Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and more specifically, to an energy-concentrating pot rack with multi-layer energy-concentrating channels. Background Technology

[0002] In traditional cooking scenarios, ordinary pot supports have a single function, primarily supporting the cookware. When the burner is operating, high-temperature flue gas rises and diffuses rapidly, resulting in significant heat loss and low energy efficiency. Simultaneously, insufficient and unevenly distributed air supply leads to incomplete combustion, wasting fuel and producing more harmful gases, impacting the environment and the user's health. Although some existing pot supports have seen improvements, they still fall short in terms of energy concentration and optimized combustion, failing to meet the demands for energy conservation, emission reduction, and improved cooking efficiency. Utility Model Content

[0003] The purpose of this invention includes, for example, providing an energy-concentrating boiler rack with multi-layer energy-concentrating channels, which can achieve coupling and mixing of high-temperature flue gas and secondary air to improve thermal efficiency.

[0004] The embodiments of this utility model can be implemented as follows: In a first aspect, this utility model provides an energy-concentrating pot frame with multi-layer energy-concentrating channels, comprising: The ring body has at least two energy-concentrating channels, and the ring body encloses an energy-concentrating zone, which can accommodate the stove head. Along the radial direction of the ring, a plurality of energy-concentrating channels are arranged adjacent to each other in sequence, and adjacent energy-concentrating channels are interconnected through circulation ports; Each of the energy-concentrating channels is provided with a slot that communicates with the outside world; Furthermore, the height of the energy-concentrating channel located radially inside the ring is less than the height of the energy-concentrating channel located radially outside the ring.

[0005] This design features a multi-layered energy-concentrating pot rack. Adjacent energy-concentrating channels can concentrate flue gas, preheating the secondary air entering the channels and supplying pre-set secondary air to the burner. This achieves the coupling and mixing of high-temperature flue gas and secondary air, improving thermal efficiency. Simultaneously, the reduced height design at the lower end of the energy-concentrating channels, located radially inner to the ring, not only creates multiple independent heat-concentrating spaces, enhancing the energy-concentrating effect, but also effectively prevents air diffusion, allowing heat to be more concentrated on the bottom of the pot.

[0006] In an optional embodiment, the opening of the slot in the energy-concentrating channel located radially inside the ring body faces downwards. This allows the preheated air to move downwards and concentrate at the bottom of the cookware, ensuring that the burner receives preheated secondary air in a timely and efficient manner, thereby improving combustion efficiency.

[0007] In an optional embodiment, the slots of the energy-concentrating channels are all arranged along the axial direction of the ring body, and the opening directions of the slots of adjacent energy-concentrating channels are opposite. This allows adjacent energy-concentrating channels to form an S-shaped reciprocating air passage, increasing the heat exchange area.

[0008] In an optional embodiment, when the slot of the energy-concentrating channel faces upward, a through overflow hole is provided at the bottom of the energy-concentrating channel. Such an overflow hole can drain accumulated water in a timely manner, ensuring the normal use of the boiler rack.

[0009] In an optional embodiment, between adjacent energy-concentrating channels, at least one circulation port is provided on the side wall of one energy-concentrating channel near another; in each energy-concentrating channel, multiple circulation ports are arranged sequentially along the axial direction of the ring body. This allows secondary air to flow through the circulation ports between the various energy-concentrating channels, be heated by the multiple layers of energy-concentrating channels to raise the air temperature, and then flow to the burner, improving combustion efficiency.

[0010] In an optional embodiment, a guide vane is provided at the edge of the air circulation port, extending away from the center of the annulus. This guide vane directs the air passing through the air circulation port, ensuring that the air flows evenly along a predetermined path between the energy-concentrating channels, guaranteeing uniform air distribution and further improving combustion efficiency.

[0011] In an optional embodiment, the guide vane maintains an angle of 25-40° with the sidewall of the energy-concentrating channel. This allows the guide vane to direct airflow along the wall, reducing dead zones.

[0012] In an optional embodiment, at least one air inlet is provided on the outer wall of the energy-concentrating channel located radially outward of the ring body; a plurality of air inlets are arranged sequentially along the axial direction of the ring body. This placement of the air inlets at the outermost layer of the ring body allows for the introduction of secondary air, providing sufficient oxygen for combustion and promoting more complete fuel combustion.

