Description

Technical Field

[0001] This invention relates to the field of gas equipment technology, and in particular to a stove energy-concentrating ring bracket. Background Technology

[0002] A flame-concentrating ring bracket is a ring-shaped bracket used in gas stoves and installed on the outside of the burner. Its main functions include concentrating the flame, preventing heat loss, preventing the flame from being blown out by wind, maintaining stable combustion, and improving thermal efficiency. Most existing flame-concentrating ring brackets are made of a single layer of metal sheet. The heat energy emitted by the burner is directly radiated to the flame-concentrating ring bracket. The bracket heats up quickly and easily transfers heat to the stove below or the lower-temperature area on the outside, causing rapid heat loss and affecting heating efficiency. Summary of the Invention

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a stove energy-concentrating ring bracket, which, by setting up a heat insulation cavity and a ventilation channel, helps to reduce heat loss to the outside and improves the thermal efficiency of the stove.

[0004] According to an embodiment of the present invention, a stove energy-concentrating ring support includes support legs and an energy-concentrating ring assembly. The support legs are connected to the energy-concentrating ring assembly and are used to support cooking utensils. The energy-concentrating ring assembly has a ring-shaped structure. Multiple support legs are provided, and the multiple support legs are distributed at intervals around the axis of the energy-concentrating ring assembly. The energy-concentrating ring assembly includes an upper ring body and a lower ring body located below the upper ring body. A heat insulation cavity is provided between the upper ring body and the lower ring body. The heat insulation cavity is connected to a vent, and the heat insulation cavity can communicate with the outside atmosphere through the vent.

[0005] The stove energy-concentrating ring bracket according to the embodiments of the present invention has at least the following beneficial effects: In use, the stove energy-concentrating ring bracket is sleeved on the outside of the stove burner, and the cooking utensils are placed on multiple support legs to support them. During heating, the heat energy emitted by the burner is directly radiated to the upper ring. Since a heat insulation cavity is provided between the upper and lower rings, the air in the heat insulation cavity has relatively weak thermal conductivity, which helps to reduce heat transfer to the lower ring and thus helps to reduce heat loss to the outside. Under the same conditions, the temperature below the cooking utensils is higher, which helps to improve the thermal efficiency of the stove. The heat insulation cavity is connected to the outside atmosphere through a vent, allowing the air in the heat insulation cavity to circulate. This helps to maintain the air pressure balance between the heat insulation cavity and the outside atmosphere, reducing the possibility of deformation due to thermal expansion and facilitating use.

[0006] According to some embodiments of the present invention, a plurality of ventilation channels are provided on both the inner and outer sides of the energy-concentrating ring assembly, with the opening side of the ventilation channel communicating with the external atmosphere facing downward.

[0007] According to some embodiments of the present invention, the inner and outer sides of the upper ring body are provided with downwardly extending first flange portions, and the inner and outer sides of the lower ring body are provided with downwardly extending second flange portions. The second flange portion is provided with a plurality of recessed positions, and the second flange portion abuts against the first flange portion, so that the ventilation channel is formed between the second flange portion and the first flange portion at the recessed position.

[0008] According to some embodiments of the present invention, the upper ring body is a one-piece stamped structure, and the lower ring body is a one-piece stamped structure.

[0009] According to some embodiments of the present invention, the upper ring body has a first annular surface and a second annular surface, the second annular surface being located inside the first annular surface, the first annular surface gradually sloping downward from the outer edge to the inner edge, the second annular surface gradually sloping upward from the outer edge to the inner edge, and an arc-shaped transition surface being provided between the inner edge of the first annular surface and the outer edge of the second annular surface and engaging with the arc-shaped transition surface.

[0010] According to some embodiments of the present invention, the support member is inserted into the energy-concentrating ring assembly and has an abutting portion that abuts against the upper ring body.

[0011] According to some embodiments of the present invention, the upper side of the support member is higher than the upper side of the upper ring.

[0012] According to some embodiments of the present invention, both the upper ring and the lower ring are provided with insertion holes for the support member to pass through, and the lower end of the support member extends from the insertion hole on the lower ring to the bottom of the lower ring.

[0013] According to some embodiments of the present invention, the lower end of the support leg is fitted with a foot sleeve.

