[0059] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.
[0060] like Figures 1 to 6As shown, the present embodiment provides a range hood 100, which includes a smoke hood 1, a diverter 2, a sensor and a positioning member. The smoke hood 1 has an air inlet 111 on its air inlet surface 11 facing the cooker, and the diverter 2 is movably connected to the air inlet 111 for switching the state of the air inlet 111. In a first state, in the axial direction of the air inlet 111, the projection of the diverter 2 completely covers the air inlet 111, and the air inlet 111 is closed. In a second state, at least part of the diverter 2 is separated from the air inlet 111, and the air inlet 111 is opened. One of the areas between the diverter 2 and the air inlet surface 11 where the air inlet 111 is not provided is connected to the sensor, and the other is connected to a positioning member matching the sensor, for position detection during the movement of the diverter 2. Specifically, when the diverter 2 moves relative to the air inlet 111, the operator can obtain the position of the diverter 2 or the displacement of the diverter 2 based on the sensor, so as to avoid the diverter 2 from colliding with other parts during the movement, which is beneficial to improve the service life of the diverter 2 and improve the reliability and stability of the movement of the diverter 2. In addition, with the above-mentioned structural form, in the first state, that is, when the range hood 100 is not working, the diverter 2 closes the air inlet 111, which can prevent the oil in the smoke hood 1 from dripping from the air inlet 111; in the second state, the air inlet 111 is opened, and the oil smoke can be absorbed through the air inlet 111 to prevent the oil smoke from escaping.
[0061] It should be specifically explained that, in this embodiment, the first state is the state in which the range hood 100 is not in operation; the second state is the state in which the range hood is in operation, or the state in which the range hood is cleaned. In addition, the aforementioned splitter 2 and the area of the air inlet surface 11 without the air inlet 111 are connected to the sensing element, and the other is connected to the positioning element matched with the sensing element, which means that when the sensing element is connected to the splitter 2, the positioning element is connected to the area of the air inlet surface 11 without the air inlet 111; when the sensing element is connected to the area of the air inlet surface 11 with the air inlet 111, the positioning element is connected to the splitter 2.
[0062] During specific use, the flow divider 2 is in the shape of a plate. In other embodiments, the shape of the flow divider 2 can be adjusted according to actual needs, which is not limited here.
[0063] like Figure 1As shown, the diverter 2 is rotatably connected to the air inlet 111. In the second state, at least part of the diverter 2 is tilted from the air inlet 111 to the inside of the smoke hood 1, wherein the rotation axis of the diverter 2 is located in the plane where the diverter 2 is located. Specifically, the diverter 2 is rotatably connected to the air inlet 111, which improves the movement accuracy of the diverter 2 relative to the air inlet 111. In addition, with the above-mentioned structural form, in the first state, the diverter 2 and the surface of the diverter 2 facing the stove are located in the same horizontal plane as the air inlet surface 11, preventing the diverter 2 from protruding from the air inlet surface 11 and causing the operator to be easily injured; in the second state, the diverter 2 rotates relative to the air inlet 111, so that the diverter 2 is tilted, so that the oil smoke can be guided from the air inlet 111 to the inside of the smoke hood 1 through the extension direction of the diverter 2, thereby improving the adsorption efficiency of the range hood 100.
[0064] In this embodiment, the diverter 2 is rotatably connected to the air inlet 111, thereby realizing an active connection between the diverter 2 and the air inlet 111. In other embodiments, the diverter 2 and the air inlet 111 may also be slidably connected. The specific active connection form between the diverter 2 and the air inlet 111 is not limited herein.
[0065] It should be specifically explained that the rotational connection between the diverter 2 and the air inlet 111 is located in the middle of the side of the diverter 2, so in the second state, part of the diverter 2 rotates to the inside of the smoke hood 1, and part of the diverter 2 extends out of the smoke hood 1. In addition, when the range hood 100 is not working and the operator wants to clean the inside of the smoke hood 1, the diverter 2 can also rotate relative to the air inlet 111, and part of the air inlet 111 is opened, so that the operator can clean the oil stains inside the smoke hood 1. Figure 1 and Figure 3 As shown, this embodiment is schematically expressed by taking the example that when the range hood 100 is in the second state, the upper part of the diverter 2 rotates toward the inside of the smoke hood 1; when the range hood 100 needs to be cleaned, the upper part of the diverter 2 rotates toward the outside of the smoke hood 1. In other embodiments, the rotation direction of the diverter 2 can be adjusted according to actual needs, and the specific rotation direction of the diverter 2 is limited here.
[0066] In this embodiment, the extension direction of the rotation axis of the diverter 2 is parallel to the length direction of the diverter 2, which reduces the rotation radius of the diverter 2, thereby reducing the risk of interference between the diverter 2 and other components during the rotation process, and improving the stability and reliability of the movement of the diverter 2. In other embodiments, the extension direction of the rotation axis of the diverter 2 can also be other directions, as long as the extension direction of the rotation axis is located in the plane where the diverter 2 is located.
[0067] like Figures 3 to 6As shown, the range hood 100 further includes a driving member 3 and a moving member 4, wherein the driving member 3 is connected to the area of the air inlet surface 11 where the air inlet 111 is not provided, and the driving member 3 is provided with a first sawtooth 32 on at least the surface facing the moving member 4, and the moving member 4 is connected to the diverter 2, and the outer peripheral surface of the moving member 4 is provided with a second sawtooth 42 meshing with the first sawtooth 32; wherein the rotation axis of the second sawtooth 42 coincides with the rotation axis of the diverter 2. With the above-mentioned structural form, the diverter 2 can move according to a preset path and speed, thereby improving the movement accuracy of the diverter 2.
