For example, a product or device comprising a series of components does not necessarily have to be limited to all the components clearly listed, but may include other components not clearly listed or inherent to these products or devices.

[0028] In the related art, in order to improve the user experience, a washing machine also includes a detergent automatic dispensing system, which eliminates the step of manual addition by automatically dispensing detergent. The detergent automatic dispensing system includes a detergent box and a dispensing component. An opening is provided on the inner wall of the clothing inlet of the surrounding frame. The detergent box is slidably installed in the opening. When the detergent box is installed in place in the opening, it is docked with the dispensing component located in the opening to dispense the detergent in the detergent box into the drum. However, when adding detergent, the user needs to manually slide and install the detergent box. If the detergent box is not installed in place, it may cause abnormal dispensing, such as air entering the detergent box or even detergent leakage, which causes dissatisfaction among users. To solve this problem, this application particularly proposes a pulsator washing machine.

[0029] For ease of understanding, the direction facing the user of the pulsator washing machine is defined as the front side, and the direction facing away from the user of the pulsator washing machine is defined as the rear side.

[0030] Figure 1 The structural schematic diagram of a pulsator washing machine according to some embodiments is shown.

[0031] See Figure 1 , a pulsator washing machine, including a cabinet 1, a drum 2, a surrounding frame 3 and a door cover 5. Among them, the cabinet 1 encloses a cylindrical shape extending up and down, and is overall rectangular. A base is provided at the bottom of the cabinet 1, and the base supports the cabinet 1. Components such as feet protruding downward and contacting the ground are installed on the base.

[0032] The simplified body 2 is arranged in the housing 1 and is used for washing clothes. The simplified body 2 includes an outer drum arranged in the housing 1 and an inner drum arranged in the outer drum, the inner drum is rotatable relative to the outer drum, a certain interval is provided between the inner drum and the outer drum to form a water containing cavity, a water hole communicating with the water containing cavity is provided on the inner peripheral wall of the inner drum, the inner drum can discharge washing water to the outer drum through the water hole, and the washing water is discharged from the pulsator washing machine through a drainage structure connected to the bottom of the outer drum.

[0033] The frame 3 is arranged on the top of the box body 1. It can be understood that in order to seal the top of the box body 1, the frame 3 is arranged along the edge of the box body 1 and can be buckled on the top of the box body 1. The middle part of the frame 3 has a clothing delivery port 31, which is connected to the inside of the simplified body 2. Specifically, the clothing delivery port 31 is connected to the inside of the inner drum, and the two are arranged correspondingly from top to bottom. The frame 3 is generally made of high-strength plastic, such as PP, ABS, etc., and a control panel is provided at the front end of the upper part of the frame 3, which is provided with multiple control buttons to control different washing programs of the washing machine. The frame 3 is also provided with any existing electrical components and / or pipelines such as a mounting structure and a delivery mechanism.

[0034] The door cover 5 is installed on the surrounding frame 3 to open or close the clothing inlet 31. For example, the door cover 5 is opened when the clothing needs to be washed, and after the clothing is put in, the clothing inlet 31 is closed by the door cover 5. Specifically, the door cover 5 can be turned upward and opened and closed on the surrounding frame 3, correspondingly closing or opening the clothing inlet 31 provided on the surrounding frame 3.

[0035] In some embodiments, the door cover 5 includes a first part 51 and a second part 52 that are hinged to each other, and one end of the first part 51 away from the second part 52 is hinged to the surrounding frame 3, so that the door cover 5 can be folded relative to the surrounding frame 3. At the same time, when the door cover 5 is opened, the first part 51 and the second part 52 are in a folded state, which is convenient for storing the door cover 5. When the door cover 5 closes the clothing inlet 31, the first part 51 and the second part 52 are flush and form an integrated type to completely close the clothing inlet 31. Among them, the first part 51 can be hinged to the rear end of the clothing inlet 31 on the surrounding frame 3, so that it can be folded forward to close the clothing inlet 31, which is in line with the user's use logic.

[0036] Of course, in some embodiments, the door cover 5 may be integrally formed, with one end of the door cover 5 hinged to the rear end of the clothing loading port 31 on the surrounding frame 3 , and the door cover 5 may be folded to open or close the clothing loading port 31 .

[0037] In some embodiments, an opening is formed on the inner wall of the clothing delivery port 31 of the surrounding frame 3, and a detergent box 4 is provided at the opening, which can be pulled out. The detergent box 4 is used to contain detergent, and the detergent may include laundry liquid or softener. A delivery mechanism is provided in the opening. When the detergent box 4 is installed in place, the detergent box 4 is docked with the delivery mechanism, so that the detergent is delivered into the simplified body 2 through the delivery mechanism to wash the clothes.

[0038] Figure 2 Shows a schematic diagram of the states of the door cover and the detergent box in a pulsator washing machine according to some embodiments Figure 1 , Figure 3 Shows a schematic diagram of the states of the door cover and the detergent box in a pulsator washing machine according to some embodiments Figure 2 .

