Detailed Description

[0011] Embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. The embodiments in the present disclosure and the features in the embodiments may be combined with each other arbitrarily if there is no conflict.

[0012] In an embodiment of the present disclosure, the up and down direction is based on the state of the toilet after it is assembled, the direction close to the ground is down, and the direction away from the ground is up.

[0013] As shown in FIG. 3, an embodiment of the present disclosure provides a sewage discharge box 1 applied to a toilet. The toilet also includes a sewage discharge pipe 2. The sewage discharge box 1 is provided with a rotary connecting hole 13, as shown in FIG. 3. The rotary connecting hole 13 is configured to be rotatably connected with the sewage discharge pipe 2. The sewage discharge pipe 2 is at least partially provided in the sewage discharge box 1 and rotates about the rotary connecting hole 13.

[0014] As shown in FIG. 12, a vertical plane where a central axis of the rotary connecting hole 13 is located is taken as an interface 15, an inner wall surface of the sewage discharge box 1 is divided into a sewage discharge area 11 and a non-sewage discharge area 12, and the sewage discharge pipe 2 rotates from a side where the non-sewage discharge area 12 is located to a side where the sewage discharge area 11 is located in a rotary sewage discharge process. In FIG. 12, a portion of the inner wall surface of the sewage discharge box 1 located in the left dashed box is the non-sewage discharge area 12. A portion of the inner wall surface of the sewage discharge box 1 located in the right box with thick dotted lines is the sewage discharge area 11.

[0015] As shown in FIG. 12, the non-sewage discharge area 12 and the sewage discharge area 11 are asymmetrically arranged with respect to the interface 15, and a space enclosed by the sewage discharge area 11 is larger than a space enclosed by the non-sewage discharge area 12.

[0016] A sewage discharge box 1 provided by an embodiment of the present disclosure is provided with a rotary connecting hole 13, and the rotary connecting hole 13 is configured to be rotatably connected with a sewage discharge pipe 2. A sewage inlet of the sewage discharge pipe 2 is communicated with a sewage discharge outlet 2006 of a bowl 202 of a toilet seat 200. A main body of the sewage discharge pipe 2 is located in the sewage discharge box 1 and can rotate from top to bottom in the sewage discharge box 1. When sewage is discharged, the sewage in the toilet bowl 202 enters the sewage discharge pipe 2, rotates downward with the sewage discharge pipe 2, discharges from the sewage discharge pipe 2 under the action of gravity, and discharges through a sewage outlet 14 of the sewage discharge box 1, as shown in FIGS. 7 to 9.

[0017] Since the sewage discharge pipe 2 only needs to rotate to one side in a rotary sewage discharge process, that is, to a side where the sewage discharge area 11 is located, as long as the side where the sewage discharge area 11 is located has sufficient space, the rotation demand of the sewage discharge pipe 2 can be satisfied, and a size of the space of the non-sewage discharge area 12 has no effect on the rotation demand of the sewage discharge pipe 2.

[0018] Based on this, a sewage discharge box 1 provided by an embodiment of the present disclosure adopts an irregular shape that is asymmetrically arranged, and the sewage discharge area 11 and the non-sewage discharge area 12 are designed to be asymmetrically arranged. Further, the space enclosed by the sewage discharge area 11 is relatively large to satisfy the rotation requirement of the sewage discharge pipe 2, while the space enclosed by the non-sewage discharge area 12 is relatively small. Compared with the prior art, the present scheme is equivalent to reducing the size of the non-sewage discharge area 12, so that the space enclosed by the non-sewage discharge area 12 is reduced, thereby reducing the volume of the sewage discharge box 1, reducing the demand for the assembly space of the sewage discharge box 1, and improving the adaptability and flexibility of the sewage discharge box 1.

[0019] In addition, the present scheme distributes the internal space of the sewage discharge box 1 mainly in the sewage discharge area 11, so that the internal space of the sewage discharge box 1 is mainly used for sewage discharge, thereby improving a space utilization rate in the sewage discharge box 1, increasing the available space for sewage discharge, and reducing the probability of blockage.

[0020] The sewage discharge pipe 2 may be completely located inside the sewage discharge box 1, the sewage discharge box 1 is fixedly connected to the toilet seat 200, and the sewage discharge pipe 2 is rotatably connected to the sewage discharge box 1. A sealing structure may be provided between connecting parts of the sewage discharge pipe 2 and the sewage discharge box 1, and a sealing structure may be provided between connecting parts of the sewage discharge box 1 and the toilet seat 200.

