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 first oil guiding surface for being arranged above a stove top, a second oil guiding surface for being arranged in front of the stove top, and an oil box arranged at one end of the second oil guiding surface away from the first oil guiding surface; at least two groups of oil collecting components are arranged on the first oil guiding surface, and the oil collecting components include a guide groove group and an oil receiving piece; the guide groove group includes a plurality of groups of guide grooves, and the guide grooves are provided with an oil outlet; the oil receiving piece includes an oil groove arranged obliquely; the oil groove is used to receive oil droplets at the oil outlet of the guide groove in the guide groove group and transmit it to the discharge end of the oil receiving piece; the second oil guiding surface is provided with an air inlet channel.

[0007] Preferably, in the same guide groove group, the guide grooves are arranged in an array along the width direction of the oil guide surface.

[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 of the first oil guide surface with a smaller size, that is, the wide side of the rectangle, but it does not exclude specific circumstances, such as a specific model of a single-stove range hood, which corresponds to the side of the first oil guide surface with a larger size, 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 first oil guide surface at a completely consistent angle or even the same structure, as long as the oil droplets at the oil outlet ends of several guide grooves in the same guide groove group can drip into the same oil groove to achieve the research and development purpose. The end of the first oil guide surface away from the user is connected to the upper end of the second oil guide surface.

[0009] Preferably, the air inlet channel is arranged at one end of the second oil guide surface close to the oil box; and an oil net is arranged on the air inlet channel.

[0010] Preferably, the second oil guiding surface is connected to the first oil guiding surface at one end away from the oil box via an arc-shaped connecting plate; the arc-shaped connecting plate is connected to the discharge end of the oil receiving piece.

[0011] Preferably, an oil collecting groove whose lower end is connected to the oil net is also longitudinally arranged on the second oil guide surface.

[0012] Preferably, the length of the guide groove is between 2 and 10 cm; the horizontal height difference between the oil outlet of the guide groove and the lowest point of the oil tank of the oil receiving part is 1 to 8 cm. Further preferably, the length of the guide groove is between 4 and 7 cm; the horizontal height difference between the oil outlet of the guide groove and the lowest point of the oil tank of the oil receiving part is 2 to 5 cm.

[0013] Preferably, the first oil guide surface is arranged parallel to the oil groove, and the angle between the oil outlet direction of the guide groove and the downward inclined direction of the oil groove is 5-85°. Further preferably, the first oil guide surface is arranged parallel to the oil groove, and the angle between the oil outlet direction of the guide groove and the downward inclined direction of the oil groove is 30-60°.

[0014] Preferably, the first oil guiding surface is arranged horizontally; and the guide groove is arranged to protrude downwardly from the first oil guiding surface along the oil outlet direction of the guide groove.

[0015] Preferably, an oil level reminder component for reminding the oil level of the oil box is provided inside the oil box.

[0016] Preferably, the oil level reminder assembly includes a suspension member slidably connected to the inner wall of the oil box.

[0017] 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.

[0018] Compared with the prior art, this application has the following beneficial effects:

[0019] The present application arranges an oil collecting component on the first oil guide surface and an air inlet channel on the second oil guide surface. The air inlet channel can absorb the oil fume well; the oil collecting component can collect the oil droplets above the stove; the interference between the oil fume absorption and oil droplet collection functions caused by the air inlet channel being arranged on the first oil guide surface can be effectively avoided, thereby improving the working efficiency and cleaning effect of the overall device and providing users with a more comfortable and clean cooking environment.

[0020] The present application arranges at least two groups of oil collecting components on the first oil guide surface, 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 groove, thereby avoiding excessive stay of oil stains on the surface of the guide groove to form wall-hanging oil stains, and the first oil guide surface is easier to clean.

[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] By setting an oil collection groove on the second oil guide surface, the present application can not only collect the oil droplets condensed above the air inlet channel, but also cooperate with the oil collection assembly on the first oil guide surface and even the arc-shaped connecting plate to achieve all-round collection of oil smoke above the stove. Specifically, the first oil guide surface, the second oil guide surface and the arc-shaped connecting plate can not only independently guide and collect the liquefied oil droplets formed on their surfaces, but also ensure that these oil droplets are collected together through mutual cooperation to achieve a more efficient oil fume management effect. This design optimizes the oil fume treatment process and helps to improve the cleanliness of the kitchen environment.

