[0022] like Figure 1~Figure 4 As shown, the utility model provides a hot air furnace, comprising a box body 1, in which a tray grid assembly 2 is installed, the tray grid assembly 2 is used to isolate the baked product from a heating assembly, and the heating assembly is installed in the box body 1.

[0023] The heating assembly comprises a fan 5, and a heating pipe 7 is wound around the fan 5. The inner wall of the top of the box body 1 is an arc-shaped top 4.

[0024] Therefore, when the fan 5 and the heating tube 7 are turned on, the heating tube 7 generates heat, and the fan 5 rotates to blow out the hot air. Due to the physical principle that hot air moves upward, when the hot air above meets the arc-shaped top 4, it moves to both sides under the push of the hot air below, thus forming a three-dimensional surrounding hot air, so that the heat received by the baked food is uniform, and the heat energy is evenly distributed in the box 1.

[0025] Furthermore, the heating assembly also includes heat storage blocks 6 located outside the two sides and at the bottom of the fan 5. A water inlet pipe 8 is provided above the heat storage block 6. When the heating tube 7 in the inner box is working, a large amount of heat energy will be generated. This heat energy is transferred to the heat storage block 6 through the air. Each small iron sheet maintains a high temperature. When the water inlet pipe 8 starts to flow in, water drops fall on the heat storage block 6 to instantly generate high-temperature water vapor. This water vapor provides a softening effect on the bread. When the water inlet stops, the heat storage block 6 continues to store heat to prepare for the next water vapor supply.

[0026] When water vapor is generated, the trajectory of the water vapor is the same as that of hot air, thus ensuring that the food is evenly softened by the water vapor around it.

[0027] The inner wall of the box body 1 is composed of a surrounding plate 11, an arc-shaped top 4, a rear plate 10 and a rear reinforcing plate 3; the motor of the fan 5 is installed on the rear plate 10 through a motor fixing plate 9, and a rear reinforcing plate 12 is installed on the rear plate 10, so as to further strengthen the supporting force of the rear plate 10.

[0028] In fact, the enclosure plate 11 is cut out by laser, and then bent into shape by a bending machine. The top plate is cut out by laser, and then pressed into an arc shape by a mold. Then the rear plate 10 and the rear reinforcement plate 3 are cut out by laser, and then these plates are welded together.

[0029] Please focus on Figure 5 The tray grid assembly 2 includes a side net and a rear net. A plurality of tray frame sheets 201 are symmetrically arranged on the side net. At the same time, in order to prevent the heat storage block 6 from directly contacting the product, a tray frame screen 203 is arranged between the rear net and the tray frame sheet 201. The tray frame screen 203 is symmetrically arranged on the side net. In order to facilitate the circulation of hot air and water vapor, a plurality of holes are arranged on the tray frame screen 203, a plurality of side mesh holes 202 are arranged on the side net, and a plurality of rear mesh holes 204 are arranged on the rear net.

[0030] The mesh plate is made by laser cutting or punching, and then bent into shape by a bending machine. The pallet grid screen 203 and the pallet frame sheet 201 are welded to the pallet grid.

[0031] The design of this device can ensure that the hot air circulates evenly in the furnace body, and at the same time can ensure that the surrounding of the food is evenly softened by the water vapor.

[0032] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
