Description

Technical Field

[0001] The present application relates to the technical field of gas stoves, and in particular to an energy gathering plate and a gas stove. Background Art

[0002] The burner of a gas stove emits a large amount of heat in all directions when burning. The relevant technology sets an energy-gathering disk, which surrounds the burner to gather heat to improve thermal efficiency. Since the single-layer energy-gathering disk has a poor thermal insulation effect, some heat from the upper surface of the energy-gathering disk is still transferred to the lower surface during the combustion process of the burner, resulting in heat loss. Therefore, the energy-gathering disk is designed to have a double-layer structure to improve the thermal insulation effect.

[0003] A double-layer energy-gathering disk is generally composed of an upper and lower disk body, which are connected to each other to form a relatively closed cavity. Since the thermal conductivity of the air in the cavity is low, this can reduce the heat conduction between the upper and lower disk bodies. However, since the upper and lower disk bodies are still connected with a large contact area, there is still a lot of heat transferred from the upper disk body to the lower disk body.

[0045] The first aspect of the present application discloses an energy collecting disk, which is applied to a gas device provided with a burner 5000. The gas device may be a gas stove, or a combination of a gas stove and other electrical appliances, or other equipment in which the burner 5000 is applied. The energy collecting disk will be described in detail below using the gas stove as an example.

[0046] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, in some embodiments of the present application, the energy concentrating disk includes an upper disk body 1000 and a lower disk body 2000, wherein the upper disk body 1000 includes a first outer ring portion 1100 and a first inner ring portion 1200, and the lower disk body 2000 includes a second outer ring portion 2100 and a second inner ring portion 2200, and the first outer ring portion 1100 is connected to the second outer ring portion 2100, so that a cavity 3100 is formed between the upper disk body 1000 and the lower disk body 2000, and the first inner ring portion 1200 and the second inner ring portion 2200 are alternately arranged, so that a first gap 3200 is formed between the first inner ring portion 1200 and the second inner ring portion 2200, and the first gap 3200 is connected to the cavity 3100. The connection between the upper disk body 1000 and the lower disk body 2000 is achieved by connecting the first outer ring portion 1100 and the second outer ring portion 2100, and the first inner ring portion 1200 and the second inner ring portion 2200 are alternately arranged to form a non-contact structure, thereby reducing the contact area between the upper disk body 1000 and the lower disk body 2000, which is beneficial to reducing the heat transferred from the upper disk body 1000 to the lower disk body 2000, and the first gap 3200 formed by the alternate arrangement of the first inner ring portion 1200 and the second inner ring portion 2200 can cause a small flow of air in the cavity 3100, further reducing the heat transferred from the upper disk body 1000 to the lower disk body 2000, thereby effectively improving the thermal efficiency.

[0047] Specifically, the energy collecting disk is a structure that can gather heat to prevent the heat from being lost too quickly, and needs to be used in conjunction with the burner 5000. The burner 5000 is a structure that allows gas to flow into it and out of it, so that the gas is ignited to form a flame. For example, the burner 5000 includes a burner head and an ejector pipe, which is connected to the burner head. The ejector pipe is used to cooperate with the gas supply mechanism to eject gas toward the burner head, and at the same time eject a certain amount of air to mix with the gas to form a mixed gas and transport it to the burner head. The mixed gas then flows out of the burner head and is ignited by the ignition needle.

[0048] Generally speaking, the gas supply mechanism includes a nozzle, which receives gas from pipeline natural gas or bottled liquefied gas. The nozzle corresponds to the air inlet of the ejector tube. The nozzle sprays the gas into the ejector tube, and at the same time drives the outside air (primary air) into the ejector tube through the air inlet of the ejector tube, so that the gas and air are initially mixed in the ejector tube. The ejector tube ejects the mixed gas to the burner head. The burner head has a larger space than the ejector tube, which can make the gas and air further mixed evenly, which is conducive to the full combustion of the gas. A fire cover structure is generally provided on the burner head. The fire cover structure has a fire outlet hole, which is connected to the inside of the burner head. The mixed gas formed by the gas and air is ejected from the fire outlet hole and then ignited by the discharge of the nearby ignition needle to form a flame. It can be understood that the structure of the burner 5000 is not limited to the above example.

