DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0030] See also Figure 1-Figure 3The embodiment of the present application provides a range hood 1, which includes a range hood body 10 and a smoke collecting body 20. The range hood body 10 includes a fan assembly 11 and a flue assembly 12, and the smoke collecting body 20 is connected to the flue assembly 12. It can be understood that a stove is usually arranged below the range hood 1, one end of the flue assembly 12 is connected to the fan assembly 11, and the other end of the flue assembly 12 is connected to the smoke collecting body 20, and the smoke collecting body 20 is arranged on a side of the range hood body 10 close to the stove.

[0031] The fan assembly 11 includes a fan box 111 and a fan 112 accommodated in the fan box 111, that is, the fan box 111 has a fan cavity 111A, and the fan 112 is arranged in the fan cavity 111A. Among them, the fan 112 includes a motor and a wind wheel connected to the output shaft of the motor. The motor can adopt a fully enclosed single-phase capacitor-operated asynchronous motor, and the wind wheel can be a centrifugal wind wheel. When the motor drives the wind wheel to rotate, a negative pressure area is formed in the fan cavity 111A, that is, the internal air pressure of the fan cavity 111A is lower than the air pressure of the external environment, so that the oil smoke can enter the fan assembly 11 through the smoke collecting body 20 and the flue assembly 12 in turn, and be discharged to the outside through the smoke exhaust pipe (not shown in the figure). It can be understood that in the process of exhausting smoke, in order to prevent the backflow of oil smoke, the range hood 1 is usually equipped with a check valve 14.

[0032] It is understandable that the fan box 111 is usually made of metal. For example, the fan box 111 is generally made of A3 cold-rolled steel plate (or stainless steel plate) by stamping and welding, and the surface is treated with phosphating and spraying, so as to reduce the probability of rusting of the fan box 111, so that the fan box 111 can better protect the motor and the wind wheel, reduce the probability of damage to the motor and the wind wheel, and thus make the range hood 1 have a longer service life. After the surface of the fan box 111 is treated with phosphating and spraying, the fan box 111 can be smooth and easy to clean.

[0033] The range hood body 10 has a smoke exhaust passage 12A. It is understandable that the smoke duct assembly 12 is formed with the smoke exhaust passage 12A, and the smoke exhaust passage 12A is used to guide the oil smoke to move toward the range hood body 10 via the smoke collecting body 20.

[0034] Furthermore, a rectifying component (not shown in the figure) can be provided in the smoke exhaust channel 12A, and the rectifying component can rectify the oil smoke entering the smoke exhaust channel 12A to reduce the probability of the oil smoke generating vortex in the smoke exhaust channel 12A, and can also reduce the probability of the oil smoke colliding with the inner wall of the smoke exhaust channel 12A, thereby reducing the noise of the oil smoke flowing through the smoke exhaust channel 12A, so as to reduce the noise of the range hood 1.

[0035] Furthermore, a silencer (not shown) may be provided on the inner wall of the smoke exhaust passage 12A to absorb the noise in the smoke exhaust passage 12A, thereby reducing the overall noise of the range hood 1 to improve the user experience.

[0036] It is understandable that the rectifier can be made of a sound-absorbing material so that the rectifier has a sound-absorbing function and can also reduce the overall noise of the range hood 1. Exemplarily, the sound-absorbing material includes but is not limited to natural plant fiber, glass fiber, rock wool, foam glass, foam metal, foam plastic, and polystyrene perlite. In other embodiments, the sound-absorbing material can also be other materials.

[0037] Please refer to Figure 2 It can be understood that the range hood 1 can also include a lifting drive component 13, the fixed end of the lifting drive component 13 is connected to the range hood body 10, and the driving end of the lifting drive component 13 is connected to the smoke collecting body 20. Along the height direction X, the lifting drive component 13 can drive the smoke collecting body 20 to move relative to the range hood body 10, so that the smoke collecting body 20 can adapt to different stove countertop heights to meet different installation requirements; it can also adapt to different smoking purposes, thereby improving the smoking quality. For example, when the oil smoke is large, the lifting drive component 13 can be used to drive the smoke collecting body 20 to move in a direction close to the stove countertop to reduce the movement path of the oil smoke outside the smoke collecting body 20 and reduce the probability of oil smoke escaping, thereby improving the smoke collecting effect of the smoke collecting body 20 and improving the smoke extraction efficiency of the range hood 1; when the stove countertop needs to be cleaned, the lifting drive component 13 can be used to drive the smoke collecting body 20 to move in a direction away from the countertop to increase the space above the stove countertop, thereby facilitating the user to clean the stove countertop. Exemplarily, the lifting drive assembly 13 may be, but is not limited to, an electric push rod, a linear motor, a gear rack and a pulley structure that mesh with each other. In the embodiment of the present application, the specific form of the lifting drive assembly 13 is not limited.

