Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a range hood capable of distributing air volume, a range hood and stove linkage system, and a control method. Background Art

[0002] The working principle of the range hood is: driven by the fan, the air mixed with oil smoke in the room is sucked into the range hood cavity, and the air mixed with oil smoke is discharged to the outside or to a public flue through the exhaust pipe connected to the range hood. During the operation of the range hood, the operation of the fan drives the range hood to generate a negative pressure area near the air inlet set towards the stove. At this time, due to the pressure of the negative pressure area, the air mixed with oil smoke between the range hood and the stove can be discharged to the outside or to a public flue through the air inlet, the range hood cavity and the exhaust pipe.

[0003] The stove generally has multiple burners, and the range hood is provided with a corresponding air inlet toward each burner. When the range hood is started, the air inlets of the multiple range hoods are opened at the same time, and the fan is started to extract the oil smoke generated above the multiple burners.

[0004] Since users usually cook with one burner of the stove, it is necessary to extract the oil smoke above the burner. Or when using two burners for cooking, users only use one burner to cook (which produces more oil smoke). In this case, it is necessary to concentrate on extracting the more oil smoke above the burner used for cooking. However, the multiple air inlets that are open at the same time make it impossible for the range hood to quickly extract the more oil smoke at one burner, resulting in poor oil smoke extraction effect here. Summary of the invention

[0005] The purpose of the present invention is to provide a range hood, a range hood-stove linkage system and a control method capable of distributing air volume, aiming to solve the problem that the range hood cannot quickly extract more oil smoke at some stove heads.

[0006] In order to achieve the above object, the present invention adopts the following technical scheme:

[0007] In a first aspect, the present invention provides a range hood capable of distributing air volume, comprising a smoke collecting hood, a fan assembly and a damper assembly. The smoke collecting hood has a smoke collecting chamber, an air outlet and a plurality of air inlets, and the fan assembly is used to drive air into the smoke collecting chamber from the air inlet and blown out from the air outlet. The damper assembly comprises a plurality of damper members, the plurality of damper members are arranged in a one-to-one correspondence with the plurality of air inlets, and one damper member is installed close to one air inlet, and is used to adjust the opening area of ​​the air inlet.

[0008] The damper assembly is configured to have an initial position state and an air adjustment position state. When the damper assembly is in the initial position state, the plurality of damper members cause the plurality of air inlets to be in an open state. When the fan assembly is started and the damper assembly is in the air adjustment position state, the plurality of damper members cause at least one air inlet to be in an air adjustment state with a reduced opening area or closed, and at least one air inlet is in an open state.

[0009] Since the damper assembly is in the initial position so that multiple air inlets are in an open state, when all the stoves are turned on, the range hood can be directly started to extract oil smoke and other particles without additional adjustment of the damper assembly, which is more convenient. In addition, when the fan assembly is in the start-up state, the damper assembly in the wind adjustment position can make some air inlets in an open state without obstruction, and the other part of the air inlets in a wind adjustment state with a reduced or closed opening area (i.e., the opening area is zero). That is, the opening area of ​​a part of the air inlets remains unchanged (i.e., in the open state), and the opening area of ​​the other part of the air inlets can be reduced or even zero. In this way, the negative pressure area at the air inlet in the open state has a greater extraction capacity for the nearby air, so that more oil smoke and other particles above the corresponding stove can quickly pass through the air inlet into the smoke collecting chamber and be discharged outdoors or to the public flue, thereby improving the range hood's ability to quickly extract oil smoke and other particles near a certain part of the stove, so as to avoid the rapid diffusion of oil smoke and other particles during cooking processes such as stir-frying.

[0010] Compared with all air inlets being in an open state, by reducing the opening area of ​​some air inlets or closing some air inlets, the opening area of ​​the smoke collecting chamber on the air inlet side can be reduced, which is beneficial to increase the air inflow speed on the air inlet side of the smoke collecting chamber while keeping the speed of the fan assembly unchanged. That is, the air inlet above the stove where cooking operations with large oil smoke such as stir-frying are performed can be in an open state, and the air inlets at other stoves that are not used or have less oil smoke are in a state with reduced opening area or closed. While ensuring that the opening area of ​​the air inlet at the place with large oil smoke and other particles remains unchanged, the speed at which air mixed with oil smoke and other particles flows into the air inlet can be increased to improve the extraction and discharge effect of large oil smoke and other particles.

[0011] In a second aspect, the present invention further provides a smoke and stove linkage system, which comprises a stove and a range hood capable of distributing air volume in the first aspect. The stove comprises a first stove head and a second stove head, and the first stove head and the second stove head are arranged at intervals. The first air inlet is arranged toward the first stove head, and the second air inlet is arranged toward the second stove head.

[0012] The range hood is configured as:

[0013] When the first stove and the second stove are ignited, the damper assembly is in the initial position state, and the fan assembly is started. When the first stove is ignited and the second stove is not ignited, the damper assembly is in the air adjustment position state, the air inlet toward the first stove is in an open state, the air inlet toward the second stove is in the air adjustment state, and the fan assembly is started. When the second stove is ignited and the first stove is not ignited, the damper assembly is in the air adjustment position state, the air inlet toward the second stove is in an open state, the air inlet toward the first stove is in the air adjustment state, and the fan assembly is started.

[0014] Since the smoke and stove linkage system provided in the embodiment of the present application extracts particulate matter such as oil smoke through the range hood capable of distributing air volume in the first aspect, the two can solve the same technical problem and achieve the same technical effect.

[0015] In a third aspect, the present invention further provides a control method for a smoke stove linkage system, comprising:

[0016] When the ignition signals of the first stove and the second stove are received or the ignition signals of the first stove and the second stove are not received, the damper assembly is controlled to be in an initial position state so that the multiple air inlets are in an open state.

[0017] When an ignition signal of the first stove head is received but an ignition signal of the second stove head is not received, the damper member is controlled to put the air inlet toward the second stove head in an air adjustment state and put the air inlet toward the first stove head in an open state.

[0018] When the ignition signal of the second stove is received but the ignition signal of the first stove is not received, the damper is controlled so that the air inlet toward the first stove is in an air adjustment state and the air inlet toward the second stove is in an open state.

[0019] Since the control method of the smoke / stove linkage system provided in the embodiment of the present application is used to control the smoke / stove linkage system in the second aspect, the two can solve the same technical problem and achieve the same technical effect.

[0052] A range hood, also known as a range hood or exhaust hood, is a kitchen appliance that purifies the kitchen environment. The range hood can quickly remove the fumes, combustion exhaust gas and particulate matter generated during the burning of the stove and cooking, and discharge them to the outdoors or to a public flue, thereby purifying the indoor air to reduce indoor air pollution, and has a safety guarantee function of anti-toxicity and explosion-proof.

