[0046] like Figure 1 As shown, a drawer-type dishwasher of the present invention includes a connecting structure 100, an inner tank body 200, a door body 301, an outer panel 302, a bottom cover 400 and a bottom support 500. The inner tank body 200 is an inner tank structure of a dishwasher with an upward opening. In order to facilitate the assembly and use of the dishwasher, a bottom cover 400 and a bottom support 500 are provided at the bottom of the inner tank. The bottom support 500 plays a supporting and fixing role for the inner tank structure. The lower part of the bottom support 500 is provided with a guide rail for facilitating the stretching of the dishwasher. The dishwasher will generate noise during use. In order to reduce the noise during use of the dishwasher and to improve the overall aesthetics of the dishwasher, Outer panels 302 are provided on the outside of both sides of the inner tank parallel to the stretching direction of the dishwasher. The upper part of the outer panel 302 is connected to the top surface of the inner tank body 200 of the dishwasher via a connecting structure 100, and the lower part of the outer panel 302 is connected to the bottom support 500. In order to prevent the dishwasher from stretching, a door body 301 is provided on the dishwasher. The inner tank body 200 and the door body 301 are connected via a connecting structure 100, and 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 panel 302 is connected to the inner tank body 200 as well as to the door body 301 and the bottom support 500.

[0047] Example 1

[0048] like Figure 2 As shown, this embodiment provides a dishwasher inner container, comprising: an inner container body 200, the inner container body 200 having a accommodating cavity with a top opening, the open end of the inner container body 200 being provided with a connecting structure 100 extending outward from the inner container body 200, specifically, a first connecting structure 101 being provided at a first side edge of the open end; an outer plate 302, the outer plate 302 comprising an outer plate body 3021 and a second connecting structure 102 located at an upper end of the outer plate body 3021, the second connecting structure 102 and the outer plate body 3021 being an integrally formed structure; the second connecting structure 102 of the outer plate 302 being fixedly connected to both adjacent side edges of the first side edge. The present invention adopts an integral structure of the second connecting structure 102 and the outer plate body 3021, and when the inner container body 200 and the outer plate 302 are connected, the connection between the intermediate connecting structure 100 and the outer plate 302 is reduced, thereby reducing the number of welding steps.

[0049] Specifically, the second connecting structure 102 is a connecting flange that is integrally provided with the outer panel body 3021 and is formed by bending and stretching from the end of the outer panel body 3021. The outer panel body 3021 is used to cover the outer side of the inner liner body 200 and serves as a decoration. The connecting flange is used to connect the outer panel 302 and the inner liner body 200.

[0050] like Figure 3 As shown, the connecting flange includes a planar portion 1001, an extension portion 1003 and a curved portion 1002 connected between the planar portion 1001 and the extension portion 1003, the planar portion 1001 is fixedly connected to a side edge adjacent to the first side edge, the curved portion 1002 is fixedly connected to the corner where the first side edge and the adjacent side edge of the inner liner body 200 intersect, and the extension portion 1003 is spliced at both side ends of the first connecting structure 101.

[0051] Furthermore, the upper end of the outer plate body 3021 extends toward the inner liner body 200 to form a planar portion 1001 for the connecting flange. One side end of the planar portion 1001 smoothly transitions and extends toward the first side edge to form a curved portion 1002. The curvature of the curved portion 1002 matches the curvature of the intersection of the two adjacent edges of the open end of the inner liner body 200. The end of the curved portion 1002 extends horizontally toward the first connecting structure 101 to form an extension portion 1003. The end of the extension portion 1003 is connected to the end of the first connecting structure 101. Preferably, the planar portion 1001 and the curved portion 1002 are integrally bent and formed, without the use of welding, clamping, screwing, or other connection methods, thereby increasing the strength of the connecting flange and improving production efficiency.

[0052] Furthermore, the connecting flange includes a first vertical connecting surface 1004 , which is formed by extending downward from the edge of the connecting flange close to the inner liner body 200 , and the first vertical connecting surface 1004 is fixedly connected to the opening of the inner liner body 200 .

[0053] Furthermore, the first connection structure 101 is a flange structure formed by bending the first side edge toward the outside of the inner tank body 200. The flange structure is fixedly connected to the door body 301 of the dishwasher, and the two side ends of the flange structure are fixedly connected to the extension portion 1003 of the connecting flange.

