[0056] Embodiment one

[0057] As shown in Figure 1 and Figure 2 , the present embodiment includes inner container bottom 210 and inner container side 220, the inner container bottom 210 and the inner container side 220 constitute an open upward inner container main body 200, the inner container side 220 is a piece of plate folded into a ring shape, one end of the plate has a splicing part 221, the other end is overlapped on the splicing part 221, the splicing position 222 of the two ends is located on the plane, eliminating the influence of dimensional error on the assembly structure, facilitating the welding of the splicing part with the final size, the weld is regular, the welding plane processing technology is simple, and the manufacturing efficiency of the dishwasher is improved.

[0058] As shown in Figure 2 , the splicing part 221 is a bending structure formed by bending one end of the plate, the end of the bending structure is parallel to the other end 2211 of the plate, the bending structure includes a first bending structure 2212 and a first extension structure 2213, the first bending structure 2212 is formed by bending one end of the plate outward, and the first extension structure 2213 is formed by bending and extending the end of the first bending structure 2212, and is parallel to the other end 2211 of the plate.

[0059] As shown in Figure 2 , the side surface of the first extension structure 2213 close to the inner container center is attached to the side surface of the other end 2211 of the plate away from the inner container center, and is integrally connected.

[0060] The inner wall surface of one end of the plate before bending is flush with the inner wall surface of the other end 2211 of the plate.

[0061] The perpendicular distance of the first bending structure 2212 bending outward is equal to the thickness of the plate, and the inner wall surface of one end of the plate before bending is flush with the inner wall surface of the other end 2211 of the plate.

[0062] The end surface of the other end 2211 of the plate is attached to the bending surface of the first bending structure 2212.

[0063] The end face of the other end 2211 of the plate has a gap with the bending surface of the first bending structure 2212.

[0064] The gap between the end face of the other end 2211 of the plate and the bending surface of the first bending structure 2212 is filled with welding material, sealing strip, or baffle.

[0065] like Figure 1 As shown, the inner liner side 220 includes four flat side panels, with rounded corner transition side panels between them. The splicing position is located on the flat side panels. The flat side panels include a front panel 201, a rear panel 202, and two side panels 203 located on both sides of the front panel. Preferably, the splicing position is located on the front panel 201.

[0066] like Figure 1 As shown, the bottom of the inner liner 210 includes a bottom plate 204 of the inner liner and a connecting side wall 211 that is connected to the bottom plate and folded upward. The bottom of the inner liner 210 has an upward-opening structure with a small accommodating cavity. The bottom surface of the side portion 220 of the inner liner is spliced ​​with the top surface of the bottom of the inner liner 210.

[0067] like Figure 3 and Figure 4 As shown, the dishwasher is stretched by a slide rail. The connecting side wall 211, which is connected to the bottom plate 204 of the inner tub and is parallel to the stretching direction of the dishwasher, is provided with a receiving part that is recessed towards the center of the inner tub. The receiving part is a recessed surface 2033 that is recessed into the inner tub body 200. The inner tub is provided with a recessed surface 2033 to avoid the slide rail, which is conducive to the expansion of the inner tub. Moreover, the recessed surface 2033 on the connecting side wall 211 results in small stretching and does not affect the structural strength of the inner tub.

[0068] The concave surface 2033 includes a horizontally bent surface 20331 formed by bending the connecting side wall 211 from top to bottom into the inner liner, and a vertically bent surface 20332 formed by bending the end of the horizontally bent surface 20331 downwards. The horizontally bent surface 20331 and the vertically bent surface 20332 are connected and transitioned by a smooth arc surface.

[0069] Preferably, the bottom of the vertical bending surface 20332 bends and extends towards the base plate 204, connecting with the corresponding side of the base plate 204.

[0070] In this embodiment, the dishwasher inner liner is divided into multiple splicing parts, which are spliced ​​together to form the dishwasher inner liner, instead of using the existing stamping to form the inner liner structure. This avoids the problem that the sheet material is not strong enough after being stretched to a high degree, or even becomes waste material.

[0071] Preferably, the overlapping structure includes a first connecting surface 250 on one of two adjacent splicing components and a second connecting surface 251 on the other splicing component, wherein the first connecting surface 250 and the second connecting surface 251 are fitted together.