[0053] The process of extracting oil smoke by the range hood follows the principle of air fluid mechanics: in two adjacent spatial areas, as long as there is a pressure difference, the gas will flow from the high pressure area to the low pressure area. When the range hood is in operation, the air in the range hood is discharged to the outside or the public flue, so that a negative pressure area with a large pressure difference between the range hood and the surrounding area is formed. During the process of cooking oil smoke rising, the air mixed with oil smoke will be affected by the pressure of the negative pressure area and sucked into the range hood and discharged.

[0054] Based on this, Figure 1 As shown, Figure 1 A schematic diagram of the three-dimensional structure of a smoke and stove linkage system 100 provided in an embodiment of the present application. The smoke and stove linkage system 100 may include a range hood for distributing air volume (hereinafter referred to as the range hood 10) and a stove 20, and the stove 20 may include a first stove head 21 and a second stove head 22 distributed at intervals, for heating cooking ingredients, such as the first stove head 21 and the second stove head 22 may be distributed at intervals along the left and right directions.

[0055] The range hood 10 and the stove 20 may be of a split structure, that is, the range hood 10 may be installed above the stove 20 to extract and discharge the fumes generated during the use of the stove 20 to the outside or a public flue. In this case, the range hood 10 may be a side suction range hood or a top suction range hood, etc., without limitation.

[0056] Alternatively, the range hood and the stove 20 may be an integrated structure, such as an integrated stove. In this case, the main structure of the range hood 10 may be located below the stove 20, but one or more air inlets may be provided laterally above the stove 20, so that the range hood 10 can extract oil smoke and other particulate matter generated during cooking by the first stove 21 and / or the second stove 22 through the air inlets.

[0057] For example, Figure 1 As shown, the range hood 10 may include a fume hood 11 and a fan assembly 12. Figure 2 and Figure 3 The smoke collecting hood 11 may include a plurality of shell plates that enclose a smoke collecting chamber 111 , as well as an air outlet 112 and a plurality of air inlets 113 that are connected to the smoke collecting chamber 111 , so that the fan assembly 12 can drive air to enter the smoke collecting chamber 111 through the air inlet 113 and blow air out of the smoke collecting chamber 111 through the air outlet 112 .

[0058] like Figure 2 and Figure 3 As shown, multiple air inlets 113 can be arranged below the smoke collecting hood 11. Taking the multiple air inlets 113 being located at one side of the smoke collecting chamber 111, which is the front side, as an example, the air outlet 112 can be opened above the smoke collecting hood 11. Figure 1 The fan assembly 12 can be installed above the smoke collecting hood 11, and the fan assembly 12 can be connected to the smoke collecting chamber 111 through the air outlet 112, so that the oil smoke and other particulate matter at the stove 20 can be discharged to the outside or the public flue through the air inlet 113, the smoke collecting chamber 111, the air outlet 112 and the fan assembly 12 in sequence.

[0059] In the above embodiment, the smoke hood 11 can be used as a side suction structure. Alternatively, the smoke hood can also be used as a side suction structure, in which case a plurality of air inlets 113 can be opened at the lower side of the smoke hood 11, and the smoke hood 11 can be located above the stove 20 in the up and down direction to collect and extract the oil smoke above the stove 20.

[0060] Taking the smoke hood 11 as a side suction structure as an example, when the smoke collecting cavity 111 formed by the smoke hood 11 has sufficient internal space, the fan assembly 12 can also be installed in the smoke collecting cavity 111. In this case, the smoke exhaust pipeline can be directly connected to the smoke hood 11 corresponding to the air outlet 112 to guide particulate matter such as oil smoke to the outdoors or a public flue, which has a good structural integration.

[0061] Take the case where the fan assembly 12 is installed above the smoke hood 11 as an example. Figure 4 As shown, the fan assembly 12 may include a fan housing 121 and an exhaust fan 122. Figure 5 The fan housing 121 may enclose a fan cavity 1211 for installing the exhaust fan 122 , and the fan housing 121 may also be provided with an air inlet 1212 and an air outlet 1213 connected to the fan cavity 1211 .

[0062] For example, Figure 5 As shown, the fan housing 121 may have an air inlet 1212 at the lower side of the fan chamber 1211 for connecting to the smoke collecting hood 11 (such as Figure 3 Correspondingly, an exhaust port 1213 can be opened on the upper side of the fan housing 121 to connect the smoke exhaust pipeline to guide the particulate matter such as oil smoke to the outdoors or the public flue.

[0063] Alternatively, the exhaust port 1213 may also be provided at the rear side or the left and right sides of the fan housing 121, which is not limited thereto. The exhaust fan 122 may be a centrifugal fan, an axial flow fan, a diagonal flow fan or a cross flow fan, which may exhaust particulate matter such as oil smoke from the top of the stove 20 through the exhaust pipes at the air inlet 113, the smoke collecting chamber 111, the air outlet 112, the air inlet 1212, the fan chamber 1211 and the exhaust port 1213 to the outside or a public flue.

[0064] like Figure 1 As shown, taking the fan assembly 12 installed above the smoke hood 11 as an example, combined with Figure 4 The fan assembly 12 may further include a decorative cover 123. The decorative cover 123 may include a front side plate and two side plates connected to the left and right sides of the front side plate, the rear ends of the two side plates may be connected to the left edge and the right edge of the front side plate, and the fan housing 121 may be installed in the space between the two side plates, so that the decorative cover 123 may shield the fan housing 121 forward, leftward, and backward to prevent it from being exposed.

[0065] In some embodiments, in order to facilitate the connection and installation of the smoke exhaust duct, such as Figure 5 As shown, the fan assembly 12 may further include a smoke guide connector 124. The lower end of the smoke guide connector 124 may be connected to the fan housing 121 at the exhaust port 1213, and the upper end of the smoke guide connector 124 may be provided with a plurality of annular structures connected to the smoke exhaust pipe, so as to facilitate plugging and adapting to smoke exhaust pipes of different calibers, and enable the smoke exhaust pipe to be connected and communicated with the exhaust port 1213 through the smoke guide connector 124.

[0066] Take the smoke hood 11 as a side suction structure as an example. Figure 2 and Figure 3 As shown, the range hood 10 may further include a smoke collecting plate 131, which may be installed on a side of the air inlet 113 away from the smoke collecting chamber 111 along the air flow direction. The upper edge of the smoke collecting plate 131 may be hingedly installed with the smoke collecting hood 11 to open or close multiple air inlets 113.

