[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] In this document, references to "embodiment" or "implementation" mean that a particular feature, structure, or characteristic described in connection with an embodiment or implementation may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0043] Range hoods are a common kitchen appliance in modern homes. They primarily work by using a high-speed rotating fan to create negative pressure, thereby drawing in and removing cooking fumes. However, current range hood designs place the air intake at the top of the hood, which results in incomplete fume extraction, leading to fume diffusion and escape, and ultimately increasing the amount of cooking fumes in the kitchen.

[0044] Therefore, this embodiment provides a range hood 100. The range hood 100 can reduce the diffusion of cooking fumes.

[0045] Please see Figure 1 and Figure 2 A range hood 100, the range hood 100 includes: a fan 20, a smoke collection hood 10, a first flow guiding component 30, and a second flow guiding component 40;

[0046] The fan 20 is installed inside the smoke hood 10. The smoke hood 10 has a smoke inlet. A first mounting part 11 and a second mounting part 12 are respectively provided on both sides of the smoke hood 10.

[0047] The first flow guiding component 30 is disposed in the first mounting part 11, and the second flow guiding component 40 is disposed in the second mounting part 12. The first flow guiding component 30 and the second flow guiding component 40 are used to drive the airflow to flow towards the smoke inlet.

[0048] The aforementioned range hood 100 has a first flow guide component 30 and a second flow guide component 40 respectively arranged on the left and right sides of the smoke collection hood 10. Both the first flow guide component 30 and the second flow guide component 40 generate high-speed airflow. In this way, the first flow guide component 30 and the second flow guide component 40 gather the oil fumes generated by the stove towards the center of the smoke collection hood 10, so that the oil fumes can be gathered near the smoke inlet, reducing the diffusion range of the smoke. Then, the oil fumes enter the range hood 100 through the smoke inlet of the smoke collection hood 10, and then exhaust the oil fumes. In this way, the oil fumes can be exhausted more quickly, thereby reducing the escape of oil fumes.

[0049] Alternatively, a small amount of airflow can be discharged through the first guide component 30 and the second guide component 40 to form a smoke screen between the first guide component 30 and the second guide component 40, causing the oil fumes to accumulate between the first guide component 30 and the second guide component 40, and then the range hood 100 can suck away the oil fumes to reduce the escape of oil fumes.

[0050] Alternatively, by drawing air through the first guide assembly 30 and the second guide assembly 40, a negative pressure is generated between the first guide assembly 30 and the second guide assembly 40, causing the oil fumes to be drawn into the fume hood 10 through the first guide assembly 30 and the second guide assembly 40, and then discharged through the fume hood 10, thereby reducing the escape of oil fumes.

[0051] Understandably, the inside of the fume hood 10 is a hollow structure, and a fan 20 is installed inside it. The fan 20 is used to create negative pressure in the fume hood 10, thereby achieving the purpose of sucking up the oil fumes. A smoke inlet is provided at the bottom of the fume hood 10, which is used to suck the oil fumes into the fume hood 10. The negative pressure space generated by the fan 20 allows the oil fumes to enter the fume hood 10 through the smoke inlet.

[0052] Understandably, a first mounting part 11 is provided on the left side of the bottom of the smoke hood 10, and a second mounting part 12 is provided on the right side of the bottom of the smoke hood 10; wherein, a first flow guiding component 30 is provided on the first mounting part 11, and a second flow guiding component 40 is provided on the second mounting part 12. In this way, the first flow guiding component 30 and the second flow guiding component 40 can drive the airflow closer to the smoke inlet, or generate negative pressure so that the oil fumes can be discharged through the range hood 100.

[0053] Please see Figure 1 In some embodiments, the first flow guiding component 30 includes: a first driving component 31 and a first flow guiding component 32;

[0054] The first driving member 31 is connected to the first flow guide 32. The first flow guide 32 is located on one side of the smoke hood 10. The first driving member 31 is used to drive the airflow or to generate negative pressure in the part of the smoke hood 10 close to the first flow guide 32.

[0055] The second flow guiding component 40 includes: a second driving component 41 and a second flow guiding component 42;

[0056] The second driving member 41 is connected to the second flow guide 42. The second flow guide 42 is located on one side of the smoke hood 10. The second driving member 41 is used to drive the airflow or to generate negative pressure in the part of the smoke hood 10 close to the first flow guide 32.

