  • Patent number: 5961311
    Abstract: A gas burner system including a burner body having a flange providing an annular surface. A removable cap is disposed above the burner body and contacts the annular surface for forming an annular interface with the burner body for closing the burner body. A plurality of ports are provided along the annular interface between the burner body and the cap. A first ignitor is disposed adjacent the annular interface between the burner body and cap. A second ignitor is also disposed adjacent the annular interface between the burned body and cap.

  • Patent number: 5947573
    Abstract: A container for a refrigerator in which the container comprises a pan having an access opening, which is covered by a door pivotally mounted to the pan. The pan is slidably mounted within the refrigerator in a conventional manner. The door has opposing fingers extending from the side edges thereof and a hook extending from the top edge thereof. As the pan is slid outwardly from the refrigerator, the fingers abut liner studs extending from the inner liner of the refrigerator to partially rotate the door from a closed position toward an open position. On the continued sliding of the pan, the hook abuts a sloped surface of the liner to continue the rotation of the door completely into the open position.

  • Patent number: 5928543
    Abstract: The invention is a cooktop having a heating element that is locked in place and held in place by a biasing force to eliminate the rattle of the heating element during normal use and the dislodgement of the heating element during shipping. The heating element comprises a heating coil which is supported on a spider having multiple legs. The heating coils has two terminals which are connected to a receptacle block in the cooktop. The spider has a nose formed on the end of the legs. A biasing device is positioned between the cooktop and the heating coil, preferably a spring mounted to the electrical terminals and abutting the cooktop. The biasing device biases the nose of the spider into a keyway formed in the cooktop to wedge the nose into a locking position relative to the cooktop.

  • Patent number: 5924857
    Abstract: An atmospheric burner is associated with a flame presence sensor and an electrical-discharge ignition device. It is fed via a flow rate control device. Both the ignition device and the flow rate control device are controlled by a microcontroller. A user interface enables the user to select the desired power by sending to the microcontroller a request for altering the flow rate and hence for altering the minimum power deliverable by the burner.

  • Patent number: 5924432
    Abstract: A dishwasher having a fluid recirculation system which operates in a wash mode for spraying liquid onto objects supported on dishwasher upper and lower racks. The dishwasher includes a pump having a pump impeller disposed within a pump chamber for supplying wash liquid to first and second spray devices, associated with the lower rack and upper racks, respectively. The pump impeller draws wash liquid into the pump chamber and imparts a rotary motion to the wash liquid disposed in the pump chamber. A rotatable diffuser or flow director having a plurality of vanes extending into the pump chamber selectively directs the rotating wash liquid toward the spray devices and thereby controls wash liquid recirculation within the dishwasher responsive to the rotational motion of the wash liquid in the pump chamber.

  • Patent number: 5909743
    Abstract: 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.

  • Patent number: 5900070
    Abstract: 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.

  • Patent number: 5884495
    Abstract: 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.
