Description

Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, and in particular to a smoke collection technology for a submersible smoke extraction machine. 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.

[0030] 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.

[0031] like Figure 1-4 As shown, a submersible smoke extractor of this embodiment includes a smoke hood 1 with an air inlet 11 on one side, a panel assembly 2, a driving mechanism 3, an oil screen assembly 4 and a smoke baffle assembly 5. An oil cup 7 for containing oil droplets is detachably connected to the bottom of the smoke hood 1, and a fan assembly 81 is provided inside the smoke hood 1. A fan assembly 81 connected to the fan assembly 81 is provided at the top middle position of the smoke hood 1 for discharging filtered smoke into the atmosphere. The panel assembly 2 is movably arranged on the smoke hood 1 for opening or closing the 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 oil screen assembly 4 is movably arranged between the lower half of the panel assembly 2 and the smoke hood 1, and the smoke baffle assembly 5 is movably arranged between the upper half of the panel assembly 2 and the smoke hood 1. When the driving mechanism 3 drives the panel assembly 2 to move forward to open the air inlet 11, the panel assembly 2 can synchronously drive the oil screen assembly 4 and the smoke baffle assembly 5 to move synchronously. Figure 3-4When the panel assembly 2 moves to the maximum open position, the oil net assembly 4 and the panel assembly 2 are enclosed to form a negative pressure area, and the oil smoke is guided into the interior of the smoke collection hood 1, thereby improving the smoking effect and avoiding the user from hitting his head during the cooking process. At the same time, the smoke baffle assembly 5 and the panel assembly 2 are enclosed to form a smoke collection area to prevent the oil smoke from escaping upward; when the driving mechanism 3 drives the panel assembly 2 to reset backward to close the air inlet 11, the panel assembly 2 can synchronously drive the oil net assembly 4 to perform an upward flip reset movement and the smoke baffle assembly 5 to perform a downward flip reset movement. The panel assembly 2 closes the air inlet 11 to prevent smoke and dust from entering the interior of the smoke collection hood 1. At the same time, the oil net assembly 4 and the smoke baffle assembly 5 retract into the smoke collection hood 1 to ensure the beautiful appearance of the submersible smoke extractor.

[0032] The present embodiment is a submersible smoke extractor, which is configured such that the oil net assembly 4 and the smoke baffle assembly 5 are movably arranged between the panel assembly 2 and the smoke hood 1, and the movement of the panel assembly 2 can synchronously drive the oil net assembly 4 and the smoke baffle assembly 5 to move synchronously, so that when the submersible smoke extractor is working, the oil net assembly 4 and the panel assembly 2 enclose a negative pressure area, and the smoke baffle assembly 5 and the panel assembly 2 enclose a smoke collection area, thereby improving the smoking effect, preventing the smoke from escaping upward, and avoiding the user from easily bumping during the cooking process, thereby improving the user experience. In addition, by only using a drive mechanism 3 to control the movement of the panel 2, the movement of the oil net assembly 4 and the smoke baffle assembly 5 can be synchronously controlled by the panel assembly 2, which is conducive to reducing the number and occupied space of the drive mechanism 3, improving the movement synchronization of each moving part, and reducing manufacturing costs.

[0033] like Figure 2-3 As shown, further, the air inlet 11 is provided at the upper end of the front face of the smoke hood 1, and the area of ​​the air inlet 11 is slightly smaller than the maximum cross-sectional area of ​​the panel assembly 2, so as to ensure that the panel assembly 2 can completely close the air inlet 11, and at the same time prevent 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, so that when the oil smoke flows upward along the slope or arc surface of the smoke hood 1, part of the oil in the oil smoke condenses and flows downward along the slope or arc surface and collects in the oil cup 7, thereby achieving the purpose of preliminary separation of the oil smoke and oil guidance. In this embodiment, the lower end of the front face of the smoke hood 1 is a slope.

[0034] Specifically, an oil screen bracket 12 and a smoke baffle bracket 13 are provided inside the fume hood 1. The oil screen bracket 12 is fixedly connected to the inclined surface of the fume hood 1, near the lower edge of the air inlet 11, and is used to rotatably connect with the oil screen assembly 4. At the same time, it can prevent the oil screen assembly 4 from interfering with the fan assembly 81 when it is retracted into the fume hood 1. The smoke baffle bracket 13 is fixedly connected to the inner side of the top of the fume hood 1, near the upper edge of the air inlet 11, and is used to rotatably connect with the smoke baffle assembly 5. At the same time, it can prevent the smoke baffle assembly 5 from interfering with the fan assembly 81 when it is retracted into the fume hood 1.

