When viewed vertically on a main extension plane of the insulation unit, the insulation unit extends in particular over a proportion of at least 20%, in particular at least 40%, advantageously at least 60%, particularly advantageously at least 70% and preferably at least 80% of an area, in particular a wall, the first structural unit, on which the insulation unit is arranged in particular. In particular, in an installation position when viewed vertically on a main extension plane of the insulation unit, an area extension of the insulation unit is greater than an area extension of the second structural unit.

A “main extension plane” of an object is to be understood to mean, in particular, a plane which is parallel to a largest side surface of a smallest imaginary cuboid, which just just completely surrounds the object, and in particular runs through the center of the cuboid. “At least for the most part” is to be understood in particular to mean a proportion, in particular a mass fraction and / or volume fraction, of at least 70%, in particular of at least 80%, advantageously of at least 90% and preferably of at least 95%.

 For example, the insulation unit could have at least one main function, which in particular could be thermal insulation between the first structural unit and the second structural unit. The insulation unit has in particular at least one main function, which lies in particular in electrical insulation between the first structural unit and the second structural unit. In particular, the insulation unit, in particular in addition to the main function in the form of electrical insulation between the first structural unit and the second structural unit, has at least one secondary function, which lies in particular in thermal insulation between the first structural unit and the second structural unit.

The phrase that the insulation unit is provided for insulation “between” at least one first structural unit and at least one second structural unit is to be understood in particular to mean that the insulation unit is used to isolate the first structural unit from the second structural unit and / or to provide insulation the second structural unit with respect to the first structural unit and / or with an isolation of the first structural unit from the second structural unit and also the second structural unit from the first structural unit. In at least one operating state, the insulation unit in particular reduces a transfer of energy, in particular electrical energy and / or thermal energy, between the first structural unit and the second structural unit, in particular in a measurable manner, in particular in comparison to an embodiment while avoiding and / or in the absence of an isolation unit. In at least one operating state, the insulation unit absorbs in particular the energy from the first structural unit and / or from the second structural unit and in particular absorbs this energy at least in large part and / or in particular prevents transmission of the energy between the first structural unit and the second structural unit. In particular, the insulation unit in at least one operating state reduces the likelihood of an in particular electrical short circuit between the first structural unit and the second structural unit, in particular in a measurable manner, in particular in a comparison to a configuration with avoidance and / or absence of an insulation unit. In particular, the insulation unit, in at least one operating state, reduces the probability of heat transfer between the first structural unit and the second structural unit, in particular in a measurable manner, in particular in a comparison to a configuration with the avoidance and / or absence of an insulation unit.

 In particular, an external shape and / or shape of the insulation unit can be changed and / or adapted to an outer shape and / or shape of the first structural unit by means of the auxiliary installation element. The insulation unit can be bent and / or bent, in particular by means of the auxiliary installation element, in particular in a simple manner. In particular, by means of the auxiliary installation element, at least two partial areas of the insulation unit, which, in at least one disassembled state, can be arranged in particular adjacent to one another, can be arranged one above the other and / or overlapping, in particular with respect to at least one direction, which is in particular perpendicular to a main extension plane of at least one of the Partial areas is aligned.

A “disassembled” state, in particular the insulation unit, is to be understood in particular to mean a state in which the insulation unit is arranged, in particular, at least for the most part within one level and / or in which the insulation unit is developed in particular in one plane. The disassembled state is located, in particular, in terms of time before the insulation unit is assembled and / or before the insulation unit is arranged on the first structural unit. In the demon- tated state, the insulation unit assumes a maximum area extension, in particular when viewed vertically on at least a partial area of the isolation unit in a plane which is spanned by the partial area. In particular, the insulation unit is free of kinks and / or undulations and / or bends in the disassembled state.

 The phrase that the expansion compensation element is intended to at least substantially “compensate” a thermal expansion of at least a partial area of the insulation unit is to be understood in particular to mean that the expansion compensation element transmits the thermal expansion of the partial area from the partial area to at least one operating state at least one, in particular surrounding the partial area and / or adjacent to the partial area, further partial area of the insulation unit at least substantially prevented and / or reduced, in particular in a comparison to a configuration with avoidance and / or in the absence of the expansion compensation element. In particular, the expansion compensation element in at least one operating state absorbs at least a large part of a thermal expansion of the partial area of the insulation unit. The expansion compensation element reduced in at least one operating state, in particular a thermal expansion of the partial area of the insulation unit, in particular in a comparison to a configuration with avoidance and / or in the absence of the expansion compensation element.

