[0032] Reference Figures 2 to 3 According to the first embodiment of the present invention, the oil guide structure of the wind cabinet includes a box body 100, a fan volute 200, an oil guide plate 300 and an oil receiving pan 400. The box body 100 has an accommodating chamber 110, and the fan volute 200 is arranged in the accommodating chamber 110. The fan volute 200 includes a volute plate 210, a front side plate 120 and a rear side plate. The front side plate 120 is arranged at the front end of the volute plate 210, and the rear side plate is arranged at the rear end of the volute plate 210. The oil guide plate 300 is arranged at the upper part of the accommodating chamber 110. The oil guide plate 300 can guide oil to the outer surface of the fan volute 200. The oil receiving pan 400 is arranged on the box body 100 or the fan volute 200, and the oil receiving pan 400 is located below the volute plate 210. By arranging an oil guide plate 300 at the upper part of the accommodating chamber 110, the oil on the upper part can be guided to the fan volute 200. The surface of the volute plate 210 of the fan volute 200 is a curved surface. Most of the oil can be guided by the volute plate 210 and gathered to the bottom of the volute plate 210, so that the oil can be concentrated at the bottom of the volute plate 210 and drip onto the oil receiving pan 400, so that the size of the oil receiving pan 400 can be set relatively small, which will not affect the exhaust effect, and the setting position of the oil receiving pan 400 has relatively little effect on the exhaust effect.

[0033] Specifically, when the range hood is in use, oil and dirt will gradually accumulate in the box body 100 of the wind cabinet. The oil and dirt on the inner side wall of the box body 100 can flow down along the side wall to the oil cup or oil receiving groove of the range hood. By arranging an oil guide plate 300 on the upper part of the box body 100, the oil and dirt above can be directed toward the fan volute 200, so that it will not drip directly downward and contaminate the stove or food below. The contour of the volute plate 210 of the fan volute 200 is an arc-shaped, and the oil and dirt can flow down along it to the bottom of the volute plate 210 and can be further directed to the oil receiving pan 400. Due to the special shape of the fan volute 200, the area where oil and dirt gather at the bottom is relatively small, and the oil collecting pan 400 can be set relatively small, which can save costs. In addition, the small size of the oil collecting pan 400 can reduce wind resistance, which has a relatively small impact on the suction effect. It can be understood that the oil collecting pan 400 can be provided with a pipe at the bottom to guide the oil and dirt to the oil collecting tank of the range hood, which eliminates the need for frequent maintenance of the oil collecting pan 400, and the air suction port of the fan volute 200 can be set forward. The oil collecting pan 400 is set at the bottom of the fan volute 200, which has a relatively small impact on the suction effect.
