[0002] This application relates to the field of toilet technology, and more particularly to a toilet. Background Technology

[0003] With the continuous development of science and technology, people's demands for living standards are constantly increasing, and this is reflected in all aspects of life. For example, regarding toilets, which are indispensable in daily life, users now not only expect toilets to have strong cleaning capabilities, but also to have an aesthetically pleasing design and not take up too much space. However, in actual use, miniaturized toilet designs have revealed some problems. The most significant of these is poor flushing performance, which is often directly related to the reduced diameter of the drain pipe caused by the smaller size of the toilet.

[0004] Many miniaturized toilet designs, in order to save space, have had to have their internal structures compacted while maintaining basic functionality. This includes a compact design for the drain pipe, such as reducing its diameter. While reducing the drain pipe diameter satisfies the need for space saving to some extent, it sacrifices water flow efficiency. This results in insufficient water flow during flushing, making it difficult to effectively remove waste, leading to incomplete flushing and clogging. Users of these toilets often need to flush multiple times to achieve the desired cleaning effect, wasting water and significantly reducing the user experience. Summary of the Invention

[0037] As mentioned in the background section, existing miniaturized toilet designs have poor sewage discharge performance.

[0038] To address the aforementioned technical problems, this application provides a toilet, comprising: a seat, including a waste collection tank, a water trap, and a drain pipe connected sequentially, wherein the inlet of the drain pipe is connected to the water trap, the water trap including a first wall away from the drain pipe and a second wall located below the first wall along the direction of gravity and connected to the inlet, the first wall having a through hole; and a bottom flush nozzle, the outlet of the bottom flush nozzle being disposed towards the inlet via the through hole, the centerline of the water jet sprayed by the bottom flush nozzle landing point being located on the drain pipe or the second wall, and the centerline of the outlet of the bottom flush nozzle being deflected at a first preset angle relative to the horizontal direction along the direction of gravity.

[0039] By adopting the technical solution of this application, the water jet sprayed by the bottom flush nozzle lands on the sewage pipe or the wall facing the direction of gravity. On the one hand, the water jet can be made to flow faster by taking advantage of gravity. On the other hand, the sewage pipe or the wall facing the direction of gravity near the sewage inlet is the part most prone to dirt blockage. The landing point of the sprayed water jet at this location can further optimize the flushing effect.

[0040] To make the above-mentioned objectives, features and beneficial effects of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0041] Figure 1 is a schematic diagram of a toilet according to an embodiment of this application, Figure 2 is a cross-sectional view of the seat in Figure 1 along the AA direction, and Figure 3 is a partial enlarged view of region B in Figure 2.

[0042] Referring to Figures 1 to 3, the toilet 100 may include: a seat 10, including a waste collection tank 12, a water trap 13, and a drain pipe 14 connected in sequence. The waste inlet 141 of the drain pipe 14 is connected to the water trap 13. The water trap 13 includes a first wall 131 facing away from the drain pipe 14 and a second wall 132 located below the first wall 131 along the gravity direction G and connected to the waste inlet 141. The first wall 131 has an opening 1311. A bottom flush nozzle 421 has its outlet facing the waste inlet 141 through the opening 1311. The center line of the water jet from the bottom flush nozzle 421 lands at either the drain pipe 14 or the second wall 132. The center line of the outlet of the bottom flush nozzle 421 is deflected by a first preset angle r relative to the horizontal direction along the gravity direction G.

[0043] Specifically, the seat 10 is the main structure of the toilet, and it includes a waste collection tank 12, a water trap 13, and a drain pipe 14. The waste collection tank 12 is the area where waste is temporarily stored for flushing. The water trap 13 is located between the waste collection tank 12 and the drain pipe 14. The water trap 13 acts as a water seal, preventing odors from returning to the bathroom environment through the drain pipe 14. The drain pipe 14 is the channel through which waste is flushed away, and its inlet 141 is connected to the water trap 13.

