The present invention relates to a cooker, and more particularly to an induction cooker.

Electronic cookers are becoming increasingly popular in that they can overcome the problems caused by the use of gas stoves, such as toxic CO gas, exhaust gas and smoke-producing pot floors.

Therefore, the present applicant intends to diversify the electronic cooker.

An object of the present invention is to provide an electronic cooker that can leave a message inside the cooker. Another object of the present invention is to provide an induction cooker that can provide a voice alarm function.

According to the present invention, the induction cooker is capable of changing an internal circuit for operating the induction cooker, a voice input unit for inputting a first audio analog signal, an analog signal to a digital signal, and converting the digital signal into a second analog signal. An audio output unit including a speech processing unit capable of converting into an analog signal, a RAM storing a digital signal, an amplifier circuit for amplifying the second analog signal, and a speaker for reproducing the amplified second analog signal, a processing unit; And a voltage stabilizing circuit for supplying an operating voltage, d, c for supplying power to the RAM, and a controller for selectively controlling the processing unit in input and output states.

The present invention will be described with reference to the accompanying drawings.

According to FIGS. 1 and 2, the induction cooker according to the present invention has an internal circuit 10 for operating an induction cooker, a voltage stabilization circuit 20, a voice processing unit 30, a memory device 40, and a voice input. A unit 50, a sound output unit 60, a control unit 70 and an operation display unit 80.

The internal circuit 10 includes five contact control switches SW0, SW1, SW2, SW3, SW4, and 17 display LEDs D1-D17, where SW3 and SW4 control the power output of the cooker. Both have 140W difference between two adjacent levels and have 8 levels indicated by D1-D8, SW1 and SW2 control the temperature of the cooking medium and the difference of 20 ° C between all two consecutive levels. And 8 levels indicated by D9-D16, SW0 can switch the power off and on even when the cooker is being cooked under “Power Output” mode or “Temperature Setting” mode and D17 when the cooker is cooking. Lights up and is in an abnormal state, i.e. if the face panel becomes very hot or the cooker is poorly dissipated, it will flash to give a look around.

The internal circuit 10 also includes transformers and rectifier circuits (not shown) for supplying d, c, power of 9V.

The voltage stabilization circuit 20 includes a resistor R1, a capacitor C1, C3, a transistor Q1, and a zener diode ZD1 to maintain d, c, power at a rated operating voltage DC9V.

The sound processing unit 30 is a model No. As an IC chip having VTVOO1, the first analog signal from the input unit 50 can be converted into a digital signal, and the digital signal can be converted into a second analog signal such as the first analog signal.

The memory unit 40 made of RAM can store and read digital signals by the processing unit 30.

The voice input unit 60 includes a microphone M1 for receiving a voice signal to filter d, c, signals and input the first a, c, analog signals to the voice processing unit 30, and a resistor R8 (R9). ) And a filtering circuit 51 comprising a capacitor C9.

The voice output unit S0 is composed of a speaker SP1 for reproducing the second analog signal and a resistor R2, R3, R7, capacitor C4, C5 and a transistor for amplifying the second analog signal before reproducing. And a two-terminal push-pull amplification circuit 61 including (Q2) and (Q3).

The control unit 70 includes an input switch SW6 for enabling the voice recording state for the cooker and an output switch SW5 for enabling the voice reproduction state.

The operation indicator unit 80 includes a resistor R11, a capacitor C10 and an indicator LED D18 and will be turned on when SW5 or SW6 is switched on to show that the processing unit 30 is in operation.

When the user wants to leave a message in the cooker, he can switch on the SW6 and speak into the microphone M1.

Thus, the analog signal filtered by the filtering circuit 51 is converted into a digital signal by the processing unit 30 and stored in the RAM 40.

When the message in the cooker is to be obtained, the audio processing unit 40 reads the digital signal stored in the RAM 40 and amplifies the signal by the amplifier circuit 61 so that the signal is reproduced by the speaker SP1. 2 Switch SW5 to convert to analog signal.

When the internal circuit 10, the processing unit 30 and the control unit 70 are electrically connected to each other, the cooker of the present invention can be equipped with a voice alarm system.

For example, if the face panel of the cooker does not want to be higher than the set temperature, the temperature in the RAM 40 is too high. If the sentence "THE TEMPERATURE IS TOO HIGH" is recorded in words, the output switch of the control unit 70 may switch on when the temperature of the cooker is higher than the set temperature and repeat the sentence.

Through the foregoing, it will be apparent to those skilled in the art how the present invention can achieve its intended purpose.
