Abstract: An adjustable agitation system for an automatic washing machine includes a lost motion fluid drive connection between the input drive member and the agitator so that agitator oscillates through a lesser arc than the input drive member. The fluid drive is formed by pockets in the agitator skirt and corresponding paddles on the drive member skirt. The spacing of the drive member and agitator is varied to vary the differential between the drive member oscillation arc length and the agitator oscillation arc length. A connection member engages the input drive member and is selectively engageable with the agitator to connect the input drive member and agitator for conjoint oscillation.

Abstract: In a self-contained air conditioner unit of the reversible refrigeration system type having cooling and heating cycles, a no-drain heat pump is provided wherein in the heating cycle, water collected on the outdoor heat exchanger operating as the system evaporator is transferred by a condensate disposal system to the indoor section. The condensate is atomized and directed into the indoor air flow and against the relatively warm indoor heat exchanger operating as the condenser to humidify the air. Control means are provided that prevent the condensate disposal system from directing condensate into the indoor air flow during the cooling cycle.

Abstract: The present invention relates to a self-contained air conditioning unit including a reversible refrigeration system and more particularly to a control system having a plurality of sensing means that are effective in maintaining operation of the unit in a heat pump mode when the ambient and the surface temperature of selected refrigeration components are above a preselected frosting temperature, and to energize a heating means to provide uninterrupted heating when the ambient and surface temperatures sensed are below a preselected frosting level which terminates compressor operation.

Abstract: The present invention relates to a self-contained air conditioning unit including a reversible refrigeration system and more particularly to a control system having a plurality of sensing means that are effective in maintaining operation of the unit in a heat mode by use of a supplemental heater when the ambient and the surface temperature of selected refrigeration components are above a preselected frosting temperature, and a secondary heater when the system is in a defrost mode.

Abstract: A control for a self-contained refrigeration system air conditioner unit having a heating and cooling operation. The control provides for defrosting the evaporator and for supplying supplemental heat under selected temperature conditions. A lack of heating capacity by the air conditioner in the heating operation when the outdoor temperature is below a predetermined temperature is supplemented by a first and second heater in combination with the air conditioner refrigeration system heating operation.
