[0064] The present invention discloses a control method, device and system for an oil fume extraction device, which can, through a cleverly designed dual-channel oil fume extraction device, flexibly control the proportion of the oil fume extraction volume of different oil fume extraction channels based on the oil fume concentration information, so as to achieve a more intelligent and targeted oil fume extraction effect, which is beneficial to achieving a cleaner cooking environment and reducing the oil fume pollution in the cooking area. The following will be described in detail respectively.

[0065] Embodiment 1

[0066] Please refer to Figure 1 , Figure 1 which is a schematic flow chart of a control method for an oil fume extraction device disclosed in an embodiment of the present invention. Among them, Figure 1 the described method can be applied to a corresponding control terminal, control device or control server, and the server can be a local server or a cloud server. Specifically, the oil fume extraction device to be controlled by the method includes a smoking fan, a first flue and a second flue. Among them, the smoking fan can be connected to both the first flue and the second flue at the same time to control the wind force of the two flues at the same time. Specifically, the smoking port position of the first flue is higher than the smoking port position of the second flue. Optionally, the smoking port of the first flue can be set directly above the working area of the oil fume extraction device, for example, directly above the gas stove, for oil fume extraction. Optionally, the smoking port of the second flue can be set on both sides of the working area, and the height is less than that of the smoking port of the first flue, for oil fume extraction in the area near this height, so as to achieve a more flexible and comprehensive oil fume extraction effect.

[0067] As Figure 1 shown, the control method of the oil fume extraction device may include the following operations:

[0068] 101. Obtain the oil fume concentration parameter monitored by the first sensor.

[0069] Specifically, the oil fume concentration parameter is used to indicate the oil fume concentration in the working area of the oil fume extraction device. Optionally, the first sensor is an oil fume concentration sensor, which can be used to detect the oil fume concentration. Optionally, the first sensor is one or more sensors, and the combination of multiple sensors can improve the detection accuracy. Optionally, the first sensor can be set near the smoking port of the first flue and / or the second flue of the oil fume extraction device, or can be set in the working area of the oil fume extraction device, that is, near the cooking area, such as on the wall of the cooking area. Optionally, the first sensor can also be multiple oil fume sensors arranged at intervals in sequence along the oil fume rising direction, so as to measure the oil fume concentration at different positions to achieve a more accurate oil fume measurement effect.

[0070] 102. Determine a concentration-related control instruction according to the oil fume concentration parameter and a preset parameter threshold judgment rule.

[0071] Specifically, the concentration-related control instruction is used to control the smoking volume ratio of the first flue and the second flue and / or the wind speed of the smoking fan.

[0072] Optionally, the control of the smoking volume ratio of the first flue and the second flue can be achieved by wind baffle plates simultaneously arranged in the two flues. For example, a concentration-related control instruction can be sent to the rotatable wind baffle plates to change the cross-sectional area of the ventilation paths of the two flues.

[0073] Optionally, the control of the smoking volume ratio of the first flue and the second flue can be achieved by wind baffle plates respectively arranged in the two flues. For example, concentration-related control instructions can be sent to the wind baffle plates in the two flues respectively to change the cross-sectional area of the ventilation paths of the two flues.

[0074] Optionally, the control of the smoking volume ratio of the first flue and the second flue can also be controlled by an externally arranged smoke baffle plate. For example, a guiding smoke baffle plate can be set. When the smoke baffle plate receives a concentration-related control instruction, it can relatively guide the oil fume generated by cooking to the smoking port of the first flue or the smoking port of the second flue to change the smoke intake of the smoking ports of the two flues. For another example, a shielding smoke baffle plate can be set. When the smoke baffle plate receives a concentration-related control instruction, it can relatively shield part or all of the smoking port of the first flue or the smoking port of the second flue to change the smoke intake of the smoking ports of the two flues.

[0075] It can be seen that implementing the method described in the embodiments of the present invention can flexibly control the smoking volume ratio of different oil fume suction channels based on the oil fume concentration information through the ingeniously designed dual-channel oil fume suction device, so as to achieve a more intelligent and targeted oil fume extraction effect, which is beneficial to achieving a cleaner cooking environment and reducing the oil fume pollution in the cooking area.

[0076] As an optional implementation manner, in step 102 above, determining a concentration-related control instruction according to the oil fume concentration parameter and a preset parameter threshold judgment rule includes:

[0077] Judge whether the oil fume concentration parameter is less than the first concentration threshold;

[0078] When it is judged that the oil fume concentration parameter is less than the first concentration threshold, determine the first concentration-related control instruction.

