[0027] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:
[0028] This utility model discloses a stove frame for stoves; please refer to [link / reference]. Figures 1 to 3The furnace frame includes an energy-concentrating plate 1 and a pot support 2; the energy-concentrating plate 1 includes an upper plate 11 and a lower plate 12, which form a cavity. It also includes an intermediate layer 13, which is located between the upper plate 11 and the lower plate 12. The intermediate layer 13 divides the cavity into a first heat-insulating cavity 14 and a second heat-insulating cavity 15. The upper and lower surfaces of the intermediate layer 13 are provided with heat-insulating coatings. The pot support 2 is disposed on the upper plate 11 of the energy-concentrating plate 1.
[0029] In this embodiment, the energy-concentrating plate 1 is annular and is adapted to fit the burner of the gas stove, surrounding the burner. The upper surface of the energy-concentrating plate 1 is arc-shaped with the outer periphery higher than the inner periphery, forming an energy-concentrating cavity. When the stove is in use, the upper surface of the energy-concentrating plate 1 faces the bottom of the pot, creating a semi-enclosed combustion space between the burner and the bottom of the pot. The high-temperature flue gas generated during combustion can be concentrated in the energy-concentrating cavity, enhancing the heat exchange between the high-temperature flue gas and the bottom of the pot and improving combustion efficiency.
[0030] Both the upper disc 11 and the lower disc 12 are annular with inner holes. The inner holes of the upper disc 11 and the lower disc 12 are coaxially arranged, and the upper disc 11 is fastened to the lower disc 12, that is, the inner edge of the upper disc 11 is in close contact with the inner edge of the lower disc 12, and the outer edge of the upper disc 11 is in close contact with the outer edge of the lower disc 12. Thus, the upper disc 11 and the lower disc 12 are fastened together and form a cavity. At the same time, the inner holes of the upper disc 11 and the lower disc 12 combine to form the central through hole of the energy-concentrating disc 1, which is used to pass through the burner, so that the energy-concentrating disc 1 is arranged around the periphery of the burner. The cavity is filled with air to take advantage of the poor thermal conductivity of air, so that the energy-concentrating disc 1 can be insulated and heat-preserved, thereby ensuring the high temperature state of the high-temperature flue gas in the energy-concentrating cavity to a certain extent and improving the combustion thermal efficiency.
[0031] The intermediate layer 13 divides the cavity into a first insulation cavity 14 and a second insulation cavity 15, which can achieve multiple insulation, further improve the energy-concentrating and heat-preserving effect of the energy-concentrating disk 1, effectively block radiative heat dissipation, reduce heat loss, and improve heat utilization rate. Setting the first insulation cavity 14 and the second insulation cavity 15 as independent sealed chambers can prevent heat loss due to air flow, further ensure the energy-concentrating and heat-preserving effect of the energy-concentrating disk 1, reduce heat loss, and improve heat utilization rate.
[0032] Because the upper plate 11 is closer to the combustion flame formed by the burner, its temperature is relatively higher. The higher the temperature of the upper plate 11, the more heat is radiated, resulting in some heat loss. To reduce heat loss, heat-insulating coatings are provided on both the upper and lower surfaces of the intermediate layer 13. This reduces the heat transferred from the first insulation layer to the second insulation cavity 15, and also reduces the heat radiated from the upper plate 11 to the lower plate 12. This effectively reduces the heat loss from the upper plate 11, maintaining a relatively high temperature in the first insulation cavity 14, enhancing the temperature field of the high-temperature heat energy mass gathered above the upper plate 11, and resulting in a higher combustion flame temperature.
[0033] The pot support is used to support the bottom of the pot. The pot support 2 includes multiple support parts connected to the upper surface of the upper plate 11. The multiple support parts are spaced apart around the central through hole of the energy-concentrating plate 1. The support parts are located inside the outer edge of the upper plate 11, so that the support parts are not easily in direct contact with the external cold air, preventing the support parts from dissipating heat to the outside. During the combustion process of the burner, the heat energy absorbed by the support parts can be effectively conducted to the bottom of the pot to heat the bottom of the pot, reducing heat loss and improving the utilization rate of combustion heat energy.
[0034] In the furnace frame of this utility model, such as Figures 3 to 5 As shown, the intermediate layer 13 is provided with a corrugated structure 131. The corrugated structure 131 is a structure with approximately wavy, undulating surfaces on the surface of the intermediate layer 13. The corrugated structure 131 can be provided only on the upper surface of the intermediate layer 13, only on the lower surface of the intermediate layer 13, or simultaneously on both the upper and lower surfaces of the intermediate layer 13. The corrugated structure 131 can increase the contact area between the intermediate layer 13 and the air, improve the heat exchange efficiency between the intermediate layer 13 and the air, thereby increasing the heat absorbed by the first insulation cavity 14 and / or the second insulation cavity 15, reducing heat loss to the outside, and further improving the utilization rate of combustion heat energy.
