Figure 1 As shown, the method may specifically include the following steps:

[0029] S101, determining the flue resistance generated when the fan is operated according to the user's default gear position, and determining a candidate gear position of the fan based on the flue resistance.

[0030] Among them, the default custom gear can be understood as the fan gear preset by the user in the time interval to which the current time belongs; the candidate gear can be understood as the fan gear determined according to the flue resistance.

[0031] In an optional implementation, a first operating parameter of a motor when the fan is running in a user's default gear position is obtained, and a second operating parameter of a power board is obtained; the flue resistance is determined according to the first operating parameter and the second operating parameter. According to the flue resistance, preset information is queried to obtain a candidate air volume corresponding to the flue resistance, and a candidate gear position of the fan is determined according to the candidate air volume, wherein the preset information includes candidate air volumes corresponding to each flue resistance.

[0032] Specifically, the flue resistance may be obtained by querying the flue resistance information according to the first operating parameter and the second operating parameter, and the flue resistance information includes the flue resistances corresponding to the first operating parameter and the second operating parameter respectively.

[0033] For example, the flue resistance is A, and the candidate air volume corresponding to the flue resistance A in the preset information is W1. The preset information is queried according to the flue resistance A to obtain the candidate air volume W1 corresponding to the flue resistance, and the candidate gear of the fan is determined according to the candidate air volume W1.

[0034] S102, controlling the fan to operate according to the candidate gear to generate a candidate air volume.

[0035] S103, obtaining smoke concentration, and when the smoke concentration is greater than a preset concentration, determining a target air volume based on the candidate air volumes and a preset increased air volume value.

[0036] The preset concentration may be understood as a preset critical value of the smoke concentration; and the preset increased air volume may be understood as an increased air volume of the preset candidate air volumes.

[0037] In an optional implementation, the candidate air volume and the preset increase air volume are added to obtain the adjusted air volume; based on the adjusted air volume and the maximum candidate air volume in the preset information, the target air volume is determined. The adjusted air volume can be understood as the sum of the candidate air volume and the preset increase air volume.

[0038] For example, the candidate air volume is W1, the preset increased air volume is W2, the candidate air volume and the preset increased air volume are added to obtain the adjusted air volume W3; based on the adjusted air volume W3 and the maximum candidate air volume in the preset information, the target air volume W4 is determined.

[0039] S104, determining a target gear of the fan according to the target air volume, and controlling the fan to switch from the candidate gear to the target gear.

[0040] In an optional implementation, each target air volume corresponds to a target gear position of a fan, so the target gear position of the fan corresponding to the target air volume can be determined by querying gear position information according to the target air volume. The gear position information may include the target gear positions corresponding to each target air volume.

[0041] For example, the target air volume is W4, and when the target air volume in the gear information is W4, the corresponding target gear of the fan is D. The gear information can be queried according to the target air volume W4 to determine the target gear D of the fan corresponding to the target air volume W4, and the fan can be controlled to switch from the candidate gear to the target gear D to generate the target air volume W4.

[0042] In this embodiment, the range hood automatically operates according to the user's default custom gear after being turned on, based on the user's daily usage habits. The user does not need to manually adjust the gear of the range hood to the default custom gear after the range hood is turned on, thereby improving the compatibility of the user group. After the air volume is generated according to the user's default custom gear, the flue resistance generated when the fan runs according to the user's default custom gear is determined, and a candidate gear of the fan is determined based on the flue resistance; the fan is controlled to operate according to the candidate gear to generate a candidate air volume, that is, on the basis of the air volume generated by the default custom gear, the air volume is dynamically adjusted in combination with the flue resistance to obtain the candidate air volume; then the smoke concentration is obtained, and when the smoke concentration is greater than the preset concentration, the smoke concentration is adjusted based on the candidate air volume and the preset increase Adding the air volume value to determine the target air volume is equivalent to adjusting the candidate air volume again within a certain air volume range based on the candidate air volume to obtain the target air volume, and finally determining the target gear of the fan according to the target air volume, and controlling the fan to switch from the candidate gear to the target gear to achieve automatic air volume adjustment for the air volume generated by the default gear within a certain air volume range in combination with the flue resistance and smoke concentration, and then automatically switching the gear according to the air volume, so that the range hood can exhaust smoke intelligently, improve the flexibility, intelligence and convenience of the range hood fan gear control, solve the problem that users can only manually adjust the range hood fan gear based on experience, which is not intelligent and convenient enough, and bring users a better user experience.

