Wherein, the air exhaust duct 11 is arranged in a herringbone shape, and a left air inlet cavity 111 and a right air inlet cavity 112 are formed therein, and the air outlet of the left air inlet cavity 111 and the right air inlet cavity 112 end and form an air outlet cavity 113, the air inlet cavity 211 communicates with the air outlet cavity 113; the exhaust fan 14 includes a Cooperate with the left exhaust fan 14 and the right exhaust fan 14, the check valve 15 includes a left check valve 15 and a right check valve respectively arranged at the air outlet ends of the left air inlet cavity body 111 and the right air inlet cavity body 112 15. Multiple anode cylinders 225 are arranged in a honeycomb shape, and any two adjacent anode cylinders 225 are arranged tangentially.

During specific arrangement, two accommodation cavities are formed in the housing 12, and the left exhaust fan 14 and the right exhaust fan 14 are respectively built in the two accommodation cavities. When the left side of the gas stove is working, the left exhaust fan 14 can be opened To extract the oil fume, the left exhaust fan 14 can be set facing the left stove mouth, so as to ensure the extraction efficiency. Correspondingly, when the right stove mouth is working, the right exhaust fan 14 can be turned on to extract the oil fume. The left exhaust fan 14 and the right exhaust fan 14 Moderate power can be used to avoid energy waste; and when the two stove mouths of the gas range are all working, such as when the left stove mouth is cooking and the right stove mouth is cooking soup, the left exhaust fan 14 and the right exhaust fan 14 can be used Open at the same time to ensure the extraction efficiency of oil fume; and, the two stove mouths of the gas stove of the present embodiment can be used alternately, and the corresponding left exhaust fan 14 and right exhaust fan 14 are used alternately, thereby avoiding damage to a single device for a long time. It is beneficial to prolong the service life of the gas range and the exhaust fan 14.

The oil smoke drawn in enters the air outlet cavity 113. The air outlet cavity 113 of this embodiment is in a vertical state, while the purification flue 21 is in a horizontal state. When the oil fume enters the air intake cavity 211 from the air outlet cavity 113, Due to the change of the airflow direction, the airflow velocity is lower, which is beneficial to improve the follow-up oil fume purification efficiency, and through the effect of the uniform air net 23, it can reduce the flow velocity again and improve the purification efficiency; A left check valve 15 and a right check valve 15 are respectively provided at the air outlet ends of the cavity 111 and the right air inlet cavity 112, which can prevent backflow of oil fumes.

When the oily fume enters the anode cylinder 225, the oily fume combines with the negative charge under the action of the sharp part of the cathode needle 226, and moves toward the inner wall of the anode cylinder 225 to remove the oily fume.

In this embodiment, the cathode needle 226 is fixed on one side, which is beneficial to reduce the blocking effect of the fixing frame 223 on the airflow, and ensure the fluency of the airflow and the effect of removing the oil fume. In order to further reduce the obstruction of the airflow by the fixed frame 223, the fixed frame 223 in this embodiment includes a plurality of regular hexagonal frames 223a arranged in sequence from the inside to the outside and a connecting body 223b connecting two adjacent frames 223a, One end of each cathode needle 226 is matched and fixed on the frame body 223a.

In actual application, due to the relatively slow airflow velocity in the purification mechanism 2, it is easy to cause the oil fume concentration in the exhaust flue 11 to increase, which in turn leads to the inability to fully extract the indoor oil fume.

When the oil fume concentration sensor 31 detects that the oil fume concentration in the air inlet cavity 211 is too large, the exhaust fan 16 can be driven by the controller 32 to open. After the concentration of soot in the air cavity body 211 decreases, the exhaust fan 16 can be driven to stop.

Specifically, the controller 32 in this embodiment includes a soot concentration signal acquisition circuit 321 for collecting the electrical signal generated by the soot concentration sensor 31 to detect the soot concentration, and a second circuit for comparing whether the electrical signal is greater than the first threshold. A comparison circuit 322, a first drive circuit 323 for driving the exhaust fan 16 to rotate when the electrical signal is greater than a first threshold, a second comparison circuit 324 for comparing whether the electrical signal is less than a second threshold, A second drive circuit 325 for driving the exhaust fan 16 to stop rotating when the electrical signal is smaller than a second threshold; wherein the first threshold is smaller than the second threshold. When the oil fume concentration sensor 31 detects that the oil fume concentration in the air intake cavity 211 is higher than the upper limit, the oil fume concentration sensor 31 detects that the electric signal generated by the oil fume concentration is greater than the first threshold value, which will easily cause the indoor oil fume to be unable to be extracted, so through the first The drive circuit 323 drives the exhaust fan 16 to rotate to promote the discharge of oil fume, and when the concentration of oil fume discharged into the air intake cavity 211 is lower than the lower limit value, the electric signal generated by the oil fume concentration sensor 31 detecting the oil fume concentration is less than the second threshold value, in order to To avoid energy waste caused by the rotation of the exhaust fan, the exhaust fan 16 can be driven to stop rotating through the second drive circuit 325 .

Compared with the prior art, the utility model sets the exhaust flue 11 in a herringbone shape, and sets the left exhaust fan 14 and the right exhaust fan 14 to correspond to the two stove mouths respectively, which can realize the pertinence of oil fume extraction, and then The energy consumption is reduced, the extraction efficiency of the oil fume is improved, and at the same time, the purification mechanism 2 is used to purify the oil fume, which improves the removal efficiency of the oil fume.
