Description

dishwasher

The invention relates to a dishwasher, in particular a dishwasher for the household sector having the features of the preamble of claim 1.

The size of the dishwasher is an essential criterion in the planning and construction of modern kitchens and kitchen islands, but also kitchen solutions with passages. In the latter, the filling of the dishwasher is an obstacle, since the plates must be first transported to the kitchen after completion of the meal in order to fill the dishwasher there. For older kitchen owners, an ergonomic obstacle is added, since dishwashers, because of their size, usually sit on the floor and you always have to bend down to fill a conventional dishwasher.

These problems have recently been addressed by dishwasher trays, but even with a drawer solution, the poor accessibility has remained. Furthermore, in such a solution, the supply of water and electricity and the disposal of the cleaning liquor via a cable management system, with hoses and cables were brittle after a period of use by excessive kinking.

It is therefore an object of the invention to provide a dishwasher, which is flexibly adaptable to the external conditions and provides easy accessibility to fill the dishwasher with dishes or the like.

The invention solves this problem by a dishwasher with the features of claim 1.

The dishwasher according to the invention thereby has at least a body, with a washing compartment, a water supply and a waste water discharge. The body can be integrated among other things in a kitchen cabinet or in a kitchen island. The dishwasher in this case has an extract element, which of at least two sides of the body of the dishwasher or the furniture itself is herausführbar.

The kitchen cabinet can for example be part of a partition wall between a preparation room of the kitchen and a dining room, the dishwasher from the side of the kitchen and the dining room can be filled or emptied. Thus, there is a slight infestation of the dishwasher on the part of the dining room, e- as well as an easy emptying of the dishwasher on the part of the preparation room, storage space or the kitchen.

The dishwasher can be dimensioned such that no bending over to fill the dishwasher is required. In this case, an extract element with a cistern, for example, be designed as dish drawer and be pulled out by pulling or pivoting or other options for at least two sides of the body of the dishwasher.

Thus, in addition to the ergonomic and organizational advantages, the dishwashing machine according to the invention creates a connection between two rooms, such as a dining room and a preparation or storage room.

Alternatively, a dish rack, and not the entire cistern, after opening of various flaps (top and / or side flaps) can be led out of the body to two sides.

It is advantageous if the extract element in two opposite

Pages from the body is pulled out, so that analogous to a drawer in the present case, the leadership can be done for example by fittings.

As an alternative to the variant of the extraction of the complete cistern, in an advantageous embodiment, only a crockery basket can be pulled out on both sides, wherein the body is provided with flaps, which also serve as a drip pad when removing the crockery basket. It is particularly advantageous if a rotary joint is coupled to the drainage element on the pull-out element, which is adjoined by a telescopic arm, which in turn is formed with a further joint in the form of a pivoting arm. During relative movement of the pull-out element on one side or the other side by at least partial axial extraction of the pullout element from the body of the telescoped arm always a drip-proof connection of the pullout element with a drain pipe forth, Furthermore, a tube for circulating the rinsing liquor is provided.

The wastewater can be conducted after flushing from the cistern so advantageous in the interior of the telescopic arm to a drain pipe. In this case, the difference in spacing between the extract element and the drainpipe does not matter, since these distances are bridged by the telescoping of the pivot arm. Thus, a buckling of the drain pipe is advantageously prevented and the permanent and undisturbed drainage of the rinsing liquor after the

Rinsing process ensured.

It is furthermore advantageous if both the water supply line and the power supply line of the dishwasher are guided so flexibly on the telescopic arm, in particular by a loop-shaped guide, that the pull-out element can be completely pulled out of the carcass, but at the same time when inserting the pull-out element into the housing Corpus it does not come to a kink of the power supply or the water supply.

At least two sides of the body are advantageously two pivotable

Flaps provided, can be filled or emptied by the dishwasher respectively. After opening the respective flap, for example, a dish basket can be extended. At the same time the second flap is locked, so that a simultaneous opening of several flaps can be prevented.

Moreover, it is advantageous if the front panels of the extension element can be coupled on the extension side and decoupled on the opposite side, so that on one side of the furniture part always the appearance of a closed drawer is maintained, whereas on the other side of the furniture partly advantageously the extraction of the extract element, for example, by a handle which is attached to the respective front panel, is facilitated.

The connection between the extension element and the front panel can be made particularly advantageous by coupling the front panel in a mechanical, magnetic or electromagnetic manner, wherein a sensor can trigger a touch of a coupling of the corresponding pullout element with the front door, with simultaneous decoupling of the front panel of the carcass. The same effect can alternatively be achieved by a mechanical device, actuation of a lever or the like.

It is particularly advantageous if the front flaps are attached liquid-tight on the body in order to prevent leakage of the rinsing liquor.

In an advantageous embodiment variant, a sensor system can set in motion a mechanical or electrical drive for extending the pull-out element inside the carcass.

Furthermore, it is advantageous if the dishwasher has a device for receiving and attaching cleaning rod. This allows for the lighter

Operation of the machine by cleaning bar e.g. be used as compressed tablets or as a standard pack next to the control panel, avoiding spilling or improper dosing of cleaning salt. Thus, dosing and replenishment of cleaning chemicals can be done in a clean and environmentally friendly manner without getting in contact with chemicals.

