Abstract: A beverage dispenser is proposed which includes a soft raw water container and which makes it possible to spontaneously use up drinking water in the container. A water passage tube (12) of a container connecting portion (10) includes a tubular partitioning wall (13) dividing the interior of the water passage tube (12) into a water passage (14) communicating with a water passage hole (14a), and an air passage (15) communicating with the water passage (14) through a small air passage hole (15a). A water passage pipe (16) is connected to the water passage (14). The water passage tube (12) has a base portion (12a) formed with an opening (15b) communicating with the air passage (15). An air passage pipe (17) is connected to the opening (15b) and hangs vertically downwardly into a low-temperature tank (2). An on-off valve (19b) is provided at the free end of the air passage pipe (17) which is adapted to open when the water level in the low-temperature tank (2) lowers.

Abstract: An air sterilizing chamber is proposed which can effectively sterilize air to be brought into contact with drinking water in a water server. The sterilizing chamber includes a case having an air inlet port and an air outlet port, and defining an air compartment, an air inlet passage through which the air compartment communicate with the air inlet port, and an air outlet passage through which the air compartment communicates with the air outlet port. The sterilizing chamber further includes an ozone generator mounted in the air compartment and capable of converting oxygen in the air compartment to ozone, an inlet-side ozone-decomposing filter mounted in the air inlet passage at a higher level than the air compartment, and an outlet-side ozone-decomposing filter mounted in the air outlet passage at a higher level than the air compartment.

Abstract: A beverage dispenser has a simple configuration that prevents invasion of bacteria into a tank or a raw water container. An air intake 13 is provided on the top of a cold tank 4 so that air is taken in as the water level in the tank is lowered, and an air chamber 14 having an air inlet 16 for the outside air is connected to the air intake 13. In the air chamber 14, an ozone generator 15 generating ozone from oxygen in the air from the air inlet 16 is provided so that bacteria included in the air from outside is killed in the air chamber 14 connected to the air intake 13 by the excellent bactericidal effect of ozone. Invasion of bacteria into the tank or the raw water container is thus prevented with this simple configuration.
