Description

Technical Field

[0002] The range hood works based on the principle of fluid dynamics. The fumes are sucked and exhausted by the centrifugal fan installed inside the range hood, and some grease particles are filtered out by the filter. The centrifugal fan includes a volute, an impeller installed in the volute, and a motor that drives the impeller to rotate. When the impeller rotates, negative pressure suction is generated in the center of the fan, and the smoke is sucked into the fan through the smoke inlet of the smoke collector. After being accelerated by the fan, it is collected by the volute and guided to be discharged outdoors.

[0003] In the relevant technical field, after the oil smoke is sucked into the smoke collecting body through the smoke outlet, it will condense on the inner wall of the smoke collecting body.

DETAILED DESCRIPTION

[0027] 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.

[0028] Please refer to Figure 1-3 The embodiment of the present application provides a range hood 1, comprising a range hood body 10 and a smoke collecting body 20. The range hood body 10 comprises a fan assembly 11 and a flue assembly 12, one end of the flue assembly 12 is connected to the fan assembly 11, and the other end 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 countertop.

[0029] The fan assembly 11 includes a fan box 111 and a fan 112. The fan box 111 has a fan cavity 111A, and the fan 112 is arranged in the fan cavity 111A. 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 range hood body 10 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 during the smoke exhaust process, in order to prevent the backflow of oil smoke, the range hood is usually equipped with a check valve 14.

[0030] It is understandable that the fan box 111 is usually made of metal. Exemplarily, 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. The surface of the fan box 111 is treated with phosphating and spraying, which can also make the fan box 111 smooth and easy to clean.

[0031] The flue assembly 12 is formed with a smoke exhaust channel 12A for guiding the oil smoke to move toward the range hood body 10 through the smoke collecting body 20 .

[0032] 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.

[0033] 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.

[0034] 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. Exemplary sound-absorbing materials include but are not limited to natural plant fibers, glass fibers, rock wool, foam glass, foam metal, foam plastic, and polystyrene perlite. In other embodiments, the sound-absorbing material can also be other materials.

[0035] Please refer to Figure 3It can be understood that the range hood 1 can also include a driving structure 13, the fixed end of the driving structure 13 is connected to the range hood body 10, and the driving end of the driving structure 13 is connected to the smoke collecting body 20. Along the height direction X, the driving structure 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 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 driving structure 13 can drive the smoke collecting body 20 to move in a direction close to the 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 collection effect of the smoke collecting body 20 and improving the smoke extraction efficiency of the range hood 1; when the countertop needs to be cleaned, the driving structure 13 can drive the smoke collecting body 20 to move in a direction away from the countertop to increase the space above the countertop, thereby facilitating the user to clean the countertop. Exemplarily, the driving structure 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 driving structure 13 is not limited.

[0036] Please refer to Figure 3 and Figure 4 The smoke collecting body 20 has a smoke collecting chamber 20A, and the smoke collecting body 20 includes a flow guide component 21 and a condensation component 22. The flow guide component 21 has a smoke inlet 20B connected to the smoke collecting chamber 20A. The condensation component 22 is connected to the flow guide component 21. The condensation component 22 has a smoke outlet 20C connected to the smoke collecting chamber 20A. The smoke outlet 20C is connected to the smoke exhaust channel 12A. The condensation component 22 has a condensation surface 22A arranged toward the smoke inlet 20B. After the oil smoke enters the smoke collecting chamber 20A from the smoke inlet 20B, the oil smoke with heat contacts the condensation surface 22A of the condensation component 22 with a lower temperature, and can condense into oil stains on the condensation surface 22A.

[0037] 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 is gradually reduced in the direction close to the smoke outlet 20C to form an oil dripping level 22B, so that the oil stains can move to the oil dripping level 22B along the condensation surface 22A under the action of gravity. Furthermore, the projection of the oil dripping level 22B on the guide component 21 along the height direction X is staggered with the smoke outlet 20B, so that the oil stains gathered at the oil dripping level 22B can drip onto the guide component 21 (please refer to the flow path of the oil stains for details). Figure 4 The invention also provides a novel structure for the table top, which is shown by the dotted line with an arrow in the middle, thereby preventing oil stains from dripping onto the table top through the smoking port 20B, so that the table top can be kept clean and the user does not need to repeatedly clean the table top, thereby providing the user with a better user experience.

