[0010] The following describes in detail the embodiments of the present disclosure with reference to the drawings. The embodiments and features of the embodiments of the present disclosure may be arbitrarily combined unless they conflict with each other.

[0011] In the embodiment of the present disclosure, the up and down directions are based on the state in which the toilet is fully assembled, with the direction closer to the ground being down and the direction farther from the ground being up.

[0012] As shown in Fig. 3, an embodiment of the present disclosure provides a waste discharge box 1 applied to a toilet. The toilet further includes a waste discharge pipe 2. As shown in Fig. 3, the waste discharge box 1 is provided with a rotary connection hole 13. The rotary connection hole 13 is configured to be rotatably connected to the waste discharge pipe 2. The waste discharge pipe 2 is at least partially disposed in the waste discharge box 1 and rotates around the rotary connection hole 13.

[0013] 12, the vertical plane on which the central axis of the rotary connection hole 13 is located is used as boundary plane 15 to divide the inner wall surface of the waste discharge box 1 into a waste discharge area 11 and a non-waste discharge area 12, and in the process of rotating and discharging waste, the waste discharge pipe 2 rotates from the non-waste discharge area 12 side to the side where the waste discharge area 11 is located. In FIG. 12, the part of the inner wall surface of the waste discharge box 1 located within the thin dashed line block on the left side is the non-waste discharge area 12, and the part of the inner wall surface of the waste discharge box 1 located within the thick dashed line block on the right side is the waste discharge area 11.

[0014] As shown in FIG. 12, the non-waste discharge area 12 and the waste discharge area 11 are arranged asymmetrically with respect to the boundary surface 15, and the space surrounded by the waste discharge area 11 is larger than the space surrounded by the non-waste discharge area 12.

[0015] The waste discharge box 1 according to the embodiment of the present disclosure is provided with a rotating connection hole 13, which is configured to be rotatably connected to the waste discharge pipe 2. The waste inlet of the waste discharge pipe 2 is communicated with the waste discharge outlet 2006 of the bowl 202 of the toilet body 200. The body of the waste discharge pipe 2 is located in the waste discharge box 1, and can rotate from top to bottom within the waste discharge box 1. As shown in Figures 7 to 9, when discharging waste, the waste in the toilet bowl 202 enters the waste discharge pipe 2, and as the waste discharge pipe 2 rotates downward, it is discharged from the waste discharge pipe 2 by gravity and is discharged through the waste outlet 14 of the waste discharge box 1.

[0016] In the process of rotating to discharge sewage, the sewage discharge pipe 2 only needs to rotate in one direction, i.e., to the side where the sewage discharge area 11 is located, and therefore, it is sufficient that there is sufficient space on the side where the sewage discharge area 11 is located to meet the rotation demand of the sewage discharge pipe 2, and the space size of the non-sewage discharge area 12 does not affect the rotation demand of the sewage discharge pipe 2.

[0017] Based on this, the waste discharge box 1 according to the embodiment of the present disclosure adopts an irregular shape with an asymmetrical arrangement, and the waste discharge area 11 and the non-waste discharge area 12 are designed to have an asymmetrical arrangement shape. Then, the space surrounded by the waste discharge area 11 is relatively large, while the space surrounded by the non-waste discharge area 12 is relatively small, so as to meet the rotation demand of the waste discharge pipe 2. Compared with the prior art, this proposal corresponds to reducing the size of the non-waste discharge area 12 and decreasing the space surrounded by the non-waste discharge area 12, thus reducing the volume of the waste discharge box 1, lowering the requirement for the assembly space of the waste discharge box 1, and favoring improving the adaptability and flexibility of the waste discharge box 1.

[0018] In addition, the present invention distributes the internal space of the sewage discharge box 1 mainly to the sewage discharge area 11, and uses the internal space of the sewage discharge box 1 mainly for discharging sewage, which is advantageous in increasing the space utilization rate within the sewage discharge box 1, increasing the available space for sewage discharge, and reducing the probability of clogging.

[0019] The waste discharge pipe 2 may be located completely inside the waste discharge box 1, in which case the waste discharge box 1 and the toilet body 200 are fixedly connected, and the waste discharge pipe 2 and the waste discharge box 1 are rotatably connected, and a seal structure may be provided at the connection portion between the waste discharge pipe 2 and the waste discharge box 1, and a seal structure may also be provided at the connection portion between the waste discharge box 1 and the toilet body 200.

