[0002] At present, air conditioners and range hoods are becoming the mainstream household appliances.

This scheme can dynamically and adaptively adjust the working state of the air conditioner based on the gas displacement of the range hood when both the range hood and the air conditioner are working; since the gas discharged by the air conditioner and the gas discharged by the range hood share the exhaust passage and induced draft fan, the gas displacement has an upper limit, so it is necessary to The displacement is distributed among the range hoods; considering that oil fume emission is a rigid demand, the displacement allocated to the range hood cannot be reduced arbitrarily, so the working state of the air conditioner is adjusted based on the gas displacement of the range hood, which can prevent the exhaust gas from affecting the draft state of the range hood when the air conditioner is working, and avoid the situation where the oil fume cannot be fully discharged to the outside; and since the working state of the air conditioner is adjusted accordingly, it can also avoid the situation where the gas emission of the range hood affects the heat exchange of the air conditioner and thus causes the air conditioning effect to decrease; it can be seen that the solution of this embodiment can ensure the working effect of the air conditioner on the basis of ensuring the normal operation of the range hood.

[0055] In the embodiments of the present application, the case where the air conditioner operates in the cooling mode is taken as an example for explanation; when the embodiments of the present application are actually applied, the air conditioner is not limited to operating in the cooling mode; the implementation details when operating in other modes are similar to those when operating in the cooling mode, and will not be repeated in this application.

[0056] Example 1

[0057] This embodiment provides a household appliance control method, the household appliances may include: a range hood and an air conditioner; the range hood and the air conditioner share an exhaust passage and a common induced draft fan, the household appliance control method of this embodiment is as follows Figure 1 As shown, steps S110-S120 are included:

[0058] S110, after detecting that the range hood and the air conditioner are started, detecting the gas discharge volume of the range hood;

[0059] S120: Adjust the working state of the air conditioner according to the detected gas displacement.

[0060] In this embodiment, the range hood and the air conditioner can share one or a group of exhaust ducts and one or a group of induced draft fans; sharing means that when the air conditioner and the range hood are both working, the gases exhausted by the two will be mixed together and discharged from the exhaust duct. The gas that can be discharged by the exhaust duct in conjunction with the induced draft fan comes partly from the air conditioner and the other part from the range hood.

[0061] In this embodiment, when both the range hood and the air conditioner are working, the working state of the air conditioner will be dynamically and adaptively adjusted based on the gas displacement of the range hood; since the gas discharged by the air conditioner when working and the gas discharged by the range hood share the exhaust channel and the induced draft fan, the gas displacement has an upper limit, and therefore it is necessary to distribute the displacement between the air conditioner and the range hood; considering that oil fume emission is a rigid demand, the displacement allocated to the range hood cannot be arbitrarily reduced, and therefore the working state of the air conditioner is adjusted based on the gas displacement of the range hood, which can prevent the exhaust gas from the air conditioner when working from affecting the induced draft state of the range hood, and avoid the situation where the oil fume cannot be fully discharged outdoors; and since the working state of the air conditioner is adjusted accordingly, it can also avoid the situation where the gas emission of the range hood affects the heat exchange of the air conditioner and thus causes the air conditioning effect to decline; it can be seen that the scheme of this embodiment can ensure the working effect of the air conditioner on the basis of ensuring the normal operation of the range hood.

[0062] In one implementation of this embodiment, after the range hood and the air conditioner are both started, the current gas displacement of the range hood can be continuously detected at certain time intervals, and the working state of the air conditioner can be continuously adjusted according to the latest detected gas displacement; in this way, the air conditioner can be adjusted accordingly according to the working condition of the range hood in real time, thereby ensuring that the working state of the air conditioner can change in time with the working condition of the range hood; by shortening the time interval between the two detections, the real-time performance of the detected gas displacement of the range hood can be improved, thereby enabling the working state of the air conditioner to be adjusted more timely.

[0063] In one implementation of this embodiment, adjusting the working state of the air conditioner according to the gas displacement includes:

[0064] It is determined that the gas displacement of the range hood is reduced, the heat exchange of the air conditioner is increased, and the power of the system compressor of the air conditioner is reduced to achieve energy saving.

