[0019] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0020] The following is for reference. Figures 1-5 Description of a range hood 100 according to an embodiment of the present utility model.

[0021] Combination Figures 1-5 As shown, the range hood 100 of this utility model embodiment includes a range hood body, and a smoke collection chamber 10 is provided inside the range hood body. The front panel 31 is rotatably connected to the main body of the range hood to open or close the smoke collection chamber 10. Thus, the rotatable connection between the front panel 31 and the main body of the range hood allows for selective opening and closing of the smoke collection chamber 10. For example, an opening 12 can be opened on the lower side of the front panel 31, making it more convenient to clean the inner walls of the front panel 31 and the inner walls of the smoke collection chamber 10 when necessary.

[0022] Furthermore, the front panel 31 can be opened by rotating the smoke collection chamber 10, so that at least one end of the front panel 31 is connected to the main body of the range hood. This means that when cleaning the inner wall of the front panel 31 and the inner wall of the smoke collection chamber 10, the front panel 31 does not need to be removed, which further facilitates the user in cleaning the inner wall of the front panel 31 and the inner wall of the smoke collection chamber 10.

[0023] Therefore, the front panel 31 and the main body of the range hood can be rotatably connected to selectively open or close the smoke collection chamber 10, which makes it more convenient to clean the inner wall of the front panel 31 and the inner wall of the smoke collection chamber 10.

[0024] According to an optional embodiment of the present invention, such as Figures 2-5 As shown, the range hood 100 also includes a rotating assembly 40, one end of which is rotatably connected to the main body of the range hood, and the other end of which is connected to the front panel 31. In other words, the range hood 100 further includes a rotating assembly 40, wherein one end of the rotating assembly 40 is fixedly connected to the front panel 31, and the other end of the rotating assembly 40 is connected to the main body of the range hood, allowing the rotating assembly 40 to rotate around the main body of the range hood, thus enabling the front panel 31 to be rotated open, thereby opening or closing the smoke collection chamber 10, facilitating user maintenance and cleaning.

[0025] Thus, a rotating component 40 is connected between the front panel 31 and the main body of the range hood. The end of the rotating component 40 connected to the main body of the range hood can rotate, thereby allowing the front panel 31 and the rotating component 40 to rotate around the main body of the range hood, thereby opening or closing the smoke collection chamber 10.

[0026] Specifically, such as Figure 4 and Figure 5 As shown, the rotating assembly 40 includes a rotating arm 43, which comprises a first segment 431, a second segment 432, and a third segment 433 connected in sequence. The first segment 431 is rotatably connected to the main body of the range hood. One end of the second segment 432 is connected to the first segment 431, and the other end is connected to the third segment 433. The third segment 433 is connected to the front panel 31. That is, the rotating arm 43 is connected between the main body of the range hood and the front panel 31, so that the rotating arm 43 drives the front panel 31 to rotate relative to the main body of the range hood, thereby opening the smoke collection chamber 10.

[0027] Furthermore, the first segment 431 and the second segment 432 are set at an angle, and the second segment 432 and the third segment 433 are set at an angle. That is to say, the first segment 431, the second segment 432 and the third segment 433 of the rotating arm 43 are arc-shaped as a whole, which allows the rotating arm 43 to avoid the upper end of the front panel 31, thereby avoiding interference between the rotating arm 43 and the front panel 31.

[0028] Furthermore, such as Figure 5 As shown, the angle formed between the first segment 431 and the second segment 432 is smaller than the angle formed between the second segment 432 and the third segment 433. For example, the angle between the first segment 431 and the second segment 432 is a right angle, while the angle between the second segment 432 and the third segment 433 is an obtuse angle. This arrangement allows the second segment 432 to extend towards the front panel 31, avoiding interference between the second segment 432 and the rear panel of the smoke collection chamber 10. On the other hand, it allows the third segment 433 to be connected to the upper end of the front panel 31, making it convenient for the user to open the smoke collection chamber 10.

