[0034] In order to more clearly illustrate the technical solutions in the embodiments of the present application or related technologies, the following will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] In the related art, most stoves are open combustion, and the heat generated by combustion easily escapes into the surrounding environment through convection heat transfer and radiation, thereby reducing the heat transfer efficiency and causing energy waste. Among them, the energy-gathering plate and the pot support are also important parts of the gas stove. The pot support is used to support the pot body, and the energy-gathering plate is used to gather heat energy. However, the energy-gathering plate and the pot support in the related art are mostly split or welded structures. The split energy-gathering plate pot support has a complex structure, low production efficiency, and is relatively complicated to assemble; the welded energy-gathering plate pot support has a large contact area due to welding, and is less effective in reducing heat loss.

[0036] For the above situation, please see Figure 1-Figure 3 On the one hand, the present application proposes an energy-gathering disk assembly 1, comprising a main body 10 and support legs 20. Cooking utensils, such as various pots and pans, etc., can be placed above the main body 10, and the support legs 20 are connected to the main body 10 to provide support for the placement of the main body 10. Exemplarily, the support legs 20 can be provided in multiple numbers, such as three, four, five, etc., and the multiple support legs 20 are evenly spaced around the axial direction of the main body 10 and arranged below the main body 10 to provide stable support for the main body 10. Among them, the preparation materials of the main body 10 and the support legs 20 can be metal plates such as steel plates, aluminum plates, and copper plates to improve the strength of the energy-gathering disk assembly 1, and the upper annular body 11, the middle annular body 12, and the lower annular body 13 in the main body 10 can be prepared by sheet metal or stamping processes, and the embodiments of the present application do not impose specific restrictions on this.

[0037] See also Figure 1-Figure 2 In some embodiments of the present application, the energy collecting plate assembly 1 further includes a pot ear 30, which is disposed on a side of the upper annular body 11 away from the middle annular body 12 and connected to the upper annular body 11. In the embodiment of the present application, the shape of the pot ear 30 can be selected and set according to actual conditions, and is not specifically limited here. The setting of the pot ear 30 facilitates providing a placement position for the cooker, so that the energy collecting plate assembly 1 can be applied to more different cookers, thereby improving the universality of the energy collecting plate assembly 1.

[0038] The main body 10 includes an upper ring body 11, a middle ring body 12 and a lower ring body 13 which are stacked in sequence from top to bottom. The upper ring body 11 and the middle ring body 12 enclose a first heat-insulating cavity 111, and a second heat-insulating cavity 121 is formed between the middle ring body 12 and the lower ring body 13. It can be understood that when the energy-gathering disk assembly 1 is placed on a stove for use, the distance between the upper ring body 11 and the stove is the farthest, and the distance between the lower ring body 13 and the stove is the closest. The setting of multiple heat-insulating cavities can concentrate heat in the combustion area to reduce heat loss and improve energy utilization. Among them, the upper ring body 11 and the middle ring body 12 can be in contact with each other. Of course, the upper ring body 11 and the middle ring body 12 can also be arranged without contact.

[0039] The upper annular body 11 and the middle annular body 12 may be fixedly connected, such as by welding or clamping, or the upper annular body 11 and the middle annular body 12 may not be fixedly placed, for example, the upper annular body 11 is placed on the middle annular body 12 in a freely disassembled form. The first heat-insulating cavity 111 may be set as a sealed cavity to better reduce heat loss; or the first heat-insulating cavity 111 may be set as a non-sealed cavity; or a heat-insulating filler may be set in the first heat-insulating cavity 111, such as aerogel or other heat-insulating materials, which are not specifically limited here, and the second heat-insulating cavity 121 may be set in the same way as the first heat-insulating cavity 111.

[0040] The lower annular body 13 is provided with a first through slot 131 , the support leg 20 is connected to the lower annular body 13 , and the support leg 20 penetrates into the second heat insulation cavity 121 through the first through slot 131 and is connected to the middle annular body 12 .

