Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, and more particularly to a dishwasher. Background Technology

[0002] As a household appliance for cleaning dishes, dishwashers can automatically clean dishes, freeing up your hands and saving water and being environmentally friendly. They are being accepted and recognized by more and more users.

[0003] In existing technologies, the inner tub of a dishwasher is usually installed on top of the base, which supports and fixes the inner tub. The inner tub and the base are usually directly and rigidly connected by fasteners such as bolts. This connection method requires drilling threaded holes and installing multiple sets of bolts, resulting in low assembly efficiency and high assembly costs. In addition, bolt removal is cumbersome, leading to low efficiency in disassembling and repairing the inner tub later. Utility Model Content

[0004] This application provides a dishwasher to solve the problems of low assembly and disassembly efficiency and high cost in existing dishwashers that use fasteners such as bolts to connect the inner tank and the base.

[0005] In some embodiments, this application provides a dishwasher, comprising:

[0006] The inner liner includes an upper shell and a lower shell, which are connected by an interlocking structure.

[0007] A base is located below the inner liner. The base is provided with an elastic snap-fit ​​structure. The elastic snap-fit ​​structure is configured to extend beyond the bite-edge structure and snap-fit ​​above the bite-edge structure to connect the inner liner and the base when the inner liner is placed on the base, and to move away from the bite-edge structure to release the connection between the inner liner and the base when subjected to external force.

[0008] Compared to related technologies that rigidly connect the inner liner and base using fasteners, resulting in cumbersome assembly and disassembly, this application utilizes a flexible snap-fit ​​structure that engages the inner liner's bite-edge structure. Firstly, simply placing the inner liner on the base achieves the connection between them. The flexible snap-fit ​​structure effectively limits the movement of the inner liner, making the connection quick and easy, which is beneficial for the dishwasher's safety and reliability during transportation and prototype operation. Furthermore, it eliminates the need for threaded holes and bolts, improving assembly efficiency and reducing the additional costs associated with threading. Secondly, when subjected to external force, the flexible snap-fit ​​structure moves away from the bite-edge structure, allowing for quick disassembly of the inner liner and improving maintenance efficiency.

[0009] Furthermore, the dishwasher in this application embodiment cleverly utilizes the original bite-edge structure of the inner tub, which eliminates the need for additional connecting structures to achieve the connection between the inner tub and the base, effectively reducing processing costs and process requirements.

[0010] In some embodiments, the resilient snap-fit ​​structure includes a resilient buckle disposed on the side wall of the base.

[0011] Therefore, the elastic properties of the snap fastener itself allow it to compress first to overcome the bite-edge structure during the installation of the inner liner onto the base, and then return to its original position to lock onto the bite-edge structure, thus fixing and limiting the inner liner. Furthermore, its elastic properties also allow it to be pushed away from the bite-edge structure by external force.

[0012] In some embodiments, the side wall of the base is provided with a mounting hole, and the elastic buckle includes a fixed section, an elastic section and a limiting section connected in sequence. The fixed section is fixedly connected to the top wall of the mounting hole, the elastic section extends downward from the fixed section, and the elastic section is inclined relative to the mounting hole towards the inner liner. The limiting section can engage and limit the area above the bite-edge structure.

[0013] Therefore, the elastic segment of the elastic buckle can achieve the functions of compression and reset, thereby enabling the limiting segment to engage and limit above or away from the bite edge structure.

[0014] In some embodiments, the thickness of the limiting segment gradually decreases along the direction away from the elastic segment.

[0015] In other words, the limiting section has a triangular cross-section, which makes the end of the limiting section form a pointed tip. This tip can then be engaged with the upper part of the bite-edge structure. When the inner liner moves upward due to transportation or prototype operation, the pointed tip can engage with the gap between the bite-edge structure and the outer wall of the upper shell. This allows the bite-edge structure and the limiting section to be engaged in a "plug-in" limiting manner, which can effectively restrict the movement of the inner liner.

[0016] In some embodiments, the elastic buckle further includes a reinforcing rib, one end of which is disposed on the fixed section and the other end of which extends from the fixed section to the elastic section.

[0017] This improves the structural strength of the elastic buckle and prevents it from breaking under stress.

[0018] In some embodiments, two reinforcing ribs are provided, and the two reinforcing ribs are arranged symmetrically with respect to the center of the fixed segment.

