DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the present invention, and thus to more clearly define the scope of protection claimed by the present invention, the present invention is described in detail below with respect to certain specific embodiments of the present invention. It should be noted that the following are only certain specific implementation methods of the present invention, which are only part of the embodiments of the present invention, wherein the specific and direct description of the relevant structures is only for the convenience of understanding the present invention, and each specific feature does not naturally and directly limit the scope of implementation of the present invention. The conventional selections and substitutions made by those skilled in the art under the guidance of the present invention shall be deemed to be within the scope of protection claimed by the present invention.

[0033] Embodiment 1:

[0034] like Figure 1-Figure 3 , Figure 5-Figure 8 As shown, the utility model discloses an infrared combustion gas oven, comprising:

[0035] A furnace frame 1, a furnace cavity 11 is arranged in the furnace frame 1, and a barbecue area 12 is arranged above the furnace cavity 11;

[0036] Burner 2, the number of burners 2 is 4, each burner 2 is arranged in the furnace cavity 11 at intervals along the left-right direction, specifically, each burner 2 includes a gas supply pipe 21 extending front and rear, a combustion pipe 22 extending front and rear, and a connecting pipe 23 extending left and right, the number of combustion pipes 22 is two, and the two combustion pipes 22 corresponding to each burner 2 are arranged at intervals left and right, and the connecting pipe 23 is used to connect the corresponding gas supply pipe 21 and the corresponding combustion pipes 22, in addition, a plurality of first fire outlets 221 are arranged at intervals along the front-back direction on the upper side of each combustion pipe 22, so that after the burner 2 is connected to the gas system, the gas system supplies gas to the gas supply pipe 21, the gas enters the combustion pipe 22 through the connecting pipe 23, and is ejected from the first fire outlet 221, so that igniting the first fire outlet 221 will produce a burning flame;

[0037] The ignition plates 3 are made of stainless steel. The number of the ignition plates 3 is arranged corresponding to the number of the combustion tubes 22 , and each ignition plate 3 is located above the corresponding combustion tube 22 .

[0038] The flame generated by the combustion of each first fire outlet 221 burns upward and directly burns the corresponding ignition plate 3 to heat the corresponding ignition plate 3 to turn red and have an infrared heating effect. The heated red ignition plates 3 heat the furnace cavity 11 through a large area of ​​infrared heat radiation.

[0039] Therefore, 1. The heat generated by the combustion of gas is not directly diffused into the air of the furnace cavity 11 in the traditional way, but is mainly transferred to the ignition plate 3, so that the ignition plate 3 with excellent thermal conductivity absorbs the heat of the flame in a multi-point manner, and diffuses it outward in a surface manner, so that the large-area heat diffusion will heat the furnace cavity 11 more evenly, making the temperature in the furnace cavity 11 more uniform, and grilling food in the grilling area 12 above the furnace cavity 11 with uniform temperature can make the food heated more evenly to improve the grilling quality; 2. Each burner 2 is provided with two combustion tubes 22, so that each burner 2 can be used in combination with two ignition plates 3 to increase the infrared heat radiation area, so as to achieve more uniform heating of each space in the furnace cavity 11.

[0040] The number of burners 2 can be increased or decreased according to actual conditions to achieve a reasonable configuration.

[0041] In other embodiments, the number of combustion tubes 22 corresponding to each burner 2 is 3-5.

[0042] Preferably, each ignition plate 3 in the present embodiment is provided with a U-shaped or V-shaped temperature gathering chamber 31, and the temperature gathering chamber 31 is open downward; in addition, each first fire outlet 221 is located below the corresponding temperature gathering chamber 31, and each first fire outlet 221 corresponds to the temperature gathering chamber 31 upward, and the distance between each first fire outlet 221 and the opening below the temperature gathering chamber 31 is s, s≤5cm, and 1cm is adopted in the present embodiment.

[0043] Therefore, the first fire outlet 221 is located below the temperature gathering chamber 31 and close to the temperature gathering chamber 31, so that the first fire outlet 221 is directly connected to the furnace chamber 11, so that the furnace chamber 11 can better supply oxygen to the first fire outlet 221 for combustion to improve the combustion efficiency, and because the flame close to the first fire outlet 221 is mainly the inner flame with a lower temperature, the heat diffused from the inner flame into the furnace chamber 11 is less, and the outer flame away from the first fire outlet 221 enters the temperature gathering chamber 31 to lock the heat energy in the temperature gathering chamber 31 to heat the ignition plate 3, so that the infrared heat radiation efficiency of the ignition plate 3 is higher.

