Abstract
The invention concerns a stove comprising a burner, a combustion chamber, transport and exit ducts for the combustion gases, and at least one heating unit, such as a hearth plate or an oven. According to the invention, the stove comprises warm air duct with inlet and outlet and a blower, arranged to circulate air into said warm air duct to be heated by the heating unit and out from said duct. The stove may consist for instance of a lid lowerable over the hearth plate so that the warm air duct becomes confined between the lid and the hearth plate. When the stove comprises an oven, the warm air duct may conduct the air to be heated on the other hand into the oven and on the other hand into the intermediate space confined between the outer surface of the transport duct for the combustion gases.
Claims5
A stove comprising:
- a combustion chamber;
- a burner disposed in said combustion chamber;
- substantially gas-tight transport and exit ducts for combustion gases;
- heating means juxtaposed to and in heat exchange relationship with said combustion chamber and said transport duct through a heat conduction surface, said heating means being heated by heat generated by said burner and primarily intended for food preparation;
- substantially gas tight warm air duct means including an inlet thereto and an outlet therefrom and a blower, said warm air duct means cnducting air into said heating means past said heat conduction surface for heating air;
- a jacket surface, said warm air duct means being confined between said heating means and said jacket surface;
- said heating means including at least one hearth plate constituting a heating unit adjoining on and in heat exchange relationship with said combustion chamber and said transport duct for said combustion gases;
- and
- a hearth plate lid constituting said jacket surface positionable over said hearth plate and confining said warm air duct means between said lid and said hearth plate.
