Air conditioning unit

An air conditioning unit comprising:

• a rotary door that has a door rotary shaft and an outer door portion rotating integrally with the door rotary shaft at a position a specified distance away outward from a center of the door rotary shaft in a radial direction;
• a case that houses the rotary door;
• a first opening that (i) is located in the case on an outer side of the outer door portion in the radial direction of the door rotary shaft, (ii) is open or closed by the rotary door, and (iii) blows air;
• a partition that is provided in the case and partitions the first opening to form a first air outlet and a second air outlet arranged in an axial direction of the door rotary shaft;
• and
• an air passage that is formed in the case, the air passage in which air flows toward the first opening, wherein
• the partition has a partition rib that protrudes inward in the radial direction,
• the partition rib has a rib tip portion that extends in a circumferential direction of the door rotary shaft,
• the rotary door has a partition seal portion that (i) is fixed to the outer door portion on an outer side of the outer door portion, (ii) has elasticity, and (iii) is located between the outer door portion and the partition rib,
• the partition seal portion is pressed against the rib tip portion in the radial direction and moves slidably with respect to the rib tip portion in conjunction with a rotation of the rotary door around the door rotary shaft,
• the partition seal portion is attached to the outer door portion and has a curved shape protruding outward in the radial direction,
• the partition seal portion has a non-slidable portion at an end in the circumferential direction,
• the non-slidable portion is kept away from the rib tip portion in the radial direction even when the rotary door rotates,
• the rotary door has a stopper that extends from the outer door portion and prevents the non-slidable portion from being separated from the outer door portion,
• the non-slidable portion is located between the stopper and an attachment surface of the non-slidable portion that is attached to the outer door portion,
• the stopper is in contact with the non-slidable portion, the outer door portion has a protruding portion that hollows the non-slidable portion locally,
• the case has:
• a second opening that is located adjacent to the first opening in the circumferential direction and flows air;
• and
• a seal pressing portion that is provided in a boundary area between the first opening and the second opening,
• the rotary door has:
• a first flange and a second flange that are formed in a peripheral portion of the outer door portion in the circumferential direction;
• a first seal portion that is fixed to the first flange and has elasticity;
• and
• a second seal portion that is fixed to the second flange and has elasticity,
• the rotary door rotates to be located at (i) a first rotary position where the rotary door opens the first air outlet and closes the second opening and (ii) a second rotary position where the rotary door closes the first air outlet and opens the second opening,
• the first flange and the second flange:
• extend in the axial direction and are arranged adjacent to each other in the axial direction;
• and
• form an insertion groove, to which the partition rib is inserted, between the first flange and the second flange,
• the first seal portion and the second seal portion are pressed against the seal pressing portion from a side adjacent to the first opening in the circumferential direction when the rotary door rotates from the second rotary position to the first rotary position,
• the seal pressing portion has:
• a first pressing surface against which an end portion of the first flange on a side adjacent to the insertion groove in the axial direction is pressed through the first seal portion;
• and
• a second pressing surface against which an end portion of the second flange on a side adjacent to the insertion groove is pressed through the second seal portion, and
• the first pressing surface and the second pressing surface incline with respect to the circumferential direction and face a direction away from the partition rib, when viewed in the radial direction.
