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] As living standards improve, dishwashers are increasingly entering homes. To improve the practicality and convenience of dishwashers, drawer-type dishwashers have emerged. To meet people's demands for the appearance of dishwashers, stainless steel inner tanks are increasingly appearing inside dishwashers. Currently, stainless steel inner tanks are mostly placed directly inside the outer shell used to decorate the inner tank. Due to the certain gap between the shell and the inner tank, the inner tank is prone to shaking inside the shell when the dishwasher is stretched, resulting in poor stability.

[0003] In view of this, the present invention is proposed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a dishwasher inner tub structure in which the support structure set on the base not only supports the inner tub body, but also plays a role in transmitting force between the base and the inner tub body when the dishwasher is stretched.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0006] A dishwasher inner tub structure includes: an inner tub body, the inner tub body including a bottom wall and a peripheral wall; a base support, the base support being located below the inner tub body for supporting the bottom of the inner tub body; the dishwasher is stretched by a slide rail, the base support having an avoidance structure on its exterior to avoid the slide rail, and a support structure for supporting the inner tub body being provided inside the base corresponding to the avoidance structure.

[0007] Furthermore, the avoidance structure includes slide rail grooves provided on both outer sides of the base, the slide rail grooves and slide rails cooperating, and a support structure corresponding to the slide rail grooves in the base is provided to cooperate with the inner liner body.

[0008] Furthermore, the base includes a base plate and side walls. The side walls are arranged circumferentially around the base plate to form a receiving space that can accommodate the bottom of the inner drum body. The outer sides of the two side walls parallel to the stretching direction of the dishwasher are provided with upwardly recessed slide rail grooves. The inner side walls are provided with a corresponding support structure that cooperates with the bottom of the inner drum body.

[0009] Furthermore, the support structure is a support platform provided at the bottom of the side wall, the support platform being evenly distributed circumferentially on the inner wall surface of the side wall, the support platform including a planar portion integrally formed with the side wall, and the bottom wall of the inner liner body located on the planar portion of the support platform.

[0010] Furthermore, the planar portion includes a plane formed by a straight section and U-shaped curved sections connected to both ends of the straight section, and the straight section is fixedly connected to the inner wall surface of the side wall.

[0011] Furthermore, the sidewall includes a vertical plate and an inclined plate that smoothly transitions from the upper end of the vertical plate to the outside of the inner liner. The flat portion is fixedly mounted on the inclined plate. The support platform also includes a reinforcing rib integrally mounted with the flat portion. The reinforcing rib is a support surface that extends vertically downward along the outer edge of the U-shaped curved section of the flat portion and is fixedly connected to the inner wall of the inclined plate.

[0012] Furthermore, the bottom of the inner liner body is provided with a positioning structure that cooperates with the support structure to increase the stability between the inner liner body and the base.

[0013] Furthermore, the positioning structure is provided at the junction of the bottom wall and the peripheral wall of the inner liner body, with a molding structure that is recessed into the inner liner body, and the molding structure matches the shape and size of the supporting structure.

[0014] Furthermore, the support structure engages within the recessed surface of the lower surface of the molded structure, and the protruding surface of the upper surface of the molded structure is used to support the shelves inside the inner liner body.

[0015] Furthermore, it also includes an outer plate located on the outer side of the inner liner body. The upper end of the outer plate is fixedly connected to the inner liner body, and the lower end of the outer plate is fixedly connected to the base support. The inner liner body is located within the accommodating space formed by the base support and the outer plate.

[0016] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0017] 1. The dishwasher inner tub structure provided by the present invention not only supports the inner tub body through the support structure set on the bottom support, but also plays a role in transmitting force between the bottom support and the inner tub body when the dishwasher is stretched.

[0018] 2. The dishwasher inner liner structure provided by the present invention has a pressed structure recessed into the inner liner at the junction of the bottom wall and the peripheral wall of the inner liner body. The support structure is engaged in the recessed surface of the lower surface of the pressed structure, which further increases the stability between the inner liner body and the base.

[0073] like Figure 1 As shown, the dishwasher of this invention includes a connecting structure 100, an inner tub body 200, a door 301, an outer panel 302, a bottom cover 400, and a bottom support 500. The inner tub body 200 is an upward-opening dishwasher inner tub structure. 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 tub. The bottom support 500 provides support and fixation for the inner tub structure. The lower part of the bottom support 500 is provided with a guide rail to facilitate the stretching of the dishwasher. The dishwasher generates noise during use. To reduce the noise during the use of the dishwasher and to improve the overall aesthetics of the dishwasher, in... Outer panels 302 are provided on both sides of the inner tub 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 tub body 200 of the dishwasher through a connecting structure 100, and the lower part of the outer panel 302 is connected to the base support 500. In order to facilitate the stretching of the dishwasher, a door 301 is provided on the dishwasher. The inner tub body 200 and the door 301 are connected through a connecting structure 100, and the lower part of the door 301 is connected to the base support 500. In order to improve the overall stability and safety of the dishwasher, the outer panel 302 is connected to the inner tub body 200, and at the same time, it is also connected to the door 301 and the base support 500.

[0074] The structural features of the inner liner body 200 are described below through Examples 1 to 4.

[0075] Example 1

[0076] The inner liner body 200 provided in this embodiment consists of two spliced ​​parts, with a simple structure and concise manufacturing process, greatly reducing welding processes in the dishwasher manufacturing process and improving assembly efficiency. Figure 1 and Figure 2 As shown, the inner liner body 200 in this embodiment includes an inner liner bottom wall 210 and an inner liner peripheral wall 220. The inner liner bottom wall 210 and the inner liner peripheral wall 220 form an inner liner body 200 with an upward opening. The inner liner peripheral wall 220 is a piece of plate that is bent and rolled into a ring. One end of the plate has a splicing part 221, and the other end overlaps on the splicing part 221. The splicing positions 222 at both ends are located on a plane, which eliminates the influence of dimensional errors on the assembly structure, facilitates the welding of splicing parts with determined final dimensions, results in neat welds, and simplifies the welding plane processing process, thereby improving the manufacturing efficiency of the dishwasher.

[0077] like Figure 3 As shown, the splicing part 221 is a bent structure formed by bending one end of the plate. The end of the bent structure is parallel to the other end 2211 of the plate. The bent structure includes a first bent structure 2212 and a first extension structure 2213. The first bent structure 2212 is formed by bending one end of the plate towards the outside of the inner liner. The first extension structure 2213 is formed by bending and extending the end of the first bent structure 2212 and is parallel to the other end 2211 of the plate.

[0078] like Figure 3 As shown, the side surface of the first extension structure 2213 near the center of the inner liner is attached to the side surface of the other end 2211 of the plate away from the center of the inner liner, and they are integrally connected.

[0079] The inner wall surface of one end of the plate before bending is flush with the inner wall surface of the other end 2211 of the plate.

[0080] The vertical distance of the first bending structure 2212 bending outward from the inner liner is equal to the thickness of the plate. The inner wall surface of one end of the plate before bending is flush with the inner wall surface of the other end 2211 of the plate.

[0081] The end face of the other end 2211 of the plate is in contact with the bending surface of the first bending structure 2212.

[0082] The end face of the other end 2211 of the plate has a gap with the bending surface of the first bending structure 2212.

[0083] The gap between the end face of the other end 2211 of the plate and the bending surface of the first bending structure 2212 is filled with welding material, sealing strip, or baffle.

[0084] like Figure 2 As shown, the inner liner peripheral wall 220 includes four straight side plates, with rounded corner transition side plates between them. The splicing position is located on the straight side plates. The straight side plates include a front plate 201, a rear plate 202, and two side plates 203 located on both sides of the front plate. Preferably, the splicing position is located on the front plate 201.

[0085] like Figure 2 As shown, the outer edge of the bottom wall 210 of the inner liner is folded upward to form a connecting side wall 211, and the bottom of the inner liner forms a structure with a small accommodating cavity that opens upward. The bottom surface of the peripheral wall 220 of the inner liner is spliced ​​with the top surface of the connecting side wall 211.

[0086] like Figure 4 and Figure 5 As shown, the dishwasher is stretched by a slide rail. The connecting side wall 211, which is connected to the bottom plate 204 of the inner tub and is parallel to the stretching direction of the dishwasher, is provided with a receiving part that is recessed towards the center of the inner tub. The receiving part is a recessed surface 2033 that is recessed into the inner tub body 200. The inner tub is provided with a recessed surface 2033 to avoid the slide rail, which is conducive to the expansion of the inner tub. Moreover, the recessed surface 2033 on the connecting side wall 211 results in small stretching and does not affect the structural strength of the inner tub.