[0038] It is understandable that the smoke collecting body 20 can be made of metal. For example, the smoke collecting body 20 can be stamped and welded from A3 cold-rolled steel plate (or stainless steel plate), and the surface of the smoke collecting body 20 is treated with phosphating spraying, which can reduce the probability of rusting of the smoke collecting body 20, thereby allowing the range hood 1 to have a longer service life. The surface of the smoke collecting body 20 is treated with phosphating spraying, which can also make the smoke collecting body 20 smooth and easy to clean.

[0039] Please refer to Figure 3 and Figure 4 In one embodiment, the projection of the oil dripping position 22B on the guide assembly 21 along the height direction X has a first spacing dimension L1 with the smoke outlet 20B, and L1 satisfies: 5mm≤L1≤15mm, so that the oil dripping position 22B can be farther away from the smoke outlet 20B to reduce the probability of oil stains splashing to the smoke outlet 20B, thereby ensuring that all oil stains can be received by the guide plate 212. At the same time, the occupation of the internal space of the smoke collecting chamber 20A can be reduced, so that the size of the smoke collecting body 20 is smaller, so that the overall size of the range hood 1 is smaller, so as to facilitate the production and installation of the range hood 1.

[0040] If L1≤5mm, the oil dripping position 22B is close to the smoke outlet 20B, resulting in a high probability of oil stains splashing to the smoke outlet 20B, resulting in a high probability of oil stains dripping onto the countertop, which is easy to contaminate the countertop. If L1≥15mm, the internal space of the smoke collecting chamber 20A is occupied to a large extent, making the size of the smoke collecting body 20 larger, resulting in a larger overall size of the range hood 1, which is inconvenient to produce and install the range hood 1. In the embodiment of the present application, the first spacing dimension L1 preferably satisfies 8mm≤L1≤12mm.

[0041] Please refer to Figure 3 and Figure 4 In one embodiment, along the height direction X, the projection of the smoke exhaust port 20C on the guide component 21 is also staggered with the smoking port 20B, thereby preventing the oil condensed in the smoke exhaust channel 12A from dripping onto the table through the smoking port 20B, and also reducing the probability of the table being contaminated.

[0042] Specifically, the projection of the smoke outlet 20C on the guide assembly 21 along the height direction X has a second spacing dimension L2 with the smoke outlet 20B, and L2 satisfies: 5mm≤L2≤15mm, so that the oil dripping position 22B can be farther away from the smoke outlet 20B, so as to reduce the probability of oil stains splashing to the smoke outlet 20B, thereby ensuring that all oil stains can be received by the guide plate 212. At the same time, the occupation of the internal space of the smoke collecting chamber 20A can be reduced, so that the size of the smoke collecting body 20 is smaller, so that the overall size of the range hood 1 is smaller, so as to facilitate the production and installation of the range hood 1.

[0043] If L2≤5mm, the oil dripping position 22B is close to the smoke outlet 20B, resulting in a high probability of oil stains splashing to the smoke outlet 20B, resulting in a high probability of oil stains dripping onto the countertop, which is easy to contaminate the countertop. If L2≥15mm, the internal space of the smoke collecting chamber 20A is occupied to a large extent, making the size of the smoke collecting body 20 larger, resulting in a larger overall size of the range hood 1, which is inconvenient to produce and install the range hood 1. In the embodiment of the present application, the second spacing dimension L2 preferably satisfies 8mm≤L2≤12mm.

[0044] Please refer to Figure 3 and Figure 4 In one embodiment, the condensation component 22 includes a top plate 221, which is connected to the guide component 21. The surface of the top plate 221 facing the smoking port 20B is the condensation surface 22A. Along the direction approaching the smoke exhaust port 20C, the height of the top plate 221 gradually decreases, so that the height of the condensation surface 22A gradually decreases and forms an oil dripping level 22B, so as to guide the oil to move along the condensation surface 22A to the oil dripping level 22B, and gather at the oil dripping level 22B until it drips onto the guide component 21, thereby preventing the oil from dripping onto the countertop through the smoking port 20B.

