Abstract
The present invention relates to an air conditioner for a vehicle, which includes a dome-type temperature-adjusting door and a dome-type face door rotatably mounted in a mixing chamber of an air-conditioning case, such that a curved surface of the inner face of the temperature-adjusting door and a curved surface of the inner face of the face door can smoothly guide air toward vents according to air discharge modes so as to reduce flow resistance and increase air volume.
Claims9
An air conditioner for a vehicle comprising:
- an air-conditioning case having a defrost vent, a face vent, and floor vents to discharge air to the interior of the vehicle, and a cold air passageway and a warm air passageway formed therein;
- an evaporator located in the cold air passageway;
- a defrost door for adjusting a degree of opening of the defrost vent, a face door for adjusting a degree of opening of the face vent, and a floor door for adjusting a degree of opening of the floor vents, the defrost door, the face door and the floor door being mounted inside the air-conditioning case;
- and
- a temperature-adjusting door mounted inside the air-conditioning case to adjust a degree of opening of the cold air passageway and the warm air passageway,
- wherein the temperature-adjusting door is rotatably mounted in a mixing chamber formed at an exit of the cold air passageway and at an exit of the warm air passageway, wherein cold air and hot air from the cold and warm air passageways are mixed in the mixing chamber, and wherein the temperature adjusting door is a dome-type door for adjusting degree of opening of the cold air passageway and the warm air passageway relative to the mixing chamber,
- wherein the face door is rotatably mounted in the mixing chamber and is a dome-type door for adjusting the degree of opening of the face vent relative to the mixing chamber,
- wherein the face door is configured to close the defrost vent in a vent mode,
- wherein the temperature-adjusting door and the face door are mounted in the mixing chamber in opposite directions,
- wherein a rotary shaft of the temperature-adjusting door and a rotary shaft of the face door are arranged collinearly in a vertical direction,
- wherein the temperature-adjusting door and the face door each have a first end portion located closest to the evaporator and a second end portion spaced from the first end portion,
- wherein an interval between the first end portions of the temperature-adjusting door and the face door is A, an interval between the second end portions of the temperature-adjusting door and the face door is B, and A is smaller than B in all air discharge modes.
