[0065] Embodiment 1

[0066] like Figure 1As shown, the embodiment of the present disclosure provides an oil fume treatment device 100, which can be all types of devices with oil fume treatment function, such as a ceiling-mounted range hood, a side-suction range hood, a top-suction range hood, etc. All types of devices with oil fume treatment function are within the protection scope of the embodiment of the present disclosure. The embodiment of the present disclosure takes the ceiling-mounted range hood as an example to illustrate the structure of the oil fume treatment device 100.

[0067] like Figure 1 to Figure 3 As shown, the oil fume treatment device 100 includes a fan assembly 20, a smoke collection system 10 and a pipeline assembly 30. The fan assembly 20 includes a chassis body 21. One end of the pipeline assembly 30 is connected to the chassis body 21, and the other end of the pipeline assembly 30 is connected to the smoke collection system 10. Figure 1 and Figure 2 As shown, the fan assembly 20 also includes a main fan 22, which is arranged inside the chassis body 21. The main fan 22 can generate negative pressure, which can make the oil smoke in the cooking area 400 pass through the smoke collection system 10, the pipeline assembly 30 and the chassis body 21 in sequence and then be discharged to the outside.

[0068] like Figure 1 As shown, the chassis body 21 is arranged above the ceiling 300, and the chassis body 21 is detachably connected to the top wall 200. The chassis body 21 is arranged above the ceiling 300, which is far away from the user. The ceiling 300 can isolate the noise during the operation of the chassis body 21, reduce the impact of the noise on the user, and improve the user experience. When the height of the wall 200 is different, the working reliability of the oil fume treatment device 100 is ensured by adjusting the length of the pipeline assembly 30.

[0069] like Figure 1 As shown, the smoke collecting system 10 includes a smoke collecting chamber 11 and a flap 12 , wherein the smoke collecting chamber 11 is provided with a smoke inlet 111 , the flap 12 is arranged on the smoke collecting chamber 11 , and the flap 12 can switch between a first state of opening the smoke inlet 111 and a second state of closing the smoke inlet 111 .

[0070] In modern kitchen design, the air supply system is a key component to ensure indoor air quality and environmental comfort. The role of the air supply system is to provide fresh air to the kitchen to balance the air exhausted due to the fumes and heat generated during the cooking process. The lack of an air supply system will bring a series of negative effects, including reduced air quality, negative pressure problems, difficulty in controlling temperature and humidity, increased safety risks, and reduced system efficiency. These problems not only affect the health and work efficiency of kitchen staff, but may also pose a threat to the normal operation and safe use of kitchen equipment.

[0071] The existing air supply system and the oil fume treatment device are independently arranged. The overall structure of the air supply system and the oil fume treatment device is complex, large in size and occupies a large space, which is not conducive to the rational use of the kitchen space.

[0072] To solve the above problems, Figure 2 to Figure 5 As shown, an air outlet 312 is provided on the pipeline assembly 30 of the oil fume treatment device 100 in the embodiment of the present disclosure, and the oil fume treatment device 100 also includes an oil fume separation system 40, which is arranged inside the pipeline assembly 30, and the oil fume separation system 40 has an oil fume inlet 411, an air outlet 422 and an oil fume exhaust end 423 arranged along the flow direction of the oil fume, the air outlet 422 is connected with the air outlet 312, and the oil fume exhaust end 423 is connected with the fan assembly 20. The oil smoke entering from the smoke inlet 111 and the oil smoke inlet 411 is separated into clean air and the oil smoke mixture through the oil smoke separation system 40. The oil smoke mixture enters the fan assembly 20 through the oil smoke exhaust end 423. The separated clean air is discharged into the kitchen through the air outlet 422 and the air outlet 312 in turn, thereby providing fresh air to the kitchen to balance the air inside the kitchen discharged due to the oil smoke and heat generated during the cooking process, thereby ensuring the health and work efficiency of the kitchen staff and the normal operation of the kitchen equipment.