[0021] Alternatively, the sewage discharge pipe 2 may be partially located within the sewage discharge box 1. For example, the sewage discharge box 1 is fixedly connected to the toilet seat 200. The sewage inlet section of the sewage discharge pipe 2 can extend out of the sewage discharge box 1 through the rotary connecting hole 13, and is inserted into the sewage discharge outlet 2006 of the toilet seat 200 to realize communication with the sewage discharge outlet 2006. The sewage discharge pipe 2 can rotate relative to the toilet seat 200 and the sewage discharge box 1.

[0022] In addition, a connection part 23 of the sewage discharge pipe 2 for connecting with a drive device 3 may be located in the sewage discharge box 1 or may extend out of the sewage discharge box 1.

[0023] It should be noted that the sewage discharge pipe 2 rotates from a side where the non-sewage discharge area 12 is located to a side where the sewage discharge area 11 is located in a rotary sewage discharge process, and only a rotation direction (clockwise rotation or counterclockwise rotation) of the sewage discharge pipe 2 during the rotary sewage discharge process is limited, and an initial sewage discharge position of the sewage discharge pipe 2 is not limited. Since the sewage discharge pipe 2 needs to rotate from top to bottom in the rotary sewage discharge process in order to discharge the sewage in the pipe by gravity, a rotation direction of the sewage discharge pipe 2 can be determined based on the relative positions of the sewage discharge area 11 and the non-sewage discharge area 12. The initial sewage discharge position of the sewage discharge pipe 2 may be in a vertical state, as shown in FIG. 12, at this time a discharge outlet 21 of the sewage discharge pipe 2 may be partially located in the space at a side where the non-sewage discharge area 12 is located, and partially located in the space at a side where the sewage discharge area 11 is located. The initial sewage discharge position of the sewage discharge pipe 2 may also be slightly inclined, and at this time the discharge outlet 21 of the sewage discharge pipe 2 may be completely located in the space at a side where the sewage discharge area 11 is located.

[0024] In an exemplary embodiment, the sewage discharge box 1 includes a box main body 17 and a box cover 16, as shown in FIG. 11. The box main body 17 is provided with a rotary connecting hole 13. The box cover 16 is in a closed connection with the box main body 17, and a sealing ring 18 may be provided between the box cover 16 and the box main body 17, as shown in FIG. 23. The box cover 16 is provided with a connecting hole 161, as shown in FIG. 23. As shown in FIG. 3, the sewage discharge pipe 2 is provided with a connecting part 23, and the drive device 3 is connected to the connecting part 23 through the connecting hole 161 to drive the sewage discharge pipe 2 to rotate.

[0025] The box main body 17 is provided on a front side of the box cover 16, and both the box main body 17 and the box cover 16 have irregular shapes in the left and right direction.

[0026] The sewage discharge box 1 is sectioned in a vertical direction perpendicular to an interface 15, and a contour line of an inner wall surface of the sewage discharge box 1 is an irregular shape arranged asymmetrically. The sewage discharge box 1 is cut along the interface 15, and the contour line of the inner wall surface of the sewage discharge box 1 is substantially rectangular or rounded rectangular. When the sewage discharge box 1 is cut in a horizontal direction perpendicular to the interface 15, the contour line of the inner wall surface of the sewage discharge box 1 is also substantially rectangular or rounded rectangular.

[0027] Therefore, an irregular shape of the sewage discharge box 1 can be seen clearly and intuitively from the front and rear direction in the figures.

[0028] Of course, the outer wall surface of the sewage discharge box 1 may also include some other structures, such as a connection lug, the connecting hole 161, and the like, for realizing the installation and fixation of the sewage discharge box 1, and the installation and fixation of the sewage discharge box 1 and the drive device 3.

[0029] In an exemplary embodiment, a width L1 of the sewage discharge area 11 in a horizontal direction perpendicular to the interface 15 is greater than a width L2 of the non-sewage discharge area 12 in the horizontal direction perpendicular to the interface 15, as shown in FIG. 12.

