[0002] Pulsator washing machines are clothes processing equipment that use electrical energy to generate mechanical action to wash clothes. Now they have entered thousands of households and are very popular. With the improvement of consumers' living standards, the requirements for washing machines are getting higher and higher.

[0003] Common pulsator washing machines on the market usually include a housing, a frame arranged on the housing, and a top cover installed on the frame. When the washing machine is working, the top cover needs to be opened first, and then the clothes are placed into the housing through the clothes loading port on the frame for washing. However, pulsator washing machines are generally installed in a storage rack, and the height of the storage rack is limited; if the height of the top cover after opening is too high, it will interfere with the storage rack, causing the top cover to fail to open and close normally.

[0004] At present, in order to solve the problem of the top cover being too high after opening, two top cover plates that are rotatably connected and foldable are usually used in related pulsator washing machines to reduce the height of the top cover after opening. However, after the top cover on the surrounding frame is folded, the top cover partially blocks the clothing loading port on the surrounding frame, making it inconvenient for users to put in clothes, which greatly reduces the user experience.

Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0059] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0060] When the washing machine is working, you need to open the top cover first, and then put the clothes into the washing machine through the clothes loading port on the frame for washing. However, the pulsator washing machine is generally installed in a storage rack, and the height of the storage rack is limited; if the height of the top cover after opening is too high, it will interfere with the storage rack, causing the top cover to not open and close normally.

[0061] At present, in some traditional pulsator washing machines, in order to solve the problem of the top cover being too high after opening, two top cover plates that are rotatably connected and foldable opposite to each other are usually used to reduce the height of the top cover after opening. However, after the top cover on the surrounding frame is folded opposite to each other, the top cover partially blocks the clothing loading port on the surrounding frame, causing inconvenience for users to put in clothes, greatly reducing the user experience. To solve this problem, the present application provides a pulsator washing machine.

[0062] For ease of understanding, the descriptions of up, down, left, right, front and back in this article are all based on the state of the washing machine when it is in use. The side of the pulsator washing machine facing the user is the outside, and the side facing the inside of the washing machine is the inside.

[0063] Figure 1 The figure is a schematic diagram of the structure of a pulsator washing machine in some embodiments. Figure 2 for Figure 1 Schematic diagram of the connection structure between the frame and the top cover of a pulsator washing machine. Figure 3 yes Figure 2 Schematic diagram of the structure of the clothing loading port with the middle top cover opened.

[0064] See also Figures 1 to 3 In some embodiments, the pulsator washing machine 100 may include a housing 10 , which may be configured to form an outer shell of the pulsator washing machine 100 . The appearance of the housing 10 may be designed according to the appearance of the washing machine, which is not limited herein.

[0065] In some embodiments, the pulsator washing machine 100 may include a drum assembly (not shown in the drawings). The drum assembly may be disposed inside the housing 10 , and the drum assembly may be vertically extended in the up-and-down direction.

[0066] In some embodiments, the drum assembly may include an outer drum disposed in the housing 10 and an inner drum disposed in the outer drum. A washing cavity may be provided in the inner drum, and the washing cavity may be used to accommodate clothes.

[0067] The inner drum can rotate relative to the outer drum, and there is a certain interval between the inner drum and the outer drum to form a water containing chamber. A water hole connected to the water containing chamber can be provided on the inner circumferential wall of the inner drum. The inner drum can discharge washing water to the outer drum through the water hole, and the washing water in the outer drum can also be discharged from the pulsator washing machine 100 through a drainage structure connected to the bottom of the outer drum.

[0068] In some embodiments, the pulsator washing machine 100 may include a frame 20, which may be disposed on the top of the housing 10. The frame 20 may be a frame structure, and a clothing loading port 21 may be disposed on the frame 20. The clothing loading port 21 may be opened at the center of the frame 20, and the clothing loading port 21 may be connected to the washing cavity in the drum assembly, so that the clothing may be placed in the washing cavity through the clothing loading port 21 for washing.

[0069] In some embodiments, the frame 20 may be made of high-strength plastic, such as PP, ABS, etc. A control panel may be provided at the front end of the upper portion of the frame 20, and a plurality of control buttons may be provided on the control panel to control different washing programs of the washing machine.

[0070] See also Figure 2 and Figure 3 In some embodiments, the pulsator washing machine 100 may further include a top cover 30. The top cover 30 may be disposed on the surrounding frame 20 and used to open or close the clothing loading port 21 on the surrounding frame 20. When washing clothes, the top cover 30 is opened, and then the clothes are placed into the washing chamber from the clothing loading port 21 in the middle of the surrounding frame 20, and then the clothing loading port 21 on the surrounding frame 20 is closed by the top cover 30.

