Description

Technical Field

[0001] This invention belongs to the field of dishwasher technology, specifically, it relates to a dishwasher inner tank structure. Background Technology

[0002] Existing dishwasher stainless steel inner tanks are typically manufactured using a one-piece stretching process. Structurally, this method suffers from poor consistency in the stretched structure, with some rounded corners prone to deformation, and significant challenges in controlling the overall dimensions of the inner tank. From a materials and processing perspective, the thickness of the stainless steel inner tank material is related to the stretching depth; the deeper the stretch, the thicker the material required. Furthermore, stretching can lead to uneven inner tank wall thickness, and deep stretching is difficult and inefficient. Therefore, developing a simple and reliable stainless steel inner tank forming process has been a long-standing goal for those skilled in the art.

[0003] Chinese Patent Application No. 201711315440.6 discloses a novel dishwasher inner liner and its molding process. The dishwasher inner liner includes a base plate, on which a side wall assembly for assembling the inner liner's perimeter is provided. The side wall assembly includes four side walls disposed around the perimeter of the base plate; at least one side wall forms a first component with the base plate, and the remaining side walls form a second component. The second component and the first component are assembled to form the dishwasher inner liner. In this disclosed dishwasher inner liner, the base plate is a horizontal plate, making it difficult for water inside the inner liner to collect and drain.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a dishwasher inner tank structure. The bottom wall of the dishwasher inner tank provided by this application is in a converging shape towards the bottom of the inner tank, which facilitates the collection of water flow inside the inner tank.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

The inner container main body 200 is an open upward dishwasher inner container structure. In order to facilitate the assembly and use of the dishwasher, a bottom cover 400 and a bottom support 500 are provided on the bottom wall of the inner container. The bottom support 500 plays a supporting and fixing role for 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, an outer plate 302 is provided 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 main body 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, a door body 301 is provided on the dishwasher. The inner container main body 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 main body 200, and at the same time connected to the door body 301 and the bottom support 500.

[0075] The structure characteristics of the inner container body 200 are described below through Examples 1 to 4

[0076] Example 1

[0077] The inner container body 200 provided in this example is composed of two spliced components, which is simple in structure and simple in manufacturing process, greatly reducing the welding process in the manufacturing process of the dishwasher and improving the assembly efficiency. As shown in Figure 2 and Figure 3 , the inner container body 200 in this example includes an inner container bottom wall 210 and an inner container peripheral wall 220, the inner container bottom wall 210 and the inner container peripheral wall 220 form an inner container body 200 with an opening upward, and the inner container peripheral wall 220 is a plate piece which is bent and rolled into a ring shape, one end of the plate piece has a splicing part 221, the other end is overlapped on the splicing part 221, and the splicing positions 222 of the two ends are located on the plane, which eliminates the influence of dimensional error on the assembly structure, facilitates the welding of the spliced components with the final size, the weld is regular, the welding plane processing process is simple, and the manufacturing efficiency of the dishwasher is improved.

[0078] As shown in Figure 3 , the splicing part 221 is a bending structure formed by bending one end of the plate piece, the end of the bending structure is parallel to the other end 2211 of the plate piece, and 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 piece 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 piece.

[0079] As shown in Figure 2 , the side surface of the first extension structure 2213 close to the inner center of the inner container is attached to the side surface of the other end 2211 of the plate piece away from the inner center of the inner container, and is integrally connected.

[0080] The inner wall surface of one end of the plate piece before bending is flush with the inner wall surface of the other end 2211 of the plate piece.

[0081] The perpendicular distance of the first bending structure 2212 bent outward of the inner container is equal to the thickness of the plate piece, and the inner wall surface of one end of the plate piece before bending is flush with the inner wall surface of the other end 2211 of the plate piece.

[0082] The end surface of the other end 2211 of the plate piece is attached to the bending surface of the first bending structure 2212.

[0083] The end surface of the other end 2211 of the plate piece has a gap with the bending surface of the first bending structure 2212.

[0084] The gap between the end face of the other end 2211 of the plate and the bending face of the first bending structure 2212 is filled with welding material, sealing strip or blocking rib.

[0085] As shown in the drawings, Figure 2 The inner container peripheral wall 220 comprises four straight side plates, and the straight side plates are connected by rounded transition side plates.

[0086] As shown in the drawings, Figure 4 The bottom wall 210 of the inner container is connected to the top face of the connecting side wall 211.

[0087] As shown in the drawings, Figure 5 And Figure 6 The dishwasher is stretched through a slide rail, and the connecting side wall 211 connected to the bottom plate 204 of the inner container and parallel to the stretching direction of the dishwasher is provided with a recessed accommodation part recessed towards the center of the inner container.

[0088] The recessed face 2033 comprises a horizontal bending face 20331 formed by bending the connecting side wall 211 upwards towards the inside of the inner container, a vertical bending face 20332 formed by vertically bending the end of the horizontal bending face 20331 downwards, and a smooth arc surface connecting the horizontal bending face 20331 and the vertical bending face 20332.

[0089] Preferably, the bottom of the vertical bending face 20332 is bent and extended towards the side edge of the bottom plate 204 corresponding to the bottom plate 204.

[0090] In the present application, the inner container of the dishwasher is divided into multiple splicing components, and the splicing components are spliced to form the inner container of the dishwasher.

[0091] Preferably, the lap joint structure comprises a first connecting face 250 provided on one of the two adjacent splicing components and a second connecting face 251 provided on the other splicing component, and the first connecting face 250 and the second connecting face 251 are connected by surface-to-surface lapping.

[0092] In the above scheme, the lap joint structure is connected by surface-to-surface lapping, which is beneficial for the splicing and positioning of the splicing components.

[0093] Preferably, in the two adjacent splicing components, one splicing component is provided with a first connecting surface 250 extending to the outside of the inner container by bending inwardly at one side edge, and the other splicing component is provided with a second connecting surface 251 extending to the outside of the inner container by bending inwardly at the corresponding side edge, and the first connecting surface 250 and the second connecting surface 251 are connected by lamination.

[0094] 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.

[0095] Referring to Figure 7 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 perpendicularly.

[0096] Preferably, the first connecting surface 250 and the second connecting surface 251 are welded and fixed after lamination;

[0097] 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 injury to the external structure.

[0098] Referring to Figure 8 In another scheme, in the two adjacent splicing components, one splicing component is provided with a first connecting surface 250 extending to the outside of the inner container by bending inwardly at one side edge, and the other splicing component is provided with a second connecting surface 251 extending to the outside of the inner container by bending inwardly at the corresponding side edge, and the second connecting surface 251 is longer than 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, and the three-layer laminated surface 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, the lap joint structure is more stable, and there is no protruding end face, which will not damage other components.

[0099] Referring to Figure 9 In another scheme, in the two adjacent splicing components, one splicing component is provided with a first connecting surface 250 formed by recessing to one side of the outer surface of the inner container at one side edge, and the other splicing component is provided with a second connecting surface 251 at the corresponding side edge, and the corresponding side edge of the splicing component is laminated to the first connecting surface 250.

[0100] 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.

[0101] 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.