[0041] Specifically, the support foot 20 can be connected to the middle ring body 12 by welding or clamping, and the support foot 20 is connected to the lower ring body 13, so that there is no other contact connection between the lower ring body 13 and the middle ring body 12, and they are only connected through the support foot 20. The support foot 20 is inserted into the first through groove 131, and the groove wall of the first through groove 131 on the lower ring body 13 can also provide the support foot 20 with a limit in the circumferential direction of the support foot 20, so as to reduce the possibility of shaking of the support foot 20 and make the setting of the support foot 20 more stable.

[0042] It should be noted that the embodiment of the present application forms an insulating cavity between the upper annular body 11, the middle annular body 12 and the lower annular body 13 by stacking them from top to bottom, and the upper annular body 11 and the middle annular body 12, and the middle annular body 12 and the lower annular body 13. By setting it in this way, on the one hand, the material of the main body 10 can absorb the heat radiated outward during the combustion process, so that the environment where the burner is located is a relatively high temperature, which is conducive to the full combustion of the mixed gas. Of course, in this process, the main body 10 can also radiate the absorbed heat to the pot above it to heat the pot again. In addition, multiple insulating cavities are formed in the main body 10, and the insulating cavities also play a role in blocking the heat radiated outward during the combustion process of the burner. It can be seen that the scheme of the present application is conducive to the concentration of heat, which can reduce heat loss and improve energy utilization. At the same time, in the embodiment of the present application, there may be no direct connection between the lower ring body 13 and the upper ring body 11 and the middle ring body 12. The middle ring body 12 and the lower ring body 13 are connected only by setting support feet 20, thereby reducing the welding points between the lower ring body 13 and the middle ring body 12, thereby reducing the heat conduction from the middle ring body 12 to the lower ring body 13, that is, reducing the contact area between the lower ring body 13 and the middle ring body 12, reducing the heat conduction loss downward, and improving the heat utilization.

[0043] For further information, see Figure 1-Figure 2 In some embodiments of the present application, a third through slot 114 is provided on the upper annular body 11, and the pot ear 30 is fixedly connected to the upper annular body 11 through the third through slot 114. The pot ear 30 contacts the groove wall of the third through slot 114, and the third through slot 114 provides an installation and positioning space for the pot ear 30, so that the installation of the pot ear 30 is more stable and the risk of position displacement of the pot ear 30 is reduced.

[0044] There may be a plurality of pot ears 30, such as three, four, five, etc. The plurality of pot ears 30 are evenly spaced around the axial direction of the main body 10 above the upper annular body 11 to provide stable support for the cooker.

[0045] It should be noted that if Figure 2-Figure 3 As shown, the first heat insulation cavity 111 can also be connected to the outside through the third through groove 114, so that the first heat insulation cavity 111 can be naturally filled with air through the third through groove 114, thereby effectively preventing heat loss and improving the energy gathering effect. At the same time, the main body 10 can also release air through the gap here after the heated air expands, thereby preventing the upper annular body 11 and the middle annular body 12 from deforming.

[0046] Please continue to see Figure 2-Figure 3In some embodiments of the present application, the second heat-insulating cavity 121 is connected to the outside through the first through slot 131. Specifically, the support leg 20 passes through the first through slot 131 to extend out of the second heat-insulating cavity 121, and there may be a gap between the support leg 20 and a portion of the groove wall of the first through slot 131. Through the gap, the second heat-insulating cavity 121 can be naturally filled with air, thereby effectively preventing heat loss and improving the energy-gathering effect. At the same time, the main body 10 can also release air through this gap after the heated air expands, thereby preventing the middle annular body 12 and the lower annular body 13 from deforming.

[0047] See also Figure 3-Figure 4 In some embodiments of the present application, the upper annular body 11 and the middle annular body 12 are stacked, and the main body 10 also includes a partition 14, which is located between the upper annular body 11 and the middle annular body 12. The first insulation cavity 111 is formed by the upper annular body 11, the partition 14 and the middle annular body 12. The partition 14 is arranged to extend axially around the main body 10, and the upper annular body 11, the partition 14 and the middle annular body 12 can all serve as the side wall portion of the first insulation cavity 111.

