Description

Technical Field

[0001] The embodiments of the present application relate to the field of home appliance technology, and in particular to a pulsator washing machine. Background Art

[0002] A pulsator washing machine is a common washing machine that is widely used as a consumer product for quickly washing clothes, etc. When using the pulsator washing machine, the user needs to open the cover of the pulsator washing machine, then put clothes and detergent into the pulsator washing machine, and then the clothes are washed by the pulsator washing machine.

[0003] The covers of conventional pulsator washing machines all open upward. When opening, the covers need to be rotated upward, so a certain opening height needs to be set. Moreover, after opening, the upward-opening cover occupies the upper space of the pulsator washing machine, which is inconvenient for the height arrangement of the pulsator washing machine. Especially for small-sized families, the user experience is poor. Utility Model Content

[0004] The embodiment of the present application provides a pulsator washing machine, which can reduce the occupied height of the cover plate, thereby reducing the requirement for the opening height, facilitating the layout of the pulsator washing machine, and improving the user experience.

[0005] In a first aspect, an embodiment of the present application provides a pulsator washing machine, comprising:

[0006] A box body, wherein an opening is formed on the top of the box body;

[0007] The barrel assembly has a washing cavity, which is connected to the barrel opening of the barrel assembly; the barrel assembly is arranged in the box body, and the barrel opening of the barrel assembly faces the opening;

[0008] The cover mechanism is arranged on the top of the box; the cover mechanism includes:

[0009] The cover plate assembly includes a first cover plate and a second cover plate, the second cover plate being rotatably arranged on one side of the top of the box body; the first cover plate being arranged on one end of the second cover plate facing away from the box body; the first cover plate being arranged on one side of the second cover plate in the height direction of the box body and being slidably connected to the second cover plate; when the first cover plate slides relative to the second cover plate, the cover plate assembly can be switched between an extended state and a retracted state; the length of the cover plate assembly in the extended state is greater than the length in the retracted state; the cover plate assembly can close the opening in the extended state, and can open at least a portion of the opening in the retracted state;

[0010] The limiting member is provided on the sliding path of the first cover plate and can limit the sliding position of the first cover plate relative to the second cover plate.

[0011] In this way, the sliding connection between the first and second cover plates allows the cover assembly to switch between an extended and stowed state. When the opening is opened, the first cover plate can slide and overlap relative to the second cover plate, assuming the stowed state, reducing the length of the cover assembly. When the cover mechanism rotates to open, the length of the cover assembly decreases, and a portion of the cover mechanism's height is stowed, thereby reducing the height occupied by the cover in the space above the opening. Therefore, the provision of the cover mechanism saves space. When the opening is fully opened, the cover mechanism occupies less space above the pulsator washing machine, thereby reducing the required height for the cover to open. This reduced height requirement facilitates the layout of the pulsator washing machine and improves user experience when users load and unload laundry. Because the stopper is located along the sliding path of the first cover plate and limits the sliding position of the first cover plate relative to the second cover plate, the stopper limits the sliding position of the first cover plate relative to the second cover plate when the first cover plate slides on the second cover plate, preventing the first cover plate from separating from the second cover plate while sliding on the second cover plate. At the same time, the limiting member can also limit the sliding position of the first cover plate relative to the second cover plate to prevent the first cover plate from colliding with other components on the refrigerator and causing damage due to excessive sliding during the sliding process.

[0012] In some embodiments of the present application, the cover mechanism further includes:

[0013] The sliding assembly includes a sliding seat and a sliding rail, wherein one of the sliding seat and the sliding rail is arranged on the first cover plate, and the other is arranged on the second cover plate; the sliding seat is slidably mounted on the sliding rail;

[0014] Wherein, along the sliding direction of the slide seat on the slide rail, the limiting member is opposite to the slide seat, and the limiting member is constructed to be able to prevent the slide seat from sliding on the slide rail when it abuts against the slide seat.

[0015] In this way, by arranging the slide and the slide rail, one of which is disposed on the first cover plate and the other on the second cover plate, the slide can slide stably along the slide rail, thereby improving the stability of the sliding connection between the first and second cover plates. Furthermore, because the sliding direction of the slide rail is consistent with the extension direction of the slide rail, the slide can only move along the extension direction of the slide rail. Therefore, the arrangement of the slide and the slide rail can also guide the sliding direction of the first cover plate. At the same time, because the limiter is disposed in the sliding direction of the slide rail and can abut against the slide, thereby preventing the slide from sliding on the slide rail, the arrangement of the limiter can limit the sliding position of the first cover plate relative to the second cover plate.

[0016] In some embodiments of the present application, a limiting member is provided at at least one end of the slide rail along the sliding direction of the slide seat.

[0017] In this way, by arranging the limiter at at least one end of the slide rail, the sliding of the slide seat can be restricted in the extension direction of the slide rail, that is, the sliding of the slide seat can be restricted, and it is convenient to fix or adjust the position of the limiter, thereby improving the integration of the structure.

