Abstract
Description
Technical Field
[0001] This invention relates to household dishwashers and methods for operating household dishwashers. Background Technology
[0002] The dishwasher includes a washing container for holding items to be washed. Multiple item receiving sections can be provided within the washing container, and items can be contained within these sections. The item receiving sections can be removed from and returned to the washing container. A holding device for retaining the items can be provided on these item receiving sections. This holding device is suitable for vertically holding long-necked items, such as refillable water bottles, beverage bottles, baby bottles, vases, etc., within the item receiving sections so that a jet of spray from the spray arm can enter the item to be cleaned through an opening, such as the neck of the bottle, thereby cleaning the item.
[0003] The challenge with cleaning such items in bottles lies in ensuring a sufficient amount of detergent and / or fresh water enters the bottle from the spray arm and thoroughly cleans even the bottom of tall bottles from the inside. Furthermore, the wide variety of bottle sizes and shapes available globally, as well as the possibility that users will leave the device freely placed within the cleaning container, must be considered.
[0004] Based on internal professional experience, the known specific location and center of the bottle bottleneck means that the bottle neck or opening should be positioned as directly above the rotating spray arm as possible. However, this principle cannot reliably function if the user does not place the retainer exactly as instructed, the cleaning material is not placed exactly as instructed, the size and shape of the cleaning material are not up to standard or do not correspond to the construction of the retainer, and / or the cleaning jet fails to precisely enter the opening of the cleaning material due to component tolerances of the cleaning system. All of these situations will result in the cleaning material not being rinsed sufficiently. This is especially true for the inside of the bottle, making it impossible to clean the inside of the bottle cleanly or hygienically without leaving any residue. Summary of the Invention
[0005] In this context, one object of the present invention is to provide an improved household dishwasher.
[0006] Therefore, a household dishwasher is proposed, comprising a laundry container, a holding device for holding the laundry in or above the laundry container, an actively driven spray arm, and open-loop and closed-loop controllers. The open-loop and closed-loop controllers are designed to influence the rotational movement of the spray arm according to the position of the holding device in or above the laundry container, causing the spray arm to pause near the holding device to apply detergent and / or fresh water to the laundry held by the holding device.
[0007] Because the spray arm pauses near the retaining device, cleaning fluid and / or fresh water can be specifically sprayed into the openings of the item being cleaned. This consistently ensures reliable cleaning of the item. Therefore, regardless of component tolerances, for any geometry of the item being cleaned, especially very narrow bottlenecks, and even for items of any shape, the item can always be cleaned reliably and hygienically, regardless of how the user positions the retaining device.
[0008] Household dishwashers include a washing container that can accommodate multiple dish compartments, particularly a lower dish compartment or lower basket, an upper dish compartment or upper basket, and a dish drawer. Each dish compartment may include one or more retaining devices. The dish compartment can be removed from the washing container along its extension direction and moved back into the washing container along its insertion direction. However, only one type of dish compartment will be discussed below. This dish compartment is basket-shaped and consists of a large number of interconnected metal wires. The retaining devices may have a barbed or nail-like geometry. For example, the retaining devices may be clamped, snapped, or suspended into the dish compartment.
[0009] In this context, "actively driven" spray arms mean that the spray arms are equipped with a drive element, particularly an electric motor, which drives the spray arms, especially the arms themselves. In contrast, "passively driven" spray arms have no drive element. Passively driven spray arms can be driven, for example, by detergent and / or fresh water sprayed from nozzles on the spray arms. The boom is actively driven. In addition to the boom, the spray arms may also include spray arm satellites rotatably supported on the boom. Unlike the boom, the spray arm satellites are preferably passively driven. For this purpose, the spray arm satellites may include drive nozzles from which detergent and / or fresh water are sprayed.
