Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to an oil fume extraction device. Background Technology

[0002] Range hoods are kitchen appliances that quickly remove and exhaust harmful fumes produced during cooking, such as those from stovetops and stir-fries, into the outdoors, thus purifying the kitchen environment. They feature an openable / closed air deflector, the opening and closing time of which can be adjusted according to the stove's combustion status. Current range hoods use infrared sensors to collect temperature data at the burner area, determining whether the stove is on and controlling the air deflector's operation accordingly.

[0003] However, for side-suction range hoods with air deflectors on the market, the deflector needs to cover most of the cooktop when opened, forming a smoke-collecting chamber. Therefore, if the deflector opens at too large an angle, the sensor's detection area is easily blocked, making intelligent speed adjustment impossible. If the deflector opens at too small an angle, the smoke-collecting chamber becomes smaller, affecting the smoke extraction effect. To solve this problem, two sets of sensors can be installed. One set of sensors is located inside the deflector to detect the temperature at the burner when the deflector is open, and the other set of sensors is located outside the deflector to detect the temperature at the burner when the deflector is closed. This requires two sets of sensors to achieve the same temperature detection purpose, resulting in a complex structure and high cost.

[0004] Therefore, there is an urgent need for a fume extraction device to solve the above problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a fume extraction device that can effectively solve the problem of needing to set two sets of sensors to detect the temperature of the stove burner position when the air guide plate is in different states, thereby reducing the cost and structural complexity of the fume extraction device.

[0006] The above-mentioned technical problems are solved by the following technical solutions:

[0007] A fume extraction device, comprising:

[0008] A smoke collection hood has a smoke collection chamber. The side of the smoke collection hood facing the stove burner is provided with an air intake and a mounting plate. The air intake is connected to the smoke collection chamber and is located on the rear side of the mounting plate. A temperature sensing module is provided on the mounting plate for detecting the temperature of the stove burner below the mounting plate.

[0009] An air guide plate is movably mounted on the smoke hood and can be switched between a first position and a second position. When the air guide plate is in the first position, it is located behind the temperature sensing module to close the air intake and prevent interference with the detection area of ​​the temperature sensing module. When the air guide plate is in the second position, it is located in front of the temperature sensing module to open the air intake and prevent interference with the detection area of ​​the temperature sensing module.

[0010] Compared with the prior art, the oil fume extraction device of this utility model has the following beneficial effects:

[0011] This fume extraction device includes a fume hood and an air guide plate. The fume hood has a fume collection chamber. An air intake and a mounting plate are located on the side of the fume hood facing the cooktop burner. The air intake communicates with the fume collection chamber and is located behind the mounting plate. A temperature sensing module is mounted on the mounting plate to detect the temperature of the cooktop burner below the mounting plate. The air guide plate is movably mounted on the fume hood and can switch between a first position and a second position. In the first position, the air guide plate is located behind the temperature sensing module to close the air intake and avoid interference with the module's detection area. After leaving the first position, the air guide plate moves towards the front of the air intake to finally reach the second position. In the second position, the air guide plate is located in front of the temperature sensing module to open the air intake and avoid interference with the module's detection area. In the first position, with the air guide plate behind the temperature sensing module, the air guide plate does not obstruct the temperature sensing module, allowing the module to perform real-time temperature detection of the cooktop burner below the mounting plate. The air guide plate is located in the second position, in front of the temperature sensing module. The air guide plate does not obstruct the temperature sensing module, which can still perform real-time temperature detection of the burner head below the mounting plate. This fume extraction device effectively achieves temperature detection of the burner head position using a single temperature sensing module in different air guide plate states. This reduces the production cost and structural complexity of the fume extraction device. Furthermore, regardless of the air guide plate's position, its movement can be adjusted based on the real-time temperature detected by the temperature sensing module.

[0012] In one embodiment, the mounting plate is tilted downwards from front to back, and the temperature sensing module is located above the air intake in the vertical direction.

[0013] In one embodiment, the fume extraction device further includes a drive assembly that drives the air guide plate to move to the second position, wherein the air guide plate is tilted backward at its upper vertical position.