 The expansion compensation element is arranged in particular in a region of the insulation unit in which maximum thermal voltages occur in the insulation unit in a heating operating state. In particular, a direction of longitudinal extension of the expansion compensation element is oriented at least substantially perpendicular to a direction of the thermal stresses. The auxiliary installation element is particularly in an area of the insulation unit, in which in a Heizbetriebszu stood low thermal stresses in the insulation unit.

A “longitudinal direction of extension” of an object is to be understood in particular as a direction which is aligned parallel to a longest side of a smallest imaginary cuboid which just just completely surrounds the object. The expression “essentially vertical” is intended here in particular to define an orientation of a direction relative to a reference direction, the direction and the reference direction, viewed in particular in one plane, enclosing an angle of 90 °. and the angle has a maximum deviation of in particular a maximum of 8 °, advantageously a maximum of 5 ° and particularly advantageously a maximum of 2 °.

 The term “intended” is to be understood in particular to be specially designed and / or equipped. The fact that an object is provided for a specific function should in particular be understood to mean that the object fulfills and / or carries out this specific function in at least one application and / or operating state.

It is further proposed that a longitudinal direction of at least one section of the auxiliary laying element in at least one disassembled state is oriented at an angle to a longitudinal direction of at least a section of the expansion compensation element. In particular, the section of the laying aid element and the section of the expansion compensation element in at least one disassembled state are arranged at least for the most part in an in particular common plane, which is in particular spanned by the insulation unit. The auxiliary installation element could, for example, have exactly one section which, in particular, could at least largely and advantageously completely define a shape and / or shape of the auxiliary installation element. Alternatively, the auxiliary installation element could in particular have at least two, in particular at least three, advantageously at least four, particularly advantageously at least five, preferably at least seven and particularly preferably a plurality of sections, which in particular together have at least a large part and advantageously a shape and / or shape of the auxiliary installation element could fully define. The expansion compensation element could, for example, have exactly one section, which could in particular at least largely and advantageously completely define a shape and / or shape of the expansion compensation element. Alternatively, the expansion compensation element could in particular have at least two, in particular at least three, advantageously at least four, particularly advantageously at least five, preferably at least seven and particularly preferably a plurality of sections, which in particular together have at least a large part the shape and / or shape of the expansion compensation element and could advantageously completely defi nate. The phrase that a direction is oriented “at an angle” to a further direction is to be understood in particular to mean that the direction with the further direction, in particular in a plane within which the direction and the further direction are arranged and which in particular of the insulation unit stretches, includes a minimum angle of more than 0 ° and a maximum of 90 °. In particular, the longitudinal direction of extension of the section of the auxiliary laying element closes a minimum angle of at least 5 °, in particular of at least 10 °, advantageously of at least 15 °, particularly advantageously of at least 20 °, preferably of at least 30 ° and particularly preferably, in at least one disassembled state of at least 40 ° with the longitudinal direction of the section of the expansion compensation element. In particular, the longitudinal extension direction of the section of the auxiliary installation element in at least one disassembled state has a minimum angle of at most 90 °, in particular of at most 85 °, advantageously of at most 80 °, particularly advantageously of at most 70 °, preferably of at most 60 ° and particularly preferably of at most 50 ° with the longitudinal direction of the section of the expansion compensation element. As a result, the section of the installation aid element and the section of the expansion compensation element can in particular be arranged in a particularly flexible manner relative to one another, in particular in such a way as to ensure optimum functionality of the installation aid element and of the expansion compensation element. In particular, optimal laying of the insulation unit can be made possible and / or thermal expansion of the partial region of the insulation unit can be optimally compensated for.

