Description

Technical Field

[0001] The utility model relates to the technical field of heating, in particular to a uniform heating device for a flat electromagnetic cooker. Background Art

[0002] The heating principle of the induction cooker is the principle of magnetic field induction eddy current heating. The specific process is as follows: there is a wire reel component inside the induction cooker (the wire reel component includes: coil bracket, coil, magnetic sheet, etc.). When high-frequency alternating current passes through the coil, a high-frequency alternating magnetic field is generated. The greater the current, the greater the magnetic field strength. When the bottom of the iron-containing pot is placed on the induction cooker, the pot is in the alternating magnetic field. Since iron is a conductor and has ferromagnetism, when the magnetic lines of force pass through the bottom of the pot, countless small eddy currents are generated inside the bottom of the pot. These eddy currents cause the charged particles such as iron atoms in the pot itself to move at high speed and rub against each other. The friction of the eddy currents inside the ferromagnetic pot will generate a large amount of heat energy, thereby causing the pot to heat up rapidly. After the pot body heats up, it heats the food in the pot.

[0003] The existing flat induction cooker operates in a high-frequency alternating magnetic field. The magnetic lines of force generated by the induction cooker coil components are uneven. When the flat induction cooker is heated, the center of the pan heats up, and the temperature of the outer circle is low. A donut-shaped high-temperature area with a certain diameter extending outward from the center of the induction cooker coil is formed. The pan heats up significantly unevenly, with a large temperature difference and difficult to control the firepower. If the induction cooker power is turned up high, the food is easily burnt, while if the power is turned down low, the food lacks the aroma of the wok. Due to this characteristic of the induction cooker, people have the impression that food cooked with an induction cooker is not as delicious as food cooked with gas. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a uniform heating device for a flat induction cooker to solve the technical problems of large temperature difference between the center and the edge when heating a frying pan; difficulty in users to accurately control the size of the fire during cooking; and poor food cooking effect caused by uneven heating.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a uniform heating device for a flat induction cooker, comprising a base and a black crystal plate on the top, an induction cooker main unit is arranged at the top center of the base, a wire drum component for heating is arranged above the induction cooker main unit, the wire drum component is connected to the base via a driving component, and the driving component is used to drive the wire drum component to perform rotational motion;

[0006] The driving component includes a driving mechanism for driving the rotary motion and a supporting mechanism for supporting the driving mechanism. The driving mechanism includes a motor. The output end of the motor is fixedly connected to a first driving rocker arm. One end of the first driving rocker arm is rotatably connected to the wire drum component.

[0007] The bottom sides of the wire drum component are rotatably connected with a second driving rocker arm and a third driving rocker arm. One end of the second driving rocker arm and the third driving rocker arm is rotatably connected to the base. The second driving rocker arm and the third driving rocker arm constitute a supporting mechanism.

[0008] By adopting the above technical solution, the wire reel component is connected to the base through the driving component, and the driving component can drive the wire reel component to rotate, so that the wire reel component can continuously change its position during the heating process, thereby ensuring that all parts of the bottom of the pot can be evenly heated. Compared with the fixed position wire reel in the traditional induction cooker, the heating uniformity is improved, local overheating or underheating is avoided, and the cooking effect is improved.

[0009] Furthermore, a gap is provided between the wire reel component and the black crystal plate, and the gap is 0.5 to 60 mm, and the induction cooker main unit and the wire reel component are electrically connected via a wire.

[0010] By adopting the above technical solution, the setting of the gap avoids direct contact between the wire drum components and the black crystal plate, reducing equipment damage or safety hazards caused by friction or high temperature. The use of wires also ensures the safety and stability of current during transmission, avoiding equipment failure or safety accidents caused by excessive or unstable current.

[0011] Furthermore, the first driving rocker arm, the second driving rocker arm and the third driving rocker arm each include a first vertical pole, a connecting piece and a third vertical pole.

[0012] By adopting the above technical solution, the first vertical pole and the third vertical pole serve as the supporting parts of the rocker arm, which can ensure that the rocker arm maintains a stable posture during rotation and is not prone to deformation or shaking. The connecting piece serves as a component connecting the first vertical pole and the third vertical pole, ensuring the stability of the entire rocker arm structure, so that the driving component can more accurately control the rotation position and speed of the wire drum component, thereby achieving a more uniform heating effect.

[0013] Furthermore, the first upright pole and the third upright pole are respectively fixed on different surfaces at both ends of the connecting piece, and the length of the connecting piece is used to adjust the stroke of the rotary motion.

