Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, and in particular to a dishwasher base frame and a dishwasher. Background Technology

[0002] With the increasing demands for cost control and production efficiency in the home appliance manufacturing industry, lightweight design of dishwasher base frames has become an important development direction for the industry. Traditional dishwasher bases mostly adopt a one-piece stamping or heavy aluminum profile splicing structure, which has problems such as high material costs, large mold investment, and complex assembly processes. Especially in the production of large dishwashers, the transportation and storage costs of the integral base are high, and the installation process requires multiple people to cooperate, making it difficult to achieve rapid on-site assembly. Although existing sheet metal welded frames can reduce some weight, it is difficult to control welding deformation, and stress concentration is prone to occur at the connection points, affecting the structural stability of long-term use.

[0003] Existing dishwasher base frames often require increased sheet metal thickness to ensure structural strength, leading to material waste. Therefore, there is an urgent need to develop a dishwasher base frame and a dishwasher itself to address the technical problems of bulky and costly base frames in existing technologies. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a base frame for a dishwasher and a dishwasher, which achieves lightweight and low cost while ensuring structural strength.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A dishwasher base frame includes multiple sheet metal parts and multiple corner brackets; the multiple sheet metal parts and multiple corner brackets are connected alternately in sequence to form a ring structure, the ring structure being used to support the inner tub of the dishwasher.

[0007] Furthermore, the corner bracket is installed on the corresponding sheet metal part by injection molding.

[0008] Furthermore, the corner bracket is connected to the sheet metal part via a snap-fit ​​structure.

[0009] Furthermore, the snap-fit ​​structure includes a snap-fit ​​groove provided on the sheet metal part, and a snap-fit ​​part provided on the corner bracket; the snap-fit ​​groove includes a slot and a locking groove, and the slot and the locking groove belonging to the same snap-fit ​​groove are interconnected; the snap-fit ​​part slides into the slot and then snaps into the locking groove.

[0010] Furthermore, both ends of the sheet metal part are connecting ends; the buckle structure includes multiple snap-fit ​​grooves and multiple snap-fit ​​parts; each connecting end is provided with at least two snap-fit ​​grooves, and multiple snap-fit ​​parts are provided on the corner brackets, and the snap-fit ​​parts on each corner bracket are snapped into the corresponding snap-fit ​​grooves on two adjacent sheet metal parts; the sheet metal part has an inner liner support part, which is used to connect the inner liner support piece.

[0011] Furthermore, the inner liner support is located between the two snap-fit ​​grooves at the same connecting end.

[0012] Furthermore, the inner liner support is located between two snap-fit ​​grooves that are spaced apart in the horizontal direction at the same connecting end.

[0013] Furthermore, the corner bracket is a component made of plastic.

[0014] A dishwasher, wherein the inner tub support portion is connected to the inner tub support piece, and the inner tub support piece is connected to a fastener; the inner tub support portion is provided with a fastening portion; the fastener passes through the fastening portion and the corner bracket.

[0015] Furthermore, the inner liner support plate, the sheet metal parts, and the corner brackets are arranged in a sequentially stacked manner from the outside of the dishwasher to the inside of the dishwasher.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. Based on a ring-shaped frame structure formed by the alternating connection of multiple sheet metal parts and corner brackets, the sheet metal parts provide structural strength as the main load-bearing components, while the corner brackets serve as connecting nodes to achieve rapid assembly and positioning. This significantly reduces material usage and component weight while ensuring overall load-bearing performance. Utilizing the stress characteristics of the closed ring structure, the load on the inner liner is evenly distributed across the entire perimeter of the base, avoiding localized stress concentration and improving structural stability and overall rigidity. The modular combination of sheet metal parts and corner brackets simplifies structural composition and assembly processes, reducing mold costs and manufacturing complexity. This base frame achieves structural lightweighting and optimized manufacturing costs while ensuring reliable support.

[0018] 2. Based on the corner bracket, it is installed on the sheet metal part by injection molding, which realizes a stable covering connection between the two, effectively enhances the structural strength and integrity of the connection node, and improves the assembly efficiency and consistency of the base frame.

