Description

Technical Field

[0001] This invention relates to the field of kitchenware, and more particularly to a range hood. Background Technology

[0002] The main function of a range hood is to quickly expel cooking fumes outdoors. To achieve this, it's usually necessary to increase the airflow rate of the range hood per unit time. The air intake structure of a range hood typically consists of a mesh grille and a condenser plate. Increasing the airflow often leads to higher noise levels. Larger airflow usually requires a larger air intake area, which can result in an unsightly design and difficulty in controlling the grease trap.

[0003] In related technologies, range hoods are typically designed with a single duct structure, primarily drawing in air through a separate duct below the fan. However, a single duct can only enhance the smoke extraction effect by increasing airflow, and cannot further optimize the extraction effect based on the specific location of the smoke. Furthermore, the single duct design has limited functionality; users can only adjust the range hood's settings by changing the fan's power, resulting in fewer settings and functions. In addition, range hoods in related technologies draw in smoke directly from below, and due to the position of the cooktop relative to the range hood and the diffusion of smoke as it rises, this method of smoke extraction is often ineffective. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a range hood that can increase the air intake area of ​​the range hood, making the range hood's smoke extraction effect better and more efficient. Furthermore, while retaining the negative pressure expansion on the left and right sides, it increases the effective air intake at the front, reducing the risk of smoke condensation and dripping from the front, and also preventing smoke escape, thus ensuring the range hood's smoke extraction performance.

[0008] According to embodiments of the present invention, the range hood with three air inlets (unless otherwise specified, an air inlet refers to at least one of the first, second, and third air inlets) can increase the air intake area of ​​the range hood. Furthermore, the three air inlets located at different positions can draw fumes from different locations into the range hood, resulting in better and more efficient fume extraction. In addition, while retaining the negative pressure expansion on the left and right sides, the effective air intake at the front is increased, reducing the risk of condensation and dripping of fumes from the front.

[0053] The following description of a range hood according to an embodiment of the present invention is with reference to the accompanying drawings.

[0054] like Figures 1 to 15 As shown, the range hood according to an embodiment of the present invention includes a body 1, the body 1 having a smoke chamber 11, and the bottom of the body having a first air inlet 12, a second air inlet 13 and a third air inlet 14 communicating with the smoke chamber 11. The first air inlet 12 and the second air inlet 13 are opposite to each other and at an angle, and the third air inlet 14 is located in front of the first air inlet 12 and the second air inlet 13. The bottom of the body 1 is also provided with a first guide wall 101, a second guide wall 102 and a third guide wall 103. The first guide wall 101 is opposite to the first air inlet 12 and at an angle, the second guide wall 102 is opposite to the second air inlet 13 and at an angle, and the third guide wall 103 is opposite to the third air inlet 14 and at an angle.

[0055] According to the embodiments of the present invention, the range hood with three air inlets (unless otherwise specified, the air inlet refers to at least one of the first air inlet 12, the second air inlet 13, and the third air inlet 14) can increase the air intake area of ​​the range hood. Furthermore, the three air inlets located at different positions can draw oil fumes from different positions into the range hood, resulting in better and more efficient oil fume extraction. In addition, while retaining the negative pressure expansion on the left and right sides, the effective air intake at the front is increased, reducing the risk of oil fume condensation and dripping from the front. Moreover, the first guide wall 101, the second guide wall 102, and the third guide wall 103 can guide the oil fumes, preventing them from escaping and ensuring the oil fume extraction performance of the range hood.

[0056] like Figure 3 As shown, according to an embodiment of the present invention, the first air inlet 12 and the second air inlet 13 are respectively located on the left and right sides of the bottom of the body 1, the third air inlet 14 is located on the front side of the bottom of the body 1, the first guide wall 101 is located on the left side of the first air inlet 12, the second guide wall 102 is located on the right side of the second air inlet 13, and the third guide wall 103 is located on the front side of the third air inlet 14.