[0079] Specifically, the first concentration-related control instruction is used to control the smoke intake of the first flue to be less than that of the second flue. For example, through the above-mentioned smoke baffle for blocking, the first concentration-related control instruction can be sent to the driving device of the baffle to drive the baffle to relatively block part or all of the smoke intake opening of the first flue, so that the smoke intake of the first flue is less than that of the second flue. Or through the above-mentioned smoke baffle for guiding, the first concentration-related control instruction can be sent to the driving device of the baffle to drive the baffle to relatively direct more oil fume to the smoke intake opening of the second flue, so that the smoke intake of the first flue is less than that of the second flue.

[0080] Optionally, the first concentration-related control instruction can also be used to control the wind speed of the smoke extraction fan to reach the first wind speed. Optionally, the first wind speed should be a relatively low wind speed because the oil fume concentration is relatively low at this time, which is beneficial to saving the power source.

[0081] It can be seen that implementing this optional implementation method can control the smoke intake of the first flue to be higher than that of the second flue when it is determined that the oil fume concentration parameter is less than the first concentration threshold, so as to achieve a more intelligent and targeted oil fume extraction effect, which is beneficial to achieving a cleaner cooking environment and reducing the oil fume pollution in the cooking area.

[0082] As an optional implementation method, in step 102 above, determining the concentration-related control instruction according to the oil fume concentration parameter and the preset parameter threshold judgment rule further includes:

[0083] When it is determined that the oil fume concentration parameter is not less than the first concentration threshold, it is judged whether the oil fume concentration parameter is greater than the first concentration threshold and less than the second concentration threshold; where the second concentration threshold is greater than the first concentration threshold;

[0084] When it is determined that the oil fume concentration parameter is greater than the first concentration threshold and less than the second concentration threshold, the second concentration-related control instruction is determined.

[0085] Specifically, the second concentration-related control instruction is used to control the smoke intake of the first flue to be equal to that of the second flue. For example, through the above-mentioned smoke baffle for blocking, the second concentration-related control instruction can be sent to the driving device of the baffle to drive the baffle not to block the smoke intake openings of the two flues, so that the smoke intake of the first flue is equal to that of the second flue. Or through the above-mentioned smoke baffle for guiding, the second concentration-related control instruction can be sent to the driving device of the baffle to drive the baffle to relatively direct the oil fume evenly to the smoke intake openings of the two flues, so that the smoke intake of the first flue is equal to that of the second flue.

[0086] Optionally, the second concentration-related control instruction can also be used to control the wind speed of the smoking fan to reach a second wind speed, where the second wind speed is greater than the first wind speed.

[0087] When it is determined that the oil fume concentration parameter is greater than the second concentration threshold, a third concentration-related control instruction is determined.

[0088] Specifically, the third concentration-related control instruction is used to control the smoking volume of the first flue to be greater than that of the second flue. For example, through the above-mentioned smoke baffle for blocking, the third concentration-related control instruction can be sent to the driving device of the baffle to drive the baffle to relatively block part or all of the smoking port of the second flue, so that the smoke intake of the first flue is greater than that of the second flue. Or through the above-mentioned smoke baffle for guiding, the first concentration-related control instruction is sent to the driving device of the baffle to drive the baffle to relatively direct more oil fume to the smoking port of the first flue, so that the smoke intake of the first flue is greater than that of the second flue.

[0089] Optionally, the third concentration-related control instruction can also control the wind speed of the smoking fan to reach a third wind speed, where the third wind speed is greater than the second wind speed.

[0090] It can be seen that implementing this optional implementation method can generate different control instructions by judging the relationship between the oil fume concentration parameter and the first concentration threshold and the second concentration threshold, so as to control the wind speed of the fan to reach different corresponding wind speeds, or control the proportion of the smoking volume of the first flue and the second flue, so as to achieve a more intelligent and targeted oil fume extraction effect, which is beneficial to achieving a cleaner cooking environment and reducing the oil fume pollution in the cooking area.

[0091] As an optional implementation method, in step 102 above, determining the concentration-related control instruction according to the oil fume concentration parameter and the preset parameter threshold judgment rule further includes:

[0092] Judging whether the oil fume concentration parameter is greater than the dangerous concentration threshold;

[0093] When it is determined that the oil fume concentration parameter is greater than the dangerous concentration threshold, a fourth concentration-related control instruction is determined.

