[0061] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0062] like Figure 1 As shown, the present invention provides a dishwasher liner structure, which is mainly used in drawer-type dishwashers. Compared with front-opening dishwashers, users need to bend down or even squat to open the door body completely, which is more tiring for users to use. When the front-opening dishwasher is put into the dishes to be washed, the residual soup of the dishes to be washed is easy to spill outside the dishwasher due to the lack of surrounding, which will undoubtedly cause a poor user experience. The drawer-type dishwasher adopts a pull-out door opening design, which can open the dishwasher without bending down or squatting, and is more ergonomically designed. When the dishes to be washed are put in, there is no need to worry about the problem of residual soup spilling out of the dishes to be washed due to the surrounding design. The dishwasher liner structure includes an inner liner body 200 and an outer plate arranged on the outer side of the inner liner body. A bottom bracket 500 is installed at the bottom of the inner liner body 200, and a bottom cover 400 is also arranged between the bottom of the inner liner body 200 and the bottom bracket 500. The structure and connection relationship of each part of the dishwasher liner structure in the present invention are introduced through embodiments.

[0063] The liner body 200 of the present invention can be formed in one piece, or can be formed by splicing a plurality of parts.

[0064] The present invention provides several different methods for manufacturing the inner tank body 200. The following describes how the inner tank body 200 of a dishwasher is manufactured through the following embodiments.

[0065] Embodiment 1

[0066] In this embodiment, the liner body 200 is made by splicing three parts, and the specific splicing method is as follows.

[0067] like Figure 2 As shown, the liner body 200 is formed by splicing at least two parts, and the splicing positions between the parts are located on a plane, which greatly reduces the difficulty of the welding process during the assembly process and improves the assembly efficiency.

[0068] The dishwasher inner tank body 200 in the present invention is composed of three parts, 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 pulling direction of the dishwasher. The splicing position of the second part / third part and the first part is located on a plane.

[0069] The first component includes a bottom wall 204 of the inner container body, and a front wall 201 and a rear wall 202 connected to the bottom wall 204 and perpendicular to the pulling direction of the dishwasher.

[0070] The second component / third component includes a side wall 203 parallel to the pulling direction of the dishwasher, and the second component / third component also includes an extension portion connected to the side wall 203 and bent toward the opposite side wall, the extension portion is connected to the first component, and the extension portion and the side wall 203 are smoothly connected through a rounded structure. The setting of the extension portion avoids the splicing position of the second component / third component and the first component on a curved surface and makes the splicing position on a plane, thereby reducing the difficulty of welding.

[0071] The second component / third component is integrally formed by stamping, and the extension portion 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 structure, and the second extension surface 2032 extends straight toward 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.

[0072] like Figure 3As shown, it is a front view of the inner tank body 200 of the present invention. The dishwasher is pulled out by a slide rail. The side wall 203 of the second component / third component includes a recessed surface 2033. The recessed surface 2033 is a receiving portion recessed toward the center of the inner tank. The receiving portion can be installed with a slide rail to facilitate stretching the dishwasher and taking and placing tableware in the dishwasher.

[0073] Embodiment 2

[0074] Different from the first embodiment, the inner liner body 200 in this embodiment is formed by bending the inner liner side wall 220 of a plate, and the side wall 220 is spliced ​​with the inner liner bottom wall, and the specific splicing method is as follows.

[0075] like Fig. 9 and Fig.10 As shown, the inner tank body 200 includes an inner tank bottom wall 204 and an inner tank side peripheral wall 220, wherein the inner tank bottom wall 204 and the inner tank side peripheral wall 220 form an inner tank body 200 with an opening facing upward, wherein the inner tank peripheral wall 220 is a plate member that is bent and rolled into a ring shape, wherein one end of the plate member has a splicing portion 221, and the other end is overlapped on the splicing portion 221, and the splicing positions 222 at both ends are located on a plane. The influence of the dimensional error on the assembly structure is eliminated, and the splicing parts with the final size determined are welded conveniently, the weld is regular, the welding plane processing process is simple, and the manufacturing efficiency of the dishwasher is improved.

[0076] like Fig.10 As shown, the splicing portion 221 is a bending structure formed by bending one end of a plate, and the end of the bending structure remains parallel to the other end 2211 of the plate. The bending structure includes a first bending structure 2212 and a first extension structure 2213. The first bending structure 2212 is formed by bending one end of the plate toward the outside of the inner liner, and the first extension structure 2213 is formed by bending and extending the end of the first bending structure 2212, and remains parallel to the other end 2211 of the plate.

[0077] like Fig.10 As shown, the side surface of the first extension structure 2213 close to the inner center of the inner container is fitted with the side surface of the other end 2211 of the plate away from the inner center of the inner container and connected as one body.

[0078] The inner wall surface of one end of the plate before being bent is flush with the inner wall surface of the other end 2211 of the plate.

[0079] The vertical distance that the first bending structure 2212 bends toward the outside of the inner container is equal to the thickness of the plate, and 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 end surface of the other end 2211 of the plate is in contact with the bending surface of the first bending structure 2212 .

[0081] There is a gap between the end surface of the other end 2211 of the plate and the bending surface of the first bending structure 2212 .

[0082] The gap between the end surface of the other end 2211 of the plate and the bending surface of the first bending structure 2212 is filled with welding material, a sealing strip or a retaining rib.

[0083] like Fig. 9 As shown, the inner liner side wall 220 includes four straight side walls, with rounded transition side walls between the straight side walls, and the splicing position is located on the straight side walls. The straight side walls 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.

[0084] like Fig. 9 As shown, the liner bottom wall 204 includes an liner bottom wall and an liner bottom side wall 211 formed by folding the edge of the liner bottom wall upward. The liner bottom wall 204 is an upwardly open small accommodating cavity structure, and the bottom surface of the liner side peripheral wall 220 is spliced ​​with the top surface of the liner bottom wall 204.

[0085] In this embodiment, the dishwasher inner tank is divided into a plurality of splicing parts, which are spliced ​​together to form the dishwasher inner tank, instead of using the existing stamping method to form the inner tank structure, thereby preventing the plate from being highly stretched and having insufficient strength or even becoming waste.

[0086] Embodiment 3

[0087] Different from the above-mentioned embodiment, the inner liner body 200 in this embodiment is formed by integrally bending a plate, and the specific forming method is as follows.

[0088] like Figure 8 As shown, the inner tank body 200 includes a bottom wall 204 and a side panel assembly, wherein the bottom wall 204 and the side panel assembly are an integral piece, and the side panel assembly is bent and spliced ​​to form a side peripheral wall 220 of the dishwasher.

[0089] In this embodiment, the liner body 200 is formed by bending an integral plate, which reduces the length of the weld and simplifies the processing technology.

[0090] Preferably, the bottom wall 204 has a plurality of edges, and the side panel assembly includes plate bodies respectively connected to the edges of the bottom wall 204 , and the plate bodies are bent toward the same side of the bottom wall 204 to jointly form a side peripheral wall 220 of the dishwasher.

[0091] In the above solution, through the solution of the present invention, the inner tank body 200 of different shapes can be manufactured respectively, each plate is bent relative to the bottom wall 204, and two adjacent plates are spliced ​​to form the annular side wall 220 of the dishwasher.

[0092] Preferably, the bottom wall 204 is a quadrilateral plate, each of the four sides of the quadrilateral plate is connected to a plate body, the four plates are bent toward the same side of the bottom wall 204 to form a side wall 220 of the dishwasher, and the opposite sides of two adjacent plates are in contact and connected using a set process.

