Abstract

An electric toaster with a toasting chamber for a food item, having radiant heaters arranged on opposite sides thereof, and a microwave generator for internally heating the food item. The radiant and the internal heaters can be controlled separately by the user to achieve a required combination of internal and external temperature/texture.

First claim

1 - 16 . (canceled)

17 . An electric toaster comprising:
a toasting chamber arranged to receive at least one food item to be toasted, the item having opposed major surfaces, a support for supporting the at least one food item at a toasting location within the chamber, a first heater for applying radiant heat to the opposing major surfaces of the at least one food item in the chamber, a second heater for internally heating the at least one food item, and individual user-operable controls for separately controlling the amount of heat applied to the at least one food item by the first and second heaters, respectively.

18 . A toaster according to claim 17 , wherein the first heater comprises fast response infrared heating elements.

19 . A toaster according to claim 18 , wherein the fast-response elements comprise one or more of tungsten or carbon elements, or quartz-halogen lamps.

20 . A toaster according to claim 17 , wherein the first heater comprises first and second radiant heaters arranged in opposite sides of the toasting chamber so as to heat the opposing major surfaces of the at least one food item.

21 . A toaster according to claim 20 , wherein the first and second radiant heaters are substantially identical.

22 . A toaster according to claim 20 , wherein the first and second radiant heaters are arranged to be substantially equidistant from the toasting location.

23 . A toaster according to claim 20 , wherein the first and second radiant heaters comprise different forms of infra-red heater.

24 . A toaster according to claim 20 , further comprising a common control for controlling the heat output from the first and second radiant heaters.

25 . A toaster according to claim 20 , further comprising individual controls for respectively controlling the heat output from the first and second radiant heaters.

26 . A toaster according to claim 17 , wherein the second heater comprises a microwave generator configured to rapidly heat an inner portion and an outer portion of the at least one food item.

27 . A toaster according to claim 17 , further comprising a support for supporting the at least one food item in a predetermined position for heating.

28 . A toaster according to claim 27 , wherein the support comprises a metallic grid, grill, or mesh.

29 . A toaster according to claim 27 , wherein the support comprises a mobile support adapted to move a finished at least one food item from the heating position to a presentation position for removal from the toaster.

30 . A toaster according to claim 29 , wherein the mobile support is automatically operated by electrical interconnection with heating circuitry of the toaster and in response to termination of a heating process.

31 . A toaster according to claim 29 , wherein the mobile support is adapted to operate by way of mechanical linkage to a lid or cover for the toasting chamber which is opened to remove the at least one food item.
