[0034] To make the objectives, technical solutions, and advantages of 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.
[0035] This application provides a door assembly and a dishwasher to solve the problem in the related art where the door body adopts a hollow design, resulting in low overall structural strength of the door body and easy twisting and deformation when subjected to external forces.
[0036] In a first aspect, this application provides a door assembly, as shown in Figures 1 to 3, which includes a door body 10, a door body reinforcement 20, and a connector 40.
[0037] In one embodiment, the door 10 includes an inner door 11 and an outer door 12 disposed opposite to each other. The inner door 11 and the outer door 12 enclose a receiving cavity 13, which can provide installation space for structures such as distributors and connecting lines.
[0038] The door reinforcement 20 is disposed within the accommodating cavity 13. Hinges 30 are provided at both ends of the door reinforcement 20. Each hinge 30 includes a first plate 31 located within the accommodating cavity 13. The door reinforcement 20 is configured to provide support for the inner door 11 and the outer door 12 to enhance the overall structural strength of the door 10. The hinges 30 are configured to connect the door 10 to the appliance body of a household appliance such as a dishwasher. The door 10 is rotatably connected to the appliance body through the hinges 30, thereby allowing the door 10 to rotate relative to the appliance body. The specific working principle of the hinge has been disclosed in related technologies and will not be elaborated upon in this application.
[0039] The connector 40 connects the outer door 12, the first plate 31, and the door reinforcement 20. It should be noted that in this application, the door reinforcement 20 can improve the structural strength of the door 10, thereby enhancing its resistance to torsion and deformation. Simultaneously, the connector 40 connects the outer door 12, the first plate 31, and the door reinforcement 20, allowing them to be fixed together as a single unit, resulting in a tighter connection and further improving the structural strength of the door 10, preventing torsion and deformation when subjected to external forces.
[0040] In some embodiments, the door reinforcement 20 contacts the inner wall of the inner door 11 and the inner side of the outer door 12, which can reduce the gap between the door reinforcement 20 and the inner door 11 and the outer door 12, making the connection between the door reinforcement 20 and the inner door 11 and the outer door 12 tighter. This can further improve the structural strength of the door 10, and at the same time, it can more quickly disperse the impact force on the door 10 reinforcement strip when the door 10 is subjected to external impact force, which can further improve the door 10's resistance to torsion and deformation. In one embodiment, the side of the door reinforcement 20 facing the inner door 11 contacts the inner wall of the inner door 11, and the side of the door reinforcement 20 facing the outer door 12 contacts the inner wall of the outer door 12.
[0041] In some embodiments of this application, the outer door 12 includes a first flange 121, which is located on the side of the first plate 31 away from the door reinforcement 20. The connector 40 connects the first flange 121, the first plate 31, and the door reinforcement 20. It is understood that the first flange 121 can seal the outer edge of the door 10 to prevent dust from entering the accommodating cavity 13 through the gap between the outer door 12 and the inner door 11. The outer door 12 is connected to the first plate 31 and the door reinforcement 20 through the first flange 121. The first flange 121, the first plate 31, and the door reinforcement 20 are arranged sequentially towards the accommodating cavity 13, making it more convenient to connect the first flange 121, the first plate 31, and the door reinforcement 20 through the connector 40. This makes it easier to connect the outer door 12 to the first plate 31 and the door reinforcement 20, and eliminates the need for connecting structures such as holes for the connector 40 to be made in the main structure of the outer door 12.
[0042] In some embodiments, a stud 21 is provided at the end of the door reinforcement 20, and a threaded hole 211 is provided on the stud 21 (as shown in Figure 7). The connector 40 passes through the first flange 121 and the first plate 31, and is inserted into the threaded hole 211 to be threadedly connected to the stud 21. It can be understood that the connector 40 can be a screw or bolt or other threaded connector. The threaded connection between the connector 40 and the stud 21 can connect and fix the first flange 121, the first plate 31 and the door reinforcement 20, and the connection of the first flange 121, the first plate 31 and the door reinforcement 20 is relatively convenient, making the assembly of the door assembly more convenient. The first flange 121 and the first plate 31 can both be provided with through holes 1211 corresponding to the threaded hole 211 on the stud 21, and the connector 40 passes through the through holes 1211.
[0043] In some embodiments, the door reinforcement 20 abuts against the first plate 31 to bring the first plate 31 against the first flange 121. It is understood that by using the door reinforcement 20 to bring the first plate 31 against the first flange 121, the connection between the first flange 121, the first plate 31, and the door reinforcement 20 is made tighter. Simultaneously, the door reinforcement 20 can be used to hold the first plate 31 in place, reducing the shaking of the first plate 31 during use.
[0044] As shown in Figures 4 to 6, in some embodiments of this application, a limiting slot 311 is provided on the side of the first plate 31 facing the door reinforcement 20, and the end of the door reinforcement 20 has a protrusion 22 that inserts into the limiting slot 311. By utilizing the cooperation between the limiting slot 311 and the protrusion 22, the door reinforcement 20 can be limited, which can more conveniently realize the positioning and installation of the door reinforcement 20, and at the same time strengthen the connection strength between the door reinforcement 20 and the first plate 31.
