ABSTRACT:
FIELD AND BACKGROUND OF THE INVENTION
The present invention relates to food heating appliances. The invention is particularly useful as a bread toaster, and is therefore described below with respect to such an application.
OBJECTS AND BRIEF SUMMARY OF THE INVENTION
An object of the present invention is to provide a food heating appliance capable of heating a food article efficiently and in a relatively short period of time. Another object of the invention is to provide a food heating appliance particularly useful as a bread toaster capable of toasting bread in a relatively short period of time.
According to one aspect of the present invention, there is provided a food heating appliance, comprising: a food compartment for receiving a food article to be heated; at least one heating element located laterally of the food compartment for heating a food article therein; and a heat-transfer plate located between the food article compartment and the heating element; the heat-transfer plate being blackened to absorb heat from the heating element, and being of a corrugated construction having projecting surfaces to contact the food article when received in the compartment for transferring heat to the food article by conduction, alternating with recessed surfaces spaced from the food article and formed with openings for transferring heat to the food article by radiation and convection.
The food heating appliance is particularly useful as a bread toaster, in which case there would be two heating elements and two heat-transfer plates located on the opposite sides of the food article compartment. In addition, the food article compartment is oriented vertically to receive a slice of bread to be toasted.
According to another aspect of the present invention, therefore, there is provided a bread toaster, comprising a pop-up stand movable to an upper loading-unloading position and to a lower toasting position in a bread compartment for receiving a slice of bread to be toasted; a pair of heating elements located on opposite sides of the bread compartment for toasting a slice of bread on the pop-up stand; and a pair of heat-transfer plates on opposite sides of the bread compartment between the heating element thereat and the slice of bread to be toasted; the heat-transfer plates being brought into contact with the slice of bread on the pop-up stand when the pop-up stand is in its lower position, and being moved out of contact with the slice of bread when the pop-up stand is in its upper position.
Further features and advantages of the invention will be apparent from the description below.
