[0028] In order to enable those skilled in the art to understand the present application more clearly, the technical solutions in the embodiments of the present application will be clearly and completely described below 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 making creative efforts shall fall within the scope of protection of this application.
[0029] Existing gas stoves are equipped with a disc-shaped cooker support to separate the secondary air required for combustion from the high-temperature flue gas generated by combustion, so that the high-temperature flue gas generated by combustion is gathered in the energy-gathering disk, thereby enhancing the heat energy exchange between the high-temperature flue gas and the cooker, reducing radiation and convection heat loss, and playing a role in gathering heat energy and heat insulation.
[0030] In the related art, the top surface of the energy-gathering disk located on the outside is a plane. Since the bottom of the cookware, such as the pot, is an arc surface, along the radial direction of the energy-gathering disk, the distance between the flat part of the top surface of the energy-gathering disk and the bottom of the cookware gradually increases from the center to the periphery. Therefore, the flow area of the flue gas gradually increases from the inside to the outside. When the flue gas flow rate does not change, the flow velocity of the flue gas gradually decreases from the center to the periphery, resulting in a gradual deterioration of the heat exchange effect and affecting energy efficiency.
[0031] Based on the above technical problems, the present application provides an energy-gathering plate and a gas stove, in which the distance between the top surface of the energy-gathering plate and the bottom of the cooker is roughly the same or consistent, so that the flue gas flow rate on the top surface of the energy-gathering plate always maintains a high flow rate, to ensure that the flue gas at the bottom of the cooker maintains high-speed convection heat exchange, thereby enhancing the heat exchange effect and improving energy efficiency.
[0032] Based on the above design ideas, in the first aspect of the present application, the present application provides an energy gathering disk 100. Figure 1 shows a schematic structural diagram of a gas stove in one or more embodiments of the present application, Figure 2 Shown Figure 1 The structural diagram of the energy-gathering disk in Figure 3 Shown Figure 2 A top view of Figure 4 Shown Figure 3 AA cross-section diagram of the combined Figures 1-4 The energy-gathering disk 100 includes a first disk body 101 and a second disk body 102. The second disk body 102 is connected to the peripheral side of the outer edge of the first disk body 101. At least a portion of the second disk body 102 is inclined in a direction away from the first disk body 101. The outer side of the inclined portion of the second disk body 102 is higher than the inner side of the inclined portion of the second disk body 102.
[0033] The energy-gathering disk 100 provided in the present application has at least a portion of the second disk body 102 tilted away from the first disk body 101, and the outer side of the tilted portion of the second disk body 102 is higher than the inner side of the tilted portion of the second disk body 102, that is, the second disk body 102 tilts upward and outward of the energy-gathering disk 100. When the cooker is placed on the energy-gathering stove with the energy-gathering disk 100, the distance between the tilted portion of the second disk body 102 of the cooker and the bottom of the cooker is roughly the same, so as to ensure that the heat exchange area between the tilted portion of the second disk body 102 and the bottom of the cooker is close to the same, so that the smoke at the bottom of the cooker maintains high-speed convection heat exchange with the bottom of the cooker, thereby enhancing the heat exchange effect and improving energy efficiency. Figure 2 -Attached Figure 4 , the specific details of the energy-gathering disk 100 are further described.
[0034] Combine Figure 1 as well as Figure 2 According to one embodiment of the present application, the first plate body 101 of the energy concentrating plate 100 has an annular structure, and the combustion part of the burner 200 is placed at the central opening of the first plate body 101. When the combustion part of the burner 200 is assembled into the energy concentrating opening of the energy concentrating plate 100, the energy concentrating plate 100 can form a semi-enclosed combustion space between the burner 200 and the bottom of the cooker. The high-temperature flue gas generated by the combustion of the burner 200 is gathered in the combustion space to enhance the heat energy exchange between the high-temperature flue gas and the bottom of the cooker pot, thereby improving the combustion thermal efficiency.
