Description

Technical Field

[0001] The utility model relates to the field of gas stoves, in particular to a fire cover and a gas stove. Background Art

[0002] The existing fire cover has an ignition hole, and together with the ignition needle, thermocouple and other components, it realizes the functions of generating flame and maintaining flame. The traditional inner ring fire cover has the risk of water from the bottom of the pot and long-term oil from the bottom of the pot entering the ignition hole and blocking the ignition hole. Therefore, the existing inner ring fire cover is generally integrally formed with a protective umbrella to protect the ignition needle. When oil, water droplets, etc. drip onto the top surface of the protective umbrella, they will still enter the ignition hole under the protective umbrella along the wall, and then block the ignition hole, resulting in poor ignition failure, and also affecting the stability of the flame and the uniformity of the flame distribution. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a fire cover and a gas stove in order to overcome the defect that the ignition hole is easily blocked in the prior art.

[0004] The utility model solves the above technical problems through the following technical solutions:

[0005] A fire cover comprises a fire cover body, the fire cover body comprises a plurality of main fire holes, and the plurality of main fire holes are arranged at intervals along the circumferential side wall of the fire cover body. The fire cover body also comprises a first groove, a second groove and a third groove, the first groove, the second groove and the third groove all cut the circumferential side wall of the fire cover body, and the first groove, the second groove and the third groove are arranged at intervals in sequence from top to bottom along the height direction of the fire cover body; the main fire holes comprise an upper main fire hole and a lower main fire hole, the upper main fire hole intersects with the first groove and the second groove respectively, and the lower main fire hole intersects with the second groove and the third groove respectively.

[0006] In this solution, multiple main fire holes are arranged at intervals as the flame outlets. The first groove, the second groove and the third groove are arranged in a circle around the fire cover body and are arranged in sequence. The grooves are connected to the main fire holes, which helps prevent the fire holes from being blocked and can stabilize the flame and provide a certain windproof function. The main fire holes and each groove are connected to each other by fluid. The first groove and the second groove cut the upper main fire hole into multiple sections, and the second groove and the third groove cut the lower main fire hole into three sections. When liquid such as soup overflows or food is boiled, the isolation between the grooves can effectively prevent the liquid from entering the main fire hole, reduce the accumulation of dirt inside the fire cover, and help maintain the stability of the flame; at the same time, a more uniform heat distribution is achieved, so that the food is heated more evenly and the cooking effect is better. The flame can flow freely between the grooves after being discharged from the main fire hole, which may help stabilize the flame and improve the combustion efficiency.

[0007] Preferably, in the height direction of the fire cover body, the first groove and the second groove are formed by the side wall of the fire cover body slanting downward and extending inward; the first groove and the second groove both intersect with the upper main fire hole and the two cut the upper main fire hole into three sections.

[0008] In this solution, the first groove and the second groove are both configured as oblique grooves, and their openings are both inclined upward structures, which help guide the flame to concentrate upward, enhance the focusing effect of the flame, and make the flame more stable. The first groove and the second groove cut the upper main fire hole into three sections, effectively achieving the anti-blocking effect of the upper main fire hole, and can also achieve segmented control of the flame. The oblique design of the groove will enhance the heat conduction effect, making the flame more concentrated and accelerating the heating of the ingredients, thereby improving cooking efficiency.

[0009] Preferably, the third groove is formed by horizontally extending inwardly from the side wall of the fire cover body; the third groove and the second groove both intersect with the lower main fire hole, and the two cut the lower main fire hole into three sections.

[0010] In the present scheme, the third groove is a horizontal groove, which occupies a smaller space in the height direction of the fire cover body. When the third groove is set, there is no need to increase the height of the fire cover body; an oblique groove and a horizontal groove cut the lower main fire hole into three sections, which can effectively improve the effect of preventing impurities such as soup and oil from entering the fire hole and the inside of the fire cover during use. At the same time, adding horizontal grooves can also enhance the heat conduction effect. Through the design of segmented flame control and concentrated flame, the fuel utilization efficiency is improved, thereby achieving the purpose of energy saving and environmental protection, making the flame more concentrated and accelerating the heating of ingredients, thereby improving cooking efficiency.

[0011] Preferably, the fire cover body also includes an ignition hole, which is arranged on the side wall of the fire cover body. The ignition hole includes a step ignition hole and two oblique ignition holes, and the two oblique ignition holes are respectively arranged on both sides of the step ignition hole; the oblique ignition hole is inclined upward from the inside of the fire cover body to the outside of the fire cover body, and the first groove is formed by the side wall of the fire cover body that is inclined downward and extends inward, and the first groove intersects with the oblique ignition hole.

