Patent number: 10422521Abstract: The present application relates to apparatus for generating steam. The apparatus comprises an evaporation surface (24), a heater (26) disposed adjacent to the evaporation surface to heat the evaporation surface, a water inlet (19) positioned relative to the evaporation surface so that water is fed onto the evaporation surface from the water inlet and forms a film on the evaporation surface such that the film is evaporated from the evaporation surface, and a scale collection region (23) positioned such that, during use of the apparatus, scale dislodged from the evaporation surface falls away from the evaporation surface into the scale collection region.Type: GrantFiled: July 16, 2014Date of Patent: September 24, 2019Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Hee Keng Chua, Boon Khian Ching, Yong Jiang

Patent number: 10330308Abstract: The present application relates to apparatus for generating steam. It comprises a water inlet, a evaporation surface, and a heater disposed adjacent to the evaporation surface to heat the evaporation surface to a predetermined temperature such that water fed onto the evaporation surface via the water inlet forms a film on the evaporation surface and is evaporated. The apparatus is configured so that water is fed to one or more regions of the evaporation surface, and the temperature of the water fed onto the evaporation surface is lower than the predetermined temperature, so that scale on the or each region of the evaporation surface to which water is fed cools at a different rate at which water on a remainder of the evaporation surface cools. This causes scale on the evaporation surface to break apart and be dislodged from the evaporation surface.Type: GrantFiled: July 14, 2017Date of Patent: June 25, 2019Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Hee Keng Chua, Boon Khian Ching, Yong Jiang

Patent number: 10240278Abstract: A steam iron head (2) employs a soleplate (6) having a fabric contact surface (10), a steam inlet (21) through which steam flows to the steam iron head (2), and one or more steam vents (49). A steam passageway (19) is between the steam inlet (21) and the steam vent(s) (49). A fluid separator (25) is located between the steam passageway (19) and the steam vents (49). The fluid separator (25) is configured to restrict the flow of condensation formed in the steam passageway (19) from passing through the steam vent(s) (49). A soleplate panel (7) forms the fabric contact surface (10) and a base (15, 20) of the steam passageway (19). The soleplate panel (7) is configured to be primarily heated by steam flowing along the steam passageway (19) to the steam vent(s) (49). A steam generator system iron may employ the steam iron head (2).Type: GrantFiled: August 26, 2015Date of Patent: March 26, 2019Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Hee Keng Chua, Boon Khian Ching, Yong Jiang, Boon Teck Tan, Jiecong Tang
