Description

[0001] The invention relates to a dishwashing arrangement according to the preamble of claim 1. This arrangement, in the manner of a top-loading dishwasher, comprises a sink with an opening at the top and a dish rack, such as a stand for dishes and cutlery, which can be attached to the sink. Furthermore, the dishwashing arrangement includes a dishwasher unit for automatic dishwashing, comprising a spray device directed towards the dish rack and a lid by means of which the opening of the sink can be closed, particularly during a washing cycle.

[0002] From DE 603 ​​15 751 T2, a dishwasher arranged within a sink is known. The dishwasher forms its own wash chamber into which a basket can be inserted from above. A sprayer is attached to the basket, which has a spray fluid inlet. When the basket is inserted into the wash chamber, the spray fluid inlet is connected to a fluid line via a self-aligning coupling, the self-aligning coupling being installed in the sink.

[0003] A disadvantage of the known dishwashing arrangement is that, due to the required self-aligning coupling in the sink, it results in very high installation effort and high manufacturing costs. Furthermore, the known design requires two dishwashing basins, and the basin on the dishwasher side cannot be used for handwashing.

[0004] The object of the invention is to provide a generic dishwashing arrangement that avoids the aforementioned disadvantages and enables cost-effective manufacturing and easy installation.

[0005] This problem is solved by a dishwashing arrangement with the features of claim 1. A supply line section is held or routed on the lid, to which the spray device can be fluidically connected so that it can be supplied with a washing liquid, such as water, via the supply line. This allows the spray device and the entire dishwashing unit to be supplied with the washing liquid via the lid or from above. The sectioned routing of the supply line on the lid enables a very simple and cost-effective connection of the spray device to the supply line. Furthermore, this also allows the dishwashing unit to be designed and used particularly easily as a retrofittable unit.

[0006] In a particularly advantageous embodiment, the spray device has connecting elements and the supply line section has an adjustable supply connection which is connected to the connecting elements in a supply position and disconnected from them in a disconnect position. The adjustable supply connection thus allows the dishwasher equipment to be connected to or disconnected from the supply line as needed, making it particularly easy to prepare the dishwashing arrangement for use with a dishwasher or for handwashing.

[0007] It is advantageous if the supply connection can be adjusted between the supply and disconnect positions by pivoting the cover. This allows the spray device to be easily connected to or disconnected from the supply connection via the connecting elements. Alternatively or additionally to this semi-automatic coupling, the supply connection and / or the connecting elements can also be designed for manual connection.

[0008] Advantageously, the spray device has a lower spray unit that is held against the dish holder. This allows the lower spray unit and the dish holder to be handled as a single unit and inserted into or removed from the dishwasher sink.

[0009] Furthermore, it is advantageous if the lower spray device is movable and held on the underside of the dish holder to enable particularly effective cleaning of the dishes.

[0010] Alternatively or additionally, the spray device has an upper spray mechanism that is held on the lid to enable thorough cleaning of the dishes, especially in their upper area.

[0011] It is advantageous if the upper spray device is movable and held on the underside of the lid to enable particularly effective cleaning.

[0012] In a particularly advantageous embodiment, the lower spray device is directed upwards from the underside of the dish basket and the upper spray device is directed downwards from the lid towards the dish basket in order to ensure complete cleaning of the dishes held.

[0013] Advantageously, the dish rack is also made up of a removable dish basket. This allows the dish rack to be easily removed from the sink when needed, for example, to use it for handwashing.

[0014] In a particularly preferred embodiment of the dishwashing arrangement, the lid has an integrated shallow basin. This allows the lid to be used to collect, retain, and drain washing liquid or water even when the basin opening of the dishwashing basin is closed, particularly during use of the dishwasher. This enables the dishwashing arrangement to be used for handwashing simultaneously with the lid closed, or during a machine wash cycle.

[0015] Advantageously, the dishwashing sink and the shallow basin can be supplied with a single water jet via a shared tap, with the supply pressure at the tap being switchable between the sink supply pressure and a lower shallow basin supply pressure. This ensures that an appropriate supply pressure is available for each basin depth. This allows, for example, the higher supply pressure when using the dishwashing sink to fill it quickly via the tap. Furthermore, when using the shallow basin, the lower supply pressure prevents it from overflowing or the water jet from splashing out uncontrollably.

