Household electronic toaster and method of manufacture

This invention relates to a household electronic toaster and a method of manufacturing the same, but aspects of this invention can be used in other heating appliances, particularly toasters for commercial use. 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.
