In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Example 1
The embodiment provides a range hood control method, which is applied to a range hood used by a user, and as shown in fig. 1, the method includes the following steps:
and S11, acquiring a first signal for representing the oil smoke and a second signal for representing the noise of the range hood.
For example, the first signal for characterizing soot may be a soot concentration value and the second signal for characterizing extractor hood noise may be a noise intensity value. A lampblack detector and a noise detector are installed in the range hood, and the lampblack detector is used for detecting lampblack generated by cooking of a user to obtain a lampblack concentration value; and detecting the noise generated in the operation process of the range hood by using a noise detector to obtain a noise intensity value.
S12, when the first signal exceeds the first threshold and the second signal exceeds the second threshold, respectively calculating a first relative quantity of the first signal exceeding the first threshold and a second relative quantity of the second signal exceeding the second threshold.
Illustratively, the first threshold is a soot concentration set point; the second threshold value is a noise intensity set value; the first relative quantity and the second relative quantity are of the same data type. The first threshold and the second threshold are not limited in the present application, and can be determined by those skilled in the art according to actual needs. The relative quantity can be percentage, when the oil smoke detector detects that the oil smoke concentration value exceeds the oil smoke concentration set value and the noise detector detects that the noise intensity value exceeds the noise intensity set value, a first percentage of the oil smoke concentration value exceeding the oil smoke concentration set value and a second percentage of the noise intensity value exceeding the noise intensity set value are respectively calculated. The relative quantity can also be a ratio, when the oil smoke detector detects that the oil smoke concentration value exceeds the oil smoke concentration set value and the noise detector detects that the noise intensity value exceeds the noise intensity set value, the ratio between the oil smoke concentration value and the oil smoke concentration set value and the ratio between the noise intensity value and the noise intensity set value are respectively calculated. The relative amounts are not limited in the present application and can be determined by those skilled in the art according to actual needs.
And S13, controlling the operation parameters of the range hood according to the first relative quantity of the first signal exceeding the first threshold and the second relative quantity of the second signal exceeding the second threshold.
For example, the operating parameter of the range hood may be a motor speed, an intake air amount, noise, and the like of the range hood. Taking percentage as relative quantity as an example, the rotating speed of the motor of the range hood is controlled according to the first percentage that the oil smoke concentration value exceeds the oil smoke concentration set value and the second percentage that the noise intensity value exceeds the noise intensity set value, and then the air intake and the noise of the range hood are controlled.
According to the range hood control method, the range hood control device, the range hood and the readable storage medium provided by the embodiment, the first signal for representing oil smoke and the second signal for representing noise of the range hood are obtained, when the first signal exceeds the first threshold and the second signal exceeds the second threshold, the first relative quantity of the first signal exceeding the first threshold and the second relative quantity of the second signal exceeding the second threshold are respectively calculated, and the operating parameters of the range hood are controlled according to the first relative quantity of the first signal exceeding the first threshold and the second relative quantity of the second signal exceeding the second threshold. Because the first signal of oil smoke and the second signal of range hood noise are different in characterization dimension, the first relative quantity that the first signal of characterization oil smoke exceeded first threshold value and the second relative quantity that the second signal of characterization range hood noise exceeded the second threshold value are combined to control the operating parameter of range hood and can unify the dimension of both, the size of noise and the concentration of oil smoke can be balanced the control noise that consequently can be accurate, overcome the defect that range hood among the prior art can't realize noise and smoking effect and compromise simultaneously, user experience has been improved.
As an alternative embodiment of the present application, as shown in fig. 2, the step S13 includes:
s131, comparing the first relative quantity with the second relative quantity.
Illustratively, according to the relationship between the first relative amount and the second relative amount, the corresponding step S132 or step S133 or step S134 is performed. For example, if the calculated first relative quantity and the second relative quantity are P1 and P2, respectively, the magnitude relationship between the first relative quantity P1 and the second relative quantity P2 is determined, and step S132, step S133, or step S134 corresponding to the magnitude relationship between the first relative quantity P1 and the second relative quantity P2 is executed according to the magnitude relationship between the first relative quantity P1 and the second relative quantity P2.