[0019] 3. The corner brackets and sheet metal parts are connected via a snap-fit ​​structure, enabling rapid assembly and reliable locking of the base frame, significantly improving assembly efficiency. The insertion, sliding, and locking mechanisms of the snap-fit ​​grooves and buckles ensure a smoother connection process with a clear sense of proper assembly, effectively preventing loosening during use. Multiple snap-fit ​​grooves at both ends of the sheet metal parts interlock with the corner brackets, enhancing the strength and stability of the joint connections and ensuring the overall structural stability of the frame. The layout of the inner liner support between the snap-fit ​​grooves at the connection ends optimizes the load-bearing path, allowing the load on the inner liner to be transferred more effectively to the main frame. This snap-fit ​​connection scheme ensures structural strength while achieving convenient assembly of the base frame and improved overall rigidity. Attached Figure Description

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] See Figures 1-3 The following is a detailed description of a preferred embodiment of this utility model:

[0028] A dishwasher base frame includes multiple sheet metal parts 100 and multiple corner brackets 200; the multiple sheet metal parts 100 and multiple corner brackets 200 are sequentially and alternately connected to form a ring structure, which supports the dishwasher's inner tub. The core function of this base frame is to provide reliable foundation support for the dishwasher's inner tub by forming a stable ring support structure through the alternating connection of multiple sheet metal parts 100 and corner brackets 200.

[0029] The frame is primarily composed of multiple sheet metal parts 100 and multiple corner brackets 200. These sheet metal parts 100 and corner brackets 200 are arranged alternately in space and fixed to each other through connecting nodes, ultimately forming a closed ring structure. The upper surface of this ring structure is configured to directly support and install the dishwasher's inner tub.

[0030] During load-bearing and stress-bearing processes, the load of the inner liner and its contents is initially applied to the annular structure. Subsequently, this load is transmitted through the sheet metal 100, which serves as the main load-bearing component, and the force is distributed and transferred at each connection node by the corner brackets 200. Ultimately, the load is distributed across the entire annular frame, forming a complete closed loop of force flow, thereby effectively avoiding stress concentration and ensuring the stability of the support.

[0031] Furthermore, during the assembly process, the sequential and alternating connections are not limited to forming a closed loop at both ends. Corner brackets 200 can serve as core connection nodes, connecting with sheet metal parts 100 from different directions. For example, one corner bracket 200 can simultaneously connect sheet metal parts 100 from three directions, forming a T-shaped node. The middle of the frame can also be reinforced and extended through such nodes. The corner bracket 200 itself can also be designed with outwardly protruding mounting parts for connecting other components of the dishwasher. To enhance the structural stability of the connection between the corner bracket 200 and the sheet metal part 100, auxiliary fixing structures can be added between them. For example, set screws can be used for radial locking, or elastic barbs and positioning holes can be used for secondary locking. Guide ribs can also be designed on the corner bracket 200, and corresponding limiting grooves can be stamped on the sheet metal part 100 to achieve pre-positioning and error prevention in the initial stage of assembly, thereby improving the rigidity and reliability of the connection node.

[0032] In practice, first prepare a specified number of sheet metal parts 100 and corner brackets 200. Then, connect one end of one sheet metal part 100 to one corner bracket 200, and then connect another sheet metal part 100 to the other side of the corner bracket 200, repeating this process alternately. Finally, connect the components at both ends to form a complete ring frame, onto which the dishwasher's inner tub can be installed and fixed.

[0033] It is understandable that the ring-shaped frame structure, formed by the alternating connection of multiple sheet metal parts 100 and corner brackets 200, utilizes the sheet metal parts 100 as the main load-bearing components to provide structural strength, and the corner brackets 200 as connecting nodes to achieve rapid assembly and positioning. This significantly reduces material usage and component weight while ensuring overall load-bearing performance. Based on the stress characteristics of the ring-shaped closed structure, the load of the inner liner is evenly distributed to the entire perimeter of the base, avoiding local stress concentration and improving structural stability and overall rigidity. The modular combination of sheet metal parts 100 and corner brackets 200 simplifies structural composition and assembly processes, reducing mold costs and manufacturing complexity. This base frame achieves structural lightweighting and optimized manufacturing costs while ensuring reliable support.

[0034] Preferably, the corner bracket 200 is installed on the corresponding sheet metal part 100 by injection molding. The core function of this embodiment is to integrate the corner bracket 200 and the sheet metal part 100 into one unit through the injection molding process, thereby enhancing the strength and integrity of the connection point.

