Description

Roof electric extractor

technical field

The utility model relates to a roof exhauster, in particular to a roof electric exhauster with improved structure.

Background technique

Present electric roof extractor, its structure is as shown in the combination sectional drawing of Fig. 1, mainly comprises an air cylinder body that can be placed and fixed on the roof, is provided with top cover above the air cylinder body, is provided with in the air cylinder body Bracket, set a motor body with fan blades in the center of the bracket and stand upright. When the power is turned on, the motor body can discharge the indoor hot air to the outside. But its disadvantage is that when the motor body is running, as shown by the arrow in Figure 1, When the indoor hot air is pumped from bottom to top to the top cover, it is blocked from flowing downward, and the flow of hot air will inevitably cause interference with the upward hot air when it goes downward, resulting in disturbances, resulting in poor exhaust heat and increased power costs. .

Contents of the invention

In order to overcome the deficiencies of the prior art, the utility model provides a roof electric exhauster with low energy consumption and good use effect.

The technical scheme that the utility model solves its technical problem adopts is:

The roof electric exhauster includes a wind cylinder body and a top cover located above the wind cylinder body. A bracket is installed in the air cylinder body, a motor is installed on the bracket, and an exhaust impeller is installed on the shaft of the motor. A fan is installed in the top cover. Cone diffuser.

The beneficial effect of the utility model is that a cone-shaped air diffuser is installed in the top cover, and the direction of the air outlet is changed. When the indoor hot air is pumped from bottom to top to the top cover, the air flow spreads out along the wall of the cone diffuser, avoiding the flow of downward and downward hot air from being blocked when reaching the top cover, and the disturbance phenomenon caused by the interference of the downward and upward hot air. The extracted wind is also used to rapidly cool the roof around the air outlet, which speeds up the cooling effect and reduces the power cost. The blades of the exhaust fan are flanged blades, which increase the air volume and reduce the noise. The roof electric exhauster of the utility model also has the advantages of stable operation and leak-proof, and is suitable for steel structures, star sheds, iron factory buildings, etc., and can quickly extract a large amount of heat, steam, mildew and dust gathered under the sun's rays. , and make full use of the extracted airflow to quickly cool the nearby roofs, which can provide a good environment for workers and goods to work and store under cool and ventilated conditions.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is the airflow schematic diagram of current extractor;

Fig. 2 is a schematic diagram of the air flow of the utility model air extractor;

Fig. 3 is a three-dimensional split view of the utility model;

Fig. 4 is a sectional view of the utility model.

Detailed ways

With reference to Fig. 2, Fig. 3, Fig. 4, the roof electric blower comprises the top cover 1 that is installed on the wind cylinder body 3 and the top cover 3 installed on the wind cylinder body 3, and the bracket 9 is installed in the wind cylinder body 3, and the bracket 9 is equipped with Motor 8, the shaft of motor 8 is equipped with exhaust impeller 7, and a cone diffuser 2 is also installed in the described top cover 1.

The cone air diffuser in the top cover 1 of the utility model changes the direction of the air outlet. When the indoor hot air is pumped from bottom to top to the top cover, the air flow spreads out along the wall of the cone diffuser, avoiding the hot air that reaches the top cover to be blocked and flows downward, and the downward and upward hot air interfere and cause disturbance.

The air cylinder body 3 is installed on the roof 10 through the air collecting port 4 , the waterproof board 20 and the supporting frame 21 .

The edge of the cone air diffuser 2 and the top cover 1 are provided with matching through holes. The cone air diffuser 2 is installed on the top cover 1 through bolts 11. Of course, other methods such as welding on the top cover 1 can also be used. . The air collecting port 4 is installed and fixed on the wind cylinder body 3 by bolts, and can be adjusted according to the inclination of the roof during installation. The air cylinder body 3 and the top cover 2 are provided with matching through holes, and the top cover 1 is installed and fixed on the air cylinder body 3 through the support column 5 .

The draft impeller 7 is a flanged impeller, which can quickly extract a large amount of hot gas, steam, musty gas and dust gathered under the scorching sun to the outside of the house.

The support frame 21 is provided with an anti-drop net 22 to prevent objects on the roof from falling into the house, causing unnecessary trouble.

In addition, the edge of the top cover 1 is provided with a rainproof skirt 23 and a waterproof plate 20, which prevents rainwater from entering the house through the exhaust fan or the gap between the fan and the roof.
