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 people's living standards improve, more and more families are using dishwashers to wash dishes. Previously, front-opening dishwashers required users to bend over significantly or even squat to fully open the door, which was tiring. Furthermore, without any surrounding support, residual food or liquids could easily spill outside the dishwasher, resulting in a poor user experience. With advancements in dishwasher technology, drawer-type dishwashers were invented. These dishwashers use a pull-out door design, eliminating the need for bending over or squatting, making them more ergonomic. The surrounding design also prevents spills. The inner tank structure of a drawer-type dishwasher includes a main body with a top-opening cavity. This main body can be formed by a single stamping and stretching process or by splicing multiple parts. However, considering that a single-piece stamping and stretching process for a stainless steel inner tank results in poor structural consistency, some rounded corners are prone to deformation, and controlling the overall dimensions of the stainless steel inner tank is difficult. From a materials and manufacturing process perspective, the thickness of the stainless steel drawn inner tank material is related to the drawing depth. The deeper the drawing, the thicker the material is required. Furthermore, drawing the inner tank can lead to uneven wall thickness, and deep drawing molding is difficult and has low production efficiency. Therefore, a manufacturing method that uses multiple components assembled together to form the main body of the dishwasher inner tank is more feasible.

[0003] The manufacturing method of dishwasher inner tub body formed by splicing multiple parts usually involves first stamping the bottom of the inner tub body in one piece, and then connecting the annular side plate to the bottom of the inner tub body. When stamping the bottom of the inner tub body, a die-pulling angle needs to be set to consider demolding. However, the bottom of the dishwasher inner tub body needs to be equipped with a filter screen. If the filter screen is set too small, it is easy to cause secondary pollution. Therefore, how to set the die-pulling angle to take into account both demolding and the setting of the filter screen is a problem that those skilled in the art need to consider and solve.

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

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a dishwasher inner tank structure.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is: a dishwasher inner tank structure, including an inner tank body with an opening at the top, the inner tank body including an inner tank bottom, the inner tank bottom including an inner tank bottom wall and an inner tank bottom side wall surrounding the inner tank bottom wall, the inner tank bottom side wall and the inner tank bottom wall are transitionally connected, the inner tank bottom side wall is inclined to the outside of the inner tank body, a certain transition inclination angle is formed between the inner tank bottom side wall and the normal of the inner tank bottom wall, and at least one of the inner tank bottom side walls and the inner tank bottom wall has a smaller transition inclination angle than the other inner tank bottom side walls and the inner tank bottom wall.

[0007] Furthermore, the inner liner body is connected to a door, and the bottom sidewall of the inner liner includes a front wall of the inner liner bottom near the door. The transition angle between the front wall of the inner liner bottom and the bottom wall of the inner liner bottom is smaller than the transition angle between the other bottom sidewalls of the inner liner bottom and the bottom wall of the inner liner bottom.

[0008] Furthermore, the inner liner bottom sidewall includes an inner liner bottom left wall and an inner liner bottom right wall connected to the two ends of the inner liner bottom front wall, and an inner liner bottom rear wall opposite to the inner liner bottom front wall. The transition tilt angle between the inner liner bottom front wall and the inner liner bottom wall is smaller than the transition tilt angle between the inner liner bottom left wall and the inner liner bottom wall, the transition tilt angle between the inner liner bottom right wall and the inner liner bottom wall, and the transition tilt angle between the inner liner bottom rear wall and the inner liner bottom wall.

[0009] Preferably, the transition angle between the left wall and the bottom wall of the inner liner, the transition tilt angle between the right wall and the bottom wall of the inner liner, and the transition tilt angle between the rear wall and the bottom wall of the inner liner are all the same.

[0010] Furthermore, the bottom wall of the inner liner is provided with a mounting position for installing a filter screen on the side near the front wall of the inner liner bottom.

[0011] Preferably, an installation port for installing a sprayer is provided at the center of the bottom wall of the inner liner, and the installation position is located between the installation port and the front wall of the bottom of the inner liner.

[0012] Furthermore, it also includes a base support for supporting the inner liner body, wherein the base support is provided with a slide rail groove for installing slide rails, and the transition inclination angle between the inner liner bottom side wall corresponding to the slide rail groove and the inner liner bottom wall is greater than the transition inclination angle between other inner liner bottom side walls and the inner liner bottom walls.

[0013] Furthermore, the slide rail grooves are respectively set on both sides of the bottom support corresponding to the left and right walls of the inner liner bottom.

[0014] Furthermore, a dishwasher water passage is provided on the outside of the bottom rear wall of the inner liner, and the transition angle between the bottom rear wall of the inner liner and the bottom wall of the inner liner avoids the dishwasher water passage.

[0015] Furthermore, the inner liner body also includes a side peripheral wall surrounding the bottom of the inner liner, and a connecting part that connects to the bottom side wall of the inner liner is provided at the lower edge of the side peripheral wall.

[0016] The connecting part includes a connecting surface that connects to the corresponding bottom support side wall. The connecting surface is parallel to one side of the corresponding inner liner bottom side wall and is fitted to one side of the inner liner bottom side wall.

[0017] 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 inner liner bottom side wall. One end of the inner liner bottom side wall abuts against the limiting surface, and one side of the inner liner bottom side wall is attached to the connecting surface.

[0018] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0019] This invention employs a manufacturing method for the dishwasher inner tub body formed by assembling multiple components, avoiding the molding difficulties and material waste caused by the one-piece stamping and stretching molding method. The assembly components include the inner tub bottom, which is formed by one-piece stamping. During the one-piece stamping process, a draft angle is set for demolding, i.e., the excessive inclination angle between the bottom wall and side wall of the inner tub bottom. A filter screen needs to be installed on the side of the inner tub bottom wall near the front wall. The filter screen area should be as large as possible; otherwise, an excessively small filter screen may cause secondary contamination. Therefore, the excessive inclination angle between the bottom wall and front wall of the inner tub bottom should be as small as possible to ensure sufficient installation space for the filter screen and avoid secondary contamination.

[0063] like Figure 1 As shown, this invention provides a dishwasher inner tank structure, mainly applied to drawer-type dishwashers. Compared to front-opening dishwashers, which require significant bending or even squatting to fully open the door, making them more tiring for users, and because there is no surrounding enclosure when placing dishes in a front-opening dishwasher, residual soup or water can easily spill outside the dishwasher, undoubtedly resulting in a poor user experience. Drawer-type dishwashers use a pull-out door design, eliminating the need for significant bending or squatting, making them more ergonomic. Furthermore, the surrounding enclosure design prevents spillage of residual soup or water. The dishwasher inner tank structure includes an inner tank body 200 and an outer panel disposed on the outside of the inner tank body. A base support 500 is installed at the bottom of the inner tank body 200, and a bottom cover 400 is disposed between the bottom of the inner tank body 200 and the base support 500. The following embodiments illustrate the structure and connection relationships of the various parts of the dishwasher inner tank structure of this invention.

[0064] The inner liner body 200 of the present invention can be integrally molded or assembled from multiple parts.

[0065] This invention provides several different methods for manufacturing the inner drum body 200. The following examples illustrate how the dishwasher inner drum body 200 is manufactured.

[0066] Example 1

[0067] In this embodiment, the inner liner body 200 is made by splicing three parts together, and the specific splicing method is as follows.

[0068] like Figure 2 As shown, the inner liner body 200 is formed by splicing at least two parts. The splicing positions between the parts are located on a plane, which greatly reduces the difficulty of the welding process during assembly and improves the assembly efficiency.

[0069] In this invention, the dishwasher inner liner body 200 is composed of three parts spliced ​​together, including a first part, a second part and a third part. The second part and the third part are located on both sides of the first part and are parallel to the pull-out direction of the dishwasher. The splicing position of the second part / third part and the first part is located on a plane.

[0070] The first component includes a bottom wall 204 of the inner liner body and a front wall 201 and a rear wall 202 connected to the bottom wall 204 and perpendicular to the dishwasher's pull-out direction.

[0071] The second / third component includes a sidewall 203 parallel to the dishwasher's pull-out direction. The second / third component also includes an extension that bends toward the opposite sidewall and is connected to the sidewall 203. The extension is connected to the first component, and the extension and the sidewall 203 are smoothly connected by a rounded corner structure. The extension avoids connecting the second / third component and the first component on a curved surface, and instead places the joint on a plane, thereby reducing the difficulty of welding.

[0072] The second / third component is integrally formed by stamping. The extension includes a first extension surface 2031 located on the bottom surface of the side wall 203 and a second extension surface 2032 located on the side surface of the side wall 203. The first extension surface 2031 and the second extension surface 2032 are connected by a rounded corner structure. The second extension surface 2032 extends straight towards the opposite side wall. The first extension surface 2031 is connected to the bottom wall 204 in the first splicing component, and the second extension surface 2032 is connected to the front wall 201 / rear wall 202 in the first splicing component.

[0073] like Figure 3The image shows a front view of the inner liner body 200 of the present invention. The dishwasher is pulled out by a slide rail. The side wall 203 of the second / third component includes a recessed surface 2033. The recessed surface 2033 is a receiving part that is recessed towards the center of the inner liner. The receiving part can be fitted with a slide rail to facilitate pulling out the dishwasher and taking out and putting in the tableware in the dishwasher.

[0074] Example 2

[0075] Unlike Embodiment 1, in this embodiment, the inner liner body 200 is formed by bending a plate into the inner liner side wall 220, and the side wall 220 is spliced ​​with the bottom wall of the inner liner. The specific splicing method is as follows.

