[0026] The first aspect of this application discloses a gate assembly, which in some embodiments combines with Figures 1 to 3 As shown, the door assembly includes a door body 100, a reinforcing member 200, and a door hinge 300. The door body 100 includes an outer door 110 and an inner door 120. The inner door 120 is connected to the inner side of the outer door 110. The reinforcing member 200 is disposed between the outer door 110 and the inner door 120, and the reinforcing member 200, the outer door 110, and the inner door 120 are connected. The door hinge 300 is connected to the inner door 120, and the door hinge 300 is embedded in the reinforcing member 200. In this way, the reinforcing member 200, the door hinge 300, the outer door 110, and the inner door 120 are combined together, the structural strength of the door assembly is strengthened, which helps to improve the stability of the door assembly and reduce the torsional deformation of the inner door 120 and the outer door 110.

[0027] Let's take a dishwasher as an example to explain the door assembly in detail. A dishwasher includes a body and a door assembly. The body forms a washing chamber for accommodating tableware, including but not limited to bowls, plates, cups, pots, knives, forks, and chopsticks. The dishwasher washes the tableware within the washing chamber. One side of the washing chamber is open, and the door assembly can open and close it. When the door assembly is open, tableware can be placed into or removed. When washing the tableware, the door assembly needs to close the washing chamber.

[0028] The door assembly includes a door body 100 and a door hinge 300. The door assembly is connected to the machine body through the door hinge 300, so that the door body 100 can be rotatably set, and the door body 100 can be rotatably opened and closed to the washing chamber.

[0029] The door 100 includes an outer door 110 and an inner door 120. The inner door 120 is connected to the inside of the outer door 110, that is, the inner door 120 is closer to the washing chamber than the outer door 110 to enclose the washing chamber. The outer door 110 is located on the side of the inner door 120 away from the washing chamber. The inner door 120 is located behind the outer door 110 and the outer door 110 is located in front of the inner door 120. Usually, the inner door 120 and the outer door 110 are connected and assembled together by riveting or screwing. There is a certain space between the outer door 110 and the inner door 120 for installing other components.

[0030] The door hinge 300 is connected to the inner door 120 and also to the machine body, thus assembling the door assembly and the machine body. The structure of the door hinge 300 can refer to relevant technologies, and it generally has two rotatable parts, one part of which is connected to the inner door 120 and the other part of which is connected to the machine body. In this way, the door body 100 can rotate relative to the machine body through the door hinge 300. Normally, the front of the washing chamber is open. The door body 100 rotates forward and downward from the closed washing chamber state to switch to the open washing chamber state, and rotates backward and upward from the open washing chamber state to switch to the closed washing chamber state. The door body 100 is generally vertical when the washing chamber is closed and generally horizontal when the washing chamber is open.

[0031] When the user controls the door 100 to rotate, force needs to be applied to the door 100. Since the door hinge 300 is connected to the inner door 120, there is a mutual constraint between the door hinge 300 and the inner door 120. For the inner door 120 and the outer door 110, if the door hinge 300 is only connected to the inner door 120, then there is no mutual constraint between the door hinge 300 and the outer door 110. In this case, the door 100 is prone to twisting and deformation under force, especially the outer door 110. In particular, when the door 100 is subjected to force on one side, the twisting and deformation of the outer door 110 is more serious.

[0032] Therefore, in this embodiment, the door assembly further includes a reinforcing member 200, which is disposed between the outer door 110 and the inner door 120, and the reinforcing member 200, the outer door 110 and the inner door 120 are connected. The door hinge 300 is embedded in the reinforcing member 200. In this way, the outer door 110, the reinforcing member 200, the door hinge 300 and the inner door 120 are combined together, and mutual constraints are generated between the outer door 110, the reinforcing member 200 and the inner door 120, and between the inner door 120 and the door hinge 300, and between the door hinge 300 and the reinforcing member 200. This improves the overall structural strength of the door assembly, thereby enhancing the stability of the door assembly and reducing the torsional deformation of the inner door 120 and the outer door 110 when the door body 100 is subjected to force.

