Description

Technical Field

[0001] The present invention relates to the technical field of smokeless charcoal barbecue skewer grills, and specifically to an upright charging automatic smokeless charcoal barbecue skewer grill that is easy to clean, maintain and portable. Background Art

[0002] Barbecue is one of the cooking methods loved by the public nowadays. Therefore, a barbecue grill is an essential barbecue tool. Currently, barbecue grills are not limited to being used in barbecue restaurants. Companies, families, and individuals will also prepare their own barbecue grills to meet their dietary needs and the sense of participation in their own barbecues.

[0003] There are various existing grills. The most common ones are horizontal charcoal grills and horizontal electric grills. However, the biggest problem with horizontal grills is that the barbecue grease directly drops onto the charcoal, generating thick smoke, which not only chokes people but also pollutes the environment.

[0004] To solve the above problems, barbecue equipment is gradually being upgraded, and thus some upright smokeless barbecue skewer grills have emerged. During the barbecue process of upright grills, oil does not drip onto the heat source, so basically no oil fume is generated. However, almost all existing upright smokeless grills in the current technology adopt the method of electric heating for barbecue. For example, in the Chinese utility model patent with the publication number CN211432406U and the patent name "An Upright Barbecue Grill", it "includes a base, a tray, a reset device, an electric switch, and a furnace cover. By providing a reset device on the base for supporting the tray...", which uses a heater for heating and barbecue. People generally believe that the taste of electric heating barbecue is not as good as that of charcoal barbecue. At the same time, the method of electric heating barbecue can only be used in places with power sources. It cannot be used in the wild and can only be used by carrying a power source large enough. However, purchasing a power source requires a certain cost, and it is very inconvenient to carry and charge. In addition, the counterbore structure and function of the installation sleeve for fixing the skewers in the above-mentioned existing patent are simple, and it can only insert skewers of one model, and it is very difficult to align and install, with poor applicability and compatibility.

[0053] The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, which are as follows:

[0054] Embodiment 1

[0055] Before the present invention is used, first, the entire skewer roasting furnace is assembled and prepared. Place the motor compartment 2 in a flat position, seat the oil drip pan 4 on the stepped groove 21 at the upper end of the motor compartment 2, and fill the oil drip pan 4 with water. Place the charcoal cage support 5 at the center position inside the oil drip pan 4, seat the mesh charcoal cage 9 on the charcoal cage support 5, and multiple clamping plates 51 just radially clamp the mesh charcoal cage 9. Place the charcoal cage ash layer 10 at the bottom inside the mesh charcoal cage 9. Then, put the barbecue compartment 8 on from the top of the mesh charcoal cage 9, and the bottom 83 of the compartment is sleeved outside the oil drip pan 4 and seats on the upper end face of the motor compartment 2. Place the ignited barbecue charcoal in the mesh charcoal cage 9, and cover the charcoal cage cover plate 11 on the top of the mesh charcoal cage 9. Particularly, a limit protrusion can be provided on the outer side wall of the oil drip pan 4, and limit grooves matching the limit protrusion are provided in the stepped groove 21 of the motor compartment 2 and at the bottom of the barbecue compartment 8. Align and install, and it can ensure that the through hole 42 of the water nozzle 41 of the oil drip pan 4 is aligned with the skewer support plate 31 on the rotation driving mechanism 3, which is convenient for the subsequent installation of the skewer support assembly 6.

[0056] After the assembly preparation is completed, the personnel can carry out the barbecue operation. Before the present invention is used, start the rotation driving mechanism 3 in the motor compartment 2, and its multiple rotation ends drive the skewer support plate 31 to rotate. Since the transmission rod 61 in the skewer support assembly 6 passes through the water nozzle 41 of the oil drip pan 4 and is clamped with the skewer support plate 31, the skewer support plate 31 can drive the transmission rod 61, the oil receiving umbrella 62 connected to the transmission rod 61, and the bearing plate 63 connected to the oil receiving umbrella 62 to rotate. The personnel can install the food skewers with skewers. Hold the top of the skewer, first insert the bottom of the skewer into the long hole 65 of the bearing plate 63. Generally, flat iron skewers are inserted into the long hole 65. The long holes 65 are arranged in a matrix, which is convenient for the personnel to insert from various angles and is also suitable for skewers of different widths. Thinner skewers can be inserted into the round holes 66. After the lower end of the skewer is inserted, the personnel radially adjust the top of the skewer to make its top slide into the spiral groove 84 of the corresponding top plate 81. The spiral groove 84 is designed with a larger outer opening and a smaller inner opening, which is convenient for the personnel to put on the skewers and the skewers can be stably installed. Of course, due to the gravity of the skewers and the food themselves and the friction between the bottom of the skewers and the bearing plate 63, round skewers can also be inserted into the long hole 65, which is more convenient for the personnel to operate. This design in the present invention has stronger compatibility than the prior art, is more suitable for the personnel to quickly install food skewers, and improves the user experience. The rotation of the bearing plate 63 can drive the food skewers to rotate, and its own rotation can achieve the purpose of uniform barbecue. In addition, a barbecue basin can be placed at the center position of the charcoal cage cover plate 11 to make soup foods and rinsed foods, with comprehensive functions.

