[0091] The present invention discloses an automatic noise reduction method and device for a range hood, which is beneficial to improving the reliability and accuracy of the noise reduction adjustment and determination operation of the range hood, and further beneficial to improving the reliability, accuracy and effectiveness of the noise reduction adjustment operation of the range hood, thereby facilitating reducing the impact of noise on the user's hearing.

[0092] Embodiment 1

[0093] See also Figure 2 , Figure 2 1 is a flow chart of an automatic noise reduction method for a range hood disclosed in an embodiment of the present invention. Optionally, the method can be implemented by a range hood noise reduction system, which can be integrated in the range hood or exist independently of the range hood, or can be a local server or cloud server for processing the range hood noise reduction process, etc., which is not limited by the embodiment of the present invention. Figure 2 As shown, the automatic noise reduction method of the range hood may include the following operations:

[0094] 101. When the range hood is in operation, determine current noise parameters of the range hood, and determine whether a noise reduction adjustment operation needs to be performed on the range hood based on the current noise parameters of the range hood.

[0095] In an embodiment of the present invention, determining whether it is necessary to perform a noise reduction adjustment operation on the range hood can be understood as determining whether the range hood will have a greater negative impact on the user's hearing. When the judgment result is yes, it is necessary to perform a noise reduction adjustment operation on the range hood. Otherwise, it is not necessary to perform a noise reduction adjustment operation on the range hood.

[0096] 102. When it is determined that a noise reduction adjustment operation needs to be performed on the range hood, a target adjustment parameter of the range hood is determined, and the noise reduction adjustment operation is performed on the range hood according to the target adjustment parameter.

[0097] In the embodiment of the present invention, the target adjustment parameters may include operation adjustment parameters of the motor of the range hood and / or flip adjustment parameters of the flap. Further, the operation adjustment parameters of the motor may include operation power adjustment parameters, operation voltage adjustment parameters, operation current adjustment parameters, etc., and the flip adjustment parameters of the flap may include flip angle adjustment parameters, flip rate adjustment parameters, flip direction adjustment parameters, etc.

[0098] Further, according to the target adjustment parameter, a noise reduction adjustment operation is performed on the range hood, including:

[0099] According to the operation adjustment parameters of the motor, an operation adjustment operation is performed on the motor and / or according to the flip adjustment parameters of the flap, a flip adjustment operation is performed on the flap, so as to perform a noise reduction adjustment operation on the range hood.

[0100] Among them, the flip adjustment operation of the flap can adjust the size of the smoke outlet of the range hood. When the motor is in a fixed operating state, the flip adjustment of the flap makes the size of the smoke outlet half of the maximum value, which is the lowest noise state of the motor in this operating state.

[0101] It can be seen that the implementation of the embodiment of the present invention can intelligently determine whether to perform noise reduction adjustment on the range hood based on the current noise parameters of the range hood, and when the determination result is yes, perform noise reduction adjustment on the range hood. This is beneficial to improving the reliability and accuracy of the noise reduction adjustment determination operation on the range hood, and further beneficial to improving the reliability, accuracy and effectiveness of the noise reduction adjustment operation on the range hood, thereby helping to reduce the impact of noise on the user's hearing.

[0102] In an optional embodiment, determining the target adjustment parameters of the range hood in step 102 includes:

[0103] Determine a first noise parameter at a place where a motor of the range hood makes a sound and a second noise parameter at a place where a flap makes a sound;

[0104] Determine the influence degree of the noise factor corresponding to the place where the motor makes a sound according to the first noise parameter, and determine the influence degree of the noise factor corresponding to the place where the flap makes a sound according to the second noise parameter;

[0105] According to the influence degree of the noise factor corresponding to the motor sound source and the influence degree of the noise factor corresponding to the flap sound source, the sound source to be adjusted whose corresponding noise factor influence degree is greater than or equal to a preset influence degree threshold is determined from the motor sound source and the flap sound source;

[0106] When the sound source to be adjusted includes the sound source of the motor, determining the operation adjustment parameters for the motor of the range hood according to the first noise parameter of the sound source of the motor;

[0107] When the sound-emitting location to be adjusted includes a flap sound-emitting location, a flipping adjustment parameter for the flap of the range hood is determined according to the second noise parameter of the flap sound-emitting location.

