CPAP apparatus

A continuous positive airway pressure apparatus comprising:

• a blower configured to pressurize and feed air;
• and
• a humidifying tank configured to allow the air, pressurized and fed by the blower, to flow thereinto, the humidifying tank having an inner space capable of storing water,
• wherein the humidifying tank includes
• a top wall, a side wall, and a bottom wall defining the inner space,
• a first passage through which the blower communicates with the inner space,
• a second passage through which the inner space communicates with a portion being outside of the humidifying tank and being different from the blower,
• a flow-dividing section facing an inlet when the inlet is defined as an opening of the first passage facing the inner space, and
• a shielding section extending toward the flow-dividing section from an end surface of the first passage on a side in which the inlet is open,
• wherein, when an outlet is defined as an opening of the second passage facing the inner space and a vertical axis is defined as a specific axis intersecting the 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 passing through an opening center of the inlet and being parallel to a direction in which the inlet faces, and
• wherein, when a specific end is defined as an end being one of two ends of the inlet in a direction along an orthogonal axis orthogonal to the vertical axis and being nearer to the opening center of the outlet when the inlet is seen in a direction along the imaginary axis,
• the shielding section extends to the flow-dividing section from a portion included in the end surface and being further toward an opposite side from the opening center of the inlet than the specific end.