[0045] It can be understood that, in another embodiment, the condensation component 22 includes a top plate 221, which is connected to the guide component 21, and the surface of the top plate 221 facing the smoking port 20B is the condensation surface 22A; wherein, the top plate 221 has a cross-section along the height direction X, and the area of ​​the cross-section gradually increases toward the direction approaching the smoke exhaust port 20C, so that the height of the condensation surface 22A gradually decreases and forms an oil dripping level 22B, and can also guide the oil stains to move along the condensation surface 22A to the oil dripping level 22B, and gather at the oil dripping level 22B until they drip onto the guide component 21.

[0046] It can be understood that, in another embodiment, the condensation component 22 can also include a top plate 221 and a condensation plate (not shown in the figure), the top plate 221 is connected to the guide component 21; the condensation plate is connected to the side of the top plate 221 facing the guide component 21, and the surface of the condensation plate facing the smoke collecting chamber 20A is the condensation surface 22A; wherein, at least one of the condensation plate and the top plate 221 has a cross-section along the height direction X, and the area of ​​the cross-section gradually increases in the direction approaching the smoke exhaust port 20C, so that the height of the condensation surface 22A gradually decreases and forms an oil dripping level 22B, and can also guide the oil to move along the condensation surface 22A to the oil dripping level 22B, and gather at the oil dripping level 22B until it drips onto the guide component 21.

[0047] It is understandable that the condensation surface 22A includes at least one of an arc surface or multiple planes connected in sequence, both of which can guide the oil to move along the condensation surface 22A to the oil dripping position 22B. In the embodiment of the present application, there is no specific limitation on the form of the condensation surface 22A and the composition of the condensation surface 22A.

[0048] Please refer to Figure 3 and Figure 4 In one embodiment, the top plate 221 has an angle α with the horizontal direction Y, and α satisfies: 5°≤α≤10°; this can make the oil stains flow more smoothly on the condensation surface 22A, so that the oil stains gather at the oil dripping position 22B, and drip from the oil dripping position 22B to the guide component 21, thereby reducing the probability of the oil stains dripping directly from the condensation surface 22A to the table through the smoking port 20B; at the same time, the smoke collecting chamber 20A can be made larger, so that the air intake space of the smoke collecting body 20 is more sufficient, which is beneficial to the increase of the air volume of the whole range hood 1, thereby improving the smoke collection effect of the smoke collecting body 20.

[0049] If the angle α is less than or equal to 5°, the oil will not flow smoothly on the condensation surface 22A due to the small angle α, and the oil will easily gather on the condensation surface 22A. The gathered oil will easily drip onto the table through the smoking port 20B under the action of gravity, causing the table to be contaminated. If the angle α is greater than or equal to 10°, the smoke collecting cavity 20A will be smaller due to the large angle α, resulting in insufficient air intake space of the smoke collecting body 20, reducing the smoke collecting effect of the smoke collecting body 20.

[0050] Please refer to Figure 3 and Figure 4 In one embodiment, the guide assembly 21 includes a smoke inlet grid 211 and a guide plate 212. The smoke inlet grid 211 is connected to the side of the condensation assembly 22 away from the smoke exhaust port 20C, and the smoke inlet grid 211 has a smoking port 20B; the guide plate 212 is connected to the side of the smoke inlet grid 211 away from the condensation assembly 22; wherein, along the height direction X, the projection of the oil dripping level 22B is on the guide plate 212, thereby preventing oil stains from dripping onto the table top, so that the table top can be kept clean.

[0051] Furthermore, the smoke inlet grid 211 may include three grid parts, which are connected in sequence, and each grid part has a smoke intake port 20B. The three grid parts are respectively used to inhale the smoke in front and on both sides of the range hood 1, thereby improving the smoke extraction efficiency of the range hood 1 and reducing the movement path of the smoke to reduce the probability of smoke escape, thereby improving the smoke extraction effect of the range hood 1 on the smoke.