[0014] By adopting the above technical solution, the driving rocker arm can have a more flexible and controllable stroke during rotational motion. Since the connecting piece can be selected in different lengths, the user can select the first driving rocker arm, the second driving rocker arm and the third driving rocker arm with connecting pieces of different lengths according to actual needs to adjust the rotation range and speed of the wire drum component, thereby achieving more precise heating control.

[0015] Furthermore, a shell is provided around the base, and the shell and the black crystal plate are bonded by high-temperature glue.

[0016] By adopting the above technical solution, the setting of the shell enhances the structural strength and stability of the entire device. The shell serves as the external protective layer of the induction cooker, which can effectively prevent external impact and damage, while supporting and fixing the internal components, ensuring the stability and reliability of the induction cooker during long-term use.

[0017] Furthermore, the motor is fixedly connected to the base via a fixed bracket to provide support for the motor.

[0018] By adopting the above technical solution, the stability and firmness of the motor are enhanced. The fixed bracket serves as a connecting bridge between the motor and the base. The fixed bracket adopts an open symmetrical structure, which can evenly disperse the vibration and force generated by the motor and effectively prevent the motor from shaking or shifting during operation.

[0019] Furthermore, the black crystal plates are provided in two types, including a flat black crystal plate and a concave black crystal plate.

[0020] By adopting the above technical solution, flat black crystal plates are suitable for flat-bottomed pots, while concave black crystal plates are more suitable for concave-bottomed pots. Users can choose appropriate black crystal plates according to the type of pots used to ensure the best heating effect and cooking experience.

[0021] In summary, the present invention has the following beneficial effects:

[0022] 1. The utility model provides an induction cooker main unit, a wire reel component, and a driving component, and uses a motor-driven rocker arm kit to adjust the position of the induction cooker wire reel, thereby achieving a uniform heating effect and realizing uniform heating of the bottom of the pan, avoiding the problem of uneven heating in traditional induction cookers. At the same time, users do not need to frequently manually adjust the position of the pot, simplifying the operation process and improving cooking efficiency. Uniform heating helps to better preserve the original flavor and nutritional components of the ingredients, improves the cooking quality of the food, and improves adaptability. It is not only suitable for home kitchens, but can also be widely used in commercial kitchens, catering industries, and other scenarios requiring efficient and precise heating.

[0023] 2. This utility model improves the compatibility and practicality of the induction cooker by providing both flat and concave black crystal plates. When using the induction cooker, users can select the appropriate black crystal plate based on the type of cookware (frying pan or wok) used, ensuring the best heating effect and cooking experience. This can meet the needs of more diverse users and improve the device's applicability and market competitiveness. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0030] The following describes an embodiment of the present invention based on its overall structure.

[0031] Example 1:

[0032] A uniform heating device for a flat electromagnetic cooker, such as Figures 1-4 As shown, it includes a base 1 and a black crystal plate 9 on the top. An induction cooker main unit 8 is provided at the top center of the base 1. A wire reel component 4 for heating is provided above the induction cooker main unit 8. The wire reel component 4 is connected to the base 1 through a driving component 3, and the driving component 3 is used to drive the wire reel component 4 to rotate.

[0033] The driving component 3 includes a driving mechanism 31 for driving the rotary motion and a supporting mechanism 32 for supporting the driving mechanism 31. The driving mechanism 31 includes a motor 301. The output end of the motor 301 is fixedly connected to a first driving rocker arm 302. One end of the first driving rocker arm 302 is rotatably connected to the wire drum component 4.

[0034] The bottom sides of the wire drum component 4 are rotatably connected with the second driving rocker arm 303 and the third driving rocker arm 304. One end of the second driving rocker arm 303 and the third driving rocker arm 304 is rotatably connected to the base 1. The second driving rocker arm 303 and the third driving rocker arm 304 form a supporting mechanism 32. The driving component 3 adopts the motor 301 as the power source. The first driving rocker arm 302 is rotatably connected to the wire drum component 4, and the second driving rocker arm 303 and the third driving rocker arm 304 are rotatably connected to the base 1, so as to realize the stable rotation of the wire drum component. It is not only simple and reliable, but also can ensure that the wire drum component 4 remains stable during the rotation process, and the heating effect will not be affected by shaking or offset. The motor-driven method also makes it easier to realize automatic control of the device, thereby improving the convenience and intelligence of use.

