  • Patent number: 9057527
    Abstract: A range hood is provided that allows the user to select between venting to the exterior of a kitchen space versus recirculating air that is drawn over e.g., a cook top. Features are provided whereby the user can readily switch between such options for gas flow. A filter can also be provided whereby the user can readily select between different filter media depending upon the mode of gas flow selected.

  • Patent number: 8463448
    Abstract: An energy consuming device comprises a power consuming feature/function and a controller operatively connected to the power consuming feature/function. The controller is configured to operate the device including the power consuming feature/function in one of a plurality of operating modes, including at least a normal operating mode during an associated off-peak demand period of an associated energy supplying utility and an energy savings mode during an associated peak demand period of the associated energy supplying utility. The controller is configured to provide a user a grace period during the associated peak demand period to allow the user to change the operating mode of the power consuming feature/function from the energy savings mode to another operating mode including the normal operating mode thereby allowing additional use of the power consuming feature/function during the associated peak demand period.

  • Patent number: 8381714
    Abstract: A gas burner for a cooking appliance having a base portion and a side wall extending from the base portion. A cap is disposed on the side wall. The cap includes a substantially conical interior surface facing the base portion. The substantially conical interior surface is configured to substantially eliminate creation of turbulent flow eddies in a gaseous fuel mixture passing through the gas burner.

  • Patent number: 8190302
    Abstract: A system for reducing peak power usage in a cooking appliance having an oven cavity therein is provided. The system includes at least one power consuming unit with at least two separately controllable elements, a user adjustable electromechanical switching device for controlling energization of the at least one power consuming unit, a control configured to receive and process a utility state signal indicative of the current state of an associated utility; and an element switching device responsive to the control and configured to selectively enable and disable energization of one of the elements in response to the utility state signal.
