Description

Technical Field

[0001] The utility model relates to the technical field of heating plates for electromagnetic cookers, and more specifically to a square closely wound heating plate. Background Art

[0002] Induction cookers use the principle of magnetic field induction eddy currents. High-frequency currents pass through a toroidal coil, generating numerous closed magnetic fields. When the magnetic lines of force pass through the bottom of the magnetic conductor, they generate numerous small eddy currents, causing the pot to heat up at high speed, which in turn heats the food inside. The heating coil is a key component of the induction cooker.

[0003] Existing induction cookers use circular coiled heating coils, which can evenly heat circular boilers. However, for square or other non-circular cookware, the matching degree of the heating area is low, and there may be a heating blind spot at the bottom of the non-circular boiler, resulting in reduced heating efficiency. In addition, the induction cooker is designed to be rectangular, and the circular coil is coiled inside the rectangular induction cooker, which has low space utilization and a certain amount of space waste, which is not conducive to the miniaturization and lightweight design of the product. Therefore, a square tightly wound heating coil that is suitable for different boilers is needed.

[0004] In view of this, the utility model provides a square tightly wound heating plate. Utility Model Content

[0005] The purpose of the present utility model is to solve the above-mentioned shortcomings and provide a square closely wound heating plate adapted to different boilers.

[0006] The heating coil is coiled in a rounded square shape, which can evenly heat pots with different bottom shapes and increase the heating area of ​​the induction cooker of the same volume.

[0007] Therefore, the utility model provides a square tightly wound heating plate, including an induction cooker shell, the outer shape of the induction cooker shell is set to be polygonal, which saves space and is characterized in that: two wire grooves are provided inside the induction cooker shell, and the inner coils of the two wire grooves are connected to the inner heating coil and the outer heating coil, and the inner heating coil and the outer heating coil are both set to be rounded squares. The inner heating coil and the outer heating coil can heat the bottoms of different pots more efficiently, and have a higher space occupancy rate inside the induction cooker shell, a larger heating area can be heated, and the heating blind area is reduced.

[0008] As a further improvement of the present technical solution, a plurality of support blocks are installed at the bottom of the induction cooker shell. The plurality of support blocks at the bottom of the induction cooker shell can make the induction cooker shell more stable.

[0009] As a further improvement of the present technical solution, a connecting wire head is installed at the bottom of the induction cooker shell, and the connecting wire head is electrically connected to the inner heating coil and the outer heating coil. The connecting wire head can control the operation and heating of the inner heating coil and the outer heating coil.

[0010] As a further improvement of the present technical solution, a temperature-sensing NTC penetrating the middle of the inner heating coil is installed on the top of the induction cooker shell. The temperature-sensing NTC can monitor the temperature of the heat energy emitted by the inner and outer heating coils in real time to achieve precise temperature control.

[0020] Existing induction cookers use circular coiled heating coils, which can evenly heat circular boilers. However, for square or other non-circular cookware, the matching degree of the heating area is low, and there may be a heating blind spot at the bottom of the non-circular boiler, resulting in reduced heating efficiency. In addition, the induction cooker is designed to be rectangular, and the circular coil is coiled inside the rectangular induction cooker, which has low space utilization and a certain amount of space waste, which is not conducive to the miniaturization and lightweight design of the product. Therefore, a square tightly wound heating coil that is suitable for different boilers is needed.

[0021] like Figure 1-4 As shown, the device includes an induction cooker shell 1. The outer shape of the induction cooker shell 1 is set to be polygonal to save space. Two wire grooves are opened inside the induction cooker shell 1. The inner heating wire drum 2 and the outer heating wire drum 3 are connected and coiled inside the two wire grooves. The inner heating wire drum 2 and the outer heating wire drum 3 are both set to be rounded square. The inner heating wire drum 2 and the outer heating wire drum 3 can heat the bottom of different boilers more efficiently, and have a higher space occupancy rate inside the induction cooker shell 1, a larger heating area can be heated, and the heating blind area is reduced.

[0022] It's important to note that the induction cooker housing, with its top heating surface constructed of mica, offers excellent insulation and high-temperature resistance. The internal frame of the housing is constructed with a magnetic strip mounting framework, which better aligns with the heating area of ​​the induction cooker, ensuring a more even distribution of magnetic flux and enhancing the heating effect. The above structure is prior art, and its operating principles are common knowledge to those skilled in the art, so I won't elaborate on them here.

