    BASKET FOR A DISHWASHER MACHINE, AND MACHINE
    DISHWASHER
    DESCRIPTION
    The invention refers to a basket for a dishwasher. The basket has multiple sensors configured to determine the load applied to the basket by the dishes arranged in the basket. In addition, the invention refers to a dishwasher.
    Document DE 198 23 806 A1 describes a dishwasher machine with a basket in which the dishes that must be washed by the dishwasher machine can be arranged. Sensors for determining the load of the basket can be arranged next to glutton rails for basket wheels or in different positions within the basket. As an example, a deformation meter can be applied to a plate that supports the glutton rail for a basket wheel.
    There are also dishwasher machines that allow the user of the dishwasher to choose a specific washing program for cases in which the basket is only half loaded. However, such a program must be selected manually and does not take into account the current situation regarding the loading of the basket.
    The present invention solves the technical problem of providing a basket and a dishwasher of the type mentioned at the beginning that make possible a better detection of the load applied to a basket of a dishwasher by the dishes arranged in the basket.
    This technical problem is solved by means of a basket and a dishwasher with the characteristics of the respective independent revindication. Advantageous configurations with other convenient developments of the invention are drawn from the dependent claims.
    The basket for a dishwasher according to the invention has multiple sensors configured to determine the load applied to the basket by the dishes arranged in the basket. Here, the sensors are formed as printed sensors. This is based on the discovery that the printed pressure sensors offer high flexibility for use in order to detect the load applied to a dishwasher basket by the dishes arranged in the basket. Printed pressure sensors can be controlled electronically with ease. In addition, the printed sensors can be applied at various points in the basket economically and, therefore, it becomes possible

    Precise detection of the load. Printed pressure sensors are also particularly useful in determining the distribution of the load within the basket. Therefore, by using the printed sensors, a better detection of the load applied to the basket is achieved by the dishes arranged in the basket.
    If the situation regarding the loading of the basket is known, the cleaning programs or washing programs of the dishwasher can be adapted to the specific situation related to the load and / or the position of the dishes inside the dishwasher. This helps to improve the performance of the dishwasher.
    The sensors may be attached to at least one rod element that is part of a bottom structure of the basket. Such configuration can be implemented particularly easily. Also, the quantity of sensors printed and their location and, therefore, the resolution with which the load can be detected, can be adapted to the elements provided inside the basket for the disposition of the dishes.
    In another advantageous configuration, the sensors are fixed to a grid attached to the bottom structure of the basket. This makes it possible for an existing basket to be adapted by joining the grid to the bottom structure. In addition, the communication lines to transfer the measurements captured by the sensors to a control unit of the dishwasher can easily be included in such a rack. Likewise, such a grid can be replaced if one of the printed sensors deteriorates. The grid also allows the positioning of the pressure sensors in appropriate places to detect the load applied by the dishes that are in contact with the grid elements of the grill while the dishes are arranged in the basket.
    It has also been shown that it is advantageous if the sensors are attached to a grid attached to the basket above the bottom structure of the basket. Here, at least one grid element of the grid can be brought into contact with an element of the bottom structure by the load applied to the basket by the dishes. At least one of the printed sensors is configured to detect such contact. In such a configuration, the grid is in a slightly elevated position with respect to the bottom structure of the basket. Thus, it can easily be ensured that at least one of the printed sensors will receive the weight of the dishes, since the grid element that supports the sensor comes into contact with the element of the bottom structure located below the grid. In such a configuration, a small amount of sensors in comparison is sufficient to detect the load applied by the dishes. Also different loads applied to the basket in different areas of the basket

    by the dishes and, therefore, the distribution of the load, can be determined easily with a small amount of printed sensors.
    In order to allow the movement of the grid elements of the grid relative to the bottom structure of the basket, it is advantageous if the grid is attached to the basket only at some points, for example, at four points. The grid can be attached to the basket, specifically, in four corners of the basket. Also, the grid material can have approximately the same stiffness as the elements that form the bottom structure of the basket. As an example, to make the bottom structure of the basket, steel elements with a plastic coating can be used. Similarly, the grid elements of the grid can be made of steel or a slightly less rigid material such as a fiber reinforced polymer.
    A good resolution and, therefore, an accurate detection of the load can be achieved, if the sensors are positioned in joints of the grid elements that form the grid. Similarly, the sensors can be positioned at joints of the bar elements of the bottom structure of the basket.
    However, in particular if the printed sensors are configured to detect the weight of the dishes that are in direct contact with the sensors, the resolution can be increased by placing the sensors at points located in the middle of such joints or in the joints and between of the unions.
    It is possible to achieve a particularly good resolution and, thus, a particularly precise detection of the load applied to the basket and also of the distribution of the load within the basket, if the sensors form at least one line. By way of example, the sensors may be printed along a line on at least a part of one of the bar elements or several of the bar elements of the background structure. Similarly, said line of printed sensors may extend along at least one of the grid elements that form the grid.
    Preferably, the basket has at least one signal transfer element to provide measurements captured by the printed sensors to a control unit of the dishwasher. By way of example, a signal transfer element formed as a connector provided next to the basket may be in contact with a corresponding connector provided within the dishwasher. Here, the connectors are preferably in contact with each other if the basket is fully inserted into the space

