     By a “home appliance door” is in particular to be understood a door of a home appliance device and/or of a home appliance. By a “home appliance device” is in particular to be understood at least a portion, preferably a sub-assembly group, of a home appliance. The home appliance is in particular provided for storing and preferably tempering victuals such as beverages, meat, fish, vegetables, fruits, milk and/or dairy products in at least one operating state, advantageously for the purpose of enhancing a keepability of the stored victuals. For example, the home appliance is embodied as a home chiller appliance, which is in at least one operating state configured for cooling victuals. The home chiller appliance could in particular be embodied as a climate cabinet, an ice-box, a refrigerator, a freezer, a refrigerator-freezer combination and/or a wine cooler. However, the home appliance could also be embodied as a home appliance for warming and in particular for cooking victuals, e.g. an oven and/or a steamer and/or a microwave. Alternatively, the home appliance could also be embodied as a home appliance for cleaning, e.g. a washing machine and/or a dryer and/or a dishwasher. The home appliance may in particular comprise at least two, in particular at least three and preferably at least four home appliance devices. 
     A “door unit” is in particular to be understood as a unit which is, in at least one assembled state, connected to an appliance body in a movable and in particular swiveling fashion and which at least partly defines, in at least one operating state, at least one storage space. In at least one operating state the door unit in particular defines the storage space together with the appliance body. The door unit in particular comprises at least one seal, which is in particular provided for sealing at least one gap between the inner wall and the appliance body in at least one operating state. The door unit itself, in particular without the covering element, is in particular sufficient for closing at least one storage space and/or for sealing at least one gap between the inner wall and the appliance body. The door unit can, for example, at least partly comprise at least one stamped part and/or at least one stamped portion. Alternatively and/or additionally, the door unit can for example comprise at least partly one thermoforming part and/or at least one thermoforming portion. 
     The appliance body is in particular part of a home appliance device, which in particular also comprises the home appliance door. An “appliance body” is in particular to be understood as a unit at least partly defining at least one storage space and in particular defining the storage space at least substantially together with at least one home appliance door. In particular, the home appliance device comprises, in at least one operating state, the home appliance door. The appliance body and the home appliance in particular define the storage space in at least one operating state at least substantially and preferably by considering tolerances completely. The appliance body in particular comprises at least two, in particular at least four and preferably at least five walls. The walls in particular delimit the storage space. The walls may in particular be embodied as a lateral wall and/or as a rear wall and/or as a bottom wall and/or as a top wall. The appliance body in particular has two lateral walls, preferably opposite each other, one rear wall, one bottom wall and one top wall, which is preferably situated opposite the bottom wall. 
     In at least one operating state, the inner wall of the door unit is in particular located facing the storage space and/or the appliance body, in particular the rear wall of the appliance body. In at least one operating state, the outer wall is in particular located facing a user. In at least one assembled state, the inner wall and the outer wall are connected and/or fixed to one another, thereby in particular defining at least one interior space. The interior space is, in at least one assembled state, in particular at least partly and preferably at least mostly filled with insulation material. The inner wall and/or the outer wall can for example be in particular at least partly thermoforming parts/a thermoforming part. 
     The term “at least mostly” with reference to an object is in particular to mean by more than 50% or more than 65% or by more than 80% or by more than 95% of that object, in particular of a surface area and/or of a volume and/or of a mass of the object. An “operating state” is in particular to be understood as a state in which the storage space is closed and an access to the storage space is prevented, in particular by the door unit. In the operating state, the door unit and the appliance body are in particular located with respect to one another in a manner with a maximum contact area. 
     A “covering element” is in particular to be understood as an element having the main function of covering at least one feature of the inner wall. For example, the covering element can in particular have at least one further function which is of less priority than the main function. The main function of the covering element is in particular the reason for using the covering element. An element covering at least one feature of the inner wall and having a main function that differs from covering at least one feature of the inner wall is in particular not to be understood as a covering element. The covering element can for example be in particular at least partly a stamped part. In particular, the covering element differs from at least one door bin and/or shelf. 
     The term that the covering element “at least partly” covers at least one feature of the inner wall is in particular to mean that the covering element covers more than 50% or by more than 65% or by more than 75% or by more than 85% of the feature of the inner wall. 
