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 cover of a conventional pulsator washing machine usually occupies the upper space of the pulsator washing machine when opened, making it inconvenient to take clothes in and out, and resulting in a poor user experience. Utility Model Content

[0004] The embodiment of the present application provides a pulsator washing machine, which can achieve that the door cover does not occupy the upper space of the pulsator washing machine, making it convenient to take and put clothes, and improving user experience.

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

[0006] The chassis has a top surface and a plurality of side walls, wherein the plurality of side walls are arranged around the top surface; an opening is formed on the top surface, and the opening is connected to the interior of the chassis;

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

[0008] The cover mechanism comprises:

[0009] a cover plate, arranged on the top surface;

[0010] Hinge assembly, comprising:

[0011] A connecting member, wherein the axis of the connecting member is parallel to the top surface; the connecting member has a first end and a second end on the axis, the first end being rotatably mounted on the top surface so that the connecting member can rotate relative to the top surface; the first end is disposed near one of the side walls, and the second end is connected to the cover plate by a ball hinge;

[0012] The cover is configured to switch between the covering position and the opening position when the cover rotates relative to the connecting member, through the rotation of the connecting member relative to the top surface;

[0013] When the cover is in the covering position, the cover is arranged on the opening to close the opening; when the cover is in the opening position, the cover is flipped to the side with the top surface facing the side wall and facing one of the side walls.

[0014] In this way, the connection of the connecting member to the cover plate facilitates the rotation of the cover plate to open or close the opening through the ball joint connection of the connecting member and the cover plate. The rotation connection of the connecting member and the chassis, in conjunction with the ball joint connection, allows the cover plate to be moved away from the chassis. The ball joint connection of the connecting member and the cover plate also allows the cover plate to be flipped. The user can switch the cover plate between the covering position and the open position through the first and second ends of the connecting member. When opening, the cover plate rotates to face one side wall of the chassis. When the cover plate is in the open position, it does not occupy the upper space of the pulsator washing machine. The space above the chassis is unobstructed. When the user takes clothes in and out, they are no longer affected by the cover plate, making it convenient to take clothes in and out, thereby improving the user experience.

[0015] In some embodiments of the present application, the connecting member is configured such that when the connecting member rotates relative to the top surface, the second end has a first position and a second position relative to the top surface;

[0016] The second end is located on the top surface when in the first position;

[0017] The second end extends along the top surface toward one of the side walls when in the second position;

[0018] When the cover is in the covering position, the second end is located at the first position; when the cover is in the opening position, the second end is located at the second position.

[0019] In this way, when the cover is switched from the covering position to the open position, the second end can be moved from the first position located on the top surface to the second position extending along the top surface toward one of the side walls, that is, away from the top surface, by rotating the connecting piece relative to the top surface, thereby facilitating the cover to be switched to the open position by flipping when in the second position without interfering with the top surface or the side wall.

[0020] In some embodiments of the present application, the rotation axis of the first end is perpendicular to the top surface.

[0021] In this way, by setting the rotation axis of the first end to be perpendicular to the top surface, it is convenient to rotate the second end of the connecting member on the plane where the top surface is located, thereby switching between the first position and the second position. At the same time, it can also prevent the problem of collision and interference between the connecting member and the top surface when the second end of the connecting member is rotated to be located on the top surface.

[0022] In some embodiments of the present application, the hinge assembly further includes:

[0023] A hinge shaft and a sleeve, one of the hinge shaft and the sleeve is vertically mounted on the top surface, and the other is connected to the first end;

[0024] The sleeve is sleeved on the hinge shaft, and the center line of the hinge shaft or the sleeve installed on the top surface forms the rotation axis of the first end.

[0025] In this way, by setting the hinge shaft and the sleeve, the connecting member and the chassis can be rotatably connected, so that the second end of the connecting member is away from the chassis, which is convenient for the cover to flip over. The structure is simple and easy to process and install.

[0026] In some embodiments of the present application, the hinge assembly further includes:

[0027] A ball seat portion and a ball head portion, wherein one of the ball seat portion and the ball head portion is provided on the cover plate, and the other is provided on the second end;

[0028] The ball seat portion is provided with a spherical groove, and the ball head portion is arranged in the spherical groove.

