[Specific implementation method]
[0030] In order to make the purpose, scheme and beneficial effects of this application clearer, this application is further described below in conjunction with the accompanying drawings and preferred embodiments.
[0031] In the related art, since the guide rail assembly is in contact with oil smoke inside the chassis, especially when the smoke collection module is in the descending stage, the expansion of the guide rail assembly causes its internal moving connection position to be directly exposed to the oil smoke, which is prone to adhesion, movement obstruction and other problems after a long time, affecting the normal use of the lifting range hood.
[0032] To this end, the present application provides a guide rail assembly and a range hood, which can at least solve the technical problems existing in the prior art to a certain extent.
[0033] Example 1:
[0034] The present application provides a guide rail assembly 100, which is applied to a range hood, such as Figures 1 to 3 1 and 2 are structural diagrams of the guide rail assembly 100 in different states and viewing angles. The guide rail assembly 100 includes a first guide rail 110, a second guide rail 120, and an oil retaining member 130. A movable connecting member 140 is provided between the first guide rail 110 and the second guide rail 120 to enable relative movement between the two.
[0035] It can be understood that the guide rail assembly 100 has two states: folded and open. When the guide rail assembly 100 is in the open state or switching between the two states, at least a portion of the movable connecting member 140 located in the middle will be exposed to the oil smoke. For this reason, the oil baffle 130 is constructed to at least prevent part of the oil smoke from contacting the movable connecting member 140 to ensure that the guide rail assembly 100 can move normally in the range hood.
[0036] Specifically, the guide rail assembly 100 further includes a driving mechanism (not shown) for driving the second guide rail 120 to move up and down. Figure 3 As shown, taking descent as an example, after the second guide rail 120 descends, the movable connecting member 140 is no longer hidden, and the oil smoke will contact the movable connecting member 140 from the direction of the original position of the second guide rail 120. Therefore, the oil baffle 130 is vertically arranged on the outer side of the guide rail assembly 100 close to the second guide rail 120, which can prevent the oil smoke from this direction from contacting the movable connecting member 140.
[0037] Furthermore, if Figure 2 As shown, the first guide rail 110 includes an oil-proof folding edge 111 and a first guide rail body 112 connected to the movable connecting member 140, and the second guide rail 120 includes a guide rail bracket 121 and a second guide rail body 122 connected to the movable connecting member 140. The movable connecting member 140 is clamped between the first guide rail body 112 and the second guide rail body 122 so that the two can move relative to each other. The specific movement mode can be sliding or rolling, which is not limited here.
[0038] Among them, the oil-proof folding edge 111 is constructed to be basically perpendicular to the above-mentioned two guide rail bodies and prevent the oil smoke from contacting the movable connecting member 140 between the two. From a top-down perspective, the oil-blocking member 130, the oil-proof folding edge 111 and the first guide rail body 112 form a relatively complete U-shaped structure that sequentially surrounds the movable connecting member 140.
[0039] Furthermore, the guide rail bracket 121 of the second guide rail 120 is used to connect and drive the relevant components of the range hood to move up and down. For this purpose, a gap is left between the oil baffle 130 and the oil-proof folding edge 111 for the guide rail bracket 121 to pass through.
[0040] The vertical length of the oil baffle 130 should be no less than the displacement length of the second guide rail 120 during its lifting motion. For example, in the aforementioned guide rail assembly 100, when the second guide rail 120 is lowered to open the guide rail assembly 100, the vertical length of the oil baffle 130 should at least cover the displacement of the highest point of the second guide rail 120. This ensures that the oil baffle 130 can always shield the movable connector 140 throughout the entire travel of the second guide rail 120.
[0041] Example 2:
[0042] Based on the same inventive concept, an embodiment of the present application provides a range hood comprising a fan housing 200, a smoke collection housing 300, and a guide rail assembly 100. The smoke collection housing 300 is escalably connected to the fan housing 200 via the guide rail assembly 100. The guide rail assembly 100 comprises a first guide rail 110 and a second guide rail 120, each connecting the fan housing 200 and the smoke collection housing 300. A movable connector 140 is provided between the first guide rail 110 and the second guide rail 120 to enable relative movement between the first guide rail 110 and the second guide rail 120.