[0030] A width of the sewage discharge area 11 in the horizontal direction perpendicular to the interface 15 needs to be greater than a distance between the discharge outlet 21 of the sewage discharge pipe 2 and a rotation axis of the sewage discharge pipe 2 (i.e., a central axis of the rotary connecting hole 13), so as to ensure that the sewage discharge pipe 2 does not interfere with the inner wall surface of the sewage discharge box 1 when rotated to the horizontal direction. A width of the non-sewage discharge area 12 in the horizontal direction perpendicular to the interface 15 is not limited by this limitation, and therefore can be designed to be relatively small to reduce the volume of the sewage discharge box 1.

[0031] In this way, the sewage discharge box 1 has an eccentric design as a whole, that is, the central axis of the rotary connecting hole 13 is closer to the side where the non-sewage discharge area 12 is located in the horizontal width direction of the sewage discharge box 1 (i.e., the left and right direction in the figures), instead of being located at the central position in the horizontal width direction of the sewage discharge box 1. It not only satisfies the need for the sewage discharge pipe 2 to rotate unilaterally, but also reduces the volume of the sewage discharge box 1, thereby improving the flexibility and adaptability of the sewage discharge system 100.

[0032] In an exemplary embodiment, the sewage discharge area 11 includes a transition area 111, as shown in FIG. 14. As shown in FIGS. 7 to 9, the transition area 111 is configured such that during the rotation of the sewage discharge pipe 2 relative to the sewage discharge box 1, the discharge outlet 21 of the sewage discharge pipe 2 faces the transition area 111.

[0033] A distance between the central axis of the rotary connecting hole 13 and the transition area 111 is gradually increased in a direction from top to bottom.

[0034] In the rotation and sewage discharge process of the sewage discharge pipe 2, as the sewage discharge pipe 2 rotates from top to bottom, the sewage in the sewage discharge pipe 2 is gradually discharged, and the discharge speed becomes faster and faster, and the throwing distance becomes farther and farther. Therefore, when the distance between the central axis of the rotary connecting hole 13 and the transition area 111 is gradually increased in the direction from top to bottom, a distance between the discharge outlet 21 of the sewage discharge pipe 2 and the inner wall surface of the sewage discharge box 1 is also gradually increased during the rotary sewage discharge process. It is conducive to reducing the probability that the sewage discharged from the sewage discharge pipe 2 is thrown on the inner wall surface of the sewage discharge box 1, so that the sewage directly falls with less contact or even no contact with the inner wall surface of the sewage discharge box 1, thereby helping to reduce the sewage remaining or hanging on the inner wall surface of the sewage discharge box 1, helping to improve the cleanliness and hygiene of the sewage discharge box 1, and helping to improve the sensory perception of the user.

[0035] In an exemplary embodiment, the sewage discharge area 11 also includes an outlet area 112 located below the rotary connecting hole 13, as shown in FIG. 14. The outlet area 112 defines a sewage outlet 14 of the sewage discharge box 1, and a central axis of the sewage outlet 14 offsets from the interface 15.

[0036] According to the present scheme, the sewage outlet 14 of the sewage discharge box 1 is provided at a lower part of the sewage discharge area 11, so that the central axis of the sewage outlet 14 offsets from the interface 15, and the sewage outlet 14 of the sewage discharge box 1 and the rotary connecting hole 13 (equivalent to the sewage inlet of the sewage discharge box 1) are arranged in a misaligned and eccentric layout in a horizontal width direction (left and right direction in the figures), that is, the sewage outlet 14 is not located directly below the rotary connecting hole 13, but is located obliquely below the rotary connecting hole 13.

[0037] In contrast to arranging the sewage outlet 14 directly below the central axis of the rotary connecting hole 13, the misaligned and eccentric layout design of the present scheme is conducive to reducing a distance between the discharge outlet 21 (as shown in FIG. 7, at the highest position) of the sewage discharge pipe 2 and the sewage outlet 14 of the sewage discharge box 1, thereby shortening the rotation angle of the sewage discharge pipe 2 when it rotates from the initial position to the sewage discharge position, so as to achieve the purpose of rapid sewage discharge.

[0038] In addition, in contrast to arranging the sewage outlet 14 directly below the central axis of the rotary connecting hole 13 (as shown in FIG. 13), the present scheme adopts a misaligned and eccentric layout design, which can reduce the space occupied by an area of the sewage discharge box 1 directly below the central axis of the rotary connecting hole 13, thereby further reducing the volume of the sewage discharge box 1, and is conducive to further improving the flexibility and adaptability of the sewage discharge box 1.