[0033] Furthermore, the embedding of the door hinge 300 into the reinforcing member 200 facilitates the assembly of the door components. For example, the reinforcing member 200 can be assembled with the outer door 110 first, and the door hinge 300 can be assembled with the inner door 120 first. Then, the outer door 110 and the inner door 120 can be assembled together, and the door hinge 300 can be embedded into the reinforcing member 200 during the assembly of the outer door 110 and the inner door 120.

[0034] It is understandable that the door hinge 300 being embedded in the reinforcing member 200 means that at least a portion of the door hinge 300 is inserted into or extends into the interior of the reinforcing member 200. For example, the reinforcing member 200 may have a limiting groove 240, into which the door hinge 300 is embedded. In this way, the reinforcing member 200 can restrict the door hinge 300, thereby improving structural stability. The door hinge 300 can either have a clearance fit or an interference fit with the limiting groove 240. The former makes it easier for the door hinge 300 to be embedded in the limiting groove 240 during the assembly of the door assembly, while the latter is more conducive to improving the overall structural strength of the door assembly.

[0035] Optionally, the reinforcing member 200 can be a one-piece molded structure. For example, the reinforcing member 200 is made of plastic and is integrally molded through processes such as injection molding and compression molding. It has high structural strength and lays the foundation for improving the rigidity of the door assembly.

[0036] Typically, door components have door hinges 300 on both the left and right sides. Therefore, each side of the door component has a corresponding reinforcing member 200. Specifically, the left side of the door body 100 has both a reinforcing member 200 and a door hinge 300, and the right side of the door body 100 has both a reinforcing member 200 and a door hinge 300. The reinforcing members 200 and the door hinges 300 on both sides can be mirror-symmetrically arranged. The reinforcing members 200 corresponding to the door hinges 300 minimize the space occupied between the outer door 110 and the inner door 120, thus avoiding interference with the installation of other components.

[0037] Optionally, the reinforcing member 200, the outer door 110, and the inner door 120 can be connected by a first fastener 410. The first fastener 410 provides constraint and fixation between the reinforcing member 200, the outer door 110, and the inner door 120, thus reducing the number of first fasteners 410 and simplifying the connection structure between them. It is understood that the first fastener 410 includes, but is not limited to, screws, bolts, rivets, etc. (The same applies to the second fastener 420 described below).

[0038] In some embodiments, combined with Figure 1 As shown, the first fastener 410 is adapted to pass through the inner door 120, the outer door 110, and the reinforcing member 200 to connect the reinforcing member 200, the outer door 110, and the inner door 120, thus preventing the first fastener 410 from being exposed on the outer door 110. For example, the first fastener 410 is a screw. The first fastener 410 first passes through the fastening hole on the inner door 120, and then connects to the outer door 220 and the reinforcing member 200, realizing the connection of the reinforcing member 200, the outer door 110, and the inner door 120. When the door assembly is in the closed state, the first fastener 410 can be hidden.

[0039] In some embodiments, combined with Figures 1 to 7 As shown, the reinforcing member 200 includes a first connecting part 210 and a second connecting part 220. The first connecting part 210, the outer door 110 and the inner door 120 are adapted to be connected by a first fastener 410. The second connecting part 220 is connected to the outer door 110. The first connecting part 210 and the second connecting part 220 are arranged alternately.

[0040] Since the reinforcing member 200 is located between the outer door 110 and the inner door 120, to facilitate the assembly of the outer door 110, the reinforcing member 200, and the inner door 120, the reinforcing member 200 includes a second connecting portion 220. The second connecting portion 220 allows for pre-assembly of the reinforcing member 200 and the outer door 110, thus facilitating subsequent assembly of the outer door 110 and the inner door 120. The reinforcing member 200 also includes a first connecting portion 210. The connection between the reinforcing member 200 and the inner door 120 and the outer door 110 is based on the first connecting portion 210. Based on the pre-assembly of the reinforcing member 200 and the outer door 110, the corresponding positions of the first connecting portion 210 and the outer door 110 correspond to the corresponding positions of the inner door 120, thus facilitating the connection of the first connecting portion 210, the outer door 110, and the inner door 120 via the first fastener 410.