[0093] Preferably, the opposite sides of two adjacent plates are in contact and welded together.

[0094] Preferably, among the two adjacent plates on the liner main body 200, a connecting portion is provided on the side of one plate, and the plate is connected to the other plate via the connecting portion.

[0095] Preferably, the connecting portion includes a flange arranged on one side edge of the plate body, and after the two plates are bent relative to the bottom wall 204, the side edge of one plate body is attached to the flange of the adjacent plate body.

[0096] In the above scheme, through the design of the flange structure, two adjacent plates can be fitted and positioned, which is convenient for fixing by welding, and the flange has support and limit functions on the other plate, which facilitates the welding process.

[0097] The flange is formed by bending the edge of the plate toward the plane where the adjacent plate is located. When the liner body 200 includes four plates, the flange is formed by vertically bending the edge of the plate. The bending direction can be toward the side of the plate spliced ​​with it, or away from the side of the plate spliced ​​with it.

[0098] like Figure 3 He Ru Figure 8 As shown, the inner liner includes two first plates 8001 arranged on opposite sides of the bottom wall 204, and the other two plates of the inner liner are second plates 8002. The bottoms of the two first plates 8001 are provided with recessed surfaces 2033 / 2035 extending along the length direction of the plates and recessed in the direction of bending of each plate. The flanges are arranged on both side edges of the first plate 8001. After each plate is bent relative to the bottom wall 204, the edges on both sides of the two second plates 8002 are attached to the flanges.

[0099] Preferably, the contour lines of the edges on both sides 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 edges are uniform without protruding parts.

[0100] Preferably, the first plate body 8001 is stamped on one side connected to the bottom wall 204 to form a recessed surface 2033 / 2035 that gradually narrows toward the bottom wall 204 and is connected to the bottom wall 204, and the second plate body 8002 is stamped on one side connected to the bottom wall 204 to form a recessed surface 2033 / 2035 that gradually narrows toward the bottom edge and is connected to the bottom wall 204. After each plate body is bent, the edges of the recessed surfaces 2033 / 2035 of two adjacent plates are in corresponding contact and connected. In the above scheme, recessed surfaces 2033 / 2035 are also set on the two second plates 8002 corresponding to the recessed surfaces 2033 / 2035 on the first body, the recessed surface 2033 / 2035 of the first plate 8001 is connected to the recessed surface 2033 / 2035 of the second plate 8002, and the planes on the tops of the recessed surfaces 2033 / 2035 of the two are also connected accordingly, thereby avoiding the connection between the two adjacent plates through the arc surface and the plane, simplifying the splicing process.

[0101] In addition, this embodiment also provides a method for manufacturing the inner tank body 200 of the dishwasher in the first embodiment, comprising the following steps:

The first splicing portion 2012 and the second splicing portion 2013 are spliced ​​to form the side wall 220. A notch is provided on the first splicing portion 2012 and / or the second splicing portion 2013, and the notch forms an installation port 2011 for placing a detergent adding device after the first splicing portion 2012 and the second splicing portion 2013 are spliced.

[0112] Specifically, the first splicing portion 2012 includes a first splicing surface formed by vertically connecting the first side and the first bottom side, the second splicing portion 2013 includes a second splicing surface formed by vertically connecting the second side and the second bottom side, 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 in the same horizontal plane, and the notch forms an installation port 2011 for placing a detergent adding device during splicing, and the size of the notch can be set to different sizes and shapes according to the size of the detergent adding device.

[0113] For example, a notch may be opened on the first side of the first joining surface, and a notch may be opened at a corresponding position of the second side. When the first joining surface and the second joining surface are joined, the middle notch portion of the first side and the middle notch portion of the second side form an installation opening 2011 for placing a detergent adding device.

[0114] As an alternative to the above-mentioned scheme, a notch may be provided on one side of the first splicing surface or the second splicing surface. For example, a notch may be provided on one side of the first splicing surface. When the first splicing surface and the second splicing surface are spliced ​​together, the notch portion of the first splicing surface and the second splicing surface form an installation opening 2011 for placing a detergent adding device.

[0115] In this embodiment, an installation opening 2011 for placing a detergent adding device is formed at the position of the joint seam 2014, which reduces the length of the weld and can even eliminate the middle weld, which not only reduces the number of welding processes but also saves costs.

[0116] In this embodiment, the bottom wall 204 has an upwardly open accommodation space, the open end of the bottom wall 204 is connected to the bottom edge of the side wall 220 to form the inner tank body, and the bottom edge of the side wall is located above the water level in the inner tank to minimize water leakage.

[0117] Furthermore, a fixing plate is provided at the installation opening 2011 , and the fixing plate is located outside the inner tank body 200 . The detergent adding device is fixedly connected to the fixing plate by screws, and is thereby fixed to the inner tank body 200 .

[0118] Preferably, a sealing ring matching the shape and size of the mounting opening 2011 is provided between the fixing plate and the detergent adding device, so as to increase the sealing performance between the detergent adding device and the inner tank body 200 .

[0119] Embodiment 5

[0120] This embodiment will introduce the specific structure of the inner pot bottom wall 204. In this embodiment, the bottom wall 204 of the inner pot body 200 is in a gathered shape that is gathered toward the bottom of the inner pot, so as to facilitate the water flow in the inner pot body 200 to gather. Specifically, the lower edge of the side peripheral wall 220 is arranged circumferentially around the outer edge of the bottom wall 204 to form a receiving cavity with an open top, and the bottom wall 204 is arranged obliquely downward along the lower edge of the side peripheral wall 220, forming a gathered shape that is gathered toward the bottom of the inner pot, so as to facilitate the water flow in the inner pot body 200 to gather downward.

[0121] Further, such as Fig.11 As shown, a drainage hole 2041 is opened on the bottom wall 204 of the inner tank, and the drainage hole 2041 is located below the plane where the lower edge of the side peripheral wall 220 is located. The through hole 2041 and the plane where the lower edge of the peripheral wall 220 is located form a certain height difference, which is convenient for water to be discharged downward. The bottom wall 204 extends downwardly along the lower edge of the side peripheral wall 220 toward the direction of the drainage hole 2041. The bottom wall 204 is in a convergent shape toward the drainage hole 2041, which is convenient for the water in the inner tank to be gathered and discharged toward the drainage hole 2041.

[0122] In this embodiment, the bottom wall 204 includes four straight surfaces 2042 that are respectively connected to the lower edge of the peripheral wall 220 and the through hole 2041 and are obliquely arranged. Four reinforcing ribs are formed between the straight surfaces 2042 that are inclined downward, thereby strengthening the structure of the inner liner itself.

[0123] Preferably, the bottom wall 204 includes a straight surface 2042 and a transition curved surface 2043 which are respectively connected to the lower edge of the peripheral wall 220 and the through hole 2041 and are inclined. The transition curved surface 2043 and the straight surface 2042 are arranged at intervals to form the bottom wall 204 of the inner container.

[0124] In this embodiment, the through hole 2041 can be located at any position of the bottom wall 204, but in order to increase the overall aesthetics of the liner body 200 and to enable the accumulated water in the liner to be discharged in time, it is more preferred that the through hole 2041 is opened at the center of the bottom wall 204, the transition curved surface 2043 can be located at the midline position of the bottom wall 204, the through hole 2041 is a center hole located at the intersection of the midline of the bottom wall 204, and the straight surface 2042 is located between two adjacent transition curved surfaces 2043.

