The following will describe in detail.

Example 1

Referring to fig. 1, fig. 1 is a flow chart of a control method of a range hood according to an embodiment of the present invention. The method described in fig. 1 may be applied to a corresponding control terminal, control device, or control server, and the server may be a local server or a cloud server. Specifically, the fume sucking device to be controlled by the method comprises a fume sucking fan, a first flue and a second flue, wherein the fume sucking fan can be connected with the first flue and the second flue at the same time so as to be used for controlling the wind power of the two flues at the same time, and specifically, the position of a fume sucking opening of the first flue is higher than that of the second flue. Optionally, the smoke absorbing mouth of the first flue may be disposed directly above the working area of the oil fume absorbing device, for example, directly above the gas stove, so as to absorb the oil fume, optionally, the smoke absorbing mouth of the second flue may be disposed at two sides of the working area, and the height of the smoke absorbing mouth of the second flue is less than that of the smoke absorbing mouth of the first flue, so as to absorb the oil fume in the area near the height, thereby realizing more flexible and comprehensive oil fume extracting effect.

As shown in fig. 1, the control method of the oil fume exhaust apparatus may include the following operations:

101. and acquiring the oil smoke concentration parameter obtained by monitoring by the first sensor.

Specifically, the oil smoke concentration parameter is used for indicating the oil smoke concentration in the working area of the oil smoke absorbing equipment. Optionally, the first sensor is a soot concentration sensor, which may be used to detect the concentration of soot. Optionally, the first sensor is one or more sensors, and the combination of the plurality of sensors may improve the accuracy of detection. Alternatively, the first sensor may be arranged in the vicinity of the smoke mouth of the first and/or second smoke duct of the extractor hood device, or may be arranged in the vicinity of the working area of the extractor hood device, i.e. the cooking area, e.g. on the wall of the cooking area. Optionally, the first sensor can also be a plurality of oil smoke sensors that follow oil smoke ascending direction interval arrangement in proper order and set up to be used for measuring the oil smoke concentration in different positions, in order to reach more accurate oil smoke measurement effect.

102. And determining a concentration related control instruction according to the oil smoke concentration parameter and a preset parameter threshold judgment rule.

Specifically, the concentration-related control instruction is used for controlling the smoking amount ratio of the first flue and the second flue and/or the wind speed of the smoking fan.

Alternatively, the control of the ratio of the smoke amounts of the first and second flues may be achieved by a wind deflector being provided in both flues at the same time, for example a concentration-related control command may be sent to the rotatable wind deflector to vary the cross-sectional area of the ventilated path of both flues.

Alternatively, the control of the smoking amount ratio of the first flue and the second flue may be achieved by wind shields respectively disposed in the two flues, for example, a concentration-related control instruction may be sent to the wind shields in the two flues respectively to change the sectional areas of the ventilated paths of the two flues.

Optionally, the control of the ratio of the smoke amounts of the first flue and the second flue can also be controlled by an externally arranged smoke baffle, for example, a smoke baffle which can be used for guiding can be arranged, and when receiving a concentration related control instruction, the smoke baffle can relatively guide the smoke generated by cooking to the smoke inlet of the first flue or the smoke inlet of the second flue so as to change the smoke inlet of the smoke inlets of the two flues. For example, a smoke baffle plate for shielding can be provided, and when the smoke baffle plate receives a concentration related control instruction, part or all of the smoke suction ports of the first flue or the smoke suction ports of the second flue can be relatively shielded, so that the smoke inlet amount of the smoke suction ports of the two flues can be changed.

Therefore, the method described by implementing the embodiment of the invention can flexibly control the smoking amount ratio of different oil fume suction channels based on the oil fume concentration information through the skillfully designed double-channel oil fume suction equipment, thereby realizing more intelligent and more targeted oil fume extraction effect, being beneficial to realizing cleaner cooking environment and reducing the oil fume pollution of a cooking area.

As an optional implementation manner, in the step 102, determining the concentration-related control instruction according to the oil smoke concentration parameter and the preset parameter threshold judgment rule includes:

and when the oil smoke concentration parameter is judged to be smaller than the first concentration threshold value, determining a first concentration related control instruction.