[0094] Specifically, the fourth concentration-related control instruction is used to control the second flue to close and the smoke extraction volume of the first flue to reach the maximum. For example, through the smoke baffle for blocking mentioned above, the fourth concentration-related control instruction can be sent to the driving device of the baffle to drive the baffle to completely block the smoke inlet of the second flue, and the fan power of the first flue can be controlled to the maximum, so that the second flue is closed and the smoke extraction volume of the first flue reaches the maximum. Or through the smoke baffle for guiding mentioned above, the fourth concentration-related control instruction can be sent to the driving device of the baffle to drive the baffle to direct all the cooking fumes to the smoke inlet of the first flue, so that the second flue is closed and the smoke extraction volume of the first flue reaches the maximum.

[0095] Optionally, the fourth concentration-related control instruction can also be used to control the wind speed of the smoke extraction fan to reach the maximum wind speed.

[0096] Optionally, the dangerous concentration threshold can be greater than the aforementioned third concentration threshold.

[0097] It can be seen that implementing this optional implementation method can control the second flue to close and the smoke extraction volume of the first flue to reach the maximum when it is determined that the cooking fume concentration parameter is greater than the dangerous concentration threshold. Thus, a more intelligent and targeted cooking fume extraction effect can be achieved, which is beneficial to achieving a cleaner cooking environment and reducing the cooking fume pollution in the cooking area.

[0098] As an optional implementation method, the method further includes:

[0099] Obtain the cooking fume flow rate parameter monitored by the second sensor.

[0100] Specifically, the cooking fume flow rate parameter is used to indicate the rising speed of the cooking fumes in the working area of the fume extraction device. Optionally, the second sensor and the first sensor can be separate sensors or integrated sensors. For example, the second sensor can be multiple cooking fume sensors arranged at intervals in sequence along the rising direction of the cooking fumes, so that the rising speed of the cooking fumes can be calculated by the time when the cooking fumes are detected at different positions.

[0101] According to the cooking fume flow rate parameter and the preset flow rate threshold judgment rule, determine the flow rate-related control instruction.

[0102] Specifically, the flow rate-related control instruction is used to control the smoke extraction volume ratio of the first flue and the second flue and / or the wind speed of the smoke extraction fan.

[0103] Optionally, the control of the smoke extraction volume ratio of the first flue and the second flue can be achieved by the wind baffle arranged in both flues at the same time. For example, the flow rate-related control instruction can be sent to the rotatable wind baffle to change the cross-sectional area of the ventilable path of the two flues.

[0104] Optionally, the control of the smoking volume ratio of the first flue and the second flue can be achieved by windshields respectively arranged in the two flues. For example, control instructions related to the flow rate can be respectively sent to the windshields in the two flues to change the cross-sectional area of the ventilable paths of the two flues.

[0105] Optionally, the control of the smoking volume ratio of the first flue and the second flue can also be controlled by a smoke baffle arranged externally. For example, a smoke baffle that can be used for guiding can be set. When this smoke baffle receives a control instruction related to the flow rate, it can relatively direct the cooking fumes to the smoking port of the first flue or the smoking port of the second flue to change the smoke intake volume of the smoking ports of the two flues. Another example is that a smoke baffle for blocking can be set. When this smoke baffle receives a control instruction related to the flow rate, it can relatively block part or all of the smoking port of the first flue or the smoking port of the second flue to change the smoke intake volume of the smoking ports of the two flues.

[0106] It can be seen that implementing this optional implementation method can flexibly control the smoking volume ratio of different oil fume extraction channels based on the oil fume flow rate information, thereby achieving a more intelligent and targeted oil fume extraction effect, which is conducive to achieving a cleaner cooking environment and reducing the oil fume pollution in the cooking area.

[0107] As an optional implementation method, in the above steps, determining the control instruction related to the flow rate according to the oil fume flow rate parameter and the preset flow rate threshold judgment rule includes:

[0108] Judging whether the oil fume flow rate parameter is less than the first flow rate threshold;

[0109] When it is judged that the oil fume flow rate parameter is less than the first flow rate threshold, a first control instruction related to the flow rate is determined.

[0110] Specifically, the first control instruction related to the flow rate is used to control the smoking volume of the first flue to be less than that of the second flue. For example, through the above-mentioned smoke baffle for blocking, the first control instruction related to the flow rate can be sent to the driving device of this smoke baffle to drive this smoke baffle to relatively block part or all of the smoking port of the first flue, so that the smoking volume of the first flue is less than that of the second flue, so as to achieve that the oil fume with a slow flow rate can be more absorbed by the second flue at a lower position. Or through the above-mentioned smoke baffle for guiding, the first control instruction related to the flow rate can be sent to the driving device of this smoke baffle to drive this smoke baffle to direct the oil fume more to the smoking port of the second flue, so that the smoking volume of the first flue is less than that of the second flue, so as to achieve that the oil fume with a slow flow rate can be more absorbed by the second flue at a lower position.