[0035] Combine Figures 2 to 4 According to one embodiment of the present application, at least a portion of the first plate body 101 of the energy concentrating plate 100 may also be arranged at an angle, with the outer side of the first plate body 101 being higher than the inner side of the first plate body 101, that is, the first plate body 101 is inclined upward toward the outer side of the energy concentrating plate 100. When a cooker is placed on a gas stove having the energy concentrating plate 100, the distance between the inclined portion of the first plate body 101 of the cooker and the bottom of the cooker is roughly the same, so as to ensure that the heat exchange area between the inclined portion of the first plate body 101 and the bottom of the cooker is nearly the same, so that the smoke at the bottom of the cooker maintains high-speed convective heat exchange with the bottom of the cooker, thereby enhancing the heat exchange effect and improving energy efficiency.
[0036] Combine Figures 2 to 4In one embodiment, the entire first plate 101 is tilted so that the top surface of the entire first plate 101 is approximately the same distance from the bottom of the cooker. In another embodiment, only a portion of the first plate 101 may be tilted, and this application does not limit this.
[0037] Combine Figures 2 to 4 In one embodiment, the top surface of the first plate 101 can be an inclined surface. If the top surface of the first plate 101 is an inclined surface, since most cookware used on gas stoves is pots, which often have curved bottoms, and since the first plate 101 is located near the center of the bottom of the cookware, the slope of the inclined surface of the first plate 101 can be roughly consistent with the curvature of the cookware's bottom at an offset from the center. That is, the slope of the inclined surface of the first plate 101 can be 25-45 degrees. This ensures that the distance between the top surface of the first plate 101 and the offset from the bottom of the cookware is approximately consistent, thereby enhancing heat exchange and improving energy efficiency. In another embodiment, the top surface of the first plate 101 can also be a curved surface or a combination of an inclined surface and a curved surface, which can also ensure that the distance between the top surface of the first plate 101 and the offset from the bottom of the cookware is approximately consistent to a certain extent.
[0038] Combine Figures 2 to 4 According to one embodiment of the present application, the energy concentrating disk 100 further includes a limiting wall 103, which is connected to the circumferential side of the inner edge of the first disk body 101. The limiting wall 103 is inclined in the direction away from the first disk body 101, and the inner side of the limiting wall 103 is lower than the outer side of the limiting wall 103, that is, the first disk body 101 and the limiting wall 103 can form an oil collecting tank 104 to receive the oil overflowed during cooking by the cooker, and prevent the oil from entering the burner 200, so as to improve the cleanliness of the gas stove and ensure the normal operation of the gas stove to a certain extent.
[0039] Combine Figures 2 to 4 According to one embodiment of the present application, the limiting wall 103 is also an annular structure, and the combustion portion of the burner 200 passes through the central through-hole of the limiting wall 103. A gap may be provided between the inner side of the limiting wall 103 and the combustion portion of the burner 200, and secondary air may be supplied to the combustion portion of the burner 200 through the gap between the two, thereby improving the combustion efficiency of the burner 200. In addition, since the limiting wall 103 is tilted away from the first disk 101, it can also guide the secondary air to gather as much as possible in the direction of the combustion portion of the burner 200, thereby improving the combustion efficiency of the burner 200.
[0040] According to an embodiment of the present application, the combustion portion of the burner 200 may be a single-fire hole structure or a multi-fire hole structure, and the present application does not impose any limitation on this.
[0041] Combine Figures 2 to 4The second plate 102 is also an annular structure, connected to the outer edge of the first plate 101. In one embodiment, the entire second plate 102 is tilted so that the top surface of the entire second plate 102 is approximately the same distance from the bottom of the cookware. In another embodiment, only a portion of the second plate 102 may be tilted, and this application is not limited thereto.
