Abstract

PURPOSE:To prevent the overflow of a condensed water from a storage tank by providing such a constitution as raising an elevator cage to an upper position to exhaust the condensed water within a flexible water pipe when the cage is operated in a lower position for a determined time or more. CONSTITUTION:A condensed water W generated from an air conditioner 5 is run into a storage tank 7 and a flexible water pipe 9 and stored therein. When an elevator cage 4 is operated toward an upper position under this condition, the water level of the condensed water W within the flexible water pipe 9 is placed above an exhaust port 8, and the condensed water W is exhausted from the flexible water pipe 9 to the exhaust port 8. When the operation of the cage 4 in a lower position for a determined time or more is confirmed based on the signals of a cage position detecting means and a time limit measuring means, a control means controls a cage operation control means to raise the cage 4 to the upper position. Thus, in this case also, the condensed water W within the flexible water pipe 9 is exhausted to the exhaust port 8, and the overflow of the condensed water W from the storage tank 7 is prevented.
