[0009] In some embodiments, along the thickness direction of the outer door, a projection of the hinge and a projection of the second support member at least partially overlap on the outer door, so that the second support member can fully bear the torsional force.

[0010] In some embodiments, the door body also includes a first connecting portion, which is connected to the outer door and the end of the first support member. The second support member also includes a second connecting portion, which is connected to the ends of the first support member and the second support member.

[0013] In some embodiments, two first positioning members are arranged at an angle to further ensure the stability of the installation of the second support member.

[0014] In some embodiments, the second support member further includes a connecting portion connected to the first support portion and the second support portion, and the third connecting portion has a plurality of steps connected in sequence; wherein two adjacent steps are connected by a first arc transition to reduce stress concentration at the corner of the second support member.

[0015] In some embodiments, some of the steps are provided with avoidance grooves for avoiding the hinges to ensure normal opening and closing of the door body.

[0016] In some embodiments, at least a portion of the steps are provided with markings to facilitate installation of the second support member.

[0017] In some embodiments, a plurality of grooves are provided on the third connecting portion to achieve weight reduction.

[0018] In some embodiments, the third connecting portion defines a cavity, and the second supporting member further includes: a plurality of reinforcing portions, which are arranged in parallel and spaced apart in the cavity and are respectively connected to the first supporting portion, the second supporting portion and the third connecting portion to improve the structural strength of the second supporting member.

[0019] In some embodiments, the outer door and the first support member are connected via a second arc transition, and the first support portion and the second support portion are connected via a third arc transition; wherein the radius of the second arc is smaller than the radius of the third arc to facilitate the installation of the second support member.

[0044] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0045] The dishwasher provided in this embodiment is intended to at least solve the technical problem of low torsional strength of the door body to a certain extent.

[0046] Figure 1 A front view of a door body of some embodiments; Figure 2 for Figure 1 Exploded view of the middle door body; Figure 3 for Figure 1 Schematic diagram of the assembly of the second support member of the middle door body and the outer door; Figure 4 for Figure 1 Schematic diagram of the arrangement of the second support member and the hinge member of the middle door body. Figure 1 , Figure 2 , Figure 3 and Figure 4 The door body of the embodiment of the present application includes: an inner door 10, an outer door 20, a first support member 30, a second support member 40 and a hinge member 50. The outer door 20 is connected to the inner door 10. The first support member 30 is connected to the outer door 20 at an angle. The second support member 40 is connected to the outer door 20, and the second support member 40 includes a first support portion 401 and a second support portion 402. The first support portion 401 is attached to the outer door 20, and the second support portion 402 is attached to the first support member 30. The hinge member 50 is connected to the inner door 10.

[0047] The material of the second support member 40 can be one of POM (polyformaldehyde), PBT (polybutyleneterephthalat), PC (Polycarbonate), PA (Polyamide), PPS (Polyphenylenesulphide), and PTFE (Polytetrafluoroethylene).

[0048] Since the outer door 20 is connected to the inner door 10 and the hinge 50 is connected to the inner door 10, the outer door 20 and the inner door 10 form a door body structure, and the opening and closing of the door body structure can be achieved through the hinge 50. Since the first support member 30 is connected to the outer door 20 at an angle and the second support member 40 is connected to the outer door 20, the second support member 40 includes a first support portion 401 and a second support portion 402. The first support portion 401 is in contact with the outer door 20 and the second support portion 402 is in contact with the first support member 30. Therefore, when the door body is opened or closed, the outer door 20 is subjected to a torsional force, and the outer door 20 is deformed and squeezed by the second support member 40. The outer door 20 transmits the torsional force to the first support portion 401, and the first support member 30 transmits the torsional force to the second support portion 402, so that the second support member 40 can bear the torsional force, and the deformation of the outer door 20 can be limited, thereby effectively increasing the strength of the door body, making the door body have high torsional strength, reducing the possibility of deformation of the door body, and bringing a better user experience to the user.

[0049] In some embodiments, the first support member 30 is formed integrally with the outer door 20 , that is, the first support member 30 may be a folded edge of the outer door 20 .

[0050] Combination Figure 1 and Figure 2 In some embodiments, in order to ensure the strength of the door body, the number of the second support members 40 is two, and the two second support members 40 can be relatively arranged on both sides of the outer door 20, and the two second support members 40 and the control panel 70 are relatively arranged at both ends of the outer door 20.

[0051] When the door is opened or closed, the connection between the hinge 50 and the inner door 10 is the main force bearing point. Since the inner door 10 is connected to the outer door 20, the torsional force can be transmitted to the outer door 20. In other words, the position of the outer door 20 close to the hinge 50 is subjected to a large torsional force and is prone to distortion. Figure 1 and Figure 2 In some embodiments, along the thickness direction of the outer door 20, the projection of the hinge 50 and the projection of the second support member 40 at least partially overlap on the outer door 20, so that the second support member 40 can fully bear the torsional force, limit the deformation of the outer door 20, and effectively increase the strength of the door body. The torsional strength of the door body is high, the possibility of deformation of the door body is reduced, and a better user experience is brought to the user.