[0068] In this embodiment, a first gear 31 is provided at one end of the driving member 3 close to the moving member 4, a second gear 41 is provided at one end of the moving member 4 close to the driving member 3, a first sawtooth 32 is provided on the first gear 31, and a second sawtooth 42 is provided on the second gear 41; wherein, the rotation axis of the first gear 31 is not parallel to the rotation axis of the second gear 41. With the above-mentioned structural form, the meshing of the first gear 31 and the second gear 41 is achieved through the cooperation of the first gear 31 and the second gear 41, thereby improving the movement accuracy of the diverter 2. In other embodiments, the meshing of the first sawtooth 32 and the second sawtooth 42 can also be achieved in the form of a gear rack, and the specific form of achieving the meshing is not limited here.
[0069] In this embodiment, the extension direction of the rotation axis of the first gear 31 is perpendicular to the extension direction of the rotation axis of the second gear 41, which improves the compactness of the connection between the driving member 3 and the moving member 4. In other embodiments, the extension direction of the rotation axis of the first gear 31 and the extension direction of the rotation axis of the second gear 41 may also be at other angles, and the specific angle is not limited here.
[0070] like Figure 4 and Figure 5 As shown, the driving member 3 includes a motor 33, a mounting portion 34 and a fixing portion 35. The mounting portion 34 is connected to the area of the air inlet surface 11 where the air inlet 111 is not provided. The fixing portion 35 is covered on the mounting portion 34 and encloses an installation area for installing the motor 33. The output end of the motor 33 is connected to the first gear 31. Specifically, the first gear 31 is driven to move by the motor 33, so that the movement can be transmitted to the second gear 41 through the first gear 31, and the diverter 2 is driven to move. With the above-mentioned structural form, the connection between the motor 33 and the area of the air inlet surface 11 where the air inlet 111 is not provided is realized through the mounting portion 34 and the fixing portion 35, and the stability and reliability of the connection of the motor 33 are improved through the mounting area enclosed by the mounting portion 34 and the fixing portion 35.
[0071] like Figures 4 to 6As shown, the moving part 4 includes a support seat 43, a fixed seat 44 and a linkage shaft 45. The support seat 43 is connected to the area of the air inlet surface 11 where the air inlet 111 is not provided. The fixed seat 44 is connected to the diverter 2. The linkage shaft 45 passes through the support seat 43, and the two ends of the linkage shaft 45 are respectively connected to the second gear 41 and the fixed seat 44. Specifically, the motor 33 drives the first gear 31 to rotate. Since the first gear 31 and the second gear 41 are meshed, the rotation can be transmitted to the second gear 41, and the linkage shaft 45 is driven to rotate through the second gear 41, so that the diverter 2 can be driven to move through the fixed seat 44. In addition, by adopting the above-mentioned structural form, the movement direction of the linkage shaft 45 can be limited by the support seat 43, so that the linkage shaft 45 can only rotate along the axis of the linkage shaft 45, thereby improving the stability and reliability of the movement of the linkage shaft 45 and the fixed seat 44, thereby improving the stability and reliability of the movement of the diverter 2.
[0072] In specific use, when assembling the moving part 4, the boss 6 on the second gear 41 is placed on the support seat 43 facing the origin sensing unit 5, and then the moving part 4 is automatically adjusted to achieve the calibration of the second gear 41. Specifically, the motor 33 is powered on and rotates, and when the origin sensing unit 5 recognizes the boss 6, the motor 33 stops rotating, and the second gear 41 moves and stays at the origin position.
[0073] There are multiple driving members 3 and multiple moving members 4, and the multiple driving members 3 are connected to the multiple moving members 4 in a one-to-one correspondence. The multiple driving members 3 are symmetrically arranged at both ends of the diverter 2, thereby improving the stability and reliability of the movement of the diverter 2.
[0074] In this embodiment, if Figure 4 As shown, the number of the moving parts 4 is two as an example for schematic expression. In other embodiments, the number of the moving parts 4 can be adjusted according to actual needs, and is not limited here.
[0075] The sensing element includes two limit sensing parts, which are set on the moving path of the diverter 2 and correspond to the front limit position and the rear limit position respectively. When the positioning element moves to the front limit position or the rear limit position, the front limit position or the rear limit position is triggered, and the diverter 2 is controlled not to move forward or backward further. The above structural form avoids the diverter 2 from moving beyond the limit position and causing the diverter 2 to collide with other components, thereby improving the safety and stability of the diverter 2.
[0076] This embodiment also provides a kitchen system, which includes a range hood 100. Specifically, when the diverter 2 moves relative to the air inlet 111, the operator can obtain the position of the diverter 2 or the displacement of the diverter 2 based on the sensor, so as to avoid the diverter 2 from colliding with other parts during the movement, which is beneficial to improve the service life of the diverter 2 and improve the reliability and stability of the movement of the diverter 2. In addition, with the above-mentioned structural form, in the first state, that is, when the range hood 100 is not working, the diverter 2 closes the air inlet 111, which can prevent the oil stains in the smoke hood 1 from dripping from the air inlet 111; in the second state, the air inlet 111 is opened, and the oil smoke can be absorbed through the air inlet 111 to prevent the oil smoke from escaping.
[0077] In specific use, the kitchen system is a combination of common kitchen appliances such as a range hood 100 and a stove that are commonly used in daily kitchens.