[0057] Among them, such as Figure 7 As shown, on a vertical plane perpendicular to the front-to-back direction, the projections formed by the first guide wall 101, the first air inlet 12, the second air inlet 13, and the second guide wall 102 together constitute an M-shape. On a vertical plane perpendicular to the left-to-right direction, the projections formed by the third guide wall 103 and the third air inlet 14 together constitute a downward-opening trumpet shape.

[0058] The first air inlet 12, the second air inlet 13, and the third air inlet 14 can be kept open to make it more convenient for users to use the range hood.

[0059] According to one embodiment of the present invention, the bottom of the body 1 is provided with a mounting frame, which includes a first frame strip, a second frame strip, and a third frame strip. The first frame strip is located between the first air inlet 12 and the third air inlet 14, the second frame strip is located between the first air inlet 12 and the second air inlet 13, and the third frame strip is located between the second air inlet 13 and the third air inlet 14. The mounting frame is Y-shaped. In this way, the air intake area of ​​the first air inlet 12, the second air inlet 13, and the third air inlet 14 can be maximized, thereby maximizing the air intake volume within a limited space.

[0060] In one embodiment of the invention, the angle between the second frame strip and the horizontal plane is 6° to 30°. This inclined second frame strip guides the condensed oil, preventing it from dripping directly into the cookware below the range hood and ensuring a better user experience. For example, the angle between the second frame strip and the horizontal plane is 11°.

[0061] According to one embodiment of the present invention, the range hood further includes: a first air mesh 5, a second air mesh 6, and a third air mesh 7. The first air mesh 5 is installed between the first frame strip and the second frame strip, the second air mesh 6 is installed between the second frame strip and the third frame strip, and the third air mesh 7 is installed between the third frame strip and the first frame strip. The mounting frame and the body 1 are integrally formed. This simplifies the manufacturing of the first air mesh 5, the second air mesh 6, and the third air mesh 7, and their planar configuration facilitates cleaning. The manufacturing and assembly of the mounting frame are also more convenient.

[0062] like Figure 15 As shown, according to one embodiment of the present invention, oil guiding holes are formed on the first air mesh 5, the second air mesh 6, and the third air mesh 7, respectively. Each side of the oil guiding hole extends along the direction towards the oil cup 4 of the range hood. In this way, oil droplets can flow towards the oil cup 4 along the oil guiding hole under the action of gravity. The oil guiding hole has the function of guiding the condensed oil in the direction of flow. For example, the oil cup 4 is located on the rear side of the bottom of the body 1, and the oil guiding hole is hexagonal or elongated, with each side of the oil guiding hole extending rearward (i.e., towards the oil cup 4).

[0063] like Figure 10 As shown, according to one embodiment of the present invention, the angle between the third air inlet 14 and the third guide wall 103 is 85° to 115°. Thus, the funnel-like converging structure formed by the third air inlet 14 and the third guide wall 103 can more efficiently collect oil fumes, resulting in higher oil fume extraction efficiency of the range hood. For example, the angle between the third air inlet 14 and the third guide wall 103 is 100°.

[0064] like Figure 6 As shown, according to one embodiment of the present invention, the width of the third air inlet 14 gradually increases from bottom to top. This allows the third air inlet 14 to maximize its ventilation area within a limited space, resulting in a larger overall fume extraction area for the range hood.

[0065] like Figure 5 As shown, according to one embodiment of the present invention, the first air inlet 12 and the second air inlet 13 are symmetrically arranged quadrilateral openings, and the third air inlet 14 is a trapezoidal opening. In this way, the ventilation area of ​​the first air inlet 12, the second air inlet 13 and the third air inlet 14 can be increased, and it is also beneficial for oil drainage.

[0066] According to one embodiment of the present invention, the angle between the first air inlet 12 and the second air inlet 13 is greater than or equal to 145° and less than 180°. This further ensures the range hood's smoke extraction efficiency.

