Description

The invention relates to a household appliance device according to claim 1.

A domestic appliance device designed as an oven device with an insulation unit is already known from the prior art. The insulation unit is provided for electrical insulation between a first structural unit, which is designed as a muffle of an oven, and a second structural unit, which is designed as an induction heating line of the oven. In an assembled state, the insulation unit is arranged for the most part between the first structural unit and the second structural unit. In an assembled state, the insulation unit is arranged flat on a wall of the first structural unit. In the event of thermal heating of the insulation unit, for example due to a cooking process taking place in the muffle, there is a risk of deformation of the insulation unit, which could disrupt an optimal arrangement of the induction heating line arranged above the insulation unit relative to the muffle. The corresponding prior art can be found in the documents DE 198 22 034 A1 and EN 21 02 015 A1 refer to.

The object of the invention is in particular to provide a generic device with an advantageous construction. The object is achieved according to the invention by the features of claim 1, while advantageous embodiments and further developments of the invention can be found in the subclaims.

By such a design, an advantageous construction can be achieved.

It can, in particular by means of the expansion compensation element, in particular a Deformation of the insulation unit can be specifically prevented, whereby even at high temperatures an optimal arrangement of the second structural unit relative to the first structural unit and/or optimal heating of food arranged within the first structural unit can be ensured. The installation aid element allows the insulation unit to be arranged in particular flexibly and/or in any partial area on the first structural unit, in particular independently of the shape of the structural unit in the partial area. In particular, optimal, in particular electrical and/or thermal insulation between the first structural unit and the second structural unit can be made possible, whereby in particular a long-lasting design can be achieved.

A "household appliance device", in particular a "cooking appliance device", advantageously an "oven device" and particularly advantageously an "induction oven device" is to be understood as at least one part, in particular a subassembly, of a household appliance, in particular a cooking appliance, advantageously an oven and particularly advantageously an induction oven. For example, a household appliance having the household appliance device could be a freezer and advantageously a refrigerator and/or freezer. A household appliance having the household appliance device could alternatively or additionally be in particular a cleaning appliance, such as a dishwasher and/or a washing machine and/or a dryer. A household appliance having the household appliance device is advantageously a cooking appliance. A household appliance designed as a cooking appliance could, for example, be a hob, preferably an induction hob, and/or a microwave and/or a grill and/or a steamer. A household appliance designed as a cooking appliance is advantageously an oven and preferably an induction oven.

For example, the second structural unit could be larger than the first structural unit. The first structural unit is advantageously larger than the second structural unit. The phrase that an object is "larger" than another object is to be understood in particular to mean that the object has a mass and/or a volume which is at least 110%, in particular at least 120%, advantageously at least 150%, particularly advantageously at least 175%, preferably at least 200% and particularly preferably at least 250% of a mass and/or a volume of the other object.

For example, the first structural unit could be arranged in an installation position above the second structural unit. In an installation position, the second structural unit is arranged in particular above the first structural unit.

The household appliance device has in particular the first structural unit. The first structural unit could be, for example, a support plate and/or a hob plate, which could be provided in particular for setting up cooking utensils. The first structural unit is advantageously a muffle, which in particular at least partially defines and/or delimits at least one cooking chamber, which is provided in particular for introducing food to be cooked, in particular for the purpose of heating and/or cooking. The phrase that the muffle "at least partially" defines and/or delimits at least one cooking chamber is to be understood in particular to mean that the muffle defines and/or delimits the cooking chamber alone and/or together with at least one other unit, for example with at least one door.

The household appliance device has in particular the second structural unit. The second structural unit could, for example, be an electronic unit and/or a control unit and/or a user interface. The second structural unit is advantageously at least one heating unit. In this context, a "heating unit" is to be understood in particular as a unit which is intended to supply energy to at least one object to be heated in at least one operating state for the purpose of heating the object to be heated. For example, the heating unit could be designed as a resistance heating unit and in particular be intended to convert energy into heat and supply this to the object to be heated for the purpose of heating the object to be heated. Alternatively or additionally, the heating unit could be designed as an induction heating unit and in particular be intended to supply energy in the form of an alternating electromagnetic field to the object to be heated, wherein the energy supplied to the object to be heated could be converted into heat in particular in the object to be heated. The object to be heated could, for example, be a cooking vessel and/or at least one wall, in particular at least one muffle wall.