[0067] For example, Figure 2 and Figure 3 As shown, the lower edge of the smoke collecting plate 131 can be rotated to a position away from the smoke collecting hood 11, so that the multiple air inlets 113 at the smoke collecting hood 11 are in an open state, and the unfolded smoke collecting plate 131 can also prevent the oil smoke and other particles below from flowing upward. Figure 6 As shown, the position of the lower edge of the smoke collecting plate 131 relative to the smoke collecting hood 11 can also be adjusted by reverse rotation, so that the smoke collecting plate 131 can close the multiple air inlets 113 at the smoke collecting hood 11 .

[0068] In some embodiments, Figure 2and Figure 7 As shown, the range hood 10 may further include a plurality of smoke collecting hinges 132. One end of the smoke collecting hinge 132 may be connected to the upper edge of the smoke collecting plate 131, and the plurality of smoke collecting hinges 132 may be spaced apart on the smoke collecting plate 131 along the left-right direction, and the other end of the smoke collecting hinge 132 may be located in the smoke collecting chamber 111 and connected to the smoke collecting hood, so that the smoke collecting plate 131 may rotate relative to the smoke collecting hood 11 through the smoke collecting hinge 132.

[0069] Continue to refer to Figure 2 and Figure 7 The range hood 10 may further include a smoke collecting driving member 133, which may be located in the smoke collecting chamber 111 and connected to the smoke collecting hood 11. The smoke collecting driving member 133 may be disposed near one of the smoke collecting hinges 132, and a driving end of the smoke collecting driving member 133 may be drivingly connected to the smoke collecting hinge 132, so as to drive the smoke collecting hinge 132 to rotate to open or close the smoke collecting plate 131.

[0070] In addition, the upper edge of the smoke collecting plate 131 can be rotatably connected to the smoke collecting cover 11 through a hinge or other structure. Then, the smoke collecting plate 131 can be opened or closed by the driving screw under the drive of the smoke collecting driving member 133.

[0071] Exemplarily, the first end of the transmission screw can be connected to the position of the smoke collecting plate 131 near the lower edge, and the first end of the transmission screw can be rotated relative to the smoke collecting plate 131 and slidably displaced along the width direction of the smoke collecting plate 131 (the length direction of the smoke collecting plate 131 is the left-right direction). Correspondingly, the second end of the transmission screw can be connected to the transmission end of the smoke collecting drive member 133 through a sleeve with an internal thread, and the smoke collecting drive member 133 and the sleeve can be arranged to be rotatably installed around an axis parallel to the left-right direction, so that the first end of the transmission screw can extend out of the smoke collecting chamber 111 to open the smoke collecting plate 131, and the first end of the transmission screw can be retracted into the smoke collecting chamber 111 to close the air inlet 113 of the smoke collecting plate.

[0072] Based on this, Figure 1 As shown, the range hood 10 may further include an electrical box 14, which may be located on the upper side of the fan assembly 12, and the electrical box 14 may be connected to the fan housing 121 (such as Figure 4 As shown) so that the decorative cover 123 can also cover the electrical box 14.

[0073] For example, a control circuit board may be provided in the electrical box 14, and the control circuit board may be electrically connected to the exhaust fan 122 and the smoke collecting drive 133. The range hood 10 may further include a control circuit board connected to the control circuit board, and the control circuit board may be installed in the electrical box so that the user can control the operation state of the range hood through a remote signal such as a remote control, or the control circuit board may be installed on the decorative panel of the smoke collecting hood 11 on the upper side or the front side of the smoke collecting plate 131, so that the user can control the operation state of the range hood 10 through the control circuit board.

[0074] The control circuit board can control the smoke trapping driving member 133 to rotate to open the multiple air inlets 113, and the control circuit board can also control the smoke trapping driving member 133 to rotate in the opposite direction to make the smoke trapping plate 131 close the multiple air inlets 113. When the smoke trapping plate 131 opens the multiple air inlets 113, the control circuit board can start the exhaust fan 122 to extract and discharge the oil smoke with the range hood 10, and the control circuit board can also adjust the exhaust volume per unit time at the air inlet 113 by adjusting the operating power of the exhaust fan 122.

[0075] When the control circuit board controls the exhaust fan 122 to stop rotating, the control circuit board can control the smoke collecting drive 133 to rotate in the opposite direction so that the smoke collecting plate 131 closes the multiple air inlets 113, so that the range hood 10 stops running or is in a standby state.

[0076] Based on this, combined Figure 1 and Figure 3 When installing the cooker 20 and the range hood 10, the first stove 21 and the second stove 22 are spaced apart in the left and right direction. A plurality of air inlets 113 may be located above the cooker 20, and one air inlet 113 may be close to or aligned with one cooker to install the range hood 10.

[0077] Based on this, the user can use one stove head to perform operations such as steaming or frying when using the stove 20 for cooking. In this way, particulate matter such as oil smoke during cooking will be concentrated near the first stove head 21 or the second stove head 22.

[0078] Alternatively, the user can also use the first stove 21 and the second stove 22 for cooking at the same time, such as using the first stove 21 for steaming and using the second stove 22 for cooking. In this case, particulate matter such as oil smoke during cooking will be concentrated at the second stove 22.

[0079] In the above two application scenarios, the oil smoke and other particles above the stove 20 will be concentrated on one side of the first stove head 21 or the second stove head 22. When the oil smoke and other particles above the stove 20 are extracted through the range hood 10, since the opening areas of the two air inlets 113 after the smoke collecting plate 131 is opened are the same, that is, a negative pressure area with similar pressure will be formed at the two air inlets 113, the range hood 10 has the same oil smoke extraction state above the first stove head 21 and the second stove head 22 through the two air inlets 113, that is, the two air inlets 113 opened at the same time cannot concentrate (or quickly) extract more oil smoke and other particles at one of the stove heads, resulting in a poor oil smoke extraction effect at the stove head with more oil smoke and other particles.

[0080] In order to solve the above problems, Figure 7 As shown, the range hood 10 may further include a damper assembly 15, and the damper assembly 15 may include a plurality of damper members 151. Figure 8 , multiple damper members 151 can be arranged in one-to-one correspondence with multiple air inlets 113, and one damper member 151 can be installed close to one air inlet 113, so that the damper member 151 can open or close the air inlet 113, or the damper member 151 can also reduce the opening area of ​​the corresponding air inlet 113.

[0081] Based on this, the damper assembly 15 can be configured to have an initial position state and an air adjustment position state, so as to adjust the opening area of ​​the corresponding air inlet 113 .

