Example Embodiment

[0057] Example one

[0058] The electromagnetic water inlet valve of this embodiment, see Figure 4 , Figure 5 , Figure 6a , Figure 6b , Including the valve body 1, the valve body 1 is provided with a water supply chamber 101 and a water outlet chamber 102, there is a valve seat 103 between the water supply chamber 101 and the water outlet chamber 102, the valve seat 103 is fitted with a diaphragm 2, and the center of the diaphragm 2 has a perforation 201 Inserted in the fitting groove 301 of the diaphragm 3, the valve body 1 is provided with a conduit 4, and the lower end 401 of the conduit 4 flared radially outwardly is pressed against the sealing portion 202 of the periphery of the diaphragm 2 to form a back pressure chamber 104. The center of the diaphragm 3 A guide hole 302 is opened on the periphery, and a side flow channel 303 is opened on the periphery. The water supply chamber 101 communicates with the back pressure chamber 104 through the side flow channel 303. A sole...

Example Embodiment

[0064] Example two

[0065] The electromagnetic water inlet valve of this embodiment, see Picture 9 This embodiment is different from the first embodiment in that: the diaphragm plate 3 is formed by combining the partition A31 and the partition B32, the water inlet 3201 on the partition B32, and the partition A31 and the partition B32 are formed by fitting The pressure loss chamber 33 and the back pressure chamber inlet 3101 on the partition A31 constitute the side flow channel 303.

[0066] Compared with the first embodiment, the manufacturing process of the diaphragm plate is different due to the different structure of the diaphragm plate. In specific practice, the user can make a choice according to the needs.

Example Embodiment

[0067] Example three

[0068] The electromagnetic water inlet valve of this embodiment, see Picture 10 There are one or more protrusions 34 on the outer periphery of the diaphragm plate 3, and the protrusions have a fitting groove 3401, and the outer periphery of the diaphragm 2 also has a corresponding hole 203. The fitting groove 3401 Embedded in the hole 203. The other structure is the same as the first embodiment.

Abstract

The invention discloses an electromagnetic water inlet valve capable of solving the problem that the normal work cannot be carried out due to excessively-low pressure. The electromagnetic water inlet valve comprises a valve body and a valve seat arranged in the valve body, wherein the valve body is provided with a conduit; a piston is arranged in the conduit; the head part of the piston is connected with a piston nut; a convex part is arranged at one end of the piston corresponding to the valve seat; the piston nut is arranged at the convex part; a diaphragm plate has a connecting structure which is provided with a moving space and a top buckle edge of the piston convex part; the piston convex part is positioned in the moving space; the axial length of the piston convex part is less than that of the moving space, so that the piston convex part is hooked with the top buckle edge of the connecting structure after moving towards the direction away from the valve seat for a stroke in the moving space; and the piston convex part continuously moves to drive the diaphragm plate and a diaphragm together to move towards the direction away from the valve seat. The invention is suitable for a water inlet valve of a washing machine and other home appliances.

Description

technical field [0001] The invention relates to an electromagnetic valve, in particular to an electromagnetic water inlet valve assembled in household appliances. Background technique [0002] In the past, the structure of the guided electromagnetic water supply valve is that in the valve body composed of the inlet, the water supply chamber, the valve seat, the outflow chamber and the outlet, a diaphragm and a diaphragm plate for closing the valve seat (the diaphragm is attached to the diaphragm plate, two These are used together as the disc to close the valve seat), and there is also a conduit, which is equipped with a piston made of magnetically conductive material, a piston cap connected to the front end of the piston, a spring on the rear end of the piston, and an electromagnetic coil on the periphery of the conduit , the central protrusion of the diaphragm plate is provided with a guide hole corresponding to the piston cap, and the electromagnetic coil is energized and ...
