摘要： An idler pulley assembly for tensioning a belt drive for a clothes dryer or other belt driven appliance. The idler pulley assembly provides a spring steel support anchored to a base of the clothes dryer, a Y-shaped bracket connected to the spring steel support and holding an idle pulley at an opposite end. The idle pulley is mounted on an open cross section, C-shaped shaft which is fixed at opposite arms of the Y-shaped bracket. An oil impregnated wick is inserted into the shaft which deposits oil on an inside surface of the idler pulley journaling the shaft.

摘要： A method and apparatus for sequentially operating a refrigeration system with multiple evaporators is provided in which only one evaporator is operated at a time and is run until a detected demand for cooling associated with that evaporator is satisfied, or until a predetermined time period has elapsed which corresponds to the normal run time for that evaporator. If the run time expires prior to the demand for cooling being satisfied, and if demand for cooling by another one of the evaporators is present, then operation of the first evaporator is terminated and the other evaporator is operated. Efficiency enhancements are provided such as prematurely initiating operation of a second evaporator at the conclusion of operation of a first evaporator if it appears that a demand for cooling by the second evaporator will occur within a short period of time following termination of operation of the first evaporator.

摘要： A refrigeration appliance having at least two refrigeration compartments, each compartment having its own access door, is provided wherein there is a first evaporator for the first compartment the first evaporator operating at a first pressure level and a second evaporator for the second compartment, the second evaporator operating at a pressure level higher than the first pressure level. There is a control device for directing refrigerant to a selected one of the evaporators from a condenser and for preventing a flow of refrigerant into the first evaporator when refrigerant is being directed into the second evaporator to cool the second compartment. Around the first compartment is placed insulation having a higher thermal resistance than that placed around the second compartment since the first compartment is kept at a lower temperature that the second compartment. A phase change material may be used in association with one or both of the evaporators.
