Title: the barrel washing machine in which the foot rest runs
Inventor: LEE YOO NA
IPC: D06F39/12
Filed: 2021-06-22
Abstract: When a top-loading washing machine is used, the barrel has a depth such that people short in stature and women use footholds or foot rests to eject laundry. To solve this inconvenience, the present invention allows a foot rest to be built in a washing machine without a purchase of a foot rest. The present invention is conceived based on the auxiliary door of a refrigerator and the dust filtering net of a drum washing machine. A foot rest is added at the lower end portion of the top-loading washing machine, corresponding to the place in which the dust collecting net of the drum washing machine is inserted. When the corresponding portion is pushed by a foot, the portion protrudes as the auxiliary door of a refrigerator protrudes when pushed, before the built-in foot rest is changed into a horizontal shape such that the foot rest may be used. In addition, the foot rest is built therein, thereby preventing an additional space from being occupied. The foot rest is built in the left lower end portion of the washing machine. The present invention is provided to allow the user to conveniently eject laundry after the washing is completed. To use the present invention, first, push the left lower end portion with the foot in the same way one uses the auxiliary door of a refrigerator. Next, the built-in foot rest is ejected in an L-shape before being shaped in a horizontal I-shape. When the user steps thereon, the present invention can be used without a purchase of an additional foot rest, thereby easily ejecting laundry. In addition, when not in use, the foot rest may be pushed by the foot according to the same principle to be placed to the original position, thereby preventing the occupation of space. To this end, the top-loading washing machine comprises: a detection sensor; a screw; and a foot rest.
