[0034] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0035] The present application provides a door assembly and a dishwasher to solve the problem in the related art that the door adopts a hollow design, resulting in low overall structural strength of the door and easy distortion and deformation of the door when subjected to external force.

[0036] In a first aspect, the present application provides a door assembly, such as Figures 1 to 3 As shown, the door assembly includes a door body 10 , a door body reinforcement 20 and a connecting member 40 .

[0037] Specifically, the door body 10 includes an inner door 11 and an outer door 12 that are arranged opposite to each other. The inner door 11 and the outer door 12 are arranged to form a receiving cavity 13. The receiving cavity 13 can provide installation space for structures such as a distributor and connection line routing.

[0038] The door body reinforcement 20 is arranged in the accommodating cavity 13, and hinge plates 30 are provided at both ends of the door body reinforcement 20. The hinge plates 30 include a first plate body 31 located in the accommodating cavity 13. The door body reinforcement 20 is used to provide support for the inner door 11 and the outer door 12 to enhance the overall structural strength of the door body 10; the hinge plates 30 are used to realize the connection between the door body 10 and the equipment body of household appliances such as dishwashers. The door body 10 is rotatably connected to the equipment body through the hinge plates 30, so that the door body 10 can rotate relative to the equipment body. The specific working principle of the hinge has long been disclosed in the relevant technology and will not be repeated in this application.

[0039] Among them, the connecting member 40 connects the outer door 12, the first plate 31 and the door body reinforcement 20. It should be noted that in the present application, the door body reinforcement 20 can improve the structural strength of the door body 10, thereby improving the door body 10's ability to resist torsion and deformation. At the same time, the outer door 12, the first plate 31 and the door body reinforcement 20 are connected by the connecting member 40, so that the outer door 12, the hinge plate 30 and the door body reinforcement 20 can be fixed as a whole, making the connection between the three more tightly, thereby further improving the structural strength of the door body 10 and preventing the door body 10 from twisting and deforming when subjected to external force.

[0040] In some embodiments, the door reinforcement 20 contacts the inner side 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 door reinforcement 20 more tightly connected to the inner door 11 and the outer door 12, further improving the structural strength of the door 10, and at the same time, when the door 10 is subjected to external impact force, the impact force can be dispersed more quickly on the door body 10 reinforcement strip, further improving the door body 10's ability to resist twisting and deformation. Specifically, the side surface of the door reinforcement 20 facing the inner door 11 contacts the inner side wall of the inner door 11, and the side surface of the door reinforcement 20 facing the outer door 12 contacts the inner side wall of the outer door 12.

[0041] In some embodiments of the present application, the outer door 12 includes a first flange 121, which is located on a side of the first plate 31 away from the door reinforcement 20. A 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 in sequence in a direction close to the accommodating cavity 13, making it easier 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 at the same time, it is unnecessary to provide a hole structure or other connection structure for the connector 40 on 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 (eg, Figure 7 ), the connecting member 40 passes through the first flange 121 and the first plate 31, and is inserted into the threaded hole 211 and threadedly connected to the stud 21. It is understandable that the connecting member 40 can be a threaded connecting member such as a screw or a bolt. The threaded connection between the connecting member 40 and the stud 21 can connect and fix the first flange 121, the first plate 31 and the door reinforcement 20. 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. Among them, the first flange 121 and the first plate 31 can be provided with a through hole 1211 corresponding to the threaded hole 211 on the stud 21, and the connecting member 40 passes through the through hole 1211.

[0043] In some embodiments, the door reinforcement 20 abuts against the first plate 31 to abut the first plate 31 against the first flange 121. It is understandable that by using the door reinforcement 20 to abut the first plate 31 against the first flange 121, the first flange 121, the first plate 31, and the door reinforcement 20 are more tightly connected. At the same time, the door reinforcement 20 can be used to abut the first plate 31 to reduce the shaking of the first plate 31 during use.

[0044] like Figures 4 to 6As shown, in some embodiments of the present 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 inserted into the limiting slot 311. By utilizing the cooperation between the limiting slot 311 and the protrusion 22, a limit can be provided for the door reinforcement 20, and the positioning and installation of the door reinforcement 20 can be realized more conveniently, while the connection strength between the door reinforcement 20 and the first plate 31 can be enhanced.