[0087] The concave surface 2033 includes a horizontally bent surface 20331 formed by bending the connecting side wall 211 from top to bottom into the inner liner, and a vertically bent surface 20332 formed by bending the end of the horizontally bent surface 20331 downwards. The horizontally bent surface 20331 and the vertically bent surface 20332 are connected and transitioned by a smooth arc surface.

[0088] Preferably, the bottom of the vertical bending surface 20332 bends and extends towards the base plate 204, connecting with the corresponding side of the base plate 204.

[0089] In this invention, the dishwasher inner liner is divided into multiple splicing parts, which are spliced ​​together to form the dishwasher inner liner, instead of using the existing stamping to form the inner liner structure. This avoids the problem that the sheet material is not strong enough after being stretched to a high degree, or even becomes waste material.

[0090] Preferably, the overlapping structure includes a first connecting surface 250 on one of two adjacent splicing components and a second connecting surface 251 on the other splicing component, wherein the first connecting surface 250 and the second connecting surface 251 are fitted together.

[0091] In the above scheme, the overlapping structure is a face-to-face overlapping connection, which is conducive to the splicing and positioning of each splicing component.

[0092] Preferably, in two adjacent splicing components, one splicing component has a first connecting surface 250 that bends and extends outward from the inner liner on one side edge where it splices with the other splicing component, and the other splicing component has a second connecting surface 251 that bends and extends outward from the inner liner on the corresponding side edge. The first connecting surface 250 and the second connecting surface 251 are fitted together.

[0093] In the above scheme, the first connecting surface 250 and the second connecting surface 251 are bonded together and then welded. The first connecting surface 250 can be obtained by bending the edge of the corresponding splicing component at a certain angle, and the second connecting surface 251 can be obtained by bending the edge of another splicing component at a certain angle. The bending angle ensures that the first connecting surface 250 and the second connecting surface 251 are parallel, so that the surfaces can be bonded together.

[0094] See Figure 6 As shown, both the first connecting surface 250 and the second connecting surface 251 are formed by vertically bending the edges of the corresponding splicing components.

[0095] Preferably, the first connecting surface 250 and the second connecting surface 251 are bonded together and then welded together.

[0096] Preferably, the first connecting surface 250 and the second connecting surface 251 are of equal length, and both are very small so as not to affect the installation space of the dishwasher inner tub. Furthermore, the first connecting surface 250 and the second connecting surface 251 are of equal length, and the end face formed after welding is wide, which is not likely to cause cuts to the external structure.

[0097] See Figure 7 As shown, in another embodiment, among two adjacent splicing components, one splicing component has a first connecting surface 250 extending outward from the inner liner along one edge where it joins with the other splicing component. The corresponding edge of the other splicing component has a second connecting surface 251 extending outward from the inner liner. The length of the second connecting surface 251 is greater than the length of the first connecting surface 250. After the first connecting surface 250 and the second connecting surface 251 are fitted together, the portion of the second connecting surface 251 longer than the first connecting surface 250 bends towards the other side of the first connecting surface 250, forming a three-layer bonding surface. This three-layer bonding surface bends and fits against the outer surface of any splicing component. In this embodiment, a three-layer bonding surface is formed, the overlapping structure is relatively stable, and there are no protruding end faces, preventing damage to other components.

[0098] See Figure 8 As shown, in another embodiment, among two adjacent splicing components, one splicing component and the other splicing component have a first connecting surface 250 formed by a recess on one side of the splicing component that extends outward from the inner liner. The corresponding edge of the other splicing component is the second connecting surface 251, and the corresponding edge of the splicing component is attached to the first connecting surface 250.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] Example 2

[0104] 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.

[0105] like Figure 9 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.

[0106] Specifically, the first splicing part 2012 includes a first splicing surface formed by the vertical connection of a first side and a first bottom edge, and the second splicing part 2013 includes a second splicing surface formed by the vertical connection of a second side and a second bottom edge. The first side and / or the second side are provided with a notch. The first side of the first splicing surface and the second side of the second splicing surface are aligned so that the first splicing surface and the second splicing surface are located on the same horizontal plane. When splicing, the notch forms an installation port 2011 that can be used to place a detergent adding device. The size of the notch can be set to different sizes and shapes according to the size of the detergent adding device.

[0107] For example, a notch can be opened on the first side of the first splicing surface, and a notch can be opened at the corresponding position on the second side. When the first splicing surface and the second splicing surface are spliced, the middle notch of the first side and the middle notch of the second side form an installation port 2011 that can be used to place a detergent adding device.

[0108] As an alternative to the above solution, a notch can also be provided on one side edge of the first or second splicing surface. For example, a notch can be provided on one side edge of the first splicing surface. When the first and second splicing surfaces are spliced, the notch portion of the first splicing surface and the splicing position 222 of the second splicing surface form an installation opening 2011 for placing a detergent dispensing device. Alternatively, a notch can be provided on one side edge of the second splicing surface.

[0109] In this embodiment, an installation port 2011 for placing a detergent additive device is formed at the splicing position 222, which reduces the length of the weld and can even eliminate the intermediate weld, thus reducing welding steps and saving costs.

[0110] Furthermore, a fixing plate is provided at the installation port 2011. The fixing plate is located on the outside of the inner tank body 200. The detergent adding device is fixedly connected to the fixing plate by screws, and thus fixed to the inner tank.

[0111] Preferably, a rubber ring or other sealing structure matching the shape and size of the mounting port 2011 is provided between the fixing plate and the detergent adding device to increase the sealing between the detergent adding device and the inner tank body 200.

[0112] Example 3

[0113] In this embodiment, the dishwasher inner drum body 200 is composed of three spliced ​​parts, and the specific formation method is as follows.

[0114] like Figure 10As shown, in this embodiment, the dishwasher inner tub body 200 is composed of three splicing components, including a first splicing component, a second splicing component, and a third splicing component. The second splicing component and the third splicing component are located on both sides of the first splicing component and are parallel to the stretching direction of the dishwasher. The splicing position of the second splicing component / third splicing component and the first splicing component is located on a plane.

[0115] The first splicing component includes a bottom plate 204 of the inner liner body and a front plate 201 and a rear plate 202 connected to the bottom plate 204 and perpendicular to the stretching direction of the dishwasher.

[0116] The second / third splicing component includes a side plate 203 parallel to the stretching direction of the dishwasher. The second / third splicing component also includes an extension connected to the side plate 203 and bent toward the opposite side plate. The extension is connected to the first splicing component and includes a rounded corner structure between the inner wall surfaces. The extension is provided so that the splicing position of the second / third splicing component and the first splicing component is located on a plane.

[0117] The second splicing component / third splicing component is integrally formed by stamping. The extension includes a first extension surface 2031 located on the bottom surface of the side plate 203 and a second extension surface 2032 located on the side surface of the side plate 203. After forming the rounded corner structure between the inner wall surfaces, the extension continues to extend straight towards the opposite side plate. The first extension surface 2031 is connected to the bottom plate 204 in the first splicing component, and the second extension surface 2032 is connected to the front plate 201 / rear plate 202 in the first splicing component.

[0118] like Figure 11 The figure shown is a cross-sectional view of the inner liner body 200 of the present invention. The dishwasher is stretched by a slide rail. The side plate 203 of the second splicing component / third splicing component includes a recessed surface 2033 at point A in embodiment five. The recessed surface 2033 is a receiving part recessed towards the center of the inner liner. The receiving part can be fitted with a slide rail to facilitate stretching the dishwasher and taking out and putting in the tableware in the dishwasher.

[0119] like Figure 5 As shown, the concave surface 2033 includes a horizontally bent surface 20331 formed by bending from top to bottom into the inner liner, and a vertically bent surface 20332 formed by bending the end of the horizontally bent surface 20331 downwards. The horizontally bent surface 20331 and the vertically bent surface 20332 are connected and transitioned by a smooth arc surface.

[0120] Preferably, in this embodiment, the bottom of the vertical bending surface 20332 is provided with a first extension surface 2031 that bends and extends toward the base plate 204, and the first extension surface 2031 is connected to the corresponding side of the base plate 204.

[0121] In the above scheme, the bottom edge of the horizontal bending surface 20331 is bent towards the bottom to form the first extension surface 2031. The first extension surface 2031 is preferably in the same plane as the base plate 204. In this way, the splicing position of the bottom edge of the base plate 204 and the side plate 203 is on the plane, not at the corner, which facilitates the splicing and alignment of each splicing part, and moves the welding position to the plane, reducing the welding difficulty.

[0122] Preferably, the side plate 203 is provided with a second extension surface 2032 on both sides, which bends and extends toward the front plate 201 and the rear plate 202, and the second extension surface 2032 is connected to the corresponding front plate 201 or rear plate 202.

