When being in tempered air and flowing to the blowout pattern of upside path R4 and downside path R5, support portion, upside 27 and plate-like portion 13f are arranged at and separate predetermined distance in the vertical direction and relative position.The prolongation path R6 that the mode being formed to extend warm braw path R2 between support portion, upside 27 and plate-like portion 13f extends.The sectional area extending the downstream of path R6 is less than the sectional area of upstream side.That is, plate-like portion 13f is positioned at the position in the cross section reducing the downstream extending path R6.
On the other hand, after making heating air-valve 13 tempered air be in as shown in Figure 2 flow to the blowout pattern of upside path R4, plate-like portion 13f extends towards upside path R4.Now, the rear portion of plate-like portion 13f is in the state of folding and unfolding in the position more on the lower of the downstream-end opening 29 than warm braw path R2 and warm braw path R2.And the rear portion of plate-like portion 13f is in the state near support portion, upside 27, and warm braw flows into air blending space R3 after flowing through the gap between plate-like portion 13f and partition wall 28.The front portion of plate-like portion 13f is arranged in air blending space R3.
And if heating air-valve 13 turns to the position cutting out upside path R4, then downside path R5 is in full-gear.Now, plate-like portion 13f is forwards separated from the upper end of partition wall 28, therefore can form air flue between plate-like portion 13f and the upper end of partition wall 28.
Defogger air-valve 14 is for opening wherein that another switches the parts of blowout pattern by cutting out defroster 22 with in air outlet 23, and comprises the turning cylinder 14a extended in left-right direction and the opening-closing plate portion 14b extended along the radial direction of turning cylinder 14a.Reference numeral 14c represents the sealing member formed by foamed urethane etc.Turning cylinder 14a is supported for, and the line of centers that can extend in left-right direction around the sidewall portion relative to housing 15 rotates.Turning cylinder 14a links with the connecting rod mechanism being arranged on housing 15 outside, and this connecting rod mechanism also links with the turning cylinder 13a of above-mentioned heating air-valve 13, therefore, it is possible to make heating air-valve 13 and defogger air-valve 14 link via connecting rod mechanism.In addition, heating air-valve 13 and defogger air-valve 14 can be worked by power element, also can operate metal wool by passenger and work to make heating air-valve 13 and defogger air-valve 14.
In the upper wall portions of housing 15, the turning cylinder 14a of defogger air-valve 14 is between defroster 22 and air outlet 23.Opening-closing plate portion 14b is swung in front-rear direction by the rotation of turning cylinder 14a.If opening-closing plate portion 14b forwards swings, then defroster 22 is closed and air outlet 23 is opened.On the other hand, if opening-closing plate portion 14b rearward swings, then air outlet 23 is closed and defroster 22 is opened.
The cam face that known connecting rod mechanism can be utilized to have sets the mode of motion of heating air-valve 13 and defogger air-valve 14.Be configured in this embodiment to switch to blowout pattern as described below: the air-out mode (shown in Figure 2) that heating air-valve 13 cuts out downside path R5, defogger air-valve 14 cuts out defroster 22; Heating air-valve 13 opens upside path R4 and downside path R5, defogger air-valve 14 and cuts out the defrosting of air outlet 23/blow pin pattern (shown in Figure 1); Upside path R4 opened by heating air-valve 13 and the blowout pattern up and down of defroster 22 closed by downside path R5, defogger air-valve 14; The defrosting mode that heating air-valve 13 cuts out downside path R5, defogger air-valve 14 cuts out air outlet 23; And heating air-valve 13 close upside path R4 blow the blowout patterns such as pin pattern.
Next, the service condition of the air conditioner for vehicles 1 formed as described above is described.To rear side flowing and by evaporator 10 after the air brought from blowing unit flows into cold air passage R1 from the air introducing port 21 of housing 15, thus cooled.Set according to the rotational angle of air mixing air-valve 12 amount of air flowing into warm braw path R2 from cold air passage R1, the air flow in warm braw path R2 is heated by heating core 11.
Now, blowout pattern for the defrosting shown in Fig. 1/blow pin pattern upside path R4 and downside path R5 is in open mode like that when, warm braw from warm braw path R2, close to continuously, is therefore guided into the cold wind introducing side of air blending space R3 by the plate-like portion 13f of heating air-valve 13 and the upper end of partition wall 28 by plate-like portion 13f.Thus, warm braw can mix fully with cold wind in air blending space R3.