[0019] Therefore, while ensuring the elastic function of the elastic buckle, its structural strength is optimized. This also avoids the situation where excessive reinforcing ribs reduce the elasticity of the buckle, preventing it from achieving a flexible connection.

[0020] In some embodiments, the elastic buckle further includes a tie rod disposed on the side of the elastic segment away from the inner liner.

[0021] Based on this, by setting up a tie rod, when it is necessary to disassemble the inner liner, simply use a tool to clamp the tie rod and pull the elastic buckle away from the inner liner. This will cause the elastic buckle to move away from the bite edge structure, disconnecting the connection between the inner liner and the base, making it easier to disassemble the inner liner.

[0022] In some embodiments, a bracket is provided on the top of the side wall of the base, and the mounting hole is formed on the bracket.

[0023] Therefore, on the one hand, the height of the mounting hole can be adjusted by the bracket, so that the elastic buckle can be adapted to the height of the inner liner's bite edge structure. On the other hand, the bracket also provides installation space for the elastic buckle, which facilitates the processing of the elastic buckle.

[0024] In some embodiments, the top of the side wall of the base is provided with a support surface, the bracket is disposed on the support surface, and a portion of the inner liner is supported on the support surface.

[0025] Therefore, the supporting surface can support part of the inner liner. On the one hand, it positions the inner liner on the base. On the other hand, the inner liner is supported on the supporting surface, which also provides stable support for the engagement of the elastic buckle and the bite edge structure. This prevents the elastic buckle from moving away from the bite edge structure due to lack of stable support, which would cause the engagement to fail.

[0026] In some embodiments, the elastic snap-fit ​​structure is provided on both opposite side walls of the base.

[0027] Therefore, the elastic snap-fit ​​structure on both sides can simultaneously limit the movement of the inner liner, effectively improving the connection and limiting strength between the inner liner and the base, and preventing the inner liner from detaching from the base.

[0043] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0044] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0045] In related technologies, dishwashers typically use bolts or other fasteners to connect the inner tub and the base. This method requires drilling holes in both the inner tub and the base, increasing the number of processing steps and costs. Furthermore, assembling the fasteners increases production time, leading to reduced assembly efficiency. On the other hand, when disassembling and repairing the inner tub is necessary, bolt removal (especially if the bolts have rusted over time) is difficult, resulting in low disassembly and repair efficiency.

[0046] In view of the above-mentioned technical problems, this application provides a dishwasher, wherein Figure 1 This is a three-dimensional structural diagram showing the dishwasher described in this embodiment of the application, including an inner tank 1 and a base 2. Figure 1 As shown, the dishwasher includes a base 2 and an inner tub 1, wherein the inner tub 1 can be installed on the base 2. Of course, the dishwasher may also include other components such as spray components and electronic control components located in the inner tub 1, which will not be described in detail in this embodiment.

[0047] In the embodiments of this application, Figure 2 This is a schematic diagram of the inner tank 1 of the dishwasher described in this application embodiment. Figure 3 This is a cross-sectional view of the inner tub of the dishwasher described in the embodiments of this application. Figure 4 Examples of this application Figure 3 An enlarged diagram of point A. (See diagram below.) Figures 2-4 As shown, the inner liner 1 may include an upper shell 11 and a lower shell 12. The lower end of the upper shell 11 is open, and the upper end of the lower shell 12 is open. The opposite ends of the upper shell 11 and the lower shell 12 are provided with flanges. The bottom of the upper shell 11 may have an outwardly folded first flange 111, and the top of the lower shell 12 may have an outwardly folded second flange 121. The first flange 111 and the second flange 121 are interlocked by an interlocking process, so that the first flange 111 and the second flange 121 present a mutually wrapping structure. For example, the first flange 111 may be bent into a U-shaped structure, and the second flange 121 may be bent into an inverted U-shaped structure. The first flange 111 and the second flange 121 are interlocked and pressed together to form an interlocking structure 13, so that the upper shell 11 and the lower shell 12 are fixed and sealed together. It should be noted that the edge-biting process refers to the process of biting the first flange 111 and the second flange 121 together by using an edge-biting machine, so that the first flange 111 and the second flange 121 form an edge-biting structure 13.

