In one embodiment, said electronic interface additional allows users to place the conveyor belt in “static mode,” wherein the conveyor belt does not move or rotate and the food is cooked in a static position.
In one embodiment, the heating means is an infrared lamp. In one embodiment, the heating means is primarily made of tungsten metal. In one embodiment, the heating means is primarily made of nichrome. In one embodiment, the heating means is a halogen heating source. In one embodiment, the heating means is a combination of multiple heating elements; which may consist of one halogen heating source, two infrared lamps on the top of, and two infrared lamps on the bottom of the toaster oven interior region.
In one embodiment, the toaster oven has a transparent viewing panel for viewing food products as they proceed through the toaster oven on said conveyor belt to allow users to view the food stuffs being conveyed through the toaster while maintaining the heat in the oven cavity.
In one embodiment, the conveyor belt frame fits into the inner body of the toaster oven and is insertable and removable into and from the toaster oven providing for easy installation, removal, and replacement of said conveyor belt from within said toaster oven. In some embodiments, the conveyor belt is constructed within a conveyor cartridge to facilitate the ability of a user to insert and remove the conveyor belt and easily install, remove, or replace the conveyor belt from within the toaster oven housing.
In one embodiment, the conveyor cartridge utilizes a clutch mechanism to allow for the ejection or installation of the conveyor belt from or into the toaster oven. In this embodiment, the rotatable shafts are composed of two shaft components: the drive shaft and the guide shaft. The clutch mechanism utilized in this embodiment is a novel spring loaded clutch system in which a female clutch, located on one end of a rotatable shaft, is forced to come into contact with a male clutch, located on the drive motor, by a spring which is compressed between the drive shaft and guide shaft end of the rotatable shaft. This clutch mechanism allows a user to disengage the conveyor belt from the toaster oven by gripping and sliding a drive sprocket frontward, overcoming the force exerted by the spring inside the rotatable shaft, thereby releasing the female clutch from the male clutch. When the clutches are disengaged, the user is able to pull out the conveyor cartridge.
To install the conveyor belt into the toaster, a user simply pushes the conveyor cartridge inside the oven. Once the conveyor cartridge is pushed inside the oven, a lever approaching the chassis is triggered to push in the female clutch of the conveyor drive so that the conveyor cartridge can be fully inserted.

In one embodiment, the second door is pivotably attached to the conveyor cartridge. In this embodiment, the conveyor cartridge and the second door are both removable from the toaster oven. When the toaster oven is configured in this way, a user is able to pull out the second door and the chain link conveyor belt by pulling the second door. This creates a wider opening and enables a user to easily clean the toaster oven chamber.
In one embodiment, the second door is not attached to the conveyor cartridge, rather, its pivot axis can be detached from the body of the toaster. In this embodiment, the second door is permanently pivotably connected to second door flap which allows the second door to extend outward when its pivot axis is de-tached from the toaster oven housing, all the while remaining pivotably attached to the second door flap. Therefore, in this embodiment, the chamber opening is wider than the opening is when the second door pivot access is attached, and a user can easily reach into the toaster oven body and remove the conveyor belt via the conveyor cartridge from within the toaster oven body. When the second door is detached, and the conveyor belt is removed from within the body of the toaster oven, a user is able to easily clean and maintain the inside of the toaster oven.
