[0002] The function of the range hood is to discharge the oil fume generated during cooking in the kitchen to the outside, purify the kitchen air environment, and reduce the harm of oil fume to the human body. There are many types of range hoods, including side-suction range hoods, island-style range hoods, 7-shaped range hoods, etc. Among them, compared with the side-suction range hoods in the related art, the 7-shaped range hood can effectively reduce the occupation of the user's operating space, and can use larger steamers, woks, etc. In addition, the fan is placed on the top and blocked by the cabinet, which can also effectively reduce noise, making it widely used in people's lives. However, due to the "7" shape, the smoke collecting plate on the top of the 7-shaped range hood in the related art cannot have a large deep-drawn cavity like the top smoke extractor, and is usually set as multiple flat plates connected in sequence. Therefore, the smoke collecting effect on the top is poor, especially when the oil fume is large, the oil fume will likely rush out directly from the top plane, causing the oil fume to escape.

[0033] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of 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 violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0034] See also Figures 1 to 4 , Figure 1 A structural diagram of a range hood according to an embodiment of the present application is shown. Figure 2 Shows Figure 1 Front view of the structure shown. Figure 3 Shows Figure 1 The structure shown is a structural diagram after the condensation plate 113 is removed. Figure 4 Shows Figure 1A cross-sectional structural diagram of the structure shown. An embodiment of the present application provides a smoke collecting hood 10 of a range hood, the smoke collecting hood 10 comprising a smoke collecting plate 111, the smoke collecting plate 111 is provided with a smoke collecting cavity 1111 recessed toward the interior of the smoke collecting hood 10 and a mounting portion 1112 located inside the smoke collecting cavity 1111 and used to install a lighting fixture 112. The mounting portion 1112 protrudes from the top wall 1118 of the smoke collecting cavity 1111 in a direction away from the interior of the smoke collecting hood 10 to separate the smoke collecting cavity 1111 into two smoking areas 1113 arranged in sequence along the left and right directions of the smoke collecting hood 10. A plurality of first ventilation holes 1114 are formed on the cavity wall of each smoking area 1113, and at least one second ventilation hole 1115 located around the lighting fixture 112 is formed on the mounting portion 1112. The smoke collecting cavity 1111 is connected to the interior of the smoke collecting hood 10 through the first ventilation holes 1114 and the second ventilation holes 1115, respectively.

[0035] The smoke collecting hood 10 of the range hood described above, because the mounting portion 1112 protrudes from the top wall 1118 of the smoke collecting chamber 1111 in a direction away from the inside of the smoke collecting hood 10, the smoke collecting chamber 1111 is divided into two smoking areas 1113 arranged in sequence along the left and right directions of the smoke collecting hood 10, and each smoking area 1113 is provided with a plurality of first ventilation holes 1114 connected to the inside of the smoke collecting hood 10, so as to better match the double stoves and improve the smoke collection effect. In addition, because at least one second ventilation hole 1115 located around the lighting fixture 112 is formed on the mounting portion 1112, the smoke collecting chamber 1111 is also connected to the inside of the smoke collecting hood 10 through the second ventilation hole 1115, which can effectively absorb the oil smoke floating near the lighting fixture 112, effectively improving the smoking effect and reducing the oil smoke escape phenomenon.

[0036] See also Figure 2 and Figure 3 In some embodiments, the mounting portion 1112 is located in the middle of the smoke collecting chamber 1111, so that the two smoking areas 1113 have the same volume size, thereby better matching the double stove.

[0037] See also Figure 2 and Figure 3 In some embodiments, the shapes of the first ventilation holes 1114 and the second ventilation holes 1115 are independently set and flexibly adjusted according to actual needs, including but not limited to waist-shaped holes, strip holes, circular holes, elliptical holes or polygonal holes, etc.; in some embodiments, the number of rows of the first ventilation holes 1114 and the second ventilation holes 1115 includes but is not limited to one row, two rows or more rows.