[0014] In one embodiment, the side of the smoke hood facing the stove burner also includes a front side plate of the smoke hood, the front side plate being inclined downwards in a direction from back to front, and the front side plate avoiding the air guide plate located at the second position.

[0015] In one embodiment, the temperature sensing module includes a temperature sensing substrate, a temperature sensing probe, and a probe sealing ring. The temperature sensing probe is disposed on the temperature sensing substrate, the temperature sensing substrate is connected to the mounting plate, the probe sealing ring is sleeved on the temperature sensing probe, and the temperature sensing probe is sealed through the mounting through hole of the mounting plate.

[0016] The fume extraction device also includes a protective cover, which is located inside the smoke collection chamber and connected to the mounting plate to form a closed protective chamber, and the temperature sensing substrate is located inside the protective chamber.

[0017] In one embodiment, the inner wall of the mounting through hole is provided with a first stepped surface, the outer wall of the temperature sensing probe is provided with a second stepped surface, and the probe sealing ring is sandwiched between the first stepped surface and the second stepped surface.

[0018] In one embodiment, the temperature sensing module further includes a probe support member located on the side of the temperature sensing substrate near the mounting plate. The probe support member presses against the temperature sensing probe so that the temperature sensing probe abuts against the first stepped surface of the mounting through hole.

[0019] In one embodiment, the probe support is a ring structure, and the probe support is sleeved on the outside of the temperature sensing probe.

[0020] In one embodiment, a fixing protrusion is provided on the mounting plate, the temperature sensing substrate is located on the fixing protrusion, and a fixing member passes through the temperature sensing substrate and is inserted into the fixing protrusion.

[0021] In one embodiment, the mounting plate is further provided with a lighting module, which is located in front of the temperature sensing module. When the air guide plate is in the second position, the air guide plate is located in front of the lighting module. Attached Figure Description

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0037] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0038] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] like Figure 1 and Figure 2 As shown, the top-side dual-suction fume extraction device 100 has two air inlets, one at the top and one at the bottom, including a bottom air inlet 102 and an air intake 101. Both the air intake 101 and the bottom air inlet 102 are connected to the smoke collection chamber of the fume hood 1. When the amount of oily smoke is small, the air intake 101 is closed by the air guide plate 2, meaning the air intake 101 does not open, and all the oily smoke enters the smoke collection chamber through the bottom air inlet 102. However, when the amount of oily smoke is large, the air intake 101 opens, and the oily smoke that cannot be sucked into the bottom air inlet 102 rises to the vicinity of the air intake 101 and enters the smoke collection chamber through the air intake 101.

[0040] like Figure 3 As shown in one embodiment of this application, a fume extraction device 100 is provided, including a fume hood 1 and an air guide plate 2. The fume hood 1 has a fume collection chamber. An air intake 101 and a mounting plate 11 are provided on the side of the fume hood 1 facing the stove burner. The air intake 101 communicates with the fume collection chamber and is located behind the mounting plate 11. A temperature sensing module 4 is provided on the mounting plate 11 for detecting the temperature of the stove burner below the mounting plate 11. The air guide plate 2 is movably mounted on the fume hood 1 and can switch between a first position and a second position. In the first position, the air guide plate 2 is located behind the temperature sensing module 4 to close the air intake 101 and avoid interference with the detection area of ​​the temperature sensing module 4. After the air guide plate 2 leaves the first position, it moves towards the front of the air intake 101 to finally be located in the second position. When the air guide plate 2 is in the second position, it is located in front of the temperature sensing module 4 so as to open the air intake 101 without interfering with the detection area of ​​the temperature sensing module 4.