[0039] In an exemplary embodiment, a longitudinal cross section perpendicular to the interface 15 is referred to as a longitudinal perpendicular section, that is, a cross section obtained by sectioning the sewage discharge box 1 in a vertical direction perpendicular to the interface 15. A contour line of the transition area 111 in the longitudinal perpendicular section includes a first section 1111, a second section 1112, and a third section 1113 sequentially connected from top to bottom, as shown in FIGS. 14 and 15. An area corresponding to the third section 1113 is configured to directly face the discharge outlet 21 of the sewage discharge pipe 2 when the sewage discharge pipe 2 is rotated to the sewage discharge position, as shown in FIG. 9.

[0040] The third section 1113 is provided as an inclined straight section and extends downward at an angle in a direction close to the non-sewage discharge area 12, as shown in FIG. 14.

[0041] When the sewage discharge pipe 2 is rotated to a sewage discharge position, a large amount of sewage in the sewage discharge pipe 2 is discharged outward. Since the discharge outlet 21 of the sewage discharge pipe 2 at this time directly faces the region corresponding to the third section 1113 of the transition area 111, a large amount of sewage may come into contact with the region, as shown in FIG. 9, and then fall along the region. Compared with an arc section (e.g., a dotted arc section in a comparative example illustrated in FIG. 15), the third section 1113 is provided as an inclined straight section in the present scheme, and the straight section is shorter than the arc section, which can reduce an area of the region corresponding to the third section 1113 so as to facilitate the sewage to quickly leave the region, and can also make the region have a larger inclination angle so as to facilitate the efficient and rapid sliding of sewage, thereby achieving a more efficient sewage discharge and sliding effect.

[0042] In other words, the region corresponding to the third section 1113 forms a guide sewage discharge surface, which can play an efficient guide sewage discharge effect, as shown in FIG. 9.

[0043] In an exemplary embodiment, the first section 1111 is provided in an arc shape and the second section 1112 extends in a vertical direction, as shown in FIGS. 14 and 15.

[0044] In the present scheme, the first section 1111 is provided as an arc section and the second section 1112 is provided as a vertical straight section, a region corresponding to the first section 1111 is a circular arc surface, and a region corresponding to the second section 1112 is an upright plane (that is, a plane perpendicular to a horizontal plane, or called a vertical plane). Compared with designing the first section 1111 and the second section 1112 as a complete arc section, the present scheme reduces the length of the second section 1112, so that the area of the region corresponding to the second section 1112 can be reduced, which helps to improve the sewage discharge efficiency.

[0045] Moreover, compared with the arc surface, the upright plane is less likely to hang sewage, and the hanging sewage is more likely to slip. In addition, compared with the arc surface, the upright plane can reduce a width of the sewage discharge area 11 in the horizontal direction perpendicular to the interface 15 (that is, the width in the left and right direction in the figures), which takes up less outside space, thereby helping to further reduce the volume of the sewage discharge box 1, and further improving the flexibility and adaptability of the sewage discharge box 1.

[0046] As a comparative example, the second section 1112 is designed as an arc section concentric to the first section 1111, such as the dotted arc section in the comparative example illustrated in FIG. 15. It is calculated that a length of the second section 1112 in the comparative example will increase by about 6%.

[0047] In an exemplary embodiment, as shown in FIG. 14, a contour line of the outlet area 112 in the longitudinal perpendicular section includes a fourth section 1121 and a fifth section 1122. The fourth section 1121 is smoothly connected to the lower end of the third section 1113, so that the sewage on a region corresponding to the third section 1113 can smoothly slide into the sewage outlet 14 and discharge, which is conducive to improving the sewage discharge efficiency. The fifth section 1122 is configured to be spaced from the fourth section 1121, and the sewage outlet 14 is formed between the fifth section 1122 and the fourth section 1121.

[0048] 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 arranged opposite the fourth section 1121, and the sewage outlet 14 is formed between the outlet section 1123 and the fourth section 1121. The dumping surface 22 of the sewage discharge pipe 2 is provided with a flaring part in a sewage discharge dumping direction, as shown in FIGS. 9 and 10.

