shape and the second section 1112 extends in a vertical direction, as shown in fig. 14 and 15.

In this embodiment, the first section 1111 is set as an arc segment, and the second section 1112 is set as a vertical straight line segment, so that the area corresponding to the first section 1111 is an arc surface, and the area corresponding to the second section 1112 is a vertical surface (i.e. a plane perpendicular to the horizontal surface, or called a vertical surface). Compared with the first section 1111 and the second section 1112 being designed as a complete arc section, the present embodiment reduces the length of the second section 1112, so that the area of the area corresponding to the second section 1112 can be reduced, which is helpful for improving the sewage draining efficiency.

Moreover, compared with the arc surface, the vertical surface is less prone to be stained, and the stained materials hung on the vertical surface are more prone to slide down. In addition, compared with the arc surface, the vertical surface can reduce the width of the sewage disposal area 11 in the horizontal direction perpendicular to the interface 15 (i.e. the width in the left-right direction in the figure), and the space occupied by the sewage disposal area is smaller, thereby being beneficial to further reducing the volume of the sewage disposal box 1 and further improving the flexibility and adaptability of the sewage disposal box 1.

As a comparative example, the second section 1112 is designed as an arc section concentric with the first section 1111, as a broken line arc section of the comparative example is illustrated in fig. 15. The length of the second section 1112 in the comparative example was calculated to increase by about 6%.

In an exemplary embodiment, the outlet region 112 includes a fourth segment 1121 and a fifth segment 1122 along a longitudinal vertical line. The fourth segment 1121 is smoothly connected to the lower end of the third segment 1113, so that the dirt on the area corresponding to the third segment 1113 can smoothly slide into the dirt outlet 14 to be discharged, and the dirt discharging efficiency can be improved. The fifth section 1122 is spaced apart from the fourth section 1121, with the fifth section 1122 and the fourth section 1121 defining the dirt outlet 14 therebetween.

In an exemplary embodiment, the fifth section 1122 includes an outlet section 1123 and a transition section 1124, as shown in FIG. 14. The outlet section 1123 is disposed opposite the fourth section 1121 and forms a dirt outlet 14 with the fourth section 1121. The pouring surface 22 of the drain pipe 2 is provided with a flared portion in the drain pouring direction, as shown in fig. 9 and 10.

As shown in fig. 10, the outlet section 1123 is provided as: when the drain pipe 2 is rotated to the drain position, the outlet section 1123 is adapted to the contour of the pouring surface 22 of the drain pipe 2 in the longitudinal direction, such that the outlet section 1123 forms a flared guide for guiding the discharge of dirt. The pouring surface 22 of the drain pipe 2 is referred to as: when the sewage drain pipe 2 is in the sewage drain position, the dirt in the sewage drain pipe 2 can be discharged downwards along the side wall of the lower part of the inner side wall of the sewage drain pipe 2.

The lower end of the transition section 1124 is smoothly connected to the upper end of the outlet section 1123, and the upper end of the transition section 1124 is smoothly connected to the contour line of the non-sewage draining area 12 in the longitudinal direction.

In this scheme, when blow off pipe 2 is in the blowdown position, the regional area that outlet section 1123 corresponds is located the extension face of blow off pipe 2's empting face 22 to with the shape adaptation of blow off pipe 2's empting face 22, make the regional flaring guide part that has formed that outlet section 1123 corresponds, can play better guide effect to the filth, be favorable to filth along this position get into the filth export 14 of blow off box 1 fast smooth and easy high efficiency.

The area corresponding to the transition section 1124 has negligible effect on the dirt discharge, so that the transition section 1124 can be properly lifted and smoothly connected with the non-sewage draining area 12, so as to further reduce the volume of the sewage draining box 1.

In one example, the outlet section 1123 is rounded to facilitate smooth sliding of dirt along the area corresponding to the outlet section 1123.

In an exemplary embodiment, as shown in fig. 14, the contour line of the non-sewage discharge region 12 in the vertical direction includes a sixth section 121, a seventh section 122, and an eighth section 123 that are connected in this order from the top.

Wherein the sixth section 121 is smoothly joined to the first section 1111. The eighth segment 123 meets smoothly the contour of the outlet region 112 in the longitudinal direction.