[0038] The smoke collecting body 20 may be made of metal. For example, the smoke collecting body 20 may be formed by stamping and welding A3 cold-rolled steel plate (or stainless steel plate), and the surface of the smoke collecting body 20 may be treated by phosphating and spraying, which may reduce the probability of rusting of the smoke collecting body 20, thereby allowing the range hood 11 to have a longer service life. The surface of the smoke collecting body 20 may be treated by phosphating and spraying, which may also make the smoke collecting body 20 smooth and easy to clean.

[0039] See also Figure 4-Figure 5The smoke collecting body 20 may include a smoke collecting hood 26, which is connected to the range hood body 10. The smoke collecting hood 26 has a smoke collecting chamber 20A and a plurality of smoking ports 20B. The smoke collecting chamber 20A is connected to the smoke exhaust passage 12A. The smoke collecting chamber 20A is also connected to the plurality of smoking ports 20B. In this way, the smoke enters the smoke collecting chamber 20A from the plurality of smoking ports 20B and enters the fan chamber 111A through the smoke exhaust passage 12A, and is then discharged to the outside through the smoke exhaust pipe. The smoke collecting hood 26 may be, but is not limited to, made of metal or plastic. For example, the smoke collecting hood 26 may be made of metal to improve the structural strength of the smoke collecting hood 26, thereby extending the service life of the range hood 1.

[0040] Multiple smoke outlets 20B are arranged at intervals along the circumference of the smoke collecting hood 26, that is, the smoke collecting hood 26 is provided with smoke outlets 20B in the circumference, so that the range hood 1 can suck the circumferential oil smoke into the smoke collecting chamber 20A through the smoke outlets 20B to prevent the spread of oil smoke, thereby improving the oil smoke suction effect of the range hood 1.

[0041] Furthermore, the smoke collecting body 20 also includes a partition 27, which is arranged in the smoke collecting chamber 20A. The partition 27 can divide the smoke collecting chamber 20A into a plurality of branch channels 27A, and each branch channel 27A is connected to the corresponding smoking port 20B, so that the oil smoke can enter the smoke collecting chamber 20A from the corresponding smoking port 20B. For example, when the burner of the stove is located on the left side of the smoke collecting chamber 20A, the smoking port 20B closest to the burner on the left side can draw the generated oil smoke into the smoke collecting chamber 20A, thereby improving the oil fume suction efficiency.

[0042] It should be noted that the partition 27 may be, but is not limited to, a sheet metal part or a solid cylinder. In the embodiment of the present application, there is no restriction on the specific form of the partition 27. Furthermore, the material of the partition 27 may be, but is not limited to, plastic or metal. In the embodiment of the present application, there is no restriction on the material of the partition 27. For example, the material of the partition 27 may be metal, so that the partition 27 has a higher structural strength, thereby improving the stability of the connection between the partition 27 and the smoke hood 26.

[0043] Furthermore, the smoke collecting chamber 20A can be divided into at least two branch channels 27A with different flow areas by the partition 27. It can be understood that when the range hood 1 is working, the larger the flow area of ​​the branch channel 27A, the greater the intake of oil smoke. In this way, the amount of oil smoke intake can be controlled according to the size of the flow area of ​​the branch channel 27A. For example, when a user uses a stove with two burners, and the two burners are arranged directly below the range hood 1, the partition 27 can separate the flow area of ​​the branch channel 27A located directly above the two burners to be larger, so that more oil smoke can enter the smoke collecting chamber 20A from the corresponding smoke outlet 20B, so as to improve the oil smoke extraction effect of the range hood 1.