An embodiment of the invention is explained in more detail with reference to the accompanying drawings:

Fig. 8: a section through a body with dishwasher

1 shows a dishwasher with a body 2 and a Auszugsele- element 1, which is pulled out in the direction A from the furniture body 2.

With the extract element 1, a front panel 3 is connected by means not shown coupling elements. A handle 4 makes it possible to manually pull the pull-out element 1 out of the furniture carcass 2. The pull-out element 1 furthermore has a flushing space 8 for receiving items to be washed, such as e.g. Dishes,

Cutlery and the like. The washing compartment 8 has, for example, the dimensions of a sink with a total volume of between 30 to 300 liters. At the bottom of the washing compartment 8, a spray arm 6 is mounted in a recess 7. This flushing arm 6 serves to circulate the rinsing water in the dishwasher. Between the washing compartment 8 and the front panel 1, a web is provided with two receptacles 5 for detergent, in particular cleaning tabs. The storage rack or dish rack is not shown for reasons of clarity.

FIG. 2 shows the dishwasher in which, in comparison to FIG. 1, the pull-out element 1 is pulled out of the furniture body 2 in the B direction. In this case, now the front panel 3 'is coupled to the pullout element 1. The front panel 3 is decoupled from the pullout element 1. Thus, a two-sided extensibility of the pull-out element 1 in the A and B direction from the furniture body 2 is ensured. Other components such as the receptacles 5 for cleaning

Tabs, the spray arm 6 with the corresponding recess 7 and the handle 4 are identical to Figure 1, since the pullout element 1 only, as already mentioned, was pulled out in the direction B. The front panels 3, 3 'are releasably coupled to the pullout element. Thus, the one front panel, on which the direct pulling force of the user interacts with the pull-out element, is coupled. At the same time, however, it is released from the body 2. The opposite front panel is coupled to the body 2 but detached from the pullout element.

The coupling of the two front panels 3, 3 'with the body 2 takes place in such a way that the front panels lie close to the body, so that no liquid can escape during the washing process. The seal can be arranged as a frame seal, which covers at least the Spülraumumfang in the body 20 or the pull-out element 10.

Figure 3 A is a detailed view of a pullout element 1, which protrudes from the furniture body 2. In particular, the filling of the receptacle 5 is shown with a cleaning tab 10. This cleaning tab 10 can, as shown in Figure 3b, placed on a mandrel 9 and anchored. FIG. 4 shows the operation of the dishwasher by an operator 25. A control panel 24 is arranged ergonomically favorably for the operator 25. The operation can take place in the direction A and in the direction B of the pull-out element 1. All controls are redundant near the front panel 3 and 3 ^! executed.

FIG. 5 shows the water supply and disposal of the dishwasher. In this case, rinse water is passed from a water connection through a water pipe into the interior of the pullout element 1. A waste water discharge pipe 12 provides for the discharge of the waste water from the interior of the pull-out element. 1

For this purpose, a drain pump 16, which prevents stagnation of the wastewater and thus resulting odor nuisance. The drain pump 16 may also be arranged with in the extract element 1. The drainage pipe 16 is adjoined by the wastewater pipe 15, which directs the wastewater into the drain. The dishwasher and the drain pump 16 are connected by an electrical connection 14.

FIGS. 6 to 8 show the schematic representations of the device for discharging the rinsing liquor on the pull-out element 1. The device comprises for deriving the rinsing fleet a hinge 17 which is fixed to the underside of the pullout element 1, and an adjoining wastewater discharge, which is formed in the present example as a pivot arm 18. The swivel arm 18 comprises a telescopic arm 19, which is rather firmly connected to the swivel joint 17 and leads away from the swivel joint 17 perpendicular to the axis of rotation. The telescopic arm has at least two telescopic members. The telescopic arm 19 opens into a joint 20 which is connected to a rotatably mounted waste water discharge pipe 12. In the intermediate space of the plugged-individual telescopic members of the telescopic arm 19 is in each case a seal 21. The hinge 17 is sealed to the pullout element 1 via a rotatable seal, such as a lip seal.

The wastewater is passed through the pivot 17, the telescopic arm and the joint in the rotatable waste water discharge pipe 12 and forwarded via the drain pump 16 and the drain pipe 15 into the drain. The individual joints are provided with seals.

In the figure 8 pullout guides 23 and an underlying drawer 22 are shown. This shows that the storage space in the furniture carcass 2 can be usefully used with conventional storage solutions due to the advantageous device for draining the rinsing liquor and the corresponding supply of energy and water. There is no unused space.

As an alternative to the listed embodiment, the pull-out element 1 instead of a drawer can also be designed in the form of a dish rack. This is accessible by pivoting outer flaps, instead of front panels 3, 3 ', and can be pulled out or swung out. Again, the two-sided Herausführbarkeit the extract element is guaranteed.

The pull-out element 1 can be brought out of the body 2 both by a linear method and by angled method. Another possibility of two or more sided leading out of the extract element 1 from the body 2 can be done via a pivot mechanism LIST OF REFERENCE NUMBERS