[0076] like Figure 9 and Figure 10 As shown, the inner liner body 200 includes an inner liner bottom wall 204 and an inner liner side peripheral wall 220. The inner liner bottom wall 204 and the inner liner side peripheral wall 220 form an inner liner body 200 with an upward opening. The inner liner side peripheral wall 220 is a single plate that is bent and rolled into a ring. One end of the plate has a splicing part 221, and the other end overlaps the splicing part 221. The splicing positions 222 at both ends are located on a plane. This eliminates the influence of dimensional errors on the assembly structure, facilitates welding of splicing components with determined final dimensions, results in neat welds, simplifies the welding surface treatment process, and improves the manufacturing efficiency of the dishwasher.

[0077] like Figure 10 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 10 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 9 As shown, the inner liner sidewall 220 includes four straight sidewalls with rounded corner transitions between them. The splicing position is located on the straight sidewalls. The straight sidewalls include a front wall 201, a rear wall 202, and two side walls 203 located on both sides of the front wall. Preferably, the splicing position is located on the front wall 201.

[0085] like Figure 9 As shown, the inner liner bottom wall 204 includes the inner liner bottom wall and the inner liner bottom side wall 211 formed by folding the edge of the inner liner bottom wall upward. The inner liner bottom wall 204 is an upward-opening structure with a small accommodating cavity. The bottom surface of the inner liner side peripheral wall 220 is spliced ​​with the top surface of the inner liner bottom wall 204.

[0086] In this embodiment, 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.

[0087] Example 3

[0088] Unlike the above embodiments, in this embodiment, the inner liner body 200 is formed by bending a single plate integrally, and the specific formation method is as follows.

[0089] like Figure 8 As shown, the inner liner body 200 includes a bottom wall 204 and a side panel assembly. The bottom wall 204 and the side panel assembly are an integral piece. The side panel assembly is bent and spliced ​​to form the side peripheral wall 220 of the dishwasher.

[0090] In this embodiment, the inner liner body 200 is formed by bending an integral sheet metal, which reduces the weld length and simplifies the processing technology.

[0091] Preferably, the bottom wall 204 has multiple sides, and the side panel assembly includes plates that are respectively connected to each side of the bottom wall 204. Each plate is bent toward the same side of the bottom wall 204 to form the side peripheral wall 220 of the dishwasher.

[0092] In the above solution, the solution of the present invention can produce inner tank bodies 200 of different shapes, bend each plate relative to the bottom wall 204, and splice adjacent two plates to form a ring-shaped side wall 220 of the dishwasher.

[0093] Preferably, the bottom wall 204 is a quadrilateral plate, and each of the four sides of the quadrilateral plate is connected to a plate body. The four plates body are bent toward the same side of the bottom wall 204 to form the side wall 220 of the dishwasher. The opposite sides of two adjacent plates body are in contact and connected by a set process.

[0094] Preferably, the opposite sides of two adjacent plates are in contact and welded together.

[0095] Preferably, in the inner liner body 200, one of the two adjacent plates has a connecting part on its side, and the plate is connected to the other plate through the connecting part.

[0096] Preferably, the connecting part includes a flange provided on one side edge of the plate. After both plates are bent relative to the bottom wall 204, the side edge of one plate is attached to the flange of the adjacent plate.

[0097] 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 limitation for the other plate, which facilitates the welding process.

[0098] The flange is formed by bending the edge of the panel towards the plane containing the adjacent panel. When the inner liner body 200 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 spliced ​​with, or away from the panel it is spliced ​​with.

[0099] like Figure 3 He Ru Figure 8 As shown, the inner liner includes two first plates 8001 disposed on opposite sides of the bottom wall 204, and two other plates of the inner liner are second plates 8002. The bottom of the two 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 wall 204, the edges of the two second plates 8002 are attached to the flanges.

[0100] 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.

[0101] Preferably, the first plate 8001 is stamped to form a recessed surface 2033 / 2035 that gradually narrows towards the bottom wall 204 and connects to the bottom wall 204. The second plate 8002 is stamped to form a recessed surface 2033 / 2035 that gradually narrows towards the bottom edge and connects to the bottom wall 204. 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.

[0102] In addition, this embodiment also provides a method for manufacturing the dishwasher inner drum body 200 in Embodiment 1, including the following steps:

[0103] S1. Stamp an integral bottom wall 204 and side panel assembly onto the sheet metal according to the inner liner dimensions;

[0104] S2. Bend the plates in the side panel assembly to form the side wall of the dishwasher;

[0105] S3. Connect and fix the various plates together using a connection process.

[0106] Preferably, a quadrilateral bottom wall 204 and four plates respectively connected to the four sides of the bottom wall 204 are stamped on the sheet material. Each plate is bent vertically toward the same side of the bottom wall 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.

[0107] Preferably, in step S1, a recessed surface 2033 is punched out at the bottom of the two plates on both sides of the bottom wall 204 along the bending direction of the plates.

[0108] Alternatively, in step S1, a convex mold is formed on each of the two plates on both sides of the bottom wall 204, with the convex mold forming on the side opposite to the bending direction of the plate, and the recessed surface 2035 is formed between the bottom surface of the mold and the bottom edge of the plate.

[0109] The specific structure of the inner liner body 200 is described below through several embodiments.

[0110] Example 4

[0111] The following will describe the installation port of the detergent adding device on the inner tank body 200 and the specific location of the installation port.

[0112] like Figure 7 As shown, the inner liner body 200 includes a bottom wall 204 and a side wall 220. The side 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 the side wall 220. 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.

[0113] 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. The notch forms an installation port 2011 for placing a detergent adding device when splicing. The size of the notch can be set to different sizes and shapes according to the size of the detergent adding device.

[0114] 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.

[0115] As an alternative to the above solution, a notch can also be provided on one side of the first splicing surface or the second splicing surface. For example, a notch can be provided on one side of the first splicing surface. When the first splicing surface and the second splicing surface are spliced, the notch portion of the first splicing surface and the second splicing surface form an installation port 2011 that can be used to place a detergent adding device.

[0116] In this embodiment, an installation port 2011 for placing a detergent additive device is formed at the splice seam 2014, which reduces the length of the weld seam and can even eliminate the intermediate weld seam, thus reducing welding steps and saving costs.

[0117] In this embodiment, the bottom wall 204 has an upward-opening accommodating space. The open end of the bottom wall 204 is connected to the bottom edge of the side wall 220 to form the inner liner body. The bottom edge of the side wall is located above the water level inside the inner liner to minimize water leakage.

[0118] 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 body 200.

[0119] Preferably, a sealing ring 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.

[0120] Example 5

[0121] This embodiment will describe the specific structure of the bottom wall 204 of the inner liner. In this embodiment, the bottom wall 204 of the inner liner body 200 is tapered towards the bottom of the inner liner, facilitating the collection of water within the inner liner body 200. Specifically, the lower edge of the side peripheral wall 220 is circumferentially arranged around the outer edge of the bottom wall 204 to form a receiving cavity with a top opening. The bottom wall 204 is inclined downward along the lower edge of the side peripheral wall 220, forming a tapered shape that converges towards the bottom of the inner liner, facilitating the downward collection of water within the inner liner body 200.

[0122] Furthermore, such as Figure 11 As shown, a drain hole 2041 is provided on the bottom wall 204 of the inner liner. The drain hole 2041 is located below the plane where the lower edge of the side wall 220 is located. The drain hole 2041 and the plane where the lower edge of the side wall 220 is located form a certain height difference, which facilitates the downward discharge of water. The bottom wall 204 extends downward along the lower edge of the side wall 220 towards the drain hole 2041. The bottom wall 204 is in a converging shape towards the drain hole 2041, which facilitates the water in the inner liner to flow into the drain hole 2041 and be discharged.

[0123] In this embodiment, the bottom wall 204 includes four straight surfaces 2042 that are inclined and connected 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.

[0124] The preferred bottom wall 204 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 204.

[0125] In this embodiment, the through hole 2041 can be located at any position on the bottom wall 204. 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 204, the transition surface 2043 can be located at the centerline of the bottom wall 204, the through hole 2041 is the center hole located at the intersection of the centerlines of the bottom wall 204, and the flat surface 2042 is located between two adjacent transition surfaces 2043.

[0126] As a more preferred embodiment of the above solution, the transition surface 2043 is located at the diagonal of the bottom wall 204 of the inner liner, the through hole 2041 is the central hole located at the intersection of the diagonals of the bottom wall 204, 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 two adjacent flat surfaces 2042, which would contaminate the internal space of the dishwasher and make it difficult to clean.

[0127] Specifically, 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 204, and the two sides of the right-angled side 20431 form part of the outer edge of the bottom wall 204. 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 204. 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.

[0128] 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 204 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.

[0129] 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.

[0130] 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.

[0131] The dishwasher inner tank bottom wall 204 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 204 formed by stamping not only strengthens the structure of the inner tank itself, but also facilitates the flow of water to the center.

[0132] As a variation of this embodiment, the bottom wall 204 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 204 is formed by splicing four plates symmetrically arranged along the diagonal of the bottom wall 204 towards the through hole 2041. The edges of the plates form radial ribs at the diagonal positions of the bottom wall 204 to facilitate water flow collection.

[0133] Example 6

[0134] 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 204 or the side wall 220 of the inner tub body 200 may obstruct the movement of the spray arm, thus limiting the spray range and resulting in poor washing effect and incomplete cleaning of the dishwasher.

[0135] 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.

[0136] An obstacle avoidance structure 2003 for avoiding the dishwasher's internal spray nozzle is provided inside the inner tank body 200, combined with... Figures 12 to 16 As shown, 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 204. The bottom of the inner liner body 200 is provided with a avoidance structure 2003 for avoiding the sprayer.

