Description

Technical Field

[0001] This application pertains to the field of dishwashing, and more specifically, relates to a dishwasher. Background Technology

[0002] Dishwashers are primarily used for cleaning tableware and kitchen utensils. During long-term use, their internal components require maintenance and repair. Therefore, they typically have access panels on the cabinet, usually sealed with an openable access cover. Existing access covers are often connected to mounting bases via hinges, bolts, or snap-fit ​​mechanisms, which reduces the overall assembly efficiency of the dishwasher. Utility Model Content

[0003] The purpose of this application is to provide a dishwasher to solve the technical problem in the prior art where the assembly of the access cover reduces the assembly efficiency of the dishwasher.

[0004] To achieve the above objectives, the technical solution adopted in this application is: to provide a dishwasher, which includes a cabinet, the cabinet comprising:

[0005] Mounting base; The mounting base is equipped with an access port that connects to the interior of the housing;

[0006] Inspection cover; The inspection cover is connected to the mounting base and closes the inspection port;

[0007] The inspection cover and the mounting base are integrally formed. The first side of the inspection cover and the mounting base have a first folding part. The inspection cover is configured to be able to flip around the first folding part to open or close the inspection port.

[0008] The access cover has a first connection between at least one other side, different from the first side, and the mounting base. The first connection is configured to be disconnectable to allow the access cover to be flipped around the first hinge.

[0009] Compared with the prior art, the dishwasher in this embodiment has an integrated service cover and mounting base, reducing the number of molds and thus lowering manufacturing costs. The integrated service cover and mounting base are connected during the production stage, eliminating the need for additional assembly steps during the dishwasher's final assembly, thereby improving the assembly efficiency of the service cover and the overall production efficiency of the dishwasher. The integrated service cover and mounting base are connected by a first hinge and a first connecting part. Disconnecting the first connecting part allows the service cover to be flipped open via the first hinge, ensuring that the service cover still meets the needs for later opening and maintenance.

[0010] Optionally, the mounting base is located at the bottom of the cabinet to form the base of the cabinet, and the access cover is located at the bottom of the mounting base to form the bottom cover of the cabinet. Using the bottom cover on the base as the access cover can ensure the aesthetics of the dishwasher and reduce collisions with the access cover.

[0011] Optionally, a first gap exists between the side of the inspection cover with the first connecting portion and the mounting base. The first connecting portion includes at least one connecting rib, which spans the first gap to connect the inspection cover and the mounting base. The presence of the first gap ensures that the inspection cover and the mounting base are separated to a certain extent, so that the inspection cover can be opened after the connecting rib is cut off.

[0012] Optionally, the access cover has at least one other side different from the first side, and the second connection is configured to be detachably connected to the mounting base when the first connection is disconnected, so that the access cover can be opened and closed again when the first connection is disconnected.

[0013] Optionally, the second connecting part is provided on the second side of the inspection cover, which is opposite to the first side. This can maintain the stability of the inspection cover while reducing the number of second connecting parts.

[0014] Optionally, a second gap exists between the second connecting portion and the mounting base; the dishwasher also includes a first pad, which is connected to the mounting base or the access cover via a second hinge. The first pad is configured to fold around the second hinge into the second gap to provide support between the second connecting portion and the mounting base. With the support of the first pad, the second connecting portion can remain in its original position even when the first connecting portion is disconnected, thereby maintaining the closed position of the access cover.

[0015] Optionally, the first pad is connected to the mounting base, and the first pad is located outside the orthographic projection area of ​​the second connecting portion. The first pad is configured to be able to flip around the second hinge portion into the orthographic projection area of ​​the second connecting portion, so that the first pad is within the second gap. The initial position of the first pad is outside the orthographic projection area of ​​the second connecting portion to avoid interference and adhesion between the two during the integral molding process. By flipping, the first pad can be placed within the orthographic projection area of ​​the second connecting portion, thereby playing a supporting role.

[0016] Optionally, the second connecting portion is provided with a receiving groove, and the first pad is disposed in the receiving groove and connected to the second connecting portion via a second hinge portion. The first pad is configured to be able to flip around the second hinge portion to the side of the second connecting portion facing the mounting base, so that the first pad is located within the second gap. The first pad being disposed in the receiving groove reduces the area occupied by the first pad, and when it is needed to provide support, it can be directly flipped to the side of the second connecting portion facing the mounting base, thereby providing support between the second connecting portion and the mounting base.

[0017] Optionally, the second connecting part is provided with a first connecting hole for the first connecting member to pass through, and the second connecting part can be connected to the mounting base through the first connecting member; the number of first pads is at least two, and when the first pads are flipped into the second gap, first pads are provided on at least both sides of the first connecting hole, so that the first pads can be supported at least on both sides of the first connecting member. The first pads on both sides can maintain the balance of support, thereby improving the stability of the connection.

