Control method and controlling device of front-loader washing machine and front-loader washing machine

Abstract

The invention discloses a control method and controlling device of front-loader washing machine and a front-loader washing machine. The method comprises starting a drain valve of a front-loader washing machine at first set intervals to drain water from a washing drum of the front-loader washing machine, when a spinning instruction is received; continuously and repeatedly controlling the rotational speed of a motor of the front-loader washing machine change into a second rotational speed from a first rotational speed and then change into the first rotational speed from the second rotational speed, when that the water level in the washing drum reaches up to a first preset height is detected, and controlling the drain valve to drain water according to a rotational speed of the motor, so as to quickly discharge foam in the washing drum. The control method is simple in control mode with no additional devices, the cost is reduced, the effect that foam can be normally discharged is distinctly improved, the problem that spilled foam influences a washing machine can be solved, and the availability of the washing machine can be raised.

Description

technical field [0001] The invention relates to the technical field of living appliances, in particular to a control method and a control device for a drum washing machine and a drum washing machine with the control device. Background technique [0002] At present, during the use of the drum washing machine on the market, if the user accidentally puts in too much detergent, a large amount of foam will be generated in the washing tub during the washing process, and the large amount of foam generated will penetrate into the inside of the clothes fabric, so that the drum When the washing machine is dehydrating, the foam in the clothes will be squeezed out with the high-speed rotation of the inner tub, making the foam fill the entire washing tub, which may cause foam to spray out from the detergent box, which will affect the use of the washing machine and even damage the washing machine. Contents of the invention [0003] The object of the present invention is to solve one of ...