S132, when the first relative quantity is larger than the second relative quantity, the rotating speed of the motor of the range hood is increased.
Illustratively, when the first relative quantity P1 is greater than the second relative quantity P2, the oil smoke concentration value representing the current cooking is greater than the noise intensity value generated by the operation of the range hood, and in order to ensure that the current cooking oil smoke concentration value and the noise intensity value generated by the operation of the range hood are in a balanced state, the rotating speed of the motor of the range hood can be appropriately increased, and the air intake of the fan is increased to reduce the oil smoke concentration value, so as to ensure that the oil smoke concentration value and the noise intensity value are balanced.
S133, when the first relative quantity is equal to the second relative quantity, the rotating speed of the motor of the range hood is maintained.
Illustratively, when the first relative quantity P1 is equal to the second relative quantity P2, the value representing the concentration of the cooking fume generated by the current cooking and the value representing the noise intensity of the operation of the range hood are in a balanced state, and at this time, the current motor speed of the range hood is maintained without adjusting the motor speed of the range hood.
S134, when the first index value is smaller than the second index value, the rotating speed of the motor of the range hood is reduced.
Illustratively, when the first relative quantity P1 is smaller than the second relative quantity P2, the noise intensity value representing the current operation of the range hood is larger than the oil smoke concentration value generated by the current cooking, and the noise intensity value generated by the operation of the range hood is larger.
As an optional embodiment of the present application, the method further comprises: and when the first signal exceeds the first threshold value but the second signal does not exceed the second threshold value, the rotating speed of the motor of the range hood is increased.
Illustratively, if the preset first threshold is Y1, the preset second threshold is X1, the soot concentration value detected by the soot detector is Y, and the noise intensity value detected by the noise detector is X, it is determined whether the soot concentration value detected by the soot detector exceeds the preset first threshold Y1, and whether the noise intensity value detected by the noise detector exceeds the preset second threshold X1. When the oil smoke concentration value Y detected by the oil smoke detector exceeds a preset first threshold value Y1 and the noise intensity value X detected by the noise detector does not exceed a preset second threshold value X1, it indicates that the oil smoke concentration value generated by current cooking is large, the rotating speed of a motor of the range hood needs to be increased, and the air intake of a fan needs to be increased to reduce the oil smoke concentration value.
As an optional embodiment of the present application, the method further comprises: and when the first signal does not exceed the first threshold value but the second signal exceeds the second threshold value, reducing the rotating speed of the motor of the range hood.
Illustratively, if the preset first threshold is Y1, the preset second threshold is X1, the soot concentration value detected by the soot detector is Y, and the noise intensity value detected by the noise detector is X, it is determined whether the soot concentration value detected by the soot detector exceeds the preset first threshold Y1, and whether the noise intensity value detected by the noise detector exceeds the preset second threshold X1. When the oil smoke concentration value Y detected by the oil smoke detector does not exceed the preset first threshold value Y1 and the noise intensity value X detected by the noise detector exceeds the preset second threshold value X1, it represents that the current range hood has a large operating noise, and the rotating speed of the motor of the range hood needs to be reduced, so that the noise generated by the operation of the range hood is reduced, and the noise intensity value of the range hood is reduced.
As an alternative embodiment of the present application, as shown in fig. 3, before step S11, the method further includes:
and S100, determining the current operation mode of the range hood.
For example, the operation mode of the range hood may be determined according to an operation instruction input by a user. The operating modes of the range hood may include a noise priority mode, a smoking priority mode, and a balance mode. Wherein, the noise priority mode is: when the noise intensity value detected by the noise detector exceeds a preset second threshold value, the rotating speed of the motor of the range hood is reduced, and then the reduction of the noise intensity value is realized without considering that the oil smoke detector detects an oil smoke concentration value. The smoking priority mode is as follows: when the oil smoke concentration value detected by the oil smoke detector exceeds a preset first threshold value, the rotating speed of a motor of the range hood is increased, the air intake of the range hood is increased, the oil smoke concentration value is reduced, and the noise intensity value detected by the noise detector is not considered. The balance mode is as follows: and determining to maintain or reduce or improve the motor rotating speed of the range hood according to whether the oil smoke concentration value detected by the oil smoke detector exceeds a preset first threshold value and whether the noise intensity value detected by the noise detector exceeds a preset second threshold value.
