Technical Field
[0001] This utility model relates to the field of barbecue oven technology, and more particularly to a heating hopper used in a barbecue oven. Background Technology
[0002] A Chinese utility model patent with patent number CN202222556108.1 entitled "Heating Hopper for Barbecue Oven" discloses a heating hopper for barbecue oven, including a hopper body that can be pulled out and extended into the barbecue oven. The hopper body is characterized by comprising an inner hopper body with a combustion chamber and a ventilation baffle. The ventilation baffle is disposed on the outer wall of the inner hopper body, and a ventilation groove with an open bottom and closed top is formed between the inner wall of the ventilation baffle and the outer wall of the inner hopper body. The ventilation groove is connected to the combustion chamber through a vent hole, and a pull-out mechanism is provided on the side of the hopper body. However, the ventilation openings of the heating bucket are all located inside the cover plate. When the entire heating bucket is inserted into the barbecue grill, the cover plate covers the opening of the grill's bucket cavity, sealing off the ventilation channel and failing to ensure a continuous air supply from the heating bucket. In addition, the bottom of the heating bucket is directly exposed. If the charcoal in the heating bucket is small or its volume decreases due to burning or cracking, it is easy to leak out from the bottom of the heating bucket, which is not conducive to the cleaning and maintenance of the barbecue grill's inner cavity. Therefore, the structure of this heating bucket needs further improvement. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a heating hopper for barbecue grills that can continuously supply air to the combustion chamber, has a good heating effect, and is easy to clean, in light of the above-mentioned existing technology.
[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: This heating bucket for a barbecue grill includes a bucket body, and a pull-out mechanism that can extend the bucket body into and out of the barbecue grill is provided on the rear side wall of the bucket body. The feature is that: a partition plate is provided in the inner cavity of the bucket body to divide the inner cavity into a combustion chamber and a ventilation chamber. The ventilation chamber is located below and behind the combustion chamber. The bottom and side of the partition plate are provided with through holes that connect the combustion chamber and the ventilation chamber. An opening of the bucket body that connects the ventilation chamber is provided on the rear side wall of the bucket body.
[0005] As an improvement, the bucket body can preferably be composed of a front plate, a side plate, a rear plate, and a bottom plate. The rear plate is a cover plate with an area larger than the front plate that can cover the opening of the combustion furnace bucket cavity. The opening of the bucket body is set on the cover plate, and the pull-out mechanism is connected to the cover plate.
[0006] In a further improvement, the dividing plate may preferably include a bottom plate, a baffle plate, and a top plate. The front end of the bottom plate is connected to the front plate, the rear end of the bottom plate is connected to the bottom end of the baffle plate, the top end of the baffle plate is connected to the front end of the top plate, and the rear end of the top plate is connected to a cover plate. Through holes are provided on both the bottom plate and the baffle plate, and the top plate seals the top of the ventilation chamber. The ventilation chamber is L-shaped, allowing air to be supplied to the combustion chamber from the bottom and sides, ensuring complete combustion of the charcoal in the combustion chamber.
[0007] In a further improvement, the through holes of the baffle can preferably be arranged linearly and horizontally on the baffle, and all the through holes of the baffle are higher than the top of the opening of the bucket body. Extending the air path allows more air to enter the combustion chamber through the through holes of the baffle, resulting in more complete combustion of the charcoal.
[0008] In a further improvement, the opening of the hopper can preferably be located on the cover plate between the two side plates. This prevents air leakage and better traps ash and dust.
[0009] Further improvements include the option that the through holes in the base plate are evenly distributed and cover the entire base plate. This results in a larger air intake, allowing for more complete combustion of the charcoal.
[0010] In a further improvement, the front end of the base plate can preferably be provided with a plug-in protrusion, and a plug-in groove is provided at a corresponding position on the front plate, with the plug-in protrusion plugging into the corresponding plug-in groove. No welding is required for fixation, facilitating the replacement of the partition plates.
[0011] As an improvement, the top of the opening of the bucket body can preferably be higher than the bottom plate of the partition plate. Increasing the vertical airflow path allows more air to enter the combustion chamber through the through holes in the baffle, resulting in more complete combustion of the charcoal.
[0012] As an improvement, the pull-out mechanism can preferably be a pull-out handle, which is directly screwed onto the rear side wall of the bucket body, and the fixed position of the pull-out handle is higher than the opening of the bucket body.
[0013] As an improvement, the pull handle can preferably be provided with a handle recess that can accommodate fingers, and a handle through hole for easy hanging. This makes it convenient to pull, grip, and hang.
[0014] Compared with the prior art, the advantages of this utility model are as follows: an opening is provided on the rear side wall of the hopper, and the opening is connected to the ventilation chamber, which in turn is connected to the combustion chamber through the through hole of the partition plate. Therefore, during the process of pulling out the heating hopper, the combustion chamber can always take in air through the opening of the hopper, maintaining smooth air intake and achieving continuous air intake of the combustion chamber, which facilitates the continuous combustion of charcoal in the combustion chamber and results in good heating effect of the heating hopper. The charcoal placed in the inner cavity of the hopper is located on the partition plate, and the partition plate is located inside the hopper. Therefore, small charcoal pieces and charcoal pieces that have cracked due to combustion will not fall out of the hopper even if they fall through the through hole at the bottom of the partition plate, but will still be collected on the bottom surface of the hopper. This facilitates the collection and cleaning of charcoal ash and helps with the overall cleaning and maintenance of the barbecue grill. Attached Figure Description
