Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a dishwasher inner container and a manufacturing method thereof. Background Art

[0002] A dishwasher is a device that automatically washes tableware such as bowls, chopsticks, plates, dishes, knives, and forks. There are various types of household dishwashers on the market, including cabinet-type, tabletop-type, and sink-integrated types. However, dishwashers often take up a large amount of kitchen space, causing inconvenience to users. Drawer-type dishwashers are now available on the market. Drawer-type dishwashers are arranged in a housing or bracket that can be pushed in and out. Drawer-type dishwashers require guide rails for sliding. If guide rails are installed on both sides or at the bottom of the inner tank, the size of the inner tank that can be manufactured is adversely affected, wasting some space. Some existing patents mention providing a recessed portion on the bottom plate of the inner tank to install the guide rail assembly. However, this structure increases the difficulty of manufacturing the inner tank bottom plate. In order to form the recessed portion, the inner tank bottom must first be punched to form an upwardly extending side portion, and then the recessed portion must be punched on the side portion. This multiple high-stretching process affects product quality and increases processing difficulty.

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

[0051] In the above scheme, the inner container is provided with recessed surfaces for mounting guide rails, which saves the internal space of the dishwasher, is beneficial to the expansion of the inner container, and the recessed surfaces are arranged on the side plates, which has little impact on the structural strength of the inner container.

[0052] The first splicing component comprises a bottom plate and two second side plates located on the opposite sides of the bottom plate, and the inner container comprises two second splicing components, which are two first side plates of the inner container, and the two first side plates are connected to the two second side plates on the two sides of the first splicing component, respectively, and the recessed surfaces are arranged on the two first side plates.

[0053] The first side plate comprises a flat portion and a curved portion smoothly connected to the second side plate on both sides of the flat portion, and the recessed surface extends along the length direction of the side plate and comprises a first recessed surface 20333 arranged on the flat portion and a second recessed surface 20334 arranged on the curved portion, and the first recessed surface and the second recessed surface are smoothly connected.

[0054] Preferably, the bottom of the first recessed surface is provided with a first bent surface 2031 bent and extending toward the bottom plate, and the first bent surface 2031 is spliced with the corresponding side edge of the bottom plate.

[0055] Preferably, the second side panel (see 203) includes a plate-like body and a first transition curved surface 2021 arranged at the bottom of the plate-like body to connect and transition with the inner liner bottom plate, the curved surface portion includes a second bending surface 2032 located at the top of the second concave surface and bent toward the plate-like body, and a second transition curved surface 2022 connecting the first bending surface and the second bending surface, the second bending surface 2032 is connected to the plate-like body, the first transition curved surface is connected to the second transition curved surface, and the first bending surface is connected to the inner liner bottom plate 204.

[0056] Preferably, the first concave surface includes a horizontal bending surface formed by bending the bottom of the first side panel from top to bottom toward the inside of the inner tank, a vertical bending surface formed by bending the end of the horizontal bending surface downward, and the bottom end of the vertical bending surface is bent toward the bottom plate to form the first bending surface.

[0057] Alternatively, the first concave surface includes a curved surface that is first retracted into the inner container from top to bottom from the bottom of the side plate and a vertical surface that extends vertically downward from the bottom end of the curved surface, and the bottom end of the vertical surface is bent toward the bottom plate to form the first bent surface.

[0058] Preferably, the second transition curved surface is an arc surface that bends and extends from the side of the second concave surface close to the second side plate toward the first transition curved surface of the second side plate, and the upper and lower sides of the arc surface are respectively connected to the first bending surface and the second bending surface.

[0059] Example 2

[0060] Example 2, this reference Figure 1 As shown, this embodiment further illustrates the structure of the inner pot: in this embodiment, the inner pot can be pushed in / out and is arranged in the shell or bracket of the dishwasher, including a bottom plate 204, two side plates 203 extending along the movement direction of the inner pot and arranged on both sides of the bottom plate 204, and a front plate 201 and a rear plate 202 respectively connected to the two ends of the two side plates 203. The inner pot is divided into a plurality of splicing parts, and each splicing part is spliced ​​to form the inner pot. The bottom plate 204 and the two side plates 203 are located on different splicing parts, and the two side plates 203 are provided with a concave surface 2033 concave toward the interior of the inner pot.