[0010] The open-loop and closed-loop controllers can be those for a household dishwasher. One or more washing programs for the dishwasher can be stored in the open-loop and closed-loop controllers. The open-loop and closed-loop controllers interact with and control the drive elements. Here, the way the open-loop and closed-loop controllers "influence" the rotational movement of the spray arm or boom based on the position of the holding device can be understood as slowing down, accelerating, reversing, and / or stopping the spray arm or boom.
[0011] The situation where the spray arm is paused "near" the holding device specifically means that the spray arm is configured such that at least one spray ring of the spray arm's nozzle intersects with the opening of the object being cleaned. In this case, the situation where the spray arm "loads" the object being cleaned with washing liquid and / or fresh water specifically means that the spray arm wets the object being cleaned with washing liquid and / or fresh water in order to clean the object.
[0012] Here, the "pause" of the spray arm can be understood in particular as a brief cessation of its rotational movement, with the arm remaining still for a fraction of a second to a few seconds. However, "pause" also includes a complete reversal of the rotational direction, where the rotation is reversed, for example, from clockwise to counterclockwise, or vice versa. In the last mentioned case, "pause" should be understood specifically as the precise point in time at which the rotational direction is reversed.
[0013] According to one design, the spray arm includes a boom and spray arm satellites rotatably supported on the boom, wherein open-loop and closed-loop controllers are designed to influence the rotational movement of the boom based on the position of the holding device within or above the cleaning container, causing the spray arm satellites to pause near the holding device in order to apply detergent and / or fresh water to the cleaning container held by the holding device.
[0014] Therefore, a household dishwasher is proposed, comprising a laundry container, a holding device fixed in or above the laundry container for holding the laundry, an actively driven spray arm, and open-loop and closed-loop controllers. The spray arm includes a boom and spray arm satellites rotatably supported on the boom. The open-loop and closed-loop controllers are configured to influence the rotational movement of the boom based on the position of the holding device in or above the laundry container, causing the spray arm satellites to pause near the holding device to apply detergent and / or fresh water to the laundry held by the holding device. Specifically, "pausing" the spray arm satellites near the holding device means that the spray arm satellites, as rotating units, are held in their current position relative to the holding device for a short time, e.g., a fraction of a second to a few seconds, while the spray arm satellites themselves continue to rotate. On the other hand, the boom is preferably paused briefly. This specifically means that the boom with the rotating spray arm satellites pauses near the holding device to apply detergent and / or fresh water to the laundry held by the holding device. "Pause" does not preclude the possibility that the spray arm satellite component itself may continue to rotate during the pause.
[0015] According to another design, the spray arm satellites pause at multiple different locations, and then move to these locations sequentially.
[0016] For example, three distinct locations could be provided. However, the number of locations is essentially arbitrary. For instance, the spray arm satellites could pause for a few seconds at each location. Providing multiple locations ensures that sufficient detergent and / or fresh water enters the cleaned material through the openings to thoroughly clean it.
[0017] According to another design, the spray arm satellite component pauses at a first end position and a second end position different from the first end position, and the spray arm satellite component moves back and forth between the end positions.
[0018] For example, the spray arm satellites remain in their respective end positions for a few seconds. The spray arm satellites then move back and forth between the two end positions in a wiping motion.
[0019] According to another design, the household dishwasher is designed to detect the position of the holding device.
[0020] For this purpose, a household dishwasher may include a corresponding detector or sensor.
[0021] According to another design, the household dishwasher has a position sensor and / or camera for detecting the position of the holding device.
[0022] The position sensor can be, for example, a magnetic sensor. The position sensor can be fixed to the cleaning container or the cleaning material receiving section. A camera can also be fixed to the cleaning container or the cleaning material receiving section. The position of the holding device can also be detected by friction contact, carrier needles, etc. Furthermore, the position of the holding device can be determined by load inquiries into the rotating spray arm (especially the drive element) and by relevant local load changes on the holding device (e.g., by magnetic force).
[0023] According to another design, the household dishwasher interacts with an external mobile device to detect the position of the holding device.