[0137] Specifically, such as Figure 12 and Figure 13 As shown, the avoidance structure 2003 described in this embodiment is a molded structure disposed at the bottom of the inner liner body 200. The molded structure is used to avoid the sprayer, and the molded structure is a recessed surface at the junction of the bottom wall 204 and the side peripheral wall 220 that is recessed towards the outside of the inner liner body 200. Figure 14 and Figure 15 As shown, the molding structure is located at the midline endpoints on both sides of the bottom wall 204. The molding structure expands outward to avoid the two end arms of the sprayer, thereby expanding the spray range and avoiding the formation of washing dead corners during the spraying process, which would lead to poor washing effect and incomplete cleaning of the dishwasher.

[0138] In the above scheme, the bottom wall 204 can be square, and the forming structure is set at the midpoint of the four sides of the square bottom wall. The bottom wall 204 can also be rectangular, and the outer edge of the bottom wall 204 includes two long sides and two short sides arranged opposite to each other. The forming structure is set at the midpoint of the two long sides.

[0139] like Figure 16 As shown, in this embodiment, the molding structure is arc-shaped or crescent-shaped and recessed outward from the inner liner body 200. The shape of the molding structure matches the rotation trajectory of the spray arm end of the sprayer.

[0140] In order to achieve the purpose of expanding the capacity of the inner liner body 200, the side walls of the inner liner body 200 in Embodiments 1 to 6 are all provided with outward convex structures.

[0141] Example 7

[0142] This embodiment will describe the protruding structure provided on the side peripheral wall 220 of the inner liner body 200. For example... Figure 1-5 As shown, the inner liner body 200 includes a bottom wall 204 and a side wall 220 of the inner liner body 200, which is disposed on the bottom wall 204 and surrounds the bottom wall to form a side wall 220 of the inner liner body 200. The side wall 220 is configured as an outward protruding structure that protrudes from the inside of the inner liner body 200 to the outside.

[0143] In the above scheme, the side wall 220 of the inner liner body 200 is set as a structure that bulges outward from the inside of the inner liner, which increases the capacity of the inner liner and realizes the expansion of the inner liner.

[0144] Preferably, the inner drum body 200 is slidably disposed within the shell or bracket of the dishwasher, and the side peripheral wall 220 includes two side walls 203 extending along the sliding direction of the inner drum, and both side walls 203 are configured as outwardly convex structures protruding away from the opposite side wall.

[0145] In the above scheme, both sidewalls are designed to be convex structures, thereby increasing the size of the inner liner in a direction perpendicular to the sliding direction of the inner liner and increasing the internal space of the inner liner body 200.

[0146] The inner liner body 200 is composed of a bottom plate and a side plate assembly surrounding the bottom plate. The side plate assembly includes a front plate corresponding to the front wall, a rear plate corresponding to the rear wall, and a side plate corresponding to the side wall, forming a side peripheral wall 220. The middle part of the side plate protrudes outward, and the side plates bend and extend to the front plate and the rear plate respectively on both sides along the sliding direction of the inner liner.

[0147] In the above scheme, the side panel configuration is obtained by stamping a large area in the middle of the side panel, forming a structure that protrudes in the middle and recedes around the periphery, thereby increasing the internal space of the inner liner body 200. Specifically, an outwardly convex molding 2034 is stamped on the side panel in the opposite direction to the opposite side panel, forming a shell structure in which the bottom wall 204 protrudes outward and the peripheral wall extends towards the opposite side panel. In this method, stamping a large area in the middle of the side panel increases the internal space of the inner liner.

[0148] Preferably, the side panels are provided with second extension surfaces 2032 on both sides along the sliding direction of the inner liner, bending towards the front wall 201 and the rear wall 202 respectively to connect the front panel and the rear panel. The middle part of the side panel is a planar structure, and the two sides of the planar structure are smoothly connected to the corresponding side's second extension surface 2032 through a first arc surface. The middle part of the side panel is stamped into a convex plane, and the planar arc surface transitions to the side edge of the side panel. This reduces the stamping strength of the side panel, resulting in a high-strength, high-quality inner liner. The smoothly transitioned inner liner body 200 has a good overall gloss and a beautiful appearance. Through the design on the first extension surface, the joint position is shifted from the corner between the side panel and the front and rear panels to the plane where the front or rear panel is located, simplifying the connection between the side panel and the front and rear panels.

[0149] The middle part of the side panel is flat, and the flat surface transitions smoothly to the edge of the side panel on both sides along the sliding direction of the inner liner through a first arc. The curved surface of the middle part of the side panel transitions to the side edge of the side panel, which reduces the stamping strength of the side panel, resulting in a strong and high-quality inner liner. The smooth transition of the inner liner also results in a good overall gloss and beautiful appearance.

[0150] In this embodiment, the inner liner body 200 has a drawer structure. The inner liner body 200 includes a front wall 201 and a rear wall 202 that connect the two ends of two side walls 203 respectively. Each side of the side wall 203 has a second extension surface 2032 that bends and extends towards the front wall 201 and the rear wall 202 respectively. The second extension surface 2032 connects to the corresponding front wall 201 / rear wall 202. The bottom wall 204 of the inner liner body 200 is connected to the first extension surface 2031 via a smooth first arc surface. By designing the second extension surface 2032, the seam position is shifted from the corner between the side wall 203 and the front wall 201 / rear wall 202 to the plane where the front wall 201 or rear wall 202 is located, simplifying the connection between the side wall 203 and the front wall 201 / rear wall 202.

[0151] See Figure 3 and Figure 4 As shown, in one embodiment, after the side plate is stamped and formed by 2034, a recessed surface 2035 is formed at the bottom of the side plate that is recessed into the inner liner. The recessed surface 2035 is used to avoid the slide rail of the dishwasher.

[0152] In the above solution, the inner liner is formed with a recessed surface 2035 for installing the dishwasher slide rail, thereby making full use of the space inside the dishwasher shell and facilitating the expansion of the inner liner.

[0153] Preferably, the recessed surface 2035 includes a recessed surface 2035 that gradually recedes into the inner liner body 200 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 2035, longitudinally crossed 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 body 200 and a second curve 20352 with its center of curvature outside the inner liner. The first curve 20351 and the second curve 20352 transition smoothly. Preferably, the length of the first curve 20351 is equal to the length of the second curve 20352. More preferably, the curvature of the first curve 20351 is equal to the curvature of the second curve 20352. Through this structural design, the tensile strength of the edge of the outwardly convex pressing type, or the two bends of the recessed surface 2035, is the same, the plate is stretched uniformly, and the thickness is uniform, thereby preventing local overstretching from affecting the quality of the inner liner.

[0154] like Figure 5 and Figure 6As shown, in another structure, the recessed surface 2035 is formed by directly stamping the bottom of the side plate into the interior of the inner liner body 200. The recessed surface 2035 includes a horizontally bent surface 20331 formed by bending the bottom wall of the side plate from top to bottom into the interior of 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. This structure is similar to... Figure 4 The structures are different. Figure 4 The concave surface is indirectly formed by the convex stamping die. Because the die is large, it cannot withstand high stamping strength, therefore it lacks a horizontal bending surface (20331). Figure 6 Because the concave surface is directly stamped, the stamping area is small, allowing for the stamping of a concave surface 2035 with a horizontal bending surface 20331 and a vertical bending surface 20332. In this design, the cooperation between the horizontal bending surface 20331 and the vertical bending surface 20332 is more conducive to the installation of the slide rail.

[0155] Preferably, the bottom edge of the side plate is provided with a second extension surface 2031 that bends and extends towards the bottom plate, and the recessed surface 2035 smoothly transitions to the second extension surface 2031. The second extension surface 2031 is connected to the bottom wall 204 of the inner liner body 200.

[0156] Furthermore, the front wall 201 and / or rear wall 202 of the inner liner body 200 are also similar to the two side walls 203, configured as an outward convex structure to expand the inner liner. Their structure can be similar to the two side panels mentioned above, and will not be described in detail here.

[0157] Example 8

[0158] This embodiment will describe the specific structure of the bottom of the inner liner body 200, such as... Figure 17As 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 an inner tank bottom wall 2101 and inner tank bottom sidewalls surrounding the inner tank bottom wall. The inner tank bottom sidewalls are transitionally connected to the inner tank bottom wall 2101, and all inner tank bottom sidewalls are inclined outwards from the inner tank body 200. A certain transition inclination angle is formed between the inner tank bottom sidewall and the normal of the inner tank bottom wall. At least one of the inner tank bottom sidewalls and the inner tank bottom wall 2101 has a smaller transition inclination angle than the other inner tank bottom sidewalls and the inner tank bottom wall 2101. The inner tank bottom is integrally stamped, and a draft angle is provided on the inner tank bottom to facilitate demolding. Meanwhile, considering that a filter screen needs to be installed at the bottom of the inner liner, and that a filter screen with too small an area can easily cause secondary pollution, the transition angle between the inner liner bottom sidewall where the filter screen is installed and the inner liner bottom wall 2101 is smaller than the transition angle between the other inner liner bottom sidewalls and the inner liner bottom wall 2101, so as to leave enough space for the filter screen installation.

[0159] Furthermore, the inner liner body 200 is connected to a door 301. The bottom sidewall of the inner liner includes a front wall 2111 near the door 301. The transition angle between the front wall 2111 and the bottom wall 2101 is smaller than the transition angle between other inner liner sidewalls and the bottom wall 2101. The filter screen is installed between the front wall and the bottom wall near the door. The front wall does not need to avoid the slide rail groove, and a smaller inclination angle can be set to leave enough installation space for installing a filter screen of the largest possible size.

[0160] The inner liner bottom sidewall includes a left inner liner bottom wall 2111 and a right inner liner bottom wall 2113 connected to the two ends of the front inner liner bottom wall, respectively, and a rear inner liner bottom wall 2114 opposite to the front inner liner bottom wall 2111. The transition angle between the front inner liner bottom wall 2111 and the inner liner bottom wall 2101 is smaller than the transition angle between the left inner liner bottom wall 2112 and the inner liner bottom wall 2101, the transition angle between the right inner liner bottom wall 2113 and the inner liner bottom wall 2101, and the transition angle between the rear inner liner bottom wall 2114 and the inner liner bottom wall 2101. 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.

