Description

Technical Field

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

[0002] Dishwashers are appliances that automatically wash tableware, including bowls, chopsticks, plates, dishes, knives, and forks. Commercially available household dishwashers include cabinet-type, countertop-type, and sink-integrated models. However, these often take up a significant amount of kitchen space, creating inconvenience for users. Drawer-type dishwashers are now available on the market. These dishwashers are placed within a housing or bracket that can be pushed in and out. Existing drawer-type dishwashers have a regular, cubical structure and have not been improved or designed to accommodate larger sizes.

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

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a dishwasher inner tank, thereby increasing the capacity of the inner tank and achieving capacity expansion of the inner tank.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0006] A dishwasher inner container comprises a bottom plate and a side plate assembly arranged on the bottom plate and surrounding the bottom plate to form a side wall of the inner container. The side plate assembly is configured as a convex structure protruding from the inside of the inner container to the outside.

[0007] In the above solution, the inner liner 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 realizing the expansion of the inner liner.

[0008] Preferably, the inner pot is slidably arranged in the shell or bracket of the dishwasher, and the side panel assembly includes two side panels extending along the sliding direction of the inner pot, and the two side panels are both configured as convex structures protruding in the direction away from the opposite side panel.

[0009] In the above solution, the two side panels are relatively arranged to form an outward convex structure, 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.

[0010] Preferably, the inner container includes a front plate and a rear plate respectively connected to both ends of the two side plates, the middle portion of the side plates 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.

[0011] In the above solution, the configuration of the side panels is obtained by stamping and forming a large area in the middle of the side panels, forming a structure with a protruding middle and retracted sides, thereby increasing the internal space of the liner.

[0012] Preferably, the side panels are respectively provided with first extension surfaces bent toward the front panel and the rear panel along the sliding direction of the inner liner to connect the front panel and the rear panel respectively. The middle portion of the side panels is a planar structure, and the two sides of the planar structure are respectively smoothly connected to the first extension surfaces of the corresponding sides through the first arc surface.

[0013] In the above solution, the center portion of the side panel is stamped into a convex flat surface, with the curved surface transitioning to the side edge of the side panel. This reduces the stamping strength of the side panel, resulting in a high-strength, high-quality liner. The smooth transition also creates a high-gloss, aesthetically pleasing liner. The design on the first extended surface shifts the seam from the corner between the side panel and the front and rear panels to the plane of the front or rear panel, simplifying the connection between the side panels and the front and rear panels.

[0014] Preferably, the middle portion of the side panel protrudes outward, and the upper and lower sides of the side panel are respectively bent and recovered toward the inner side of the inner container.

[0015] Preferably, a second extension surface is provided on the bottom edge of the side panel and is bent and extended toward the bottom panel. The middle portion of the side panel is smoothly connected to the second extension surface via a recessed surface, and the recessed surface is used for mounting the slide rails of the dishwasher.

[0016] In the above solution, the inner tank is formed with a recessed surface for mounting the dishwasher rails, thereby making full use of the space inside the dishwasher housing and facilitating the expansion of the inner tank.

[0017] Preferably, the concave surface includes a concave surface that gradually indents into the inner liner from top to bottom and a vertical surface extending downward from the end of the concave surface, and the cross-sectional profile of the concave surface longitudinally cut through the vertical surface perpendicular to the side plate on which the concave surface is located includes, from top to bottom, a first curve with a center of curvature inside the inner liner and a second curve with a center of curvature outside the inner liner, and the first curve and the second curve have a smooth transition;

[0018] Preferably, the length of the first curve is equal to the length of the second curve;

[0019] More preferably, the curvature of the first curve is equal to the curvature of the second curve.

[0020] In another structure, the concave surface includes a horizontal bending surface formed by bending the bottom wall of the side panel from top to bottom toward the inside of the inner liner, and a vertical bending surface formed by bending the end of the horizontal bending surface vertically downward. The horizontal bending surface and the vertical bending surface are connected and transitioned by a smooth arc surface.

[0021] In the above solution, the cooperation between the horizontal bending surface and the vertical bending surface is more conducive to the installation of the slide rail.

[0022] Preferably, the side panel has an upper edge portion protruding toward the inner liner axis, and the middle portion of the side panel smoothly transitions to the upper edge portion through a third curved surface, and the third curved surface gradually narrows toward the inner liner axis from bottom to top and connects to the upper edge portion.

[0023] The third curved surface gradually narrows toward the axis of the inner liner from bottom to top to form a blocking structure for blocking water flow.

[0024] In the above solution, the inner liner is stamped to form a blocking structure on the top of the side panel, and an avoidance structure for installing the guide rail is formed at the bottom of the side panel. One convex pressing realizes multiple structural functions.

