[0062] Example 6

[0063] like Figure 7 As shown, this embodiment provides a dishwasher inner tank body 200, including a bottom plate 204 and a side plate assembly. The bottom plate 204 and the side plate assembly are an integrated piece, and the side plate assembly is bent and spliced ​​to form the side wall of the dishwasher.

[0081] Preferably, in step S1 , a concave surface 2033 is punched out on the bottom of the two plates on both sides of the bottom plate 204 along the bending direction of the plates.

[0082] Alternatively, in step S1 , a convex profile is punched on the two plates on both sides of the bottom plate 204 toward the side opposite to the bending direction of the plate, and the concave surface 2035 is formed between the bottom surface of the profile and the bottom edge of the plate.

[0083] Example 7

[0084] like Figure 8As shown, this embodiment provides an inner tank structure for use in a dishwasher, including an inner tank body 200, wherein the inner tank body 200 is formed by a bottom wall and a side peripheral wall, wherein the side peripheral wall includes a first splicing portion 2012 and a second splicing portion 2013, wherein the first splicing portion 2012 and the second splicing portion 2013 are spliced ​​together to form the side peripheral wall, and a notch is provided on the first splicing portion 2012 and / or the second splicing portion 2013, wherein the notch forms an installation port 2011 for placing a detergent adding device after the first splicing portion 2012 and the second splicing portion 2013 are spliced ​​together.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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 .

[0091] 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 .

[0092] 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.

[0093] 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.

[0094] The joint of the first joint portion 2012 and the second joint portion 2013 of the present invention is fixed by the following three overlapping methods:

[0095] First way:

[0096] See also Figure 9 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.

[0097] 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 .

[0098] 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.

[0099] Second way:

[0100] See also Figure 10 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 11 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.

[0105] The present invention adopts an overlapping manner, 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 influence of processing errors.
