Detailed description of the invention
As Figure 1-5, the utility model comprises defrosting duct body 12, defrosting duct body 12 is provided with air channel import 1, ducting outlet 2 and side defrosting pipe 3, described air channel import 1 is positioned at defrosting duct body 12 bottoms and is connected with air-conditioning, and described ducting outlet 2 is positioned at defrosting duct body 12 tops and is connected with defroster grill.Described air channel import 1 communicates with ducting outlet 2 and side defrosting pipe 3, forms one and enters the three four-way structures that go out.The transverse width of ducting outlet 2 of the present utility model is greater than the transverse width of air channel import 1, air channel import 1 is to ducting outlet 2 the expansion trend of dispersing, the fish tail shape that formation waist is arc, and according to the bore length of air channel import 1, ducting outlet 2, and the region that need to defrost of windscreen, from bottom to top determine the outline line that extends out of air channel sidewall 11.
Defrosting duct body 12 is made up of air channel protecgulum 13 and air channel bonnet 14, in the middle of the inner chamber of air channel, the transverse center position of air channel protecgulum 13 is provided with a V-arrangement and divides wind guide plate 5, and affiliated V-arrangement divides the bottom of wind guide plate 5 higher than the side defrosting pipe inner spout 17 of side defrosting pipe 3.Described V-arrangement divides the top of wind guide plate 5 along being provided with two blocks of vertical flaps 16 perpendicular to the direction of inwall, aligns with ducting outlet 2 in the top of flap 16.The tube wall of described two the side defrosting pipes 3 in left and right is provided with side defrosting wind-guiding muscle 4 in from the mouth of pipe to pipe, and the warm braw of air-conditioning enters defrosting duct from air channel import 1, is first divided into three strands of air-flows by two sides defrosting wind-guiding muscle 4: both sides and centre.Two strands of air-flow approaching side defrosting pipes 3 of both sides are for side defrosting, and defrosting wind-guiding muscle 4 makes both sides can distribute enough warm braws.One middle air-flow continues up, is divided into two parts again air-flow and spreads to both sides running into after V-arrangement divides wind guide plate 5.In the cavity of divergence form air channel on mobile in, diffusion, blows to windscreen from ducting outlet 2 outside the sidewall 11 in air channel, continues to diffuse to form a fan-shaped flow area, covers the region that whole windscreen need to defrost.Two blocks of flaps 16 that described V-arrangement divides the end of wind guide plate 5 to be provided with vertical setting, make V-arrangement divide wind guide plate 5 to obtain the trend of top formation toe-in.Air-flow, along convergence profile, is gathered to centre, forms the gesture of converging while arriving glass surface, has eliminated the air-flow blind area being formed because divide wind guide plate 5 to stop by V-arrangement.
The inwall that defrosting duct is made up of air channel protecgulum 13 and air channel bonnet 14 comprises that upwards linearly extended air intake guide section 15 and straight line extend to the air-out guide section 9 of ducting outlet 2 along air channel import 1, be smoothly connected by the air inducing transition phase 10 of arc between the two, between air intake guide section 15 and air-out guide section 9, shape forms an angle.The direction of described air-out guide section 9 is not orthogonal to defroster grill, but along the inclination angle of windscreen trend, air-out direction and glass inwall form acute angle.Air-out guide section 9 is smoothly connected by air inducing transition phase 10 with air intake guide section 15, forms broken line trend, therefore defrosting duct body 12 side myopia are in fold-line-shaped.The warm braw that air-conditioning is sent into, under the directional tagging of defrosting duct air-out guide section 9, upwards brushes and climbs along glass inwall, and air-flow, under the double action of this inclination angle guiding and fan-shaped guiding, finally covers whole front windshield glass, effectively carries out defrosting-defogging.
Air channel of the present utility model protecgulum 13 and air channel bonnet 14 position by the registration mast 7 being positioned on air channel bonnet 14, and attach together and form defrosting duct assembly by self buckle, by being positioned at the screw hole 6 on the protecgulum of air channel and being positioned at the locating dowel pin 8 on air channel bonnet 14, defrosting duct body 12 and instrument carrier panel body are carried out to screw to be fixed, need not welding process, good economy performance.
The above; be only detailed description of the invention of the present utility model, it should be pointed out that any those of ordinary skill in the art are in the disclosed technical scope of the utility model; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.