[0057] Understandably, the first flow guiding component 30 includes a first driving member 31 and a first flow guiding member 32. The first flow guiding member 32 is disposed in the first mounting part 11. The first flow guiding component 30 is used to guide airflow, and the first driving member 31 is used to generate negative pressure in the first flow guiding member 32 or to discharge high-pressure airflow from the first flow guiding member 32. The interior of the first flow guiding component 30 is a cavity, and the first driving member 31 is connected to the first flow guiding component 30. Thus, when the first driving member 31 rotates, it can generate negative pressure in the first flow guiding member 32 or generate high-pressure airflow in the first flow guiding member 32 to achieve the effect of gathering or concentrating smoke.

[0058] Understandably, the second flow guiding assembly 40 includes a second driving member 41 and a second flow guiding member 42. The second flow guiding member 42 is disposed in the second mounting part 12. The second flow guiding assembly 40 is used to guide airflow, and the second driving member 41 is used to generate negative pressure in the second flow guiding member 42 or to discharge high-pressure airflow from the second flow guiding member 42. The interior of the second flow guiding assembly 40 is a cavity, and the second driving member 41 is connected to the second flow guiding assembly 40. Thus, when the second driving member 41 rotates, it can generate negative pressure in the second flow guiding member 42 or generate high-pressure airflow in the second flow guiding member 42 to achieve the effect of gathering or concentrating smoke.

[0059] Please see Figure 1 and Figure 2 In some embodiments, the first guide member 32 has a first guide port 321, a second guide port 322, and a first guide cavity 323;

[0060] The first flow guide 321 and the second flow guide 322 are respectively disposed at both ends of the flow guide cavity; wherein, the first flow guide 321 is disposed on the side near the smoke hood 10;

[0061] The second guide member 42 includes: a third guide port 421, a fourth guide port 422, and a second guide cavity 423;

[0062] The third guide port 421 and the fourth guide port 422 are respectively disposed on both sides of the second guide cavity 423; wherein, the third guide port 421 is disposed near the side of the smoke hood 10, and the third guide port 421 is disposed opposite to the first guide port 321.

[0063] Understandably, the first guide member 32 includes a first guide port 321, a second guide port 322, and a first guide cavity 323. The first guide port 321 and the second guide port 322 are located at the two ends of the first guide cavity 323, respectively. The first guide port 321 is located near the side of the smoke hood 10, and the second guide port 322 is located near the first drive member 31. In this way, when the first drive member 31 rotates and generates a high-pressure airflow, the airflow can be discharged through the second guide port 322, the first guide cavity 323, and the first guide port 321. When the first drive member 31 rotates and generates a negative pressure, the oil fumes are allowed to enter the smoke hood 10 through the first guide port 321, the first guide cavity 323, and the second guide port 322.

[0064] Understandably, the second guide member 42 includes a third guide port 421, a fourth guide port 422, and a second guide cavity 423. The third guide port 421 and the fourth guide port 422 are located at the two ends of the second guide cavity 423, respectively. The second guide port 322 is located near the side of the smoke hood 10 and is located near the first drive member 31. In this way, when the first drive member 31 rotates and generates a high-pressure airflow, the airflow can be discharged through the second guide port 322, the first guide cavity 323, and the first guide port 321. When the first drive member 31 rotates and generates a negative pressure, the oil fumes are allowed to enter the smoke hood 10 through the first guide port 321, the first guide cavity 323, and the second guide port 322.

[0065] In some embodiments, the width of the first guide cavity 323 gradually increases from the second guide port 322 to the first guide port 321; the width of the second guide cavity 423 gradually increases from the fourth guide port 422 to the third guide port 421.

[0066] Understandably, the width of the first guide cavity 323 gradually increases from the second guide port 322 to the first guide port 321. This allows the first guide port 321 to have a larger air outlet area when air is discharged, which can reduce the airflow velocity generated by the first driving member 31 and balance the airflow velocity generated by the first driving member 31, avoiding high output airflow velocity that would affect the smoke collection effect.

[0067] Alternatively, when negative pressure is generated at the first guide port 321, the first guide port 321 has a larger smoke inlet area, which can better allow the oil fumes to enter the smoke collection hood 10 through the first smoke inlet.

[0068] Understandably, the width of the second guide cavity 423 gradually increases from the fourth guide port 422 to the third guide port 421. This allows the third guide port 421 to have a larger air outlet area when it discharges air, which reduces the airflow velocity generated by the second drive component 41 and balances the airflow velocity generated by the second drive component 41, thus avoiding high output airflow velocity that could affect the smoke collection effect.

[0069] Alternatively, when negative pressure is generated at the third inlet 421, the third inlet 421 can have a larger smoke inlet area, which can better allow the oil fumes to enter the smoke collection hood 10 through the third smoke inlet.

