[0024] Figure 1 This is a schematic diagram of the first process of the range hood control method provided by the present invention. The method of the present invention is applicable to intelligent electrical appliance control scenarios. The method can be executed by the range hood control device provided by the present invention and applied to the client. The device can be implemented in software and / or hardware. In a specific embodiment, the device can be integrated in an electronic device, such as a controller of the client. The following embodiments will be described by taking the device integrated in the controller of the client as an example. Figure 1 , the method may specifically include the following steps:

[0025] Step 101: Receive a pipeline back pressure detection start instruction sent by the current user.

[0026] Among them, the start instruction is used to instruct the range hood to start the back pressure detection program. The back pressure detection program is used to detect the back pressure of the pipes in the user's home. In this solution, the user's range hood is connected to the user terminal for communication, and the user terminal can be the user's mobile phone, tablet computer, etc. In an optional embodiment, when the user needs to use the range hood and needs to use the back pressure detection program, a start instruction can be sent to the range hood through the terminal. Alternatively, the user can instruct the range hood to start the back pressure detection program through the touch button on the display screen of the range hood.

[0027] Step 102 , in response to the start instruction, the target air volume of each gear corresponding to the pipeline back pressure of the current user is determined according to the preset current and the predetermined back pressure database of the current user.

[0028] Among them, the preset current is the current pre-set by the range hood according to the field big data, etc. The back pressure database of the current user is a database pre-stored in the range hood, determined according to the kitchen environment of the current user, etc. The back pressure database stores the pipeline back pressures corresponding to each motor current and each motor speed. In an optional embodiment, before receiving the start instruction of the pipeline back pressure detection sent by the current user, the motor speed test is performed based on the pre-set motor currents to obtain the motor speeds corresponding to each motor current; based on the pre-set motor torque, the balance equation of the turbine and the pipeline back pressure, each motor current and each motor speed, the pipeline back pressures corresponding to each motor current and its corresponding motor speed are determined; the back pressure database of the current user is determined according to each motor current, each motor speed and each pipeline back pressure.

[0029] In an optional implementation, the motor of the range hood is controlled to rotate according to a preset current, and the start time of the motor rotation is recorded; from the start time, the motor speed at each preset time interval is obtained according to the preset time interval within the first preset time length; the target speed of the motor is determined based on the speed of the motor at all preset time intervals. The duct back pressure corresponding to the target speed of the motor is determined in the back pressure database corresponding to the current user; the target air volume of each gear corresponding to the duct back pressure is determined according to the predetermined back pressure gear air volume relationship table.

[0030] Step 103: exhaust smoke based on each gear position and the target air volume of each gear position.

[0031] The target air volume of each gear is the air volume that the range hood should provide at each gear, which is finally determined by the range hood. In the embodiment of this scheme, smoke exhaust is optionally performed based on each gear and the target air volume of each gear, including: obtaining oil fume data at the current moment, and determining the target gear at the current moment based on the oil fume data; and exhausting oil fume based on the target air volume corresponding to the target gear.

[0032] Among them, the oil fume data includes the oil fume volume and oil fume concentration. The target gear is the gear corresponding to the oil fume data at the current moment. In this solution, the range hood includes an oil fume volume detector and an oil fume concentration detector. The oil fume concentration detector can measure the concentration of oil fume particles in the air. The oil fume concentration detector usually adopts laser scattering or optical principles to determine the oil fume concentration by measuring the degree of scattering of light by oil fume particles. The oil fume volume detector can measure the total amount of oil fume near the range hood. The oil fume volume detector usually adopts the principle of a flow meter to determine the amount of oil fume by measuring the volume of gas flowing through the equipment.

[0033] In an optional implementation, after the range hood determines the oil fume concentration and oil fume volume, the current gear corresponding to the oil fume concentration and oil fume volume at the current moment can be searched in a pre-stored gear table. After the current gear at the current moment is determined, the target air volume corresponding to the current gear is determined according to each gear and the target air volume of each gear, and the smoke exhaust operation is performed according to the target air volume of the current gear.

