Description

Frying bowl using ultrasonic wave by piezoelectric element and magnetostrictive element {A BOWL FOR FRIED USING THE ULTRA SONIC WHICH IS VIBRATED FROM MAGNETOSTRICTION OR PIEZO OSCILLATOR}

The present invention relates to a frying vessel using ultrasonic waves, and more particularly, to piezoelectric elements and magnetostrictive elements for rapidly increasing the temperature of the frying oil embedded in the frying vessel by using the outgoing vibration frequency of the piezoelectric element and the magnetostrictive vibration element. It relates to a frying bowl using ultrasonic waves.

In general, the food for frying is to heat the temperature of the oil from about 150 ℃ to 400 ℃, and then the food is cooked by the heated oil, in this case, the method of heating the oil using gas or electric energy The hot air balloon is used, and the frying apparatus according to the gas method includes a container 101 filled with oil 103 as shown in FIG. 1, heating means 107 and the oil provided at a lower end of the container 101. It consists of a thermometer 109 for measuring the temperature of 103. Then, according to the measured value of the thermometer 109, a predetermined control device 111 for controlling the fire reduction function of the heating means 107 is added.

After igniting the heating means 107 through the control device 111, it continuously measures the temperature of the oil 103 measured from the thermometer 109, the oil (103) detected by the thermometer 109 When the temperature of) exceeds the reference value, the heating means 107 is extinguished so that the temperature of the oil 103 can be maintained within the reference range. Therefore, when the temperature of the oil 103 detected by the thermometer 109 is below the reference value, the control device 111 instructs the ignition of the heating means 107 to perform the normal on / off switching control.

In this way, since the frying apparatus used in the prior art depends entirely on the heating means 107, the temperature of the oil 103 is not only consumed a lot of time for the temperature of the oil 103 to rise to the reference value, but also the oil 103 Due to its own viscosity, when a large amount of food is fried, the oil 103 is easily turbid and the number of times of use is reduced. This is because food debris in the frying of food is internalized in the container 101, thereby causing a problem of deteriorating the taste of the food by preventing the food from being cooked evenly.

The present invention was devised to solve such a problem, and the purpose of the present invention is not only to save fuel of the frying device, but also to cook the fried food faster and improve the taste, and to prevent the oil from easily turbid. The present invention provides a frying vessel using ultrasonic waves by piezoelectric elements and magnetostrictive elements.

Hereinafter, the present invention will be described in detail based on the accompanying drawings.

Figure 2 is a block diagram showing an example of a frying bowl according to the gas heating method of the present invention. First, referring to FIG. 2, a frying container 301 having a predetermined capacity and an ultrasonic transmitter M for generating ultrasonic waves are mounted on the side surface of the frying container 301 and a lower end of the frying container 301. And a heating device 305 for heating the oil 303 and a thermometer 307 for measuring the temperature of the oil 303, and based on the detected temperature of the thermometer 307, the ultrasonic transmitter M Control device 309 for controlling drive.

The system 300 of the frying vessel made in this way, in order to maintain the temperature of the oil 303 is approximately 150 ℃ to 400 ℃, and continuously heating through the heating device 305, Ultrasonic waves are generated using the ultrasonic transmitter (M). The ultrasonic wave vibrates the oil 303 on the outer circumferential surface of the frying container 301 at a frequency within a range of 8 kHz to 40 kHz. Of course, the ultrasonic transmitter (M) used in the present invention includes a piezoelectric element using a ceramic of any one of a number of magnetostrictive elements (99.9Ni, 96Ni4Co, 50Ni50Fe, 45Ni55Fe, 49Co49Fe2V, ....) developed to date. The device may be used.

Therefore, the ultrasonic transmitter (M) is applied to the vibration energy through the ultrasonic wave to the oil (303) to weaken the viscosity of the oil (303) so that the heat energy flowing from the heating device (305) is easily transferred. This causes the temperature of the oil 303 to quickly reach the reference value, and is to break the food debris particles splashed by the oil 303 by ultrasonic vibration to prevent the oil 303 from easily turbid.

On the other hand, the control device 309 determines whether the temperature of the oil 303 measured from the thermometer 307 reaches the reference value, when the temperature of the oil 303 measured by the thermometer 307 reaches the reference value The operation of the heating device 305 and the ultrasonic transmitter (M) is stopped, and when the temperature of the oil (303) is lower than the reference value, the heating device (305) and the ultrasonic transmitter (M) is started, Ensure the temperature maintains the baseline.

And, the ultrasonic transmitter (M) is preferably installed at the bottom 25% of the surface of the oil 303 for the purpose of the present invention, the magnetostrictive element used in the ultrasonic transmitter (M) is a patent application 98-58546, "Method for Manufacturing Sheets and Wires with Excellent Machinability and Magnetostrictive Properties," and Patent Application No. 99-0003033, "Drivers and Methods of Magnetostrictive Vibrators Using Pulse Width Modulation."

Looking at the driving of the control device 309 as follows.

3 is a block diagram showing a control device. First, referring to FIG. 3, the controller 309 includes a controller 405 for outputting a variable duty control signal based on generation of a predetermined counting signal and programmed data, and a plurality of data from the controller 405. A pulse width modulator 411 that is applied to generate a triangle wave signal having a variable duty, a buffer unit 412 for outputting the output signal of the pulse width modulator 411 as a standardized pulse signal, and the buffer unit 412 It consists of a driving unit 413 for driving the ultrasonic transmitter (M) based on the output signal applied from).