[0072] In the above scheme, the lap joint structure is a face-to-face lap joint connection, which is beneficial for the positioning of the spliced parts.

[0073] Preferably, in the two adjacent spliced parts, one side edge of one spliced part spliced with another spliced part is provided with a first connecting surface 250 extending to the outside of the inner container, and the corresponding side edge of the other spliced part is provided with a second connecting surface 251 extending to the outside of the inner container, and the first connecting surface 250 and the second connecting surface 251 are connected by lapping.

[0074] In the above scheme, the first connecting surface 250 and the second connecting surface 251 are welded after lapping. The first connecting surface 250 can be obtained by bending the edge of the corresponding spliced part by a certain angle, and the second connecting surface 251 is obtained by bending the edge of the other spliced part by a certain angle, wherein the bending angle ensures that the first connecting surface 250 and the second connecting surface 251 are parallel, which can be achieved by lapping the face-to-face.

[0075] Referring to Figure 5 As shown, the first connecting surface 250 and the second connecting surface 251 are both formed by vertically bending the edge of the corresponding spliced part.

[0076] Preferably, the first connecting surface 250 and the second connecting surface 251 are welded and fixed after lapping;

[0077] Preferably, the first connecting surface 250 and the second connecting surface 251 have equal lengths, and both lengths are very small and do not affect the installation space of the inner container of the dishwasher, and the lengths of the first connecting surface 250 and the second connecting surface 251 are equal, and the width of the end face formed after welding is not easy to cause damage to the external structure.

[0078] Referring to Figure 6 As shown, in another scheme, in the two adjacent spliced parts, one side edge of one spliced part spliced with another spliced part is provided with a first connecting surface 250 extending to the outside of the inner container, and the corresponding side edge of the other spliced part is provided with a second connecting surface 251 extending to the outside of the inner container, and the length of the second connecting surface 251 is greater than the length of the first connecting surface 250, and after the first connecting surface 250 and the second connecting surface 251 are lapped, the part of the second connecting surface 251 longer than the first connecting surface 250 is bent to the other face of the first connecting surface 250, forming a three-layer lapping surface, which is bent to the outer surface of any spliced part and lapped with the outer surface. In this scheme, a three-layer lapping surface is formed, the lap joint structure is relatively stable, and there is no protruding end face, which will not damage other parts.

[0079] Referring to Figure 7As shown, in another embodiment, among two adjacent splicing components, one splicing component and the other splicing component have a first connecting surface 250 formed by a recess on one side of the splicing component that extends outward from the inner liner. The corresponding edge of the other splicing component is the second connecting surface 251, and the corresponding edge of the splicing component is attached to the first connecting surface 250.

[0080] In the above scheme, among two adjacent splicing components, one splicing component has a recessed edge to form a first connecting surface 250, while the edge of the other splicing component remains unchanged and can be directly overlapped on the first connecting surface 250.

[0081] Preferably, the edge of one splicing component is first bent away from the inner liner to form a bent section 252. The bent section 252 is bent again to form a first connecting surface 250 parallel to the edge of another splicing component. The height of the bent section 252 in the direction perpendicular to the first connecting surface 250 matches the thickness of the second connecting surface. After the second connecting surface 251 is attached to the first connecting surface 250, the inner surfaces of the two splicing components transition smoothly, thereby making the internal structure of the inner liner flat.

[0082] In this embodiment, the bottom 210 of the inner liner is the first splicing component, and the side 220 of the inner liner is the second splicing component. A first connecting surface 250 is provided on the splicing edge of the bottom 210 or the side 220 of the inner liner, and a second connecting surface 251 is provided on the edge of the side 220 or the bottom 210 of the inner liner. The first connecting surface 250 and the second connecting surface 251 are connected.

[0083] The bottom 210 of the inner liner is provided with a connecting side wall 211 so that the splicing position is on a plane, and the overlapping structure can prevent the two splicing parts from processing errors, can be stably overlapped, and then welded and fixed.

