Description

Technical Field

[0001] This utility model relates to a gas-fired brazier table, and more particularly to a dual-purpose gas-fired brazier table. Background Technology

[0002] The brazier table is a common piece of furniture found in northern China, Japan, South Korea, and parts of Europe, used indoors during cold winters. A typical brazier table consists of a brazier and a table body. The brazier is located in the center or below the tabletop, and cooking or heating food is achieved by burning fuel inside it. While the burning fuel in the brazier provides some warmth, the heat primarily rises, meaning the area heated is limited to the space above the tabletop. In cold winters, people need to keep their feet warm, necessitating the use of a separate foot warmer system. This additional system requires a separate combustion system, resulting in a significant footprint. Therefore, designing a brazier table that integrates both functionality and space-saving heating has become a pressing issue. Utility Model Content

[0003] The purpose of this invention is to provide a dual-purpose gas-fired brazier table. This invention has the advantage of occupying a small area.

[0004] The technical solution of this utility model: A dual-purpose gas-fired brazier table includes four table legs distributed at the four corners, a tabletop installed between the tops of the four table legs, and a gas cylinder located below the tabletop. The tabletop has a mounting groove in the center, within which a brazier with an open top is installed. A first burner is installed inside the brazier. A partition is provided between each pair of adjacent table legs, and a protective plate is vertically installed on the top surface of each partition between adjacent table legs. A hollow combustion channel is provided between all the protective plates on the top surface of the partition, with multiple evenly distributed through holes on the outer surface of each combustion channel. A second burner is installed inside the combustion channel. A main control plate is located directly below the combustion channel between two table legs, and a first igniter connected to the first burner is installed on the main control plate. A second igniter connected to the second burner is located on one side of the first igniter, and both the second and first igniters are connected to the gas cylinder. The first and second igniters are integrated into one unit via the main control panel, allowing both to be used simultaneously or independently, thus increasing flexibility. The first and second burners are mounted separately via a tabletop brazier and gas channel, with the brazier and gas channel interlocking vertically, resulting in a more compact overall structure and a smaller footprint compared to current single-function brazier tables. Furthermore, the first burner, positioned on the tabletop with its gas outlet on top, functions as a standard brazier table. The second burner, located below the tabletop in a ring shape, provides heating from all sides, effectively functioning as a heater. This combines the brazier table and heater into a single unit. When the first burner is not in use, the table itself functions as a regular table, making the brazier table highly versatile.

[0005] In the aforementioned dual-purpose gas fire pit table, the gas cylinder is equipped with a main gas supply pipe, and a pressure reducing valve is installed on the main gas supply pipe; the end of the main gas supply pipe is equipped with a first branch pipe connected to the first igniter, and a first safety valve is installed on the first branch pipe; a second branch pipe is equipped with a second safety valve on one side of the first branch pipe connected to the second igniter; the pressure reducing valve can reduce and stabilize the gas pressure output from the gas cylinder, ensuring operational stability; the first thermocouple and the second thermocouple can be used to detect whether the first burner and the second burner are working properly, thereby preventing accidental flameout, gas leakage, or even explosion, ensuring safety during use.

[0006] In the aforementioned dual-purpose gas fire basin table, a first thermocouple is installed on the first burner, and the first thermocouple is electrically connected to a first safety valve; a second thermocouple is installed on the second burner, and the second thermocouple is electrically connected to a second safety valve.

[0007] In the aforementioned dual-purpose gas fire basin table, a cover plate is installed on the top surface of the tabletop fire basin to cover the open top surface of the tabletop fire basin, and a handle groove is provided in the middle of the top surface of the cover plate; by installing a cover plate on the top surface of the tabletop fire basin, the top surface of the tabletop fire basin can be covered by the cover plate, so that the entire tabletop can be used as a normal table when the first burner is not in use; and the handle groove on the cover plate makes it easy to put on and take off the cover plate, making it convenient to use.

[0008] In the aforementioned dual-purpose gas fire basin table, multiple evenly distributed ring-shaped reinforcing members are installed on the bottom surface of the tabletop; the reinforcing members can increase the strength of the tabletop and ensure the stability of the structure.

