The grid mesh 1034 has a plurality of inner gas outlet holes 1035 arranged in strips, and the inner gas outlet holes 1035 are arranged vertically to the outer gas outlet holes 1031. The outer periphery of the grid mesh 1034 is fixed on the inner wall of the gas outlet area 103, and the grid mesh 1034 is arranged to protrude toward the inner cavity 104.

[0051] Secondly, the two gas pipes 400 are respectively arranged on the periphery of the baking tray 200. By arranging the fire isolation plate 500, the combustion flame ejected from the gas hole 401 is prevented from directly burning the periphery of the pizza dough, and the heating is more uniform. The gas hole 401 and the inclined plate 501 are arranged upwardly in the same direction, which can guide the combustion flame to be ejected upwardly, and the inner cavity 104 can be quickly heated to form hot air.

[0055] In this embodiment, the lower part of the fire isolation plate 500 has a longitudinal plate 502, the inclined plate 501 is connected to the top of the longitudinal plate 502, and the bottom of the longitudinal plate 502 has a bottom hollow area 503 arranged in a horizontal strip shape. The bottom hollow area 503 extends along the length direction of the gas pipe 400, and the combustion area is connected with the rotation area through the bottom hollow area 503.

[0056] The combustion flame and heat ejected from the gas hole 401 are guided by the inclined plate 501 and flow toward the upper part of the rotating area for heating. By arranging the bottom hollow area 503, the heat emitted outward by the gas pipe 400 can also be emitted toward the rotating area through the bottom hollow area 503, thereby achieving simultaneous heat emission above and below the rotating area to achieve a full-range heating effect.

[0057] In this embodiment, the rotating area is recessed downward to form a rotating groove 1021, and the rotating disk 600 is located in the rotating groove 1021; the baking tray 200 is supported by the rotating disk 600 and suspended above the rotating groove 1021, and an annular gap 201 arranged in an annular manner is provided between the outer periphery of the baking tray 200 and the outer periphery of the rotating groove 1021, and the hot air in the inner cavity 104 enters the rotating groove 1021 through the annular gap 201.

[0058] By arranging the rotating groove 1021, the arrangement of the rotating disk 600 is facilitated, and with the support of the rotating disk 600, the baking tray 200 is in a suspended state, and the hot air in the inner cavity 104 can enter the rotating groove 1021 through the annular spacer 201 to heat the bottom of the baking tray 200, so that the entire baking tray 200 is heated evenly, and the bottom of the pizza dough can be heated synchronously, so that the pizza dough is heated evenly.

[0059] In this embodiment, the rotating disk 600 includes a rotating portion 601, and the outer periphery of the rotating portion 601 has a plurality of support arms 602, and the plurality of support arms 602 are arranged around the outer periphery of the rotating portion 601 at intervals, and the inner ends of the support arms 602 are butted against the outer periphery of the rotating portion 601, and the outer ends of the support arms 602 are arranged to extend outward away from the rotating portion 601;

[0060] Along the direction from the inside to the outside of the support arm 602, the support arm 602 is arranged upward away from the bottom of the rotating groove 1021, and the outer end of the support arm 602 extends to the top of the rotating groove 1021; the baking tray 200 is placed on multiple support arms 602, and the bottom of the baking tray 200 is arranged at an interval with the rotating part 601.

[0061] The baking tray 200 is supported by multiple tilted support arms 602 without covering the bottom of the baking tray 200 , thereby satisfying the effect of hot air heating the bottom of the baking tray 200 , so as to achieve the effect of uniformly heating the pizza dough on the baking tray 200 .

[0062] In this embodiment, the middle portion of the support plate has a plurality of middle hollow areas 604 that are arranged vertically through the middle portion, and the outer end of the support arm 602 has a limiting plate 603 that abuts against the outer periphery of the baking tray 200 .

[0063] By arranging the limiting plate 603, the pizza dough is prevented from moving outward from the baking tray 200 during the rotation of the baking tray 200, and by arranging the middle hollow area 604, the bottom of the baking tray 200 is exposed through the bottom hollow area 503, so that more exposed area can be realized at the bottom of the baking tray 200, and the baking tray 200 can be evenly heated.

[0064] In this embodiment, a plurality of protrusions 1022 are provided on the outer periphery of the rotating groove 1021, and the plurality of protrusions 1022 are arranged around the circumferential interval of the rotating groove 1021; two oppositely arranged enclosing plates 300 are provided on the outer periphery of the rotating groove 1021, and the bottom of the enclosing plates 300 abuts against the protrusions 1022, and a horizontal interval is provided between the bottom of the enclosing plates 300 and the bottom of the inner cavity 104, and the horizontal interval is aligned and communicated with the annular interval 201;

[0065] The ends of the two enclosing plates 300 are spaced apart to form a longitudinal spacer 301 arranged longitudinally. The longitudinal spacer 301 is connected to the horizontal spacer and to the annular spacer 201 .

[0066] By arranging two enclosing plates 300, the two enclosing plates 300 are enclosed at the outer periphery of the rotating groove 1021, and the outer periphery of the baking tray 200 is restricted and protected to prevent the baking tray 200 from being separated from the rotating plate 600. In addition, by forming a longitudinal interval 301 and a horizontal interval, it can be connected with the annular interval 201 in multiple ways, so that the hot air in the inner cavity 104 can enter the rotating groove 1021, and the hot air flow between the rotating groove 1021 and the inner cavity 104 can be realized.

