Embodiment Construction

[0024] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0025] In order to better understand the improvement made by the present invention compared with the prior art, the prior art mentioned in the background art section will be analyzed in detail below.

[0026] Such as figure 1 As shown, the existing water valve uses the lower O-ring 16 to be squeezed and deformed to achieve the sealing effect. After long-term use, it is easy to cause wear, distortion or wrinkles of the lower O-ring 16. The cross-section of the lower O-ring 16 Changes will occur, and the sealing effect will decrease. The ejector body 131 and the pilot valve 14 are fixed by the upper O-ring 15. When the spring pressure or water pressure is high, the reliability of the fixed connection at the top of the ejector body 131 is not good, and it is easy to The ejector rod body 13...

Abstract

The invention discloses a water valve, a refrigerator water dispenser and a refrigerator thereof. The water valve comprises a valve body, a water taking mandrel and a pilot valve, wherein the valve body comprises an inner shell and an outer shell; an inner runner is formed in the inner shell; the water taking mandrel comprises a mandrel body and a mandrel seat; the mandrel body extends into the inner runner and is movably connected with the pilot valve; a sealing piece sleeved on the mandrel body is clamped at the bottom of the pilot valve; a regularly upright conical main sealing surface is formed at the bottom of the sealing piece; and a sealing connection opening matched with the regularly upright conical main sealing surface is arranged on the inner shell and is used for disconnecting the water valve when the mandrel body is pressed and connecting the inner shell and the sealing piece in a sealing manner when the mandrel body is reset. The refrigerator water dispenser comprises the water valve disclosed by the invention. The refrigerator comprises the refrigerator water dispenser disclosed by the invention. The water valve is high in sealing property, and during the long-time use, separation of the mandrel body from the pilot valve is avoided.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a water valve, a refrigerator water dispenser and a refrigerator thereof. Background technique [0002] Along with the popularization of refrigerator as a kind of commonly used household electrical equipment, refrigerator has become the requisite household electrical appliance of common family. In order to improve the use efficiency of refrigerators, the multi-functionalization of refrigerators has become a research and development hotspot for refrigerator manufacturers, so refrigerator water dispensers have emerged as the times require. In the refrigerator water dispenser, the sealing performance of the water valve is directly related to the water storage and water intake performance of the water tank of the refrigerator water dispenser. [0003] Such as figure 1 As shown, the existing water valve includes a valve body 11, a spring 12, a water-taking push rod 13 and a pilot...
