Detailed Description

The technical solution of the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 to 4, the fixing structure of the heating pipe 130 of the electric baking pan includes a cavity surrounded by the lower casing 100 and having an open upper side, and a fixing plate 150 disposed in the cavity, wherein the heating pipe 130 is disposed above the fixing plate 150 in a bent shape; still include a plurality of fasteners 140, be equipped with the fluting on the fixed plate 150, the middle part of fastener 140 is buckled into downwardly opening's holding chamber 141, heating pipe 130 imbeds in the holding chamber 141, one side of holding chamber 141 extends there is fixed part 142, the opposite side of holding chamber 141 extends there is joint portion 143, joint portion 143 passes the fluting inserts the fixed plate 150 the below and with the fixed plate 150 joint.

The shell further comprises a tray part 500, wherein the tray part 500 is arranged above the lower shell 100, and the bottom of the tray part 500 is abutted against the top of the accommodating cavity 141 of the fastener 140. The bottom of the tray portion 500 may directly transfer heat from the fastener 140, which may be beneficial to improve heat utilization.

The fixing plate 150 is plate-shaped, a plurality of convex surfaces 151 protruding upwards are arranged on the upper surface of the fixing plate 150, the groove is located on the convex surfaces 151, and the fixing plate 150 is fixed with the convex surfaces 151. The plate-shaped fixing plate 150 can be subdivided into a plurality of cavities separated from each other in the cavity, so as to facilitate the arrangement of various parts; meanwhile, since the slots are formed on the convex surface 151, the fixing plate 150 and the convex surface 151 are fixed to make the heating tube 130 contact with each other in a smaller area, thereby reducing heat conduction to the lower side of the heating tube 130.

A gap is left between the fixing plate 150 and the bottom of the lower case 100; the bottom of the lower shell 100 is provided with a receiving space formed by inward depression, and a receiving box 300 which is connected in a relatively sliding manner and is opened at the upper part is arranged in the receiving space; an opening 103 is formed in the lower case 100 surrounding the storage space, and the storage case 300 is communicated with the gap through the opening 103.
