Title: Stand-type Steam Iron
Inventor: PARK JUN BEOM
IPC: D06F73/00
Filed: 2020-07-03
Abstract: The present invention relates to a stand-up steam iron. An inventor of the present invention has always wondered if there is any way to improve a steam iron while watching his/her mother feel pain in her arm while ironing. Meanwhile, he/she saw a mannequin being used for clothes display in a clothing store and thought that it would be good to combine the mannequin with the steam iron. The stand-up steam iron of the present invention is connected to a conventional steam iron used at home, and allows wrinkles of the clothes to be flattened just by hanging the clothes. Therefore, a user can iron more conveniently than when using the conventional steam iron. In addition, when there is no need to iron, the stand-up steam iron can be used as a hanger, and since the stand-up steam iron can be disassembled into parts, the stand-up steam iron has an advantage of simplifying storage and cleaning.

Abstract: The present invention relates to a lint remover which has an improved structure to facilitate discharge of lint and adjust the angle of a handle, thereby increasing user convenience. According to the present invention, the lint remover comprises: a head unit removing lint by rotating blades; a handle provided at one end of the head unit to be gripped by a user; and a dust collection unit collecting and storing the lint removed from the head unit. The head unit includes, in a case, an operation unit, a blade, and a porous cap to remove lint while protecting the blade. The dust collection unit forms a partition wall corresponding to the outer circumference of the blade formed at the upper end of the case to include a first receiving space primarily collecting and temporarily storing the lint removed by the blade and a second receiving space formed along the circumference of the first receiving space to secondarily collect the lint discharged from the first receiving space. A plurality of outlets are formed radially in the partition wall to discharge the lint and an annular dust collection cover is installed on the outer periphery of the partition wall to cover the second receiving space. Accordingly, since the lint removed by the blade is collected into the first receiving space and then collected into the second receiving space through the outlet, the lint is discharged without blocking a path through which the lint is discharged, and thus the lint remaining on the operation unit is minimized. In addition, the lint is distributed in a radial direction while the angle of the head unit and handle is adjusted, thereby providing an effect of efficiently collecting and discharging lint when the lint remover is used.