[0020] Or, the waste discharge pipe 2 may be partially located within the waste discharge box 1. For example, the waste discharge box 1 is fixedly connected to the toilet body 200. The waste entry segment of the waste discharge pipe 2 may protrude from the waste discharge box 1 through the rotating connection hole 13 and be inserted into the waste discharge port 2006 of the toilet body 200 to achieve communication with the waste discharge port 2006. And the waste discharge pipe 2 may rotate relative to the toilet body 200 and the waste discharge box 1.

[0021] Furthermore, the connection portion 23 of the waste discharge pipe 2 for connecting with the drive device 3 may be located inside the waste discharge box 1 or may protrude outside the waste discharge box 1.

[0022] Incidentally, the rotation of the sewage discharge pipe 2 from the non-sewage discharge area 12 side to the side where the sewage discharge area 11 is located in the process of rotating to discharge sewage is a limitation on the rotation direction (clockwise or counterclockwise) in the process of rotating to discharge sewage, and does not limit the initial sewage discharge position of the sewage discharge pipe 2. In the process of rotating to discharge sewage, the sewage discharge pipe 2 needs to rotate from top to bottom in order to discharge the sewage in the pipe by using gravity, and therefore the 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. On the other hand, the initial sewage discharge position of the sewage discharge pipe 2 may be vertical, and as shown in FIG. 12, in this case, the sewage discharge outlet 21 of the sewage discharge pipe 2 may be partially located in the space on the non-sewage discharge area 12 side and partially located in the space on the sewage discharge area 11 side, and the initial sewage discharge position of the sewage discharge pipe 2 may also be slightly inclined, and in this case, the sewage discharge outlet 21 of the sewage discharge pipe 2 may be completely located in the space on the sewage discharge area 11 side.

[0023] In one exemplary embodiment, as shown in FIG. 11, the waste discharge box 1 includes a box body 17 and a box cover 16. The box body 17 is provided with a rotation connection hole 13. As shown in FIG. 23, the box cover 16 and the box body 17 are cover-connected, and a seal ring 18 may be provided between the box cover 16 and the box body 17. As shown in FIG. 23, the box cover 16 is provided with a connection hole 161. The waste discharge pipe 2 is provided with a connection part 23, and as shown in FIG. 3, the driving device 3 is connected to the connection part 23 through the connection hole 161, thereby driving the waste discharge pipe 2 to rotate.

[0024] The box body 17 is provided in front of the box cover 16, and both the box body 17 and the box cover 16 have irregular shapes in the left-right direction.

[0025] When the waste discharge box 1 is cut along a vertical direction perpendicular to the boundary surface 15, the contour line of the inner wall surface of the waste discharge box 1 has an asymmetrically arranged irregular shape. When the waste discharge box 1 is cut along the boundary surface 15, the contour line of the inner wall surface of the waste discharge box 1 forms an approximate rectangle or a rectangle with rounded corners. When the waste discharge box 1 is cut along a horizontal direction perpendicular to the boundary surface 15, the contour line of the inner wall surface of the waste discharge box 1 also forms an approximate rectangle or a rectangle with rounded corners.

[0026] Therefore, the irregularity in the shape of the waste discharge box 1 is clearly and intuitively visible from the front-to-back direction in the figure.

[0027] Of course, the outer wall surface of the waste discharge box 1 may further include some other structures, such as connecting lugs, connecting holes 161, etc., which are used to realize the installation and fixing of the waste discharge box 1 and the installation and fixing of the waste discharge box 1 and the driving device 3.

[0028] In one exemplary embodiment, as shown in FIG. 12, the width L1 of the waste discharge area 11 in the horizontal direction perpendicular to the boundary surface 15 is greater than the width L2 of the non-waste discharge area 12 in the horizontal direction perpendicular to the boundary surface 15.

