Definitions
- the present invention relates to a system with a dishwasher, a method for operating a dishwasher and a computer program product.
- Known dishwashers are set up to carry out a washing program in an optimized manner on the basis of a load in the dishwasher.
- a washing liquor temperature, a pump speed and/or a cleaning agent are adjusted depending on the type of washware.
- the load in the dishwasher can be determined by means of image recognition based on an image of items to be washed.
- the camera is to be triggered in a suitable manner and an image suitable for image recognition is to be stored.
- WO 2018/044094 A1 discloses a dishwasher with a camera that is set up to record an image of a washware receptacle.
- the washware holder has a marking, by means of which a position of the washware holder is determined on the basis of the image. Furthermore, items to be washed that are visible in the recorded image are recognized.
- an object of the present invention is to improve the operation of a dishwasher.
- a system with a dishwasher in particular a household dishwasher, is proposed.
- the system comprises a control device for carrying out a washing program depending on a load of items to be washed on a wash item holder of the dishwasher, and a camera for capturing an image of at least a partial area of the wash item holder depending on an extension position of the wash item holder, the control device being set up to display the captured image in To store dependence of the extract position when capturing the image on one of the extract position associated memory space of a number of memory locations. Each memory space of number is a set of out- assigned to train positions.
- the system also includes an image analysis unit for determining the load in the washware holder as a function of the images stored in the memory locations.
- This system has the advantage that different storage locations are provided for images on which different partial areas of the washware receptacle are visible. This reduces the amount of memory required, since each memory location in particular only stores a single image. The stored image is in particular the most recent image that shows the respective sub-area. Another advantage is that a number of images that need to be analyzed to determine the loading can be reduced. In particular, it is sufficient to analyze only the most up-to-date image on which the sub-area can be seen for a respective sub-area. A required computing power and/or computing time can thus be reduced.
- the control device can be implemented in terms of hardware and/or software.
- the control device can be designed, for example, as a computer or as a microprocessor.
- the control device can be embodied as a computer program product, as a function, as a routine, as part of a program code or as an executable object.
- the control device is set up to carry out the washing program depending on the load. This means that the control device adapts or changes a sequence of the wash program and/or individual parameter values of a partially specified wash program.
- the sequence includes in particular a sequence of partial program steps, such as a pre-wash, a main wash, a final rinse and drying Setting a water switch, setting a water hardness and the like. For example, if the load largely comprises glassware, a water hardness can be set higher and a circulation pump speed reduced compared to a load that mainly comprises ceramic ware and/or metal ware.
- the dishwasher comprises, for example, a washing chamber in which at least one washware receptacle that is mounted in an extendable manner is arranged. When the door of the dishwasher is open, the items to be washed can be pulled out, thus enabling easy loading of items to be washed into the items to be washed.
- the dishwasher has a camera on the upper edge of the washing compartment, for example, which is set up to capture an area determined by the radius of movement of the washware holder.
- the camera includes a wide-angle lens and is set up to capture a large solid angle.
- the camera is set up to capture the entire washware receptacle when it is in a fully pulled-out state, ie in a maximum pulled-out position.
- the camera is activated by opening the door and outputs an image stream to the control device.
- the image stream includes sequentially recorded images, with a specific image acquisition rate being specified.
- the images are transmitted unprocessed in the form of raw data from the camera to the control device.
- the control device takes over the further processing, for example the decision as to whether an image is to be saved or discarded.
- the camera can therefore have a comparatively simple structure and requires only a small amount of resources. The camera can thus be particularly cost-effective.
- the camera can be set up to capture an image in an infrared spectral range, a visual spectral range and/or in an ultraviolet spectral range.
- the camera may perform the processing of the captured images.
- the dishwasher comprises a plurality of washware receptacles, which are arranged in particular vertically one above the other in the dishwasher. If the dishwasher has several items to be washed, the above and following features and/or explanations apply individually to each item to be washed, where applicable.
- the image captured by the camera shows a partial area of the washware receptacle.
- the portion that is visible on the image depends on the current draw position of the Items to be washed and the field of view of the camera.
- the field of view of the camera is defined in such a way that when the washware holder is completely pushed in, only a front edge of the washware holder, for example a handle on the washware holder, is visible in the image. If the washware holder is now pulled out, a larger partial area of the washware holder gradually enters the field of view of the camera. For example, if the wash rack is pulled out halfway, about half of the wash rack is visible in the image.
- the image is stored by the control device in an assigned memory location.
