• the rotary knob is surrounded by a light ring on or next to which washing temperatures as well as washing or spinning programs are indicated.
• the washing temperature or the washing or spinning program is set to which the marking line of the rotary knob points.
• the known light ring is assigned uniformly distributed light-emitting diodes over its entire circumference and spaced apart from one another. According to a known light ring control, all the light-emitting diodes of the light ring are illuminated simultaneously and uniformly in order to illuminate the scale assigned to the light ring.

• a display according to the preamble of patent claim 1 in that it has a speed display for the rotational speed of a rotating working element of the household appliance, including a self-contained strip of luminous elements with a circumference attached along its circumference.
• lighting elements which are controlled in such a way that they flash in a rotating manner at a rotational speed which is proportional to a current rotational speed of the working element and / or that it has a program sequence display, including a lighting element band with lighting elements which are controlled in such a way that starting from a first light element of the light element band with increasing program duration a larger number of light elements is illuminated and at the end of the program all light elements of the light element band are illuminated or that starting from a first light element of the light element band only the light element is illuminated, the position of which within the Luminous element band corresponds to the current duration of the program.
• the speed display according to the invention makes it possible, in a symbolically simple manner, for an operator to determine the rotational speed and the direction of rotation of the working element in each case by means of a
• the program sequence display according to the invention also enables quick information about the temporal progress of the currently running program, because it is easy to grasp optically
• Analog display is presented similar to a bar chart.
• the light element band of the speed indicator is formed by a circular light ring with light elements arranged along its circumference, which flash in a rotating manner in the direction of rotation of the working element.
• the speed display, the program sequence display or other functions can be displayed with the aid of a single light ring.
• each color being different have elements of different colors, each color symbolizing a different display function such as the speed display, the program flow display or a fault display.
• FIG. 1 shows a front view of a section of a front panel of a combination device for washing and spinning laundry with a display according to a preferred exemplary embodiment of the invention

• a rotary switch 2 is rotatably held with a rotary knob 4 protruding from the front panel 1 with a marking 6.
• Rotary switch 2 is used to set washing and spinning programs and washing temperatures, which are indicated on the circumference in addition to a transparent light ring 8 completely surrounding the rotary knob 4.
• the washing temperature or the washing or spinning program to which the mark 6 of the rotary knob 4 points is set in a known manner.
• the light ring 8 forms a light-emitting element band, a plurality of light-emitting diodes 10 having a circumferential spacing from one another being arranged along its circumference on the side of the light ring 8 pointing away from a front viewer.
• the light ring 8 functions as a speed and direction of rotation indicator for the rotation of a laundry drum of the combination device.
• the light-emitting diodes 10 of the light ring 8 are connected to a control device, not shown for reasons of scale, which controls the instantaneous value of a speed sensor
• Speed of the laundry drum receives as a sensor signal.
• the light emitting diodes 10 are so selectively actuated by the control device that they flash in a rotating manner which is proportional to a rotational speed of the laundry drum of the combination device.
• the rotational speed of the flashing of the light-emitting diodes 10 is lower in the “washing” operating state than in the “spinning” operating state.
• the rotating flashing of the light-emitting diodes 10 takes place, as indicated by the arrows in the figure, preferably in the currently existing direction of rotation of the laundry drum.
• Rotating flashing means that one of the individual light-emitting diodes 10 flashes briefly and the light-emitting diode 10, which is adjacent in the clockwise or counterclockwise direction, follows with a time delay. This process then appears to the viewer as if a point of light 12 is moving at a certain rotational speed along the circumference of the light ring 10.
• the speed display for the rotation speed and direction of rotation of the laundry drum is likewise formed by a light ring 14 with light-emitting diodes 16 arranged along its circumference at a circumferential distance from one another.
• the light ring 14 surrounds a porthole 18 of the laundry care device.
• the light ring 14 can also run along the peripheral edge of the porthole 18 itself.
• the control of the light-emitting diodes 16 takes place analogously to the preceding exemplary embodiment in such a way that they flash at a rotational speed which is proportional to a rotational speed of the laundry drum.
• the illuminated ring 14 preferably fulfills a further function in that it also serves as a program sequence display of the program of the combination device that is currently running.
• the LEDs of the light ring 14 are activated one after the other, the number of which corresponds to the current progress of the program. This means that, for example, starting from the uppermost in the illuminated ring 14
• Light-emitting diode 20 clockwise in proportion to the time program run an increasing number of light-emitting diodes 16 are activated, so that when the program has run for example 50%, the light-emitting diodes of an arc 22 of 180 degrees light up, as illustrated in FIG. 3.
• the light emitting diodes 16 of the light ring 14 mentioned are finally activated.
• all the light-emitting diodes 16 of the light ring 14 can also flash.
• the two display functions of the light ring 14, the speed display on the one hand and the program sequence display on the other hand, can alternate automatically or can be programmed optionally.
• lighting elements of different colors can be present for the two functions and the speed display can take place in a color different from the color of the program sequence display. Then, for example, lighting elements 16 of different colors are arranged alternately one behind the other on the lighting ring 14. Use of LEDs 16 as
• Luminous elements are not absolutely necessary, and any other type of selectively controllable luminous elements can also be used, for example also light guides connected to light sources, the free ends of which are accommodated in the light ring 14.
• Combination devices for washing and spinning laundry limited, rather they can be used for any type of household appliances equipped with a rotating work element, for example also for kitchen mixers.
• FIG. 4 shows a further embodiment of a program flow display with a
• Illuminated element band 24 is shown, which preferably has linear elements 26 arranged in a linear and horizontal row, which are controlled in such a way that, like a bar chart, a larger number of illuminating elements is illuminated with increasing program duration, starting from a first illuminating element 28 of the illuminating element band 24 and at the end of the program all lighting elements 26 are illuminated.
• the activated lighting elements 26 thus form a light bar 30, the length of which depends on the previous duration of the program run.
• the program sequence display can contain a digital display 32 for displaying the time of the end of the respective program.
• a time scale 36 from 0 to 80 minutes in time increments of 20 minutes is plotted parallel to the luminous element band 34 of the program sequence display in order to be able to assign a specific program runtime to the light bar 38 formed from luminous elements 37.
• the lighting element 44 is activated in each case, the position of which in the row of lighting elements 41 corresponds to the currently past program duration. This results in a light spot 44 moving from left to right, the program sequence having progressed the further the light spot 44 is located to the right.
• the beginning and end of the lighting element band 42 can additionally be marked by permanently activated lighting elements 40, 46.
• the form of the program sequence display and / or the speed display is not limited to circular or linear light element strips 8, 14, 24, 34, 42; rather, any shapes such as rectangles or ellipses can be used for this purpose.