[0016] It is particularly advantageous if the supply pressure can be automatically switched between the sink supply pressure and the shallow basin supply pressure depending on the pivot position of the lid. This automatic adjustment of the supply pressure prevents, in particular, an excessively high supply pressure when using the shallow basin, which would cause the water jet to splash out of the basin when the tap is opened.

[0017] In a further preferred embodiment, the lid has two lid parts that can be pivoted relative to each other. These parts can be folded against each other in a receiving position spaced apart from the basin opening, forming a largely enclosed receiving space in which the upper spray device can be accommodated. In this way, when the dishwasher attachment is not in use, the upper spray device can be stored in the receiving space of the folded lid, keeping it out of sight and protected. Furthermore, the lower spray device, which is attached to the dish holder, can also be removed from the dishwashing basin along with the dish holder, thus making the basin fully available for handwashing.Alternatively or additionally, the dish holder can also be designed to be foldable, so that it can be placed in a space-saving storage position inside and / or outside the dishwashing sink, in particular by means of a fan-like folding mechanism.

[0018] Advantageously, at least one of the spray nozzles can also be supplied with steam, so that the dishes to be cleaned in the dish rack can be sprayed with steam during the washing process, either as an alternative or in addition to a water jet. This further enhances the cleaning performance of the dishwasher.

[0019] Furthermore, the aforementioned problem is solved by a dishwasher adapter for insertion into an existing sink with a top-mounted opening to create a dishwasher arrangement in one of the aforementioned embodiments, wherein the dish holder and the dishwasher equipment are integrated into a retrofit unit that has an outer contour suitable for insertion into a standard sink. This makes it possible to easily and cost-effectively retrofit existing sinks for handwashing to also allow machine washing.

[0020] It should be noted that all the features of the object according to the invention described above are interchangeable or combinable with each other, provided that such an exchange or combination is not excluded for technical reasons.

[0021] The figures illustrate an exemplary embodiment of the invention. They show: Fig. 1 a perspective view of a dishwashing arrangement according to the invention with a dish holder inserted in a dishwashing sink, Fig. 2 a perspective view of the dishwashing arrangement according to Fig. 1 with dish rack removed from the dishwasher sink, Fig. 3. A perspective view of the dishwashing arrangement during a machine washing process. Fig. 4 a side view of the dishwashing arrangement according to Fig. 1 and Fig. 5 an alternative embodiment of the dishwashing arrangement with a hinged lid.

[0022] The Fig. 1 and Fig. Figure 2 shows a dishwashing arrangement 2 with a dishwashing basin 6 recessed into a worktop 4, which has a basin opening 8 on its upper side, and with a dish holder 10, for example formed by a dish basket, which can be inserted into the dishwashing basin 6 and serves to hold dishes to be cleaned (not shown). As in Fig. As shown in Figure 2, the dish holder 10 can be removed from the dishwashing basin 6 and placed, for example, on the worktop 4, in order to make the dishwashing basin 6 available for handwashing, for example.

[0023] Furthermore, the dishwashing arrangement 2 has a total of 12 dishwasher equipment, which includes a spray device 14 that can be directed towards the dish holder 10 and a lid 16 with which the basin opening 8 can be covered. Fig. 3 can be closed.

[0024] As from Fig. As can be seen from Figure 2, the spray device 14 has a lower spray assembly 20, which is held on a mounting base 18 of the dish holder 10 and is directed upwards towards the dish holder 10 with several lower spray nozzles 22. The lower spray assembly 20 is preferably mounted on the dish holder 10 in a way that allows it to be moved, for example in the form of a rotatable or laterally movable spray arm.

[0025] Alternatively or in addition to the lower spray device 20, the spray device 14 can be used, as shown in Fig. Figure 2 further shows an upper spray device 24, which is held on the underside 26 of the lid 16 and can be directed downwards towards the dish holder 10 with several upper spray nozzles 28. The upper spray device 24 is preferably mounted on the lid 16 in a way that allows it to be moved, for example in the form of a rotatable or laterally movable spray arm.