[0102] In this embodiment, the bottom wall 210 of the inner liner is the first splicing component, and the peripheral wall 220 of the inner liner is the second splicing component. A first connecting surface 250 is provided on the splicing edge of the bottom wall 210 or the peripheral wall 220 of the inner liner, and a second connecting surface 251 is provided on the edge of the peripheral wall 220 or the bottom wall 210 of the inner liner. The first connecting surface 250 and the second connecting surface 251 are connected.

[0103] The inner liner bottom wall 210 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.

[0104] Example 2

[0105] like Figure 9 As shown, the structure of the inner liner body 200 provided in this embodiment differs from that in Embodiment 1 in 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.

[0106] like Figure 10 As shown, this embodiment includes an inner liner body 200, which is formed by an inner liner bottom wall 210 and an inner liner peripheral wall 220. The inner liner peripheral wall 220 includes a first splicing part 2012 and a second splicing part 2013. The first splicing part 2012 and the second splicing part 2013 are spliced ​​together to form a side peripheral wall. The first splicing part 2012 and / or the second splicing part 2013 are provided with a notch. After the first splicing part 2012 and the second splicing part 2013 are spliced ​​together, the notch forms an installation port 2011 for placing a detergent adding device.

[0107] Specifically, the first splicing part 2012 comprises a first splicing surface formed by the vertical connection of a first side edge and a first bottom edge, and the second splicing part 2013 comprises a second splicing surface formed by the vertical connection of a second side edge and a second bottom edge. The first side edge and / or the second side edge is provided with an opening. The first side edge of the first splicing surface and the second side edge 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. The opening forms a mounting opening 2011 for placing the detergent adding device when splicing. The size of the opening can be set to different sizes and shapes according to the size of the detergent adding device.

[0108] For example, the first side edge of the first splicing surface is provided with an opening, and the second side edge is provided with an opening at a corresponding position. When the first splicing surface and the second splicing surface are spliced, the middle opening part of the first side edge and the middle opening part of the second side edge form the mounting opening 2011 for placing the detergent adding device.

[0109] As an alternative to the above-mentioned scheme, an opening can also be formed along one side edge of the first splicing surface or the second splicing surface. For example, an opening can be formed on one side edge of the first splicing surface. When the first splicing surface and the second splicing surface are spliced, the opening part of the first splicing surface and the splicing position 222 of the second splicing surface form the mounting opening 2011 for placing the detergent adding device. An opening can also be formed on one side edge of the second splicing surface.

[0110] The mounting opening 2011 for placing the detergent adding device is formed at the splicing position 222 in this embodiment, which reduces the length of the weld seam and even eliminates the middle weld seam. This not only reduces the welding process, but also saves costs.

[0111] Further, a fixing plate is arranged at the mounting opening 2011. The fixing plate is located outside the inner container main body 200. The detergent adding device is fixedly connected to the fixing plate by screws, and thus is fixed to the inner container.

[0112] More preferably, a rubber ring or other sealing structure matching the shape and size of the mounting opening 2011 is arranged between the fixing plate and the detergent adding device, for increasing the sealing between the detergent adding device and the inner container main body 200.

[0122] In the above scheme, the bottom edge of the horizontal bending surface 20331 is bent to form the first extending surface 2031, which is preferably in the same plane as the bottom plate 204. In this way, the position where the bottom plate 204 and the lower edge of the side plate 203 are spliced is in the plane, not at the corner, which facilitates the splicing and alignment of the spliced parts, and moves the welding position to the plane, reducing the difficulty of welding.

[0133] Different from the above-mentioned embodiments, in the embodiment, the inner container main body 200 is formed by splicing a polygonal plate, and the forming manner is as follows.

[0134] As shown in Figure 13 to Figure 15 , the inner container main body 200 in the embodiment includes a bottom plate 204 and a side plate assembly, the bottom plate 204 and the side plate assembly are an integral piece, and the side plate assembly is formed by bending and splicing to surround the side wall of the dishwasher.

[0135] In the above-mentioned scheme, the inner container is formed by bending an integral plate, so that the length of the weld is reduced, and the processing technology is simplified.

[0136] Preferably, the bottom plate 204 has a plurality of edges, the side plate assembly includes plate bodies respectively connected to the edges of the bottom plate 204, and the plate bodies are bent towards the same side of the bottom plate 204 to jointly surround the side wall of the dishwasher.

[0137] In the above-mentioned scheme, different shapes of inner containers can be respectively manufactured by the scheme of the present application, the plate bodies are bent relative to the bottom plate 204, and the adjacent two plate bodies are spliced to form the annular side wall of the dishwasher.

[0138] Preferably, the bottom plate 204 is a quadrilateral plate, the quadrilateral plate is respectively connected to four plate bodies at four edges, the four plate bodies are bent towards the same side of the bottom plate 204 to surround the side wall of the dishwasher, and the opposite side edges of the adjacent two plate bodies are in contact and connected by a set process.

[0142] In the above scheme, through the design of the flange structure, the two adjacent plate bodies can be attached and positioned, which facilitates welding fixation, and the flange has left and right support and limiting functions for the other plate body, thereby facilitating the welding process.

[0143] Preferably, the flange is formed by bending the edge of the plate body towards the plane on which the adjacent plate body is located. When the inner container comprises four plate bodies, the flange is formed by bending the edge of the plate body vertically. The bending direction can be towards the side of the plate body to be spliced, or away from the side of the plate body to be spliced.

[0144] Preferably, the inner container comprises two first plate bodies 8001 arranged on opposite sides of the bottom plate 204, and the other two plate bodies of the inner container are second plate bodies 8002. The bottom of the first plate body 8001 is provided with a recessed surface 2033 / 2035 extending along the length direction of the plate body and recessed towards the bending direction of the plate body. The flange is arranged on the side edge of the first plate body 8001, and after the plate bodies are bent relative to the bottom plate 204, the side edges of the two second plate bodies 8002 are attached to the flanges.

[0145] Preferably, the contour line of the side edge of the second plate body 8002 matches the longitudinal cross-sectional profile of the first plate body 8001. In this way, after the flange of the second plate body 8002 is connected to the first plate body 8001, the side edge is uniform and does not have protruding parts.

[0147] The following provides a manufacturing method of the dishwasher inner container, comprising the following steps:

[0148] S1, punching out an integrated bottom plate 204 and side plate assembly on the plate according to the size of the inner container;

[0149] S2, bending each plate body in the side plate assembly to form the side wall of the dishwasher;

[0150] S3, connecting and fixing each plate body through a connection process.

[0151] Preferably, a quadrilateral bottom plate 204 and four plate bodies respectively connecting the four edges of the bottom plate 204 are punched out on the plate, each plate body is vertically bent towards the same side of the bottom plate 204, so that each plate body is spliced to form the side wall of the dishwasher, and the two opposite side edges of the adjacent two plate bodies are welded.

[0152] Preferably, in step S1, a recessed surface 2033 is punched out on the bottom of the two plate bodies on both sides of the bottom plate 204 along the direction of plate body bending.

