EP2441368B1 - Dishwasher with at least one rotatable spray arm - Google Patents

Description

The invention relates to a dishwasher, in particular a domestic dishwasher, with a rinsing container which has an at least substantially rectangular floor plan with a front side and which is provided with at least one washing basket, in which goods to be cleaned can be held, which is assigned to a respective washing basket, rotatable spray arm can be acted upon with water and / or so-called. Flushing liquor, which is outputable from the spray arm with an upward component, wherein the wash basket at its front, on a front-facing upstanding wall of the washing or on the washing container on its front closing door with at least one receptacle for cleaning agent is provided, in particular according to the preamble of claim 1.

Numerous dishwashers are known, which have a rinsing container with a substantially square outline, for example, when the dishwasher in plan view both in the width and in the depth direction has an extension of about 60 centimeters each.

Lately narrower devices often come on the market compared to the above-mentioned dishwashers, for example, retain the said depth, but have a width of typically 45 or 50 centimeters. Such devices take into account, for example, the increasing number of single households or are sometimes used in the camping area or often in very small kitchens. The overall floor plan of the dishwasher as well as the actual rinsing container for receiving to be cleaned Good is substantially rectangular. In dishwashers with a square floor plan, this floor plan can be acted upon evenly by water and / or detergent, circulating water, so-called rinsing liquor, by a spray arm rotatable about a vertical central axis in the width and depth direction, so that the spray arm moves during its rotary movement equidistant to the front and rear edges as well as to the two side edges of the rectangle present in the special shape of the square.

However, if the rectangle has different edge lengths, a centrally mounted spray arm can only have a length that is smaller than the shortest edge length. In a narrowed in the above-mentioned device, this means that the spray arm during its rotation, although up to the side walls can perform an action, but clearly removed from a front wall or door as well as from a rear wall, so there unencumbered areas remain. This not only leads to a reduced wetting there of the material to be cleaned, but also makes it problematic, cleaning agent, in particular in solid form, which is held on a front edge of a washing basket or a front wall or a frequently used front door, from a beam of the To be able to detect the spray arm in order to introduce it into the rinsing liquor. For such cleaning agent, for example, can be present in a tab-collecting tray, which is to be acted upon from below with a jet to bring the cleaning agent in solution.

Dishwashers are known in the prior art, which have a plurality of spray arms in a plane, such as in the DE 101 62 505 A1 is shown. Again, however, a total square area is processed by dividing this area into four similar quadrants and assigning a spray arm to each quadrant. An improvement for a rectangular area with different edge lengths is not achieved. In addition, such an arrangement is very complicated and expensive and leaves a not swept area just in the mid-range area of a front side, where could be about to be acted tab collection tray.

From the DE 90 14 721 U1 a household dishwasher is known, which has at least one, about its vertical axis and in a horizontal plane freely rotatable support arm, at the ends of which two smaller spray arms are also rotatably mounted. It is also pointed out that a spray arm designed in this way can also be used in a 45 cm wide dishwasher for stationary and permanent locking of the support arm.

From the WO 2010/038189 A1 a metering device for cleaning agent in a dishwasher is known, which is positioned on the inside of the door of the dishwasher so that it is regularly applied during operation with cleaning liquid from sprayers.

The invention is based on the problem even with washing containers with different width and depth extension to allow effective cleaning over the surface and also a dissolving held on a narrow side of the rectangle cleaning agent.

The invention solves this problem by a dishwasher with the features of claim 1. Further advantages and features and developments of the invention are set forth in the dependent claims.

The present invention provides a dishwashing machine, in particular a household dishwasher, in which, by virtue of the eccentric arrangement of the spray arm and its offset relative to a central support, along the transverse center of the washing container, a receiving container for detergents, such as a washing machine, arranged at the front end of the washing basket or in the door. a multi-phase tab, in particular for present in solid state detergent, is directly and effectively acted upon by an emerging from the spray arm jet of water and / or rinsing liquor, as by this arrangement, the application in the middle of the farthest reaches to the front. At the same time, a uniform spraying of the entire surface of a washing basket is achieved by an additional spraying system in the rear region of the washing container facing away from the door and in the plane of the spraying arm. The fact that the spray arm and the Zusatzsprühsystem lie in the same plane, also no additional restriction of the clear height below the two systems mentioned caused. For example, a lower basket of the dishwasher according to the invention can be loaded as high as in a conventional dishwasher, despite an additional spray system below an upper basket, without any restrictions.