[0044] In the embodiment of the present application, a partition 27 is arranged in the smoke collecting chamber 20A to divide the smoke collecting chamber 20A into multiple branch channels 27A, and the flow areas of at least two branch channels 27A are different. At this time, the smoke collecting chamber 20A can be divided into at least two branch channels 27A with different flow areas by the partition 27, so that the larger the flow area of ​​the branch channel 27A, the greater the air intake amount of the oil smoke. That is, the air intake amount of the oil smoke can be controlled according to the size of the flow area of ​​the branch channel 27A, so as to flexibly adjust the air intake amount of the oil smoke entering the smoke collecting chamber 20A from the smoke outlet 20B, thereby improving the oil smoke extraction effect of the range hood 1.

[0045] See also Figure 4-Figure 6 In some embodiments, the plurality of smoke ports 20B include a front smoke port 20D, a left smoke port 20E and a right smoke port 20F, and the air inlet area of ​​the front smoke port 20D is larger than the air inlet areas of the left smoke port 20E and the right smoke port 20F. It can be understood that, since a stove is usually provided under the range hood 1, the air inlet area of ​​the front smoke port 20D is set to be larger than the air inlet areas of the left smoke port 20E and the right smoke port 20F, so as to suck the oil smoke from the front smoke port 20D into the smoke collecting chamber 20A as much as possible.

[0046] Please continue reading Figure 4-Figure 6 Further, the flow channel 27A includes a front flow channel 27B, a left flow channel 27C and a right flow channel 27D, wherein the front flow channel 27B is connected to the front smoke outlet 20D, the left flow channel 27C is connected to the left smoke outlet 20E, and the right flow channel 27D is connected to the right smoke outlet 20F. The flow area of ​​the front flow channel 27B is larger than the flow area of ​​the left flow channel 27C and the flow area of ​​the right flow channel 27D. It can be understood that the range hood 1 is arranged above the stove. When the user uses the stove on the stove, the front side of the range hood 1 generates more oil smoke, so the flow area of ​​the front flow channel 27B is separated by the partition 27 to be larger, so that more oil smoke can enter the front flow channel 27B from the front smoke outlet 20D, so as to improve the oil smoke extraction effect of the range hood 1.

[0047] It should be noted that if the interval between the burners on the stove top in the left-right direction Y is large, and the front smoke outlet 20D cannot effectively suck the oil smoke into the smoke collecting chamber 20A, the range hood 1 can also suck the oil smoke into the smoke collecting chamber 20A through the left smoke outlet 20E and the right smoke outlet 20F to prevent the oil smoke from spreading. Of course, the partition 27 can adjust the flow area of ​​the front branch channel 27B, the left branch channel 27C and the right branch channel 27D according to the actual situation of the user to ensure that the range hood 1 can suck more oil smoke into the smoke collecting chamber 20A.

[0048] See also Figure 5 In some embodiments, the flow area of ​​the left branch channel 27C may be equal to or unequal to the flow area of ​​the right branch channel 27D, and this is not specifically limited in the embodiments of the present application.

[0049] Exemplarily, when the flow area of ​​the left-side branch channel 27C is equal to the flow area of ​​the right-side branch channel 27D, the air intake amount of oil smoke entering the left-side branch channel 27C from the left-side smoking port 20E is equal to the air intake amount of oil smoke entering the right-side branch channel 27D from the right-side smoking port 20F, and combined with the above-mentioned flow area of ​​the front-side branch channel 27B being larger than the flow area of ​​the left-side branch channel 27C and the flow area of ​​the right-side branch channel 27D, it can be ensured that the air intake amount of oil smoke entering the front-side branch channel 27B from the front-side smoking port 20D is larger.

[0050] See also Figure 5-Figure 6 In some embodiments, the partition 27 may include a left partition plate 271 and a right partition plate 272, both of which are disposed in the smoke collecting chamber 20A, wherein at least the left partition plate 271 and the left cavity wall of the smoke collecting chamber 20A and the rear cavity wall of the smoke collecting chamber 20A enclose a left branch channel 27C; at least the right partition plate 272 and the right cavity wall of the smoke collecting chamber 20A and the rear cavity wall of the smoke collecting chamber 20A enclose a right branch channel 27D; the right partition plate 272 and the left partition plate 271 are arranged along the collection The smoke main body 20 is spaced apart in the left-right direction Y so that at least the right partition plate 272, the left partition plate 271 and the front wall of the smoke collecting chamber 20A jointly enclose a front branch channel 27B, so that the left partition plate 271 and the right partition plate 272 divide the smoke collecting chamber 20A into independent and spaced-apart left branch channel 27C, right branch channel 27D and front branch channel 27B, and then the air intake of the oil smoke is effectively controlled according to the size of the flow area of ​​the left branch channel 27C, the right branch channel 27D and the front branch channel 27B.

