Side draft smoke machine

Abstract

This invention relates to a side-submersible exhaust fan, which includes a body. From bottom to top, the front of the body is provided with a first plate, a first air inlet screen, a smoke baffle, and a second plate. The body has a smoke collection chamber, which is connected to the external environment of the body through the first air inlet screen. The second plate has a second air inlet screen, and the smoke collection chamber is also connected to the external environment of the body through the second air inlet screen. During operation, the smoke baffle acts as a buffer for the fumes. Some of the fumes are drawn into the smoke collection chamber through the first air inlet screen, while the remaining fumes flow upwards along the baffle and are drawn into the smoke collection chamber through the second air inlet screen. This is particularly beneficial when the amount of fumes emitted in the kitchen is large and the shared exhaust duct is congested, making smoke extraction smoother. This eliminates the need to increase the performance of the blower unit to achieve better smoke extraction, resulting in a low-cost product.

Description

Technical Field

[0001] This invention relates to the field of kitchen appliance technology, and in particular to a side-mounted range hood. Background Technology

[0002] Range hoods have been around in China for nearly 20 years, evolving from the initial top-mounted, slim models to the side-mounted, deep models, and then further to the current situation where top-mounted, self-cleaning models and European-style models are the mainstays. Functionally, they can be categorized into multimedia range hoods, built-in range hoods, wall-mounted and side-draft range hoods (also known as side-draft range hoods), solid wood range hoods, and range hoods with a "7"-shaped body, among others. Traditional side-draft range hoods typically have an air inlet located on the front. When the fan is working, it draws the kitchen fumes into the collection chamber and then exhausts them into the common flue. However, to improve the fume extraction efficiency of side-draft range hoods, some manufacturers increase the performance of the fan, which increases the product cost. Summary of the Invention

[0003] The technical problem solved by this invention is to provide a side-mounted smoke exhaust fan that can effectively improve the smoke exhaust effect while being inexpensive.

[0004] The above-mentioned technical problems are solved by the following technical solutions:

[0005] A side-mounted smoke hood includes: a body, on the front of which a first plate, a first air inlet screen, a smoke baffle, and a second plate are arranged sequentially from bottom to top; the body has a smoke collection chamber, which is connected to the external environment of the body through the first air inlet screen; the second plate has a second air inlet screen, and the smoke collection chamber is also connected to the external environment of the body through the second air inlet screen.

[0006] The side-submersible smoke machine of the present invention has the following beneficial effects compared with the prior art:

[0007] In the aforementioned side-mounted range hood, the baffle plate acts as a buffer for the cooking fumes during operation. Part of the fumes are drawn into the smoke collection chamber through the first air inlet, while the remaining fumes flow upwards along the baffle plate and are drawn into the smoke collection chamber through the second air inlet. This design is particularly effective in kitchens with high levels of cooking fumes and congested communal exhaust ducts, ensuring smoother smoke extraction. This eliminates the need to increase the performance of the blower unit to achieve better smoke extraction, resulting in a low-cost product.

[0008] In one embodiment, the body further includes a back panel; the first plate has an inclination angle of a1 relative to the back panel; the surface of the smoke baffle has an inclination angle of a2 relative to the back panel; and the second plate has an inclination angle of a3 relative to the back panel; wherein a1 and a3 are both less than a2. Thus, the structure formed by the first plate, the smoke baffle, and the second plate is similar to a stepped structure. This allows the smoke baffle to effectively buffer the fumes during operation, facilitating the upward flow of some of the fumes to the second air inlet screen, through which they are then drawn into the smoke collection chamber.

[0009] In one embodiment, a1 is -10° to 10°, a2 is 30° to 75°, and a3 is 10° to 30°.

[0010] In one embodiment, the side-mounted smoke hood further includes a bottom panel, a top panel, and two oppositely arranged side panels; both sides of the bottom panel, both sides of the top panel, both sides of the back panel, both sides of the first plate, both sides of the first air inlet mesh, both sides of the smoke baffle, and both sides of the second plate are respectively connected to the two side panels; the bottom panel is also connected to the bottom of the first plate and the bottom of the back panel; the top panel is also connected to the top of the second plate and the top of the back panel.