[0125] As a more preferred scheme of the above scheme, the transition curved surface 2043 is located at the diagonal position of the bottom wall 204 of the inner tank, the through hole 2041 is a central hole located at the intersection of the diagonals of the bottom wall 204, and the straight surface 2042 is located between two adjacent transition curved surfaces 2043. The transition curved surface 2043 arranged between two adjacent straight surfaces 2042 can prevent some debris from being mixed between the gaps due to the small angle between the two adjacent straight surfaces 2042, thereby polluting the internal space of the dishwasher and making it inconvenient to clean.

[0126] Specifically, the flat surface 2042 is in a trapezoidal shape, and the trapezoid includes a waist 20423 , an upper base long side 20421 , and a lower base short side 20422 , and the lower base short side 20422 is an arc shape that is concave toward the upper base long side 20421 . The transition curved surface 2043 includes a right-angled side 20431, an arc-shaped side 20432 recessed toward the right-angled side 20431, and two straight sides 20423 connected at both ends of the right-angled side 20431 and the arc-shaped side 20432. A smooth curved surface protruding toward the outside of the inner bottom 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 curved surface 2043 gradually increases in the direction away from the through hole 2041 to form a fan-shaped groove-shaped transition curved surface 2043, thereby being able to collect water flow over a larger area. Furthermore, the arc-shaped side 20432 and the lower bottom short side 20422 have the same curvature. The right-angled side 20431 is located at a right angle at the top angle of the bottom wall 204. The two sides of the right-angled side 20431 form a part of the outer edge of the bottom wall 204. The waist 20423 of the flat surface 2042 and the flat edge 20423 of the transition curved surface 2043 are connected as one body, the two right-angled edges 20431 of the transition curved surface 2043 and the upper bottom long edge 20421 of the flat surface 2042 form the outer edge of the bottom wall 204, and the arc edge 20432 and the lower bottom short edge 20422 are connected as one body to form a through hole. The transition curved surface 2043 added between the two flat surfaces 2042 forms eight reinforcing ribs, which has four more reinforcing ribs than the direct connection between the two flat surfaces 2042 and the flat surface 2042, thereby enhancing the strength and rigidity of the liner structure.

[0127] In this embodiment, the through hole 2041 may be circular or elliptical or square. In this embodiment, the circular through hole 2041 is used as an example for explanation. The bottom wall 204 in this embodiment is formed as a whole by stamping from a square or rectangular plate. The plate is stamped toward the center by a stamping process to form four straight surfaces 2042 symmetrical along the diagonal direction. Four reinforcing ribs are formed at the diagonal position to increase the strength of the inner liner, and a through hole 2041 is opened at the center of the plate. The through hole 2041 can not only be used to discharge the accumulated water in the inner liner, but also to install a spray device.

[0128] Furthermore, a smooth curved surface protruding toward the outside of the inner liner bottom is formed by stamping at the junction of two adjacent straight surfaces 2042, forming a transition curved surface 2043. Two reinforcing ribs are formed at the connection between the transition curved surface 2043 and the straight surface 2042, further enhancing the strength and rigidity of the inner liner structure. The arc length of the transition curved surface 2043 gradually increases in the direction away from the through hole 2041, so as to facilitate the collection of more water flow. Compared with the straight surface 2042, the set transition curved surface 2043 can slow down the water flow speed, prevent splashing, and facilitate collection.

[0129] In another solution, a transition curved surface 2043 can be formed between two adjacent straight surfaces 2042 by using a chamfering machine to round off the corners. By adjusting the chamfering angle of the chamfering machine, the arc length of the rounded corner structure can be gradually reduced in the direction approaching the through hole 2041, so that the transition curved surface 2043 forms a converging shape that gradually narrows toward the through hole 2041, which facilitates the gradual converging and discharge of water. The transition curved surface 2043 formed by chamfering can strengthen the structure of the inner liner itself, and the transition curved surface 2043 has a groove-shaped accommodating space for easy diversion.

[0130] The bottom wall 204 of the dishwasher provided by the present invention is integrally formed by stamping, has a simple structure, is easy to manufacture, and improves production efficiency. The radial four-sided prism-shaped bottom wall 204 is formed by stamping, which not only strengthens the structure of the inner tank itself, but also facilitates the water flow to the middle.

[0131] As a variation of this embodiment, the bottom wall 204 is formed by splicing a plurality of plates obliquely downward toward the position of the through hole 2041 of the bottom wall 204, with a plurality of fillets at the splicing position, and the plates are spliced ​​in a smooth transition, and the arc length of the fillets gradually increases in the direction away from the through hole 2041. Specifically, the bottom wall 204 is formed by splicing four plates symmetrical along the diagonal line of the bottom wall 204 toward the through hole 2041, and the edges of the plates form radial ribs at the diagonal position of the bottom wall 204 to facilitate the gathering of water flow.

[0132] Embodiment 6

[0133] When the dishwasher is performing cleaning work, a sprayer for cleaning dishes is arranged in the inner tank body 200, and the sprayer includes a spray arm with multiple spray holes. The spray arm rotates or swings in a 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 tank body 200 may hinder the movement of the spray arm of the sprayer, so that the spray range is limited, resulting in poor washing effect and incomplete cleaning of the dishwasher.

[0134] In order to solve the above problem, based on the sixth embodiment, this embodiment provides an avoidance structure 2003 in the inner tank body 200 for avoiding the spray arm of the sprayer in the dishwasher.

[0135] A avoidance structure 2003 for avoiding the sprayer in the dishwasher is provided in the inner tank body 200. Figures 12 to 16 As shown, the sprayer is installed at the bottom of the inner tank body 200. Specifically, the sprayer is installed at the through hole 2041 of the bottom wall 204. The bottom of the inner tank body 200 is provided with an avoidance structure 2003 for avoiding the sprayer.

[0136] Specifically, Fig.12 and Fig.13 As shown, the avoidance structure 2003 described in this embodiment is a profiled structure arranged at the bottom of the liner body 200, and the profiled structure is used to avoid the sprayer. The profiled structure is a concave surface at the junction of the bottom wall 204 and the side wall 220 that is concave toward the outside of the liner body 200. Fig.14 and Fig.15 As shown, the profiled structure is arranged at the midline end points on both sides of the bottom wall 204. The profiled structure expands outward to avoid the arms at both ends of the sprayer, thereby expanding the spraying range and avoiding the generation of dead corners in the spraying process, which leads to poor washing effect and incomplete cleaning of the dishwasher.

[0137] In the above scheme, the bottom wall 204 can be square in shape, and the corrugated structure is arranged at the midpoints of the four sides of the square bottom wall. The bottom wall 204 can also be rectangular in shape, and the outer edge of the bottom wall 204 includes two long sides and two short sides arranged oppositely, and the corrugated structure is arranged at the midline end points of the two long sides.

[0138] like Fig.16 As shown, in this embodiment, the pressure-profile structure is arc-shaped or crescent-shaped and is recessed toward the outside of the inner tank body 200, and the shape of the pressure-profile structure matches the rotation trajectory of the end of the spray arm of the sprayer.

[0139] 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 of Examples 1 to 6 are all provided with an outward convex structure.

[0140] Embodiment 7

[0141] This embodiment will introduce the convex structure provided on the side wall 220 of the inner container body 200. Figure 1-5 As shown, the liner body 200 includes a bottom wall 204 and a side wall 220 arranged on the bottom wall 204 and surrounding the bottom wall to form the liner body 200. The side wall 220 is arranged as a convex structure protruding from the inside of the liner body 200 to the outside.

