The control-panel assembly (1) for household appliances and the like, includes: an outer dashboard (2), and at least one rigid protecting box (4). The outer dashboard (2) is provided with at least one protruding appendix (7) that sticks out of its rear face (2r) and that has a coupling ridge (7a) provided with a number of consecutive coupling segments (7b) that are tilted relative to one another. The protecting box (4) is provided with a corresponding cap appendix (8) dimensioned for resting onto the top of the protruding appendix (7), and which has at least one coupling portion (8a) which is shaped for stably matching with any one of the consecutive coupling segments (7b) of the coupling ridge (7a) of the protruding appendix (7). This allows a discrete adjustment of the spatial orientation of the protecting box (4) with respect to the rear face (2r) of the outer dashboard (2).
