Description
Technical field
The present invention relates to a kind of dryer, belong to dryer apparatus field.
Background technology
Dryer work general principle is to heat the air of relatively dry, dry air is reached that dry air can after heating up
Carry the ability of moisture content.The xeothermic air of high temperature is sent into drum for clothes drier by fan, is touched after wet wash to wet clothing
Thing is heated, and the moisture content in wet wash is separated out in the form of water vapour, and now the xeothermic air of high temperature absorbs rapidly clothing
The vapor on surface is changed into the saturated moist air of high temperature, then high temperature saturated moist air taken away clothing by the effect of fan
Thing, so as to reach the purpose of drying.At the same time, can uniformly it be dried for the clothing that ensures in drum for clothes drier, drying
Machine cylinder is rotated with to clothing around centre of the drum's axis one-directional rotation unidirectional, counterclockwise clockwise or along alternately regular counterclockwise
Thing is stirred, and can so be made cloth drying uniform and can be shortened the clothes drying time, and reduction clothing winding, lifting is used
Family use feeling.Air-intake device includes the fan in spiral case and spiral case, and heater is provided with air-intake device air outlet, but
In operating practice, the main flow of air-flow always flows along the side wall of direction of rotation to heater and occurred in offside more tight
The backflow phenomenon (see Fig. 1) of weight, this reduces the utilization ratio of heater, and also results in heater
There is certain potential safety hazard in hot-spot, in order to avoid the appearance of this hidden danger, temperature is implemented to heater in practice
Protection control, the control can cut off heater strip power supply when heater temperature exceedes the safe temperature set, be allowed to stop
Heating, but drying efficiency can be so reduced, extend drying time and multiple power on/off can influence the electric elements life-span.
In view of this it is special to propose the present invention.
The content of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art there is provided a kind of dryer, to fan air-out
Position is improved, and have adjusted the backflow of air-flow main flow, improve the utilization ratio of heater, it is to avoid heating dress
The potential safety hazard that hot-spot is caused is put, drying efficiency is improved.
In order to solve the above technical problems, the present invention is using the basic conception of technical scheme：

Being equipped with guiding device and guiding device and fan periphery has a gap, and guiding device be symmetrical structure and its be centrally disposed in
On the axis of symmetry of spiral case inner chamber.
Further, seen along the radial direction of fan, one end of guiding device towards fan is long, one end towards fan is short, shape
Into class triangle or triangular structure.
Further, length of the guiding device along the radial direction of fan is less than fan diameter.
Further, guiding device is inverted T-shaped, including bottom plate and is connected with bottom plate and the vertical part in the middle part of bottom plate, bottom
The bottom surface of plate is towards fan, and the free end of vertical part is away from bottom plate and towards spiral case air outlet, and vertical part is perpendicular to bottom plate bottom surface.
Further, the bottom surface of inverted T-shaped guiding device is cambered surface, and cambered surface extends along fan periphery.
Further, the vertical part of inverted T-shaped guiding device passes through inclined-plane or cambered surface from its free end to it with back plate connections
Transition, vertical part is gradually broadened from its free end to it with back plate connections by narrow；The free end of vertical part is arc.
Further, the top surface of the bottom plate of inverted T-shaped guiding device is cambered surface；The top surface of the bottom plate of inverted T-shaped guiding device with
Pass through cambered surface transition between bottom surface.
Further, the left side between the arc center of circle and the top surface of bottom plate and bottom surface of the free end of inverted T-shaped guiding device vertical part
The angle 30-90 degree of the angle α of the circle center line connecting formation of right two arcs.
Further, guiding device is triangle, and the bottom surface of triangle is towards fan, and vertex angle is towards spiral case air-out
Mouthful, pass through cambered surface transition between two waists of triangle guiding device and bottom surface.
Further, the drift angle of triangle guiding device is cambered surface；Two waists of triangle guiding device be plane or cambered surface,
And cambered surface is the cambered surface of outward bulge.
After adopting the above technical scheme, the present invention has the advantages that compared with prior art.
Dryer of the present invention, blower fan is provided with it, and blower fan includes spiral case and fan, and spiral case inner chamber is symmetrical structure, wind
Fan is arranged on the axis of symmetry of spiral case inner chamber positioned at spiral case inner chamber and fan center, in fan towards the one of spiral case air outlet
Side is provided with guiding device and guiding device has gap with fan periphery, and guiding device is symmetrical structure and its center is set
On the axis of symmetry for being placed in spiral case inner chamber, by guiding device, make the air-flow main flow that fan is produced along guiding device side and
Its relative spiral case side wall flows to heater, and the most areas or complete of air-flow main flow covering heater
Portion, has less air-flow to be turned back after the opposite side wall of spiral case is encountered and is flowed to fan directional, due to there is guiding device, therefore
This fraction can be rejoined in the rotation of fan under the guiding of the opposite side wall and guiding device of spiral case, without
The backflow gathered is produced between fan and volute outlet.Dryer of the present invention improves the flow and pressure of fan, so as to realize
The improved efficiency of blower fan, guiding device can improve the problem of heater temperature distributing disproportionation is even, improve heating
