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.

Abstract: A receiving unit of a CPAP apparatus includes a base member, a receiving case, a heating unit, and an elastic member. The receiving case is disposed on an upper side of the base member and includes an opening formed in a lower wall. The heating unit is disposed between the base member and the lower wall of the receiving case. The elastic member is disposed on the base member and holds the heating unit. The heating unit includes a heating element and a thermal conductor. The thermal conductor is disposed on an upper side of the heating element, has a shape wider than a shape of the heating element when the heating element is viewed from the receiving unit in plan view, and includes a peripheral portion that does not overlap the heating element.

Abstract: A blower of a CPAP device is housed inside a main body case of a CPAP device. The blower is roughly divided into a fan unit housing a fan therein, and a delivery tube, through which air sent from the fan passes. In the main body case, a first support member, a second support member, and a third support member are interposed between the main body case and the fan unit to support the fan unit. When viewed from a rotation axis of the fan, the first support member and the second support member are disposed to pinch the blower on the side of a connection point between the fan unit and the delivery tube relative to the rotation axis, and the third support member is located on the opposite side to the connection point between the fan unit and the delivery tube relative to the rotation axis.

Abstract: A box body includes a lower wall, and a side wall and a side wall that are arranged with a space therebetween in which a humidification chamber is capable of being disposed. A cover includes an upper wall having a plate shape and a side wall connected to the upper wall and rotatably connected to the side wall. The humidification chamber includes a main body and a tubular body. The main body stores liquid and has a box shape that is open upward, and the main body includes a chamber side wall and a chamber side wall. The tubular body is mounted on the main body, passes through the chamber side wall, and partially protrudes outside. The humidification chamber is accommodated in the box body with the side wall and the chamber side wall facing one another and with the side wall and the chamber side wall facing one another.

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: An insertion-ejection opening opens in a housing case body of a housing case. A tank is inserted into and ejected from a housing space of the housing case body through the insertion-ejection opening of the housing case body. A portion of an upper-side internal surface of the housing case body forms a case slant surface slanted relative to a surface that is perpendicular to a height direction. In addition, the case slant surface faces toward a side of the insertion-ejection opening. A second discharge opening opens in the case slant surface. A portion of an external surface of the tank forms a tank slant surface slanted relative to the surface that is perpendicular to the height direction. A discharge tank aperture opens in the tank slant surface. In a state in which the tank is housed in the housing case body, the tank slant surface faces the case slant surface.