- the current pull-out position of the washware holder is used as an indicator for the visible sub-area.
- the number of storage locations is preferably limited; in particular, fewer than ten storage locations are provided for each item to be washed, preferably fewer than five storage locations. The memory requirement for storing the images can thus be significantly reduced.
- each captured image is stored together with a time stamp that contains a point in time when the image was captured.
- the image analysis unit is set up to determine the load of the respective washware receptacle on the basis of the recorded images.
- the image analysis unit can use methods of signal analysis, pattern recognition, image recognition, image classification and the like, for example.
- the image analysis unit can carry out the determination at least partially on the basis of artificial intelligence, such as a trained neural network.
- the image analysis unit preferably only analyzes the most recent images of a respective sub-area. For example, a more up-to-date image can be available for a front partial area of the wash item holder than an image that shows the entire wash item holder. This is the case in particular when the user of the dishwasher has only partially pulled out the washing items holder to load the front area thereof. In this case, the image analysis unit will, for example, analyze the image that shows the entire item to be washed and the more up-to-date image that shows the front partial area. On the other hand, other images that show, for example, larger or also smaller sub-areas than the front sub-area and that are older are preferably not used analyzed because they contain outdated and/or redundant information.
- the load in the front partial area is determined on the basis of the more up-to-date image, and the load in the remaining part of the wash item holder is determined on the basis of the image of the entire wash item holder.
- the current load is thus determined for each sub-area, with the required computing power and/or computing time being reduced.
- the load is preferably determined only when the user of the dishwasher starts the washing program. Since in each washing program washing liquid must first be fed into the washing chamber, there is enough time for this without the execution of the washing program being delayed.
- control device is set up to capture an image position of a feature of the washware holder in the captured image and to determine the pull-out position of the washware holder depending on the captured image position of the feature of the washware holder.
- This embodiment has the advantage that the current pull-out position of the washware receptacle is automatically recognized by the control device on the basis of the captured images, without an additional device being required.
- Different items to be washed have, for example, different features or different positions of the features.
- a feature is in particular a specific pattern or structure.
- the feature can only be visible in a specific spectral range, for example only in the infrared spectral range.
- control device is set up to detect the image position of the feature of the washware reception depending on an area of interest of the image.
- the feature of the washware holder comprises a handle of the washware holder for manually removing the washware holder from and for manually pushing the washware holder into the dishwasher and/or a marking arranged on the handle.
- control device is set up to store the respectively most current image of the washware receptacle at a specific pull-out position in the memory space assigned to the specific pull-out position.
- the most recent image is the image with the most recent recording time. If the control device processes the image stream of the camera sequentially, the image just processed will always be the most up-to-date, which is why the control device stores this in the assigned memory location and thus overwrites an image already stored there. If the processing is not sequential and there may be time shifts, it can be provided that the control device compares the time stamp of the candidate image and the image already stored before storing a candidate image in an assigned memory location and stores the more recent of the two.
- each storage location is assigned a specific interval from the set of possible pull-out positions for the items to be washed.
- the specific interval corresponds to the partial area of the respective washware receptacle that is visible on the recorded image. For example, in a pull-out position that is between 90%-100% in relation to the maximum pull-out position, a partial area comprising 90%-100% of the washware receptacle is visible on a captured image.
- an interval is understood to mean, in particular, a coherent range of values. All specific intervals together can, but do not have to be all possible Include statement position. Images captured at uncovered separation positions are accordingly discarded and not saved.
- At least two storage locations are provided, with a first interval assigned to a first storage location comprising a maximum pull-out position of the washware holder and having a first width, a second interval assigned to a second storage location adjoining the first interval and having a second width, wherein the first width is narrower than the second width.
- the first width is preferably comparatively narrow, for example encompassing only 5%-10% of the entire pull-out area.
- This embodiment has the advantage that an image showing the entire washware receptacle (maximum pull-out position) is not replaced or overwritten by an image on which the washware receptacle is only partially visible. In most cases, this advantageously provides an image of the entire washware receptacle. By choosing a wider second interval, the number of memory locations required can be effectively reduced while at the same time covering the extraction area as much as possible.
- the camera is set up to capture an image stream of the washware receptacle, two consecutive images in the image stream having a predetermined time interval
- the control device being set up to detect a movement of the washware receptacle as a function of two successive images of the image stream to determine and to store one of the two consecutive images as a function of a determined movement
- a camera that includes a mechanical shutter or a complex electronic shutter can advantageously be dispensed with. Images that are blurred due to a movement of the washware receptacle and are therefore unsuitable for an image analysis are recognized by the control device and can therefore be discarded.