[0044] Furthermore, the water trap 13 includes a first wall 131 and a second wall 132. The first wall 131 is away from the sewage pipe 14, while the second wall 132 is located below the first wall 131 and is connected to the sewage inlet 141 of the sewage pipe 14.

[0045] In some embodiments, the second wall 132 may be, for example, the bottom wall of the water trap 13 along the gravity direction G.

[0046] Furthermore, an opening 1311 is provided on the first wall 131 to install the bottom flush nozzle 421 and expose the outlet of the bottom flush nozzle 421.

[0047] Furthermore, the bottom flush nozzle 421 sprays a water jet toward the sewage pipe 14 to flush away the dirt.

[0048] In some embodiments, the outlet of the bottom flush nozzle 421 is positioned toward the inlet 141 through an opening 1311 on the first wall 131 of the water trap 13.

[0049] Furthermore, the centerline of the water jet from the bottom-flush nozzle 421 lands at point j inside the drain pipe 14 or on the second wall 132. In other words, the water jet from the bottom-flush nozzle 421 is not directly directed horizontally towards the center of the sludge tank 12, but rather towards the bottom wall or second wall 132 of the drain pipe 14, which is more likely to accumulate sludge, facing the direction of gravity G, thereby improving flushing efficiency.

[0050] The centerline of the outlet of the bottom flush nozzle 421 is deflected by a first preset angle r relative to the horizontal direction along the direction of gravity G. This ensures that the landing point j is located on the bottom wall or the second wall 132 of the sewage pipe 14, and also helps the water column to better utilize the effect of gravity, increasing its flow rate and thus more effectively flushing away dirt.

[0051] In some embodiments, the first preset angle r is taken from [8°, 12°]. This ensures a better rinsing effect.

[0052] In some embodiments, the distance n between the landing point j of the center line of the water column and the sewage inlet 141 is less than a preset threshold.

[0053] In some embodiments, the preset threshold value is taken from [8, 10] mm. The specific value of the preset threshold may be related to the pipe diameter of the sewage pipe 14 and the size of the water trap 13.

[0054] In some embodiments, the width m of the water trap 13 in the horizontal direction is taken as [70, 80] millimeters. Thus, the smaller the width of the water trap 13 in the horizontal direction, the shorter the range of the water jet ejected by the bottom jet nozzle 421, thereby reducing the flow velocity loss of the water jet and ensuring that the water jet has sufficient thrust.

[0055] To verify the beneficial effects that the embodiments of this application can achieve, the applicant conducted corresponding simulation calculations.

[0056] Figure 6 is a schematic diagram of the old model in the simulation calculation; Figure 7 is a schematic diagram of the new model in the simulation calculation; Figure 8 is a schematic diagram of the change of water flow helix on the s1 surface with time in the new and old models in the simulation calculation; Figure 9 is a schematic diagram of the change of water pressure on the s1 surface with time (positive pressure) in the new and old models in the simulation calculation; Figure 10 is a schematic diagram of the change of water pressure on the s2 surface with time (negative pressure) in the new and old models in the simulation calculation; and Figure 11 is a table of simulation calculation data results.

[0057] Referring to Figures 6 to 11, in the old model used in the simulation calculation, the jet direction of the bottom-jet nozzle 421 is tilted upwards, which is basically consistent with the existing technology. In the new model, the jet direction of the bottom-jet nozzle 421 is tilted downwards, which is basically consistent with the embodiments shown in Figures 2 to 3 above. In Figures 8 and 9, the yellow lines represent the corresponding parameters of the new model, and the blue lines represent the corresponding parameters of the old model.

[0058] The simulation calculations are performed through the following steps.

[0059] First, select a first section s1 and a second section s2 in the sewage pipes 14 of both the new and old models. The first section s1 is located at the connection between the water trap 13 and the sewage pipe 14, and the second section s2 is located at the highest point of the sewage pipe 14.

[0060] Then, the integral of the helix of the s1 surface (m / s), the maximum pressure of the s1 surface (Pa), and the maximum pressure of the s2 surface (Pa) of the new model and the old model were measured and calculated respectively. The images shown in Figures 8 to 10 were plotted and the calculation results shown in Figure 11 were obtained.

