Problems solved by technology

On the other hand, they have the drawback that the cup is uniformly heated on its entire length, regardless of the areas where the pieces of laundry are inserted during ironing.
Consequently, the next piece of laundry will be badly ironed if it is inserted in the same area as the previous one or be burnt if it is inserted in a different area.
On the other hand, these machines have the drawbacks of requiring heavy, expensive and complex external facilities.
When several dryers-ironers are placed in a same building, these drawbacks sometimes result in that the users feed these machines with heat carrying fluid simultaneously, from a unique circuit integrating a single boiler and a single pump.
However, such facilities are only feasible if several dryers-ironers are used simultaneously and they remain more expensive and more complex than facilities using machines with integrated heating.

Embodiment Construction

[0012] Specifically, the object of the invention is a dryer-ironer with heated cup, its original design allows it to benefit both from cost effectiveness and cost advantages specific to machines with integrated heating and from the advantages provided by uniform diffusion of heat on the entire length of the cup of machines which are heated through a heat carrying fluid.

[0013] According to the invention, this result is obtained by means of a dryer-ironer comprising an ironing cup in the shape of a cylindrical sector provided with an internal wall, able to come into contact with the laundry to be ironed, and means for heating said wall, characterized in that the cup further comprises an external wall which externally lines, at a distance, the internal wall, directly close to the heating means, so as to delimit with said internal wall, a closed chamber filled with a heat carrying fluid able to transfer heat produced by heating means to the internal wall, and stirring means able to gene...

Abstract

Dryer-ironer with heated ironing cup and heat-carrying fluid. In a dryer-ironer with heated cup (10), the cup is built so as to define a closed chamber (26) containing a heat carrying fluid between two parallel walls (18, 22). The fluid is set -into motion through a stirring system integrated with the cup so as to provide the establishment of a uniform temperature along its entire length.

Description

[0001] The present invention relates to a dryer-ironer wherein the laundry is ironed between a heated ironing cup and a rotating roller.[0002] The dryer-ironer according to the invention may be used in all cases where relatively large amounts of laundry must be frequently ironed. Thus and uniquely as an example, such a machine may be used in hospital institutions, nursing homes, lodging houses, hotels, restaurants, etc.STATE OF THE ART[0003] In dryers-ironers with a cup, ironing of the laundry is performed between a metal ironing cup, in the shape of a cylindrical sector with a generally horizontal axis, and a pressing roller covered with baize, the axis of which coincides with that of the cup and the lower portion of which rests on said cup. When the machine is operating, the pressing roller is driven into rotation around its axis. Consequently, the pieces of laundry to be ironed, inserted between the cup and the roller on one side of the machine, come out on the other side.[0004] ...
