Switch device, household appliance having such a switch device, and method for displaying the power state of a household appliance

Abstract

The invention relates to a switch device, a household appliance having such a switch device, and a method for displaying the power state of the household appliance. In order to refine a switch device for a household appliance, comprising: at least one switch shaft (10) configured for regulating at least one power of the household appliance, said switch shaft extending from the outside of the household appliance into an interior of the household appliance, at least one power range marking (30; 30'; 30'') visible on the outside of the household appliance and disposed at least in some regions around the switch shaft (10), said marking representing the value range of the power that can be regulated by means of the switch shaft (10), and at least one illuminating unit (61, 62, 63, 64, 65, 66) disposed in the interior of the household appliance for illuminating the power range marking (30; 30'; 30''), such that the power of the household appliance can be regulated more precisely and easily, it is proposed to dispose at least one indicator (40) for displaying the power state of the household appliance set by way of varying the position or orientation of the switch shaft (10) such on the switch shaft (10) that the indicator (40) follows any change in position or orientation of the switch shaft (10), and that the indicator (40) is located in each case in the beam path of the light emitted by the illuminating unit (61, 62, 63, 64, 65, 66) for the region (50) of the power range marking (30; 30'; 30'') associated with the current position or orientation of the shift shaft (10).

Description

technical field [0001] The invention relates to a switchgear according to the preamble of claim 1 and to a household appliance, in particular a cooker, oven or cooker, preferably a gas cooker, gas oven or gas cooker, having such a switchgear. The combination of cooking utensils and ovens is represented by the concept cooker below. The concept cooker includes, inter alia, cooking modules, hobs and cooktops. [0002] The invention also relates to a method according to the preamble of claim 18 . Background technique [0003] The power status of the range is usually indicated by the position of the rotary switch or knob used to operate the cooker or oven. In this case, as disclosed in DE 1 274 307 A, DE 1 846 780 U and DE 2204 557 A, the position of the rotary switch can be displayed digitally in the display field. In these known rotary switches, a disc with numbers is arranged on the rotary switch control shaft arranged in the cooker. Depending on the position of the rotary...
