The toilet body is provided with a water storage tank and a toilet bowl. The bottom of the toilet bowl is provided with a first flushing opening, and the washing ring of the toilet bowl is provided with a second flushing opening. The flushing device comprises a water driving power element, a first flushing pipeline, a second flushing pipeline and a third flushing pipeline. The two ends of the first flushing pipeline are connected with the water storage tank and the first flushing opening respectively. The two ends of the second flushing pipeline are connected with the water driving power element and the second flushing opening respectively. The two ends of the third flushing pipeline are connected with the water driving power element and the first flushing pipeline respectively. The water driving power element can ensure the flushing power and improve the flushing effect. The second flushing pipeline still maintains flushing for a period of time after the flushing of the first flushing pipeline is completed, so that the water of the second flushing opening blocks the water flowing back from the sewage pipeline and impacts the wall surface at the first flushing opening to generate noise, thereby effectively reducing the flushing noise of the toilet and improving the use experience.

Description

Technical Field

[0001] This invention relates to the field of bathroom technology, and in particular to a silent toilet and its control method. Background Technology

[0002] The water tank of a conventional toilet is generally higher than the ceramic seat surface to ensure that the water in the tank has sufficient gravitational potential energy. When flushing, the water stored in the tank can provide greater potential energy to ensure flushing effect. However, due to the greater potential energy, the flushing noise is also greater, resulting in a poor user experience.

[0003] Therefore, there is an urgent need for a silent toilet and its control method to solve the above problems. Summary of the Invention

[0004] Based on the above problems, the purpose of this invention is to provide a silent toilet and its control method, which can reduce the noise of the toilet during flushing and improve the user experience.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] On the one hand, a silent toilet is provided, including:

[0007] The toilet body is equipped with a water tank and a toilet bowl. The bottom of the toilet bowl is equipped with a first flushing port, and the wash ring of the toilet bowl is equipped with a second flushing port.

[0008] A flushing device includes a water-driving power component, a first flushing pipe, a second flushing pipe, and a third flushing pipe.

The inlet end of the first flushing pipe is selectively connected to the water storage tank, and the outlet end of the first flushing pipe is connected to the first flushing port.

[0009] The inlet end of the second flushing pipe is connected to the outlet end of the water-driving power component, and the outlet end of the second flushing pipe is connected to the second flushing port.

[0011] As an optional embodiment of the silent toilet of the present invention, the third flushing pipe extends at least partially into the first flushing pipe, and the water outlet direction of the third flushing pipe is the same as the water flow direction in the first flushing pipe.

[0012] As an optional embodiment of the silent toilet of the present invention, the silent toilet further includes a drain valve, which is installed at the water inlet end of the first flushing pipe and is used to control the opening and closing of the first flushing pipe.

One end of the spray pipe is located in the valve cavity of the valve seat and is connected to the second end of the connecting channel. The other end of the spray pipe is provided with a nozzle. The nozzle is located in the first flushing pipeline, and the extension direction of the nozzle is the same as the extension direction of the first flushing pipeline.

[0014] As an optional embodiment of the silent toilet of the present invention, the silent toilet further includes a water inlet power component, the water inlet end of which is connected to a water supply pipe for water supply, and the water outlet end of which is connected to the water storage tank. The water inlet power component is configured to replenish water to the water storage tank.

[0015] Alternatively, the silent toilet may also include a water inlet valve disposed in the water storage tank, the water inlet end of the water inlet valve being connected to a water supply pipeline for water supply, and the water inlet valve being configured to replenish water to the water storage tank.

[0016] As an optional embodiment of the silent toilet of the present invention, the water inlet valve is provided with an air replenishment channel, and the flushing device further includes an exhaust pipe. The air inlet end of the exhaust pipe is connected to the first flushing pipe, and the air inlet end of the exhaust pipe is located on the side of the water inlet end of the first flushing pipe. The exhaust end of the exhaust pipe is connected to the air replenishment channel.

[0017] As an optional embodiment of the silent toilet of the present invention, the top surface of the water tank is not higher than the top surface of the toilet bowl, and the highest liquid level of the water tank is lower than the height of the second flushing port on the toilet bowl.

[0018] And / or, the bottom of the toilet bowl is provided with a drain outlet, the first flushing outlet is connected to the drain outlet, the toilet bowl forms a water cover above the drain outlet, and the lowest liquid level of the water storage tank is higher than the water cover.

