Description

Technical Field

[0001] The utility model relates to the technical field of range hoods, in particular to an installation structure of a smoke baffle of a range hood and a range hood. Background Art

[0002] A range hood is a kitchen appliance for purifying the kitchen environment. The range hood works based on the principle of fluid dynamics, sucks and exhausts cooking fumes through a centrifugal fan installed inside the range hood, and filters some grease particles using a filter screen. The centrifugal fan includes a volute, an impeller installed in the volute, and a motor that drives the impeller to rotate. When the impeller rotates, a negative pressure suction force is generated at the center of the fan, sucking the cooking fumes below the range hood into the fan, and after being accelerated by the fan, they are collected by the volute and guided to be discharged outdoors.

[0003] Generally, range hoods include top-suction type and side-suction type. The side-suction type range hood utilizes the principle of eddy current wind pressure to absorb most of the cooking fumes that are relatively close to the cooking range in an arc shape, which can reduce the adverse effects on human health, and the power source is relatively close to the cooking range, and basically will not reduce the suction effect of the power source. To increase the smoke gathering range and improve the smoke suction effect, a flip-up smoke baffle is usually provided on the front panel. Among them, most of the smoke baffles of the near-suction type range hoods are made of glass. A bracket is bonded to the smoke baffle, and the bracket and the rocker of the motion mechanism are fixed with screws. Usually, two hole structures need to be designed on the rocker and the bracket to facilitate the screws to pass through. The applicant found that, in actual design, in order to facilitate the screws to pass through, the diameter of the through hole on the rocker is always larger than the diameter of the flanging hole on the bracket. The ideal installation state is as Figure 1 shown, the center of the hole on the rocker is aligned with the center of the hole on the bracket, but in actual installation, the situation where the holes are not completely aligned often occurs. Two extreme states are as Figure 2 and Figure 3 shown. In the above two cases, since the length of the smoke baffle is much larger than the size of the hole diameter, this tiny offset is magnified and the phenomenon shown at the end of the smoke baffle is that the end of the smoke baffle bulges or sags, that is, there is a step difference between the upper panel and the lower panel, resulting in quality problems.

[0004] Therefore, the installation structure of the smoke baffle of the existing range hood still needs to be further improved. Summary of the Utility Model

[0005] The first technical problem to be solved by the utility model is to provide an installation structure of a smoke baffle of a range hood that can effectively improve the step difference problem caused by the offset of the mounting hole positions of the bracket of the smoke baffle when the smoke baffle is in the closed state, in view of the current situation of the prior art.

[0006] The second technical problem to be solved by the utility model is to provide a range hood using the above-mentioned smoke baffle installation structure in view of the current status of the prior art.

[0007] The technical solution adopted by the utility model to solve the above-mentioned first technical problem is: a smoke baffle installation structure of a range hood, comprising:

[0008] A smoke baffle having a connecting bracket on the back thereof;

[0009] A rocker, a first end of which is rotatably connected to the body of the range hood, and a second end of which is connected to the connecting bracket;

[0010] The connecting bracket includes a mounting plate for being attached to the back side of the smoke shield and a connecting plate extending from the mounting plate toward a side away from the smoke shield, the connecting plate is provided with at least three non-collinear first connecting holes, the rocker is provided with at least three second connecting holes respectively corresponding to the first connecting holes, the first connecting holes on the connecting plate correspond one-to-one to the second connecting holes on the rocker and are connected by fasteners.

[0011] In order to facilitate processing and ensure the strength of the connecting bracket, the connecting plate and the mounting plate are integrated.

[0012] As an improvement, the connecting plate extends vertically and is perpendicular to the mounting plate.

[0013] Generally speaking, setting three connecting holes can effectively reduce the offset problem after the connection between the connecting plate and the rocker. In order to reduce the processing cost, there are three first connecting holes on the connecting plate and there are also three corresponding second connecting holes on the rocker. Among them, the connecting line between the positions of the three first connecting holes on the connecting plate is a right triangle, and the connecting line between the positions of the three second connecting holes on the rocker is also a right triangle.

[0014] In order to further improve the step difference problem of the smoke shield in the closed state caused by the offset of the mounting hole position of the smoke shield bracket, when the connecting plate and the second end of the rocker are connected in place, the edge of the second end of the rocker abuts against the mounting plate. The edge of the second end of the rocker abuts against the mounting plate, which can limit the offset of the rocker relative to the connecting bracket in a certain direction, thereby further improving the step difference problem of the smoke shield in the closed state caused by the offset of the mounting hole position of the smoke shield bracket to a certain extent.

[0015] In order to ensure that the mounting plate has the effect of limiting the displacement of the rocker relative to the connecting bracket, the edge of the second end of the rocker is a straight edge structure parallel to the plane where the mounting plate is located, and the straight edge structure abuts against the mounting plate. The above structural design makes the edge of the second end of the rocker and the mounting plate in line contact, which improves the effect of limiting the displacement of the rocker and ensures the reliability and stability of the connection between the rocker and the connecting bracket.

[0016] As an improvement, there are two connecting brackets on the back of the smoke deflector, which are arranged in sequence along the length direction of the smoke deflector, and there are also two corresponding rockers.

[0017] In order to avoid interference, the two connecting brackets are respectively arranged adjacent to the two ends of the smoke baffle in the length direction.

[0018] As an improvement, the smoke baffle is a glass plate, and the connecting bracket is connected to the back side of the smoke baffle by gluing.