[0142] In the above solution, the side wall 220 of the inner liner body 200 is configured as a convex structure from the inside of the inner liner to the outside, thereby increasing the capacity of the inner liner and achieving capacity expansion of the inner liner.

[0143] Preferably, the inner pot body 200 is slidably disposed in a housing or bracket of the dishwasher, and the side peripheral wall 220 includes two side walls 203 extending along the sliding direction of the inner pot, and the two side walls 203 are both configured as convex structures protruding in a direction away from the opposite side wall.

[0144] In the above solution, the two side walls are relatively arranged to be convex structures, thereby increasing the size of the inner container in a direction perpendicular to the sliding direction of the inner container and increasing the internal space of the inner container body 200.

[0145] The inner container body 200 is composed of a bottom plate and a side plate assembly arranged around the bottom plate, and the side plate assembly includes a front plate corresponding to the front wall, a rear plate corresponding to the rear wall, and side plates corresponding to the side walls, which surround the side peripheral wall 220. The middle part of the side plate protrudes outward, and the side plates are bent and extended toward the front plate and the rear plate on both sides along the sliding direction of the inner container.

[0146] In the above scheme, the configuration of the side panel is obtained by stamping and forming a large area in the middle of the side panel, forming a structure in which the middle part is convex and the peripheral side is recovered, thereby increasing the internal space of the liner body 200. Specifically, the side panel is stamped with a convex molding 2034 in the opposite direction to the opposite side panel, forming a shell structure in which the bottom wall 204 is convex and the peripheral wall extends to one side of the opposite side panel. In this way, a large area of ​​stamping is performed in the middle of the side panel, which increases the internal space of the liner.

[0147] Preferably, the side panels are respectively provided with second extension surfaces 2032 that are bent toward the front wall 201 and the rear wall 202 to connect the front panel and the rear panel respectively along the sliding direction of the inner container, and the middle part of the side panels is a plane structure, and the two sides of the plane structure are respectively smoothly connected to the second extension surfaces 2032 of the corresponding sides through the first curved surface. The middle part of the side panels is stamped to form a convex plane, and the curved surface of the plane transitions to the side edge of the side panels, so that the stamping strength of the side panels is small, the inner container manufactured is high in strength and good in quality, and the inner container body 200 with smooth transition has good overall gloss and beautiful appearance. Through the design on the first extension surface, the joint position is transferred from the corner between the side panel and the front panel and the rear panel to the plane where the front panel or the rear panel is located, which facilitates and simplifies the connection between the side panel and the front panel and the rear panel.

[0148] The middle part of the side panel is a plane, and the plane transitions to the edge of the side panel through a smooth first arc surface on both sides along the sliding direction of the inner liner. The arc surface of the plane in the middle of the side panel transitions to the side edge of the side panel, so that the stamping strength of the side panel is small, the inner liner is high in strength and good in quality, and the inner liner with smooth transition has a good overall gloss and beautiful appearance.

[0149] In this embodiment, the liner body 200 is a drawer structure, and the liner body 200 includes a front wall 201 and a rear wall 202 respectively connected to the two ends of the two side walls 203, and the two sides of the side walls 203 are respectively provided with second extension surfaces 2032 that bend and extend toward the front wall 201 and the rear wall 202, and the second extension surfaces 2032 are connected to the corresponding front wall 201 / rear wall 202, and the bottom wall 204 of the liner body 200 is connected and transitioned to the first extension surface 2031 through the smooth first arc surface. Through the design of the second extension surface 2032, the joint position is transferred 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 the rear wall 202 is located, which facilitates and simplifies the connection between the side wall 203 and the front wall 201 / rear wall 202.

[0150] See also Figure 3 and Figure 4 As shown, in one solution, after the side panel is stamped and formed 2034, a concave surface 2035 that is concave toward the inner tank is formed at the bottom of the side panel, and the concave surface 2035 is used to avoid the slide rail of the dishwasher.

[0151] In the above solution, the inner tank is formed with a recessed surface 2035 for installing the dishwasher rail, thereby making full use of the space in the dishwasher shell and facilitating the expansion of the inner tank.

[0152] Preferably, the recessed surface 2035 includes a recessed surface 2035 gradually indented from top to bottom into the inner liner body 200 and a vertical surface extending downward from the end of the recessed surface, and the cross-sectional profile of the recessed surface 2035 longitudinally cut through the vertical surface perpendicular to the side plate on which it is located includes, from top to bottom, a first curve 20351 with a center of curvature inside the inner liner body 200 and a second curve 20352 with a center of curvature outside the inner liner, and the first curve 20351 and the second curve 20352 have a smooth transition. 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 edge of the convex profile, or the two bends of the recessed surface 2035, has the same tensile strength, the plate is evenly stretched, and the thickness is uniform, thereby preventing local transitional stretching from affecting the quality of the inner liner.

[0153] like Figure 5 and Figure 6As shown, in another structure, the concave surface 2035 is a concave surface 2035 directly punched from the bottom of the side plate toward the inside of the inner tank body 200, and the concave surface 2035 includes a horizontal bending surface 20331 formed by bending the bottom wall of the side plate from top to bottom toward the inside of the inner tank, and a vertical bending surface 20332 formed by bending the end of the horizontal bending surface 20331 vertically downward, and the horizontal bending surface 20331 and the vertical bending surface 20332 are connected and transitioned by a smooth arc surface. This structure is similar to Figure 4 The structure is different. Figure 4 In the middle, the concave surface is indirectly formed by the convex pressing of the stamping. Because the pressing profile is large, the stamping strength cannot be high, so it has no horizontal bending surface 20331. Figure 6 Because it is a directly stamped concave surface, the stamping area is small, and a concave surface 2035 having a horizontal bending surface 20331 and a vertical bending surface 20332 can be stamped out. In this solution, the cooperation of the horizontal bending surface 20331 and the vertical bending surface 20332 is more conducive to installing the slide rail.

[0154] Preferably, the bottom edge of the side plate is provided with a second extension surface 2031 that bends and extends toward the bottom plate, and the recessed surface 2035 smoothly transitions with the second extension surface 2031. The second extension surface 2031 is connected to the bottom wall 204 of the liner body 200.

[0155] Furthermore, the front wall 201 and / or the rear wall 202 of the liner body 200 are also similar to the two side walls 203, and are configured to be convex toward the outside of the liner, thereby achieving the expansion of the liner. The structure thereof may be similar to the two side panels mentioned above, and will not be described in detail here.

[0156] Embodiment 8

[0157] This embodiment will introduce the specific structure of the inner bottom of the inner body 200. Fig.17As shown, this embodiment provides an inner tank bottom structure of a dishwasher inner tank body 200, including an inner tank body 200 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 2101 and an inner tank bottom side wall arranged around the inner tank bottom wall, the inner tank bottom side wall is transitionally connected to the inner tank bottom wall 2101, the inner tank bottom side wall is inclined toward the outer side of the inner tank body 200, and a certain transition inclination angle is formed between the inner tank bottom side wall and the inner tank bottom wall normal, and at least one transition inclination angle between the inner tank bottom side wall and the inner tank bottom wall 2101 is smaller than the transition inclination angle between the other inner tank bottom side walls and the inner tank bottom wall 2101. The inner tank bottom is integrally stamped, and a draft angle needs to be set on the inner tank bottom for the sake of demoulding. At the same time, considering that a filter net needs to be installed at the bottom of the inner tank, and the installation area of ​​the filter net is too small, it is easy to cause secondary pollution. Therefore, the transition inclination angle between the side wall of the inner tank bottom where the filter net is installed and the bottom wall 2101 of the inner tank bottom is smaller than the transition inclination angle between the other side walls of the inner tank bottom and the bottom wall 2101 of the inner tank bottom, so as to leave enough space for the installation of the filter net.