[0029] like Figure 4 As shown, the rotating assembly 40 also includes a first mounting plate 41 and a second mounting plate 42. The first mounting plate 41 is fixed to the main body of the range hood, and the second mounting plate 42 is fixed to the front panel 31. A first segment 431 is rotatably connected to the first mounting plate 41, and a third segment 433 is fixedly connected to the second mounting plate 42. In other words, the rotating assembly 40 consists of the interconnected first mounting plate 41, the second mounting plate 42, and the rotating arm 43. The first mounting plate 41 is connected to the main body of the range hood, the second mounting plate 42 is connected to the front panel 31, and the rotating arm 43 is connected between the first mounting plate 41 and the second mounting plate 42. Thus, when the rotating arm 43 rotates around the first mounting plate 41, the front panel 31 can be rotated open, thereby opening the opening 12.

[0030] Specifically, a pivot axis is provided between the rotating arm 43 and the first mounting plate 41, that is, the pivot axis passes through the first mounting plate 41 and the rotating arm 43, so that the rotating arm 43 can rotate around the pivot axis, thereby realizing the function of the rotating component 40 driving the front panel 31 to rotate and open.

[0031] The second mounting plate 42 and the rotating arm 43 are fixed together by screws. Specifically, the second mounting plate 42 has a first mounting hole and the rotating arm 43 has a second mounting hole. The screw passes through the first mounting hole and is fixedly connected to the second mounting hole, thereby fixing the second mounting plate 42 and the rotating arm 43 together.

[0032] Furthermore, the second mounting plate 42 and the front panel 31 can be fixed together by adhesive bonding.

[0033] In addition, a locking device is provided on the rotating assembly 40. When the rotating assembly 40 drives the front panel 31 to open the smoke collection chamber 10, the locking device can lock the rotating assembly 40 to keep the rotating assembly 40 and the front panel 31 in the open position. The locking device can be a hydraulic strut.

[0034] And, refer to Figure 3 and Figure 4As shown, the range hood 100 also includes a magnetic suction component 52, which is fixed to the inner side of the front panel 31. One end of the front panel 31 is rotatably connected to the main body of the range hood, and the other end is magnetically connected to the main body of the range hood. That is, the other end of the front panel 31 can be magnetically connected to the main body of the range hood via the magnetic suction component 52, so that when the front panel 31 is in its original working state, the other end of the front panel 31 and the main body of the range hood are magnetically connected via the magnetic suction component 52. Specifically, one end of the front panel 31 is rotatably connected to the main body of the range hood, and the other end of the front panel 31 is selectively attracted to the main body via the magnetic suction component 52. Thus, when it is necessary to open the smoke collection chamber, only a pulling force greater than the magnetic attraction between the magnetic suction component 52 and the main body needs to be applied to the other end of the front panel 31, and the other end of the front panel 31 will separate from the main body, allowing the front panel 31 to rotate and open the smoke collection chamber 10. The magnetic component 52 can be a powerful neodymium iron boron permanent magnet. Furthermore, the magnetic component 52 and the front panel 31 can be fixed together by adhesive bonding.

[0035] In addition, refer to Figure 4 As shown, the upper end of the front panel 31 is rotatably connected to the main body of the range hood, and the magnetic suction member 52 is fixed to the inner side of the lower end of the front panel 31 so that the lower end of the front panel 31 is magnetically connected to the main body of the range hood. Thus, the upper side of the front panel 31 is connected by a rotating assembly 40, and the lower end of the front panel 31 is connected to the main body of the range hood through the magnetic suction member 52. When the user applies a pulling force to the lower end of the front panel 31, and when the pulling force is greater than the magnetic attraction between the magnetic suction member 52 and the main body of the range hood, the magnetic suction member 52 and the main body of the range hood separate from each other; then, when a pulling force is applied to the front panel 31, the front panel 31 rotates and opens under the action of the rotating assembly 40, thereby facilitating user maintenance and cleaning.

[0036] Furthermore, the range hood 100 can also be equipped with a second magnetic suction component, which is fixed to the main body of the range hood. The magnetic suction component 52 and the second magnetic suction component selectively engage. Thus, when the front panel 31 is in its original working state, the front panel 31 and the main body of the range hood are magnetically connected by the magnetic suction component 52 and the second magnetic suction component. This makes the engagement between the lower end of the front panel 31 and the main body of the range hood more stable, further preventing the lower end of the front panel 31 from separating from the main body of the range hood in its original working state.

