[0025] With the continuous development of science and technology, range hoods have become one of the most common kitchen appliances in people's daily lives. In the existing technology, in order to improve the smoke collection effect of range hoods, a hinged plate is usually set on the range hood. However, in order to realize the opening and closing of the hinged plate and the baffle plate, a complex connection structure is usually required, which is costly and unreliable.
[0026] Typically, after a range hood is installed, the front end of the hood housing is the end closest to the user, and the rear end is positioned opposite the front end. The frame is located on top of the housing. It should be noted that, in this application, the front end or front side of a component or assembly refers to the end or side of the component or assembly closest to the user; the rear end or rear side of a component or assembly refers to the end or side of the component or assembly away from the user and opposite to the aforementioned front end or front side. For example, the rear side of the range hood housing is usually located close to the wall mounting surface. This application uses the state of the range hood after installation as an example for description.
[0027] This application first proposes a range hood, such as Figures 1 to 14 As shown. Figure 1 This is a schematic diagram of the structure of one embodiment of the range hood in the off state according to this application; Figure 2 This is a schematic diagram of the structure of one embodiment of the range hood in its unfolded state according to this application; Figure 3 This is a disassembled structural diagram of some mechanisms of the range hood in the unfolded state of this application; Figure 4 This is a cross-sectional structural schematic diagram of an embodiment of the range hood in its unfolded state according to this application; Figure 5 This is a cross-sectional structural schematic diagram of an embodiment of the range hood in the off state according to this application; Figure 6 yes Figure 4 A structural diagram of part of the embodiment; Figure 7 yes Figure 5 A schematic diagram of the structure of a portion of the embodiment; Figure 8 This is another cross-sectional structural schematic diagram of an embodiment of the range hood in the unfolded state of this application; Figure 9 This is another cross-sectional structural schematic diagram of an embodiment of the range hood in the off state according to this application; Figure 10 yes Figure 8 Side view of the embodiment; Figure 11 yes Figure 10 An enlarged structural diagram of region A in the embodiment; Figure 12 yes Figure 9 Side view of the embodiment; Figure 13 yes Figure 12 An enlarged structural diagram of region B in the embodiment; Figure 14This application presents an exploded structural diagram of an embodiment of the side panel and slide rail. The range hood includes a housing 10, an opening and closing plate 20, and a guide plate 30. The opening and closing plate 20 is rotatably connected to the housing 10. The first end 31 of the guide plate 30 is slidably disposed with the opening and closing plate 20, and the second end 32 disposed opposite to the first end 31 is rotatably disposed with the housing 10. The guide plate 30 and the housing 10 form a guide cavity 110, and the opening and closing plate 20 is disposed on the side of the guide plate 30 away from the guide cavity 110. The opening and closing plate 20 rotates relative to the housing 10 to drive the guide plate 30 to rotate relative to the housing 10, thereby causing the guide plate 30 to enter the unfolded state or the closed state synchronously with the opening and closing plate 20.
[0028] Figure 1 This diagram shows the structure of a range hood with the baffle plate 30 and the opening / closing plate 20 in the closed state. Figure 2 A schematic diagram of the range hood with the baffle 30 and the opening / closing plate 20 in the unfolded state is shown. Specifically, the baffle 30 and the housing 10 together form the baffle cavity 110.
[0029] See Figure 4 , Figure 5 or Figure 8 , Figure 9 During the unfolding process, the rotation of the opening and closing plate 20 causes the guide plate 30 to rotate in the direction away from the guide cavity 110 until it reaches the unfolded state. In the unfolded state, the opening and closing plate 20 forms a smoke-gathering structure, and the unfolded state of the guide plate 30 expands the volume of the guide cavity 110, allowing the oil fume airflow to enter the guide cavity 110 through the air inlet of the range hood, for example, the air inlet can be located on the guide plate 30. During the closing process, the guide plate 30 can rotate with the opening and closing plate 20 in the direction closer to the guide cavity 110 until it reaches the closed state, thus reducing the volume of the guide cavity 110, reducing the overall size of the range hood, and saving space.
[0030] When the range hood needs to extract cooking fumes, the opening and closing plate 20 can be controlled to open and deploy the guide plate 30. Specifically, the first end 31 of the guide plate 30 is slidably disposed with the opening and closing plate 20, that is, the first end 31 and the opening and closing plate 20 are linked. When the opening and closing plate 20 rotates, it can drive the first end 31 of the guide plate 30 to slide relative to the opening and closing plate 20. Furthermore, the second end 32 of the guide plate 30 is rotatably disposed with respect to the housing 10. Therefore, the first end 31 of the guide plate 30 can rotate relative to the second end 32. For example, when the size of the guide plate 30 remains unchanged, the first end 31 of the guide plate 30 performs a circular motion relative to the second end 32.