[0023] The arc-shaped connecting plate of the present application can connect the discharge end of the oil receiving piece with the second oil guide surface. In this way, the oil droplets flowing out from the discharge end of the oil receiving piece can smoothly flow into the oil collecting groove through the arc-shaped connecting plate, and finally enter the oil box through the oil net along a preset path, thereby realizing efficient collection and management of oil droplets and keeping the kitchen environment clean.

[0024] The present application can control the weight of the oil droplets by adjusting the length of the guide groove itself, and further by designing 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, it can effectively utilize the potential energy difference in 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 sets the first oil guide surface parallel to the oil tank and at a certain tilt angle, and reasonably adjusts the direction of the oil outlet of the guide groove to form a suitable angle with the tilted downward direction of the oil tank. In this way, on the one hand, gravity can be fully utilized as the main power source for oil conduction, making the design of the guide groove more concise and efficient; on the other hand, under the same first oil guide surface condition, the number of guide grooves is increased to meet the oil conduction demand under high oil smoke conditions, thereby ensuring that the oil smoke can be promptly and effectively guided to the collection device, improving the overall oil conduction efficiency and practicality of the system. This improvement not only simplifies the structure, but also enhances the reliability and flexibility of the system under complex use conditions.

[0026] The oil level reminder component in this application is provided by setting two groups of suspension parts, and fixing the oil level reminder line between the two groups of suspension parts. By utilizing the buoyancy of the suspension parts on the surface of the oil, as the amount of oil in the oil box increases, the suspension parts will rise and drive the oil level reminder line to move up together. When the oil reaches a certain volume and the oil level reminder line reaches the preset warning position, the component will promptly remind the user that the oil needs to be handled to prevent the oil from being overfilled and overflowing, thereby avoiding possible safety problems caused by this. This design not only simplifies the process of oil level monitoring, but also effectively ensures the safety of use and improves the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The present application will be further described below in the form of specific embodiments. A person 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.

The directional terms such as upper, lower, left, right, front, rear, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings, and the words "inside" and "outside" refer to the direction toward or away from the geometric center of a specific component, respectively. They are relative concepts, and therefore may change accordingly according to their different positions and different usage states. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0034] Example 1

[0035] This embodiment discloses a range hood, which includes:

[0036] The L-shaped air hood body includes a first oil guiding surface 100 for being arranged above the stove, a second oil guiding surface 200 for being arranged in front of the stove, and an arc-shaped connecting plate 400 for connecting the lower end of the first oil guiding surface 100 and the upper end of the second oil guiding surface 200.

[0037] Along the length direction of the first oil guiding surface 100, 9 groups of oil collecting components 110 are arranged in an array on the first oil guiding surface 100, and the oil collecting components 110 include a guide groove group and an oil receiving piece 111; the guide groove group includes a plurality of guide grooves 112 arranged in an array along the width direction of the first oil guiding surface 100, and the guide grooves 112 are provided with oil outlets; the oil receiving piece 111 includes an oil groove arranged obliquely; the oil groove is used to receive oil droplets from the oil outlet of the guide groove 112 in the guide groove group and transmit it to the discharge end of the oil receiving piece 111; the discharge end of the oil receiving piece 111 is connected to the arc-shaped connecting plate 400.

[0038] Specifically, in order to simplify the structural design of the guide groove 112, in this embodiment, the first oil guide surface 100 is arranged in parallel with the inclined oil groove, that is, the first oil guide surface 100 is arranged obliquely. More specifically, along the direction away from the user, the first oil guide surface 100 and the oil groove are arranged obliquely downward. Further, the oil guide groove 112 is a groove arranged on the first oil guide surface 100, and the angle between the oil outlet direction of the oil guide groove 112 and the oblique downward direction of the oil groove is 50°. Of course, it can be understood that in other embodiments, this angle can also be selected from the range of 5~85°. Through the design of the first oil guide surface 100 and the inclined oil groove, the oil guide groove 112 can realize oil conduction by the action of gravity, without the need for special structural design, and reducing the difficulty of cleaning the special-shaped parts on the surface of the first oil guide surface 100. In addition, the inclined guide groove 112 can arrange more guide channels on the same first oil guide surface 100, thereby increasing the collection area of ​​oil droplets and improving the collection efficiency of oil droplets. In this way, even if a large amount of oil smoke is generated during the cooking process, it can ensure that the oil droplets are effectively guided to the collection device, reducing the spread of oil smoke in the kitchen and improving the overall oil conduction performance.

