[0044] The utility model provides an inner ring fire cover 1 which is used for a gas stove 2.
[0045] See also Figure 1 In one embodiment of the utility model, the inner ring fire cover 1 includes a main body 11 and a cover body 12. The top of the main body 11 has an opening, the side of the main body 11 is provided with an air outlet 111, and the bottom of the main body 11 is provided with an air inlet 112; the cover body 12 covers the opening, and the edge of the cover body 12 is sealed and connected to the edge of the opening.
[0046] Specifically, the main body 11 of the inner ring fire cover 1 is arranged in a cylindrical shape, and a gas mixing chamber 118 is provided inside the main body 11, and an air outlet 111 is provided on the side of the main body 11, and an air inlet 112 is provided at the bottom of the main body 11; the air outlet 111 and the air inlet 112 are both connected to the gas mixing chamber 118, and the external gas enters the gas mixing chamber 118 through the air inlet 112, and the gas and air are mixed in the gas mixing chamber 118 to form a gas-air mixture, and are discharged through the air outlet 111 to ignite the ignition needle 21, thereby helping to provide more precise flame control and air flow regulation. And through the setting of the air inlet 112 and the air outlet 111, the precise control of the flame size and the reasonable air flow design are realized, which promotes the efficient combustion of fuel and reduces energy waste.
[0047] The top of the main body 11 of the inner ring fire cover 1 has an opening, and the cover 12 covers the opening of the main body 11, and the edge of the cover 12 is sealed and connected to the edge of the opening of the main body 11, that is, the top of the inner ring fire cover 1 is sealed. Compared with the top open setting of the inner ring fire cover 1, this solution helps to improve the stability of the flame and the safety of the cooking environment. The main body 11 and the cover 12 are sealed, that is, the main body 11 and the cover 12 are detachably connected, so as to facilitate the processing of the inner ring fire cover 1.
[0048] Because the material of the inner ring fire cover 1 usually needs to have the characteristics of high temperature resistance, corrosion resistance, and non-deformation, so as to adapt to the high temperature environment of the gas stove 2 during the cooking process. Therefore, materials such as copper or cast iron, or ceramic materials are generally used, which leads to a high cost of the inner ring fire cover 1 and a large thickness. Therefore, in the embodiment of the utility model, the material of the inner ring fire cover 1 is stainless steel, so as to ensure the high temperature resistance and corrosion resistance of the inner ring fire cover 1. On the other hand, the cost of the stainless steel material is low, which helps to reduce the cost of the inner ring fire cover 1. On the other hand, the stainless steel material can make a thinner inner ring fire cover 1.
[0049] See also Figures 1 to 3 In the embodiment of the utility model, the thickness of the main body 11 is greater than the thickness of the cover body 12. Specifically, since the main body 11 is provided with an air outlet 111 and an air inlet 112, which are the main positions for flame combustion, the required structural strength is relatively large, and since the main body 11 is cylindrical and has the air outlet 111 and the air inlet 112, it is often formed by casting, while the cover body 12 is generally formed by stamping, so the thickness of the main body 11 is set to be greater than the thickness of the cover body 12, thereby ensuring the overall strength of the inner ring fire cover 1 and facilitating the processing of the inner ring fire cover 1.
[0050] Furthermore, the thickness of the main body 11 is greater than or equal to 1 mm and less than or equal to 1.5 mm;
[0051] The thickness of the cover body 12 is greater than or equal to 0.5 mm and less than or equal to 1 mm.
[0052] Specifically, if the thickness of the main body 11 is less than 1 mm, the thickness of the main body 11 is relatively thin, which is not conducive to the structural strength of the main body 11. If the thickness of the main body 11 is greater than 1.5 mm, the thickness of the main body 11 is relatively thick, which may cause the strength redundancy of the main body 11 and increase the processing cost of the inner ring fire cover 1. Specifically, the thickness of the main body 11 can be 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, and 1.5 mm, etc. If the thickness of the cover body 12 is less than 0.5 mm, the thickness of the cover body 12 is relatively thin, which is not conducive to the structural strength of the cover body 12. If the thickness of the cover body 12 is greater than 1 mm, the thickness of the cover body 12 is relatively thick, which may cause the strength redundancy of the main body 11 and increase the processing cost of the inner ring fire cover 1. Specifically, the thickness of the main body 11 can be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, and 1 mm, etc.