[0029] In this way, the ball-joint connection allows the second end of the connector and the cover to move and rotate freely in three dimensions. For example, the cover can be rotated vertically to flip it over. The cover can also be rotated horizontally, cooperating with the rotating connector to move the cover relative to the chassis. This allows the cover to move freely in all directions and flip it relative to the chassis. The arrangement of the ball seat and ball head realizes the ball-joint connection between the connector and the cover, which has a simple structure and is easy to manufacture and install.

[0030] In some embodiments of the present application, the ball seat portion or the ball head portion is provided on one side edge of the cover plate.

[0031] In this way, the ball seat or ball head is arranged at the edge of the cover plate, so that when the cover plate is turned over, most of the cover plate is located below the ball seat under the cooperation of the ball head and the ball seat, so that the cover plate does not occupy the upper space of the opening.

[0032] In some embodiments of the present application, when the cover is in the open position:

[0033] A side wall opposite to the cover plate has a concave surface that is concave toward the interior of the chassis, and along the width direction of the chassis, the concave surface is opposite to the cover plate;

[0034] The recessed surface is configured to accommodate a portion of the cover plate when the cover plate switches from the covering position to the opening position.

[0035] In this way, by providing a recessed surface toward the interior of the chassis on the side wall opposite to the cover when in the open position, part of the cover can be accommodated, thereby reducing the size occupied by the cover in the width direction of the chassis when in the open position, and making the appearance of the washing machine neater in the open position, thereby improving the aesthetics.

[0036] In some embodiments of the present application, the plurality of side walls include a left side wall and a right side wall, and along the width direction of the chassis, the left side wall and the right side wall are opposite to each other;

[0037] When the cover is in the open position, it is opposite to the left wall or the right wall.

[0038] In this way, setting the open position of the cover to be opposite to the left wall or the right wall can facilitate user operation. Since the user usually stands in front of the chassis, setting the open position of the cover to be opposite to the left wall or the right wall can allow the user to switch the cover between the covering position and the open position without moving.

[0039] In some embodiments of the present application, an anti-collision member is provided on the side wall opposite to the cover in the open position.

[0040] In this way, the anti-collision member is used to support the cover plate when it is turned over, thereby limiting the turning position of the cover plate, that is, stopping the cover plate in the open position to prevent the cover plate from colliding with the side wall of the chassis.

[0041] In a second aspect, an embodiment of the present application provides a pulsator washing machine, comprising:

[0042] The chassis has a top surface and a plurality of side walls, wherein the plurality of side walls are arranged around the top surface; an opening is formed on the top surface, and the opening is connected to the interior of the chassis;

[0043] The drum assembly has a washing cavity, which is connected to the drum opening of the drum assembly; the drum assembly is arranged in the chassis, and the drum opening of the drum assembly faces the opening;

[0044] The cover mechanism comprises:

[0045] a cover plate, arranged on the top surface;

[0046] A hinge assembly, one end of which is rotatably connected to the top surface and is disposed near one of the side walls so that the hinge assembly can rotate relative to the top surface; the other end of the hinge assembly is connected to the cover plate by a ball joint;

[0047] The cover is configured to switch between a covering position and an open position when the cover rotates relative to the hinge assembly, through the rotation of the hinge assembly relative to the top surface;

[0048] When the cover is in the covering position, the cover is arranged on the opening to close the opening; when the cover is in the opening position, the cover is flipped to the side with the top surface facing the side wall and facing one of the side walls.

[0049] In this way, after the opening is opened, the cover is moved away from the chassis by the hinge assembly, and the cover is rotated after movement to turn the cover to the bottom of the top of the chassis, thereby switching the cover between the covering position and the open position. When opening, the cover is turned to be opposite to one side wall of the chassis. When the cover is in the open position, the cover does not occupy the upper space of the pulsator washing machine, and the space above the chassis is unobstructed. When the user takes and puts clothes, he is no longer affected by the cover, which makes taking and putting convenient and improves the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0070] 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.

[0071] The covers of conventional pulsator washing machines all open upwards. After opening, the covers face upwards. Therefore, a certain opening height needs to be set. In addition, the covers occupy the upper space of the pulsator washing machine, which is inconvenient for taking and placing clothes, and the user experience is poor.

