Abstract

A combustion heater ( 110 ) that is provided with a heating plate ( 126 ); a placement plate ( 120 ) disposed opposite the heating plate; an outer wall ( 122 ) provided around the outer circumference of the heating plate and the placement plate; a partitioning plate ( 124 ) that is disposed opposite the heating plate and the placement plate inside a space enclosed by the heating plate, the placement plate, and the outer wall, that forms a lead-in portion ( 134 ) by a gap with the placement plate, and that forms a lead-out portion ( 142 ) by a gap with the heating plate; a linking portion ( 136 ) that links the lead-in portion and the lead-out portion; a combustion chamber ( 138 ) that combusts fuel gas at the lead-out portion near the linking portion; and a flame-stabilization portion ( 140 ) that is provided in the combustion chamber and that maintains the combustion of the fuel gas in the combustion chamber.

First claim

The invention claimed is:

1. A combustion heater comprising:
a heating plate;
a placement plate disposed opposite the heating plate;

an outer wall provided around the outer circumference of the heating plate and the placement plate;
a partitioning plate that is disposed opposite the heating plate and the placement plate inside a space enclosed by the heating plate, the placement plate, and the outer wall, that forms a lead-in portion by a gap with the placement plate, and that forms a lead-out portion by a gap with the heating plate;
a linking portion that links the lead-in portion and the lead-out portion;
a combustion chamber that combusts fuel gas at the lead-out portion near the linking portion; and
a flame-stabilization portion that is provided in the combustion chamber and that maintains the combustion of the fuel gas in the combustion chamber,
wherein the flame-stabilization portion includes a concavity that is provided at a position of the heating plate opposite the linking portion.

2. The combustion heater according to claim 1 , wherein the linking portion is one or a plurality of through-holes provided in the partitioning plate.

3. The combustion heater according to claim 2 , wherein the flame-stabilization portion includes a catalyst.

4. The combustion heater according to claim 3 , wherein the flame-stabilization portion includes a porous body.

5. The combustion heater according to claim 2 , wherein the flame-stabilization portion includes a porous body.

6. The combustion heater according to claim 1 , wherein the flame-stabilization portion includes a catalyst.

7. The combustion heater according to claim 6 , wherein the flame-stabilization portion includes a porous body.

8. The combustion heater according to claim 1 , wherein the flame-stabilization portion includes a porous body.
