The first limiter 3 is arranged corresponding to the side of the rotating shaft 2 facing the opening direction of the slot 11 to limit the rotation shaft 2 from being separated in the opening direction of the slot 11, so as to realize the supporting effect of the first limiter 3 on the rotating shaft 2. The articulated arm 1 supports the first limiter 3 in the opposite direction to the opening direction of the slot 11 to limit the first limiter 3 from being separated in the opening direction of the slot 11. The structure in which the articulated arm 1 applies a force in the opposite direction to the opening direction of the slot 11 to the first limiter 3 can be understood as the supporting structure of the articulated arm 1 on the first limiter 3. The articulated arm 1 supports the rotating shaft 2 through the first limiter 3;

[0033] The second limit member 4 is arranged on the articulated arm 1, and the second limit member 4 is arranged corresponding to the side of the first limit member 3 to limit the first limit member 3 from disengaging in the side direction of the slot 11. The second limit member 4 does not need to support the rotating shaft 2, and the articulated arm 1 cooperates with the second limit member 4 to realize the positioning of the first limit member 3.

[0034] The first limit member 3 is used to support the rotating shaft, and the second limit member 4 does not need to support the rotating shaft 2, thereby reducing the force on the second limit member 4, so that when the dishwasher is dropped or transported, the second limit member 4 is not easy to separate from the articulated arm 1, thereby ensuring the positioning of the rotating shaft 2 by the first limit member 3 and ensuring the structural reliability of the door hinge.

[0037] In some embodiments of the present invention, Figure 5-7As shown, the latch is a limiting groove arranged on the inner wall of the slot 11, and the card is provided with an inclined portion 33 that cooperates with the latch. The setting of the inclined portion 33 is beneficial to increasing the contact area between the latch and the card, and the notification is used to guide the assembly of the card; in this embodiment, first mounting portions 12 are respectively provided on the opposite sides of the inner wall of the slot 11, and having the first mounting portions 12 on both sides is beneficial to improving the installation stability of the first limiting member 3; or, a first mounting portion 12 is provided on one side of the inner wall of the slot 11.

[0038] In some embodiments of the present invention, Figure 2 , 4 As shown in Figures 5, 8 and 9, a buckle position 41 is provided on the second limiting member 4, and the second limiting member 4 is arranged on the hinged arm 1 through the buckle position 41. The arrangement of the buckle position 41 facilitates the installation and disassembly of the second limiting member 4 on the hinged arm 1. In this embodiment, the buckle position 41 is arranged on the first mounting portion 12 of the slot 11 and is located on the outside of the first limiting member 3, that is, the first mounting portion 12 is used to cooperate with the first positioning portion 31 and the buckle position 41 at the same time, and the buckle position 41 limits the side of the first limiting member 3 at the same time. Buckles 41 are respectively provided on both sides of the corresponding slot 11 of the second limiting member 4, or, a buckling groove (not shown in the figure) located outside the first mounting portion 12 and cooperating with the buckle position 41 is provided on the hinged arm 1 or the slot 11, that is, the first mounting portion 12 is only used to cooperate with the first positioning portion 31, and the buckle position 41 is arranged to cooperate with the structural buckling groove.

[0039] In some embodiments of the present invention, Figure 2 , 4 As shown in Figures 5, 8 and 9, a mounting groove 42 is provided between the two sides of the second limiting member 4, and the second limiting member 4 is arranged on the articulated arm 1 through the mounting groove 42, that is, the articulated arm 1 is at least partially inserted into the mounting groove 42, and the two sides of the second limiting member 4 are respectively arranged outside the two sides of the first limiting member 3, so that the first limiting member 3 cannot be detached from any side of the slot 11.

[0040] In some embodiments of the present invention, Figure 2 , 4As shown in Figures 5, 8, and 9, the second limiting member 4 is provided with a limiting platform 43 extending into the slot 11 and used to abut against the side wall of the slot 11. The setting of the limiting platform 43 improves the stability of the second limiting member 4 on the slot 11. In this embodiment, the limiting platforms 43 are respectively provided on both sides of the second limiting member 4, and the limiting platforms 43 are respectively provided on the two opposite inner side walls of the second limiting member 4 corresponding to the slot 11. The limiting platforms 43 are located on the outer side of the first limiting member 3, and the buckle 41 and the limiting platform are respectively provided. The positioning platform 43 is located on the inner wall of the installation groove 42, the buckle position 41 is connected to the limiting platform 43, the limiting platform 43 is close to the center direction of the slot 11, and a reinforcing rib 44 is arranged in the second limiting member 4. The reinforcing rib 44 is located in the installation groove 42. The setting of the reinforcing rib 44 improves the strength of the second limiting member 4. A through groove 45 opposite to the slot 11 is provided on the side of the second limiting member 4. The buckle position 41 and the limiting platform 43 are located outside the through groove 45. The setting of the through groove 45 facilitates the processing of the limiting platform 43.

[0041] In some embodiments of the present invention, Figure 5-7 As shown, the first limiter 3 is provided with a first extension portion 32 in the thickness direction of the slot 11, and the first extension portion 32 abuts against the inner wall of the slot 11. The first extension portion 32 increases the abutment portion between the first limiter 3 and the inner wall of the slot 11, limits the deflection of the first limiter 3 in the slot 11, and improves the stability of the first limiter 3 in the slot 11.
