Variable-frequency fan

Abstract

The invention discloses a variable-frequency fan, belonging to a household appliance. The variable-frequency fan mainly solves the problems that the electric energy of the traditional electric fan is wasted and the rotation speed needs to be manually regulated. The structure comprises a fan body composed of a fan head, a support bar and a base, wherein the rear part of the fan head is provided with a transducer; the base is provided with a room temperature sensor and a control device; one side of the base is connected with a power line; and the controller, the room temperature sensor, the transducer and the fan head are electrically connected. The operation speed of the fan disclosed by the invention can be reasonably regulated according to indoor temperature; the transducer can be used for changing the revolving speed of blades, reducing fan starting and stopping times and avoiding frequently starting, preventing from generating large transient currents again and again, improving an energy efficiency ratio and simplifying operation programs; and thus, the fan brings convenience for lives of people.

Description

technical field [0001] The invention relates to a household appliance, in particular to a variable frequency fan. Background technique [0002] In order to effectively improve and enhance the indoor air quality, lower the ambient temperature, and avoid heatstroke, many people choose to use electric fans in summer, using physical principles to cool down and cool off, which is a healthy and energy-saving way; but the traditional electric fans have a single function. The final speed control needs to be adjusted manually, and the speed cannot be selected according to the ambient temperature. Choosing a high speed when the room temperature is low will waste resources, and choosing a low speed when the room temperature is high will cause insufficient wind power and cannot effectively adjust the room temperature. , causing inconvenience to use. Contents of the invention [0003] The object of the present invention is to provide a variable frequency fan, which has the characteris...
