Lampblack machine and controlling method thereof

Abstract

The invention discloses a lampblack machine and a controlling method thereof. The lampblack machine comprises a blower system and a controlling system; the blower system comprises a motor; and the controlling system comprises a main controlling module, a temperature detecting module and a rotating speed regulating module, wherein the temperature detecting module is used for detecting the winding temperature of the motor and transmuting detected data to the main controlling module, and the main controlling module is used for controlling the rotating speed regulating module to regulate the rotating speed of the motor according to the winding temperature. According to the lampblack machine, the temperature detecting module is arranged, the motor winding temperature of an exhaust system is detected, whether an air outlet of the lampblack machine is subjected to abnormal resistance or not is judged according to comparison of the detecting temperature with the reference temperature value, and the motor is controlled to automatically regulate the rotating speed on the basis of comparison; and when the fact that the air outlet of the lampblack machine is subjected to the abnormal resistance is judged, the rotating speed of the motor is increased, and the normal rotational speed is restored when the abnormal resistance disappears, so that the better smoke removal effect is obtained, andenergy consumption can be reduced.

Description

technical field [0001] The invention relates to the related technical field of range hoods, in particular to a range hood and a control method thereof. Background technique [0002] At present, most household range hoods in middle and high-rise buildings are connected to the public flue for smoke exhaust through the exhaust pipe. The resistance of the range hood will be very large, which will affect the smoke exhaust effect of the user's range hood. Only by increasing the exhaust air volume of the range hood can the range hood exhaust smoke to the public flue smoothly. However, the gears of general range hoods are relatively fixed. No matter how the size of the cooking fume changes, the user can only choose a fixed gear to adjust. Moreover, the motor speed of traditional range hoods is usually adjusted manually, and the range hood cannot be automatically adjusted according to the actual use. Motor speed, time-consuming and labor-intensive. [0003] Alternatively, some rang...

[0002] At present, most household range hoods in middle and high-rise buildings are connected to the public flue for smoke exhaust through the exhaust pipe. The resistance of the range hood will be very large, which will affect the smoke exhaust effect of the user's range hood. Only by increasing the exhaust air volume of the range hood can the range hood exhaust smoke smoothly to the public flue

However, the gears of general range hoods are relatively fixed. No matter how the size of the cooking fume changes, the user can only choose a fixed gear to adjust. Moreover, the motor speed of traditional range hoods is usually adjusted manually, and the range hood cannot be automatically adjusted according to the actual use. Motor speed, time-consuming and labor-intensive

[0003] Alternatively, some range hoods automatically adjust the motor speed by setting sensors to detect the exhaust pressure of the exhaust system. not able to achieve good results