[0041] In the first position, the air guide plate 2 is located behind the temperature sensing module 4. The air guide plate 2 does not obstruct the temperature sensing module 4, which can perform real-time temperature detection of the stove burner below the mounting plate 11. In the second position, the air guide plate 2 is located in front of the temperature sensing module 4. Again, the air guide plate 2 does not obstruct the temperature sensing module 4, and the temperature sensing module 4 can still perform real-time temperature detection of the stove burner below the mounting plate 11. The fume extraction device 100 provided in this embodiment can effectively detect the temperature of the stove burner position using only one temperature sensing module 4 in different states of the air guide plate 2. This reduces the production cost and structural complexity of the fume extraction device 100. Furthermore, regardless of the position of the air guide plate 2, its movement can be adjusted according to the real-time temperature detected by the temperature sensing module 4.

[0042] The fume extraction device 100 typically has two burners. The temperature sensing module 4 is positioned centrally relative to the two burners, its detection angle precisely illuminating the two burners arranged to the left and right of the cooktop. The temperature sensing module 4 continuously monitors the heat radiation from the burners and logically determines the amount of cooking fumes based on temperature curve changes. If the logic determines that the fumes are minimal, a low-fumes mode is triggered; the air guide plate 2 remains in its first position, and the air intake vent 101 is closed. If the logic determines that the fumes are heavy, a high-fumes mode is triggered; the air guide plate 2 moves out of its first position, and the air intake vent 101 opens, more effectively intercepting the fumes.

[0043] Optionally, the mounting plate 11 is inclined downwards from front to back, and the temperature sensing module 4 is located vertically above the air intake 101. When the fume extraction device 100 is in use, the fumes that cannot be sucked into the bottom air inlet 102 will rise to the vicinity of the air intake 101, and a lot of fumes will roll horizontally at the front end of the air intake 101. In order to reduce the escape of these horizontally rolled fumes, the mounting plate 11 is inclined downwards to form a mating cavity with the front side plate 12 of the fume collection hood 1. The mating cavity provides space for the fumes to roll and can change the direction of the fumes when they escape.

[0044] In one embodiment, the temperature sensing module 4 is adjusted according to the interference range between its detection area and the side of the fume hood 1 facing the stove burner. If the detection area of ​​the temperature sensing module 4 covers the air guide plate 2 enclosed at the air intake 101, the installation position of the temperature sensing module 4 can be moved forward on the mounting plate 11. Alternatively, if the detection area of ​​the temperature sensing module 4 covers the air guide plate 2 enclosed at the air intake 101, the downward tilt angle of the side of the fume hood 1 facing the stove burner at the air intake 101 is reduced so that the detection area of ​​the temperature sensing module 4 does not cover the air guide plate 2 located at the first position.

[0045] Optionally, the fume extraction device 100 also includes a drive assembly 3, which drives the air guide plate 2 to move. The air guide plate 2 moves to a second position, where its upper vertical end tilts backward. Figure 2 As shown, the detection area of ​​the temperature sensing module 4 expands radially from top to bottom from the position where the temperature sensing module 4 is set. The lower end of the air guide plate 2 is tilted forward to effectively expand the detection space below and effectively avoid the detection area of ​​the temperature sensing module 4.

[0046] In one embodiment, the drive assembly 3 includes a drive member and a connecting rod. The drive member is connected to the air guide plate 2 via the connecting rod. The connecting rod includes a first connecting rod and a second connecting rod that are rotatably connected. The first end of the first connecting rod, which is not connected to the second connecting rod, is connected to the air guide plate 2. The second end of the second connecting rod, which is not connected to the first connecting rod, is connected to the drive member. The drive member is used to drive the second connecting rod to rotate around its second end, thereby switching the air guide plate 2 between a first position and a second position. The drive member is a drive motor, and its second end is connected to the output shaft of the drive motor. The drive motor drives the second connecting rod to rotate until the air guide plate 2 moves to the air intake 101, thereby closing the air intake 101. The air guide plate 2 is connected to the first connecting rod via the bending rod 31 of the drive assembly 3. One end of the bending rod 31 is connected to the air guide plate 2, and the relative position of the bending rod 31 and the air guide plate 2 is fixed. The other end of the bending rod 31 is rotatably connected to the smoke hood 1, so that the bending rod 31 can drive the air guide plate 2 to rotate relative to the smoke hood 1 under the drive of the first connecting rod, thereby realizing the switching of the air guide plate 2 between the first position and the second position.