[0082] Exemplary, combined Figure 2 and Figure 7 When the damper assembly 15 is in Figure 2 In the initial position state shown, multiple (such as all) air inlets 113 can be in an open state, such as a state where the opening area of ​​the air inlet 113 is the largest (i.e., the damper member 151 does not block the air inlet 113). Figure 1 When the air intake device 110 is started (as shown in the figure), a negative pressure zone with approximately the same pressure can be formed at the multiple air inlets 113, so that particulate matter such as oil smoke above multiple stoves (such as the first stove 21 and the second stove 22) can be extracted more evenly. The damper assembly 15 in the initial position state can also be used for the initial reset of multiple damper members 151.

[0083] Correspondingly, when Figure 1 The fan assembly 12 is shown to be activated and the damper assembly 15 is in Figure 7 and Figure 8In the air adjustment position state shown, the displacement of one or more damper members 151 in the left-right direction can be adjusted so that at least one air inlet 113 is in an air adjustment state with a reduced or closed opening area, and at least one air inlet 113 is in an open state. For example, the right air inlet 113 corresponding to the second stove 22 can be in an open state, and the left air inlet 113 corresponding to the first stove 21 can be reduced or closed in opening area.

[0084] When the fan assembly 12 is in the start-up state, the damper assembly 15 in the air adjustment position state can make the right air inlet 113 in an open state without obstruction, and the left air inlet 113 is in an air adjustment state with a reduced or closed opening area (i.e., the opening area is zero), that is, the opening area of ​​the left air inlet 113 can be reduced or even zero, while the opening area of ​​the right air inlet 113 remains unchanged (i.e., open state). In this way, the negative pressure area at the right air inlet 113 has a greater extraction capacity for the nearby air, so that more oil smoke and other particles above the right stove (i.e., the second stove 22) can quickly pass through the right air inlet 113 into the smoke collecting chamber 111 and be discharged, thereby improving the range hood 10's ability to quickly extract oil smoke and other particles near a certain part of the stove, so as to avoid the rapid diffusion of oil smoke and other particles during cooking such as stir-frying.

[0085] Compared with all the air inlets 113 being in an open state, by reducing the opening area of ​​some of the air inlets 113 or closing some of the air inlets 113, the opening area of ​​the smoke collecting chamber 111 on the air inlet side can be reduced, which is beneficial to increase the air inflow speed on the air inlet side of the smoke collecting chamber 111 while keeping the speed of the fan assembly 12 unchanged. That is, the air inlet 113 above the stove where cooking operations with large oil smoke such as stir-frying are performed can be opened, and the air inlet 113 at other stoves that are not used or have less oil smoke is in a state with a reduced opening area or closed. While ensuring that the opening area of ​​the air inlet 113 at the large oil smoke and other particles remains unchanged, the speed at which air mixed with oil smoke and other particles flows into the air inlet 113 can be increased to improve the extraction and discharge effect of large oil smoke and other particles.

[0086] For example, the range hood 10 includes two air inlets 113 spaced apart in the left-right direction, and the stove 20 of the range hood linkage system 100 is provided with a first stove 21 and a second stove 22. The first stove 21 and the second stove 22 can be spaced apart in the left-right direction, one air inlet 113 can be arranged toward the first stove 21, and the other air inlet 113 can be arranged toward the second stove 22. Based on this, the range hood 10 can be configured to be in a coordinated state with the first stove 21 and the second stove 22.

[0087] When the first stove 21 is ignited and the second stove 22 is not ignited, the range hood 10 can be started synchronously to put the damper assembly 15 in the wind adjustment position and start the fan assembly 12, that is, by adjusting and controlling the two damper components 151, the air inlet 113 toward the first stove 21 can be in an open state, and the air inlet 113 toward the second stove 22 can be in a wind adjustment state with a reduced opening area or closed. In this way, the oil smoke and other particles generated above the first stove 21 can be quickly extracted through the air inlet 113 toward the first stove 21 to prevent the diffusion of the oil smoke and other particles from affecting the indoor air quality.

[0088] When the second stove 22 is ignited and the first stove 21 is not ignited, the range hood 10 can be started synchronously to put the damper assembly 15 in the wind adjustment position and start the fan assembly 12, that is, by adjusting and controlling the two damper components 151, the air inlet 113 toward the second stove 22 can be in an open state, and the air inlet 113 toward the first stove 21 can be in a wind adjustment state with a reduced opening area or closed. In this way, the oil smoke and other particles generated above the second stove 22 can be quickly extracted through the air inlet 113 toward the second stove 22 to prevent the diffusion of the oil smoke and other particles from affecting the indoor air quality.

[0089] When the first stove 21 and the second stove 22 are in the ignition state at the same time, the range hood 10 can be started synchronously to make the damper assembly 15 in the initial position state and start the fan assembly 12, that is, by controlling the two damper components 151 to be in the initial position or reset, the two air inlets 113 can be opened. In this way, the range hood 10 can extract and discharge the oil smoke and other particles above the first stove 21 and the second stove 22 through the two air inlets 113 at the same time.

[0090] Correspondingly, when the first stove head 21 and the second stove head 22 are in the unignited state, the corresponding range hood 10 can be synchronously in the closed state, and the damper assembly 15 can be in the initial position state at this time. That is, when the range hood 10 is turned off from the start state, the damper assembly 15 can be controlled to adjust from other position states to the initial position state, so that the initial position state and the air adjustment position state of the damper assembly 15 can be quickly and flexibly adjusted when the range hood 10 is started next time.

[0091] It should be noted that since the damper assembly 15 can have a plurality of different air adjustment position states, for example, the damper member 151 can be adjusted to make a certain air inlet 113 in a partially blocked state with a reduced opening area. Alternatively, the damper member 151 can be adjusted to make the air inlet 113 in a closed state with a zero opening area, which is not limited thereto.

[0092] In combination with the configuration scheme of the smoke and stove linkage system 100, when one of the stove heads is in the ignition state and the other stove head is in the non-ignition state, the air adjustment position state of the damper assembly 15 can be configured to completely close the air inlet 113 in the air adjustment position state, so that the air inlet 113 in the open state can quickly and effectively extract particulate matter such as oil smoke.

[0093] In addition, when the first stove 21 and the second stove 22 are in the ignition state, if one of the stoves is used for cooking operations with large oil smoke, such as cooking, the range hood 10 can be configured to have a stir-fry gear state.

[0094] For example, when the range hood 10 is in the stir-fry gear state, the priority of the stir-fry gear state may be higher than the ignition monitoring control sequence of the stove, and the damper assembly 15 may be in the wind adjustment position state. So that the corresponding air inlet 113 is in an open state, cooking operations with large oil smoke such as cooking can be performed through the stove corresponding to the inlet 113, and other air inlets 113 may be in the wind adjustment position state, and correspondingly, the fan assembly 12 may operate at rated power.