[0009] In the aforementioned dual-purpose gas fire pit table, a baffle is rotatably installed between each pair of adjacent table legs; a bottom support frame is installed between the bottom ends of all the table legs, and a fixing ring seat for fixing the gas cylinder is provided on the bottom support frame; a locking component is threaded on the fixing ring seat; the baffle can hide and protect the gas cylinder; and the setting of the fixing ring seat and the locking component can further fix the position of the gas cylinder, ensuring the stability of the structure.

[0010] Compared with existing technologies, this utility model improves upon existing gas-fired brazier tables by incorporating a tabletop brazier and a first burner on the tabletop, with the first burner connected to a gas cylinder via a first igniter. A combustion channel and a second burner are arranged around the bottom of the tabletop brazier, with the second burner connected to the gas cylinder via a second igniter. This creates two independent combustion systems on the brazier table. The first and second igniters are integrated into a central control panel, allowing for simultaneous or individual use of both burners, thus increasing flexibility. Furthermore, the tabletop brazier and gas channel are used to install the first and second burners respectively, and the tabletop brazier and gas cylinder... The gas channels are installed in an interlocking manner, making the overall structure more compact and taking up less space compared to current single-function brazier tables. At the same time, because the first burner is located on the tabletop and the gas outlet of the first burner is located on the top surface of the first burner, the first burner can be used as a conventional brazier table. The second burner, located under the tabletop and arranged in a ring, can provide heating from all sides under the tabletop, thus achieving the function of a heater. This realizes the integration of the brazier table and the heater on the same table. In addition, when the first burner is not in use, it can be used as a regular table, making the entire brazier table multifunctional.

[0011] Furthermore, this invention also incorporates a pressure-reducing valve installed on the main gas supply pipe. This valve reduces and stabilizes the gas pressure output from the gas tank, ensuring a stable supply of gas at the appropriate pressure to the first and second burners, thus guaranteeing operational stability. By configuring a first safety valve, a first thermocouple, a second safety valve, and a second thermocouple, the first and second thermocouples can respectively detect whether the first and second burners are functioning correctly. (When either the first or second burner is working normally, the corresponding first or second thermocouple will generate a potential difference signal due to temperature rise, which will then be controlled by an external controller to open the corresponding first and second safety valves. If either the first or second burner is not functioning correctly, the first and second thermocouples will...) (Since no potential difference signal is generated, the controller will control the opening and closing of the corresponding first and second safety valves), thereby preventing accidental flameout, gas leakage, or even explosion, ensuring safety during use. A cover plate is installed on the top of the tabletop fire basin, covering the top and allowing the entire tabletop to be used as a normal table when the first burner is not in use. The handle groove on the cover plate facilitates easy removal and placement. Multiple evenly distributed reinforcing members are installed on the bottom of the tabletop, increasing its strength and ensuring structural stability. A baffle plate is used to conceal and protect the gas cylinder. The fixing ring and locking mechanism further secure the gas cylinder, ensuring structural stability. Therefore, this invention not only reduces the floor space required but also offers advantages such as functional versatility, high flexibility, high operational stability, high safety, ease of use, and high structural stability.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0020] Example 1. A dual-purpose gas-fired brazier table, configured as follows: Figures 1 to 6 As shown, the table includes four table legs 1 arranged at the four corners, a tabletop 2 installed between the top ends of the four table legs 1, and a gas cylinder located below the tabletop 2. The tabletop 2 has a mounting groove in the middle, within which is a tabletop fire basin 3 with an open top. A first burner 4 is installed inside the tabletop fire basin 3. A partition 5 is provided between each pair of adjacent table legs 1, and a protective plate 6 is vertically installed on the top surface of each partition 5, located between each pair of adjacent table legs 1. A combustion channel 7, hollow in structure, is located on the top surface of the partition 5 between all the protective plates 6. Multiple evenly distributed through holes are provided on the outer surface of each combustion channel 7, and a second burner 8 is installed inside the combustion channel 7. A main control plate is located directly below the combustion channel 7 between two table legs 1, and a first igniter 10 connected to the first burner 4 is installed on the main control plate. A second igniter 11 connected to the second burner 8 is located on one side of the first igniter 10, and both the second igniter 11 and the first igniter 10 are connected to the gas cylinder.

