A HEATING STRUCTURE FOR A HEATING CABINET

摘要

A heating structure of an electric heating cabinet is provided to prevent deformation of or damage to both side wall surfaces or a heater case due to exposure to a high temperature. In an electric heating cabinet, heaters(20) are installed at lower end portions of both side wall surfaces of the interior of the heating cabinet body. An insulation material(23) is installed at an upper end portion of the interior of a heater case(22) in which a heat transferring body of the heater is embedded. A plurality of ventilation holes(24) are formed on the front and lower end surfaces of the heater case to prevent the air of high temperature from directly making contact with both side wall surfaces of the interior of the heating cabinet. The air heated by the heat transferring body of the heater rises in the interior of the heater case but the upper end of the heater case is closed by an insulation body. The heated air is discharged through the plurality of ventilation holes.
