Description

Technical Field

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

[0002] Dishwashers typically connect the inner lid to the main body via hinges. This connection method allows the inner lid to open and close relative to the main body, meeting the daily usage needs of a dishwasher. However, since the hinge structure is usually fixed to the side of the inner lid, and the side of the inner lid is made of a single sheet metal structure with only a simple bending design, its stability is poor. This causes the inner lid to wobble during the opening and closing of the dishwasher door, affecting the user experience. Utility Model Content

[0003] To address the aforementioned technical problem of poor inner cover stability, this utility model provides a dishwasher door assembly and a dishwasher, whose inner cover side is not easily tilted inward or outward, and the overall stability of the inner cover is high.

[0004] The specific technical solution of this utility model is as follows: a dishwasher door assembly includes a hinge and an inner cover for closing the dishwasher body. The inner cover includes a side protruding towards the dishwasher body, a pressing part protruding towards the dishwasher body, and a connecting part disposed between the two. The hinge is fixed to the side and at least partially located between the side and the pressing part. A support member is provided between the hinge and the pressing part. The support member includes a main structure. The side of the main structure near the hinge is pressed against the hinge and is provided with a positioning rib. The positioning rib extends into the gap between the hinge and the connecting part and is clamped by the two. The bottom of the main structure is pressed against the connecting part. An abutting part is provided on the side of the main structure facing the pressing part and near the connecting part. The abutting part abuts against the side of the pressing part facing the side.

[0005] In the above technical solution, the main structure and the abutting part of the support member abut against the hinge and the pressing part respectively, so that the support member is firmly fixed between the two. When the side of the inner cover is subjected to an inward tilting force, the bottom of the main structure abuts against the connecting part, forming a reliable support and preventing the side of the inner cover from tilting inward. The positioning rib fills the gap between the hinge and the connecting part, increasing the equivalent thickness of the connecting part, thereby improving the bending stiffness. When the side is subjected to an outward tilting force, the side drives the hinge to move downward, which is blocked by the positioning rib, limiting the outward expansion deformation of the side. During the opening and closing of the dishwasher door, the side of the inner cover can effectively resist the tilting force in the inward and outward directions, significantly improving the overall stability of the inner cover.

[0006] Preferably, the hinge is fixed to the inner cover by a fixing connector, and a positioning hole is provided at the position corresponding to the fixing connector on the main structure, with the part of the fixing connector that extends out of the inner cover entering the positioning hole.

[0007] In the above technical solution, the fixed connector is embedded in the positioning hole to form a limit and prevent the support from shifting along the side when subjected to external force; relying on the original hinge and inner cover connection structure, the positioning hole is set to strengthen the connection between the support, inner cover and hinge; when the inner cover or hinge is subjected to external force, the fixed connector distributes the external force evenly to the main structure through the positioning hole, thereby enhancing the stability of the overall structure.

[0008] Preferably, the inner cover is connected to the dishwasher body in an openable manner via a hinge, the hinge being fixed to the side end, the side end having an exposed cut edge, and the main structure having a shielding rib to at least partially cover the cut edge.

[0009] In the above technical solution, since the inner cover is a single sheet metal structure, the exposed cut edges are quite sharp. The addition of a shielding rib conceals these edges, preventing users from accidentally touching the sharp edges and getting cut during operation, significantly improving safety and aesthetics. Furthermore, during the dishwasher door opening and closing process, the shielding rib contacts the dishwasher body before the inner cover, preventing deformation damage to easily deformable areas of the inner cover due to direct impact with the body. It also ensures that the dishwasher body is not scratched or damaged by sheet metal parts.

[0010] Preferably, it also includes a first sealing member for compression sealing with the dishwasher body, the inner cover having a U-shaped groove located outside the compression part and extending horizontally, the first sealing member having a plug-in part adapted to the U-shaped groove, the plug-in part being inserted into the U-shaped groove to achieve connection between the first sealing member and the inner cover.

[0011] In the above technical solution, a first sealing element is provided to effectively fill the gap between the inner cover and the dishwasher body, thereby enhancing the sealing performance after the two are connected; the first sealing element can be connected to the inner cover by inserting it into the U-shaped groove, making the connection convenient and quick.

[0012] Preferably, the length of the first sealing element is greater than that of the U-shaped groove, and the main structure is provided with connecting ribs. The connecting ribs extend into the insertion part from the side to realize the connection between the support and the first sealing element.

[0013] In the above technical solution, the connecting rib provides additional support for the first seal, which helps to maintain the shape and position of the first seal during operation.