[0011] In one embodiment, the first plate, the first air inlet mesh, the smoke baffle, and the two side panels cooperate to form a first recess facing the smoke collection chamber; the second plate has a second recess facing the smoke collection chamber, and the second air inlet mesh is disposed on the bottom wall of the second recess. Thus, the first recess has a better smoke-collecting effect, facilitating the intake of external fumes into the smoke collection chamber through the first air inlet mesh. Furthermore, the second recess has a better smoke-collecting effect, facilitating the intake of external fumes into the smoke collection chamber through the second air inlet mesh.

[0012] In one embodiment, the side-mounted smoke fan further includes a fan cabinet; the fan cabinet is disposed within the smoke collection chamber, and the air inlet side of the fan cabinet is disposed opposite to the second plate.

[0013] In one embodiment, the side-mounted smoke machine further includes a connecting shell disposed on the top panel of the machine body and communicating with the smoke collection chamber; the connecting shell is provided with an air outlet for communicating with a common flue, and a check valve is provided at the air outlet; the air outlet end of the air cabinet extends into the connecting shell.

[0014] In one embodiment, the side-mounted smoke machine further includes an oil cup disposed at the bottom of the body, the oil cup being used to receive oil droplets falling downwards along the body.

[0015] In one embodiment, the bottom end of the second air inlet mesh is provided with an oil passage in the horizontal direction. The oil passage has an upper edge and a lower edge arranged sequentially. The upper edge has a first guide portion protruding towards the inside of the smoke collection chamber, and the lower edge has a second guide portion protruding towards the outside of the smoke collection chamber. The bottom panel of the machine body is provided with a plurality of oil passage holes. In this way, part of the oil generated on the second air inlet mesh can flow directly down along the outer side of the front of the machine body, passing sequentially through the outer surface of the second plate, the outer surface of the smoke baffle, the outer surface of the first air inlet mesh, and the outer surface of the first plate into the oil cup below. Another part, when passing through the oil passage, enters the smoke collection chamber under the guidance of the first guide portion and / or the second guide portion, and flows down along the inner surface of the second plate, the inner surface of the smoke baffle, the inner surface of the first air inlet mesh, and the inner surface of the first plate, falling into the oil cup below through the oil passage holes. This allows the oil to be drawn into the oil cup more effectively, preventing it from dripping onto the stove surface when there is a lot of oil.

[0016] In one embodiment, the first air intake mesh is detachably connected to the side panel of the body; the bottom end of the smoke baffle is positioned above or spaced apart from the top end of the first air intake mesh, and the bottom end of the first air intake mesh is positioned above or spaced apart from the top end of the first plate; the bottom end of the first plate is detachably positioned below the bottom panel of the body. Thus, because the bottom end of the smoke baffle is spaced apart from the top end of the first air intake mesh, i.e., a first gap is provided between the bottom end of the smoke baffle and the top end of the first air intake mesh, the oil flowing outside the smoke baffle can smoothly flow into the smoke collection chamber through this first gap and flow downwards along the inner surface of the first air intake mesh, thereby minimizing the risk of oil dripping onto the cooktop. Similarly, since the bottom of the first air intake mesh is spaced above the top of the first plate, that is, there is a second gap between the bottom of the first air intake mesh and the top of the first plate, the oil stains flowing on the outside of the first air intake mesh can flow smoothly into the smoke collection chamber through the second gap and flow downward along the inner surface of the first plate, which can minimize the risk of oil stains dripping onto the stove surface.

[0017] In one embodiment, the bottom end of the smoke baffle is provided with a first flange, and the first flange is provided with a plurality of first connecting holes; the top end of the first air inlet mesh is provided with a second flange, and the second flange is provided with a plurality of second connecting holes, the plurality of second connecting holes being arranged one-to-one with the plurality of first connecting holes; the bottom end of the first air inlet mesh is provided with a third flange, and the third flange is provided with a plurality of third connecting holes; the top end of the first plate is provided with a fourth flange, and the fourth flange is provided with a plurality of fourth connecting holes, the plurality of fourth connecting holes being arranged one-to-one with the plurality of third connecting holes; the bottom end of the first plate is provided with a fifth flange, the fifth flange abutting against the bottom panel and being detachably connected to the bottom panel.

