Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of the present disclosure.

[0042] Various exemplary embodiments, features, and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. The same reference numbers in the drawings represent functionally similar or the same elements. Although various aspects of the embodiments are illustrated in the drawings, the drawings are not necessarily drawn to scale unless specifically indicated.

[0043] The word "exemplary" is used herein in the sense of being an example, illustration, or demonstration. Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments.

[0044] The term "and / or", used in the present document, only describes the association relationship of the associated objects, and indicates that there can be three relationships, for example, A and / or B can represent the following three cases: A exists alone, A and B exist simultaneously, and B exists alone.

[0045] In addition, in order to better illustrate the present disclosure, numerous specific details are given in the specific embodiments below. Those skilled in the art should understand that the present disclosure can also be implemented without certain specific details. In some examples, methods, means, elements and circuits that are well known to those skilled in the art are not described in detail in order to highlight the main idea of the present disclosure.

[0046] The range hood is a kitchen appliance for purifying the kitchen environment, and the range hood is provided with a fan. Among them, the fan of the range hood is one of the core components of the range hood, mainly used to suck the oil fume generated in the kitchen into the inside of the range hood, and separate the oil fume through oil fume separation technology, and finally discharge the purified air outside. The performance of the fan of the range hood will directly affect the effect of the range hood on sucking oil fume and the noise condition. Generally speaking, the larger the air volume of the fan, the stronger the suction, which can quickly suck away the oil fume in the kitchen. However, too large air volume will also produce a lot of noise, thereby affecting the user's experience.

[0047] The traditional range hood usually adopts the way of gradually increasing the fan speed to reach the set air volume or set speed during operation. The process of gradually increasing the speed takes a long time and produces a lot of noise. In addition, the set air volume or set speed to be reached by the range hood is usually corresponding to the preset gear, and cannot be adjusted based on the actual working condition. For example, after being used for a period of time, the accumulation of oil stains on the check valve and the increase of resistance in the flue during the cooking peak period will increase the resistance of opening the check valve. If the range hood fan still follows the fixed speed-up mode, it will cause the check valve to be opened for too long, affecting the discharge of oil fume and also producing a lot of noise, affecting the user experience.

[0048] In order to solve the above technical problems, the present disclosure provides a range hood air volume control method, which adjusts the starting acceleration and starting air volume of the range hood fan by obtaining target parameters such as the use time of the range hood, the time period in which the starting time is located, and the flue resistance. By adjusting the starting acceleration and starting air volume, the change rate of the fan speed is dynamically adjusted while the change amount of the range hood fan speed is adjusted, the time for the range hood to reach the predetermined air volume or predetermined speed is reduced, the discharge of oil fume is more smooth, the noise generated during use is also reduced, and the user experience is improved.

[0049] Figure 1 A flowchart of an oil fume extractor air volume control method according to an embodiment of the present disclosure is shown in FIG. 1. As shown in FIG. 1, the method comprises the following steps. Figure 1

[0050] S101: Obtain a target parameter of the oil fume extractor, the target parameter comprising at least one of a use duration, a time period in which the start time is located, and a duct resistance; wherein the use duration indicates a time interval between the start time and a last oil fume extractor cleaning time.

[0051] Further, before the step S101, the method further comprises: receiving a start instruction of the oil fume extractor; the start instruction being triggered by a user and aiming to control the oil fume extractor to start. Specifically, the start instruction can be triggered by the user based on a start button or touch key provided on the oil fume extractor; in a specific implementation, the start button or touch key is usually provided on a control panel of the oil fume extractor.

[0052] Specifically, in the case where the target parameter is the use duration, the step S101 comprises: obtaining a time at which the start instruction is received and a last oil fume extractor cleaning time, taking the time at which the start instruction is received as the start time; and determining the use duration according to the start time and the last oil fume extractor cleaning time.

[0053] Specifically, the last oil fume extractor cleaning time is a time at which a last oil fume extractor cleaning is completed; in an alternative implementation, the oil fume extractor cleaning time is generated based on a cleaning operation of the user. For example, an input device receives the cleaning operation of the user, generates the oil fume extractor cleaning time based on a time at which the cleaning operation of the user is completed, and sends the oil fume extractor cleaning time to an oil fume extractor control device; wherein the input device is an input operation component or a voice input component, the input operation component comprising a touch screen and / or at least one button, for example, the input operation component is an operation panel comprising at least one button, and the input device is optionally located on an oil fume extractor control panel or a smart terminal. Alternatively, when the input device is located on the smart terminal, the user can input the oil fume extractor cleaning time through a terminal application or a small program, etc.

