Description

Technical Field

[0001] This utility model relates to the field of electric ceramic stove technology, specifically to an electric ceramic stove temperature control system. Background Technology

[0002] In the catering industry, ceramic cooktops are the most commonly used cooking equipment. The accuracy and intelligence of their temperature control directly affect work efficiency and food quality. Currently, traditional ceramic cooktops have relatively simple temperature control systems with low sensor sensitivity, making them unable to effectively adapt to changes in power and temperature requirements in different scenarios. Traditional ceramic cooktops mostly rely on manual or simple mechanical temperature control, requiring users to frequently adjust the temperature settings manually, which is cumbersome, time-consuming, and labor-intensive. Furthermore, temperature measurement accuracy is difficult to guarantee over the long term, and sensors are easily damaged under abnormal operating conditions, making maintenance and replacement extremely inconvenient. Utility Model Content

[0003] This application provides a temperature control system for an electric ceramic stove, and the technical solution provided is as follows:

[0004] An electric ceramic cooker temperature control system includes a housing, a circuit board, and a magnetic temperature sensing module. The circuit board is installed inside the housing. A control module is mounted on the circuit board. The housing has a display screen and touch buttons. The display screen and touch buttons are electrically connected to the control module. The magnetic temperature sensing module includes a temperature sensor, a thermistor, and a bracket. One end of the bracket is rotatably mounted inside the electric ceramic cooker. The temperature sensor and the thermistor are mounted at the other end of the bracket. When the thermistor is magnetic, it contacts the inner liner of the electric ceramic cooker. The temperature sensor is electrically connected to the control module.

[0005] Furthermore, the temperature sensor is a thermistor sensor.

[0006] Furthermore, a buzzer is installed inside the housing, and the buzzer is electrically connected to the control module.

[0007] Furthermore, it also includes a wireless communication module, which is electrically connected to the control module.

[0008] Furthermore, the control module is covered with a metal cover, which is fixedly connected to the housing by a metal plate.

[0009] Furthermore, a heat dissipation fin is provided on the lower surface of the housing.

[0010] Furthermore, both the metal cap and the metal plate are made of copper.

[0011] Furthermore, thermally conductive silicone grease is filled between the metal cap and the control module.

[0012] Furthermore, it also includes a liquid detection module, which is mounted on the housing and is electrically connected to the control module.

[0013] Compared with the prior art, the beneficial effects of this application are:

[0014] 1. This utility model provides a temperature control system for an electric ceramic stove. Through the structural design of the thermistor ferrite and the rotating bracket, it ensures that the temperature sensor can maintain close and stable physical contact with the surface of the inner pot of the electric ceramic stove, which greatly reduces the thermal resistance caused by the installation gap and can accurately detect the temperature of the bottom of the pot.

[0015] 2. The liquid detection module can monitor the furnace surface for liquid overflow in real time. Once liquid is detected, it can immediately notify the control module to issue an alarm and cut off heating. This effectively prevents liquid from seeping into the machine and causing short circuits, component corrosion, or more serious electrical safety accidents. It also avoids the hassle of cleaning up spills, greatly improving the safety and reliability of the product. Attached Figure Description

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] See Figure 1 This utility model provides a temperature control system for an electric ceramic stove, including a housing 1, a circuit board 2, and a magnetic temperature sensing module. The circuit board 2 is installed inside the housing 1, and a control module is mounted on the circuit board 2. The housing 1 has a display screen 3 and touch buttons 4, both electrically connected to the control module. The display screen 3 is an LED display screen, connected to the control module via the I2C communication protocol, used to display temperature information and receive user input commands. The touch buttons 4 are capacitive touch buttons, connected to the control module via a GPIO interface, used to set target temperature values ​​or operating mode commands. In actual use, the number and functions of the touch buttons 4 can be flexibly adjusted. In this embodiment, the button functions include temperature setting, mode switching, and start / stop. The magnetic temperature sensing module includes a temperature sensor 5, a thermistor ferrite 6, and a bracket 7. One end of the bracket 7 is installed inside the electric ceramic stove via a rotating mechanism, and the other end is equipped with the temperature sensor 5 and the thermistor ferrite 6. When the thermistor ferrite 6 is magnetic, the temperature sensor 5 and the thermistor ferrite 6 can come into contact with the inner liner of the ceramic cooker, thereby achieving accurate temperature detection. The temperature sensor 5 is a thermistor sensor, model NTC10KB3950, which can sense the temperature changes of the inner liner of the ceramic cooker in real time and transmit the data to the control module.

