Description

Technical Field

[0001] This invention relates to the field of electrical technology, and in particular to a smoke hood and a range hood. Background Technology

[0002] A range hood is a kitchen appliance used to purify the kitchen environment. It is usually installed above the gas stove to quickly remove and exhaust the waste produced by the burner and the harmful fumes generated during cooking, thereby reducing pollutants in the kitchen, purifying the air, and improving the user experience.

[0003] A range hood typically includes a smoke collection hood and a fan assembly mounted on top of the hood. The smoke collection hood is installed above the cooktop and has a smoke inlet and a smoke collection chamber communicating with the smoke inlet. An air outlet is located at the top of the hood. The fan assembly includes a fan box mounted on top of the hood and a fan housed within the fan box. When the fan is running, cooking fumes enter the smoke collection chamber from the smoke inlet and are then exhausted to the outside by the fan.

[0004] When installing range hoods in the kitchen, the fan box is usually placed inside the kitchen wall cabinet to save installation space and improve aesthetics. The smoke collection hood is located below the wall cabinet, and the gap between the top of the smoke collection hood and the wall cabinet is usually small. Over time, some grease escapes upwards and adheres to the top of the smoke collection hood, causing it to accumulate a lot of grease. Because the gap between the top of the smoke collection hood and the wall cabinet is small, the top of the smoke collection hood is difficult to clean, affecting the long-term user experience. Furthermore, since the control device for operating the range hood is usually installed at the top front of the smoke collection hood, when the control device needs maintenance or replacement, the entire smoke collection hood must be removed, affecting the convenience of maintenance and replacement. Summary of the Invention

[0005] The purpose of this invention is to provide a smoke hood and a range hood to improve the ease of cleaning the top of the smoke hood and to improve the ease of disassembly, assembly and maintenance of the control device inside the smoke hood.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A smoke collection hood includes a smoke collection body and a smoke collection head that is rotatably and detachably installed on the front side of the top of the smoke collection body. The smoke collection body has a smoke collection cavity inside and a side air inlet is provided on the front side of the smoke collection body. The smoke collection head can rotate relative to the smoke collection body so that the smoke collection head can switch between a horizontal state and an inclined state that is set at an acute angle relative to the smoke collection body.

[0008] As an optional technical solution for a smoke collection hood, the smoke collection head is rotatably connected to the smoke collection body via a hinge, and the smoke collection hood also includes a retractable flexible connector, which is connected between the smoke collection head and the smoke collection body, and the flexible connector closes the circumferential gap between the smoke collection head and the smoke collection body.

[0009] As an optional technical solution for a smoke hood, the lower side of the smoke collection head is provided with a top air inlet, the flexible connector is surrounded to form a ventilation channel, the inner cavity of the smoke collection head is connected to the top air inlet, and the inner cavity of the smoke collection head is sealed and connected to the smoke collection chamber through the ventilation channel.

[0010] As an optional technical solution for a smoke collection hood, the smoke collection head is located entirely outside the smoke collection body, and the smoke collection head has an electrical mounting cavity for installing a control device, which is isolated from the smoke collection hood.

[0011] As an optional technical solution for a smoke collection hood, side baffles are connected to both the left and right sides of the smoke collection body. When the smoke collection head is in the horizontal state, the orthographic projections of the smoke collection body and the smoke collection head onto the plane where the side baffles are located are both located inside the side baffles.

[0012] And / or, the front side of the smoke hood is also provided with an auxiliary air inlet, which is located above the side air inlet and is always in an open state.

[0013] As an optional technical solution for a smoke collection hood, the inner cavity of the smoke collection head forms an electrical installation cavity for installing a control device. An inspection port is provided at the top of the smoke collection head, which is connected to the electrical installation cavity. An inspection plate is installed at the top of the smoke collection head, and the inspection plate can selectively open or close the inspection port.

[0014] A range hood, including the smoke collection hood as described above.

[0015] As an optional technical solution for range hoods, a temperature sensing module is installed at the front end of the smoke collection head. The temperature sensing module includes a temperature detection element, which can rotate relative to the smoke collection head around a first axis extending in the left-right direction. The temperature detection element can detect the temperature of the stovetop downwards.

[0016] As an optional technical solution for a range hood, the temperature sensing module includes a mounting box, which is installed on the smoke collection head. A light-transmitting hole is provided on the lower side of the mounting box. The temperature detection element is rotatably installed in the mounting box around the first axis, and the temperature detection element detects the temperature of the stove through the light-transmitting hole.

