The electromagnetic valve 23 is connected, so that the connected liquid storage box 1 is communicated with the injection port 21, at the moment, the detergent in the liquid storage box 1 can be sucked into the injection port 21 through the connected communication pipeline 22, and the electromagnetic valve 23 is disconnected, so that the connected liquid storage box 1 is disconnected from the injection port 21, and at the moment, the detergent in the liquid storage box 1 cannot enter the injection port 21. The electromagnetic valve 23 is preferably provided at the interface between the communication line 22 and the inlet 21, which corresponds to the electromagnetic valve, so that the communication line 22 is connected or disconnected, and the inlet 21 is sealed.
In this embodiment, the washing machine includes a main control device 3, and the main control device 3 is electrically connected to the liquid-absorbing delivery converter 2 and the washing drum 4, respectively. After the user operates the panel of the washing machine, the main control device 3 may determine a washing mode according to a command input by the user, and the washing mode may be selected to include a washing program, a laundry kind, a weight, and the like. It will be understood that each washing mode corresponds to its corresponding detergent type, and the main control device 3 can determine the target detergent type according to the washing mode, and knowing the correspondence between the detergent and the liquid storage box 1, the main control device 3 can determine the target liquid storage box according to the target detergent type. The electromagnetic valve 23 is arranged on the communication pipeline 22 of each liquid storage box 1, the main control device 3 controls and opens the electromagnetic valve 23 corresponding to the target liquid storage box, at the moment, the communication pipeline 22 between the target liquid storage box and the injection opening 21 is conducted, the detergent in the target liquid storage box can be injected into the injection cavity of the liquid absorption injection converter 2 through the communication pipeline 22, and the liquid absorption injection converter 2 can inject the target type detergent into the washing cylinder 4. The process and structure of the liquid-suction dispensing switch to dispense the target type of detergent into the wash tub is not described in detail herein.
For example, the user operates the panel of the washing machine to select to wash the infant clothes, and the main control device can determine that the washing mode is infant clothes washing according to the instruction input by the user, and the infant clothes washing needs infant detergents. The main control device determines that the infant detergent is stored in the liquid storage box c, the main control device controls and opens the electromagnetic valve c corresponding to the liquid storage box c, at the moment, a communication pipeline between the liquid storage box c and the injection opening is conducted, and the infant detergent can be injected into the liquid suction and delivery converter and delivered to the washing cylinder 4.
In this embodiment, the washing machine detergent delivery system includes more than 3 liquid storage boxes, and the communication pipeline between each liquid storage box and the filling port is provided with the solenoid valve, and the solenoid valve switches on the communication pipeline between the corresponding liquid storage box and the filling port, and the solenoid valve switches off the communication pipeline between the corresponding liquid storage box and the filling port.

In this embodiment, after a user puts in clothes, a washing instruction is input, and the main control device determines a washing mode according to the washing instruction, where the washing mode may include information such as a weight of the clothes to be washed and a type of the clothes, and then the main control device may determine a target dosage of the detergent required for the washing according to the washing mode. For example, the laundry weight of this time is about 3Kg, and the laundry type is a sweater, the main control device can determine that the required dosage of the wool detergent is 40ml, and it can be understood that the main control device is integrated with an intelligent washing program, so that the intelligent control of the washing process can be realized, including control of the washing water consumption, the washing temperature, the detergent dosage and the like.
Obviously, after the main control device determines the target dosage of the washing agent washed at this time according to the washing mode, the corresponding electromagnetic valve is controlled to be opened so as to inject the washing agent of the target type into the liquid absorbing and throwing converter. The main control device also monitors the detergent amount sucked by the liquid suction and delivery converter in real time, and when the detergent amount sucked by the liquid suction and delivery converter is detected to reach the target dosage, the main control device controls the target electromagnetic valve to lose power, so that the communication between the target liquid storage box corresponding to the target type of detergent and the liquid suction and delivery converter is disconnected.
Therefore, intelligent delivery of various detergents can be realized. Compared with manual delivery, the intelligent detergent delivery can be more accurate, not only can the detergent be saved, but also the pollution of the detergent to the environment can be reduced.
