Description

Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, and in particular to a linkage technology between an upper air inlet and a lower air inlet of a submersible smoke extractor. Background Art

[0002] Currently, the three most common range hoods on the market are top-draft, side-draft, and submersible. Top-draft range hoods typically have their hoods flush with the cabinet floor, requiring a high installation position. This results in a long distance between the air inlet and the stovetop, resulting in poor extraction efficiency and the risk of hitting your head while cooking. To improve extraction efficiency, the motor power must be increased, which comes with drawbacks such as increased noise and higher costs.

[0003] Side-suction range hoods place the air inlet closer to the stovetop, improving extraction efficiency. However, their hood system is larger, resulting in a smaller overall smoke collection chamber. When the hood system is positioned above or mid-upper, part of the smoke hood is located above the cabinet surface. Furthermore, the side-suction range hood is at an angle to the stovetop, resulting in poor smoke collection and allowing fume to escape.

[0004] The submersible range hood achieves the downward shift of the negative pressure area. For example, a lifting range hood with the authorization publication number CN206207511U solves the problem of the air inlet being too far away from the stove by lowering the air inlet. However, the bottom of the smoke collecting chamber is curved or inclined. When the oil smoke rises, it will directly contact the bottom of the smoke collecting chamber. There is a problem of low negative pressure at the air inlet and no smoke baffle, which causes serious oil smoke escape. In addition, the air inlet is close to the stove, and installing a smoke shield at the air inlet will cause the pot to hit the pot. Therefore, patent number ZL201820985116.9 is a lifting range hood, which discloses a method of providing an air inlet below the smoke collecting chamber and adding an air inlet and a smoke shield on the upper part of the smoke collecting chamber. However, the use of two air inlets and smoke shields will increase the power of the motor and increase the cost; in addition, since an air inlet is also provided on the upper part of the stove, the plane where the upper air inlet of the range hood is located occupies a large space, which is prone to bumping during cooking. Summary of the Invention

[0005] The present invention aims to solve at least one of the problems existing in the existing related technologies to a certain extent. To this end, the present invention proposes a submersible smoke extraction fan with an upper air inlet and a lower air inlet linked together, which can form a larger smoke-collecting area to prevent oil smoke from escaping. At the same time, through the linkage between the upper and lower air inlets, the manufacturing cost is reduced and the controllability of each moving part is improved, which can effectively solve the problem of poor smoking effect of side-suction range hoods due to the rear placement of the negative pressure zone.

[0031] The following examples illustrate the present invention, but the present invention is not limited to these examples. Modifications to the specific embodiments of the present invention or equivalent replacements of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed in the present invention.

[0032] Example 1

[0033] like Figure 1-5As shown, a submersible smoking machine with an upper air inlet and a lower air inlet linked in this embodiment includes a smoke hood 1, a panel assembly 2, a driving mechanism 3, a fan assembly 81, a smoke exhaust device 82 and an oil cup 9. The smoke hood 1 has an upper air inlet 11 and a lower air inlet 10. The panel assembly 2 is movably arranged at the upper air inlet 11 for opening or closing the upper air inlet 11. The driving mechanism 3 is arranged on the smoke hood 1 and connected to the panel assembly 2 for driving the panel assembly 2 to perform forward and backward telescopic movement. The fan assembly 81 is arranged inside the smoke hood 1 with its air inlet end facing the upper air inlet 11, and is used to reduce the distance between the fan assembly 81 and the upper air inlet 11, thereby increasing the negative pressure at the upper air inlet 11 to improve the smoking effect. The smoke exhaust device 82 is arranged at the top middle position of the smoke hood 1 and is connected to the fan assembly 81 for discharging smoke into the atmosphere. The oil cup 9 is detachably mounted at the bottom of the smoke hood 1 for containing oil droplets. It also includes an oil net assembly 4 and a smoke guide plate assembly 7. The oil net assembly 4 is movably arranged between the panel assembly 2 and the smoke hood 1 and moves synchronously with the movement of the panel assembly 2. The smoke guide plate assembly 7 is movably arranged at the lower air inlet 10 and is movably connected to the oil net assembly 4 for opening or closing the lower air inlet 10, and the smoke guide plate assembly 7 is transmission-connected to the panel assembly 2 through the oil net assembly 4.