[0034] The technical solution of this embodiment can receive a start instruction for the duct back pressure detection sent by the current user. In response to the start instruction, the target air volume for each gear corresponding to the duct back pressure of the current user is determined according to the preset current and the predetermined back pressure database of the current user. Smoke exhaust is performed based on each gear and the target air volume of each gear. The technical solution of this embodiment can determine the duct back pressure in the current user's home according to the current of the motor, and adjust the air volume corresponding to each gear under the duct back pressure, so as to provide the user with an air volume suitable for the user's kitchen environment to remove oil smoke, thereby improving the working efficiency of the range hood and improving the user experience.

[0035] Figure 2 This is a second flow chart of the range hood control method provided by the present invention. The specific method can be as follows: Figure 2 As shown, the method may include the following steps:

[0036] Step 201: Receive a pipeline back pressure detection start instruction sent by the current user.

[0037] Step 202: In response to the start instruction, determine the target speed of the motor based on the preset current.

[0038] The preset current is the current pre-set by the range hood according to the domain big data, etc. In this solution, determining the target speed of the motor based on the preset current includes: controlling the motor of the range hood to rotate according to the preset current, and recording the start time of the motor starting to rotate, and from the start time, obtaining the speed of the motor at each preset time interval according to the preset time interval within the first preset time length; determining the target speed of the motor based on the speed of the motor at all preset time intervals.

[0039] Among them, the motor of the range hood can be a variable frequency motor. The first preset duration is the duration pre-set by the range hood according to field big data and the like. Specifically, when the pipeline back pressure detection program is turned on, the range hood can give the variable frequency motor a fixed current, that is, a preset current. The variable frequency motor will rotate under the action of the preset current, but its rotation speed is unstable at the beginning. In order to obtain a stable rotation speed of the variable frequency motor, when the variable frequency motor starts to rotate, the start time of the variable frequency motor is recorded. Within the preset duration, the rotation speed of the motor in each preset time interval is obtained according to the preset time interval. After obtaining the rotation speed of the variable frequency motor in each preset time interval, the average value of the rotation speed of the variable frequency motor in all preset time intervals is calculated, and the average value is determined as the target speed of the motor.

[0040] Exemplarily, the first preset duration is 25 seconds, and the preset time interval is 5 seconds. The start time is 13:00:00, and the preset current is A. At the start time, the motor starts to rotate, and the speed is a. The speed of the motor at 13:00:05 is b, the speed at 13:00:10 is c, the speed at 13:00:15 is d, the speed at 13:00:20 is e, and the speed at 13:00:25 is f. Then the target speed of the motor can be determined as: (a+b+c+d+e+f) / 5.

[0041] In the above steps, by giving the range hood a fixed current, the speed of the motor of the range hood can be accurately obtained, which lays the foundation for subsequently providing an air volume suitable for the user's kitchen environment.

[0042] Step 203: Determine the pipeline back pressure corresponding to the target speed of the motor in the back pressure database corresponding to the current user.

[0043] The back pressure database stores the corresponding relationship between each motor current, each motor speed and each pipeline back pressure corresponding to the kitchen environment of the current user. In this solution, determining the back pressure database corresponding to the current user includes the following steps A1-A2:

[0044] Step A1: Perform a motor speed test based on each pre-set motor current to obtain each motor speed corresponding to each motor current.

[0045] Specifically, the variable frequency motor is a driving actuator and also a sensor device. The speed and torque of the variable frequency motor are usually one-to-one corresponding. Under the same torque, the actual speed of the motor is affected by the back pressure environment. When the back pressure increases, the motor needs to generate a larger torque to overcome the resistance, which causes the actual speed to decrease. On the contrary, when the back pressure decreases, the torque required by the motor decreases, and the actual speed may increase. Therefore, in order to obtain the corresponding relationship between each motor current, each motor speed and each pipeline back pressure, a plurality of different motor currents can be given to the variable frequency motor, so that the variable frequency motor rotates under the drive of each motor current and generates different speeds. Further, the motor speed of the variable frequency motor under each motor current is recorded.

