Problems solved by technology
Although the above-mentioned control system and control method solve the problem in the prior art that the influence of the kitchen environment and the public flue on the effect of the range hood cannot be comprehensively considered, so that the range hood reduces noise and is energy-saving and environmentally friendly, but its control process is only through the control The speed of the main fan motor inside the range hood is realized, and the air volume adjustment effect is relatively poor

Embodiment Construction
[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0026] like Figure 1 to Figure 5 As shown, the range hood with air volume adjustment in this embodiment includes a main fan 1, a smoke pipe 2 and an auxiliary fan 3, wherein the smoke pipe 2 is connected to the air outlet of the main fan 1, and the auxiliary fan 3 is an axial flow fan and They are connected in series on the smoke pipe 2. In this embodiment, there are two auxiliary blowers 3 and they are connected in series successively. Auxiliary fan 3 includes blade 31, fan casing 32 and fixed bracket 33, the two ends of fan casing 32 are connected on the corresponding port of smoke pipe 2, blade 31 is arranged in fan casing 32, and fixed bracket 33 is installed on the fan casing 32 , during installation, the fixed bracket 33 is fixed on the body of wall. In addition, since the auxiliary fan is hidden in the ceiling of the kitchen, sound-a...

A range hood having an air volume adjusting function comprises a main fan and a smoke tube and is characterized by further comprising a main controller and auxiliary fans mounted on the smoke tube, wherein first pressure sensors are mounted on front sides of blades of the auxiliary fans; second pressure sensors are mounted on back sides of the blades of the auxiliary fans; signal output ends of the first pressure sensors and signal output ends of the second pressure sensors are connected with signal input ends of the main controller; and the main controller controls revolving speeds of motors of the auxiliary fans according to signals received from the first pressure sensors and the second pressure sensors. With the range hook, the pressure sensors are mounted on the front sides and the back sides of the blades of the auxiliary fans, and the main controller adjusts the revolving speeds of the motors of the auxiliary fans according to signals of the pressure sensors on the two sides, so that the auxiliary fans are automatically matched with the main fan of the range hood, the total air volume is kept at a value or above at which smoke can be exhausted normally, and the smoke suction effect is effectively improved. Besides, with an air volume control method of the range hood, the air volume can be adjusted very conveniently, and the adjusting effect is good.
Description
technical field [0001] The invention relates to a range hood, in particular to a range hood with air volume adjustment and an air volume control method thereof. Background technique [0002] In the public flue, the opening and closing of range hoods of other users will affect the outlet resistance, which will cause the actual flow rate of the range hood on the user side to change continuously, and even the phenomenon that the smoke cannot be exhausted. At present, the motor speed of many range hoods has a small variation range, which cannot cope with the strict outlet regulation, which makes the user feel that the range hood effect is poor when using it. At present, various range hoods with air volume adjustment are disclosed in the prior art, such as "A Oil Suction Range Hood with Air Volume Adjustment Function" disclosed in the Chinese invention patent No. ZL 201310273983.1 (authorized announcement number is CN 103353136 B). Smoke machine and its control system and contro...
