Description

State of the art

The invention relates to a household appliance device according to the preamble of claim 1 and a method for assembling a household appliance device according to the preamble of claim 13.

A household appliance device is already known from the prior art, which has a carrier unit for an electronics unit and a strain relief unit for a power supply cable. In this case, the strain relief unit is a component that is formed separately from the carrier unit.

The object of the invention is in particular to provide a generic device with improved properties in terms of construction. The object is achieved according to the invention by the features of claims 1 and 13, while advantageous configurations and developments of the invention can be found in the dependent claims.

Advantages of the Invention

The invention is based on a household appliance device, in particular a hob device, with at least one support unit, which is intended to carry at least one electronic unit, and with at least one strain relief unit, which is intended to hold at least one cable, in particular a power supply cable, in an assembled state , to fix tightly.

It is proposed that the carrier unit is formed at least partially and preferably completely in one piece with the strain relief unit.

A construction can advantageously be improved by such a configuration. In particular, assembly can be simplified, as a result of which errors can be minimized and/or costs reduced. In addition, complexity can be reduced since additional structural units for guiding and fixing the cable can be dispensed with, which in turn can make lower costs possible. A high level of security can also be ensured by means of the strain relief unit, in which case the cable can be fixed in a tension-resistant manner and, in particular, a permanent connection to the electronics unit can be made possible. In particular, damage to the cable and other structural units, in particular the electronics unit, can be avoided as a result. In addition, uncontrolled removal, in particular tearing out, of the cable from the domestic appliance device can be prevented. In this way, in particular, short circuits can be avoided, which can lead to considerable damage at least to the electronics unit.

The household appliance device, in particular the hob device, is a subassembly of a household appliance, in particular a hob, in an installed position. However, it would also be conceivable for the household appliance device to encompass the entire household appliance, in particular the entire hob. The household appliance could be an oven and/or a steam appliance and/or a washing machine, for example. The domestic appliance is preferably a hob designed as an induction hob.

The carrier unit could consist, for example, at least partially and preferably at least to a large extent of a plastic and/or metal and/or a composite material. The carrier unit is intended to carry and/or hold a weight exerted by the electronic component, in particular the electronics unit, in at least the assembled state and to attach this weight to at least one further structural unit, for example an outer housing element of the household appliance device, in particular to a hob housing of the Hob to transfer. In particular, the carrier unit is arranged in an interior space, between a mounting plate, in particular a hob plate, of the hob and the hob housing. For this purpose, the carrier unit has at least one receiving space and/or at least one support surface for receiving and/or supporting at least a partial area, preferably the entire electronic unit.

In particular, the electronics unit is part of the household appliance device. The electronics unit is an electrical and/or electronic unit, which preferably has at least one printed circuit board and is provided for generating and/or processing and/or forwarding electrical currents and/or electrical signals. For example, the electronics unit could be provided as a control unit and/or a supply unit, in particular a power unit, and/or an operating unit, in particular for controlling and/or supplying and/or operating the household appliance, in particular the hob. In at least one installation position and/or the assembled state, the electronics unit is arranged on the support unit below the mounting plate and inside the interior.

The mounted state mentioned is a state in which the strain relief unit and/or the carrier unit are mounted in and/or on the outer housing element and the cable is fixed in a tension-resistant manner by means of the strain relief unit and/or in particular electrical contact is made with at least the electronics unit forms. In particular, the cable is part of the household appliance device. During assembly, the cable is inserted into the strain relief unit in one method step and then fixed in a tension-resistant manner, so that at least one strain relief is provided for the cable in the assembled state.

In the mounted state, the strain relief unit fixes the cable in a tensile and/or preferably additionally non-rotatable manner. Here, the strain relief unit forms at least one strain relief for the cable. In the installed state, the cable can preferably be moved along its longitudinal direction by a maximum of 1 cm, in particular by a maximum of 0.5 cm and particularly preferably by a maximum of 0.1 cm. The cable could also be fixed in a rotationally fixed manner. A rotational movement of the cable in the installed state and in a region of the strain relief unit is preferably possible, in particular by at most 10°, preferably by at most 5° and particularly preferably by at most 1°. In particular, a torque, in particular a moment of force, of the cable, for example caused by an external force, could be blocked. In particular, the cable could be fixed in a non-positive and/or positive manner in at least one longitudinal and/or one transverse direction of the cable. In the mounted state, the cable could only by a significantly strong external force back out of the strain relief unit must be removed. In particular, the strain relief unit prevents uncontrolled detachment and/or removal of the cable by means of the tensile and/or non-rotatable fixation.