[0025] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0026] The inner tank of the dishwasher of the present invention comprises a bottom plate and a side panel assembly arranged on the bottom plate and surrounding the bottom plate to form a side wall of the inner tank. The side panel assembly is configured as a convex structure protruding from the interior of the inner tank to the outside. The inner tank of the present invention is configured as a convex structure protruding from the interior of the inner tank to the outside, which increases the capacity of the inner tank and realizes the expansion of the inner tank. The convex structure is formed by stamping. After stamping, a concave surface is formed on the bottom of the inner tank, which is concave toward the interior of the inner tank. The concave surface is used to install the slide rail of the inner tank, thereby making full use of the internal space of the dishwasher bracket or the shell, which is conducive to making the inner tank larger and further realizing the expansion of the inner tank.

[0048] It should be noted that these drawings and textual descriptions are not intended to limit the conceptual scope of the present invention in any way, but rather to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0049] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0050] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0051] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0052] Example 1

[0053] See alsoFigures 1-5 As shown, this embodiment provides a dishwasher inner tank, including a bottom plate 204 and a side plate assembly arranged on the bottom plate 204 and surrounding the bottom plate to form the side wall of the inner tank. The side plate assembly is configured as a convex structure protruding from the inside of the inner tank to the outside.

[0054] In the above solution, the inner liner 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 realizing the expansion of the inner liner.

[0055] Preferably, the inner pot is slidably arranged in the shell or bracket of the dishwasher, and the side panel assembly includes two side panels extending along the sliding direction of the inner pot, and the two side panels are both configured as convex structures protruding in the direction away from the opposite side panel.

[0056] In the above solution, the two side panels are relatively arranged to form an outward convex structure, 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.

[0057] Preferably, the inner container includes a front plate and a rear plate respectively connected to both ends of the two side plates, the middle portion of the side plates 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.

[0058] In the above solution, the side panels are formed by stamping a large area in the middle of the side panels, creating a structure with a convex center and a retracted periphery, thereby increasing the internal volume of the liner. Specifically, a convex protrusion 2034 is stamped on the side panels in a direction opposite to the opposite side panels, forming a shell structure with a convex bottom wall and a peripheral wall extending toward the opposite side panel. In this method, stamping a large area in the middle of the side panels increases the internal volume of the liner.

[0059] Preferably, the side panels are provided with first extension surfaces 2032 on both sides along the sliding direction of the inner container, which are bent toward the front and rear panels to connect them respectively. The middle portion of the side panels is a planar structure, and the two sides of the planar structure are smoothly connected to the first extension surfaces 2032 on the corresponding sides via first curved surfaces 207. The middle portion of the side panels is stamped to form a convex plane, and the curved surface transitions to the side edge of the side panels. This reduces the stamping strength of the side panels, resulting in a high-strength and high-quality inner container. The smooth transition also provides a good overall gloss and an attractive appearance. The design on the first extension surface shifts the joint location from the corner between the side panels and the front and rear panels to the plane of the front or rear panel, simplifying the connection between the side panels and the front and rear panels.

[0060] The middle portion of the side panel is flat, and along the sliding direction of the inner container, the flat surface transitions to the edge of the side panel via smooth first curved surfaces 207 on both sides. This makes the side panel's central curved surface transition to the side edge of the side panel less stressful on the side panel, resulting in a strong and high-quality inner container. The smooth transition also creates a high overall gloss and beautiful appearance for the inner container.

[0061] In this embodiment, the inner container has a drawer structure and includes a front panel 201 and a rear panel 202, respectively connected to the ends of two side panels 203. First extension surfaces 2032 are provided on either side of the side panels, each extending and bending toward the front and rear panels. The first extension surfaces are connected to the corresponding front and rear panels, and the bottom wall of the inner container is connected to the first extension surfaces 2032 via the smooth first curved surface 207. The design on the first extension surfaces shifts the joint location from the corner between the side panels and the front and rear panels to the plane of the front or rear panel, simplifying the connection between the side panels and the front and rear panels.

[0062] 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 is formed at the bottom of the side panel, which is concave toward the interior of the inner tank. The concave surface 2035 is used to avoid the slide rail of the dishwasher.

[0063] In the above solution, the inner tank is formed with a recessed surface for mounting the dishwasher rails, thereby making full use of the space inside the dishwasher housing and facilitating the expansion of the inner tank.