[0065] In this embodiment, when the gas displacement of the range hood is reduced, more gas displacement in the exhaust channel can be provided to the air conditioner; and the increase in the available displacement of the air conditioner means that the heat exchange capacity of the air conditioner can be increased; after the heat exchange capacity of the air conditioner is increased, even if the compressor power is appropriately reduced, the original cooling effect of the air conditioner can be maintained unchanged, and energy can be saved. Therefore, in response to the reduction in the gas displacement of the range hood, this embodiment increases the heat exchange capacity of the air conditioner and reduces the compressor power.

[0066] In an example of this embodiment, when the user enters the stewing stage of cooking or changes to cooking dishes with less oil smoke, the air volume of the range hood will be lowered, so that the gas displacement of the range hood will be reduced, and the heat exchange capacity of the air conditioner can be increased accordingly; after the heat exchange capacity is increased, the cold air delivered to the room will increase. At this time, reducing the power of the air conditioner compressor can still maintain the original cooling effect, but can be more energy-efficient.

[0067] In an optional solution of this embodiment, the heat exchange capacity of the air conditioner can be increased according to a first preset rule, and the compressor power can be reduced accordingly based on the desired cooling effect and the increased heat exchange capacity. For example, the first preset rule can be to increase the heat exchange capacity according to a first correspondence relationship, where the first correspondence relationship can be the increase in heat exchange capacity corresponding to different reductions in the range hood gas displacement. In this way, the amount of heat exchange capacity increase required can be determined based on the detected reduction in the range hood gas displacement. Alternatively, the first correspondence relationship can be the heat exchange capacity of the air conditioner corresponding to different range hood gas displacements, where the lower the gas displacement, the higher the corresponding heat exchange capacity. In this way, after detecting a reduction in the range hood gas displacement, the corresponding heat exchange capacity can be determined based on the reduced gas displacement, and this heat exchange capacity is used as the target heat exchange capacity to increase the heat exchange capacity of the air conditioner. For another example, the first preset rule can be a calculation formula, and the target heat exchange capacity can be calculated using this calculation formula and the current range hood gas displacement. This embodiment can also use other methods to increase the heat exchange capacity and reduce compressor power, and is not limited to the approach of this optional solution.

[0068] This embodiment can operate the air conditioner in a more energy-saving manner and maintain the cooling effect of the air conditioner when the demand for oil fume emission is reduced.

[0069] In one implementation of this embodiment, adjusting the working state of the air conditioner according to the gas displacement includes:

[0070] It is determined that the gas displacement of the range hood is increased, the heat exchange of the air conditioner is reduced, and the power of the system compressor of the air conditioner is increased to maintain the cooling effect.

[0071] In this embodiment, when the gas displacement of the range hood increases, in order to ensure that the oil smoke can be fully discharged, the gas displacement provided to the air conditioner by the exhaust channel needs to be reduced; and the available displacement of the air conditioner is reduced, which means that the heat exchange capacity of the air conditioner needs to be reduced; after the heat exchange capacity of the air conditioner is reduced, if the original cooling effect is to be maintained, the power of the compressor needs to be increased. Therefore, this embodiment responds to the increase in the gas displacement of the range hood, reduces the heat exchange capacity of the air conditioner and increases the power of the compressor.

[0072] In an example of this embodiment, when the user starts cooking dishes with a lot of oil smoke or uses frying, stir-frying, deep-frying, etc. to cook, the air volume of the range hood will be increased, so that the gas displacement of the range hood will increase, which can correspondingly reduce the heat exchange of the air conditioner; after reducing the heat exchange, the cold air delivered to the room will become less. At this time, in order to maintain the original cooling effect, the power of the air conditioner compressor needs to be increased.

[0073] In an optional solution of this embodiment, the air conditioner's heat exchange rate can be reduced according to a second preset rule, and the compressor power can be increased accordingly based on the desired cooling effect and the reduced heat exchange rate. For example, the second preset rule can be to reduce the heat exchange rate according to a second correspondence relationship, where the second correspondence relationship can be the degree of heat exchange reduction corresponding to different increases in the range hood's gas displacement. In this way, the amount of heat exchange reduction required for the air conditioner can be determined based on the detected increase in the range hood's gas displacement. Alternatively, the second correspondence relationship can be the air conditioner's heat exchange rate corresponding to different range hood gas displacements, with higher gas displacements corresponding to lower heat exchange rates. In this way, after detecting an increase in the range hood's gas displacement, the corresponding heat exchange rate is determined based on the increased gas displacement, and this heat exchange rate is used as the target heat exchange rate to reduce the air conditioner's heat exchange rate. For another example, the second preset rule can be a calculation formula, and the target heat exchange rate can be calculated using this calculation formula and the range hood's current gas displacement. This embodiment can use other methods to reduce the heat exchange rate and increase the compressor power, and is not limited to the approach of this optional solution.