[0031] In one application scenario, the opening / closing plate 20 is equipped with a slide rail 40, and the first end 31 of the guide plate 30 can slide within the slide rail 40 to achieve relative sliding with the opening / closing plate 20. When the opening / closing plate 20 is opened from the closed state, the opening / closing plate 20 rotates relative to the housing 10, causing the slide rail 40 on the opening / closing plate 20 to rotate along with the opening / closing plate 20. This causes the first end 31 of the guide plate 30 to move on the slide rail 40, thereby sliding relative to the opening / closing plate 20; furthermore, the first end 31 of the guide plate 30 rotates relative to the second end 32. Therefore, the guide plate 30 can enter the opened state as the opening / closing plate 20 rotates, and it can also enter the closed state as the opening / closing plate 20 rotates.
[0032] The beneficial effect of the above-mentioned configuration is that the opening and closing plate 20 of the range hood is located on the side of the guide plate 30 away from the guide cavity 110. When it is open, it can achieve the effect of collecting smoke, and when it is closed, it can reduce the size of the whole machine. The opening and closing plate 20 is rotatably connected to the housing 10. The first end 31 of the guide plate 30 is slidably set with the opening and closing plate 20, and the second end 32 is rotatably set with the housing 10. The opening and closing plate 20 can drive the guide plate 30 to rotate relative to the housing 10 to realize opening and closing. The structure is simple, which can reduce costs and improve the reliability of the range hood.
[0033] Furthermore, this structure allows for the manual unfolding and closing of the opening and closing plate 20 and the guide plate 30 without the need for an external motor drive, resulting in low operating costs, fewer parts, and high reliability.
[0034] In some embodiments, the range hood further includes a frame 60 connected to the housing 10 and disposed above the housing 10.
[0035] In some embodiments, see Figure 8 , Figure 10 , Figure 11 A slide rail 40 is provided on the opening and closing plate 20. The opening and closing plate 20 rotates towards the side away from the guide cavity 110 until the first end 31 rotates with the opening and closing plate 20 to the first point 41 of the slide rail 40. The rotation direction a of the first end 31 is perpendicular to the rotation direction b of the opening and closing plate 20.
[0036] It should be noted that the first end 31 of the guide plate 30 rotates relative to the second end 32 of the guide plate 30, and the opening and closing plate 20 is rotatably connected to the housing 10. Therefore, the movable end of the opening and closing plate 20 rotates relative to the end connected to the housing 10. The opening and closing plate 20 and the guide plate 30 are linked by a slide rail 40. When the first end 31 is at the first position 41, the opening and closing plate 20 and the guide plate 30 are in the unfolded state.
[0037] The above-mentioned configuration can improve the structural stability of the opening and closing plate 20 and the guide plate 30 of the range hood in the unfolded state. For example, in one application scenario, the user can manually open the opening and closing plate 20 to drive the guide plate 30 to rotate away from the guide cavity 110 until the first end 31 of the guide plate 30 slides to the first point 41 of the slide rail 40. At this time, the rotation direction a of the first end 31 is perpendicular to the rotation direction b of the opening and closing plate 20. By continuing to pull the opening and closing plate 20 away from the guide cavity 110, it is difficult to continue to drive the guide plate 30 to rotate. Therefore, the relative positions of the guide plate 30, the opening and closing plate 20, and the housing 10 can be stabilized, and the opening and closing plate 20 and the guide plate 30 of the range hood enter the unfolded state.
[0038] In some embodiments, the slide rail 40 is a linear slide rail 40, and the extension direction of the slide rail 40 is perpendicular to the rotation direction b of the opening and closing plate 20; at the first point 41, the rotation direction a of the first end 31 is perpendicular to the rotation direction b of the opening and closing plate 20.
[0039] This structure is simple and can provide a stable force to the first end 31 of the guide plate 30, making it easier to drive the guide plate 30 to rotate through the opening and closing plate 20. For example, in the unfolded state, with the first end 31 at the first point 41 on the slide rail 40, when the opening and closing plate 20 is pulled further away from the guide cavity 110, since the extension direction of the slide rail 40 is perpendicular to the rotation direction b of the opening and closing plate 20, the direction of the force provided by the slide rail 40 to the first end 31 of the guide plate 30 is parallel to the rotation direction b of the opening and closing plate 20 and perpendicular to the rotation direction a of the first end 31. Therefore, the opening and closing plate 20 cannot drive the guide plate 30 to rotate through the slide rail 40. In the unfolded state, with the first end 31 at the first point 41 on the slide rail 40, when the opening and closing plate 20 is pushed in the opposite direction toward the guide cavity 110, since the extension direction of the slide rail 40 is perpendicular to the rotation direction b of the opening and closing plate 20, the problem of the direction of the force provided by the slide rail 40 to the first end 31 of the guide plate 30 being perpendicular to the rotation direction a of the first end 31 still exists. Therefore, the guide plate 30 cannot be driven to rotate through the slide rail 40. Therefore, in this way, the opening and closing plate 20 and the guide plate 30 can be locked in the deployed state, thus further improving the structural stability of the guide plate 30 and the opening and closing plate 20 in the deployed state.
