    DOMESTIC DEVICE WITH A TITANIUM DIOXIDE FILTER
    DESCRIPTION
    The invention refers to a domestic appliance, which comprises a frame in which a housing space is designed in which objects can be introduced to be processed by the domestic appliance.
    There are domestic appliances configured for the treatment of garments, for example, washing machines, washer-dryers, or dryers. Also, domestic appliances for storing and preserving food are known, for example, refrigeration devices, freezers, or fridge-freezers, as well as household appliances for washing dishes, that is, dishwashing machines.
    In these specific domestic appliances, it is known that garments, food or tableware used can be introduced into a housing space to be processed accordingly. In this context, it is also known that unpleasant odors can occur in the accommodation space caused by used clothing, food residues that remain on the dishes, or by certain foods, which are generally undesirable. Likewise, such unwanted odors from the accommodation space can occur as a result of the objects introduced, in the first place, or be intensified by these if, due to humidity and / or relatively high temperatures, it can happen that the microorganisms are modified or they disintegrate and, coupled with this, such unpleasant odors can occur. In addition, also as a consequence of food waste, oxidation processes can be initiated that can also lead to the corresponding molecules spreading unpleasant odors.
    In addition to these unpleasant odors, other side effects caused by these may consist of the user perceiving a negative sensation regarding hygiene. In addition, in the case of garments, an accumulation or mixture of such unpleasant odors can also occur, which even increases the negative sensation perceived by the user in relation to hygiene.
    It is known that, to reduce such unpleasant odors in these domestic appliances, chemical products intended to cover such odors are used. However, the use of chemical products entails other inconveniences, and the reduction or avoidance of such unpleasant odors is only possible in a limited way.

    The present invention solves the technical problem of providing a domestic appliance by means of which the unpleasant odors that occur therein can be reduced at least to a greater extent.
    Said technical problem is solved by a domestic appliance with the characteristics of revindication 1.
    A domestic apparatus according to the invention comprises a frame in which a housing space has been designed. This accommodation space is configured and arranged in such a way that they can be introduced into the objects to be processed by the domestic appliance. An essential idea of the invention is that the domestic apparatus comprises a unit for the compensation of odors as an object component, which is intended for the compensation of unpleasant odors that occur in the housing space, and coupled to the accommodation space . The unit for the compensation of odors comprises a photocatatic material as a material for the compensation of odors. Thanks to this design of the domestic appliance, unpleasant odors can be at least clearly reduced in a simple and comprehensive way. By providing an object and separate unit, the compensation of odors can be carried out more precisely. In addition, additional chemical products are no longer needed to achieve such odor compensation. Thanks to the use of a photocatalyst as a material for odor compensation, odor compensation is greatly facilitated and, in this way, it is possible to clearly reduce the most varied and persistent odors.
    Preferably, it is envisioned that the odor compensation unit comprises titanium dioxide as a material for odor compensation.
    In particular, the odor compensation unit comprises a titanium dioxide filter. This configuration is particularly advantageous, since a wide odor compensation is carried out through said filter, since these odor generating molecules can be filtered easily and completely. Likewise, the filter is a component that can be easily replaced, so that during the useful life of the domestic appliance, said filter can be replaced several times. Thus, by means of the titanium dioxide compensation material, a particularly notable odor compensation is constantly facilitated.
    Preferably, the titanium dioxide filter is arranged such that it is at least in a stream of air flowing through the housing space, in particular,

    I went through it. In this way, a particularly exhaustive and therefore effective exfiltration of the molecules that produce unwanted odors can be carried out.
    Preferably, it is envisioned that the titanium dioxide filter itself is disposed within the housing space, whereby odor compensation can take place very exhaustively. Therefore, it is not necessary to connect fluids through flow conduits between the housing space and a filter that is disposed outside the housing space.
    However, it can also be provided that the titanium dioxide filter is disposed outside the housing space. In this way, the construction space of the accommodation space is not restricted.
    Preferably, it is envisioned that the odor compensation unit can be activated in a user-defined manner. Thus, the olfactory sensations of the user can be taken into account individually, who can respond to the present situation regarding odors.
    Preferably, it is envisioned that the odor compensation unit is controlled by a control unit and activated at fixed time intervals and / or that can be activated during fixed time intervals.
    Preferably, it is envisioned that the odor compensation unit comprises an odor detection sensor with which the concentration of at least one odor generating medium can be captured, where, preferably depending on whether a concentration threshold is exceeded In this way, the odor compensation unit can be activated, in particular, automatically activated. Through this realization, you can react very quickly and immediately to unwanted odors that are already being produced.
    The domestic appliance may preferably be a dishwasher, a refrigerator and / or freezer, or a laundry treatment apparatus.
    Next, the embodiments of the invention are explained in more detail with reference to the schematic drawing. The only figure shows in a simplified representation in perspective a domestic appliance 1, which can be configured for the treatment of garments and be, for example, a washing machine, a washer-dryer, or a tumble dryer. However, the domestic appliance 1 can be

