Abstract:
A heater having an insulating terminal mounting block, a thermostat and a terminal bushing mounted to a frame. The insulating terminal mounting block supports a plurality of removable terminal members. Each terminal member has a crimping structure at one end and a connection structure at its other end. A temperature sensitive fuse is crimped within the crimping structure of a first and a second of the terminal connection members. A unitary jumper strap connects between the connection structure of the second and a third of the terminal members. A fourth terminal member is supported by the terminal bushing. A second unitary jumper strap connects between the connection structure of the fourth terminal member and a terminal of the thermostat. One terminal of a resistive heating wire is crimped within the crimping structure of one of the terminal connection members supported by the terminal mounting block. Another terminal of the resistive heating wire is crimped within the crimping structure of the fourth terminal connection member.
Abstract:
A clip (1) for connecting one or two insulators (20) to a rail (60) (preferably a T-bar member) of an electric heater (70) including a main body (2), a means (4) for securing an insulator to the main body, and at least one bendable metal clinching member (3) extending from the main body, where the clip is securable to the rail by bending the clinching member around the rail. Preferably, the clinching member is one or two T-shaped end members disposed on transverse ends of the main body. Opposite end sections of the ridge (3a) of the T-shaped end members constitute clinching flaps (5) which, in use, are clinched around a stem (3b) of a T-bar of an electric heater. The clip is not welded to the T-bar.
Abstract:
Provided is a heating unit for an oven that does not employ conventional heat rays, lamps, and high frequency to cook food, but instead uses a ceramic heater and a heating element coated with ceramic to cook food, so that far-infrared radiation and anions are emitted during cooking to increase the taste of cooked food and allow food to be properly cooked without being burnt, thereby increasing the overall effectiveness of the oven. The heating unit includes a heating element, a controller, and a heat blocking plate. The heating element includes a ceramic heater that emits heat using supplied electrical power, and a heat radiating plate that radiates the heat emitted by the ceramic heater toward food. The heat blocking plate blocks the heat emitted by the ceramic heater from being conducted outside the oven. The controller blocks the electrical power supplied to the ceramic heater and sounds an alarm or illuminates a warning light, according to a control command issued by a microprocessor, when a temperature of the heat radiated by the heat radiating plate exceeds a preset temperature.

A heater having a frame rail (50) and clips (40), attached to the rail, for securing insulators (60) for supporting a heater coil. Each clip has a main body having a structural member for securing to the rail, and having a pair of flanges (8.10) symmetrical about the central axis. Each flange has a cut-out (16) for supporting an insulator, the cut-out having an open end, a back abutment edge and a pair of side abutment edges. A bendable tab (20, 22, 24) is located at either side of the open end, each having a first and a second position. In the first position an insulator is insertable into the cut-out, and the insulator is secured by bending the tabs to their second position. Optionally the main body has a cross-section that accommodates the cross section of the rail (90) and the rail is welded to the channel (2). Alternatively, a plurality of clinching flaps (42, 44) extend from the main body, the flaps shaped and dimensioned for bending around and clinching the rail.