[0034] When the driving mechanism 3 drives the panel assembly 2 to extend forward to open the upper air inlet 11, the panel assembly 2 can synchronously drive the oil screen assembly 4 to flip synchronously, and the movement of the oil screen assembly 4 can drive the smoke guide plate assembly 7 to rotate or translate to open the lower air inlet 10. Figure 4-5 When the panel assembly 2 moves to the maximum open position, the oil net assembly 4 and the panel assembly 2 enclose a negative pressure zone, which is conducive to guiding the oil smoke into the interior of the smoke collection hood 1 and improving the smoking effect. At the same time, the smoke guide plate assembly 7 opens the lower air inlet 10, increasing the unit smoke intake area and further enhancing the smoking effect. Smoke is drawn through the upper and lower air inlets (10, 11), effectively solving the problem of poor smoking effect caused by the rear position of the negative pressure zone in the side-suction range hood with the oil net raised and lowered. When the driving mechanism 3 drives the panel assembly 2 to move backward to close the upper air inlet 11, the panel assembly 2 can simultaneously drive the oil net assembly 4 to move back into the interior of the smoke collection hood 1. The movement of the oil net assembly 4 drives the smoke guide plate assembly 7 to move to close the lower air inlet 10. When the driving mechanism 3 stops working, the panel assembly 2 closes the upper air inlet 11 and the smoke guide plate assembly 7 closes the lower air inlet 10, preventing smoke from entering the interior of the submersible range hood and improving the overall appearance of the submersible range hood.

[0035] The present embodiment provides a submersible range hood, wherein the oil screen assembly 4 is designed to move synchronously with the movement of the panel assembly 2, and the movement of the oil screen assembly 4 can drive the movement of the smoke guide plate assembly 7. When the submersible range hood is in operation, the oil screen assembly 4 and the panel assembly 2 can enclose a negative pressure zone, and the upper and lower air inlets (10, 11) are opened simultaneously to increase the unit smoke intake area, further enhancing the smoking effect, thereby effectively solving the problem of poor smoking effect caused by the rearward placement of the negative pressure zone in side-suction range hoods with a lifting oil screen. In addition, only one drive mechanism 3 is required to control the movement of each moving component, namely, the movement of the control panel assembly, the oil screen assembly 4, and the smoke guide plate assembly 7. This helps to reduce the number of drive mechanisms 3 and the space occupied, improve the movement synchronization and controllability of each moving component, and reduce manufacturing costs.

[0036] like Figure 1-2 As shown, further, the lower air inlet 10 and the upper air inlet 11 are respectively provided at the lower and upper ends of the front face of the smoke hood 1, so that the installation position of the panel assembly 2 is relatively high, thereby preventing the user's head from hitting the panel assembly 2 during the cooking process. Preferably, the lower end of the front face of the smoke hood 1 is a slope or arc surface that tilts downward and backward, and the lower air inlet 10 is provided on the slope or arc surface. This can form a side suction effect. When the oil smoke flows upward, part of the oil smoke is sucked into the interior of the smoke hood 1 from the lower air inlet 10, and part of the oil smoke that escapes upward is sucked into the interior of the smoke hood 1 from the upper air inlet 11. By drawing smoke from both the upper and lower parts simultaneously, the smoking effect can be further improved. In this embodiment, the lower end of the front face of the smoke hood 1 is a slope.

[0037] Specifically, an oil net bracket 12 is provided inside the smoke hood 1. The oil net bracket 12 is fixedly connected to the inclined surface of the smoke hood 1 and is located between the upper air inlet 11 and the lower air inlet 10. It is used to be rotatably connected to the oil net assembly 4, and at the same time prevent the oil net assembly 4 from interfering with the fan assembly 81 when it is retracted into the smoke hood 1.

