[0040] In addition, in this specific embodiment, if the connection or fixing method between components is not specifically described, the connection or fixing method can be through bolt fixing or pin fixing, or pin shaft connection and the like commonly used in the prior art, and therefore, it is not described in detail in this embodiment.

[0041] like Figure 1-3 As shown, a range hood comprises: a base 1, a cleaning component 5 and an air duct system 2. The base 1 is provided with an oil fume sensor 3 for real-time detection of oil fume concentration. The base 1 is provided with a surrounding plate 4, and the air duct system 2 is arranged in the surrounding plate 4.

[0042] like Figure 4-6As shown, the cleaning component 5 includes a solvent box 51, a nozzle 52, an air inlet nozzle 53, and a gas-liquid mixing pump 54. The solvent box 51 is arranged on the base 1, and the solvent box 51 is connected to the gas-liquid mixing pump 54. The air inlet nozzle 53 is arranged on the side of the enclosure 4, the air inlet nozzle 53 is connected to the gas-liquid mixing pump 54, and the nozzle 52 is connected to the air duct system 2; the gas-liquid mixing pump 54 can extract gas and liquid at the same time, the solvent box 51 is filled with a detergent for cleaning, the solvent box 51 is fixed to the base 1 by screws, and the solvent box 51 is connected to the gas-liquid mixing pump 54 through a silicone hose; the air channel of the air inlet nozzle 53 connects the inside and outside of the enclosure 4, the inlet of the air channel is located outside the enclosure 4, and the outlet of the air channel is located inside the enclosure 4 and is connected to the gas-liquid mixing pump 54 through a silicone hose, to ensure that the gas extracted by the gas-liquid mixing pump 54 when it is working is clean gas outside the range hood, to avoid failure of the gas-liquid mixing pump 54 due to inhalation of oil smoke.

[0043] like Figure 4 As shown, a liquid level sensor 511 is disposed on the outer surface of the solvent box 51 , and the liquid level sensor 511 is a capacitive sensor for detecting liquid capacity.

[0044] like Figure 5-6 As shown, the nozzle 52 is provided with a leakage hole 521 . When the nozzle 52 is installed with the air duct system 2 , the leakage hole 521 needs to be downward to facilitate subsequent foam to flow downward into the air duct system 2 .

[0045] like Figure 7-8 As shown, a range hood cleaning method comprises:

[0046] Start the range hood, set the oil pollution threshold Qs and the liquid volume threshold V0, calculate the oil pollution value Q through the oil smoke sensor 3, and record the oil pollution value Q, and judge the oil pollution in the range hood according to the oil pollution value Q;

[0047] Determine the values ​​of the oil pollution value Q and the oil pollution threshold Qs. When the oil pollution value Q is less than the oil pollution threshold Qs, continue to calculate the oil pollution value Q.

[0048] When the oil pollution value Q is greater than or equal to the oil pollution threshold value Qs, the range hood is reminded to be cleaned and the cleaning component enters the waiting state, and then the liquid volume V in the solvent box 51 is detected and calculated by the liquid level sensor 511;

[0049] Determine the value of the liquid volume V and the liquid volume threshold V0, and when the liquid volume V is less than the liquid volume threshold V0, remind the user to add liquid to the solvent box 51, and then re-detect and calculate the liquid volume V of the solvent box 51;

[0050] When it is detected that the liquid volume V is greater than or equal to the liquid volume threshold V0, the cleaning component 5 is started to clean the range hood.

[0051] The cleaning steps of the cleaning component 5 include:

[0052] First, the gas-liquid mixing pump 54 and the motor start working. The gas-liquid mixing pump 54 extracts gas and liquid at the same time, and the motor drives the wind wheel to operate at a constant low speed. During this period, the gas and liquid are mixed in the gas-liquid mixing pump 54 and converted into foam. At the same time, the gas-liquid mixing pump 54 sprays foam to the wind wheel, and the foam flows downward through the discharge hole 521 connected to the nozzle 52 through the hose, and covers the wind wheel as the wind wheel rotates continuously;

[0053] Then, after working for T1 time, the gas-liquid mixing pump 54 is turned off, and the motor continues to operate at a low speed for T2 time, during which the foam adheres to the wind wheel to clean the wind wheel;

[0054] Afterwards, after the wind wheel is cleaned, the motor runs at high speed for T3 time, during which the foam and oil on the wind wheel are thrown away from the wind wheel;

[0055] Finally, after cleaning is completed, the range hood can be turned off, the timer is reset to zero, and the oil pollution value Q is reset to zero. The oil pollution value Q will be recalculated at the next startup.

[0056] The above cleaning method can be started based on the actual usage of the user. By corresponding different amounts of oil smoke to different time periods, the internal oil smoke pollution level can be ensured to the greatest extent, solving the problem of different oil pollution values ​​determined by time.

[0057] In this embodiment, the low-speed operation is 40-90 r / min, the high-speed operation is 500-1200 r / min, the T1 duration is 30-90 s, the T2 duration is 1-10 min, and the T3 duration is 10-60 s.

[0058] like Figure 7 As shown, the oil pollution value Q = c 0 T+c 1 T+c 2 T+…+c n T, when T is smaller, the formula of oil pollution value Q can be obtained, the formula is In this embodiment, T is the sampling period, c is the oil fume concentration, where C is the oil fume concentration, tn is the working time, dt is the differential of time, that is, a tiny time, and Q represents the oil pollution value accumulated in tn time.

[0059] The technical effects of the present invention are mainly reflected in the following aspects:

[0060] It is started based on the actual usage of the users, and different oil fume amounts correspond to different time periods, which can ensure the same internal oil fume pollution level to the greatest extent, and solve the problem of different oil pollution values ​​determined by duration.

[0061] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