[0045] Furthermore, the limiting slot 311 extends upward to penetrate one side of the first plate 31 and forms an inlet / outlet opening 312, which is configured to allow the protrusion 22 to enter and exit the limiting slot 311. It is understood that when installing the door reinforcement 20, the hinge plate 30 can be installed on the door 10 first, then the door reinforcement 20 can be moved above the hinge plate 30 and its position adjusted. The protrusion 22 can then be inserted into the limiting slot 311 through the inlet / outlet opening 312, thus connecting the protrusion 22 to the limiting slot 311 and making it easier for the protrusion 22 to be inserted into the limiting slot 311.
[0046] Furthermore, a limiting part 23 is provided on the protrusion 22. The limiting part 23 is located at the end of the first plate 31 where the inlet / outlet opening 312 is provided, and it contacts the end face of the first plate 31. It can be understood that the limiting part 23 can provide a limiting and positioning reminder for the door reinforcement 20, and can more conveniently realize the positioning and installation of the door reinforcement 20. When installing the door reinforcement 20, the worker inserts the protrusion 22 into the limiting slot 311 through the inlet / outlet opening 312. When the limiting part 23 contacts the end face of the first plate 31, the limiting part 23 prevents the protrusion 22 from moving further down, which indicates that the door reinforcement 20 has been installed in place. At this time, the threaded hole 211 on the threaded post is opposite to the through hole 1211 on the first plate 31 and the first flange 121, and the connector 40 can smoothly pass through the through hole 1211 and be inserted into the threaded hole 211.
[0047] As shown in Figure 7, in some embodiments, a first groove 221 is provided on the side of the protrusion 22 facing the first plate 31, and a stud 21 is provided in the first groove 221 to provide installation space for the stud 21 through the first groove 221, which can reduce the volume of the end of the door reinforcement 20, and the stud 21 can be formed on the protrusion 22 by cutting or other means, making the formation of the stud 21 more convenient.
[0048] In some embodiments, a first reinforcing structure 24 is provided within the first groove 221. The first reinforcing structure 24 is connected to the stud 21 and the inner wall of the first groove 221. The first reinforcing structure 24 can improve the connection strength between the stud 21 and the protrusion 22, and can also improve the structural strength at the protrusion 22, preventing problems such as twisting and deformation of the stud 21 and the protrusion 22 during use. The first reinforcing structure 24 may include a plurality of first reinforcing plates arranged at intervals around the stud 21, and the first reinforcing plates are connected to the stud 21 and the inner wall of the first groove 221.
[0049] In some embodiments, a second groove 25 is provided on the side of the door reinforcement 20 facing the inner door 11 and / or the side of the door reinforcement 20 facing the outer door 12. A second reinforcing structure 26 is provided within the second groove 25, and the second reinforcing structure 26 is connected to the inner wall of the second groove 25. It should be noted that the provision of the second groove 25 can reduce the material usage and overall weight of the door reinforcement 20, thereby reducing the cost of the door reinforcement 20. At the same time, the second reinforcing structure 26 can ensure the overall structural strength of the door reinforcement 20, so that the door reinforcement 20 has sufficient structural strength. The second groove 25 can be provided only on the side of the door reinforcement 20 facing the inner door 11 or the side of the door reinforcement 20 facing the outer door 12, or the second groove 25 can be provided on both the side of the door reinforcement 20 facing the inner door 11 and the side of the door reinforcement 20 facing the outer door 12. The second reinforcing structure 26 can be mesh-like in its entirety, and the second reinforcing structure 26 can include multiple second reinforcing plates, which are connected to the inner wall of the second groove 25.
[0050] In some embodiments, the edge of the door reinforcement 20 is connected to a second flange 27, which fits against the outer door 12 or the inner door 11. The second flange 27 can increase the contact area between the door reinforcement 20 and the door 10, thereby reinforcing more parts of the door 10 and further improving the structural strength of the door 10. The second flange 27 can be located on the long side of the door reinforcement 20 and extend along the length of the door reinforcement 20 to further increase the contact area between the door reinforcement 20 and the door 10.
[0051] The second flange 27 is provided with a third reinforcing structure 28 (as shown in Figure 6). The third reinforcing structure 28 is connected to the second flange 27 and the door body reinforcing member 20. The third reinforcing structure 28 can improve the structural strength of the second flange 27 and prevent problems such as twisting and deformation of the second flange 27. The third reinforcing structure 28 may include multiple third reinforcing plates arranged at intervals along the length direction of the door body reinforcing member 20, and the third reinforcing plates are connected to the second flange 27.
[0052] As shown in Figures 2 and 8, in some embodiments of this application, the hinge plate 30 may further include a second plate 32 and a hinge portion 33. The second plate 32 is located in the accommodating cavity 13, and is connected to the first plate 31 and the inner sidewall of the inner door 11 to realize the connection between the hinge plate 30 and the inner door 11. The hinge portion 33 extends out of the accommodating cavity 13 and is connected to the first plate 31. The hinge portion 33 is configured to be rotatably connected to the device body of a household appliance such as a dishwasher to realize the rotatable connection between the door 10 and the device body.
[0053] The second plate 32 can be connected to the inner door 11 by screws or bolts; the first plate 31, the second plate 32 and the hinge part 33 can be integrally formed to improve the overall structural strength of the hinge plate. Of course, according to actual needs, the first plate 31, the second plate 32 and the hinge part 33 can also be formed separately and then spliced by welding, snap-fitting, threaded connection or riveting.