[0049] As shown in FIG. 10, the outlet section 1123 is configured such that when the sewage discharge pipe 2 is rotated to a sewage discharge position, the outlet section 1123 is adapted to a contour line of the dumping surface 22 of the sewage discharge pipe 2 in a longitudinal perpendicular section, so that the outlet section 1123 forms a flaring guide part for guiding the discharge of sewage. The dumping surface 22 of the sewage discharge pipe 2 refers to a lower part of an inner side wall of the sewage discharge pipe 2 when the sewage discharge pipe 2 is in the sewage discharge position, and the sewage in the sewage discharge pipe 2 is discharged downward along the part of the inner side wall.

[0050] A lower end of the transition section 1124 is smoothly connected to the upper end of the outlet section 1123, and an upper end of the transition section 1124 is smoothly connected to a contour line of the non-sewage discharge area 12 in the longitudinal perpendicular section.

[0051] In the present scheme, when the sewage discharge pipe 2 is in the sewage discharge position, a region corresponding to the outlet section 1123 is located on an extended surface of the dumping surface 22 of the sewage discharge pipe 2, and is adapted to a shape of the dumping surface 22 of the sewage discharge pipe 2, so that the region corresponding to the outlet section 1123 forms a flaring guide part, which can play a better guiding role for the sewage, and is beneficial for the sewage to enter the sewage outlet 14 of the sewage discharge box 1 quickly, smoothly and efficiently along the part.

[0052] However, a region corresponding to the transition section 1124 has a negligible effect on the discharge of sewage, so that the position of the transition section 1124 can be properly raised and smoothly connected with the non-sewage discharge area 12, so as to further reduce the volume of the sewage discharge box 1.

[0053] In an example, the outlet section 1123 has a circular arc shape, which facilitates smooth slipping of sewage along the region corresponding to the outlet section 1123.

[0054] In an exemplary embodiment, as shown in FIG. 14, a contour line of the non-sewage discharge area 12 in the longitudinal perpendicular section includes a sixth section 121, a seventh section 122, and an eighth section 123 sequentially connected from top to bottom.

[0055] The sixth section 121 is smoothly connected with the first section 1111. The eighth section 123 is smoothly connected with a contour line of the outlet area 112 in the longitudinal perpendicular section.

[0056] For example, as shown in FIG. 14, the sixth section 121 is provided in an arc shape, and a center of the sixth section is the same as that of the first section 1111. The seventh section 122 extends in a vertical direction, as shown in FIG. 15.

[0057] In this way, the sixth section 121 and the first section 1111 form a continuous arc, so that the shape of the part forms a regular arc surface, which is convenient for machining and shaping. The seventh section 122 is provided as a vertical straight section. Compared with the arc section configured to be concentric with the sixth section 121, the straight section has a shorter length, and a distance between the straight section and the central axis of the rotary connecting hole 13 is smaller. Therefore, it is advantageous to reduce a width of the non-sewage discharge area 12 in a horizontal direction perpendicular to the interface 15 (i.e., a width in the left and right direction in the figures), and to further reduce the volume of the sewage discharge box 1.

[0058] As a comparative example, the sewage discharge box 1 is designed to have a regular shape, such as a structure illustrated by the dashed line in FIG. 16. A contour line of an inner wall surface of the sewage discharge box 1 in the longitudinal perpendicular section is a regular circle, and the contour line is a complete circle formed by the extension of the first section 1111 and the sixth section 121.

[0059] Through calculation, it is known that an embodiment of the present disclosure adopts a special-shaped design in which the left and right sides are asymmetrically arranged, so that the inner wall surface of the sewage discharge box 1 can be reduced by about 34% in terms of area (area of the longitudinal perpendicular section) and overall volume, that is, the volume is reduced by more than 1/3, and the occupation of the sewage discharge box 1 on an inner space of the toilet is greatly saved.

[0060] Therefore, a shape of a sewage discharge box 1 provided by an embodiment of the present disclosure is optimized, the volume of the sewage discharge box 1 is effectively reduced, and the adaptability of the sewage discharge system 100 is greatly improved.

[0061] In an exemplary embodiment, an upper end of the seventh section 122 is higher than an upper end of the second section 1112, and a lower end of the seventh section 122 is higher than a lower end of the second section 1112, as shown in FIG. 14.