[0054] The smart terminal refers to an electronic device with wireless connection function, which can be connected to the oil fume extractor as above through the Internet, or can be directly connected to the oil fume extractor as above through Bluetooth, WiFi, etc. In some embodiments, the smart terminal includes but is not limited to mobile devices, computers, etc. The mobile device may, for example, include a mobile phone, a smart home device, a wearable device, a smart mobile device, a virtual reality device, etc., or any combination thereof, wherein the wearable device may, for example, include a smart watch, a smart bracelet, etc.

[0055] ​Optionally, in another alternative embodiment, the last hood cleaning time can also be recorded automatically by the hood. For example, when the hood control device receives a cleaning instruction, the time when the cleaning ends is recorded as the hood cleaning time by the hood control device, and the cleaning instruction can be triggered by a cleaning button or touch key provided on the hood.

[0056] For another example, the oil pollution detection device can be a pressure sensor.

[0057] In a specific implementation, the last hood cleaning time can be stored in a local database of the hood or a server database.

[0058] In some other embodiments, when the target parameter is the time period in which the start time is located, the step S101 includes: obtaining the time when the start instruction is received, taking the time when the start instruction is received as the start time, and determining the time period in which the start time is located.

[0059] In some other embodiments, when the target parameter is the air duct resistance, the step S101 includes: obtaining the air duct resistance in the exhaust passage.

[0060] Here, the air duct resistance can be determined by a wind pressure sensor installed in the exhaust passage of the hood.

[0061] S102: adjusting the operation parameter of the hood fan based on the target parameter; the operation parameter at least includes: start acceleration and start air volume.

[0062] In the embodiment, the start acceleration and start air volume of the hood fan during operation are determined by the obtained target parameters such as the use length of the hood, the time period in which the start time is located, and the air duct resistance. In this way, the effect of dynamically adjusting the operation parameter of the fan under different working conditions is achieved, and by adjusting the start acceleration and start air volume, the change rate of the rotation speed of the hood fan and the change amount of the rotation speed of the fan are realized, the time for the hood to reach a predetermined air volume or rotation speed is reduced, the exhaust of oil fume is more smooth, the noise generated during use is reduced, and the user experience is improved.

[0063] Further, Figure 2 A flowchart for adjusting the operation parameter of the hood fan based on a target parameter according to an embodiment of the present disclosure is shown. As shown in Figure 2 S102 includes:

[0064] S1021a: in the case that the target parameter is the use time length, determining the starting acceleration and the starting air volume corresponding to the use time length based on the use time length and a first correspondence relationship;

[0065] Specifically, the first correspondence relationship indicates the correspondence relationship between the use time length and the starting acceleration and the use time length and the starting air volume, the use time length is proportional to the starting acceleration, and the use time length is proportional to the starting air volume.

[0066] The first correspondence relationship has been pre-stored in the local database of the range hood or in a server database; in some embodiments, the first correspondence relationship can also be updated based on the cooking habits of the user.

[0067] S1022a: adjusting the operation parameter of the range hood fan based on the starting acceleration and the starting air volume corresponding to the use time length;

[0068] Specifically, as the use time increases, the oil dirt on the check valve of the range hood also increases, and the resistance required to open the check valve also increases. At this time, by increasing the starting air volume of the range hood fan, the gap between the starting air volume of the range hood and the target air volume is reduced, and by increasing the starting acceleration, the rate at which the range hood reaches the target air volume is improved. In this way, the time for the range hood to reach the predetermined air volume or predetermined speed is reduced, making the exhaust of oil fume more smooth, while also reducing the noise generated during use and improving the user experience.

[0069] As the use time decreases, that is, the time from the last range hood cleaning is shorter, the oil dirt on the check valve of the range hood is less, and the resistance required to open the check valve decreases. At this time, by reducing the starting air volume and the starting acceleration of the range hood fan, the range hood is prevented from working with excessive air volume, which causes unnecessary loss and energy waste.

