Abstract
Description
Technical Field
[0001] This utility model relates to the field of kitchen gas equipment technology, and in particular to a flame baffle device for a gas stove. Background Technology
[0002] In traditional gas stoves, the flame typically heats the pot by directly contacting the burner head with the bottom of the pot. However, during actual cooking, the flame tends to spill outwards around the bottom of the pot, especially on low or medium heat. This can cause the pot handle, the outer edge of the pot, and even the stovetop to be subjected to prolonged high temperatures, potentially melting plastic parts and scorching wooden parts, posing a significant safety hazard. Furthermore, flame spillage reduces heating efficiency, leading to heat dispersion and low gas utilization.
[0003] Furthermore, most existing gas stoves lack effective flame guiding or baffle structures. Airflow disturbances in the kitchen environment (such as opening and closing doors, and the airflow from range hoods) can easily cause flame instability, leading to flame deviation and flameout. This not only affects cooking results but may also pose a risk of gas leaks. Therefore, there is an urgent need for a structurally sound and multifunctional flame baffle device to address issues such as flame overflow, cookware compatibility, and flame stability, thereby improving combustion efficiency and kitchen safety. Utility Model Content
[0004] To achieve the above objectives, this utility model provides a flame baffle device for a gas stove, comprising a cover body. The cover body includes an annular closed structure with openings at the top and bottom, and a support ring integrally formed on the upper edge of the annular closed structure. The inner diameter of the upper edge of the annular closed structure is larger than the inner diameter of the lower edge to ensure that the cover body can be stably installed outside the gas stove burner ring. The support ring is used to support the pot body. The lower side wall of the cover body is provided with a plurality of vent holes evenly distributed circumferentially to supplement the combustion air required for the flame root. The upper side wall of the cover body is provided with two air passages. The extension direction of the air passages is consistent with the radial direction of the cover body. The two air passages are offset circumferentially on the cover body to guide the flow of hot air.
[0005] Furthermore, the longitudinal profile of the annular closed structure is composed of an upper outward-expanding arc segment and a lower inward-contracting arc segment, so that the cover gradually expands outward from the inner edge to the outer edge and gradually converges from the upper edge to the lower edge, forming a streamlined profile, which helps guide airflow and stabilize the structure.
[0006] Furthermore, in one embodiment of this utility model, the device further includes a cover, which is disposed at the central opening of the support ring. The cover is a circular plate concentric with the support ring. The inner edge of the support ring is provided with a limiting flange. The outer diameter of the cover matches the inner diameter of the inner edge of the support ring, so that the edge of the cover can be stably placed on the limiting flange of the inner edge of the support ring. It can be adapted to a frying pan and heats the frying pan by conducting heat through the cover.
[0007] Furthermore, in another embodiment of this utility model, a plurality of concentric circular furnace rings are arranged between the support ring and the cover. Each furnace ring has a limiting flange on its inner and outer edges. The limiting flanges of adjacent furnace rings match and overlap to fix each other, forming an annular opening between adjacent furnace rings to accommodate pots of different sizes.
[0008] Furthermore, the width of the concentric rings is preferably 20mm.
[0009] Furthermore, the inner diameter of the vent is 6-10 mm to balance airflow and structural strength.
[0010] Furthermore, the cross-section of the airway is rectangular, which helps guide the airflow and ensures uniform flow distribution.
[0011] Furthermore, the cover is made of galvanized steel sheet to improve its high temperature resistance and corrosion resistance, while also enhancing structural strength and ensuring long-term reliability.
[0012] Furthermore, the enclosure, cover, and concentric furnace ring are all made of galvanized steel sheet to improve the overall structure's high temperature resistance, corrosion resistance, and long-term reliability.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] This utility model, through the design of an annular closed cover and circumferentially distributed ventilation holes, can effectively block the flame, prevent the flame from overflowing and baking the pot handle, and ensure sufficient air circulation required for combustion, thus preventing incomplete combustion.
[0015] The air ducts, which are offset at the top of the enclosure, are used to guide the hot air generated inside the enclosure to one side. At the same time, because the air ducts are positioned high, the hot air is discharged instead of flames, reducing the risk of burns and improving the kitchen environment.
[0016] When used with the lid, it can be used with frying pans, and the lid conducts heat to heat the frying pan, meeting diverse cooking needs.
[0017] In addition, this utility model improves the adaptability and ease of use of the device by setting multiple concentric furnace rings between the support ring and the cover, allowing users to select the corresponding opening according to the size of the pot. Attached Figure Description

[0026] The following will describe the technology of the embodiments of the present utility model clearly and completely with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present utility model. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present utility model can be combined with each other.
[0027] Example 1:
[0028] like Figures 1 to 4As shown, this embodiment proposes a flame baffle device for a gas stove, including a cover 1. The cover 1 includes an annular closed structure 101 with openings at the top and bottom, and a support ring 102 integrally formed on the upper edge of the annular closed structure 101. The inner diameter of the upper edge of the annular closed structure 101 is larger than the inner diameter of the lower edge, and the inner diameter of the lower edge is larger than the outer diameter of the burner ring of the gas stove, to ensure that the cover 1 can be securely fitted onto the outside of the burner ring of the gas stove from above. The support ring 102 is used to support the pot body.
