Patent number: 10240279Abstract: The present application relates to a steam device comprising a steam generator (60), at least one steam vent (37) through which steam is emitted from the steam device, a steam path (50) between the steam generator (60) and the at least one steam vent (37). The steam path (50) has a base (53) along which scale is able to pass. The steam device also comprises a noise generator (60) configured to act on steam generated by the steam generator (60) to generate noise. The noise generator (60) is spaced from the base (53) of the steam path (50) so that scale is not obstructed by the noise generator (60).Type: GrantFiled: August 18, 2015Date of Patent: March 26, 2019Assignee: KONINKLIJKE PHILIPS N.V.Inventors: William Wai Lik Wong, Luck Wee Png, Mohankumar Valiyambath Krishnan, Miling Vishwas Date

Patent number: 8752311Abstract: A system and method for using color to indicate a state of a home appliance, such as an iron. The iron has a sole plate and a water tank in fluid communication with the sole plate, a heater for heating the sole plate, a sensor for sensing a temperature of the sole plate, a user interface for setting a desired temperature for the sole plate, and a controller in communication with user interface and the sensor for controlling the heater. An illumination device under the control of the controller is provided to illuminate the water tank, particularly the interior thereof, in a color that is representative of a state of the iron, such as a power condition of the iron and/or a temperature of the sole plate.Type: GrantFiled: December 3, 2012Date of Patent: June 17, 2014Assignee: Sears Brands, L.L.C.Inventors: Ellen Glassman, David Farrage
