The utility model changes the structure of the traditional cooking fume exhauster, the utility model is composed of a cooking fume hood, a fume exhaust tube and a rotating blade device, the rotating blade device is arranged on the tail of the fume exhaust tube, the upper end of the cooking fume hood is communicated with the fume exhaust tube, a through port is arranged between the exhaust port of fume exhaust tube and the rotating blade, the rotating blade and the cooking fume are separated thoroughly, and the utility model is free from being cleaned.

Description

Exempt to clean smoke exhaust ventilator

The utility model relates to a kind of smoke exhaust ventilator, especially a kind of smoke exhaust ventilator of exempting to clean.

The household smoke exhaust ventilator ubiquity is cleaned the shortcoming of difficulty at present, this mainly is that unreasonable structure by existing smoke exhaust ventilator causes, this smoke exhaust ventilator all is that the motor drives rotating vane rotates directly suction oil smoke, oil smoke contacts with rotating vane and makes grease have to stick on the rotating vane, in the course of time, grease on the rotating vane adheres to too thick and influences its function, has to often clean.

The purpose of this utility model is to provide a kind of smoke exhaust ventilator of exempting to clean, and oil smoke is not contacted with rotating vane, removes the hardship of scouring from.

The purpose of this utility model is achieved in that a kind of smoke exhaust ventilator of exempting to clean, form by oil smoke cover, smoke exhaust pipe and Impeller fan, the exhaust opening of smoke exhaust pipe communicates with atmosphere, the afterbody of smoke exhaust pipe is equipped with Impeller fan, Impeller fan is towards exhaust opening, the upper end of oil smoke cover communicates with smoke exhaust pipe, and port is between the exhaust opening and Impeller fan of smoke exhaust pipe.

The sectional area of said smoke exhaust pipe diminishes gradually from afterbody to exhaust opening.

Said oil smoke cover is horn-like.

The rotating vane of said Impeller fan has 1～5 grade.

Adopt such technical scheme, changed the structure of traditional smoke exhaust ventilator, rotating vane rotates and form airflow in smoke exhaust pipe, thereby passage port pressure is reduced, make oil smoke be inhaled into smoke exhaust pipe from oil smoke cover, be blown smoke exhaust pipe again, oil smoke does not reach rotating vane all the time like this, rotating vane thoroughly separates with oil smoke, removes the hardship of scouring from.

Further describe the utility model below in conjunction with accompanying drawing.

Fig. 1 is a side sectional view of exempting to clean smoke exhaust ventilator.

As shown in Figure 1, exempting to clean smoke exhaust ventilator is made up of oil smoke cover (1), smoke exhaust pipe (2) and Impeller fan (3), the rotating vane of Impeller fan (8) is driven by motor (7), be installed in the afterbody (4) of smoke exhaust pipe, exhaust opening (6) towards smoke exhaust pipe, said exhaust opening (6) communicates with atmosphere, the upper end of oil smoke cover (1) communicates with smoke exhaust pipe (2), port (5) is positioned between the exhaust opening (6) and rotating vane (8) of smoke exhaust pipe, the sectional area of smoke exhaust pipe (2) diminishes gradually from afterbody (4) to exhaust opening (6), oil smoke cover (1) is horn-like, and the rotating vane of Impeller fan (8) has 2 grades.
