Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of kitchen appliances, and specifically relates to a range hood. Background Art
[0002] A range hood is an electrical device installed above the kitchen stove, mainly used to absorb and discharge the fumes generated during cooking. When in use, the fumes enter the range hood through the air hood under the negative pressure of the fan for collection and treatment, thereby ensuring the air quality in the kitchen. However, when the fumes pass through the air hood of the range hood, they will condense on the surface of the air hood to form oil droplets due to temperature drop and other reasons. When these oil droplets gather to a certain extent, they will drip onto the stove or kitchen utensils below under the action of gravity, forming unhygienic and unsightly oil spots and oil dripping phenomena.
[0003] To solve this technical problem, the current range hoods usually tilt the air collecting hood of the range hood, and set multiple sets of longitudinal integrated oil guide grooves from top to bottom on the surface of the air collecting hood to form an oil guide hood. At the bottom of the oil guide groove, there will be an oil collection box, so that the oil droplets condensed on the surface of the oil guide hood can slide along the oil guide groove under the action of gravity and finally drip into the oil collection box to complete the collection of oil droplets. In theory, this not only effectively reduces the phenomenon of oil droplets dripping directly on the stove or kitchen utensils, and improves the hygiene and aesthetics of the kitchen; it can also extend the service life of the equipment and reduce the safety hazards caused by the accumulation of oil stains.
[0004] However, the applicant found that, on the one hand, although the longitudinally integrated oil guide groove can realize the all-round collection of oil droplets in the direction of oil fume escape, in actual use, the dripping process of oil droplets in the oil guide groove is not controlled. Since the amount of oil droplets is not large, many oil droplets will adhere to the surface of the oil guide groove in the form of hanging on the wall during the flow process, and the actual amount of oil dripping into the oil collection box is not high. On the other hand, the design of the oil guide groove often affects the design of the range hood air inlet channel, which may cause the oil fume to be unable to be effectively absorbed and diffuse into the kitchen air, reducing the user experience. Summary of the invention
[0005] In order to solve the above technical problems, the present application provides a range hood, which is specifically implemented through the following technical solutions:
[0006] A range hood comprises a hood body, wherein the lower surface of the hood body is provided with an air inlet channel, and an oil collecting assembly for collecting oil droplets; the oil collecting assembly comprises an oil receiving piece, and two groups of guide groove groups distributed on both sides of the central axis of the oil receiving piece; the guide groove group comprises a plurality of guide grooves, and the guide grooves are provided with oil outlets; the oil receiving piece comprises a mounting portion for fixing on the lower surface of the hood body, and oil grooves arranged on both sides of the mounting portion; the oil grooves are arranged obliquely, and are respectively used to receive oil droplets from the oil outlets of the guide grooves in the two groups of guide groove groups and transmit them to the discharge end of the oil receiving piece.
[0007] Preferably, the guide grooves are arranged in an array along the width direction of the lower surface of the wind shield body.
[0008] In the present application, the so-called width direction refers to the axial direction in which the user approaches or moves away from the range hood during cooking. Under normal circumstances, this direction corresponds to the side with the smaller size of the lower surface of the hood body, that is, the wide side of the rectangle, but it does not exclude specific circumstances, such as a specific model of single-stove range hood, which corresponds to the side with the larger size of the lower surface of the hood body, that is, the long side of the rectangle. It should be understood that the so-called array setting does not require that each guide groove in the guide groove group be formed on the lower surface of the hood body at a completely consistent angle or even the same structure, as long as the oil droplets from the oil outlets of several guide grooves in the same guide groove group can drip into the same oil groove to achieve the research and development purpose.
[0009] Preferably, more than two groups of the oil collecting assembly array are arranged along the length direction of the lower surface of the wind shield body.
[0010] In the technical solution, the length direction of the lower surface of the wind hood main body corresponds to the above-mentioned width direction.
[0011] Preferably, the air inlet channel is arranged between two adjacent oil collecting components.
[0012] Preferably, an inclined surface is formed between the air inlet channel and two adjacent oil collecting assemblies for transferring oil droplets at the air inlet channel opening to the guide groove.

Further preferably, the length of the guide groove is between 4 and 7 cm, and the height difference between the oil outlet of the guide groove and the lowest point of the oil tank of the oil receiving part is between 2 and 5 cm.