[0047] Optionally, such as Figure 3 As shown, the side of the fume hood 1 facing the stove burner also includes a front side plate 12. The front side plate 12 slopes downwards from back to front, avoiding the air guide plate 2 located in the second position. The lower vertical end of the front side plate 12 slopes forward, which not only expands the mating cavity formed with the mounting plate 11, increasing the space for oil fume turbulence and preventing oil fume from escaping, but also provides more space for the air guide plate 2 to move to the second position, preventing the air guide plate 2 from obstructing the detection area.

[0048] Optionally, such as Figure 4 As shown, the temperature sensing module 4 includes a temperature sensing substrate 41, a temperature sensing probe 42, and a probe sealing ring 43. The temperature sensing probe 42 is disposed on the temperature sensing substrate 41, and the temperature sensing substrate 41 is connected to the mounting plate 11. The probe sealing ring 43 is sleeved on the temperature sensing probe 42, and the temperature sensing probe 42 is sealed and inserted into the mounting through hole 112 of the mounting plate 11. (Refer to...) Figure 3 The fume extraction device 100 also includes a protective cover 13, which is located inside the smoke collection chamber and connected to the mounting plate 11 to form a closed protective chamber. The temperature sensing base plate 41 is located inside the protective chamber.

[0049] In one embodiment, the temperature sensing module 4 is an infrared temperature sensing module. The temperature sensing probe 42 measures the temperature by detecting the infrared radiation emitted by the stove burner. Therefore, during installation, it is necessary to ensure that the temperature sensing probe 42 is not obstructed by the mounting plate 11. The temperature sensing substrate 41 is signal-connected to the temperature sensing probe 42 and does not need to be exposed. Therefore, during installation, the temperature sensing substrate 41 is placed inside the protective cavity to avoid contamination by rising oil fumes. To facilitate the insertion of the temperature sensing probe 42 into the mounting through hole 112, there is an installation gap between the temperature sensing probe 42 and the inner wall of the mounting through hole 112. The probe sealing ring 43 is clamped between the temperature sensing probe 42 and the inner wall of the mounting through hole 112 to further fill the installation gap and prevent oil fumes from escaping into the protective cavity through the installation gap. The probe sealing ring 43 can be an O-ring, which has excellent sealing performance, long service life, is reusable, and has a wide temperature range (-60℃ to 220℃), and can achieve sealing against various chemical media such as oil, water, and air.

[0050] In one embodiment, the inner wall of the mounting through hole 112 is provided with a first stepped surface 1121, the outer wall of the temperature sensing probe 42 is provided with a second stepped surface 421, and the probe sealing ring 43 is sandwiched between the first stepped surface 1121 and the second stepped surface 421. Figure 4 As shown, the probe sealing ring 43 is sleeved on the outside of the temperature sensing probe 42 and located on the second stepped surface 421. Along the thickness direction of the mounting plate 11, the mounting through hole 112 is a stepped hole. The mounting through hole 112 includes a first mounting hole and a second mounting hole that are connected. The first mounting hole is located on the side of the mounting plate 11 near the temperature sensing substrate 41, and the diameter of the first mounting hole is larger than the diameter of the second mounting hole. Therefore, when assembling the temperature sensing module 4, the probe sealing ring 43 can be sleeved on the temperature sensing probe 42 first, and then inserted from one side of the first mounting hole, so that the probe sealing ring 43 is pressed against the first stepped surface 1121 by the temperature sensing probe 42, and the probe sealing ring 43 will not come off from the mounting through hole 112.

[0051] Optionally, the temperature sensing module 4 further includes a probe support 44, which is located on the side of the mounting plate 11 near the temperature sensing substrate 41. The probe support 44 presses against the temperature sensing probe 42 so that the temperature sensing probe 42 abuts against the first stepped surface 1121 of the mounting through hole 112. The temperature sensing substrate 41 is fixed to the mounting plate 11 by a fixing member 45. The force applied by the fixing member 45 to the side of the temperature sensing substrate 41 away from the mounting plate 11 is transmitted to the probe support 44, causing the probe support 44 to press against the temperature sensing probe 42. This causes the probe sealing ring 43 located between the second stepped surface 421 and the first stepped surface 1121 to undergo a certain axial deformation, ensuring the sealing effect of the probe sealing ring 43 on the mounting gap.

