Description

Technical Field

[0001] This utility model relates to the field of range hood technology, and in particular to an oil fume collection device and a range hood. Background Technology

[0002] In normal cooking scenarios, existing range hoods are sufficient to effectively meet most usage needs. However, in high-intensity cooking scenarios, due to the sharp increase in the amount of cooking fumes produced, existing range hoods may still experience fumes escaping during operation, resulting in some fumes not being captured and purified in a timely manner.

[0003] In existing oil fume purification technologies, traditional solutions for improving particulate matter capture efficiency under extreme conditions primarily focus on optimizing the internal flow field, mainly by enhancing fan performance and increasing the maximum airflow of the range hood. However, limited by the aerodynamic characteristics of the fans, the current range hood's airflow increase has reached a physical bottleneck. Under the same airflow conditions, how to significantly improve the range hood's particulate matter capture efficiency by optimizing its external flow field characteristics has become a topic worthy of in-depth research in the field of oil fume purification technology.

[0004] The external airflow characteristics of a range hood are determined by its external structure. Existing range hoods include a smoke collection hood, which consists of a main panel and side panels on both sides of the main panel. The hood contains a smoke collection chamber, and the air inlet is usually located on the main panel. Cooking fumes are drawn into the smoke collection chamber through the air inlet on the main panel. However, under high-intensity cooking conditions, the amount of cooking fumes is large, and the air inlet on the main panel alone is insufficient to capture the high volume of fumes. Some fumes easily escape from areas other than the air inlet on the main panel, resulting in poor fume extraction. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of existing range hoods, such as easy escape of oil fumes and poor oil fume extraction effect, and to provide an oil fume collection device and a range hood.

[0006] The present invention solves the above-mentioned technical problems through the following technical solution:

[0007] This utility model provides an oil fume collection device for use in a range hood. The oil fume collection device includes a fume collection hood with a fume collection chamber inside. The fume collection hood includes a main panel and side panels on both sides of the main panel. The main panel has a main air inlet. At least one side panel has at least one side air inlet and a side baffle movably connected to the side panel. The side air inlet communicates with the fume collection chamber. The side baffle is configured to selectively close or partially block the side air inlet according to the flow rate of the oil fumes, so that the oil fumes on the side enter the fume collection chamber from the side air inlet.

[0008] In this design, the range hood has a main air inlet on the main panel, through which most of the fumes are drawn in. In addition to the main air inlet, side baffles and side air inlets connecting to the smoke collection chamber are installed on the side panels. This allows fumes escaping from the main air inlet to be blocked by the side baffles and drawn into the smoke collection chamber through the side air inlets, improving the range hood's fume extraction efficiency. The side baffles are movably connected to the side panels. Depending on the amount of fumes, the side baffles can selectively close or partially block the side air inlets, allowing fumes from the side to enter the smoke collection chamber through them. When the amount of fumes is small, the main air inlet alone is sufficient for fume extraction, and the side air inlets do not need to be opened. When the amount of oil fumes is large, the side baffle partially blocks the side air inlet, allowing the oil fumes to be drawn into the fume hood through the side air inlet, preventing the oil fumes from escaping from both sides of the main panel and improving the oil fume extraction effect of the oil fume collection device under high-intensity working conditions.

[0009] Preferably, the side baffle includes a first part, which is rotatably connected to the side plate and is located above the side air inlet.

[0010] In this design, by rotatably connecting the first part to the side plate, the side baffle can rotate relative to the side plate, thereby closing or partially blocking the side air inlet. By positioning the first part above the side air inlet, the first part can prevent smoke escape, thereby allowing the smoke to be drawn into the side air inlet.

[0011] Preferably, the first part is configured to have an adjustable rotation angle relative to the side plate according to the amount of oil fumes.

[0012] In this solution, by setting the first part to be able to adjust the rotation angle of the first part relative to the side plate according to the amount of oil smoke, the first part can be adjusted to a more suitable rotation angle under different amounts of oil smoke, so that the oil smoke absorption effect is better under different amounts of oil smoke, and the oil smoke collection device is further improved.