[0014] Preferably, the lower surface of the wind shield body is arranged parallel to the oil groove, and the angle between the oil outlet direction of the guide groove and the downward direction of the oil groove is 5 to 85 degrees. More preferably, the angle between the oil outlet direction of the guide groove and the downward direction of the oil groove is 30 to 60 degrees.
[0015] Preferably, the range hood further comprises an oil box, and a connecting plate for transferring oil droplets from the discharge end of the oil tank to the inside of the oil box, wherein the connecting plate is connected to the lower surface of the hood body.
[0016] Preferably, an oil level reminder component for reminding the oil level of the oil box is provided inside the oil box.
[0017] Preferably, the oil level reminder assembly includes a suspension member slidably connected to the inner wall of the oil box.
[0018] Preferably, the suspension members are arranged in two groups; the oil level reminder assembly further comprises an oil level reminder line arranged between the suspension members.
[0019] Compared with the prior art, this application has the following beneficial effects:
[0020] The present application simultaneously sets an air inlet channel and an oil collecting assembly on the lower surface of the air hood main body, thereby shortening the length of the guide groove compared to the existing longitudinal integrated guide groove design. Oil droplets formed on the surface of the guide groove can quickly slide through the oil outlet portion into the oil tank, thereby avoiding excessive stay of oil stains on the surface of the guide groove to form wall-hanging oil stains, and making it easier to clean the air hood main body.
[0021] The present application arranges an oil receiving piece to transmit the oil droplets dripping from the oil outlet of multiple groups of guide grooves. It can use the gravity of the oil droplets themselves and the impact formed by the falling process of the oil droplets to continuously flush the inner wall of the oil groove, thereby solving the current technical problems that the oil stains on the inner wall of the oil guide groove drip slowly, easily form wall hangings, and the oil droplet collection efficiency of the oil box is low.
[0022] The present application implements a special structural design for the oil collecting piece and the guide groove in the oil collecting assembly, thereby solving the technical problem of poor oil fume absorption effect caused by excessive obstruction of the oil fume by the outer wall of the oil collecting piece due to the air inlet channel being arranged on the lower surface of the air hood body, thereby achieving a dynamic balance between oil fume absorption and oil droplet collection.
[0023] The present application arranges the air inlet channel between two adjacent oil collecting components and arranges an inclined surface between the two. The oil droplets condensed at the air inlet channel opening will flow along the inclined surface to the guide groove, thereby solving the technical problem of poor oil droplet collection effect at the air inlet channel opening caused by the simultaneous arrangement of the air inlet channel and the guide groove on the lower surface of the wind hood body.
[0024] The present application adjusts the length of the guide groove itself and further designs the horizontal height difference between the oil outlet of the guide groove and the lowest point of the oil groove of the oil receiving piece. This can effectively utilize the potential energy difference during the falling process of oil droplets of a specific weight, regulate the flow speed of the oil droplets in the oil groove, and reduce the residence time of the oil droplets on the inner wall of the oil groove, thereby improving the collection efficiency of the oil droplets and reducing the difficulty and frequency of daily maintenance of the oil receiving piece.
[0025] The present application arranges the lower surface of the air hood body to be parallel and inclined to the oil groove, and appropriately adjusts the angle between the oil outlet direction of the guide groove and the downward inclined direction of the oil groove. On the one hand, gravity can be fully utilized as the main oil guiding power of the oil guide groove; on the other hand, the number of guide grooves can be increased to meet the oil guiding needs of a large amount of oil smoke.
[0026] The design of the connection surface of the present application ensures that the oil droplets collected through the guide groove can be smoothly transferred from the discharge end of the oil tank to the oil box, reducing the risk of oil droplets suspended in the air or splashing around, and improving the safety of the system. Furthermore, the present application sets two sets of suspension parts and sets an oil volume prompt line between the suspension parts. When the oil inside the oil box reaches a certain volume, the user can be prompted to handle the oil in time to avoid safety problems caused by oil overflow. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0032] The present application will be further described below in the form of specific embodiments. Those of ordinary skill in the art will be able to implement the present application based on these descriptions. In addition, the embodiments of the present application involved in the following description are generally only embodiments of a part of the present application, rather than all embodiments. Therefore, based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative work should fall within the scope of protection of the present application.