[0072] After repeated thinking and verification, the inventor found that if a hinge assembly or connector is used to connect the cover of the pulsator washing machine to the top surface of the chassis, after opening, the cover can be folded to the side of the pulsator washing machine by rotating it, so that the cover no longer occupies the upper space of the pulsator washing machine. The space above the top opening of the chassis is unobstructed, and users are no longer affected by the cover when taking and putting clothes, which makes taking and putting convenient and improves the user experience.

[0073] 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. Figure 3 This is the third structural schematic diagram of the pulsator washing machine provided in an embodiment of the present application. Figure 4 This is the fourth structural schematic diagram of the pulsator washing machine provided in an embodiment of the present application. Figure 5 This is the fifth structural schematic diagram of the pulsator washing machine provided in an embodiment of the present application.

[0074] like Figure 1 and Figure 2 As shown, a pulsator washing machine 200 provided in an embodiment of the present application includes a chassis 201. Chassis 201 has a top surface 203 and a plurality of side walls, which are disposed around top surface 203. Top surface 203 is formed with an opening 202. Opening 202 communicates with the interior of chassis 201. Opening 202 is used for users to insert clothes and detergent.

[0075] The width of the washing machine is the first direction x, i.e., the direction from the left side wall to the right side wall of the washing machine. The length of the washing machine is the second direction y, i.e., the direction from the front side wall to the rear side wall of the washing machine. The vertical direction of the washing machine is the third direction z, i.e., the direction perpendicular to the first direction x and the second direction y. The top surface 203 of the washing machine is located at one edge of the washing machine in the third direction z.

[0076] The pulsator washing machine 200 provided in the embodiment of the present application further includes a cover mechanism 100. The cover mechanism 100 is provided on the chassis 201 and is used to open or close the opening 202.

[0077] 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.

[0078] The pulsator washing machine 200 in the present application further comprises a motor. The motor is arranged in the chassis 201 and is connected to the inner tub to drive the inner tub to rotate.

[0079] The cover mechanism 100 includes a cover 10. The cover 10 is disposed on a top surface 203 and has a covering position and an open position. In the covering position, the cover 10 covers the opening 202, thereby sealing the opening 202. In the open position, the cover 10 is flipped so that the top surface 203 faces the side wall and faces one of the side walls, thereby opening the opening 202.

[0080] By setting the cover 10 in the open position to be opposite to the side wall of the pulsator washing machine, the cover 10 no longer occupies the upper space of the pulsator washing machine, and the space above the top opening 202 of the chassis is unobstructed. When users take and put clothes, they are no longer affected by the cover 10, which makes taking and putting clothes convenient and improves the user experience.

[0081] The cover mechanism 100 further includes a hinge assembly 20. The hinge assembly 20 connects the cover 10 and the chassis 201. The hinge assembly 20 is configured to switch the cover 10 between an open position and a covering position.

[0082] One end of the hinge assembly 20 is rotatably connected to the top surface 203 and is disposed near one of the side walls so that the hinge assembly 20 can rotate relative to the top surface 203. The other end of the hinge assembly 20 is connected to the cover plate 10 by a ball joint.

[0083] The cover plate 10 is configured to be able to switch between the covering position and the opening position when the cover plate 10 rotates relative to the hinge assembly 20 , through the rotation of the hinge assembly 20 relative to the top surface 203 .

[0084] like Figure 1 As shown, in the covering position, the cover 10 rotates relative to the chassis 201 via the hinge assembly 20 so that the cover 10 covers the opening 202 , thereby blocking and closing the opening 202 .

[0085] like Figure 2 As shown, when opening the opening 202 , the cover 10 rotates upward relative to the chassis 201 via the hinge assembly 20 , so that the cover 10 as a whole rotates to the side above the opening 202 and away from the opening 202 , thereby opening the opening 202 .

[0086] like Figure 3 As shown, in Figure 2 On the basis of opening the opening 202 , the hinge assembly 20 can rotate relative to the chassis 201 , so that the cover 10 moves relative to the chassis 201 through the hinge assembly 20 , thereby moving the cover 10 away from the chassis 201 .