In addition, it is proposed that the auxiliary installation element in at least one disassembled state have at least one incision in the insulation unit and in particular is formed by at least one incision in the insulation unit. For example, the auxiliary installation element could have at least two, in particular at least three, advantageously at least four, particularly advantageously at least five, preferably at least seven and particularly preferably a plurality of notches which could merge into one another in particular and which in particular could have different directions of elongation, in particular angular could be aligned relative to each other. The auxiliary installation element has in particular exactly one incision, which is in particular designed in a straight line. An “incision” is to be understood in particular to mean a slot and / or an elongate recess which, for example, could be produced by means of at least one cutting process and / or by means of at least one process different from a cutting process and / or introduced into the insulation unit. In particular, this enables inexpensive and / or simple manufacture to be achieved. In particular, on in a simple manner, an optimal and / or maximum effect can be achieved, which in particular enables high efficiency.

 It is further proposed that the auxiliary installation element in at least one disassembled state adjoins a lateral edge of the insulation unit and in particular based on the lateral edge of the insulation unit to which the auxiliary installation element adjoins in at least one disassembled state, in the direction of at least one further lateral edge of the Isolation unit and / or in the direction of an inner region of the isolation unit. A “lateral” border of the insulation unit in at least one disassembled state should in particular be understood to mean a border and / or an edge, which in the disassembled state is a surface extension of the insulation unit that the insulation unit in particular when viewed vertically on a main extension plane of the insulation unit in the main extension level, limited and / or defined and / or bordered. In particular, this enables an optimal adaptation of an external shape of the insulation unit to the first structural unit and / or an optimal laying of the insulation unit on the first structural unit. In particular, the auxiliary installation element can be produced in a simple and / or uncomplicated manner, since in particular simple accessibility can be ensured during manufacture of the auxiliary installation element.

 For example, in at least one disassembled state, the auxiliary installation element could be oriented at an angle to the lateral edge of the insulation unit and / or in particular include a minimum angle of at least substantially 90 ° with the lateral edge. In at least one disassembled state, the installation aid element preferably includes a minimum angle of at least substantially 45 ° with the lateral edge of the insulation unit. In this context, “at least essentially” should be understood in particular to mean that a deviation from a predefined value deviates in particular not more than 25%, preferably not more than 10% and particularly preferably not more than 5% of the predefined value. As a result, in particular an outer shape of the laying aid element can be adapted particularly optimally to the first structural unit

In addition, it is proposed that the expansion compensation element have at least one material weakening of the insulation unit in at least one disassembled state, and in particular by at least one material weakening of the insulation unit is formed. A “material weakening” of an object is to be understood in particular as a partial area of the object in which the object is relative to at least one further partial area of the object and / or relative to remaining partial areas of the object, which / which could / could be larger than that Subarea and which / which in particular could / could at least largely define and / or form the object has at least a reduced material thickness and / or thickness. A “thickness” of an object is to be understood in particular to mean the shortest extension of a smallest imaginary cuboid that just barely surrounds the object. The material weakening could, for example, be a recess and / or a hole and / or a slot and / or a reduced material thickness and / or a recess in the insulation unit. The material weakening is advantageously a cut in the insulation unit. As a result, in particular, thermal expansion of at least a portion of the insulation unit can be optimally compensated for in a simple manner, as a result of which, in particular, deformation of the insulation unit and / or movement of the second structural unit relative to the first structural unit can be avoided.

 The expansion compensation element could, for example, adjoin a lateral edge of the insulation unit in at least one disassembled state when viewed vertically on a main extension plane of the insulation unit. The expansion compensation element is preferably arranged in at least one disassembled state when viewed vertically on a main extension plane of the insulation unit completely within a surface extension of the insulation unit in the main extension plane. A high degree of stability can thereby be made possible.

For example, the household appliance device could have exactly one, in particular only, insulation unit, in particular the insulation unit. The household appliance device preferably has at least one further insulation unit, which has at least one further installation auxiliary element, which is provided in particular for adapting an outer shape of the further insulation unit to the first structural unit for the purpose of laying the further insulation unit, and at least one further expansion compensation element, which In particular, it is provided to at least substantially compensate for a thermal expansion of at least a portion of the further insulation unit, and which is reflected in at least one times different from the isolation unit. This allows, in particular, an arrangement of at least two insulation units one above the other and / or in an overlapping manner, in particular with respect to a direction oriented perpendicular to one of the insulation units, thereby in particular an optimized and / or maximum insulation between the first structural unit and the second Unit can be achieved.