[0070] Further, Figure 3 Another flowchart for adjusting the operation parameter of the range hood fan based on a target parameter is shown according to an embodiment of the present disclosure; as Figure 3 As shown in the figure, step S102 includes:

[0071] S1021b: in the case that the target parameter is the time period in which the starting time is located, determining the starting acceleration and the starting air volume corresponding to the time period in which the starting time is located based on the time period in which the starting time is located and a second correspondence relationship; wherein the second correspondence relationship indicates the correspondence relationship between different time periods and the starting acceleration and the correspondence relationship between different time periods and the starting air volume.

[0072] Further, before the step S1021b, the method further comprises:

[0073] receiving at least one time period and a start-up acceleration and a start-up air volume corresponding to the at least one time period;

[0074] generating the second relationship based on the at least one time period, the start-up acceleration and the start-up air volume corresponding to the at least one time.

[0075] Specifically, in an embodiment, the at least one time period and the start-up acceleration and the start-up air volume corresponding to the at least one time period can be input by a user through the input device.

[0076] In other embodiments, the at least one time period and the start-up acceleration and the start-up air volume corresponding to the at least one time period can also be generated by a server based on a user's cooking time period and a start-up acceleration and a start-up air volume corresponding to the cooking time period, etc. after machine learning.

[0077] In the present embodiment, the second corresponding relationship is input by a user; wherein the time length of the at least one time period can be the same or different. The user divides a time period into different time periods, which can be one day or one week, without specific limitation here.

[0078] For example, a user can divide one day into 8 time periods of the same length, i.e. every three hours into a time period, such as 0:00 to 3:00, 3:00 to 6:00, 6:00 to 9:00, etc.

[0079] For another example, a user can also divide one day into time periods of different lengths, such as: 0:00 to 6:30, 6:00 to 9:30, 9:30 to 10:30, 10:30 to 12:30, 12:30 to 18:00, 18:00 to 20:00, 20:00 to 24:00.

[0080] For another example, a user can also divide one day into time periods of different lengths, such as: 0:00 to 6:30, 6:00 to 9:30, 9:30 to 10:30, 10:30 to 12:30, 12:30 to 18:00, 18:00 to 20:00, 20:00 to 24:00.

[0081] S1022b: adjusting the operating parameters of the range hood fan based on the start-up acceleration and the start-up air volume corresponding to the time period in which the start-up time is located.

[0082] In specific implementation, the start acceleration and the start air volume corresponding to the different time periods can be custom values set by the user based on personal habits, can be reference values generated by the range hood based on the different time periods divided by the user, or can be values personalized by the user based on the reference values.

[0083] The second correspondence is set according to the cooking demand of the user, and after the setting is completed, the range hood determines the operation parameter according to the second correspondence and the start time of the range hood, so that the range hood provides the user with more accurate and user-demand-matching start acceleration and start air volume in the working process, improves the user experience, and can also avoid generating air volume greater than the actual cooking demand, thereby saving energy.

[0084] Further, the method further comprises:

[0085] In a case where the at least one time period is determined to be a cooking peak period, first prompt information is generated; the first prompt information is used to remind to increase the start acceleration and the start air volume corresponding to the at least one time period;

[0086] In a case where the at least one time period is determined to be not a cooking peak period, second prompt information is generated; the second prompt information is used to remind to reduce the start acceleration and the start air volume corresponding to the at least one time period.

[0087] Specifically, the cooking peak period can be a time interval set in advance based on big data, or can be determined based on the flue resistance of a public flue in a region where the user is located.

[0088] The first prompt information and the second prompt information can be text information, can be voice information, or can be a combination of the two, which is not specifically limited here.

[0089] In the embodiment, the first prompt information and the second prompt information can be displayed when the second correspondence is generated, to provide a reference for the user to set the start acceleration and the start air volume in the second correspondence. Specifically, when the user sets the operation parameter for the divided different time periods, if the time period is a cooking peak period, the first prompt information is generated and displayed to remind the user to increase the start acceleration and the start air volume corresponding to the time period; if the time period is not a cooking peak period, the second prompt information is generated and displayed to remind the user to reduce the start acceleration and the start air volume corresponding to the time period; in this way, by displaying the first prompt information and the second prompt information, the user can be helped to set more appropriate range hood operation parameters.

