Referring to fig. 2, the present embodiment further provides a control method of a range hood, where the control method includes the following steps:
s1, starting the fan 1 of the range hood;
s2, judging whether the target object exists in the preset range, if so, turning to the next step, otherwise, continuing to execute the step S2;
specifically, in this embodiment, the target object is taken as a portable smart device, the portable smart device is preferably a smart phone with a specific tag, the obtaining module 2 corresponds to a communication module integrated on the cigarette making machine body, and the communication module is in wireless communication connection with the smart phone.
After the fan 1 is started, the communication module of the range hood is controlled to send out a detection signal, if a user carries a smart phone with a specific label to be close to the range hood, the smart phone and the communication module of the range hood generate induction, the communication module detects that the user carries the smart phone with the specific label at the moment, the target object is shown to be present in a preset range, the condition of entering a noise regulation mode of the range hood is met at the moment, and then the next step is carried out.

In this embodiment, referring to fig. 3, the preset range is centered on the range hood, and the communication module can detect the maximum range of the smartphone. In particular, before entering the noise regulation mode of the range hood, the range hood controls the fan 1 to operate in a normal operation mode. The normal working mode can be the wind speed gear that the user selected manually, also can carry out self-adaptation for the wind speed gear of fan 1 according to the oil smoke concentration and adjust, and under this mode, the cigarette machine only need compromise the smoking effect, no longer considers the noise that the cigarette machine work produced to user's influence.
S3, entering a noise adjusting mode of the cigarette machine;
s4, acquiring current position information between the range hood and the target object;
specifically, when or after the smart phone and the communication module of the range hood generate induction, the current position information of the smart phone is acquired.
And S5, adjusting the running wind gear of the fan 1 according to the current position information and the preset position information.
Specifically, the current location information includes a current distance and/or a current angle. The preset position information includes a set distance and/or a preset angle. The control module 4 can adjust the operation wind shield of the fan 1 according to the acquired current position information and the pre-stored preset position information, so that the operation wind shield of the fan 1 is associated with the current position information of the user, the noise generated when the cigarette machine operates is adaptively adjusted, the minimum noise generated when the cigarette machine works is ensured, and the comfort level and the experience of the user in using the cigarette machine are improved.
Optionally, in step S5, the operating gear of the wind turbine 1 is adjusted according to the current position information and the preset position information, and the specific adjustment manner includes, but is not limited to, any of the following manners.
In a first adjustment manner, referring to fig. 4, the current position information includes a current distance, which is a linear distance between the range hood and the smart phone. The preset position information includes a set distance. The step of adjusting the operating wind shield of the fan 1 according to the current position information and the preset position information includes:
s511, comparing the current distance with the set distance;
specifically, the set distance includes a maximum set distance and an intermediate set distance smaller than the maximum set distance. The control module 4 compares and analyzes the current distance with the intermediate set distance and the maximum set distance.
And S512, determining the expected operation wind gear of the fan 1 based on the comparison result.
Specifically, the fan 1 of the range hood has at least three gear wind speeds, namely a low gear wind speed, a medium gear wind speed and a high gear wind speed. The low-gear wind speed can only comprise one gear, and can also be finely divided into at least two gears, namely, the lowest-gear wind speed and the lower-gear wind speed. Similarly, the middle wind speed may include one gear, or be subdivided into at least two gears.
If the current distance is less than or equal to the middle set distance, the fact that the distance between the user and the cigarette machine is short is indicated, the user experience is influenced due to the fact that the noise generated by the cigarette machine is large, the fan 1 is controlled to operate according to the low-gear wind speed, the expected operation wind gear is the low-gear wind speed at the moment, the noise generated by the cigarette machine in operation is reduced, when the distance between the user and the cigarette machine is short, the noise generated by the cigarette machine in operation is minimum, the user is in a low-noise environment, and the comfort level and the experience of the user are improved.
If the current distance belongs to the middle set distance and the maximum set distance, which indicates that the distance between the user and the range hood is far, the fan 1 is controlled to operate according to the middle-gear wind speed, and the expected operation wind gear is the middle-gear wind speed at the moment so as to ensure that the range hood has a good smoking effect.
If the current distance is larger than the maximum set distance, the user is far away from the range hood, the fan 1 is controlled to operate according to the high-grade wind speed, and the expected operation wind gear is the high-grade wind speed at the moment, so that the best smoking effect of the range hood is ensured, and the situation that oil smoke escapes during quick frying is prevented. At this time, although the fan 1 operates at a high-grade wind speed with the highest noise, the user is not greatly affected even if the noise is the highest because the user is far away from the range hood.