[0019] And / or, the diameter of the first flushing outlet is D1, and the value of D1 is in the range of 25mm < D1 ≤ 30mm;

[0020] And / or, the diameter of the second flushing outlet is D2, and the value of D2 is in the range of 11mm < D2 ≤ 13mm;

[0021] And / or, the toilet bowl is provided with an installation port at the wash ring, and the flushing device further includes a flushing accessory installed at the installation port, the inlet end of the flushing accessory being connected to the outlet end of the second flushing pipe, and the outlet end of the flushing accessory forming the second flushing port.

[0022] As an optional embodiment of the silent toilet of the present invention, the vertical distance between the lowest liquid level of the water tank and the water surface is H1, and the value of H1 is in the range of 0mm < H1 ≤ 25mm.

[0023] As an optional embodiment of the silent toilet of the present invention, the water-driving power component includes a first power component and a second power component, wherein the water outlet of the first power component is connected to the water inlet of the second flushing pipe, and the water outlet of the second power component is connected to the water inlet of the third flushing pipe.

[0024] Alternatively, the water-driving power component has a first water outlet and a second water outlet, the first water outlet being connected to the water inlet of the second flushing pipe, and the second water outlet being connected to the water inlet of the third flushing pipe.

[0025] Secondly, a method for controlling a silent toilet is provided, applied to the silent toilet described above, the method comprising the following steps:

[0026] The first flushing pipe and the second flushing pipe are controlled to flush simultaneously; or, after the first flushing pipe has been flushed for a first preset time t1, the second flushing pipe is controlled to flush.

[0027] After the first flushing pipe has been flushed for a second preset time t2, the third flushing pipe is controlled to flush.

[0028] After the first or third flushing pipe finishes flushing, a third preset time t3 is elapsed, and the second flushing pipe is controlled to stop flushing.

[0029] As an optional solution to the silent toilet control method of the present invention, the first preset duration t1 is in the range of 0.5s≤t1≤2s;

[0030] And / or, the value range of the second preset duration t2 is 0.5s≤t2≤1s;

[0031] And / or, the value range of the third preset duration t3 is 0.5s≤t3≤3s.

[0032] The beneficial effects of this invention are as follows:

[0033] The silent toilet provided by this invention features a flat and aesthetically pleasing top because the top surface of the water tank is no higher than the top surface of the toilet bowl, while also saving space. When flushing, water from the water tank flows through the first flush pipe and the first flush nozzle to wash the bottom of the toilet bowl. Under the action of the water-driving mechanism, water from the water tank flows through the second flush pipe and the second flush nozzle to wash the washbasin and walls of the toilet bowl, thus flushing the bowl and allowing the water flow to carry away waste through the toilet's drain pipe. Simultaneously, under the action of the water-driving mechanism, water from the water tank flows through the third flush pipe to the first flush pipe, allowing the water-driving mechanism to assist the water in the first flush pipe, ensuring sufficient flushing force to wash the bottom of the toilet bowl and guaranteeing a good flushing effect. Furthermore, since the outlet of the third flush pipe is located on the same side as the inlet of the first flush pipe, the water flow generated by the third flush pipe will not directly impact the toilet bowl, and there is no need to design the size of the first flush outlet to be small. This prevents the water flow from impacting the wall at the first flush outlet and generating noise during flushing. In other words, while ensuring the flushing effect, flushing noise is avoided, thereby reducing the flushing noise of the toilet and improving the user experience.

[0034] The silent toilet control method provided by this invention controls the flushing of a third flushing pipe after a second preset time t2 following flushing through the first flushing pipe. That is, the third flushing pipe flushes later than the first flushing pipe, ensuring that the water output from the third flushing pipe does not interfere with the water entering the first flushing pipe from the storage tank, thus maintaining the flushing flow rate of the first flushing pipe. After a third preset time t3 following the completion of flushing through either the first or third flushing pipe, the second flushing pipe is controlled to stop flushing. That is, the flushing stop time of the second flushing pipe is later than that of the first or third flushing pipe. Since the backflow of water in the toilet's drain pipe will impact the wall of the first flushing outlet of the toilet bowl, the second flushing pipe continues to flush for a period of time after the first or third flushing pipe has finished flushing. This allows the water flow from the washbasin area to flow along the wall of the toilet bowl to the first flushing outlet, thus blocking the backflow of water in the drain pipe and preventing the backflow of water from impacting the wall of the first flushing outlet of the toilet bowl and generating noise. This effectively reduces the flushing noise of the toilet and improves the user experience. Attached Figure Description

[0063] Example 1

[0064] like Figures 1 to 12 As shown, this embodiment provides a silent toilet that can effectively reduce the noise during flushing and improve the user experience. The silent toilet includes a toilet body 1 and a flushing device 2.