If the spray arm is displaced so far to the front of the washing container that it maintains an at least almost identical distance during its rotation to this and to transverse walls of the washing container, on the one hand in the front region of the washing container an equally good dishwashing result as in a square base surface can be achieved. On the other hand, it is then also possible to be able to act directly on a collection basket for a tab or a similar container with a jet emerging vertically from a radial end region of the spray arm.

According to the invention, outlet openings of the additional spray system are movable via rotary bodies, the rotary bodies having a significantly smaller diameter than the front spray arm.

In particular, the additional spray system from the same supply line as the spray arm with water and / or rinsing water can be supplied, so that the design effort is minimized. In this case, a common connection piece for the supply of the spray arm and the additional spray system from the common supply line can be provided in a particularly favorable manner in order to ensure a reliable and similar supply of both systems.

Furthermore, the common connecting piece is particularly favorable in terms of height. As a result, the wash basket to be acted upon by the spray arm and the additional spray system on the same level can likewise be easily adjusted in height, without the effectiveness of the application being changed by the height adjustment.

If the spray arm is connected to the connection piece via an inlet pipe which runs in the transverse center of the washing container with a component in the direction of the front side, supply lines of the auxiliary spray system can advantageously branch off symmetrically from the connection pipe and / or from the connection piece, so that equal conditions result on both sides of the transverse center ,

For a narrow installation position, the rinsing container has a rectangular base surface with a longitudinal extension in the depth direction which is larger than its transverse extension, wherein the spray arm can be dimensioned such that it almost completely covers the transverse extension as in a square base surface in its rotational movement.

Such a device with additional spray system can be particularly favorable for the application of a collecting basket for cleaning an upper of at least two Spülkörben assigned, but is also additionally or alternatively usable for a lower basket.

Depending on the requirements, the outlet openings of the additional spray system can be fixed or movable.

When the auxiliary spray system, viewed in the depth direction of the washing container, is located completely behind the movement range of the rotatable spray arm, a collision is ruled out. There must be no offset in several levels one above the other, so that no height restriction arises for the loading space in the washing. The additional spray system may also form another spray arm which is rotatable behind the front spray arm.

The above-explained and / or the other advantageous embodiments and / or developments of the invention, which are set forth in the subclaims, can thereby - except e.g. in the case of clear dependencies or incompatible alternatives - individually or in any combination with each other.

Further advantages and features of the invention and / or their advantageous embodiments and further developments will become apparent from the drawings and described below embodiments of the subject invention.

Elements with the same function and mode of operation are each provided with the same reference numerals in the figures.

In the FIG. 1 Dishwasher 1 shown is a domestic dishwasher and has a particular on its front V of a door 3 - also an upper lid is possible as a door 3 - closable rinse 2 for receiving ware to be processed dishes, pots, cutlery, glasses, cooking utensils u. on. The door 3 can be pivoted open, for example, about a lower horizontal axis 3a (FIG. FIG. 2 ). The items to be washed can be held in at least one washing basket 4, 5; here are exactly two dish racks 4, 5 are provided one above the other in the washing container 2, which is not mandatory. These baskets 4, 5 are about sprayers 6, 7, 8, 9 with Water FW and / or with circulating water, which is mixed with detergent, rinse aid, dirt particles, and / or other additives such as descaler, salts, etc. ... I, so-called. Rinsing liquor S, each acted upon an upward component. These spraying devices 6, 7, 8, 9 are described in more detail below.

Furthermore, the rinsing baskets 4, 5 can be displaced, for example, on rollers 10 forward, so as to reach an access position for the user, in which the rinsing baskets 4, 5 can comfortably load and unload. As webs for the rollers 10 here lateral rails 11 are provided in the washing compartment 2. Furthermore, at the respective front edge levels of the washing baskets 4, 5 pull and push handles to simplify the insertion and removal of the washing baskets 4, 5 may be provided. In the closed position of the door 3 is the or each dish rack 4, 5 in an operating position in the vicinity of one of the closed door 3 opposite the rear wall 22 of the washing container. 2

In the shifted to the front V access position of the at least one crockery basket 4, 5, the drawn door 3 is pivoted down to the front about a horizontal transverse axis 3a and is substantially horizontal, so that the crockery 4, 5 then above the plane of extension of the open door. 3 and be easily accessible to a user, as in FIG. 2 for the upper basket 5 is shown.