[0013] Preferably, the side baffle further includes a second part, which is rotatably connected to the first part, and the second part is configured to adjust the rotation angle of the second part relative to the first part according to the flow direction of the oil fumes on the main panel.

[0014] In this solution, the side baffle also includes a second part, which is rotatably connected to the first part. By setting the second part to be able to adjust the rotation angle of the second part relative to the first part according to the flow direction of the oil fumes on the main panel, the side baffle can better block the escape of oil fumes in the flow direction of the main panel, thereby further improving the effect of blocking the escape of oil fumes.

[0015] Preferably, the range hood further includes a main baffle, which is rotatably connected to the main panel and located above the main air inlet, and the rotation angle of the second part is set to be able to rotate to be consistent with the extension direction of the main baffle.

[0016] In this solution, by setting the rotation angle of the second part to be able to rotate in the same direction as the extension of the main baffle, the second part and the main baffle can cooperate better, better prevent the oil fumes from escaping, and further improve the oil fume extraction effect of the oil fume collection device.

[0017] Preferably, the fume collection device further includes a main baffle, which is rotatably connected to the main panel and positioned above the main air inlet.

[0018] In this solution, a main baffle is installed on the main air inlet of the main panel. The main baffle can block the escape of oil fumes below the main panel, making it easier for oil fumes to be drawn into the main air inlet and reducing the amount of oil fumes escaping from the main panel. Through the cooperation of the main baffle and the side baffle, the oil fume extraction effect of the oil fume collection device can be further improved.

[0019] Preferably, in the height direction of the fume collection device, at least a portion of the side baffle and the main baffle are at the same height.

[0020] In this solution, by positioning at least a portion of the side baffle and the main baffle at the same height in the height direction of the fume collection device, the side baffle and the main baffle can better cooperate with each other, thereby further improving the fume extraction effect of the fume collection device.

[0021] Preferably, the side air inlet is located at one end of the side panel near the main panel.

[0022] In this design, by placing the side air inlet at the end of the side panel close to the main panel, the fumes that escape from both sides of the main panel can be quickly drawn into the side air inlet, further preventing the fumes from escaping from the side and further improving the fume extraction effect of the fume collection device.

[0023] Preferably, the fume collection device further includes a fume detection device, a controller, and a drive device. The controller is electrically connected to the fume detection device and the drive device. The fume detection device is used to detect the amount of fume and feed back the fume amount value to the controller. The controller is used to control the drive device to drive the side baffle to move according to the received fume amount value, so as to close or partially block the side air inlet.

[0024] In this solution, the smoke detection device is used to detect the amount of oil fumes and feed the oil fume value back to the controller. The controller controls the drive device to move the side baffle based on the received oil fume value, so as to close or partially block the side air inlet. Compared with manual adjustment, the above structure makes it easier to adjust the rotation angle of the side baffle and more accurate to adjust for different oil fume sizes, further improving the effect of preventing oil fume from escaping.

[0025] This utility model also provides a range hood, which includes the aforementioned oil fume collection device.

[0026] The positive and progressive effects of this utility model are as follows:

[0027] The range hood features a main air inlet on the main panel, drawing in most of the fumes. In addition to the main inlet, side baffles and side air inlets connected to the smoke collection chamber are installed on the side panels. This allows fumes escaping from the main inlet to be blocked by the side baffles and drawn into the smoke collection chamber through the side air inlets, improving the range hood's fume extraction efficiency. The side baffles are movably connected to the side panel. Depending on the amount of fumes, the side baffles can selectively close or partially block the side air inlets, allowing fumes from the sides to enter the smoke collection chamber through them. When the amount of fumes is small, the main air inlet is sufficient for extraction, and the side air inlets do not need to be opened. However, when the amount of fumes is large, the side baffles partially block the side air inlets, allowing fumes to be drawn into the smoke collection hood through them, preventing fumes from escaping from the sides of the main panel and improving the fume extraction efficiency under high-intensity operating conditions.

