Description

Technical Field

[0001] This utility model relates to the field of barbecue grill technology, and in particular to a one-wire variable pitch barbecue grill. Background Technology

[0002] A barbecue grill is a cooking device used for grilling various foods. Common types include charcoal grills, gas grills, and electric grills. Electric grills convert electrical energy into heat energy for grilling, making them very convenient to use – simply plug them in. Temperature control is often more precise, and some electric grills even have constant temperature and timer functions, ensuring better grilling results. However, currently, when grilling skewers, the distance between them cannot be accurately controlled to ensure optimal heating above the heating elements. When adding seasoning, all the skewers must be slowly gathered together before adding the seasoning, which results in uneven distribution. Furthermore, the seasoning needs to be spread evenly afterward, making the process cumbersome and reducing grilling efficiency. Additionally, traditional grills have limitations because the skewers vary in length, making it impossible to grill shorter skewers on the long span of the grill. Moreover, traditional grills cannot effectively collect and utilize the dissipated heat. To address these issues, we propose a single-wire variable-pitch barbecue grill. Utility Model Content

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-5As shown, a one-line traction variable-pitch grill includes a double-tank oven body 1. Heat exchange coils 2 are fixedly installed between the inner and outer tanks on the front and rear walls, lower wall, and one side wall of the double-tank oven body 1, with the heat exchange coils 2 fixedly installed close to the surface of the inner tank. A variable-pitch structure 3 is fixedly installed at the upper port of the double-tank oven body 1 near the edge of the rear surface. Hand-operated adjustable pitch structures 4 are fixedly installed at the upper port of the double-tank oven body 1 near both sides. Mounting eaves 5 are fixedly installed on the outer two sides and the rear surface of the double-tank oven body 1 near the upper port. A PLC control unit is fixedly installed on one side of the double-tank oven body 1. The panel 6 and the interior of the double-coil oven body 1 are fixedly installed with heating rods 7 and oil trays 8. The oil trays 8 are embedded in the bottom of the interior of the double-coil oven body 1. The oil trays 8 contain water that can float oil stains, reducing the trouble of cleaning. At the same time, the evaporation of water can increase the moisture of the roasted meat and make it tender. The interior of the double-coil oven body 1 is embedded above the heating rods 7 and has a material tray 9. During normal grilling, the material tray 9 needs to be pulled out to prevent the barbecue on the material tray 9 from not being heated. It is only inserted to collect when seasoning and oiling are needed. The upper surface of the mounting plate 5 is fixedly installed with a heat preservation cover 10.

[0021] A first embedment opening 11 is provided on the other side surface of the dual-tank furnace body 1, and a second embedment opening 12 is provided on the other side surface of the dual-tank furnace body 1 above the first embedment opening 11. L-shaped base supports 13 are fixedly installed on the front and rear surfaces of the internal interior of the dual-tank furnace body 1, near the port of the second embedment opening 12. A flue gas vent 14 is provided on the rear surface of the dual-tank furnace body 1. One end of the heat exchange coil 2 is connected to a water inlet connector 21, and the other end is connected to a water outlet connector 22. The water inlet connector 21 is located on the rear surface of the dual-tank furnace body 1, and the water outlet connector 22 is located on the rear surface of the dual-tank furnace body 1. The front surface of body 1 has a water inlet connector 21 connected to tap water via a pipe; the variable pitch structure 3 includes a slide rail 31, a slider 32, a bearing seat 33, a small motor 34, a flat-mouth plug-in groove 35, a limiting steel rope 36, and a power supply line 37. A slider 32 is slidably mounted on the surface of the slide rail 31. Multiple sliders 32 are provided as needed. A bearing seat 33 is fixedly mounted on the upper surface of each slider 32. A small motor 34 is fixedly mounted on the upper surface of each slider 32 behind the bearing seat 33. The output end of the small motor 34 passes through the bearing seat 33 and is fixedly connected to the flat-mouth plug-in groove 35. Multiple... The sliders 32 are connected in series by equal-length limiting steel ropes 36, and one slider 32 near one end is connected to the hand-held oven adjustment structure 4 via the limiting steel rope 36. A pull ring is fixedly installed on the upper surface of the slider 32 near the other end. The power supply line 37 connects multiple small motors 34 in parallel, and one end of the power supply line 37 is electrically connected to the PLC control panel 6. The hand-held oven adjustment structure 4 includes a slide rod 41, a linear bearing 42, a square rod 43, and a limiting groove 44. The slide rod 41 is fixedly installed on the upper port of the double-walled oven body 1 near both sides, and the surface of the slide rod 41 is movably fitted with... A linear bearing 42 is installed, and a square rod 43 is connected between two linear bearings 42. Multiple limiting grooves 44 are opened on the upper surface of the square rod 43. The limiting grooves 44 are evenly distributed on the square rod 43. When the variable pitch structure 3 is working, the square rod 43 is moved to the bottom of the flat-mouth insertion groove 35 to avoid affecting its normal operation. The surface of the PLC control panel 6 is provided with a power supply socket 61. The oil receiving tray 8 is embedded into the bottom surface of the double-wall furnace body 1 through the first embedding port 11, and the material receiving tray 9 is embedded into the L-shaped base 13 inside the double-wall furnace body 1 through the second embedding port 12.

[0022] It should be noted that this utility model is a one-wire variable-pitch barbecue grill. During use, the water inlet connector 21 is connected to tap water, the water outlet connector 22 is connected to a faucet, and the power supply socket 61 is connected to AC power via a power cord. When using the variable-pitch structure 3 for grilling, the flat-handled bamboo skewer handle needs to be inserted into the flat-mouth insertion slot 35. Then, the slider 32 is pulled open using the pull ring on one end. The slider 32 unfolds evenly under the constraint of the limiting steel rope 36, and is positioned precisely between the multiple heating rods 7 below. This not only ensures effective and comprehensive heating but also prevents oil stains from the meat from dripping onto the heating rods 7 and producing smoke. After unfolding, the heating rods 7 and the small motor 34 can be simultaneously activated via the PLC control panel 6. When adding ingredients or oil, the slider 32 can be retracted using the pull ring. This allows the skewers to be gathered above the L-shaped base 13. At this time, the receiving tray 9 is embedded to collect dripping oil and seasonings, preventing them from falling onto the heating rod 7. During this time, the skewers can be manually rotated slowly to achieve even coating. When manually grilling skewers without flat handles, the linear bearing 42 can be adjusted according to the length of the skewers to adjust the distance between the front edge of the double-walled furnace 1 and the square rod 43. This allows skewers of various lengths to be placed on the limiting groove 44 on the square rod 43 for grilling. During grilling, the water tap is turned on, and tap water enters the heat exchange coil 2 to absorb the heat absorbed by the inner wall of the double-walled furnace 1 and is then discharged from the tap. This not only recovers and utilizes the lost energy to save energy, but also avoids the risk of burns caused by excessively high temperatures on the outer wall of the double-walled furnace 1.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
