Flush toilet

A flush toilet comprising:

• a toilet stool unit that defines a bowl space;
• a toilet seat that is pivotably disposed on said toilet stool unit;
• a toilet cover that is pivotably mounted to said toilet stool unit, and that is movable relative to said toilet stool unit between a covering position to close said bowl space and an uncovering position to open said bowl space;
• a water tank unit that includes
• an outer tank body,
• an inner tank body disposed in said outer tank body and defining a water storage space therein, and
• a cover member disposed detachably on a top portion of said outer tank body, and having a front side that is formed with a mounting slot extending therethrough;
• a pipe unit that includes
• a flow-out pipe in fluid communication with said bowl space and disposed upstream of said bowl space,
• a first flow-in pipe disposed downstream of said water storage space and in fluid communication with said water storage space, and
• a second flow-in pipe disposed downstream of said water storage space and in fluid communication with said flow-out pipe;
• an electric switching valve that is connected in series between said flow-out pipe and said first flow-in pipe, and that is switchable between a blocked state and a communicated state, fluid communication between said flow-out pipe and said first flow-in pipe being blocked when said electric switching valve is in the blocked state, said flow-out pipe and said first flow-in pipe being in fluid communication with each other when said electric switching valve is in the communicated state;
• a flush valve that is disposed upstream of said second flow-in pipe and that is switchable between a closed state and an open state, fluid communication between said second flow-in pipe and said water storage space being blocked when said flush valve is in the closed state, said second flow-in pipe and said water storage space being in fluid communication with each other when said flush valve is in the open state;
• a manual actuating unit that is coupled to said flush valve for actuating movement of said flush valve from the closed state to the open state;
• a driver that is mounted to said toilet stool unit, and that is coupled to said toilet cover for driving said toilet cover to move between the covering position and the uncovering position;
• and
• a sensor control unit that includes
• at least one sensor disposed in said mounting slot, and
• a controller signally connected to said at least one sensor, and signally connected to said electric switching valve and said driver, said sensor control unit being disposed for controlling switching of said electric switching valve between the blocked state and the communicated state, and for controlling said driver to drive said toilet cover to move between the covering position and the uncovering position.