[0054] Specifically, the flange structure is a horizontal flange structure formed by extending the first side edge vertically upward and then folding toward the outside of the inner tank body 200. The horizontal flange structure is connected to the door body 301 of the dishwasher. The two end edges of the horizontal flange structure are connected to the end of the extension part 1003 of the connecting flange. The side edges of the horizontal flange extend downward or upward to form a connecting surface that fits with the door body 301 of the dishwasher, and are fixedly connected by screws or welding. The two end edges of the horizontal flange are fixedly connected to the end of the extension part 1003.

[0055] In the above scheme, one side edge of the inner tank body 200 is bent outward to form a flange structure, and the flange structure is used to connect the door body 301 of the dishwasher. Since the flange structure and the inner tank body 200 are an integrated structure, when the inner tank body 200 and the door body 301 are connected, the connection process of the inner tank body 200 and the intermediate connecting structure 101 is reduced, which greatly reduces the length of the weld during the processing of the dishwasher, improves the efficiency of product production, reduces the weld, and strengthens the strength of the inner tank.

[0056] Furthermore, the inner liner body 200 also includes a third connecting structure 103 arranged on a second side edge opposite to the first side edge. The third connecting structure 103 is a flange structure extending from the second side edge toward the outside of the inner liner body 200. The two ends of the planar portion 1001 of the second connecting structure 102 are smoothly extended to form a curved portion 1002 and an extension portion 1003. The two ends of the second connecting structure 102 and the ends of the first connecting structure 101 and the third connecting structure 103 are spliced together at the open end of the inner liner body 200 to form a closed connecting structure 100.

[0057] Furthermore, one side edge of the outer panel body 3021 close to the door body 301 extends toward the outside of the inner tank body 200 to form an extension surface parallel to the plane where the door body 301 is located. The extension surface is tightly fitted with the door body 301, and a threaded hole is provided on the extension surface and is fixedly connected to the door body 301 of the dishwasher by screws. In order to facilitate the assembly and use of the dishwasher, a bottom cover 400 and a bottom support 500 are provided at the bottom of the inner tank. The bottom support 500 plays a supporting and fixing role for the inner tank structure. The lower end of the outer panel body 3021 is fixedly connected to the bottom support 500 of the dishwasher.

[0058] The outer panel 302 provided in the present invention not only serves as a decoration, but is also equivalent to the outer shell in the prior art. Compared with the outer shell in the prior art, it not only saves materials, but also does not require a separate fixing structure to fix the outer panel 302 and the inner liner body 200, and the stability between the inner liner body 200 and the outer panel 302 is higher.

[0059] The molding process of the dishwasher inner tank in this embodiment includes the following steps:

[0060] (1) Making the liner body 200 by stamping and / or stretching and / or splicing according to the liner size;

[0061] (2) Determine the size of the outer plate 302 based on the relevant dimensions of the liner body 200;

[0062] (3) The outer plate body 3021 is manufactured by a stamping and / or cutting process, and a connecting flange is manufactured at the upper end of the outer plate body 3021 by a stretching and / or stamping and / or bending process, and the connecting flange is fixed to the open end of the liner body 200 by an assembly welding process;

[0063] (4) A flanging structure is produced by flanging one side edge of the opening end of the liner body 200 through a stretching and / or stamping and / or bending process;

[0064] (5) After completing steps (3) and (4), the flange structure and the connecting flange are fixedly connected by assembly and / or welding.

[0065] Example 2

[0066] The inner tank body 200 provided in this embodiment 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 / the third splicing component and the first splicing component is located on a plane.

[0067] like Figures 4 to 6As shown, the first splicing component includes a bottom plate 204 of the inner container 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.

[0068] The second splicing component / third splicing component includes a side panel 203 parallel to the stretching direction of the dishwasher. The second splicing component / third splicing component also includes an extension portion connected to the side panel 203 and bent toward the opposite side panel. The extension portion is connected to the first splicing component. The extension portion includes a rounded corner structure between the inner tank wall surfaces. The setting of the extension portion makes the splicing position of the second splicing component / third splicing component and the first splicing component located on a plane.

[0069] The second splicing component / the third splicing component is stamped as a whole, and the extension portion includes a first extension surface 2031 located on the bottom surface of the side panel 203 and a second extension surface 2032 located on the side surface of the side panel 203. After forming the rounded structure between the inner tank wall surfaces, the extension portion continues to extend straight toward the opposite side panel. 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.

[0070] The dishwasher is stretched by a slide rail. In this embodiment, the side panel 203 of the second splicing component / the third splicing component includes a recessed surface 2033. The recessed surface 2033 is a receiving portion recessed toward the center of the inner tank. The receiving portion can be installed with a slide rail to facilitate stretching the dishwasher and taking and placing tableware in the dishwasher.