[0018] In some embodiments of the present application, when the slide rail is provided on the second cover plate, the second cover plate has a thickened portion on the side in the width direction, and a groove is provided in the thickened portion. The groove extends along the sliding direction of the slide seat and forms the slide rail;

[0019] A limiting piece is provided at the end of the trough body in the extension direction, and the limiting piece is connected to the thickened portion.

[0020] In this way, by providing a thickened portion on the second cover plate and providing a groove in the thickened portion, the slide rail and the second cover plate can be integrally formed, which not only improves the stability of the connection between the slide rail and the second cover plate, but also improves processing efficiency and eliminates the need for installation and fixation of the slide rail. At the same time, a stopper is provided at the end of the groove in the extension direction, connecting the stopper to the thickened portion, facilitating installation and fixation of the stopper through the space in the groove.

[0021] In some embodiments of the present application, the edge of the first cover plate opposite to the thickened portion has a connecting portion, which is bent toward one side of the thickened portion and disposed in the groove body;

[0022] The connecting portion forms a sliding seat.

[0023] In this way, by setting a connecting portion on the first cover plate and forming the connecting portion into a slide seat, the slide seat and the first cover plate can be formed as one piece, which can not only improve the stability of the connection between the slide seat and the first cover plate, but also improve the processing efficiency without the need for installation and fixation.

[0024] In a second aspect, an embodiment of the present application further provides a pulsator washing machine, comprising:

[0025] A box body, wherein an opening is formed on the top of the box body;

[0026] The barrel assembly has a washing cavity, which is connected to the barrel opening of the barrel assembly; the barrel assembly is arranged in the box body, and the barrel opening of the barrel assembly faces the opening;

[0027] The cover mechanism is arranged on the top of the box; the cover mechanism includes:

[0028] The cover plate assembly includes a first cover plate and a second cover plate, the second cover plate being rotatably disposed on one side of the top of the box body; the first cover plate being disposed within an end of the second cover plate facing away from the box body and being slidably connected to the second cover plate; when the first cover plate slides relative to the second cover plate, the cover plate assembly can be switched between an extended state and a retracted state; the length of the cover plate assembly in the extended state is greater than the length in the retracted state; the cover plate assembly can close the opening in the extended state, and can open at least a portion of the opening in the retracted state;

[0029] The limiting member is provided on the sliding path of the first cover plate and can limit the sliding position of the first cover plate relative to the second cover plate.

[0030] In this way, the sliding connection between the first and second cover plates allows the cover assembly to switch between an extended and stowed state. When the opening is opened, the first cover plate can slide and overlap relative to the second cover plate, assuming the stowed state, reducing the length of the cover assembly. When the cover mechanism rotates to open, the length of the cover assembly decreases, and a portion of the cover mechanism's height is stowed, thereby reducing the height occupied by the cover in the space above the opening. Therefore, the provision of the cover mechanism saves space. When the opening is fully opened, the cover mechanism occupies less space above the pulsator washing machine, thereby reducing the required height for the cover to open. This reduced height requirement facilitates the layout of the pulsator washing machine and improves user experience when users load and unload laundry. Because the stopper is located along the sliding path of the first cover plate and limits the sliding position of the first cover plate relative to the second cover plate, the stopper limits the sliding position of the first cover plate relative to the second cover plate when the first cover plate slides on the second cover plate, preventing the first cover plate from separating from the second cover plate while sliding on the second cover plate. At the same time, the limiting member can also limit the sliding position of the first cover plate relative to the second cover plate to prevent the first cover plate from colliding with other components on the refrigerator and causing damage due to excessive sliding during the sliding process.

[0031] In some embodiments of the present application, the second cover plate is provided with a receiving groove, and the first cover plate is disposed in the receiving groove;

[0032] The cover mechanism also includes:

[0033] The sliding assembly includes a sliding groove and a slider, wherein one of the sliding groove and the slider is arranged on the groove wall of the receiving groove, and the other is arranged on the first cover plate; the slider is arranged in the sliding groove;

[0034] Wherein, along the sliding direction of the slider in the sliding groove, the limiting member is opposite to the slider, and the limiting member is constructed to be able to prevent the slider from sliding in the sliding groove when it abuts against the slider.

[0035] In this way, by providing a receiving groove in the second cover plate, the first cover plate can be accommodated. In addition, the groove wall of the receiving groove can also limit the moving direction of the first cover plate, preventing the first cover plate from colliding with other components during sliding, causing damage and leading to poor sliding. By providing the slider and the slide groove, one of them is provided on the first cover plate and the other is provided on the second cover plate. Since the slider can slide stably along the slide groove, the stability of the sliding connection between the first cover plate and the second cover plate is improved. At the same time, since the limiter is provided in the sliding direction of the slider and can abut against the slider, thereby preventing the slider from sliding in the slide groove, the provision of the limiter can limit the sliding position of the first cover plate relative to the second cover plate.

