Description

Technical Field

[0001] This invention relates to the field of toilet technology, and more specifically to a toilet flushing system with a pump and a smart toilet. Background Technology

[0002] Currently, most toilet pump flushing systems on the market use a single power control module, meaning the toilet pump operates with the same power during both the flushing and refilling phases. This design has the following technical drawbacks:

[0003] 1. Because flushing and water replenishment share the same high-power mode, the water flow rate is too fast when replenishing the toilet water seal. It requires a large-capacity water tank to provide instantaneous high water volume support, resulting in redundant water tank volume, which goes against the current trend of miniaturization of bathroom products.

[0004] 2. The toilet pump continues to operate at flushing power during flushing, water replenishment, and shutdown, which generates high-frequency noise, especially at night, severely affecting the user experience.

[0005] 3. Not suitable for non-jet siphon flushing toilets. The turbulence generated by traditional high-power water replenishment will disrupt the critical pressure balance of the siphon and produce abnormal noise. Summary of the Invention

[0006] To address the above problems, the present invention provides the following technical solution:

[0007] A toilet flushing system with a pump includes a toilet with a bowl, a water tank and a water pump, and a washout port for flushing the bowl. The water pump is connected to the washout port. The period from the start to the stop of the water pump includes a first preset time period, a second preset time period and / or a third preset time period. During the first preset time period, the water pump operates at a first operating power to flush the toilet bowl. During the second preset time period, the water pump operates at a second operating power to replenish the toilet water seal. During the third preset time period, the water pump operates at a third operating power until the water pump stops. The first operating power is the maximum operating power.

[0008] The present invention is further configured such that: when the water pump is running in the first preset time period and the second preset time period, the second operating power of the water pump in the second preset time period is less than half of the first operating power in the first preset time period; when the water pump is running in the first preset time period, the second preset time period and the third preset time period, the third operating power of the water pump in the third preset time period is greater than half of the second operating power in the second preset time period.

[0009] The present invention is further configured as follows: the water pump is turned on and running, and during the first preset time period, the water pump runs at the first operating power and flushes the toilet bowl through the washing port to discharge toilet waste. After the water pump runs for the first preset time period T1, the water pump enters the second preset time period and runs at the second operating power, and replenishes water to the bottom of the toilet through the washing port to form a water seal. After the water pump runs for the second preset time period T2, the water pump enters the third preset time period and runs at the third operating power. After the water pump runs for the third preset time period T3, the water pump gradually reduces its power until it stops running.

[0010] The present invention is further configured such that: between each preset time period from the start of operation of the water pump to the stop of operation, there is an interval period, the interval period includes a first interval period and / or a second interval period, the first interval period is located between the first preset time period and the second preset time period, and the second interval period is located between the second preset time period and the third preset time period; the water pump remains in an on-state during the period from the start of operation of the water pump to the stop of operation of the water pump.

[0011] The present invention is further configured such that: the water pump includes an inlet end and an outlet end, the inlet end is connected to the drain outlet of the water tank, and the outlet end is connected to the washing port through an outlet pipe.

[0012] The present invention is further configured to include a water inlet valve, which is located in the water tank and supplies water to the water tank.

[0013] The invention is further configured such that: the water tank is located at the rear end of the toilet, and the water tank is detachably connected to the toilet.

[0014] The present invention is further configured such that: the water outlet pipe is an arc-shaped pipe, the water outlet pipe includes an inlet and an outlet, the outlet is higher than the inlet, and also includes a bend section located between the inlet and the outlet, the bend section being higher than the inlet and the outlet.

[0015] The present invention is further configured to include a control module, which is used to control the opening and closing of the water pump. The water pump includes a control system, which is used to control the rotational speed of the water pump, thereby controlling the outflow rate of the washing port.

[0016] In addition, the present invention also proposes an intelligent toilet, including the above-mentioned toilet flushing system with a pump.

[0017] Compared with the prior art, the present invention has at least the following advantages:

[0018] 1. This toilet flushing system includes multiple flushing modes. During the second preset time period, the water pump operates at the second operating power to replenish the toilet water seal. During the third preset time period, the water pump operates at the third operating power until the water pump stops. This means that the water flow is reduced during the replenishment phase, which can accurately restore the toilet water seal, reduce the requirements for the water tank capacity, reduce space occupation, and also reduce the noise at the end of the toilet flush, thus improving the user experience.

