A dish-washing machine having a load-bearing structure and a tub as washtub, a front door of the tub being articulated to the load-bearing structure, the machine moreover having a system for extraction of moist air from the tub that comprises a suction assembly and a discharge duct, wherein the suction assembly comprises a fan, in particular a radial fan, having a fan casing housed in which is a centrifugal impeller, the fan casing defining a suction mouth and a delivery section, the suction mouth being in fluid communication with an outlet opening formed in one of an upper wall and a stationary side wall of the tub, wherein the discharge duct has an inlet portion and an outlet portion, the inlet portion being in fluid communication with a delivery section of the fan casing, wherein the suction assembly comprises a box-shaped casing (7a-7b) located within which is the fan casing, the box-shaped casing (7a-7b) being mounted on an outside of the tub on said one of an upper wall and a stationary side wall of the tub and having - an outlet connection that connects the delivery section of the fan casing to the inlet portion of the discharge duct; - a first suction inlet (22, 23), connected to the outlet opening of the tub; and - a second suction inlet, which opens towards the space that surrounds the tub, wherein the suction assembly comprises a first valve arrangement (24-27, 44) controllable for opening and closing the first suction inlet (22, 23), the first valve arrangement (24-27, 44) being in particular configured for opening and closing the first suction inlet (22, 23) upon activation and deactivation of the fan, respectively, and wherein the suction assembly comprises a second valve arrangement (46, 47) controllable for opening and closing the second suction inlet (28, 37), characterized in that the outlet portion of the discharge duct is at a front of the machine, that the first valve arrangement (24-27, 44) includes a first electric actuator within the box-shaped casing (7a-7b) and the second valve arrangement (46, 47) includes a second electric actuator within the box-shaped casing (7a-7b), and that the second valve arrangement (46, 47) comprises a sliding open/close member with a plate-like body having a plurality of first through openings, the sliding open/close member being set up against a wall of the box-shaped casing (7a-7b), which has a plurality of second through openings that form the second suction inlet, the sliding open/close member being linearly displaceable between a closing position, where the first through openings are staggered with respect to the second through openings, and an opening position, where the first through openings are substantially aligned with the second through openings. wherein the suction assembly comprises a fan, in particular a radial fan, having a fan casing housed in which is a centrifugal impeller, the fan casing defining a suction mouth and a delivery section, the suction mouth being in fluid communication with an outlet opening formed in one of an upper wall and a stationary side wall of the tub, wherein the discharge duct has an inlet portion and an outlet portion, the inlet portion being in fluid communication with a delivery section of the fan casing, wherein the suction assembly comprises a box-shaped casing (7a-7b) located within which is the fan casing, the box-shaped casing (7a-7b) being mounted on an outside of the tub on said one of an upper wall and a stationary side wall of the tub and having - an outlet connection that connects the delivery section of the fan casing to the inlet portion of the discharge duct; - a first suction inlet (22, 23), connected to the outlet opening of the tub; and - a second suction inlet, which opens towards the space that surrounds the tub, - an outlet connection that connects the delivery section of the fan casing to the inlet portion of the discharge duct; - a first suction inlet (22, 23), connected to the outlet opening of the tub; and - a second suction inlet, which opens towards the space that surrounds the tub, wherein the suction assembly comprises a first valve arrangement (24-27, 44) controllable for opening and closing the first suction inlet (22, 23), the first valve arrangement (24-27, 44) being in particular configured for opening and closing the first suction inlet (22, 23) upon activation and deactivation of the fan, respectively, and wherein the suction assembly comprises a second valve arrangement (46, 47) controllable for opening and closing the second suction inlet (28, 37), characterized in that the outlet portion of the discharge duct is at a front of the machine, that the first valve arrangement (24-27, 44) includes a first electric actuator within the box-shaped casing (7a-7b) and the second valve arrangement (46, 47) includes a second electric actuator within the box-shaped casing (7a-7b), and that the second valve arrangement (46, 47) comprises a sliding open/close member with a plate-like body having a plurality of first through openings, the sliding open/close member being set up against a wall of the box-shaped casing (7a-7b), which has a plurality of second through openings that form the second suction inlet, the sliding open/close member being linearly displaceable between a closing position, where the first through openings are staggered with respect to the second through openings, and an opening position, where the first through openings are substantially aligned with the second through openings.