[0038] In some embodiments, the second ventilation hole 1115 can be one or more; the second ventilation hole 1115 can be arranged at various positions such as the left side, right side, top side, and bottom side of the mounting portion 1112 according to actual needs, and is not limited here.

[0039] In one embodiment, a plurality of second ventilation holes 1115 are provided and arranged at opposite sides of the mounting portion 1112 along the left and right directions thereof. In this way, compared with the method of arranging the second ventilation holes 1115 at the upper side or the lower side of the mounting portion 1112, a better oil guiding effect can be achieved to prevent the defect of oil dripping onto the stove surface.

[0040] See also Figure 2 and Figure 3 In some embodiments, the housing of the lighting fixture 112 includes but is not limited to being embedded and fixed in the mounting portion 1112. In addition, the outer wall surface of the housing is set to be a plane, and specifically, for example, is flush with the outer wall surface of the mounting portion 1112, so that the cleaning of the mounting portion 1112 can be facilitated. Of course, the outer wall surface of the housing can be set to be a non-planar surface, and for example, protrude from the outer wall surface of the mounting portion 1112, or be recessed toward the inside of the smoke hood 10, etc., which can be flexibly adjusted and set according to actual needs.

[0041] See also Figure 4 and Figure 5 In one embodiment, the distance S1 between the peripheral contour of the smoke collecting chamber 1111 and the top wall 1118 of the smoke collecting chamber 1111 is greater than the distance S2 between the outer surface of the mounting portion 1112 and the top wall 1118 of the smoke collecting chamber 1111. In other words, the height position of the peripheral contour of the smoke collecting chamber 1111 is lower than the height position of the outer surface of the mounting portion 1112. In this way, the smoke collection effect can be improved, and the smoke can be prevented from easily impacting the mounting portion 1112 and floating away when the distance S1 ≤ S2.

[0042] The bottom end of the smoke collecting plate 111 in the related art is connected to the top end of the condensation plate 113 located below it. The oil stains on the surface of the smoke collecting plate 111 can easily flow along the connection between the two to the surface of the condensation plate 113 below, forming oil flow marks, resulting in poor product appearance quality.

[0043] See also Figure 2 , Figure 5 and Figure 6In one embodiment, the smoke collecting hood 10 further includes a condensation plate 113 disposed below the smoke collecting plate 111 and arranged at an angle with the smoke collecting plate 111. The angle between the condensation plate 113 and the smoke collecting plate 111 includes, but is not limited to, for example, 90° to 150°, and the specific size can be flexibly adjusted and set according to actual needs. The rear end 1116 of the smoke collecting chamber extends to the rear of the condensation plate 113, and the top wall 1118 of the smoke collecting chamber 1111 cooperates with the top of the condensation plate 113 to form a ventilation gap 1117. The rear end 1116 of the smoke collecting chamber, i.e., the lower end or bottom end of the smoke collecting chamber 1111, extends to the rear of the condensation plate 113, so as to guide the oil stains to the back of the condensation plate 113, thereby preventing the oil stains from falling to the outer surface of the condensation plate 113 and causing product appearance quality defects. In addition, the ventilation gap 1117 is located at the angle between the condensation plate 113 and the top wall 1118 of the smoke collecting chamber 1111. When the oil smoke rises to this angle, it will be instantly sucked into the range hood. In addition, compared with the smoke collecting chamber 1111 in the related art, the volume size of the smoke collecting area is increased in this embodiment because it extends to the rear of the condensation plate 113, which effectively improves the smoking effect.

[0044] See also Figure 6 In one embodiment, the minimum distance D between the top of the condensation plate 113 and the top wall 1118 of the smoke collecting chamber 1111 is 10 mm to 50 mm. Specifically, the distance D includes but is not limited to 10 mm, 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 50 mm, etc. In this way, the size of the distance D is set appropriately. On the one hand, the distance D is large, which makes it easy to enter the air. On the other hand, the distance D is not too large to reduce the air intake effect of the air inlet 18 at the bottom.

