The energy-gathering ring has a cavity within it, which communicates with the outside world via a through-hole provided at the bottom of the energy-gathering ring. The energy-gathering ring provided by the present invention utilizes a hollow sheet metal structure, and its thermal conductivity is lower than that of a solid sheet metal energy-gathering ring of the same size, resulting in better insulation and reducing heat loss from high-temperature areas to low-temperature areas.

Description

Technical Field

[0001] The present invention belongs to the technical field of kitchen appliances, and in particular relates to an energy-gathering ring pot rack assembly and a gas stove. Background Art

[0002] Gas stoves are important kitchen appliances in people's daily lives. With the improvement of people's living standards, the performance requirements for gas stoves are becoming higher and higher, including high thermal efficiency, strong firepower, uniform heating, and low energy consumption.

[0003] Traditional energy-gathering rings are made of sheet metal and are used in conjunction with pot supports to improve the thermal efficiency of gas stoves. However, due to the good thermal conductivity of metal materials, during the cooking and heating process, a considerable amount of heat is still quickly dissipated from the high-temperature area to the low-temperature area due to the material problem of the energy-gathering ring.

[0004] In addition, the main function of the traditional pot support is to support the pot body and maintain the stability of the cooking pot. The energy-gathering ring pot support of household gas stoves on the market is relatively simple. The energy-gathering ring is basically a solid sheet metal plate and is fixed to the pot support by welding, so that the contact mode between the energy-gathering ring and the pot support is surface contact, which increases the heat conduction area and speeds up the heat conduction from the high-temperature zone to the pot support, resulting in rapid heat loss and affecting the heating efficiency.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide an energy-gathering ring pot rack assembly. The energy-gathering ring is made of hollow sheet metal. Since the interior of the energy-gathering ring is filled with air with a low thermal conductivity coefficient, the heat transfer from the upper high-temperature zone to the lower low-temperature zone can be reduced; at the same time, the pot rack support legs provided by the present invention adopt a raised setting on the contact surface with the energy-gathering ring, changing the surface contact to point contact, further reducing heat loss.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0008] The present invention provides an energy-gathering ring pot rack assembly, comprising an energy-gathering ring 1 coaxially arranged with a gas stove head, wherein a cavity 11 is provided inside the energy-gathering ring 1, and the cavity 11 communicates with the outside through a through hole 12 provided at the bottom of the energy-gathering ring 1.

[0009] The above solution uses a hollow sheet metal energy-gathering ring. Since the cavity is connected to the outside world through a through hole, a ring structure is formed with air, which has a weaker thermal conductivity, as the insulation layer. Compared with a solid sheet metal energy-gathering ring of the same size, this energy-gathering ring with a mixed hollow insulation layer has a better insulation effect, reducing the heat loss from the high-temperature area to the low-temperature area. Under the same conditions, the temperature of the high-temperature area of ​​the hollow sheet metal energy-gathering ring pot rack will be higher, making the combustion more complete and the thermal efficiency higher. In addition, during the operation of the gas stove, hot air will flow into or out of the energy-gathering ring through the through hole, which plays a role in balancing the pressure inside and outside the energy-gathering ring, protecting the structure and extending the service life of the energy-gathering ring.

[0010] A further solution of the present invention is: a plurality of through holes 12 facing the center of the energy focusing ring 1 are provided at the bottom of the energy focusing ring 1 , and the through holes 12 are connected by the cavity 11 ; preferably, adjacent through holes 12 are connected via a single cavity 11 .

[0011] In the above solution, the gas stove head and the energy-gathering ring are coaxially arranged. Therefore, the stove head is located inside the energy-gathering ring. Positioning the through-hole toward the stove head further enhances the circulation of hot air within and outside the energy-gathering ring cavity, preventing heat loss to low-temperature areas or the exterior. In the present invention, multiple, non-interconnected cavities can be formed within the energy-gathering ring, each connected by adjacent through-holes, ensuring that the hot air generated by the gas stove is evenly distributed within the insulation ring.

[0012] A further solution of the present invention is that the interior of the energy focusing ring 1 is filled with the cavities 11 , and the through holes 12 are connected via the same cavity 11 .

[0013] In the above scheme, a cavity is formed inside the energy-gathering ring, and the cavity is filled with the interior of the heat-insulating ring and is connected to the outside through a through hole at the bottom; since the cavity is fully distributed inside the heat-insulating ring, a large amount of hot air can be introduced into the energy-gathering ring when the gas stove is working, which greatly improves the heat insulation effect while also allowing the heat of the air circulating inside the energy-gathering ring to be absorbed by the sheet metal material, thereby improving the thermal efficiency of the gas stove.