[0037] The second magnetic component can be a powerful neodymium iron boron permanent magnet. Furthermore, the second magnetic component and the front plate 11 can be fixed together by adhesive bonding.

[0038] Furthermore, a first receiving groove is provided on the front panel 31, and the magnetic suction member 52 is disposed in the first receiving groove, so that the magnetic suction member 52 and the front panel 31 are flush, which can improve the surface uniformity of the range hood 100.

[0039] According to another optional embodiment of the present invention, the range hood 100 further includes: a plurality of first brackets, which are spaced apart on the side of the front panel 31 facing the front plate 11; each first bracket is provided with a first snap-fit ​​portion, and the front plate 11 is provided with a second snap-fit ​​portion, the first snap-fit ​​portion and the second snap-fit ​​portion engaging. Thus, the front panel 31 and the front plate 11 can be engaged through the first snap-fit ​​portion and the second snap-fit ​​portion, thereby facilitating the disassembly and assembly of the front panel 31, and consequently facilitating user maintenance and cleaning.

[0040] Specifically, a first bracket is fixed on the front panel 31, and a first snap-fit ​​part is provided on the first bracket, and a second snap-fit ​​part is provided on the front plate 11, so that the first bracket and the front plate 11 can be snap-fitted together through the first snap-fit ​​part and the second snap-fit ​​part.

[0041] The first snap-fit ​​part can be a snap hook, and the second snap-fit ​​part can be a snap slot.

[0042] Furthermore, the first bracket and the front panel 31 can be fixed together by adhesive bonding.

[0043] In addition, you can remove the front panel 31 by holding both sides of it with your hands and applying slight force to one side in the width direction. This makes it very easy to clean thick grease stains, and you can directly take the front panel 31 to the sink for a thorough scrubbing.

[0044] According to another optional embodiment of the present invention, the range hood 100 further includes: a second magnetic suction assembly, the second magnetic suction assembly including: a plurality of third magnetic suction elements and a plurality of fourth magnetic suction elements, the plurality of third magnetic suction elements are fixed on the side of the front panel 31 facing the front plate 11 and are spaced apart from each other, the plurality of fourth magnetic suction elements are fixed on the side of the front plate 11 facing the front panel 31 and are spaced apart from each other, and the second magnetic suction elements and the second magnetic suction elements selectively attract each other.

[0045] In addition, the front panel 31 can be removed by simply holding both sides with your hands and applying a little force, making it very easy to clean thick grease. The front panel 31 can then be taken directly to the sink for a thorough scrubbing.

[0046] The third and fourth magnetic components can be powerful neodymium iron boron permanent magnets.

[0047] Furthermore, the third magnetic component and the front panel 31 can be fixed by adhesive bonding, and the fourth magnetic component and the front panel 11 can be fixed by adhesive bonding.

[0048] Furthermore, the front panel 31 and the front plate 11 are connected by a second magnetic component, which is simpler and more precise. Due to the attraction of the third and fourth magnetic components, when installing the front panel 31, it will be automatically guided to the correct position and snap into place with a "click", avoiding the trouble of misaligning the holes with traditional screws.

[0049] A side-suction vent structure 32 is provided on the lower side of the main body of the range hood. The side-suction vent structure 32 is located on the lower side of the front panel 31, and a side-suction vent 323 communicating with the smoke collection chamber 10 is provided on the side-suction vent structure 32. That is, a side-suction vent structure 32 is provided on the main body of the range hood, and a side-suction vent 323 communicating with the smoke collection chamber 10 is provided on the side-suction vent structure 32. In this way, when the range hood 100 is working, a negative pressure is generated at the side-suction vent 323. The side-suction vent 323 is close to the stove. When the oil fumes are generated at a relatively fast speed, a large amount of oil fumes rush to the side-suction vent 323 and are sucked into the smoke collection chamber 10 by the side-suction vent 323.