[0057] During barbecuing, the user closes the glass door 7. Of course, it is optimal to use heat-insulating glass. Each glass door 7 is provided with a door lock 71. Closing the door reduces heat loss and accelerates the barbecuing speed. The high-temperature charcoal fire will cause the meat food to release oil or the pickling seasonings of the food to fall off. The oil will fall vertically downward and land on the receiving plate 63. The long holes 65 and round holes 66 on the receiving plate 63 also have a certain oil-guiding function, and the oil will continue to fall and land on the oil-receiving umbrella 62. Since the oil-receiving umbrella 62 is a hemispherical shell and its diameter is larger than the diameter of the waterproof nozzle 41 at its bottom, the oil falling from the oil-receiving umbrella 62 directly slides into the water in the oil-receiving tray 4, without generating oil fumes, thus not polluting the environment and not choking the user. At the same time, it is convenient for subsequent cleaning, preventing the oil from flowing along the skewers and the transmission rod 61 into the motor compartment 2. The water in the oil-receiving tray 4 also has the function of isolating the heat transfer between the upper barbecue compartment 8 and the motor compartment 2. In addition, the ash of the barbecue charcoal in the mesh charcoal cage 9 can fall through the ash holes 102 to the bottom of the mesh charcoal cage 9, ensuring the full combustion of the barbecue charcoal. At the same time, the air holes 111 on the charcoal cage cover 11 also contribute to the full combustion of the barbecue charcoal, improving the barbecue efficiency.

[0058] After the food skewers are cooked, the user can take out the top of the skewer from the spiral groove opening 84, take out the food skewers, and then put in the next food skewer, so as to achieve the purpose of barbecuing and eating at the same time, without the user having to keep watching all the time, providing great convenience for the user.

[0059] After the barbecuing is over, the user uses tools to remove the charcoal cage cover 11. There may be lifting lugs 112 provided at the edge of the upper surface of the charcoal cage cover 11, which is convenient for the user to grip. Use tools to take out the mesh charcoal cage 9, extinguish the remaining charcoal fire. After waiting for the barbecue compartment 8 of the skewer grill to cool down, remove it, pull out the oil-receiving tray 4, and then the skewer support assembly 6 can be removed together, and then it can be cleaned. During use, the motor compartment 2 will not be polluted and does not need to be cleaned. Only the oil stains on the oil-receiving tray 4 and the skewer support assembly 6 need to be cleaned, which is convenient for cleaning.

[0060] Compared with the prior art, in the present invention, a charcoal cage support 5, a mesh charcoal cage 9 and a charcoal cage cover 11 are sequentially arranged on the oil-receiving tray 4 and at the central position in the barbecue compartment 8 to hold the barbecue charcoal, enabling charcoal barbecuing, with a better taste. The vertical design does not generate oil fumes, does not pollute the environment, does not choke the user, does not require an external large power supply, and is very convenient for outdoor use. Moreover, a skewer support assembly 6 with stronger compatibility is inserted into the through hole 42 of the waterproof nozzle 41 of the oil-receiving tray 4, which can be applicable to skewers of different models, facilitating the installation of the skewers for barbecuing and improving the convenience of use for the user.

[0061] Embodiment 2

[0062] On the basis of Embodiment 1, a columnar partition net 91 is arranged at the central position inside the net-shaped carbon cage 9. A connecting plate 92 is fixedly arranged at the top of the columnar partition net 91. The connecting plate 92 can be matched with and clamped into a clamping groove arranged on the inner side wall of the upper end of the net-shaped carbon cage 9 (not shown in the figure). Those skilled in the art can understand that the carbon cage cover plate 11 can cover the top of the columnar partition net 91 and the net-shaped carbon cage 9. When in use, the barbecue charcoal is placed in the gap between the columnar partition net 91 and the net-shaped carbon cage 9. In this way, not only a large amount of barbecue charcoal can be saved, but also other foods such as corn and sweet potatoes can be roasted at the central position of the columnar partition net 91, with comprehensive functions.

[0063] Embodiment 3

[0064] On the basis of Embodiment 1, a hexagonal groove is formed in the skewer support plate 31. The transmission rod 61 is arranged in a hexagonal prism shape. The bottom of the transmission rod 61 can be inserted into the groove in a matching manner and is rotationally driven through circumferential clamping of the hexagon. A reduced opening 67 is arranged at the bottom of the transmission rod 61 to facilitate the insertion of the transmission rod 61. Of course, to avoid accidentally taking out the skewer support assembly 6 when removing the skewer, the skewer support plate 31 and the transmission rod 61 can also be made in a spring bead clamping manner. Spring beads are arranged on the transmission rod 61, and sockets and bead grooves are arranged on the skewer support plate 31. It can be selected according to the actual use situation, not limited to the above two methods.