[0090] In some embodiments, the first prompt information and the second prompt information can also be displayed in the actual cooking process of the user. In the cooking process, if it is determined that the current time period is a cooking peak period and the running parameter set for the current time period is too small, the first prompt information is generated to remind the user to increase the start-up acceleration and the start-up air volume; if it is determined that the current time period is not a cooking peak period and the running parameter set for the current time period is too large, the second prompt information is generated to remind the user to reduce the start-up acceleration and the start-up air volume.

[0091] In this way, the user is reminded to dynamically adjust the start-up acceleration and the start-up air volume according to the actual working condition, so as to avoid the situation that the air volume of the range hood is too large or the fan takes a long time to speed up and generates a large noise due to the small start-up acceleration and the start-up air volume.

[0092] Further, Figure 4 Another flowchart for adjusting the running parameter of the range hood fan based on the target parameter is shown according to an embodiment of the present disclosure; as shown in Figure 4 As shown in step S102, step S102 includes:

[0093] S1021c: in the case that the target parameter is the air duct resistance, the start-up acceleration and the start-up air volume corresponding to the air duct resistance are determined based on the air duct resistance.

[0094] The air duct resistance is determined by an air pressure sensor installed in the smoke exhaust passage of the range hood.

[0095] Specifically, the air pressure sensor can detect the air duct resistance in the public flue in real time. For example, when the cooking peak period, the air duct resistance will be large, and the air volume required to open the check valve will also increase; when it is not the cooking peak period or the number of cooks is small, the air duct resistance will decrease, and the air volume required to open the check valve will also decrease.

[0096] The start-up acceleration and the start-up air volume corresponding to the air duct resistance can be determined based on the obtained real-time air duct resistance and a third corresponding relationship, the third corresponding relationship indicating the corresponding relationship between the air duct resistance and the start-up acceleration and the air duct resistance and the start-up air volume.

[0097] S1022c: the running parameter of the range hood fan is adjusted based on the start-up acceleration and the start-up air volume corresponding to the air duct resistance.

[0098] In this embodiment, the air duct resistance in the flue is detected in real time, and the running parameter of the range hood fan is dynamically adjusted based on the air duct resistance, so that the current fan running parameter in each scene is automatically adjusted in real time according to the scene, so that the start-up air volume and the start-up acceleration of the range hood are always adapted to the corresponding scene, and the oil smoke absorption effect is improved.

[0099] In some embodiments, the method further comprises setting weights of the use duration, the time period in which the start time is located, and the air duct resistance, and in the case that multiple target parameters of the use duration, the time period in which the start time is located, and the air duct resistance are obtained, then after determining multiple operating parameters based on the multiple target parameters, the operating parameters of the range hood fan that are finally adjusted are determined according to the weights of different target parameters that are set and the multiple operating parameters.

[0100] For example, the weight of the use duration is denoted by P1, the weight of the time period in which the start time is located is denoted by P2, the weight of the air duct resistance is denoted by P3, the start acceleration corresponding to the operating parameter of the use duration is denoted by A1, the start acceleration corresponding to the operating parameter of the time period in which the start time is located is denoted by A2, the start acceleration corresponding to the operating parameter of the air duct resistance is denoted by A3, and the start acceleration of the range hood fan is denoted by A.

[0101] In step S101, the target parameters obtained include the use duration, the time period in which the start time is located, and the air duct resistance, and then based on the target parameters, the start acceleration A of the range hood fan is adjusted as A=A1*P1+A2*P2+A3*P3.

[0102] The process of adjusting the start air volume of the range hood fan is similar to the process of determining the start acceleration, which will not be described here.

[0103] In this embodiment, the start acceleration and the start air volume of the range hood fan during operation are determined based on the target parameters of the use duration, the time period in which the start time is located, and the air duct resistance of the range hood obtained, so that the range hood is in a more intelligent working gear. By adjusting the start acceleration to control the change rate of the speed of the range hood fan, and by adjusting the start air volume of the range hood to reduce the time for the range hood to reach the required air volume, the exhaust of the oil fume is more smooth, the noise generated during use is reduced, and the user experience is improved.

[0104] Please refer to Figure 5 which shows a block diagram of a range hood air volume control device provided by an embodiment of the present disclosure. The range hood air volume control device has the functions of the above-mentioned method examples, which can be implemented by hardware or by corresponding software executed by hardware. The range hood air volume control device can include:

[0105] The obtaining module 510 is configured to obtain target parameters of the range hood, and the target parameters include at least one of the following: a use duration, a time period in which a start time is located, and an air duct resistance.