[0048] In this embodiment, the base 2 is located at the bottom of the dishwasher, above the inner tub 1, and serves to support the inner tub 1. Figure 5 As shown, Figure 5 This is a schematic diagram of the structure of the dishwasher base 2 according to an embodiment of this application. The base 2 may include a body and an elastic snap-fit ​​structure 21 disposed on the body. The elastic snap-fit ​​structure 21 can snap onto and limit the bite-edge structure 13 of the inner tub 1 to connect the inner tub 1 and the base 2, and can move away from the bite-edge structure 13 when subjected to external force to release the connection between the inner tub 1 and the base 2. Specifically, refer to... Figure 6 and Figure 7 ,in Figure 6 This is a rear view of the dishwasher described in this embodiment, showing the inner tank 1 and the base 2. Figure 7 Examples of this application Figure 6 The enlarged schematic diagram at point B shows that when the inner tub 1 is placed on the base 2, the elastic locking structure 21 can pass over the bite structure 13 and ultimately lock onto the inner tub 1 above the bite structure 13. In other words, the dishwasher of this application only needs to place the inner tub 1 on the base 2 to achieve the connection between the inner tub 1 and the base 2. The elastic locking structure 21 can effectively limit the movement of the inner tub 1, thereby preventing the inner tub 1 from detaching from the base 2, which is beneficial to the safety and reliability of the dishwasher during transportation and prototype operation.

[0049] Furthermore, compared to the cumbersome assembly and disassembly process of rigidly connecting the inner liner 1 and the base 2 with fasteners in related technologies, the embodiment of this application achieves the connection between the inner liner 1 and the base 2 without the need for threaded holes and bolt assembly through the cooperation of the elastic snap-fit ​​structure 21 and the bite-edge structure 13, which improves assembly efficiency and reduces the additional cost required for threaded holes. On the other hand, when the elastic snap-fit ​​structure 21 is subjected to external force, it moves away from the bite-edge structure 13, which can release the connection between the inner liner 1 and the base 2, allowing the inner liner 1 to be disassembled quickly and improving the maintenance efficiency of the inner liner 1.

[0050] Moreover, the dishwasher in this embodiment cleverly utilizes the original bite structure 13 of the inner liner 1, which can connect the inner liner 1 and the base 2 without the need for additional connecting structures, effectively reducing processing costs and process requirements.

[0051] In some embodiments, such as Figure 7As shown, the elastic snap-fit ​​structure 21 of this application may include an elastic buckle disposed on the side wall of the base 2. The elastic buckle itself has a certain elasticity. During the installation of the inner liner 1 on the base 2, the biting edge structure 13 of the inner liner 1 will gradually contact the elastic buckle and first compress the elastic buckle. The elastic buckle can pass over the biting edge structure 13 through its own elasticity, and then reset to snap and limit the inner liner 1 above the biting edge structure 13. At this time, the inner liner 1 can be fixed and limited. When it is necessary to remove the inner liner 1, it is only necessary to apply an external force to the elastic buckle, specifically a force away from the inner liner 1. At this time, the elastic buckle is driven away from the biting edge structure 13 by the external force through its elastic characteristics, that is, it no longer limits the biting edge structure 13, and then the inner liner 1 can be removed.

[0052] For reference Figures 7-9 ,in Figure 8 Examples of this application Figure 5 Enlarged diagram of point C, Figure 9 Examples of this application Figure 5 The enlarged schematic diagram at point D shows the aforementioned elastic buckle, which can be installed on the top side wall of the base 2. Specifically, a bracket 23 can be installed on the top side wall of the base 2, extending upwards along the top of the side wall. A mounting hole 22 is provided on the bracket 23, and the elastic buckle is connected to the inner top wall of the mounting hole 22. The elastic buckle is inclined relative to the mounting hole 22 to allow for elastic compression. This mounting hole 22 facilitates the compression and release of the elastic buckle. Furthermore, when the inner liner 1 needs to be disassembled, external force can be applied to the elastic buckle through the mounting hole 22 to drive it away from the bite-edge structure 13.

[0053] Furthermore, in this embodiment of the application, a bracket 23 is provided on the top of the side wall of the base 2, which can adjust the height of the mounting hole 22 according to the height of the bite structure 13 of different inner liner 1, so that the elastic buckle in the mounting hole 22 can be adapted to the height of the bite structure 13 of the inner liner 1. Moreover, the bracket 23 also provides installation space for the elastic buckle, which facilitates the processing of the elastic buckle.

