Description

Technical Field

[0001] This utility model relates to the field of electronic equipment, and in particular to an air fryer control circuit and an air fryer. Background Technology

[0002] An air fryer uses air instead of the hot oil in a frying pan. It uses convection heating, similar to the heat from the sun, to create a rapid flow of hot air inside the sealed pot.

[0043] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.

[0044] An air fryer uses air instead of the hot oil in a frying pan. It uses convection heating, similar to the heat from the sun, to create a rapid flow of hot air inside the sealed pot. This cooks the food while also blowing away the moisture from the surface of the food, allowing it to achieve a similar effect to deep-frying without the need for boiling oil.

[0045] Currently, air fryers do not have a function to detect the operation of the fan. Whether the fan is working or not will affect the temperature control. If the fan is too far from the heating coil, it may cause the temperature to become too high, which could be dangerous.

[0046] To solve the above problems, this utility model proposes an air fryer control circuit, wherein the air fryer includes a fan.

[0047] Reference Figure 1 In one embodiment, the air fryer control circuit includes:

[0048] The fan detection circuit 20 is used to detect the rotation status of the fan and output a fan detection signal;

[0049] The main control circuit 10 has its input terminal connected to the output terminal of the fan detection circuit 20. The main control circuit 10 is used to determine the fan rotation state based on the fan detection signal when it receives the fan start signal, and to control the fan to stop working when it determines that the fan is in a non-rotating state.

[0050] In this embodiment, the fan detection circuit 20 can be composed of multiple resistors and capacitors. A receiving detection element is set in the air fryer to detect the fan's rotation state. For example, a Hall sensor can detect the motion state of an object, i.e., whether the fan is rotating. The fan detection circuit 20 then filters the electrical signal output by the detection element before outputting it to the main control circuit 10. The filtering process ensures signal stability. The main control circuit 10 can be composed of a controller and multiple electronic components such as capacitors and resistors. The controller can be a Digital Signal Processor (DSP), Programmable Logic Device (PLD), Field Programmable Gate Array (FPGA), microprocessor, MCU, or other electronic components. The main control circuit 10 can control the fan to start working when it receives a fan start signal. The fan start signal can be output by the switch button on the air fryer or sent to the main control circuit 10 wirelessly by a control terminal, such as a remote control. At this time, the main control circuit 10 will also determine the fan's rotation status based on the fan detection signal. If it is determined that the fan is not rotating, it means that the fan is malfunctioning, which will affect the temperature control of the air fryer. For example, if the fan cannot dissipate heat properly when it is not rotating, the main control circuit 10 can control the fan to stop rotating to avoid safety accidents. If it is determined that the fan is rotating, the main control circuit 10 will control the fan to continue working.

[0051] This invention utilizes a fan detection circuit 20 and a main control circuit 10 to construct an air fryer control circuit. The fan detection circuit 20 detects the fan's rotation status and outputs a fan detection signal to the main control circuit 10. The input terminal of the main control circuit 10 is connected to the output terminal of the fan detection circuit 20. Upon receiving a fan-on signal, the main control circuit 10 determines the fan's rotation status based on the fan detection signal and stops the fan when it determines that the fan is not rotating. Thus, this solution allows the fan detection circuit 20 to detect the fan's rotation status. When the main control circuit 10 receives a fan-on signal, it controls the fan to rotate. If the fan is not rotating, it indicates a malfunction, and the main control circuit 10 can stop the fan to prevent accidents.

[0052] Reference Figure 2 In one embodiment, the fan detection circuit 20 includes a Hall sensor interface P3, a first resistor R1, a second resistor R2, a first capacitor C1, and a second capacitor C2. The first end of the first resistor R1 and the first end of the first capacitor C1 are connected to the input terminal of the main control circuit 10, and the second end of the first capacitor C1 is grounded. The second end of the first resistor R1 and the first end of the second resistor R2 are connected to the second end of the Hall sensor interface P3, and the second end of the second resistor R2 is used to connect to the power supply. The first end of the second capacitor C2 is connected to the third end of the Hall sensor interface P3, and the second end of the second capacitor C2 and the first end of the Hall sensor are grounded. The Hall sensor interface P3 is used to connect to the Hall sensor.

[0053] In this embodiment, the first resistor R1 can act as a current-limiting resistor, the second resistor R2 can act as a pull-up resistor, the Hall sensor interface P3 can be connected to the Hall sensor installed in the air fryer to receive the detection signal output by the Hall sensor; and the fan detection circuit 20, through the filtering of the pull-up resistor and the first capacitor C1 and the second capacitor C2, enables the fan detection circuit 20 to detect the Hall sensor output signal efficiently and stably, and will not produce false alarms that would cause the air fryer to malfunction.

[0054] Reference Figure 1 In one embodiment, the air fryer control circuit further includes:

[0055] A fan drive circuit 30 is provided, the input terminal of which is connected to the output terminal of the main control circuit 10. The output terminal of the fan drive circuit 30 is used to connect to the fan. The fan drive circuit 30 is used to drive the fan to work when it receives the fan control signal output by the main control circuit 10.

[0056] In this embodiment, the wind turbine drive circuit 30 can be composed of multiple capacitors, resistors, thyristors, optocouplers, and other electronic components. The specific circuit structure can be found in [reference needed]. Figure 3 The circuit is configured to control the fan's on / off state via a thyristor and to isolate the high-voltage and low-voltage circuits via optocoupler isolation, making the circuit safer and more reliable. Thus, the fan drive circuit 30 can drive the fan to operate when it receives a fan control signal output from the main control circuit 10; for example, it can start the fan from rotating when it receives a high-level electrical signal and stop the fan from rotating when it receives a low-level electrical signal.