[0108] In this optional embodiment, the first noise parameter and the second noise parameter may include a noise tone type parameter and / or a noise magnitude parameter at the corresponding sound source. Figure 1 As shown, Figure 1 A schematic diagram of an automatic noise reduction scenario of a range hood disclosed in an embodiment of the present invention, wherein when it is determined that the first noise parameter at the motor sound source is a and the second noise parameter at the flap sound source is b, it can be determined that the influence degree of the noise factor corresponding to the motor sound source is 85%, and the influence degree of the noise factor corresponding to the flap sound source is 92%. Subsequently, based on the preset influence degree threshold of 90%, it can be determined that the sound source to be adjusted is the flap sound source, that is, the sound at the flap will cause a greater negative auditory impact on nearby target personnel. At this time, the flip adjustment parameter of the flap can be further determined based on the second noise parameter at the flap sound source, so that by adjusting the flip of the flap, the size of the smoking port can be made to reach half of the maximum value as much as possible to effectively reduce noise.

[0109] It can be seen that this optional embodiment can determine the degree of influence of the noise factor at the corresponding sound source based on the first noise parameter at the motor sound source and the second noise parameter at the flap sound source, and perform the corresponding influence degree threshold judgment operation, so as to determine the operation adjustment parameters for the motor or the flip adjustment parameters of the flap. In this way, the intelligent noise analysis at the corresponding sound source of the range hood is reflected, the reliability and accuracy of determining the degree of influence of the noise factor at the corresponding sound source is improved, and then the reliability, accuracy and effectiveness of the target adjustment parameters are improved, thereby improving the reliability, accuracy and effectiveness of the noise reduction operation at the motor / flip sound source of the range hood, so as to enhance the user experience of the range hood.

Optionally, the method can be implemented by a range hood noise reduction system, which can be integrated in the range hood or exist independently of the range hood, or can be a local server or cloud server for processing the range hood noise reduction process, etc., which is not limited by the embodiment of the present invention. Figure 3 As shown, the automatic noise reduction method of the range hood may include the following operations:

[0112] 201. When the range hood is in operation, determine current noise parameters of the range hood, and determine whether a noise reduction adjustment operation needs to be performed on the range hood based on the current noise parameters of the range hood.

[0113] 202. When it is determined that a noise reduction adjustment operation needs to be performed on the range hood, a target adjustment parameter of the range hood is determined.

[0114] 203. According to the target adjustment parameters, predict the exhaust fume control parameters of the range hood after adjustment.

[0115] In an embodiment of the present invention, optionally, the adjusted rear exhaust fume control parameters include adjusted air volume control parameters and / or adjusted wind speed control parameters, wherein the adjusted air volume control parameters are associated with the adjusted operating parameters of the motor and the adjusted flipping parameters of the flap, while the adjusted wind speed control parameters are associated with the adjusted flipping parameters of the flap.

[0116] 204. According to the adjusted rear exhaust fume control parameters, predict the adjusted rear exhaust fume parameters of the range hood.

[0117] In the embodiment of the present invention, it is predicted what type of oil smoke and how much oil smoke the range hood can exhaust after noise reduction. Optionally, adjusting the rear exhaust oil smoke parameter includes adjusting the rear exhaust oil smoke volume parameter and / or adjusting the rear exhaust oil smoke type parameter.

[0118] 205. According to the adjusted oil fume exhaust parameters, predict whether the adjusted range hood meets the preset oil fume exhaust conditions.

[0119] In the embodiment of the present invention, it is predicted whether the type and amount of oil fume exhausted by the range hood after noise reduction can meet the preset oil fume exhaust requirement.

[0120] 206. When it is predicted that the range hood meets the oil fume exhaust condition, a step of performing a noise reduction adjustment operation on the range hood according to the target adjustment parameter is executed.

[0121] In the embodiment of the present invention, for other descriptions of step 201, step 202 and step 206, please refer to the detailed description of step 101-step 102 in the first embodiment, and the embodiment of the present invention will not be repeated.

