Abstract: A dishwasher comprising a projection means having a concentration lens for concentrating a light beam coming from the light source, said concentration lens being external to the door and solidly constrained to a frame that encloses said access opening. The light beam is projected by the lens towards the exterior of the dishwasher. Downstream of the lens, the light beam extends in a substantially horizontal direction. Downstream of the lens, the light beam intersects an imaginary vertical upwards projection of an upper edge (30) of the door (3) considered in the closed position.

Abstract: A washing and drying machine has a treatment tub and comprises: a washing circuit, for drawing liquid from the tub and conveying it back into the tub, having a pump and means for heating the liquid; a drying circuit for extracting air from the tub and conveying it back into the tub, having a first fan, means for dehumidifying the air, and means for heating the dehumidified air; and a heat-pump arrangement having a refrigerating circuit for a refrigerant fluid, which includes a first condenser, a first evaporator, a first lamination valve, and a compressor. The means for heating the liquid comprise the first condenser, and the refrigerating circuit further comprises a second condenser, in series to the first condenser, and a second evaporator. The means for dehumidifying the air comprise the second evaporator, and the means for heating the dehumidified air comprise the second condenser.