     In this context, “configured” is in particular to mean specifically programmed, designed and/or equipped. By an object being configured for a certain function is in particular to be understood that the object implements and/or fulfills said certain function in at least one application state and/or operating state. 
     By means of the invention, in particular a high level of convenience for a user can be provided. Features of the inner wall and/or located on the inner wall can in particular be covered in an easy and/or cost-saving manner. The home appliance door and in particular the covering element can in particular be used for several and preferably for any brands. It is in particular possible to change the design of the covering element in an easy manner, in particular just using different types of material and/or coloring, thereby in particular creating different designs for different brands and/or types of home appliance doors. 
     Further, it is proposed that the covering element is embodied as a covering plate. The covering element has in particular at least one longitudinal extension and at least one transverse extension, which are at least 5 times or at least 10 times or at least 20 times or at least 50 times larger than at least one thickness of the covering element. In this context, a “longitudinal extension” of an object is in particular to be understood as an extension of the longest side of an imaginary smallest rectangular cuboid just still entirely encompassing the object. In this context, a “transverse extension” of an object is in particular to be understood as an extension of the second-longest side of an imaginary smallest rectangular cuboid just still entirely encompassing the object. In this context, a “thickness” of an object is in particular to be understood as an extension of the shortest side of an imaginary smallest rectangular cuboid just still entirely encompassing the object. In particular, the longitudinal extension and the transverse extension and the thickness are perpendicular to one another, respectively. On account of this, the covering element can in particular be produced and/or manufactured in an easy and/or fast manner. 
     Further, it is proposed that the covering element is fixed to the inner wall. As a result of this, a high stability can in particular be provided. 
     The covering element can in particular be fixed to the inner wall by means of a friction-fit connection and/or by means of a form-fit connection. Preferably the covering element is fixed to the inner wall by means of an adhesive bond. For example, the covering element can be fixed to the inner wall by means of a tape and/or double-sided tape. In this way, in particular a stable and/or cost-saving implementation can be provided. A usage of screws can in particular be avoided, thus in particular reducing the number of parts used. 
     The feature of the inner wall and/or located on the inner wall which may be covered by the cover element can in particular comprise quality problems, such as in particular a usage of too many parts and/or at least one gap located on the inner wall and/or at least one scratch located on the inner wall. Additionally and/or alternatively, the feature can in particular comprise mechanical parts, such as in particular at least one rail and/or at least one screw and/or at least one air duct and/or at least one elbow and/or mechanical details. Preferably, the feature comprises at least one re-enforcing element and/or at least one air duct and/or at least one rail of the inner wall. The re-enforcing element strengthens and/or reinforces in particular the inner wall and/or the door unit. In at least one assembled state, the rail is in particular provided for mounting of at least one door bin in particular of the home appliance door. As a result of this, a high-grade convenience for a user can in particular be provided. 
     In an exemplary implementation of the invention it is proposed that the home appliance door further comprises at least one rail. For example, the rail and the covering element can in particular be connected to each other, wherein the rail can in particular be connected to a surface of the covering element. Alternatively, the rail and the covering element can in particular be made of one piece. The rail can in particular be embodied as a projection of the covering element. Preferably the rail and the door unit are in particular connected to each other, wherein the rail is in particular connected to the inner wall of the door unit. For example, the covering element can comprise at least one recess through which the rail projects. The rail and the recess of the covering element can in particular be adapted to one another, in particular in size and/or form and/or location. In particular, the rail and the recess can be located correspondingly to one another. It is also proposed that the rail may be located at least completely behind the covering element. The covering element defines at least one plane behind which the rail is located. For example, the rail can be covered by the covering element. The covering element may comprise at least one recess through which the rail can be seen in a front view. This allows, in particular, providing a compact implementation. 
     Further, it is proposed that the home appliance door may further comprise at least one door bin and that the covering element comprises at least one recess through which the door bin may be fixed to the rail. In particular, the door bin may be provided for storing victuals to be cooled and/or tempered, for example bottles and/or milk and/or juice and/or butter and/or food and/or groceries. The door bin can for example be fixed to the rail in a permanent fashion. Alternatively, the door bin may be fixed to the rail in a releasable fashion. As a result of this, a high convenience for a user can in particular be provided. 
