Description

[0001] Cover unit for covering a camera of a household appliance, household appliance, method for detachably coupling a cover unit and method for detecting a coupled cover unit

[0002] The invention relates to a cover unit for covering a camera of a household appliance, in particular a dishwasher, a household appliance, in particular a dishwasher, a method for detachably coupling a cover unit and a method for detecting a coupled cover unit.

[0003] Optical systems can be used in washing appliances, such as dishwashers, to improve user comfort, ease of use, and washing performance. For example, a camera can be installed inside the dishwasher. This allows for different usage scenarios to be observed and monitored, both with the door closed and with the door open. In particular, by installing the camera in the dishwasher door, people near the dishwasher can also be detected when the door is open.

[0004] DE 10 2019 100 181 A1 and EP 3 932 283 A1 (which falls under Art. 54 (3) EPC) each disclose a dishwasher with a camera and a locking element that can be moved from a locking position covering the camera opening to a working position releasing the camera opening and vice versa.

[0005] The invention aims to provide an improved cover unit for covering a camera of a rinsing device, an improved rinsing device, an improved method for detachably coupling a cover unit, and an improved method for detecting a coupled cover unit.

[0006] According to the invention, this problem is solved by a cover unit for covering a camera of a household appliance, a household appliance, a method for detachably coupling a cover unit, and a method for detecting a coupled cover unit with the features of the main claims. Advantageous embodiments and further developments of the invention are described in the following dependent claims.

[0007] The advantages achievable with the invention include, besides the possibility of covering or switching off the camera depending on the situation, particularly easy application.

[0008] A cover unit for concealing a camera in a household appliance, particularly a dishwasher, is presented. The cover unit comprises a locking element that can be operated by rotation and, additionally or alternatively, a locking element for detachably coupling the cover unit to a counter-locking element located on the camera and, additionally or alternatively, on the household appliance, particularly the dishwasher. The household appliance can be, for example, a dishwasher, in particular a household dishwasher for cleaning dishes, which has at least one camera for monitoring the interior of the dishwasher or for monitoring a cleaning process. Such a camera can be located, for example, in a door to close the interior, in a side wall of the interior, or in the ceiling of the interior.If, for example, a user opens the dishwasher, the camera, especially if it's located in the now-open door, can capture images of the dishwasher's surroundings in addition to the appliance and the dishes inside. If the camera records a person, for instance, this can be perceived as intrusive. Advantageously, the camera can be covered with the cover presented here, preventing it from recording images for a desired period of time, such as while loading the dishwasher. The cover can be attached directly to the camera or to a part of the appliance or dishwasher where the camera is located, using the locking mechanism. When connected, the cover can obscure the camera or at least one of its lenses or viewing windows, thus preventing any camera recordings.In a particularly advantageous embodiment, the cover unit, which can also be referred to as a locking flap, is designed for detachable coupling with the camera or the household appliance, especially a dishwasher. This has the advantage that the cover unit can be completely removed from the household appliance, especially the dishwasher, for example, to allow cleaning of the camera and the cover unit. Furthermore, a detachable cover unit can advantageously be exchanged or replaced flexibly and cost-effectively.

[0009] According to one embodiment, the cover unit can have a locking element designed as a sliding element for insertion into retaining rails of the counter-locking element. For example, guide rails or retaining rails can be arranged on two sides of the camera lens, into which the locking element, or even the entire cover unit (designed, for example, as a slider), can be inserted from above or from the side. Advantageously, the cover unit can thus be completely removed from the camera and cleaning device as needed. Furthermore, both the cover unit and the counter-locking element can be manufactured cost-effectively.

