Abstract

The invention belongs to the technical field of indoor ventilation, and discloses a bidirectional ventilation ventilator. The bidirectional ventilation ventilator comprises an air blowing device and apower device; the power device comprises a power supply and a control unit, the power supply is connected to the air blowing device through a motor, and the shell of the motor is connected to a wallbody; and the air blowing device is a fan, one side of the fan is in communication with a ventilation pipeline, the fan is connected to the shaft end of the motor, and the shaft end of the motor can rotate clockwise or anticlockwise. According to the bidirectional ventilation ventilator, the motor capable of rotating clockwise or anticlockwise is arranged, so that the fan rotates clockwise or anticlockwise, indoor air replacement is facilitated, and the indoor air replacement is more facilitated by air exhausting from a room to outside especially when the room is fully filled with harmful gas.

Description

technical field [0001] The invention belongs to the technical field of indoor ventilation, and in particular relates to a two-way ventilation fan. Background technique [0002] Air pollution, also known as air pollution, according to the definition of the International Organization for Standardization (ISO), air pollution usually refers to: due to human activities or natural processes, some substances enter the atmosphere, present a sufficient concentration, and reach a sufficient time. Phenomena that are thereby detrimental to the comfort, health and welfare of humans or the environment. With the rapid development of our country's economy, our country has achieved relatively rich economic results in recent years, but when we enjoy the convenience brought by the rapid economic development, it also brings a certain impact to our environment. [0003] Ventilation windows are also called breathing windows and ventilation windows. According to the principle of atmospheric flow ...