[0067] like Figure 6As shown, according to one embodiment of the present invention, the bottom of the body 1 is provided with a mounting platform 15. The mounting platform 15 includes a first sidewall forming a first air inlet 12, a second sidewall forming a second air inlet 13, a third sidewall forming a third air inlet 14, and a bottom surface connecting the first sidewall, the second sidewall, and the third sidewall. The first sidewall, the second sidewall, and the third sidewall all slope downwards towards the bottom surface. In this way, by placing the first air inlet 12, the second air inlet 13, and the third air inlet 14 on the downwardly protruding mounting platform 15, the oil fume extraction efficiency of the range hood can be further guaranteed.

[0068] like Figure 6 As shown, according to one embodiment of the present invention, the range hood further includes an oil cup 4, which is adapted to store condensed oil and is disposed at the bottom of the body 1, located below the rear side of the mounting platform 15; the first side wall, the second side wall, the third side wall, and the bottom surface are inclined downwards and backwards. This allows the condensed oil to be guided into the oil cup 4, preventing it from dripping from the range hood and affecting the user's use.

[0069] like Figure 1 As shown, according to one embodiment of the present invention, it further includes: a first condensing plate 2 and a second condensing plate 3.

[0070] The first condenser plate 2 is correspondingly arranged with the first air inlet 12, and has a first end and a second end arranged opposite to it. The second end of the first condenser plate 2 is adapted to rotate around its first end to switch between the open position of opening the first air inlet 12 and the closed position of closing the first air inlet 12.

[0071] The second condenser plate 3 is correspondingly arranged with the second air inlet 13, and has a first end and a second end arranged opposite to it. The second end of the second condenser plate 3 is adapted to rotate around its first end to switch between the open position of the second air inlet 13 and the closed position of the second air inlet 13; wherein the opening directions of the first condenser plate 2 and the second condenser plate 3 are opposite.

[0072] In this way, by setting the opening directions of the first condensing plate 2 and the second condensing plate 3 in opposite directions, the fumes can be drawn into the first air inlet 12 and the second air inlet 13 along the side of the range hood, thus changing the fume extraction method of the range hood to a side-suction type. Since the fumes will diffuse during the rising process, the side-suction type range hood has a better fume extraction effect, thereby greatly optimizing the fume extraction method of the range hood. In addition, by integrating the normally open third air inlet 14 with the controllable first air inlet 12 and the second air inlet 13 into the range hood, more speed settings and functions can be generated. Users can select different speed settings of the range hood according to the actual situation, thereby expanding the applicability of the range hood.

[0073] According to one embodiment of the present invention, when a mounting platform 15 is provided at the bottom of the body 1, the first condensing plate 2 and the mounting platform 15 overlap in the closed position of the first condensing plate 2; and the second condensing plate 3 and the mounting platform 15 overlap in the closed position of the second condensing plate 3. This prevents condensed oil from dripping from the first condensing plate 2 and the second condensing plate 3, and also improves the aesthetics of the structure. For example, the first condensing plate 2 and each side of the first sidewall of the mounting platform 15 are overlapped, and the second condensing plate 3 and each side of the second sidewall of the mounting platform 15 are overlapped.

[0074] The following description, with reference to the accompanying drawings, describes a range hood according to other embodiments of the present invention.

[0075] like Figures 1 to 15 As shown, the range hood according to an embodiment of the present invention includes: a body 1, a first condenser plate 2, and a second condenser plate 3.

[0076] The body 1 has a smoke chamber 11, and its bottom has a first air inlet 12, a second air inlet 13, and a third air inlet 14 communicating with the smoke chamber 11. A first condenser plate 2 is correspondingly arranged with the first air inlet 12, having a first end and a second end arranged opposite to it. The second end of the first condenser plate 2 is adapted to rotate around its first end to switch between an open position with the first air inlet 12 open and a closed position with the first air inlet 12 closed. A second condenser plate 3 is correspondingly arranged with the second air inlet 13, having a first end and a second end arranged opposite to it. The second end of the second condenser plate 3 is adapted to rotate around its first end to switch between an open position with the second air inlet 13 open and a closed position with the second air inlet 13 closed. The opening directions of the first condenser plate 2 and the second condenser plate 3 are opposite to each other.