[0010] According to another embodiment, the cover unit can have a locking element that can be designed as a screw-on bayonet fitting. For this purpose, both the locking element and the mating locking element can be circular and have interlocking threads. For example, the locking element can be placed onto the mating locking element, similar to some camera lenses, and securely coupled to it by performing a slight rotation, for example, by about 90 degrees. The screw-on system can be designed to be watertight and may additionally or alternatively include a flushing system in the thread. Advantageously, a bayonet fitting is inexpensive to manufacture, and the cover unit can be securely and reliably attached to the camera by means of a bayonet fitting, while also being easily detachable by the user when needed.

[0011] According to another embodiment, the cover unit can have a locking element that can be designed as a screw-on closure. For example, both the locking element and the mating locking element can be circular and have interlocking threads. Advantageously, a screw closure is inexpensive to manufacture, and the cover unit can be securely and reliably attached to the camera by means of a screw closure, while at the same time being easily detachable by the user when necessary.

[0012] According to another embodiment, the cover unit can have a locking element that can be designed as a hinge with openings for closure. For example, the locking element and the counter-locking element can be constructed with a combined snap / folding hinge and attached to, for example, the viewing window of the camera unit as needed or desired. The locking element can, for example, be first slid onto the hinge device as a so-called clip closure and then folded over the lens. Advantageously, hinges can be manufactured cost-effectively and in a space-saving manner.

[0013] According to a further embodiment, at least the closure element can be made of elastomer. The cover unit can, for example, be made entirely or at least partially of a flexible elastomer. The closure element can thus be easily slipped over the camera lens as desired or required. Appropriate retaining devices on the camera's lens cover can, for example, prevent the closure element from falling off during operation or when the household appliance, particularly a dishwasher, is not running. This embodiment has the advantage that the closure element can be manufactured cost-effectively, is waterproof, and is easy to attach.

[0014] According to another embodiment, the cover unit can be designed with wings that can be rotated into the camera's field of view. For example, the cover unit can have a mechanical shutter iris, comparable to the principle of the eye's pupil or a camera aperture. The mechanism can be arranged, for example, between the camera's viewing lens and a shutter disc of the cover unit. Rotating the shutter disc can then trigger the mechanism for adjusting the shutter elements. A rotation of the shutter disc, for example by 60°, can slide multiple wings in front of the camera unit, thus obscuring its field of view. Alternatively, the shutter elements can also be designed similarly to the construction of an excavator bucket.The triggering, or opening and closing, of the shutter blades can be achieved, for example, by permanent magnets integrated into the rotating shutter disc. If the magnets are positioned precisely in the direction of rotation of the shutter elements, they attract the corresponding magnetically designed shutter elements, thus opening the camera's view. If the shutter element is rotated 90 degrees, the magnets are no longer effective, and the shutter elements can close, for example, by a simple spring tension. This allows for very precise covering of the camera lens.

[0015] Furthermore, a household appliance, in particular a dishwasher, is presented, equipped with a camera and a locking mechanism for detachable coupling with a variant of the previously described cover unit, and additionally or alternatively with a camera featuring a rotary-operated variant of the previously described locking mechanism. Advantageously, the camera of the household appliance, especially the dishwasher, can monitor a process within the appliance, such as a washing cycle, and can also be mechanically deactivated as desired by using the cover unit. For individuals who have purchased the household appliance, especially the dishwasher, with the camera but do not wish to activate it for various reasons, this offers the option of switching off the camera at desired times or permanently using the locking mechanism.

[0016] According to one embodiment, the household appliance, in particular the dishwasher, can include the cover unit coupled to the locking element. For example, the cover unit can be arranged on the camera with a rotatable locking element, or the cover unit can be designed as a flexibly interchangeable accessory for the household appliance, in particular the dishwasher. Advantageously, this allows the dishwasher's camera to be used depending on the situation and user requirements.

[0017] According to another embodiment, the camera can be configured to detect the coupled cover unit. Additionally or alternatively, the cleaning device can have a sensor for detecting the coupled cover unit. For example, a sensor for detecting the locking element can be arranged on the camera. This sensor can, for example, monitor the inserted and / or closed cover unit or flap in order to advantageously deactivate the camera or, conversely, reactivate it. Advantageously, any type of sensor can be used here, for example, an optical sensor that can easily and cost-effectively detect the locking flap.

