Description

Technology Field

[0001] The present application relates to kitchen and bathroom technology, but is not limited thereto, and in particular relates to waste discharge pipes, waste discharge systems, waste discharge control methods, waste discharge control devices, and toilets. Background Technology

[0002] Currently, the waste discharge method of the waste discharge pipe applied to the waste discharge system installed on the back of the toilet usually adopts a method of discharging only the amount of water stored in the initial state. Therefore, the amount of water stored in the initial state of the toilet has a significant impact on the waste discharge cleaning effect. To improve the waste discharge cleaning effect, the amount of water stored in the initial state must be increased, and the waste discharge pipe must be made relatively high so that the toilet's water seal is relatively high. However, while this increases the amount of water stored, the relatively high water seal surface makes it easy for water to splash when using the toilet, affecting the user experience.

[0015] As illustrated in FIGS. 1 to 4, an embodiment of the present disclosure provides a waste discharge pipe (1) comprising a pipe body (11). The pipe body (11) is provided with a waste inlet (113), a waste discharge port (114), and an overflow port (115). The waste discharge port (114) is oriented differently from the direction of the waste inlet (113). The waste inlet (113) is installed to communicate with the waste discharge outlet (411) of the toilet body (4). The pipe body (11) is installed to rotate between an initial position and a waste discharge position, surrounding the central axis of the waste inlet (113) relative to the toilet body (4).

[0016] Here, as illustrated in FIGS. 2 and 3, the pipe body (11) is in its initial position with the opening of the waste discharge port (114) facing upward, the overflow port (115) located below the waste discharge port (114), and also located above the waste inlet port (113).

[0017] The waste discharge pipe (1) provided in the embodiment of the present disclosure includes a pipe body (11) having a waste inlet (113), a waste outlet (114), and an overflow port (115). Since the waste inlet (113) of the pipe body (11) can be connected to the waste discharge outlet (411) of the toilet body (4), waste inside the toilet body (4) can enter the waste discharge pipe (1) through the waste inlet (113). Since the waste discharge outlet (411) of the toilet body (4) is usually installed at the rear, the waste inlet (113) of the pipe body (11) is correspondingly installed at the front after the toilet assembly is completed, and may be installed facing directly forward or at an appropriate angle. Since the pipe body (11) can rotate between the initial position and the waste discharge position while surrounding the central axis of the waste inlet (113) in relation to the toilet body (4), the waste can be discharged from the waste discharge port (114) by the action of gravitational energy and falling inertia, thereby implementing a flipping waste discharge function.

[0018] Here, as illustrated in FIGS. 9 and 10, the opening of the waste outlet (114) is positioned upward when the pipe body (11) is in its initial position, and the overflow port (115) is positioned above the waste inlet (113) to ensure that a water seal can be formed inside the toilet. At this time, since the overflow port (115) is positioned below the waste outlet (114), liquid located above the overflow port (115) in the waste discharge pipe (1) flows out through the overflow port (115) until the water seal surface is aligned with the lowest point of the overflow port (115). Thus, the overflow port (115) can serve to lower the height of the water seal surface position, which is advantageous for improving the user's experience by preventing water from splashing when the user uses the toilet.

[0019] When waste discharge is required, water begins to enter the interior of the toilet body (4), and since the amount of water inflow is much greater than the overflow flow rate of the overflow port (115), the water sealing surface inside the toilet quickly rises to the position where the waste discharge port (114) is located, as shown in FIGS. 11 and 12, increasing the volume of the flushing water and the gravitational energy of the flushing water, and then when the waste discharge pipe (1) rotates downward to the waste discharge position (as shown in FIGS. 13 and 14), a relatively good waste cleaning effect can be achieved by utilizing the relatively large volume of water and gravitational energy.

[0020] Accordingly, the present method can control the height of the toilet water seal surface through the overflow port (115) by adding an overflow port (115) to the waste discharge pipe (1), and the toilet water seal surface is positioned at a relatively low position in a non-waste discharge state (as shown in FIGS. 9 and 10), and furthermore, it can avoid the toilet water seal surface being too high so that water splashes easily when the user uses the toilet; additionally, by making the overflow flow rate of the overflow port (115) much smaller than the water inflow amount of the toilet body (4), the toilet water seal surface can be raised to a relatively high position when waste is discharged (as shown in FIGS. 11 and 12), thereby increasing the gravitational energy of the flush water and enhancing the waste discharge cleaning effect of the toilet.

[0021] In addition, compared to a method of changing the height of the water seal by controlling the position change of the waste discharge pipe (1) (i.e., in the standby state, the waste discharge pipe (1) is positioned at an inclined position to lower the water seal surface, and when waste discharge is required, the waste discharge pipe (1) is first controlled to rotate to an upright position to raise the water seal surface, and then the waste discharge pipe (1) is controlled to rotate downward to discharge waste), the present method can achieve the effect of changing the water seal height by simply improving the structure of the waste discharge pipe (1), and the position of the waste discharge pipe (1) can be changed between the initial position and the waste discharge position, and since the transition to the inclined position in the standby state is eliminated, the electrical control procedure of the waste discharge pipe (1) can be simplified and the electrical control failure rate can be reduced.