[0013] In an optional embodiment, along the radial direction of the annulus, the recirculation port and the air inlet are staggered between adjacent energy-concentrating channels. This results in a longitudinally staggered design of the air inlet and the air recirculation port, allowing secondary air to enter from the air inlet, flow through the recirculation port between the energy-concentrating channels, be heated by the multiple layers of energy-concentrating channels, increase the air temperature, and then flow from the energy-concentrating channels to the burner, thereby improving combustion efficiency.

[0014] In an optional embodiment, a plurality of foot plates are also included, which are disposed on the outer wall of the ring. The foot plates are used to securely support the cookware and ensure the stability of the cookware on the cookware rack.

[0015] The beneficial effects of this utility model embodiment include, for example: This design features a multi-layered energy-concentrating pot frame comprising a ring. The ring has at least two energy-concentrating channels, which collect the high-temperature flue gas generated by the burner, forming individual heat accumulation spaces. Adjacent energy-concentrating channels are interconnected via circulation ports, allowing air to move between them and facilitating the replenishment of secondary air to the burner. Each energy-concentrating channel has a slot connecting to the outside, serving as a passage for air to enter the corresponding channel. Thus, the slots, circulation ports, and energy-concentrating channels work together to form a secondary air replenishment path for preheating the air and delivering it to the burner, achieving the beneficial effect of heat concentration and improved thermal efficiency. Furthermore, the design of a decreasing height at the lower end of the energy-concentrating channels not only enhances the energy concentration effect but also effectively prevents air diffusion, allowing heat to be more concentrated on the bottom of the pot.

[0022] 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.

[0023] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0024] 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.

[0025] Please refer to Figure 1 , Figure 2 and Figure 3 This embodiment provides a condensing pot frame with multi-layer condensing channels, including a ring body 10; The ring body 10 has at least two energy-concentrating channels 100, and the ring body 10 encloses an energy-concentrating zone 101, which can accommodate the stove head; Along the radial direction of the ring 10, multiple energy-concentrating channels 100 are arranged adjacent to each other in sequence, and adjacent energy-concentrating channels 100 are connected to each other through circulation ports 200. Each energy-concentrating channel 100 is equipped with a slot 110 that connects to the outside world; Furthermore, the height of the energy-concentrating channel 100 located radially inside the ring 10 is less than the height of the energy-concentrating channel 100 located radially outside the ring 10.

[0026] The energy-concentrating cooker rack with multi-layered energy-concentrating channels in this design includes a ring body 10. The ring body 10 has at least two energy-concentrating channels 100, which collect the high-temperature flue gas generated by the burner, thus forming a separate heat accumulation space. Adjacent energy-concentrating channels 100 are interconnected through circulation ports 200, allowing air to move between adjacent channels and facilitating the replenishment of secondary air to the burner. Each energy-concentrating channel 100 is provided with a slot 110 communicating with the outside, serving as a channel for air to enter the corresponding energy-concentrating channel 100. Thus, the slot 110, circulation port 200, and energy-concentrating channels 100 work together to form a secondary air replenishment path for preheating and supplying air to the burner, achieving the beneficial effect of coupling and mixing high-temperature flue gas and secondary air to improve thermal efficiency. Simultaneously, the design of a decreasing height at the lower end of the energy-concentrating channels 100 not only enhances the energy-concentrating effect but also effectively prevents air diffusion, allowing heat to be more concentrated on the bottom of the cookware.

[0027] Please continue reading. Figure 1 , Figure 2 , Figure 3 and Figure 4 The image shows more structural details of the energy-concentrating pot frame with multiple energy-concentrating channels.

[0028] Furthermore, in this embodiment, the ring body 10 is annular, and each energy-concentrating channel 100 is a hollow ring concentrically arranged with the ring body 10. Optionally, the ring body 10 is formed by continuously bending a plate, with adjacent plates enclosing each other to form the energy-concentrating channel 100. The slot 110 is an opening at the top or bottom of the energy-concentrating channel 100, so that the energy-concentrating channel 100 forms a U-shape. In use, the burner is located at the center of the ring body 10.

