Description
Technical Field
[0001] The utility model relates to the technical field of kitchen appliances, in particular to a range hood. Background Art
[0002] The front panel of an existing range hood is usually long and large in area. It is inevitable that some of the small oil droplets in the smoke generated during the cooking process will not be sucked into the air inlet, but will be scattered and adhered to the front panel. If they are not cleaned in time, the small oil droplets will condense and solidify, providing attachment points for small oil droplets generated in the later cooking process. Over time, the small oil droplets will continue to gather and grow into oily spots, and after the oily spots are condensed into a solid state, they will be more firmly bonded to the front panel and are difficult to remove, affecting the user experience. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a range hood in order to overcome the defect in the prior art that the front panel of the range hood is prone to form oily convex spots which are difficult to remove.
[0004] The utility model solves the above technical problems through the following technical solutions:
[0005] A range hood comprises a smoke hood, which comprises a first air inlet and a front panel; at least one oil baffle structure is arranged on the front panel, and the oil baffle structure protrudes from the outer surface of the front panel by a predetermined height; the oil baffle structure is arranged on the front panel and is located on the flow path of the smoke before entering the first air inlet, and the extension direction of the oil baffle structure forms an angle with the flow path of the smoke entering the first air inlet; the two ends of the oil baffle structure have a height difference in the vertical direction.
[0006] In the present solution, an oil baffle structure is provided on the flow path of the flue gas entering the first air inlet on the front panel. Since the extension direction of the oil baffle structure forms an angle with the flow path of the flue gas entering the first air inlet, when the range hood is in operation, the flue gas flow flowing into the first air inlet will pass over the oil baffle structure in a non-parallel direction. The oil baffle structure protrudes from the outer surface of the front panel by a predetermined height, so that the oil baffle structure forms a blocking effect on the flue gas flow. Small oil droplets in the flue gas will be blocked by the oil baffle structure and retained on the surface of the oil baffle structure. Due to the setting of the oil baffle structure, the aggregation of small oil droplets is more concentrated. Compared with the planar structure of the front panel, the raised oil baffle structure has a stronger ability to capture small oil droplets. More small oil droplets will quickly gather into larger oil droplets on the oil baffle structure. Since there is a height difference between the two ends of the oil baffle structure in the vertical direction, under the action of gravity, larger oil droplets can slide down along the oil baffle structure before condensing, instead of adhering to the front panel. As a result, the situation in which small oil droplets on the front panel condense into oily protrusions will be improved, thereby enhancing the user experience.
[0007] Preferably, a projection of the oil-blocking structure in a direction perpendicular to the first air inlet at least partially covers the first air inlet.
[0008] In this solution, through the above-mentioned structural form, the degree of shielding of the oil baffle structure on the first air inlet is increased to capture more small oil droplets, while reducing the oil content in the smoke entering the smoke hood, thereby improving the overall oil precipitation rate of the range hood.
[0009] Preferably, the oil retaining structure protrudes from the outer surface of the front panel by a height h, 2mm≤h≤6mm.
[0010] In the present scheme, the oil baffle structure protrudes from the outer surface of the front panel in order to intercept small oil droplets in the flue gas, so the protruding height of the oil baffle structure cannot be too low; if the protruding height of the oil baffle structure is too high, the interference with the flue gas flow entering the first air inlet will be too great, affecting the normal inhalation of the flue gas, so it is more appropriate to set the protruding height of the oil baffle structure to 2mm-6mm.
[0011] Preferably, there are a plurality of the oil-blocking structures, and adjacent oil-blocking structures are spaced apart by a predetermined distance.
[0012] In this solution, the provision of multiple oil-blocking structures can block more small oil droplets; and adjacent oil-blocking structures are spaced at a predetermined distance, so that each oil-blocking structure can function without affecting each other.
[0013] Preferably, a plurality of the oil baffle structures are arranged in sequence on the flow path of the smoke before it enters the first air inlet.
[0014] In this solution, through the above-mentioned structural form, the flue gas can pass through multiple oil-blocking structures in sequence during the flow process. Even if some small oil droplets are not intercepted by the oil-blocking structure in front of the flue gas flow path, since there is also an oil-blocking structure at the rear of the flue gas flow path, the probability of the small oil droplets being intercepted is greatly increased. The distribution of the oil-blocking structure is more reasonable and efficient.
[0015] Preferably, the oil retaining structure is in a straight line or a curved line.
[0016] In this solution, the shape of the oil retaining structure can be set to a straight line shape for easy processing according to actual needs, or it can be set to a curved shape to increase the contact area with the small oil droplets.
[0017] Preferably, the smoke hood further comprises a second air inlet, the second air inlet is opened on the front panel, and the second air inlet is located above the oil baffle structure; along the length direction of the smoke hood, the first air inlet is arranged on both sides of the front panel.
