[0002] A range hood, also known as an oil fume extractor, is a kitchen appliance for purifying the kitchen environment. It is installed above the kitchen stove and can quickly extract the waste generated by the stove combustion and the harmful oil fume produced during the cooking process and discharge it outdoors.

[0035] To make the above objects, features, and advantages of the present application more obvious and understandable, the following will describe the detailed implementation manners of the present application in conjunction with the accompanying drawings. Many specific details are set forth in the following description to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0036] As described in the background art, for a range hood in which the panel is inclined relative to the back panel of the smoke collecting hood, there is a problem that the oil fume cannot be well sucked into the interior of the range hood. After research by the inventor, it is found that the reason for this problem is that since the space size at the end of the chamber of the smoke collecting hood near the fan is larger than the space size at the bottom of the chamber of the smoke collecting hood, the suction capacity at the air inlet of the smoke collecting hood will be reduced, resulting in the oil fume not being well sucked into the interior of the range hood.

[0037] Based on the above reasons, the present application provides a range hood and its panel assembly, which can effectively improve the oil fume suction capacity of a range hood in which the panel is inclined relative to the back panel of the smoke collecting hood.

[0038] Refer to Figure 1 And Figure 2 , Figure 1 And Figure 2Structural diagrams of the panel assembly of a range hood according to an embodiment of the present application are respectively shown in the open state and the closed state. A panel assembly 10 of a range hood provided by an embodiment of the present application is disposed on a smoke collecting hood 20 of the range hood, and an air inlet is formed between the bottom end of the panel assembly and the bottom of the smoke collecting hood. It can be understood that the panel assembly may only have a closed state, or may have both open and closed states. In this embodiment, the panel assembly has both open and closed states. When it is in the open state, it is convenient to clean the interior of the range hood; when it is in the closed state, it can shield the interior of the smoke collecting hood and is also convenient for sucking oil fumes. In addition, please refer to Figure 1 , Figure 2 , Figures 4 to 6 . The panel assembly 10 of the range hood includes: a panel 11 and a flow guiding member 12. The panel 11 is inclined with respect to the back plate 21 of the smoke collecting hood 20, and the distance between the top end of the panel 11 and the back plate 21 is greater than the distance between the bottom end of the panel 11 and the back plate 21. The flow guiding member 12 is connected to the inner side wall of the panel 11, and the flow guiding member 12 is provided with a flow guiding wall 121 disposed at an angle with the panel 11. The distance S between the flow guiding wall 121 and the panel 11 increases in the direction of the air flow, so that the difference between the distance between the top end of the flow guiding wall 121 and the back plate 21 and the distance between the bottom end of the flow guiding wall 121 and the back plate 21 is reduced.

[0039] It should be noted that the inner side wall of the panel 11 refers to the side facing the chamber of the smoke collecting hood 20. On the contrary, the outer side wall of the panel 11 refers to the side wall opposite to the inner side wall, that is, the side facing the user. The panel 11 includes, but is not limited to, a glass plate, which plays a decorative role. In addition, when in the closed state, the panel 11 is inclined with respect to the back plate 21. Compared with the setting method parallel to the back plate 21, it can be closer to the oil fumes, form a pressure on the surface, so the adsorption effect is better, and more oil fumes can be adsorbed into the smoke collecting hood 20.

[0040] For the above-mentioned panel assembly 10 of the range hood, a flow guiding member 12 is disposed on the inner side wall of the panel 11, and the flow guiding member 12 is provided with a flow guiding wall 121 disposed at an angle with the panel 11. Since the distance between the flow guiding wall 121 and the panel 11 increases in the direction of the air flow, the difference between the distance between the top end of the flow guiding wall 121 and the back plate 21 and the distance between the bottom end of the flow guiding wall 121 and the back plate 21 is reduced, so that the flow guiding wall 121 is parallel or nearly parallel to the back plate 21. Furthermore, the distance S between different parts of the flow guiding wall 121 and the back plate 21 in the vertical direction is equal or almost equal. In this way, the pressure at different parts is stable, the oil fume suction pressure at the air inlet is guaranteed, the suction capacity is improved, the oil fumes can be completely sucked away when rising to the air inlet, and the effect of flowing upward to the fan is better, meeting the smoking requirement and preventing oil fumes from escaping.