[0071] The inner liner body 200 described in this embodiment is provided with a recessed surface 2033 for avoiding the slide rail, which is beneficial to the expansion of the inner liner, and recessed surfaces 2033 recessed toward the interior of the inner liner body 200 are provided on the two side plates 203. The recessed surface 2033 has little stretching and does not affect the structural strength of the inner liner.

[0072] Preferably, the concave surface 2033 is formed by punching at the bottom of the side plate 203 facing the interior of the inner container.

[0073] Preferably, the recessed surface 2035 / 2033 includes a horizontal bending surface 20331 formed by first bending the bottom of the side panel 203 from top to bottom toward the inside of the inner tank, and a vertical bending surface 20332 formed by bending the end of the horizontal bending surface 20331 vertically downward, and the horizontal bending surface 20331 and the vertical bending surface 20332 are connected and transitioned by a smooth arc surface.

[0074] Preferably, a first extension surface 2031 that bends and extends toward the bottom plate 204 is provided at the bottom of the vertical bending surface 20332 , and the first extension surface 2031 is connected to the corresponding side of the bottom plate 204 .

[0075] In the above scheme, the bottom edge of the horizontal bending surface 20331 is bent toward the bottom to form the first extension surface 2031. The first extension surface 2031 is preferably in the same plane as the bottom plate 204. In this way, the joint 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 alignment of the splicing parts and moves the welding position to the plane, reducing the difficulty of welding.

[0076] Preferably, second extension surfaces 2032 are respectively provided on both sides of the side panels 203 , which are bent and extended toward the front panel 201 and the rear panel 202 , and the second extension surfaces 2032 are connected to the corresponding front panel 201 or the rear panel 202 .

[0077] In the above scheme, both sides of the side panel 203 are bent toward the front panel 201 and the rear panel 202 to form the second extension surface 2032. The side where the second extension surface 2032 is spliced with the front panel 201 or the rear panel 202 is in the same plane as the front panel 201 or the rear panel 202, thereby avoiding the corners and facilitating welding and fixation.

[0078] In the present invention, the design of the second extension surface 2032 prevents splicing on the recessed surface 2035 / 2033, and the splicing position is transferred to the plane, thereby simplifying the welding process.

[0079] Example 3

[0080] The difference between this embodiment and the second embodiment is that the convex profile 2034 is provided in the middle of the side plate 203 of the inner tank body 200. Figure 7 and Figure 8 As shown, the two side plates 203 are respectively punched outwards of the inner tank body 200 to form a convex pressing profile 2034 , and a concave surface 2035 is formed on the side plate 203 at the bottom of the pressing profile 2034 .

[0081] In this embodiment, the recessed surface 2035 is formed by stamping the side panel 203 with the profiling 2034, leaving the bottom of the side panel 203 with a recessed surface 2035 relative to the profiling 2034. This creates a convex structure, expanding the interior space of the liner. In this embodiment, the recessed surface 2035 differs from the aforementioned recessed surface 2033 in that it has a smaller curvature due to the larger profiling area. A larger curvature of the stamped recessed surface 2035 would have resulted in excessive stretching.

[0082] The middle portion of the side plate 203 is punched toward the outside of the inner container, forming a large-area convex profile 2034 in the middle portion of the side plate 203, thereby facilitating the expansion of the inner container.

[0083] Preferably, the cross-sectional profile of the recessed surface 2035 longitudinally cut through a vertical plane perpendicular to the side panel 203 on which it is located includes, from top to bottom, a first curve 20351 with a center of curvature inside the inner liner and a second curve 20352 with a center of curvature outside the inner liner, and the first curve 20351 and the second curve 20352 have a smooth transition.

[0084] The length of the first curve 20351 is equal to the length of the second curve 20352; the curvature of the first curve 20351 is equal to the curvature of the second curve 20352. Through this structural design, the edge of the press 2034, or the recessed surface 2035, has the same tensile strength at the two bends, and the plate is evenly stretched and has a uniform thickness, thereby preventing local excessive stretching from affecting the quality of the liner.

[0085] Example 4

[0086] like Figure 9 As shown, the structure of the inner liner body 200 provided in this embodiment is provided with a notch on at least one of the two ends at the position of the splicing seam 2014, and the notch is an installation opening 2011 for placing the detergent adding device. The inner liner body 200 is formed by a bottom wall and a side peripheral wall, and the side peripheral wall includes a first splicing portion 2012 and a second splicing portion 2013, and the first splicing portion 2012 and the second splicing portion 2013 are spliced to form the side peripheral wall. The first splicing portion 2012 and / or the second splicing portion 2013 are provided with a notch, and the notch forms the installation opening 2011 for placing the detergent adding device after the first splicing portion 2012 and the second splicing portion 2013 are spliced.