The cable could be a mains cable and/or a power supply cable and be provided, for example, for a power supply of the electronic component, for example a heating element and/or a blower unit of the household appliance, in particular the hob, preferably the electronics unit. It would also be conceivable for the cable to be in the form of a data cable and/or a network cable. For example, in the cable, several cores are bundled together to form a thick cable strand that defines the cable.

The strain relief unit can preferably be used for cables with different diameters. In this case, the strain relief unit could consist, for example, at least partially and preferably at least to a large extent of a plastic and/or a metal and/or a composite material. In particular, the strain relief unit is made from the same material and/or the same composite material as the carrier unit. In this case, the strain relief unit could be designed in several parts, with individual structural units of the strain relief unit being connected to one another and/or fastened to one another. The strain relief unit is preferably designed in one piece. The strain relief unit is particularly preferably designed in one piece with the carrier unit. The fact that the carrier unit is formed "at least partially in one piece" with the strain relief unit should be understood to mean that at least one element of the strain relief unit is formed and/or connected in one piece with the carrier unit. The entire strain relief unit is preferably designed in one piece with the carrier unit. "In one piece" is to be understood as being at least cohesively connected, for example by an adhesive process, a welding process, an injection molding process and/or another process that a person skilled in the art considers appropriate, and/or formed in one piece, for example by manufacture in a single or multi-component injection molding process and/or by production from a single cast and/or from a stamping process from a single blank.

“Provided” here and in the following is to be understood to mean specially programmed, designed and/or equipped. The fact that an object is provided for a specific function should be understood to mean that the object fulfills and/or executes this specific function in at least one application and/or operating state.

It is also proposed that the strain relief unit has at least one strain relief element which can be pivoted from at least a first pivot position into at least a second pivot position and is intended to fix the cable in the second pivot position in cooperation with a further strain relief element of the strain relief unit. As a result, a construction can be further improved, in particular with regard to faster and simpler assembly. In addition, a fixation, in particular a method step during assembly to a fixation, of a cable can be advantageously simplified, in particular by a pivoting movement of the strain relief element. In addition, additional structural units for fixing the cable, for example screws and/or a terminal strip, can be dispensed with.

The strain relief element is connected to the further strain relief element in particular by means of a hinge of the strain relief unit. Here, the hinge could be a separable or an inseparable hinge. It would be conceivable for the hinge to be a rolled hinge, with the strain relief element and the further strain relief element being connected to an in particular non-detachable pin of the hinge. Alternatively, one of the strain relief elements could have a hinge pin and the other strain relief element could have a hinge pin receptacle. For example, the strain relief element and the further strain relief element could be rotatably movable relative to one another. The further strain relief element is preferably immovable and is in particular formed in one piece with the carrier unit. Preferably, only the strain relief element can be pivoted relative to the carrier unit. The strain relief element is also particularly advantageously connected in one piece to the further strain relief element, in particular via a film hinge.

The first and the second pivoting position indicate, in particular, possible positions of the strain relief element. The first pivoting position is in particular an initial state of the strain relief element, preferably a stop position of the strain relief element, in particular a maximum opening of the hinge. In the first pivoting position, in particular in the unassembled state, an angle between the strain relief element and the further strain relief element is in particular at least 90°, preferably at least 120° and particularly advantageously at least 160°. In particular, in the first pivoting position, in particular in the unassembled state, the strain relief element and the further strain relief element are arranged parallel next to one another and in the same plane, in particular in the main plane of extension of the carrier unit. In the assembled state, the strain relief element is in a second pivoting position relative to the further strain relief element. In order to position the strain relief element from the first pivoting position to the second pivoting position during assembly, the strain relief element must be pivoted by at least 90°, preferably by at least 120° and particularly preferably by at least 150° in one method step.