[0065] Among them, see Figure 1 and Figure 2 The toilet body 1 is equipped with a water tank 11 and a toilet bowl 12. A first flushing inlet 121 is located at the bottom of the toilet bowl 12, and a second flushing inlet 51 is located at the wash ring 124 of the toilet bowl 12. (See reference...) Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The flushing device 2 includes a water-driving power component, a first flushing pipe 21, a second flushing pipe 22, and a third flushing pipe 23. The water-driving power component is located inside a water storage tank 11. The inlet end of the first flushing pipe 21 is selectively connected to the water storage tank 11, and the outlet end of the first flushing pipe 21 is connected to a first flushing port 121. The inlet end of the second flushing pipe 22 is connected to the outlet end of the water-driving power component, and the outlet end of the second flushing pipe 22 is connected to a second flushing port 51. The inlet end of the third flushing pipe 23 is connected to the outlet end of the water-driving power component, and the outlet end of the third flushing pipe 23 is connected to the first flushing pipe 21, with the outlet end of the third flushing pipe 23 located on the same side as the inlet end of the first flushing pipe 21.

[0066] The silent toilet provided in this embodiment, when flushed, the water in the water tank 11 flows through the first flush pipe 21 and the first flush outlet 121 to flush the bottom of the toilet bowl 12. Under the action of the water-driving power component, the water in the water tank 11 flows through the second flush pipe 22 and the second flush outlet 51 to flush the wash ring 124 and the wall of the toilet bowl 12, thus rinsing the toilet bowl 12 and causing the water flow to carry the waste out along the toilet's drain pipe 13. At the same time, under the action of the water-driving power component, the water in the water tank 11 flows through the third flush pipe 23 to the first flush pipe, so that the water-driving power component can assist the water in the first flush pipe 21, thereby giving the first flush pipe 21 sufficient flushing force to rinse the bottom of the toilet bowl 12 and ensuring the flushing effect. Furthermore, since the outlet of the third flush pipe 23 is located on the same side as the inlet of the first flush pipe 21, the water flow generated by the third flush pipe 23 will not directly impact the toilet bowl 12, and there is no need to design the size of the first flush outlet 121 to be small. This prevents the water flow from impacting the wall at the first flush outlet 121 during flushing and generating noise. In other words, while ensuring the flushing effect, flushing noise is avoided, thereby reducing the flushing noise of the toilet and improving the user experience.

[0067] Optionally, the top surface of the water tank 11 is not higher than the top surface of the toilet bowl 12, as shown in the reference. Figure 1 and Figure 2 In this context, the top surface of the water tank 11 and the top surface of the toilet bowl 12 refer to the surface above the toilet body 1, that is, the top surface when the toilet is in use after installation. Since the top surface of the water tank 11 is not higher than the top surface of the toilet bowl 12, the top of the toilet is flat, aesthetically pleasing, and saves floor space.

[0068] Optionally, the water tank 11 and the toilet body 1 are integrally formed and both are made of ceramic material. In other embodiments, the water tank 11 can also be designed separately from the toilet body 1, and the water tank 11 can be made of materials such as plastic.

[0069] Optionally, see Figure 5 , Figure 6 and Figure 7 The water-driving power components include a first power component 24 and a second power component 25. The outlet of the first power component 24 is connected to the inlet of the second flushing pipe 22, and the outlet of the second power component 25 is connected to the inlet of the third flushing pipe 23. That is, the first power component 24 provides power to the second flushing pipe 22, and the second power component 25 provides power to the third flushing pipe 23. The second flushing pipe 22 and the third flushing pipe 23 can be controlled independently. By controlling the flushing sequence of the second flushing pipe 22, the third flushing pipe 23, and the first flushing pipe 21, the flushing noise of the toilet can be further reduced.

