Abstract
A water cooler (10) comprises an internal tank (400) that is normally connected to an inverted reservoir (200) and to a delivery spout (122). A cup shaped filter (300) is placed in the water passage (138, 152, 402) leading from the reservoir to the tank. The filter contains filtration material. It also has microscopic openings (323) in its cover and base (306) through which water passes into and out of a filter cup.
Claims19
A water cooler adapted for use with a reservoir having an outlet mouth within which is a normally closed closure valve that is movable to an open position in which it exposes delivery ports at the mouth, wherein the water cooler comprises:
- a tank that is connected to an outlet spout from which water is dispensed,
- a water passage leading to the tank, and
- a support on which the water reservoir may be placed in inverted position to deliver water to the water cooler, the support including an inlet that in use is connected to the water reservoir and that communicates with the water passage to deliver water to the tank, and
- a removable filter located in the water passage between the port and the inlet, the filter being shaped with an upwardly projecting portion which is capable of engaging the closure valve to move it into the open position when the reservoir is placed in position on the cooler.
A water cooler comprising
- a tank having a base, sides and an upper part, the tank being connected to an outlet spout from which water is dispensed,
- a water passage leading to the tank, and
- a support on which an inverted water reservoir may be placed to deliver water to the water cooler, the support including
- an inlet that in use is connected to the water reservoir and that communicates with the water passage to deliver water to the tank and
- a removable filter located in the water passage between a port and the inlet,
- wherein the tank is formed with first and second upwardly projecting tubes formed integrally therewith,
- the first tube being at the upper part of the tank with its mouth constituting the inlet and
- the second tube being at the side of the tank and being open near the base of the tank to constitute a delivery tube.
A water cooler comprising
- a tank having an interior that is connected to an outlet spout from which water is dispensed,
- a water passage leading to the tank, and
- a support on which an inverted water reservoir may be placed to deliver water to the water cooler, the support including an inlet chamber that in use is connected to the inverted water reservoir and that communicates with the water passage to deliver water to the tank,
- a removable filter located in the water passage, and
- an overflow tank connected to the inlet chamber so that when excess water enters the inlet chamber this is conveyed to the overflow tank.
The combination of a water cooler and a water reservoir, wherein the water cooler comprises
- a tank that is connected to an outlet spout from which water is dispensed,
- a water passage leading to the tank, and
- a support on which the water reservoir when inverted may be placed to deliver water to the water cooler, the support including
- an inlet that in use is connected to the inverted water reservoir and that communicates with the water passage to deliver water to the tank and
- a removable filter located in the water passage between a port and the inlet, and wherein the water reservoir mounted on the support and is connected to the water passage, the water reservoir having an enlarged outlet mouth within which is a closure valve incorporating a valve member that is movable from a sealing position to an open position in which it permits water to flow through the valve.