[0038] like Figure 2 and Figure 5 As shown, the panel assembly 2 further includes a panel 21 and two fixing bases 22. The two fixing bases 22 are fixedly mounted on the left and right sides of the back of the panel 21, and each fixing base 22 is connected to the oil screen assembly 4. Preferably, the panel 21 is a glass panel to enhance the overall aesthetics of the product and facilitate user cleaning. More preferably, to ensure that the panel 21 is fully aligned with the upper air inlet 11 of the smoke collection chamber 1, sponge strips can be added around the panel 21.

[0039] Preferably, the fixing base 22 is a rectangular plate. This allows for a large bonding area when the fixing base 22 is adhesively attached to the back of the panel 21, thereby enhancing the connection strength. The side of the fixing base 22 facing away from the panel 21 is provided with a lower bracket 221 and a middle bracket 223 spaced apart and arranged side by side. The lower bracket 221 is located in the lower half of the width of the panel 21 and is rotatably connected to the oil screen assembly 4. The middle bracket 223 is located in the middle of the width of the panel 21 and is connected to the drive mechanism 3.

[0040] like Figure 2 and Figure 4-6 As shown, further, there are two oil net brackets 12, and the two oil net brackets 12 are respectively fixedly connected to the left and right sides of the inclined surface of the smoke hood 1 and close to the lower edge of the upper air inlet 11. The oil net assembly 4 includes an oil net 41 and two first sliders 42. The oil net 41 is rotatably arranged between the lower half of the panel assembly 2 and the smoke hood 1. The two first sliders 42 are respectively arranged on the left and right sides of the oil net 41, and one end of each first slider 42 is hingedly connected to the corresponding lower bracket 221, and the other end is slidably connected to the corresponding oil net bracket 12. Therefore, through the cooperation of the two first sliders 42, the two lower brackets 221 and the two oil net brackets 12, the oil net 41 can be synchronously flipped open or reset with the forward and backward telescopic movement of the panel assembly 2, and the flipping movement of the oil net 41 is ensured to be more stable and reliable.

[0041] Specifically, each first slider 42 has a first slot 421 disposed along its length at the end away from the panel assembly 2. The end of each first slider 42 protrudes from the bottom surface of the oil screen 41, facilitating a sliding connection between the first slot 421 and the oil screen bracket 12. An oil screen positioning portion 121 is provided at the upper end of each oil screen bracket 12. This positioning portion 121 is movably inserted into the first slot 421. Thus, the first slot 421 engages with the positioning portion 121, achieving a sliding connection between the first slider 42 and the oil screen bracket 12.

[0042] Preferably, the oil screen 41 and the two first sliders 42 of this embodiment are independent of each other. The two first sliders 42 are fixed to the left and right side walls of the oil screen 41 by welding or bonding, facilitating the processing and forming of the oil screen 41 and the first sliders 42. In other embodiments, the two first sliders 42 can also be designed to be integrally formed with the oil screen 41, so that the two first sliders 42 respectively constitute the left and right side walls of the oil screen 41. This can save manufacturing materials for the oil screen 41, simplify the assembly process of the oil screen assembly 4, improve production efficiency, and eliminate interference between the side walls of the oil screen 41 and the first chute 421.

[0043] like Figure 2 and Figure 4-5As shown, further, the smoke guide plate assembly 7 includes a smoke guide plate 71, which is rotatably or translationally arranged at the lower air inlet 10 and is slidably connected with the first slider 42. Thus, the smoke guide plate 71 is transmission-connected to the panel assembly 2 via the first slider 42, so that the smoke guide plate 71 can achieve synchronous rotation or translational movement with the rotation of the oil screen assembly 4, which is beneficial to improving the movement synchronization and controllability of each moving part and reducing manufacturing costs. Preferably, the shape of the smoke guide plate 71 is the same as that of the lower air inlet 10, and when the smoke guide plate 71 closes the lower air inlet 10, the smoke guide plate 71 is flush with the lower end of the front face of the smoke hood 1 to form a hidden lower air inlet 10, thereby improving the aesthetics of the product.

