[0001] This utility model relates to the field of barbecue equipment technology, specifically a box-type smokeless barbecue grill. Background Technology

[0002] Barbecue, as a cooking method, is becoming increasingly popular, especially among people who enjoy outdoor cooking. As a result, various barbecue grills have appeared on the market. Most barbecue grills currently use charcoal grilling. People place charcoal in the grill and then place the skewers on the rack and manually turn them over to grill. However, during the grilling process, the hot air generated by the burning charcoal passes through the fresh meat and continues to flow upwards. The heat in the hot air is not fully utilized, resulting in a waste of resources and low energy efficiency. Utility Model Content

[0003] In order to solve the technical problems existing in the prior art, the present invention provides a box-type smokeless barbecue grill.

[0004] To achieve the above objectives, the present invention proposes the following technical solution: a box-type smokeless barbecue grill, comprising a grill body with open sides, grill doors symmetrically hinged on both sides of the grill body, and multiple slanted placement slots evenly distributed from top to bottom at the edges of the two grill doors, each slanted placement slot gradually sloping downward from the opening end to the closing end.

[0005] A partition is fixed vertically in the middle of the interior of the furnace door. The bottom of the partition is a certain distance away from the bottom of the furnace body, and the top of the partition is bent towards the opening of the furnace door and then connected to the edge of the opening of the furnace door.

[0006] The front end of the furnace body is equipped with an air intake grille, and multiple smoke exhaust ports are opened at the top of the furnace door.

[0007] Preferably, a sealing baffle is integrally formed and connected to the edges on both sides of the front end of the furnace body, and the width of the sealing baffle is smaller than the beveled placement groove.

[0008] Preferably, each sealing edge has at least one notch, and a spring is connected to the notch.

[0009] Preferably, a limiting groove is provided on the inner wall of the furnace body at the position corresponding to the air inlet grille. An adjusting plate is slidably installed in the inner wall of the limiting groove in the horizontal direction. A through groove adapted to the shape of the air inlet grille is provided on the surface of the adjusting plate. A connecting rod in the middle of the adjusting plate passes through the outside of the furnace body and is connected to an operating rod. A groove is provided on the wall of the furnace body for the operating rod to slide.

[0010] Preferably, a baking tray is installed on the top of the oven body.

[0011] Preferably, the baking tray is detachably connected to the oven body via a snap-fit ​​mechanism.

[0012] Preferably, the length of the baking tray is the same as the sum of the lengths of the oven body and the two oven doors, and the bottom of the baking tray is inclined towards the exhaust vents of the two oven doors.

[0013] Preferably, two clamping plates are fixed on the inner side of the furnace body near the bottom. Each clamping plate has a U-shaped structure to support and place the charcoal box. The position of the charcoal box corresponds to the air inlet grille. The charcoal box has a hollow structure, and an ash collection box is placed below the charcoal box.

[0014] This application proposes a box-type smokeless barbecue grill, which has the following advantages compared with the prior art:

[0015] (1) This application divides the oven door into two spaces by installing a partition inside the oven door. The hot airflow generated by the burning charcoal first fills the first space, and then enters the second space downwards along the partition due to the closed top, thus achieving double-sided roasting of fresh meat. This method can make full use of the heat of charcoal, speed up the grilling process, save charcoal, improve the energy efficiency of the grill, and make the entire grilling process more efficient and energy-saving.

[0016] (2) A sealing edge with a width smaller than the inclined placement groove is set on both sides of the front end of the furnace body. When the furnace door is closed, the sealing edge can block most of the inclined placement groove. The sealing edge is also provided with a notch for connecting springs, which can make the furnace door tightly closed and prevent it from springing back. This effectively improves the sealing performance of the barbecue oven, reduces heat loss, ensures the relative sealing of the barbecue space, and thus improves the barbecue effect.

[0017] (3) A limiting groove and an adjusting plate are installed on the inner wall of the furnace corresponding to the position of the air inlet grille. The adjusting plate has a through groove that matches the shape of the air inlet grille. The adjusting plate can be driven to slide horizontally by the operating rod to adjust the size of the air inlet grille opening. This design can flexibly control the amount of air entering the furnace according to the actual grilling needs, thereby adjusting the intensity of charcoal combustion and the size of the hot airflow to meet the grilling requirements of different ingredients.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 This embodiment proposes a box-type smokeless barbecue grill, including a grill body 1 with openings on both sides. Grill doors 2 are symmetrically hinged to both sides of the grill body 1. Multiple slanted placement slots 5 (approximately 10 sets) are evenly distributed from top to bottom along the edges of the two grill doors 2. Each slanted placement slot 5 gradually slopes downwards from its opening end to its closing end, allowing barbecue skewers to be fixed within the slot. The slanted placement slots 5 located at the front of the grill body 1 penetrate the outer wall of the grill door 2, while those located at the rear of the grill body 1 do not penetrate the grill door 2 (for sealing purposes), meaning the tips of the barbecue skewers rest on the rear slanted placement slots 5. Two retaining plates 10 (each retaining plate 10 has a U-shaped structure) are fixed near the bottom of the inner side of the grill body 1 to support and hold a charcoal box 9. The entire charcoal box 9 has a hollow structure, containing charcoal. The ash produced by burning the charcoal falls into the ash collection box 8 below.