[0153] Alternatively, in step S1, an outwardly convex outer convex profile is punched out on the two plate bodies on both sides of the bottom plate 204 respectively towards the side opposite to the plate body bending direction, and the recessed surface 2035 is formed between the bottom surface of the outer convex profile and the plate body bottom edge.

[0154] The specific structural features of the inner container main body 200 will be described below through Examples 5 to 8.

[0155] Example 5

[0156] Referring to Figure 15 In this embodiment, the side plate 203 is provided with an outwardly convex structure protruding from the inside to the outside of the inner container, and the provision of the outwardly convex structure increases the capacity of the inner container, realizing the expansion of the inner container.

[0157] Preferably, the inner container is slidably arranged in the shell or support of the dishwasher, the side plate includes two side plates arranged along the sliding direction of the inner container, and the two side plates are arranged as outwardly convex structures protruding away from the opposite side plate, thereby increasing the size of the inner container in a direction perpendicular to the sliding direction of the inner container and increasing the inner space of the inner container.

[0158] In the above scheme, the inner container main body 200 includes a front plate 201, a rear plate 202, side plates 203 oppositely arranged on both sides of the front plate, and a rounded transition side plate respectively connecting the front plate 201 / rear plate 202 and the side plate 203, and the outwardly convex structure of the side plate is obtained by punching and profiling a large area in the middle of the side plate 203, forming a structure with the middle part protruding and the peripheral wall retracting, thereby increasing the inner space of the inner container. Specifically, the outwardly convex profile 2034 is punched out on the side plate in the direction opposite to the opposite side plate, forming a shell structure with the bottom wall protruding outwardly and the peripheral wall extending towards the side of the opposite side plate. In this way, a large area in the middle of the side plate is punched, thereby increasing the inner space of the inner container.

[0159] Preferred, such as Figure 5 As shown, 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 liner. The two sides of the outwardly convex pressing type 2034 are smoothly connected to the rounded transition side plates between the front / rear plate and the side plate through the first arc surface 207. The middle part of the outwardly convex pressing type 2034 is stamped into a convex plane. The plane of the outwardly convex pressing type 2034 transitions to the rounded transition side plate through the first arc surface 207. This results in low stamping strength on the side plate, high strength and good quality of the inner liner, and the smooth transition of the inner liner results in a good overall gloss and beautiful appearance.

[0160] After the side plate 203 is formed by the outward convex pressing 2034, a recessed surface 2035 is formed at the bottom of the side plate 203 that is recessed into the inner tub. The recessed surface 2035 is used to avoid the slide rail of the dishwasher.

[0161] In the above solution, the inner liner is formed with a recessed surface for installing the dishwasher slide rails, thereby making full use of the space inside the dishwasher shell and facilitating the expansion of the inner liner.

[0162] Preferably, the recessed surface includes a recessed surface that gradually recedes into the inner liner from top to bottom and a vertical surface extending downward from the end of the recessed surface. The cross-sectional profile of the recessed surface, longitudinally cut by the vertical surface perpendicular to its side plate, includes, from top to bottom, a first curve 20351 with its center of curvature inside the inner liner and a second curve 20352 with its center of curvature outside the inner liner. The first curve and the second curve have a smooth 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 20351 is equal to the curvature of the second curve 20352. Through this structural design, the edge of the outwardly convex pressing type 2034, or the two bends of the recessed surface 2035, has the same tensile strength, the plate is stretched uniformly, and the thickness is uniform, thereby preventing local overstretching from affecting the quality of the inner liner.

[0163] See Figure 5 As shown, in another structure, the recessed surface is formed by directly stamping the bottom of the side plate into the inner liner. The recessed surface includes a horizontally bent surface 20331 formed by bending the bottom wall of the side plate 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 and the vertically bent surface are connected by a smooth arc surface. In this embodiment, the recessed surface is indirectly formed by the outward convex stamping pattern. Because the stamping pattern is large, it cannot be stamped with high strength, therefore it does not have a horizontally bent surface. Figure 16 Because it is a directly stamped concave surface with a small stamping area, it can stamp out concave surfaces with both horizontal and vertical bending surfaces.

[0164] See Figure 1As shown, the upper part of the convex pressing type 2034 is connected with the top edge of the side plate 203 by a third arc surface 800, which is gradually narrowed towards the inner container axis from bottom to top, and the narrowed part is recessed towards the inner container, which has the function of blocking the washing water sprayed upwards. One outer convex pressing type 2034 realizes multiple structural functions.

[0165] Further, the front plate 201 and the rear plate 202 of the inner container can also be similar to the two side plates 203, and are provided as an outer convex structure towards the outside of the inner container to realize the expansion of the inner container. The structure can be similar to the above-mentioned two side plates 203, and will not be described again.

[0166] Embodiment six

[0167] In this embodiment, the bottom wall 210 of the inner container body 200 is in a folding shape that is folded towards the bottom of the inner container, which is convenient for the water flow in the inner container body 200 to collect, and at the same time, the reinforcing ribs are formed by stamping to enhance the structure of the inner container itself.

[0168] Participation Figure 17 , Figure 19 , Figure 18 As shown, the inner container structure provided in this embodiment includes a bottom wall 210 and a peripheral wall 220, the peripheral wall 220 includes a front plate 201 and a rear plate 202 and two side plates 203, the lower edge of the peripheral wall 220 is circumferentially arranged around the outer edge of the bottom wall 210 to form a top-open containing cavity, and the bottom wall 210 is arranged to be inclined downward along the lower edge of the peripheral wall 220 to form a folding shape that is folded towards the bottom of the inner container, which is convenient for the water flow in the inner container body 200 to collect downward.

[0169] Further, as shown in Figure 18 , a through hole 2041 is formed in the bottom wall 210 of the inner container, the through hole 2041 is located below the plane where the lower edge of the peripheral wall 220 is located, and the through hole 2041 and the plane where the lower edge of the peripheral wall 220 is located form a certain height difference, which is convenient for the water flow to be discharged downward, and the bottom wall 210 is arranged to be inclined downward along the lower edge of the peripheral wall 220 towards the direction of the through hole 2041, and the bottom wall 210 is in a folding shape that is folded from the lower edge of the peripheral wall 220 towards the direction of the through hole 2041, which is convenient for the water flow in the inner container to collect and discharge through the through hole 2041.

[0170] In this embodiment, the bottom wall 210 includes four flat surfaces 2042 that are respectively arranged to be inclined between the lower edge of the peripheral wall 220 and the through hole 2041, the flat surfaces 2042 arranged to be inclined downward and the flat surfaces 2042 form four reinforcing ribs therebetween, which enhances the structure of the inner container itself.

[0171] More preferably, the bottom wall 210 comprises a flat surface 2042 and a transition curved surface 2043 arranged obliquely between the lower edge of the peripheral wall 220 and the through hole 2041, respectively, and the transition curved surfaces 2043 and the flat surfaces 2042 are arranged in intervals to form the inner container bottom wall 210.

