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.

[0057] As shown in Figure 2 , the side surface of the first extension structure 2213 close to the center of the inner container inside is attached to the side surface of the other end 2211 of the plate away from the center of the inner container inside, and is integrally connected.

[0058] 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.

[0059] The vertical distance of the first bending structure 2212 bending outwardly to the inner container is equal to the thickness of the plate. 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.

[0060] The end surface of the other end 2211 of the plate is attached to the bending surface of the first bending structure 2212.

[0061] The end surface of the other end 2211 of the plate has a gap with the bending surface of the first bending structure 2212.

[0062] The gap between the end surface 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 blocking rib.

[0063] As shown in Figure 1 , the side part 220 of the inner container includes four straight side plates, and the straight side plates are connected by round corner transition side plates. The splicing position is located on the straight side plate. The straight side plate includes a front plate 201, a rear plate 202 and two side plates 203 located on both sides of the front plate. Preferably, the splicing position is located on the front plate 201.

[0064] As shown in Figure 1 , the bottom part 210 of the inner container includes a bottom plate 204 of the inner container and a connecting side wall 211 connected to the bottom plate and folded upward. The bottom part 210 of the inner container has a small containing cavity structure with an opening upward. The bottom surface of the side part 220 of the inner container is spliced with the top surface of the bottom part 210 of the inner container.

[0065] As shown in Figure 3 and Figure 4As shown, the dishwasher is stretched through the slide rail, and the connecting side wall 211 parallel to the stretching direction of the dishwasher and connected with the bottom plate 204 of the inner container is provided with a recessed accommodating portion recessed to the center of the inner container, and the recessed accommodating portion is a recessed surface 2033 recessed to the inner container 200, and the inner container is provided with the recessed surface 2033 for avoiding the slide rail, which is beneficial to the capacity expansion of the inner container, and the recessed surface 2033 is arranged on the connecting side wall 211, which is stretched small and does not affect the structural strength of the inner container.

[0066] The recessed surface 2033 includes a horizontal bending surface 20331 formed by bending the connecting side wall 211 upwardly and downwardly to the inside of the inner container, a vertical bending surface 20332 formed by vertically bending the end of the horizontal bending surface 20331 downwardly, and a smooth arc surface connecting and transitioning between the horizontal bending surface 20331 and the vertical bending surface 20332.

[0067] Preferably, the bottom of the vertical bending surface 20332 is bent and extended to the side edge corresponding to the bottom plate 204.

[0068] In the present application, the inner container of the dishwasher is divided into a plurality of spliced components, and the inner container of the dishwasher is formed by splicing, without using the existing stamping to form the inner container structure, so that the plate material is not stretched to a high degree, and the strength is insufficient even to become waste material.

[0069] Preferably, the lap joint structure includes a first connecting surface 250 arranged on one of the two adjacent spliced components and a second connecting surface 251 arranged on the other spliced component, and the first connecting surface 250 and the second connecting surface 251 are connected by surface-to-surface lapping.

[0070] In the above scheme, the lap joint structure is connected by surface-to-surface lapping, which is beneficial to the splicing and positioning of the spliced components.

[0071] Preferably, one of the two adjacent spliced components is provided with a first connecting surface 250 bent and extended to the outside of the inner container along one side edge, and the other spliced component is provided with a second connecting surface 251 bent and extended to the outside of the inner container along the corresponding side edge, and the first connecting surface 250 and the second connecting surface 251 are connected by lapping.

[0072] 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 component by a certain angle, and the second connecting surface 251 is obtained by bending the edge of the other spliced component by a certain angle, wherein the bending angle ensures that the first connecting surface 250 and the second connecting surface 251 are parallel, and the surface-to-surface lapping can be realized.

[0073] 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 component.

[0074] Preferably, the first connecting surface 250 and the second connecting surface 251 are fixed by welding after being attached.

[0075] Preferably, the first connecting surface 250 and the second connecting surface 251 have equal lengths, and the lengths are small enough not to affect the installation space of the inner container of the dishwasher. In addition, 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 cuts to the external structure.

