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 power estimating apparatus includes a functional unit, at least one converter, a detection unit, and an estimating unit. The functional unit uses an alternating-current power supply. The at least one converter is connected to a branch point between the alternating-current power supply and the functional unit and includes a smoothing capacitor so as to convert an alternating current from the alternating-current power supply into a direct current. The detection unit obtains a total amount of currents supplied to the functional unit and the at least one converter. The estimating unit uses the total amount to estimate an amount of the current supplied to the functional unit. The total amount is obtained by the detection unit in a charge and discharge period during which the smoothing capacitor performs a charge and discharge operation.
