    image 1 DOMESTIC APPARATUS FOR THE TREATMENT OF CLOTHING CLOTHES WITH A DETERGENT TRAY WITH SPECIFIC COATING DESCRIPTION
    The invention refers to a household appliance for the treatment of garments, which includes a frame and a detergent tray disposed in the frame for the agents for the treatment of clothing.
    In a washing machine or washer-dryer, it is known that the agent for treating clothes, for example, a liquid or powder detergent, is introduced into the so-called detergent bucket and is then transported from there to the drum, in which clothes are placed for washing, for example, by adding water.
    During the operation of a washing machine or clothes dryer, condensed water is produced, which can also be formed in the area of the detergent drawer. This happens in particular when the treatment of the laundry is carried out at 15 relatively high temperatures and, for example, an operating program is applied to wash washable clothes at very high temperatures, such as bedding, for example. in which case the condensed water also accumulates therefore on the bottom of the detergent drawer. If a user then opens the detergent drawer by removing it as a drawer, the drops of water adhered to the bottom of the bucket
    20 detergent will drip down. In this way, these drops of water wet or soak, for example, the floor or other elements located under the detergent dispenser.
    The present invention solves the technical problem of providing a household appliance for the treatment of garments in which the dripping of water droplets is significantly or completely reduced when the detergent tray is removed.
    Said technical problem is solved by a domestic appliance according to independent claim 1.
    A household apparatus according to the invention for the treatment of garments includes a frame and a detergent tray arranged in the frame to house the agents for treating clothes. An essential idea of the invention is that the detergent tray is coated at least on a bottom with a protective layer that prevents the
    image2
    formation of water droplets that adhere to the bottom. By means of this additional protective layer formed on an outer bottom of this detergent cuvette, permanent or long-term adhesion of water droplets is considerably or completely reduced. Therefore, by means of this configuration it is achieved that, although the condensed water that is produced during the operation of the domestic appliance can still be formed on the bottom, the drops form very quickly and fall from the bottom immediately and, therefore, also very quickly or that, on the other hand, the formation of drops is prevented and only a larger or large film of water can be formed on the bottom, with which dripping is prevented, in particular, when the detergent cup is find in open state.
    Therefore, this configuration at least reduces the likelihood that the condensed water produced during the operation of the household appliance is also deposited as drops on the bottom of the detergent drawer for an extended period of time. On the contrary, the condensed water can be deposited, but it drips immediately or only remains there by means of a thin film that remains attached in the long term. When the detergent cup is opened, which usually only happens later or after the end of the treatment process, the adhesion of large drops of water on the bottom, which could then drip down on the floor when the detergent cup is in the open state , is reduced considerably or completely.
    Preferably, it is envisioned that the protective layer has at least hydrophobic components. Hydrophobic components prevent the formation of large drops of water that would remain attached to the bottom for a long time. On the contrary, such drops of water form very quickly and also drip from the bottom very quickly. Thus, such drops of water drip from the bottom when the detergent drawer remains closed, or when the detergent drawer is not normally open in any case during the operation of the household appliance. In this context, super hydrophobic components can be formed in particular, whereby the achievement of the aforementioned advantages is promoted.
    It can also be provided that the protective layer has at least hydrophilic components. By this configuration, the formation of water droplets can be practically completely avoided, and then only a thin film of large water that does not drip can form on the bottom.
    In a particularly advantageous embodiment, it is provided that the protective layer has amphipathic components. By such components, a combination of hydrophobic and hydrophilic components is formed to some extent. In this way, the aforementioned configurations are promoted again since, even if a lot of condensed water has formed and then drops may form, they form again very quickly, falling from the bottom and, on the other hand, on the background is quickly generated a thin film of water of great extent.
    image3
    Preferably, it is envisioned that the protective layer has one or more silane derivatives as a component. Preferably, the protective layer includes TEOS (tetraethylorthosilicate) and / or HMDS (hexamethyldisilazane) and / or HMDSO (hexamethyldisiloxane) as a silane derivative. These components may also be the amphipathic components.
    Additionally or alternatively, it can also be provided that the protective layer has titanium dioxide derivatives as a component.
    Similarly, additionally or alternatively, it may be provided that the protective layer has silicon dioxide and / or aluminum oxide as a component. Nanoparticles or precursors can also be provided for this.
    In an advantageous embodiment, the components are expected to be contained or embedded in a matrix material. In this way, the components are distributed very evenly and contained in an appropriate support material that can be fixed to
    or integrated into the material of the detergent drawer in a sufficiently safe manner. Thus, the existing environmental conditions in the area of a detergent cuvette of the domestic appliance are also taken into account for an extended period of time, and this protective layer is fixed to, in particular, integrated in, the detergent cuvette, functionally and stably in the long term.
    Preferably, the matrix material is expected to be a thermoplastic material. As a matrix material, in particular, by way of example, a thermoplastic extrusion moldable plastic, preferably coextrusion moldable, can be provided.
