Example two
In this embodiment, the washing machine performs a soaking process before the washing process, the soaking process generally takes up to 30min, and the soaking process is generally performed in a combination of multiple manners or multiple times in the same manner. For example, soaking is continued for 30min before the washing process, and the soaking process is generally performed according to a soaking unit a, a soaking unit B, a soaking unit C and a soaking unit C (the sum of the time for soaking the unit a, the time for soaking the unit B, the time for soaking the unit C and the time for soaking the unit C is 30min), wherein the soaking unit a is that the washing machine rotates for 2min and stops for 3min, the soaking unit B is that the washing machine rotates for 1min and stops for 4min, and the soaking unit C is that the washing machine rotates for 1min and stops for 9 min; alternatively, the soaking process may also be performed as soaking C unit + soaking C unit (the sum of the time for soaking C unit + soaking C unit is 30 min).

Wherein, the washing process is defined as the process that the washing machine continuously rotates within a set time and rubs and washes the clothes; the soaking process is defined as a process with a certain rotation-stop ratio (numerical ratio of the rotation time of the washing machine to the stop time) and combining the rotation and the non-rotation of the washing machine; in the soaking process, the rotation time of the washing machine is generally set to be less than the stop time so as to fully utilize the soaking process to perform soaking treatment on loads in the washing machine, wherein the loads can be understood as articles needing to be washed, such as clothes, trousers, towels, quilt covers and the like.
The soaking process of the washing machine is composed of various water flow intensities which are adjusted according to the rotating speed of the motor and/or the wave wheel rotation stopping ratio. During the soaking process, the washing machine can be controlled to rotate at the speed of middle-high washing speed, then the washing machine is controlled to stop rotating, so that the load subjected to washing treatment in the washing process further passes through the rotation in the soaking process, the clothes are better cleaned, the rotation process of the washing machine is stopped, the loaded clothes are soaked and stopped in the inner barrel, the residual stains on the clothes are dissolved into water, and the cleaning ratio of the clothes load is greatly improved.

Specifically, a washing program of the washing machine is started, the washing machine starts to enter a water inlet stage, the required water inlet amount is automatically judged according to the selection of a user or according to the load capacity of clothes, when the load of the clothes is more, high-water-level water amount adaptive to the load of the clothes enters a washing barrel, and after the water inlet is finished, the washing machine firstly enters a washing process within preset time, so that the upper-layer load of the inner barrel of the washing machine can be effectively turned over through relatively long washing time, and the upper-layer load and the lower-layer load of the inner barrel of the washing machine are alternately turned over for washing, so that the load in the inner barrel of the washing machine can be fully contacted with a detergent and water, and conditions are provided for the next soaking process; then, the washing machine enters a 30-minute soaking process in which the unit a is soaked (2 minutes of impeller rotation and 3 minutes off), followed by the unit B (1 minute of impeller rotation and 4 minutes off), and finally the unit C is soaked (1 minute of impeller rotation and 9 minutes off). When the load of clothes in the inner drum of the washing machine is small, the soaking process can be the combination of three soaking C units, and the proper soaking process is selected according to the difference of the loads of the clothes, so that the electric quantity can be effectively saved. Therefore, the load which is fully contacted with the detergent and the water can be further fused with the detergent and the water in the soaking process, the dirt on the load can be effectively dissolved, the function of the soaking process is effectively exerted, the cleaning ratio is improved, and the washing machine can meet the double requirements of both the cleaning ratio and the power consumption.
In this embodiment, after the washing program is started, generally, after a water inlet process of 1 minute, the washing machine automatically enters a washing process of a first set time, in this embodiment, the first set time of the washing process is set to 15 minutes, and a continuous rotation process of 15 minutes allows a load in the washing tub to be fully contacted and fused with the detergent and the water, and then enters a soaking process of a second predetermined time, the second set time of the soaking process is 30 minutes, and after a short balancing process, the next rinsing program is entered, in this embodiment, the rinsing program is spray rinsing. Finally, the washing machine enters a dehydration process.
Example eight
As shown in fig. 5, the present embodiment is different from the sixth embodiment in that: before the washing machine performs the washing process, the washing machine is controlled to perform a soaking process.
In this embodiment, the control method includes the steps of,
s201, starting a washing machine and starting a washing program;
s202, controlling the washing machine to execute a first soaking process, and executing the step S203 after the first soaking process is finished;
s203, controlling the washing machine to execute a first washing process, and executing a step S204 after the first washing process is finished;
and S204, controlling the washing machine to execute a second soaking process, and then entering the next program.
In the above technical solution, preferably, the first soaking process is a combination of the soaking unit a and the soaking unit B, the soaking unit a and the soaking unit B are performed in any order, and the second soaking process is the soaking unit C; or the first soaking process and the second soaking process are formed by overlapping the soaking unit A, the soaking unit B and the soaking unit C. Of course, other combinations are possible, and the combinations listed here are only preferred embodiments of the present invention and are not intended to limit the scope of the present invention.
In this embodiment, after the washing procedure is started, generally after a water inlet process of 1 minute, the washing machine firstly enters a first soaking process for a period of time, and then the washing machine automatically enters the washing process, so that the load in the washing tub is fully contacted and fused with the detergent and water, and then enters a second soaking process, and finally enters the next procedure. In addition, a turbidity sensor can be arranged on the washing machine, the turbidity sensor detects the cleanliness of the clothes load in real time, if the cleanliness does not reach the preset threshold, the washing is not in place, the washing is required to be continued to meet the preset threshold, and then the washing machine is controlled to circularly execute the steps S202-S204 until the preset cleanliness is met.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