[0017] As an optional technical solution for a range hood, the temperature sensing module can be slidably installed on the smoke collection head along the front-back extension direction of the smoke collection head. The front end of the smoke collection head is provided with a mounting groove, which penetrates the front side and the lower side of the smoke collection head. The temperature sensing module can slide and switch between the initial position accommodated in the mounting groove and the extended position extending forward from the smoke collection head.

[0018] The beneficial effects of this invention are as follows:

[0019] The fume hood provided by this invention features a rotatable connection between the fume collection head and the main body, allowing the collection head to switch between horizontal and tilted states. Specifically, when the range hood is not in use, the collection head can be in a horizontal position to maintain the aesthetic appearance of both the fume hood and the range hood. When cleaning the top of the fume hood is required, the collection head can be rotated to a tilted position to increase the distance between the collection head and the upper kitchen cabinets, thus improving the ease of cleaning the top of the collection head. Furthermore, since the collection head and the main body are detachably connected, when the control device inside the collection head needs maintenance, only the collection head needs to be operated, without disassembling the main body and the extraction mechanism, improving the convenience of disassembly, assembly, and maintenance of the control device. Moreover, when the collection head is rotated to a tilted position, the distance between the collection head and the stovetop decreases, thus better preventing fumes from escaping upwards and improving the fume collection effect of the range hood. In other words, when the amount of fumes is large, the collection head can also be rotated to a tilted position to enhance the fume collection effect of both the fume hood and the range hood.

[0020] The range hood provided by the present invention, by adopting the above-mentioned smoke collection hood, can improve the ease of cleaning the range hood, improve the ease of replacing and maintaining the control device, and enhance the smoke collection efficiency of the range hood.

[0040] Example 1

[0041] like Figures 1 to 4 As shown, this embodiment provides a range hood that can be applied in the kitchen of daily home life to purify the kitchen environment and improve the cooking experience. The range hood includes a smoke collection hood 2, an extraction mechanism 200, and a control device. The smoke collection hood 2 is used to collect smoke, the extraction mechanism 200 is installed at the top of the smoke collection hood 2 to extract the fumes, and the control device is installed inside the smoke collection hood 2 to control the operation of the range hood.

[0042] Specifically, the smoke hood 2 includes a smoke collection body 21 and a smoke collection head 22 that is rotatably and detachably installed on the front side of the top of the smoke collection body 21. The smoke collection body 21 has a smoke collection chamber inside, and a side air inlet 211 communicating with the smoke collection chamber is opened on the front side. The smoke collection head 22 can rotate relative to the smoke collection body 21 so that the smoke collection head 22 can switch between a horizontal state and an inclined state that is set at an acute angle relative to the smoke collection body 21.

[0043] The top of the smoke collection body 21 has an exhaust vent that communicates with the smoke collection chamber. The extraction mechanism 200 includes a bellows and a fan installed inside the bellows. The bellows is installed on the top of the smoke collection body 21, and the fan's inlet is connected to the exhaust vent. A control device is installed on the smoke collection head 22 and communicates with the fan. The front side of the smoke collection head 22 has a control area for operating the control device. When the range hood is running, the fan starts and creates negative pressure at the side air inlet 211. Under the action of negative pressure, external fumes enter the smoke collection chamber through the side air inlet 211 and are then extracted to the outside by the fan.

[0044] The smoke collection hood 2 and the range hood provided in this embodiment are rotatably connected to the smoke collection body 21 via the smoke collection head 22, so that the smoke collection head 22 can switch between a horizontal state and an inclined state. When the range hood is not in use, the smoke collection head 22 can be kept horizontal to maintain the aesthetic appearance of the smoke collection hood 2 and the range hood. When cleaning the top of the smoke collection hood 2 is required, the smoke collection head 22 can be rotated to an inclined position to increase the distance between the smoke collection head 22 and the upper kitchen cabinets, thereby improving the ease of cleaning the top of the smoke collection head 22. At the same time, since the smoke collection head 22 is detachably connected to the smoke collection body 21, when the control device inside the smoke collection head 22 needs to be repaired, only the smoke collection head 22 can be operated without disassembling the smoke collection body 21 and the exhaust mechanism 200, improving the ease of disassembly and maintenance of the control device. Furthermore, when the smoke collection head 22 is rotated to an inclined position, the distance between the smoke collection head 22 and the stove is reduced, which helps to better prevent the oil fumes from escaping upwards and improves the smoke collection effect of the range hood. That is, when the amount of oil fumes is large, the smoke collection head 22 can also be rotated to an inclined position to enhance the smoke collection effect of the smoke collection hood 2 and the range hood.

