Touch sensing apparatus based on ultrasonic wave, cooking apparatus, and home appliance including the same

The present invention relates to the ultrasonic-based touch-sensing apparatus, cooking apparatus having the same, and a home appliance. The cooking apparatus, and a home appliance for ultrasound-based touch-sensing apparatus, including the same in accordance with an embodiment of the present invention is disposed between the first plate and the first plate and a second plate spaced apart, the first and the second plates and, the first plate corresponding to the touch input, and the piezoelectric element outputting an electric signal based on the electric signal from the piezoelectric element and the ultrasonic wave output unit for outputting an ultrasonic wave, and a plurality of microphones for receiving the ultrasonic wave, a plurality of on based on the sound signal collected by the microphone, and a processor for calculating the position of the touch input on the first plate. Accordingly, it is possible to improve the user's ease of use.