[0041] In some embodiments, combined with Figure 7 As shown, the first connecting portion 210 and the second connecting portion 220 are arranged alternately along the height direction of the door assembly. With the door assembly in the closed state as a reference, the first connecting portion 210 and the second connecting portion 220 are arranged alternately in the vertical direction, which helps to improve the installation stability of the reinforcing member 200, thereby improving the structural strength of the door assembly.

[0042] The first fastener 410 includes, but is not limited to, screws, bolts, rivets, etc. Taking the first fastener 410 as a screw as an example, the first connecting part 210 is a fastening hole, the outer door 110 and the inner door 120 respectively have corresponding fastening holes, and the first fastener 410 passes through the aforementioned fastening holes to be screwed and fastened. In this way, the reinforcement 200, the outer door 110 and the inner door 120 are constrained to each other. The screw can provide a large clamping force to ensure the stability of the connection.

[0043] The connection between the second connecting part 220 and the outer door 110 can be achieved by a snap-fit ​​connection, which enables quick assembly and positioning between the second connecting part 220 and the outer door 110.

[0044] In some embodiments, combined with Figures 8 to 10As shown, the outer door 110 includes an outer panel 111, a first side protrusion 112 disposed on the outer panel 111, and a first side flange 113 connected to the first side protrusion 112. The first side protrusion 112 protrudes from the outer panel 111 toward the inner door 120. The first side flange 113 is opposite to the outer panel 111. The reinforcing member 200 is embedded in the first mounting space 117 surrounded by the outer panel 111, the first side protrusion 112, and the first side flange 113. The first connecting part 210, the first side flange 113, and the inner door 120 are adapted to be connected by a first fastener 410.

[0045] The outer panel 111 constitutes most of the surface of the outer door 110, and is provided with a first side protrusion 112 and a first side flange 113. The first side protrusion 112 protrudes from the outer panel 111 toward the inner door 120, and the first side flange 113 is opposite to the outer panel 111. Thus, the first side protrusion 112 and the outer panel 111 are basically perpendicular, and the first side flange 113 and the outer panel 111 are basically parallel. The first side protrusion 112 and the first side flange 113 form an "L" shape. The outer panel 111, the first side protrusion 112 and the first side flange 113 enclose a certain space (first installation space 117). When the reinforcing member 200 is assembled with the outer door 110, the reinforcing member 200 needs to be embedded into the first installation space 117. At this time, the first connecting part 210 is also embedded into the first installation space 117. The first connecting part 210, the first side flange 113 and the inner door 120 are connected by the first fastener 410. For example, the first fastener 410 is a screw, the first connecting part 210 is a fastening hole with internal threads, the first side flange 113 and the inner door 120 each have corresponding fastening holes, the first fastener 410 can pass through the inner door 120 and the first side flange 113 in sequence and be screwed onto the first connecting part 210. In this way, the mutual constraint and fixation between the reinforcing member 200, the outer door 110 and the inner door 120 can be achieved, and the first fastener 410 can be avoided from being exposed on the outer door 110, thus reducing the number of screws.

[0046] With reinforcement members 200 and door hinges 300 respectively provided on the left and right sides of the door body 100, the left and right sides of the outer panel 111 each have a first side protrusion 112. The first side protrusion 112 is provided with a first side flange 113. The first side protrusion 112 on the left and right sides protrudes from the outer panel 111 toward the inner door 120. The first side flange 113 on the left side extends to the right from the first side protrusion 112 on the left side, and the first side flange 113 on the right side extends to the left from the first side protrusion 112 on the right side.

[0047] In some embodiments, combined with Figures 8 to 10As shown, the outer door 110 also includes a first bottom protrusion 114 disposed on the outer panel 111 and a first bottom flange 115 connected to the first bottom protrusion 114. The first bottom protrusion 114 protrudes from the outer panel 111 toward the inner door 120. The first bottom flange 115 is opposite to the outer panel 111. The reinforcing member 200 is embedded in the second mounting space 118 surrounded by the outer panel 111, the first bottom protrusion 114 and the first bottom flange 115, and the second connecting part 220 is snapped together with the first bottom flange 115.

