Abstract: A CPAP apparatus includes a blower and a humidifying tank having an inner space that is capable of storing water. The humidifying tank includes a bottom wall, a side wall, and a top wall. The humidifying tank includes a first passage through which the blower communicates with the inner space and a second passage through which the inner space communicates with a portion that is outside of the humidifying tank and that is different from the blower. When an inlet is defined as an opening of the first passage on the humidifying tank side, an outlet is defined as an opening of the second passage on the humidifying tank side, and an imaginary line segment is imagined to connect the inlet and the outlet along a shortest distance, the CPAP apparatus includes a shielding section that intersects the imaginary line segment.

Abstract: A CPAP apparatus includes a blower and a humidifying tank. The humidifying tank includes a first passage, a second passage, a flow-dividing section, and a facing section. When an inlet IH is defined as an opening of the first passage on the inner space side, the flow-dividing section faces the inlet. The facing section extends toward a bottom wall from an outer peripheral surface of the first passage. When seen along a vertical axis that is a specific axis that intersects the bottom wall, the facing section includes a part that overlaps the inlet. The facing section faces the flow-dividing section.

Abstract: A humidifying tank of a CPAP apparatus includes a first passage, a second passage, a flow-dividing section, and a shielding section. An inlet is defined as an opening of the first passage on an inner space side, an outlet is defined as an opening of the second passage on the inner space side, and a vertical axis is defined as a specific axis that intersects a bottom wall. As seen in a direction along the vertical axis, an opening center of the outlet is located so as to be displaced relative to an imaginary axis that passes through an opening center of the inlet and that is parallel to a direction in which the inlet faces.
