Abstract
Description
Technical Field
[0001] This invention relates to the field of pot rack technology, and more specifically, to a single-layer pot rack and stove. Background Technology The structure of the pot holder on a household gas stove significantly impacts combustion efficiency. Currently, pot holders are generally classified into three types: simple pot holders, single-layer pot holders, and disc-shaped pot holders. Disc-shaped pot holders offer the most significant improvement in thermal efficiency, but due to their large surface area, they are prone to getting dirty and are difficult to clean during cooking. Simple pot holders are easy to maintain due to their simple structure, but their heat retention is poor, resulting in the lowest thermal efficiency compared to the other two types. Meanwhile, existing single-layer pot holders have relatively low combustion efficiency. Summary of the Invention
[0002] The present invention aims to provide, for example, a single-layer pot rack and stove that provides burner combustion efficiency and is easy to clean.
[0003] The embodiments of the present invention can be implemented as follows: In a first aspect, the present invention provides a single-layer pot rack, comprising: Support ring and flange; The flange is located at the top of the support ring; The flange extends toward the center of the support ring, or the flange extends away from the center of the support ring.
[0004] In an optional embodiment, a support piece is also included, which is disposed on top of the support ring.
[0005] In an optional embodiment, a support leg is further included, which is disposed at the bottom of the support ring, and there is a gap between the bottom surface of the support leg and the bottom surface of the support ring.
[0006] In an optional embodiment, the flange extends away from the center of the support ring, and the horizontal distance between the inner wall of the support ring and the outer wall of the flange is A; The flange extends close to the center of the support ring, and the horizontal distance between the outer wall of the support ring and the inner wall of the flange is A, where A is 8-14 mm.
[0007] In an optional embodiment, the bottom of the support ring may also be provided with a folded edge, which extends in a direction toward the center of the support ring, or the folded edge extends in a direction away from the center of the support ring.
[0008] In an optional embodiment, the annular surface of the flange and the top surface of the support ring have a clamp α, -30°<α<30°.
[0009] In an optional embodiment, the flange is integrally formed with the support ring.
[0010] In an optional embodiment, the flange is an annular plate, which is arranged circumferentially along the top of the support ring to form a closed annular structure.
[0011] In an optional embodiment, the flange has the same thickness as the support ring.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0018] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.
[0019] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.
[0020] In the description of this invention, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed, they are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.
[0021] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.
[0022] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.
[0023] Please refer to Figure 1 This embodiment provides a single-layer pot rack, comprising: Support ring 100 and flange 200; The flange 200 is set at the top of the support ring 100; The flange 200 extends in a direction toward the center of the support ring 100, or the flange 200 extends in a direction away from the center of the support ring 100.
[0024] The support ring 100 of this single-layer pot rack can be fitted onto the outside of the burner 22, and the inner wall of the support ring 100 can enclose a heat-gathering zone 11. The heat-gathering zone 11 can concentrate heat and prevent the heat generated by the burner 22 from dissipating; it can also provide a continuous high-temperature environment for the burner 22, ensuring complete combustion of gas and air. This saves gas consumption while maintaining the thermal efficiency of the burner 22. Furthermore, compared to a disc-shaped pot rack with a large expansion area that is prone to getting dirty and difficult to clean during cooking, the support ring 100 has a small expansion area, preventing stains from splashing and sticking, thus improving the ease of cleaning. The flange 200 is located at the top of the support ring 100, ensuring that the discharged heat adheres to the bottom of the pot to improve thermal efficiency, and also increasing the structural strength of the support ring 100. In summary, this single-layer pot rack has the advantages of simple structure, convenient arrangement, high thermal efficiency, and easy cleaning.
[0025] Please continue reading. Figure 1 , Figure 2 and Figure 3 As can be seen from the figure, the flange 200 extends in a direction away from the center of the support ring 100. It is easy to understand that in other embodiments of the present invention, the flange 200 may also extend in a direction toward the center of the support ring 100, as long as the flange 200 is located on the support ring 100. This is just an example and is not intended to limit the scope.
[0026] In this embodiment, both the support ring 100 and the flange 200 are annular, and the inner wall of the flange 200 is flush with the inner sidewall of the support ring 100. Furthermore, the support ring 100 is a cylindrical annular structure, and the flange 200 is located on an annular flat plate. This ensures the flatness of the inner sidewalls of the support ring 100 and the flange 200.
[0027] The support ring 100 has four elongated air inlets 110 evenly distributed circumferentially. Along the axis of the support ring 100, the top of the air inlet 110 is 5-10 mm above the vertical height of the burner orifice 22a to prevent heat from escaping through the air inlet 110. The multiple air inlets 110 are evenly distributed on the support ring 100, corresponding to the lower end of the burner 22's main burner orifice 22a, facilitating sufficient secondary air replenishment.
