  • Patent number: 5815961
    Abstract: A clothes treating apparatus and method for subjecting clothes items to moisture, pressure and heat for refreshing and dewrinkling the clothes items. A cabinet defines an interior region for receiving clothes, the interior region having opposed inner side surfaces. A door is hingedly connected to the cabinet for closing the interior region. An inflatable hanger for supporting shirt-like clothes items is disposed within the interior region. A blower selectively inflates the inflatable hanger for pressing the shirt-like clothes item against the cabinet inner side surfaces. A steam generation means is provided for introducing moist air into the cabinet for humidifying the clothes item disposed therein. A heater and fan supply heated air into the interior region for drying the shirt-like clothes items disposed therein. During the dewrinkling cycle, steam is introduced into the interior region while the inflatable hanger assembly is periodically inflated.

  • Patent number: 5392610
    Abstract: There is disclosed herein a refrigerant container in the form of a bag, or pouch, made from two sheets of multi-layer barrier film material which are heat sealed adjacent their edges to form a closed pouch which has an interior space. The bag may be connected to an access valve provided in a line of a sealed refrigeration system for capturing the refrigerant therefrom. The barrier film material is specially formulated to prevent outward permeation of a refrigerant and to prevent inward permeation of air. A valve system is provided for filling and emptying the bag.

  • Patent number: 5359744
    Abstract: A wash additive dispensing system and method for an automatic washer having a wash additive dispenser disposed on the upper portion of an agitator rotatably mounted within a wash basket. The wash additive dispenser comprises a receiving cup capable of receiving a wash additive and a dispensing cup secured to receive wash additive from the receiving cup. A cover member is disposed above the receiving cup and includes a funnel portion extending down into the receiving cup. During a fill cycle operation, a portion of wash liquid flowing into the wash basket through a water inlet device is channeled into a wash liquid supply conduit secured to the underside of a washer lid disposed above the wash basket. The supply conduit has a drain port positioned above the funnel portion of the cover member such that wash liquid continuously drains into the receiving cup through the funnel portion during the fill cycle.

  • Patent number: 5271251
    Abstract: A vertical axis washer is provided with a rotatable wash basket that has one or more inwardly directed baffles, but no central agitator structure. Surfaces are provided in association with the baffles, which may be in the form of ramps on the bottom wall of the basket, to cause the fabric load within the washer to move up the side of the basket wall and to slide along the baffles in a swirling motion as the basket is accelerated and decelerated during the washing cycle, which causes the fabric to be flexed and rearranged in the basket. This washer construction is particularly suited to be used in conjunction with a concentrated detergent solution wash cycle.

  • Patent number: 5191667
    Abstract: A method of washing fabric in a washer having a wash chamber rotatable about a vertical axis and charged with a detergent solution is provided. The wash chamber is rotated about its vertical axis a number of revolutions sufficient to cause the fabric and detergent solution within the wash chamber to rotate at a speed approximately the same as the wash chamber. The wash chamber is periodically decelerated to cause the fabric and detergent solution to move relative to the wash chamber due to rotational inertia of the fabric and detergent solution. The fabric is caused to tumble within the wash chamber by impinging the fabric on structures in the wash chamber as the fabric is moving relative to the wash chamber. The steps of rotating, decelerating, and tumbling are repeated for a predetermined first period of time. A recirculating spray of concentrated detergent solution is directed on to the fabric during the first period of time as the fabric is rotating with and tumbling in the wash chamber.
