[0001] This utility model relates to the field of heating plate technology, and specifically to a high-efficiency heating plate. Background Technology
[0002] A heating plate is an electric heating plate in various shapes, consisting of a heating coil encased in a thin metal plate (aluminum, stainless steel, etc.). The heating element is cast into, welded to, or embedded in the aluminum plate. Typical applications include rice cookers and induction cookers.
[0003] Existing heating plates have heating coils located inside the outer casing. As a result, heat must pass through the casing to heat objects placed on the heating plate. However, heat loss occurs during this process, affecting heating efficiency and hindering the rapid heating of objects. This impacts the heating effect and performance of the device. Therefore, there is an urgent need for a more efficient heating plate to solve these problems. Summary of the Invention
[0004] (a) Technical problems to be solved
[0005] The technical problem to be solved by this utility model is to provide a heating plate that can reduce heat loss, has high heating efficiency, good heating effect and high performance, in light of the current state of the technology.

[0007] This utility model is achieved through the following technical solution: This utility model proposes a high-efficiency heating plate, including a shell, a heating coil installed inside the shell, a cover plate fixed to the top of the shell, five sets of through cavities distributed in a circle on the cover plate, a rotating column installed in the through cavity, multiple sets of guide cavities arrayed on the rotating column, a bearing ring fixed to the outside of the cover plate, five sets of drive motors distributed in a circle inside the bearing ring, and a sealing cover provided above the drive motor.
[0008] Furthermore, the heating coil is fixed inside the housing, and the cover plate is fixed to the top of the housing by screws.
[0009] By adopting the above technical solution, the outer shell and the cover plate can hide the heating coil, which can generate heat to heat the object when energized.
[0010] Furthermore, the cavity is formed on the cover plate, and the rotating column is rotatably installed inside the cavity.
[0011] By adopting the above technical solution, the through cavity provides rotation space for the rotating column. When the device is idle, the rotating column can hide the flow guide cavity and thus seal the through cavity. During use, the rotating column can be rotated 90 degrees to expose the flow guide cavity.
[0012] Furthermore, the flow guide cavity is formed on the rotating column, and the outer diameter of the rotating column matches the inner diameter of the through cavity.
[0013] By adopting the above technical solution, during the heating process, part of the heat generated by the heating coil can directly heat the object through the guide cavity, avoiding a large loss as it all passes through the cover plate, thus effectively improving the heating efficiency of the device.
[0014] Furthermore, the bearing ring is welded to the outer wall of the cover plate, the output shaft of the drive motor is fixedly connected to one end of the rotating column, the drive motor is a high temperature resistant motor, and the sealing cover is fixed to the bearing ring by screws.
[0015] By adopting the above technical solution, the drive motor can drive the rotating column to rotate, thereby adjusting the flow guide cavity, and the sealing cover protects the drive motor.
[0016] Furthermore, a socket is provided on one side wall of the outer casing, and the socket is electrically connected to the heating coil.
[0017] By adopting the above technical solution, the socket can be easily connected to an external power supply mechanism, thereby providing the heating coil with the required electrical energy.
[0018] Furthermore, a thermostat is provided on one side of the socket, and the thermostat is electrically connected to both the socket and the heating coil.
[0019] By adopting the above technical solution, the temperature controller can control the heating temperature of the heating coil.
[0020] (III) Beneficial Effects
[0021] Compared with the prior art, this utility model has the following advantages:
[0022] To address the problem that existing heating plates, where the heating coil is located inside the casing, require heat to pass through the casing to heat objects placed on the plate, resulting in heat loss and affecting heating efficiency, thus hindering rapid heating and impacting the device's heating effect and performance, this invention addresses this issue by incorporating a drive motor, a rotating column, a guide cavity, and a through cavity. During heating, the drive motor rotates the rotating column 90 degrees, exposing the guide cavity. At this point, some of the heat generated by the heating coil can directly heat the object through the guide cavity, avoiding significant heat loss by passing entirely through the cover plate, effectively improving the device's heating efficiency. When not in use, the rotating column reverses to conceal the guide cavity, sealing the through cavity and protecting the heating coil from dust. This design not only provides excellent heating performance but also high operational efficiency. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0029] As shown in Figures 1-3, a high-efficiency heating plate in this embodiment includes a housing 1, inside which a heating coil 11 is installed. A cover plate 2 is fixed to the top of the housing 1. The housing 1 and the cover plate 2 can conceal the heating coil 11. The heating coil 11 can generate heat to heat objects when energized. Five sets of through cavities 5 are distributed circumferentially on the cover plate 2. A rotating column 6 is installed in each through cavity 5. Multiple sets of guide cavities 9 are arrayed on the rotating column 6. The through cavities 5 provide rotation space for the rotating column 6. When the device is not in use, the rotating column 6 can conceal the guide cavities 9, thereby sealing the through cavities 5. The device is sealed, and during use, the rotating column 6 can be rotated 90 degrees to expose the guide cavity 9. During the heating process, part of the heat generated by the heating coil 11 can be directly heated to the object through the guide cavity 9, avoiding the loss of all heat through the cover plate 2, thus effectively improving the heating efficiency of the device. A bearing ring 3 is fixed on the outside of the cover plate 2. Five sets of drive motors 10 are circumferentially distributed inside the bearing ring 3. A sealing cover 4 is set above the drive motors 10. The drive motors 10 can drive the rotating column 6 to rotate, thereby adjusting the guide cavity 9. The sealing cover 4 protects the drive motors 10.
[0030] As shown in Figures 1-3, in this embodiment, the heating coil 11 is fixed inside the outer shell 1, the cover plate 2 is fixed to the top of the outer shell 1 by screws, the through cavity 5 is formed on the cover plate 2, the rotating column 6 is rotatably installed in the through cavity 5, the guide cavity 9 is formed on the rotating column 6, the outer diameter of the rotating column 6 matches the inner diameter of the through cavity 5, the bearing ring 3 is welded to the outer wall of the cover plate 2, the output shaft of the drive motor 10 is fixedly connected to one end of the rotating column 6, the drive motor 10 is a high temperature resistant motor, and the sealing cover 4 is fixed to the bearing ring 3 by screws.
[0031] As shown in Figures 1-3, in this embodiment, a socket 7 is reserved on one side wall of the outer casing 1. The socket 7 is electrically connected to the heating coil 11. The socket 7 is convenient to be connected to an external power supply mechanism to provide the required power to the heating coil 11. A thermostat 8 is provided on one side of the socket 7. The thermostat 8 is electrically connected to both the socket 7 and the heating coil 11. The thermostat 8 can control the heating temperature of the heating coil 11.
[0032] The specific implementation process of this embodiment is as follows: In use, the device is connected to an external power source through the socket 7, and the heating temperature of the heating coil 11 is controlled by the thermostat 8. Then, the object to be heated is placed on the cover plate 2. At this time, the heating coil 11 heats up and heats the object. During the heating process, the drive motor 10 drives the rotating column 6 to rotate 90 degrees to expose the guide cavity 9. At this time, part of the heat generated by the heating coil 11 can directly heat the object through the guide cavity 9, avoiding all of it passing through the cover plate 2 and causing a large loss, effectively improving the heating efficiency of the device. At the same time, when idle, the rotating column 6 reverses to hide the guide cavity 9, thereby sealing the cavity 5 and protecting the heating coil 11 from dust. It not only has a good heating effect, but also high performance.
