[0002] Existing range hoods usually include a housing, which has a smoke collecting chamber, and a smoke inlet is provided on the front side wall of the smoke collecting chamber. A flap for opening or closing the smoke inlet is rotatably installed at the smoke inlet, and a front side panel is installed above the smoke inlet. The front side panel is usually a glass panel. Since the flap is generally rotatably installed on the housing through a hinge shaft in the prior art, a large gap is set between the flap and the front side panel to avoid interference between the flap and the front side panel during the flipping process, thereby protecting the flap and the front side panel and ensuring that the range hood can work normally. However, the existence of the gap not only easily affects the overall aesthetics of the range hood, but also easily causes some oil smoke to be discharged from the gap into the kitchen, reducing the smoke intake rate of the range hood and seriously affecting the air quality in the kitchen.

[0042] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0043] Reference Figures 1 to 11 In one embodiment of the utility model, a range hood flap structure is provided, comprising a housing 100, a flap 130 and a baffle 200. The housing 100 has a smoke collecting chamber 110, a smoke inlet is provided on the front side wall of the smoke collecting chamber 110, and the housing 100 is provided with a front side plate 120 located on the upper side of the smoke inlet. The flap 130 is rotatably mounted on the housing 100 and is located at the smoke inlet, and a gap is provided between the upper edge of the flap 130 and the lower edge of the front side plate 120. The baffle 200 has a shielding portion 210 located in the gap, and the front side surface of the shielding portion 210 has an arc surface 211. The shielding portion 210 is relatively fixed to the front side plate 120 and the arc surface 211 can avoid the flap 130. When the flap 130 rotates relative to the housing 100, the upper edge of the flap 130 is close to the arc surface 211.

[0044] In the above structure, by setting the blocking bar 200, the blocking bar 200 has a shielding portion 210 located in the gap between the flap 130 and the front side plate 120, and the front side surface of the shielding portion 210 has a curved surface 211, the shielding portion 210 is relatively fixed to the front side plate 120 and the curved surface 211 can avoid the flap 130. Therefore, when the flap 130 is flipped to open or close the smoke inlet, the upper edge of the flap 130 is close to the curved surface 211 of the shielding portion 210 and can move along the curved surface 211, thereby avoiding the flap 130 from colliding with the front side plate 120 or the shielding portion 210 during the flipping process, that is, avoiding the flap 130 from interfering with the front side plate 120 or the shielding portion 210 during the flipping process, thereby ensuring the smooth flipping of the flap 130 and protecting the flap 130, the front side plate 120 and the blocking bar 200. In addition, since the shielding portion 210 of the baffle 200 can fill the gap between the upper end of the flap 130 and the lower end of the front side panel 120, it can not only improve the aesthetics of the range hood, but also reduce the amount of oil smoke discharged from the gap to the kitchen, thereby improving the smoke intake rate of the range hood.

[0045] It can be understood that the arc surface 211 can be specifically set according to the movement trajectory of the upper edge of the flap 130 when the flap 130 rotates.

[0046] It can be understood that in order for the shielding portion 210 of the blocking bar 200 to fill the gap between the upper end of the flap 130 and the lower end of the front side plate 120 and avoid interference with the flipping of the flap 130, in addition to fixing the shielding portion 210 and the front side plate 120 relatively and allowing the arc surface 211 to avoid the flap 130, when the flap 130 rotates relative to the housing 100, the upper edge of the flap 130 is close to the arc surface 211. In some embodiments, the shielding portion 210 can also be movably arranged in the gap so that the shielding portion 210 can be fixed to the front side plate 120. The portion 210 can follow the flap 130 to flip and the arc surface 211 can avoid the front side plate 120. When the flap 130 rotates relative to the housing 100, the lower edge of the front side plate 120 is close to the arc surface 211, thereby preventing the flap 130 from colliding with the front side plate 120 during the flipping process, that is, preventing the flap 130 from interfering with the front side plate 120 during the flipping process, thereby ensuring the smooth flipping of the flap 130 and protecting the flap 130, the front side plate 120 and the blocking bar 200. In addition, since the shielding portion 210 of the blocking bar 200 can fill the gap between the upper end of the flap 130 and the lower end of the front side plate 120, it can not only improve the aesthetics of the range hood, but also reduce the amount of oil smoke discharged from the gap to the kitchen, thereby improving the smoke intake rate of the range hood.

