Description

本発明は、室内機ないしは室外機の結露水により、熱交換器の冷却を行うことを可能とする空気調和機に関するものである。   The present invention relates to an air conditioner that can cool a heat exchanger with dew condensation water of an indoor unit or an outdoor unit.

従来の空気調和機としては、例えば図３に示すように、室内機の熱交換器には冷房運転時に結露水が付着するため、結露水を流化させるようにしているが、その結露水は熱交換器の下に配置されたドレンパンに受けた後、排出口に結合されたドレンホースを通して室外に排水するようになっている（例えば特許文献１参照）。   As a conventional air conditioner, for example, as shown in FIG. 3, the condensed water adheres to the heat exchanger of the indoor unit during the cooling operation. After being received by a drain pan disposed under the heat exchanger, it is drained to the outside through a drain hose coupled to a discharge port (see, for example, Patent Document 1).

図３は、前記公報に記載された従来の空気調和機の要部側断面を示すものである。図３に示すように、室内機１と、ドレンパン２と、排出口３と、ドレンホース４と、室外機５（本発明の特徴を表すのに適した範囲で示す）から構成されている。
実開平０５−７３４１６号公報 FIG. 3 shows a sectional side view of a main part of a conventional air conditioner described in the publication. As shown in FIG. 3, it is comprised from the indoor unit 1, the drain pan 2, the discharge port 3, the drain hose 4, and the outdoor unit 5 (it shows in the range suitable for showing the characteristic of this invention).

When it is introduced into the chamber and sprayed onto the outdoor heat exchanger from the blowout portion on the bottom surface of the discharger, the dew condensation water evaporates, and the temperature of the outdoor unit side heat exchanger can be lowered by the evaporation heat.

第２の発明は、暖房運転時に室外機側熱交換器付着した結露水を室外に排出するのではなく、室外機側排水口から接続されたドレンホース周囲に備えたヒーター器により、熱に
より結露水を気化させ、室内機側排水口より室内機側に気化状態の結露水を導入させ、吹出し口より空調を制御する風とともに気化状態の結露水を飛散させることにより、室内を加湿させることができる。 The second invention does not discharge the condensed water adhering to the outdoor unit side heat exchanger during heating operation to the outside, but condenses due to heat by a heater provided around the drain hose connected from the outdoor unit side drain port. Vaporizing water, introducing vaporized condensed water to the indoor unit side from the indoor unit side drain outlet, and humidifying the room by scattering the vaporized condensed water together with the wind that controls the air conditioning from the outlet. it can.