[0019] 2. The water pump adopts a second operating power water replenishment mode, which is suitable for siphon toilets that are sensitive to water flow. It avoids interference with siphon formation caused by traditional high-power water replenishment, and leaves no residue after flushing. It can realize a small volume water tank design and can be flexibly installed on new toilets such as wall-mounted and ultra-thin models. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0030] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] First embodiment:

[0032] This embodiment provides a toilet flushing system with a pump, such as... Figure 1 As shown, a toilet 1 includes a urinal 2. The toilet 1 is equipped with a water tank (not shown) and a water pump 4. It is also equipped with a washing port 3 for flushing the urinal 2 and a sewage pipe (not shown) connected to the bottom of the urinal 2. The water pump 4 is connected to the washing port 3. Water flows out from the washing port 3 and flushes into the urinal 2 along the washing channel, flushing the waste in the urinal 2 into the sewage pipe.

[0033] like Figures 2 to 5 As shown, in this embodiment, the period from the start of operation of the water pump 4 to its stop includes a first preset time period 8, a second preset time period 9, and a third preset time period 10. During the first preset time period 8, the water pump 4 operates at a first operating power to flush the toilet bowl 2 of the toilet 1. During the second preset time period 9, the water pump 4 operates at a second operating power to replenish the water seal of the toilet 1. During the third preset time period 10, the water pump 4 operates at a third operating power until the water pump 4 stops operating. The first operating power is the maximum operating power.

[0034] In this embodiment, when the water pump 4 is running in the first preset time period 8 and the second preset time period 9, the second operating power of the water pump 4 in the second preset time period 9 is less than half of the first operating power in the first preset time period 8. When the water pump 4 is turned on, it increases to the first operating power and then maintains the first operating power until the first preset time period 8 ends.

[0035] The operation of the water pump 4 includes the operation of the first preset time period 8, the second preset time period 9 and the third preset time period 10. During the third preset time period 10, the third operating power of the water pump 4 is greater than half of the second operating power during the second preset time period 9.

[0036] When water pump 4 is turned on, it operates at the first operating power during the first preset time period 8, flushing the toilet bowl 2 through the washing port 3 to remove waste from the toilet bowl 1. After water pump 4 has been running for the first preset time period 8T1, it enters the second preset time period 9 and operates at the second operating power, replenishing water to the bottom of the toilet bowl 1 through the washing port 3 to form a water seal. After water pump 4 has been running for the second preset time period 9T2, it enters the third preset time period 10 and operates at the third operating power. After water pump 4 has been running for the third preset time period 10T3, it gradually reduces its power until it stops operating.

[0037] The second preset time period 9 occurs after the toilet bowl 2 of toilet 1 has finished flushing. By significantly reducing the operating power of the water pump 4 and the water flow rate 6 of the washing port 3, the water flow during the replenishment phase is reduced. This not only accurately restores the water seal of toilet 1, but also ensures that the water inlet volume of the tank meets the flow requirements for replenishing the water seal. The tank does not need to support instantaneous high water volume, thus reducing the requirements for tank capacity and enabling a small-volume tank design. It can be flexibly installed in wall-mounted, ultra-thin, and other new types of toilets. The third preset time period 10 occurs after the water seal replenishment of toilet 1 has ended. The water pump 4 operates at a third power level, and the pump speed is further reduced until it gradually returns to zero. This eliminates water hammer pressure fluctuations in the pipeline, reduces the impact on the pipeline, and results in a lower failure rate over long-term use.

[0038] The water pump 4 includes interval periods between each preset time period from start to stop operation. These interval periods include a first interval period 11 and / or a second interval period 12. The first interval period 11 is located between a first preset time period 8 and a second preset time period 9, and the second interval period 12 is located between the second preset time period 9 and a third preset time period 10. During the first preset time period 8, the water pump 4 operates at a first operating power. After the first interval period, the water pump 4 enters the second preset time period 9 and operates at a second operating power. After the second interval period, the water pump 4 enters the third preset time period 10 and operates at a third operating power until the water pump 4 stops operating. The water pump 4 remains in an on / off state during the entire period from start to stop operation.

[0039] The water pump 4 includes an inlet end and an outlet end. The inlet end is connected to the drain outlet of the water tank, and the outlet end is connected to the washing port 3 through the outlet pipe 5. When the water pump 4 is turned on, it draws water out of the water tank and flows out of the washing port 3 through the outlet pipe 5. The water flow rate 6 decreases sequentially during the three preset time periods in the toilet flushing process.