In particular, the second pivoting position is present in the assembled state. In this case, the cable is arranged and/or clamped between the strain relief element and the further strain relief element. In particular, the cable is enclosed on at least two sides, namely fixed in a tensile and/or non-rotatable manner. For this purpose, the cable is laid in at least the installed state in the additional strain relief element and/or restricted along at least the transverse direction of the cable by means of the strain relief element and the additional strain relief element. In particular, the strain relief element prevents movement of the cable in the longitudinal and/or the transverse direction. During assembly, after the cable has been inserted, in particular into the further strain relief element, in a further method step the strain relief element is pivoted towards the further strain relief element until the strain relief element fixes the cable. In the installed state, the cable is fixed in a tension-resistant manner by means of the strain relief element and the further strain relief element.

Furthermore, it is proposed that the strain relief unit has at least one fixing element, by means of which the strain relief element can be fixed at at least two different distances relative to the further strain relief element. As a result, a construction can be further increased in terms of flexibility. In particular, a fixation and/or strain relief of a cable can be flexibly adapted to a diameter of the cable. Especially with one as a power supply cable trained cable can be present significantly different diameters of the cable, so that an individual fixation for the cable can be made possible by means of the fixing element. In particular, by means of at least two pawls of the fixing element, at least two different distances can be set and thus a finer adjustment to the diameter of the cable can be achieved. This can also provide improved security with regard to a more stable fixation of the cable.

For example, the cable could be fixed in a non-positive and/or positive manner to the further strain relief element by means of a metal clamp of the strain relief unit. In particular, any number of distances can be set and/or a stepless fixation of the cable by means of the strain relief element is conceivable. The strain relief element could be fixed to the further strain relief element by means of a plug-in or screw connection, preferably with a latching connection. In the assembled state, in particular in the second pivoting position, the strain relief element is fixed to the fixing element. The fixing element is arranged on the further strain relief element and is at least intended to fix and/or position the strain relief element at at least two different distances, in particular in two different second pivot positions, relative to the further strain relief element. The distance depends on at least one pivoting movement of the strain relief element.

The fixing element particularly preferably has at least one pawl. In the assembled state, in particular in one of the second pivot positions, the pawl is provided to prevent a reverse movement of the strain relief element, in particular a pivot movement of the strain relief element into the first pivot position. However, it would be conceivable that a forward movement of the strain relief element, in particular from the second pivoting position into a further second pivoting position and thus an approach of the strain relief element to the further strain relief element, starting from the first pawl into a further pawl of the fixing element is possible. In this case, the further pawl could be arranged in a different plane relative to the pawl with regard to the pivoting movement of the strain relief element. This results in at least two different distances, in particular two different second pivot positions, of the strain relief element to the further strain relief element, in which the strain relief element can be fixed. The pawl and the further pawl could be arranged one below the other with regard to the pivoting movement of the strain relief element. The pawl and the further pawl are preferably arranged offset to one another on different levels. During assembly, in a further method step, pressure is exerted on the strain relief element and/or in particular on the cable, so that the strain relief element is fixed with at least one of the pawls. In the assembled state, the strain relief element is fixed in particular in a non-positive manner with at least one of the pawls.

It is also proposed that the strain relief element has a predetermined breaking point which is unbroken in an unassembled state and broken in at least the assembled state, in particular in at least one preassembled state. The design and safety can be further increased by means of the predetermined breaking point, since prior use of the strain relief unit can be clearly shown to a fitter. In addition, safety can be increased to the effect that the strain relief unit can be secured in the unmounted state after a manufacturing process and during transport up to a first use and/or assembly.

