Examples

Referring to fig. 1 to 7, the present embodiment provides a method for controlling flushing of a toilet, which is applied to a toilet flushing process. The device can effectively solve the problems of untimely and incomplete flushing of dirt caused by repeated water outlet stopping and long stopping time in the flushing process. The closestool comprises a closestool body 1, a closestool surface 2 formed on the closestool body 1 and a sewage discharge pipe 3 communicated with the bottom of the closestool body 1. A flushing waterway 4 for flushing the urinal surface 2 is arranged near the urinal surface 2, and a jet waterway 5 for jetting is arranged near the bottom of the toilet, and the flushing waterway 4 and the jet waterway 5 are controlled by a water outlet control unit 6 to open and close the water outlet and adjust the flow threshold of the water outlet.

The toilet flushing control method comprises the following steps:

s1: the water outlet control unit 6 drives the flushing waterway 4 to discharge water in a flow increasing mode until the flushing waterway 4 reaches a preset flow Q1, and after the flow is kept to discharge water continuously for a time T1, the flow of the flushing waterway 4 is instantly reduced to the preset flow Q2.

S2: the water spraying channel 5 is driven to spray water within the time T1, when the preset flow rate of the flushing channel 4 is Q2, the flow rate of the water spraying channel 5 is instantly increased to the preset flow rate Q3, and the toilet bottom is flushed to siphon the sewage discharging pipe 3.

S3: after keeping the flushing waterway 4 at the flow rate Q2 and the injection waterway 5 at the flow rate Q3 to continue to discharge water for the time T2, the flow rate of the flushing waterway 4 is instantaneously increased back to the flow rate Q1 and the flow rate of the injection waterway 5 is instantaneously decreased to the flow rate Q4, and the continuous discharge water is kept for the time T3.

S4: after the time T3, the flow rate of the flush water path 4 is instantaneously decreased to the flow rate Q5 and the flow rate of the injection water path 5 is instantaneously switched to the return flow rate Q3, so that the siphon formation of the sewage drain pipe 3 is performed again, and the discharge of the flush water path 4 and the injection water path 5 is stopped after the flow rate Q5 and the flow rate Q3 are continued to be different.

In the toilet flushing control method of the embodiment, when the flushing water path 4 is increased to the flow rate Q1, the flow rate of the injection water path 5 is limited to be lower than the flow rate Q3 for forming siphon by injection, so that the flushing efficiency is ensured and the flushing mode is collected in the sewage draining pipe 3 in a centralized way, and the flushing mode lasts for the time T1. After the time T1, the flushing waterway 4 is instantaneously reduced to the flow Q2, and the injection waterway 5 is instantaneously increased to the flow Q3, so that the sewage discharge pipe 3 is injected when the flow Q3 is high, the toilet bowl surface 2 is still slowly washed by the flow Q2 which is low, a siphon phenomenon is formed in the toilet bowl body 1, and the toilet bowl is efficiently flushed under the driving of the pressure difference between the toilet bowl surface 2 and the sewage discharge pipe 3. And after the time lasts for the time T2, the flow of the flushing water channel 4 is instantly increased back to the flow Q1, the flow of the spraying water channel 5 is instantly decreased to the flow Q4, and the continuous water outlet is kept for the time T3, in which the flushing is carried out again, so that the toilet bowl surface 2 is flushed for the second time and then is collected in the discharge pipe 3 in a centralized way. Until after time T3, switch the flow in water route again and can form the siphon to stop the water route and go out water after lasting different time, very big promotion the washing effect and the blowdown is cleaner.

Fig. 4 to 7 are line graphs showing the relationship between the flow rate and the time in each water passage. Wherein the line K1 is a Q-T line diagram of the flushing water passage 4, and the line K2 is a Q-T line diagram of the injection water passage 5. And, the flow rate high is represented as a preset high flow rate (e.g., a first flow rate H described below), and the flow rate low is represented as a preset low flow rate (e.g., a second flow rate L described below). The flow rates Q1, Q2 and Q5 are the flow rates of the flushing water circuit 4, and the flow rates Q2 and Q4 are the flow rates of the injection water circuit 5.

Referring to fig. 4 and 7, in a preferred embodiment, in step S2, the method further includes the following steps:

S21A: the water outlet time of the injection water path 5 and the water outlet time of the flushing water path 4 are synchronized, the injection water path 5 is in a flow increasing mode, and after the flushing water path 4 reaches the preset flow Q1, the injection water path 5 reaches the preset flow Q4 and is continuously maintained.

