Description

Technical Field

[0001] This invention relates to the field of range hood technology, and in particular to a control method, device, electronic equipment, and readable storage medium for a range hood. Background Technology

[0002] During operation, range hoods often experience fumes escaping due to the limited size of their air inlets. This is especially true for side-draft range hoods, where the inlet size is matched to the grease filter size. When there is excessive fumes, some grease cannot be drawn into the range hood in time and escapes to the sides. The fixed inlet angle and the inability to adjust the distance from the stove also affect the fume extraction effect. Additionally, some fumes may escape from the space between the opened panel glass and the fume collection hood.

[0003] However, existing intelligent control methods for range hoods generally only adjust the range hood's speed setting and motor rotation speed, but cannot adjust the grease filter mechanism. Therefore, current intelligent control methods cannot adjust the operation of the grease filter mechanism according to actual conditions, resulting in grease escaping and a poor user experience.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Currently, during operation, range hoods often experience smoke escape due to limitations in the size of their air inlets. This is especially true for side-draft range hoods, where the inlet size is matched to the grease filter size. When there is excessive smoke, some grease cannot be drawn into the range hood in time and escapes to the sides. The fixed inlet angle and the inability to adjust the distance from the stove also affect the smoke extraction effect. Additionally, some smoke escapes from the space between the opened panel glass and the smoke collection hood.

[0033] However, existing intelligent control methods for range hoods generally only adjust the range hood's speed setting and motor rotation speed, but cannot adjust the grease filter mechanism. Therefore, current intelligent control methods cannot adjust the operation of the grease filter mechanism according to actual conditions, resulting in grease escaping and a poor user experience.

[0034] Based on this, the present invention provides a control method, device, electronic device and readable storage medium for a range hood, which can intelligently control the operation of the range hood's motor and oil filter mechanism, thereby preventing the escape of oil fumes and improving the user experience.

[0035] To facilitate understanding of this embodiment, a control method for a range hood disclosed in this embodiment of the invention will first be described in detail.

[0036] Example 1:

[0037] This invention provides a control method for a range hood, see below. Figure 1 The flowchart shown illustrates a control method for a range hood, which includes the following steps:

[0038] Step S102: Obtain the first oil fume concentration outside the range hood, the second oil fume concentration inside the range hood, and the third oil fume concentration in the kitchen space where the range hood is located.

[0039] In this embodiment, the range hood is installed in the kitchen space, and the oil fume concentration at different locations of the range hood and the kitchen space can be obtained separately. For example, multiple oil fume concentration detection devices can be set up to detect the oil fume concentration in the designated area.

[0040] The oil fume concentration outside the range hood can be called the first oil fume concentration, which can be represented by the letter X; the oil fume concentration inside the range hood can be called the second oil fume concentration, which can be represented by the letter E; and the oil fume concentration in the kitchen space where the range hood is located can be called the third oil fume concentration, which can be represented by the letter F.

[0041] Step S104: Control the operation of the oil filter mechanism of the range hood based on the first oil fume concentration, the third oil fume concentration and the preset threshold.

[0042] Currently, range hoods have multiple operating speeds, corresponding to different motor speeds and airflow rates. After setting the initial operating speed, increasing the motor speed raises the operating speed, thereby reducing the internal second oil fume concentration E and improving smoke extraction. The left-right movement and outward rotation of the oil filter mechanism enhances the range hood's smoke collection ability, reducing the external first oil fume concentration X. Furthermore, the third oil fume concentration F in the kitchen space is affected by the range hood's smoke extraction and collection capabilities, and is therefore related to the left-right movement and outward rotation of the oil filter mechanism, as well as the operating speed of the range hood.

[0043] Step S106: Control the operation of the range hood motor based on the second oil fume concentration, the third oil fume concentration, and the threshold.

[0044] Therefore, in this embodiment, the operation of the range hood's oil filter mechanism can be controlled based on the first oil fume concentration X, the third oil fume concentration G, and a preset threshold. In this embodiment, the operation of the range hood's oil filter mechanism can also be controlled based on the second oil fume concentration E, the third oil fume concentration G, and a preset threshold. This achieves the goal of simultaneously controlling the operation of the range hood's motor and oil filter mechanism, thereby preventing oil fume escape and improving the user experience.

