CLASSIFICATION ## Abstract A method for manufacturing a water-bearing domestic appliance having a washing container to accommodate items to be washed, wherein the washing container is at least partially formed by at least two different metallic materials. ## Claims ### Claim 1 A method for manufacturing a water-bearing domestic appliance having a washing container to accommodate items to be washed, the method comprising forming the washing container at least partially by at least two different metallic materials by joining the two different metallic materials to one another along a seam. ### Claim 2 (depends on 1) The method of claim 1, wherein the water-bearing domestic appliance is one of a dishwasher and a washing machine. ### Claim 3 (depends on 1) The method of claim 1, wherein at least one of the two different metallic materials is stainless steel. ### Claim 4 (depends on 1) The method of claim 1, wherein the at least two different metallic materials have a respectively different content of austenite formers. ### Claim 5 (depends on 4) The method of claim 4, wherein the austenite formers are at least one of nickel, cobalt and manganese. ### Claim 6 (depends on 1) The method of claim 1, wherein at least one of the at least two different metallic materials is austenitic metal. ### Claim 7 (depends on 1) The method of claim 1, wherein at least one of the at least two different metallic materials is ferritic metal. ### Claim 8 (depends on 1) The method of claim 1, wherein a plastic sealer is applied to at least a predetermined connection area of the at least two different metallic materials. ### Claim 9 (depends on 1) The method of claim 1, wherein the washing container is formed by at least two main components. ### Claim 10 (depends on 9) The method of claim 9, wherein at least one of the at least two main components is manufactured from the at least two different metallic materials. ### Claim 11 (depends on 9) The method of claim 9, wherein at least one of the at least two main components forms at least one of a base, a container rear panel, and a roof of the washing container. ### Claim 12 (depends on 1) The method of claim 1, wherein an electrically insulating coating is applied at least in the predetermined connection area of the at least two different metallic materials. ### Claim 13 (depends on 1) The method of claim 1, wherein a passivation is applied at least in a predetermined connection area of the at least two different metallic materials. ### Claim 14 (depends on 13) The method of claim 13, wherein the passivation contains chrome. ### Claim 15 (depends on 1) The method of claim 1, further comprising arranging a sacrificial anode. ### Claim 16 (depends on 1) The method of claim 1, further comprising arranging a parasitic anode. ### Claim 17 (depends on 1) The method of claim 1, wherein at least one deformation takes place after connecting the at least two different metallic materials by a weld connection at least in a predetermined area of an austenitic metal. ### Claim 18 A water-bearing domestic appliance, comprising: a washing container to accommodate items to be washed, the washing container formed at least partially by at least two different metallic materials, wherein the two different metallic materials are fixedly joined to one another along a seam. ### Claim 19 (depends on 18) The water-bearing domestic appliance of claim 18, wherein the water-bearing domestic appliance is one of a dishwasher and a washing machine. ### Claim 20 (depends on 18) The water-bearing domestic appliance of claim 18, wherein at least one of the two different metallic materials is stainless steel. ### Claim 21 (depends on 18) The water-bearing domestic appliance of claim 18, wherein the at least two different metallic materials have a respectively different content of austenite formers. ### Claim 22 (depends on 18) The water-bearing domestic appliance of claim 18, wherein the austenite formers are at least one of nickel, cobalt and manganese. ### Claim 23 (depends on 18) The water-bearing domestic appliance of claim 18, wherein at least one of the at least two different metallic materials is austenitic metal. ### Claim 24 (depends on 18) The water-bearing domestic appliance of claim 18, wherein at least one of the at least two different metallic materials is ferritic metal. ### Claim 25 (depends on 18) The water-bearing domestic appliance of claim 18, wherein the washing container is formed by at least two main components. ### Claim 26 (depends on 18) The water-bearing domestic appliance of claim 18, further comprising a plastic sealer provided in at least a predetermined connection area of the at least two different metallic materials. ### Claim 27 (depends on 18) The water-bearing domestic appliance of claim 18, further comprising an electrically insulating coating provided in at least a predetermined connection area of the at least two different metallic materials. ### Claim 28 (depends on 18) The water-bearing domestic appliance of claim 18, further comprising a passivation provided in at least a predetermined connection area of the at least two different metallic materials. ### Claim 29 (depends on 28) The water-bearing domestic appliance of claim 28, wherein the passivation contains chrome. ### Claim 30 (depends on 18) The water-bearing domestic appliance of claim 18, further comprising a sacrificial anode. ### Claim 31 (depends on 18) The water-bearing domestic appliance of claim 18, further comprising a parasitic anode. ### Claim 32 (depends on 18) The water-bearing domestic appliance of claim 18, wherein the at least two different metallic materials form the base and two side panels of the washing container. ### Claim 33 (depends on 18) The water-bearing domestic appliance of claim 18, wherein the two different metallic materials are welded to one another. ### Claim 34 (depends on 18) The water-bearing domestic appliance of claim 18, wherein the washing container is substantially square. ### Claim 35 (depends on 34) The water-bearing domestic appliance of claim 34, wherein: the substantially square shape is formed by expanding a cylinder, the two different metallic materials are austenitic steel and ferritic steel, and the ferritic steel is disposed in areas that do not undergo significant metal deformation. ### Claim 36 A water-bearing domestic appliance, comprising: a washing container to accommodate items to be washed, the washing container formed at least partially by at least two different metallic materials, wherein the washing container is formed by at least two main components, and at least one of the at least two main components is manufactured from the at least two different metallic materials. ### Claim 37 (depends on 25) The water-bearing domestic appliance of claim 25, wherein at least one of the at least two main components forms at least one of a base, a container rear wall, and a roof of the washing container.