[0122] It can be seen that the implementation of the embodiment of the present invention can predict the adjusted oil fume parameters of the range hood based on the target adjustment parameters, and then predict whether the adjusted range hood can meet the oil fume exhaust conditions based on the adjusted oil fume exhaust parameters, so as to perform the corresponding noise reduction adjustment operation when the prediction result is yes. In this way, the reliability and accuracy of the oil fume exhaust condition determination operation of the adjusted range hood can be improved, and then the reliability and accuracy of the noise reduction adjustment operation of the range hood can be improved, so as to ensure that the range hood can meet the use requirements while achieving the noise reduction effect, thereby enhancing the user experience.

[0123] In an optional embodiment, the step 205 of predicting whether the adjusted range hood meets the preset range hood exhaust condition according to the adjusted range hood exhaust parameter includes:

[0124] Determine object parameters of a target object in the scene where the range hood is located;

[0125] Determine the oil fume exhaust requirement parameters of the target object according to the object parameters of the target object, and judge whether the adjusted oil fume exhaust parameters can meet the oil fume exhaust requirement conditions of the target object according to the adjusted oil fume exhaust parameters and the oil fume exhaust requirement parameters;

[0126] When it is determined that the oil fume exhaust requirement condition of the target object can be met, it is determined that the adjusted range hood meets the preset oil fume exhaust condition;

[0127] When it is determined that the oil fume exhaust requirement of the target object cannot be met, it is determined that the adjusted range hood does not meet the oil fume exhaust condition.

[0128] In this optional embodiment, the object parameters of the target object optionally include the position parameters of the target person, the oil fume sensitivity parameters of the target person, the position parameters of the target object, and the type parameters of the target object. For example, if the target person is a person who is more sensitive to fine particulate matter, then it can be determined that the target person has a need to exhaust fine particulate matter, and when the predicted adjusted oil fume exhaust parameters indicate that the adjusted range hood can exhaust fine particulate matter, it can be determined that the oil fume exhaust demand conditions of the target object can be met, that is, it is determined that the adjusted range hood meets the preset oil fume exhaust conditions, and the subsequent noise reduction operation can be performed normally.

[0129] It can be seen that this optional embodiment can determine the oil fume exhaust demand parameters based on the object parameters of the target object, and then determine whether the adjusted oil fume exhaust parameters can meet the oil fume exhaust demand conditions of the target object, thereby realizing the determination operation of the oil fume exhaust conditions of the adjusted range hood. This is conducive to improving the reliability and accuracy of the determination operation of whether the adjusted oil fume exhaust parameters can meet the oil fume exhaust demand conditions of the target object, and further conducive to improving the reliability, accuracy and effectiveness of the determination operation of the oil fume exhaust conditions of the adjusted range hood, thereby conducive to ensuring that the range hood can meet the expected usage requirements after noise reduction.

[0130] In another optional embodiment, the method further comprises:

[0131] When it is predicted that the range hood does not meet the oil fume exhaust condition, the oil fume exhaust control demand parameter of the range hood is determined according to the oil fume exhaust demand parameter of the target object;

[0132] According to the oil fume exhaust control demand parameters of the range hood, the oil fume exhaust adjustment operation is performed on the range hood, and a noise reminder instruction is issued, so that the target personnel can perform noise protection operations according to the noise reminder instruction.

[0133] In this optional embodiment, the exhaust fume control requirement parameters may include motor operation control requirement parameters and / or flap flip control requirement parameters. Further optionally, the noise protection operation may include being slightly away from the range hood or wearing noise-proof protective gear, etc. Specifically, when the range hood is subjected to noise reduction, its exhaust fume effect may be reduced to a certain extent. At this time, the exhaust fume requirement parameters of the target object may be determined first, and the exhaust fume adjustment operation of the range hood may be performed based on the exhaust fume requirement parameters, that is, the exhaust fume requirement of the target object may be ensured first, and then a corresponding noise reduction plan may be made for the target person.

[0134] It can be seen that this optional embodiment can automatically adjust the range hood's oil fume exhaust operation based on the target object's oil fume exhaust demand parameters, and emit noise to issue a reminder instruction to remind the target person to perform noise protection. In this way, it can ensure that the range hood's oil fume exhaust operation can meet the target object's oil fume exhaust demand, and can also reduce the hearing damage caused by noise to the target person through noise protection reminders, thereby creating a healthy and safe cooking environment for the target person.