[0023] A plurality of support blocks 11 are installed at the bottom of the induction cooker housing 1 . The plurality of support blocks 11 at the bottom of the induction cooker housing 1 can make the induction cooker housing 1 more stable.

[0024] It's important to note that the support blocks are made of high-frequency magnetic strips, which effectively guide and concentrate the magnetic field. This improves magnetic field efficiency and enhances signal transmission and energy conversion. The above structure is prior art, and its operating principles are common knowledge to those skilled in the art, so I won't elaborate on them here.

[0025] By winding the inner heating wire drum 2 and the outer heating wire drum 3 in the shape of a rounded square in the two wire grooves inside the induction cooker shell 1, the inner heating wire drum 2 and the outer heating wire drum 3 with rounded square can cover a larger area in the horizontal direction. For cookware that requires uniform heating over a large area, such as a square frying pan, they can better fit the shape of the bottom of the pot, heat more evenly, and reduce heating blind spots. In addition, the inner heating wire drum 2 and the outer heating wire drum 3 with rounded square can better match the space inside the induction cooker shell 1, making the overall layout more compact, which is conducive to reducing the volume and thickness of the induction cooker shell 1, making the product lighter and more portable.

[0026] The internal circuit connection of the inner heating coil 2 and the outer heating coil 3 is an existing technology. The heating coil adopts the principle of magnetic field induction eddy current, and uses high-frequency current to pass through the inner heating coil 2 and the outer heating coil 3, which are coiled in a rounded square shape, to generate countless closed magnetic field forces. When the magnetic lines of force of the magnetic field pass through the bottom of the magnetic conductor, countless small eddy currents will be generated, causing the pot body itself to heat up at high speed, and then heat the food in the pot.

[0027] Combine Figure 2-3 As shown, a connecting wire head 4 is installed at the bottom of the induction cooker shell 1, and the connecting wire head 4 is electrically connected to the inner heating coil 2 and the outer heating coil 3. The connecting wire head 4 can control the heating of the inner heating coil 2 and the outer heating coil 3. For pots of different sizes, the square heating area formed by the inner heating coil 2 and the outer heating coil 3 can be evenly heated.

[0028] The inner heating coil 2 and the outer heating coil 3 are connected by different connecting wire heads 4, so that the connecting wire heads 4 can power the inner heating coil 2 and the outer heating coil 3, and turn on the inner heating coil 2 and the outer heating coil 3 to heat at different temperatures and powers to meet diverse cooking modes. For pots of different sizes, the square heating area formed by the inner heating coil 2 and the outer heating coil 3 can be evenly heated to ensure the heating effect and improve energy utilization efficiency.

[0029] Considering again the problem of how to monitor the heat inside the heating coil when the induction cooker is heating, combined with Figure 1-Figure 2 As shown, a temperature-sensing NTC 5 is installed on the top of the induction cooker housing 1 and penetrates the middle of the inner heating coil 2. The temperature-sensing NTC 5 can monitor the temperature of the heat energy emitted by the inner heating coil 2 and the outer heating coil 3 in real time to achieve precise temperature control.

[0030] When the inner heating coil 2 and the outer heating coil 3 are powered on, the temperature-sensing NTC5 monitors the temperature of the induction cooker and the temperature of key parts such as the coils in real time. By detecting temperature changes, it ensures that the induction cooker operates within a safe temperature range to prevent dangers caused by excessive temperature, such as overheating and damage to the stove surface, fire, etc. According to the temperature information fed back by the temperature-sensing NTC5, the control system of the induction cooker can adjust the power output to achieve precise temperature control. During the cooking process, when the temperature reaches the set value, the control system will reduce the power output to keep the temperature stable; when the temperature is lower than the set value, the power output will be increased to raise the temperature.

[0031] In summary, the working principle of this solution is as follows:

[0032] When using the induction cooker, the connecting wire head 4 is used to power on the induction cooker, which can control the inner heating wire reel 2 and the outer heating wire reel 3 that are coiled in a square shape with rounded corners to heat up. The inner heating wire reel 2 and the outer heating wire reel 3 that are coiled in a square shape with rounded corners can cover a larger area in the horizontal direction. For pots that require uniform heating over a large area, such as square frying pans, they can better fit the shape of the bottom of the pot, heat more evenly, and reduce heating blind spots.

[0033] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