[0161] Specifically, the transition angle between the left wall 2111 and the bottom wall 2101 of the inner liner bottom, the transition tilt angle between the right wall 2113 and the bottom wall 2101 of the inner liner bottom, and the transition tilt angle between the rear wall 2114 and the bottom wall 2101 of the inner liner bottom can be set to the same or different. Considering the regular shape of the inner liner bottom, which is more conducive to the manufacturing of the inner liner bottom stamping mold, this embodiment adopts a method in which the transition angle between the left wall 2111 and the bottom wall 2101 of the inner liner bottom, the transition tilt angle between the right wall 2113 and the bottom wall 2101 of the inner liner bottom, and the transition tilt angle between the rear wall 2114 and the bottom wall 2101 of the inner liner bottom are all set to be the same.

[0162] Furthermore, the bottom wall 2101 of the inner liner has a mounting position 2102 for installing a filter screen on the side near the front wall of the inner liner bottom. A mounting opening 2103 for installing a sprayer is formed at the center of the bottom wall 2101 of the inner liner, and the mounting position 2102 is located between the sprayer mounting opening 2103 and the front wall 2111 of the inner liner bottom. One end of the mounting position 2102 is located near the sprayer mounting opening 2103, and the other end is located near the front wall 2111 of the inner liner bottom, ensuring that the mounting position 2102 for the filter screen is as large as possible, thus maximizing the size of the filter screen and avoiding secondary pollution caused by an undersized filter screen.

[0163] The dishwasher inner tank structure also includes a base support 500 for supporting the inner tank body 200. The base support 500 has a slide rail groove 600 for mounting slide rails. The transition angle between the inner tank bottom sidewall near the slide rail groove 600 and the inner tank bottom wall is greater than the transition angle between other inner tank bottom sidewalls and the inner tank bottom wall. This ensures that the inner tank bottom wall 2101 and the inner tank bottom sidewalls avoid the slide rail groove 600.

[0164] Specifically, the slide rail grooves 600 are respectively set on both sides of the bottom support 500 corresponding to the left wall 2112 and the right wall 2113 of the inner liner bottom.

[0165] Furthermore, a dishwasher water passage is provided on the outside of the inner tank bottom rear wall 2114, and the transition tilt angle between the inner tank bottom rear wall 2114 and the inner tank bottom wall 2101 is used to avoid the dishwasher water passage.

[0166] Furthermore, the inner liner body 200 also includes a side peripheral wall 220 surrounding the bottom of the inner liner, and a connecting portion is provided at the lower edge of the side peripheral wall 220 to connect with the side wall of the bottom of the inner liner. The connecting portion facilitates the connection between the bottom of the inner liner and the side peripheral wall 220 of the inner liner.

[0167] Specifically, the connecting part includes a connecting surface that connects to the corresponding bottom sidewall of the inner liner. The connecting surface is parallel to one side of the corresponding bottom sidewall of the inner liner and is fitted to one side of the edge of the bottom sidewall of the inner liner. The connecting surface and the bottom sidewall of the inner liner are welded together. The parallel arrangement of the connecting surface with one side of the corresponding bottom sidewall of the inner liner facilitates welding.

[0168] 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 inner liner bottom side wall. One end of the inner liner bottom side wall abuts against the limiting surface, and one side of the inner liner bottom side wall is in contact with the connecting surface. The setting of the limiting surface increases the assembly and welding efficiency of the inner liner bottom and the inner liner side peripheral wall 220.

[0169] Example 9

[0170] To facilitate stable placement of the bowl basket, a support structure is provided inside the inner liner body 200. This embodiment will describe the specific location and structure of the support structure. Figure 18 As shown, the inner liner body 200 has a receiving chamber with an opening at the top, in which a bowl basket can be placed. The inner wall of the inner liner body 200 is provided with a support structure for supporting the bowl basket, so that the bowl basket is placed more stably and without shaking inside the inner liner body 200, while avoiding the bowl basket being placed directly on the bottom wall 204 of the inner liner body 200, which would cause the bottom of the bowl basket to wear down the bottom wall 204 of the inner liner body 200 due to shaking.

[0171] The inner liner body 200 includes a bottom wall 204 and side peripheral walls surrounding the bottom wall. The support structure is disposed at the connection between the bottom wall 204 and the side peripheral walls of the inner liner body 200, or the support structure is disposed on the side peripheral walls of the inner liner body 200. In this embodiment, the support structure is disposed at the connection between the bottom wall 204 and the side peripheral walls of the inner liner body 200, so that the support structure and the side peripheral walls 220 together form the support plane of the bowl basket. The side peripheral walls 220 restrict the lateral displacement of the bowl basket, making the bowl basket more stable; at the same time, it makes more effective use of the space of the inner liner body 200.

[0172] Specifically, the bottom wall 204 and the side peripheral wall 220 are connected by a transition rounded corner structure, and the support structure is set on the transition rounded corner structure. The rounded corner structure connecting the bottom wall 204 and the side peripheral wall 220 is more conducive to demolding. During mold making, the mold pulling angle and the forming of the support structure can be made in one piece, which speeds up production efficiency.

[0173] The support structure includes multiple supports 2044 disposed on the inner wall of the inner liner body 200. In order to place the bowl basket stably, the upper surfaces of the multiple supports 2044 are flush to form a support plane for supporting the bowl basket.

[0174] The support body 2044 can be a component independent of the inner liner body 200, and can be installed at the corresponding position on the inner liner body 200 when needed. Alternatively, the support body 2044 can be integrally formed with the inner liner body 200. Considering the connection strength and ease of use between the support body 2044 and the inner liner body 200, in this embodiment, the support body 2044 is integrally formed with the inner liner body 200. The support body 2044 is a protruding structure that protrudes from the inner liner wall towards the inside of the inner liner, and the protruding structure is formed by stamping. The integral formation of the support body with the inner liner body 200 saves the process of installing and connecting the support body 2044. At the same time, compared with the support body 2044 being set separately, the solution of integrally forming the support body with the inner liner body 200 also prevents the support body 2044 from being lost.

[0175] Specifically, the support structure is provided corresponding to the slide rail groove 600.

[0176] Furthermore, mutually cooperating limiting structures are respectively provided on the bottom of the base 500 and the bottom of the inner liner body 200. The limiting structures include a limiting part on the base and a limiting part on the bottom of the inner liner body 200. The limiting part can be located on the bottom wall of the base, on the side of the base's slide rail groove facing the inner liner body 200, or on the side wall of the base. Considering that the limiting part must correspond to the limiting part, and taking into account that the setting of the limiting part does not affect the internal usable space of the inner liner body 200, the inner liner body is located on the bottom wall of the base or on the side of the base's slide rail groove facing the inner liner body 200. In addition, considering that the inner liner body 200 is supported on the slide rail, setting the limiting part on the side of the slide rail groove facing the inner liner body 200 is more conducive to the transmission of supporting force.

[0177] The limiting part can be a support platform or a support column, and the limiting part is a groove structure 2045 that cooperates with the support platform or support column. In this embodiment, the limiting part is a support platform, and the limiting part that cooperates with it is a limiting groove. The support platform and the limiting groove abut against each other to limit the displacement of the inner liner body 200, and at the same time provide support for the inner liner body 200.

[0178] The limiting groove can be provided separately or formed by stamping the inner liner body 200. To ensure better connection strength between the limiting groove and the inner liner body 200, the limiting groove is formed by stamping the inner liner body wall. Considering production efficiency and cost, the side of the protruding structure facing the base 500 is a groove structure 2045 that cooperates with the limiting part of the base. Both the protruding structure and the limiting part are provided corresponding to the slide rail groove. The limiting part, namely the groove structure 2045, at the bottom of the inner liner body 200 is set in a corresponding position to the slide rail groove to facilitate the transmission of the supporting force of the slide rail to the base 500 and the inner liner body 200. At the same time, the protruding structure formed by the inner wall of the inner liner body 200 protruding towards the inside of the inner liner serves as a support structure. The side facing the base 500 is the groove structure 2045 that cooperates with the limiting structure of the base 500. The support structure also serves as the supporting and limiting structure for the bottom of the inner liner and the base 500. It serves multiple purposes and saves the process of manufacturing the second limiting part.

[0179] Furthermore, a first slide rail groove and a second slide rail groove are respectively provided on opposite sides of the base 500. Multiple first protrusion structures are provided on the inner wall of the inner liner body 200 corresponding to the first slide rail groove, and multiple second protrusion structures are provided corresponding to the second slide rail groove. Preferably, the first and second protrusion structures are symmetrically arranged, and it is advisable to provide two of each type of protrusion structure. This ensures the stable placement of the bowl basket while reducing the workload of stamping the protrusion structures.

[0180] Furthermore, the base 500 includes a base bottom wall and a base side wall, and the slide rail groove is disposed at the connection position between the base bottom wall and the base side wall. By placing the slide rail groove on the base instead of the guide rail being located on the base, the guide rail is prevented from protruding beyond the inner liner body 200, thus avoiding the unusable space around the guide rail and increasing the usable space of the inner liner body 200.

[0181] The following examples illustrate the connection structure between the dishwasher inner tank and the outer panel.