[0087] Specifically, the first splicing portion 2012 includes a first splicing surface formed by vertically connecting the first side and the first bottom edge, and the second splicing portion 2013 includes a second splicing surface formed by vertically connecting the second side and the second bottom edge. The first side and / or the second side are provided with a notch, and 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 in the same horizontal plane. The notch forms an installation port 2011 for placing a detergent adding device when spliced, and the size of the notch can be set to different sizes and shapes according to the size of the detergent adding device.

[0088] For example, a notch may be provided on the first side of the first joining surface, and a notch may be provided at the corresponding position of the second side. When the first joining surface and the second joining surface are joined, the middle notch portion of the first side and the middle notch portion of the second side form an installation opening 2011 for placing a detergent adding device.

[0089] As an alternative to the above solution, a notch may be provided along one side edge of the first or second joining surface. For example, a notch may be provided on the first side edge of the first joining surface. When the first and second joining surfaces are joined, the notch on the first side edge of the first joining surface and the second side edge of the second joining surface form an installation opening 2011 for placing a detergent adding device at the location of the joint 2014. Alternatively, a notch may be provided only on the second side edge of the second joining surface.

[0090] In this embodiment, an installation port 2011 for placing a detergent adding device is formed at the position of the joint seam 2014, which reduces the length of the weld and can even eliminate the middle weld, which not only reduces the number of welding steps but also saves costs.

[0091] In this embodiment, the bottom wall has an upwardly open accommodating space, and the open end of the bottom wall is connected to the bottom edge of the side wall to form the inner liner body 200. The bottom edge of the side wall is located above the water level in the inner liner body 200 to prevent water leakage.

[0092] Furthermore, a fixing plate is provided at the installation opening 2011 , and the fixing plate is located outside the inner tank body 200 . The detergent adding device is fixedly connected to the fixing plate by screws, thereby fixing the detergent adding device to the inner tank body 200 .

[0093] Preferably, a rubber ring or other sealing structure that matches the shape and size of the mounting opening 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 .

[0094] In this embodiment, the side wall is formed by bending and splicing at least one rectangular stainless steel sheet metal member. One end of the sheet metal member serves as a first splicing surface of the first splicing portion 2012, and the other end serves as a second splicing surface of the second splicing portion 2013. The side wall can also be formed by bending and splicing two or more stainless steel sheet metal members. In this embodiment, the side wall is formed by bending a single stainless steel sheet metal member.

[0095] Specifically, the rectangular plate is bent four times to form the side wall of the inner liner. When the two ends of the plate are spliced, the inner surfaces are flush to form the front wall of the inner liner body 200. The splicing seam 2014 is located on the front wall surface of the inner liner. The splicing seam 2014 of the side wall of the inner liner in this embodiment is located on a plane, which avoids special-shaped welding, reduces the difficulty of welding, and effectively prevents the problem of cracking easily caused by stretching of the stainless steel inner liner. In addition, notches are opened at both ends, and the notches form an installation port 2011 for placing a detergent adding device at the position of the splicing seam 2014, which reduces the length of the splicing seam 2014 and reduces the welding process.

[0096] In this embodiment, the joint of the first joint portion 2012 and the second joint portion 2013 is fixed by the following three overlapping methods:

[0097] First way:

[0098] See also Figure 10 As shown, in another embodiment, a first connecting surface 250 is provided on one side of the spliced edge where the first splicing portion 2012 and the second splicing portion 2013 meet, and a second connecting surface 251 is provided on the corresponding side of the second splicing portion 2013, which is bent and extended toward the exterior of the inner liner. The second connecting surface 251 is longer than the first connecting surface 250. After the first and second connecting surfaces 250 and 251 are bonded, the portion of the second connecting surface 251 that is longer than the first connecting surface 250 is bent toward the other side of the first connecting surface 250, forming a three-layer bonding surface. The three-layer bonding surface is bent toward and bonded to the outer surface of any spliced portion. In this embodiment, a three-layer bonding surface is formed, the overlapping structure is relatively stable, and there are no protruding end surfaces, which will not damage other components.

[0099] Second way:

[0100] See also Figure 11 As shown, in another embodiment, the first connecting surface 250 and the second connecting surface 251 are both formed by vertically bending the edges of the first splicing portion 2012 and the second splicing portion 2013.

