The barbecue oven of the embodiment has the following working principle and using process.

When the barbecue grill is not in use, the resting portion 1, the side wall frame 100, the support legs 3 and the barbecue grill 2 are generally in a folded state and are received in a receiving bag (not shown), and the corresponding folded state is shown in fig. 14, 12 and 13.

When the barbecue grill is used, the side wall frame 100, the supporting legs 3, the shelf part 1 and the barbecue grill 2 need to be unfolded as follows.

Unfolding the sidewall frame 100: one hand acts on the front side plate 101 and exerts force outwards, and the other hand acts on the rear side plate 102 and exerts force outwards; then, the outward force acts on the left side plate 103, after the two left side sub-plates 100c of the left side plate 103 are completely unfolded, the left side connecting arm 106 is rotated, so that the bayonet 106a of the left side connecting arm 106 is clamped on the corresponding clamping portion 107, and thus the left side plate 103 is locked in the completely unfolded state; similarly, when the right side plate 104 is outwardly acted, and the two right side sub-plates 100d of the right side plate 104 are completely unfolded, the right side connecting arm 106 is rotated, so that the bayonet 106a of the right side connecting arm 106 is snapped onto the corresponding snapping portion 107, and thus the right side plate 104 is locked in the completely unfolded state.

Unfolding the supporting legs 3: taking out the connecting portion 321 of the second end 3b of the supporting leg 3 from the second large-diameter portion 109a of the second opening 109 of the sidewall frame 100, and rotating the supporting leg 3 downward, so that the supporting leg 3 rotates downward with the first end 3a thereof as a fulcrum, aligning the connecting cover 3211 on the connecting portion 321 of the second end 3b with the first large-diameter portion 108a of the first opening 108, so that the connecting post 3212 of the connecting portion 321 is located in the first large-diameter portion 108a of the first opening 108, after releasing the hand, because the supporting leg 3 has elasticity, the second arm 32 is far away from the first arm 31 of the supporting leg 3, so that the connecting post 3212 of the connecting portion 321 is located in the first small-diameter portion 108b of the first opening 108, and at this time, the connecting cover 3211 of the connecting portion 321 is located outside the first small-diameter portion 108b of the first opening 108 and in the sidewall frame 100, thus completing the unfolding of the supporting leg 3.

Installing the placing part 1: after the placing part 1 is unfolded, the placing part 1 is sleeved outside the rotating shaft 41 through the through hole 11.

Installing the barbecue grill 2: after the grill 2 is unfolded, the second pins 22 of the grill 2 are inserted outside the corresponding rotating shafts 41, and the first pins 21 of the grill 2 are inserted into the insertion holes 100e of the side wall frame 100, at this time, the position-limiting portions 211 of the first pins 21 are supported on the upper flanges 100a of the side wall frame 100.

The food can be roasted by placing charcoal fire on the placing part 1 and placing the food on the roasting rack 2. Because put portion 1 and be flexible metal mesh, charcoal fire is when beginning to ignite because the bottom air is more sufficient, ignites more easily, along with going on of barbecue, the charcoal ash that burns out accumulates in charcoal fire bottom gradually and plays the effect of heat preservation and isolated bottom air, and follow-up charcoal fire can not burn too fast like this yet.

After the completion of the grilling, the grill 2, the shelf part 1, the support legs 3, and the side wall frame 100 are folded in this order as follows.

Folding the barbecue grill 2: referring to fig. 13, the first and second pins 21 and 22 of the grill 2 are rotated to a folded state.

Folding and placing the part 1: referring to fig. 14, the shelf portion 1 is upwardly acted, the shelf portion 1 is separated from the rotary shaft 41, and the shelf portion 1 is folded by winding.

Folding supporting legs 3: referring to fig. 5, the second ends 3b of the supporting legs 3 are taken out from the first openings 108 of the sidewall frames 100, the supporting legs 3 are rotated upward and reversely, and the second ends 3b of the supporting legs 3 are inserted into the second openings 109 of the sidewall frames 100, which is similar to the process of unfolding the supporting legs 3.

Folding the side wall frame 100: referring to fig. 9, 11 and 12, the left connecting arm 106 is rotated to separate the bayonet 106a of the left connecting arm 106 from the corresponding bayonet 107 on the left side plate 101, and similarly, the right connecting arm 106 is rotated to separate the bayonet 106a of the right connecting arm 106 from the corresponding bayonet 107 on the right side plate 104; the inward force acts on the left side plate 103 and the right side plate 104, so that the two left side sub-plates 100c are close to each other and the two right side sub-plates 100d are close to each other; then, the front side plate 101 and the rear side plate 102 are operated again so as to be close to each other.

Finally, the folded barbecue grill 2, the placing part 1, the supporting legs 3 and the side wall frame 100 are all contained in a containing bag, so that the barbecue grill is convenient to carry and store, and has the advantage of small occupied space.