[0026] As in Fig. 1 and Fig. As shown in Figure 2, a supply line section 30 is laid on the cover 16, which connects the upper spray device 24 with a supply line 32 for spray liquid, such as fresh water in particular.

[0027] As from Fig. 1 and Fig. As can also be seen in Figure 2, the supply line section 30 is also connected to a supply connection 34, which is likewise held on the cover 16. Furthermore, connecting elements 36 are arranged on the dish holder 10, which are connected to the lower spray device 20. The supply connection 34 is positioned on the cover 16 such that it can be connected by pivoting the cover from the illustrated disconnect position to a supply position as shown. Fig. 3 can be moved into position 3, in which the supply connection 34 is connected to the connecting means 36. In this way, in the supply position, in addition to the upper spray device 24, the lower spray device 20 is also connected to the supply line 32 via the supply line section 30 and can be supplied with rinsing fluid from it during a machine rinsing process.

[0028] As especially from Fig. As can be seen from Figure 3, a shallow basin 40 is integrated or recessed into the upper surface of the lid 38. When the basin opening 8 is closed, or when the dishwashing arrangement 2 is in a state ready for a machine wash cycle, this basin can be used to collect and drain washing liquid from a tap 42, for example, for handwashing, which can now be carried out independently of the actual dishwashing basin. The shallow basin 40 has its own drain (not shown) for draining the resulting washing liquid, which, for example, leads into the dishwashing basin 6 or can be directly connected to a drain line.

[0029] As from Fig. As can be seen in Figure 4, both the supply line section 30 of the cover 16 and the tap 42 are connected to the supply line 32, shown in dashed lines, which is designed as a fresh water line with the flow direction indicated by arrows. A pressure control device 44 is installed upstream of the tap 42, by means of which the supply pressure at the tap 42 can be adjusted between a sink supply pressure and a lower shallow basin supply pressure. For this purpose, the pressure control device 44 can be connected to the cover 16 or its bearing via a mechanical, electrical, or electronic control connection 46 and automatically switches between the sink supply pressure and the shallow basin supply pressure depending on the cover's pivot position.This allows, in particular, the rapid filling of the dishwashing basin 6 with a water jet generated by the tap 42 at relatively high pressure when the lid 16 is open, while when the lid 16 is closed, splashing of the washing liquid from the shallow basin 40 can be avoided by a relatively low pressure of the water jet generated by the tap 42.

[0030] As from Fig. As can also be seen from section 4, the supply line section 34 can also be connected to a steam generating unit 48. This unit can supply the spray device 14 with steam so that the dishes to be cleaned can be sprayed with steam via the lower and / or upper spray device during a machine washing process, thereby achieving a better cleaning result.

[0031] Furthermore, according to Fig. 4. A drain 50 of the dishwashing basin 6 is connected to a diverter valve 52, which connects the drain 50 in a drain position to a drain line 54, through which the washing liquid generated during a machine washing cycle can flow freely. Alternatively, the diverter valve 52 can be switched to a return position, in which the washing liquid generated during a machine washing cycle can be returned to the supply line section 30 via a return line 56 and the supply line 32 to enable water-saving circulation. The switching of the diverter valve 52 can be carried out by a control device (not shown).

[0032] Fig.Figure 5 shows a further embodiment of the dishwashing arrangement 2, in which the lid 16 has two lid parts 60A, 60B that can be pivoted relative to each other. In an illustrated receiving position, in which they are spaced apart from the basin opening 8, these parts can be pivoted relative to each other according to arrow S and placed against each other, forming a receiving space 62. The upper washing device 24 can thus be protected and largely concealed within this receiving space 62.

[0033] Regardless of the specific embodiment, at least the dish holder 10 and the dishwasher equipment 12 with the lid 16 and the spray device 14 are preferably integrated into a retrofit unit to form a dishwashing adapter (not shown). The retrofit unit has an outer contour that is adapted in shape and dimensions to standard sinks. This allows a corresponding dishwashing adapter to be inserted into an existing sink 6 to retrofit a dishwashing arrangement according to the invention with minimal installation effort.

[0034] It should be noted that all the features of the object according to the invention described above are interchangeable or combinable with each other, provided that such an exchange or combination is not excluded for technical reasons. QUOTES INCLUDED IN THE DESCRIPTION