[0029] The width of the waste discharge area 11 in the horizontal direction perpendicular to the boundary surface 15 must be greater than the distance between the waste discharge port 21 of the waste discharge pipe 2 and the rotation axis of the waste discharge pipe 2 (i.e., the central axis of the rotary connection hole 13), thereby ensuring that the waste discharge pipe 2 does not interfere with the inner wall surface of the waste discharge box 1 when rotating in the horizontal direction. Meanwhile, the width of the non-waste discharge area 12 in the horizontal direction perpendicular to the boundary surface 15 is not limited thereto, and may be designed to be smaller in order to reduce the volume of the waste discharge box 1.

[0030] In this way, an eccentric design is formed throughout the sewage discharge box 1, that is, the central axis of the rotating connection hole 13 is eccentric to the side where the non-sewage discharge area 12 is located, rather than being at the center of the horizontal width of the sewage discharge box 1 in the horizontal width direction (i.e., the left and right direction in the figure), thereby meeting the requirement for one-sided rotation of the sewage discharge pipe 2 and reducing the volume of the sewage discharge box 1, thereby improving the flexibility and adaptability of the sewage discharge system 100.

[0031] In one exemplary embodiment, the waste discharge area 11 includes a transition area 111, as shown in Fig. 14. The transition area 111 is configured such that the waste discharge outlet 21 of the waste discharge pipe 2 faces the transition area 111 in the process of the waste discharge pipe 2 rotating relative to the waste discharge box 1, as shown in Figs. 7 to 9.

[0032] The distance between the central axis of the rotary connecting hole 13 and the transition area 111 gradually increases along the top-to-bottom direction.

[0033] In the process of the sewage discharge pipe 2 rotating to discharge sewage, 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 discharge flying distance becomes longer and longer. Therefore, along the direction from top to bottom, when the distance between the central axis of the rotary connection hole 13 and the transition area 111 gradually increases, the distance between the sewage discharge port 21 of the sewage discharge pipe 2 and the inner wall surface of the sewage discharge box 1 during the process of rotating to discharge sewage also gradually increases. This is favorable to reduce the probability that the sewage discharged from the sewage discharge pipe 2 is blown onto the inner wall surface of the sewage discharge box 1, and allows the sewage to contact the inner wall surface of the sewage discharge box 1 as little as possible, or to fall directly without contact, which is favorable to reduce the sewage remaining or caught on the inner wall surface of the sewage discharge box 1, which is favorable to improve the cleanliness and hygiene of the sewage discharge box 1, and is favorable to improve the user experience.

[0034] 14 , the waste discharge area 11 further includes an outlet area 112 located below the rotary connection hole 13. The outlet area 112 defines a waste outlet 14 of the waste discharge box 1, and the central axis of the waste outlet 14 deviates from the boundary surface 15.

[0035] In this proposal, the sewage outlet 14 of the sewage discharge box 1 is positioned at the bottom of the sewage discharge area 11, so that the central axis of the sewage outlet 14 is offset from the boundary surface 15. As a result, the sewage outlet 14 of the sewage discharge box 1 and the rotary connection hole 13 (corresponding to the sewage inlet of the sewage discharge box 1) are arranged in an offset eccentric layout in the horizontal width direction (left and right direction in the figure), that is, they are not located directly below the rotary connection hole 13, but are located below the side of the rotary connection hole 13.

[0036] Compared with directly locating the sewage outlet 14 directly below the central axis of the rotating connection hole 13, the offset eccentric layout design of the present invention is advantageous in reducing the distance between the sewage outlet 21 of the sewage discharge pipe 2 and the sewage outlet 14 of the sewage discharge box 1 (when located in the highest position as shown in Figure 7), and thus in reducing the rotation angle when the sewage discharge pipe 2 rotates from the initial position to the sewage discharge position, thereby achieving the purpose of fast sewage discharge.

[0037] In addition, compared with arranging the sewage outlet 14 directly below the central axis of the rotary connection hole 13 (as shown in FIG. 13 ), the present invention adopts an offset eccentric layout design, which can reduce the space occupied by the area of ​​the sewage discharge box 1 that is located directly below the central axis of the rotary connection hole 13, which is advantageous for further reducing the volume of the sewage discharge box 1 and further improving the flexibility and adaptability of the sewage discharge box 1.