[0123] In the above scheme, the two sides of the side plate 203 are bent to form the second extension surface 2032 to the front plate 201 and the rear plate 202. The side of the second extension surface 2032 that is spliced ​​with the front plate 201 or the rear plate 202 is in the same plane as the front plate 201 or the rear plate 202, thereby avoiding the corner and facilitating welding and fixing.

[0124] In this embodiment, the design of the second extended surface 2032 prevents splicing on the recessed surfaces 2035 / 2033, and shifts the splicing position to the plane, simplifying the welding process.

[0125] In this embodiment, the base plate 204, the front plate 201, and the rear plate 202 form a first splicing component, and the two side plates 203 are the second splicing component and the third splicing component, respectively. The connection method between the splicing components is the same as that in Embodiment 1. The first splicing component is provided with the first connecting surface 250 at the notch on both sides. The two side plates 203 are provided with the second connecting surface 251 on both sides and the bottom edge. The first connecting surface 250 and the second connecting surface 251 are connected.

[0126] Preferably, the bottom of the two side plates 203 is provided with a first extension surface 2031 that bends toward the base plate of the first splicing component, the first extension surface 2031 is provided with a first connecting surface 250 on the edge, and the base plate is provided with a second connecting surface 251 on both sides.

[0127] In the above scheme, the bottom of the side plate 203 is bent horizontally and the edge is provided with a first connecting surface 250, so that the splicing point avoids the corner between the side plate 203 and the bottom plate, so that the splicing position is located on the plane, and the overlapping structure can prevent the two splicing parts from processing errors, can be stably overlapped, and then welded and fixed.

[0128] Preferably, each of the two side plates 203 is provided with a second extension surface 2032 that bends and extends toward the front plate 201 and the rear plate 202, and the edge of the second extension surface 2032 is provided with the first connecting surface 250. The second connecting surface 251 is provided on each side of the front plate 201 and the rear plate 202 respectively.

[0129] Similarly, the design of the second extension surface 2032 avoids the corner between the side plate 203 and the front plate 201 or the rear plate 202 at the splicing point, so that the splicing position is on the plane, and the overlapping structure can prevent the two splicing parts from processing errors, can be stably overlapped, and then welded and fixed.

[0130] Preferably, the first extension surface 2031 and the second extension surface 2032 smoothly transition to form a U-shaped arc surface, and the U-shaped arc surface smoothly joins the notch side of the first splicing component.

[0131] Example 4

[0132] Unlike the above embodiments, in this embodiment, the inner liner body 200 is formed by splicing together a polygonal plate, and the specific formation method is as follows.

[0133] like Figure 12 As shown, in this embodiment, the inner tank body 200 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 bent and spliced ​​to form the side wall of the dishwasher.

[0134] In the above solution, the inner liner is formed by bending a single piece of sheet metal, which reduces the length of the weld seam and simplifies the processing technology.

[0135] Preferably, the base plate 204 has multiple sides, and the side plate assembly includes plates that are respectively connected to each side of the base plate 204, and each plate is bent toward the same side of the base plate 204 to form the side wall of the dishwasher.

[0136] In the above solution, the solution of the present invention can produce inner liner of different shapes, bend each plate relative to the bottom plate 204, and splice adjacent two plates to form a ring-shaped side wall of the dishwasher.

[0137] Preferably, the base plate 204 is a quadrilateral plate, with each of the four sides of the quadrilateral plate connected to a plate body. The four plates body are bent toward the same side of the base plate 204 to form the side wall of the dishwasher. The opposite sides of two adjacent plates body are in contact and connected using a set process.

[0138] Preferably, the opposite sides of two adjacent plates are in contact and welded together.

[0139] Preferably, in two adjacent plates on the inner liner, a connecting part is provided on the side of one plate, and the plate is connected to the other plate through the connecting part;

[0140] Preferably, the connecting part includes a flange provided on one side edge of the plate. After both plates are bent relative to the base plate 204, the side edge of one plate is attached to the flange of the adjacent plate.

[0141] In the above scheme, the design of the flange structure allows two adjacent plates to fit together and be positioned, which is convenient for fixing by welding. The flange also provides left and right support and limit for the other plate, which facilitates the welding process.

[0142] The flange is formed by bending the edge of the panel towards the plane containing the adjacent panel. When the inner liner comprises four panels, the flange is formed by bending the edge of the panel perpendicularly. The bending direction can be towards the panel it is joined to, or away from the panel it is joined to.

[0143] Preferably, the inner liner includes two first plates 8001 disposed on opposite sides of the bottom plate 204, and the other two plates of the inner liner are second plates 8002. The bottom of the first plates 8001 is provided with recessed surfaces 2033 / 2035 extending along the length of the plate and recessed in the direction of bending towards each plate. The flanges are provided on both sides of the first plates 8001. After each plate is bent relative to the bottom plate 204, the edges of the two second plates 8002 are attached to the flanges.

[0144] Preferably, the outlines of the two side edges of the second plate 8002 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 edge is uniform and there are no protruding parts.

[0145] Preferably, the first plate 8001 is stamped to form a recessed surface 2033 / 2035 that gradually narrows towards the base plate 204 and connects to the base plate 204 on one side. The second plate 8002 is stamped to form a recessed surface 2033 / 2035 that gradually narrows towards the bottom edge and connects to the base plate 204 on one side. After each plate is bent, the edges of the recessed surfaces 2033 / 2035 of two adjacent plates contact and connect accordingly. In the above scheme, a recessed surface 2033 / 2035 is also provided on the two second plates 8002 corresponding to the recessed surface 2033 / 2035 on the first body. The recessed surface 2033 / 2035 of the first plate 8001 and the recessed surface 2033 / 2035 of the second plate 8002 are connected, and the planes at the top of the recessed surfaces 2033 / 2035 of the two are also connected accordingly, thereby avoiding the connection between adjacent plates through curved surfaces and planes, and simplifying the splicing process.

[0146] The following provides a method for manufacturing the dishwasher inner tub, including the following steps:

[0147] S1. Stamp an integral bottom plate 204 and side plate assembly onto the sheet metal according to the inner liner dimensions;

[0148] S2. Bend the panels in the side panel assembly to form the side wall of the dishwasher;

[0149] S3. Connect and fix the various plates together using a connection process.

[0150] Preferably, a quadrilateral base plate 204 and four plates respectively connected to the four sides of the base plate 204 are stamped on the sheet material. Each plate is bent vertically toward the same side of the base plate 204, so that the plates are spliced ​​together to form the side wall of the dishwasher, and the two opposite sides of the two adjacent plates are welded.

[0151] Preferably, in step S1, a recessed surface 2033 is punched out at the bottom of the two plates on both sides of the base plate 204 along the bending direction of the plates.

[0152] Alternatively, in step S1, an outwardly convex profile is formed on each of the two plates on both sides of the base plate 204, with the profile being pressed in the opposite direction to the bending direction of the plate. The recessed surface 2035 is formed between the bottom surface of the outwardly convex profile and the bottom edge of the plate.

[0153] The specific structural features of the inner liner body 200 are described below through Examples 5 to 8.

[0154] Example 5

[0155] See Figures 13 to 15 As shown, in this embodiment, the side plate 203 is provided with an outward protrusion structure that protrudes from the inside of the inner liner to the outside. The setting of the outward protrusion structure increases the capacity of the inner liner and realizes the expansion of the inner liner.

[0156] Preferably, the inner liner is slidably disposed within the shell or bracket of the dishwasher, and the side plate includes two side plates extending along the sliding direction of the inner liner. Both side plates are configured as outwardly convex structures protruding away from the opposite side plate, thereby increasing the size of the inner liner and increasing the internal space of the inner liner in a direction perpendicular to the sliding direction of the inner liner.

[0157] In the above scheme, the inner liner body 200 includes a front panel 201, a rear panel 202, side panels 203 oppositely arranged on both sides of the front panel, and rounded transition side panels connecting the front panel 201 / rear panel 202 and the side panels 203 respectively. The convex structure of the side panels is obtained by stamping and pressing a large area in the middle of the side panel 203, forming a structure with a convex center and concave periphery, thereby increasing the internal space of the inner liner. Specifically, the side panels are stamped with an outward convex molding 2034 in the opposite direction to the opposite side panel, forming a shell structure in which the bottom wall convexes and the peripheral wall extends towards the opposite side panel. In this method, the large area of ​​the side panel is stamped, increasing the internal space of the inner liner.

[0158] Preferred, such as Figure 15 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.

[0159] 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.

[0160] 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.

[0161] 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.

[0162] 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 5 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.

[0163] See Figure 16As shown, the upper part of the protruding molded type 2034 is connected to the top edge of the side plate 203 through the third arc surface 800. The third arc surface 800 gradually narrows from bottom to top towards the axis of the inner liner, and the narrowed part is recessed into the inner liner, which has the function of blocking the upward sprayed washing water. One external protruding molded type 2034 realizes multiple structural functions.