Further, as shown in fig. 15, the sixth section 121 is provided in an arc shape and is the same as the center of the first section 1111. The seventh section 122 extends in a vertical direction as shown in fig. 15.

In this way, the sixth section 121 and the first section 1111 form a continuous arc, so that the shape of the portion forms a regular arc surface, which is convenient for processing and shaping. The seventh segment 122 is configured as a vertical straight segment, and the length of the straight segment is shorter and the distance from the central axis of the rotation connecting hole 13 is smaller than that of the arc segment configured concentrically with the sixth segment 121, so that the width of the non-sewage draining area 12 in the horizontal direction perpendicular to the interface 15 (i.e., the width in the left-right direction in the drawing) is advantageously reduced, and the volume of the sewage draining box 1 is advantageously further reduced.

As a comparative example, the sewage treatment cartridge 1 was designed in a regular shape, as a structure indicated by a broken line in fig. 16, the contour line of the inner wall surface of the sewage treatment cartridge 1 in the vertical direction was a regular circle, and the contour line was a complete circle formed by extending the first section 1111 and the sixth section 121.

According to calculation, the embodiment of the application adopts a special-shaped design with asymmetric left and right arrangement, so that the area (the area of a vertical plane in the longitudinal direction) and the whole volume of the inner wall surface of the sewage disposal box 1 can be reduced by about 34%, namely, the volume is reduced by more than 1/3, and the occupation of the sewage disposal box 1 to the space in the toilet bowl is greatly saved.

Therefore, the shape of the sewage disposal box 1 is optimized, the volume of the sewage disposal box 1 is effectively reduced, and the adaptability of the sewage disposal system 100 is improved to a great extent.

In an exemplary embodiment, the upper end of the seventh section 122 is higher than the upper end of the second section 1112, and the lower end of the seventh section 122 is higher than the lower end of the second section 1112, as shown in fig. 14.

Thus, the seventh section 122 is positioned relatively high and spaced from the interface 15 to further reduce the volume of the trapbox 1; the second section 1112 is positioned relatively low and spaced from the interface 15 to avoid interference between the discharge region 11 and the discharge tube 2 or excessive contact with contaminants.

In an exemplary embodiment, as shown in fig. 9, the space enclosed by the sewage draining area 11 is configured as follows: the maximum rotation angle alpha provided for the drain pipe 2 is in the range of 100 deg. to 120 deg..

In other words, the drain pipe 2 can only rotate 100 to 120 ° in the drain box 1 due to the limitation of the shape of the drain region 11, and can interfere with the drain box 1 if the rotation is continued.

Compared with the scheme that the drain pipe 2 rotates 180 degrees (from vertical upward rotation to vertical downward rotation), in the scheme, the drain pipe 2 only needs to rotate 100 degrees to 120 degrees, so that the rotation time is reduced, and the drain efficiency is improved. Meanwhile, the volume of the sewage disposal box 1 is reduced by the scheme, and the flexibility and the adaptability of the sewage disposal box 1 are improved.

As shown in fig. 11, 12 and 14, an embodiment of the present application further provides a sewage disposal system 100, including: a trapbox 1, a drain pipe 2 and a drive means 3 as in any of the above embodiments. The blow-down pipe 2 is rotatably connected with the blow-down box 1.

In an exemplary embodiment, the drain box 1 includes a box body 17 and a box cover 16, as shown in fig. 11. The cartridge body 17 is provided with a rotation coupling hole 13 as shown in fig. 1. The cover 16 is connected with the cover main body 17 in a covering way. A sealing ring 18 is arranged between the box cover 16 and the box main body 17, and a sealing piece 19 is arranged between the sewage draining pipe 2 and the sewage draining box 1 as shown in fig. 23. The box main body 17 is provided with a connection hole 161, and the drain pipe 2 is provided with a connection portion 23. The driving device 3 is connected to the connection part 23 through the connection hole 161 for driving the drain pipe 2 to rotate. The driving means 3 may be a motor.