[0064] Preferably, the concave surface includes a concave surface that gradually indents into the inner liner from top to bottom and a vertical surface extending downward from the end of the concave surface. The cross-sectional profile of the concave surface, which is longitudinally cut through a vertical surface perpendicular to the side panel on which it is located, includes, from top to bottom, a first curve 20351 with a center of curvature inside the inner liner and a second curve 20352 with a center of curvature outside the inner liner. The first curve and the second curve transition smoothly. Preferably, the length of the first curve is equal to the length of the second curve. More preferably, the curvature of the first curve is equal to the curvature of the second curve. With this structural design, the edges of the convex profile, or the two bends of the concave surface 2035, have 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.

[0065] See also Figure 5 and Figure 6 As shown, in another structure, the concave surface is a concave surface directly punched from the bottom of the side panel toward the interior of the inner container. The concave surface includes a horizontal bending surface 20331 formed by bending the bottom wall of the side panel from top to bottom toward the interior of the inner container, and a vertical bending surface 20332 formed by bending the end of the horizontal bending surface 20331 vertically downward. The horizontal bending surface and the vertical bending surface are connected and transitioned by a smooth arc surface. This structure is similar to Figure 4 The structure is different, Figure Four The reason is that the convex pressing of the stamping indirectly forms a concave surface. Because the pressing profile is large, the stamping strength cannot be high, so it has no horizontal bending surface. Figure 6Because the concave surface is directly stamped, the stamping area is small, and a concave surface with a horizontal bending surface and a vertical bending surface can be stamped out. In this solution, the cooperation of the horizontal bending surface and the vertical bending surface is more conducive to the installation of the slide rail.

[0066] Preferably, the bottom edge of the side panel is provided with a second extension surface 2031 that bends and extends toward the bottom panel, and the recessed surface smoothly transitions to the second extension surface 2031. The second extension surface is connected to the bottom panel 204 of the inner container.

[0067] See also Figure 7 As shown, the bottom wall of the side panel is connected to the top edge of the side panel via a third curved surface 800, and the third curved surface 800 gradually narrows toward the axis of the inner tank from bottom to top to form a blocking structure for blocking water flow.

[0068] In the above solution, the inner liner is stamped to form a blocking structure on the top of the side panel, and an avoidance structure for installing the guide rail is formed at the bottom of the side panel. An outward convex press 2034 realizes multiple structural functions.

[0069] Furthermore, the front plate and / or rear plate of the inner container are similar to the two side plates and are configured to bulge outwards toward the inner container, thereby expanding the inner container.

[0070] Example 2

[0071] This second embodiment provides an inner liner structure based on the first embodiment, specifically:

[0072] See this Figure 1 and Figure 2 As shown, 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 inner pot is divided into multiple 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. The two side plates 203 are provided with a concave surface 2033 concave toward the interior of the inner pot.

[0073] In the present invention, the inner liner is provided with a recessed surface 2033 / 2035 for avoiding the slide rail, which is beneficial to the expansion of the inner liner. In addition, 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.

[0074] 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 surfaces 2033 / 2035.

[0075] See also Figure 3 andFigure 4 As shown, the two side plates 203 are respectively punched with an outward convex outward convex stamping 2034 in a direction opposite to the side plate 203 on the opposite side, and a concave surface 2035 is formed on the side plate 203 at the bottom of the outward convex stamping 2034.

[0076] In this scheme, the concave surface 2035 is because after the side plate 203 is punched with the outward convex stamping 2034, the bottom of the side plate 203 is a concave surface 2035 relative to the outward convex stamping 2034. By punching the outward convex stamping 2034, an outward convex structure is formed, which expands the inner space of the inner container. In this 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 area of the outward convex stamping is large, and if the concave surface 2035 punched is too curved, it is easy to be stretched too much.

[0077] In the middle of the side plate 203, an outward convex stamping 2034 is punched towards the outside of the inner container, so that a large area of outward convex stamping 2034 is formed in the middle of the side plate 203, thereby facilitating the expansion of the inner container.

[0078] 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 respectively a second splicing component and a third splicing component, and the two side plates 203 are provided with a connecting part on the two side edges and the bottom edge, and the side plate 203 is connected with the first splicing component through the connecting part.

[0079] The following provides a manufacturing method of the dishwasher inner container, comprising the following steps:

[0080] S1, according to the size of the inner container, punching / cutting the first splicing component of the inner container from the plate, and the first splicing component at least includes the bottom plate 204 of the inner container;

[0081] S2, punching and / or cutting other splicing components of the inner container from the plate, and the other splicing components include the side plate 203 of the inner container, and the side plate 203 is punched to form a concave surface 2035 / 2033 which is concave to the inside of the inner container;

[0082] S3, after the first splicing component and each second splicing component are spliced with each other, the top opening inner container is obtained through the setting process connection.