[0062] Thus, the position of the seventh section 122 is relatively high, and a distance between the seventh section 122 and the interface 15 is relatively small, which is conducive to further reducing the volume of the sewage discharge box 1. The position of the second section 1112 is relatively low, and a distance between the second section 1112 and the interface 15 is relatively large, which is conducive to avoiding interference between the sewage discharge area 11 and the sewage discharge pipe 2 or contact with excessive sewage.

[0063] In an exemplary embodiment, as shown in FIG. 9, the space enclosed by the sewage discharge area 11 is configured such that the maximum rotary angle α provided for the sewage discharge pipe 2 is in the range of 100° to 120°.

[0064] In other words, due to a shape of the sewage discharge area 11, the sewage discharge pipe 2 can rotate only 100° to 120° in the sewage discharge box 1, and if the sewage discharge pipe 2 continues to rotate, it interferes with the sewage discharge box 1.

[0065] Compared with the scheme in which the sewage discharge pipe 2 rotates 180° (from vertical upward to vertical downward), in this scheme, the sewage discharge pipe 2 only needs to rotate 100° to 120°, which reduces the rotation time and is conducive to improving the sewage discharge efficiency. Moreover, the present scheme also reduces the volume of the sewage discharge box 1, and is conducive to improving the flexibility and adaptability of the sewage discharge box 1.

[0066] As shown in FIGS. 11, 12, and 14, an embodiment of the present disclosure also provides a sewage discharge system 100 including a sewage discharge box 1 in any one of the above embodiments, a sewage discharge pipe 2, and a drive device 3. The sewage discharge pipe 2 is rotatably connected to the sewage discharge box 1. The drive device 3 is connected to the sewage discharge pipe 2 and is configured to drive the sewage discharge pipe 2 to rotate relative to the sewage discharge box 1.

[0067] Since a sewage discharge system 100 provided by an embodiment of the present disclosure includes the sewage discharge box 1 according to any one of the above embodiments, it has all the beneficial effects of any of the above embodiments, which will not be described here in detail.

[0068] In an exemplary embodiment, the sewage discharge box 1 includes a box main body 17 and a box cover 16, as shown in FIG. 11. The box main body 17 is provided with a rotary connecting hole 13, as shown in FIG. 3. The box cover 16 is in closed connection with the box main body 17. A sealing ring 18 is provided between the box cover 16 and the box main body 17, and a sealing member 19 is provided between the sewage discharge pipe 2 and the sewage discharge box 1, as shown in FIG. 23. The box cover 16 is provided with a connecting hole 161, and the sewage discharge pipe 2 is provided with a connecting part 23. The drive device 3 is connected to the connecting part 23 through the connecting hole 161, and is configured to drive the sewage discharge pipe 2 to rotate. The drive device 3 may be a motor.

[0069] A sewage discharge principle of the sewage discharge system 100 is as follows (as shown in FIGS. 7 to 9).

[0070] When sewage is discharged by rotation, the sewage in the bowl 202 of the toilet seat 200 enters the sewage discharge pipe 2, and the sewage discharge pipe 2 is driven by the drive device 3 to rotate by 100° to 120° to the right from an initial position (that is, the discharge outlet 21 is facing upwards, as shown in FIG. 7) to reach a sewage discharge position (as shown in FIG. 9). The sewage is discharged from the discharge outlet 21 through the sewage outlet 14 of the sewage discharge box 1.

[0071] After the sewage discharge action is completed, the sewage discharged through the sewage discharge pipe 2 flows into a shifter 204 through the sewage outlet 14 of the sewage discharge box 1 and is introduced into the external sewage discharge channel. A sealing ring 18 is provided between the shifter 204 and the sewage discharge box 1. The sewage discharge pipe 2 is reset to the initial position (as shown in FIG. 7) under the driving of the drive device 3, and is reapplied for the next sewage discharge function.

[0072] In an exemplary embodiment, the sewage discharge system 100 also includes a cleaning device 4, as shown in FIGS. 18 and 23. The cleaning device 4 is connected to the sewage discharge box 1 and is configured to spray cleaning liquid into the inside of the sewage discharge box 1, so that the cleaning device 4 can play a cleaning role on the sewage discharge box 1, and is conducive to discharging residual or hanging sewage in the sewage discharge box 1, thereby improving the cleanliness of the sewage discharge box 1 and maintaining a good sewage discharge effect.

