DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of the utility model.

[0030] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the utility model.

[0031] See also Figures 1 to 9 The embodiment of the present invention proposes a range hood 10, which includes a casing 100, a fan 200 and an oil guide 300. The casing 100 includes a box body 110, a smoke hood 120, an oil net 130 and an oil cup 140. The smoke hood 120 is arranged at the bottom of the box body 110, and the oil cup 140 is arranged at the bottom of the smoke hood 120. The smoke hood 120 is provided with a smoke inlet, and the oil net 130 is located at the smoke inlet; the fan 200 is arranged obliquely in the box body 110, and is opposite to the oil net 130 and is arranged at intervals; the oil guide 300 is located between one end of the fan 200 close to the oil net 130 and the oil net 130, and the oil guide 300 is used to guide the oil of the fan 200 to the oil cup 140. In this way, since the fan 200 is set at an angle instead of the traditional vertical installation method, the oil guide member 300 can be located between the position of the fan 200 closest to the oil net 130 and the oil net 130, so that the volume of the oil guide member 300 does not need to be designed to be larger, so that the smaller oil guide member 300 can guide the oil of the fan 200 to the oil cup 140, thereby helping to reduce the risk of the oil guide member 300 affecting the oil fume suction of the fan 200.

[0032] As will be appreciated, the oil guide 300 is located directly below the fan 200 and between the oil screen 130. When the fan 200 is mounted vertically, a large oil receiving area is required at the bottom of the fan 200, resulting in a larger design for the oil guide 300. When the fan 200 is mounted at an angle, the oil receiving area at the bottom of the fan 200 decreases from a large area to a small area, allowing the oil guide 300 to be designed to be smaller accordingly.

[0033] In some embodiments, the volute 210 of the fan 200 may be provided with a through hole, and the through hole of the volute 210 of the fan 200 may be located above the oil guide member 300 so that the fan 200 guides the oil to the oil cup 140 through the through hole.

[0034] See also Figure 3 The projection of the fan 200 from the housing 110 toward the fume hood 120 covers the oil screen 130. This means that the vertical projection of the fan 200 is greater than or equal to the area of ​​the oil screen 130. This design ensures that oil droplets accumulated on the top of the housing 110 will not directly pass through the pores of the oil screen 130 and drip onto the stove below, reducing the risk of oil droplets directly dripping onto the stove.

[0035] Furthermore, the cover design of the fan 200 allows oil droplets to be first captured by the fan 200 and then guided to the oil cup 140 by the oil guide 300. This not only ensures that the oil droplets are effectively collected, but also prevents the oil droplets from being randomly scattered within the housing 110, making the oil path more clearly defined and easier to manage and clean.

[0036] Furthermore, by ensuring that the fan 200 can intercept the oil droplets from the top of the housing 110, the possibility of the oil droplets falling onto the heat source (stove) can be reduced, thereby reducing safety hazards such as fire.

[0037] See also Figure 2 and Figure 9 In some embodiments, the housing 110 includes a back plate 112 and a front plate 111 spaced apart. The oil screen 130 is tilted downward from the front plate 111 toward the back plate 112. The oil screen 130 is provided with oil guide holes 131, which direct the oil from the oil screen 130 to the oil cup 140. This tilted arrangement of the oil screen 130 allows gravity to naturally drain any oil droplets caught by the oil screen 130. The design of the oil guide holes 131 allows the oil droplets to flow along the inclined surface to the lower end of the oil screen 130, where they then flow through the oil guide holes 131 into the oil cup 140, without the need for additional power.

[0038] In addition, the inclined design of the oil net 130 facilitates the rapid sliding of oil droplets, reducing the time that oil droplets stay on the oil net 130 , thereby reducing the chance of oil accumulation on the oil net 130 and keeping the oil net 130 clean.

[0039] Moreover, since the oil droplets can flow into the oil cup 140 quickly through the oil guide hole 131, thick oil stains are not easily formed on the surface of the oil screen 130, which greatly reduces the workload of the user when cleaning the oil screen 130 and makes maintenance easier.

[0040] In some embodiments, the angle between the oil screen 130 and the plane of the cross section of the housing 110 is between 15 and 20 degrees. The angle between the oil screen 130 and the plane of the cross section of the housing 110 can be, but is not limited to, 15, 16, 17, 18, 19, or 20 degrees. By setting the angle between the oil screen 130 and the plane of the cross section of the housing 110 to 15 to 20 degrees, it ensures that oil droplets captured by the oil screen 130 flow smoothly along the surface of the oil screen 130 under the influence of gravity. This angle range is neither too steep nor too flat, effectively leveraging gravity to help the oil droplets converge toward the lower end of the oil screen 130, where they then flow through the oil guide holes 131 into the oil cup 140.

[0041] In addition, a reasonable tilt angle helps to reduce the time that oil droplets stay on the surface of the oil net 130, reducing the possibility of oil stains solidifying on the oil net 130, making the oil net 130 easier to clean, while also reducing the accumulation of oil stains on the surface of the oil net 130 and improving cleaning efficiency.

[0042] See also Figure 4 In some embodiments, the end of the front panel 111 closest to the fume hood 120 is located above the oil screen 130, facing and spaced apart from it. This prevents condensed oil droplets from forming on the inner wall of the housing 110, particularly on the front panel 111, when the range hood 10 is in operation. The design of the front panel 111 being located above the oil screen 130 and maintaining a certain distance from it allows these oil droplets to naturally slide onto the oil screen 130 under the action of gravity. This design ensures that oil droplets do not drip directly onto the stovetop or other locations, but are first captured by the oil screen 130.