    10

    also a dishwasher or a refrigeration device, a freezer, or a fridge-freezer for storing and preserving food.
    The domestic apparatus 1 comprises a frame 2, in which a housing space 3 delimited by the walls of an internally positioned container is arranged. As an example in a domestic apparatus for the treatment of garments, this accommodation space 3 can be a drum into which the garments can be introduced. In a dishwashing machine, it can be the space in which the dishes are introduced to be washed and, in a domestic appliance for storing and preserving food, it can be a refrigeration or freezing space.
    The domestic apparatus 1 comprises a unit for the compensation of odors 4, which is configured for the compensation of the unpleasant odors that occur in the housing space 3. For this purpose, the unit for the compensation of odors 4 is coupled, specifically, in fluid connection, with the accommodation space 3.
    In this embodiment, it is envisioned that the odor compensation unit 4 comprises at least one titanium dioxide filter 5, which may be disposed outside the housing space 3 and in fluid connection therewith, as It is represented in the figure. However, it can also be arranged within the accommodation space 3.
    In particular, it is envisioned that a stream of air 6 is generated that flows between the housing space 3 and the titanium dioxide filter 5, so that the unpleasant odors 7 with the molecules that generate them are carried along with the air stream 6 and pass through the titanium dioxide filter 5. Then, the titanium dioxide filter 5 filters these molecules, so that unpleasant odors are eliminated.
    Preferably, the domestic apparatus 1 comprises a control unit 8, by which the compensation of odors can be controlled. In this context, said compensation can be carried out at fixed time intervals and, thus, can be initiated at specific successive moments of this process for the compensation of odors. Additionally or alternatively, the active odor compensation process can also be activated during fixed predetermined periods of time or during fixed time intervals.
    Also, the domestic appliance 1 comprises at least one odor detection sensor 9,
    by which you can capture the concentration of at least one molecule that generates a
    unpleasant smell. Said information collected is then transferred to the control unit
    5

    8, where it is analyzed as to whether there is a specific threshold value of concentration that exceeds a threshold value of odor and, therefore, if the process for odor compensation is to be initiated. In this context, it can also be provided that there is a fan not shown, which is controlled by the control unit 8, and that generates the air flow 6.
    The titanium dioxide filter 5 works based on a photocatatic effect. Photocatalysis is a reaction that uses light to activate substances that modify the speed of a chemical process, without this substance contributing to this chemical reaction or constituting part of it. Titanium dioxide is a semiconductor that has a banned energy band of 3.2 eV. If the titanium dioxide is irradiated by photons with an energy greater than 3.2 eV, the titanium dioxide material is excited.
    The atmospheric oxygen then acts as an electron collector. On the other hand, hydrogen atoms can react in a single electron oxidation with water to generate a highly reactive hydroxyl radical. The hydrogen ion and the hydroxyl radical are very powerful oxidants that are used to oxidize organic contamination. In this way, organic media, such as smoke and unpleasant odors, are eliminated or compensated, and carbon dioxide and water are generated.
    Specifically in a dishwasher, it can be provided that the titanium dioxide filter 5 is arranged in a zeolite container.
    The smell detection sensor 9 can be an optical sensor, a piezoelectric sensor, or a catallotic sensor. However, the sensors mentioned by way of example should not be construed as limiting. The specific smell detection sensor 9 can also be individually designed or arranged in such a way that it is adjusted to the odors that are generated in increasing in respective types of domestic appliances and that, preferably, also detects the main causes that cause such unpleasant odors in each case.
