[0044] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.
[0045] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.
[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this applies. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0047] The following is combined Figures 1 to 7 The embodiments of this utility model will be described below. It should be understood that the following description is merely an illustrative embodiment of this utility model and does not constitute any limitation on this utility model.
[0048] Combination Figures 1 to 7 This utility model provides a smoke collection plate assembly, which is installed on a range hood. The range hood has a smoke collection hood 1 and a flip-up glass 2, with a side notch 3 formed between the smoke collection hood 1 and the flip-up glass 2. The smoke collection hood 1 has a smoke inlet and a smoke collection chamber. The smoke inlet is connected to the smoke collection chamber, and the fumes can enter the smoke collection chamber through the smoke inlet and then be discharged into the external environment.
[0049] The smoke collection plate assembly includes a first smoke collection plate 100 and a second smoke collection plate 200.
[0050] The first smoke-gathering plate 100 is hinged to the smoke-collecting hood 1 and is telescopically connected to the smoke-collecting chamber.
[0051] The first side of the second smoke-collecting plate 200 is connected to the flip-up glass 2, and the second side of the second smoke-collecting plate 200 is telescopically connected to the first smoke-collecting plate 100, forming a "large-enclosing-small" type.
[0052] When the range hood is in standby or off state, the second smoke-collecting plate 200 retracts into the first smoke-collecting plate 100, and the first smoke-collecting plate 100 retracts into the smoke collection chamber. Both the first smoke-collecting plate 100 and the second smoke-collecting plate 200 can retract into the smoke collection chamber, reducing the space occupied.
[0053] When the range hood is in low-speed mode, the first smoke-gathering plate 100 extends out of the smoke collection chamber, and the second smoke-gathering plate 200 retracts into the first smoke-gathering plate 100. At this time, the flip-up glass 2 opens to a first preset angle (e.g., 30°), and the first smoke-gathering plate 100 seals the side notch 3. The fumes are gathered into the smoke-gathering space formed by the flip-up glass 2, the first smoke-gathering plate 100, and the smoke collection hood 1. This smoke-gathering space is connected to the smoke collection chamber through the smoke inlet, which can reduce the escape of fumes and improve the smoke exhaust effect.
[0054] When the range hood is in high-end mode, the first smoke-collecting plate 100 extends out of the smoke collection chamber, and the second smoke-collecting plate 200 extends out of the first smoke-collecting plate 100. At this time, the flip-up glass 2 opens to a second preset angle (e.g., 60°), and the first smoke-collecting plate 100 and the second smoke-collecting plate 200 together seal the side notch 3. The smoke-collecting space formed by the flip-up glass 2, the first smoke-collecting plate 100, and the smoke collection hood 1 becomes larger, which can further reduce the escape of oil fumes and improve the smoke exhaust effect.
[0055] It is understood that the smoke-collecting plate assembly provided in the embodiments of this utility model, by setting a first smoke-collecting plate 100 and a second smoke-collecting plate 200, and extending and retracting the first smoke-collecting plate 100 to the smoke collection chamber, and extending and retracting the second smoke-collecting plate to the first smoke-collecting plate 100, allows both the first smoke-collecting plate 100 and the second smoke-collecting plate 200 to retract into the smoke collection chamber when the range hood is in standby or off state, thereby reducing the required installation space. When the range hood is in low-speed state, the first smoke-collecting plate 100 extends out of the smoke collection chamber to seal the side notch 3, preventing oil fumes from escaping and improving the smoke extraction effect. When the range hood is in high-speed state, the second smoke-collecting plate 200 extends out of the first smoke-collecting plate 100 and together seals the side notch 3, thereby expanding the smoke-collecting space, further reducing the escape of oil fumes, and improving the smoke extraction effect. Thus, the smoke-collecting plate occupies less installation space and has a better smoke-collecting effect, improving the user experience.
[0056] In addition, in some embodiments of this utility model, the first smoke-gathering plate 100 includes a first left smoke-gathering plate and a first right smoke-gathering plate, and the second smoke-gathering plate 200 includes a second left smoke-gathering plate and a second right smoke-gathering plate. The side notch 3 includes a left notch and a right notch.
[0057] The first left smoke-gathering plate and the first right smoke-gathering plate are symmetrically arranged, and the second left smoke-gathering plate and the second right smoke-gathering plate are symmetrically arranged.
[0058] Both the first left smoke gathering plate and the second left smoke gathering plate are provided with a notch on the left side. The first left smoke gathering plate is telescopically located in the smoke collection chamber, and the second left smoke gathering plate is telescopically connected to the first left smoke gathering plate.