[0070] Specifically, the third flushing pipe 23 can be controlled to flush later than the first flushing pipe 21 by the first power component 24 and the second power component 25, so that the water output of the third flushing pipe 23 will not interfere with the water in the water tank 11 entering the first flushing pipe 21, thus ensuring the flushing flow rate of the first flushing pipe 21. The first power component 24 can also control the flushing stop time of the second flushing pipe 22 to be later than the flushing stop time of the first flushing pipe 21 or the third flushing pipe 23. That is, the second flushing pipe 22 continues to flush for a period of time after the flushing of the first flushing pipe 21 or the third flushing pipe 23 has ended. This allows the water flow at the washbasin 124 to flow along the wall of the toilet bowl 12 to the first flush outlet 121, thus blocking the backflow of water in the drain pipe 13 and preventing the backflow of water in the drain pipe 13 from impacting the wall of the first flush outlet 121 of the toilet bowl 12 and generating noise. This effectively reduces the flushing noise of the toilet and improves the user experience.

[0071] For example, both the first power component 24 and the second power component 25 can be a water pump, a water pumping machine, etc.

[0072] In other alternative embodiments, the water-driving power component has a first water outlet and a second water outlet. The first water outlet is connected to the water inlet of the second flushing pipe 22, and the second water outlet is connected to the water inlet of the third flushing pipe 23. That is, the water-driving power component provides power to both the second flushing pipe 22 and the third flushing pipe 23, and can simultaneously control the flushing of both the second flushing pipe 22 and the third flushing pipe 23. For example, the water-driving power component can be a bidirectional output pump.

[0073] In the existing technology, some smart toilets have smaller flushing holes in order to ensure flushing pressure. When flushing, the water flow impacts the wall of the flushing hole, which also brings a lot of flushing noise and affects the user's experience.

[0074] In this embodiment, optionally, refer to Figure 8 and Figure 9 The third flushing pipe 23 extends at least partially into the first flushing pipe 21, and the water outlet direction of the third flushing pipe 23 is the same as the water flow direction in the first flushing pipe 21. This arrangement ensures that the water flow from the third flushing pipe 23 is aligned with the water flow in the first flushing pipe 21, effectively assisting the water flow in the first flushing pipe 21 and guaranteeing sufficient flushing force for the water jet from the first flushing nozzle 121. Therefore, with this design, there is no need to design the first flushing nozzle 121 to be small, preventing noise from the water jet impacting the wall at the first flushing nozzle 121 during flushing, reducing toilet flushing noise, and improving the user experience.

[0075] See Figure 6 , Figure 8 and Figure 9 The silent toilet also includes a drain valve 3, which is installed at the inlet end of the first flush pipe 21 to control the opening and closing of the first flush pipe 21. The drain valve 3 includes a valve seat 31. The third flush pipe 23 includes a connecting pipe 231 and a spray pipe 232. A connecting channel 312 is provided on the valve seat 31. One end of the connecting pipe 231 is connected to the outlet end of the water-driving power component, and the other end is connected to the first end of the connecting channel 312. One end of the spray pipe 232 is located in the valve cavity 311 of the valve seat 31 and is connected to the second end of the connecting channel 312. The other end of the spray pipe 232 is provided with a nozzle 2321, which is located in the first flush pipe 21 and extends in the same direction as the first flush pipe 21. That is, the part of the nozzle 232 located inside the first flushing pipe 21 has the same shape as the corresponding section of the nozzle 232 in the first flushing pipe 21, ensuring that the water outlet direction of the nozzle 2321 is consistent with the water flow direction in the first flushing pipe 21, so that the third flushing pipe 23 can effectively assist the water in the first flushing pipe 21, while reducing the degree of water flow turbulence and further reducing flushing noise.

[0076] In this embodiment, the connecting channel 312 is a pipe that runs through the side wall of the valve seat 31, with both ends of the pipe connected to the connecting pipe 231 and the nozzle 232, respectively. Further, the connecting pipe 231 is a flexible hose, which can adaptably deform to facilitate connection operations and allows for easy routing of the connecting pipe 231 within the water storage tank 11. The nozzle 232 is a rigid pipe, ensuring that the bending direction of the nozzle 232 is consistent with the bending direction of the first flushing pipe 21, guaranteeing that the water outlet direction of the nozzle 2321 is consistent with the water flow direction within the first flushing pipe 21. For example, the connecting pipe 231 can be a rubber hose, a soft plastic hose, etc., and the nozzle 2321 can be a rigid plastic hose or a metal hose, etc.

