Description

Technical Field

[0002] At present, people generally use ordinary metal columnar square tubes to make the frame of the oven body. This columnar square tube frame has the advantages of simple structure, convenient production, good rigidity, high strength, beautiful appearance and low cost. However, it has the fatal disadvantages of large heat transfer coefficient and poor insulation effect. It cannot be used in general oven bodies, which greatly limits its use.

[0003] Application No. 200420046484.5 discloses a heat-insulating square column for a baking oven, which comprises two or more long vertical column pieces, which are fixedly connected by connecting pieces, and a gap is left between the column pieces. The heat-insulating square column is composed of two column pieces, and the cross-section of the column piece is L-shaped or U-shaped. The connecting piece between the column pieces is block-shaped and transversely fixed in the square column, and a long vertical column piece with an L-shaped or U-shaped cross-section is used, and a gap of a certain width is left between the column pieces. The two column pieces are welded together by a metal sheet with the same shape as the transverse cross-section of the cavity or a metal connecting sheet placed in the gap.

[0004] The heat in the oven can only be transferred through the metal connecting pieces between the insulating square column sheets, which greatly reduces the heat transfer coefficient. However, as the oven continues to operate, the heat transferred by the metal connecting pieces will continue to increase, and a large amount of heat will be transferred after a long time.

[0030] There are four conductive sheets 106, and the drain pipe 103 is located at the bottom of the conductive sheet 106.
