[Specific implementation method]
[0029] 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.
[0030] See also Figure 1 and Figure 2 A range hood includes a fan casing 1, a fume hood 2 arranged below the fan casing 1, an oil guide strip assembly 3 and an oil net 4. After long-term use of the range hood, grease tends to accumulate on the inner wall of the fan casing 1. The oil guide strip assembly 3 located below it is used to guide the flowing grease into the oil net 4 and finally collect it into the oil cup of the range hood (not shown).
[0031] like Figure 1As shown, the fan housing 1 includes a front panel 10, and first and second side panels 11 and 12 located on either side of the front panel 10. The smoke hood 2 includes a mounting plate 20 that cooperates with the front panel 10. The mounting plate 20 is configured to be arranged generally horizontally to accommodate fan housings 1 of varying depths. In many existing designs, the mounting area of the smoke hood 20 is often enclosed to form a vertical mounting opening for inserting the fan housing 1. However, once the size of the fan housing 1 changes, the original mounting opening becomes unsuitable. Therefore, manufacturers need to produce smoke hoods 20 with different mounting opening sizes.
[0032] In this application, when the mounting plate 20 of the smoke hood 2 is arranged approximately horizontally, the lower portion of the front plate 10 can be connected to different positions of the mounting plate 20 for fan casings 1 of different depths, thereby improving the versatility of the smoke hood 2. However, this approximately perpendicular connection between the front plate 10 and the mounting plate 20 is prone to oil leakage at the corner between the two. Therefore, this application also designs an oil guide bar assembly 3.
[0033] The oil guide strip assembly 3 includes a connecting plate 30 located on the outside of the front plate 10 and a first oil guide plate 31 located on the inner side of the front plate 10 and covering the mounting plate 20. Figure 3 As shown, the connecting plate 30 and the first oil guide plate 31 are connected in an L-shape. The connecting plate 30 is connected to the outside of the front plate 10, and the first oil guide plate 31 extends rearward from between the front plate 10 and the mounting plate 20. As a result, grease from the inner wall of the front plate 10 only lands on the first oil guide plate 31, eliminating the problem of oil leakage between the front plate 10 and the horizontal mounting plate 20. Furthermore, the oil guide strip assembly 3 includes a second oil guide plate 32, which is used to direct grease from the first oil guide plate 31 to the oil screen 4.
[0034] In the above structure, some grease may still seep out from the gap between the first oil guide plate 31 and the first side plate 11. Therefore, according to an exemplary embodiment of the present application, Figure 4 and Figure 5 As shown, the oil guide strip assembly 3 further includes a connecting side panel 33 located outside the first side panel 11, and an oil guide side panel 34 located below the connecting side panel 33 for directing grease from the corner between the front panel 10 and the first side panel 11 to the oil screen 4. Preferably, the oil guide side panel 34 is integrally formed with the connecting side panel 33 and is formed by bending the bottom of the connecting side panel 33 toward the interior of the range hood.
[0035] Furthermore, since the oil net 4 is in a relatively central position, in order to better guide the grease from the corner of the front plate 10 and the first side plate 11, the oil guide side plate 34 is constructed to gradually lower from front to back in the depth direction of the oil fume suction; in the width direction of the oil fume suction, the oil guide side plate is constructed to gradually lower from both sides to the middle.
[0036] According to an exemplary embodiment of the present application, Figure 5 As shown, the oil-deflecting side plate 34 includes a first side portion 341 and a second side portion 342 connected along the depth of the range hood. The first side portion 341 and the second side portion 342 are configured to gradually descend toward their connection; the vertical projection of the lowest point of the connection falls on the oil screen 4. As a result, grease that lands anywhere on the oil-deflecting side plate 34 will first flow toward the connection, then converge at the lowest point of the connection, and ultimately land on the oil screen 4.
[0037] In an optional embodiment, in the depth direction of the range hood, the first side portion 341 is constructed to gradually descend from front to back, and the second side portion 342 is constructed to gradually descend from back to front; in the width direction of the range hood, the first side portion 341 and the second side portion 342 are constructed to gradually descend from both sides to the middle.
[0038] In an optional embodiment, the connecting plate 30 and the connecting side plate 34 are integrally formed, with the corners formed by bending the two together. This facilitates casting and molding during production. Furthermore, an oil-guiding transition portion is provided on the end of the first oil-guiding plate 31 near the oil-guiding side plate 34. This transition portion is provided because, after bending, a gap may exist between the first oil-guiding plate 31 and the oil-guiding side plate 34 in the width or height of the range hood, posing a risk of oil leakage.
[0039] According to an exemplary embodiment of the present application, a wiring channel (not shown) is provided at one end of the front panel 10 close to the second side panel 12. The wiring channel is located at the corner of the second side panel 12 and the front panel 10 and extends in the vertical direction. It can be used to connect the control panel of the smoke collecting chamber 2 and the wires of the fan in the fan housing 1. Figure 6 As shown, the first oil guide plate 31 has a convex bump 311 at one end near the wiring channel. The convex bump 311 is configured to direct grease from the wiring channel toward the first oil guide plate 31 and / or the second oil guide plate 32. Optionally, the convex bump 311 smoothly abuts the surface of the wiring channel. The convex bump 311 gradually descends toward the center along the width of the range hood and toward the rear along the depth of the range hood, thereby better directing grease toward the first oil guide plate 31 and / or the second oil guide plate 32.
[0040] According to an exemplary embodiment of the present application, Figure 3 and Figure 5 As shown, the second oil guide plate 32 is connected to the rear side of the first oil guide plate 31 and is bent downward, which is beneficial for guiding the grease on the first oil guide plate 31 to the oil net 4.
[0041] Preferably, the included angle between the second oil guide plate and the first oil guide plate is 90°-135°.
[0042] According to an exemplary embodiment of the present application, as shown in the figure, the connecting plate 30 is provided with a first connecting hole 301 fixedly connected to the front plate 10; the first oil guide plate 31 is provided with a second connecting hole 311 fixedly connected to the mounting plate 20, thereby the fan casing 1 and the smoke hood 2 are installed together through the connection between the first oil guide plate 31 and the mounting plate 20.
[0043] Furthermore, the mounting plate 20 is provided with mounting holes (not shown) at different positions along the depth direction of the range hood to adapt to fan casings 1 of different depths.
[0044] The components of different embodiments can be combined with each other in any feasible manner to achieve the purpose of this application.
[0045] 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.