The blowdown principle of the blowdown system 100 is as follows (as shown in fig. 7 to 9):

When the toilet is rotated for discharging sewage, the sewage in the basin 202 of the toilet seat 200 enters the sewage discharge pipe 2, the sewage discharge pipe 2 is driven by the driving device 3 to rotate from an initial position (namely, the position of the sewage discharge outlet 21 facing to the right upper side as shown in fig. 7) to reach a sewage discharge position (as shown in fig. 9) by 100-120 degrees, and the sewage is discharged from the sewage discharge outlet 21 and is discharged through the sewage outlet 14 of the sewage discharge box 1.

After the sewage discharging action is finished, the sewage discharged through the sewage discharging pipe 2 flows into the shifter 204 through the sewage inlet of the sewage discharging box 1 and then is led into an external sewage discharging channel, and a sealing ring 18 is arranged between the shifter 204 and the sewage discharging box 1. The sewage drain pipe 2 is reset to the initial position (shown in fig. 7) under the drive of the driving device 3, and is reused when the next sewage drain function is performed.

In an exemplary embodiment, the sewage system 100 further comprises a cleaning device 4, as shown in fig. 18 and 23. The cleaning device 4 is connected with the sewage box 1 and is used for spraying cleaning liquid into the sewage box 1, so that the sewage box 1 can be cleaned, residual or suspended dirt in the sewage box 1 can be discharged, the cleanliness of the sewage box 1 is improved, and a good sewage effect is maintained.

In an exemplary embodiment, as shown in fig. 23, the cleaning device 4 includes a liquid inlet tube 41 and a spray member 42. The liquid inlet pipe 41 is communicated with the sewage box 1. The spraying member 42 is connected to the liquid inlet pipe 41 for spraying the cleaning liquid into the sewage box 1.

Like this, feed liquor pipe 41 can with outside cleaning source (such as outside water source) intercommunication, introduce the washing liquid to blowdown box 1, spray the piece 42 with the washing liquid in to blowdown box 1, play the cleaning action to blowdown box 1, be favorable to discharging the filth that remains or hang in blowdown box 1 to improve blowdown box 1's cleanliness factor, keep good blowdown effect.

As shown in fig. 1 to 9 and 17 to 22, the present application also provides a toilet, including a toilet seat 200 and the sewage disposal system 100 of the above embodiments.

As shown in fig. 17 to 20, the toilet seat 200 is provided with a basin 202, and the basin 202 is provided with a sewage outlet 2006. The drain pipe 2 of the drain system 100 communicates with the drain outlet 2006, and the central axis of the drain outlet 2006 is collinear with the rotational axis of the drain pipe.

The toilet bowl according to the embodiment of the present application includes the sewage draining system 100 in the above embodiment, so that the toilet bowl has all the above advantages and is not described herein.

In an exemplary embodiment, the toilet seat 200 is provided with a flush port 2002 in communication with the basin 202, as shown in fig. 17 and 18. Flush port 2002 may take the form of a nipple that is mounted to a corresponding location on toilet seat 200 and interfaces with the first outlet of diverter valve 206 via tubing.

As shown in fig. 17, 18, 19 and 20, the toilet further includes: a diverter valve 206. The diverter valve 206 is provided with a water inlet, a first water outlet and a second water outlet. The first water outlet and the second water outlet are alternatively communicated with the water inlet. The water inlet is connected with a water source. The 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 in communication with the cleaning device 4 of the sewage system 100 to supply water to the cleaning device 4.

When the toilet needs to be flushed and discharged, the water inlet is communicated with the first water outlet, water enters the flushing port 2002 of the toilet after passing through the water dividing valve 206, then enters the toilet bowl 202, enters the sewage pipe 2 together with the sewage in the bowl 202, is discharged out of the sewage pipe 2 along with the downward rotation of the sewage pipe 2, enters the shifter 204 along with the sewage through the sewage outlet 14 of the sewage box 1, and finally enters an external sewage channel.

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

In addition, before flushing and draining the toilet, the water inlet and the first water outlet can be communicated, water enters the flushing port 2002 of the toilet after passing through the water diversion valve 206 and then enters the toilet bowl 202, so that the inner wall surface of the bowl 202 is wetted, dirt in the subsequent flushing and draining process can slide down in time, and the residual or suspended dirt on the inner wall surface of the bowl 202 is reduced.