[0014] A further solution of the present invention is: the energy focusing ring 1 includes an outer surface 14 and an inner surface 13 spaced apart in its axial and radial directions, the outer surface 14 and the inner surface 13 are respectively connected at their respective top and bottom ends to form the outer edge and inner edge of the energy focusing ring 1, and the through hole 12 is provided on the inner edge; the space between the outer surface 14 and the inner surface 13 constitutes the cavity 11.

[0015] A further solution of the present invention is that the bottom end of the outer surface 14 is lower than the bottom end of the inner surface 13 in the axial direction of the energy focusing ring 1, and the bottom end of the outer surface 14 and the bottom end of the inner surface 13 are equidistant from the center of the energy focusing ring 1, so that the through hole 12 provided on the inner edge is arranged toward the energy focusing center.

[0016] In the above solution, the energy-gathering ring has a trumpet-shaped structure, with its large opening facing upwards corresponding to the outer edge and its small opening facing downwards corresponding to the inner edge. The outer and inner surfaces of the energy-gathering ring are spaced apart by a certain distance in both the axial and radial directions, so that the layer between the outer and inner surfaces of the energy-gathering ring forms the cavity. The cavity wall is the inner sidewall of the outer and inner surfaces.

[0017] A further solution of the present invention is: an air guide groove is provided on the cavity wall of the cavity 11, and the air guide groove extends from the top of the cavity wall to the through hole 12; preferably, an air guide groove connecting two adjacent through holes 12 is provided on the cavity wall of the cavity 11, and the air guide groove is arc-shaped when close to the top of the cavity wall.

[0018] In the above scheme, since the hot air has to pass through the through hole to enter and exit the energy focusing ring, and the narrow cavity and the trumpet-shaped energy focusing ring hinder the circulation of air, an air guide groove is provided on the cavity wall, that is, the inner wall of the outer surface and inner surface of the energy focusing ring. The air guide groove is a linear groove body, extending from the top of the cavity wall to the through hole at the bottom, or connecting adjacent through holes in an arc shape to increase the circulation speed of the hot air in the energy focusing ring cavity.

[0019] A further solution of the present invention is: it also includes a pot rack 2 coaxially arranged with the energy focusing ring 1, the pot rack 2 includes a plurality of vertically arranged legs 21, and also includes a connecting ring 22 connected to the bottom of each leg 21, the legs 21 are partially passed through the energy focusing ring 1, and a plurality of protrusions 24 are provided on the contact surface between the legs 21 and the energy focusing ring 1.

[0020] In the above scheme, different from the scheme in the prior art in which the support leg and the energy focusing ring are integrally formed, the present invention sets part of the support leg through the annular surface of the energy focusing ring, and sets a number of protrusions on the contact surface of the support leg and the energy focusing ring. The protrusions can be selected from convex points or wavy lines. Under the premise of ensuring stable insertion, the contact area between the support leg and the energy focusing ring is reduced, preventing heat from being transferred to the pot rack support leg through the energy focusing ring, thereby avoiding heat loss.

[0021] In the above scheme, the theoretical formula of heat transfer is: Φ=A*λ*(t w1 -t w2 ) / δ, where Ф is the heat transferred per unit time, in W; A is the heat transfer area, in m 2 ;λ is the thermal conductivity, unit is W / (m·K); t w1 and t w2 is the temperature of the object undergoing heat transfer, measured in Kelvin; δ is the distance in the heat transfer direction, measured in meters. The hollow energy-focusing ring employed in this invention effectively reduces the thermal conductivity λ. The point contact protrusions provided at the contact points between the legs and the energy-focusing ring effectively reduce the heat transfer area A, thereby minimizing heat loss.

[0022] A further solution of the present invention is: a plurality of hollow portions 26 divided by positioning columns 23 are provided in the middle part of the support leg 21, and a plurality of positioning holes 15 are provided along the radial direction of the energy focusing ring 1. The positioning columns 23 are correspondingly inserted into the positioning holes 15, and the positioning columns 23 are provided with a plurality of protrusions 24 on the contact surface with the positioning holes 15, and the hollow portions 26 are provided with a plurality of protrusions 24 on the contact surface with the energy focusing ring 1; preferably, the protrusions 24 are provided on the support leg 21.

