Switch position display device for with rotary switches unc, a dashboard equipped household appliances

The innovation relates to a switch position display device For household appliances equipped with rotary switches and a dashboard panel, such as cookers, ovens, washing machines and the like

In known devices of this type, the digits or scales aim to read the power or temperature switched on were previously consistently attached to the circumferential edges of the circular rotary switch handle, while the counter-markings in the form of dots or the like. were provided on the instrument panel of the devices.

In modern household appliances, however, the digits or scales are often in the circular arcs surrounding the rotary switch handles arranged on the dashboard and the switch handle provided with a countermark (point or arrow). These

732956722.11.73

However, the type of numerals and scales arrangement has when the instrument panel is arranged vertically, as is the case, for example with electric cookers is common, the disadvantage that the view of the lower number or scale ranges is obstructed by the rotary switch handles.

The innovation is therefore based on the task of a switch position display device for household appliances equipped with rotary switches and a dashboard create, through which a particularly good readability of the

■■ '♦ respectively switched on power or temperature granted is performing.

The solution to this problem is, according to the present innovation, that the or each of the preferably scaleless, unlabeled Rotary switch handles coupled with a potentiometer or a rotary selector switch and the or each rotary switch handle a digital indicator tube or the like mounted in or behind a recess in the dashboard. assigned is.

j The or each digital number indicator tube is with the her associated potentiometer or rotary selector switch so conductively connected that in the tube that of a certain Switch position corresponding number appears or is switched on.

Further details of the innovation can be found in the following description and the drawing of an exemplary embodiment as well as :: to be found in the subclaims. Show it:

Fig. 3 the front view of the dashboard of an electric cooker with four stollen and an oven.

732956722.11.73

According to Fig. 1, a scaleless, unlabeled rotary switch handle 2 and a rotary potentiometer 3 with power supply 4 are attached to the axis of rotation 1 of a circuit breaker 6. The rotary potentiometer 3 also has
a plug device for connecting a digital digit display tube 5.

Fig. 2 shows an analogous arrangement for the circuit breaker 7 of an oven heating system, in which the numeric display tube 8 the set temperature values appear.

Referring to Fig. 3, four two-digit digital number indicator tubes 5 and one three-digit number indicator tube 8 are in
Rectangular recesses arranged in the dashboard of an electric cooker, namely in a rectangular field lying outside the area of the rotary switch handles 2. The individual indicator tubes are grouped so that
from this the affiliation of the switches 6 assigned to them
to the different hotplates is recognizable.

On the opposite of the number display tubes 5 and 8 On the side of the dashboard ^ a digital timer 11 is installed.

Naturally, the implementation options for the innovation are not exhausted by the exemplary embodiment shown. That's the way it is For example, quite possible, the rotary switch handles 2 despite the arrangement of the digital display tubes 5 and 8 in the usual way Way to provide digits or scales, as indicated in Fig. 1 and 2 in dash-dotted lines. Furthermore, instead of before. Rotary potentiometers 3 and rotary selector switches or the like, as well instead of Digitcil display tubes, there are also others per se known5 display tubes, such as from luminescent diodes composite display tubes can be provided.

Finally, the number indicator tubes can also be used on others Be arranged in the Armafeur screen, for example the corresponding digit display tube above each rotary switch handle 2, even if the illustrated arrangement of the tubes in a particular field is particularly advantageous has proven.