[0043] It is understandable that when the range hood is working, the smoke collection box 300 descends under the drive of the second guide rail 120, and a large amount of oil smoke is sucked into the fan box 200. At least a part of the movable connecting member 140 located between the above two guide rails will be exposed to the oil smoke. For this reason, the guide rail assembly 300 is provided with an oil baffle 130, and the oil baffle 130 is constructed to at least prevent part of the oil smoke from contacting the movable connecting member 140 to ensure that the smoke collection box 300 can be raised and lowered normally in the range hood.
[0044] In an optional embodiment, the first guide rail 110 is fixed to the inner wall of the smoke collecting box 300, such as Figure 5 As shown, the first guide rail 110 is fixed to the rear wall of the smoke collecting box 300 , and of course it can also be the front wall or the side wall, which is not limited here.
[0045] The second guide rail 120 is connected to the movable connecting member 140 in a liftable manner, which may mean that the second guide rail 120 is movable relative to the movable connecting member 140, or at least a portion of the movable connecting member 140 is movable relative to the first guide rail 110 to drive the second guide rail 120. Taking the second case as an example, Figure 3 and Figure 5As shown, the movable connecting member 140 includes a first connecting portion 141 and a second connecting portion 142 which are respectively fixed to the first guide rail 110 and the second guide rail 120. The two connecting portions can slide relative to each other, and the smoke collecting box body 300 is driven by the second connecting portion 142 to perform lifting and lowering movements. When the smoke collecting box body 300 is in the second position, the setting of the oil baffle 300 can effectively prevent the oil smoke from contaminating the first connecting portion 141.
[0046] After the second guide rail 120 descends, the movable connecting member 140 is no longer hidden, and the oil smoke will contact the movable connecting member 140 from the direction of the original position of the second guide rail 120. Therefore, the oil baffle 130 is vertically arranged on the outer side of the guide rail assembly 100 close to the second guide rail 120 to prevent the oil smoke from this direction from contacting the movable connecting member 140.
[0047] Furthermore, the smoke collecting box 300 includes a first position accommodated in the fan box 200 and a second position extending downward from the fan box 200. Figure 5 As shown; the first guide rail 110 includes an oil-proof folding edge 111 and a first guide rail body 112 connected to the movable connecting member 140; the second guide rail 120 includes a guide rail bracket 121 and a second guide rail body 122 connected to the movable connecting member 140, and the movable connecting member 140 is clamped between the first guide rail body 112 and the second guide rail body 122 so that the two can move relative to each other. The specific movement method can be sliding or rolling, which is not limited here.
[0048] Among them, the oil-proof folding edge 111 is constructed to be basically perpendicular to the above-mentioned two guide rail bodies and prevent the oil smoke from contacting the movable connecting member 140 between the two. When the smoke collecting box 300 is in the second position, the oil-proof folding edge 111 and the first guide rail body 112 form a relatively complete U-shaped structure that sequentially surrounds the movable connecting member 140.
[0049] Furthermore, the guide rail bracket 121 of the second guide rail 120 is used to connect and drive the smoke collecting box 300 to move up and down. For this purpose, a gap is left between the oil blocking member 130 and the oil-proof folding edge 111 for the guide rail bracket 121 to pass through.
[0050] In an optional embodiment, as Figure 5 As shown, the oil retaining member 130 and the first guide rail 110 are vertically arranged on the rear wall of the fan housing 200. Specifically, as Figure 2 As shown, the oil blocking member 130 and the first guide rail 110 are respectively provided with an oil blocking fixing member 131 and a guide rail fixing member 113 fixedly connected to the rear wall of the box.
[0051] The vertical length of the oil baffle 130 should be no less than the displacement length of the second guide rail 120 during its lifting motion. In Example 2, when the smoke collecting box 200 moves from the first position to the second position, the vertical length of the oil baffle 130 should at least cover the displacement of the highest point of the second guide rail 120 during this stroke, thereby ensuring that the oil baffle 130 can always shield the movable connector 140.
[0052] The components of different embodiments can be combined with each other in any feasible manner to achieve the purpose of this application.
[0053] It should be noted that this application should not be construed as limited to the embodiments described above, but rather should be construed as covering all possible implementations determined by the claims of this application in conjunction with the disclosure of the specification. Therefore, any simple modifications, equivalent variations, and modifications to the above embodiments that do not depart from the technical solution of this application and are based on the technical essence of this application fall within the scope of protection of the technical solution of this application.