[0018] Furthermore, a method for detachably coupling a variant of the previously presented cover unit with a counter-locking element of a household appliance, in particular a dishwasher, and additionally or alternatively with a camera of the household appliance, in particular the dishwasher, is presented. The method comprises a step of providing the dishwasher and the cover unit, as well as a step of coupling the locking element of the cover unit with the counter-locking element. Advantageously, this allows the camera to be covered and, for example, simultaneously deactivated, such as during transport of the dishwasher.

[0019] Furthermore, a method for detecting a coupled variant of the previously presented cover unit in a variant of the previously presented household appliance, specifically the dishwasher, is presented. The method comprises a step of sensor-based detection of the cover unit, a step of deactivating the camera when the cover unit is detected, and additionally or alternatively, a step of activating the camera when the cover unit is not detected. For example, the cover unit can be checked by camera at defined time intervals, such as every 24 hours, or at specific key test points, such as under predetermined operating conditions, for example, at the start of a program, after each loading of the dish racks, or after opening the dishwasher door, etc. If the lens is obscured, the camera functions are deactivated within these time intervals or test points.The activation or deactivation of the camera can be displayed on the device's screen and additionally or alternatively transmitted to an external display or control device such as a smartphone. Advantageously, the camera can be operated in an energy-saving manner using this method.

[0020] The approach presented here further provides a device designed to perform, control, and implement the steps of a variant of the method presented herein in appropriate facilities. This embodiment of the invention, in the form of a device, also allows the underlying problem to be solved quickly and efficiently.

[0021] The device can be configured to read input signals and, using these input signals, determine and provide output signals. An input signal can, for example, be a sensor signal readable via an input interface of the device. An output signal can be a control signal or a data signal that can be provided at an output interface of the device. The device can be configured to determine the output signals using a processing instruction implemented in hardware or software. For example, the device can include a logic circuit, an integrated circuit, or a software module and may be implemented as, or comprised of, a discrete component.

[0022] A computer program product or computer program with program code that can be stored on a machine-readable medium such as semiconductor memory, hard disk memory, or optical memory is also advantageous. If the program product or program is executed on a computer or device, it can be used to carry out, implement, and / or control the steps of the method according to one of the embodiments described above.

The cover unit 300 is made of flexible elastomer for illustrative purposes only and is shown in the Figure 16B fitted over the lens 505 of the camera 120. Appropriate retaining devices on the viewing slide prevent the locking element 300 from falling off during operation or when the dishwasher is at a standstill.

[0044] The Figures 17A and 17B Figure 1 shows a schematic representation of a cover unit 300 according to an exemplary embodiment. The cover unit 300 corresponds to or is similar to the one shown in the preceding figures. Figures 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 and 16The cover unit described above differs in that the cover unit 300 shown here is fixedly attached to the camera 120. The cover unit 300 is formed with a plurality of wings 1700, which can be slid into the field of view of the camera 120 by rotation. In other words, the cover unit 300 in this embodiment is formed with a mechanical shutter iris based on the principle of the eye pupil or a camera aperture. By rotating a shutter disc 1705 of the cover unit 300, the mechanism for adjusting the wings 1700, or the shutter elements, can be triggered. A rotation of the shutter disc 1705 by, for example, 60 degrees, pivots all six elements in front of the camera unit and thus obscures its field of view.

