Abstract
Description
Technical Field
[0001] Some embodiments of the present application relate to washing equipment technology, and more particularly to a washing machine. Background Art
[0002] A washing machine is a cleaning appliance that uses electrical energy to generate mechanical action to wash clothes.
[0003] In related art, a washing machine typically comprises a housing and a drum assembly. The drum assembly is located within the housing and comprises an outer drum and an inner drum, with the inner drum defining a washing chamber. By increasing the size of the housing, the volume of the drum assembly can be increased, thereby increasing the maximum capacity of the washing machine's drum assembly, thereby meeting the demand for larger washing capacity.
[0004] However, as the size of the cabinet increases, more materials are used for the cabinet, resulting in high production costs for the washing machine. Utility Model Content
[0005] The purpose of this application is to at least solve the above-mentioned problems.
[0006] Some embodiments of the present application provide a washing machine, comprising:
[0007] A chassis, comprising:
[0008] A box body, wherein the box body has two first walls disposed opposite to each other in the width direction of the washing machine, and an upper edge and a lower edge disposed opposite to each other in the height direction of the washing machine;
[0009] A frame is provided on the box body and has a loading port;
[0010] A barrel assembly is provided in the box body, the barrel assembly has a washing cavity, the barrel opening of the barrel assembly faces the delivery port, and the barrel opening of the barrel assembly is connected to the washing cavity and faces the delivery port; the barrel assembly includes:
[0011] outer cylinder;
[0012] An inner cylinder rotatably disposed in the outer cylinder;
[0013] A door cover is rotatably connected to the chassis, and the door cover can open or close the delivery port when rotating relative to the chassis;
[0014] A first concave-convex structure is provided on at least one of the first walls at a position corresponding to the barrel assembly;
[0015] The first concave-convex structure is a first concave structure on the side of the first wall facing the outer drum, and the first concave structure is used to avoid the drum assembly; the first concave-convex structure is a first convex structure on the side of the first wall facing away from the outer drum; in the depth direction of the washing machine, the first convex structure has a first edge and a second edge that are oppositely arranged;
[0016] In the height direction of the washing machine, the distance between the first concave-convex structure and the upper edge is D1, and D1 is greater than 5 mm;
[0017] In the height direction of the washing machine, the distance between the first concave-convex structure and the lower edge is D2, and D2 is greater than 5mm
[0018] The dimension of the first protrusion structure in the width direction of the washing machine is L1, and L1 is less than 5 mm;
[0019] A distance between the first edge and the second edge in a depth direction of the washing machine is L2, and L2 is greater than 139 mm and less than 537 mm;
[0020] The dimension of the first wall in the depth direction of the washing machine is L3, and the ratio of L2 to L3 is greater than 0.26 and less than 0.55.
[0021] The washing machine provided in some embodiments of the present application is provided with a first concave-convex structure on at least one first wall of the case. The first concave-convex structure is a first concave structure on the side of the first wall facing the outer drum, and the first concave-convex structure is a first convex structure on the side of the first wall away from the outer drum. The first concave structure can avoid the drum assembly, so that when the size of the chassis remains unchanged, the volume of the chassis can be increased, the operating space of the inner drum assembly of the washing machine is increased, and the drum assembly is prevented from colliding with the chassis. At the same time, the volume of the drum assembly is increased, thereby reducing the production cost of the washing machine.
[0022] By providing a first concave-convex structure on at least one first wall of the box body, the rigidity of the box body can be increased, the natural frequency of the box body can be improved, the vibration noise of the washing machine can be improved, and the balance performance of the drum assembly and the transportation performance of the entire machine can be improved.
[0023] If the spacing between the first concave-convex structure and the upper edge is less than 5 mm, the manufacturing difficulty of the mold for forming the first concave-convex structure will increase, thereby increasing the production cost of the washing machine. By increasing the spacing between the first concave-convex structure and the upper edge to greater than 5 mm, the manufacturing difficulty of the mold for forming the first concave-convex structure can be reduced, thereby reducing the production cost of the washing machine.
