Problems solved by technology

[0006] None of the above-mentioned fans can increase the air pressure and air volume at the same time, so when high air pressure and high air volume are required, its size needs to be increased. Therefore, due to the increase in the volume of the fan, the volume of the entire home appliance will also increase.
[0007] Because the air flow direction of the inlet and outlet of the centrifugal blower fan is different, it is easy to be restricted by the position when setting it.
At the same time, the air volume of the previous blower fan is significantly reduced or almost no when it is reversed, so the blown air can only be rotated in one direction, which cannot increase the function of the system

Embodiment Construction

[0020] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail: figure 1 and figure 2 It is an embodiment of the blower fan assembly of the present invention. The spiral blower fan assembly in the embodiment includes: a rotating shaft 11 that rotates together with a driving motor (not shown in the figure); a longer cylinder fixed on the rotating shaft 11 type wheel hub 12; on the outer peripheral surface of the wheel hub 12 along the axial direction from one end to the other end twisted into a helical blade 13; in order to suck and discharge air, adopt a hollow cylindrical structure with both ends open, and surround the The fan cover 14 on the outside of the blade 13 rotation track constitutes.

[0021] Along the circumferential direction, several through holes that can discharge or inhale air are arranged at certain intervals on the side portions adjacent to the two ends of the fan cover 14 .

[0022] Two ...

Abstract

The invention provides a helical blowing fan groupware and includes axis of rotation circumvolving with the actuating motor, long columnar hub fixed on the axis of rotation, helical blade along the circumferential surface of the hub from one end to the other end and fan casing, which is open at two end and hollow to inbreathe and discharge the air, covers the outside of the track of the above-mentioned blade and has several holes in certain distance at the end of the suction end. The invention can increase the inspiratory capacity and get the high air delivery and high wind pressure without increasing the size of the helical blade. The air flows along the direction of axis, so it is not limited by the location of the fan and can reduce the size of the whole system.

Description

technical field [0001] The present invention relates to a fan, in particular to a helical blower fan assembly. In particular, it relates to a helical blower fan unit that can send out air in the axial direction with high air volume and high air pressure installed in home appliances such as air conditioners or other manufacturing equipment. Background technique [0002] Generally, various types of blower fans that force flow air are installed in home appliances including air conditioners or factory ventilation systems, and such blower fans are roughly divided into axial flow blower fans and centrifugal blower fans according to the flow characteristics of the blown air. type fan. [0003] The air flow direction in the axial flow fan is parallel to the rotating shaft. Although the air flow is large, the compressed air pressure is relatively low. [0004] In a centrifugal blower fan, air flows in parallel to the shaft at the inlet of the blades and perpendicular to the shaft w...
