[0003] Household appliance with a treatment container

[0004] The invention relates to a household appliance with a treatment container, wherein at least one force absorber is arranged between supporting parts of the household appliance and a packaging that encloses the household appliance at least on one side.

[0005] The household appliance can be, for example, a large household appliance, such as a household dishwasher with a dishwashing container for holding dishes, a household washing machine with a washing drum for holding laundry, a household dryer with a drying drum for holding damp textiles, or a household stove with a baking oven for holding food.

[0006] Such household appliances are typically packaged in a box where the lid and base consist of a pallet-like wooden frame with a cardboard lid placed over them. The top and bottom edges of the goods are protected by cushioning elements, usually made of expanded polystyrene (EPS), positioned between the frame and the goods. The long edges of the goods are also protected by similar foam elements, into which wooden slats are inserted to act as spacers for the frame and to stiffen the cushioning elements. The entire packaging unit is held together with straps and covered with a film, usually shrink film.

[0007] This packaging is very elaborate and expensive, consisting of many different parts, most of which are not reusable and from which the majority of the materials used cannot be recycled. The sheer number of large parts makes return shipping practically impossible for the user or buyer of the packaged household appliance, leaving them ultimately responsible for disposing of the packaging.

[0008] When packaging household appliances of the aforementioned type with the aforementioned packaging, the parts of the packaging must be the large ones, in the case of 202500187

[0009] - 2 -

[0010] Forces occurring during machine handling, storage, and transport, such as clamping forces when using standard clamp stackers and stacking forces, cannot be absorbed by the machine alone, as the typically very thin side walls of a household appliance housing of the type mentioned above have low load-bearing capacity and there is a risk that they will be plastically deformed when forces are transferred to the packaged household appliance.

[0011] The main function of a force transducer is therefore to detect and / or transmit forces between elements of the appliance's packaging and the appliance itself. For this purpose, sufficiently large contact areas between the force transducer and the packaging are required, depending on the packaging material, to ensure that a material-specific, and in particular maximum permissible, surface pressure is not exceeded.

[0012] German patent application DE 4446961 A1 discloses a household appliance with a treatment container, wherein large-area force-absorbing elements are arranged between load-bearing parts of the household appliance and packaging that encloses the household appliance on at least one side. The force-absorbing elements can be made of plastic in one piece. Furthermore, the force-absorbing elements can be arranged between a frame of the household appliance and / or the treatment container and adjacent side walls of the household appliance. Additionally, the force-absorbing elements can be arranged in the outermost upper corners of the side walls of the household appliance and on the outermost lower edges of the side walls of the household appliance at a distance from a mounting surface.

[0013] Such a standardized force-absorbing component must be designed and dimensioned to accommodate all possible packaging materials and concepts, especially material combinations. Therefore, in household appliances, where a smaller force-absorbing component would suffice, it leads to unnecessarily high material usage.

[0014] Furthermore, when using sustainable packaging materials, such as cardboard with honeycomb structures, the largest possible contact surfaces are required, as the packaging components will fail if the local surface pressure is too high.

[0015] - 3 -

[0016] This may occur even before the force to be transmitted, such as in clamping, is fully generated. Consequently, in the logistics of household appliances, a certain minimum force, particularly clamping force, must be able to be generated to produce sufficient friction / holding force. Furthermore, certain packaging concepts using sustainable packaging materials are only employed in small quantities to specifically meet customer- or country-specific requirements.

[0017] Against this background, one object of the present invention is to provide an improved household appliance. In particular, a household appliance is to be created in a simple manner which enables the use of technically improved packaging.

[0018] To solve the problem according to the invention, a household appliance with a treatment container is proposed, wherein at least one force transducer is arranged between supporting parts of the household appliance and a packaging enclosing the household appliance at least on one side, wherein at least one force transducer comprises at least two components, wherein one component is a base part arranged on a supporting part and at least one further component is an additional part, and wherein the at least one additional part is preferably detachably connectable to the base part.