[0024] If the spacing between the first concave-convex structure and the lower edge is less than 5 mm, the manufacturing difficulty of the mold for forming the first concave-convex structure will increase, thereby increasing the production cost of the washing machine. By increasing the spacing between the first concave-convex structure and the lower edge to greater than 5 mm, the manufacturing difficulty of the mold for forming the first concave-convex structure can be reduced, thereby reducing the production cost of the washing machine.
[0025] If the size of the first protrusion structure is larger than 5 mm, the size of the washing machine packaging will increase, which will increase the transportation cost of the washing machine. However, if the size of the first protrusion structure is less than or equal to 5 mm, the size of the washing machine packaging will not increase, thereby reducing the transportation cost of the washing machine.
[0026] If L2 is less than 139 mm, the housing will be insufficiently strong, causing deformation during operation. If L2 is greater than 537 mm, the first concave-convex structure will be too close to the edge of the first wall, increasing the difficulty of manufacturing the mold for forming the first concave-convex structure. By adjusting the distance between the first and second edges in the depth direction of the washing machine, deformation of the housing during operation can be avoided, while also reducing the difficulty of manufacturing the mold for forming the first concave-convex structure.
[0027] If the ratio of L2 to L3 is less than 0.26, the distance between the first and second edges in the depth direction of the washing machine will be too small, resulting in insufficient strength of the housing and deformation during operation. If the ratio of L2 to L3 is greater than 0.55, the distance between the first and second edges in the depth direction of the washing machine will be too large, placing the first concave-convex structure too close to the edge of the first wall, increasing the difficulty of manufacturing the mold for forming the first concave-convex structure. By limiting the ratio of L2 to L3, deformation of the housing during operation can be avoided and the difficulty of manufacturing the mold for forming the first concave-convex structure can be reduced.
[0028] In some embodiments of the present application, the first concave-convex structure extends along the height direction of the washing machine.
[0029] The above technical solution has the following advantages or beneficial effects: the first recessed structure can be extended along the height direction of the washing machine, so that the drum assembly does not contact the cabinet in the height direction of the washing machine, thereby preventing the drum assembly from hitting the cabinet.
[0030] In some embodiments of the present application, in the depth direction of the washing machine, the first concave-convex structure is symmetrically arranged relative to the axis of the outer drum;
[0031] In the width direction of the washing machine, the distance between the first wall and the outer drum is D3, the distance between the first concave-convex structure and the outer drum is D4, the size of the first concave-convex structure is L4, and D3 satisfies: D3=D4+L4.
[0032] The above technical solution has the following advantages or beneficial effects: When the dimensions of the chassis remain unchanged, the first concave structure of the first concave-convex structure can increase the volume of the chassis, preventing the outer cylinder from colliding with the chassis when the outer cylinder is located away from its axis. When the dimensions of the chassis remain unchanged, the volume of the cylinder assembly can be increased by the space between the first concave-convex structure and the outer cylinder, and by the space in the first concave structure of the first concave-convex structure.
[0033] In some embodiments of the present application, in the depth direction of the washing machine, second concave-convex structures are respectively provided on both sides of the first concave-convex structure, and the second concave-convex structure is spaced apart from the first concave-convex structure;
[0034] The second concave-convex structure is a second concave structure on the side of the first wall facing the interior of the box; the second concave-convex structure is a second convex structure on the side of the first wall facing away from the interior of the box.
[0035] The above technical solution has the following advantages or beneficial effects: by arranging the first concave-convex structure and the second concave-convex structure on the first wall of the box, the rigidity of the box can be increased, the natural frequency of the box can be improved, the vibration noise of the washing machine can be improved, and the balance performance of the drum assembly and the transportation performance of the whole machine can be improved.
[0036] In some embodiments of the present application, in the depth direction of the washing machine, the distance between the second concave-convex structure and the first concave-convex structure is D5, and D5 is greater than 5 mm.
[0037] The above technical solution has the following advantages or beneficial effects: If the spacing between the second concave-convex structure and the first concave-convex structure is less than 5 mm, it will increase the difficulty of manufacturing the mold for forming the first and second concave-convex structures 1112, thereby increasing the production cost of the washing machine. By increasing the spacing between the second concave-convex structure and the first concave-convex structure to greater than 5 mm, the difficulty of manufacturing the mold for forming the first and second concave-convex structures can be reduced, thereby reducing the production cost of the washing machine.