[0014] Preferably, the main structure is provided with a limiting surface, which is located in the extension direction of the insertion path of the first seal, so as to restrict the first seal from disengaging from the U-shaped groove.

[0015] In the above technical solution, when the first seal tends to detach from the U-shaped groove, the limiting surface will block its movement and firmly constrain the first seal within the U-shaped groove to prevent the first seal from failing.

[0016] Preferably, the end of the first abutting part away from the connecting part is fixedly connected to the main structure, and the end of the first abutting part near the connecting part is suspended relative to the main structure.

[0017] In the above technical solution, the first abutting part is a cantilever beam structure. When the dishwasher opens, closes or operates and vibrates, the suspended end can absorb and disperse the vibration energy by its own elastic deformation, reducing the transmission of vibration to the main structure and other components, and reducing the overall noise and wear of the equipment. When installing the support, even if there is a certain degree of positional deviation or dimensional error, the first abutting part can also adaptively adjust through elastic deformation to avoid installation jamming caused by rigid contact and reduce the difficulty of installing the support.

[0018] Preferably, the end of the first contact part that connects to the main structure is provided with a reinforcing rib connecting the two.

[0019] In the above technical solution, reinforcing ribs are provided to prevent the first contact part from breaking or being damaged due to stress concentration.

[0020] Preferably, the inner cover has two hinges fixed on it, which are symmetrically arranged on the two sides of the inner cover. The extrusion part includes four continuous sides, and each hinge is provided with a support between itself and the corresponding side of the extrusion part.

[0021] In the above technical solution, the symmetrically arranged hinges ensure that the force is evenly distributed during the opening and closing of the inner cover, avoiding tilting or deformation of the inner cover due to force on one side. At the same time, the inner cover, hinges and support components work together to disperse external forces, so that the door assembly can maintain a stable state during frequent use of the dishwasher, thus enhancing the stability of the overall structure.

[0022] Preferably, the system also includes a support rod located outside the extrusion section. The main structure has a snap-fit ​​part adapted to the support rod, and both ends of the support rod snap-fit ​​into the snap-fit ​​part to fix the support rod to the inner cover.

[0023] In the above technical solution, the two ends of the support rod are engaged with the locking parts on the support members. The locking points serve as the fulcrum of the lever. When the side is subjected to an outward tilting force, the two side support members and the support rod form a huge force-reducing lever in the tilting direction, thereby enhancing the anti-outward tilting ability of the inner cover side. At the same time, the support rod, with its own rigidity and tight connection with the support members, forms a stable support frame, restricting the inward deformation of the inner cover and improving the anti-inward tilting performance of the inner cover side. In addition, when the corner of the inner cover is subjected to an impact force, such as when the equipment falls during transportation, the support rod can transmit the impact force to the opposite side support member to protect the inner cover.

[0024] Another specific technical solution of this utility model is: a dishwasher, including a body with an outward opening and the above-mentioned door assembly, and an inner cover connected to the body in an opening and closing manner by a hinge.

[0025] Compared with the prior art, the present invention has at least the following advantages:

[0026] (1) High stability: When the inner cover side is subjected to an inward tilting force, the bottom of the main structure of the support component and the connecting part are pressed together to form a reliable support, preventing the inner cover side from tilting inward. When the side is subjected to an outward tilting force, the side drives the hinge to move downward and is blocked by the positioning rib, limiting the outward expansion deformation of the side. In addition, the support rod is set to build a double protection system. When facing a large deformation force, it forms a stable support frame by its own rigidity and close connection with the support component, limiting the inner cover to deform inward. The two side support components and the support rod form a huge force-consuming lever in the tilting direction, thereby enhancing the anti-outward tilting ability of the inner cover side.

[0027] (2) High safety: Since the inner cover side is a single sheet metal structure, the exposed cut edge is relatively sharp. The cut edge is covered by a shielding rib to prevent users from accidentally touching the sharp edge during operation and causing cuts, which significantly improves the safety of use.

[0028] (3) Good sealing performance: The first sealing element is set to effectively fill the gap between the inner cover and the dishwasher body, which enhances the sealing performance after the two are connected. The connecting rib provides additional support for the first sealing element, and the limiting surface prevents its movement to avoid failure of the first sealing element.

[0029] (4) Impact resistance: When the corners of the inner cover are subjected to impact force, such as when the equipment falls during transportation, the support rod can transfer the impact force to the opposite support to protect the inner cover. Attached Figure Description

[0039] The present invention will be further described below with reference to embodiments. Unless otherwise specified, all devices, connection structures, and methods involved in this invention are known in the art.