[0172] In the embodiment, the through hole 2041 can be located at any position of the bottom wall 210, but in order to increase the overall aesthetics of the inner container body 200 and to enable the accumulated water in the inner container to be discharged in time, more preferably, the through hole 2041 is arranged at the center position of the bottom wall 210, the transition curved surface 2043 can be located at the center line position of the bottom wall 210, the through hole 2041 is a center hole located at the intersection position of the center line of the bottom wall 210, and the flat surface 2042 is located between two adjacent transition curved surfaces 2043.

[0173] As a more preferred scheme of the above scheme, the transition curved surface 2043 is located at the diagonal position of the inner container bottom wall 210, the through hole 2041 is a center hole located at the intersection position of the diagonal of the bottom wall 210, and the flat surface 2042 is located between two adjacent transition curved surfaces 2043. The transition curved surface 2043 arranged between two adjacent flat surfaces 2042 can prevent some sundries from being trapped between the gaps due to the too small included angle between the two adjacent flat surfaces 2042, which is not convenient for cleaning and pollutes the inner space of the dishwasher.

[0174] Specifically, as shown in FIG. 4, the transition curved surface 2043 is arranged at the diagonal position of the inner container bottom wall 210, the through hole 2041 is a center hole located at the intersection position of the diagonal of the bottom wall 210, and the flat surface 2042 is located between two adjacent transition curved surfaces 2043. Figure 19 to Figure 24As shown, the flat surface 2042 is trapezoidal in shape, and the trapezoid includes a waist 20423, an upper long side 20421, and a lower short side 20422. The lower short side 20422 is an arc shape that is concave towards the upper long side 20421. The transition surface 2043 includes a right-angled side 20431, an arc-shaped side 20432 recessed towards the right-angled side 20431, and two straight sides 20423 connecting the two ends of the right-angled side 20431 and the two ends of the arc-shaped side 20432. A smooth curved surface protruding outward from the bottom of the inner tank is connected between the two straight sides 20423. The distance between the two ends of the right-angled side 20431 is greater than the distance between the two ends of the arc-shaped side 20432. The arc length of the transition surface 2043 gradually increases along the direction away from the through hole 2041, forming a fan-shaped groove-shaped transition surface 2043, which can collect water flow over a larger area. Furthermore, the arc-shaped side 20432 and the short side 20422 of the bottom have the same arc. The right angle of the right-angled side 20431 is located at the apex of the bottom wall 210, and the two sides of the right-angled side 20431 form part of the outer edge of the bottom wall 210. The waist 20423 of the flat surface 2042 and the straight edge 20423 of the transition surface 2043 are connected as one unit. The two right-angled edges 20431 of the transition surface 2043 and the upper long edge 20421 of the flat surface 2042 form the outer edge of the bottom wall 210. The arc-shaped edge 20432 and the lower short edge 20422 are connected as one unit to form a through hole. The transition surface 2043 added between the two flat surfaces 2042 forms eight reinforcing ribs, which is four more than the direct connection between the two flat surfaces 2042 and the flat surface 2042, thus enhancing the strength and rigidity of the inner liner structure.

[0175] In this embodiment, the through hole 2041 can be circular, elliptical, or square. In this embodiment, the through hole 2041 is circular as an example. The bottom wall 210 in this embodiment is integrally formed by stamping a square or rectangular plate. The plate is stamped towards the center to form four flat surfaces 2042 symmetrical along the diagonal direction. Four reinforcing ribs are formed at the diagonal position to increase the strength of the inner liner. The through hole 2041 is opened at the center of the plate. The through hole 2041 can not only be used to drain the water accumulated in the inner liner, but also to install a spray device.

[0176] Furthermore, at the junction of two adjacent flat surfaces 2042, a smooth curved surface protruding outward from the bottom of the inner liner is formed by stamping, forming a transition surface 2043. Two reinforcing ribs are formed at the connection between the transition surface 2043 and the flat surface 2042, which further enhances the strength and rigidity of the inner liner structure. The arc length of the transition surface 2043 gradually increases along the direction away from the through hole 2041, which facilitates the collection of more water flow. Compared with the flat surface 2042, the transition surface 2043 can slow down the water flow speed, prevent splashing, and facilitate collection.

[0177] In another scheme, a transition curved surface 2043 can be formed between two adjacent flat surfaces 2042 by a chamfering machine, and by adjusting the chamfering angle of the chamfering machine, the arc length of the chamfered structure gradually decreases along the direction close to the through hole 2041, so that the transition curved surface 2043 forms a converging shape gradually narrowing in the direction of the through hole 2041, facilitating the gradual convergence of water flow. The transition curved surface 2043 formed by chamfering can strengthen the structure of the inner container itself, and the transition curved surface 2043 has a groove-shaped accommodating space, facilitating flow guide.

[0178] The bottom wall 210 of the dishwasher inner container provided by the present application is integrally formed by stamping, simple in structure, easy to manufacture, and improving production efficiency. The radiating four-sided prismatic bottom wall 210 formed by stamping not only strengthens the structure of the inner container itself, but also facilitates the convergence of water flow to the middle.

[0179] As a variant of the present embodiment, the bottom wall 210 is formed by tilting downward a plurality of plate pieces toward the position of the through hole 2041 of the bottom wall 210, and a plurality of fillets are formed at the splicing position. The plate pieces are smoothly spliced between them, and the arc length of the fillets gradually increases along the direction away from the through hole 2041. Specifically, the bottom wall 210 is formed by splicing four plate pieces symmetrical along the diagonal line of the bottom wall 210 toward the through hole 2041, and the edges of the plate pieces form radiating ribs at the diagonal line position of the bottom wall 210, facilitating the convergence of water flow.

[0180] Embodiment Seven

[0181] When the dishwasher is in cleaning work, a sprayer for cleaning tableware is arranged in the inner container main body 200, and the sprayer includes a spraying arm with a plurality of spraying holes. The spraying arm rotates or swings in the horizontal plane under the drive of the motor. During the rotation or swinging of the spraying arm of the sprayer, the bottom wall 210 or the peripheral wall 220 of the inner container main body 200 may hinder the movement of the spraying arm of the sprayer, so that the spraying range is limited, resulting in poor washing effect and incomplete cleaning of the dishwasher.

[0182] In order to solve the above problems, the present embodiment is based on embodiment six, and an avoiding structure 2003 for avoiding the spraying arm of the dishwasher inner sprayer is arranged in the inner container main body 200.

[0183] In combination Figure 24As shown, the inner container structure of the dish washing machine provided in the embodiment comprises an inner container body 200, which comprises a bottom wall 210 and a peripheral wall 220; further comprises a sprayer, which is installed at the bottom of the inner container body 200, specifically, the sprayer is installed at the position of the through hole 2041 of the bottom wall 210, and the bottom of the inner container body 200 is provided with an avoiding structure 2003 for avoiding the sprayer.

[0184] As shown in the drawings, Figure 19 As shown in the embodiment, the bottom wall 210 and the peripheral wall 220 are connected through the connecting side wall 211, the outer edge of the bottom wall 210 is upwardly folded to the connecting side wall 211, the bottom wall 210 forms an opening upwardly having a small containing cavity structure, the connecting side wall 211 comprises an inner container bottom front wall 2111 close to the door body 301 side and an inner container bottom side wall located on both sides of the inner container bottom front wall 2111, and the inner container bottom side wall comprises an inner container bottom left wall 2112 and an inner container bottom right wall 2113.