[0045] This invention provides a control method for a range hood, which can control the operation of the range hood's motor and oil filter mechanism. The oil filter operation controls the concentration of oil fumes outside the range hood, and the motor operation controls the concentration of oil fumes inside the range hood cavity (smoke collection cavity). This can prevent oil fumes from escaping and accumulating inside the range hood, thereby improving the range hood's smoke extraction effect and enhancing the user experience.

[0046] Example 2:

[0047] This embodiment provides another method for controlling a range hood, which is implemented based on the above embodiment, such as... Figure 2 The flowchart shows another control method for a range hood. The control method for the range hood in this embodiment includes the following steps:

[0048] Step S202: Obtain the first oil fume concentration outside the range hood, the second oil fume concentration inside the range hood, and the third oil fume concentration in the kitchen space where the range hood is located, all collected by the oil fume concentration detection device.

[0049] In this embodiment, the first oil fume concentration outside the range hood can be determined by obtaining the average value of the oil fume concentration at at least three locations on the fume collection hood. For example, the oil fume concentration at at least three locations on the fume collection hood can be collected using an oil fume concentration detection device, and the average value of the oil fume concentration at the at least three locations can be used as the first oil fume concentration outside the range hood.

[0050] Specifically, in this embodiment, the oil fume concentration at a first position on the left side of the range hood, the oil fume concentration at a second position on the right side of the range hood, and the oil fume concentration at a third position on the top of the range hood can be collected by an oil fume concentration detection device; the average value of the oil fume concentration at the first position, the second position, and the third position is taken as the first oil fume concentration on the outside of the range hood.

[0051] This embodiment provides an intelligent control system for a range hood. It can detect the escape of cooking fumes from the left, right, and top (space between the panel glass and the range hood) of the fume collection hood during operation using fume concentration detection devices. Therefore, this embodiment can install a fume concentration detection device at each of the three locations (left, right, and top of the fume collection hood) to monitor the fume concentration at each location in real time. These three locations are referred to as the first location fume concentration A, the second location fume concentration B, and the third location fume concentration C, respectively. The average value of the first location fume concentration A, the second location fume concentration B, and the third location fume concentration C is taken as the first fume concentration X outside the range hood.

[0052] Specifically, in this embodiment, the oil fume concentration at the position between the filter screen and the centrifugal fan of the range hood can be collected by an oil fume concentration detection device, which is used as the second oil fume concentration inside the range hood.

[0053] This embodiment can include the filter and centrifugal fan inside the range hood. Position between Set up an oil fume concentration detection device to detect the oil fume concentration at the position between the filter screen and the centrifugal fan of the range hood in real time, and use this device as the second oil fume concentration E inside the range hood.

[0054] Specifically, in this embodiment, the third oil fume concentration in the kitchen space where the range hood is located can be collected by an oil fume concentration detection device.

[0055] In this embodiment, an oil fume concentration detection device can be installed in the kitchen space to detect the third oil fume concentration F in the kitchen space where the range hood is located in real time.

[0056] Step S204: Control the operation of the oil filter mechanism of the range hood based on the first oil fume concentration, the third oil fume concentration and a preset threshold; control the operation of the motor of the range hood based on the second oil fume concentration, the third oil fume concentration and the threshold.

[0057] In this embodiment, the operation of the range hood's oil filter mechanism and motor can be intelligently controlled based on the actual oil fume generation during the cooking process using pre-set control logic.

[0058] Specifically, if the third oil fume concentration is less than a preset first threshold and the third oil fume concentration is less than the first oil fume concentration; based on the oil fume concentration at the first position, the second position, and the third position, the target position oil fume concentration, which is greater than the third oil fume concentration, controls the range hood to perform a target operation, wherein the target operation is used to increase the air intake area and / or bring the air inlet closer to the oil fume source through the oil mesh mechanism; after the range hood performs the target operation for a preset duration, the ratio of the target position oil fume concentration to the third oil fume concentration is determined; if the ratio is greater than or equal to a preset second threshold, the range hood is controlled to continue performing the target operation; if the ratio is less than the second threshold, the range hood is controlled to stop performing the target operation.

[0059] The purpose of the range hood's target operation is to increase the air intake area and / or bring the air inlet closer to the source of cooking fumes through the oil filter mechanism. This can be understood as: the range hood's target operation aims to increase the air intake area through the oil filter mechanism; or, the range hood's target operation aims to bring the air inlet closer to the source of cooking fumes; or, the range hood's target operation aims to both increase the air intake area through the oil filter mechanism and bring the air inlet closer to the source of cooking fumes.