[0087] like Figure 4 As shown, when the cover 10 moves away from the edge of one side of the chassis 201, or when the cover 10 moves to the farthest distance from the chassis 201 through the hinge assembly 20, the relative movement of the cover 10 stops.

[0088] like Figure 5 As shown, the cover 10 is connected to the chassis 201 through the hinge assembly 20, so that the cover 10 Figure 4 On the basis away from chassis 201, flip to a side of top surface 203 towards sidewall, and relative with one of sidewall.At this moment, cover plate 10 is positioned at the open position below chassis 201 tops, promptly cover plate 10 is positioned at the next to chassis 201 side edges.

[0089] After opening the opening 202, the cover 10 is moved away from the chassis 201 by the hinge assembly 20, and the cover 10 is rotated after the movement to move it to the bottom of the top of the chassis 201, so that the cover 10 no longer occupies the upper space of the pulsator washing machine 200. The space above the top opening of the chassis 201 is unobstructed, and the user is no longer affected by the cover 10 when taking and putting clothes, which makes taking and putting convenient and improves the user experience.

[0090] Relative to rotating the cover 10 along a vertical axis on the top surface 203 in a horizontal plane away from the top surface 203 to open the opening 202, until the side edge of the cover 10 close to the chassis 201 is parallel to the edge of the top surface close to the cover 10, at this time the cover 10 opens the opening 202, it is necessary to reserve an area of ​​at least one cover 10 next to one side of the chassis 201. The layout of the washing machine is affected by this and requires a larger area. Then, the cover 10 away from the top surface 203 is flipped downward in the vertical direction, so that the cover 10 is opened relative to the side wall. The embodiment of the present application first rotates the cover 10 above the opening 202 to open without occupying the area next to the chassis 201. Subsequently, the cover 10 is moved a certain distance in the width direction of the chassis 201. At this time, since the cover 10 is in a vertical state, it will only occupy a small area next to the chassis 201 when moving. The cover 10 is flipped so that it is in an open position relative to the side wall. During the flipping process, the area occupied by the cover 10 next to the chassis 201 remains almost unchanged. This will result in a smaller area being passed through when switching from the covering position to the open position on the horizontal plane where the top surface 203 is located, thereby reducing the area required to be reserved for the washing machine and the demand for horizontal space layout for the washing machine, making it easier for users to choose an installation location in the house. In addition, when in the open position, there is no obstruction above the opening 202 of the chassis 201, making it convenient to take clothes in and out.

[0091] In some embodiments of the present application, the cover mechanism 100 is disposed on the top of the chassis 201 and is rotatably disposed to the left of the opening 202, thereby facilitating user operation by flipping the cover 10 to the left side of the pulsator washing machine 200 for conveniently placing and removing clothes and rotating the cover 10. However, the present invention is not limited thereto, and in some other embodiments of the present application, the cover mechanism 100 may also be rotatably disposed to the right, rear, or even front of the opening 202.

[0092] In some embodiments of the present application, the multiple side walls include a left side wall and a right side wall, and along the width direction of the chassis 201, the left side wall and the right side wall are opposite to each other.

[0093] When the cover 10 is in the open position, it is opposite to the left wall or the right wall.

[0094] If the open position of the cover 10 is set to be opposite to the rear side wall, the user needs to be as close to the front side wall of the chassis 201 as possible, which makes it inconvenient to open the cover 10. Moreover, when the cover 10 is rotated, the required size along the width direction of the chassis 201 becomes larger, which is not conducive to the layout of the washing machine. At the same time, the water inlet of most washing machines is set on the rear side, and there will be interference when the open position of the cover 10 is opposite to the rear side wall.

[0095] If the opening position of the cover 10 is set to be opposite to the front side wall, when the user opens the cover 10, the opening 202 will still be vertically blocked, and the user needs to flip it over before operating the opening 202, which is extremely inconvenient. Moreover, when the cover 10 is rotated, the required size along the width direction of the chassis 201 becomes larger, which is not conducive to the layout of the washing machine.

[0096] In contrast, in the embodiment of the present application, the open position of the cover 10 is set to be opposite to the left side wall or the right side wall, which can facilitate user operation. Since the user usually stands in front of the chassis 201, the open position of the cover 10 is set to be opposite to the left side wall or the right side wall, the user can switch the cover 10 between the covering position and the open position without moving.

