A water dispenser is provided in which drinking water in a raw water container is fed by gravity into a temporary tank through a water fall line, and which is configured such that a negative pressure created in the raw water container is never balanced with the water fall pressure. The interior of a piercing rod (21) piercing through a plug (14) of the raw water container (10) is partitioned into an water passage (22) and an air passage (23) that extend into the raw water container (10) such that the air passage (23) extends from a starting end opening (25) which is smaller than a starting end opening (24) of the water passage (22) into the temporary tank (30). The air passage (23) is opened and closed by a float valve (40) including a valve body (44), and a float (43) afloat on the water in the temporary tank (30) and coupled to the valve body (44). With this arrangement, when a negative pressure is created in the raw water container (10) due to overshooting, and the valve body (44) is pushed upward by air in a valve case pipe (42), the valve body (44) is forcibly moved to the position corresponding to the water level in the temporary tank (30). |
