Description

Water inlet valve actuation supporting structure

Technical field

The utility model belongs to inlet valve technical field, moves supporting structure more specifically to water inlet valve for washing machine.

Background technique

The inlet valve of washing machine plays a part of controlling water source switch, since water has certain operating pressure at work, It can be designed to lead hair action type solenoid valve, mainly be made of two parts, the pilot valve on top, the main valve of lower part.Work as line Enclose no power when, movable core because self weight and reset spring counter-force fall, close the recirculation hole of diaphragm so that by balance hole into Entering water intracavitary on valve plug cannot leak, and due to diaphragm above and below effective pressure area difference, form pressure official post diaphragm and compress On main valve body, valve is closed.After energization, electromagnetic attraction attract movable core rise, upper intracavitary water just through recirculation hole leak to The outlet of valve.The negotiability of recirculation hole need to be greater than the negotiability of balance hole, generate water flow on balance hole sufficiently large Pressure loss, upper intracavitary pressure sharply decline, and the pressure of valve plug cavity of resorption remains identical as import pressure, on such valve plug, The pressure official post diaphragm of lower section bulges upwards, valve opening, water conduction.

Dynamic branch is set up in the lower section of movable core, the opening and closing with membrane engagement control valve, is equipped on dynamic bracket and diaphragm Upper balance hole and the corresponding relief hole of recirculation hole and boosting hole.Because China is distant wide, different zones water quality is different, meeting Cause washing machine with the water stage, user's water quality inferiority causes boosting hole plug, influences the normal use of washing machine.

Specific embodiment

Below against attached drawing, by the description of the embodiment, making to specific embodiment of the present utility model further detailed Thin explanation.

Provided this water inlet valve actuation supporting structure, as shown in Figure 1,2,3, 4, including dynamic rack body 1, move bracket sheet Body 1 is disc-shaped structure, is equipped with relief hole 11 at the middle part of dynamic rack body 1, is equipped with boosting hole 12 in the side of relief hole 11, Dynamic rack body 1 is equipped with the barrier block in blocking foreign body flow direction boosting hole 12.As shown in Figure 1,3, boosting hole 12 is by moving bracket 1 inside bottom surface of ontology is downwardly extending.

In the utility model, as shown in Figure 1, 2, the first embodiment provided, barrier block is on boosting hole 12 The boss 13 of side.Boss 13 is the round boss around boosting hole 12, and boss 23 is equipped with the logical of corresponding connection boosting hole 12 Hole.Increase boosting face by the boosting hole location on dynamic rack body 1, the self weight of the foreign matters such as foreign matter such as silt is sunk, can not By hole 12 of boosting, it can avoid boosting hole 12 and block, promote the service performance of inlet valve.

In the utility model, as shown in Figure 3,4, second of the embodiment provided, barrier block is set on boosting 12 He of hole Convex ribs 14 between relief hole 11.Convex ribs 14 are the circular ring shape convex ribs being arranged concentrically with relief hole 11.By in dynamic rack body 11 surrounding of relief hole at center increases convex ribs 14, and increased convex ribs 14 can hinder part foreign matter, can avoid boosting hole 12 blockings, promote the service performance of inlet valve.

In the utility model, relief hole 11, which has, upwardly extends the annular convex platform to be formed, the valve of annular convex platform and inlet valve Plug contact realizes the purpose of control water source switch to realize the opening and closing of application valve body under the control of the valve plug of main valve.