[0022] In one exemplary embodiment, as illustrated in FIGS. 1 to 4, the waste discharge pipe (1) also includes a rotary connection (12) connected to the pipe body (11) and installed to connect a drive device (3) that drives the pipe body (11) to rotate around the central axis of the waste inlet (113).

[0023] In this way, after assembly is completed, the drive device (3) rotates the rotating connection part (12) so that the waste discharge pipe (1) is driven to rotate around the central axis of the waste inlet (113) in relation to the toilet body (4).

[0024] Here, the drive device (3) can be a structure such as an electric motor or a gearbox. The shape of the rotary connection part (12) is not limited and, for example, it may be a non-circular ring-shaped convex part for connecting to an electric motor shaft, or a gear-shaped protrusion may be installed inside to make it easier to connect to a gear shaft.

[0025] In one exemplary embodiment, as illustrated in FIGS. 1 to 4, the waste discharge pipe (1) also includes a connecting convex member (13) located outside the waste inlet (113) and connected to the outer wall of the pipe body (11), and the inner diameter of the connecting convex member (13) is larger than the diameter of the waste inlet (113).

[0026] The installation of the connecting convex member (13) makes it convenient for the waste discharge pipe (1) to implement a rotational connection with the waste discharge box (2) or other structures, and also makes it convenient for the mounting of sealing parts, and prevents leakage of waste by implementing a sealing combination between the waste discharge pipe (1), the waste discharge box (2), and the toilet bowl part (41).

[0027] In one exemplary embodiment, as shown in FIG. 3, one end of the pipe body (11) forms a waste discharge port (114), the other end of the pipe body (11) is installed as a closed port, and a waste inlet port (113) is installed on the side wall of the pipe body (11).

[0028] Compared to a standard L-shaped elbow pipe, this method is advantageous for reducing the horizontal length of the waste discharge pipe (1), which shortens the flow path of the waste and further improves the waste discharge performance of the toilet. On the other hand, this also reduces the requirement for mounting space for the waste discharge pipe (1) and further reduces the volume of the toilet.

[0029] In one exemplary embodiment, the pipe body (11) includes a tubular portion (111) and a back cover portion (112), as shown in FIG. 3.

[0030] Here, a waste discharge port (114) is formed at one end of the tubular section (111). A waste inlet port (113) is installed on the side wall of the tubular section (111) and extends to the other end of the tubular section (111). A back cover portion (112) is connected to the other end of the tubular section (111) and covers the other end of the tubular section (111).

[0031] In the present invention, the pipe body (11) includes a tubular section (111) and a back cover section (112). One end of the tubular section (111) forms a waste discharge port (114), and the other end is covered by the back cover section (112). Since the waste discharge port (114) is installed on the side wall of the tubular section (111) and extends to the end of the tubular section (111) that is close to the back cover section (112), the waste entering the pipe body (11) from the waste discharge port (114) during waste discharge can basically only flow in the direction where the waste discharge port (114) is located. This is advantageous for realizing the flow of waste in a designated direction within the waste discharge pipe (1), and is advantageous for avoiding the accumulation of waste on the bottom of the pipe body (11) and improving the waste discharge performance of the toilet.

[0032] In one exemplary embodiment, as shown in FIG. 3, the back cover portion (112) is concave in a direction away from the waste discharge port (114), so that the maximum distance between the back cover portion (112) and the waste discharge port (114) is greater than the maximum distance between the waste inlet port (113) and the waste discharge port (114).

[0033] By doing this, the lowest point of the pipe body (11) in the initial position can be lowered further, which is advantageous for increasing the amount of water stored in the toilet in the initial position, and thus is advantageous for further improving the waste discharge cleaning performance of the toilet.

[0034] In one exemplary embodiment, the tubular portion (111) includes a first plate portion (1111), a second plate portion (1112), a third plate portion (1113), and a fourth plate portion (1114) connected sequentially at the head and end along the circumferential direction, as illustrated in FIGS. 1, 2 and 4.

[0035] Here, the first plate section (1111) is a first flat woven plate, and the dirt inlet (113) is installed on the first plate section (1111).

[0036] This makes it convenient for processing and molding the waste inlet (113), convenient for processing other structures in the waste inlet (113), and is used to implement a rotatable connection between the waste discharge pipe (1) and the waste discharge box (2), and furthermore is advantageous for lowering the difficulty of mounting the waste discharge pipe (1).

[0037] The aforementioned rotating connecting part (12) is installed on the third plate part (1113), and the connecting convex part (13) is installed on the first plate part (1111).