[0164] Furthermore, the front panel 201 / rear panel 202 of the inner liner can also be similar to the two side panels 203, configured as a structure that protrudes outward from the inner liner, thereby expanding the inner liner's capacity. Its structure can be similar to the two side panels 203 mentioned above, and will not be described in detail here.

[0165] Example 6

[0166] In this embodiment, the bottom wall 210 of the inner liner body 200 is tapered towards the bottom of the inner liner, which facilitates the collection of water flow inside the inner liner body 200. At the same time, the inner liner itself is reinforced by forming reinforcing ribs through stamping.

[0167] join Figure 1 , Figure 17 , Figure 19 As shown in the figure, this embodiment provides a dishwasher inner tank structure. The inner tank body 200 includes a bottom wall 210 and a peripheral wall 220. The peripheral wall 220 includes a front plate 201, a rear plate 202, and two side plates 203. The lower edge of the peripheral wall 220 is arranged circumferentially around the outer edge of the bottom wall 210 to form a receiving cavity with a top opening. The bottom wall 210 is arranged inclined downward along the lower edge of the peripheral wall 220 to form a converging shape that converges towards the bottom of the inner tank, so as to facilitate the downward collection of water flow in the inner tank body 200.

[0168] Furthermore, such as Figure 18 As shown, a through hole 2041 is provided on the bottom wall 210 of the inner liner. The through hole 2041 is located below the plane where the lower edge of the peripheral wall 220 is located. The through hole 2041 and the plane where the lower edge of the peripheral wall 220 is located form a certain height difference, which facilitates the downward discharge of water. The bottom wall 210 extends downward along the lower edge of the peripheral wall 220 towards the through hole 2041. The bottom wall 210 is in a converging shape from the lower edge of the peripheral wall 220 towards the through hole 2041, which facilitates the water in the inner liner to flow into the through hole 2041 and be discharged.

[0169] In this embodiment, the bottom wall 210 includes four straight surfaces 2042 that are inclinedly arranged between the lower edge of the peripheral wall 220 and the through hole 2041. The straight surfaces 2042 that are inclined downward form four reinforcing ribs between the straight surfaces 2042, which enhances the structure of the inner liner itself.

[0170] The preferred bottom wall 210 includes a straight surface 2042 and a transition surface 2043 that are inclinedly connected between the lower edge of the peripheral wall 220 and the through hole 2041, and the transition surface 2043 and the straight surface 2042 are arranged at intervals to form the inner liner bottom wall 210.

[0171] In this embodiment, the through hole 2041 can be located at any position on the bottom wall 210. However, in order to increase the overall aesthetics of the inner liner body 200 and to allow the accumulated water in the inner liner to drain in a timely manner, it is preferable that the through hole 2041 is opened at the center of the bottom wall 210, the transition surface 2043 can be located at the centerline of the bottom wall 210, the through hole 2041 is the center hole located at the intersection of the centerlines of the bottom wall 210, and the flat surface 2042 is located between two adjacent transition surfaces 2043.

[0172] As a more preferred embodiment of the above solution, the transition surface 2043 is located at the diagonal of the bottom wall 210 of the inner liner, the through hole 2041 is the central hole located at the intersection of the diagonals of the bottom wall 210, and the flat surface 2042 is located between two adjacent transition surfaces 2043. The transition surface 2043 set between two adjacent flat surfaces 2042 can prevent some debris from getting stuck in the gap due to the small included angle between the two adjacent flat surfaces 2042, which would make it difficult to clean and contaminate the internal space of the dishwasher.

[0173] Specifically, such as Figure 18As 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.

[0174] 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.

[0175] 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.

[0176] In another approach, a transition surface 2043 can be formed between two adjacent straight surfaces 2042 by using a chamfering machine to round the corners. By adjusting the chamfering angle of the chamfering machine, the arc length of the rounded corner structure gradually decreases along the direction close to the through hole 2041, so that the transition surface 2043 forms a converging shape that gradually narrows towards the through hole 2041, which facilitates the gradual convergence and discharge of water. The transition surface 2043 formed by chamfering can strengthen the structure of the inner liner itself, and the transition surface 2043 has a groove-shaped receiving space, which facilitates flow guidance.

[0177] The dishwasher inner tank bottom wall 210 provided by the present invention is integrally formed by stamping, which has a simple structure, is easy to manufacture, and improves production efficiency. The radial four-sided prismatic bottom wall 210 formed by stamping not only strengthens the structure of the inner tank itself, but also facilitates the flow of water to the center.

[0178] As a variation of this embodiment, the bottom wall 210 is formed by splicing multiple plates inclined downwards towards the through hole 2041. Multiple rounded corners are formed at the splicing points, and the plates are smoothly connected. The arc length of the rounded corners gradually increases in the direction away from the through hole 2041. Specifically, the bottom wall 210 is formed by splicing four plates symmetrically arranged along the diagonal of the bottom wall 210 towards the through hole 2041. The edges of the plates form radial ribs at the diagonal positions of the bottom wall 210 to facilitate water flow collection.

[0179] Example 7

[0180] When the dishwasher is cleaning, the inner tub body 200 is equipped with a sprayer for cleaning dishes. The sprayer includes a spray arm with multiple spray holes. The spray arm rotates or swings in the horizontal plane under the drive of a motor. During the rotation or swinging process, the bottom wall 210 or the peripheral wall 220 of the inner tub body 200 may obstruct the movement of the spray arm, thus limiting the spray range and causing poor washing effect and incomplete cleaning of the dishwasher.

[0181] To solve the above problems, this embodiment, based on embodiment six, provides an obstacle avoidance structure 2003 in the inner liner body 200 to avoid the spray arm of the dishwasher sprayer.

[0182] Combination Figures 19 to 24As shown, this embodiment provides a dishwasher inner liner structure, including an inner liner body 200, the inner liner body 200 including a bottom wall 210 and a peripheral wall 220; it also includes a sprayer, the sprayer is installed at the bottom of the inner liner body 200, specifically, the sprayer is installed at the through hole 2041 position of the bottom wall 210, and the bottom of the inner liner body 200 is provided with a avoidance structure 2003 for avoiding the sprayer.

[0183] See Figure 24 As shown, in this embodiment, the bottom wall 210 and the peripheral wall 220 are connected by a connecting side wall 211. The connecting side wall 211 has its outer edge folded upward, and the bottom wall 210 forms a structure with an upward-facing opening and a small accommodating cavity. The connecting side wall 211 includes an inner liner bottom front wall 2111 near the door body 301, and inner liner bottom side walls located on both sides of the inner liner bottom front wall 2111. The inner liner bottom side walls include an inner liner bottom left wall 2112 and an inner liner bottom right wall 2113.

[0184] In this embodiment, the avoidance structure 2003 is a molding structure set at the bottom of the inner liner body 200. The molding structure is a recessed surface set at the junction of the bottom wall 210 and the bottom side wall of the inner liner, which is recessed towards the outside of the inner liner body 200. The position and height of the molding structure can be determined according to the height of the spray arm, and can be set at the junction of the bottom wall 210 and the bottom side wall of the inner liner, or on the bottom side wall or the peripheral wall 220 of the inner liner.

[0185] The recessed surface formed by stamping, which curves outward from the inner tank body 200, not only serves to avoid the spray arms of the sprayer but also expands the capacity. For example... Figure 19 and Figure 21 As shown, the molding structure is located at the midline endpoints on both sides of the bottom wall 210. The molding structure expands outward to avoid the spray arm of the sprayer, thereby expanding the spray range and avoiding the formation of washing dead corners during the spraying process.

[0186] In the above scheme, the bottom wall 210 can be square, and the molding structure is set at the midpoint of the intersection of the four edges of the square bottom wall 210 and the peripheral wall 220. The bottom wall 210 can also be rectangular. This embodiment takes a rectangular bottom wall as an example. Specifically, the outer edge of the bottom wall 210 includes two long sides and two short sides arranged opposite each other. The molding structure is set at the midpoint of the two long sides at the connection position of the two long sides and the connecting side wall 211. During the rotation or swing of the spray arm, the movement trajectory of the end of the spray arm is circular or arc-shaped. Therefore, setting the molding structure at the midpoint of the two long sides of the rectangular bottom wall 210 avoids the need for circumferential setting, thus avoiding the spray arm of the sprayer and improving production efficiency. The molding structure effectively avoids the bottom wall 210 and the peripheral wall 220 from obstructing the movement of the spray arm, providing it with more room to move and expanding the spray range.

[0187] like Figure 23 As shown, in this embodiment, the molding structure is a recessed surface formed by a stamping process that is concave to the outside of the inner liner body 200. The recessed surface has a cavity that can avoid the end of the spray arm of the sprayer. The recessed surface is arc-shaped or crescent-shaped and concave to the outside of the inner liner. The shape of the molding structure matches the rotation trajectory of the end of the spray arm of the sprayer. In this embodiment, the avoidance structure 2003 is a molding structure formed by a stamping process, which is simple to form and easy to manufacture.