[0044] Part Two 520 Detailed Implementation

[0045] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the following embodiments.

[0046] This embodiment provides a range hood 100, which includes an oil fume collection device 200.

[0047] like Figures 1-4 As shown, the fume collection device 200 is used in the range hood 100. The fume collection device 200 includes a fume collection hood 300, and a fume collection chamber 330 is provided inside the fume collection hood 300. The fume collection hood 300 includes a main panel 310 and side panels 320 provided on both sides of the main panel 310. The main panel 310 is provided with a main air inlet 311. At least one side panel 320 is provided with at least one side air inlet 321 and a side baffle 500 movably connected to the side panel 320. The side air inlet 321 communicates with the fume collection chamber 330. The side baffle 500 is configured to selectively close the side air inlet 321 or partially block the side air inlet 321 according to the flow rate of the fume, so that the fume on the side enters the fume collection chamber 330 from the side air inlet 321.

[0048] The range hood 100 has a main air inlet 311 on the main panel 310, through which most of the fumes are drawn in. In addition to the main air inlet 311, a side baffle 500 and a side air inlet 321 connecting to the smoke collection chamber 330 are provided on the side panel 320. This allows fumes escaping from the main air inlet 311 to be drawn into the smoke collection chamber 330 through the side air inlet 321, blocked by the side baffle 500, thus improving the fume extraction efficiency of the range hood 100. The side baffle 500 is movably connected to the side panel 320. Depending on the amount of fumes, the side baffle 500 can selectively close or partially block the side air inlet 321 to allow fumes from the side to enter the smoke collection chamber 330 through the side air inlet 321. When the amount of oil fumes is small, the main air inlet 311 is sufficient to achieve the desired fume extraction effect, and the side air inlets 321 do not need to be opened. However, when the amount of oil fumes is large, the side baffle 500 partially blocks the side air inlets 321, allowing the oil fumes to be drawn into the fume collection hood 300 through the side air inlets 321. This prevents the oil fumes from escaping from both sides of the main panel 310 and improves the fume extraction effect of the fume collection device 200 under high-intensity working conditions.

[0049] In this embodiment, the side baffle 500 partially obstructing the side air inlet 321 means that the side baffle 500 is located around the side air inlet 321, thereby guiding the fumes into the side air inlet 321 through the obstruction of the side baffle 500. In other embodiments, the side baffle 500 may also cover part of the side air inlet 321, which also conforms to the aforementioned situation where the side baffle 500 partially obstructs the side air inlet 321. Those skilled in the art can choose a suitable arrangement of the side baffle 500 according to the actual situation.

[0050] In this embodiment, the side baffle 500 is rotatably connected to the side plate 320. In other embodiments, the side baffle 500 may also be slidably connected to the side plate 320. The sliding movement of the side baffle 500 relative to the side plate 320 closes or partially blocks the side air inlet 321. Those skilled in the art can select a suitable connection method between the side baffle 500 and the side plate 320 according to actual needs. In this embodiment, the rotation angle range of the side baffle 500 is 90°. When the amount of oil fume is small, the side baffle 500 is vertically attached to the side plate 320 and blocks the side air inlet 321. When the amount of oil fume is large, the side baffle 500 can rotate to a horizontal direction to block the smoke. In other embodiments, those skilled in the art can select a suitable rotation angle range for the side baffle 500, as well as the specific rotation angle of the side baffle 500 for different amounts of oil fume.

[0051] like Figure 1 and Figure 2As shown, the side baffle 500 includes a first portion 510, which is rotatably connected to the side plate 320 and positioned above the side air inlet 321. By rotatably connecting the first portion 510 to the side plate 320, the side baffle 500 can rotate relative to the side plate 320, thereby closing or partially obstructing the side air inlet 321. By positioning the first portion 510 above the side air inlet 321, the first portion 510 can prevent smoke escape, thereby allowing smoke to be drawn into the side air inlet 321.

