Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a flowchart of a method for controlling a range hood according to an embodiment of the present invention, where the embodiment is applicable to a situation where a temperature of a pot, a pressure in an exhaust duct, and smoke of oil smoke are detected in real time, and a rotation speed of the range hood is controlled according to a detection result, and the method may be executed by a range hood control device, and the device may be implemented in a hardware and/or software manner, and may be generally integrated in a range hood, as shown in fig. 1, specifically including the following steps:
s110: monitoring temperature information of the cookware, and forming a temperature curve segment based on the temperature information.
In this embodiment, the temperature information of the pot can be monitored by the temperature sensing module, and the temperature sensing module can be an infrared temperature sensing module or a temperature sensor. Wherein, when the user opened smoke ventilator, infrared temperature sensing module was opened promptly to carry out real-time detection to the temperature of pan on the basis of contactless pan. The temperature sensor may be a contact temperature sensor, or may also be a non-contact temperature sensor. .
In the embodiment of the present invention, the temperature information may be temperature information at each time point within a certain period of time, where the temperature information at each time point forms a temperature curve segment.
S120: and judging the type of the temperature curve to which the temperature curve segment belongs.
Wherein, the type of the temperature curve refers to the cooking type of the user corresponding to the temperature curve segment. The temperature curve segment can be matched with the temperature curves of various types, the temperature curve matched with the temperature curve segment is determined and used as the temperature curve of the temperature curve segment, and therefore the type of the temperature curve is determined. For example, if the temperature curve segment matches the temperature curve of the water boiling type, the temperature curve segment belongs to a portion of the temperature curve of the water boiling type, and the type of the temperature curve to which the temperature curve segment belongs is the water boiling type.
S130: and judging whether the monitored pressure in the exhaust pipeline is smaller than a set pressure value.
If yes, go to S140; if not, go to S150.
Wherein, the accessible is installed atmospheric pressure check out test set in lampblack absorber air outlet position and is monitored the pressure in the exhaust pipe. The problem that the rotating speed of the current range hood cannot meet the requirements of users due to the fact that the temperature of a cooker is low and the pressure in an exhaust pipeline is high is solved. Specifically, the pressure in the exhaust duct is monitored by the air pressure detection module arranged at the air outlet of the range hood in the embodiment. Wherein, the set pressure value can be set as required.
S140: and controlling the rotating speed of the range hood based on the type of the temperature curve.
In the embodiment of the invention, for example, the rotating speed of the range hood can be controlled according to the temperature and the change amount in the temperature curve segment. For example, taking the type of the temperature curve as a water boiling type as an example, according to the wiring form of the curve segment, the rotating speed of the range hood can be adjusted to be in a smaller state before water is not boiled, namely when the curve is in a linear rising state and the slope of the curve is larger; when the curve is in a linear rising state and the slope becomes small, the water is about to be boiled at the moment, and the rotating speed of the range hood is adjusted to be in a larger state. The present embodiment does not limit this.
If the pressure in the exhaust pipeline is monitored to be smaller than the set pressure value, the fact that smoke in a kitchen is small at the moment is proved, the range hood does not need to work in a high-rotation-speed working state, the requirement can be met only by controlling the rotation speed of the range hood according to the type of a temperature curve, and unnecessary noise trouble caused by the fact that the pressure in the exhaust pipeline is small and the rotation speed of a motor of the range hood is too high is avoided.
S150: and monitoring the smoke value of the oil smoke.
Wherein, the smog value of oil smoke is monitored to the mode that image recognition is carried out to near the image of shooing of lampblack absorber to the smog value in the surrounding environment is monitored when pressure in the exhaust duct is too big, effectively solves the too big and can not satisfy the condition of user's demand by temperature control's lampblack absorber rotational speed in the exhaust duct. Specifically, the smoke value of the oil smoke can be monitored through the image recognition module in the embodiment.
If the pressure in the exhaust pipeline is monitored to be larger than a set pressure value, the fact that the smoke in a kitchen is large at the moment is proved, and the requirement cannot be met only by controlling the rotating speed of the range hood according to the type of a temperature curve. At the moment, the smoke in the kitchen can be discharged more intuitively and effectively in time by controlling the range hood through the smoke value.
S160: and if the smoke value is smaller than the preset smoke value, controlling the rotating speed of the range hood based on the smoke value.
The preset smoke value refers to a preset numerical value for evaluating the monitored smoke value. Generally, the set value can be set according to the degree of the requirement of the user on the actual environment, for example, if the requirement of the user on the environment is higher, the preset smoke value can be set to be lower; if the requirement of the user on the environment is low, the preset smoke value can be set to be higher. The present embodiment does not limit this.
The rotating speed of the range hood can be controlled according to the preset relation between the smoke value and the rotating speed of the range hood. For example, a mapping table indicating a correspondence between the smoke value and the rotational speed of the range hood may be preset between the smoke value and the rotational speed of the range hood. For example, the smoke value of 100-200 corresponds to the low rotation speed of the range hood; the smoke value of 200-300 corresponds to the rotation speed in the range hood. And finding the rotating speed of the range hood corresponding to the smoke value in the relational mapping table according to the smoke value, and further controlling the range hood. The present embodiment does not limit this.
On the basis of the above embodiment, the method provided by the embodiment of the present invention may further include controlling the range hood to operate at the highest rotation speed if the smoke value is greater than the preset smoke value.
Specifically, when the smoke value is larger than the preset smoke value, the range hood is controlled to operate at the highest rotating speed no matter what state the rotating speed of the range hood is.
When the smoke value is larger than the preset smoke value, the smoke content in the kitchen reaches the maximum smoke value acceptable by the user, and the smoke in the kitchen must be removed as soon as possible to meet the requirements of the user. If the range hood is still controlled by the method, a control delay phenomenon may occur, so that smoke cannot be discharged in time.
According to the technical scheme of the embodiment of the invention, the temperature of the cooker, the pressure in the exhaust pipeline and the smoke of the oil smoke are detected in real time, and when the pressure in the exhaust pipeline is smaller than a set pressure value, the rotating speed of the range hood is controlled according to the type of a temperature curve; the pressure in the exhaust duct is greater than the smog value that sets for the pressure value and monitor and is less than preset smog value, based on smog value control the rotational speed of lampblack absorber, the rotational speed of accurate control lampblack absorber can avoid the less unnecessary noise puzzlement that causes of the motor rotational speed of the interior pressure of exhaust duct as far as possible and the too high time oil smoke in the kitchen can in time be discharged when pressure in the exhaust duct is too big again.

