[0045] In the existing drum washing machine, the clothes treatment agent storage and delivery device is located at the upper corner of the washing machine, which makes it difficult for the user to check the remaining amount of clothes treatment agent in the storage box and is not conducive to timely adding clothes treatment agent; and the internal space of the protruding part of the observation window is not utilized, which causes a certain amount of space waste;

[0046] The present invention creatively provides a door for a drum washing machine, wherein the door body comprises an observation window and a door frame, wherein an observation window cavity is formed inside the observation window, and the door frame is provided with a liquid storage cavity, which is located outside the observation window; a liquid dosing assembly is arranged in the observation window cavity and forms a liquid dosing flow path connecting the liquid storage cavity and a liquid dosing port, and clothing treatment agent in the liquid storage cavity can enter the drum through the liquid dosing flow path; the liquid storage cavity and the liquid dosing assembly are integrated on the door body, thereby reducing the number of holes in the washing machine body, making full use of the internal space of the observation window, and saving the space occupied by the liquid storage cavity and the liquid dosing assembly; making the washing machine structure more compact, and realizing the intelligence and lightweight of the washing machine.

[0047] Example 1

[0048] like Figures 1 to 4 As shown, this embodiment provides a door for a drum washing machine, which includes a housing and a drum, wherein the drum is rotatably arranged in the housing; a front panel of the housing is provided with a take-in and put-out opening at a position corresponding to the drum opening of the drum, and the take-in and put-out opening is used for taking clothes in and out; the door includes:

[0049] The door body is openably arranged at the mouth of the drum, and the door body can open or close the access opening; the door body includes an observation window 13 and a door frame, and the observation window 13 is arranged on the door frame; an observation window cavity 133 is formed inside the observation window 13, and a liquid injection port 134 is formed on the side wall of the observation window 13; the door frame is provided with a liquid storage cavity 141, and the liquid storage cavity 141 is used to store clothing treatment agents, and the clothing treatment agents include at least one of detergents, softeners, bleaching agents, and disinfectants; 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 dosing component 2 is arranged in the observation window cavity 133 and forms a liquid dosing path connecting the liquid storage cavity 141 and the liquid dosing port 134. The liquid dosing path is used to discharge the clothing treatment agent in the liquid storage cavity 141 into the drum through the liquid dosing 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 dosing component 2.

[0051] The positions of the liquid storage chamber 141 and the observation window 13 affect not only the overall structure and occupied space of the door, but also the arrangement of the liquid dosing assembly 2, which will be further described below; the liquid storage chamber 141 and the observation window 13 are both arranged on the side of the door frame close to the drum, and the liquid storage chamber 141 is located below the observation window 13; the liquid storage chamber 141 is formed with an addition port 142 and a liquid discharge port, the addition port 142 is used to add clothing treatment agent into the liquid storage chamber 141, and the liquid discharge port is used to discharge the clothing treatment agent in the liquid storage chamber 141; the door frame is formed with a door frame hole and a pipe hole 112, and the door frame hole is connected to the observation window chamber 133;

[0052] Specifically, the adding port 142 is arranged away from the rotating shaft 34 of the door body and is located at the top of the liquid storage chamber 141; the location is suitable for conveniently adding clothing treatment agent; when the door body is opened, the user can add clothing treatment agent into the liquid storage chamber 141 through the adding port 142;

[0053] The liquid dosing assembly 2 is arranged in the observation window cavity 133 through the door frame hole and includes a liquid extraction pipe 21, a liquid extraction pump 22 and a liquid dosing pipe 23; the liquid extraction pipe 21 is passed through the pipe hole 112, and the liquid discharge port, the liquid extraction pipe 21, the liquid extraction pump 22, the liquid dosing pipe 23 and the liquid dosing port 134 are sequentially connected to form a liquid dosing flow path;

[0054] When the drum washing machine runs a washing program, the liquid pump 22 is running, and the clothes treatment agent in the liquid storage chamber 141 enters the drum through the liquid feeding flow path, realizing intelligent feeding of the clothes treatment agent;