[0077] According to an embodiment of the present invention, the range hood with three air inlets (unless otherwise specified, an air inlet refers to at least one of the first air inlet 12, the second air inlet 13, and the third air inlet 14) can increase the air intake area of ​​the range hood. Furthermore, the three air inlets located at different positions can draw fumes from different locations into the range hood, resulting in better and more efficient fume extraction. On the other hand, by arranging the opening directions of the first condenser plate 2 and the second condenser plate 3 in opposite directions, fumes can be drawn along the side of the range hood... The fumes are drawn into the first air inlet 12 and the second air inlet 13, thus changing the fume extraction method of the range hood to a side-suction type. Since the fumes diffuse during the upward process, the side-suction type range hood has a better fume extraction effect, which greatly optimizes the fume extraction method of the range hood. In addition, by integrating the normally open third air inlet 14 with the controllable first air inlet 12 and second air inlet 13 into the range hood, more speed settings and functions can be generated. Users can select different speed settings of the range hood according to the actual situation, thereby expanding the applicability of the range hood.

[0078] According to an embodiment of the present invention, the bottom of the body 1 is formed with a first air inlet 12, a second air inlet 13, and a third air inlet 14 opening downwards. It can be understood that the "bottom of the body 1" refers to the portion of the body 1 facing the stove when the user uses the range hood. The first air inlet 12, the second air inlet 13, and the third air inlet 14 are three independent air inlets. The first air inlet 12, the second air inlet 13, and the third air inlet 14 can be positioned in different ways to adapt to different oil fume conditions. For example, the first air inlet 12, the second air inlet 13, and the third air inlet 14 can be respectively positioned corresponding to the stove below the range hood; the first air inlet 12, the second air inlet 13, and the third air inlet 14 can also be positioned relative to each other in the left, right, and front directions; the first air inlet 12, the second air inlet 13, and the third air inlet 14 can also be arranged side-by-side on the same horizontal plane. Of course, the positions of the first air inlet 12, the second air inlet 13 and the third air inlet 14 are not limited to this. This embodiment of the invention does not make any special limitation here, as long as the bottom of the body 1 can form the first air inlet 12, the second air inlet 13 and the third air inlet 14.

[0079] According to an embodiment of the present invention, the first air inlet 12 can be in the shape of a triangle, rectangle, ellipse, circle, trapezoid, pentagon, hexagon, etc. The shapes of the second air inlet 13 and the third air inlet 14 can also be the shapes listed above for the first air inlet 12. The shapes of the first air inlet 12, the second air inlet 13, and the third air inlet 14 can be all the same, partially the same, or all different. Of course, the shapes of the first air inlet 12, the second air inlet 13, and the third air inlet 14 are not limited to these. The present invention does not make any special limitations here, as long as the first air inlet 12, the second air inlet 13, and the third air inlet 14 can all realize the function of air intake.

[0080] According to an embodiment of the present invention, "the first condenser plate 2 is correspondingly arranged with the first air inlet 12" means that the first condenser plate 2 is positioned to open or close the first air inlet 12 by a flipping action; the installation position of the second condenser plate 3 is similar to that of the first condenser plate 2, for example, the first condenser plate 2 is located below the first air inlet 12, and the second condenser plate 3 is located below the second air inlet 13. The phrase "the opening directions of the first condenser plate 2 and the second condenser plate 3 are opposite" means that the opening action of the first condenser plate 2 and the second condenser plate 3 is similar to the downward flapping of wings by a butterfly.

[0081] In one embodiment of the present invention, the opening and closing angle range of the first condensing plate 2 and the second condensing plate 3 is 5° to 40°.

