DETAILED DESCRIPTION

The present application will be described in further detail below with reference to FIGS. 1-8.

An integrated oven with functions of frying, roasting and smoking according to an embodiment of the present application, as shown in FIG. 1, includes a lower oven body 1 and an upper oven body 2.

The lower oven body 1 includes a lower oven base 11. Two support feet 112 are arranged on one edge of a lower end face of the lower oven base 11. Two trolley wheels 113 are rotatable connected to the lower oven base 11 on one edge of the lower end surface away from the support feet 112. When it is necessary to move, the integrated oven may be pried up by taking the trolley wheels 113 as support points, so that the support feet 112 are separated from the ground, and at this time, the integrated oven is driven to move by the trolley wheels 113.

A roasting cavity 111 is provided at a front end face of the lower oven base 11. Support blocks 12 are arranged on two inner walls of the roasting cavity 111 opposite to each other in a horizontal direction. The support blocks 12 are arranged in four layers on each of the two inner walls in a vertical direction, and heights of each layer of the support blocks 12 on one of the two side walls is in one-by-one correspondence to that on the other one of the two side walls.

Referring to FIGS. 1 and 2, three layers of load grids 13 are arranged in the roasting cavity 111. The load grid 13 is a metal mesh, and the three layers of load grids 13 are arranged at intervals in the vertical direction. The three layers of load grids 13 in the roasting cavity 111 are respectively arranged on upper three layers of the support blocks 12. The load grids 13 are arranged on corresponding support block 12, and two ends of each of the load grids 13 are supported by the support blocks 12. Installation of the load grids 13 can be conveniently achieved by placing them on the support blocks 12 according to the actual use.

Referring to FIGS. 1 and 3, a bearing frame 14 is also arranged in the roasting cavity 111 below all load grids 13. Lower end faces of both ends of the bearing frame 14 abuts against upper end faces of support blocks 12 on the lowest layer for supporting and positioning the bearing frame 14. A first accommodating hole 141 and a second accommodating hole 142 are provided on an upper end face of the bearing frame 14. In actual production, the bearing frame 14 is formed by splicing metal rods.

A smoking box 15 is arranged in the first accommodating hole 141. The smoking box 15 includes a box body 151 and a box cover 152. A cavity is formed on the upper end face of the box body 151 for storing smoking materials.