[0076] Referring to Figure 6 In another scheme, one of the two adjacent splicing components has a first connecting surface 250 formed by bending the side edge of the splicing component inward to the outside of the inner container, and the other splicing component has a second connecting surface 251 formed by bending the side edge of the splicing component inward to the outside of the inner container. The length of the second connecting surface 251 is greater than the length of the first connecting surface 250. After the first connecting surface 250 and the second connecting surface 251 are attached, the part of the second connecting surface 251 that is longer than the first connecting surface 250 is bent to the other side of the first connecting surface 250, forming a three-layer attached surface that is bent to and attached to the outer surface of any splicing component. In this scheme, a three-layer attached surface is formed, the lap joint structure is more stable, and there is no protruding end face that can damage other components.

[0077] Referring to Figure 7 In another scheme, one of the two adjacent splicing components has a first connecting surface 250 formed by recessing the side edge of the splicing component to one side of the outside of the inner container, and the other splicing component has a second connecting surface 251 formed by recessing the side edge of the splicing component to the other side of the outside of the inner container. The side edge of the splicing component is attached to the first connecting surface 250.

[0078] In the above scheme, one of the two adjacent splicing components has a first connecting surface 250 formed by recessing the side edge of the splicing component, and the other splicing component has no change in the side edge and is directly lapped on the first connecting surface 250.

[0079] Preferably, the side edge of one splicing component is bent to form a bent section 252 away from the inner container, and the bent section 252 is bent again to form a first connecting surface 250 parallel to the side edge of the other 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 251. After the second connecting surface 251 is attached to the first connecting surface 250, the inner surfaces of the two splicing components are smoothly transitioned, thereby making the internal structure of the inner container flat.

[0080] 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.

[0081] 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.

[0082] Example 2

[0083] like Figure 8 As shown, the difference between the structure of the inner liner 200 in this embodiment and that in embodiment one is that at least one of the two ends at the splicing position 222 is provided with a notch, which is an installation port 2011 for placing a detergent adding device.

[0084] like Figure 8 As shown, this embodiment includes an inner liner 200, which is formed by the inner liner bottom 210 and the inner liner side portion 220. The inner liner side portion 220 includes a first splicing portion 2012 and a second splicing portion 2013. The first splicing portion 2012 and the second splicing portion 2013 are spliced ​​together to form a side peripheral wall. The first splicing portion 2012 and / or the second splicing portion 2013 are provided with a notch. After the first splicing portion 2012 and the second splicing portion 2013 are spliced ​​together, the notch forms an installation port 2011 for placing a detergent adding device.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] Furthermore, a fixing plate is provided at the installation port 2011. The fixing plate is located on the outside of the inner tank 200. The detergent adding device is fixedly connected to the fixing plate by screws, and thus fixed to the inner tank.

[0090] 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 200.

[0091] Example 3

[0092] In this embodiment, a sealing frame 600 is included, which is sealed and installed on the top opening of the inner liner 200. A water-blocking structure 2001 is provided on the side wall of the inner liner to prevent water from entering the gap between the sealing frame 600 and the wall of the inner liner 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 liner 200, eroding the sealing structure, extending the service life of the sealing structure, and improving the overall user experience of the product.

[0093] To avoid friction and noise during assembly between the sealing frame 600 and the inner liner 200, and to improve the tightness of the seal, a sealing ring 700 is provided between the sealing frame 600 and the inner liner 200.

[0094] like Figure 9 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 200, and enhances the safety of the dishwasher.

[0095] As shown in Figure 9 , the part of the top surface of the inner container 200 matched with the sealing frame 600 is provided with a folding structure 2002 outward of the inner container, the end of the folding structure 2002 has an included angle with the wall surface of the inner container 200, and is inclined outward of the inner container. 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 the lower surface protrudes towards the inner container. The end of the folding structure 2002 is clamped 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 wall surface of the inner container, and the end of the folding structure 2002 is pushed away from the lower surface of the through hole 601, which is simple to operate and brings good user experience.

[0096] As a further limitation of the embodiment, the folding structure 2002 on the top surface of the inner container 200 is arranged at intervals or continuously, and the through hole 601 on the sealing frame 600 corresponds to the folding structure 2002 one by one and cooperates with each other, which is beneficial to demolding of the sealing frame 600 and enhances the compactness of the sealing.

[0097] In the embodiment, the inner container 200 includes four side plates with straight and flat top surfaces, and the side plates are connected by rounded transition side plates. The water blocking structure 200 is located on the upper part of the side plate.

[0098] Embodiment Four

[0099] The difference between the embodiment and embodiment three is that the water blocking structure 2001 is located on the lower edge of the sealing frame 600.