[0028] As can also be seen from the figure, in an optional embodiment, an inwardly flanged structure 111 is formed at the periphery of the air inlet 110 facing the center of the support ring 100, and the inwardly flanged structure 111 is arranged end to end along the periphery of the air inlet 110. The inwardly flanged structure 111 of the air inlet 110 can improve the overall strength of the support ring 100 and has a certain guiding effect on the airflow of the air inlet 110. It is easy to understand that in other embodiments, the inwardly flanged structure 111 may not be provided, and only the air inlet 110 may be provided.
[0029] In an optional embodiment, the thickness of the inner flange structure 111 is 2-3 mm in the direction from the inner sidewall of the support ring 100 to the center of the support ring 100.
[0030] In an optional embodiment, a support piece 310 is also included, which is disposed on the top of the support ring 100. The support piece 310 is used to support the cookware 21. It is easy to understand that the support piece 310 can also be disposed on the flange 200 and / or the support ring 100; this is merely an example and is not intended to be limiting.
[0031] In an optional embodiment, a support leg 320 is also included. The support leg 320 is disposed at the bottom of the support ring 100, and there is a gap between the bottom surface of the support leg 320 and the bottom surface of the support ring 100. The support leg 320 enables a gap to be formed at the bottom of the support ring 100, thereby facilitating the formation of a gas supply channel at the bottom of the support ring 100 and preventing heat from the support ring 100 from being directly conducted to the stove.
[0032] Optionally, a foot pad 330 is provided at the bottom of the support leg 320. The support leg 320 is placed on the water tray 23 via the foot pad 330.
[0033] In an optional embodiment, the flange 200 extends away from the center of the support ring 100, and the horizontal distance between the inner wall of the support ring 100 and the outer wall of the flange 200 is A; the flange 200 extends closer to the center of the support ring 100, and the horizontal distance between the outer wall of the support ring 100 and the inner wall of the flange 200 is A, where A is 8-14 mm. This dimensional setting allows for a better smoke vent 25 at the top of the flange 200, while also preventing heat dissipation caused by an excessively long flange 200.
[0034] In an optional embodiment, the bottom of the support ring 100 may also be provided with a folded edge, which extends in a direction toward the center of the support ring 100 or in a direction away from the center of the support ring 100. The folded edge can ensure the overall structural stability and reliability of the support ring 100.
[0035] In an optional embodiment, the annular surface of the flange 200 and the top surface of the support ring 100 have a clamp α, where -30° < α < 30°. In this embodiment, the annular surface of the flange 200 is parallel to the top surface of the support ring 100. Furthermore, the annular surface of the flange 200 is perpendicular to the axis of the support ring 100. It is easy to understand that in other embodiments of the present invention, flanges 200 with various angles can be provided to meet different usage requirements.
[0036] In an optional embodiment, the flange 200 and the support ring 100 are integrally formed. This increases the overall integrity of the pot frame and also ensures structural strength and stability.
[0037] In an optional embodiment, the flange 200 is an annular plate, and the flange 200 is arranged circumferentially along the top of the support ring 100 to form a closed annular structure. It is easy to understand that in other embodiments of the present invention, the flange 200 may also be a plurality of plates arranged at intervals; this is merely an example and is not intended to limit the scope.
[0038] In an optional embodiment, the flange 200 has the same thickness as the support ring 100, thereby ensuring the stability of the thermal conductivity of the single-layer pot rack.
[0039] like Figure 4 As shown, in a second aspect, the present invention provides a cooktop, which includes a single-layer pot rack according to any of the foregoing embodiments.
[0040] The flange 200 at the upper end of the support ring 100, together with the foot piece 300, forms a certain height for exhaust gas discharge, while also facilitating the slow flow of heat along the bottom of the pot, which helps improve thermal efficiency. The air inlet 110 at the lower end of the support ring 100 is used to supplement the air required for combustion. This air inlet 110 is lower than the burner 22 flame hole by a certain height to prevent the heat generated by combustion from flowing out from here. The air inlet 110 extends into the support ring 100 to form an inner flange structure 111, which helps to improve the overall strength of the support ring 100 and avoids the risk of overall deformation due to heat or force. In summary, the embodiments of the present invention provide a single-layer pot rack, which has at least the following advantages: The support ring 100 can be fitted onto the outside of the burner 22, and the inner wall of the support ring 100 can enclose and form a heat-gathering zone 11. The heat-gathering zone 11 can concentrate heat and prevent the heat generated by the burner 22 from dissipating; on the other hand, it can provide a continuous high-temperature environment for the burner 22 to operate, thereby ensuring complete combustion of gas and air. This ensures the thermal efficiency of the burner 22 while saving gas consumption. Furthermore, compared to the large expansion area of a disc-shaped pot rack, which is prone to getting dirty and difficult to clean during cooking, the support ring 100 has a small expansion area, preventing stains from splashing and sticking, and improving the ease of cleaning and maintenance of the pot rack.
[0041] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
