摘要：A ceiling fan includes a connecting portion fixed to a ceiling, an electric motor having a rotation shaft disposed on a lower portion of the connecting portion, a temperature detector provided on a lower portion of the electric motor for detecting a peripheral temperature, and a controller for estimating a room temperature based on the temperature detected by the temperature detector and driving the electric motor according to the estimated room temperature.

主权项：1. A ceiling fan comprising: a connecting portion fixed to a ceiling; an electric motor including a rotation shaft, the rotation shaft connected to a lower portion of the connecting portion; a control substrate disposed under the electric motor; a temperature detector provided on the control substrate, the temperature detector detecting a peripheral temperature near an outer periphery of the electric motor; and a controller disposed on the control substrate, wherein a memory in the controller stores a temperature rise data at a time of operation of the electric motor, the temperature rise data associated with influence of heat from the electric motor, wherein the controller is configured to estimate room temperature by correcting a temperature detected by the temperature detector based upon the temperature rise data, wherein the controller is further configured to control the electric motor according to the estimated room temperature, and wherein the controller is further configured to correct the temperature detected by the temperature detector in accordance with time elapsed after operation is started.
