Abstract

A vortex air flow type range hood comprises a main shell body, an oil fume extraction cover, a net cover, a motor, a belt pulley, an exhaust roller, a bearing base with a bearing, a driving belt, an oil removal plate, a cone fan cover, and a blade. With a fan system formed by the vertical exhaust roller and the cone fan cover, the discharge flue of the range hood is not obstructed by any object, and the flue is clear; the area of the air rotated by the cone fan cover exceeds that of a conventional range hood, and the cone fan cover has the blade with a certain angle so that revolving air locally forms swirling air flow that is intense and rises rapidly; therefore, the suction of the range hood is stronger, achieving a better effect.

Description

Vortex airflow range hood

The invention relates to a range hood device

Background technique

The structure of the range hood on the market is mostly that the roller fan is lying on the flue, and the motor is driven to generate the upward airflow. The position of the blower has already affected a certain flow of the flue gas. The long-term use of the fan blade will seriously accumulate oil, the impeller. It will gradually lose its balance, resulting in low efficiency, high energy consumption, high noise, short life, and troublesome cleaning and disassembly.

SUMMARY OF THE INVENTION A fan system consisting of a conical fan cover, an unobstructed flue and capable of generating a strongly rising vortex flow, a consuming wattage, a greater suction force, and a more convenient hood.

The object of the present invention is achieved by the following measures

A vortex airflow range hood comprising a main casing, a suction hood, a mesh cover, a motor, a pulley, an exhaust roller, a bearing housing with bearings, a transmission belt, a grease trap, a tapered fan cover, and a blade The vortex airflow range hood is characterized by:

The main casing is provided with an upper end panel with a discharge round port and a lower oil barrier plate with a discharge round opening; the motor is erected and fixed on the upper end plate of the main casing, and the drive shaft of the motor is provided with a pulley; The upper part of the drum is provided with a pulley, and the bearing seat with bearing is arranged at both ends, and is vertically and symmetrically mounted and fixed on the upper end panel of the main casing and the exhaust round port of the lower oil barrier; the transmission belt is sleeved on the pulley and the row of the motor The lower end of the exhaust roller extends beyond the bearing seat and is fixedly connected with the tapered fan cover; the lower end of the tapered fan cover is provided with a corresponding blade and arranged at an angle; the oil hood is fixed and fixed at the main The oil barrier plate under the casing; the mesh cover is mounted on the lower end surface of the oil hood. After adopting such a structure, there is no object blocking on the exhaust flue of the range hood, the flue becomes very smooth, and the rotating circular area of the conical fan cover under the exhaust drum also exceeds the flue aperture of the conventional range hood, the cone The air swirled from the blade with a certain angle on the fan cover forms a strong and rapidly rising vortex flow to make the suction of the range hood larger and better.

detailed description

The implementation of the utility model will be further described in detail below with reference to the accompanying drawings.

As shown in Fig. 1, on the upper end surface of the main casing 1, there is an upper end panel 2 having a discharge round opening and a lower oil barrier 3 having a discharge round opening on the lower end surface. The main shaft of the motor 4 is passed through a matching hole of the upper end plate of the main casing 1, and the motor 4 is erected and fixed on the upper end plate of the main casing 1, and the pulley 5 is mounted on the main shaft of the motor 4. The upper part of the exhaust drum 6 is provided with a pulley 7 which passes through the bearing housing 8 with the bearing, the lower end passes through the bearing housing 9 with the bearing and the lower port extends beyond the bearing housing 9, the bearing housing 8 and the bearing The seats 9 are vertically and symmetrically mounted and fixed to the exhaust port of the upper end panel 2 and the lower oil barrier 3 of the main casing 1. The drive belt 10 is placed on the pulley 5 of the motor 4 and the pulley 7 of the exhaust drum 6. A circular tube on the conical fan cover 11 is sleeved in the inner diameter of the exhaust cylinder 6 and bolted. The lower end of the conical fan cover 11 is provided with a corresponding vane 12, and the vanes 12 are arranged at an angle. The oil hood 13 is mounted and fixed to the lower oil barrier 3 of the main casing 1. The net cover 14 is mounted on the lower end surface of the oil hood 13 . Thus, a vortex flow type range hood is formed. When the motor 4 rotates, the pulley 5 on the main shaft of the motor 4 drives the belt 10 to drive the exhaust drum 6 and the cone fan cover 1 1 through the pulley 7, and the blade 12 rotates the air above and below the cone fan cover 11. A strongly rising vortex flow is formed, which doubles the air suction of the range hood.