[0188] Example 8

[0189] The inner liner structure provided in this embodiment has an inner liner bottom that is integrally stamped. To facilitate demolding, the draft angle of the inner liner bottom is different, as detailed below.

[0190] like Figure 24 As shown, this embodiment provides an inner tank bottom structure for a dishwasher inner tank body 200, including an inner tank body 200 with a top opening. The inner tank body includes an inner tank bottom, which includes a bottom wall 210 and connecting side walls 211 arranged around the bottom wall. The connecting side walls 211 and the bottom wall 210 are transitionally connected. The connecting side walls 211 are all inclined outwards from the inner tank body 200, and a certain transition inclination angle is formed between the connecting side walls 211 and the normal of the bottom wall 210 of the inner tank bottom. At least one of the connecting side walls 211 and the bottom wall 210 has a smaller transition inclination angle than the other connecting side walls and the bottom wall 210. The inner tank bottom is integrally stamped. In order to facilitate demolding, a draft angle is set on the inner tank bottom. At the same time, considering that a filter screen needs to be installed on the inner tank bottom, if the area of ​​the filter screen is too small, it will easily cause secondary pollution. Therefore, a transition inclination angle between a connecting side wall 211 and the bottom wall 210 is set to be smaller than the transition inclination angle between the other connecting side walls and the bottom wall 210, so as to leave enough space for the filter screen installation.

[0191] Furthermore, the inner liner body is connected to a door 301, and the connecting sidewall 211 includes an inner liner bottom front wall 2111 near the door 301. The transition inclination angle between the inner liner bottom front wall 2111 and the bottom wall 210 is smaller than the transition inclination angle between other connecting sidewalls and the bottom wall 210. The filter screen is installed between the inner liner bottom front wall 2111 and the bottom wall 210 near the door 301. The inner liner bottom front wall 2111 does not need to avoid the slide rail groove, and a smaller inclination angle can be set to leave enough installation space to install a filter screen of the largest possible size.

[0192] The connecting sidewall 211 includes a left wall 2111 and a right wall 2113 of the inner liner bottom, respectively connected to both ends of the front wall of the inner liner bottom, and a rear wall 2114 of the inner liner bottom opposite the front wall 2111. The transition angle between the front wall 2111 and the bottom wall 210 is smaller than the transition angle between the left wall 2112 and the bottom wall 210, the transition angle between the right wall 2113 and the bottom wall 210, and the transition angle between the rear wall 2114 and the bottom wall 210. The inner liner body 200 is designed with a hexahedral structure, which is compatible with most bowl baskets and also facilitates the installation of its supporting facilities.

[0193] Preferably, the transition angle between the left wall 2111 and the bottom wall 210 of the inner liner, the transition tilt angle between the right wall 2113 and the bottom wall 210 of the inner liner, and the transition tilt angle between the rear wall 2114 and the bottom wall 210 of the inner liner are all the same; this is beneficial for the manufacture of stamping dies.

[0194] Furthermore, the bottom wall 210 is provided with a mounting position 2102 for installing a filter screen on the side near the front wall of the inner liner.

[0195] Preferably, an installation port 2103 for installing a sprayer is provided at the center of the bottom wall 210, and the installation position 2102 is located between the installation port 2103 of the sprayer and the bottom front wall 2111 of the inner tank. One end of the installation position 2102 is located near the installation port 2103 of the sprayer, and the other end is located near the bottom front wall 2111 of the inner tank, 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 to avoid secondary pollution caused by the filter screen being too small.

[0196] The dishwasher inner tank structure also includes a base support 500 for supporting the inner tank body 200. The base support 500 is provided with a slide rail groove 600 for installing slide rails. The transition inclination angle between the connecting side wall 211 and the bottom wall 210 on the bottom of the inner tank corresponding to the slide rail groove 600 is greater than the transition inclination angle between other connecting sides 211 and the bottom wall 210, so that the bottom wall 210 and the connecting side wall 211 avoid the slide rail groove 600.

[0197] 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.

[0198] 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.

[0199] 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.

[0200] The following example, Example 9, describes the relevant structural features of the inner liner body 200 and the door body 301.

[0201] Example 9

[0202] In this embodiment, as Figure 25 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.

[0203] like Figure 26As shown, the door body 301 includes an outer wall surface away from the inner liner body 200. The four sides of the outer wall surface are folded towards the inner liner body 200 to form a plane, which serves as the thickness of the door body 301, making the door body 301 more aesthetically pleasing. The ends of the plane are folded towards the center of the door body to form an inner wall surface. The inner wall surface is integrally assembled with the inner liner 200. When the door body 301 is pulled, the inner liner 200 moves with the door body 301. The assembly structure is a rib set on the inner wall surface. When connecting the inner liner 200 and the door body 301, the connecting structure is located on the inner edge of the rib. This can limit the connection structure, prevent the connection structure from scratching the wall surface of the door body 301, and also cover the connection structure, making it more aesthetically pleasing from the outside. The door body 301 is formed by bending a single piece of plate, which is simple to manufacture, has a concise structure, a beautiful appearance, and improves manufacturing efficiency.

[0204] The inner wall surface is parallel to the outer wall surface. The inner wall surface includes four plates connected to the four edges of the outer wall surface. Adjacent plates are integrally connected. Raised ribs are located on the inner wall surface connected to the upper edge of the outer wall surface and to the side edges on both sides of the upper edge. The raised ribs on the inner wall surface connected to the upper edge of the outer wall surface are straight, elongated strips extending along the width of the door body 301. The connecting structure extends from the bottom of the raised ribs into the interlayer space between the inner and outer walls of the door body 301, and is engaged through the raised ribs; the side edges of the outer wall surface are connected... The ribs on the inner wall are generally n-shaped, which is consistent with the outer edge of the connecting structure. This facilitates the limiting and locking of the outer edge of the connecting structure. The middle part of the rib is a straight strip that extends along the height of the door body 301. The two ends of the straight strip rib are bent inwards towards the door body 301. After the upper end is bent, it is flush with the straight strip rib that extends along the width of the door body 301, so that the ribs on the entire door body are connected as a whole, which enhances the strength of the door body 301 and improves the stability and aesthetics of the door body.

[0205] like Figure 27As shown, the raised ribs on the inner wall surface include rolled ribs 3011 and pressed ribs 3012. The rolled ribs 3011 are located on the inner wall surface connected to the edge of the outer wall surface of the door, and the pressed ribs 3012 are located on the inner wall surface connected to the side edges of both sides of the door. The rolled ribs 3011 are straight strips extending along the width direction of the door 301. The connecting structure extends from the bottom of the rolled ribs 3011 into the interlayer space between the inner and outer walls of the door 301, and is engaged by the ribs; the pressed ribs 3012... 12 is n-shaped, and this shape is consistent with the outer edge of the connecting structure, which facilitates the limiting and locking of the outer edge of the connecting structure. The middle part of the pressed rib 3012 is a straight strip set along the height direction of the door body 301. The two ends of the straight strip rib are bent inwards towards the door body 301. After the upper end is bent, it is flush with the rolled rib 3011 extending along the width direction of the door body 301, so that the ribs on the entire door body are connected as a whole, which enhances the strength of the door body 301 and improves the stability and aesthetics of the door body.

[0206] Combination Figure 28 and Figure 30 As shown, the rolled rib 3011 is a rolled edge structure formed by folding the end of the plate towards the inner liner body 200 and then rolling it towards the outer wall of the door. The end of the rolled edge structure is flush with the wall surface before folding. The inner liner body 200 has a flat connecting structure 1001 on the top surface of the flat side plate. The flat connecting structure 1001 has a door connecting plate 10011 that engages with the rolled rib. During assembly, the door connecting plate 10011 is inserted from the bottom of the rolled rib 3011. The wall surface of the door connecting plate 10011 near the inner liner body 200 and the wall surface of the rolled rib 3011 are connected. The anti-roll structure is attached to the wall surface away from the inner liner body 200. The bottom surface of the lower end of the roll structure of the roll rib 3011 is attached to the plane connected to the lower end of the door body connecting structure 10011. The setting of the lower end of the roll structure of the roll rib 3011 avoids the edge of the inner wall panel of the door body from directly contacting the door body connecting structure 10011. This prevents noise during the operation of the dishwasher and also avoids scratches caused by friction during the pushing and pulling of the dishwasher. At the same time, a gasket can be placed between the roll rib 3011 and the door body connecting structure 1001 to reduce noise caused by friction.