In particular, the insulation unit is arranged at least to a large extent between the first structural unit and the second structural unit in at least one assembled state. When viewed perpendicularly on a main extension plane of the insulation unit, the insulation unit extends in particular over a portion of at least 20%, in particular of at least 40%, advantageously of at least 60%, particularly advantageously of at least 70% and preferably of at least 80% of a surface, in particular of a wall, of the first structural unit on which the insulation unit is in particular arranged. In particular, in an installation position when viewed perpendicularly on a main extension plane of the insulation unit, a surface extension of the insulation unit is larger than a surface extension of the second structural unit.

A "main extension plane" of an object is to be understood in particular as a plane which is parallel to a largest side surface of a smallest imaginary geometric cuboid, which just completely encloses the object, and in particular runs through the center of the cuboid. "At least to a large extent" is to be understood in particular as a proportion, in particular a mass proportion and/or volume proportion, 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 could in particular be thermal insulation between the first structural unit and the second structural unit. The insulation unit in particular has at least one main function, which in particular is 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 in particular is 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 provided for insulation of the first structural unit from the second structural unit and/or for insulation of the second structural unit from the first structural unit and/or for insulation of both the first structural unit from the second structural unit and the second structural unit from the first structural unit.

In at least one operating state, the insulation unit particularly measurably reduces a transfer of energy, particularly electrical energy and/or thermal energy, between the first structural unit and the second structural unit, in particular in a comparison to an embodiment in which an insulation unit is avoided and/or absent. In at least one operating state, the insulation unit particularly absorbs the energy from the first structural unit and/or from the second structural unit and absorbs this energy, in particular at least to a large extent and/or in particular prevents a transfer of energy between the first structural unit and the second structural unit. In at least one operating state, the insulation unit particularly measurably reduces a probability of an electrical short circuit, in particular, between the first structural unit and the second structural unit, in particular in a comparison to an embodiment in which an insulation unit is avoided and/or absent. In at least one operating state, the insulation unit particularly measurably reduces a probability of heat transfer between the first structural unit and the second structural unit, in particular in a comparison to an embodiment in which an insulation unit is avoided and/or absent. In particular, the installation aid element can be used to change an external shape and/or form of the insulation unit and/or to adapt it to an external shape and/or form of the first structural unit. The insulation unit can be bent and/or folded using the installation aid element, in particular in a simple manner. In particular, the installation aid element can be used to arrange at least two sub-regions of the insulation unit, which in at least one dismantled state can be arranged adjacent to one another, one above the other and/or overlapping one another, in particular in at least one direction, which is aligned perpendicular to a main extension plane of at least one of the sub-regions.

A "dismantled" state, in particular of the insulation unit, is to be understood in particular as a state in which the insulation unit is arranged in particular at least to a large extent within a plane and/or in which the insulation unit is in particular unrolled in a plane. The dismantled state is in particular temporally located before the insulation unit is assembled and/or before the insulation unit is arranged on the first structural unit. In the dismantled In the disassembled state, the insulation unit assumes a maximum surface area, particularly when viewed vertically on at least a partial area of the insulation unit in a plane spanned by the partial area. In particular, the insulation unit is free of kinks and/or corrugations and/or bends in the disassembled state.

