[0057] The flue internal monitoring component 6 is connected to the inside of the flue 2 .

[0058] The temperature online monitoring component 7 is connected to the smoke hood 1 and the inside of the smoke duct 2 .

[0059] The oil fume emission online monitoring component 8 is connected to the flue 2 and is arranged behind the oil fume purification component 3 .

[0060] The remote transceiver component 9 is connected to the flue internal monitoring component 6, the temperature online monitoring component 7 and the oil fume emission online monitoring component 8, and is connected to the user's mobile phone via the network or Bluetooth.

[0061] Among them, the smoke exhaust fan 4 can provide negative pressure in the flue 2, so that the oil fume generated in the oil fume kitchen is sucked from the fume hood 1. The sucked oil fume passes through the fume hood 1 and the flue 2 in turn, and is finally discharged after being purified by the oil fume purification component 3. The oil fume purification component 3 can be an electrostatic purifier. The electrostatic purifier is a prior art, so it is not described in detail in this embodiment. The cleaning modes of the steam cleaning component may include a hot water cleaning mode, a cleaning liquid cleaning mode, a steam mode, and a cold water mode. Each mode may be controlled automatically or manually. In manual control, a cleaning mode is set each time. In the hot water cleaning mode, the oil fume pipe can be cleaned directly by 100°C hot water. In the cleaning liquid cleaning mode, the cleaning can be performed by spraying the cleaning liquid. In the steam mode, high-temperature steam can be sprayed inside the oil fume pipe. In the cold water mode, cold water can be sprayed directly inside the oil fume pipe. In automatic control, the time can be set by a timer so that the steam cleaning component 5 uses a preset cleaning mode to clean for a period of time at a preset time. For example, first start the cleaning liquid cleaning mode to spray the cleaning liquid inside the oil fume pipe, then spray steam inside the oil fume pipe through the steam cleaning mode, and finally clean the inner wall of the oil fume pipe through the hot water mode. The internal monitoring component 6 of the flue can be a camera set in the flue 2. The internal monitoring component 6 of the flue can observe the accumulation of oil scale inside the flue 2 in real time. The online temperature monitoring component 8 can detect the temperature inside the hood 1 and the flue 2 in real time to prevent the excessive temperature from igniting the oil scale inside the oil fume pipe. The oil fume emission online monitoring component 9 can detect emission indicators such as oil fume concentration and emission rate emitted from the flue 2 in real time to avoid excessive emission of oil fume. The remote transceiver component 9 can transmit the monitoring screen in the flue, the temperature in the oil fume pipe and the relevant data of oil fume emission to the mobile phone or display, so that the user can grasp the status of the oil fume pipe in real time.

[0062] The range hood with steam cleaning and online monitoring functions provided in this embodiment has the following beneficial effects:
