Abstract

The invention provides a control method for a reciprocating piston type washing machine. The control method for the reciprocating piston type washing machine comprises the following steps that step a, a motor rotates to drive a piston to run; step b, in the running process of the piston, a detecting unit detects whether the piston reaches an extreme position of a running stroke or not; step c, when the detecting unit detects that the piston reaches the extreme position of the running stroke, a control unit controls the motor to stop rotating and change the rotating direction, the steps a-c are repeated, and when the detecting unit detects that the piston does not reach the extreme position of the running stroke, the motor continues an original moving state, the steps b-c are repeated. By means of the control method for the reciprocating piston type washing machine and the washing machine, the technical problem that the piston stroke of a piston type washing machine can not be well controlled is solved, it is guaranteed that the strength of the extrusion force exerted on clothes during washing every time is accordant, the machine is prevented from being damaged, the wear of the clothes is relieved, the better kneading effect is achieved, and the washing effect is effectively improved.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a control method for a reciprocating piston washing machine and the washing machine. Background technique [0002] The reciprocating piston washing machine is a washing machine that uses a reciprocating piston to intermittently squeeze and rub the clothes to achieve the purpose of washing. In order to achieve an ideal washing effect, it is necessary to control the piston to exert an appropriate squeezing force on the clothes. Since the amount of clothes washed each time is different, the space occupied by the clothes in the washing machine is also different. This requires the washing machine to automatically control the stroke of the piston according to the amount of clothes. The stroke needs to be larger, and when there are more clothes, the piston stroke needs to be smaller. [0003] However, the existing announced reciprocating piston washing machine cannot or cannot well rea...