[0043] Figure 2 Another flow chart of the range hood gear control method provided by the embodiment of the present invention is as follows: Figure 2 As shown, the method may include the following steps:

[0044] S201, obtaining the current time.

[0045] S202: Determine the time interval to which the current time belongs.

[0046] The time interval may include multiple time intervals. For example, one day may be divided into three time intervals: (0 o'clock, 10 o'clock], (10 o'clock, 18 o'clock], and (18 o'clock, 0 o'clock].

[0047] S203, determining the default custom gear position of the corresponding user according to the time interval.

[0048] S204, obtaining a first operating parameter of the motor when the fan is running according to the user's default custom gear, and obtaining a second operating parameter of the power board.

[0049] S205, determining the flue resistance according to the first operating parameter and the second operating parameter.

[0050] S206, querying preset information according to the flue resistance to obtain candidate air volumes corresponding to the flue resistance, wherein the preset information includes candidate air volumes corresponding to each flue resistance.

[0051] S207, determining candidate gear positions of the fan according to the candidate air volumes.

[0052] In an optional implementation, each candidate air volume corresponds to a candidate gear position of the fan, so the candidate gear position of the fan corresponding to the candidate air volume can be determined by querying gear position information according to the candidate air volume. The gear position information may include the candidate gear positions corresponding to each candidate air volume.

[0053] S208, controlling the fan to operate according to the candidate gear to generate the candidate air volume.

[0054] S209, obtaining smoke density.

[0055] In an optional implementation, the smoke concentration may be obtained by detecting smoke through a smoke sensor.

[0056] S210, determining whether the smoke concentration is greater than a preset concentration. When the smoke concentration is not greater than the preset concentration, returning to S209, and when the smoke concentration is greater than the preset concentration, executing S211.

[0057] S211, accumulating the candidate air volume and the preset increased air volume to obtain the adjusted air volume.

[0058] S212: Determine the target air volume based on the adjusted air volume and the maximum candidate air volume in the preset information.

[0059] In an optional implementation, when the adjusted air volume is greater than the maximum candidate air volume, the maximum candidate air volume is determined as the target air volume; when the adjusted air volume is not greater than the maximum candidate air volume, the adjusted air volume is determined as the target air volume.

[0060] For example, the candidate air volume is A1, the preset increase air volume is m, the maximum candidate air volume in the preset information is An, the candidate air volume A1 and the preset increase air volume m are added to obtain the adjusted air volume A1+m, when the adjusted air volume A1+m is greater than the maximum candidate air volume An, the maximum candidate air volume An is determined as the target air volume; when the adjusted air volume A1+m is not greater than the maximum candidate air volume An, the adjusted air volume A1+m is determined as the target air volume.

[0061] S213, determining a target gear of the fan according to the target air volume, and controlling the fan to switch from the candidate gear to the target gear.

[0062] In this embodiment, when the first flue blockage level is a light blockage and the first current gear is a high-speed gear, the gear change mode of the fan is determined to maintain the high-speed gear for a preset period of time and then run at a medium-speed gear. In this way, the gear switching mode corresponding to each first flue blockage level and the first current gear can be determined more accurately and intelligently according to the level of the first flue blockage level and the level of the first current gear, so that the range hood can automatically and flexibly change the current gear according to the gear change mode according to each first flue blockage level and the first current gear, thereby improving the flexibility and convenience of the range hood fan gear change, solving the problem that the range hood cannot automatically change the current gear according to the flue exhaust situation, resulting in poor flexibility and convenience of the fan gear change, so that the range hood can exhaust smoke intelligently and bring better user experience.

[0063] In some embodiments, when a gear switching instruction triggered by a user is detected within a time interval, the default customary gear within the time interval is updated to the gear to be switched.

[0064] For example, the default custom gear is F, the time interval is (0 o'clock, 10 o'clock], and when a gear switching command triggered by the user is detected between 0 o'clock and 10 o'clock, it is determined that the gear to be switched is D; the default custom gear F in the time interval is updated to the gear to be switched D, so that the next time the user turns on the range hood between 0 o'clock and 10 o'clock, the fan operates according to the updated default custom gear D to generate the corresponding air volume.