[0035] Structurally, the corner bracket 200 is directly wrapped around the outer end of the sheet metal part 100 by injection molding. The injection molding material solidifies around the pre-set connection area of ​​the sheet metal part 100 to form a tightly wrapped corner bracket 200 component, so that the metal sheet metal part 100 and the plastic corner bracket 200 can be firmly fitted at the contact interface.

[0036] During assembly and load-bearing, the integrated structure uses the mechanical interlocking force generated by injection molding to firmly fix the corner bracket 200 to the sheet metal part 100. When the frame is under stress, the load acting on the corner bracket 200 is effectively transferred to the sheet metal part 100 through the large-area covered contact surface, avoiding stress concentration and thus significantly improving the reliability of the connection nodes and the structural stability of the overall frame.

[0037] It is understandable that the corner bracket 200 is installed on the sheet metal part 100 by injection molding, which achieves a stable wrapping connection between the two, effectively enhancing the structural strength and integrity of the connection node, while improving the assembly efficiency and consistency of the base frame.

[0038] Preferably, the corner bracket 200 and the sheet metal part 100 are connected by a snap-fit ​​structure. The core function of this embodiment is to achieve quick connection and reliable locking between the corner bracket 200 and the sheet metal part 100 through the snap-fit ​​structure, thereby significantly improving the assembly efficiency and structural stability of the base frame.

[0039] The snap-fit ​​structure mainly consists of two parts: a snap-fit ​​groove 300 on the sheet metal part 100 and a snap-fit ​​part 400 on the corner bracket 200. The snap-fit ​​groove 300 further includes a slot 301 and a locking groove 302 that are interconnected. Both ends of the sheet metal part 100 form a connecting end 500, and each connecting end 500 is provided with at least two snap-fit ​​grooves 300; the corner bracket 200 is provided with a plurality of snap-fit ​​parts 400 that correspond one-to-one, so that one corner bracket 200 can simultaneously snap-fit ​​with the ends of two adjacent sheet metal parts 100.

[0040] During assembly, the operator aligns the latching part 400 on the corner bracket 200 with the slot 301 on the connecting end 500 of the sheet metal part 100 and inserts it. Then, the operator pushes the corner bracket 200 along the frame plane, causing the latching part 400 to slide from the slot 301 into the locking groove 302 that communicates with it. During this sliding process, the latching part 400 undergoes elastic deformation. When it is fully inserted into the locking groove 302, the latching part 400 springs back, producing a clear sense of engagement and achieving mechanical locking, effectively preventing the connection point from loosening during subsequent use. This process can be completed without tools, achieving rapid assembly.

[0041] In addition to the snap-fit ​​structure, other connection methods can be used between the corner bracket 200 and the sheet metal part 100 to achieve quick assembly and reliable fixation. For example, a screw fastening structure can be used, by providing threaded holes on the corner bracket 200 and through holes on the sheet metal part 100, and using self-tapping screws or machine screws for locking, to achieve a detachable and secure connection. Alternatively, a flexible pin structure can be used, by pressing the pin on the corner bracket 200 into the corresponding pin hole on the sheet metal part 100, utilizing the elastic deformation and rebound of the pin to achieve locking. Furthermore, it can be designed as a hook and slot combination, where the hook of the corner bracket 200 is hooked into the slot of the sheet metal part 100 from top to bottom or horizontally, achieving quick attachment and positioning.

[0042] Preferably, the snap-fit ​​structure includes a snap-fit ​​groove 300 on the sheet metal part 100 and a snap-fit ​​portion 400 on the corner bracket 200; the snap-fit ​​groove 300 includes a slot 301 and a locking groove 302, and the slot 301 and the locking groove 302 belonging to the same snap-fit ​​groove 300 are interconnected; the snap-fit ​​portion 400 slides into the slot 301 and then snaps into the locking groove 302. The core function of this embodiment is that, through the cooperation of the slot 301 and the locking groove 302, a clear assembly path and a reliable locking position are provided for the snap-fit ​​connection.

[0043] Structurally, the snap-fit ​​structure includes a snap-fit ​​groove 300 on the sheet metal part 100 and a snap-fit ​​part 400 on the corner bracket 200. The snap-fit ​​groove 300 is composed of a slot 301 and a locking groove 302 that are interconnected.