[0207] Because the door connecting structure 10011 is made of stainless steel, when the door connecting structure 10011 extends from the bottom of the rolled rib 3011 into the interlayer space between the inner and outer walls of the door body 301, it has a certain upward elastic variable. Relying on this elastic variable, the door connecting structure 10011 and the rolled rib 3011 are stably engaged together. When the door body 301 is pulled outward, the rolled structure 3011 provides the door connecting structure 10011 with an outward pushing force, and the door connecting structure 10011 drives the inner liner body 200 to move outward. When the door body 301 is pushed inward, the pushing force needs to be transmitted to the inner liner body 200 through the pressing structure 3012.

[0208] like Figure 29 As shown, the pressed rib 3012 is a pressed structure that protrudes towards the inner liner body 200. The pressed rib 3012 has a first bending part 30121 and a second bending part 30122. The first bending part 30121 is located on the upper part of the inner wall surface. The end face of the first bending part 30121 is integrally connected with the end face of the rolled rib 3011, so that the rib shapes on the entire door body are connected as a whole, which enhances the strength of the door body 301 and improves the stability and aesthetics of the door body.

[0209] Combination Figure 29 and Figure 31 As shown, a rounded corner connecting structure 1002 is connected to the top surface of the rounded corner transition side plates on both sides of the flat side plate of the inner liner body 200. The rounded corner connecting structure 1002 has a connecting plate 10021, and the upper right-angle edge of the door body connecting plate 10021 engages with the inner edge of the first bending part 30121. The side surface of the door body connecting plate 10021 away from the inner liner body 200 is in contact with the side surface of the inner wall of the door that is close to the inner liner body 200. The door body connecting structure 1002... The door body 301 has a through hole on its upper surface and another through hole on its inner wall. These two through holes are coaxially aligned and correspond one-to-one. A fastening device connects the door body connecting structure 10021 to the door body 301. The profiled rib 3012 prevents the sharp edges of the connecting structure from directly contacting the inner wall of the door, while also limiting the position of the connecting structure for easy assembly and installation. Furthermore, the profiled rib 3012 prevents the edges of the connecting structure from being exposed, enhancing the dishwasher's aesthetics. Figure 1 , Figure 25 and Figure 29The 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 32 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 27 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.

[0210] The following describes the relevant structural features of the inner liner body 200 and the connecting structure 100 through Examples 10 to 12.

[0211] Example 10

[0212] This embodiment is a further limitation of the above embodiment nine, such as... Figure 33 As shown, the inner liner body 200 includes side panels with a flat top surface, and the side panels are connected by rounded corner transition side panels. The connection structure 100 includes a flat connection structure 1001 connected to the top of the side panel and a rounded corner connection structure 1002 connected to the rounded corner transition side panel.

[0213] The straight connection structure 1001 is long and narrow. The bottom surface of the straight connection structure 1001 is a straight surface with the same shape as the top surface of the connected side wall. After connecting with the top surface of the side wall, it folds outward towards the inner tank body 200. In this embodiment, the straight connection structure 1001 is integrally formed with the side plate, which greatly reduces the weld length in the dishwasher processing and improves the efficiency of product production.

[0214] The rounded corner connecting structure 1002 is angular. The bottom surface of the rounded corner connecting structure 1002 is an arc surface, which is consistent with the shape of the rounded corner transition side plate between the connected side plates. The end face shapes on both sides of the rounded corner connecting structure 1002 are consistent with the end face shapes of the adjacent straight connecting structure 1001. The end faces on both sides of the rounded corner connecting structure 1002 are spliced ​​with the adjacent straight connecting structure 1001. The top surface of the rounded corner transition side plate between the bottom surface and the side plate is spliced. After splicing, it folds outward towards the inner tank body 200. The weld only appears on the end face spliced ​​with the adjacent straight connecting structure and the top surface spliced ​​with the rounded corner transition side plate. The length of the weld is greatly reduced, and the overall aesthetics of the dishwasher are improved.

[0215] Combination Figure 1 , Figure 30 and Figure 33 The system includes a door body 301 and an inner liner body 200, which includes a front panel 201 near the door body 301. A straight connecting structure 1001 is provided with a connecting plate 10011 that is spliced ​​with the door body 301. The straight connecting structure 1001 is located on the top surface of the front panel 201 and is integrally formed with the front panel 201. The front panel 201 is connected to the door body 301 through the connecting plate 10011 on the straight connecting structure 1001. The connecting plate 10011 is located on the outer edge of the folding structure of the straight connecting structure 1001 that folds outward toward the inner liner. The outer edge of the folding structure is folded upward to form a long strip-shaped plate structure.

[0216] Combination Figure 1 , Figure 33 and Figure 34 Two outer panels 302 are located on both sides of the inner liner body 200, parallel to the stretching direction of the dishwasher. The inner liner body 200 also includes two side panels 203 parallel to the stretching direction of the dishwasher. A straight connecting structure 1001 is provided with an overlapping plate 10012 that splices with the outer panels 302. The straight connecting structure 1001 is set on the top surface of the side panel 203 and is integrally formed with the side panel 203. The straight connecting structure 1001 connected to the side panel 203 folds outward from the inner liner and then folds downward to form a perpendicular line to the door body 301. A plane parallel to the side panel 203 has its bottom surface folded towards the side panel 203 to form a horizontal overlapping plate 10012 perpendicular to the side panel 203. The side panel 203 is connected to the outer panel 302 through the overlapping plate 10012 of the flat connecting structure. This structure serves to connect the inner tub body 200 and the outer panel 302. At the same time, the flat connecting structure 1001 is made of stainless steel, which greatly improves the overall aesthetics of the dishwasher. In addition, the stainless steel material is easy to clean, resulting in a good user experience.

[0217] Combination Figure 1 , Figure 33 and Figure 31The inner liner body 200 also includes rounded corner transition side panels located between the front panel 201 and the side panel 203. The top surface of the rounded corner transition side panel is arc-shaped. The rounded corner connecting structure 1002 is provided with a downward arc-shaped flange. The bottom surface of the flange is connected to the top surface of the rounded corner transition side panel. The rounded corner connecting structure 1002 is also provided with a door connecting structure 10021 spliced ​​with the door body 301 and an overlapping plate 10022 spliced ​​with the side panel. The rounded corner connecting structure 1002 is spliced ​​with the rounded corner transition side panel, the adjacent straight connecting structure, the door body 301 and the outer panel 302.

[0218] The rounded corner connection structure 1002, which is connected to the top surface of the rounded corner transition side plate, is angular and has a first transition connection edge 10023 and a second transition connection edge 10024 that are perpendicular to each other and connected to two adjacent straight connection structures respectively. The first transition connection edge 10023 and the second transition connection edge 10024 are connected to each other. The door connection structure 10021, which is connected to the door body 301, is located at the transition junction of the first transition connection edge 10023 and the second transition connection edge 10024.

[0219] The first transition connecting edge 10023 is arranged perpendicular to the door body, and the second transition connecting edge 10024 is arranged parallel to the door body. The door body connecting structure 10021 is formed by turning outward at the end where the first transition connecting edge 10023 and the second transition connecting edge 10024 meet. Alternatively, in another embodiment of this embodiment, the door body connecting structure 10021 is formed by extending outward at the end where the second transition connecting edge 10024 meets the first transition connecting edge 10023.

[0220] The first transition connecting edge 10023 includes a first inner edge 100232 and a first outer edge 100231. The second transition connecting edge 10024 includes a second inner edge 100242 and a second outer edge 100241. The first outer edge 100231 and the second outer edge 100241 are perpendicularly connected. The first inner edge 100232 and the second inner edge 100242 are connected by an arc transition. The arc surface where the first inner edge 100232 and the second inner edge 100242 are connected by an arc transition is folded downwards. The bottom surface is connected to the top surface of the rounded corner transition side plate. The first outer edge 100231 is folded downwards to form a plane that is perpendicular to the door body 301 and parallel to the side plate 203. The door body connecting structure 10021 is formed by folding the plane of the first outer edge 100231 outwards. Alternatively, in another embodiment of this embodiment, it is formed by extending one end of the second outer edge 100241.

[0221] The bottom of the first outer edge 100231 is folded downwards towards the side panel 203 to form a horizontal overlapping plate 10022 perpendicular to the side panel 203. The overlapping plate 10022 of the rounded corner connection structure 1002 is connected to the outer panel 302 through the rounded corner transition side panel, and connected to the door 301 through the rounded corner transition side panel of the door connection structure 10021. The first inner edge 100232 and the second inner edge 100242 are respectively connected to the adjacent straight connection structure 1001. This structure not only connects the inner tank body 200 with the outer panel 302 and the door 301, but also uses stainless steel material for the rounded corner connection structure 1002, which greatly improves the overall aesthetics of the dishwasher. At the same time, the stainless steel material is easy to clean, and the user experience is good during use.

