The control board 201 is configured to receive the flue pressure detected by the wind pressure sensor 203, the oil smoke concentration obtained by detecting the side surface of the range hood 20 by the smoke sensor 204, and the oil smoke concentration obtained by detecting the oil smoke inlet of the range hood 20 by the infrared sensor 205, and determine a control signal of the fan 207 according to the received flue pressure, the oil smoke concentration of the side surface of the range hood 20, and the flue concentration of the oil smoke inlet of the range hood 20, and send the control signal to the electronic control board 202; the electric control board 202 is configured to control the fan 207 to operate according to a control signal sent by the control board 201, for example, the control board 201 determines, according to the received flue pressure and flue concentration, that the control signal of the fan 207 is to control the fan 207 to switch to a target gear operation, and sends the control signal (to control the fan 207 to switch to the target gear operation) to the electric control board 202; the electric control board 202 controls the fan 207 to switch to the target gear operation according to the control signal sent by the control board 201. As shown in fig. 1, the method specifically may include the following steps:
S101, acquiring first oil smoke concentration of the side face of the smoke ventilator detected by the smoke sensor in preset time, and acquiring second oil smoke concentration of the oil smoke air inlet of the smoke ventilator detected by the infrared light sensor in preset time.
The preset time is understood to be a preset time length.
For example, the smoke sensor 204 in fig. 2 may detect a first smoke concentration of a side surface of the smoke ventilator within a preset time, and the infrared sensor 205 may detect a second smoke concentration of a smoke inlet of the smoke ventilator within the preset time; then, the first oil smoke concentration of the side face of the range hood detected by the smoke sensor 204 in the preset time is obtained, and the second oil smoke concentration of the oil smoke air inlet of the range hood detected by the infrared light sensor 205 in the preset time is obtained, wherein the first oil smoke concentration is 1.7 ppm.
S102, determining the target oil smoke concentration of the range hood based on the first oil smoke concentration and the second oil smoke concentration.
The target oil smoke concentration can be understood as the oil smoke concentration detected by different sensors belonging to the same preset oil smoke concentration interval. The preset oil smoke concentration interval can be understood as a numerical value interval where the preset oil smoke concentration is located, and the preset oil smoke concentration interval can be multiple. In this embodiment, the target oil smoke concentration may be understood as a first oil smoke concentration of a side surface of the range hood detected by the oil smoke sensor belonging to the same preset oil smoke concentration range or a second oil smoke concentration of an oil smoke air inlet of the range hood detected by the infrared light sensor. The oil smoke concentrations detected by different sensors in the preset time are obtained, so that the oil smoke concentration detection device can comprise a plurality of first oil smoke concentrations and a plurality of second oil smoke concentrations.
In general, the smoke sensor is used for detecting the concentration of the oil smoke, the detection speed is low, but the detection accuracy of the concentration of the oil smoke is high; the infrared light sensor is used for detecting the oil smoke concentration, the detection speed is high, but the detection accuracy of the oil smoke concentration is low. The first oil smoke concentration detected by the smoke sensor and the second oil smoke concentration detected by the infrared light sensor are obtained simultaneously within the preset time, and as the detection accuracy of the second oil smoke concentration of the infrared light sensor is lower than that of the first oil smoke concentration detected by the smoke sensor, if the first average oil smoke concentration of the plurality of first oil smoke concentrations and the second average oil smoke concentration of the plurality of second oil smoke concentrations belong to the same preset oil smoke concentration interval, the oil smoke concentration of the side face of the smoke ventilator and the oil smoke concentration of the air inlet can be more accurately determined, the first average oil smoke concentration or the second average oil smoke concentration can be more accurately determined to be the target oil smoke concentration, further, the accuracy of determining the target oil smoke concentration is improved, the situation that a user determines the oil smoke concentration of the side face of the smoke ventilator and the oil smoke concentration of the air inlet to be the same in size according to experience is avoided, the fan is switched to an unsuitable gear is further solved, the problem that the fan is relatively poor in effect and the fan is switched to a relatively high-power consumption range.
