Said locating support comprises annular bayonet socket and support chip, annular bayonet socket clamping water inlet, and support chip extends inwardly to the position of delivery port.
The axis direction of said support chip plane, place and delivery port is on same plane.
Space between said support chip and three-way connector body is less than the diameter of anti-siphon ball.
First end of said three-way connector body is provided with locating groove and boss, makes a slip of the tongue with the annular snap of locating support and is full of the location.
The interior edge of the 3rd end of said three-way connector body is provided with the annular cambered surface end with anti-siphon ball contact position.
The utility model is owing to adopted above technical scheme, and with respect to prior art, the anti-siphon three-way connector of the use in washing machine pressure resistant type of the utility model specifically designs to washing machine, and simple in structure, cost is low, and effect is obvious.Structure itself has pipeline and connects design, is implemented in the maximality price ratio of water supply working line under the water under high pressure, satisfies anti-siphon requirement fully.This new structure greatly oversimplify complicated existing scheme and also cost advantage huge, effect is obvious, provides big flood to depress the water supply effect that working environment needs, anti-siphon function is very obvious.