[0060] Specifically, the aforementioned target operation includes at least one of the following: opening the oil filter mechanism of the range hood, opening at least one air inlet of the range hood, or rotating the oil filter mechanism of the range hood. Opening the oil filter mechanism can involve unfolding at least a partially retracted oil filter, or spreading out partially overlapping oil filters; the method of opening the oil filter is not limited, and its main function is to increase the air intake area of ​​the oil filter. Opening at least one air inlet of the range hood can involve opening one air inlet; or opening two air inlets, which can be on the same plane or on two different planes, to absorb fumes from different locations on the range hood and reduce the escape rate of fumes; or opening three air inlets, which can be on the same plane, or at least two air inlets on the same plane, or all three air inlets on different planes, to absorb fumes from different locations on the range hood and further reduce the escape rate of fumes.

[0061] In this embodiment, one or more of the following can be executed simultaneously: opening the oil filter mechanism of the range hood, opening at least one air inlet of the range hood, or rotating the oil filter mechanism of the range hood. Opening the oil filter mechanism and opening at least one air inlet of the range hood are used to increase the air intake area, while rotating the oil filter mechanism is used to bring the air inlet closer to the source of cooking fumes.

[0062] By opening the oil filter mechanism and / or at least one air inlet of the range hood, the air intake area of ​​the range hood can be increased; by rotating the oil filter mechanism, the opened air inlet can be aligned with the source of oil fumes, thereby improving the smoke collection effect of the range hood.

[0063] The overall third oil fume concentration F within the kitchen space is a key parameter in this embodiment. An expected value G is set as the first threshold, and the third oil fume concentration F must remain F < G. Regarding the first oil fume concentration X outside the range hood and the third oil fume concentration F within the kitchen space, the actual operation of the range hood in this embodiment can be divided into the following situations:

[0064] Case 1: The third oil fume concentration F in the kitchen space is less than the first threshold G.

[0065] If the third oil fume concentration F in the kitchen space is less than the first oil fume concentration X outside the range hood, it indicates that the overall smoke collection effect of the range hood is poor, and more oil fumes escape, which will increase the third oil fume concentration F in the kitchen space. Therefore, it is necessary to control the opening or rotation of the oil filter mechanism of the range hood.

[0066] See Figure 3 The diagram shown is a schematic of a range hood control system. Figure 3 The oil fume concentrations at three locations on the outside of the range hood (i.e., oil fume concentration A at the first location, oil fume concentration B at the second location, and oil fume concentration C at the third location) correspond to the movement of the left oil filter, the movement of the right oil filter, and the overall flipping of the oil filter, respectively.

[0067] Since the operating principles are the same, for the sake of simplicity in the diagram, Figure 3 The oil fume concentration at three locations on the outside of the range hood is simplified as the oil fume concentration at the left position, and the corresponding movement of the left oil filter.

[0068] Specifically, if the target location's oil fume concentration is greater than the third oil fume concentration, including the first location's oil fume concentration, the oil filter mechanism on the left side of the range hood's smoke collection hood is controlled to open or rotate; if the target location's oil fume concentration is greater than the third oil fume concentration, including the second location's oil fume concentration, the oil filter mechanism on the right side of the range hood's smoke collection hood is controlled to open or rotate; if the target location's oil fume concentration is greater than the third oil fume concentration, including the third location's oil fume concentration, the oil filter mechanism on the top of the range hood's smoke collection hood is controlled to open or rotate.

[0069] That is, the first position corresponds to the left side of the range hood's smoke collection hood, the second position corresponds to the right side of the range hood's smoke collection hood, and the third position corresponds to the top of the range hood's smoke collection hood.

[0070] like Figure 3As shown, if the ratio of the oil fume concentration at the first position, the second position, or the third position to the third oil fume concentration is less than 1, no adjustment is made. If the ratio is greater than 1, the oil filter mechanism at the corresponding position of the oil fume concentration can be opened or rotated to improve the smoke collection capacity. For example, if the ratio of the oil fume concentration A at the first position to the third oil fume concentration F is greater than 1, the inner oil filter on the left side of the range hood is adjusted to move outward, expanding the left air intake surface.

[0071] like Figure 3 As shown, if the oil mesh moves or rotates for a preset period of time, the ratios of the oil fume concentrations at the first, second, and third positions (left, right, and top) of the range hood in the kitchen space to the oil fume concentration at the third position (F) of the kitchen space can be determined.