[0052] The first part 510 is configured to adjust the rotation angle of the first part 510 relative to the side plate 320 according to the amount of oil smoke, so that the first part 510 can be adjusted to a more suitable rotation angle under different amounts of oil smoke, so that the oil smoke absorption effect is better under different amounts of oil smoke, and further improves the oil smoke absorption effect of the oil smoke collection device 200.

[0053] The side baffle 500 also includes a second part 520, which is rotatably connected to the first part 510. The second part 520 is configured to adjust the rotation angle of the second part 520 relative to the first part 510 according to the flow direction of the oil fumes on the main panel 310, so that the side baffle 500 can better block the escape of oil fumes in the flow direction of the main panel 310, and further improve the effect of blocking the escape of oil fumes.

[0054] By configuring the side baffle 500 into two parts, a first part 510 and a second part 520, it is possible to block fumes according to different amounts of oil fumes. When the amount of oil fumes is large, only the first part 510 is opened, and the second part 520 is folded over the first part 510. If the amount of oil fumes increases further, the second part 520 can be opened on top of the first part 510 to further improve the oil fume blocking effect.

[0055] In this embodiment, the side baffle 500 is divided into two parts, with the second part 520 rotatably connected to the first part 510. In other embodiments, the side baffle 500 may also be divided into three or more parts. Those skilled in the art can select the appropriate number of side baffles 500 and the connection method of each part as needed.

[0056] The fume collection device 200 also includes a main baffle 400, which is rotatably connected to the main panel 310 and positioned above the main air inlet 311. By installing the main baffle 400 on the main air inlet 311 of the main panel 310, the main baffle 400 can prevent the escape of fumes below the main panel 310, making it easier for fumes to be drawn into the main air inlet 311 and reducing the amount of fumes escaping from the main panel 310. Through the cooperation of the main baffle 400 and the side baffle 500, the fume extraction effect of the fume collection device 200 can be further improved.

[0057] The rotation angle of the second part 520 is set to be able to rotate in the same direction as the extension of the main baffle 400, so that the second part 520 and the main baffle 400 can cooperate better, better prevent the oil fumes from escaping, and further improve the oil fume extraction effect of the oil fume collection device 200.

[0058] In the height direction of the fume collection device 200, at least a portion of the side baffle 500 and the main baffle 400 are at the same height, which enables the side baffle 500 and the main baffle 400 to cooperate better and further improve the fume extraction effect of the fume collection device 200.

[0059] In this embodiment, the fume collection device 200 is equipped with a main baffle 400, which, together with the side baffles 500, enhances the effect of preventing fume escape. In other embodiments, the main baffle 400 may not be provided.

[0060] The side air inlet 321 is located at one end of the side panel 320 near the main panel 310, so that when the smoke escapes from both sides of the main panel 310, it can be quickly drawn into the side air inlet 321, further preventing the smoke from escaping from the side and further improving the smoke extraction effect of the oil fume collection device 200.

[0061] The fume collection device 200 also includes a fume detection device, a controller, and a drive device. The controller is electrically connected to the fume detection device and the drive device. The fume detection device detects the amount of fume and feeds the fume volume data back to the controller. The controller controls the drive device to move the side baffle 500 based on the received fume volume data to close or partially block the side air inlet 321. Compared to manual adjustment, the fume detection device, controller, and drive device make it easier to adjust the rotation angle of the side baffle 500 and allow for more accurate adjustments for different fume volumes, further improving the effect of preventing fume escape.

[0062] like Figure 4 As shown, in this embodiment, each side plate 320 has two side air inlets 321, and the side air inlets 321 are strip-shaped. In other embodiments, the side air inlet 321 may be one or circular. Those skilled in the art can choose the appropriate number and shape of the side air inlets 321 according to actual needs.
