Abstract
The artificial fireplace includes an enclosure delimited by a lower wall, an upper wall and a peripheral wall. The peripheral wall includes an opening, a bed of fake embers being disposed inside the enclosure on a base defined by the lower wall. The enclosure is also provided with a projector for an image, in particular animated flames, towards a display screen disposed in the enclosure in a line of sight extending through the opening. The display screen is defined by a transparent glass plate extending between the bed of fake embers and the projector, while forming, in relation to the incident ray emanating from the projector, an angle ranging between 50° and 56°. The projector is defined for broadcasting images, in particular animated flames, through a linear polarized light. The invention also relates to a fireplace unit or stove comprising an artificial fireplace.
