DETAILED DESCRIPTION

[0029] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0030] COMBINATION Figure 1 AND Figure 2According to the embodiment of the utility model, the support 10 of the gas stove 100 comprises: a concentrating part 11 and a catalytic part 12, the inner periphery of the concentrating part 11 surrounds the mounting hole 101; the catalytic part 12 is arranged at the outer periphery of the concentrating part 11, and the catalytic part 12 is arranged along the circumference direction of the concentrating part 11 and forms a flue gas passage 102 that communicates the inside space and the outside space of the catalytic part 12. Specifically, the burner 20 of the gas stove 100 can be arranged in the mounting hole 101, and the concentrating part 11 can concentrate the flame generated by the burner 20, when the cooking utensil is placed on the support 10, the heat energy can be concentrated between the bottom of the cooking utensil and the concentrating part 11, which is beneficial to reduce the energy loss and improve the cooking effect. When the burner 20 is working, incomplete combustion of gas may occur, high-temperature flue gas may be generated, and toxic substances such as carbon monoxide may be carried in the high-temperature flue gas, which may have adverse effects on the human body. The high-temperature flue gas carrying carbon monoxide can diffuse outward from the flue gas passage 102, and when the high-temperature flue gas flows from the concentrating part 11 to the catalytic part 12, it can react with the catalytic part 12. The catalytic part 12 can effectively reduce the activation energy of the reaction between carbon monoxide and oxygen, thereby promoting the conversion of carbon monoxide to carbon dioxide, so that the energy efficiency of the gas stove 100 can be improved while reducing the emission level of carbon monoxide. In addition, the catalytic part 12 is arranged at the outer periphery of the concentrating part 11, which does not affect the transfer of heat in the concentrating part 11 to the cooking utensil. The flame of the burner 20 of the gas stove 100 can directly contact the cooking utensil, which is beneficial to improve the cooking effect. The generated high-temperature flue gas can be concentrated between the cooking utensil and the concentrating part 11 and diffuse outward from the flue gas passage 102. When the high-temperature flue gas flows from the inside space of the catalytic part 12 to the outside space, it can catalytically react with the catalytic part 12 to achieve the treatment of high-temperature flue gas.

[0031] That is, the high-temperature flue gas generated by the burner 20 can be concentrated in the concentrating part 11, thereby ensuring that the heat generated by the gas stove 100 is relatively high and is not easily diffused outward. The high-temperature flue gas can be discharged outward through the flue gas passage 102, and when passing through the flue gas passage 102, the high-temperature flue gas can catalytically react with the catalytic part 12 to reduce the emission amount of carbon monoxide in the flue gas, thereby providing a healthy cooking environment for users.

[0032] According to the embodiment of the utility model, the support 10 of the gas stove 100, by setting up the concentrating part 11 and the catalytic part 12, can concentrate the heat generated by the gas stove 100, which is beneficial to improve the energy efficiency.

[0033] Further, in some embodiments of the present application, the catalytic part 12 protrudes from the surface of the energy gathering part 11, so that the high-temperature flue gas in the energy gathering part 11 is facilitated to contact the catalytic part 12 when moving upward, thereby chemically reacting with the catalytic part 12, achieving the effect of treating flue gas.

[0034] In combination Figure 2 and Figure 4 In some embodiments of the present application, the outer periphery of the energy gathering part 11 is higher than the inner periphery, which can gather heat and reduce energy diffusion. Specifically, the energy gathering part 11 is provided in a disc shape gradually inclined upward along the direction from the inner periphery to the outer periphery, which can achieve the effect of gathering heat. In addition, the disc structure is not easy to accumulate dirt, and is relatively simple to clean, facilitating user cleaning and maintenance.

[0035] In combination Figure 2 In some embodiments of the present application, the catalytic part 12 includes a plurality of fins 121 distributed in the circumferential direction, the plurality of fins 121 are spaced apart, a flue gas passage 102 is formed between two adjacent fins 121, and the surface of the fin 121 is provided with a catalytic layer. Specifically, the plurality of fins 121 can increase the surface area of the catalytic layer, facilitate the high-temperature flue gas to fully contact the catalytic layer, and improve the reaction effect. In addition, the plurality of fins 121 are arranged at intervals, which can also optimize the path of flue gas flow, and the flue gas can be discharged from the flue gas passage 102. In addition, the plurality of fins 121 facilitate to reduce the space occupied by the catalytic part 12, and facilitate to improve the compactness of the support 10.

For example, during manufacturing, the fin 121 can be placed in a solution of transition metal oxide for high-temperature soaking, so as to be hot-dipped on the surface of the fin 121, facilitating to improve the manufacturing efficiency.