[0059] Both the first and second right smoke collectors have notches on the right side. The first right smoke collector is telescopically located within the smoke collection chamber, and the second right smoke collector is telescopically connected to the first left smoke collector. This allows both the left and right notches to be covered, further improving the smoke extraction effect.
[0060] Specifically, in combination Figure 4 In some embodiments of this utility model, the smoke collection plate assembly further includes a hinge 300 and a return spring 400.
[0061] The first end of the hinge 300 is hinged to the smoke hood 1, and the second end of the hinge 300 is fixedly connected to the first smoke collection plate 100.
[0062] The first end of the return spring 400 is fixed to the smoke hood 1, and the second end of the return spring 400 is connected to the second end of the hinge 300.
[0063] When the range hood is turned off, the first smoke-collecting plate 100 will be pulled into the smoke collection chamber by the elastic force of the return spring 400 to save space.
[0064] Combination Figure 4 In some embodiments of this utility model, in order to make the reset spring 400 more securely fixed, the smoke collection plate assembly also includes a spring bracket 410.
[0065] The spring bracket 410 is installed in the smoke hood 1, and the first end of the return spring 400 is fixed to the spring bracket 410.
[0066] Combination Figure 5 In order to make the coordination between the extension and retraction of the first smoke-gathering plate 100 and the second smoke-gathering plate 200 and the opening and closing of the flip glass 2 more reasonable and flexible, in some embodiments of this utility model, the smoke-gathering plate assembly also includes a rocker arm 500 and a push rod 510.
[0067] The first end of the rocker arm 500 is hinged to the smoke hood 1, and the second end of the rocker arm 500 is fixedly connected to the flip-up glass 2.
[0068] The first end of the push rod 510 is fixed to the smoke hood 1, and the second end of the push rod 510 is hinged to the rocker arm 500.
[0069] When the range hood is on the low setting, the push rod 510 extends and can open the flip glass 2 to the first preset angle (e.g., 30°), and the first smoke collection plate 100 extends out of the smoke collection chamber.
[0070] When the range hood is in high position, the push rod 510 continues to extend, which can open the flip glass 2 to the second preset angle (e.g., 60°), and at the same time the second smoke collection plate 200 is pulled out from the first smoke collection plate 100.
[0071] When the range hood is off or in standby mode, the push rod 510 retracts, which can close the flip glass 2. The second smoke collecting plate 200 retracts into the first smoke collecting plate 100, and the first smoke collecting plate 100 is pulled into the smoke collection chamber under the action of the return spring 400.
[0072] Of course, the 510 linear actuator can be an electric linear actuator, which facilitates electrical control and improves efficiency.
[0073] Combination Figures 2 to 4 In some embodiments of this utility model, the first smoke-gathering plate 100 is provided with a telescopic groove 110, and the second smoke-gathering plate 200 is telescopically connected to the telescopic groove 110. The telescopic groove 110 can prevent the second smoke-gathering plate 200 from slipping out during the telescopic process, and ensure the stability of the telescopic movement of the second smoke-gathering plate 200.
[0074] Furthermore, a limiting post 210 is provided on the second side of the second smoke collection plate 200, and the limiting post 210 matches the telescopic groove 110.
[0075] When the limiting post 210 slides to the end of the telescopic groove 110, the limiting post 210 restricts the second smoke-collecting plate 200 from sliding out of the telescopic groove 110; the limiting post 210 can prevent the second smoke-collecting plate 200 from sliding out from the end of the first smoke-collecting plate 100, thereby ensuring the stability of the telescopic movement of the second smoke-collecting plate 200.
[0076] Combination Figure 4 and Figure 6 In some embodiments of this utility model, when the range hood is in a low-speed state, the opening angle of the flip glass 2 is α, 30°≤α≤50°, where α can be 30° or 50°; this avoids the angle being too large, which would affect the space, and allows the smoke collection space to be adjusted for flexible smoke exhaust.
[0077] When the range hood is in high-end mode, the opening angle of the flip glass 2 is β, 60°≤β≤90°, where β can be 60° or 90°; this avoids the smoke collection space being too small due to the flip glass 2 being too small, which would affect the smoke exhaust effect.
[0078] Combination Figures 1 to 7 In an embodiment of this utility model, a range hood is also provided, which includes the above-mentioned smoke collection plate assembly and range hood body.
[0079] The smoke collection plate assembly is installed on the main body of the range hood.
[0080] It is understandable that the range hood provided by this utility model, since it includes the aforementioned smoke-collecting plate assembly, will inevitably possess all the advantages of that assembly. That is, the range hood can also reduce the installation space occupied by the smoke-collecting plate and improve the smoke collection effect, thereby enhancing the user experience.
