Abstract

A kettle (1) is provided having a body (2) with a lowermost outer periphery (3), a water chamber (4) inside the body wherein the water chamber has a bottom (5), a lower region (6) immediately above the bottom and a central region (7) that together define a maximum volume of water of at least 1 litre, and typically from 1.4 to 1.8 litres. A transparent wall section or window (9) enables visual observation of the water level. Electrical heating means (11, 21, 27, 28) are provided for heating the water. The lower region of the water chamber has an average horizontal sectional area that is not more than 75%, and preferably not more than 50% of the area enclosed by the lowermost outer periphery. This enables one or 2 cups of water to occupy a greater vertical height in the water chamber and a minimum volume of water of 400 millilitres, and preferably 300 millilitres or less to be visible through the transparent wall section or window. The arrangement greatly facilitates introducing only one or two cups of water into the kettle.

Claims

1. A kettle having a body with a lowermost outer periphery, a water chamber inside the body wherein the water chamber has a bottom, a lower region immediately above the bottom, a central region terminating in an upper maximum recommended operating volume, and an upper region constituting a head space, the water chamber having a maximum operating volume suitable for receiving at least 1 litre of water, a transparent wall section or window through which a volume of water within the water chamber can be visually observed between at least a minimum and a maximum recommended operating volume, and electrical heating means associated with said lower region of the water chamber for operatively heating water present in the water chamber, wherein the lower region of the water chamber has a capacity of not less than 200 millilitres, it has an average horizontal sectional area that is not more than 75% of the area enclosed by the lowermost outer periphery of the body, and a minimum volume of water of 400 millilitres or less is visible through the transparent wall section or window.

2. A kettle as claimed in claim 1 in which the minimum volume is not more than about 300 millilitres.

3. A kettle as claimed in claim 1 in which the maximum operating volume of the water chamber is at least 1.2 litres.

4. A kettle as claimed in claim 3 in which the maximum operating volume of the water chamber is from 1.4 to 2.0 litres.

5. A kettle as claimed in claim 1 in which the horizontal sectional area of the lower region of the water chamber has an average cross-sectional area that is less than 65% of the area enclosed by the lowermost outer periphery of the body.

6. A kettle as claimed in claim 5 in which the lower region of the water chamber has an average cross-sectional area that is not more than 50% of the area enclosed by the lowermost outer periphery of the body.

7. A kettle as claimed in claim 1 in which the capacity of the lower region of the water chamber is from 0.25 litres to 0.5 litres.

8. A kettle as claimed in claim 1 in which the lower region of the water chamber is formed as a diametrical channel extending between opposite sides of the lowermost outer periphery.

9. A kettle as claimed in claim 1 in which the lower region of the water chamber is formed as a central reduced diameter region of smaller cross-sectional size than the lowermost outer periphery of the body.

10. A kettle as claimed in claim 1 in which the lower region of the water chamber is of annular shape with a central raised part of the bottom of the water chamber forming an inner wall to the annular lower region of the water chamber.