[0038] In one exemplary embodiment, the waste discharge pipe (1) rotates to one side where the fourth plate section (1114) is located during the process of rotating from the initial position to the waste discharge position. The second plate section (1112) is a second plain woven plate. The third plate section (1113) is an arc-shaped plate, and the arc-shaped plate is bent in a direction away from the first plate section (1111), as illustrated in FIGS. 1, 2, and 4.

[0039] As illustrated in FIGS. 1 and 4, the fourth plate section (1114) includes a third flat plate connected to the third plate section (1113) and a curved plate (1115) connected to the first plate section (1111); along the direction near the waste discharge port (114), the curved plate (1115) is bent inward in a concave manner along the direction near the second plate section (1112) and the third plate section (1113).

[0040] In a general design, the cylindrical section (111) is designed as a circular pipe structure, and the radius of the circular pipe is equal to the radius of the third plate section (1113). In this method, the cylindrical section (111) is installed as an irregular irregular structure, which is equivalent to extending half of the cylinder close to the toilet body (4) of a conventional circular pipe structure outward to form a structure close to a prismatic shape (including three flat woven plates). By doing so, the flow area of ​​the cylindrical section (111) is increased, which is advantageous for improving the waste discharge performance of the waste discharge pipe (1). The curved plate (1115) of the fourth plate section (1114) is positioned inward so that waste can easily collect and be discharged, and so that waste does not accumulate and remain at the corner positions of the first plate section (1111) and the fourth plate section (1114), which is advantageous for improving the waste discharge performance of the waste discharge pipe (1).

[0041] In one exemplary embodiment, an overflow port (115) is installed in the second plate portion (1112) as shown in FIGS. 1 and 2.

[0042] By doing this, as the waste discharge pipe (1) rotates from the initial position to the waste discharge position, the waste flows away from the overflow port (115), and the waste can be avoided from accumulating in the overflow port (115) during the waste discharge process.

[0043] Additionally, since the first plate (1111) is rotatably connected to the waste discharge box (2), the third plate (1113) must be connected to the drive device (3). If the overflow port (115) is installed on the second plate (1112), it is advantageous for the overflowing water to fall smoothly, not to be blocked by the connection structure, and to prevent the drive device (3) from coming into contact with water. It is also advantageous for preventing the overflow port (115) from being blocked by waste during the waste discharge process.

[0044] In one exemplary embodiment, along the direction from the first plate portion (1111) to the third plate portion (1113), the second plain weave plate and the third plain weave plate extend at an angle toward each other, as shown in FIGS. 1 and 4.

[0045] Compared to the method in which the second flat woven plate and the third flat woven plate are parallel to each other, this method is advantageous for further increasing the flow area of ​​the tubular part (111) and further increasing the waste discharge performance of the waste discharge pipe (1).

[0046] In addition, this installation is advantageous for increasing the width of the first flat woven plate, further increasing the area of ​​the waste inlet (113), and further increasing the waste discharge performance of the waste discharge pipe (1).

[0047] In one exemplary embodiment, the first plate (1111), the second plate (1112), the third plate (1113), and the fourth plate (1114) are smoothly connected, as shown in FIGS. 1 and FIGS. 4. This prevents the accumulation of dirt and debris from having corners within the dirt discharge pipe (1).

[0048] In one exemplary embodiment, the diameter of the waste inlet (113) is greater than half the length of the tubular portion (111), as shown in FIG. 10. This makes the area of ​​the waste inlet (113) relatively large, which is advantageous for further improving waste discharge performance.

[0049] In one exemplary embodiment, as shown in FIG. 3, when the waste discharge pipe (1) is in its initial position, the width (L1) of the overflow port (115) is in the range of 5 mm to 30 mm, and the height (L2) of the overflow port (115) is in the range of 2 mm to 10 mm.

[0050] The height and width of the overflow port (115) affect the overflow speed of the overflow port (115), the rising speed of the water seal surface, and the strength of the waste discharge pipe (1). If the height and width of the overflow port (115) are too large, the speed of the overflow water becomes too fast, and the amount of water required to rise the toilet water seal to the waste discharge port (114) increases. Additionally, the rising speed of the water seal surface becomes small, and it may also affect the strength of the waste discharge pipe (1).

[0051] According to the research results, the height of the overflow port (115) is limited to a range of 2 mm to 10 mm, for example, 2 mm, 4 mm, 6 mm, 8 mm, 10 mm, etc., and the width of the overflow port (115) is limited to a range of 5 mm to 30 mm, for example, 5 mm, 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, etc., and this can be taken into account the overflow speed of the overflow port (115), the rising speed of the water sealing surface, and the strength of the waste discharge pipe (1).

[0052] Of course, the height of the overflow port (115) is not limited to the range described above, and the width of the overflow port (115) is also not limited to the range described above and can be adjusted as needed.

[0053] In one exemplary embodiment, as shown in FIG. 3, the minimum distance (L3) between the center axis of the overflow port (115) and the dirt inlet (113) is within the range of 70 mm to 116 mm.