[0038] In some embodiments of the present application, along the depth direction of the washing machine, the housing has two second walls arranged opposite to each other, and an arc angle is formed between the second wall and the first wall;
[0039] In the depth direction of the washing machine, a distance between the second concave-convex structure and the arc corner is D6, and D6 is greater than 25 mm.
[0040] The above technical solution has the following advantages or beneficial effects: if the spacing between the second concave-convex structure and the arc angle is less than 25 mm, the folding knife of the bending machine will have insufficient movement stroke when bending the material forming the box body, thereby preventing the formation of the arc angle between the second wall and the first wall. By ensuring that the spacing between the second concave-convex structure and the arc angle is greater than 25 mm, the folding knife of the bending machine can have sufficient movement stroke when bending the material forming the box body, thereby ensuring the formation of the arc angle between the second wall and the first wall.
[0041] In some embodiments of the present application, the chassis further includes:
[0042] A buckle piece is connected to the second concave-convex structure, and the buckle piece is embedded in the second convex structure.
[0043] The above technical solution has the following advantages or beneficial effects: by embedding the handle in the second protruding structure, the handle is hidden in the chassis, thereby making the washing machine look beautiful as a whole.
[0044] In some embodiments of the present application, the cross-section of the first protrusion structure is trapezoidal.
[0045] The above technical solution has the following advantages or beneficial effects: it can simplify the mold for forming the first concave-convex structure, reducing the difficulty of manufacturing the first concave-convex structure; it can also increase the strength of the first wall, effectively dispersing and transmitting externally applied forces, and reducing stress concentration.

[0067] The following will be combined with the accompanying drawings of some embodiments of the present application to clearly and completely describe the technical solutions of some embodiments of the present application. Obviously, the embodiments described are only some embodiments of the present application, not all embodiments. Based on some embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0068] Some embodiments of the present application provide a washing machine, which may include a pulsator washing machine, a drum washing machine, and other washing equipment capable of washing clothes and objects. Figure 1 To the attached Figure 4 The washing machine is shown as a pulsator washing machine, and the structure of the washing machine is further explained.
[0069] The depth of the washing machine is the X-axis. The width of the washing machine is the Y-axis. The height of the washing machine is the Z-axis. The X-axis, Y-axis, and Z-axis are perpendicular to each other.
[0070] The side of the washing machine in the +X-axis direction is the front side of the washing machine. The side of the washing machine in the -X-axis direction is the rear side of the washing machine. The side of the washing machine in the +Y-axis direction is the left side of the washing machine. The side of the washing machine in the -Y-axis direction is the right side of the washing machine. The side of the washing machine in the +Z-axis direction is the top side of the washing machine. The side of the washing machine in the -Z-axis direction is the bottom side of the washing machine.
[0071] The washing machine includes a cabinet 10 .
[0072] The chassis 10 includes a housing 11. The side of the housing 11 in the +Z axis direction is the top of the housing 11. The side of the housing 11 in the -Z axis direction is the bottom of the housing 11.
[0073] Along the width direction of the washing machine, that is, along the Y-axis direction, the housing 11 has two first walls 111 arranged opposite to each other.
[0074] Along the depth direction of the washing machine, that is, along the X-axis direction, the housing 11 has two second walls 112 that are opposite to each other.
[0075] Along the circumference of the washing machine, an arc-shaped corner 113 is connected between the second wall 112 and the first wall 111. Such an arrangement can make a smooth transition between the second wall 112 and the first wall 111.
[0076] Exemplarily, the material forming the box body 11 is bent by a bending machine, so that an arc angle 113 can be formed between the second wall 112 and the first wall 111 .
[0077] The cabinet 10 includes a frame 12. The frame 12 can be provided on the cabinet body 11. The frame 12 can have a loading port. The loading port is used to load clothes.
[0078] In some examples, the frame 12 is disposed around the top of the box body 11. For example, the frame 12 can be snap-fitted to the box body 11 and fixed by screws.
[0079] The chassis 10 includes a base 16. The base 16 is disposed at the bottom of the box body 11. The base 16 is used to support the box body 11.