[0045] Furthermore, the limiting slot 311 extends upward to penetrate one side of the first plate 31 and form an access opening 312. The access opening 312 is used to allow the protrusion 22 to enter and exit the limiting slot 311. It is understandable that when installing the door reinforcement 20, the hinge plate 30 can be first installed on the door body 10. Then, after the door reinforcement 20 is moved above the hinge plate 30 and adjusted to the correct position, the protrusion 22 can be inserted into the limiting slot 311 through the access opening 312. This can achieve the connection between the protrusion 22 and the limiting slot 311, making it easier for the protrusion 22 to be inserted into the limiting slot 311.

[0046] Furthermore, a limiting portion 23 is provided on the protrusion 22. The limiting portion 23 is located at one end of the first plate 31 provided with the access opening 312 and contacts the end face of the first plate 31. It is understandable that the limiting portion 23 can provide a limit and a position reminder for the door reinforcement 20, which can more conveniently achieve 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 access opening 312, and when the limiting portion 23 contacts the end face of the first plate 31, the protrusion 22 cannot move further downward due to the limiting of the limiting portion 23, indicating that the door reinforcement 20 has been installed in place. At this time, the threaded hole 211 on the threaded column is opposite to the through hole 1211 on the first plate 31 and the first flange 121, and the connecting member 40 can smoothly pass through the through hole 1211 and be inserted into the threaded hole 211.

[0047] like Figure 7 As shown, in some embodiments, a first groove 221 is provided on the side of the protrusion 22 facing the first plate body 31, and the stud 21 is provided in the first groove 221 to provide an installation space for the stud 21 through the first groove 221, which can reduce the volume of the end of the door body reinforcement 20, and the stud 21 can be formed on the protrusion 22 by cutting the protrusion 22, so that the formation of the stud 21 is more convenient.

[0048] In some embodiments, a first reinforcement structure 24 is disposed within the first groove 221. The first reinforcement structure 24 is connected to the stud 21 and the inner wall of the first groove 221. The first reinforcement structure 24 can enhance the connection strength between the stud 21 and the bump 22, and can enhance the structural strength of the bump 22, thereby preventing the stud 21 and the bump 22 from twisting and deforming during use. The first reinforcement structure 24 can include a plurality of first reinforcement plates spaced apart around the stud 21, 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 reinforcement structure 26 is provided within the second groove 25 and 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 reinforcement structure 26 can ensure the overall structural strength of the door reinforcement 20, ensuring 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 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 reinforcement structure 26 can be arranged in a grid pattern and can include multiple second reinforcement plates connected to the inner wall of the second groove 25.

[0050] In some embodiments, a second flange 27 is connected to the edge of the door reinforcement 20. The second flange 27 is in contact with 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 body 10, thereby reinforcing more parts of the door body 10 and further improving the structural strength of the door body 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 body 10.

[0051] The second flange 27 is provided with a third reinforcement structure 28 (such as Figure 6 The third reinforcement structure 28 is connected to the second flange 27 and the door reinforcement 20. The third reinforcement structure 28 can enhance the structural strength of the second flange 27 and prevent the second flange 27 from twisting and deformation. The third reinforcement structure 28 can include a plurality of third reinforcement plates arranged at intervals along the length of the door reinforcement 20, and the third reinforcement plates are connected to the second flange 27.

[0052] like Figure 2 and Figure 8 As shown, in some embodiments of the present application, the hinge plate 30 may also include a second plate body 32 and a hinge portion 33. The second plate body 32 is located in the accommodating cavity 13. The second plate body 32 is connected to the first plate body 31 and to the inner side wall 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 body 31. The hinge portion 33 is used to be rotatably connected to the device body of household appliances such as dishwashers to realize the rotatable connection between the door body 10 and the device body.

[0053] Among them, the second plate body 32 can be connected to the inner door 11 by components such as screws or bolts; the first plate body 31, the second plate body 32 and the hinge part 33 can be formed as one piece to improve the overall structural strength of the hinge plate. Of course, according to actual needs, the first plate body 31, the second plate body 32 and the hinge part 33 can also be formed separately and then spliced ​​by welding, clamping, threaded connection or riveting.

[0054] On the second aspect, the present application also provides a dishwasher, which includes a dishwasher body and a door assembly as described in any one of the above embodiments.