[0061] Based on the results shown in Figures 8 to 10, generally, the larger the helicity and pressure values ​​on surface s1, the greater the flow channel thrust. Therefore, the new model is superior to the old model. The larger the negative pressure value on surface s2, the stronger the siphon. Therefore, the new model has better siphon performance than the old model.

[0062] It can be concluded from the above that, through the improvement of the structural parameters of the embodiments of this application, the angle and landing point of the water jet sprayed by the bottom flush nozzle 421 installed in the water trap 13 at the inlet of the sewage pipe 14 are optimized, ensuring better flow channel thrust and reducing backflow in the pipe, thereby improving the sewage discharge effect.

[0063] In some embodiments, the outlet of the bottom flush nozzle 421 is flush with the first wall 131, that is, the extension of the bottom flush nozzle 421 from outside the seat 10 into the seat 10 does not exceed the first wall 131. This prevents the bottom flush nozzle 421 from extending into the trap 14 and affecting the normal discharge of waste, and also prevents the bottom flush nozzle 421 from being positioned too far back, resulting in excessive loss of water flow velocity and insufficient thrust.

[0064] In some embodiments, the sludge tank 12, water trap 13, and drain pipe 14 of the seat 10 can all be made of ceramic material. The sludge tank 12, water trap 13, and drain pipe 14 made of ceramic material can have smooth walls to ensure the smooth discharge of waste.

[0065] In some embodiments, referring to FIG1, the toilet 100 may include a seat 10 and a cover assembly 20. The seat 10 has a mounting groove 11 and a waste collection groove 12, the mounting groove 11 being surrounded by the seat 10. A mounting bracket 30 is used to mount the cover assembly 20 onto the seat 10. The mounting bracket 30 is directly mounted onto the mounting groove 11 of the seat 10.

[0066] Furthermore, referring to Figures 1 and 4, the cover assembly 20 includes an upper cover 21, a seat ring 22, and a base 23. The upper cover 21 is located above the seat ring 22, and the upper cover 21 and the seat ring 22 are rotatably mounted to the base 23.

[0067] In some embodiments, the seat 10 may be made of ceramic or resin. The cover 21 may be a traditional toilet seat (i.e., a toilet seat that only covers the sludge tray 12 of the toilet) or an electronic toilet seat (or "smart toilet seat"), and the electronic toilet seat may provide various types of functions such as toilet cleaning, drying, disinfection, and heating according to user needs.

[0068] Furthermore, the waste collection trough 12 has an appropriate size and shape to facilitate user toilet use. The waste collection trough 12 typically includes a waste-collecting surface and a drain outlet located at the bottom of the trough. It is understood that the waste-collecting surface (also referred to as the inner wall of the waste collection trough or the waste receiving surface) extends downward from the top of the waste collection trough 12 and converges to the drain outlet, which is connected to a water trap 13. Waste is flushed from the drain outlet through the water trap 13 to the inlet 141 of the sewage pipe 14.

[0069] Furthermore, the mounting bracket 30 includes a mounting plate 31 and at least one mounting cavity 32 for mounting functional components. The mounting cavity 32 is integrated with the mounting plate 31 and can be closed or open. When the mounting cavity 32 is closed, it may have through holes for connecting other components.

[0070] Referring again to Figure 4, the mounting bracket 30 includes a first mounting cavity 321 and a second mounting cavity 322. The first mounting cavity 321 and the second mounting cavity 322 are located on opposite sides of the mounting plate 31 and are integrated with it, meaning the first mounting cavity 321 and the second mounting cavity 322 are integrally formed with the mounting plate 31. The base 10 includes a first mounting groove 111 and a second mounting groove 112, which are spaced apart by a certain distance. The base 10 surrounds the first mounting groove 111 and the second mounting groove 112. The first mounting groove 111 is used to mount the first mounting cavity 321, and the second mounting groove 112 is used to mount the second mounting cavity 322.

