[0002] As people's living standards improve, range hoods have become an indispensable appliance in the kitchen. They are usually installed above the kitchen stove and can quickly extract the exhaust gas produced by the gas stove and the oil fumes generated during cooking, thereby purifying the kitchen environment and improving people's comfort while cooking.

[0003] Existing range hoods include electrical components such as control modules, lights, motors, and fan motors. With increasingly complex functions, these components need to be electrically connected via wiring harnesses to transmit power and control signals. As a result, the number of internal wires increases, which can easily lead to tangling and interference between the wires, affecting the safety of the wiring and thus reducing the electrical safety of the range hood, ultimately impacting its usability.

[0004] Therefore, there is an urgent need to provide a range hood that solves the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a range hood with more orderly internal wiring, which can avoid safety hazards caused by messy wiring.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0042] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0043] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0045] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0046] like Figures 1 to 3 As shown, this embodiment provides a range hood, including a main box 8, a housing 1, and a flap 3. The housing 1 is connected to the bottom of the main box 8 and communicates with it. A fan mechanism (not shown) is provided inside the main box 8. A smoke collection chamber 2 is concealed inside the housing 1. A smoke inlet 221 is provided on the front side of the smoke collection chamber 2. The flap 3 is movably connected to the smoke collection chamber 2, and both can be opened or closed relative to the housing 1 by a drive mechanism. When opened, the smoke collection chamber 2 moves out of the housing 1, and the flap 3 flips relative to the smoke collection chamber 2. When fully closed, the flap 3 fits and covers the front side of the housing 1. A decorative cover 9 can be selectively installed on the outside of the main box 8 for aesthetic purposes.

[0047] like Figure 1As shown, in the working state, the flap 3 and the smoke collection chamber 2 are open relative to the housing 1, the smoke collection chamber 2 moves out of the housing 1, and the flap 3 flips relative to the smoke collection chamber 2 to form a larger smoke collection area, effectively improving the smoke collection efficiency. At this time, under the negative pressure of the fan mechanism, the oil fumes generated during cooking can enter the smoke collection chamber 2 through the smoke inlet 221 and be discharged to the exhaust pipe through the main box 8. Figure 2 As shown, in the non-working state, the flap 3 and the smoke collection chamber 2 are closed relative to the housing 1, so that the smoke collection chamber 2 is hidden inside the housing 1, and the flap 3 fits and covers the front side of the housing 1, making the range hood more compact and small when not in use. The thickness of the housing 1 can be made thinner, thereby achieving a thinner body size and reducing the space occupied.

[0048] Combination Figure 4 and Figure 5 The driving mechanism includes a first driving assembly 6 for driving the movement of the flap 3. The first driving assembly 6 includes a first motor 61 and a first swing arm assembly 62. The first motor 61 is installed inside the smoke collection chamber 2. One end of the first swing arm assembly 62 is connected to the output shaft of the first motor 61, and the other end passes through the through hole 211 on the front side of the smoke collection chamber 2 and is hinged to the flap 3. When the output shaft of the first motor 61 rotates, it drives the first swing arm assembly 62 to rotate, and the first swing arm assembly 62 drives the flap 3 to flip relative to the smoke collection chamber 2 to open or close.

[0049] It is worth noting that, apart from the first motor 61, the electrical components of this range hood can be roughly divided into three parts: the electrical components within the flap 3, the electrical components within the housing 1, and the electrical components within the main box 8. Therefore, referring to... Figure 3 , Figure 6 and Figure 7 A first wiring harness 301 is led out from the flap 3; a second wiring harness 81 is led out from the main box 8, extending downward from the top of the main box 8 along the rear wall of the main box 8 to the bottom; a third wiring harness 15 is led out from the left or right side of the housing 1, the third wiring harness 15 includes three connecting parts, which can also be understood as three sub-wiring harnesses, namely the first connecting part 151, the second connecting part 152 and the third connecting part 153. The first connecting part 151 passes through the partition 11 at the top of the housing 1 and is electrically connected to the second wiring harness 81. The second connecting part 152 extends along the rear bottom of the smoke collection chamber 2 and is electrically connected to the first motor 61. The third connecting part 153 extends along the rear bottom of the smoke collection chamber 2, then extends along the first swing arm assembly 62 to the flap 3 and is electrically connected to the first wiring harness 301, thereby realizing the electrical connection between the various electrical components.

[0050] Therefore, the range hood provided in this embodiment, due to the large size of the overall wiring harness, divides the overall wiring harness into a first wiring harness 301, a second wiring harness 81, and a third wiring harness 15 for separate arrangement and connection in order to ensure safe and convenient assembly. This makes the internal wiring more organized, avoids safety hazards caused by messy wiring, tangling, or interference, improves the wiring safety, and thus improves the electrical safety of the range hood.