[0052] Furthermore, the top plate 221 includes three top plate portions 2211, and the three top plate portions 2211 are connected in sequence, and the three top plate portions 2211 have a first connection side 2211A and a second connection side 2211B. The first connection sides 2211A of the three top plate portions 2211 are respectively connected to the three grid portions one by one, and the second connection sides 2211B of the three top plate portions 2211 are jointly arranged to form a smoke exhaust port 20C. Along the direction close to the second connection side 2211B, the height of each top plate portion 2211 gradually decreases, and the side of the three top plate portions 2211 facing the guide assembly 21 is a condensation surface 22A, and the oil dripping position 22B is located on the side of each top plate portion 2211 close to the second connection side 2211B, so that each condensation surface 22A can guide the oil to the second connection side 2211B, thereby reducing the probability of the oil on each condensation surface 22A dripping onto the table through the smoking port 20B.

[0053] It is understood that in other embodiments, the smoke inlet grid 211 may also include four grid parts, and the top plate 221 may also include four top plate parts 2211, and the four grid parts are arranged in a one-to-one correspondence with the four top plate parts 2211, so that the condensation surface 22A of each top plate part 2211 condenses the oil smoke inhaled by the corresponding smoking port 20B, and guides the oil stains on each condensation surface 22A to move to the oil dripping position 22B. It is understood that in the application embodiment, there is no specific restriction on the number of grid parts included in the smoke inlet grid 211, and there is no specific restriction on the number of top plate parts 2211 included in the top plate 221, and they can be selected according to the specific smoking plan.

[0054] Please refer to Figure 3 In one embodiment, the smoke collecting body 20 further includes a side panel 23 and a back panel 24, the side panel 23 is connected to at least a portion of the smoke inlet grid 211; the back panel 24 is connected to the side panel 23 and the top panel 221, and together with the side panel 23, the condensation assembly 22, the smoke inlet grid 211 and the guide plate 212, forms a smoke collecting chamber 20A.

[0055] Please refer to Figure 3In one embodiment, the guide plate 212 has a guide surface 212A. Along the height direction X, the height of the guide surface 212A gradually decreases in the direction away from the smoke inlet grid 211 and forms an oil outlet 212B. The smoke collecting body 20 also includes an oil cup 25. The oil cup 25 is detachably connected to the side of the guide plate 212 near the oil outlet 212B. The oil cup 25 is used to receive the oil flowing out of the oil outlet 212B, which can facilitate the centralized cleaning of the oil in the oil cup 25 to improve the user's convenience in cleaning the oil. Exemplarily, a plurality of oil outlets 212B can be provided on the guide plate 212 to reduce the probability of a single oil outlet 212B being blocked and causing the oil to gather in the smoke collecting chamber 20A. For example, the oil outlet 212B on the guide plate 212 can be provided with 2, 3, 4... In the application embodiment, there is no specific restriction on the number of oil outlets 212B.

[0056] It can be understood that in order to ensure that the oil flowing out of the oil outlet holes 212B can be received by the oil cup 25 , in the height direction X, the projections of all the oil outlet holes 212B are within the oil cup 25 .

[0057] It is understandable that the detachable connection between the oil cup 25 and the guide plate 212 includes but is not limited to a snap connection and a screw connection. In other embodiments, the detachable connection between the oil cup 25 and the guide plate 212 may also be in other forms.

[0058] It can be understood that the guide surface 212A can also have an angle α with the horizontal direction Y, and α satisfies: 5°≤α≤10°; this can make the oil flow on the guide surface 212A smoother, so that the oil can flow to the oil cup 25 through the oil outlet hole 212B, reducing the probability of oil remaining on the guide surface 212A, so as to facilitate cleaning of the guide surface 212A; at the same time, the smoke collecting chamber 20A can be made larger, so that the air intake space of the smoke collecting body 20 is more sufficient, which is beneficial to the increase of the air volume of the whole machine, thereby improving the smoke gathering effect of the smoke collecting body 20.

[0059] If the angle α is less than or equal to 5°, the oil will not flow smoothly on the guide surface 212A due to the small angle α, and the oil will easily gather on the guide surface 212A, making it more difficult for the user to clean the guide surface 212A. If the angle α is greater than or equal to 10°, the overall size of the smoke collecting body 20 will be larger due to the large angle α, and the overall size of the range hood 1 will be larger, which is inconvenient for the production and installation of the range hood 1.

[0060] Please refer to Figure 5 and Figure 6In one embodiment, the height of the smoke inlet grid 211 gradually decreases in the direction approaching the guide plate 212, and the height of the condensation surface 22A gradually decreases in the direction away from the smoke exhaust port 20C, 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.