[0033] Example 1
[0034] This embodiment discloses a range hood, which includes:
[0035] The hood body is used to store and discharge the oil smoke sucked by the range hood fan, and its lower surface is provided with an air inlet channel 100 and an oil collection assembly 200 for collecting oil droplets. Usually, the lower surface of the hood body is installed just above the stove to collect the oil smoke and condensed water vapor generated during cooking.
[0036] Specifically, in this embodiment, the oil collecting assembly 200 includes an oil receiving member 210, and two groups of guide groove groups distributed on both sides of the central axis of the oil receiving member 210; the guide groove group includes a plurality of guide grooves 220 arranged in an array along the width direction of the lower surface of the hood body, and the guide groove 220 is provided with an oil outlet 221; the oil receiving member 210 includes a mounting portion 211 for fixing on the lower surface of the hood body, and an oil groove 212 mirror-set on both sides of the mounting portion 211; the oil groove 212 is tilted along the width direction of the lower surface of the hood body, and is used to receive the oil droplets of the guide groove oil outlet 221 in the guide groove group and transmit it to the discharge end of the oil receiving member. In this embodiment, by making a special design for the docking oil member 210 - mirror-setting the oil grooves along both sides of the mounting portion 211, the technical problem of limited designable area of the air inlet channel 100 caused by the excessive area occupied by the oil receiving member 210 on the lower surface of the hood body, or even blocking the amount of smoke in the air inlet channel 100, which causes the range hood to have a poor oil fume absorption effect. In addition, since the air inlet channel 100 in this embodiment is arranged on the lower surface of the hood body, the oil smoke will rise to the lower surface of the hood body under the action of the fan, so the oil smoke collection burden at this position is relatively greater. The above design of the oil receiving member 210 can also reduce the contact area between the oil receiving member 210 and the oil smoke, and reduce the formation of oil droplets on the outer wall of the oil receiving member 210. Further, in this embodiment, the oil receiving member 210 is inclined and is made of an oleophobic material. Therefore, although oil droplets are formed on its outer wall, they can still slide down along the inclined oil receiving member 210 to the designated oil drop collection position.
[0037] In order to simplify the structural design of the guide groove 220, in this embodiment, the lower surface of the hood body is arranged parallel to the oil groove 212, that is, the lower surface of the hood body is arranged obliquely. More specifically, along the direction away from the user, the lower surface of the hood body and the oil groove 212 are arranged obliquely downward. Further, the guide groove 220 is a groove arranged on the lower surface of the hood body, and the angle between the direction of the oil outlet 221 of the oil guide groove and the oblique downward direction of the oil groove 212 is 60°. Of course, it can be understood that in other embodiments, this angle can also be selected from any value in the range of 5 to 85°. Through the oblique arrangement of the lower surface of the hood body and the guide groove 220, the guide groove 220 can achieve oil conduction with the help of gravity, without the need for special structural design, reducing the difficulty of cleaning the special-shaped parts on the lower surface of the hood body. In addition, the inclined guide groove 220 can arrange more guide channels on the same lower surface of the wind shield body, thereby increasing the oil droplet collection effect on the limited lower surface of the wind shield body and reducing the technical problem of a small number of guide grooves 220 that can be arranged due to the area occupied by the air inlet channel 100.
[0038] In this embodiment, along the length direction of the lower surface of the wind shield body, the oil collecting components 200 are arranged in three groups, and the air inlet channel 100 is arranged between two adjacent oil collecting components 200. In order to solve the technical problem that the air inlet channel 100 and the guide groove 220 are synchronously arranged on the lower surface of the wind shield body, resulting in poor oil droplet collection effect at the position of the air inlet channel 100, in this embodiment, an inclined surface for transferring oil droplets from the air inlet channel 100 to the guide groove 220 is formed between the air inlet channel 100 and the two adjacent oil collecting components 200. Therefore, the oil droplets condensed around the air inlet channel opening can slide along the inclined surface to the vicinity of the guide groove 220, and finally enter the inside of the guide groove 220, and flow along the guide groove 220 to the guide groove oil outlet 221.