The unassembled state describes a state directly after a manufacturing process for the strain relief unit and/or the carrier unit. In particular, in contrast to the unassembled state, the carrier unit and/or the strain relief unit is/are arranged on and/or in the outer housing element in a preassembled state. With regard to a time course, in particular with regard to at least one method step during assembly, the pre-assembled state is after the unassembled state and before the assembled state. In the pre-assembled state, for example, the cable could already be inserted into the additional strain relief element. Alternatively and/or additionally, the electronics unit could be carried by the carrier unit in the preassembled state. In the unassembled state, the strain relief element is in the first pivoting position. In particular, the strain relief element is in the preassembled state between the first pivoting position and one of the second pivoting positions. In an assembly in one step from the unassembled state to the pre-assembled state, the strain relief pivoted from the first pivot position. The predetermined breaking point is intended to indicate, in particular for the installer, that the strain relief unit has been used before and/or that it has already been installed. If the predetermined breaking point is unbroken, the strain relief unit is in particular unused and is in an unassembled state. In particular, in the first pivoting position, the predetermined breaking point is unbroken. If the strain relief unit is installed in at least one method step during assembly, the predetermined breaking point is broken and the strain relief element is pivoted out of the first pivoting position.

In a further embodiment of the invention, it is proposed that the domestic appliance device has a component on which the strain relief unit and/or the carrier unit is arranged in at least one pre-assembled state. As a result, assembly can be further simplified, in particular with regard to complexity, and/or an inexpensive assembly step can be achieved.

The component could be, for example, a panel and/or a wall of the household appliance, in particular a cooktop housing. It would be conceivable that the component is a bottom of the hob housing and delimits an interior space. In particular, the component delimits the strain relief unit and/or the carrier unit in at least the pre-assembled state. In the preassembled state and/or in the assembled state, the strain relief unit and/or the carrier unit are arranged on the component.

In addition, it is proposed that the strain relief unit and in particular the strain relief element has at least one poka-yoke element on a side facing the component, which poka-yoke element is present on the component in the preassembled state. In this way, construction can be simplified and safety can be maximized, since the Poka-Yoke element can be used to alert an installer to incorrect assembly and/or use of the strain relief unit. In addition, incorrect assembly can be avoided. In addition, the poka-yoke element can prompt a fitter to carry out a further method step when assembling the strain relief unit, in particular to fix the cable.

The poka-yoke element is an element aligned at least essentially perpendicular to a main plane of extension of the strain relief element. The poka-yoke element protrudes beyond the main plane of extent of the strain relief element, in particular beyond the main plane of extent of the entire strain relief unit.

If the strain relief unit is arranged on the component, in particular the interior, during assembly, the poka-yoke element stands up on the component, considerable pressure being exerted on the strain relief element, so that the predetermined breaking point breaks and the strain relief element is pivoted out of the first pivoting position becomes. In particular, the poka-yoke element blocks the strain relief element from pivoting back into the first pivot position. The poka-yoke element standing on the component specifies in particular at least one sequence for at least two subsequent method steps during assembly, specifically in particular a possible pivoting direction of the strain relief element. A correct and secure fixation for the cable will only then be possible if the poka-yoke element is removed from the component in a further method step during assembly, in particular the strain relief element is pivoted into at least one of the two pivot positions. In a further method step during assembly, the strain relief element must preferably be pivoted into one of the second pivot positions.

In addition, it is proposed that the domestic appliance device has an outer housing element which accommodates the carrier unit and/or the strain relief unit in at least the assembled state, in particular in the preassembled state. As a result, a compact and safe home appliance device can be provided. In particular, manufacturing costs can be reduced and assembly can be simplified.

In at least the assembled state, and in particular also the preassembled state, the outer housing element is intended to accommodate the carrier unit and/or the strain relief unit, for example at least partially and preferably at least to a large extent, particularly preferably completely. “Receive” is to be understood in particular as meaning that the outer housing element at least partially and preferably at least to a large extent encloses and/or delimits the carrier unit and/or the strain relief unit. For example, the outer housing member identical to the hob housing, so that the outer housing element could at least partially define the interior. In particular, the outer housing element and the mounting plate delimit the interior space in which at least the carrier unit and/or the strain relief unit are arranged in at least the assembled state, in particular in at least the preassembled state. The outer housing element has at least one wall and at least one floor. It would be conceivable that the ground is the same as the component. The outer housing element could consist, for example, at least partially and preferably at least to a large extent of a metal and/or a composite material.