[0038] In combination Figure 1 and Figure 2In some embodiments of the utility model, the fin 121 is provided as a sheet extending along the radial direction of the energy collecting part 11, which is beneficial to increase the area of the catalytic layer, thereby improving the effect of the catalytic layer reacting with the flue gas. Further, the inner side edge of the fin 121 is lower than the outer side edge, which can guide the flow when the flue gas flows from the inner side of the catalytic part 12 to the outer side of the catalytic part 12.

[0039] Alternatively, the fin 121 has a first flow guide structure, which gradually inclines upward in the direction away from the energy collecting part 11, thereby playing a flow guide effect and being beneficial to reduce the flow resistance of the flue gas.

[0040] In combination with Figure 1 and Figure 2 In some embodiments of the utility model, the support 10 further comprises a plate body 14, a plurality of fins 121 are arranged at intervals on the plate body 14, the plate body 14 is connected with the outer periphery of the energy collecting part 11, and the plurality of fins 121 are welded or inserted on the upper surface of the plate body 14, which can improve the structural stability of the catalytic part 12.

[0041] Alternatively, the upper surface of the plate body 14 can also be provided with a catalytic layer, thereby further increasing the area of the catalytic layer and improving the catalytic effect.

In addition, the fins 121 are flush with the second part 132 of the support 13, so that the fins 121 can also support the cookware. For example, when the support 13 is relatively small and the cookware is irregular in shape, the cookware may not be able to be lapped on the support 13, resulting in that the cookware cannot be placed or is unstable after being placed.

[0050] In some embodiments of the utility model, the energy collecting part 11 is an integral structure, which can facilitate manufacturing and assembly.

[0051] Of course, the energy concentrating part 11 can also include the plate body 14, which is connected with the energy concentrating part 11 or integrally formed with the energy concentrating part 11, and a plurality of the fins 121 with the catalytic layer are directly welded or inserted on the plate body 14 of the energy concentrating part 11 during assembly.

[0054] In combination with Figure 1 and Figure 2 According to the gas stove 100 in the embodiment of the present application, the bracket 10 includes the energy concentrating part 11 and the catalytic part 12, the energy concentrating part 11 can concentrate the heat of the flame, the catalytic part 12 is connected to the outer periphery of the energy concentrating part 11, can have a catalytic reaction with the flue gas, and will not block the flame, so that the heat generated by the burner 20 can directly reach the cookware, which is beneficial to improve the cooking effect of the gas stove 100.

[0055] The bracket 10 and the gas stove 100 of the gas stove 100 in one specific embodiment of the present application will be described below with reference to the accompanying drawings.

[0056] In the related art, the gas stove is provided with a catalytic plate with a catalyst coating, and the catalytic plate is arranged on the hearth. The catalytic plate separates the flame of the burner from the cookware. Although the catalyst area of the catalytic plate is large, it greatly affects the heating function of the gas stove.

[0057] The present application provides a bracket 10 of a gas stove 100, which simultaneously arranges the energy concentrating part 11 and the catalytic part 12 on the bracket 10. The energy concentrating part 11 can concentrate the heat of the flame, and the catalytic part 12 is connected to the outer periphery of the energy concentrating part 11, can have a catalytic reaction with the flue gas, and will not block the flame, so that the heat generated by the burner 20 can directly reach the cookware, which is beneficial to improve the cooking effect of the gas stove 100. The plurality of fins 121 of the catalytic part 12 have the catalytic layer, which can increase the area of the catalytic layer and improve the catalytic effect. In addition, the bracket 10 can be directly placed on the cooktop 30, has high versatility, and is convenient for users to replace and maintain.

[0058] Specifically, in combination with Figures 1 to 4The support 10 of the gas stove 100 comprises an energy-gathering part 11, a plate body 14, a catalytic part 12 and a support piece 13, the catalytic part 12 comprises a plurality of fins 121, the energy-gathering part 11 is connected with the plate body 14, the fins 121 are fixed on the plate body 14, catalytic layers are attached to both sides of the fins 121, and the support piece 13 is fixed on the edge of the pot support 10 and used for supporting the cooker and the support 10 itself.

[0059] The fins 121 are arranged in the form of a plurality of rows, and the adjacent fins 121 and the bottom of the pot form a plurality of individual flue gas channels 102 (as shown in Figure 2 Fig. 1).

Since the catalytic layers are attached to the surface of the fins 121, the catalysts in the catalytic layers can effectively reduce the activation energy of the reaction of CO and O2, so as to promote the conversion of CO into CO2.

The fins with the catalytic layers can also be arranged on a double-layer or multi-layer energy-gathering ring support.