[0024] External mobile devices can be, for example, mobile phones, especially smartphones and tablets. For instance, the position of the retaining device can be determined by the user inputting its location via a mobile application on the mobile device. Furthermore, automatic optical recognition can be performed using mobile devices, particularly their cameras. Camera data from the mobile device can also be used to detect the load on the cleaning materials.
[0025] According to another design, the position of the retaining device within or above the cleaning container can be arbitrarily selected.
[0026] This means that users can place the retaining device anywhere within or above the laundry container. For example, the retaining device can be suspended, locked, or clipped into the laundry container. Alternatively, the retaining device or multiple retaining devices can be permanently fixed to the laundry container.
[0027] According to another design, the household dishwasher includes a drive element for driving the spray arm, wherein open-loop and closed-loop controllers are designed to control the drive element to affect the rotational movement of the spray arm.
[0028] Specifically, open-loop and closed-loop controllers are designed to drive the drive element to influence the rotational movement of the spray arm. As mentioned earlier, the drive element can be an electric motor. For example, open-loop and closed-loop controllers can control or adjust the speed of the drive element as needed. Furthermore, open-loop and closed-loop controllers can also change the rotational direction of the drive element as needed. Open-loop and closed-loop controllers can also stop or lock the drive element to stop the spray arm satellite components.
[0029] Furthermore, a method for operating a household dishwasher is proposed, the dishwasher having a laundry container, a holding device fixed in or above the laundry container for holding the laundry, an actively driven spray arm, and open-loop and closed-loop controllers. The method includes the steps of: a) detecting the position of the holding device in or above the laundry container, and b) influencing the rotational movement of the spray arm according to the position of the holding device by means of the open-loop and closed-loop controllers, such that the spray arm pauses near the holding device to apply detergent and / or fresh water to the laundry held by the holding device.
[0030] The spray arm, or spray arm satellites only, can be paused, for example, once or several times during the cleaning process. Detecting or recording the position of the holding device within or above the cleaning container can be accomplished using the aforementioned mobile device, position sensor, and / or camera. Open-loop and closed-loop controllers communicate with the mobile device, position sensor, and / or camera. Appropriate interfaces can be provided for this purpose. Communication can be wireless or wired. The rotational movement of the boom is influenced based on data regarding the position of the holding device provided by the mobile device, position sensor, and / or camera.
[0031] According to one design, the spray arm includes a boom and spray arm satellites rotatably supported on the boom, wherein in step b), the rotational movement of the boom is influenced by open-loop and closed-loop controllers based on the position of the boom. When the spray arm satellites approach a holding device, the holding device pauses, thereby applying washing liquid and / or fresh water to the cleaning material held by the holding device.
[0032] This means that a method for operating a household dishwasher is particularly preferred, the dishwasher having a laundry container, a holding device fixed in or above the laundry container for holding the laundry, an actively driven spray arm, and open-loop and closed-loop controllers, the spray arm including a boom and spray arm satellites rotatably supported on the boom. Therefore, the method includes the steps of: a) detecting the position of the holding device in or above the laundry container, and b) influencing the rotational movement of the boom by means of the open-loop and closed-loop controllers according to the position of the holding device, so that the spray arm satellites pause near the holding device to supply detergent and / or fresh water to the laundry held by the holding device.
[0033] According to another design, the spray arm satellites pause at multiple different locations, during which the spray arm satellites move sequentially to these locations.
[0034] According to another design, the spray arm satellite component pauses at a first end position and a second end position different from the first end position, and the spray arm satellite component moves back and forth between the end positions.
[0035] The above two operating states can be selected: the spray arm satellite component can be paused at multiple different positions, or the spray arm satellite component can move back and forth between the first end position and the second end position. For example, this can be selected by appropriately choosing a rinsing or cleaning program.