[0045] In this embodiment, the range hood also includes a flap mechanism, which comprises a flip panel 4 and a flap drive assembly. The flip panel 4 is rotatably mounted on the smoke collection hood 2, and the flap drive assembly can drive the flip panel 4 to rotate to selectively open or close the side air inlet 211. The flap mechanism allows for the selective opening or closing of the side air inlet 211, enhancing the overall aesthetics of the range hood when not in use and facilitating cleaning. In other embodiments, the range hood may not have a flap mechanism, meaning the side air inlet 211 remains open at all times.

[0046] Furthermore, the main smoke collection body 21 is also equipped with an auxiliary air inlet 212, which is located above the main air inlet and is always in a normally open state. When the amount of oil smoke is small, the flip panel 4 does not need to be opened, and the oil smoke enters the smoke collection hood 2 through the auxiliary air inlet 212 to achieve the function of oil smoke extraction; when the amount of oil smoke is large, the flip panel 4 is opened, and the side air inlet 211 and the auxiliary air inlet 212 simultaneously draw in air.

[0047] By setting up the auxiliary air inlet 212, the flexibility of the range hood can be improved. Simultaneously, when the smoke collection head 22 is tilted downwards, it can act as a guide vane for the auxiliary air inlet 212, enhancing the smoke collection effect and reducing the probability of smoke escape. In this embodiment, the tilted smoke collection head 22 can be used for cleaning and also enhances the smoke collection effect of the range hood.

[0048] The auxiliary air inlet 212 is preferably an elongated hole extending vertically, and multiple auxiliary air inlets 212 are spaced apart in the left-right direction. In other embodiments, the auxiliary air inlet 212 may also be an elongated hole extending in the left-right direction. The present invention does not limit the specific structure of the side air inlet 211, the auxiliary air inlet 212, and the flap mechanism.

[0049] Furthermore, side baffles are connected to both the left and right sides of the smoke collection body 21. When the smoke collection head 22 is in a horizontal state, the orthographic projections of the smoke collection body 21 and the smoke collection head 22 onto the plane of the side baffles are both located inside the side baffles. This further improves the aesthetic appearance of the smoke collection hood 2 and the range hood, and helps prevent fumes from escaping from the sides, thus improving the smoke collection effect.

[0050] In this embodiment, the smoke collection head 22 has an electrical mounting cavity, which is located entirely in front of the smoke collection body 21 and is separated from the smoke collection hood 2. This arrangement allows the smoke collection head 22 to be individually manufactured according to the installation requirements of the control device, while the smoke collection body 21 can be individually manufactured according to the smoke collection requirements and the installation requirements of the extraction mechanism 200. The assembly between the smoke collection head 22 and the smoke collection body 21 only requires a rotatable connection between the two, simplifying the manufacturing and assembly of the smoke collection hood 2 and reducing the manufacturing and assembly difficulty of the smoke collection hood 2. At the same time, since the smoke collection cavity and the electrical mounting cavity are not connected, the fumes will not enter the electrical mounting cavity, thereby ensuring that the fumes will not pollute the electrical mounting cavity, improving the electrical safety of the control device, and further improving the ease of cleaning the smoke collection head 22.

[0051] To further improve the convenience of maintenance and replacement of the structure within the electrical installation cavity, preferably, the top of the smoke collection head 22 is provided with an inspection port, which communicates with the electrical installation cavity. An inspection plate is installed at the top of the smoke collection head 22, which can selectively open or close the inspection port. With this arrangement, when it is necessary to inspect the components within the electrical installation cavity, the smoke collection head 22 can be rotated to an inclined position, and the inspection plate can be opened. The components within the electrical installation cavity can then be inspected through the exposed inspection port without disassembling the smoke collection head 22, effectively improving the convenience of maintenance and replacement of the components within the electrical installation cavity.

[0052] Preferably, the control device can be disassembled and assembled through an inspection port, thus making the inspection port also the disassembly and assembly port for the control device, thereby improving the convenience and efficiency of disassembly and assembly within the smoke collection head 22. Furthermore, the inspection plate is rotatably connected to the top of the smoke collection head 22, allowing the inspection port to be opened or closed by rotation, eliminating the need to remove the inspection plate and improving the convenience of opening or closing the inspection port. In other embodiments, the inspection plate can also be connected to the top plate of the smoke collection head 22 by screws. Preferably, the upper surface of the inspection plate is flush with the top plate of the smoke collection head 22 to avoid protruding edges at the top of the smoke collection head 22 that could cause scratches to the user.

