Description

Technical Field

[0001] The utility model relates to a range hood, in particular to a power board installation structure of the range hood. Background Art

[0002] At present, the installation method of the power board of the range hood is generally to first fix the power board to the electric control box with screws, and then fix the electric control box to the top plate of the range hood with screws. The installation process requires the use of multiple screws, which is low in production efficiency and inconvenient for maintenance. In addition, if the torque of the screws used to fix the power board is not used properly, the power board may be easily damaged, which increases the production cost. Therefore, the existing power board installation structure of the range hood needs to be further improved. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a power board installation structure of a range hood which is easy to install and disassemble and has high reliability in view of the above-mentioned existing technical status.

[0004] The technical solution adopted by the utility model to solve the above-mentioned technical problems is: a power board installation structure for a range hood, including an electric control box and a power board installed on the electric control box, characterized in that: a buckle is provided on one side of the electric control box, and a spring buckle is provided on the other side of the electric control box, one side of the power board is snapped into the buckle on the corresponding side, and the power board is rotated downward around the side where the buckle is located and the other side of the power board is snapped into the spring buckle.

[0006] In order to ensure that the power board can be reliably limited on the electric control box, a first limiting rib for limiting the power board is protruding inwardly on the inner wall of the electric control box below the buckle, and a second limiting rib for limiting the power board is protruding inwardly on the inner wall of the spring buckle.

[0007] In order to make the spring buckle have better rebound performance and facilitate the power board to be inserted into the spring buckle, U-shaped grooves for improving the elasticity of the spring buckle are opened on the left and right sides of the spring buckle.

[0008] In order to facilitate the power board to be inserted into the spring buckle, the top of the spring buckle has a guiding inclined surface that slopes downward from the outside to the inside.

[0009] In order to effectively dissipate heat for the power board, a heat dissipation slot is provided at the bottom of the electric control box, and the heat dissipation slot is correspondingly arranged below the heating element of the power board.

[0010] In order to install the assembled electric control box and power board on the chassis, a fixing buckle for fixing to the chassis is extended downward from the outer bottom of the electric control box.

[0011] In order to prevent the power board from being disengaged from the buckle and the spring buckle, the buckle and the power board are in interference fit, and the spring buckle and the power board are in interference fit.

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] like Figures 1 to 6As shown, the power board installation structure of the range hood of this embodiment includes an electric control box 1 and a power board 2 installed on the electric control box 1, and the electric control box 1 and the power board 2 are both rectangular. A buckle 11 is provided on the long side of one side of the electric control box 1, and there are three buckles 11 and they are spaced apart along the length direction of the side. Spring buckles 12 are provided on the other three sides of the electric control box 1. In this embodiment, there are two spring buckles 12 on the long side and one spring buckle 12 on the short side. U-shaped grooves 15 are provided on the left and right sides of the spring buckle 12. The U-shaped grooves 15 are used to increase the elasticity of the spring buckle 12, so that the power board 2 can be easily inserted into the spring buckle 12. The top of the spring buckle 12 has a guide inclined surface 121 that is inclined downward from the outside to the inside, and the guide inclined surface 121 guides the power board 2 to ensure that the power board 2 can be smoothly inserted into the spring buckle 12. A first limiting rib 13 for limiting the power board 2 is protruding inwardly on the inner wall of the electric control box 1 below the buckle 11, and a second limiting rib 14 for limiting the power board 2 is protruding inwardly on the inner wall of the spring buckle 12. The first limiting rib 13 and the second limiting rib 14 contact and position the power board 2.

[0023] When installing the power board 1, first put one side of the power board 2 into the buckle 11 on the corresponding side, and contact and position it with the first limiting rib 13. Then, the power board 2 rotates downward around the side where the buckle 11 is located, and the remaining three sides of the power board 2 are snapped into the spring buckle 12. When the other three sides of the power board 2 contact the spring buckle 12, they first contact the guide bevel 121 on the spring buckle 12. At this time, the spring buckle 12 is pried open by hand so that the side of the power board 2 can be smoothly snapped into the spring buckle 12. After the power board 2 is installed in place, the four sides of the power board 2 are contacted and positioned with the first limiting rib 13 and the second limiting rib 14, which can reduce the contact surface between the side of the power board 2 and the electric control box 1, and prevent the size of the electric control box 1 from fluctuating and causing the power board 2 to fail to be installed. After the power board 2 is bent into place, the spring buckles 12 all return to their original state to prevent the power board 2 from loosening and falling off.

[0024] like Figure 3 As shown, after installation, the buckle 11 and the power board 2 are in interference fit, and the interference amount A is 1.5-3mm; the spring buckle 12 and the power board 2 are in interference fit, and the interference amount B is 1.5-3mm.

[0025] like Figure 6 As shown, a heat dissipation slot 16 is provided at the bottom of the electric control box 1 , and the heat dissipation slot 16 is correspondingly arranged below the heating element of the power board 2 . The heat dissipation slot 16 is used to accelerate the heat dissipation of the power board 1 and improve the reliability of the power board 1 .

[0026] like Figure 7 As shown, a fixing buckle 17 extends downward from the outer bottom of the electric control box 1. After the power board 1 is installed on the electric control box 2, the entire assembly is fixed on the chassis 3, one end of which is fixed with the fixing buckle 17 and the other end can be fixed with screws.

[0027] In the specification and claims of the present invention, terms indicating directions, such as "front", "rear", "up", "down", "left", "right", "side", "top", "bottom", etc., are used to describe various exemplary structural parts and elements of the present invention, but these terms are used here only for the purpose of convenience of description and are determined based on the exemplary orientations shown in the accompanying 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.