[0073] In addition, the oil fume treatment device also includes an environmental status detection mechanism, which is used to detect environmental status information of the environment. The fan assembly 20 and the oil fume separation system 40 can adjust their own working states according to the environmental status information detected by the environmental status detection mechanism to make the air pressure of the environment adaptively balanced. It can achieve adaptive balance of the air pressure of the environment when the oil fume treatment device 100 is operating under different working conditions, and can ensure that the oil fume separation system 40 provides fresh air to the interior of the kitchen to balance the air inside the kitchen discharged due to the oil fume and heat generated during the cooking process, thereby ensuring the health and work efficiency of kitchen staff and ensuring the normal operation of kitchen equipment.

[0074] The environmental state detection mechanism may include an oil fume concentration detection mechanism, which is used to detect oil fume physical property information of the oil fume. 检测 , among which, the oil smoke physical property information J 检测 It can include oil fume concentration information, oil fume flow information, oil fume temperature information, etc. All oil fume physical property information that can reflect the oil fume situation 检测 All of them are within the protection scope of the embodiments of the present disclosure.

[0075] Among them, the environmental status detection mechanism may also include an air pressure detection mechanism, which is used to detect the ambient air pressure information of the environment, wherein the ambient air pressure information may include the ambient air pressure value, the ambient air pressure change value, etc. All information that can reflect the ambient air pressure conditions is within the protection scope of the present disclosed embodiment.

[0076] like Figure 2 to Figure 5 As shown, the distance between the fan assembly 20 and the smoke collection system 10 is relatively far, the length of the pipe assembly 30 is long, and there is a large unused space inside the pipe assembly 30. The oil fume treatment device 100 of the disclosed embodiment sets the oil fume separation system 40 in the pipe assembly 30, and can reasonably utilize the internal space of the pipe assembly 30 to add the oil fume separation system 40 to achieve air replenishment inside the kitchen. There is no need to add an additional air replenishment system outside the oil fume treatment device 100, and no extra space will be wasted.

[0077] In summary, the oil fume treatment device 100 with air supply function of the embodiment of the present disclosure has a simple overall structure, a small size and occupies a small space, can realize the rational use of kitchen space, and can effectively improve the user experience.

[0078] Specifically, if Figure 2 to Figure 5 As shown, the oil fume separation system 40 of the embodiment of the present disclosure includes an auxiliary fan 41 and an oil fume filtering mechanism 42 arranged along the flow direction of the oil fume, the auxiliary fan 41 has an oil fume inlet 411, and the oil fume filtering mechanism 42 has an air inlet 421, an air outlet 422 and an oil fume discharge end 423, and the air inlet 421 is located downstream of the auxiliary fan 41 and communicates with the air outlet 422. The oil fume entering from the smoke inlet 111 and the oil fume inlet 411 is initially separated under the centrifugal action of the auxiliary fan 41. Due to the different densities of the air and oil fume mixture, as shown in FIG. Figure 4As shown, the centrifugal action of the auxiliary fan 41 separates the oil fume into an air core M of air and an airflow N of an oil fume mixture, wherein the air core M of air is located in the central area, and the airflow N of the oil fume mixture surrounds the periphery of the air core M of air, and the air core M of air passes through the air inlet 421, the air outlet 422 and the air outlet 312 in sequence, thereby being discharged to the inside of the kitchen. The airflow N of the oil fume mixture moves along the periphery of the oil fume filter mechanism 42, and the oil fume mixture finally flows into the fan assembly 20 at the oil fume discharge end 423 for the final oil fume separation. Through the combination of the auxiliary fan 41 and the oil fume filter mechanism 42, a better separation effect for oil fume can be achieved, and a large amount of clean air can be formed. The oil fume treatment device 100 can provide a large amount of fresh air to the inside of the kitchen to balance the air inside the kitchen discharged due to the oil fume and heat generated during the cooking process, ensure the health and work efficiency of the kitchen staff, and ensure the normal operation of the kitchen equipment. In addition, by providing the auxiliary fan 41 , the oil fume absorbing effect of the oil fume treatment device 100 can be effectively improved, and the oil fume treatment device 100 can achieve a better oil fume absorption effect.

[0079] In an optional embodiment, the oil fume separation system may also only include an oil fume filtering mechanism. The oil fume separation system of this structure has a simple structure and occupies a small space.