[0082] like Figures 4 to 6As shown, in one embodiment of the present invention, the first condenser plate 2 and the second condenser plate 3 are rotatably disposed at the bottom of the body 1, and the first condenser plate 2 is located to the left of the second condenser plate 3. Taking the first condenser plate 2 and the second condenser plate 3 as rectangular plates, the first end of the first condenser plate 2 can be its right end and the second end can be its left end. The right end of the first condenser plate 2 is rotatably connected to the body 1, and its left end can rotate around its right end. When the first condenser plate 2 is flipped downward, the left end of the first condenser plate 2 gradually moves away from the first air inlet 12, thereby opening the first air inlet 12; when the first condenser plate 2 is flipped upward, the left end of the first condenser plate 2 gradually approaches the first air inlet 12, and when the first condenser plate 2 is in the closed position, the first condenser plate 2 covers the first air inlet 12, thereby closing the first air inlet 12.

[0083] The first end of the second condenser plate 3 can be its left end and the second end can be its right end. The left end of the second condenser plate 3 is rotatably connected to the body 1 and its right end can rotate around its left end. When the second condenser plate 3 is flipped downward, the right end of the second condenser plate 3 gradually moves away from the second air inlet 13, thereby opening the second air inlet 13. When the second condenser plate 3 is flipped upward, the right end of the second condenser plate 3 gradually approaches the second air inlet 13. When the second condenser plate 3 is in the closed position, the second condenser plate 3 covers the second air inlet 13, thereby closing the second air inlet 13.

[0084] According to an embodiment of the present invention, it can be understood that the third air inlet 14 is a normally open structure. Since the normally open third air inlet 14 is combined with the first air inlet 12 and the second air inlet 13, which can be controlled by a switch, in the range hood, the range hood according to the embodiment of the present invention will have more speed settings and functions, so that the user can choose to open or close the first air inlet 12 and / or the second air inlet 13 according to the actual usage situation, thereby switching the range hood to different speed settings to achieve different functions.

[0085] In one embodiment of the present invention, the user can close the first air inlet 12 and the second air inlet 13, so that the range hood can only draw in oil fumes through the third air inlet 14. At this time, the range hood is set to either the light smoke setting or the exhaust setting. The specific setting can be adjusted by adjusting the power of the fan inside the range hood. This is suitable for situations with no oil fumes or very little oil fumes, such as steaming food or purifying indoor air.

[0086] In another embodiment of the present invention, the user can open one of the first air inlet 12 and the second air inlet 13, so that two of the first air inlet 12, the second air inlet 13 and the third air inlet 14 are in the open state.

[0087] In one embodiment of the present invention, the user can simultaneously open the first air inlet 12 and the second air inlet 13, so that all three air inlets of the range hood are in the open state. At this time, the range hood is in the low, high or stir-fry mode. The specific mode can be adjusted by adjusting the power of the fan inside the range hood, which is suitable for situations with a lot of oil fumes, such as stir-frying.

[0088] Multiple selection buttons can be set on the body 1 to correspond to multiple speed settings of the range hood. For example, the first button, the second button, the third button, the fourth button and the fifth button on the body 1 correspond to the light smoke setting, the exhaust setting, the low setting, the high setting and the stir-fry setting, respectively.

[0089] In related technologies, the condenser plate (unless otherwise specified, the condenser plate refers to at least one of the first condenser plate 2 and the second condenser plate 3) is usually embedded in the air inlet. Therefore, even when the condenser plate closes the air inlet, there will be a gap between the condenser plate and the body, which may cause oil droplets formed by the condensation of oil fumes to drip through the gap, thus affecting the user experience and making cleaning inconvenient.

[0090] like Figures 4 to 8 As shown, to solve the above-mentioned technical problems, according to an embodiment of the present invention, a mounting platform 15 is formed at the bottom of the body 1. A first air inlet 12, a second air inlet 13, and a third air inlet 14 are formed on the mounting platform 15. In the closed position of the first condensing plate 2, at least the open side of the first condensing plate 2 overlaps with the mounting platform 15, and / or, in the closed position of the second condensing plate 3, at least the open side of the second condensing plate 3 overlaps with the mounting platform 15. Thus, since the first condensing plate 2 overlaps with the mounting platform 15 in the closed position, and / or the second condensing plate 3 overlaps with the mounting platform 15, there is no gap between the first condensing plate 2 and / or the second condensing plate 3 and the mounting platform 15 as in related technologies. Therefore, dripping of condensed oil can be prevented, improving the user experience, and making the range hood more aesthetically pleasing and easier to clean.

