The heating plate resistor structure comprises multiple layers of resistors 1 with different arc lengths distributed along the radial direction and interconnected to form a disk-shaped distribution. The resistors 1 are divided into heating zones a, b, c, d, e, f, g, and h with the center of the disk as the center.

Description

Technical Field

[0001] This utility model relates to the field of electric heating components, specifically a circular thick-film heating plate resistor structure and heating plate. Background Technology

[0002] When heating viscous ingredients such as milk or soy products in powder or solution form, the high content of fats and oils can easily cause them to stick or burn due to excessive heat. Therefore, during heating, a motor rotor drives an internal stirrer to create turbulence, exchanging hot and cold liquids to ensure even heating. However, this rotation and turbulence can lead to uneven heat distribution at the bottom of the heating plate and irregular flow of the ingredients. Consequently, some ingredients remain at the bottom, absorbing excessive heat and becoming sticky or burnt. This alters the nutritional value and texture of the heated ingredients, and the burnt residue is difficult to clean thoroughly. Summary of the Invention

[0003] To address the aforementioned technical problems, this utility model proposes a circular thick-film heating plate resistor structure and a heating plate. The technical problem to be solved by this utility model is achieved through the following technical solution:

[0004] A circular thick-film heating plate resistor structure includes multiple layers of resistors with different arc lengths distributed along the radial direction and interconnected to form a disk-shaped distribution. The resistors are divided into heating areas a, b, c, d, e, f, g, and h with the center of the disk-shaped heating area as the center. Each resistor includes a first resistor segment covering the heating areas a, b, c, d, e, f, g, and h. The first resistor segment is connected to a second resistor segment distributed along the radial direction to cover the heating areas a, b, c, d, e, f, g, and h. The arc lengths of the second resistor segments are all different. The second resistor segment is connected to a third resistor segment and a fourth resistor segment symmetrically arranged along the radial direction of the disk-shaped center.

[0005] The first resistor segment includes a first arc-shaped resistor with one end open and two second arc-shaped resistors distributed in a circle around the center of the disk. The first arc-shaped resistor has a first connection terminal at the opening, and one end of each second arc-shaped resistor segment is connected to the first connection terminal.

[0006] The second resistor segment includes three layers of third arc-shaped resistors distributed along the radial direction, wherein the first and second layers of the third arc-shaped resistors are provided with second connection terminals;

[0007] The third resistor segment includes a fourth arc-shaped resistor symmetrically arranged along the vertical direction of the disc-shaped center diameter and a fifth arc-shaped resistor connecting the two fourth arc-shaped resistors. The fourth arc-shaped resistor has four layers and the arc length of each layer is not equal. The fourth arc-shaped resistor is connected to two third connection terminals.

[0008] The first connecting end, the second connecting end, and the third connecting end are distributed in parallel along the vertical direction of the disk-shaped center diameter, and the first connecting end and the third connecting end are distributed on the same side.

[0009] The resistance thickness is determined by the formula P=I 2 The pL / S calculation is performed, where p is the square resistance of the product, S is the three-dimensional cross-sectional area of ​​the circuit, and L is the length of the resistive circuit.

[0010] A heating plate employing the aforementioned circular thick-film heating plate resistor structure further includes a substrate, the substrate and the circular thick-film heating plate resistor structure, with an insulating layer and a conductor layer 8 distributed between them, and a protective layer sintered on top of the circular thick-film heating plate resistor structure.

[0011] The beneficial effects of this invention are as follows: The product is an eccentric rotor, which applies different speeds and impact forces to different parts of the food during rotation. The impact forces in the near-rotation areas A, B, C, D, G, and H are relatively similar, but the impact forces in areas E and F are weaker due to their greater distance, causing the product to remain stationary in these areas for a slightly longer time. To ensure that the total amount of heat energy absorbed by the food is minimized, the power consumption in these areas is reduced. Therefore, the first and third connecting ends are located in areas e and f. Simultaneously, in areas a and b, the width of the resistance lines is reduced, and the amount of resistance line S is decreased to increase functionality. In areas e and f, the width of the resistance line S is increased, and the length of the resistance line L is shortened to reduce power consumption. This allows for a more reasonable distribution of heat effects and reduces scorching. Attached Figure Description