[0053] The lower rear end of the smoke collecting head 22 is connected to the smoke collecting body 21 via a hinge 24. The hinge 24 can be a hinge structure or a pivot structure. In this embodiment, there are no restrictions on the specific rotational connection structure between the smoke collecting head 22 and the smoke collecting body 21, as long as the rotational connection between the smoke collecting head 22 and the smoke collecting body 21 can be achieved.

[0054] To achieve automatic rotation of the smoke collection head 22, the smoke collection hood 2 also includes a rotation drive assembly 23. The rotation drive assembly 23 is used to drive the smoke collection head 22 to rotate. The rotation drive assembly 23 is connected to the control device so that the control device can control the operation of the rotation drive assembly 23, thereby achieving automatic rotation of the smoke collection head 22.

[0055] The rotation drive assembly 23 includes a rotation drive motor 231 and a rotation transmission assembly. The rotation drive motor 231 is mounted on the smoke collection head 22 or the smoke collection body 21. The rotation drive assembly 23 drives the smoke collection head 22 to rotate through the rotation transmission assembly.

[0056] like Figure 4 and Figure 5 As shown, in one embodiment, a rotary drive motor 231 is mounted on the smoke collection body 21 via a motor bracket 234. The transmission assembly includes a transmission gear 232 sleeved on the rotary drive motor 231 and an arc-shaped rack 233 meshing with the transmission gear 232. The opening of the arc-shaped rack 233 faces upward, and the concave side of the arc-shaped rack 233 is provided with a tooth structure that meshes with the transmission gear 232. The front end of the arc-shaped rack 233 is hinged to the smoke collection head 22, and the rear end of the arc-shaped rack 233 slides into the smoke collection body 21. When the rotary drive motor 231 rotates, the transmission rack rotates, causing the arc-shaped gear to slide relative to the smoke collection head 22, thereby pulling or pushing the smoke collection head 22 to flip.

[0057] To better restrict the movement direction of the arc-shaped rack 233, in this embodiment, a limiting member 25 is provided on the smoke collection body 21. The limiting member 25 abuts against the outer convex arc edge of the arc-shaped rack 233 to limit the arc-shaped rack 233 between the transmission gear 232 and the limiting member 25, ensuring that the arc-shaped rack 233 is always meshed with the transmission gear 232 and restricting the movement direction of the arc-shaped rack 233.

[0058] In another embodiment, the rotation drive assembly 23 is a push rod motor. The rotation drive motor 231 of the push rod motor is installed inside the smoke collection head 22. The rotation transmission assembly of the push rod motor includes a telescopic drive rod and a transmission structure connecting the telescopic drive rod and the rotation drive assembly 23. The rotation drive motor 231 is hinged to the smoke collection head 22 via a motor mount, and the end of the telescopic drive rod is hinged to the front side of the smoke collection body 21. This arrangement allows the rotation drive assembly 23 to be completely located outside the smoke collection body 21, thereby simplifying the assembly of the smoke collection hood 2 and preventing oil fumes from contaminating the rotation drive assembly 23. At the same time, the rotation drive motor 231 is installed inside the smoke collection head 22, which facilitates the electrical connection between the rotation drive motor 231 and the control device, further improving the assembly convenience of the rotation drive assembly 23.

[0059] In another embodiment, a rotation drive motor 231 is installed inside the smoke collection head 22, and the transmission component can adopt a linkage structure, with the end of the linkage structure hinged to the front side of the smoke collection body 21. That is, the rotation drive motor 231 drives the linkage structure to move, thereby causing the smoke collection head 22 to rotate.

[0060] like Figure 2 and Figure 3 As shown, in order to improve the reliability of the range hood, the range hood also includes a temperature sensing module 1. The temperature sensing module 1 is installed at the front end of the smoke collection head 22. The temperature sensing module 1 includes a temperature detection element 12. The temperature detection element 12 is rotatably installed in the smoke collection head 22 around a first axis in the left and right direction, and the temperature detection element 12 can detect the temperature of the stove being tested from the downward direction.

