Description
Technical field
The present invention relates to heat the warm-air drier that room air is used, particularly relate to a kind of hot blast diffusion structure of warm-air drier of the hot blast area coverage that enlarges warm-air drier.
Background technology
Be equipped with electric heater unit on small-sized household electric heating products such as warm-air drier, traditional electric heating device comprises resistance wire, electric heating sheets etc., the no temp regulating function of this class electrothermal device self, thereby service life is short, fault rate height, poor stability.The electrothermal device that another kind is called PTC (positive temperature coefficient) then replaces traditional heater members because of it has advantages such as reliability height, easy to use, safe, power saving, is widely used in various fields such as electric power facility, electronic equipment and automobile industry.This PTC electrothermal device is a kind of semiconductor function ceramics with positive temperature coefficient.PTC at transition temperature (Tc) before, resistance descends with the rising of temperature; Temperature from transition temperature to the design maximum temperature before, resistance is phenomenal growth with the rising of temperature, forms the PTC effect.Utilize the PTC effect,, can make the PTC thermal sensitive ceramics of different purposes according to different temperatures coefficient.
Electrothermal device on the existing warm-air drier all uses with the fin combination, its structure as shown in Figure 1, in the both sides of electrothermal device 1 metal heat sink 2 is housed, the heat that electrothermal device produces through radiator to external radiation, the air of being sent into by the wind wheel 3 that is arranged at the electrothermal device rear portion is heated, and hot blast forwards blows out through radiator.As shown in Figure 1, the air-out area of traditional warm-air drier is the area (width A in Fig. 1) wide with its heat generating component, and its hot blast coverage rate is very little.For this reason, people have to adopt increases oscillating mechanism on warm-air drier, enlarge heating surface (area) (HS by mobile hot blast air outlet.Also the someone adopts method as shown in Figure 2, uses a plurality of independently heat generating components 1, and is provided with independent guide vane 4 between heat generating component and wind wheel, and this guide vane is arranged at the rear portion of heat generating component, changes the wind direction of wind wheel by guide vane.This method structure relative complex causes small product size to increase, and processing difficulties and cost are higher.
Summary of the invention
The present invention 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 invention 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 example tilts outside radiator, 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 invention 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.