[0061] It can be understood that the specific manner in which the height of the condensation surface 22A gradually decreases in the direction away from the smoke exhaust port 20C can be analogous to the scheme in which the height of the condensation surface 22A gradually decreases in the direction close to the smoke exhaust port 20C, which will not be repeated here.

[0062] Please refer to Figure 5 and Figure 6 Specifically, the top plate 221 has an angle α with the horizontal direction Y, and α satisfies: 5°≤α≤10°; this can make the oil stain flow more smoothly on the condensation surface 22A, so that the oil stain flows to the smoke inlet grille 211, and is guided from the smoke inlet grille 211 to the guide plate 212, thereby reducing the probability of the oil stain dripping directly from the condensation surface 22A to the table through the smoking port 20B; at the same time, the smoke collecting chamber 20A can be made larger, so that the air intake space of the smoke collecting body 20 is more sufficient, which is conducive to the increase of the air volume of the whole machine, thereby improving the smoke collection effect of the smoke collecting body 20; and the overall size of the smoke collecting body 20 can be made smaller, so that the overall size of the range hood 1 is smaller, which is convenient for the production and installation of the range hood 1.

[0063] If the angle α is less than or equal to 5°, the oil stains will not flow smoothly on the condensation surface 22A due to the small angle α, and the oil stains will easily gather on the condensation surface 22A. The gathered oil stains will easily drip onto the table through the smoke outlet 20B under the action of gravity, causing the table to be polluted. The smoke collecting chamber 20A will also be smaller, resulting in insufficient air intake space of the smoke collecting body 20, reducing the smoke collection effect of the smoke collecting body 20. If the angle α is greater than or equal to 10°, the overall size of the smoke collecting body 20 will be larger due to the large angle α, resulting in a larger overall size of the range hood 1, which is inconvenient for the production and installation of the range hood 1.

[0064] Please refer to Figure 5 and Figure 6Furthermore, the smoke inlet grid 211 includes a main body 2111 and a plurality of folding portions 2112. The main body 2111 is connected to the guide plate 212 and the condensation assembly 22, and has a plurality of inhalation ports 20B, and two adjacent inhalation ports 20B are arranged at intervals; the plurality of folding portions 2112 are all connected to a side of the main body 2111 facing the condensation assembly 22, and the plurality of folding portions 2112 are arranged one by one with the plurality of inhalation ports 20B, and each folding portion 2112 is arranged around the opposite The folded portions 2112 should be arranged on the peripheral side of the smoking port 20B, and folded and extended from the peripheral side of the smoking port 20B toward the condensation surface 22A. An interval is set between two adjacent folded portions 2112, and an oil guide channel 211A is formed between the multiple folded portions 2112 and the main body 2111, so that the oil on the condensation surface 22A can be guided to the guide plate 212 through the oil guide channel 211A, thereby reducing the probability of oil detaching from the grille bars, thereby reducing the probability of oil dripping onto the table top, thereby keeping the table top clean.

[0065] Please refer to Figure 3 Along the direction close to the smoke exhaust port 20C, the height of the condensation surface 22A gradually decreases and forms an oil dripping level 22B, so as to gather the oil to the oil dripping level 22B and drip it to the guide plate 212. The oil has a shorter travel route, which can reduce the probability of oil remaining on the inner wall of the smoke collecting chamber 20A, so as to facilitate the cleaning of the smoke collecting body 20 and improve the cleaning efficiency.

[0066] Please refer to Figure 5 , the height of the condensation surface 22A gradually decreases in the direction away from the smoke exhaust port 20C, so that the oil stains on the condensation surface 22A are guided to the guide plate 212 through the smoke inlet grid 211. This oil guiding scheme can make the smoke collecting chamber 20A larger, so that the air intake space of the smoke collecting body 20 is more sufficient, which is beneficial to the increase of the air volume of the range hood 1 as a whole, thereby improving the smoke collection effect of the smoke collecting body 20.

[0067] The above two oil guiding solutions can both prevent the oil condensed on the condensation surface 22A from dripping onto the table top through the smoking port 20B, thereby keeping the table top clean.
