Abstract
A ventilation fan comprises blades, a motor, a frame, a sensing device and a controller. The blades are mounted on the frame and is fittingly connected with the motor fixedly mounted in the frame, the motor is connected with the controller by a cable, the controller is fixedly mounted in the frame, the sensing device is mounted on the outer surface of the frame and connected with the controller, the controller is connected with an external power source, and a control chip and a power regulator are arranged inside the controller. The ventilation fan is simple in structure, whether people are in a room or not is sensed by the sensing device, and the rotation speed of the fan is regulated, so that the rotation speed is reduced when people are not in the room. Accordingly, the service life of the ventilation fan is prolonged, and energy consumption is reduced.
Description
Technical field
The utility model relates to scavenger fan, and a kind of specifically household is used scavenger fan.
Background technique
Along with development of city, high building stands in great numbers, and the indoor air circulation of building is poor, for guaranteeing indoor air quality, needs to use scavenger fan to accelerate cross-ventilation.
For guaranteeing IAQ, scavenger fan generally needs the scavenger fan in the places such as long-time continuous firing, particularly lavatory.
Existing scavenger fan adopts simple mechanical switch, and the rotation speed of the fan of its scavenger fan can't be regulated, and the intelligent degree of scavenger fan is low specifically; Indoor when having or not personnel; All carry out work, when influencing scavenger fan working life, also cause energy waste by fixed rotating speed.
The model utility content
The purpose of the utility model is to overcome the existing deficiency of present scavenger fan, provide a kind of can be from the scavenger fan of main regulation rotation speed of the fan.
The technological scheme that the utility model adopted is: a kind of scavenger fan, comprise blade, motor, frame, induction installation, controller, and blade installation is connected on frame and with the motor that is fixedly mounted in the frame; Said motor is connected with controller in being fixedly mounted on frame through cable; Induction installation is installed in the frame outer surface, and is connected with described controller; Described controller is connected with external power supply, and it is built-in with control chip, power governor.
The utility model is simple in structure, through whether the personnel activity is arranged in the induction installation nernst cell, and then fan is carried out rotational speed regulation, makes it under indoor unmanned situation, reduces rotating speed, and scavenger fan is prolonged working life, reduces energy consumption.
Description of drawings
Accompanying drawing 1 is that the hardware of the utility model connects block diagram, also is that summary is with figure.