[0073] In an exemplary embodiment, as shown in FIG. 23, the cleaning device 4 includes a liquid inlet pipe 41 and a spraying member 42. The liquid inlet pipe 41 is communicated with the sewage discharge box 1. The spraying member 42 is connected to the liquid inlet pipe 41 and is configured to spray a cleaning liquid into the sewage discharge box 1.

[0074] In this way, the liquid inlet pipe 41 can communicate with an external cleaning source (such as an external water source), introduce a cleaning liquid into the sewage discharge box 1, and spray the cleaning liquid into the sewage discharge box 1 by the spraying member 42, thereby performing a cleaning function on the sewage discharge box 1, and facilitating the discharge of residual or hanging sewage in the sewage discharge box 1, thus improving the cleanliness of the sewage discharge box 1 and maintaining a good sewage discharge effect.

[0075] As shown in FIGS. 1 to 9 and 17 to 22, an embodiment of the present disclosure also provides a toilet, including a toilet seat 200 and a sewage discharge system 100 in the above-described embodiment.

[0076] As shown in FIGS. 17 to 20, the toilet seat 200 is provided with a bowl 202, and the bowl 202 is provided with a sewage discharge outlet 2006. The sewage discharge pipe 2 of the sewage discharge system 100 is communicated with the sewage discharge outlet 2006, and a central axis of the sewage discharge outlet 2006 is collinear with a rotation axis of the sewage discharge pipe 2.

[0077] A toilet provided by an embodiment of the present disclosure has all the above-mentioned beneficial effects because it includes the sewage discharge system 100 in the above-mentioned embodiment, which will not be described here in detail.

[0078] In an exemplary embodiment, the toilet seat 200 is provided with a flush port 2002 communicating with the bowl 202, as shown in FIGS. 17 and 18. The flush port 2002 may be in the form of a pipe joint, which is mounted at a corresponding position on the toilet seat 200, and is connected to a first water outlet of the water diverter valve 206 by a pipeline.

[0079] As shown in FIGS. 17, 18, 19, and 20, the toilet also includes a water diverter valve 206. The water diverter 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 connected with the water inlet. The water inlet is configured to connect to the water source. The first water outlet is configured to be communicated with the flush port 2002 to supply water to the bowl 202. The second water outlet is configured to be communicated with the cleaning device 4 of the sewage discharge system 100 to supply water to the cleaning device 4.

[0080] When the toilet needs to be flushed and discharged, the water inlet is communicated with the first water outlet, the water passes through the water diverter valve 206, enters the flush port 2002 of the toilet, and then enters the toilet bowl 202, enters the sewage discharge pipe 2 together with the sewage in the bowl 202, rotates downward with the sewage discharge pipe 2 to discharge from the sewage discharge pipe 2, enters the shifter 204 with the sewage through the sewage outlet 14 of the sewage discharge box 1, and finally enters the external sewage discharge channel.

[0081] When the flushing and discharging is completed, the water diverter valve 206 can be switched to another waterway to communicate the water inlet with the second water outlet, and the water enters the cleaning device 4 after passing through the water diverter valve 206, and is sprayed into the inside of the sewage discharge box 1 through the cleaning device 4 to clean the inside of the sewage discharge box 1, thereby improving the cleanliness of the sewage discharge box 1 and enabling the sewage discharge system 100 to maintain a good sewage discharge effect.

[0082] In addition, before the toilet is flushed and discharged, the water inlet can be communicated with the first water outlet, and the water enters the flush port 2002 of the toilet after passing through the water diverter valve 206, and then enters the bowl 202 of the toilet, so that an inner wall surface of the bowl 202 is wetted, which is conducive to the timely slipping of the sewage during the subsequent flush and discharge process, and reduces the sewage remaining or hanging on the inner wall surface of the bowl 202.

[0083] Before the sewage discharge pipe 2 rotates to discharge sewage, the water inlet can also be communicated with the second water outlet, so that the water enters the cleaning device 4 after passing through the water diverter valve 206, and is sprayed into the interior of the sewage discharge box 1 through the cleaning device 4, so that the inner wall surface of the sewage discharge box 1 is wetted, which is conducive to the timely slipping of the sewage during the subsequent flush and discharge process, and reduces the sewage remaining or hanging on the inner wall surface of the sewage discharge box 1.