[0057] In one embodiment, the air fryer further includes a heating wire, see reference. Figure 1 The air fryer control circuit also includes:

[0058] Temperature detection circuit 40, the output terminal of which is connected to the input terminal of the main control circuit 10, is used to detect the temperature of the heating wire and output a temperature detection signal to the main control circuit 10.

[0059] The main control circuit 10 is used to determine the temperature of the heating wire based on the temperature detection signal when it receives the heating wire turn-on signal, and to control the heating wire to stop working when it determines that the heating wire temperature is lower than the threshold temperature.

[0060] In this embodiment, the temperature circuit can be composed of multiple resistors and capacitors. A thermistor is installed in the air fryer to detect the heating temperature of the heating wire. The temperature detection circuit 40 outputs the detection signal from the thermistor to the main control circuit 10. The main control circuit 10 can control the heating wire to start working when it receives a heating wire activation signal. The heating wire activation signal can be output by the switch button on the air fryer or sent to the main control circuit 10 wirelessly by a control terminal, such as a remote control. At this time, the main control circuit 10 will also determine the heating status of the heating wire based on the temperature detection signal. If the heating wire temperature is determined to be below the threshold temperature, it means that the thermistor has failed, which will affect the temperature control of the air fryer. For example, if the thermistor is damaged, its resistance will not change, and it will not trigger open circuit or short circuit alarms, making temperature control impossible. The heating coil will continue to work, resulting in very high temperatures, which may easily lead to safety accidents. At this time, the main control circuit 10 can control the heating wire to stop rotating to avoid safety accidents.

[0061] Reference Figure 1 In one embodiment, the air fryer control circuit further includes:

[0062] A heating wire driving circuit 50 is provided, wherein the input terminal of the heating wire driving circuit 50 is connected to the output terminal of the main control circuit 10, and the output terminal of the heating wire driving circuit 50 is connected to the heating wire. The heating wire driving circuit 50 is used to drive the heating wire to work when it receives a heating control signal output by the main control circuit 10.

[0063] In this embodiment, the heating wire driving circuit 50 can be composed of multiple capacitors, resistors, and electronic components such as diodes, transistors, and relays. The specific circuit structure can be found in [reference needed]. Figure 4The heating coil is switched on and off via a relay to achieve temperature control, a more cost-effective method. The heating wire drive circuit 50 can then drive the heating wire to operate when it receives a heating control signal from the main control circuit 10. For example, it starts heating when it receives a high-level electrical signal and stops heating when it receives a low-level electrical signal.

[0064] Reference Figure 5 In one embodiment, the air fryer control circuit further includes:

[0065] A first encoder A, the output terminal of which is connected to the input terminal of the main control circuit 10, is used to output a working time adjustment signal to the main control circuit 10 when triggered;

[0066] The second encoder B, the output terminal of the second encoder B is connected to the input terminal of the main control circuit 10, and the second encoder B is used to output a temperature adjustment signal to the main control circuit 10 when triggered;

[0067] The encoder selection circuit 60 has an input terminal for connecting to a selection button and an output terminal for connecting the first encoder A and the second encoder B. The encoder selection circuit 60 is used to select the first encoder A or the second encoder B to operate based on the encoder selection signal output when the selection button is triggered.

[0068] In this embodiment, the air fryer can be equipped with selection buttons. When the user triggers a selection button, an encoder selection signal will be output. For example, two selection buttons can be set, corresponding to the first encoder A and the second encoder B; or one selection button can be set, pressing the first encoder A and pressing it again corresponds to the second encoder B. The specific selection buttons can be set according to the actual situation and user needs. The working voltage and working time of the air fryer can be adjusted by using the first encoder A and the second encoder B. First, select the first encoder A or the second encoder B by selecting the selection button. Rotating the encoder will adjust the corresponding value. Selecting the first encoder A adjusts the working time, and selecting the second encoder B adjusts the temperature. The encoder selection circuit 60 can be composed of multiple electronic components such as resistors and capacitors. The specific circuit structure can be referred to Figure 6 set up.

[0069] Reference Figure 5 In one embodiment, the air fryer control circuit further includes:

[0070] The digital tube display circuit 70 has its input terminal connected to the output terminal of the main control circuit 10. The main control circuit 10 is used to control the digital tube display circuit 70 to work when controlling the fan to work.

[0071] In this embodiment, the specific circuit structure of the digital tube display circuit 70 can be referred to... Figure 7 In this configuration, the main control circuit 10 can control the digital display circuit 70 to operate while controlling the air fryer's fan and heating element. The digital display can show the current temperature, target temperature, and remaining time. The default setting is to show the current temperature. Users can also view the current temperature and time by pressing the time or temperature buttons. Specific display and button settings can be customized according to user needs.

[0072] Reference Figure 5 In one embodiment, the air fryer control circuit further includes:

[0073] The power supply circuit 80 has its output terminal connected to the power supply terminal of the fan detection circuit 20 and the power supply terminal of the main control circuit 10. The power supply circuit 80 is used to provide operating voltage to the fan detection circuit 20 and the main control circuit 10.

[0074] In this embodiment, the power supply circuit 80 can be implemented using a DC-DC circuit or a power chip. The power supply circuit 80 can convert the external power supply voltage into a suitable operating voltage for the fan detection circuit 20 and the main control circuit 10, so as to prevent the fan detection circuit 20 and the main control circuit 10 from receiving too high an operating voltage and causing damage to the devices, or receiving too low an operating voltage and causing the devices to malfunction. The power supply circuit 80 can also have a built-in battery pack to provide operating voltage to the fan detection circuit 20 and the main control circuit 10.