[0071] Figure 4 for Figure 1 A schematic diagram of the structure of the top cover 30 of the medium-puller washing machine 100 from a top view. Figure 5 for Figure 4 A schematic diagram of the structure of the middle top cover 30 when viewed from bottom. Figure 6 for Figure 5 A schematic three-dimensional structural diagram of the first cover plate 31 of the middle top cover 30. Figure 7 for Figure 5 A schematic three-dimensional structural diagram of the second cover plate 32 of the middle top cover 30.

[0072] See also Figure 4 and Figure 6 In some embodiments, the top cover 30 may include a first cover plate 31 and a second cover plate 32 .

[0073] The first cover plate 31 and the second cover plate 32 may be connected to each other, and one end of the first cover plate 31 may be rotatably connected to the surrounding frame 20 .

[0074] The second cover plate 32 can slide relative to the first cover plate 31 in the front-rear direction of the first cover plate 31 .

[0075] The rear of the first cover plate 31 refers to the direction of the first cover plate 31 close to the connection with the frame 20; the front of the first cover plate 31 refers to the direction of the first cover plate 31 away from the connection with the frame 20. In this embodiment, sliding along the front-to-back direction of the first cover plate 31 is also sliding along the width direction of the first cover plate 31.

[0076] The second cover plate 32 can slide relative to the first cover plate 31 so as to move the second cover plate 32 to the end of the first cover plate 31 away from the connection with the surrounding frame 20, so that the top cover 30 can cover the clothing inlet 21, and the clothing inlet 21 is in a closed state.

[0077] When the second cover plate 32 moves to one end of the first cover plate 31 close to the connection with the surrounding frame 20, the second cover plate 32 can overlap with the first cover plate 31, and the clothing loading port 21 is in an open state.

[0078] When the user needs to do laundry, the second cover plate 32 can be pushed to move so that the first cover plate 31 and the second cover plate 32 overlap each other, and then the first cover plate 31 can be rotated to fully open the clothing inlet 21 on the surrounding frame 20. This effectively reduces the overall height of the top cover 30 and prevents the top cover 30 from interfering with the rack when it is opened. In addition, the second cover plate 32 and the first cover plate 31 overlap each other after sliding and shrinking, reducing the space occupied by the top cover 30, and will not block the clothing inlet 21 of the surrounding frame 20, which greatly facilitates the user's operation.

[0079] It is conceivable that in some other embodiments, the top cover 30 may also include a plurality of interconnected cover plates, such as three or four. The plurality of cover plates may slide toward the position where they are connected to the surrounding frame 20, so that the plurality of cover plates overlap each other, so as to further reduce the height of the top cover 30 after it is opened.

[0080] In some embodiments, the top cover 30 may further include a first sliding portion 33 , which may be disposed on the first cover plate 31 , and the first sliding portion 33 may be slidably matched with the second cover plate 32 , so that the second cover plate 32 slides in contact with the first cover plate 31 .

[0081] In some embodiments, the top cover 30 may further include a second sliding portion 34 , which may be disposed on the second cover plate 32 , and the second sliding portion 34 may slide relative to the first sliding portion 33 on the first cover plate 31 , so that the second cover plate 32 may slide against the first cover plate 31 .

[0082] It should be understood that the first sliding part 33 and the second sliding part 34 can be in various structural forms. For example, the first sliding part 33 and the second sliding part 34 are a sliding rod and a slider disposed on the sliding rod that can slide relative to each other, or a sliding rail and a pulley embedded in the sliding rail. As long as the sliding connection between the first sliding part 33 and the second sliding part 34 can be achieved, the second cover plate 32 can be slidably overlapped with the first cover plate 31.

[0083] See also Figures 5 to 7In some embodiments, the first sliding portion 33 may be a block-shaped structure fixed on the first cover plate 31 to form a sliding block. The second sliding portion 34 may be a groove-shaped structure opened on the second cover plate 32 to form a sliding groove.

[0084] The second sliding portion 34 may extend along the width direction of the second cover plate 32. The first sliding portion 33 on the first cover plate 31 may be connected to the second sliding portion 34 of the second cover plate 32, so that the second cover plate 32 can slide along the extension direction of the slide groove, so that the first cover plate 31 and the second cover plate 32 overlap or extend with each other.

[0085] See also Figure 6 In some embodiments, the first sliding portion 33 on the first cover plate 31 may be a T-shaped block structure. The T-shaped slider may pass through the groove-shaped second sliding portion 34 of the second cover plate 32 and abut against the plate surface of the second cover plate 32 to hook the second cover plate 32, so that the second cover plate 32 and the first cover plate 31 can slide against each other.

[0086] In some embodiments, two first sliding portions 33 may be provided on the first cover plate 31, and the two T-shaped first sliding portions 33 may be provided at intervals. The second sliding portion 34 on the second cover plate 32 may be configured as two corresponding sliding grooves to enhance the connection stability between the first cover plate 31 and the second cover plate 32.

