The water purification machine under the cabinet is characterized in that the length of filter elements of the coarse filter system and the fine filter system are increased to be 13-15 inches. The filter elements are lengthened to be greater than 13 inches, so that large flux is achieved, the water producing speed and water yield are increased, and the requirement of household water can be met on the condition of omitting a water storage bucket; the shell is divided into a front cover, a left side board, a right side board, a rear board and a bottom board, the filter systems and the control components are installed on a fixing frame and a U-shaped support in the shell, and the front cover, the left side board, the right side board, the rear board, the bottom board, the fixing frame and the U-shaped support can be conveniently disassembled, so that all the parts are convenient to maintain and replace. The water purification machine under the cabinet is reasonable in structure, large in filter element flux, high in water yield, small in overall size, and convenient to assemble and disassemble.