[0018] Optionally, the first pad is provided with a first clearance groove. When the first pad is flipped into the second gap, the position of the first connecting hole is opposite to the first clearance groove, so that the first pad can be supported at least on both sides of the first connector. The first clearance groove can also achieve lateral support of the first pad and can reduce the number of first pads.

[0019] Optionally, the first side of the inspection cover has a third connecting portion, which is configured to be detachably connected to the mounting base in the event of damage to the first hinge portion. The third connecting portion serves as a backup and can function even if the first hinge portion is damaged, thus allowing the inspection cover to still be securely connected via the third connecting portion.

[0020] Optionally, a third gap exists between the third connecting portion and the mounting base; the dishwasher also includes a second pad, which is connected to the mounting base or access cover via a third hinge. The second pad is configured to fold around the third hinge into the third gap to support the third connecting portion and the mounting base. The presence of the third gap separates the third connecting portion from the mounting base, preventing them from sticking together during the molding process. The supporting effect of the second pad allows the third connecting portion to remain in its original position during connection, thereby keeping the access cover in its original position.

[0021] Optionally, the third connecting part is provided with a second connecting hole for the second connecting member to pass through, and the third connecting part can be connected to the mounting base through the second connecting member; the second pad is provided with a second relief groove, and when the second pad is flipped into the third gap, the position of the second connecting hole is opposite to the second relief groove, so that the second pad can be supported at least on both sides of the second connecting member. The provision of the second relief groove can also achieve balanced support on both sides and can reduce the number of first pads.

[0022] Optionally, at least two second pads are provided. When the second pads are flipped into the third gap, second pads are provided on at least both sides of the second connecting hole so that the second pads can be supported on at least both sides of the second connector. The second pads on both sides can maintain the balance of support, thereby improving the stability of the connection of the third connecting part. Attached Figure Description

Detailed Implementation

[0039] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0040] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0041] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0043] Dishwashers are widely used kitchen appliances in modern homes and commercial catering settings. They replace manual operation with automated processes to achieve efficient cleaning of tableware and cookware. In addition to removing food residue and grease from the surface of dishes, some models also integrate functions such as drying, sterilization, and antibacterial storage. This effectively reduces the intensity of manual labor, improves the cleanliness and hygiene of tableware, and meets the needs of daily home use as well as large-scale commercial applications.

[0044] A dishwasher mainly consists of a water inlet system, a heating system, a spray system, a drainage system, and a control system. The water inlet system includes an inlet valve and inlet pipes, responsible for introducing clean water; the core of the heating system is the heating device, used to increase the temperature of the incoming water; the spray system consists of a high-pressure water pump, spray arms, and spray nozzles, and is a key structure for removing stains; the drainage system includes a drain pump and drain pipes, responsible for discharging wastewater; and the control system coordinates the operation of each system through program instructions.

[0045] When the dishwasher is running, the internal water inlet valve automatically connects to the water source to introduce clean water. After the clean water is heated by the heating device, it can significantly improve the efficiency of decomposing oil stains. Then, the high-pressure water pump pressurizes the mixture of hot water and detergent. The pressurized mixture is sprayed out at high speed through the spray arms set on the inner wall of the machine. The spray arms rotate under the action of the water flow reaction force, so that the water flow can cover the dishes to be washed in all directions and use the impact force of the water flow to remove stains. After the washing process is completed, the wastewater is discharged from the equipment by the drain pump. Some models will start multiple water rinsing processes to remove residual detergent. Finally, the dishes are dried by hot air or condensation.

[0046] Dishwashers integrate precision components such as water pumps, motors, heating elements, and pipe interfaces. Over long-term operation, they are prone to malfunctions such as pipe blockage, component aging, and seal failure. Therefore, a dedicated access port and a matching access cover are necessary. The access port's design must balance concealment and ease of access, typically located at the bottom or back of the dishwasher. In related technologies, the dishwasher base, as the foundation supporting the main body and housing the bottom pipes and core components, has an access port of appropriate size. This access port is sealed by a matching bottom cover, which also serves as the access cover. During normal use, the bottom cover is securely connected to the base via clips, bolts, or hinges, effectively preventing sewage and debris from entering the base and damaging components, while also maintaining the integrity of the appliance's appearance. When it is necessary to inspect, repair, or replace components such as the drain pump, pipe joints, and motor wiring inside the base, the bottom cover can be opened according to operating procedures. For example, by disengaging the clips and removing the fixing bolts, the target component can be directly accessed through the access port, significantly reducing the difficulty and labor costs of maintenance.