[0087] The second splicing component / third splicing component includes a side plate 203 parallel to the stretching direction of the dishwasher, and further includes an extension part bent to the direction of the opposite side plate and connected to the first splicing component, and the extension part contains a fillet structure between the inner container wall surfaces, and the extension part is arranged to make the splicing position of the second splicing component / third splicing component and the first splicing component located on a plane.

[0088] The second splicing component / third splicing component is integrally formed by stamping, and the extension part includes a first extension surface 2031 located on the bottom surface of the side plate 203 and a second extension surface 2032 located on the side surface of the side plate 203, and the extension part is continued to extend straight to the direction of the opposite side plate after forming the fillet structure between the inner container wall surfaces, the first extension surface 2031 is connected to the bottom plate 204 in the first splicing component, and the second extension surface 2032 is connected to the front plate 201 or the rear plate 202 in the first splicing component.

[0090] As shown in FIG. 1, the side plate 203 of the second splicing component / third splicing component includes a recessed surface 2033, and the recessed surface 2033 is a containing part recessed to the center of the inner container. Figure 4 The recessed surface 2033 includes a horizontal bending surface 20331 bent to the inside of the inner container from top to bottom, a vertical bending surface 20332 vertically bent downward at the end of the horizontal bending surface 20331, and the horizontal bending surface 20331 and the vertical bending surface 20332 are connected and transitioned through a smooth arc surface.

[0092] In the above scheme, the bottom edge of the horizontal bending surface 20331 is bent to the bottom to form the first extension surface 2031, and the first extension surface 2031 is preferably in the same plane as the bottom plate 204, so that the splicing position of the bottom plate 204 and the lower edge of the side plate 203 is on the plane, not at the corner, which facilitates the splicing and alignment of the splicing parts, and moves the welding position to the plane, reducing the welding difficulty.

[0093] Preferably, the two sides of the side plate 203 are respectively provided with a second extension surface 2032 bent and extended to the front plate 201 and the rear plate 202, and the second extension surface 2032 is connected to the corresponding front plate 201 or rear plate 202.

[0094] In the above scheme, the two sides of the side plate 203 are bent to form the second extension surface 2032, which is spliced with the front plate 201 or the rear plate 202, and the side of the second extension surface 2032 spliced with the front plate 201 or the rear plate 202 is in the same plane as the front plate 201 or the rear plate 202, thereby avoiding the corner and facilitating welding.

[0095] In the embodiment, the design of the second extension surface 2032 prevents splicing on the recessed surface 20352033 and transfers the splicing position to the plane, thereby simplifying the welding process.

[0096] In the embodiment, the front plate 201 is provided with a mounting opening 2011 of a detergent adding device, thereby facilitating the addition of washing liquid.

[0097] In the embodiment, the bottom plate 204, the front plate 201, and the rear plate 202 form a first splicing component, the two side plates 203 are respectively a second splicing component and a third splicing component, the connection mode between the splicing components is the same as that in the first embodiment, the first connecting surface 250 is arranged on the two sides of the first splicing component, the second connecting surface 251 is arranged on the two sides and the bottom edge of the two side plates 203, and the first connecting surface 250 is connected with the second connecting surface 251.

[0101] Similarly, the design of the second extension surface 2032 avoids the corner between the side plate 203 and the front plate 201 or the rear plate 202, so that the splicing position is located on the plane and the two splicing components can prevent machining errors and can be stably overlapped and then welded and fixed.

[0102] Preferably, the first extension surface 2031 and the second extension surface 2032 smoothly transition to form a U-shaped arc surface, and the U-shaped arc surface smoothly joins the notch side of the first splicing component.

[0103] Example 3

[0106] Specifically, the first splicing part 2012 includes a first splicing surface formed by the vertical connection of a first side and a first bottom edge, and the second splicing part 2013 includes a second splicing surface formed by the vertical connection of a second side and a second bottom edge. The first side and / or the second side are provided with a notch. The first side of the first splicing surface and the second side of the second splicing surface are aligned so that the first splicing surface and the second splicing surface are located on the same horizontal plane. When splicing, the notch forms an installation port 2011 that can be used to place a detergent adding device. The size of the notch can be set to different sizes and shapes according to the size of the detergent adding device.