[0029] It is not difficult to understand that in other embodiments of this utility model, the ring body 10 and the energy-concentrating channel 100 can also be rectangular, elliptical, or other shapes. The ring body 10 can be formed by welding, bonding, or other methods instead of bending the plate. This is just an example and is not limited to any specific form.

[0030] It should be noted that in this embodiment, the U-shaped groove of the energy-concentrating channel 100 has a depth h = 8–15 mm, a width d = 6–12 mm, and an interlayer spacing s = 2–4 mm. The bottoms of adjacent energy-concentrating channels 100 are arranged in a stepped manner: the bottom of the energy-concentrating channel 100 located on the radially inner side is higher than that of the adjacent energy-concentrating channel 100 located on the radially outer side, which is 5–10 mm higher, forming a labyrinthine water-blocking and wind-blocking wall to prevent lateral air diffusion.

[0031] As can also be seen from the figure, in an optional embodiment, the energy-concentrating pot rack further includes multiple foot pieces 20, which are disposed on the outer wall of the ring 10. The foot pieces 20 are used to firmly support the pot, ensuring the stability of the pot on the pot rack. The shape and size of the foot pieces 20 are designed according to actual usage needs, and can adapt to different sizes of pots, providing a reliable support base for the cooking process.

[0032] Please continue reading. Figures 1 to 3 In an optional embodiment, the slot 110 of the energy-concentrating channel 100 located radially inner to the annulus 10 faces downwards. This allows the preheated air to move downwards and concentrate at the bottom of the cookware, ensuring that the burner receives preheated secondary air in a timely and efficient manner, thereby improving combustion efficiency. The slot 110 of the energy-concentrating channel 100 on the inner side of the annulus 10 is used to spray preheated secondary air towards the burner.

[0033] It should be noted that in other embodiments of this utility model, the opening direction of the slot 110 of the energy-concentrating channel 100 located on the radial inner side of the ring 10 is arranged upward; furthermore, the opening of each energy-concentrating channel 100 can be upward or downward at the same time, as long as the energy-concentrating channel 100 can concentrate heat. This is just an example and is not limited in specific terms.

[0034] As can also be seen from the figure, in the optional embodiment, the slots 110 of the energy-concentrating channels 100 are all arranged along the axial direction of the ring body 10, and the opening directions of the slots 110 of adjacent energy-concentrating channels 100 are opposite. This allows adjacent energy-concentrating channels 100 to form an S-shaped reciprocating air passage, increasing the heat exchange area.

[0035] It is not difficult to understand that in other embodiments of this utility model, the opening direction of the slots 110 of adjacent energy-concentrating channels 100 can also be the same, as long as the energy-concentrating channels 100 can concentrate heat. This is just an example and is not limited to any specific example.

[0036] In an optional embodiment, when the slot 110 of the energy-concentrating channel 100 faces upward, a through overflow hole 120 is provided at the bottom of the energy-concentrating channel 100. Such an overflow hole 120 can drain accumulated water in a timely manner, ensuring the normal use of the boiler rack.

[0037] Furthermore, to prevent water accumulation inside the U-shaped upward-facing energy-concentrating channel 100, an overflow hole 120 is provided at the bottom of the energy-concentrating channel 100 to drain accumulated water in a timely manner and ensure the normal use of the boiler rack. An overflow hole 120 with a diameter of 1.5–2 mm is opened at the lowest point of each U-shaped groove, with the opening inclined outwards at 5°. This utilizes surface tension to create a siphon effect, thereby draining the water from the energy-concentrating channel 100. The outlet of the overflow hole 120 is concealed inside the boiler rack foot piece 20 to prevent direct flame blowing and to prevent "backfire at the orifice".

[0038] In an optional embodiment, between adjacent energy-concentrating channels 100, at least one circulation port 200 is provided on the side wall of one energy-concentrating channel 100 near another; in each energy-concentrating channel 100, multiple circulation ports 200 are arranged sequentially along the axial direction of the ring body 10. This allows secondary air to flow between the various energy-concentrating channels 100 through the circulation ports 200, and after being heated by multiple layers of energy-concentrating channels 100, the air temperature is increased, and then it flows to the burner, improving combustion efficiency.