[0097] The following text Figure 5 Taking the example of the cover 10 being opened and facing the left side wall as shown in the figure, the structure of the pulsator washing machine is further described.

[0098] See also Figure 4 and Figure 5 As shown, in some embodiments of the present application, when the cover 10 is in the open position: the side wall opposite to the cover 10 has a recessed surface 204 recessed toward the interior of the chassis 201 , and along the width direction of the chassis 201 , the recessed surface 204 is opposite to the cover 10 .

[0099] The recessed surface 204 is configured to accommodate a portion of the cover plate 10 when the cover plate 10 is switched from the covering position to the opening position.

[0100] By providing a recessed surface 204 recessed toward the interior of the chassis 201 on the side wall opposite to the cover 10 when in the open position, a portion of the cover 10 can be accommodated, thereby reducing the size occupied by the cover 10 in the width direction of the chassis 201 when in the open position, and making the appearance of the washing machine in the open position neater and improving the aesthetics.

[0101] Figure 6 for Figure 2 The exploded structure diagram of the cover mechanism of the pulsator washing machine is shown. Figure 7 for Figure 6 Schematic diagram of the structure of the cover plate of the cover plate mechanism shown. Figure 8 for Figure 6 Schematic diagram of the structure of the hinge assembly of the cover mechanism shown. Figure 9 for Figure 6 The schematic diagram of the structure of the chassis of the pulsator washing machine is shown.

[0102] like Figure 6As shown, in some embodiments of the present application, the hinge assembly 20 includes a connector 21, the axis of which is parallel to the top surface 203. The connector 21 has a first end 211 and a second end 212 on the axis. The first end 211 of the connector 21 is rotatably mounted on the top surface 203, allowing the connector 21 to rotate relative to the top surface 203. The second end of the connector 21 is connected to the cover plate 10 by a ball joint. The first end 211 is positioned near one of the side walls.

[0103] The cover plate 10 is configured to be able to switch between the covering position and the opening position when the cover plate 10 rotates relative to the connecting member 21 , through the rotation of the connecting member 21 relative to the top surface 203 .

[0104] The connection member 21 rotates relative to the top surface 203, which means that the connection member 21 rotates relatively around a fixed axis on the top surface 203 of the chassis 201. This connection method limits the connection member 21 to rotate in one direction and cannot move or rotate in other directions.

[0105] The ball-joint connection between connector 21 and cover 10 allows connector 21 and cover 10 to move and rotate freely in three dimensions. Also known as a universal joint, this is a more flexible connection method, allowing the connection point to rotate in any direction, thus achieving full freedom of movement.

[0106] Through the setting of the connecting member 21, it is convenient to connect the connecting member 21 to the cover plate 10 through the ball hinge, so that the cover plate 10 can be rotated to open or close the opening 202. The connecting member 21 is connected to the chassis 201 through rotation, and the ball hinge connection is used to realize the cover plate 10 away from the chassis 201. The ball hinge connection between the connecting member 21 and the cover plate 10 can also realize the flipping of the cover plate 10, thereby moving the cover plate 10 away from the top of the chassis 201.

[0107] The connecting member 21 is configured such that when it rotates relative to the top surface 203 , the second end 212 has a first position and a second position relative to the top surface 203 .

[0108] like Figure 2 As shown, the second end 212 is located on the top surface 203 in the first position.

[0109] like Figure 4 and Figure 5 As shown, the second end 212 extends along the top surface 203 toward one of the side walls when in the second position.

[0110] When the cover 10 is in the covering position, the second end 212 is located at the first position. When the cover 10 is in the opening position, the second end 212 is located at the second position.

[0111] When the cover 10 is switched from the covering position to the open position, the second end 212 can be moved from the first position on the top surface 203 to the second position extending along the top surface 203 toward one of the side walls, that is, away from the top surface 203, by rotating the connecting member 21 relative to the top surface 203. This makes it easier for the cover 10 to switch to the open position by flipping when in the second position without interfering with the top surface 203 or the side walls.

