Definitions

• Drivers receiving space directed carriers whose outward-facing open sides are bridged by means of reinforcing plates, the width of which extends at least over a part of the axial dimensions of the laundry drum and are firmly connected to the outer side regions of the laundry drum shell adjoining the open sides of the laundry carriers.
• Such a laundry drum is known from DE 198 31 274 C1.
• reinforcement plates extend over part of the axial dimension of the laundry drum, preferably in the middle of the drum shell width.
• the reinforcing plates are firmly connected to the outer side regions of the laundry drum jacket adjoining the open sides of the laundry drivers by a plurality of spaced-apart connection points which are produced by the pressure joining process.
• the invention has for its object to design a known laundry drum of the type mentioned so that the requirements for the strength of the laundry drum at spin speeds of over 1200 rpm are met, but on the other hand, the flood holes lost by covering the reinforcing plates on parts of the drum jacket - Win space again.
• the reinforcing plates extend over the entire length of the axial dimension of the laundry drum jacket and are connected to the drum jacket by means of several hollow rivet-like connections on each of the two outer side regions.
• the hollow rivet-like connections are shown as through-joint connections and each consist of a tulip which is deeply drawn outward into the sheet of the drum shell with, behind the edge, a widened and flattened edge reaching into the reinforcing sheet of a hole.
• the sides of the reinforcement plates facing the edges of the drum jacket are included in the rolled or folded seam.
• This embodiment of the invention also enables the reinforcement plates to be fastened to the side edges, so that sheath tensile forces are not bridged into the drivers alone. kender way in the jacket, but can be derived in part on the side edges and the rolled or folded seam in the bottom pane.
• the laundry drum according to the invention in such a way that in the area of the drivers the roller or fold seam follows the circular jacket contour and the drivers by means of their own roller or fold seam on the Edges of a breakthrough in the floor panes similar to the contour of the drivers are connected to these.
• the side edges of the retracted drivers are connected to the base plate and on the other hand the side edges of the reinforcement plates are fastened to the base plates.
• a laundry drum designed according to the invention which is supported on one side by a support star on one of the floor disks, can be stabilized in a particularly advantageous manner, in addition to the above connecting measures, in that the beam ends of the support star are screwed and the contour of the driver contours is matched with the nuts areas close to the jacket of the base plate are connected.
• the roller or fold seams can be clamped between the beam ends of the support star and the nuts. This form of attachment will act on the laundry drum
• the areas of the reinforcement plates lying in the surface line and close to the roll or fold seams are also connected to the nuts. This can happen, for example, in that the reinforcement plates are fastened to the nuts from outside the jacket contour by means of screws.
• the reinforcement plates can improve the scooping effect of the laundry drivers in that the drivers have lye outlet holes in their ridge regions and the reinforcement plates have embossed gills in their regions covering the open sides.
• gills which are already known from the prior art for cladding sheets, significant amounts of alkali can be scooped from the deep areas of the suds container into the drivers, Carry the mel upwards and then pour it onto the laundry through the lye outlet holes.
• the drum jacket is regularly made from a finite sheet metal strip, the ends of which are joined to form a transverse fold seam to produce the cylinder-like shape, which is also suitable for transmitting a portion of the jacket tensile forces.
• one of the reinforcement plates covers such a transverse fold seam of the drum jacket which is located under one of its outer side regions.
• 1 is an external perspective view of part of the drum shell of a laundry drum designed according to the invention

• FIG. 6 shows a section through the rolled or folded seam which detects the base plate, the drum casing and the reinforcing plate, along the section line VI-VI in FIG. 4.
• the drum jacket 1 of a laundry drum partially shown in FIG. 1 contains a driver 2 molded in one piece in the drum jacket and directed towards the laundry receiving space, with lye outlet holes 3 arranged in its ridge area, which are shaped like a tulip like the flood holes 4 in the drum jacket 1. These flood holes are as tight as possible arranged in the entire drum jacket.
• the drum shell 1 is made from a finally long sheet, with its free ends forming a transverse seam
• each driver 2 is assigned a reinforcing plate 6, which bridges the outwardly open side of the associated driver.
• This reinforcing plate is firmly connected on both sides of the driver to the adjoining outer side regions 7 of the drum shell via several connection points.
• the transverse fold seam 5 lies in the one outside area 7 and is covered by the reinforcement plate 6.
• the reinforcing plate 6 lies so close above the transverse seam 5 that it is at the same time protected by the reinforcement plate 6 from bending open, which could arise when strong jacket tensile forces occur.
• the reinforcing plate 6 is thereby tensioned so much that no expansion of the reinforcing plate can act on the connection points with alternating forces that permanently release these connection points when the sheath tensile forces are strong.
• connection points are push-through joints 8, the cross-sectional shape of which is shown in FIG. 2.
• a push-through joint 8 consists of a tulip 9 which is deeply drawn outward into the sheet of the drum casing 1 and which has a widened and flattened edge 11 which engages behind the edge of a hole 10 punched into the reinforcing sheet 6.
• the push-through joint 8 forms a through hole 12, whose diameter 13 corresponds approximately to that of the flood holes 4.
• separate hollow rivets can of course also be used.
• the laundry drum shown in FIG. 1 can, for example, be supported on one side.
• it has, on the side of the laundry drum facing away from the view in FIG. 1, a base plate which is firmly connected to a supporting star, of which only that in FIG. 1
• Beam end 17 can be seen.
• the (preferably three-beam) support star is connected to the bottom plate at its beam ends by a screw 18 and a die-cast body (nut 19), the outer shape of which is adapted to the inner contour of the driver 2.
• the die casting 19 can be connected to the reinforcing plate 6 from the outside of the reinforcing plate by means of a screw 20.
• the base plate 21 is provided at the level of each driver 2 with an opening 22 similar to the contour of the driver.
• the drum jacket 1 and the reinforcing plate 6 are connected to the base plate 21 via the rolled or folded seam 23. Since the jacket sheet 1 in the area of the driver 2 deviates from the jacket line in the direction of the drum interior, the edge of the jacket sheet 1 in the area of the driver 2 is shaped with the edge of the opening 22 to form a further rolled or folded seam 24. 5 and 6 make it clear that the rolled or folded seam 23 in the area of the driver 2 (FIG. 5) only affects the reinforcing plate 6 and the plate of the base plate 21, while in the area along the section line VI - VI (FIG. 6 ) the sheet of the drum casing 1 is also included in the seam 23.
• a pressure casting 19 according to FIG. 1 can also be inserted into the driver 2 here, both with the reinforcing plate 6 as can also be connected to a beam end 17 of a supporting star, which in FIG. 4 lies against the base plate 21 from the front.
• the rolled or folded seam 24 can enter the clamping area between the pressure casting 19 and the beam end 17 of the support star and can be tightened between the two components by tightening the screw 18