[0185] In the embodiment, the avoiding structure 2003 is a profiled structure arranged at the bottom of the inner container body 200, the profiled structure is a recessed surface arranged at the junction of the bottom wall 210 and the inner container bottom side wall and recessed to the outside of the inner container body 200, and the position height of the profiled structure can be determined according to the height of the spraying arm and can be arranged at the junction of the bottom wall 210 and the inner container bottom side wall or on the inner container bottom side wall or the peripheral wall 220.

[0186] The recessed surface formed by stamping and recessed to the outside of the inner container body 200 not only plays a role of avoiding the spraying arm of the sprayer, but also plays a role of expanding the capacity. As shown in the drawings, Figure 21 and Figure 23 As shown, the profiled structure is arranged at the midline end point position of the opposite edges of the bottom wall 210, the profiled structure expands the capacity outwardly to avoid the spraying arm of the sprayer, thereby expanding the spraying range and avoiding the dead angle in the spraying process.

[0187] In the above scheme, the bottom wall 210 can be square, and the profiled structure is arranged at the midpoint of the intersection line at the connection between the four edges of the square bottom wall 210 and the peripheral wall 220. The bottom wall 210 can also be rectangular. The embodiment is described by taking the bottom wall as rectangular. Specifically, the outer edge of the bottom wall 210 includes two opposite long edges and two short edges. The profiled structure is arranged at the midpoint of the long edges at the connection between the two long edges and the connecting side wall 211. In the process of rotation or swinging of the spraying arm, the movement track of the end of the spraying arm is circular or arc-shaped. Therefore, the profiled structure is arranged at the midpoint of the long edges of the rectangular bottom wall 210, and does not need to be arranged circumferentially, thereby avoiding the spraying arm of the sprayer and improving the production efficiency. The profiled structure effectively avoids the situation that the bottom wall 210 and the peripheral wall 220 hinder the movement of the spraying arm, and provides a larger space for the movement of the spraying arm, thereby expanding the spraying range.

[0188] As shown in Figure 24 the embodiment, the profiled structure is a recessed surface recessed outward from the inner container body 200, which has a cavity capable of avoiding the end of the spraying arm of the sprayer. The recessed surface is recessed outward from the inner container in an arc shape or a crescent shape. The shape of the profiled structure matches the rotation track of the end of the spraying arm of the sprayer. In the embodiment, the avoiding structure 2003 is a profiled structure formed by a stamping process, which is simple to form and convenient to manufacture.

[0189] Embodiment Eight

[0190] The inner container structure provided in the embodiment is integrally formed by stamping. In order to facilitate demolding, the draft angle of the inner container bottom is different, and the specific draft angle is as follows.

[0191] As shown in Figure 25 the embodiment, the inner container bottom structure of the inner container body 200 of the dishwasher is provided. The inner container body 200 includes an open top end. The inner container body includes an inner container bottom. The inner container bottom includes a bottom wall 210 and a connecting side wall 211 arranged around the bottom wall. The connecting side wall 211 is transitionally connected with the bottom wall 210. The connecting side wall 211 is inclined outward from the inner container body 200. The connecting side wall 211 and the normal line of the bottom wall 210 of the inner container bottom form a certain transition inclination angle. The transition inclination angle between at least one connecting side wall 211 and the bottom wall 210 is smaller than the transition inclination angle between the other connecting side walls and the bottom wall 210. The inner container bottom is integrally formed by stamping. In order to facilitate demolding, a draft angle is arranged on the inner container bottom. At the same time, the inner container bottom needs to be provided with a filter screen. If the arrangement area of the filter screen is too small, secondary pollution is easily caused. Therefore, the transition inclination angle between one connecting side wall 211 and the bottom wall 210 is smaller than the transition inclination angle between the other connecting side walls and the bottom wall 210, so as to leave enough space for installation of the filter screen.

[0192] Further, the inner container main body is connected with a door body 301, the connecting side wall 211 includes an inner container bottom front wall 2111 near one side of the door body 301, and the transition inclined angle between the inner container bottom front wall 2111 and the bottom wall 210 is smaller than the transition inclined angle between the other connecting side walls and the bottom wall 210. The installation position of the filter screen is arranged between the inner container bottom front wall 2111 near the door body 301 and the bottom wall 210, and the inner container bottom front wall 2111 does not need to avoid the slide rail groove, and can be arranged with the smallest inclined angle to leave a large enough installation space to install a large filter screen.

[0193] The connecting side wall 211 includes an inner container bottom left wall 2111 and an inner container bottom right wall 2113 connected with both ends of the inner container bottom front wall respectively, and an inner container bottom rear wall 2114 opposite to the inner container bottom front wall 2111, and the transition inclined angle between the inner container bottom front wall 2111 and the bottom wall 210 is smaller than the transition inclined angle between the inner container bottom left wall 2112 and the bottom wall 210, the transition inclined angle between the inner container bottom right wall 2113 and the bottom wall 210, and the transition inclined angle between the inner container bottom rear wall 2114 and the bottom wall 210. The inner container main body 200 is designed as a hexahedron structure, which is suitable for most bowl baskets and also facilitates the setting of matched facilities.

[0194] Preferably, the transition angles between the inner container bottom left wall 2111 and the bottom wall 210, the transition inclined angle between the inner container bottom right wall 2113 and the bottom wall 210, and the transition inclined angle between the inner container bottom rear wall 2114 and the bottom wall 210 are the same; which is beneficial to the manufacture of the stamping die.

[0195] Further, the bottom wall 210 near the inner container bottom front wall is provided with an installation position 2102 for installing a filter screen.

[0196] Preferably, a central position of the bottom wall 210 is provided with an installation opening 2103 for installing a sprayer, and the installation position 2102 is arranged between the installation opening 2103 of the sprayer and the inner container bottom front wall 2111; one end of the installation position 2102 is arranged near the installation opening 2103 of the sprayer, and the other end is arranged near the inner container bottom front wall 2111, so as to ensure that the installation position 2102 of the filter screen is as large as possible, so that the filter screen is as large as possible, and secondary pollution caused by too small filter screen is avoided.

[0197] The inner container structure of the dishwasher further includes a bottom support 500 for supporting the inner container main body 200, the bottom support 500 is provided with a slide rail groove 600 for installing a slide rail, and the transition inclined angle between the connecting side wall 211 and the bottom wall 210 corresponding to the slide rail groove 600 on the inner container bottom is greater than the transition inclined angle between the other connecting side walls 211 and the bottom wall 210; so that the bottom wall 210 and the connecting side wall 211 avoid the slide rail groove 600.

[0198] Furthermore, the slide rail grooves 600 are respectively provided on both sides of the base support 500 corresponding to the left wall 2112 and the right wall 2113 of the inner tub bottom. Furthermore, a dishwasher water passage is provided on the outside of the rear wall 2114 of the inner tub bottom, and the transition angle between the rear wall 2114 of the inner tub bottom and the bottom wall 210 avoids the dishwasher water passage.

