御構造としては、たとえば実開昭57−53301号公
報に示されるようなものがある。BACKGROUND ART Conventionally, as a ventilation circuit control structure of a vertical blowing type air conditioner, there is one as shown in, for example, Japanese Utility Model Application Publication No. 57-53301.
以下、図面を参照しながら説明する。第４図は
従来の空気調和機の通風回路の構成を示してい
る。同図において冷房運転の場合フアン１０４に
吸込まれた風は上吹出口１０２より吹出される。
また暖房運転の場合、フアン１０４に吸込まれた
風は上吹出口１０２から吹出されるとともに開閉
部材１０５の開動作により下吹出口１０３からも
吹出される。 This will be explained below with reference to the drawings. FIG. 4 shows the configuration of a ventilation circuit of a conventional air conditioner. In the figure, in the case of cooling operation, the air sucked into the fan 104 is blown out from the upper outlet 102.
Further, in the case of heating operation, the air sucked into the fan 104 is blown out from the upper outlet 102 and also blown out from the lower outlet 103 by the opening operation of the opening/closing member 105 .
発明が解決しようとする問題点
前記のような従来の構成において冷房運転時も
上下両吹出口より冷風を吹出してやれば冷房効果
が増大するが、下吹出口より低風速、低風量の冷
風を吹出すことは運転開始時以外には逆に冷房フ
イーリングを悪くしたり、また下吹出口周辺の結
露対策が必要というような問題点もあつた。Problems to be Solved by the Invention In the conventional configuration as described above, the cooling effect can be increased by blowing cold air from both the upper and lower outlets during cooling operation, but if cold air is blown at a lower wind speed and volume from the lower outlet, the cooling effect can be increased. There were also problems in that venting air other than at the start of operation adversely affected the cooling feeling and required measures to prevent condensation around the lower air outlet.
本発明は以上の点に鑑みて、熱交換器温度が所
定温度以上でかつ下フアン風量が多い場合すなわ

弱運転時のフイーリング向上、下吹出口周辺の結
露による水洩れ防止を可能とするものである。 In view of the above points, the present invention operates to open the lower outlet when the heat exchanger temperature is higher than a predetermined temperature and the lower fan air volume is large, that is, the upper fan air volume is also large and high cooling capacity is required. Conversely, when the heat exchanger temperature is below the specified temperature and the lower fan air volume is small, the lower air outlet is closed, ensuring high cooling capacity after the start of operation, and improving the feeling during weak operation. This makes it possible to prevent water leakage due to condensation around the lower outlet.

御装置とを設けたものである。Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a control device that increases or decreases the speed of the lower fan in conjunction with the speed of the upper fan of a vertical blow-out type air conditioner;
A fan speed detection device that determines whether the speed is high or low, a pipe temperature sensor that detects the temperature of the heat exchanger,
This device includes an opening/closing member that opens and closes the lower outlet ventilation circuit, and a control device that stops the lower fan in conjunction with the closing operation of the opening/closing member.

を確保するものである。Effects With the above configuration, the present invention closes the lower outlet when the temperature of the heat exchanger is below a predetermined temperature and the speed of the upper and lower fans is low, thereby preventing the cooling feeling from being electrified when the lower air volume is low and lower the outlet. This prevents condensation and ensures high cooling capacity when the vertical fan speed is high.
