Technical Field

[0001] The utility model relates to the technical field of range hoods, in particular to a bracket mounting structure of a rectifier plate of a range hood and the range hood. Background Art

[0002] A range hood is a kitchen appliance that purifies the kitchen environment. Generally, range hoods include top suction type and side suction type, and top suction type range hoods are more and more widely used due to their advantages such as being neat, light, and taking up little space. Top suction type range hoods generally include a smoke hood, a fan housing located on the smoke hood, and a centrifugal fan installed in the fan housing. For example, a Chinese invention patent application with application number CN200910096759.3 (authorization announcement number CN101514823B) discloses a range hood with a smoke guide plate, including a body, a smoke hood, and a smoke guide plate. An air inlet is provided at the bottom of the smoke hood, and a smoke guide plate (also called a rectifier plate) is arranged opposite to the air inlet and maintains a predetermined distance from the smoke hood, thereby forming a smoke channel for the smoke to pass through between the smoke guide plate and the smoke hood.

[0003] The rectifier plate and the smoke hood are generally installed together by a bracket and a hook. The hook is arranged on the back of the smoke hood and the bracket is arranged on the smoke hood. However, the existing bracket installation structure has many parts and components, and since most of them are zinc alloy or aluminum alloy parts, the cost is relatively high. Generally, the top plate or the back plate of the smoke hood needs to be removed for maintenance during disassembly and assembly, which is not convenient for cleaning or after-sales service.

[0004] Therefore, the mounting structure of the bracket of the rectifier plate of the existing range hood needs to be further improved. Utility Model Content

[0005] The first technical problem to be solved by the utility model is to provide a mounting structure of a bracket for a rectifier plate of a range hood which can effectively simplify the structure and mounting process of the bracket in view of the current status of the prior art.

[0012] In order to conveniently pass the first plate through the mounting slot on the smoke collecting hood, the thickness of the first plate is consistent with the slot width of the mounting slot. The first plate is a square plate, and the length of the square plate is consistent with the length of the mounting slot.

[0013] In order to save materials and improve aesthetics, the width of the second plate gradually decreases from the position where it is connected to the first plate to the end position away from the first plate.

[0014] Considering that a certain distance needs to be reserved between the rectifying plate and the smoke collecting hood, the hanging shaft is connected to the end position of the second plate away from the first plate.

[0015] In order to save costs, the hanging shaft is a step screw, and the second plate is provided with a screw hole connected to the step screw.

[0016] In order to ensure the fixing reliability between the hanging bracket and the smoke collecting hood, there are at least three through holes on the first plate, and the through holes are not arranged on the same straight line.

[0017] As an improvement, there are two hanging racks, which are arranged on the rear side wall of the smoke collecting hood at intervals along the left-right direction.

[0018] As an improvement, the hanging shafts on the two hanging racks are respectively arranged on two opposite side walls of the second plates of the two hanging racks.

[0019] As an improvement, the connecting piece is a screw or a rivet.

[0021] Compared with the prior art, the advantages of the utility model are: it adopts a simple L-shaped bracket, and after tilting at a certain angle, the first plate can be inserted into the back of the wall of the smoke hood and then fixed by a connecting piece. The L-shaped bracket has a simple structure and can be directly produced by sheet metal stamping. The parts are simple and low-cost, which is convenient for the popularization of such machines. At the same time, when servicing, repairing or cleaning, connecting pieces (such as screws or rivets) can be directly installed in the cavity of the smoke hood. There is no need to lift the machine hung on the wall, nor is there any need to remove the top plate or back plate, which reduces the time for service and cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions are only used as explanations and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0030] Figure 1-Figure 6The invention shows a preferred embodiment of the range hood and a bracket mounting structure of the rectifier plate of the range hood. The range hood includes a housing and a centrifugal fan arranged in the housing. The housing generally includes a fan frame and a fume hood 10 arranged at the bottom of the fan frame. The inner cavity of the fan frame is connected to the inner cavity of the fume hood 10. An air inlet 100 is provided on the front side wall of the fume hood 10, and external smoke can enter the fume hood 10 through the air inlet 100. The centrifugal fan is arranged in the fan frame. When the centrifugal fan is running, negative pressure is generated, and external oil smoke can be sucked into the fume hood 10 through the air inlet 100. An oil net is also provided at the air inlet 100 of the fume hood 10 for filtering oil smoke. An oil cup 50 is provided at the bottom of the fume hood 10. The oil cup 50 is in the shape of a long strip extending left and right, and is used to receive the oil stains flowing down from the fume hood 10. The smoke hood 10 is provided with a rectifying plate 40 corresponding to the lower part of the air inlet 100, and the rectifying plate 40 is basically arranged horizontally. The front part of the rectifying plate 40 is connected to the smoke hood 10 through two groups of snap-fastening components arranged at intervals on the left and right, and the rear part is connected to the smoke hood 10 through two hook 41 components arranged at intervals on the left and right. The snap-fastening component generally includes a snap-fastening member 13 arranged on the smoke hood 10 and a snap-fastening seat 42 arranged on the back of the rectifying plate 40. The snap-fastening component can adopt various snap-fastening components in the prior art, which will not be described here.