[0199] Furthermore, the inner liner body 200 also includes a side wall surrounding the bottom of the inner liner, and a connecting part connected to the connecting side wall 211 is provided at the lower edge of the side wall; the connecting part includes a connecting surface connected to the corresponding side wall, the connecting surface is parallel to one side of the corresponding connecting side wall 211, the connecting surface is fitted to one side of the edge of the connecting side wall 211, the connecting surface is welded to the side of the bottom of the inner liner, and the connecting surface is parallel to one side of the corresponding connecting side wall of the bottom of the inner liner for easy welding.

[0200] The connecting part also includes a limiting surface. The lower edge of the side wall is first bent away from / closer to the inner liner body to form a limiting surface. The free end of the limiting surface is then bent and extended towards the bottom of the inner liner to form a connecting surface parallel to the corresponding connecting side wall 211. One end of the connecting side wall 211 abuts against the limiting surface, and one side of the connecting side wall 211 is in contact with the connecting surface. The setting of the limiting surface increases the assembly and welding efficiency of the bottom of the inner liner and the peripheral wall 220 of the inner liner.

[0201] The following example, Example 9, describes the relevant structural features of the inner liner body 200 and the door body 301.

[0202] Example 9

[0203] In this embodiment, as Figure 26 As shown, the dishwasher includes an inner liner body 200 and a door 301 disposed on the side of the inner liner body 200. The inner liner body 200 is provided with a connecting structure 100, and the door 301 is provided with an assembly structure. The inner liner body 200 and the door 301 are integrally connected through the connecting structure 100 and the assembly structure. The assembly structure avoids the sharp edges of the connecting structure wall from scratching the door, and at the same time limits the connecting structure, making the overall assembly effect more compact and firm, thus improving the aesthetics and safety of the dishwasher.

[0204] like Figure 27As shown, the door body 301 includes an outer wall surface away from the inner container main body 200, and the four sides of the outer wall surface are folded inward to form a plane as the thickness of the door body 301, making the door body 301 more aesthetically pleasing. The end of the plane is folded again to form an inner wall surface toward the center of the door body, which is integrally assembled with the inner container 200. When the door body 301 is pulled, the inner container 200 moves with the door body 301. The assembly structure is a protruding rib provided on the inner wall surface. When the inner container 200 and the door body 301 are connected, the connecting structure is located on the inner edge of the protruding rib, which can not only limit the connecting structure, but also prevent the connecting structure from scratching the wall surface of the door body 301, and can also shield the connecting structure, making it more aesthetically pleasing from the outside. The door body 301 is a plate bent into a piece, which is simple in manufacturing process, simple in structure, beautiful in style, and improves the production efficiency.

[0205] The inner wall surface is parallel to the outer wall surface, and the inner wall surface includes four plate pieces connected with the four edges of the outer wall surface. The two adjacent plate pieces are integrally connected. The protruding rib is located on the inner wall surface connected with the upper edge of the door body outer wall surface and the side edges on both sides of the upper edge. The protruding rib on the inner wall surface connected with the upper edge of the door body outer wall surface is a straight long strip arranged in the width direction of the door body 301. The connecting structure extends from the bottom of the protruding rib into the interlayer space between the inner and outer walls of the door body 301 and is clamped by the protruding rib. The protruding rib on the inner wall surface connected with the side edge of the outer wall surface is in the shape of n as a whole, which is consistent with the modeling of the outer edge of the connecting structure, facilitating the limiting and clamping of the outer edge of the connecting structure. The middle part of the protruding rib is a straight long strip arranged in the height direction of the door body 301. The two ends of the straight long strip protruding rib are bent inward in the door body 301. The upper end is bent to be flush with the straight long strip protruding rib extending in the width direction of the door body 301, so that the protruding ribs on the whole door body are connected as a whole, enhancing the strength of the door body 301 and improving the stability and aesthetics of the door body.

[0206] As Figure 28As shown, the ribs on the inner wall surface include rolled ribs 3011 on the inner wall surface connected to the top edge of the outer wall surface of the door body and profiled ribs 3012 on the inner wall surface connected to the side edges of the door body. The rolled ribs 3011 are straight and long in the width direction of the door body 301, and the connecting structure extends from the bottom of the rolled ribs 3011 into the space between the inner and outer wall surfaces of the door body 301 for clamping. The profiled ribs 3012 are n-shaped, which is consistent with the shape of the outer edge of the connecting structure, facilitating the clamping of the outer edge of the connecting structure. The middle part of the profiled ribs 3012 is straight and long in the height direction of the door body 301, and the two ends of the straight and long ribs are bent inwardly into the door body 301. The upper end is flush with the rolled ribs 3011 extending in the width direction of the door body 301, so that the ribs on the entire door body are connected as a whole, enhancing the strength of the door body 301 and improving the stability and aesthetics of the door body.

[0207] In combination Figure 30 and Figure 29 As shown, the rolled ribs 3011 are formed by folding the end of the plate inwardly toward the inner container body 200 and then rolling the end of the plate outwardly toward the outer wall surface of the door body. The end of the rolled structure is flush with the wall surface before folding. The straight connecting structure 1001 on the top surface of the straight side plate of the inner container body 200 has a door body connecting plate 10011 for clamping the rolled ribs. During assembly, the door body connecting plate 10011 is clamped into the bottom of the rolled ribs 3011. The wall surface of the door body connecting plate 10011 close to the inner container body 200 is in contact with the wall surface of the rolled ribs 3011 away from the inner container body 200. The bottom surface of the lower end of the rolled structure of the rolled ribs 3011 is in contact with the lower end of the door body connecting structure 10011. The setting of the lower end of the rolled structure of the rolled ribs 3011 avoids direct contact between the plate edge of the inner wall surface of the door body and the door body connecting structure 10011, which can prevent noise during movement in the use process of the dishwasher and prevent scratches caused by friction during the pushing and pulling process of the dishwasher. In addition, a gasket can be provided between the rolled ribs 3011 and the door body connecting structure 1001 to reduce noise caused by friction.

[0208] Since the door body connecting structure 10011 is made of stainless steel material, when the door body connecting structure 10011 extends from the bottom of the rolled rib 3011 into the interlayer space between the inner and outer wall surfaces of the door body 301, it has a certain elastic variable upward, relying on this elastic variable, the door body connecting structure 10011 and the rolled rib 3011 are stably clamped together, when the door body 301 is pulled outward, the rolled structure 3011 gives the door body connecting structure 10011 an outward thrust, the door body connecting structure 10011 drives the inner container main body 200 to move outward, when the door body 301 is pushed inward, the pressing type structure 3012 needs to transmit the thrust to the inner container main body 200.

[0209] As shown in Figure 29 , the pressing type rib 3012 is a pressing type structure protruding towards the inner container main body 200, the pressing type rib 3012 has a first bending part 30121 and a second bending part 30122, the first bending part 30121 is located at the upper part of the inner wall surface, the end surface of the first bending part 30121 is integrally connected with the end surface of the rolled rib 3011, so that the ribs on the whole door body are connected as a whole, thereby enhancing the strength of the door body 301 and improving the stability and aesthetics of the door body.