[0077] For example, the valve seat 31 is made of ceramic material, and the connecting channel 312 is a pipe integrally formed on the valve seat 31. In other embodiments, a through hole may be pre-drilled in the valve seat 31, and the pipe may be inserted and fixed to the through hole later.

[0078] See Figure 8 The drain valve 3 also includes a valve core 32, which is movably disposed on the valve seat 31. By driving the valve core 32 to move, the valve cavity 311 of the valve seat 31 can be opened or blocked, so that the inlet end of the first flushing pipe 21 can selectively connect to the water storage tank 11. In this embodiment, the valve core 32 can move up and down relative to the valve seat 31. By lifting the valve core 32, the drain valve 3 can be opened, and the water in the water storage tank 11 enters the valve cavity 311 and the first flushing pipe 21 under its own gravity.

[0079] See Figure 2 and Figure 10 The highest liquid level 111 of the water tank 11 is lower than the height of the second flushing nozzle 51 on the toilet bowl 12, ensuring that the water in the water tank will not overflow.

[0080] See Figure 4 and Figure 10 The toilet bowl 12 has a drain outlet 123 at its bottom, which is also the inlet of the drain pipe 13. The first flush outlet 121 is connected to the drain outlet 123, and a water surface 122 is formed above the drain outlet 123 on the toilet bowl 12. The lowest liquid level 112 of the water tank 11 is higher than the water surface 122. This arrangement ensures that the water in the water tank 11 has sufficient gravitational potential energy, so that when the drain valve 3 is opened, the water in the water tank 11 can smoothly and automatically enter the first flush pipe 21, ensuring that the water in the first flush pipe 21 has a certain impact force.

[0081] See Figure 10The vertical distance between the lowest liquid level 112 and the water surface 122 of the water storage tank 11 is H1, and the value of H1 is in the range of 0mm < H1 ≤ 25mm. This size design can ensure that the water in the tank has sufficient potential energy, and at the same time, it can maximize the capacity of the water storage tank 11 to ensure that there is enough water to flush the toilet.

[0082] For example, the value of H1 can be 1mm, 5mm, 8mm, 10mm, 15mm, 20mm, 25mm, etc.

[0083] Optionally, see Figure 4 and Figure 11 The diameter of the first flush nozzle 121 is D1, and the value of D1 ranges from 25mm to 30mm. This size design allows the first flush nozzle 121 to have a sufficiently large diameter, effectively controlling the water flow velocity from the first flush nozzle 121. This ensures that the water flow impact force meets the flushing requirements, while preventing the water flow velocity from being too high, thus avoiding noise generated by excessive water flow impacting the wall at the first flush nozzle 121 and reducing the flushing noise of the first flush pipe 21. Furthermore, the sufficiently large diameter of the first flush nozzle 121 increases the water spray volume, allowing the toilet to quickly generate a siphon effect, reducing siphon noise.

[0084] For example, the value of D1 can be 25mm, 26mm, 27mm, 28mm, 29mm, 30mm, etc.

[0085] Optionally, the diameter of the second flush nozzle 51 is D2, where D2 ranges from 11mm to 13mm. This size design, while meeting the requirements of water flow flushing force, allows the second flush nozzle 51 to have a sufficiently large diameter, controlling the water flow velocity at the second flush nozzle 51 within a suitable range. This prevents excessive water flow velocity from impacting the toilet bowl 12 wall and generating excessive noise, thereby reducing the flushing noise during the washing ring 124 flushing process.

[0086] For example, the value of D2 can be 11mm, 11.5mm, 12mm, 12.5mm, 13mm, etc.

[0087] Optionally, the toilet bowl 12 has an installation port at the wash ring 124, see reference. Figure 2 and Figure 5The flushing device 2 also includes a flushing accessory 5 installed at the installation port. The inlet end of the flushing accessory 5 is connected to the outlet end of the second flushing pipe 22, and the outlet end of the flushing accessory 5 forms a second flushing port 51. In this embodiment, the flushing accessory 5 is sealed and installed at the installation port, and the second flushing pipe 22 only needs to be plugged into the inlet end of the flushing accessory 5. Specifically, the flushing accessory 5 includes a sleeve and a stop and a locking part spaced apart on the sleeve. The locking part is detachably connected to the sleeve. When installing the flushing accessory 5, the locking part is removed from the sleeve, and the sleeve passes through the installation port from one side of the toilet bowl 12. The stop stops against the wall surface of the wash ring 124 of the toilet bowl 12. Then, the locking part is installed to the sleeve, so that the locking part and the stop cooperate to clamp the part between the toilet bowl 12 and the water tank 11, so that the flushing accessory 5 is firmly installed at the installation port.