[0043] Furthermore, the relative positioning of the front plate 111 and the oil screen 130 allows oil droplets to flow smoothly from the front plate 111 to the oil screen 130, and then to the oil cup 140 through the oil guide holes 131 in the oil screen 130. This ensures that the oil droplets flow along the intended path, preventing oil droplets from splashing around inside the housing 110 and reducing the accumulation of oil stains inside.

[0044] See also Figure 5 In some embodiments, the housing 110 further includes a deflector 117. One end of the deflector 117 is connected to the end of the back panel 112 near the fume hood 120, while the other end of the deflector 117 is located above, opposite, and spaced from the oil screen 130. This design ensures that oil droplets condensed or accumulated on the back panel 112 are effectively collected along the deflector 117. The back panel 112 is typically one of the areas within the range hood where oil droplets easily accumulate. The presence of the deflector 117 prevents these oil droplets from dripping freely, but instead allows them to flow along a predetermined path.

[0045] In addition, due to the presence of the guide plate 117, the oil droplets are concentrated on the oil net 130, reducing the random distribution of oil droplets in the box body 110, making the interior of the box body 110 cleaner, and also reducing the workload of cleaning other parts outside the oil net 130.

[0046] See also Figure 6 and Figure 7In some embodiments, the housing 110 further includes a first side panel 113 and a second side panel 114 spaced apart from each other. The first side panel 113 is connected between the front panel 111 and the back panel 112, and the second side panel 114 is connected between the front panel 111 and the back panel 112. The end of the first side panel 113 closer to the fume hood 120 is located above the oil screen 130, and the end of the second side panel 114 closer to the fume hood 120 is located above the oil screen 130. In this way, the ends of the first and second side panels 113, 114 closer to the fume hood 120 are located above the oil screen 130, which means that oil droplets on the side panels can naturally slide onto the oil screen 130 under the action of gravity. This design ensures that oil droplets on the side panels do not drip into other places within the housing 110, but are instead captured by the oil screen 130 and flow into the oil cup 140 through the oil guide hole 131.

[0047] See also Figures 6 to 8 In some embodiments, the oil guide member 300 includes a first oil guide plate 310, a second oil guide plate 320, and a third oil guide plate 330. The second oil guide plate 320 is connected between the first and third oil guide plates 310, 330. The first and third oil guide plates 310, 330 are spaced apart from each other. The first, second, and third oil guide plates 310, 320, 330 together form an oil guide groove 340. The width of the oil guide groove 340 gradually decreases from the fan 200 toward the oil cup 140. This gradually decreasing width of the oil guide groove 340 from the fan 200 toward the oil cup 140 helps form a streamlined passage. This design reduces turbulence when air passes through the oil guide groove 340, ensuring smoother airflow and improving air intake efficiency at the air inlet.

[0048] In addition, as the width of the oil guide groove 340 gradually narrows, the resistance encountered by the air flow is also reduced accordingly. This means that the fan 200 can more easily promote air flow during operation, reducing energy loss and improving the energy efficiency of the range hood 10.

[0049] Furthermore, by reducing turbulence, vibrations caused by poor air flow can be reduced. Reduced vibration means lower noise levels, providing a quieter operating environment and improving the user experience.

[0050] See also Figure 6 and Figure 8 In some embodiments, housing 110 includes a housing body 115 and a back panel 112. Housing body 115 and back panel 112 together enclose a fan accommodation space 116. Fan 200 is located in fan accommodation space 116. Back panel 112 is detachably connected to housing body 115, for example, by threaded or snap-fit ​​connection. The air inlet of fan 200 faces back panel 112.

[0051] Thus, the back panel 112 is detachably connected to the housing body 115, allowing the user to easily remove the back panel 112 for cleaning or replacement. This allows for easier access to the fan 200 and the interior of the fan accommodating space 116, facilitating the cleaning of accumulated oil stains and dust, and improving the maintenance convenience of the device.

[0052] Furthermore, the removable back panel 112 design makes it easier for the user to clean or inspect the fan 200, reducing safety hazards caused by the inability to directly access the fan 200. Furthermore, the back panel 112 design can act as a layer of protection, preventing foreign matter from directly entering the fan 200 and protecting the fan 200 from damage.

[0053] Moreover, by providing a back panel 112 that is easy to disassemble and install, users can perform daily maintenance work more easily, reducing the complexity and time cost of maintenance, thereby improving the user experience of the product.

[0054] In some embodiments, the fan 200 includes a volute 210, a motor 220, a locking nut 230, an air guide ring 240, and an impeller 250. The housing of the motor 220 is detachably connected to the volute 210, for example, the housing of the motor 220 is screwed or snap-connected to the volute 210, and the drive shaft of the motor 220 passes through the impeller 250 and locks the impeller 250 through the locking nut 230. The air guide ring 240 is located at the air inlet of the fan 200 and is detachably connected to the volute 210, for example, the air guide ring 240 is screwed or snap-connected to the volute 210.

[0055] Thus, because the motor 220 housing 100 is detachably connected to the volute 210, and the air guide ring 240 is also detachably connected to the volute 210, this design allows key components of the fan 200 to be easily removed for inspection, cleaning, or replacement. This not only simplifies maintenance work but also reduces maintenance difficulties caused by fixed installation.

[0056] In addition, an air guide ring 240 is located at the air inlet of the fan 200 and is detachably connected to the volute 210. The air guide ring 240 helps guide the airflow entering the fan 200, making it more uniform and stable, thereby improving the suction efficiency of the fan 200. The detachable design also facilitates regular cleaning of the air guide ring 240 to maintain its optimal performance.

[0057] Furthermore, the impeller 250 is locked to the drive shaft of the motor 220 by the locking nut 230, which ensures the stability of the impeller 250 during high-speed rotation and reduces malfunctions caused by looseness or displacement. Furthermore, the detachable design facilitates the timely replacement of worn impellers 250 or repair of problems.