[0035] See Figure 2 and Figure 3 A gap 11 is provided between the wire reel component 4 and the black crystal plate 9, and the gap 11 is 30 mm. The induction cooker main unit 8 and the wire reel component 4 are electrically connected through a wire 10. The existence of the gap 11 forms a certain space between the black crystal plate 9 and the wire reel component 4, which is convenient for users to clean and maintain the black crystal plate in the future. The gap 11 and the wire 10 enable the device to adapt to pots of different thicknesses and materials. Due to the existence of the gap, the magnetic lines of force can more fully penetrate the bottom of pots of different thicknesses and produce an eddy current effect; and the use of the wire 10 ensures that the current can be stably transmitted to the wire reel component and generate a stable high-frequency alternating magnetic field, thereby achieving uniform heating of pots of different materials.

[0036] See Figure 2 and Figure 3 The first driving rocker arm 302, the second driving rocker arm 303 and the third driving rocker arm 304 all include a first vertical rod 51, a connecting piece 52 and a third vertical rod 53. By replacing the connecting pieces 52 with different lengths, different rotation modes can be achieved to adapt to different heating requirements, making the device applicable to more types of cookware, thereby improving the versatility and flexibility of the equipment.

[0037] See Figure 2 and Figure 3 The first vertical rod 51 and the third vertical rod 53 are respectively fixed on different surfaces at both ends of the connecting piece 52, and the length of the connecting piece 52 is used to adjust the stroke of the rotary motion. The first vertical rod 51 and the third vertical rod 53 are respectively fixed on different surfaces at both ends of the connecting piece 52, which enhances the stability and durability of the driving rocker arm. Since the connection between the vertical rod and the connecting piece 52 is firmer and more stable, the driving rocker arm can maintain stable performance under long-term and high-load working conditions and is not prone to deformation or damage.

[0038] See Figure 2 and Figure 3 The base 1 is surrounded by a shell 6, which is bonded to the black crystal plate 9 by high-temperature glue. The shell 6 and the black crystal plate 9 are bonded by high-temperature glue, which not only ensures a close connection between the two, but also improves the sealing and waterproof performance of the induction cooker. As a special adhesive, high-temperature glue can maintain stable performance in a high-temperature environment and is not easy to age or fall off, so that the black crystal plate can be firmly fixed to the shell, avoiding loosening or falling off due to long-term use or external force impact.

[0039] See Figure 2 and Figure 3 The motor 301 is fixedly connected to the base 1 through a fixing bracket 7. The fixing bracket is used to provide support for the motor 301. The fixing bracket adopts an open symmetrical structure. In this embodiment, a "door" type structure is adopted to optimize the heat dissipation conditions of the motor. Since the motor will generate a certain amount of heat when working, the open structure forms a certain space between the bracket and the motor, which is conducive to air circulation and heat dissipation.

[0040] The implementation principle of the present invention is as follows: first, place the base 1 steadily on the desktop to ensure that the device is stable and does not shake, place the flat-bottomed pot in the center of the black crystal plate 9, and ensure that the bottom of the pot is in full contact with the black crystal plate 9 to achieve the best heating effect, press the power button on the induction cooker host 8, and the motor 301 in the driving component 3 will start automatically, and the first driving rocker arm 302 will drive the wire reel component 4 to rotate, and the second driving rocker arm 303 and the third driving rocker arm 304 cooperate with the first driving rocker arm 302 to provide support and maintain the stability of the induction cooker wire reel component during rotation, and ensure that it moves along the correct path. The rotational movement of the wire reel component 4 enables it to repeatedly pass through different parts of the bottom of the black crystal plate 9 to ensure that all parts of the pot bottom can be heated to avoid local overheating or underheating. Adjust the firepower through the control panel of the induction cooker host for subsequent cooking.

[0041] Example 2:

[0042] See Figure 1 and Figure 4 There are two types of black crystal plates 9, including a flat black crystal plate 91 and a concave black crystal plate 92. The two types of black crystal plates also help to optimize the heating uniformity of the induction cooker. Since pots of different shapes have different placement methods and heating areas on the induction cooker, the use of black crystal plates of different shapes can better match the bottom shape of the pot, so that the magnetic lines of force can penetrate the bottom of the pot more evenly, generating more uniform eddy currents and heat energy distribution.

[0043] The implementation principle of the present invention is as follows: first, a suitable black crystal plate 9, a flat black crystal plate 91 or a concave black crystal plate 92 is selected according to cooking needs, so that it can adapt to two different pot types: a frying pan and an ordinary frying pan.

[0044] Parts not involved in the present invention are the same as those in the prior art or can be implemented by using the prior art, and will not be described in detail here.

[0045] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and purpose of the present invention, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