    of housing of the dishwasher machine, that is to say, in a position that allows to close a door of the dishwasher machine.
    The dishwasher according to the invention can have at least one basket according to the invention. Additionally or alternatively, the dishwasher can have at least one printed sensor that is arranged on a glutton rail for the basket of the dishwasher. The at least one printed sensor is configured to determine the load applied to the basket by the dishes arranged in the basket. Such a configuration, in which the printed sensors are arranged, for example, at points where the wheels of the basket rest on the glutton rails or gluttony shelves, do not need any modification or redesign of the existing baskets. However, the advantages of printed pressure sensors can be fully exploited.
    However, the dishwasher can also have the printed sensors arranged on the glutton rail and placed inside the basket or on the grid attached to the basket.
    Preferably, a control unit of the dishwasher is configured to adapt at least one parameter of a washing program or cleaning program depending on the load applied to the basket. As an example, the pressure applied to the wash water discharged from a spray arm of the dishwasher can be varied. An intermittent exit of the wash water from the spray arm can also be caused by the control unit depending on the location of the dishes inside the basket. Also, the duration of a cleaning cycle and / or the type of the washing program or cleaning program can be modified by the control unit depending on the load applied to the basket by the dishes.
    Alternatively or additionally, the control unit of the dishwasher can be configured to communicate to the user of the dishwasher at least one warning regarding the load applied to the basket. As an example, the warning could be issued to the user so that he redisposes or relocates the dishes or dishes inside the basket in order to achieve a more homogeneous distribution of the dishes inside the basket. Thus, the user can reposition the dishes before the start of the cleaning program. In addition, a warning may be issued to the user concerning the amount of detergent and / or rinsing medium to be used depending on the load of the basket and / or the distribution of the load within the basket.
    It is particularly simple and economical from the point of view of manufacturing that the printed sensors are applied by screen printing and / or printing by injection of

    ink. As such printed pressure sensors, for example, membranes with electrical resistance elements can be used.
    The advantages and preferred embodiments described with respect to the basket according to the invention are applicable correspondingly to the dishwashing machine according to the invention, and vice versa.
    The characteristics and combinations of characteristics mentioned above in the description, as well as the characteristics and combinations of characteristics mentioned below in the description of the figures and / or shown alone in the figures are usable not only in the combination indicated in each case, but also in other combinations or individually, without abandoning the scope of the invention. Therefore, it should be understood that those implementations that are not explicitly shown in the figures or explained, but that can be extracted through combinations of features separate from the exposed implementations are also understood and disclosed by the invention.
    Therefore, those forms of realization and combinations of features that do not have all the characteristics of an independent revindication originally written will also be considered as disclosed.
    Other advantages, characteristics and details of the invention can be drawn from the claims, the following description of the preferred embodiments, as well as based on the drawings, in which the elements with analog functions are accompanied by the same reference symbols. Here, they show:
    Fig. 1 in perspective view, a basket for a dishwasher, where a grid with printed pressure sensors is attached to the basket;
    Fig. 2 a view towards the bottom side of the basket shown in figure 1;
    Fig. 3 the grid with the pressure sensors printed on joints of grid elements of the grid; Y
    Fig. 4 a variant of the basket, where the grid with printed pressure sensors is slightly raised with respect to a bottom structure of the basket.
    Figure 1 shows a basket 1 for a domestic dishwasher. Various types of dishes such as plates, pots, and the like can be placed inside basket 1. Basket 1 comprises four side structures 2, 3, 4, 5 and a bottom structure 6.