[0019] According to the invention, the force transducer comprises at least two components, one of which is a base part arranged on a load-bearing part, and at least one further component is an accessory part, wherein the at least one accessory part is preferably detachably connectable to the base part. Thus, in addition to the base part arranged on the load-bearing part, two or more flexibly deployable accessory parts can be provided. A mounting device for the force transducer, such as a screw, a clip, a cable tie, an adhesive, or the like, is not considered a separate component or accessory part within the scope of this disclosure.

[0020] According to the disclosure, the term "connectable" means any form-fit and / or force-fit connection between two components, for example, between the base part and at least one additional part. Generally, according to 202500187

[0021] - 4 -

[0022] Duden defines "verbindbar" as an adjective with the following meaning: "that which can be connected, that which can be connected".

[0023] By attaching force-bearing components to the existing load-bearing parts of the household appliance according to the invention, the large forces occurring during mechanical handling, storage, and transport, particularly the clamping forces exerted by the parts of the appliance, are transferred. This creates a simple household appliance that allows for the use of more cost-effective packaging, as the packaging itself does not have to bear these forces. In practice, it has been shown that the packaging of the household appliance according to the invention can, in particular, eliminate the need for the aforementioned wooden slats and stands, resulting in a significant reduction in packaging costs and sparing the user or buyer of the packaged household appliance the return shipping or disposal of large packaging components.

[0024] The additional part can be connected to the base body in a simple, linear assembly step, preferably in a detachable manner, while the base body is already installed and fixed to the household appliance.

[0025] The two- or multi-part force transducer can be adapted and extended to meet specific variant requirements by adding at least one additional component to accommodate the necessary dimensions and mechanical demands during machine handling, storage, and transport. This results in the advantages of resource-efficient material use across the entire product portfolio, flexible adaptation to different tasks and requirements, and flexible compatibility with various packaging. Furthermore, the two- or multi-part design of the force transducer allows for the combination of different materials to meet specific requirements.

[0026] This also offers the advantage of a base unit fixed to the household appliance with the smallest possible dimensions, matching the most cost-effective and material-efficient and largest overlap in the appliance portfolio. If required, the solution can be adapted to higher demands in a targeted, flexible, and resource-saving manner using the second additional part.

[0027] - 5 -

[0028] Requirements or innovative or future-oriented packaging concepts can be adapted and expanded.

[0029] The main part of the force transducer is preferably made of a plastic, making its manufacture very simple and cost-effective. The at least one additional part of the force transducer is preferably also made of a plastic, preferably polystyrene (PS), in particular expanded polystyrene (EPS), or a material with a honeycomb structure.

[0030] The force transducer is preferably designed with a large area in its force-absorbing surface. The term "large area" is understood, for example, to mean an area extending over a considerable dimension, particularly in relation to or in comparison with an area known from the prior art. The force-absorbing and large area of ​​the force transducer can be at least 25%, preferably at least 50%, and particularly at least 75% larger than the area of ​​a known force transducer from the prior art.

[0031] The three spatial axes (directional axes) with the variables x, y, and z are based, within the scope of this description, on a right-handed coordinate system with a mathematically positive direction of rotation. The spatial axis "x" (directional axis) is, by definition, the horizontal axis in the direction of the device width, the spatial axis "y" (directional axis) is, by definition, the horizontal axis in the direction of the device depth, and the spatial axis "z" (directional axis) is, by definition, the vertical axis in the direction of the device height.

[0032] According to one embodiment, the at least one additional part is preferably detachably connectable to the base part by means of at least one guide system, wherein the base part and the at least one additional part form a functional connection with which forces can be transmitted to the household appliance in both a horizontal and a vertical direction.

[0033] This allows the additional part to be joined to the base part in a simple and linear assembly step, while the base part can already be preferably detachably connected to the base part and thus fixed in place. The connection of the at least 202500187

[0034] - 6 -

[0035] The two components are joined by force-fit and / or form-fit connection and require no additional materials or fasteners such as screws, clips, cable ties, adhesives, or the like. Furthermore, the at least two components, due to their assembly, form a functional unit for force transmission, enabling the transfer of forces to the household appliance in both horizontal and vertical directions.

[0036] According to one embodiment, the guide system comprises several preferably flat guide surfaces which form a guide space in which the at least one additional part is at least partially inserted.

