Abstract

Abstract A compact appliance for rapidly heating small quantities of water and dispensing the heated water into a cup or vessel. The appliance includes a stainless steel reservoir having a heating element brazed to the bottom thereof and a thermostat which extends through the bottom wall of the reservoir to sense the temperature of the liquid contained therein. The thermostat is a manually resettable thermostat which is operable by means of a lever extending through the front wall of the appliance in close proximity to a second lever which operates a valve to dispense the heated liquid into a vessel. The cover for the reservoir is provided with means to return the condensed water vapor to the reservoir rather than permitting it to run into the interior of the housing.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 229 words
A water heating appliance comprising a housing of plastic heat insulating material having a base, a support extending upwardly from said base, and a reservoir enclosing portion; said base including means for supporting a small open vessel adjacent to said support; said reservoir enclosing portion having a top wall with an opening formed therein and a closure for said opening; a lightweight reservoir of drawn sheet metal having a low heat capacity and being cup shaped with a mouth provided with an outwardly extending peripheral flange; said reservoir being received in said reservoir enclosing portion with said flange in sealed engagement with said top wall; a sheathed heating element having a wattage in excess of 1,000 watts brazed to the bottom of said reservoir; a manually resettable thermostatic switch secured to said reservoir and responsive to open the electrical circuit to said heating element when the water in said reservoir is at a temperature below the boiling point; said thermostat being mounted in the bottom of said reservoir extending through an opening to respond to the temperature of the water within said reservoir; a bottom outlet in said reservoir; manually operable valve means connected to said bottom outlet to control the flow of water from said reservoir and having dispensing means extending outwardly from said reservoir enclosing portion above said vessel support means to discharge water into said vessel.
Claim 2
Dependent Claim 229 words
A water heating appliance comprising a housing of plastic heat insulating material having a base, a support extending upwardly from said base, and a reservoir enclosing portion; said base including means for supporting a small open vessel adjacent to said support; said reservoir enclosing portion having a top wall with an opening formed therein and a closure for said opening; a lightweight reservoir of drawn sheet metal having a low heat capacity and being cup shaped with a mouth provided with an outwardly extending peripheral flange; said reservoir being received in said reservoir enclosing portion with said flange in sealed engagement with said top wall; a sheathed heating element having a wattage in excess of 1,000 watts brazed to the bottom of said reservoir; a manually resettable thermostatic switch secured to said reservoir and responsive to open the electrical circuit to said heating element when the water in said reservoir is at a temperature below the boiling point; said thermostat being mounted in the bottom of said reservoir extending through an opening to respond to the temperature of the water within said reservoir; a bottom outlet in said reservoir; manually operable valve means connected to said bottom outlet to control the flow of water from said reservoir and having dispensing means extending outwardly from said reservoir enclosing portion above said vessel support means to discharge water into said vessel.
Claim 3
Dependent Claim 51 words
The combination of claim 1 including first lever means pivotally mounted on said reservoir enclosing portion and engagable with said valve means to control the flow of water from said reservoir, and second lever means pivotally mounted on said reservoir enclosing portion and engagable with said thermostatic switch to reset it.
Claim 4
Dependent Claim 56 words
The combination of claim 2 wherein said valve means includes a plastic housing and is rigidly supported on the inside of said reservoir enclosing portion with said dispensing means extending downwardly through an opening in the bottom of said reservoir enclosing portion, a silicone rubber tube providing a fluid connection between said reservoir and valve means.
Claim 5
Dependent Claim 79 words
The combination of claim 1 wherein said closure includes a flat body portion which overlies the mouth of said reservoir and a peripherally disposed downwardly extending lip on said body portion, said closure having a downwardly extending cylindrical wall which is spaced from and projects into said reservoir to restrict water condensation to the area of said closure within said cylindrical wall, said lip being positioned outwardly of said cylindrical wall and engaging said top wall surrounding said reservoir.
Claim 6
Dependent Claim 72 words
The combination of claim 4 wherein said closure is pivoted to said housing by a hinge formed in part by one edge of said closure lip, said closure having a condensate flow baffle which extends across said body portion between said hinge and said cylindrical wall to direct the flow of condensation deposited on said closure Outside of said cylindrical wall back into said reservoir when said closure is opened and closed.
Claim 7
Dependent Claim 215 words
A water-boiling appliance comprising a small capacity reservoir being of cup shape with a heating element in good heat exchange relation with the bottom wall thereof, ''''said reservoir having a bottom outlet a housing which supports said reservoir'''' with said outlet above a recessed pocket in which a cup or receptacle may be placed, said housing having a top opening in which said reservoir is received, said reservoir being formed at the mouth thereof, with a flange which overlies the housing portion defining said opening and being sealed thereto by a sealant material, a cover for said reservoir pivoted to said housing, said cover having a downwardly extending cylindrical wall which is spaced from and projects into said reservoir to restrict water condensation to the area of said cover within said cylindrical wall, said cover includes a flat body portion which overlies the mouth of said reservoir and a peripherally disposed outwardly extending lip on said body portion, said lip being positioned outwardly of said cylindrical wall and engaging said housing surrounding said reservoir, said cover being pivoted to said housing by a hinge formed in part by one edge of said cover lip, said wall extending from said closure a distance greater than the distance from the mouth of said reservoir to said hinge.