[0095] If the range hood 10 has multiple stir-fry gear states, a stir-fry gear state can be configured to correspond to an air inlet 113. That is, by selecting a different stir-fry gear state to open, cooking operations with large oil smoke such as cooking can be performed at the stove head corresponding to the air inlet 113.

[0096] In some embodiments, Fig. 9 As shown, the range hood 10 may further include an oil filter 16, which may be installed on the fume hood 11 away from the air outlet 112 along the air flow direction (eg Figure 3 The oil filter 16 can be connected and installed with the smoke collecting hood 11. The oil filter 16 can be a sheet-like structure or a plate-like structure. In a first straight line direction perpendicular to the oil filter 16, the oil filter 16 can be provided with a plurality of first through holes 161, and the plurality of first through holes 161 are used to communicate with the smoke collecting chamber 111, and some of the first through holes 161 can form an air inlet 113.

[0097] Exemplary, combined Fig. 9 The smoke collecting hood 11 can be located away from the air outlet 112 (eg Figure 3 A vent hole 114 is provided at the position of the oil filter 16, and the oil filter 16 can be connected to the smoke collecting hood 11 at the edge of the vent hole 114 by screws, welding or clamping. At this time, the air inlet 113 composed of a plurality of first through holes 161 on the oil filter 16 can be connected to the smoke collecting chamber 111.

[0098] The first straight line direction may be parallel to the front-to-back direction, and the axis of the vent hole 114 may also be parallel to the front-to-back direction. Alternatively, the first straight line direction may also have an angle with the front-to-back direction, and the axis of the vent hole 114 may be parallel to the first straight line direction, and from the smoke collecting chamber 111 toward the vent hole 114, the vent hole 114 may be opened obliquely downward.

[0099] On the oil filter 16, a plurality of first through holes 161 opened along the first straight line direction can be spaced apart on the oil filter 16. The shape of the first through hole 161 can be any shape of a circular hole, an elliptical hole, a triangular hole, a rectangular hole, a square hole, a polygonal hole and a strip hole, and is not limited thereto.

[0100] Based on this, Fig.10 As shown, the damper member 151 can be arranged close to the oil filter member 16, such as the damper member 151 can be installed on the inner side of the oil filter member 16 facing the smoke collecting chamber 111, and the damper member 151 can be slidably installed along the second linear direction (perpendicular to the first linear direction) relative to the oil filter member 16. One damper member 151 can be arranged corresponding to one air inlet 113, and the damper member 151 can be provided with a plurality of second through holes 152, and the plurality of second through holes 152 on one damper member 151 can be arranged corresponding to the plurality of first through holes at one air inlet 113, so that the damper member 151 can make the air inlet 113 in an open state or a wind-adjusting state during the sliding process along the second linear direction.

[0101] Exemplarily, when the damper 151 is in the initial position so that the air inlet 113 is in an open state, along the first straight line direction, the multiple second through holes 152 of the damper 151 can be aligned and connected with the multiple first through holes 161 at the corresponding air inlet 113, so that the smoke collecting chamber 111 can extract particulate matter such as oil smoke through the second through holes 152 and the first through holes 161. When the damper 151 moves along the second straight line direction so that the multiple second through holes 152 of the damper 151 and the multiple first through holes 161 at the corresponding air inlet 113 are partially or completely misaligned in the first straight line direction, the corresponding air inlet 113 can be in a wind adjustment state in which the opening area is reduced or closed.

[0102] It should be noted that, in the embodiment of the present application, taking the example of a plurality of first through holes 161 on the oil filter 16 forming two air inlets 113, the two air inlets 113 can be spaced apart in the left-right direction. Correspondingly, the second straight line direction can be the left-right direction, that is, the damper 151 can be slidably installed relative to the oil filter 16 in the left-right direction.

[0103] Alternatively, the second straight line direction may be perpendicular to the first straight line direction and may also have an angle with the left-right direction. For example, the second straight line direction may also be perpendicular to the first straight line direction and the left-right direction at the same time. In this case, if the oil filter 16 is arranged obliquely, the damper 151 may slide upward or downward on the inclined surface of the oil filter 16 along the second straight line direction, so that the corresponding air inlet 113 may be flexibly adjusted between the open state and the air adjustment state.

[0104] Continue to refer to Fig.10 , taking the case where two air inlets 113 are spaced apart in the left-right direction as an example, the first through hole 161 may be a strip hole, the first through hole 161 may extend along the third straight line direction, the length direction of the strip hole may be the third straight line direction, and the width direction of the strip hole may be the second straight line direction. At this time, the second straight line direction (such as the length direction of the oil filter 16) may be parallel to the left-right direction, and the third straight line direction (such as the width direction of the oil filter 16) may be perpendicular to the first straight line direction and the second straight line direction.

[0105] At one air inlet 113, the plurality of first through holes 161 may be spaced apart along a second straight line direction (such as the left-right direction), and the plurality of second through holes 152 may be a strip-shaped hole structure corresponding to the plurality of first through holes 161, so that the damper member 151 may adjust the air inlet 113 to be in an open state or a wind-adjusting state. The plurality of second through holes 152 on one damper member 151 and the plurality of first through holes 161 at one air inlet 113 may have the same shape, size, number, and spacing position.

[0106] Thus, when the damper 151 makes the air inlet 113 open, the plurality of first through holes 161 at one air inlet 113 can be aligned with the plurality of second through holes 152 in the first straight line direction, that is, the plurality of first through holes 161 can be fully unfolded at this time, so that the air inlet 113 can have the largest air inlet area. When the damper 151 moves in the left-right direction to make the air inlet 113 in the air adjustment state, the first through holes 161 and the second through holes 152 can be partially or completely misaligned in the first straight line direction according to the movement amount of the damper 151, so as to reduce the opening area of ​​the air inlet or completely close it.

[0107] It should be noted that, in the above embodiment, if the damper member 151 can completely close the air inlet 113, the spacing dimension between two adjacent first through holes 161 in the second straight line direction needs to be greater than or equal to the width dimension of the first through hole 161 in the second straight line direction. And the spacing dimension between two adjacent second through holes 152 in the left-right direction also needs to be greater than or equal to the width dimension of the second through hole 152 in the second straight line direction, so that when the first through hole 161 and the second through hole 152 are completely misaligned, the damper member 151 can close the air inlet 113.

[0108] In this way, when the damper member 151 is controlled to slide along the width direction of the strip hole to adjust the air inlet 113 between the air adjustment state and the open state, the state of the air inlet 113 can be changed with a shorter stroke, which is more convenient than sliding the damper member 151 along the length direction of the strip hole.