[0091] According to an embodiment of the present invention, the phrase "at least the open side of the first condenser plate 2 overlaps with the mounting platform 15" refers to at least the second end of the first condenser plate 2 overlapping with the mounting platform 15. For example, in the closed position, the first condenser plate 2 may have only its second end overlapping the mounting platform 15, or other ends may overlap the mounting platform 15. Of course, the present invention does not impose any special limitations here, as long as at least the open side of the first condenser plate 2 overlaps with the mounting platform 15. The structure of the second condenser plate 3 is similar to that of the first condenser plate 2, and will not be described again here.

[0092] like Figures 1 to 6As shown, according to an embodiment of the present invention, the first air inlet 12, the second air inlet 13, and the third air inlet 14 are arranged in a triangular pattern and spaced apart. This arrangement of the three air inlets is more rational and can better absorb fumes from different locations, thereby further improving the fume extraction effect of the range hood. For example, the third air inlet 14 is located on the front side of the body 1, the first air inlet 12 is located on the left side of the body 1, and the second air inlet 13 is located on the right side of the body 1. Of course, the embodiments of the present invention are not limited to this; as long as the three air inlets are arranged in a triangular pattern and spaced apart, it is acceptable.

[0093] like Figure 3 As shown, according to one embodiment of the present invention, the first air inlet 12 and the second air inlet 13 are symmetrically arranged. In this way, on the one hand, the first condenser plate 2 and the second condenser plate 3 can be designed with the same structure and size, thereby facilitating the manufacturing and assembly of the first condenser plate 2 and the second condenser plate 3; on the other hand, the symmetrical arrangement of the air inlets can better adapt to the situation of home use and improve the user experience.

[0094] like Figure 5 As shown, in one embodiment of the present invention, the first air inlet 12, the second air inlet 13, and the third air inlet 14 are arranged in an isosceles triangle, wherein the third air inlet 14 corresponds to the vertex of the isosceles triangle. This further improves the smoke extraction effect of the range hood.

[0095] like Figures 3 to 6 As shown, according to one embodiment of the present invention, the mounting platform 15 includes a first sidewall with a first air inlet 12, a second sidewall with a second air inlet 13, a third sidewall with a third air inlet 14, and a bottom surface connecting the first, second, and third sidewalls. The first, second, and third sidewalls all gradually slope downwards towards the bottom surface. In this way, the mounting platform 15 can form a downwardly convex structure. This downwardly convex structure of the mounting platform 15 can increase the contact area between the first air inlet 12, the second air inlet 13, and the third air inlet 14 and the air, thereby further improving the fume extraction performance of the range hood.

[0096] like Figures 3 to 6 As shown, in one embodiment of the present invention, the first sidewall of the mounting platform 15 is its left sidewall, which extends to the right and downward; the second sidewall is its right sidewall, which extends to the left and downward; and the third sidewall is its front sidewall, which extends to the rear and downward.

[0097] like Figure 6As shown, according to one embodiment of the present invention, the first end of the first condenser plate 2 is rotatably connected to the bottom surface of the mounting platform 15, and / or, the first end of the second condenser plate 3 is rotatably connected to the bottom surface of the mounting platform 15. This makes the assembly of the first condenser plate 2 and the second condenser plate 3 more convenient, and in the open position, the ventilation area of ​​the ventilation zone opened by the first condenser plate 2 and / or the second condenser plate 3 is larger, facilitating more efficient intake of fumes by the range hood. For example, the right end of the first condenser plate 2 is hinged to the bottom surface of the mounting platform 15, and the left end of the second condenser plate 3 is hinged to the bottom surface of the mounting platform 15. Of course, the present invention does not impose special limitations on the connection structure of the first condenser plate 2 and the second condenser plate 3 to the bottom surface of the mounting platform 15, as long as their respective first ends are rotatably connected to the bottom surface of the mounting platform 15.

