Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the basic concepts disclosed and suggested by the embodiments of the present invention, all other embodiments obtained by those skilled in the art are within the scope of protection of the present invention.

[0025] refer to Figure 1 The figure shows a schematic diagram of a washing machine detergent delivery system provided by an embodiment of the present invention. The washing machine detergent delivery system provided by this embodiment includes: n liquid storage boxes 1, each liquid storage box 1 is used to store a corresponding type of detergent, and n is greater than or equal to 3; a liquid suction delivery converter 2, the liquid suction delivery converter 2 includes an injection port 21, the injection port 21 is connected to each liquid storage box 1 through an independent connecting pipe 22, and a solenoid valve 23 is provided at one end of the connecting pipe 22 close to the injection port 21; a main control device 3, which is electrically connected to the liquid suction delivery converter 2 and the washing drum 4, and is used to determine the target liquid storage box corresponding to it according to the washing mode, and control the opening of the solenoid valve corresponding to the target liquid storage box so that the detergent in the target liquid storage box is injected into the washing drum 4 through the liquid suction delivery converter 2.

[0026] In this embodiment, the washing machine includes n liquid storage boxes 1, n is greater than or equal to 3, and the washing machine may optionally include more than 3 liquid storage boxes 1. Each liquid storage box 1 can store a type of detergent, and the detergents stored in different liquid storage boxes 1 may be the same or different. Preferably, the types of detergents stored in different liquid storage boxes 1 are different. It can be understood that the correspondence between the liquid storage box number and the type of detergent stored therein is pre-stored in the main control device 3. For example, the washing machine includes 4 liquid storage boxes a, b, c, and d, and conventional detergent is stored in liquid storage box a, clothing disinfection detergent is stored in liquid storage box b, infant detergent is stored in liquid storage box c, and wool detergent is stored in liquid storage box d. The main control device 3 records the liquid storage box number and the type of detergent stored therein.

[0027] In this embodiment, the washing machine includes a liquid suction and delivery converter 2, which includes a liquid suction function and a delivery function, that is, sucking the required detergent from the liquid storage box 1, and then delivering the sucked detergent to the washing drum 4. Obviously, the liquid suction and delivery converter 2 includes various structures that perform the liquid suction function and the delivery function, for example, the liquid suction and delivery converter 2 includes a one-belt multi-liquid suction drive module and an intelligent delivery module, for example, the one-belt multi-liquid suction drive module includes a liquid suction pump, etc., and its composition structure is not specifically described here.

[0028] The liquid suction and delivery converter 2 includes an injection port 21, which is connected to each liquid storage box 1 through an independent connecting pipeline 22, and a solenoid valve 23 is provided at one end of the connecting pipeline 22 close to the injection port 21. The optional injection port 21 is the entrance of the injection cavity, and the injection port 21 is connected to each liquid storage box 1 respectively. Specifically, the injection port 21 is connected to each liquid storage box 1 through the connecting pipeline 22 to transfer detergent, wherein the connecting pipeline 22 is provided with a solenoid valve 23. When the solenoid valve 23 is turned on, the liquid storage box 1 connected to it is connected to the injection port 21, and the detergent in the liquid storage box 1 can be sucked into the injection port 21 through the connected connecting pipeline 22; when the solenoid valve 23 is turned off, the liquid storage box 1 connected to it is disconnected from the injection port 21, and the detergent in the liquid storage box 1 cannot enter the injection port 21. Preferably, the solenoid valve 23 is disposed at the interface between the corresponding connecting pipeline 22 and the injection port 21 , which can not only realize the conduction of the connecting pipeline 22 but also seal the injection port 21 .

[0029] In this embodiment, the washing machine includes a main control device 3, which is electrically connected to the suction and delivery converter 2 and the washing drum 4. After the user operates the panel of the washing machine, the main control device 3 can determine the washing mode according to the instructions input by the user, and the washing mode can be selected to include a washing program, a type of clothing, a weight, etc. It can be understood that each washing mode corresponds to a corresponding type of detergent, and the main control device 3 can determine the target type of detergent according to the washing mode. The correspondence between the detergent and the liquid storage box 1 is known, and the main control device 3 can determine the target liquid storage box according to the target type of detergent. A solenoid valve 23 is provided on the communication pipeline 22 of each liquid storage box 1, and the main control device 3 controls to open the solenoid valve 23 corresponding to the target liquid storage box. At this time, the communication pipeline 22 between the target liquid storage box and the injection port 21 is connected, and the detergent in the target liquid storage box can be injected into the injection cavity of the suction and delivery converter 2 through the communication pipeline 22, and the suction and delivery converter 2 can deliver the target type of detergent to the washing drum 4. The process and structure of the suction and delivery converter delivering the target type of detergent to the washing drum are not specifically described here.

[0030] For example, the user operates the panel of the washing machine and selects to wash infant clothing. The main control device can determine the washing mode as infant clothing washing according to the instruction input by the user, and infant clothing washing requires infant detergent. The main control device determines that the infant detergent is stored in the liquid storage box c, and then the main control device controls to open the solenoid valve c corresponding to the liquid storage box c. At this time, the connecting pipeline between the liquid storage box c and the injection port is connected, and the infant detergent can be injected into the liquid suction and delivery converter and delivered to the washing drum 4.

