专利说明:
The invention refers to an external component of the domestic appliance with an outer surface, which is arranged on the visible side of the domestic appliance in the incorporated state of the external component of the domestic appliance. In the case of household appliances such as household appliances for the treatment of clothing, for example, washing machines, clothes dryers, or washer-dryers, of household appliances for preparing food, for example, cooking ovens, or household appliances for storing and preserving food, for example, refrigerators, freezers, or combined fridge-freezer devices, are known as components as an external component of household appliances that are positioned on the front side and, therefore, directed towards the user when the domestic appliance is installed as planned. These can be control panels or cladding parts. In this context, it is also known, for example, in the case of dishwashing machines, that such external components are made of plastic or stainless steel, or that they comprise a combination of metal and a plastic, in particular, a polymer material . As known plastics there can be mentioned here, for example, PP (polypropylene), or also ABS (acrylonitrile butadiene styrene). However, in the case of the known external components of the domestic appliance, the signs of wear such as scratches or indentations that occur in these known material compositions do not disappear. In this way, the overall optical impression of such an external component of the domestic appliance and, therefore, also of the entire domestic appliance is permanently impaired. The present invention solves the technical problem of creating an external component of domestic appliance and a corresponding domestic appliance, in which the signs of wear are reduced. This technical problem is solved by an external component of the domestic appliance and a domestic appliance according to the independent claims. An external household appliance component according to the invention has an outer surface, which is disposed on the visible side of a domestic appliance in the incorporated state of the external domestic appliance component. An essential idea of the invention is that the external component of the domestic appliance is made partially or completely of a shape memory material. Through such a design, it is possible that signs of wear that occur, such as scratches or crevices, can be corrected or compensated at least partially. Due to the properties of a shape memory material, it can be acted upon by thermal energy and / or electrical energy and, by means of this energy effect, the original shape of this external component of the domestic appliance can be restored again automatically. Therefore, also in the case of wear and tear that may be occurring, the external component of the domestic appliance is again repairable independently thanks to this specific design of the material, and these signs of wear can be compensated or eliminated. In this way, an external component of the domestic appliance has permanently high functionality, as well as a high quality optical appearance. In particular, it is provided that the shape memory material has at least one shape memory polymer. In the case of embodiments of the external component of the domestic appliance at least partially of plastic, the signs of wear that occur can then be easily corrected again. In particular, the shape memory material is provided to comprise a shape memory polyurethane. Additionally or alternatively, it can be provided that the shape memory material comprises a polycyclooctene crosslinked with dicumyl peroxide (DCP). In another embodiment, it can be provided additionally or alternatively that the shape memory material comprises a shape memory alloy. Also in the case of external components of metallic household appliances, the corresponding advantage is provided that the signs of wear that occur can be corrected. In particular, the shape memory alloy is expected to comprise nitinol. In another advantageous embodiment, it can be additionally or alternatively provided that the shape memory material comprises a polymer material irradiated with gamma rays. The shape memory material may also comprise, for example, ionomers, by way of example, a Na or Zn. Then, not only these materials also contribute to greater stability of the external component of the domestic appliance and increase the security against breakage. Other materials can also be added to the external component of the domestic appliance to fulfill other specific functionalities of the external component of the domestic appliance, for example, to individually adapt the robustness and / or the optical appearance. Here, too, surfaces that are generally harder and therefore also have a given protection against scratching can be created. Particularly advantageously, it is envisaged that the heat produced in a domestic appliance, which is generated during its operation, can be directed in the domestic appliance directly to specific positions of an external component of the domestic appliance. For this purpose, specific conduit ducts may be provided, for example, in the domestic appliance. Through these, thermal energy is directed specifically to the external component of the domestic appliance. In this way, an application of thermal energy is carried out on the external component of the domestic appliance in a practically independent