Description

Technical Field

[0001] This utility model relates to the technical field of oil-fired stoves and gas-fired stoves, and in particular to a composite diffused flame stove head cover for a cooker. Background Technology

[0002] A compression combustion furnace is a type of tubular furnace. It uses a fan or compressor to blow air into the combustion chamber, ignites the fuel with an igniter, and rapidly propels the flame out under the force of the air.

[0003] In existing stoves, the flame from the burner core typically shoots out in a concentrated burst from the burner head. However, the flame's distribution is limited by the burner head's diameter, resulting in uneven heat distribution. Furthermore, existing burner heads lack effective flame guiding, leading to poor flame distribution and a small flame area on the bottom of the pot, causing the cookware to be heated in a concentrated manner. This concentrated heating area, limited by the burner head's diameter, makes the cookware prone to scorching and other problems during cooking.

[0004] In view of this, the inventor of this case conducted in-depth research, which led to the creation of this case. Utility Model Content

[0005] The purpose of this invention is to provide a composite flame-dispersing stove head cover that can better distribute and diffuse the flame, making the flame more uniform and increasing the heating area of ​​the cookware.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A composite diffused flame stove cover for a cooker includes a top cover and a bottom cover arranged alternately on top and bottom, with a flame-guiding interlayer between them. The bottom cover is positioned and supported on the upper part of the stove head. The flame-guiding interlayer and the top cover protrude from the upper edge of the stove head. The bottom cover and the top cover are coaxially arranged with the stove head. The bottom cover and the top cover are fixedly connected together by a shaft connector.

[0008] The bottom cover has a plurality of first ignition grooves arranged along its circumference, and the top cover has a plurality of second ignition grooves arranged along its circumference. The first ignition grooves are opened along the radial direction of the bottom cover, and the second ignition grooves are opened along the radial direction of the top cover. The second ignition grooves are corresponding to or staggered with the first ignition grooves. The width of the opening of the first ignition groove is correspondingly larger than that of the second ignition groove. The area of ​​the ignition grooves of the bottom cover is larger than that of the ignition grooves of the top cover.

[0009] The bottom perimeter of the top cover is provided with a beveled cut or a rounded opening.

[0010] Furthermore, taking the location of the shaft connector as the inside and the direction away from the shaft connector as the outside, the first fire guide groove is strip-shaped, and its groove width gradually increases uniformly from the inside to the outside. The second fire guide groove is also strip-shaped, and its groove width gradually increases uniformly from the inside to the outside.

[0011] Furthermore, the top cover is also provided with a number of third ignition channels arranged along its own circumferential direction. The third ignition channels are arranged corresponding to or intersecting with the second ignition channels. The third ignition channels are strip-shaped, and their opening width gradually increases uniformly from the inside to the outside. The ignition channel area of ​​the bottom cover includes the opening area of ​​the first ignition channel and the opening area of ​​the third ignition channel.

[0012] Furthermore, the second ignition groove is provided in a one-to-one correspondence with the first ignition groove, and the third ignition groove is provided in an alternating manner with the second ignition groove. Each of the third ignition grooves is located at the middle position between two adjacent second ignition grooves. The first ignition grooves are evenly distributed, the second ignition grooves are evenly distributed, and the third ignition grooves are evenly distributed.

[0013] Furthermore, the length of the second ignition groove is greater than that of the third ignition groove.

[0014] Furthermore, the inner end of the second fire guide groove extends to the periphery of the center position of the top cover, and the outer end of the second fire guide groove extends to the position of the top cover near its own periphery.

[0015] Furthermore, an oil guiding portion is formed at the center of the bottom cover, and an oil guiding groove is formed by recessing the bottom surface of the oil guiding portion upward. The bottom surface of the oil guiding groove is a concave arc surface, and one end of the first fire guiding groove extends to the outside of the oil guiding portion.

[0016] Furthermore, the shaft connector is a fastening bolt, a welded connector, or a cast connector.

[0017] After adopting the above technical solution, the composite flame-dispersing stove cover of this utility model has the following beneficial effects: the flames that shoot straight up vertically are diffused horizontally to expand the heat area by using the fire-guiding layer. Furthermore, the design of the oblique cut or rounded opening is used to adjust the flames in the horizontal direction to be tilted upwards again. In this way, the stove cover adopts a double-layer structure. After the flames pass through the first fire-guiding groove, part of them shoots upward through the second guide groove, and another part is guided by the fire-guiding layer to diffuse in all directions and then shoots upwards to the periphery of the top cover. This can improve the heat utilization efficiency of the cookware. The flames distributed by the double-layer stove cover of this utility model are more uniform and more dispersed, which can greatly increase the heating area of ​​the cookware.

