Description

Technical Field

[0001] This invention relates to an energy-saving ring structure for gas stoves. Background Technology

[0002] On February 28, 2025, the State issued the "Minimum Allowable Values ​​of Energy Efficiency and Energy Efficiency Grades for Gas Stoves" (GB 30720-2025). Article 4 of this standard stipulates a new energy efficiency standard: starting March 1, 2026, the thermal efficiency of built-in / tabletop gas stoves for household use must reach 70% or higher to be rated as Grade 1 energy efficiency. This standard raises the energy efficiency threshold for the gas stove industry. This figure is significantly higher than the previous market average. It is understood that most gas stoves on the market currently have a thermal efficiency of around 65%, with very few products reaching 70%. Given the existing stove market, this urgently needs to be addressed in response to the national energy conservation and emission reduction policies. Summary of the Invention

[0003] This invention proposes an energy-saving ring structure for a gas stove, comprising a first combustion section and a second combustion section. The second combustion section is disposed within the inner ring of the first combustion section, and there is a gap between the first combustion section and the second combustion section. An energy-saving ring is disposed on one or more of the first combustion section, the second combustion section, or the gap. The energy-saving ring is provided with a reflective surface. During combustion, the energy-saving ring serves to insulate heat, reduce heat loss in the opposite direction, absorb heat, and reflect it towards the bottom of the pot. After installation, the energy-saving ring forms a through-ventilation section. One or more mounting holes are provided on the energy-saving ring.

[0004] In one or more embodiments, the energy-saving ring is provided with a first ring portion and a second ring portion, and a vertically penetrating vent portion is provided in the first ring portion or between the first ring portion and the second ring portion to ensure that the burner can be adequately supplied with oxygen, thereby ensuring combustion efficiency and enabling the gas to be completely burned.

[0005] By reflecting heat through the energy-saving ring, thermal efficiency is improved. At the same time, the energy-saving ring forms heat insulation, reducing the temperature rise of the burner head and the outer shell, and lowering the temperature inside the bottom shell, making the gas stove more energy-efficient, safe, and reliable during operation. In addition, the setting of the vent hole can effectively ensure that the oxygen supply to the first and second combustion sections is sufficient, so as to achieve complete combustion. The overall flat or concave design of the energy-saving ring prevents debris and soup from falling into the burner head, ensuring that the burner head remains clean for a long time.

[0006] In one or more embodiments, the diameter of the second ring is smaller than the diameter of the first ring, and the horizontal height of the first ring is lower than the horizontal height of the flame outlet of the second combustion section to ensure that the flame of the second combustion section is above the energy-saving ring during combustion, and also to ensure that the heat radiated downward by the second combustion section is reflected by the energy-saving ring.

[0007] In one or more embodiments, the second ring portion is located inside the first ring portion, and the horizontal height of the second ring portion is equal to the horizontal height of the first ring portion so that the energy-saving ring forms a plane, or the horizontal height of the second ring portion is lower than the horizontal height of the first ring portion so that the energy-saving ring forms a concave surface to ensure that the energy-saving ring can reflect heat, and the concave surface can also concentrate heat to form energy.

[0008] In one or more embodiments, the energy-saving ring is provided with one or more of an ignition needle mounting space or a flameout protection device mounting space, wherein the ignition needle mounting space or the flameout protection device mounting space is located within the ventilation section.

[0009] In one or more embodiments, a third ring may be provided, which may be integral with or separate from the energy-saving ring. The third ring may have a reflective ring surface, which may be concave or planar.

[0010] In one or more embodiments, the third ring is provided with a plurality of mounting holes through which the sub-burners of the multi-gun burner pass. The third ring is installed on the upper surface of the outer ring burner cap of the multi-gun burner. The third ring and the energy-saving ring are combined to form an energy-concentrating and cleaning ring to reflect heat and prevent debris and soup from entering the burner.

[0011] In one or more embodiments, the third ring may also be disposed on the three-ring stove head, the third ring is disposed between the outer ring fire cover and the middle fire cover, the energy-saving ring is disposed between the middle fire cover and the center fire cover, the third ring and the energy-saving ring are disposed separately, and the third ring is provided with a plurality of ventilation holes.

[0012] In one or more embodiments, the first combustion section forms a first flame cap, the first flame cap is provided with a conical slope, the conical slope and the energy-saving ring are combined to form an energy-concentrating concave surface and a cleaning concave surface, the conical slope is inclined downward towards the second combustion section, and the horizontal height of the lowest point of the conical slope is equal to or lower than the horizontal height of the outer edge of the energy-saving ring.

[0013] A stove, comprising the above-mentioned gas stove energy-saving ring structure.

[0014] The beneficial effects of this invention are as follows: By reflecting heat through the energy-saving ring, thermal efficiency is improved. Simultaneously, the energy-saving ring forms insulation, increasing thermal efficiency by 3-7 percentage points, meeting the new national standards. It reduces the temperature rise of the burner head and cooktop, as well as the temperature inside the bottom shell, making the gas stove more energy-efficient, safe, and reliable during operation. Furthermore, the vent design effectively ensures sufficient oxygen supply to both the first and second combustion sections, resulting in complete combustion. The overall planar or concave design of the energy-saving ring prevents debris and broth from falling into the burner head, ensuring its cleanliness over a long period. The most significant effect is that by adding an energy-saving ring to the burner without altering the existing stove structure, combustion efficiency can be significantly improved, effectively achieving 70% combustion efficiency in some existing stoves, meeting the requirements of the new national standards. This achieves a qualitative improvement in combustion efficiency at the lowest cost and also reduces smoke during combustion. Attached Figure Description