[0045] Of course, as some optional solutions, the spacing D can also be set to any value less than 10 mm and greater than 50 mm. It can be flexibly adjusted and set according to actual needs and is not limited here.

[0046] See also Figures 4 to 6 , Figures 4 to 6 The arrows also indicate the flow path of the smoke when the range hood is working. A part of the smoke rising from the pot is sucked into the smoke collecting hood by the smoke inlet at the bottom of the range hood, and the other part of the smoke that continues to rise will be blocked by the smoke collecting plate 111, collected by the smoke collecting chamber 1111, and sucked into the smoke collecting hood from the first ventilation hole 1114, the second ventilation hole 1115 and the ventilation gap 1117 of the smoke collecting chamber 1111, accelerated by the fan system, separated from the oil dirt by the oil net 16, and finally discharged from the check valve.

[0047] See also Figure 1 and Figure 5In one embodiment, the smoke collecting hood 10 further includes a back panel 12 and an oil cup 13 connected to the bottom of the back panel 12. The surface where the smoke collecting plate 111 is located is set at an angle to the back panel 12, and the rear end height position of the smoke collecting plate 111 is lower than the front end height position of the smoke collecting plate 111. In other words, the smoke collecting plate 111 is arranged obliquely relative to the back panel 12, and presents a posture of high front and low back. In this way, the oil stains on the surface of the smoke collecting plate 111 can flow into the interior of the smoke collecting hood 10 under the action of its own gravity and then be collected by the oil cup 13, thereby preventing the oil stains from falling onto the outer surface of the condensation plate 113 and causing product appearance quality defects, and preventing the oil stains from falling directly onto the stove surface and causing pollution.

[0048] See also Figure 1 and Figure 5 In some embodiments, the smoke collecting hood 10 further includes two side panels 14 connected to the left and right opposite sides of the back panel 12 and a top panel 15 connected to the top of the back panel 12. The smoke collecting plate 111 is connected to the two side panels 14 and the top panel 15 respectively. Among them, the surface where the condensation plate 113 is located is arranged at an angle with the back panel 12. Optionally, the angle between the condensation plate 113 and the back panel 12 is smaller than the angle between the smoke collecting plate 111 and the back panel 12. In some examples, the angle a formed by the smoke collecting plate 111 and the back panel 12 includes but is not limited to being greater than or equal to 45° and less than 90°, specifically for example 45°, 60°, 65°, 70°, 75°, 80° or 85°, etc. In addition, the angle b formed by the condensation plate 113 and the back panel 12 includes but is not limited to being greater than 0° and less than 45°, specifically for example 5°, 10°, 15°, 20°, 25°, 30°, 35°, 43°, etc.

[0049] See also Figure 3 and Figure 5 In one embodiment, the smoke collecting hood 10 further includes an oil net 16 connected between the rear end of the smoke collecting plate 111 and the back panel 12. In this way, the oil smoke entering from the air inlet 18 at the bottom and the oil smoke entering from the ventilation gap 1117 can be condensed, and the condensed oil can be directed to the back panel 12 and flow along the back panel 12 to the inside of the oil cup 13; in addition, the oil on the smoke collecting plate 111 can be directed to the back panel 12. In addition, it plays a safety protection role to prevent users from reaching out to touch the dangerous parts inside the range hood; in addition, it can also separate the bottom air intake airflow to reduce wind noise.

[0050] Specifically, the oil net 16 extends from one side of the smoke collecting plate to the other side along the left-right direction of the smoke collecting hood 10, that is, the length of the oil net 16 along the left-right direction is adapted to the length of the smoke collecting plate 111 along the left-right direction, so that each position of the smoke collecting plate 111 along the left-right direction can filter oil and guide oil.

[0051] In some embodiments, when the oil smoke contacts the cavity wall of the smoke collecting cavity 1111, some oil will condense on the cavity wall of the smoke collecting cavity 1111. And because the smoke collecting plate 111 has a certain angle with the horizontal direction, it is high in the front and low in the back, so that under the action of gravity, the oil condensed on the cavity wall of the smoke collecting cavity 1111 flows from high to low, and the oil flowing to the bottom of the smoke collecting plate 111 further flows along the oil net 16 to the back panel 12, and then flows into the oil cup 13. Because the smoke collecting cavity 1111 is stretched to the rear of the condensation plate 113, the oil in the smoke collecting cavity 1111 will not flow to the outer surface of the condensation plate 113, making the outer surface cleaner and tidier.

