Patent number: 10941517Abstract: The present application relates to a hand-held garment steamer (1) comprising a steam generating chamber (5) having a surface (9) and a heater (10) to heat the surface (9) such that water fed onto the surface (9) is converted into steam. The hand-held garment steamer (1) further comprises a scale collection chamber (14) having an opening (25). The surface (9) and opening (25) are positioned relative to each other and configured so that when the garment steamer (1) is in a first orientation (A) in which the surface (9) extends downwardly away from the opening (25), water fed onto the surface (9) flows away from the opening (25) to be evaporated from the surface (9). When the garment steamer (1) is in a second orientation (B) in which the surface (9) extends downwardly towards the opening (25), scale dislodged from the surface (9) falls into the scale collection chamber (14) through the opening (25).Type: GrantFiled: December 9, 2016Date of Patent: March 9, 2021Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Chee Keong Ong, Zhifeng Xu