[0080] Exemplarily, the base 16 and the box body 11 may be fixed by screws.
[0081] In some embodiments, see Figure 5As shown, the washing machine may further include a drum assembly. The drum assembly is arranged in the housing 11. The drum assembly has a washing chamber. The drum opening of the drum assembly is connected to the washing chamber and faces the loading port so that clothes loaded through the loading port can enter the washing chamber for washing.
[0082] The barrel assembly may include an outer barrel 201. The outer barrel 201 is disposed in the box body 11, and the barrel opening of the outer barrel 201 faces the injection port.
[0083] The drum assembly may include an inner drum 200. The inner drum 200 is rotatably disposed within the outer drum 201, with the opening of the inner drum 200 also facing the inlet. The opening of the inner drum 200 communicates with the washing chamber, thereby connecting the opening of the drum assembly with the washing chamber. The inner drum 200 defines a washing chamber. During the laundry washing process, the inner drum 200 may rotate relative to the outer drum 201 to clean the laundry within the washing chamber.
[0084] The inner tub 200 has a plurality of communication holes on its wall. The communication holes are used to connect the washing chamber with the interior of the outer tub 201 so that the liquid in the washing chamber can flow into the outer tub 201 through the communication holes and be discharged from the outer tub 201 after washing.
[0085] In some embodiments, the washing machine may further include a door cover 40 (see Figure 1 The door cover 40 is rotatably connected to the chassis 10. The door cover 40 can open or close the loading port when rotating relative to the chassis 10.
[0086] For example, a door cover 40 is provided at the top of the cabinet 10 and can open or close the loading port. When the door cover 40 opens the loading port, it is convenient for the user to load clothes into the loading port. When the door cover 40 closes the loading port, it can cover the loading port to enhance the safety of the washing machine during operation.
[0087] In some examples, a first concave-convex structure 1111 is provided on at least one first wall 111 at a position corresponding to the barrel assembly.
[0088] For example, see Figure 5 As shown, in the width direction of the washing machine, the two first walls 111 can be provided with first concave-convex structures 1111 at positions corresponding to the axis of the outer tub 201. The first concave-convex structures 1111 on the two first walls 111 are symmetrically arranged relative to the axis of the outer tub 201.
[0089] In some embodiments, the first wall 111 may be pressed to form a first concave-convex structure 1111 through a mold forming process.
[0090] Among them, see Figures 4 to 7As shown, the first concave-convex structure 1111 is a first concave structure 111a on the side of the first wall 111 facing the outer cylinder 201. The first concave structure 111a is used to avoid the cylinder assembly, that is, the first concave structure 111a can prevent the cylinder assembly from interfering with the box body 11.
[0091] The first concave-convex structure 1111 is a first convex structure 111b on the side of the first wall 111 facing away from the outer drum 201. This arrangement increases the volume of the chassis 10 while maintaining the same size, thereby increasing the operating space of the inner drum assembly of the washing machine and preventing the drum assembly from colliding with the chassis 10. Furthermore, the volume of the drum assembly can be increased, thereby reducing the production cost of the washing machine.
[0092] Exemplarily, first concave-convex structures 1111 are respectively provided on the two first walls 111 at the positions of the corresponding drum assemblies. The first concave-convex structure 1111 is a first concave structure 111a on the side of the first wall 111 facing the outer drum 201, and the first concave-convex structure 1111 is a first convex structure 111b on the side of the first wall 111 away from the outer drum 201, which can increase the volume of the inner drum assembly of the washing machine to 105L and the maximum capacity of the inner drum assembly of the washing machine to 20kg.
[0093] By providing a first concave-convex structure 1111 on at least one first wall 111 of the box body 11, the rigidity of the box body 11 can be increased, the natural frequency of the box body 11 can be improved, the vibration noise of the washing machine can be improved, and the balance performance of the drum assembly and the transportation performance of the entire machine can be improved.
[0094] In some embodiments, the first concave-convex structure 1111 extends along the height direction of the washing machine. In this way, the first concave structure 111a extends along the height direction of the washing machine, so that the drum assembly does not contact the housing 11 in the height direction of the washing machine, thereby preventing the drum assembly from hitting the chassis 10.
