Brief description

Fig. 1 is this utility model air conditioner damper arrangement schematic diagram；Fig. 2 is that this utility model blender door drive mechanism is illustrated Figure；Fig. 3 is the front view of blender door；Fig. 4 is the top view of Fig. 3；Fig. 5 is the A-A sectional view of Fig. 3.

Specific embodiment

Disturbed by heater thermal source to solve refrigeration system, using blender door and warm braw core body air inlet air door Structure with sharing an air channel, makes the less effect of air conditioning system volume.In the upper end of air-conditioner shell 1, blower fan 2 is set, should The lower section setting evaporator core 6 of fan outlet, arranges blender door 8 and warm braw core body in the lower section of this evaporator core 7, this warm braw core body is inclined to set, and blender door 8 is in the right side of warm braw core body upper end, in the downside of warm braw core body Setting warm braw core body air inlet air door 9, described blender door has two states, and 1, by vaporizer, cold wind out is closed, this When warm-air drier hot-air mouth out open, 2, fan heater air outlet is closed, and the cold wind air outlet of vaporizer is opened, by evaporating Device cold wind out and out warm braw enters same air channel by warm-air drier, the defrosting with setting on air-conditioner shell respectively of this air channel Air port, blow face air port, blow foot air port and be connected, described defrosting outlet, blowing face air port and blow foot air port and be respectively arranged with defrosting wind Door 3, blow face air door 4 and blow foot air door 5.Described warm braw core body air inlet air door, defroster door, blow face air door and blow foot air door It is known flat board air door.As in Figure 3-5, the horizontal sanction face of this blender door is sector to the structure of blender door, fan-shaped Top is arc honeycomb structured body 16, is respectively provided with Y type elastomer 17 in the both sides of this arc honeycomb structured body, this Y type elastomer Radius be more than arc honeycomb structured body radius, the two ends of described sectored cell structure are individually fixed in two fanning strips 18 Top, blender door axle is located at the circle centre position of described two fanning strips and rotational support is in air-conditioner table body opening, described fan Shape plate and arc honeycomb body structure are PP-TD40 plastics.The blender door of this structure has sealing excellent noise reduction effect and manipulation The little advantage of power.

Evaporator core should make condensed water smoothly discharge horizontal by certain angle of inclination, typically selects 60-80 °, warm braw The setting of core body mainly considers that air-out is smooth and reduces overall volume, and it is advisable with the horizontal 0-50 °.

Blender door and the drive mechanism of warm braw core body air inlet air door opening and closing, because refrigeration and heating can not be entered simultaneously OK, and do not disturbed by the heat of electromotor heat exchange when freezing, warm braw runner should be closed the door, thus above-mentioned two air door should link, I.e. during a door opening, another air door should be closed, and adopt following drive mechanisms for this：One end of driving plate 13 and driving Axle 15 connects, and the other end is hinged with one end of connecting rod 1, and the other end of this connecting rod one is hinged with wobble plate 10, this wobble plate with mix Axle of the air door connects, and in air-conditioner shell hole, the two ends of described drive shaft rotate props up the two ends rotational support of this blender door axle Support in air-conditioner housing hole, one end of drive rod 12 is connected with described drive shaft, this drive rod is hinged with one end of connecting rod 2 14, The other end of this connecting rod two is hinged with rocking arm, and this rocking arm is connected with warm braw core body air inlet axle of the air door, and this warm braw core body enters The two ends of air port axle of the air door are rotatably supported in air-conditioner shell hole, and described driving plate is provided with wire drawing, for driving two to mix Close the opening and closing of air door.

The principle of the opening and closing of this utility model blender door and warm braw core body air inlet air door is, as shown in Fig. 1～2, When blender door is closed warm braw air channel and warm braw core body air inlet air door and is closed, that is, air-conditioner is in refrigeration shape State, now freezes and is not disturbed by the thermal source of warm-air drier.When vehicle needs heating, now, vaporizer does not work, and warm-air drier works Heating, the air outlet of vaporizer should be closed the door by blender door, and the air inlet of warm braw core body is opened, and makes blower fan through vaporizer Wind out fully enters heater cores, and manipulating wire drawing makes 51.6 ° of driving plate rotation counterclockwise, makes to mix by connecting rod one and wobble plate Close axle of the air door and rotate counterclockwise 90 °, blender door is changed into open mode and by vaporizer from closing heater cores air outlet Air outlet is closed, and rotating counterclockwise of drive shaft makes warm braw core body air inlet air door turn clockwise by drive rod and connecting rod two Dynamic 37 ° of air inlets making warm braw core body are opened, and the warm braw of warm-air drier is to Vehicle heating.Described defroster door, blow face air door and Blow foot air door to be each operated alone.The opening and closing of above-mentioned each air door, by being operated respectively manually.Wherein blender door and The outlet air door of warm braw core body can adopt link gear.

Blender door with the on-off action principle of warm braw core body air inlet air door is, vehicle refrigeration state（Warm braw movement Body air intake damper is closed, and warm braw core body air outlet is closed by blender door）Be converted to when heating state, drive is made by wire drawing Rotation that dynamic plate is counterclockwise, drive rod drivening rod rotates clockwise, and warm braw core body air inlet air door is opened, and driving plate passes through pendulum Plate makes blender door axle rotate counterclockwise, and blender door is changed into open mode from closing warm braw core body air outlet, now, empty Adjust evaporator stops operation, warm braw core body is entered through evaporator core by blower fan wind out and absorbs in entrance air channel after heat To defrosting outlet with blow foot air port and send warm braw.Blow face air door, blow the opening and closing of foot air door and defroster door by manually individually controlling, mix Close air door and warm braw core body air inlet air door can also be opened and closed by manually individually manipulating.