[0047] Since the access cover needs to be opened during later maintenance of the dishwasher, existing technologies generally adopt a split design and production method. The access cover and the corresponding mounting base for installing the access cover need to be manufactured as two independent parts: each requires a dedicated mold to be made according to its own structural dimensions and molding requirements. After the molds are developed, they enter the production stage separately to form independent finished parts. When the dishwasher enters the final assembly stage, the manufactured access cover and mounting base are aligned and assembled to form a complete access opening and closing structure.

[0048] This approach has significant drawbacks: on the one hand, the design, manufacturing, and subsequent maintenance of two independent molds require double the cost, including mold material costs, processing time costs, and mold management costs, which directly increases the overall manufacturing cost of the parts; on the other hand, the assembly process of the inspection cover during final assembly prolongs the production line's cycle time and significantly reduces the assembly efficiency of the inspection cover and the entire machine.

[0049] Based on the above issues, please refer to Figures 1 to 7 The dishwasher provided in the embodiments of this application will now be described. The dishwasher includes a cabinet, and the cabinet includes:

[0050] Mounting base 1; Mounting base 1 is provided with an inspection port 11, which connects to the interior of the housing;

[0051] Inspection cover 2; Inspection cover 2 is connected to mounting base 1 and closes inspection port 11;

[0052] The inspection cover 2 and the mounting base 1 are integrally formed. The first side 21 of the inspection cover 2 has a first folding part 3 between it and the mounting base 1. The inspection cover 2 is configured to be able to be flipped around the first folding part 3 to open or close the inspection port 11.

[0053] The access cover 2 has at least one other side different from the first side 21 between itself and the mounting base 1, and the first connection 4 is configured to be disconnected to allow the access cover 2 to be flipped around the first hinge 3.

[0054] like Figure 1 As shown, the external components of the dishwasher mainly include the cabinet 10 and the door 20. The cabinet 10 is mainly used to house the tableware and cookware to be washed, while the door 20 is used to close the opening on the cabinet for taking out and putting in the tableware and cookware. Figure 1 and Figure 2 As shown, the mounting base 1, as a component of the enclosure, serves as the supporting foundation for the inspection port 11. The inspection port 11 on its surface allows communication between the interior and exterior of the enclosure, providing a passage for equipment maintenance, and also serves to install and position the inspection cover 2. Figure 3 and Figure 4 As shown, the inspection cover 2 is a sealing component used in conjunction with the mounting base 1. By connecting with the mounting base 1, it seals the inspection port 11, preventing sewage and debris from entering the interior of the box during use. It also has an openable and closable feature to meet maintenance needs.

[0055] The first hinge section 3 is an integrally formed structure located between the first side 21 of the inspection cover 2 and the mounting base 1. It is usually a specially designed weak part between the inspection cover 2 and the mounting base 1. It has bendable flexibility, thus forming a hinge structure, providing a rotation fulcrum for the flipping action of the inspection cover 2, and is the core structure for realizing the opening and closing of the inspection port 11.

[0056] The first connecting part 4 is provided on at least one other side of the inspection cover 2 other than the first side 21. In the initial state, the inspection cover 2 and the mounting base 1 are tightly connected through the first connecting part 4, ensuring the sealing of the inspection port 11, and the connection restriction can be released by disconnection. Figures 4 to 7 In the embodiments, Figure 5 , Figure 6 ,and Figure 7 They are respectively Figure 4 The enlarged views at points A, B, and C show the other three sides of the inspection cover 2 besides the first side 21. Each of these three sides has a first connecting portion 4 to connect the inspection cover 2 to the mounting base 1. In some embodiments, multiple first connecting portions 4 can be spaced apart on each of these three sides to improve connection stability. In other embodiments, the first connecting portions 4 can be provided only on one or both sides of the inspection cover 2. For example, the first connecting portion 4 can be provided only on the opposite side of the first side 21 of the inspection cover 2, or only on adjacent sides of the first side 21.

[0057] The inspection cover 2 is initially in a closed state. It is connected to the mounting base 1 through the first hinge part 3, and the other sides except the first side 21 are fixed to the mounting base 1 through the first connecting part 4. At this time, the inspection cover 2 tightly covers the inspection port 11, achieving sealing protection of the inside of the box.

[0058] When equipment maintenance is required, apply external force to the first connecting part 4 to disconnect it. Use tools such as scissors to cut it open, releasing the connection constraint between the maintenance cover 2 and the mounting base 1 except for the first hinge part 3. Then, using the first hinge part 3 as a rotation axis, flip the maintenance cover 2 outward around it to open the maintenance opening 11 and expose the internal structure of the housing. After maintenance is completed, flip the maintenance cover 2 in the opposite direction around the first hinge part 3 to cover the maintenance opening 11 again. If it is necessary to restore the seal, a secondary connection can be made through the reserved connecting part or by re-drilling holes to re-fix the maintenance cover 2 and the mounting base 1.