[0109] Moreover, compared with setting the first through hole 161 and the second through hole 152 as through hole structures of other shapes, the strip-shaped hole is convenient for opening or closing the air inlet 113 , while being beneficial for reducing the number of through holes and increasing the opening area of ​​the air inlet 113 .

[0110] In some other embodiments, such as Fig.11 As shown, two air inlets 113 spaced apart in the left-right direction may be opened forwardly below the smoke collecting hood 11 , that is, one air inlet 113 may be a through-hole structure connected to the smoke collecting chamber 111 .

[0111] Based on this, the damper member 151 can be installed at the edge of the air inlet 113 through a hinge structure, and the damper member 151 can be located at the inner side of the air inlet 113 close to the smoke collecting chamber 111, or the damper member 151 can be located at the outer side of the air inlet 113 away from the smoke collecting chamber 111. Then, the air inlet can be opened and adjusted by rotating the damper member 151.

[0112] It should be noted that, in the embodiment of the present application, the damper assembly 15 can be located on the side of the oil filter 16 close to the smoke collecting chamber 111. The damper assembly 15 can also be located on the outside of the oil filter 16 away from the smoke collecting chamber 111. In this case, if the smoke collecting hood 11 is connected with a smoke collecting plate 131, the damper assembly 151 can be located between the smoke collecting plate 131 and the oil filter 16 to avoid affecting the opening or closing state of the damper assembly 151 and the smoke collecting plate 131.

[0113] In order to facilitate the installation of the damper member 151 sliding along the second straight line direction, as shown in FIG. Fig.12 As shown, the damper assembly 15 may further include a plurality of first guide portions 153 and a plurality of second guide portions 154. Along the third straight line direction (Z direction), at an air inlet 113 (such as Fig.10A first guide portion 153 is provided on at least one side of the outer surface of the housing 10 (as shown), and the first guide portion 153 can be connected to the smoke collecting hood 11 or the oil filter 16.

[0114] Corresponding, combined Fig.12 , at one damper member 151, along the third straight line direction (X direction), a second guide portion 154 is provided on one side of the damper member 151 close to the first guide portion 153. The second guide portion 154 may be connected to the damper member 151, such as the second guide portion 154 may be located on the side of the damper member 151 facing the oil filter member 16 along the first straight line direction (Y direction), and the second guide portion 154 is connected and matched with the first guide portion 153, so that the damper member 151 is slidably installed relative to the oil filter member 16 along the second straight line direction (i.e., the left-right direction).

[0115] Exemplarily, the first guide portion 153 may be a guide groove, such as the first guide portion 153 with a guide groove structure extending along the second straight line direction may be installed on both sides of the air inlet 113 along the third straight line direction, such as the first guide portion 153 may be positioned and connected with the oil filter 16 or the smoke hood 11. Correspondingly, the second guide portion 154 may be a plug-in column, and the second guide portion 154 with a plug-in column structure may be installed on both side edges of the damper member 151 along the third straight line direction.

[0116] Combination Fig.13 , along the first straight direction (Y direction), the first guide portion 153 can be installed between the damper member 151 and the oil filter member 16. Along the first straight direction, one end of the second guide portion 154 can be connected to the damper member 151, and one end of the second guide portion 153 can be plugged and installed with the first guide portion 153 of the guide rail groove structure to prevent the damper member 151 from being separated from the first guide portion 153 along the first straight direction, and the damper member 151 can be slidably installed in the left and right directions.

[0117] In order to prevent the damper member 151 from being separated from the first guide portion 153 along the first straight line direction, Fig.13 , on the opposite sides of the first guide portion 153 of the guide rail groove structure in the third straight line direction (i.e., the Z direction), at the edges of the opposite sides of the groove structure close to the damper member 151 in the Y direction, the two edges can be bent close to each other in the third straight line direction to form a flange structure. Correspondingly, the end of the second guide portion 154 of the plug-in column structure close to the oil filter 16 along the Y direction can form a convex structure that cooperates with the flange, so that the convex structure located in the guide rail groove prevents the damper member 151 from being separated from the first guide portion under the limit of the flange.

[0118] Based on this, combined Fig.12In order to facilitate the plugging and installation of the second guide portion 154 and the first guide portion 153 along the third straight line direction, a notch can be partially opened at the first guide portion 153 of the flange structure to avoid the protruding structure of the second guide portion 154 along the Y direction.

[0119] When the protruding structure of the second guide portion 154 is inserted into the guide rail groove, the damper member 151 can be slid in the left-right direction so that the protruding structure of the guide portion 154 is misaligned with the notch in the Y direction, thereby preventing the second guide portion 154 from separating from the first guide portion 153 in the Y direction.

[0120] In the above embodiment, the first guide portion 153 can be an integrated structure with the oil filter 16 or the smoke hood 11, or can be two independent components, which is not limited. If the first guide portion 153 is an independent component, the first guide portion 153 can be a guide rail with a guide rail groove structure, and the length direction of the guide rail is the left-right direction.

[0121] In addition, the guide rail groove structure and the plug-in column structure can also be provided in different directions. For example, the first guide portion 153 can be a plug-in column structure, and the second guide portion 154 can be a guide rail groove structure, which can also meet the plug-in installation of the damper member 151 and the oil filter member 16, and enable the damper member 151 to be slidably installed relative to the oil filter member 16 in the left-right direction.

[0122] In some embodiments, Fig.12 and Fig.14 As shown, the damper assembly 15 may further include a reset member 155, a drive motor 156 and a transmission arm 157. The transmission arm 157 may be connected to the output shaft of the drive motor 156, and the transmission arm 157 may be located between the two damper members 151 along the second straight line direction (left-right direction), so that the drive motor 156 can drive the damper members 151 to adjust the air inlet 113 (such as Fig.10 As shown) is in the open state and the air adjustment state.

[0123] It should be noted that in Fig.12 and Fig.14 In the illustrated embodiment, a reset member 155 may be installed between the first guide portion 153 and the second guide portion 154 to act on the damper member 151 to open the air inlet 113 in a natural state. Exemplarily, the reset member 155 may also be installed between the second guide portion 154 and the oil filter member 16 (or the smoke hood), or the reset member 155 may also be installed between the first guide portion 153 and the damper member 151, such as one or more reset members 155 may be provided between a damper member 151 and the oil filter member 16 (or the smoke hood 11), to act on the damper member 151 to open the air inlet 113 in a natural state.