[0036] In some embodiments of the present application, the first cover plate has a slider on a side facing the opening, and the slider has a pressing surface and a mating surface in the sliding direction; the slot wall of the accommodating slot has a slot at a position corresponding to the slider; the box body has a front side wall and a rear side wall in the depth direction, the limiter is provided on a side of the slot facing the front side wall and is located on a side of the slot facing the opening; the limiter has a limit portion on a side facing the slot;

[0037] When the pressing surface slides to the limiting portion, the limiting portion is configured to elastically deform under the pressure of the pressing surface, so that the slider continues to slide along the sliding groove;

[0038] When the matching surface slides to the limiting portion, the limiting portion is also configured to be able to match with the matching surface to limit the slider from continuing to slide in the reverse direction.

[0039] In this way, by providing a pressing surface on the slider and a limiting portion on the limiting member, during assembly, the limiting portion and the pressing surface cooperate to directly install the first cover plate into the second cover plate, thereby facilitating the connection of the first cover plate and the second cover plate, thereby improving assembly efficiency. At the same time, by providing a mating surface on the slider and cooperating with the limiting portion on the limiting member, the first cover plate can be restricted from sliding out of the second cover plate, thereby preventing the first cover plate and the second cover plate from separating during use.

[0040] In some embodiments of the present application, the second cover is rotatably disposed on the top of the box body adjacent to one side of the rear side wall of the box body.

[0041] In this way, the user can operate from the front side of the box body, rotate the cover assembly, and open the opening, which is convenient for the user's operation.

[0042] In some embodiments of the present application, the side of the cover assembly facing away from the opening in the unfolded state is defined as the front side. Along the length direction of the cover assembly, the dimension of the first cover plate exposed on the front side of the cover assembly is H1, and the dimension of the second cover plate exposed on the front side of the cover assembly is H2. H1 and H2 satisfy the following requirements:

[0043] 0.5 ​

[0044] This minimizes the size difference between the first and second cover plates, while the overall size of the cover mechanism is the sum of their sizes. Therefore, when they overlap, the overlapping portion accounts for a larger portion of the overall size of the cover mechanism, significantly reducing the opening height. If H1 / H2 is less than 0.5, the first cover plate is too small, and the size difference between the first and second cover plates is relatively large. As the overall size of the cover mechanism is the sum of their sizes, the overlapping portion accounts for a smaller portion of the overall size of the cover mechanism when the first and second cover plates slide and overlap. The height occupied by the cover mechanism after opening remains relatively high, with little effect on reducing height. If H1 / H2 is greater than 1.5, the second cover plate is too small, resulting in a smaller portion of the overall size of the cover mechanism when the first and second cover plates slide and overlap. The height occupied by the cover mechanism after opening remains relatively high, with little effect on reducing height. The design of the first and second cover plates improves the ease of sliding overlap and operation, effectively reducing the size of the cover mechanism after sliding overlap.

[0066] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0067] A pulsator washing machine is a common washing machine that is widely used as a consumer product for quickly washing clothes, etc. When using the pulsator washing machine, the user needs to open the cover of the pulsator washing machine, then put clothes and detergent into the pulsator washing machine, and then the clothes are washed by the pulsator washing machine.

[0068] The covers of conventional pulsator washing machines all open upwards. Since the covers need to rotate upwards when opened, a certain opening height needs to be set. Furthermore, after opening, the upward-opening cover occupies the upper space of the pulsator washing machine, making it inconvenient to arrange the washing machine in the height direction. Especially for small households, high space utilization is required, so conventional pulsator washing machines provide a poor user experience. In the prior art, there are methods that provide a bent cover to reduce the height limit of the cover. However, the bent structure uses a rotating connection, which, on the one hand, has a shorter service life, and on the other hand, may cause pinching when rotating.

[0069] After repeated deliberation and verification, the inventors discovered that if the cover of a pulsator washing machine is configured as multiple separate units and then connected by sliding, they can be stacked together when the cover is opened. This reduces the cover's height and lowers the opening height requirement. This also frees up space above the washing machine. When fully opened, the cover occupies less space above the washing machine, facilitating the layout of the washing machine and improving the user experience. The sliding connection also has a relatively long service life and prevents pinching.

[0070] Figure 1 This is one of the structural schematic diagrams of the pulsator washing machine provided in an embodiment of the present application. Figure 2 This is the second structural schematic diagram of the pulsator washing machine provided in an embodiment of the present application.

[0071] like Figure 1 and Figure 2 As shown, the pulsator washing machine 200 provided in the embodiment of the present application includes a housing 201. An opening 202 is formed at the top of the housing 201. The opening 202 is used for users to put clothes.

[0072] The pulsator washing machine 200 provided in the embodiment of the present application further includes a cover mechanism 100. The cover mechanism 100 is rotatably mounted on the housing 201 and is used to open or close the opening 202. The cover mechanism 100 has an extended state and a retracted state.

[0073] When the cover mechanism 100 is in the deployed state, it can close the opening 202. When the cover mechanism 100 is in the retracted state, it can open at least a portion of the opening 202.