[0111] Optionally, the first control instruction related to the flow rate can also be used to control the wind speed of the smoking fan to reach the fourth wind speed;

[0112] When it is determined that the oil fume flow rate parameter is greater than the first flow rate threshold, a second flow rate-related control instruction is determined.

[0113] Specifically, the second flow rate-related control instruction is used to control the oil fume absorption amount of the first flue to be greater than that of the second flue. For example, through the above-mentioned smoke baffle for blocking, the second flow rate-related control instruction can be sent to the driving device of the smoke baffle to drive the smoke baffle to relatively block part or all of the smoke inlet of the second flue, so that the oil fume absorption amount of the first flue is greater than that of the second flue, so as to achieve that the oil fume with a faster flow rate can be more absorbed by the first flue at a higher position. Or through the above-mentioned smoke baffle for guiding, the second flow rate-related control instruction is sent to the driving device of the smoke baffle to drive the smoke baffle to direct more oil fume to the smoke inlet of the first flue, so that the oil fume absorption amount of the first flue is greater than that of the second flue, so as to achieve that the oil fume with a faster flow rate can be more absorbed by the first flue at a higher position.

[0114] Optionally, the second flow rate-related control instruction can also be used to control the wind speed of the oil fume suction fan to reach the fifth wind speed, where the fifth wind speed is greater than the fourth wind speed.

[0115] It can be seen that implementing this optional implementation method can generate different control instructions by judging the relationship between the oil fume flow rate parameter and the first flow rate threshold, so as to control the wind speed of the fan to reach different corresponding wind speeds, or control the proportion of the oil fume absorption amounts of the first flue and the second flue, so as to achieve a more intelligent and targeted oil fume extraction effect, which is beneficial to achieving a cleaner cooking environment and reducing the oil fume pollution in the cooking area.

[0116] As an optional implementation method, the oil fume suction device is also connected to a heating device. Optionally, the heating device can be an induction cooker, a gas stove, or an enclosed heating device such as a microwave oven or an oven, etc. Correspondingly, the method further includes:

[0117] Obtain the environmental parameters monitored by the third sensor.

[0118] Specifically, the environmental parameters are used to indicate the environmental parameters in the working area of the oil fume suction device. Optionally, the environmental parameters can include the environmental temperature and / or the environmental carbon monoxide concentration. Correspondingly, the third sensor can include one or both of a temperature sensor and a carbon monoxide sensor. Optionally, the third sensor and the first sensor or the second sensor can be sensors set separately or sensors set integrally. Specifically, the third sensor can be set in the working area of the heating device, such as on the side wall of the kitchen cooking area, so as to more accurately obtain the environmental parameters of the working area.

[0119] Determine a heating control instruction according to environmental parameters and a preset environmental threshold judgment rule; the heating control instruction is used to control the operating parameters of a heating device.

[0120] It can be seen that implementing this optional implementation method can flexibly control the operating parameters of the heating device based on environmental parameters, thereby achieving a more intelligent and targeted cooking assistance effect, facilitating the realization of a safer cooking environment, and reducing the heating safety risk in the cooking area.

[0121] As an optional implementation method, in the above steps, determining the heating control instruction according to environmental parameters and a preset environmental threshold judgment rule includes:

[0122] Judge whether the environmental temperature is greater than a dangerous temperature threshold;

[0123] When it is judged that the environmental temperature is greater than the dangerous temperature threshold, determine a first heating control instruction.

[0124] Specifically, the first heating control instruction is used to control the heating of the heating device to stop or reduce to below a preset power.

[0125] It can be seen that implementing this optional implementation method can, when it is judged that the environmental temperature is greater than the dangerous temperature threshold, control the heating of the heating device to stop or reduce to below a preset power, thereby achieving a safer cooking environment and reducing the heating safety risk in the cooking area.

[0126] As an optional implementation method, in the above steps, determining the heating control instruction according to environmental parameters and a preset environmental threshold judgment rule includes:

[0127] Judge whether the environmental carbon monoxide concentration is greater than a dangerous carbon monoxide concentration threshold;

[0128] When it is judged that the environmental carbon monoxide concentration is greater than the dangerous carbon monoxide concentration threshold, determine a second heating control instruction.

[0129] Specifically, the second heating control instruction is used to control the heating of the heating device to stop.

[0130] It can be seen that implementing this optional implementation method can, when it is judged that the environmental carbon monoxide concentration is greater than the dangerous carbon monoxide concentration threshold, control the heating of the heating device to stop, thereby achieving a safer cooking environment and reducing the heating safety risk in the cooking area.