[0222] Combination Figure 1 , Figure 33 and Figure 35 The inner tank body 200 also includes a rear plate 202 opposite to the front plate 201. The straight connecting structure 1001 is disposed on the top surface of the rear plate 202. The straight connecting structure 1001 on the rear plate 202 is integrally formed with the rear plate 202. After being folded outwards towards the inner tank, it is folded vertically downwards to form a planar structure parallel to the rear plate 202. This structure can connect two connected rounded corner connecting structures 1002, making the connecting structure 100 on the opening of the inner tank a complete structure, thus improving the aesthetics of the dishwasher.

[0223] Combining 1, Figure 33 , Figure 36 and Figure 37 The inner liner body 200 also includes rounded corner transition side plates located between the rear plate 202 and the side plate 203. The rounded corner connecting structure 1002 is provided with an overlapping plate 10022 that splices with the outer plate 302. The rounded corner connecting structure 1002 splices with the rounded corner transition side plate, the adjacent straight connecting structure 1001, and the outer plate 302.

[0224] The rounded corner connection structure 1002, which connects to the top surface of the rounded corner transition side plate, is angular and similar to the rounded corner connection structures 1002 on both sides of the straight connection structure 1001 on the top surface of the front plate 201 described above. Here, the rounded corner connection structures 1002 on both sides of the straight connection structure 1001 on the top surface of the rear plate 202 have mutually perpendicular first transition connection edges 10023 and second transition connection edges 10024 that connect to two adjacent straight connection structures 1001 respectively. The first transition connecting edge 10023 is parallel to the rear plate 202, and the second transition connecting edge 10024 is perpendicular to the rear plate 202. The first transition connecting edge 10023 includes a first inner edge 100232 and a first outer edge 100231, and the second transition connecting edge 10024 includes a second inner edge 100242 and a second outer edge 100241. The first outer edge 100231 and the second outer edge 100241 are perpendicularly connected, and the first inner edge 100232 and the second inner edge 100241 are perpendicularly connected. 00242 is connected by an arc transition. The arc surface where the first inner edge 100232 and the second inner edge 100242 connect is folded downwards, and the bottom surface is connected to the top surface of the rounded corner transition side plate. The first outer edge 100231 is folded downwards to form a plane parallel to the rear plate 202, and the second outer edge 100241 is folded downwards to form a plane perpendicular to the rear plate 202. The bottom surface of the plane is folded towards the side plate 203 to form a horizontal overlapping plate 10022 perpendicular to the side plate 203, which is connected by rounded corners. The overlapping plate 10022 of the connecting structure 1002 with rounded corner transition side plate is connected to the outer plate 302. It is connected to the adjacent straight connecting structure 1001 through the first inner edge 100232 and the second inner edge 100242 respectively. This structure not only serves to connect the inner tank body 200 and the outer plate 302, but also the rounded corner connecting structure 1002 is made of stainless steel, which greatly improves the overall aesthetics of the dishwasher. At the same time, the stainless steel material is easy to clean, and the user experience is good during use.

[0225] Combination Figure 1 and Figure 38 The flat connecting structure 1001 and the rounded corner connecting structure 1002, which are connected to the front plate 201, the side plate 203, and the top surface of the rounded corner transition side plates on both sides of the side plate 203 of the inner tank body 200, have overlapping plates 10012 and 10022, which are provided on the outer plate 302. The grooves are recessed in the direction of the inner tank opening. The top surface of the outer plate 302 has a protruding structure that matches the grooves on the overlapping plates 10012 / 10022. The outer surface of the protruding structure has the same shape as the inner surface of the recessed groove. The protruding structure is embedded in the groove. In this embodiment, the cooperation between the groove and the protruding structure greatly reduces the connection gap between the outer plate 302 and the overlapping plate, preventing the outer plate 302 from shifting and generating noise during the operation of the dishwasher.

[0226] Example 11

[0227] like Figure 39 As shown, the main difference between this embodiment and embodiment ten is that the connecting structure 100 connected to the top surface of the opening of the inner liner body 200 is different. The connecting structure 100 in this embodiment includes a straight connecting structure 1001 connected to the front plate 201 and the rear plate 202 of the inner liner body 200 respectively. Preferably, the straight connecting structure 1001 is integrally formed with the front plate 201 / rear plate 202. The connecting structure 100 also includes a U-shaped connecting structure 103 connected to the side plate 203 of the inner liner body 200 respectively. The overall shape of the U-shaped connecting structure 103 is consistent with the overall shape formed by the straight connecting structure 1001 connected to the top surface of the side plate 203 and the rounded corner connecting structures 1002 located on both sides of the straight connecting structure 1001 in embodiment ten. The U-shaped connecting structure 103 is an integrally formed structure. The U-shaped connecting structure 103 is also provided with an overlapping plate connected to the outer plate 302. The overlapping plate is provided with a groove that cooperates with the protrusion on the top surface of the outer plate 302.

[0228] Example 12

[0229] like Figure 40 As shown, this embodiment introduces another connection form between the connecting structure 100 and the inner liner body 200. The main difference from Embodiment Eleven is that the connecting structure 100 connected to the top surface of the side plate 203 of the inner liner body 200 is different. In this embodiment, the U-shaped connecting structure 103 and the outer plate 302 in Embodiment Three are integrally formed from a single plate, eliminating the overlapping plate under the U-shaped connecting structure 103 and the part where the top surface of the outer plate 302 mates with the overlapping plate. In Embodiment Two, the door connecting structure 10021 and the side plate connecting plate 3021 are formed by folding a single plate away from the inner liner body 200. The connection relationship between the door connecting structure 10021 and the side plate connecting plate 3021 and the door 301 in Embodiment Ten is the same. This structure further reduces the number of assembly parts of the dishwasher, reduces the welding process in the dishwasher assembly process, and improves assembly efficiency.

[0230] The following examples, thirteen and fourteen, illustrate the relevant structural features of the cooperation between the inner liner body 200 and the base 500.

[0231] Example 13

[0232] During the stretching process of the dishwasher, the inner tub body 200 is easily separated from the base support 500. Therefore, in this embodiment, a support structure 506 that cooperates with the inner tub body 200 is provided on the base support 500 to increase the stability between the inner tub body 200 and the base support 500.

[0233] like Figure 1 and Figure 41As shown, the dishwasher inner tub structure provided in this embodiment includes: an inner tub body 200, the inner tub body 200 including a bottom wall 210 and a peripheral wall 220; a bottom support 500, the bottom support 500 being located below the inner tub body 200 and used to support the bottom of the inner tub body 200; the dishwasher is stretched by a slide rail, the outer wall of the bottom support 500 is provided with a clearance structure that avoids the slide rail and cooperates with the slide rail, and the inner wall of the bottom support 500 is provided with a support structure 506 corresponding to the clearance structure for supporting the inner tub body 200.

[0234] like Figure 43 and Figure 44 As shown, the avoidance structure is provided on both outer sides of the base 500 parallel to the stretching direction of the dishwasher. Specifically, the avoidance mechanism is a slide rail groove 600 provided on both outer sides of the base 500. The slide rail groove 600 cooperates with the slide rail on the dishwasher. The inner wall of the base 500 is provided with a support structure 506 corresponding to the position of the slide rail groove 600, which cooperates with the inner tub body 200.

[0235] Specifically, the base 500 includes a base plate 502 and base sidewalls 503. The base sidewalls 503 are arranged circumferentially around the base plate 502 to form a receiving space that can accommodate the bottom of the inner tub body 200. The two base sidewalls 503 parallel to the stretching direction of the dishwasher are fixedly provided with upwardly recessed slide rail grooves 600. The inner wall of the base sidewalls 503 is provided with a support structure 506 corresponding to the slide rail grooves 600 to cooperate with the bottom of the inner tub body 200. In order to better support the inner tub body 200, multiple support structures 506 are arranged at intervals on the inner walls of the two base sidewalls 503 parallel to the stretching direction of the dishwasher. The support structures 506 not only support the inner tub body 200, but also play a role in transmitting force between the base 500 and the inner tub body 200 when the dishwasher is stretched, thereby increasing the stability between the inner tub body 200 and the base 500.

[0236] In this embodiment, the support structure 506 is a support platform provided at the bottom of the base sidewall 503. To improve the support stability of the support platform for the inner liner body 200, a large number of support platforms are provided. The support platforms are evenly distributed circumferentially on the inner wall of the base sidewall 503. Each support platform includes a flat portion 5061 integrally formed with the base sidewall 503. The bottom wall 210 of the inner liner body 200 is located on the flat portion 5061 of the support platform, and the top of the support platform is in contact with the bottom surface of the inner liner body 200. By making the top of the support platform a surface, the contact area between the support platform and the bottom of the inner liner body 200 is increased, thereby improving the effectiveness and stability of the support provided by a single support platform.