[0061] When the front end of the smoke collection head 22 flips downward, it causes the temperature sensing module 1 to flip downward as well. If the temperature detection element 12 is fixed relative to the smoke collection head 22, the detection field of view of the temperature detection element 12 will flip backward, which may cause the detection field of view of the temperature detection element 12 to fail to cover the target detection area. However, in this embodiment, by setting the temperature detection element 12 to rotate around the first axis, when the smoke collection head 22 flips downward, the temperature detection element 12 can be flipped forward around the first axis, so that the center of the detection field of view of the temperature detection element 12 can remain approximately unchanged before and after the smoke collection head 22 flips, ensuring coverage of the target detection area. Furthermore, since the temperature sensing module 1 moves downward with the smoke collection head 22, the distance between the smoke collection head 22 and the stove is reduced, and the detection field of view of the temperature sensing module 1 can cover the target detection area at an angle, thereby reducing the obstruction of the detection light of the temperature sensing module 1 by the flip panel 4. After the flip panel 4 is flipped, the detection field of view of the temperature sensing module 1 can still cover the target detection area, ensuring the reliability of the temperature measurement of the temperature sensing module 1.

[0062] It is understood that in this embodiment, the smoke collection mechanism 100 is located above the gas stove 300, and a temperature sensing module 1 is provided. The gas stove 300 has two burners 301. The target measurement area refers to the detection area covering the two burners. When no cooking utensils are placed on the burner 301, the temperature value detected by the temperature sensing module 1 in the target measurement area is the temperature value of the burner 301. When cooking utensils are placed on the burner 301, the target measurement area covers the cooking utensils, and the temperature detected by the temperature sensing module 1 is mainly the temperature of the cooking utensils.

[0063] In other embodiments, two temperature sensing modules 1 may be arranged at intervals in the left-right direction, with the two temperature sensing modules 1 corresponding to two burners respectively. In this case, the target back area of ​​each temperature sensing module 1 covers the corresponding burner 301 and the cooking utensils located on the burner 301.

[0064] That is, the range hood provided in this embodiment is mounted to the front of the smoke collection head 22 by rotating it, and the temperature sensing module 1 is mounted to the front of the smoke collection head 22. The temperature sensing element can rotate around the first axis, so that when the flip panel 4 is opened, the smoke collection head 22 can be rotated to an inclined state. By rotating the temperature sensing element 12 around the first axis, the obstruction of the detection light of the temperature sensing element 12 when the flip panel 4 is opened can be effectively avoided, the detection reliability of the temperature sensing module 1 can be improved, and the length requirement of the smoke collection head 22 in the front-back direction can be reduced.

[0065] In this embodiment, when the flip panel 4 is not opened, the smoke collection head 22 can be in a horizontal state. At this time, the flip panel 4 will not block the detection light of the temperature sensing module 1. The control device can control the start of the range hood fan and adjust the fan air volume through the detection result of the temperature sensing module 1. When the flip panel 4 is opened, the smoke collection head 22 can be in a tilted state to enhance the smoke collection effect of the smoke collection head 22 and avoid the detection light of the temperature sensing module 1 being blocked by the open flip panel 4.

[0066] The temperature sensing module 1 includes a mounting box 11, which is detachably mounted to the smoke collection head 22. The temperature sensing element 12 is rotatably mounted inside the mounting box 11 around a first axis, thereby better realizing the modularity of the temperature sensing module 1. In other embodiments, the temperature sensing module 1 includes a mounting box 11, the temperature sensing element 12 is mounted inside the mounting box 11, and the mounting box 11 is rotatably mounted inside the smoke collection hood 2 around a first axis. The overall rotation of the temperature sensing module 1 can be driven by a rotation drive structure or manually adjusted.

[0067] like Figure 6 and Figure 7 As shown, to better realize the rotation of the temperature sensing element 12 around the first axis, the temperature sensing module 1 also includes a front-rear adjustment component 13. The front-rear adjustment component 13 is disposed in the mounting box 11, and is used to drive the temperature sensing element 12 to swing around the first axis. Thus, the automatic rotation of the temperature sensing element 12 is realized through the front-rear adjustment component 13, so that the flipping of the smoke collection head 22 and the rotation of the temperature sensing element 12 can be carried out synchronously, improving the adjustment efficiency and automaticity, thereby making it more conducive to improving the accuracy of temperature detection.

[0068] To improve the ease of installation of the front and rear adjustment components 13 and the temperature sensing element 12 within the mounting box 11, in this embodiment, the mounting box 11 includes a detachably connected box body 111 and a box cover 112. The box body 111 has a mounting groove with an opening at the top, and a light-transmitting hole 1111 is provided at the bottom of the box body 11. The box cover 112 is placed over the opening of the mounting groove, and the box body 111 and the box cover 112 together form the aforementioned mounting cavity. In this embodiment, the cover is detachably installed on the upper side of the box body 111. In other embodiments, the box cover 112 may also be installed on one side of the periphery of the box body 111.

