Description

Technical Field

[0001] The utility model relates to the technical field of barbecue ovens, in particular to a cast iron heating structure for barbecue ovens. Background Art

[0002] When using a barbecue grill for barbecue, some people still use smokeless charcoal in conjunction with the barbecue grill for barbecue, because charcoal grilling will have a smoky smell and improve the flavor of food, but charcoal fire requires air supply when burning, and if the charcoal block is large in size, it will cause internal heat transfer to be slower, and the larger charcoal block has a smaller combustion surface area, thereby slowing down the combustion speed, resulting in lower combustion efficiency of the charcoal block. It is necessary to manually break up the larger charcoal blocks, which is more inconvenient, and the charcoal blocks need to be moved when the charcoal fire is burning to make the burned charcoal ash on the charcoal blocks fall off to prevent the charcoal ash from affecting the contact between the charcoal blocks and the air, resulting in lower combustion efficiency of the charcoal fire. Usually, the charcoal blocks are manually moved when barbecue, which is more inconvenient. Utility Model Content

[0026] Embodiment 1

[0027] like Figure 4-5 As shown, in the present embodiment, the interior of the cylinder 310 is connected with the interior of the containing mechanism 400, and a connecting port 311 is provided at the top of the outer wall of the cylinder 310, a motor box 330 is fixedly connected to the inner bottom surface of the box body 100, and a driving motor is arranged inside the motor box 330, one end of the auger shaft 320 is fixedly connected to the motor shaft of the driving motor, a connecting frame 340 is fixedly connected to the other side of the partition 210, and a funnel 341 is fixedly connected to the bottom end of the connecting frame 340, the bottom end of the funnel 341 is fixedly sleeved inside the connecting port 311, and the interior of the funnel 341, the interior of the connecting frame 340 and the interior of the cylinder 310 are all connected.

[0028] In this embodiment, when adding charcoal blocks to the containing mechanism 400, the charcoal blocks are placed in the connecting frame 340, so that the charcoal blocks pass through the funnel 341 and then enter the cylinder 310 through the connecting port 311, which is convenient for users to add charcoal blocks. Then the driving motor is started to drive the auger shaft 320 and the auger plate to rotate synchronously. The auger plate will drive the charcoal blocks through the cylinder 310 into the containing mechanism 400. If the charcoal blocks are large, the auger plate can press the charcoal blocks through itself and the inner wall of the cylinder 310 to crush part of the charcoal blocks, thereby making it convenient for users to add charcoal blocks. The auger plate and the inner wall of the cylinder 310 can also crush oversized charcoal blocks to prevent the charcoal blocks from being too large to burn.

[0029] like Figure 5-6 As shown, in the present embodiment, the containing mechanism 400 includes a top plate 410, and a base frame 420 is arranged below the top plate 410, the top surface of the top plate 410 is fixedly connected to the bottom surface of the connecting box 220, and the bottom end of the base frame 420 is fixedly connected to the bottom surface of the box body 100, a connecting tube 430 is fixedly connected between the top plate 410 and the base frame 420, and circular holes are opened on the top surface of the top plate 410, the bottom surface of the connecting box 220 and the top surface of the base frame 420, the interiors of the three circular holes are all connected to the interior of the connecting tube 430, and a turntable 421 is rotatably sleeved inside the circular holes on the base frame 420, the outer wall of the connecting tube 430 is fixedly connected to the igniter 460, and one end of the cylinder 310 is fixedly connected to the outer wall of the connecting tube 430, and the interior of the cylinder 310 is connected to the interior of the connecting tube 430.

[0030] In this embodiment, the charcoal blocks are transported to the interior of the connecting tube 430 through the auger plate and automatically fall to the top surface of the turntable 421. The user can then start the igniter 460 to ignite the charcoal blocks, and use the burning heat of the charcoal blocks to provide heat for the barbecue net 240 for barbecue.

[0031] like Figure 6As shown, in this embodiment, the inner wall of the connecting tube 430 is fixedly connected to two convex strips 431, and a pressure plate 440 is arranged inside the connecting tube 430, and the outer wall of the pressure plate 440 is provided with two notches 441, and the two convex strips 431 are respectively slidably engaged in the two notches 441, and a plurality of heat dissipation holes 442 are provided on the top surface of the pressure plate 440, and a rotating rod 450 is rotatably connected to the bottom surface of the box body 100, and the top end of the rotating rod 450 passes through the center of the rotating disk 421 and is fixedly connected to the center of the rotating disk 421, and a thread is provided on the outer wall of the rotating rod 450, and a thread is provided on the center of the top surface of the pressure plate 440 The threaded holes are screwed together with the outer wall of the rotating rod 450, and the driving box 401 is fixedly connected to the bottom surface of the connecting box 220, and a power motor is arranged inside the driving box 401. The motor shaft of the power motor and the bottom end of the rotating rod 450 are fixedly sleeved with a gear 451, and a toothed belt 452 is rotatably sleeved between the outer walls of the two gears 451. A counterweight ring 443 is arranged above the pressure plate 440, and a plurality of push rods 444 are fixedly connected to the bottom surface of the counterweight ring 443, and the bottom ends of the plurality of push rods 444 all pass through adjacent heat dissipation holes 442, and the bottom ends of the plurality of push rods 444 all contact with the top surface of the turntable 421.

[0032] In specific implementation, the adjacent gear 451 is driven to rotate by starting the power motor, and the rotating rod 450 is driven to rotate synchronously through the toothed belt 452 and another gear 451, so that the rotating rod 450 can drive the pressing plate 440 to move downward through the thread and the threaded hole on the pressing plate 440, so that the two recesses 441 slide down along the adjacent convex strips 431. At the same time, the rotating rod 450 drives the rotating disk 421 to rotate synchronously, so that the rotating disk 421 drives the supported carbon blocks to rotate synchronously around the center of the rotating disk 421. The user can also insert multiple push rods 444 into the heat dissipation holes 442 on the pressing plate 440 to make As the charcoal blocks rotate with the turntable 421, they come into contact with the fixed rod 444, which makes it easier for the charcoal blocks to change their positions due to the friction with the rod 444 and the rotation of the turntable 421, so that the charcoal blocks can be automatically moved to facilitate their combustion. The pressing plate 440 can move downward to press the charcoal blocks, so that some larger charcoal blocks are crushed to facilitate their combustion. Since the pressing plate 440 is stuck on the two convex strips 431 by the recess 441 and does not rotate, the pressing plate 440 has a certain thickness. Heat can pass through the pressing plate 440 through the heat dissipation holes 442 to prevent the heat from being isolated by the thicker pressing plate 440.

[0033] Embodiment 2

[0034] On the basis of the first embodiment, two exhaust fans 110 are provided to improve the combustion effect of the carbon blocks in the connecting tube 430 .

[0036] During specific implementation, an exhaust fan 110 can hammer outside air into one side of the partition 210, allowing the air to enter the interior of the connecting cylinder 430 through the vent hole 432, thereby facilitating the combustion of the charcoal blocks. There is a gap between the inner wall of the circular through hole and the outer wall of the cylinder 310, so that the air on one side of the partition 210 can be drawn out by another exhaust fan 110 and discharged to the outside of the box 100.

[0037] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