[0049] When the burner 5000 is burning, the heat generated by the burner 5000 will dissipate in all directions. In order to prevent the heat from being lost too quickly, an energy collecting disk is provided. The energy collecting disk surrounds the burner 5000. In this way, the heat generated by the burner 5000 is gathered, thereby preventing the heat from being lost too quickly. In some technologies, the energy collecting disk is a single-layer structure. Since the energy collecting disk cannot be made heat-insulating for the time being, the heat generated by the burner 5000 will be transferred from the upper surface of the single-layer energy collecting disk to the lower surface, thereby causing heat loss. For this reason, in the related technology, the problem is solved by designing the energy collecting disk into a double-layer or multi-layer structure.

[0050] Taking the energy-gathering disk as a double-layer structure as an example, in the related technology, the energy-gathering disk includes an upper disk body 1000 and a lower disk body 2000. The upper disk body 1000 and the lower disk body 2000 need to be connected to each other to form a cavity 3100. There are many ways to connect the upper disk body 1000 and the lower disk body 2000, such as welding, crimping or riveting to achieve mutual connection, so that a relatively closed cavity 3100 is formed between the upper disk body 1000 and the lower disk body 2000. The thermal conductivity of the air in the cavity 3100 is low, which can reduce the heat conduction from the upper disk body 1000 to the lower disk body 2000, thereby improving the thermal efficiency of combustion.

[0051] In the related art, the inner circle of the upper plate body 1000 needs to be connected to the inner circle of the lower plate body 2000, and the outer circle of the upper plate body 1000 needs to be connected to the outer circle of the lower plate body 2000. In this way, a larger contact area is formed between the inner circle of the upper plate body 1000 and the inner circle of the lower plate body 2000, as well as between the outer circle of the upper plate body 1000 and the outer circle of the lower plate body 2000, so heat is easily transferred from the upper plate body 1000 to the lower plate body 2000. It can be understood that the upper plate body 1000 is closer to the flame than the lower plate body 2000, so the upper plate body 1000 has higher heat than the lower plate body 2000. If a large amount of heat is transferred from the upper plate body 1000 to the lower plate body 2000, this will accelerate the heat loss of the upper plate body 1000 (large heat loss), and this part of the lost heat will no longer heat the heated object (such as pots, etc.), which will reduce the thermal efficiency. To this end, in this embodiment, the problem is solved by optimizing the connection structure between the upper plate body 1000 and the lower plate body 2000.

[0052] The upper plate body 1000 has a first outer ring portion 1100 located on the outside and a first inner ring portion 1200 located on the inside, and the lower plate body 2000 has a second outer ring portion 2100 located on the outside and a second inner ring portion 2200 located on the inside, the first outer ring portion 1100 corresponds to the second outer ring portion 2100 and is connected and fixed to each other, and the first inner ring portion 1200 corresponds to the second inner ring portion 2200 and is arranged at intervals. The connection between the first outer ring portion 1100 and the second outer ring portion 2100 is realized in this way, for example, the connection between the first outer ring portion 1100 and the second inner ring portion 2200 is realized by welding and fixing (welding along the circumferential direction). It is understandable that when the heated object is placed on the energy-gathering disk, the contact point between the heated object and the energy-gathering disk is closer to the outer side of the upper disk body 1000 and the outer side of the lower disk body 2000. Therefore, by connecting the first outer ring part 1100 and the second outer ring part 2100 together, the heated object can be better supported to prevent the connection between the upper disk body 1000 and the lower disk body 2000 from being disconnected. In addition, since the first inner ring part 1200 and the second inner ring part 2200 are arranged alternately, in order to prevent the first gap 3200 formed by the first inner ring part 1200 and the second inner ring part 2200 from being compressed when the heated object is placed on the energy-gathering disk, the first inner ring part 1200 and the second inner ring part 2200 need to have a high structural strength. For example, the first inner ring part 1200 and the second inner ring part 2200 are both prepared by integrated molding, and the material can be stainless steel. Since the energy focusing disk needs to surround the burner 5000 , the first gap 3200 is also in a ring shape surrounding the burner 5000 .

[0053] It is precisely by designing the first inner ring portion 1200 and the second inner ring portion 2200 to be non-contact that the contact area between the upper plate body 1000 and the lower plate body 2000 is reduced, and the heat transferred from the upper plate body 1000 to the lower plate body 2000 can be reduced, and the heat loss can be reduced. In addition, the first gap 3200 formed by the first inner ring portion 1200 and the second inner ring portion 2200 is connected to the cavity 3100. During the heating process of the energy-gathering plate, the air in the cavity 3100 can flow slightly through the setting of the first gap 3200, avoiding the increase of the thermal conductivity of the air in the cavity 3100 during the heating process, thereby further reducing the heat transferred from the upper plate body 1000 to the lower plate body 2000, achieving efficient heating of the heated object and improving the heating efficiency.