[0072] like Figure 3 As shown, the oil fume concentration at the target location can be defined as the oil fume concentration when the ratio is greater than or equal to the second threshold (which can be 0.6). The oil mesh at the corresponding location will remain open. If the ratio is less than 0.6, the oil mesh mechanism at the corresponding location will be closed.

[0073] Specifically, if the ratio is less than the second threshold, the oil filter mechanism of the range hood is kept open or rotated; after the oil filter mechanism of the range hood has been kept open or rotated for a preset duration, the ratio of the target location oil fume concentration to the third oil fume concentration is redefined; if the redefined ratio is less than the second threshold, the oil filter mechanism of the range hood is closed.

[0074] For example: If the ratio of the oil fume concentration A at the first position to the oil fume concentration F at the third position is less than 0.6, the oil filter mechanism on the left side of the range hood's smoke collection hood will remain open for 3 minutes. If the ratio is still less than 0.6 after 3 minutes, the oil filter mechanism on the left side of the range hood's smoke collection hood will be closed.

[0075] Under the premise of Case 1, the operation control of the range hood motor is as follows: if the third oil fume concentration is less than the preset first threshold and the third oil fume concentration is less than or equal to the second oil fume concentration, the operating level of the range hood motor is not adjusted; if the third oil fume concentration is less than the first threshold and the third oil fume concentration is greater than the second oil fume concentration, the operation of the range hood motor is controlled based on the ratio of the second oil fume concentration to the third oil fume concentration.

[0076] like Figure 3 As shown, if the third oil fume concentration F in the kitchen space is less than or equal to the second oil fume concentration E inside the range hood, although the second concentration E inside the range hood is relatively large, the smoke extraction effect is already sufficient to ensure that the third oil fume concentration F in the kitchen space is less than the first threshold G. Therefore, the range hood speed does not need to be adjusted, i.e., the motor speed does not need to be adjusted.

[0077] like Figure 3 As shown, if the third oil fume concentration F in the kitchen space is greater than the second oil fume concentration E inside the range hood, it indicates that the range hood's smoke extraction effect is in surplus, and the operating speed of the range hood motor can be adjusted.

[0078] Specifically, in this embodiment, the ratio of the second oil fume concentration to the third oil fume concentration can be determined; if the ratio is less than a preset third threshold, the operating level of the range hood motor is reduced; if the ratio is greater than or equal to the third threshold, the operating level of the range hood motor is not adjusted.

[0079] like Figure 3 As shown, if the ratio of the second oil fume concentration E inside the range hood to the third oil fume concentration F in the kitchen space is less than the third threshold (which can be 0.6), and this ratio can be maintained below the third threshold for 3 minutes, then the operating level of the range hood motor can be reduced to lower energy consumption and noise levels, thus improving the cooking experience. If the ratio of the second oil fume concentration E inside the range hood to the third oil fume concentration F in the kitchen space is greater than or equal to the third threshold, then the operating level of the range hood motor does not need to be adjusted.

[0080] Case 2: The third oil fume concentration F in the kitchen space is greater than or equal to the first threshold G.

[0081] Specifically, if the third oil fume concentration is greater than or equal to the preset first threshold, the oil filter mechanism of the range hood is controlled to open or rotate to the maximum value; after the oil filter mechanism of the range hood has been open or rotated to the maximum value for a preset duration, the operation of the oil filter mechanism and motor of the range hood is controlled based on the first threshold, the third oil fume concentration and the fourth threshold.

[0082] If the third oil fume concentration F in the kitchen space is greater than or equal to the first threshold G, then oil fumes accumulate inside the kitchen. To ensure a good cooking experience, it is essential to improve the overall fume collection effect of the appliance. Figure 3 As shown, the oil mesh mechanisms on the left and right sides can be moved outwards at this time, and the oil mesh mechanisms can be flipped outwards until the maximum value is reached, maintaining this state for a preset duration (which can be 5 minutes).

[0083] Specifically, if the third oil fume concentration is less than the first threshold and the third oil fume concentration is greater than or equal to the fourth threshold, the oil filter mechanism of the range hood is controlled to remain open or rotate to the maximum value; if the third oil fume concentration is greater than or equal to the first threshold, the operating level of the range hood motor is increased; if the third oil fume concentration is less than the fourth threshold, the oil filter mechanism of the range hood is controlled to open or rotate based on the target position oil fume concentration which is greater than the third oil fume concentration among the oil fume concentrations at the first, second, and third positions.