[0038] In one exemplary embodiment, the vertical section perpendicular to the boundary surface 15 is referred to as the vertical central vertical plane, i.e., the cross section is obtained by cutting the waste discharge box 1 along the vertical direction perpendicular to the boundary surface 15. As shown in Fig. 14 and Fig. 15, the contour line of the transition area 111 in the vertical central vertical plane includes a first segment 1111, a second segment 1112, and a third segment 1113, which are connected sequentially from top to bottom. The area corresponding to the third segment 1113 is configured to directly face the waste discharge outlet 21 of the waste discharge pipe 2 when the waste discharge pipe 2 rotates to the waste discharge position, as shown in Fig. 9.

[0039] The third segment 1113 is an inclined straight line segment, as shown in FIG. 14, and is configured to extend downwardly at an angle in a direction approaching the non-waste discharge area 12.

[0040] When the waste discharge pipe 2 rotates to the waste discharge position, a large amount of waste in the waste discharge pipe 2 is discharged to the outside. At this time, as shown in Fig. 9, the waste discharge port 21 of the waste discharge pipe 2 faces the area corresponding to the third segment 1113 of the transition area 111, so a large amount of waste may contact the area and fall along the area. Compared with setting an arc segment (for example, the dashed arc segment showing a comparative example in Fig. 15), in this proposal, the third segment 1113 is set as an inclined straight segment, the length of the straight segment is shorter than the arc segment, the area corresponding to the third segment 1113 is reduced, which is convenient for the waste to quickly leave the area, and the area has a larger inclination angle, which is conducive to the efficient and rapid sliding of the waste, thereby achieving a more efficient waste discharge sliding effect.

[0041] In other words, the area corresponding to the third segment 1113 forms a waste discharge guide surface, as shown in FIG. 9, which can play the role of a highly efficient waste discharge guide.

[0042] In one exemplary embodiment, as shown in FIGS. 14 and 15, the first segment 1111 is configured in an arc shape, and the second segment 1112 extends vertically.

[0043] In this proposal, the first segment 1111 is set as an arc segment, and the second segment 1112 is set as a vertical straight line segment, so that the area corresponding to the first segment 1111 is an arc surface, and the area corresponding to the second segment 1112 is a vertical surface (i.e., a plane perpendicular to the horizontal surface, or called a vertical surface). Compared with designing the first segment 1111 and the second segment 1112 as one complete arc segment, this proposal can reduce the length of the second segment 1112, thereby reducing the area of ​​the area corresponding to the second segment 1112, which helps to improve the efficiency of waste discharge.

[0044] Furthermore, compared with the arc surface, the vertical surface is less likely to catch waste and the caught waste is more likely to slide off. Also, compared with the arc surface, the vertical surface can reduce the width of the waste discharge area 11 in the horizontal direction perpendicular to the boundary surface 15 (i.e., the width in the left-right direction in the figure), and occupy less external space, which is advantageous for further reducing the volume of the waste discharge box 1 and further improving the flexibility and adaptability of the waste discharge box 1.

[0045] 15, a comparative example is designed in which the second segment 1112 is an arch segment concentric with the first segment 1111, as shown in FIG. 15. As a result of calculation, the length of the second segment 1112 in the comparative example increases by about 6%.

[0046] 14, the contour line of the outlet area 112 in the vertical center plane in the longitudinal direction includes a fourth segment 1121 and a fifth segment 1122. The fourth segment 1121 is smoothly connected to the lower end of the third segment 1113, so that waste in the area corresponding to the third segment 1113 can smoothly slide into the waste outlet 14 and be discharged, which contributes to improving the efficiency of waste discharge. The fifth segment 1122 is disposed at a distance from the fourth segment 1121, and the waste outlet 14 is formed between the fifth segment 1122 and the fourth segment 1121.

[0047] In one exemplary embodiment, as shown in Figure 14, the fifth segment 1122 includes an outlet segment 1123 and a transition segment 1124. The outlet segment 1123 is disposed opposite to the fourth segment 1121, and forms a waste outlet 14 between the fourth segment 1121 and the outlet segment 1123. As shown in Figures 9 and 10, the inclined surface 22 of the waste discharge pipe 2 has a widened portion disposed along the direction of waste inclination discharge.

