Abstract
A door with a gas burner on an inner surface and a system for carrying a combustible gas to the burner on the outer surface thereof. The door comprises a pair of metal sheets rigidly connected to one another at the edges thereof, each sheet having input and output openings for the gas mixture that are mutually separated in order to leave an inner space receiving a deflector plate serving as a thermal shield to be swept over on either side by the flow of the gas mixture supplying the burner. This arrangement reduces heat loss through the door; thus, keeping the outer surface cold, avoiding the risk of burns, and preheating the gas mixture. The invention can be used in heating appliances.

A door with a burner for a heating appliance comprising:
- an outer door sheet peripherally attached to an inner door sheet to define an interior door space at their respective central portions, the outer door sheet having an inlet opening with an inlet dimension and the inner door sheet having an outlet opening with an outlet dimension;
- a gas burner attached to the outlet opening;
- a system for feeding a combustible gas mixture to the burner;
- and
- an outer deflector disc peripherally attached to an inner deflector disc to define an interior deflector space at their respective central portions, each of the outer and inner deflector discs having a deflector diameter and being fixedly mounted in the interior door space, the inner deflector disc having a bulging central portion,
- wherein the deflector diameters are greater than and coaxially aligned with the inlet and outlet dimensions,
- wherein the bulging central portion of the inner deflector disc is adapted to deform elastically with respect to the outer deflector disc so as to absorb any stresses generated by changes in temperature, and
- wherein the combustible gas mixture flows into the inlet opening and around the outer and inner deflector discs to penetrate into the burner.
A door with a burner for a heating appliance comprising:
- an outer door sheet peripherally attached to an inner door sheet to define an interior door space at their respective central portions, the outer door sheet having an inlet opening with an inlet dimension and the inner door sheet having an outlet opening with an outlet dimension;
- an annular mouth portion extending away from the outlet opening to define a burner mount;
- a gas burner attached to the burner mount;
- a system for feeding a combustible gas mixture to the burner;
- and
- an outer deflector disc peripherally attached to an inner deflector disc to define an interior deflector space at their respective central portions, each of the outer and inner deflector discs having a deflector diameter and being fixedly mounted in the interior door space,
- wherein the inner and outer deflector discs, the gas burner, and the inlet and outlet openings are coaxially aligned along a longitudinal door axis,
- wherein the combustible gas mixture flows into the inlet opening, around the deflector discs, and through the annular mouth portion to penetrate into the burner, and
- wherein the deflector diameter is larger than the inlet dimension and the outlet diameter so that the combustible gas mixture licks at least a portion of the outer and inner deflector discs before penetrating the burner.
A door with a burner for a heating appliance comprising:
- an outer door sheet peripherally attached to an inner door sheet to define an interior door space at their respective central portions, the outer door sheet having an inlet opening with an inlet dimension and the inner door sheet having an outlet opening with an outlet dimension;
- a gas burner attached to the outlet opening;
- a system for feeding a combustible gas mixture to the burner;
- and
- an outer deflector disc peripherally attached to an inner deflector disc to define an interior deflector space at their respective central portions, each of the outer and inner deflector discs having a deflector diameter and being fixedly mounted in the interior door space,
- wherein the deflector diameters are greater than and coaxially aligned with the inlet and outlet dimensions,
- wherein the combustible gas mixture flows into the inlet opening and around the outer and inner deflector discs to penetrate into the burner, and
- wherein the central portion of the outer deflector disc is adapted to radially distribute the flow of combustible gas mixture around the outer deflector disc and into the burner.