[0095] In some examples, the housing 11 may have an upper edge 11a and a lower edge 11b in the height direction of the washing machine (see FIG. Figure 3 The edge at the top of the box body 11 may be an upper edge 11a. The edge at the bottom of the box body 11 may be a lower edge 11b.
[0096] In the height direction of the washing machine, the first concave-convex structure 1111 may be spaced apart from the upper edge 11a by a distance D1 (see Figure 3As shown). Wherein D1 is greater than or equal to 5mm. For example, the value of D1 can be 5mm, 6mm, 7mm, 8mm, 9mm, 10mm or 20mm, etc. Of course, the spacing can also be other numerical values, and those skilled in the art can choose according to needs, and this embodiment does not limit this. If the spacing between the first concave-convex structure 1111 and the upper edge 11a is less than 5mm, the manufacturing difficulty of the mold for forming the first concave-convex structure 1111 will increase, which will increase the production cost of the washing machine. By making the spacing between the first concave-convex structure 1111 and the upper edge 11a greater than or equal to 5mm, the manufacturing difficulty of the mold for forming the first concave-convex structure 1111 can be reduced, thereby reducing the production cost of the washing machine.
[0097] In some examples, in the height direction of the washing machine, the first concave-convex structure 1111 may be spaced apart from the lower edge 11b by a distance D2 (see FIG. Figure 3 As shown). Wherein, D2 is greater than 5mm. For example, the value of D2 can be 5mm, 6mm, 7mm, 8mm, 9mm, 10mm or 20mm, etc. Of course, the spacing can also be other numerical values, and those skilled in the art can choose according to needs, and this embodiment does not limit this. If the spacing between the first concave-convex structure 1111 and the lower edge 11b is less than 5mm, the manufacturing difficulty of the mold for forming the first concave-convex structure 1111 will increase, which will increase the production cost of the washing machine. By making the spacing between the first concave-convex structure 1111 and the lower edge 11b greater than or equal to 5mm, the manufacturing difficulty of the mold for forming the first concave-convex structure 1111 can be reduced, thereby reducing the production cost of the washing machine.
[0098] In some embodiments, the first concave-convex structure 1111 is symmetrically arranged with respect to the axis of the outer drum 201 in the depth direction of the washing machine. With this arrangement, the projection of the outer drum 201 away from the axis of the outer drum 201 in the width direction of the washing machine falls within the projection area of the first concave-convex structure 1111. That is, the projection of the outer drum 201 close to the first wall 111 in the width direction of the washing machine falls within the projection area of the first concave-convex structure 1111.
[0099] In some examples, the first raised structure 111b may have a first edge 11c (see Figure 3 As shown). Exemplarily, the edge of the first protruding structure 111b on one side in the -X axis direction is the first edge 11c.
[0100] The first protruding structure 111b may have a second edge 11d. For example, the edge of the first protruding structure 111b on one side of the +X axis direction is the second edge 11d. Along the depth direction of the washing machine, the second edge 11d is arranged opposite to the first edge 11c.
[0101] In some examples, the surface of the first wall 111 facing away from the outer cylinder 201 and not provided with the first protruding structure 111b is a first surface 11e. The connection between the first edge 11c and the first surface 11e may have a first straight line segment. The connection between the second edge 11d and the first surface 11e may have a second straight line segment.
[0102] The first straight line segment may have a first center point 11c1. In the height direction of the washing machine, portions of the first straight line segment located on both sides of the first center point 11c1 are symmetrically arranged relative to the first center point 11c1.
[0103] The second straight line segment may have a second center point 11d1. In the height direction of the washing machine, portions of the second edge 11d located on both sides of the second center point 11d1 are symmetrically arranged relative to the second center point 11d1.
[0104] A line connecting the second center point 11d1 and the first center point 11c1 forms a center line C. The center line C extends along the depth direction of the washing machine.
[0105] The distance between the first edge 11c and the second edge 11d in the depth direction of the washing machine is L2. For example, the distance between the first edge 11c and the second edge 11d in the depth direction of the washing machine can be the dimension of the center line C in the depth direction of the washing machine. In other words, the dimension of the center line C in the depth direction of the washing machine is L2.