[0019] The technical solution adopted by the utility model to solve the above-mentioned second technical problem is: a range hood, including a casing and a smoke baffle, the casing is provided with an air inlet, the smoke baffle is rotatably arranged on the casing and can open and close the air inlet, and also includes the smoke baffle mounting structure of the above-mentioned range hood.

[0020] Compared with the prior art, the advantages of the utility model are as follows: since the connecting plate of the connecting bracket and the second end of the rocker arm are connected by fasteners by opening at least three connecting holes, and at least three connecting holes are non-collinearly arranged, the shaking or offset between the connecting plate and the rocker arm can be effectively reduced, and the step difference problem of the smoke shield in the closed state caused by the offset of the bracket installation hole of the smoke shield can be effectively improved, thereby improving the user experience.

[0027] The present invention will be further described in detail below in conjunction with the embodiments with reference to the accompanying drawings.

However, these terms are used herein only for the purpose of convenience of description and are determined based on the exemplary orientations shown in the drawings. Since the embodiments disclosed by the present invention can be arranged in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to the directions opposite to or consistent with the direction of gravity.

[0029] Figures 3 - 6 Shows the smoke baffle mounting structure of the range hood of the present invention and a preferred embodiment of the range hood. The range hood includes a housing and a centrifugal fan disposed within the housing. The housing generally includes a fan frame 11 and a smoke collecting hood 12 disposed at the bottom of the fan frame 11. The inner cavity of the fan frame 11 is in communication with the inner cavity of the smoke collecting hood 12. An air inlet is formed on the front side wall of the smoke collecting hood 12, and external smoke can enter the smoke collecting hood 12 through the air inlet. The centrifugal fan is disposed within the fan frame 11. When the centrifugal fan operates, a negative pressure is generated, and external cooking fumes can be sucked into the smoke collecting hood 12 through the air inlet. A smoke baffle 13 that can deflect forward and backward relative to the smoke collecting hood 12 is further disposed at the front of the smoke collecting hood 12. The smoke baffle 13 is rotatably connected to the main body of the smoke collecting hood 12 through a rocker 30, and specifically, it can be driven by a motion mechanism to deflect forward to open the above-mentioned air inlet and deflect backward to block and close the above-mentioned air inlet. Specifically, the motion mechanism for driving the movement of the smoke baffle 13 can adopt a conventional link motion mechanism or an electric push rod 33 in the prior art, which will not be elaborated herein. As Figure 3 Shows that the motion mechanism adopts an electric push rod 33, and the end of the telescopic rod of the electric push rod 33 is rotatably connected to one of the rockers 30.

[0030] See Figure 4 , the smoke baffle mounting structure includes a smoke baffle 13, a connecting bracket 20, and a rocker 30. The connecting bracket 20 is connected to the back surface of the smoke baffle 13. Among them, there are two connecting brackets 20, which are respectively disposed at two end positions adjacent to the length direction of the back surface of the smoke baffle 13. The two connecting brackets 20 are correspondingly connected to the two rockers 30.

[0031] The rocker 30 is a bent C-shaped plate structure as a whole, and its first end 31 is rotatably connected to the body of the range hood, and the second end 32 is connected to the connecting bracket 20. The connecting bracket 20 includes a mounting plate 21 and a connecting plate 22, and the connecting plate 22 is perpendicular to the mounting plate 21. Specifically, the main body of the smoke baffle 13 is a glass plate, and the mounting plate 21 is connected to the back of the smoke baffle 13 by bonding, and the connecting plate 22 extends from the mounting plate 21 toward the side away from the smoke baffle 13. In order to facilitate processing and ensure the strength of the connecting bracket 20, the connecting plate 22 and the mounting plate 21 are an integral part, and can be specifically formed by stamping and bending on the base plate of the mounting plate 21.

[0032] The connecting plate 22 is provided with at least three non-collinear first connecting holes 220, and the rocker 30 is provided with at least three second connecting holes 320 corresponding to the first connecting holes 220. Figure 4 As shown, three first connection holes 220 are shown on the connection plate 22, and the line connecting the positions of the three first connection holes 220 on the connection plate 22 is a right triangle. Correspondingly, there are also three second connection holes 320 on the rocker 30, and the line connecting the positions of the three second connection holes 320 on the rocker 30 is also a right triangle. Each first connection hole 220 on the connection plate 22 corresponds to each second connection hole 320 on the rocker 30 one by one and both are connected by a fastener 40, and the fastener 40 can be a screw.

[0033] Since the connecting plate 22 of the connecting bracket 20 and the second end 32 of the rocker arm 30 are connected by fasteners 40 with at least three connecting holes, and at least three connecting holes are non-collinearly arranged, the shaking or offset between the connecting plate 22 and the rocker arm 30 can be effectively reduced, and the step difference problem of the smoke baffle 13 in the closed state caused by the offset of the bracket mounting hole position of the smoke baffle 13 can be effectively improved, thereby improving the user experience.

[0034] The edge of the second end 32 of the rocker 30 of this embodiment is a straight edge structure parallel to the plane where the mounting plate 21 is located. When the connecting plate 22 and the second end 32 of the rocker 30 are connected in place, the straight edge structure abuts against the mounting plate 21 (that is, abuts against the position where the root of the connecting plate 22 on the mounting plate 21 is located). The edge of the second end 32 of the rocker 30 abuts against the mounting plate 21, which can limit the deviation of the rocker 30 relative to the connecting bracket 20 in a certain direction, thereby further improving the step difference problem of the smoke baffle 13 in the closed state caused by the deviation of the bracket mounting hole position of the smoke baffle 13 to a certain extent.