According to the illustrated embodiment, the upper washing basket 5, two or more sprayers 7, 9 (or 7, 8 in the alternative embodiment according to Figure 5 to 7 ) in at least almost the same horizontal plane X, Y below an upper here Spülkorbs 5 assigned. The first spraying device 7 in this case comprises a rotatable about a vertical axis of rotation spray arm, the axis of rotation 12 is offset from a central arrangement to the front V, ie from the depth extent Y of the washing forward and thus off-center to the depth extension of the interior of the washing. However, this spraying device 7 is still located in the transverse center plane Q, ie approximately in the middle of the width X of the interior of the washing container. In addition, at least one further spraying device 8 or 9 is provided, which is offset from the first 7 away from the front side V (viewed in the longitudinal direction Y of the washing container) towards the rear wall 22. According to the in FIG. 5 indicated formation, the rear sprayer 8 comprises one or two nozzles 13 which can spray upwards and their spray pattern 14 approximately in FIG. 6 is shown. Alternatively, the rear sprayer 9 may comprise a rotating spray arm, such as in particular Figures 3 and 4 is recognizable. Other rear sprayers are possible. In this case, the front sprayer 7 is arranged in a position offset in the direction of the front V that a front, the door 3 facing the end of the Spülkorbs 5 or arranged in the door 3 receiving or collecting container 27 for cleaning agents, in particular for present in solid form Detergent, such as a multi-phase tab, can be acted upon by a jet of water FW and / or washing liquor S emerging from the spray arm 7. Here, a collecting tray 27 made of, for example, wire mesh or perforated plastic is shown at the top of the washing rack 5, in which the tab is inserted or falls from a container on the inside of the door 3 after its closing. This receptacle 27 can then be acted upon directly upon rotation of the front sprayer 7 via a radially outer nozzle 28. This direct loading and the associated rinsing out of the receiving container 27 can be effected approximately at the radially outer end of the front spray arm 7 by a beam 29 exiting vertically upward, since this is sufficiently long that it extends in its rotation up to just below the collecting container 27 ,

In the illustrated embodiments, the constructive simplification and space-saving arrangement and the at least two sprayers 7 and 8 or 9 by a common, at least substantially horizontal (in the X, Y plane arranged, in particular in the depth direction Y extending) inlet pipe 15 with Water and / or rinsing S supplied by a on the rear wall of the washing in the height direction Z extending feed tube 18. In this inlet pipe 15, here substantially in the transverse center Q, i. about the middle of the width of the extension X of the interior of the washing container 2 in the depth direction Y longitudinally, can at least a separate channel 16, 17 for each of the sprayers 7 and 8 and 9 over the rear part of his extending substantially in Tiefenrichturng Y of the rinse be divided. These channels may run integrally and integrally to the junction of the rear sprayer 8 or 9.

Such a common course of the channels 16 and 17 is, for example, in the version after the lower picture of FIG. 8 possible. At the T-shaped leading branch Z (see also FIG. 5 ) joins there a branch pipe A for a fixed, V- or Y-shaped Zusatzsprüharm 8 with lateral nozzles 13 at. These may be rotatable or fixed on the fixed Zusatzsprüharm 8.

In FIG. 8 on the other hand, in the upper picture, the branch Z is inclined, in particular at an angle of approximately 45 ° with respect to the horizontal inlet pipe 15, so that the admission to the rear spray device 8 or 9 is led out separately already in the initial region of the inlet pipe 15. This solution is aerodynamically particularly favorable. It can easily result in a uniform supply of both sprayers 7 and 8 or 9 at the same diameter of the channels 16, 17.

In the middle picture the FIG. 8 however, the branch Z forms its own outlet from the adapter piece 21, which connects the inlet pipe 15 with a feed tube 18 described in more detail below. Accordingly, here the branch Z also runs approximately horizontally and below the inlet pipe from the adapter piece 21 as a separate line. The branch pipe for the rear spray device 8 or 9 can then run approximately parallel below the inlet pipe 15.

The inlet pipe 15 as well as the feed tube 18, which is essentially vertical to the latter and described in more detail below, can be made, for example, of plastic, in particular polypropylene, optionally with a mineral reinforcement to improve the stability and the resistance to chemical reactions. The directly to the sprayers 7, 8, 9 feeding the inlet pipe 15 may be divided over its axial course in several pieces 19, 20 ( FIG. 3 ), so that the individual pieces can easily be produced as injection-molded parts - even with covered channels 16, 17 and demoldable. These individual channels 16, 17 are particularly advantageous in the surrounding them inlet pipe 15 integrally formed and separated by an integral one-piece partition. These channels take in the FIG. 5 recognizable channels of the at least nearly vertical feed tube 18 on the movable adapter piece 21 and lead them in the inlet pipe 15 on. The channel 16 runs in the direction V to the front sprayer 7, at which the channel 16 ends together with the inlet pipe 15. This end may be bent or bent so that it terminates in the axis of rotation 12 of the front sprayer, such as in the variants according to FIG. 8 is shown.

