Description

Technical Field

[0001] The invention relates to a barbecue oven, in particular to a drum-type meat skewer barbecue oven. Background Art

[0002] The existing method of grilling meat skewers is generally to manually place a number of skewers on burning charcoal and flip them over for grilling. When sprinkling or brushing oil, it is necessary to sprinkle the seasoning or oil on the entire skewers, grasp the skewers with both hands and divide them into two parts, and then squeeze them together so that the seasoning is fully adhered to each skewer. This operation needs to be performed many times during the grilling process. This grilling method allows the heat under the skewers to directly contact the surface of the food, thereby providing a richer taste. However, this method has a heavy operating burden, low baking efficiency, and is not easy to bake evenly. There are some existing devices that use mechanical devices to flip the skewers for grilling.

[0032] Please see attached Figure 5 To Attachment Figure 7As shown, the inner barrel 142 is composed of an inner barrel bottom 1421, an inner barrel lifting rib 1422, an inner barrel bottom barrel wall 1423, an inner barrel top barrel wall 1424, a paddle group 1425, and a top connecting ring 1426; the inner barrel bottom 1421 is a circular flat plate and its radius is slightly smaller than the distance from the inner surface of the outer barrel lifting rib 1412 to the center of the outer barrel bottom 1412; the inner barrel lifting rib 1422 is a round rod with the same diameter as the outer barrel lifting rib 1412 and the length does not exceed the length of the skewers, and the inner barrel lifting rib 1421 is a circular flat plate and its radius is slightly smaller than the distance from the inner surface of the outer barrel lifting rib 1412 to the center of the outer barrel bottom 1412; the inner barrel lifting rib 1422 is a round rod with the same number and diameter as the outer barrel lifting rib 1412 and the length does not exceed the length of the skewers. One end of the inner barrel bottom 1421 is connected to the surface of the inner barrel bottom 1421 and is upright and evenly distributed on the outer circle of the inner barrel bottom 1421; the inner barrel bottom wall 1423 and the inner barrel top wall 1424 are cylindrical pipes with a plurality of small holes on the surface, and the hole positions correspond to the water inlet of the water inlet pipe; the inner barrel bottom wall 1423 and the inner barrel top wall 1424 have the same radius and are smaller than the distance from the inner wall of the inner barrel lifting rib 1422 to the center of the inner barrel bottom 1421 minus the skewer radius; the inner barrel bottom wall 142 3 and the inner barrel top barrel wall 1424 are vertically arranged at the center of the inner barrel 142, the inner barrel bottom barrel wall 1423 is connected to the inner barrel bottom 1421, the inner barrel top barrel wall 1424 is fixed to the top connecting ring 1426, and the distance from the upper point of the lower end of the inner barrel bottom barrel wall 1423 to the farthest point of the lower end of the inner barrel top barrel wall 1424 is less than the length of the skewer. Such an arrangement can ensure that when the drum assembly 14 is in an inclined state, no matter how the skewer swings, it will be confined to the space enclosed by the upper and lower barrel walls. ; The paddle group 1425 is a rectangular structure and its length does not exceed the inner barrel top wall 1424 and the inner barrel bottom wall 1423. The paddle group 1425 protrudes from the corresponding barrel wall surface to a certain height and the upper and lower groups of paddle groups 1425 correspond one to one in the vertical direction; the top connecting ring 1426 is an annular flat plate structure, the inner circle of the top connecting ring 1426 is connected to the top of the inner barrel 142, and the outer circle of the top connecting ring 1426 is connected to the top of the inner barrel lifting rib 1422.

[0033] The screw rod group 15 is composed of two vertically arranged screw rods and a horizontally arranged square tube to form a U-shaped structure. The square tube can move up and down in the vertical direction along the screw rod and can be fixed by the nut on the screw rod; the opening of the U-shaped structure faces upward, the distance between the two screw rods is slightly larger than the diameter of the roller group 14, and the length of the screw rod is slightly smaller than the height of the inner wall of the furnace body 1; the top end of the screw rod group 15 is fixed to the top of the inner wall of the furnace body 1, and the fixing point is at the front of the furnace body 1 near the furnace door.

[0034] A pair of universal balls 16 are provided at both ends of the bottom of the U-shaped screw rod assembly 15, and the spherical surface of the universal ball 16 contacts the outer wall of the open end of the outer barrel 141 of the roller assembly 14, so as to support the open end of the roller assembly 14. The roller assembly 14 can be adjusted in pitch along the axial direction by adjusting the height of the horizontal square tube in the furnace.

[0035] An oil receiving box 7 is provided at the lower part of the drum assembly 14, and the oil receiving box 7 can collect the oil dripping from the drum.

[0036] The gear chain group 9 consists of a pair of gears and a chain connecting the gears. The gear located at the upper part is connected to the bearing seat fixing ring assembly 12, the coupling 11, and the motor 8 in sequence through the shaft, and the gear located at the lower part is connected to the bearing seat fixing ring assembly 12 and the universal joint 13 in sequence through the shaft.

[0037] The bearing seat fixing ring assembly 12 located at the lower part passes through the furnace body 1 , one end of the bearing seat fixing ring assembly 12 is on the outer side of the furnace body 1 , and the other end is on the inner side of the furnace body 1 .

