In practical applications, the flow control system 102 may adjust the flow value of the valve 103 according to the weight of the laundry or the user's requirement.

It should be noted that fig. 1 is only an exemplary application scenario illustrating the flow control system, and is not a limitation on the shape of the washing machine, nor a limitation on the installation position of the flow control system in the washing machine.
The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 2 is a first schematic structural diagram of a flow control system provided in the present application. As shown in fig. 2, includes: the control system comprises a controller 201, a signal processor 202 and a valve 203, wherein the signal processor 202 is respectively connected with the controller 201 and the valve 203;

the valve 203 is configured to discharge the liquid having the first flow value according to the second alternating current.
Optionally, the flow control system in the present application may be disposed in a washing machine, and may also be disposed in other washing apparatuses. For example, the washing device may be a dishwasher.
Optionally, the controller may receive a flow control instruction sent by the mobile terminal or the flow control panel, where the flow control instruction includes the first flow value.
Optionally, the first flow value is determined by the controller according to a washing program selection command sent by the program control panel, or is determined by the controller according to the weight of the laundry sent by the weighing subsystem.
In one possible design, the controller may further perform a specific method of determining the target timing control signal according to the first flow rate value in the flow control command:
and determining a target timing control signal in at least one timing control signal according to the first flow value and a first corresponding relation, wherein the first corresponding relation comprises the corresponding relation between the first flow value and the target timing control signal.
Alternatively, the first correspondence relationship is a correspondence relationship stored in advance in the controller 201. For example, the first correspondence includes: the corresponding relation between the first time sequence control signal and the initial flow value A, the corresponding relation between the second time sequence control signal and the flow value B, and the corresponding relation between the third time sequence control signal and the flow value C. The first timing control signal triggers the signal processor 202 to conduct once after detecting one zero point of the first ac power, the second timing control signal triggers the signal processor 202 to conduct once after detecting two zero points of the first ac power, and the third timing control signal triggers the signal processor 202 to conduct once after detecting three zero points of the first ac power. In this application, the first ac power is ac power transmitted in the power grid 204 (shown in fig. 2) having a voltage of 220 v and a frequency of 50 hz, and the power grid 204 is used for supplying the first ac power to the controller and signal processor 202. Optionally, the controller 201 may further comprise a signal detection module, which may detect zero-crossing points of the first alternating current.
Alternatively, the flow value A, B, C may have fractional, or percent representations. For example, when the flow value A, B, C is expressed as a fraction, the initial flow value A may be 1, the flow value B may be 1/2 (i.e., 1/2 of the initial flow value A), and the flow value C may be 1/3.
In practical applications, if the first flow value is determined to be 1/2, the target timing control signal can be determined to be the second timing control signal.
In another possible design, the controller may further perform a specific method of determining the target timing control signal according to the first flow rate value in the flow control command:
determining a target zero-crossing point detection strategy in at least one zero-crossing point detection strategy according to the first flow value and a second corresponding relation, wherein the second corresponding relation comprises the corresponding relation between the first flow value and the target zero-crossing point detection strategy;
and carrying out zero crossing point detection processing on the first alternating current according to a target zero crossing point detection strategy to obtain a target time sequence control signal.
Alternatively, the second correspondence relationship is a correspondence relationship stored in the controller 201 in advance. For example, the second correspondence includes: the method comprises the steps of obtaining a flow value C, obtaining a first zero crossing point detection strategy, obtaining a second zero crossing point detection strategy, obtaining a third zero crossing point detection strategy, obtaining a corresponding relation of the first zero crossing point detection strategy and an initial flow value A, obtaining a corresponding relation of the second zero crossing point detection strategy and a flow value B, and obtaining a corresponding relation of the third zero crossing point detection strategy and a. The first zero-crossing point detection strategy detects the zero point of the first alternating current once for each half-wave, the second zero-crossing point detection strategy detects the zero point of the first alternating current once for every two half-waves, and the third zero-crossing point detection strategy detects the zero point of the first alternating current once for every three half-waves.
In practical applications, if the first flow rate value is 1/3, after the controller determines that the target zero-crossing point detection strategy is the third zero-crossing point detection strategy according to the first flow rate value 1/3, the zero-crossing point detection processing is performed on the first alternating current according to the third zero-crossing point detection strategy, so as to obtain the target timing control signal provided to the signal processor 202.
Optionally, the signal processor 202 is a thyristor switch assembly and the valve 203 is an electromagnetic water inlet valve.
Further, after receiving the target timing control signal, the signal processor 202 performs an on-off cycle operation according to the target timing control signal. During the on-off cycle, the signal processor 202 may perform a waveform shaping process on the first ac power to obtain a second ac power, and provide the second ac power to the valve 203. The valve 203 discharges the liquid with the first flow value according to the second alternating current. Alternatively, the liquid may be water, or may be washing water in which washing water is dissolved.