[0031] In this embodiment, the detergent delivery system of the washing machine includes more than three liquid storage boxes, and a solenoid valve is provided on the connecting pipeline between each liquid storage box and the injection port. When the solenoid valve is turned on, the connecting pipeline between the corresponding liquid storage box and the injection port is turned on, and when the solenoid valve is turned off, the connecting pipeline between the corresponding liquid storage box and the injection port is turned off. Obviously, the washing machine can intelligently judge and autonomously deliver detergent according to the washing mode, which meets the user's demand for different detergent adding experience for washing clothes and reduces the tediousness of manual delivery. The detergent delivery system of the washing machine can intelligently deliver a variety of detergents, and only includes one liquid suction delivery converter, which reduces costs; it includes a one-to-many liquid suction drive delivery system, which is controlled by a program without increasing the complexity of the structure.

[0032] Optionally, the solenoid valve is an electrically controlled one-way valve. The injection port is sealed with an electrically controlled one-way valve, which improves the sealing of the injection port while realizing electrical control, thereby improving the performance and life of the washing machine. The injection port adopts an electrically controlled one-way valve to prevent water from flowing into the connecting pipeline or the liquid storage box to dilute the detergent and affect the washing effect. In addition, before each wash starts, the main control device can power on each one-way valve to allow the detergent in each connecting pipeline to flow back to the liquid storage box through pressure balance, thereby preventing the redundant detergent in the connecting pipeline from mixing in the injection chamber and affecting the washing effect.

[0033] Optionally, the main control device is also used to determine the target dosage corresponding to the washing mode, control the liquid suction and delivery converter to absorb the target dosage of detergent and then close the solenoid valve corresponding to the target liquid storage box.

[0034] In this embodiment, the user inputs a washing instruction after putting in the clothes, and the main control device determines the washing mode according to the washing instruction, wherein the washing mode may include information such as the weight and type of clothes to be washed this time, and then the main control device may determine the target dosage of detergent required for this washing according to the washing mode. For example, if the weight of the clothes to be washed this time is about 3 kg and the type of clothes is a wool sweater, the main control device may determine that the dosage of wool detergent required is 40 ml. It can be understood that the main control device is integrated with an intelligent washing program, which can realize intelligent control of the washing process, including controlling the amount of washing water, washing temperature, detergent dosage, etc.

[0035] Obviously, after the main control device determines the target dosage of detergent for this washing according to the washing mode, it will control the corresponding solenoid valve to open to inject the target type of detergent into the liquid suction and delivery converter. The main control device also monitors the dosage of detergent absorbed by the liquid suction and delivery converter in real time. When it detects that the dosage of detergent absorbed by the liquid suction and delivery converter reaches the target dosage, the main control device controls the target solenoid valve to lose power, and the target liquid storage box corresponding to the target type of detergent is disconnected from the liquid suction and delivery converter.

[0036] This enables intelligent dispensing of multiple detergents. Compared with manual dispensing, intelligent dispensing of detergent dosage can be more accurate, which can not only save detergent, but also reduce the pollution of detergent to the environment.

[0037] Optionally, the n liquid storage boxes are arranged in an array structure, or the n liquid storage boxes are arranged in a ring structure. Figure 2 As shown, the detergent delivery system includes 6 liquid storage boxes, each of which has an infusion port. The shape of the infusion port can be a disc shape or other shapes. The liquid storage boxes can be arranged in a ring structure, and the infusion ports of the liquid storage boxes are also arranged in a ring structure, which are marked as infusion ports 1, 2, 3, 4, 5, and 6 in sequence. Specifically, the user can pre-set the type of detergent for each liquid storage box, and can also modify the type of detergent for each liquid storage box according to actual needs. The liquid storage boxes and their corresponding connecting pipes and solenoid valves are numbered the same. For example, the connecting pipe corresponding to liquid storage box a is numbered as connecting pipe a, and the solenoid valve corresponding to liquid storage box a is numbered as solenoid valve a. The main control device can determine the corresponding target liquid storage box according to the target type of detergent, determine the target solenoid valve according to the number of the target liquid storage box, and control the on and off of the target solenoid valve.

[0038] In other embodiments, n liquid storage boxes may be arranged in an array structure.

[0040] In this embodiment, the main control device 3 stores the minimum liquid level parameters of each liquid storage box 1. The minimum liquid level parameters of each liquid storage box 1 may be the same. In other embodiments, the minimum liquid level parameters of at least two liquid storage boxes may be different.

[0041] The main control device 3 is electrically connected to the liquid level detector 11 in each liquid storage box 1, and is used to obtain the liquid level information of the liquid storage box collected by the liquid level detector 11 in each liquid storage box 1 in real time. The main control device 3 compares the obtained liquid storage box liquid level information with the corresponding minimum liquid level parameter. If the liquid level represented by the liquid storage box liquid level information is less than the corresponding minimum liquid level, the main control device 3 determines that the liquid storage box corresponding to the liquid storage box liquid level information is insufficient in detergent. The main control device 3 controls the alarm module 5 to issue an alarm that the detergent level of the detergent storage box is too low.

[0042] The optional alarm module includes n buzzers, one buzzer is set corresponding to one liquid storage box, when the main control device determines that liquid storage box a is insufficient in detergent, the main control device controls the buzzer corresponding to liquid storage box a in the alarm module to buzz and give an alarm. Alternatively, the optional alarm module includes n light-emitting devices, one light-emitting device is set corresponding to one liquid storage box, when the main control device determines that liquid storage box a is insufficient in detergent, the main control device controls the light-emitting device corresponding to liquid storage box a in the alarm module to give an illuminating alarm, the illuminating alarm may be flashing or always on red, and the light-emitting devices corresponding to other liquid storage boxes with sufficient detergent may not display or always on green. It is convenient for users to replenish detergent in time