[0040] It should be noted that 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. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0041] Example 1

[0042] Reference Figures 1 to 8 As shown, this utility model provides a dishwasher door assembly, including a hinge 1 and an inner cover 2 for closing the dishwasher body 9. The inner cover 2 and the dishwasher body 9 are connected by the hinge 1. The inner cover 2 includes a side 4 protruding towards the dishwasher body 9, a pressing part 6 protruding towards the dishwasher body 9, and a connecting part 5 disposed between the two. The side of the inner cover 2 adopts a single sheet metal structure with an outward "7"-shaped bend design. A connecting support piece 24 is provided on the hinge 1. The connecting support piece 24 is located between the side 4 and the pressing part 6 and is in contact with the side of the side 4 facing the pressing part 6. The hinge 1 is fixedly connected to the side 4 through the connecting support piece 24. A support member 3 is provided between the hinge 1 and the pressing part 6.

[0043] like Figure 3 and Figure 6 As shown, the support member 3 includes a main structure 10. The side of the main structure 10 near the hinge 1 is pressed against the hinge 1 and is provided with a positioning rib 13. The positioning rib 13 extends into the gap between the connecting support piece 24 and the connecting part 5 and is clamped by the two. The bottom of the main structure 10 is pressed against the connecting part 5. The side of the main structure 10 facing the pressing part 6 and near the connecting part 5 is provided with an abutting part 16. The abutting part 16 presses against the side of the pressing part 6 facing the side 4.

[0044] In this embodiment, a rounded transition structure is adopted between the side 4 and the connecting part 5 to reduce stress concentration. During the opening and closing of the dishwasher door, the inner cover 2 is subjected to various forces. The rounded transition can make the force transmission more even, reducing the risk of deformation or damage to the inner cover 2. The rounded transition structure between the side 4 and the connecting part 5 in this invention is not limited to the above-mentioned rounded transition structure. In other embodiments, a sloped transition structure is used, achieving essentially the same technical effect.

[0045] In this embodiment, a gap is left between the side of the positioning rib 13 facing the side 4 and the side 4. In another embodiment, the side of the positioning rib 13 facing the side 4 is in contact with the side 4.

[0046] In this embodiment, the main structure 10 has multiple hollowed-out sections to save materials. Furthermore, reinforcing structures can be installed within the hollowed-out areas to enhance the strength of the main structure 10 and prevent a decrease in overall structural rigidity due to the hollowing out. In another embodiment, the main structure 10 is a solid structure for ease of fabrication.

[0047] In this embodiment, the material of the support member 3 is a low-cost formable plastic, or it can be other materials that can play a supporting role, such as metal, wood, foam plastic, etc.

[0048] The connection steps of the above door components are as follows: First, place the support 3 between the hinge 1 and the pressing part 6. The bottom of the support 3 is pressed against the connecting part 5, and the abutting part 16 abuts against the side of the pressing part 6. Then, place the hinge 1. The connecting support piece 24 is placed inside the side 4, and the bottom surface of the connecting support piece 24 presses the positioning rib 13 against the connecting part 5. The connecting support piece 24 is then fixedly connected to the side 4.

[0049] In the aforementioned door assembly, the main structure 10 and the abutment portion 16 of the support member 3 abut against the hinge 1 and the pressing portion 6 respectively, thus firmly fixing the support member 3 between them. When the side 4 of the inner cover 2 is subjected to an inward tilting force, the bottom of the main structure 10 abuts against the connecting portion 5, forming a reliable support and preventing the side 4 of the inner cover 2 from tilting inward. The positioning rib 13 fills the gap between the hinge 1 and the connecting portion 5, increasing the equivalent thickness of the connecting portion 5 and thereby improving the bending stiffness. When the side 4 is subjected to an outward tilting force, the side 4 drives the hinge 1 to move downward, which is blocked by the positioning rib 13, limiting the outward expansion deformation of the side 4. During the opening and closing of the dishwasher door, the side 4 of the inner cover 2 can effectively resist the tilting forces in the inward and outward directions, significantly improving the overall stability of the inner cover 2. Tilting the side 4 inward refers to tilting towards the pressing portion 6, and tilting the side 4 outward refers to tilting away from the pressing portion 6.

