Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a range hood. Background Art

[0002] A range hood is typically installed above a kitchen stove. Its primary function is to quickly extract and exhaust harmful cooking fumes from stovetop combustion and the cooking process. It also collects the condensed oil from the fumes. The range hood consists of three main steps: fume extraction, fume separation, and residual gas exhaust. When the range hood is powered on, the motor rotates at high speed, driving the impeller at the same time. This creates a vortex of negative pressure, drawing the fumes into the hood. After passing through the filter and centrifugal force, the fumes are separated and discharged through a check valve and exhaust pipe.

[0003] However, when a user uses an existing range hood, negative pressure is generated at the air intake, causing oil smoke to enter the interior of the range hood. Simultaneously, when the motor rotates at high speed, the oil drip hole connects to the interior of the range hood, creating negative pressure there as well. This allows oil smoke and outside wind to easily enter the oil drip hole, blocking the downward flow of oil and preventing it from dripping smoothly into the oil cup for collection.

[0037] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0038] See also Figures 1 to 5 The utility model provides a range hood, comprising a range hood body 1, an air-blocking and oil-leakage component 2 and an oil cup 3.

[0039] The range hood body 1 includes a front panel 11 and a back panel 12, with a cavity defined between them. The front panel 11 is provided with an air intake 13, which communicates with the cavity. When the range hood is in use, negative pressure is generated at the air intake 13 on the front panel 11, allowing cooking fumes to enter the range hood body 1 through the air intake 13 on the front panel 11. The cooking fumes inside the range hood body 1 are then exhausted to the outside.

[0040] The air choke and oil leakage assembly 2 includes an oil drip plate 21 and an oil guide plate 22. Both ends of the oil drip plate 21 and the oil guide plate 22 are detachably connected to the front panel 11 and the back panel 12, respectively. The oil drip plate 21 is mounted at the bottom of the cavity and defines an oil drip hole 211 communicating with the cavity. The oil guide plate 22 is tilted within the cavity and defines an oil guide hole 221. The oil guide hole 221 is located at the lower end of the oil guide plate 22, and the projection of the oil guide hole 221 deviates from the projection of the oil drip hole 211. In this embodiment, the oil guide plate 22 is tilted within the cavity, from high to low, in the direction from the back panel 12 to the front panel 11. The oil condensed from cooking fumes within the range hood body 1 flows from the cavity onto the oil guide plate 22. The oil on the oil guide plate 22 flows through the oil guide holes 221 onto the oil drip plate 21, thereby guiding the oil. The oil on the oil drip plate 21 then flows through the oil drip holes 211 into the oil cup 3 for collection. Furthermore, when cooking fumes or outside wind enter the oil drip holes 211, the inclined bottom of the oil guide plate 22 reduces the direct impact of the fumes or outside wind on the oil, thereby blocking the fumes or outside wind and enabling smoother oil collection.

[0041] The oil cup 3 is detachably mounted on the bottom of the oil drip plate 21. Specifically, the oil cup 3 is detachably mounted on the bottom of the oil drip plate 21 via an oil cup 3 fixing member; in this embodiment, the oil cup 3 fixing member is a snap, which secures the oil cup 3 to the bottom of the oil drip plate 21.

[0042] When a user uses the range hood, negative pressure is generated at the air intake 13 on the front panel 11, allowing oil smoke to enter the interior of the range hood body 1 through the air intake 13 on the front panel 11. The oil smoke inside the range hood body 1 is then discharged to the outside. At the same time, oil condensed from the oil smoke inside the range hood body 1 flows from the cavity onto the oil guide plate 22. The oil on the oil guide plate 22 flows through the oil guide holes 221 to the oil drip plate 21, thereby guiding the oil. The oil on the oil drip plate 21 then flows through the oil drip hole 211 into the oil cup 3 for collection. Furthermore, when oil smoke or external wind enters the oil drip hole 211, the inclined bottom of the oil guide plate 22 reduces the oil smoke or external wind from directly blowing towards the oil, thereby blocking the oil smoke or external wind and enabling more smooth oil collection.

