The first feature "below", "below" and "below" the second feature include the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0039] like Figures 1 to 4 As shown, this embodiment provides an energy-gathering pan stand, which includes an upper energy-gathering ring 100, a lower energy-gathering ring 200 and a baffle 300. The lower energy-gathering ring 200 is located at the lower side of the upper energy-gathering ring 100, and an annular sealed cavity is formed between the lower energy-gathering ring 200 and the upper energy-gathering ring 100; at least two baffles 300 are provided, and at least two baffles 300 are both provided in the sealed cavity, and at least two baffles 300 are arranged at intervals along the direction from the upper energy-gathering ring 100 to the lower energy-gathering ring 200, and the sealed cavity is divided into at least three heat-insulating cavities 310.

[0040] The above arrangement divides the sealed cavity into at least three insulation cavities 310 arranged from top to bottom through at least two baffles 300, wherein the blocking of at least two baffles and at least three insulation cavities 310 can reduce the transfer of heat to the outside, thereby reducing heat loss and playing the role of gathering heat to improve the efficiency of heat utilization.

[0041] Combination Figure 3 As shown, in some embodiments, a flow channel 320 is formed between adjacent insulation cavities 310, so that the airflow carrying heat flows in different insulation cavities 310. The provision of the flow channel 320 allows heat to flow in different insulation cavities 310, avoiding heat concentration in the uppermost cavity, avoiding the situation where the radiation is increased due to excessively high temperature in the uppermost cavity, and thus reducing heat loss.

[0042] Regarding the positional relationship of each circulation channel 320, in some embodiments, two baffles 300 are provided as an example for explanation, the upper baffle 300 is annular, the outer ring edge 3011 of the upper baffle 300 is connected to the side wall of the sealed cavity, and the inner diameter of the upper baffle 300 is smaller than the inner diameter of the sealed cavity, and the circulation channel 320 is formed between the upper baffle 300 and the sealed cavity; the lower baffle 300 is annular, the inner ring edge 3021 of the lower baffle 300 is connected to the side wall of the sealed cavity, and the outer diameter of the lower baffle 300 is smaller than the outer diameter of the sealed cavity, and the circulation channel 320 is formed between the lower baffle 300 and the sealed cavity. The above arrangement makes the positions of different circulation channels 320 different, so that the heat flow process path is longer, thereby slowing down the speed of flowing from the upper insulation cavity 310 to the lower insulation cavity 310, reducing the heat exchange in the air flow process, and reducing the diffusion of heat to the outside. At the same time, one end of the barrier 300 is a free end, and a flow channel 320 is left between the free end of the barrier 300 and the sealing cavity as a reserved space, so that after the barrier 300 is heated, there is a certain deformation space, thereby preventing the barrier 300 from expanding due to heat and causing irreversible deformation of the entire energy-gathering plate pot rack.

[0043] In some embodiments, the outer periphery of the upper energy focusing ring 100 has a first outer ring connection portion 110, and the inner periphery of the upper energy focusing ring 100 has a first inner ring connection portion 120; the outer periphery of the lower energy focusing ring 200 has a second outer ring connection portion 210, and the inner periphery of the lower energy focusing ring 200 has a second inner ring connection portion 220, the first outer ring connection portion 110 is connected to the second outer ring connection portion 210, and the first inner ring connection portion 120 is connected to the second inner ring connection portion 220. The above arrangement can reduce the production difficulty of the sealing chamber and improve production efficiency.

[0044] The barrier 300 is welded to the side wall of the sealed cavity. The above arrangement ensures that the barrier 300 is firmly connected to the sealed cavity, thereby preventing the barrier 300 from falling off due to deformation such as expansion or contraction during use.

[0045] Among them, the outer circumference of the upper baffle 300 is folded outward to form an outer ring edge 3011, and the outer ring edge 3011 is sandwiched between the first outer ring connecting portion 110 and the second outer ring connecting portion 210. The inner circumference of the lower baffle 300 is folded inward to form an inner ring edge 3021, and the inner ring edge 3021 is sandwiched between the first inner ring connecting portion 120 and the second inner ring connecting portion 220. With the above arrangement, the connection strength between the baffle 300 and the upper energy focusing ring 100 and the lower energy focusing ring 200 is further improved, avoiding the problem of the baffle 300 falling off from the side wall of the sealing cavity after being deformed by heat. It should be noted that turning outward refers to turning in the direction away from the axis of the baffle 300, and turning inward refers to turning in the direction close to the axis of the baffle 300.

[0046] In addition, the above structural arrangement enables, during production, the upper baffle 300 and the upper energy focusing ring 100 can be welded to form a first component, and then the lower baffle 300 and the lower energy focusing ring 200 can be welded to form a second component, and then the first component and the second component are welded. The above arrangement reduces the production difficulty, improves the production efficiency, and is conducive to ensuring the welding accuracy of each baffle 300.

