[0089] The present invention discloses an intelligent control method and device for oil fume exhaust of a range hood, which improves the reliability and accuracy of the oil fume exhaust control operation of the range hood, thereby improving the oil fume exhaust effect of the range hood, thereby enhancing the cooking experience of users.

[0090] Embodiment 1

[0091] See also Figure 2 , Figure 2 The figure is a flow chart of a method for intelligently controlling the exhaust of oil smoke from a range hood disclosed in an embodiment of the present invention. Optionally, the method can be implemented by a range hood control system, which can be integrated in the range hood or can exist independently of the range hood, or can be a local server or cloud server for processing the range hood control process, etc., which is not limited by the embodiment of the present invention. Figure 2 As shown, the intelligent control method for exhausting oil smoke of the range hood may include the following operations:

[0092] 101. Determine the oil fume exhaust demand parameters of the scene where the range hood is located, and determine the air watt parameters required for the range hood to exhaust the oil fume based on the oil fume exhaust demand parameters.

[0093] In the embodiment of the present invention, the fume exhaust requirement parameter may include an fume exhaust requirement parameter and / or an fume exhaust requirement type parameter. For example, the fume exhaust requirement is α mg / m 3 , the types of exhaust fume requirements include fine particulate matter, gaseous pollutants, etc. Specifically, the air watt parameter required by the range hood to exhaust fume can be understood as the power parameter required by the range hood to exhaust fume.

[0094] 102. Determine the smoke duct resistance parameters of the range hood, and determine the air volume control parameters of the range hood based on the smoke duct resistance parameters.

[0095] In the embodiment of the present invention, the smoke duct resistance parameter of the range hood can be understood as the flow resistance of oil smoke, gas, etc. temporarily stored in the smoke duct connected to the range hood, wherein, when the smoke duct resistance parameter is larger, a smaller air volume control parameter can be determined accordingly, and when the smoke duct resistance parameter is smaller, a larger air volume control parameter can be determined accordingly, so that no matter how large the smoke duct resistance is, a constant oil smoke exhaust effect can be achieved subsequently.

[0096] 103. Calculate the wind speed control parameter for the range hood according to the air watt parameter, the air volume control parameter and the preset oil fume exhaust calculation formula, and control the range hood to perform the oil fume exhaust operation according to the air volume control parameter and the wind speed control parameter.

[0097] In the embodiment of the present invention, the preset fume exhaust calculation formula can be: air watt parameter = K * air volume control parameter * wind speed control parameter, where K is a preset coefficient. It should be noted that the fume exhaust effect of the range hood does not only depend on the air volume or wind speed, but needs to rely on both to achieve a constant air watt value, that is, it needs to correspond to the perfect balance point between air volume and wind speed. For example, Figure 1 As shown, Figure 1 A schematic diagram of an intelligent control scenario for oil fume exhaust of a range hood disclosed in an embodiment of the present invention, wherein when it is determined that the oil fume exhaust demand of the scenario where the range hood is located is a, and the oil fume exhaust demand type parameter is fine particulate matter, at this time, based on the above parameters, the air watt parameter corresponding to the range hood is determined to be b; on the other hand, based on the smoke duct resistance parameter c, the air volume control parameter d is also determined, and then based on the air watt parameter b, the air volume control parameter d and the preset oil fume exhaust calculation formula, the wind speed control parameter can be calculated as: e=b / K / d, so that according to the wind speed control parameter e and the air volume control parameter d, the motor operation of the range hood and the flipping of the flap are controlled to realize the oil fume exhaust process of the range hood.

[0098] It can be seen that the implementation of the embodiment of the present invention can intelligently determine the air volume control parameters and the wind speed control parameters based on the oil fume exhaust demand parameters corresponding to the range hood, and then control the range hood to perform oil fume exhaust operations. In this way, based on the perfect balance point between the air volume control parameters and the wind speed control parameters, the reliability and accuracy of the oil fume exhaust control operation of the range hood are improved, thereby improving the oil fume exhaust effect of the range hood, thereby creating a healthy and safe cooking environment for users and enhancing the users' cooking experience.