[0061] In the present invention, the inner liner is provided with a recessed surface 2033 for avoiding the slide rail, which is beneficial to the expansion of the inner liner. Moreover, the recessed surface 2033 is provided on the side plate 203, which has little stretching and does not affect the structural strength of the inner liner.

[0062] Preferably, the two side panels 203 are located on the same splicing component, or the two side panels 203 are respectively located on a splicing component, and the bottoms of the two side panels 203 are both recessed toward the interior of the inner container to form the recessed surface 2033 .

[0063] Preferably, the concave surface 2033 is formed by punching at the bottom of the side plate 203 facing the interior of the inner container.

[0064] See also Figure 2 and Figure 3 As shown, the concave surface includes a horizontal bending surface 20331 formed by bending the bottom of the side panel 203 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. The horizontal bending surface 20331 and the vertical bending surface 20332 are connected and transitioned by a smooth arc surface.

[0065] Preferably, a first bending surface 2031 that bends and extends toward the bottom plate 204 is provided at the bottom of the vertical bending surface 20332 , and the first bending surface 2031 is connected to the corresponding side of the bottom plate 204 .

[0066] In the above scheme, the bottom edge of the horizontal bending surface 20331 is bent toward the bottom to form the first bending surface 2031. The first bending surface 2031 is preferably in the same plane as the bottom plate 204. In this way, the joint position of the bottom plate 204 and the lower edge of the side plate 203 is on the plane, not at the corner, which facilitates the alignment of the splicing parts and moves the welding position to the plane, reducing the difficulty of welding.

[0067] Preferably, second bending surfaces 2032 are respectively provided on both sides of the side panels 203 , bending and extending toward the front panel 201 and the rear panel 202 , and the second bending surfaces 2032 are connected to the corresponding front panel 201 or the rear panel 202 .

[0068] In the above scheme, both sides of the side panel 203 are bent toward the front panel 201 and the rear panel 202 to form the second bent surface 2032. The side where the second bent surface 2032 is spliced ​​with the front panel 201 or the rear panel 202 is in the same plane as the front panel 201 or the rear panel 202, thereby avoiding the corners and facilitating welding and fixation.

[0069] In the present invention, the design of the second bending surface 2032 prevents splicing on the concave surface 2035 / 2033, and the splicing position is transferred to the plane, thereby simplifying the welding process.

[0070] See also Figure 4 and Figure 5 As shown, in another embodiment, the two side plates 203 are respectively punched with convex profiles 2034 in directions opposite to the opposite side plates 203 , and a concave surface 2035 is formed on the side plates 203 at the bottom of the profiles 2034 .

[0071] In the scheme, the concave surface 2035 is because after the side plate 203 is punched by the die 2034, the bottom of the side plate 203 is a concave surface 2035 relative to the die 2034. The convex structure is formed by punching the die 2034, and the inner space of the liner is expanded. In the scheme, the concave surface 2035 is different from the above-mentioned concave surface 2033 in that the concave surface 2035 is less curved, because the die area is large, and if the concave surface 2035 punched is too curved, it is easy to be stretched too much.

[0072] In the middle of the side plate 203, the die 2034 is punched to the outside of the liner, and a large-area convex die 2034 is formed in the middle of the side plate 203, thereby facilitating the expansion of the liner.

[0073] Preferably, the cross-sectional profile of the concave surface 2035 cut by the vertical surface perpendicular to the side plate 203 includes the first curve 20351 with the curvature center inside the liner and the second curve 20352 with the curvature center outside the liner from top to bottom, and the first curve 20351 and the second curve 20352 are smoothly transitioned.