[0018] In one embodiment, the side-mounted fume hood further includes a door panel movably mounted on the body, the door panel being openable and closable on the second air inlet screen. Thus, when cooking with a high volume of fumes, opening the door panel on the second air inlet screen allows fumes to enter the body through both the first and second air inlet screens; when cooking with a low volume of fumes, closing the door panel closes the second air inlet screen, preventing fumes from entering. The fumes in the kitchen are only drawn into the fume collection chamber through the first air inlet screen. Since the door panel is closed on the second panel, it does not obstruct the cook's view, and simultaneously reduces noise generated by the fan. Attached Figure Description

Detailed Implementation

[0035] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] See Figure 1 , Figure 1 This diagram illustrates the flow of oil along the front of the body 10 during operation of a side-mounted smoke extractor according to an embodiment of the present invention. Figure 2 A cross-sectional view of a side-submersible smoke hood according to an embodiment of the present invention is shown. The side-submersible smoke hood provided in this embodiment includes a body 10. From bottom to top, a first plate 11, a first air inlet screen 12, a smoke baffle 13, and a second plate 14 are sequentially arranged on the front of the body 10. The body 10 has a smoke collection chamber 101, which is connected to the external environment of the body 10 through the first air inlet screen 12. A second air inlet screen 141 is provided on the second plate 14, and the smoke collection chamber 101 is also connected to the external environment of the body 10 through the second air inlet screen 141.

[0037] In the aforementioned side-mounted range hood, the baffle 13 acts as a buffer against cooking fumes during operation. A portion of the fumes is drawn into the smoke collection chamber 101 through the first air inlet 12, while the remaining fumes flow upwards along the baffle 13 and are drawn into the smoke collection chamber 101 through the second air inlet 141. This design is particularly effective in kitchens with high levels of cooking fumes and congested common ventilation ducts, ensuring smoother smoke extraction. This eliminates the need to increase the performance of the blower unit 20 to achieve better smoke extraction, resulting in a low-cost product.

[0038] It should be noted that the external environment of the fuselage 10 refers to the environment in which the fuselage 10 is located, such as a kitchen space.

[0039] Please see Figure 1 and Figure 2 Furthermore, the fuselage 10 also includes a back panel 15. The first plate 11 is tilted at an angle a1 relative to the back panel 15. The surface of the smoke baffle 13 is tilted at an angle a2 relative to the back panel 15. The second plate 14 is tilted at an angle a3 relative to the back panel 15. Both a1 and a3 are less than a2. Thus, the structure formed by the first plate 11, the smoke baffle 13, and the second plate 14 is similar to a stepped structure. This allows the smoke baffle 13 to effectively buffer the fumes during operation, facilitating the upward flow of some of the fumes to the second air inlet 141, where they are then drawn into the smoke collection chamber 101.

[0040] In one embodiment, a1 is -10° to 10°, a2 is 30° to 75°, and a3 is 10° to 30°.

[0041] Please see Figure 1 and Figure 2 Furthermore, specifically, the first air intake screen 12 is flat. Since the first air intake screen 12 is installed on the smoke baffle 13, the tilt angle of the first air intake screen 12 relative to the back panel 15 is the same as a2. a2 is specifically, for example, 50°, 55°, 60°, 65° or 70°, so that the rising fumes generated by the first air intake screen 12 facing the stove surface can be easily drawn into the smoke collection chamber 101.

[0042] Please see Figure 1 and Figure 2 Furthermore, specifically, the first air inlet screen 12 has a plurality of first filter holes 121 on its surface. The second air inlet screen 141 has second filter holes 1411 on its surface. When the side-mounted fume extractor is working, the fumes will be filtered through the filter holes of the first air inlet screen 12 and the second air inlet screen 141 before entering the fume collection chamber 101. Specifically, the shapes of the first filter holes 121 and the second filter holes 1411 can be, for example, elongated holes, square holes, circular holes, elliptical holes, etc., and are not limited here, but can be set according to the actual situation.

[0043] Please see Figure 1 and Figure 2 In one embodiment, the side-mounted smoke hood further includes a bottom panel 16, a top panel 17, and two oppositely arranged side panels 18. The two sides of the bottom panel 16, the two sides of the top panel 17, the two sides of the back panel 15, the two sides of the first plate 11, the two sides of the first air inlet mesh 12, the two sides of the smoke baffle 13, and the two sides of the second plate 14 are respectively connected to the two side panels 18. The bottom panel 16 is also connected to the bottom of the first plate 11 and the bottom of the back panel 15. The top panel 17 is also connected to the top of the second plate 14 and the top of the back panel 15.