[0039] In this embodiment, the oil receiving member 111 is a C-shaped member, and a mounting portion for sliding and detachably connecting with the first oil guide surface 100 is formed at the upper end of the C-shaped member, and the internal groove at the lower end of the C-shaped member forms the oil groove. Therefore, during the maintenance and cleaning process, it is only necessary to slide and disassemble the oil receiving member 111 and clean the first oil guide surface 100 and the oil receiving member 111 respectively, and the cleaning work becomes more convenient. In order to shorten the residence time of oil stains in the oil guide groove 112 and the oil groove, the length of the guide groove 112 is 5 cm, and the horizontal height difference between the oil outlet of the guide groove and the lowest point of the oil groove of the oil receiving member is 1 cm. Of course, it can be understood that in other embodiments, the length of the guide groove 112 can also be selected from 2 to 10 cm, and the horizontal height difference between the oil outlet of the guide groove and the lowest point of the oil groove of the oil receiving member can also be selected from 1 to 8 cm. By adjusting the length of the guide groove 112 itself, controlling the weight of the oil droplets, and designing 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, the potential energy difference during 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, 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.

[0040] Along the longitudinal direction, the second oil guide surface 200 is tilted, and the surface thereof is provided with an oil collection groove 220 and an air inlet channel 210 in sequence from top to bottom. The oil collection groove 220 is a groove provided on the second oil guide surface 200; an oil net is provided on the air inlet channel 210; the lower end of the groove is connected to the upper end of the oil net. Furthermore, the oil collection groove 220 and the oil receiving member 111 are provided in 9 groups correspondingly, so the oil droplets flowing out from the discharge end of the oil receiving member 111 will flow into the oil collection groove 220 through the arc-shaped connecting plate 400, and finally flow along the oil collection groove 220 to the oil net installed on the air inlet channel 210 under the action of gravity.

[0041] The oil box 300 is arranged at the end of the second oil guide surface 200 away from the first oil guide surface 100. Specifically, the upper end of the oil box 300 is connected to the lower surface of the air inlet channel 210. The oil box 300 is used to store the oil dripping from the oil net. Considering that the oil box 300 of this embodiment has a higher oil drop collection efficiency than the existing range hood with a longitudinal integrated oil guide groove, in order to avoid the safety problem caused by the overflow of the oil in the oil box when the oil reaches a certain volume, the oil box 300 of this embodiment is also provided with an oil quantity reminder component 310 for indicating the oil storage amount of the oil box. Specifically, the oil quantity reminder component 310 includes a suspension 311 slidably connected to the inner wall of the oil box 300; the suspension 311 is arranged in two groups; the oil quantity reminder component 310 also includes an oil quantity reminder line 312 fixedly arranged between the suspensions 311; the oil quantity reminder line 312 can be in a striking color such as red, yellow or green to achieve a better oil quantity reminder effect. The other components and structural design of the range hood disclosed in this embodiment adopt the existing technology and will not be repeated in this part.

[0042] During the use of the range hood disclosed in this embodiment, under the negative pressure of the fan, most of the rising oil smoke will diffuse into the interior of the L-shaped hood body through the oil net and the air inlet channel 210, and will be discharged to the outdoor or corridor oil smoke duct through the air duct 500 provided at the upper end of the L-shaped hood body. The oil droplets condensed on the first oil guide surface 100 flow toward the oil outlet along the guide groove 112 under the action of gravity, and then drip into the oil tank of the oil receiving part. Inside the same oil collection component 110, the oil droplets dripping at different positions will continuously flush the inner wall of the oil tank, driving the oil droplets to flow quickly to the discharge end of the oil tank. 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 collection groove 220, and finally flow along the oil collection groove 220 to the oil net installed on the air inlet channel 210 under the action of gravity, and drip into the oil box 300 through the oil net to complete the collection of the oil. 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.

[0043] Example 2

[0044] This embodiment discloses a range hood, which includes:

[0045] The L-shaped air hood body includes a first oil guiding surface 100 for being arranged above the stove, a second oil guiding surface 200 for being arranged in front of the stove, and an arc-shaped connecting plate 400 for connecting the lower end of the first oil guiding surface 100 and the upper end of the second oil guiding surface 200.