[0054] Combine 4 and Figure 5 As shown, in some embodiments of the present application, the end face of one of the first outer ring portion 1100 and the second outer ring portion 2100 is connected to the other of the first outer ring portion 1100 and the second outer ring portion 2100, thereby reducing the contact area between the first outer ring portion 1100 and the second outer ring portion 2100, thereby reducing the heat transferred through the contact between the first outer ring portion 1100 and the second outer ring portion 2100.

[0055] The end face of the first outer ring 1100 may be connected to the inner surface of the second outer ring 2100, or the end face of the second outer ring 2100 may be connected to the lower surface of the first outer ring 1100. The connection method may be welding. The welding method effectively realizes the connection and fixation of the end face with other parts, has high connection strength, and is relatively convenient to operate. Taking the case where the end face of the second outer ring 2100 is welded to the lower surface of the first outer ring 1100 as an example, the end face of the second outer ring 2100 is positioned to the lower surface of the first outer ring 1100, and then the two are connected to each other by welding, so that the contact area between the first outer ring 1100 and the second outer ring 2100 after connection is minimized, so that the contact area between the first outer ring 1100 and the second outer ring 2100 can be minimized, thereby reducing the heat transfer.

[0056] Combination Figure 4 , Figure 6 and Figure 7 As shown, in some embodiments of the present application, at least a portion of the first inner ring portion 1200 extends downwardly to cover the top of the second inner ring portion 2200, so that the first gap 3200 formed between the first inner ring portion 1200 and the second inner ring portion 2200 is open downwardly, thereby preventing liquid or other debris from entering the cavity 3100 through the first gap 3200.

[0057] Specifically, since the first inner ring portion 1200 is located inside the upper plate body 1000 and the second inner ring portion 2200 is located inside the lower plate body 2000, when at least part of the first inner ring portion 1200 extends downward to cover the top of the second inner ring portion 2200, the first gap 3200 formed between the first inner ring portion 1200 and the second inner ring portion 2200 is open downward. The environment of the energy-gathering disk is relatively complex, and there is a possibility of liquid splashing or other debris. In this embodiment, the first gap 3200 is opened downward, so in the top-down direction, liquid or other debris moving downward under the action of gravity will be blocked by the first inner ring portion 1200 and cannot enter the cavity 3100 through the first gap 3200, thereby preventing liquid or other debris from entering the cavity 3100 and affecting the heat insulation effect of the cavity. It can be understood that at least part of the first inner circle portion 1200 extends downward, which may be directly downward or obliquely downward. The so-called front, back, left, right, up and down directions are based on the installation of the energy concentrating plate in the kitchen. The side of the energy concentrating plate facing the user is the front, the side away from the user is the back, the side corresponding to the user's left hand is the left, the side corresponding to the user's right hand is the right, the side close to the ground is the bottom, and the side away from the ground is the top.

[0058] Combination Figure 6 and Figure 7 As shown, in some embodiments of the present application, the size of the first gap 3200 along the vertical direction (up and down direction) is d1, and d1 needs to meet the requirement of not less than 0.1mm and not more than 3mm, for example, d1 is 0.1mm, 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm or 3mm. Specifically, the existence of the first gap 3200 forms an air layer, and the thickness (d1) of the air layer cannot be too large, so that the air in the cavity 3100 can be ensured to flow slightly on the premise of ensuring the separation of the first inner ring portion 1200 and the second inner ring portion 2200, and d1 cannot be too large. When d1 is too large, the air in the cavity 3100 will flow significantly, and the significant flow of air in the cavity 3100 will cause convective heat transfer loss, reducing the heating effect on the heated object.

