AI Technical Summary
Existing refrigerators have complex water supply structures, and the cost of setting up and maintaining multiple water control valves is high. Furthermore, they cannot operate multiple water supply modes simultaneously.
Three water outlets are set on the water control valve of the refrigerator, and the valve core assembly controls their opening or closing, so that the cold water channel and the normal temperature channel of the ice maker and water dispenser can be supplied with water simultaneously or separately, simplifying the water supply control structure.
It reduces the setup and maintenance costs of the refrigerator, reduces power consumption, and improves the flexibility of the water supply mode and user experience.

Abstract
Claims
1. A refrigerator characterized by comprising: The refrigerator includes a cabinet, a door, an ice maker, a water tank, a water dispenser, and a water control valve. The cabinet has a freezer compartment and a refrigerator compartment. The door covers the refrigerator compartment. The ice maker is installed in the freezer compartment. The water tank is installed in the refrigerator compartment. The water dispenser is installed in the door and has at least a cold water channel and a room temperature water channel. The cold water channel is connected to the water tank. The water control valve is installed in the housing and includes a valve body and a valve core assembly. The valve body has a valve cavity, and the valve body has at least a first outlet, a second outlet, and a third outlet, all of which are connected to the valve cavity. The first outlet is connected to the ice maker, the second outlet is connected to the cold water channel through the water storage tank, and the third outlet is connected to the ambient temperature water channel. The valve core assembly is movably connected to the valve body and is used to switch between the first outlet, the second outlet, and the third outlet, and to open or close any one, any multiple, or all of the first outlet, the second outlet, and the third outlet.
2. The refrigerator according to claim 1, characterized in that, The valve core assembly includes a rotating shaft, a rotor, a moving valve core, and a second coil. The rotating shaft is placed inside the valve cavity and rotatably connected to the valve body. The rotor and the moving valve core are both inserted through and fixed to the rotating shaft, and are located along the axial direction of the rotating shaft. The moving valve core is located below the rotor and abuts against the valve body. The second coil is wound around the outer wall of the valve body and is located on the outside of the rotor along the circumferential direction of the rotating shaft. The moving valve core has multiple through holes. When the second coil drives the rotor to rotate the shaft, the shaft drives the moving valve core to rotate relative to the valve body, so that one or more of the through holes can be aligned with the first outlet, the second outlet and the third outlet respectively or simultaneously.
3. The refrigerator according to claim 2, characterized in that, The first outlet, the second outlet, and the third outlet are all located at the bottom of the valve body along the axis of the rotating shaft, and the centers of the first outlet, the second outlet, and the third outlet are located on a circular arc. Along the axial direction of the rotating shaft, the orthographic projection of the center of each through hole onto the valve body lies on the arc.
4. The refrigerator according to claim 3, characterized in that, The plurality of through holes include at least a first hole, a second hole, a third hole, a fourth hole, and a fifth hole, and the first hole, the second hole, the third hole, the fourth hole, and the fifth hole are arranged at intervals in sequence around the circumferential direction of the rotating shaft; On the arc, the central angle between the first hole and the second hole is α1, the central angle between the first hole and the third hole is α2, the central angle between the first outlet and the second outlet is α3, the central angle between the first outlet and the third outlet is α4, and the central angle between the fourth hole and the fifth hole is α5, where α1=α3, α2=α4, and α5=α4.
5. The refrigerator according to claim 4, characterized in that, On the arc, the central angle between the third hole and the fourth hole is α6, α6 > α3; the central angle between the fifth hole and the first hole is α7, α7 > α4.
6. The refrigerator according to claim 2, characterized in that, The valve body is provided with a positioning post, and the moving valve core is provided with a mating part. The mating part is circumferentially limited by the positioning post, which is used to control the second coil to be de-energized when the moving valve core rotates to the initial position.
7. The refrigerator according to claim 2, characterized in that, The valve core assembly also includes a sealing gasket, which is fixed to the valve body, and the moving valve core abuts against the inner bottom wall of the valve body through the sealing gasket.
8. The refrigerator according to claim 2, characterized in that, The water control valve also includes a first coil and an iron core. The first coil is wound around the outer wall of the valve body. The iron core passes through the rotating shaft and is spaced above and below the rotor in the axial direction of the rotating shaft. The first coil is located outside the iron core along the circumferential direction of the rotating shaft. When the first coil is energized, the iron core drives the rotating shaft to move the moving valve core away from the outlet along the axis of the rotating shaft, and the moving valve core separates from the inner bottom wall of the valve body.
9. The refrigerator according to claim 8, characterized in that, The valve chamber has a driving chamber and a main body chamber distributed vertically along the axis of the rotating shaft. The rotor and the iron core are located in the driving chamber, and the moving valve core is located in the main body chamber.
10. The refrigerator according to claim 9, characterized in that, The valve core assembly also includes an elastic element, which is wound around the rotating shaft. One end of the elastic element is connected to the upper cavity wall of the main body cavity in the axial direction of the rotating shaft, and the other end is connected to the moving valve core.