[0053] See also Figures 5 to 7In the embodiment of the utility model, the edge of the cover body 12 is provided with a stopper 127 protruding along the side of the inner ring fire cover 1, and the stopper 127 is used to shield the ignition needle 21 of the gas stove. Specifically, the projection of the stopper 127 along the axial direction of the inner ring fire cover 1 covers the ignition needle 21, so that the ignition needle 21 can be guided to ignite, and the ignition needle 21 can be shielded and protected, reducing the possibility of food residues or cooking overflow liquid dripping on the ignition needle 21, and further improving the safety of the gas stove 22.
[0054] In order to ensure the sealed connection between the main body 11 and the cover body 12, in an embodiment of the utility model, a first sealing edge 113 is provided at the outer periphery of the opening, and the first sealing edge 113 extends in a direction away from the opening. The edge of the cover body 12 includes a second sealing edge 121, and the second sealing edge 121 abuts against the first sealing edge 113. A portion of the first sealing edge 113 extends in a direction away from the opening to form a stopper 127. Specifically, the first sealing edge 113 is arranged around the outer periphery of the opening, and the first sealing edge 113 extends in a direction away from the opening. On the one hand, the first sealing edge 113 forms a first sealing surface toward one side of the cover body 12, and the edge of the cover body 12 forms a second sealing edge 121, and the second sealing edge 121 forms a second sealing surface toward one side of the first sealing edge 113. The first sealing surface and the second sealing surface abut against each other, thereby forming a surface seal at the periphery of the opening to ensure a sealing effect. On the other hand, the first sealing edge 113 and the second sealing edge 121 form a cover edge. The cover edge structure can block the air outlet 111. During the cooking process, if there is too much liquid in the pot or the liquid boils too violently, the liquid may overflow. The cover edge structure can prevent moisture and grease in the food from sliding into the air outlet 111 and then entering the inner ring fire cover 1, thereby improving the safety of the inner ring fire cover 1 and facilitating the cleaning of the inner ring fire cover 1. A portion of the first sealing edge 113 extends away from the opening to form a blocking portion 127, that is, the blocking portion 127 is integrally formed with the first sealing edge 113 to ensure the fixing stability of the blocking portion 127.
[0055] Furthermore, the first sealing edge 113 is bent and connected to a connecting edge 122 and a sealing pressing edge 123 except for the stopper 127. The side of the connecting edge 122 away from the first sealing edge 113 is connected to the sealing pressing edge 123, and the sealing pressing edge 123 abuts against the side of the first sealing edge 113 away from the cover body 12 to press the first sealing edge 113 against the second sealing edge 121. Specifically, one side of the connecting edge 122 is bent and connected to the outer side of the second sealing edge 121, and the other side is bent and connected to the sealing pressing edge 123, so that the connecting edge 122 is roughly parallel to the axial direction of the inner ring fire cover 1, the sealing pressing edge 123 is roughly parallel to the first sealing edge 113 and / or the second sealing edge 121, and the sealing pressing edge 123 abuts against the side of the first sealing edge 113 away from the cover body 12 to press the first sealing edge 113 against the second sealing edge 121. That is, the cover body 12 and the main body 11 are fixed by riveting, so that the sealing effect can be ensured and the installation of the two can be facilitated. Since the cover body 12 needs to form a multi-section bent structure, a thinner cover body 12 is provided, which can also facilitate the processing of the cover body 12. In addition, the first sealing edge 113 is bent and connected with a connecting edge 122 and a sealing pressing edge 123 except for the stopper 127, that is, the edge of the cover body 12 connected to the outer side of the first sealing edge 113 is divided into two parts, one part extends roughly parallel to the horizontal direction to form the stopper 127, and the other part is stamped to form the connecting edge 122 and the sealing pressing edge 123, so that the stopper 127, the connecting edge 122 and the sealing pressing edge 123 can be ensured to be fixed and stable, and the processing of the cover body 12 can be facilitated.
[0056] In other embodiments, see Figures 1 to 4 The edge of the cover body 12 may also not be provided with the stopper 127. In this case, the outer periphery of the first sealing edge 113 is provided with a connecting edge 122 and a sealing pressing edge 123, and the connecting edge 122 and the sealing pressing edge 123 are jointly covered on the outer periphery of the first sealing edge 113.
[0057] Among them, the first sealing edge 113 is integrally formed with the main body 11, that is, the first sealing edge 113 is configured as a flange structure arranged on the edge of the opening, so as to facilitate the installation of the first sealing edge 113 and ensure the fixation of the first sealing edge 113; the second sealing edge 121, the connecting edge 122 and the sealing pressure edge 123 are all integrally formed on the cover body 12, that is, the second sealing edge 121, the connecting edge 122 and the sealing pressure edge 123 are formed by flanging in sequence through the edge of the cover body 12, so as to facilitate the installation of the second sealing edge 121, the connecting edge 122 and the sealing pressure edge 123 and ensure the fixation of the second sealing edge 121, the connecting edge 122 and the sealing pressure edge 123.