[0027] When barbecuing, the staff opens the oven door 2 and inserts the skewered barbecue pieces into the slanted placement slot 5 in turn. Then, the two oven doors 2 are closed, and a relatively sealed barbecue space is formed inside the oven body 1 and the two oven doors 2. The hot air generated by the burning charcoal diffuses into the barbecue space, thereby grilling the fresh meat on the barbecue skewers. In traditional grilling methods, the hot airflow generated by charcoal passes over the fresh meat and is directly discharged from the oven body 1. However, this hot airflow is not fully utilized, resulting in resource waste. To fully utilize the heat of the charcoal, this embodiment has a partition 13 fixed vertically in the middle of the interior of each oven door 2. The partition 13 divides the oven door 2 into two spaces (the side facing the opening of the oven door 2 is the first space, and the side facing away from the opening of the oven door 2 is the second space). A certain distance is reserved between the bottom of the partition 1 and the bottom, facing the opening of the oven door 2, bends and seals with the edge of the opening. The hot airflow generated by the charcoal moves upward and fills the first space. However, because the top of the first space is sealed, the hot airflow moves downward along the partition 13 into the second space. The downward-moving airflow grills both sides of the fresh meat, while the partition 13 also stores and absorbs heat to grill the meat. This method grills quickly, saves charcoal, and makes the entire grill highly efficient and energy-saving. The hot airflow is finally discharged through multiple exhaust vents 4 at the top of the oven door 2 (the exhaust vents 4 are connected to the second space).

[0028] It should be noted that, in order to facilitate the cleaning of the charcoal inside the ash box 8 and the charcoal box 9, the charcoal box 9 is placed directly on the card plate 10, while the ash box 8 is placed below the charcoal box 9. As for the size of the two, the length of the ash box 8 is only slightly larger than that of the charcoal box 9.

[0029] Since the opening edge of the oven door 2 has a through-cut slanted placement groove 5, and considering its sealing properties during grilling, this embodiment uses integrally formed sealing baffles 11 on both sides of the front end of the oven body 1. Note that the width of the sealing baffles 11 is slightly smaller than the slanted placement groove 5. This way, when the oven door 2 is closed, the sealing baffles 11 can largely seal the slanted placement groove 5 without interfering with the grill skewers. In addition, the sealing baffles 11 have at least one notch, and the notch is connected to... Figure 6 The spring 12 shown can make the furnace door 2 tightly closed and prevent it from springing back, thus providing good sealing performance.

[0030] An air intake grille 6 is provided at the front end of the furnace body 1, corresponding to the charcoal box 9. Outside air enters the furnace body 1 through the air intake grille 6 and blows onto the charcoal box 9, providing sufficient oxygen to the charcoal. The air also pushes the hot airflow generated by the charcoal upward to fill the first space, and then downward to enter the second space, thereby achieving double-sided roasting of the fresh meat. In order to adjust the airflow size of the air intake grille 6, this embodiment also provides a limiting groove 16 on the inner wall of the furnace body 1 at the position corresponding to the air intake grille 6. An adjusting plate 15 is slidably installed in the horizontal direction inside the limiting groove 16. A through groove 17 adapted to the shape of the air intake grille 6 is opened on the surface of the adjusting plate 15. The connecting rod in the middle of the adjusting plate 15 passes through the outside of the furnace body 1 and is connected to an operating rod. A groove is opened on the wall of the furnace body 1 for the operating rod to slide. The operator can drive the adjusting plate 15 to slide horizontally through the operating rod, thereby adjusting the opening size of the air intake grille 6.

[0031] It is conceivable that, to facilitate operation of the oven doors 2 and prevent burns, each oven door 2 is equipped with a high-temperature resistant handle. Additionally, this embodiment also features a baking tray 3 mounted on top of the oven body 1. The baking tray 3 serves two purposes: firstly, it can be used for seasoning; secondly, its length is exactly the same as the sum of the lengths of the oven body 1 and the two oven doors 2. Furthermore, the bottom of the baking tray 3 is angled towards the exhaust vents 4 of the two oven doors 2. This design ensures that heat is not obstructed and that the baking tray 3 absorbs heat after the hot air blows towards its bottom, thus keeping the grilled skewers warm. The baking tray 3 has a latch 7 at both the front and back for easy removal and cleaning.