[0045] The Figures 18A and 18BFigure 1 shows a schematic cross-sectional view of a coverable camera 120 according to an exemplary embodiment. The camera 120 corresponds to or is similar to the one shown in the preceding figures. Figure 1 , 2 , 3 , 5 , 6 , 8 , 9 , 11 , 12, 13 , 14 , 16 and 17 The camera described above is integrated, but only as an example, into a door 115, which is similar to the one described in the preceding sections. Figure 1 , 2 , 3 , 5 , 6 , 8 , 9 , 11 , 12, 13 , 14 and 16 The described door of a dishwasher corresponds to or resembles it. The camera is 120 in the... Figure 18A shown uncovered while in the Figure 18Bis covered. For illustrative purposes only, in this embodiment, camera 120 is formed by a cover unit 300 with a plurality of wings 1700, which can be slid into a viewing area of ​​the camera 120 by rotation, as already seen, for example, in Figures 17A and 17B The mechanism is described. The mechanism is shown here only as an example, arranged between the viewing window or lens 505 and the shutter window 1705.

[0046] The Figures 19A and 19B Figure 1 shows a schematic cross-sectional view of a coverable camera 120 according to an exemplary embodiment. The camera 120 corresponds to or is similar to the one shown in the preceding figures. Figure 1 , 2 , 3 , 5 , 6 , 8 , 9 , 11 , 12, 13 , 14 , 16, 17 and 18 The camera described above is integrated, but only as an example, into a door 115, which is similar to the one described in the preceding sections. Figure 1 , 2 , 3 ,5 , 6 , 8 , 9 , 11 , 12, 13 , 14 , 16 and 18 The described door of a dishwasher corresponds to or resembles it. The camera is 120 in the... Figure 19A They are shown covered up, while in the Figure 19Bis uncovered. In this exemplary embodiment, the camera 120 is formed by a cover unit 300 with two wings 1700, which can be slid into a viewing area of ​​the camera 120 by rotating the cover unit 300 about an axis 1900. The mechanism is arranged, only by way of example, between the viewing window or lens 505 and the shutter disc 1705. In other words, this figure shows another embodiment for blocking the camera unit by rotating a shutter disc 1705. The locking elements are designed like those in the construction of an excavator bucket. The triggering, or opening and closing, of the buckets can be achieved, for example, as shown here, by the permanent magnets 1905 integrated into the rotatable shutter disc 1705.If the magnets are positioned exactly in the direction of rotation of the shutter elements, they attract the shutter elements (which are only designed to be magnetically compatible for illustrative purposes) and thus open the view of the camera 120. If the shutter element is rotated by 90 degrees, the magnets no longer have an effect and the shutter elements close, for example, by means of a simple spring tension.

[0047] Figure 20Figure 2 shows a flowchart of an embodiment of Method 2000 for the detachable coupling of a cover unit with a counter-locking element of a camera in a cleaning device. Method 2000 comprises step 2005 of providing the cleaning device and the cover unit, and step 2010 of coupling the locking element of the cover unit with the counter-locking element. For illustrative purposes only, step 2010 of coupling is subdivided in this embodiment into three sub-steps 2010A, 2010B, and 2010C. In sub-step 2010C, the cover unit is fixed to the camera by means of a detachable hinge. In the following sub-step 2010B, the cover unit is folded over the camera starting from the hinge, and in sub-step 2010C, it is hooked onto the camera at the end opposite the hinge.

[0048] Figure 21Figure 2100 shows a flowchart of an embodiment of method 2100 for detecting a coupled cover unit in a dishwasher. Method 2100 comprises step 2105 of sensorially detecting the cover unit, step 2110 of deactivating the camera when the cover unit is detected, and step 2115 of activating the camera when the cover unit is not detected. In this embodiment, the cover unit is checked at defined time intervals, for example, 24 hours. If the lens is detected to be obscured, the camera functions are deactivated within these time intervals.

[0049] In another embodiment, the method can also comprise only the steps of detection and deactivation. Additionally or alternatively, the check can also be performed at specific key test points, such as certain operating conditions, for example, at the start of the program, after each loading, etc. Optionally, activation and deactivation of the camera can be displayed on the device screen and additionally or alternatively transmitted to an external display or control device such as a smartphone.
