Patent number: 9719675Abstract: The present application relates to apparatus for generating steam. It comprises a water inlet (19), a evaporation surface (24), and a heater (26) disposed adjacent to the evaporation surface (24) to heat the evaporation surface (24) to a predetermined temperature such that water fed onto the evaporation surface (24) via the water inlet (19) forms a film on the evaporation surface (24) and is evaporated. The apparatus is configured so that water is fed to one or more regions of the evaporation surface (24), and the temperature of the water fed onto the evaporation surface (24) is lower than the predetermined temperature, so that scale on the or each region of the evaporation surface (24) to which water is fed cools at a different rate at which water on a remainder of the evaporation surface (24) cools. This causes scale on the evaporation surface (24) to break apart and be dislodged from the evaporation surface (24).Type: GrantFiled: July 16, 2014Date of Patent: August 1, 2017Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Hee Keng Chua, Boon Khian Ching, Yong Jiang

Publication number: 20170184302Abstract: The present application relates to a steamer head comprising a treating face (13A, 33A) from which steam is expelled, and a steam generating surface (14A, 34A) onto which a liquid is provided to be converted into steam. The treating face (13A, 33A) is in thermal conductive communication with the steam generating surface (14A, 34A). The steam generating surface (14A, 34A) is at an angle to the treating face (13A, 33A) such that when the treating face (13A, 33A) is orientated vertically, the liquid is able to descend onto and flow along the steam generating surface (14A, 34A) to be converted into steam.Type: ApplicationFiled: May 18, 2015Publication date: June 29, 2017Inventors: HEE KENG CHUA, BOON KHIAN CHING, YONG JIANG

Publication number: 20170089003Abstract: The invention relates to a steaming device component (4, 7, 25) comprising a passageway (16, 23, 33) having an inner surface (17, 24, 34) along which steam may flow. At least a section of the inner surface (17, 24, 34) is formed by a foam material (19, 35) having a low thermal conductivity such that the foam material (19, 35) reduces the rate of condensation on the inner surface (17, 24, 34). Since the foam material requires less heat energy to attain the same temperature as the steam, the foam material heats up quickly reducing the time in which condensation can take place on the inner surface of the steam passageway.Type: ApplicationFiled: May 5, 2015Publication date: March 30, 2017Inventors: HEE KENG CHUA, BOON TECK TAN, YUQI WANG

Patent number: 8863061Abstract: Providing ASIC equivalents of FPGAs is facilitated and made more efficient and economical by using an ASIC architecture including a plurality of so-called hybrid logic elements (“HLEs”), each of which can provide a portion of the full functionality of an FPGA logic element (“LE”). The functionality of each FPGA LE implementing a user's logic design can be mapped to one or more HLEs without re-synthesis of the user's logic. Only as many HLEs as are necessary are used to perform the functions of each LE. The one-for-one equivalence between each LE and either (1) one HLE or (2) a group of HLEs facilitates mapping (without re-synthesis) in either direction between FPGA and ASIC designs.Type: GrantFiled: July 31, 2013Date of Patent: October 14, 2014Assignee: Altera CorporationInventors: Kar Keng Chua, Sammy Cheung, Hee Kong Phoon, Kim Pin Tan, Wei Lian Goay
