Range hood

The utility model provides a range hood which comprises an air duct, a volute horizontally arranged in the axial direction is arranged in the air duct, and the axial end face of the volute is connected with the air duct on the peripheral side of the volute through a connecting support. The axial end face of the volute is connected with the corresponding side of the air duct through the connecting support, the connecting position of the volute and the air duct is transferred to the left side and the right side of the volute, when the volute runs, the connecting support cannot affect the air inlet of the volute, airflow at the air inlet runs stably, and noise of the range hood is reduced; meanwhile, the occupied volume of the air duct is reduced, and the space utilization rate is increased. 本实用新型提供了一种油烟机，包括风道，所述风道内设置有轴向水平设置的蜗壳，所述蜗壳的轴向端面经连接支架与蜗壳外周侧的风道相连。通过在蜗壳的轴向端面通过连接支架与风道对应侧相连，将蜗壳与风道的连接位置转移至蜗壳的左右两侧，当蜗壳在运行时，连接支架不会对蜗壳的进风口造成影响，使进风口处的气流平稳运行，降低油烟机的噪音；同时，又缩小了风道的占用体积，提高空间利用率。