[0040] In one application scenario, after the opening / closing plate 20 drives the guide plate 30 to rotate away from the guide cavity 110 to the unfolded state, the guide plate 30 can be manually or electrically driven to rotate towards the guide cavity 110. This allows the first end 31 of the guide plate 30 to slide in the opposite direction on the slide rail 40, passing the first point 41, and driving the opening / closing plate 20 to rotate in the opposite direction towards the guide cavity 110. Therefore, the opening / closing plate 20 and the guide plate 30 can be disengaged from the locked position, thus releasing the unfolded state. After disengaging, the opening / closing plate 20 can be manually pushed towards the guide cavity 110, causing it to drive the guide plate 30 to continue rotating in the same direction until it enters the closed state. This design is simple, convenient for manual operation, reduces costs, and improves reliability.
[0041] In some embodiments, when the opening and closing plate 20 and the guide plate 30 are in an intermediate state, the rotation direction a of the first end 31 and the rotation direction b of the opening and closing plate 20 are set at an acute angle.
[0042] It should be noted that the intermediate state refers to the transition from the unfolded state to the closed state of the opening and closing plate 20 and the guide plate 30, or the transition from the closed state to the unfolded state of the opening and closing plate 20 and the guide plate 30. In the intermediate state, the position of the first end 31 on the slide rail 40 is between the first point 41 and the starting point. At this time, the direction of the force exerted by the slide rail 40 on the first end 31 is not perpendicular to the rotation direction 'a' of the first end 31, but rather at a certain angle, so that the opening and closing plate 20 can drive the guide plate 30 to rotate, avoiding direct locking or jamming.
[0043] In some embodiments, the first point 41 is the first end of the slide rail 40.
[0044] The above configuration can further improve the structural stability of the opening and closing plate 20 and the guide plate 30 in the deployed state. The first point 41 is the first end of the slide rail 40, that is, in the deployed state, the first end 31 of the guide plate 30 is located at the first end of the slide rail 40, which can further improve the positional stability of the first end 31 of the guide plate 30 at the first point 41.
[0045] In some embodiments, see Figure 9 , Figure 12 , Figure 13 In the closed state, the first included angle θ between the rotation direction a of the first end 31 and the rotation direction b of the opening and closing plate 20 is ≤30°.
[0046] For example, the first included angle θ can be 5°, 8°, 10°, 15°, 18°, 20°, 25°, 28°, or 30°. The smaller the first included angle θ, the greater the degree of folding of the opening and closing plate 20 and the guide plate 30 in the closed state; the larger the first included angle θ, the easier it is to unfold the opening and closing plate 20 and the guide plate 30, improving ease of use. In some application scenarios, setting the first included angle θ to be less than or equal to 30° can ensure both a compact structure and operational flexibility, optimizing the user experience.
[0047] In some embodiments, the first included angle θ is 5°.
[0048] The above settings can further reduce the overall size of the range hood when it is closed. When closed, the smaller the first included angle θ, the greater the degree of folding of the opening and closing plate 20 and the guide plate 30, the smaller the space occupied by the whole unit, which facilitates the utilization of kitchen space.
[0049] In some embodiments, a slide rail 40 is provided on the opening and closing plate 20, and the range hood also includes a side plate 50. A guide plate 30 is fixedly connected to the side plate 50. A first end 31 is provided near the third end 51 of the side plate 50, and a second end 32 is provided near the fourth end 52 of the side plate 50. The first end 31 is slidably disposed with the slide rail 40 through the third end 51, and the second end 32 is rotatably disposed with the housing 10 through the fourth end 52.