[0048] 10, the outlet segment 1123 is arranged so that when the waste discharge pipe 2 is rotated to the waste discharge position, the outlet segment 1123 and the contour line of the inclined surface 22 of the waste discharge pipe 2 in the longitudinal central vertical plane match each other, thereby forming a widened guide portion for guiding the discharge of waste in the outlet segment 1123. The inclined surface 22 of the waste discharge pipe 2 refers to the lower part of the inner wall of the waste discharge pipe 2 when the waste discharge pipe 2 is located at the waste discharge position, and the waste in the waste discharge pipe 2 is discharged downward along the side wall of that portion.

[0049] The lower end of the transition segment 1124 and the upper end of the outlet segment 1123 are smoothly connected, and the upper end of the transition segment 1124 and the contour line of the non-waste discharge area 12 in the longitudinal central vertical plane are smoothly connected.

[0050] In this case, when the sewage discharge pipe 2 is located at the sewage discharge position, the area corresponding to the outlet segment 1123 is located at the extension surface of the inclined surface 22 of the sewage discharge pipe 2, and the area conforms to the shape of the inclined surface 22 of the sewage discharge pipe 2. Thus, an enlarged guide portion is formed in the area corresponding to the outlet segment 1123, which can play a relatively good guiding role for the sewage, and is conducive to the sewage entering the sewage outlet 14 of the sewage discharge box 1 along this portion quickly, smoothly and efficiently.

[0051] On the other hand, the impact on waste discharge of the area corresponding to the transition segment 1124 is negligible, and therefore the position of the transition segment 1124 may be raised to a certain extent and then smoothly connected to the non-waste discharge area 12, thereby further reducing the volume of the waste discharge box 1.

[0052] In one example, the outlet segment 1123 is arc-shaped, which is advantageous for the waste to slide smoothly and smoothly along the area corresponding to the outlet segment 1123.

[0053] In one exemplary embodiment, as shown in FIG. 14, the contour line in the longitudinal central vertical plane of the non-waste discharge area 12 includes a sixth segment 121, a seventh segment 122, and an eighth segment 123, which are connected sequentially from top to bottom.

[0054] The sixth segment 121 is smoothly connected to the first segment 1111. The eighth segment 123 is smoothly connected to the contour line of the exit area 112 in the longitudinal center vertical plane.

[0055] 14, the sixth segment 121 is set to be an arc shape and coincides with the center of the first segment 1111. The seventh segment 122 extends along the vertical direction, as shown in FIG.

[0056] In this way, the sixth segment 121 and the first segment 1111 form a continuous arc, so that the shape of the portion forms a regular arc surface, which is easy to process and mold. On the other hand, if the seventh segment 122 is set as a vertical straight line segment, the length of the straight line segment is shorter than that of the sixth segment 121, and the distance between the straight line segment and the central axis of the rotation connection hole 13 is also shorter, which is advantageous in reducing the width of the non-waste discharge area 12 in the horizontal direction perpendicular to the boundary surface 15 (i.e., the width in the left-right direction in the figure), and in further reducing the volume of the waste discharge box 1.

[0057] As a comparative example, as shown by the dotted line in Figure 16, the waste discharge box 1 is designed to have a regular shape, and the contour line of the inner wall surface of the waste discharge box 1 in the vertical center plane in the longitudinal direction is a regular circle, and the contour line is a perfect circle formed by the extension of the first segment 1111 and the sixth segment 121.

[0058] As a result of calculations, it has been found that the embodiment of the present disclosure adopts an asymmetrical irregular shape design, which can reduce the inner wall area (the area of ​​the vertical central surface in the longitudinal direction) and the overall volume of the waste discharge box 1 by approximately 34%, i.e., the volume is reduced by more than 1 / 3, and the space occupied by the waste discharge box 1 in the toilet is greatly saved.

[0059] Therefore, in the waste discharge box 1 according to the embodiment of the present disclosure, the shape of the waste discharge box 1 is optimized, the volume of the waste discharge box 1 is effectively reduced, and the adaptability of the waste discharge system 100 is also greatly improved.

[0060] In one exemplary embodiment, as shown in FIG. 14, the top end of the seventh segment 122 is higher than the top end of the second segment 1112 and the bottom end of the seventh segment 122 is higher than the bottom end of the second segment 1112.