    It can also be provided that the matrix material is a varnish or a resin. Similarly, as a matrix material a paint can be provided.
    The protective layer can be generated by coextrusion. Similarly, it can be provided that the protective layer is produced by thermally assisted gas phase chemical deposition (TECVD), by vacuum plasma, inkjet methods, screen printing, or by sol-gel synthesis. Additionally, so-called immersion coating or rotation coating can also be carried out and, similarly, the generation of the protective layer can be carried out by spraying or brush application.

    It may also be provided that not only the bottom of the detergent tray is correspondingly coated, but that the entire detergent tray is provided with a corresponding protective layer.
    Other features of the invention are drawn from the claims, the figures and the description of the figures. The features and combinations of features mentioned above in the description, as well as the features and combinations of features mentioned below in the description of the figures and / or shown in the figures can be used, not only in the specific combination in each case, but also in other combinations or separately without leaving the scope of the invention. Thus, it will also be considered that those embodiments not exposed or explicitly shown in the figures, but which can be extracted by combinations of separate features from the exposed configurations, are understood and set forth in the invention.
    Next, the embodiments of the invention are set forth in more detail based on the schematic drawings. They show:
    Fig. 1 a perspective representation of an embodiment of a household appliance according to the invention for the treatment of garments;
    Fig 2 an enlarged perspective view of a section of the household appliance according to figure 1 with a detergent tray removed;
    Fig. 3 a simplified representation of a partial area of the detergent tray with the bottom; Y
    Fig. 4 a representation according to figure 3, in which an alternative configuration is illustrated.
    In the figures, identical or equal function elements are accompanied by the same reference symbols.
    In figure 1, a household appliance 1 for the treatment of garments is shown, which can be, for example, a washing machine or a washer-dryer. The domestic appliance 1 includes a frame 2 in which a drum 3 for accommodating clothes to be washed is arranged being rotatably supported. Likewise, a container for the washing foam not shown is also arranged, inside which the drum 3 partially extends, and in which the washing foam is contained. On the front side, the drum 3 has a loading opening that is locked by a door 4. The domestic appliance 1 also includes a detergent bucket 5 which can be accessed frontally, and which is formed as a drawer and therefore, it can be extracted from or introduced to the frame 2 in a horizontal direction. In the detergent bucket 5 an agent for the treatment of clothes is introduced, which is then directed or propelled to the container for the washing foam and to the drum 3 adding water, which can be supplied, for example, through a External water supply system.
    image5
    In Fig. 2, the domestic appliance 1 is shown in perspective partial representation in the area of the detergent drawer 5, which is shown here in the extracted and, therefore, open state. The detergent bucket 5 has a front part 6, which includes a grip area 7 that a user can grasp by hand and thus remove the detergent bucket 5. As can be seen, the detergent bucket 5 includes an area of housing 8, adjacent to the front part 6, in which several chambers 9, 10 and 11 are formed in this embodiment as a groove. The clothing treating agent can be introduced into one or more of these chambers 9 to 11. The detergent bucket 5, specifically, the area 8, includes a bottom 12 which also has an outer side directed downwards. If the detergent bucket 5 is inserted and the household appliance 1 is in operation, for example, clothes are being washed at a very high temperature, condensed water can then be formed in the frame 2, which can be accumulated or deposited on the bottom 12.
    It is envisaged that the detergent bucket 5 is formed with a protective layer at least on its bottom 12. In relation to the above, a simplified representation of section through the detergent bucket 5 is shown in Figure 3. It can be seen that a protective layer 13 is formed on the bottom 12, which includes at least hydrophilic components in the embodiment shown, whereby the formation of water droplets that could be formed from the condensed water deposited is avoided, forming only one film 14 flat and relatively large, which does not drip, even if the detergent bucket 5 is open.
    In figure 4, a representation of the detergent bowl 5 is shown in section representation corresponding to figure 3, in which a protective layer 15 is also formed on the bottom 12, which includes at least hydrophobic components by means of which there is a formation of drops 16 very fast and intense, so that the


    drops form immediately and very quickly after the condensed water is deposited on the bottom 12 or on the protective layer 15, and drips immediately. These drops 16 then fall into the frame 2 during operation of the domestic appliance, since the detergent bucket 5 is usually closed while the domestic appliance 5 is in operation. By this embodiment, the amount of drops 16 on the bottom 12 is considerably reduced, and the drops 16 that in any case form then drip very quickly from the bottom 12 or the protective layer
    fifteen.
    In a preferred embodiment, it can also be provided that the protective layer has
    10 both hydrophobic and hydrophilic components, it being possible in particular for the protective layer to have amphipathic components by means of which the functionality of the protective layer 13 is combined, as set forth in relation to Figure 3, and the functionality of the layer protective 15, as stated in relation to figure 4.
