[0001] The utility model relates to a fan controller, concretely is a small volume distributed fan frequency conversion controller structure. BACKGROUND

[0002] Fan frequency conversion control is a kind of technology that changes fan speed by adjusting the power frequency of motor, to realize the accurate control of air volume and air pressure.This control mode is widely used in industrial and commercial fields, for energy saving, improving system efficiency and optimizing operating conditions.

[0003] But the conventional fan controller is set in the operating end or the fan frequency conversion end.Set in the operating end, then the longer power line is needed to connect the controller and the frequency converter, and the redundant power line has a big security risk, and the power line can cause the controller to abnormally heat, interfere with the information output of the whole equipment, and the longer the power line, the stronger the interference, which can greatly affect the work of other equipment.If set in the fan frequency conversion end, because it is far away from the operator, the operation of the person is very inconvenient.

[0004] Our modular scheme is to place the fan frequency conversion control button in the operating end for convenient operation, and connect it to the frequency converter through signal line to achieve the adjustment purpose.Signal line does not heat compared with power line, and will not affect the operation of the controller due to signal interference.In this way, the operation of the person is facilitated, and the effect of effectively controlling frequency conversion and not affecting the work of other equipment is achieved.

[0026] Please refer to Figures 1-5 As an embodiment of the utility model, the small volume distributed fan variable frequency controller structure comprises a shell main body 1 and a terminal panel 2 which is detachably arranged on the shell main body 1.

[0027] Further comprising a distributedly installed central control module 5 and a switch control module 6, the central control module 5 and the switch control module 6 are in communication with the variable frequency controller 4, and the variable frequency controller 4 is at least one and is integrated in the shell main body 1.

[0028] The variable frequency controller 4 and the terminal panel 2 are interacted through the circuit module 3.

[0032] As a further scheme of the utility model, the shell main body 1 is made of metal material, and the small-size distributed fan frequency conversion controller structure forms a metal fuselage.

[0033] In the embodiment, the metal fuselage can more efficiently help the machine dissipate heat. When the frequency conversion controller structure is installed close to the fan, the length of the power line can be greatly shortened, and the phenomenon that the traditional frequency conversion controller causes the motor to abnormally heat when the fan is too far away from the operation room can be avoided. The modular integrated frequency conversion controller structure mode can greatly reduce the failure rate of the machine and prolong the service life of the machine.

[0038] The small-size distributed fan frequency conversion controller structure in the application is an intelligent modular controller applied to the control of a ventilation fan, which integrates the technical concepts of frequency conversion driving, automation, embedded development and industrial design. The controller can realize soft start and stepless speed regulation of the fan, detect the real-time state of the fan, and comprehensively protect the motor from open phase, overvoltage, overcurrent, undervoltage, overtemperature and overload. The controller is suitable for the scene of using the fan in the fan extraction and air supply system of a commercial kitchen and can realize self-defined linkage with a purifier and a fire extinguishing system.

[0039] The above embodiments are exemplary but not restrictive, and therefore the technical scheme of the utility model can be realized in other specific forms without departing from the spirit or basic characteristics of the utility model, which is included in the utility model.