[0058] Of course, in other embodiments, the cover 12 and the main body 11 may also be fixed by welding, such as by laser welding.
[0059] For further information, see Figures 1 to 7 , the side of the sealing edge 123 away from the connecting edge 122 is spaced apart from the side of the main body 11. Specifically, the side of the sealing edge 123 away from the connecting edge 122 is spaced apart from the side of the main body 11, that is, the sealing edge 123 does not completely cover the side of the first sealing edge 113 away from the cover body 12, which, on the one hand, facilitates the first sealing edge 113 to be inserted between the second sealing edge 121 and the sealing edge 123, thereby facilitating the installation of the cover body 12 and the main body 11; on the other hand, it reduces the possibility that the liquid or grease flowing to the edge of the second sealing edge 121 flows along the sealing edge 123 to the side wall of the main body 11, and flows from the air outlet 111 to the inside of the main body 11.
[0060] In the embodiment of the utility model, a liquid receiving groove 125 is provided on one side of the cover body 12 away from the main body 11. The liquid receiving groove 125 is used to receive liquid that may overflow during cooking, thereby facilitating the cleaning of the gas stove 2 and improving the safety of the inner ring fire cover 1.
[0061] Furthermore, part of the cover 12 is recessed toward the main body 11 to form a liquid receiving groove 125. That is, the liquid receiving groove 125 is integrally formed on the cover 12 and formed by the cover 12 through a stamping process, thereby facilitating the processing of the liquid receiving groove 125.
[0062] Furthermore, a reinforcement groove 126 is provided on the bottom wall of the liquid receiving tank 125. Since the overall thickness of the cover body 12 is relatively thin, in order to further improve the structural strength of the liquid receiving tank 125 and reduce the possibility of deformation of the cover body 12, a reinforcement groove 126 is provided on the bottom wall of the liquid receiving tank 125, thereby further improving the structural strength of the liquid receiving tank 125. In this embodiment, the reinforcement groove 126 is provided in the middle of the bottom wall of the liquid receiving tank 125, and is formed by being recessed in the direction close to the main body 11 through the bottom wall, thereby facilitating the processing of the reinforcement groove 126. In other embodiments, the bottom wall of the liquid receiving tank 125 may also be provided with reinforcement ribs, or configured as a wave-shaped reinforcement structure.
[0063] In order to facilitate the liquid to flow smoothly into the liquid receiving groove 125, in the embodiment of the utility model, a guide slope 124 is formed on the side of the second sealing edge 121 away from the first sealing edge 113, and the height of the guide slope 124 is set to decrease in the direction close to the middle of the cover body 12. Specifically, the guide slope 124 can conveniently guide the liquid that may overflow during the cooking process, which not only facilitates the overflowed liquid to flow into the liquid receiving groove 125, but also reduces the possibility of the overflowed liquid dripping. And the guide slope 124 is formed on the side of the second sealing edge 121 away from the first sealing edge 113, wherein the first sealing edge 113 and the second sealing edge 121 can be bent upward relative to the horizontal direction, and the bending angle is generally less than or equal to 45°.
[0064] See also Figure 4The inner ring fire cover 1 is generally fixedly installed on the gas distribution plate 22, and is often arranged on the inner ring of the gas distribution plate 22. The outer ring fire cover 23 is fixed to the outer ring of the gas distribution plate 22. To adapt to the structure of the gas distribution plate 22, in an embodiment of the utility model, a mounting portion 115 is provided in the air inlet hole 112, and a first mounting hole 116 is opened in the mounting portion 115. The first fastener passes through the first mounting hole 116 and is fastened to the gas distribution plate 22 of the gas stove 2. Specifically, that is, when the mounting portion 115 of the gas distribution plate 22 is arranged in its inner circle, the mounting portion 115 on the inner ring fire cover 1 is also correspondingly arranged in the air inlet hole 112, that is, the mounting portion 115 is connected to the inner periphery of the air inlet hole 112 and extends toward the center of the air inlet hole 112, and in order to improve the installation stability of the mounting portion 115, in one embodiment, the mounting portion 115 extends radially along the air inlet hole 112, and both ends thereof are connected to the inner periphery of the air inlet hole 112, and the mounting hole 116 is correspondingly arranged in the middle of the mounting portion 115, thereby ensuring the fixed stability of the inner ring fire cover 1.
