The mixing unit (4) for combustion gas and combustion air, especially for heating appliances, has a combustion gas pipe (3) protruding into the mixing unit. The combustion gas pipe opens onto a deflection contour in the mixing unit with a space in between. The deflection contour is designed in such a way that a protrusion extends in the direction of the opening of the combustion gas pipe and extends in the flow direction radially towards the outer edge of the mixing unit. |