Further, in order to avoid the situation that the oil smoke escapes due to the small suction force generated by the fan 1 when the fan 1 operates at the low-gear wind speed. The set distance comprises a minimum set distance less than the intermediate set distance. Referring to fig. 4, the step of adjusting the operating gear of the wind turbine 1 according to the current position information and the preset position information may further include:
s501, after the expected operation wind gear of the fan 1 is determined to work, namely after the step S512, judging whether the current distance is smaller than or equal to the minimum set distance, if so, executing an intelligent constant smoking strategy, wherein the intelligent constant smoking strategy is used for enabling the cigarette machine to give consideration to smoking effects, and if not, turning to the step S502;
and S502, controlling the fan 1 to continuously work according to the expected running gear, and then returning to the step S4 until the range hood is closed.
Specifically, when it is determined that the current distance is greater than the minimum set distance, which indicates that the user does not go within the minimum set distance range, the fan 1 is controlled to continue to operate according to the expected operating range determined in step S512, and then the process returns to step S4 until the range hood is turned off. If the step S512 determines that the expected operating wind level is the low wind speed, in step S502, the fan 1 is controlled to continue to operate or operate at the low wind speed; similarly, if it is determined in step S512 that the expected operating range is the middle wind speed or the high wind speed, in step S502, the fan 1 is controlled to continue to operate or operate at the middle wind speed or the high wind speed.
Therefore, when the current distance is smaller than or equal to the minimum set distance, the range hood is controlled to execute an intelligent constant-suction strategy, so that the range hood gives consideration to the smoking effect, the phenomenon that the smoke is ignored due to the fact that the user moves to the minimum set distance range and only gives consideration to the noise reduction effect is avoided, and the situation that the smoke escapes due to the fact that the fan 1 of the range hood runs at a low wind speed is prevented.
In this embodiment, the steps of executing the smart permanent magnet strategy specifically include: and acquiring and judging whether oil smoke escapes, if not, controlling the fan to continuously work according to the expected operation gear and returning to the step S4, if so, controlling the fan to work for a period of time according to a wind speed gear which is one level higher than the expected operation gear, then controlling the wind speed gear of the fan to recover to the expected operation gear and returning to the step S4.
Specifically, whether oil smoke escapes is obtained and judged through the detection module 5, wherein the detection module 5 can be a visual sensor or a camera, and when the visual sensor or the camera detects a range threshold value to go out of the existing oil smoke, the control module 4 can judge that oil smoke escapes. When the vision sensor or the camera detects that no oil smoke exists outside the range threshold, the control module 4 can judge that no oil smoke escapes, and then the fan 1 is controlled to continue to work according to the expected operation gear, and then the step S4 is returned until the range hood is closed.
Certainly, the detection module 5 may also be a flue wind pressure sensor, and when the flue wind pressure sensor monitors that the flue resistance is greater than the wind resistance threshold, it is determined that the smoke exhaust environment is not smooth, and at this time, the smoke escape risk is large, and it may be indicated that smoke escapes. When the flue wind pressure sensor monitors that the flue resistance is not greater than the wind resistance threshold, the smoke exhaust environment is judged to be smooth, at the moment, the smoke escape risk is small, and no smoke escapes, the fan 1 is controlled to continue to work according to the expected running wind gear, and then the step S4 is returned until the range hood is closed.
In this embodiment, when the current distance is less than or equal to the minimum set distance, the fan 1 operates at the low-gear wind speed, the noise of the range hood is minimum, if no smoke escapes, the fan 1 of the range hood is controlled to continue operating or working at the low-gear wind speed, and then the step S4 is returned until the range hood is closed. Therefore, the smoke machine is ensured to have the lowest noise when in use, and the use comfort of a user is ensured.
Specifically, when the current distance is less than or equal to the minimum set distance, the expected operating gear is the low gear wind speed. When the oil smoke is judged to escape, the fan 1 of the range hood needs to be controlled to work for a period of time according to the wind speed gear with the lower wind speed higher by one level, namely the fan 1 works for a period of time according to the middle wind speed, so as to ensure the oil absorption effect of the range hood as much as possible. When the visual sensor or the camera detects that no oil smoke exists outside the range threshold value, or when the flue wind pressure sensor detects that the flue resistance is smaller than or equal to the wind resistance threshold value, the wind speed gear of the fan 1 is restored to the low-gear wind speed, and then the step S4 is returned until the range hood is closed.
