Description

Technical Field

[0001] This utility model relates to the field of barbecue equipment technology, and in particular to a gas-fired, smokeless barbecue grill. Background Technology

[0002] In the field of barbecue equipment, traditional barbecue grills are usually designed with a central charcoal placement mode or an electric grilling mode. The central charcoal placement mode places the charcoal blocks in the central area inside the grill and uses the heat generated by the burning charcoal blocks to grill multiple sets of skewers around it. The electric grilling mode sets an electric heating rod in the central area inside the grill to grill the skewers on the outer ring. This type of structure is widely used in home barbecues, outdoor dining and other scenarios because of its simple operation and low cost.

[0003] However, charcoal grilling produces a lot of smoke and generates harmful substances that affect human health, making it unsuitable for grilling in the kitchen. Electric grilling, on the other hand, results in meat that is too dry and has a poor taste due to its lower temperature and longer cooking time. Utility Model Content

[0004] To address the problem that charcoal grilling in existing technologies is unsuitable for kitchen grilling, this utility model provides a gas-fired smokeless grill, comprising a base, a gas collecting cylinder mounted on the base, and an outer cylinder fitted around the gas collecting cylinder. The gas collecting cylinder includes an inner cylinder and a water tank at the bottom of the inner cylinder, forming a grilling cavity for placing skewers between the inner and outer cylinders. The inner cylinder has multiple through holes on its side wall and multiple radially arranged fins on its inner wall. The top of the outer cylinder has a grill rack for fixing the skewers. The base is placed on a gas stove, and the skewers in the grilling cavity are cooked by the flame being concentrated by the inner cylinder and the heat being transferred by the fins.

[0005] Specifically, the grill is ring-shaped, and multiple slots are provided in the grill along the radial direction.

[0006] Specifically, the inner wall of the outer cylinder is provided with a boss, and the grill is placed on the boss.

[0007] Specifically, the grill is equipped with a lid.

[0008] Specifically, the base includes legs and a support section. The legs are mounted on the gas stove, the support section is a through-ring structure, and the gas collecting cylinder is mounted on the support section.

[0009] Specifically, a connecting frame is fixed at the four corners of the outer side of the base, and a plug-in block matching the connecting frame is provided at the four corners of the outer wall of the gas collecting cylinder. The plug-in block can be inserted into the connecting frame. A plug-in groove matching the plug-in block is opened at the four corners of the outer cylinder. The plug-in block can be inserted into the plug-in groove.

[0010] Specifically, the outer cylinder is provided with a handle on its side wall.

[0011] In summary, the present invention has the following main advantages:

[0012] This utility model provides a gas-fired smokeless barbecue grill that uses gas as a heat source. It is especially suitable for barbecuing in home kitchens. The inner cylinder concentrates the flames and the fins have good thermal conductivity, which quickly heats the inner cylinder. The skewers placed in the grilling cavity are cooked by heat convection through the through holes on the surface of the inner cylinder and heat radiation from the inner cylinder. It is easy to use. A water tank is set at the bottom of the grilling cavity to collect the oil dripping during the grilling process, preventing the oil from carbonizing and producing smoke, which significantly reduces the smoke generated during the grilling process. At the same time, the water vapor generated by the boiling water can replenish the moisture of the skewers, effectively preventing the skewers from becoming dry due to excessive evaporation of surface moisture during long cooking time.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] The embodiments of this utility model will be described below based on its overall structure.

[0020] A gas-fired smokeless barbecue grill, such as Figures 1-4 As shown, it includes a base 1, a gas collecting cylinder 2, and an outer cylinder 3.

[0021] A gas-fired concentrator 2 is mounted on a base 1. The base 1 includes legs 7 and a support 8. The legs 7 are mounted on the gas stove to ensure the stability of the stove during use. The support 8 is a through-hole ring structure that supports the gas-fired concentrator 2 and creates a certain gap between the gas stove and the gas-fired concentrator 2. The bottom of the gas-fired concentrator 2 corresponds to the burner opening of the gas stove to allow air and the gas stove flame to enter the gas-fired concentrator 2. The gas-fired concentrator 2 includes an inner cylinder 4 and a water tank 5 located at the bottom of the inner cylinder 4. The upper and lower ends of the inner cylinder 4 are open. An outer cylinder 3 is fitted around the outer periphery of the inner cylinder 4, forming a grilling cavity 9 where skewers are placed. Multiple through holes 14 are evenly distributed on the side wall of the inner cylinder 4, allowing hot air to enter the grilling cavity 9. The inner wall of the inner cylinder 4 is provided with multiple radially arranged fins 6, which are distributed in a ring array. The inner cylinder 4 guides the flames to flow axially, creating a converging effect and preventing heat from spreading irregularly in all directions. The fins 6 are made of metal with good thermal conductivity. The lower end of the fins 6 is heated by the smoke and flames, and the fins 6 increase the contact area with the hot air. Heat is transferred through the fins 6 to the outer wall of the inner cylinder 4. The skewers placed in the grilling cavity 9 are cooked through the thermal convection of the hot air and the thermal radiation of the inner cylinder 4.

[0022] The water tank 5 is located at the bottom of the grilling cavity 9. During use, an appropriate amount of water can be injected into it. The grease dripping from the skewers falls into the water tank 5, facilitating grease collection and preventing the formation of harmful substances and fumes due to high-temperature carbonization, thus making the grilling process healthier and more environmentally friendly. Simultaneously, the steam generated by the boiling water in the water tank 5 replenishes the moisture of the skewers, preventing excessive evaporation of surface moisture during prolonged cooking, which would cause the skewers to lose their internal juices and become dry.

[0023] The outer cylinder 3 has handles 18 on its side walls and protrusions 12 on its top inner walls. A ring-shaped grill rack 10 is placed on the protrusions 12, and the size of the grill rack 10 matches the size of the outer cylinder 3. A cover 13 is provided on the ring-shaped grill rack 10. Multiple slots 11 are arranged radially in the grill rack 10. The skewers are hung upside down and placed in the slots 11, with the handles of the skewers engaging to facilitate turning and rotating the skewers for cooking. Simultaneously, the slots 11 act as vents for hot air to escape during grilling. The cover 13 is closed during grilling to retain heat within the grilling cavity 9, minimizing heat loss.

[0024] A connecting frame 15 is provided at the four corners of the outer side of the support part 8. A plug-in block 16 matching the connecting frame 15 is provided at the four corners of the outer wall of the gas collecting cylinder 2. The plug-in block 16 can be inserted into the connecting frame 15 to install the gas collecting cylinder 2 onto the base 1. A plug-in groove 17 that mates with the plug-in block 16 is provided at the four corners of the outer cylinder 3. The plug-in block 16 can be inserted into the plug-in groove 17 to install the outer cylinder 3 onto the outer periphery of the gas collecting cylinder 2.

[0025] In use, place the base 1 on the gas stove and install the gas concentrator 2 on the base 1. Cover the gas concentrator 2 with the outer cylinder 3. Place the handle of the skewers upside down in the grilling cavity 9. Turn on the gas stove and close the cover 13. The flames generated by the gas stove enter the gas concentrator 2 and heat the fins 6. The gas concentrator 2 can effectively concentrate the flames and prevent the heat from spreading irregularly in all directions. The heat is transferred to the inner cylinder 4 through the fins 6. The hot air enters the stove through the bottom of the gas concentrator 2 and is transferred to the grilling cavity 9 through the through hole 14. The skewers can be turned over by rotating the handle to grill them evenly in the grilling cavity 9.
