Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a range hood. Background Technology

[0002] As an indispensable appliance in modern kitchens, range hoods primarily function to remove cooking fumes, odors, and harmful gases generated during cooking through a fan system, thereby maintaining fresh kitchen air and enhancing the user experience. To meet the demands for aesthetics and ease of cleaning, an increasing number of range hood products incorporate glass panels as part of their exterior decoration and smoke collection area, which places higher demands on the installation structure of these glass panels.

[0003] In existing technologies, range hood glass panels are mostly fixed using screws or direct embedded installation. While screw fastening provides a certain degree of stability, it suffers from complex installation and inconvenient disassembly. Users often need to use specialized tools for routine maintenance or glass replacement, making the process cumbersome and affecting ease of use. Direct embedded installation, on the other hand, typically relies on a single plug-in structure or elastic clips, which are prone to loosening or even falling off over long-term use, posing a safety hazard.

[0004] Furthermore, traditional fixed glass structures lack effective positioning and locking mechanisms when connected to the range hood's outer casing, resulting in low overall structural strength and poor vibration resistance. This is especially true in side-draft or high-volume range hoods, where significant airflow disturbances and mechanical vibrations during operation make the glass panel more prone to displacement or wobbling, affecting product lifespan and safety performance.

The housing assembly is provided with a through hole corresponding to the housing assembly fixing part, and the housing assembly fixing part passes through the through hole and connects to the housing assembly.

[0007] Furthermore, the glass plate is inverted U-shaped, and the fixing plate includes a left fixing plate, a middle fixing plate and a right fixing plate. The middle fixing plate is connected to the middle back of the glass plate, and the left fixing plate and the right fixing plate are respectively connected to the back of the left edge and the back of the right edge of the glass plate. The left fixing plate, the middle fixing plate and the right fixing plate are all provided with the horizontal buckle. The outer shell assembly includes a main frame and a crossbeam. The main frame has an opening on the front, and the crossbeam is horizontally disposed at the opening and connected to the left and right sides of the main frame.

[0011] Furthermore, the top edge of the central fixing plate extends outward with a protrusion, which bends toward the back side of the central fixing plate to form a flange, and the outer shell assembly fixing part is disposed at the free end of the flange.

[0012] Furthermore, the flange includes a connecting flange and an mounting flange that are interconnected; One end of the connecting flange is perpendicularly connected to the central fixing plate, and the other end is connected to the mounting flange; The mounting flange is bent away from the center of the central fixing plate relative to the connecting flange, and the outer shell assembly fixing part is disposed on the mounting flange.

The above diagram is only for illustrating the structural relationships related to the invention and is not intended as a scale representation of the actual product.

[0023] like Figures 1 to 6As shown in the figure, an embodiment of the present invention provides a range hood, which includes a glass panel assembly and a housing assembly 11. The glass panel assembly includes a glass panel 10 and a fixing plate. The front side of the fixing plate is firmly bonded to the back side of the glass panel 10 by a high-strength transparent adhesive layer or structural adhesive, ensuring the stability and sealing of the connection without affecting the aesthetics and transparency of the glass panel 10. The fixing plate is formed by stamping metal sheet, preferably stainless steel or aluminum alloy, which has good strength, corrosion resistance and processing performance. Multiple horizontal buckles 4 are provided on the back side of the fixing plate. The horizontal buckles 4 extend horizontally and are used to realize a detachable sliding connection with the housing assembly 11. Multiple positioning parts 9 are provided on the housing assembly 11 corresponding to the positions of the multiple horizontal buckles 4. The positioning parts 9 are slot structures opened on the side wall or crossbeam of the housing assembly 11. Their shape matches the horizontal buckles 4, allowing the horizontal buckles 4 to slide in or out in the left and right directions, thereby realizing the quick installation and disassembly of the glass panel assembly and the housing assembly 11, which greatly facilitates the assembly, maintenance and cleaning of the whole machine.

[0024] A housing assembly fixing part 5 is also provided in the middle of the fixing plate. The fixing part 5 is a structure that extends upward or downward from the middle of the fixing plate. There can be one or more of them, preferably two symmetrically arranged to improve the connection stability. A through hole is provided on the housing assembly 11 corresponding to the position of the housing assembly fixing part 5. The through hole is a through hole structure, and its inner diameter is slightly larger than the outer diameter of the housing assembly fixing part 5 to facilitate the smooth passage of the housing assembly fixing part 5. In this embodiment, after the housing assembly fixing part 5 passes through the through hole, it is further fixedly connected to the housing assembly 11 by fasteners such as screws, bolts or snap rings. This provides additional longitudinal restraint force on the basis of the initial positioning completed by the transverse buckle 4, preventing the glass plate assembly from shaking back and forth or falling off during use, and significantly improving the structural stability and safety of the whole machine.