[0112] like Figure 4 As shown, when the second end 212 of the connector 21 is in the second position, the angle between the connector 21 and the edge of the chassis 201 close to the connector 21 is 90°. At this time, the distance between the cover 10 and the chassis 201 is the farthest.

[0113] In some embodiments of the present application, the rotation axis of the first end 211 is perpendicular to the top surface 203 .

[0114] By setting the rotation axis of the first end 211 to be perpendicular to the top surface 203, it is convenient to rotate the second end 212 of the connecting member 21 on the plane where the top surface 203 is located, thereby switching between the first position and the second position. At the same time, it can also prevent the problem of collision and interference between the connecting member 21 and the top surface 203 when the second end 212 of the connecting member 21 is rotated to be located on the top surface 203.

[0115] like Figure 8 and Figure 9 As shown, in some embodiments of the present application, the hinge assembly 20 further includes a hinge shaft 22 and a sleeve 23 .

[0116] One of the hinge shaft 22 and the sleeve 23 is vertically mounted on the top surface 203 , and the other is connected to the first end 211 .

[0117] The sleeve 23 is sleeved on the hinge shaft 22 , and the center line of the hinge shaft 22 or the sleeve 23 installed on the top surface 203 forms the rotation axis of the first end 211 .

[0118] For example, Figure 8 The figure shows that the hinge shaft 22 is mounted vertically on the top surface 203, while the sleeve 23 is connected to the first end 211. The sleeve 23 can rotate along the centerline of the hinge shaft 22. In some examples, the hinge shaft 22 can also be installed on the first end 211 of the connecting member 21, and the sleeve 23 can be installed on the top surface 203 of the chassis 201. The hinge shaft 22 is inserted into the groove of the sleeve 23, so that the other parts of the connecting member 21 are located outside the sleeve 23. The hinge shaft 22 can rotate within the sleeve 23, thereby driving the other parts of the connecting member 21 to rotate about the centerline of the sleeve 23.

[0119] By setting the hinge shaft 22 and the sleeve 23, the connecting member 21 can be rotatably connected to the chassis 201, so that the second end 212 of the connecting member 21 is away from the chassis 201, which is convenient for turning over the cover 10. The structure is simple and easy to process and install.

[0120] In some embodiments of the present application, the hinge shaft 22 is provided on the top surface 203 of the chassis 201. The first end 211 of the connector 21 is provided with a sleeve 23. The sleeve 23 is sleeved on the hinge shaft 22, thereby rotatably connecting the connector 21 to the top surface 203 of the chassis 201.

[0121] Specifically, the sleeve 23 can rotate on the hinge shaft 22 , thereby causing the connecting member 21 to rotate around the hinge shaft 22 .

[0122] like Figure 9 As shown, in some embodiments of the present application, the hinge shaft 22 is disposed at the top of the chassis 201 and is disposed close to the opening 202 .

[0123] By arranging the hinge shaft 22 beside the opening 202 , when the cover 10 moves relative to the chassis 201 via the connecting member 21 , the cover 10 can be moved away from the chassis 201 by rotating the connecting member 21 on the chassis 201 .

[0124] In other embodiments of the present application, the hinge shaft 22 can also be arranged at the top of the side wall of the chassis 201, so as to further reduce the height occupation.

[0125] In some embodiments of the present application, a limit member may be further provided on the chassis 201, and the limit member is provided on both sides of the rotation trajectory of the connecting member 21, so as to stop the rotation of the connecting member 21 and restrict the connecting member 21 from rotating between the rotation trajectories, thereby realizing the rotation of the second end 212 of the connecting member 21 between the first position and the second position.

[0126] The limiter can prevent the connector 21 from excessively rotating relative to the chassis 201, thereby improving operational convenience and preventing the cover 10 from colliding with other components, such as the side wall of the chassis 201, and causing damage during movement relative to the chassis 201.

[0127] Optionally, a limiting member is provided at the top of the chassis 201 , and two limiting members are provided, and the two limiting members are respectively provided on both sides of the rotation direction of the connecting member 21 , thereby limiting the rotation of the connecting member 21 from both sides.

