Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1, the circular rotary oven comprises a circular oven body and an upper cover matched with the circular oven body, wherein a gap is reserved between the oven body and the upper cover; the furnace wall of the furnace body is formed by double-layer stainless steel embedded heat preservation cotton, so that heat is effectively preserved. The furnace body bottom is fixed with the supporting leg to connect the gyro wheel, the convenient removal.

The center of the bottom of the furnace body is raised into a base, a combustion chamber connected with an external heat supply system is arranged on the base, and a heating cover covers the combustion chamber; a horizontal cross support frame is symmetrically fixed on the inner wall of the furnace body in the circumferential direction, and a vertical support column is fixed above the cross point of the cross support frame;

the upper cover is formed by hinging a central beam 2 and two opening and closing covers 3 which are symmetrical on two sides through two sections of force hinges, the beam is used as a central connecting plate, a central rotating shaft 1 at the lower part of the center of the beam is connected with a supporting column through a rotating bearing, and the two opening and closing covers are provided with handles to drive the upper cover to rotate along the bearing; two outer sides of the bottom of the cross beam are fixed with baking net frames matched with the furnace body, the baking net frames are inverted U-shaped clamping grooves 4 and cover the furnace wall of the furnace body, one side of each baking net frame in the furnace body is welded with a circle of fixing ring, a horizontal baking net is placed on each fixing ring, a cross bar is welded between two ends of each fixing ring, and a plurality of short clamping bars are welded on each fixing ring to prevent a baking tray or a baking string from sliding off; the opening and closing cover is seamlessly attached to the baking net rack; when the barbecue grill is used for placing the barbecue string, the opening and closing cover can be pressed on the prod without influencing rotation.

As the preferred embodiment, the shape of the baking net is in a grid shape or a ring shape or a horizontal strip shape, and the baking net can be switched at will, and different baking nets can be selected according to actual needs. At least two ray-shaped baking net support bars 5 are fixed between the central rotating shaft 1 and the U-shaped clamping grooves 4 of the baking net rack and are used for supporting and fixing a baking net 6; the roasting net 6 may be an integral one, or may be formed by splicing a plurality of small fan-shaped net disks, the net disks are in a grid shape, an annular shape or a horizontal strip shape, for example, the roasting net 6 may be formed by splicing a grid-shaped net disk with 1/2 circular arcs and an annular net disk with 1/2 circular arcs, and is suitable for foods with different shapes. When the barbecue grill is used, the heat supply system supplies energy for the combustion of the combustion chamber, the combustion heat is upwards radiated into the whole oven body to supply to the upper barbecue tray, and the barbecue food placed on the upper barbecue tray is heated by adopting the hot air circulation method. The handle on any opening and closing cover is rotated to drive the whole upper cover to rotate along the bearing, so that people can freely control food on the baking trays on two sides without moving. Meanwhile, the baking tray frame with the inverted U-shaped clamping groove covering the furnace wall of the furnace body can drive the baking tray to rotate freely around the furnace body, so that the gap between the upper cover and the furnace body is shielded as much as possible, heat overflow loss is effectively prevented, the heat efficiency is improved, the temperature is increased quickly, and the fuel cost is reduced. The groove outside the base of the furnace body is filled with water to form a water tank for dissolving the flying ash in the combustion chamber and the falling slag from the upper baking tray. And a drain hole and a water distribution valve are arranged at the bottom of the furnace body, so that the furnace body can be conveniently drained after being cleaned. In addition, an overflow hole is arranged on the furnace wall below the base, so that the water level in the water tank is prevented from being too high to exceed the combustion chamber.

In addition, in order to facilitate effective temperature control, a temperature sensor is fixed at the upper part in the furnace body and is connected with a control panel of an external heating system, so that the temperature is controlled in real time. As the preferred embodiment, the heating system comprises a feeding mechanism for supplying combustion heating, gas infrared heating and electric heating wire heating to fruit trees or biomass particles, and is suitable for various heat sources and wide in application range.

The structure of the utility model not only occupies small area, is portable and movable, is simple and easy to operate, burns fully and greatly reduces pollution, but also improves burning rate and reduces cost; in addition, the traditional open fire barbecue is optimized into a healthier heat transfer baking form, and meanwhile, the unique smoke and fire flavor of the quick high-temperature baking is ensured, so that the physical health of the eaters is effectively ensured while the eaters taste delicious food.

The above description is only a preferred embodiment of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and enhancements can be made without departing from the principles of the invention, and such modifications and enhancements are intended to be within the scope of the invention.
