A compact appliance for rapidly electrically heating small quantities of water and dispensing the heated water into vessel includes a housing enclosing a water heating reservoir provided with an electric heating element and connected to a manually actuated water dispensing valve. The housing is provided with a single manually operable lever which is movable in a first direction to close a normally open, manually closed, thermostatic switch is series with the heating element and responsive to the temperature of the reservoir to initiate the water heating operation. After the water is heated, the lever is movable in the opposite direction to actuate the valve to dispense heated water. The valve is integrated with the wall of the housing to minimize the number of parts and simplify the design.
An improved electric water heating appliance comprising a housing enclosing a water heating reservoir and valve means controlling the dispensing of water from said reservoir, said reservoir having an electric heating element mounted in good heat exchange relation therewith for heating the water therein, support means for mounting said housing over a liquid receiving vessel, said housing having a dispensing passageway with an outlet from said reservoir connected to said passageway, said valve means including a valve member movably mounted in said passageway to selectively seal said passageway, a thermostatic normally open, manually closable switch connected in series with said heating element and mounted in said housing to respond to the temperature of said reservoir, a manually operable lever mounted in said housing for selectively actuating said valve member and said thermostatic switch, said lever having one end extending exteriorly of said housing for manual operation and the other end pivoted within said housing, said lever being biased to a first rest position in which said valve member is in sealed engagement with said passageway and said lever out of actuating engagement with said thermostat, said lever being pivotal in one direction to a second position in which it moves said valve member to its open position in which liquid flows through said passageway, said lever being pivotal in a direction opposite to said one direction to a third position wherein it closes said thermostatic switch.
An improved electric water heating appliance comprising a housing enclosing a water heating reservoir and valve means controlling the dispensing of water from said reservoir, said reservoir having an electric heating element mounted in good heat exchange relation therewith for heating the water therein, support means for mounting said housing over a liquid receiving vessel, said housing having a dispensing passageway formed integrally with one wall thereof with a reservoir outlet connected to said passageway, said valve means including a valve member movably mounted in said passageway to selectively seal said passageway, a thermostatic switch connected in series with said heating element and mounted to respond to the temperature of said reservoir, said switch being normally open and manually closable and on being actuated to its closed position will remain in said closed position until the water in the reservoir is heated to the boiling temperature at which point the switch automatically opens, manually operable means for closing said thermostatic switch and for moving said valve member from a position in sealed engagement with said passageway to an open position permitting liquid flow through said passageway, said dispensing passageway including an inlet passageway interconnected with an offset passageway molded integrally with said housing, said inlet and offset passageways being parallel and offset with respect to each other, a conduit interconnecting said reservoir outlet with said inlet passageway, said offset passageway terminating in a valve seat, said valve member including a valve guide and a closure portion, said closure portion engaging said valve seat to seal said offset passageway against liquid flow, the wall of said offset passageway being formed with an elongated opening for slidably supporting said valve guide, and spring means biasing said closure portion against said valve seat.
