  • Patent number: 6298772
    Abstract: A toaster having a ferromagnetic armature movable between an engaged position adjacent to a solenoid and closing a switch and a disengaged position away from the solenoid and opening the switch. A displacement assembly is adapted to move from an up position through a toasting position to a down position, whereupon the displacement assembly displaces the armature from the disengaged position to the engaged position, closing the switch and energizing a heating element and the solenoid, thus retaining the armature in the engaged position. The armature engages the displacement assembly when the armature is in its engaged position to retain the displacement assembly in the intermediate toasting position. A timer de-energizes the solenoid upon completion of toasting, releasing the armature to return to the disengaged position, thus opening the switch and causing de-energization of the heating element independently of the displacement assembly returning to the up position.

  • Patent number: 6129007
    Abstract: An electric automatic pop-up toaster has a carriage and a pivotably connected manually operative arm for moving the carriage to a lowermost position for toasting in well-known manner. At the beginning of each toasting cycle, the arm is horizontal and a latching plate is magnetically held down to hold the arm and the carriage in a lowermost position. The arm presses against a wire spring to hold closed a power switch (not shown) that supplies power to heating elements of the toaster. The latching plate is (magnetically) released at the end of each toasting cycle by a timer. This allows the carriage to move upwards to pop-up toasted bread in a usual way. However should the carriage fail to move upwards when the latching plate is released, the arm is pivoted by a spring and tilted to the position shown in the Figure. The wire is therefore released and enters a slot in a bracket mounted to the carriage. The switch opens and remains open to prevent power being re-instated to the heating elements.

  • Patent number: 5960704
    Abstract: An improved contact toaster for heating sandwich buns and other food items features a housing containing a toasting chamber with an inlet and an outlet. The toasting chamber contains a pair of conveyor belts with a heated platen positioned between them. Each conveyor belt features a platen-facing portion so that two pathways are defined. Each conveyor belt also features a heat-distributing surface. Two auxiliary heaters are positioned so that one of each heats one of each of the platen-facing portions of the conveyor belts. One of each of a pair of tensioners engages one of each of the platen-facing portions of the conveyor belts so that each pathway tapers inward to a minimum thickness and then expands outward again. As a result, food items moving through the pathways via the conveyor belts are toasted on both surfaces and also absorb heat from both the platen and the conveyor belt surfaces in a sponge-like manner as they are compressed and released.

  • Patent number: 5819637
    Abstract: A Toaster having heating elements whose heating area depends on the slice size. A toaster has heating elements (H1, H2) divided into sub-elements (H1A, H1B; H2A, H2B) which can be activated individually. The size of the product to be toasted (5) is detected by means of a sensor, for example a mechanical sensor (2) or an optical sensor device with a photo-emitter and a photo-receiver. The sub-elements are activated selectively in dependence on the detected size. Thus, the power consumption of the toaster is adapted to the size of the product to be toasted and overheating of the product in the proximity of the unused heating area of the heating elements is avoided.
