Detailed Description

In the following, an embodiment of the present invention will be described in detail with reference to the drawings, but it should be understood that the scope of the present invention is not limited by the embodiment.

Example (b):

as shown in fig. 1-6, a wall-hanging fresh air ventilator, including casing 1, casing 1 can be the cuboid, and the cuboid casing is convenient for make and install, casing 1 has supply-air outlet 11 and air exit 12, casing 1 internal fixation is equipped with air supply fan 2, supply-air outlet 11 with air supply fan 2's air outlet corresponds the setting, air supply fan 2's air intake and air-supply line 3 intercommunication, air exit 12 and exhaust pipe 4 intercommunication.

Specifically, the air supply fan 2 is a centrifugal fan, and a plurality of air supply outlets 11 are correspondingly arranged on the peripheral wall of the casing 1. Be equipped with a plurality of air exit 12 that runs through its thickness on casing 1, set up the four corners department of casing 1, it through exhaust converge the pipe 5 with exhaust duct 4 intercommunication, exhaust duct 4 is located in air-supply line 3, air-supply line 3 is in through a plurality of support 7 suit is in on the exhaust duct 4.

Specifically, the exhaust converging pipe 5 comprises a plurality of branch pipes 51 and a converging main pipe 52, one ends of the branch pipes 51 are communicated with the exhaust outlets 12 in a one-to-one correspondence manner, the other ends of the branch pipes are communicated with the converging main pipe 52, and the converging main pipe 52 is connected with the exhaust pipe 4.

In order to prevent rain, the tail end of the exhaust pipe 4 is bent downwards, and the tail end of the air inlet pipe 3 is provided with a rain cover 8.

In order to ensure that the air entering the room is cleaner, an annular filter screen 6 is arranged between the centrifugal fan and the air supply outlet 11.

The utility model discloses a theory of operation: as shown in fig. 5, a mounting hole is drilled on the wall, the new air blower is mounted and fixed, the casing is located indoors, the air pipe extends out of the wall through the wall hole, the air supply blower 2 is started, outdoor new air enters from the air inlet pipe 3 (i.e. a gap between the air inlet pipe 3 and the air exhaust pipe 4) under the action of the air supply blower 2, the new air is dispersed to each air supply outlet 11 under the action of the centrifugal blower, air supply to the indoor is completed, positive pressure is generated on the indoor side relative to the outdoor side along with the air supply, indoor air enters the air exhaust converging pipe 5 through the air exhaust outlet 12, and finally the air is exhausted to the outdoor through the air exhaust pipe 4, so as to complete fresh air ventilation.
