[0055] Embodiment one

[0056] As shown in Figure 1 and Figure 2 , the present embodiment includes inner container bottom 210 and inner container side 220, which 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, and the splicing position 222 of the two ends is located on the plane, which eliminates the influence of dimensional error on the assembly structure, facilitates welding of the splicing part with the final size, the weld is neat, the welding plane processing process is simple, and the production efficiency of the dishwasher is improved.

[0057] 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.

[0058] 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.

[0059] 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 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.

[0061] The end surface of the other end 2211 of the plate is attached to the bending surface of the first bending structure 2212.

[0062] The end surface of the other end 2211 of the plate has a gap with the bending surface of the first bending structure 2212.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] In this invention, 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.

[0070] 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.

[0071] In the above scheme, the overlapping structure is a face-to-face overlapping connection, which is conducive to the splicing and positioning of each splicing component.

[0072] Preferably, one side edge of one of the two adjacent splicing components spliced with another splicing component is provided with a first connecting surface 250 extending to the outside of the inner container by bending inward, and the corresponding side edge of the other splicing component is provided with a second connecting surface 251 extending to the outside of the inner container by bending inward, and the first connecting surface 250 and the second connecting surface 251 are connected by lamination.

[0073] In the above scheme, the first connecting surface 250 and the second connecting surface 251 are welded after lamination. The first connecting surface 250 can be obtained by bending the edge of the corresponding splicing component by a certain angle, and the second connecting surface 251 is obtained by bending the edge of the other splicing 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 lamination of the surfaces can be achieved.

[0074] Referring to Figure 5 It is shown that the first connecting surface 250 and the second connecting surface 251 are both formed by bending the edge of the corresponding splicing component vertically.

[0075] Preferably, the first connecting surface 250 and the second connecting surface 251 are welded and fixed after lamination;

[0076] 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.

[0077] Referring to Figure 6 In another scheme, one side edge of one of the two adjacent splicing components spliced with another splicing component is provided with a first connecting surface 250 extending to the outside of the inner container by bending inward, and the corresponding side edge of the other splicing component is provided with a second connecting surface 251 extending to the outside of the inner container by bending inward, and the first connecting surface 250 and the second connecting surface 251 are connected by lamination. 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 laminated, the part of the second connecting surface 251 longer than the first connecting surface 250 is bent to the other surface of the first connecting surface 250, forming a three-layer laminated surface, which is bent to the outer surface of any splicing component and laminated to the outer surface. In this scheme, a three-layer laminated surface is formed, and the lap joint structure is more stable, and there is no protruding end face, which will not damage other components.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] Example 2

[0084] like Figure 8 As shown, in this embodiment, the dishwasher inner tub body 200 is composed of three splicing components, including a first splicing component, a second splicing component, and a third splicing component. The second splicing component and the third splicing component are located on both sides of the first splicing component and are parallel to the stretching direction of the dishwasher. The splicing position of the second splicing component / third splicing component and the first splicing component is located on a plane.

[0085] The first splicing component includes a bottom plate 204 of the inner liner body and a front plate 201 and a rear plate 202 connected to the bottom plate 204 and perpendicular to the stretching direction of the dishwasher.

[0086] The second / third splicing component includes a side plate 203 parallel to the stretching direction of the dishwasher. The second / third splicing component also includes an extension connected to the side plate 203 and bent toward the opposite side plate. The extension is connected to the first splicing component and includes a rounded corner structure between the inner wall surfaces. The extension is provided so that the splicing position of the second / third splicing component and the first splicing component is located on a plane.

[0087] The second splicing component / third splicing component is integrally formed by stamping. The extension 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. After forming the rounded corner structure between the inner wall surfaces, the extension continues to extend straight towards the opposite side plate. 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 / rear plate 202 in the first splicing component.

[0088] like Figure 9 The figure shown is a cross-sectional view of the inner liner body 200 of the present invention. The dishwasher is stretched by a slide rail. The side plate 203 of the second splicing component / third splicing component includes a recessed surface 2033. The recessed surface 2033 is a receiving part recessed towards the center of the inner liner. The receiving part can be fitted with a slide rail to facilitate stretching the dishwasher and taking out and putting in the tableware in the dishwasher.

[0089] Same as in Example 1, such as Figure 4 The recessed surface 2033 includes a horizontally bent surface 20331 formed by bending 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.

[0090] Preferably, in this embodiment, the bottom of the vertical bending surface 20332 is provided with a first extension surface 2031 that bends and extends toward the base plate 204, and the first extension surface 2031 is connected to the corresponding side of the base plate 204.

[0091] In the above scheme, the bottom edge of the horizontal bending surface 20331 is bent towards the bottom to form the first extension surface 2031. The first extension surface 2031 is preferably in the same plane as the base plate 204. In this way, the splicing position of the bottom edge of the base plate 204 and the side plate 203 is on the plane, not at the corner, which facilitates the splicing and alignment of each splicing part, and moves the welding position to the plane, reducing the welding difficulty.

[0092] Preferably, the side plate 203 is provided with a second extension surface 2032 on both sides, which bends and extends toward 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] Preferably, the bottom of the two side plates 203 is provided with a first extension surface 2031 bent to the bottom plate of the first splicing component, the first connecting surface 250 is arranged on the edge of the first extension surface 2031, and the second connecting surface 251 is arranged on the two sides of the bottom plate.

[0098] In the above scheme, the bottom of the side plate 203 is horizontally bent, and the edge is provided with the first connecting surface 250, 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.