[0099] In an optional embodiment, determining the smoke duct resistance parameter of the range hood in step 102 includes:

[0100] Determine the current usage of the smoke pipe connected to the range hood and smoke pipe parameters of the smoke pipe;

[0101] The smoke duct resistance parameters of the range hood are determined according to the current usage of the smoke duct and the smoke duct parameters.

[0102] In this optional embodiment, if Figure 1 As shown, the smoke pipe connected to the range hood a is generally connected to the smoke pipe of the range hood b of another user, and when the other user uses his own range hood b, the smoke exhausted by his range hood b may flow through the corresponding smoke pipe to the smoke pipe connected to the range hood a, thereby forming smoke pipe resistance. Optionally, the current usage includes the currently stored smoke emission amount parameters and / or smoke emission type parameters from other users, and the smoke pipe parameters include smoke pipe size parameters and / or smoke pipe shape parameters.

[0103] It can be seen that this optional embodiment can calculate the smoke duct resistance parameters based on the current usage of the smoke duct connected to the range hood and the smoke duct parameters of the smoke duct. This is conducive to improving the calculation reliability and accuracy of the smoke duct resistance parameters, and further conducive to improving the reliability and accuracy of determining the air volume control parameters of the range hood, thereby facilitating improving the subsequent reliability and accuracy of determining the wind speed control parameters, so as to achieve effective oil fume exhaust operation of the range hood.

[0104] In another optional embodiment, before determining the smoke duct resistance parameter of the range hood according to the current usage of the smoke duct and the smoke duct parameters in the above step, the method further includes:

[0105] Determine the air flow parameters of the external environment to which the smoke pipe is connected;

[0106] The air injection condition into the smoke pipe is determined according to the air flow parameters of the external environment.

[0107] Further, in this optional embodiment, the smoke duct resistance parameter of the range hood is determined according to the current use of the smoke duct and the smoke duct parameters, including:

[0108] The smoke duct resistance parameters of the range hood are determined according to the air injection situation, the current use situation of the smoke duct and the smoke duct parameters.

[0109] In this optional embodiment, the air flow parameter optionally includes at least one of an air flow direction parameter, an air flow volume parameter, and an air flow wind force parameter. It should be noted that the smoke pipe connected to the range hood is generally connected to the external environment to discharge oil smoke to the external environment. However, on the other hand, when the air flow of the external environment is relatively large, a certain amount of air will be injected into the smoke pipe accordingly, thereby causing smoke pipe resistance. Therefore, it is necessary to further determine the smoke pipe resistance parameter of the range hood in combination with the air flow conditions of the external environment.

[0110] It can be seen that this optional embodiment can further determine the smoke duct resistance parameters of the range hood in combination with the air infusion conditions caused by the external environment into the smoke duct. In this way, the comprehensiveness of the smoke duct resistance analysis of the range hood is improved, and then the reliability and accuracy of the determination of the smoke duct resistance parameters of the range hood are improved, thereby improving the subsequent reliability and accuracy of the determination of the air volume control parameters and the wind speed control parameters, so as to achieve a perfect balance between the two and achieve a constant air watt effect.

[0111] Embodiment 2

[0112] See also Figure 3 , Figure 3 The figure is a flow chart of a method for intelligently controlling the exhaust of oil smoke from a range hood disclosed in an embodiment of the present invention. Optionally, the method can be implemented by a range hood control system, which can be integrated in the range hood or can exist independently of the range hood, or can be a local server or cloud server for processing the range hood control process, etc., which is not limited by the embodiment of the present invention. Figure 3 As shown, the intelligent control method for exhausting oil smoke of the range hood may include the following operations:

[0113] 201. Determine an exhaust fume demand parameter of a scene where the range hood is located, and determine an air watt parameter required for the range hood to exhaust the fume based on the exhaust fume demand parameter.