[0059] Since the inspection cover 2 and the mounting base 1 are integrally molded, there is no need to create two separate molds as in traditional solutions. Only one mold is needed to complete the simultaneous production of both. This design eliminates the additional costs of mold design, manufacturing, and subsequent maintenance, including investment in mold materials, processing time, and management, directly reducing the overall manufacturing cost of the components.

[0060] The integrated molding structure completes the connection between the inspection cover 2 and the mounting base 1 during the production stage, eliminating the need for additional assembly steps of the inspection cover 2 and mounting base 1 during the dishwasher assembly stage. This significantly shortens the production line cycle time and effectively improves the assembly efficiency of the inspection cover 2 and the entire machine.

[0061] The first hinge part 3 is integrally formed with both parts. Compared with the traditional split assembly connection structure, it reduces the assembly gap and the risk of loose connection, and can stably support the flipping action of the inspection cover 2 for a long time. The integral connection of the first connecting part 4 in the initial state also ensures the sealing of the inspection port 11, reducing the possibility of connection failure that may occur in split assembly.

[0062] In some embodiments of this application, the integral molding process of the inspection cover 2 and the mounting base 1 can be achieved by injection molding. Taking the commonly used PP material (polypropylene) as an example, the specific process is as follows: First, an integrated mold is designed according to the overall structure of the inspection cover 2, the mounting base 1, the first folding part 3 and the first connecting part 4. The mold cavity needs to accurately match the size parameters of each component, especially the first folding part 3, which needs to reserve a thin-walled structure to adapt to its bending characteristics. Then, the molten PP material is injected into the mold cavity. The good toughness of the PP material itself can ensure that the first folding part 3 still maintains excellent bendability after molding, avoiding the failure of the flipping function due to the integrated structure. After the material cools and solidifies in the mold, the mold can be opened to obtain a molded part that integrates the mounting base 1, the inspection cover 2, the first folding part 3 and the first connecting part 4. The pre-connection of the two can be completed without subsequent additional assembly, and the first folding part 3 can directly realize the flipping action of the inspection cover 2.

[0063] In addition to PP (polypropylene), the dishwasher bottom cover can also be made of modified PP (modified polypropylene), HDPE (high-density polyethylene), ABS resin (acrylonitrile-butadiene-styrene copolymer), etc., all of which can meet the requirements of the one-piece molding process and the performance requirements of the dishwasher mounting base 1 and the inspection cover 2.

[0064] Please see Figure 1 In some embodiments of this application, the mounting base 1 is disposed at the bottom of the box to form the base of the box, and the inspection cover 2 is disposed at the bottom of the mounting base 1 to form the bottom cover of the box.

[0065] The base and bottom cover are common structures for dishwasher cabinets. When the mounting base 1 is set at the bottom of the cabinet as a base, it needs to bear the weight of the main body of the dishwasher and the load of core components such as the internal water pump and motor. At the same time, it provides installation space for components such as bottom pipes and wiring. The access port 11 opened on it becomes a convenient channel to directly access these key bottom components, realizing the integration of support function and maintenance function.

[0066] The inspection cover 2 is correspondingly installed at the bottom of the mounting base 1 to form a bottom cover, making it a closed protective structure at the bottom of the housing. The bottom cover is not only tightly connected to the base through the first folding part 3 and the first connecting part 4 to prevent dust and debris from entering the base and corroding the components, but also needs to take advantage of the folding characteristics of the first folding part 3 to quickly open during maintenance, exposing the pipes, pumps and other components inside the base, thus balancing protection and maintainability.

[0067] Please see Figures 4 to 7 In some embodiments of this application, the side of the inspection cover 2 with the first connecting portion 4 has a first gap 41 with the mounting base 1. The first connecting portion 4 includes at least one connecting rib, which spans the first gap 41 to connect the inspection cover 2 and the mounting base 1.

[0068] The first gap 41 is designed to pre-separate the inspection cover 2 from the mounting base 1, providing a foundation for the smooth opening of the inspection cover 2. The inspection cover 2 is connected to the mounting base 1 via the first hinge 3. The non-hinged side needs to be separable to allow for flipping. If this side has no gap and is largely attached, even if the connecting rib is cut, the two will be difficult to separate due to friction or interference, causing the flipping to stall. Therefore, the first gap 41 keeps most of the non-hinged side of the inspection cover 2 and the mounting base 1 separated, with only partial connection achieved through the connecting rib. The two ends of the connecting rib are fixed to the corresponding positions on the side of the inspection cover 2 and the mounting base 1, respectively, while the middle is suspended inside the gap, forming a bridging structure with both ends fixed and the middle suspended. This achieves pre-separation through the gap and ensures initial sealing stability through the connecting rib.