[0074] The pulsator washing machine 200 of the present application also includes a drum assembly. The drum assembly comprises an inner tub and an outer tub. The outer tub is fixedly mounted within the housing 201. The inner tub is rotatably mounted within the outer tub and defines a washing chamber that communicates with the drum opening of the drum assembly. The drum opening faces the opening 202. The washing chamber is used to hold clothing.

[0075] The pulsator washing machine 200 in the present application further includes a motor. The motor is arranged in the housing 201 and is connected to the inner tub to drive the inner tub to rotate.

[0076] The cover mechanism 100 includes a cover assembly. The cover assembly includes at least two cover plates, which are slidably connected. When the two connected cover plates slide relative to each other, the length of the cover mechanism 100 can be changed, so that the cover mechanism 100 can be switched between an expanded state and a retracted state.

[0077] like Figure 1 As shown, when closing the opening 202 , at least two covers slide and unfold to an unfolded state, and the cover mechanism 100 covers the opening 202 , thereby shielding at least a portion of the opening 202 .

[0078] like Figure 2 As shown, when the opening 202 is opened, the cover mechanism 100 rotates to open, and at least two cover plates slide and overlap to a storage state, thereby storing and stacking some of the cover plates.

[0079] When the opening 202 is opened, the cover mechanism 100 can slide and overlap at least two covers by pushing and pulling, so that part of the surface of the cover is folded together. When the cover mechanism 100 is rotated to open, the height of part of the cover is stored, so that the height occupied by the cover in the space above the opening is reduced, saving space. After the opening 202 is fully opened, the space occupied by the cover mechanism 100 on the upper part of the pulsator washing machine 200 becomes smaller, thereby reducing the requirements for the opening height, facilitating the layout of the pulsator washing machine 200, and facilitating the user to take and put clothes, thereby improving the user experience.

[0080] In some embodiments of the present application, the cover mechanism 100 is rotatably mounted on the top of the pulsator washing machine 200, and the rotation axis of the cover mechanism 100 is located behind the opening 202, thereby facilitating user operation. However, the present application is not limited thereto. In some other embodiments of the present application, the rotation axis of the cover mechanism 100 may also be located on the left side, right side, or even in front of the opening 202.

[0081] Figure 3 for Figure 1 One of the structural schematic diagrams of the cover mechanism of the pulsator washing machine shown. Figure 4 for Figure 3 Schematic diagram of the exploded structure of the cover mechanism shown. Figure 5 for Figure 1 The second structural diagram of the cover mechanism of the pulsator washing machine is shown. Figure 6 for Figure 5 Schematic diagram of the exploded structure of the cover mechanism shown.

[0082] like Figures 3 to 6As shown, in some embodiments of the present application, the cover plate assembly includes a first cover plate 10 and a second cover plate 20. The second cover plate 20 is rotatably arranged on one side of the top of the box body 201, and the first cover plate 10 is arranged on the end of the second cover plate 20 away from the box body 201.

[0083] Along the height direction of the box body 201 , the first cover plate 10 is disposed on one side of the second cover plate 20 and is slidably connected to the second cover plate 20 .

[0084] When the first cover plate 10 slides relative to the second cover plate 20, the cover plate assembly can switch between the deployed state and the retracted state. The length of the cover plate assembly in the deployed state is greater than the length in the retracted state. The cover plate assembly can close the opening 202 in the deployed state, and can open at least a portion of the opening 202 in the retracted state.

[0085] In the figure, the first direction x represents the length direction of the cover assembly, and the second direction y represents the width direction of the cover assembly.

[0086] When closing the opening 202 , the first cover 10 can be slid and unfolded relative to the second cover 20 to an unfolded state, thereby lengthening the cover assembly. The cover mechanism 100 covers the opening 202 , thereby closing the opening 202 .

[0087] When the opening 202 is opened, the first cover 10 can be slid and overlapped relative to the second cover 20, thereby reducing the length of the cover assembly. When the cover mechanism 100 is rotated to open, due to the reduction in the length of the cover assembly, part of the height of the cover mechanism 100 is stored, thereby reducing the height occupied by the cover in the space above the opening.

[0088] The setting of the cover mechanism 100 saves space, so that after the opening 202 is fully opened, the space occupied by the cover mechanism 100 on the upper part of the pulsator washing machine 200 becomes smaller, thereby reducing the requirements for the opening height, facilitating the layout of the pulsator washing machine 200, and facilitating the user to take and put clothes, thereby improving the user experience.

[0089] It can be understood that the cover plate assembly may also include three or more cover plates that are connected in a sliding manner.

[0090] In some embodiments of the present application, the cover mechanism 100 further includes a limiter 33 , which is disposed on a sliding path of the first cover 10 and is capable of limiting a sliding position of the first cover 10 relative to the second cover 20 .

[0091] The stopper 33 prevents the first cover plate 10 from separating from the second cover plate 20 when sliding on the second cover plate 20. At the same time, the stopper 33 can also prevent the first cover plate 10 from colliding with other components and causing damage due to excessive sliding during the sliding process.