[0023] In the above-mentioned solution, the positioning holes are provided through the inner and outer surfaces of the energy focusing ring, and the positioning holes are provided with a tubular inner wall connecting the inner and outer surfaces to ensure the airtightness of the positioning holes and prevent hot air from escaping from the positioning holes. The support legs are provided with a plurality of hollow portions in the middle, each of which is divided by a positioning post. When the positioning post is inserted into the positioning hole, the side of the positioning post away from the center of the energy focusing ring contacts the inner wall of the positioning hole. A protrusion can be provided on this contact surface to reduce the contact area between the two. At the same time, the bottom of the hollow portion corresponds to the outer surface of the energy focusing ring. Specifically, the hollow portion corresponds to the outer surface of the energy focusing ring between the positioning holes. Therefore, a protrusion is also provided on the contact surface between the hollow portion and the outer surface of the energy focusing ring to reduce the contact area and thus prevent heat loss. Due to the difficulty in molding the energy focusing ring, it is preferred to provide the protrusions on the base surface of the energy focusing ring with the positioning post and the hollow portion.

[0024] A further solution of the present invention is: the support leg 21 is spliced ​​together by a horizontal extension portion 25 provided on its upper part and a vertical connection portion 27 connected to the connecting ring 22, and the bottom surface of the horizontal extension portion 25 and the top surface of the vertical connection portion 27 are respectively provided with columnar structures, so that the positioning column 23 is formed after splicing, and each horizontal extension portion 25 is in the same plane and extends toward the central axis of the energy focusing ring 1.

[0025] In the above scheme, since the support leg and the energy-focusing ring utilize point contact, and the hollow portion is a closed structure, the support leg is formed by splicing to achieve this structure. The support leg comprises an upper horizontal extension and a lower vertical connection, each of which has a corresponding columnar structure on the spliced ​​surface. When spliced ​​together, these two components form the positioning column, while the gaps between the positioning columns form the closed hollow portion. The splicing can be accomplished by providing corresponding connecting structures on the contact surfaces of the corresponding columnar structures of the horizontal extension and vertical connection, or by welding the contact surfaces of the corresponding columnar structures to form the support leg. The horizontal extension 25 extends radially inward from the pot stand 2, forming a support surface for the pot body. The horizontal extension 25 can also extend radially outward from the pot stand 2 to accommodate larger cooking pots.

[0026] A further solution of the present invention is that the energy-gathering ring 1 gradually tilts downward in an arc from the outer edge to the inner edge, forming an outwardly convex and curved annular surface.

[0027] The present invention also provides a gas stove, which includes a fire cover seat, an outer ring fire cover and an inner ring fire cover, which are coaxially arranged with the gas stove head and stacked in sequence from bottom to top. The gas stove also includes the energy-gathering ring pot rack assembly as described above, which includes an energy-gathering ring plugged into the pot rack. The assembly surrounds the fire cover seat and is coaxially arranged with it.

[0028] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0029] 1. The energy-gathering ring pot rack assembly provided by the present invention uses a hollow sheet metal energy-gathering ring with air as the insulation layer, which has a relatively weak thermal conductivity. Compared with solid sheet metal energy-gathering rings of the same size, this energy-gathering ring with a hollow insulation layer has a better insulation effect, reducing the heat loss from the high-temperature area to the low-temperature area.

[0030] 2. In the energy-gathering ring pot stand assembly provided by the present invention, the legs and the energy-gathering ring adopt a point contact method. Compared with the existing one-piece energy-gathering ring pot stands, this effectively prevents heat from being transferred to the pot stand legs through the energy-gathering ring, thereby avoiding heat loss;

[0031] 3. The energy-gathering ring pot stand assembly provided by the present invention adopts a splicing method to form the pot stand support legs, which realizes a stable connection with the energy-gathering ring while ensuring point contact connection with the energy-gathering ring.

[0044] like Figures 1 to 5 As shown, the present invention provides an energy-gathering ring pot rack assembly, which adopts an energy-gathering ring made of hollow sheet metal. Since the interior of the energy-gathering ring is filled with air with a low thermal conductivity coefficient, the heat transfer from the upper high-temperature area to the lower low-temperature area can be reduced; at the same time, the pot rack support provided by the present invention is provided with a protrusion on the contact surface between the pot rack support leg and the energy-gathering ring, changing the surface contact to point contact, further reducing heat loss.

[0045] Example 1

[0046] In this embodiment, an energy-gathering ring pot rack assembly is provided, which includes an energy-gathering ring 1 coaxially arranged with a gas stove head. A cavity 11 is provided inside the energy-gathering ring 1, and the cavity 11 communicates with the outside through a through hole 12 provided at the bottom of the energy-gathering ring 1.

