Definitions

  • the present invention relates to a water dispenser, in particular to a water dispenser of a refrigerator.
  • the present invention more particularly relates to the valve assembly of the water dispenser.
  • Refrigerators having door-mounted water dispensers for supplying the user with cold drinking water are commonly known in the art.
  • the valve assembly of the water dispenser generally comprises: a passage for conveying the water; at least a first sealing which comprises a flexible material; a sealing surface for leak-tightly contacting the first sealing, wherein the first sealing and the sealing surface are arranged relatively moveably so as to allow opening/closing of the passage; and a resilient member for moving the first sealing relatively towards the sealing surface.
  • WO2015144244A1 discloses a refrigerator which comprises a water dispenser with a valve assembly.
  • a problem with the prior art refrigerator is that the valve assembly of the water dispenser is vulnerable to leakage.
  • the water that leaks through the valve assembly is collected in the tray of the door.
  • the deposits of dust that are formed in the tray give rise to a bad appearance, and thus the user must frequently empty and clean the tray. In such instances, the user satisfaction decreases.
  • An objective of the present invention is to provide a valve assembly for use in a water dispenser of a refrigerator which solves the aforementioned problems of the prior art in a cost-effective way and which is easy to install and has an improved safety against leakage.
  • the valve assembly of the present invention further comprises a fin-like protrusion which encircles the passage, wherein the fin-like protrusion is formed onto a section of the sealing surface such that it protrudes from the sealing surface towards the first sealing in the opening/closing direction, and is further adapted to compress the opposed section of the first sealing in the closed state.
  • a major advantageous effect of the present invention is that the first sealing can be firmly squeezed in the vicinity of the fin-like protrusion in the closed state. Thereby, the risk of leakage can be eliminated or reduced as much as possible, and thus the sealing performance of the valve-assembly can be improved. Thereby, the user satisfaction can be increased.