[0106] In some examples, L2 is greater than or equal to 139 mm and less than or equal to 537 mm. For example, the value of L2 can be 139 mm, 150 mm, 200 mm, 250 mm, 300 mm, 350 mm, 400 mm, 450 mm, 500 mm, or 537 mm. Of course, L2 can also be other values, and those skilled in the art can select them according to their needs. This embodiment does not limit this. If L2 is less than 139 mm, the strength of the housing 11 will be insufficient, which may cause the housing 11 to deform during operation of the washing machine. If L2 is greater than 537 mm, the first concave-convex structure 1111 will be too close to the edge of the first wall 111, which will increase the difficulty of manufacturing the mold for forming the first concave-convex structure 1111. By limiting the distance between the first edge 11c and the second edge 11d in the depth direction of the washing machine, deformation of the housing 11 during operation of the washing machine can be avoided, and the difficulty of manufacturing the mold for forming the first concave-convex structure 1111 can be reduced.
[0107] In some examples, the dimension of the first wall 111 in the depth direction of the washing machine is L3. The ratio of L2 to L3 is greater than or equal to 0.26 and less than or equal to 0.55. For example, the ratio of L2 to L3 can be 0.26, 0.3, 0.35, 0.4, 0.45, or 0.55. Of course, the ratio of L2 to L3 can also be other values, and those skilled in the art can select it according to their needs, and this embodiment does not limit this. If the ratio of L2 to L3 is less than 0.26, the distance between the first edge 11c and the second edge 11d in the depth direction of the washing machine will be too small, which will result in insufficient strength of the housing 11 and deformation of the housing during operation. If the ratio of L2 to L3 is greater than 0.55, the distance between the first edge 11c and the second edge 11d in the depth direction of the washing machine will be too large, which will cause the first concave-convex structure 1111 to be too close to the edge of the first wall 111, increasing the difficulty of manufacturing the mold for forming the first concave-convex structure 1111. By limiting the ratio of L2 to L3, deformation of the cabinet during operation of the washing machine can be avoided, and the difficulty of manufacturing the mold for forming the first concave-convex structure 1111 can be reduced.
[0108] See 5 and Figure 6 As shown, in the width direction of the washing machine, the distance between the side of the first wall 111 facing away from the outer drum 201 and the outer drum 201 may be D3. The distance between the first concave-convex structure 1111 and the outer drum 201 may be D4. The size of the first concave-convex structure 1111 may be L4.
[0109] Where D3 satisfies: D3 = D4 + L4. This arrangement allows the capacity of the case 10 to be increased while the dimensions of the case 10 remain unchanged, thanks to the first recessed structure 111a of the first concave-convex structure 1111, preventing the outer cylinder 201 from striking the case 10 when positioned away from the axis of the outer cylinder 201. While the dimensions of the case 10 remain unchanged, the volume of the cylinder assembly can be increased by the space between the first concave-convex structure 1111 and the outer cylinder 201, as well as the space within the first recessed structure 111a of the first concave-convex structure 1111.
[0110] In some embodiments, the cross-section of the first protrusion structure 111b can be trapezoidal. This configuration simplifies the mold for forming the first concave-convex structure 1111, reducing the difficulty of manufacturing the first concave-convex structure 1111. It also increases the strength of the first wall 111, effectively dispersing and transmitting externally applied forces, and reducing stress concentration.
[0111] For example, in a plane perpendicular to the height direction of the washing machine, that is, in a plane formed by the X-axis and the Y-axis, the cross section of the first protrusion structure 111b may be arranged in a trapezoidal shape. Figure 7As described above, the size of the cross section of the first protrusion structure 111 b in the X-axis direction gradually decreases along the −Y-axis direction.
[0112] In some embodiments, as shown in Figure 7, the size of the first raised structure 111b in the width direction of the washing machine is L1. Wherein, L1 is less than or equal to 5mm. For example, the value of L1 can be 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 4mm or 5mm, etc. Of course, the size of the first raised structure 111b can also be other values, and those skilled in the art can choose according to their needs. This is not limited in this embodiment. If the size of the first raised structure 111b is greater than 5mm, the size of the packaging of the washing machine will increase, which will increase the transportation cost of the washing machine. By making the size of the first raised structure 111b less than or equal to 5mm, the size of the packaging of the washing machine will not increase, thereby reducing the transportation cost of the washing machine.