In an alternative embodiment, whether the first average oil smoke concentration or the second average oil smoke concentration is the target oil smoke concentration may be determined by determining whether a first average oil smoke concentration of the plurality of first oil smoke concentrations over a preset time and a second average oil smoke concentration of the plurality of second oil smoke concentrations over the preset time are within the same preset oil smoke concentration interval.
For example, if the first oil smoke concentrations are respectively: 1.7ppm, 1.6ppm, 1.8ppm, 1.6ppm, respectively, of the second oil smoke: 1.7ppm, 1.9ppm, 1.8ppm and 1.7ppm, wherein the number of preset oil smoke concentration intervals is 2, namely [ 0,1.5 ] and [ 1.6,3.0 ], the first average oil smoke concentration of the first oil smoke concentrations can be determined to be 1.675ppm, the second average oil smoke concentration of the second oil smoke concentrations can be determined to be 1.775ppm, the first average oil smoke concentration and the second average oil smoke concentration belong to the same preset oil smoke concentration interval [ 1.6,3.0 ], and the first oil smoke concentration of 1.675ppm or the second oil smoke concentration of 1.775ppm can be determined to be the target oil smoke concentration.
S103, acquiring the first flue pressure of the smoke exhaust ventilator.
The first flue pressure is understood to be the first detected flue pressure of the exhaust flue.
For example, the flue pressure of the exhaust stack may be detected by the wind pressure sensor 203 in fig. 2, and then the flue pressure S of the exhaust stack detected by the wind pressure sensor 203 may be obtained.
And S104, determining a target gear to be switched by the fan based on the target oil smoke concentration and the first flue pressure.
The gear of the fan can comprise a high-speed gear, a medium-speed gear and a low-speed gear; the target gear may be understood as a gear to be switched by the fan, and in this embodiment, the target gear to be switched by the fan may include a low gear, a medium gear, and a high gear.
In general, if the flue concentration becomes smaller, the gear of the fan needs to be reduced; the flue pressure becomes large, which indicates that the gear of the fan needs to be raised, but if the fan is in a higher gear running state for a long time, larger noise is generated and extra electric energy is consumed.
Therefore, when the flue concentration and the flue pressure change, the fan is controlled to be switched to a proper target gear. In order to avoid the problems of poor smoking effect of the smoke ventilator and poor use experience of a user caused by switching the fan to an unsuitable gear, the fan can be controlled to be switched to the middle-speed gear when the flue concentration belongs to a preset flue concentration interval switched to the middle-speed gear of the fan and the flue pressure belongs to a preset pressure interval switched to the middle-speed gear of the fan; when the flue concentration belongs to a preset flue concentration interval switched to a low-speed gear of the fan and the flue pressure belongs to a preset pressure interval switched to the low-speed gear of the fan, the fan is controlled to be switched to the low-speed gear, so that the target gear to be switched by the fan can be accurately and flexibly determined according to the flue concentration and the flue pressure, the problems that the smoke exhaust ventilator generates larger noise and consumes additional electric quantity due to larger air quantity corresponding to the gear switched by the fan because of smaller smoke exhaust concentration and smaller flue pressure are solved, the problem that the smoke exhaust effect of the smoke exhaust ventilator is poor due to smaller air quantity corresponding to the gear switched by the fan because of larger smoke exhaust concentration and larger flue pressure is solved, the intelligence of the smoke exhaust ventilator is improved, and better use experience is brought to a user.