[0039] In order to shorten the residence time of oil stains in the oil guide groove 220 and the oil groove 212, the length of the guide groove 220 is between 2 and 10 cm; the horizontal height difference between the oil outlet 221 of the guide groove (i.e., the lower surface of the wind cover body) and the lowest point of the oil groove 212 of the oil receiving part is 4 cm. Of course, it can be understood that in other embodiments, the height difference can also be selected from 1 to 8 cm. In this embodiment, by adjusting the length of the guide groove 220 itself, the weight of the oil droplets can be controlled. Further, by designing the horizontal height difference between the oil outlet of the guide groove and the lowest point of the oil groove 212 of the oil receiving part, the potential energy difference of the falling process of oil droplets of a specific weight can be effectively utilized to regulate the flow speed of the oil droplets in the oil groove 212, and reduce the residence time of the oil droplets on the inner wall of the oil groove 212, thereby improving the collection efficiency of the oil droplets and reducing the difficulty and frequency of daily maintenance of the oil receiving part 210.
[0040] In order to increase the convenience of cleaning the lower surface of the air hood body, the oil collecting piece mounting portion 211 in this embodiment is slidably connected to the lower surface of the air hood body, and the lower end of the mounting portion 211 is mirror-imaged outward with the mounting portion 211 as the axis to form an open C-shaped piece, and the oil groove 212 is formed inside the C-shaped piece. The oil groove is open upward and is used to receive oil droplets flowing out of the oil outlet portion 221 of the guide groove.
[0041] The oil box 300 is used to receive the oil droplets flowing out of the discharge end of the oil receiving piece. In order to ensure that the oil droplets collected through the oil guide groove 220 can be smoothly transferred from the oil outlet of the guide groove to the oil box 300, reduce the risk of oil droplets suspended in the air or splashing around, and improve the safety of the system, a connecting surface 400 is also provided in this embodiment. Specifically, the connecting surface 400 is an arc-shaped plate, which is connected to the end away from the user with the lower surface of the inclined wind hood body, and the connecting surface 400 is connected to the discharge end of the oil receiving piece of the three groups of oil collection components 200. Therefore, as the amount of oil in the internal oil groove 212 of the oil receiving piece 210 continues to increase, the oil will flow from the discharge end of the oil receiving piece to the connecting surface 400, and then under the guidance of the connecting surface 400, it will flow into the oil box 300.
[0042] Considering that the oil droplet collection efficiency of the oil box 300 is higher than that of the existing range hood with a longitudinal integrated oil guide groove, in order to avoid safety problems caused by overflow when the oil inside the oil box reaches a certain volume, an oil volume reminder component 310 for reminding the oil volume of the oil box is also provided inside the oil box 300 of the present embodiment. Specifically, the oil volume reminder component 310 includes a suspension 311 slidably connected to the inner wall of the oil box 300; the suspension 311 is provided in two groups; the oil volume reminder component 310 also includes an oil volume reminder line 312 fixedly arranged between the suspensions 311; the oil volume reminder line 312 can be in eye-catching colors such as red, yellow or green to achieve a better oil volume reminder effect.
[0043] During the use of the range hood disclosed in this embodiment, the oil smoke rises to the lower surface of the hood body under the negative pressure of the fan. At this time, most of the oil smoke will enter the inside of the hood body through the air inlet channel 100, and finally the oil smoke will be discharged through the air duct 500. However, at the same time, some of the oil smoke will liquefy on the lower surface of the hood body to form oil droplets when it contacts the low-temperature materials such as the lower surface of the hood body. Specifically, the hood body of this application is made of oleophobic material, and the oil droplets condensed around the air inlet channel can slide along the inclined surface to the vicinity of the guide groove 220, and finally enter the inside of the guide groove 220. Further, the oil droplets inside the inclined guide groove 220 will flow to the oil outlet part 221 of the guide groove 220 under the action of gravity along the direction of the oil outlet part 221 of the guide groove 220, and then drip into the oil groove 212 of the oil receiving part. Inside the same oil collecting component 200, the oil droplets dripping at different positions will continuously flush the inner wall of the oil groove 212, driving the oil droplets to flow quickly to the discharge end of the oil groove. Finally, based on the connection relationship between the connection surface 400 and the discharge end, when the oil droplets at the discharge end gather to a certain extent, the oil will flow along the connection surface 400 to the inside of the oil box 300 to complete the collection of oil smoke. As the oil droplets inside the oil box 300 continue to gather, the suspension 311 will float on the rising oil surface under the action of buoyancy, driving the oil level prompt line 312 to rise to remind the user to deal with the oil inside the oil box 300 in time.