[0135] In yet another optional embodiment, the step 201 of determining whether it is necessary to perform a noise reduction adjustment operation on the range hood according to the current noise parameter of the range hood includes:

[0136] Determine the noise tolerance parameters for people in the scene where the range hood is located;

[0137] According to the noise tolerance parameter of the personnel and the current noise parameter of the range hood, it is determined whether the tolerance of the personnel to the noise emitted by the range hood is greater than or equal to a preset tolerance threshold;

[0138] When it is determined that the tolerance level is greater than or equal to the tolerance level threshold, it is determined that a noise reduction adjustment operation needs to be performed on the range hood;

[0139] When it is determined that the tolerance level is less than the tolerance level threshold, it is determined that there is no need to perform the noise reduction adjustment operation on the range hood.

[0140] In this optional embodiment, the noise tolerance parameter optionally includes a noise tolerance size parameter and / or a noise tolerance sound type parameter. Specifically, the noise tolerance parameter of a person can be determined based on the psychological change parameter and / or physiological change parameter of the person when hearing noise of corresponding decibel size or sound type, and when the psychological change fluctuation of the person is large and / or the physiological change fluctuation is large when hearing the noise, it can be considered that the noise tolerance of the person has reached the limit.

[0141] It can be seen that this optional embodiment can intelligently determine whether the person's tolerance for the noise emitted by the range hood has reached its limit based on the person's noise tolerance parameters and the current noise parameters of the range hood. If so, the range hood needs to be adjusted for noise reduction. This will help improve the reliability and accuracy of the operation of determining the need for noise reduction adjustment of the range hood, and further help improve the effectiveness of the noise reduction adjustment operation of the range hood, thereby helping to enhance the corresponding person's user experience of the range hood.

[0142] In yet another optional embodiment, the above step of determining whether the tolerance of the person to the noise emitted by the range hood is greater than or equal to a preset tolerance threshold according to the noise tolerance parameter of the person and the current noise parameter of the range hood includes:

[0143] Determine the personnel's current target parameters;

[0144] According to the current target parameters of the personnel and the current noise parameters of the range hood, the noise reception of the personnel to the range hood is determined;

[0145] According to the noise reception situation, determine the noise reception parameter corresponding to the noise reception situation, and judge whether the noise reception parameter is greater than or equal to the noise tolerance parameter of the personnel;

[0146] When it is determined that the noise receiving parameter is greater than or equal to the noise tolerance parameter of the person, it is determined that the tolerance level of the person to the noise emitted by the range hood is greater than or equal to a preset tolerance level threshold;

[0147] When it is determined that the noise reception parameter is less than the noise tolerance parameter of the person, it is determined that the tolerance level of the person to the noise emitted by the range hood is less than the tolerance level threshold.

[0148] In this optional embodiment, optionally, the current target parameter of the person includes the current distance parameter between the person and the range hood and / or the current noise protection parameter of the person, wherein the current noise protection parameter includes a noise protection equipment type parameter and / or a noise protection strictness parameter. Further optionally, the noise reception condition includes at least one of a noise direction reception condition, a noise magnitude reception condition, and a noise sound type reception condition. For example, when the person is close to the range hood, it can be determined that the noise volume of the range hood received by the person will be relatively loud, and then it can be further determined that the noise emitted by the range hood will exceed the noise tolerance range of the person, that is, the range hood needs to be subsequently adjusted for noise reduction.

[0149] It can be seen that this optional embodiment can determine the noise reception situation of the personnel to the range hood according to the current target parameters of the personnel, and compare the noise reception parameters corresponding to the noise reception situation with the noise tolerance parameters of the personnel, so as to realize the threshold judgment operation of the personnel's tolerance level to the noise emitted by the range hood. In this way, the reliability and accuracy of the analysis of the personnel's noise reception situation can be improved, and then the reliability and accuracy of the threshold judgment operation of the personnel's tolerance level to the noise emitted by the range hood can be improved, so as to improve the effectiveness of the subsequent noise reduction adjustment demand judgment operation of the range hood.

In this way, the intelligent noise analysis at the corresponding sound-emitting point of the range hood is reflected, the reliability and accuracy of determining the degree of influence of the noise factor at the corresponding sound-emitting point is improved, and then the reliability, accuracy and effectiveness of the target adjustment parameters are improved, thereby improving the reliability, accuracy and effectiveness of the noise reduction operation at the motor / flip sound-emitting point of the range hood, so as to enhance the user experience of the range hood.