[0074] This embodiment can not only ensure that the normal emission of oil smoke is not affected when the demand for oil smoke emission increases, but also ensure that the cooling effect of the air conditioner is not affected by adjusting the working state of the air conditioner.

[0075] In an alternative to the present embodiment, when it is detected that the gas displacement of the range hood has increased, it is possible to first determine whether the sum of the current gas displacements of the range hood and the air conditioner has reached the upper limit of the exhaust duct displacement. If not, the working state of the air conditioner can be adjusted first; if it has reached, the heat exchange capacity of the air conditioner can be reduced accordingly, and the power of the compressor can be increased.

[0076] In one implementation of this embodiment, the control method further includes:

[0077] When adjusting the heat exchange amount of the air conditioner, the total gas discharge volume of the exhaust channel is kept unchanged;

[0078] And / or, when adjusting the heat exchange amount of the air conditioner, the total gas displacement of the exhaust channel is maintained to be less than or equal to a preset total gas displacement threshold.

[0079] In one optional solution of this embodiment, maintaining a constant total gas displacement refers to maintaining the sum of the air conditioning and range hood gas displacements. This total gas displacement can be set equal to or slightly less than the upper displacement limit of the exhaust duct. To maintain a constant total gas displacement, when the range hood gas displacement increases, the air conditioning heat exchange capacity needs to be reduced accordingly. This is equivalent to reducing the air conditioning gas displacement, thus maintaining the sum of the air conditioning and range hood gas displacements constant. Correspondingly, when the range hood gas displacement decreases, the air conditioning heat exchange capacity can be increased to maintain a constant total gas displacement.

[0080] In an alternative to this optional scheme, the total gas displacement can be kept unchanged only when the gas displacement of the range hood increases; if the gas displacement of the range hood decreases, the current working status of the air conditioner is judged. If it is determined that the heat exchange capacity of the air conditioner can meet the user's needs, or the power of the compressor has reached the lower limit, the heat exchange capacity of the air conditioner can no longer be increased, that is, the total gas displacement can be reduced as the gas displacement of the range hood decreases; if the heat exchange capacity of the air conditioner needs to be increased, or the power of the compressor can be reduced, the heat exchange capacity of the air conditioner can be increased accordingly and the power of the compressor can be reduced.

[0081] In another alternative embodiment of this embodiment, a total gas displacement threshold may be pre-set. This threshold may be, but is not limited to, the upper limit of the exhaust duct displacement. This threshold may be calculated based on the cross-sectional dimensions of the exhaust duct, the air volume of the induced draft fan, and other factors, or may be derived through empirical analysis, testing, or other methods. When the range hood's gas displacement increases, if the sum of the air conditioner's and the range hood's gas displacements has not yet reached this total gas displacement threshold, the air conditioner's operating state may be temporarily suspended. Once the total gas displacement threshold is reached, the sum of the gas displacements cannot increase further, so the air conditioner's operating state must be adjusted to ensure the range hood's fume discharge.

[0082] In one implementation of this embodiment, the control method further includes:

[0083] Determining that the gas discharge volume of the range hood is reduced, and reducing the total gas discharge volume of the exhaust passage;

[0084] Determine that the gas discharge volume of the range hood increases, and increase the total gas discharge volume of the exhaust channel.

[0085] In this embodiment, when the range hood's gas displacement changes, in addition to adjusting the air conditioner's operating state, the total gas displacement can also be adjusted. When the range hood's gas displacement increases, the total gas displacement is increased, leaving more available displacement for the air conditioner. This can, to a certain extent, reduce the amount of compressor power required to maintain cooling efficiency, further saving energy. When the range hood's gas displacement decreases, the total gas displacement also decreases, saving the electricity consumed to drain the gas from the exhaust duct.

[0086] In this embodiment, the total gas displacement of the increased exhaust channel can be set to be less than or equal to a preset total gas displacement threshold; that is, the total gas displacement cannot be increased indefinitely, and once the total gas displacement increases to a value equal to the total gas displacement threshold, it cannot continue to increase; in this case, if the gas displacement of the range hood is increased, the heat exchange capacity of the air conditioner can only be reduced and the compressor power can be increased to ensure that the range hood operates normally and maintains the cooling effect.

