[0002] With the continuous development of science and technology, refrigerators have more and more additional functions. At present, there is a refrigerator with a drinking water function. A drinking water device is provided on the door body of the refrigerator, so that the user can directly drink the cold water produced by the refrigeration function of the refrigerator, thereby satisfying the user's need to drink cold water directly. As disclosed in CN201611153006.8, the refrigerator door body is provided with a drinking water device and a water intake channel, and the water intake channel connects the inside and outside of the refrigerator door body, wherein the drinking water device includes a water storage tank arranged on the inside of the refrigerator door body and a water intake assembly at least partially arranged in the water intake channel, and the outside of the refrigerator door body is recessed with a receiving space, and the water intake assembly is partially exposed to the receiving space after passing through the water intake channel, so that the user does not need to open the refrigerator door when taking water, and can take water outside the refrigerator door to avoid leakage of cold air in the refrigerator. The water intake assembly includes a water inlet component, a valve core, a water outlet component and a water intake handle. Under the action of an external force, the water intake handle causes the water outlet component to move back and forth along its axial direction relative to the water inlet component to realize the switching of the water intake assembly between an open state and a closed state. However, since its valve core is very close to the water outlet exposed in the receiving space, the cold water in the water tank can enter the inner cavity of the water intake component exposed in the receiving space, so that the outer wall temperature of this area is relatively low, and condensation is very likely to occur on the exposed part of the water outlet component. The condensation phenomenon not only affects the appearance of the refrigerator, but also absorbs dust and debris in the air, affecting the use of the refrigerator. Summary of the invention

It can also be a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] See also Figure 1-5 The present invention provides a water spout structure of a refrigerator water dispenser, which is installed on the refrigerator door body. The water dispenser is composed of a water storage box 20, a water spout 10, and a switch assembly (not shown). The water storage box is arranged inside the refrigerator door body, and the switch assembly is arranged outside the door body. The water spout is used to guide the water in the water storage box from the inside of the refrigerator door body to the outside of the door body or to close the water outlet channel. The switch assembly is used to drive the water spout to open or close the water outlet channel. The refrigerator door body is provided with a water intake channel, and the water spout is at least partially arranged in the water intake channel. The refrigerated drinking water in the water storage box flows out through the water spout, so that people can obtain drinking water at a lower temperature without opening the refrigerator door. The faucet includes a valve sleeve 4, a valve core 3, a valve plug 1, and a reset spring 2. The valve plug 1 is connected to the valve core 3. The valve core moves in the channel of the valve sleeve to make the valve plug open or close the valve port 6. The valve sleeve includes a connecting portion 42 connected to the water outlet of the water storage box, a valve port portion 41 where the valve port 6 is arranged, and an extending portion 43 extending outward from the connecting portion. The connecting portion surrounds the valve port portion, and the valve port 6 is close to or extends into the water outlet 21 of the water storage box. Figure 3 As shown, the valve port 6 extends into the water outlet 21. The connecting portion 42 is provided with an internal thread, which is connected to the water outlet through a thread. A sealing ring 7 is provided at the bottom of the connecting portion 42, so that the water outlet of the water storage box is sealed and connected to the water nozzle, and the cold water in the water storage box can only enter the inside of the water nozzle through the valve port. The water outlet of the water storage box is in the foaming layer of the refrigerator door body. The present invention raises the height position of the valve port of the water nozzle to the vicinity of the water outlet, that is, the low-temperature water is blocked in the foaming layer, so that the wall temperature of the water outlet channel of the water nozzle below the valve port is not lower than the condensation temperature, and the water outlet channel in the water nozzle is connected to the outside atmosphere, thereby achieving the purpose of preventing condensation.

[0023] The valve opening portion 41 is in an inverted cylindrical shape, and the valve opening 6 is opened on the top end surface of the valve opening portion.

[0024] The shaft portion 31 of the valve core passes through the top end surface of the valve port, and the valve plug 1 is nested at the top end of the shaft portion.

[0025] The return spring 2 is sleeved on the shaft of the valve core and is located in the inner cavity of the valve mouth.

[0026] The valve core 3 further comprises a sleeve 32, a water flow channel 30 is arranged between the sleeve and the shaft portion, and the sleeve is sealedly connected to the lower end of the valve mouth portion.

[0027] Furthermore, the sleeve 32 is connected to the valve opening 41 through a soft sealing sleeve 5. The soft sealing sleeve 5 is made of silicone or other soft plastics. When the valve core 3 moves upward, the soft sealing sleeve 5 swells and shortens, and the sleeve 32 and the valve opening 41 maintain a sealed connection. An outer ring sleeve 33 is provided on the outer side of the sleeve, and the outer ring sleeve 33 can slide on the inner cavity wall at the lower end of the extension portion 43. Figure 5 As shown, the extension portion 43 is cylindrical, and its inner diameter is significantly larger than the outer diameter of the valve mouth portion 41, the outer diameter of the soft sealing sleeve 5 in the stretched state, and the outer diameter of the sleeve 32. An annular space is formed between the extension portion 43 and the sleeve 32, the outer ring sleeve 33, the soft sealing sleeve 5, and the bottom end of the valve mouth portion. This space has a good effect on heat insulation, so that the outer wall temperature of the valve sleeve 4 is less affected by the residual cold amount of the water outlet channel, and its wall temperature is higher.

[0028] The outer ring sleeve 33 is provided with a discharge port 34. The bottom end surface of the valve plug is a horizontal surface, and the valve plug is mushroom-shaped, and has a rounded plug top, so that water flows down smoothly along the arc surface, with little noise and no turbulence during the flow process.

[0029] The switch assembly can select the existing refrigerator water dispenser switch assembly. People press the switch assembly to overcome the resistance of the return spring to push the valve core upward, and the top of the shaft moves upward together with the valve plug, the valve mouth opens, and the water in the water storage box enters the water outlet channel inside the water spout through the water outlet and the valve mouth of the water spout, and then flows out from the barrel sleeve outlet of the water spout, so that cool drinking water can be obtained.

[0030] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention. The scope of the present invention is defined by the claims and their equivalents. Any improvements not made through creative work shall be included within the scope of protection of the present invention.