[0054] As one implementation method, such as Figure 9 As shown, in this embodiment of the application, a support surface 24 can be provided on the top of the side wall of the base 2, and the aforementioned bracket 23 is disposed on the support surface 24. A portion of the inner liner 1 (specifically, a portion of the lower shell 12) is supported on the support surface 24. The provision of the support surface 24 serves two purposes: firstly, it positions the inner liner 1 on the base 2, ensuring precise placement of the inner liner 1 on the base 2, and the support surface 24 provides strong support for the inner liner 1. Secondly, the partial support of the inner liner 1 on the support surface 24 also provides stable support for the engagement of the elastic buckle and the bite-edge structure 13, preventing the elastic buckle from moving away from the bite-edge structure 13 due to a lack of stable support, thus avoiding engagement failure.

[0055] In this embodiment, elastic locking structures 21 are provided on both opposite side walls of the base 2. Thus, the elastic locking structures 21 on both sides can simultaneously limit the movement of the inner liner 1, effectively improving the connection strength between the inner liner 1 and the base 2 and preventing the inner liner 1 from detaching from the base 2. Exemplarily, each side wall can also be provided with multiple elastic locking structures 21 as needed to improve the limiting effect on the inner liner 1.

[0056] Optionally, the flexible snap-fit ​​structure 21 can be set on the side wall of the base 2 at the position corresponding to the rear end of the inner tub 1. This position can provide installation space for the flexible snap-fit ​​structure 21, thereby improving the space utilization of the dishwasher.

[0057] In some embodiments, refer to Figures 8-10 The elastic buckle may include a fixed section 211, an elastic section 212, and a limiting section 213 connected in sequence. The fixed section 211 is fixedly connected to the top wall of the mounting hole 22. The elastic section 212 extends downward from the fixed section 211 and is inclined, with the inclination direction of the elastic section 212 relative to the mounting hole 22 towards the inner liner 1. The limiting section 213 is connected to the end of the elastic section 212 and is used to engage and limit the position above the bite-edge structure 13. This structural arrangement allows the elastic buckle to be connected within the mounting hole 22. Furthermore, the inclined elastic section 212 can achieve elastic compression and reset, thereby allowing the limiting section 213 to engage and limit the position above the bite-edge structure 13 to complete the connection between the inner liner 1 and the base 2, or to move away from the bite-edge structure 13 to complete the disassembly of the inner liner 1.

[0058] In some embodiments, the thickness of the limiting segment 213 gradually decreases along the direction away from the elastic segment 212. The limiting segment 213, with its gradually decreasing thickness, has a triangular cross-section, so that the end of the limiting segment 213 forms a pointed tip, which can then engage with the upper part of the bite-edge structure 13. When the inner liner 1 moves upward due to transportation or prototype operation, the pointed tip can engage with the gap between the bite-edge structure 13 and the outer wall of the upper shell 11, thereby making the bite-edge structure 13 and the limiting segment 213 present an "insertion" limiting method, which can effectively restrict the movement of the inner liner 1.

[0059] like Figure 10As shown, the elastic buckle in this embodiment of the application also includes a reinforcing rib 214. One end of the reinforcing rib 214 is disposed at the fixed section 211, and the other end extends from the fixed section 211 to the elastic section 212. That is, the reinforcing rib 214 extends in the direction from the fixed section 211 to the elastic section 212. Thus, the reinforcing rib 214 can improve the structural strength of the elastic buckle and prevent the elastic buckle from breaking under force. It should be noted that the width and thickness of the reinforcing rib 214 should not be too large to prevent the elastic compression and reset functions of the elastic buckle from being limited. In some embodiments, preferably, two reinforcing ribs 214 can be provided, and the two reinforcing ribs 214 are arranged symmetrically with respect to the center of the fixed section 211. On the one hand, if only one reinforcing rib 214 is provided, the structural strength of the elastic buckle may be insufficient; if three or more reinforcing ribs 214 are provided, the elastic compression and reset functions of the elastic buckle will be limited. Based on this, the embodiment of the application provides two reinforcing ribs 214, which can achieve optimal structural strength while ensuring the elastic function of the elastic buckle.

[0060] In some embodiments, such as Figure 10 As shown, the elastic buckle also includes a tie rod 215, which is located on the side of the elastic segment 212 away from the inner liner 1, and can be inserted into the mounting hole 22. By providing the tie rod 215, when it is necessary to disassemble the inner liner 1, simply use a tool to clamp the tie rod 215 and pull the elastic buckle away from the inner liner 1, so that the elastic buckle is moved away from the bite structure 13, thereby detaching the connection between the inner liner 1 and the base 2, facilitating the disassembly of the inner liner 1.
