Evaporator burner for a mobile heating device

A vehicle heating device, comprising

• an evaporator burner having combustion chamber, an evaporator accommodation, and an evaporator element for evaporation of liquid fuel,
• wherein the evaporator element is accommodated in the evaporator accommodation at a side facing the combustion chamber,
• wherein at a side of the evaporator accommodation facing away from the combustion chamber, the evaporator burner comprises at least one combustion air guide element which is arranged such that a combustion air flow path extending at least along a portion of a base wall of the evaporator accommodation is formed between the combustion air guide element and the base wall of the evaporator accommodation,
• wherein the combustion air guide element and the evaporator accommodation are formed such that the combustion air flow path extends from a combustion air inlet, which is provided centrally above the base wall of the evaporator accommodation, at least partly radially outward along the base wall, wherein the combustion air flow path leads into a ring-shaped combustion air pre-chamber which is formed ring-shaped around the combustion chamber,
• wherein the evaporator burner comprises flow guide elements in the combustion air flow path in the region between evaporator accommodation and combustion air guide element in such a manner that in operation a flow component in the circumferential direction is impressed onto the flowing combustion air, and
• wherein the flow guide elements extend up to the evaporator accommodation across a slit formed between the evaporator accommodation and the combustion air guide element over the region of the base wall of the evaporator accommodation.