[0037] This guidance system allows, for example, a preferably linear joining of the at least one additional part in the z-direction ("vertical joining") or in the x-direction ("horizontal joining") and restricts the two further degrees of freedom x, z and y, z, respectively, to a large extent, preferably completely, by means of a positive and / or force-fit connection due to the at least partially enclosing guide surfaces. In the case of a preferably linear joining of the at least one additional part in the z-direction, the at least one additional part preferably rests freely on the treatment container due to the acting force of gravity, whereby no complete fixation of the z-degree of freedom occurs. In the case of a preferably linear joining of the at least one additional part in the x-direction, the at least one additional part preferably rests freely in the guide space, whereby no complete fixation of the x-degree of freedom occurs, and whereby a fixation of the x-degree of freedom may be necessary.In general, this guidance system involves fixing at least one additional part in five degrees of freedom and guiding it by means of the base body. Furthermore, at least one of the additional parts rests on the treatment container with at least one surface.

[0038] According to one embodiment, the guide system comprises at least one inner guide contour, which is formed, in particular incorporated, in the base part, and at least one outer guide contour, which is formed, in particular attached, in the at least one additional part, wherein the at least two preferably linear guide contours are congruent or approximately congruent.

[0039] - 7 -

[0040] This guide system facilitates a simple, reliable, and durable connection between the at least one additional part and the base part, while also allowing for easy detachment. The guide system can, for example, include a dovetail groove in the base part and a dovetail spline in the at least one additional part. Naturally, the guide system can also include other guide contours known to those skilled in the art.

[0041] According to one embodiment, the guide system comprises at least one outer guide contour, which is formed, in particular attached, in the base part, and at least one inner guide contour, which is formed, in particular introduced, in the at least one additional part, and the at least two preferably linear guide contours are congruent or approximately congruent.

[0042] This guide system also facilitates a simple, reliable, and durable connection between the at least one additional part and the base part, which can also be detached at any time. The guide system can, for example, include a dovetail joint in the base part and a dovetail groove in the at least one additional part, or a T-joint in the base part and a T-slot in the at least one additional part. Naturally, the guide system can also include other guide contours known to those skilled in the art.

[0043] According to one embodiment, the inner guide contour is a groove, in particular a dovetail groove, a T-slot or a groove with a polyphonic contour, and the outer guide contour is a spring, in particular a dovetail spring, a T-spring or a spring with a polygenic contour.

[0044] The guide system with these known contours facilitates a simple, reliable, and durable connection of at least one additional part to the base part, which can also be detached at any time. Naturally, the guide system can also include other guide contours known to those skilled in the art.

[0045] According to one embodiment, the two preferably linear guide contours are arranged at an angle of 0° to 90°, preferably 30° to 60°, and particularly 45°, to the horizontal.

[0046] - 8 -

[0047] Thus, the two preferably linear guide rails can be arranged between the horizontal and the vertical. Angles of 0°, 30°, 45°, 60° or 90° to the horizontal are particularly advantageous.

[0048] According to one embodiment, the base part can be attached to the supporting part.

[0049] This mounting location allows for easier assembly of the base unit to the household appliance and faster and more cost-effective packaging of the household appliance.

[0050] According to one embodiment, the base part is pushed onto the associated supporting part or crimped to it.

[0051] These mounting methods allow for easy installation of the force transducer's base onto the load-bearing part of the household appliance. They are also inexpensive to use and have proven effective in practice.

[0052] According to one embodiment, at least two force transducers are arranged on opposite sides, preferably longitudinal sides, in particular corners, of the household appliance.

[0053] This measure results in improved force transmission and absorption into the household appliance.

[0054] According to one embodiment, the household appliance has two side walls, in the upper areas of which, in particular at their upper corners, and in the lower areas of which, in particular at their lower edges, several force transducers are arranged.

[0055] This measure will result in further improved force transmission and absorption in the household appliance. 202500187

[0056] - 9 -

[0057] Since the clamps of commonly used clamp stackers do not reach the installation surface of the packaged household appliance, the distance between the lower force absorbers and the installation surface of the household appliance should be at least about one hundred millimeters.