[0050] Example 2

[0051] Based on Example 1, such as Figure 8As shown, this utility model provides a dishwasher door assembly. The bottom of the inner cover 2 has an elongated U-shaped groove 23. The U-shaped groove 23 is located outside the pressing part 6 and extends horizontally, parallel to the bottom side 4 of the inner cover 2. A first sealing member 7 for pressing and sealing with the dishwasher body 9 is snapped onto the U-shaped groove 23. The first sealing member 7 has a plug-in part 22 adapted to the U-shaped groove 23. The plug-in part 22 is inserted into the U-shaped groove 23 to achieve the connection between the first sealing member 7 and the inner cover 2. The first sealing member 7 effectively fills the gap between the inner cover 2 and the dishwasher body 9, enhancing the sealing performance after connection. The first sealing member 7 can be connected to the inner cover 2 simply by inserting it into the U-shaped groove 23, making the connection convenient and quick.

[0052] In this preferred embodiment, the width of the U-shaped groove 23 is slightly smaller than the width of the corresponding insertion part of the first seal 7, forming an interference fit. This allows for a certain elastic deformation pressure to be generated after the first seal 7 is installed, ensuring a tight connection between the seal and the inner cover 2. This effectively prevents the seal from loosening or falling off during use, while also enhancing the sealing performance.

[0053] Reference Figure 1 , Figure 7 and Figure 8 Two hinges 1 are fixed on the inner cover 2. The two hinges 1 are symmetrically arranged on the two sides 4 of the inner cover 2 and located at the end near the first seal 7. The pressing part 6 includes four continuous sides, and a support 3 is provided between each hinge 1 and the corresponding side of the pressing part 6. The symmetrically arranged hinges 1 ensure that the inner cover 2 is subjected to uniform force during opening and closing, avoiding tilting or deformation of the inner cover 2 due to force on one side. At the same time, the inner cover 2, hinges 1 and support 3 work together to disperse external forces, so that the door assembly can maintain a stable state during frequent use of the dishwasher, enhancing the stability of the overall structure. In this embodiment, the hinges 1 are symmetrically installed near the bottom of the inner cover 2. When the inner cover 2 flips down to open, and the inner cover 2 closes the dishwasher body 9 along the flip axis, the first seal 7 is pressed against the lower side of the tank to form a seal in the vertical direction. In other embodiments, hinges 1 can be symmetrically arranged on the two sides 4 adjacent to the connecting side or in the middle of the connecting side, allowing the inner cover 2 to flip to the left and right. Hinges 1 can also be arranged on the upper side of the inner cover 2, allowing the inner cover 2 to flip upwards, etc. Regardless of the installation method, the first sealing element 7 is located on the side where the inner cover 2 flips to ensure a sealing effect. The connecting side refers to the side of the inner cover 2 that connects to the dishwasher body 9. In this embodiment, the connecting side is the bottom side of the inner cover 2.

[0054] Reference Figure 1The inner cover 2 is provided with a support rod 8, which is located outside the compression part 6 and above the first sealing element 7. The main structure 10 is provided with a snap-fit ​​part 15 that is adapted to the support rod 8. The two ends of the support rod 8 are snapped into the snap-fit ​​part 15 to fix the support rod 8 to the inner cover 2. The support rod 8 can be a shape that is not easy to bend, such as a Z-shape, a □-shape, or an L-shape. It should be noted that the snap-fit ​​part 15 is adapted to the support rod 8, which means that the snap-fit ​​part 15 can fix the support rod 8 to the inner cover 2. The snap-fit ​​part 15 can be a simple through hole or a groove or protrusion structure that roughly matches the shape of the support rod 8. The two ends of the support rod 8 are engaged with the snap-fit ​​parts 15 on the support member 3. The snap-fit ​​points serve as the fulcrum of the lever. When the side 4 is subjected to an outward tilting force, the two support members 3 and the support rod 8 form a huge force-reducing lever in the tilting direction, thereby enhancing the anti-outward tilting ability of the side 4 of the inner cover 2. At the same time, the support rod 8, with its own rigidity and tight connection with the support member 3, forms a stable support frame, restricting the inward deformation of the inner cover 2 and improving the anti-inward tilting performance of the side 4 of the inner cover 2. In addition, when the corners of the inner cover 2 are subjected to impact force, such as when the equipment falls during transportation, the support rod 8 can transmit the impact force to the opposite support member to protect the inner cover 2.

[0055] Reference Figure 2 , Figure 3 and Figure 6 The hinge 1 is fixed to the inner cover 2 by a fixing connector 21. A positioning hole 11 is provided at the position corresponding to the fixing connector 21 on the main structure 10. The portion of the fixing connector 21 extending out of the inner cover 2 enters the positioning hole 11. The positioning hole 11 can be a smooth hole or a threaded hole, and the fixing connector 21 can be a screw, bolt, nut, etc. The fixing connector 21, embedded in the positioning hole 11, forms a limit, preventing the support 3 from shifting along the side 4 when subjected to external force. Based on the existing connection structure between the hinge 1 and the inner cover 2, the positioning hole 11 strengthens the connection between the support 3, the inner cover 2, and the hinge 1. When the inner cover 2 or the hinge 1 is subjected to external force, the fixing connector 21, through the positioning hole 11, evenly distributes the external force to the main structure 10, enhancing the overall structural stability.