[0031] See also Figure 3-Figure 5 The smoke hood 10 is also provided with a hanger, which includes a hanger body 21 and a hanger shaft 22 provided on the hanger body 21, and the hanger shaft 22 extends in the left-right direction. A hook 41 extending backward is provided at the rear of the back of the rectifying plate 40, and when installed, the hook 41 of the rectifying part can be hung on the hanger shaft 22 of the smoke hood 10. The above-mentioned hook 41 and the hanger together constitute the above-mentioned hook 41 assembly.

[0032] See also Figure 3 An important inventive point of the present embodiment lies in the mounting structure between the bracket and the smoke hood 10. Specifically, a mounting groove 11 extending from the front to the back and a through hole 12 arranged adjacent to the mounting groove 11 are provided on the rear side wall of the smoke hood 10. The mounting groove 11 basically extends vertically. There are three through holes 12, and the connecting line between the positions of the three through holes 12 is a triangle.

[0033] See also Figure 4The main body 21 of the bracket is L-shaped as a whole, and includes a first plate 211 and a second plate 212 set at an angle, and the hanging shaft 22 is connected to the second plate 212. Specifically, considering that a certain distance needs to be reserved between the rectifying plate 40 and the smoke hood 10, the hanging shaft 22 is located at the end position of the second plate 212 away from the first plate 211. The above-mentioned first plate 211 is perpendicular to the second plate 212. In order to save costs, the hanging shaft 22 of this embodiment is a step screw, wherein a screw hole 2120 connected to the step screw is opened on the second plate 212. After the step screw is connected in place, the optical axis portion of the step screw can be in contact with the support of the hook 41 of the rectifying plate 40, and the head size of the step screw is larger than the size of the optical axis portion, which can limit the hook 41 from falling off.

[0034] During installation, the bracket body 21 can be slightly tilted at a certain angle so that the first plate 211 of the bracket body 21 passes through the installation groove 11 from the front of the smoke hood 10 and then the bracket body 21 is straightened, so that the first plate 211 is attached to the back of the area where the through hole 12 on the wall of the smoke hood 10 is located. After the bracket body 21 is straightened, the connecting holes 2110 (three corresponding holes are also set) on the first plate 211 correspond one by one to the three through holes 12 on the wall of the smoke hood 10, and then, the connecting parts 30 (screws or rivets can be used) are installed to fix the bracket relative to the smoke hood 10.

[0035] In order to facilitate the first plate 211 to pass through the installation slot 11 on the smoke hood 10, the thickness of the first plate 211 of this embodiment is consistent with the slot width of the installation slot 11. Specifically, the first plate 211 is a square plate, and the length of the square plate is consistent with the length of the installation slot 11. Therefore, after the hanger body 21 is installed in place, the installation slot 11 can be fully filled without gaps, ensuring aesthetics. In order to further save materials and aesthetics, the width of the second plate 212 of the hanger body 21 gradually decreases from the position where it is connected to the first plate 211 to the end position away from the first plate 211.

[0036] See also Figure 2 and Figure 3 In this embodiment, there are two hangers on the smoke hood 10, and the two hangers are arranged on the rear side wall of the smoke hood 10 at intervals along the left and right directions. Correspondingly, there are also two hooks 41 on the rectifying plate 40, which correspond to the two hangers one by one. The hanging shafts 22 on the two hangers are respectively arranged on the two opposite side walls of the second plates 212 of the two hangers.

[0037] The present embodiment adopts a simple L-shaped bracket. After tilting at a certain angle, the first plate 211 can be inserted into the back of the wall of the smoke hood 10 and then fixed by the connecting piece 30. The L-shaped bracket has a simple structure and can be directly produced by sheet metal stamping. The parts are simple and low-cost, which is convenient for the popularization of such machines. At the same time, when servicing, repairing or cleaning, the connecting piece 30 (such as screws or rivets) can be directly installed in the cavity of the smoke hood 10. There is no need to lift the machine hung on the wall or remove the top plate or the back plate, thereby reducing the time for servicing and cleaning.