[0050] The main body of the smoke hood is provided with a front plate 11 located in front of the smoke collection chamber 10. That is, a front plate 11 is provided in front of the smoke collection chamber 10. The front plate 11 can support the front panel 31. That is, when the front panel 31 is in the position of closing the smoke collection chamber 10, the front panel 31 abuts against the front plate 11.

[0051] In addition, the front panel 11 is provided with a side air intake structure 32 located below the front panel 31. By providing the side air intake structure 32 below the front panel 31 on the front panel 11, the front panel 11 not only has the function of supporting the front panel 31, but also has the function of smoke intake.

[0052] Furthermore, the front panel 11 is provided with an opening 12 that communicates with the smoke collection chamber 10, and the front panel 31 is covered at the opening 12. When it is necessary to clean the inner wall of the smoke collection chamber 10 and the front panel 31, the opening 12 can be exposed by rotating and opening the front panel 31.

[0053] Furthermore, a connecting portion is provided at the upper edge of the front panel 11, and the lower end of the front panel 31 is connected to the connecting portion. That is, a connecting portion is provided at the upper end of the front panel 11, so that the lower end of the front panel 31 can be detachably connected to the connecting portion. For example, when the front panel 31 is in the closed position, the front panel 31 is connected to the connecting portion; or, for example, when the front panel 31 is in the open position, the front panel 31 is separated from the connecting portion to facilitate the rotation and opening of the front panel 31.

[0054] Specifically, the lower end of the front panel 31 is attracted to the connecting part by a magnetic attachment 52.

[0055] In addition, since the side air intake 323 is inclined from bottom to top and backward, the oil fumes can flow upward through the side air intake 323 and continue to flow into the smoke collection chamber 10, thereby avoiding the influence of the guide plate 32 on the process of oil fumes flowing into the smoke collection chamber 10 and ensuring the oil fume suction effect of the range hood 100.

[0056] Furthermore, a top-mounted air intake vent 21 is also provided on the top panel 20. Specifically, when the range hood 100 is working, negative pressure is generated at both the side intake vent 323 and the top intake vent 21. The side intake vent 323 is closer to the cooktop. When the oil fumes are generated quickly, a large amount of oil fumes rush towards the side intake vent 323. Some of the oil fumes are drawn into the smoke collection chamber 10 by the side intake vent 323. The oil fumes that cannot be drawn in time by the side intake vent 323 will flow upward along the front panel 31. After flowing to the top panel 20, the oil fumes will be drawn into the smoke collection chamber 10 by the top intake vent 21. In this way, the oil fumes flowing through the main body of the range hood can be fully drawn into the smoke collection chamber 10, reducing the escape of oil fumes, thereby improving the oil fume extraction effect of the range hood 100 and improving the user experience.

[0057] Combination Figures 1-5 As shown, a cavity 23 is provided on the top plate 20, and multiple spaced-apart top suction ports 21 are provided on the cavity 23. There is one cavity 23 and one, two, or more top suction ports 21. The cavity 23 can collect the oil fumes flowing to the top plate 20, thereby increasing the difficulty for the oil fumes to escape from the top plate 20 and prolonging the time for the oil fumes to flow along the top plate 20, thus providing sufficient time for the top suction ports 21 to fully draw the oil fumes into the smoke collection chamber 10.

[0058] That is, the cavity 23 can concentrate the oil fumes flowing into the cavity 23, thereby increasing the difficulty for the oil fumes to escape from the cavity 23 and prolonging the time for the oil fumes to flow along the cavity 23, thus providing enough time for the top suction port 21 to fully suck the oil fumes into the smoke collection chamber 10.

[0059] Furthermore, such as Figure 4 and Figure 5 As shown, a guide plate 22 is provided on the side of the top air intake 21 facing the smoke collection chamber 10, and the guide plate 22 is inclined in the direction away from the front panel 31. In this way, the guide plate 22 on the top air intake 21, which is inclined in the direction away from the front panel 31, can guide the oil fumes, making the oil fumes flow more smoothly in the smoke collection chamber 10. On the other hand, since the guide plate 22 blocks the top air intake 21, it can prevent the oil droplets condensed on the top wall of the smoke collection chamber 10 from dripping directly down the top air intake 21.