[0018] Furthermore, the fuel ejected with the flame can be collected through the oil guide groove and diffused circumferentially using the concave arc surface, which facilitates re-combustion, improves fuel utilization, and promotes more complete combustion of fuel. This avoids incomplete combustion and fuel waste caused by fuel dripping directly due to gravity. Attached Figure Description

[0025] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0026] This utility model relates to a composite diffuser stove head cover for a cooker, consisting of... Figures 1-4 As shown, the device includes a top cover 1 and a bottom cover 2 arranged alternately, forming a flaming interlayer 3 between them. The bottom cover 2 is positioned to support the upper part of the burner head (not shown in the figure). The flaming interlayer 3 and the top cover 1 protrude from the upper edge of the burner head. The burner head has cylindrical sidewalls, and the bottom cover 2 and the top cover 1 are both disc-shaped. The bottom cover 2 and the top cover 1 are coaxially arranged with the burner head and are fixedly connected together by a shaft connector 4. The shaft connector 4 can be a fastening bolt, a welded connector, or a cast connector. The bottom cover 2 and the top cover 1 can be fastened together by bolts, welding, or casting.

[0027] The bottom cover 2 has several first ignition grooves 21 arranged along its own circumferential direction, and the top cover 1 has several second ignition grooves 11 arranged along its own circumferential direction. The first ignition grooves 21 are opened along the radial direction of the bottom cover 1, and the second ignition grooves 11 are opened along the radial direction of the top cover 1. In this embodiment, the second ignition grooves 11 and the first ignition grooves 21 are arranged in a one-to-one correspondence. The width of the groove opening of the first ignition groove 21 is correspondingly larger than that of the second ignition groove 11, and the area of ​​the ignition grooves 21 of the bottom cover 2 is larger than the area of ​​the ignition grooves of the top cover 1.

[0028] The bottom periphery of the top cover 1 is provided with a beveled or rounded opening, allowing the flames that spread outwards to shoot upwards, facilitating contact with the cookware for heating. In this embodiment, the bottom periphery of the top cover 1 is provided with a beveled opening 5. In this utility model, in addition to using a beveled opening or a rounded opening, other notched structures can also be used to facilitate the upward shooting of the flames; all can be considered equivalent replacements for the beveled opening or the rounded opening.

[0029] In a preferred embodiment, with the location of the shaft connector 4 as the inside and the direction away from the shaft connector 4 as the outside, the first ignition channel 21 is strip-shaped, and its width gradually increases uniformly from the inside to the outside, which facilitates guiding some of the flames to spread in all directions and can ensure the uniformity of the distribution of the flames rushing out in the area of ​​the top cover 1. The second ignition channel 11 is strip-shaped, and its width gradually increases uniformly from the inside to the outside. The shape of the second ignition channel 11 is consistent with that of the first ignition channel 21, and the position of the second ignition channel 11 corresponds to that of the first ignition channel 21, which facilitates the second ignition channel 11 to fully guide the flames rushing out from the first ignition channel 21.

[0030] Furthermore, the top cover 1 is also provided with several third ignition channels 12 arranged along its own circumference. The third ignition channels 12 are staggered with the second ignition channels 11. The third ignition channels 21 are strip-shaped, and their width gradually increases uniformly from the inside to the outside. This makes the flames that rush out in the area where the top cover 1 is located more evenly distributed.

[0031] Furthermore, the length of the second ignition groove 11 is greater than that of the third ignition groove 12.

[0032] Furthermore, the inner end of the second ignition groove 11 extends to the periphery of the center position of the top cover 1, and the outer end of the second ignition groove 11 extends to the position of the top cover 1 near its own periphery.

[0033] In this invention, the distance between the top cover 1 and the bottom cover 2 (i.e., the interlayer width of the ignition jacket 3) can be adjusted according to the size of the burner head and other factors, so as to achieve uniform dispersion of flames in the area where the burner head cover is located and around the burner head cover.

[0034] This invention utilizes the fire-guiding layer 3 to diffuse the vertically rising flames to the horizontal direction. Furthermore, by employing a beveled or rounded design, the horizontal flames are adjusted to be tilted upwards again. Thus, the burner cover adopts a double-layer structure. After the flames pass through the first fire-guiding groove 21, part of them rushes upwards through the second guide groove 11, while another part is guided by the fire-guiding layer 3 to diffuse in all directions and then rushes upwards towards the periphery of the top cover 1. The flames, distributed twice by the double-layer burner cover, are more uniform and more dispersed, which can increase the heating area of ​​the cookware and improve the heat utilization efficiency.

[0035] As a preferred embodiment, such as Figure 4 As shown, an oil guiding part 6 is formed at the center of the bottom cover 2. An oil guiding groove 61 is formed by recessing the bottom surface of the oil guiding part 6 upwards. The bottom surface of the oil guiding groove 61 is a concave arc surface. One end of the first ignition groove 21 extends to the outside of the oil guiding part 61. In use, the fuel that rushes out with the flame can be collected through the oil guiding groove 61 and diffused circumferentially using the concave arc surface, which facilitates re-combustion, improves fuel utilization, and facilitates more complete combustion of fuel. This avoids incomplete combustion and fuel waste caused by fuel dripping directly due to gravity.

[0036] The above embodiments and accompanying drawings are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