Specifically, the first concentration-related control instruction is used for controlling the smoking amount of the first flue to be smaller than the smoking amount of the second flue. For example, the first concentration related control instruction may be sent to the driving device of the smoke baffle through the smoke baffle for shielding, so as to drive the smoke baffle to relatively shield part or all of the smoking openings of the first flue, so that the smoke inlet of the first flue is smaller than the smoke inlet of the second flue. Or the first concentration related control instruction is sent to the driving device of the smoke baffle plate through the smoke baffle plate for guiding, so that the smoke baffle plate is driven to relatively guide the oil smoke to the smoke suction opening of the second flue more, and the smoke inlet of the first flue is smaller than that of the second flue.

Optionally, the first concentration-related control instruction may also be used to control the wind speed of the smoking fan to reach the first wind speed. Alternatively, the first wind speed should be a smaller wind speed, because the oil smoke concentration is smaller at this time, which is advantageous for saving power sources.

Therefore, when the optional implementation mode is implemented, the smoke amount of the first flue is controlled to be higher than that of the second flue when the smoke concentration parameter is judged to be smaller than the first concentration threshold, so that a more intelligent and more targeted smoke extraction effect can be realized, a cleaner cooking environment is realized, and the smoke pollution of a cooking area is reduced.

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

when the oil smoke concentration parameter is judged to be not smaller than the first concentration threshold, judging whether the oil smoke concentration parameter is larger than the first concentration threshold and smaller than a second concentration threshold, wherein the second concentration threshold is larger than the first concentration threshold;

And when the oil smoke concentration parameter is judged to be larger than the first concentration threshold value and smaller than the second concentration threshold value, determining a second concentration related control instruction.

Specifically, the second concentration-related control instruction is used for controlling the smoking amount of the first flue to be equal to the smoking amount of the second flue. For example, the second concentration related control instruction may be sent to the driving device of the smoke baffle through the above smoke baffle for shielding, so as to drive the smoke baffle not to shield the smoke mouths of the two flues, so that the smoke inlet amount of the first flue is equal to the smoke inlet amount of the second flue. Or the second concentration related control instruction is sent to the driving device of the smoke baffle plate through the smoke baffle plate for guiding, so that the smoke baffle plate is driven to guide the oil smoke to the smoke suction openings of the two flues relatively and uniformly, and the smoke inlet amount of the first flue is equal to the smoke inlet amount of the second flue.

Optionally, the second concentration-related control command may 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.

And when the oil smoke concentration parameter is judged to be larger than the second concentration threshold value, determining a third concentration related control instruction.

Specifically, the third concentration-related control instruction is used for controlling the smoking amount of the first flue to be larger than the smoking amount of the second flue. For example, the third concentration related control instruction may be sent to the driving device of the smoke baffle through the smoke baffle for shielding, so as to drive the smoke baffle to relatively shield part or all of the smoking openings of the second flue, so that the smoke inlet of the first flue is larger than the smoke inlet of the second flue. Or the first concentration related control instruction is sent to the driving device of the smoke baffle plate through the smoke baffle plate for guiding, so that the smoke baffle plate is driven to relatively guide the oil smoke to the smoke suction opening of the first flue more, and the smoke inlet of the first flue is larger than the smoke inlet of the second flue.

Optionally, the third concentration-related control command may 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.

Therefore, by judging the relation between the oil smoke concentration parameter and the first concentration threshold value and the second concentration threshold value, different control instructions can be respectively generated to control the wind speed of the fan to reach different corresponding wind speeds or control the smoking amount ratio of the first flue and the second flue, so that more intelligent and more targeted oil smoke extraction effect can be realized, cleaner cooking environment can be realized, and the oil smoke pollution of a cooking area can be reduced.

And when the oil smoke concentration parameter is judged to be larger than the dangerous concentration threshold value, determining a fourth concentration related control instruction.

Specifically, the fourth concentration related control instruction is used for controlling the second flue to be closed and the smoking amount of the first flue to be maximum, for example, the fourth concentration related control instruction can be sent to the driving device of the smoke baffle through the above smoke baffle for shielding, so as to drive the smoke baffle to completely shield the smoking opening of the second flue, and the fan power of the first flue is controlled to be maximum, so that the second flue is closed and the smoking amount of the first flue is maximum. Or the fourth concentration related control instruction is sent to the driving device of the smoke baffle plate through the smoke baffle plate for guiding, so that the smoke baffle plate is driven to guide the oil smoke to the smoke suction opening of the first flue completely, and the second flue is closed and the smoke suction amount of the first flue is maximized.