[0131] Embodiment 2

[0132] Please refer to Figure 2 , Figure 2 is a schematic structural diagram of a control device for an oil fume suction device disclosed in an embodiment of the present invention. Among them,Figure 2 The described device can be applied to the corresponding control terminal, control device or control server, and the server can be a local server or a cloud server, which is not limited in the embodiments of the present invention. Specifically, the oil fume extraction device to be controlled by the device includes a smoking fan, a first flue and a second flue. Among them, the smoking fan can be connected to both the first flue and the second flue at the same time to control the wind force of the two flues simultaneously. Specifically, the smoking port of the first flue is higher than the smoking port of the second flue. Optionally, the smoking port of the first flue can be set directly above the working area of the oil fume extraction device, for example, directly above the gas stove, to extract oil fume. Optionally, the smoking port of the second flue can be set on both sides of the working area, and the height is less than that of the smoking port of the first flue, so as to extract the oil fume in the area near this height, so as to achieve a more flexible and more comprehensive oil fume extraction effect.

[0133] As Figure 2 shown, the device may include:

[0134] A first acquisition module 201, configured to acquire the oil fume concentration parameter monitored by the first sensor.

[0135] Specifically, the oil fume concentration parameter is used to indicate the oil fume concentration in the working area of the oil fume extraction device. Optionally, the first sensor is an oil fume concentration sensor, which can be used to detect the concentration of oil fume. Optionally, the first sensor is one or more sensors, and the combination of multiple sensors can improve the detection accuracy. Optionally, the first sensor can be set near the smoking ports of the first flue and / or the second flue of the oil fume extraction device, or can be set in the working area of the oil fume extraction device, that is, near the cooking area, such as on the wall of the cooking area. Optionally, the first sensor can also be a plurality of oil fume sensors arranged at intervals in sequence along the upward direction of the oil fume, so as to measure the oil fume concentration at different positions to achieve a more accurate oil fume measurement effect.

[0136] A first determination module 202, configured to determine a concentration-related control instruction according to the oil fume concentration parameter and a preset parameter threshold determination rule.

[0137] Specifically, the concentration-related control instruction is used to control the smoking volume ratio of the first flue and the second flue and / or the wind speed of the smoking fan.

[0138] Optionally, the control of the smoking volume ratio of the first flue and the second flue can be achieved by the wind baffle plates arranged in the two flues at the same time. For example, a concentration-related control instruction can be sent to the rotatable wind baffle plate to change the cross-sectional area of the ventilation path of the two flues.

[0139] Optionally, the control of the smoking volume ratio of the first flue and the second flue can be achieved by windshields respectively arranged in the two flues. For example, concentration-related control instructions can be respectively sent to the windshields in the two flues to change the cross-sectional area of the ventilation paths available in the two flues.

[0140] Optionally, the control of the smoking volume ratio of the first flue and the second flue can also be controlled by a smoke baffle arranged externally. For example, a smoke baffle that can be used for guiding can be set. When this smoke baffle receives a concentration-related control instruction, it can relatively direct the cooking fumes to the smoking port of the first flue or the smoking port of the second flue to change the smoke intake amount at the smoking ports of the two flues. Another example is that a smoke baffle for blocking can be set. When this smoke baffle receives a concentration-related control instruction, it can relatively block part or all of the smoking port of the first flue or the smoking port of the second flue to change the smoke intake amount at the smoking ports of the two flues.

[0141] It can be seen that implementing the device described in the embodiments of the present invention can, through a cleverly designed dual-channel oil fume extraction device, flexibly control the smoking volume ratio of different oil fume extraction channels based on oil fume concentration information, thereby achieving a more intelligent and targeted oil fume extraction effect, facilitating the realization of a cleaner cooking environment, and reducing the oil fume pollution in the cooking area.

[0142] As an optional implementation manner, the first determination module 202 determines the specific manner of the concentration-related control instruction according to the oil fume concentration parameter and a preset parameter threshold judgment rule, including:

[0143] Judge whether the oil fume concentration parameter is less than the first concentration threshold;

[0144] When it is judged that the oil fume concentration parameter is less than the first concentration threshold, determine the first concentration-related control instruction.

[0145] Specifically, the first concentration-related control instruction is used to control the smoking volume of the first flue to be less than that of the second flue. For example, through the above-mentioned smoke baffle for blocking, the first concentration-related control instruction can be sent to the driving device of this smoke baffle to drive this smoke baffle to relatively block part or all of the smoking port of the first flue, so that the smoke intake amount of the first flue is less than that of the second flue. Or through the above-mentioned smoke baffle for guiding, the first concentration-related control instruction can be sent to the driving device of this smoke baffle to drive this smoke baffle to relatively direct more fumes to the smoking port of the second flue, so that the smoke intake amount of the first flue is less than that of the second flue.

