Definitions

  • the invention relates to a device for detaching wallpaper or the like. From a support by means of steam, consisting of a steam generator and a steam plate connected to this via a flexible steam hose for dispensing the steam, the steam generator being able to be filled by a handle provided with a handle Lid lockable boiler and an electric heating element for heating the water contained therein.
  • a wallpaper removal device of this type is known from WO 90/13771.
  • the handle opening of the carrying handle provided for transporting the steam generator, which is integrated in the lid, is separated from the boiler steam space only by an intermediate wall, so that the carrying handle is inevitably heated and burns are sometimes unavoidable when the intermediate wall is touched. Furthermore, there is the risk that the connection between these parts will leak and thus, in particular, when a seal arranged between the boiler and the cover ages hot steam flows out of the boiler, very large. It is also disadvantageous that the hot steam flows out from all sides and thus also in the direction of the handle from the safety valve inserted directly into the lid next to the handle with a corresponding excess pressure in the steam generator.
  • the object of the invention is therefore to improve the device for removing wallpaper of the aforementioned type in such a way that, when used as intended, it is almost impossible for a user of the device to come into contact with heated components or hot steam. Burns and scalds should therefore be reliably avoided, and simple and safe operability and high operational reliability should also be provided. The construction effort required for this should be kept low, but effective protection against injuries caused by hot steam or touching heated parts should always be guaranteed.
  • this is achieved in a device for removing wallpaper of the aforementioned type in that the handle provided on the lid of the steam generator is thermally attached to the lid separately from the lid.
  • the handle thermally separated from the lid by one or more intermediate spaces provided between it and the lid of the steam generator, preferably open on one or both sides, and the handle designed in the form of a bracket over at least two approximately perpendicular to its longitudinal direction Molds on the lid.
  • the carrying handle should also be in the form of an obtuse-angled triangle, the first leg of which is arranged approximately parallel to the outer edge of the lid and extends inward from it, the second leg of which is formed on the end of the first leg and under one of these included obtuse angle protrudes and the third leg is designed as a handle that is connected to the free ends of the first and second legs of the handle.
  • a steam-collecting housing connected to the interior of the boiler on the carrying handle following its second leg, which is triangular in cross-section in the direction of the carrying handle and whose wall facing the carrying handle is parallel to the second leg and with Distance to this should be such that, for thermal separation of the handle from the housing, one or more intermediate spaces, preferably open on one or both sides, are formed between the housing.
  • the wall of the housing facing away from the handle can also be provided with a filler neck which is preferably designed as a connection for the steam hose.
  • the handle with a pressure relief valve, which is preferably interchangeably inserted in its end region diametrically opposite the housing and which can automatically connect the interior of the boiler to the atmosphere and which has an outlet opening directed radially outwards approximately perpendicular to the longitudinal axis of the boiler.
  • a pressure relief valve which is provided between the lid of the kettle and the first leg of the handle, is incorporated into an attachment piece formed on the lid and is covered by the handle.
  • the lid it is also expedient to firmly connect the lid to the wall of the boiler, for example to weld it on, and to provide the boiler and / or the lid in the region of the connection point with an integrally formed circumferential ring or extension arranged at a distance from this .
  • the boiler should be equipped, in whole or in part, on its outer surface with molded-on heat protection ribs arranged at a lateral distance from one another.
  • the heating element of the boiler should be arranged in a conical or U-shaped recess formed in its base.
  • the steam plate that can be connected to the steam generator should consist of a worktop and a handle bracket that is also thermally separated from it.
  • the handle bar is thermally separated from one another by one or more interspaces which are preferably provided on one or both sides and are preferably open by webs.
  • the handle of the steam plate should also be in the form of an obtuse-angled triangle, the first leg of which is arranged approximately parallel to the housing of the worktop and at a distance from it and the second leg on the front and the third leg on the rear end of the first Legs are integrally formed and connected to each other at an obtuse angle, the first leg of the handle bar extending over the axial length of the worktop and the walls of the housing in the front and rear end region should each be designed in the direction of escape of the second and third legs of the handle bar.
  • the handles of the handle formed on the lid and / or the handle formed on the worktop should additionally or partially be provided on the inside with cooling fins preferably formed by recesses, and the handles of the handle and / or molded on the lid should also be provided of the worktop integrally formed in the longitudinal direction wholly or partially convexly curved or in cross-section on the inside wholly or partially convexly curved.
