Detailed Description
The utility model is described in more detail below with reference to the accompanying drawings. The utility model provides a difunctional smoke ventilator with outer row and internal circulation filter, its includes that shell 1, shell 1 bottom offer the smoking mouth, and smoke guide plate 2 cover is installed on this smoking mouth, its characterized in that: the air conditioner is characterized in that an air deflector is transversely arranged inside the upper portion of the shell 1, an air channel is formed by reserving a space between the air deflector and the shell 1, a fan 3 is arranged in the air channel, an air outlet of the fan 3 is connected with the air channel, the air channel is connected with an air outlet 4 and an inner air outlet 5, indoor air is sucked by the fan 3 through an air inlet 11 formed in the bottom of the shell 1, enters the air channel, is filtered and purified through the inner air outlet 5 and is discharged back into the room, or is discharged outdoors through the air outlet 4.
The inner air outlet 5 is arranged in front of the shell 1, and the inner air outlet 5 is communicated with the air inlet 11 through an air duct.
The top of the shell 1 is bent downwards in a tilting way to form a guide plate 12, the guide plate 12 is arranged to face the room, and the inner air outlets 5 are distributed on the guide plate 12.
The air outlet 4 is arranged at the top of the shell 1, and the air outlet end of the fan 3 is positioned below the air outlet 4.
