Dryer-ironer with heated ironing cup and heat carrying fluid

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] ...

AI Technical Summary

Benefits of technology

[0014] The machine according to the invention has integrated heating means. It thus benefits from economical advantages and from the excellent cost effectiveness both specific to this type of machine.

[0015] On the other hand, the use of a heat carrying fluid put into circulation by stirring means also integrated into the machine, provides effective diffusion of heat over the entire length of the ironing cup, as in machines using an external boiler.

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.
