[0047] Embodiment 1

[0048] As shown in Figures 1 to 4 The present embodiment provides a door for a drum washing machine, the drum washing machine comprising a box body and a drum, the drum being rotatably arranged in the box body; a front panel of the box body is provided with a taking and placing opening at a position corresponding to a drum opening of the drum, the taking and placing opening being used for taking and placing laundry; the door comprises:

[0049] a door body being openably and closably arranged at the drum opening of the drum, the door body being openable or closable to the taking and placing opening; the door body comprises an observation window 13 and a door frame, the observation window 13 being arranged on the door frame; an observation window cavity 133 is formed in the interior of the observation window 13, and a liquid dispensing opening 134 is formed in the side wall of the observation window 13; the door frame is provided with a liquid storage cavity 141, the liquid storage cavity 141 being used for storing laundry treatment agents, the laundry treatment agents comprising at least one of a detergent, a softener, a bleaching agent and a disinfectant; the liquid storage cavity 141 is located outside the observation window 13; specifically, one side of the door body is rotatably arranged on the box body through a rotating shaft 34;

[0050] The liquid injection assembly 2 is arranged in the observation window cavity 133 and forms a liquid injection flow path that communicates the liquid storage cavity 141 and the liquid injection port 134, and the liquid injection flow path is used to inject the laundry treatment agent in the liquid storage cavity 141 into the drum through the liquid injection port 134. The liquid in the drum cannot enter the observation window cavity 133, thereby avoiding the problem that the liquid in the drum damages the liquid injection assembly 2.

[0051] The positions of the liquid storage cavity 141 and the observation window 13 affect the overall structure and space occupation of the door and the arrangement of the liquid injection assembly 2, which will be further described below. The liquid storage cavity 141 and the observation window 13 are arranged on the side of the door frame close to the drum, and the liquid storage cavity 141 is located below the observation window 13. The liquid storage cavity 141 is formed with an adding port 142 and a liquid discharge port. The adding port 142 is used to add the laundry treatment agent into the liquid storage cavity 141, and the liquid discharge port is used to discharge the laundry treatment agent in the liquid storage cavity 141. The door frame is formed with a door frame hole and a pipe passing hole 112, and the door frame hole and the observation window cavity 133 are communicated.

[0052] Specifically, the adding port 142 is arranged away from the rotating shaft 34 of the door body and located at the top of the liquid storage cavity 141. The position is appropriate and convenient for adding the laundry treatment agent. When the door body is opened, the user can add the laundry treatment agent into the liquid storage cavity 141 through the adding port 142.

[0053] The liquid injection assembly 2 is arranged in the observation window cavity 133 through the door frame hole and includes a liquid suction pipe 21, a liquid suction pump 22 and a liquid injection pipe 23. The liquid suction pipe 21 is arranged in the pipe passing hole 112, and the liquid discharge port, the liquid suction pipe 21, the liquid suction pump 22, the liquid injection pipe 23 and the liquid injection port 134 are sequentially communicated to form the liquid injection flow path.

[0054] When the drum washing machine runs the washing program, the liquid suction pump 22 operates, and the laundry treatment agent in the liquid storage cavity 141 enters the drum through the liquid injection flow path, thereby realizing the intelligent injection of the laundry treatment agent.

[0055] Specifically, the liquid injection port 134 can be provided in plurality, and the plurality of liquid injection ports 134 are arranged at intervals on the side wall of the observation window 13 and are arranged at intervals in at least one of the left-right direction and the up-down direction. Each liquid injection port and the liquid suction pump 22 are communicated through the corresponding liquid injection pipe 23. When the liquid suction pump 22 operates, the laundry treatment agent can be discharged into the drum through the corresponding liquid injection pipe 23 and the liquid injection port. Different liquid injection ports can discharge the laundry treatment agent to different areas of the drum, so that the laundry treatment agent is more evenly injected into the drum and fully contacts with the laundry in the drum.

[0056] Preferably, the liquid injection port corresponding to the position of the laundry distribution in the drum is used to inject the laundry treatment agent into the drum, wherein the laundry distribution in the drum includes the distribution position of the laundry and the volume of the laundry; ① the greater the distance between the distribution position of the laundry and the door body, the higher the position of the liquid injection port used to inject the laundry treatment agent into the drum, the farther the injection distance of the laundry treatment agent, and more laundry treatment agent contacts the laundry in the drum; for example, when the distribution position of the laundry is close to the door body, the liquid injection port at a high position is used to inject the laundry treatment agent into the drum; when the distribution position of the laundry is far away from the door body, the liquid injection port at a low position is used to inject the laundry treatment agent into the drum; ② the greater the distance between the distribution position of the laundry and the door body, the greater the injection speed of the laundry treatment agent by the liquid injection port, the farther the injection distance of the laundry treatment agent, and more laundry treatment agent contacts the laundry in the drum; ③ the greater the volume of the laundry, the greater the flow of the laundry treatment agent injected by the liquid injection port or the longer the injection time.

[0057] When the door body is opened or closed, the laundry treatment agent in the liquid storage cavity 141 shakes and is easily attached to the inner wall surface of the liquid storage cavity 141, which causes inaccurate observation or detection of the liquid level of the laundry treatment agent. In this embodiment, the inner wall surface of the liquid storage cavity 141 is provided with a flow guide rib 143, which is used to guide the laundry treatment agent on the inner wall surface of the liquid storage cavity 141 to the bottom of the liquid storage cavity 141, thereby avoiding the problem of inaccurate observation or detection of the liquid level caused by the residual laundry treatment agent on the inner wall surface of the liquid storage cavity 141.

[0058] Specifically, the flow guide rib 143 extends from top to bottom, which can quickly guide the laundry treatment agent attached to the inner wall surface of the liquid storage cavity 141 to the bottom of the liquid storage cavity 141.

[0059] In some embodiments, a liquid-repellent material can also be coated on the inner wall surface of the liquid storage cavity 141, which has a repelling effect on the laundry treatment agent, reduces the adhesion of the laundry treatment agent, and makes the laundry treatment agent quickly flow to the bottom of the liquid storage cavity 141.

[0060] Alternatively, the inner wall surface of the liquid storage cavity 141 is provided with a flow blocking rib, which is used to reduce the shaking amplitude of the laundry treatment agent in the liquid storage cavity 141 when the door body is opened or closed. Specifically, the flow blocking rib extends in the horizontal direction.

[0061] During the operation of the drum washing machine, the door body will vibrate, which will cause the connection between the liquid injection pipe 23 and the liquid injection port 134 to be loose, resulting in that the laundry treatment agent cannot smoothly enter the drum through the liquid injection pipe 23 and the liquid injection port 134. In this embodiment, the liquid injection assembly 2 further includes a pipe joint, and the pipe joint includes a joint main body 241; the joint main body 241 is arranged at the liquid injection port 134, and a sealing member 25 is arranged between the joint main body 241 and the liquid injection port 134, thereby avoiding the liquid in the drum from flowing back into the observation window cavity 133.
