The invention provides a multifunctional valve. The multifunctional valve comprises a temperature-controlled valve element assembly, a switch and switching valve element assembly and a transmission mechanism. The temperature-controlled valve element assembly comprises a first shell and a temperature-controlled operation assembly, the first shell is provided with a cold water inlet, a hot water inlet and a mixed water outlet, and the temperature-controlled operation assembly is used for adjusting the temperature of water flow of the mixed water outlet, and comprises a temperature-adjusting rotating rod and a temperature-adjusting knob; the switch and switching valve element assembly comprises a second shell, a pressing switch operation assembly and a rotation switching operation assembly, amixed water inlet, a first mixed water outlet and a second mixed water outlet are formed in the second shell, and the mixed water inlet communicates with the mixed water outlets; the rotation switching operation assembly is used for selectively opening the first mixed water outlet or the second mixed water outlet; the temperature-adjusting knob is rotatably mounted on the rotation switching operation assembly; the pressing switch operation assembly is used for selectively opening or closing the mixed water inlet; and the transmission mechanism is arranged between the temperature-adjusting knob and the temperature-adjusting rotating rod and is used for adjusting through-flow sectional area of the cold water inlet and/or the hot water inlet.
