Publication number: 20130269224Abstract: The present invention relates to an apparatus for generating steam comprising a water heating chamber in which water is heated to generate steam. The apparatus also includes a cavity having an inlet communicating with the water heating chamber so that water in the water heating chamber is received in the cavity and a sealable outlet. The cavity is configured to limit the flow of convection currents in the water received in the cavity so that scales and/or solid particles suspended in the water accumulate in the cavity. Alternatively, a guide member is disposed at the inlet to the cavity which is configured to guide scales and/or solid particles suspended in the water into the cavity.Type: ApplicationFiled: December 30, 2011Publication date: October 17, 2013Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Milind Vishwas Date, Mohankumar ValIyambath Krishnan

Patent number: 7721474Abstract: A steam iron assembly (1) comprises a steam iron (10), a steam generator (20) and a water reservoir (30). Furthermore, a pump (40) is provided for pumping water from the water reservoir (30) to the steam generator (20). Inside the steam generator (20), the water is heated to steam. The generated steam is conducted through the steam iron (10) to an item to be ironed. The steam iron (10) comprises a soleplate (11) having a contacting surface (12) for contacting items to be ironed. A temperature of the soleplate (11) is kept at a relatively low level of for example 110° C. throughout an entire steam ironing process, whereas variations of an ironing temperature are obtained on the basis of variations of a temperature of the supplied steam. As a result of these factors, the risk of scorching of the items to be ironed is reduced.Type: GrantFiled: June 15, 2005Date of Patent: May 25, 2010Assignee: Koninklijke Philips Electronics N.V.Inventors: Yong Jiang, Boon Khian Ching, Mohankumar Valiyambath Krishnan, Peter Jeeninga

Publication number: 20100043260Abstract: An ironing board (1) comprises a fan (20) for generating an airflow and a controlling unit (40) for controlling a mode in which the fan (20) is driven during operation of the ironing board (1). When there is a need for obtaining an airflow through an item to be ironed, the controlling unit (40) puts the fan (20) to a mode in which it is driven at a normal operating speed. However, when there is no such need, the controlling unit (40) puts the fan (20) to a mode in which it is driven at a speed which is lower than a normal operating speed. In this way, it is achieved that the fan (20) is continuously driven during operation of the ironing board (1), also in case an ironing process performed with the help of the ironing board (1) does not require an operation of the fan (20). As an advantageous result, condensation of steam inside the ironing board (1) is prevented.Type: ApplicationFiled: July 4, 2006Publication date: February 25, 2010Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Chandra Mohan Janakiraman, Mohankumar Valiyambath Krishnan, Mong Hua Tan, Swee Loon Michael Tang, Choon Hwee Tan, Kok Wah Ma, Derrick Wai Thong Loke

Patent number: 7607246Abstract: A steam ironing device (1) comprises a steam generator (20) for heating water to steam, a steam outlet (25) for letting out a burst of steam (27) from the steam generator (20), a device (30) for supplying water to the steam generator (20), a hose (40) connecting the water supplying device (30) to the steam generator (20), and a controller (50) which is adapted to operating the water supplying device (30) during a period of time in a situation in which there is hardly any need or no need at all of a supply of steam in an ironing process, while keeping the steam outlet (25) closed. In this way, a reserve amount of steam is generated, which is stored in an internal space (21) of the steam generator (20), and, as the occasion arises, inside at least a portion of the hose (40). When a burst of steam (27) is required, the reserve amount of steam is released through the steam outlet (25).Type: GrantFiled: July 18, 2006Date of Patent: October 27, 2009Assignee: Koninklijke Philips Electronics N.V.Inventors: Mohankumar Valiyambath Krishnan, Zhenhua Yu

Patent number: 7603801Abstract: A garment de-wrinkling device (1) comprises an enclosure (10) for moistening garments (20). An ironing board (40) and an adjacent standby area (41), which are both permeable to steam, are arranged on top of the enclosure (10). During operation of the device (1), the ironing board (40) and a steam iron (30) are used to iron garments (20) which have first been moistened inside the enclosure (10). In the process, steam released by the iron (30) penetrates the garments (20) and enters the enclosure (10) through the ironing board (40). In this way, both the garments (20) on the ironing board (40) and those inside the enclosure (10) are treated by means of steam that is released by the iron (30), and steam is used in an efficient manner. A pressed look is obtained in that the garments (20) are subjected to a moistening process and a subsequent steam ironing process.Type: GrantFiled: November 4, 2004Date of Patent: October 20, 2009Assignee: Koninklijke Philips Electronics N.V.Inventors: Yong Jiang, Mohankumar Valiyambath Krishnan, Boon Khian Ching, Tao Guo, Vidya Sagar Gannamani

Patent number: 7516567Abstract: A steam iron (1) comprises a steam conditioning device (30) having two vortex chambers (31, 32). Inside the vortex chambers (31, 32), directing means such as a conduit for directing a steam flow toward outlets (33) of the steam conditioning device (30) are arranged. Further, inside the vortex chambers (31, 32), vortex generating means are arranged, which are arranged along a path followed by the steam flow, and which are adapted to creating local pressure differences in the steam flow in order to obtain local vortices in the steam flow. By means of the vortices, during operation of the steam conditioning device (30), water drops which are present in the steam flow are broken down to a smaller particle size. In this way, the steam conditioning device (30) is capable of producing mist-steam or dry steam.Type: GrantFiled: March 21, 2005Date of Patent: April 14, 2009Assignee: Koninklijke Philips Electronics N.V.Inventors: Yong Jiang, Mohankumar Valiyambath Krishnan, Mun Thoh Ma