[0018] In this solution, the second air inlet is located above the oil-blocking structure to form a forward suction of smoke, and the first air inlet is set on both sides of the front panel to form a lateral suction of smoke, thereby increasing the number of air inlets of the range hood and enriching the opening positions of the air inlets to form an all-round suction of smoke. When the amount of oil smoke during cooking is large, the smoke cannot all enter the range hood from the second air inlet directly above the stove. Part of the smoke will flow horizontally along the front panel and enter the range hood from the first air inlet. The oil-blocking structure can prevent the diffusion of oil droplets in the smoke when the smoke passes by.
[0019] Preferably, the oil-blocking structure is formed by integrally stamping from the inner surface of the front panel to the outer surface of the front panel; or, the oil-blocking structure is connected to the outer surface of the front panel by a welding process; or, the oil-blocking structure is detachably connected to the outer surface of the front panel.
[0020] In this solution, the oil baffle structure can be stamped integrally with the front panel, which has a stronger integrity with the front panel; it can also be welded to the outer surface of the front panel, which has a simple process; it can also be detachably connected to the outer surface of the front panel, and the oil baffle structure can be installed or removed according to actual needs, and the oil baffle structure is convenient for cleaning and maintenance.
[0021] Preferably, the plane where the front panel is located forms an angle with the vertical direction.
[0022] In this solution, the plane where the front panel is located forms an angle with the vertical direction, so that the front panel is set at an angle. The front panel has a projection in the horizontal plane, which is convenient for directly shielding the smoke generated directly below the front panel during cooking and sucking it into the smoke collection hood.
[0023] Preferably, an oil receiving box is connected to the bottom of the front panel, and the opening of the oil receiving box faces the lower end of the oil retaining structure in the vertical direction.
[0024] In this solution, through the above-mentioned structural form, after the oil droplets slide down along the oil baffle structure, they can drip into the oil receiving box at the lower end of the oil baffle structure to complete unified collection.
[0025] The positive and progressive effects of the utility model are:
[0026] In the utility model, an oil baffle structure is provided on the flow path of the smoke entering the first air inlet on the front panel. Since the extension direction of the oil baffle structure forms an angle with the flow path of the smoke entering the first air inlet, when the range hood is in operation, the smoke flow flowing into the first air inlet will pass over the oil baffle structure in a non-parallel direction. The oil baffle structure protrudes from the outer surface of the front panel by a predetermined height, so that the oil baffle structure forms a blocking effect on the smoke flow. Small oil droplets in the smoke will be blocked by the oil baffle structure and retained on the surface of the oil baffle structure. Due to the setting of the oil baffle structure, the aggregation of small oil droplets is more concentrated. Compared with the planar structure of the front panel, the raised oil baffle structure has a stronger ability to capture small oil droplets. More small oil droplets will quickly gather into larger oil droplets on the oil baffle structure. Since the two ends of the oil baffle structure have a height difference in the vertical direction, under the action of gravity, larger oil droplets can slide down along the oil baffle structure before condensing, instead of adhering to the front panel. As a result, the situation in which small oil droplets on the front panel condense into oily protrusions will be improved, thereby enhancing the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.
[0042] like Figure 1-Figure 4 As shown, the present embodiment provides a range hood, comprising a smoke hood 10, the smoke hood 10 comprising a first air inlet 11 and a front panel 13; at least one oil baffle structure 14 is provided on the front panel 13, and the oil baffle structure 14 protrudes from the outer surface of the front panel 13 by a predetermined height; the oil baffle structure 14 is provided on the front panel 13, and is located on the flow path L before the smoke enters the first air inlet 11, and the extension direction of the oil baffle structure 14 forms an angle with the flow path L of the smoke entering the first air inlet 11; the two ends of the oil baffle structure 14 have a height difference in the vertical direction Z.
[0043] An oil-blocking structure 14 is provided on the flow path L of the smoke entering the first air inlet 11 on the front panel 13. Since the extension direction of the oil-blocking structure 14 forms an angle with the flow path L of the smoke entering the first air inlet 11, when the range hood is in operation, the smoke flow flowing into the first air inlet 11 will pass over the oil-blocking structure 14 in a non-parallel direction. The oil-blocking structure 14 protrudes from the outer surface of the front panel 13 by a predetermined height, so that the oil-blocking structure 14 forms a blocking effect on the smoke flow. Small oil droplets in the smoke will be blocked by the oil-blocking structure 14 and retained on the surface of the oil-blocking structure 14. The setting of the oil-blocking structure 14 makes the gathering of small oil droplets more concentrated. Compared with the planar structure of the front panel 13, the raised oil-blocking structure 14 has a stronger ability to capture small oil droplets. More small oil droplets will quickly gather into larger oil droplets on the oil-blocking structure 14. Because the two ends of the oil-blocking structure 14 have a height difference in the vertical direction Z, under the action of gravity, larger oil droplets can slide down along the oil-blocking structure 14 before condensing, instead of adhering to the front panel 13. Therefore, the situation in which small oil droplets on the front panel 13 condense into oil stains will be improved, thereby improving the user experience.