[0210] As shown in Figure 31 and Figure 1 , the top surface of the fillet transition side plate on both sides of the flat side plate of the inner container main body 200 is connected with a fillet connecting structure 1002, the fillet connecting structure 1002 has a connecting plate 10021, the upper right angle edge of the door body connecting plate 10021 is engaged with the inner edge of the first bending part 30121, the side surface of the door body connecting plate 10021 away from the inner container main body 200 is attached to the side surface of the door body inner wall surface close to the inner container main body 200, the door body connecting structure 10021 is provided with a through hole, and the door body inner wall surface is also provided with a through hole, the two through holes are coaxially arranged and correspond to each other, the door body connecting structure 10021 and the door body 301 are connected together through a fastening device, the setting of the pressing type rib 3012 can avoid the direct contact of the sharp edge of the connecting structure with the door body inner wall surface, and limit the connecting structure at the same time, which is convenient for assembly and installation, in addition, the pressing type rib 3012 can block the edges of the connecting structure exposed in the line of sight, thereby enhancing the aesthetics of the dishwasher. Figure 25 , Figure 29 and Figure 32The invention also includes an outer plate 302 located on the side of the inner liner body 200. A connecting plate 3021 is provided on the outer plate 302. The connecting plate 3021 is elongated. The upper edge of the outer edge of the connecting plate 3021 is fitted with the lower edge of the door connecting structure 10011. The lower edge of the connecting plate 3021 is fitted with the second bent portion 30122 of the pressed rib 3012. The side edge of the connecting plate 3021 engages with the elongated edge of the middle portion of the pressed rib 3012. A through hole is provided on the connecting plate 3021. A through hole is also provided on the inner wall of the door body located inside the profiled rib 3012. The two through holes are coaxially aligned and correspond one-to-one. A fastening device connects the connecting plate 3021 to the door body 301. The profiled rib 3012 prevents the sharp edges of the connecting plate 3021 from directly contacting the inner wall of the door body, while also limiting the position of the connecting plate 3021 for easy assembly and installation. Furthermore, the profiled rib 3012 prevents the edges of the connecting plate 3021 from being exposed, enhancing the dishwasher's aesthetics. Figure 27 As shown, in this embodiment, when the outer wall of the door 301 is bent to form the thickness of the door, adjacent bending plates form gaps at the four corners of the door (e.g., Figure 33 As shown, in order to improve the stability and aesthetics of the door, a corner bracket 3013 is provided in the gap. The corner bracket 3013 includes a corner bracket base 30131 and a corner bracket plug 30132. During assembly, the corner bracket base 30131 is placed in the interlayer between the inner and outer walls of the door body 301. The part of the corner bracket base 30131 that mates with the corner bracket plug 30132 is placed in the gap. Then, the corner bracket plug 30132 is inserted into the corner bracket base 30131. After the corner bracket 3013 is installed, the subsequent installation between the door body 301 and the connecting structure is carried out.

[0211] The following describes the relevant structural features of the inner liner body 200 and the connecting structure 100 through Examples 10 to 12.

[0231] The related structural features of the cooperation between the inner container body 200 and the bottom support 500 will be introduced below through embodiment thirteen and embodiment fourteen

[0232] Embodiment thirteen

[0233] In the stretching process of the dishwasher, the inner container body 200 is easy to separate from the bottom support 500, therefore, the support structure 506 matched with the inner container body 200 is arranged on the bottom support 500 in this embodiment, so as to increase the stability between the inner container body 200 and the bottom support 500.

[0234] As Figure 41 and Figure 43As shown, the inner container structure provided by the embodiment includes: an inner container body 200, which comprises a bottom wall 210 and a peripheral wall 220; a bottom support 500, which is located below the inner container body 200 and used to support the bottom of the inner container body 200; the dishwasher is stretched through a slide rail, the outer wall of the bottom support 500 is provided with a avoiding structure which avoids the slide rail and cooperates with the slide rail, and the inner wall of the bottom support 500 is provided with a supporting structure 506 corresponding to the avoiding structure and used to support the inner container body 200.

[0235] As shown in Figure 44 and Figure 42 , the avoiding structure is arranged on the two outer sides of the bottom support 500 which are parallel to the stretching direction of the dishwasher, and specifically, the avoiding structure is a slide rail groove 600 arranged on the two outer sides of the bottom support 500, the slide rail groove 600 cooperates with the slide rail on the dishwasher, and the inner wall of the bottom support 500 is provided with a supporting structure 506 corresponding to the position of the slide rail groove 600 and cooperating with the inner container body 200.

[0236] Specifically, the bottom support 500 comprises a bottom support bottom plate 502 and a bottom support side wall 503, the bottom support side wall 503 is arranged circumferentially around the bottom support bottom plate 502 to form a receiving space which can accommodate the bottom of the inner container body 200, the outer part of the two bottom support side walls 503 which are parallel to the stretching direction of the dishwasher is fixedly provided with an upwardly recessed slide rail groove 600, the inner wall of the bottom support side wall 503 is provided with a supporting structure 506 corresponding to the slide rail groove 600 and cooperating with the bottom of the inner container body 200, in order to better support the inner container body 200, a plurality of supporting structures 506 are arranged at intervals in the inner wall of the two bottom support side walls 503 which are parallel to the stretching direction of the dishwasher, the supporting structures 506 not only play a supporting role on the inner container body 200, but also play a role in transmitting force between the bottom support 500 and the inner container body 200 when the dishwasher is stretched, thereby increasing the stability between the inner container body 200 and the bottom support 500.

[0237] In the embodiment, the supporting structure 506 is a supporting table arranged at the bottom of the bottom support side wall 503, in order to improve the supporting stability of the supporting table on the inner container body 200, the number of the supporting tables is large, the supporting tables are arranged circumferentially and uniformly in the inner wall of the bottom support side wall 503, the supporting table comprises a planar part 5061 which is arranged integrally with the bottom support side wall 503, the bottom wall 210 of the inner container body 200 is located on the planar part 5061 of the supporting table, and the top of the supporting table is in surface contact with the bottom of the inner container body 200. By arranging the top of the supporting table as a surface, the contact area between the supporting table and the bottom of the inner container body 200 is increased, thereby improving the effectiveness and stability of a single supporting table.

[0238] As shown in Figure 44As shown, the flat part 5061 includes a flat section 50611 and a U-shaped curved section 50612 connected at both ends of the flat section 50611 to enclose a plane, and the flat section 50611 is fixedly connected to the inner wall of the side wall 503 of the bottom support.

[0239] Specifically, as shown in the drawings, Figure 46 As shown, the side wall 503 of the bottom support in the embodiment includes a vertical plate 5031 and an inclined plate 5032 extending from the upper end of the vertical plate 5031 to the outside of the inner container, and the inclined plate 5032 is arranged circumferentially around the upper edge of the vertical plate 5031 to form an accommodation space with an outwardly diverging upper opening, and the bottom of the inner container body 200 is located in the accommodation space of the bottom support 500. In the embodiment, the flat section 50611 of the flat part 5061 of the support structure 506 is horizontally fixedly arranged on the inner wall of the inclined plate 5032, and the support platform further includes a reinforcing rib 5062 arranged integrally with the flat part 5061, and the reinforcing rib 5062 is a support surface vertically downwardly extending along the outer edge of the U-shaped curved section 50612 of the flat part 5061 and fixedly connected to the inner wall of the inclined plate 5032. The reinforcing rib 5062 is arranged to enhance the stability of the support platform and prevent the support platform from being bent or deformed when the inner container body 200 is supported by the bottom support 500.

