Abstract: A two-step door opening mechanism for an oven is provided. A mechanical button and an electronic button are provided, the oven defining an oven cavity openable and closable by an oven door. A controller is provided. A digital valve, comprising a shaft configured to slide laterally between a first, unlocked position in which the shaft allows inward movement of the mechanical button and a second, locked position in which the shaft blocks the inward movement of the mechanical button. The electronic button, once actuated, is operable to cause the controller to direct the digital valve to move the shaft from the second, locked position into the first, unlocked position to unlock the mechanical button, and the mechanical button, once actuated, is operable to open the door when the shaft is in the first, unlocked position.

Abstract: A two-step door opening mechanism for an oven is provided. The mechanism includes first and second buttons, arranged side-by-side on a front panel of the oven, the oven defining an oven cavity openable and closable by an oven door, the first and second buttons being separately actuatable one after the other for providing two distinct actions to be performed to open the oven door. The first button, once actuated, is operable to unlock the second button, and the second button, once actuated, is operable to open the door when the second button is unlocked.
