         5 . A refrigerator unit and/or a freezer unit in accordance with  claim 1 , wherein a second coil is arranged at the cover or at the door or flap of the unit and that a voltage is only induced in said second coil in one specific position or in a plurality of specific positions of the cover or of the flap or door, preferably with a completely or largely closed cover or with a completely or largely closed door or flap, with the second coil being in communication with the heating device such that a current flow is generated through the heating device by the second coil. 
     
     
         6 . A refrigerator unit and/or a freezer unit in accordance with  claim 1 , wherein a second coil is arranged at the cover or at the door or flap of the unit and that a voltage is induced in it at least regionally independently of the position of the cover or of the door or flap, with the second coil being connected to the heating device such that a current flow is generated through the heating device by the second coil. 
     
     
         7 . A refrigerator unit and/or a freezer unit in accordance with  claim 4 , wherein a cut-out, preferably a groove, is provided at the body of the unit which is surrounded at least partly by the first coil. 
     
     
         8 . A refrigerator unit and/or a freezer unit in accordance with  claim 7 , wherein the unit has a movably arranged cover; and in that the groove of the carcass extends in the direction in which the cover is movable. 
     
     
         9 . A refrigerator unit and/or a freezer unit in accordance with  claim 7 , wherein the unit has a movably arranged cover; and in that the groove of the carcass extends in a direction which extends at an angle, preferably at a right angle, to the direction in which the cover is movable. 
     
     
         10 . A refrigerator unit and/or a freezer unit in accordance with  claim 5 , wherein a cut-out, preferably a groove, which is surrounded at least partly by the second coil, is provided at the cover or at the door or flap of the unit. 
     
     
         11 . A refrigerator unit and/or a freezer unit in accordance with  claim 10 , wherein the unit has a movably arranged cover; and the groove of the cover extends in the direction in which the cover is movable. 
     
     
         12 . A refrigerator unit and/or a freezer unit in accordance with  claim 10 , wherein the unit has a movably arranged cover and that the groove of the cover extends in a direction which extends at an angle, preferably at a right angle, to the direction in which the cover is movable. 
     
     
         13 . A refrigerator unit and/or a freezer unit in accordance with  claim 4 , wherein a component is provided at the cover or at the door or flap or that a component is provided at the carcass of the unit which is made of metal or comprises metal and is arranged such that it is surrounded at least partly by the first and second coils with a closed cover or with a closed door or flap. 
     
     
         14 . A refrigerator unit and/or a freezer unit in accordance with  claim 13 , wherein the component is connected to the cover or to the door or flap and is surrounded by the second coil and is arranged such that it is introduced into the cut-out, which is surrounded by the first coil, at least regionally independently of the position of the cover or of the door or flap or in one specific position or in a plurality of positions of the cover or of the door or flap, preferably in their closed position. 
     
     
         15 . A refrigerator unit and/or a freezer unit in accordance with one of the  claims 13 , wherein the component is connected to the carcass and is surrounded by the first coil and is arranged such that it is introduced into the cut-out, which is surrounded by the second coil, on the reaching of the specific position, preferably on the closing of the cover, door or flap. 
     
     
         16 . A refrigerator unit and/or a freezer unit in accordance with  claim 1 , wherein the heating device is formed by a heating film located on the pane.