[0044] like Figure 6-7 As shown, in this embodiment, the edge of the smoke guide plate 71 is provided with a folded edge 710 facing the interior of the smoke hood 1. Each folded edge 710 constitutes a side wall of the smoke guide plate 71. The folded edges 710 located on the left and right sides of the smoke guide plate 71 (i.e., the left and right side walls of the smoke guide plate 71) are respectively provided with a guide groove 711 on the side close to the oil mesh assembly 4. Correspondingly, the end of the first slider 42 close to the smoke guide plate 71 is provided with a smoke guide plate positioning portion 422, which cooperates with the guide groove 711 for sliding connection. Thus, by the smoke guide plate positioning portion 422 fixed to the first slider 42 and cooperating with the guide groove 711, the oil mesh assembly 4 and the smoke guide plate assembly 7 are reliably and movably connected together, thereby achieving transmission connection between the smoke guide plate assembly 7 and the panel assembly 2 through the oil mesh assembly 4.

[0045] like Figure 8 As shown, in other embodiments, the smoke guide plate 71 is a rectangular plate, and a third slider 74 is fixedly connected to the left and right sides of the side of the smoke guide plate 71 facing the interior of the smoke hood 1, respectively. The third slider 74 is "L"-shaped, and has a mounting surface 741 and a folded edge 710. The mounting surface 741 is fixed to the back of the smoke guide plate 71 by bonding or other fixing methods, and the folded edge 710 is respectively provided with a guide groove 711 and a connecting hole 713.

[0046] like Figure 4-6 As shown, specifically, the smoke guide plate assembly 7 also includes two smoke guide plate brackets 72, which are respectively arranged in the smoke collecting hood 1 and fixedly connected to the left and right sides of the lower edge of the lower air inlet 10, and the folded edges 710 on the left and right sides of the smoke guide plate 71 (that is, the left and right side walls of the smoke guide plate 71) are provided with connecting holes 713 close to the smoke guide plate brackets 72, and the connecting holes 713 are pivotally connected to the smoke guide plate brackets 72 through a pin shaft, so that the smoke guide plate 71 can be rotatably set at the lower air inlet 10.

[0047] like Figure 2 and Figure 5As shown, the drive mechanism 3 further includes a driver assembly 31 and a connecting rod assembly 32. The driver assembly 31 is disposed within the smoke hood 1. One end of the connecting rod assembly 32 is connected to the output end of the driver assembly 31, and the other end is connected to the middle bracket 223 of the panel assembly 2 via the slide rail assembly 6. Thus, by controlling the forward and reverse rotation of the driver 311, the rotation of the connecting rod assembly 32 is controlled, and the movement of the connecting rod assembly 32 can drive the panel assembly 2 to perform forward and backward telescopic movement via the slide rail assembly 6.

[0048] Specifically, the driver assembly 31 includes a driver 311 electrically connected to the submersible smoking machine controller, and a housing 312. A through-hole 3121 is defined in the sidewall of the housing 312, through which the output end of the driver 311 passes. The driver 311 is disposed within the housing 312, and its output end extends out of the housing 312 after passing through the through-hole 3121. The end of the driver 311 located outside the housing 312 is connected to the connecting rod assembly 32 to prevent oil from accumulating on the surface of the driver 311 and affecting its performance. Preferably, two stoppers 3122 are defined in the sidewall of the housing 312, surrounding the through-hole 3121. The two stoppers 3122 are located on either side of the end of the connecting rod assembly 32 near the driver 311, respectively, to limit the rotation angle of the connecting rod assembly 32. Thus, the two stoppers 3122 limit the forward and backward travel of the panel assembly 2.