[0146] Optionally, the first concentration-related control instruction can also be used to control the wind speed of the smoking fan to reach the first wind speed. Optionally, the first wind speed should be a relatively small wind speed because the oil fume concentration is small at this time, which is beneficial to saving the power source.

[0147] It can be seen that implementing this optional implementation mode can control the smoke extraction amount of the first flue to be higher than that of the second flue when it is determined that the oil fume concentration parameter is less than the first concentration threshold. Thus, a more intelligent and targeted oil fume extraction effect can be achieved, which is beneficial to achieving a cleaner cooking environment and reducing the oil fume pollution in the cooking area.

[0148] As an optional implementation mode, the specific manner for the first determination module 202 to determine the concentration-related control instruction according to the oil fume concentration parameter and the preset parameter threshold judgment rule further includes:

[0149] When it is determined that the oil fume concentration parameter is not less than the first concentration threshold, it is judged whether the oil fume concentration parameter is greater than the first concentration threshold and less than the second concentration threshold; wherein, the second concentration threshold is greater than the first concentration threshold;

[0150] When it is determined that the oil fume concentration parameter is greater than the first concentration threshold and less than the second concentration threshold, the second concentration-related control instruction is determined.

[0151] Specifically, the second concentration-related control instruction is used to control the smoke extraction amount of the first flue to be equal to that of the second flue. For example, through the above-mentioned smoke baffle for shielding, the second concentration-related control instruction can be sent to the driving device of the smoke baffle to drive the smoke baffle not to shield the smoke inlets of the two flues, so that the smoke inlet amount of the first flue is equal to that of the second flue. Or through the above-mentioned smoke baffle for guiding, the second concentration-related control instruction can be sent to the driving device of the smoke baffle to drive the smoke baffle to relatively guide the oil fume evenly to the smoke inlets of the two flues, so that the smoke inlet amount of the first flue is equal to that of the second flue.

[0152] Optionally, the second concentration-related control instruction can also be used to control the wind speed of the smoke extraction fan to reach the second wind speed, where the second wind speed is greater than the first wind speed.

[0153] When it is determined that the oil fume concentration parameter is greater than the second concentration threshold, the third concentration-related control instruction is determined.

[0154] Specifically, the third concentration-related control instruction is used to control the smoke extraction amount of the first flue to be greater than that of the second flue. For example, through the above-mentioned smoke baffle for shielding, the third concentration-related control instruction can be sent to the driving device of the smoke baffle to drive the smoke baffle to relatively shield part or all of the smoke inlet of the second flue, so that the smoke inlet amount of the first flue is greater than that of the second flue. Or through the above-mentioned smoke baffle for guiding, the first concentration-related control instruction can be sent to the driving device of the smoke baffle to drive the smoke baffle to relatively guide more oil fume to the smoke inlet of the first flue, so that the smoke inlet amount of the first flue is greater than that of the second flue.

[0155] Optionally, the third concentration-related control instruction can also control the wind speed of the smoking fan to reach a third wind speed, where the third wind speed is greater than the second wind speed.

[0156] It can be seen that implementing this optional implementation method can generate different control instructions by judging the relationship between the oil fume concentration parameter and the first concentration threshold and the second concentration threshold, so as to control the wind speed of the fan to reach different corresponding wind speeds, or control the proportion of the smoking volume of the first flue and the second flue, thereby realizing a more intelligent and targeted oil fume extraction effect, which is beneficial to achieving a cleaner cooking environment and reducing the oil fume pollution in the cooking area.

[0157] As an optional implementation method, the specific manner for the first determination module 202 to determine the concentration-related control instruction according to the oil fume concentration parameter and the preset parameter threshold judgment rule further includes:

[0158] Judge whether the oil fume concentration parameter is greater than the dangerous concentration threshold;

[0159] When it is judged that the oil fume concentration parameter is greater than the dangerous concentration threshold, a fourth concentration-related control instruction is determined.

[0160] Specifically, the fourth concentration-related control instruction is used to control the second flue to close and the smoking volume of the first flue to reach the maximum. For example, the fourth concentration-related control instruction can be sent to the driving device of the smoke baffle through the above-mentioned smoke baffle for shielding to drive the smoke baffle to completely shield the smoking port of the second flue, and control the fan power of the first flue to the maximum, so that the second flue closes and the smoking volume of the first flue reaches the maximum. Or through the above-mentioned guiding smoke baffle, the fourth concentration-related control instruction is sent to the driving device of the smoke baffle to drive the smoke baffle to direct all the oil fume to the smoking port of the first flue, so that the second flue closes and the smoking volume of the first flue reaches the maximum.