[0065] In this embodiment, after the range hood is turned on, it automatically runs according to the user's default custom gear, based on the user's daily usage habits. The user does not need to manually adjust the gear of the range hood to the default custom gear after the range hood is turned on, thereby improving the compatibility of the user group. After the air volume is generated according to the user's default custom gear, the flue resistance generated when the fan runs according to the user's default custom gear is determined, and the candidate gear of the fan is determined based on the flue resistance; the fan is controlled to run according to the candidate gear to generate a candidate air volume, that is, on the basis of the air volume generated by the default custom gear, the air volume is dynamically adjusted in combination with the flue resistance to obtain the candidate air volume; then the smoke concentration is obtained, and when the smoke concentration is greater than the preset concentration, the smoke concentration is adjusted based on the candidate air volume and the preset Increasing the air volume value to determine the target air volume is equivalent to adjusting the candidate air volume again within a certain air volume range based on the candidate air volume to obtain the target air volume, and finally determining the target gear of the fan according to the target air volume, and controlling the fan to switch from the candidate gear to the target gear to operate, so as to achieve the air volume adjustment of the air volume generated by the default gear within a certain air volume range in combination with the flue resistance and the smoke concentration, and then realize automatic gear switching according to the air volume, so that the range hood can exhaust smoke intelligently, improve the flexibility, intelligence and convenience of the fan gear control of the range hood, solve the problem that users can only manually adjust the fan gear of the range hood based on experience, which is not intelligent and convenient enough, and bring users a better user experience.

[0066] The following is a further description of the range hood gear control method provided by the embodiment of the present invention with a specific example. In this embodiment, the range hood may include 4 gears. After the range hood is turned on, the automatic gear is turned on by default. The automatic gear may include 3 gear modes: mode 1, mode 2, and mode 3. The preset information may include first preset information, second preset information, and third preset information. The first preset information may include candidate air volumes corresponding to each flue resistance in mode 1, the second preset information may include candidate air volumes corresponding to each flue resistance in mode 2, and the third preset information may include candidate air volumes corresponding to each flue resistance in mode 3.

[0067] In mode 1, different air volumes are set to correspond to different flue resistances. For example, in mode 1, the air volume range stored in the first preset information is [A1, A2, ..., An], and the flue resistance range is [PA1, PA2, ..., PAn]. After the range hood is turned on, it operates according to the default custom gear to generate the corresponding air volume, and then determines the flue resistance PAn generated when the fan operates according to the user's default custom gear. Based on the flue resistance PAn, the preset information is queried to obtain the candidate air volume An corresponding to the flue resistance PAn, and the candidate gear of the fan is determined according to the candidate air volume An, and the fan is controlled to operate according to the candidate gear to generate the candidate air volume; then the smoke concentration is obtained, and when the smoke concentration is greater than the preset concentration, the candidate air volume An and the preset increase are increased. The air volume m is accumulated to obtain the adjusted air volume An+m. When the adjusted air volume An+m is greater than the maximum candidate air volume An, the maximum candidate air volume An is determined as the target air volume, the target gear of the fan is determined according to the target air volume, and the fan is controlled to switch from the candidate gear to the target gear, and then the operation of determining the flue resistance PAn generated when the fan runs according to the user's default customary gear is triggered; when the adjusted air volume An+m is not greater than the maximum candidate air volume An, the adjusted air volume An+m is determined as the target air volume, the target gear of the fan is determined according to the target air volume An+m, and the fan is controlled to switch from the candidate gear to the target gear, and then the operation of determining the flue resistance PAn generated when the fan runs according to the user's default customary gear is triggered.

[0068] Correspondingly, in mode 2, different air volumes are set to correspond to different flue resistances. For example, in mode 2, the air volume range stored in the second preset information is [B1, B2, ..., Bn], and the flue resistance range is [PB1, PB2, ..., PBn]. After the range hood is turned on, it operates according to the default custom gear to generate the corresponding air volume, and then determines the flue resistance PBn generated when the fan operates according to the user's default custom gear. Based on the flue resistance PBn, the preset information is queried to obtain the candidate air volume Bn corresponding to the flue resistance PBn, and the candidate gear of the fan is determined according to the candidate air volume Bn, and the fan is controlled to operate according to the candidate gear to generate the candidate air volume; then the smoke concentration is obtained, and when the smoke concentration is greater than the preset concentration, the candidate air volume Bn and the preset increase are compared. The air volume m is added for cumulative air volume to obtain the adjusted air volume Bn+m. When the adjusted air volume Bn+m is greater than the maximum candidate air volume Bn, the maximum candidate air volume Bn is determined as the target air volume, the target gear of the fan is determined according to the target air volume Bn, and the fan is controlled to switch from the candidate gear to the target gear, and then the operation of determining the flue resistance PBn generated when the fan runs according to the user's default customary gear is triggered; when the adjusted air volume Bn+m is not greater than the maximum candidate air volume Bn, the adjusted air volume Bn+m is determined as the target air volume, the target gear of the fan is determined according to the target air volume Bn+m, and the fan is controlled to switch from the candidate gear to the target gear, and then the operation of determining the flue resistance PBn generated when the fan runs according to the user's default customary gear is triggered.

