The water inlet control method as claimed in any one of claims 7 to 9, wherein the washing machine is provided with a visual signal projecting device 1, the visual signal projecting device 1 projects a visual signal in a height direction inside the inner tub 4 for a user to select a water inlet height; comprises the following steps:
s1, the washing machine is started, and the user selects to control water inflow automatically;
s2, the user adjusts the visible signal projecting device (1) to project the visible signal to the corresponding part in the inner barrel (4) and selects the water inlet height;
s3, the visible signal projection device (1) transmits wave signals to the water inlet height part, receives the reflected wave signals, converts the reflected wave signals into electric signals and transmits the electric signals to the washing machine, and the corresponding water inlet level height is obtained and water inlet is controlled;
s4, when the water inlet height in the barrel reaches the water inlet height projected by the visual signal, the water inlet is finished;
preferably, a water inlet level memory function is set, and when a user selects to control the water inlet and the memory function automatically, the washing machine directly controls water inlet according to the water inlet level of the historical record.
