1. A household appliance, comprising:
an information light device including a light source and a light guide,
wherein the light source is arranged to generate light that travels through the light guide and is distributed from the light guide,
wherein the light guide is arranged to indicate an operating status of the household appliance,
wherein the light guide is an elongated member extending along a width of the household appliance such that the light travels through the light guide and along the width of the household appliance, and
wherein the light guide is disposed at a lower portion of the household appliance such that when the light is distributed from the light guide the light arranged to appear as a stripe of light on a floor adjacent the household appliance.
2. The household appliance according to claim 1 , wherein the light guide is a wave guide.
3. The household appliance according to claim 1 , wherein the light source is disposed on at least on one end of the light guide.
4. The household appliance according to claim 3 , wherein the light guide is structured to allow at least part of the light to exit the light guide in a direction that is perpendicular to the light guide.
5. The household appliance according to claim 4 , further comprising a base cover, and wherein the light guide is disposed on the base cover.
6. The household appliance according to claim 5 , wherein the base cover is a toe panel.
7. The household appliance according to claim 6 , further comprising a door seal plugged onto the toe panel and structured to seal a space between a door of the household appliance and the toe panel.
8. The household appliance according to claim 7 , wherein the door seal is formed from a transparent Polyvinyl chloride (PVC) material that allows the light exiting the light guide to travel from the light guide, through the door seal, and onto the floor where the household appliance is disposed.
9. The household appliance according to claim 3 , wherein the light source is a light-emitting diode (LED).
10. The household appliance according to claim 4 , further comprising one or more lenses structured to focus the light that exits the light guide.
11. The household appliance according to claim 1 , further comprising an outer door, and wherein the light guide is disposed on an inside at a bottom area of the outer door.
12. The household appliance according to claim 1 , wherein a length of the light guide is about equal to a width of the household appliance.
13. A method for indicating an operating status of a household appliance, the method comprising the steps of:
generating light by a light source through an elongate light guide such that the light travels through the light guide and along an edge of the household appliance,
distributing the light from the light guide in at least a direction that is perpendicular to the light guide such that the light is arranged to appear as a stripe of light on a floor adjacent the household appliance; and
indicating an operational status of the household appliance with the light arranged to appear as a stripe of light on the floor.
14. The method according to claim 13 , further comprising focusing the light as the light exits the light guide.
15. The method according to claim 13 , further comprising focusing the light by one or more lenses, wherein a length of the strip of light is about equal to a width of the household appliance.
16. The method according to claim 13 , wherein the light source is a light-emitting diode (LED).
17. The method according to claim 13 , wherein the light guide is a wave guide.
18. The method according to claim according to claim 13 , wherein the light exiting the light guide in at least a direction that is perpendicular to the light guide travels through a door seal of the household appliance, and onto the floor where the household appliance is disposed.
19. The method according to claim 18 , wherein the door seal is formed from a transparent Polyvinyl chloride (PVC) material.
20. The method according to claim 13 , wherein the light guide is disposed at a lower portion of the household appliance and extends along a width of the household appliance, and a length of the light guide is about equal to a width of the household appliance.
