Detailed Description
As shown in fig. 1, in an embodiment of the present invention, there is provided a washing machine including a drum 1, a drum driving module 2, and a mode presetting module 3. The drum 1 is used to carry laundry to be washed. The drum driving module 2 is used for controlling the drum 1 to perform a washing motion. The mode setting module 3 is used for setting washing modes of the washing machine, the mode setting module 3 sets a plurality of washing modes according to the material of clothes, and each washing mode corresponds to a drum motion mode. The drum driving module 2 controls the movement of the drum 1 according to a mode selected by a user.
The drum driving module 2 includes a rotation driving unit 21 and a movement driving unit 22, the rotation driving unit 21 is used for controlling the rotation speed and angle of the drum, and the movement driving unit 22 is used for controlling the movement direction and movement speed of the drum 1. The rotation driving unit 21 applies a centripetal force to the laundry by controlling the rotation speed of the drum 1, thereby moving the laundry together to a set angle. The moving direction of the drum 1 may be left and right, up and down, or back and forth in other directions, and the purpose of the movement of the drum 1 is to eliminate the centripetal force applied to the laundry by the inner wall of the drum 1, so that the laundry is thrown off the inner wall of the drum 1.
In some washing modes corresponding to conventional clothes provided by the embodiment of the invention, the movement mode of the drum 1 is the same as that of the conventional washing machine, namely the drum rotates clockwise, the clothes are driven to the highest point by controlling the rotation speed of the drum 1, the clothes are dropped freely, and the aim of washing the clothes is fulfilled by continuously beating the clothes.
In some washing modes set for rare clothes according to embodiments of the present invention, the drum driving module 2 controls the drum 1 to suddenly stop when rotating to a preset angle, and then controls the drum 1 to move in a set direction to throw the clothes in the drum 1 off the inner wall of the drum 1. Specifically, as shown in fig. 2, when the drum rotates clockwise to a preset rotation angle, the drum driving module 2 controls the drum 1 to suddenly stop and controls the drum to move leftward for a distance, and then controls the drum 1 to rotate counterclockwise, and when the drum 1 rotates counterclockwise to a preset rotation angle, the drum driving module 2 controls the drum 1 to suddenly stop and controls the drum to move rightward for a distance, so that the position of the drum 1 is reset. It should be noted that, by controlling the rotation speed of the drum 1, the laundry can be rotated along with the inner wall of the drum in close contact with the inner wall of the drum by the action of centrifugal force, and kept relatively still with the inner wall of the drum, after the laundry is brought to a set angle by the drum 1, the drum 1 stops suddenly and moves for a certain distance in the direction of separating from the laundry, so that the centripetal force applied to the laundry by the inner wall of the drum 1 disappears, and the laundry is separated from the inner wall of the drum 1, is thrown outwards at the speed of separating from the inner wall of the drum 1, and falls on the inner wall of the drum 1 under the action of gravity. Through testing the impact resistance of different clothes materials in advance, different drum motion modes can be set according to different clothes materials, so that the clothes made of each material can be ensured to be subjected to proper impact force when falling, and the clothes can be washed clean on the premise of not damaging the clothes.
Further, in a more refined washing mode provided in the embodiment of the present invention, the drum driving module 2 calculates a moving trajectory of the laundry according to a speed and a position of the laundry when the laundry is separated from the drum 1 and a moving distance of the drum 1, and adjusts a rotating speed and a position of the drum 1 in real time according to the moving trajectory of the laundry. It should be noted that the speed of the laundry when the laundry is disengaged from the drum 1 is the rotation speed of the drum, and the position is the rotation angle of the drum. When washing the rare clothes, the single clothes is usually washed, so that the clothes can be regarded as a mass point to estimate the motion track and the stress condition of the clothes, and the stress condition of the clothes is controlled by adjusting the rotating speed and the position of the drum 1 in real time, so that the clothes can be washed clean on the premise of not damaging the clothes.
As shown in fig. 3, in the embodiment of the present invention, the rotation driving unit 21 employs a three-loop control strategy to control the rotation angle of the drum. Specifically, the method comprises the following steps: the position of the roller is firstly given as
θr1For a set washing machine drum swing angle, when the drum reaches a set position, the adjustment position is given as
Wherein
And for the current angle of the roller 1, Pos _ dir is the rotation direction of the roller, Pos _ dir is 1 when the roller rotates forwards, and Pos _ dir is-1 when the roller rotates backwards, so that the rotation angle of the roller 1 is controlled.
Further, in an embodiment of the present invention, a control method for a washing machine is further provided, including: the drum is controlled to suddenly stop when rotating to a preset angle, and then the drum is controlled to move in a set direction so as to throw the clothes in the drum away from the inner wall of the drum. In a specific implementation manner, when the drum rotates clockwise to a preset rotation angle, the drum is controlled to suddenly stop and move a distance to the left, and then the drum is controlled to rotate counterclockwise, and when the drum rotates counterclockwise to the preset rotation angle, the drum is controlled to suddenly stop and move the same distance to the right, so that the position of the drum is reset.
In summary, the washing machine and the control method thereof of the present invention control the drum to suddenly stop when the drum rotates to a preset angle, then control the drum to move in a set direction to throw the laundry in the drum away from the inner wall of the drum, and by setting the rotation speed and angle of the drum, the falling height of the laundry can be controlled, thereby controlling the stress condition of the laundry falling onto the inner wall of the drum; the motion modes of the multiple drums can be set according to the material of the clothes, so that the stress conditions of different clothes in the washing process can be adjusted, and the optimal washing effect can be achieved under the condition of not damaging the clothes; the running track of the clothes can be calculated according to the speed and the position of the clothes when the clothes are separated from the drum and the moving distance of the drum, and the rotating speed and the position of the drum are adjusted in real time according to the running track of the clothes, so that the stress condition of the clothes in the washing process is adjusted in real time, and the washing effect is improved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