[0237] like Figure 42As shown, the planar portion 5061 includes a plane formed by a straight section 50611 and U-shaped curved sections 50612 connected to both ends of the straight section 50611. The straight section 50611 is fixedly connected to the inner wall of the base side wall 503.

[0238] Specifically, such as Figure 44 As shown, the bottom support sidewall 503 of this embodiment includes a vertical plate 5031 and an inclined plate 5032 that extends from the upper end of the vertical plate 5031 to the outside of the inner liner. The inclined plate 5032 is arranged circumferentially around the upper edge of the vertical plate 5031 to form a receiving space with an upper opening that radiates outward. The bottom of the inner liner body 200 is located in the receiving space of the bottom support 500. In this embodiment, the straight section 50611 of the planar portion 5061 of the support structure 506 is horizontally fixed on the inner wall of the inclined plate 5032. The support platform also includes a reinforcing rib 5062 integrally formed with the planar portion 5061. The reinforcing rib 5062 is a support surface that extends vertically downward along the outer edge of the U-shaped curved section 50612 of the planar portion 5061 and is fixedly connected to the inner wall of the inclined plate 5032. The reinforcing rib 5062 strengthens the stability of the support platform and prevents the support platform from bending or deforming when the base 500 is supported by the inner liner body 200.

[0239] like Figure 46 As shown, to further improve the stability of the fit between the support structure 506 and the bottom of the inner liner body 200, a positioning structure 700 that cooperates with the support structure 506 is provided at the junction of the bottom wall 210 and the peripheral wall 220 of the inner liner body 200, increasing the stability between the inner liner body 200 and the base 500. Through the positioning structure 700, the top of the support structure 506 can stably abut against the bottom of the inner liner body 200. Even when the inner liner body 200 vibrates, the support structure 506 will not detach from the bottom of the inner liner body 200, thus significantly increasing the support stability of the support structure 506.

[0240] Specifically, the positioning structure 700 is a molded structure recessed into the interior of the inner liner body 200 at the connection between the bottom wall 210 and the peripheral wall 220 of the inner liner body 200. The shape and size of the molded structure match those of the support structure 506. The support structure 506 engages with the recessed surface of the lower surface of the molded structure, and the protruding surface of the upper surface of the molded structure supports the shelves inside the inner liner body 200. In this embodiment, the positioning structure 700 is a molded structure formed directly by a stamping process, which is simple to manufacture. Furthermore, the formed molded structure not only cooperates with the support structure 506 to prevent the bottom support 500 from detaching from the inner liner body 200, but also serves to support the shelves and dish racks inside the dishwasher, making it a multi-functional device.

[0241] To reduce the transmission of vibration and noise during the sliding process of the inner tub body 200, a shock-absorbing structure is provided on the support platform. This structure consists of rubber shock-absorbing pads that adhere to the outer surface of the support platform. When vibrations from the inner tub body 200 are transmitted to the support platform, the elasticity of the rubber shock-absorbing pads buffers and absorbs the vibrations, effectively blocking the transmission of vibrations and thus reducing noise generation, which helps to lower the noise level of the dishwasher.

[0242] Furthermore, in combination Figure 41 A waterproof structure 501 is provided at the position where the base 500 connects to the inner liner body 200 to prevent water leakage from the inner liner. Specifically, a connecting structure for connecting the inner liner body 200 is provided on the side wall 503 of the base. The waterproof structure 501 is arranged around the connecting structure to form circumferential waterproofing to the bottom of the inner liner body 200.

[0243] Combination Figure 41 , Figure 43 and Figure 44 The connecting structure is located on the top of the bottom support side wall 503. The waterproof structure 501 is a water-blocking rib located on the bottom support side wall 503, with its bottom surrounded by the connecting structure. The water-blocking rib is located on the outer edge of the top of the bottom support side wall 503 and extends circumferentially around the top of the bottom support side wall 503. The connecting structure is located on the inner edge of the top of the bottom support side wall 503 and is spaced circumferentially around the top of the bottom support side wall 503. There is a gap between the waterproof structure 501 and the connecting structure, which allows water to flow through the gap between them and collect back into the bottom support cavity.

[0244] Specifically, the connecting structure consists of guide ribs 504 located on the top of the side wall of the base tray. The side surface of the guide ribs 504 near the center of the base tray is in contact with the outer wall surface of the inner tank body 200. Multiple guide ribs 504 are spaced circumferentially around the top of the side wall. When placing the inner tank body 200, they provide installation guidance, improving the assembly efficiency of the dishwasher. Simultaneously, the spaced guide ribs facilitate the return of collected water flow from the gaps between the guide ribs 504 to the receiving cavity of the base tray 500. The top of the base tray side wall 503 extends outwards to form an annular plane surrounding the interior of the base tray. The water-blocking ribs are located at the outer edge of the annular plane, and the guide ribs 504 are located at the inner edge of the annular plane. The annular plane is formed by bending and extending the top surface of the base tray side wall 503 outwards from the base tray 500. The water-blocking ribs are located at the outer edge of the annular plane.

[0245] like Figure 44 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.

[0246] 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.

[0247] Specifically, such as Figure 45 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.

[0248] 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.

[0249] Example 14

[0250] This embodiment provides a specific connection method between the base 500 and the inner liner body 200.

[0251] like Figure 47 As shown, a dishwasher inner tub structure includes a base 500 and an inner tub body 200 disposed on the base 500. A fixing structure is provided on the inner tub body 200, and the inner tub body 200 is fixedly connected to the base 500 through the fixing structure. The fixing structure is a base connecting plate 2001 disposed at the bottom of the inner tub body 200 and extending outward from the inner tub body 200, and the base connecting plate 2001 is fixedly connected to the base 500. Preferably, the base connecting plate 2001 is arranged around the bottom perimeter of the inner tub. The base connecting plate 2001 serves both as a fixing structure to fix the inner tub body 200 and the base 500, and as a sealing structure to seal the space between the inner tub body 200 and the base 500, preventing water leakage from the inner tub body 200 from overflowing from the base 500, thus improving the user experience.

[0252] Furthermore, the inner liner body 200 is composed of an annular side plate and a bottom plate spliced ​​together. The bottom support connecting plate 2001 is formed by extending from the outer wall of the annular side plate to the outer side of the inner liner body 200, and / or by extending from the peripheral wall of the bottom plate to the outer side of the inner liner body 200, and / or by extending from the splicing position of the annular side plate and the bottom plate to the outer side of the inner liner body 200.

[0253] Furthermore, the annular side plate and the bottom plate are connected by a splicing structure. The splicing structure is formed by the first connecting surface and the second connecting surface, which are formed by bending and extending the edges of the side plate and the bottom plate outwards from the inner liner respectively. The splicing structure serves as the bottom support connecting plate 2001 and is fixedly connected to the side wall of the bottom support. The splicing structure serves as the bottom support connecting plate 2001, which saves the process of remanufacturing the bottom support connecting plate 2001 and connecting the bottom support connecting plate 2001 to the inner liner body 200, thereby increasing the production efficiency of the dishwasher inner liner structure.

[0254] Furthermore, it also includes a connector that fixes the inner liner body 200 to the base 500. The connector has mounting holes, and the connector passes through the mounting holes and is fixedly connected to the base to fix the inner liner body 200 to the base 500.

[0255] Preferably, the connecting member is a connecting bolt, and the base 500 has a screw hole for assembly with the connecting bolt.

[0256] Furthermore, the inner wall of the base 500 is provided with a connecting boss 5033 that cooperates with the base connecting plate 2001. The connecting boss 5033 and the base connecting plate 2001 are fastened together by a connector. The setting of the connecting boss 5033 is conducive to the connection and fixation of the base connecting plate 2001 and the base 500, and increases the assembly efficiency.

[0257] Furthermore, the base 500 includes a base side wall 503 and a base plate 502. The base side wall 503 and the base plate 502 together form a cavity for accommodating the bottom of the inner liner body 500. The connecting boss 5033 is provided on the base side wall 503 or the base plate 502 and is set at a height higher than the bottom plate of the inner liner body 200.

[0258] Preferably, the connecting boss 5033 is disposed on the side wall 503 of the base support and is disposed corresponding to the mounting hole on the base support connecting plate 2001.

[0259] Furthermore, the connecting boss 5033 is formed by bending and extending the bottom support sidewall 503 inward into the bottom support.

[0260] Furthermore, the bottom support sidewall 503 is also provided with a waterproof structure 501. The waterproof structure 501 is formed by extending upward from the free end of the bottom support sidewall 503. The waterproof structure 501 is set higher than the connecting boss 5033 to prevent water leakage from the inner liner. The waterproof structure 501 is described in detail in Embodiment Thirteen, and will not be repeated here.

[0261] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention.