[0074] The length of the first curve 20351 is equal to the length of the second curve 20352; the curvature of the first curve 20351 is equal to the curvature of the second curve 20352. Through the structure design, the stretching strength of the two bending parts at the edge of the die 2034, that is, the concave surface 2035, is the same, the plate material is uniformly stretched, and the thickness is uniform, thereby preventing local excessive stretching from affecting the quality of the liner.

[0075] Preferably, the bottom plate 204, the front plate 201, and the rear plate 202 form a first splicing component, and the two side plates 203 are two second splicing components, and the two side edges and the bottom edge of the side plate 203 are provided with a connecting part, and the side plate 203 is connected with the first splicing component through the connecting part.

[0076] The following provides a manufacturing method of the dishwasher liner, including the following steps:

[0077] S1, according to the size of the liner, punching / cutting the first splicing component of the liner from the plate, the first splicing component at least including the bottom plate 204 of the liner;

[0078] S2, punching and / or cutting other splicing components of the liner from the plate, the other splicing components including the side plate 203 of the liner, and the side plate 203 is punched to form a concave surface recessed to the inside of the liner;

[0079] S3, after the first splicing component and each second splicing component are spliced with each other, the top opening liner is obtained by setting the process connection.

[0080] Specifically, in step S1, a long strip of plate body is cut from the plate material, and the two sides of the plate body are bent upward to form the bottom plate 204, front plate 201 and side plate 203 of the inner liner; in step S2, two second splicing parts are punched out from the plate material, and the two splicing plate parts are the two side plates 203 of the inner liner. The side plates 203 are punched to form concave surfaces 2035 / 2033 that are concave toward the interior of the inner liner, and extended surfaces bent toward the first splicing parts are punched out on both sides and the bottom of the side plates 203. In step S3, the extended surfaces on the side plates 203 are spliced ​​and welded to the first splicing parts.

[0081] Example 3

[0082] Example 3, based on Example 2, provides a connection solution between the various splicing components of the dishwasher inner tank. Specifically, the dishwasher inner tank is divided into multiple splicing components, each splicing component is spliced ​​to form the inner tank, and two adjacent splicing components are connected by a splicing structure.

[0083] In the above solution, the dishwasher inner tank is divided into multiple 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 avoiding the plate being highly stretched, resulting in insufficient strength or even becoming waste.

[0084] See also Figure 6-8 As shown, the splicing structure includes a first connecting surface 250 provided on one of two adjacent splicing components and a second connecting surface 251 provided on the other splicing component, and the first connecting surface 250 and the second connecting surface 251 are fitted and connected.

[0085] In the above solution, the splicing structure is connected in a surface-to-surface overlapping manner, which is conducive to the splicing and positioning of each splicing component.

[0086] Preferably, among two adjacent splicing parts, one side edge of the splicing part and the other splicing part is provided with a first connecting surface 250 that bends and extends toward the outside of the inner liner, and the corresponding side edge of the other splicing part is provided with a second connecting surface 251 that bends and extends toward the outside of the inner liner, and the first connecting surface 250 and the second connecting surface 251 are fitly connected.

[0087] In the above solution, the first connecting surface 250 and the second connecting surface 251 are welded after being bonded together. The first connecting surface 250 can be obtained by bending the edge of the corresponding splicing component at a certain angle, and the second connecting surface 251 can be obtained by bending the edge of another splicing component at a certain angle. The bending angle ensures that the first connecting surface 250 and the second connecting surface 251 are parallel to each other, so that the surface-to-surface bonding can be achieved.

[0088] See also Figure 6 As shown, the first connecting surface 250 and the second connecting surface 251 are both formed by vertically bending the edges of the corresponding splicing components.

[0089] Preferably, the first connecting surface 250 and the second connecting surface 251 are welded and fixed after being attached to each other;

[0090] Preferably, the first connecting surface 250 and the second connecting surface 251 are of equal length, and both lengths are very small so as not to affect the installation space of the dishwasher inner tank. In addition, the first connecting surface 250 and the second connecting surface 251 are of equal length, and the end surface formed after welding is wide, which is not easy to cause cuts to the external structure.