If the outer housing element has the component and the strain relief element protrudes beyond the outer housing element in the preassembled state, incorrect assembly of at least the strain relief unit can be avoided for a fitter in the preassembled state and an improved construction with regard to simpler and safer assembly can thus be provided.

In particular, if the strain relief element protrudes, it could prevent the mounting plate from being arranged on the outer housing element. “Protrudes” is to be understood in particular as meaning that the strain relief element, in the preassembled state, extends beyond a highest point of the outer housing element with respect to a distance from the component. In particular, an end point of the strain relief element is at a greater distance from the component than the highest point of the outer housing element. For example, in the preassembled state, the strain relief element protrudes beyond the outer housing element by at least 2%, advantageously at least 5%, particularly advantageously at least 10% of an extension of the strain relief element in a mounting plane aligned essentially perpendicularly to the component. In this case, the strain relief element is in the preassembled state between the first and the second pivoting position.

In a further embodiment of the invention it is proposed that the strain relief unit defines at least one labyrinth mount for the cable. In this way, a particularly advantageous and simple assembly can be achieved and manufacturing costs can be reduced. In addition, additional structural units and an additional screw connection for fixing the cable can be dispensed with.

In particular, the strain relief element and/or the further strain relief element have parts of the labyrinth receptacle. The labyrinth receptacle specifies a course for the cable in at least the pre-assembled state. The labyrinth receptacle, in particular the strain relief element and/or the additional strain relief element, defines at least one receptacle area for the cable with two opposite curvatures, so that the inserted cable preferably takes an S-shaped course. In addition, the labyrinth receptacle can have a number of anti-slip elements. The anti-slip elements can be felt pads and/or self-adhesive elements, for example. The anti-slip elements are preferably elevations on the strain relief element and/or the further strain relief element, which are arranged at a regular distance along the course of the labyrinth receptacle. In particular, the anti-slip elements are each arranged on a side facing the other strain relief element on the strain relief element and/or the further strain relief element. The anti-slip elements fix the cable in at least the assembled state in a non-slip and/or tensile manner. It would be conceivable that the labyrinth receptacle, in particular the further strain relief element, alternatively and/or additionally has positioning elements which fix and/or position the cable in the course. In this case, the positioning elements could be arranged on opposite sides of the cable on the further strain relief unit. Corresponding to the positioning elements of the further strain relief unit, the strain relief unit could have openings which accommodate the positioning elements in the installed state, in particular one of the second pivot positions. In particular, the cable must be arranged, in particular guided, around the positioning elements. If the cable is inserted into the further strain relief element during assembly, the cable is adapted to a shape of the labyrinth receptacle. In at least the assembled state, the cable follows the course of the labyrinth receptacle.

In a further aspect of the invention, which can be considered in particular on its own, it is proposed that the outer housing element has at least one opening in which a cable bushing element of the strain relief unit for guiding the cable out of the outer housing element is arranged. A simpler construction and improved safety can thus be provided, since the cable can be guided out of the outer housing element in particular without being damaged can. The cable feed-through element can be used to prevent the cable from coming into contact with a sharp outer edge of the outer housing element, in particular damage to the cable by the outer edge. In addition, assembly can be further simplified since the cable bushing element can be inserted into the opening and additional cable routing elements and elements for stabilizing the cable can thus be dispensed with.

It would be conceivable that several components, in particular cable routing elements, of the strain relief unit and/or of the outer housing element are provided for guiding the cable out of the outer housing element. Preferably, the strain relief unit has only one cable feedthrough element which, at least in the assembled state, acts as a feedthrough aid and/or insertion element for the cable. It would also be conceivable for the cable feedthrough element, in the preassembled state, to guide the cable laid into the further strain relief element out of the outer housing element, in particular the strain relief unit and/or the opening. The outer housing element could have at least one wall. The opening could be inside the wall. Alternatively, the opening could extend over at least one further wall of the outer housing element. The opening preferably extends over exactly two walls of the outer housing element. The cable bushing element is in particular adapted to a shape of the opening. In particular, the opening and the cable bushing element have an identical shape. For example, the opening and/or the cable bushing element could have a triangular shape. The opening is preferably round and/or adapted to a shape and/or the diameter of the cable. In particular, the cable bushing element extends over the wall and the further wall. If the cable is fixed in a tension-resistant manner during assembly in the strain relief unit, in a further and/or identical method step the cable is routed out of the outer housing element through the cable bushing element.