[0240] As shown in the drawings, Figure 41 To further improve the stability of the support structure 506 and the bottom of the inner container body 200, a positioning structure 700 is arranged at the junction of the bottom wall 210 and the peripheral wall 220 of the inner container body 200 to cooperate with the support structure 506 and increase the stability between the inner container body 200 and the bottom support 500. Through the arrangement of the positioning structure 700, the top of the support structure 506 can stably abut against the bottom of the inner container body 200, and even when the inner container body 200 vibrates, the support structure 506 will not be separated from the bottom of the inner container body 200, thereby greatly increasing the support stability of the support structure 506.

[0241] Specifically, the positioning structure 700 is a profiled structure arranged at the junction of the bottom wall 210 and the peripheral wall 220 of the inner container body 200 and recessed into the inner container body 200, and the shape and size of the profiled structure match those of the support structure 506. The support structure 506 is clamped in the recessed surface of the lower surface of the profiled structure, and the convex surface of the upper surface of the profiled structure is used to support the shelves in the inner container body 200. The positioning structure 700 in the embodiment is a profiled structure directly formed by a stamping process, which is simple in process and easy to manufacture. The profiled structure not only cooperates with the support structure 506 to prevent the bottom support 500 from being separated from the inner container body 200, but also supports the shelves and the bowl basket in the dishwasher, achieving one object with multiple uses.

[0242] In order to reduce the transmission of the vibration of the inner container body 200 during the pulling process and the spread of the noise, a damping structure is arranged on the support table, which is a rubber damping pad attached to the outer surface of the support table. When the vibration of the inner container body 200 is transmitted to the support table, the vibration is buffered and absorbed by the rubber damping pad due to the elasticity of the rubber damping pad, thereby effectively blocking the transmission of the vibration and reducing the generation of noise, which is beneficial to reduce the noise of the dishwasher.

[0243] Further, in combination with Figure 41 A waterproof structure 501 for preventing water leakage of the inner container is arranged on the bottom support 500 at the position connected with the inner container body 200. Specifically, a connecting structure for connecting the inner container body 200 is arranged on the side wall 503 of the bottom support, and the waterproof structure 501 is arranged around the connecting structure to form a ring-shaped waterproof structure for the bottom of the inner container body 200.

[0244] In combination with Figure 43 , Figure 44 and Figure 44 The connecting structure is arranged at the top of the side wall 503 of the bottom support, and the waterproof structure 501 is a water-blocking rib arranged on the side wall 503 of the bottom support and surrounding the connecting structure. The water-blocking rib is arranged at the outer edge of the top of the side wall 503 of the bottom support and extends circumferentially around the top of the side wall 503 of the bottom support. The connecting structure is arranged at the inner edge of the top of the side wall 503 of the bottom support and is arranged circumferentially and spaced apart. There is a gap between the waterproof structure 501 and the connecting structure, which is convenient for the water flow to flow back to the containing cavity of the bottom support through the gap between them.

[0245] Specifically, the connecting structure is a guide rib 504 arranged on the top of the side wall of the bottom support. The side surface of the guide rib 504 close to the center of the bottom support is attached to the outer wall of the inner container body 200. The guide rib 504 is a plurality of guide ribs arranged circumferentially and spaced apart around the top of the side wall. When the inner container body 200 is placed, the guide rib 504 provides installation guidance for the inner container body 200, which is beneficial to improve the assembly efficiency of the dishwasher. The spaced-apart guide ribs are convenient for the collected water flow to flow back to the containing cavity of the bottom support 500 through the gap between the guide ribs 504. The top of the side wall 503 of the bottom support 500 extends outward to form a ring-shaped plane around the inside of the bottom support 500. The water-blocking rib is arranged at the outer edge of the ring-shaped plane, and the guide rib 504 is arranged at the inner edge of the ring-shaped plane. The ring-shaped plane is formed by bending and extending the top surface of the side wall 503 of the bottom support 500 outward, and the water-blocking rib is arranged at the outer edge of the ring-shaped plane.

[0246] As Figure 45 and Figure 45As shown, the water-blocking ribs extend towards the bottom of the base to form a baffle structure 505. Preferably, the baffle structure 505 is arranged on both sides of the base parallel to the stretching direction of the dishwasher, and is set opposite to each other. In this embodiment, the inner tank body 200 is located in the accommodating space enclosed by the base 500 and the outer panel 302. In this embodiment, since the bottom support sidewall 503 includes a vertical plate 5031 and an inclined plate 5032 extending from the upper end of the vertical plate 5031 to the outside of the inner tub, there is a certain gap between the bottom support sidewall 503 and the baffle structure 505. In this embodiment, the slide rail groove 600 that cooperates with the slide rail is set in the gap between the bottom support sidewall 503 and the baffle structure 505. The slide rail groove 600 is an upwardly recessed groove connecting the vertical plate 5031 and the baffle structure 505 of the bottom support sidewall 503. The slide rail is engaged in the groove. The baffle structure 505 can prevent the bottom support 500 and the slide rail from being directly exposed to the view, improving the aesthetics of the dishwasher, and at the same time, it can fix the outer plate 302 outside the inner tub body 200.

[0247] In this embodiment, the dishwasher structure also includes outer plates 302 arranged on opposite sides of the base and parallel to the stretching direction of the dishwasher, and the baffle structure 505 is connected to the outer plates 302.

[0248] Specifically, such as Figure 47 As shown, the lower edge of the baffle structure 505 is folded outwards towards the base to form a snap-fit ​​plane 5051 perpendicular to the baffle structure. A protruding rib 5052 is provided on the snap-fit ​​plane 5051. The bottom of the outer plate 302 is folded towards the inner liner body 200 to form a folded plane. A slot is provided on the folded plane. The slot and the protruding rib 5052 are in the same position and shape. During assembly, the protruding rib 5052 is snapped into the slot. The baffle structure 505 and the base 500 are integrally formed, saving the manufacturing process of the baffle structure 505 and the connection process between the baffle structure 505 and the base 500, thus improving production efficiency.

[0249] In this embodiment, the distance between the side of the protruding rib 5052 near the baffle structure 505 and the outer surface of the baffle structure 505 is greater than or equal to the wall thickness of the slot. Preferably, the distance between the side of the protruding rib 5052 near the baffle structure 505 and the outer surface of the baffle structure 505 is equal to the wall thickness of the slot. The baffle structure 505 can be used as a positioning structure. When the slot on the folded plane of the outer side plate 302 is inserted and engaged with the protruding rib 5052, the folded plane can first be made to abut against the outer side of the baffle structure 505, and then the slot can be pushed down along the baffle structure 505 to successfully engage with the protruding rib, which improves the assembly efficiency.