Optionally, the fourth concentration-related control instruction may also be used to control the wind speed of the smoking fan to reach a maximum wind speed.

Alternatively, the hazard concentration threshold may be greater than the aforementioned third concentration threshold.

Therefore, when the oil smoke concentration parameter is judged to be larger than the dangerous concentration threshold, the second flue is controlled to be closed, the smoking amount of the first flue is controlled to be maximum, and accordingly the intelligent and targeted oil smoke extraction effect can be achieved, the clean cooking environment can be achieved, and the oil smoke pollution of the cooking area is reduced.

As an alternative embodiment, the method further comprises:

And acquiring the oil smoke flow rate parameter obtained by monitoring by the second sensor.

Specifically, the fume flow rate parameter is used for indicating the fume rising speed in the working area of the fume suction equipment. Optionally, the second sensor and the first sensor may be separate sensors or may be sensors that are integrally provided, for example, the second sensor may be a plurality of oil smoke sensors that are sequentially arranged at intervals along an oil smoke rising direction, so that a rising speed of oil smoke can be obtained through calculation by detecting time of oil smoke at different positions.

And determining a flow rate related control instruction according to the oil smoke flow rate parameter and a preset flow rate threshold judgment rule.

Specifically, the flow rate related control instruction is used for controlling the smoking amount ratio of the first flue and the second flue and/or the wind speed of the smoking fan.

Alternatively, the control of the ratio of the smoke amounts of the first and second flues may be achieved by a wind deflector being provided in both flues at the same time, for example a flow rate related control command may be sent to the rotatable wind deflector to vary the cross-sectional area of the ventilated path of both flues.

Alternatively, the control of the smoking amount ratio of the first flue and the second flue may be achieved by wind shields respectively disposed in the two flues, for example, a flow velocity related control instruction may be sent to the wind shields in the two flues respectively to change the sectional areas of the ventilated paths of the two flues.

Optionally, the control of the ratio of the smoke amounts of the first flue and the second flue can also be controlled by an externally arranged smoke baffle, for example, a smoke baffle which can be used for guiding can be arranged, and when receiving a control instruction related to the flow rate, the smoke baffle can relatively guide the smoke generated by cooking to the smoke inlet of the first flue or the smoke inlet of the second flue so as to change the smoke inlet amount of the smoke inlets of the two flues. For example, a smoke baffle plate for shielding can be provided, and when receiving a control instruction related to the flow rate, the smoke baffle plate can relatively shield part or all of the smoke suction openings of the first flue or the smoke suction openings of the second flue so as to change the smoke inlet amount of the smoke suction openings of the two flues.

Therefore, by implementing the optional implementation mode, the smoking amount ratio of different oil smoke suction channels can be flexibly controlled based on the oil smoke flow rate information, so that the intelligent and targeted oil smoke extraction effect can be realized, the clean cooking environment can be realized, and the oil smoke pollution of a cooking area can be reduced.

As an optional implementation manner, in the step, determining the flow rate related control instruction according to the oil smoke flow rate parameter and a preset flow rate threshold judgment rule includes:

Judging whether the oil smoke flow rate parameter is smaller than a first flow rate threshold value or not;

And when the oil smoke flow rate parameter is judged to be smaller than the first flow rate threshold value, determining a first flow rate related control instruction.

Specifically, the first flow rate related control instruction is used for controlling the smoking amount of the first flue to be smaller than the smoking amount of the second flue, for example, the first flow rate related control instruction can be sent to the driving device of the smoke baffle through the smoke baffle for shielding, so that the smoke baffle is driven to relatively shield part or all of the smoking openings of the first flue, the smoking amount of the first flue is smaller than the smoking amount of the second flue, and therefore the effect that the low-flow-rate oil smoke can be absorbed by the second flue more. Or through the above-mentioned cigarette baffle that is used for the direction, send the relevant controlling instruction of first flow rate to the drive arrangement of this cigarette baffle to drive this cigarette baffle and guide the cigarette smoke more to the smoking mouth of second flue, so that the smoking volume of first flue is less than the smoking volume of second flue, in order to realize that the cigarette smoke that the flow rate is slow can be absorbed more by the lower second flue of position.

