Problems solved by technology

[0003] However, the current range hoods only have the function of absorbing oil fume, but not the function of separating oil fume. Long-term use will easily cover the wind wheel with thick oil fume, resulting in restricted rotation of the wind wheel and seriously affecting the service life of the range hood.
On the other hand, most of the current range hoods cannot automatically sense the concentration of oil fume, and cannot automatically adjust the suction power of oil fume according to the concentration of oil fume.

Embodiment 1

[0034] Such as figure 1 As shown, this embodiment provides an intelligent range hood, which includes a wind wheel 1 , an oil fume separation device 2 and a real-time oil fume monitoring and control system 3 .

[0035] The oil fume separation device 2 is installed under the wind wheel 1 to separate the oil fume; the oil fume real-time monitoring and control system 3 is installed around the oil fume separation device 2 to detect the concentration of oil fume in real time and adjust the speed of the wind wheel 1 and the oil fume separation device according to the concentration of oil fume 2. The speed of separating oil fumes.

[0036] The oil fume real-time monitoring and control system 3 includes an oil fume sensing device 31 and a control device 32;

[0037] The oil fume sensing device 31 is connected with the control device 32 for signals;

[0038] The soot sensing device 31 is used to detect the concentration of soot and send the measured soot concentration data to the cont...

Embodiment 2

[0046] The other features of the intelligent range hood provided in this embodiment are the same as those in Embodiment 1, except that the oil fume sensing device 31 is set as one or more sensors for detecting the concentration of oil fume and one or more sensors for collecting Combination of cameras for oil fume images; wherein, the camera sends the collected oil fume images to the control device 32, and the control device 32 analyzes the oil fume images to obtain the oil fume concentration.

[0047] The oil fume sensing device 31 of the intelligent range hood in this embodiment is configured as a combination of a sensor and a camera. When working, the sensor detects the oil fume concentration around the range hood and sends the detected oil fume concentration to the control device 32, and the camera sends the collected oil fume image to the control device 32, and the control device 32 obtains the oil fume concentration according to the analysis of the oil fume image. Finally...

Embodiment 3

[0050] Such as figure 2 As shown, a smart range hood provided in this embodiment has the same other features as in Embodiment 2, except that the control device 32 is also provided with a teaching pendant 323, and the teaching pendant 323 controls the artificially adjusted wind wheel 1 The rotational speed, the oil fume separation speed and the corresponding oil fume concentration are stored; the control device 32 is also used to match the received oil fume concentration with the oil fume concentration stored in the teaching pendant 323, the speed of the wind wheel 1 and the oil fume separation speed, and according to the matching result Adjust the rotation speed of wind wheel 1 and the oil fume separation speed.

[0051]The control device 32 of the intelligent range hood in this embodiment is also provided with a teach pendant 323. Before the range hood realizes intelligent control, artificial teaching is performed, and the set speed of the wind wheel 1 and the oil fume separ...

Abstract

The invention provides an intelligent exhaust hood which comprises a wind wheel, an oil fume separating device and an oil fume real-time monitoring control system, wherein the oil fume separating device is arranged below the wind wheel and used for separating oil fume; and the oil fume real-time monitoring control system is arranged around the oil fume separating device, and used for detecting theconcentration of the oil fume as well as regulating the rotating speed of the wind wheel and the oil fume separating speed of the oil fume separating device according to the concentration of the oilfume. According to the intelligent exhaust hood, the adsorbed oil fume is separated through a combination of centrifugal force and suction force, so that the accumulation of the oil fume in the intelligent exhaust hood can be effectively reduced and the influence of the accumulation of the oil fume on the service life of the intelligent exhaust hood can be prevented; and besides, the concentrationof the oil fume around the intelligent exhaust hood can be detected in real time, and the centrifugal force and the suction force can be correspondingly regulated according to the detected concentration of the oil fume, thereby achieving the intelligent control over the rotating speed of the wind wheel and the rotating speed of the oil fume separating device.

Description

technical field [0001] The invention relates to the technical field of kitchen range hoods, in particular to an intelligent range hood. Background technique [0002] Range hoods have been widely used in thousands of households. Range hoods can effectively absorb and discharge cooking fumes and purify the kitchen environment. Its main working principle is: connect the power supply of the range hood, drive the motor to make the wind wheel rotate at a high speed, form a negative pressure area in a certain space above the stove, and then suck the indoor fumes into the range hood. [0003] However, the current range hoods only have the function of absorbing oil fume, but not the function of separating oil fume. Long-term use will easily cover the wind wheel with thick oil fume, resulting in restricted rotation of the wind wheel and seriously affecting the service life of the range hood. . On the other hand, most of the current range hoods cannot automatically sense the concentr...