[0087] In this embodiment, reducing the total gas discharge volume of the exhaust passage may include: reducing the rotation speed of a preset induced draft fan in the exhaust passage;

[0088] Increasing the total gas discharge volume of the exhaust passage may include increasing a rotation speed of a preset induced draft fan in the exhaust passage.

[0089] This embodiment can adjust the working state of the air conditioner according to the working condition of the range hood, which can fully meet the demand for oil fume discharge, ensure the normal operation of the range hood, and also ensure the cooling effect of the air conditioner.

[0090] Example 2

[0091] This embodiment provides a household appliance control method. Based on the first embodiment, in this embodiment, adjusting the working state of the air conditioner according to the detected gas displacement includes:

[0092] According to the detected gas displacement, the heat exchange amount of the air conditioner is adjusted through the valve.

[0093] In this embodiment, after adjusting the heat exchange rate of the air conditioner, the power of the air conditioner compressor can be adjusted accordingly; after increasing the heat exchange rate, the power of the compressor can be reduced to save energy, and after reducing the heat exchange rate, the power of the compressor needs to be increased to maintain the cooling effect.

[0094] In one implementation of this embodiment, the valve may include a first air valve arranged in a first air duct for connecting the air conditioner and the exhaust channel. By adjusting the opening and closing degree of the first air valve, the ventilation volume of the air conditioner in the first air duct can be adjusted, that is, the gas displacement of the air conditioner can be adjusted, thereby adjusting the heat exchange amount of the air conditioner.

[0095] In this embodiment, when the opening and closing degree of the first air valve becomes larger, that is, the degree of opening increases, the ventilation volume of the first air duct increases; when the opening and closing degree of the first air valve becomes smaller, that is, the degree of opening decreases, the ventilation volume of the first air duct decreases; when the opening and closing degree is the smallest, that is, the first air valve is completely closed, the ventilation volume of the first air duct is reduced to 0.

[0096] In this embodiment, the opening and closing degree of the first air valve can be adjusted according to a third preset rule. For example, the first air valve can be adjusted based on the corresponding relationship between heat exchange and opening and closing degree. Once the target heat exchange is determined, the opening and closing degree of the first air valve can be determined. Alternatively, the opening and closing degree can be adjusted gradually until the heat exchange meets the adjustment target. For example, when the heat exchange needs to be increased, the opening degree of the first air valve can be gradually increased until the target ventilation volume is reached; when the ventilation volume needs to be reduced, the opening degree of the first air valve can be gradually reduced until the target ventilation volume is reached.

[0097] In this embodiment, in addition to the first air valve, a second air valve can be provided in the second air duct for connecting the range hood and the exhaust duct. The two air valves can cooperate with each other to jointly control the gas discharge volume entering the exhaust duct.

[0098] In an optional solution of this embodiment, the control method further includes:

[0099] When only the air conditioner is started, the first air valve in the first air duct connected between the air conditioner and the exhaust duct is opened, and the second air valve in the second air duct between the range hood and the exhaust duct is closed; that is, the air conditioner uses the exhaust duct alone.

[0100] In an optional solution of this embodiment, the control method further includes:

[0101] When only the range hood is started, the second air valve in the second air duct between the range hood and the exhaust duct is opened, and the first air valve in the first air duct connected to the air conditioner and the exhaust duct is closed; that is, the range hood uses the exhaust duct alone.

[0102] An example of this embodiment is as follows Figure 2 As shown, exhaust channel B contains a chamber connected to first duct D-1 and second duct D-2, as well as an exhaust duct connected to the chamber. Hot air from air conditioner A-1 is transported to exhaust channel B via first duct D-1, and cooking fumes from range hood A-2 are transported to exhaust channel B via second duct D-2. Both hot air and cooking fumes are exhausted outdoors through exhaust channel B. An induced draft fan C is installed near the chamber of the exhaust duct to direct the gases in the exhaust channel, including hot air from first duct D-1 and cooking fumes from second duct D-2, outdoors.

[0103] In this example, the air duct for outputting cold air from the air conditioner A-1 leads into the room, and the cold air generated by the air conditioner A-1 can be delivered to the user.

[0104] In this example, the induced draft fan C may be an axial flow fan, a centrifugal fan, a mixed flow fan, or the like.