[0158] Furthermore, the inner tank body 200 is connected to the door body 301, and the inner tank bottom side wall includes an inner tank bottom front wall 2111 close to the door body 301, and the transition inclination angle between the inner tank bottom front wall 2111 and the inner tank bottom bottom wall 2101 is smaller than the transition inclination angle between the other inner tank bottom side walls and the inner tank bottom bottom wall 2101. The installation position of the filter is set between the inner tank bottom front wall close to the door body and the inner tank bottom bottom wall, and the inner tank bottom front wall does not need to avoid the slide rail groove, and a smaller inclination angle can be set as much as possible to leave a large enough installation space to install a large filter.

[0159] The inner bottom side wall includes an inner bottom left wall 2111 and an inner bottom right wall 2113 connected to both ends of the inner bottom front wall, and an inner bottom rear wall 2114 opposite to the inner bottom front wall 2111. The transition angle between the inner bottom front wall 2111 and the inner bottom bottom wall 2101 is smaller than the transition angle between the inner bottom left wall 2112 and the inner bottom bottom wall 2101, the transition angle between the inner bottom right wall 2113 and the inner bottom bottom wall 2101, and the transition angle between the inner bottom rear wall 2114 and the inner bottom bottom wall 2101. The inner body 200 is designed as a hexahedral structure, which is suitable for most bowl baskets and is also convenient for the installation of supporting facilities.

[0160] Specifically, the transition angle between the left wall 2111 of the inner liner bottom and the inner liner bottom wall 2101, the transition angle between the right wall 2113 of the inner liner bottom and the inner liner bottom wall 2101, and the transition angle between the rear wall 2114 of the inner liner bottom and the inner liner bottom wall 2101 can be set the same or different. Considering the regular shape of the inner liner bottom, it is more conducive to the manufacture of the inner liner bottom stamping die. In this embodiment, the transition angle between the left wall 2111 of the inner liner bottom and the inner liner bottom wall 2101, the transition angle between the right wall 2113 of the inner liner bottom and the inner liner bottom wall 2101, and the transition angle between the rear wall 2114 of the inner liner bottom and the inner liner bottom wall 2101 are all set the same.

[0161] Furthermore, a mounting position 2102 for mounting a filter is provided on one side of the bottom wall 2101 of the inner tank near the front wall of the inner tank bottom. A mounting opening 2103 for mounting a shower is provided at the center of the bottom wall 2101 of the inner tank bottom, and the mounting position 2102 is provided between the mounting opening 2103 of the shower and the front wall 2111 of the inner tank bottom. One end of the mounting position 2102 is provided near the mounting opening 2103 of the shower, and the other end is provided near the front wall 2111 of the inner tank bottom, so as to ensure that the mounting position 2102 of the filter is as large as possible, so that the filter is as large as possible, and to avoid secondary contamination caused by setting the filter too small.

[0162] The inner tank structure of the dishwasher further comprises a bottom bracket 500 for supporting the inner tank body 200, and a slide rail groove 600 for installing a slide rail is arranged on the bottom bracket 500, and the transition angle between the inner tank bottom side wall near the slide rail groove 600 and the inner tank bottom bottom wall of the inner tank bottom is greater than the transition angle between the other inner tank bottom side walls and the inner tank bottom bottom wall, so that the inner tank bottom bottom wall 2101 and the inner tank bottom side wall avoid the slide rail groove 600.

[0163] Specifically, the slide rail grooves 600 are respectively arranged on the two sides of the bottom bracket 500 corresponding to the left wall 2112 and the right wall 2113 of the bottom of the inner container.

[0164] Furthermore, a dishwasher water channel is arranged outside the inner tank bottom rear wall 2114, and a transition inclination angle between the inner tank bottom rear wall 2114 and the inner tank bottom bottom wall 2101 is used to avoid the dishwasher water channel arrangement.

[0165] Furthermore, the inner container body 200 further includes a side peripheral wall 220 disposed around the inner container bottom, and a connection portion connected to the inner container bottom side wall is disposed at the lower edge of the side peripheral wall 220. The connection portion is disposed to facilitate the connection between the inner container bottom and the inner container side peripheral wall 220.

[0166] Specifically, the connection portion includes a connection surface connected to the corresponding side wall of the bottom of the inner container, the connection surface is arranged parallel to a side surface of the corresponding side wall of the bottom of the inner container, and the connection surface is fitted and connected to a side surface of the edge of the bottom of the inner container. The connection surface and the side surface of the bottom of the inner container are welded and connected, and the connection surface is arranged parallel to a side surface of the corresponding side wall of the bottom of the inner container, which is convenient for welding.

[0167] The connecting portion also includes a limiting surface, wherein the lower edge of the side wall is first bent away from / close to one side of the inner liner body to form a limiting surface, and the free end of the limiting surface is then bent and extended toward the inner liner bottom 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 fits 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.

[0168] Embodiment 9

[0169] In order to facilitate the stable placement of the bowl basket, a support structure is arranged inside the inner container body 200. This embodiment will introduce the specific arrangement position and specific structure of the support structure. Fig.18 As shown, the liner body 200 has a accommodating chamber with an opening at the top, in which a bowl basket can be placed. A supporting structure for supporting the bowl basket is provided on the inner wall of the liner body 200, so that the bowl basket can be placed in the liner body 200 more stably without shaking, and at the same time, the bowl basket is prevented from being placed directly on the bottom wall 204 of the liner body 200, which would cause the bottom of the bowl basket to wear the bottom wall 204 of the liner body 200 due to shaking.

[0170] The inner container body 200 includes a bottom wall 204 and a side wall surrounding the bottom wall, and the support structure is arranged at the connection position between the bottom wall 204 and the side wall of the inner container body 200, or the support structure is arranged on the side wall of the inner container body 200. In this embodiment, the support structure is arranged at the connection position between the bottom wall 204 and the side wall of the inner container body 200, so that the support structure and the side wall 220 together form the support plane of the bowl basket, and the side wall 220 limits the left and right displacement of the bowl basket, so that the bowl basket is placed more stably; at the same time, the space of the inner container body 200 is more effectively utilized.

[0171] Specifically, the bottom wall 204 and the side wall 220 are transitionally connected by a transition fillet structure, and the support structure is arranged on the transition fillet structure. The fillet structure connecting the bottom wall 204 and the side wall 220 is more conducive to demoulding, and the demoulding angle and the pressure forming of the support structure can be made in one piece during mold making, thereby improving production efficiency.

[0172] The support structure includes a plurality of support bodies 2044 disposed on the inner wall of the liner body 200. In order to stably place the bowl basket, the upper surfaces of the plurality of support bodies 2044 are flush to form a support plane for supporting the bowl basket.

[0173] The support body 2044 can be a component independent of the liner body 200, and can be installed at the corresponding position of the liner body 200 when needed. The support body 2044 can also be integrally formed with the liner body 200. Considering the connection strength and convenience of the support body 2044 and the liner body 200, the support body 2044 in this embodiment is integrally formed with the liner body 200. The support body 2044 is a protruding structure protruding from the liner wall of the liner body toward the inside of the liner, and the protruding structure is formed by stamping; the support body and the liner body 200 are integrally formed, which 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 the support body and the liner body 200 being integrally formed also prevents the support body 2044 from being lost.

