Description

Technical Field

[0001] This utility model relates to the field of heating plates, and more particularly to a heating plate structure that generates heat around the entire circle. Background Technology

[0002] The heating plate of the health pot is either a semi-circular heating plate or a square bent heating plate. Both types of heating plates have certain defects.

[0003] The heating element of the semi-circular heating plate is a semi-circular arc shape with a heating gap. The heating element can only heat the food inside the pot, resulting in a longer heating time.

[0004] The heating element of the square bending plate is bent to form a square heating area, while the bottom of the kettle body is circular. This results in the heating area and the heated position not completely overlapping, making it difficult to effectively utilize the area of ​​the heating area and leading to low heating efficiency. It should be noted that the information disclosed in the above background section is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a heating plate structure with a full circle of heating to solve the problems of the prior art where the half circle heating plate can only heat the food inside the pot, resulting in a long heating time, and the square bending plate cannot effectively utilize the heating area, resulting in low heating efficiency.

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

[0007] A heating plate structure that generates heat in the entire ring;

[0008] Includes: a metal disc; a heating plate attached to the metal disc; and a heating element coiled and mounted on the heating plate.

[0009] The heating plate is provided with mounting posts, which are located on the side of the heating tube; the area of ​​the heating surface of the heating tube gradually increases towards the heating plate.

[0010] A further technical solution is that the heating element includes: a tube body and tube heads disposed at both ends of the tube body; wherein, both ends of the tube body are bent away from the heating plate.

[0011] A further technical solution is that a groove is formed on the heating plate; a temperature measuring device is installed in the groove.

[0012] A further technical solution is that the tube body includes: a first arc segment, a second arc segment, a third arc segment, a fourth arc segment, and a fifth arc segment connected in sequence; the first arc segment is arranged along the edge of the heating plate, and the second arc segment bends inward to avoid the temperature measuring device; the fifth arc segment is spaced parallel to the first arc segment, and the interval between the fourth arc segment and the first arc segment narrows; the third arc segment connects the fourth arc segment and the second arc segment respectively.

[0013] A further technical solution is that the diameters of the first arc segment, the third arc segment, and the fifth arc segment are the same; the diameter of the second arc segment is smaller than the diameter of the first arc segment; and the plane rotation angle between the pipe heads at both ends of the pipe body is greater than 450°.

[0014] A further technical solution is that the parallel interval between the fifth arc segment and the first arc segment is 15-19mm.

[0015] A further technical solution is that the metal disc is a steel disc; the heating plate is an aluminum plate; and the heating plate is provided with a plurality of mounting posts, which are located between the first arc segment, the second arc segment, the third arc segment, the fourth arc segment, and the fifth arc segment.

[0016] A further technical solution is that a pressure cap is fitted onto the pipe head, and the pressure cap is connected to the pipe body.

[0017] A further technical solution is that the outer perimeter of the cross-sectional width of the heating element is 3-5mm.

[0018] Compared with the prior art, the beneficial technical effects of this utility model are as follows: (1) When the heating tube becomes loose, the range of the heating tube is limited by the mounting column; the heating tube is prevented from contacting other parts of the pot body; the shape of the heating tube increases the contact area between the heating tube and the heating plate, so that the heat of the heating tube can be transferred to the heating plate over a large area to achieve rapid heating; at the same time, the distance between the heating tubes is increased, the heating tubes are more evenly distributed, the problem of concentrated heating is reduced, and the continuous air explosion noise caused by water vapor separation due to concentrated heat is suppressed.

[0019] (2) To ensure a smooth transition between the third and fifth arc segments, the fourth arc segment is elliptical in shape; the fourth arc segment ensures that after the tube body is continuously bent, the bending position transitions evenly, and the heating wires inside the tube body are stretched to a uniform degree, so that the tube body heats up evenly.

[0020] (3) The plane rotation angle between the tube ends of the tube body is greater than 450°, so that the tube body continues to be rolled a distance after one turn, avoiding the occurrence of heating blind spots; at the same time, the heating blind spot in the middle of the heating plate is reduced, and the heating area of ​​the tube body is increased.

[0021] (4) The diameter of the pressure cap is larger than the diameter of the tube head to prevent the tube head from being affected by heat when it comes into contact with the heating plate; the pressure cap is used to press the tube head tightly so that the tube head is securely fixed to the tube body and to prevent loosening.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the device proposed by this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of this utility model will become clearer according to the following description.

Please refer to the accompanying drawings to make the objectives, features, and advantages of this utility model more apparent and understandable. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are only used to complement the content disclosed in the specification, for those skilled in the art to understand and read, and are not intended to limit the implementation conditions of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportional relationships, or adjustments to the size, without affecting the effects and objectives that this utility model can produce, should still fall within the scope of the technical content disclosed in this utility model.

[0026] Figure 1 The diagram shows a bottom view of the heating plate structure with full-circle heating according to an embodiment of the present invention. Figure 2 An exploded view of the heating plate structure with full-circle heating according to an embodiment of this utility model is shown. (Combined with...) Figure 1 and Figure 2 As shown, this utility model discloses a heating plate structure with full-circle heating.

[0027] The heating plate structure with full-circle heating includes a metal plate 1, a heating plate 2 horizontally attached above the metal plate 1, and a heating tube 3 rolled up and set on the heating plate 2.

[0028] The heating plate 2 is connected to the metal plate 1 by furnace welding or brazing. The heating element 3 is connected to the heating plate 2 by furnace welding or brazing.

[0029] Mounting posts 21 are provided vertically on the upper surface of the heating plate 2, located on the side of the heating element 3. When the heating element 3 becomes loose, the mounting posts 21 restrict its movement, preventing contact between the heating element 3 and other parts of the kettle body.

