Patent number: 5918474Abstract: A refrigeration appliance and control system for efficiently operating the evaporator and condenser fan motors of the refrigeration appliance to reduce the total energy consumed by the appliance are disclosed. The control system operates to turn the evaporator fan motor on only after the evaporator has cooled to its operating temperature to avoid premature and inefficient use of the evaporator fan motor. The control system also permits the evaporator fan motor to continue running after the compressor is turned off to utilize the residual cooling capacity of the evaporator. In an embodiment, a secondary control system also operates to turn a condenser fan motor on only after the condenser reaches its operating temperature and operates to turn the condenser fan motor off only after the compressor is turned off and the condenser cools to a shutoff temperature below its operating temperature.Type: GrantFiled: July 15, 1997Date of Patent: July 6, 1999Assignee: Whirlpool CorporationInventors: Jatin C. Khanpara, Ernest C. Pickles

Patent number: 5909743Abstract: A dishwasher pump and automatic purge system which includes a wash impeller supported for rotation within a pump chamber wherein the pump chamber has a main outlet and a sample outlet port. Wash liquid pumped out through the main outlet is recirculated throughout the dishwasher interior wash chamber. A soil collector receives wash liquid through the sample outlet port. The soil collector includes a filter screen for returning filtered wash liquid back into the sump such that soils are retained in the soil collector. Pressure within the soil collector is sensed by a pressure sensor. The soil collector is purged by a drain pump when the pressure within the soil accumulator exceeds a predetermined limit level such that soils are cleared from the collector and the filter screen. When the pressure within the soil accumulator is reduced to below the predetermined limit level, the drain pump is deenergized.Type: GrantFiled: September 10, 1997Date of Patent: June 8, 1999Assignee: Whirlpool CorporationInventors: Edward L. Thies, Roger J. Bertsch, Wilbur W. Jarvis

Patent number: 5910166Abstract: A varying cross-sectional area capillary tube for a refrigeration system. The capillary tube comprises at least a first portion and a second portion. The first portion has a cross-sectional area that is effectively smaller than the cross-sectional area of the second portion. By doing so, any contaminants contained in the refrigerant will deposit themselves within the second portion of the capillary tubes, but because of the increased cross-sectional area, will not clog the capillary tube.Type: GrantFiled: November 25, 1997Date of Patent: June 8, 1999Assignee: Whirlpool CorporationInventors: Alan J. Mitchell, Brent A. Junge

Patent number: 5899083Abstract: A refrigerator having a middle fresh food compartment and a relatively large bottom freezer compartment arranged below the fresh food compartment and a relatively small freezer compartment arranged above the fresh food compartment. The bottom freezer compartment preferably supports a drawer including a frame and a removable bin. Cool air can be supplied to the compartments of the refrigerator by employing a two fan control system such that no electromechanical baffles are required. Alternatively, cool air can be directed to the compartments of the refrigerator by use of a baffle which requires only a single electromechanical device to control air flow into three different compartments. The baffle includes a main rotary damper which can be positioned to provide proportional amounts of chilled air to the three separate compartments based on the degree of cooling required.Type: GrantFiled: March 19, 1998Date of Patent: May 4, 1999Assignee: Whirlpool CorporationInventors: James R. Peterson, Steven J. Kuehl, Michael S. Kauffman, Jim J. Pastryk, Devinder Singh, Richard C. Spears, Jeffrey L. Burk, Donald E. Janke, Li Gong Ling

Patent number: 5900070Abstract: A thermal input system is provided for a dishwasher having an interior wash chamber receiving soiled dishes and wash liquid. A heater is disposed in a sump region of the wash chamber along with a wash pump which operates to recirculate wash liquid through out the wash chamber. A soil collection chamber receives a portion of recirculating wash liquid from the wash pump wherein soils entrained in the wash liquid are captured within the soil collection chamber. A pressure sensor senses fluid pressure within the soil collection chamber. Control means are provided for energizing the heater during a thermal hold period in response to the pressure within the soil collector exceeding a predetermined limit pressure. In particular, the control means operates to sequence the dishwasher through a predetermined period of operation but bypasses the thermal hold cycle when the pressure within the soil collector does not exceed the predetermined limit pressure.Type: GrantFiled: December 23, 1997Date of Patent: May 4, 1999Assignee: Whirlpool CorporationInventors: Wilbur W. Jarvis, Charles P. Deming, Ginger E. Patera, Ryan K. Roth, Edward L. Thies, Kathryn A. Stady

Patent number: 5884495Abstract: The invention is a dehumidifier comprising an adjustable float with a variable height cam surface that is in contact with the actuator of an interlock switch, which controls the supply of power to the refrigeration system of the dehumidifier. The float is rotatably mounted to the collection bucket of the dehumidifier and rotates as the bucket fills with liquid. At a sufficient amount of rotation, the cam surface will no longer be in contact with the actuator of the interlock switch, resulting in the removal of power from the refrigeration system. The float can be laterally adjusted so that a variable height cam surface is aligned with the actuator of the interlock switch to permit the user to vary the liquid level at which the interlock switch is activated to cut off power to the refrigeration system.Type: GrantFiled: October 9, 1997Date of Patent: March 23, 1999Assignee: Whirlpool CorporationInventors: David E. Powell, Christopher M. Thompson