[0012] In this solution, the oblique ignition holes provide additional ignition options on the traditional ignition method. The two oblique ignition holes are respectively arranged on both sides of the step ignition hole, providing a variety of ignition angles, making ignition more convenient and flexible. The oblique ignition holes are inclined from the inside to the outside of the fire cover body, which is conducive to the generation and diffusion of flames during ignition. The first groove intersects with the oblique ignition holes, which improves the ignition efficiency and success rate, making the ignition process simpler and faster.

[0013] Preferably, the fire cover body further comprises a plurality of lower flame stabilizing holes, which are arranged at intervals on the circumferential side wall of the fire cover body and located at the lower side wall of the fire cover body, and the plurality of lower flame stabilizing holes intersect with the third groove.

[0014] In this solution, the lower flame stabilizing hole helps to form a stable airflow at the bottom of the flame, thereby enhancing the stability of the flame and reducing the occurrence of flame breakage or instability. The lower flame stabilizing hole intersects with the third groove, which helps to form a more uniform airflow at the bottom of the flame, and the shape and stability of the flame can be further optimized through the design of the third groove.

[0015] Preferably, the fire cover also includes a top cover, which is connected to the fire cover body and is provided with an extension portion; the circumferential side wall of the fire cover body is provided with an ignition groove, the ignition groove is arranged in a semicircular shape, and the ignition groove is arranged below the extension portion.

[0016] In the present solution, the top cover is connected to the fire cover body to form a complete fire cover structure. The top cover is provided with an extension portion, which can extend outward by a certain area relative to the top cover, thereby effectively blocking overflowed soup and oil stains, etc., and reducing the entry of pollutants into the fire cover to block the fire holes, etc. The semicircular ignition groove can reduce the cutting range of the groove on the fire cover body, which is beneficial to maintaining the strength of the fire cover itself and the stability of the structure. The ignition groove is arranged below the extension portion, which helps to maintain the cleanliness of the ignition groove and avoid oil stains blocking the ignition groove, thereby providing a better use experience and safety, while enhancing the stability and functionality of the fire cover.

[0017] Preferably, the fire cover body also has an anti-blocking groove, which is arranged above the first groove along the height direction of the fire cover body, and is formed by horizontally extending the side wall of the fire cover body inward; the fire cover body also includes a plurality of upper flame stabilizing holes, which are arranged at intervals on the circumferential side wall of the fire cover body and intersect with the anti-blocking groove.

[0018] In this solution, the anti-blocking groove is arranged above the first groove, which can prevent food or other debris from blocking the first groove and keep the flame burning smoothly. The intersection of the upper flame-stabilizing hole and the anti-blocking groove can produce a stable flame, enhance the combustion efficiency of the flame, and further prevent food and other impurities from blocking the upper flame-stabilizing hole, so that the fire cover can continuously provide a stable airflow, making the flame more uniform and lasting.

[0019] Preferably, the anti-blocking groove is communicated with the ignition groove, and the anti-blocking groove and the ignition groove are flush in the circumferential direction of the fire cover.

[0020] In the present scheme, the width of the anti-blocking groove and the ignition groove is only such that the ignition groove falls into the anti-blocking groove, that is, on the side wall of the fire cover body, the anti-blocking groove and the ignition groove overlap, which can effectively reduce the space occupied by the two grooves being set separately. At the same time, the space between the anti-blocking groove and the ignition groove is interconnected, which helps to enhance the anti-blocking function of the anti-blocking groove. When the ignition groove is cleaned, the connectivity of the anti-blocking groove can prevent the ignition groove from being blocked by dirt, keep the ignition groove unobstructed, and improve the efficiency and success rate of ignition. During cleaning, dirt can be discharged smoothly through the connecting channel between the anti-blocking groove and the ignition groove, reducing the difficulty and time of cleaning.

[0021] Preferably, the fire cover further comprises a guide groove, and the guide groove is arranged opposite to the extension portion.

[0022] In this solution, the provision of the guide groove helps to guide liquids such as soup to move along a specific path, preventing them from flowing into the interior of the fire cover and accumulating and blocking the fire holes, thereby helping to maintain the cleanliness and tidiness of the fire cover.

[0023] A gas stove, comprising the fire cover as described in any one of the above items.

[0024] In the present solution, by cutting and setting each fire hole with two oblique grooves and a horizontal groove on the fire cover, it is possible to better prevent impurities such as oil, soup, etc. from entering the fire cover or accumulating in the fire holes during use. The size and direction of the flame can also be better controlled, so that heat can be more evenly transferred to the surface of the food, thereby improving cooking efficiency. It also helps to improve the safety of the gas stove, such as the anti-blocking groove, the ignition groove, etc., which can reduce the possibility of accidents and ensure the safety of users.