[0050] Specifically, see Figures 3 to 7 Among them, see reference Figure 4 , Figure 5 The deflector 30 is fixedly connected to the side plate 50; see reference. Figure 3 The first end 31 of the deflector 30 is positioned near the third end 51 of the side plate 50, and the second end 32 is positioned near the fourth end 52 of the side plate 50; see reference. Figure 6 , Figure 7 , Figure 6 yes Figure 4 A structural diagram of part of the embodiment; Figure 7 yes Figure 5 A schematic diagram of part of the structure in the embodiment. Figure 6 , Figure 7 The deflector is not shown. Figure 6 The connection relationship between the side plate 50, the hinge plate 20, and the slide rail 40 in the unfolded state is shown. Figure 7 The connection relationship of the side plate 50, the opening and closing plate 20, and the slide rail 40 is shown in the closed state.
[0051] Specifically, the opening and closing plate 20 is slidably connected to the guide plate 30 through the side plate 50 and the slide rail 40. The housing 10 is rotatably set with the guide plate 30 through the side plate 50. The side plate 50 can play a supporting and connecting role. This not only simplifies the structure of the guide plate 30, but also facilitates the installation of the guide plate 30 and improves the overall aesthetics of the range hood.
[0052] In some embodiments, see Figure 3 The range hood includes two side plates 50, which are respectively set on both sides of the baffle plate 30 and fixedly connected to the baffle plate 30.
[0053] The side plate 50 can serve as a support and connection. The side plate 50 is set on both sides of the guide plate 30 to further improve the connection stability between the guide plate 30 and the housing 10 and the opening and closing plate 20, and reduce shaking and noise during use.
[0054] In one application scenario, the range hood includes two side plates 50, which are respectively set on both sides of the guide plate 30, and two slide rails 40 are set on the opening and closing plate 20. The third ends 51 of the two side plates 50 are respectively set close to the two sides of the first end 31 of the guide plate 30, and the third ends 51 of the two side plates 50 are respectively slidably connected to the two slide rails 40 to realize the linkage between the opening and closing plate 20 and the guide plate 30. The fourth ends 52 of the two side plates 50 are respectively set close to the two sides of the second end 32 of the guide plate 30, and are rotatably connected to the housing 10. The second end 32 of the guide plate 30 can be rotatably connected to the housing 10 through the fourth ends 52 of the side plates 50.
[0055] In some embodiments, in the unfolded state, the two side plates 50, the guide plate 30, the housing 10, and the opening and closing plate 20 together form a guide cavity 110. An air inlet may be provided on the guide plate 30 to facilitate the extraction of cooking fumes by the range hood.
[0056] In some embodiments, see Figure 13 , Figure 14 The slide rail 40 includes a sliding groove 410 and limiting plugs 42 disposed at both ends of the sliding groove 410; the third end 51 is provided with a hollow rivet 43, which is disposed in the sliding groove 410 and slidably connected to the sliding groove 410; the hollow rivet 43 is also connected to the side plate 50.
[0057] The limiting plugs 42 at both ends prevent the hollow rivets 43 from sliding out of the sliding groove 410, ensuring stable linkage between the guide plate 30 and the opening and closing plate 20, and improving the reliability and service life of the overall structure. The hollow rivet 43 structure facilitates flexible connection between the sliding groove 410 and the side plate 50, simplifies the installation process, and improves maintenance convenience.
[0058] In some embodiments, the third end 51 is further provided with a roller 44, and one end of the hollow rivet 43 is disposed in the roller 44; the roller 44 is disposed in the sliding groove 410 and is slidably connected to the sliding groove 410.
[0059] Hollow rivets 43 are set inside rollers 44. Through the contact between rollers 44 and sliding grooves 410, the friction between hollow rivets 43 and sliding grooves 410 can be reduced, thereby improving the smoothness of the slide of guide plate 30.
[0060] In some embodiments, the inner diameter of the opening of the sliding groove 410 is smaller than the inner diameter of the bottom of the sliding groove 410, and the roller 44 has a stepped structure, with the outer diameter of the roller 44 near the bottom of the groove being larger than the outer diameter of the roller 44 near the opening. This structure can effectively prevent the roller 44 from sliding out of the groove opening and ensure sliding stability.
[0061] In some embodiments, the roller 44 is a rubber roller 44, which can further reduce friction, reduce wobbling during sliding, and improve sliding smoothness.
[0062] In other embodiments, the hollow rivet 43 is directly disposed on the guide plate 30, and the guide plate 30 is slidably connected to the slide rail 40 through the hollow rivet 43.
[0063] In some embodiments, see Figure 9 , Figure 10 The housing 10 forms a receiving cavity and a first opening communicating with the receiving cavity. In the closed state, the opening and closing plate 20 covers the first opening, and the guide plate 30 is set inside the receiving cavity.
[0064] In the closed state, the opening and closing plate 20 covers the first opening, and the guide plate 30 is set in the accommodating cavity, which can form a sealed space. This not only reduces the overall size of the machine, but also improves its aesthetics. It also reduces the interference of the external environment on the guide plate 30 and other internal components of the range hood, and can play a dustproof role, extending the service life of the range hood.
