Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric furnace plates, in particular to a heat radiation structure of a heating wire of an electric furnace plate. Background Art
[0002] When assembling the heating wire of the electric stove plate, a plane layout and a convex arc layout are generally adopted.
[0003] The heat radiated from each position of the flat-layout heating wire has the same distance. Therefore, when the electric stove is used to place a frying pan, the flat-layout heating wire can ensure that each position of the bottom of the frying pan is heated evenly. However, when the electric stove is used to place an arc-bottomed pot, the height distance of the heat radiated from each position of the flat-layout heating wire is different from that of each position of the bottom of the arc-bottomed pot. The closer the flat-layout heating wire is to the center of the bottom of the arc-bottomed pot, the lower the height is, causing the heat in the center of the arc-bottomed pot to be greater than the heat on the periphery, resulting in uneven heating of the food.
[0004] The heat radiated from each position of the heating wire in the convex arc layout has different height distances. Therefore, when the electric stove plate is used to place an arc-bottomed pot, the heating wire in the convex arc layout can ensure that each position of the bottom surface of the arc-bottomed pot is heated evenly. However, when the electric stove plate is used to place a frying pan, the heat radiated from each position of the heating wire in the convex arc layout has different height distances from each position of the bottom surface of the frying pan. The closer the heating wire in the convex arc layout is to the center of the bottom surface of the frying pan, the higher or lower its height is, causing the heat in the center of the frying pan to be less than or greater than the heat on the periphery, resulting in uneven heating of the food.
[0005] All of the above limit the flexibility of use of the electric stove plate.
[0006] In addition, the heating wire with a convex arc layout has high process requirements and high production costs during production and assembly, and there will also be problems with unstable assembly (such as bulging or even loosening of the heating wire after convex arc assembly), which affects the stability of the heating wire.
[0007] Therefore, further improvement is necessary. Utility Model Content
[0008] The utility model aims to provide a heat radiation structure of a heating wire of an electric furnace plate to overcome the shortcomings of the prior art.
[0009] A heat radiation structure of a heating wire of an electric furnace plate designed for this purpose comprises:
[0010] A furnace body, on which a planar assembly portion is arranged, and a heating wire in a planar layout is wound around the planar assembly portion;
[0011] A heat transfer element, the bottom surface of which is at least partially convex, is disposed on the furnace body and is located above the heating wire;
[0012] The distance between adjacent heating wires in the center area of the furnace body is smaller than the distance between adjacent heating wires in the peripheral area of the furnace body;
[0013] The height distance between the central area of the heat transfer element and the central area of the heating wire is greater than the height distance between the peripheral area of the heat transfer element and the peripheral area of the heating wire.
[0014] The heating wires are diffusely arranged from the center of the furnace body toward the periphery and are arranged in a plurality of regions. The distance between adjacent heating wires in each region gradually increases from the center of the furnace body toward the periphery according to a certain ratio.
[0015] The heating wires are diffusely arranged from the center of the furnace body toward the periphery, and the distance between adjacent heating wires gradually increases from the center of the furnace body toward the periphery.
[0016] A temperature detector is also provided on the furnace body or the heat transfer element.
[0017] One or more temperature detectors are provided.
[0018] The temperature detector is located between adjacent heating wires, and / or the temperature detector is located between the heating wire and the heat transfer element.
[0019] A connecting part is arranged on the furnace body, and the heat transfer element is made of high temperature resistant glass, ceramic, metal, or pot, and is arranged on the connecting part.
[0020] The connecting part is located at the periphery of the plane assembly part and is protruded on the furnace body.
[0021] The temperature detector is arranged on the flat mounting portion and / or the connecting portion.
[0022] A first assembly hole is arranged at the center of the planar assembly part, a second assembly hole is arranged on the connecting part, and two temperature detectors are arranged, one of which is fixedly arranged on the first assembly hole and located between adjacent heating wires in the central area, and the other temperature detector is fixedly arranged on the second assembly hole and located between the heating wires and the heat transfer element in the peripheral area.
[0023] In the present invention, since the spacing between adjacent heating wires located in the central area of the furnace body is smaller than the spacing between adjacent heating wires located in the peripheral area of the furnace body, when the heating wires arranged in a planar manner are working, the overall radiation heat of the central area of the furnace body is greater than the overall radiation heat of its peripheral area, so that when the heat transfer element arranged on the furnace body and with a bottom surface at least partially convex is heated, the heat close to the central area can be equal to the heat close to the peripheral area, thereby ensuring that each position of the heat transfer element with a bottom surface at least partially convex can be evenly heated, so as to achieve the purpose of uniform heating of food.
[0024] In addition, since the heating wire is wound flat on the flat assembly part, the heating wire can be easily and stably assembled, which not only effectively reduces the assembly process of the heating wire, improves production efficiency, reduces defective products, and reduces production costs, but also avoids the problem of bulging or even loosening of the heating wire due to unstable assembly, thereby extending the service life of the electric furnace plate and improving the stability of the use of the electric furnace plate.

[0030] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.