Before the sewage discharge pipe 2 rotates to discharge sewage, the water inlet and the second water outlet can be communicated, so that water enters the cleaning device 4 after passing through the water dividing valve 206, is sprayed into the sewage discharge box 1 through the cleaning device 4, and wets the inner wall surface of the sewage discharge box 1, thereby being beneficial to timely sliding off of sewage in the subsequent flushing and sewage discharge process and reducing residual or suspended sewage on the inner wall surface of the sewage discharge box 1.

Thus, by controlling the selective conduction of the waterway inside the diverter valve 206, water can be supplied to 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 components and the length of pipelines of the closestool, thereby simplifying the structure of the closestool and reducing the product cost.

In an exemplary embodiment, the toilet seat 200 is provided with a plurality of water distribution ports that are provided on top of the basin 202. The water jet 2002 communicates with the basin 202 through a plurality of water distribution 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 water flushing port 2002, flows out of the water inlet channel through the water distribution ports into the basin 202, can clean and wet the inner wall surface of the basin 202, and can also raise the position of the water cover of the toilet, thereby increasing the gravitational potential energy of dirt and liquid in the sewage drain pipe 2.

Because the toilet bowl of the embodiment of the application mainly drives the sewage pipe 2 to rotate downwards to discharge sewage through the driving device 3, the principle is to realize falling sewage mainly by means of gravitational potential energy and falling inertia of sewage and liquid in the pipe, so that water provided by the water distribution port at the top of the basin 202 can play a role in improving sewage effect, and the bottom of the basin 202 is not required to be provided with an injection port so as to flush the sewage into the sewage pipe 2 by using large water flow of the injection port.

Therefore, the toilet bowl provided by the embodiment of the application can cancel the jet orifice at the bottom of the basin 202, only reserve the water diversion orifice at the top of the basin 202, and reduce noise on the premise of ensuring the pollution discharge effect, thereby being beneficial to improving the use experience of users.

Because the water flowing out of the water diversion port at the top of the basin 202 flows downwards along the inner wall surface of the basin 202, the water flow strength is relatively small, and the noise is also small; and the water flow of the jet orifice at the bottom of the basin 202 is large, so that the noise is also large.

It is worth to say that, in the existing water tank-free or water tank-containing toilet, the inner wall surface of the basin 202 is basically cleaned by water flowing out from the water diversion opening at the top of the basin 202, excrement is discharged by spraying water from the spraying opening at the bottom of the basin 202, and meanwhile, the siphon function is generated by utilizing the S-shaped bent pipeline of the ceramic base body, so that the sewage discharging function is realized. Because the sewage is mainly discharged by using the large water flow jet of the jet orifice to spray the excrement out of the S-shaped bent pipe, the use noise is high.

In the toilet bowl provided by the embodiment of the application, the toilet seat 200 only keeps the water diversion port (or the cleaning water spray port of the brush ring) at the top of the basin 202, and the jet port at the bottom of the basin 202 is omitted, so that the noise in the toilet bowl pollution discharge flushing process can be effectively reduced, and the use experience of a user is improved. And moreover, the driving device 3 controls the overturning of the sewage discharge pipe 2 to directly discharge sewage, the S-bend pipe of the existing siphon type closestool is canceled, the sewage discharge path can be shortened, the rapid sewage discharge function is realized, and the sewage discharge 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. 17 and 18. 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.

Thus, the on-off of the waterway in the toilet can be controlled by controlling the start and stop of the water pump 208; by controlling the shunt valve 206, the switching of the waterway in the shunt valve 206 can be controlled, thereby being beneficial to realizing automatic control.

In an exemplary embodiment, the toilet seat 200 is provided with a mounting cavity 2004, as shown in fig. 17 and 18, with the mounting cavity 2004 being located on the rear side of the basin 202. The sewage system 100, at least a portion of the diverter valve 206, at least a portion of the water storage tank 210, and the water pump 208 are located within the mounting cavity 2004.

Thus, compared with the scheme of arranging the water storage tank 210 above the toilet seat body 200, the toilet in the embodiment of the application has the advantages of compact overall structure and relatively small volume, is convenient to store and transport, can reduce the installation space of the toilet, and is beneficial to reducing the occupation of the toilet space.