[0061] In this way, the position of the seventh segment 122 is relatively high and the distance between it and the boundary surface 15 is relatively small, which is advantageous for further reducing the volume of the sewage discharge box 1, and the position of the second segment 1112 is relatively low and the distance between it and the boundary surface 15 is relatively large, which is advantageous for avoiding interference between the sewage discharge area 11 and the sewage discharge pipe 2 or excessive contact with the sewage.

[0062] In one exemplary embodiment, as shown in FIG. 9, the space enclosed by the waste discharge area 11 is configured such that the maximum rotation angle α provided to the waste discharge pipe 2 is in the range of 100° to 120°.

[0063] In other words, due to the restriction of the shape of the waste discharge area 11, the waste discharge pipe 2 can only rotate 100° to 120° in the waste discharge box 1. If it continues to rotate, it will interfere with the waste discharge box 1.

[0064] Compared with the proposal in which the waste discharge pipe 2 rotates 180° (from vertically upward to vertically downward), in this proposal, the waste discharge pipe 2 only needs to rotate 100°~120°, which reduces the length of time for rotation and is advantageous for improving waste discharge efficiency. Also, in this proposal, the volume of the waste discharge box 1 is reduced, which is advantageous for improving the flexibility and adaptability of the waste discharge box 1.

[0065] 11, 12 and 14, an embodiment of the present disclosure further provides a waste discharge system 100, comprising a waste discharge box 1 according to any of the above embodiments, a waste discharge pipe 2, and a driving device 3. The waste discharge pipe 2 and the waste discharge box 1 are rotatably connected. The driving device 3 is connected to the waste discharge pipe 2 and configured to drive the waste discharge pipe 2 to rotate relative to the waste discharge box 1.

[0066] The waste discharge system 100 according to the embodiment of the present disclosure includes the waste discharge box 1 in any of the above embodiments, and therefore has all the beneficial effects of any of the above embodiments, which will not be described repeatedly here.

[0067] In one exemplary embodiment, as shown in FIG. 11, the waste discharge box 1 includes a box body 17 and a box cover 16. As shown in FIG. 3, a rotary connection hole 13 is provided in the box body 17. The box cover 16 and the box body 17 are cover-connected. As shown in FIG. 23, a seal ring 18 is provided between the box cover 16 and the box body 17, and a seal 19 is provided between the waste discharge pipe 2 and the waste discharge box 1. A connection hole 161 is provided in the box cover 16, and a connection part 23 is provided in the waste discharge pipe 2. The driving device 3 is connected to the connection part 23 through the connection hole 161 and configured to drive the waste discharge pipe 2 to rotate. The driving device 3 may be a motor.

[0068] The waste discharge principle of the waste discharge system 100 is as follows (as shown in Figs. 7 to 9).

[0069] When rotating to discharge waste, waste in the bowl 202 of the toilet body 200 enters the waste discharge pipe 2, and the waste discharge pipe 2 is driven by the drive unit 3 to rotate 100° to 120° to the right from the initial position (i.e., the position where the waste discharge outlet 21 faces straight up, as shown in Figure 7) to reach the waste discharge position (as shown in Figure 9), and the waste is discharged from the waste discharge outlet 21 through the waste outlet 14 of the waste discharge box 1.

[0070] After the waste discharge operation is completed, the waste discharged by the waste discharge pipe 2 flows through the waste outlet 14 of the waste discharge box 1 into the shifter 204, and is then guided to an external waste discharge passage, and a seal ring 18 is provided between the shifter 204 and the waste discharge box 1. Meanwhile, the waste discharge pipe 2 is returned to its initial position by the drive device 3 (as shown in FIG. 7), and is used again the next time the waste discharge function is performed.

[0071] In one exemplary embodiment, as shown in Figures 18 and 23, the waste discharge system 100 further includes a cleaning device 4. The cleaning device 4 is connected to the waste discharge box 1 and configured to spray cleaning liquid into the inside of the waste discharge box 1, so as to play a role in cleaning the waste discharge box 1, which is conducive to discharging the waste remaining or stuck in the waste discharge box 1, thereby improving the cleaning degree of the waste discharge box 1 and maintaining a good waste discharge effect.