The insulation unit and the further insulation unit could differ from one another in at least one disassembled state, for example by a number of auxiliary installation elements and / or by a number of expansion compensation elements. Alternatively or additionally, the insulation unit and the further insulation unit could differ in at least one disassembled state, for example, by arranging at least one auxiliary installation element and / or at least one expansion compensation element relative to a lateral edge of the insulation unit and / or relative to one another. For example, the insulation unit and the further insulation unit could alternatively or additionally differ in terms of a surface extension and / or by an external shape. In at least one disassembled state, the insulation unit and the further insulation unit preferably have at least essentially the same surface extension and advantageously at least essentially the same external shape. The phrase that the insulation unit and the further insulation unit in at least one disassembled state “at least essentially” have the same area extension should be understood in particular that in at least one disassembled state, a quotient of an area extension of the insulation unit and an area extension of the further insulation unit assumes a value of at least 0.9, in particular of at least 0.92, advantageously of at least 0.94, particularly advantageously of at least 0.96, preferably of at least 0.98 and particularly preferably of at least 0.99 and / or that in at least one disassembled state, a quotient of a surface extension of the insulation unit and a surface extension of the further insulation unit has a value of a maximum of 1.1, in particular a maximum of 1.08, advantageously a maximum of 1.06, particularly advantageously a maximum of 1.04 , preferably of at most 1, 02 and be particularly preferred of maximum 1, 01 assumes. As a result, the insulation unit and the further insulation unit can be superimposed and / or in particular in an optimal manner be arranged overlapping, which in particular an optimized and / or maximum insulation effect can be made possible.

 Furthermore, it is proposed that in at least one disassembled state, when viewed vertically on a main extension plane of the insulation unit and in the case of an overlapping arrangement of the insulation unit and the further insulation unit, the installation aid element and the further installation aid element are arranged without overlap. In particular, in at least one disassembled state when viewed vertically on a main extension plane of the insulation unit and in the case of the overlapping arrangement, there is at least one side edge of the insulation unit and at least one side edge of the further insulation unit, in particular side edges of the insulation unit and side edges of the others Isolation unit, one on top of the other and / or one above the other. As a result, in particular in a simple and / or uncomplicated manner, a direct and / or electrically conductive contact of the first structural unit and the second structural unit with one another can be avoided, as a result of which, in particular, high functionality and / or high functionality can be achieved.

 It is further proposed that the expansion compensation element and the further expansion compensation element are arranged without overlap in at least one disassembled state when viewed vertically on a main extension plane of the insulation unit and in the case of an overlapping arrangement of the insulation unit and the further insulation unit. As a result, in particular an, in particular electrically conductive, contact of the first structural unit and the second structural unit and / or the occurrence of electrical short circuits can be avoided, as a result of which a high level of operating comfort and / or a long-lasting design and / or high functionality can be achieved.

The isolation unit could, for example, be asymmetrical, such as with respect to a center and / or center of gravity of the isolation unit. In particular, the household appliance device, in particular in the case of an asymmetrical insulation unit, could have at least one second insulation unit, which could be identical to the insulation unit. In particular, the isolation unit and the further isolation unit could be arranged at least in a disassembled state and in the case of an overlapping arrangement of the isolation unit and the second isolation unit rotated relative to one another, for example by rotating the second insulation unit, in particular about an axis of rotation, which is oriented perpendicular to the second insulation unit and runs through a center and / or center of gravity of the second insulation unit, through an angle of at least substantially 90 ° and / or at least substantially 180 °. In at least one disassembled state and in the case of an overlapping arrangement of the insulation unit and the second insulation unit, in particular the installation aid element of the insulation unit and a second installation aid element of the second insulation unit could be arranged without overlap. In at least one disassembled state and in the case of an overlapping arrangement of the insulation unit and the second insulation unit, in particular the expansion compensation element of the insulation unit and a second expansion compensation element of the second insulation unit could be arranged without overlap. In this way, in particular a low level of storage and / or a small number of components could be made possible.