[0030] The heating surface area of ​​the heating tube 3 gradually increases towards the heating plate 2. The width of the cross-section of the heating tube 3 also gradually increases towards the heating plate 2, making its cross-sectional shape nearly trapezoidal. This shape increases the contact area between the heating tube 3 and the heating plate 2, allowing heat from the heating tube 3 to be transferred to the heating plate 2 over a larger area, achieving rapid heating. Simultaneously, the increased spacing between the heating tubes results in a more uniform distribution, reducing heat concentration issues and thus suppressing continuous air-burst noise caused by water vapor separation due to heat concentration.

[0031] The cross-sectional width of the heating element 3 is 3-5mm. By limiting the cross-sectional width of the heating element 3, large changes in the structural spacing of the heating element 3 are avoided, ensuring that the structure of the heating element 3 is kept at a certain interval. This prevents the structure of the tube body 31 from being too concentrated, causing local overheating, and also prevents the structure of the tube body 31 from being too dispersed, which would affect the heating efficiency.

[0032] The heating element 3 includes a tube body 31 and tube heads 32 disposed at both ends of the tube body 31. The tube heads 32 are connected to a power source. The tube body 31 transfers heat to the heating plate 2. To prevent the heat from the heating plate 2 from affecting the tube heads 32, both ends of the tube body 31 are bent away from the heating plate 2. This creates a distance between the two ends of the tube body 31 and the heating plate 2, preventing the tube heads 32 from contacting other parts of the kettle body and causing leakage.

[0033] A groove 4 is formed on the heating plate 2, and a temperature measuring device is fixedly installed in the groove 4 using a single stud or a double stud. For example, the temperature measuring device is an NTC probe. The groove 4 can be formed at the outer edge of the heating plate 2. The groove 4 can also be formed in the middle of the heating plate 2.

[0034] The tube body 31 includes a first arc segment 311, a second arc segment 312, a third arc segment 313, a fourth arc segment 314, and a fifth arc segment 315 connected in sequence.

[0035] The first arc segment 311 is positioned along the edge of the heating plate 2. Its relatively long length allows it to heat food within the inner edge of the pot. The second arc segment 312 bends inward to avoid the temperature measuring device, and also prevents the fourth and fifth arc segments 314 and 315 from overlapping with the first arc segment 311. One end of the second arc segment 312 connects to the first arc segment 311, and the other end bends inward to avoid the groove 4 before connecting to the third arc segment 313.

[0036] The fifth arc segment 315 is parallel to the first arc segment 311 to prevent the tube head 32 from being affected by heat due to its proximity to the first arc segment 311. The interval between the fourth arc segment 314 and the first arc segment 311 narrows. The third arc segment 313 is parallel to the first arc segment 311 and connects the fourth arc segment 314 and the second arc segment 312. To ensure a smooth transition between the third arc segment 313 and the fifth arc segment 315, the fourth arc segment 314 is elliptical in shape. The fourth arc segment 314 ensures that after continuous bending of the tube body 31, the bending position transitions evenly, and the heating wire inside the tube body 31 is stretched uniformly, resulting in uniform heating of the tube body 31.

[0037] The diameters of the first arc segment 311, the third arc segment 313, and the fifth arc segment 315 are the same. The first arc segment 311, the third arc segment 313, and the fifth arc segment 315 are parallel to each other, ensuring that the heating wire inside the tube 31 is stretched to a consistent degree, so that the tube 31 heats up evenly.

[0038] The diameter of the second arc segment 312 is smaller than that of the first arc segment 311. During the inward bending process of the second arc segment 312, it is necessary to ensure that the groove 4 is avoided, while ensuring the stretching degree of the heating wire inside the tube body 31. By reducing the diameter of the second arc segment 312, the stretching degree of the heating wire inside the tube body 31 can be ensured to be consistent while avoiding the groove 4.

[0039] The plane rotation angle between the tube ends 32 at both ends of the tube body 31 is greater than 450°, so that the tube body 31 continues to bend a certain distance after rolling one turn, avoiding the occurrence of heating blind spots. At the same time, it reduces the heating blind spot in the middle of the heating plate 2 and increases the heating area of ​​the tube body 31.

[0040] The fifth arc segment 315 and the first arc segment 311 are parallel and spaced 15-19mm apart. Maintaining a certain distance between the fifth arc segment 315 and the first arc segment 311 avoids the structure of the tube body 31 being too concentrated, which could cause local overheating, and also avoids the structure of the tube body 31 being too dispersed, which could affect the heating efficiency.

[0041] For example, the metal pan 1 is a steel pan. For example, the heating plate 2 is an aluminum plate. The tube 31 heats the heating plate 2, and the heat is evenly distributed on the heating plate 2. The heating plate 2 transfers the heat to the metal pan 1, and the metal pan 1 heats the food in the pot as a whole, avoiding localized heating of the food.

[0042] The heating plate 2 is provided with multiple mounting posts 21, which are located between the first arc segment 311, the second arc segment 312, the third arc segment 313, the fourth arc segment 314, and the fifth arc segment 315. There is a distance between the mounting posts 21 and the side of the heating element 3. The mounting posts 21 limit the range of the heating element 3 and prevent the heating element 3 from contacting other parts of the kettle body.

[0043] A pressure cap 33 is fitted onto the tube head 32, and the pressure cap 33 connects to the tube body 31. The diameter of the pressure cap 33 is larger than the diameter of the tube head 32 to prevent the tube head 32 from being affected by heat in contact with the heating plate 2. The pressure cap 33 is connected to the tube body 31 by a threaded connection or a crimping connection, and the pressure cap 33 presses the tube head 32 tightly, so that the tube head 32 is securely fixed to the tube body 31 and prevents it from loosening.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