[0182] Example 10

[0183] This embodiment will describe the connection structure between the dishwasher inner drum body, the outer side panel 302, and the door 301, such as... Figure 19As shown, the inner liner body 200 has a connecting structure 100 extending outward from the inner liner opening end. The inner liner body 200 includes a first sidewall, on which a first connecting structure 101 for connecting to the door body 301 is provided. Second connecting structures 102 for connecting to the outer side panels 302 are respectively provided on the two side walls adjacent to the first sidewall. The flange structure formed by bending the end of the first sidewall of the inner liner body 200 outward serves as the first connecting structure 101 for connecting to the door body 301. The two side walls adjacent to the first sidewall are respectively provided with second connecting structures 102 for connecting to the outer side panels 302. The flange structure formed by bending the first sidewall of the inner liner body 200, as part of the connecting structure 100, reduces the number of welds between the connecting structure 100 and the inner liner body 200, reduces welding workload, and increases the efficiency of inner liner production.

[0184] Specifically, the end of the first sidewall extends upward to a portion higher than the adjacent sidewalls, and the end of the extension folds outward to the inner liner body 200 to form a horizontal flange structure. The first sidewall is a planar plate structure, and the first connecting structure 101 is formed by folding the end of the planar plate structure. The flange structure avoids the curved surface structure so that the flange structure is formed by folding the planar portion, making the flange structure formation simpler.

[0185] like Figure 20 As shown, the second connecting structure 102 is a connecting flange. Connecting flanges are integrally connected to the opposite side walls of the inner liner body 200. Each side wall adjacent to the first side wall includes a flat portion 205 and a first curved portion 206 that transitions to the first side wall. The connecting flange includes a straight portion 1002 corresponding to the connecting flat portion 205 and a first bent portion 1002 corresponding to the connecting first curved portion 206. The end of the first bent portion 1002 of the connecting flange is spliced ​​to the end of the first connecting structure 101 to form an integral structure, which is formed by welding. Specifically, the straight portion 1001 and the bent portion 1002 are integrally bent, without using welding, snap-fit, or screw connections, increasing the strength of the connecting flange and increasing production efficiency.

[0186] Furthermore, the edge of the connecting flange near the inner liner body 200 extends vertically downward to form a vertical connecting surface, which is fixedly connected to the open end of the inner liner body 200.

[0187] In one embodiment, the inner liner body 200 further includes a second sidewall opposite to the first sidewall. The second sidewall is a planar plate structure with the same shape and size as the first sidewall. The second sidewall is provided with a third connecting structure 103, which is a second flange structure formed by folding the end of the second sidewall. Further, each of the two sidewalls adjacent to the first sidewall also includes a second curved portion 207 that transitions to the second sidewall. The connecting flange also includes a second bent portion 1003 connected to the corresponding second curved portion 207. The connecting flange, the first connecting structure 101, and the third connecting structure 103 are spliced ​​together to form a connecting structure 100 located at the open end of the inner liner body and extending outwards from the inner liner. The connecting structure 100 prevents water in the dishwasher inner liner from splashing out and forming water accumulation between the inner liner and the outer panel, thus affecting the user experience.

[0188] Preferably, the upper surfaces of the connecting flange, the first connecting structure 101, and the third connecting structure 103 are flush with each other and located on the same plane.

[0189] A molding process for a dishwasher inner tank structure, the molding process comprising the following steps:

[0190] (1) The inner liner body 200 is manufactured according to the inner liner size using a stamping, stretching / splicing process;

[0191] (2) The opening end of the inner liner body 200 is bent to form the first connecting structure 101 and the third connecting structure 103 relative to the side wall end, and the connecting flange is integrally formed by stamping and bending.

[0192] (3) Place connecting flanges on the unbent side wall ends of the open end of the inner liner body 200 respectively. The two ends of the connecting flanges are connected to the two ends of the first connecting structure 101 and the third connecting structure 103 respectively. Through the connection process, the open end of the inner liner body has a connecting structure 100 extending to the outside of the inner liner.

[0193] (4) After step (3) is completed, an inner liner is formed. If you need to continue making inner liners, repeat steps (1)-(4).

[0194] Preferably, the connection process in step (3) is welding.

[0195] Example 11

[0196] This embodiment will describe how the connecting structure 100 is specifically connected to the outer side plate, such as... Figure 21-22As shown, the second connecting structure 102 and the outer side plate 302 are respectively provided with limiting structures that cooperate to restrict the movement of the outer side plate 302. The flange structure formed by bending the end of the first side wall of the inner liner body 200 outward is used to connect the first connecting structure 101 of the door body 301, and the two side walls adjacent to the first side wall are respectively provided with second connecting structures 102 for connecting the outer side plate 302. The flange structure formed by bending the first side wall of the inner liner body 200 is part of the connecting structure 100, which reduces the connection weld between the connecting structure 100 and the inner liner body 200, reduces the amount of welding work, and increases the efficiency of producing the inner liner.

[0197] Furthermore, the limiting structure includes a recess 900 / protrusion 800 on the connecting structure 100 and a protrusion 800 / recess 900 on the outer plate 302. The protrusion 800 / recess 900 on the outer plate 302 and the recess 900 / protrusion 800 on the connecting structure 100 engage with each other, restricting the movement of the outer plate 302. Simultaneously, the outer plate 302 and the second connecting structure 102 are connected by an engagement mechanism, serving as a limit for the left, right, and upward movement of the outer plate 302. The connection method is simple and easy to install.

[0198] In another embodiment, the protrusion 800 is a raised structure provided on the outer side plate 302, and the recess 900 is a recess 900 provided on the second connecting structure 102 that can accommodate the protrusion. The raised structure is an upward protrusion at the middle position of the upper end surface of the outer side plate 302, and the recess is a groove that is recessed inward on the lower end surface of the second connecting structure 102 corresponding to the protrusion 800. The protrusion 800 is inserted into the groove of the recess 900.

[0199] As a variation of the above embodiment, the protrusion 800 is a raised structure provided at the lower end of the second connecting structure 102, and the upper end of the outer plate 302 is provided with a recess 900 that can accommodate the protrusion. Preferably, the limiting structure is a protrusion 800 formed by protruding downward at the middle position of the lower end face of the second connecting structure 102, and the recess 900 is a groove on the upper end face of the outer plate 302 that is recessed inward corresponding to the protrusion 800. The protrusion 800 is inserted into the groove of the recess 900.

[0200] In this embodiment, the first connecting structure 101 is an extension portion that extends upward from the end of the first sidewall and is higher than the adjacent sidewalls. The end of the extension portion is folded outward to form a horizontal flange structure. The first sidewall is a planar plate structure. The first connecting structure 101 is formed by folding the end of the planar plate structure portion, which makes the flange structure simpler to form.

[0201] In this embodiment, the second connecting structure 102 is a connecting flange. Connecting flanges are integrally connected to the opposite side walls of the inner liner body 200. The two side walls adjacent to the first side wall each include a flat portion 205 and a first curved portion 206 that transitions to the first side wall. The connecting flange includes a straight portion 1001 corresponding to the connecting flat portion 205 and a first bent portion 1002 corresponding to the connecting first curved portion 206. The end of the first bent portion 1002 of the connecting flange is spliced ​​with the end of the first connecting structure 101 to form an integral structure. The integral structure is formed by welding. Preferably, the straight portion 1001 and the first bent portion 1002 are integrally bent and formed without using welding, snap-fit, screw-fit, or other connection methods, which increases the strength of the connecting flange and increases production efficiency.

[0202] Furthermore, the second connection structure 102 is a connection flange fixedly connected to two side walls adjacent to the first side wall. Each side wall adjacent to the first side wall includes a flat portion 205 and a first curved portion 206 that transitions to the first side wall. The connection flange includes a straight portion 1002 corresponding to the flat portion 205 and a first bent portion 1002 corresponding to the first curved portion 206. The straight portion 1002 is connected to the outer side plate 302, and a limiting structure for restricting the movement of the outer side plate 302 is provided on the straight portion 1002.

[0203] Furthermore, the upper edge of the outer side plate 302 extends inward toward the inner liner body 200 to form a first horizontal surface. A protrusion 900 is formed at the middle of the first horizontal surface. The straight portion 1001 of the connecting flange extends downward toward the edge near the outer side plate 302 to form a vertical connecting surface. The vertical connecting surface is flush with and on the same plane as the outer surface of the outer plate 302. The lower end of the vertical connecting surface extends inward toward the inner liner body 200 to form a second horizontal surface. A groove 800 is formed at the middle of the second horizontal surface, which fits tightly against the first and second horizontal surfaces, and the protrusion 800 is engaged within the groove.

[0204] Preferably, the protrusion 800 is a through protrusion located at the middle position of the first horizontal plane, and the recess 900 is a through groove located at the middle position of the second horizontal plane.

[0205] In one embodiment, the inner liner body 200 further includes a second sidewall opposite to the first sidewall. The second sidewall is a planar plate structure with the same shape and size as the first sidewall. The second sidewall is provided with a third connecting structure 103, which is a second flange structure formed by folding the end of the second sidewall. Further, each of the two sidewalls adjacent to the first sidewall also includes a second curved surface 207 that transitions to the second sidewall. The connecting flange also includes a second bent portion 1003 connected to the corresponding second curved surface 207. The connecting flange, the first connecting structure 101, and the third connecting structure 103 are spliced ​​together to form a connecting structure 100 located at the open end of the inner liner body 200 and extending outward from the inner liner body 200.

[0206] Preferably, the upper surfaces of the first connecting structure 102, the first connecting structure 101, and the third connecting structure 103 are flush with each other and located on the same plane.

[0207] In another embodiment, the difference between this embodiment and the above embodiment is that the second connecting structure 102 is a flanged structure integrally formed with the inner liner body 200. Specifically, the flanged structure is formed by folding the upper edges of the two side walls adjacent to the first connecting structure 101 outwards towards the inner liner body 200. The flanged structure includes a first horizontal flange 700, a longitudinal flange 701, and a second horizontal flange 702. The first horizontal flange 700 is formed by folding one side edge of the inner liner body 200 horizontally outwards towards the inner liner. The side edge of the first horizontal flange 700 extends vertically downwards to form the longitudinal flange 701. The lower edge of the longitudinal flange 701 extends inwards towards the inner liner body 200 to form the second horizontal flange 702. The second horizontal flange 702 is provided with a limiting structure to restrict the movement of the outer side plate 302.