[0124] When the damper member 151 is acted on by the reset member 155 so that the air inlet 113 is in an open state in the natural state (the damper member 151 is removed), the damper assembly 15 may further include a stopper, which may be installed between the first guide portion 153 and the second guide portion 154. When the damper member 151 slides to the air inlet 113 in the air adjustment state under the action of the reset member 155, the stopper may prevent the damper member 151 from continuing to slide in the second straight line direction, so that the damper member 151 maintains the air adjustment state of the air inlet 113 in the natural state.

[0125] like Fig.15 As shown, along the second straight line direction, a driving motor 156 and a transmission arm 157 can be installed between two adjacent damper members 151, and the transmission arm 157 can be connected to the driving motor 156 so that the driving motor 156 can drive the transmission arm 157 to rotate. Fig.15 In the initial position state shown in FIG. 1 , the first end of the transmission arm 157 may not be in contact with the two damper members 151. Under the action of the reset member 155, the two damper members 151 may also be in the initial position state, so that the two corresponding air inlets 113 (such as Fig.10 shown) in the open position.

[0126] Based on this, Fig.16 As shown, the driving motor 156 can also be controlled to drive the transmission arm 157 to rotate clockwise, so that the first end of the transmission arm 157 can approach and push the right damper member 151 to move rightward along the left-right direction until the air inlet 113 (as shown in FIG. Fig.10 Correspondingly, the air door component 151 on the left side can keep the air inlet 113 on the left side open under the action of the reset component 155, so as to facilitate the operation and control of the air adjustment position state of the air door component 15.

[0127] In addition, the driving motor 156 can also drive the transmission arm 157 to rotate counterclockwise, so that the first end of the transmission arm 157 can approach the left damper member 151 in the left-right direction and push the air inlet 113 at the left damper member 151 to move leftward until the air inlet 113 at the left damper member 151 is in the air adjustment position state. Correspondingly, the right damper member 151 can keep the right air inlet 113 in the open state under the action of the reset member 155, so as to facilitate the operation and control of the air adjustment position state of the damper assembly 15.

[0128] For example, the reset member 155 can be a spring, an elastic sheet, an elastic rope, or a rubber column with good compression recovery performance. It is only necessary to adjust the installation method and position of the reset member 155 according to actual needs so that the reset member 155 can act on the damper member 151 and keep it in the initial position state, and the present application does not limit it.

[0129] In the above embodiment, when the damper member 151 is controlled to slide in the left-right direction by the driving motor 156 to adjust the state of the corresponding air inlet 113, the driving motor 156 can be controlled to drive the rotation amplitude of the transmission arm 157 to adjust the movement amplitude of the damper member 151 in the left-right direction, such as making the corresponding air inlet 113 in the air adjustment state with the opening area reduced or closed.

[0130] In addition, if Fig.17 As shown, the damper assembly 15 may further include a drive connection member 158 and a transmission limiter 159. Along the Y direction, the drive connection member 158 may be connected to the oil filter member 16 (such as Fig.16 As shown in the figure, the driving motor 156 can be installed on the side of the driving connecting member 158 away from the oil filter 16 and connected to the driving connecting member 158, and the transmission arm 157 can be installed between the driving connecting member 158 and the oil filter 16 and connected to the output shaft of the driving motor 156 that passes through the driving connecting member 158, so that the driving motor 156 can drive the transmission arm 157 to rotate and adjust the position status of the two damper members 151.

[0131] Continue to refer to Fig.17 The transmission limiter 159 is located on the same side of the driving connector 158 as the transmission arm 157 along the Y direction. The transmission limiter 159 may be two limiter posts, which may be connected to the driving connector 158 and arranged at intervals.

[0132] When the driving motor 156 drives the transmission arm 157 to rotate so that the air inlet 113 at one of the damper members 151 is in the air adjustment state, the transmission arm 157 can contact one of the limiting posts to prevent the transmission arm 157 from continuing to rotate. When the driving motor 156 drives the transmission arm 157 to rotate so that the air inlet 113 at another damper member 151 is in the air adjustment state, the transmission arm 157 can contact another limiting post to prevent the transmission arm 157 from continuing to rotate.

[0133] In the above embodiment, the second end of the transmission arm 157 may be connected to the output shaft of the driving motor 156 , or the middle portion of the transmission arm 157 may be connected to the output shaft of the driving motor 156 .

[0134] If the middle of the transmission arm 157 is connected to the output shaft of the driving motor 156, the installation positions of the two limiting posts can be adjusted so that when the transmission arm 157 rotates clockwise to put one of the air inlets 113 in the air adjustment state, the second end of the transmission arm 157 can contact one of the limiting posts to prevent it from continuing to rotate. Similarly, when the transmission arm 157 rotates counterclockwise to put the other air inlet 113 in the air adjustment state, the second end of the transmission arm 157 can contact the other limiting post to prevent it from continuing to rotate.

[0135] In the above embodiment, the transmission limiter 159 may also be a groove-shaped structure of the driving connector 158, and it is sufficient to limit the transmission arm 157 from continuing to rotate when the air inlet 113 is in the air adjustment state. The output shaft of the driving motor 156 may be directly connected to the transmission arm 157, or the output shaft of the driving motor 156 may be connected to the transmission arm 157 through a transmission gear or a gear box, and this is not limited.

[0136] It should be noted that when controlling the damper member 151 to adjust the opening of the air inlet 113 , there is no need to set the drive motor 156 , that is, the user can manually move the transmission arm 157 to make the corresponding damper member 151 adjust the opening size of the corresponding air inlet 113 .

[0137] Alternatively, the driving motor 156 and the damper member 151 may be arranged in a one-to-one correspondence, for example, one damper member 151 may be provided with a rack extending along the second straight line direction, and one driving motor 156 may be meshed with the rack of one damper member 151 via a gear, and similarly, the damper member 151 may be controlled to adjust the air inlet 113 between the air regulating state and the open state by controlling the forward or reverse rotation of the driving motor 156. This is not limited.

[0138] In some embodiments, Fig.18 As shown, the smoke stove linkage system 100 may further include a controller 30 and an annunciator 40. The controller 30 may be electrically connected to the annunciator 40, the drive motor 156, the exhaust fan 122 and the smoke collecting drive 133.

[0139] Exemplarily, the signaler 40 may include a first signaler and a second signaler, the first signaler is used to detect whether the first stove head 21 is in an ignition state and output a first detection signal, and the second signaler is used to detect whether the second stove head 22 is in an ignition state and output a second detection signal. The controller 30 may be electrically connected to the first signaler and the second signaler, and is used to receive the first detection signal and the second detection signal to determine the ignition state of the first stove head 21 and the second stove head 22.

[0140] In the case where the range hood 10 includes the smoke collecting drive 133 , when the range hood 10 is started, the controller 30 may first control the smoke collecting drive 133 to operate, so as to rotate the smoke collecting plate 131 and open the plurality of air inlets 113 .