[0049] Specifically, the connecting rod assembly 32 includes an active rod 321 and a driven rod 322. The active rod 321 is arranged between the two limiting parts 3122 and one end of the active rod 321 is fixedly connected to the output end of the driver 311 located outside the box body 312, and the other end is pivotally connected to the driven rod 322. The end of the driven rod 322 away from the active rod 321 is connected to the middle bracket 223 of the panel assembly 2 through the slide rail assembly 6.

[0050] like Figure 2 and Figure 5 As shown, further, there are two slide rail assemblies 6, which are respectively arranged on the left and right sides of the interior of the smoke hood 1. The middle brackets 223 on the two fixing seats 22 are respectively connected to the ends of the two slide rail assemblies 6 close to the panel 21, thereby achieving the front-to-back telescopic movement of the panel 21 at the upper air inlet 11 of the smoke hood 1 through the cooperation of the two slide rail assemblies 6 and the two middle brackets 223, while ensuring that the front-to-back telescopic movement of the panel 21 is more stable. The driven rod 322 is connected to one of the slide rail assemblies 6, so that only one driving mechanism 3 is required to control the movement of the slide rail assembly 6 connected to the driven rod 322, thereby achieving the front-to-back telescopic movement of the control panel assembly 2, the flipping of the oil screen assembly 4 and the flipping movement of the smoke guide plate assembly 7, which is conducive to reducing manufacturing costs.

[0051] like Figure 9As shown, specifically, each slide rail assembly 6 includes a first slide rail 61 and a second slide rail 62. The first slide rail 61 is fixedly installed in the smoke hood 1. The second slide rail 62 is slidably connected to the first slide rail 61 and its end close to the panel 21 is fixedly connected to the middle bracket 223 located on the back of the panel 21. At least one second slide rail 62 is connected to the driven rod 322 of the connecting rod assembly 32. In this embodiment, the second slide rail 62 on the left is fixedly connected to a sliding block 621 at the end away from the panel 21. The sliding block 621 is hinged with the end of the driven rod 322 away from the active rod 321. In this way, by adding the sliding block 621, the driven rod 322 is connected to the second slide rail 62 on the left, so that the driven rod 322 drives the second slide rail 62 to reciprocate through the sliding block 621, thereby causing the panel assembly 2 to telescope forward and backward.

[0052] More specifically, each slide rail assembly 6 also includes a slide rail fixing bracket 63, which is detachably mounted on the inner wall of the smoke hood 1 by screws. The first slide rail 61 is fixedly mounted on the top surface of the slide rail fixing bracket 63 and is slidably connected with the second slide rail 62. In this way, the first slide rail 61 is stably and reliably mounted inside the smoke hood 1 through the slide rail fixing bracket 63.

[0053] like Figure 2 and Figure 4-5 As shown, the smoke shield assembly 5 is further included. The smoke shield assembly 5 is movably arranged between the upper half of the panel assembly 2 and the smoke collection hood 1, and the smoke shield assembly 5 can move synchronously with the movement of the smoke shield assembly 5. Therefore, when the submersible smoke extractor is in operation, the smoke shield assembly 5 and the panel assembly 2 can enclose a smoke trapping area to prevent the smoke from escaping upward, thereby further enhancing the smoke trapping effect.

[0054] Specifically, two smoke damper brackets 13 are provided on the inner side of the top of the smoke hood 1, near the upper edge of the upper air inlet 11. The smoke damper assembly 5 includes a smoke damper 51 and two second sliders 52. The smoke damper 51 is movably arranged between the upper half of the panel assembly 2 and the smoke hood 1. The two second sliders 52 are respectively arranged on the left and right sides of the smoke damper 51, and one end of each second slider 52 is hingedly connected to the corresponding fixing seat 22, and the other end is slidably connected to the corresponding smoke damper bracket 13. Thus, through the cooperation of the two second sliders 52, the two fixing seats 22 and the two smoke damper brackets 13, the smoke damper 51 can be flipped open or reset as the panel assembly 2 moves forward and backward, and the flipping movement of the smoke damper 51 is ensured to be more stable and reliable. In addition, by arranging the two smoke damper brackets 13 on the upper edge of the upper air inlet 11, the smoke damper assembly 5 can be effectively prevented from interfering with the fan assembly 81 when it is retracted into the smoke hood 1.