[0044] Please see Figure 1 , Figure 2 and Figure 7 , Figure 7This diagram shows a view of the side-mounted smoke hood door panel 50 when it is open, according to an embodiment of the present invention. In one embodiment, the first plate 11, the first air inlet screen 12, the smoke baffle 13, and the two side panels 18 cooperate to form a first recess facing the smoke collection chamber 101. The second plate 14 has a second recess facing the smoke collection chamber 101, and the second air inlet screen 141 is disposed on the bottom wall of the second recess. Thus, the first recess has a better smoke-gathering effect, which is beneficial for drawing external fumes into the smoke collection chamber 101 through the first air inlet screen 12. In addition, the second recess has a better smoke-gathering effect, which is beneficial for drawing external fumes into the smoke collection chamber 101 through the second air inlet screen 141.

[0045] It should be noted that the "second air inlet mesh 141" can be "a part of the second panel 14", that is, the "second air inlet mesh 141" is integrally molded with "other parts of the second panel 14"; or it can be a separate component that can be separated from "other parts of the second panel 14", that is, the "second air inlet mesh 141" can be manufactured independently and then combined with "other parts of the second panel 14" to form a whole. Figure 1 and Figure 7 As shown, in one embodiment, the "second air inlet mesh 141" is integrally molded as part of the "second plate 14".

[0046] Please see Figure 1 and Figure 2 In one embodiment, the side-mounted range hood also includes a fan housing 20. The fan housing 20 is disposed within the smoke collection chamber 101, with its air inlet side 21 facing the second plate 14. Thus, because the air inlet side 21 of the fan housing 20 is facing the second plate 14, the fan housing 20 can generate a large suction force at the second air inlet screen 141, allowing the cooking fumes in the kitchen space to enter the fan housing 20 through the second air inlet screen 141, resulting in a better removal of cooking fumes from the kitchen space.

[0047] Please see Figure 2 , Figure 11 and Figure 12 , Figure 11 This diagram shows a view of the door panel 50 and one of the side panels 18 of a side-mounted smoke hood according to an embodiment of the present invention, after they are hidden. Figure 12This diagram shows another perspective view of the side-mounted range hood with its door panel 50 and one of its side panels 18 concealed, according to an embodiment of the present invention. In one embodiment, the side-mounted range hood further includes a connecting shell 30 disposed on the top panel 17 of the body 10 and communicating with the smoke collection chamber 101. The connecting shell 30 is provided with an air outlet 31, which is used to communicate with a common flue (not shown in the figure), and a check valve 32 is provided at the air outlet 31. The air outlet 22 of the fan hood 20 extends into the connecting shell 30. Thus, when the fan hood 20 is working, it draws the fumes from the kitchen space into the body 10 through the first air inlet screen 12 or the first air inlet screen 12 and the second air inlet screen 141, and sends them out to the common flue through the air outlet 31. When the fan hood 20 stops working, the check valve 32 prevents the fumes in the common flue from flowing back into the body 10 through the air outlet 31, thereby preventing the fumes in the common flue from flowing back into the kitchen space.

[0048] Please see Figure 1 and Figure 2 In one embodiment, the side-mounted smoke machine also includes an oil cup 40 disposed at the bottom of the body 10, the oil cup 40 being used to receive oil droplets falling downwards along the body 10.

