Description

Technical Field

[0001] The present invention relates to the technical field of toilet flushing, and in particular to a toilet flushing method, a flushing device and a toilet. Background Art

[0002] At present, the flushing methods of smart toilets mainly include the following flushing methods according to water:

[0003] 1) Low water tank flushing, using the water potential in the water tank for direct flushing. Its disadvantage is that it completely relies on the gravitational potential energy of the water flow.

[0004] 2) Low water tank pump-assisted flushing: One solution uses a distribution valve, where the water pump pressurizes the water in the water tank and then delivers it to the distribution valve, which controls the brush circle water circuit and the jet water circuit respectively; the other solution uses an integrated flushing valve, where the brush circle water circuit is controlled by the flushing valve, and tap water is used directly for flushing, while the jet water circuit is pressurized by the water pump to ensure the flushing effect. The disadvantage is that the water pump of the distribution valve solution consumes a lot of power, and the water pump cannot work when the power is off, or an additional battery box is required to power the water pump for flushing. When the tap water pressure of the integrated flushing valve solution is low, the brush circle cannot be fully brushed, and the cleaning effect is poor.

[0005] 3) Tankless toilet: The wash water circuit and the jet water circuit both rely on the tap water pressure to work, and have certain requirements for the tap water flow and pressure. The disadvantage is that the flushing effect is poor when the flow and pressure do not meet the requirements. Summary of the invention

DETAILED DESCRIPTION

[0047] Embodiment 1

[0048] Combine the following Figure 1-Figure 2 The present invention is described in detail.

[0049] This embodiment provides a toilet flushing method for controlling a booster device 50 and a flushing valve 40. The boosted water after the booster device 50 is used to supply brush ring water and jet water at the same time. The flushing valve 40 is provided with a brush ring water path 403 and a jet water path 404. The brush ring water path 403 supplies brush ring water, and the jet water path 404 supplies the jet water path 404.

[0050] When the municipal power supply is used, as shown in 1, the booster device 50 is powered by the municipal power supply, and the brush ring water path 403 of the flush valve 40 remains open. After receiving the flushing instruction, the booster device 50 operates in the first state, the second state, and the third state for a certain period of time, respectively. The water flow rate of the booster device 50 in the first state and the third state is less than the water flow rate of the booster device 50 in the second state; wherein the first state is used to discharge the air in the pipeline and replenish the water seal inside the toilet 80, the second state is used to flush the wall of the toilet 80 and generate a siphon to take away the dirt, and the third state is used to replenish the water seal of the toilet 80 to play an anti-odor effect;

[0051] When there is no municipal power supply, as shown in Figure 2, the flushing valve 40 is powered by the energy storage device. After receiving the flushing instruction, the flushing valve 40 first opens the brush ring waterway 403 and supplies water for a time T1; closes the brush ring waterway 403, opens the spraying waterway 404 and supplies water for a time T2; closes the spraying waterway 404, and starts the brush ring waterway 403 again and supplies water for a time T3.

[0052] In the toilet flushing method proposed in this embodiment, when the municipal power supply is operating normally, the pressurizing device 50 supplies the brush ring water and the spraying water. The pressurizing device 50 operates in the first state, the second state, and the third state respectively during a flushing cycle, so as to complete the flushing under the municipal power supply; when there is no municipal power supply, the flushing valve 40 is powered by the energy storage device, and the brush ring water and the spraying water are supplied by the municipal water. During a flushing cycle, the flushing valve 40 sequentially opens the brush ring waterway 403 and the spraying waterway 404 according to a preset degree to complete the flushing without municipal power supply. This flushing method has the characteristics of good flushing performance with the assistance of the water pump. When there is no municipal power supply, the basic flushing requirements are realized through the flushing valve 40, solving the problem that the flushing method with the assistance of the water pump cannot be used in the power outage state, and expanding the application range of this toilet flushing method.

[0053] In this embodiment, the water outlet flow rate of the pressurizing device 50 in the first state to the third state is controlled by adjusting the duty cycle of the pressurizing device 50. Specifically, the pressurizing device 50 is a water pump with an adjustable duty cycle. The duty cycle is the ratio of the energization time to the total time. Therefore, the higher the duty cycle, the longer the energization time, and the higher the water outlet flow rate. The duty cycles of the pressurizing device 50 in the first state, the second state, and the third state are m1, m2, and m3 respectively. Therefore, when m1 < m3 and m2 < m3, the water outlet flow rates of the pressurizing device 50 in the first state and the third state are less than the water outlet flow rate of the pressurizing device 50 in the second state.

[0054] In other embodiments, the pressurizing device 50 is a water pump with an adjustable operating power, and different powers correspond to different rotational speeds. The rotational speeds of the pressurizing device 50 in the first state, the second state, and the third state are n1, n2, and n3 respectively. Therefore, when n1 < n3 and n2 < n3, the water outlet flow rates of the pressurizing device 50 in the first state and the third state are less than the water outlet flow rate of the pressurizing device 50 in the second state.
