Abstract
The present invention is directed towards a removable heat exchanger for a fabric treating machine. The machine generally includes a perforated spin tub and an imperforate outer shell. In one embodiment the heat exchangers, which are removably mounted to an inner surface of the outer shell, are guided during installation and removal by guide clips. Spacers maintain the heat exchangers a predetermined distance from the inner surface of the outer shell. Retainer clips are provided to releasably retain the heat exchanger in position relative to the spin tub during operation of the machine. In a second embodiment the heat exchangers, which are mounted within side pockets provided by the outer shell. In both the first and second embodiments, the heat exchangers are held in place by jacking bolts. The removable heat exchanger of the present invention improves upon welded-in-place internal heat exchangers and external heat exchangers.