[0036] Other possible implementations of the household dishwasher and / or method include combinations of features or embodiments described above or below with reference to embodiments not explicitly mentioned. Those skilled in the art will also add various aspects as improvements or supplements to the corresponding basic forms of the household dishwasher and / or method.

[0044] Unless otherwise stated, the same or functionally equivalent elements in the figures are given the same reference numerals.
[0045] Figure 1 A schematic perspective view of an embodiment of a household dishwasher 1 is shown. The household dishwasher 1 includes a washing container 2, which can be closed by a door 3, which is particularly waterproof. For this purpose, a sealing device can be provided between the door 3 and the washing container 2. The washing container 2 is preferably cuboid. The washing container 2 can be arranged inside the housing of the household dishwasher 1. The washing container 2 and the door 3 can form a washing space 4 for washing the items to be washed.
[0046] exist Figure 1 In the image, door 3 is shown in its open position. Door 3 can be closed or opened by pivoting about a pivot axis 5 located at its lower end. The loading opening 6 of the washing container 2 can be closed or opened via door 3. The washing container 2 has a base plate 7, a top plate 8 opposite to the base plate 7, a rear wall 9 opposite to the closed door 3, and two side walls 10 and 11 opposite to each other. The base plate 7, top plate 8, rear wall 9, and side walls 10 and 11 can be made of, for example, stainless steel. Alternatively, the base plate 7 can be made of, for example, plastic material.
[0047] The household dishwasher 1 also has at least one dish receiving compartment 12 to 14. Preferably, several, for example, three dish receiving compartments 12 to 14 can be provided, wherein dish receiving compartment 12 is a lower dish receiving compartment or lower basket, dish receiving compartment 13 is an upper dish receiving compartment or upper basket, and dish receiving compartment 14 is a dish drawer. Also, Figure 1 As shown, the cleaning material receiving portions 12 to 14 are arranged stacked vertically within the cleaning container 2. Each cleaning material receiving portion 12 to 14 can be moved into or out of the cleaning container 2. Specifically, each cleaning material receiving portion 12 to 14 can be pushed into or moved into the cleaning container 2 along the insertion direction E, and can be moved out or pushed out of the cleaning container 2 along the extraction direction A, which is opposite to the insertion direction E.
[0048] Figure 2 A schematic side view of an embodiment of a spraying device 15 for a household dishwasher 1 is shown. The spraying device 15 is preferably disposed on the base plate 7 of the washing container 2. The spraying device 15 includes a rotatably mounted spraying arm 16 with a suspension rod 17 and spraying arm satellites 18 rotatably supported on the suspension rod 17. The suspension rod 17 is rotatably supported about a first axis of rotation 19 on a pump tank 20 of the household dishwasher 1. The pump tank 20 is disposed on the base plate 7. The pump tank 20 is covered by a sieving system 21. The sieving system 21 may include a coarse screen and a fine screen. The fine screen is a flat screen or may represent a flat screen.
[0049] The spray arm satellite 18 is rotatably supported on the boom 17 about a second rotation axis 22. The rotation axes 19 and 22 are arranged parallel to each other and spaced apart. The spray arm satellite 18 has an upper side 23 facing away from the base plate 7 and a lower side 24 facing the base plate 7. A plurality of nozzles 25 are disposed on the upper side 23, facing away from the base plate 7 and towards the top plate 8. Figure 2 In the figure, only one of the nozzles 25 is marked with an attached figure.
[0050] Nozzle 25 is adapted to generate jet stream 26, by means of which washing liquid and / or fresh water F can be applied to the object being cleaned (not shown). Specifically, nozzle 25 is provided only on the top side of spray arm satellite 18. Alternatively, nozzle 25 may be arranged such that they point in the direction of base plate 7. In addition, spray arm satellite 18 may also have nozzle 25 on both the top and bottom sides.
[0051] Spray arm satellite component 18 has multiple arms 27 to 29 ( Figure 4 The number of arms 27 to 29 is arbitrary. For example, three such arms 27 to 29 can be arranged at circumferential angles spaced 120° apart from each other.