[0080] In an optional embodiment, the oil fume separation system may also be a cyclone separator, which can also achieve a good separation effect of the oil fume mixture and air.

[0081] like Figure 2 to Figure 5 As shown, the oil fume filtering mechanism 42 is a conical cyclone tube, and the cross-sectional area of ​​the conical cyclone tube gradually increases along the flow direction of the oil fume. The conical cyclone tube is a reducer tube, and the outer shape of the conical cyclone tube is conical. The reducer tube can be used to enable the end with a smaller diameter to generate a stronger negative pressure. The end with a smaller diameter of the conical cyclone tube is used to inhale the air core M of the air, so that a strong negative pressure area can be formed above the auxiliary fan 41. The negative pressure area has good suction capacity and can effectively and quickly inhale the air core M of the air in a gathered state, thereby preventing the air core M of the air from spreading to the surroundings, and a large amount of clean gas can be discharged from the air outlet 312.

[0082] like Figure 4As shown, the separated air core M rises in a spiral shape, and the air core M of the air is cone-shaped as a whole. The cross-sectional area of ​​the cone gradually decreases along the flow direction of the oil fume. When the rotation speed of the auxiliary fan 41 increases, the centrifugal force of the auxiliary fan 41 on the oil fume is greater, and the cross-sectional area of ​​the air core M of the air increases as a whole. Therefore, if the distance between the auxiliary fan 41 and the oil fume filtering mechanism 42 is fixed, the cross-sectional area of ​​the air core M at the air inlet 421 is larger than the cross-sectional area of ​​the air inlet 421, and a part of the clean air cannot enter the air inlet 421, resulting in a waste of clean air.

[0083] In order to solve the above problems, Figure 4 , Figure 5 and Figure 7 As shown, the distance between the auxiliary fan 41 and the oil fume filtering mechanism 42 is adjustable. When the rotation speed of the auxiliary fan 41 increases, the distance between the auxiliary fan 41 and the oil fume filtering mechanism 42 can be increased, so that the cross-sectional area of ​​the air core M of the newly formed air at the air inlet 421 is equal to the cross-sectional area of ​​the air inlet 421, thereby achieving the maximum utilization rate of the clean air formed and realizing a better air replenishment effect of the oil fume treatment device 100 on the inside of the kitchen.

[0084] like Figures 4 to 6 As shown, the pipeline assembly 30 includes a pipeline assembly body 31 and a partition assembly 32. One end of the pipeline assembly body 31 is connected to the fan assembly 20, and the other end of the pipeline assembly body 31 is connected to the smoke collection system 10. The partition assembly 32 is arranged inside the pipeline assembly body 31. The partition assembly 32 divides the interior of the pipeline assembly body 31 into at least two channels 311. Each channel 311 is provided with a corresponding group of oil fume separation systems 40. Each group of oil fume separation systems 40 can independently control the corresponding channel 311 separately. The oil fume treatment device 100 can adjust the working state of each group of oil fume separation systems 40 according to the oil fume situation inside the kitchen, so that the oil fume treatment device 100 can match different oil fume situations, and can ensure that the oil fume treatment device 100 always has a good absorption effect on different oil fume situations.

[0085] For example, Figure 3 , Figure 5 and Figure 6 As shown, the partition assembly 32 includes a plurality of partitions 321 , and the plurality of partitions 321 are arranged at intervals along the width direction of the pipeline assembly 30 to form a plurality of independent channels 311 .

[0086] like Figure 6As shown, the minimum spacing between the outer peripheral surface of the auxiliary fan 41 and the inner wall of the channel 311 is 3 mm to 5 mm. On the one hand, the interference between the auxiliary fan 41 and the inner wall of the channel 311 can be avoided when the auxiliary fan 41 is working, and the normal operation of the auxiliary fan 41 is ensured. On the other hand, the setting of the minimum spacing is moderate, which can avoid the leakage and reverse overflow of the oil smoke in the channel 311. The space of the channel 311 is small, and the negative pressure formed by the channel 311 is more concentrated, which can achieve a better absorption effect of the channel 311 on the oil smoke.

