1. An air-conditioning apparatus comprising a heat-source detection unit provided at a front of a housing,
wherein the heat-source detection unit includes
an infrared sensor configured to detect a heat source in an air-conditioned space,
a supporting member that supports the infrared sensor, and
a cover member that houses the infrared sensor and the supporting member, the cover member being made of material that does not allow infrared rays to pass therethrough, the cover member having an opening,
wherein the supporting member and the cover member are configured to be rotated about an axis that extends in a vertical direction, and
the infrared sensor is configured to be rotated about the axis that extends in the vertical direction, along with the supporting member, between a reference position where the infrared sensor faces a front of the air-conditioning apparatus and a rotation stop position where the infrared sensor does not face the air-conditioned space,
when the infrared sensor is rotated in a first direction that is a direction from the reference position toward the rotation stop position, and the infrared sensor faces the air-conditioned space, and when the infrared sensor is rotated in a second direction that is a direction from the rotation stop position toward the reference position and that is the opposite direction to the first direction, and the infrared sensor faces the air-conditioned space, the supporting member and the cover member are rotated, with the infrared sensor located to face the opening, and
when the cover member is further rotated from the rotation stop position in the first direction, and the infrared sensor does not face the air-conditioned space, and when the cover member is rotated toward the rotation stop position in the second direction, and the infrared sensor does not face the air-conditioned space, the infrared sensor is located to face part of the cover member in which the opening is not formed.