[0046] Step A2: Based on the preset motor torque, the balance equation of the turbine and pipeline back pressure, each motor current and each motor speed, determine each pipeline back pressure corresponding to each motor current and its corresponding motor speed; determine the back pressure database of the current user according to each motor current, each motor speed and each pipeline back pressure.

[0047] Specifically, the motor speed and torque are in one-to-one correspondence, so the motor torque can be determined according to the motor speed. In this solution, the preset balance equation of the motor torque, turbine and pipeline back pressure is: T 转矩 =T 涡轮 +T 管道 Among them, T 转矩 Represents the torque of the motor, T 涡轮 Indicates the resistance generated by the turbine rotation. 管道 Indicates pipeline back pressure. That is, when the torque provided by the motor reaches a balance with the resistance generated by the turbine rotation plus the pipeline back pressure, the speed stabilizes. Furthermore, the motor currents and their corresponding motor speeds and pipeline back pressures obtained in the experiment are stored in correspondence to obtain the back pressure database of the current user.

[0048] In an optional embodiment, after the range hood determines the target speed of the motor based on the preset current, a motor speed that is the same as or close to the target speed can be found in the back pressure database corresponding to the current user, and the pipe back pressure corresponding to the motor speed in the back pressure database can be determined as the pipe back pressure corresponding to the target speed of the motor.

[0049] Through the above steps, the back pressure database corresponding to the current user's kitchen environment can be determined, so that the range hood can accurately determine the duct back pressure in the current user's home based on the motor current and speed, laying the foundation for subsequently providing air volume suitable for the user's kitchen environment.

[0050] Step 204: Determine the target air volume for each gear corresponding to the pipeline back pressure according to a predetermined back pressure gear air volume relationship table.

[0051] The back pressure level air volume relationship indicates the air volume corresponding to each level of the range hood under each predetermined back pressure of the range hood. After determining the duct back pressure corresponding to the target speed, the duct back pressure equal to or close to the duct back pressure of the target speed can be found in the back pressure level air volume relationship table, and the air volume corresponding to each level of the range hood under the duct back pressure can be determined as the target air volume of each level.

[0052] For example, the range hood has three gears, namely gear A, gear B and gear C. The back pressure gear air volume relationship table stores the air volume corresponding to each gear under the five pipeline back pressures, as shown in Table 1 below:

[0053]

[0054]

[0055] Table 1

[0056] Assuming that the range hood determines that the duct back pressure corresponding to the target speed of the motor is closest to the duct back pressure 5 in Table 1, it can be determined that under the duct back pressure corresponding to the target speed of the motor, the target air volume corresponding to gear A is 5a, the target air volume corresponding to gear B is 5b, and the target air volume corresponding to gear C is 5c.

[0057] Step 205: Send each gear position and the target air volume corresponding to each gear position to the user.

[0058] Specifically, after determining each gear and the target air volume corresponding to each gear, in order to fully understand the user's preferences and provide services that meet the user's needs, the range hood can send each gear and the target air volume corresponding to each gear to the user through the touch display screen on the range hood or through the user terminal, so that the user can view or modify the target air volume corresponding to each gear.

[0059] Step 206: If a modification instruction sent by the user is received within the second preset time period, determine the modified gear and the modified air volume corresponding to the modified gear based on the modification instruction.

[0060] The modification instruction is an instruction sent by the user to the range hood to modify the target air volume corresponding to the gear position of the range hood. The modified gear position is the gear position after the user modifies its corresponding target air volume, and the modified air volume is the target air volume after the user modifies it.

[0061] Specifically, after the range hood sends each gear and the target air volume corresponding to each gear to the user, the user can modify the target air volume corresponding to each gear according to his or her own needs through the touch screen of the range hood or through the user terminal, that is, send a modification instruction to the range hood. After receiving the modification instruction, the range hood determines the modified gear and the modified air volume corresponding to the modified gear according to the modification instruction.

[0062] Step 207: If the modified air volume is within the predetermined air volume modification range, the target air volume corresponding to the modified gear position is updated based on the modified air volume.