[0174] Specifically, the support structure is arranged corresponding to the slide rail groove 600 .

[0175] Furthermore, the bottom of the base 500 and the bottom of the liner body 200 are respectively provided with mutually cooperating limiting structures. The limiting structure includes a limiting part on the base and a limiting part on the bottom of the liner body 200. The limiting part can be provided on the bottom wall of the base or on the side of the slide rail groove of the base facing the liner body 200, or on the side wall of the base. Considering that the limiting part 2 must correspond to the setting of the limiting part 1, the liner body is provided on the bottom wall of the base or on the side of the slide rail groove of the base facing the liner body 200, taking into account that the setting of the limiting part 1 does not affect the use space inside the liner body 200. In addition, considering that the liner body 200 is supported on the slide rail, the limiting part 1 is provided on the side of the slide rail groove facing the liner body 200, which is more conducive to the transmission of the supporting force.

[0176] The first limiting part can be a support platform or a support column, and the second limiting part is a groove structure 2045 that cooperates with the support platform or the support column. In this embodiment, the first limiting part is a support platform, and the second limiting part that cooperates with it is a limiting groove. The support platform abuts against the limiting groove to limit the displacement of the liner body 200, and at the same time supports the liner body 200.

[0177] The limiting groove can be set separately or formed by punching the wall of the liner body 200. In order to have a better connection strength between the limiting groove and the liner body 200, the limiting groove is formed by punching the wall of the liner body. Considering the relationship between production efficiency and cost, the side of the protruding structure facing the bottom bracket 500 is a groove structure 2045 that matches the limiting part of the bottom bracket. The protruding structure and the limiting part are both set corresponding to the slide rail groove. The limiting part at the bottom of the liner body 200, namely the groove structure 2045, is arranged corresponding to the slide rail groove to facilitate the transmission of the supporting force of the slide on the bottom bracket to the bottom bracket 500 and the liner body 200. At the same time, the convex structure formed by the inner liner wall of the liner body 200 protruding toward the inside of the liner serves as a supporting structure, and the side facing the bottom bracket 500 is the groove structure 2045 matched with the limiting structure of the bottom bracket 500. The supporting structure also serves as a supporting and limiting structure for the bottom of the liner and the bottom bracket 500. It has multiple uses and eliminates the process of manufacturing the two limiting parts.

[0178] Furthermore, the first slide rail groove and the second slide rail groove are respectively provided on opposite sides of the base 500, and a plurality of first protrusion structures are provided on the inner wall of the inner container body 200 corresponding to the first slide rail groove, and a plurality of second protrusion structures are provided corresponding to the second slide rail groove. Preferably, the first protrusion structure and the second protrusion structure are symmetrically provided, and it is appropriate to provide two first protrusion structures and two second protrusion structures respectively, so as to ensure the stable placement of the bowl basket and reduce the workload of stamping the protrusion structure.

[0179] Furthermore, the base 500 includes a base bottom wall and a base side wall, and the slide rail groove is arranged at the connection position between the base bottom wall and the base side wall. The slide rail groove is arranged on the base instead of the guide rail being arranged on the base, so that the guide rail is prevented from protruding out of the inner container body 200, so that the space around the guide rail cannot be used, thereby increasing the use space of the inner container body 200.

[0211] The door body 301 includes an outer wall surface away from the inner tank body 200, and the four sides of the outer wall surface are folded toward the inner tank body 200 to form a plane, which serves as the thickness of the door body 301. The end of the plane is folded toward the center of the door body 301 to form an inner wall surface. The assembly structure is a convex rib set on the inner wall surface, and the door body 301 is formed by bending a plate. The manufacturing process is simple, the structure of the door body 301 is simple, the style is beautiful, and the manufacturing efficiency is improved.

[0212] The inner wall surface is parallel to the outer wall surface, and the inner wall surface includes four plates connected to the four edges of the outer wall surface, and two adjacent plates are connected in one piece. The convex ribs are located on the inner wall surface connected to the upper edge of the outer wall surface of the door body 301 and the side edges on both sides of the upper edge. The convex ribs on the inner wall surface connected to the upper edge of the outer wall surface of the door body 301 are straight and long strips arranged along the width direction of the door body 301, and the convex ribs on the inner wall surface connected to the side edges of the outer wall surface are generally n-shaped. This shape is convenient for limiting the outer edge of the connecting plate. The middle part of the convex rib is a straight and long strip arranged along the height direction of the door body 301. The two ends of the straight and long strip convex ribs are bent toward the inside of the door body 301, and the upper end is bent and flush with the straight and long strip convex ribs extending along the width direction of the door body 301.

[0234] The following several embodiments are used to introduce how the inner tank body of the dishwasher is connected to the base, how the base is connected to the outer plate, and the specific structure of the base.

[0235] Embodiment 14

[0236] This embodiment will introduce how to connect the inner liner body with the bottom bracket. Fig.31 As shown, a dishwasher inner tank structure includes a bottom bracket 500 and an inner tank body 200 disposed on the bottom bracket 500. A fixing structure is disposed on the inner tank body 200, and the inner tank body 200 is fixedly connected to the bottom bracket 500 through the fixing structure. The fixing structure is a connecting plate 2001 disposed at the bottom of the inner tank body 200 and extending toward the outside of the inner tank body 200, and the connecting plate 2001 is fixedly connected to the bottom bracket 500. The connecting plates 2001 can be arranged at intervals to ensure that the inner tank body 200 and the bottom bracket are fixedly connected while saving production materials.

[0237] In this embodiment, the connection plate 2001 is arranged all around the bottom wall of the inner container. The connection plate 2001 can be used as a fixing structure to fix the inner container body 200 and the bottom bracket 500, and can also be used as a closing structure to close the space between the inner container body 200 and the bottom bracket 500, so as to prevent water in the inner container body 200 from leaking out of the bottom bracket 500, so that users have a better use experience.

[0238] Specifically, the liner body 200 is formed by splicing an annular side plate and a bottom plate, and the connecting plate 2001 is formed by extending the outer wall of the annular side plate to the outside of the liner body 200, and / or by extending the peripheral wall of the bottom plate to the outside of the liner body 200, and / or by extending the splicing position of the annular side plate and the bottom plate to the outside of the liner body 200. In this embodiment, the connecting plate 2001 is formed by extending the splicing position of the annular side plate and the bottom plate to the outside of the liner body 200 to cover the splicing seam, and at the same time, the annular side plate and the bottom plate are connected to the bottom bracket, thereby increasing the connection strength between the entire liner body 200 and the bottom bracket.

[0239] Furthermore, the annular side plate and the bottom plate are connected by a splicing structure, wherein the splicing structure is formed by the first connection surface and the second connection surface formed by the side plate edge and the bottom plate edge being bent and extended toward the outer side of the inner tank, respectively, and the splicing structure is fixedly connected to the side wall of the bottom bracket as a connecting plate 2001. The splicing structure is used as the connecting plate 2001, which saves the process of manufacturing the connecting plate 2001 again and connecting the connecting plate 2001 with the inner tank body 200, thereby increasing the production efficiency of the inner tank structure of the dishwasher.