Thus, in an alternative embodiment, a first preset condition that the target oil smoke concentration meets may be determined according to the preset flue concentration, and a second preset condition that the first flue pressure meets may be determined according to the preset pressure; and determining a target gear to be switched by the fan according to the first preset condition and the second preset condition. The preset flue concentration may be understood as a preset flue concentration threshold, and the preset flue concentration may include a plurality of flue concentrations. The first preset condition may include a first low-speed gear condition, a first medium-speed gear condition, and a first high-speed gear condition, the first low-speed gear condition may be understood as a condition that the flue concentration satisfies the switching of the fan gear to the low-speed gear, the first medium-speed gear condition may be understood as a condition that the flue concentration satisfies the switching of the fan gear to the medium-speed gear, and the first high-speed gear condition may be understood as a condition that the flue concentration satisfies the switching of the fan gear to the medium-speed gear. The second preset condition may include a second low-speed gear condition, a second medium-speed gear condition, and a second high-speed gear condition, the second low-speed gear condition may be understood as a condition that the first flue pressure satisfies the switching of the fan gear to the low-speed gear, the second medium-speed gear condition may be understood as a condition that the first flue pressure satisfies the switching of the fan gear to the medium-speed gear, and the third medium-speed gear condition may be understood as a condition that the first flue pressure satisfies the switching of the fan gear to the medium-speed gear.
Specifically, a first preset condition met by the target oil smoke concentration can be determined according to the preset flue concentration, and a second preset condition met by the first flue pressure is determined according to the preset pressure, so that a target gear to be switched by the fan is determined. If the first low-speed gear condition and the second low-speed gear condition are met at the same time, determining that the target gear to be switched by the fan is the low-speed gear; if the first medium speed gear condition and the second medium speed gear condition are met at the same time, determining that the target gear to be switched by the fan is the medium speed gear; if the first high gear condition and the second high gear condition are satisfied at the same time, it may be determined that the target gear to be switched by the fan is the high gear.
For example, if the first preset flue concentration may be 1.6Ppm, the first preset pressure is 400Pa, the target oil smoke concentration is 1.5Ppm, the first flue pressure is 300Pa, and the condition that the flue concentration satisfies the condition of switching the fan gear to the low-speed gear is assumed to be: the flue concentration does not exceed a first preset flue concentration; the flue pressure satisfies the condition of switching fan gear to low-speed gear: the first flue pressure does not exceed a first preset pressure. The target oil smoke concentration can be determined to meet the first low-speed gear condition in the first preset condition according to the preset flue concentration, and the first flue pressure is determined to meet the second low-speed gear condition in the second preset condition according to the preset pressure, namely, the first low-speed gear condition and the second low-speed gear condition are met at the same time, so that the target gear to be switched by the fan can be determined to be the low-speed gear.
S105, controlling the fan to switch to a target gear to operate, so that the fan generates wind speed corresponding to the target gear.
In this embodiment, based on the first oil smoke concentration detected by the smoke sensor and the second oil smoke concentration detected by the infrared light sensor, the target oil smoke concentrations of the side face and the air inlet of the smoke ventilator are determined more accurately, the problem that the oil smoke concentrations determined by the user according to experience are inaccurate is solved, the proper target gear to be switched by the fan is determined more accurately and flexibly by combining the target oil smoke concentrations and the first flue pressure, the problem that the smoke exhausting effect of the smoke ventilator is poor due to the fact that the fan is switched to the lower gear is solved, the problem that the smoke exhausting effect of the smoke ventilator is poor due to the fact that the fan is switched to the higher gear is solved, the problem that the smoke ventilator generates larger noise and consumes additional electric quantity is solved, the purpose that noise generated by the smoke ventilator is reduced and electric energy is saved is achieved, the fan is controlled to operate at the proper target gear, so that the fan generates wind speed corresponding to the target gear is improved, smoke exhausting efficiency of the smoke ventilator is improved, smoke exhausting effect of the smoke ventilator is better, and better using experience of the smoke ventilator is brought to the user.
Fig. 3 is another flow chart of a method for adjusting wind speed of a range hood according to an embodiment of the present invention, and a specific method may be shown in fig. 3, and the method may include the following steps:
S301, acquiring first oil smoke concentration of the side face of the smoke ventilator detected by the smoke sensor in preset time, and acquiring second oil smoke concentration of the oil smoke air inlet of the smoke ventilator detected by the infrared light sensor in preset time.