In addition, it is proposed that the cable feedthrough element extends over at least one edge of the outer housing element. In this way, a construction can be improved even further in terms of quick and simple assembly, since the cable can be flexibly routed out of the outer housing element in at least two different directions. Here, the direction of the running cable be adapted to further use of the cable and/or an installation position of the household appliance device, in particular an installation position of the household appliance.

The edge forms a particular stop of the wall and the further wall. In particular, the wall and the further wall are preferably arranged perpendicular to one another at the edge, with an angle between the wall and the further wall in the assembled state being in particular at most 5°, preferably at most 2° and particularly advantageously at most 1° from one right angle deviates. The edge could, for example, be an outer edge of the outer housing element, in particular the hob housing. In particular, the edge is sharp and pointed and could, for example, damage the cable in the assembled state. The inserted cable feedthrough element preferably protects the cable from the edge. By means of the cable feedthrough element extending over the edge, the cable could be routed out in a direction parallel to the main plane of extension of the carrier unit and/or strain relief unit, in particular starting from a main plane of extension of the outer housing element. Alternatively, the cable could also be led out in a direction perpendicular to the main plane of extension of the carrier unit and/or strain relief unit, in particular starting from the main plane of extension of the outer housing element.

In addition, the invention is based on a method for assembling a household appliance device, wherein the household appliance device has at least one carrier unit which is intended to carry at least one electronic unit, and has at least one strain relief unit which is at least partially formed in one piece with the strain relief unit and by means of which in an assembled state at least one cable, in particular a power supply cable, is fixed in a tension-proof manner.

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

Description of the embodiment

figure 1 shows a domestic appliance 10 designed as a hob with a domestic appliance device 12, which is designed as a hob device, in a view from below. The household appliance 10 has a hob plate designed as a set-up plate 48 . In this case, the mounting plate 48 is provided for mounting a cooking utensil (not shown). The domestic appliance 10 has a plurality of heating elements (not shown), which are provided for the purpose of heating the cooking utensil placed on the support plate 48 . The household appliance device 12 has an outer housing element 38 which, together with the mounting plate 48 , defines and delimits an interior space for accommodating at least one electronic component of the household appliance 10 .

The outer housing element 38 is essentially square in shape with at least one wall 56 and a further wall 58 which forms a bottom of the outer housing element 38 (cf. figure 8 ). However, different forms are also conceivable. The wall 56 and the further wall 58 are arranged perpendicular to one another. Here, a stop of the wall 56 with the further wall 58 forms an edge 46 of the outer housing element 38. The walls 56, 58 have an opening 42 which extends over the wall 56 and the further wall 58. The opening 42 extends over the edge 46.

At least one strain relief unit 18 of the household appliance device 12 is arranged in the interior space within the outer housing element 38 in at least one assembled state (cf. figure 8 ). The strain relief unit 18 has a cable bushing element 44 . The cable feed-through element 44 is adapted in shape and size to the opening 42 and is inserted into the opening 42 . In this exemplary embodiment, the cable feedthrough element 44 extends over the edge 46 and thus also over the wall 56 and the further wall 58.

The household appliance device 12 has a cable 20 . The cable 20 designed as a power supply cable bundles several wires together to form a thick cable harness.

The strain relief unit 18 is provided for fixing the cable 20 with high tensile strength. In the installed state, the cable 20 is fixed in a tension-resistant manner in the interior space within the outer housing element 38 by means of the strain relief unit 18 (cf. figure 9 ). The opening 42 is provided for cable routing out of the outer housing member 38 . The cable feedthrough element 44 guides the cable 20 in the installed state out of the strain relief unit 18 and the outer housing element 38 through the opening 42.