[0024] In the specific structure of the magnetic temperature sensing module, one end of the bracket 7 is installed inside the ceramic cooker via a rotating shaft, while the other end is fixed with a temperature sensor 5 and a thermistor ferrite 6. Thermistor ferrite 6 is a material with magnetic temperature characteristics. When the temperature is below its Curie point, thermistor ferrite 6 exhibits strong magnetism, allowing the temperature sensor 5 and the thermistor ferrite 6 to adhere to the surface of the ceramic cooker's inner liner, ensuring close contact between the temperature sensor 5 and the inner liner, thereby improving the accuracy of temperature detection. When the temperature is above the Curie point, the thermistor ferrite 6 loses its magnetism, and the bracket 7 rotates under gravity or other external forces, causing the temperature sensor 5 to detach from the inner liner surface, preventing damage to the temperature sensor 5 due to high temperatures. This design not only improves the reliability of temperature detection but also extends the service life of the temperature sensor 5.

[0025] The control module is covered by a metal cover 8, which is fixedly connected to the housing 1 by a metal plate 9. Both the metal cover 8 and the metal plate 9 are made of copper, which has good thermal conductivity. Thermal grease is filled between the metal cover 8 and the control module to quickly conduct the heat generated by the control module during operation to the metal cover 8, and then dissipate the heat to the outside of the housing 1 through the metal plate 9, thereby effectively reducing the operating temperature of the control module and improving the stability and reliability of the system.

[0026] The lower surface of the housing 1 is equipped with heat dissipation fins. The number and arrangement of the heat dissipation fins have been optimized to significantly increase the heat dissipation area of ​​the housing 1 and further improve the heat dissipation performance of the system. The heat dissipation fins are made of aluminum alloy, which has a high thermal conductivity and can quickly conduct heat from inside the housing 1 to the external environment, thereby ensuring that the temperature control system of the electric ceramic stove will not malfunction due to overheating during long-term operation.

[0027] The ceramic cooktop temperature control system also includes a wireless communication module, a buzzer, and a liquid detection module. The wireless communication module is electrically connected to the control module for remote monitoring and operation. Users can remotely monitor and control the cooktop's operating status using external devices such as smartphones or tablets. For example, when in another room of the house, users can view the current temperature, set temperature, and operating mode via a mobile application and send commands to the wireless communication module. Upon receiving the command, the wireless communication module transmits it to the control module for parsing and execution, while simultaneously feeding back the cooktop's current status information to the external device. The buzzer is electrically connected to the control module via a relay. When the cooktop reaches the set temperature or an abnormal situation occurs, the control module drives the buzzer to emit a warning sound via the relay, alerting the user. The relay controls the buzzer's operation based on the commands output by the control module, thus achieving automated audio prompting. This design not only improves system safety but also enhances the user experience. The liquid detection module, located on the housing 1, is used to detect any liquid leaks inside the ceramic cooktop. When the liquid detection module detects liquid, it sends a signal to the control module. The control module then sounds an alarm via a buzzer to remind the user to take timely action and avoid safety hazards caused by liquid leakage.

[0028] One implementation process of the electric ceramic stove temperature control system of this utility model is as follows: When the electric ceramic stove starts working, the thermistor ferrite in the magnetic temperature sensing module becomes magnetic because its temperature is below the Curie point. The temperature sensor and the thermistor ferrite are adsorbed onto the surface of the inner liner of the electric ceramic stove, detecting the inner liner temperature in real time and transmitting the data to the control module. Based on the received temperature data, the control module displays the current temperature on the screen and adjusts the heating power of the electric ceramic stove according to the target temperature set by the user via touch buttons. If the temperature exceeds the safe range, a buzzer will sound an alarm to alert the user. Simultaneously, the wireless communication module can transmit the temperature data to the user's terminal device in real time, facilitating remote monitoring and operation. When the liquid detection module detects a liquid leak inside the electric ceramic stove, it sends a signal to the control module. The control module then sounds an alarm via a buzzer and notifies the user via the wireless communication module.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