[0052] The boom 17 includes a first arm 30, on which a spray arm satellite 18 is rotatably supported about a second axis of rotation 22. Furthermore, the boom 17 includes a second arm 31. When viewed along a first axis of rotation 19, the first arm 30 and the second arm 31 are positioned at different heights. Specifically, the first arm 30 is positioned closer to the base plate 7 than the second arm 31.
[0053] The boom 17 may also have additional nozzles. However, this is not absolutely necessary. The boom 17 is actively driven. In this case, "actively driven" should be understood as the drive element 32 associated with the spray arm 16, and in particular the boom 17, including, for example, an electric motor. The drive element 32 is adapted to rotate the boom 17 about a first axis of rotation 19.
[0054] In contrast, the spray arm satellite 18 is not actively driven. Specifically, the spray arm satellite 18 rotates by means of a jet stream 26 ejected from the nozzle 25. Special drive nozzles may also be provided on the spray arm satellite 18.
[0055] Figure 3 A schematic top view of an embodiment of the cleaning material container 12 is shown. Cleaning material containers 13 and 14 may be constructed identically to cleaning material container 12. However, only the cleaning material container 12 will be discussed below. However, all statements regarding the cleaning material container 12 can be applied accordingly to the cleaning material containers 13 and 14. Figure 3 In this orientation, the spraying device 15 or spraying arm 16 is arranged below the cleaning material receiving section 12. However, Figure 3The spraying device 15 is not shown in the diagram.
[0056] The cleaning material receiving section 12 consists of a large number of interconnected (e.g., welded) metal wires 33, 34. Figure 3 In the diagram, only two parallel metal wires 33 and 34 are each marked with reference numerals. The cleaning container 12 includes a holding device 35. The holding device 35 is adapted to hold the cleaning item 36 vertically in the cleaning item container 12, such as a refillable water bottle, beverage bottle, baby bottle, vase, etc., so that the jet stream 26 enters the cleaning item 36 through the opening 37, such as the neck of the bottle, thereby cleaning it. The cleaning item 36 particularly includes narrow-necked bottles.
[0057] The challenge with this bottle-shaped cleaning solution 36 is ensuring that a sufficient amount of cleaning fluid and / or fresh water F enters the interior of the bottle from the spray arm 16, and that, in the case of a tall bottle, the bottom of the bottle is also adequately cleaned from the inside. Furthermore, the wide variety of bottle sizes and shapes available globally, as well as the possibility of users freely placing the cleaning solution 36 and / or the holding device 35 within the cleaning solution 12, must be considered.
[0058] The retaining device 35 may be a bottle holder. The retaining device 35 may also be referred to as a retaining and / or centering aid. The retaining device 35 itself can be installed by the user into or above the item receiving portion 12 and then removed from there again. For example, the retaining device 35 may be hooked, latched, or clamped into wires 33, 34. Optionally, the retaining device 35 or multiple retaining devices 35 may be fixed in a fixed position on the item receiving portion 12. The retaining device 35 may have a nail-like geometry that can be inserted into the opening 37 of the item 36 to hold the item 36 upright in the item receiving portion 12.
[0059] The household dishwasher 1 is designed to detect the position P of the retaining device 35 within or above the dish receiving section 12. Position P is... Figure 3 The position P is represented by dashed lines. Therefore, the current position P can be understood as the area where the holding device 35 is located. For example, this position can be determined by the user inputting the position P of the holding device 35 via the control panel of the household dishwasher 1 or via a mobile application on the mobile device 38. The mobile device 38 can be, for example, a mobile phone, especially a smartphone or tablet.
