Abstract
The utility model relates to a water inlet electromagnetic valve for an automatic washing machine, which is composed of a valve body, a filter, a rubber diaphragm, a rigid center, a control coil, a compression spring, a magnetic yoke, a water insulating sheath, a rubber cap, screws, etc. The utility model is characterized in that the magnetic yoke is in a U shape; the lower part of the valve body of an inlet end is provided with a mounting plate; the inner side of the filter is provided with a shunting current device composed of a shunting current plunger and a damping rubber pad; the axle center of the shunting current plunger is provided with through holes, and four to six circulating holes with trapezoid cross section are distributed uniformly around the shunting current plunger; a shunting current groove is arranged on the surface of the shunting current plunger. The utility model has the advantages of simple structure, convenient installation and operation, water inlet constant flow, etc., which enhances and ensures the quality of the automatic washing machine.
Description
The utility model relates to a kind of delivery valve, particularly automatic washing machine water inlet Constant Electric Current magnet valve.
The patent No. provides a kind of automatic washing machine entering water electromagnetic valve for the utility model of 94220719.X, and it is made up of valve body, filter, rubber diaphragm, rigid central, control coil, iron core and compression spring etc.When control coil cut off the power supply, the compression spring orders about iron core pressed to rigid central, and the rubber diaphragm that links one with rigid central just blocks outlet, and current are promptly blocked; When control coil was switched on, iron core moved under the effect of control coil electromagnetic force, had cancelled the compressing to rubber diaphragm, so rubber diaphragm is freely opened under the promotion of intake pressure, current soon go out.The weak point of this electromagnetic valve is: (1) because yoke is the Off font, and magnetic leakage is big, the water delivery effect is undesirable; (2) because arrival end does not have current stabilization mechanism, the size of flow of inlet water directly influences water flow; (3) this electromagnetic valve is installed inconvenient.
For overcoming the weak point that above-mentioned prior art exists, the utility model provides that a kind of magnetic field is stable, water inlet constant current, automatic washing machine easy to install be with water inlet Constant Electric Current magnet valve.
The purpose of this utility model reaches by following measure: a kind of automatic washing machine entering water electromagnetic valve of forming by valve body, filter, rubber diaphragm, rigid central, yoke, control coil, iron core, every water sleeve compression spring etc., feature of the present utility model is to change existing Off font yoke into U type yoke, avoid the big deficiency of magnetic leakage, improved the water delivery effect; At the inboard of arrival end filter installing damping rubber pad and shunting plug, the axle center of this shunting plug has through hole, be provided with the opening of 4～6 and even layings parallel with axis through-hole around the through hole, its cross section is trapezoidal, recessed formation splitter box between axis through-hole and the shunting plug plug face edge; Being provided with installing plate, be convenient to user installation near below the valve body of arrival end.
Description of drawings is as follows:
Fig. 1 is a structural representation of the present utility model
1-screw 2-iron core 3-water proof cover 4-compression spring 5-control coil 6-yoke 7-arrival end 8-filter 9-installing plate 10-damping rubber pad 11-shunting plug 12-port of export 13-valve body 14-rubber diaphragm 15-rigid central 16-rubber cap among the figure
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment: referring to Fig. 1, by the automatic washing machine entering water electromagnetic valve that screw (1), iron core (2), water proof cover (3), compression spring (4), control coil (5), yoke (6), arrival end (7), filter (8), the port of export (12), valve body (13), rubber diaphragm (14), rigid central (15) and rubber cap (16) are formed, feature of the present utility model is to change existing yoke (6) into the U type by the Off font; Establish installing plate (9) in valve body below near arrival end (7); At the inboard of filter (8) installing damping rubber pad (10) and shunting plug (11), form a kind of part flow arrangement, the axle center of shunting plug (11) has through hole, evenly laying 4～6, cross sections parallel with axis through-hole around it is trapezoidal opening, recessed formation splitter box between axis through-hole and the shunting plug plug face edge.When energising, under U type yoke (6) effectively shielded, the electromagnetic field that control coil (5) produces was stronger, makes iron core (2) reliable operation, has improved the water delivery effect.When the discharge of arrival end was big, compressing damping rubber pad (10) was near shunting plug (11), and the trapezoidal opening around blocking, and current can only enter valve body by axle certre hole, thereby played metering function; When the discharge of arrival end hour, damping rubber pad (10) in the raw, current are the axis through-hole by shunting plug not only, and by around trapezoidal opening enter valve body, thereby play the constant current effect.
The utility model compared with prior art has the following advantages: simple in structure; Install and use Convenient; Owing to adopt U-shaped yoke, electromagnetic field intensity and stablizing, thus make the iron core reliable operation, It is satisfactory for result to intake; Because adopting part flow arrangement, output flow is stable, thereby has improved automatic washing The quality of clothing machine.
Claims (2)