  • the steam hose connecting the steam generator to the steam plate should in each case be releasably connectable to the steam generator and / or the worktop by means of a union nut provided on its outer circumferential surfaces with circumferential or axial directions and provided with heat protection ribs.
  • a device for removing wallpaper according to the invention there is a guarantee that, when used as intended, the components to be touched cannot be heated in an inadmissible manner and that a user will not come into direct contact with heated components. The risk of injury from scalding and / or burning is therefore low. Above all, however, it is ensured that hot steam emerging from the pressure relief valve cannot reach the area of the handle, the pressure relief valve is rather covered by the cover and the hot steam thus flows laterally between it and the boiler. And since the connection of the steam hose is designed as a filler neck, the steam generator is also easy to handle when filling the boiler. With a simple structural design, a device is therefore created which is reliable and easy to use and which, despite the hot medium to be processed, can also be used safely.
  • the device shown in FIG. 1 and designated 1 serves to remove wallpaper or the like from a carrier by means of hot steam and essentially consists of a steam generator 2 and a steam plate 3 for discharging the steam, which are connected to the steam generator via a flexible steam line 4 2 is connected. Due to the hot steam generated in the steam generator 2 emerging from the steam plate 3, the wallpapers are softened and detached from the wall, so that they z. B. can be easily removed with the help of a spatula.
  • the steam generator 2 as can be seen in particular from FIGS. 2 and 3, consists of a boiler 11 and a cover 21 which is firmly connected to the latter and which is provided with an integrated handle 31.
  • a pressure relief valve 41 is used in the cover 21, to which an outlet opening 27, which is covered by the cover 21 and directed radially outwards, is assigned.
  • the steam plate 3 is formed here by a worktop 51 and a handle 61 molded onto it.
  • the boiler 11 of the steam generator 2 has a cylindrical wall 12 and a bottom 13 inserted therein, in which a trough 15 is provided for an electric heating element 16.
  • the heating element 16 can be connected to a power source by means of a plug 17.
  • the boiler 11 is equipped with feet 18, and a ring 19 is formed on the outer surface of the wall 12 at a distance from this.

  • a plurality of interspaces 23, 23 'and 23' 'open on both sides are provided between the cover 21 and the handle 31, which are formed by webs 22, 22' 22 '' and 22 '' 'running perpendicular to the longitudinal direction of the handle 31.
  • an annular peripheral projection 24 is provided on the cover 21, which is aligned with the ring 19 of the boiler 11. The lid 21 can thus be welded to the wall 12 of the boiler 11, but the welded connection is covered by the ring 19 and the neck 24.
  • the handle 31 is in the form of an obtuse-angled triangle and is therefore composed of three legs 32, 33 and 34.
  • the first leg 32 extends from the outer end of the circular cover 21 and at a distance from it radially inward, the second leg 33 is formed on the end of the first leg 32 and protrudes from it at an obtuse angle.
  • the third leg 34 is designed as a handle 34 'and connects the first leg 32 to the second leg 33.
  • the handle 34 ' is convexly curved and provided on the inside with cooling fins 47 created by cutouts 46.
  • a steam collector housing 35 which is permanently connected to the interior 14 of the boiler 11, is formed on the second leg 33.
  • the steam collecting housing 35 is here triangular in cross-section in the direction of the carrying handle 31, and its wall 36 facing the carrying handle 31 runs at a distance from the second leg 33, so that this is also thermally separated from the steam collecting housing 35 by an open space 38 on both sides.
  • the wall 37 of the steam collecting housing 35 facing away from the handle 31, on the other hand, is provided with a filler neck 39 which is designed as a connection for the steam hose 4 and has an external thread 40 for the latter.
  • the pressure relief valve 41 by means of which the interior 14 of the boiler 11 can automatically be connected to the atmosphere at a certain overpressure prevailing therein, consists of a valve body 43 arranged in an insert piece 42 inserted in a recess 28 of the cover 21 and a valve body acting thereon on the insert 42 supporting valve spring 44.
  • the valve body 43 is slidably guided in a projection 25 formed in the cover 21, into which a bore 26 is also machined, so that the pressure prevailing in the interior 14 of the boiler 11 is constantly on the valve body 43 can act.