[0051] It should be noted that the aforementioned wire harnesses may include power supply wires for supplying power to various electrical components, as well as signal lines for transmitting signals to these components. Connections between wire harnesses are achieved through interlocking terminals, facilitating easy assembly and disassembly.

[0052] like Figure 3 As shown, an electrical box 84 is provided on the top of the main box 8. A main power board (not shown) is provided inside the electrical box 84. The fan mechanism is electrically connected to the main power board inside the electrical box 84 through wires. The wiring harness extending out from the electrical box 84 is the first wiring harness 301.

[0053] Specifically, such as Figure 5 As shown, the first swing arm assembly 62 includes a first swing arm 621 and a second swing arm 622. One end of the first swing arm 621 is connected to the output shaft of the first motor 61, and the other end is hinged to one end of the second swing arm 622. The other end of the second swing arm 622 passes through the through hole 211 and is hinged to the back of the flap 3. When the output shaft of the first motor 61 rotates, the first motor 61 drives the first swing arm 621 to rotate, the first swing arm 621 drives the second swing arm 622 to rotate, and the second swing arm 622 drives the flap 3 to rotate, thus opening or closing. By adopting the above-described swing arm structure, when the flap 3 is closed, the first swing arm 621 and the second swing arm 622 are folded, occupying little space. When the flap 3 is open, the first swing arm 621 and the second swing arm 622 extend to a longer length, thereby opening the flap 3 to a specific angle to meet a larger smoke collection area.

[0054] like Figure 8 As shown, the second swing arm 622 of the first swing arm assembly 62 is covered with a wire housing 63. The wire housing 63 and the second swing arm 622 form a first wiring channel 631. The third connecting part 153 extends through the first wiring channel 631 to the flap 3 and is electrically connected to the first wire harness 301. In this way, the third connecting part 153 can be arranged within the first wiring channel 631 to standardize the routing of the third connecting part 153, protect the wire harness, isolate it from oil fumes, prevent it from being contaminated or corroded, thus contributing to circuit safety. Furthermore, the wire harness is easy to manage, the overall wiring is concealed, and the aesthetics are improved.

[0055] like Figure 9As shown, the flap 3 includes a flap body 31 and a cover 32. The cover 32 is detachably connected to the inside of the flap body 31 and forms an installation cavity. A lighting module 33, a WiFi module, and a control module are installed within the installation cavity. The connecting wires of the lighting module 33, the WiFi module, and the control module constitute a first wiring harness 301. The lighting module 33, the WiFi module, and the control module constitute the electrical components within the flap 3 to meet the different functional requirements of the range hood. For example, the lighting module 33 illuminates the stove and surrounding area, allowing users to clearly see the state of the ingredients, the amount of seasonings, and the position of cooking utensils during cooking, providing convenience and enhancing the user's cooking experience. It also prevents users from suffering burns or cuts due to insufficient light. By placing the lighting module 33 inside the flap 3, it also serves to protect and prevent dust accumulation.

[0056] Specifically, the lighting module 33 includes a snap-fit ​​base and a lampshade. The cover 32 also has mounting holes, with the lampshade extending out of the mounting holes to provide illumination. In this embodiment, two lighting components are used, spaced apart along the length of the cover 32. Each lighting component corresponds to one mounting hole, reducing the number of lighting components while ensuring lighting effect, thus lowering manufacturing costs. Of course, in other embodiments, the number of lighting components can be three, four, five, etc., and this embodiment does not limit this.

[0057] like Figure 6 As shown, an opening 321 is provided on the upper side of the cover 32. The terminals of the first wire harness 301 are exposed at the opening 321 and used for electrical connection with the third connection part 153. The terminals of the first wire harness 301 are exposed at the opening 321 to engage with the terminals of the third connection part 153. The main body of the first wire harness 301 is hidden in the mounting cavity, which can protect the wire harness, isolate it from oil fumes, prevent it from being contaminated or corroded, and contribute to circuit safety. In addition, the wire harness is easy to manage, the overall wiring is concealed, and the aesthetics are improved.

[0058] In an optional embodiment, such as Figure 10As shown, a wiring sleeve 34 is provided on the inner side of the flap body 31. The wiring sleeve 34 extends in the left-right direction. One end of the wiring sleeve 34 connects to the opening 321, and the other end extends to near the first swing arm assembly 62. A second wiring channel is formed between the wiring sleeve 34 and the flap body 31. The third connecting part 153 passes through the second wiring channel and is electrically connected to the first wire harness 301. In this way, after the third connecting part 153 extends out from the first wiring channel 631, it can be directly arranged in the second wiring channel to further standardize the routing of the third connecting part 153, protect the wire harness, isolate oil fumes, prevent contamination or corrosion of the wire harness, contribute to circuit safety, facilitate wire harness management, conceal the overall wiring, and improve aesthetics.

