Description

Technical Field

[0001] This utility model relates to an embedded control box structure and a smoke hood. Background Technology

[0002] The power supply box is an important component of the range hood. It is usually installed on the casing of the range hood to facilitate maintenance and replacement during subsequent use. In order to prevent oil fumes and water vapor from entering the power supply box, the circuit board inside the box is usually sealed. Although this effectively solves the problem of water vapor entering, the heat released by the high-power components on the circuit board is difficult to dissipate, resulting in serious heat accumulation on the circuit board. If the range hood is turned on for a long time or multiple functions are used at the same time, the circuit board is prone to burnout.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned problems. We provide an embedded control box structure and a range hood, which solves the problem of heat accumulation and burnout of the circuit board.

[0005] To achieve the above objectives, this utility model provides an embedded control box structure, which includes a top cover, a bottom shell, and a heat sink plate distributed from top to bottom. The top cover and the bottom shell are connected to form a sealed mounting cavity. The heat sink plate is connected to the bottom shell cover and has a heat-conducting part extending into the mounting cavity. The top cover has an extension portion that extends laterally out of the bottom shell. The lower end of the extension portion has a wire-passing port, and the extension portion communicates with the mounting cavity.

[0006] In one or more embodiments, the top of the bottom shell is provided with an opening, and an annular recess is provided around the opening, with at least a portion of the cover connected to the annular recess.

[0007] In one or more embodiments, the faceplate is fixedly connected to the bottom shell by a first screw.

[0008] In one or more embodiments, the top of the bottom shell is provided with an annular outer edge around the outer peripheral wall, and mounting holes are provided on the annular outer edge.

[0009] In one or more embodiments, the heat sink is fixed to the bottom shell by a second screw, and the heat sink covers the bottom of the bottom shell.

[0010] This application also provides a range hood having the control box structure described in the above embodiments.

[0011] Compared with the prior art, the advantages of this utility model are: the control box adopts an embedded installation method, which avoids the control box being too exposed and thus affecting the appearance of the range hood. In addition, a heat sink is added, which uses the heat sink to conduct heat to the high-power components of the circuit board, and then dissipates the heat through the heat sink, which can effectively solve the problem of heat accumulation and poor heat dissipation of the circuit board.

[0014] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0015] Please refer to Figure 1-2 This utility model provides an embedded control box structure, which includes a top cover 1, a bottom shell 2, and a heat sink 3 distributed from top to bottom. The top cover 1 and the bottom shell 2 are connected to form a sealed mounting cavity for placing a circuit board. The heat sink 3 is connected to the bottom shell 2 and has a heat-conducting part 31 extending into the mounting cavity. The heat-conducting part is used to conduct heat in contact with the circuit board, specifically in contact with high-performance components on the circuit board. The heat is guided to the external heat sink, and the heat sink improves the heat dissipation efficiency. The top cover 1 has an extension 4 that extends laterally out of the bottom shell. The lower end of the extension has a wire passage 41. The extension 4 communicates with the mounting cavity, and the wire harness of the circuit board in the mounting cavity can extend out through the wire passage of the extension.

[0016] The top of the bottom shell 2 has an opening, and an annular recessed step 5 is provided around the opening. At least a portion of the top cover 1 is connected to the annular recessed step 5, thereby improving the tightness of the connection between the top cover and the bottom shell and providing a waterproof function. The top cover 1 is fixedly connected to the bottom shell 2 by a first screw, and screw holes are reserved on both the top cover and the bottom shell for the first screw connection.

[0017] The top of the bottom shell 2 is provided with an annular outer edge 6 around the outer peripheral wall, and mounting holes 7 are opened on the annular outer edge 6 to fix the bottom shell.

[0018] The heat sink 3 is fixed to the bottom shell 2 by the second screw. The heat sink 3 covers the bottom of the bottom shell 2 to ensure that the heat sink has a sufficiently large heat dissipation area, thereby ensuring its heat dissipation effect.

[0019] This application also provides a range hood having the control box structure described above.

[0020] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments.