[0035] like Figure 2-4 As shown, the panel assembly 2 further comprises 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 and the smoke guide plate assembly 5. Preferably, the panel 21 is a glass panel to enhance the product's aesthetics and facilitate user cleaning. More preferably, to ensure that the panel 21 is fully aligned with the air inlet 11 of the smoke collection chamber 1, sponge strips can be added around the panel 21.

[0036] Preferably, the fixing seat 22 is a rectangular plate so that when the fixing seat 22 is fixedly connected to the back of the panel 21 by bonding, the bonding area is large, thereby improving the connection strength. Specifically, the fixing seat 22 is provided with three press-formed bosses (not shown in the figure) spaced apart and arranged side by side in an upper and lower manner. The lower press-formed boss is located in the lower half of the panel 21 and is fixedly connected to a lower bracket 221 for connecting to the oil screen assembly 4. The upper press-formed boss is located in the upper half of the panel 21 and is fixedly connected to an upper bracket 222 for connecting to the smoke baffle assembly 5. The middle press-formed boss is fixedly connected to a middle bracket 223 for connecting to the drive mechanism 3. In this way, by adding brackets to the three press-formed bosses spaced apart and arranged side by side in an upper and lower manner, the oil screen assembly 4, the smoke baffle assembly 5 and the drive mechanism 3 are respectively connected to the panel assembly 2. In addition, by locating the lower press-formed boss in the lower half of the panel 21 and the upper press-formed boss in the upper half of the panel 21, it is ensured that the oil screen assembly 4 and the smoke baffle assembly 5 do not interfere with each other during rotation.

[0037] like Figure 2-5 As 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, the rotation of the connecting rod assembly 32 is controlled by controlling the forward and reverse rotation of the driver 311. 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.

[0038] 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.

[0039] 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.

[0040] like Figure 4-5 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 two fixing seats 22 are respectively connected to one end 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 air inlet of the smoke hood 1 through the cooperation of the two slide rail assemblies 6 and the two fixing seats 22, 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 the movement of the slide rail assembly 6 connected to the driven rod 322 is controlled by a single driving mechanism 3, thereby achieving the front-to-back telescopic movement of the control panel assembly 2, which helps to reduce manufacturing costs.

[0041] 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 can drive the second slide rail 62 to reciprocate through the sliding block 621, thereby causing the panel assembly 2 to telescope forward and backward.

[0042] 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.

[0043] like Figure 2-4 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 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 flipped open or reset as the panel assembly 2 moves forward and backward, while ensuring that the flipping movement of the oil net 41 is more stable and reliable.

[0044] Specifically, each first slider 42 is provided with a first slide groove 421 arranged along the length direction at one end away from the panel assembly 2, and each oil net bracket 12 is provided with a pin 9 at the upper end, and the pin 9 can be movably inserted into the first slide groove 421. In this way, the first slide groove 421 cooperates with the pin 9 to reliably realize the sliding connection between the first slider 42 and the oil net bracket 12.

[0045] like Figure 6As shown, in this embodiment, the oil net 41 and the two first sliders 42 are independent of each other, and the two first sliders 42 are fixed to the left and right side walls of the oil net 41 by welding or bonding, so as to facilitate the processing and forming of the oil net 41 and the first sliders 42. And one end of each first slider 42 close to the first slide 421 protrudes from the bottom surface of the oil net 41, so that the first slide 421 can be slidably connected with the oil net bracket 12 through the pin 9. A plurality of smoke inlets 411 arranged in the length direction are arranged side by side on the oil net 41 at intervals, and each smoke inlet 411 is located in the middle of the width direction of the oil net 41, and an oil leakage hole 412 is provided at the bottom of the oil net 41 to facilitate the residual oil droplets of the oil net 41 to flow into the inside of the smoke hood 1 through the oil leakage hole 412. In other embodiments, the two first sliders 42 are respectively integrally formed with the oil net 41 (see Figure 7 ), and the two first sliding blocks 42 respectively constitute the left and right side walls of the oil net 41, which can save the manufacturing materials of the oil net 41, simplify the assembly process of the oil net component 4, improve production efficiency, and eliminate the interference of the side walls of the oil net 41 on the first slide groove 421.