[0035] In the furnace frame of this utility model, such as Figures 3 to 5 As shown, the corrugated structure 131 is a corrugated section provided on the intermediate layer 13. The corrugated section forms a wave shape with high and low undulations on both the upper and lower surfaces of the intermediate layer 13. In this way, the contact area between the intermediate layer 13 and the air in the first insulation cavity 14 and the second insulation cavity 15 can be increased at the same time, so as to further improve the heat exchange efficiency between the intermediate layer 13 and the air. This can simultaneously increase the heat absorbed by the first insulation cavity 14 and the second insulation cavity 15, reduce the heat loss to the outside, and further improve the utilization rate of combustion heat energy.
[0036] In the furnace frame of this utility model, such as Figure 3As shown, at least two corrugated sections are spaced apart along the height of the intermediate layer 13. The number of corrugated sections can be two or more. By increasing the number of corrugated sections, the contact area between the intermediate layer 13 and the air can be further increased, and the heat exchange efficiency between the intermediate layer 13 and the air can be improved. This can further increase the heat absorbed by the first insulation cavity 14 and / or the second insulation cavity 15, reduce heat loss to the outside, and further improve the utilization rate of combustion heat energy.
[0037] In the furnace frame of this utility model, such as Figures 4 to 6 As shown, the upper plate 11 includes an upper flange 111, a plate surface 112, and a lower flange 113. The upper flange 111 extends outward from the upper edge of the plate surface 112, and the lower flange 113 extends downward from the lower edge of the plate surface 112, forming an annular channel for the energy-concentrating plate 1. The upper flange 111 is a horizontal annular shape, and the lower flange 113 is a vertical annular shape. The annular channel allows the burner to pass through from bottom to top, so that the flame generated by the burner can be contained by the plate surface 112.
[0038] In the furnace frame of this utility model, such as Figures 4 to 6 As shown, the lower plate 12 includes an outer wall surface 121, a plate bottom 122, and an inner wall surface 123. The outer edge of the plate bottom 122 extends upward to form the outer wall surface 121, and the inner edge of the plate bottom 122 extends upward to form the inner wall surface 123. The upper edge of the outer wall surface 121 is connected to the upper flange 111, and the upper edge of the inner wall surface 123 is connected to the lower flange 113. The connection between the upper edge of the outer wall surface 121 and the upper flange 111 allows for a stable connection between the outer edge of the lower plate 12 and the outer edge of the upper plate 11. The connection between the upper edge of the inner wall surface 123 and the lower flange 113 allows for a tight fit between the inner edge of the lower plate 12 and the inner edge of the upper plate 11.
[0039] In the furnace frame of this utility model, such as Figures 4 to 6 As shown, the outer wall surface 121 extends outward from bottom to top; the inner wall surface 123 extends inward from bottom to top, extending upward to below the disk surface 112 and connecting with the lower flange 113 from the outside of the lower flange 113. The outer wall surface 121 is gradually expanding from bottom to top, and the inner wall surface 123 is gradually contracting from bottom to top. The outward expansion trend of the upper edge of the outer wall surface 121 and the inward contraction trend of the upper edge of the inner wall surface 123 enable the connection points between the outer wall surface 121 and the inner wall surface 123 and the upper flange 111 and the lower flange 113, respectively, to have a tendency to pull and limit each other, thereby improving the connection strength between the upper disk 111 and the lower disk 12.
[0040] In the furnace frame of this utility model, such as Figures 4 to 6As shown, the upper edge of the intermediate layer 13 extends outward from the upper connecting portion 132, and the lower edge of the intermediate layer 13 extends downward to the lower connecting portion 133. The upper connecting portion 132 is connected to the lower surface of the upper flange 111, and the lower edge of the lower connecting portion 133 is connected to the disk surface 112. In this way, the connection area between the intermediate layer 13 and the upper disk 11 can be increased to improve the connection stability.
[0041] In the furnace frame of this utility model, such as Figure 1 and Figure 2 As shown, the stove rack also includes support legs 3, which are connected to the lower plate 12. Multiple support legs 3 are arranged at intervals along the circumference of the lower plate 12. The support legs 3 support the energy-concentrating plate 1 on the gas stove panel, allowing the lower plate 12 to be lifted from the gas stove panel to a predetermined height. This creates an air supply channel, allowing air to enter the annular gap between the energy-concentrating plate 1 and the burner through the space between the energy-concentrating plate 1 and the panel, supplementing the burner's combustion with air and ensuring more complete gas combustion.
[0042] In the furnace frame of this utility model, such as Figure 2 and Figure 4 As shown, the stove rack also includes foot pads 4. The support leg 3 has a mounting position 31. The foot pad 4 has a slot 41 and a locking block 42 located within the slot 41. The locking block 42 is adapted to the mounting position 31. When the foot pad 4 is installed on the support leg 3, the support leg 3 is engaged in the slot 41, and the locking block 42 is engaged in the mounting position 31. The foot pad 4 increases the contact area with the gas stove panel, thereby reducing the pressure exerted on the gas stove panel by the stove rack and cookware. Furthermore, by appropriately selecting the material of the foot pad 4, its hardness can be reduced, thus minimizing wear on the gas stove panel. The connection between the foot pad 4 and the support leg 3 is achieved through a locking mechanism, allowing the foot pad 4 to be replaced promptly when excessively worn.
[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
