Abstract

The invention provides a water valve and a washing machine provided with the same. The water valve comprises a valve seat, a valve core seat, a valve core, a rotating piece, a spring, an electromagnetic coil, a water inlet and a water outlet. The valve seat is provided with the water inlet and the water outlet which communicate through a channel. The valve seat and the valve core seat are fixedly arranged. The water outlet is internally provided with a non-return device. The valve core seat is internally provided with a chamber. The chamber is internally provided with the valve core, the rotating piece and the spring. The wall of the chamber is provided with a plurality of chamber guide ribs. The tail ends of the chamber guide ribs are provided with oblique teeth. A plurality of chamber guide grooves are formed among the multiple chamber guide ribs. The periphery of the valve core is provided with a plurality of valve core guide ribs. The tail end of the valve core is provided with oblique teeth. The tail ends of the valve core guide ribs are provided with oblique teeth. The periphery of the rotating piece is provided with a plurality of rotating piece guide ribs. The top of the rotating piece and the tops of the rotating piece guide ribs are provided with oblique teeth. The water valve is installed on a water inlet pipe of the washing machine, the valve core moves along the chamber through pulse energizing, then water inlet and cut-off operation is controlled through the valve core, thus, the heating time is shortened, the noise is reduced, backflow can be prevented, and the water cut-off reaction time can be shortened.

Description

technical field [0001] The invention relates to a water valve and a washing machine equipped with the water valve, belonging to the field of valves and washing machine devices. Background technique [0002] In the washing machine, the electromagnetic water inlet valve is a component used to control the flow direction and flow of water. In the prior art, the electromagnetic force generated by the electromagnetic coil is generally used to pull the spool and bonnet out of the central hole to realize water intake, but there are many problems. Generally speaking, the washing machine takes a long time to feed water. During the water feeding period, the solenoid valve needs to be continuously energized, which consumes a lot of power; the water pressure is low, the water inlet time is longer, the solenoid valve is powered on for a longer time, and the coil of the solenoid valve heats up, which may even cause safety hazards; The solenoid valve has the problem of high noise. During t...
