Abstract

The invention relates to a lack of glazing wet Waeschestuecke, with rotatably mounted, wound rolls in the form of perforated, connected to a suction hollow cylinder and can be brought into contact with these, heated with high-pressure steam Arbeitsflaechen in the form muldenfoermiger hollow body, in which the heat of the Walzenbewicklungen and used in the interior of the rolls hot exhaust air and / or accumulating in the trough hollow bodies condensate is used for drying the Waeschstuecke. The invention aims at saving energy costs in the event of mangling or a better mangling process, in that the heat of the exhaust air or of the condensate is used more advantageously than hitherto both in terms of heat technology and in terms of glazing technology. This is done by the exhaust air or the condensate for heating the rollers (12-14) in the direction upstream, rotatably mounted hollow cylinder (18), and the Waeschstuecke for predrying on the outer wall of the hollow cylinder fitting and guided partially circulating with this are.

The invention relates to a defect. Smoothing damp laundry, with rotatably mounted, wound rolls 5-tt. Form perforated, connected to a suction hollow cylinder, and - this- brought into contact _s heated with Hochdruckdanipf working surfaces in the form of trough-shaped hollow body, in which the heat at the Walzenbewicklungen and used in the interior of the rolls hot exhaust air and / or accumulating in the trough-shaped hollow body condensate for drying the laundry is used »

The reuse of the hot "exhaust air of the rollers, called Wrasendämpfe called _s takes place in the aforementioned ₉ known shortages U ₆ a, in order to use the generally unused discharged into the outside air useful to use the type of reuse is in several respects'problematisch» The Ifechtrockner (DE-AS 1 166 740), for example, does not lead to an increase in performance of the deficiency, because in this respect, not the conditions at the end but at the beginning of the deficiency are crucial »The Bachtrocicner acts, but also due to its design in particular also negatively on the achieved in the actual lack of smoothness effect of «The free flow of laundry before and after the actual mangling by means of fresh air., Which was heated in a heat exchanger using the exhaust air of the mangle roller (DE-PS 468 074) _s adversely affects the working conditions at the Lack of.

Heat exchanger for further heating already supplied in another heat exchanger heated air "The twice-heated air is supplied with this recent deficiency» as in the aforementioned earlier defect (DE-PS 182 689) 9 the laundry through the tree between the hollow bodies »-

The use of the heat of the condensate to heat air and the use of the heated air to dry the laundry during the course of the smoothing process is neither advantageous in terms of heat treatment or smoothing in many respects. From a thermal point of view, for example, optimal utilization of condensate heat is beneficial at least in the first case (DE-PS 182 689), because a large portion of the heated air is released into the open air as a result of the constantly switched on suction device of the Yialzen. "

Object of the invention

The object of the invention is therefore to save on energy costs in the absence of defects, without affecting the function of the deficiency process »

Presentation of the essence of the invention

The invention is based on the object, a lack of smoothing wet laundry, with rotatably mounted, wound rolls in the form of perforated, connected to a suction hollow cylinder and can be brought into contact with these, heated with high-pressure steam work surfaces in the form

As a result of the design of the defect according to the invention, the heat contained in the exhaust air or in the condensate is substantially greater, both thermally and in terms of glazing technology, and thus more advantageously than the known defects, because the heat is used to heat the rolls Working direction upstream, unperforated hollow cylinder is used and the laundry items on the outer wall of this Ho ls fitting and with this era.