[0048] The first bottom protrusion 114 protrudes from the outer panel 111 toward the inner door 120, and the first bottom flange 115 is opposite to the outer panel 111. Thus, the outer panel 111, the first bottom protrusion 114, and the first bottom flange 115 enclose a certain space (the second installation space 118). When the reinforcing member 200 and the outer door 110 are assembled, the reinforcing member 200 needs to be embedded into the second installation space 118, and the second connecting part 220 is also embedded. During this process, the second connecting part 220 and the first bottom flange 115 are snapped together, realizing the rapid pre-assembly of the reinforcing member 200.

[0049] For example, the portion of the reinforcing member 200 embedded in the second mounting space 118 is provided with a spring-loaded latch (the spring-loaded latch is the second connecting part 220), and the first bottom flange 115 is provided with a latching hole 116. When the reinforcing member 200 is embedded in the second mounting space 118, the spring-loaded latch and the latching hole 116 are engaged. Since the reinforcing member 200 is also embedded in the first mounting space 117, the pre-assembly stability of the reinforcing member 200 and the outer door 110 is improved, which facilitates the subsequent assembly of the outer door 110 and the inner door 120, and also helps to improve the overall structural stability.

[0050] In some embodiments, the outer panel 111, the first side protrusion 112, and the first bottom protrusion 114 abut against the reinforcing member 200, which helps to improve the overall structural stability of the door assembly and further reduce the torsional deformation of the door body 100. For example, the reinforcing member 200 includes a side rib 250, which is embedded in the first mounting space 117 and abuts against the first side protrusion 112, improving the side structural stability of the outer door 100. The first connecting portion 210 is adjacent to the side rib 250, strengthening the structural strength of the first connecting portion 210 and making it less prone to cracking. The reinforcing member 200 includes a bottom edge 260, which is embedded in the second mounting space 118 and abuts against the first bottom protrusion 114, improving the bottom structural stability of the outer door 100.

[0051] Optionally, the outer panel 111, the first side protrusion 112, the first side flange 113, the first bottom protrusion 114, and the first bottom flange 115 are integrally formed. For example, if the outer door 110 is made of metal, the outer panel 111, the first side protrusion 112, the first side flange 113, the first bottom protrusion 114, and the first bottom flange 115 are formed on the same sheet metal part through processes such as bending, which is more conducive to the manufacturing of the outer door 110.

[0052] In some embodiments, combined with Figures 4 to 12 As shown, the inner door 120 includes an inner panel 121, a second side protrusion 124 disposed on the inner panel 121, and a second side flange 125 connecting the second side protrusion 124. The second side protrusion 124 protrudes from the inner panel 121 toward the outer door 110. The second side flange 125 intersects with the second side protrusion 124 and extends outward from the second side protrusion 124. The second side protrusion 124 is connected to the door hinge 300. The first fastener 410 passes through the second side flange 125 and the first side flange 113 in sequence and is connected to the first connecting part 210.

[0053] The inner panel 121 constitutes most of the surface of the inner door 120. The second side protrusion 124 protrudes from the inner panel 121 toward the outer door 110, providing an installation base for connection with the door hinge 300. The door hinge 300 can be fitted against the second side protrusion 124 to be connected and assembled together. The second side flange 125 intersects with the second side protrusion 124 and extends outward from the second side protrusion 124, thus avoiding interference with the door hinge 300. When the outer door 110 and the inner door 120 are assembled, the second side flange 125 and the first side flange 113 are fitted together. For example, the first fastener 410 is a screw. The first fastener 410 can pass through the second side flange 125 and the first side flange 113 in sequence and be screwed to the first connecting part 210, thus achieving fastening between the inner door 120, the outer door 110 and the reinforcing member 200, reducing the number of screws, and the first fastener 410 can be hidden when the door assembly is closed.