[0069] In this embodiment, a mounting base 16 is installed inside the mounting box 11, and the temperature sensing element 12 is rotatably mounted on the mounting base 16 around a first axis. The fixed part of the front-to-back adjustment assembly 13 is installed inside the mounting box 11, and the movable part of the front-to-back adjustment assembly 13 is connected to the temperature sensing element 12 to drive the temperature sensing element 12 to move. By providing the mounting base 16 inside the mounting box 11, the structure of the mounting box 11 can be simplified, and the installation of the temperature sensing element 12 can be made more convenient.

[0070] To simplify the connection structure between the mounting base 16 and the temperature sensing element 12, a hinge 17 is connected to the upper end of the temperature sensing element 12. The upper end of the hinge 17 is hinged to the mounting base 16, which is mounted on the cover. The hinge 17 preferably includes a connecting rod portion 172 and a ball head 171. The ball head 171 is connected to the upper end of the connecting rod portion 172, and the lower end of the connecting rod portion 172 is connected to the upper end of the temperature sensing element 12. A spherical groove is provided on the mounting base 16, and the ball head 171 is rotatably mounted in the spherical groove. By rotatably connecting the ball head 171 to the mounting base 16, the temperature sensing element 12 can rotate not only around a first axis but also around a second axis, simplifying the rotational connection structure of the temperature sensing element 12 relative to the mounting base 16 and reducing costs.

[0071] The mounting base 16 includes a mounting plate portion 161 and a ball seat portion 162 connected to the lower side of the mounting plate portion 161. The upper side of the mounting plate portion 161 is connected to the inner side of the cover. The ball seat portion 162 includes two detachably connected hemispherical seat portions 162, which together form the aforementioned spherical groove. Each ball seat portion 162 is detachably connected to the mounting plate portion 161. This arrangement facilitates the installation of the ball head 171 within the spherical groove and effectively prevents the ball head 171 from rotating out of the spherical groove. It is understood that the structure of the mounting base 16 described above is an exemplary structure, and any existing structure that enables the rotatable installation of the ball head 171 and the mounting base 16 can be applied to this invention.

[0072] Furthermore, in this embodiment, the temperature sensing module 1 also includes a left-right adjustment component 15. The left-right adjustment component 15 is used to drive the temperature detection element 12 to swing around the axis of the second direction, so as to adjust the position of the detection area formed by the temperature detection element 12 on the stove in the left-right direction. This allows for the adjustment of the detection position, enabling the installation and verification of the temperature detection element 12, and ensuring that the detection area of ​​the temperature detection element 12 can cover the stove head 301 to be detected in the left-right direction.

[0073] The front-to-back adjustment assembly 13 and the left-to-right adjustment assembly 15 are electrically telescopic drive rods. The electrically telescopic drive rod of the front-to-back adjustment assembly 13 extends in the front-to-back direction, and its fixed end is hinged to the rear or front side wall of the housing 111, while its movable end is hinged to the temperature sensing element 12. The electrically telescopic drive rod of the left-to-right adjustment assembly 15 extends in the left-to-right direction, and its fixed end is hinged to one side wall of the housing 111, while its movable end is hinged to the temperature sensing element 12. This simplifies the connection between the front-to-back adjustment assembly 13 and the temperature sensing element 12.

[0074] In this embodiment, the field of view of the temperature sensor 12 in the left-right direction covers both burner heads 301, thereby reducing the number of temperature sensors 12 and thus reducing the number of left-right adjustment components 15 and front-back adjustment components 13. In other embodiments, two temperature sensors 12 can be provided, and the two temperature sensors 12 respectively detect the temperature of the two burner heads 301. In this case, two left-right adjustment components 15 are provided to adjust the detection area of ​​the two temperature sensors 12 in the left-right direction respectively. The front-back adjustment components 13 can be provided one-to-one with the temperature sensors 12, or the same front-back adjustment component 13 can drive the two temperature sensors 12 to rotate simultaneously through a transmission component.

[0075] To further improve the accuracy of temperature detection, a recessed groove is provided on the lower side of the mounting box 11, through which a light-transmitting hole 1111 passes. A lower filter 14 is installed inside the recess to filter light, ensuring that only infrared light can pass through the lower filter 14, thereby improving the accuracy of the detection results. Preferably, the lower surface of the lower filter 14 is flush with the lower side of the mounting box 11 to improve the aesthetics.