[0105] In this example, a first air valve E-1 and a second air valve E-2 are installed within the first air duct D-1 and the second air duct D-2, respectively. First air valve E-1 controls the airflow within first air duct D-1. This airflow, or the volume of air discharged when air conditioner A-1 is operating, is positively correlated with the heat exchange capacity of air conditioner A-1. Adjusting the opening and closing of first air valve E-1 can adjust the heat exchange capacity of air conditioner A-1. The opening and closing of first air valve E-1 can be adjusted based on the heat exchange capacity required by air conditioner A-1. When only range hood A-2 is operating, first air valve E-1 can be closed.

[0106] The second air valve E-2 is used to adjust the ventilation volume in the second air duct D-2, that is, to adjust the gas discharge volume of the range hood A-2; the second air valve E-2 can be adjusted to a greater extent according to the user's control of the range hood A-2. For example, when the user increases the air volume of the range hood A-2, the second air valve E-2 will be opened to a greater extent so that the gas discharge volume of the range hood A-2 can be increased; when only the air conditioner A-1 is working, the second air valve E-2 can be closed.

[0107] In this example, a gas flow meter F and an oil fume sensor G are respectively provided inside the first air duct D-1 and the second channel D-2; wherein, the gas flow meter F is provided inside the first air duct D-1, between the first air valve E-1 and the chamber, and can be used to detect the ventilation volume inside the first air duct D-1, and the heat exchange amount of the air conditioner A-1 can be obtained through the measurement result of the gas flow meter F; the oil fume sensor G is provided inside the second air duct D-2, between the range hood A-2 and the second air valve E-2, and is used to detect the ventilation volume inside the second air duct D-2, and the gas discharge volume of the range hood A-2 can be obtained according to the measurement result of the oil fume sensor G, and the opening and closing degree of the second air valve E-2 can be adjusted accordingly.

[0108] In this example, when the oil fume sensor G detects an increase in the gas displacement of the range hood A-2 in the second air duct D-2, the heat exchange of the air conditioner A-1 can be reduced by adjusting the opening and closing degree of the first air valve E-1, and the adjustment result of the heat exchange of the air conditioner A-1 can be detected according to the gas flow meter F; if the total gas displacement of the exhaust channel B has not yet reached the total gas displacement threshold, the speed of the induced draft fan C can be increased to increase the total gas displacement; in order to ensure the cooling effect of the air conditioner A-1, the power of the compressor of the air conditioner A-1 can be increased accordingly.

[0109] In this example, when the oil fume sensor G detects that the gas discharge volume of the range hood A-2 in the second air duct D-2 is reduced, the heat exchange capacity of the air conditioner A-1 can be increased by adjusting the opening and closing degree of the first air valve E-1, and the adjustment result of the heat exchange capacity of the air conditioner A-1 can be detected according to the gas flow meter F; the speed of the induced draft fan C can also be reduced to reduce the total gas discharge volume of the exhaust channel B; the power of the compressor of the air conditioner A-1 can be reduced accordingly to save energy.

[0110] In another implementation of this embodiment, the exhaust channel includes a chamber connected to the first air duct and the second air duct, and an exhaust air duct connected to the chamber; the valve includes a fan valve arranged in the chamber connected to the first air duct and the second air duct, and the fan valve is located between the first air duct and the second air duct, and can adjust the ventilation volume allocated to the first air duct and the second air duct by rotation. When the fan valve rotates toward the direction of the first air duct, the ventilation volume of the second air duct increases and the ventilation volume of the first air duct decreases; when the fan valve rotates toward the direction of the second air duct, the ventilation volume of the first air duct increases and the ventilation volume of the second air duct decreases; when the fan valve rotates to the first extreme position, the first air duct can be completely closed, and when it rotates to the second extreme position, the second air duct can be completely closed.

[0111] In this embodiment, the fan valve's rotation angle can be adjusted according to a fourth preset rule. For example, the fan valve can be adjusted based on the corresponding relationship between heat exchange and fan valve angle. Once the target heat exchange is determined, the fan valve's rotation angle can be determined. Alternatively, the fan valve can be rotated gradually until the heat exchange meets the adjustment target. For example, to increase the heat exchange, the fan valve can be gradually rotated toward the second air duct until the target ventilation volume is reached; to decrease the ventilation volume, the fan valve can be gradually rotated toward the first air duct until the target ventilation volume is reached.

