Description

Multi-flush mode toilet flushing system

[ field of technology ]

The utility model relates to the technical field of toilet flushing systems, in particular to the technical field of multi-flushing mode toilet flushing systems.

[ background Art ]

The toilet bowl, commonly called toilet bowl, is characterized by taking the sitting form by human body when in use, and is divided into two types of direct flushing type and siphon type according to flushing mode. The toilet flush fill valve typically has two outlets, one of which connects to the bowl wall flush side (RIM side) and the other to the siphon flush side (JET side). The RIM side tube outlet is typically located below the toilet inner seat near the seat, while the JET side tube outlet is located lower, typically at the toilet bowl water reservoir. The toilet bowl is generally flushed by brushing the ring-shaped water outlet on the RIM side, flushing the water outlet on the JET side, flushing the ring-shaped water outlet on the RIM side and filling the water seal.

As shown in fig. 1, the conventional toilet flushing system generally includes a mechanical water replenishment valve b, a water tank c, a water pump d and an electric directional valve e connected in series between a water source a and a toilet. The water tank c is filled with water by adopting a standard floating ball water piece, and the electric reversing valve e realizes water outlet switching of the RIM side and the JET side of the closestool in an electric driving mode. Although the design has the advantage of relatively simple system layout, the flushing of the closestool can be realized only when the water pump d is started, so that once the power is cut off or the water pump d fails, the flushing cannot be realized, and the trouble is easily brought to users. Therefore, some manufacturers choose to add a battery to supply power to the water pump d when the power is cut off, but because the driving power of the water pump d is very high, the water pump d must be equipped with a special large capacitor or a large-capacity battery to drive, so that the power cut flushing cost is high, the power cut flushing frequency is limited, the potential safety hazard is involved, and the emergency flushing when the water pump d fails still can not be realized.

Referring to fig. 2, for the above technical problem, the simplest solution is to connect two flushing valves (i.e. the first flushing valve f and the second flushing valve g) in parallel. However, this design method increases many pipeline connections, occupies a larger space, has a higher layout difficulty, and still has a higher setting cost.

Wherein, the valve 2 can be controlled by an electric control coil, the switcher 5 can be controlled by a motor, and the valve 2 and the switcher 5 can be simultaneously controlled by manual operation.

The working procedure of this embodiment is:

1) Mode one (water pump flush mode):

first, the water pump 4 is electrically activated, so that water in the water tank 3 flows along the working waterway (i.e., thick line portion of fig. 5) and brushes the ring from the RIM side. Next, the switch 5 is controlled by the motor to switch the water outlet direction from the RIM side to the JET side, so that the water in the water tank 3 flows along the working waterway (i.e., the thick line portion of fig. 6) and the JET undershoot of the toilet is completed. Finally, the water outlet direction is switched from the JET side to the RIM side by controlling the switcher 5 with the motor, thereby replenishing the water seal through the RIM side.

2) Mode two (tap water electric flushing mode):

first, the valve 2 is actuated by the electric control coil, so that tap water flows along the working waterway (i.e., thick line portion of fig. 7) and brushes the coil from the RIM side. Next, the switch 5 is controlled by the motor to switch the water outlet direction from the RIM side to the JET side, thereby flowing tap water along the working waterway (i.e., the thick line portion of fig. 8) and completing the JET bottom flushing of the toilet. Finally, the water outlet direction is switched from the JET side to the RIM side by controlling the switcher 5 with the motor, thereby replenishing the water seal through the RIM side.