[0047] For ease of understanding, in this embodiment, the upper baffle 300 is defined as an upper baffle 301, and the lower baffle 300 is defined as a lower baffle 302. The upper baffle 301 and the lower baffle 302 are arranged at intervals from the upper energy focusing ring 100 to the lower energy focusing ring 200. The sealed cavity is formed with a first cavity 311, a second cavity 312, and a third cavity 313 in sequence from the upper energy focusing ring 100 to the lower energy focusing ring 200. A first channel 321 is provided between the first cavity 311 and the second cavity 312. A second channel 322 is provided between the second cavity 312 and the third cavity 313. In other words, the first channel 321 is formed on the inner side of the upper baffle 301, between the upper energy focusing ring 100 and the lower energy focusing ring 200; the second channel 322 is formed on the inner and outer sides of the lower baffle 302, between the upper energy focusing ring 100 and the lower energy focusing ring 200. Among them, the first channel 321 is located inside the second channel 322.

[0048] Combination Figures 5 to 7 As shown, since the barrier 300 is a plate-like structure, in order to improve its structural strength and reduce the possibility of deformation after heating, in some embodiments, the barrier 300 is provided with a reinforcing rib 330. Specifically, the reinforcing rib 330 is processed by a stamping process, and the groove formed by stamping in the reinforcing rib 330 is in the shape of a Tesla valve, and the opening of the groove faces the top wall of the circulation channel 320.

[0049] It should be noted that the groove formed by stamping is in the shape of a Tesla valve, which means that the structure of the groove is the same as the shape of the groove structure inside the Tesla valve. The groove inside the Tesla valve has a flow-blocking effect, which is well known to those skilled in the art, so the specific structure of the groove will not be repeated here.

[0050] At the location where the airflow in the energy-gathering pan rack is large, the heat is more concentrated, resulting in a higher temperature at that location, more severe heat radiation to the outside, and more heat loss. In order to solve the above problem, in this embodiment, a plurality of reinforcing ribs 330 are provided, and the plurality of reinforcing ribs 330 are evenly arranged around the axis of the baffle 300, and are arranged radially from the axis of the baffle 300 to the periphery of the baffle 300. The above arrangement allows the heat to flow evenly along the planned path during the flow of the airflow, that is, the airflow in each insulation cavity 310 of the energy-gathering pan rack is relatively balanced, so that the heat in each location of the energy-gathering pan rack is relatively dispersed, and there is no problem of excessively high local temperature, which avoids severe local heat radiation, is conducive to improving the heat collection effect, and improves the overall thermal efficiency.

[0051] In some embodiments, the flow blocking directions of the grooves of the reinforcing ribs 330 in two adjacent baffles 300 are opposite to each other to adapt to the flow direction of heat in each heat insulation cavity 310. For ease of understanding, the reinforcing ribs 330 on the upper baffle 301 are defined as first ribs, and the reinforcing ribs 330 on the lower baffle 302 are defined as second ribs. The grooves formed by stamping in the first ribs open toward the upper energy focusing ring 100, and the grooves formed by stamping in the second ribs open toward the upper baffle 301. The Tesla valve-shaped reinforcing ribs 330 increase the strength of the baffle 300 while slowing down the gas flow, thereby preventing mechanical damage after being exposed to high temperatures.

[0052] In other embodiments, three, four or even five baffles 300 may be provided to correspondingly divide the sealed cavity into four, five or six heat-insulating cavities 310. Wherein, adjacent heat-insulating cavities 310 have flow channels 320, and in the axial direction of the energy-gathering pan support, adjacent flow channels 320 are staggered in the radial direction of the energy-gathering pan support.

[0053] In order to avoid adhesion between the cookware and the upper energy focusing ring 100, which would prevent air from entering between the cookware and the energy focusing plate pot stand and affect combustion efficiency, in some embodiments, a pot stand foot 130 is provided on the side of the upper energy focusing ring 100 away from the lower energy focusing ring 200 to support the cookware.

[0054] This embodiment also provides a gas stove, including the above-mentioned energy-gathering pan rack, which is supported on the liquid tray by the legs 230. By providing the energy-gathering pan rack with at least three heat-insulating cavities 310, the gas stove reduces the amount of heat dissipated after the gas is burned, thereby improving the heat utilization efficiency.

[0055] The lower energy focusing ring 200 has a mounting portion recessed toward the upper energy focusing ring 100, and the support legs 230 are mounted at the mounting portion. With the above arrangement, a position guide is provided for the installation of the support legs 230, thereby improving the installation efficiency of the support legs 230. Three support legs 230 are provided, and the three support legs 230 are evenly spaced around the axis of the lower energy focusing ring 200 to improve the support stability of the energy focusing pan stand and prevent the supported pot from tipping over.

[0056] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