[0054] When the waste discharge pipe (1) is in its initial position, the position of the lowest point of the overflow port (115) determines the upper limit of the watertight surface inside the toilet. The position of the lowest point of the top wall of the outlet of the toilet bowl (41) determines the lower limit of the watertightness inside the toilet. As shown in FIG. 9, if the distance between the lowest point of the top wall of the outlet of the toilet bowl (41) and the center axis of the waste inlet (113) of the waste discharge pipe (1) is recorded as H2, the height (H0) of the watertightness inside the toilet at the initial position is equal to L3-H2. Therefore, H0 is positively related to L3, but if H0 is too large, water splashing is likely to occur when using the toilet, and if H0 is too small, the watertightness effect is poor and odors are likely to develop. On the other hand, increasing the radius (R) of the waste inlet (113) so that R becomes larger than H2 is advantageous for increasing the area of ​​the waste inlet (113) and further for improving waste discharge performance, but since the radius (R) of the waste inlet (113) must be smaller than L3, L3 also affects R.

[0055] According to the study, if the minimum distance (L3) between the center axis of the overflow port (115) and the waste inlet (113) is limited to a range of 70 mm to 116 mm, for example, 70 mm, 80 mm, 90 mm, 100 mm, 110 mm, 116 mm, etc., this allows the area of ​​the waste inlet (113) and the height (H0) of the toilet water seal to satisfy the requirements.

[0056] Of course, the minimum distance between the center axis of the overflow port (115) and the waste inlet (113) is not limited to the range described above and can be adjusted as needed.

[0057] In one exemplary embodiment, the central axis of the waste inlet (113) intersects perpendicularly with the central axis of the waste outlet (114), as shown in FIGS. 9, FIGS. 11 and FIGS. 13.

[0058] In this way, the pipe body (11) of the waste discharge pipe (1) can be in an upright position at the initial position and the waste inlet (113) can be directed straight forward, as shown in FIGS. 9, 11 and 13, and the waste discharge pipe (1) can rotate around a horizontal axis of rotation. Compared to the waste discharge pipe (1) rotating around an inclined axis of rotation, this method is advantageous for reducing the width of the rotational direction in which waste flows from the waste inlet (113) to the waste discharge outlet (114), and thus is advantageous for improving the waste discharge performance of the waste discharge pipe (1).

[0059] In addition, by installing it in this way, the waste discharge box (2) can also be in an upright position, which is advantageous for lowering the difficulty of mounting the waste discharge box (2) and increasing the stability and reliability of the waste discharge box (2).

[0060] As illustrated in FIG. 5, an embodiment of the present disclosure also provides a waste discharge system, comprising a waste discharge box (2), a waste discharge pipe (1) of any one of the embodiments described above, and a drive device (3).

[0061] Here, the waste discharge pipe (1) is located at least partially within the waste discharge box (2) and is rotatably connected to the waste discharge box (2).

[0062] The drive device (3) is connected to the waste discharge pipe (1) and drives the waste discharge pipe (1) to rotate relative to the waste discharge box (2).

[0063] The waste discharge system provided in the embodiment of this disclosure includes a waste discharge pipe (1) of any one of the embodiments described above, and thus possesses all the beneficial effects of any one of the embodiments described above, so it is not described further here.

[0064] Here, the waste discharge pipe (1) can be fully positioned in the waste discharge box (2).

[0065] Alternatively, the waste discharge pipe (1) may also be located only partially within the waste discharge box (2). The inlet pipe segment of the waste discharge pipe (1) may extend out of the waste discharge box (2) and be rotatably connected to the toilet body (4), and may also be connected to the waste discharge outlet (411) of the toilet bowl portion (41).

[0066] In one exemplary embodiment, the waste discharge box (2) includes a box body (21) and a box lid (22), as shown in FIG. 5. A waste inlet (211) is installed at the front of the box body (21), as shown in FIG. 13. The waste inlet (211) is connected to the waste discharge outlet (411) of the bowl portion (41) of the toilet body (4). A waste discharge pipe (1) is located within the waste discharge box (2), and the waste inlet (113) of the waste discharge pipe (1) is connected to the waste inlet (211) of the waste discharge box (2). A waste outlet (24) is installed at the bottom of the box body (21), as shown in FIG. 5. The box lid (22) is connected to the box body (21) by covering it. A sealing ring (25) is installed between the box lid (22) and the box body (21), as shown in FIG. 5, and a first sealing part (26) is installed between the waste discharge pipe (1) and the waste discharge box (2). A connecting hole (221) is installed in the box lid (22), as shown in FIG. 5, and a rotary connecting part (12) is installed in the waste discharge pipe (1). A drive device (3) is connected to the rotary connecting part (12) through the connecting hole (221) and drives the waste discharge pipe (1) to rotate. The drive device (3) may be a gearbox.