[0072] In one exemplary embodiment, as shown in Fig. 23, the cleaning device 4 includes a liquid supply pipe 41 and a spray component 42. The liquid supply pipe 41 and the waste discharge box 1 are in communication with each other. The spray component 42 is connected to the liquid supply pipe 41 and configured to spray cleaning liquid into the waste discharge box 1.

[0073] In this case, the liquid supply pipe 41 is connected to an external cleaning source (e.g., an external water source) to introduce cleaning liquid into the waste discharge box 1, and the cleaning liquid can be sprayed into the waste discharge box 1 by the spray part 42, which serves to clean the waste discharge box 1 and is advantageous in discharging waste remaining or stuck in the waste discharge box 1, thereby improving the cleaning degree of the waste discharge box 1 and maintaining a good waste discharge effect.

[0074] As shown in Figs. 1 to 9 and 17 to 22, an embodiment of the present disclosure further provides a toilet, which includes a toilet body 200 and the waste discharge system 100 in the above embodiment.

[0075] As shown in Figures 17 to 20, a toilet body 200 is provided with a bowl 202, and the bowl 202 is provided with a waste discharge outlet 2006. The waste discharge pipe 2 of the waste discharge system 100 and the waste discharge outlet 2006 are in communication with each other, and the central axis of the waste discharge outlet 2006 and the rotation axis of the waste discharge pipe 2 are collinear.

[0076] The toilet according to the embodiment of the present disclosure includes the waste discharge system 100 in the above embodiment, and therefore has all the beneficial effects mentioned above, which will not be repeated here.

[0077] In one exemplary embodiment, as shown in Figures 17 and 18, the toilet body 200 is provided with a flush port 2002 that communicates with the bowl 202. The flush port 2002 may take the form of a pipe fitting that is attached to a corresponding position on the toilet body 200 and connected to a first outlet of the diversion valve 206 via a pipe.

[0078] As shown in Figures 17, 18, 19 and 20, the toilet further includes a diversion valve 206. The diversion 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 to the water inlet. The water inlet is configured to be connected to a water source. The first water outlet is configured to be connected to the flushing inlet 2002 to supply water to the bowl 202. The second water outlet is configured to be connected to the flushing device 4 of the waste discharge system 100 to supply water to the flushing device 4.

[0079] When it is necessary to flush the toilet and discharge waste, the water inlet and the first water outlet are connected, and water passes through the diverter valve 206 into the toilet flush port 2002, then into the toilet bowl 202, and enters the waste discharge pipe 2 together with the waste in the bowl 202. As the waste discharge pipe 2 rotates downward, the water is discharged from the waste discharge pipe 2, passes through the waste outlet 14 of the waste discharge box 1 together with the waste, enters the shifter 204, and finally enters the external waste discharge passage.

[0080] After the sewage is discharged by flushing, the diversion valve 206 can switch to another waterway to connect the water inlet and the second water outlet, and the water enters the cleaning device 4 through the diversion valve 206, and is sprayed by the cleaning device 4 into the inside of the sewage discharge box 1 to clean the inside of the sewage discharge box 1, thereby improving the cleanliness of the sewage discharge box 1, and allowing the sewage discharge system 100 to maintain a relatively good sewage discharge effect.

[0081] In addition, before flushing the toilet and discharging waste, the water inlet and the first water outlet can be connected, and water can pass through the diverter valve 206 into the toilet flush port 2002, and then into the toilet bowl 202 to wet the inner wall surface of the bowl 202, which is advantageous for the waste to slide off in a timely manner during the subsequent flush waste discharging process, and reduce the waste remaining or stuck on the inner wall surface of the bowl 202.

[0082] Before the sewage discharge pipe 2 rotates to discharge the sewage, the water inlet and the second water outlet may be connected, so that water enters the cleaning device 4 through the water diversion valve 206 and is sprayed into the inside of the sewage discharge box 1 by the cleaning device 4 to wet the inner wall surface of the sewage discharge box 1, which is advantageous for the sewage to slide off in a timely manner in the subsequent water-washed sewage discharge process and reduce the sewage remaining or stuck on the inner wall surface of the sewage discharge box 1.

[0083] In this way, water can be supplied for different functions of the toilet by controlling the selective communication of the internal water passage of the water distribution valve 206. Compared with a proposal in which multiple water valves are installed and each is connected to the flush port 2002 and the flushing device 4, this proposal is advantageous in reducing the number of components and the length of the pipes in the toilet, thus simplifying the structure of the toilet and reducing the production cost.