[0031] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0032] See also Figure 1-Figure 5 The heat radiation structure of the heating wire of the electric furnace plate includes
[0033] A furnace body 1 is provided with a plane assembly portion 1.1, and a heating wire 2 in a plane layout is wound around the plane assembly portion 1.1;
[0034] The heat transfer element 3 has a bottom surface at least partially convex, is disposed on the furnace body 1, and is located above the heating wire 2;
[0035] The distance between adjacent heating wires 2 located in the central area of the furnace body 1 is smaller than the distance between adjacent heating wires 2 located in the peripheral area of the furnace body 1;
[0036] The height distance between the central area of the heat transfer element 3 and the central area of the heating wire 2 is greater than the height distance between the peripheral area of the heat transfer element 3 and the peripheral area of the heating wire 2 .
[0037] In this embodiment, since the spacing between adjacent heating wires 2 located in the central area of the furnace body 1 is smaller than the spacing between adjacent heating wires 2 located in the peripheral area of the furnace body 1, when the heating wires 2 arranged in a planar manner are working, the overall radiation heat of the central area of the furnace body 1 is greater than the overall radiation heat of its peripheral area, so that when the heat transfer element 3 arranged on the furnace body 1 and with a bottom surface at least partially convex is heated, the heat near the central area can be equal to the heat near the peripheral area, thereby ensuring that each position of the heat transfer element 3 with a bottom surface at least partially convex can be evenly heated, so as to achieve the purpose of uniform heating of food.
[0038] In addition, since the heating wire 2 is wound in a plane on the flat assembly portion 1.1, the heating wire 2 can be easily and stably assembled, which not only effectively reduces the assembly process of the heating wire 2, improves production efficiency, reduces defective products, and reduces production costs, but also avoids the problem of the heating wire 2 bulging or even loosening due to unstable assembly, thereby extending the service life of the electric furnace plate and improving the stability of the use of the electric furnace plate.
[0039] Specifically, the heating wires 2 are diffusely arranged from the center of the furnace body 1 toward the periphery and arranged in a plurality of regions, and the distance between adjacent heating wires 2 in each region gradually increases from the center of the furnace body 1 toward the periphery at a certain ratio.
[0040] That is, when the heating wire 2 is arranged, a plurality of different areas are arranged at different intervals, wherein the intervals between the heating wires 2 in these different areas gradually increase at a certain ratio from the center of the furnace body 1 toward the outside. In simple terms, the intervals between the heating wires 2 closer to the center of the furnace body 1 are smaller than the intervals between the heating wires 2 farther away from the center of the furnace body 1.
[0041] In addition, the heating wires 2 are diffusely arranged from the center of the furnace body 1 toward the periphery, and the interval between adjacent heating wires 2 gradually increases from the center of the furnace body 1 toward the periphery.
[0042] That is, when the heating wires 2 are arranged, the spacing between the heating wires 2 located at the center of the furnace body 1 gradually increases toward the periphery of the furnace body 1 .
[0043] A temperature detector 4 is also provided on the furnace body 1 or the heat transfer element 3, and the temperature detector 4 is used to detect the temperature of the heating wire 2 when it is working, so as to improve the safety of the product.
[0044] There is one temperature detector 4 or there may be multiple temperature detectors 4 . When there are multiple temperature detectors 4 , they are spaced apart from each other.
[0045] The temperature detector 4 is located between adjacent heating wires 2, thereby directly detecting the temperature between adjacent heating wires 2, and / or, the temperature detector 4 is located between the heating wires 2 and the heat transfer element 3, thereby detecting the temperature radiated from the heating wires 2 to the heat transfer element 3.
[0046] The furnace body 1 is provided with a connection part 1.2, and the heat transfer element 3 is made of high temperature resistant glass, ceramic, metal, or a cooker and is arranged on the connection part 1.2. That is, no matter the heat transfer element 3 is made of high temperature resistant glass, ceramic, metal, or a cooker, it is arranged on the furnace body 1 through the connection part 1.2 to ensure the stable assembly of the heat transfer element 3.
[0047] Among them, Figure 1-Figure 3 As shown, the bottom surface of the heat transfer element 3 is in an overall upward convex arc shape. In addition, as shown in FIG. Figure 5 As shown, the center of the bottom surface of the heat transfer element 3 is flat and the periphery is convex arc-shaped.
[0048] The connecting portion 1.2 is located outside the planar assembly portion 1.1 and protrudes from the furnace body 1. Thus, the protruding connecting portion 1.2 can not only protect the heating wire 2, but also prevent the heat generated by the heating wire 2 during operation from diffusing to the outside of the furnace body 1, thereby improving the safety of the product.
[0049] The temperature detector 4 is arranged on the flat mounting portion 1.1 and / or the connecting portion 1.2.
[0050] In this embodiment, a first assembly hole 1.3 is provided at the center of the planar assembly portion 1.1, a second assembly hole 1.4 is provided on the connecting portion 1.2, and two temperature detectors 4 are provided, one of which is fixedly provided on the first assembly hole 1.3 and located between adjacent heating wires 2 in the central area, and the other temperature detector 4 is fixedly provided on the second assembly hole 1.4 and located between the heating wires 2 and the heat transfer member 3 in the peripheral area. In this way, the two temperature detectors 4 provided at different positions are used to respectively detect the temperature between adjacent heating wires 2 and the temperature radiated from the heating wires 2 to the heat transfer member 3, thereby improving the temperature detection stability and uniformity of the furnace plate.

Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
