The inventive device is embodied in the form of a chamber-oven for diffusing vapour and saturated hot air which circulate in a closed circuit by natural convection. Said device is embodied in the form of a domestic-use solar energy collecting device provided with a greenhouse whose surface is equal to 1 m2 and produces from 50 to 100 litres / day of distilled water. The device comprises a distillation unit arranged between two furnaces (59′, 79′) in a temperature-controlled container (48′). Said distillation unit comprises 100 flat thin hollow plates having a surface of 20 dm2 by face and an active volume of 200 dm3. The fine and tensioned walls (54) of said plates are provided with a hydrophilic coating (60′) and internal (56′) and inter-plate (58′) spaces. The lower chimney (59′) comprises a greenhouse (118′, 119′) whose bottom is embodied in the form of an impermeable black layer provided with a thin hydrophilic carpet on the rear part thereof. Saturated hot air at a temperature of 80° C. enters inside (56′) hollow plates from bellow and exits from the top at a temperature of 50° C. A high chimney (79′) is provided with a monoblock heat exchanger (84′) which is transversed by a non-potable water to be distilled which, afterwards is spread warm (40° C.) over the hydrophilic coating (60′). During passage through the heat exchanger (84) the air is cooled to 30° C. and moved down by gravity to the inter-plate spaces (58′) and exits therefrom at a temperature of 78° C. The distilled water condensed in the plates and by the heat exchanger is collected and removed. Brine is received in the bottom of the inter-plate space and distributed along the thin hydrophilic carpet of the bottom (122′) of the greenhouse.