[0069] During daily use of the dishwasher, external impacts or internal pressures are transmitted to one end of the connecting rib through the inspection cover 2, and then to the other end of the mounting base 1 through the middle suspended section. The force is concentrated at the connection points at both ends, without any additional contact points to interfere, ensuring connection strength and sealing performance.

[0070] When it is necessary to open the inspection cover 2, scissors can be inserted into the first gap 41 and applied directly to the middle of the connecting rib suspended in the gap. Since the connecting rib is a thin-walled structure, the shearing force applied by the scissors can quickly cut the rib and realize the connection separation. There is no need to apply too much external force to the inspection cover 2. Separation can be completed by precisely cutting the rib with the tool, avoiding deformation of the inspection cover 2 and the mounting base 1 due to force.

[0071] After the connecting rib is cut, the clearance space provided by the first gap 41, combined with the pre-separated state of the two, allows the inspection cover 2 to quickly detach from the mounting base 1 without additional peeling, and smoothly flip around the first hinge 3, avoiding jamming caused by frictional resistance. The cooperation between the pre-separation and the bridging structure allows the scissors to directly insert into the gap to cut the connecting rib, and the inspection cover 2 can then be directly flipped, eliminating the peeling step, shortening the operation time, and adapting to the needs of rapid maintenance.

[0072] Please see 2 and Figure 3 In some embodiments of this application, the access cover 2 has at least one other side different from the first side 21, and the second connection portion 5 is configured to be detachably connected to the mounting base 1 when the first connection portion 4 is disconnected.

[0073] The second connecting part 5 is located on at least one other side of the inspection cover 2 that is different from the first side 21. Its core function is to provide a reusable and detachable connection between the inspection cover 2 and the mounting base 1 after the first connecting part 4 is disconnected. The first connecting part 4 is a one-time breakage structure. After disconnection, the inspection cover 2 is only connected to the mounting base 1 through the first hinge part 3. Although it can be flipped open, it is quite troublesome to temporarily fix it during maintenance and reseal it after maintenance.

[0074] The first connecting part 4 is a one-time breakage structure; once disconnected, it loses its connecting function. At this time, the inspection cover 2 is only rotatably connected to the mounting base 1 through the first hinge part 3, possessing the ability to flip open but lacking effective fixing constraints. The second connecting part 5 is located on the side of the inspection cover 2 other than the first hinge part 3. Its structural characteristics determine that it can be detachably connected to the mounting base 1, which precisely makes up for the functional gap after the first connecting part 4 is disconnected.

[0075] After the first connecting part 4 is disconnected, during the maintenance operation start phase, the connection between the second connecting part 5 and the mounting base 1 is released, and the maintenance cover 2 can be flipped open around the first folding part 3 to provide operating space for the maintenance of internal components of the box; after the maintenance operation is completed, the maintenance cover 2 is reset to the initial closed position, and the connection between the second connecting part 5 and the mounting base 1 is re-established to achieve the closure of the maintenance port 11.

[0076] On the one hand, the detachable nature of the second connecting part 5 supports repeated switching of the connection state, allowing the inspection cover 2 to be opened and closed multiple times even after the first connecting part 4 is disconnected, reducing the difficulty of opening and closing the inspection cover 2 again. On the other hand, in the closed state, the second connecting part 5 provides a stable fixing constraint for the inspection cover 2, avoiding structural shaking caused by relying solely on the first hinge part 3 for connection, while ensuring the sealing performance of the inspection port 11, effectively preventing external dust and sewage from entering the interior of the box.

[0077] Please see Figure 3 and Figure 4 In some embodiments of this application, the second connecting part 5 is disposed on the second side 22 of the inspection cover 2, and the second side 22 is the opposite side of the first side 21.

[0078] The second connecting part 5 is located on the opposite side of the first side 21, which is the side where the first folding part 3 is located. Essentially, it constructs a two-point support structure with a single-point fixation and a single-point rotation. The first folding part 3 serves as a rotation fulcrum, and its structural characteristics determine that it can provide stable support for the inspection cover 2 along the flipping axis, and can bear the weight of the inspection cover 2 itself and external radial forces. The second connecting part 5 on the second side 22 serves as a fixing point, which can counteract the axial offset force and overturning moment of the inspection cover 2 in the closed state.