[0044] During assembly, the latching part 400 of the corner bracket 200 first aligns with and enters the slot 301 of the sheet metal part 100, and then slides along the connecting path into the locking groove 302. The latching part 400 is positioned in the locking groove 302, completing the locking and achieving a stable connection between the two.

[0045] Preferably, both ends of the sheet metal part 100 are connecting ends 500; the snap-fit ​​structure includes multiple snap-fit ​​grooves 300 and multiple snap-fit ​​parts 400; each connecting end 500 is provided with at least two snap-fit ​​grooves 300, and multiple snap-fit ​​parts 400 are provided on corner brackets 200, with the snap-fit ​​parts 400 on each corner bracket 200 engaging with the corresponding snap-fit ​​grooves 300 on two adjacent sheet metal parts 100; the sheet metal part 100 has an inner liner support part 600, which is used to connect the inner liner support piece. The core function of this embodiment is that, through the coordinated design of multiple sets of snap-fits and the inner liner support part 600, the frame can be quickly assembled while providing direct and stable support for the inner liner.

[0046] Both ends of the sheet metal part 100 are defined as connecting ends 500, and each connecting end 500 is provided with at least two snap-fit ​​grooves 300; the corner bracket 200 is provided with multiple matching snap-fit ​​parts 400. One corner bracket 200 engages with the snap-fit ​​grooves 300 on the ends of two adjacent sheet metal parts 100 simultaneously through its snap-fit ​​parts 400. In addition, an inner liner support part 600 is also formed on the sheet metal part 100.

[0047] The corner bracket 200 serves as the core connector, with its two side latches 400 engaging with the corresponding latching slots 300 on the connecting ends 500 of adjacent sheet metal parts 100, thereby connecting multiple sheet metal parts 100 into an overall frame. After assembly, the inner liner support plate is fixed to the inner liner support part 600, directly supporting the upper inner liner and effectively transferring the load to the main body of the sheet metal part 100.

[0048] Preferably, the inner liner support portion 600 is located between two snap-fit ​​grooves 300 on the same connecting end 500. The core function of this embodiment is that by placing the inner liner support portion 600 between two snap-fit ​​grooves 300, the load-bearing structure is optimized, making the support more stable.

[0049] The inner liner support 600 is directly formed on the connecting end 500 of the sheet metal part 100, and its position is located between the two snap-fit ​​grooves 300 provided on the connecting end 500.

[0050] When the load on the inner liner is applied to the inner liner support part 600 through the inner liner support plate, the force is directly transmitted to the sheet metal part 100 solid structure between the two snap-fit ​​grooves 300, and effectively distributed to the corner bracket 200 and the entire frame through the snap-fit ​​nodes on both sides, avoiding excessive local stress and improving the reliability of the support.

[0051] Preferably, the inner liner support portion 600 is located between two horizontally spaced snap-fit ​​grooves 300 on the same connecting end 500. The core function of this embodiment is that by horizontally positioning the inner liner support portion 600 between the two snap-fit ​​grooves 300, the structural width of the connecting end 500 is effectively utilized, thereby improving the stability of the support.

[0052] Structurally, the inner liner support 600 is disposed on the same connecting end 500 of the sheet metal part 100, and its position is between two snap-fit ​​grooves 300 that are distributed horizontally at intervals on the connecting end 500.

[0053] When the load of the inner liner is applied to the inner liner support 600, the force is evenly transmitted to the entire base frame through the horizontally distributed snap-fit ​​grooves 300 on both sides and the corner brackets 200 connected to them, forming a stable horizontal force flow path, which effectively enhances the bending and torsional resistance of the support point.

[0054] Preferably, the corner bracket 200 is a component made of plastic. By using plastic to manufacture the corner bracket 200, the connection function is guaranteed while the component is lightweight and low-cost.

[0055] Corner bracket 200 is a component made of plastic through injection molding.

[0056] The plastic corner bracket 200 utilizes the elasticity of its material to undergo moderate deformation during the snap-fit ​​connection process to achieve assembly and locking. At the same time, its light weight helps to reduce the overall weight of the frame, and it has good insulation and corrosion resistance.