[0021] like Figures 1 to 6 As shown, a circular thick-film heating plate resistor structure includes multiple layers of resistors 1 with different arc lengths distributed along the radial direction and interconnected to form a disk-shaped distribution. The resistors 1 are divided into heating areas a, b, c, d, e, f, g, and h with the center of the disk-shaped heating area as the center. The resistors 1 include a first resistor segment 2 covering the heating areas a, b, c, d, e, f, g, and h. The first resistor segment 2 is connected to a second resistor segment 3 distributed along the radial direction to cover the heating areas a, b, c, d, e, f, g, and h. The arc lengths of the second resistor segment 3 are not equal. The second resistor segment 3 is connected to a third resistor segment 4 and a fourth resistor segment 5 symmetrically arranged along the radial direction of the disk-shaped center.

[0022] The first resistor segment 2 includes a first arc-shaped resistor 21 with one end open and two second arc-shaped resistors 22 distributed in a circular pattern around the center of the disk. The first arc-shaped resistor 21 has a first connection end 23 at the opening, and one end of each second arc-shaped resistor 22 is connected to the first connection end 23.

[0023] The second resistor segment 3 includes three layers of third arc-shaped resistors 31 distributed along the radial direction, wherein the first and second layers of the third arc-shaped resistors 31 are provided with second connection terminals 32.

[0024] The third resistor segment 4 includes a fourth arc-shaped resistor 41 symmetrically arranged along the vertical direction of the disk-shaped center diameter, and a fifth arc-shaped resistor 42 connecting the two fourth arc-shaped resistors 41. The fourth arc-shaped resistor 41 has four layers and the arc length of each layer is not equal. The fourth arc-shaped resistor 41 is connected to two third connection terminals 43.

[0025] The first connecting end 23, the second connecting end 32, and the third connecting end 43 are distributed in parallel along the vertical direction of the disk-shaped center diameter, and the first connecting end 23 and the third connecting end 43 are distributed on the same side.

[0026] The fourth resistor segment 5 includes sixth arc-shaped resistors 51 symmetrically distributed along the horizontal direction in a disk-shaped center diameter. Each sixth arc-shaped resistor 51 is provided with four layers, and the arc length of each layer is not equal. The sixth arc-shaped resistor 51 is connected to an electrode 52. An external power supply is connected through the electrode 52. As shown in the figure, the area enclosed by the fourth resistor segment 5 and the second resistor segment 3 avoids the eccentric mounting hole 10.

[0027] The sixth arc-shaped resistor 51 on one side is connected to the third resistor segment 4, and the sixth arc-shaped resistor 51 on the other side is connected to the second resistor segment 3.

[0028] like Figures 4 to 6 As shown, the eccentric mounting hole 10 is the mounting location for the eccentric rotor, which drives the food to rotate, forming a shape like... Figure 6 As shown in the trajectory, the impact forces in the near-rotation regions A, B, C, D, G, and H are not significantly different. However, the impact forces in regions E and F are weaker due to their greater distance, resulting in the product remaining stationary in these regions for a slightly longer time. To ensure that the total amount of heat energy absorbed by the food is minimized, the power consumption in these areas will be reduced. The resistance distribution will be designed as follows... Figure 4 The distribution is shown. The first connection terminal 23 and the third connection terminal 43 are designed in the regions f and e to reduce the power in this region and reduce the phenomenon of food sticking to the bottom and burning.

[0029] The thickness of resistor 1 is determined by the formula P=I. 2 The pL / S calculation involves p being the square resistance of the product, S being the cross-sectional area of ​​the circuit, and L being the length of the resistive circuit. Given the similar power requirements in each region, it's observed that the heating wires in regions e and f need to be made as thick as possible while their total length is shortened. To ensure the power of the eight regions remains within a 20% deviation, regions a and b are increased by reducing the width of the heating wires and decreasing the amount of S, while regions e and f are decreased by increasing S and shortening L.