[0025] In this embodiment, the glass panel 10 has an inverted U-shaped structure, with an arc or flat top transitioning downwards and both sides extending vertically downwards. This design not only has modern aesthetic features but also effectively guides the oil fumes upwards, reducing dead airflow angles. The inverted U-shaped glass panel 10 is made of high-strength tempered glass, possessing excellent impact resistance, high-temperature resistance, and good light transmittance, making it easy for users to observe the internal working status.

[0026] The fixing plates include a left fixing plate 1, a middle fixing plate 2, and a right fixing plate 3, which are respectively connected to the back of the left edge, the back of the middle area, and the back of the right edge of the glass plate 10. Specifically, the middle fixing plate 2 is fixed to the back of the center of the glass plate 10 by structural adhesive or spot welding, mainly used to bear the main structural load and realize the core connection with the outer shell assembly 11; the left fixing plate 1 and the right fixing plate 3 are located on the back of the left and right edges of the glass plate 10, respectively, for auxiliary support and participation in overall positioning. Each of the left fixing plate 1, the middle fixing plate 2, and the right fixing plate 3 is provided with at least one transverse buckle 4, preferably two transverse buckles 4 for each fixing plate to enhance the reliability of the connection.

[0027] The outer casing assembly 11 includes a main frame and a crossbeam. The main frame is enclosed by left and right side frames, a top frame, and a bottom frame, forming a hollow box structure. The interior houses core components such as the fan system, smoke collection chamber, oil guiding structure, and electrical control system. The front of the main frame is open to facilitate the installation and removal of the glass panel assembly. The crossbeam is horizontally positioned in the center of the front opening of the main frame and is fixedly connected to the left and right side frames, serving to enhance structural rigidity and separate the smoke inlet area.

[0028] At least one positioning part 9 is provided on the crossbeam for sliding engagement with the transverse latch 4 on the central fixing plate 2; at least one positioning part 9 is provided on the left side frame of the main frame, corresponding to the transverse latch 4 on the left fixing plate 1; similarly, a positioning part 9 is also provided on the right side frame, corresponding to the transverse latch 4 on the right fixing plate 3. During assembly, the operator pushes the glass plate assembly into the front opening of the outer casing assembly 11 from the front, aligning each transverse latch 4 with the corresponding positioning part 9, and then pushes the glass plate assembly horizontally (left-right direction) to slide the transverse latch 4 into the positioning part 9 until it is fully engaged, forming a secure connection. Disassembly is the opposite; simply slide in the opposite direction to release the connection. This can be done without tools, greatly improving maintenance convenience.

[0029] The upper and lower parts of the main frame are set at a certain angle, for example, the upper part tilts backward and the lower part is relatively vertical, forming an "eight" or trapezoidal outline. This asymmetrical structure helps to optimize airflow organization and improve the efficiency of fume extraction. The horizontal beam is set at the angle transition position of the front opening, that is, at the intersection of the upper and lower parts. It not only serves as a structural connection, but also as a boundary defining structure for the upper smoke inlet.

[0030] The bottom edge of the glass plate 10 is recessed inward, forming an arc-shaped or right-angled concave area. This area, together with the bottom of the main frame, forms a lower smoke inlet to capture cooking fumes diffusing from below the stove. Simultaneously, a gap is maintained between the top edge of the glass plate 10 and the top of the main frame, forming an upper smoke inlet to absorb rising cooking fumes. By setting up both upper and lower smoke inlets, a three-dimensional air intake structure is achieved, effectively expanding the fume absorption coverage and improving smoke removal efficiency, making it particularly suitable for open kitchens or high-power cooking scenarios.

[0031] In addition, the lower smoke inlet has a larger air intake area than the upper smoke inlet to accommodate the physical law that cooking fumes mainly rise from below; while the upper smoke inlet serves as an auxiliary air intake, specifically designed to capture fine oil mist particles carried by the high-temperature hot airflow and prevent them from escaping into the indoor space. A removable baffle can also be installed at the lower smoke inlet to adjust the air intake angle.

[0032] To prevent foreign objects from entering the range hood and improve safety, an oil filter is installed over the top smoke inlet. Made of woven stainless steel wire, the filter effectively intercepts larger oil droplets and splatter without obstructing airflow. The filter is removably installed around the top smoke inlet using a snap-on or magnetic method for easy regular cleaning.

