For the technical scheme that the first purification module 21 and the second purification module 22 are both arranged outside the smoke machine main body 1, optionally, the two purification modules are respectively arranged on two opposite sides of the fan cover 11 and are both arranged above the smoke collecting hood 12; it can be understood that when the left burner is used for cooking, the oil smoke is easy to escape upwards from the left side of the smoke collecting hood 12, and the first purifying module 21 can better purify the part of the escaped oil smoke; when the right burner is used for cooking, the oil smoke is easy to escape upwards from the right side of the smoke collecting hood 12, and the second purifying module 22 can better purify the part of the escaped oil smoke.
Optionally, for any one of the first purification module 21 and the second purification module 22, the air inlet 201 is arranged on the side facing away from the other. Therefore, the smoke escaping upwards from the corresponding side of the cigarette machine main body 1 is sucked and purified by the corresponding purification module. Specifically, the air inlet 201 of the first purification module 21 located at the left side is arranged at the left side surface thereof, so that the air inlet 201 thereof is closest to the left space of the fume collecting hood 12, and thus when the oil smoke escapes from the left space of the fume collecting hood 12 upwards, the first purification module 21 can suck the escaped oil smoke fast and in a large amount, and the purification efficiency of the first purification module 21 is improved; similarly, the air inlet 201 of the second purification module 22 located at the right side is provided at the right side surface thereof, so that the air inlet 201 thereof is closest to the right space of the fume collecting hood 12, so that when the oil smoke escapes from the right space of the fume collecting hood 12 upwards, the second purification module 22 can suck the escaped oil smoke fast and in a large amount, and the purification efficiency of the second purification module 22 is improved.

It can be understood that when the left burner is used for cooking, the oil smoke is easy to escape upwards from the left side of the smoke collecting hood 12, and the first oil smoke sensor 41 can better acquire the concentration of the oil smoke leaking out from the left side of the smoke collecting hood 12; when the right burner is used for cooking, the oil smoke is easy to escape upwards from the right side of the smoke collecting hood 12, and the second oil smoke sensor 42 can better acquire the concentration of the oil smoke leaked from the right side of the smoke collecting hood 12.
Optionally, for any purification module, the air outlet 202 is disposed on the top surface, so that it will be blown upward or at least have upward blowing component. It can be understood that due to the effect of the thermal plume in the cooking process, the oil smoke is often gathered at the upper half part of the kitchen space, the upward air outlet is favorable for blowing the purified air to the upper half part of the kitchen space, so that the oil smoke at the upper half part of the kitchen space flows downwards under the pushing of the upward blowing purified air through the purified air, the air circulation purification in the kitchen is realized, the oil smoke in the kitchen can be further reduced, and the pollution of the oil smoke to the air environment and the damage to the human health are further reduced.
However, the design is not limited thereto, and in other embodiments, for any purification module, the air outlet 202 may also be disposed on the front surface, so that the air is blown forward or at least has a forward blowing component. In the cooking process, a user usually stands in front of the range hood, and the space in front of the range hood can be defined as a user breathing zone. It can be understood that the forward air outlet is favorable for conveying the purified air to the user breathing area, thereby being favorable for improving the air quality of the user breathing area, reducing the probability of the user sucking the oil smoke and reducing the damage of the oil smoke to the health of the user.
Optionally, for any purification module, the air outlet direction of the air outlet 202 is adjustable, so that the air outlet 202 arranged on the top surface can change the circulation path in the air circulation purification process by changing the air outlet direction, so as to realize air circulation purification of different circulation paths.
Optionally, the air outlet 202 is provided with an air outlet grille to prevent the foreign matters from falling into the corresponding purification module from the air outlet 202. Further optionally, the air outlet grille includes a rotatably disposed air guiding grid to adjust the air outlet direction of the air outlet 202 by rotating the air guiding grid, and the air outlet direction of the air outlet 202 is continuously adjustable. However, the design is not limited thereto, in other embodiments, a plurality of air outlet grills with fixed air guiding grills may be configured, and the air guiding grills of different air outlet grills have different inclination angles with the horizontal plane, and the air outlet grille with the corresponding inclination angle air guiding grills is selected to be installed on the air outlet 202 according to the requirement of the air outlet direction, so that the air outlet direction of the air outlet 202 can be changed by replacing different air outlet grills.