[0021] The gas cylinder is equipped with a main gas supply pipe 12, and a pressure reducing valve 13 is installed on the main gas supply pipe 12. A first branch pipe, connected to a first igniter 10, is located at one end of the main gas supply pipe 12, and a first safety valve 23 is installed on the first branch pipe. A second branch pipe, connected to a second igniter 11, is located on one side of the first branch pipe, and a second safety valve 14 is installed on the second branch pipe. A first thermocouple 15 is installed on the first burner 4, and the first thermocouple 15 is electrically connected to the first safety valve 23. A second thermocouple 16 is installed on the second burner 8. The thermocouple 16 is electrically connected to the second safety valve 14; a cover plate 17 for covering the opening of the top surface of the tabletop fire basin 3 is installed on the top surface of the tabletop fire basin 3, and a handle groove 18 is provided in the middle of the top surface of the cover plate 17; a plurality of annularly distributed reinforcing members 19 are installed on the bottom surface of the tabletop 2; a baffle 20 is rotatably installed between each two adjacent table legs 1; a bottom support frame is installed between the bottom ends of all the table legs 1, and a fixing ring seat 21 for fixing the gas cylinder is provided on the bottom support frame; a locking member 22 is threaded on the fixing ring seat 21.

[0022] Working principle: When using this application, first place the entire fire pit table on a horizontal surface, then open the baffle 20 and place the gas cylinder on the fixing ring seat 21, and rotate the locking part 22. The locking part 22 cooperates with the inner wall of the fixing ring seat 21 to fix the gas cylinder. When the first burner 4 is needed for tabletop cooking and heating, first remove the cover plate 17 from the top surface of the tabletop fire pit 3 through the handle groove 18, so that the top port of the tabletop fire pit 3 is open. Then connect the pressure reducing valve 13 and the gas cylinder valve, open the gas cylinder valve, and let the gas... The gas can be supplied to the first igniter 10 and the second igniter 11 through the main gas supply pipe 12. Turning on the first igniter 10 allows it to ignite the gas, which is then emitted through multiple gas outlets on the top surface of the first burner 4, creating a flame in the tabletop brazier 3. This allows the user to cook, warm themselves, or perform other tasks on the tabletop brazier 3. When the user needs to warm themselves below the tabletop 2, simply turning on the second igniter 11 activates the second burner 8, igniting the gas and emitting it through multiple gas outlets on the top surface of the first burner 4. The second burner 8 has a gas outlet on its inner side, and the ignited flame burns in the combustion channel 7, thus providing heating from all sides under the entire fire pit table. The protective plate 6 and the through holes on the outer side of the combustion channel 7 ensure stable heat output while preventing users from directly contacting the flame, thus ensuring safety. When the first burner 4 and the second burner 8 are working normally, the first thermocouple 15 and the second thermocouple 16 will also generate corresponding voltage signals due to the increase in temperature, and send them to the controller on the main control board (the controller can be FX2C-20MRD, Cortex-R8, or Cortex-M7, etc.; the first thermocouple 15 and the second thermocouple 16 can be WRP-130, EBA / EBT series, or K-MT-SLE-060, etc.). The controller compares the received voltage signal with the internally set voltage threshold. If it is within the set voltage threshold, the controller will determine that the first burner 4 and the second burner 8 are working normally, and control the first safety valve 23 or the second safety valve 14 to remain open.When the first burner 4 and the second burner 8 malfunction and fail to ignite, but the first igniter 10, the second igniter 11, the first safety valve 23, and the second safety valve 14 remain open, the first thermocouple 15 and the second thermocouple 16 will cool down due to the flame extinguishing. At this time, the voltage signal generated by the first thermocouple 15 and the second thermocouple 16 will decrease or disappear. If the voltage signal received by the controller is not within the set voltage threshold or the controller does not receive a voltage signal, the controller will determine that the first burner 4 and the second burner 8 are malfunctioning. In this case, the controller will control the first safety valve 23 and the second safety valve 14 to close, stopping the gas supply from the gas cylinder to the first igniter 10 and the second igniter 11, preventing gas leaks or explosions, and improving safety.