[0092] In some embodiments of the present application, the cover mechanism 100 further includes a sliding assembly 30. The sliding assembly 30 is disposed between the first cover 10 and the second cover 20, enabling the first cover 10 and the second cover 20 to switch between a stowed state in which they slide and overlap, and a deployed state in which they slide and unfold. The first cover 10 is slidably connected to the second cover 20 via the sliding assembly 30.

[0093] The first cover plate 10 and the second cover plate 20 are connected by the sliding component 30. The arrangement of the first cover plate 10 and the second cover plate 20 has a small number of components and high processing and production efficiency. In addition, it is only necessary to connect the first cover plate 10 to the second cover plate 20 through the sliding component 30, and there are fewer assembly steps. In addition, the assembly of the first cover plate 10 and the second cover plate 20 has larger plates, which is convenient for grabbing and assembling, and has high installation efficiency. This can make the structure of the cover mechanism 100 simple and convenient for processing, production and installation.

[0094] The sliding direction of the first cover plate 10 and the rotation axis direction of the second cover plate 20 are perpendicular to each other.

[0095] In some embodiments of the present application, a handle 11 is further provided on the first cover plate 10. The handle 11 is provided on a side of the first cover plate 10 away from the second cover plate 20. The handle 11 is used for a user to hold so as to facilitate sliding the first cover plate 10 relative to the second cover plate 20.

[0096] The handle 11 may be a protrusion protruding from the first cover plate 10 , or may be a groove formed on the first cover plate 10 .

[0097] like Figure 3 and Figure 4 As shown, in some embodiments of the present application, the sliding assembly 30 includes a slide 31 and a slide rail 32. The slide 31 is disposed on the first cover plate 10, and the slide rail 32 is disposed on the second cover plate 20. The slide 31 is slidably mounted on the slide rail 32. The slide 31 and the slide rail 32 cooperate with each other to enable the first cover plate 10 to slide relative to the second cover plate 20.

[0098] The arrangement of the slide 31 and the slide rail 32 allows the slide 31 to slide stably along the slide rail 32, thereby improving the stability of the sliding connection between the first cover 10 and the second cover 20. Furthermore, because the sliding direction of the slide rail 32 coincides with its extension direction, the slide 31 moves only in the extension direction of the slide rail 32. Therefore, the arrangement of the slide 31 and the slide rail 32 also guides the sliding direction of the first cover 10. Furthermore, because the slide 31 and the slide rail 32 can be customized, the precision of the movement of the first cover 10 on the second cover 20 is improved.

[0099] It is understandable that in some other embodiments of the present application, the slide seat 31 may be provided on the second cover plate 20 , and the slide rail 32 may be provided on the first cover plate 10 .

[0100] In some embodiments of the present application, a stopper 33 is provided on the slide rail 32. The stopper 33 is opposite the slide 31 along the sliding direction of the slide 31 on the slide rail 32. When the stopper 33 abuts the slide 31, it can prevent the slide 31 from sliding on the slide rail 32, thereby limiting the sliding distance of the slide 31.

[0101] The setting of the limit member 33 can prevent the slide 31 from sliding out from the two ends of the slide rail 32 when moving on the slide rail 32, causing the first cover plate 10 and the second cover plate 20 to separate from each other when sliding. At the same time, the limit member 33 can also limit the sliding distance of the slide 31, thereby preventing the first cover plate 10 from colliding with other components due to sliding during the sliding process and causing damage.

[0102] In some embodiments of the present application, along the sliding direction of the slide seat 31 , the limiting member 33 is provided at at least one end of the slide rail 32 .

[0103] By arranging the limiter 33 at at least one end of the slide rail 32, the sliding of the slide seat 31 can be restricted in the extension direction of the slide rail 32, that is, the sliding of the slide seat 31 can be restricted, and it is convenient to fix or adjust the position of the limiter 33, thereby improving the integration of the structure.

[0104] Optionally, the limiting members 33 are provided at both ends of the slide rail 32 , thereby limiting the sliding of the first cover plate 10 from both sides.

[0105] Specifically, one of the stoppers 33 is located at one end of the slide rail 32 near the first cover plate 10 to prevent the first cover plate 10 from separating from the second cover plate 20 when deployed. Another stopper 33 is located at one end of the slide rail 32 near the rotation axis of the second cover plate 20 to prevent the first cover plate 10 from sliding beyond the range when sliding and stacking, thereby colliding with other components and causing damage. It also prevents the first cover plate 10 from sliding off the slide rail 32 and becoming stuck in other components, causing it to be unable to deploy.

[0106] like Figure 5 and Figure 6 As shown, in some embodiments of the present application, the sliding assembly 30 includes two sliding assemblies 30, one sliding assembly 30 is provided on one side of the first cover plate 10 and the second cover plate 20, and the other sliding assembly 30 is provided on the other side of the first cover plate 10 and the second cover plate 20.

