PROBLEM TO BE SOLVED: To inhibit draft resistance of air flowing in an air-conditioning case and improve the mixing ability between cool air and hot air.SOLUTION: A vehicle air conditioning unit includes a blower 20 having a first fan 21, which is disposed at the airflow downstream side of an evaporator 16 and a heater core 18, suctions cooling air cooled by at least the evaporator, and blows the cooling air to air outlets 121-123, and a second fan 21 which suctions hot air heated by at least the heater core 18 and blows the hot air to the air outlets 121-123. A mixing space M, in which air sent from the fans 21, 22 are mixed, is provided between the fans and the air outlets in an air conditioning case 12.SELECTED DRAWING: Figure 2
【課題】空調ケース内を流れる空気の通風抵抗を抑制するとともに、冷風と温風の混合性を向上する。【解決手段】蒸発器16およびヒータコア18の空気流れ下流側に配置され、少なくとも蒸発器で冷却された冷風を吸い込んで吹出口121〜123へ吹き出す第1ファン21と、少なくともヒータコア18で加熱された温風を吸い込んで吹出口121〜123へ吹き出す第2ファン21を有する送風機20と、を備え、空調ケース12には、複数のファンと吹出口の間に、複数のファン21、22の各々から送出される空気を混合する混合空間Mが設けられている。【選択図】図2