[0141] Subsequently, the controller 30 may identify the state of whether the first stove 21 and the second stove 22 are ignited through the first detection signal and the second detection signal. For example, the controller 30 may receive the following signals through the first detection signal and the second detection signal: ① an ignition signal of the first stove 21 and the second stove 22, ② a signal that the first stove 21 and the second stove 22 are not ignited, ③ a signal that the first stove 21 is ignited and the second stove 22 is not ignited, and ④ a signal that the first stove 21 is not ignited and the second stove 22 is ignited.

[0142] For example, when the controller 30 receives the ignition signals of the first stove 21 and the second stove 22, the controller 30 can control the damper assembly 15 to be in the initial position state by driving the motor 156, so that the multiple air inlets 113 can be in the open state. Then, the controller 30 can control the exhaust fan 122 of the fan assembly 12 to start, so as to extract particulate matter such as oil smoke.

[0143] When the controller 30 receives a signal that the first stove 21 is ignited and the second stove 22 is not ignited, the controller 30 can control the damper assembly 15 to be in the air adjustment position state. That is, the controller 30 can drive the damper member 151 through the driving motor 156 to make the air inlet 113 toward the second stove 22 in the air adjustment state, and the corresponding air inlet 113 toward the first stove 21 can be in an open state, so as to quickly extract the oil smoke and other particulate matter at the first stove 21.

[0144] When the controller 30 receives a signal that the second stove 22 is ignited and the first stove 21 is not ignited, the controller 30 can control the damper assembly 15 to be in the air adjustment position state. That is, the controller 30 can drive the damper member 151 through the driving motor 156 to make the air inlet 113 toward the first stove 21 in the air adjustment state, and the corresponding air inlet 113 toward the second stove 22 can be in an open state, so as to quickly extract the oil smoke and other particulate matter at the second stove 22.

[0145] When the controller 30 receives a signal that the first stove 21 and the second stove 22 are not ignited, the controller 30 can control the damper assembly 15 to be in the initial position state by driving the motor 156, so that the multiple air inlets 113 can be in an open state. At the same time, the controller 30 can control the exhaust fan 122 of the fan assembly 12 to stop rotating (or delay stopping), and finally the controller 30 can control the smoke collecting drive 133 to make the smoke collecting plate 131 close the multiple air inlets 113.

[0146] It should be noted that when the first stove 21 and the second stove 22 are ignited and the air door assembly 15 is in the initial position, the controller 30 can use the stir-fry gear signal to put the air inlet 113 at the first stove 21 or the second stove 22 in the air adjustment state. That is, the stir-fry gear signal can have a higher priority.

[0147] Exemplarily, the first signaler and the second signaler may be position sensors, such as a position sensor may be installed at the knob of the cooker 20 to detect the gear position of the knob, thereby determining whether the corresponding cooker head is in the ignition state. If the cooker 20 and the range hood 10 are separate structures, the first signaler and the second signaler may be connected to the controller 30 via wireless signals; if the cooker 20 and the range hood 10 are integrated structures, the first signaler and the second signaler may also be connected to the controller 30 via wired signals.

[0148] In addition, the first signal device and the second signal device may also be infrared sensors or temperature sensors, and the first signal device may be installed corresponding to the first stove head 21, and the second signal device may be installed corresponding to the second stove head 22. Then, the infrared signal or the temperature signal may be used to determine whether the first stove head 21 and the second stove head 22 are in the ignition state.

[0149] In the above embodiment, the controller 30 and the signaler 40 can be used as a part of the range hood 10, such as the controller 30 can be integrated into the electrical box 14 of the range hood 10, and the first signaler and the second signaler of the position sensor can be accessories of the range hood 10, such as stove knob accessories. When in use, the knob of the stove 20 under the range hood 10 can be replaced to achieve the modification of the range hood and stove linkage system 100, which is not limited to this.

[0150] On the other hand, the embodiment of the present application further provides a control method of a smoke-stove linkage system, which is used to control the smoke-stove linkage system 100 in the above aspect. The control method may include:

[0151] When the ignition signals of the first stove and the second stove are received or the ignition signals of the first stove and the second stove are not received, the wind assembly is controlled to be in an initial position state so that the multiple air inlets are in an open state.

[0152] When an ignition signal from the first stove is received but an ignition signal from the second stove is not received, the damper member is controlled to place the air inlet toward the second stove in an air adjustment state and place the air inlet toward the first stove in an open state.

[0153] When an ignition signal from the second stove is received but an ignition signal from the first stove is not received, the damper member is controlled to place the air inlet toward the first stove in an air-adjusting state and place the air inlet toward the second stove in an open state.

[0154] Based on this, Fig.19 As shown, in the process of controlling the operation of the range hood linkage system, after the start step (i.e. the system is in a standby state), it is necessary to detect whether the first burner and the second burner of the cooker are in an ignition state through the first determination step. If the first burner and the second burner are in an unignited state, the damper assembly can be controlled to maintain the initial position state so that the two air inlets are in an open state, and the fan assembly can stop rotating (i.e. the range hood is in an unstarted state), and then the system can return to the start step to continue to execute the first determination step.

[0155] Reference Fig.19 If the first burner and / or the second burner in the first determination step are in the ignition state, the second determination step can be entered to detect whether only the first burner is ignited. If the first burner is ignited and the second burner is not ignited, the damper assembly can be controlled to open the air inlet toward the first burner and adjust the air inlet toward the second burner (the opening is reduced or closed), so that the range hood can quickly and centrally extract the oil smoke and other particles above the first burner, and then the first determination step can be returned to continue to be executed to monitor the ignition state of the cooker in real time.

[0156] Continue to refer to Fig.19 In the second determination step, if the first stove is not ignited and the second stove is ignited, or the first stove and the second stove are both ignited, the third determination step can be entered to detect whether only the second stove is ignited. If the first stove is not ignited and the second stove is ignited, the damper assembly can be controlled to open the air inlet toward the second stove, and to adjust the air inlet toward the first stove (the opening is reduced or closed), so that the range hood can quickly and centrally extract the oil smoke and other particulate matter above the second stove, and then the first determination step can be returned to continue to monitor the ignition status of the stove in real time.

[0157] like Fig.19 As shown, in the third determination step, if both the first stove and the second stove are ignited, the damper assembly can be controlled to be in the initial position state so that both air outlets are in the open state. At this time, the range hood can simultaneously extract the oil smoke and other particles above the first stove and the second stove, and then return to continue to execute the first determination step to monitor the ignition state of the stove in real time.

[0158] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0159] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
