Description

【０００１】
【発明の属する技術分野】
本発明は、空気調和機に係わり、より詳細には、暖房運転の立ち上がりを円滑にした構造に関する。
【０００２】
【従来の技術】
従来の空気調和機は、図３で示すように、ベース３０の前面に前面パネル３１を装着して本体を構成し、前記前面パネル３１に前面吸込口３３を形成した吸込グリル３２を着脱自在に設けている。前記前面パネル３１の上面には上面吸込口３４が形成され、前面下部には風向変更板３５ａを備えた吹出口３５が設けられており、前記前面吸込口３３及び前記上面吸込口３４と、前記吹出口３５とを結ぶ空気通路には、垂直部３６ａと、同垂直部３６ａの上端を折曲して後方に傾斜させた後方傾斜部３６ｂとからなる熱交換器３６と、同熱交換器３６で熱交換された空気を前記吹出口３５から室内に送出する送風ファン３７とが設けられている。
【０００３】
暖房運転時、室外機に備えられた熱交換器は室外の空気から熱を吸収する蒸発器として作動し、室内機に備えられた前記熱交換器３６は熱を放出する凝縮器として作動するようになっている。
【０００４】
しかしながら、暖房運転の開始時、室内機に備えられた前記熱交換器３６は、温度が上昇するまでにある程度の時間を要する一方、前記前面吸込口３３及び前記上面吸込口３４から吸込まれた室内の空気は、前記熱交換器３６を一旦通過して加熱されるのみなので充分に温度が上昇せず、前記吹出口３５から暖かい空気が吹出すまでは所定の時間を要することとなっていた。また、室温が設定した温度に達して室外機に備えられた圧縮機の運転が低速に切換えられたような場合、前記吹出口から吹出される空気の温度も低下し、使用者に不快感を与えることとなっていた。
【０００５】
【発明が解決しようとする課題】
本発明は上記問題点に鑑み、暖房運転の開始時、吹出口から暖かい空気が吹出されるまでの時間を極力低減するとともに、吸込まれた空気を充分に加熱して暖房運転を円滑に行うことのできる空気調和機を提供することを目的とする。
【０００６】
【課題を解決するための手段】
本発明は上記課題を解決するため、本体の前面上部に前面吸込口を、上面前部に上面前部吸込口を夫々設けるとともに、上面後部に上面後部吸込口を設け、下面前部に上下風向変更板を備えた前部吹出口を、下面中央に上下風向変更板を備えた後部吹出口を夫々設け、これら吸込口と吹出口とを結ぶ空気通路に、同空気通路の中央部から下位部までを前後に区画し、前記前面吸込口及び前記上面前部吸込口と前記前部吹出口とを結ぶ前部空気通路と、前記上面後部吸込口と前記後部吹出口とを結ぶ後部空気通路とを形成する仕切体を設け、前記前部空気通路に前部熱交換器と前部送風ファンとを、前記後部空気通路に後部熱交換器と後部送風ファンとを夫々設ける一方、前記仕切体の上方に、第一の状態で前記前部空気通路と前記後部空気通路とを遮蔽し、第二の状態で前記前部空気通路と前記後部空気通路とを連通させる一方、前記上面後部吸込口を遮蔽する開閉体を設けてなり、
暖房運転時、前記開閉体を前記第二の状態に設定するとともに、前記上下風向変更板により前記前部吹出口を遮蔽して、前記前面吸込口及び前記上面前部吸込口から吸込まれた空気が前記前部熱交換器と前記後部熱交換器とを経て前記後部送風ファンにより前記後部吹出口から室内に送出されるようにする一方、前記前部熱交換器で加熱された空気を、更に前記後部熱交換器で再度加熱し昇温させるようにした構成となっている。
【０００７】
また、前記開閉体が、上端に設けた軸を中心として上方に回動することにより、前記前部空気通路と前記後部空気通路とを連通させるとともに、前記上面後部吸込口を遮蔽し、下方に回動することにより前記前部空気通路と前記後部空気通路とを遮蔽する構成となっている。
【０００８】
また、冷房運転時、前記開閉体が、前記前部空気通路と前記後部空気通路とを遮蔽する構成となっている。
【０００９】
更に、暖房運転時、室温が設定された所定の温度に達した際は、前記開閉体により前記前部空気通路と前記後部空気通路とを遮蔽し、これらのいずれか一方で暖房運転を継続するようにした構成となっている。
【００１０】
【発明の実施の形態】
以下、本発明の実施の形態を、添付図面に基づいた実施例として詳細に説明する。
図１は本発明による空気調和機を示す断面図であり、図２は暖房運転時の空気の流れを示す断面図である。
本発明による空気調和機は、図１で示すように、前面が開放されたベース１に、後面が開放された前面パネル２を装着して本体を構成している。前記前面パネル２の前面上部には複数の横桟による前面吸込口７ａが、上面前部には上面前部吸込口７ｂが夫々形成され、上面後部には上面後部吸込口８が形成されている。本体の下面前部には、複数の上下風向変更板９ａと左右風向変更板９ｂとを備えた前部吹出口９が設けられ、下面中央には複数の上下風向変更板１０ａと左右風向変更板１０ｂとを備えた後部吹出口１０が夫々設けられている。前記上下風向変更板９ａと前記上下風向変更板１０ａとは、回動することにより前記前部吹出口９及び前記後部吹出口１０から吹出される空気を上下方向に偏向する一方、これら吹出口９及び１０を夫々閉鎖できるようになっている。