[0056] In this embodiment, the fixing connector 21 is a screw. The side 4 and the connecting support plate 24 are respectively provided with mounting holes for the screw to pass through. The main structure 10 is provided with a positioning hole 11 at the position corresponding to the mounting hole. One end of the screw passes through the mounting hole and enters the positioning hole 11. During connection, the support 3 is first placed between the hinge 1 and the pressing part 6, with the bottom of the support 3 abutting against the connecting part 5, and the abutting part 16 abutting against the side of the pressing part 6. Then, the hinge 1 is placed, and the connecting support plate 24 is placed inside the side 4, with the bottom surface of the connecting support plate 24 pressing the positioning rib 13 against the connecting part 5. The screw is driven into the mounting hole and the positioning hole 11 from the outside in, so that the support 3, the connecting support plate 24, and the side 4 are fixedly connected.

[0057] Reference Figure 4 and Figure 5 The inner cover 2 is connected to the dishwasher body 9 via a hinge 1, which is fixed to the end of the side 4. The end of the side 4 has an exposed cut edge 20, and the main structure 10 has a shielding rib 12 to at least partially cover the cut edge 20. Since the side of the inner cover 2 is a single sheet metal structure, the exposed cut edge 20 is relatively sharp. The shielding rib 12 covers the cut edge 20, preventing users from accidentally touching the sharp edge and getting cut during operation, which significantly improves safety and aesthetics. In addition, during the opening and closing of the dishwasher door, the shielding rib 12 will contact the dishwasher body 9 before the inner cover 2, preventing the easily deformable area of ​​the inner cover 2 from being deformed and damaged due to direct collision with the body 9. At the same time, it can also ensure that the dishwasher body 9 is not scratched or damaged by sheet metal parts.

[0058] Reference Figure 2 and Figure 3 As shown, the length of the first seal 7 is greater than that of the U-shaped groove 23. The main structure 10 is provided with a connecting rib 14, which extends from the side into the insertion part 22 to connect the support 3 and the first seal 7. The connecting rib 14 provides additional support for the first seal 7, which helps to maintain the shape and position of the first seal 7 during operation.

[0059] Reference Figure 8 As shown, the main structure 10 is provided with a limiting surface 17, which is located in the extension direction of the insertion path of the first seal 7, so as to restrict the first seal 7 from disengaging from the U-shaped groove 23. When the first seal 7 tends to disengage from the U-shaped groove, the limiting surface 17 will block its movement and firmly constrain the first seal 7 in the U-shaped groove to avoid failure of the first seal 7.

[0060] Reference Figure 6 As shown, the end of the first abutment 16 furthest from the connecting part 5 is fixedly connected to the main structure 10, while the end of the first abutment 16 closest to the connecting part 5 is suspended relative to the main structure 10, i.e., a gap is left between the abutment 16 and the connecting part 5. The first abutment 16 has a cantilever beam structure. When the dishwasher opens, closes, or operates, generating vibrations, the suspended end can absorb and disperse the vibration energy through its own elastic deformation, reducing the transmission of vibration to the main structure 10 and other components, and reducing the overall noise and wear of the equipment. When installing the support 3, even if there is a certain degree of positional deviation or dimensional error, the first abutment 16 can also adaptively adjust through elastic deformation, avoiding installation jamming caused by rigid contact and reducing the difficulty of installing the support 3.

[0061] In this preferred embodiment, a reinforcing rib 18 is provided at the end where the first abutting part 16 is connected to the main structure 10 to prevent the first abutting part 16 from breaking or being damaged due to stress concentration.

The inner cover 2 is connected to the body 9 via a hinge 1, which is openable and closable. The hinge 1 includes a hinge seat and a hinge arm. A connecting support 24 is provided on the hinge arm, and the connecting support 24 is screwed to the inner cover 2. The hinge arm is hinged to the hinge seat, and the hinge seat is screwed to the body 9. A second seal 19 is provided on the body 9, fixed to the left, top, and right sides of the body 9. When the dishwasher is closed, the pressing part 6 of the inner cover 2 presses against the second seal 19, achieving a seal.

[0064] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, alterations, or equivalent structural transformations made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