In the Figures 2 and 3 are detailed views of the opening 42 and the cable feed-through element 44 with different cable guides in the assembled state. To figure 2 the cable bushing element 44 guides the cable 20 along a direction perpendicular to a main extension plane of the carrier unit 14 and/or strain relief unit 18 and essentially perpendicular to the wall 58 of the outer housing element 38. Alternatively, FIG figure 3 that the cable 20 is guided out of the outer housing element 38 through the opening 42 in a direction parallel to a main extension plane of a component 34 of the household appliance device 12 , specifically perpendicular to the wall 56 .

the figures 4 and 5 show an unassembled state of the household appliance device 12. The figure 4 shows the household appliance device 12 with at least the strain relief unit 18 in a plan view. In addition, the household appliance device 12 has a carrier unit 14 . The carrier unit 14 is at least partially in one piece with the strain relief unit 18 trained. In this exemplary embodiment, the carrier unit 14 and the entire strain relief unit 18 are designed in one piece. The carrier unit 14 and the strain relief unit 18 are manufactured from a blank in a manufacturing process. the figure 4 shows that the carrier unit 14 has at least one receiving area and/or at least one support surface. In this case, the carrier unit 14 comprises a plurality of insert elements which at least define the receiving area. The insert elements are not discussed in further detail below. The carrier unit 14 is intended to carry at least one electronics unit 16 . In at least one preassembled state, the carrier unit 14 carries the electronics unit 16. In this case, the electronics unit 16 can be arranged in the receiving area and/or at least on the support surface (cf. figure 8 ).

The strain relief unit 18 has at least one strain relief element 22 . In the unassembled state, the strain relief element 22 is in a first pivoting position 26 (cf. figure 4 or 5 ). In addition, the strain relief unit 18 has a further strain relief element 24 . The additional strain relief element 24 is connected to the carrier unit 14 in one piece. In this exemplary embodiment, the strain relief element 22 and the further strain relief element 24 are designed in one piece. In the unassembled state, the strain relief element 22 and the further strain relief element 24 are arranged parallel to one another and within the same horizontal plane of extension of the strain relief unit 18 . In this case, the strain relief element 22 and the further strain relief element 24 are connected to one another via a hinge 60 . The hinge 60 is provided to pivot the strain relief member 22 . In the preassembled state, the strain relief element 22 pivots from the first pivot position 32 by means of the hinge 60 out of the first pivot position 26 (cf. Figures 12 and 13 ). the Figures 12 to 14 show, in addition to a second pivoting position 28 in the assembled state, further pivoting positions of the strain relief element 22 in the preassembled state.

The strain relief element 22 has a predetermined breaking point 32 . The predetermined breaking point 32 is unbroken in the unassembled state (cf. figure 4 ). In the unassembled state, the predetermined breaking point 32 fixes the strain relief element 22 in the first pivoting position 26.

To relieve the strain on the cable 20, the strain relief unit 18 defines a labyrinth receptacle 40 for the cable 20. The strain relief element 22 and the further strain relief element 24 have parts that define the labyrinth receptacle 40. The labyrinth mount 40 specifies a course for the cable 20 . The labyrinth receptacle 40 has several elevations 62 (cf. figure 6 ). The elevations 62 are identical to one another, which is why only two elevations 62 are provided with a reference number. In the detail view in figure 6 it can be seen that the elevations 62 are arranged on the strain relief element 22 and the further strain relief element 24 . In at least the preassembled state, the cable 20 lies on the elevations 62 (cf. figure 8 ). The elevations 62 fix the cable 20 at least in a non-slip manner. In this exemplary embodiment, the course of the labyrinth receptacle 40 has at least two opposite curvatures (cf. figure 6 ). In order to fix the cable 20 in the course, the labyrinth mount 40 has at least one positioning element 64 . The positioning element 64 is round. Alternatively, the positioning element 64 has a tip 66 . Furthermore, the labyrinth receptacle 40 has a further positioning element 68 . The additional strain relief element 24 has the positioning element 64 and the additional positioning element 68 . In this exemplary embodiment, the positioning element 64 and the further positioning element 68 have different shapes. In at least the preassembled state, the cable 20 lies against the positioning elements 64, 68 (cf. figure 8 ). Here, the tip 66 of the positioning element 64 and the further positioning element 68 touch the cable on opposite sides (cf. figure 8 ). The strain relief unit 22 has at least one opening 74 . The opening 74 is adapted to a shape and size of the positioning elements 64, 68. In the mounted state, the opening 74 accommodates the positioning element 64 and/or the further positioning element 68 (cf. figure 9 ).