     Additionally, it is proposed that the inner wall comprises at least one groove, in which the rail is located. In particular, the inner wall comprises at least one delimiting element which in particular delimits and/or defines the groove. In this context, a “delimiting element” is in particular to be understood as a portion of the inner wall, defining and/or bordering the groove. The groove can in particular be a ridge of the inner wall. In particular, the groove is opened towards the covering element. This allows, in particular, providing a compact implementation. 
     Additionally, it is proposed that the home appliance door further comprises at least one support element located between the inner wall and the outer wall and attached to a rear side of at least one delimiting element of the inner wall, which delimits the groove. In this context, a “support element” is in particular to be understood as an element, being separate from the inner wall and supporting and/or reinforcing the groove and/or the delimiting element and/or the inner wall. In at least one mounted state, the support element is in particular located within the interior space in particular defined by the outer wall and the inner wall. In particular, the rail is fixed to the support element in at least one mounted state, in particular by means of at least one fixing element. The door unit in particular comprises at least one fixing element, which in particular fixes the rail to the support element in at least one mounted state. For example, the fixing element can be a latching element. The fixing element may also be a screw. The support element in particular is embodied at least mostly of metal. The support element may have at least one at least essentially U-shaped region which is in particular attached to the rear side of the delimiting element. The support element may have at least one further region contacting a rear side of the inner wall beside the groove. Alternatively and/or additionally, the support element may have at least one further region extending into the interior space without contacting the inner wall and the outer wall. As a result of this, an improved fixation of the support element by at least one solidified insulation material, located within the interior space, can in particular be provided. For example, the home appliance door can comprise several support elements, being arranged along a height direction of the door unit. Alternatively, the home appliance door can comprise exactly one support element for each delimiting element of the inner wall, e.g. two support elements in total. The support element can for example be an extruded part. In this way, the rail is in particular fixed to the inner wall and/or to the solidified insulation material and/or to the support element. The rail may not be fixed to the covering element. As a result of this, no forces acting on the rail are transmitted onto the covering element. 
     In addition, it is proposed that the covering element comprises at least one air recess, which is located correspondingly to at least one air duct of the inner wall. The home appliance door can in particular comprise at least one ventilation which in particular leads to the air duct of the inner wall. On account of this, a storage time of victuals to be cooled and/or tempered which are stored in the storage space can in particular be prolonged. 
     For example, the covering element can in particular be mounted to an in particular flat surface of the inner wall. For example, the inner wall may comprise at least one flange on which the covering element is mounted. As a result of this, a high stability can in particular be provided. 
     Furthermore, it is proposed that the covering element and at least one portion of the inner wall may be arranged flush with each other. The term that the covering element and at least one portion of the inner wall are arranged “flush” with each other is in particular to mean that a small offset and/or tolerances are admissible and/or allowed. On account of this, a compact implementation can in particular be provided. In particular, requirements of a flat door concept can be fulfilled. The at least one portion of the inner wall may surround one, two or all edges of the covering element. 
     It is also proposed that the covering element is at least mostly made of metal, e.g. sheet metal. For example, the covering element can in particular be at least mostly made of aluminum and/or stainless steel and/or galvanized steel. The covering element can in particular be painted and/or varnished. As a result of this, a high stability can in particular be provided. 
     A convenience for a user can in particular be enhanced by a home appliance device, in particular a home chiller appliance device, comprising at least one home appliance door according to the invention. 
     A convenience for a user can in particular be further improved by a home appliance, in particular a home chiller appliance, comprising at least one home appliance device, in particular at least one home chiller appliance device, according to the invention. 
     A comfortable and/or convenient solution can in particular be provided by a method for assembly of a home appliance door, in particular a home chiller appliance door, according to the invention; the home appliance door comprising: at least one door unit having an outer wall and an inner wall; at least one feature of the inner wall being at least partly covered. 
     Herein the home appliance door and/or the home appliance device is not to be limited to the application and implementation described above. In particular, for the purpose of fulfilling a functionality herein described, the home appliance door and/or the home appliance device may comprise a number of respective elements, structural components and units that differs from the number mentioned herein. Furthermore, regarding the value ranges mentioned in this disclosure, values within the limits mentioned are to be understood to be also disclosed and to be used as applicable.
