Abstract
A vehicle heater includes a heater housing (12), through which heating air to be heated can flow, with a heating air inlet area and with a heating air outlet area. A burner unit is arranged in the heater housing. A combustion air blower is arranged in the heater housing for feeding combustion air to the burner unit. A heat exchanger unit is arranged in the heater housing (12). Heating air flowing through the heater housing (12) can flow around the heat exchanger unit. A combustion air intake muffler (76), which is essentially arranged in the heater housing (12), is associated with the combustion air blower (46).
Claims20
A vehicle heater comprising:
- a heater housing, through which heating air to be heated flows, with a heating air inlet area and with a heating air outlet area;
- a burner unit arranged in the heater housing;
- a combustion air blower arranged in the heater housing for feeding combustion air to the burner unit;
- and
- a heat exchanger unit arranged in the heater housing and around which heating air flowing through the heater housing flows;
- a combustion air intake muffler essentially arranged in the heater housing and associated with the combustion air blower.
A combustion air blower, for a vehicle heater, the combustion air blower comprising:
- a blower body with a feed duct, which feed duct extends with a ring pattern about an axis of rotation and is open on a first axial side of the blower body in a first axial direction;
- a combustion air feed wheel located opposite the blower body on a first axial side, with a ring pattern feed area overlapping the feed duct and with a plurality of feed blades following one another in a circumferential direction about the axis of rotation;
- a blower motor arranged on a second axial side of the blower body, which second axial side is opposite the first axial side of the blower body, and with a motor shaft rotatable about the axis of rotation, the motor shaft being coupled to the combustion air feed wheel for joint rotation about the axis of rotation;
- a feed duct inlet area open towards the feed duct and in the blower body for the inlet of combustion air into the feed duct;
- and
- a combustion air intake muffler arranged essentially on the second axial side of the blower body.