[0087] like Figure 6 As shown, the cross-section of the channel 311 is a square, and the center line of the channel 311, the first axis of the auxiliary fan 41 and the second axis of the oil fume filtering mechanism 42 are coaxially arranged. Through the design of this structure, the waste of the internal space of the pipeline assembly body 31 can be avoided, and the maximum utilization rate of the internal space of the pipeline assembly body 31 can be achieved.

[0088] like Figure 6 As shown, if the auxiliary fans 41 in two adjacent channels 311 have the same rotation direction, the oil fumes in the two channels 311 will collide at the connection position of the oil fume outlets of the two adjacent channels 311. On the one hand, the exhaust speed of the oil fume is reduced, affecting the smooth flow of the oil fume to the fan assembly 20; on the other hand, it will also generate greater noise.

[0089] In order to solve the above problems, Figure 6 As shown, the auxiliary fans 41 in two adjacent channels 311 rotate in opposite directions, so there will be no collision of the oil fumes in the two channels 311 at the connection position of the oil fume outlets of the two adjacent channels 311, the oil fume at the connection position of the oil fume outlets of the two channels 311 is better mixed, and the oil fume is discharged faster, ensuring that the oil fume always flows smoothly to the fan assembly 20, avoiding excessive noise emitted by the oil fume treatment device 100 during use, and achieving the silent use effect of the oil fume treatment device 100.

[0090] like Figure 6 and Figure 7 As shown, the pipeline assembly 30 also includes an air outlet pipe 33, which is connected to the air outlet 422. The air outlet pipe 33 can make the clean air flowing out of the air outlet 422 diffuse better into the kitchen room.

[0091] like Figure 6 and Figure 7As shown, along the air flow direction, the cross-sectional area of ​​the air outlet duct 33 tends to increase, which can further improve the diffusion of the clean air flowing out of the air outlet 422 into the kitchen. Exemplarily, the cross-sectional shape of the air outlet duct 33 can be rectangular, circular, elliptical, etc., and all types of cross-sectional shapes of the air outlet duct 33 are within the protection scope of the embodiments of the present disclosure.

[0132] S222': Control the auxiliary fan to the first auxiliary speed V 辅助1 Running and in first position L 1 ;

[0133] Among them, in S221', if △P 1 <△P 预设1 , it means that the ambient air pressure change in this scenario is not drastic enough. Even if the auxiliary fan 41 does not work, it can still meet the basic air pressure requirements of the environment. Therefore, it is possible to return to obtain the first ambient air pressure change information △P 1 Step, continuously for the first ambient air pressure change information △P 1 Conduct detection and judgment.

[0134] Among them, in S221', if △P 1 ≥△P 预设1 , it means that the ambient air pressure changes relatively drastically in this scenario, so it is necessary to further perform S222', thereby starting the auxiliary fan 41 to increase the discharge of clean air to balance the air inside the kitchen discharged due to the fumes and heat generated during the cooking process, so as to meet the basic air pressure requirements for the environment, ensure the health and work efficiency of the kitchen staff, and ensure the normal operation of the kitchen equipment.

[0135] In S222', in different usage scenarios of the oil fume treatment device 100, since the air pressure drop in the environment in this scenario is relatively low, the first auxiliary speed V can be controlled. 辅助1 Running, first auxiliary speed V 辅助1 is relatively small, through a relatively small first auxiliary speed V 辅助1 It will be able to balance the air inside the kitchen discharged due to the fumes and heat generated during the cooking process in this scenario, so as to meet the basic air pressure requirements of the environment, ensure the health and work efficiency of the kitchen staff, and ensure the normal operation of the kitchen equipment.

[0136] like Figure 4 As shown, due to the first auxiliary speed V 辅助1 The centrifugal force of the auxiliary fan 41 on the oil smoke is relatively small, and the resulting Figure 4 The cross section of the air core M shown is relatively small as a whole, so the auxiliary fan 41 is at a relatively high position. 1 , it is possible to ensure that all the separated air cores M enter the air inlet 421, thus avoiding the waste of clean air.

