  • Patent number: 8424141
    Abstract: The present disclosure generally relates to cloth treating machines and methods for operating a cloth treating machine. The controls can supply an appropriate amount of water initially and subsequently based on one or more selected courses or modes of operating the cloth treating machine. For example, the cloth treating machine can supply an appropriate amount of water to a steam generator initially based on a selected course. The steam generator can use the water to generate steam to sanitize and de-wrinkle clothes placed inside a cabinet of the cloth treating machine. During operation, a sensor can sense the level of the water inside the steam generator. An appropriate amount of water can then be re-supplied subsequently based on the selected course or sensed water level, repeatedly. The operation of the cloth treating machine can improve efficiency by reducing the time taken to supply water and generate steam.