[0059] Combination Figure 6 and Figure 7As shown, in some embodiments of the present application, the dimension of the first gap 3200 along the horizontal direction is d2, and d2 needs to meet the requirement of not less than 0.3mm and not more than 5mm, for example, d2 is 0.3mm, 0.7mm, 1mm, 1.5mm, 2mm, 3mm, 4mm or 5mm. Specifically, since at least part of the first outer ring portion 1100 extends downward, the dimension of the first gap 3200 along the horizontal direction is the distance between the second inner ring portion 2200 and the part of the first inner ring portion 1200 extending downward, which is closer to the open end of the first gap 3200, and d2 should be understood as the minimum distance along the horizontal direction. After the upper disk body 1000 is connected to the lower disk body 2000, sand blasting is required to remove oil stains on the upper disk body 1000 and the lower disk body 2000 and enhance surface adhesion. In order to prevent sand from being trapped between the second inner ring portion 2200 and the downward extending portion of the first inner ring portion 1200 during the sand blasting process, d2 needs to be designed to be no less than 0.3 mm. At the same time, d2 cannot be too large, otherwise it will easily lead to unsightly appearance.

[0060] Combination Figure 8 , Fig. 9 and Fig.11 As shown, in some embodiments of the present application, when the energy focusing disk surrounds the burner 5000, the first inner ring portion 1200 needs to be arranged alternately with the burner 5000, so as to better provide secondary air for the fire holes located at the peripheral position of the burner 5000.

[0061] Specifically, the burner 5000 has a plurality of fire outlet holes, and the fire outlet holes have a variety of arrangement forms. In order to form a relatively large range of flames, at least some of the fire outlet holes are located at the peripheral position of the burner 5000. By arranging the first inner ring portion 1200 and the burner 5000 to be arranged alternately, the secondary air is easily supplied to the fire outlet holes located at the peripheral position of the burner 5000 through the first inner ring portion 1200 and the burner 5000, so that the combustion of the gas ejected from the fire outlet holes at the peripheral position of the burner 5000 is more complete. It can be understood that the gas needs to be evenly mixed with the air in the burner 5000 before being ejected from the burner 5000 and ignited by the ignition needle. The air evenly mixed with the gas in the burner 5000 is the primary air. When the burner 5000 burns to form a flame, air is drawn from the surrounding environment to assist combustion. This air is called secondary air.

[0062] Furthermore, the distance between the first inner ring 1200 and the burner 5000 should not be too small or too large. If the distance between the first inner ring 1200 and the burner 5000 is too small, the secondary air supply is insufficient, resulting in the inability to fully burn the gas, which will reduce the thermal efficiency. If the distance between the first inner ring 1200 and the burner 5000 is too large, since the secondary air supply is a passive supply, the amount of secondary air is difficult to accurately control. Excessive influx of secondary air will overflow from between the upper plate 1000 and the burner 5000 and take away heat, which is not conducive to the energy gathering of the energy gathering plate. For this reason, combined with Fig.11 As shown, in some embodiments of the present application, the distance between the first inner ring 1200 and the burner 5000 is d3, and d3 needs to satisfy 3mm≤d3≤8mm. For example, d3 is 3mm, 4mm, 5mm, 6mm or 8mm. By optimizing d3, the secondary air supply and thermal efficiency are taken into consideration. In particular, when d3 satisfies 4mm≤d3≤6mm, a better effect is achieved.

[0063] Combination Fig. 9 , Fig.10 , Fig.11 , Fig.12 and Fig.13 As shown, in some embodiments of the present application, the burner 5000 has a main fire hole 5100 (a type of fire outlet hole) and a flame stabilizing groove / flame stabilizing hole 5200 (a type of fire outlet hole), the flame stabilizing groove / flame stabilizing hole 5200 is arranged below the main fire hole 5100, and the highest point of the first inner ring 1200 is arranged to be lower than the flame stabilizing groove / flame stabilizing hole 5200.

[0064] Specifically, compared with the flame stabilizing groove / flame stabilizing hole 5200, the main fire hole 5100 can form a larger flame and generate greater heat. If the gas pressure is unstable or the gas source is incorrect, the flame formed by the main fire hole 5100 is prone to flutter. By setting the flame stabilizing groove / flame stabilizing hole 5200 below the main fire hole 5100, the flame stabilizing groove / flame stabilizing hole 5200 can stabilize the flame formed by the main fire hole 5100 (for example, the flame formed by the flame stabilizing groove / flame stabilizing hole 5200 can stabilize the flame formed by the main fire hole 5100, or the flame stabilizing groove / flame stabilizing hole 5200 diverts the gas to prevent it from being ejected from the main fire hole 5100 when local pressure increases), thereby preventing the flame formed by the main fire hole 5100 from flying up, thereby making the combustion more stable. In this embodiment, the highest point of the first inner ring 1200 is set to be lower than the flame stabilizing groove / flame stabilizing hole 5200, so as to ensure that the secondary air supplemented between the first inner ring 1200 and the burner 5000 can be supplemented from the root of the flame, making the combustion more complete, especially the flame located around the burner 5000.