[0051] Please continue reading Figure 5-Figure 6 Further, in some embodiments, the partition 27 further includes a connecting plate 273, and the connecting plate 273 is connected to the rear wall of the smoke collecting chamber 20A, that is, the connecting plate 273 can be connected to the rear wall of the smoke collecting chamber 20A by bonding, screwing, clamping, and magnetic attraction, etc., which is not limited in the embodiment of the present application. Along the left-right direction Y, the two ends of the connecting plate 273 are respectively connected to the left partition and the right partition to improve the stability of the installation of the partition 27.

[0052] Please continue reading Figure 5-Figure 6In some embodiments, the left partition plate 271, the right partition plate 272 and the connecting plate 273 can be an integrated component, that is, the partition 27 composed of the left partition plate 271, the right partition plate 272 and the connecting plate 273 is directly installed in the smoke collecting chamber 20A to improve the convenience of installing the partition 27.

[0053] Of course, the left partition plate 271, the right partition plate 272 and the connecting plate 273 can also be set separately. In this way, when one of the left partition plate 271, the right partition plate 272 and the connecting plate 273 is damaged, only the damaged part needs to be replaced to save the maintenance cost of the partition 27.

[0054] Please continue reading Figure 5-Figure 6 In some embodiments, along the direction from front to back, the distance between the left partition plate 271 and the left wall of the smoke collecting chamber 20A in the left-right direction Y gradually increases, that is, the smoke enters the left branch channel 27C from the left smoking port 20E. Since the distance between the left partition plate 271 and the left wall of the smoke collecting chamber 20A in the left-right direction Y gradually increases, the smoke will be blocked by the left partition plate 271 after entering the left branch channel 27C from the left smoking port 20E, so that the smoke can enter the smoke exhaust channel 12A.

[0055] In other embodiments, along the direction from front to back, the distance between the right partition plate 272 and the right wall of the smoke collecting chamber 20A in the left-right direction Y gradually increases, that is, the smoke enters the right branch channel 27D from the right smoking port 20F. Since the distance between the right partition plate 272 and the right wall of the smoke collecting chamber 20A in the left-right direction Y gradually increases, the smoke will be blocked by the right partition plate 272 after entering the right branch channel 27D, so that the smoke can enter the smoke exhaust channel 12A.

[0056] In some other embodiments, along the direction from front to back, the distance between the left partition plate 271 and the left cavity wall of the smoke collecting chamber 20A in the left-right direction Y gradually increases, while the distance between the right partition plate 272 and the right cavity wall of the smoke collecting chamber 20A in the left-right direction Y also gradually increases. In this way, the flow area of ​​the oil smoke in the right branch channel 27D and the left branch channel 27C is gradually reduced, so that the oil smoke can enter the smoke exhaust channel 12A through the left branch channel 27C and the right branch channel 27D.

[0057] See also Figure 4-Figure 6 In some embodiments, the smoke collecting hood 26 includes a rear shell 213 , a left shell 214 , a right shell 215 , a guide plate 212 , a top shell 221 and a grille assembly 211 .

[0058] Specifically, the left side shell 214 is connected to the left side of the rear side shell 213; the right side shell 215 is connected to the right side of the rear side shell 213; the deflector 212 is connected to the lower side of the rear side shell 213, the top shell 221 is connected to the upper side of the rear side shell 213, and the deflector 212 and the top shell 221 are arranged opposite to each other; the grille assembly 211 may include a left side grille 2113, a right side grille 2114 and a front side grille 2115, and the left side grille 2113 is connected to the left side shell 214 and the deflector The right grille 2114 is connected between the right shell 215 and the guide plate 212, the front grille 2115 is connected between the top shell 221 and the guide plate 212, and the left and right sides of the front grille 2115 are respectively connected to the left grille 2113 and the right grille 2114, wherein the rear shell 213, the left shell 214, the right shell 215, the guide plate 212, the grille assembly 211 and the top shell 221 are jointly arranged to form a smoke collecting chamber 20A.