[0055] Specifically, each second slider 52 has a second slot 521 disposed along its length at one end away from the panel assembly 2. The lower end of each smoke deflector bracket 13 is slidably engaged with the second slot 521 via a pin, thereby slidably connecting the second slider 52 to the smoke deflector bracket 13. Each fixing base 22 is provided with an upper bracket 222 positioned above the middle bracket 223. This upper bracket 222 is hingedly connected to the second slider 52 via a pin, thereby hingedly connecting the second slider 52 to the panel assembly 2.

[0056] Preferably, the smoke deflector 51 and the two second sliders 52 of this embodiment are independent of each other, and the two second sliders 52 are fixed to the left and right side walls of the smoke deflector 51 by welding or bonding. In other embodiments, the two second sliders 52 can also be designed to be integrally formed with the smoke deflector 51, and the two second sliders 52 respectively constitute the left and right side walls of the smoke deflector 51. This can save manufacturing materials for the smoke deflector assembly 5, simplify the assembly process, and eliminate interference between the side walls of the smoke deflector 51 and the second slide groove 521.

[0057] like Figure 1-3 As shown, in this embodiment, the maximum dimension of the submersible smoking machine in the front-to-back direction is less than 250 mm, and the maximum dimension in the up-down direction is 340-400 mm. The maximum dimension of the smoke exhaust device 82 in the front-to-back direction is less than 250 mm, and the maximum dimension in the left-to-right direction is less than 400 mm, and the maximum dimension of the smoke exhaust device 82 in the left-to-right direction is smaller than the maximum dimension of the entire submersible smoking machine in the left-to-right direction. In addition, the maximum dimension of the smoke exhaust device 82 in the up-to-down direction is less than 120 mm, which ensures that the smoke hood 1 has a sufficient height for installing the fan assembly 81. The maximum dimension of the fan assembly 81 in the front-to-back direction is less than 150 mm, which makes it possible to accommodate the fan assembly 81 inside the smoke hood 1 to ensure air intake and smoking effects. It can be seen that compared with the existing range hoods with a length of about 430 mm in the left-right direction and a width of about 350 mm in the front-to-back direction, the submersible range hood of this embodiment has a smaller overall size, reduces the occupied space, is more suitable for matching with different types of cabinets, and improves the assembly adaptability of the submersible range hood; in addition, the overall size of the smoke hood 1 is small, and the internal structure of the smoke hood 1 is more compact, which is conducive to reducing manufacturing costs.

[0058] like Figure 10 As shown, when the submersible smoke extractor is installed, the smoke exhaust device 82 of the submersible smoke extractor is embedded in the interior of the cabinet, and the top surface of the smoke hood 1 fits with the bottom surface of the cabinet, which has a better fit with the cabinet and a more beautiful overall appearance. It is especially suitable for installation on old-style cabinets. At the same time, after the submersible smoke extractor is installed in the cabinet, it can avoid the user's head hitting the cabinet during use, thereby improving the user experience.

[0059] The following combination Figure 1 and Figure 3-5To illustrate the working principle of the present embodiment of the submersible smoking machine:

