Abstract
A blower in which on a suction side of a cross flow fan having a vortex stabilizing plate and a back guider is provided a flow dividing guider, which is different from the back guider, for changing the flowing direction of a portion of the air flow. The blower in accordance with the present invention is suitable to be used as a blower for a cooling apparatus, a heating apparatus, a ventilator, and the like, and has a wide variety of applications other than mentioned above.
Claims18
A blower for blowing air, comprising:
- a cross flow fan;
- a vortex stabilizing plate spaced apart from one side of the outer periphery of the fan;
- a back guider spaced apart from the outer periphery of the fan and extending from the side of said fan opposite said one side towards said stabilizing plate, said fan, said stabilizing plate and said back guider forming, on the same side of said fan, an air suction side and an air delivery side;
- and on said air suction side a flow dividing guider, which with said back guide forms a branching air delivery space on the opposite side of said air suction side, for dividing the air flow and enabling the air to flow in substantially two opposite directions from said air suction side back to said air delivery side and to said branching air delivery space, respectively.

A blower for blowing air, comprising:
- a cross flow fan;
- a vortex stabilizing plate spaced apart from one side of the outer periphery of the fan;
- a back guider, located in a position opposite to the position of said vortex stabilizing plate, with said cross flow fan located therebetween, said back guider being in the form of a curved surface which parts progressively from the outer periphery of said cross flow fan in the rotating direction of said cross flow fan;
- and a flow dividing guider, disposed on a suction side of said cross flow fan and parting progressively from the outer periphery of the cross flow fan in the rotating direction of said cross flow fan, an air suction space being formed between said flow dividing guider and said vortex stabilizing plate, a branching air delivery space being formed between said flow dividing guider and said back guider, and an air delivery space being formed between said vortex stabilizing plate and said back guider, said flow dividing guider including means for enabling air to flow in two substantially opposite directions from said air suction space back to said air delivery space and to said branching air delivery space.