[0038] When in use, the inclination angle of the drum set 14 can be adjusted by adjusting the horizontal square tube of the screw rod set 15 up and down. The drum set 14 is tilted forward and backward to ensure that the skewers in the drum set 14 will not be thrown out from the opening. However, if the drum set 14 is tilted too much, it is easy for the food on the skewers to slide down and fall off the skewers. At the same time, the friction between the head of the skewers and the bottom of the drum set 14 increases, and the skewers are easy to rotate around the head of the skewers in the drum set 14, which will cause the skewers to be staggered together, and the baking process cannot be carried out. After adjusting the drum set 14, fill the oil receiving box 7 with clean water, and finally ignite the charcoal in the fuel box 2. The hot air flow in the furnace body 1 will first rise, and after encountering the top of the inner wall of the furnace body 1, it will turn back and flow downward, and be discharged from the lower inlet of the exhaust pipe 5 along the exhaust pipe 5, and all parts in the furnace will be evenly heated. The required target temperature can be set by the temperature controller. When the temperature in the furnace exceeds the set temperature, the fan starts to send cold air into the furnace. Due to the introduction of cold air, the temperature in the furnace body 1 begins to drop. When the temperature is lower than the set temperature, the fan is turned off and the furnace begins to heat up. In this way, the temperature in the furnace can be controlled to fluctuate up and down within the set temperature. The cold air duct 3 opens upward and is close to the fuel box 2, which makes it easier for the cold air to fully mix with the hot air above the fuel box 2. At the same time, the cold air entering can also cool the fuel box 2. When the temperature rises, turn on the water pump, and the water inlet pipe 6 will drip clean water from the top. When the temperature in the furnace reaches the appropriate temperature, put the skewers into the inner barrel 142, open the furnace door, and put the inner barrel 142 into the outer barrel 141 from the opening of the drum group 14. At this time, you can sprinkle or add oil. Then close the furnace door, turn on the motor switch, and through the gear chain assembly 9, the motor 8 drives the outer barrel 141 to start rotating, and the outer barrel 141 then drives the inner barrel 142 to rotate. The skewers in the inner barrel 142 are lifted and then thrown down by the action of the paddle group 1425. The two ends of the skewers are placed on the upper and lower barrel walls of the inner barrel 142, and the food to be grilled is suspended in the air and does not contact any part of the different rollers in the drum group 14, so there is no possibility of adhesion to the barrel body, which fully simulates the effect of manually placing the skewers on the charcoal fire for grilling. During this process, the skewers squeeze and rub against each other, and the seasoning and oil can be evenly distributed between the meat pieces. The temperature distribution in the furnace is uniform, and the heating opportunities of each skewers and the meat pieces at different positions of each skewers are not much different. The grilling effect of a single skewers of grilled meat is consistent in the front and back directions, and the grilling effects of different skewers can also be consistent. After being heated, the oil in the drum group 14 will drip downward into the oil receiving box 7, and will not contact the hot charcoal, so no choking smoke will be generated, and the entire grilling process is smokeless and environmentally friendly. A speed regulator device can be added to control the speed of the motor 8 and then control the rolling speed. The speed of the drum group 14 is related to the temperature in the oven. The speed can be increased when the temperature is set high, and vice versa. The oven door can be opened at any time to add materials during the baking process.As the drum set 14 rotates, the clean water dripping from the water inlet pipe 6 will fall from the water inlet of the barrel wall 1423 at the bottom of the inner barrel and the barrel wall 1424 at the top of the inner barrel, and the clean water will fall on the upper and lower parts of the skewers, cooling the upper and lower parts of the skewers, which can prevent the bamboo skewers from being over-carbonized. Ensure the quality of the product. The clean water that does not enter the water inlet will remain on the surface of the barrel wall, which can be cooled to prevent deformation. When the baking is finished, turn off the motor power supply and the drum set 14 stops rotating. At this time, open the furnace door and take the inner barrel 142 out of the outer barrel 141. Put in the next inner barrel 142 prepared in advance and continue baking. During the baking process, the high-temperature gas can directly contact the surface of the food, and the food will be heated at a higher temperature, which will bring a rich taste. The baking process fully simulates the operation of manually placing the skewers above the charcoal fire. There is no choking smoke in the entire baking process. The manual operation only requires simple operations such as putting the skewers in and out of the oven and adding materials directly in the middle. The most labor-intensive part is completely handed over to the machine to complete, which will greatly improve labor efficiency and also obtain consistent skewers. When in use, the inner barrel is sleeved in the outer barrel 141 and rotates and rolls under the action of the lifting ribs of the outer barrel 141. This design is to facilitate continuous baking, but it does not mean that the outer barrel 141 is required to achieve the above effect. In fact, the inner barrel structure alone can also achieve the above purpose.

[0039] In the present invention, bamboo skewers and iron skewers are universal for grilling. At present, when grilling manually, the skewers are directly placed on charcoal fire for grilling, and the bamboo skewers cannot be used due to the influence of high temperature. The present invention solves the shortcomings of the prior art and is conducive to reducing costs.

[0040] In summary, the present invention can realize the simultaneous baking of a large number of skewers in the oven, simulating manual flipping and baking on charcoal fire, and can conveniently complete the distribution of seasonings and oils on the surface of the skewers, so that the baking effect is consistent and the surface seasonings are evenly distributed. The entire baking process is automatically completed in the oven without excessive manual participation, and is convenient for production and use.

[0041] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the present invention specification, or directly or indirectly applied to the technical field attached to other related products, are also included in the patent protection scope of the present invention.