[0208] Furthermore, the upper edge of the outer side plate 302 extends into the inner side of the inner liner body 200 to form a first horizontal surface. The middle position of the first horizontal surface protrudes upward to form a protrusion 800. The middle position of the second horizontal flange 702 is recessed inward to form a groove that cooperates with the protrusion 800. The first horizontal surface and the second horizontal flange 702 fit tightly together, and the protrusion 800 is engaged in the groove.

[0209] Specifically, the protrusion 800 is a through protrusion located at the middle position of the first horizontal plane, and the recess 900 is a through groove located at the middle position of the second horizontal plane.

[0210] Example 12

[0211] This embodiment will describe how the inner liner body is connected to the door 301, such as... Figure 23-30As shown, the dishwasher includes an inner liner body 200 and a door 301 disposed on the side of the inner liner body. The inner liner body 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 301, and at the same time limits the connecting structure 100, making the overall assembly effect more compact and firm, thus improving the aesthetics and safety of the dishwasher.

[0212] 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. The ends of the plane are then folded towards the center of the door body 301 to form an inner wall surface. The assembly structure consists of protruding ribs on the inner wall surface. The door body 301 is formed by bending a single sheet of material. The manufacturing process is simple, the door body 301 has a concise structure, an attractive appearance, and improved manufacturing efficiency.

[0213] 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, and adjacent plates are integrally connected. Raised ribs are located on the inner wall surface connected to the upper edge of the outer wall surface of the door body 301 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 of the door body 301 are straight, elongated strips extending along the width direction of the door body 301, while the raised ribs on the inner wall surface connected to the side edges of the outer wall surface are generally n-shaped. This shape facilitates the limiting and locking of the outer edge of the connecting plate. The middle part of the raised rib is a straight, elongated strip extending along the height direction of the door body 301. Both ends of the straight, elongated raised rib are bent inwards towards the door body 301, and the upper end, after bending, is flush with the straight, elongated raised rib extending along the width direction of the door body 301.

[0214] 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 body 301, and the pressed ribs 3012 are located on the inner wall surface connected to the side edges of both sides of the door body 301. The rolled ribs 3011 are straight strips extending along the width direction of the door body 301, and the pressed ribs 3012 are n-shaped. This shape facilitates the limiting and locking of the outer edge of the connecting plate. The middle part of the rib is a straight strip extending 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, and the upper end is flush with the rolled ribs 3011 extending along the width direction of the door body 301 after bending.

[0215] 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 body 301. The end of the rolled edge structure is flush with the wall surface before folding. The straight part 1001 of the connecting structure on the top surface of the straight side wall of the inner liner body 200 is also present. The straight part 1001 of the connecting structure has a door connecting plate 10011 that engages with the rolled rib 3011. 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 is in contact with the wall surface of the rolled rib 3011 away from the inner liner body 200. The bottom surface of the rolled structure at the lower end of the rolled rib 3011 is in contact with the plane connecting the lower end of the door connecting structure 10021. The lower end of the folding rib 3011 is designed to prevent the edge of the inner wall panel of the door 301 from directly contacting the door connecting structure 10021. This prevents noise during the operation of the dishwasher and avoids scratches caused by friction during the pushing and pulling of the dishwasher. Additionally, a gasket can be placed between the folding structure and the door connecting structure 10021 to reduce friction and noise.

[0216] The pressed rib 3012 is a pressed structure that protrudes towards the inner liner body 200. The pressed rib 3012 has a first bending structure 30121 and a second bending structure 30122. The first bending structure 30121 is located on the upper part of the inner wall surface, and the end face of the first bending structure 30121 is integrally connected with the end face of the rolled rib 3011.

[0217] A first bending portion 1002 of the connecting structure is connected to the top surface of the rounded transition sidewalls on both sides of the straight sidewall of the inner tank body 200. The first bending portion 1002 of the connecting structure has a connecting plate 10021. The edge of the door connecting plate 10021 engages with the edge of the first bending portion 30121, and the side surface of the door connecting plate 10021 away from the inner tank body 200 is in contact with the side surface of the inner wall of the door body close to the inner tank body 200. The door connecting structure has through holes, and the inner wall of the door body also has through holes, with the two through holes corresponding one-to-one. A fastening device connects the door connecting structure 10021 to the door body 301. The pressed ribs prevent the sharp edges of the connecting structure from directly contacting the inner wall of the door body, while also limiting the position of the connecting structure, facilitating assembly and installation. Furthermore, the pressed ribs prevent the edges of the connecting structure from being exposed in the line of sight, enhancing the aesthetics of the dishwasher.

[0218] The invention also includes an outer side plate 302 located on the side of the inner liner body 200, and an outer side plate connecting plate 3021 is provided on the outer side plate 302. The outer edge of the outer side plate connecting plate 3021 engages with the elongated edge of the middle part of the pressed rib. The outer side plate connecting plate 3021 is a rectangular strip, and the lower edge of the rectangular strip engages with the edge of the second bending structure 30122. The outer side plate connecting plate 3021 is provided with through holes, and there are also through holes on the inner wall of the door. The two through holes correspond one-to-one. The outer side plate connecting plate 3021 is connected to the door body 301 by a fastening device. The setting of the pressed rib can prevent the sharp edge of the connecting plate from directly contacting the inner wall of the door, and at the same time limit the connection structure, which facilitates assembly and installation. In addition, the pressed rib can block the edges of the connection structure from being exposed in the line of sight, enhancing the aesthetics of the dishwasher.

[0219] In this embodiment, when the outer wall of the door body 301 is bent to form the thickness of the door body 301, gaps are formed at the four corners of the door body by adjacent bending plates. In order to improve the stability and aesthetics of the door body, corner pieces 3013 are provided at the gaps. Corner pieces 3013 include corner piece base 30131 and corner piece plug 30132. During assembly, the corner piece base 30131 is built into the door body, and the part of the corner piece base 30131 that mates with the corner piece plug 30132 is placed at the gap. Then, the corner piece plug 30132 is inserted into the corner piece base 30131. After the corner pieces 3013 are installed, the subsequent installation between the door body 301 and the connecting structure is carried out.

[0220] Example 13

[0221] This embodiment is a further limitation of the above embodiment twelve, such as... Figure 23-30 As shown, the inner liner body 200 includes sidewalls with a flat top, and the sidewalls are connected by rounded corner transition sidewalls. The connection structure 100 includes a flat connection structure 1001 connected to the top of the sidewall and a rounded corner connection structure connected to the rounded corner transition sidewall.

[0222] The straight connecting structure 1001 is elongated, with its bottom surface being a straight surface that matches the shape of 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 connecting structure 1001 is integrally formed with the side wall, which greatly reduces the weld length during the dishwasher manufacturing process and improves product production efficiency.

[0223] The rounded corner connection structure is angular, with its bottom surface being an arc surface that matches the rounded corner transition sidewall shape. The end faces of the rounded corner connection structure on both sides match the end faces of the adjacent straight connection structure 1001. The end faces of the rounded corner connection structure are spliced ​​with the adjacent straight connection structure 1001, and the top surface of the rounded corner transition sidewall between the bottom surface and the sidewall is spliced, folding outwards towards the inner liner body 200 after splicing. Welds only appear on the end faces where adjacent straight connection structures are spliced ​​and on the top surface where they are spliced ​​with the rounded corner transition sidewall, significantly reducing weld length and improving the overall aesthetics of the dishwasher.

[0224] It also includes a door body 301, and an inner liner body 200 including a front wall 201 near the door body 301. A connecting plate 10011 is provided on the straight connecting structure 1001 to be spliced ​​with the door body 301. The straight connecting structure 1001 is located on the top surface of the front wall 201 and is integrally formed with the front wall 201. The front wall 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 folding outwards towards the inner liner. The outer edge of the folding structure is folded upwards to form a long strip-shaped plate structure.

[0225] Two outer side panels 302 are located on both sides of the inner liner body 200, parallel to the dishwasher's stretching direction. The inner liner body 200 also includes two side walls 203 parallel to the dishwasher's stretching direction. A straight connecting structure 1001 has an overlapping plate 10012 that splices with the outer side panels 302. The straight connecting structure 1001 is located on the top surface of the side wall 203 and is integrally formed with it. The straight connecting structure 1001 connected to the side wall 203 folds outwards towards the inner liner and then folds downwards to form a plane perpendicular to the door body 301 and parallel to the side wall 203. The bottom surface of the plane folds towards the side wall 203 to form a horizontal overlapping plate 10012 perpendicular to the side wall 203. The side wall 203 of the overlapping plate 10012 of the straight connecting structure connects to the outer side panel 302. This structure serves to connect the inner tank body 200 with the outer side panel 302. At the same time, the straight connecting structure 1001 is made of stainless steel, which greatly enhances the overall aesthetics of the dishwasher. In addition, the stainless steel material is easy to clean, resulting in a good user experience.

[0226] The inner liner body 200 also includes rounded transition sidewalls located between the front wall 201 and the side wall 203. The top surface of the rounded transition sidewall is arc-shaped, and the rounded corner connecting structure has a downward arc-shaped flange, the bottom surface of which connects to the top surface of the rounded transition sidewall. The rounded corner connecting structure also has a door connecting structure 10021 that splices with the door body 301 and an overlapping plate 10022 that splices with the side wall. The rounded corner connecting structure is spliced ​​with the rounded transition sidewall, the adjacent straight connecting structure, the door body 301, and the outer side panel 302.