[0049] See Figures 2 to 6 , Figure 3 It shows Figure 2 Enlarged structural diagram at point A Figure 4 It shows Figure 2 Enlarged structural diagram at point B Figure 5 It shows Figure 2 Enlarged structural diagram at point C Figure 6 It shows Figure 2An enlarged structural diagram at point D. In one embodiment, the bottom end of the second air inlet 141 is provided with an oil passage 1412 along the lateral direction. The oil passage 1412 has an upper edge and a lower edge arranged sequentially. The upper edge has a first guide portion 1413 protruding towards the inside of the smoke collection chamber 101, and the lower edge has a second guide portion 1414 protruding towards the outside of the smoke collection chamber 101. The bottom panel 16 of the body 10 is provided with a plurality of oil passage holes 161. Specifically, the first guide portion 1413 and the second guide portion 1414 are both formed, for example, by pressing the second air inlet 141. In this way, some of the oil stains generated on the second air intake screen 141 can flow directly down the outer side of the front of the main body 10, passing sequentially over the outer surface of the second plate 14, the outer surface of the smoke baffle 13, the outer surface of the first air intake screen 12, and the outer surface of the first plate 11, into the oil cup 40 below. Another portion, when passing through the oil outlet 1412, enters the smoke collection chamber 101 under the guiding action of the first guide part 1413 and / or the second guide part 1414, and flows down along the inner surface of the second plate 14, the inner surface of the smoke baffle 13, the inner surface of the first air intake screen 12, and the inner surface of the first plate 11, falling into the oil cup 40 below through the oil outlet 161. This effectively guides the oil stains evenly into the oil cup 40, preventing excessive oil stains from dripping onto the stove surface.

[0050] See Figures 2 to 6 In one embodiment, the first air intake screen 12 is detachably connected to the side panel 18 of the body 10. The bottom end of the smoke baffle 13 is positioned above or spaced apart from the top end of the first air intake screen 12, and the bottom end of the first air intake screen 12 is positioned above or spaced apart from the top end of the first plate 11. The bottom end of the first plate 11 is detachably positioned below the bottom panel 16 of the body 10. Thus, since the bottom end of the smoke baffle 13 is spaced apart from the top end of the first air intake screen 12, i.e., a first gap is provided between the bottom end of the smoke baffle 13 and the top end of the first air intake screen 12, the oil flowing outside the smoke baffle 13 can flow smoothly into the smoke collection chamber 101 through the first gap and flow downward along the inner surface of the first air intake screen 12, thereby minimizing the risk of oil dripping onto the stove surface.

[0051] Similarly, since the bottom of the first air intake mesh 12 is spaced above the top of the first plate 11, that is, there is a second gap between the bottom of the first air intake mesh 12 and the top of the first plate 11, the oil stains flowing on the outside of the first air intake mesh 12 can flow smoothly into the smoke collection chamber 101 through the second gap and flow downward along the inner surface of the first plate 11, which can minimize the risk of oil stains dripping onto the stove surface.

[0052] It should be noted that when the bottom end of the smoke baffle 13 is positioned above the top end of the first air inlet mesh 12, meaning there is no first gap for oil flow between the bottom end of the smoke baffle 13 and the top end of the first air inlet mesh 12, the oil flowing on the outside of the smoke baffle 13 still flows downwards along the outside. Similarly, when the bottom end of the first air inlet mesh 12 is positioned above the top end of the first plate 11, meaning there is no second gap for oil flow between the bottom end of the first air inlet mesh 12 and the top end of the first plate 11, the oil flowing on the outside of the first air inlet mesh 12 still flows downwards along the outside.

[0053] See Figure 2 and Figure 4 In one embodiment, the bottom end of the smoke baffle 13 is provided with a first flange 131, and the first flange 131 is provided with a plurality of first connecting holes 1311. The top end of the first air inlet mesh 12 is provided with a second flange 122, and the second flange 122 is provided with a plurality of second connecting holes 1221, and the plurality of second connecting holes 1221 are provided in a one-to-one correspondence with the plurality of first connecting holes 1311.

[0054] See Figure 2 and Figure 5 Furthermore, the bottom end of the first air inlet mesh 12 is provided with a third flange 123, and the third flange 123 is provided with a plurality of third connecting holes 1231. The top end of the first plate 11 is provided with a fourth flange 111, and the fourth flange 111 is provided with a plurality of fourth connecting holes 1111, and the plurality of fourth connecting holes 1111 are provided in a one-to-one correspondence with the plurality of third connecting holes 1231.

[0055] See Figure 2 and Figure 6 Furthermore, a fifth flange 112 is provided at the bottom end of the first plate 11, and the fifth flange 112 abuts against the bottom panel 16 and is detachably connected to the bottom panel 16.