[0070] Please see Figure 3 In some embodiments, both the first flow guide port 321 and the third flow guide port 421 are provided with flow guide components 50.

[0071] Understandably, both the first guide port 321 and the second guide port 322 are provided with guide components 50. The guide components 50 are used to change the direction of airflow at the first guide port 321 and the third guide port 421. For example, when airflow is blown out from the first guide port 321 or the third guide port 421, the guide components 50 can change the direction of the airflow discharged from the first guide port 321 or the second guide port 322.

[0072] Please see Figure 3 In some embodiments, the flow guiding assembly 50 includes a plurality of flow guiding plates 51, a fixing frame 52, and a drive rod 53;

[0073] Multiple guide plates 51 are spaced apart within the fixing frame 52. The driving rod 53 is connected to the multiple guide plates 51 and is used to change the angle between the guide plate 51 and the horizontal direction.

[0074] Understandably, the airflow guiding assembly 50 includes a fixed frame 52 and multiple airflow guiding plates 51. The multiple airflow guiding plates 51 are spaced apart within the fixed component and are rotatably mounted on the fixed frame 52. All multiple airflow guiding plates 51 are connected to a drive rod 53. Thus, by moving the drive rod 53, the multiple airflow guiding plates 51 can be rotated, causing the angle between the multiple airflow guiding plates 51 and the horizontal plane to change. This allows the downward-flowing airflow to be guided upward through the airflow guiding plates 51 and discharged, thereby playing a role in guiding the airflow.

[0075] Optionally, the aforementioned driving component is a telescopic rod, which drives the angle between the guide plate 51 and the horizontal plane to change by extending and retracting the telescopic rod.

[0076] Please see Figure 4 In some embodiments, it also includes: a smoke collection assembly 60 and a drive assembly 70;

[0077] The smoke collection component 60 is movably disposed within the smoke collection hood 10, and the drive component 70 is fixedly disposed within the smoke collection hood 10. The drive component 70 is connected to the smoke collection component 60 and is used to drive the smoke collection component 60 to open or close.

[0078] When the smoke collection component 60 is turned on, it is located outside the smoke collection hood 10; when the smoke collection component 60 is turned off, it is located inside the smoke collection hood 10.

[0079] Understandably, the smoke collection component 60 is movably installed inside the smoke hood 10, and the drive component 70 is also installed inside the smoke hood 10. The smoke collection component 60 is connected to the drive mechanism, which can drive the smoke collection component 60 to unfold. After the smoke collection component 60 unfolds, the angle between the smoke collection component 60 and the vertical direction changes, thereby increasing the smoke absorption area and improving the smoke absorption area of ​​the range hood 100, thus reducing the escape of smoke. After the range hood 100 is used, the drive mechanism drives the smoke collection component 60 to close, and the smoke collection component 60 is located inside the smoke hood 10 to save kitchen space.

[0080] Please see Figure 4 In some embodiments, the smoke collection assembly 60 includes: a first smoke collection element 61 and a second smoke collection element 62;

That is, the first smoke collecting element 61 and the second smoke collecting element 62 are spaced apart on two opposite side walls of the smoke hood 10 (the first smoke collecting element 61 is movably mounted on the second mounting part 12). Figure 5 As shown on the left, the second smoke collection unit 62 is movably set as follows: Figure 5 As shown on the right side), the first smoke collector 61 and the second smoke collector 62 can both be driven to open or close by the drive assembly 70.

This expansion increases the smoke extraction range of the range hood 100, thereby reducing smoke escape and improving its smoke extraction efficiency. Both the first and second smoke collectors 61 and 62 are connected to the smoke hood 10; therefore, the smoke entering the first and second smoke collectors 61 and 62 enters the smoke hood 10 and is then discharged through it.

[0084] Please see Figure 4 In some embodiments, the drive assembly 70 includes a first drive mechanism 71 and a second drive mechanism 72;

[0085] The first driving mechanism 71 is disposed on the side of the smoke hood 10 near the first smoke collecting member 61, and the first driving mechanism 71 is connected to the first smoke collecting member 61.

When the first driving mechanism 71 rotates, it can drive the first smoke collecting component 61 to rotate, thereby opening the first smoke collecting component 61. When the first driving mechanism 71 rotates in the opposite direction, it can also drive the first smoke collecting component 61 to rotate, thereby closing the first smoke collecting component 61, so as to realize the opening or closing of the first smoke collecting component 61.

[0088] Understandably, the second drive mechanism 72 is located on the smoke hood 10 near the second smoke collecting component 62.
