360-degree steering double frequency conversion speed regulation electric fan

Abstract

The invention discloses a 360-degree steering double-variable frequency speed control fan. The 360-degree steering double-variable frequency speed control fan consists of a fan cover, a fan base, a base shell, a base cover plate, fan blades, a hand tightening screw rod, a permanent magnetic direct-current brushless motor, a high-torque permanent magnetic direct-current motor, a PCB, a double-nuclear single-chip computer, a rotating ball column and a bearing. The 360-degree steering double-variable frequency speed control fan is characterized by being a double-motor driving structure; an air supply part is driven by the permanent magnetic direct-current brushless motor; a 360-degree head shaking steering part of the fan base is driven by the high-torque permanent magnetic direct-current motor; the double-motor control is realized by a circuit on the PCB; and the double-nuclear single-chip computer can control variable frequency speed control of the permanent magnetic direct-current brushless motor and the high-torque permanent magnetic direct-current motor side by side. The 360-degree steering double-variable frequency speed control fan serves as an indoor circulation variable frequency fan for use in four seasons, reaches the lowest power consumption of 3 watt, can be applied to the places of families, restaurants and cinemas, is preferably matched with an air conditioner or other heating equipment for use, and is an optimal updating product of a conventional ventilation fan or a ventilation fan.

Description

technical field [0001] The invention relates to a 360-degree steering double-frequency conversion speed-regulating electric fan, which can remarkably circulate indoor air, and is a new type of household electrical appliance. Background technique [0002] Air-conditioning heating and cooling equipment can effectively improve the indoor temperature, but people often find that after turning on the air-conditioning heating and cooling equipment indoors, the temperature difference between the ground and the roof is often very large, which makes people feel uncomfortable, especially those who suffer from air-conditioning syndrome The crowd is not suitable for blowing air conditioners. On the other hand, due to poor indoor air circulation, if clothes are dried in the room, mold or peculiar smell will also be produced in the closed room. How to effectively promote the alternation of indoor airflow, solve the problem of indoor air stagnation, and realize the balance of indoor temper...

[0002] Air-conditioning heating and cooling equipment can effectively improve the indoor temperature, but people often find that after turning on the air-conditioning heating and cooling equipment indoors, the temperature difference between the ground and the roof is often very large, which makes people feel uncomfortable, especially those who suffer from air-conditioning syndrome The crowd is not suitable for blowing air conditioners

On the other hand, due to the poor indoor air circulation, if the clothes are dried in the room, it will also cause mold or peculiar smell in the closed room.