[0041] Among them, being close to parallel means that they appear parallel to each other to the naked eye. When the angle between the diversion wall 121 and the back plate 21 is relatively large, the top of the diversion wall 121 is close to the back plate 21. In this way, although the flow rate of the flue gas at the smoke inlet can be increased and the suction capacity of the range hood can be enhanced, the noise will also increase synchronously. When the angle between the diversion wall 121 and the back plate 21 is relatively small, the top of the diversion wall 121 is close to the front panel 11. In this way, although the noise can be reduced, the flow rate of the flue gas at the smoke inlet will also decrease synchronously, reducing the suction capacity of the range hood. Preferably, the angle between the diversion wall 121 and the back plate 21 is allowed to be within, for example, ±5°, specifically, for example, -5°, -4°, -3°, -1°, 0°, 1°, 2°, 3°, 4° or 5°, etc. Specifically, the angle between the diversion wall 121 and the back plate 21 is, for example, 0°, that is, the diversion wall 121 is parallel to the back plate 21. In other words, the diversion wall 121 is arranged in the vertical direction. It can be understood that

[0042] It should be noted that there are many connection methods between the diversion member 12 and the front panel 11, including but not limited to being fixedly connected by various fasteners such as pins, rivets, screws, bolts, and snap connectors, or it can also be, for example, adhesively bonded and fixed, or it can also be, for example, welded, integrally formed, etc. The specific connection method can be flexibly adjusted and set according to actual requirements.

[0043] Please refer to Figure 1 and Figure 2 , in some embodiments, the top of the front panel 11 is, for example, rotatably connected to the smoke collecting hood 20, and the front panel 11 is further provided with a snap member 111 that is snap-fitted with the smoke collecting hood 20. When the driving mechanism of the range hood drives the front panel 11 to rotate and open, the snap member 111 of the front panel 11 is separated from the smoke collecting hood 20 and rotates to a suitable angular position; when the driving mechanism of the range hood drives the front panel 11 to rotate and close, the front panel 11 closes on the smoke collecting hood 20 and is snap-fixed to the smoke collecting hood 20 through the snap member 111.

[0044] In one embodiment, the diversion member 12 includes but is not limited to being a die-cast part or a sheet metal part. In addition, the diversion member 12 is formed with a recess facing the front panel 11 and encloses a cavity with the front panel 11. In this way, the diversion member 12 is processed by die-casting integral molding or sheet metal integral molding, which has a high processing efficiency and low production cost. In addition, since the diversion member 12 is formed with a recess, this can save materials and reduce material costs.

[0045] Please refer to Figure 4 and Figure 5, in one embodiment, one or more corrugated structures 1211 are formed on the flow guide wall 121. Thus, by providing the corrugated structures 1211 on the flow guide wall 121, the structural strength of the flow guide wall 121 can be increased. The more the number of the corrugated structures 1211, the more obvious the increase in the structural strength of the flow guide member 12 will be, thereby preventing resonance noise from being generated and reducing the noise.

[0046] Of course, as some alternative solutions, when the structural strength of the flow guide member 12 is relatively large, the number of the corrugated structures 1211 provided can be reduced, or even the corrugated structures 1211 do not need to be formed.

[0047] Among them, the corrugated structure 1211 can be either a convex hull recessed toward the inside of the cavity or a convex hull protruding toward the outside of the cavity, and can be specifically adjusted and set flexibly according to actual requirements.

[0048] In a specific embodiment, the corrugated structure 1211 is a convex hull recessed toward the inside of the cavity. Thus, compared with the way that the convex hull protrudes toward the outside of the cavity, the convex hull will not interfere with the upward flow of the oil fume airflow entering the inside of the smoke collecting hood 20 from the air inlet.