[0107] For example, a notch can be opened on the first side of the first splicing surface, and a notch can be opened at the corresponding position on the second side. When the first splicing surface and the second splicing surface are spliced, the middle notch of the first side and the middle notch of the second side form an installation port 2011 that can be used to place a detergent adding device.

[0108] As an alternative to the above solution, a notch can also be provided on one side edge of the first or second splicing surface. For example, a notch can be provided on one side edge of the first splicing surface. When the first and second splicing surfaces are spliced, the notch portion of the first splicing surface and the splicing position 222 of the second splicing surface form an installation opening 2011 for placing a detergent dispensing device. Alternatively, a notch can be provided on one side edge of the second splicing surface.

[0109] In this embodiment, an installation port 2011 for placing a detergent additive device is formed at the splicing position 222, which reduces the length of the weld and can even eliminate the intermediate weld, thus reducing welding steps and saving costs.

[0110] Furthermore, a fixing plate is provided at the installation port 2011. The fixing plate is located on the outside of the inner tank body 200. The detergent adding device is fixedly connected to the fixing plate by screws, and thus fixed to the inner tank.

[0111] Preferably, a rubber ring or other sealing structure matching the shape and size of the mounting port 2011 is provided between the fixing plate and the detergent adding device to increase the sealing between the detergent adding device and the inner tank body 200.

[0112] Example 4

[0113] In this embodiment, a sealing frame 600 is included, which is sealed and installed on the top opening of the inner tank body 200. A water-blocking structure 2001 is provided on the side wall of the inner tank to prevent water from entering the gap between the sealing frame 600 and the wall of the inner tank body 200. The water-blocking structure can effectively prevent washing water from entering from the gap between the sealing frame 600 and the wall of the inner tank body 200, thus preventing it from eroding the sealing structure, extending the service life of the sealing structure, and improving the overall user experience of the product.

[0114] To avoid friction and noise during assembly between the sealing frame 600 and the inner liner body 200, and to improve the tightness of the seal, a sealing ring 700 is provided between the sealing frame 600 and the inner liner body 200.

[0115] like Figure 11 As shown, in this embodiment, the water-blocking structure 2001 is a protruding structure recessed towards the center of the inner liner. The surface of the protruding structure is arc-shaped. The sealing frame 600 is provided with a receiving portion. The water-blocking structure 2001 is snapped into the receiving portion. The receiving portion is a groove recessed towards the center of the inner liner. The inner surface of the groove has the same shape as the outer surface of the water-blocking structure 2001, which facilitates the installation of the sealing frame 600. This increases the tightness of the sealing structure, improves the compactness of the assembly between the sealing frame 600 and the inner liner body 200, and enhances the safety of the dishwasher.

[0116] like Figure 11As shown, the top surface of the inner liner body 200 that mates with the sealing frame 600 is provided with a folding structure 2002 extending outward from the inner liner. The end of the folding structure 2002 forms an angle with the wall surface of the inner liner body 200 and tilts outward from the inner liner. The sealing frame 600 is provided with a through hole 601. The lower surface of the through hole 601 is longer than the upper surface and protrudes towards the inner liner. The end of the folding structure 2002 is engaged on the lower surface of the through hole 601. When disassembling the sealing frame 600, a tool smaller than the diameter of the through hole 601 is used to enter the through hole 601 from the side away from the inner liner wall and push the end of the folding structure 2002 away from the lower surface of the through hole 601. The operation is simple and provides users with a good user experience.

[0117] As a further limitation of this embodiment, the folding structure 2002 located on the top surface of the inner liner body 200 is arranged at intervals or continuously, and the through hole 601 on the sealing frame 600 corresponds one-to-one with the folding structure 2002 and cooperates with each other, which is conducive to the demolding of the sealing frame 600 and enhances the compactness of the seal.

[0118] In this embodiment, the inner liner body 200 includes four side plates with flat top surfaces, which are connected by rounded corner transition side plates. The water-blocking structure 200 is located on the upper part of the side plates.

[0119] Example 5

[0120] The difference between this embodiment and embodiment four is that the water-blocking structure 2001 is located at the lower edge of the sealing frame 600.