[0047] This embodiment utilizes a hollow sheet metal energy-gathering ring. Because the cavity is connected to the outside world via through-holes, this ring structure uses air, a relatively weak thermal conductor, as its insulation layer. Compared to a solid sheet metal energy-gathering ring of the same size, this ring with a hollow insulation layer offers improved insulation, reducing heat loss from high-temperature areas to low-temperature areas. Furthermore, under the same conditions, the high-temperature area of ​​the pot holder in the hollow sheet metal energy-gathering ring will be higher, resulting in more complete combustion and higher thermal efficiency. Furthermore, during operation of the gas stove, hot air flows in and out of the energy-gathering ring through the through-holes, balancing the pressure inside and outside the ring, protecting the structure and extending its service life.

[0048] In this embodiment, the bottom of the energy focusing ring 1 is provided with a plurality of through holes 12 facing the center of the energy focusing ring 1 , and the through holes 12 are connected by the cavity 11 ; preferably, adjacent through holes 12 are connected via a single cavity 11 .

[0049] In this embodiment, the gas stove head and the energy-focusing ring are coaxially arranged. Thus, the stove head is located inside the energy-focusing ring. Positioning the through-holes toward the stove head further enhances the circulation of hot air within and outside the energy-focusing ring cavity, preventing heat loss to low-temperature areas or the exterior. In the present invention, multiple, non-interconnected cavities can be formed within the energy-focusing ring, each connected by adjacent through-holes, ensuring that the hot air generated by the gas stove is evenly distributed within the insulation ring.

[0050] In this embodiment, the energy gathering ring 1 includes an outer surface 14 and an inner surface 13 which are spaced apart in the axial and radial directions. The outer surface 14 and the inner surface 13 are connected at their respective top and bottom ends to form the outer edge and inner edge of the energy gathering ring 1, and the through hole 12 is provided on the inner edge; the space between the outer surface 14 and the inner surface 13 constitutes the cavity 11.

[0051] In this embodiment, the bottom end of the outer surface 14 is lower than the bottom end of the inner surface 13 in the axial direction of the energy focusing ring 1, and the bottom end of the outer surface 14 and the bottom end of the inner surface 13 are equidistant from the center of the energy focusing ring 1, so that the through hole 12 provided on the inner edge is arranged toward the energy focusing center.

[0052] In this embodiment, the energy-gathering ring has a trumpet-shaped structure, with a large opening pointing upwards corresponding to the outer edge and a small opening pointing downwards corresponding to the inner edge. The outer and inner surfaces of the energy-gathering ring are spaced apart by a certain distance in both the axial and radial directions, so that the layer between the outer and inner surfaces of the energy-gathering ring forms the cavity. The cavity wall is the inner sidewall of the outer and inner surfaces.

[0053] In this embodiment, a pot rack 2 is further included which is coaxially arranged with the energy focusing ring 1. The pot rack 2 includes a plurality of vertically arranged legs 21 and a connecting ring 22 connected to the bottom of each leg 21. Part of the legs 21 are passed through the energy focusing ring 1. A plurality of protrusions 24 are provided on the contact surface between the legs 21 and the energy focusing ring 1.

[0054] In this embodiment, unlike the solution in the prior art in which the support leg and the energy focusing ring are integrally formed, the present invention sets part of the support leg through the annular surface of the energy focusing ring, and sets a number of protrusions on the contact surface of the support leg and the energy focusing ring. The protrusions can be selected from convex points or wavy lines. Under the premise of ensuring stable insertion, the contact area between the support leg and the energy focusing ring is reduced, preventing heat from being transferred to the pot rack support leg through the energy focusing ring, thereby avoiding heat loss.

[0055] In this embodiment, the theoretical formula for heat transfer is: Φ=A*λ*(t w1 -t w2 ) / δ, where Ф is the heat transferred per unit time, in W; A is the heat transfer area, in m 2 ;λ is the thermal conductivity, unit is W / (m·K); t w1 and t w2 is the temperature of the object undergoing heat transfer, measured in Kelvin; δ is the distance in the heat transfer direction, measured in meters. The hollow energy-focusing ring employed in this invention effectively reduces the thermal conductivity λ. The point contact protrusions provided at the contact points between the legs and the energy-focusing ring effectively reduce the heat transfer area A, thereby minimizing heat loss.

[0056] In this embodiment, the energy focusing ring 1 gradually tilts downward in an arc from the outer edge to the inner edge, forming an outwardly convex and curved ring surface.

