[0036] Please refer to Figures 1-7This utility model provides an electrical box assembly for a range hood, including an electrical box 1, a volute 62, and a cooling fan 61. The electrical box 1 includes a box body 11, with a receiving cavity 10 inside. An air inlet 12 is located on a first side of the box body 11, and an air outlet 13 is located on a second side. The volute 62 is installed in the receiving cavity 10 and forms an air chamber 100 with the inner wall of the box body 11. An air inlet 620 is located on the volute 62, connecting the receiving cavity 10 and the air chamber 100. The air chamber 100 communicates with the air outlet 13. The cooling fan 61 is installed in the air chamber 100 and connected to the box body 11. A main control board 3 is installed inside the receiving cavity 10. When the electrical box assembly is working, the main control board 3 runs and the cooling fan 61 runs, drawing in the cold air outside the electrical box 1 through the air inlet 12 into the accommodating cavity 10, and drawing the hot air generated by the main control board 3 through the air inlet 620 into the air cavity 100, and then sending it out through the air outlet 13, thereby achieving the heat dissipation effect on the electrical box 1.

[0037] The electrical box assembly of the range hood provided by this utility model is directly connected to the box body 11 via a cooling fan 61. The volute 62 and the box body enclose and form a wind cavity 100. Compared with the prior art where the wind cavity 100 is formed in a separate volute 62 and the cooling fan 61 is installed in the volute 62, the installation between the cooling fan 61 and the box body 11 in this embodiment is more compact. There is no installation gap between the cooling fan 61 and the box body 11, thereby reducing the vibration generated by the cooling fan 61 during operation, resulting in less noise. The electrical box assembly is also more compact and has a better heat dissipation effect.

[0038] Optionally, the box body 11 is integrally formed with a mounting part 15, and the middle part of the heat dissipation fan 61 is mounted on the box body 11 through the mounting part 15. The structure is simple and compact and easy to install.

[0039] Optionally, a volute shell surround 14 corresponding to the volute shell 62 is integrally formed on the inner wall of the box body 11. The volute shell 62 is connected to the volute shell surround 14 to form an air cavity 100 between the volute shell surround 14 and the inner wall of the box body 11, so that the volute shell 62 can be installed on the inner wall of the box body 11 by connecting with the volute shell surround 14.

[0040] Optionally, the volute 62 and the volute perimeter 14 are connected by screws.

[0041] Optionally, the system also includes a first oil filter 71 disposed at the air inlet 12 and / or a second oil filter 72 disposed at the air outlet 13. The first oil filter 71 filters oil fumes from the cold air outside the electrical box 1 and also blocks the air inlet 12 to reduce the entry of foreign objects into the accommodating cavity 10 through the air inlet 12. The second oil filter 72 further filters the air discharged from the electrical box 1 and also blocks the air outlet 13 to reduce the entry of foreign objects into the accommodating cavity 10 through the air outlet 13.

[0042] Optionally, it also includes a rectifier bridge 4 mounted on the main control board 3, a volute 62 mounted on the inner wall of the upper side plate of the housing body 11, a main control board 3 mounted on the lower side of the accommodating cavity 10, and a rectifier bridge 4 located below the air cavity 100. This facilitates heat dissipation for the main control board 3 and the rectifier bridge 4.

[0043] Optionally, a heat sink 5 is also included. The heat sink 5 is mounted on the main control board 3 and located on one side of the rectifier bridge 4. The heat sink 5 is positioned below the air inlet 620. The heat sink 5 is used to dissipate heat from the main control board 3 and the rectifier bridge 4. The heat absorbed by the heat sink 5 then flows through the air inlet 620 into the air cavity 100, and then flows out of the electrical box 1 through the air outlet 13.

[0044] Another aspect of this utility model provides a range hood, including the electrical box assembly of the range hood described above.

[0045] Optionally, the system includes a chassis and a range hood fan, with the range hood fan installed inside the chassis and the electrical box assembly installed on the top plate structure 2 of the chassis.
