Abstract: A chest ironer having a chest, a cylinder, displacement means for displacement of the chest and the cylinder relatively each other, and rotation means for rotation of the cylinder around an axis of rotation. The chest has a curved metal plate with a concave side which faces the cylinder and a convex side opposite the concave side. The chest ironer further includes at least one induction arrangement for heating of the metal chest. The induction arrangement includes at least one electrical conductor arranged electrically isolated from the chest at the convex side of the chest, the at least one electrical conductor being connectable to a high frequency power source.

Abstract: To control the moisture content of linen leaving a drying ironer, this content is measured by means of a sensor (18). The measurement signal is then transmitted to a variable gain amplifier (30). A circuit (32) automatically adjusts this gain so that the signal leaving the amplifier (30) is non-saturated. This gives instant control of linen moisture content irrespective of the moisture content of the items of linen entering the machine.

Abstract: Method of checking the aseptic nature of washing before opening at least one door of the washing machine. A washing machine (10) is fitted with at least one door (14) capable of being opened into a clean room (20) at the end of each washing-rinsing-spin drying cycle. So as to avoid this opening operation being performed if the conditions for asepsis of the washing are not ensured, opening is conditional on an opening authorization signal being emitted by a control unit (36). This unit checks, successively, the introduction of water into the tank (22) of the machine, the presence in the tank of detergent products, heating of the water to a minimum temperature and the maintainence of this temperature for a predetermined time interval. If any one of these conditions is not fulfilled, the automatic opening signal is not emitted.

Abstract: In a linen or clothes washing machine having a drum (12) with a substantially horizontal axis, which is internally subdivided into two compartments (14a, 14b) by a partition (16) passing through the axis thereof, the drum (12) is rotated at an angular velocity or speed such that the linen (24a, 24b) is subject to a substantially constant radial acceleration with a mean value between approximately 0.70 and 0.95 g, in which g represents the gravitational acceleration. To this end, the system controlling the rotation of the drum (12) preferably includes a closed loop speed control device. An efficient washing is ensured by making the two linen loads (24a, 24b) drop whenever the drum performs a half-turn.

Abstract: To monitor the linen drying in a clothes drier, the residual moisture level of the linen inside the drier is measured and compared to a maximum permissible threshold, which is adjustable and authorization to open the door (14) of the drier is not allowed until the moisture level measured is below said threshold.

Abstract: In a dryer-ironer, the cylinder (10) of which is heated from inside, the cylinder is built so as to define between two concentric walls (18, 22), a closed annular chamber (26) containing a heat carrying fluid. The fluid is set into motion through a stirring system integrated into the cylinder, so that establishment of a uniform temperature may be provided along its entire length. The stirring system may be passive (blades) or active (pump).