[0057] In addition to plastic, corner bracket 200 can also be made of other non-metallic materials. For example, fiber-reinforced composite materials, such as carbon fiber or glass fiber composites, can be used to obtain higher specific strength and stiffness; engineering ceramics or special rubbers can also be used to meet specific requirements such as high temperature resistance, wear resistance or high damping and high sealing performance in extreme environments.

[0058] Preferably, a dishwasher includes a base frame and an inner tub support plate; the inner tub support portion 600 is connected to the inner tub support plate, and the inner tub support plate is connected to fasteners; the inner tub support portion 600 is provided with a fastening part; the fasteners pass through the fastening part and the corner bracket 200. The core function of this embodiment is that the inner tub support plate, the sheet metal part 100, and the corner bracket 200 are connected as a whole by fasteners, which greatly enhances the integrity and load-bearing capacity of the connection node.

[0059] The inner liner support part 600 is provided with a fastening part; the inner liner support piece is installed on the inner liner support part 600, and the three are locked in series by a fastener passing through the inner liner support piece, the fastening part and the internal corner bracket 200 in sequence.

[0060] After the fasteners are tightened, the inner liner support plate, sheet metal part 100, and corner bracket 200 are compressed into a single composite structure. When the load of the inner liner is applied to the support plate, the load is simultaneously transmitted to the sheet metal part 100 and corner bracket 200 through the fastening force generated by the fasteners, realizing multi-path load distribution and significantly improving the connection strength and reliability of the local structure.

[0061] Preferably, the inner liner support plate, sheet metal part 100, and corner bracket 200 are arranged in a stacked manner from the outside of the dishwasher to the inside. The core function of this embodiment is that, through the stacked arrangement from the outside to the inside, the inner liner support plate is located on the outermost side, which greatly facilitates its assembly, disassembly, and maintenance.

[0062] The positional relationship between the inner tub support plate, sheet metal part 100 and corner bracket 200 is as follows: from the outside of the dishwasher towards the inside, the order is inner tub support plate, sheet metal part 100 and corner bracket 200.

[0063] During installation or removal, operators can directly access the inner drum support plates and their fasteners from the outside of the dishwasher without first removing corner brackets 200 or other internal components. This layout makes the installation, adjustment, or replacement of the support plates more direct and convenient, simplifying the maintenance process.

[0064] Understandably, the snap-fit ​​connection between the corner brackets and sheet metal parts enables rapid assembly and reliable locking of the base frame, significantly improving assembly efficiency. The insertion, sliding, and locking mechanisms of the snap-fit ​​grooves and buckles ensure a smoother connection process with a clear sense of proper assembly, effectively preventing loosening during use. Multiple snap-fit ​​grooves at both ends of the sheet metal parts interlock with the corner brackets, enhancing the strength and stability of the joint connections and ensuring the overall structural stability of the frame. The layout of the inner liner support between the snap-fit ​​grooves at the connection ends optimizes the load-bearing path, allowing the load on the inner liner to be transferred more effectively to the main frame body. This snap-fit ​​connection scheme, while ensuring structural strength, achieves convenient assembly of the base frame and improves overall rigidity.

[0065] In summary, the dishwasher base frame is formed by alternating connections of multiple sheet metal parts 100 and corner brackets 200 to create a ring structure. Sheet metal parts 100 serve as the main load-bearing components, providing overall strength, while corner brackets 200 act as connecting nodes for rapid assembly and positioning. This design reduces weight and cost while maintaining load-bearing capacity. Based on the stress characteristics of the closed ring structure, the load on the inner tub is evenly distributed across the entire perimeter of the base, preventing stress concentration and improving structural stability and overall rigidity. Furthermore, corner brackets 200 can be injection molded onto sheet metal parts 100 to enhance the strength and integrity of the connecting nodes, improving assembly efficiency and consistency; or they can be fastened and reliably locked using a snap-fit ​​structure. The insertion, sliding, and locking mechanisms of the snap-fit ​​grooves 300 and snap-fit ​​parts 400 ensure a smooth assembly process with a sense of secure fit, effectively preventing loosening. Multiple snap-fit ​​grooves 300 at both ends of the sheet metal parts 100 interlock with the snap-fit ​​parts 400 of the corner brackets 200, further enhancing node strength and overall frame stability. This base frame achieves lightweight and low cost while also ensuring load-bearing reliability and ease of assembly.