[0088] For example, both the stop and the locking part are provided with sealing elements (such as rubber gaskets), and both the stop and the locking part can be sealed with both sides of the installation port through the sealing elements to prevent water leakage at the installation port. The second flushing pipe 22 can be a flexible hose (such as a rubber hose or a plastic hose), and the outlet end of the second flushing pipe 22 can be directly connected to the outside of the sleeve, making the connection operation convenient.

[0089] See Figure 2 The inner wall of the water storage tank 11 is provided with a support pipe clamp 14, which is used to support and fix the second flush pipe 22 so that the end of the second flush pipe 22 near the flush fitting 5 is roughly at the same height as the flush fitting 5, ensuring that the connection between the second flush pipe 22 and the flush fitting 5 will not be pulled and the connection is reliable.

[0090] Optionally, see Figure 1 and Figure 12 The silent toilet also includes a water inlet valve 4 installed in the water tank 11. The inlet end of the water inlet valve 4 is connected to a water supply pipe (such as the water supply pipe for the bathroom) and is configured to replenish water to the water tank 11. Specifically, the water inlet valve 4 has a first working liquid level 401 and a second working liquid level 402. When the first working liquid level 401 is lower than the second working liquid level 402, the water inlet valve 4 is open when the liquid level in the water tank 11 is lower than the first working liquid level 401, and the water inlet valve 4 is closed when the liquid level in the water tank 11 is higher than the second working liquid level 402. The stable liquid level in the water tank 11 corresponds to the second working liquid level 402, that is, the highest liquid level 111 in the water tank 11. When the liquid level in the water tank 11 is higher than the second working liquid level 402, the water inlet valve 4 is closed, which can prevent excessive water replenishment and avoid water overflow from the water tank 11. When the toilet is flushed, the water level in the water tank 11 decreases. Therefore, opening the inlet valve 4 can replenish the water tank 11 in time to ensure that the water level in the water tank 11 is sufficient.

[0091] Optionally, see Figure 12The height difference between the first working liquid level 401 and the second working liquid level 402 is H2, and the value of H2 is in the range of 28mm < H2 ≤ 35mm. This size design ensures that there is enough water in the tank to meet the needs of secondary flushing.

[0092] For example, the value of H2 can be 29mm, 30mm, 31mm, 32mm, etc.

[0093] See Figure 5 , Figure 6 and Figure 12 A water inlet 42 is provided below the water inlet valve 4. The water inlet 42 passes through the bottom of the water storage tank 11. The water supply pipeline is connected to the water inlet 42 so as to replenish the water storage tank 11 with water through the water inlet valve 4.

[0094] Optionally, see Figure 7 and Figure 9 The inlet valve 4 is equipped with an air replenishment channel 41. The flushing device 2 also includes an exhaust pipe 26. The air inlet of the exhaust pipe 26 is connected to the first flushing pipe 21, and the air inlet of the exhaust pipe 26 is located on the side of the water inlet of the first flushing pipe 21. The exhaust end of the exhaust pipe 26 is connected to the air replenishment channel 41. After the toilet is flushed, as the water cover 122 descends, some air will enter the first flushing pipe 21 from the first flush outlet 121. After the water cover 122 returns to its original position, this part of the air is compressed in the first flushing pipe 21. By setting the exhaust pipe 26, the air in the first flushing pipe 21 can be discharged from the exhaust pipe 26 in time, avoiding bubbling during the next flush. By connecting the exhaust pipe 26 to the air replenishment channel 41 of the inlet valve 4, when water enters the inlet valve 4, air can enter from the air replenishment channel 41 to balance the internal pressure of the inlet valve 4 and ensure the stable operation of the inlet valve 4.

[0095] See Figure 6 , Figure 7 and Figure 9 The valve seat 31 of the drain valve 3 is provided with an exhaust port 313. One end of the exhaust pipe 26 is sleeved with the exhaust port 313, and the other end is sleeved with the air supply channel 41. For example, the exhaust pipe 26 is a flexible hose (e.g., a rubber hose) to facilitate connection with the air supply channel 41 and the exhaust port 313.

