[0002] In order to improve the integrity of kitchen decoration, more and more kitchen appliances such as dishwashers are installed under the countertop in an embedded manner. The display and operation modules of dishwashers in the current domestic market are generally flat or inclined. The flat shape can well adapt to the appearance coordination problem of the dishwasher and kitchen cabinets, but because the dishwasher is located under the countertop, users cannot directly observe the display operation interface and often need to squat or bend down to adjust the viewing angle, which is inconvenient to operate and leads to poor user experience. Although the use of inclined bevel shape solves the problem of inconvenient operation for users, it correspondingly affects the flatness of the appearance of the dishwasher to a certain extent, and it is difficult to solve the problem of the appearance and operation experience of the whole machine and the cabinet.
