Patent number: 11089658Abstract: The present invention relates to a wet planar heating element and a method manufacturing the same. The element including: a planar heating unit including an upper waterproof film layer, a lower waterproof film layer, a planar heating layer, and an electrode layer; an external waterproof film layer; and a non-woven fabric layer. According to the present invention, it is possible to minimize leakage current due to pores of a non-woven fabric substrate and a low dielectric constant of air in air pockets, thereby solving problems that an earth leakage circuit breaker operates. Accordingly, wet construction can be performed, power consumption can be reduced, and an electrical fire risk can be remarkably lowered. In addition, it is possible to improve flexibility of the planar heating element, whereby the use of the planar heating element can be expanded and the efficiency of the construction work can be increased.Type: GrantFiled: May 19, 2017Date of Patent: August 10, 2021Assignee: NDT ENGINEERING & AEROSPACE CO., LTD.Inventors: Ki-Hyun Lim, Chi-Woo Noh

Patent number: 5839300Abstract: A pulsator for a washing machine generates a vortex-type water current in a washing tub in order to wash washing articles. In the pulsator of a washing machine, a base plate is fixed to a shaft of the washing machine to be rotated according to a rotation of the shaft. A plurality of stirring blades are downwardly slanted from the center of the base plate to an outer periphery thereof in a sector form on a bottom surface of the base plate. The plurality of stirring blades define at least one concave collecting basing between adjacent stirring blades on the bottom surface of the base plate. The pulsator for a washing machine generates a vortex-type water current in a washing tub and evenly transmits a friction force generated by a washing water current to the washing articles in a state that a current of the washing water is not uniform inside the washing tub thereby minimizing the twist of washing articles and increasing washing efficiency.Type: GrantFiled: April 29, 1997Date of Patent: November 24, 1998Assignee: Daewoo Electronics Co., Ltd.Inventors: Chong-Man Yoon, Ki-Hyun Lim, Jong-Chil Lee