[0114] 202. Determine a smoke duct resistance parameter of the range hood, and determine an air volume control parameter of the range hood based on the smoke duct resistance parameter.

[0115] 203. Calculate the wind speed control parameter for the range hood according to the air watt parameter, the air volume control parameter and the preset oil fume exhaust calculation formula.

[0116] 204. Determine motor operation parameters and flap flipping parameters of the range hood according to the air volume control parameters, and control the motor of the range hood to perform a fume extraction operation according to the motor operation parameters and control the flap of the range hood to perform a flipping operation according to the flap flipping parameters.

[0117] In an embodiment of the present invention, optionally, the motor operating parameters may include motor operating power parameters, motor operating voltage parameters, motor operating current parameters, etc., and the flap flipping parameters may include flap flipping direction parameters, flap flipping rate parameters, flap flipping angle parameters, etc., wherein, through the flipping operation of the flap, the size of the smoke intake port of the range hood can be intelligently controlled.

[0118] 205. During the flipping operation, the wind speed parameter at the smoke inlet of the range hood is monitored, and when the monitored wind speed parameter matches the wind speed control parameter, a flipping stop operation is performed on the flap.

[0119] In the embodiment of the present invention, specifically, the wind speed parameter at the inlet is associated with the change in the size of the inlet during the flipping process: when the inlet is getting bigger, the wind speed parameter is getting smaller, and when the inlet is getting smaller, the wind speed parameter is getting larger. When the flip plate is flipped and stopped, the air volume and wind speed of the range hood reach a perfect balance point, achieving a constant air watt effect.

[0120] In the embodiment of the present invention, for other descriptions of step 201 to step 203, please refer to the detailed description of step 101 to step 103 in the first embodiment, and the embodiment of the present invention will not be repeated.

[0121] It can be seen that the implementation of the embodiment of the present invention can monitor the wind speed parameters at the smoke outlet during the process of controlling the motor operation and flipping of the range hood, and then stop flipping when the wind speed parameters match the wind speed control parameters. This is conducive to achieving a perfect balance between the air volume and wind speed of the range hood, and further conducive to achieving a constant air watt effect, thereby facilitating the realization of a constant oil fume exhaust effect of the range hood, so as to discharge the oil fume in the scene where the range hood is located as quickly and as much as possible.

[0122] In an optional embodiment, before determining the fume exhaust requirement parameter of the scene where the range hood is located in step 201, the method further includes:

[0123] Determine the oil fume source parameters of the scene where the range hood is located, and determine the oil fume exhaust demand corresponding to the scene based on the oil fume source parameters;

[0124] According to the oil fume exhaust demand, determining whether the oil fume exhaust demand is greater than or equal to a preset oil fume exhaust demand threshold;

[0125] When it is determined that the oil fume exhaust requirement is greater than or equal to the oil fume exhaust requirement threshold, an operation of determining an oil fume exhaust requirement parameter of the scene where the range hood is located is performed.

[0126] In this optional embodiment, for example, when the oil fume in the scene where the range hood is located comes from a kettle that is boiling water, since the oil fume generated by the kettle is generally water mist and the amount of water mist is small, at this time, it can be determined that the oil fume exhaust demand is less than the preset oil fume exhaust demand threshold, and there is no need to perform the subsequent operation of determining the oil fume exhaust demand parameters of the scene where the range hood is located; and when the oil fume in the scene where the range hood is located comes from a frying pan that is in a cooking state, since the oil fume generated by the frying pan is generally fine particulate matter / gaseous pollutants and the amount of oil fume is large, at this time, it can be determined that the oil fume exhaust demand is greater than or equal to the preset oil fume exhaust demand threshold, and it is necessary to perform the subsequent operation of determining the oil fume exhaust demand parameters of the scene where the range hood is located, thereby controlling the range hood to perform the oil fume exhaust operation.