[0065] Furthermore, along the vertical direction, the distance between the highest point of the first inner ring 1200 and the flame stabilizing groove / flame stabilizing hole 5200 should not be too small or too large. If the distance between the highest point of the first inner ring 1200 and the flame stabilizing groove / flame stabilizing hole 5200 is too small, it is not conducive to the secondary air reaching the root of the flame located at the periphery of the burner 5000, which will lead to an increase in smoke content and reduce thermal efficiency. In addition, the flame at the periphery of the burner 5000 is easy to burn the upper disk body 1000 and / or the lower disk body 2000, interfering with the generation of flames and reducing the life of the energy focusing disk. If the distance between the highest point of the first inner ring 1200 and the flame stabilizing groove / flame stabilizing hole 5200 is too large, it is not conducive to the energy focusing effect of the energy focusing disk. Fig.11 As shown, in some embodiments of the present application, the highest point of the first inner ring portion 1200 is h1 away from the flame stabilizing groove / flame stabilizing hole 5200, and h1 needs to satisfy 1mm≤h1≤5mm, for example, h1 is 1mm, 2mm, 3mm, 4mm or 5mm.

[0066] Combination Fig. 9 and Fig.10 As shown, in some embodiments of the present application, the energy concentrating plate includes a furnace foot 4200, and the furnace foot 4200 is protruded below the lower plate body 2000, so that the furnace foot 4200 can be supported on the support surface 6000, so that the lower plate body 2000 and the support surface 6000 are alternately arranged, and a second gap 3300 is formed between the lower plate body 2000 and the support surface 6000, and the burner 5000 can receive secondary air through the second gap 3300.

[0067] Specifically, the heat of the lower plate 2000 is easily transferred to the support surface 6000 (liquid receiving tray, panel, etc.). If the lower plate 2000 is attached to the support surface 6000, it will easily cause the support surface 6000 to deform or break. Therefore, in this embodiment, the furnace foot 4200 is protruding below the lower plate 2000 to support the furnace foot 4200 to the support surface 6000, so that the second gap 3300 is formed between the lower plate 2000 and the support surface 6000, so that the support surface 6000 can support the energy-gathering disk and reduce the contact area between the lower plate 2000 and the support surface 6000, thereby reducing the heat transferred from the lower plate 2000 to the support surface 6000 and preventing the support surface 6000 from deforming or breaking. In addition, the second gap 3300 is provided to facilitate the provision of secondary air for the combustion of the burner 5000.

[0068] It is understandable that along the vertical direction, the size of the second gap 3300 cannot be too small or too large. If the size of the second gap 3300 is too small, the secondary air cannot effectively pass through the second gap 3300, and the reduced amount of secondary air supply will be unfavorable for full combustion, thereby reducing thermal efficiency. Moreover, when the size of the second gap 3300 is too small, the distance to the support surface 6000 is also closer, and the temperature of the support surface 6000 is easy to increase, which will cause the support surface 6000 to deform or rupture. The size of the second gap 3300 cannot be too large either, because the replenishment of secondary air through the second gap 3300 is a passive supply, which is not conducive to the control of the amount of secondary air. If the second gap 3300 is too large, too much secondary air will flow in, which is not conducive to the energy gathering of the energy gathering disk. For this reason, combined with Fig.10 As shown, in some embodiments of the present application, the second gap 3300 is defined by h2, where h2 is the distance between the bottom surface of the furnace foot 4200 and the bottom surface of the burner 5000 (referring to the bottom surface of the annular head of the burner 5000), and h2 needs to satisfy 5mm≤h2≤15mm. For example, h1 is 5mm, 8mm, 10mm, 13mm or 15mm. By optimizing h1, the secondary air supply through the second gap 3300 and the energy gathering of the energy gathering disk are taken into account.

