The present invention relates to a household appliance comprising a knob.

In household appliances, knobs providing the operation of the household appliance or the adjustment of programs parameters are widely used. In terms of ease of utilization and decorative appearance, the peripheries of the knobs are illuminated. In order to illuminate the peripheries of the knobs, generally light emitting diode (LED) light bulbs are placed into the housing whereto the knob is mounted. Since the LED light bulbs are required to be disposed to the limited area behind the knob, problems occur in the production during the assembly and the labor hours spent for intervention in case of a malfunction increase.

In the state of the art United States Patent No. US6348772, a knob is described comprising LED light bulbs. LED light bulbs are positioned behind the knob.

In the state of the art International Patent Application No. WO2010089556, a household appliance is described, that comprises a knob the outer periphery of which is illuminated by means of the light sources positioned in the housing. EP 1 995 751 A2 discloses a household appliance comprising an opening arranged on a body; a cylindrical knob, which is moved by being rotated and pushed, and at least one light source that emits light into the housing, a transparent illumination aperture extending along the line where the front and lateral surfaces of the knob intersect; and a carrier whereon the light source is placed so as to illuminate the illumination aperture when the knob is placed into the housing.

The aim of the present invention is the realization of a household appliance comprising a knob of which the outer periphery is illuminated and ease of assembly is provided.

The household appliance realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof comprises a housing placed into an opening on a body and a knob mounted into the housing. Light sources are placed at the rear side of the knob. The periphery of the knob is illuminated by means of an illumination aperture that transmits the light coming from the light source. The light sources are positioned on a carrier. The periphery of the knob is illuminated by means of the carrier and the illumination aperture.

In an embodiment of the present invention, the carrier is ring-shaped. Thus, the carrier can be easily placed into the housing.

In another embodiment of the present invention, the household appliance comprises two upright members that limit the movement of the knob while the knob is rotated right and left and a C-shaped carrier placed between the upright members. The C-shaped carrier can be easily placed between the upright members.