[0071] Referring to Figures 1, 4, and 5, in some embodiments, the mounting plate 31 of the mounting bracket 30 is provided with multiple fixing posts 311, which are detachably mounted and fixed to the mounting plate 31. The base plate 231 of the base 23 of the cover assembly 20 is provided with multiple fixing holes 2311 that are respectively interference-fitted with the multiple fixing posts 311. The position of the fixing posts 311 on the mounting plate 31 is adjustable. For example, the mounting and fixing position of the fixing posts 311 can be adjusted with reference to the position of the fixing holes 2311. Each fixing post 311 is provided with at least one annular groove 3111. In the embodiment shown in the figures, two annular grooves 3111 are provided. Each annular groove 3111 is provided with an elastic ring 3112, which can be a rubber ring. Relying on the elastic deformation of the elastic ring 3112, the self-tightening connection between the fixing posts 311 of the mounting bracket 30 and the fixing holes 2311 of the base 23 can be ensured. The operation is simple and reliable, and it can also meet the connection requirements from top to bottom.

[0072] Furthermore, the mounting plate 31 of the mounting bracket 30 is provided with multiple mounting holes 312. When the mounting bracket 30 is directly installed onto the mounting groove 11 of the base 10, the first mounting cavity 321 and the second mounting cavity 322 are respectively installed into the first mounting groove 111 and the second mounting groove 112. The mounting plate 31 is placed horizontally on the base 10, and the mounting plate 31 is fixed to the base 10 by fasteners such as screws passing through the mounting holes 312, thereby fixing the mounting bracket 30 to the base 10. Then, the fixing holes 2311 on the base 23 of the cover assembly 20 are aligned with the fixing posts 311 on the mounting plate 31 and installed from top to bottom. The position and number of fixing posts 311 on the mounting bracket 31 can be adjusted according to actual needs. The entire connection structure is compact, easy to assemble and disassemble, and highly adaptable.

[0073] In some embodiments, the toilet 100 includes a flushing conduit for flushing the sludge basin 12. Advantageously, the flushing conduit may include a circumferential flushing conduit 41 having circumferential flushing nozzles 411. The circumferential flushing conduit 41 is used to circumferentially flush the sludge basin 12, primarily its sludge-holding surface. A flushing port may be provided on the upper inner edge of the sludge basin 12, through which flushing water from the circumferential flushing conduit 41 flows into the sludge basin 12 for circumferential flushing. During circumferential flushing, the flushing water washes the sludge-holding surface from top to bottom to thoroughly clean the surface without leaving any blind spots.

[0074] In some embodiments, the wall of the sludge tank 12 may be provided with a mounting hole 121, through which the flushing nozzle 411 can flush the sludge tank 12.

[0075] In some embodiments, the structure of the dirt-holding surface is configured to facilitate water flow rotation (also known as "vortex discharge"), so that the water flowing from the flushing port swirls as it washes over the dirt-holding surface from top to bottom, thereby cleaning the dirt-holding surface and the dirt-holding tank more thoroughly. It is conceivable that the flushing port may also be located directly at any suitable location on the dirt-holding surface along the middle of the dirt-holding tank from top to bottom.

[0076] In some embodiments, the flushing line further includes a bottom flushing line 42, wherein the bottom flushing nozzle 421 is disposed on the bottom flushing line 421. It is understood that even if the ring flushing line 41 and the bottom flushing line 42 may have a portion of a common extension, this does not change the fact that the ring flushing line 41 and the bottom flushing line 42 are two independent lines.

[0077] In some embodiments, the toilet 100 further includes a flush valve 50 disposed within a mounting cavity 32 of the mounting bracket 30, such as a first mounting cavity 321. The flush valve 50 controls the flow of flushing water through it into the seat 10, primarily the sludge tray 12. In some embodiments, the flush valve 50 may be selectively in fluid communication with at least one of a flush line 41 and a bottom flush line 42, such that water for flushing flows through the flush valve 50 and the flush line 41 and / or the bottom flush line 42 to the sludge tray 12.