[0069] Combination Figure 5 As shown, in some embodiments of the present application, the first outer ring portion 1100 is configured to be parallel to the heated object. Specifically, the first outer ring portion 1100 and the heated object are designed to be parallel to each other. In this way, when the high-temperature flue gas flows between the first outer ring portion 1100 and the heated object, a laminar flow is formed. The formation of the laminar flow accelerates the flow of the high-temperature flue gas, thereby strengthening the flushing of the heated object, which is conducive to improving the convective heat transfer coefficient, achieving more efficient heat transfer, and further improving the heat exchange effect. It can be understood that the so-called parallelism means that a flow channel is formed between the first outer ring portion 1100 and the corresponding part of the heated object, and the flow area of ​​the flow channel is relatively constant in the direction of the high-temperature flue gas flow, thereby forming a laminar flow.

[0070] For example, the first outer ring portion 1100 is horizontally arranged, corresponding to the bottom of the heated object, and alternately arranged with the bottom of the heated object. When the heated object is a cooker, the first outer ring portion 1100 is arranged corresponding to the bottom of the cooker, and a flow channel is formed between the first outer ring portion 1100 and the bottom of the pot. When the high-temperature flue gas passes through the first outer ring portion 1100 and the bottom of the pot and is discharged, laminar flow can be formed, thereby strengthening the scouring of the bottom of the pot, thereby improving the convective heat transfer coefficient.

[0071] In order to ensure that an effective laminar flow is formed between the first outer ring portion 1100 and the heated object, Figure 5As shown, in some embodiments of the present application, the energy concentrating disk includes a furnace ear 4100, and the heated object is used to be placed on the furnace ear 4100, so that it is spaced apart from the first outer ring portion 1100, and the distance between the first outer ring portion 1100 and the highest point of the furnace ear 4100 is h3, satisfying 5mm≤h3≤15mm, especially when h3 satisfies 6mm≤h3≤12mm, it has a better laminar flow effect and meets the use of different heated objects.

[0072] Combination Figure 5 As shown, in some embodiments of the present application, the furnace ears 4100 are arranged on the upper plate body 1000, and the furnace feet 4200 are arranged on the lower plate body 2000. By arranging the furnace ears 4100 on the upper plate body 1000 and the furnace feet 4200 on the lower plate body 2000, the furnace ears 4100 and the furnace feet 4200 do not contact each other, so that the heat of the upper plate body 1000 is prevented from being transferred to the lower plate body 2000 through the furnace ears 4100 and the furnace feet 4200, so that the heat of the upper plate body 1000 is further reduced. Transfer to the lower plate body 2000, avoid heat loss of the upper plate body 1000, which is conducive to improving thermal efficiency.

[0073] In the related technology, the energy collecting plate has an integrated support foot, which is installed in the following manner. Corresponding holes are required to be set on the upper plate body 1000 and the lower plate body 2000. The integrated support foot is inserted into the holes of the upper plate body 1000 and the holes of the lower plate body 2000, and then the integrated support foot is welded to the lower plate body 2000 and the upper plate body 1000 respectively, so as to realize the installation of the integrated support foot. The integrated support foot needs to protrude from the upper plate body 1000 and the lower plate body 2000, so that the integrated support foot can be supported on the supporting surface 6000, and the heated object can also be supported on the integrated support foot. However, this solution has some problems. The integrated support feet are in contact with the lower plate body 2000 and the upper plate body 1000 respectively, which strengthens the heat conduction between the upper plate body 1000 and the lower plate body 2000. During the combustion of the burner 5000, the heat generated by the burner 5000 is transferred to the upper plate body 1000, and the heat of the upper plate body 1000 can be transferred to the lower plate body 2000 through the integrated support feet. Since the upper plate body 1000 is closer to the heated object, the excessive dissipation of heat from the upper plate body 1000 is not conducive to the heating of the heated object, and reduces the thermal efficiency. The heat transferred through the integrated support feet is also easily transferred to the support surface 6000 (liquid receiving tray, panel, etc.), making the support surface 6000 easy to deform or crack.

[0074] For this reason, in the present embodiment, furnace ears 4100 and furnace feet 4200 are provided to replace the integrated supporting feet, that is, the furnace ears 4100 are provided to the upper plate body 1000, and the furnace feet 4200 are provided to the lower plate body 2000. It can be understood that the furnace ears 4100 are provided to the upper plate body 1000, that is, the furnace ears 4100 are fixed to the upper plate body 1000, and the furnace feet 4200 are provided to the lower plate body 2000, that is, the furnace feet 4200 are fixed to the lower plate body 2000. When the energy concentrating plate is installed on the gas stove, the furnace feet 4200 are supported to the supporting surface 6000 (liquid receiving tray, panel, etc.), and the furnace ears 4100 are used to support the heated object. Since the cavity 3100 is formed between the upper plate 1000 and the lower plate 2000, the furnace ears 4100 and the furnace feet 4200 are separated from each other and do not contact each other, so that the heat of the upper plate 1000 can be prevented from being transferred to the lower plate 2000 through the contact between the furnace ears 4100 and the furnace feet 4200, and the heat of the upper plate 1000 is not lost so quickly, which is conducive to heating the heated object, thereby effectively improving the thermal efficiency. In addition, it is precisely by reducing the heat transferred from the upper plate 1000 to the lower plate 2000, thereby reducing the heat transferred to the support surface 6000 through the furnace feet 4200, and preventing the support surface 6000 from deformation or cracking.