[0059] In an optional embodiment, the cable routing sleeve 34 can be snapped onto the upper side of the cover 32. This facilitates the installation and removal of the cable routing sleeve 34 and improves assembly efficiency.

[0060] In an optional embodiment, combined with Figure 3 and Figure 11 The rear wall of the main box 8 has a cable tray 82 extending vertically. The second wire harness 81 extends through the cable tray 82 to the bottom of the main box 8. A cable cover plate 83 is connected to the rear wall of the main box 8, covering the cable tray 82. In this way, the second wire harness 81 can be arranged in the cable tray 82 to standardize the routing of the second wire harness 81. Secondly, the cable cover plate 83 can protect the second wire harness 81, isolate it from oil fumes, prevent it from being contaminated or corroded, which helps with circuit safety. In addition, the wire harness is easy to manage, the overall wiring is concealed, and the aesthetics are improved.

[0061] In this embodiment, when the smoke collection chamber 2 is opened, it flips outward relative to the housing 1 while simultaneously sliding upward at an angle; conversely, when the smoke collection chamber 2 is closed, it flips inward relative to the housing 1 while simultaneously sliding downward at an angle. In other words, when the smoke collection chamber 2 is open, it not only rotates relative to the housing 1 but also extends the smoke collection area forward through upward sliding, thereby expanding the coverage of the smoke collection area. As the smoke collection chamber 2 extends forward, the flap 3 unfolds and adjusts its angle, further increasing the smoke collection area and effectively improving smoke collection efficiency. This helps prevent oil fumes from escaping and improves the cleanliness and air quality of the kitchen. Simultaneously, the upward sliding of the smoke collection chamber 2 also raises the flap 3 as a whole, preventing obstruction of vision and head bumps.

[0062] In an optional embodiment, such as Figure 4As shown, the driving mechanism also includes a second driving assembly 7, which drives the smoke collection chamber 2 to rotate relative to the housing 1 while also generating a sliding displacement in the tilt direction. Specifically, the second driving assembly 7 includes a rotating component 71, a first guide component 72, and a second guide component 73. The rotating component 71 drives the smoke collection chamber 2 to rotate, and the smoke collection chamber 2 slides in contact with the housing 1 through the first guide component 72 and the second guide component 73.

[0063] The flipping component 71 drives the smoke collection chamber 2 to flip, providing the smoke collection chamber 2 with the power to open or close, causing the smoke collection chamber 2 to extend outward from the housing 1 and reach the smoke extraction position. The smoke collection chamber 2 slides with the housing 1 through the first guide component 72 and the second guide component 73. The first guide component 72 and the second guide component 73 limit the sliding trajectory of the smoke collection chamber 2, ensuring that the smoke collection chamber 2 is stable and does not shake during the sliding process. Through the guidance of the guide components, the smoke collection chamber 2 can flip outward relative to the housing 1 when it is opened, and at the same time generate an outward sliding displacement in the tilt direction. Therefore, the smoke collection area extends forward, the smoke collection area is larger, the smoke collection efficiency is effectively improved, and it helps to prevent the escape of oil fumes and improve the air quality in the kitchen.

[0064] Optionally, such as Figure 12 As shown, the tilting component 71 includes a second motor 711 and a second swing arm assembly 712. The second motor 711 is connected to the housing 1, and one end of the second swing arm assembly 712 is connected to the second motor 711 for transmission, while the other end is connected to the smoke collection chamber 2. Specifically, in conjunction with... Figure 4 and Figure 5 The second swing arm assembly 712 is configured as two, and the flipping component 71 also includes a drive shaft 713. The drive shaft 713 extends in the left and right direction. One end of the drive shaft 713 is fixedly connected to the output shaft of the second motor 711, for example, by welding or screw fixing, and the other end passes through the housing 1 and is rotatably connected to the housing 1. The two sets of second swing arm assemblies 712 are respectively connected to the left and right sides of the smoke collection chamber 2 and are simultaneously fixedly mounted on the drive shaft 713.

