WATER DISPENSER

摘要

A water dispenser includes a water supply line having a pierced rod to which a raw water container having a plug is connected. The plug has a valve body formed with a claw portion which is hooked to a head of the pierced rod when the raw water container is connected to the water supply line. A through hole is formed in the head of the pierced rod at its portion closer to the distal end of the head than is its portion which contacts and pushes the claw portion, whereby atmospheric air in the space defined by a peripheral wall portion of the valve body is released into the pierced rod when the head is pushed into the space defined by the peripheral wall portion.

主权项

1. A water dispenser comprising a casing, a temporary water storage tank provided in the casing, a container holder provided in the casing and on which a replaceable raw water container can be placed, a water supply line provided in the casing and through which raw water can be supplied from the raw water container into the temporary water storage tank, and a pierced rod provided in the casing and formed with a raw water intake port through which raw water can be fed into the raw water supply line,
wherein the raw water container comprises a container body and a plug, the plug comprising a plug body fixed to the container body and formed with a valve hole, and a valve body capable of closing the valve hole, wherein the valve body includes a peripheral wall portion configured to be press-fitted into an inner periphery of the valve hole, and a claw portion protruding from the peripheral wall portion over an entire circumference of the peripheral wall portion, wherein the pierced rod has a head, wherein the water dispenser is configured: such that when the head is pushed into the plug body, the head pushes the claw portion of the valve body over an entire circumference of the claw portion until the claw portion gets caught on the head over the entire circumference of the claw portion, and thereafter, the pierced rod is brought into close contact with the inner periphery of the valve hole while pushing the valve body out of the valve hole until the valve body is separated from the plug body; and such that when the pierced rod is pulled out of the plug body, the peripheral wall portion is fitted into the inner periphery of the valve hole while the pierced rod is pulled out of the valve hole until the valve body gets caught on the plug body, and thereafter, the valve body is separated from the pierced rod, and wherein a through hole is formed in a portion of the head closer to a distal end of the head than is a portion of the head configured to contact and push the claw portion such that atmospheric air in a space defined by the peripheral wall portion is released into the pierced rod through the through hole.