[0087] In some embodiments, the second cover plate 32 can be disposed on the inner side of the first cover plate 31, that is, the second cover plate 32 is disposed on the lower side of the first cover plate 31. At this time, the T-shaped first sliding portion 33 on the inner side of the first cover plate 31 passes through the second sliding portion 34 on the second cover plate 32 and abuts against the inner side of the second cover plate 32, so that a sliding connection is formed between the first cover plate 31 and the second cover plate 32.

[0088] See also Figure 7 In some embodiments, a reinforcing rib 35 may be provided around the second sliding portion 34. The reinforcing rib 35 may be provided around the outer periphery of the second sliding portion 34, and the reinforcing rib 35 may be used to increase the strength of the slide groove of the second cover plate 32 to prevent the first sliding portion 33 from scratching the inner side of the second cover plate 32 or damaging the plate body of the second cover plate 32.

[0089] See also Figure 5 and Figure 6In some embodiments, the top cover 30 may further include a first limiting portion 311, which may be convexly disposed on a side where the first cover plate 31 is connected to the surrounding frame 20, and is used to abut against a side of the second cover plate 32 close to the first cover plate 31. When the second cover plate 32 slides toward the first cover plate 31 until it abuts against the first limiting portion 311 on the first cover plate 31, it cannot continue to slide toward the rotation connection side of the first cover plate 31, thereby achieving the contraction limiting of the second cover plate 32.

[0090] In some embodiments, the first limiting portion 311 may be configured as a plate-like structure, which may extend along the length direction of the first cover plate 31 and protrude from the inner side surface of the first cover plate 31 so as to abut against the side surface of the second cover plate 32. Of course, the first limiting portion 311 may be configured as a boss structure to abut against the side surface of the first cover plate 31 for limiting position.

[0091] See also Figure 5 and Figure 7 In some embodiments, the top cover 30 may further include a second stopper 321. The second stopper 321 may be protruding from an end of the second sliding portion 34 of the second cover plate 32 close to the first cover plate 31, and is used to abut against the first sliding portion 33 on the first cover plate 31.

[0092] When the second cover plate 32 slides in a direction away from the first cover plate 31 and the first sliding portion 33 on the first cover plate 31 abuts against the second limiting portion 321 on the second cover plate 32, the second cover plate 32 cannot continue to move in a direction away from the first cover plate 31 to achieve extension limiting of the top cover 30.

[0093] In some embodiments, the second position-limiting portion 321 is detachably connected to the inner side surface of the second cover plate 32. When the second cover plate 32 needs to be installed with the first cover plate 31, the second position-limiting portion 321 can be disassembled first, so that the block-shaped first sliding portion 33 on the first cover plate 31 enters into the groove-shaped second sliding portion 34 of the second cover plate 32, and then the second position-limiting portion 321 is fixed to the second cover plate 32.

Fig.12 for Fig.10 A schematic three-dimensional structural diagram of the second cover plate 32 of the middle top cover 30.

[0095] See also Figures 8 to 12 In some embodiments, the first sliding portion 33 on the first cover plate 31 may be a groove structure provided on the first cover plate 31 , which may extend along the width direction of the first cover plate 31 to form a slide groove.

[0096] The second sliding portion 34 on the second cover plate 32 may be a block structure disposed on the second cover plate 32 to form a sliding block.

[0097] The slider on the second cover plate 32 can be disposed in the slide groove of the first cover plate 31 and slide along the slide groove on the first cover plate 31 so that the first cover plate 31 and the second cover plate 32 overlap or stretch with each other.

[0098] See also Fig.11 In some embodiments, ribs 36 may be provided on both side edges of the first cover plate 31, and the first sliding portion 33 may be provided on the ribs 36 on both sides of the first cover plate 31 to increase the strength of the slide groove. Of course, the first sliding portion 33 may also be directly provided on both side edges of the plate body of the first cover plate 31.

[0099] In some embodiments, the second sliding portion 34 can be set on both sides of the outer edge of the second cover plate 32. The second sliding portion 34 can be an L-shaped slider. The L-shaped slider can hook the sliding grooves on both sides of the outer edge of the first cover plate 31 to achieve a sliding connection between the slider and the sliding groove.

[0100] See also Fig.10 In some embodiments, the second cover plate 32 may be located on the outer side of the first cover plate 31, that is, the second cover plate 32 is located on the upper side of the first cover plate 31. The L-shaped second sliding parts 34 on both sides of the second cover plate 32 may hold the first sliding parts 33 on both side edges of the first cover plate 31 from both sides, so that the second cover plate 32 can slide on the outer side of the first cover plate 31.

