Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and more specifically, to a turbulence-concentrating pot rack. Background Technology

[0002] In traditional cooking, pot racks primarily serve as a support for the cookware. However, with ordinary pot racks, the high-temperature flue gas generated by combustion rises rapidly and diffuses quickly into the surrounding environment, resulting in a significant loss of heat that cannot be effectively absorbed and utilized by the cookware. This leads to substantial energy waste and relatively low cooking efficiency. Although some existing pot racks have undergone certain improvements, they still fall short in guiding the high-temperature flue gas to form an effective vortex flow and prolonging the heat retention time to improve heat utilization, making it difficult to meet current demands for energy conservation, emission reduction, and improved cooking efficiency. Utility Model Content

[0003] The purpose of this invention includes, for example, providing a turbulent energy-concentrating boiler frame that enables high-temperature flue gas to form a longitudinally closed vortex ring at the center of the energy-concentrating ring, significantly extending the residence time and improving thermal efficiency.

[0004] The embodiments of this utility model can be implemented as follows: In a first aspect, this utility model provides a turbulence-concentrating energy pot frame, comprising: Energy-concentrating ring and multiple vortex sections; The energy-concentrating rings enclose a vortex cavity, which can accommodate the burner head; Multiple vortex sections are circumferentially arranged on the inner wall of the energy-concentrating ring; along the circumferential direction of the energy-concentrating ring, the multiple vortex sections are all inclined in the same direction; each vortex section extends along the axial direction of the energy-concentrating ring.

[0005] The turbulent energy-concentrating boiler rack has longitudinally arranged vortex sections on the inner wall of the energy-concentrating ring, which are distributed circumferentially. This causes the high-temperature flue gas to form a longitudinally closed vortex ring in the vortex cavity, which significantly prolongs the residence time, improves thermal efficiency, and reduces CO / NOx.

[0006] In an optional embodiment, the energy-concentrating ring has at least one energy-concentrating channel; each energy-concentrating channel has an opening at its bottom.

[0007] In an optional embodiment, the bottom of the vortex section is flush with the bottom of the energy-concentrating channel. This allows the heat generated by the burner to enter the inner cavity of the energy-concentrating channel in a timely manner, thereby facilitating the preheating of the secondary air in the energy-concentrating channel and guiding the preheated secondary air to flow towards the burner at the center of the energy-concentrating coil.

[0008] In an optional embodiment, the inner wall of the energy-concentrating ring is provided with multiple airflow ports, which penetrate the energy-concentrating channel inside the energy-concentrating ring and communicate with the center of the energy-concentrating ring. These airflow ports provide a specific outflow channel for the high-temperature flue gas, allowing it to pass through in an orderly manner during vortex flow, preventing disorderly diffusion of the flue gas, and creating conditions for further guidance and accumulation of the flue gas.

[0009] In an optional embodiment, the airflow inlet is located above the vortex section. This avoids interference between the airflow at the inlet and the airflow on the vortex section, thereby ensuring the smooth guidance of the high-temperature flue gas by the vortex section.

[0010] In an optional embodiment, the airflow inlet is located between two adjacent vortex sections along the circumferential direction of the energy-concentrating ring. This further ensures that the vortex sections and airflow inlets are staggered, making the airflow smoother and avoiding turbulence and other issues.

[0011] In an optional embodiment, a guide vane is provided along the upper edge of the airflow inlet, extending towards the center of the energy-concentrating ring. The guide vane has a specific shape and angle, which can guide the high-temperature flue gas passing through the high-temperature flue gas inlet, making the flue gas flow more precisely towards the bottom of the pot, further improving the flue gas recirculation effect, and ensuring that heat can be fully transferred to the pot.

[0012] In an optional embodiment, the guide vane is inclined to the inner wall of the energy-concentrating ring; the guide vane is folded upwards along the axial direction of the energy-concentrating ring. This allows the airflow to smoothly enter the energy-concentrating channel on the wall surface of the guide vane.

[0013] In an optional embodiment, each of the vortex sections includes a flat plate structure and an inclined plate structure, both of which are arranged along the axial direction of the energy-concentrating ring; the flat plate structure extends toward the radial direction of the energy-concentrating ring, and the inclined plate structure maintains an angle γ with the radial direction of the energy-concentrating ring.

[0014] In an optional embodiment, the angle γ between the inclined plate structure and the radial direction of the energy-concentrating ring is 20–35°.

[0015] In an optional embodiment, the energy-concentrating ring and multiple vortex sections are integrally formed. This simplifies the structure of the energy-concentrating pot frame, while reducing weight and improving thermal conductivity.