[0056] See Figures 7 to 10 , Figure 8 This diagram shows another perspective view of the side-mounted smoke machine door panel 50 when it is open, according to an embodiment of the present invention. Figure 9 This diagram shows a view of the side-mounted smoke machine's door panel 50 when it is closed, according to an embodiment of the present invention. Figure 10This diagram shows another perspective view of the side-mounted range hood with its door panel 50 closed according to an embodiment of the present invention. In one embodiment, the side-mounted range hood further includes a door panel 50 movably disposed on the body 10, and the door panel 50 is openably disposed on the second air inlet screen 141. Thus, when cooking with a large amount of oil fumes, opening the door panel 50 on the second air inlet screen 141 allows oil fumes to enter the body 10 through both the first air inlet screen 12 and the second air inlet screen 141; when cooking with a small amount of oil fumes, closing the door panel 50 and the second air inlet screen 141 prevents oil fumes from entering the second air inlet screen 141, meaning that oil fumes in the kitchen space are only drawn into the smoke collection chamber 101 through the first air inlet screen 12. Since the door panel 50 is closed on the second panel 14, the door panel 50 does not obstruct the cook's view, and at the same time, the door panel 50 blocks the noise generated by the blower 20, reducing cooking noise.

[0057] Furthermore, the side-mounted range hood also includes a drive mechanism 60, a controller (not shown in the figure), and a sensor (not shown in the figure). The drive mechanism 60 is connected to the door panel 50 and is used to push the door panel 50 to open or close it. In addition, the controller is electrically connected to the drive mechanism 60 and the sensor respectively. The sensor is used to sense the concentration of oil fumes, and the controller is used to control the drive mechanism 60 to operate according to the concentration of oil fumes. Thus, when the sensor senses that the concentration of oil fumes exceeds a preset range, the controller correspondingly controls the drive mechanism 60 to open the door panel 50, thereby ensuring that the oil fumes generated in the kitchen space are completely removed; when the sensor senses that the concentration of oil fumes is less than the preset range, the controller correspondingly controls the drive mechanism 60 to close the door panel 50, that is, the oil fumes generated in the kitchen space are simply drawn into the smoke collection chamber 101 through the first air inlet mesh 12 located below the second plate 14.

[0058] In this embodiment, the sensor is, for example, a smoke sensor, specifically an infrared smoke sensor. Of course, it can also be other types of smoke sensors, which are not limited here and can be set according to actual needs.

[0059] Furthermore, the controller can also adjust the extension length and / or working time of the drive mechanism 60 according to the concentration of oil fumes, thereby adjusting the opening angle and duration of the door panel 50 and adjusting its position in real time to achieve better oil fume extraction. When the detected oil fume concentration increases, the drive mechanism 60 drives the door panel 50 to open at a larger angle; conversely, when the detected oil fume concentration decreases, the drive mechanism 60 drives the door panel 50 to open at a smaller angle.

[0060] As an example, the detected oil fume concentration is divided into five levels from lowest to highest: Level 1, Level 2, Level 3, Level 4, and Level 5. Level 1 has an oil fume concentration of, for example, 0. Level 2 has an oil fume concentration from 0 to a first set value, Level 2 has an oil fume concentration from the first set value to the second set value, Level 3 has an oil fume concentration from the second set value to the third set value, Level 4 has an oil fume concentration from the third set value to the fourth set value, and Level 5 has an oil fume concentration above the fourth set value, with Level 5 having the highest oil fume concentration. When the detected oil fume concentration is at Level 1, the controller stops the air handling unit 20 from operating and completely closes the door panel 50. When the detected oil fume concentration is at Level 2, the controller starts the air handling unit 20 from operating and completely closes the second air inlet screen 141. At this time, the oil fume only enters the smoke collection chamber 101 through the first air inlet screen 12. When the detected fume concentration is at the third level, the controller controls the air handling unit 20 to operate, and the drive mechanism 60 drives the door panel 50 to open at the first opening angle. At this time, the fume enters the fume collection chamber 101 through the first air inlet screen 12 and the second air inlet screen 141. When the detected fume concentration is at the fourth level, the controller controls the air handling unit 20 to operate, and the drive mechanism 60 drives the door panel 50 to open at the second opening angle. At this time, the fume enters the fume collection chamber 101 through the first air inlet screen 12 and the second air inlet screen 141, and the second opening angle is greater than the first opening angle. When the detected fume concentration is at the fifth level, the controller controls the air handling unit 20 to operate, and the drive mechanism 60 drives the door panel 50 to open the third air inlet at the third opening angle. At this time, the fume enters the fume collection chamber 101 through the first air inlet screen 12 and the second air inlet screen 141, and the third opening angle is greater than the second opening angle.

