Patent number: 8459754Abstract: A washing machine comprises a casing, a top cover installed on an upper surface of the casing, a door installed at the top cover, through which laundry is accommodated into the casing, and a tub installed in the casing, wherein the door is connected to the top cover by a hinge assembly or a damper assembly provided thereat. The hinge assembly includes a first hinge portion, and a second hinge portion having a torsion spring therein. The damper assembly includes a first damper portion, a second damper portion, and a ring member having a round shape and fitted into an outer circumferential surface of the second damper portion. Accordingly, even when the door has a heavy weight due to its material of a reinforcing glass, the hinge assembly or the damper assembly can endure the weight of the door. This may prevent noise or impact occurring when the door is closed.Type: GrantFiled: March 13, 2009Date of Patent: June 11, 2013Assignee: LG Electronics Inc.Inventors: Cheon-Soo Cho, Hyuk-Soo Lee

Publication number: 20080295546Abstract: In a top-loading type washing machine, a detergent input device is installed at a control panel. Accordingly, a process for opening a lid and putting a user's hand into a cabinet for detergent input is omitted. Furthermore, can be solved a problem occurring when the user inputs a precise amount of detergent to the detergent input device inside the dark cabinet. As a result, the entire process for detergent input is simplified. Furthermore, since the detergent input device is installed at the control panel not inside a top cover, the entire appearance is not degraded even when the top cover is formed of steel.Type: ApplicationFiled: April 8, 2008Publication date: December 4, 2008Inventors: Cheon-Soo Cho, Jong-Kyu Jang, Jin-Soo Kim, Ae-Kyung Chae, Jang-Woo Lee

Publication number: 20080295544Abstract: A laundry machine includes: a casing; a door installed on an upper surface of the casing; a tub installed within the casing; and a buffering unit for buffering an impact when the door is closed. A collision noise or vibration of the door or the casing can be reduced and damage of the washing can be prevented. Also, a hinge assembly for connecting the door to a top cover is provided to stably support the door made of a heavy material such as tempered glass and minimizes an impact or noise when the door is closed.Type: ApplicationFiled: May 27, 2008Publication date: December 4, 2008Inventors: Cheon-Soo Cho, Chang-Woo Son, Jong-Kyu Jang, Jin-Soo Kim, Ae-Kyung Chae, Jang-Woo Lee