[0033] Specifically, the top of the crossbeam bends inward and upward to form an upper bend 8, which has an L-shaped or arc-shaped structure and is located inside the oil filter, i.e., on the side facing the inside of the range hood. This upper bend 8 not only enhances the structural strength of the crossbeam but also guides airflow and reduces vortex losses. More importantly, the through hole is located in the area below the upper bend 8, i.e., in the transition section between the upper bend 8 and the main structure below it, allowing the outer casing assembly fixing part 5 to pass through smoothly and connect with the upper bend 8.

[0034] The top of the central fixing plate 2 is provided with a housing assembly fixing part 5. This housing assembly fixing part 5 is preferably a threaded metal sheet or column, which passes through a through hole and is locked to the back of the upper bent part 8 by a nut or self-locking nut. In another embodiment, the housing assembly fixing part 5 can also be a columnar structure with a slot, which, together with the elastic buckle on the housing assembly 11, enables a quick-release connection. This dual connection mechanism—that is, the horizontal buckle 4 provides horizontal positioning, and the housing assembly fixing part 5 provides vertical locking—ensures both ease of installation and long-term reliability.

[0035] A sealing gasket can also be added to the inside of the upper bend 8 to prevent oil fumes from leaking through the through hole; or a shock-absorbing rubber sleeve can be installed between the housing assembly fixing part 5 and the through hole to reduce vibration transmission during fan operation and improve the overall noise reduction performance. In addition, an oil guide groove can be set at the edge of the oil screen to guide the intercepted oil droplets to the oil collection system on both sides, preventing them from dripping and contaminating the surface of the glass plate 10.

[0036] In one embodiment, the lateral sliding buckle 4 includes a connecting part 41 and a locking part 42; one end of the connecting part 41 is connected to the left fixing plate 1, the middle fixing plate 2 or the right fixing plate 3 respectively; one end of the locking part 42 is connected to the other end of the connecting part 41, and the locking part 42 extends laterally.

[0037] One end of the connecting part 41 is fixedly connected to the left fixing plate 1, the middle fixing plate 2, or the right fixing plate 3. Specifically, this can be achieved through integral molding, welding, riveting, or screw fixing. The connecting part 41 serves to support and connect the snap-fit ​​part 42, and is the basic part of the entire snap-fit ​​structure.

[0038] One end of the latching part 42 is connected to the other end of the connecting part 41, and the entire part extends in the lateral direction (i.e., it extends perpendicularly to the surface of the fixing plate and then turns to the horizontal direction). The latching part 42 is designed to facilitate insertion and sliding locking, such as with a limiting protrusion or a beveled guide structure. In this embodiment, the lateral sliding buckle 4 has an overall L-shaped structure, in which the connecting part 41 is a vertical section and the latching part 42 is a horizontal section.

[0039] The L-shaped horizontal sliding buckle 4-structure allows for installation without the need for screws or other auxiliary tools; a secure connection is achieved in just two steps: insertion and sliding, significantly improving assembly efficiency. The L-shaped structure has good stress distribution and can withstand certain pulling and shearing forces; the horizontal sliding locking mechanism is more stable and reliable than traditional plug-in connections, preventing detachment due to vibration.

[0040] In one embodiment, the top edge of the central fixing plate 2 extends outward with a protrusion, which bends towards the back side of the central fixing plate 2 to form a flange 6, on which the outer casing assembly fixing part 5 is disposed. Specifically, the flange 6 includes a connecting flange 61 and a mounting flange 62 connected to each other; one end of the connecting flange 61 is perpendicularly connected to the central fixing plate 2, and the other end is connected to the mounting flange 62; the mounting flange 62 bends away from the center of the central fixing plate 2 relative to the connecting flange 61, and the outer casing assembly fixing part 5 is disposed on the mounting flange 62. The included angle between the connecting flange 61 and the mounting flange 62 is 30° to 70°, and is measured with the connecting flange 61 as a reference.

[0041] One end of the connecting flange 61 is perpendicularly connected to the central fixing plate 2. It acts as a bridge, connecting the mounting flange 62 to the central fixing plate 2. This can be achieved through integral molding, welding, riveting, or screw fixing. The material can be metal or plastic, selected according to the overall structural strength requirements.

[0042] One end of the mounting flange 62 is connected to the other end of the connecting flange 61. The entire assembly extends upward away from the central fixing plate 2 (i.e., upward and backward). A housing assembly fixing part 5 is provided on its surface for mating with the mounting position on the range hood housing assembly.

