Title: Cooking apparatus
Inventor: UMEKAGE YASUHIRO
IPC: F24C7/02
Filed: 1996-01-18
Abstract: PROBLEM TO BE SOLVED: To inform a cooker having a bad ear of a cooking state simply by detecting a sound of cooking a food, processing the detected sound, and outputting the processed data acoutically and visually. SOLUTION: When water is boiled with a stove, for example, as hot water becomes high temperature, a boiling sound is produced. However, an aged person is difficult to hear the sound owing to lowering of hearing capability and hence he can not decide that the water is boiled. Thereupon, the boiling sound is received by a microphone 15 and is amplified to a sound pressure level of 20dB through a power amplifier 17 to facilitate the sound. Further, a cooking sound is expressed visually as image data and is transmitted. More specifically, color change output means 27 is used as an indication device to change the color in response to the sound pressure level of the cooking sound received by the microphone 15 whereby a cooking state can be transmitted. Hereby, even a cooker having a bad ear can easily cook.

CONSTITUTION:The signal sent from the signal source 1 is amplified by the amplifier 2 and the supplied to the B-class push-pull circuit 11 via the DC blocking capacitor 13 to be delivered to the output terminal 4 via the DC blocking capacitor 3. The base potential (a) of the NPN transistor 18 is higher than the power supply voltage VCC by the forward voltage of diode, and the base potential (b) of the PNP transistor 19 becomes VCC-/2-VBE. The DC potential at the point C serving as  an output is held at VCC/2, and the bias power source having the voltage of 1/2VCC is applied to the point C via the resistances 20. Thus no fluctuation is caused to the DC potential at the point C even by giving an on/off control the switching FET12 and then giving a control of nonconduction/conduction to the circuit 11. As a result, the shock noise can be prevented completely at the terminal 4.