[0112] It can be seen that the fan valve is a "linked" adjustment method. Adjusting the fan valve to reduce the ventilation volume of the first air duct will inevitably increase the ventilation volume of the second air duct, and vice versa. The method of providing the first and second air valves in the first and second air ducts respectively is an independent adjustment method. The two air valves can adjust the ventilation volume independently. Adjusting the first air valve to increase the ventilation volume of the first air duct does not necessarily change the ventilation volume of the second air duct. To change the ventilation volume of the second air duct, you need to adjust the second air valve separately.

[0113] An example of this embodiment is as follows Figure 3 As shown, the hot air exhausted by air conditioner A-1 is transported to exhaust duct B via first air duct D-1, while the cooking fumes exhausted by range hood A-2 are transported to exhaust duct B via second air duct D-2. Both the hot air and cooking fumes are discharged outdoors through exhaust duct B. An induced draft fan C is installed in exhaust duct B to direct the gases in the exhaust duct, including the hot air from first air duct D-1 and cooking fumes from second air duct D-2, outdoors.

[0114] In this example, the exhaust channel B includes a chamber connected to the first air duct D-1 and the second air duct D-2, and an exhaust air duct connected to the chamber; a fan valve H is provided between the first air duct and the second air duct in the chamber. Figure 3 It can be seen that the fan valve H can rotate in two directions.

[0115] When fan valve H is rotated toward first duct D-1, air flow from first duct D-1 to exhaust channel B becomes more obstructed, reducing airflow volume. This reduces the airflow through first duct D-1 and, consequently, reduces the heat exchange rate of air conditioner A-1. This also improves airflow from second duct D-2 to exhaust channel B, increasing airflow volume and airflow through second duct D-2. When fan valve H is rotated toward first duct D-1 to its extreme position, the first extreme position, fan valve H completely closes first duct D-1. Exhaust channel B now contains only air from second duct D-2, specifically, the exhaust fumes from range hood A-2.

[0116] Accordingly, when fan valve H rotates toward second air duct D-2, the airflow in first air duct D-1 increases, while the airflow in second air duct D-2 decreases. When fan valve H rotates to its second limit position, completely closing second air duct D-2, exhaust channel B now contains only air from first air duct D-1—that is, the hot air removed by air conditioner A-1.

[0117] In this example, the ventilation volume of first duct D-1 is positively correlated with the heat exchange capacity of air conditioner A-1. By rotating fan valve F to adjust the ventilation volume of first duct D-1, the heat exchange capacity of air conditioner A-1 can be adjusted accordingly. When only range hood A-2 is operating, the fan valve can be rotated to the first limit position, closing first duct D-1. The ventilation volume of second duct D-2 is positively correlated with the gas output of range hood A-2. When the gas output of the range hood is large, the ventilation volume of second duct D-2 can be increased by rotating fan valve F. When only air conditioner A-1 is operating, the fan valve can be rotated to the second limit position, closing second duct D-2.

[0118] In this example, a gas flow meter F and an oil fume sensor G are respectively installed inside the first air duct D-1 and the second channel D-2, which are used to detect the ventilation volume in the first air duct D-1 and the second channel D-2, respectively. According to the detection results, the heat exchange capacity of the air conditioner A-1 and the gas discharge capacity of the range hood A-2 can be respectively known.

[0119] In this example, when the oil fume sensor G detects an increase in the gas displacement of the range hood A-2 in the second air duct D-2, the heat exchange of the air conditioner A-1 can be reduced by rotating the fan valve H toward the first air duct D-1, and the adjustment result of the heat exchange of the air conditioner A-1 can be detected based on the gas flow meter F; if the total gas displacement of the exhaust channel B has not yet reached the total gas displacement threshold, the speed of the induced draft fan C can be increased to increase the total gas displacement; in order to ensure the cooling effect of the air conditioner A-1, the power of the compressor of the air conditioner A-1 can be increased accordingly.

[0120] In this example, when the oil fume sensor G detects that the gas discharge volume of the range hood A-2 in the second air duct D-2 is reduced, the heat exchange capacity of the air conditioner A-1 can be increased by rotating the fan valve H in the direction of the second air duct D-2, and the adjustment result of the heat exchange capacity of the air conditioner A-1 can be detected according to the gas flow meter F; the speed of the induced draft fan C can also be reduced to reduce the total gas discharge volume of the exhaust channel B; and the power of the compressor of the air conditioner A-1 can be reduced accordingly to save energy.

[0121] In this embodiment, the heat exchange amount of the air conditioner can be adjusted by a valve. In addition to the solutions in the above-mentioned implementation manner, other types of valves can also be applied in this embodiment.