[0039] In an optional embodiment, a guide vane 300 is provided at the edge of the circulation port 200, extending away from the center of the annular body 10. This allows the guide vane 300 to guide the air passing through the air circulation port 200, ensuring that the air flows evenly along a predetermined path between the energy-concentrating channels 100, guaranteeing uniform air distribution and further improving combustion efficiency. Furthermore, in this embodiment, the guide vane 300 is only located at the upper edge of the circulation port 200, and the guide vane 300 is angled upwards.

[0040] In an optional embodiment, the guide vane 300 maintains an angle of 25-40° with the sidewall of the energy-concentrating channel 100. This allows the guide vane 300 to guide airflow along the wall, reducing dead zones.

[0041] In an optional embodiment, at least one air inlet 400 is provided on the outer wall of the energy-concentrating channel 100 located radially outward of the annulus 10; multiple air inlets 400 are arranged sequentially along the axial direction of the annulus 10. This arrangement of the air inlets 400 at the outermost layer of the annulus 10 allows for the introduction of secondary air, providing sufficient oxygen for combustion and promoting more complete fuel combustion. Optionally, the air inlets 400 may be waist-shaped or louvered.

[0042] In an optional embodiment, along the radial direction of the annulus 10, the recirculation port 200 and the air inlet 400 are staggered between adjacent energy-concentrating channels 100. This results in a longitudinally staggered design between the air inlet 400 and the air recirculation port 200, so that after secondary air enters from the air inlet 400, it flows through the recirculation port 200 between the energy-concentrating channels 100. After being heated by the multiple layers of energy-concentrating channels 100, the air temperature rises, and then it flows from the energy-concentrating channels 100 to the burner, improving combustion efficiency.

[0043] When in use, the burner generates high-temperature flue gas, which fills the radially inner energy-concentrating channel 100. The heat from the high-temperature flue gas is conducted through the ring body 10 to the radially outer energy-concentrating channel 100.

[0044] Secondary air from the environment enters through air inlet 400, is preheated in the radially outer energy-concentrating channel 100, and then enters the radially inner energy-concentrating channel 100 through circulation port 200 to continue absorbing heat and raising its temperature. The heated secondary air then flows out through slot 110 of the radially inner energy-concentrating channel 100 and is sprayed towards the root of the outer ring flame hole of the burner, forming "hot air combustion aid". This process, using multiple energy-concentrating channels 100 with stepped height differences and longitudinally staggered air channels, ensures that the air can only exchange heat along the "S" shaped path along the wall, preventing short circuits. Rainwater or overflow is discharged immediately through overflow hole 120, preventing water accumulation in the cavity and preventing ice expansion in winter.

[0045] In summary, this utility model embodiment provides an energy-concentrating pot frame with multi-layer energy-concentrating channels, which has at least the following advantages: (1. Improve combustion efficiency: Secondary air is introduced through air inlet 400, and the air circulation port 200 and air guide plate 300 are used to make the air flow orderly and heated between each energy-concentrating channel 100, so as to provide the burner with air with higher temperature and uniform distribution, promote the complete combustion of fuel, reduce the emission of harmful gases, and improve combustion efficiency.

[0046] (2) Enhanced energy concentration effect: Multiple U-shaped bends form multiple energy concentration channels 100, which prolong the residence time of high-temperature flue gas, allowing the high-temperature flue gas to fully exchange heat with the cookware in the energy concentration channels 100, while preventing air diffusion, reducing heat loss, and significantly improving energy utilization.

[0047] (3) Prevent water accumulation and air diffusion: The design of the overflow hole 120 at the bottom of the energy-concentrating channel 100 can prevent water from accumulating inside the U-shaped upward energy-concentrating channel 100, ensuring the normal use of the pot rack; the design of the bottom height of the radial inner energy-concentrating channel 100 being higher than that of the radial outer energy-concentrating channel 100 effectively prevents air diffusion, making the heat more concentrated and further improving the energy-concentrating effect.

[0048] 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.