[0065] When the output shaft of the second motor 711 rotates, it drives the transmission shaft 713 to rotate. The transmission shaft 713 drives the two sets of second swing arms 712 to rotate synchronously. The two sets of second swing arms 712 cause the smoke collection chamber 2 to flip relative to the housing 1, thus opening or closing it. In this way, the second motor 711 drives the two sets of second swing arms 712 to rotate synchronously through the transmission shaft 713, which ensures that the left and right sides of the smoke collection chamber 2 move synchronously when opening or closing, ensuring the synchronicity and stability of the movement.

[0066] Optionally, such as Figure 4 and Figure 5As shown, the housing 1 also includes an inner side plate 13 and an outer side plate 12 located on the left and right sides. The inner side plate 13 is located inside the outer side plate 12, and the outer side plate 12 encloses and forms a sealed chamber. The second motor 711 is located in one of the sealed chambers and is fixed to the inner side plate 13. By installing the second motor 711 in the sealed chamber, it can isolate oil fumes, minimize direct contact between oil fumes and the second motor 711, and extend the service life of the second motor 711.

[0067] Optionally, an ambient light assembly 16 is also provided in the sealed cavity where the second motor 711 is installed. The connecting wires of the second motor 711 and the ambient light assembly 16 form a third wiring harness 15. The ambient light assembly 16 includes an ambient light body 161 and an ambient light bracket. The ambient light bracket is fixed to the housing 1, and the ambient light body 161 is embedded in the ambient light bracket and protrudes from the outer side panel 12. The ambient light body 161 mainly serves as lighting and decoration, thereby giving the range hood a better ambient lighting effect and improving the overall atmosphere. The ambient light bracket is universal, and users can replace the ambient light body 161 according to their own lighting needs (such as color, brightness, or style).

[0068] Optionally, such as Figure 3 As shown, an ambient light assembly 16 is also installed in the sealed chamber on the side away from the second motor 711 (left side). The partitions 11 on the left and right sides of the main box 8 are respectively provided with first wiring holes 111, and each first wiring hole 111 is connected to the sealed chamber on the corresponding side. Therefore, after the second wiring harness 81 extends to the bottom of the main box 8, it is divided into two parts. One part of the second wiring harness 81 extends to the left and is electrically connected to the ambient light assembly 16 on the left side through the first wiring hole 111 on the left side. The first connecting part 151 of the third wiring harness 15 extends out from the first wiring hole 111 on the right side. The other part of the second wiring harness 81 extends to the right and is electrically connected to the first connecting part 151.

[0069] Optionally, such as Figure 11 As shown, the housing 1 also includes two top plates 14 located on the upper side. The two top plates 14 are located on the left and right sides of the main box 8, respectively. The top plates 14 are fastened to the upper side of the partition 11 and cover the wire harness on the upper side of the partition 11, maintaining an integrated and aesthetically pleasing appearance.

[0070] In an optional embodiment, such as Figure 7As shown, a cable guard box 5 is provided on the rear side of the interior of the housing 1. The connection point between the second connecting part 152 and the terminal of the first motor 61 is located inside the cable guard box 5. Specifically, a second wiring hole 131 is provided at the bottom of the inner side plate 13. The second connecting part 152 of the third wire harness 15 extends out from the second wiring hole 131 at the bottom of the sealed chamber, and then extends to the cable guard box 5 at the bottom rear side of the smoke collection chamber 2. It is electrically connected to the terminal of the first motor 61 inside the cable guard box 5 to protect the terminal connection point, isolate oil fumes, and help ensure circuit safety. The third connecting part 153 extends out from the second wiring hole 131 at the bottom, and also extends to the cable guard box 5 at the bottom rear side of the smoke collection chamber 2. Then it extends out from the through hole on the side of the cable guard box 5, extends to the second swing arm 622 assembly, and is electrically connected to the first wire harness 301 in sequence along the first wiring channel 631 and the second wiring channel. To facilitate the distinction between the first connecting part 151 and the second connecting part 152, as shown... Figure 7 As shown, in this embodiment, dashed lines and solid lines are used to distinguish between the two parts. The dashed lines represent the third connecting portion 153, and the solid lines represent the second connecting portion 152.

[0071] Specifically, such as Figure 12 and Figure 14 As shown, the second swing arm assembly 712 includes a third swing arm 7121, a fourth swing arm 7122, and a swing arm bracket 7123. The third swing arm 7121 is fixedly mounted on the drive shaft 713, for example, by welding or screwing. The fourth swing arm 7122 is hinged to the third swing arm 7121. The swing arm bracket 7123 is hinged to the fourth swing arm 7122 and fixedly connected to the smoke collection chamber 2.