[0084] like Figure 3As shown, during operation, if the third oil fume concentration F in the kitchen space decreases and remains at the first threshold G > the third oil fume concentration F > the fourth threshold (which can be 0.6G), then the left and right oil filters will continue to move outward and flip outward until the maximum value is reached, without adjustment. If the third oil fume concentration F in the kitchen space is less than the fourth threshold 0.6G during operation, then this state will be maintained for another 3 minutes. If the third oil fume concentration F still remains less than the fourth threshold 0.6G, then the oil filter mechanism of the range hood can be adjusted according to the oil filter and overall machine operation mode adjustment method in situation 1. For example, the target position oil fume concentration that is greater than the third oil fume concentration among the first, second, and third position oil fume concentrations can be used to control the opening or rotation of the range hood's oil filter mechanism.

[0085] like Figure 3 As shown, if the oil filters on the left and right sides move outward and the oil filters flip outward until they reach their maximum value, and the third oil fume concentration F in the kitchen space does not decrease significantly or cannot be reduced to below the first threshold G (i.e., the third oil fume concentration F is greater than or equal to the first threshold G), then the operating speed of the range hood motor needs to be increased.

[0086] For example, the range hood can be operated for 3 minutes after each increase in the gear level. If the third oil fume concentration F in the kitchen space still cannot be reduced to below the first threshold G, the gear level can be increased further. If the third oil fume concentration F in the kitchen space decreases after increasing the gear level and remains at the first threshold G > the third oil fume concentration F > the fourth threshold 0.6G, the range hood can be maintained at that gear level, and the left and right oil filters will continue to move outward and rotate outward until the maximum value is reached. If the third oil fume concentration F in the kitchen space decreases to < the fourth threshold 0.6G after increasing the gear level, the range hood can continue to operate for 3 minutes. If the third oil fume concentration F still remains < the fourth threshold 0.6G, the range hood can be adjusted according to the oil filter and overall machine operation gear adjustment method in Case 1. For example, the oil filter mechanism of the range hood can be opened or rotated based on the target position oil fume concentration which is greater than the third oil fume concentration among the first, second, and third position oil fume concentrations.

[0087] The method provided in this embodiment of the invention can control the operation of the range hood's oil filter mechanism based on a first oil fume concentration outside the range hood, a third oil fume concentration in the kitchen space where the range hood is located, and a preset threshold; and control the operation of the range hood's motor based on a second oil fume concentration inside the range hood, a third oil fume concentration in the kitchen space where the range hood is located, and a threshold. This control of the range hood's motor and oil filter mechanism prevents oil fume escape and improves the user experience.

[0088] Example 3:

[0089] Corresponding to the above method embodiments, this invention provides a control device for a range hood, see [link to relevant documentation]. Figure 4 The diagram shows a structural schematic of a control device for a range hood. The control device includes:

[0090] The oil fume concentration acquisition module 41 is used to acquire the first oil fume concentration outside the range hood, the second oil fume concentration inside the range hood, and the third oil fume concentration in the kitchen space where the range hood is set.

[0091] The oil mesh mechanism operation control module 42 is used to control the operation of the oil mesh mechanism of the range hood based on the first oil fume concentration, the third oil fume concentration and a preset threshold.

[0092] The motor operation control module 43 is used to control the operation of the range hood motor based on the second oil fume concentration, the third oil fume concentration, and a threshold.

[0093] This invention provides a control device for a range hood, which can control the operation of the range hood's motor and oil filter mechanism. By controlling the operation of the oil filter, the concentration of oil fumes outside the range hood is controlled, and by controlling the operation of the motor, the concentration of oil fumes inside the range hood cavity is controlled. This can prevent oil fume escape and internal oil fume accumulation, thereby improving the range hood's smoke extraction effect and enhancing the user experience.

[0094] The aforementioned oil fume concentration acquisition module is used to collect oil fume concentration at at least three locations on the smoke collection hood of the range hood through an oil fume concentration detection device, and to take the average value of the oil fume concentration at the at least three locations as the first oil fume concentration on the outside of the range hood.

[0095] The aforementioned oil fume concentration acquisition module is used to collect the oil fume concentration at a first position on the left side of the range hood, the oil fume concentration at a second position on the right side of the range hood, and the oil fume concentration at a third position on the top of the range hood through an oil fume concentration detection device; and to take the average value of the oil fume concentration at the first position, the second position, and the third position as the first oil fume concentration on the outside of the range hood.