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

and when the oil smoke flow velocity parameter is judged to be larger than the first flow velocity threshold value, determining a second flow velocity related control instruction.

Specifically, the second flow rate related control instruction is used for controlling the smoking amount of the first flue to be larger than that of the second flue, for example, the second flow rate related control instruction can be sent to the driving device of the smoke baffle through the above smoke baffle for shielding, so as to drive the smoke baffle to relatively shield part or all of the smoking openings of the second flue, so that the smoking amount of the first flue is larger than that of the second flue, and the purpose that the smoke with high flow rate can be absorbed by the first flue with higher position is achieved. Or through the above-mentioned cigarette baffle that is used for the direction, send the relevant controlling instruction of second flow rate to the drive arrangement of this cigarette baffle to drive this cigarette baffle and guide the smoking mouth of first flue more with the oil smoke, so that the smoking volume of first flue is greater than the smoking volume of second flue, in order to realize that the oil smoke that the velocity of flow is fast can be absorbed more by the higher first flue of position.

Optionally, the second flow rate related control command may also be used to control the wind speed of the smoking fan to reach a fifth wind speed, where the fifth wind speed is greater than the fourth wind speed.

Therefore, by judging the relation between the oil smoke flow rate parameter and the first flow rate threshold value, different control instructions can be respectively generated to control the wind speed of the fan to reach different corresponding wind speeds, or control the smoking amount ratio of the first flue and the second flue, so that more intelligent and more targeted oil smoke extraction effect can be realized, cleaner cooking environment is facilitated, and the oil smoke pollution of a cooking area is reduced.

As an alternative embodiment, the fume extractor is also connected to a heating device, which may alternatively be an electromagnetic oven, a gas cooker or a closed heating device such as a microwave oven or an oven. Correspondingly, the method further comprises the steps of:

Environmental parameters monitored by the third sensor are acquired.

In particular, the environmental parameter is used to indicate an environmental parameter within the operating area of the fume extractor, which may optionally include an ambient temperature and/or an ambient carbon monoxide concentration. Accordingly, the third sensor may include one or both of a temperature sensor and a carbon monoxide sensor. Alternatively, the third sensor and the first sensor or the second sensor may be separately provided sensors or integrally provided sensors. In particular, the third sensor may be arranged on a working area of the heating device, such as a side wall of the kitchen cooking area, for more accurate acquisition of environmental parameters of the working area.

And determining a heating control instruction according to the environmental parameters and a preset environmental threshold judgment rule, wherein the heating control instruction is used for controlling the working parameters of the heating equipment.

Therefore, the implementation of the optional implementation mode can flexibly control the working parameters of the heating equipment based on the environmental parameters, so that a more intelligent and targeted auxiliary cooking effect can be realized, safer cooking environment can be realized, and the heating safety risk of a cooking area is reduced.

As an optional implementation manner, in the step, determining the heating control instruction according to the environmental parameter and the preset environmental threshold judgment rule includes:

judging whether the ambient temperature is greater than a dangerous temperature threshold;

and when the environment temperature is judged to be greater than the dangerous temperature threshold value, determining a first heating control instruction.

Specifically, the first heating control instruction is used for controlling the heating of the heating equipment to stop or reduce below a preset power.

It can be seen that when the environment temperature is judged to be greater than the dangerous temperature threshold, the optional implementation mode can control the heating of the heating equipment to stop or reduce to below the preset power, so that a safer cooking environment can be realized, and the heating safety risk of the cooking area is reduced.

judging whether the concentration of the environmental carbon monoxide is greater than a dangerous carbon monoxide concentration threshold value;

and when the environmental carbon monoxide concentration is judged to be greater than the dangerous carbon monoxide concentration threshold, determining a second heating control instruction.

Specifically, the second heating control instruction is for controlling the heating stop of the heating apparatus.

It can be seen that when the environmental carbon monoxide concentration is determined to be greater than the dangerous carbon monoxide concentration threshold, the optional implementation manner can control the heating device to stop heating, so that a safer cooking environment can be realized, and the heating safety risk of the cooking area is reduced.