[0048] Specifically, Figure 4-Figure 5 As shown, the partition 14 is arranged on the upper ring body 11, and the bottom end of the partition 14 is in contact with the middle ring body 12, wherein the bottom end of the partition 14 and the middle ring body 12 can be abutted or welded. Preferably, spot welding is performed between the partition 14 and the middle ring body 12 around the axial spacing of the main body 10 to reduce the contact area between the partition 14 and the middle ring body 12.

[0049] Alternatively, the partition 14 is arranged on the middle ring body 12, and the top end of the partition 14 is in contact with the upper ring body 11; alternatively, a portion of the partition 14 is arranged on the upper ring body 11, and the bottom end of this portion of the partition 14 is in contact with the middle ring body 12, and the other portion is arranged on the middle ring body 12, and the top end of this portion of the partition 14 is in contact with the upper ring body 11, thereby forming a hollow first insulation cavity 111, which is beneficial to the concentration of heat.

[0050] For further information, see Figure 4-Figure 5 In some embodiments of the present application, a plurality of partitions 14 are provided on the upper ring body 11, and the plurality of partitions 14 are arranged at intervals along the radial direction of the upper ring body 11 so as to form an annular insulation cavity between the upper ring body 11 and the middle ring body 12, and the plurality of partitions 14 are conducive to forming a relatively closed first insulation cavity 111.

[0051] The upper annular body 11, the middle annular body 12 and the lower annular body 13 in the main body are all annular, so the upper annular body 11, the middle annular body 12 and the lower annular body 13 all have an annular outer edge portion and an annular inner edge portion that are arranged opposite to each other. The number of the partitions 14 is preferably two, one is arranged at the outer edge portion of the upper annular body 11, and the other is arranged at the inner edge portion of the upper annular body 11, so that the connection between the upper annular body 11 and the middle annular body 12 is more stable, and compared with the arrangement of multiple partitions 14, the arrangement of two partitions 14 also makes the contact area between the upper annular body 11 and the middle annular body 12 smaller.

[0052] See also Figure 6 In some embodiments of the present application, a first extension portion 122 is provided at the outer edge of the middle ring body 12, and the first extension portion 122 extends toward the lower ring body 13. The first extension portion 122 can be extended in a curved shape or in a straight line, and the end of the first extension portion 122 contacts the lower ring body 13; a second extension portion 112 is provided at the inner edge of the upper ring body 11, and the inner edge of the lower ring body 13 extends toward the upper ring body 11, and the inner edge of the lower ring body 13 contacts the second extension portion 112.

[0053] Specifically, taking the partition 14 including the first partition 141 and the second partition 142 as an example, the two ends of the first partition 141 are respectively connected to the outer edge of the upper ring body 11 and the outer edge of the middle ring body 12, and the two ends of the second partition 142 are respectively connected to the inner edge of the upper ring body 11 and the inner edge of the middle ring body 12, thereby the upper ring body 11, the first partition 141, the upper surface of the middle ring body 12 and the second partition 142 together form a complete first heat insulation cavity 111. The lower ring body 13 contacts the end of the first extension part 122, and the inner edge of the lower ring body 13 contacts the second extension part 112, thereby the lower surface of the middle ring body 12, the first extension part 122, the lower ring body 13, the second extension part 112 and the second partition 142 together form a complete second heat insulation cavity 121. At this time, there is no direct contact connection between the upper annular body 11 and the lower annular body 13, and the upper annular body 11 is in contact with the lower annular body 13 only through the second extension part 112, so the second extension part 112 does not belong to the side wall of the first insulation cavity 111, but belongs to the side wall part of the second insulation cavity 121; there is no direct contact connection between the middle annular body 12 and the lower annular body 13, and the middle annular body 12 is in contact with the lower annular body 13 only through the first extension part 122, and the first extension part 122 does not belong to the side wall of the first insulation cavity 111, but belongs to the side wall part of the second insulation cavity 121. It can be understood that the first insulation cavity 111 is used to isolate most of the heat inside the main body 10 to reduce heat loss. The first insulation cavity 111 is closer to the fire source than the second insulation cavity 121, so the temperature in the first insulation cavity 111 is higher than the temperature in the second insulation cavity 121. As a result, the contact area between the lower annular body 13 and the upper annular body 11 and the middle annular body 12 is reduced, and the heat conduction from the upper annular body 11 and the middle annular body 12 to the lower annular body 13 is reduced, that is, the heat loss caused by conduction downward is reduced.