First set temperature value can be the temperature that the pan reached when water was boiled in this embodiment to this judges the state of heating up water, and then controls the rotational speed of lampblack absorber, or can also be other temperature values.
S250: and if the monitored temperature is increased to a first set temperature value, controlling the range hood to be at a second speed.
The second speed refers to a numerical value which corresponds to the first speed and is used for evaluating the rotating speed of the range hood, and the first speed is lower than the second speed in the embodiment; the second speed is between the minimum rotating speed and the maximum rotating speed of the range hood.
Specifically, when the temperature of the cookware rises but is not at the temperature of water boiling in the water boiling type, the range hood is controlled to operate at the minimum rotating speed, so that unnecessary noise influence caused by too high rotating speed of the range hood due to low temperature is avoided; when the temperature of the cooker reaches the temperature when water is boiled, the rotating speed of the range hood is controlled to operate at a higher rotating speed, so that steam in a kitchen can be effectively removed in time, and unnecessary noise influence caused by too high rotating speed of the range hood is reduced as much as possible.
The advantage of above-mentioned technical scheme lies in, controls the lampblack absorber rotational speed of the type of heating up water through the temperature curve, can in time get rid of the steam in the kitchen effectively to minimize the too big unnecessary noise influence that causes of lampblack absorber rotational speed.

If yes, go to step S340, otherwise go to step S360.
S340: if the type of the temperature curve is a soup cooking type, the temperature increase of the cooker is monitored, and the temperature is smaller than a second set temperature value, the range hood is controlled to be at a second rotating speed.
The second set temperature value refers to a preset temperature value for evaluating the temperature of the cookware and can correspond to the rotating speed of the oil smoke. The second set temperature value is greater than the first set temperature value in this embodiment to this judges the soup cooking state, and then controls the rotational speed of lampblack absorber.
And the second rotating speed is between the minimum rotating speed and the maximum rotating speed of the range hood.
S350: and if the monitored temperature is increased to a second set temperature, controlling the range hood to be at a third rotating speed.
And the third rotating speed is the highest rotating speed of the range hood.
Specifically, when the type of cooking soup is monitored, the temperature of the cooker rises quickly at the beginning but does not reach the temperature value to be reached for cooking the soup, the range hood is controlled to operate at a higher rotating speed, so that the smell of the soup remaining in the kitchen can be reduced, and the unnecessary noise influence caused by the too high rotating speed of the range hood is reduced as much as possible; when the temperature of the cooker reaches the temperature when the soup is continuously cooked, the range hood is controlled to operate at the maximum rotating speed so as to discharge the smell in the kitchen in time.

S420: and judging the type of the temperature curve to which the temperature curve segment belongs.
S430: and judging whether the monitored pressure in the exhaust pipeline is smaller than a set pressure value.
If yes, go to S440, otherwise go to S460.
S440: if the type of temperature curve is the type of cooking, in first preset time quantum, if the temperature of pan is in first temperature interval or second temperature interval, just the temperature difference between the temperature of pan and ambient temperature is greater than first difference in temperature threshold value, and the temperature change rate is greater than first change rate threshold value just the temperature change rate is less than 0, control the lampblack absorber rotational speed is the third rotational speed.

The first rotating speed is the lowest rotating speed of the range hood; the first temperature interval is a highest temperature interval, the third temperature interval is a lowest temperature interval, and the second temperature interval is between the highest temperature interval and the lowest temperature interval.
The second change rate threshold refers to a preset threshold for evaluating the temperature change rate during cooking dishes, and can be generally set according to the temperature change rate with slow temperature change during the cooking process.
Specifically, when the temperature of the pot is rapidly reduced in the cooking type, the fact that the cooking is just put into the pot at the moment is proved to be that the oil smoke in the environment is very large, and the rotating speed of the range hood is adjusted to be the highest rotating speed so as to remove the oil smoke in the environment as soon as possible; when the temperature of the cooker becomes stable, the cooker is proved to enter a stewing state, the oil smoke is not very large, the rotating speed of the range hood is adjusted to the lowest rotating speed without a range hood with high rotating speed, the oil smoke in a kitchen can be effectively discharged in time, and unnecessary noise influence caused by too large rotating speed of the range hood is reduced.
