PURPOSE: To improve the workability of attaching work of a funnel-shaped hopper, receiving drain after washing a heat exchanger, to the lower surface of the casing of an air-conditioning machine and improve closely contacting property between the hopper and the heat exchanger without generating gap between them even when the heat exchanger is provided with any configuration and size.
CONSTITUTION: A hopper 6 is constituted of a soft material and can be deformed arbitrarily whereby the hopper 6 can be attached to a casing 22 while being contacted closely to the easing in accordance with the configuration and the size of the casing 22. On the other hand, the hopper can be attached to and removed from the easing easily by using a detachable engaging unit 24.