[0067] The waste discharge principle of this waste discharge system is as follows (as illustrated in FIGS. 9 to 14).

[0068] In the standby state, the waste discharge pipe (1) is in its initial position, as shown in FIGS. 9 and 10. The brush ring flush device (42) causes water to flow out and raise the height of the toilet water seal surface to align with the waste discharge port (114), as shown in FIGS. 11 and 12.

[0069] When rotating waste discharge, waste inside the bowl portion (41) of the toilet body (4) enters the waste discharge pipe (1), and the waste discharge pipe (1) rotates 100° to 135° to the right from the initial position (i.e., the position where the waste discharge port (114) is facing upward, as shown in FIGS. 11 and 12) under the drive of the drive device (3) to reach the waste discharge position (as shown in FIGS. 13 and 14), and the waste is discharged from the waste discharge port (114) and discharged through the waste outlet (24) of the waste discharge box (2).

[0070] After the waste discharge operation is completed, the waste discharged through the waste discharge pipe (1) flows into the shifter (5) through the waste outlet (24) of the waste discharge box (2) and is introduced into the external waste discharge passage, and a sealing ring is installed between the shifter (5) and the waste discharge box (2). The waste discharge pipe (1) is reset to an initial position (as shown in FIGS. 9 and 10) under the drive of the drive device (3), and is reapplied while waiting for the next waste discharge function.

[0071] As illustrated in FIGS. 6, 7 and 8, an embodiment of the present disclosure also provides a toilet, comprising a toilet body (4) and a waste discharge system of the above-described embodiment.

[0072] Here, a bowl portion (41) is installed in the toilet body (4), and a waste discharge outlet (411) is installed in the bowl portion (41). A waste discharge system is installed in the toilet body (4), and the waste inlet (113) of the waste discharge system is connected to the waste discharge outlet (411).

[0073] The toilet provided in the embodiment of this disclosure includes the waste discharge system of the above-described embodiment and thus possesses all the beneficial effects described above, so it is not described further here.

[0074] Here, the waste discharge box (2) is fixedly connected to the toilet body (4), and a second sealing part (27) is installed between the waste discharge box (2) and the toilet body (4).

[0075] In one exemplary embodiment, the waste discharge box (2) is arranged in a vertical direction, as shown in FIGS. 9, FIGS. 11 and FIGS. 13.

[0076] Compared to the method of arranging the waste discharge box (2) at an angle, the present method is advantageous for lowering the difficulty of installing the waste discharge box (2) and for reducing the volume of the toilet.

[0077] In one exemplary embodiment, a brush ring flush device (42) is installed in the toilet body (4) as shown in FIG. 7, and the toilet also includes a flow rate detection device (43) installed to detect the flow rate of water of the brush ring flush device (42).

[0078] By doing this, the amount of water discharged from the brush ring flush device (42) can be measured using the flow rate detection device (43), which is advantageous for controlling the amount of water discharged according to demand and furthermore, is advantageous for saving water resources.

[0079] The toilet provided in the embodiment of this disclosure includes the waste discharge system of the above-described embodiment and thus possesses all the beneficial effects described above, so it is not described further here.

[0080] An embodiment of the present disclosure also provides a method for controlling waste discharge and is applied to the toilet described above.

[0081] The toilet includes a toilet body (4), a brush ring flush device (42), and a waste discharge pipe (1). The waste discharge pipe (1) is equipped with a waste inlet (113), a waste outlet (114), and an overflow port (115). The waste inlet (113) is in communication with the waste discharge outlet (411) of the toilet body (4). The waste discharge pipe (1) is installed to rotate between an initial position and a waste discharge position relative to the toilet body (4). When the waste discharge pipe (1) is in the initial position, the overflow port (115) is located below the waste outlet (114) and above the waste inlet (113), and the watertight surface of the toilet is aligned with the lowest point of the overflow port (115), as illustrated in FIGS. 9 and 10.

[0082] The waste discharge box (2), waste discharge pipe (1), and drive device (3) constitute a waste discharge system installed on the back of the toilet. The waste discharge box (2) is fixedly connected to the waste discharge outlet (411) of the toilet body (4), and the waste discharge pipe (1) is located inside the waste discharge box (2). The drive device (3) is connected to the waste discharge pipe (1) and drives the waste discharge pipe (1) to rotate.

[0083] This rear-mounted waste discharge system replaces the traditional siphon pipe waste discharge / cleaning method, adopts a drop discharge structure, and discharges waste inside the toilet from the toilet bowl (41) and the toilet pipe using a natural gravity drop method. During the waste discharge process, the waste discharge pipe (1) rotates around a rotation axis to pour out waste, and under the action of gravity and discharge drop inertia, the waste inside the toilet bowl (41) is efficiently and quickly discharged through the waste discharge pipe (1).