Therefore, when the current distance is smaller than or equal to the minimum set distance, the noise generated when the smoke machine absorbs oil can be reduced to the greatest extent by firstly increasing the first-level wind speed gear to work for a period of time and then restoring to the expected running wind gear when oil smoke escapes, and the noise generated when the smoke machine is used can be reduced. When no oil smoke escapes, the fan 1 of the range hood is controlled to continue to operate according to the low-gear air speed, so that the lowest noise of the range hood during use is ensured.
The second adjustment manner is different from the first adjustment manner in that steps S513 and S514 between step S512 and step S501 are further included, that is, whether fine adjustment of the expected operation wind level of the fan 1 is required or not is determined according to the current angle and the preset angle. Referring to fig. 5, the current position information further includes a current angle, and the preset position information further includes a preset angle. The step of adjusting the operating windshield of the fan 1 according to the current position information and the preset position information further includes:
s513, comparing the current angle with a preset angle after determining the expected operation wind gear of the fan 1 based on the comparison result;
specifically, referring to fig. 3, the preset angle is an angle θ formed by the oa line and the ob line. The preset angle includes a minimum angle (e.g., -45 °) and a maximum angle (e.g., 45 °), and the control module 4 determines whether the current angle exceeds the range of [ minimum angle, maximum angle ].
And S514, determining whether to control the fan 1 to work according to the expected running gear based on the comparison result.
Specifically, if the current angle e [ minimum angle, maximum angle ] indicates that the user is within the preset angle, the fan 1 is controlled to operate at the desired operating gear. If it is determined in step S512 that the expected operating wind speed is the low wind speed, in step S514, the fan 1 is controlled to operate at the low wind speed; if it is determined in step S512 that the expected operating range is the middle range wind speed or the high range wind speed, the wind turbine 1 is controlled to operate at the middle range wind speed or the high range wind speed in step S514. From this, in the user is in presetting the angle, control fan 1 is according to the work of anticipated operation windshield, and the assurance noise is low, prevents that the cigarette machine noise is too big and influence user experience.
If the current angle is
[ minimum Angle, maximum Angle]And if the user is out of the preset angle, controlling the fan 1 to work at a wind speed gear which is one level higher than the expected running wind gear. Because the user is outside predetermineeing the angle, the user is just not to the cigarette machine this moment, and the cigarette machine noise is little to the user influence. In order to take the smoking effect into consideration, if it is determined in step S512 that the expected operating wind level is the low wind speed, in step S514, the fan 1 is controlled to operate at the middle wind speed; similarly, if it is determined in step S512 that the expected operating wind level is the middle wind speed, in step S514, the fan 1 is controlled to operate at the high wind speed; if it is determined in step S512 that the expected operating wind speed is the high-grade wind speed, in step S514, the fan 1 is controlled to continue to operate at the high-grade wind speed because the wind speed cannot be increased continuously. Therefore, when the user is outside the preset angle, the fan 1 is controlled to work according to the wind speed gear which is one level higher than the expected running wind gear, and the cigarette machine is guaranteed to have a good smoking effect as far as possible under the condition that the noise of the cigarette machine is low.
The third adjustment, which differs from the first adjustment, is that the desired operational profile of the wind turbine 1 is determined differently. In a third adjustment mode, an expected operation wind level of the fan 1 is determined according to the current angle and the preset angle. Referring to fig. 6, the front position information includes a current angle, and the preset position information includes a preset angle. The step of adjusting the operating wind shield of the fan 1 according to the current position information and the preset position information includes: s521, comparing the current angle with a preset angle; s522, an expected operating gear of the wind turbine 1 is determined based on the comparison result.
The fourth adjustment manner is different from the third adjustment manner in that steps S523 and S524 are further included between step S522 and step S501, that is, whether fine adjustment of the expected operating damper of the fan 1 is required or not is determined according to the current distance and the set distance. Referring to fig. 7, the current position information further includes a current distance, and the preset position information further includes a set distance; the step of adjusting the operating windshield of the fan 1 according to the current position information and the preset position information further includes: s523, comparing the current distance with the set distance after determining the expected operating wind gear of the fan 1 based on the comparison result; and S524, determining whether to control the fan 1 to work according to the expected running gear based on the analysis result.
What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept thereof, and these changes and modifications can be made without departing from the spirit and scope of the invention.