[0121] like Figure 12 As shown, the water-blocking structure 2001 is a protruding structure recessed towards the center of the inner tub. The height of the protruding structure is greater than or equal to the gap between the sealing frame and the inner tub body. This structure can effectively seal the gap between the sealing frame 600 and the inner tub body 200, preventing washing water from entering through the gap and rinsing the sealing ring 700. Prolonged rinsing can damage the sealing ring 700 and cause leakage. It also reduces the failure rate of the dishwasher, extends the product life cycle, and improves the user experience.

The bottom surface of the flat connecting structure 1001 is a flat surface consistent with the shape of the top surface of the side wall. After being connected to the top surface of the side wall, the flat connecting structure 1001 is folded outward to the outside of the inner container main body 200. In the embodiment, the flat connecting structure 1001 is integrally formed with the side plate, greatly reducing the length of the weld seam in the processing of the dishwasher and improving the efficiency of product production.

[0127] The rounded connecting structure 1002 is in the shape of an angle. The bottom surface of the rounded connecting structure 1002 is a circular arc surface consistent with the shape of the rounded transition side plate between the side plate. The end surfaces of the rounded connecting structure 1002 on both sides are consistent with the shape of the end surfaces of the adjacent flat connecting structure 1001. The end surfaces of the rounded connecting structure 1002 on both sides are spliced with the adjacent flat connecting structure 1001. The top surface of the rounded transition side plate between the bottom surface and the side plate is spliced. After splicing, the rounded connecting structure 1002 is folded outward to the outside of the inner container main body 200. The weld seam only appears on the end surfaces spliced with the adjacent flat connecting structure and the top surface spliced with the rounded transition side plate. The length of the weld seam is greatly reduced, and the overall appearance of the dishwasher is improved.

Figure 22As shown, this structure greatly reduces the connection gap between the outer panel 302 and the overlapping plate, preventing the outer panel 302 from shifting and generating noise during the operation of the dishwasher.

[0140] Example 7

[0141] like Figure 23 As shown, the main difference between this embodiment and Embodiment Six lies in the connection structure 100 connected to the top surface of the opening of the inner liner body 200. In this embodiment, the connection structure 100 includes a straight connection structure 1001 connected to the front plate 201 and the rear plate 202 of the inner liner body 200 respectively. Preferably, the straight connection structure 1001 is integrally formed with the front plate 201 / rear plate 202. The connection structure 100 also includes a U-shaped connection structure 103 connected to the side plate 203 of the inner liner body 200 respectively. The overall shape of the U-shaped connection structure 103 is consistent with the overall shape formed by the straight connection structure 1001 connected to the top surface of the side plate 203 and the rounded corner connection structures 1002 located on both sides of the straight connection structure 1001 in Embodiment One. The U-shaped connection structure 103 is an integrally formed structure. The U-shaped connection structure 103 is also provided with an overlapping plate connected to the outer plate 302. The overlapping plate is provided with a groove that cooperates with the protrusion on the top surface of the outer plate 302.

[0142] Example 8

[0143] like Figure 24 As shown, the main difference between this embodiment and embodiment seven is that the U-shaped connecting structure 103 and the outer side plate 302 are integrally formed, eliminating the overlapping plate under the U-shaped connecting structure 103 and the part where the top surface of the outer side plate 302 mates with the overlapping plate, reducing the number of assembly parts for the dishwasher and improving assembly efficiency.

[0144] Example 9

[0145] See Figure 25 to Figure 27 As shown, in this embodiment, the side plate is provided with an outward protrusion structure that protrudes from the inside of the inner liner to the outside. The outward protrusion structure increases the capacity of the inner liner, thus expanding the inner liner's capacity.

[0146] Preferably, the inner liner is slidably disposed within the shell or bracket of the dishwasher, and the side plate includes two side plates extending along the sliding direction of the inner liner. Both side plates are configured as outwardly convex structures protruding away from the opposite side plate, thereby increasing the size of the inner liner and increasing the internal space of the inner liner in a direction perpendicular to the sliding direction of the inner liner.

