The RH9000M is a 4-door food showcase refrigerator with separate doors for refrigerator and freezer sections and more storage space in diverse compartments. For optimal user experience and to highlight its 1-step access, an intuitive 4-door design was applied with two doors for each compartment. The doors have a minimalist look to create a simplified and furniture-like impression. The layered door design also distinguishes the front panel from the door itself. The design takes advantage of human haptic memory to achieve greater simplicity.