[0072] When the output shaft of the second motor 711 rotates, it drives the transmission shaft 713 to rotate. The transmission shaft 713 then drives the third swing arm 7121 to rotate. The third swing arm 7121 transmits power sequentially through the fourth swing arm 7122 and the swing arm bracket 7123, ultimately driving the smoke collection chamber 2 to move. By adopting the above-mentioned swing arm structure, when the smoke collection chamber 2 is closed, the third swing arm 7121 and the fourth swing arm 7122 fold, occupying little space. When the smoke collection chamber 2 is open, the third swing arm 7121 and the fourth swing arm 7122 extend, thereby opening the smoke collection chamber 2 to a specific angle to meet a larger smoke collection area.

[0073] Optionally, the smoke collection chamber 2 is provided with a first guide component 72 and a second guide component 73 on both the left and right sides to ensure that the smoke collection chamber 2 moves smoothly without shaking during the sliding process.

[0074] Specifically, such as Figure 9As shown, the first guide component 72 is located below the second guide component 73. The first guide component 72 includes a guide bracket 721 and a guide shaft 722. The guide bracket 721 is fixed to the outer side of the inner side plate 13, and the guide shaft 722 is fixed to the side of the smoke collection chamber 2. A guide hole 7211 is provided on the guide bracket 721, and the guide shaft 722 is rotatably connected to the guide hole 7211 and can slide along the guide hole 7211. The second guide component 73 includes a guide rail 732 and a slider 731. The guide rail 732 is fixed to the inner side of the inner side plate 13, and the slider 731 can slide along the guide rail 732. The end of the slider 731 is rotatably connected to the smoke collection chamber 2.

[0075] When the second motor 711 drives the smoke collection chamber 2 to rotate via the second swing arm assembly 712, the smoke collection chamber 2 drives the slider 731 and the guide shaft 722 to move. The slider 731 rotates relative to the smoke collection chamber 2 around the hinge point while sliding along the guide rail 732. The guide shaft 722 rotates in the guide hole 7211 while sliding along the guide hole 7211. Through the coordinated action of the slider 731 and the guide shaft 722, the composite motion path of the entire smoke collection chamber 2 is determined, ensuring that the smoke collection chamber 2 is stable and does not shake during the sliding process.

[0076] Furthermore, such as Figure 3 and Figure 10 As shown, the smoke collection chamber 2 includes a main body 21 and a reinforcing member 23. The reinforcing member 23 is connected to both ends of the main body 21. The guide shaft 722, slider 731, and swing arm bracket 7123 are all connected to the reinforcing member 23. This arrangement strengthens the structural integrity of the top of the main body 21 and prevents deformation. The hinge axes of the swing arm bracket 7123 and the fourth swing arm 7122 are coaxial with the hinge axes of the slider 731 and the reinforcing member 23 to meet the requirements of the motion trajectory.

[0077] like Figure 1 As shown, the smoke collection chamber 2 also includes an oil filter 22. An installation port is provided on the front side of the main body 21 of the smoke collection chamber, and the oil filter 22 covers the installation port. Multiple smoke inlets 221 are provided on the oil filter 22. The fumes produced during cooking contain a large number of grease particles. If the grease enters the fan directly, it will adhere to the motor, blades, and other core components, leading to increased operating resistance, increased noise, and even damage. The oil filter 22, as the first line of defense, filters these oil droplets through dense pores, preventing them from directly entering the range hood or adhering to the fan blades. This reduces the accumulation of grease on internal parts, resulting in cleaner filtered air and effectively reducing grease contamination of the internal ducts of the range hood and the external environment.

[0078] The top of the flap 3 is rotatably connected to the top of the smoke collection chamber 2. This arrangement ensures that when the flap 3 is fully opened, its bottom end opens relative to the smoke collection chamber 2, thereby better absorbing the generated fumes. Optionally, the top of the flap 3 can be rotatably connected to the smoke collection chamber 2 via a hinge, pivot, or swivel; no specific limitation is made here.

[0079] like Figure 1 and Figure 2 As shown, the range hood also includes an oil cup 4, which is detachably connected to the bottom of the housing 1. The vertical projection of the bottom edge of the smoke collection chamber 2 is within the range of the oil cup 4, so that all the oil droplets on the front side of the smoke collection chamber 2 can enter the oil cup 4. When the flap 3 is fully closed, it can cover the front side of the oil cup 4, so that the oil cup 4 is hidden inside the flap 3 and is not easily seen, which not only improves the overall aesthetics, but also facilitates the daily cleaning of the flap 3.

[0080] Optionally, the oil cup 4 is installed at the bottom of the housing 1 by a pull-out mechanism, which allows for easy disassembly and cleaning of the oil cup 4. The pull-out mechanism of the oil cup 4 is existing technology and will not be described in detail here.

[0081] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
