Patent EP-3961040-A1 (EP)
Inventor: HUANG HUANWEN
IPC: F04D17/16
Filed: 2020-08-17
Abstract: This application provides a centrifugal fan and an air conditioning apparatus. The centrifugal fan includes a top plate, a baseplate, a motor, a flow guiding cover, and a plurality of blades. A motor mounting hole is disposed at a central position of the baseplate, and the motor has a motor housing. The motor housing is mounted on the motor mounting hole and is fastened to the baseplate, and the motor at least partially extends between the baseplate and top plate. The blades are fastened between the top plate and the baseplate, and the plurality of blades are disposed around the motor. The flow guiding cover is sheathed on an outer peripheral side of the motor housing, and is detachably mounted on the baseplate. In this solution, the flow guiding cover fills a groove formed between the motor housing and the baseplate, to avoid a problem of increased resistance caused when air flows through an area between the motor housing and the baseplate due to discontinuity of contours, thereby reducing impact loss. The flow guiding cover can further play a role in guiding airflow entering and leaving the centrifugal fan, to improve aerodynamic efficiency of the centrifugal fan and reduce noise generated by the airflow.

Abstract: Technologies are generally described for passively powering wireless IoT devices. An actively powered transmitter may transmit a radio frequency (RF) signal over a common channel and information associated with parameters of a reply signal to various passively powered wireless devices. The wireless devices may extract power from the RF signal or other signals in the ambient environment, use the extracted power to perform operations, and backscatter a reply signal over a different channel defined by the RF signal. The reply signal from the passively powered wireless devices may be received by a base station or an actively powered device in the vicinity and forwarded to the base station. Various multiplexing schemes may be employed to prevent collision of reply signals from the passively powered wireless devices.