[0047] In some embodiments, the upper end of the shielding portion 210 abuts against the lower end of the front side plate 120 , and the flap 130 can be flipped relative to the shielding portion 210 .

[0048] In the above structure, by abutting the upper end of the shielding portion 210 against the lower end of the front side plate 120, the gap between the front side plate 120 and the flap 130 can be filled to a greater extent, thereby further improving the aesthetics of the range hood, and at the same time, further reducing the amount of oil smoke discharged from the gap into the kitchen, increasing the smoke intake rate of the range hood, and helping to improve the air quality in the kitchen.

[0049] Reference Figure 6 As with 7, in some embodiments, the left end of the shielding portion 210 extends leftward to the left end adjacent to the front side plate 120; the right end of the shielding portion 210 extends rightward to the right end adjacent to the front side plate 120.

[0050] By adopting the above structure, the shielding part 210 can be prevented from protruding to the left and right sides of the front side panel 120, which not only improves the overall aesthetics of the range hood, but also prevents the left and right ends of the shielding part 210 from causing scratches to the user, thereby protecting the user and improving the user experience.

[0051] It is understandable that, in order to prevent the shielding portion 210 from protruding to the left side of the front side plate 120, in addition to extending the left end of the shielding portion 210 to the left to the left end adjacent to the left end of the front side plate 120, the left end of the shielding portion 210 can also be extended to the left to be flush with the left end of the front side plate 120, thereby making the range hood more beautiful. Similarly, in order to prevent the shielding portion 210 from protruding to the right side of the front side plate 120, in addition to extending the right end of the shielding portion 210 to the right to the right end adjacent to the front side plate 120, the right end of the shielding portion 210 can also be extended to the right to be flush with the right end of the front side plate 120, thereby making the range hood more beautiful.

[0052] Reference Figures 1 to 13 In some embodiments, the housing 100 has a mounting plate 300 located on the inner side of the front side plate 120, the baffle 200 has a connecting portion 220 connected to the shielding portion 210, the connecting portion 220 extends between the mounting plate 300 and the front side plate 120, and the connecting portion 220 is installed on the mounting plate 300.

[0053] By adopting the above structure, the shielding portion 210 can be installed on the mounting plate 300 of the casing 100 through the connecting portion 220, so that the shielding portion 210 can be more firmly installed on the casing 100. In addition, the connecting portion 220 extends between the mounting plate 300 and the front side plate 120, that is, it is located inside the smoke collecting chamber 110, thereby preventing the connecting portion 220 from being exposed to the outside of the range hood and affecting the overall aesthetics of the range hood.

[0054] It can be understood that, in some embodiments, the housing 100 further has a left side panel and a right side panel, and the mounting plate 300 can be specifically connected to the left side panel and the right side panel, thereby enabling the installation of the mounting plate 300 to be more firmly and stably installed.

[0055] Reference Figures 1 to 13 In some embodiments, a countersunk hole 221 is formed on the front surface of the connecting portion 220, and a mounting hole 310 corresponding to the countersunk hole 221 is formed on the mounting plate 300. The countersunk hole 221 is installed with a fastener extending to the corresponding mounting hole 310, and the front end of the fastener is located inside the countersunk hole 221 or flush with the front surface of the connecting portion 220.

[0056] By adopting the above structure, the connecting part 220 can be installed on the mounting plate 300 by means of fasteners, and by opening a countersunk hole 221 in the connecting part 220, the fastener is installed in the countersunk hole 221, and the front end of the fastener is located inside the countersunk hole 221 or flush with the front side surface of the connecting part 220, thereby preventing the fastener from protruding from the front side surface of the connecting part 220 and interfering with the installation of the front side plate 120, thereby facilitating the installation of the front side plate 120 and ensuring the surface flatness of the front side plate 120 after installation.

