Background technique

As the degree of intelligence of cooking utensils continues to increase, a large number of electronic components are integrated in the cooking appliance. Since the operating temperature of the cooking appliance is usually as high as 90 ° C to 100 ° C, the operating temperature of the electronic component is much lower than the cooking temperature. Therefore, the cooking temperature may seriously affect the normal operation of electronic components (such as IGBT, bridge stack, choke, coil disk).

In the related art, the fan is usually set to operate at a constant speed, and the heat generating component in the cooking appliance is dissipated, and the ambient temperature of the area where the heat generating component is located is not taken into consideration.

Therefore, if the operation is still performed at a constant speed, the power consumption of the cooking appliance is increased. On the other hand, when the ambient temperature is higher than the ambient temperature When it is high, if it is still running at a constant speed, the heat dissipation efficiency cannot be further improved, thereby affecting the stable operation of the heat generating component, and may cause malfunction of the cooking appliance or cooking interruption.

Therefore, the fan FAN is not frequently turned on and off, thereby avoiding the current impact caused by the frequent start of the fan FAN, and improving the safety and reliability of the fan FAN.

In addition, the fan design is protected by a large number of protection and compensation circuits, thereby saving circuit design costs. Finally, since the same I/O interface, that is, the fan FAN and the buzzer BL031 are simultaneously driven by the drive control terminal DRV, and the driving signals of the two do not affect each other, chip resources and circuit volume can be saved.

As an optional embodiment, the power release module includes: a first diode D082, a first resistor R083, and a capacitor C081;

Correspondingly, the driving control terminal DRV is respectively connected to the anode of the first diode D082 and one end of the first resistor R083; the cathode of the first diode D082 and the other end of the first resistor R083 are simultaneously connected to one end of the capacitor C081, At the same time, it is connected with the B pole of the transistor Q081; the other end of the capacitor C081 is grounded at the same time as the E pole of the transistor Q081;

The conduction voltage drop of the first diode D082 is smaller than the conduction voltage drop between the B pole and the E pole of the transistor Q081.

In the above driving circuit, the buzzer BL031 may be a passive buzzer, and an alternating signal is generated to generate a buzzer sound. The fan FAN is a DC fan, and can be operated by a DC signal. The transistor Q081 is used to switch the fan FAN, which is not specifically limited in the embodiment of the present invention. The first resistor R083 and the capacitor C081 constitute an RC filter circuit for slowing the rise time of the high level when the drive control terminal DRV outputs an AC signal. The power supply end can supply power to the fan FAN, such as the power supply end of the 18V, which is not specifically limited in this embodiment of the present invention.

The driving control terminal DRV is used for outputting a driving signal, and the driving signal may be an alternating current level of a DC low level, a DC high level or a high level, which is not specifically limited in the embodiment of the present invention. The fan FAN is driven by a DC high level, and the buzzer BL031 is driven by alternating high and low AC levels. When the drive control terminal DRV outputs a DC high level, the fan FAN operates, and the buzzer BL031 does not generate a buzzer. When the drive control terminal DRV outputs a DC low level, the fan FAN does not work, and the buzzer BL031 does not generate a buzzer.

When the drive control terminal DRV outputs alternating high and low AC levels, the fan FAN does not work, and the buzzer BL031 generates a buzzer. In the period in which the high level is output, the drive control terminal DRV charges the capacitor C081 through the first resistor R083. As shown in Figure 6, the voltage of capacitor C081 rises exponentially.

During the output low period, the capacitor C081 is discharged through the first diode D082, that is, the first diode D082 provides a release loop for the voltage on the capacitor C081, and the discharge capacitor C081 outputs a high voltage at the drive control terminal DRV. The charge stored during the flat period. The conduction voltage drop of the first diode D082 is smaller than the conduction voltage drop between the B pole and the E pole of the transistor Q081, and the voltage after the capacitor C081 is charged is always smaller than the corresponding poles of the B pole and the E pole of the transistor Q081. Pressure drop. The conduction voltage drop corresponding to the B and E poles of the transistor Q081 may be 0.7V, and the first diode D082 may be a Schottky diode and the conduction voltage drop is 0.3V, which is not specifically described in this embodiment of the present invention. limited.

Through the above two conditions, the transistor Q081 can not be turned on at all times, that is, when the buzzer is in operation, the fan FAN does not frequently turn on and off as the drive control terminal DRV outputs high and low alternating AC levels, thereby not It will generate current surge, which can ensure the safety and reliability of the fan FAN. It should be noted that, by controlling the frequency of the AC signal, the voltage after the capacitor C081 is charged is always smaller than the voltage drop corresponding to the B pole and the E pole of the transistor Q081, which is not specifically limited in the embodiment of the present invention.

For example, the conduction voltage drop corresponding to the B pole and the E pole of the transistor Q081 is 0.7 V, and the conduction voltage drop of the first diode D082 is 0.3 V as an example. If the drive control terminal DRV outputs an AC level of 4Khz, the high and low level alternate periods are 250us. Among them, the high level in one cycle corresponds to 125us, and the low level in one cycle corresponds to 125us. During a high level of 125 us, the drive control terminal DRV charges the capacitor C081 through the first resistor R083, and the voltage of the capacitor C081 rises exponentially. However, due to the relatively short time, after 125us, the voltage rises less than 0.7v, which means that the conduction voltage drop corresponding to the B and E poles of the transistor Q081 is not reached. During a low level of 125 us, capacitor C081 begins to discharge rapidly through the first diode D082. After the above-mentioned cycle, the voltage on the capacitor C081 is always less than 0.7v, and the transistor Q081 is always unable to conduct, so that the fan FAN is not frequently turned on and off.

The circuit provided by the embodiment of the present invention, when the driving control terminal DRV outputs the alternating high and low alternating current levels, during the period of outputting the high level, the driving control terminal DRV charges the capacitor C081 through the first resistor R083 and the voltage after the capacitor C081 is charged. It is always smaller than the on-voltage drop corresponding to the B and C poles of the transistor Q081. During the output low period, the capacitor C081 is discharged through the first diode D082, so that the voltage on the capacitor C081 is always lower than the transistor Q081. The corresponding conduction voltage drop, the transistor Q081 is always unable to conduct. Therefore, the fan FAN is not frequently turned on and off, thereby avoiding the current impact caused by the frequent start of the fan FAN, and improving the safety and reliability of the fan FAN.
