Abstract
An air conditioning apparatus for an automotive vehicle is comprised of a heater core and a mix door assembly installed in a case. The mix door assembly is detachably installed in the case through an opening formed at a side wall of the case. The mix door assembly is constituted by a housing, a mix door and a slide mechanism. The slide mechanism is arranged to slide the mix door according to a received rotational force to vary a ratio of warm air quantity and cool air quantity.
Claims17
An air conditioning apparatus for an automotive vehicle, comprising:
- a case;
- a heater core installed in said case;
- and
- a mix door assembly detachably installed in said case through an opening formed at a side wall of said case, said mix door assembly varying a ratio of a quantity of air passing through said heater core and a quantity of air bypassing said heater core, said mix door assembly comprising
- a housing,
- a mix door installed to the housing,
- a slide mechanism installed to the housing, the slide mechanism receiving a rotational force and sliding the mix door with respect to the housing according to the received rotational force to vary the ratio.
An mix door assembly detachably installed in a case of an air conditioning apparatus for an automotive vehicle, the case defining an air conditioning passage, said mix door assembly comprising:
- a housing having an opening which generally corresponds to a cross section of the air conditioning passage:
- a door installed in said housing and partly closing the opening, said door sliding in said housing to change a closed portion of the opening;
- and
- a slide mechanism comprising a rack integrally formed on a surface of said door and a pinion rotatably supported to the side plates, the pinion being engaged with the rack, the pinion receiving a rotational force and sliding the door according to the received rotational force.
A method for assembling an air conditioning unit of an air conditioning apparatus for an automotive vehicle, the method comprising the steps of:
- preparing a mix door assembly which has been previously assembled by assembling a mix door and a slide mechanism including a pinion gear into a housing and by installing a driving device to a side wall of the housing;
- installing an evaporator and a heater core at predetermined positions in a case;
- inserting the mix door assembly into the case from an opening formed at a side wall of the case;
- and
- closing the opening of the case by a cover and fixing the cover to the case.
A method for assembling an air conditioning unit of an air conditioning apparatus for an automotive vehicle, the method comprising the steps of:
- assembling a mix door, a slide mechanism, and an evaporator with the housing;
- installing a heater core to a case;
- inserting the mix door assembly with the evaporator to the case through a case opening;
- and
- connecting a cover plate with the case to cover the case opening;
- and
- engaging a gear for transferring the rotational force generated by the driving device 23 to the slide mechanism.
An air-mix door assembly installed in a case of an air conditioning apparatus for a vehicle, said air-mix door comprising:
- a housing comprising a frame and a pair of side plates, the frame defining an opening through which air flowing in the case passes;
- a door slidably supported to the side plates, said door sliding along the frame to change a closing portion which closes a part of the opening;
- and
- a slide mechanism comprising a rack integrally formed on a surface of said door and a pinion rotatably supported to the side plates, the pinion being engaged with the rack and being rotated by receiving a rotational force to slide said door.