[0061] Please see Figure 7 and Figure 9 In one embodiment, the main body 10 is provided with control buttons 102 electrically connected to the controller. Thus, control signals are sent to the controller via the control buttons 102, thereby controlling the drive mechanism 60 to adjust the opening angle and duration of the door panel 50, allowing for manual adjustment according to individual needs. Furthermore, the control buttons 102 can also be used to manually turn the machine on and off, turn the lights on or off, adjust the operating speed of the air handling unit 20, and perform other operations. Specifically, the door panel 50 is a glass control panel, and the control buttons 102 are located on the glass control panel.

[0062] It should be noted that the controller can be integrated into the glass control panel or placed in other parts of the body 10 and electrically connected to the glass control panel via wires. The specific configuration can be determined according to the actual situation and is not limited here.

[0063] Furthermore, the controller is electrically connected to the fan unit 20. On the one hand, the operating level of the fan unit 20 can be adjusted manually by operating the control button 102; on the other hand, the operating level of the fan unit 20 can also be adjusted by the controller according to the oil fume concentration detected by the sensor.

[0064] See Figures 7 to 10 Furthermore, the second plate 14 is provided with two movable holes 142, which are respectively located on opposite sides of the second plate 14. The side-mounted smoke machine also includes two baffles 70. The two baffles 70 are movably disposed in the two movable holes 142 in a one-to-one correspondence. The top of the door panel 50 is rotatably connected to the body 10, and the door panel 50 is connected to the two baffles 70 respectively. The drive mechanism 60 is installed on the cavity wall of the smoke collection chamber 101, and the drive mechanism 60 is connected to one of the baffles 70. The drive mechanism 60 is used to drive the baffle 70 to move, so as to open or close the door panel 50. When the machine is turned on, the drive mechanism 60 drives the baffle plate 70 to move, and the baffle plate 70 drives the door panel 50 to rotate, so that the door panel 50 opens. In this way, the oil fumes in the kitchen space can be drawn into the smoke collection chamber 101 through the second air inlet net 141 and discharged to the public flue. When the machine is turned off, the drive mechanism 60 drives the baffle plate 70 to move, and the baffle plate 70 drives the door panel 50 to rotate, so that the door panel 50 closes and seals the second air inlet net 141. Thus, on the one hand, the drive structure and method of the side-submersible smoke hood are simpler and more reliable than the traditional four-bar linkage mechanism, and are also easier to assemble and clean. On the other hand, when the door panel 50 is opened, the two baffles 70 connected to the door panel 50 move out through the movable hole 142 to the outside of the smoke collection chamber 101. The two baffles 70 can prevent the oil fumes from escaping to the side and achieve a better smoke collection effect, thereby improving the suction effect of the side-submersible smoke hood. When the door panel 50 is closed, the door panel 50 is attached to the second plate 14, and the two baffles 70 move into the smoke collection chamber 101, thereby avoiding obstruction of vision.

[0065] See Figures 7 to 10 Furthermore, the drive mechanism 60 can be an electric push rod, a motor lead screw, a cylinder, a hydraulic cylinder, a gear drive structure, or a pulley drive structure. The drive mechanism 60 primarily provides power to rotate the door panel 50; its specific configuration is not limited here and can be designed according to actual needs. In this embodiment, an electric push rod is specifically selected. The electric push rod drives the windshield 70 by changing its own length; its structure is relatively simple and reliable, and it occupies less space.

[0066] See Figures 7 to 10 Furthermore, one end of the drive mechanism 60 is rotatably connected to the wall of the smoke collection chamber 101, and the other end of the drive mechanism 60 is rotatably connected to the wind deflector 70. In this way, during the process of the drive mechanism 60 driving the wind deflector 70, the door panel 50 can be smoothly rotated around the body 10 to open or close.

[0067] Please see Figure 11 and Figure 12 In one embodiment, a support 80 is provided on the cavity wall of the smoke collection chamber 101, and the end of the drive mechanism 60 is rotatably disposed on the support 80.

