  • Patent number: 7845197
    Abstract: A high efficiency triple pass tunnel finisher includes an articulated spraying function for allowing steam to effectively penetrate a garment. The tunnel finisher can be used for the laundering of shirts, pants, and jackets. The tunnel finisher includes hot air chambers and a steam chamber that can include two rows of steam injectors located at a 45° angle in relation to the walls of the module. The steam chamber has a lower pressure than the hot air chambers, creating an air pressure differential. The hot air chambers are positively pressurized, preventing the relatively cooler air of the steam chamber from entering the chamber. The pressurization prevents heat loss, allowing the finisher to be more efficient, while increasing the temperature at which the garments exit the steam chamber. This leads to faster drying times, less garment wrinkling, and reduced dwell time for a garment with a high quality appearance.

  • Publication number: 20090038084
    Abstract: A washing machine that is capable of providing a stable washing mode even when a washing-related device is abnormal during a washing operation is disclosed. When a steam generation unit, which generates high-temperature steam into a drum, is abnormal, the operation of the steam generation unit is interrupted, and an operation for driving a washing heater mounted in a tub is performed, or an operation for driving a drying unit, which supplies high-temperature dry hot air into the drum, is performed. A steam substituting algorithm is provided when the steam generation unit is abnormal during the operation using the high-temperature steam. Consequently, the interruption of the washing operation due to the abnormal steam injection function is prevented, and therefore, the reliability of the product is improved while the inconvenience of use is minimized.

  • Publication number: 20080250573
    Abstract: The present invention relates to a method for controlling a time period display at the steam spray type washing machine with a steam generator for washing laundry by using a high temperature steam, in which a preliminary set time required for display in the steam spray cycle is determined, not only with reference to a set temperature, but also with reference to a laundry amount, to minimize an error between the time displayed and an actual time. According to this, since a difference between the preliminary set time displayed in the steam spray cycle and the actual time reached to the set temperature is small, there will be no error which is liable to make the user misunderstood that the washing machine is out of order, According to this, reliability of the product, and convenience of the user is enhanced.