[0065] In some embodiments, the first opening is provided on the front wall 11 of the housing. In the closed state, the opening and closing plate 20 covers the first opening and is in the same plane as the front wall 11 of the housing.
[0066] This structure allows for a cleaner appearance of the range hood and reduces its space occupation. In one application scenario, the hinged panel 20 can be seamlessly fitted with the front wall 11 of the housing, ensuring overall aesthetics and sealing, while also facilitating user cleaning and maintenance and enhancing the user experience.
[0067] In some embodiments, the hinged panel 20 is a glass panel structure. The smooth surface of the glass panel is easy to wipe, which not only enhances the overall visual effect but also reduces the difficulty of cleaning and improves the user experience.
[0068] In some embodiments, the front wall 11 of the enclosure is a glass panel structure. This design not only enhances the overall visual appeal but also reduces cleaning difficulty and improves the user experience.
[0069] In some embodiments, see Figures 1 to 14The range hood includes a housing 10, a hinged plate 20, a baffle plate 30, a slide rail 40, and a side plate 50. The slide rail 40 is installed on the hinged plate 20. The baffle plate 30 is fixedly connected to the side plate 50. The first end 31 of the baffle plate 30 is located near the third end 51 of the side plate 50, and the second end 32 of the baffle plate 30 is located near the fourth end 52 of the side plate 50. The first end 31 is slidably connected to the slide rail 40 via the third end 51, and the second end 32, which is located opposite to the first end 31, is rotatably connected to the housing 10 via the fourth end 52. The baffle plate 30 and the housing 10 form a baffle cavity 110. The hinged plate 20 is located on the side of the baffle plate 30 away from the baffle cavity 110. The hinged plate 20 rotates relative to the housing 10 to drive the baffle plate 30 to rotate relative to the housing 10, so that the baffle plate 30 enters the unfolded state or the closed state synchronously with the hinged plate 20.
[0070] When the opening and closing plate 20 rotates towards the side away from the guide cavity 110, until the first end 31 rotates with the opening and closing plate 20 to the first end of the slide rail 40, the rotation direction a of the first end 31 is perpendicular to the rotation direction b of the opening and closing plate 20, and the range hood enters the unfolded state. The housing 10 forms a receiving cavity and a first opening communicating with the receiving cavity. In the closed state, the opening and closing plate 20 covers the first opening, and the guide plate 30 is disposed within the receiving cavity. In the closed state, the first included angle θ between the rotation direction a of the first end 31 and the rotation direction b of the opening and closing plate 20 is 5°.
[0071] The range hood includes two side plates 50 and two slide rails 40. The two side plates 50 are respectively located on both sides of the guide plate 30 and are fixedly connected to the guide plate 30. The two slide rails 40 are located on both sides of the opening and closing plate 20 and are correspondingly arranged with the side plates 50. Each slide rail 40 includes a sliding groove 410 and limiting plugs 42 located at both ends of the sliding groove 410. The third end 51 of the side plate 50 is provided with a hollow rivet 43 and a roller 44. One end of the hollow rivet 43 is located inside the roller 44. The roller 44 is located inside the sliding groove 410 and is slidably connected to the sliding groove 410. The hollow rivet 43 is also connected to the side plate 50. The roller 44 has a stepped structure, with the outer diameter of the roller 44 near the bottom of the sliding groove 410 being larger than the outer diameter of the roller 44 near the opening of the sliding groove 410. This structure effectively prevents the roller 44 from sliding out of the opening of the sliding groove 410, ensuring sliding stability.
[0072] Unlike existing technologies, the range hood of this application includes a housing, a hinged plate, and a baffle plate. The hinged plate is rotatably connected to the housing. A first end of the baffle plate slides along the hinged plate, and a second end opposite to the first end is rotatably connected to the housing. The baffle plate and the housing form a baffle cavity, and the hinged plate is located on the side of the baffle plate away from the baffle cavity. The hinged plate rotates relative to the housing, causing the baffle plate to rotate relative to the housing, thus allowing the baffle plate to simultaneously enter an unfolded state or a closed state. The hinged plate, located on the side of the baffle plate away from the baffle cavity, achieves smoke collection in the unfolded state and reduces the overall size of the range hood in the closed state. The hinged plate's rotatable connection to the housing, with a first end sliding along the hinged plate and a second end rotatably connected to the housing, allows the baffle plate to rotate relative to the housing, achieving opening and closing. This simple structure reduces costs and improves the reliability of the range hood.