[0055] Specifically, a plurality of liquid injection ports 134 may be provided, and the plurality of liquid injection ports 134 are spaced apart on the side wall of the observation window 13, and the plurality of liquid injection ports 134 are spaced apart in at least one of the left-right direction and the up-down direction; each liquid injection port is connected to the liquid pump 22 through a corresponding liquid injection pipe 23, and when the liquid pump 22 is in operation, the clothing treatment agent may be discharged into the drum through the corresponding liquid injection pipe 23 and the liquid injection port, and different liquid injection ports may discharge the clothing treatment agent into different areas of the drum, so that the clothing treatment agent is more evenly injected into the drum and fully contacts the clothing in the drum;

[0056] Preferably, the liquid injection port at the corresponding position can be used to inject clothing treatment agent into the drum according to the distribution of the clothing in the drum; wherein the distribution of the clothing in the drum includes the distribution position of the clothing and the volume of the clothing; ① the larger the distance between the distribution position of the clothing and the door body, the higher the position of the liquid injection port for injecting the clothing treatment agent into the drum, so that the injection distance of the clothing treatment agent is longer and more clothing treatment agent contacts the clothing in the drum; for example, when the distribution position of the clothing is close to the door body, the liquid injection port at a higher position is used to inject clothing treatment agent into the drum; when the distribution position of the clothing is far from the door body, the liquid injection port at a lower position is used to inject clothing treatment agent into the drum; ② the larger the distance between the distribution position of the clothing and the door body, the faster the injection speed of the clothing treatment agent injected by the liquid injection port is, so that the injection distance of the clothing treatment agent is longer and more clothing treatment agent contacts the clothing in the drum; ③ the larger the volume of the clothing, the greater the flow rate of the clothing treatment agent injected by the liquid injection port or the longer the injection time.

[0057] When the door is opened or closed, the clothing treatment agent shakes in the liquid storage chamber 141 and is easily attached to the inner wall surface of the liquid storage chamber 141, resulting in inaccurate observation or detection of the liquid level of the clothing treatment agent. In this embodiment, a guide rib 143 is provided on the inner wall surface of the liquid storage chamber 141. The guide rib 143 is used to guide the clothing treatment agent on the inner wall surface of the liquid storage chamber 141 to the bottom of the liquid storage chamber 141, thereby avoiding the problem of inaccurate observation or detection of the liquid level caused by the clothing treatment agent remaining on the inner wall surface of the liquid storage chamber 141.

[0058] Specifically, the guide rib 143 extends from top to bottom, and can quickly guide the clothes treating 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 may be coated on the inner wall surface of the liquid storage chamber 141. The liquid-repellent material has a repelling effect on the clothing treatment agent, reduces the adhesion of the clothing treatment agent, and allows the clothing treatment agent to quickly flow to the bottom of the liquid storage chamber 141.

[0060] Alternatively, the inner wall surface of the liquid storage chamber 141 is provided with a baffle rib, which is used to reduce the shaking amplitude of the clothing treatment agent in the liquid storage chamber 141 when the door is opened and closed; specifically, the baffle rib extends in the horizontal direction.

[0061] During the operation of the drum washing machine, the door body vibrates, causing the connection between the liquid feeding pipe 23 and the liquid feeding port 134 to become loose, resulting in the inability of the clothing treatment agent to smoothly enter the drum through the liquid feeding pipe 23 and the liquid feeding port 134. In this embodiment, the liquid feeding assembly 2 further includes a pipe joint, which includes a joint body 241; the joint body 241 is arranged at the liquid feeding port 134, and a sealing member 25 is provided between the joint body 241 and the liquid feeding port 134 to prevent the liquid in the drum from flowing back into the observation window cavity 133;

[0062] One end of the liquid feeding pipe 23 away from the liquid pump 22 is connected to one end of the joint body 241, and the other end of the joint body 241 can feed the clothes treating agent into the drum;

[0063] The joint body 241 is configured such that the liquid in the liquid injection tube 23 can be injected into the drum through the joint body 241, and the liquid in the drum cannot enter the liquid injection tube 23 through the joint body 241;

[0064] When the drum washing machine runs a washing program, the liquid pump 22 runs, and the clothing treatment agent in the liquid storage chamber 141 enters the drum through the liquid suction pipe 21, the liquid suction pump 22, the liquid injection pipe 23 and the joint body 241, thereby realizing intelligent injection of clothing treatment agent.

