Similarly, the transverse dimension of the bracket body 210 formed by transversely and sequentially splicing the plurality of extension brackets and the fixing bracket 212 can be changed. In one embodiment, the stent body 210 is formed by combining a transversely sequential splicing connection and a longitudinally sequential splicing connection, and the longitudinal size and/or the longitudinal size of the stent body 210 can be changed by changing the size of any one or more of the expansion stents and/or by changing the number of the expansion stents. Namely, in the actual production, the size of the display screen 220 is not changed, and the size of the fixing bracket 212 is not changed, so that the new production is not needed; if the requirements of household appliance door bodies with different sizes are required to be met, the size of any one or a plurality of expansion supports is/are changed, and/or the number of the expansion supports is/are changed. And the splicing connection is easy to disassemble, the structure of the extension bracket is simple, the production flow is short, the replacement cost is low, and the size of the bracket body 210 can be conveniently adjusted.

As shown in fig. 6, the fixed bracket 212 and the plurality of extension brackets are in the same plane toward the outer contour of the glass panel 230 of the display screen assembly 200; as shown in fig. 3, the fixed bracket 212 and the plurality of expansion brackets are in the same plane away from the outer contour of the glass panel 230 of the display screen assembly 200. That is, the front and back surfaces of the bracket body 210 are flat, which is beneficial to the engagement between the bracket body 210 and the door panel body 120 of the foam door body assembly 100 and the adhesion between the glass panel 230 and the bracket body 210.