S302, determining a first average oil smoke concentration according to the first detection times and the first oil smoke concentration in the preset time, and determining a second average oil smoke concentration according to the second detection times and the second oil smoke concentration in the preset time.
The first detection times can be understood as times of detecting the first oil smoke concentration in a preset time; the second detection frequency can be understood as the frequency of detecting the second oil smoke concentration within the preset time.
In an alternative embodiment, the first average oil smoke concentration may be calculated according to the plurality of first oil smoke concentrations and the first detection times of the first oil smoke concentration within the preset time; the second average oil smoke concentration may be calculated according to the plurality of second oil smoke concentrations and the second detection times of the second oil smoke concentrations within the preset time.
For example, if the first oil smoke concentrations are respectively: 1.7ppm, 1.6ppm, 1.8ppm and 1.6ppm, and the detection times of the first oil smoke concentration in the preset time is 4, the first oil smoke concentrations and the detection times can be substituted into a calculation formula of the average oil smoke concentration for calculation, so that the first average oil smoke concentration is 1.675ppm.
The calculation formula of the average oil smoke concentration is as follows:
average soot concentration= (x1+x2+ … … +xn)/number of detections.
Wherein xn may be expressed as the nth first soot concentration.
The calculation method of the second average oil smoke concentration may refer to the calculation method of the first average oil smoke concentration, and will not be described again.
S303, when the first average oil smoke concentration and the second average oil smoke concentration both belong to the same preset oil smoke concentration interval, determining the first average oil smoke concentration or the second oil smoke concentration as the target oil smoke concentration.
S304, determining a first preset condition met by the target oil smoke concentration according to the preset flue concentration, and determining a second preset condition met by the first flue pressure according to the preset pressure.
The preset flue concentration comprises a first preset flue concentration, a second preset flue concentration and a third preset flue concentration, wherein the first preset flue concentration is smaller than the second preset flue concentration, and the second preset flue concentration is smaller than the third preset flue concentration. The preset pressures may include a first preset pressure and a second preset pressure, the first preset pressure being less than the second preset pressure.
In an alternative embodiment, the fan is controlled to switch to the low gear when the target stack concentration belongs to a preset stack concentration interval for switching to the low gear of the fan and the first stack pressure belongs to a preset pressure interval for switching to the low gear of the fan.
The preset flue concentration interval switched to the low-speed gear of the fan can be understood as a flue concentration interval formed by 0ppm and the first preset flue concentration, so that when the target oil smoke concentration does not exceed the first preset flue concentration, the target flue concentration is determined to belong to the preset flue concentration interval switched to the low-speed gear of the fan, namely, the target oil smoke concentration meets the first low-speed gear condition. The preset pressure interval for switching to the low speed gear of the fan can be understood as a flue pressure interval formed by 0Pa and a first preset flue pressure. Therefore, when the first flue pressure does not exceed the first preset pressure, it is determined that the first flue pressure belongs to a preset pressure interval for switching to the fan low-speed gear, that is, the first flue pressure meets the second low-speed gear condition.

For example, as shown in fig. 4, when the fan is operated at the 1 st gear, the second flue pressure is 600Pa,500Pa <600Pa, that is, the second flue pressure exceeds the second preset pressure (500 Pa), so that the fan can be controlled to be switched to be operated at the high-speed gear.
When the fan is operated in the 1 gear, the second flue pressure is 400Pa,300Pa <400Pa <500Pa, namely, the second flue pressure exceeds the first preset pressure (300 Pa), the second flue pressure does not exceed the second preset pressure (500 Pa), and the target gear is a low-speed gear, so that the fan can be controlled to be increased and switched to the 2-gear operation of the fan.

When the fan 2 runs, the second flue pressure is 700Pa,500Pa <700Pa, namely the second flue pressure exceeds the second preset pressure (500 Pa), and the fan can be controlled to rise and switch to the fan 3 runs.
