Abstract
An operating element for a domestic appliance includes a main body which is made of a material comprised of plastic and a filler admixed to the plastic. The filler has a thermal conductivity which is higher than a thermal conductivity of the plastic. The filler can be present in particle form, e.g. as spheres, grains, fibers or as powder.
Claims8
An operating element for a domestic appliance, said operating element comprising a main body made of a material comprised of plastic and a filler admixed to the plastic, said filler having a thermal conductivity which is higher than a thermal conductivity of the plastic, said material of the main body having a thermal conductivity of 1 to 20 W/mK.
A domestic appliance, comprising at least one operating element including a main body made of a material comprised of plastic and a filler admixed to the plastic, said filler having a thermal conductivity which is higher than a thermal conductivity of the plastic, wherein the material of the main body has a thermal conductivity of 1 to 20 W/mK.
A domestic appliance, comprising:
- a heat conducting member;
- and
- at least one operating element to control the heat conducting member, the operating element comprising a main body configured to be directly touched by a user to apply a force to actuate the operating element, the main body comprising a material with a plastic and a filler admixed to the plastic, said filler having a thermal conductivity which is higher than a thermal conductivity of the plastic thereby providing a cool metal sensation to the skin of the user when the main body is touched by the user, wherein the material of the main body has a thermal conductivity of 1 to 20 W/mK.
An operating element for a domestic appliance, said operating element comprising a main body made of a material comprised of plastic and a filler admixed to the plastic, said filler having a thermal conductivity which is higher than a thermal conductivity of the plastic, wherein the filler is a metal filler, the metal filler includes powdered copper, aluminum or stainless steel, and the metal filler is present in the material of the main body at a proportion by volume which is less than 70%.