[0078] In some embodiments, the flush valve 50 may be an electrically controlled valve, such as an electro-hydraulic valve, meaning that the flush valve 50 can be opened or closed electrically. Preferably, the toilet flushing system has only one flush valve 50. When the flush valve 50 is open, water for flushing flows through the flush valve 50 into the flush pipe 41 and / or the bottom flush pipe 42, and then flows into the sludge collection tank 12 of the seat body 10 through the flush pipe 41 and / or the bottom flush pipe 42. In some embodiments, the flushing of the flush pipe 41 and / or the bottom flush pipe 42 can also be controlled by pre-setting a time period.

[0079] In some embodiments, the toilet 100 includes a first power supply device 60 disposed within a mounting cavity 32 of the mounting bracket 30, such as a second mounting cavity 322. The first power supply device 60 is configured to supply power to the flush valve 50.

[0080] In some embodiments, the toilet 100 includes a second power supply device (not shown) disposed within a mounting cavity 32 of the mounting bracket 30, for example, within a second mounting cavity 322. The second power supply device is connected to an external mobile power source or power adapter.

[0081] Furthermore, the first power supply device 60 can supply power to at least the flush valve 50 of the toilet 100, and can also supply power to other components besides the flush valve 50.

[0082] In some embodiments, the toilet 100 may include a tank, preferably a submerged tank (also referred to as a "built-in tank"), more preferably a tank that is completely submerged within the seat. When a submerged tank is used, the toilet 100 may also be referred to as a "low-profile" or "low-profile" toilet.

[0083] In some embodiments, the toilet 100 may further include a water pump 70, such as a booster pump. The flush valve 50 is provided with a first end connected to the outlet of the water pump 70, a second end connected to the flush nozzle 411 of the flush pipe 41, and a third end connected to the bottom flush nozzle 421 of the bottom flush pipe 42.

[0084] In some embodiments, an air isolation device may be provided between the first end and the second or third end of the flush valve 50 to prevent water from flowing back into the tank. This air isolation device prevents siphoning when the drain outlet of the tank is lower than the water level in the toilet bowl, which could cause dirty water to flow back into the tank. This ensures the cleanliness of the water stored in the tank, preventing mold and odor from forming due to sewage contamination, and thus reducing the frequency of tank cleaning by the user. Furthermore, a filter may be installed between the water inlet pipe and the flush valve 50, and the filter may be installed in the mounting cavity 32 of the mounting bracket 30.

[0085] In some embodiments, a flow distribution valve may be arranged upstream of the second and third ends of the flushing valve 50, for example at the first end of the flushing valve 50, so that the flow distribution valve can be used to select whether to communicate with the ring flushing nozzle 411 or the bottom flushing nozzle 421, thereby selecting whether water is discharged from the nozzle 411 or the bottom flushing nozzle 421 to meet the user's flushing needs and save water resources.

[0086] In some embodiments, the base 23 is provided with a pivot hole 232 for mounting a pivot, and the top cover 21 and the seat ring 22 are rotatably mounted to the base 23 via the pivot. Components such as a flush button 241 and a night light 242 can be mounted on the base 23. The flush button 241 has two water outlet buttons corresponding to different water volumes, and flushing is initiated by pressing the flush button 241 to activate the flush valve. Components such as a reducer 243, a damper 244, a control circuit board 245, a power adapter 246, and an emergency button 247 can also be mounted on the base 23. The reducer 243 and the damper 244 can slow down the falling speed of the top cover 21 and the seat ring 22.

[0087] Furthermore, the control circuit board 245 is connected to a power source via a power adapter 246. The functions of the control circuit board 245 include, but are not limited to: receiving signals from the toilet switch and issuing commands to supply power to the flush valve to initiate the flushing process; controlling the bottom flush line and / or circumferential flush line to control the timing, flushing water volume, and flushing time of the bottom flush or circumferential flush. An emergency button 247 is connected to an alarm system for sending an emergency signal.