[0127] It can be seen that this optional embodiment can intelligently determine whether the oil fume exhaust demand is greater than or equal to the preset oil fume exhaust demand threshold based on the oil fume source parameters of the scene where the range hood is located, and then determine the oil fume exhaust demand parameters of the range hood when the determination result is yes. This is conducive to improving the reliability and accuracy of the threshold determination operation of the oil fume exhaust demand of the range hood, and further conducive to improving the reliability, accuracy and effectiveness of determining the oil fume exhaust demand parameters of the range hood, thereby helping to improve the reliability, accuracy and effectiveness of the subsequent control of the range hood.

[0128] In another optional embodiment, before determining the oil fume exhaust requirement corresponding to the scene according to the oil fume source parameter in the above step, the method further includes:

[0129] Determine the oil smoke sensitivity parameters of the target person in the scene;

[0130] According to the oil fume source parameters and the oil fume sensitivity parameters of the target personnel, the first impact of the oil fume in the scene on the target personnel is predicted;

[0131] Determine, according to the first impact situation, a first impact degree corresponding to the first impact situation, and judge whether the first impact degree is greater than or equal to a preset first impact degree threshold;

[0132] When it is determined that the first impact degree is greater than or equal to the first impact degree threshold, determining the oil fume exhaust demand corresponding to the scene according to the oil fume source parameter and the first impact situation;

[0133] When it is determined that the first influence degree is less than the first influence degree threshold, the oil fume exhaust requirement corresponding to the scene is determined according to the oil fume source parameter.

[0134] In this optional embodiment, the oil fume sensitivity parameter optionally includes an oil fume sensitivity type parameter and / or an oil fume sensitivity degree parameter. Further optionally, the first impact condition caused to the target person (the target person may be a person within a certain range from the range hood) includes a physiological impact condition and / or a psychological impact condition caused to the target person. For example, when the water mist produced by a kettle that is boiling water causes the target person to sneeze and form sensitive symptoms, at this time, it can be determined that the first impact degree is greater than or equal to the first impact degree threshold, and then the oil fume exhaust requirement corresponding to the scene needs to be determined based on the oil fume source parameter and the first impact condition (the oil fume exhaust requirement degree can be adjusted upward accordingly).

[0135] Further, as an optional implementation, before determining the oil fume exhaust demand corresponding to the scene according to the oil fume source parameter in the above step, the method further includes:

[0136] Determine item parameters of target items in the scene;

[0137] Predict the secondary impact of the oil smoke in the scene on the target object based on the oil smoke source parameters and the object parameters of the target object;

[0138] Determine, according to the second impact situation, a second impact degree corresponding to the second impact situation, and judge whether the second impact degree is greater than or equal to a preset second impact degree threshold;

[0139] When it is determined that the second impact degree is greater than or equal to the second impact degree threshold, the oil fume exhaust requirement corresponding to the scene is determined according to the oil fume source parameter and the second impact situation;

[0140] When it is determined that the second influence degree is less than the second influence degree threshold, the oil fume exhaust requirement corresponding to the scene is determined according to the oil fume source parameter.

[0141] In this optional embodiment, the object parameters may include object type parameters and / or object location parameters. Further optionally, the second impact on the target object (the target object may be an object within a certain range from the range hood) may include an oil fume stain impact and / or an odor impact on the target object. For example, when the water mist generated by a kettle that is boiling water causes water stains on the target object and damages the target object, then it can be determined that the first impact is greater than or equal to the first impact threshold, and then the oil fume exhaust requirement corresponding to the scene needs to be determined based on the oil fume source parameters and the second impact (the oil fume exhaust requirement can be adjusted upward accordingly).

[0142] It can be seen that this optional embodiment can perform corresponding impact threshold judgment operations based on the first impact of the oil fume in the scene where the range hood is located on the target person, and the second impact on the target object, and then determine the oil fume exhaust demand corresponding to the scene. This is conducive to improving the comprehensiveness of the determination of the oil fume exhaust demand corresponding to the scene, and then to improving the reliability and accuracy of the determination of the oil fume exhaust demand corresponding to the scene, which is conducive to improving the effectiveness of the subsequent determination of the oil fume exhaust demand parameters for the scene, so as to achieve the effectiveness of the oil fume exhaust operation of the range hood.