In addition, a temperature sensor 401 for measuring the temperature of the oil 303 is connected to an input terminal of the controller 405, and the controller 405 is driven according to a driving program of the magnetostrictive vibrator M stored in the memory 402. A microcomputer 403 for controlling the system and an oscillator 404 for allowing the microcomputer 403 to perform synchronized control.

In addition, the pulse width modulator 411 may include a die converter 408 including a first die converter 406 and a second die converter 407, and an output of the first die converter 406. A triangular wave signal for generating a triangular wave signal 409 and a triangular wave signal applied by the triangular wave generator 409 and an analog duty ratio setting signal applied by the second die conversion unit 408 are applied. The duty modulator 410 is configured to vary the duty of.

Hereinafter, the operation according to the above configuration will be described.

First, after the oil 303 is filled in the container 301, a user ignites the heating device 305 and performs switching to operate the ultrasonic transmitter M, for example, a magnetostrictive vibrator or a piezoelectric element. Then, the drive device 400 of the magnetostrictive vibrator measures the current temperature of the oil 303 through the temperature sensor 401, and determines whether the measured temperature is a set temperature, that is, a temperature between 150 ° C and 400 ° C. Here, when the controller 405 determines that the temperature sensed by the temperature sensor 401 is lower than or equal to the set temperature, driving of the ultrasonic transmitter M is started.

The microcomputer 403 reads the control program of the ultrasonic transmitter M stored in the memory 402 and outputs the data corresponding to the resonance frequency 8KHz-40KHz through the first port P1, and at the same time, the duty A pulse signal having a ratio of 100% is output through the second port P2. Accordingly, the first die converter 406 converts the frequency signal applied from the first port P1 of the microcomputer 403 into an analog signal and supplies the analog signal to the triangular wave generator 409.

The triangular wave generator 409 generates and outputs a triangular wave signal corresponding to the frequency to the duty modulator 410. The second die converter 407 connected to the second port P2 of the microcomputer 403 receives a pulse signal having a duty ratio of 100%, that is, a DC signal, and transmits the DC signal to the duty modulator 410, thereby providing a duty. The modulator 410 generates a triangular wave frequency corresponding to the duty ratio currently flowing from the second port P2. That is, in this case, a triangular wave having a 100% duty ratio is transmitted to the buffer unit 410.

Accordingly, the triangular wave signal through the buffer unit 412 is converted into a pulse wave signal (direct current signal) having a duty ratio close to 100% and is supplied to the driving unit 413, and the driving unit 413 is boosted by the driving voltage of the ultrasonic transmitter M. Send it. This is because the initial driving of the ultrasonic transmitter (M) is made by a direct current signal, the direct current signal is made by the oscillator 404 for approximately 50 kHz. Therefore, a DC signal is supplied to the buffer unit 412 for 50, and a DC signal of a predetermined voltage is supplied to the ultrasonic wave transmitter M through the driving unit 413. The voltage here is DC 12-70 volts, to self saturate the ultrasonic transmitter (M).

When 50 kHz has elapsed due to the initial operation of the ultrasonic transmitter M, the microcomputer 403 generates a control signal according to duty modulation through the second port P2. The duty ratio decreases for a predetermined time starting from 85%-50% to approximately 2.5%-0%, and converts and outputs the voltage corresponding to the duty ratio through the second die conversion unit 408. The duty modulator 410 changes the duty of the triangular wave according to the duty ratio and transmits the duty to the buffer unit 412. The buffer unit 412 compensates the input signal with the rated signal, and converts the output signal into the rated capacity of the ultrasonic transmitter M by the driving unit 413.

Thus, the ultrasonic wave of 15KHz to 40KHz radiated from the ultrasonic transmitter (M) penetrates the vessel 301 to vibrate the oil 303 to raise the temperature. The vibration of the oil 303 by the ultrasonic wave is to make food quickly and evenly cooked through the principle of caption, the principle of wave, and the principle of increasing particle surface, including the principle of vibration. In addition, through the above-mentioned principles, the reverse osmosis phenomenon, in which food water does not drain, occurs, thereby lowering the oil content of the food to maintain its original taste, and to reduce fuel consumption and debris oil for a long time. Will be.

On the other hand, in the present application, but one example to heat the frying bowl through a gas method, heating the frying bowl through a heating wire also does not deviate from the gist of the present invention, in this case the position of the ultrasonic transmitter (M) is oil (303) It does not need to be located 25% of the surface of). And although the method of driving the ultrasonic transmitter (M) has been described in the PWM method, even if the ultrasonic wave output from 15KHz to 40KHz using the pulse wave method or impulse method does not deviate from the gist of the present invention, of course, One transmitter (M) per 1 m 2 of the vessel 301 can be installed to increase the effect.

The present invention described above, by mounting the magnetostrictive vibrator to the side portion of the frying container to radiate ultrasonic waves from the magnetostrictive vibrator together with the heating means, so that the oil can be easily heated by weakening the viscosity of the oil by the vibration energy, heat saving effect To obtain, not only the debris particles of food by ultrasonic vibration energy is made to prevent the oil from becoming dirty, there is an effect of improving the taste of the food.

Although the present invention has been shown and described with respect to a specific preferred embodiment, the present invention is not limited to the above embodiment, the field to which the subject innovation belongs without departing from the gist of the subject innovation claimed in the utility model registration claims Anyone of ordinary skill in the art would be able to make various variations.