[0137] Exemplarily, the first auxiliary speed V 辅助1 It can be 600r / min. When the auxiliary fan 41 is in the first position L 1 When Figure 1 , Figure 4 and Figure 5As shown, the distance between the lowermost end of the auxiliary fan 41 and the cooking area 400 is 400 mm.

[0145] If △P 1 <△P 预设2 , then return to S212'';

[0146] Among them, in S221'', if △P 1 <△P 预设2 , it means that the ambient air pressure change in this scenario is not drastic enough. Even if the auxiliary fan 41 does not work, it can still meet the basic air pressure requirements of the environment. Therefore, it is possible to return to obtain the first ambient air pressure change information △P 1 Step, continuously for the first ambient air pressure change information △P 1 Conduct detection and judgment.

[0147] If △P 1 ≥△P 预设2 , then proceed to S222'';

[0148] Among them, in S221'', if △P 1 ≥△P 预设2, it means that the ambient air pressure changes relatively drastically in this scenario, so it is necessary to further perform subsequent S222'', S223'' and S224'', so as to realize the operation of the auxiliary fan 41 and increase the discharge of clean air to balance the air inside the kitchen discharged due to the fumes and heat generated during the cooking process, so as to meet the basic air pressure requirements for the environment, ensure the health and work efficiency of the kitchen staff, and ensure the normal operation of the kitchen equipment.

[0149] Specifically, S222'': obtaining the second oil fume physical property information J in each channel 311 检测2 ;

[0150] S223'': Based on the second oil smoke physical property information J in each channel 检测2 , dividing at least two channels into main smoke inlet channels or auxiliary smoke inlet channels;

[0151] S224'': Control the auxiliary fan in the main smoke inlet channel to rotate at the second auxiliary speed V 辅助2 Running and in first position L 1 , control the auxiliary fan in the auxiliary smoke inlet channel to the third auxiliary speed V 辅助3 Running and in the second position L 2 , where V 辅助1 <V 辅助2 <V 辅助3 , L 1 >L 2 ;

[0152] When J 1 ≤J 检测1 <J 2 When the concentration of oil smoke is relatively moderate, the fan assembly 20 is controlled to rotate at a second fan speed N with a moderate rotation speed. 2 Operation can achieve a better absorption effect on moderate concentration of oil smoke. The ambient air pressure drop in this scenario will be greater than that in the previous scenario (when J 检测1 <J 1 The ambient pressure drops more dramatically at the first auxiliary speed V 辅助1 The auxiliary fan 41 is running at the second auxiliary speed V 辅助2 Or the third auxiliary speed V 辅助3 Operation can produce more clean air to balance the air inside the kitchen discharged due to the fumes and heat generated during the cooking process in this scenario, so as to meet the basic air pressure requirements for the environment, ensure the health and work efficiency of kitchen staff, and ensure the normal operation of kitchen equipment.

[0153] In S223'', the second oil smoke physical property information J 检测2The larger channel 311 is identified as the main smoke inlet channel, which can pass a relatively large amount of oil smoke, but a relatively small amount of clean air. 检测2 The smaller channel 311 is identified as an auxiliary smoke inlet channel, which can pass a relatively large amount of clean air and a relatively small amount of oil smoke. By setting the main smoke inlet channel and the auxiliary smoke inlet channel, the air pressure in the environment when the oil fume treatment device 100 is running under different working conditions can be adaptively balanced.

[0154] Specifically, the second oil smoke physical property information J 检测2 It can be oil fume temperature, oil fume concentration, oil fume flow rate, etc. All parameters that can reflect the proportion of oil fume are included in the second oil fume physical property information J 检测2 within the scope of protection.

[0155] In step S223'', the second oil fume physical property information J in each channel 311 is used. 检测2 , dividing at least two channels 311 into main smoke inlet channels or auxiliary smoke inlet channels, specifically, the second oil smoke physical property information J 检测2 and the third preset value J of oil smoke physical property information 3 For comparison: If J 检测2 ≥J 3 , it means that the oil smoke concentration inside the channel 311 is relatively high, and the channel 311 can be set as the main smoke inlet channel, which mainly passes the oil smoke; if J 检测2 <J 3 , it means that the oil smoke concentration inside the channel 311 is relatively small, and the channel 311 can be set as an auxiliary smoke inlet channel, which mainly passes clean air.

