<p>A steam box heated by solar collecting tubes comprises solar collecting tubes (1, 11, 22) and a steam box (2, 12, 21). The solar collecting tubes (1, 11, 22) are radially arranged, and the opening ends of which are connected with the steam box (2, 12, 21) hermetically. A cylindrical body (5, 15) made of poor thermal-conducting material is provided within the solar collecting tube (1, 11, 22) and matches with the solar collecting tube (1, 11, 22). An interspace (6, 16) is defined between the cylindrical body (5, 15) and the inner wall of the solar collecting tube (1, 12, 22), wherein heated liquid may be stored. When the solar collecting tubes (1, 11, 22) are irradiated by sunlight, the liquid is heated rapidly to generate steam. The steam enters the steam box (2, 12, 21) and heats the food in the steam box (2, 12, 21). When the steam box heated by solar collecting tubes is not in use, the solar collecting tubes (1, 11, 22) can be removed from the steam box (2, 12, 21) for easy carrying.</p> |
