  • Patent number: 7189945
    Abstract: A toaster for heating foodstuffs includes a chassis having a cavity therein and having at least one chassis opening for accessing the cavity. A door is movable with respect to the chassis between a closed position in which the door substantially covers the chassis opening, and an open position in which the cavity is accessible through the chassis opening. A carriage with at least one slot is movable between a first position disposed completely within the cavity and a second position extending at least partially from the cavity through the chassis opening. The toaster has a heating configuration in which the carriage is in the first position and the door is in the closed position to confine the foodstuff being heated and create a generally enclosed chamber within the cavity in which heat and moisture loss is controlled.

  • Patent number: 6667465
    Abstract: A toaster having an electronic circuit including a chip-on-board ASIC that controls the operation of toaster heating elements and an electromagnet to which relatively high voltage is applied to hold an armature carried by a bread carriage and toaster-operating assembly. The armature is freely suspended from a bread carriage and toaster-operating assembly and accurately guided onto the electromagnet when the bread carriage is lowered. The toaster has a one-piece main frame that includes both a base frame plate and a rear frame plate. Several economies are obtained by virtue the construction of the toaster. A one-piece control support member is mounted on the base frame plate that supports both mechanical and electronic assemblies for controlling the operation of the toaster in predetermined relative positions.