and regular manner, so that a permanent continuous process is formed in order to be able to reduce the signs of wear that can occur independently and automatic again, or compensate them completely. In this embodiment, the domestic appliance is configured, so to speak, in a self-repairing manner, and the energy necessary in each case to act on the shape memory material is then generated by the domestic appliance itself. This is a particularly advantageous embodiment, since there is no need to add energy from the outside, nor do explicit repair cycles have to be carried out by an assembler. Advantageously, this can be done correspondingly with the addition of electrical energy to the external component of the domestic appliance. Also here, by way of example, the electrical energy of a power source of the domestic appliance or the electrical energy of electrical components of the domestic appliance can also be directed or specifically guided to the shape memory material of the external component of domestic appliance , so that, additionally or alternatively, a self-repair of the external component of the domestic appliance can take place. Preferably, the external component of the domestic appliance is a control panel or a front covering for a domestic appliance. Likewise, the invention refers to a domestic appliance with at least one external component of domestic appliance according to the invention or an advantageous embodiment thereof. In particular, the household appliance is a dishwashing machine, a device for treating clothes, a device for preparing food, or a domestic refrigerator device. Next, the embodiments of the invention are explained in more detail with reference to a schematic drawing. The only figure shows a domestic appliance 1, which can be configured as an example for the treatment of garments. However, the household appliance may also be, for example, a dishwasher. It can also be a household appliance for storing and preserving food, or a household appliance for preparing food. In the case of the embodiment as a domestic appliance 1 for the treatment of garments, it comprises a frame 2, in which a drum 3 is arranged, in which washing garments can be placed for cleaning. Also, the domestic appliance 1 comprises a door 4, which is configured to close the front side that opens the drum 3. The door 4 is pivotally arranged on the frame 2. Also, the domestic appliance 1 comprises a control panel 5, on which an actuating device 6 is formed. The control panel 5 represents an external component of the domestic appliance. In addition, it can be provided that there is a front lining 7, which also represents an external component of the domestic appliance. The control panel 5 and the front cover 7 are components of the front side, which are directed towards the user on the front side in the case of proper and intended use, or when the domestic appliance 1 is installed correspondingly. The control panel 5 is made partially or completely of a shape memory material. The shape memory material comprises at least one shape memory polymer. The shape memory material may comprise a shape memory polyurethane. Additionally or alternatively, it can also comprise a cross-linked polycyclooctene, in particular, with dicumyl peroxide (DCP). If the control panel 5 is made entirely of plastic on these corresponding outer surfaces, this design of the shape memory material, as set forth in the previous examples, is possible. Here, the most varied variants can also be provided with respect to this shape memory material. It can also be provided that the external component of the domestic appliance in the form of a control panel 5, in particular on its outer surface, is made partially or entirely of metal. In the case of such a design, the shape memory material may also additionally or alternatively comprise a shape memory alloy, for example, nitinol. In the case of another alternative embodiment, the shape memory material may also additionally or alternatively comprise a polymer material irradiated with gamma rays. Thus, with respect to its material composition, the control panel 5 can present the most varied designs, although in each case it comprises at least partially a shape memory material. The same applies in a manner analogous to the front lining 7, which can also be made of a shape memory material and can be configured in accordance with the specific embodiments, as they have been exposed in relation to the panel of control 5. The domestic appliance has a component 8 that emits thermal energy during operation, which can preferably be directed by a steering device specifically to the control panel 5 and / or to the front cover 7, so that the thermal energy acts here on The shape memory material. Additionally or alternatively, at least one electronic component 9 that generates electric power is provided, which can be directed by a steering device that is preferably present to the control panel 5 and / or to the front cover 7, so that the energy Electric acts here on the shape memory material. Also in the case of the other types of household appliances mentioned at the beginning, such external components of domestic appliance are provided arranged on the visible side and the front side, which are then made correspondingly of a shape memory material, or also, as may be the case with the embodiment of the figure shown, they can be made entirely of a shape memory material.