[0065] Specifically, the door frame includes a door lining 11 and a door inner shell 12, and the door lining 11 and the door inner shell 12 are both annular in shape as a whole; the door lining 11 is formed with an inner lining hole 111, and the door inner shell 12 is arranged on the door lining 11 and formed with an inner shell hole 121, and the inner lining hole 111 and the inner shell hole 121 are connected to form a door frame hole; the observation window 13 includes a base 131 and a window body 132, the base 131 is arranged between the door lining 11 and the door inner shell 12, and the window body 132 is arranged on the base 131, and the window body 132 passes through the inner shell hole 121 and protrudes in a direction away from the door inner shell 12 to form an observation window cavity 133; the side wall of the window body 132 is formed with a liquid injection port 134;

[0066] The door inner shell 12 is provided with a liquid storage chamber 141 on a side away from the door lining 11 and below the window 132; the door inner shell 12 is formed with a liquid discharge port facing the door lining 11; the door lining 11 is formed with a pipe hole 112 at a position corresponding to the liquid injection port 134;

[0067] One end of the liquid extraction tube 21 enters the observation window cavity 133 through the door frame hole and communicates with the liquid inlet of the liquid extraction pump 22, and the other end of the liquid extraction tube 21 passes through the tube hole 112 and communicates with the liquid discharge port;

[0068] The user can add clothing treatment agent to the liquid storage chamber 141 through the adding port 142 ; when the liquid pump 22 is running, the clothing treatment agent in the liquid storage chamber 141 can enter the liquid pump 22 through the liquid pumping pipe 21 , and then enter the drum through the liquid feeding pipe 23 and the joint body 241 .

[0069] Specifically, a pressing plate 31 is provided on the side of the door inner shell 12 away from the door lining 11 and at the left end of the door inner shell 12, a shaft sleeve 32 is provided at the upper end and the lower end of the pressing plate 31, a hinge plate 33 is provided on the front panel of the box body, a rotating shaft 34 is provided at the upper end and the lower end of the hinge plate 33, and the two rotating shafts 34 are respectively passed through the two shaft sleeves 32; when the shaft sleeves 32 rotate relative to the corresponding rotating shafts 34, the door body can rotate relative to the front panel, and then the door body can open or close the access opening;

[0070] A lock hook 35 is also provided on the right end of the door inner shell 12 away from the door lining 11, and a lock buckle is also provided on the front panel of the box body; when the door body closes the access opening, the lock hook 35 and the lock buckle cooperate to lock the door body;

[0071] A decorative plate 36 is provided on a side of the door lining 11 away from the door inner shell 12 . The decorative plate 36 is arranged on the door lining 11 via a decorative ring 37 .

[0072] The arrangement of the liquid dosing assembly 2 affects the length of the liquid dosing flow path. The arrangement of the liquid dosing assembly 2 is further described below. The liquid discharge port is located on the left side of the door inner shell 12, the pipe hole 112 is located on the left side of the door lining 11, and the liquid dosing port 134 is located on the left side of the window 132;

[0073] The liquid extraction pipe 21 and the liquid injection pipe 23 are arranged on the left side of the observation window cavity 133, and the liquid extraction pump 22 is arranged on the right side of the observation window cavity 133;

[0074] While fully utilizing the observation window cavity 133, the length of the liquid injection flow path is shortened, so that the clothes treating agent can quickly enter the drum through the liquid injection flow path.

[0075] Whether the user can conveniently observe the liquid level of the liquid storage chamber 141 directly affects whether the user can add clothing treatment agent in time. The structure of the liquid storage chamber 141 is further explained below; the door also includes a liquid storage shell 14, which is buckled on the side of the door inner shell 12 away from the door lining 11, and the liquid storage shell 14 and the door inner shell 12 together form the liquid storage chamber 141; the structure of the liquid storage chamber 141 is adapted to the structure of the door inner shell 12, and the liquid storage chamber 141 is arc-shaped; the liquid storage chamber 141 does not occupy the internal space of the observation window 13, and at the same time increases the volume of the liquid storage chamber 141; preferably, the door lining 11 and the door inner shell 12 are both circular, the liquid storage chamber 141 is arc-shaped, and the liquid storage chamber 141 and the door lining 11 and the door inner shell 12 are coaxially arranged; the liquid storage shell 14 is made of transparent material;