[0156] In S224'', the auxiliary fan 41 in the main smoke inlet channel is controlled to rotate at a second auxiliary speed V 辅助2 The auxiliary fan 41 in the auxiliary smoke inlet channel is controlled to run at a third auxiliary speed V 辅助3 Run, where V 辅助2 <V 辅助3 The auxiliary fan 41 in the auxiliary smoke inlet channel has a greater centrifugal force on the oil smoke, and forms more clean air, so that more clean air passes through the auxiliary smoke inlet channel. The auxiliary fan 41 in the main smoke inlet channel has a relatively small centrifugal force on the oil smoke, and forms less clean air, so that more oil smoke passes through the main smoke inlet channel. By adjusting the rotation speed of the auxiliary fan 41, the channel 311 can be quickly switched between the main smoke inlet channel and the auxiliary smoke inlet channel.

[0157] like Figure 4As shown, the separated air core M rises in a spiral shape, and the air core M of the air is cone-shaped as a whole. The cross-sectional area of ​​the cone gradually decreases along the flow direction of the oil fume. When the rotation speed of the auxiliary fan 41 increases, the centrifugal force of the auxiliary fan 41 on the oil fume is greater, and the cross-sectional area of ​​the air core M of the air increases as a whole. Therefore, if the distance between the auxiliary fan 41 and the oil fume filtering mechanism 42 is fixed, the cross-sectional area of ​​the air core M at the air inlet 421 is larger than the cross-sectional area of ​​the air inlet 421, and a part of the clean air cannot enter the air inlet 421, resulting in a waste of clean air.

[0158] Therefore, in S224'', due to the third auxiliary speed V 辅助3 Than the second assist speed V 辅助2 The air core M of the air formed in the auxiliary smoke inlet channel is larger than the air core M of the air in the main smoke inlet channel. Therefore, the auxiliary fan 41 in the auxiliary smoke inlet channel needs to be adjusted to a position farther from the air inlet 421. Therefore, the auxiliary fan 41 in the main smoke inlet channel is controlled to be in the first position L. 1 , control the auxiliary fan 41 in the auxiliary smoke inlet channel to be in the second position L 2 , L 1 >L 2 , thereby ensuring that the air core M formed in the auxiliary smoke inlet channel can completely enter the corresponding air inlet 421.

[0159] Exemplarily, the second auxiliary speed V 辅助2 Can be 1200r / min; the third auxiliary speed V 辅助3 It can be 1400r / min; when the auxiliary fan 41 is in the first position L 1 When Figure 1 , Figure 4 and Figure 5 As shown, the distance between the lower end of the auxiliary fan 41 and the cooking area 400 is 400 mm; when the auxiliary fan 41 is in the second position L 2 When Figure 1 and Figure 4 As shown, the distance between the lowermost end of the auxiliary fan 41 and the cooking area 400 is 300 mm.

[0163] If △P 1 <△P 预设3 , then return to S212''';

[0164] Among them, in S221''', if △P 1 <△P 预设3 , it means that the ambient air pressure change in this scenario is not drastic enough. Even if the auxiliary fan 41 does not work, it can still meet the basic air pressure requirements of the environment. Therefore, it is possible to return to obtain the first ambient air pressure change information △P 1 Step, continuously for the first ambient air pressure change information △P 1 Conduct detection and judgment.

[0165] If △P 1 ≥△P 预设3 , then proceed to S222'';

[0166] Among them, in S221''', if △P 1 ≥△P 预设3 , it means that the ambient air pressure changes relatively drastically in this scenario, so it is necessary to further perform subsequent S222'''', S223''''' and S224'''', so as to realize the operation of the auxiliary fan 41 and increase the exhaust of clean air to balance the air inside the kitchen exhausted due to the fumes and heat generated during the cooking process, so as to meet the basic air pressure requirements for the environment, ensure the health and work efficiency of the kitchen staff, and ensure the normal operation of the kitchen equipment.