    The lateral structures 2, 3, 4, 5 and the bottom structure 6 comprise in each case a number of bars 7, 8, 9 or elements of this type that form a mesh or grid. By way of example, the side structures 2, 3, 4, 5 comprise horizontal bars 7 and vertical bars 8, while the bars 9 of the bottom structures 6 form a mesh or grid at the bottom of the basket 1. Also, wings 10 or the like can be arranged next to the bars 9 of the bottom structure 6 to facilitate the placement of the dishes such as, for example, plates, in the basket 1. Up to here, the structural elements of the basket 1 are conventional, and different arrangements of the bars 7, 8, 9 and of the wings 10 or elements of this type may be present in variants of the basket 1.
    However, the basket 1 for the dishwasher has multiple pressure sensors 11 printed on a grid 12 attached to the bottom structure 6 of the basket 1 (see Figure 3). The grid elements 13, 14 forming the grid 12 may be positioned, for example, along the bars 9 of the bottom structure 6.
    In Figure 1, only two of the bars 9 forming the bottom structure 6 can be seen, since the grid 12 covers the other bars 9 of the bottom structure 6. The grid elements 13, 14 are preferably perpendicular to each other. yes, and the pressure sensors 11 may be placed in joints of the grid elements 13, 14 (see Figure 3). As shown in Figure 1, the grid elements 13, 14 may have the form of bars that extend in the direction of the length and in the direction of the width of the basket 1. By such arrangement of the sensors With pressure 11, a good resolution can be achieved to determine the load applied to the basket 1 by the dishes provided therein, as well as to easily detect the distribution of the load.
    Also, the pressure sensors 11 may be printed along the lines provided by the grid elements 13, 14 of the grid 12. In other words, the pressure sensors 11 may be placed alternatively or additionally in the sections located between the joints shown in Fig. 3. Such pressure sensors 11 printed along a line can in particular cover the entire grid 12.
    From Figure 2, it can be seen very well that the grid elements 13, 14 of the grid 12 extend along a large part of the bars 9 that form the bottom structure 6 of the basket 1.
    By placing the pressure sensors 11 on the grid 12 or network of this type, a very precise measurement of the load applied to different parts of the basket 1 can be achieved. This occurs mainly if the amount of pressure sensors 11 placed on

    grid 12 is raised. The resolution of the grid 12 can be increased, for example, by increasing the amount of grid elements 13, 14 with respect to the grid 12 shown in Figure 3 and placing the pressure sensors 11 in the joints of the grid elements 13 , 14. By way of example, the grid elements 13, 14 do not have to follow the bars 9 of the bottom structure 6, but the grid 12 can also extend through the free spaces existing between the bars 9 of the background structure 6.
    Another solution is explained with reference to Figure 4. Here, the basket 1 again comprises the side structures 2, 3, 4, 5 and the bottom structure 6 comprising a number of bars 9, for example, essentially orthogonal. However, the grid 12 is not attached to the bottom structure 6, but the grid 12 with the printed pressure sensors 11 is slightly raised with respect to the bottom structure 6. For this, the grid 12 is attached to the basket 1, for example, in four corners 15. In these corners 15, the side structures 2, 3, 4, 5 rest on each other.
    In particular, the grid 12 used in the variant of the basket 1 shown in Figure 4 can be made of a material that is as rigid as the material of the bottom structure 6. The bottom structure 6 can be made, for example, of 9 steel bars with a plastic protective coating. To form the grid 12, a slightly less rigid material such as a fiber reinforced polymer can also be used. If a similar dish or tableware is arranged inside the basket 1, the pressure sensors 11 placed on the lower side of the grid 12 come into contact with at least one of the bars 9 of the bottom structure 6. Such configuration allows utilization of a particularly small amount of pressure sensors 11, for example, only in some of the joints between the grid elements 13, 14. As long as the grid elements 13, 14 of the grid 12 can be brought into contact with an element of the bottom structure 6 and a pressure sensor 11 can detect such contact, the load applied to the basket 1 by the dishes can be determined immediately. Also the distribution of the load within the basket 1 can easily be determined by a grid 12 of this type placed on top of the bottom structure 6 of the basket 1.
    Likewise, the printed pressure sensors 11 may be arranged on glutton rails (not shown) provided within the dishwasher (not shown), which is configured to accommodate the basket 1. By way of example, the sensors of pressure 11 printed may be located in positions of the glutton rails,
    where wheels (not shown) of the basket 1 rest on the glues of the gluttony if the basket 1 is completely inserted into the housing space of the dishwasher.
    In Fig. 1, a signal transfer element 16 is shown schematically. This signal transfer element 16 transfers the measurements captured by the 5 pressure sensors 11 to a control unit (not shown) of the dishwasher. The control unit in turn determines the load applied to basket 1 and / or the distribution of the load. For this, the control unit can, for example, use interpolation functions. Then, the control unit adapts a washing program or cleaning program according to the load applied to the basket 1 and / or the distribution of the load within 10 of the basket 1. Thus, the performance of the Cleaning the dishwasher and / or reducing the duration of the cycle.
    Likewise, the dishwasher can issue a warning to the user of the dishwasher so that the dishwasher is placed inside the basket 1, if the dishes have not been placed homogeneously inside the basket 1. Also, the dishwasher 15 can advise the user to adjust the amount of detergent or rinse medium to be supplied for the wash cycle depending on the load applied to the basket 1 by the dishes.