[0227] The rounded corner connection structure connected to the top surface of the rounded corner transition sidewall is angular, with 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 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.

[0228] The first transition connecting edge 10023 is perpendicular to the door body, and the second transition connecting edge 10024 is parallel to the door body. The door body connecting structure 10021 is formed by outwardly turning the end where the first transition connecting edge 10023 and the second transition connecting edge 10024 meet. Alternatively, in another embodiment of this invention, the door body connecting structure 10021 is formed by extending outward from the end where the second transition connecting edge 10024 meets the first transition connecting edge 10023.

[0229] 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 is folded downwards, and the bottom surface is connected to the top surface of the rounded corner transition sidewall. The first outer edge 100231 is folded downwards to form a plane perpendicular to the door body 301 and parallel to the sidewall 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.

[0230] The bottom of the first outer edge 100231, which folds downwards, folds towards the side wall 203 to form a horizontal overlapping plate 10022 perpendicular to the side wall 203. The overlapping plate 10022, with its rounded corners, connects to the outer side wall 302 via a rounded corner connection structure. It connects to the door 301 via a rounded corner transition side wall through a door connection structure 10021, and to adjacent straight connection structures 1001 via the first inner edge 100232 and the second inner edge 100242, respectively. This structure serves to connect the inner tank body 200 to the outer side wall 302 and the door 301. Furthermore, the use of stainless steel in the rounded corner connection structure greatly enhances the overall aesthetics of the dishwasher. The stainless steel material is also easy to clean, providing a better user experience.

[0231] The inner tank body 200 also includes a rear wall 202 opposite to the front wall 201. The straight connecting structure 1001 is disposed on the top surface of the rear wall 202. The straight connecting structure 1001 on the rear wall 202 is integrally formed with the rear wall 202, folding outwards towards the inner tank and then vertically folding downwards to form a planar structure parallel to the rear wall 202. This structure can connect two connected rounded corner connecting structures, making the connecting structure 100 on the inner tank opening a complete structure, thus improving the aesthetics of the dishwasher.

[0232] Combination Figure 2 , Figure 10 , Figure 13 and Figure 14 The inner liner body 200 also includes rounded transition sidewalls located between the rear wall 202 and the side wall 203 respectively. The rounded connection structure is provided with an overlap plate 10022 that splices with the outer side plate 302. The rounded connection structure is spliced ​​with the rounded transition sidewall, the adjacent straight connection structure 1001 and the outer side plate 302.

[0233] The rounded corner connection structure connected to the top surface of the rounded corner transition sidewall is angular, similar to the rounded corner connection structure 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 structure on both sides of the straight connection structure 1001 on the top surface of the rear wall 202 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 1001 respectively. The first transition connection edge 10023 is parallel to the rear plate 202, and the second transition connection edge 10024 is perpendicular to the rear wall 202. 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 of the first inner edge 100232 and the second inner edge 100242 is folded downwards, and the bottom surface is connected to the top surface of the rounded corner transition sidewall. The first outer edge 100231 folds downward to form a plane parallel to the rear wall 202, and the second outer edge 100241 folds downward to form a plane perpendicular to the rear wall 202. The bottom of the plane folds towards the side wall 203 to form a horizontal overlapping plate 10022 perpendicular to the side wall 203. The overlapping plate 10022 of the rounded corner connection structure connects the side wall and the outer wall 302 through rounded corner transitions. The first inner edge 100232 and the second inner edge 100242 are respectively connected to the adjacent straight connecting structure 1001. This structure not only connects the inner tank body 200 and the outer panel 302, but also uses stainless steel for the rounded corner connection structure, which greatly improves the overall aesthetics of the dishwasher. In addition, stainless steel is easy to clean, providing a good user experience.

[0234] The straight connecting structure 1001 and the rounded corner connecting structure, which connect to the front wall 201, side wall 203, and the top surface of the rounded transition side walls on both sides of the inner liner body 200, have overlapping plates 10012 and 10022 on them, each with a groove for splicing with the outer side plate 302. The grooves are recessed towards the opening of the inner liner. The top surface of the outer side plate 302 has a protruding structure that mates with 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, and the protruding structure is embedded inside the groove. In this embodiment, the mating of the groove and the protruding structure is as follows: Figure 22 As shown, this structure greatly reduces the connection gap between the outer panel 302 and the overlapping plate, preventing the outer panel 302 from shifting and generating noise during the operation of the dishwasher.

[0235] The following examples illustrate how the inner drum of a dishwasher is connected to the base, how the base is connected to the outer panel, and the specific structure of the base.

[0236] Example 14

[0237] This embodiment will describe how the inner liner body is connected to the base, such as... Figure 31 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 connecting plate 2001 disposed at the bottom of the inner tub body 200 and extending outwards from the inner tub body 200. The connecting plate 2001 is fixedly connected to the base 500. The connecting plates 2001 can be spaced apart, ensuring a fixed connection between the inner tub body 200 and the base while saving production materials.

[0238] In this embodiment, a connecting plate 2001 is installed all around the bottom of the inner liner. The connecting plate 2001 can serve as a fixing structure to fix the inner liner body 200 and the base 500 together, and it can also serve as a sealing structure to seal the space between the inner liner body 200 and the base 500, preventing water from leaking out of the inner liner body 200 from overflowing from the base 500, thus providing the user with a better user experience.

[0239] Specifically, the inner liner body 200 is composed of annular side plates and a bottom plate joined together. The connecting plate 2001 extends from the outer wall of the annular side plate towards the outer side of the inner liner body 200, and / or extends from the peripheral wall of the bottom plate towards the outer side of the inner liner body 200, and / or extends from the joint between the annular side plate and the bottom plate towards the outer side of the inner liner body 200. In this embodiment, the connecting plate 2001 extends from the joint between the annular side plate and the bottom plate towards the outer side of the inner liner body 200 to cover the joint seam. At the same time, both the annular side plate and the bottom plate are connected to the base support, increasing the connection strength between the entire inner liner body 200 and the base support.

[0240] Furthermore, the annular side plate and the bottom plate are connected by a splicing structure. This splicing structure consists of a first connecting surface and a second connecting surface formed by bending the edges of the side plate and the bottom plate outwards towards the inner liner, respectively, and are then joined together. This splicing structure serves as a connecting plate 2001, which is fixedly connected to the side wall of the base. By using the splicing structure as a connecting plate 2001, the process of remanufacturing the connecting plate 2001 and connecting it to the inner liner body 200 is eliminated, increasing the production efficiency of the dishwasher's inner liner structure.

[0241] It also includes a connector that securely connects the inner liner body 200 and the base 500. The connecting plate has mounting holes, and the connector passes through these holes to securely connect with the base 500, fixing the inner liner body 200 to the base 500. Specifically, the connector is a connecting bolt, and the base 500 has threaded holes for assembling with the connecting bolt. Bolted connections provide a more stable and simpler connection method, avoiding the hazards associated with welding during welding operations.

[0242] The inner wall of the base 500 is provided with a connecting boss 5033 that mates with the connecting plate 2001. The connecting boss 5033 and the connecting plate 2001 are fastened together by a connector. The connecting boss 5033 facilitates the connection and fixation between the connecting plate 2001 and the base 500. When the connecting plate 2001 contacts the connecting boss, it indicates that the installation position of the inner liner body 200 and the base 500 has been reached, increasing the assembly efficiency of the inner liner body 200 and the base 500.

[0243] Furthermore, the base 500 includes a base side wall and a base bottom wall, which together form a cavity for accommodating the bottom of the inner liner body. The connecting boss 5033 can be provided on the base side wall or the base bottom wall, and is set at a height higher than the bottom plate of the inner liner body 200. This avoids the vibration generated by the inner liner body 200 being directly transmitted to the base, thus preventing greater vibration noise.

[0244] In this embodiment, the connecting boss 5033 is disposed on the side wall of the base, and the connecting boss 5033 is disposed corresponding to the mounting hole on the connecting plate 2001. The connecting boss 5033 can be spaced apart or disposed as a whole along the circumference of the side wall of the base. Specifically, the connecting boss 5033 is disposed as a whole along the circumference of the side wall of the base. This prevents washing water from overflowing from the inner tank body 200 during operation, as overflowing water from the base would affect the user experience.

[0245] Considering that the connecting boss 5033 has better connection strength and fewer processing steps with the bottom support sidewall, the connecting boss 5033 is integrally formed by bending and extending the bottom support sidewall into the bottom support.

[0246] Furthermore, a waterproof structure 501 is also provided on the side wall of the base support. The waterproof structure 501 is formed by extending upward from the free end of the side wall of the base support. The waterproof structure 501 is set higher than the connecting boss 5033 to further prevent water leakage from the inner liner.

[0247] Example 15

[0248] This embodiment describes the specific structure of the base. For example... Figure 32As shown, a waterproof structure 501 is provided at the connection point between the base 500 and the inner tub body 200 to prevent water leakage from the inner tub. When water overflows from the inner tub body 200 during dishwasher operation, the waterproof structure 501 allows the overflowing water to flow directly back into the cavity of the base 500, effectively preventing the overflowing water from splashing onto the outside of the dishwasher, wetting the dishwasher drawer, and avoiding water spillage during the user's operation, thus preventing contamination of the user's home environment and clothing.

[0249] The base tray 500 includes a base tray bottom wall 502 and an upwardly extending base tray side wall 503 connected to the base tray bottom wall 502. The base tray bottom wall 502 and the base tray side wall 503 form an upward-opening receiving cavity. The inner liner body 200 is placed in the receiving cavity of the base tray 500. A base tray connecting structure 504 for connecting the inner liner body 500 is provided on the base tray side wall 503. A waterproof structure 501 is arranged around the base tray connecting structure 504 to form circumferential waterproofing to the bottom of the inner liner body 200. This allows overflow water to flow directly back into the cavity of the base tray 500, effectively preventing overflow water from splashing onto the outside of the dishwasher, wetting the dishwasher drawer, and avoiding overflow water being carried out during the user's operation, thus preventing pollution of the user's home environment and clothes.