the figure 5 shows a view of the household appliance device 12, rather a detailed view of the strain relief unit 18 in an unassembled state in a bottom view. The strain relief unit 18 has at least one poka-yoke element 36 . The poka-yoke element 36 is arranged perpendicular to a main extension plane of the strain relief unit 18 . In the first pivoting position 26, the poka-yoke element 36 extends perpendicular to the strain relief element 22 over an extension plane of the strain relief element 22.

In the preassembled state, the strain relief unit 18 is arranged on the component 34 (cf. figure 6 ). Here, the predetermined breaking point 32 is broken. As soon as the strain relief unit 18 is arranged on the component 34 in a method step during assembly, the predetermined breaking point 32 breaks and the strain relief element 22 pivots out of the first pivot position 26 due to the poka-yoke element 36. This is on a side facing the component 34 of the strain relief element 22 arranged poka-yoke element 36 on the component 34 (cf. figure 7 ). Furthermore, the strain relief element 22 protrudes beyond the outer housing element 38 in the preassembled state. In the preassembled state, the strain relief element 22 is located between the first pivot position 26 and the second pivot position 28.

the figure 8 shows the pre-assembled state of the household appliance device 12 in a plan view. The carrier unit 14 carries the electronics unit 16. In addition, the carrier unit 14 carries other components of the household appliance device 12. The cable 20 is inserted into the strain relief unit 18. The cable 20 is connected to at least the electronics unit 16 .

In the mounted state, the strain relief element 22 and the further strain relief element 24 are arranged at least essentially parallel one above the other (cf. figure 9 ). The strain relief element 22 is in the second pivoting position 28 with regard to a plan view, directly above the further strain relief element 24. In the assembled state, the cable 20 is fixed in a tension-resistant manner by means of the strain relief element 22 and the further strain relief element 24. the figure 9 shows a schematic course of the fixed cable in a plan view of the strain relief element 22 .

The strain relief unit 18 has a fixing element 30 . the Figures 10 and 11 show that the strain relief element 22 can be fixed relative to the further strain relief element 24 at at least two different distances on the fixing element 30. The fixing element 30 has at least one pawl 70 . Furthermore, the fixing element 30 has a further pawl 72 . The pawl 70 and the further pawl 72 are arranged on different levels with respect to a pivoting movement of the strain relief element 22 relative to one another. In this exemplary embodiment, the pawl 70 and the further pawl 72 are offset from one another on different levels arranged. The strain relief element 22 is fixed in a first position at a first distance relative to the further strain relief element 24 in the mounted state on the first pawl 70 (cf. figure 10 ). the figure 11 shows that the strain relief element 22 can also be fixed at a second distance relative to the further strain relief element 24 in the mounted state on the second pawl 72. The pawl 70 and the further pawl 72 are provided to fix the strain relief element 22 depending on a diameter of the cable 20 .

the Figures 12 to 14 show the strain relief element 22 in different pivot positions relative to the further strain relief element 24. The Figures 12 and 13 represent the pre-assembled state. In this case, the strain relief unit 18 is arranged on the component 34 and the strain relief element 22 is pivoted out of the first pivoting position 26 . The cable 20 has already been inserted into the additional strain relief element 24 . the figure 12 shows the pending poka-yoke element 36 on the component 34 and the strain relief element 22 pivoted up figure 13 is a further pivoting position of the strain relief element 22 after at least one method step during assembly starting from the preassembled state in figure 12 shown. This in figure 13 Strain relief element 22 shown is folded to the further strain relief element 24 and touches at least partially the cable 20. In the figure 14 the assembled state with the fixed cable 20 and the strain relief element 22 in the second pivoting position 28 can be seen.