Specifically, in time T1, the injection waterway 5 and the flushing waterway 4 perform water outlet steps synchronously at the same time point, and the water outlet control unit 6 triggers the injection waterway 5 and the flushing waterway 4 to open water at the same time, so as to synchronously flush the interior of the toilet body 1, thereby ensuring that the waterways are sufficient and achieving a good flushing effect. And, at time T1, the flow rate of the jet water path 5 is less than the flow rate of the flush water path, and the siphon formation blowdown condition is not reached. In particular, the rate of increase of the flow rate of the injection circuit 5 is smaller than the rate of increase of the flow rate of the flushing circuit 4, and both reach the preset flow rate Q1 and the preset flow rate Q4 at the same time point and keep the flow rates to the same time.

Referring to fig. 5 and 6, in another preferred embodiment, in step S2, the method further includes the following steps:

S21B: the water outlet time of the water injection circuit 5 is delayed to a time T0 relative to the water outlet time of the flushing circuit 4, and water is discharged in an incremental flow manner at the time T0 to the time T1, so that the water injection circuit 5 reaches a flow rate Q3.

In particular, in the present embodiment, the water outlet of the injection waterway 5 is delayed, so that the water saving function is achieved, and meanwhile, preparation for siphon formation for the next stage of injection can be ensured, the water outlet efficiency is higher, and the operation is more convenient. In addition, the flow rate of the injection waterway 5 is increased from T0 to T1 in a linear increasing manner from the flow rate approaching zero to the flow rate Q3. It should be noted that in one embodiment, time T0 approaches time T1 indefinitely to momentarily increase the flow rate of injection waterway 5 to flow rate Q3.

In other embodiments, where T0 is 1/2T 1, the rate of increase K of the water injection path 5 is Q3/(T1-T0) 2Q 3/T1. Preferably, in the middle stage of time T1, the water outlet of the injection waterway 5 can be started to cooperate with the flushing waterway 4 to flush the inside of the main body 1, so that the overall flushing effect is optimized and the standards of water saving, noise reduction and the like are met.

Referring to fig. 4 to 7, specifically, a first flow rate H (flow rate high in the figure) and a second flow rate L (flow rate low in the figure) are preset. Here, the flow rates Q1 and Q3 approach the first flow rate H, and the flow rates Q4 and Q5 approach the second flow rate L. It should be noted that, when the flow rate is high, the flushing and spraying effects are more facilitated, but the limitations of large noise, waste of water resources and the like exist at the same time. And when the water storage tank is positioned at low flow, the functions of noise reduction, water saving and the like are facilitated, but the adverse factors of insufficient impulsive force, slow water storage and the like exist. The flushing control method is more suitable for occasions with high requirements on noise reduction, water saving, flushing effect and the like through switching of all flow rates and regulation and control of the flow rate.

Referring to fig. 4 and 5, the flow rate Q2 and the flow rate Q5 are defined to be substantially the same and both approach the second flow rate L. At this stage, it is ensured that the flushing waterway 4 can still provide low-flow outlet water during the initial siphon sewage disposal, so that a high pressure difference is formed on the urinal surface 2 to drive the outlet water of the flushing waterway 4 to perform deep flushing cleaning on the urinal surface 2, and the flushing is cleaner.

Referring to fig. 6 and 7, in other embodiments, the flow rate Q2 is defined to approach zero indefinitely. At this moment, when carrying out the siphon blowdown for the first time, only spout water to blow off pipe 3, take away the filth outside calandria pipe discharge closestool, operate more for simple and easy and convenient.

In one embodiment, in step S4, the method further includes the following steps:

s41: the injection waterway 5 stops water discharge before the flushing waterway 4, and the flushing waterway 4 stops water discharge at a preset time T4.

Wherein, in particular, after time T4, a liquid seal can be formed at least at the bottom of the toilet bowl. The water spraying channel 5 stops water outlet first, so that the siphon sewage draining operation stops immediately. At this time, the flushing water flow continues to discharge water at a low flow rate for a time T4 to immediately stop discharging water, so as to achieve the purpose of storing water at the sewage discharge pipe 3 and end the whole flushing control.

It should be noted that the water outlet control unit 6 preferably controls a solenoid valve (not shown) in each water path to control whether water is discharged or not. Each waterway is configured with an electromagnetic valve, and the opening of the electromagnetic valve is selected in each time period under the preset regulation and control of a control module (not shown) of the control unit. When the control module triggers the electromagnetic valve to open at a large opening degree for water outlet, the water channel is high-flow water outlet, correspondingly, when the control module triggers the electromagnetic valve to open at a small opening degree for water outlet, the water channel is low-flow water outlet. And when the electromagnetic valve discharges water at the maximum opening, the instantaneous flow of the water channel can be increased to a required flow value. When the electromagnetic valve is adjusted to discharge water with small opening, the instantaneous flow of the water channel can be reduced to a required flow value. And when the opening degree of the electromagnetic valve and the time are in a linear relation, the flow can be controlled to gradually increase or gradually decrease. In other embodiments, the valve opening degree may be controlled by other methods, which are not described herein.

The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above-mentioned embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention.
