Abstract
A gas-flame heated, self-contained kettle comprises a housing (12); a gas burner (14) contained within the housing (12); a container (16) for the fluid (18) to be heated, positioned within the housing (12) and above the burner(14); and exhaust duct (22) leading from an area (24) above the burner (14), through the container (16), and out of a surface of the housing (12). Excess heat and combustion gases are exhausted in heat-exchanged contact with fluid in the container (16) via the ducts (22), for augmented heating of the fluid with simultaneous protection and insulation of the housing (12).
Claims13
An automatic shut-off, gas-flame heated, self-contained kettle, comprising:
- a housing;
- a gas burner contained within said housing;
- a container for the fluid to be heated, positioned within said housing and above said burner;
- a chamber within said housing for containing a compressed gas container;
- a gas feed line leading from said compressed gas container to said gas burner;
- exhaust ducts leading from an area above said burner, through said container, and out of a surface of said housing, whereby excess heat and combustion gases are exhausted in heat-exchange contact with fluid in said container via said ducts, for augmented heating of said fluid with simultaneous protection and insulation of said housing;
- and
- an automatic shut-off valve for closing said gas feed line, said valve being operatively linked to a plurality of sensors which close said valve
- in the absence of a flame at the burner;
- or
- in the absence of fluid in said fluid container;
- or
- on the attainment of a preset temperature within said fluid.
An automatic shut-off, gas-flame heated, self-contained kettle provided with reignition means, comprising:
- a housing;
- a gas burner contained within said housing;
- a container for the fluid to be heated, positioned within said housing and above said burner;
- a chamber within said housing for containing a compressed gas container;
- a gas feed line leading from said compressed gas container to said gas burner;
- exhaust ducts leading from an area above said burner, through said container, and out of a surface of said housing, whereby excess heat and combustion gases are exhausted in heat-exchange contact with fluid in said container via said ducts, for augmented heating of said fluid with simultaneous protection and insulation of said housing;
- an electric battery;
- an ion sensor projecting into the gas flame;
- a spark ignition device which is connected to said electric battery and said ion sensor to reignite an extinguished gas flame;
- and
- an automatic shut-off valve for closing said gas feed line, said valve being operatively linked to a plurality of sensors which close said valve
- in the absence of fluid in said fluid container;
- or
- on the attainment of a preset temperature within said fluid.