[0098] According to one embodiment of the present invention, at least one of the first sidewall, the second sidewall, the third sidewall, and the bottom surface is inclined downwards and backwards. In this way, at least one of the first sidewall, the second sidewall, the third sidewall, and the bottom surface can guide the oil droplets formed by the condensation of oil fumes, directing the oil droplets to the rear side of the body 1, preventing the oil droplets from dripping directly onto the stove located directly below the body 1, thereby improving the user experience.

[0099] like Figure 10 As shown, in one embodiment of the present invention, the first sidewall, the second sidewall, the third sidewall and the bottom surface are all inclined downwards and backwards, which can further improve the guiding effect of the range hood on the condensed oil and make the guiding effect better.

[0100] like Figure 4 As shown, according to one embodiment of the present invention, the range hood further includes an oil cup 4, adapted to store condensed oil, disposed at the bottom of the body 1 and located below the rear side of the mounting platform 15. In this way, condensed oil guided by the first sidewall, second sidewall, third sidewall, and / or bottom surface can flow into the oil cup 4 and be collected, thereby preventing oil droplets from dripping from the range hood, improving the user experience, and providing an aesthetically pleasing and easy-to-clean structure. For example, the oil cup 4 can be a semi-cylindrical groove with the opening facing upwards, extending along the length of the body 1. Of course, the present invention is not limited to this, as long as the oil cup 4 can store condensed oil.

[0101] like Figure 1As shown, according to one embodiment of the present invention, the range hood further includes: a first air mesh 5, a second air mesh 6, and a third air mesh 7. The first air mesh 5, the second air mesh 6, and the third air mesh 7 are respectively embedded within the first air inlet 12, the second air inlet 13, and the third air inlet 14. The first air mesh 5 is located above the first condenser plate 2, and the second air mesh 6 is located above the second condenser plate 3. Thus, the first air mesh 5, the second air mesh 6, and the third air mesh 7 can filter oil fumes and also guide condensed oil. For example, the tilt direction of the first air mesh 5 is similar to the tilt direction of the first sidewall, the tilt direction of the second air mesh 6 is similar to the tilt direction of the second sidewall, and the tilt direction of the third air mesh 7 is similar to the tilt direction of the third sidewall. Of course, the installation direction of the first air mesh 5, the second air mesh 6, and the third air mesh 7 is not limited to this.

[0102] In some embodiments of the present invention, the first air mesh 5, the second air mesh 6, and the third air mesh 7 can be elongated mesh, honeycomb mesh, or rectangular mesh, etc. The present invention does not make any special limitation, as long as the first air mesh 5, the second air mesh 6, and the third air mesh 7 are mesh-like.

[0103] like Figure 1 As shown, according to one embodiment of the present invention, the range hood further includes an opening and closing device 8.

[0104] The opening and closing device 8 is connected to the first condensing plate 2 and the second condensing plate 3 respectively, and is suitable for controlling the rotation of the first condensing plate 2 and the second condensing plate 3 separately or synchronously. In this way, by controlling the rotation of the first condensing plate 2 and the second condensing plate 3 through the opening and closing device 8, the automatic opening or closing of the first air inlet 12 and the second air inlet 13 is realized, and the structure is stable.

[0105] In some embodiments of the present invention, the opening and closing device 8 includes a driving component, which may be a cylinder, a hydraulic cylinder, or a drive motor, etc. There may be one or more driving components. The opening and closing device 8 also includes a transmission component, which may be a gear transmission mechanism, a belt transmission mechanism, or a chain transmission mechanism, etc. The present invention does not specifically limit the driving method and transmission structure of the opening and closing device 8, as long as the opening and closing device 8 can control the rotation of the first condensing plate 2 and the second condensing plate 3.