- the control device determines the movement in particular on the basis of a change in the image position of the feature of the item being washed. Determining the loading is therefore more robust.
- the movement can be determined from a change in the image position of the feature in both the X-direction and the Y-direction. For example, the image position is determined on the basis of a centroid of an areal feature. If the feature is partially obscured, then the centroid has a different image position.
- the image analysis unit is set up to determine the load as a function of a recording time assigned to a respective stored image and the pull-out positions assigned to the memory location, with a first image in which a specific partial area of the washware holder is visible and the recording time of which is younger than the The recording time of a second image, in which the specific partial area of the washware holder is also visible, is used to determine the load for the specific partial area of the washware holder.
- control device is set up to delete an image whose recording time is older than a predetermined threshold value.
- the threshold value can be several days, for example. With this embodiment, it can be achieved, for example, that images that were recorded before a first wash program was carried out are not used to determine the load for a second wash program.
- the control device is set up to put the camera into an idle mode after a predetermined time interval has elapsed, in which the status of the items being washed is constant.
- the predetermined time interval includes, for example, between 5 minutes and 20 minutes.
- the image analysis unit is arranged in a device external to the dishwasher, with the control device and the image analysis unit being set up for the mutual transmission of data.
- the dishwasher can have a less complex structure.
- the image analysis unit can have a particularly high computing power if it is integrated, for example, in a server accessible via the Internet or the like.
- utilization of the image analysis unit can be increased by using it from a plurality of dishwashers. Updating the image analysis unit is also possible in a simplified manner in this embodiment.
- the control device and the image analysis unit can transmit data, for example, via the Internet and/or via a mobile phone connection, such as 3G, 4G or 5G.
- the control device transmits stored images, in which case it only transmits the most recent ones, as explained above.
- the image analysis unit receives the images, carries out the analysis and transmits the load determined to the control device.
- the image analysis unit is set up to determine a type, a quantity, an orientation, an arrangement and/or a material of the items to be washed arranged in the items to be washed.
- a method for operating a dishwasher in particular a domestic dishwasher, is proposed.
- a first step an image of at least a partial area of a wash item holder of the dishwasher is captured as a function of an extension position of the wash item holder.
- the pull-out position of the washware receptacle at the time the image is captured is determined.
- the image is stored in a storage location of a number of storage locations assigned to the extract position, with each storage location of the number being assigned a set of extract positions.
- a load of the washware receptacle is determined as a function of the images stored in the memory locations.
- a rinsing program is carried out depending on the load determined.
- a computer program product which comprises instructions which, when the program is executed by a computer, cause the latter to execute the method described above.
- a computer program product such as a computer program means
- a server in a network, for example, as a storage medium such as a memory card, USB stick, CD-ROM, DVD, or in the form of a downloadable file. This can be done, for example, in a wireless communication network by transferring a corresponding file with the computer program product or the computer program means.

- four memory locations are provided for storing four images IMG for a respective washware receptacle 12 to 14 .
- An interval Z1-Z4 is assigned to each memory location, for example as explained with reference to FIGS. In further embodiments, more memory locations can be provided.
- an image IMG is not stored in any of the memory locations.
- a first image IMG1 is captured at a point in time t1.
- the controller 15 determines that the image position of the handle 12A in the captured image IMG1 is in the interval Z3, and therefore the image IMG1 is stored in the memory space associated with the interval Z3.
- a second image IMG2 is captured at a point in time t2.
- the controller 15 determines that the image position of the handle 12A in the captured image IMG2 is in the interval Z1, and therefore the image IMG2 is stored in the memory space allocated to the interval Z1.
- a third image IMG3 is captured.
- the controller 15 determines that the image position of the handle 12A in the captured image IMG3 is in the interval Z3, therefore the image IMG3 is stored in the memory space allocated to the interval Z3.
- the previously saved image IMG1 is overwritten.
- a fourth image IMG4 is captured at a point in time t4.
- the controller 15 determines that the image position of the handle 12A in the captured image IMG4 is in the interval Z1, therefore the image IMG4 is stored in the memory space allocated to the interval Z1.
- the previously saved image IMG2 is overwritten.
- a fifth image IMG5 is captured at a point in time t5.
