Closestool flushing method

Abstract

The invention discloses a closestool flushing method. The method comprises the following steps that 1, a flushing signal generated due to starting of a user is received through a control unit; 2, the control unit starts a valve unit, and a cleaning pipeline of a closestool is kept in a water-running state for T1 seconds; 3, after the cleaning pipeline is kept in the water-running state for T1 seconds, the control unit controls the valve unit, so that the valve unit stops water supply to the cleaning pipeline, and meanwhile a jetting pipeline of the closestool is kept in the water-running state for T2 seconds; 4, after the jetting pipeline is kept in the water-running state for T2 seconds, the control unit controls the valve unit, so that the valve unit stops water supply to the jetting pipeline, and meanwhile the cleaning pipeline is kept in the water-running state once more for T3 seconds; 5, after the cleaning pipeline is kept in the water-running state once more for T3 seconds, the control unit switches off the valve unit to end a flushing control program. By the adoption of the flushing steps, the flushing procedure is operated in a phased mode, the good siphon effect can be generated, water can be saved to a certain extent, in particular, the flushing performance at the time of low pressure is improved, and the method is simple, feasible and obvious in effect.

Description

Technical field [0001] The invention relates to a toilet flushing method in the field of sanitary ware. Background technique [0002] Most of the existing siphon toilets include a washing water outlet at the top of the toilet bowl and a spray water outlet at the bottom of the toilet bowl. The water flowing from the washing water outlet is used to clean the inner wall of the toilet. The water flowing out from the jetting hole is used to spray the bottom of the toilet bowl to generate siphon so as to transport the dirt on the inner wall of the toilet bowl and the bottom of the toilet to the sewage bend. When flushing, water is generally allowed to flow out from the flushing water outlet hole and the jetting water outlet at the same time to simultaneously wash the inner wall of the toilet bowl and spray the bottom of the toilet bowl to generate siphon until the flushing is completed. [0003] Since water flows out from the washing outlet and the jet outlet at the same time, on the on...

Problems solved by technology

[0003] Since the water flows out from the cleaning outlet hole and the spray outlet hole at the same time, on the one hand, the amount of water allocated to the cleaning outlet hole and the injection outlet hole cannot reach the best effect. The amount of water flowing out of the water outlet hole cannot be kept relatively stable, and may be more or less, resulting in an unstable cleaning effect on the inner wall of the toilet bowl or an unstable jet flushing effect on the bottom of the toilet bowl; The flushing water flowing out of the water outlet hole must first wash the inner wall of the toilet bowl before flowing into the water seal at the bottom of the toilet bowl. Simultaneously supplying water to the cleaning water outlet hole and the jet water outlet hole will cause the washing water to not flow to the toilet bowl In the water seal at the bottom of the urinal, the spray hole has already started to spray flushing water to form a siphon, so that the part of the flushing water flowing out of the clean water hole is not fully utilized to participate in the siphon, which is not conducive to promoting the formation of the siphon; on the other hand, At the same time, the water supply to the cleaning water outlet hole and the spray water outlet hole will cause the water supply pressure to be dispersed, so that the injection pressure and flow rate at the injection water outlet hole at the bottom of the toilet bowl are small, making the jet siphon effect poor and wasting water resources. At the same time, The spray pressure and flow at the flushing outlet hole on the top of the toilet bowl are also small, resulting in poor scrubbing effect on the inner wall of the toilet bowl, especially when the water supply pressure is low, the flushing performance is even worse
