Abstract

The present invention provides a bracket for a height-adjustable washstand capable of allowing the washstand to stably go up and down by providing a cylinder at the bottom of the washstand, and a hydraulic valve capable of controlling a height of the washstand by using hydraulic pressure. The height-adjustable washstand comprises a hydraulic height adjuster, the hydraulic height adjuster comprising: a cylinder vertically provided at the bottom of the washstand or on the floor to allow a washstand to go up and down; a control valve fixed to one side of the washstand to control the operation of the cylinder; a supply pipe for connecting a tap pipe and the control valve; a discharge pipe for connecting the control valve and a drain pipe; and operational pipes for connecting portions above and below an inner piston of the cylinder and the control valve, the height-adjustable washstand further comprising a bracket which comprises: a bedplate for supporting a bottom of the washstand; a guide rail for guiding the bedplate; and a support coupled to the guide rail to support the guide rail. Therefore, according to the present invention, since the washstand can be stably supported and the weight of the washstand can be distributed, the washstand is not rocked and a piston rod is not deformed when the washstand goes up and down, thereby improving the product quality.