[0040] The toilet flushing system of this embodiment also includes a water inlet valve 7, which is located in the water tank and is used to supply water to the water tank.

[0041] In this embodiment, the water tank is located at the rear end of the toilet 1. The water tank is detachably connected to the toilet 1 and can be connected by fasteners such as screws and threaded holes.

[0042] In this embodiment, the water outlet pipe 5 is an arc-shaped pipe, including an inlet and an outlet. The outlet is higher than the inlet. It also includes a bend section located between the inlet and the outlet, which is higher than both the inlet and outlet. By incorporating the bend section, the water outlet pipe 5 can further enhance the flushing intensity of the toilet and effectively prevent sewage from flowing back into the tank from the flushing outlet when the toilet is clogged.

[0043] The toilet flushing system in this embodiment also includes a control module, which controls the opening and closing of the water pump 4. The water pump 4 includes a control system, which controls the operating power of the water pump 4, thereby controlling the rotation speed of the water pump 4 and adjusting the water flow rate 6 at the washing outlet 3, so as to realize the phased control of the power of the water pump 4 during the flushing process. In this embodiment, the control system controls the water pump 4 to operate within 2 seconds from the start to the start of the first preset time period 8. The time T1 of the first preset time period 8 is 3 to 5 seconds, the time T2 of the first interval time period 11 is 0.3 to 0.6 seconds, the time T2 of the second preset time period 9 is 2 to 4 seconds, the time T2 of the second interval time period 12 is 0.1 to 0.5 seconds, the time T3 of the third preset time period 10 is 1 to 3 seconds, and the time from the end of the third preset time period 10 to the complete stop of the water pump 4 is within 0.6 seconds.

[0044] The working process of this invention is as follows:

[0045] After the user presses the flush button or the sensor detects a flushing demand, the control module starts the water pump 4. During the first preset time period 8, the water pump 4 runs at full speed with the first operating power. The high-speed water jet is sprayed out from the washing port 3 and forms a vortex-shaped water flow along the washing channel to flush the inner wall of the toilet bowl 2, flushing away the waste in the toilet bowl 2 through the bottom drain pipe. During the second preset time period 9, the water pump 4 runs at a second operating power that is reduced to less than half of the first operating power. The water flow speed decreases, and the low-speed water flow continuously injects water into the bottom of the toilet bowl 2 to replenish water and form a water seal. At the same time, the inlet valve 7 opens to replenish water into the water tank. During the third preset time period 10, the water pump 4 runs at a third operating power that is further reduced to more than half of the second operating power but does not exceed the second operating power. After the water pump 4 maintains this for a short time, it stops. After the water tank is replenished, the inlet valve 7 also closes.

[0046] Second embodiment:

[0047] This embodiment describes a toilet flushing system with a pump, such as... Figure 6As shown, in this embodiment, the period from the start of operation to the stop of operation of the water pump 4 includes a first preset time period 8 and a second preset time period 9, with a first interval time period 11 between the first preset time period 8 and the second preset time period 9. The operating parameters of the water pump 4 from start to end of the second preset time period 9 are the same as those in the first embodiment. The difference from the first embodiment is that the water pump 4 stops slowly directly after the second preset time period 9 ends.

[0048] The remaining undescribed parts are the same as in the first embodiment and will not be repeated here.

[0049] Third embodiment:

[0050] This embodiment describes a toilet flushing system with a pump, such as... Figure 7 As shown, in this embodiment, the period from the start to the stop of operation of the water pump 4 includes a first preset time period 8 and a third preset time period 10, with a third interval time period 13 between the first preset time period 8 and the third preset time period 10. The operating parameters of the water pump 4 in the first preset time period 8 and the third preset time period 10 are the same as in the first embodiment. The difference from the first embodiment is that after the first preset time period 8 ends, the water pump 4 directly reduces from the first operating power to the third operating power during the third interval time period 13, allowing the user to replenish the toilet water seal in another way.

[0051] The remaining undescribed parts are the same as in the first embodiment and will not be repeated here.

[0052] Fourth embodiment:

[0053] A smart toilet, not shown, includes a toilet flushing system with a pump as described in any of the above embodiments.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present invention should be included within the protection scope of the present invention.