[0113] In some embodiments, in the depth direction of the washing machine, the first concave-convex structure 1111 may be provided with a second concave-convex structure 1112 on both sides thereof (see FIG. Figures 1 to 4 ,as well as Figure 8 As shown). The second concave-convex structure 1112 is spaced apart from the first concave-convex structure 1111. By providing the first concave-convex structure 1111 and the second concave-convex structure 1112 on the first wall 111 of the housing 11, the rigidity of the housing 11 can be increased, the natural frequency of the housing 11 can be improved, the vibration noise of the washing machine can be reduced, and the balance performance of the drum assembly and the transport performance of the entire washing machine can be improved.
[0114] See also Figure 9 and Figure 10 As shown, the second concave-convex structure 1112 is a second concave structure 111c on the side of the first wall 111 facing the interior of the box body 11; and the second concave-convex structure 1112 is a second convex structure 111d on the side of the first wall 111 facing away from the interior of the box body 11. This arrangement can increase the volume of the box body 10 while keeping the size of the box body 10 unchanged.
[0115] For example, each of the two first walls 111 of the housing 11 may be provided with a first concave-convex structure 1111 and two second concave-convex structures 1112. In the depth direction of the washing machine, the two second concave-convex structures 1112 are symmetrically arranged relative to the first concave-convex structure 1111.
[0116] In some embodiments, in the depth direction of the washing machine, the distance between the second concave-convex structure 1112 and the first concave-convex structure 1111 is D5 (see Figure 3As shown). Wherein, D5 is greater than or equal to 5mm. For example, the value of D5 can be 5mm, 6mm, 7mm, 8mm, 9mm, 10mm or 20mm, etc. Of course, the spacing can also be other numerical values, and those skilled in the art can choose according to needs, and this embodiment is not limited to this. If the spacing between the second concave-convex structure 1112 and the first concave-convex structure 1111 is less than 5mm, it will lead to an increase in the difficulty of manufacturing the mold for forming the first concave-convex structure 1111 and the second concave-convex structure 1112, which will increase the production cost of the washing machine. By making the spacing between the second concave-convex structure 1112 and the first concave-convex structure 1111 greater than or equal to 5mm, the difficulty of manufacturing the mold for forming the first concave-convex structure 1111 and the second concave-convex structure 1112 can be reduced, thereby reducing the production cost of the washing machine.
[0117] In some embodiments, in the depth direction of the washing machine, the distance between the second concave-convex structure 1112 and the arc corner 113 may be D6 (see Figure 3 As shown). Wherein, D6 is greater than or equal to 25mm. For example, the value of D6 can be 25mm, 26mm, 27mm, 28mm, 29mm, 30mm or 40mm, etc. Of course, the spacing can also be other values, and those skilled in the art can choose according to their needs, and this embodiment does not limit this. If the spacing between the second concave-convex structure 1112 and the arc angle 113 is less than 25mm, the folding knife of the bending machine will have insufficient movement stroke during the bending process of the material forming the box body 11, so that the arc angle 113 cannot be formed between the second wall 112 and the first wall 111. By ensuring that the spacing between the second concave-convex structure 1112 and the arc angle 113 is greater than or equal to 25mm, the folding knife of the bending machine can have sufficient movement stroke during the bending process of the material forming the box body 11, so that the arc angle 113 can be formed between the second wall 112 and the first wall 111.
[0118] In some embodiments, the chassis 10 further includes a buckle 17 (see 1 to Figure 3 As shown). The buckle member 17 is provided on the housing 11. The buckle member 17 is used for carrying the washing machine.
[0119] For example, the handle 17 may be connected to the second concave-convex structure 1112 on the first wall 111 of the box body 11. The handle 17 may be embedded in the second convex structure 111d.
[0120] The buckle 17 can be fixed to the first wall 111 of the box body 11 by welding, screws, riveting, etc.