[0096] Example 2

[0097] This embodiment provides a silent toilet, which differs from Embodiment 1 in that:

[0098] In this embodiment, the silent toilet also includes a water inlet power component. The inlet end of the water inlet power component is connected to a water supply pipe, and the outlet end of the water inlet power component is connected to a water storage tank 11. The water inlet power component is configured to replenish water to the water storage tank 11. When the water storage tank 11 needs to be replenished, the water inlet power component is activated, causing it to deliver water from the water supply pipe to the water storage tank 11. The water inlet power component can control the water flow rate within a suitable range, reducing water flow noise when replenishing the water storage tank 11 and further improving the user experience.

[0099] For example, the water inlet power component can be a water pump.

[0100] Example 3

[0101] This embodiment provides a silent toilet, which is a further improvement on the first embodiment. The main difference is:

[0102] See Figure 5 , Figure 6 and Figure 8 The silent toilet includes a drain valve 3 located at the inlet end of the first flush pipe 21. The first flush pipe 21 includes a first bend section 211, a straight section 212, and a second bend section 213 connected in sequence. The first bend section 211 is used to connect to the drain valve 3, and the second bend section 213 is used to connect to the first flush outlet 121. The straight section 212 is inclined, and its inlet end is higher than its outlet end. This arrangement allows water entering the first flush pipe 21 to flow along the inclined straight section 212 when the drain valve 3 is opened, reducing water flow resistance and ensuring sufficient flushing force at the first flush outlet 121, thus improving the toilet's flushing effect.

[0103] See Figure 8 The inclination angle of the straight pipe section 212 relative to the horizontal plane is defined as α, and the value of α ranges from 5° to 15°. For example, α can take values ​​of 5°, 6°, 8°, 10°, 12°, 15°, etc.

[0104] Optionally, the inner diameter of the straight pipe section 212 is D3, with a value ranging from 35mm to 45mm, to ensure that the inner diameter of the first flushing pipe 21 is large enough to further reduce flushing noise. For example, the diameter of the straight pipe section 212 can be 38mm, 40mm, or 42mm.

[0105] Optionally, the straight pipe section 212 is made of a different material than the first bend pipe section 211 and the second bend pipe section 213. In this embodiment, the straight pipe section 212 is a plastic pipe (e.g., a PVC pipe), while the first bend pipe section 211 and the second bend pipe section 213 are both rubber pipes. Plastic pipes and rubber pipes have low material costs, which helps to reduce the production cost of the toilet.

[0106] Optionally, see Figure 6 and Figure 9 The first bend section 211 and the second bend section 213 are both connected to the straight section 212 via the first pipe clamp 214. The first bend section 211 and the drain valve 3, and the second bend section 213 and the first flushing port 121 are both locked and fixed via the second pipe clamp 215, facilitating assembly. The lower end of the valve seat 31 of the drain valve 3 is provided with a first connecting part. The first bend section 211 is fitted over the first connecting part, and the first pipe clamp 214 is fitted over the first bend section 211, effectively clamping the first bend section 211 to the first connecting part. Figure 4 and Figure 10 As shown, a second connecting part 1211 is provided at the first flushing port 121 in the direction away from the sewage outlet 123. The second bend section 213 is sleeved on the second connecting part 1211. The first pipe clamp 214 is sleeved on the second bend section 213 and can tighten the second bend section 213 to the second connecting part 1211.

[0107] Optionally, the inlet size of the second bend section 213 is the same as that of the straight section 212, and the outlet size of the second bend section 213 is smaller than the inlet size. That is, the inner diameter of the second bend section 213 gradually decreases from the inlet to the outlet. This arrangement allows the water flow to be accelerated at the second bend section 213 to compensate for the flow velocity loss due to the bend, ensuring that the water jet at the first flushing port 121 has a moving impact force. For example, the inlet diameter of the second bend section 213 is 40 mm, and the outlet diameter is 30 mm.

[0108] See Figure 9 The outer wall of the second bend section 213, where it connects to the straight section 212, is inclined relative to the outer wall of the straight section 212, towards the axis of the straight section 212. The inclination angle of the outer wall of the second bend section 213 is defined as β, and the value of β ranges from 15° to 18°. This structural design allows the water flow reaching the second bend section 213 to transition more smoothly, reducing water flow velocity loss and further ensuring the water flow impact force at the first flushing inlet 121.