[0101] Preferably, the first connecting surface 250 and the second connecting surface 251 are welded and fixed after being attached to each other;

[0102] Preferably, the first connecting surface 250 and the second connecting surface 251 are of equal length, and both lengths are very small so as not to affect the installation space of the dishwasher inner tank. In addition, the first connecting surface 250 and the second connecting surface 251 are of equal length, and the end surface formed after welding is wide, which is not easy to cause cuts to the external structure.

[0103] The third way:

[0104] See also Figure 12 As shown, one side edge of the splicing of the first splicing part 2012 and the second splicing part 2013 is formed with a first connecting surface 250 that is recessed toward the outside of the inner liner body 200, and the second splicing surface of the second splicing part 2013 is a second connecting surface 251. The surface on the corresponding side of the first connecting surface 250 is attached to the surface on the corresponding side of the second connecting surface 251.

[0105] In the above solution, in two adjacent splicing components, the edge of the first splicing portion 2012 is recessed to form the first connecting surface 250 , while the second splicing portion 2013 remains unchanged, and the first connecting surface 250 is directly overlapped on the second splicing portion 2013 .

[0106] Preferably, the edge of the first splicing part 2012 is first bent toward the side away from the inner liner body 200 to form a bending section 252, and the bending section 252 is bent again to form a first connecting surface 250 parallel to the outer surface of the second splicing part 2013. The height of the bending 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 parts transition smoothly, thereby making the inner wall surface of the inner liner body 200 flat.

[0107] This embodiment adopts an overlapping method, and the size of the front wall can be adjusted by adjusting the overlapping length to meet the needs of different sizes and eliminate the impact of processing errors.

[0108] Example 5

[0109] See also Figure 13 As shown, the difference of the dishwasher inner tank of this embodiment is that it includes a bottom plate 204 and a side panel assembly. The bottom plate 204 and the side panel assembly are an integrated piece, and the side panel assembly is bent and spliced to form the side wall of the dishwasher.

[0110] In the above solution, the inner liner is formed by bending an integral plate, which reduces the length of the weld and simplifies the processing technology.

[0111] Preferably, the bottom plate 204 has multiple edges, and the side plate assembly includes plate bodies respectively connected to the edges of the bottom plate 204, and the plate bodies are bent toward the same side of the bottom plate 204 to form the side wall of the dishwasher.

[0112] In the above solution, through the solution of the present invention, inner containers of different shapes can be manufactured respectively, and each plate is bent relative to the bottom plate 204, and two adjacent plates are spliced together to form the side wall of the annular dishwasher.

[0117] In the above solution, through the design of the flange structure, two adjacent plates can be fitted and positioned, which is convenient for fixation by welding, and the flange has left and right support and limitation functions for the other plate, which facilitates the welding process.

[0118] The flange is formed by bending the edge of a plate toward the plane of the adjacent plate. When the inner container comprises four plates, the flange is formed by bending the edge of the plate vertically. The bending direction can be toward the side of the adjacent plate or away from the side of the adjacent plate.

[0119] Preferably, the inner liner includes two first plates 8001 arranged on opposite sides of the bottom plate 204, and the other two plates of the inner liner are second plates 8002. The bottoms of the two first plates 8001 are provided with recessed surfaces 2033 / 2035 extending along the length direction of the plates and recessed in the direction of bending of each plate. The first plates 8001 are provided with flanges on both sides. After each plate is bent relative to the bottom plate 204, the edges on both sides of the two second plates 8002 are attached to the flanges.

[0120] Preferably, the contour lines of the edges of the second plate 8002 on both sides match the longitudinal cross-sectional profile of the first plate 8001. In this way, after the second plate 8002 is connected to the flange of the first plate 8001, the edges are uniform without protruding parts.

[0121] Preferably, the first plate body 8001 is stamped on one side connected to the bottom plate 204 to form a recessed surface 2033 / 2035 that gradually narrows toward the bottom plate 204 and is connected to the bottom plate 204; the second plate body 8002 is stamped on one side connected to the bottom plate 204 to form a recessed surface 2033 / 2035 that gradually narrows toward the bottom edge and is connected to the bottom plate 204; after each plate body is bent, the edges of the recessed surfaces 2033 / 2035 of the two adjacent plates are in contact and connected accordingly. In the above scheme, recessed surfaces 2033 / 2035 are also set on the two second plates 8002 corresponding to the recessed surfaces 2033 / 2035 on the first body. The recessed surface 2033 / 2035 of the first plate 8001 is connected to the recessed surface 2033 / 2035 of the second plate 8002, and the planes on the top of the recessed surfaces 2033 / 2035 of the two are also connected accordingly, thereby avoiding the connection between the two adjacent plates through the arc surface and the plane, and simplifying the splicing process.