[0043] An angle is formed between the connecting flange 61 and the mounting flange 62, ranging from 30° to 70°, measured with the connecting flange 61 as the reference. This angle design helps to improve structural strength and accommodate the installation space layout of different housing components.

[0044] When the horizontal sliding buckle 4 aligns with the corresponding insertion hole or slot on the housing assembly, the flange 6 extending outward from the bottom of the central fixing plate 2 also accurately aligns with the pre-drilled hole on the housing assembly. When the horizontal sliding buckle 4 slides into the locking position and engages with the limiting groove or latch in the housing assembly, the housing assembly fixing part 5 matches the corresponding hole on the housing assembly, and then the mounting flange 62 is fixedly connected to the housing assembly by fasteners.

[0045] In one embodiment, the central fixing plate 2 includes a mounting plate 21 and an air guide plate 22 connected to each other at a predetermined angle. The mounting plate 21 is a vertical or nearly vertical flat plate structure with a flat surface, used for large-area bonding and fixing to the back of the glass plate 10. This connection method can use high-strength structural adhesive (such as silicone sealant or epoxy resin adhesive) for full-coverage bonding, supplemented by local spot welding or riveting processes, to ensure that the glass plate 10 and the mounting plate 21 have sufficient bonding strength to withstand vibration, thermal expansion and contraction, and external impact during daily use.

[0046] The air guide plate 22 extends downwards and backwards from the lower edge of the mounting plate 21, forming an inclined or curved surface. Its inclination angle is preferably between 15° and 35°, creating a gradually downward-shifting trend relative to the horizontal plane. The end of the air guide plate 22 extends into the interior area of ​​the lower smoke inlet, reaching the entrance of the smoke collection chamber, thus actively guiding the flow of fumes. When fumes generated during cooking rise from the stovetop, they first contact the surface of the glass plate 10 and move upwards along its inner wall. Upon reaching the area where the air guide plate 22 is located, the airflow is forced to change direction due to the backward-sloping structure of the air guide plate 22, converging towards the air intake of the fan system. This effectively reduces eddies and backflow, improving overall air intake efficiency.

[0047] Mounting plate 21 and air guide plate 22 are integrally formed structures, made from the same piece of metal sheet through bending and stamping processes. Galvanized steel or stainless steel sheet is preferred, as it possesses good rigidity and corrosion resistance. A clear transition line is formed at the connection point between the two, constituting a structural "step." This step not only enhances the overall structural strength of the central fixing plate 2 but also serves a positioning and limiting function.

[0048] The bottom edge of the glass plate 10 precisely abuts against the upper surface of the step, i.e., the support surface formed by the intersection of the mounting plate 21 and the air guide plate 22. This design achieves precise vertical positioning of the glass plate 10, preventing vertical displacement or misalignment during assembly. Simultaneously, the step bears part of the weight of the glass plate 10, reducing the long-term stress load on the adhesive layer and extending the connection life. Furthermore, rubber gaskets or elastic sealing strips can be installed at the step to enhance sealing, prevent oil and air leakage, and provide cushioning and shock absorption.

[0049] Regarding the stepped structure formed between the mounting plate 21 and the air guide plate 22, as mentioned above, the step is formed by the bottom edge of the mounting plate 21 and the front edge of the air guide plate 22, forming a horizontally extending planar platform that is sufficient to provide a stable support surface.

[0050] During actual assembly, the bottom edge of the glass plate 10 is completely flush with the step. This step serves not only as a mechanical support structure but also as a critical assembly reference surface, ensuring the installation consistency of the glass plate 10 in the height direction.

[0051] More importantly, this stepped structure provides ideal space for sealing design. A ring-shaped sealing strip or liquid sealant (such as high-temperature resistant silicone) can be pre-laid on the step surface. When the glass plate 10 is pressed into place, the sealing material is evenly expanded under pressure, filling the tiny gap between the bottom edge of the glass plate 10 and the step, forming a complete oil and smoke-proof sealing barrier. This sealing structure effectively prevents oil fumes from escaping from the gaps at the bottom of the glass plate 10, avoiding pollution of the external environment or affecting the user experience.

[0052] In addition, an oil guiding channel can be provided on the rear side of the step (i.e., one side of the air guide plate 22) to guide the condensed oil droplets to the oil collection grooves on both sides, preventing oil from accumulating on the surface of the air guide plate 22 and dripping. This oil guiding channel can be a groove formed by mold, or it can be achieved by adding an oil guiding strip.

For example, "connect" can mean a fixed connection, a detachable connection, or an integral connection.