[0084] Here, the waste discharge pipe (1) is installed to rotate between an initial position and a waste discharge position. When the waste discharge pipe (1) is in the initial position, it is as shown in FIGS. 9 and FIGS. 10, and since the overflow port (115) is located above the waste inlet (113) and also below the waste outlet (114), it ensures that a water seal can be formed inside the toilet. At this time, since the overflow port (115) is located below the waste outlet (114), the liquid located above the overflow port (115) inside the waste discharge pipe (1) flows out through the overflow port (115) until the water seal surface is aligned with the lowest point of the overflow port (115), and the water seal height at this time is H0, as shown in FIG. 9. Therefore, the overflow port (115) can serve to lower the height of the water sealing surface, which is advantageous for improving the user's experience by preventing water from splashing when the user uses the toilet.

[0085] When waste discharge is required, the brush ring flush device (42) sends water into the interior of the toilet body (4), and since the amount of water inflow is much greater than the overflow flow rate of the overflow port (115), the water sealing surface inside the toilet quickly rises to the position where the waste discharge port (114) is located, as shown in FIGS. 11 and 12, and as the water sealing height increases Hs to reach H1, the volume of the cleaning water and the gravitational energy of the cleaning water are increased, and the waste discharge pipe (1) is controlled to rotate downward to the waste discharge position, as shown in FIGS. 13 and 14, that is, a relatively good waste discharge cleaning effect can be achieved by utilizing a relatively large water flow rate and gravitational energy.

[0086] Therefore, by adjusting the difference between the height of the initial water seal surface and the height of the water seal surface at the time of discharge drop during the waste discharge process, the waste discharge efficiency can be increased and the waste discharge effect can be enhanced.

[0087] As illustrated in FIG. 15, the waste discharge control method includes the following steps.

[0088] Step S102: Based on the fact that the waste discharge pipe is in its initial position, the brush ring flush device is controlled to flush water to the bowl surface of the toilet body, thereby increasing the water seal height of the toilet.

[0089] Step S104: Control the waste discharge pipe to rotate downward from the initial position to the waste discharge position to discharge the waste.

[0090] The waste discharge control method provided in the embodiment of this disclosure is to control the rotation of the waste discharge pipe (1) between the initial position and the waste discharge position. Compared to a method of changing the water seal height by controlling the position change of the waste discharge pipe (1) (i.e., in the standby state, the waste discharge pipe (1) is placed in an inclined position to lower the surface of the water seal, and when waste discharge is required, the waste discharge pipe (1) is first controlled to rotate to an upright position to raise the water seal height, and then the waste discharge pipe (1) is controlled to rotate downward), this method can implement the change in water seal height through the overflow port (115), and since the position of the waste discharge pipe (1) only needs to be changed between the initial position and the waste discharge position, the transition to the inclined position in the standby state is eliminated, thereby simplifying the electrical control procedure of the waste discharge pipe (1) and reducing the electrical control failure rate, and it is also advantageous to improve control precision by reducing the rotational error accumulated during the long-term use of the waste discharge pipe (1).

[0091] In one exemplary embodiment, as illustrated in FIG. 16, the waste discharge control method after step S104 may also include the following steps.

[0092] Step S106: Control to reset the waste discharge pipe to its initial position;

[0093] Step S108: Controls the brush ring flush device to continuously flush water to the bowl surface of the toilet body, thereby forming a watertight seal inside the toilet and completing one waste discharge cycle.

[0094] In this way, when waste is discharged, the waste discharge pipe (1) is automatically reset to its initial position. Additionally, the brush ring flush device (42) continuously flushes water to the bowl surface of the toilet body (4) to form a watertight seal inside the toilet, waiting for the next use.

[0095] It can be understood that the bowl surface of the toilet body refers to the inner wall surface of the bowl portion (41) of the toilet body (4), and can also be referred to as the internal cleaning surface of the toilet.

[0096] In one exemplary embodiment, the brush ring flush device (42) is controlled to continuously flush water to the bowl surface of the toilet body (4) to form a water seal inside the toilet.

[0097] It includes controlling the brush ring flush device (42) to continuously flush water to the bowl surface of the toilet body (4) until the water level inside the toilet bowl is higher than the lowest point of the overflow port (115), and then turning off the brush ring flush device (42) to lower the water level inside the toilet bowl so that it is aligned with the lowest point of the overflow port (115) through the overflow to form a water seal.

[0098] In the water replenishment step after the waste discharge operation is completed, the brush ring flush device (42) is turned off only after the water level inside the toilet bowl is higher than the lowest point of the overflow port (115), thereby aligning the water seal finally formed inside the toilet bowl with the lowest point of the overflow port (115) and ensuring that it is not lower than the overflow port (115), and thus, the height of the water seal surface inside the toilet bowl can be avoided so that odors overflow due to being too low.

[0099] In one exemplary embodiment, the brush ring flush device (42) is controlled to continue flushing water to the bowl surface of the toilet body (4) until the water level in the toilet bowl is higher than the lowest point of the overflow port (115), and then the brush ring flush device (42) is turned off.