【００１１】
前記本体の複数の吸込口及び複数の吹出口とを結ぶ空気通路には、同空気通路の中央部から下位部までを前後に区画し、前記前面吸込口７ａ及び前記上面前部吸込口７ｂと前記前部吹出口９とを結ぶ前部空気通路５と、前記上面後部吸込口８と前記後部吹出口１０とを結ぶ後部空気通路６とを形成する仕切体３が設けられている。また、同仕切体３の上方には、前記前部空気通路５と前記後部空気通路６とを遮蔽あるいは連通させる一方、前記上面後部吸込口８を遮蔽することのできる開閉体４が設けられている。同開閉体４は上端に設けた軸４ａにより回動自在に軸支され、上方に回動すると前記前部空気通路５と前記後部空気通路６とを連通させる一方、前記上面後部吸込口８を遮蔽し、下方に回動すると前記前部空気通路５と前記後部空気通路６とを遮蔽するようになっている。
【００１２】
前記前面吸込口７ａ及び前記上面前部吸込口７ｂと前記前部吹出口９とを結ぶ前記前部空気通路５には、垂直部１１ａと、同垂直部１１ａの上端を折曲して後方に傾斜させた後方熱交換器１１ｂとからなる前部熱交換器１１と、同前部熱交換器１１で熱交換された空気を前記前部吹出口９から室内に送出する前部送風ファン１３と、前記前部熱交換器１１から滴下する凝縮水を受ける前部露受皿１５とが夫々設けられ、前記上面後部吸込口８と前記後部吹出口１０とを結ぶ前記後部空気通路６には、後方に傾斜した後部熱交換器１２と、同後部熱交換器１２で熱交換された空気を前記後部吹出口１０から室内に送出する後部送風ファン１４と、前記後部熱交換器から滴下する凝縮水を受ける後部露受皿１６とが設けられている。
【００１３】
次に、上記した空気調和機の動作について説明する。冷房運転においては、図１で示すように、前記上下風向変更板９ａと前記上下風向変更板１０ａとが下方に回動して前記前部吹出口９と前記後部吹出口１０とを夫々開放するようになっている。また、前記開閉体４により前記前部空気通路５と前記後部空気通路６とは遮蔽されるようになっている。前記前面吸込口７ａ及び前記上面前部吸込口７ｂとから吸込まれた室内の空気は、前記前部空気通路５に設けられた前記前部熱交換器１１により熱交換され、前記前部送風ファン１３により前記前部吹出口９から室内に送出され、前記上面後部吸込口８から吸込まれた室内の空気は前記後部空気通路６に設けられた前記後部熱交換器１２により熱交換され前記後部送風ファン１４により前記後部吹出口１０から室内に夫々送出されるようになっている。尚、前記前部空気通路５のみで冷房運転を行ったり、前記上下風向変更板９ａにより前記前部吹出口９を閉鎖して、前記後部空気通路６のみで冷房運転を行えるようにもなっている。
【００１４】
次に、暖房運転時の動作について説明する。暖房運転時、図２で示すように、、前記開閉体４が前記軸４ａを中心として上方に回動し、前記前部空気通路５と前記後部空気通路６とを連通させる一方、前記上面後部吸込口８を遮蔽し、また前記上下風向変更板９ａにより前記前部吹出口９が閉鎖されるようになっている。前記前部熱交換器１１と前記後部熱交換器１２とは吸込まれた空気に対し熱を放出して、これを加熱する凝縮器として作動するようになっている。
【００１５】
前記前面吸込口７ａ及び前記上面前部吸込口７ｂから吸込まれた室内の空気は、図２の矢印で示すように、前記前部熱交換器１１により加熱され、ある程度温度が上昇する。続いて開放された前記開閉体４により前記後部空気通路６に流入し、同後部空気通路６に設けられた前記後部熱交換器１２により、更に加熱されて室内を暖房できる充分な温度にまで上昇し、前記後部送風ファン１４により前記後部吹出口１０から室内に送出されるようになっている。吸込まれた空気が前記前部熱交換器１１と前記後部熱交換器１２とで二度に渡り加熱されることにより、暖房運転の開始当初、前記前部熱交換器１１及び前記後部熱交換器１２の温度が充分に上昇していなくても、前記後部吹出口１０からある程度温度の上昇した空気を吹出すことができ、暖房運転を円滑に立ち上げることができるようになっている。また、室外機に備えられた圧縮機の運転が低速に切換えられたとしても、前記後部吹出口１０から吹出される空気の温度が急激に低下することなく暖房運転を継続することができ、運転の切換わりにより使用者に対し不快感を与えてしまうというような不具合を防ぐことができるようになっている。尚、室温が充分に上昇した場合は、前記開閉体４により前記前部空気通路５と前記後部空気通路６とを遮蔽し、これらのいずれか一方で暖房運転を継続することもできるようになっている。
【００１６】
【発明の効果】
以上説明したように、本発明によると、本体内を、仕切体により前後に区画し、これの前面に前部熱交換器と前部送風ファンとを備えた前部空気通路を、後面に後部熱交換器と後部送風ファンとを備えた後部空気通路を夫々形成することにより、暖房運転時、前記開閉体を回動させ前記前部空気通路と前記後部空気通路とを連通させる一方、吸込まれた空気を前記前部熱交換器と前記後部熱交換器とで再度に渡り加熱することにより、暖房運転を円滑に立ち上げることのできる空気調和機となる。