[0067] In this embodiment, a rotatably arranged air-permeable mesh layer 1033 is provided in the air outlet interval 1032, and the air-permeable mesh layer 1033 is spaced apart from the grid mesh 1034 and the air outlet area 103, and the periphery of the air-permeable mesh layer 1033 is rotatably connected to the grid mesh 1034;

[0068] When the hot air in the inner cavity 104 passes through the air outlet space 1032 , the hot air flows in the air outlet space 1032 , driving the air permeable mesh layer 1033 to rotate.

[0069] By arranging the breathable mesh layer 1033 in the air outlet gap 1032, the hot air passing through the air outlet gap 1032 can be further blocked from backwashing, thereby reducing the temperature flow change of the hot air in the inner cavity 104. Secondly, the breathable mesh layer 1033 has a certain rotation under the impact of the hot air, which can guide the flow of the hot air and ensure the flow of the hot air in the inner cavity 104.

[0070] In this embodiment, the baking tray 200 is flat, and the interior of the baking tray 200 has a horizontally arranged flat cavity 202, the flat cavity 202 is extended along the plane direction of the baking tray 200, and the periphery of the baking tray 200 is closed; the lower part of the baking tray 200 is provided with a plurality of lower air holes 203 that pass through the upper and lower parts, and the lower air holes 203 are arranged in strips, and the plurality of lower air holes 203 are arranged around the center of the baking tray 200 at intervals and in a radial shape.

[0071] The top of the baking tray 200 has a top surface, and the upper part of the baking tray 200 is provided with a plurality of upper air holes 204 that penetrate up and down, and the plurality of upper air holes 204 penetrate the top surface and are distributed throughout the top surface, and the flat cavity 202 is connected with the inner cavity 104 through the upper air holes 204 and the lower air holes 203 respectively; a plurality of dam rings 205 are provided on the top surface, and the dam rings 205 surround the outer periphery of the upper air holes 204, and a plurality of ventilation notches 206 are provided in the dam rings 205, and the plurality of ventilation notches 206 surround the circumference of the dam ring 205 at intervals.

[0072] When the pizza dough is placed on the baking tray 200, the pizza dough is supported by multiple dam rings 205 and is suspended on the top surface, with a supporting gap between the top surface and the pizza dough. A fan structure is provided in the flat cavity 202, and the fan structure includes a longitudinal axis 208 arranged longitudinally, and the longitudinal axis 208 is eccentrically arranged with respect to the center of the baking tray 200. A horizontally arranged rotating block 209 is connected to the longitudinal axis 208, and a plurality of blades 207 extend outward from the outer periphery of the rotating block 209, and the plurality of blades 207 are arranged around the rotating block 209 at circumferential intervals.

[0073] As the baking tray 200 rotates with the rotating disk 600, the hot air in the inner cavity 104 enters the flat cavity 202 through the lower air hole 203 and is then discharged upward through the upper air hole 204. The hot air discharged from the upper air hole 204 passes through multiple ventilation gaps 206 and enters the supporting gap. The rotating block 209 rotates synchronously in the flat cavity 202.

[0074] Firstly, by providing the flat cavity 202 in the baking tray 200, the thickness of the baking tray 200 can be reduced, which facilitates heating of the baking tray 200 and temperature transfer of the baking tray 200; secondly, the pizza dough is supported in a suspended state by the dam ring 205, and will not bend and abut against the top surface, so that a support gap is formed between the pizza dough and the top surface, so that the bottom of the pizza dough is evenly heated;

[0075] Furthermore, by arranging the lower air hole 203, the flat cavity 202, the upper air hole 204 and the ventilation gap 206, the hot air entering the rotating groove 1021 can flow from bottom to top and enter into the supporting gap, thereby ensuring uniform heating of the pizza dough; in addition, since the longitudinal axis 208 and the baking tray 200 are eccentrically arranged, when the baking tray 200 is rotating and the blades 207 are impacted by the flow of hot air, the rotating block 209 drives the multiple blades 207 to rotate automatically, which can further drive the flow of hot air to achieve more uniform heating and baking of the pizza dough.

[0076] In this embodiment, two fan structures are provided in the flat cavity 202, and the two fan structures are arranged on both sides of the flat cavity 202, and the blades 207 of the two fan structures are arranged in an up-down staggered manner. In this way, when the hot air flows from bottom to top in the flat cavity 202, the blades 207 of the two fan structures are driven to rotate, and the hot air flow is driven up and down in the flat cavity 202 to accelerate the flow of the hot air. Conversely, the accelerated flow of the hot air further drives the rotation of the blades 207.

[0077] The outer circumference of the baking tray 200 is provided with a plurality of spiral holes 800 which are arranged through the baking tray 200. The plurality of spiral holes 800 are arranged around the circumference of the baking tray 200 at intervals. The plurality of spiral holes 800 are arranged tilted in the same direction. From the inside to the outside of the spiral holes 800, the spiral holes 800 are arranged tilted upward. When the baking tray 200 rotates, part of the hot air in the flat cavity 202 spirals out through the plurality of spiral holes 800 and flows upward.

[0078] During the rotation of the baking tray 200, due to the effect of centrifugal force, part of the hot air in the inner cavity 104 flows out through the spiral holes 800 toward the periphery of the baking tray 200 and flows upward. The hot air can flow from bottom to top in the guide baking tray 200, so that the entire inner cavity 104 is heated evenly, thereby achieving uniform heating and baking of the pizza dough.

[0079] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