[0079] The force balance system formed by the two-point support eliminates the dependence of the maintenance cover 2's stability on multiple dispersed connection points. In traditional asymmetrical layouts, multiple second connection parts 5 are required to compensate for uneven force distribution caused by the offset of the support points. However, in the opposite-side layout, a single or a small number of second connection parts 5 can achieve overall force balance of the maintenance cover 2 through their diagonal support relationship with the first folding part 3, thus reducing the requirement for the number of second connection parts 5.

[0080] Reducing the number of second connecting parts 5 directly reduces the number of steps involved in connecting and disconnecting. If there is only one second connecting part 5 on the opposite side, only this single component needs to be operated during maintenance to complete the fixing or separation. Compared to the process of operating multiple connecting parts one by one, this significantly shortens the maintenance time per operation. At the same time, the reduced number makes the connection location clearer, allowing non-professionals to quickly locate the operating point, further improving the convenience of maintenance.

[0081] Fewer second connecting parts 5 mean a simpler mold cavity design, reducing the number of inserts or structural units during injection molding, and lowering the difficulty of mold processing and manufacturing costs. At the same time, the reduced number of connecting parts makes the surface structure of the inspection cover 2 more regular, reduces stress concentration points during molding, lowers the probability of component deformation, and improves dimensional consistency during mass production, indirectly improving the overall stability after assembly.

[0082] Please see Figure 8 and Figure 9 In some embodiments of this application, the second connecting part 5 and the mounting base 1 have a second gap 51; the dishwasher also includes a first pad 52, which is connected to the mounting base 1 or the access cover 2 via a second hinge part 521. The first pad 52 is configured to be able to be flipped around the second hinge part 521 into the second gap 51 to be supported between the second connecting part 5 and the mounting base 1.

[0083] The second gap 51 between the second connecting part 5 and the mounting base 1 provides a separation space for the two to be integrally molded, so as to avoid the structural connection during injection molding, which would prevent the inspection cover 2 from being unable to detach from the mounting base 1, and ensure that the inspection cover 2 has basic opening conditions after molding.

[0084] After the first connecting part 4 is disconnected, the unsupported second connecting part 5 is prone to positional deviation due to the second gap 51 used for molding, causing the inspection cover 2 to close and shift. The first pad 52 flips into the gap to form a rigid support, and the second connecting part 5 is fixed in the initial closed position by the size-matched structure filling, which is precisely aligned with the rotation fulcrum of the first folding part 3, ensuring that the contact surface of the inspection cover 2 and the mounting base 1 are completely aligned, avoiding one-sided lifting and misalignment, maintaining the consistency of the closed state, and not affecting the molding and separation function of the gap.

[0085] When the dishwasher vibrates during operation or experiences minor impacts during maintenance, the supporting force of the first pad 52 can directly offset the external force acting on the second connecting part 5, preventing it from wobbling within the second gap 51. Compared to an unsupported gap structure, this rigid filling makes the closed state of the inspection cover 2 more stable, preventing the closed position from changing due to external forces and reducing the risk of seal failure caused by positional displacement. The first pad 52 is directly connected to the mounting base 1 or the inspection cover 2 via the second hinge part 521, which is an integrated structural design. Users do not need to prepare additional pads, completely eliminating the step of finding and adapting external pads.

[0086] Please see Figure 8 and Figure 9 In some embodiments of this application, the first pad 52 is connected to the mounting base 1, and the first pad 52 is located outside the orthographic projection area of ​​the second connecting portion 5. The first pad 52 is configured to be able to flip around the second folding portion 521 into the orthographic projection area of ​​the second connecting portion 5, so that the first pad 52 is in the second gap 51.

[0087] The first pad 52 is connected to the mounting base 1, which provides a fixed base point for the pad. The first pad 52 is initially located outside the orthographic projection area, completely avoiding structural interference with the inspection cover 2. When the inspection cover 2 is closed via the second connecting part 5, the first pad 52 needs to provide support. At this time, the first pad 52 is flipped to a predetermined support position via the second hinge part 521. After the second connecting part 5 is pressed down to cover, the two form a tightly fitting support relationship, limiting the displacement of the second connecting part 5 and thus holding the inspection cover 2 in a preset position.

[0088] Please see Figure 10 In some embodiments of this application, a receiving groove is provided on the second connecting part 5, the first pad 52 is disposed in the receiving groove and connected to the second connecting part 5 through the second folding part 521, and the first pad 52 is configured to be able to flip around the second folding part 521 to the side of the second connecting part 5 facing the mounting base 1, so that the first pad 52 is in the second gap 51.