[0016] The beneficial effects of this utility model embodiment include, for example: The turbulent, energy-concentrating pot frame in this design includes an energy-concentrating ring and multiple vortex sections. When the burner is burning, the high-temperature flue gas encounters the longitudinally arranged vortex sections as it rises. Under the special guidance of these vortex sections, the high-temperature flue gas forms a vortex flow within the vortex cavity. This vortex flow alters the natural upward trajectory of the high-temperature flue gas, causing it to repeatedly swirl within a limited space. This significantly extends the residence time of the high-temperature flue gas within the pot frame, giving the pot more opportunities to absorb heat from the flue gas. This achieves vortex flow of the high-temperature flue gas within the vortex cavity, prolonging its residence time and making it easier for it to accumulate at the bottom of the pot during recirculation. This improves the pot's absorption of heat energy, reduces heat loss, and significantly enhances combustion efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0023] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0024] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0025] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0026] Please refer to Figure 1 , Figure 2 and Figure 3 This embodiment provides a turbulent energy-concentrating pot frame, including an energy-concentrating ring 100 and multiple vortex sections 200; The energy-concentrating ring 100 encloses and forms a vortex cavity 101, which can accommodate the burner head; Multiple vortex sections 200 are arranged circumferentially on the inner wall of the energy-concentrating ring 100; along the circumferential direction of the energy-concentrating ring 100, the multiple vortex sections 200 are all tilted in the same direction; each vortex section 200 extends along the axial direction of the energy-concentrating ring 100.

[0027] The energy-concentrating ring of the turbulent energy-concentrating pot rack in this design concentrates more heat at the bottom of the pot, improving heat transfer efficiency and reducing heat loss during the transfer process. When the burner is burning, the high-temperature flue gas encounters the longitudinally arranged vortex section 200 during its ascent. Under the special guidance of the vortex section, the high-temperature flue gas forms a vortex flow within the vortex cavity 101. This vortex flow pattern changes the natural upward trajectory of the high-temperature flue gas, causing it to swirl repeatedly within a limited space, greatly extending the residence time of the high-temperature flue gas within the pot rack, allowing the pot to absorb more heat from the flue gas. This achieves the formation of a vortex flow of high-temperature flue gas within the vortex cavity 101, prolonging the residence time of the high-temperature flue gas, and making it easier for the high-temperature flue gas to accumulate at the bottom of the pot during recirculation, thereby improving the pot's absorption of heat energy, reducing heat loss, and significantly improving combustion efficiency.

[0028] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 To learn more about the structural details of the turbulence-concentrating pot rack.

[0029] As shown in the figure, the energy-concentrating ring 100 has at least one energy-concentrating channel 110; each energy-concentrating channel 110 has an opening 111 at its bottom. Each energy-concentrating channel 110 forms a highly efficient heat-gathering area, concentrating more heat at the bottom of the cookware, improving heat transfer efficiency, and reducing heat loss during the transfer process. Furthermore, under the special guiding effect of the vortex section, the high-temperature flue gas forms a vortex flow between the energy-concentrating channel 110 and the burner of the stove.

[0030] In this embodiment, the energy-concentrating ring 100 is annular, and each energy-concentrating channel 110 is a hollow annular ring arranged concentrically with the energy-concentrating ring 100. Optionally, the energy-concentrating ring 100 is formed by continuously bending a plate, with adjacent plates enclosing each other to form the energy-concentrating channel 110. The opening 111 of the energy-concentrating channel 110 is an annular opening penetrating the bottom of the energy-concentrating ring 100, thus forming an inverted U-shaped structure. In use, the burner is located at the center of the energy-concentrating ring 100.

[0031] It is easy to understand that in other embodiments of this utility model, the energy-concentrating ring 100 and the energy-concentrating channel 110 can also be rectangular, elliptical, or other shapes. This is just an example and is not specifically limited.

[0032] It should be noted that when there are multiple energy-concentrating channels 110 in the energy-concentrating ring 100, the multiple energy-concentrating channels 110 are connected sequentially along the radial direction of the energy-concentrating ring 100 and are arranged concentrically. Interconnected airflow holes can also be provided between adjacent energy-concentrating channels 110.

[0033] Furthermore, in this embodiment, N=12–18 vortex sections 200 are evenly distributed along the circumference of the energy-concentrating ring 100. Each vortex section 200 has a sheet thickness of 0.8 mm, a height equal to the inner height H of the energy-concentrating channel 110, and a width W=6–10 mm.

[0034] Optionally, each vortex section 200 has multiple concave grooves with a depth of 0.3 mm on its surface. Adjacent grooves extend circumferentially along the energy-concentrating ring 100, with a groove spacing of 2 mm. These grooves are used to break up the boundary layer and induce longitudinal secondary flow.

[0035] In an optional embodiment, each vortex section 200 includes a flat plate structure 210 and an inclined plate structure 220, both arranged along the axial direction of the energy focusing ring 100; the flat plate structure 210 extends radially toward the energy focusing ring 100, and the inclined plate structure 220 maintains an angle γ with the radial direction of the energy focusing ring 100. In an optional embodiment, the angle γ between the inclined plate structure 220 and the radial direction of the energy focusing ring 100 is 20–35°.