[0144] See also Figure 4 , Figure 4 Schematic diagram of the structure of an intelligent control device for exhausting oil smoke of a range hood disclosed in an embodiment of the present invention. Figure 4 As shown, the intelligent control device for exhausting oil smoke of the range hood may include:

[0145] The first determination module 301 is used to determine the exhaust demand parameter of the scene where the range hood is located, and determine the air watt parameter required for the range hood to exhaust the oil fume according to the exhaust demand parameter;

[0146] The second determination module 302 is used to determine the smoke pipe resistance parameter of the range hood;

[0147] The first determination module 301 is further used to determine the air volume control parameter of the range hood according to the smoke pipe resistance parameter;

[0148] The calculation module 303 is used to calculate the wind speed control parameter for the range hood according to the air watt parameter, the air volume control parameter and the preset oil fume exhaust calculation formula;

[0149] The control module 304 is used to control the range hood to perform the fume exhaust operation according to the air volume control parameter and the wind speed control parameter.

[0150] In the embodiment of the present invention, the oil fume exhaust requirement parameter includes an oil fume exhaust requirement quantity parameter and / or an oil fume exhaust requirement type parameter.

[0151] It can be seen that implementation Figure 4 The described intelligent control device for oil fume exhaust of the range hood can intelligently determine the air volume control parameters and the wind speed control parameters based on the oil fume exhaust demand parameters corresponding to the range hood, and then control the range hood to perform oil fume exhaust operation. In this way, based on the perfect balance point between the air volume control parameters and the wind speed control parameters, the reliability and accuracy of the oil fume exhaust control operation of the range hood are improved, thereby improving the oil fume exhaust effect of the range hood, thereby creating a healthy and safe cooking environment for users and enhancing the users' cooking experience.

[0152] In an optional embodiment, the control module 304 controls the range hood to perform the fume exhaust operation according to the air volume control parameter and the wind speed control parameter in the following manner:

[0154] During the flipping operation, the wind speed parameter at the smoke inlet of the range hood is monitored, and when the monitored wind speed parameter matches the wind speed control parameter, the flipping stop operation is performed on the flap.

[0155] It can be seen that implementation Figure 5 The described intelligent control device for exhaust of range hoods can monitor the wind speed parameters at the smoke outlet while controlling the operation of the motor and the flipping of the flap of the range hood, and then stop flipping when the wind speed parameters match the wind speed control parameters. This is conducive to achieving a perfect balance between the air volume and wind speed of the range hood, and then conducive to achieving a constant air watt effect, thereby conducive to achieving a constant exhaust effect of the range hood, so as to discharge the smoke in the scene where the range hood is located as quickly and as much as possible.

[0157] Determine the current usage of the smoke pipe connected to the range hood and smoke pipe parameters of the smoke pipe;

[0158] The smoke duct resistance parameters of the range hood are determined according to the current usage of the smoke duct and the smoke duct parameters.

[0159] In this optional embodiment, the current usage includes currently stored oil fume emission parameters and / or oil fume emission type parameters from other users, and the smoke pipe parameters include smoke pipe size parameters and / or smoke pipe shape parameters.

[0160] It can be seen that implementation Figure 5 The described intelligent control device for oil fume exhaust of the range hood can calculate the smoke duct resistance parameters based on the current usage of the smoke duct connected to the range hood and the smoke duct parameters of the smoke duct. This is conducive to improving the calculation reliability and accuracy of the smoke duct resistance parameters, and further conducive to improving the reliability and accuracy of determining the air volume control parameters of the range hood, thereby facilitating improving the subsequent reliability and accuracy of determining the wind speed control parameters, so as to achieve effective oil fume exhaust operation of the range hood.

