Description
Technical field
The present invention relates to it is a kind of be equipped on air conditioner by the molding turbofan of thermoplastic resin, being related to one kind can be true
Recognize and improve the turbofan of welding quality.
Background technology
The turbofan of the prior art includes being integrally formed mainboard by thermoplastic resin and overleaf having the bag of opening
The fan main body and shield of multiple blades of the hollow structure of shape.In addition, on each blade of fan main body, in the front end of blade
Portion forms the chimeric recessed portion with the connection of blade hollow portion, and is formed from shield to fan in the position of each blade of the correspondence of shield
The extended engagement protrusion of short transverse.
In addition, the engagement protrusion of shield be inserted into fan main body chimeric recessed portion after, the surface of shield and formation
The chimeric recess of the side and fan main body of the vane nose weld part of the inclined surface of fan main body and the engagement protrusion of shield
The side in portion is fixed and is integrally formed, to form turbofan.In the shield and fan main body of the fixation formation, can pass through
The engagement protrusion of shield and the chimeric recessed portion of fan main body are easily and securely positioned (for example, can refer to patent text
It offers 1).
The turbofan of the prior art is constituted with the structure, to which in fixed shield and fan main body, it is fixed to can be improved
Position precision.But before shield and the welding surface of fan main body is the surfaces of shield and the blade as the inclined surface of fan main body
The side for holding the side of the engagement protrusion of weld part and shield and the chimeric recessed portion of fan main body, in assembly welding shield and
When fan main body, the two is pressurized along the rotary axis direction (upper and lower directions) of turbofan, but because of the vane nose of fan main body
Weld part is obliquely installed along the direction of rotation of blade, and vane nose weld part becomes inclined surface, therefore the power loss of upper and lower directions,
Blade is reduced welding force by the power of horizontal direction, it is possible to be unable to uniform welding.