[0042] Combine Figures 2 to 4 In one embodiment, the top surface of the second plate 102 can be an inclined surface. If the top surface of the second plate 102 is an inclined surface, since most cookware used on gas stoves is pots, which often have curved bottoms, and since the second plate 102 is located near the edge of the bottom of the cookware, the slope of the inclined surface of the second plate 102 can be roughly consistent with the curvature of the edge of the bottom of the cookware. That is, the slope of the inclined surface of the second plate 102 can be 2-10 degrees. This ensures that the distance between the top surface of the second plate 102 and the edge of the bottom of the cookware is approximately consistent, thereby enhancing heat exchange and improving energy efficiency. In another embodiment, the top surface of the second plate 102 can also be a curved surface or a combination of an inclined surface and a curved surface, which can also ensure that the distance between the top surface of the second plate 102 and the edge of the bottom of the cookware is approximately consistent.
[0043] According to one embodiment of the present application, the first plate body 101, the second plate body 102, and the limiting wall 103 that constitute the energy collecting plate 100 can be integrally formed to provide the energy collecting plate 100 with sufficient strength for use. Furthermore, because the slope of the second plate body 102 is smaller than that of the first plate body 101, the energy collecting plate 100 can be roughly formed into a structure with a high outer surface and a low inner surface to match the shape of the bottom of the cookware. This allows the top surface of the energy collecting plate 100 to be approximately the same distance from the bottom of the cookware, and the heat exchange area between the top surface of the energy collecting plate 100 and the bottom of the cookware to be approximately the same, thereby enhancing the heat exchange effect and improving energy efficiency. Furthermore, it should be noted that the heat exchange area described in the present application refers to the product of the distance between a certain position on the top surface of the energy collecting plate 100 and the bottom of the cookware and the circumference of the circle containing that position.
[0044] Based on the same design concept, in the second aspect of the present application, the present application also provides a gas stove, which includes a cooker bracket 300, a burner 200 and the above-mentioned energy collecting plate 100, wherein the energy collecting plate 100 is placed on the cooker bracket 300, and the burner 200 is placed in the cooker bracket 300.
[0045] The gas stove provided in the present application can ensure that the flue gas at the bottom of the cooker maintains high-speed convection heat exchange with the bottom of the cooker, thereby enhancing the heat exchange effect and improving energy efficiency.
[0046] Figure 5 Shown Figure 1 A top view diagram of Figure 6Shown Figure 5 BB cross-section diagram. Figure 5 as well as Figure 6 As mentioned above, the burner 200 of the present application includes a base 201 and a combustion part 202. The base 201 is placed at the bottom of the cookware bracket 300, and the combustion part 202 is connected to the base 201. The gap of the combustion part 202 is placed on the inner side of the energy collecting disk 100. Secondary air can be supplemented into the combustion part 202 of the burner 200 through the gap between the two, thereby improving the combustion efficiency of the burner 200. The combustion part 202 of the burner 200 can be a single fire hole structure or a multi-fire hole structure, and the present application does not impose any restrictions on this.
[0047] Combine Figure 5 as well as Figure 6 In one embodiment, the cooker support 300 includes a support body 301 and multiple lugs 302. The bottom of the support body 301 can be supported on the circumference of the top surface of the base 201. The multiple lugs 302 are spaced apart around the circumference of the top surface of the support body 301. The multiple lugs 302 are arranged at intervals around the circumference of the support body 301 to support the cooker. In another embodiment, the support body 301 can also be placed directly on the stove.
[0048] Combine Figure 6 According to one embodiment of the present application, the energy concentrating plate 100 is placed on the top surface of the bracket body 301 and below the multiple stove ears 302. The distance between the outer side of the second plate body 102 and the top surface of the stove ear 302 is h1, where 3mm≤h1≤10mm, and the distance between the outer side of the second plate body 102 and the top surface of the stove ear 302 is h2, where 6mm≤h2≤15mm, so that the top surface of the second plate body 102 as a whole has a high outer side and a low inner side structure. When the cooker is placed on the gas stove with the energy concentrating plate 100, the distance between the top surface of the second plate body 102 of the cooker and the bottom of the cooker is roughly the same, so as to ensure that the heat exchange area between the top surface of the second plate body 102 and the bottom of the cooker is close to the same, so that the smoke at the bottom of the cooker maintains high-speed convective heat exchange with the bottom of the cooker, thereby enhancing the heat exchange effect, improving energy efficiency, and having good practicality.