[0028] Reference Figure 1 , Figure 2 and Figure 4 A stove energy-concentrating ring support includes support legs 100 and an energy-concentrating ring assembly 200. The support legs 100 are connected to the energy-concentrating ring assembly 200 and are used to support cooking utensils. The energy-concentrating ring assembly 200 has a ring-shaped structure. Multiple support legs 100 are provided and are distributed at intervals around the axis of the energy-concentrating ring assembly 200. The energy-concentrating ring assembly 200 includes an upper ring body 210 and a lower ring body 220 located below the upper ring body 210. A heat insulation cavity 201 is provided between the upper ring body 210 and the lower ring body 220. The heat insulation cavity 201 is connected to a vent 202 and can communicate with the outside atmosphere through the vent 202.

[0029] Understandably, such as Figure 1 , Figure 2 and Figure 4 As shown, the energy-concentrating ring assembly 200 has a circular ring structure, with the upper ring 210 stacked on the lower ring 220. There are four support members 100, which are evenly distributed around the axis of the energy-concentrating ring assembly 200. In use, the stove's energy-concentrating ring bracket is fitted onto the outside of the stove's burner, and the cooking utensils are placed on the multiple support legs 100 for support. During heating, the heat energy emitted by the burner is directly radiated to the upper ring 210. The upper ring 210 and the lower ring 220 are separate structures, and an insulation cavity 201 is provided between the upper ring 210 and the lower ring 220. The air in the insulation cavity 201 has relatively weak thermal conductivity, which helps reduce heat transfer to the lower ring 220, thereby reducing heat loss to the outside. Under the same conditions, the temperature below the cooking utensils is higher, which helps improve the stove's thermal efficiency. The insulation cavity 201 is connected to the outside atmosphere through the vent 202, allowing air to circulate within it. This helps maintain air pressure balance between the insulation cavity 201 and the outside atmosphere, reducing the possibility of deformation due to thermal expansion and facilitating use.

[0030] In practical applications, the support member 100 can also be provided with three, six or more. The specific structure of the upper ring 210 and the lower ring 220 can be set according to the actual use needs, which will not be described in detail here, but will be explained in detail below.

[0031] In some embodiments, the energy-concentrating ring assembly 200 is provided with a plurality of ventilation channels 202 on both the inner and outer sides of the ring, with the opening side of the ventilation channel 202 communicating with the external atmosphere facing downward.

[0032] Understandably, such as Figure 2 and Figure 4As shown, the energy-concentrating ring assembly 200 has multiple vents 202 on both the inner and outer sides of the ring to facilitate airflow within and outside the insulation cavity 201. The openings of each vent 202 that connect to the external atmosphere face downwards to prevent foreign objects from entering the insulation cavity 201 through the vents 202. This is particularly beneficial for liquids such as water, reducing the likelihood of water entering through the vents 202 and accumulating in the insulation cavity 201, thus facilitating use. In practical applications, the vents 202 can also be located only on the inner or outer side of the energy-concentrating ring assembly 200, and the orientation of their openings can be varied according to actual usage requirements.

[0033] In some embodiments, the inner and outer sides of the upper ring body 210 are provided with downwardly extending first flange portions 211, and the inner and outer sides of the lower ring body 220 are provided with downwardly extending second flange portions 221. The second flange portions 221 are provided with a plurality of recessed positions 222, and the second flange portions 221 abut against the first flange portions 211 so that a ventilation channel 202 is formed between the second flange portions 221 and the first flange portions 211 at the recessed positions 222.

[0034] Understandably, such as Figure 2 , Figure 3 and Figure 4 As shown, the upper ring 210 has a first flange 211 extending downward on both the inner and outer sides, and the lower ring 220 has a second flange 221 extending downward on both the inner and outer sides. Multiple recesses 222 are evenly spaced along the circumference of the second flanges 221. The second flanges 221 abut against the inner side of the first flanges 211, so that ventilation channels 202 are formed at the recesses 222. The above structure is simple and reasonable, which facilitates the formation and setting of ventilation channels 202, and helps to reduce the contact area between the upper ring 210 and the lower ring 220, reduce contact heat transfer, further reduce heat transfer to the lower ring 220, and facilitate use.

[0035] In practical applications, in addition to the above structure, the ventilation duct 202 can also be a hole located on the lower side of the lower ring 220 or a hole located on the outer edge of the upper ring 210. The specific configuration can be determined according to the actual usage requirements.

[0036] In some embodiments, the upper ring 210 and the lower ring 220 are both integrally stamped structures. It is understood that by making both the upper ring 210 and the lower ring 220 integrally stamped structures, manufacturing is facilitated, and it is easier to form the flanged structure and the recessed position 222 through stamping. In practical applications, the upper ring 210 and the lower ring 220 can also be integrally cast structures, depending on the specific application requirements.