[0036] As can also be seen from the diagram, the turbulence-concentrating pot support includes foot plates 400. Foot plates 400 are located on the radial outer wall of the energy-concentrating ring 100. Foot plates 400 are used to firmly support the pot, ensuring its stability on the pot support. Their shape and size are designed according to actual usage needs, adaptable to different sizes of pots, providing a reliable support base for the pot, and ensuring that the pot will not wobble or shift during cooking.

[0037] like Figure 2 and Figure 3 As shown, in an optional embodiment, the bottom of the vortex section 200 is flush with the bottom of the energy-concentrating channel 110. This allows the heat generated by the burner to enter the inner cavity of the energy-concentrating channel 110 in a timely manner, thereby facilitating the preheating of the secondary air in the energy-concentrating channel 110 and guiding the preheated secondary air to flow toward the burner at the center of the energy-concentrating ring 100.

[0038] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 As can also be seen from the figure, in an optional embodiment, multiple airflow ports 112 are provided on the inner wall of the energy-concentrating ring 100. The airflow ports 112 penetrate the energy-concentrating channel 110 inside the energy-concentrating ring 100 and are connected to the center of the energy-concentrating ring 100. The airflow port 112 provides a specific outflow channel for the high-temperature flue gas, allowing the high-temperature flue gas to pass through in an orderly manner during the vortex flow process, avoiding disorderly diffusion of the flue gas, and creating conditions for further guidance and accumulation of the flue gas.

[0039] In an optional embodiment, the airflow port 112 is located above the vortex section 200. This avoids interference between the airflow at the airflow port 112 and the airflow on the vortex section 200, thereby ensuring the smooth guidance of the high-temperature flue gas by the vortex section 200.

[0040] Furthermore, in an optional embodiment, the airflow port 112 is located between two adjacent vortex sections 200 along the circumferential direction of the energy-concentrating ring 100. This further ensures that the vortex sections 200 and the airflow port 112 are staggered, so that the airflow is smoother and turbulence is avoided.

[0041] As can also be seen from the figure, in an optional embodiment, a guide vane 300 is provided along the upper edge of the airflow inlet 112, extending towards the center of the energy-concentrating ring 100. The guide vane 300 has a specific shape and angle, which can guide the high-temperature flue gas passing through the high-temperature flue gas inlet 112 in a secondary manner, so that the flue gas flows more accurately towards the bottom of the pot, further improving the effect of flue gas recirculation and ensuring that heat can be fully transferred to the pot.

[0042] In an optional embodiment, the guide vane 300 is inclined to the inner wall of the energy-concentrating ring 100; the guide vane 300 is folded upwards along the axial direction of the energy-concentrating ring 100. This allows the airflow to smoothly enter the energy-concentrating channel 110 on the wall surface of the guide vane 300.

[0043] In an optional embodiment, the energy-concentrating ring 100 and the multiple vortex sections 200 are integrally formed. This simplifies the structure of the energy-concentrating pot frame, while reducing weight and improving thermal conductivity.

[0044] In summary, this utility model embodiment provides a turbulence-controlled energy-concentrating pot frame, which has at least the following advantages: (1) Improved energy efficiency: The longitudinally arranged vortex section 200 design enables the high-temperature flue gas to form a vortex flow between the energy-concentrating channel 110 and the burner, significantly extending the residence time of the high-temperature flue gas. At the same time, in conjunction with the synergistic effect of the high-temperature flue gas inlet 112, the flue gas guide plate 300 and the high-temperature flue gas guide plate, the flow path of the high-temperature flue gas is optimized, making it easier for the high-temperature flue gas to accumulate at the bottom of the pot during the recirculation. The pot can more fully absorb the heat in the flue gas, thereby greatly improving the combustion efficiency and reducing energy waste. Meanwhile, the burner flame generates tangential velocity when it encounters the inclined vortex section 200, which deteriorates the axial velocity; the high-temperature flue gas forms a "longitudinal vortex ring" (the flue gas rotates and moves up and down at the same time) in the cavity, forming a closed spiral path; the number of spiral turns is ≥2.5 turns, and the measured residence time is 1.8–2.0s, which is 50% longer than the horizontal vortex scheme.

[0045] (2) Innovative and practical structure: This energy-concentrating boiler rack has been innovatively improved on the basis of the traditional boiler rack structure. The longitudinally arranged vortex section 200, as well as the newly added high-temperature flue gas inlet 112, flue gas guide plate 300 and high-temperature flue gas guide plate, have a simple structure and can bring significant energy efficiency improvement.

[0046] (3) Three-dimensional turbulence enhancement: The longitudinal vortex causes the flue gas to continuously sweep across the bottom of the pot in the axial direction, and the radiation and convection heat transfer coefficients are increased by 30% at the same time.

[0047] (4) Temperature uniformity: The longitudinal exchange pulls the high-temperature flue gas in the center to the edge, and the temperature difference between the center and the edge of the pot bottom is reduced from 30℃ to ≤18℃.

[0048] (5) Emission reduction: The spiral path extends the combustion reaction time, reducing CO by 20% and NOx by 15%.

[0049] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