[0240] It also includes a connecting piece for fixedly connecting the liner body 200 and the base 500, and a mounting hole is provided on the connecting plate, and the connecting piece passes through the mounting hole and is fixedly connected with the base to fix the liner body 200 on the base 500. Specifically, the connecting piece is a connecting bolt, and a screw hole for assembling with the connecting bolt is provided on the base 500. The bolt connection makes the connection more stable, the connection method is simple, and the hazards caused by welding connection during the welding operation are avoided.

[0241] The inner wall of the base 500 is provided with a connecting boss 5033 matched with the connecting plate 2001, and the connecting boss 5033 and the connecting plate 2001 are fastened and connected by a connecting piece. The setting of the connecting boss 5033 is conducive to the connection and fixation of the connecting plate 2001 and the base 500. When the connecting plate 2001 contacts the connecting boss, it means that the installation position of the liner body 200 and the base 500 is reached, which increases the assembly efficiency of the liner body 200 and the base 500.

[0242] Furthermore, the base 500 includes a base side wall and a base bottom wall, and the base side wall and the base bottom wall together enclose a cavity for accommodating the bottom of the liner body, and the connecting boss 5033 can be arranged on the base side wall or the base bottom wall, and is arranged at a height higher than the bottom plate of the liner body 200. This avoids the vibration generated by the liner body 200 being directly transmitted to the base, thereby generating greater vibration noise.

[0243] In this embodiment, the connection boss 5033 is arranged on the side wall of the bottom bracket, and the connection boss 5033 is arranged corresponding to the mounting hole on the connection plate 2001; the connection boss 5033 can be arranged at intervals, or can be arranged along the circumference of the side wall of the bottom bracket. Specifically, the connection boss 5033 is arranged along the circumference of the side wall of the bottom bracket. This prevents the washing water from overflowing from the inner tank during the operation of the inner tank body 200, and the overflowing water overflows from the bottom bracket to affect the user experience.

[0244] Considering that the connection boss 5033 and the side wall of the base have better connection strength and fewer processing steps, the connection boss 5033 is formed by bending and extending the side wall of the base inwardly of the base.

[0245] Furthermore, a waterproof structure 501 is also provided on the side wall of the bottom bracket, and the waterproof structure 501 is formed by extending upward from the free end of the side wall of the bottom bracket, and the waterproof structure 501 is arranged higher than the connecting boss 5033, so as to further prevent the inner tank from leaking and overflowing.

[0246] Embodiment 15

[0247] This embodiment introduces the specific structure of the base. Fig.32As shown, a waterproof structure 501 for preventing water leakage and overflow of the inner tank is provided at the position of the bottom bracket 500 connected to the inner tank body 200. When water overflows from the inner tank body 200 during operation of the dishwasher, the provision of the waterproof structure 501 enables the overflow water to directly flow back into the chamber of the bottom bracket 500, effectively preventing the overflow water from splashing onto the outside of the dishwasher and wetting the dishwasher drawer, and preventing the overflow water from being brought out during the stretching process of the user, thereby contaminating the user's home environment and clothes.

[0248] The bottom bracket 500 includes a bottom bracket wall 502 and a bottom bracket side wall 503 connected to the bottom bracket wall 502 and extending upward, wherein the bottom bracket wall 502 and the bottom bracket side wall 503 enclose a receiving cavity opening upward. The liner body 200 is placed in the receiving cavity of the bottom bracket 500, and a bottom bracket connecting structure 504 for connecting the liner body 500 is arranged on the bottom bracket side wall 503, and the waterproof structure 501 is arranged around the bottom bracket connecting structure 504 to form an annular waterproofing of the bottom of the liner body 200. The overflow water is directly returned to the cavity of the bottom bracket 500, effectively preventing the overflow water from splashing to the outside of the dishwasher and wetting the dishwasher drawer, and preventing the overflow water from being brought out during the stretching process by the user, thereby preventing the user's home environment and clothes from being polluted.

[0249] The bottom support connecting structure 504 is arranged on the top of the bottom support side wall 503, and the waterproof structure 501 is arranged on the bottom support side wall 503, and the bottom is a water retaining rib surrounding the periphery of the bottom support connecting structure 504, and the water retaining rib is arranged on the outer edge of the top of the bottom support side wall 503, and extends circumferentially around the top of the bottom support side wall 503. The bottom support connecting structure 504 is arranged on the inner edge of the top of the bottom support side wall 503, and is arranged circumferentially around the top of the side wall. There is a gap between the waterproof structure and the bottom support connecting structure, so that water can flow back to the bottom support 500 accommodating cavity through the gap between the two.

[0250] The bottom bracket connection structure 504 is a guide rib 504 arranged on the top of the bottom bracket side wall 503. The side surface of the guide rib close to the center of the bottom bracket 500 is opposite to or in contact with the outer wall surface of the liner body 200. There are multiple guide ribs, which are arranged at intervals around the top of the bottom bracket side wall 503. When the liner body 200 is placed, it provides an installation guide for the liner body 200, which is beneficial to improving the assembly efficiency of the dishwasher. At the same time, the guide ribs arranged at intervals facilitate the collected water flow to flow back to the bottom bracket 500 accommodating cavity from the intervals between the guide ribs.

[0251] The top of the bottom support side wall 503 extends toward the outside of the bottom support 500 to form an annular plane surrounding the inside of the bottom support 500, the water retaining ribs are arranged on the outer edge of the annular plane, the bottom supporting structure 504 is arranged on the inner edge of the annular plane, and the annular plane is formed by bending, expanding and extending the top surface of the bottom support side wall 503 toward the outside of the bottom support 500, and the water retaining ribs are arranged on the outer edge of the annular plane.

[0252] Embodiment 16

[0253] This embodiment describes how the bottom bracket 500 is connected to the outer plate. Fig.33 As shown, it includes an inner tank body 200, a bottom bracket 500 and an outer plate. The inner tank body 200 is installed on the bottom bracket 500, and the outer plate is arranged on the outer side of the inner tank body 200. The bottom bracket 500 is provided with a connecting structure for connecting the outer plate. The outer plate is connected by the connecting structure instead of the inner tank body 200 being directly seated on the outer frame, which is convenient for transportation and more convenient for assembling the inner tank body 200 and the outer plate. Recalling that in Example 10, the upper end of the outer plate is fixedly connected to the connecting structure arranged at the open end of the inner tank body 200. In this embodiment, in order to more stably connect the outer plate and the inner tank body 200 to the bottom bracket, a connecting structure connected to the lower end of the outer plate is arranged on the bottom bracket 500 to avoid vibration and noise caused by the connection structure being fixed at only one end of the outer plate when the dishwasher is running, thereby affecting the user experience.

[0254] Furthermore, the connection structure includes a connection portion 5041 and an assembly portion 5042, wherein the connection portion 5041 is formed by extending the outer wall of the base toward the outside of the base 500, and the assembly portion 5042 is arranged on the connection portion 5041 for assembly and connection with the lower end of the outer plate. The connection structure can be fixedly connected to the outer wall of the base 500 or can be integrally formed with the outer wall of the base 500. This embodiment adopts a solution of integrally forming the connection structure with the outer wall of the base, which saves the process of making the connection structure and connecting the connection structure with the outer wall of the base, increases production efficiency, and strengthens the connection strength between the connection structure and the outer wall of the base.

[0255] The outer panel includes a door body 301, and the base 500 includes a base front wall close to the door body 301, and two base side walls respectively connected to the two ends of the base front wall. The connecting structure is respectively arranged on the two opposite base side walls, and is used to connect the bottom ends of the two outer panels 302, so that the outer panels 302 are firmly fixed to avoid vibration and noise.