[0043] Based on the above examples, please refer to Figure 3 and Figure 4 The oil guide plate 22 of the present invention has an inclined portion 222 and a parallel portion 223 .

[0044] The top end of the inclined portion 222 is detachably connected to the back panel 12, and the two ends of the parallel portion 223 are respectively connected to the lower end of the inclined portion 222 and the front panel 11. The oil guide hole 221 is provided at the connection between the inclined portion 222 and the parallel portion 223. In this embodiment, the top end of the inclined portion 222 is detachably connected to the back panel 12 via screws; the oil guide hole 221 can be a flat hole. The right end of the parallel portion 223 is integrally connected to the lower end of the inclined portion 222; the right end of the parallel portion 223 can also be detachably connected to the lower end of the inclined portion 222 via screws. The left end of the inclined portion 222 is detachably connected to the front panel 11 via screws. When the range hood is in use, oil drops onto the inclined portion 222, which guides the oil so that it flows to the parallel portion 223, and then flows out from the oil guide hole 221. At the same time, the inclined portion 222 blocks the oil smoke or external wind, reducing the oil smoke or external wind from blowing directly onto the oil.

[0045] Based on the above examples, please refer to Figure 3 and Figure 5 The air-blocking and oil-leakage prevention assembly 2 of the present invention also includes an oil collection box 23. The oil collection box 23 is located in the cavity at the top of the oil guide plate 22. The two ends of the oil collection box 23 are removably connected to the back plate 12 and the air collection assembly of the range hood body 1. In this embodiment, the oil collection box 23 is installed in the cavity, located above the oil guide plate 22 and the air intake 13. The two ends of the oil collection box 23 are removably connected to the back plate 12 and the air collection assembly of the range hood body 1 via screws.

[0046] The oil collection box 23 has an oil collection groove, which is arranged at an angle, with its top end positioned below the oil drip hole 211 of the air collection assembly in the range hood body 1. Specifically, the oil collection groove is arranged from high to low in the direction from the front panel 11 to the back panel 12, and its bottom end is connected to the back panel 12. By installing the oil collection box 23 above the oil guide plate 22 and the air intake 13, when the range hood is in use, oil smoke enters the cavity through the air intake 13, then enters the air collection assembly of the range hood body 1 and is discharged to the outside. At the same time, the oil dripping from the air collecting assembly of the range hood body 1 falls into the oil receiving groove in the oil receiving box 23. The oil receiving box 23 blocks the upward oil smoke to prevent the oil smoke from blowing directly onto the oil; and the oil receiving groove guides the oil so that the oil can flow smoothly in the oil receiving box 23; the oil in the oil receiving groove then flows to the back plate 12, so that the oil can quickly flow down along the back plate 12, and then the oil flows into the oil cup 3 for collection, thereby preventing the oil smoke flowing upward in the cavity from affecting the oil.

[0047] Based on the above examples, please refer to Figure 3 and Figure 5The oil receiving box 23 of the present invention includes an oil receiving plate 231 and an oil receiving side plate 232 .

[0048] The two ends of the oil receiving plate 231 are detachably connected to the back panel 12 and the air collecting assembly of the range hood body 1, respectively. The two oil receiving side panels 232 are provided with two pieces. The bottom ends of the two oil receiving side panels 232 are respectively mounted on the oil receiving plate 231. The side surfaces of the oil receiving side panels 232 are trapezoidal or triangular. The oil receiving plate 231 and the two oil receiving side panels 232 form the oil receiving groove. In this embodiment, the two ends of the oil receiving plate 231 are detachably connected to the back panel 12 and the air collecting assembly of the range hood body 1 by screws, and the bottom ends of the two oil receiving side panels 232 are respectively mounted on the oil receiving plate 231 by bonding or welding, so that the oil receiving plate 231 and the two oil receiving side panels 232 form an oil receiving groove. The oil receiving side panels 232 limit the oil, and the oil flows in the oil receiving groove so that the oil can be better guided through the oil receiving groove.