[0069] Correspondingly, in mode 3, different air volumes are set to correspond to different flue resistances. For example, in mode 3, the air volume range stored in the third preset information is [C1, C2, ..., Cn], and the flue resistance range is [PC1, PC2, ..., PCn]. After the range hood is turned on, it operates according to the default custom gear to generate the corresponding air volume, and then determines the flue resistance PCn generated when the fan operates according to the user's default custom gear. Based on the flue resistance PCn, the preset information is queried to obtain the candidate air volume Cn corresponding to the flue resistance PCn, and the candidate gear of the fan is determined according to the candidate air volume Cn, and the fan is controlled to operate according to the candidate gear to generate the candidate air volume; then the smoke concentration is obtained, and when the smoke concentration is greater than the preset concentration, the candidate air volume Cn and the preset increase are compared. The air volume m is added for accumulating the air volume to obtain the adjusted air volume Cn+m. When the adjusted air volume Cn+m is greater than the maximum candidate air volume Cn, the maximum candidate air volume Cn is determined as the target air volume, the target gear of the fan is determined according to the target air volume Cn, and the fan is controlled to switch from the candidate gear to the target gear, and then the operation of determining the flue resistance PCn generated when the fan runs according to the user's default customary gear is triggered; when the adjusted air volume Cn+m is not greater than the maximum candidate air volume Cn, the adjusted air volume Cn+m is determined as the target air volume, the target gear of the fan is determined according to the target air volume Cn+m, and the fan is controlled to switch from the candidate gear to the target gear, and then the operation of determining the flue resistance PCn generated when the fan runs according to the user's default customary gear is triggered.

[0070] In this embodiment, after the range hood is turned on, mode 2 in the automatic gear is turned on by default, and the range hood automatically runs according to the user's default custom gear in mode 2, based on the user's daily usage habits. There is no need for the user to manually adjust the gear of the range hood to the default custom gear after the range hood is turned on, thereby improving the compatibility of the user group. After the air volume is generated according to the user's default custom gear, the flue resistance generated when the fan runs according to the user's default custom gear is determined, and a candidate gear of the fan is determined based on the flue resistance; the fan is controlled to run according to the candidate gear to generate a candidate air volume, that is, based on the air volume generated by the default custom gear, the air volume is dynamically adjusted in combination with the flue resistance to obtain the candidate air volume; then the smoke concentration is obtained, and when the smoke concentration is greater than the preset concentration, the smoke concentration is adjusted based on the smoke concentration. The target air volume is determined based on the candidate air volume and the preset increased air volume value, which is equivalent to adjusting the candidate air volume again within a certain air volume range based on the candidate air volume to obtain the target air volume, and finally determining the target gear of the fan according to the target air volume, and controlling the fan to switch from the candidate gear to the target gear for operation, so as to realize automatic adjustment of the air volume generated by the default customary gear within a certain air volume range in combination with the flue resistance and the smoke concentration, and then realize automatic gear switching according to the air volume, so that the range hood can exhaust smoke intelligently, improve the flexibility, intelligence and convenience of the fan gear control of the range hood, solve the problem that users can only manually adjust the fan gear of the range hood based on experience, which is not intelligent and convenient enough, and bring users a better user experience.

[0071] Optionally, when a mode switching instruction triggered by a user is detected within a time interval, the default custom mode within the time interval is updated to the mode to be switched.

[0072] For example, the default habit mode is mode 2, the time interval is (0 o'clock-10 o'clock]. When a mode switching command triggered by the user is detected between 0 o'clock and 10 o'clock, it is determined that the mode to be switched is mode 3; the default habit mode within the time interval is updated to the mode to be switched (mode 3), so that the next time the user turns on the range hood between 0 o'clock and 10 o'clock, the fan operates according to the updated default habit mode 3 to generate the corresponding air volume, reducing the user's manual adjustment and realizing the automatic mode switching function in the automatic gear.