[0052] Combination Figure 1 and Figure 2 In some embodiments, in order to ensure smooth opening and closing of the door body, the number of hinges 50 is two, and the two hinges 50 are arranged on both sides of the outer door 20 relatively, and the two hinges 50 correspond one by one to the two second support members 40.

[0053] Combination Figure 1 and Figure 2In some embodiments, in order to facilitate the arrangement of the second support member 40, the outer door 20 is arranged perpendicular to the first support member 30, and the second support portion 402 is arranged perpendicular to the first support portion 401. When installing the second support member 40, the first support portion 401 can be directly fitted with the outer door 20 and the second support portion 402 can be fitted with the first support member 30 through the coordination of right angles, thereby improving the installation efficiency.

[0054] In some embodiments, the outer door 20 is perpendicular to the first support member 30, but the vertical relationship between the outer door 20 and the first support member 30 is not absolutely vertical in a geometric sense, and the angular relationship between the outer door 20 and the first support member 30 may be within the range of 90±3°.

[0055] In some embodiments, the second support portion 402 is perpendicular to the first support portion 401 , but the perpendicular relationship between the second support portion 402 and the first support portion 401 is not absolutely perpendicular in a geometric sense, and the angle relationship between the second support portion 402 and the first support portion 401 may be within the range of 90±3°.

[0056] Combination Figure 1 In some embodiments, in order to make full use of the space between the outer door 20 and the first support member 30, the second support member 40 is located between the inner door 10 and the outer door 20. That is to say, the second support member 40 is arranged inside the door body, which can avoid the second support member 40 from occupying the space outside the outer door 20, reduce the size of the door body, and facilitate the arrangement of the door body. At the same time, the second support member 40 can be shielded by the first support member 30, the outer door 20 and the inner door 10 to avoid the second support member 40 being exposed to the outside, thereby ensuring the safety of the second support member 40 and the beauty of the door body.

[0059] In some embodiments, the connecting member 80 may be a self-tapping screw. Of course, in some other embodiments, the connecting member 80 may also be a bolt or a screw, and the second through hole 4031 is a bolt hole.

[0060] In some embodiments, the first connection portion 60 is integrally formed with the outer door 20 , that is, the first connection portion 60 may be a folded edge of the outer door 20 .

[0061] Combination Figure 3 , Figure 5 and Figure 6 In some embodiments, in order to realize a second support member 40 that can be used for installation on the left and right sides of the door body, two second connecting parts 403 are relatively arranged. That is to say, the second support member 40 can be placed on either side of the left or right side of the door body, and the second connecting part 403 can be connected to the first connecting part 60 to realize the connection between the second support member 40 and the outer door 20, which can reduce the manufacturing cost.

At the same time, it also ensures the stability of the installation of the second support member 40, thereby improving the installation efficiency.

[0064] In some embodiments, in order to further ensure the stability of the installation of the second support member 40, two first positioning members 90 are arranged at an angle, and two second positioning members 404 are arranged at an angle. The first positioning member 90 is plugged and connected with the corresponding second positioning member 404, thereby realizing pre-positioning and limiting the second support member 40 in two different directions, ensuring the determination of the installation position of the second support member 40, and at the same time, ensuring the stability of the installation of the second support member 40, thereby improving the installation efficiency.

[0065] In some embodiments, the two second positioning members 404 are perpendicular to each other. However, the perpendicular relationship between the two second positioning members 404 is not absolutely perpendicular in a geometric sense. The angular relationship between the two second positioning members 404 may be within a range of 90±3°.

[0066] In some embodiments, the two first positioning members 90 are perpendicular to each other. However, the perpendicular relationship between the two first positioning members 90 is not absolutely perpendicular in a geometric sense. The angular relationship between the two first positioning members 90 may be within the range of 90±3°.

[0067] In some embodiments, one of the first positioning member 90 and the second positioning member 404 is provided with a slot, and the other can be locked in the slot to achieve plug-in connection between the first positioning member 90 and the second positioning member 404 .

[0068] In some embodiments, when the second positioning member 404 is disposed on the second connection portion 403 and two second positioning members 404 are disposed at an angle, one of the two second positioning members 404 is disposed at the connection between the second connection portion 403 and the first support portion 401, and the other is disposed at the connection between the second connection portion 403 and the second support portion 402, so as to limit the second support member 40 along the thickness direction of the outer door 20 and along the two sides of the outer door 20, thereby ensuring the determination of the installation position of the second support member 40, and at the same time, ensuring the stability of the installation of the second support member 40, thereby improving the installation efficiency. The two second positioning members 404 protrude from the surface of the second connection portion 403 to form a convex ridge.

[0070] In some embodiments, in order to facilitate the arrangement of the second support member 40 , the third connection portion 405 has a plurality of steps 406 connected in sequence.

[0071] Combination Figure 3 , Figure 5 and Figure 6 In some embodiments, in order to reduce stress concentration at the corner of the second support member 40 , two adjacent steps 406 are connected by a first arc transition, which can ensure the structural strength of the second support member 40 .

[0072] In some embodiments, in order to further ensure the structural strength of the second support member 40, the first support portion 401, the second support portion 402 and the third connection portion 405 can be integrally formed, thereby reducing the processing cost.