[0107] By respectively arranging sliding components 30 on both sides of the first cover plate 10 and the second cover plate 20, the first cover plate 10 and the second cover plate 20 are connected on both sides respectively. Compared with connecting by only one sliding component 30, the connection positions are increased, which can make the connection between the first cover plate 10 and the second cover plate 20 more stable. At the same time, connecting from both sides can also facilitate the processing and installation of the sliding components 30 on both sides of the first cover plate 10 and the second cover plate 20, thereby improving the efficiency of processing and installation.

[0108] In some other embodiments of the present application, the two sliding components 30 may also be disposed in the middle of the first cover plate 10 and the second cover plate 20 , or respectively disposed on one side and the middle of the first cover plate 10 and the second cover plate 20 .

[0109] In some embodiments of the present application, the slide rail 32 is a groove, and the slide seat 31 is a protrusion formed on the first cover plate 10 so as to cooperate with the groove.

[0110] However, the present invention is not limited thereto. In some other embodiments, the slide seat 31 may be a component that is separately processed and formed according to the structure of the slide rail 32 and is fixed to the first cover plate 10 by installation, thereby facilitating assembly.

[0111] In some embodiments of the present application, when the slide rail 32 is provided on the second cover plate 20, the second cover plate 20 has a thickened portion 22 on the side in the second direction y, that is, the width direction, and the thickened portion 22 has a groove body, which extends along the sliding direction of the slide seat 31 and forms the slide rail 32.

[0112] A limiting member 33 is provided at the end of the groove body in the extension direction, and the limiting member 33 is connected to the thickened portion 22 .

[0113] By forming a thickened portion 22 on the second cover plate 20, forming a groove body in the thickened portion 22, and forming or providing a limit member 33 at the end of the groove body in the extension direction, the slide rail 32 and the second cover plate 20 can be integrally formed, which can not only improve the stability of the connection between the slide rail 32 and the second cover plate 20, but also improve the processing efficiency without the need for installation and fixation.

[0114] The edge of the first cover plate 10 opposite to the thickened portion 22 has a connecting portion 12 , which is bent toward one side of the thickened portion 22 and disposed within the groove. The connecting portion 12 forms a sliding seat 31 .

[0115] By forming a connecting portion 12 on the first cover plate 10 and forming the sliding seat 31 through the connecting portion 12, the sliding seat 31 and the first cover plate 10 can be integrally formed, which can not only improve the stability of the connection between the sliding seat 31 and the first cover plate 10, but also improve the processing efficiency without the need for installation and fixation.

[0116] However, the present invention is not limited thereto. In some other embodiments, the slide rail 32 may be a separately processed component, which is fixed to the second cover plate 20 by installation, thereby facilitating assembly.

[0117] In some embodiments of the present application, when the cover mechanism 100 is unfolded to cover the opening 202, the first cover 10 is located above the second cover 20. It is understood that in other embodiments of the present application, the first cover 10 can also be located below the second cover 20.

[0118] Figure 7 This is one of the structural schematic diagrams of another cover mechanism provided in an embodiment of the present application. Figure 8 for Figure 7 Schematic diagram of the exploded structure of the cover mechanism shown. Figure 9 for Figure 7 The second structural diagram of the cover mechanism shown. Figure 10 for Figure 9 Schematic diagram of the exploded structure of the cover mechanism shown.

[0119] like Figures 7 and 8 As shown, in some other embodiments of the present application, the cover plate assembly includes a first cover plate 10 and a second cover plate 20, and the second cover plate 20 is rotatably arranged on one side of the top of the box body 201. The first cover plate 10 is arranged in an end of the second cover plate 20 away from the box body 201 and is slidably connected to the second cover plate 20.

[0120] When the first cover plate 10 slides relative to the second cover plate 20, the cover plate assembly can switch between the deployed state and the retracted state. The length of the cover plate assembly in the deployed state is greater than the length in the retracted state. The cover plate assembly can close the opening 202 in the deployed state, and can open at least a portion of the opening 202 in the retracted state.

[0121] When closing the opening 202 , the first cover 10 can be slid and unfolded relative to the second cover 20 to an unfolded state, thereby lengthening the cover assembly. The cover mechanism 100 covers the opening 202 , thereby closing the opening 202 .

[0122] When the opening 202 is opened, the first cover 10 can slide relative to the second cover 20 and be stored in one end of the second cover 20, thereby reducing the length of the cover assembly. When the cover mechanism 100 is rotated to open, due to the reduction in the length of the cover assembly, part of the height of the cover mechanism 100 is stored, thereby reducing the height occupied by the cover in the space above the opening.

[0123] The setting of the cover mechanism 100 saves space, so that after the opening 202 is fully opened, the space occupied by the cover mechanism 100 on the upper part of the pulsator washing machine 200 becomes smaller, thereby reducing the requirements for the opening height, facilitating the layout of the pulsator washing machine 200, and facilitating the user to take and put clothes, thereby improving the user experience.

[0124] In some embodiments of the present application, the second cover plate 20 is provided with a receiving groove 21 , and the first cover plate 10 is received in the receiving groove 21 and extends out of the receiving groove 21 through the sliding assembly 30 .

[0125] Specifically, a receiving groove 21 is defined at one end of the second cover plate 20 facing the first cover plate 10 .