[0101] See also Fig.12 In some embodiments, the outer edges of both sides of the second cover plate 32 may be further provided with ribs 37, which may abut against the two side edges of the first cover plate 31 to guide the second cover plate 32 and the first cover plate 31 when they slide relative to each other, thereby preventing sliding dislocation between the first cover plate 31 and the second cover plate 32.

[0105] See also Fig.14 and Fig.15 In some embodiments, the first cover plate 31 may further include a first sandwich plate 312 and a second sandwich plate 313 connected to each other. The first sandwich plate 312 and the second sandwich plate 313 are spaced apart from each other to form a mounting cavity. The second cover plate 32 may be disposed in the mounting cavity between the first sandwich plate 312 and the second sandwich plate 313, and may be telescoped between the first sandwich plate 312 and the second sandwich plate 313.

[0106] In some embodiments, the first interlayer plate 312 is configured as the inner side surface of the first cover plate 31 , and the first sliding portion 33 can be disposed on the first interlayer plate 312 and extend along the width direction of the first interlayer plate 312 to form a slide groove.

[0107] See also Fig.16 In some embodiments, the second sliding portion 34 may be disposed on the inner side of the second cover plate 32. The second sliding portion 34 may be configured as a long strip-shaped slider, which may extend along the length direction of the second cover plate 32.

[0108] The second sliding portion 34 on the second cover plate 32 can slide in the extension direction of the first sliding portion 33 on the first interlayer plate 312, so that the second cover plate 32 can be inserted between the first interlayer plate 312 and the second interlayer plate 313, or extend from between the first interlayer plate 312 and the second interlayer plate 313.

[0109] See also Fig.17 and Fig.18 In some embodiments, the top cover 30 may further include a first limit block 332 and a second limit block 333 disposed at both ends of the first sliding portion 33. The first limit block 332 and the second limit block 333 can both abut against the block-shaped second sliding portion 34 on the second cover plate 32 to limit the travel of the second sliding portion 34.

[0110] See also Fig.17 In some embodiments, the first stopper 332 may be disposed at an end of the first sliding portion 33 close to the connection with the surrounding frame 20 . The second stopper 333 may be disposed at an end of the first sliding portion 33 far from the connection with the surrounding frame 20 .

[0111] See also Fig.19 and Fig. 20 In some embodiments, the second limit block 333 may be protruded on the second interlayer plate 313 and form an open cavity 335 between the second interlayer plate 312. The open cavity 335 allows the block-shaped second sliding portion 34 on the second cover plate 32 to be smoothly inserted into the first cover plate 31.

[0112] In some embodiments, the second limit block 333 may include an elastic arm 334, and the elastic arm 334 may protrude toward the second sandwich plate 313. The side of the elastic arm 334 facing the first limit block 332 is a vertical surface, which may abut against the second sliding portion 34 on the second cover plate 32 to limit the travel of the second sliding portion 34.

[0113] In some embodiments, the side of the elastic arm 334 facing the opening cavity 335 is an inclined surface, and the second sliding portion 34 of the second cover plate 32 also has a corresponding inclined surface, so that the second sliding portion 34 of the second cover plate 32 can squeeze the inclined surface of the elastic arm 334 inward from the opening cavity 335, and the elastic arm 334 is deformed so that the second sliding portion 34 can pass over the elastic arm 334 and enter the sliding groove of the first cover plate 31, thereby realizing the assembly of the second cover plate 32 and the first cover plate 31.

[0114] In some embodiments, the top cover 30 may further include a grip 38. The grip 38 may be disposed on a side of the second cover plate 32 away from the first cover plate 31, and the user may push the grip 38 to move the second cover plate 32 or rotate the first cover plate 31 to close or open the clothing inlet 21.

[0115] In summary, the pulsator washing machine 100 of the utility model includes a housing 10, a drum assembly arranged in the housing 10, a frame 20 placed on the top of the housing 10, and a top cover 30 arranged on the frame 20. The top cover 30 includes a first cover plate 31 and a second cover plate 32, and the second cover plate 32 is slidably connected to the first cover plate 31, so that the second cover plate 32 can slide in contact with the first cover plate 31, so that the top cover 30 includes a contracted state in which the first cover plate 31 and the second cover plate 32 overlap each other and an extended state in which the first cover plate 31 and the second cover plate 32 are separated from each other. When the user needs to wash clothes, the second cover plate 32 can be pushed to slide, so that the first cover plate 31 and the second cover plate 32 overlap each other, and then the first cover plate 31 is rotated to fully open the clothing inlet 21, which effectively reduces the overall height of the top cover 30 and prevents the top cover 30 from interfering with the storage rack when it is opened. Furthermore, the second cover plate 32 and the first cover plate 31 slide and shrink and overlap each other to reduce the space occupied by the top cover 30 and will not block the clothing inlet 21 of the surrounding frame 20, which greatly facilitates the user's operation and improves the user's experience.