The phrase that the expansion compensation element is provided to at least substantially "compensate" a thermal expansion of at least one partial area of the insulation unit is to be understood according to the invention as meaning that the expansion compensation element in at least one operating state at least substantially prevents and/or reduces a transfer of the thermal expansion of the partial area from the partial area to at least one further partial area of the insulation unit, in particular surrounding the partial area and/or adjacent to the partial area, in particular in comparison to a design in which the expansion compensation element is avoided and/or absent. In particular, the expansion compensation element absorbs a thermal expansion of the partial area of the insulation unit at least to a large extent in at least one operating state. In particular, the expansion compensation element reduces a thermal expansion of the partial area of the insulation unit in at least one operating state, in particular in comparison to a design in which the expansion compensation element is avoided and/or absent.

The expansion compensation element is arranged in particular in a region of the insulation unit in which maximum thermal stresses occur in the insulation unit in a heating operating state. In particular, a longitudinal extension direction of the expansion compensation element is aligned at least substantially perpendicular to a direction of the thermal stresses. The installation aid element is arranged in particular in a region of the insulation unit in which low thermal stresses occur in the insulation unit in a heating operating state.

A "longitudinal direction" of an object is to be understood in particular as a direction which is aligned parallel to a longest side of a smallest imaginary geometric cuboid which just completely encloses the object. The expression "essentially perpendicular" is to be understood here in particular as defining an alignment of a direction relative to a reference direction, whereby the direction and the reference direction, in particular viewed in a plane, enclose 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" should be understood in particular to mean specially designed and/or equipped. The fact that an object is intended for a specific function should be understood in particular 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 extension direction of at least one section of the installation aid element in at least one dismantled state is aligned at an angle to a longitudinal extension direction of at least one section of the expansion compensation element. In particular, the section of the installation aid element and the section of the expansion compensation element in at least one dismantled state are arranged at least to a large extent in a plane, in particular a common plane, which is spanned in particular by the insulation unit. The installation aid element could, for example, have exactly one section, which in particular could define a shape and/or shape of the installation aid element at least to a large extent and advantageously completely. Alternatively, the installation aid 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 several sections, which in particular could together define a shape and/or shape of the installation aid element at least to a large extent and advantageously completely. The expansion compensation element could, for example, have exactly one section, which in particular could define a shape and/or form of the expansion compensation element at least to a large extent and advantageously completely. 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 several sections, which in particular together could define a shape and/or form of the expansion compensation element at least to a large extent and advantageously completely. The phrase that a direction is aligned "at an angle" to another direction is to be understood in particular to mean that the direction is aligned with the other direction, in particular in a plane within which the direction and the other direction are arranged and which is spanned in particular by the insulation unit. encloses a minimum angle of more than 0° and a maximum of 90°.

In particular, the longitudinal extension direction of the section of the installation aid element in at least one dismantled state encloses 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 of at least 40° with the longitudinal extension direction of the section of the expansion compensation element. In particular, the longitudinal extension direction of the section of the installation aid element in at least one dismantled state encloses a minimum angle of a maximum of 90°, in particular of a maximum of 85°, advantageously of a maximum of 80°, particularly advantageously of a maximum of 70°, preferably of a maximum of 60° and particularly preferably of a maximum of 50° with the longitudinal extension 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 be arranged particularly flexibly relative to one another, in particular in a way to ensure optimal functionality of the installation aid element and the expansion compensation element. In particular, optimal installation of the insulation unit can be enabled and/or thermal expansion of the partial area of the insulation unit can be optimally compensated.

According to the invention, the installation aid element has at least one incision in the insulation unit in at least one disassembled state. For example, the installation aid 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 several incisions, which could in particular merge into one another and which in particular could have different longitudinal extension directions from one another, which could in particular be aligned at an angle relative to one another. The installation aid element in particular has exactly one incision, which is in particular straight-line. According to the invention, an "incision" is a slot and/or an elongated recess, which could be produced and/or introduced into the insulation unit, for example, by means of at least one cutting process and/or by means of at least one process other than a cutting process. This makes it possible to achieve particularly cost-effective and/or simple production. In particular, An optimal and/or maximum effect can be achieved in a simple manner, which in particular enables high efficiency.