[0052] In one embodiment, the probe support 44 is a ring structure, and the probe support 44 is sleeved on the outside of the temperature sensing probe 42. Specifically, as shown... Figure 4 and Figure 5 As shown, the temperature sensor 42 includes a temperature sensor pin 422 and a probe portion passing through the mounting through hole 112. The temperature sensor 42 is connected to the temperature sensor substrate 41 via the temperature sensor pin 422. The probe support 44 completely surrounds the temperature sensor pin 422 in the circumferential direction of the temperature sensor 42. The probe support 44 is adjusted according to the length of the temperature sensor pin 422, which not only fixes the temperature sensor 42 but also protects the temperature sensor pin 422 from damage during assembly.

[0053] In another embodiment, the probe support 44 may also be a semi-circular structure, that is, the probe support 44 is sleeved on the outside of the temperature sensing probe 42, but does not completely surround the temperature sensing pin 422 in the circumferential direction of the temperature sensing probe 42.

[0054] In one embodiment, a positioning groove is provided on the side of the temperature sensing substrate 41 facing the temperature sensing probe 42. When the probe support 44 surrounds the outside of the temperature sensing pin 422, one end of the probe support 44 abuts against the temperature sensing substrate 41 and is located in the positioning groove, and the other end of the probe support 44 abuts against the probe portion of the temperature sensing probe 42 inserted into the mounting through hole 112, so as to use the positioning groove to position the relative position of the probe support 44 and the temperature sensing pin 422.

[0055] In another embodiment, the fume extraction device 100 further includes a fixing protrusion 111 disposed on the mounting plate 11. The fixing protrusion 111 has fixing holes 1111. The temperature sensing substrate 41 is located on the fixing protrusion 111. The fixing member 45 passes through the temperature sensing substrate 41 and is inserted into the fixing holes 1111, and is connected to the mounting plate 11 through the fixing holes 1111. The temperature sensing substrate 41 has multiple through holes 411 and fixing holes 1111, and the positions of the multiple through holes 411 and the multiple fixing holes 1111 correspond one-to-one. The height of the fixing protrusion 111 is adjusted according to the length of the temperature sensing pin 422, which can support the temperature sensing substrate 41 to prevent the temperature sensing pin 422 from being squeezed by the temperature sensing substrate 41 during assembly.

[0056] Furthermore, the fume extraction device 100 also includes a lighting module 5, which is mounted on the mounting plate 11 and located in front of the temperature sensing module 4. When the air guide plate 2 is in the second position, the air guide plate 2 is located in front of the lighting module 5. Figure 6 As shown, the lighting module 5 includes a lighting lamp, the size and installation position of which can be adjusted according to the needs of the lighting range. In this embodiment, when the air guide plate 2 is in the second position, the air guide plate 2 is tilted forward at its lower vertical end to avoid obstructing the lighting and to expand the lighting area of ​​the lighting module 5.

[0057] In one embodiment, the mounting plate 11 is tilted downwards from front to back, so the lighting module 5 is located above the air intake 101 in the vertical direction. The mounting plate 11 and the front side plate 12 of the fume hood 1 form a mating cavity, which provides space for the swirling of oil fumes. When the lighting illuminates the surrounding environment, it makes the oil fumes swirling on the top of the fume extraction device 100 more noticeable, while the air guide plate 2 can block the user's view and prevent the user from directly seeing the oil fumes.

[0058] Reference Figure 1 When the fumes are low, the top air guide plate 2 closes, while the lighting still provides illumination. The fumes are absorbed by the bottom air inlet 102. (Refer to...) Figure 2 When there is a lot of cooking fumes, the air deflector 2 opens, the lighting function is still maintained, and the users cannot see the rolling of cooking fumes, thus reducing user dissatisfaction.

[0059] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0060] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