[0054] With reinforcement members 200 and door hinges 300 respectively provided on the left and right sides of the door body 100, the left and right sides of the inner panel 121 each have a second side protrusion 124. The second side protrusion 124 is provided with a second side flange 125. The second side protrusion 124 on the left and right sides protrudes forward from the inner panel 121 toward the outer door 110. The second side flange 125 on the left side extends to the left from the second side protrusion 124 on the left side, and the first side flange 113 on the right side extends to the right from the second side protrusion 124 on the right side.

[0055] Optionally, the inner panel 121, the second side protrusion 124, and the second side flange 125 are integrally formed. For example, if the inner door 120 is made of metal, the inner panel 121, the second side protrusion 124, and the second side flange 125 can be formed on the same sheet metal part through processes such as bending, which is more conducive to the manufacturing of the inner door 120.

[0056] In some embodiments, combined with Figure 4 and Figure 12 As shown, the inner panel 121 has a boss 122 protruding towards the outer door 110. A receiving groove 126 is formed between the boss 122 and the second side protrusion 124. The reinforcing member 200 includes a raised portion 230, which is embedded in the receiving groove 126. The raised portion 230 is provided with a concave surface 231. The edge of the boss 122 forms a stepped portion 123, which is embedded in the concave surface 231 so that the reinforcing member 200 abuts against the inner panel 121.

[0057] The protrusion 122 on the inner panel 121 protrudes towards the outer door 110. In this way, the position of the protrusion 122 on the side of the inner panel 121 facing the washing chamber can avoid the tableware placed in the washing chamber, which is equivalent to increasing the space of the washing chamber. Based on this, a receiving groove 126 is formed between the protrusion 122 and the second side protrusion 124. The reinforcing member 200 is embedded in the receiving groove 126, and the raised part 230 is provided with a concave surface 231. The edge of the protrusion 122 forms a step part 123, which is embedded in the concave surface 231, so that the reinforcing member 200 abuts against the inner panel 121. This enhances the structural stability between the reinforcing member 200 and the inner door 120 and further reduces the torsional deformation of the door body 100.

[0058] In some embodiments, combined with Figure 8 and Figure 12 As shown, the door hinge 300 and the inner door 120 are adapted to be connected by a second fastener 420; The central axes of the first fastener 410 and the second fastener 420 intersect.

[0059] In this embodiment, the first fastener 410 and the second fastener 420 are both threaded fasteners, including but not limited to screws and bolts. The first fastener 410 passes through the second side flange 125 and the first side flange 113 from back to front and is screwed to the first connecting part 210, thus completing the connection and fastening of the reinforcing member 200, the outer door 110 and the inner door 120. The second fastener 420 passes through the second side flange 124 in the left-right direction and is screwed to the door hinge 300, thus completing the connection and fastening of the door hinge 300 and the inner door 120. By setting the central axes of the first fastener 410 and the second fastener 420 to intersect, the structural arrangement is more reasonable. Furthermore, the first fastener 410 and the second fastener 420 with their central axes intersecting can generate constraints in different directions, further improving the structural stability of the door assembly and helping to suppress the torsional deformation of the door body 100.

[0060] The second aspect of this application discloses a dishwasher. In some embodiments, the dishwasher includes a body and the aforementioned door assembly. The door assembly is used to open and close the washing chamber of the body. The door assembly includes a door body 100, a reinforcing member 200, and a door hinge 300. The door body 100 includes an outer door 110 and an inner door 120. The inner door 120 is connected to the inner side of the outer door 110. The reinforcing member 200 is disposed between the outer door 110 and the inner door 120. The reinforcing member 200, the outer door 110, and the inner door 120 are connected by a first fastener 410. The door hinge 300 is connected to the inner door 120 and is embedded in the reinforcing member 200. In this way, the reinforcing member 200, the door hinge 300, the outer door 110, and the inner door 120 are combined together, thereby strengthening the structural strength of the door assembly, helping to improve the stability of the door assembly, and reducing the torsional deformation of the inner door 120 and the outer door 110. It is understood that the door assembly of the dishwasher in this embodiment adopts the technical solution of the above embodiment, and therefore has at least the beneficial effects brought about by the technical solution of the above embodiment, which will not be repeated here.