[0100] When the waste discharge pipe (1) is reset to its initial position, a water replenishment time count starts, and when the water replenishment period reaches the set time, the brush ring flush device (42) is turned off.

[0101] Since the shape of the toilet body (4) and the waste discharge pipe (1) is fixed, the volume of water required to form a water seal is also fixed. During the design process, the minimum water replenishment period required from when the waste discharge pipe (1) is reset until the water seal is formed can be determined through a time count, and if the water replenishment period during the usage process is longer than the minimum water replenishment period during the test process, it can be guaranteed that the toilet water seal surface is higher than the lowest point of the overflow port (115). Therefore, the set time can be installed to be greater than the minimum water replenishment period during the test.

[0102] Controlling the off of the brush ring flush device (42) over time is advantageous for simplifying the electrical control procedure and further lowering the electrical control failure rate.

[0103] In another exemplary embodiment, the brush ring flush device (42) is controlled to continue flushing water to the bowl surface of the toilet body (4) until the water level in the toilet bowl is higher than the lowest point of the overflow port (115), and then the brush ring flush device (42) is turned off.

[0104] When the waste discharge pipe (1) is reset to its initial position, the discharge amount of the brush ring flush device (42) is monitored, and when the discharge amount of the brush ring flush device (42) reaches a set discharge amount, the brush ring flush device is turned off.

[0105] Since the shape of the toilet body (4) and the waste discharge pipe (1) is fixed, the volume of water required to form a water seal is also fixed. During the design process, the minimum water discharge volume required from the time the waste discharge pipe (1) is reset until the water seal is formed can be determined through flow rate measurement. If the water replenishment discharge volume during use is greater than the minimum discharge volume during the test process, it can be ensured that the toilet water seal surface is higher than the lowest point of the overflow port (115). Therefore, the set discharge volume can be set to be greater than the minimum discharge volume during the test process.

[0106] Compared to controlling the off of the brush ring flush device (42) over time, this method controls the off of the brush ring flush device (42) through flow rate, which is advantageous for high reliability and saving water.

[0107] In one exemplary embodiment, during one dirt discharge cycle, the brush ring flush device (42) continues to discharge water from when it is turned on until it is turned off.

[0108] The brush ring flush device (42) of a standard toilet generally only releases water during the initial stage, and its main function is to wet the inner wall surface (i.e., the bowl surface of the toilet body) of the toilet bowl (41) to dislodge the dirt stuck on the inner wall surface of the bowl (41). After that, the brush ring flush device is turned off, and the spray device located opposite the dirt discharge outlet (411) of the toilet body (4) is turned on to flush away the dirt using the high-speed, high-flow water stream of the spray device.

[0109] In the embodiment of the present disclosure, the brush ring flush device (42) is continuously turned on in the initial stage, the waste discharge stage, and the water replenishment stage. In the initial stage, it serves to increase the wetness and water-sealing surface, in the waste discharge stage, it serves to increase the gravitational energy of the waste, and in the water replenishment stage, it serves to supply water for water sealing. Therefore, the continuous inflow of water to the brush ring flush device (42) is advantageous for improving waste discharge performance and is also advantageous for simplifying the electrical control procedure of the toilet.

[0110] In an exemplary embodiment, in one waste discharge cycle,

[0111] Before the discharge pipe (1) rotates (i.e., in the initial stage), the on period of the brush ring flush device (42) is within the range of 5s to 6s, for example, 5s, 5.2s, 5.4s, 5.5s, 5.6s, 5.8s, 6s, etc.;

[0112] The period between when the waste discharge pipe (1) starts rotating and when the waste discharge pipe (1) starts resetting rotation (i.e., the waste discharge stage) is within the range of 3s to 8s, for example, 3s, 4s, 5s, 6s, 7s, 8s, etc.;

[0113] The period between when the waste discharge pipe (1) starts to reset and when the brush ring flush device (42) turns off (i.e., the water replenishment stage) is within the range of 4s to 10s, for example, 4s, 5s, 6s, 7s, 8s, 9s, 10s, etc.

[0114] By limiting the flush period of each stage of the brush ring flush device (42) to within the specified range during the waste discharge cleaning process through verification, as little water resources as possible can be used on the basis of effectively cleaning the inner wall surface of the bowl section (41) and the waste discharge pipe (1). In this way, not only can the waste discharge effect be avoided because the flush period is too short, but the waste of water resources can also be avoided because the flush period is too long and too much water is used.

[0115] Of course, the duration of each stage described above is not limited to the specified scope and can be adjusted as needed.

[0116] In one exemplary embodiment, when rotated from the initial position to the waste discharge position, the rotation angle of the waste discharge pipe (1) is within the range of 100° to 135°.

