Description
Technical Field
The invention belongs to the field of washing machines, and particularly relates to a control method of a washing machine and the washing machine.
Background
The washing machine is a household appliance which is widely used in daily life of people, helps people get rid of the trouble of washing clothes, and brings great convenience to people. Most of the washing machines control the water inflow of the washing machine according to the detected water level information.
However, the current method for detecting water level information in a washing machine mainly includes: a water inlet valve with an automatic putting function is arranged on the washing machine, and the water inlet valve calculates and obtains the water inflow according to the water outlet time so as to obtain the water level information in the washing machine. However, in this solution, when the inflow water pressure is abnormal, the calculated and obtained inflow amount is inaccurate, which results in inaccurate obtained water level information.
Therefore, a water level detecting apparatus for a washing machine has appeared on the market, the washing machine including a washing tub that can independently contain washing water, and further including: the accommodating cavity extends from the bottom of the washing barrel to the direction of the barrel opening and is communicated with the washing barrel; the floater is internally provided with a magnet, is arranged in the accommodating cavity and can float along with the water level; the magnetic induction device is arranged outside the washing barrel and used for inducting and detecting the height of the floater; and the display device is electrically/communicatively connected with the magnetic induction device and is used for displaying the water level in the washing barrel corresponding to the height of the floater. This scheme can real-time induction detect the height of float through magnetic induction device to show through display device.
However, in the above technical solution, along with the rotation of the washing tub or the agitation of the pulsator, the water level in the accommodating chamber may fluctuate up and down, the float may fluctuate along with the fluctuation of the water level in the accommodating chamber, and the water level detected by the float in the fluctuation condition is inaccurate.
When the fluctuation of the floater is at a wave crest, the detected water level value is higher than the actual water level value, so that the subsequent water inflow of the washing machine is less, and the cleaning effect of clothes is poor;
when the fluctuation of the floater is at the wave valley, the detected water level value is lower than the actual water level value, so that the subsequent water inflow of the washing machine is excessive, and the waste of water resources is caused.
In addition, hold the chamber setting on the washing barrel, in case the washing leads to the position of rotating to keeping away from magnetic induction device, then float and magnetic induction device's distance becomes far away, leads to the unable position of sensing the float of magnetic induction device, and then can't detect the water level.
