Control method for water diversion device, water diversion device and dishwasher

A control method for a water diversion device, wherein:

• the water diversion device comprises:
• a driving component on which a rotating shaft is arranged;
• a water diversion cover on which water outlets are arranged;
• a water diversion plate which is connected with the rotating shaft and provided with through holes, and which is communicated with different water outlets when the water diversion plate rotates to different state positions, so as to achieve switching of water path;
• and
• a position detection component which is arranged to send signals in a process of switching the water diversion plate between two of the state positions;
• the water outlets comprise a first circular water outlet comprising a first circle center at a center of the first circular water outlet, a second circular water outlet comprising a second circle center at a center of the second circular water outlet, and a third circular water outlet comprising a third circle center at a center of the third circular water outlet;
• the circle centers of the three water outlets are located on a first dividing circle, wherein a first imaginary radial line extends from the center of the first dividing circle to the circle center of the first circular water outlet, wherein a second imaginary radial line extends from the center of the first dividing circle to the circle center of the second circular water outlet, wherein a third imaginary radial line extends from the center of the first dividing circle to the circle center of the third circular water outlet, and wherein each pair of the first, second, and third imaginary radial lines form a 120° angle;
• the through holes comprise a first circular through hole comprising a fourth circle center at a center of the first circular through hole, a second circular through hole comprising a fifth circle center at a center of the second circular through hole, and a third circular through hole comprising a sixth circle center at a center of the third circular through hole;
• the circle centers of the first circular through hole, the second circular through hole, and the third circular through hole are located on a second dividing circle, wherein a fourth imaginary radial line extends from the center of the second dividing circle to the circle center of the first circular through hole, wherein a fifth imaginary radial line extends from the center of the second dividing circle to the circle center of the second circular through hole, and wherein a sixth imaginary radial line extends from the center of the second dividing circle to the circle center of the third circular through hole;
• an angle between the fourth imaginary radial line and the fifth imaginary radial line is 120°, and an angle between the fifth imaginary radial line and the sixth imaginary radial line is 60°;
• and
• the control method comprises:
• obtaining a target state position to be reached by the water diversion plate;
• obtaining a current state position of the water diversion plate;
• controlling the driving component to rotate the water diversion plate and counting a number of the signals;
• judging whether the water diversion plate has reached the target state position based on the target state position, the current state position, and the number of the signals;
• and
• controlling the driving component to stop rotating the water diversion plate when the water diversion plate reaches the target state position.
