Summary of the invention
The purpose of this utility model is in order to solve the technological deficiency that existing cross flow fan exists, to disclose the cross flow fan that a kind of ducting assembly is not yielding, motor can not produce magnetic loss because of leakage field.
In order to realize above-mentioned purpose, the utility model has adopted following technological scheme:
A kind of cross flow fan comprises ducting assembly, impeller, motor and rotating shaft, and ducting assembly is made of coaming plate, hyoplastron and 2 blocks of side plates, and 2 blocks of side plates are installed in the two ends, the left and right sides of coaming plate respectively; Hyoplastron is installed between two blocks of side plates, and hyoplastron and coaming plate be arranged in parallel; Rotating shaft runs through two blocks of side plates of ducting assembly, impeller is installed in the rotating shaft in the ducting assembly, and motor is installed on wherein the side plate, and motor connects an end of rotating shaft, side plate all is connected by screw with hyoplastron with coaming plate, side plate, and a side plate of installation motor is a plastic board.
As preferably, on the position of coaming plate and two ends, the hyoplastron left and right sides and side plate joint respectively punching out the screw mounting groove is arranged, screw passes side plate and inserts in the screw mounting groove, coaming plate is connected very firm with side plate, side plate with hyoplastron.
As preferably, the screw mounting groove is half slot or U type groove.
As preferably, on two ends, the left and right sides madial wall of described coaming plate respectively punching out a plurality of screw mounting grooves are arranged, and the screw mounting groove on the two ends, the left and right sides is rational in infrastructure along coaming plate mid point symmetric arrays, air duct performance is good.
As preferably, coaming plate and hyoplastron are aluminium diecastings, and side plate is a plastic board, and the relative galvanized sheet material of aluminium diecasting is softer, and punching out screw mounting groove is very easy to.
Because adopted a kind of cross flow fan of above-mentioned technological scheme, coaming plate all adopts screw to be connected with side plate, side plate with hyoplastron, have easy for installationly, the on-deformable advantage of coaming plate, side plate and hyoplastron has improved the utilization efficiency of blower fan; The side plate that motor is installed is a plastic board, not only can solve the problem that does not have protective housing generation leakage field magnetic loss because of cover level motor, and plastic side panel can also reduce the probability that resonates between the fan part.In sum, this cross flow fan has easy for installation, and ducting assembly is not yielding, the advantage that the blower fan utilization efficiency is high, and the while can not produce the problem of magnetic loss because of leakage field.