[0096] The aforementioned oil fume concentration acquisition module is used to collect the oil fume concentration at the position between the filter screen and the centrifugal fan of the range hood through an oil fume concentration detection device, as the second oil fume concentration inside the range hood; the aforementioned oil fume concentration acquisition module is also used to collect the third oil fume concentration in the kitchen space where the range hood is located through an oil fume concentration detection device.

[0097] The aforementioned oil mesh mechanism operation control module is used to control the range hood to perform a target operation if the third oil fume concentration is less than a preset first threshold and the third oil fume concentration is less than the first oil fume concentration; based on the target position oil fume concentration, which is greater than the third oil fume concentration among the first, second, and third position oil fume concentrations, the target operation is used to increase the air intake area and / or bring the air inlet closer to the oil fume source through the oil mesh mechanism; after the range hood has been performing the target operation for a preset duration, the ratio of the target position oil fume concentration to the third oil fume concentration is determined; if the ratio is greater than or equal to a preset second threshold, the range hood is controlled to continue performing the target operation; if the ratio is less than the second threshold, the range hood is controlled to stop performing the target operation.

[0098] The aforementioned target operation includes at least one of the following: opening the oil filter mechanism of the range hood, opening at least one air inlet of the range hood, or rotating the oil filter mechanism of the range hood; wherein opening the oil filter mechanism and opening at least one air inlet of the range hood are used to increase the air intake area, and rotating the oil filter mechanism of the range hood is used to bring the air inlet closer to the source of oil fumes.

[0099] The aforementioned oil filter mechanism operation control module is used to control the oil filter mechanism on the left side of the range hood to open or rotate if the target position oil fume concentration is greater than the third oil fume concentration, including the first position oil fume concentration; to control the oil filter mechanism on the right side of the range hood to open or rotate if the target position oil fume concentration is greater than the third oil fume concentration, including the second position oil fume concentration; and to control the oil filter mechanism on the top of the range hood to open or rotate if the target position oil fume concentration is greater than the third oil fume concentration, including the third position oil fume concentration.

[0100] The aforementioned oil filter mechanism operation control module is used to control the oil filter mechanism of the range hood to remain open or rotate if the ratio is less than the second threshold; after the oil filter mechanism of the range hood remains open or rotated for a preset duration, the ratio of the target position oil fume concentration to the third oil fume concentration is re-determined; if the re-determined ratio is less than the second threshold, the oil filter mechanism of the range hood is controlled to close.

[0101] The aforementioned motor operation control module is used to control the operation of the range hood motor without adjusting the operating level if the third oil fume concentration is less than a preset first threshold and the third oil fume concentration is less than or equal to the second oil fume concentration; and to control the operation of the range hood motor based on the ratio of the second oil fume concentration to the third oil fume concentration if the third oil fume concentration is less than the first threshold and the third oil fume concentration is greater than the second oil fume concentration.

[0102] The aforementioned motor operation control module is used to determine the ratio of the second oil fume concentration to the third oil fume concentration; if the ratio is less than a preset third threshold, the operating level of the range hood motor is reduced; if the ratio is greater than or equal to the third threshold, the operating level of the range hood motor is not adjusted.

[0103] See Figure 5 The diagram shows another control device for a range hood. This control device also includes an oil filter mechanism and motor operation control module 44, which is connected to the oil fume concentration acquisition module 41. The oil filter mechanism and motor operation control module 44 is used to control the oil filter mechanism of the range hood to open or rotate to its maximum value if the third oil fume concentration is greater than or equal to a preset first threshold. After the oil filter mechanism of the range hood has been open or rotated to its maximum value for a preset duration, the operation of the oil filter mechanism and motor of the range hood is controlled based on the first threshold, the third oil fume concentration, and the fourth threshold.

[0104] The aforementioned oil filter mechanism and motor operation control module are used to control the oil filter mechanism of the range hood to remain open or rotate to its maximum value if the third oil fume concentration is less than the first threshold and the third oil fume concentration is greater than or equal to the fourth threshold; to increase the operating level of the range hood's motor if the third oil fume concentration is greater than or equal to the first threshold; and to control the oil filter mechanism of the range hood to open or rotate based on the target position oil fume concentration that is greater than the third oil fume concentration among the oil fume concentrations at the first, second, and third positions.