[0089] When the first connecting part 4 is not disconnected, the first pad 52 is housed in the receiving groove of the second connecting part 5, forming an integrated structure with the second connecting part 5, and is synchronously in its original position with the inspection cover 2. After the first connecting part 4 is disconnected, during the closing process of the inspection cover 2, the second connecting part 5 moves towards the mounting base 1. At this time, the first connecting part 4 in the receiving groove can be directly flipped around the hinge to the side facing the mounting base 1. The first pad 52 moves synchronously with the second connecting part 5. When the second connecting part 5 is closed to the predetermined position, the first pad 52 is naturally located in the second gap 51.

[0090] The first pad 52 and the second connecting part 5 are designed as an integrated unit, so the user does not need to find or locate the first pad 52 separately. Before the inspection cover 2 is closed, the user only needs to flip the first pad 52 on the second connecting part 5, which makes the operation simpler.

[0091] The first pad 52 and the second connecting part 5 are rigidly connected via the second hinge part 521. After flipping, the support angle and position are fixed and will not shift due to vibration or opening / closing operations. Simultaneously, the receiving groove provides storage and restraint for the first pad 52, preventing it from wobbling when unsupported and avoiding collisions and wear with other components. The receiving groove integrates the first pad 52 inside the second connecting part 5, eliminating the need for additional space in the mounting base 1, resulting in a more compact overall structure suitable for the limited installation space inside the dishwasher. Furthermore, the integrated design does not alter the original dimensions of the second connecting part 5, ensuring that the access cover 2 can still precisely fit the surrounding structure after closing, without affecting the internal space layout or the function of other components.

[0092] Please see Figure 10 In some embodiments of this application, the second connecting portion 5 is provided with a first connecting hole 53 for the first connecting member to pass through, and the second connecting portion 5 can be connected to the mounting base 1 through the first connecting member. The number of first pads 52 is at least two. When the first pads 52 are flipped into the second gap 51, at least the first pads 52 are provided on both sides of the first connecting hole 53, so that the first pads 52 can be supported at least on both sides of the first connecting member.

[0093] The number of first pads 52 is set to at least two. When flipped for support, at least one first pad 52 is arranged on each side of the first connecting hole 53 to support both sides of the first connector. After the first connecting part 4 is disconnected, when the inspection cover 2 is closed again, the weight of the second connecting part 5 and the external pressure can be synchronously transmitted to the mounting base 1 through the first pads 52 on both sides. Compared with the overall support of a single first pad 52, the multi-pad design can distribute the concentrated load to multiple support points and avoid support failure caused by overload of a single support point.

[0094] Please see Figure 11 and Figure 12 In some embodiments of this application, the first side 21 of the inspection cover 2 has a third connecting portion 6, which is configured to be detachably connected to the mounting base 1 in the event of damage to the first folding portion 3.

[0095] The first hinge section 3 serves as the core rotating connection structure between the inspection cover 2 and the mounting base 1, providing a rotation fulcrum and assisting in positioning under normal conditions. If damaged by wear, breakage, or other reasons, the original rotation fulcrum and positional constraints fail, making the inspection cover 2 prone to detachment or loss of positional control. In this case, the third connecting section 6 can replace the constraint function of the first hinge section 3, reconstructing a stable fulcrum through a detachable connection with the mounting base 1, filling the functional gap, and forming an emergency connection solution. Users can quickly assemble it without professional tools, restoring the basic closing and positioning functions of the inspection cover 2, ensuring the dishwasher can be used temporarily before the first hinge section 3 is repaired, reducing usage interruptions caused by malfunctions, and adapting to emergency needs in non-professional repair scenarios such as home use.

[0096] Meanwhile, the third connecting part 6 and the second connecting part 5 form a distributed layout on the inspection cover 2. Under normal conditions, they are in a standby state. In the event of damage, they connect with the mounting base 1, thereby working in conjunction with the supporting effect of the second connecting part 5 and the first pad 52 to construct a multi-point positioning system. This layout, with multiple parts jointly constraining each other, can lock the inspection cover 2 in a preset closed position, preventing it from colliding and rubbing against surrounding components due to loss of rotational constraint, reducing the risk of escalation of the fault, and providing a stable operating basis for subsequent maintenance.

[0097] In some embodiments of this application, to facilitate the connection between the third connecting part 6 and the mounting base 1, a reserved connecting structure 63 may be provided on the mounting base 1. The reserved connecting structure 63 and the third connecting part 6 are positioned opposite each other, and the mounting base 1 is connected to the third connecting part 6 through the reserved connecting structure 63. Similarly, a reserved connecting structure 63 may also be provided on the mounting base 1 corresponding to the second connecting part 5.

[0098] Please see Figure 12 In some embodiments of this application, the third connecting part 6 and the mounting base 1 have a third gap 61; the dishwasher also includes a second pad 62, which is connected to the mounting base 1 or the access cover 2 via a third hinge part 521. The second pad 62 is configured to be able to be flipped around the third hinge part 521 into the third gap 61 to be supported between the third connecting part 6 and the mounting base 1.

