detail

Hereinafter, the embodiments of the present application will be described in detail with reference to the accompanying drawings. It should be noted that, the embodiments in the present application and the features in the embodiments may be arbitrarily combined with each other if there is no conflict.

As shown in FIGS. 1-4 , an embodiment of the present application provides a flushing system for a toilet, including a flushing control device. The flushing control device includes a housing 1 , an anti-siphon valve 2 and a jet switch valve 3 . The housing 1 has an inlet The water outlet 103, the scrubbing water outlet 104 and the jetting water outlet 105, the anti-siphon valve 2 is arranged at the water inlet 103 and controls the opening and closing of the water inlet 103, and the jet switch valve 3 is arranged at the jetting water outlet 105 and controls the opening and closing of the jetting water outlet 105. Open and close, the scrubbing water outlet 104 is in a normally open state.

During the flushing process of the siphonic toilet, the siphon effect will occur when the water flushed into the toilet passes through the highest point of the siphon pipe. Under the siphon effect, the sewage can be discharged from the toilet from the sewage outlet. The inventor of the present application has keenly found in practice that if the siphon action can be made earlier and completed faster during the flushing process, the time of the entire flushing process can be shortened, and the time from the start of the flushing process to the siphon action can be reduced.