[0044] Example 2
[0045] This embodiment discloses a range hood, which includes:
[0046] The hood body is used to store and discharge the oil smoke sucked by the range hood fan, and its lower surface is provided with an air inlet channel 100 and an oil collection assembly 200 for collecting oil droplets. Usually, the lower surface of the hood body is installed just above the stove to collect the oil smoke and condensed water vapor generated during cooking.
[0047] Specifically, in this embodiment, the oil collecting assembly 200 includes an oil receiving member 210, and two groups of guide groove groups distributed on both sides of the central axis of the oil receiving member 210; the guide groove group includes a plurality of guide grooves 220 arranged in an array along the width direction of the lower surface of the hood body, and the guide groove 220 is provided with an oil outlet 221; the oil receiving member 210 includes a mounting portion 211 for fixing on the lower surface of the hood body, and an oil groove 212 mirror-set on both sides of the mounting portion 211; the oil groove 212 is tilted along the width direction of the lower surface of the hood body, and is used to receive the oil droplets of the guide groove oil outlet 221 in the guide groove group and transmit it to the discharge end of the oil receiving member. In this embodiment, by making a special design for the docking oil member 210 - mirror-setting the oil grooves along both sides of the mounting portion 211, the technical problem of limited designable area of the air inlet channel 100 caused by the excessive area occupied by the oil receiving member 210 on the lower surface of the hood body, or even blocking the amount of smoke in the air inlet channel 100, which causes the range hood to have a poor oil fume absorption effect. In addition, since the air inlet channel 100 in this embodiment is arranged on the lower surface of the hood body, the oil smoke will rise to the lower surface of the hood body under the action of the fan, so the oil smoke collection burden at this position is relatively greater. The above design of the oil receiving member 210 can also reduce the contact area between the oil receiving member 210 and the oil smoke, and reduce the formation of oil droplets on the outer wall of the oil receiving member 210. Further, in this embodiment, the oil receiving member 210 is inclined and is made of an oleophobic material. Therefore, although oil droplets are formed on its outer wall, they can still slide down along the inclined oil receiving member 210 to the designated oil drop collection position.
[0048] In this embodiment, the lower surface of the hood body is horizontally arranged, and only the oil groove 212 is arranged obliquely along the width direction of the lower surface of the hood body. In this situation, in order to realize the oil guiding function of the guide groove 220, the guide groove 220 is arranged parallel to the length direction of the lower surface of the hood body, and is a special-shaped part arranged on the lower surface of the hood body. The so-called special-shaped part specifically refers to a protruding arrangement obliquely downward along the direction of the oil outlet 211 of the guide groove.
[0049] In this embodiment, along the length direction of the lower surface of the hood body, the oil collecting assembly 200 array is arranged in two groups, and the air inlet channel 100 is arranged between two adjacent oil collecting assemblies 200. Of course, this kind of range hood is more suitable for the oil fume treatment of a single stove. In order to solve the technical problem of poor oil droplet collection effect at the position of the air inlet channel 100 caused by the simultaneous arrangement of the air inlet channel 100 and the guide groove 220 on the lower surface of the hood body, in this embodiment, an inclined surface for transferring oil droplets from the air inlet channel 100 to the guide groove 220 is formed between the air inlet channel 100 and the two adjacent oil collecting assemblies 200. Therefore, the oil droplets condensed around the air inlet channel opening can slide along the inclined surface to the vicinity of the guide groove 220, and finally enter the interior of the guide groove 220, and flow along the guide groove 220 to the guide groove oil outlet 221.