[0117] Compared to the waste discharge pipe (1) rotating 180° from top to bottom, if the rotation angle (B) of the waste discharge pipe (1) is limited to the range described above, not only can the demand for rotating waste discharge be satisfied, but the range of motion of the waste discharge pipe (1) can also be reduced, furthermore, the volume of the waste discharge box (2) can be reduced and the waste discharge box (2) can be miniaturized, and it is advantageous for improving the flexibility and suitability of the waste discharge system (10).

[0118] In addition, since the time node of the electric process for waste discharge has the greatest influence on the quality of the waste discharge effect, if the rotation range and time are too long, it is disadvantageous to the stability and consistency of the waste discharge effect. Therefore, limiting the rotation angle (B) of the waste discharge pipe (1) to within the above-described range is advantageous for shortening the movement time of the waste discharge pipe (1) and furthermore, can further stabilize the overall waste discharge effect.

[0119] Of course, when rotating from the initial position of waste discharge to the position of waste discharge, the rotation angle (B) of the waste discharge pipe (1) is not limited to the range described above and can be adjusted as needed.

[0120] In one exemplary embodiment, when the waste discharge pipe (1) is in its initial position, the waste discharge port (114) is oriented horizontally upward, as shown in FIGS. 9, 10, 11, and 12.

[0121] In this way, when the waste discharge pipe (1) is in its initial position and the brush ring flush device (42) is turned on, the watertight surface of the toilet can rise in alignment with the waste discharge port (114), allowing the internal space of the waste discharge pipe (1) to be fully utilized, which is advantageous for maximizing the gravitational energy of the liquid and waste inside the pipe, and furthermore, increasing the waste discharge efficiency and waste discharge effect.

[0122] In one exemplary embodiment, the waste discharge control method may also include the following.

[0123] After electricity is applied, the waste discharge pipe (1) is controlled to rotate from its position before electricity was applied to its initial position;

[0124] The brush ring flush device (42) is controlled to flush water to the bowl surface of the toilet body, thereby forming a water seal inside the toilet and entering a standby state.

[0125] Since the position of the waste discharge pipe (1) may change due to external force or other factors while the electricity is disconnected, after the electricity is turned on, the waste discharge pipe (1) is first rotated to its initial position and then the brush ring flush device (42) is turned on again to allow water to enter, which is advantageous for ensuring the accuracy of the subsequent water sealing surface position.

[0126] In one exemplary embodiment, the waste discharge control method also

[0127] It may include the step of checking whether the toilet enters a usage state or a washing standby state, and controlling the brush ring flush device (42) to flush to the bowl surface of the toilet body (4) to increase the water seal height of the toilet.

[0128] When it is detected that the toilet has entered the usage state or the standby state for flushing, it automatically initiates the waste disposal and cleaning process. Since there is no need for manual operation by the user, this improves the product's automation program and is advantageous for enhancing the user experience.

[0129] Here, when the toilet enters the usage state, it can enter the waste discharge cleaning process, and the inner wall surface of the toilet bowl (41) can be moistened to reduce the occurrence of waste getting stuck on the wall.

[0130] The toilet may only enter the waste disposal flushing process after it has entered the flushing standby state, which is advantageous for conserving water resources.

[0131] In one exemplary embodiment, in the step of checking whether the toilet enters a usage state or a flush standby state, a user’s sitting signal is detected to confirm that the toilet has entered a usage state, and a user’s exit signal is detected to confirm that the toilet has entered a flush standby state.

[0132] A detection device can be installed on the toilet seat ring, allowing confirmation that the toilet has entered a usage state when a user sits on the seat ring and the device's status changes. When the user finishes using the toilet and leaves the seat ring, the device's status also changes, confirming that the toilet has entered a standby state for flushing.

[0133] In one example, the seating and exiting signals include gravity signals. In this case, the detection device includes a gravity sensor, allowing the user to check the state of the toilet by detecting changes in the magnitude of gravity that occur when sitting or exiting.

[0134] In another example, infrared signals are included in the seating and exit signals. In this case, the detection device includes an infrared sensor, allowing the user to check the status of the toilet by detecting changes in the infrared signal that occur when sitting or exiting.

[0135] In one exemplary embodiment, the control method may also include receiving a cleaning command input from an external source.

[0136] After receiving a cleaning command input from the outside, the step of controlling the brush ring flush device (42) to flush water to the bowl surface of the toilet body (4) to increase the water seal height of the toilet is executed.

[0137] In other words, the user transmits a flush command via operation (e.g., pressing a remote control or the toilet's flush button), and the waste disposal flushing process begins only after the user's command is received. This solution ensures that the toilet can execute the waste disposal flushing procedure under the user's manual control, thereby satisfying the user's immediate needs.

[0138] As illustrated in FIG. 17, an embodiment of the present disclosure also provides a waste discharge control device, comprising a processor (504) and a memory (502) for storing a computer program, wherein the processor (504) implements a step of any one of the waste discharge control methods of the above-described embodiments when executing the computer program.