[0029] The lower sidewall of the enclosure 1 is provided with a plurality of vent holes 103 evenly distributed circumferentially to supplement the air required at the base of the flame and ensure complete combustion. Preferably, the inner diameter of the vent holes 103 is 6-10 mm to balance air circulation and the structural strength of the enclosure 1.
[0030] Two air ducts 104 are provided on the upper side wall of the cover 1. The extension direction of the air ducts 104 is consistent with the radial direction of the cover 1, and the two air ducts 104 are offset around the circumference of the cover to guide the hot airflow to one side and effectively prevent the flame from escaping or being disturbed by external airflow. Preferably, the cross-section of the air duct 104 is rectangular to facilitate the directional guidance of airflow.
[0031] like Figure 2 As shown, the longitudinal profile of the annular closed structure 101 is composed of an upper outward-expanding arc-shaped section and a lower inward-converging arc-shaped section that smoothly transitions to the upper part. It gradually expands outward from the inner edge to the outer edge and gradually converges from the upper edge to the lower edge, forming a streamlined structure, which not only helps guide airflow but also enhances the overall stability of the cover.
[0032] like Figure 4 As shown, this embodiment also includes a cover 2, which is disposed at the central opening of the support ring 102 and is a circular plate concentric with the support ring. The inner edge of the support ring 102 is provided with a limiting flange 105. The outer diameter of the cover 2 matches the inner diameter of the inner edge of the support ring, allowing the edge of the cover 2 to be securely placed on the limiting flange 105. After the pot body is removed, the cover 2 can be placed in the central opening, adaptable to a flat-bottomed pot, and heat is conducted through the cover to heat the pot.
[0033] Preferably, both the cover 1 and the cover 2 are made of galvanized steel sheet with a thickness of 0.6 to 1.2 mm, which has good heat resistance and corrosion resistance and is suitable for use in kitchen gas stove environments.
[0034] The working principle of this embodiment:
[0035] In this embodiment, the cover 1 is fitted over the outside of the burner ring of the gas stove, with the inner diameter of the lower edge of the cover 1 being larger than the outer diameter of the burner ring, ensuring that the cover 1 can be securely fitted around the gas stove. The pot is placed at the center opening of the support ring 102, forming an annular channel between the bottom of the pot and the support ring 102, facilitating the rise of flames and airflow from the annular channel to heat the bottom of the pot.
[0036] The cover 1 effectively blocks the flame during use, preventing it from escaping or spreading along the outer edge of the pot, thus avoiding heating the pot handle or gas stove panel and improving kitchen safety. The lower side wall of the cover 1 has ventilation holes 103 to replenish the air needed for combustion, ensuring complete and stable combustion.
[0037] During use, users can orient the two air ducts 104 of the cover 1 outwards according to actual needs, allowing the hot air generated inside the cover to be discharged along the air ducts 104, thus preventing heat accumulation. Since the air ducts 104 are located at the top of the cover 1, no flames will be directly emitted; only hot air will be discharged, further reducing the risk of burns to the kitchen environment and cookware handles.
[0038] When using a frying pan, the pan can be placed directly on the cover 2, and the heat will be conducted through the cover to heat the pan.
[0039] Example 2:
[0040] like Figures 5 to 7 As shown, this embodiment is a further improvement on embodiment 1. Multiple concentric rings 3 are arranged sequentially between the support ring 102 and the cover 2. Each ring 3 has a limiting flange 105 on its inner and outer edges. The limiting flanges 105 between adjacent rings match and overlap to form a stable stacked structure, and an annular opening is formed between adjacent rings. The pot body can be placed in a suitable ring according to its size, enhancing adaptability.
[0041] The outermost ring has an outer diameter that matches the inner diameter of the support ring 102, and the innermost ring has an inner diameter that matches the outer diameter of the cover 2. When the pot is removed, the cover 2 can also be placed on the innermost ring.
[0042] The concentric ring 3 is also made of galvanized steel plate, with high structural strength, excellent high temperature resistance, and can be used for a long time.
[0043] Preferably, the concentric rings 3 are all the same size, with a width of 20mm.
[0044] The working principle of this embodiment:
[0045] In this embodiment, the cover 1 is fitted over the outside of the gas stove's burner ring, ensuring that the inner diameter of the lower edge of the cover 1 is larger than the outer diameter of the burner ring, thus guaranteeing a stable installation of the cover 1. The pot body can be placed on the concentric ring 3 between the support ring 102 and the cover 2 according to its actual size. Pot bodies of different sizes can be placed on different levels of ring 3, thereby adjusting the size of the central opening to meet the needs of various pot sizes.
[0046] During use, the flame is effectively blocked by the cover 1, preventing it from escaping along the outer edge of the pot and avoiding the high-temperature flame from baking the pot handle or stove panel, thus improving safety. The lower side wall of the cover 1 is provided with a vent 103 to ensure the air supply required for flame combustion and prevent incomplete combustion.
[0047] Similarly, during use, users can orient the two air ducts 104 of the enclosure 1 towards the outside of the kitchen, allowing the hot air generated inside the enclosure to be discharged through the air ducts 104, preventing high temperatures from accumulating around the pot and reducing the impact on operators and the kitchen environment. Since the air ducts 104 are located at the top of the enclosure, the discharged air is hot air rather than flames, ensuring safety during kitchen use.
[0048] When using a frying pan, the pan can be placed directly on the cover 2, and the heat will be conducted through the cover to heat the pan.