[0037] In some embodiments, the upper ring body 210 has a first annular surface 212 and a second annular surface 214. The second annular surface 214 is located inside the first annular surface 212. The first annular surface 212 gradually slopes downward from the outer edge to the inner edge, and the second annular surface 214 gradually slopes upward from the outer edge to the inner edge. An arc-shaped transition surface 213 is provided between the inner edge of the first annular surface 212 and the outer edge of the second annular surface 214, and they are connected through the arc-shaped transition surface 213.

[0038] Understandably, such as Figure 1 and Figure 4 As shown, the second annular surface 214 is located inside the first annular surface 212. The inner edge of the first annular surface 212 and the outer edge of the second annular surface 214 are connected by an arc-shaped transition surface 213. The first annular surface 212 gradually slopes downward from its outer edge to its inner edge, while the second annular surface 214 gradually slopes upward from its outer edge to its inner edge. The gas output from the burner holes of the outer burner cap is sprayed onto the first annular surface 212 of the upper ring body 210. Part of the gas is gathered and burned upward through the first annular surface 212, while part is guided downward through the arc-shaped transition surface 213 to the second annular surface 214. Under the upward guiding action of the second annular surface 214, the gas collides with the gas just discharged from the burner holes, reducing the gas velocity and increasing the residence time of the gas in the area above the upper ring body 210. This allows the gas to undergo secondary combustion in this area, which is beneficial to improving the heating efficiency of the stove. In practical applications, the specific structure of the upper ring body 210 can be changed according to actual usage needs.

[0039] In some embodiments, the support member 100 is inserted into the energy-concentrating ring assembly 200 and has an abutment portion 110 that abuts against the upper ring body 210. It is understood that, as Figure 1 , Figure 3 and Figure 4 As shown, the support member 100 has an abutment portion 110 on one side. The support member 100 is connected to the energy-concentrating ring assembly 200 by a plug-in connection. Its structure is simple and facilitates the installation and connection of the support member 100. The abutment portion 110 abuts against the upper ring body 210 to facilitate the positioning and fixation of the support member 100, making it convenient to use. In practical applications, the specific structure of the support member 100 can be changed according to the actual needs of use. For example, it can also be connected to the energy-concentrating ring assembly 200 by means of screwing, snap-fitting, or welding.

[0040] In some embodiments, the upper side of the support leg 100 is higher than the upper side of the upper ring 210. It is understood that, as Figure 1 and Figure 4As shown, by setting the upper side of the support leg 100 higher than the upper side of the upper ring 210, when the cooking appliance is placed on the upper side of the support leg 100, a ventilation gap can be formed between the lower side of the cooking appliance and the upper side of the upper ring 210, facilitating the intake of air and promoting complete combustion of the gas, thus making it easier to use. In practical applications, the height difference between the upper side of the support leg 100 and the upper side of the upper ring 210 can be set according to actual usage needs and is not limited here.

[0041] In some embodiments, both the upper ring 210 and the lower ring 220 are provided with insertion holes 203 for the support member 100 to pass through, and the lower end of the support member 100 extends from the insertion hole 203 on the lower ring 220 to the bottom of the lower ring 220.

[0042] Understandably, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, both the upper ring 210 and the lower ring 220 are provided with insertion holes 203. During installation, the support member 100 passes through the insertion holes 203 on the upper ring 210 and the lower ring 220 from top to bottom, which facilitates the insertion and fixing of the support member 100. When the stove energy-concentrating ring bracket is placed on the stove, since the lower end of the support member 100 extends from the insertion hole 203 on the lower ring 220 to the bottom of the lower ring 220, a ventilation gap is formed between the lower side of the lower ring 220 and the stove surface, which facilitates the replenishment of air, promotes the complete combustion of gas, and is convenient to use.

[0043] In practical applications, the support 100 can also be just the upper ring 210. The air supply to the inner side of the energy-concentrating ring assembly 200 can also be achieved through the vent 202 or the vent gap on the upper side of the energy-concentrating ring assembly 200. The specific method can be changed according to the actual needs of use.

[0044] In some embodiments, the lower end of the support leg 100 is fitted with a foot sleeve 120. It is understood that, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, by fitting a foot sleeve 120 onto the lower end of the support leg 100, the foot sleeve 120 can be made of plastic, rubber, or a metal material with poor thermal conductivity. This helps reduce heat conduction from the support leg 100 to the lower surface of the stove. Furthermore, the foot sleeve 120 also helps limit the upward movement of the support leg 100, improving its assembly stability. In practical applications, the specific structure of the foot sleeve 120 can be customized according to actual usage requirements.

[0045] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