[0075] The furnace ear 4100 is connected and fixed to the upper plate body 1000 by welding. There are many energy sources for welding, such as gas flame, arc, laser, electron beam, friction or ultrasonic wave, etc. By welding, the furnace ear 4100 can be conveniently and quickly fixed to the upper plate body 1000. The same is true for the furnace foot 4200. The furnace foot 4200 is also connected and fixed to the lower plate body 2000 by welding. By welding, the furnace foot 4200 can be conveniently fixed to the lower plate body 2000.

[0076] Furthermore, the furnace ears 4100 need to be welded to the surface (upper surface) of the upper plate body 1000, and the furnace feet 4200 need to be welded to the surface (lower surface) of the lower plate body 2000. In this way, there is no need to open holes in the upper plate body 1000 and the lower plate body 2000, thereby avoiding damage to the cavity 3100 and preventing liquid leakage.

[0077] Specifically, in the related art, holes are set in the upper plate 1000 and the lower plate 2000 to allow the integrated legs to be inserted, and then fixed by welding. This has high requirements on the welding process, and a gap is easily formed during the welding process. The cavity 3100 can be connected to the outside through the gap, and liquid or other dirt can easily enter the cavity 3100 through the gap, which is not convenient for cleaning. In this embodiment, the furnace ear 4100 is welded to the surface of the upper plate 1000, and the furnace foot 4200 is welded to the surface of the lower plate 2000. The upper plate 1000 and the lower plate 2000 do not need to be set with holes, which prevents damage to the cavity 3100, prevents liquid or other dirt from entering the air cavity, and effectively reduces the difficulty of welding.

[0078] For example, the furnace ear 4100 can be positioned on the upper plate body 1000, and the furnace foot 4200 can be positioned on the lower plate body 2000 by means of a fixture, and then the furnace ear 4100 and the furnace foot 4200 can be welded to the upper plate body 1000 and the lower plate body 2000 respectively by laser welding technology. This processing technology can well control the precision and is conducive to improving the processing efficiency.

[0079] The second aspect of the present application discloses a gas stove, which includes an energy gathering plate of the above-mentioned embodiment. It can be understood that the energy gathering plate of the gas stove of this embodiment adopts the technical solution of the above-mentioned embodiment, and the energy gathering plate includes an upper plate body 1000 and a lower plate body 2000, wherein the upper plate body 1000 includes a first outer ring portion 1100 and a first inner ring portion 1200, and the lower plate body 2000 includes a second outer ring portion 2100 and a second inner ring portion 2200, and the first outer ring portion 1100 is connected to the second outer ring portion 2100, so that a cavity 3100 is formed between the upper plate body 1000 and the lower plate body 2000, and the first inner ring portion 1200 and the second inner ring portion 2200 are alternately arranged, so that a first gap 3200 is formed between the first inner ring portion 1200 and the second inner ring portion 2200, and the first gap 3200 is connected to the cavity 3100. The upper disk body 1000 and the lower disk body 2000 are connected by connecting the first outer ring portion 1100 and the second outer ring portion 2100, and the first inner ring portion 1200 and the second inner ring portion 2200 are alternately arranged to form a non-contact structure, thereby reducing the contact area between the upper disk body 1000 and the lower disk body 2000, which is beneficial to reducing the heat transferred from the upper disk body 1000 to the lower disk body 2000, and the first gap 3200 formed by the alternate arrangement of the first inner ring portion 1200 and the second inner ring portion 2200 can cause a small flow of air in the cavity 3100, further reducing the heat transferred from the upper disk body 1000 to the lower disk body 2000, and effectively improving the thermal efficiency. The remaining technical effects of the energy collecting disk refer to the above technical scheme and will not be repeated here.