[0052] It should be noted that the oil net 16 can be detachably mounted on the smoke collecting plate 111 or welded and fixed on the smoke collecting plate 111. The specific configuration can be flexibly configured according to actual needs and is not limited here.

[0053] See also Figure 3 and Figure 5 In one embodiment, a plurality of first connection parts 161 are provided at the front end of the oil net 16, and each first connection part 161 is connected and fixed to the rear end of the smoke collecting plate 111 by a fastener. In addition, second connection parts 162 are provided on the left and right opposite sides of the oil net 16, and the second connection parts 162 are connected to the back panel 12. Specifically, the smoke collecting hood 10 also includes two guide members 17 installed on the left and right opposite sides of the back panel 12, and each guide member 17 is provided with a snap-on hole 171, and each second connection part 162 is set as a snap-on part and is correspondingly snap-on and fixed in the snap-on hole 171. Optionally, the snap-on part includes but is not limited to a hook formed by bending the mesh wire of the oil net 16. Thus, during the installation process, the oil net 16 can be initially fixed by firstly clamping and fixing the second connecting parts 162 on the left and right opposite sides into the two clamping holes 171, and then the first connecting parts 161 are respectively connected and fixed to the rear end of the smoke collecting plate 111 by fasteners, so that the oil net 16 is stably installed inside the smoke collecting hood 10. Since the first connecting parts 161 are all located in the same direction, the disassembly and assembly operation can be facilitated.

[0054] In some embodiments, fasteners include, but are not limited to, screws, pins, rivets, and the like.

[0055] In summary, the smoke collecting hood 10 of the range hood in this embodiment has at least the following advantages: by using this technical solution, the smoke collecting performance of the top-side double-suction type can be effectively enhanced, the distribution of the smoke airflow is optimized, and the smoking effect is improved. In addition, the oil line condensed on the range hood is optimized, so that the oil on the smoke collecting chamber 1111 can flow into the interior of the range hood under the action of gravity and reach the oil cup 13. In addition, the oil is prevented from flowing to the outer surface of the condensation plate 113, reducing the pollution of the outer surface of the condensation plate 113, which is conducive to keeping the range hood clean.

[0056] See also Figures 1 to 4 In one embodiment, a range hood, including but not limited to a 7-shaped range hood and a side-suction range hood, includes the fume hood 10 of the range hood of any of the above embodiments. In addition, the range hood also includes a bellows 20 connected to the top of the fume hood 10, and a centrifugal fan 21 is arranged inside the bellows 20. When the centrifugal fan 21 is working, a negative pressure is formed inside the fume hood 10, so that the oil fume in the external environment enters the inside of the fume hood 10 through the air inlet 18 at the bottom and the first ventilation, second ventilation and ventilation gap 1117.

[0057] The above-mentioned range hood, because the mounting portion 1112 protrudes from the top wall 1118 of the smoke collecting chamber 1111 in a direction away from the inside of the smoke collecting hood 10, the smoke collecting chamber 1111 is divided into two smoking areas 1113 arranged in sequence along the left and right directions of the smoke collecting hood 10, and each smoking area 1113 is provided with a plurality of first ventilation holes 1114 connected to the inside of the smoke collecting hood 10, so as to better match the double stoves and improve the smoke collection effect. In addition, because at least one second ventilation hole 1115 located around the lighting fixture 112 is formed on the mounting portion 1112, the smoke collecting chamber 1111 is also connected to the inside of the smoke collecting hood 10 through the second ventilation hole 1115, which can effectively absorb the oil smoke floating near the lighting fixture 112, effectively improving the smoking effect and reducing the oil smoke escape phenomenon.
