Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a copper core, a burner and a gas cooker. Background Art

[0002] Gas stoves generate heat by igniting combustible gases such as natural gas, and then use this heat for cooking. A gas stove primarily consists of a burner, which consists of a flame cap and an ignition device. Combustible gas is ejected from the flame holes in the flame cap, and the ignition device ignites the combustible gas, generating heat.

[0003] During the cooking process, the pot may overflow, and soup, rice residue and other objects may block the flame stabilizing holes and / or ignition holes of the copper core of the fire cover, causing accidental flameout and poor ignition.

[0004] To address issues like unexpected flameout and poor ignition, the existing method involves removing the copper core, cleaning it, and removing any obstructions in the flame-stabilizing and / or ignition holes, allowing normal combustion. This method has drawbacks, including the difficulty for users in identifying whether unexpected flameout and poor ignition are caused by blockage in the flame-stabilizing and / or ignition holes. This is particularly true when the copper core is integrally locked or cannot be removed due to prolonged use. This makes it impossible to check whether the flame-stabilizing and / or ignition holes are blocked, and even more difficult to clean, resulting in a poor user experience. Utility Model Content

[0035] This embodiment discloses a copper core, a burner and a gas cooker including the burner, which can generate heat for cooking by burning combustible gas. Figures 1 to 3 As shown, the burner includes a copper core 1, a thermocouple 2, an electrode needle 3, a nozzle seat and a burner head. The thermocouple 2 and the electrode needle 3 are respectively installed on the nozzle seat; a copper core threaded hole is opened on the copper core 1, and a burner head through hole is opened on the burner head. The screw passes through the burner head through hole and enters the copper core threaded hole, thereby locking the burner head and the copper core 1 together; then the burner head is placed on the nozzle seat to complete the installation of the burner.

[0036] like Figures 1 to 6 As shown, a first flame stabilizing hole 11, a second flame stabilizing hole 12, a main fire hole 13 and an ignition hole 14 are provided on the bottle cap-shaped copper core. The first flame stabilizing hole 11, the second flame stabilizing hole 12 and the ignition hole 14 are respectively located below the main fire hole 13. The ignition hole 14 extends toward the direction of the electrode needle 3, and the ignition success rate is high.

[0037] The axis of the second flame-stabilizing hole 12 intersects with the axis of the first flame-stabilizing hole 11 on the outside of the copper core 1 or their projections on the horizontal plane, that is, at least two flame-stabilizing holes are provided on the copper core 1, and the extension directions of the two flame-stabilizing holes are inconsistent. When one flame-stabilizing hole is blocked by soup or food debris overflowing from the pot, the other flame-stabilizing holes still have a certain probability of being unobstructed. The axis of the second flame-stabilizing hole 12 and the axis of the first flame-stabilizing hole 11 are both aligned with the thermocouple 2. As long as there is one flame-stabilizing hole in an unobstructed state, the fire can be maintained and the stability of the fire maintenance can be improved. The flame combustion can burn away the soup, food debris and other objects that are blocked in the flame-stabilizing hole, thereby restoring the flame-stabilizing hole to an unobstructed state, solving the problem that the burner fire hole is easily blocked, difficult to clean, and difficult to unclog.

[0038] On the basis of the above structure, at least two first flame-stabilizing holes 11 and at least two second flame-stabilizing holes 12 are sequentially arranged along the circumference of the copper core 1. Taking the intersection of the first flame-stabilizing hole 11 and the second flame-stabilizing hole 12 as the origin, the first flame-stabilizing holes 11 are counted in sequence in the direction of the first flame-stabilizing hole 11, and the second flame-stabilizing holes 12 are counted in sequence in the direction of the second flame-stabilizing hole 12.

[0039] The axes of the nth first flame-stabilizing hole 11 and the nth second flame-stabilizing hole 12 intersect outside the copper core 1 or their projections on a horizontal plane intersect, where n is a positive integer (1, 2, 3, ...). The smaller the value of n, the closer the intersection point On of the axes of the first and second flame-stabilizing holes 11, 12 is to the copper core 1. That is, the intersection point O1 of the axes of adjacent first and second flame-stabilizing holes 11, 12 is closest to the copper core 1, and the intersection point O2 of the axes of the next-next-adjacent first and second flame-stabilizing holes 11, 12 is farther away from the copper core 1 than O1.

