Air conditioner for vehicles

An air conditioner for a vehicle having a passenger compartment, said air conditioner comprising:

• a case for introducing conditioned air to said passenger compartment;
• a cooler disposed in said case, for cooling air passing therethrough;
• a heater, disposed on a downstream side of said cooler in said case, for heating air passing therethrough;
• a warm air passage formed at a downstream side of said heater in said case, through which warm air passes;
• a cool air passage, through which said cooled air passes, formed in parallel with said warm passage and an upper side in said case;
• a cool air/warm air mixing chamber formed at as downstream side of said cool air passage and said warm air passage, for mixing said cool air from said cool air passage and warm air from said warm air passage;
• an air outlet passage formed at a downstream side of said cool air/warm air mixing chamber, for introducing air from said cool air/warm air mixing chamber into said passenger compartment;
• and
• a sliding door positioned at an upstream side of said cool air passage and said warm air passage and being slidable in a crossing direction which is proximate to and generally parallel to inlets of both said cool air passage and said warm air passage, for controlling a ratio between a volume of air flowing to said warm air passage and a volume of air flowing to said cool air passage;
• wherein
• said sliding door slides vertically so as to incline with respect to the airflow direction in such a manner that an upper portion of said sliding door is located at the most air upstream side.

• a heater, disposed on a downstream side of said cooler in said case, for heating air passing therethrough;
• a warm air passage formed at a downstream side of said heater in said case, through which warm air passes, formed at a lower side in said case,
• a cool air passage, through which said cooled air passes, formed in parallel with said warm air passage at a downstream side of said cooler in said case and at an upper side in said case,
• a cool/warm air mixing chamber formed at a downstream side of said cool air passage and said warm air passage, for mixing said cool air from said cool air passage and warm air from said warm air passage, and
• an air outlet passage formed at a downstream side of said cool air/warm air mixing chamber, for introducing air from said cool air/warm air mixing chamber into said passenger compartment;
• and
• a sliding door positioned between said cooler and said heater and being slidable in a crossing direction which is proximate to and generally parallel to inlets of both said cool air passage and said warm air passage for controlling a ratio between a volume of air flowing to said warm air passage and a volume of air flowing to said cool air passage;
• wherein
• said sliding door slides vertically in such a manner that an upper portion of said sliding door is closest to said cooler.
