Freestanding household dishwashers

The innovation concerns free-standing household dishwashers according to the generic term of claim 1. In the narrower sense, it concerns the introduction and stationary mounting of a concrete weight to increase the stability of the device on the rear machine frame.

Free-standing household appliances with hinged front doors are subject to a so-called "stability test" as per regulations. This involves setting up an unloaded appliance completely freely, i.e. without touching any wall. The horizontally opened front door is loaded with a 25 kg weight at the geometric center. The appliance must then neither tip forwards easily nor fall over. The purpose of this safety test is primarily to protect small children who sit on the open front door from physical injury.

To meet this requirement, a "household appliance, in particular a dishwasher or stove" is known from DE 38 29 381 C2. A concrete counterweight is attached to the housing frame on the back of the appliance. This concrete weight is screwed to the frame struts using a number of holding brackets, guide tabs and clamping brackets that can be bent manually afterwards.

Such a fastening is both material- and assembly-intensive and therefore expensive.

The innovation aims to create an arrangement and fastening device for counterweights in freely installed household dishwashers that is simpler and, above all, more cost-effective than the state of the art.

This object is achieved according to the innovation by the characterizing features of claim 1. Further advantageous embodiments of the innovation can be found in the subclaims.

The advantages that can be achieved with the innovation already arise from the nature of the task, namely a significant reduction in wage and material costs.

An example of the innovation is shown in the drawing and is explained in more detail below.

It shows:

Fig. 1 the concrete counterweight in installation position including the associated fastening leaf spring,

Fig. 2 the fixed concrete counterweight as a side view in section A-A according to Fig. 1.

According to Fig. 1 and 2, an open sheet metal housing 1 with a rear wall 1' is provided in the rear lower frame part of the base of a free-standing dishwasher (not shown in detail). Said sheet metal housing 1 serves to house a counterweight 2 which increases the stability of the device. The counterweight 2 is designed as

rectangular concrete molding with a handle recess 2' on the top. The sheet metal housing 1 has a continuous, vertically upwardly projecting fold 3 with a cut-out 4 on the bottom. A tab 5 with a further recess 6 is punched out on the upper edge of the sheet metal housing 1, angled vertically downwards and bent forwards again at an angle in the form of a longitudinal strip 7. The upper recess 6 and the lower recess 4 are exactly opposite each other in terms of height. The counterweight 2 is placed in the sheet metal housing 1 by pushing it in from the side. The concrete molding, the counterweight 2, lies between the rear wall 1' of the sheet metal housing 1 and the lower fold 3 or the upper tab 5 and is initially secured against falling out. The final positional fixation and transport securing is carried out with the aid of a clamping bracket in the form of a curved and longitudinally beaded leaf spring 8. As shown in Fig. 1, the leaf spring 8 is first placed at an angle on the recess 4 and then inserted between the fold 3 and the counterweight 2, pushed backwards and inserted in the direction of the arrow 9 behind the flap 5 up to the upper recess 6. The recessed grip 2' in the counterweight 2 makes this operation easier to carry out. By then springing back, the leaf spring 8 hooks into the recess 6 with the longitudinal strip 7 and at the same time presses the counterweight 2 captively onto the rear wall 1' of the sheet metal housing 1.

To secure the position of the counterweight 2, only a single inexpensive part in the form of the leaf spring 8 is advantageously required, which can be assembled in a single operation and without any screwing.
