Summary of the invention

The utility model is intended to address the above problem, and a kind of air outlet outside of the hot blast of warm-air drier can being led is provided, thereby has effectively increased the hot blast area coverage, and simple in structure, is easy to assembling, the hot blast diffusion structure of the warm-air drier that production cost is low.

For achieving the above object, the utility model provides a kind of hot blast diffusion structure of warm-air drier, this structure comprises heater and is located at the radiator of heater outside, it is characterized in that being provided with at least one between radiator and warm-air drier air outlet will be through the guide vane in the hot blast guiding outside that fin blows out.

Guide vane and radiator are installed in the warm-air drier air outlet place of radiator front portion separately, and to the inclination of the radiator outside, specifically, guide vane is located on the warm-air drier wind outlet frame of being made by heat proof material, and wind outlet frame is the tubaeform framework that the air outlet shape with warm-air drier matches.

The outer surface of the guide vane and the radiator of the side that tilts with it or with the outer surface of radiator between parallel interplanar angle α be acute angle.

Guide vane is the plate body of plate shaped, V-arrangement, U-shaped or arc.

Radiator is the corrugated radiator that front and back connect.

Heater is contained on the heater seat, and heater can be any in heating wire, heating sheet, heat-generating pipe or the PTC heat generating member.

Many group radiators are linked to be an integral body by a plurality of side plates, between two unit radiators of every group of radiator a heater are housed.

Contribution of the present utility model is that the hot blast coverage rate that it efficiently solves warm-air drier is little, and causes complex structure, defectives such as small product size and cost raising owing to increase coverage rate.By between heater and air outlet, guide vane being set, can so not only improve the hot blast coverage rate greatly, and simplify the structure greatly by the heater heated air stream guiding air outlet outside, thereby be easier to processing and assembling, and effectively reduce production cost.