[0128] like Figure 7 and Figure 8 As shown, in some embodiments of the present application, the hinge assembly 20 further includes a ball seat portion 24 and a ball head portion 25 , one of the ball seat portion 24 and the ball head portion 25 is disposed on the cover plate 10 , and the other is disposed at the second end 212 .

[0129] The ball seat portion 24 has a spherical groove therein, and the ball head portion 25 is disposed in the spherical groove.

[0130] The ball joint connection allows the second end 212 of the connector 21 and the cover 10 to move and rotate freely in three dimensions, such as allowing the cover 10 to rotate in the vertical direction, thereby flipping the cover 10, and also allowing the cover 10 to rotate in the horizontal direction, thereby cooperating with the rotating connector 21 to move the cover 10 relative to the chassis 201, thereby realizing the cover 10's full range of movement freedom, allowing the cover 10 to flip relative to the chassis 201.

[0131] By disposing the ball seat portion 24 and the ball head portion 25 , a ball hinge connection between the connector 21 and the cover plate 10 is achieved, which has a simple structure and is easy to process and install.

[0132] In some embodiments of the present application, the ball seat portion 24 is provided on the cover plate 10. The first end of the connector 21 is provided with a ball head portion 25. The ball head portion 25 is provided in the ball seat portion 24, so that the second end 212 of the connector 21 is connected to the cover plate 10 in a spherical hinge.

[0133] like Figure 7 As shown, in some embodiments of the present application, the ball seat portion 24 or the ball head portion 25 is provided on an edge of one side of the cover plate 10 .

[0134] The ball seat portion 24 or the ball head portion 25 is arranged at the edge of the cover plate 10 so that when the cover plate 10 is flipped over with the cooperation of the ball head portion 25 and the ball seat portion 24, most of the cover plate 10 is located below the ball seat portion 24, so that the cover plate 10 does not occupy the upper space of the opening 202.

[0135] In some embodiments of the present application, the ball seat portion 24 or the ball head portion 25 is arranged in the middle of one side edge of the cover plate 10, so as to reduce the length of the cover plate 10 protruding from the side wall of the chassis 201 after the cover plate 10 is flipped over, thereby improving safety and aesthetics.

[0136] In some embodiments of the present application, the ball seat portion 24 is fixed to the cover plate 10 by screws or other fixing members, but is not limited thereto. The ball seat portion 24 can also be integrally formed on the cover plate 10 .

[0137] In other embodiments of the present application, the ball head 25 may be provided on the cover plate 10 , and the second end of the connector 21 may be provided with a ball seat 24 , in which the ball head 25 is provided.

[0138] By providing a ball seat portion 24 on the connecting member 21 and a ball head portion 25 on the cover plate 10 , a spherical joint connection between the connecting member 21 and the cover plate 10 can also be achieved.

[0139] It should be noted that the length of the connecting member 21 should be as short as possible to prevent the cover 10 from moving too far relative to the chassis 201 through the connecting member 21, thereby causing the horizontal dimension to be occupied.

[0140] In some other embodiments of the present application, the first end 211 of the connecting member 21 is connected to the chassis 201 by a ball hinge, and the second end 212 of the connecting member 21 is connected to the cover plate 10 by a ball hinge.

[0141] By arranging ball hinge structures at both ends of the connecting member 21, on the one hand, the cover 10 in the above embodiment can be rotated to open or close the opening, the cover 10 can be moved away from the chassis 201, and the cover 10 can be flipped. On the other hand, the ball hinge connection between the connecting member 21 and the chassis 201 can also enable the cover 10 to move up and down slightly after flipping, thereby facilitating user operation and adjustment.

[0142] In some embodiments of the present application, the hinge assembly 20 also includes two ball sockets 24 and a ball head 25, one of the ball sockets 24 is arranged on the cover 10, and the other ball socket 24 is arranged on the chassis 201, and ball heads 25 are respectively provided at both ends of the connecting member 21, and the ball heads 25 are respectively arranged in the corresponding ball sockets 24.

[0143] In other embodiments of the present application, the hinge assembly 20 also includes two ball seat portions 24 and a ball head portion 25, one of the ball head portions 25 is arranged on the cover plate 10, and the other ball head portion 25 is arranged on the chassis 201, and the ball seat portions 24 are respectively provided at both ends of the connecting member 21, and the ball head portions 25 are respectively provided in the corresponding ball seat portions 24.