[0100] As shown in Figure 10 , the water blocking structure 2001 is a protruding structure recessed towards the center of the inner container, and the height of the protruding structure is greater than or equal to the gap between the wall surface of the sealing frame and the main body of the inner container. This structure can well block the gap between the sealing frame 600 and the wall surface of the inner container 200, avoid the washing water entering the gap to flush the sealing ring 700, and prevent long-term flushing from damaging the sealing ring 700 to cause water leakage. At the same time, it also reduces the failure rate of the dishwasher, prolongs the life cycle of the product, and improves the user experience.

[0101] Embodiment Five

[0102] As shown in Figure 11As shown, the embodiment includes connecting structure 100, inner container 200, door body 301, outer plate 302, bottom cover 400 and bottom support 500. The inner container 200 is an upwardly open dishwasher inner container structure. In order to facilitate the assembly and use of the dishwasher, bottom cover 400 and bottom support 500 are arranged at the bottom of the inner container. The bottom support 500 plays a supporting and fixing role on the inner container structure. The lower part of the bottom support 500 is provided with guide rails for facilitating the stretching of the dishwasher. The dishwasher will produce noise during use. In order to reduce the noise during use of the dishwasher and improve the overall aesthetics of the dishwasher, the outer plate 302 is arranged on both sides of the inner container parallel to the stretching direction of the dishwasher. The upper part of the outer plate 302 is connected to the top surface of the dishwasher inner container 200 through the connecting structure 100, and the lower part of the outer plate 302 is connected to the bottom support 500. In order to facilitate the stretching of the dishwasher, the door body 301 is arranged on the dishwasher. The inner container 200 and the door body 301 are connected through the connecting structure 100. The lower part of the door body 301 is connected to the bottom support 500. In order to improve the overall stability and safety of the dishwasher, the outer plate 302 is connected to the inner container 200, and at the same time connected to the door body 301 and the bottom support 500.

[0103] The embodiment includes an upwardly open inner container 200, an outer plate located on the side of the inner container body, and a connecting structure 100 connecting the inner container body and the outer plate.

[0104] As shown, Figure 12 The inner container 200 includes a side plate with a flat top surface. The side plates are connected by a round corner transition side plate.

[0119] Example 6

[0120] like Figure 21 As shown, the main difference between this embodiment and embodiment five is that the connecting structure 100 connected to the top surface of the opening of the inner liner 200 is different. The connecting structure 100 in this embodiment includes a straight connecting structure 1001 connected to the front plate 201 and the rear plate 202 of the inner liner 200 respectively. Preferably, the straight connecting structure 1001 is integrally formed with the front plate 201 / rear plate 202. The connecting structure 100 also includes a U-shaped connecting structure 103 connected to the side plate 203 of the inner liner 200 respectively. The overall shape of the U-shaped connecting structure 103 is consistent with the overall shape formed by the straight connecting structure 1001 connected to the top surface of the side plate 203 and the rounded corner connecting structures 1002 located on both sides of the straight connecting structure 1001 in embodiment one. The U-shaped connecting structure 103 is an integrally formed structure. The U-shaped connecting structure 103 is also provided with an overlapping plate connected to the outer side plate 302. The overlapping plate is provided with a groove that cooperates with the protrusion on the top surface of the outer side plate 302.

[0121] Example 7

[0122] like Figure 22 As shown, the main difference between this embodiment and embodiment six 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.

[0123] Example 8

[0124] See Figures 23 to 26 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.

[0125] 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.

[0126] In the above scheme, the inner container 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 internal 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 internal space of the inner container.

[0127] Preferably, as shown in Figure 25 The side plate 203 is bent 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.

[0128] After the side plate 203 is stamped by the stamping 2034, a concave surface 2035 is formed on the bottom of the side plate 203, which is recessed towards the inside of the inner container. The concave surface 2035 is used to avoid the slide rail of the dishwasher.

[0129] 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.

[0130] 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 on which it is located, includes a first curve 20351 with a center of curvature inside the inner container and a second curve 20352 with a center of curvature 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. With this structure, the edges of the outer convex stamping, or the two bends of the concave surface 2035, have 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.

[0131] 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 being bent 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 being vertically bent 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.

[0132] Referring to Figure 26 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 toward the center of the inner container from bottom to top, and the narrowed part is recessed into 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.

[0133] 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.

[0134] 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 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.
