Cooking temperature and power control
First Claim
1. A system for controlling the power delivered to cookware by a power control system that comprises a user-manipulated heating control user interface that is adapted to be turned up and turned down by the user to a particular heating control user interface set point within an operating range, where one or more elements are directly or indirectly heated by the power, the system comprising:
- a system for providing information about the temperature of a heated element; and
a controller that derives from the heating control user interface set point a desired cookware temperature set point, and that, over at least a first portion of the operating range that encompasses the boiling range, also derives from the heating control user interface set point a maximum limit of the power that can be delivered to the cookware to maintain the cookware at the desired cookware temperature set point;
wherein the maximum power limit over the first portion of the operating range increases as the control is turned up.

Abstract
A system and method for controlling the power delivered to cookware by a power control system that comprises a heating control user interface that is set by the user to a particular heating control user interface set point within an operating range. A controller derives from the heating control user interface set point a desired cookware temperature set point, and, over at least a first portion of the operating range that encompasses the boiling range, also derives from the heating control user interface set point a maximum limit of power that can be delivered to the cookware to maintain the cookware at the desired cookware temperature set point. The maximum power limit varies monotonically over the first portion of the operating range.

1. A system for controlling the power delivered to cookware by a power control system that comprises a user-manipulated heating control user interface that is adapted to be turned up and turned down by the user to a particular heating control user interface set point within an operating range, where one or more elements are directly or indirectly heated by the power, the system comprising:
-
a system for providing information about the temperature of a heated element; and a controller that derives from the heating control user interface set point a desired cookware temperature set point, and that, over at least a first portion of the operating range that encompasses the boiling range, also derives from the heating control user interface set point a maximum limit of the power that can be delivered to the cookware to maintain the cookware at the desired cookware temperature set point; wherein the maximum power limit over the first portion of the operating range increases as the control is turned up. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18)

19. A system for controlling the power delivered to cookware by a power control system that comprises a user-manipulated heating control user interface that is adapted to be turned up and turned down by the user to a particular heating control user interface set point within an operating range, where one or more elements are directly or indirectly heated by the power, the system comprising:
-
a system for providing information about the temperature of a heated element; a controller that derives from the heating control user interface set point a desired cookware temperature set point, and that, over a first portion of the operating range that is from about 100°
C. to at least about 120°
C., also derives from the heating control user interface set point a maximum limit of the power that can be delivered to the cookware to maintain the cookware at the desired cookware temperature set point, wherein the maximum power limit defines an increasing curve over the first portion of the operating range, wherein the curve defines a relatively steep slope proximate both the lowest and the highest temperatures of the first portion of the operating range, and a less steep slope over the rest of the first portion of the operating range; andwherein the controller, over a second portion of the operating range that comprises temperatures below the lowest temperature of the first portion of the operating range and temperatures above the highest temperature of the first portion of the operating range, controls the power delivered to the cookware to maintain the desired cookware temperature. - View Dependent Claims (20)

21. A method of controlling the power delivered to cookware by a power control system that comprises a user-manipulated heating control user interface that is adapted to be turned up and turned down by the user to a particular heating control user interface set point within an operating range, where one or more elements are directly or indirectly heated by the power, the method comprising:
-
providing information about the temperature of a heated element; deriving from the heating control user interface set point a desired cookware temperature set point; and over a first portion of the operating range that encompasses the boiling range, also deriving from the heating control user interface set point a maximum limit of power that can be delivered to the cookware to maintain the cookware at the desired cookware temperature set point, wherein the maximum power limit is entirely non-decreasing from a lowest temperature of the first portion of the operating range to a highest temperature of the first portion of the operating range.