[0147] In the above scheme, the inner container body 200 includes a front plate 201, a rear plate 202, oppositely arranged side plates 203 on both sides of the front plate, and a rounded transition side plate respectively connecting the front plate / rear plate and the side plate. The outer convex structure of the side plate is obtained by stamping a large area in the middle of the side plate 203, forming a middle convex structure, and a structure with a peripheral wall extending to the side of the opposite side plate, thereby increasing the inner space of the inner container. Specifically, the outer convex stamping 2034 is stamped in the opposite direction of the opposite side plate on the side plate, forming a shell structure in which the side plate is shaped as a bottom wall with an outer convex structure and a peripheral wall extending to the side of the opposite side plate. In this way, a large area in the middle of the side plate is stamped, increasing the inner space of the inner container.

[0148] Preferably, as shown in Figure 27 , the side plate 203 is provided with a bend towards the front plate 201 and the rear plate 202 on both sides along the sliding direction of the inner container, and the two sides of the outer convex stamping 2034 are respectively connected to the rounded transition side plate between the front plate / rear plate and the side plate through the first arc surface 207. The middle part of the outer convex stamping 2034 is stamped into a convex plane, and the plane of the outer convex stamping 2034 is transitioned to the rounded transition side plate through the first arc surface 207. In this way, the stamping strength of the side plate is small, the strength of the manufactured inner container is high, the quality is good, and the overall gloss of the smoothly transitioned inner container is good, and the appearance is beautiful.

[0149] After the side plate 203 is stamped by the stamping 2034, a concave surface 2035 is formed in the bottom of the side plate 203, which is recessed towards the inner container. The concave surface 2035 is used to avoid the slide rail of the dishwasher.

[0150] In the above scheme, the inner container is formed with a concave surface for mounting the slide rail of the dishwasher, thereby fully utilizing the space inside the dishwasher shell and facilitating the expansion of the inner container.

[0151] Preferably, the concave surface includes a concave surface that gradually recedes into the inner container from top to bottom and a vertical surface that extends downward from the end of the concave surface. The cross-sectional profile of the concave surface, which is longitudinally sectioned by the vertical surface perpendicular to the side plate where the concave surface is located, includes a first curve 20351 with a curvature center inside the inner container and a second curve 20352 with a curvature center outside the inner container from top to bottom. The first curve and the second curve smoothly transition. Preferably, the length of the first curve is equal to the length of the second curve. More preferably, the curvature of the first curve is equal to the curvature of the second curve. Through this structure design, the edge of the outer convex stamping, or the two bends of the concave surface 2035, has the same tensile strength, the plate material is uniformly stretched, and the thickness is uniform, thereby preventing local excessive stretching from affecting the quality of the inner container.

[0152] Referring to Figure 3 and Figure 4As shown, in another structure, the recessed surface is a recessed surface directly punched at the bottom of the side plate to the inner part of the inner container, which includes a horizontal bending surface 20331 formed by the bottom wall of the side plate first bending from top to bottom to the inner part of the inner container, a vertical bending surface 20332 formed by the end of the horizontal bending surface 20331 bending vertically downward, and a smooth arc surface connecting and transitioning between the horizontal bending surface and the vertical bending surface. The structure in this embodiment is different from that in Figure 4 In this embodiment, the recessed surface is indirectly formed by the extruded convex profile, and because the profile is large, it cannot be punched with high strength, so it does not have a horizontal bending surface, and Figure 4 In this embodiment, the recessed surface is directly punched, the punching area is small, and the recessed surface with a horizontal bending surface and a vertical bending surface can be punched out.

[0153] Referring to Figure 28 As shown, the upper part of the convex profile 2034 is connected to the top edge of the side plate 203 by a third arc surface 800, which gradually narrows towards the center of the inner container from bottom to top, and the narrowed part is recessed towards the inner part of the inner container, which has the function of blocking the upwardly sprayed washing water, and one convex profile 2034 realizes multiple structural functions.

[0154] Further, the front plate / rear plate of the inner container can also be similar to the two side plates and be provided as a convex structure to the outside of the inner container to realize the expansion of the inner container. The structure can be similar to the above two side plates, and will not be repeated again.

[0155] The above only describes the preferred embodiments of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above, it is not intended to limit the present application, and any skilled person in the art can make some changes or modifications to the above-mentioned technical content without departing from the scope of the technical solution of the present application, and any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the present application are still within the scope of the present application.