[0256] Specifically, the side wall of the bottom bracket is integrally extended toward the outside of the bottom bracket in the horizontal direction to form a connecting portion 5041, and the assembly portion 5042 is integrally extended along the horizontal direction of the connecting portion 5041, or is disposed at intervals. In this embodiment, the assembly portion 5042 is integrally extended along the horizontal direction of the connecting portion 5041 to increase the connection strength between the outer plate and the bottom bracket.

[0257] In another embodiment, the side wall of the base extends at a certain length in the length direction to form a plurality of connection parts 5041, and an assembly part 5042 is provided on each connection part 5041, so as to realize the connection function between the outer panel and the base 500 and reduce the production cost at the same time.

[0258] Furthermore, the assembly portion 5042 is a plug-in rib arranged on the connecting portion 5041, and a plug-in groove for matching with the plug-in rib is provided at the bottom of the outer panel. The plug-in matching is used to limit the left and right and downward displacement of the outer panel. Looking back at the connection structure set at the open end of the inner liner body 200 in Example 10 to limit the upward displacement of the outer wall, the two cooperate with each other to tightly fix the outer panel to the outside of the inner liner body 200.

[0259] Specifically, the distance between the plugging rib close to the side wall of the bottom bracket and the outer surface of the side wall of the bottom bracket is greater than or equal to the groove wall thickness of the plugging groove. In the present invention, the distance between the plugging rib close to the side wall of the bottom bracket and the outer surface of the side wall of the bottom bracket is equal to the groove wall thickness of the plugging groove. The side wall of the bottom bracket can be used as a positioning structure. When the plugging groove at the lower part of the outer plate is plugged with the assembly part 5042, it can first be pressed against the side wall of the bottom bracket and then directly pushed down along the side wall of the bottom bracket to successfully plug the plugging groove and the plugging rib, which reduces the difficulty of assembly for workers and increases assembly efficiency.

[0260] Furthermore, the outer plate includes an outer side plate 302 , the upper end of the outer side plate 302 is fixedly connected to the open end of the liner body 200 , and the lower end of the outer side plate 302 is fixedly connected to the connection structure of the bottom bracket 500 .

[0261] The connection structure is arranged on the outer side wall of the bottom bracket near the slide groove 600. Specifically, the bottom bracket side wall on the bottom bracket 500 located outside the slide groove 600 extends downward to form an extension portion higher than the open end of the slide groove 600, and the extension portion extends toward the outside of the bottom bracket 500 to form a connection portion 5041. The bottom bracket side wall also serves to shield the slide groove 600, preventing the slide groove from being exposed to people's field of vision and affecting the aesthetics of the inner tank structure of the dishwasher.

[0262] Embodiment 17

[0263] This embodiment introduces the cooperation between the inner container body 200 and the supporting structure 506 of the base 500. Figure 35-36 As shown, the support structure is arranged on the side of the slide rail groove 600 facing the inner container 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.

[0264] Specifically, the base 500 includes a base bottom wall 502 and a base side wall 503, and the base side wall 503 is circumferentially arranged around the base bottom wall 502 to form a receiving space that can accommodate the bottom of the inner tank body 200. The lower part of the two outer side walls of the base 500 parallel to the stretching direction of the dishwasher is provided with a slide rail groove 600 recessed toward the inner tank body 200, and the inner wall of the base side wall 503 is provided with a support structure 506 matched with the bottom of the inner tank body 200. The support structure 506 not only supports the inner tank body 200, but also transmits the force between the base 500 and the inner tank body 200 when the dishwasher is stretched.

[0265] The support structure 506 in this embodiment is a support platform arranged at the bottom of the bottom support side wall 503. In order to improve the support stability of the support platform on the liner body 200, there are multiple support platforms, and the support platforms are evenly distributed on the inner wall of the bottom support side wall 503 in the circumferential direction. The support platform includes a support platform plane portion 5061 integrally arranged with the bottom support side wall 503, the bottom wall of the liner body 200 is located on the support platform plane portion 5061, and the top of the support platform is in contact with the bottom surface of the liner body 200. By setting the top of the support platform as a plane, it is beneficial to increase the contact area between the support platform and the bottom of the liner body 200, thereby facilitating the effectiveness and stability of the support of a single support platform.

[0266] The support platform plane portion 5061 includes a plane formed by a straight section 50611 and U-shaped curved sections 50612 connected at both ends of the straight section 50611 , and the straight section 50611 is fixedly connected to the inner wall of the bottom support side wall 503 .

[0267] Specifically, the bottom bracket side wall 503 described in this embodiment includes a vertical plate 5031 and an inclined plate 5032 whose upper end of the vertical plate 5031 transitions to the outside of the inner liner. The inclined plate 5032 is circumferentially arranged around the upper edge of the vertical plate 5031 to form a receiving space with an upper opening diverging outward. The bottom of the inner liner body 200 is located in the receiving space of the bottom bracket 500. In this embodiment, the straight section 50611 of the plane portion 5061 of the support structure 506 is horizontally fixedly arranged on the inner wall of the inclined plate 5032, and the support platform also includes a reinforcing rib 5062 integrally arranged with the plane portion 5061. The reinforcing rib 5062 is a supporting surface that smoothly transitions downward along the outer edge of the U-shaped curved section 50612 of the plane portion 5061 and is fixedly connected to the inner wall of the inclined plate 5032. The reinforcing rib 5062 is arranged to strengthen the stability of the support platform to prevent bending and deformation when supporting the inner liner body 200.

[0268] In order to further improve the stability of the cooperation between the support structure 506 and the bottom of the liner body 200, a positioning structure that cooperates with the support structure 506 is provided at the junction of the bottom wall 204 and the side wall 220 of the liner body 200 to increase the stability between the liner body 200 and the bottom bracket 500. The positioning structure is the groove structure 2045 in the ninth embodiment. Through the setting of the positioning structure, the top of the support structure 506 can stably abut against the bottom of the liner body 200. Even when the liner body 200 vibrates, the support structure 506 will not be separated from the bottom of the liner body 200, thereby greatly increasing the support stability of the support structure 506.

[0269] Specifically, the positioning structure is a groove structure 2045 that is recessed into the inner tank body 200 and is disposed at the junction of the bottom wall 204 and the peripheral wall of the inner tank body 200, and the groove structure 2045 matches the shape and size of the support structure 506. The positioning structure 700 in this embodiment is a press-formed structure formed directly by a stamping process, which is simple in process and manufacturing. At the same time, the formed press-formed structure can not only cooperate with the support structure 506 to prevent the bottom bracket 500 from separating from the inner tank body 200, but also play a role in supporting the shelves, bowl baskets, etc. in the dishwasher.

[0270] In another embodiment, the support platform is arranged on the side of the slide rail groove 600 facing the liner body 200, and the positioning structure, that is, the groove structure 2045, arranged on the liner body 200 is arranged corresponding to the support platform. The liner body 200 is supported on the slide rail through the slide rail groove 600, and the support platform is used to limit the support of the liner body. The support platform is arranged on the slide rail groove 600 to facilitate the transmission of force.

[0271] In order to reduce the transmission of vibration and noise of the inner tank body 200 during the pulling process, the support platform also includes a plastic shock-absorbing pad attached to its outer surface. When the vibration of the inner tank body 200 is transmitted to the support platform, the vibration is buffered and absorbed by the support platform due to the elasticity of the support platform, thereby effectively blocking the transmission of vibration, thereby reducing the generation of noise, which is conducive to reducing the noise of the dishwasher.