[0167] Specifically, S222''': obtaining the second oil smoke physical property information J in each channel 检测2 ;

[0168] S223''': Based on the second oil smoke physical property information J in each channel 检测2 , dividing at least two channels 311 into main smoke inlet channels or auxiliary smoke inlet channels;

[0169] S224''': Control the auxiliary fan 41 in the main smoke inlet channel to rotate at a fourth auxiliary speed V 辅助4 Running and in first position L 1 , control the auxiliary fan 41 in the auxiliary smoke inlet channel to rotate at the fifth auxiliary speed V 辅助5 Running and in the second position L 2 , where V 辅助3 <V 辅助4 <V 辅助5 , L1 >L 2 ;

[0170] When J 2 ≤J 检测1 When the concentration of oil smoke is relatively large, the fan assembly 20 is controlled to rotate at a third fan speed N with a larger rotation speed. 3 Operation can achieve a better absorption effect on high-concentration oil smoke. The ambient air pressure drop in this scenario will be greater than that in the previous scenario (when J 1 ≤J 检测1 <J 2 The ambient air pressure drops more dramatically, so the auxiliary fan 41 is driven at the fourth auxiliary speed V 辅助4 Or the fifth auxiliary speed V 辅助5 Running compared to the third auxiliary speed V 辅助3 It can produce more clean air to balance the air inside the kitchen discharged due to the fumes and heat generated during the cooking process in this scenario, so as to meet the basic air pressure requirements for the environment, ensure the health and work efficiency of kitchen staff, and ensure the normal operation of kitchen equipment.

[0171] In S223''', the second oil smoke physical property information J 检测2 The larger channel 311 is identified as the main smoke inlet channel, which can pass a relatively large amount of oil smoke, but a relatively small amount of clean air. 检测2 The smaller channel 311 is identified as an auxiliary smoke inlet channel, which can pass a relatively large amount of clean air and a relatively small amount of oil smoke. By setting the main smoke inlet channel and the auxiliary smoke inlet channel, the air pressure in the environment when the oil fume treatment device 100 is running under different working conditions can be adaptively balanced.

[0172] Specifically, the second oil smoke physical property information J 检测2 It can be oil fume temperature, oil fume concentration, oil fume flow rate, etc. All parameters that can reflect the proportion of oil fume are included in the second oil fume physical property information J 检测2 within the scope of protection.

[0173] In step S223, the second oil fume physical property information J in each channel 311 is used. 检测2 , dividing at least two channels 311 into main smoke inlet channels or auxiliary smoke inlet channels, specifically, the second oil smoke physical property information J 检测2 and the fourth preset value J of oil smoke physical property information 4 For comparison: If J 检测2 ≥J 4, it means that the oil smoke concentration inside the channel 311 is relatively high, and the channel 311 can be set as the main smoke inlet channel, which mainly passes the oil smoke; if J 检测2 <J 4 , it means that the oil smoke concentration inside the channel 311 is relatively small, and the channel 311 can be set as an auxiliary smoke inlet channel, which mainly passes clean air.

[0174] In S224''', the auxiliary fan 41 in the main smoke inlet channel is controlled to rotate at a fourth auxiliary speed V 辅助4 The auxiliary fan 41 in the auxiliary smoke inlet channel is controlled to run at a fifth auxiliary speed V 辅助5 Run, where V 辅助4 <V 辅助5 The auxiliary fan 41 in the auxiliary smoke inlet channel has a greater centrifugal force on the oil smoke, and forms more clean air, so that more clean air passes through the auxiliary smoke inlet channel. The auxiliary fan 41 in the main smoke inlet channel has a relatively small centrifugal force on the oil smoke, and forms less clean air, so that more oil smoke passes through the main smoke inlet channel. By adjusting the rotation speed of the auxiliary fan 41, the channel 311 can be quickly switched between the main smoke inlet channel and the auxiliary smoke inlet channel.

[0175] like Figure 4 As shown, the separated air core M rises in a spiral shape, and the air core M of the air is cone-shaped as a whole. The cross-sectional area of ​​the cone gradually decreases along the flow direction of the oil fume. When the rotation speed of the auxiliary fan 41 increases, the centrifugal force of the auxiliary fan 41 on the oil fume is greater, and the cross-sectional area of ​​the air core M of the air increases as a whole. Therefore, if the distance between the auxiliary fan 41 and the oil fume filtering mechanism 42 is fixed, the cross-sectional area of ​​the air core M at the air inlet 421 is larger than the cross-sectional area of ​​the air inlet 421, and a part of the clean air cannot enter the air inlet 421, resulting in a waste of clean air.