[0049] Based on the above examples, please refer to Figure 3 and Figure 4 The present invention provides multiple oil guide holes 221, with the number of oil guide holes 221 near the center of the oil guide plate 22 being greater than the number near the edges of the oil guide plate 22. In this embodiment, there are eleven oil guide holes 221; five of these are near the center of the oil guide plate 22, and three are located on the left and right sides of the oil guide plate 22. When oil drips onto the oil guide plate 22, it concentrates in the center. By providing more oil guide holes 221 in the center of the oil guide plate 22, the oil can flow out more quickly from the multiple oil guide holes 221, allowing the oil to drip onto the oil drip plate 21 more quickly.

[0050] Based on the above examples, please refer to Figure 1 and Figure 2 The oil drip plate 21 of the present invention has a convex groove 212 facing the oil cup 3. The convex groove 212 is provided with a plurality of oil drip holes 211. Specifically, the convex groove 212 is provided with six oil drip holes 211. Due to the provision of the convex groove 212, when the range hood is in use, oil smoke enters the convex groove 212 from the oil drip holes 211. The groove wall of the convex groove 212 guides the oil smoke, allowing it to flow better along the notch direction of the convex groove 212. At the same time, the oil flowing down the back plate 12 and the oil dripping from the oil guide hole 221 flow onto the oil drip plate 21. The oil on the oil drip plate 21 flows into the convex groove 212, and the oil in the convex groove 212 flows into the oil cup 3 through the oil drip holes 211 for collection.

[0051] Based on the above examples, please refer to Figure 3 and Figure 4 The convex groove 212 of the present invention is disposed in the middle of the oil drip plate 21. This placement of the convex groove 212 facilitates the flow of oil from the oil drip plate 21 into the convex groove 212. Furthermore, the convex groove 212 guides the oil smoke that enters the oil drip hole 211, allowing it to blow directly to the bottom of the oil guide plate 22, thus preventing the oil smoke from obstructing the oil.

[0052] Based on the above examples, please refer to Figure 1 、 Figure 3 and Figure 4 The oil cup 3 of the present invention has a side portion 331 extending toward the front panel 11. The front panel 11 is tilted, slanting from top to bottom toward the back panel 12. The side portion 331 is located in front of the bottom end of the front panel 11. By providing the side portion 331 and tilting the front panel 11, oil on the front panel 11 flows downward during use of the range hood and drips into the oil cup 3, thereby collecting the oil on the front panel 11.

[0053] Based on the above examples, please refer to Figure 3 and Figure 4 The orifice area of the oil guide hole 221 of the present invention is 3-20 times smaller than the orifice area of the oil dripping hole 211. In this embodiment, the orifice area of the oil guide hole 221 is 13 times smaller than the orifice area of the oil dripping hole 211. Similarly, the orifice area of the oil guide hole 221 can also be smaller than 3 times or 20 times the orifice area of the oil dripping hole 211.

[0054] Based on the above examples, please refer to Figure 1 and Figure 2 The range hood body 1 of the present invention further includes a side panel assembly 14 .

[0055] The side panel assembly 14 is located above the oil cup 3 . Two side panel assemblies 14 are provided, and the two side panel assemblies 14 are respectively installed on the left and right sides of the range hood body 1 .

[0056] The side panel assembly 14 includes a windshield side panel, which is removably mounted to the range hood body 1 via the oil-intake side panel 232 fasteners. In this embodiment, the oil-intake side panel 232 fasteners are screws, and the windshield side panel is removably mounted to the range hood body 1 via these screws. With the side panel assembly 14, the windshield side panel blocks cooking fumes while the range hood is in use, preventing them from escaping the hood body 1. This allows the air intake 13 to absorb more cooking fumes, preventing them from entering other areas of the kitchen.

[0057] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein.