[0039] Continuing to refer to Figure 2 and Figure 3 , in some embodiments, a docking area 42 is recessed in the rear wall of the detergent box 4. The feeding mechanism includes a docking portion 6 and a feeding portion communicating therewith. The docking portion 6 includes a nozzle and a check valve provided on the nozzle. When the detergent box 4 is installed in place, the nozzle enters the docking area 42, and the detergent just enters the feeding portion through the nozzle. A channel is provided in the feeding portion to lead the detergent into the tub 2. If the detergent box 4 is not fully pushed in place, it is difficult to confirm from the outside, and at this time the check valve opens, and the nozzle and the feeding portion may not operate normally, and liquid leakage is likely to occur.

[0040] Accordingly, in this embodiment, a convex portion 53 is protruded from the inner bottom of the door cover 5. The convex portion 53 is configured such that when the door cover 5 closes the laundry inlet 31, the convex portion 53 abuts against the outer end face of the detergent box 4 to push the detergent box 4 to a preset position. Wherein, the inner bottom of the door cover 5 refers to the side facing the bottom of the cabinet 1 when the door cover 5 closes the laundry inlet 31. When the door cover 5 closes the laundry inlet 31, the door cover 5 is in a closed state. At this time, the detergent box 4 should be installed in place in the opening under normal conditions, and the position where the detergent box 4 is located at this time is the preset position.

[0041] In this embodiment, by providing the convex portion 53 on the inner bottom of the door cover 5, when the door cover 5 is closed, the convex portion 53 will flip with the door cover 5. Thus, if the detergent box 4 is not installed in place due to user reasons, such as protruding from the opening portion, the convex portion 53 will contact the detergent box 4 before the door cover 5 reaches the position, and along with the movement of the door cover 5, the detergent box 4 will be pushed into the opening. Therefore, when the door cover 5 closes the laundry inlet 31, the detergent box 4 is also pushed to the preset position at the same time, so as to ensure that before the door cover 5 is closed for washing, the detergent box 4 is in the correct installation position, avoiding the situation that the detergent cannot be dispensed due to the failure to dock with the feeding mechanism due to improper installation, and improving the reliability of the washing machine.

[0042] It is understandable that the position and size of the convex portion 53 are only required to satisfy that when the door cover 5 closes the laundry inlet 31, it can be in contact with the outer end surface of the detergent box 4. In this embodiment, the convex portion 53 is provided on the inner bottom of the first part 51 of the door cover 5, so that it is closer to the detergent box 4. When the door cover 5 is flipped to close the laundry inlet 31, the convex portion 53 does not need to be set too large to be able to contact the detergent box 4, which is beneficial to reducing the size of the convex portion 53 and reducing the impact on the user when opening and closing the door cover 5.

[0043] In some embodiments, when the detergent box 4 is in a preset position, the outer end surface of the detergent box 4 is flush with the inner wall of the laundry inlet 31, so that the detergent box 4 does not interfere with the feeding of laundry and is convenient for the convex portion 53 to contact the detergent box 4.

[0044] In some embodiments, the surface of the convex portion 53 facing the detergent box 4 is a flat surface. When the door cover 5 closes the laundry inlet 31, this flat surface is parallel to the outer end surface of the detergent box 4. Thus, when the convex portion 53 contacts the detergent box 4, the whole surface pushes the detergent box 4 to move into the opening, and finally it is in the preset position.

[0045] In some embodiments, the convex portion 53 may further include a first connecting section and a second connecting section. The first connecting section protrudes from the inner bottom of the door cover 5, and one end of the second connecting section is connected to the first connecting section, and they are perpendicular to each other, so that the convex portion 53 forms an L-shaped shape. In this way, when the door cover 5 closes the laundry inlet 31, the second connecting section can directly abut against the outer end surface of the detergent box 4, thereby pushing the detergent box 4 to the preset position.

[0046] In some embodiments, the outer end surface of the detergent box 4 is provided with a convex rib 41. By providing the convex rib 41, the contact distance between it and the convex portion 53 can be reduced, which is convenient for setting the convex portion 53. At the same time, the convex rib 41 has a pointed end portion 411. When the door cover 5 closes the laundry inlet 31, the convex portion 53 abuts against the pointed end portion 411 to push the detergent box 4 to the preset position. By providing the pointed end portion 411, the contact between the convex portion 53 and the pointed end portion 411 is a line contact, which can more accurately push the detergent box 4 into the opening. It is understandable that the pointed end portion 411 is the part of the convex rib 41 that is farthest from the outer end surface of the detergent box 4 in the pulling direction of the detergent box 4, and it protrudes from other parts of the convex rib 41 in the pulling direction of the detergent box 4, so that when the convex portion 53 abuts against the convex rib 41, it first contacts the pointed end portion 411 and always maintains a line contact.