[0083] Specifically, in step S1, a long strip-shaped plate body is cut from the plate, and the two sides of the plate body are respectively bent upwards to form the bottom plate 204, the front plate 201 and the side plate 203 of the inner container; in step S2, the second splicing component and the third splicing component are punched from the plate, and the two splicing components are the two side plates 203 of the inner container, the side plate 203 is punched to form a concave surface 2035 / 2033 which is concave to the inside of the inner container, and the two sides and the bottom of the side plate 203 are punched to form an extension surface which is bent to the first splicing component; in step S3, the extension surface on the side plate 203 is spliced and welded with the first splicing component.

[0084] Example 3

[0085] In Example 3, see Figure 2 As shown, the dishwasher side panel has a convex protrusion 2034 formed by punching toward the outside of the inner container. The bottom of the convex protrusion on the side panel is punched toward the inside of the inner container to form the concave surface 2033, thus forming a double-step surface structure at the bottom of the side panel. In this solution, considering that the convex protrusion cannot be punched too large due to strength reasons, the convex protrusion 2034 is punched first, resulting in a small bottom depression that is insufficient for installing the slide rail. Then, the concave surface 2033 is punched at the bottom of the side panel toward the axis of the inner container. The concave surface is punched at different positions on both sides of the side panel to form the said concave surface, avoiding the high tensile strength of the inner container caused by a single forming operation, which may easily damage the inner container or reduce its quality. The double punching of the side panel ensures that the installation space formed at the concave surface is sufficient for installing the slide rail.

[0086] Example 4

[0087] In the fourth embodiment, the inner tank of the dishwasher is formed by splicing a plurality of splicing parts. Specifically, the inner tank of the dishwasher is divided into a plurality of splicing parts, each splicing part is spliced ​​to form the inner tank, and two adjacent splicing parts are connected by a splicing structure.

[0088] 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.

[0089] See also Figures 8-10 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.

[0090] In the above solution, the splicing structure is connected in a surface-to-surface fitting manner, which is beneficial to the splicing positioning of each splicing component.

[0091] 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.

[0092] 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.

[0093] See also Figure 8 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.

[0094] Preferably, the first connecting surface 250 and the second connecting surface 251 are welded and fixed after being attached to each other;

[0095] 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.

[0096] See also Figure 9 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.

[0097] See also Figure 10 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.

[0098] 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 connected to the first connecting surface 250 .

[0099] 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.

[0100] 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 outer panel 302 body is used to cover the outer side of the inner liner body 200 and serve a decorative purpose. The connecting flange is used to connect the outer panel 302 and the inner liner body 200. The present invention adopts a structure in which the second splicing component 102 and the outer panel 302 body are integrally formed. When connecting the inner liner body 200 and the outer panel 302, the connection between the intermediate connecting structure and the outer panel 302 is reduced, thereby reducing the number of welding steps.

[0143] Example 8

[0144] This embodiment provides another structure of the inner liner, such as Figure 16 As shown, it includes a bottom wall (bottom plate) and side walls (including a front plate, a rear plate and two side plates), and the side walls include a first splicing portion 2012 and a second splicing portion 2013. After the first splicing portion 2012 and the second splicing portion 2013 are spliced ​​together, the side walls are formed. 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 ​​together.

The first side and / or the second side are provided with a notch, and 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. The notch forms an installation port 2011 for placing a detergent adding device when spliced, and the size of the notch can be set to different sizes and shapes according to the size of the detergent adding device.

[0146] For example, a notch can be opened on the first side of the first splicing surface, and a notch can be opened at the corresponding position of the second side. When the first splicing surface and the second splicing surface are spliced ​​together, the middle notch portion of the first side and the middle notch portion of the second side form an installation port 2011 for placing a detergent adding device.

[0147] As an alternative to the above-mentioned solution, 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.

[0148] In this embodiment, an installation port 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 steps but also saves costs.

[0149] Furthermore, a fixing plate is provided at the installation opening 2011 , and the fixing plate is located outside the inner tank body. The detergent adding device is fixedly connected to the fixing plate by screws, and is thereby fixed to the inner tank body.

[0151] In this embodiment, the side wall is formed by bending and splicing at least one rectangular stainless steel sheet, with one end of the sheet forming a first splicing surface and the other end forming a second splicing surface. The side wall can also be formed by bending and splicing two or more stainless steel sheets. This embodiment uses a single bent stainless steel sheet as an example.

[0152] Specifically, the rectangular plate is bent four times to form the side wall of the inner liner, and the first splicing surface and the second splicing surface at both ends of the plate are spliced ​​to form the front wall of the inner liner. The splicing seam 2014 is located on the front wall surface of the inner liner. In this embodiment, the splicing seam 2014 of the side wall of the inner liner is located on a plane, which avoids special-shaped welding, reduces the difficulty of welding, and effectively prevents the problem of cracking easily caused by stretching of the stainless steel inner liner.
