The invention provides a lifting trundle and a household appliance, and the lifting trundle comprises: a housing which is of a hollow structure, and one side of which is provided with an opening; the moving wheel is rotatably arranged in the shell, and a part of structure of the outer peripheral surface of the moving wheel extends out of the shell through the opening; the supporting leg is movably mounted in the shell, and the supporting end of the supporting leg can extend out of the opening; and the driving assembly is connected with the supporting leg and drives the supporting leg to do lifting motion between the first position and the second position. According to the lifting trundle, when the supporting leg is located at the first position, the height of the position, corresponding to the supporting direction, of the supporting end is controlled to be not larger than the height of the lowest position of the moving wheel, so that the moving wheel cannot be borne for a long time and is not prone to being damaged, and the lifting trundle is simple in structure, safe and reliable; in addition, the moving wheels and the supporting legs are arranged in the shell, so that the overall structural strength of the lifting trundle is enhanced, and the service life of the lifting trundle is prolonged.
本发明提供了一种升降脚轮及家用电器,升降脚轮包括:壳体,内部为中空结构,一侧设有开口;移动轮,可转动地设置在壳体内,移动轮外周面的部分结构经开口伸出壳体外;支撑脚,可活动地安装在壳体内,支撑脚的支撑端能够伸出于开口外部;驱动组件,与支撑脚连接,驱动支撑脚在第一位置和第二位置之间升降运动。本发明提供的升降脚轮,支撑脚在第一位置时,通过控制支撑端所在位置对应支撑方向的高度不高于移动轮最低处所在的高度,可使移动轮不会长时间的受承载,不易受到损坏,结构简单且安全可靠;另外,通过将移动轮和支撑脚均设置在壳体内,加强了升降脚轮整体的结构强度,延长了升降脚轮的使用寿命。