[0057] Example 2

[0058] The difference between this embodiment and embodiment 1 is that:

[0059] In this embodiment, the middle part of the support leg 21 is provided with a plurality of hollow portions 26 divided by positioning columns 23, and a plurality of positioning holes 15 are provided along the radial direction of the energy focusing ring 1. The positioning columns 23 are correspondingly inserted into the positioning holes 15, and the positioning columns 23 are provided with a plurality of protrusions 24 on the contact surface with the positioning holes 15. The hollow portions 26 are provided with a plurality of protrusions 24 on the contact surface with the energy focusing ring 1; preferably, the protrusions 24 are provided on the support leg 21.

[0060] In this embodiment, the positioning holes are provided through the inner and outer surfaces of the energy focusing ring, and the positioning holes are provided with tubular inner walls connecting the inner and outer surfaces to ensure airtightness and prevent hot air from escaping through the positioning holes. The legs are provided with a plurality of hollow sections in the middle, divided by positioning posts. When the positioning posts are inserted into the positioning holes, the side of the positioning posts away from the center of the energy focusing ring contacts the inner wall of the positioning holes. A protrusion may be provided on this contact surface to reduce the contact area between the two. Simultaneously, the bottom of the hollow sections supports the outer surface of the energy focusing ring. Specifically, the hollow sections support the outer surface of the energy focusing ring between the positioning holes. Therefore, a protrusion is also provided on the contact surface between the hollow sections and the outer surface of the energy focusing ring to reduce the contact area and thus prevent heat loss. Due to the difficulty in molding the energy focusing ring, it is preferred to provide the protrusions on the base surfaces of the positioning posts and the hollow sections, respectively, with the energy focusing ring.

[0061] In this embodiment, the support leg 21 is composed of a horizontal extension portion 25 provided on the upper part thereof and a vertical connection portion 27 connected to the connecting ring 22. The bottom surface of the horizontal extension portion 25 and the top surface of the vertical connection portion 27 are respectively provided with columnar structures, so that the positioning column 23 is formed after splicing. The horizontal extension portions 25 are in the same plane and are all extended toward the central axis of the energy focusing ring 1.

[0062] In this embodiment, since the support leg and the energy-focusing ring utilize point contact, and the hollow portion is a closed structure, the support leg is formed by splicing to achieve this structure. The support leg comprises an upper horizontal extension and a lower vertical connection. Both are provided with corresponding columnar structures on the joining surface, forming the positioning posts when spliced ​​together. The gaps between the positioning posts also form the closed hollow portion. The splicing can be accomplished by providing corresponding connecting structures on the contact surfaces of the corresponding columnar structures of the horizontal extension and vertical connection, or by welding the contact surfaces of the corresponding columnar structures to form the support leg. The horizontal extension 25 extends radially inward from the pot stand 2, forming a support surface for the pot body. The horizontal extension 25 can also extend radially outward from the pot stand 2 to accommodate larger cooking pots.

[0063] Other implementations of this embodiment are the same as those of Example 1.

[0064] Example 3

[0065] The difference between this embodiment and embodiment 1 is that:

[0066] In this embodiment, the interior of the energy focusing ring 1 is filled with the cavities 11 , and the through holes 12 are connected via the same cavity 11 .

[0067] In this embodiment, a cavity is formed inside the energy-gathering ring, and the cavity is filled with the interior of the heat-insulating ring and is connected to the outside through a through hole at the bottom. Since the cavity is fully distributed inside the heat-insulating ring, a large amount of hot air can be introduced into the energy-gathering ring when the gas stove is working, which greatly improves the heat insulation effect. At the same time, the heat of the air circulating inside the energy-gathering ring is absorbed by the sheet metal material, thereby improving the thermal efficiency of the high-temperature zone.

[0068] Other implementations of this embodiment are the same as those of Example 1.

[0069] Example 4

[0070] The difference between this embodiment and embodiment 1 or 2 is that:

[0071] In this embodiment, an air guide groove is provided on the cavity wall of the cavity 11, and the air guide groove extends from the top of the cavity wall to the through hole 12; preferably, an air guide groove connecting two adjacent through holes 12 is provided on the cavity wall of the cavity 11, and the air guide groove is arc-shaped when close to the top of the cavity wall.

[0072] In this embodiment, since the hot air has to pass through the through hole to enter and exit the energy focusing ring, and the narrow cavity and the trumpet-shaped energy focusing ring hinder the circulation of air, an air guide groove is provided on the cavity wall, that is, the inner wall of the outer surface and inner surface of the energy focusing ring. The air guide groove is a linear groove body, extending from the top of the cavity wall to the through hole at the bottom, or connecting adjacent through holes in an arc shape to increase the circulation speed of the hot air in the energy focusing ring cavity.

[0073] Other implementations of this embodiment are the same as those of Embodiment 1 or 2.