[0144] In some embodiments of the present application, the pulsator washing machine 200 is further provided with an anti-collision member, which is provided on the side wall of the chassis 201 and is located between the open position of the cover 10 and the chassis 201. That is, the anti-collision member is provided on the side wall opposite to the open position of the cover 10.

[0145] The anti-collision member is used to support the cover plate 10 when the cover plate 10 is turned over, thereby limiting the turning position of the cover plate 10, that is, stopping the cover plate 10 at the open position to prevent the cover plate 10 from colliding with the side wall of the chassis 201.

[0146] In some embodiments of the present application, the connector 21 may be composed of multiple sub-connectors that are movably connected to each other, thereby improving the operability of the cover 10. For example, the multiple sub-connectors can be rotatably connected in the horizontal direction, or the multiple sub-connectors can be relatively slidably connected to each other, thereby reducing the overall length of the connector 21.

[0147] Figure 10 for Figure 1 The diagram shows the dimensions and structure of a pulsator washing machine.

[0148] like Figure 10As shown, in some embodiments of the present application, the length dimension of the cover plate 10 is H1, the length dimension of the chassis 201 is H2, the width dimension of the cover plate 10 is H3, and the width dimension of the chassis 201 is H4. H1, H2, H3, and H4 satisfy:

[0149] In some embodiments of the present application, 0.5≤H1 / H2≤1,

[0150] In some embodiments of the present application, 0.7≤H3 / H4≤1.3.

[0151] If H1 / H2 is less than 0.5 and H3 / H4 is less than 0.7, the cover 10 as a whole will be too small. Since the size of the opening 202 on the chassis 201 should be as large as possible to facilitate the insertion of clothes, the smaller cover 10 cannot completely cover the opening 202, causing water to splash when the opening 202 is closed, causing safety problems.

[0152] If H1 / H2 is greater than 1 and H3 / H4 is greater than 1.3, the cover 10 as a whole will exceed the size of the chassis 201, 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] In contrast, in the present application, when 0.5 ≤ H1 / H2 ≤ 1 and 0.7 ≤ H3 / H4 ≤ 1.3, the cover 10 can completely block and seal the opening 202 without increasing the overall size of the pulsator washing machine 200. The size design of the cover 10 can be coordinated with the design of the chassis 201 and the opening 202, blocking the opening 202 for safety and serving as an exterior component to enhance the aesthetics of the pulsator washing machine 200.

[0154] In some embodiments of the present application, a handle may be further provided on the cover plate 10. The handle is used for a user to hold so as to facilitate relative movement and rotation of the cover plate 10.

[0155] The handle can be a convex block protruding from the cover plate 10, or a groove formed on the cover plate 10. Preferably, the handle is a groove on the cover plate 10, thereby reducing the occupation of the horizontal direction when flipping.

[0156] The pulsator washing machine 200 provided in the present application includes a chassis 201 and a cover mechanism 100. An opening 202 is formed at the top of the chassis 201. The cover mechanism 100 is configured to open or close the opening 202. The cover mechanism 100 includes a cover 10 and a hinge assembly 20. The hinge assembly 20 connects the cover 10 to the chassis 201. The cover 10 has a covering position and an open position. When the cover 10 is in the covering position, it covers the opening 202. When the cover 10 is in the open position, it opens the opening 202. The hinge assembly 20 is configured to switch the cover 10 between the open position and the covering position. The hinge assembly 20 is configured to rotate the cover 10 relative to the chassis 201 in the covering position to open the opening 202, move the cover 10 away from the chassis 201 after opening the opening 202, and rotate the cover 10 to move it to the open position below the top of the chassis 201.

[0157] After opening the opening 202, the cover 10 can be moved away from the chassis 201 by the hinge assembly 20, and the cover 10 can be rotated after moving to the bottom of the top of the chassis 201, so that the cover 10 no longer occupies the upper space of the pulsator washing machine 200. The space above the opening 202 at the top of the chassis 201 is unobstructed, and the user is no longer affected by the cover 10 when taking and putting clothes, which makes taking and putting convenient and improves the user experience.