[0049] In one embodiment, the outer contour of the corrugated structure 1211 includes but is not limited to regular shapes such as rectangular, circular or oval, and other irregular shapes. In addition, a plurality of corrugated structures 1211 are arranged at intervals in the left-right direction of the range hood. Thus, two adjacent corrugated structures 1211 can cooperate to form a bead, and the bead can strengthen the structural strength of the flow guide member 12.

[0050] Please refer to Figure 4 , in one embodiment, the flow guide member 12 includes a main body structure 122 formed with a recess and a flanging 123 circumferentially arranged around the main body structure 122, and the flanging 123 is fixedly attached to the panel 11.

[0051] Please refer to Figure 7 , in one embodiment, a plurality of sound absorption holes 1212 are formed on the flow guide wall 121. Specifically, the plurality of sound absorption holes 1212 are, for example, arranged in one row, two rows, or more rows, and can also be, for example, arranged in an array, or arranged in other irregular ways, and can be specifically adjusted and set flexibly according to actual requirements, and are not limited herein. Thus, during the process that the oil fume airflow flows from the air inlet into the inside of the smoke collecting hood 20, the sound absorption holes 1212 play an effective role in reducing noise. Especially for users facing the panel assembly 10, under the noise reduction effect of the sound absorption holes 1212, the noise felt by the users from the front of the range hood is greatly reduced.

[0052] In one embodiment, the panel assembly 10 of the range hood further includes a sound-absorbing material. The sound-absorbing material includes, but is not limited to, sound-absorbing cotton, etc. The sound-absorbing material can be filled inside the cavity, or can be attached to the inner side surface of the flow guide wall 121, or can be attached to the entire inner wall of the cavity. Specifically, it can be flexibly adjusted and set according to actual needs, and will not be limited here. In this way, under the dual noise reduction effects of the sound-absorbing holes 1212 and the sound-absorbing material, the noise can be effectively reduced and noise isolation can be achieved.

[0053] Please refer to Figure 1 With Figure 2 , in one embodiment, a range hood includes the panel assembly 10 of the range hood in any of the above embodiments, and further includes a smoke collecting hood 20. The panel assembly 10 is disposed on the smoke collecting hood 20, and an air inlet is formed between the bottom end of the panel assembly 10 and the bottom of the hood 10.

[0054] For the above-mentioned range hood, a flow guide member is provided on the inner side wall of the panel. The flow guide member is provided with a flow guide wall that forms an angle with the panel. Since the distance between the flow guide wall and the panel increases in the direction of the airflow, the difference between the distance between the top end of the flow guide wall and the back plate and the distance between the bottom end of the flow guide wall and the back plate decreases, so that the flow guide wall 121 and the back plate 21 are in a parallel or nearly parallel state. Furthermore, the distances S between different parts of the flow guide wall 121 and the back plate 21 in the vertical direction are equal or almost equal. In this way, the pressure at different parts is stable, the oil fume suction pressure at the air inlet is guaranteed, the suction capacity is improved, and the oil fume can be completely sucked away when it rises to the air inlet, and the effect of flowing upward to the fan will be better, meeting the smoking requirement and preventing oil fume leakage.

[0055] Please refer to Figure 3 , in one embodiment, the range hood further includes a box body 30 provided on the top of the smoke collecting hood 20 and a fan provided inside the box body 30. Both the box body 30 and the smoke collecting hood 20 are provided with docking interfaces and are docked and communicated with each other. The range hood further includes a first smoke guide plate 40 and a second smoke guide plate 50 provided inside the smoke collecting hood 20. The top ends of the first smoke guide plate 40 and the second smoke guide plate 50 are respectively connected to the left and right opposite side walls of the docking interface, and the bottom ends of the first smoke guide plate 40 and the second smoke guide plate 50 respectively extend obliquely toward the left and right opposite side walls of the smoke collecting hood 20. The flow guide wall 121 is located in the interval area between the first smoke guide plate 40 and the second smoke guide plate 50. In this way, under the auxiliary smoke guiding effects of the first smoke guide plate 40 and the second smoke guide plate 50, the oil fume path is optimized, the internal air flow path is smoother, the generation of air flow collision noise and vortex noise is avoided, and the noise is greatly reduced.