[0068] Please see Figure 11 and Figure 12 Furthermore, the door panel 50 is provided with a first rotating hole (not shown), and one end of the drive mechanism 60 is provided with a second rotating hole (not shown). The door panel 50 is rotatably connected to one end of the drive mechanism 60 via a first rotating pin (not shown) inserted into the first rotating hole and the second rotating hole. The first rotating pin is provided with a first limiting hole (not shown), and a first locking pin (not shown) is inserted into the first limiting hole. In this way, after the first rotating pin is inserted into the first rotating hole and the second rotating hole connects the door panel 50 and one end of the drive mechanism 60, the first locking pin is inserted into the first limiting hole to prevent the first rotating pin from loosening, and the end of the drive mechanism 60 can be quickly rotatably connected to the door panel 50.

[0069] Similarly, the support 80 is provided with a third rotating hole (not shown), and the other end of the drive mechanism 60 is provided with a fourth rotating hole (not shown). The support 80 is rotatably connected to the other end of the drive mechanism 60 by inserting a second rotating pin (not shown) into the third and fourth rotating holes. The second rotating pin is provided with a second limiting hole (not shown), and a second locking pin is inserted into the second limiting hole. In this way, after the second rotating pin is inserted into the third and fourth rotating holes to connect the support 80 and the other end of the drive mechanism 60, inserting the second locking pin into the second limiting hole prevents the second rotating pin from loosening, and can quickly rotatably connect the end of the drive mechanism 60 and the support 80 together.

[0070] Please see Figure 11 and Figure 12 Furthermore, the top of the door panel 50 is connected to the top panel 17 via at least one hinge 90. Specifically, the top of the door panel 50 is rotatably connected to the top panel 17 via two hinges 90, thus ensuring a more stable rotation of the door panel 50. In addition, the body 10 also includes a back panel 15 connected to the top panel 17. The support 80 is specifically disposed on the back panel 15.

[0071] See Figure 7In one embodiment, at least one buffer block 143 is provided on the second plate 14. When the door panel 50 is closed onto the second air inlet grille 141, it abuts against the buffer block 143. It should be noted that the size, shape, specific material, and specific number of buffer blocks 143 are not limited, as long as they can abut against the door panel 50 when it is closed onto the second plate 14, providing a buffering effect and preventing damage to the door panel 50 due to force. They can be selected according to the actual situation. In this embodiment, for example, there are two buffer blocks 143, which are respectively arranged on both sides of the bottom end of the second plate 14.

[0072] It should be noted that the "smoke baffle 13" can be "a part of the second plate 14", that is, the "smoke baffle 13" is integrally formed with "other parts of the second plate 14"; or it can be a separate component that can be separated from "other parts of the second plate 14", that is, the "smoke baffle 13" can be manufactured independently and then combined with "other parts of the second plate 14" to form a whole. Figure 7 and Figure 8 As shown, in one embodiment, the "smoke baffle 13" is integrally molded as part of the "second plate 14".

[0073] It should also be noted that the "bottom panel 16" can be a "part of the back panel 15", meaning the "bottom panel 16" is integrally molded with the "other parts of the back panel 15"; or it can be a separate component that can be separated from the "other parts of the back panel 15", meaning the "bottom panel 16" can be manufactured independently and then combined with the "other parts of the back panel 15" to form a whole. For example... Figure 8 and Figure 12 As shown, in one embodiment, the "bottom panel 16" is integrally molded as part of the "back panel 15".

[0074] It should be noted that the front of the unit 10 refers to the side of the range hood facing the user after it is installed in the kitchen. The back of the unit 10 refers to the side of the range hood facing the wall after it is installed in the kitchen, which is the side opposite to the front of the unit 10. The top of the unit 10 refers to the side of the range hood that is away from the ground after it is installed in the kitchen. The sides of the unit 10 refer to the sides of the unit 10 located on either the front or the back of the unit 10.

[0075] It should be noted that when describing a component being connected to another component, or a component being mounted on another component, it can be understood that the connection between the two components can specifically involve using mounting components such as bolts, screws, pins, and rivets, or using snap-fit, welding, or integral molding methods for fixation.