[0161] Optionally, the fourth concentration-related control instruction can also be used to control the wind speed of the smoking fan to reach the maximum wind speed.

[0162] Optionally, the dangerous concentration threshold can be greater than the aforementioned third concentration threshold.

[0163] It can be seen that implementing this optional implementation method can control the second flue to close and the smoking volume of the first flue to reach the maximum when it is judged that the oil fume concentration parameter is greater than the dangerous concentration threshold, thereby realizing a more intelligent and targeted oil fume extraction effect, which is beneficial to achieving a cleaner cooking environment and reducing the oil fume pollution in the cooking area.

[0164] As an optional implementation method, the device further includes:

[0165] A second acquisition module, configured to acquire the oil fume flow rate parameter monitored by a second sensor.

[0166] Specifically, the oil fume flow rate parameter is used to indicate the rising speed of the oil fume in the working area of the oil fume extraction device. Optionally, the second sensor and the first sensor can be separate sensors or integrated sensors. For example, the second sensor can be multiple oil fume sensors arranged at intervals in sequence along the rising direction of the oil fume, so that the rising speed of the oil fume can be calculated by the time when the oil fume is detected at different positions.

[0167] A second determination module, configured to determine a flow rate-related control instruction according to the oil fume flow rate parameter and a preset flow rate threshold determination rule.

[0168] Specifically, the flow rate-related control instruction is used to control the smoking volume ratio of the first flue and the second flue and / or the wind speed of the smoking fan.

[0169] Optionally, the control of the smoking volume ratio of the first flue and the second flue can be realized by the baffle plates arranged in the two flues at the same time. For example, a flow rate-related control instruction can be sent to the rotatable baffle plate to change the cross-sectional area of the ventilable path of the two flues.

[0170] Optionally, the control of the smoking volume ratio of the first flue and the second flue can be realized by the baffle plates respectively arranged in the two flues. For example, flow rate-related control instructions can be sent to the baffle plates in the two flues respectively to change the cross-sectional area of the ventilable paths of the two flues.

[0171] Optionally, the control of the smoking volume ratio of the first flue and the second flue can also be controlled by an externally arranged smoke baffle. For example, a guiding smoke baffle can be set, and when the flow rate-related control instruction is received, the smoke baffle can relatively guide the oil fume generated by cooking to the smoking port of the first flue or the smoking port of the second flue to change the smoke intake of the smoking ports of the two flues. Another example is that a shielding smoke baffle can be set, and when the flow rate-related control instruction is received, the smoke baffle can relatively shield part or all of the smoking port of the first flue or the smoking port of the second flue to change the smoke intake of the smoking ports of the two flues.

[0172] It can be seen that implementing this optional implementation manner can flexibly control the smoking volume ratio of different oil fume extraction channels based on the oil fume flow rate information, so that a more intelligent and targeted oil fume extraction effect can be achieved, which is beneficial to achieving a cleaner cooking environment and reducing the oil fume pollution in the cooking area.

[0173] As an alternative implementation, the specific manner in which the second determination module determines the flow rate-related control instruction according to the oil fume flow rate parameter and the preset flow rate threshold judgment rule includes:

[0174] Judge whether the oil fume flow rate parameter is less than the first flow rate threshold;

[0175] When it is judged that the oil fume flow rate parameter is less than the first flow rate threshold, determine the first flow rate-related control instruction.

[0176] Specifically, the first flow rate-related control instruction is used to control the smoke absorption amount of the first flue to be less than that of the second flue. For example, through the above-mentioned smoke baffle for blocking, the first flow rate-related control instruction can be sent to the driving device of the smoke baffle to drive the smoke baffle to relatively block part or all of the smoke inlet of the first flue, so that the smoke absorption amount of the first flue is less than that of the second flue, so as to ensure that the oil fume with a slow flow rate can be more absorbed by the second flue at a lower position. Or through the above-mentioned smoke baffle for guiding, the first flow rate-related control instruction is sent to the driving device of the smoke baffle to drive the smoke baffle to direct more oil fume to the smoke inlet of the second flue, so that the smoke absorption amount of the first flue is less than that of the second flue, so as to ensure that the oil fume with a slow flow rate can be more absorbed by the second flue at a lower position.

