Detailed Description
The small household ventilator has the following schematic diagram:
example one
As shown in fig. 1, fig. 2, fig. 3 and fig. 4, the rear air duct 5 of the ventilator has an air inlet and outlet duct 6, the air inlet and outlet duct 6 has a vent 61 and a vent 62, the right side inclined plane of the face cover 2 has an air outlet 22, the left side inclined plane has an air inlet 21, and the ventilator has a fan 4 and a fan 12.
During ventilation, the fan 12 is started, fresh air is sucked from one vent 62 of the air inlet and outlet pipes 6, enters the fan 12 through the air duct 52 in the air guide pipe 5 and then is injected into a room from the air inlet 21 on the left inclined surface, the fan 4 sucks indoor dirty air from the air outlet 22 on the right inclined surface into the air duct 51 in the air guide pipe 5, and then the dirty air is discharged out of the room through the other vent 61 of the outdoor air inlet and outlet pipe 6, so that the dirty air in the room is sucked out from the air outlet 22 on the right inclined surface of the surface cover 2, the fresh air is sucked from the air outlet 21 on the left inclined surface, the air inlet direction and the air outlet direction in the room are larger than 120 degrees, and a large air convection ring is formed in the room, so that the air in the room and the outside is.