It is further proposed that the installation aid element in at least one dismantled state adjoins a lateral edge of the insulation unit and in particular, starting from the lateral edge of the insulation unit to which the installation aid element adjoins in at least one dismantled state, points in the direction of at least one further lateral edge of the insulation unit and/or in the direction of an inner region of the insulation unit. A "lateral" edge of the insulation unit in at least one dismantled state is to be understood in particular as an edge and/or an edge which, in the dismantled state, limits and/or defines and/or borders a surface extension of the insulation unit which the insulation unit spans in the main extension plane, in particular when viewed perpendicularly to a main extension plane of the insulation unit. This makes it possible in particular to optimally adapt an external shape of the insulation unit to the first structural unit and/or to optimally install the insulation unit on the first structural unit. In particular, the laying aid element can be manufactured in a simple and/or uncomplicated manner, since in particular easy accessibility can be ensured during manufacture of the laying aid element.

For example, the installation aid element could be aligned at an angle to the side edge of the insulation unit in at least one dismantled state and/or in particular enclose a minimum angle of at least substantially 90° with the side edge. Preferably, the installation aid element encloses a minimum angle of at least substantially 45° with the side edge of the insulation unit in at least one dismantled state. In this context, "at least substantially" is to be understood in particular as meaning that a deviation from a predetermined value deviates in particular by a maximum of 25%, preferably a maximum of 10% and particularly preferably a maximum of 5% of the predetermined value. In this way, an external shape of the installation aid element can be adapted in particular particularly optimally to the first structural unit.

In addition, it is proposed that the expansion compensation element has at least one material weakening of the insulation unit in at least one dismantled 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 has at least a reduced material strength and/or thickness relative to at least one further partial area of the object and/or relative to remaining partial areas of the object, which could in particular be larger than the partial area and which in particular could define and/or form the object at least to a large extent. A "thickness" of an object is to be understood in particular as a shortest extension of a smallest imaginary geometric cuboid which just 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 cutout in the insulation unit. The material weakening is advantageously an incision in the insulation unit. As a result, in particular a thermal expansion of at least a partial region of the insulation unit can be optimally compensated in a simple manner, whereby in particular a deformation of the insulation unit and/or a movement of the second structural unit relative to the first structural unit can be avoided.

The expansion compensation element could, for example, in at least one dismantled state when viewed perpendicularly on a main extension plane of the insulation unit, adjoin a lateral edge of the insulation unit. Preferably, in at least one dismantled state when viewed perpendicularly on a main extension plane of the insulation unit, the expansion compensation element is arranged completely within a surface extension of the insulation unit in the main extension plane. This makes it possible to achieve a high level of stability in particular.

For example, the household appliance device could have exactly one, in particular a single insulation unit, in particular the insulation unit. Preferably, the household appliance device has at least one further insulation unit, which has at least one further installation aid element, which is provided in particular for adapting an external shape of the further insulation unit to the first structural unit for the purpose of installing the further insulation unit, and at least one further expansion compensation element, which is provided in particular for at least substantially compensating for a thermal expansion of at least a partial area of the further insulation unit, and which is characterized in at least one feature from the insulation unit. This makes it possible in particular to arrange 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, whereby in particular an optimized and/or maximum insulation between the first structural unit and the second structural 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 installation aid elements and/or by a number of expansion compensation elements. Alternatively or additionally, the insulation unit and the further insulation unit could differ from one another in at least one disassembled state, for example by an arrangement of at least one installation aid 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 by a surface extension and/or by an external shape. Preferably, the insulation unit and the further insulation unit in at least one disassembled state have at least substantially the same surface extension and advantageously at least substantially the same external shape. The phrase that the insulation unit and the further insulation unit have "at least substantially" the same surface area in at least one dismantled state is to be understood in particular to mean that in at least one dismantled state a quotient of a surface area of the insulation unit and a surface area 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 dismantled state a quotient of a surface area of the insulation unit and a surface area of the further insulation unit assumes a value of at most 1.1, in particular of at most 1.08, advantageously of at most 1.06, particularly advantageously of at most 1.04, preferably of at most 1.02 and particularly preferably of at most 1.01. This allows the insulation unit and the further insulation unit to be optimally positioned one above the other and/or can be arranged overlapping, which in particular enables an optimized and/or maximum insulation effect.