[0126] The receiving groove 21 can accommodate the first cover plate 10. In addition, the groove wall of the receiving groove 21 can also limit the moving direction of the first cover plate 10, preventing the first cover plate 10 from colliding with other components during the sliding process, causing damage and leading to poor sliding.

[0127] like Figure 9 and Figure 10 As shown, in some embodiments of the present application, the sliding assembly 30 includes a slide groove 34 and a slider 35. The slide groove 34 is provided on the side wall of the receiving groove 21, and the slider 35 is provided on the side of the first cover plate 10 facing the slide groove 34 and is disposed within the slide groove 34. The slide groove 34 and the slider 35 cooperate with each other to enable the first cover plate 10 to slide relative to the second cover plate 20.

[0128] The slider 35 and the chute 34 allow the slider 35 to slide stably along the chute 34, thereby guiding the sliding direction of the first cover plate 10 and improving the stability of the sliding connection between the first cover plate 10 and the second cover plate 20. The slider 35 and the chute 34 can be machined as needed, thereby improving the accuracy of the movement of the first cover plate 10.

[0129] It is understandable that in some other embodiments of the present application, the slider 35 can also be provided on the side wall of the accommodating groove 21 , and the sliding groove 34 can be provided on the side of the first cover plate 10 facing the slider 35 .

[0130] It is understandable that in some other embodiments of the present application, the accommodating groove 21 can be provided on the first cover plate 10 , the sliding groove 34 can be provided on the first cover plate 10 , and the sliding block 35 can be provided on the second cover plate 20 .

[0131] In some embodiments of the present application, along the sliding direction of the slider 35 in the sliding groove 34, the limit member 33 is opposite to the slider 35, and the limit member 33 is constructed to be able to prevent the slider 35 from sliding in the sliding groove 34 when it abuts against the slider 35.

[0132] The stopper 33 prevents the first cover plate 10 from separating from the second cover plate 20 when sliding on the second cover plate 20. At the same time, the stopper 33 can also prevent the first cover plate 10 from colliding with other components and causing damage due to excessive sliding during the sliding process.

[0133] In some embodiments of the present application, when the cover mechanism 100 is unfolded to cover the opening 202, the chute 34 is located on the side of the second cover 20 facing the opening 202. This prevents debris from entering the chute 34 and causing jamming or damage.

[0134] In some embodiments of the present application, the sliding assembly 30 includes two sliding grooves 34 , which are provided on the same side wall of the accommodating groove 21 and are symmetrically arranged.

[0135] Specifically, the receiving groove 21 is provided in the middle of the second cover plate 20 , and the two sliding grooves 34 can be symmetrically provided on the second cover plate 20 , so that the second cover plate 20 has a symmetrical structure as a whole.

[0136] By setting two sliding components 30, compared with connecting through only one sliding component 30, the connection positions are increased, which can make the connection between the first cover plate 10 and the second cover plate 20 more stable. At the same time, the symmetrically arranged sliding components 30 can also make the center of gravity of the cover mechanism 100 on the center line, making the first cover plate 10 and the second cover plate 20 more stable when sliding relative to each other.

[0137] In some embodiments of the present application, the two sliding grooves 34 may also be respectively provided on both sides of the same side wall of the accommodating groove 21, or the two sliding grooves 34 may also be respectively provided on two opposite side walls.

[0138] In some embodiments of the present application, the slider 35 is provided on a side of the first cover plate 10 close to the second cover plate 20 , so as to facilitate processing and convenient installation.

[0139] In some embodiments of the present application, the first cover plate 10 has a slider 35 on the side facing the opening 202. The slider 35 has a pressing surface 351 and a mating surface 352 in the sliding direction. A slot 34 is formed on the wall of the receiving slot 21 at a position corresponding to the slider 35. The housing 201 has a front sidewall and a rear sidewall in the depth direction. A stopper 33 is provided on the side of the slot 34 facing the front sidewall and on the side of the slot 34 facing the opening 202. The side of the stopper 33 facing the slot 34 has a stopper portion 331.

[0140] When the pressing surface 351 slides to the limiting portion 331 , the limiting portion 331 is configured to elastically deform under the pressure of the pressing surface 351 , so that the slider 35 continues to slide along the sliding groove 34 .

[0141] When the mating surface 352 slides to the limiting portion 331 , the limiting portion 331 is also configured to be able to cooperate with the mating surface 352 to limit the slider 35 from continuing to slide in the reverse direction.

[0142] By providing a pressing surface 351 on the slider 35 and a limiting portion 331 on the limiting member 33, during assembly, the limiting portion 331 cooperates with the pressing surface 351 to directly insert the first cover plate 10 into the second cover plate 20, thereby facilitating the connection between the first cover plate 10 and the second cover plate 20 and improving assembly efficiency. Furthermore, by providing a mating surface 352 on the slider 35, which cooperates with the limiting portion 331 on the limiting member 33, the first cover plate 10 can be restricted from sliding out of the second cover plate 20, preventing the first cover plate 10 and the second cover plate 20 from separating during use.