[0076] In this embodiment, the temperature sensing module 1 also includes an adapter plate, which is installed inside the mounting box 11. The temperature sensing element 12 and the front and rear adjustment assembly 13 are both connected to the adapter plate. The adapter plate is communicatively connected to the control device of the range hood. This simplifies the connection structure between the electrical components in the temperature sensing module 1 and the control device, improves connection convenience, and reduces the number of connection interfaces between the temperature sensing module 1 and the control device.

[0077] Example 2

[0078] like Figure 8 As shown, this embodiment provides a range hood. The range hood provided in this embodiment is a further improvement based on the range hood in Embodiment 1. This embodiment will not repeat the contents that are the same as in Embodiment 1.

[0079] In this embodiment, the temperature sensing module 1 can be slidably installed on the smoke collecting head 22 along the front and rear extension direction of the smoke collecting head 22. The front end of the smoke collecting head 22 is provided with a mounting groove 221, which penetrates the front side and the lower side of the smoke collecting head 22. The temperature sensing module 1 can slide and switch between the initial position accommodated in the mounting groove 221 and the extended position extending forward from the smoke collecting head 22.

[0080] The temperature sensing module 1 provided in this embodiment can be in its initial position when the flip panel 4 is not opened. At this time, the temperature sensing module 1 will not affect the appearance of the range hood or bump into the user due to protruding from the smoke collection head 22, and the temperature sensing module 1 can detect the target detection area downwards. When the flip panel 4 is opened, depending on the opening angle of the flip panel 4, only the smoke collection head 22 can be flipped downwards, only the temperature sensing module 1 can be extended forward relative to the smoke collection head 22, or the smoke collection head 22 can be flipped downwards while the temperature sensing module 1 is extended forward relative to the smoke collection head 22. This improves the flexibility of the smoke collection mechanism 100 and the range hood and effectively avoids the detection light of the temperature sensing module 1 being blocked when the flip panel 4 is opened.

[0081] To enable the automatic extension and retraction of the temperature sensing module 1 relative to the smoke collection head 22, the smoke collection mechanism 100 also includes a telescopic component 3. The temperature sensing module 1 is installed on the smoke collection head 22 through the telescopic component 3. The telescopic component 3 is used to drive the temperature sensing module 1 to move along the front and rear extension direction of the smoke collection head 22. The telescopic component 3 is communicatively connected to the control device.

[0082] In this embodiment, the telescopic assembly 3 includes a telescopic drive motor 31, a telescopic rod 32, and a telescopic transmission component connecting the telescopic drive motor 31 and the telescopic rod 32. The telescopic drive motor 31 is installed inside the smoke collection head 22, and the telescopic rod 32 slides out of the smoke collection head 22 and is connected to the temperature sensing module 1. The drive motor drives the telescopic rod 32 to move in the front-back direction. This reduces the portion of the telescopic assembly 3 exposed outside the smoke collection head 22, reduces the interference of oil fumes on the telescopic assembly 3, and improves the operational reliability of the telescopic assembly 3. Specifically, the telescopic drive motor 31 is installed in the smoke collection head 22, and a rod through-hole is opened on the rear side wall of the mounting groove 221, through which the telescopic rod 32 slides.

[0083] In this embodiment, preferably, the temperature sensing module 1 is installed in the middle of the smoke collection head 22 along the left-right direction, that is, the temperature sensing module 1 detects both burners 301 simultaneously, reducing the number of temperature sensing modules 1 required, thereby reducing costs. In other embodiments, the temperature sensing module 1 can also be arranged in a one-to-one correspondence with the burner 301, that is, two temperature sensing modules 1 are respectively arranged for two burners 301, and the two temperature sensing modules 1 are spaced apart in the left-right direction. The telescopic component 3 is arranged in a one-to-one correspondence with the temperature sensing module 1.

[0084] Furthermore, the telescopic drive motor 31 is installed in the electrical mounting cavity, which shortens the distance between the control device and the telescopic drive motor 31 and improves the convenience of connecting the telescopic drive motor 31 and the control device.

[0085] The temperature sensing module 1 is electrically connected to the control device via a connecting wire. The telescopic rod 32 is a hollow rod with an opening at its first end forming a wiring inlet and an outlet located inside the smoke collection head 22. The second end of the connecting wire passes sequentially through the wiring inlet, the inner cavity of the telescopic rod 32, and the outlet before connecting to the control device. This avoids exposing the connecting wire, improving wiring safety and reliability. Specifically, the first end of the connecting wire is connected to the adapter plate.