It is further proposed that in at least one disassembled state, when viewed perpendicularly to 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 overlapping. In particular, in at least one disassembled state, when viewed perpendicularly to a main extension plane of the insulation unit and in the case of the overlapping arrangement, at least one lateral edge of the insulation unit and at least one lateral edge of the further insulation unit, in particular lateral edges of the insulation unit and lateral edges of the further insulation unit, lie on and/or above one another. As a result, direct and/or electrically conductive contact between the first structural unit and the second structural unit can be avoided in a simple and/or uncomplicated manner, whereby in particular a high level of functionality and/or a high level of functionality can be achieved.

It is further proposed that in at least one disassembled state, when viewed perpendicularly to 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 expansion compensation element and the further expansion compensation element are arranged without overlapping. This makes it possible to avoid in particular a contact, in particular an electrically conductive contact, between the first structural unit and the second structural unit and/or the formation of electrical short circuits, whereby in particular a high level of operating comfort and/or a long-lasting design and/or a high level of functionality can be achieved.

The insulation unit could, for example, be designed asymmetrically, for example with respect to a center point and/or center of gravity of the insulation unit. In particular, the household appliance device could, in particular in the case of an asymmetric insulation unit, have at least one second insulation unit, which could be designed identically to the insulation unit. In particular, the insulation unit and the further insulation unit could be arranged rotated relative to one another at least in a disassembled state and in the case of an overlapping arrangement of the insulation unit and the second insulation unit, for example by rotating the second insulation unit, in particular about an axis of rotation which is aligned perpendicular to the second insulation unit and runs through a center point and/or center of gravity of the second insulation unit, by an angle of at least substantially 90° and/or of 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 overlapping. 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 overlapping. This could in particular enable low storage and/or a low variety of components.

Preferably, the insulation unit and/or the further insulation unit is designed symmetrically, whereby in particular a 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 could in particular 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 could in particular be provided for modular assembly. Preferably, the insulation unit is 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. The term "in one piece" should in particular be understood as at least materially connected, for example by a welding process, an adhesive process, an injection molding process and/or another process that appears to be useful to the person skilled in the art, and/or advantageously formed in one piece, such as by production from a cast and/or by production in a single or multi-component injection molding process and advantageously from a single blank. This makes it possible to achieve a stable construction and/or simple manufacture of the insulation unit and/or the further insulation unit. In particular, low storage requirements and/or a low variety of components can be achieved.

It is further proposed that the insulation unit and in particular the further insulation unit have at least one first insulation part element and at least one second insulation part element, which are provided for modular assembly. In particular, the further insulation unit has at least one further first insulation part element and at least one further second insulation part element, which are provided in particular for modular assembly. The phrase that a first object and a second object are provided for "modular" assembly is to be understood in particular to mean that the first object and the second object are provided for assembly in a modular and/or building block manner and are in particular designed in such a way 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 makes it possible in particular to enable a particularly flexible design.

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

It is also proposed that the insulation unit and/or the further insulation unit consist/consists at least to a large extent of mica, in particular of synthetic mica. As a result, the insulation unit and/or the further insulation unit can consist in particular at least to a large extent of a material with an optimized price-performance ratio, which in particular can enable a high level of economic efficiency.

Insulation between the first structural unit and the second structural unit can be perfected in particular 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 safety and/or high functionality can be achieved in particular 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 one first structural unit and at least one second structural unit, wherein for the purpose of laying the insulation unit an external shape of the insulation unit is adapted to the first structural unit, and wherein a thermal expansion of at least a partial region of the insulation unit is at least substantially compensated.