[0084] In this way, by controlling the selective communication of the internal waterway of the water diverter valve 206, water supply for different functions of the toilet can be provided. Compared with a scheme in which a plurality of water valves are respectively connected with a flush port 2002 and a cleaning device 4, the present scheme is conducive to reducing the number of components and the length of the pipeline of the toilet, thereby simplifying the structure of the toilet and reducing the product cost.

[0085] In an exemplary embodiment, the toilet seat 200 is provided with a plurality of water diverter ports, and the plurality of water diverter ports are provided at the top of the bowl 202. The flush port 2002 communicates with the bowl 202 through the plurality of water diverter ports.

[0086] In other words, a water inlet passage is provided at the top of the toilet seat 200, and water enters the water inlet passage through the flush port 2002, and flows out of the water inlet passage through the plurality of water diverter ports and into the bowl 202, so that the inner wall surface of the bowl 202 can be cleaned and wetted, and the position of the bowl water level of the toilet can be raised, thereby increasing the gravitational potential energy of the sewage and liquid in the sewage discharge pipe 2.

[0087] Since a toilet according to an embodiment of the present disclosure mainly drives the sewage discharge pipe 2 by the drive device 3 to rotate downward so as to discharge the sewage, the principle is mainly to realize the falling sewage discharge by relying on the gravitational potential energy and falling inertia of the sewage and liquid in the pipe, so that the water provided by the water diverter ports on the top of the bowl 202 can play a role in improving the sewage discharge effect, and there is no need to provide an injection port at the bottom of the bowl 202 to flush the sewage into the sewage discharge pipe 2 by using the large water flow of the injection port.

[0088] Therefore, in a toilet provided by an embodiment of the present disclosure, the injection port at the bottom of the bowl 202 can be omitted, and only the water diverter ports at the top of the bowl 202 can be retained, such that the noise can be reduced on the premise of ensuring the sewage discharge effect, thereby helping to improve the user experience.

[0089] Since the water flowing out of the water diverter ports at the top of the bowl 202 flows downward along an inner wall surface of the bowl 202, the water flow intensity is relatively small, and the noise is also lower. The water flow at the injection port at the bottom of the bowl 202 is large, and the noise is also higher.

[0090] It is worth noting that the existing toilets without a water tank or with a water tank basically clean the inner wall surface of the bowl 202 through the water flowing out of the water diverter port at the top of the bowl 202, exclude excrement through the water sprayed from the injection port at the bottom of the bowl 202, and use the S-bend pipeline of the ceramic seat itself to generate a siphon function so as to realize a sewage discharge function. Because the sewage discharge mainly uses the large water flow of an injection port to spray the excrement into the S-bend pipe, the noise is loud when used.

[0091] For a toilet provided by an embodiment of the present disclosure, the toilet seat 200 only retains the water diverter ports (or called the cleaning water spray ports of the rim) at the top of the bowl 202, and the injection port at the bottom of the bowl 202 is omitted, so that the noise during a toilet sewage discharge and flush process can be effectively reduced, and the user experience can be improved. Moreover, the drive device 3 controls the turnover of the sewage discharge pipe 2 to directly discharge the sewage, and the S-bend pipe of the existing siphon toilet is canceled, so that the sewage discharge path can be shortened, the rapid sewage discharge function can be realized, and the sewage discharge effect is good.

[0092] In an exemplary embodiment, the toilet also includes a water storage tank 210 and a water pump 208, as shown in FIGS. 17 and 18. An input end of the water pump 208 is communicated with the water storage tank 210. An output end of the water pump 208 is communicated with the water inlet and configured to pump the water in the water storage tank 210 into the water diverter valve 206.

[0093] In this way, by controlling the start-stop of the water pump 208, the on-off of the waterway in the toilet can be controlled. By controlling the water diverter valve 206, the switching of the water channel in the water diverter valve 206 can be controlled, thereby facilitating the realization of automatic control.

[0094] In an exemplary embodiment, the toilet seat 200 is provided with a mounting cavity 2004 located on a rear side of the bowl 202, as shown in FIGS. 17 and 18. The sewage discharge system 100, at least a portion of the water 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.

[0095] In this way, compared with the scheme in which the water storage tank 210 is arranged above the toilet seat 200, a toilet of the embodiments of the present disclosure has a compact overall structure and a relatively small volume, which is convenient for storage and transportation and can also reduce the installation space of the toilet, and is conducive to reducing the occupation of the bathroom space.