[0177] Optionally, the first flow rate-related control instruction can also be used to control the wind speed of the smoke suction fan to reach the fourth wind speed;

[0178] When it is judged that the oil fume flow rate parameter is greater than the first flow rate threshold, determine the second flow rate-related control instruction.

[0179] Specifically, the second flow rate-related control instruction is used to control the smoke absorption amount of the first flue to be greater than that of the second flue. For example, through the above-mentioned smoke baffle for blocking, the second flow rate-related control instruction can be sent to the driving device of the smoke baffle to drive the smoke baffle to relatively block part or all of the smoke inlet of the second flue, so that the smoke absorption amount of the first flue is greater than that of the second flue, so as to ensure that the oil fume with a fast flow rate can be more absorbed by the first flue at a higher position. Or through the above-mentioned smoke baffle for guiding, the second flow rate-related control instruction is sent to the driving device of the smoke baffle to drive the smoke baffle to direct more oil fume to the smoke inlet of the first flue, so that the smoke absorption amount of the first flue is greater than that of the second flue, so as to ensure that the oil fume with a fast flow rate can be more absorbed by the first flue at a higher position.

[0180] Optionally, the second flow rate-related control instruction can also be used to control the wind speed of the smoke suction fan to reach the fifth wind speed, where the fifth wind speed is greater than the fourth wind speed.

[0181] It can be seen that implementing this optional implementation method can generate different control instructions by judging the relationship between the oil fume flow rate parameter and the first flow rate threshold, so as to control the wind speed of the fan to reach different corresponding wind speeds, or control the proportion of the oil fume absorption amount of the first flue and the second flue, thereby realizing a more intelligent and targeted oil fume extraction effect, which is beneficial to achieving a cleaner cooking environment and reducing the oil fume pollution in the cooking area.

[0182] As an optional implementation method, the oil fume suction device is also connected to a heating device. Optionally, the heating device can be an induction cooker, a gas stove, or an enclosed heating device such as a microwave oven or an oven, etc. Correspondingly, the device further includes:

[0183] A third acquisition module, configured to acquire the environmental parameters monitored by a third sensor.

[0184] Specifically, the environmental parameters are used to indicate the environmental parameters in the working area of the oil fume suction device. Optionally, the environmental parameters may include the environmental temperature and / or the environmental carbon monoxide concentration. Correspondingly, the third sensor may include one or both of a temperature sensor and a carbon monoxide sensor. Optionally, the third sensor and the first sensor or the second sensor may be sensors set separately or sensors set integrally. Specifically, the third sensor may be set in the working area of the heating device, such as on the side wall of the kitchen cooking area, so as to more accurately acquire the environmental parameters of the working area.

[0185] A third determination module, configured to determine a heating control instruction according to the environmental parameters and a preset environmental threshold judgment rule; the heating control instruction is used to control the working parameters of the heating device.

[0186] It can be seen that implementing this optional implementation method can flexibly control the working parameters of the heating device based on the environmental parameters, thereby realizing a more intelligent and targeted cooking assistance effect, which is beneficial to achieving a safer cooking environment and reducing the heating safety risk in the cooking area.

[0187] As an optional implementation method, the specific manner in which the third determination module determines the heating control instruction according to the environmental parameters and a preset environmental threshold judgment rule includes:

[0188] Judge whether the environmental temperature is greater than the dangerous temperature threshold;

[0189] When it is judged that the environmental temperature is greater than the dangerous temperature threshold, determine the first heating control instruction.

[0190] Specifically, the first heating control instruction is used to control the heating of the heating device to stop or reduce to below the preset power.

[0191] It can be seen that implementing this optional implementation can control the heating of the heating device to stop or reduce it to below the preset power when it is determined that the ambient temperature is greater than the dangerous temperature threshold, thereby achieving a safer cooking environment and reducing the heating safety risk in the cooking area.

[0192] As an optional implementation, the third determination module determines the specific manner of the heating control instruction according to the environmental parameters and the preset environmental threshold judgment rule, including:

[0193] Judge whether the ambient carbon monoxide concentration is greater than the dangerous carbon monoxide concentration threshold;

[0194] When it is determined that the ambient carbon monoxide concentration is greater than the dangerous carbon monoxide concentration threshold, determine the second heating control instruction.

[0195] Specifically, the second heating control instruction is used to control the heating of the heating device to stop.

[0196] It can be seen that implementing this optional implementation can control the heating of the heating device to stop when it is determined that the ambient carbon monoxide concentration is greater than the dangerous carbon monoxide concentration threshold, thereby achieving a safer cooking environment and reducing the heating safety risk in the cooking area.