[0161] In yet another optional embodiment, the second determining module 302 determines the smoke pipe resistance parameter of the range hood in a manner that specifically includes:

[0163] According to the air flow parameters of the external environment, determine the air injection into the smoke pipe;

[0164] The second determining module 302 determines the smoke pipe resistance parameter of the range hood according to the current use of the smoke pipe and the smoke pipe parameters, specifically including:

[0165] The smoke duct resistance parameters of the range hood are determined according to the air injection situation, the current use situation of the smoke duct and the smoke duct parameters.

[0166] In this optional embodiment, the air flow parameter includes at least one of an air flow direction parameter, an air flow volume parameter, and an air flow wind force parameter.

[0167] It can be seen that implementation Figure 5 The described intelligent control device for exhaust of range hoods can further determine the resistance parameters of the range hood duct in combination with the air infusion conditions caused by the external environment into the duct. In this way, the comprehensiveness of the analysis of the duct resistance of the range hood is improved, thereby improving the reliability and accuracy of the determination of the duct resistance parameters of the range hood, thereby improving the reliability and accuracy of the subsequent determination of the air volume control parameters and the wind speed control parameters, so as to achieve a perfect balance between the two and achieve a constant air watt effect.

[0168] In yet another optional embodiment, the first determining module 301 is further configured to:

[0170] The device also includes:

[0171] The judgment module 305 is used to judge whether the oil fume exhaust requirement is greater than or equal to a preset oil fume exhaust requirement threshold according to the oil fume exhaust requirement;

[0172] The first determination module 301 is further used to execute the operation of determining the oil fume exhaust requirement parameter of the scene where the range hood is located when the determination module 305 determines that the oil fume exhaust requirement is greater than or equal to the oil fume exhaust requirement threshold.

[0173] It can be seen that implementation Figure 5The described intelligent control device for oil fume exhaust of the range hood can intelligently determine whether the oil fume exhaust demand is greater than or equal to a preset oil fume exhaust demand threshold based on the oil fume source parameters of the scene where the range hood is located, and then determine the oil fume exhaust demand parameters of the range hood when the determination result is yes. This is conducive to improving the reliability and accuracy of the threshold determination operation of the oil fume exhaust demand of the range hood, and further conducive to improving the reliability, accuracy and effectiveness of determining the oil fume exhaust demand parameters of the range hood, thereby facilitating improving the reliability, accuracy and effectiveness of subsequent control of the range hood.

[0174] In yet another optional embodiment, the first determining module 301 is further configured to:

[0175] Before determining the degree of exhaust demand for the scene according to the fume source parameter, determine the fume sensitivity parameter of the target person in the scene; the fume sensitivity parameter includes an fume sensitivity type parameter and / or an fume sensitivity degree parameter;

[0177] The first prediction module 306 is used to predict the first impact of the oil smoke in the scene on the target person according to the oil smoke source parameter and the oil smoke sensitivity parameter of the target person; the first impact on the target person includes the physiological impact and / or psychological impact on the target person;

[0178] The first determining module 301 is further configured to determine a first impact degree corresponding to the first impact situation according to the first impact situation;

[0179] The judging module 305 is further configured to judge whether the first influence degree is greater than or equal to a preset first influence degree threshold;

[0181] Further, as an optional implementation manner, the first determining module 301 is further configured to:

[0182] Before determining the exhaust demand for the corresponding scene according to the fume source parameter, determine the object parameters of the target object in the scene; the object parameters include object type parameters and / or object location parameters;

[0183] The device also includes:

[0184] The second prediction module 307 is used to predict the second impact of the oil smoke in the scene on the target object according to the oil smoke source parameter and the object parameter of the target object; the second impact on the target object includes the oil smoke stain impact and / or odor impact on the target object;

[0185] The first determining module 301 is further configured to determine a second impact degree corresponding to the second impact situation according to the second impact situation;

[0186] The judging module 305 is further configured to judge whether the second influence degree is greater than or equal to a preset second influence degree threshold;