[0046] like Figure 2-4 As shown, further, there are two smoke damper brackets 13, each fixedly connected to opposite sides of the inner top side of the smoke hood 1 and close to the upper edge of the air inlet 11. The smoke damper assembly 5 includes a smoke damper 51 and two second sliders 52. The smoke damper 51 is movably disposed between the upper half of the panel 21 and the smoke hood 1. The two second sliders 52 are disposed on the left and right sides of the smoke damper 51, respectively. One end of each second slider 52 is hingedly coupled to the corresponding upper bracket 222, and the other end is slidably coupled to the corresponding smoke damper bracket 13. Thus, through the coordination of the two second sliders 52, the two upper brackets 222, 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, while ensuring that the flipping movement of the smoke damper 51 is more stable and reliable.

[0047] Specifically, each second slider 52 is provided with a second slide groove 521 arranged along the length direction at one end away from the panel assembly 2, and each smoke shield bracket 13 is provided with a pin 9 at the lower end, and the pin 9 can be movably inserted into the second slide groove 521. In this way, the second slide groove 521 cooperates with the pin 9 to reliably realize the sliding connection between the second slider 52 and the smoke shield bracket 13.

[0048] like Figure 8 As shown, in this embodiment, the smoke shield 51 and the two second sliders 52 are independent of each other, and the two second sliders 52 are fixed to the left and right side walls of the smoke shield 51 by welding or bonding. In other embodiments, the two second sliders 52 are respectively integrally formed with the smoke shield 51 (see Figure 9), and the two second sliders 52 respectively constitute the left and right side walls of the smoke baffle 51, which can save the manufacturing materials of the smoke baffle assembly 5, simplify the assembly process, improve production efficiency, and eliminate the interference of the side wall of the smoke baffle 51 on the second slide groove 521.

[0049] like Figure 1-2 As shown, in this embodiment, the maximum dimension of the submersible smoke extractor in the front-to-back direction is less than 250 mm, and its maximum dimension in the vertical direction is 340-400 mm. The length of the air inlet 11 is slightly less than the maximum dimension of the smoke hood 1 in the left-to-right direction, and its width in the vertical direction is slightly less than 30 mm. The corresponding panel 21 has a width in the vertical direction of approximately 300 mm. The length of the panel 21 is equal to the maximum dimension of the smoke hood 1 in the left-to-right direction, ensuring that the panel 21 can fully close the air inlet 11. The maximum dimension of the smoke exhaust device 82 in the front-to-back direction is less than 250 mm, and its maximum dimension in the left-to-right direction is less than 400 mm. The maximum dimension of the smoke exhaust device 82 in the left-to-right direction is less than the maximum dimension of the submersible smoke extractor in the left-to-right direction. The maximum dimension of the smoke exhaust device 82 in the vertical direction is less than 120 mm, ensuring that the smoke hood 1 has sufficient height to install the fan assembly 81. The maximum dimension of the fan assembly 81 in the front-to-back direction is less than 150 mm, allowing it to be accommodated inside the smoke hood 1, ensuring effective air intake and extraction. 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.

[0050] 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 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.

[0051] The following combination Figure 1 and Figure 3-5 To illustrate the working principle of the present embodiment of the submersible smoking machine:

[0052] like Figure 1 and Figure 3-5When the second slide rail 62 is extended forward, the second slide rail 62 is pushed forward and the panel assembly 2 is pushed forward to open the air inlet 11. During the forward movement of the panel assembly 2, the oil screen assembly 4 is driven to turn clockwise through the lower bracket 221 to open the oil screen assembly 4. At the same time, the smoke baffle assembly 5 is driven to turn counterclockwise through the upper bracket 222 to open the smoke baffle assembly 5. When the active rod 321 abuts against the limit portion 312 near the panel assembly 2, the driver 311 stops working. At this time, the panel assembly 2 is in the maximum open position. The oil screen assembly 4 and the panel assembly 2 enclose a negative pressure area and guide the oil smoke into the interior of the smoke collection hood 1 to improve the smoking effect. The smoke baffle assembly 5 and the panel assembly 2 enclose a smoke collecting area to prevent the oil smoke from escaping upward.

[0053] When the submersible smoke extractor is closed, 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 air inlet 11. During the backward retraction of the panel assembly 2, the oil screen assembly 4 is driven to synchronously reset through the lower bracket 221 to retract the oil screen assembly 4 into the smoke hood 1. At the same time, the smoke baffle assembly 5 is driven to synchronously reset through the upper bracket 222 to retract the smoke baffle assembly 5 into the smoke hood 1; when the active rod 321 abuts against the limiting portion 312 away from the panel assembly 2, the driver 311 stops working. At this time, the panel assembly 2 closes the air inlet 11 to prevent smoke and dust from entering the smoke hood 1, and the oil screen assembly 4 and the smoke baffle assembly 5 retract into the smoke hood 1, ensuring the beautiful appearance of the submersible smoke extractor.

[0054] 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.