[0054] See also Figure 5-Figure 6 In some embodiments of the present application, an inner edge and an outer edge of the upper ring body 11 are provided with an inward-locking structure 113, which extends vertically downward, and the inner edge and the outer edge of the lower ring body 13 are both located in the corresponding inward-locking structure 113.

[0055] Specifically, the inner buckle structure 113 can contact both the inner edge and the outer edge of the lower ring body 13. On the one hand, the inner buckle structure 113 can play a role in positioning and limiting the installation of the lower ring body 13, so that the setting of the lower ring body 13 is more stable. On the other hand, when the upper ring body 11 is placed on the middle ring body 12, the inner buckle structure 113 is used to connect with the lower ring body 13 to install the upper ring body 11, and the setting of the inner buckle structure 113 facilitates the subsequent disassembly and cleaning of the upper ring body 11. In addition, the inner buckle structure 113 wraps the outer edge and inner edge of the lower ring body 13, thereby reducing the external impurities from entering the main body 10.

[0056] See also Figure 6 In some embodiments of the present application, a second through groove 123 is opened on the middle ring body 12, and the upper end of the supporting foot 20 passes through the second through groove 123 and is fixedly connected to the middle ring body 12. The supporting foot 20 contacts the groove wall of the second through groove 123. The second through groove 123 provides installation and positioning space for the supporting foot 20 to reduce the risk of position displacement of the supporting foot 20.

[0057] See also Figure 6-Figure 7 In some embodiments of the present application, a step structure 21 is provided at the upper end of the supporting foot 20 , part of the step structure 21 extends into the second through groove 123 , and the step structure 21 abuts against a side of the middle ring body 12 close to the lower ring body 13 .

[0058] Specifically, the step structure 21 has a first side surface 211 and a second side surface 212 that are adjacently arranged, the first side surface 211 contacts the groove wall of the second through groove 123, and the second side surface 212 contacts the surface of the middle ring body 12 facing the lower ring body 13, and the step structure 21 can provide a limit for the middle ring body 12 to reduce the position deviation of the middle ring body 12 relative to the support foot 20. When the main body 10 is placed on the table through the support foot 20, the support foot 20 can also provide better support for the main body 10.

[0059] In some embodiments of the present application, the connection between the support foot 20 and the lower annular body 13 is threaded. Figure 6-Figure 7 As shown, a fixing portion 132 is provided on the side of the lower ring body 13 away from the middle ring body 12, and a screw hole 22 is provided on the support foot 20. When the support foot 20 is inserted into the second through groove 123 on the middle ring body 12 via the first through groove 131 on the lower ring body 13, the screw hole 22 on the support foot 20 corresponds to the fixing portion 132 on the lower ring body 13. Bolts can be inserted into the fixing portion 132 and the screw hole 22 and screwed therewith, thereby fixing the support foot 20 and the lower ring body 13.

[0060] The screw connection method can facilitate subsequent disassembly and installation. Of course, the support leg 20 and the lower annular body 13 can also be fixed by welding, which is not specifically limited here.

[0061] In a second aspect, the present application also provides a gas stove, comprising a burner and an energy collecting plate assembly 1 as described in any of the above embodiments, wherein a central hole 15 (such as Figure 7As shown), the pot ears 30 provided can be used to support the bottom of the pot, and the supporting feet 20 provided can be used to support the main body 10 and the cooking utensils, so as to place the energy gathering plate assembly 1 on the stove panel, and the specific structure of the energy gathering plate assembly 1 refers to the above-mentioned embodiments. Since the gas stove adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.