[0063] The air volume modification range is a range that is pre-determined by the range hood based on domain big data, etc., and is used to determine whether the user's modification of the target air volume is appropriate. Specifically, the user can modify each gear and the target air volume corresponding to each gear according to their own needs. However, in order to prevent the user from accidentally touching or affecting the normal operation of the range hood due to the user's modification range being too large, the range hood needs to determine whether the target air volume corresponding to at least one gear modified by the user is within an appropriate range. If the modified air volume is within the pre-determined air volume modification range, the target gear and target air volume are updated based on the modified gear and the modified air volume.

[0064] Exemplarily, the range hood determines that under the duct back pressure corresponding to the target speed of the motor, the target air volume corresponding to the A gear is 5a, the target air volume corresponding to the B gear is 5b, and the target air volume corresponding to the C gear is 5c. The air volume modification range is [-f, f]. The user modifies the target air volume corresponding to the B gear to 5e, and -f≤5e-5b≤f, then it can be determined that the modified air volume is within the predetermined air volume modification range. Further, the range hood can determine that under the duct back pressure corresponding to the target speed of the motor, the target air volume corresponding to the A gear is 5a, the target air volume corresponding to the B gear is 5e, and the target air volume corresponding to the C gear is 5c.

[0065] Step 208: If the modified air volume is not within the air volume modification range, generate a prompt message based on the modified gear position and the modified air volume; and send the prompt message to the user to prompt the user that the modification exceeds the range.

[0066] If the modified air volume is not within the predetermined air volume modification range, it means that the target air volume of at least one gear modified by the user is not within the appropriate range, which may affect the normal operation of the range hood. At this time, the range hood can generate a prompt message according to the gear modified by the user and the corresponding modified air volume, and send a prompt message to the user through the range hood touch screen and voice announcer, or the user terminal, to prompt the user that the modification is out of range.

[0067] Exemplarily, the range hood determines that under the duct back pressure corresponding to the target speed of the motor, the target air volume corresponding to the A gear is 5a, the target air volume corresponding to the B gear is 5b, and the target air volume corresponding to the C gear is 5c. The air volume modification range is [-f, f]. If the user modifies the target air volume corresponding to the B gear to 5n, and 5n-5b≥f, it can be determined that the modified air volume is not within the predetermined air volume modification range. Further, the range hood can play a voice prompt "Modification exceeds the range, please modify again" to the user, and at the same time display a subtitle "Modification exceeds the range, please modify again" to the user on the touch screen of the range hood to prompt the user to modify beyond the range.

[0068] Step 209: exhaust smoke based on each gear position and the target air volume of each gear position.

[0069] In this embodiment, a start instruction for pipeline back pressure detection sent by the current user is received. The target speed of the motor is determined based on the preset current. The pipeline back pressure corresponding to the target speed of the motor is determined in the back pressure database corresponding to the current user. The target air volume of each gear corresponding to the pipeline back pressure is determined according to a predetermined back pressure gear air volume relationship table. The target gear and the target air volume corresponding to the target gear are sent to the user. If a modification instruction sent by the user is received within a second preset time length, the modified gear and the modified air volume corresponding to the modified gear are determined based on the modification instruction. If the modified air volume is within a predetermined air volume modification range, the target air volume corresponding to the modified gear is updated based on the modified air volume. If the modified gear is not within the gear modification range, or the modified air volume is not within the air volume modification range, a prompt message is generated based on the modified gear or the modified air volume; the prompt message is sent to the user to prompt the user that the modification is out of range. Smoke exhaust is performed based on each gear and the target air volume of each gear. The technical solution of this embodiment determines the current duct back pressure in the user's home based on the current of the motor, and adjusts the air volume corresponding to each gear under the duct back pressure, providing the user with an air volume suitable for the user's kitchen environment to remove oil smoke and improve the working efficiency of the range hood. In addition, the user can modify the target air volume corresponding to each gear through the terminal, so that the range hood can provide users with services that better meet their needs, thereby improving the user experience.
