摘要:
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. The armature can move upward relative to the bread carriage at the end of a toasting cycle if the bread carriage accidentally becomes stuck so that the power switches will assuredly be opened at the end of toasting cycle. A barrier is provided between live electricity and the toaster cover. A crumb tray is provided that may be mounted on the base frame member without the use of tools or additional parts.

An electric toaster includes a chassis with one or more toasting compartments. At least one electric heater is located in each compartment, and a cage is positioned in each compartment adjacent the heater. The cage includes lateral sides with a gap therebetween for receiving a food item and stationary supports that extend into the gap from the lateral sides for supporting the food item during a toasting operation. The electric toaster also includes a movable food support rod that is positioned in the toasting compartment for movement between an upper rest position and a lower toasting position below the stationary supports. The movable food support rod is adapted to support the food item above the stationary support and to transfer support of the food item to the stationary support when the movable food support rod travels below the stationary supports. A switch is positioned for activation by downward movement of the movable support from the stationary supports toward the lower toasting position to energize the electric heater. The switch is deactivated upon upward movement of the movable support from the lower toasting position toward the stationary supports to deenergize the at least one electric heater before reengagement of the movable support with the food item. In this manner, operation of the toaster can be stopped at the end of a toasting cycle independently of the presence or absence of a food jam.

A switching mechanism is utilized in a heating appliance, such as a toaster, that includes a bread support that supports a food item to insert and remove the food item from a cooking cavity of the appliance. The appliance includes an electronic circuit that controls operation during a heating cycle. The switching mechanism includes a switch having a first terminal adapted to receive a power signal and a second terminal coupled to the electronic circuit. The switch operates responsive to an applied switching force to couple the first terminal to the second terminal and thereby apply power to the electronic circuit. A switch actuator has a first end, a second end, and a retaining member near the second end. The second end is attached to the appliance to rotate about an axis. The switch actuator operates responsive to a force being applied to the bread support to rotate about the axis to a first position and apply the switching force to the switch so power is applied to the electronic circuit. A retaining force is applied to the first end of the actuator to secure the actuator in the first position responsive to power being applied to the electronic circuit and the retaining member engages the bread support to hold the bread support with the food item positioned in the cooking cavity when the actuator is in the first position. The switch actuator operates responsive to the retaining force being removed to rotate about the axis to remove the switching force and thereby remove power from the electronic circuit to terminate the heating cycle. Various other aspects of the present invention are directed, for example, to contacts formed on a printed circuit board and switch blades formed separate from the printed circuit board, heat-staking of the switch blades, and crimp details on the switch blades that eliminates the need for wire terminals.

A heating apparatus having a heating grid array wherein individual elements of the heating grid array may by selected, thereby producing a heating/browning effect from the selected elements. Groups of the individual elements may be selected such that a desired heating/browning pattern is achieved. Elements of the grid array are selected for a duration of time such that a desired heating/browning pattern is produced. The heating apparatus contains an addressing circuit for addressing the grid array and a memory for storing heating/browning patterns. The heating device also contains a timing element for controlling the duration of time that the heating/browning pattern is applied. The memory contains duration data corresponding to all, or portions of the selected elements of the grid array. The duration data varies over the selected elements of the grid array so that different selected elements of the grid array are selected for different durations of time.

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.