[0099] The third gap 61 is to ensure that the third connecting part 6 and the mounting base 1 are separated when they are integrally formed, so that the inspection cover 2 can be opened during later maintenance.

[0100] After the first hinge 3 is damaged, although the third connecting part 6 can form a detachable connection with the mounting base 1, the presence of the third gap 61 will prevent the two from fitting tightly. Relying solely on the connecting structure may result in insufficient support, and the inspection cover 2 may still experience slight displacement due to vibration or its own weight. The second pad 62 flips into the third gap 61 through the third hinge 521, filling the gap with its own structural rigidity, forming a rigid support between the third connecting part 6 and the mounting base 1. This support can counteract the positional displacement of the third connecting part 6, prevent the connection from loosening due to the third gap 61, and force the third connecting part 6 to remain in its original assembly position corresponding to the mounting base 1. This, in turn, keeps the inspection cover 2 in its original position as it was when the first hinge 3 was not damaged, making the positioning function of the third connecting part 6 more reliable in place of the first hinge 3.

[0101] Please see Figure 12 and Figure 13 In some embodiments of this application, the third connecting part 6 is provided with a second connecting hole 65 for the second connector to pass through, and the third connecting part 6 can be connected to the mounting base 1 through the second connector; the second pad 62 is provided with a second relief groove 64, and when the second pad 62 is flipped into the third gap 61, the position of the second connecting hole 65 is opposite to the second relief groove 64, so that the second pad 62 can be supported at least on both sides of the second connector.

[0102] The third connecting part 6 is detachably connected to the mounting base 1 via the second connecting member. The second connecting member needs to pass through the second connecting hole 65 on the third connecting part 6 to complete the assembly, so that the third connecting part 6 can be temporarily fixed after the first folding part 3 is damaged. The second pad 62 is provided with a second clearance groove 64, and the size, shape and position of the second clearance groove 64 have been precisely calculated to form a high fit with the second connecting hole 65 and the second connecting member. When the second pad 62 is flipped around the third folding part 521 into the third gap 61, the position of the second connecting hole 65 corresponds exactly to the second clearance groove 64, so that the second connecting member can be completely accommodated in the space formed by the second clearance groove 64. The second pad 62 will not cause structural interference with the second connecting member, thus not hindering the assembly and fastening of the second connecting member, and can be smoothly embedded into the third gap 61 to achieve close contact with the third connecting part 6 and the mounting base 1.

[0103] Based on this avoidance design, the second pad 62 is stably supported on both sides of the second connector. After the first hinge 3 is damaged, the weight of the third connector 6, external vibration loads, and the impact force generated during dishwasher operation will be concentrated on the second connector and surrounding area. At this time, the second pad 62 supported on both sides can evenly distribute these concentrated loads. This balanced force on both sides can force the third connector 6 to be anchored in its original assembly position corresponding to the mounting base 1, thereby driving the inspection cover 2 to accurately maintain its original position when the first hinge 3 was not damaged, ensuring that the closing accuracy and sealing performance of the inspection cover 2 are not affected, and significantly improving the structural stability and reliability in emergency situations.

[0104] The first pad 52 can also be arranged in a similar manner. Therefore, in some embodiments of this application, the first pad 52 is provided with a first relief groove. When the first pad 52 is flipped into the second gap 51, the position of the first connecting hole 53 is opposite to the first relief groove, so that the first pad 52 can be supported at least on both sides of the first connector.

[0105] The second connecting part 5 is provided with a first connecting hole 53 for the first connecting member to pass through, and can be connected to the mounting base 1 through the first connecting member. The first pad 52 is provided with a first clearance groove. When flipped into the second gap 51, the first connecting hole 53 is opposite to the first clearance groove, so that the first connecting member is placed in the first clearance groove. The center of the first clearance groove is a hollow structure, while the sides are solid structures. Therefore, the first pad 52 can be supported on both sides of the first connecting member, forming a support form with the middle clearance and the sides bearing the load. The first pad 52 is supported on both sides of the first connecting member. Compared with single-point support or offset support, the weight and external pressure of the second connecting part 5 can be more evenly distributed, reducing the deformation of the first pad 52 caused by excessive local stress.

[0106] Similarly, the second pad 62 can also refer to the arrangement of the first pad 52, that is, the number of the second pad 62 is at least two. When the second pad 62 is flipped into the third gap 61, the second pad 62 is provided on at least both sides of the second connecting hole 65 so that the second pad 62 can be supported on at least both sides of the second connector, which can also improve the stability of the second pad 62 support.

[0107] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