[0091] See also Figure 7 As shown, in another embodiment, of two adjacent splicing components, the edge of one splicing component where it joins the other is provided with a first connecting surface 250 that bends and extends toward the exterior of the inner liner. The edge of the corresponding side of the other splicing component is provided with a second connecting surface 251 that bends and extends toward the exterior of the inner liner. The length of the second connecting surface 251 is greater than the length of the first connecting surface 250. After the first connecting surface 250 and the second connecting surface 251 are bonded together, the portion of the second connecting surface 251 that is longer than the first connecting surface 250 bends toward the other side of the first connecting surface 250, forming a three-layer bonding surface. This three-layer bonding surface bends toward and bonds to the outer surface of any splicing component. In this embodiment, a three-layer bonding surface is formed, the splicing structure is relatively stable, and there are no protruding end surfaces, which will not damage other components.

[0092] See also Figure 8 As shown, in another embodiment, among two adjacent splicing components, the edge of one side where one splicing component is spliced ​​with the other splicing component is formed with a recess toward the outside of the inner liner to form the first connecting surface 250, and the edge of the corresponding side of the other splicing component is the second connecting surface 251, and the edge of the corresponding side of the splicing component is attached to the first connecting surface 250.

[0093] In the above solution, among two adjacent splicing components, the edge of one splicing component is recessed to form the first connecting surface 250 , while the edge of the other splicing component remains unchanged and is directly overlapped on the first connecting surface 250 .

[0094] Preferably, the edge of a splicing component is first bent toward the side away from the inner liner to form a bending section 252, and the bending section 252 is bent again to form a first connecting surface 250 parallel to the edge of the other splicing component. The height of the bending section 252 in the direction perpendicular to the first connecting surface 250 matches the thickness of the second connecting surface. After the second connecting surface 251 is attached to the first connecting surface 250, the inner surfaces of the two splicing components transition smoothly, thereby making the internal structure of the inner liner flat.

[0095] The inner pot can be pushed in / out and is arranged in the shell or bracket of the dishwasher, including a bottom plate 204, two side plates 203 extending on both sides of the bottom plate 204 along the movement direction of the inner pot, and a front plate 201 and a rear plate 202 respectively connecting the two ends of the two side plates 203. The bottom plate, the front plate 201, and the rear plate 202 constitute a first splicing component, and the two side plates 203 are respectively the second splicing component and the third splicing component. The first connecting surfaces 250 are provided at the notches on both sides of the first splicing component, and the second connecting surfaces 251 are provided on both sides and the bottom edge of the two side plates 203. The first connecting surface 250 and the second connecting surface 251 are connected.

[0096] Preferably, the bottom of the two side panels 203 is provided with a first bending surface 2031 bent toward the bottom plate of the first splicing component, the edge of the first bending surface 2031 is provided with the first connecting surface 250, and the second connecting surfaces 251 are correspondingly provided on both sides of the bottom plate.

[0097] In the above scheme, the bottom of the side panel 203 is bent horizontally, and a first connecting surface 250 is set on the edge, so that the splicing point avoids the corner between the side panel 203 and the bottom panel, so that the splicing position is located on the plane, and the overlapping structure is adopted so that the two splicing parts can prevent processing errors, can be stably overlapped, and then welded and fixed.

[0098] Preferably, the two sides of the two side panels 203 are respectively provided with second bending surfaces 2032 that bend and extend toward the front panel 201 and the rear panel 202, and the edge of the second bending surface 2032 is provided with the first connecting surface 250, and the two sides of the front panel 201 and the rear panel 202 are respectively provided with the second connecting surface 251.

[0099] Similarly, the design of the above-mentioned second bending surface 2032 avoids the corner between the side panel 203 and the front panel 201 or the rear panel 202 at the splicing point, so that the splicing position is located on the plane, and the overlapping structure is adopted so that the two splicing parts can prevent processing errors, can be stably overlapped, and then welded and fixed.