[0059] Furthermore, the left grille 2113 has a left smoke outlet 20E, the right grille 2114 has a right smoke outlet 20F, the front grille 2115 has a front smoke outlet 20D, and the top shell 221 has a smoke exhaust port 20C connected to the smoke collecting chamber 20A, and the smoke exhaust port 20C is connected to the smoke exhaust channel 12A. In this way, when the range hood 1 is working, oil smoke can enter the smoke collecting chamber 20A from the left smoke outlet 20E, the right smoke outlet 20F and the front smoke outlet 20D, and be discharged from the smoke exhaust port 20C to the smoke exhaust channel 12A and the fan chamber 111A, and then discharged to the outside through the smoke exhaust pipe.

[0060] See also Figure 5-Figure 6 In some embodiments, the left partition plate 271 extends from the connection between the left grille 2113 and the front grille 2115 to the rear shell 213, that is, one end of the left partition plate 271 is connected to the connection between the left grille 2113 and the front grille 2115, and one end of the left partition plate 271 is connected to the inner wall surface of the rear shell 213 to improve the stability of the connection of the left partition plate 271.

[0061] Furthermore, the distance between the left partition plate 271 and the left shell 214 in the left-right direction Y gradually increases, that is, along the direction close to the rear shell 213, the distance between the left partition plate 271 and the left shell 214 in the left-right direction Y gradually increases, so that the flow area of ​​the oil smoke flowing through the left branch channel 27C gradually becomes smaller, so as to control the oil smoke intake amount of the left branch channel 27C.

[0062] Please continue reading Figure 5-Figure 6In other embodiments, the right partition plate 272 extends from the connection between the right grille 2114 and the front grille 2115 to the rear shell 213, that is, one end of the right partition plate 272 is connected to the connection between the right grille 2114 and the front grille 2115, and one end of the right partition plate 272 is connected to the inner wall surface of the rear shell 213 to improve the stability of the connection of the right partition plate 272.

[0063] Furthermore, the distance between the right partition plate 272 and the right shell 215 in the left-right direction Y gradually increases, that is, along the direction close to the rear shell 213, the distance between the right partition plate 272 and the right shell 215 in the left-right direction Y gradually increases, so that the flow area of ​​the oil smoke flowing through the right branch channel 27D gradually becomes smaller, so as to control the oil smoke intake amount of the right branch channel 27D.

[0064] See also Figure 2 In some embodiments, along the height direction X, the projection of the smoke exhaust port 20C on the guide plate 212 is staggered with the front smoke outlet 20D, the left smoke outlet 20E and the right smoke outlet 20F, thereby preventing the oil condensed in the smoke exhaust channel 12A from dripping onto the stove top through the smoke outlet 20B, and reducing the probability of the stove top being contaminated.

[0065] See also Figure 7-Figure 8 In one embodiment, the surface of the top shell 221 facing the inhalation port 20B is the condensation surface 22A. After the oil smoke enters the smoke collecting chamber 20A from the front inhalation port 20D, the left inhalation port 20E and the right inhalation port 20F, the hot oil smoke contacts the condensation surface 22A with a lower temperature and condenses into oil stains on the condensation surface 22A.

[0066] It can be understood that the height of the top shell 221 gradually decreases in the direction away from the smoke exhaust port 20C, so that the height of the condensation surface 22A gradually decreases, so that the oil stains on the condensation surface 22A can be guided to the guide plate 212 through the smoke inlet grid 211, and can flow out to the oil cup 25 through the oil outlet hole 212B. It can also prevent the oil stains from dripping onto the table through the smoking port 20B, so that the table can be kept clean.

[0067] See also Figure 2-Figure 3In some embodiments, after the oil smoke condenses into oil stains on the condensation surface 22A, in order to prevent the oil stains from dripping onto the table through the smoke outlet 20B under the action of gravity, the height of the condensation surface 22A gradually decreases along the direction close to the smoke outlet 20C and forms an oil dripping level 22B, so that the oil stains can move along the condensation surface 22A to the oil dripping level 22B under the action of gravity. Furthermore, the projection of the oil dripping level 22B along the height direction X on the guide plate 212 is staggered with the front smoke outlet 20D, the left smoke outlet 20E, and the right smoke outlet 20F, so that the oil stains gathered at the oil dripping level 22B can drip onto the guide plate 212 (please refer to the flow path of the oil stains for details). Figure 3 The front smoking port 20D, the left smoking port 20E and the right smoking port 20F are used to prevent oil stains from dripping onto the countertop, so that the countertop can be kept clean without the need for the user to repeatedly clean the countertop, thereby providing the user with a better user experience.