[0176] Therefore, in S224''', since the third auxiliary speed V 辅助3 Than the second assist speed V 辅助2 The air core M of the air formed in the auxiliary smoke inlet channel is larger than the air core M of the air in the main smoke inlet channel. Therefore, the auxiliary fan 41 in the auxiliary smoke inlet channel needs to be adjusted to a position farther from the air inlet 421. Therefore, the auxiliary fan 41 in the main smoke inlet channel is controlled to be in the first position L. 1 , control the auxiliary fan 41 in the auxiliary smoke inlet channel to be in the second position L 2 , L 1 >L 2 , thereby ensuring that the air core M formed in the auxiliary smoke inlet channel can completely enter the corresponding air inlet 421.

[0177] Exemplarily, the fourth auxiliary speed V 辅助4 Can be 1600r / min; fifth auxiliary speed V 辅助5 It can be 1800r / min; when the auxiliary fan 41 is in the first position L 1 When Figure 1 , Figure 4 and Figure 5 As shown, the distance between the lower end of the auxiliary fan 41 and the cooking area 400 is 400 mm; when the auxiliary fan 41 is in the second position L 2 When Figure 1 and Figure 4 As shown, the distance between the lowermost end of the auxiliary fan 41 and the cooking area 400 is 300 mm.

[0186] S242: Control the fan assembly to reduce the speed and control the auxiliary fan to increase the speed;

[0187] When the third oil smoke physical property information J 检测3When the second preset condition is not met, it means that the oil fume separation system 40 is not replenishing enough clean air for the environment, so the discharge amount of clean air needs to be increased. Therefore, the fan assembly 20 is controlled to reduce the speed to reduce the consumption of air in the environment, and at the same time, the auxiliary fan 41 is controlled to increase the speed to increase the production of clean air by the oil fume separation system 40, thereby achieving a rapid increase in the amount of clean air replenished in the environment.

[0188] For example, the third oil smoke physical property information J 检测3 The gas flow rate Q of the air outlet 312 can be 1 The gas flow Q at the smoke inlet 111 2 The ratio of J 检测3 =Q 1 / Q 2 The second preset condition is: judging the third oil fume physical property information J 检测3 Is it greater than or equal to the fourth preset value J of oil fume physical property information? 4 Since the gas flow rate Q 1 The gas flow Q at the smoke inlet 111 2 The ratio is accurate real-time detection information, and the third oil smoke physical property information J 检测3 There will be no lag in the detection results, and the exhaust volume of clean air can be adjusted instantly, efficiently and quickly through the aforementioned adjustment method.

[0189] S25: Acquire second ambient air pressure information of the environment;

[0190] S261: Determine whether the second ambient air pressure information meets the third preset condition: if not, proceed to S262; if yes, proceed to S31;

[0191] S262: Control the auxiliary fan to increase the speed until the second ambient air pressure information meets the third preset condition.

[0192] S25, S261 and S262 use the final result of the ambient air pressure as the adjustment guide, and can be used for Figure 3 The oil fume separation system 40 shown in the figure can further dynamically adjust the working state to make the adaptive balance of the environmental air pressure more accurate, so as to achieve the adaptive balance of the environmental air pressure when the oil fume treatment device 100 is operating under different working conditions, and can ensure that the oil fume separation system 40 provides fresh air to the inside of the kitchen to balance the air inside the kitchen discharged due to the oil fume and heat generated during the cooking process, thereby ensuring the health and work efficiency of the kitchen staff and the normal operation of the kitchen equipment.

[0193] Through the adjustment method of S23 to S262, it is possible to achieve a gradual adjustment to increase the clean air discharge volume without causing excessive changes in the ambient air pressure and the oil fume absorption effect during the overall process.

[0194] S31: Obtaining the fourth oil smoke physical property information J of the cooking area 检测4 ;