[0109] For example, β can take values ​​of 15°, 16°, 17°, 18°, etc.

[0110] Example 4

[0111] This embodiment provides a method for controlling a silent toilet, applicable to the silent toilet described in any of the above embodiments. The method for controlling a silent toilet includes the following steps:

[0112] S1. Control the first flushing pipe 21 and the second flushing pipe 22 to flush simultaneously; or, after the first flushing pipe 21 flushes for a first preset time t1, control the second flushing pipe 22 to flush.

[0113] S2, after the first flushing pipe 21 flushes for a second preset time t2, control the third flushing pipe 23 to flush;

[0114] S3. After the first flushing pipe 21 or the third flushing pipe 23 finishes flushing, after a third preset time t3, control the second flushing pipe 22 to stop flushing.

[0115] In one optional flushing scheme, while opening the drain valve 3, the water-driving power component is controlled to operate, so that the first flushing pipe 21 and the second flushing pipe 22 can flush at the same time, that is, the bottom of the toilet bowl 12, the wash ring 124 of the toilet bowl 12, and the wall surface of the toilet bowl 12 are flushed at the same time.

[0116] In another alternative flushing scheme, the drain valve 3 can be opened first to flush the first flushing pipe 21. After a first preset time t1, the water driving power component can be controlled to activate the second flushing pipe 22, which flushes later than the first flushing pipe 21. This can also flush the bottom and side walls of the toilet bowl 12.

[0117] In this silent toilet control method, the third flushing pipe 23 flushes later than the first flushing pipe 21, ensuring that the water output from the third flushing pipe 23 does not interfere with the water entering the first flushing pipe 21 from the water tank 11, thus maintaining the flushing flow rate of the first flushing pipe 21. The flushing stop time of the second flushing pipe 22 is later than the flushing stop time of the first flushing pipe 21 or the third flushing pipe 23. That is, the second flushing pipe 22 continues to flush for a period of time after the first flushing pipe 21 or the third flushing pipe 23 has finished flushing. This allows the water flow at the wash seat 124 to flow along the wall of the toilet bowl 12 to the first flush outlet 121, blocking the backflow of water in the drain pipe 13 and preventing the backflow of water in the drain pipe 13 from impacting the wall of the first flush outlet 121 of the toilet bowl 12 and generating noise. This effectively reduces the flushing noise of the toilet and improves the user experience.

[0118] In steps S1, S2 and S3, the opening and closing of the first power component 24 controls whether the second flushing pipe 22 flushes, and the opening and closing of the second power component 25 controls whether the third flushing pipe 23 flushes.

[0119] Optionally, the first preset duration t1 can be in the range of 0.5s ≤ t1 ≤ 2s. For example, t1 can be 0.7s, meaning the second flushing pipe 22 starts flushing 0.7s later than the first flushing pipe 21. In other embodiments, t1 can also be 0.6s, 0.8s, 1s, 1.2s, 1.5s, 2s, etc.

[0120] Optionally, the second preset duration t2 is in the range of 0.5s≤t2≤1s. Within this time range, the third flushing pipe 23 is controlled to flush later than the first flushing pipe 21, which can both accelerate the water flow in the first flushing pipe 21 and avoid interfering with the initial water intake of the first flushing pipe 21, thus ensuring the water flow rate in the first flushing pipe 21.

[0121] For example, t2 can be 0.5s, meaning that the third flushing pipe 23 starts flushing 0.5s later than the first flushing pipe 21. In other embodiments, t2 can also be 0.6s, 0.8s, 0.9s, 1s, etc.

[0122] Optionally, the third preset duration t3 is in the range of 0.5s≤t3≤3s. Within this time range, controlling the second flushing pipe 22 to stop flushing later than the first flushing pipe 21 can effectively prevent the backflow of sewage pipe 13 from impacting the wall of the toilet bowl 12, effectively solving the noise generated when sewage pipe 13 backflows, and reducing the flushing noise of the toilet.

[0123] For example, t3 can be 0.6s, meaning that the second flushing pipe 22 stops flushing 0.6s later than the first flushing pipe 21. In other embodiments, t3 can also be 0.7s, 0.9s, 1s, 1.2s, 1.5s, 2s, 2.5s, etc.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention.