[0106] like Figures 12 to 14As shown, in one embodiment of the present invention, the opening and closing device 8 includes a swingable first connecting arm 81 located on the left and a swingable second connecting arm 82 located on the right. A first connecting hole is provided on the first air mesh 5 for the first connecting arm 81 to pass through, and a second connecting hole is provided on the second air mesh 6 for the second connecting arm 82 to pass through. The length of the first connecting hole is greater than the width of the first connecting arm 81, and the length of the second connecting hole is greater than the width of the second connecting arm 82, to facilitate the swinging of the first connecting arm 81 and the second connecting arm 82. The lower end of the first connecting arm 81 is connected to the upper surface of the first condensing plate 2 and is adapted to drive the first condensing plate 2 to rotate. The lower end of the second connecting arm 82 is connected to the upper surface of the second condensing plate 3 and is adapted to drive the second condensing plate 3 to rotate. This provides sufficient installation space for the opening and closing device 8 and prevents the first air mesh 5 and the second air mesh 6 from interfering with the opening and closing action of the opening and closing device 8.

[0107] like Figure 1 As shown, according to one embodiment of the present invention, the range hood further includes: a first inner lining plate 9 and a second inner lining plate 10.

[0108] The first inner lining plate 9 is fixed to the side of the first condensing plate 2 adjacent to the first air inlet 12, and the second inner lining plate 10 is fixed to the side of the second condensing plate 3 adjacent to the second air inlet 13. In this way, the first inner lining plate 9 and the second inner lining plate 10 can respectively strengthen the structural strength of the first condensing plate 2 and the second condensing plate 3, making the overall structure of the range hood more stable. For example, the first inner lining plate 9 is fixed to the upper surface of the first condensing plate 2, and the second inner lining plate 10 is fixed to the upper surface of the second condensing plate 3.

[0109] The structure of a range hood according to a specific embodiment of the present invention is described below with reference to the accompanying drawings.

[0110] like Figures 1 to 14 As shown, the range hood includes a body 1, a first condensing plate 2, a second condensing plate 3, an oil cup 4, and an opening / closing device 8. The bottom of the body 1 has a first air inlet 12, a second air inlet 13, and a third air inlet 14. The third air inlet 14 is triangular and formed on the front side wall of the mounting platform 15, with each side ranging from 80mm to 450mm. The first air inlet 12 is formed on the left side wall of the mounting platform 15, and the second air inlet 13 is formed on the right side wall of the mounting platform 15. The first air inlet 12 and the second air inlet 13 are rectangular openings and symmetrically arranged, with each side ranging from 100mm to 450mm.

[0111] The first air mesh 5, the second air mesh 6, and the third air mesh 7 are respectively embedded within the first air inlet 12, the second air inlet 13, and the third air inlet 14, and are all honeycomb meshes. The first condenser plate 2 is located below the first air mesh 5, with its right end hinged to the bottom surface of the mounting platform 15. The second condenser plate 3 is located below the second air mesh 6, with its left end hinged to the bottom surface of the mounting platform 15. In the closed position, the edges of the first condenser plate 2 and the second condenser plate 3 overlap the bottom surface of the body 1 from the outside. That is, the length and width of the first condenser plate 2 are both greater than the length and width of the first air inlet 12, and the length and width of the second condenser plate 3 are both greater than the length and width of the second air inlet 13. The above-mentioned overlapping structure can avoid the gap between the condenser plate and the air inlet that occurs during embedded installation, which improves the oil guiding performance and overall aesthetics of the machine.

[0112] The range hood according to the embodiments of the present invention can be adapted to the working conditions of more users' homes, and can provide more speed settings and functions; in addition, the multi-duct design can optimize and improve the range hood's ability to extract oil fumes; furthermore, the range hood looks cleaner and tidier than traditional range hoods when it is turned off.

[0113] The structure of a range hood according to another specific embodiment of the present invention is described below with reference to the accompanying drawings.

[0114] like Figure 15 As shown, the range hood does not have a first condenser plate and a second condenser plate. That is to say, the first air inlet, the second air inlet and the third air inlet are in a normally open state. The other structures are similar to the range hood in the above embodiment, and will not be repeated here.

[0115] The above embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Although the invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the invention do not depart from the spirit and scope of the invention and should be covered within the scope of the claims of the invention.