[0044] In other embodiments, the ignition plate 3 is provided as a flat plate parallel to the horizontal direction.

[0045] In addition, each combustion tube 22 in the present embodiment is provided with two connecting baffles 222 arranged at intervals along the front-to-back direction, and each connecting baffle 222 faces upward and is inserted into the corresponding temperature collection chamber 31; correspondingly, each ignition plate 3 is provided with a supporting abutment 32, and each supporting abutment 32 and the corresponding connecting baffle 222 abut against each other so that each connecting baffle 222 supports the corresponding ignition plate 3.

[0046] Therefore, 1. The ignition plate 3 is fixedly installed on the combustion tube 22 by connecting the baffle plate 22 and the supporting portion 32, which not only improves the installation stability of the ignition plate 3 relative to the combustion tube 22, but also makes the alignment of the ignition plate 3 and the combustion tube 22 more precise, so that the overall heating of the ignition plate 3 is more uniform and the infrared heat radiation heats the furnace cavity 11 more uniformly; 2. Multiple connecting baffles 222 are matched with the ignition plate 3 to further improve the stability of the matching, prevent the ignition plate 3 from tilting forward and backward relative to the combustion tube 22, resulting in uneven heating of the ignition plate 3 front and back, thereby affecting the temperature uniformity in the furnace cavity 11.

[0047] In other embodiments, the number of connecting baffles 222 on each combustion tube 22 may be 3-5, so that more positions of the connecting baffles 222 can be matched with the ignition plate 3 to improve the installation stability of the ignition plate 3.

[0048] The support portion 32 and the connecting baffle 222 may be connected by welding, bolting, riveting, etc.

[0049] In order to facilitate the disassembly of the ignition plate 3 in this embodiment, the ignition plate 3 and the connecting baffle 222 are directly vertically plugged in and fixed in an interference fit.

[0050] Preferably, the two connecting baffles 222 corresponding to each combustion tube 22 in this embodiment are arranged at both ends of the length of the corresponding combustion tube 22 and are formed on the combustion tube 22 in a bending manner so that each first fire outlet 221 is located between the corresponding two connecting baffles 222.

[0051] Therefore, the connecting baffle 222 can not only cooperate with the supporting abutment 32 to realize the connection between the ignition plate 3 and the combustion tube 22, but also the connecting baffle 222 can be plugged into and cooperated with the temperature gathering chamber 31 to seal the front and rear sides of the temperature gathering chamber 31 to a certain extent, thereby preventing excessive heat in the temperature gathering chamber 31 from directly flowing out from the front and rear sides of the ignition plate 3 and causing the temperature of the front and rear sides of the furnace cavity 11 to be too high, resulting in uneven temperature in the furnace cavity 11. Moreover, since the main baking position of the barbecue area 12 is the front and rear middle part, the temperature on both sides is too high to effectively bake the food, and may even cause the operator to be scalded by the heat flow.

[0052] Preferably, each ignition plate 3 in this embodiment is located on the left and right sides of the corresponding temperature collection chamber 31 and is respectively provided with an inclined heat radiation plate 33, and the angle between each heat radiation plate 33 and the horizontal plane is α, 70°≤α<90°, and 80° is adopted in this embodiment. Therefore, compared with the vertical and horizontal situations, the inclined heat radiation plate 33 can not only increase the heat radiation area to further optimize the heating uniformity of the furnace chamber 11, but also the angle between the heat radiation plate 33 and the horizontal plane is larger, so that the heat diffusion energy of the heat radiation plate 33 is distributed in a larger vertical range, realizing the integration of energy after the heat energy rises and improving the heat uniformity in the furnace chamber 11.