[0044] In addition, providing the oil retaining structure 14 on the front panel 13 also correspondingly increases the structural strength and rigidity of the front panel 13 and improves the high temperature resistance of the front panel 13; and when the range hood is running, the vibration of the front panel 13 caused by the smoke flow will also be reduced, thereby reducing noise.
[0045] The height of the oil retaining structure 14 protruding from the outer surface of the front panel 13 is h, and in this embodiment h=6mm. The oil retaining structure 14 protrudes from the outer surface of the front panel 13 to intercept small oil droplets in the smoke, so the height of the oil retaining structure 14 cannot be too low to ensure the interception of small oil droplets.
[0046] However, if the protruding height of the oil retaining structure 14 is too high, the interference with the flue gas flow entering the first air inlet 11 will be great, which may affect the normal inhalation of the flue gas. Therefore, in other optional embodiments, h=2mm can also be set.
[0047] In other optional embodiments, h=4 mm may be set to balance the need for the oil retaining structure 14 to intercept small oil droplets in the flue gas and the need to prevent the oil retaining structure 14 from interfering with normal inhalation of the flue gas.
[0048] Of course, in practice, the specific value of h is not limited to the above three examples, and any value between 2 mm and 6 mm is acceptable.
[0049] Furthermore, the projection of the oil baffle structure 14 in a direction perpendicular to the first air inlet 11 at least partially covers the first air inlet 11, so as to increase the degree of shielding of the first air inlet 11 by the oil baffle structure 14, capture more small oil droplets, and at the same time reduce the oil content in the smoke entering the smoke hood, thereby improving the overall oil precipitation rate of the range hood.
[0050] like Figure 4 As shown, due to the limitation of the structural arrangement space, in this embodiment, the projection of the oil retaining structure 14 in the direction perpendicular to the first air inlet 11 is selected to partially cover the first air inlet 11. In other optional embodiments, the projection of the oil retaining structure 14 in the direction perpendicular to the first air inlet 11 can also be selected to completely cover the first air inlet 11 if the arrangement space allows.
[0051] Specifically, the oil retaining structure 14 in this embodiment is in a straight line shape to facilitate processing; in other optional implementations, the shape of the oil retaining structure 14 can also be set to a curved shape according to actual needs to increase the contact area between the oil retaining structure 14 and the small oil droplets.
[0052] In addition, in this embodiment, the oil retaining structure 14 is formed by integrally stamping from the inner surface of the front panel 13 to the outer surface of the front panel 13, that is, the oil retaining structure 14 forms a groove on the inner surface of the front panel 13 to form a rib structure on the outer surface of the front panel 13. The integral stamping process is mature and simple to manufacture. The manufacture of the front panel 13 and the manufacture of the oil retaining structure 14 can be completed synchronously in one piece, and the oil retaining structure 14 and the front panel 13 have a stronger integrity and are more beautiful.
[0053] In other optional embodiments, in order to fix the oil baffle structure 14 on the front panel 13, the oil baffle structure 14 can also be manufactured separately, and the oil baffle structure 14 can be connected to the outer surface of the front panel 13 through a welding process; in addition, the oil baffle structure 14 can also be detachably connected to the outer surface of the front panel 13 by means of screws, clamping, etc., so that the oil baffle structure 14 can be installed or removed according to actual needs, and the oil baffle structure 14 can be cleaned and maintained conveniently.
[0054] In order to block more small oil droplets, in this embodiment, the number of oil blocking structures 14 is preferably multiple, and adjacent oil blocking structures 14 are spaced a predetermined distance apart, so that each oil blocking structure 14 can function without affecting each other. Of course, in other optional embodiments, the number of oil blocking structures 14 can also be set to one.
[0055] Furthermore, in the present embodiment, a plurality of oil baffle structures 14 are arranged in sequence on the flow path L before the flue gas enters the first air inlet 11, so that the flue gas can pass through the plurality of oil baffle structures 14 in sequence during the flow. Even if some small oil droplets are not intercepted by the oil baffle structures 14 in front of the flue gas flow path L, since an oil baffle structure 14 is also provided at the rear of the flue gas flow path L, the probability that the small oil droplets will eventually be intercepted is greatly increased. The distribution of the oil baffle structures 14 is thus more reasonable and efficient.
