  • Patent number: 5548980
    Abstract: A bulged washing tub for a low frequency vibration type washing machine is disclosed. The side wall of the washing tub is outwardly bulged so that this side wall meets with the bottom of the washing tub at an obtuse angle and smoothly guides the heart type or scroll type water current in the washing tub. A plurality of friction prominences of the horizontal stripe type are provided on the inner surface of the outward bulged side wall. The prominences give frictional force to clothes when the clothes are rubbed against them while coming up and going down along with the water current in the washing tub. The frictional force caused by the prominences causes a so-called washboard effect and makes the clothes cleaned as if they were manually washed using a washboard.

  • Patent number: 5432969
    Abstract: A washing method and a washing apparatus capable of obtaining a washing or cleaning effect by mechanical energy obtained by cavitation phenomena or nonlinear oscillation of micro air bubbles generated during the resonance of a multi-phase medium using low frequency waves. The resonance phenomenon becomes accelerated and uniform by virtue of the injection of air bubbles in the tub or the provision of a sonic or ultrasonic oscillation unit, thereby enabling a superior washing performance to be obtained. Since the present invention eliminates use of any pulsator, it is possible to considerably reduce the phenomenon that clothes get twisted or tangled. As a result, few damage of clothes is generated. Moreover, the electric power consumption in washing or cleaning is greatly reduced.

    Abstract: In a unified washing-drying machine, the use of conventional drying means is eliminated and, instead, an electromagnetic heating system is provided at an appropriate place in the unified washing-drying machine as a means to thermally evaporate the remaining moisture in the washed fabrics during the drying cycle. A high-pressure air system with the air nozzle assemblies imbedded on the agitator is installed in the unified washing-drying machine such that the high-pressure air flow from the air nozzle assemblies can float the washed fabrics to have the evaporated steam or water vapor removed efficiently. Also, the high-pressure air flow can have the washed fabrics circulate and tumble well to prevent wrinckles from setting on the washed fabrics. Thus, with the invented unified washing-drying machine contineous, uninterrupted cleaning and drying cycles can be achieved with the additional benefit of saving space by eliminating an extra dryer installment as in a conventional laundry system.

    Abstract: An apparatus and process are described herein for positioning the pile threads found on textile webs manufactured from synthetic fibers which become pliable upon exposure to heat. Means are provided for first routing the textile web through heating means which generally would be a hot water bath. The pile threads are softened by the heat of the hot water bath and become sufficiently pliable as to enable them to assume any position. Because of their buoyancy in water the pile threads tend to orientate themselves perpendicular to the web backing. In order to maintain the pile threads perpendicular until given a chance to cool, the web is removed from the heating apparatus in substantially a horizontal plane. Suction means are provided to cool the textile web as it leaves the heating portion of the apparatus thereby speeding up the set time of the piles. The suction means can also be used to remove a substantial portion of the hot water saturating the textile web.

  • Patent number: 3937236
    Abstract: The ultrasonic cleaning device includes an ultrasonic radiation insulated container for holding a cleaning detergent. A first perforated basket for holding medical or dental tools is carried within the container. The open end of the container is closed by a cover having a peripherally attached rubber gasket and having its bottom side molded with waffle-like indentations for reflecting and/or absorbing ultrasonic radiation. The container and first perforated basket are sized such that one or more baskets can be carried on top of the first basket or, in the alternative, can be fitted with a stainless steel template having a pair of openings for receiving a glass container. The ultrasonic cleaning device is adapted with an automatic timer and a voltage regulator for varying the voltage input which, in turn, varies the ultrasonic frequency introduced into the cleaning detergent. The device is designed to produce a frequency of about one megacycle and can complete the cleaning cycle within 5-15 minutes.