As described, via the connection end 21, the inlet pipe 15 is separated from or connectable to a supply pipe 18 leading substantially vertically thereto. The feed tube 18 may, as in FIG. 1 run behind a rear wall 22 of the washing container 2 or even be arranged with in this. In this case, the supply tube 18 may form a generally one-piece plastic part with a closed, for example round or rectangular, outline shape, which in turn has separate channels 16, 17 in the interior, sealed in the operating position in the channels 16, 17 of the inlet pipe 15 transfer ,

In order to allow this transition of the channels 16, 17 from the feed tube 18 into the inlet pipe 15, the inlet pipe 15 goes tight from the terminal end 21. For example, the connection end 21 can also be formed in one piece with the axially rear pipe section 19. The connection end 21 itself is in the operating position with the door closed 3 (FIG. FIG. 2 ) is pressed in a transfer area to the feed tube 18, so that also located at the back of the connection end water inlet from the feed tube 18 into the terminal end 21 is sealed. For example, the closed door 3 can provide for the necessary (only slight) contact pressure.

The feed tube 18 itself is supplied with fresh water FW or washing liquor S via a circulating pump 23 assigned to the bottom region of the washing container 2, the circulating pump 23 being fed via a sieve device via water flowing into the bottom. A second pump 25 may be provided for pumping out the wastewater AW no longer needed.

Further, the inlet pipe 15 is attached together with the connection end 21 via, for example, hook 26 or other mechanical connection to the upper dish rack 5 and movable with this. Thus, the inlet pipe 15 can be adjusted in height relative to the feed tube 18 together with the upper washing basket, for example in several stages of 1.5 to 3.5 centimeters each. Here are between the lowest position, in which the upper Spülkorb 5 can be loaded well, for example, with tall glasses, and its highest position, in the lower Spülkorb considerable space for bulky Good is created, two stages of, for example, 2.5 centimeters Height can be added to a Gesamtverstellweg of eg five centimeters. For this is the upright extended Connecting end 21 provided laterally with sliding valves for movement relative to the feed tube 18. Such a height adjustment is shown here only for the upper Spülkorb 5, as it is particularly useful there. The lower washing basket 4 always remains here in its lowest position and is there acted upon by the central spray arm 6.

In addition, the inlet pipe 15 with respect to the feed pipe 18 in the direction of the front V is displaced, so that it can be pulled with the door open 3 with the Spülkorb 5 forward.

As described above, in this case the inlet pipe 15 with the spray devices 7 and 8 or 9 fed by it lies substantially in a plane X, Y, below the washing basket 5, to which it is assigned. In this case, the at least two of the inlet pipe 15 fed sprayers 7 and 8 or 9 are further offset down, in a, preferably common, approximately horizontal plane below the inlet pipe 15. Thus, the top of the inlet pipe 15 directly with hooks 26 or similar connection means be attached to the wash basket 5 to attach.

In FIG. 3 and 4 is - different from FIG. 5 - An embodiment shown in which two sprayers 7, 9 as a succession and below the inlet pipe 15 lying spray arms are formed and are each about the same size, so that they can cover an approximately equal spray area.

In both cases, it is ensured that the front sprayer 7 reaches the collecting container 27 directly with a jet 29, so that a tab located there or the like can be well loosened and introduced into the washing liquor S.

Both spray systems 7 and 8 and 9 are arranged together in the same plane and thereby act on the washing basket 5, to which they are assigned, evenly. In addition, they are vertically displaceable together with the Spülkorb 5, so that in each height position, the admission is guaranteed in constant effectiveness.

It is particularly favorable for a fixed standing Zusatzsprühsystem 8, this in the rear - not in the front region V - provide, as then material can be saved by the short distances there. In addition, then less water in the Tubes, so that due to the smaller dead volume less water FW must be supplied to the device 1 to obtain a round run of the pump. <B> LIST OF REFERENCES: </ b> 1 Dishwasher, 21 Terminal end, 2 rinse tank, 22 Rear wall, 3 Door, 23 circulation pump, 3a Pivot axis 24 screening, 4 wash rack, 25 Pump, 5 wash rack, 26 Hook, 6 spraying, 27 Receptacle 7 spraying, 28 radially outer nozzle 8th spraying, 29 emerging jet, 9 spraying, 10 Roll, S rinsing, 11 Rails, V front 12 Axis of rotation FW Fresh water, 13 Jet, AW Sewage, 14 spray pattern, Z branch, 15 Inlet pipe, A branch pipe 16 Channel in the inlet pipe, 17 Channel in the inlet pipe, 18 feed, 19 axial section, 20 axial section,