[0040] Thermocouple 2 is located within the intersection of the axes of all flame-stabilizing holes. In this embodiment, the axis of thermocouple 2 is located between O1 and O2. Because thermocouple 2 is a cylindrical object with a set radius, both O1 and O2 are actually located within the range of thermocouple 2. In other words, the combustible gas ejected from the adjacent first and second flame-stabilizing holes 11, 12 contacts the outer wall of thermocouple 2 before reaching the intersection of the axes O1.

[0041] In the burner, the combustible gas can smoothly reach the thermocouple 2 after being ejected from any flame stabilizing hole, and will not change direction due to premature collision with the combustible gas ejected from other flame stabilizing holes, so the flame-keeping ability is stronger.

[0042] To facilitate unclogging the flame-stabilizing holes, in this embodiment, the axes of the first and second flame-stabilizing holes 11, 12 are tilted upward relative to the horizontal plane, extending radially outward from the copper core 1. That is, from the outer wall of the copper core 1 facing the interior of the copper core 1, the axes of the first and second flame-stabilizing holes 11, 12 are tilted downward. When a user unclogs the flame-stabilizing holes from the outside using a cleaning device such as a bamboo stick, objects clogged in the holes can fall through the holes into the inner cavity of the burner, where they will carbonize and decompose after prolonged use. Similarly, the ignition hole 14 can also be shaped with a higher outer end and a lower inner end to facilitate unclogging.

[0043] The inclination angles of the first and second flame-stabilizing holes 11, 12 are not limited. In this embodiment, 0° < inclination angle α2 ≤ 60°. This allows combustible gas to be ejected more smoothly from the flame-stabilizing holes and reach the thermocouple 2, ensuring flame stability. The outer ends of the flame-stabilizing holes are higher than the inner ends. If the pot overflows during cooking, liquid, rice residue, and other materials entering the flame-stabilizing holes will flow downward, reducing the likelihood of blockage and preventing accidental flameout and ignition problems.

[0044] In addition to the above structure, a flame-keeping groove 15 is further formed on the outer wall of the copper core 1. This groove is located below the first flame-stabilizing hole 11, the second flame-stabilizing hole 12, and the ignition hole 14, and is aligned with the thermocouple 2 and the electrode needle 3, respectively. This groove improves the success rate of ignition and flame-keeping, providing a better user experience. The combustible gas in the groove burns away any spilled material, such as soup and rice residue, located in the flame-stabilizing and ignition holes 14, reducing the likelihood of blockage and facilitating burner cleaning.

[0045] The specific shape of the flame-preserving groove 15 is not limited. In this embodiment, the flame-preserving groove 15 is a long, narrow strip-shaped groove. Its outer portion does not intersect with the flame-stabilizing hole or the ignition hole 14. Its end located inside the copper core 1 intersects with the first flame-stabilizing hole 11, the second flame-stabilizing hole 12, and the ignition hole 14. Even when the flame-stabilizing hole and the ignition hole 14 are blocked, the flame-preserving groove 15 can still burn stably, ensuring that the flame does not go out and ignition is normal.

[0046] In order to achieve that the end of the fire-keeping groove 15 located on the inner side of the copper core 1 intersects with the first flame-stabilizing hole 11, the second flame-stabilizing hole 12 and the ignition hole 14 respectively, in this embodiment, the extension direction of the fire-keeping groove 15 is tilted downward along the radial outward direction of the copper core 1, and the tilt angle α1 is 0°≤30°, which is convenient for processing; the fire-keeping groove 15 is tilted downward, and the overflowing soup, rice residue and other objects cannot flow into the fire-keeping groove 15, thereby avoiding the fire-keeping groove 15 from being blocked, thereby solving the problem of the existing copper core 1 being extinguished and unable to ignite due to overflow.

[0047] Based on the above structure, a boss 16 is formed on the outer wall of the copper core 1. The main flame hole 13 is located above the boss 16, and the first flame stabilization hole 11, the second flame stabilization hole 12, and the ignition hole 14 are located below the boss 16. The main flame hole 13 is a stepped hole, which makes the air outlet more stable; the boss 16 can prevent some of the overflowing soup, rice residue, etc. from flowing into the flame stabilization hole and ignition hole 14, reducing the probability of blockage of the flame stabilization hole and the ignition hole 14, and improving the user experience.

[0048] Note that the above are only preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