[0046] Along the length direction of the first oil guide surface 100, 5 groups of oil collection components 110 are arranged in an array on the first oil guide surface 100, and the oil collection components 110 include a guide groove group and an oil receiving member 111; the guide groove group includes 10 groups of guide grooves 112 arranged in an array along the width direction of the first oil guide surface 100, and the guide groove 112 is provided with an oil outlet; the oil receiving member 111 includes an oil groove arranged obliquely, and the oil groove is designed to be inclined downward in the direction away from the user; the oil groove is used to receive the oil droplets from the oil outlet of the guide groove 112 in the guide groove group and transmit it to the discharge end of the oil receiving member 111; the discharge end of the oil receiving member 111 is connected to the arc-shaped connecting plate 400. Specifically, in this embodiment, the first oil guide surface 100 is arranged horizontally. In this situation, in order to realize the oil guiding function of the guide groove 112, the guide groove 112 is arranged to protrude downward along the direction of the oil outlet of the guide groove.

Therefore, during the maintenance and cleaning process, it is only necessary to slide and disassemble the oil receiving member 111 and clean the first oil guide surface 100 and the oil receiving member 111 respectively, and the cleaning work becomes more convenient. In order to shorten the residence time of oil stains in the oil guide groove 112 and the oil groove, the length of the guide groove 112 is 7 cm, and the horizontal height difference between the oil outlet of the guide groove and the lowest point of the oil groove of the oil receiving member is 2 cm. Of course, it can be understood that in other embodiments, the length of the guide groove 112 can also be selected from 4 to 7 cm, and the horizontal height difference between the oil outlet of the guide groove and the lowest point of the oil groove of the oil receiving member can also be selected from 2 to 5 cm. By adjusting the length of the guide groove 112 itself, controlling the weight of the oil droplets, and designing 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, the potential energy difference during 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, 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.

[0048] Along the longitudinal direction, the second oil guide surface 200 is tilted, and the surface thereof is provided with an oil collection groove 220 and an air inlet channel 210 in sequence from top to bottom. The oil collection groove 220 is a special-shaped part provided on the second oil guide surface 200; an oil net is provided on the air inlet channel 210; the lower end of the groove is connected to the upper end of the oil net. Furthermore, the oil collection groove 220 and the oil receiving member 111 are provided in 5 groups correspondingly, so the oil droplets flowing out from the discharge end of the oil receiving member 111 will flow into the oil collection groove 220 through the arc-shaped connecting plate 400, and finally flow along the oil collection groove 220 to the oil net installed on the air inlet channel 210 under the action of gravity.

[0049] The oil box 300 is arranged at the end of the second oil guide surface 200 away from the first oil guide surface 100. Specifically, the upper end of the oil box 300 is connected to the lower surface of the air inlet channel 210. The oil box 300 is used to store the oil dripping from the oil net. Considering that the oil box 300 has a higher oil drop collection efficiency than the existing range hood with a longitudinal integrated oil guide groove 112, in order to avoid the safety problem caused by the overflow of the oil in the oil box when the oil reaches a certain volume, the oil box 300 of this embodiment is also provided with an oil quantity reminder component 310 for indicating the oil storage amount of the oil box. Specifically, the oil quantity reminder component 310 includes a suspension 311 slidably connected to the inner wall of the oil box 300; the suspension 311 is set in two groups; the oil quantity reminder component 310 also includes an oil quantity reminder line 312 fixedly arranged between the suspensions 311; the oil quantity reminder line 312 can be in a striking color such as red, yellow or green to achieve a better oil quantity reminder effect. The other components and structural design of the range hood disclosed in this embodiment adopt the existing technology and will not be repeated in this part.

[0050] During the use of the range hood disclosed in this embodiment, under the negative pressure of the fan, most of the rising oil smoke will diffuse into the interior of the L-shaped hood body through the oil net and the air inlet channel 210, and will be discharged to the outdoor or corridor oil smoke duct through the air duct 500 provided at the upper end of the L-shaped hood body. The oil droplets condensed on the first oil guide surface 100 flow toward the oil outlet along the guide groove 112 under the action of gravity, and then drip into the oil tank of the oil receiving part. Inside the same oil collection component 110, the oil droplets dripping at different positions will continuously flush the inner wall of the oil tank, driving the oil droplets to flow quickly to the discharge end of the oil tank. 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 collection groove 220, and finally flow along the oil collection groove 220 to the oil net installed on the air inlet channel 210 under the action of gravity, and drip into the oil box 300 through the oil net to complete the collection of the oil.