[0060] like Figure 1 and Figure 4-5 As shown, the submersible smoking hood is turned on, and the submersible smoking hood controller controls the driver 311 to rotate clockwise, driving the active rod 321 to rotate clockwise, and the rotation of the active rod 321 drives the driven rod 322 to move, and the driven rod 322 pushes the second slide rail 62 to extend forward through the sliding block 621, and when the second slide rail 62 extends forward, it simultaneously pushes the panel assembly 2 to move forward to open the upper air inlet 11. In the process of the panel assembly 2 moving forward, the oil net assembly 4 is synchronously driven to flip clockwise through the lower bracket 221 to open the oil net assembly 4. The movement of the oil net assembly 4 can drive the smoke guide plate assembly 7 to flip toward the inside of the smoke hood 1 to open the lower air inlet 10, and at the same time, the smoke baffle assembly 5 is synchronously driven to flip counterclockwise through the upper bracket 222 to open the smoke baffle assembly 5. When the active rod 321 abuts against the limiting portion 312 close to the panel assembly 2, the driver 311 stops working. At this time, the panel assembly 2 is in the maximum open position, the oil net assembly 4 and the panel assembly 2 form a negative pressure area, and introduce the oil smoke into the smoke hood 1 through the upper air inlet 11, thereby improving the smoking effect; the smoke baffle assembly 5 and the panel assembly 2 form a smoke gathering area to prevent the oil smoke from escaping upward; the smoke guide plate assembly 7 is in the maximum open position, and the oil smoke can be introduced into the smoke hood 1 through the lower air inlet 10, thereby increasing the unit smoke collection area and further enhancing the smoking effect, thereby effectively solving the problem of poor smoking effect of the side-suction range hood with oil net lifting due to the rear position of the negative pressure area.

[0061] like Figure 3 As shown, when the submersible smoking machine is turned off, the control driver 311 rotates counterclockwise, and the active rod 321 drives the driven rod 322 to move. The driven rod 322 pulls the second slide rail 62 to retract backward through the sliding block 621. When the second slide rail 62 retracts backward, it simultaneously pulls the panel assembly 2 to close the upper air inlet 11. During the process of the panel assembly 2 retracting backward, the lower bracket 221 drives the oil net assembly 4 to reset synchronously so that the oil net assembly 4 is retracted into the smoke hood 1. The movement of the oil net assembly 4 can drive the smoke guide plate assembly 7 toward the lower air inlet 10. Rotate to close the lower air inlet 10, and at the same time drive the smoke shield assembly 5 to reset synchronously through the upper bracket 222 to retract the smoke shield assembly 5 into the smoke hood 1; when the active rod 321 abuts against the limit portion 312 away from the panel assembly 2, the driver 311 stops working, and at this time the panel assembly 2 closes the upper air inlet 11, and the smoke guide plate assembly 7 closes the lower air inlet 10 to prevent smoke and dust from entering the smoke hood 1 through the upper and lower air inlets (10, 11), and the oil net assembly 4 and the smoke shield assembly 5 retract into the smoke hood 1 to ensure the beautiful appearance of the submersible smoke extractor.

[0062] Example 2

[0063] like Figure 11 As shown, this embodiment differs from Example 1 in that the structure of the smoke deflector assembly 7 is different, and the movement of the smoke deflector assembly 7 is replaced by translational motion instead of the rotational motion of Example 1. Specifically, the two smoke deflector brackets in Example 1 are replaced with four smoke deflector supports 73, each of which forms a pair. Each pair of smoke deflector supports 73 is fixedly connected to the upper and lower edges of the lower air inlet 10. Each smoke deflector support 73 is provided with a vertical slot 731. The smoke deflector 71 is provided with a positioning member 712 at the position corresponding to the smoke deflector support 73. The positioning member 712 is slidably connected to the vertical slot 731, thereby allowing the smoke deflector 71 to be arranged at the lower air inlet 10 with vertical translational motion.

[0064] When the oil screen assembly 4 is opened as the panel assembly 1 extends forward, the oil screen assembly 4 can drive the smoke guide plate 71 to move along the vertical sliding groove 731 toward the interior of the smoke collection hood 1, thereby causing the smoke guide plate 71 to open the lower air inlet 10 to side-suction oil smoke. When the oil screen assembly 4 is reset as the panel assembly 1 retracts toward the interior of the smoke collection hood 1, the oil screen assembly 4 can drive the smoke guide plate 71 to move along the vertical sliding groove 731 toward the lower air inlet 10, thereby causing the smoke guide plate 71 to close the lower air inlet 10, preventing smoke and dust from entering the smoke collection hood 1 through the lower air inlet 10, and at the same time improving the appearance of the submersible smoke extractor.

[0065] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all fall within the scope of protection of the present invention.
