Abstract

The invention discloses a control device capable of real time monitoring of extractor hood operating state and a control method. The control device comprises a controller. There are at least two working gears in the controller. The controller is connected with a rotating speed sensor used for detecting a motor rotating speed and a current sensor used for detecting a motor current. The control device comprises a data memory used for storing data of air flow-air pressure values corresponding to currents and data of air flow-air pressure values and efficiency values corresponding to currents, and a displayer used for displaying air flow-air pressure and efficiency information. Whether the extractor hood breaks down is determined through detection of the motor rotating speed v or the motor current i, values of air flow, air pressure and efficiency curves of a related gear are read, thus consumers can know real time air flow, air pressure and efficiency value intuitively and performs adjustment, and energy waste can be avoided.

Description

[technical field]

[0001] The invention relates to a control device capable of monitoring the operating state of a range hood in real time and a control method thereof. [Background technique]

[0002] The display interface of the existing range hood can only display the gear position of the range hood and some auxiliary information, and the user cannot intuitively know the real-time air volume and wind pressure (static pressure) of the range hood. Whether the machine is working normally, whether you should choose other appropriate gears (rotational speed), it is easy to cause insufficient or excess air volume of the hood; Waste of energy.

[0003] When the fan fails to work normally or cannot be shut down in time due to external factors, it is easy to cause the motor to burn out; especially when the pipe network is blocked, the traditional range hood does not give the operator or maintainer a clear fault prompt, and the range hood is in use. Running in this state causes oil...
