when the lifting rib (3) rotates to a position half of the height of the inner barrel (1) along with the inner barrel (1), infrared rays emitted by the infrared emitter (4) can pass through the two lifting ribs (3) which are oppositely arranged to reach the infrared receiver (6); when there is the clothing on promotion muscle (3), the clothing can shelter from the infrared ray that infrared emitter (4) sent, make infrared receiver (6) can not receive the signal, need control not reduce the water level this moment, when there is not the clothing on promotion muscle (3), infrared receiver (6) can receive the infrared ray that infrared emitter (4) sent, need control to reduce the water level this moment.
5. A washing machine according to any one of claims 1-2, characterized in that:
the device also comprises a water inlet valve (7) and a water discharge pump (9); and/or the lifting rib (3) is made of transparent material.
6. A control method of a washing machine according to any one of claims 1 to 5, characterized in that: the method comprises the following steps:
a detection step, which is used for detecting the positions of the two lifting ribs (3) which are arranged in a 180-degree circumference opposite manner and detecting whether an infrared signal is received or not through the infrared receiver;
a judging step, which is used for judging whether the inner cylinder is positioned at an initial position, wherein the initial position is a position at which the two lifting ribs (3) which are oppositely arranged in a 180-degree circumference are positioned at a half height of the inner cylinder (1);
and a control step, which is used for controlling the inner drum (1) to rotate 180 degrees and detect the infrared signal again when the inner drum is positioned at the initial position and the infrared receiver receives the infrared signal, and controlling the washing machine to start washing until the infrared receiver does not detect the infrared signal.
7. The control method of a washing machine according to claim 6, wherein:
and the control step is also used for controlling a drain valve of the washing machine to discharge quantitative water M2 when the nth time receives the infrared signal, controlling the inner drum (1) to rotate 180 degrees and detecting the infrared signal again, wherein n is more than or equal to 1.
8. The control method of a washing machine according to claim 7, wherein:
setting the initial water inflow of the inner barrel (1) to be M1, wherein the detection step is also used for detecting the residual water in the inner barrel, and the control step is also used for controlling the residual water to be: when M1-M × M2> M3, controlling the inner cylinder (1) to rotate 180 DEG, and detecting the infrared signal again, wherein M3 is the lowest allowable water amount in the inner cylinder; when the residual water amount is: and when M1-M M2 is not more than M3, controlling the washing machine to start washing, wherein M is more than 0 and M cycles.
9. The control method of a washing machine according to claim 8, wherein:
the control step is also used for controlling the initial water inflow M1 of the water inlet valve of the washing machine to be a horizontal plane at a position not exceeding half of the height of the inner drum (1).
10. The control method of a washing machine according to claim 9, wherein:
the detection step is also used for detecting the weight of the clothes to be washed;
the controlling step is also used for controlling the initial water inflow M1 according to the weight of the clothes.