[0057] It can be understood that, in some embodiments, the front side panel 120 is a glass panel. Since the front end of the fastener is located inside the countersunk hole 221 or is flush with the front surface of the connecting part 220, the glass panel can be fitted with the front surface of the connecting part 220, thereby facilitating the installation of the front side panel 120 and ensuring the surface flatness of the front side panel 120 after installation.

[0058] Reference Figures 1 to 11 In some embodiments, the connecting portion 220 and the shielding portion 210 are an integrated structure.

[0059] In the above structure, by setting the connecting portion 220 and the shielding portion 210 of the baffle bar 200 as an integrated structure, the production and processing of the baffle bar 200 can be facilitated, and the number of components of the baffle bar 200 is reduced, thereby saving the time for installing and assembling the components of the baffle bar 200. In addition, by setting the connecting portion 220 and the shielding portion 210 of the baffle bar 200 as an integrated structure, the structural strength of the baffle bar 200 can be improved, and deformation and bending of the baffle bar 200 can be avoided.

[0060] In some embodiments, the blocking bar 200 may be an aluminum bar.

[0061] In the above structure, since the aluminum strip is light, the weight of the baffle 200 can be reduced, and the weight of the range hood as a whole can be reduced, making the range hood more portable. Secondly, since the aluminum strip is soft, even if the flap 130 interferes when turning over, it is not easy to cause damage to the flap 130 or the front side plate 120. In addition, the aluminum strip is easily oxidized into various colors, so the aluminum strip can be oxidized into a desired color according to needs, thereby further improving the overall aesthetics of the range hood.

[0062] It is understandable that in order to avoid damage to the flap 130 or the front side panel 120 when interference occurs when the flap 130 is flipped, in addition to setting the baffle 200 as an aluminum bar, in some other embodiments, the baffle 200 can also be set as a rubber strip, and the present invention does not make any specific limitation on this.

[0063] Reference Figures 1 to 13 In some embodiments, the front surface of the mounting plate 300 is a plane, and the connecting portion 220 is in contact with the front surface of the mounting plate 300 .

[0064] By adopting the above structure, the flatness of the connecting part 220 after being installed on the mounting plate 300 can be ensured, thereby not only facilitating the front side plate 120 to fit the front surface of the connecting part 220, but also facilitating the support and protection of the mounting part to avoid deformation of the mounting part due to local force.

[0065] Reference Figures 1 to 9In some embodiments, an oil net 140 is installed at the smoke inlet, the lower end of the connecting portion 220 has a bent portion 320 bent backward, and the upper end of the oil net 140 is adjacent to or abuts against the bent portion 320 .

[0066] In the above structure, the oil net 140 can filter the oil smoke entering the smoke collecting chamber 110 through the smoke inlet, absorb the oil in the oil smoke and guide the oil to flow to the bottom of the smoke collecting chamber 110. By providing a bent portion 320 bent backward at the lower end of the connecting portion 220, and placing the upper end of the oil net 140 close to or abutting against the bent portion 320, the installation arrangement between the various components of the range hood can be made more compact, and the arrangement of the oil net 140 can be made more stable.

[0067] An embodiment of the present invention further provides a range hood, which is provided with the range hood flap structure of any of the above embodiments.

[0068] In the above structure, by setting the range hood flap structure of any of the above embodiments, the baffle 200 has a shielding portion 210 located between the upper end of the flap 130 and the lower end of the front side panel 120. The shielding portion 210 can fill the gap between the upper end of the flap 130 and the lower end of the front side panel 120, thereby improving the overall aesthetics and smoke intake rate of the range hood, while also avoiding collision interference with the flipping of the flap 130, so that the flap 130 can be smoothly flipped to open or close the smoke inlet, and can protect the front side panel 120 and the flap 130.

[0069] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