[0143] In some embodiments of the present application, the second cover plate 20 is rotatably disposed on the top of the box body 201 adjacent to one side of the rear side wall of the box body 201 .

[0144] The user can operate from the front side of the box body 201, rotate the cover assembly, and open the opening 202 for easy operation. However, in some other embodiments of the present application, the second cover plate 20 can also be adjacent to the left side wall, right side wall, or even the front side wall of the box body 201.

[0145] Figure 11 for Figure 1 Schematic diagram of the size and structure of the cover mechanism shown. Figure 12 for Figure 1 The diagram shows the dimensions and structure of a pulsator washing machine.

[0146] like Figure 11 As shown, in some embodiments of the present application, the side of the cover assembly facing away from the opening 202 in the deployed state is defined as the front side, and the length direction of the cover mechanism 100 is the sliding direction of the cover. Along the length direction of the cover assembly, the dimension of the first cover 10 exposed at the front side of the cover assembly is H1, and the dimension of the second cover 20 exposed at the front side of the cover assembly is H2. H1 and H2 satisfy the following relationship: 0.5 ≤ H1 / H2 ≤ 1.5.

[0147] If H1 / H2 is less than 0.5, the first cover plate 10 will be relatively too small, and the size difference between the first cover plate 10 and the second cover plate 20 will be relatively large. The overall size of the cover mechanism 100 is the sum of the sizes of the first cover plate 10 and the second cover plate 20. As a result, when the first cover plate 10 and the second cover plate 20 slide and overlap, the overlapping part occupies too small a proportion of the overall size of the cover mechanism 100. The height occupied by the cover mechanism 100 after opening is still relatively large, and the effect of reducing the height is not obvious.

[0148] If H1 / H2 is greater than 1.5, the second cover plate 20 will be relatively too small, resulting in the overlapping portion occupying too small an overall size of the cover mechanism 100 when the first cover plate 10 and the second cover plate 20 slide and overlap. The height occupied by the cover mechanism 100 after opening is still relatively large, and the height reduction effect is not obvious.

[0149] When 0.5 ≤ H1 / H2 ≤ 1.5 in this application, the size difference between the first cover plate 10 and the second cover plate 20 can be relatively small. Since the overall size of the cover mechanism 100 is the sum of the sizes of the first cover plate 10 and the second cover plate 20, when overlapping, the overlapping portion accounts for a larger portion of the overall size of the cover mechanism 100, thereby significantly reducing the opening height. The size design of the first cover plate 10 and the second cover plate 20 can improve the ease of sliding overlap and operation, so that the size of the cover mechanism 100 can be effectively reduced after sliding overlap.

[0150] like Figure 12 As shown, in some embodiments of the present application, the length dimension of the cover mechanism 100 when unfolded is H3, the length dimension of the box 201 is H4, the width dimension of the cover mechanism 100 is H5, and the width dimension of the box 201 is H6, and H3, H4, H5, and H6 satisfy: 0.5≤H3 / H4≤1, 0.7≤H5 / H6≤1.

[0151] If H3 / H4 is less than 0.5 and H5 / H6 is less than 0.7, the cover mechanism 100 as a whole will be too small. Since the size of the opening 202 on the box body 201 should be as large as possible to facilitate the insertion of clothes, the smaller cover mechanism 100 cannot completely cover the opening 202, resulting in water splashing when the opening 202 is closed, causing safety problems.

[0152] If H3 / H4 is greater than 1 and H5 / H6 is greater than 1, the cover mechanism 100 as a whole will exceed the size of the cabinet, resulting in an increase in the overall size of the pulsator washing machine 200, which is not conducive to the user's layout of the pulsator washing machine 200.

[0153] When 0.5 ≤ H3 / H4 ≤ 1 and 0.7 ≤ H5 / H6 ≤ 1 in the present application, the cover mechanism 100 can completely block and seal the opening 202 without increasing the overall size of the pulsator washing machine 200. The overall size design of the cover mechanism 100 can be coordinated with the design of the housing 201 and the opening 202, thereby improving the security of the blockage of the opening 202 and serving as an exterior component to enhance the aesthetics of the pulsator washing machine 200.

[0154] The pulsator washing machine 200 provided in the present application includes a housing 201 and a cover mechanism 100. An opening 202 is formed on the top of the housing 201. The cover mechanism 100 is rotatably arranged on the housing 201. The cover mechanism 100 is configured to open or close the opening 202. The cover mechanism 100 includes at least two covers, and the at least two covers are slidably connected. The at least two covers are configured to slide and unfold to cover the opening when closing the opening, and to slide and overlap to store part of the cover when opening the opening.

[0155] When the opening 202 is opened, the cover can be slid and overlapped, so that part of the height of the cover is stored, saving space. When it is fully opened, the space occupied by the cover on the upper part of the pulsator washing machine 200 becomes smaller, thereby reducing the requirement for the opening height, facilitating the layout of the pulsator washing machine 200, and improving the user experience.

[0156] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them.