[0056] In other optional implementations, the specific layout position relationship between the multiple oil retaining structures 14 can be adjusted differently from that of this embodiment according to actual conditions.
[0057] like Figure 3 and Figure 4 As shown, in this embodiment, the smoke hood 10 also includes a second air inlet 12, which is opened on the front panel 13 and located above the oil baffle structure 14; along the length direction X of the smoke hood 10, the first air inlet 11 is arranged on both sides of the front panel 13.
[0058] Specifically, there are two second air inlets 12 arranged in a row in the length direction X of the smoke hood 10; there are two first air inlets 11, which are respectively arranged on both sides of the front panel 13. The second air inlet 12 is located above the oil retaining structure 14 to form a forward suction of the smoke, and the first air inlet 11 is arranged on both sides of the front panel 13 to form a lateral suction of the smoke, thereby increasing the number of air inlets of the range hood and enriching the opening positions of the air inlets, so as to form an all-round suction of the smoke.
[0059] When the amount of oil smoke is large during cooking, the smoke cannot all enter the range hood from the second air inlet 12 directly above the cooker, and part of the smoke will flow horizontally (roughly along the length direction X of the smoke hood 10) along the front panel 13 and enter the range hood from the first air inlet 11 (see Figure 3 , Figure 3 The flow path L) of the flue gas entering the first air inlet 11 is schematically indicated.
[0060] In this embodiment, based on the setting position of the first air inlet 11 and the flow path L of the smoke entering the first air inlet 11 caused by it, the oil blocking structure 14 is selected to extend in the up-down direction on the front panel 13 to form an angle with the flow path L of the smoke entering the first air inlet 11, thereby hindering the diffusion of oil droplets in the smoke when the smoke passes by. And because the oil blocking structure 14 extends in the up-down direction, the two ends of the oil blocking structure 14 must have a height difference in the vertical direction Z, so as to facilitate the small oil droplets to slide off as soon as possible after intercepting them.
[0061] In order to ensure the effect of capturing small oil droplets, the multiple oil baffle structures 14 in this embodiment extend roughly from below the second air inlet 12 to the bottom position of the front panel 13, and the multiple oil baffle structures 14 are arranged in a row on the front panel 13 along the length direction X of the smoke hood 10.
[0062] It can be understood that the extension direction of the oil retaining structure 14 forms an angle with the flow path L of the smoke entering the first air inlet 11 in order to avoid the extension direction of the oil retaining structure 14 being parallel to the flow path L of the smoke entering the first air inlet 11, so that the oil retaining structure 14 cannot form a blocking effect on the smoke airflow (small oil droplets in it). Therefore, the extension of the oil retaining structure 14 in the up-down direction is not the only option. In other optional embodiments, the extension direction of the oil retaining structure 14 can also form a certain angle with the up-down direction, so that the oil retaining structure 14 can also be set obliquely. The extension length of the oil retaining structure 14 can also be adaptively adjusted according to actual conditions.
[0063] In addition, since the setting position of the oil-blocking structure 14 depends on the setting position of the first air inlet 11 and the flow path L of the smoke entering the first air inlet 11 caused by the setting position, when the setting position of the first air inlet 11 changes, the setting position and extension direction of the oil-blocking structure 14 will be adjusted accordingly. For example, in other optional embodiments, when the first air inlet 11 is opened at the position of the second air inlet 12 as in the present embodiment, the extension direction of the oil-blocking structure 14 can be adjusted accordingly to extend roughly along the length direction X of the smoke hood 10 (slightly tilted so that the two ends of the oil-blocking structure 14 have a height difference in the vertical direction Z), which can also enable the oil-blocking structure 14 to block the smoke flow entering the first air inlet 11 and capture small oil droplets therein.
[0064] Furthermore, if Figure 1 As shown, the plane where the front panel 13 is located forms an angle with the vertical direction Z, so that the front panel 13 is set tilted. The front panel 13 has a projection in the horizontal plane, which is convenient for directly shielding the smoke generated directly below the front panel 13 during cooking and sucking it into the smoke collection hood 10.
[0065] Furthermore, an oil collecting box 15 is connected to the bottom of the front panel 13, and the opening of the oil collecting box 15 faces the lower end of the oil retaining structure 14 in the vertical direction Z. Therefore, after the oil droplets slide down along the oil retaining structure 14, they can drip into the oil collecting box 15 at the lower end of the oil retaining structure 14 to complete unified collection.
[0066] Of course, when there are multiple oil retaining structures 14, the oil receiving box 15 can be provided with multiple openings corresponding to each other. In this embodiment, the oil receiving box 15 is selected to be provided with a long through opening in the length direction X of the range hood for easy manufacturing.
[0067] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
