PROBLEM TO BE SOLVED: To provide a storing chamber for efficiently heating warm air in a cabinet and enabling circulation and supplying of it without resistance. SOLUTION: A heating cabinet body 1 has a ventilating duct for circulating and supplying the warm air to the storing chamber 7 in a cabinet. The ventilating duct comprises lateral face ducts 11 and 11 extended along right and left side walls 5 and 5 of the heating cabinet body 1, and a ceiling duct 12 extended along an upper wall 2 of the heating cabinet body 1. The ceiling duct 12 is partitioned from the storing chamber 7 by a hollow box-like partitioning box 16. Suction ports 22 are provided on front and rear ends of the partitioning box 16, and air in the storing chamber is sucked into the partitioning box 16 through the suction ports 22. A communicating opening 25 is provided in the center of an upper plate 17 of the partitioning box 16. A sirocco fan 26 is arranged above the communicating opening 25 of ceiling duct 12 so as to be driven and rotated around a vertical axis, and a sheathed heater 29 is arranged on an outer circumference of the sirocco fan 26. The air in the storing chamber sucked into the partitioning box 16 is collected in the communicating opening 25, flows into the ceiling duct 12, and heated by the sheathed heater 29 so as to generate the warm air. The warm air is blown out from the lateral face ducts 11 and 11 to the storing chamber 7. COPYRIGHT: (C)2006,JPO&NCIPI