[0060] Alternatively, the position P of the holding device 35 can be detected automatically. This can be achieved, for example, by means of a position sensor 39, particularly a magnetic sensor. Optical recognition is also possible. For example, optical detection can be performed using a camera 40, which can also be used to detect the load on the cleaning container 12. Furthermore, optical recognition can be performed using a mobile device 38, particularly its camera. Camera data from the mobile device 38 can also be used for load detection.
[0061] The position P of the holding device 35 can also be detected by rotating the spray arm 16, especially by checking the load of the drive element 32, and by relevant local load changes on the holding device 35 (e.g., by magnetic force, friction contact, carrier needle, etc.).
[0062] To evaluate data from the mobile device 38, position sensor 39, and / or camera 40, the household dishwasher 1 has open-loop and closed-loop controllers 41 that communicate with the mobile device 38, position sensor 39, and / or camera 40. The open-loop and closed-loop controllers 41 are also designed to drive the spraying device 15, particularly the drive element 32 of the spraying device 15. For example, the speed, rotational speed, and / or direction of rotation of the boom 17 can be controlled by means of the open-loop and closed-loop controllers 41.
[0063] Figure 4 Another schematic top view of the cleaning material container 12 is shown. As previously mentioned, the spray arm 16 is located below the cleaning material container 12. Figure 4 The spray arm 16 is shown in three different angular positions or positions P1, P2, and P3.
[0064] To ensure that the detergent and / or fresh water F are adequately applied to the object being cleaned 36, the drive element 32 is controlled by open-loop and closed-loop controllers 41, causing the spray arm 16, particularly the boom 17, to stop at each of several different positions P1, P2, P3, while the spray arm satellite 18 continues to rotate. For example, three positions P1, P2, P3 may be set. However, the number of positions P1, P2, P3 is essentially arbitrary. Different positions P1, P2, P3 can each be held for a few seconds.
[0065] Positions P1, P2, and P3 can be moved once during the cleaning process or passed through multiple times at different stages of the cleaning process. The working ring 42 of the jet stream 26 (only one of which is in…) Figure 4 (As indicated by the attached drawing) The device 35 intersects with the opening 37 of the object to be cleaned 36 at least once at different positions P, allowing sufficient washing liquid and / or fresh water to enter and clean the object 36. Figure 4 In the diagram, opening 37 is shown in three different positions P of the retaining device 35.
[0066] Figure 5 Another schematic top view of the washable container 12 is shown. However, compared with... Figure 4 Instead, the spray arm satellite component 18 does not stop at different positions P1, P2, P3, but moves back and forth between the two end positions P10, P20, as indicated by double arrows 43. This is achieved by appropriately controlling the drive element 32 using the open-loop and closed-loop controller 41. Here, the working loop 42 of the spray arm satellite component 18 also achieves good overlap with the opening 37.
[0067] Therefore, by targeted control of the spray arm 16 based on the detected position P of the retaining device 35, complete rinsing and cleaning of the interior of the item 36 can always be achieved. This can be achieved regardless of where the user places the retaining device 35 on or within the washing container 12. Items 36 of any geometry, especially bottles with very narrow necks, can be reliably cleaned. The cleaning result is independent of the component tolerances of the retaining device 35. Reliable and hygienic cleaning results can always be achieved.
[0068] Figure 6 A schematic block diagram of an embodiment of a method for operating a household dishwasher 1 is shown. In this method, the position P of the holding device 35 in or above the laundry container 12 is detected or recorded in step S1. Detection can be performed by means of a mobile device 38, a position sensor 39, and / or a camera 40. An open-loop and closed-loop controller 41 can take over the evaluation of the recorded data.
[0069] In step S2, based on the detected position P of the holding device 35, the rotational movement of the boom 17 is influenced or controlled by the open-loop and closed-loop controller 41, causing the spray arm satellite 18 to pause near the holding device 35 in order to apply washing liquid and / or fresh water F to the cleaning material 36 held by the holding device 35. Specifically, in step S2, the washing liquid and / or fresh water F is introduced into the cleaning material 36 through the opening 37.