[0250] The base support connecting structure 504 is located on the top of the base support side wall 503. The waterproof structure 501 is a water-blocking rib located on the base support side wall 503, with its bottom surrounded by the base support connecting structure 504. The water-blocking rib is located on the outer edge of the top of the base support side wall 503 and extends circumferentially around the top of the base support side wall 503. The base support connecting structure 504 is located on the inner edge of the top of the base support side wall 503 and is spaced circumferentially around the top of the side wall. There is a gap between the waterproof structure and the base support connecting structure, which allows water to flow through the gap between the two and collect back into the base support 500 receiving cavity.

[0251] The base connection structure 504 is a guide rib 504 set on the top of the base side wall 503. The side surface of the guide rib near the center of the base 500 is opposite to or attached to the outer wall surface of the inner tank body 200. There are multiple guide ribs, which are circumferentially spaced around the top of the base side wall 503. When the inner tank body 200 is placed, it provides installation guidance for the inner tank body 200, which is beneficial to improving the assembly efficiency of the dishwasher. At the same time, the spaced guide ribs facilitate the return of the collected water flow from the gaps between the guide ribs to the receiving cavity of the base 500.

[0252] The top of the bottom support sidewall 503 extends outward from the bottom support 500 to form an annular plane surrounding the interior of the bottom support 500. The water-blocking rib is located on the outer edge of the annular plane, and the bottom support connecting structure 504 is located on the inner edge of the annular plane. The annular plane is formed by bending and extending the top of the bottom support sidewall 503 outward from the bottom support 500, and the water-blocking rib is located on the outer edge of the annular plane.

[0253] Example 16

[0254] This embodiment describes how the base 500 is connected to the outer panel. For example... Figure 33 As shown, the system includes an inner tub body 200, a base 500, and an outer panel. The inner tub body 200 is mounted on the base 500, and the outer panel is located on the outside of the inner tub body 200. The base 500 is provided with a connecting structure for connecting the outer panel. Connecting the outer panel via this connecting structure, rather than having the inner tub body 200 directly rest on the outer frame, facilitates transportation and makes assembly of the inner tub body 200 and the outer panel easier. Recalling Embodiment Ten, where the upper end of the outer panel is fixedly connected to the connecting structure located at the open end of the inner tub body 200, this embodiment, to ensure a more stable connection between the outer panel and the inner tub body 200 on the base 500, provides a connecting structure on the base 500 that connects to the lower end of the outer panel. This prevents vibration and noise during dishwasher operation due to the outer panel being fixed at only one end, thus avoiding negative impacts on the user experience.

[0255] Furthermore, the connecting structure includes a connecting portion 5041 and an assembly portion 5042. The connecting portion 5041 extends from the outer wall of the base support towards the outside of the base support 500, and the assembly portion 5042 is disposed on the connecting portion 5041 for assembly connection with the lower end of the outer plate. The connecting structure can be fixedly connected to the outer wall of the base support 500 or integrally formed with the outer wall of the base support 500. This embodiment adopts the scheme of integrally forming the connecting structure with the outer wall of the base support, which saves the manufacturing process of the connecting structure and the connection process between the connecting structure and the outer wall of the base support, increases production efficiency, and strengthens the connection strength between the connecting structure and the outer wall of the base support.

[0256] The outer panel includes a door body 301, and the base support 500 includes a base support front wall near the door body 301 and two base support side walls connected to the two ends of the base support front wall respectively. The connecting structure is respectively set on the two opposite base support side walls for connecting the bottom ends of the two outer outer panels 302, so that the outer outer panels 302 are firmly fixed and vibration is avoided to prevent noise.

[0257] Specifically, the sidewall of the base extends horizontally outward to form a connecting portion 5041, and the assembly portions 5042 extend horizontally along the connecting portion 5041, or are spaced apart. In this embodiment, the assembly portions 5042 extend horizontally along the connecting portion 5041, increasing the connection strength between the outer panel and the base.

[0258] In another embodiment, the sidewall of the base extends at certain intervals in the length direction to form a plurality of connecting parts 5041, and each connecting part 5041 is provided with an assembly part 5042, thereby realizing the connection function between the outer panel and the base 500 while reducing production costs.

[0259] Furthermore, the assembly part 5042 is a plug-in protrusion provided on the connecting part 5041. The bottom of the outer plate is provided with a plug-in groove for cooperating with the plug-in protrusion. The plug-in engagement restricts the displacement of the outer plate in the left, right and downward directions. In the recap of embodiment ten, the connecting structure provided at the opening end of the inner liner body 200 restricts the upward displacement of the outer wall. The two cooperate with each other to firmly fix the outer plate to the outside of the inner liner body 200.

[0260] Specifically, the distance between the side of the inserting rib near the bottom support sidewall and the outer surface of the bottom support sidewall is greater than or equal to the wall thickness of the inserting groove. In this invention, the distance between the side of the inserting rib near the bottom support sidewall and the outer surface of the bottom support sidewall is equal to the wall thickness of the inserting groove. The bottom support sidewall can serve as a positioning structure. When the inserting groove at the bottom of the outer plate is inserted into the assembly part 5042, it can first be placed against the bottom support sidewall and then pushed downwards along the bottom support sidewall to successfully engage the inserting groove and the inserting rib. This reduces the assembly difficulty for workers and increases assembly efficiency.

[0261] Furthermore, the outer panel includes an outer side panel 302, the upper end of which is fixedly connected to the open end of the inner liner body 200, and the lower end is fixedly connected to the connection structure of the base 500.

[0262] The connecting structure is located on the outer side wall of the base 500 near the slide rail groove 600. Specifically, the base 500's side wall outside the slide rail groove 600 extends downwards to form a connecting portion 5041, which extends outwards from the base 500 and extends towards the outside of the base 500. The base side wall also serves to conceal the slide rail groove 600, preventing it from being exposed and affecting the aesthetics of the dishwasher's inner tank structure.

[0263] Example 17

[0264] This embodiment describes the cooperation between the inner liner body 200 and the support structure 506 of the base 500, such as... Figures 35-36 As shown, the support structure is provided on the side of the slide rail groove 600 facing the inner liner body 200, or on the bottom support side wall 503, or at the junction of the bottom support side wall and the slide rail groove.

[0265] Specifically, the base 500 includes a base wall 502 and a base side wall 503. The base side wall 503 is circumferentially arranged around the base wall 502 to form a receiving space that can accommodate the bottom of the inner tub body 200. The lower part of the two outer side walls of the base 500, which are parallel to the stretching direction of the dishwasher, is provided with a slide rail groove 600 that is recessed into the inner tub body 200. The inner wall of the base side wall 503 is provided with a support structure 506 that cooperates with the bottom of the inner tub body 200. The support structure 506 not only provides support for the inner tub body 200, but also plays a role in transmitting force between the base 500 and the inner tub body 200 when the dishwasher is stretched.

[0266] 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, multiple support platforms are provided, and the support platforms are evenly distributed circumferentially on the inner wall of the base sidewall 503. Each support platform includes a support platform planar portion 5061 integrally formed with the base sidewall 503. The bottom wall of the inner liner body 200 is located on the support platform planar portion 5061, 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 planar, 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.

[0267] The support platform plane 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.

[0268] Specifically, the bottom support sidewall 503 of this embodiment includes a vertical plate 5031 and an inclined plate 5032 extending from the upper end of the vertical plate 5031 towards the outside of the inner liner. The inclined plate 5032 is circumferentially arranged around the upper edge of the vertical plate 5031, forming a receiving space with an outwardly radiating upper opening. The bottom of the inner liner body 200 rests within 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 fixedly arranged 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 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 bending or deformation when supporting the inner liner body 200.

[0269] 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 that mates with the support structure 506 is provided at the junction of the bottom wall 204 and the side peripheral wall 220 of the inner liner body 200, increasing the stability between the inner liner body 200 and the base 500. The positioning structure is the groove structure 2045 in Embodiment Nine. Through the positioning structure, 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, thereby significantly increasing the support stability of the support structure 506.

[0270] Specifically, the positioning structure is a recessed groove structure 2045 formed at the junction of the bottom wall 204 and the peripheral wall of the inner liner body 200, which is recessed into the inner liner body 200. The groove structure 2045 matches the shape and size of the support structure 506. In this embodiment, the positioning structure 700 is a stamped structure formed directly by a stamping process, which is simple to manufacture. At the same time, the formed stamped structure can not only cooperate with the support structure 506 to prevent the bottom support 500 from separating from the inner liner body 200, but also serve to support the shelves, dish racks, etc. inside the dishwasher.

[0271] In another embodiment, a support platform is disposed on the side of the slide rail groove 600 facing the inner liner body 200, and a positioning structure, i.e., a groove structure 2045, disposed on the inner liner body 200 is correspondingly disposed on the support platform. The inner liner body 200 is supported on the slide rail via the slide rail groove 600, and the support platform is used to limit and support the inner liner body. The support platform being disposed on the slide rail groove 600 is beneficial for the transmission of force.

[0272] To reduce the transmission of vibration and noise during the sliding process of the inner tub body 200, the support platform also includes a plastic shock-absorbing pad attached to its outer surface. When the vibration of the inner tub body 200 is transmitted to the support platform, the vibration is buffered and absorbed by the support platform due to its elasticity, thereby effectively blocking the transmission of vibration and reducing the generation of noise, which helps to reduce the noise of the dishwasher.

[0273] 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. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