[0050] In order to shorten the residence time of oil stains in the oil guide groove 220 and the oil groove 212, the length of the guide groove 220 is 7 cm, and of course it can also be selected from 4 to 7 cm in other embodiments; the horizontal height difference between the oil outlet 221 of the guide groove and the lowest point of the oil receiving member oil groove 212 is 5 cm, and of course it can also be selected from 2 to 5 cm in other embodiments. In this embodiment, by adjusting the length of the guide groove 220 itself, the weight of the oil droplets can be controlled. Further, by designing the horizontal height difference between the oil outlet of the guide groove and the lowest point of the oil receiving member oil groove 212, the potential energy difference of the falling process of oil droplets of a specific weight can be effectively utilized to regulate the flow speed of the oil droplets in the oil groove 212, and reduce the residence time of the oil droplets on the inner wall of the oil groove 212, thereby improving the collection efficiency of the oil droplets and reducing the difficulty and frequency of daily maintenance of the oil receiving member 210.
[0051] In order to increase the convenience of cleaning the lower surface of the air hood body, the oil collecting piece mounting portion 211 in this embodiment is slidably connected to the lower surface of the air hood body, and the lower end of the mounting portion 211 is mirror-imaged outward with the mounting portion 211 as the axis to form an open C-shaped piece, and the oil groove 212 is formed inside the C-shaped piece. The oil groove is open upward and is used to receive oil droplets flowing out of the oil outlet portion 221 of the guide groove.
[0052] The oil box 300 is used to receive the oil droplets flowing out of the discharge end of the oil receiving piece. In order to ensure that the oil droplets collected through the oil guide groove 220 can be smoothly transferred from the oil outlet of the guide groove to the oil box 300, reduce the risk of oil droplets suspended in the air or splashing around, and improve the safety of the system, a connecting surface 400 is also provided in this embodiment. Specifically, the connecting surface 400 is an arc-shaped plate, which is connected to the end away from the user with the lower surface of the inclined wind hood body, and the connecting surface 400 is connected to the discharge end of the oil receiving piece of the three groups of oil collection components 200. Therefore, as the amount of oil in the internal oil groove 212 of the oil receiving piece 210 continues to increase, the oil will flow from the discharge end of the oil receiving piece to the connecting surface 400, and then under the guidance of the connecting surface 400, it will flow into the oil box 300.
[0053] Considering that the oil droplet collection efficiency of the oil box 300 is higher than that of the existing range hood with a longitudinal integrated oil guide groove, in order to avoid safety problems caused by overflow when the oil inside the oil box reaches a certain volume, an oil volume reminder component 310 for reminding the oil volume of the oil box is also provided inside the oil box 300 of the present embodiment. Specifically, the oil volume reminder component 310 includes a suspension 311 slidably connected to the inner wall of the oil box 300; the suspension 311 is provided in two groups; the oil volume reminder component 310 also includes an oil volume reminder line 312 fixedly arranged between the suspensions 311; the oil volume reminder line 312 can be in eye-catching colors such as red, yellow or green to achieve a better oil volume reminder effect.
[0054] During the use of the range hood disclosed in this embodiment, the oil smoke rises to the lower surface of the hood body under the negative pressure of the fan. At this time, most of the oil smoke will enter the hood body through the air inlet channel 100 to achieve the collection and discharge of the oil smoke. However, at the same time, some of the oil smoke will liquefy and form oil droplets on the lower surface of the hood body when it contacts the low-temperature materials such as the lower surface of the hood body. Specifically, the hood body of this application is made of oleophobic material, and the oil droplets condensed around the air inlet channel can slide along the inclined surface to the vicinity of the guide groove 220, and finally enter the guide groove 220. Further, the oil droplets on the guide groove 220 will flow to the oil outlet portion 221 of the guide groove 220 under the action of gravity along the direction of the oil outlet portion 221 of the guide groove 220, and then drip into the oil groove 212 of the oil receiving member. Inside the same oil collection component 200, the oil droplets dripping at different positions will continuously flush the inner wall of the oil groove 212, driving the oil droplets to flow quickly to the discharge end of the oil groove. Finally, based on the connection relationship between the connection surface 400 and the discharge end, when the oil droplets at the discharge end gather to a certain extent, the oil will flow along the connection surface 400 to the inside of the oil box 300 to complete the collection of oil smoke. As the oil droplets inside the oil box 300 continue to gather, the suspension 311 will float on the rising oil surface under the action of buoyancy, driving the oil level prompt line 312 to rise to remind the user to deal with the oil inside the oil box 300 in time.
