[0054] In view of the shortcomings of the prior art, this embodiment provides a door assembly and a dishwasher, which can be specifically referred to as follows:

[0055] As attached Figure 1 , Attachment Figure 5 , Attachment Figure 6 and attached Figure 7As shown, a door body assembly includes a door shell 1, a plurality of T-shaped ears 2, a panel bracket 3 and a plurality of positioning holes 32; the door shell 1 has a accommodating space inside, a slot hole 11 is arranged on the surface of the door shell 1, the slot hole 11 is connected with the accommodating space, and a flange 12 facing the accommodating space is arranged on the inner wall of the slot hole 11, the flange 12 is in a ring shape, and the flange 12 is perpendicular to the surface of the door shell 1; a plurality of T-shaped ears 2 are arranged at intervals on the side wall of the flap, and the short side ends of the T-shaped ears 2 are connected to the side wall of the flap; a panel bracket 3 is arranged in the accommodating space, and a positioning groove 31 is arranged on the side of the panel bracket 3 close to the slot hole 11 of the door shell 1, the positioning groove 31 is in a ring shape, the positioning groove 31 cooperates with the flange 12, and the panel bracket 3 close to the slot hole 11 An inclined placement groove 33 is provided on one side, and the inclined surface of the inclined placement groove 33 is used to place a panel 34, and the panel 34 corresponds to the slot hole 11, so that the panel 34 can be seen or operated in the slot hole 11; a plurality of positioning holes 32 are provided inside the positioning groove 31, and the opening direction of the positioning holes 32 is perpendicular to the inner wall of the positioning groove 31, so that the T-shaped ear 2 can be inserted into the positioning hole 32, and the long side end of the T-shaped ear 2 protrudes from the other side wall of the panel bracket 3; by rotating the T-shaped ear 2, the side wall of the T-shaped ear 2 is abutted against the side wall of the positioning hole 32, and the side wall of the long side end of the T-shaped ear 2 is abutted against the side wall of the panel bracket 3, so that the positioning groove 31 only abuts on the flange 12, and the panel bracket 3 is connected to the door shell 1.

[0056] Specifically, the present application can perform quick positioning through the positioning groove 31 and the flap, and the T-shaped ear 2 can be inserted into the positioning hole 32, and then the side wall of the T-shaped ear 2 can be abutted against the positioning hole 32 and the side wall of the panel bracket 3 by rotating the T-shaped ear 2, thereby achieving the fixation of the panel bracket 3; compared with the prior art, which requires the groove and the protrusion to be positioned by force, the present application can move the panel bracket 3 and the door shell 1 relative to each other, and easily position the positioning groove 31 and the flange 12; compared with the prior art, which also requires the ear piece to be bent and fixed with the fastening mouth, and the ear piece to be flattened, and during use, the panel bracket 3 will squeeze the ear piece to bend, thereby forming a gap between the panel bracket 3 and the ear piece, resulting in abnormal noise, the present application only needs to rotate the T-shaped ear 2 to achieve fixation, and under external vibration, the panel bracket 3 will not be loose, which is simpler and more convenient to operate.