[0065] Furthermore, the inner periphery of the air inlet hole 112 is formed with a positioning flange 114 extending into the main body 11, and the mounting portion 115 is provided on the positioning flange 114. Specifically, in order to further position the gas distribution plate 22 or the gas distribution pipe for installation, the inner periphery of the air inlet hole 112 is formed with a positioning flange 114 extending into the main body 11, so that the inner ring of the gas distribution plate 22 or the gas distribution pipe is plugged into the inner periphery of the positioning flange 114, thereby positioning the gas distribution plate 22 or the gas distribution pipe, and facilitating the installation of the inner ring fire cover 1.
[0066] See also Figures 8 to 10 In another embodiment of the utility model, the main body 11 is provided with a second mounting hole 119 on the outer periphery of the air inlet hole 112, and the second fastener passes through the second mounting hole 119 to be fastened to the gas distribution plate 22 of the gas stove 22. Specifically, when the mounting portion of the gas distribution plate 22 is arranged outside its inner circle, the mounting portion on the inner ring fire cover 1 is also correspondingly arranged outside the air inlet hole 112, that is, the second mounting hole 119 is opened in the part of the main body 11 located outside the air inlet hole 112, and the second fastener passes through the second mounting hole 119 to be fastened to the gas distribution plate 22 of the gas stove. In order to improve the installation stability of the inner ring fire cover 1, the second mounting hole 119 is provided in plurality, and the plurality of second mounting holes 119 are arranged at intervals along the circumference of the air inlet hole 112.
[0067] To further provide more precise flame control and air flow regulation, in the embodiments of the present invention, please refer to Figures 1 to 7There are multiple air outlet holes 111, and the multiple air outlet holes 111 are arranged at intervals along the circumference of the main body 11, and the multiple air outlet holes 111 are arranged in two rows along the axial direction of the main body 11, and the air outlet holes 111 in the two rows are staggered. Specifically, the multiple air outlet holes 111 include multiple first air outlet holes 111 and multiple second air outlet holes 111, and the multiple first air outlet holes 111 and the multiple second air outlet holes 111 are arranged at intervals along the circumference of the main body 11, and the multiple first air outlet holes 111 and the multiple second air outlet holes 111 form two rows arranged at intervals along the axial direction of the main body 11, thereby increasing the number of air outlet holes 111, helping the gas to be evenly released from the surface of the fire cover to form an evenly distributed flame, thereby improving cooking efficiency and thermal efficiency, and the two rows of air outlet holes 111 are staggered, that is, the multiple first air outlet holes 111 and the multiple second air outlet holes 111 are staggered. By reasonably distributing the air outlet holes 111, the mixing ratio of gas and air can also be optimized to achieve more complete combustion, reduce harmful gas emissions, and further adjust the gas flow rate passing through, thereby adjusting the size of the firepower to meet different cooking needs, and can also reduce the backfire phenomenon, that is, the flame enters the burner, thereby improving the safety of the gas stove 2.
[0068] In other embodiments, more than two rows of air outlet holes 111 may be provided, such as three rows or four rows of air outlet holes 111 , or only one row of air outlet holes 111 may be provided.
[0069] Furthermore, the axial direction of the air outlet hole 111 is tilted upward relative to the horizontal direction, so as to further adjust the air outlet direction of the air outlet hole 111, improve the stability of the flame, and adjust the air flow direction to improve the flame stabilization effect and combustion effect of the inner ring fire grate.
[0070] In order to further improve the flame stabilization effect of the inner ring fire grate, in an embodiment of the utility model, a flame stabilization hole 117 is provided below the outlet hole 111, and a plurality of flame stabilization holes 117 are arranged at intervals along the circumference of the main body 11, and the inner diameter of the flame stabilization hole 117 is smaller than the inner diameter of the outlet hole 111. Specifically, the flame stabilization holes 117 are arranged at intervals along the circumference of the main body 11, which helps to stabilize the flame, reduce the phenomenon of flame separation (flame detaching from the burner) and flameout (flame completely extinguished), and enhance the stability of combustion. In addition, the flame stabilization hole 117 can serve as a channel for mixing gas and air, helping to improve the mixing ratio and achieve more efficient combustion. The flame stabilization hole 117 is arranged below the outlet hole 111, because after the gas is ejected from the outlet hole 111, a stable flame zone will be formed above the flame stabilization hole 117, so the flame stabilization hole 117 is arranged below the outlet hole 111, which helps to form a stable flame foundation. Furthermore, the inner diameter of the flame stabilizing hole 117 is smaller than the inner diameter of the air outlet hole 111, which helps to concentrate the flame and facilitates accurate control of the cooking temperature.
