問題があった。Conventional configuration and its problems Generally, in a ceiling-mounted or embedded air conditioner, if drain water cannot be drained naturally, drain water is stored in a drain pan and the forced drainage device is operated at a position where the water level rises. The normal method is to let it drain. Further, when the air conditioner is stopped by the operation switch, there is a problem that the drain water remains accumulated in the drain pan from the above device, the drain water has to be re-evaporated, and a bad odor is generated.
発明の目的 そのため本発明は、上述した問題点に鑑みドレンパンに
溜ったドレン水の再蒸発，作業や、悪臭の発生を防止す
ることを目的としているものである。Therefore, in view of the above-mentioned problems, the present invention has an object to prevent re-evaporation of drain water accumulated in a drain pan, work, and generation of a bad odor.
発明の構成 この目的を達成するため本発明は、運転スイッチによる
空気調和機の停止後、所定時間排水装置に強制的に通電
してドレンパンのドレン水を強制排水するようにしたも
のである。In order to achieve this object, the present invention is to forcibly energize the drainage device for a predetermined time after the air conditioner is stopped by the operation switch to forcibly drain the drain water of the drain pan.
実施例の説明 以下、本発明の一実施例を図面と共に説明する。第１

調和機の電気回路及び排水装置である。Description of Embodiments An embodiment of the present invention will be described below with reference to the drawings. First
FIG. 2 and FIG. 2 are an electric circuit and a drainage device of an air conditioner having a drain water drainage device of the present invention.

る。SW is an operation switch that controls the operation of the air conditioner,
An electromagnetic contactor 52c for the compressor that drives the compressor CM is provided at the contact c.
And an indoor blower FM are connected, and a contact b is connected to a time delay relay T that operates for a fixed time after energization. PM is a drain pump motor that constitutes a drainage device, and is connected to a power source in series with a float switch F S that is turned on and off according to the water level of the drain water Y in the drain pan D. On the other hand, the contact T a of the time delay relay T is connected in parallel with the float switch F S.
上記構成において、運転スイッチSWは運転側すなわち、
接点ｃに接続されているときは圧縮機用電磁接触器52C

内送風機FMにも電圧が印加される。In the above configuration, the operation switch SW is on the operation side, that is,
When connected to contact c, electromagnetic contactor for compressor 52C
A voltage is applied to the compressor CM, and the compressor CM is in an operating state. In addition, the voltage is also applied to the indoor blower FM.
このとき、ドレン水Ｙの水位がフロートスイッチFSの作
動位置まで上昇していればドレンポンプモータPMに電圧

る。At this time, if the water level of the drain water Y has risen to the operating position of the float switch F S , a voltage is applied to the drain pump motor PM to bring it into an operating state and the drain water Y is forcibly discharged.
逆に運転スイッチSWが停止側すなわち、接点ｂに接続さ

発や悪臭の発生が防止されるものである。Conversely, when the operation switch SW is at the stop side, that is, when it is connected to the contact b, no voltage is applied to the compressor electromagnetic contactor 52C and the compressor stops. At that time, a voltage is applied to the time delay relay T, its contact Ta is closed and a voltage is applied to the drain pump motor PM, and it is operated only for a predetermined time regardless of the operation of the float switch F S to forcibly drain the drain water. . Therefore, when the operation is stopped, the water is forcibly drained every time, so that the re-evaporation and the generation of the bad smell are prevented.

It does not remain accumulated, and there is no re-evaporation of drain water or odor. Also, by stopping the drain water at the low water level of the drain pan,
The electricity to the drainage device is reduced during re-operation, and the effect of preventing wasteful operation can be obtained.