 The insulation unit and / or the further insulation unit is preferably of symmetrical design, as a result of which, in particular, simple assembly can be achieved.

For example, the insulation unit could be formed in one piece and the further insulation unit could have at least one further first insulation part element and at least one further second insulation part element, which in particular could be provided for modular assembly. Alternatively, for example, the further insulation unit could be formed in one piece and the insulation unit could have at least one first insulation part element and at least one second insulation part element, which in particular could be provided for modular assembly. The insulation unit is preferably formed in one piece and, in particular in addition to the first insulation unit, in particular the further insulation unit is formed in one piece. “One-piece” is to be understood in particular to be understood as being at least integrally bonded, for example by means of a welding process, an adhesive process, a gating process and / or another process which appears to be useful to the person skilled in the art, and / or advantageously to be formed in one piece, such as, for example, by a Manufacture from a casting and / or by manufacturing in a single or multi-component injection molding process and advantageously from a single blank. In particular, a stable construction and / or simple manufacture of the insulation unit and / or the further insulation unit can thereby be achieved. In particular, low inventory and / or low component diversity can be achieved. Furthermore, it is proposed that the insulation unit and in particular the further insulation unit have at least one first partial insulation element and at least one second partial insulation element, which are provided for modular assembly. In particular, the further insulation unit has at least one further first partial insulation element and at least one further second partial insulation element, which are provided in particular for a modular assembly. The phrase that a first object and a second object are provided for a “module-like” assembly is to be understood in particular to mean that the first object and the second object are provided for assembly in the modular principle and / or in the modular principle and in particular in such a manner are that the first object and the second object can be joined together in particular due to a suitable shape and / or due to a suitable functionality and / or can interact via corresponding interfaces. This allows a particularly flexible configuration, in particular.

For example, the first partial insulation element and the second partial insulation element could be at least substantially and in particular completely identical. The further first partial insulation element and the further second partial insulation element could for example be at least substantially and in particular completely identical. In particular, the first partial insulation element and the second partial insulation element could differ in at least one feature from the further first partial insulation element and the further second partial insulation element. Preferably, the first insulating sub-element and the second insulating sub-element differ from one another in at least one feature, in particular in size and / or shape. The further first partial insulation element and the further second partial insulation element differ from one another in particular in at least one feature, in particular in size and / or shape. The feature in which the insulating sub-elements differ from one another could be, for example, a size and / or a shape. Alternatively or additionally, the feature in which the insulation sub-elements differ from one another could be, for example, an arrangement of at least one auxiliary installation element of an insulation unit, in particular any one, relative to a lateral edge and / or relative to at least one expansion compensation element of the insulation unit. The feature in which, in particular, the insulating sub-elements differ from one another differ, could alternatively or additionally be, for example, arrangement of at least one expansion compensation element of any particular insulation unit relative to a lateral edge and / or relative to at least one laying aid element of the insulation unit. This allows in particular an extremely high flexibility and / or a, in particular direct electrical contact between the first structural unit and the second structural unit can be avoided, in particular in the case of an overlapping arrangement of the insulation unit and the further insulation unit.

 In addition, it is proposed that the isolation unit and / or the further isolation unit consist at least to a large extent of mica, in particular of artificial mica. As a result, the insulation unit and / or the further insulation unit can consist, in particular, at least in large part of a material with an optimized price-performance ratio, which in particular enables high economic efficiency.

 Isolation between the first structural unit and the second structural unit can in particular be perfected in a household appliance, in particular in a household cooking appliance, with at least one household appliance device according to the invention.

 A high degree of security and / or a high degree of functionality can in particular be achieved by a method for operating a household appliance device according to the invention, which has at least one insulation unit which is provided for insulation between at least a first structural unit and at least a second structural unit , wherein for the purpose of laying the insulation unit, an outer shape of the insulation unit is adapted to the first structural unit, and wherein a thermal expansion of at least a portion of the insulation unit is at least substantially compensated for.

 The household appliance device is not intended to be limited to the application and embodiment described above. In particular, the household appliance device can have a number that differs from a number of individual elements, components and units specified here to fulfill a function described here.