[0058] According to one embodiment, the supporting part to which the base part can be attached is a frame of the household appliance, the treatment container and / or a side wall of the household appliance.

[0059] These listed components are characterized by high strength properties and thus guarantee a permanently functioning force absorption system.

[0060] According to one embodiment, it is provided that

[0061] - that the frame has horizontal crossbars running between opposing side walls of the treatment container, at the end areas of which a base part is arranged, or

[0062] - that the base part is arranged between the frame and / or the treatment container and an adjacent side wall of the household appliance, or - that the base part is arranged on a base tray of the household appliance, or - that the base part is arranged in an area of ​​a recessed base of the household appliance.

[0063] These designs generally result in a noticeably improved force transmission and absorption in the household appliance.

[0064] Advantageously, the force transducer, and in particular at least its base, is deformable on its side facing away from the associated supporting part and essentially rigid on its side facing the supporting part. This prevents sudden load changes during surface pressure loading and the risk of indentations on the side walls.

[0065] Advantageously, the force transducer, in particular at least the base part of the force transducer, has on the side facing the associated supporting part202500187

[0066] - 10 -

[0067] Stiffening ribs are added, thus enabling the simple manufacture of the essentially rigid side of the force-bearing part.

[0068] According to one embodiment, an upper force transducer has a contact surface, in particular a bearing surface, that is horizontal or approximately horizontal in the installed position and / or an upper force transducer has a contact surface, in particular a bearing surface, that is vertical or approximately vertical in the installed position.

[0069] This ensures effective absorption of stacking forces in packaged and stacked household appliances without a tabletop.

[0070] According to one embodiment, the household appliance is a dishwasher, in particular a household dishwasher, and the treatment container is a washing container for receiving items to be washed.

[0071] The household appliance can of course also be a washing machine, a tumble dryer, a household stove or the like.

[0072] Other possible implementations of the invention also include combinations of features or embodiments described previously or subsequently with regard to the exemplary embodiments, even if not explicitly mentioned. In such cases, the person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the invention.

A frame 15 is attached to the wash chamber 2, which serves on the one hand to increase the stability of the dishwasher 1 and on the other hand to attach side walls 16 of a machine housing enclosure (not described in detail). Force transducers 18 are arranged between the supporting parts 17 (sometimes shown with dashed lines) of the dishwasher 1 and a packaging 20 (not described in detail) that encloses the dishwasher 1 at least on one side. In Fig. 2, the supporting parts 17 are the frame 15 of the dishwasher 1 and the wash chamber 2 of the dishwasher 1.The frame 15 has horizontal crossbars 19 running between opposing side walls 16, of which, however, only the upper crossbar 19 is visible in Fig. 2. The dishwasher 1 also includes a base tray 21, which is arranged below the wash tub 2 and which houses various technical components and assemblies. A recessed plinth 22 is arranged behind a lower section of the tub door 3 and below the wash tub 2.

The positioning of the additional part 23.2Z in the installation position EL is achieved by gravity with free and contact contact on the rinsing container 2. Complete fixation in the vertical direction z (see Figures 4A and 4B) is not required.

[0119] The additional part 23.2Z can be joined to the base body 23.2G in a simple, linear assembly step, while the base body 23.2G is already installed and fixed on the dishwasher 1.

[0120] Figures 6 to 8 show three schematic perspective views of three further preferred embodiments of a force transducer 23.2 according to the invention.

[0121] The respective force transducer 23.2 is arranged on the left and rear upper corner EHL of the dishwasher 1 and comprises two components, one component being a base part 23.2G arranged on a supporting part 17 and the other component being a preferably flexibly deployable auxiliary part 23.2Z. The force transducer 23.2 can, of course, also have two or more auxiliary parts. The supporting part 17, on which the base part 23.2G is arranged, is shown in Figures 6 to 8 as a rear flange 25 formed on the wash tub 2 of the dishwasher 1. The base part 23.2G can be attached to the rear flange 25 in a known manner by sliding it on with positive and / or frictional engagement or by crimping. The base part 23.2G also rests against the wash tub 2202500187 at least on its underside.