[0084] In one exemplary embodiment, the toilet body 200 is provided with a plurality of water outlets, the plurality of water outlets being provided at the top of the bowl 202. The flush port 2002 communicates with the bowl 202 via the plurality of water outlets.

[0085] In other words, a water supply passage is provided at the top of the toilet body 200, and water enters the water supply passage through the flush port 2002, flows out of the water supply passage through multiple water distribution ports, and enters the bowl 202, thereby cleaning and wetting the inner wall surface of the bowl 202 and increasing the water level in the toilet puddle, thereby increasing the gravitational potential of the waste and liquid in the waste discharge pipe 2.

[0086] The toilet of the embodiment of the present disclosure mainly uses the driving device 3 to drive the waste discharge pipe 2 in a downward rotating motion to discharge the waste, and the principle is that the waste is mainly fallen and discharged by the gravitational potential and falling inertia of the waste and liquid in the pipe; therefore, the water provided from the water outlet at the top of the bowl 202 helps to improve the waste discharge effect, and there is no need to provide a jet nozzle at the bottom of the bowl 202 and use the large water flow from the jet nozzle to flush the waste into the waste discharge pipe 2.

[0087] Therefore, the toilet according to the embodiment of the present disclosure can eliminate the jet nozzle at the bottom of the bowl 202 and only leave the water outlet at the top of the bowl 202, which can reduce noise while ensuring the waste discharge effect, and is favorable for improving the user experience.

[0088] The water coming out of the water outlet at the top of bowl 202 flows downward along the inner wall surface of bowl 202, so the strength of the water flow is relatively small and the noise is also relatively small; in contrast, the water flow from the outlet at the bottom of bowl 202 is strong and the noise is also relatively large.

[0089] Incidentally, current toilets, whether tankless or tank-equipped, basically clean the inner wall surface of bowl 202 with water coming out of a water outlet at the top of bowl 202, expel waste with water jetted from a nozzle at the bottom of bowl 202, and use the S-bend pipe of the ceramic body itself to create a siphon function and realize the waste discharge function. The waste discharge is mainly achieved by using a large water jet from the nozzle to send the waste into the S-bend pipe, which creates a lot of noise when in use.

[0090] In contrast, in the toilet according to the embodiment of the present disclosure, the toilet body 200 only has a water outlet (also called a flushing water outlet on the rim) at the top of the bowl 202, and does not have a jet port at the bottom of the bowl 202, which can effectively reduce noise during the toilet flush waste discharge process and improve the user experience. And the driving device 3 controls the rotation of the waste discharge pipe 2 to directly discharge waste, eliminating the S-bend pipe of the current siphon toilet, which can shorten the waste discharge path, realize a rapid waste discharge function, and have a good waste discharge effect.

[0091] 17 and 18, the toilet further includes a water tank 210 and a pump 208. An input end of the pump 208 is connected to the water tank 210, an output end of the pump 208 is connected to a water inlet, and the pump 208 is configured to pump water in the water tank 210 to the diversion valve 206.

[0092] In this way, by controlling the starting and stopping of pump 208, the opening and closing of the waterway within the toilet can be controlled, and by controlling diversion valve 206, the switching of the waterway within diversion valve 206 can be controlled, which is advantageous for realizing automated control.

[0093] In one exemplary embodiment, the toilet body 200 is provided with a mounting cavity 2004, which is located behind the bowl 202, as shown in Figures 17 and 18. The waste discharge system 100, at least a portion of the diversion valve 206, at least a portion of the water storage tank 210, and the pump 208 are located within the mounting cavity 2004.

[0094] As a result, compared with the proposal in which the water tank 210 is provided above the toilet body 200, the toilet of the embodiment of the present disclosure has a relatively compact overall structure and a relatively small volume, which is easy to store and transport. In addition, the installation space required for the toilet can be reduced, which is advantageous in reducing the space occupied by the toilet room.

Those skilled in the art can make modifications and changes in the form and details of implementation without departing from the spirit and scope disclosed in the present disclosure, but the patent protection scope of the present disclosure is subject to the scope described in the claims.