[0047] In some embodiments, the convex rib 41 can be a semi-circular structure, and the top edge of the convex rib 41 in the pulling direction of the detergent box 4 is the pointed end portion 411. The convex rib 41 can also be a triangular structure, and the edge of the triangular structure far from the outer end surface of the detergent box 4 is the pointed end portion 411. Of course, the convex rib 41 can also be other irregular shapes.

[0048] In this embodiment, for facilitating the pushing of the detergent box 4 when the convex portion 53 moves downward, a guiding surface 412 is formed at one end of the convex rib 41 away from the detergent box 4. The distance between the guiding surface 412 and the outer end surface of the detergent box 4 gradually increases in the direction from the top end to the bottom end of the detergent box 4. In this way, when the convex portion 53 moves downward, it moves downward along the guiding surface 412 and simultaneously pushes the detergent box 4 to move into the opening.

[0049] It can be understood that the guiding surface 412 can be a curved surface or a flat surface. When it is a curved surface, the corresponding central angle of the guiding surface 412 can be 90°, so as to ensure that the distance between the guiding surface 412 and the outer end surface of the detergent box 4 gradually increases. At this time, the edge of the guiding surface 412 away from the top end of the detergent box 4 constitutes a pointed end portion 411, and the overall cross-section of the convex rib 41 is triangular.

[0050] In this embodiment, the guiding surface 412 extends downward from the outer end surface of the detergent box 4. When the convex portion 53 approaches the convex rib 41, it can seamlessly transition from the outer end surface of the detergent box 4 to the guiding surface 412, improving the smoothness of pushing the detergent box 4.

[0051] In some embodiments, a buffer portion is provided at the portion of the convex portion 53 that abuts against the pointed end portion 411 to slow down the impact on the pointed end portion 411, prevent the pointed end portion 411 and the convex rib 41 from being scratched or subjected to excessive pressure, avoid deformation of the pointed end portion 411 and the convex rib 41 due to strong contact, and reduce their wear degree. Among them, the buffer portion can be a buffer layer 531 attached to the convex portion 53, which is made of a buffer material such as rubber.

[0052] Figure 4 Shows a schematic state of the door cover and the detergent box in a pulsator washing machine according to some embodiments Figure 3 , Figure 5 Shows a schematic state of the door cover and the detergent box in a pulsator washing machine according to some embodiments Figure 4 .

[0053] Continue to refer to Figure 4 and Figure 5 , in some other embodiments, a rotatable rolling wheel 532 is provided on the convex portion 53, and at least a part of the rolling wheel 532 protrudes from the surface of the convex portion 53 facing the detergent box 4. In this way, when the door cover 5 closes the laundry inlet 31, the rolling wheel 532 is in rolling contact with the convex rib 41, so as to utilize the rolling property to reduce the impact on the pointed end portion 411 and the convex rib 41, improve the service life of the convex portion 53 and the convex rib 41, and after the rolling wheel 532 rolls over the pointed end portion 411, it can abut against the outer end surface of the detergent box 4 again. At this time, the rolling wheel 532 constitutes the buffer portion.

[0054] Furthermore, at least part of the rolling wheel 532 is an elastic body, so that when the part rotates to contact the convex rib 41, the impact is further reduced and the buffering effect is improved. Preferably, the rolling wheel 532 is entirely an elastic body, such as made of rubber material, which has the best buffering effect.

[0055] In this embodiment, the end of the convex portion 53 away from the door cover 5 is partially opened to form a rotating cavity, a rotating shaft is provided in the rotating cavity, and the rolling wheel 532 is centrally sleeved on the rotating shaft and can rotate in the rotating cavity. When it contacts the outer end surface of the detergent box 4 and the guide surface 412, it rolls on it and simultaneously pushes the detergent box 4 to move into the opening to a preset position. It is understandable that the rolling wheel 532 is partially located outside the rotating cavity so that it can contact the outer end surface of the detergent box 4 and the guide surface 412.

[0056] In some embodiments, two or more detergent boxes 4 may be arranged side by side to respectively contain laundry detergent and softener, etc. At this time, two or more rolling wheels 532 may be arranged accordingly, each rolling wheel 532 corresponds to a detergent box 4, and are arranged at intervals along the arrangement direction of the detergent boxes 4.

[0057] In some embodiments, a door cover status detection device may be further provided in the washing machine to detect the opening and closing status of the door cover 5. In some cases, since the detergent box 4 protrudes too much from the inner wall of the clothing inlet 31, when the user closes the door cover 5, the protrusion 53 interferes with the top of the detergent box 4. At this time, the door cover 5 cannot be completely closed. The opening and closing status of the door cover 5 is detected by the door cover status detection device, and a message is sent to remind the user when it is not completely closed. This can prevent the washing machine from starting to wash when the detergent box 4 protrudes, thereby improving safety.