S101, when the current operation mode of the range hood is a balance mode, a step of acquiring a first signal for representing oil smoke and a second signal for representing noise of the range hood is executed.
For example, if the operation command input by the user is received and corresponds to the balance mode of the range hood, the range hood executes the range hood control method described in the above steps S11 to S15 according to the current balance mode. For details, refer to the description corresponding to the above embodiments, and are not repeated herein.
As an optional implementation manner of the present application, as shown in fig. 3, the range hood control method further includes:
s102, when the current operation mode of the range hood is a smoking priority mode, a first signal is obtained.
For example, if the received operation instruction input by the user corresponds to the smoke priority mode of the range hood, the range hood only needs to acquire the first signal for representing the oil smoke according to the current smoke priority mode, and does not need to acquire the second signal for representing the noise of the range hood. For details of obtaining the second signal for representing the oil smoke, reference is made to the corresponding related description of the above embodiments, and details are not repeated here.
S103, judging whether the second signal is larger than the first threshold value.
For example, if the preset first threshold is Y1 and the smoke intensity value detected by the smoke detector is Y, the preset first threshold Y1 is compared with the smoke intensity value Y, and it is determined whether the smoke intensity value Y detected by the smoke detector is greater than the preset first threshold Y1.
And S104, if the second signal is greater than the first threshold value, increasing the rotating speed of the motor of the range hood.
Exemplarily, when the oil smoke intensity value Y detected by the oil smoke detector exceeds a preset first threshold value Y1, it represents that the oil smoke concentration value of the current range hood is large, and it is necessary to increase the motor rotation speed of the range hood, increase the intake air volume of the range hood, and further reduce the oil smoke concentration value. And the oil smoke detector detects the concentration value of the oil smoke generated by cooking in real time until the concentration value of the oil smoke meets the preset first threshold value requirement. And if the oil smoke intensity value Y detected by the oil smoke detector does not exceed a preset first threshold value Y1, maintaining the current motor rotating speed of the range hood.
As an optional implementation manner of the present application, as shown in fig. 3, the range hood control method further includes:
and S105, acquiring a second signal when the current operation mode of the range hood is the noise priority mode.
Illustratively, if the received operation instruction input by the user corresponds to the noise priority mode of the range hood, the range hood only needs to acquire the second signal for representing the noise of the range hood according to the current noise priority mode, and does not need to acquire the first signal for representing the oil smoke. For details of obtaining the first signal for representing the noise of the range hood, reference is made to the corresponding related description of the above embodiments, and details are not repeated here.
And S106, judging whether the second signal is larger than a second threshold value.
For example, if the preset second threshold is X1 and the noise intensity value detected by the noise detector is X, the noise intensity value detected by the noise detector is compared with the preset second threshold X1 to determine whether the noise intensity value detected by the noise detector is greater than the preset second threshold X1.
And S107, if the second signal is greater than the second threshold value, reducing the rotating speed of the motor of the range hood.
Exemplarily, when the noise intensity value X detected by the noise detector exceeds a preset second threshold value X1, the operating noise representing the current range hood is relatively large, the motor rotation speed of the range hood needs to be reduced, and then the noise generated by the operation of the range hood is reduced, and the noise intensity value of the range hood is reduced. And if the noise intensity value X detected by the noise detector does not exceed a preset second threshold value X1, maintaining the current motor rotating speed of the range hood.
Through setting the control mode of the range hood, a user can select the control mode required to operate according to the requirement, so that the noise and the smoking effect of the range hood reach the expected state, the requirements of the user on different control modes are met, and the user experience is improved.