[0086] During the extension and retraction of the telescopic rod 32 and the temperature sensing module 1, a portion of the connecting wires located in the telescopic rod 32 move synchronously with the telescopic rod 32. To reduce the probability of the connecting wires being pulled, in this embodiment, a wire fixing structure is provided near the outlet of the telescopic rod 32. The wire fixing structure is used to fix the connecting wires at the outlet, ensuring that the connecting wires between the temperature sensing module 1 and the outlet are fixed relative to the telescopic rod 32. This avoids problems such as pulling, scratching, or tangling of the connecting wires caused by the relative movement of the connecting wires and the telescopic rod 32, thereby improving the safety of the wiring.

[0087] In this embodiment, the telescopic rod 32 and the telescopic drive motor 31 can form part of an electric push rod, that is, the telescopic assembly 3 adopts the structure of an electric push rod. In other embodiments, the transmission connection component can also adopt a gear and rack structure to realize the movement of the telescopic rod 32 in the front-back direction. For example, a rack is provided on the outer wall of the telescopic rod 32, and a gear is rotatably installed inside the smoke collection head 22. The gear is coaxially connected to the motor shaft of the telescopic drive motor 31, and the gear meshes with the rack.

[0088] The present invention does not limit the specific structure of the telescopic component 3. Any structure that can enable the temperature sensing module 1 to extend and retract in the front-to-back direction can be applied to the present invention.

[0089] Example 3

[0090] This embodiment provides a range hood, and the range hood provided in this embodiment is a further improvement based on the range hood in the above embodiments. This embodiment will not repeat the same structure as the above embodiments.

[0091] like Figure 9 As shown, in this embodiment, the smoke collection head 22 is rotatably connected to the smoke collection body 21 via a hinge 24, and the smoke collection hood 2 also includes a retractable flexible connector 26. The flexible connector 26 is connected between the smoke collection head 22 and the smoke collection body 21, and the flexible connector 26 closes the circumferential gap between the smoke collection head 22 and the smoke collection body 21.

[0092] By setting a flexible, extendable connector 26, the circumferential gap between the smoke collection head 22 and the smoke collection body 21 can be sealed, thereby improving the aesthetic appearance of the smoke collection hood 2 and the range hood, and preventing oil fumes or impurities from entering between the smoke collection head 22 and the smoke collection body 21, which would make it difficult for the smoke collection head 22 to fit properly with the smoke collection body 21 when rotated to a horizontal position, thus improving the reliability of the smoke collection hood 2. At the same time, since the flexible connector 26 connects the smoke collection body 21 and the smoke collection head 22, it can further enhance the connection reliability between the smoke collection head 22 and the smoke collection body 21.

[0093] In this embodiment, the flexible connector 26 is formed into a ring shape. The front end of the ring shape is connected to the peripheral edge of the rear end of the smoke collection head 22, and the rear end of the ring shape is connected to the smoke collection body 21. The connection method can be screw connection or adhesive bonding.

[0094] The flexible connector 26 includes multiple connecting parts that are folded and connected sequentially from front to back. Adjacent connecting parts are connected at an angle, and the openings of the two adjacent angles are opposite to each other. Thus, when the smoke collection head 22 is flipped downward, the two adjacent connecting parts unfold relative to each other and the angle formed increases. When the smoke collection head 22 is rotated to a horizontal state, the two adjacent connecting parts close together and fold.

[0095] The flexible connector 26 can be made of thin aluminum or aluminum alloy to improve the overall structural strength of the flexible connector 26 while ensuring that the flexible connection can expand and contract. The flexible connector 26 can also be made of elastic materials, such as rubber or silicone.

[0096] The flexible connector 26 forms a ventilation channel. A connecting opening is located on the front side of the smoke collecting body 21, inside the flexible connector 26 and sealed to the ventilation channel. The inner cavity of the smoke collecting head 22 extends to its rear side, meaning the inner cavity of the smoke collecting head 22 is connected to the smoke collecting chamber via the ventilation channel. A top air inlet is located on the lower side of the smoke collecting head 22, communicating with the inner cavity. In other words, the top air inlet, the inner cavity of the smoke collecting head 22, the ventilation channel, and the smoke collecting chamber are sequentially connected.

[0097] The above configuration allows the fume hood 2 to have both side-suction and top-suction functions, which improves the fume collection effect and thus enhances the fume extraction efficiency. The top air inlet is preferably always open, but a movable baffle can also be installed to selectively open or close the top air inlet.

[0098] It is understood that in this embodiment, the smoke collection body 21 may not be equipped with an auxiliary air inlet 212.

[0099] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