[0099] Preferably, the two sides of the two side plates 203 are respectively provided with a second extension surface 2032 bent and extended to the front plate 201 and the rear plate 202, the first connecting surface 250 is arranged on the edge of the second extension surface 2032, and the second connecting surface 251 is respectively arranged on the two sides of the front plate 201 and the rear plate 202.

[0100] 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.

[0101] 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.

[0102] Example 3

[0103] like Figure 10 As shown, the difference between the structure of the inner liner body 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.

[0104] like Figure 10 As shown, this embodiment provides an inner liner structure for use in a drawer-type dishwasher, including an inner liner body 200. The inner liner body 200 is formed by an inner liner bottom 210 and an 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.

[0105] 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.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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.

[0131] Embodiment six

[0132] As shown in Figure 22 The main difference between the present embodiment and embodiment five is that the U-shaped connection structure 103 is integrally formed with the outer side plate 302. The lap plate under the U-shaped connection structure 103 and the part of the top surface of the outer side plate 302 matched with the lap plate are cancelled. This reduces the assembly parts of the dishwasher and improves the assembly efficiency.

[0133] Embodiment seven

[0134] As shown in Figure 23 to Figure 26 In the present embodiment, the side plate is provided with an outer protruding structure protruding from the inside to the outside of the inner container. The provision of the outer protruding structure increases the capacity of the inner container and realizes the expansion of the inner container.

[0135] Preferably, the inner container is slidably arranged in the housing or support of the dishwasher, the side plate comprises two side plates arranged along the sliding direction of the inner container, and the two side plates are arranged as outwardly convex structures convexly extending away from the opposite side plate, so as to increase the size of the inner container in the direction perpendicular to the sliding direction of the inner container, and increase the internal space of the inner container.

[0136] In the above scheme, the inner container body 200 comprises a front plate 201, a rear plate 202, oppositely arranged side plates 203 on both sides of the front plate, and a fillet transition side plate respectively connecting the front plate / rear plate and the side plate, and the outwardly convex structure of the side plate is obtained by stamping a large area in the middle of the side plate 203, forming a structure of the middle convex and the peripheral recovery, so as to increase the internal space of the inner container. Specifically, the outwardly convex stamping 2034 is stamped on the side plate in the direction opposite to the opposite side plate, so that the side plate is formed as a shell structure with the bottom wall convexly outward and the 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 to increase the internal space of the inner container.

[0137] Preferably, as shown in Figure 25 the side plate 203 is respectively arranged to be bent towards the front plate 201 and the rear plate 202 along the two sides in the sliding direction of the inner container, and the two sides of the outwardly convex stamping 2034 are respectively connected to the fillet transition side plate between the front plate / rear plate and the side plate through the first arc surface 207. The middle part of the outwardly convex stamping 2034 is stamped as a convex plane, and the plane of the outwardly convex stamping 2034 is transitioned to the fillet 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 smooth transition inner container is good, and the appearance is beautiful.

[0138] After the side plate 203 is stamped by the stamping 2034, a concave surface 2035 is formed at the bottom of the side plate 203, which is concave to the inner part of the inner container. The concave surface 2035 is used to avoid the slide rail of the dishwasher.

[0139] In the above scheme, the inner container is formed with a concave surface for mounting the slide rail of the dishwasher, so as to fully utilize the space in the housing of the dishwasher, and facilitate the expansion of the inner container.

[0140] Preferably, the concave surface comprises a concave surface gradually recessing into the inner container from top to bottom and a vertical surface extending downward from the end of the concave surface, and the cross-sectional profile of the concave surface cut by the vertical surface perpendicular to the side plate where the concave surface is located comprises, from top to bottom, 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, and the first curve and the second curve are smoothly connected. 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 structural design, the stretching strength of the two bending parts of the convex embossing edge, that is, the two bending parts of the concave surface 2035, is the same, the plate material is uniformly stretched, and the thickness is uniform, thereby preventing local excessive stretching from affecting the quality of the inner container.

[0141] As shown in Figure 3 and Figure 4 , in another structure, the concave surface is a concave surface directly punched into the inner container at the bottom of the side plate, and the concave surface comprises a horizontal bending surface 20331 formed by bending the bottom wall of the side plate from top to bottom into the inner container, a vertical bending surface 20332 formed by vertically bending the end of the horizontal bending surface 20331 downward, and the horizontal bending surface and the vertical bending surface are connected and transitioned through a smooth arc surface. The structure in this embodiment is different from that in Figure 4 . In this embodiment, the concave surface is indirectly formed by the convex embossing, and because the embossing is large, it cannot be punched with high strength, so it does not have a horizontal bending surface, and Figure 4 in which the concave surface is directly punched, the punching area is small, and the concave surface with a horizontal bending surface and a vertical bending surface can be punched out.

[0142] As shown in Figure 26 , the upper part of the convex embossing 2034 is connected to the top edge of the side plate 203 through a third arc surface 800, the third arc surface 800 gradually narrows toward the center of the inner container from bottom to top, the narrowing part is recessed into the inner container, and has the function of blocking the upward spraying of washing water. One convex embossing 2034 realizes multiple structural functions.

[0143] Further, the front plate / rear plate of the inner container can also be similar to the two side plates and be provided as an outward convex structure to the outer part 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 described again.

[0154] The flange is formed by bending the edge of the plate body towards the plane where the adjacent plate body is located. When the inner container includes four plate bodies, the flange is formed by vertically bending the edge of the plate body. The bending direction can be towards one side of the plate body to be spliced, or away from one side of the plate body to be spliced.