It should be noted that, for the rotatable air guiding grid, the air guiding grid is usually rotated to a position perpendicular to the horizontal plane, that is, the adjustable inclination angle is 90 degrees, so as to vertically exhaust air upwards, which is beneficial to increasing the air exhaust distance, and is more beneficial to realizing air circulation purification in a kitchen. Similarly, for the air outlet grille 25 with a plurality of fixed air guiding bars, an air outlet grille with an inclination angle of 90 ° between the air guiding bars and the horizontal plane is usually selected to be installed to the air outlet 202.
In an embodiment, after the power line of the range hood is connected to the mains supply, the controller 3 determines the starting requirement of the first purification module 21 according to the first oil smoke concentration, and determines the starting requirement of the second purification module 22 according to the second oil smoke concentration, so as to control the first purification module 21 and/or the second purification module 22 to be automatically started when each purification module has the starting requirement.
For example, when the first oil smoke concentration is not less than the first preset concentration, it may be determined that a large amount of oil smoke escapes upwards from the left side of the range hood, generally because the user cooks with the left burner, at this time, the controller 3 controls the first purification module 21 to be turned on, so as to purify the escaped oil smoke in the left area of the range hood by using the first purification module 21 located on the left side, so as to improve the air quality in the left area of the range hood.
For another example, when the second oil smoke concentration is not less than the second preset concentration, it may be determined that a large amount of oil smoke escapes upwards from the right side of the range hood, generally because the user cooks with the right burner, at this time, the controller 3 controls the second purification module 22 to be turned on, so as to purify the escaped oil smoke in the right area of the range hood by using the second purification module 22 located on the right side, so as to improve the air quality in the right area of the range hood.
For another example, when the first oil smoke concentration is not less than the first preset concentration and the second oil smoke concentration is not less than the second preset concentration, it may be determined that a large amount of oil smoke escapes upwards from both the left side and the right side of the range hood, generally because a user cooks with the left burner and the right burner at the same time, at this time, the controller 3 controls both the first purification module 21 and the second purification module 22 to be turned on, so as to improve the air quality of the left area and the right area of the range hood at the same time.
During cooking, edible oil and food undergo a series of chemical reactions such as oxidation, cracking and polymerization at high temperature, a large amount of organic smoke is evaporated, and partial decomposition products are emitted into air in the form of oil mist to form oil smoke. The oil fume includes both edible oil and its heating decomposition or cracking product and also includes the physical and chemical reaction product of protein, polymer compound and various seasoning matters in food, and is one kind of matter containing gas, liquid and solid. Generally, the Particulate Matter Emission (PME) composed of liquid and solid in the oil smoke emission is defined as PME, and the Volatile Organic Compounds emission (VOCs) is defined as VOCs, and the oil smoke is composed of the above two substances. Based on this, the soot concentration can be characterized by the particulate matter concentration and/or the odor concentration.
In one embodiment, the first soot sensor 41 only includes a first particulate matter sensor, so as to detect a first particulate matter concentration to determine the air quality of the location. It can be understood that in the present embodiment, in the process of controlling the operating state of the first purification module 21 according to the first soot concentration, the judgment and control are performed according to the first particulate matter concentration, and accordingly, the first preset concentration in the foregoing embodiment corresponds to a first preset particulate matter concentration. For example: when the first soot sensor 41 only includes the first particulate sensor, the first predetermined particulate concentration is 75.0 μ g/m3That is, when the first particulate matter sensor detects the measured first particulate matter concentration of not less than 75.0 μ g/m3At this time, the controller 3 controls the first purification module 21 to be turned on.
However, the design is not limited thereto, and in other embodiments, the first soot sensor 41 may further include only the first odor sensor to detect the first odor concentration to determine the air quality at the position. It can be understood that in the present embodiment, in the process of controlling the working state of the first purification module 21 according to the first oil smoke concentration, the judgment and control are performed according to the first odor concentration, and accordingly, the first preset concentration in the foregoing embodiment corresponds to a first preset odor concentration. For example: when the first soot sensor 41 only includes the first odor sensor, the first preset odor concentration is 0.6mg/m3That is, when the first odor sensor detects the first odor concentration measured is not less than 0.6mg/m3At this time, the controller 3 controls the first purification module 21 to be turned on.