[0053] Preferably, the number of supporting abutments 32 corresponding to each ignition plate 3 in the present embodiment is two to correspond to the number of corresponding heat radiation plates 33, and each supporting abutment 32 is respectively bent and arranged at the lower end of the corresponding heat radiation plate 33, and the two supporting abutments 32 corresponding to each ignition plate 3 are extended in a horizontal direction approaching each other and are inclined upward, and correspondingly, each connecting baffle 222 is respectively provided with an abutting surface 2221 corresponding to the corresponding two supporting abutments 32, and the two abutting surfaces 2221 corresponding to each connecting baffle 222 extend in a horizontal direction approaching each other and are inclined upward.

[0054] Therefore, 1. The support butt portion 32 bent and arranged below the heat radiation plate 33 makes the structure of the ignition plate 3 simpler, and the processing is convenient, thereby reducing the production cost of the ignition plate 3; 2. The upwardly inclined support butt portion 32 and the abutment surface 2221 not only have a guiding function to make the assembly more convenient when the baffle plate 222 is connected to the ignition plate 3, but also can tighten the distance between the support butt portions 32 to ensure stable abutment.

[0055] Among them, each connecting tube 23 in this embodiment is located between the corresponding two combustion tubes 22, and the two ends of the length of each connecting tube 23 connect the middle of the length of the corresponding two combustion tubes 22, so that the combustion tube 22 and the connecting tube 23 are combined to form an H shape.

[0056] In other embodiments, the connecting tube 23 is connected to the front end or rear end of the combustion tube 22 so that the combustion tube 22 and the connecting tube 23 are combined to form a U shape, or even the connecting tube 23 is inclined so that the combustion tube 22 and the connecting tube 23 are combined to form an N shape.

[0057] Combination Figure 4 , Fig.10 As shown, each connecting pipe 23 in this embodiment is provided with a second fire outlet 231; correspondingly, a cover 4 is placed on top of each connecting pipe 23. The flame generated by the combustion of each second fire outlet 231 burns upward and directly burns the corresponding cover 4 to heat the corresponding cover 4 red, and the heated red cover 4 heats the furnace cavity 11 through infrared heat radiation.

[0058] Therefore, by opening the second fire outlet 231 on the connecting pipe 23, the covering member 4 is heated, and the furnace cavity 11 can be heated more evenly in the left and right directions through the heat radiation of the covering member 4. The covering member 4 is located in the middle of the front and back of the furnace cavity 11, and its heat diffusion can cover the front and back directions more evenly, so that the front and back temperatures in the furnace cavity 11 are more uniform.

[0060] Specifically, the rear end of each air supply pipe 21 in the present embodiment is connected to the middle of the length of the corresponding connecting pipe 23; wherein each covering member 4 includes a first positioning plate 43 at the top, a second positioning plate 44 at the front, and a third positioning plate 45 at the rear, and the covering member 4 is formed by bending to form a second positioning plate 44, a first positioning plate 43, and a third positioning plate 45 connected in sequence, wherein each first positioning plate 43 is horizontally arranged, and each ignition plate 3 is located directly above the corresponding first positioning plate 43, and the two can be in contact with each other, or separated by a small spacing, so as to The ignition plate 3 is used to limit the first positioning plate 43 at the top to restrict the corresponding covering member 4 from flipping over and moving upward, wherein the lower end of each second positioning plate 44 is provided with a positioning groove 441 adapted to the outer peripheral shape of the corresponding air supply pipe 21, and each air supply pipe 21 is matched in the corresponding positioning groove 441 to realize the positioning of the covering member 4 in the left and right directions relative to the connecting pipe 23, wherein the lower end of each third positioning plate 45 is abutted against the outer peripheral wall of the corresponding connecting pipe 23 to realize the positioning of the covering member 4 in the front and rear directions relative to the connecting pipe 23, and the combination can realize the stable positioning of the covering member 4.

[0061] The cover member 4 can be directly placed on the connecting pipe 23 to facilitate assembly and disassembly, or the third positioning plate 45 can be welded to the connecting pipe 23 to improve the connection strength.

[0062] It should be noted that the ignition plate 3 also has the function of covering the combustion tube 22 above the combustion tube 22 to prevent the falling garbage from falling on the combustion tube 22 and causing the blockage of the first fire outlet 221. Similarly, the covering member 4 also has the function of covering the connecting tube 23 above the connecting tube 23 to prevent the falling garbage from falling on the connecting tube 23 and causing the blockage of the second fire outlet 231.