- the control device 15 determines that the image position of the Handle 12A lies in the captured image IMG5 in the interval Z2, which is why the image IMG5 is stored in the memory space allocated to the interval Z2.
- the camera 20 captures and outputs an image stream, that is, captures and outputs images at a predetermined frame rate.
- the frame rate is, for example, between 1 FPS (FPS: frame per second) up to 30 FPS, preferably between 10 FPS and 15 FPS.
- FPS frame per second
- the currently recorded image is saved in each case.
- a total of 100 images are captured in the 10 seconds at a frame rate of, for example, 10 FPS. Of these 100 images, only the last captured image is saved permanently. It can be provided that each of the images is first saved and then overwritten by the following image, or the images are initially held in a buffer memory until the washware holder 122 is moved further and the most up-to-date image for the respective pull-out position is thus known.
- the flushing program is started. Then first the load of the items to be cleaned 12 (and the other items to be washed 13, 14, if any) is determined. If there are images with different time stamps, that is to say with different actuality, for different sub-areas W1-W4 (see FIG. 5), the respective most up-to-date image IMG is analyzed for a respective sub-area W1-W4.
- the most recent image IMG5 (time t5), which is stored in the memory space assigned to the interval Z2, shows, for example, a partial area W2 of the washware receptacle 12.
- the rearmost area of the washware receptacle 12 is not visible on this image IMG5.
- the image IMG4 (time t4), which is stored in the memory location assigned to the interval Z1, shows the entire washware receptacle 12 (partial area W1).
- the image IMG3 (time t3), which is stored in the memory space assigned to the interval Z3, shows a sub-area W3 of the washware receptacle 12.
- This sub-area W3 is comprised of both the sub-area W2 and the sub-area W1. Since the recording time t3 of the image IMG 3 is older than the recording time of the images IMG4 and IMG5, the image IMG3 is not analyzed since it has outdated information in comparison. Image IMG5 is used to determine the load for the partial load area W2 of the washware receptacle 12 is used and the image IMG4 is used to determine the load for the partial area (W1-W2) not visible on the image IMG5, as explained below with reference to FIG.
- the loading is preferably determined by analyzing the entire image and then extracting the relevant areas. It is also possible to extract the sub-areas and merge them into one image, which is then analyzed, but artefacts and distortions can occur because the images were acquired at different points in time, which can affect the analysis.
- FIG. 7 schematically shows a result RES of a loading determination, with different images IMG4, IMG5 (see FIG. 6) being used for different partial areas W2, W1-W2.
- the result RES includes two partial results RES1 and RES2.
- the first partial result RES1 results from an analysis of the image IMG5, on which only the partial area W2 is visible.
- the part of the result of the analysis of the image IMG5 that does not relate to the washware receptacle 12 but, for example, to the door 3 is discarded.
- the second partial result RES2 results from an analysis of the image IMG4.
- the parts of the result of the analysis of the image IMG4 relating to the sub-area W2 are discarded since there is a more recent image IMG4 for this sub-area and only the part of the result relating to the area W1-W2 becomes , used.
- the overall result RES is made up of the partial results RES1, RES2.
- Fig. 8 shows a schematic block diagram of a further exemplary embodiment of a system 100.
- the system 100 comprises an image analysis unit 25 arranged externally to a dishwasher 1 (for example the domestic dishwasher of Fig. 1 without the image analysis unit shown there).
- the dishwasher comprises a communication device 16 , by means of which the control device 15 (see FIG. 1) is set up to transmit images IMG to the image analysis unit 25 and to receive a result of a loading determination RES from the image analysis unit 25.
- the image analysis unit 25 has a corresponding communication device 26 .
- the communication devices 16, 26 are designed, for example, as a modem, as a WLAN adapter, and/or as a mobile radio modem.
- Fig. 9 shows a schematic block diagram of an exemplary embodiment of a method for operating a dishwasher 1, for example the domestic dishwasher of Fig. 1.
- a first step S1 an image IMG (see Fig. 2) of at least a partial area W1 - W4 (see 5) of a wash item holder 12 (see FIGS. 1-4) of the dishwasher 1 as a function of an extension position Z1-Z4 (see FIGS. 3-5) of the wash item holder 12.
- the pull-out position Z1-Z4 of the washware receptacle 12 at the time t1-15 (see FIG. 5) of the image acquisition is determined.
- a third step S3 the image IMG is stored in one of a number of memory locations assigned to the excerpt position Z1-Z4, with each memory location of the number being assigned a set of excerpt positions Z1-Z4.
