[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] The drum washing machine involved in this embodiment includes a shell and a door assembly that can be opened and closed on the front side of the shell. The focus of this utility model is the structure of the door assembly. The specific structure of the drum washing machine is the prior art. For details, please refer to the content disclosed in Chinese utility model patent "Door Assembly and Drum Washing Machine" with patent number ZL202320922161.0 (authorization announcement number CN220013123U). It will not be described in detail in this embodiment.

[0023] like Figures 1-4 As shown, the door assembly of the drum washing machine in this embodiment includes a door frame 1 and a glass bowl 2 disposed on the door frame 1. Part of the glass bowl 2 can extend into the drum of the drum washing machine. The glass bowl 2 is constrained on the door frame 1 in a manner that allows it to rotate about its own axis.

[0024] like Figures 2-4 As shown, the door frame 1 is provided with a bracket 3 for the glass bowl 2 to be rotatably mounted. The bracket 3 has an annular wall 31 in the center. The outer periphery of the glass bowl 2 has a flange 21 that can fit against the annular wall 31. The flange 21 on the glass bowl 2 can rotate relative to the annular wall 31. Multiple permanent magnets 4 are arranged circumferentially on the outer side of the annular wall 31. A coil 5 that can interact with the permanent magnets 4 is provided inside the flange 21. In this embodiment, a sealing ring (not shown in the figure) is also provided between the flange 21 and the annular wall 31 to seal the connection between the two.

[0025] The support 3 is also equipped with a rotating shaft 32 located at the center of the annular wall 31 and perpendicular to the glass bowl 2. The glass bowl 2 has a mounting hole 22 for inserting the rotating shaft 32. Since it is inconvenient to drill holes in the glass bowl 2, in this embodiment... Figure 4 As shown, a partition 23 is provided in the center of the glass bowl 2, and mounting holes 22 are provided on the partition 23.

[0026] In addition, to facilitate the installation of the pivot 32, the bracket 3 is also equipped with mounting strips 33 arranged radially around the pivot 32, with the other end of each mounting strip 33 connected to the bracket 3. The bracket 3 and the door frame 1 are respectively provided with corresponding threaded holes, such as... Figure 3 As shown, the bracket 3 has multiple first threaded holes a arranged circumferentially, and the door frame 1 has second threaded holes b that correspond one-to-one with each of the first threaded holes a. That is, the bracket 3 and the door frame 1 can be fixed by fasteners (screws) passing through the first threaded holes a and the corresponding second threaded holes b.

[0027] The surface of the glass bowl 2 is provided with an inclined portion 24 that gradually slopes downward from the inside of the drum of the washing machine to the outside of the drum. In addition, the surface of the glass bowl 2 is provided with a hydrophobic coating.

[0028] In this embodiment, when the coil 5 inside the flange 21 is energized, a magnetic field is generated. The magnetic field generated by the coil 5 interferes with the magnetic poles of the permanent magnet. Since the bracket 3 is fixed on the door frame 1, the glass bowl 2 can rotate around its own axis. Furthermore, during the rotation of the glass bowl 2, due to the change in the shape of the surface of the glass bowl 2 (i.e., the presence of the inclined part 24), the water flow path of the drum washing machine can be changed, making the washing liquid more evenly distributed in the drum.

[0029] In the specification and claims of this utility model, terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of this utility model. However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
